    The sewer system for the Greater Copenhagen area covers an area of 4460 ha contributing to the runoff. The total area serves in total 8 municipalities, however it is dominated by the areas in the City of Copenhagen proper. The catchments merge into interceptors, which feed two large treatment plants. The effluent from the two treatment plants discharges during dry weather to Oresund, the sound between Denmark and Sweden. This large system has been analysed for selected scenarios with respect to handling runoff in an optimal way in order to minimise the loads on the most sensitive receiving waters and optimising treatment plant performance.

    One of the key climate change factors, temperature, has potentially grave implications for human health. We report the first attempt to investigate the association between the daily 3-hour maximum apparent temperature (Tappmax) and respiratory (RD), cardiovascular (CVD), and cerebrovascular (CBD) emergency hospital admissions in Copenhagen, controlling for air pollution. The study period covered 1 January 2002−31 December 2006, stratified in warm and cold periods. A case-crossover design was applied. Susceptibility (effect modification) by age, sex, and socio-economic status was investigated. For an IQR (8°C) increase in the 5-day cumulative average of Tappmax, a 7% (95% CI: 1%, 13%) increase in the RD admission rate was observed in the warm period whereas an inverse association was found with CVD (−8%, 95% CI: −13%, −4%), and none with CBD. There was no association between the 5-day cumulative average of Tappmax during the cold period and any of the cause-specific admissions, except in some susceptible groups: a negative association for RD in the oldest age group and a positive association for CVD in men and the second highest SES group. In conclusion, an increase in Tappmax is associated with a slight increase in RD and decrease in CVD admissions during the warmer months. PMID:21829550

    Like most other places, European metropolitan areas will face a range of climate-related challenges over the next decades that may influence the nature of urban life across the continent. Under future urbanization and climate change scenarios the well-being and comfort of the urban population might become progressively compromised. In urban areas, the effects of the warming climate will be accelerated by combination of Urban Heat Island effect (UHI) and extreme heat waves. The land cover composition directly influences atmospheric variability, and can either escalate or downscale the projected changes. Vegetation, forest ecosystems in particular, are anticipated to play an important role in modulating local and regional climatic conditions, and to be vital factor in the process of adapting cities to warming climate. This study investigates the impact of forest and land-cover change on formation and development of temperature regimes in the Copenhagen Metropolitan Area (CPH-MA). Potential to modify the UHI effect in CPH-MA is estimated. Using 2009 meteorological data, and up-to-date 2012 high resolution land-cover data we employed the online integrated meteorology-chemistry/aerosols Enviro-HIRLAM (Environment - High Resolution Limited Area Model) modeling system to simulate air temperature (at 2 meter height) fields for a selected period in July 2009. Employing research tools (such as METGRAF meteorological software and Geographical Information Systems) we then estimated the influence of different afforestation and urbanization scenarios with new forests being located after the Danish national afforestation plan, after proximity to the city center, after dominating wind characteristics, and urbanization taking place as densification of the existing conurbation. This study showed the difference in temperature up to 3.25°C, and the decrease in the spatial extent of temperature fields up to 68%, depending on the selected scenario. Performed simulations demonstrated

    Typhoid fever is a systemic illness which in high-income countries mainly affects travellers. The incidence is particularly high on the Indian subcontinent. Travellers who visit friends and relatives (VFR) have been shown to have a different risk profile than others. We wished to identify main characteristics for travellers infected with S. Typhi considering both clinical and laboratory findings in order to provide for faster and better diagnostics in the future. The outcome of treatment, especially concerning relapse, was evaluated as well. Retrospectively collected data from 19 adult cases of typhoid fever over a 5-year period at the Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre Denmark. The patients were young adults, presenting with symptoms within a month after travelling. 84% were returned from travelling in the Indian subcontinent. 17 out of 19 patients were VFR-travellers. The main symptoms were fever (100%), gastrointestinal symptoms (84%), headache (58%) and dry cough (26%). Laboratory findings showed elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH) in all cases and elevated alanine transaminase (ALAT) in 47% of cases. In primary cases 4 isolates were fully susceptible to ciprofloxacin, the remaining were intermediate susceptible. Relapse occurred in 37% of the cases and only in cases where the patient was infected by a strain with intermediate susceptibility. Better pre-travel counselling should be given to VFR-travellers. The main symptoms and laboratory findings confirm previous findings. The relapse rate was unexpected high and could be correlated to ciprofloxacin-resistance.

    Urban and transport planners worldwide have recently designed and implemented policies for increasing the number of cyclists. Although cycling is on the rise even in car-oriented cities and regions, the fear of being involved in a crash is still the main obstacle to further increases in cycling market shares. The current study proposes the first joint model of frequency and severity of cyclist-motorist collisions with the aim of unraveling the factors contributing to both the probability of being involved in a crash and, conditional on the crash occurrence, experiencing a severe injury outcome. A multivariate Poisson-lognormal model with correlated autoregressive priors was estimated on a sample of 5,349 cyclist-motorist crashes that occurred in the Copenhagen region between 2009 and 2013. The model considered the links of the road network in the region as the unit of observation, controlled for traffic exposure of nonmotorized and motorized transport modes, evaluated the effect of infrastructure and land use, and accounted for heterogeneity and spatial correlation across links. Results confirmed the existence of the phenomenon of safety in numbers and added to the narrative by emphasizing that the most severe crashes are the ones most benefiting from an increase in the number of cyclists. In addition, results argued that the construction of Copenhagen-style bicycle paths would significantly contribute to increasing safety, especially in suburban areas where the speed differential between cyclists and motorists is greater. Last, results illustrated a need for thinking about cycling safety in intersection design and reflecting on the importance of spatial and aspatial correlation both within and between injury categories. The findings from this study illustrated how encouraging cycling would increase safety in relation to the phenomenon of safety in numbers and how, in turn, increasing safety would convince more people to cycle. In addition, they suggested how the

    Myiasis is the infestation of tissues of live vertebrate animals and humans with dipterous larvae. In sub-Saharan Africa, Cordylobia anthropohaga and Cordylobia rodhaini are known to be responsible for cutaneous myiasis in animals and humans. Human cases of myiasis, purportedly acquired in Ghana but diagnosed in other countries, have been reported; however, published data on its occurrence in animals in Ghana is unavailable. This study assessed the prevalence of canine myiasis among owned dogs in the Greater Accra region (GAR) of Ghana. A cross-sectional study was conducted in the Greater Accra region of Ghana, selected for being the region with the highest estimated population density of owned dogs. Physical examination and demographic characteristics of the study dogs were assessed. Management of the dogs was assessed through a questionnaire administered to the dog owners. A total of 392 owned dogs were sampled. Twenty-nine (7.4%) had cutaneous myiasis caused by C. rodhaini. In addition, one (0.2%) of the dogs had intestinal myiasis, with Dermatobia hominis as the offending larvae. Among the breeds of dogs with myiasis, the mongrel was most affected, with 24 (82.8%) out of the 29 cases. The mongrels, majority of which (24; 82.8%) were males, were left to roam freely in the community. Results from this study demonstrate that C. rodhaini and D. hominis are important causes of myiasis in owned dogs in the GAR of Ghana. Dogs could play a role in the spread of myiasis to humans, with its attendant public health implications.

    The global oceans serve as the largest sustained natural sink for increasing atmospheric carbon dioxide (CO2) concentrations. As this CO2 is absorbed by seawater, it not only reacts causing a reduction in seawater pH (or acidification) but also decreases the carbonate mineral saturation state (Ω), which plays an important role in calcification for many marine organisms. Ocean acidification could affect some of the most fundamental biological and geochemical processes of the sea in coming decades. Observations obtained in situ from Volunteer Observing Ships and multiple geochemical surveys have been extended using satellite remote sensing and modeled environmental parameters to derive estimates of sea-surface alkalinity (AT) and carbon dioxide partial pressure (pCO2,sw). Pairing estimates of AT and pCO2,sw have permitted characterization of the changes in sea-surface Ω, which have transpired over the past decade throughout the Greater Caribbean Region as a consequence of ocean acidification. The results reveal considerable spatial and temporal variability throughout the region. Despite this variability, we observed a strong secular decrease in aragonite saturation state (Ωarg) at a rate of approximately -0.012 ± 0.001 Ωarg yr-1 (r2 = 0.97, P < 0.001).

    Emergence of serogroup B meningococci of clonal complex sequence type (ST) 41/44 can cause high levels of disease, as exemplified by a recent epidemic in New Zealand. Multiplication of annual incidence rates (3.1 cases/100,000 population) of meningococcal disease in a defined German region, the city of Aachen and 3 neighboring countries (Greater Aachen) prompted us to investigate and determine the source and nature of this outbreak. Using molecular typing and geographic mapping, we analyzed 1,143 strains belonging to ST41/44 complex, isolated from persons with invasive meningococcal disease over 6 years (2001-2006) from 2 German federal states (total population 26 million) and the Netherlands. A spatially slowly moving clone with multiple-locus variable-number tandem repeat analysis type 19, ST42, and antigenic profile B:P1.7-2,4:F1-5 was responsible for the outbreak. Bactericidal activity in serum samples from the New Zealand MeNZB vaccination campaign confirmed vaccine preventability. Because this globally distributed epidemic strain spreads slowly, vaccination efforts could possibly eliminate meningococcal disease in this area.

    Objectives: The purpose of the study was to assess the impact that funding from the National Network of Libraries of Medicine (NN/LM), Greater Midwest Region (GMR), has on member institutions' ability to conduct outreach on behalf of NN/LM. Methods: The study employed both content analysis and survey methodologies. The final reports from select GMR-funded outreach projects (n = 20) were analyzed based on a set of evaluation criteria. Project principal investigators (n = 13) were then surveyed using the same evaluation criteria. Results: Results indicated that outreach projects supported by GMR funding improved access to biomedical information for professionals and the general public. Barriers to conducting outreach projects included time constraints or commitments, staffing, scheduling and absenteeism, inadequate space, and issues associated with technology (e.g., hardware and software, Internet connectivity and firewall issues, and creation and use of new technologies). Conclusions: The majority of project principal investigators indicated that their attempts to conduct outreach were successful. Moreover, most noted that outreach had a positive impact on professionals as well as the general public. In general, it seems that negative outcomes, as with most barriers to conducting outreach, can be mitigated by more thorough planning. PMID:22022223

    During the last decades, the Particulate Matter (PM) pollution has become one of most challenging environmental problems worldwide. Along with their impact on global climate change and ecosystems, particles, especially for the smaller one, are indicated by numerous epidemiological studies to pose a great risk to human health with acute or long-term effects. Being located at the intersection of air masses circulating among three continents, the Mediterranean Basin is one of the areas heavily affected by aerosols with both natural and anthropogenic origin. Furthermore, the complex prevailing meteorology favours the aging of polluted air masses and induces high level of PM and photooxidant gases. In line with such scientific demands, the aim of the specific work is to elucidate the main characteristics of PM2.5 and PM1 nature (mass and chemical composition (Cl-, , SO , , K+, Mg2+, Ca2+, OC, EC)) of the Greater Athens Area (GAA) to elucidate the factors controlling the PM pollution and enable the policy makers to develop effective air quality remediation plans. Taking into consideration that PM measured at a specific site is the result of combined features and processes, at a local or a larger scale, as well as the air quality degradation by particulate matter over polluted areas which is often characterized by high levels of regional background aerosols, the main goal of this study is the identification and estimation of the local or regional contribution to the PM burden at GAA during different meteorological driven scenarios. Focusing on the changes in the prevailing atmospheric circulation patterns (mesoscale/synoptic wind regimes), a mass closure study of the available chemical species in conjunction with the observed PM mass is also attempted, in order to differentiate the relative contributions of the constituents. Special attention is also given to the high PM concentration (exceedances) days. The experimental campaign was held in parallel, during the period of

    Estimates of the prevalence of drug use in Denmark were, until 1999, based on the mortality multiplier method. This paper presents a study estimating the prevalence of problem opioid use in the Greater Copenhagen region using the capture-recapture method. Records from the prehospital mobile emergency care unit, The Copenhagen Prehospital Research Database, were searched with a particular focus on treatment of opioid overdose. In addition, data from The National Register of Drug Users in Treatment in Greater Copenhagen were analysed for the years 1997 and 1998. Four samples were used within the capture-recapture analysis, ie the Prehospital Research Database for 1997/1998 and the Register of Drug Users in Treatment for the same period. The estimates from the stratified capture-recapture analyses, when summed up, suggest that there is a hidden population of 4116 and thus a total population of 6992 opioid users in Greater Copenhagen (population approx 700,000). This corresponds to a rate of 10 per 1000 inhabitants aged 15-54 years. The 95% confidence attached to this estimate is 5787 to 10,885. The prevalence rate of 10 per 1000 inhabitants aged 15-54 years is comparable to figures found in similar cities in Europe. A previous study of Central Copenhagen calculated the rate to be 12.4 per 1000 inhabitants between 15 and 59 years. It seems reasonable that the estimate of prevalence of problem drug use in Greater Copenhagen is lower than the prevalence in Central Copenhagen, as the city area is more urbanised and has a slightly different demographic and socio-economic profile. About 75% of all opioid overdose incidents are assumed to occur in the central district of the city during the observed period.

  13. From Copenhagen to Neo-Copenhagen Interpretation

    Positive and negative features of the Copenhagen interpretation are discussed. As positive features can be mentioned its pragmatism and its awareness of the crucial role of measurement. However, the main part of the contribution is devoted to the negative features, to wit, its pragmatism (once again), its confounding of preparation and measurement, its classical account of measurement, its completeness claims, the ambiguity of its notion of correspondence, its confused notion of complementarity. It is demonstrated how confusions and paradoxes stemming from the negative features of the Copenhagen interpretation can be dealt with in an amended interpretation, to be referred to as `neo-Copenhagen interpretation', in which the role of the measuring instrument is taken seriously by recognizing the quantum mechanical character of its interaction with the microscopic object. The ensuing necessity of extending the notion of a quantum mechanical observable from the Hermitian operator of the standard formalism to the positive operator-valued measure of a generalized formalism yields a sound mathematical basis for a transition from the Copenhagen contextualistic-realist interpretation to the neo-Copenhagen empiricist one. Applications to the uncertainty relations and to the Bell inequalities are briefly discussed.

    The ore deposits described in this bulletin are distributed through a region of about 3,000 square miles surrounding the city of Helena, Mont. In general the surface of this region is mountainous, but it includes several large intermontane valleys. Large areas in the northern and eastern parts of the region sire underlain by sedimentary rocks of the Algonkian Belt series, and on the northeast and southwest the Belt rocks are overlain without any noticeable angular unconformity by Paleozoic and Mesozoic beds. Oligocene, Miocene, and possibly Pliocene sediments, composed chiefly of volcanic ash and land waste of local origin, occupy large areas in the intermontane valleys and lie unconformably upon Cretaceous and older rocks. A thin veneer of Pleistocene and Recent alluvium generally overspreads the Tertiary. In the extreme northern part of the region are large deposits of glacial drift that represent two stages of the Pleistocene. The principal igneous body of the region is the northern part of the early Tertiary or late Cretaceous Boulder batholitb of quartz monzonite. The main exposure of this body occupies an area of nearly 1,200 square miles and extends southward beyond the limits of the particular region considered. Smaller areas of similar rocks are clustered around this exposure. Most of the exposures probably represent bodies that are connected in depth to form a single mass. The late Cretaceous and older sedimentary rocks are involved in a series of northwestward-trending folds. Along the east side of the region overthrust faults related to the great Lewis overthrust of Glacier National Park cause Belt rocks to overlie rocks of Paleozoic and Mesozoic ages. Large normal faults occur near Marysville and faults of moderate displacement near Helena. The Tertiary beds are slightly deformed by folds and faults that are unrelated to the structure of the older rock. The geologic history of the region includes two contrasting periods, the earlier of which was

    2016-07-01

    In our quantum mechanics courses, measurement is usually taught in passing, as an ad-hoc procedure involving the ugly collapse of the wave function. No wonder we search for more satisfying alternatives to the Copenhagen interpretation. But this overlooks the fact that the approach fits very well with modern measurement theory with its notions of the conditioned state and quantum trajectory. In addition, what we know of as the Copenhagen interpretation is a later 1950s development and some of the earlier pioneers like Bohr did not talk of wave function collapse. In fact, if one takes these earlier ideas and mixes them with later insights of decoherence, a much more satisfying version of Copenhagen quantum mechanics emerges, one for which the collapse of the wave function is seen to be a harmless book keeping device. Along the way, we explain why chaotic systems lead to wave functions that spread out quickly on macroscopic scales implying that Schrödinger cat states are the norm rather than curiosities generated in physicists' laboratories. We then describe how the conditioned state of a quantum system depends crucially on how the system is monitored illustrating this with the example of a decaying atom monitored with a time of arrival photon detector, leading to Bohr's quantum jumps. On the other hand, other kinds of detection lead to much smoother behaviour, providing yet another example of complementarity. Finally we explain how classical behaviour emerges, including classical mechanics but also thermodynamics.

    Near surface geophysics are gaining widespread use in major infrastructure projects with respect to geotechnical and engineering applications. The development of data acquisition, processing tools and interpretation methods have optimized survey production, reduced logistics costs and increase results reliability of seismic surveys during the last decades. However, the use of geophysical methods under urban environments continues to face challenges due to multiple noise sources and obstacles inherent to cities. A seismic investigation was conducted in Copenhagen aiming to produce information needed for hydrological, geotechnical and groundwater modeling assessments related to the planned Cityringen underground metro project. The particular objectives were a) map variations in subsurface Quaternary and limestone properties b) to map for near surface structural features. The geological setting in the Copenhagen region is characterized by several interlaced layers of glacial till and meltwater sand deposits. These layers, which are found unevenly distributed throughout the city and present in varying thicknesses, overlie limestone of different generations. There are common occurrences of incised valley structures containing localized instances of weathered or fractured limestone. The surveys consisted of combined seismic reflection and refraction profiles accounting for approximately 13 km along sections of the projected metro line. The data acquisition was carried out using standard 192 channels arrays, receiver groups with 5 m spacing and a Vibroseis as a source at 5 m spacing. In order to improve the resolution of the data, 29 Walkaway-Vertical Seismic Profiles were performed at selected wells along the surface seismic lines. The refraction data was processed with travel-time tomography and the reflection data underwent standard interpretation. The refraction data inversion was performed twofold; a surface refraction alone and combined with the VSP data. Three

    Little is known about the effects of cigarette smoking on longitudinal brain morphological changes in the elderly. This study investigated the effects of a history of cigarette smoking on changes in regional brain volumes over 2 years in healthy, cognitively intact elderly individuals. We predicted that individuals with a history of cigarette smoking, compared with never smokers, demonstrate greater rate of atrophy over 2 years in regions that manifest morphological abnormalities in the early stages of Alzheimer's disease (AD), as well as in the extended brain reward/executive oversight system (BREOS), which is implicated in the development and maintenance of substance use disorders. Participants were healthy, cognitively normal elderly control subjects (75.9 ± 4.8 years of age) with any lifetime history of cigarette smoking (n = 68) or no history of smoking (n = 118). Data were obtained through the Alzheimer Disease Neuroimaging Initiative from 2005 to 2010. Participants completed four magnetic resonance scans over 2 years. A standardized protocol using high-resolution three-dimensional T1-weighted sequences at 1.5 T was used for structural imaging and regional brain volumetric analyses. Smokers demonstrated a significantly greater atrophy rate over 2 years than nonsmokers in multiple brain regions associated with the early stages of AD, as well as in the BREOS system. Groups did not differ on the rate of global cortical atrophy. A history of cigarette smoking in this healthy elderly cohort was associated with decreased structural integrity of multiple brain regions, which manifested as a greater rate of atrophy over 2 years in regions specifically affected by incipient AD as well as chronic substance abuse.

    Using a qualitative research methodology, twenty-four semi-structured interviews were conducted with women with induced abortion experiences at Korle Bu and Tema Hospitals in the Greater Accra Region, Ghana. Results suggest that these women tended not to have knowledge of contraceptive methods prior to the abortion, while others were informed but failed to use for a variety of reasons ranging from rumours of side effects to personal negative experiences with modem contraceptive methods. A few women also stated contraceptive failure as a reason for their unintended pregnancies that were later aborted. Peer and reproductive health education must be reinforced in communities in the Greater Accra Region to curb adolescents engaging in early sex and should challenge the existing rumours associated with contraception in Ghana. In addition, family planning services in terms of appropriate methods with no side effects must be made available to women in the reproductive ages.

    Existing interseismic models are not well-suited to simulate deformation within the network of finite, intersecting, nonplanar faults observed in the greater Los Angeles region. Instead of applying fault slip rates to a model a priori, we allow three-dimensional fault surfaces to interact and accumulate mechanically viable slip distributions and then use the deep nonseismogenic portion of slip to calculate interseismic deformation. We apply this approach to the Los Angeles region and find that the geologic timescale model results match well geologic slip rate data and the interseismic timescale model results match well the heterogeneous GPS velocity pattern in the Los Angeles region. Model results suggest that localized geodetic convergence in the San Gabriel basin can be achieved with slip on multiple active fault surfaces in the Los Angeles region including relatively fast slip on the Sierra Madre fault and slow slip on the Puente Hills thrusts, in agreement with geologic data. The ability of the three-dimensional model to reproduce well both geologic slip rates and interseismic geodetic velocity patterns suggests that current day contraction rates in the greater Los Angeles region are compatible with long-term geologic deformation rates and disputes suggestions of significant temporal variations in fault slip rates inferred from existing investigations.

    On November 8, ESO continued its series of presentations in memberstates with an event in Copenhagen. So far events have been organised in Belgium, Finland, Portugal, Sweden, Switzerland and the United Kingdom. The purpose of these presentations is to raise the awareness of ESO amongst decision-makers, academia and the media. Over time, the scope and specific focus of the national events have varied, considering the particular circumstances and the wishes of the national hosts, and accordingly, the presentation in Denmark was primarily oriented towards industry. The meeting was initiated by the Royal Danish Consulate General in Munich in conjunction with the Confederation of Danish Industries and the Ministry for Science, Technology and Innovation. Leading up to the meeting, several articles about ESO had appeared in the Danish press and the 2nd TV Channel featured a report on the ESO projects also in connection with the event.

Previous genetic surveys, mainly using Y-chromosome polymorphisms and/or mitochondrial DNA polymorphisms suggested a substantially reduced geneflow between populations belonging to these two phyla. These studies, however, have mainly focussed on populations residing far to the north and/or south of this mountain range, and have not been able to study geneflow patterns within the greater Himalayan region itself. We now report a detailed, linguistically informed, genetic survey of Tibeto-Burman and Indo-European speakers from the Himalayan countries Nepal and Bhutan based on autosomal microsatellite markers and compare these populations with surrounding regions. The genetic differentiation between populations within the Himalayas seems to be much higher than between populations in the neighbouring countries. We also observe a remarkable genetic differentiation between the Tibeto-Burman speaking populations on the one hand and Indo-European speaking populations on the other, suggesting that language and geography have played an equally large role in defining the genetic composition of present-day populations within the Himalayas.

    An integrated chemistry-climate model (RegCM4-CHEM) simulates present-day climate, ozone and tropospheric aerosols over Egypt with a focus on Greater Cairo (GC) region. The densley populated GC region is known for its severe air quality issues driven by high levels of anthropogenic pollution in conjuction with natural sources such as dust and agricultural burning events. We find that current global emission inventories underestimate key pollutants such as nitrogen oxides and anthropogenic aerosol species. In the GC region, average-ground-based NO2 observations of 40-60 ppb are substantially higher than modeled estimates (5-10 ppb), likely due to model grid resolution, improper boundary layer representation, and poor emissions inventories. Observed ozone concentrations range from 35 ppb (winter) to 80 ppb (summer). The model reproduces the seasonal cycle fairly well, but modeled summer ozone is understimated by approximately 15 ppb and exhibits little interannual variability. For aerosols, springtime dust events dominate the seasonal aerosol cycle. The chemistry-climate model captures the springtime peak aerosol optical depth (AOD) of 0.7-1 but is slightly greater than satellite-derived AOD. Observed AOD decreases in the summer and increases again in the fall due to agricultural burning events in the Nile Delta, yet the model underestimates this fall observed AOD peak, as standard emissions inventories underestimate this burning and the resulting aerosol emissions. Our comparison of modeled gas and particulate phase atmospheric chemistry in the GC region indicates that improved emissions inventories of mobile sources and other anthropogenic activities are needed to improve air quality simulations in this region.

    Cholera remains an important public health challenge globally. Several pandemics have occurred in different parts of the world and have been epidemiologically linked by different researchers to illustrate how the cases were spread and how they were related to index cases. Even though the risk factors associated with the 2014 cholera outbreak were investigated extensively, the link between index cases and the source of infection was not investigated to help break the transmission process. This study sought to show how the index cases from various districts of the Greater Accra Region may have been linked. We carried out a descriptive cross sectional study to investigate the epidemiological link of the 2014 cholera outbreak in the Greater Accra region of Ghana. An extensive review of all district records on cholera cases in the Greater Accra region was carried out. Index cases were identified with the help of line lists. Univariate analyses were expressed as frequency distributions, percentages, mean ± Standard Deviation, and rates (attack rates, case-fatality rates etc.) as appropriate. Maps were drawn using Arc GIS and Epi info software to describe the pattern of transmission. Up to 20,199 cholera cases were recorded. Sixty percent of the cases were between 20 and 40 years and about 58% (11,694) of the total cases were males. Almost 50% of the cases occurred in the Accra Metro district. Two-thirds of the index cases ate food prepared outside their home and had visited the Accra Metropolis. The 2014 cholera outbreak can be described as a propagated source outbreak linked to the Accra Metropolis. The link between index cases and the source of infection, if investigated earlier could have helped break the transmission process. Such investigations also inform decision-making about the appropriate interventions to be instituted to prevent subsequent outbreaks.

    Molecular phylogenetic studies of Haemodoraceae in the Greater Cape and Southwest Australian Floristic Region (SWAFR) using trnL, trnL-F and matK sequence data affirm the presence of old and young rapidly radiated lineages in both regions. Commencement of tribal and generic divergence in the subfamilies occured in the Eocene in the two regions, but subsequent patterns of radiation differ slightly. The hypothesis of rapid recent speciation in these regions from the late Pliocene as the major explanation for endemic species richness is still repeated by several contemporary authors despite increasing molecular phylogenetic evidence to the contrary. Our estimates of the age of lineages in Haemodoraceae show significant lineage turnover occurring over the last 15 million years, since the mid-Miocene, with divergence of the major clades beginning in the Eocene. The search for independent evidence to date speciation episodes reliably and investigation of molecular analyses across a broad spectrum of these clades must be pursued to advance ideas rigorously concerning origins of species richness. These regions continue to confound attempts to develop theory concerning origins of global species richness, with consequent implications for conservation biology.

    This work evaluates the first-order effect of land-use/land-cover change (LULCC) on the summer climate of one of the nation's most rapidly expanding metropolitan complexes, the Greater Phoenix, AZ, region. High-resolution-2-km grid spacing-Regional Atmospheric Modeling System (RAMS) simulations of three "wet" and three "dry" summers were carried out for two different land-cover reconstructions for the region: a circa 1992 representation based on satellite observations, and a hypothetical land-cover scenario where the anthropogenic landscape of irrigated agriculture and urban pixels was replaced with current semi-natural vegetation. Model output is evaluated with respect to observed air temperature, dew point, and precipitation. Our results suggest that development of extensive irrigated agriculture adjacent to the urban area has dampened any regional-mean warming due to urbanization. Consistent with previous observationally based work, LULCC produces a systematic increase in precipitation to the north and east of the city, though only under dry conditions. This is due to a change in background atmospheric stability resulting from the advection of both warmth from the urban core and moisture from the irrigated area. ?? 2008 Elsevier Ltd.

    We developed rangewide population and habitat models for Greater Sage-Grouse (Centrocercus urophasianus) that account for regional variation in habitat selection and relative densities of birds for use in conservation planning and risk assessments. We developed a probabilistic model of occupied breeding habitat by statistically linking habitat characteristics within 4 miles of an occupied lek using a nonlinear machine learning technique (Random Forests). Habitat characteristics used were quantified in GIS and represent standard abiotic and biotic variables related to sage-grouse biology. Statistical model fit was high (mean correctly classified = 82.0%, range = 75.4–88.0%) as were cross-validation statistics (mean = 80.9%, range = 75.1–85.8%). We also developed a spatially explicit model to quantify the relative density of breeding birds across each Greater Sage-Grouse management zone. The models demonstrate distinct clustering of relative abundance of sage-grouse populations across all management zones. On average, approximately half of the breeding population is predicted to be within 10% of the occupied range. We also found that 80% of sage-grouse populations were contained in 25–34% of the occupied range within each management zone. Our rangewide population and habitat models account for regional variation in habitat selection and the relative densities of birds, and thus, they can serve as a consistent and common currency to assess how sage-grouse habitat and populations overlap with conservation actions or threats over the entire sage-grouse range. We also quantified differences in functional habitat responses and disturbance thresholds across the Western Association of Fish and Wildlife Agencies (WAFWA) management zones using statistical relationships identified during habitat modeling. Even for a species as specialized as Greater Sage-Grouse, our results show that ecological context matters in both the strength of habitat selection (i

    Bovine tuberculosis (bTB) is a chronic, zoonotic, multi-species disease of cattle caused by Mycobacterium bovis. In developed countries, effective surveillance and enforcement of regulations on bTB control resulted in significant reduction of infections in cattle and hence, humans. However, in developing countries, weak surveillance systems affect accurate and timely reporting of bTB in humans and cattle. In Ghana, transhumance movement of cattle increases the risk of bTB importation and spread, however, the extent to which surveillance detects bTB is unknown. We therefore evaluated the bTB surveillance system in the Greater-Accra Region to determine its performance and assessed its attributes. We interviewed stakeholders, and reviewed bTB surveillance data for all ten districts in the region from 2006-2011 using the CDC Guidelines for Evaluation of public health surveillance systems. From 2006-2011, bTB was suspected in 284/244,576 (0.12%) cattle slaughtered, of which 7/284 (2.5%) were submitted for laboratory confirmation and all tested positive. Predictive value positive was 100%. There is no standard case definition which guides bTB detection. Fifty percent of carcasses slip through inspection, and confirmed cases are not traced back. There were 99/284 (34.9%) condemnations from suspected carcasses and 57/97 (58.8%) from positive reactors from screening. Ninety percent (9/10) of districts submitted reports late to the region whereas representativeness was 30%. Regional and district data were manually stored with no electronic backups. The region's cattle population is unknown. Although the bTB surveillance system is sensitive, it is under performing, and the possibility of bTB transmission from cattle to humans is high.

    Eighty-five stream sites in and near the six-county Greater Pittsburgh Region were sampled in mid-June 1971 in mid-October 1972. Data are reported for 89 sites because 4 substitute sites were sampled in the second period. Drainage areas of the basins sampled ranged from 4.1 to 19,5000 square miles (10.6 to 50,500 square kilometres). The chemical analyses included constituents of three general classes: (1) nutrients, (2) activity indicators, and (3) dominant anions. Modification of the natural chemical and physical characteristics of the surface waters by man's activities is evident in some of the data. However, the activities are so diverse in type and in areal extent that their influence in terms of cause and effect is often obscure. Nutrient concentrations were high enough to indicate potential problems at about a quarter of the sampling sites. Temperature, dissolved oxygen, and pH values indicated a generally favorable capacity for regeneration or recovery from degradation, although a number a streams east of the Allegheny and Monongahela Rivers are marginal or lacking in the capacity. Regionally, sulfate is the dominant ion and was observed in concentrations of 40 milligrams per litre or more at 90 percent of the sites. Bicarbonate exceeded 100 milligrams per litre at 22 sites. A moderate to high degree of mineralization, as indicated by conductance readings of more than 500 micromhos per cetrimetre at half of the sampling sites, is a characteristic of the region's surface waters.

    The western Greater Caucasus formed by the tectonic inversion of the western strand of the Greater Caucasus Basin, a Mesozoic rift that opened at the southern margin of Laurasia. Subsidence analysis indicates that the main phase of rifting occurred during the Aalenian to Bajocian synchronous with that in the eastern Alborz and, possibly, the South Caspian Basin. Secondary episodes of subsidence during the late Tithonian to Berriasian and Hauterivian to early Aptian are tentatively linked to initial rifting within the western, and possibly eastern, Black Sea and during the late Campanian to Danian to the opening of the eastern Black Sea. Initial uplift, subaerial exposure, and sediment derivation from the western Greater Caucasus occurred at the Eocene-Oligocene transition. Oligocene and younger sediments on the southern margin of the former basin were derived from the inverting basin and uplifted parts of its northern margin, indicating that the western Greater Caucasus Basin had closed by this time. A predominance of pollen representing a montane forest environment (dominated by Pinacean pollen) within these sediments suggests that the uplifting Caucasian hinterland had a paleoaltitude of around 2 km from early Oligocene time. The closure of the western Greater Caucasus Basin and significant uplift of the range at approximately 34 Ma is earlier than stated in many studies and needs to be incorporated into geodynamic models for the Arabia-Eurasia region.

    Activity concentration of the (222)Rn radionuclide was determined in drinking water samples from the Sothern Greater Poland region by liquid scintillation technique. The measured values ranged from 0.42 to 10.52 Bq/dm(3) with the geometric mean value of 1.92 Bq/dm(3). The calculated average annual effective doses from ingestion with water and inhalation of this radionuclide escaping from water were 1.15 and 11.8 μSv, respectively. Therefore, it should be underlined that, generally, it's not the ingestion of natural radionuclides with water but inhalation of the radon escaping from water which is a substantial part of the radiological hazard due to the presence of the natural radionuclides from the uranium and thorium series in the drinking water.

    Nowadays, people decide to have a baby by first analysing their financial situation. Tradition is no longer a factor which determines the decision whether or not to have a baby. A prognosis of the Polish Central Statistical Office (GUS) shows that the population of Poland will fall from 38 to 36 million by 2035. The aim of this study is to assess the procreation behaviour of women in Greater Poland Region. For the research purpose, 3,120 women of reproductive age were examined by using an author designed questionnaire and a synthetic Family Financial Standard Index. 74.6% of the respondents lived in an urban area, 25.4% of women come from a rural area. 49% of examined women did not want to have a bigger family, 45% would like to have another child. Analysis of the reasons why women did not want to have another baby revealed that predominance of the financial factor - 67%, living conditions - 18.4% and health- 13.2%. Only 11.9% of the women declared their high financial status, 4.8% of families received family allowance from the government; 88.4% of the examined families did not receive any social benefits. Bad housing situation was declared by 5% of the respondents, 26.7% of the interviewees lived with family members, i.e. parents or grandparents. Analysis of the data concerning religious bonds showed that 67.6% of women declared their indifference to religion. The economic factor was an important reason limiting procreation. The bad situation on the real estate market combined with an insufficient range of social welfare led to a decrease in the birth-rate in the Greater Poland region. The impact of religion on family planning was less important. The influence of the analysed socio-economic factors on family planning was similar in rural and urban areas.

    Background Housing has been a relatively neglected site for public health action. However, it remains a place where human beings spend the most part of their day. As a result, the quality of housing has consequences for human health. We investigate residential characteristics associated with self-rated occupant health in five neighbourhoods in the Greater Accra Region, Ghana. Methods A cross sectional study using a semi-structured questionnaire was conducted among 500 informed adults aged 18 years and above to investigate residential characteristics associated with self-rated occupant health in five neighbourhoods in the Greater Accra Region, Ghana. Correlates of occupant rated health were determined using Pearson chi-square test and binary logistic regression. Results Forty-two per cent of houses were rented, 44% required repair and 46% shared sanitation facilities. One in twenty occupants reported poor health. Gender, employment status, income, ventilation, house wall material, odours, stale air, privacy, shared facilities, hand washing facility, type of house and house repair status were associated with poor health in the bivariate analysis. Only two variables were independently associated with poor self-rated health: occupants who lacked privacy were eight times more likely to report poor self-rated health when compared to peers who did not lack privacy [OR = 8.16, 95% CI 2.86-23.26] and women were three times more likely than men to report poor health [OR = 2.98, 95% CI 1.06-8.35]. Conclusion The results provide further evidence of housing as a determinant of occupants’ health, and identify housing characteristics and living conditions as issues for public health action in Ghana.

    Recent studies evoke dispute whether the Himalayan metamorphic core - Greater Himalayan Crystalline Complex (GHC) - was exhumed as a lateral crustal flow or a critical taper wedge during the India-Asia collision. This contribution investigated the evolution of the GHC in the Nyalam region, south Tibet, with comprehensive studies on structural kinematics, metamorphic petrology and geochronology. The GHC in the Nyalam region can be divided into the lower and upper GHC. Phase equilibria modelling and conventional thermobarometric results show that peak temperature conditions are lower in the lower GHC (~660-700°C) and higher in the upper GHC (~740-780°C), whereas corresponding pressure conditions at peak-T decrease from ~9-13 kbar to ~4 kbar northward. Monazite, zircon and rutile U-Pb dating results reveal two distinct blocks within the GHC of the Nyalam region. The upper GHC underwent higher degree of partial melting (15-25%, via muscovite dehydration melting) that initiated at ~32 Ma, peaked at ~29 Ma to 25 Ma, possibly ended at ~20 Ma. The lower GHC underwent lower degree of melting (0-10%) that lasted from 19 to 16 Ma, which was produced mainly via H2O-saturated melting. At different times, both the upper and lower blocks underwent initial slow cooling (35 ± 8 and 10 ± 5°C/Myr, respectively) and subsequent rapid cooling (120 ± 40°C/Myr). The established timescale of metamorphism suggests that high-temperature metamorphism within the GHC lasted a long duration (~15 Myr), whereas duration of partial melting lasted for ~3 Myr in the lower GHC and lasted for 7-12 Myr in the upper GHC. The documented diachronous metamorphism and discontinuity of peak P-T conditions implies the presence of the Nyalam Thrust in the study area. This thrust is probably connected to the other thrusts in Nepal and Sikkim Himalaya, which extends over ~800 km and is named the "High Himalayan Thrust". Timing of activity along this thrust is at ~25-16 Ma, which is coeval with active

    Filipino Americans represent one of the largest and most diverse immigrant populations in the United States. It has been established that chronic diseases are a significant public health issue affecting this population. We conducted a health needs assessment of 200 Filipino Americans aged 18 years or older residing in the greater Philadelphia region. Study participants were recruited from eight Filipino community-based organizations in the region. Information about demographic and acculturative characteristics, health behaviors, self-reported chronic health conditions, and chronic disease perception were collected. Participants were older and highly acculturated. With regards to health behaviors, several did not meet dietary fruit and vegetables intake and physical activity guidelines. The top five health conditions were high blood pressure (67.5 %), high blood cholesterol (57.1 %), arthritis (28.9 %), diabetes (21.8 %), and cancer (14.7 %). Majority of participants perceived high blood pressure, high blood cholesterol, and diabetes to be a concern in their community, and had high awareness of the risk factors associated with these diseases. Reported rates of hypertension, high cholesterol, and diabetes suggest that lifestyle interventions targeting diet and physical activity, in addition to health education, are needed in this population.

    Although maternal and child mortality are on the decline in southeast Asia, there are still major disparities, and greater equity is key to achieve the Millennium Development Goals. We used comparable cross-national data sources to document mortality trends from 1990 to 2008 and to assess major causes of maternal and child deaths. We present inequalities in intervention coverage by two common measures of wealth quintiles and rural or urban status. Case studies of reduction in mortality in Thailand and Indonesia indicate the varying extents of success and point to some factors that accelerate progress. We developed a Lives Saved Tool analysis for the region and for country subgroups to estimate deaths averted by cause and intervention. We identified three major patterns of maternal and child mortality reduction: early, rapid downward trends (Brunei, Singapore, Malaysia, and Thailand); initially high declines (sustained by Vietnam but faltering in the Philippines and Indonesia); and high initial rates with a downward trend (Laos, Cambodia, and Myanmar). Economic development seems to provide an important context that should be coupled with broader health-system interventions. Increasing coverage and consideration of the health-system context is needed, and regional support from the Association of Southeast Asian Nations can provide increased policy support to achieve maternal, neonatal, and child health goals.

  2. Linking ecology to hydrology and geomorphology using river reach classification for the Greater Mekong Region

    2016-04-01

    Large-scale development projects, such as hydropower dams, in the Greater Mekong Region (GMR) are putting high pressure on freshwater resources. Environmental impact assessments are needed in the region to understand the possible impacts of these projects. These assessments often require biodiversity data that can be costly to acquire both in terms of time and money. It is often assumed that river or ecosystem classes, based on geo-physical characteristics, can be used as biodiversity proxies in large scale assessments to account for a lack of biodiversity data. However, there has been little research to compare the spatial distribution of river classes and fish species. It is unclear how well river classes are able to represent the distribution of fish and, more generally, biodiversity. To address this question, a set of two classifications were compared to a newly available dataset of fish species distribution in the GMR (Allen et al., 2012). The classifications were derived from two different methods to test which could potentially better represent fish assemblages. The first classification is derived using regional expert knowledge and the second using K-mean analysis. Both are using the same geophysical datasets. The two datasets were used in a Redundancy Analysis (RDA) to calculate which proportion of the variability in the fish species data can be explained by the river classes. The RDA resulted in R2 of 0.44 for the supervised classification and 0.41for the statistical classification, showing a moderate correlation between the datasets. Based on these results, using river classes as biodiversity proxy is deemed reasonable. However, some of the variability in the distribution of fish species cannot be related simply to geophysical factors. River classes may capture different elements such as unique habitats and associated, possibly unknown, endemic species that indices based only on biological data do not. Hence, river classes can be a good alternative and

    River classifications have been used in river health and ecological assessments as coarse proxies to represent aquatic biodiversity when comprehensive biological and/or species data is unavailable. Currently there are no river classifications or biological data available in a consistent format for the extent of the Greater Mekong Region (GMR; including the Irrawaddy, the Salween, the Chao Praya, the Mekong and the Red River basins). The current project proposes a new river habitat classification for the region, facilitated by the HydroSHEDS (HYDROlogical SHuttle Elevation Derivatives at multiple Scales) database at 500m pixel resolution. The classification project is based on the Global River Classification framework relying on the creation of multiple sub-classifications based on different disciplines. The resulting classes from the sub-classification are later combined into final classes to create a holistic river reach classification. For the GMR, a final habitat classification was created based on three sub-classifications: a hydrological sub-classification based only on discharge indices (river size and flow variability); a physio-climatic sub-classification based on large scale indices of climate and elevation (biomes, ecoregions and elevation); and a geomorphological sub-classification based on local morphology (presence of floodplains, reach gradient and sand transport). Key variables and thresholds were identified in collaboration with local experts to ensure that regional knowledge was included. The final classification is composed 54 unique final classes based on 3 sub-classifications with less than 15 classes each. The resulting classifications are driven by abiotic variables and do not include biological data, but they represent a state-of-the art product based on best available data (mostly global data). The most common river habitat type is the "dry broadleaf, low gradient, very small river". These classifications could be applied in a wide range of

In 1999 and 2000 a spring hunt of greater snow geese Anser caerulescens atlanticus occurred for the first time in North America since 1916, aimed at stopping population growth to protect natural habitats. 2. We evaluated the impact of this hunt on the staging movements of geese along a 600-km stretch of the St. Lawrence River in southern Quebec, Canada. 3. We tracked radio-tagged female geese in three contiguous regions of the staging area from the south-west to the north-east: Lake St Pierre, Upper Estuary and Lower Estuary, in spring 1997 (n = 37) and 1998 (n = 70) before the establishment of hunting, and in 1999 (n = 60) and 2000 (n = 59) during hunting. 4. We used multi-state capture-recapture models to estimate the movement probabilities of radio-tagged females among these regions. To assess disturbance level, we tracked geese during their feeding trips and estimated the probability of completing a foraging bout without being disturbed. 5. In the 2 years without hunting, migration was strongly unidirectional from the south-west to the north-east, with very low westward movement probabilities. Geese gradually moved from Lake St Pierre to Upper Estuary and then from Upper Estuary to Lower Estuary. 6. In contrast, during the 2 years with hunting westward movement was more than four times more likely than in preceding years. Most of these backward movements occurred shortly after the beginning of the hunt, indicating that geese moved back to regions where they had not previously experienced hunting. 7. Overall disturbance level increased in all regions in years with hunting relative to years without hunting. 8. Synthesis and applications. We conclude that spring hunting changed the stopover scheduling of this long-distance migrant and might further impact population dynamics by reducing prenuptial fattening. The spring hunt may also have increased crop

    Using velocity profiles from sites in Japan, California, Turkey, and Europe, we find that the time-averaged shear-wave velocity to 30 m (VS30), used as a proxy for site amplification in recent ground-motion prediction equations (GMPEs) and building codes, is strongly correlated with average velocities to depths less than 30 m (VSz, with z being the averaging depth). The correlations for sites in Japan (corresponding to the KiK-net network) show that VSz is systematically larger for a given VSz than for profiles from the other regions. The difference largely results from the placement of the KiK-net station locations on rock and rocklike sites, whereas stations in the other regions are generally placed in urban areas underlain by sediments. Using the KiK-net velocity profiles, we provide equations relating VS30 to VSz for z ranging from 5 to 29 m in 1-m increments. These equations (and those for California velocity profiles given in Boore, 2004b) can be used to estimate VS30 from VSz for sites in which velocity profiles do not extend to 30 m. The scatter of the residuals decreases with depth, but, even for an averaging depth of 5 m, a variation in logVS30 of ±1 standard deviation maps into less than a 20% uncertainty in ground motions given by recent GMPEs at short periods. The sensitivity of the ground motions to VS30 uncertainty is considerably larger at long periods (but is less than a factor of 1.2 for averaging depths greater than about 20 m). We also find that VS30 is correlated with VSz for z as great as 400 m for sites of the KiK-net network, providing some justification for using VS30 as a site-response variable for predicting ground motions at periods for which the wavelengths far exceed 30 m.

    The biomethane yield of various energy crops, selected among potential alternatives to maize in the Greater Region, was assessed. The biomass yield, the volatile solids (VS) content and the biochemical methane potential (BMP) were measured to calculate the biomethane yield per hectare of all plant species. For all species, the dry matter biomass yield and the VS content were the main factors that influence, respectively, the biomethane yield and the BMP. Both values were predicted with good accuracy by linear regressions using the biomass yield and the VS as independent variable. The perennial crop miscanthus appeared to be the most promising alternative to maize when harvested as green matter in autumn and ensiled. Miscanthus reached a biomethane yield of 5.5 ± 1 × 10(3)m(3)ha(-1) during the second year after the establishment, as compared to 5.3 ± 1 × 10(3)m(3)ha(-1) for maize under similar crop conditions.

    A great variety of hydrologic data are collected by many governmental agencies and other entities for diverse purposes. Some of the data are compiled and reported in readily available, widely known publications; some are not. Continuing requests for information on the locations of data collection sites and on the sources of data have suggested the need for a guide to that information. Presently active primary-data-collection sites have been located on a map of the Greater Pittsburgh region (Allegheny, Armstrong, Beaver, Butler, Washington, and Westmoreland Counties in southwestern Pennsylvania), and the sources of data--by publication or responsible agency-have been described. Secondary data collection sites have not been shown on the map, but several agencies involved in this activity have been listed. Hydrologic data are collected at the following numbers of identified sites under the auspices of federal, state, and interstate organizations: Precipitation or temperature .......... 39 Surface-water stage or discharge ...... 82 Surface-water quality ................. 69 Ground-water levels ................... 7

    This paper describes the HISTALP database, consisting of monthly homogenised records of temperature, pressure, precipitation, sunshine and cloudiness for the Greater Alpine Region (GAR, 4-19°E, 43-49°N, 0-3500m asl). The longest temperature and air pressure series extend back to 1760, precipitation to 1800, cloudiness to the 1840s and sunshine to the 1880s. A systematic QC procedure has been applied to the series and a high number of inhomogeneities (more than 2500) and outliers (more than 5000) have been detected and removed. The 557 HISTALP series are kept in different data modes: original and homogenised, gap-filled and outlier corrected station mode series, grid-1 series (anomaly fields at 1° × 1°, lat × long) and Coarse Resolution Subregional (CRS) mean series according to an EOF-based regionalisation. The leading climate variability features within the GAR are discussed through selected examples and a concluding linear trend analysis for 100, 50 and 25-year subperiods for the four horizontal and two altitudinal CRSs. Among the key findings of the trend analysis is the parallel centennial decrease/increase of both temperature and air pressure in the 19th/20th century. The 20th century increase (+1.2 °C/+ 1.1 hPa for annual GAR-means) evolved stepwise with a first peak near 1950 and the second increase (1.3 °C/0.6hPa per 25 years) starting in the 1970s. Centennial and decadal scale temperature trends were identical for all subregions. Air pressure, sunshine and cloudiness show significant differences between low versus high elevations. A long-term increase of the high-elevation series relative to the low-elevation series is given for sunshine and air pressure. Of special interest is the exceptional high correlation near 0.9 between the series on mean temperature and air pressure difference (high-minus low-elevation). This, further developed via some atmospheric statics and thermodynamics, allows the creation of barometric temperature series without use

    Simulations from 13 highly resolved regional climate models run within the Coordinated Downscaling Experiment initiative at 0.11° resolution with boundary forcings from five different Coupled Model Intercomparison Project Phase 5 global models are employed to derive future climate change signal for the Greater Alpine Region (GAR) and four smaller investigation areas. Evaluation statistics include mean temperature and precipitation, frequency of days with precipitation over 1 mm and over 15 mm, 90% quantile of the frequency distribution, and maximum number of consecutive dry days. The evaluation for the period from 1971 to 2000 indicates that the models reproduce spatial seasonal precipitation patterns. In general, the simulations underestimate the seasonal mean temperature and overestimate the mean precipitation values. In GAR the ensemble seasonal mean temperature bias ranges from -0.8 to -1.9°C. The bias in precipitation varies between +14.8% in summer and +41.6% in the winter season. Larger errors are found for other statistics and in the investigated regions. In general, no significant gains in the quality of reproduction of the observed precipitation and temperature statistics compared to previous experiments can be identified. The temperature calculations for 2071-2100 related to the period from 1971 to 2000 in the GAR area show ensemble mean increases in the seasonal mean 2 m temperature of 2.5°C in fall and winter, 2.4°C in summer, and 1.9°C in spring. In the same area, precipitation is simulated to increase up to 12.3% in winter and 5.7% in spring. Only minor changes of the ensemble mean are predicted with +2.3% in fall and -1.7% in summer.

  10. Strike-slip and extrusion tectonics of the Greater Caucasus-Kopetdagh region

    In the Paleogene-Early Miocene, the areas of the modern Greater Caucasus and Kopetdagh were occupied by marginal seas (parts of the Paratethys intracontinental sea) inheriting the Cretaceous back-arc basins. In the Early Miocene, a collisional compression of the seas began at the time when the Arabian plate detached from Africa to move northward. The compression proceeded in a good accordance with the Arabia movement that was manifested in a general synchroneity of the Late Alpine orogenies in the Caucasus and Kopetdagh with the rifting and spreading phases in the Aden Gulf and the Red Sea. The earliest orogeny was the Styrian one of the terminal Early Miocene. It corresponds to the initial stage of the rift opening and was mostly pronounced in the east, in Kopetdagh and East Iran, where a recent structure has been formed by the initial Middle Miocene. In the Greater Caucasus, the Styrian deformations occurred in its central part only (i.e., in front of the Arabian plate northern tip) where the main Caucasian thrusts and conjugate asymmetrical megaanticline of the Central Caucasus were formed. An essential feature of the earliest, Styrian, structure of the whole Caucasus-Kopetdagh region was a series of regional right-lateral strike-slip faults. In the Kopetdagh, the strike-slips have no submeridional but northwestern direction although they occurred in the northern continuation of the submeridional right-lateral strike-slip faults framing the Lut block. In the Caucasus, they became even sublatitudinal, in parallel with the North Anatolian fault, thus constituting a single domain with the latter. So, the right-lateral strike-slip faults of East Iran, Kopetdagh, and the Caucasus compose an extensive arc convex to the north and appeared probably as a result of the right-lateral shear caused by the known counterclockwise rotation of the Arabian lithospheric plate. The Middle Miocene was characterized by a tectonic pause both in the Red Sea-Aden rift system and in the

    Drought is a natural hazard impacting tremendously on human systems as latest events, like the summer 2015 drought in Central and Eastern Europe, show. However, extreme events are rare and only a few of the most recent ones are analyzed in detail concerning their emergence in space and time. With the study presented here, we aim to investigate spatiotemporal drought characteristics on a much larger sample of events covering the past 200+ years. The area of interest is the European Greater Alpine Region located at the intersection of three major climate divisions in Europe: Mediterranean climate as well as temperate oceanic and continental climate. We use gridded data of 3-month moving average precipitation sums which are transformed into percentile values for each grid point and each month individually to ensure comparability across regions and seasons. A threshold is applied to detect contiguous areas within the gridded fields below a given percentile threshold (20th percentile). Subsequently, all areas overlapping to a certain degree along time are treated as the same space-time object to form a meteorological drought event. Distinct attributes are derived for every event like duration, spatial extent, intensity, overall severity, season of peak intensity, temperature anomaly etc., which are analyzed in terms of their long-term temporal evolution, seasonality, spatial clustering and temperature characteristics. Our results indicate on one hand only minor changes in drought frequency and duration over the last 200 years, but on the other hand large variations in drought intensity and overall severity on multidecadal time scales. The time period from 1850-1880 shows highest drought intensities and also highest severities followed by a second peak from around 1930-1950. Furthermore, the top 10% of events in terms of their severity reveal a general shift in seasonality from winter/spring events in the late 19th century towards autumn events during the last decades of

    Parasites of wildlife inhabiting urbanised and peri-urban environments are of interest regarding wildlife population health, and also veterinary public health in the case of parasites that can also infect humans and domestic animals. This study aimed to: identify, and estimate the prevalence of, species of Eimeria parasitic in quenda (Isoodon obesulus) in the greater Perth region, Western Australia; 2) morphologically describe and genetically characterise a novel observed species of Eimeria as E. angustus; and 3) genetically characterise E. kanyana. Eimeria spp. prevalence was 76.1% (95% CI 64.9-84.5%), and four putative species of Eimeria were identified. Eimeria kanyana was identified infecting quenda for the first time, with a prevalence of 54.9% (43.4-66.0%). Eimeria quenda was less prevalent, at 7.0% (3.1-15.5%). The novel species E. angustus was present in 45.1% of sampled quenda (34.0-56.6%). A second novel morphotype of Eimeria was present in 2.8% of sampled quenda (0.9-9.7%). Mixed Eimeria spp. infections were present in 21/71 quenda (29.6%, 95% CI 20.2-41.1%). Molecular phylogenetic analyses of E. kanyana and E. angustus were conducted at the 18S rRNA and mitochondrial cytochrome oxidase loci. At both loci, two isolates identified as E. kanyana grouped in a phylogenetic clade with E. trichosuri. Five isolates identified as the novel E. angustus were most closely related to E. tropidura at the 18S locus. At the COI locus, no sequence data were available for E. tropidura; isolates of E. angustus grouped with E. sciurorum.

    INTRODUCTION: Based on recent analyses, the measures of short-term responsiveness of MRI derived cartilage morphometry may not be as large as earlier studies had suggested. We examined if by selecting regions of interest with denuded cartilage, if the remaining cartilage within this region of interest was susceptible to greater rates of cartilage loss. METHODS: Subjects included for this analysis are a subset of the approximately 4700 participants in the Osteoarthritis Initiative (OAI) Study. Bilateral radiographs and 3T MRI (Siemens Trio) of the knees and clinical data are obtained at baseline and annually in all participants.150 subjects from the OAI Progression subcohort all of whom had both frequent symptoms and, in the same knee, radiographic osteoarthritis (ROA defined as definite tibio-femoral osteophytes on x-ray) based on a screening reading done at the OAI clinics. One knee from each subject was selected for analysis. Using sagittal 3D DESSwe MR images from the baseline and 12 follow-up month visit, a segmentation algorithm was applied to the cartilage plates of the index knee to compute the cartilage volume, normalized cartilage volume (Volume normalized to bone surface interface area), and percent denuded area (Total Cartilage Bone Interface area denuded of cartilage). Summary statistics of the changes (absolute and percentage) from baseline at one year and the standardized response mean (SRM), i.e. mean change divided by the standard deviation of that change were calculated. Analyses are stratified into three groups according to baseline assessment of denuded area: those with no denuded area in the region of interest at baseline, and then 2 groups (intermediate denuded area (≤median) and severe (> median) denuded area) of equal sample size. RESULTS: On average the subjects were 60.9 years of age and obese with a mean BMI of 30.3 kg/m2. For the combined central medial femur and tibia the mean volume change for the whole sample was −48.2 (SD 159

    The distribution of spatial genetic variation across a region can shape evolutionary dynamics and impact population persistence. Local population dynamics and among-population dispersal rates are strong drivers of this spatial genetic variation, yet for many species we lack a clear understanding of how these population processes interact in space to shape within-species genetic variation. Here, we used extensive genetic and demographic data from 10 subpopulations of greater sage-grouse to parameterize a simulated approximate Bayesian computation (ABC) model and (i) test for regional differences in population density and dispersal rates for greater sage-grouse subpopulations in Wyoming, and (ii) quantify how these differences impact subpopulation regional influence on genetic variation. We found a close match between observed and simulated data under our parameterized model and strong variation in density and dispersal rates across Wyoming. Sensitivity analyses suggested that changes in dispersal (via landscape resistance) had a greater influence on regional differentiation, whereas changes in density had a greater influence on mean diversity across all subpopulations. Local subpopulations, however, varied in their regional influence on genetic variation. Decreases in the size and dispersal rates of central populations with low overall and net immigration (i.e. population sources) had the greatest negative impact on genetic variation. Overall, our results provide insight into the interactions among demography, dispersal and genetic variation and highlight the potential of ABC to disentangle the complexity of regional population dynamics and project the genetic impact of changing conditions.

    Left ventricular (LV) hypertrophy is associated with cardiovascular complications and the geometry is important for prognosis. In some cardiovascular diseases, myocardial hypertrophy or dilation occurs regionally without modifying the global size of the heart. It is therefore relevant to determine regional normal reference values of the left ventricle. The aim of this study was to derive reference values of regional LV myocardial thickness (LVMT) and mass (LVMM) from a healthy study group of the general population using cardiac computed tomography angiography (CCTA). We wanted to introduce LV myocardial distribution (LVMD) as a measure of regional variation of the LVMT. Moreover, we wanted to determine whether these parameters varied between men and women. We studied 568 (181 men; 32%) adults, free of cardiovascular disease and risk factors, who underwent 320-detector CCTA. Mean age was 55 (range 40-84) years. Regional LVMT and LVMM were measured, according to the American Heart Association's 17 segment model, using semi-automatic software. Mean LVMT were 6.6 mm for men and 5.4 mm for women (p < 0.001). The normal LV was thickest in the basal septum (segment 3; men = 8.3 mm; women = 7.2 mm) and thinnest in the mid-ventricular anterior wall (segment 7; men = 5.6 mm; women = 4.5 mm) for both men and women. However, the regional LVMD differed between men and women, with the LV being most heterogenic in women. The normal human LV is morphologically heterogenic, and showed same overall pattern but different regional distribution for men and women. This study introduces LVMD and provides gender specific reference values for regional LVMT, LVMM, and LVMD.

  17. Is human Achilles tendon deformation greater in regions where cross-sectional area is smaller?

    PubMed

    2017-05-01

    The Achilles is a long tendon varying in cross-sectional area (CSA) considerably along its length. For the same force, a smaller CSA would experience higher tendon stress and we hypothesised that these areas would therefore undergo larger transverse deformations. A novel magnetic resonance imaging-based approach was implemented to quantify changes in tendon CSA from rest along the length of the Achilles tendon under load conditions corresponding to 10%, 20% and 30% of isometric plantar flexor maximum voluntary contraction (MVC). Reductions in tendon CSA occurring during contraction from the resting condition were assumed to be proportional to the longitudinal elongations within those regions (Poisson's ratio). Rather than tendon regions of smallest CSA undergoing the greatest deformations, the outcome was region specific, with the proximal (gastrocnemius) tendon portion showing larger transverse deformations upon loading compared with the distal portion of the Achilles (P<0.01). Transverse tendon deformation only occurred in selected regions of the distal Achilles tendon at 20% and 30% of MVC, but in contrast occurred throughout the proximal portion of the Achilles at all contraction levels (10%, 20% and 30% of MVC; P<0.01). Calculations showed that force on the proximal tendon portion was ∼60% lower, stress ∼70% lower, stiffness ∼30% lower and Poisson's ratio 6-fold higher compared with those for the distal portion of the Achilles tendon. These marked regional differences in mechanical properties may allow the proximal portion to function as a mechanical buffer to protect the stiffer, more highly stressed, distal portion of the Achilles tendon from injury. © 2017.

    The levels of trihalomethanes (THMs)--the main species of by-product from water chlorination--were monitored in the distribution systems of the five major drinking water utilities of the greater area of Québec City in order to investigate and model their occurrence on a spatial and seasonal basis. Data for THMs and other water quality and operational parameters associated with their formation were generated through a 16 month sampling program involving several sites representing variable water residence times, from the plant to the system extremity. The results demonstrate that the differences in measured THM levels between the five utilities are mainly due to the variable quality of raw waters, the type of water treatment process being used and the type and levels of applied disinfectant. Depending on the utility, average THM levels were from 1.3 to 2.5 times higher in the system extremities than in the water leaving the treatment plant. Also, average levels of THMs measured in summer at the distribution system extremities were, depending on the utility, from 2.5 to 5 times higher than the average levels measured in winter. The seasonal differences were found to be significantly greater than those observed by others in water utilities in the United States and Europe and are explained in large part by the considerable changes, over the year, in the quality and temperature of surface waters in Southern Quebec. For the live utilities under study, multivariate regression models were developed in order to predict spatial and seasonal variations of THMs. Both residual chlorine demand and temperature were found to be better, statistically, as predictors for THM occurrence. The usefulness of the developed models for routine and long term water quality management, as well as for assessment of human exposure to THMs, are also discussed.

    Two independent analyses of the daily maximum 8 h average ozone concentrations measured during the high ozone season (May through October) at Continuous Ambient Monitoring Stations are used to quantify the regional background ozone transported into the Houston-Galveston-Brazoria (HGB) area. The dependence on wind direction is examined, and long-term trends are determined using measurements made between 1998 and 2012. Both analyses show that the regional background ozone has declined during periods of continental outflow: i.e., the conditions associated with most high ozone episodes in HGB. The changes in regional background ozone found for northeasterly and southeasterly flow are -0.50 ± 0.54 and -0.79 ± 0.65 (95% confidence limit) ppbv yr(-1), respectively, which correspond to decreases of ∼7-11 ppbv between 1998 and 2012. This finding is consistent with the summertime downward trend of -0.45 ppbv yr(-1) (range of sites: -0.87 to +0.07 ppbv yr(-1)) for ozone in the eastern U.S. between 1990 and 2010 reported by Cooper et al. and shows that changing background concentrations are at least partially responsible for the decreased surface ozone in the HGB area over the past decade. Baseline ozone concentrations in air flowing into Texas from the Gulf of Mexico have not changed significantly over this period.

  1. Martian Impact Craters Modified by Post-impact Processes in the Greater Hellas Region

    The appearance of the impact craters on the Martian surface depends on numerous factors beginning from the size, mass, velocity, type, and impact angle of the approaching projectile [1]. These all have affected on the impact energy delivered into the surface. The bedrock properties have then resulted in additional effects. Besides some major phenomena (Pre-existing faults and fractures, permafrost-saturated layers) there may have been numerous more delicate variations due to local projectile-bedrock combinations. Various post-impact deformation processes may then have changed the appearance of an impact crater to the extent that it is difficult to identify any original crater characteristics in great details. The changes in the crater appearances can, however, be looked in a positive way to provide crucial information on the local surface geology, bedrock properties and, more generally, on the whole post-impact geological evolution of the area studied [2,3,4]. We have characterized and studied the various crater deformation types found from within the large Hellas area. As it is one of the possible previous water body areas on Mars and lies also close to the southern permafrost and the south-pole environment, many craters locating within the greater Hellas Basin area have undergone substantial fluvial processes. Still, many of their surviving geologic features are enough well preserved. The good state of preservation is due partly to the relative youth of the craters and/or partly to Martian relative dryness. The absence of permanent water cover limits the weathering of surface materials, while it optimizes the site's exposure for geologic surveys by remote-sensing. This allows to estimate that the effects related to permafrost, water, erosion and sedimentation have been far more important within the greater Hellas area than what was earlier assumed using the previous data sets which have had defects either in resolution or in areal coverage.

    Moderate resolution satellite imagery traditionally has been thought to be inadequate for mapping vegetation at the species level. This has made comprehensive mapping of regional distributions of sensitive species, such as whitebark pine, either impractical or extremely time consuming. We sought to determine whether using a combination of moderate resolution satellite imagery (Landsat Enhanced Thematic Mapper Plus), extensive stand data collected by land management agencies for other purposes, and modern statistical classification techniques (boosted classification trees) could result in successful mapping of whitebark pine. Overall classification accuracies exceeded 90%, with similar individual class accuracies. Accuracies on a localized basis varied based on elevation. Accuracies also varied among administrative units, although we were not able to determine whether these differences related to inherent spatial variations or differences in the quality of available reference data.

    Tissues of greater scaup (Aythya marila mariloides) and components of their habitat (sediment, plankton, macroalgae, and invertebrates) were collected for heavy metal analysis in the winter of 1996-97 from US Department of the Interior wildlife refuges in the Long Island region. Geographic and temporal relationships between the concentration of nine metals in tissue and in habitat components were examined. In greater scaup tissues and habitat components, concentrations of As and Se were highest in Branford, Connecticut; Pb values were greatest in Oyster Bay, New York; and Hg concentrations were largest in Sandy Hook, New Jersey. Over the course of the winter, the concentration of Hg in liver increased, and concentrations of Cd, Cr, Cu, Hg, Pb, Se, and Zn in kidney decreased. Based on several criteria derived from geographic and temporal trends, metals were ranked using the apparent biomonitoring efficacy of greater scaup (As = Cr > Cu = Pb = Zn = Hg > Se = Cd > Ni). Although the seasonal migration and daily mobility of greater scaup are drawbacks to using this species as a sentinel for metal pollution, it was possible to demonstrate a relationship between geographic and temporal patterns of metals in habitat and greater scaup tissue. However, most metal concentrations in tissue were below thresholds known to adversely affect health of waterfowl.

    Morphological characterization of valley networks in three exposures of ancient cratered highlands (Nhc1) in the greater Meridiani Planum region yields insight into the Martian aqueous history. From our mapping, key regional differences are apparent in fine-scale valley network attributes including morphologic type, planimetric form, density, and links to candidate paleolakes. This information, combined with crater retention age (inferred exposure age), provides new details on the relative timing and nature of aqueous processes in the region. Newly identified pitted-type valley networks have morphological similarity to terrestrial pitted landforms in an evaporite setting. We interpret the pitted valley networks to reflect late-stage groundwater processes concentrated along the former fluvial conduits. Evidence from this study indicates that localized reactivation of valley networks occurred during or after exhumation of eastern Nhc1 unit.

  8. Basement geology and tectonic development of the greater New Zealand region: an interpretation from regional magnetic data

    The basement geology of New Zealand is composed of early Palaeozoic terranes of the Western Province, that are separated from late Palaeozoic-Mesozoic Eastern Province terranes by a suite of Carboniferous-Cretaceous arc-related igneous rocks (Median Tectonic Zone, MTZ). The Stokes Magnetic Anomaly System (SMAS) is associated with MTZ rocks and volcanogenic basement terranes of the Eastern Province. Offshore, it can be traced north along the northern margin of the New Caledonia Basin, and correlative Eastern Province rocks are found in New Caledonia. It can also be traced south across the Great South Basin, until a significant ENE-trending tectonic boundary is encountered on the central Campbell Plateau. This boundary is defined by linear gravity and magnetic anomalies (Campbell Magnetic Anomaly System, CMAS), and narrow fault-bounded sedimentary basins. If the sources of CMAS anomalies are correlative with those of the SMAS, then magnetic data require a ˜400 km dextral offset of basement rocks by faults along the northern margin of the CMAS prior to 80 Ma. The geometry of correlative Western Province and MTZ rocks in Marie Byrd Land supports the hypothesis that CMAS anomalies are sourced by MTZ-correlative rocks. A NNE-trending boundary on the central Challenger Plateau marks a change from high amplitude magnetic anomalies to weakly magnetic basement, and appears to represent a fundamental change in crustal character. The western Challenger Plateau and Lord Howe Rise (south of 30°S) are characterised by high amplitude magnetic and gravity anomalies with a NW-trending fabric, but the source of magnetic anomalies is unresolved. The magnetic character, combined with Cretaceous reconstruction, supports basement rock correlations with the east Lachlan Fold Belt or New England Fold Belt in Australia, rather than Western Province rocks in New Zealand. The magnetic signature of marginal ocean crust around New Zealand also offers clues into the region's tectonic history

    The Metro Boston region, an area whose civic leaders have been at the forefront of climate resilience initiatives in recent years, is finalizing a flood vulnerability assessment of food distribution center sites located north of Boston, with the support of the University of Massachusetts Boston and the American Geophysical Union's Thriving Earth Exchange program. The community-scientist collaboration emerged because of the need for more local analyses of the area to inform climate resiliency policy and planning actions for the region. A significant amount of the metro region's food supply passes through two major distribution centers in the cities of Everett and Chelsea, just north of the Mystic River. The Metropolitan Area Planning Council (MAPC), on behalf of the Metro Boston Climate Preparedness Taskforce, is working with Chris Watson and Ellen Douglas of UMass Boston to build on existing analyses of the region's food system and climate vulnerabilities and to develop a report identifying flood risk exposure to the sites. The analysis brings in dynamic modeling techniques that incorporate storm surge and sea level rise projections under different climate scenarios, and aims to align methodologies with those of other regional analyses, such as Climate Ready Boston and the City of Cambridge's Vulnerability Assessment. The study is helping to inform MAPC's and the Metro Boston Climate Preparedness Taskforce's understanding of this critical food distribution infrastructure, illustrate the larger regional implications of climate impacts on food distribution in the Greater Boston area, and guide the development of site-specific strategies for addressing identified vulnerabilities.

    It is important to understand the vulnerability of the water management system in south Florida and to determine the resilience and robustness of greater Everglades restoration plans under future climate change. The current climate models, at both global and regional scales, are not ready to deliver specific climatic datasets for water resources investigations involving future plans and therefore a scenario based approach was adopted for this first study in restoration planning. We focused on the general implications of potential changes in future temperature and associated changes in evapotranspiration, precipitation, and sea levels at the regional boundary. From these, we developed a set of six climate and sea level scenarios, used them to simulate the hydrologic response of the greater Everglades region including agricultural, urban, and natural areas, and compared the results to those from a base run of current conditions. The scenarios included a 1.5 °C increase in temperature, ±10 % change in precipitation, and a 0.46 m (1.5 feet) increase in sea level for the 50-year planning horizon. The results suggested that, depending on the rainfall and temperature scenario, there would be significant changes in water budgets, ecosystem performance, and in water supply demands met. The increased sea level scenarios also show that the ground water levels would increase significantly with associated implications for flood protection in the urbanized areas of southeastern Florida.

    Copenhagen Airport Cohort 1990-2012 presents a unique data source for studies of health effects of occupational exposure to air pollution (ultrafine particles) and manual baggage handling among airport employees. We describe the extent of information in the cohort and in the follow-up based on data linkage to the comprehensive Danish nationwide health registers. In the cohort, all information is linked to the personal identification number that also is used in Denmark Statistics demographic and socioeconomic databases and in the nationwide health registers. The cohort covers 69 175 men in unskilled positions. The exposed cohort includes men in unskilled jobs employed at Copenhagen Airport in the period 1990-2012 either as baggage handlers or in other outdoor work. The reference cohort includes men in unskilled jobs working in the greater Copenhagen area. The cohort includes environmental Global Positioning System (GPS) measurements in Copenhagen Airport, information on job function/task for each calendar year of employment between 1990 and 2012, exposure to air pollution at residence, average weight of baggage lifted per day and lifestyle. By linkage to registers, we retrieved socioeconomic and demographic data and data on healthcare contacts, drug subscriptions, incident cancer and mortality. The size of the cohort and the completeness of the register-based follow-up allow a more accurate assessment of the possible health risks of occupational exposure to ultrafine particles and manual baggage handling at airports than in previous studies. We plan to follow the cohort for the incidence of ischaemic heart diseases, cerebrovascular disease, lung and bladder cancer, asthma and chronic obstructive pulmonary disease, and further for associations between heavy manual baggage handling and musculoskeletal disorders. number 2012-41-0199.

    This paper is part 1 of a two-part study that evaluates the climatic effects of recent landscape change for one of the nation's most rapidly expanding metropolitan complexes, the Greater Phoenix, Arizona, region. The region's landscape evolution over an approximate 30-year period since the early 1970s is documented on the basis of analyses of Landsat images and land use/land cover (LULC) data sets derived from aerial photography (1973) and Landsat (1992 and 2001). High-resolution, Regional Atmospheric Modeling System (RAMS), simulations (2-km grid spacing) are used in conjunction with consistently defined land cover data sets and associated biophysical parameters for the circa 1973, circa 1992, and circa 2001 time periods to quantify the impacts of intensive land use changes on the July surface temperatures and the surface radiation and energy budgets for the Greater Phoenix region. The main findings are as follows: since the early 1970s the region's landscape has been altered by a significant increase in urban/suburban land area, primarily at the expense of decreasing plots of irrigated agriculture and secondarily by the conversion of seminatural shrubland. Mean regional temperatures for the circa 2001 landscape were 0.12??C warmer than the circa 1973 landscape, with maximum temperature differences, located over regions of greatest urbanization, in excess of 1??C. The significant reduction in irrigated agriculture, for the circa 2001 relative to the circa 1973 landscape, resulted in dew point temperature decreases in excess of 1??C. The effect of distinct land use conversion themes (e.g., conversion from irrigated agriculture to urban land) was also examined to evaluate how the most important conversion themes have each contributed to the region's changing climate. The two urbanization themes studied (from an initial landscape of irrigated agriculture and seminatural shrubland) have the greatest positive effect on near-surface temperature, increasing maximum daily

    Observed intensification of precipitation extremes, responsible for extensive societal impacts, are widely attributed to anthropogenic sources, which may include indirect effects of agricultural irrigation. However quantifying the effects of irrigation on far-downstream climate remains a challenge. We use three paired Community Earth System Model simulations to assess mechanisms of irrigation-induced precipitation trends and extremes in the conterminous US and the effect on the terrestrial carbon sink. Results suggest precipitation enhancement in the central US reduced drought conditions and increased regional carbon uptake, while further downstream, the heaviest precipitation events were more frequent and intense. Specifically, moisture advection from irrigation in the western U.S. and recycling of enhanced local convective precipitation produced very-heavy storm events that were 11% more intense and occurred 23% more frequently in the densely populated greater New York City region.

    The Demonstration of Decision Support Tools for Sustainable Development project integrated the Bechtel/Nexant Industrial Materials Exchange Planner and the Idaho National Engineering and Environmental Laboratory System Dynamic models, demonstrating their capabilities on alternative fuel applications in the Greater Yellowstone-Teton Park system. The combined model, called the Dynamic Industrial Material Exchange, was used on selected test cases in the Greater Yellow Teton Parks region to evaluate economic, environmental, and social implications of alternative fuel applications, and identifying primary and secondary industries. The test cases included looking at compressed natural gas applications in Teton National Park and Jackson, Wyoming, and studying ethanol use in Yellowstone National Park and gateway cities in Montana. With further development, the system could be used to assist decision-makers (local government, planners, vehicle purchasers, and fuel suppliers) in selecting alternative fuels, vehicles, and developing AF infrastructures. The system could become a regional AF market assessment tool that could help decision-makers understand the behavior of the AF market and conditions in which the market would grow. Based on this high level market assessment, investors and decision-makers would become more knowledgeable of the AF market opportunity before developing detailed plans and preparing financial analysis.

    Highly pathogenic avian influenza H5N1 has been a global concern for almost 10 years since its epidemic emergence in South-east Asia in 2003/2004. Despite large investment of resources into the region, the infection has not been eradicated and continues to result in outbreaks in poultry and a small number of human fatalities. This review synthesizes the knowledge base generated by a vast number of research activities conducted in the region and beyond, and adopts an interdisciplinary perspective consistent with the one health paradigm towards analysing the problem and formulating possible policy solutions. A key outcome of the work has been the need to integrate socio-economic and anthropological dimensions with any disease control and prevention activities traditionally informed by primarily epidemiological, virological and pathological attributes of the infection in poultry and wild waterbirds. Recommendations at a broad conceptual level are presented that acknowledge the diversity in the region with respect to livestock production, as well as the changing nature of the risk landscape as a consequence of the rapid economic development which some of the countries in the Greater Mekong sub-region are currently undergoing, as well as their strong trade links with China as the major economic power in East Asia.

    The most recent release of the MODIS (Moderate resolution Imaging Spectroradiometer) aerosol product is Collection 6 which replaced Collection 5.1. The core parameter of the MODIS aerosol product is the aerosol optical depth at 550 nm (AOD550). AOD550 retrievals from the two MODIS sensors aboard the EOS Terra and Aqua satellites have been extensively used the last fifteen years to examine the sources, the variability of aerosols and the effect they exert on air quality and climate. Collection 6 is currently used in studies focusing on the greater Mediterranean region; however, an evaluation of the Collection 6 AOD550 dataset against ground-based observations and an assessment of its differences and similarities to the previous widely used Collection 5.1 is missing. In this work, we present a first comparison of the MODIS/Terra and Aqua Collection 6 and Collection 5.1 AOD550 data for the greater Mediterranean region (Georgoulias et al., 2016). It is shown here that Collection 6 AODs are either higher or lower than Collection 5.1 AODs over different continental areas. On the contrary, over the sea, Collection 6 AODs are higher almost everywhere (11% for MODIS/Terra and 8% for MODIS/Aqua). Collection 6 generally retrieves higher AODs than Collection 5.1, especially for MODIS/Terra. Collection 6 and 5.1 AOD550 data were evaluated against sunphotometric observations from 23 AERONET stations in the region. It is shown that Collection 6 exhibits a better agreement with the ground-based data than Collection 5.1. Our trend analysis shows that the Collection 6 AOD550 data exhibit a statistically significant negative trend of ˜-0.001/year (˜-0.5%/year) for MODIS/Terra and ˜-0.002/year (˜-1.0%/year) for MODIS/Aqua. Collection 6 AOD550 trends are largely reduced compared to Collection 5.1 trends by ˜0.003/year for MODIS/Terra. On the contrary, for MODIS/Aqua the trends have not changed significantly (only by ˜0.0003/year). *Georgoulias, A.K., Alexandri, G., Kourtidis, K

  19. On the influence of multi-decadal North Atlantic climate variations on drought occurrence in the European Greater Alpine Region

    2017-04-01

    The development of drought is characterized by an evolving precipitation deficit taking place on different spatial and temporal scales. As recent studies show, meteorological drought characteristics, like intensity, seasonality and severity, exhibit multi-decadal changes. Internal variations of the climate system and the associated changes of dominant weather regimes are therefore considered the main driver of these drought features. In this study we analyze the connection between drought characteristics and large scale atmospheric and oceanic modes particularly those of the North Atlantic which are heavily influencing European climate. We use the dataset of Haslinger and Blöschl (2017) which consists of a collection of meteorological drought events occurring in the European Greater Alpine Region (GAR) over the past 210 years. Every event is determined by an extent in space and time and certain attributes as duration, intensity, temperature anomaly, region of most impact etc. In addition the monthly time series of the North Atlantic Oscillation Index (NAO) and the Atlantic Multidecadal Oscillation Index (AMO) are used. Preliminary results show that late winter and spring droughts are associated with a positive phase of the NAO, which is particularly the case for the more continentally and Mediterranean influenced areas of the GAR. A regression analysis of the 30-year running mean NAO Index and drought intensities reveal a strong connection (r2 = 0.7) from 1820 until 1960. However, afterwards the correlation drops significantly (r2 = 0.3). This abrupt change might indicate a general regime shift considering long-term precipitation characteristics in the GAR.

  20. The Distribution of Fault Slip Rates and Oblique Slip Patterns in the Greater Los Angeles, CA Region

    NASA Astrophysics Data System (ADS)

    Harper, H.; Marshall, S. T.

    2014-12-01

    The Los Angeles basin is host to a complex network of active strike-slip, reverse, and oblique slip faults. Because of the large metropolitan region occupying the basin, even moderately large earthquakes (M6+) pose a significant natural hazard. Since geologic estimates have not fully characterized the distribution of active fault slip rates in the region, we use a mechanical model driven by geodetically-measured shortening rates to calculate the full three-dimensional fault slip rate distributions in the region. The modeled nonplanar fault geometries are relatively well-constrained, and use data from the SCEC community fault model. Area-weighted average fault slip rates predicted by the model match previously measured geologic slip rates in most cases; however, some geologic measurements were made in locations where the slip rate is non-characteristic of the fault (e.g. near a fault tip) and the geologic slip rate estimate disagrees with the model-predicted average slip rate. The largest discrepancy between the model predictions and geologic estimates occurs on the Sierra Madre fault, which has a model-predicted slip rate approximately 2 mm/yr greater than the geologic estimates. An advantage of the model is that it can predict the full three-dimensional mechanically compatible slip distribution along all modeled faults. The fault surface slip distribution maps show complex oblique slip patterns that arise due to the nonplanar geometries and mechanical interactions between intersecting and neighboring faults. For example, the Hollywood fault exhibits a net slip of 0.7 mm/yr at depth which increases to 1.6 mm/yr where it is intersected by the Santa Monica fault in the near-surface. Model results suggest that nearly all faults in the region have an oblique component of slip at depth, so slip rate estimates of only dip or strike-slip may underestimate the total net slip rates and seismic hazards in the region.

This model provides state of the art simulations for land-sea thermally induced circulations. The model-predicted results agree favorably with available observed data. The effects of synoptic flow and sea breeze coupling on air pollution meteorological characteristics in this region, are demonstrated by a spatial and temporal presentation of various model predicted fields. A transport analysis based on predicted wind velocities indicated possible recirculation of pollutants back onto the Atlantic coast due to the sea breeze circulation.

    We surveyed four different river systems in the Greater Montreal region, upstream and downstream of entry points of contamination, from April 2007 to January 2009. The studied compounds belong to three different groups: PPCPs (caffeine, carbamazepine, naproxen, gemfibrozil, and trimethoprim), hormones (progesterone, estrone, and estradiol), and triazine herbicides and their metabolites (atrazine, deethylatrazine, deisopropylatrazine, simazine, and cyanazine). In the system A, B, and C having low flow rate and high TOC, we observed the highest detection frequencies and mass flows of PPCPs compared to the other compounds, reflecting discharge of urban contaminations through WWTPs and CSOs. However, in River D, having high flow rate and low TOC, comparable frequency of detection of triazine and their by-products and PPCPs, reflecting cumulative loads of these compounds from the Great Lakes as well as persistency against natural attenuation processes. Considering large differences in the removal efficiencies of caffeine and carbamazepine, a high ratio of caffeine/carbamazepine might be an indicative of a greater proportion of raw sewage versus treated wastewater in surface waters. In addition, caffeine appeared to be a promising indicator of recent urban fecal contaminations, as shown by the significant correlation with FC (R(2)=0.45), while carbamazepine is a good indicator of cumulative persistence compounds.

    This study investigates the mortality effect of primary and secondary PM2.5 related to ship exhaust in the Sydney greater metropolitan region of Australia. A detailed inventory of ship exhaust emissions was used to model a) the 2010/11 concentration of ship-related PM2.5 across the region, and b) the reduction in PM2.5 concentration that would occur if ships used distillate fuel with a 0.1% sulfur content at berth or within 300 km of Sydney. The annual loss of life attributable to 2010/11 levels of ship-related PM2.5 and the improvement in survival associated with use of low-sulfur fuel were estimated from the modelled concentrations. In 2010/11, approximately 1.9% of the region-wide annual average population weighted-mean concentration of all natural and human-made PM2.5 was attributable to ship exhaust, and up to 9.4% at suburbs close to ports. An estimated 220 years of life were lost by people who died in 2010/11 as a result of ship exhaust-related exposure (95% CIβ: 140-290, where CIβ is the uncertainty in the concentration-response coefficient only). Use of 0.1% sulfur fuel at berth would reduce the population weighted-mean concentration of PM2.5 related to ship exhaust by 25% and result in a gain of 390 life-years over a twenty year period (95% CIβ: 260-520). Use of 0.1% sulfur fuel within 300 km of Sydney would reduce the concentration by 56% and result in a gain of 920 life-years over twenty years (95% CIβ: 600-1200). Ship exhaust is an important source of human exposure to PM2.5 in the Sydney greater metropolitan region. This assessment supports intervention to reduce ship emissions in the GMR. Local strategies to limit the sulfur content of fuel would reduce exposure and will become increasingly beneficial as the shipping industry expands. A requirement for use of 0.1% sulfur fuel by ships within 300 km of Sydney would provide more than twice the mortality benefit of a requirement for ships to use 0.1% sulfur fuel at berth.

    Animals can require different habitat types throughout their annual cycles. When considering habitat prioritization, we need to explicitly consider habitat requirements throughout the annual cycle, particularly for species of conservation concern. Understanding annual habitat requirements begins with quantifying how far individuals move across landscapes between key life stages to access required habitats. We quantified individual interseasonal movements for greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) using radio-telemetry spanning the majority of the species distribution in Wyoming. Sage-grouse are currently a candidate for listing under the United States Endangered Species Act and Wyoming is predicted to remain a stronghold for the species. Sage-grouse use distinct seasonal habitats throughout their annual cycle for breeding, brood rearing, and wintering. Average movement distances in Wyoming from nest sites to summer-late brood-rearing locations were 8.1 km (SE = 0.3 km; n = 828 individuals) and the average subsequent distances moved from summer sites to winter locations were 17.3 km (SE = 0.5 km; n = 607 individuals). Average nest-to-winter movements were 14.4 km (SE = 0.6 km; n = 434 individuals). We documented remarkable variation in the extent of movement distances both within and among sites across Wyoming, with some individuals remaining year-round in the same vicinity and others moving over 50 km between life stages. Our results suggest defining any of our populations as migratory or non-migratory is innappropriate as individual strategies vary widely. We compared movement distances of birds marked using Global Positioning System (GPS) and very high frequency (VHF) radio marking techniques and found no evidence that the heavier GPS radios limited movement. Furthermore, we examined the capacity of the sage-grouse core regions concept to capture seasonal locations. As expected, we found the core regions approach, which was

    The current study researches the present-day stress state of the Earth's crust within the territory of Azerbaijan by using the database of the international research project "World Stress Map" (WSM). The present stress state was also assessed by exploring the effects of the contemporary topographic properties of Caucasus in three-dimensional frame. Aiming to explore the relative roles of regional tectonic conditions in the definition of stress state of Greater and Lesser Caucasus, stress distribution model was developed by the earthquake data (1998-2016) and by the standard techniques of stress field calculation. The results show that the stress orientations are influenced also by the combination of topography and crust thickness distribution even at very large depth. Stress data and earthquake focal mechanisms indicate that the stress state of the Earth's crust of the Greater and Lesser Caucasus is characterized by the compression predominantly oriented across the regional strike. The model results suggest that the Lesser Caucasus and Kur depression are rotating coherently, with little or no internal deformation in a counter-clockwise rotation located near the north-eastern corner of the Black Sea. Orientation of stress axes well consistent with earthquake focal mechanisms revealed that within Upper and Lower Crusts, earthquakes are predominantly thrust-faulting with a number of normal-faulting and some strike-slip faulting. The map of the focal mechanisms and stress distribution suggests that the research area is characterized by the thrust of horizontal compression trending north-north-east in the western part of the southern Caucasus. In the western part of Azerbaijan, the compression takes place between the Main Caucasus Fault and the Kur depression, which strikes south along the northern margin of the mountain range. In addition, a clear transition from the left-lateral strike slip to the predominantly right-lateral strike slip is observed in the southern of

    Evapotranspiration (ET) is a major component linking the water, energy, and carbon cycles. Understanding changes in ET and the relative contribution rates of human activity and of climate change at the basin scale is important for sound water resources management. In this study, changes in ET in the Heihe agricultural region in northwest China during 1984-2014 were examined using remotely-sensed ET data with the Soil and Water Assessment Tool (SWAT). Correlation analysis identified the dominant factors that influence change in ET per unit area and those that influence change in total ET. Factor analysis identified the relative contribution rates of the dominant factors in each case. The results show that human activity, which includes factors for agronomy and irrigation, and climate change, including factors for precipitation and relative humidity, both contribute to increases in ET per unit area at rates of 60.93% and 28.01%, respectively. Human activity, including the same factors, and climate change, including factors for relative humidity and wind speed, contribute to increases in total ET at rates of 53.86% and 35.68%, respectively. Overall, in the Heihe agricultural region, the contribution of human agricultural activities to increased ET was significantly greater than that of climate change.

    The most recent release of MODIS atmospheric product (Collection 6) is already used in studies concerning the greater Mediterranean region. However, an assessment of the differences and similarities of the last two MODIS collections (6 and 5.1) is missing. In this paper, a first comparison of the MODIS/Terra and Aqua Collection 6 and Collection 5.1 AOD at a wavelength of 550 nm (AOD550) data is presented with a focus on the Mediterranean region. It is shown that Collection 6 AODs are either higher or lower than Collection 5.1 AODs over different continental areas while, over ocean, Collection 6 AODs are higher almost everywhere (11% for MODIS/Terra and 8% for MODIS/Aqua). Generally, Collection 6 retrieves higher AODs than Collection 5.1, especially for MODIS/Terra. The evaluation of Collection 6 and 5.1 AOD550 data against sunphotometric observations from 23 AERONET stations in the area reveals that Collection 6 exhibits a better agreement with the ground-based data. The Collection 6 AOD550 data exhibit a statistically significant negative trend of the order of about -0.001/year (∼-0.5%/year) for MODIS/Terra and -0.002/year (∼-1.0%/year) for MODIS/Aqua. For the region studied, Collection 6 trends are largely reduced compared to Collection 5.1 trends by ∼0.003/year for MODIS/Terra data while for MODIS/Aqua data the trends have not changed significantly (only by ∼0.0003/year).

    As part of an European-South American study of deliberate violence cases of violence against women greater than or equal to 15 years of age and violence against and among children under the age of 15 years were registered at 3 Danish emergency wards and at the Institute of Forensic Medicine in Copenhagen. 352 cases of violence against women and 46 cases of violence against children were registered in the three emergency wards corresponding to rates of about 1.6/1000 per year for women, 0.6/1000 per year for boys and 0.7/1000 per year for girls in a provincial/rural district, the catchment region of Holbaek County Hospital, 3.4/1000 per year for women, 2.8/1000 per year for boys and 0.6/1000 per year for girls in a mainly middle income area of the metropolis Copenhagen, the catchment region of Frederiksberg Hospital, and 4.0/1000 per year for women, 4.0/1000 per year for boys and 0.9/1000 per year for girls in a mainly low income area of Copenhagen, the catchment region of the Rigshospital. Nineteen live adult female victims and 17 dead adult female victims of violence were registered in the Institute of Forensic Medicine in Copenhagen, where also one was registered as a victim of homicide. Nearly half of the adult live female victims of violence had been injured at home while this was the case for approximately three fourth of the dead victims. In 35% of the live cases the husband was the aggressor and in 12% a former cohabitant. In 71% of the homicide cases the husband was the aggressor. The live women appeared to have fewer but more serious lesions than men. The pattern of deliberate violence against women appears to be associated with socio-economic and cultural factors. In cases with a preceding quarrel there is statistically a link to alcohol intoxication. In half of the cases of violence against children the aggressor was known to the victim, in 15% the aggressor was one of the parents, while 42% of the cases were violence among children.

    The Endangered Species Act (ESA) continues to serve as one of the most powerful and contested federal legislative mandates for conservation. In the midst of heated debates, researchers, policy makers, and conservation practitioners champion the importance of cooperative conservation and social-ecological systems approaches, which forge partnerships at multiple levels and scales to address complex ecosystem challenges. However, few real-world examples exist to demonstrate how multifaceted collaborations among stakeholders who share a common goal of conserving at-risk species may be nested within a systems framework to achieve social and ecological goals. Here, we present a case study of Greater Sage-grouse (Centrocercus urophasianus) conservation efforts in the “Bi-State” region of California and Nevada, United States. Using key-informant interviews, we explored dimensions and drivers of this landscape-scale conservation effort. Three themes emerged from the interviews, including 1) ESA action was transformed into opportunity for system-wide conservation; 2) a diverse, locally based partnership anchored collaboration and engagement across multiple levels and scales; and 3) best-available science combined with local knowledge led to “certainty of effectiveness and implementation”—the criteria used by the US Fish and Wildlife Service to evaluate conservation efforts when making listing decisions. Ultimately, collaborative conservation through multistakeholder engagement at various levels and scales led to proactive planning and implementation of conservation measures and precluded the need for an ESA listing of the Bi-State population of Greater Sage-grouse. This article presents a potent example of how a systems approach integrating policy, management, and learning can be used to successfully overcome the conflict-laden and “wicked” challenges that surround at-risk species conservation.

    Measurements of SKS wave splitting beneath greater region of the central External Dinarides (Dalmatia, Croatia) were made in order to investigate seismic anisotropy in the upper mantle and the lithosphere. The area is located in the broad and complex Africa-Eurasia convergent plate boundary zone, where Adriatic microplate interacts with the External Dinarides. We used broadband recordings (more than 3500 analyzed seismograms) from 10 permanent stations situated along the Croatian coastal region. The splitting parameters - fast axis and delay time - were measured using the Silver and Chan method. Seismic anisotropy was observed on all stations. Fast axis directions are fairly uniformly oriented approximately in the NE-SW to NNE-SSW direction, thus perpendicularly to the strike of the Dinarides. Average delay times range between 0.7 and 1.0 seconds. Slight counter-clockwise rotation in average fast axis directions was observed for the stations in the northern part of the studied area, as well as a small increase in average delay times, with respect to the stations in the southern part. We also observed differences in splitting parameters for back-azimuths sampling different tectonic units (Euroasian plate and Adria), however, due to poor back-azimuthal coverage and limited dataset, more measurements have to be made to enable reliable validation of this observation. Fast axis directions coincide with the direction of the maximum tectonic pressure in the crust and with observed fast directions of P-waves in the crust, which might imply a significant crustal component of measured anisotropy, alongside the component resulting from the upper mantle structures.

    The Greater Cape Floristic Region (GCFR) in South Africa has been extensively investigated for its phenomenal angiosperm diversity. A key emergent pattern is the occurrence of older plant lineages in the southern Fynbos biome and younger lineages in the northern Succulent Karoo biome. We know practically nothing, however, about the evolutionary history of the animals that pollinate this often highly-specialized flora. In this study, we explore the evolutionary history of an important GCFR fly pollinator, Megapalpus capensis, and ask whether it exhibits broadly congruent genetic structuring and timing of diversification to flowering plants within these biomes. We find that the oldest M. capensis lineages originated in Fynbos during the Miocene, while younger Succulent Karoo lineages diverged in the Pliocene and correspond to the proposed age of this recent biome. A strong signature of population expansion is also recovered for flies in this arid biome, consistent with recent colonization. Our first investigation into the evolutionary history of GCFR pollinators thus supports a recent origin of the SK biome, as inferred from angiosperm phylogenies, and suggests that plants and pollinators may have co-diverged within this remarkable area.

    Safe drinking water is critical to human health and development. In rural sub-Saharan Africa, most improved water sources are boreholes with handpumps; studies suggest that up to one third of these handpumps are nonfunctional at any given time. This work presents findings from a secondary analysis of cross-sectional data from 1509 water sources in 570 communities in the rural Greater Afram Plains (GAP) region of Ghana; one of the largest studies of its kind. 79.4% of enumerated water sources were functional when visited; in multivariable regressions, functionality depended on source age, management, tariff collection, the number of other sources in the community, and the district. A Bayesian network (BN) model developed using the same data set found strong dependencies of functionality on implementer, pump type, management, and the availability of tools, with synergistic effects from management determinants on functionality, increasing the likelihood of a source being functional from a baseline of 72% to more than 97% with optimal management and available tools. We suggest that functionality may be a dynamic equilibrium between regular breakdowns and repairs, with management a key determinant of repair rate. Management variables may interact synergistically in ways better captured by BN analysis than by logistic regressions. These qualitative findings may prove generalizable beyond the study area, and may offer new approaches to understanding and increasing handpump functionality and safe water access.

    Characterizing the precipitation variability at a range of spatial and temporal scales is of critical importance for many applications in hydrometeorology. Among a variety of spatiotemporal scales, the variability at the scale of sub-daily and ˜10 km has attracted more interests due to its critical role in understanding the physical processes of precipitation formation. Using the hourly precipitation observations from 118 gauge stations and a weather radar in the Greater Beijing Region (GBR) during 2008-2012, we investigate the small scale spatiotemporal characteristics of precipitation and discuss the appropriate observational approach for capturing variability of precipitation over this region. In general, the south central and northeastern GBR receives more intense precipitation than other parts. The diurnal cycle of precipitation amount (PA) peaks in the evening and decreases till noon, whereas precipitation intensity (PI) and precipitation frequency (PF) both have two peaks. The stronger peaks of PI and PF occur in the evening whereas the weaker ones appear in the early nighttime and in the afternoon. Remarkable spatial heterogeneity also exists in the diurnal patterns of PA, PI and PF over the GBR. Rainstorms extracted from radar data feature in short duration (11.4 h in average) and highly localized patterns (4.31-20.58/1.85-9.10 km in major/minor radius direction). The estimated diurnal cycles of PA, PI and PF are found to depend on the gauge density in a sensitivity analysis, where a gauge density ratio of 0.6 (corresponding to 30 gauges in total with a representative area of 239.5 km2 per gauge) is identified as adequate to capture the temporal characteristics of precipitation in the plain area of GBR. However, such a gauge density ratio (i.e. 0.6) is incapable for resolving the spatial characteristics of precipitation in GBR. As such, different instruments (e.g. gauge network, weather radar, etc.) and multiple data sources are suggested to be jointly

    Rice is the most important cereal crop in Kenya coming third after maize and wheat. It forms a very important diet for a majority of families in Kenya. The demand for rice in Kenya has seen a dramatic increase over the last few years while production has remained low. This is because rice production has been faced by serious constraints notably plant diseases of which the most devastating is rice blast. Rice blast is known to cause approximately 60% -100% yield losses. It is caused by an Ascomycete fungus called Magnaporthe Oryzae. The aim of this study was to investigate the impact of rice blast disease on the livelihood of the local farmers in Greater Mwea region and develop a rice blast disease distribution map using GIS approach. The study methodology employed a questionnaire survey which were subjected to sample population of households in the 7 sections with 70 blocks within Mwea region. The collected data was analysed using SAS Version 9.1. Descriptive statistics were used to summarize the household characteristics, the farm characteristics and the farmers' perceptions of rice blast disease. In the questionnaire, farmers' response on whether they had been affected by rice blast disease and the total production per acreage was used to develop an attribute table with GPS points. The GPS points were interpolated to create a geographical distribution map of rice blast disease. From the research findings almost all the farmers' had awareness and knowledge of rice blast disease, 98% of the farmers interviewed were aware of rice blast disease. Out of the 98% with knowledge and awareness 76% have been affected by the disease, while 24% have never been affected. Farmers attributed rice blast disease to a range of different causes, including excessive use of nitrogen fertilizer, water shortage, lack of proper drainage canal and due to climate change. Majority of the farmers interviewed (72%) did not engage themselves in any other socio-economic activity even after

    Using velocity profiles from sites in Japan, California, Turkey, and Europe, we find that the time-averaged shear-wave velocity to 30 m (V S30), used as a proxy for site amplification in recent ground-motion prediction equations (GMPEs) and building codes, is strongly correlated with average velocities to depths less than 30 m (V Sz, with z being the averaging depth). The correlations for sites in Japan (corresponding to the KiK-net network) show that V S30 is systematically larger for a given V Sz than for profiles from the other regions. The difference largely results from the placement of the KiK-net station locations on rock and rocklike sites, whereas stations in the other regions are generally placed in urban areas underlain by sediments. Using the KiK-net velocity profiles, we provide equations relating V S30 to V Sz for z ranging from 5 to 29 m in 1-m increments. These equations (and those for California velocity profiles given in Boore, 2004b) can be used to estimate V S30 from V Sz for sites in which velocity profiles do not extend to 30 m. The scatter of the residuals decreases with depth, but, even for an averaging depth of 5 m, a variation in log V S30 of 1 standard deviation maps into less than a 20% uncertainty in ground motions given by recent GMPEs at short periods. The sensitivity of the ground motions to V S30 uncertainty is considerably larger at long periods (but is less than a factor of 1.2 for averaging depths greater than about 20 m). We also find that V S30 is correlated with V Sz for z as great as 400 m for sites of the KiK-net network, providing some justification for using V S30 as a site-response variable for predicting ground motions at periods for which the wavelengths far exceed 30 m.

    Objectives To explore the “how” and “why” of care decision making by frontline providers of maternal and newborn services in the Greater Accra region of Ghana and determine appropriate interventions needed to support its quality and related maternal and neonatal outcomes. Methods A cross sectional and descriptive mixed method study involving a desk review of maternal and newborn care protocols and guidelines availability, focus group discussions and administration of a structured questionnaire and observational checklist to frontline providers of maternal and newborn care. Results Tacit knowledge or ‘mind lines’ was an important primary approach to care decision making. When available, protocols and guidelines were used as decision making aids, especially when they were simple handy tools and in situations where providers were not sure what their next step in management had to be. Expert opinion and peer consultation were also used through face to face discussions, phone calls, text messages, and occasional emails depending on the urgency and communication medium access. Health system constraints such as availability of staff, essential medicines, supplies and equipment; management issues (including leadership and interpersonal relations among staff), and barriers to referral were important influences in decision making. Frontline health providers welcomed the idea of interventions to support clinical decision making and made several proposals towards the development of such an intervention. They felt such an intervention ought to be multi-faceted to impact the multiple influences simultaneously. Effective interventions would also need to address immediate challenges as well as more long-term challenges influencing decision-making. Conclusion Supporting frontline worker clinical decision making for maternal and newborn services is an important but neglected aspect of improved quality of care towards attainment of MDG 4 & 5.

    The Greater Horn of Africa (GHA) has distinct climate characteristics compared to the rest of the continent. The GHA is replete with complex terrain comprising of some of the known tropical glacier covered high mountains of Kilimanjaro, Kenya and Rwenzori as well as the Great Rift Valley System (GRVS). The region also has several freshwater lakes that include Lake Victoria (second largest freshwater lake), and Lake Tanganyika (the second largest deepest freshwater lake). As a whole the complex GHA terrain presents an enabling environment where local and large scale climate systems frequently interact to create highly variable climate in both space and time. At the same time, inter-annual variability of the GHA climate is linked to perturbations in the global SSTs, especially over the equatorial Pacific and Indian Ocean basins, and to some extent, the Atlantic Ocean. These three global oceans, all at the same time or each at different times, intriguingly influence the interannual variability of the GHA climate. Interactions and feedbacks among these multiple climate drivers over the region present challenges in quantitative understanding of regional climate variability and changes based on typical empirical techniques. Therefore, there is need to also employ physically-based, regional climate models (RCMs) that can offer scope and capability to unveil cause-effect relationships between regional climate variability and individual or combination of processes. However, representation of the multiple sources of forcing to the GHA climate also poses a great challenge to RCMs as well. This presentation will give an overview of the AFRMIP project, whose primary objective is to undertake a systematic and comprehensive audit of the deficiencies and uncertainties in regional model simulations of the GHA climate. The project specifically seeks to build a coalition of a regional climate modeling community to address the following issues; (i) representation of the GHA

    Background: Operative management of pediatric fractures is an expected competency in the specialty of Orthopedic Surgery. However, specialized pediatric centres may be providing care for increasing numbers of patients with fractures previously treated at community hospitals. The primary objective of this study was to examine trends in presentation of children with fractures to a specialized pediatric centre. Methods: We performed a detailed chart review to examine trends in presentation of children aged 14 years or less with supracondylar humerus or femur fractures to a specialized pediatric centre (Hospital for Sick Children, Toronto) from anywhere in the Greater Toronto Area between Apr. 1, 2008, and Mar. 31, 2015. Consecutive patients admitted to hospital and requiring operative intervention for a supracondylar humerus or femur fracture were considered. We calculated changes in operation incidence rates per year using multivariable negative binomial regression models. Results: A total of 945 children with supracondylar humerus fractures and 421 with femur fractures underwent operative intervention during the study period. The baseline characteristics of the 2 groups were similar irrespective of which year fixation occurred. The annual incidence rate of supracondylar humerus fractures increased from 108 to 169 (56.5%) over the study period, at an adjusted rate of 7.5% per year (adjusted incidence rate ratio [IRR] 1.075, 95% confidence interval [CI] 1.072-1.079, p < 0.001). The annual incidence rate of femur fractures increased from 49 to 69 (40.8%), at an adjusted rate of 5.3% per year (adjusted IRR 1.053, 95% CI 1.044-1.062, p < 0.001). Significant increases were observed independent of fracture classification, stabilization method, whether patients were transferred from an outside hospital or presented directly, patient geographic location or the season in which the fracture occurred. Interpretation: Adjusted annual incidence rates of supracondylar humerus and

  2. The impact of heat on mortality and morbidity in the Greater Metropolitan Sydney Region: a case crossover analysis

    2013-01-01

    Background This study examined the association between unusually high temperature and daily mortality (1997–2007) and hospital admissions (1997–2010) in the Sydney Greater Metropolitan Region (GMR) to assist in the development of targeted health programs designed to minimise the public health impact of extreme heat. Methods Sydney GMR was categorized into five climate zones. Heat-events were defined as severe or extreme. Using a time-stratified case-crossover design with a conditional logistic regression model we adjusted for influenza epidemics, public holidays, and climate zone. Odds ratios (OR) and 95% confidence intervals were estimated for associations between daily mortality and hospital admissions with heat-event days compared to non-heat event days for single and three day heat-events. Results All-cause mortality overall had similar magnitude associations with single day and three day extreme and severe events as did all cardiovascular mortality. Respiratory mortality was associated with single day and three day severe events (95thpercentile, lag0: OR = 1.14; 95%CI: 1.04 to 1.24). Diabetes mortality had similar magnitude associations with single day and three day severe events (95thpercentile, lag0: OR = 1.22; 95%CI: 1.03 to 1.46) but was not associated with extreme events. Hospital admissions for heat related injuries, dehydration, and other fluid disorders were associated with single day and three day extreme and severe events. Contrary to our findings for mortality, we found inconsistent and sometimes inverse associations for extreme and severe events with cardiovascular disease and respiratory disease hospital admissions. Controlling for air pollutants did not influence the mortality associations but reduced the magnitude of the associations with hospital admissions particularly for ozone and respiratory disease. Conclusions Single and three day events of unusually high temperatures in Sydney are associated with similar magnitude increases

    Stahr, Donald William, III

    The Himalayan orogen provides a natural laboratory to test models of orogenic development due to large-scale continental collision. The Greater Himalayan Series (GHS), a lithotectonic unit continuous along the entire length of the belt, comprises the metamorphic core of the Himalayan orogen and underlies the highest topography. GHS rocks are exposed as a moderately northdipping slab bounded below by the Main Central Thrust (MCT) and above by the South Tibetan Detachment System (STDS) of normal faults. Coeval reverse- and normal-sense motion on the crustal-scale MCT and STDS ductile shear zones allows the GHS to be modeled as an extruded wedge or channel of mid-crustal material. Due to this unique tectonic setting, the deformation path of rocks within the bounding shear zones and throughout the core of the GHS profoundly influences the efficiency of extrusion and exhumation processes. Attempts to quantify GHS deformation and metamorphic evolution have provided significant insight into Himalayan orogenic development, but these structural and petrologic studies are often conducted in isolation. Penetrative deformation fabrics developed under mid-upper amphibolite facies conditions within the GHS argue that deformation and metamorphism were coupled, and this should be considered in studies aimed at quantifying GHS teconometamorphic evolution. This work focuses on two projects related to the coupled deformation, thermal and metamorphic evolution during extrusion and exhumation of the GHS, focused on the lower and upper margins of the slab. A detailed examination of the P--T history of a schist collected from within the MCT zone of the Sutlej River, NW India, provides insight into the path experienced by these rocks as they traveled through the crust in response to the extreme shortening related to India-Asia collision. Combined forward thermodynamic and diffusion modeling indicates compositional zoning preserved in garnet has remained unmodified since growth and can be

    The Copenhagen City Heart Study, also known as “Østerbroundersøgelsen”, is a large prospective cardio-vascular population study of 20,000 women and men that was launched in 1975 by Dr Peter Schnohr and Dr Gorm Jensen together with statistician Jørgen Nyboe and Prof. A. Tybjærg Hansen. The original purpose of the study was to focus on prevention of coronary heart disease and stroke. During the years many other aspects have been added to the study: pulmonary diseases, heart failure, arrhythmia, alcohol, arthrosis, eye diseases, allergy, epilepsia, dementia, stress, vital exhaustion, social network, sleep-apnoe, ageing and genetics. In this review we highlight unique aspects of the Copenhagen City Heat Study (CCHS) and its outcome in investigations of clinical and molecular aspects of health and disease in the regional and global population. To increase the impact of population studies with a focus on risk and prevention of cardiovascular and related diseases and to maximize the likelihood of identifying disease causes and effective therapeutics, lessons learned from past research should be applied to the design, implementation and interpretation of future studies.

    In this paper the city of Copenhagen is used as a starting point to highlight some critical historical events, both concerning the exchange of ideas between the physicist Wolfgang Pauli and C.G. Jung and the history of psychotherapy in Scandinavia. Pauli's years in Copenhagen under the influence of Niels Bohr and his philosophy prepared him mentally to receiveC.G. Jung's ideas. The paper also recounts the one occasion that Jung was in Scandinavia, attending the 9th conference of the General Medical Society for Psychotherapy in Copenhagen, just before going to New York in 1937 to give his final seminars on Pauli's dreams. The reason for focusing on these particular events is that they also constitute part of the history of the reception of psychodynamic psychology in Sweden and Scandinavia. © 2014, The Society of Analytical Psychology.

    Understanding the geographic, temporal, and environmental contexts of human evolution requires the ability to compare wide-ranging datasets collected from multiple research disciplines. Paleoanthropological field- research projects are notoriously independent administratively even in regions of high transdisciplinary importance. As a result, valuable opportunities for the integration of new and archival datasets spanning diverse archaeological assemblages, paleontological localities, and stratigraphic sequences are often neglected, which limits the range of research questions that can be addressed. Using geoinformatic tools we integrate spatial, temporal, and semantically disparate paleoanthropological and geological datasets from the Hadar sedimentary basin of the Afar Rift, Ethiopia. Applying newly integrated data to investigations of fossil- rich sediments will provide the geospatial framework critical for addressing fundamental questions concerning hominins and their paleoenvironmental context. We present a preliminary cyberinfrastructure for data management that will allow scientists, students, and interested citizens to interact with, integrate, and visualize data from the Afar region. Examples of our initial integration efforts include generating a regional high-resolution satellite imagery base layer for georeferencing, standardizing and compiling multiple project datasets and digitizing paper maps. We also demonstrate how the robust datasets generated from our work are being incorporated into a new, digital module for Arizona State University's Hadar Paleoanthropology Field School - modernizing field data collection methods, on-the-fly data visualization and query, and subsequent analysis and interpretation. Armed with a fully fused database tethered to high-resolution satellite imagery, we can more accurately reconstruct spatial and temporal paleoenvironmental conditions and efficiently address key scientific questions, such as those regarding the

    2017-05-01

    The Copenhagen problem is a well-known case of the famous restricted three-body problem. In this work instead of considering Newtonian potentials and forces we assume that the two primaries create a quasi-homogeneous potential, which means that we insert to the inverse square law of gravitation an inverse cube corrective term in order to approximate various phenomena as the radiation pressure of the primaries or the non-sphericity of them. Based on this new consideration we investigate the equilibrium locations of the small body and their parametric dependence, as well as the zero-velocity curves and surfaces for the planar motion, and the evolution of the regions where this motion is permitted when the Jacobian constant varies.

    2016-05-01

    The long-standing conceptual controversies concerning the interpretation of nonrelativistic quantum mechanics are argued, on one hand, to be due to its incompleteness, as affirmed by Einstein. But on the other hand, it appears to be possible to complete it at least partially, as Bohr might have appreciated it, in the framework of its standard mathematical formalism with observables as appropriately defined self-adjoint operators. This completion of quantum mechanics is based on the requirement on laboratory physics to be effectively confined to a bounded space region and on the application of the von Neumann deficiency theorem to properly define a set of self-adjoint extensions of standard observables, e.g. the momenta and the Hamiltonian, in terms of certain isometries on the region boundary. This is formalized mathematically in the setting of a boundary ontology for the so-called Qbox in which the wave function acquires a supplementary dependence on a set of Additional Boundary Variables (ABV). It is argued that a certain geometric subset of the ABV parametrizing Quasi-Periodic Translational Isometries (QPTI) has a particular physical importance by allowing for the definition of an ontic wave function, which has the property of epitomizing the spatial wave function “collapse.” Concomitantly the standard wave function in an unbounded geometry is interpreted as an epistemic wave function, which together with the ontic QPTI wave function gives rise to the notion of two-wave duality, replacing the standard concept of wave-particle duality. More generally, this approach to quantum physics in a bounded geometry provides a novel analytical basis for a better understanding of several conceptual notions of quantum mechanics, including reality, nonlocality, entanglement and Heisenberg’s uncertainty relation. The scope of this analysis may be seen as a foundational update of the multiple versions 1.x of the Copenhagen interpretation of quantum mechanics, which is

    Urban water planning, development, and management are many sectored, costly efforts, subject to a multitude of controls and demands including those imposed by nature. One primary concern in development is for providing a dependable and safe water supply. In spite of a bountiful natural availability, the process of satisfying consumer needs involves the resolution of a variety of problems, not the least of which are cooperation and coordination among suppliers. One of the fundamental requisites in seeking sound solutions to developmental and environmental problems is inventory documentation. This map is one facet of documentation; the data listing, given on sheet 2, is the companion inventory. These supplement State, regional, and local efforts directed toward both long-range planning and current evaluation programs. Such documentation also assists the assessment of the effect of one water-management subsystem on hydrologic characteristics.

    An intensive hydrogeologic investigation, mandated by U.S. Congress and centered on the Norris-Mammoth corridor was conducted by USGS and other scientists during 1988-90 to determine the effects of using thermal water from a private well located in the Corwin Springs Known Geothermal Resources Area, Montana, on the thermal springs of Yellowstone National Park (YNP), especially Mammoth Hot Springs. As part of this investigation, we carried out a detailed study of the isotopic and chemical compositions of meteoric water from cold springs and wells, of thermal water, especially from the Norris-Mammoth corridor and of snow. Additional sampling of meteoric and thermal waters from YNP and surrounding region in northwest Wyoming, southwest Montana and southeast Idaho was carried out in 1991-92 to characterize the distribution of water isotopes in this mountainous region and to determine the origin and possible recharge locations of thermal waters in and adjacent to the Park. The D and 18O values for 40 snow samples range from ?88 to ?178? and ?12.5 to ?23.9?, respectively, and define a well constrained line given by D = 8.2 18O + 14.7 (r2 = 0.99) that is nearly identical to the Global Meteoric Water Line. The D and 18O values of 173 cold water samples range from ?115 to ?153? and ?15.2 to ?20.2?, respectively, and exhibit a similar relationship although with more scatter and with some shift to heavier isotopes, most likely due to evaporation effects. The spatial distribution of cold-water isotopes shows a roughly circular pattern with isotopically lightest waters centered on the mountains and high plateau in the northwest corner of Yellowstone National Park and becoming heavier in all directions. The temperature effect due to altitude is the dominant control on stable water isotopes throughout the region; however, this effect is obscured in narrow 'canyons' and areas of high topographic relief.

  17. The emergent Copenhagen interpretation of quantum mechanics

    2014-05-01

    We introduce a new and conceptually simple interpretation of quantum mechanics based on reduced density matrices of sub-systems from which the standard Copenhagen interpretation emerges as an effective description of macroscopically large systems. This interpretation describes a world in which definite measurement results are obtained with probabilities that reproduce the Born rule. Wave function collapse is seen to be a useful but fundamentally unnecessary piece of prudent book keeping which is only valid for macro-systems. The new interpretation lies in a class of modal interpretations in that it applies to quantum systems that interact with a much larger environment. However, we show that it does not suffer from the problems that have plagued similar modal interpretations like macroscopic superpositions and rapid flipping between macroscopically distinct states. We describe how the interpretation fits neatly together with fully quantum formulations of statistical mechanics and that a measurement process can be viewed as a process of ergodicity breaking analogous to a phase transition. The key feature of the new interpretation is that joint probabilities for the ergodic subsets of states of disjoint macro-systems only arise as emergent quantities. Finally we give an account of the EPR-Bohm thought experiment and show that the interpretation implies the violation of the Bell inequality characteristic of quantum mechanics but in a way that is rather novel. The final conclusion is that the Copenhagen interpretation gives a completely satisfactory phenomenology of macro-systems interacting with micro-systems.

    The development of the pharmacy in the 19th and 20th centuries is illustrated by education and activity in the Dolphin Pharmacy in Copenhagen. The career within chemistry and pharmacy started with an apprenticeship of 4 year in the pharmacies. The Dolphin Pharmacy was responsible for part of the examination, i.e. the examination of the preparation of medicine. Passing the examination the chemist's assistant was free to prepare and to dispense medicine. Graduation as a pharmaceutical candidate was necessary to obtain license. Lectures in chemistry, physics, pharmacy, botany and pharmacognosy were obtained at the University of Copenhagen and the Polytechnic, but no curriculum was available. A rational education was obtained later on by the establishment of the School of Pharmacy in 1892. The proprietor pharmacists of the Dolphin Pharmacy were excellent scientists who contributed to the development of pharmacy. Pictures of the pharmacy from about the 1930s show the manufacture of medicines on the basis of a prescription and a pharmacopoeia. Ointments containing zinc white, sulphur and tar were used for various skin diseases and for the tiresome cough; cough mixtures containing codeine or extract of ipecacuanha root were used. In the 1930s the medicine for injection was sterilized and the tablet machine was the breakthrough for a rational production in the pharmacy. However, at the end of the 1900s it was no more possible to compete with the pharmaceutical industry and all the production of medicine was taken over by the industry.

    The North Sea is one of the areas with the highest ship traffic densities worldwide. At any time, about 3000 ships are sailing its waterways. Previous scientific publications have shown that ships contribute significantly to atmospheric concentrations of NOx, particulate matter and ozone. Especially in the case of particulate matter and ozone, this influence can even be seen in regions far away from the main shipping routes. In order to quantify the effects of North Sea shipping on air quality in its bordering states, it is essential to determine the emissions from shipping as accurately as possible. Within Interreg IVb project Clean North Sea Shipping (CNSS), a bottom-up approach was developed and used to thoroughly compile such an emission inventory for 2011 that served as the base year for the current emission situation. The innovative aspect of this approach was to use load-dependent functions to calculate emissions from the ships' current activities instead of averaged emission factors for the entire range of the engine loads. These functions were applied to ship activities that were derived from hourly records of Automatic Identification System signals together with a database containing the engine characteristics of the vessels that traveled the North Sea in 2011. The emission model yielded ship emissions among others of NOx and SO2 at high temporal and spatial resolution that were subsequently used in a chemistry transport model in order to simulate the impact of the emissions on pollutant concentration levels. The total emissions of nitrogen reached 540 Gg and those of sulfur oxides 123 Gg within the North Sea - including the adjacent western part of the Baltic Sea until 5° W. This was about twice as much of those of a medium-sized industrialized European state like the Netherlands. The relative contribution of ships to, for example, NO2 concentration levels ashore close to the sea can reach up to 25 % in summer and 15 % in winter. Some hundred kilometers

    With more than a quarter of its population born overseas, Melbourne, Australia, is rapidly changing from an all-white British outpost to a multicultural, multilingual community. Since the "white" Australian policy was abandoned after World War II, 3 million immigrants from 100 different countries have moved to Australia. Most of the immigrants come from New Zealand, Rhodesia, South Africa, Britain, Ireland, Greece, Turkey, Yugoslavia, Poland, and Indochina. Melbourne is Australia's 2nd largest city and houses 1 out of 5 Australians. Its 1984 population was 2,888,400. Melbourne's housing pattern consists of subdivisions; 75% of the population live in detached houses. Between 1954 and 1961 Melbourne grew at an annual rate of 3.5%; its growth rate between 1961 and 1971 still averaged 2.5%. In the 1970s the growth rate slowed to 1.4%. Metropolitan Melbourne has no central government but is divided into 56 councils and 8 regions. Both Australia's and Melbourne's fertility rates are high compared to the rest of the developed world, partly because of their younger age structure. 41% of Melbourne's population was under age 24 in 1981. Single-person households are growing faster than any other type. 71% of the housing is owner-occupied; in 1981 the median sized dwelling had 5.2 rooms. Public housing only accounts for 2.6% of all dwellings. Fewer students graduate from high school in Australia than in other developed countries, and fewer graduates pursue higher education. Melbourne's suburban sprawl promotes private car travel. In 1980 Melbourne contained more than 28,000 retail establishments and 4200 restaurants and hotels. Industry accounts for 30% of employment, and services account for another 30%. Its largest industries are motor vehicles, clothing, and footware. Although unemployment reached 10% after the 1973 energy crisis, by 1985 it was down to 6%.

    As expected, delegates at the United Nations Ozone Layer Conference in Copenhagen sped up ozone depleter phaseouts from the 1987 Montreal Protocol and the 1990 London amendments. The changes bring the worldwide production phaseout of chlorofluorocarbons (CFCs) and other ozone depleters in developed countries in line with U.S. and European plans announced earlier this year. Adjustments to the protocol, which are binding on the signatories, change the phaseout for CFC, carbon tetrachloride, and methyl chloroform production and consumption to January 1, 1996 from 2000. The 75% reduction of 1986 levels from CFCs by January 1, 1994 is a compromise between European pressure for an 85% cut and the US goal of 70%. Halon production is to end January 1, 1994, as anticipated. Developing countries continue to have a 10-year grace period. Friends of the Earth ozone campaign director Liz Cook counters that the phaseout dates were scheduled with concern for the chemical industry, not for the ozone layer.

    The Copenhagen problem is a simple model in celestial mechanics. It serves to investigate the behavior of a small body under the gravitational influence of two equally heavy primary bodies. We present a partition of orbits into classes of various kinds of regular motion, chaotic motion, escape and crash. Collisions of the small body onto one of the primaries turn out to be unexpectedly frequent, and their probability displays a scale-free dependence on the size of the primaries. The analysis reveals a high degree of complexity so that long term prediction may become a formidable task. Moreover, we link the results to chaotic scattering theory and the theory of leaking Hamiltonian systems.

    Background and Aims Genome duplication is widely acknowledged as a major force in the evolution of angiosperms, although the incidence of polyploidy in different floras may differ dramatically. The Greater Cape Floristic Region of southern Africa is one of the world's biodiversity hotspots and is considered depauperate in polyploids. To test this assumption, ploidy variation was assessed in a widespread member of the largest geophytic genus in the Cape flora: Oxalis obtusa. Methods DNA flow cytometry complemented by confirmatory chromosome counts was used to determine ploidy levels in 355 populations of O. obtusa (1014 individuals) across its entire distribution range. Ecological differentiation among cytotypes was tested by comparing sets of vegetation and climatic variables extracted for each locality. Key Results Three majority (2x, 4x, 6x) and three minority (3x, 5x, 8x) cytotypes were detected in situ, in addition to a heptaploid individual originating from a botanical garden. While single-cytotype populations predominate, 12 mixed-ploidy populations were also found. The overall pattern of ploidy level distribution is quite complex, but some ecological segregation was observed. Hexaploids are the most common cytotype and prevail in the Fynbos biome. In contrast, tetraploids dominate in the Succulent Karoo biome. Precipitation parameters were identified as the most important climatic variables associated with cytotype distribution. Conclusions Although it would be premature to make generalizations regarding the role of genome duplication in the genesis of hyperdiversity of the Cape flora, the substantial and unexpected ploidy diversity in Oxalis obtusa is unparalleled in comparison with any other cytologically known native Cape plant species. The results suggest that ploidy variation in the Greater Cape Floristic Region may be much greater than currently assumed, which, given the documented role of polyploidy in speciation, has direct implications for radiation

    The science of global warming has reached a consensus on the high likelihood of substantial warming over the coming century. Nations have taken only limited steps to reduce greenhouse gas emissions since the first agreement in Kyoto in 1997, and little progress was made at the Copenhagen meeting in December 2009. The present study examines alternative outcomes for emissions, climate change, and damages under different policy scenarios. It uses an updated version of the regional integrated model of climate and the economy (RICE model). Recent projections suggest that substantial future warming will occur if no abatement policies are implemented. The model also calculates the path of carbon prices necessary to keep the increase in global mean temperature to 2 °C or less in an efficient manner. The carbon price for 2010 associated with that goal is estimated to be $59 per ton (at 2005 prices), compared with an effective global average price today of around $5 per ton. However, it is unlikely that the Copenhagen temperature goal will be attained even if countries meet their ambitious stated objectives under the Copenhagen Accord. PMID:20547856

The model also calculates the path of carbon prices necessary to keep the increase in global mean temperature to 2 degrees C or less in an efficient manner. The carbon price for 2010 associated with that goal is estimated to be $59 per ton (at 2005 prices), compared with an effective global average price today of around $5 per ton. However, it is unlikely that the Copenhagen temperature goal will be attained even if countries meet their ambitious stated objectives under the Copenhagen Accord.

    The primary goal of managing MSW incineration residues is to avoid any impact on human health or the environment. Incineration residues consist of bottom ash, which is generally considered as rather harmless and fly ash which usually contains compounds which are potentially harmful for public health. Small quantities of ash (both bottom and fly) are produced currently in Greece, mainly from the healthcare waste incineration facility in Attica region. Once incineration plants for MSW (currently under planning) are constructed in Greece, the produced ash quantities will increase highly. Thus, it is necessary to organize, already at this stage, a roadmap towards disposal/recovery methods of these ash quantities expected. Certain methods, related to the treatment of the future generated ash which are more appropriate to be implemented in Greece are highlighted in the present paper. The performed analysis offers a waste management approach, having 2016 as a reference year for two different incineration rates; 30% and 100% of the remaining MSW after recycling process. The results focus on the two greater regions of Greece: Attica and Central Macedonia. The quantity of potential future ash generation ranges from 137 to 459 kt for Attica region and from 62 to 207 kt for central Macedonia region depending on the incineration rate applied. Three alternative scenarios for the treatment of each kind of ash are compiled and analysed. Metal recovery and reuse as an aggregate in concrete construction proved to be the most advantageous -in terms of economy-bottom ash management scenario. Concerning management of the fly ash, chemical treatment with phosphoric solution addition results to be the lowest total treatment cost and is considered as the most profitable solution. The proposed methodology constitutes a safe calculation model for operators of MSW incineration plants regardless of the region or country they are located in.

  9. A numerical model simulation of the regional air pollution meteorology of the greater Chesapeake Bay area—summer day case study

    The mesoscale numerical model of the University of Virginia (UVMM), has been applied to the greater Chesapeake Bay area in order to provide a detailed description of the air pollution meteorology during a typical summer day. This model provides state of the art simulations for land-sea thermally induced circulations. The model-predicted results agree favorably with available observed data. The effects of synoptic flow and sea breeze coupling on air pollution meteorological characteristics in this region, are demonstrated by a spatial and temporal presentation of various model predicted fields. A transport analysis based on predicted wind velocities indicated possible recirculation of pollutants back onto the Atlantic coast due to the sea breeze circulation.

    A global HIV-1 vaccine will likely need to induce immune responses against conserved HIV-1 regions to contend with the profound genetic diversity of HIV-1. Here we evaluated the capacity of immunogens consisting of only highly conserved HIV-1 sequences that are aimed at focusing cellular immune responses on these potentially critical regions. We assessed in rhesus monkeys the breadth and magnitude of T lymphocyte responses elicited by adenovirus vectors expressing either full-length HIV-1 Gag/Pol/Env immunogens or concatenated immunogens consisting of only highly conserved HIV-1 sequences. Surprisingly, we found that the full-length immunogens induced comparable breadth (P = 1.0) and greater magnitude (P = 0.01) of CD8+ T lymphocyte responses against conserved HIV-1 regions compared with the conserved-region-only immunogens. Moreover, the full-length immunogens induced a 5-fold increased total breadth of HIV-1-specific T lymphocyte responses compared with the conserved-region-only immunogens (P = 0.007). These results suggest that full-length HIV-1 immunogens elicit a substantially increased magnitude and breadth of cellular immune responses compared with conserved-region-only HIV-1 immunogens, including greater magnitude and comparable breadth of responses against conserved sequences.

    The enhancement of warming rates with elevation, the so-called elevation-dependent warming (EDW), is one of the clearest regional expressions of global warming. Real sentinels of climate and environmental changes, mountains have experienced more rapid and intense warming rates in the recent decades, leading to serious impacts on mountain ecosystems and downstream societies, some of which are already occurring. In this study we use the historical and scenario simulations of one state-of-the-art global climate model, the EC-Earth GCM, run at five different spatial resolutions, from ˜125 km to ˜16 km, to explore the existence, characteristics and driving mechanisms of EDW in three different mountain regions of the world - the Colorado Rocky Mountains, the Greater Alpine Region and the Tibetan Plateau-Himalayas. The aim of this study is twofold: to investigate the impact (if any) of increasing model resolution on the representation of EDW and to highlight possible differences in this phenomenon and its driving mechanisms in different mountain regions of the northern hemisphere. Preliminary results indicate that autumn (September to November) is the only season in which EDW is simulated by the model in both the maximum and the minimum temperature, in all three regions and across all model resolutions. Regional differences emerge in the other seasons: for example, the Tibetan Plateau-Himalayas is the only area in which EDW is detected in winter. As for the analysis of EDW drivers, we identify albedo and downward longwave radiation as being the most important variables for EDW, in all three areas considered and in all seasons. Further these results are robust to changes in model resolution, even though a clearer signal is associated with finer resolutions. We finally use the highest resolution EC-Earth simulations available (˜16 km) to identify what areas, within the three considered mountain ranges, are expected to undergo a significant reduction of snow or ice cover

    Middle Stone Age sites located within the Greater Cape Floristic Region on the South African southern coast have material culture with early evidence for key modern human behaviors such as projectile weaponry, large animal hunting, and symbolic behavior. In order to interpret how and why these changes evolved, it is necessary to understand their ecological context as it has direct relevance to foraging behavior. During periods of lowered sea level, a largely flat and vast expanse of land existed south of the modern coastline, but it is now submerged by higher sea levels. This exposed area, the Paleo-Agulhas Plain, likely created an ecological context unlike anything in the region today, as evidenced by fossil assemblages dominated by migratory ungulates. One hypothesis is that the Paleo-Agulhas Plain supported a migration ecosystem of large grazers driven by summer rainfall, producing palatable forage during summer in the east, and winter rainfall, producing palatable forage during winter in the west. Furthermore, ungulates may have been moving from the coastal plain in the south to the interior north of the Cape Fold Mountains, as observed for elephants in historic times.

    The anatomical relationships of the greater occipital nerve (GON) to the semispinalis capitis muscle (SCM) and the trapezius muscle aponeurosis (TMA) were examined to identify topographic landmarks for use in anesthetic blockade of the GON in occipital neuralgia. The course and the diameter of the GON were studied in 40 cadavers (29 females, 11 males), and the points where it pierced the SCM and the TMA were identified. The course of the GON did not differ between males and females. A left-right difference was detected in the site of the GON in the TMA region but not in the SCM region. The nerve became wider towards the periphery. This may be relevant to entrapment of the nerve in the development of occipital neuralgia. In three cases, the GON split into two branches before piercing the TMA and reunited after having passed the TMA, and it pierced the obliquus capitis inferior muscle in another three cases. The GON and the lesser occipital nerve reunited at the level of the occiput in 80% of the specimens. The occiput and the nuchal midline are useful topographic landmarks to guide anesthetic blockade of the GON for diagnosis and therapy of occipital neuralgia. The infiltration is probably best aimed at the site where the SCM is pierced by the GON.

    Glacier and snow melting is main source of water supply making a large contribution to streamflow of major river basins in the Greater Himalaya region including the Syr Darya, the Amu Darya, the Indus, the Ganges and the Brahmaputra basins. Due to the critical role of glacier and snow melting as water supply for both food production and hydropower generation in the region (especially during the low flow season), it is important to evaluate the vulnerability of snow and glacier melting streamflow to different climate conditions. In this study, a distributed glacio-hydrologic model with high resolution climate input is developed and calibrated that explicitly simulates all major hydrological processes and the glacier and snow dynamics for area further discretized by elevation bands. The distributed modeling structure and the glacier and snow modules provide a better understanding about how temperature and precipitation alterations are likely to affect current glacier ice reserves. Climate stress test is used to explore changes in the total streamflow change, snow/glacier melting contribution and glacier accumulation and ablation under a variety of different temperature and precipitation conditions. The latest future climate projections provided from the World Climate Research Programme's Coupled Model Intercomparison Project Phase 5 (CMIP5) is used to inform the possibility of different climate conditions.

Alternatively, ungulates may have been moving from the coastal plain in the south to the interior north of the Cape Fold Mountains, as observed for elephants in historic times. In this study, we assess ungulate movement patterns with inter- and intra-tooth enamel samples for strontium isotopes in fossil fauna from Pinnacle Point sites PP13B and PP30. To accomplish our goals we created a bioavailable 87Sr/86Sr isoscape for the region by collecting plants at 171 sampling sites and developing a geospatial model. The strontium isotope results indicate that ungulates spent most of their time on the Paleo-Agulhas Plain and avoided dissected plain, foothill, and mountain habitats located more than about 15 km north of the modern coastline. The results clearly exclude a north-south (coastal-interior) movement or migration pattern, and cannot falsify the east-west movements hypothesized in the south coast migration ecosystem hypothesis.

  18. Incorporating Medium-Range Weather Forecasts in Seasonal Crop Scenarios over the Greater Horn of Africa to Support National/Regional/Local Decision Makers

    The USAID's Famine Early Warning Systems Network (FEWS NET) provides seasonal assessments of crop conditions over the Greater Horn of Africa (GHA) and other food insecure regions. These assessments and current livelihood, nutrition, market conditions and conflicts are used to generate food security scenarios that help national, regional and local decision makers target their resources and mitigate socio-economic losses. Among the various tools that FEWS NET uses is the FAO's Water Requirement Satisfaction Index (WRSI). The WRSI is a simple yet powerful crop assessment model that incorporates current moisture conditions (at the time of the issuance of forecast), precipitation scenarios, potential evapotranspiration and crop parameters to categorize crop conditions into different classes ranging from "failure" to "very good". The WRSI tool has been shown to have a good agreement with local crop yields in the GHA region. At present, the precipitation scenarios used to drive the WRSI are based on either a climatological forecast (that assigns equal chances of occurrence to all possible scenarios and has no skill over the forecast period) or a sea-surface temperature anomaly based scenario (which at best have skill at the seasonal scale). In both cases, the scenarios fail to capture the skill that can be attained by initial atmospheric conditions (i.e., medium-range weather forecasts). During the middle of a cropping season, when a week or two of poor rains can have a devastating effect, two weeks worth of skillful precipitation forecasts could improve the skill of the crop scenarios. With this working hypothesis, we examine the value of incorporating medium-range weather forecasts in improving the skill of crop scenarios in the GHA region. We use the NCEP's Global Ensemble Forecast system (GEFS) weather forecasts and examine the skill of crop scenarios generated using the GEFS weather forecasts with respect to the scenarios based solely on the climatological forecast

    Current aerobiological research applies the hypothesis that the main source of atmospheric birch (Betula) pollen is forest trees. Our results indicate that the measured levels in Copenhagen are not only due to birch trees in Danish forests but that the urban areas also seem to be a significant source of birch pollen. A number of episodes in 2003 with enhanced pollen levels in Copenhagen seem to be associated with parks and gardens inside and just outside the city. Our results also indicate one long-range transport episode from remote sources in Poland and Germany. Finally, our results show that the pollen levels vary considerably over the day and geographically between Copenhagen and the city of Roskilde, 40 km away. We suggest, that these differences in time and space in the pollen levels are mapped using an integrated monitoring strategy.

    Originally defined as "tenderness to palpation over the greater trochanter with the patient in the side-lying position," greater trochanteric pain syndrome (GTPS) as a clinical entity, has expanded to include a number of disorders of the lateral, peritrochanteric space of the hip, including trochanteric bursitis, tears of the gluteus medius and minimus and external coxa saltans (snapping hip). Typically presenting with pain and reproducible tenderness in the region of the greater trochanter, buttock, or lateral thigh, GTPS is relatively common, reported to affect between 10% and 25% of the general population. Secondary to the relative paucity of information available on the diagnosis and management of components of GTPS, the presence of these pathologic entities may be underrecognized, leading to extensive workups and delays in appropriate treatment. This article aims to review the present understanding of the lesions that comprise GTPS, discussing the relevant anatomy, diagnostic workup and recommended treatment for trochanteric bursitis, gluteus medius and minimus tears, and external coxa saltans.

    Human cases of American cutaneous leishmaniasis (ACL) have been recorded in Serra da Cantareira, in the Greater São Paulo Metropolitan Region, where two conservation units are situated, the Parque Estadual da Cantareira and the Parque Estadual Alberto Löfgren. The present study aimed to identify the sandfly fauna and some of its ecological aspects in these two parks and their surrounding area to investigate Leishmania sp. vectors. The captures were undertaken monthly from January to December 2009, from 6:00 p.m. to 6:00 a.m., with automatic light traps installed in forests and peridomicile areas and with modified black/white Shannon traps in the peridomicile. A total of 12 species and 5,436 sandflies were captured: with automatic light traps (141), Shannon traps (5,219) and attempting to bite the researchers while they were conducting the collection in Shannon traps (76). Pintomyia fischeri and Migonemyia migonei were the most abundant species. Pi. fischeri predominated in all three kinds of captures (49%, 88.8% and 65.8%, respectively). Mg. migonei was the second most prevalent in Shannon traps (10.0%) and attempting to bite the researchers (22.4%). Pi. fischeri females were significantly more attracted to black and those of Mg. migonei to white Shannon traps. A positive and significant correlation was observed between the numbers of Pi. fischeri and the mean of minimum relative humidity values on the fifteen days prior to capture, while there was a negative and significant correlation between the relative humidity on the capture day and the two most abundant species. The anthropophilia and high frequencies of Pi. fischeri and Mg. migonei suggest that both species may be transmitting ACL agents in this region.

    Environmental life-cycle assessment (LCA) was applied to evaluate three different water systems of the water sector in Copenhagen, Denmark, including technologies within water supply, facilities recycling water and treatment of sewer overflow. In these three water systems LCA was used to evaluate the environmental impacts of each of the processes involved. The overall conclusion was that LCA is suitable as a decision support tool in the water sector as it provides a holistic evaluation platform of the considered alternatives categorised in environmental impact categories. The use of LCA in the water sector of this region has limitations since it does not yet consider impact categories assessing freshwater scarcity and ecological sustainability.

    The accurate classification and mapping of individual trees at species level in the savanna ecosystem can provide numerous benefits for the managerial authorities. Such benefits include the mapping of economically useful tree species, which are a key source of food production and fuel wood for the local communities, and of problematic alien invasive and bush encroaching species, which can threaten the integrity of the environment and livelihoods of the local communities. Species level mapping is particularly challenging in African savannas which are complex, heterogeneous, and open environments with high intra-species spectral variability due to differences in geology, topography, rainfall, herbivory and human impacts within relatively short distances. Savanna vegetation are also highly irregular in canopy and crown shape, height and other structural dimensions with a combination of open grassland patches and dense woody thicket - a stark contrast to the more homogeneous forest vegetation. This study classified eight common savanna tree species in the Greater Kruger National Park region, South Africa, using a combination of hyperspectral and Light Detection and Ranging (LiDAR)-derived structural parameters, in the form of seven predictor datasets, in an automated Random Forest modelling approach. The most important predictors, which were found to play an important role in the different classification models and contributed to the success of the hybrid dataset model when combined, were species tree height; NDVI; the chlorophyll b wavelength (466 nm) and a selection of raw, continuum removed and Spectral Angle Mapper (SAM) bands. It was also concluded that the hybrid predictor dataset Random Forest model yielded the highest classification accuracy and prediction success for the eight savanna tree species with an overall classification accuracy of 87.68% and KHAT value of 0.843.

    Gastrointestinal infection due to intestinal parasites is an enormous health problem in developing countries and its reliable diagnosis is demanding. Therefore, this study aimed at evaluating a commercially available immunochromatographic assay (ICA) for the detection of cryptosporidia, Giardia duodenalis, and Entamoeba histolytica/dispar for its usefulness in the Greater Cairo Region, Egypt. Stool samples of 104 patients who presented between October 2012 and March 2013 with gastrointestinal symptoms or for the exclusion of parasites at Kasr-Al-Ainy University Medical School were examined by light microscopy of wet mounts and the triple ICA. Microscopy revealed in 20% of the patients [95% confidence interval (CI), 13.5-29.0%] parasites with Hymenolepis nana, E. histolytica/dispar and Blastocystis hominis being the most frequent ones, but was not able to detect G. duodenalis and cryptosporidia, whereas ICA was positive in 21% (95% CI, 14.3-30.0%) and detected E. histolytica/dispar in 12.5% (95% CI, 7.3-20.4%), cryptosporidia in 6.7% (95% CI, 3.1-13.5%) and G. duodenalis in 15.4% (95% CI, 9.6-23.6%) of the patients. Detection of one or more pathogens was associated with access to water retrieved from a well or pump (p = 0.01). Patients between 20 and 29 years of age (p = 0.08) and patients with symptoms of 5 days or longer (p = 0.07) tended to have a higher risk to be infected than patients of other age groups or with shorter-lasting symptoms. In conclusion, the ICA was easy to perform and timesaving. Importantly, it enabled the detection of cryptosporidia, which cannot be found microscopically in unstained smears, demonstrated a higher sensitivity for the detection of G. duodenalis than microscopy, and was more specific for distinguishing E. histolytica/dispar from apathogenic amoeba.

    During the process of malaria elimination in the Greater Mekong Sub-region, mobile and migrant populations (MMPs) have been identified as the most at-risk demographic. An important sub-group of MMPs are seasonal workers, and this paper presents an evaluation of the reach and effectiveness of interventions tailored towards this group and was carried out as part of the Containment Project from 2009-11. A mixed-methods study was conducted in Pailin Province in Western Cambodia. Three-hundred-and-four seasonal workers were surveyed using a structured questionnaire. Qualitative data were gathered through a total of eight focus group discussions and 14 in-depth interviews. Data triangulation of the qualitative and quantitative data was used during analysis. High mobility and low access of the target population to the interventions, as well as lack of social and anthropological research that led to implementation oversights, resulted in under-exposure of seasonal workers to interventions. Consequently, their reach and impact were severely limited. Some services, particularly Mobile Malaria Workers, had the ability to significantly impact key factors, such as risky behaviours among those they did reach. Others, like Listening and Viewing Clubs and mass media campaigns, showed little impact. There is potential in two of the interventions assessed, but high mobility and inadequate exposure of seasonal workers to these interventions must be considered in the development and planning of future interventions to avoid investing in low-impact activities and ensure that all interventions perform according to their maximum potential. This will be critical in order for Cambodia to achieve its aim of malaria elimination. The lessons learned from this study can be extrapolated to other areas of health care in Cambodia and other countries in order to reduce the gap between healthcare provided to MMPs, especially seasonal workers, and to the general population.

    Atmospheric rivers (ARs) are strongly linked to extreme winter precipitation events in the Western U.S., accounting for 80 percent of extreme floods in the Sierra Nevada and surrounding lowlands. In 2010, the U.S. Geological Survey developed the ARkStorm extreme storm scenario for California to quantify risks from extreme winter storms and to allow stakeholders to better explore and mitigate potential impacts. To explore impacts on natural resources and communities in montane and adjacent environments, we downscaled the scenario to the greater Lake Tahoe, Reno and Carson City region of northern Nevada and California. This ArkStorm@Tahoe scenario was presented at six stakeholder meetings, each with a different geographic and subject matter focus. Discussions were facilitated by the ARkStorm@Tahoe team to identify social and ecological vulnerabilities to extreme winter storms, science and information needs, and proactive measures that might minimize impacts from this type of event. Information collected in these meetings was used to develop a tabletop emergency response exercise and set of recommendations for increasing resilience to extreme winter storm events in both Tahoe and the downstream communities of Northern Nevada.Over 300 individuals participated in ARkStorm@Tahoe stakeholder meetings and the emergency response exercise, including representatives from emergency response, natural resource and ecosystem management, health and human services, public utilities, and businesses. Interruption of transportation, communications, and lack of power and backup fuel supplies were identified as the most likely and primary points of failure across multiple sectors and geographies, as these interruptions have cascading effects on natural and human systems by impeding emergency response efforts. Other key issues that arose in discussions included contamination risks to water supplies and aquatic ecosystems, especially in the Tahoe Basin and Pyramid Lake, interagency

    The purpose of this survey was to investigate the small-area variations in low birthweight within social services districts in Copenhagen and the relation of such variations to the socioeconomic characteristics of the district. The study was based on register data and included all live-born single on births to women living in the city of Copenhagen from 1987-90. We found a statistically significant association between district and risk of newborns being small-for-gestational age (SGA). This association was independent of adjustment for maternal age and parity. Only part of the association was explained, though this was still significant, using an index summarizing the socioeconomic living conditions in the district. Splitting up the index into its four constituent components, however, showed that the association between SGA and district was primarily due to housing conditions in the districts. Mapping the districts demonstrated a clear tendency of clustering of the high-risk areas with poor socioeconomic conditions.

    Prolongation of the PR interval has been associated with an increased risk of incident atrial fibrillation (AF). To determine if there was a nonlinear relation between PR interval duration and the risk of AF. We included 288,181 individuals, corresponding to one third of the population in the greater region of Copenhagen. These individuals had a digital electrocardiogram (ECG) recorded in a general practitioner's core facility from 2001 to 2010. Data on drug use, comorbidity, and outcomes were collected from Danish registries. During a median follow-up period of 5.7 years, 11,087 developed AF. Having a PR interval ≥95th percentile (≥196 ms for women, ≥204 ms for men) was associated with an increased risk of AF as evidenced by a multivariable-adjusted hazard ratio (HR) of 1.18 (95% confidence interval [CI] 1.06-1.30, P = .001) for women and 1.30 (1.17-1.44, P < .001) for men compared with the respective reference groups (PR interval between 40th and 60th percentile). Having a short PR interval <5th percentile (≤121 ms for women, ≤129 ms for men) was also associated with an increased risk of AF for women (HR 1.32, 95% CI 1.12-1.56, P = .001), but this was not significant for men (HR 1.09, 95% CI 0.92-1.29, P = .33). In this large ECG study, we found an increased risk of AF for longer PR intervals for both women and men. With respect to short PR intervals, we also observed an increased risk of AF for women.

    2006-03-15

    Purpose: Our aim was to determine the dose to the clinical target volume (CTV) required for solitary extramedullary plasmacytoma (EMP) in the head and neck (HN). Methods and Materials: Seventeen patients (15 Stage I and 2 Stage II) were treated for HN EMP at our institution between 1979 and 2003. The mean International Commission on Radiation Units (ICRU) dose prescribed to the CTV was 52.6 Gy (range, 40-65 Gy) over 24 fractions (range: 20-30). The Stage II patients received neck irradiation doses of 40 and 60 Gy. A mean dose of 36.4 Gy was used for 5 Stage I patients who received elective neck irradiation. Dose administrated to the CTV was evaluated from dosimetric data or from planning films when dosimetric data were not available. Two groups of patients were distinguished: CTV covered with a dose greater than 40 Gy and CTV covered with a dose greater than 45 Gy. Results: The 5-year local control was 72.8%. It was 100% for patients who received dose to the CTV {<=} 45 Gy vs. 50% for dose to the CTV <45 Gy (p = 0.034). The prognostic factor for 5-year disease-specific survival (81.6%) was local control (p = 0.058). The prognostic factors for disease-free survival (64.1%) were monoclonal immunoglobulin secretion (p = 0.008) and a CTV dose {<=} 45 Gy (p = 0.056) Conclusions: Local control of EMP in the HN seems to be improved when the dose to the CTV is {<=} 45 Gy. A minimum dose of 45 Gy should be recommended to the CTV.

  19. Synchronous climate-driven regime shifts at the onset of the Holocene inferred from diatom records in lakes of the Greater Yellowstone region

    Diatom records covering the late-glacial and early Holocene periods were recovered from three lakes in different areas of Yellowstone National Park to investigate the impacts of large-scale climatic change on aquatic ecosystem evolution following deglaciation. All lakes show synchronous diatom community shifts from the dominance of tychoplanktic Fragilaria species to benthic species in the interval of 11,300-11500 cal yr BP, indicating a regional decrease in effective moisture. The synchroneity of changes in diatom community structure suggests the influence of overlying large-scale climatic change on lacustrine ecosystems. A major shift in the same interval also is evident in other proxy records, such as pollen and charcoal, throughout the Yellowstone region at the late-glacial/early-Holocene transition. This suggests that the summer insolation maximum induced a widespread and rapid reorganization of ecosystem structure and function.

    The problems of processing and interpreting the data provided by radar satellite interferometry for the conditions of landslides covered by vegetation are analyzed in two case studies of landslides in the Northern Caucasus in the region of Kepsha and Mamaika villages in the vicinity of the railway tunnels. The estimates of the displacement fields are obtained by the method of persistent scatterers using the StaMPS program package. The five-year experience of landslide monitoring shows that in the unfavorable conditions of satellite radar interferometry, proper selection of the strategy of satellite image processing is vital. In the present paper, we discuss, in particular, the crop selection, the selection of the master image, reference area, and digital elevation model. For the landslide located in the sparsely populated region near Kepsha village, we used the data from the ascending and descending tracks of the long-wavelength ALOS and shorter-wavelength ENVISAT satellites. For the landslide in the region of Mamaika village with a large number of different buildings serving as good scatterers for radar signals, we used the images from the ENVISAT and from TerraSAR satellite, which transmits even shorter waves. The average line-of-sight (LOS) displacement velocities V LOS for the landslide near Kepsha village measure at most 10 mm per annum, which means that this landslide has remained stable at least since 2004. The landslide in Mamaika village is significantly more active. The average LOS displacement velocities in the active part of this landslide attain 60 mm per annum. The artificial corner reflector installed on the segment of the landslide where natural scatterers of radar signal are absent made it possible to estimate the LOS displacement velocity on this segment of the slope at 49 mm per annum.

    The population of Ghana is increasingly becoming urbanized with about 70 % of the estimated 26.9 million people living in urban and peri-urban areas. Nonetheless, eight out of the ten regions in Ghana remain predominantly rural where only 32.1 % of the national health sector workforce works. Doctor-patient ratio in a predominantly rural region is about 1:18,257 compared to 1:4,099 in an urban region. These rural-urban inequities significantly account for the inability of Ghana to attain the health related Millennium Development Goals (MDGs) before the end of 2015. To ascertain whether or not rural-urban differences exist in health worker motivation levels and quality of health care in health facilities accredited by the National Health Insurance Authority in Ghana. This is a baseline quantitative study conducted in 2012 among 324 health workers in 64 accredited clinics located in 9 rural and 7 urban districts in Ghana. Ordered logistic regression was performed to determine the relationship between facility geographic location (rural/urban) and staff motivation levels, and quality health care standards. Quality health care and patient safety standards were averagely low in the sampled health facilities. Even though health workers in rural facilities were more de-motivated by poor availability of resources and drugs than their counterparts in urban facilities (p < 0.05), quality of health care and patient safety standards were relatively better in rural facilities. For Ghana to attain the newly formulated sustainable development goals on health, there is the need for health authorities to address the existing rural-urban imbalances in health worker motivation and quality health care standards in primary healthcare facilities. Future studies should compare staff motivation levels and quality standards in accredited and non-accredited health facilities since the current study was limited to health facilities accredited by the National Health Insurance Authority.

    The Reading Acceleration Program is a computerized program that improves reading and the activation of the error-detection mechanism in individuals with reading difficulty (RD) and typical readers (TRs). The current study aims to find the neural correlates for this effect in English-speaking 8-12-year-old children with RD and TRs using a functional connectivity analysis. Functional magnetic resonance imaging data were collected during a lexical decision task before and after 4 weeks of training with the program, together with reading and executive functions measures. Results indicated improvement in reading, visual attention, and speed of processing in children with RD. Following training, greater functional connectivity was observed between the left fusiform gyrus and the right anterior cingulate cortex in children with RD and between the left fusiform gyrus and the left anterior cingulate cortex in TRs. The change in functional connectivity after training was correlated with increased behavioral scores for word reading and visual attention in both groups. The results support previous findings of improved monitoring and mental lexicon after training with the Reading Acceleration Program in children with RD and TRs. The differences in laterality of the anterior cingulate cortex in children with RD and the presumable role of the cingulo-opercular control network in language processing are discussed.

    The 'Copenhagen Accord' fails to deliver the political framework for a fair, ambitious and legally-binding international climate agreement beyond 2012. The current climate policy regime dynamics are insufficient to reflect the realities of topical complexity, actor coalitions, as well as financial, legal and institutional challenges in the light of extreme time constraints to avoid 'dangerous' climate change of more than 2°C. In this paper we analyze these stumbling blocks for international climate policy and discuss alternatives in order to regain momentum for future negotiations. PMID:20525341

    Two main goals of the integrated solid waste management system (ISWMS) of Metro Vancouver (MV) include further recycling of waste and energy recovery via incineration of waste. These two very common goals, however, are not always compatible enough to fit in an ISWMS depending on waste characteristics and details of recycling programs. This study showed that recent recycling activities in MV have negatively affected the net heating value (NHV) of municipal solid waste (MSW) in this regional district. Results show that meeting MV's goal for additional recycling of MSW by 2015 will further reduce the NHV of waste, if additional recycling activities are solely focused on more extensive recycling of packaging materials (e.g. paper and plastic). It is concluded that 50% additional recycling of paper and plastic in MV will increase the overall recycling rate to 70% (as targeted by the MV for 2015) and result in more than 8% reduction in NHV of MSW. This reduction translates to up to 2.3 million Canadian dollar (CAD$) less revenue at a potential waste-to-energy (WTE) plant with 500 000 tonnes year(-1) capacity. Properly designed recycling programmes, however, can make this functional element of ISWMS compatible with green goals of energy recovery from waste. Herein an explanation of how communities can increase their recycling activities without affecting the feasibility of potential WTE projects is presented.

    Significant amounts of dust are being transferred on an annual basis over the Mediterranean Basin and continental Europe from Northern Africa (Sahara Desert) and Middle East (Arabian Peninsula) as well as from other local sources. Dust affects a number of processes in the atmosphere modulating weather and climate also having an impact on human health and the economy. Therefore, the ability of simulating adequately the amount and optical properties of dust is essential. This work focuses on the evaluation of the MACC reanalysis dust product over the regions mentioned above. The evaluation procedure is based on pure dust satellite retrievals from CALIOP/CALIPSO that cover the period 2007-2012. The CALIOP/CALIPSO data utilized here come from an optimized retrieval scheme that was originally developed within the framework of the LIVAS (Lidar Climatology of Vertical Aerosol Structure for Space-Based LIDAR Simulation Studies) project. CALIOP/CALIPSO dust extinction coefficients and dust optical depth patterns at 532 nm are used for the validation of MACC natural aerosol extinction coefficients and dust optical depth patterns at 550 nm. Overall, it is shown in this work that space-based lidars may play a major role in the improvement of the MACC aerosol product. This research has been financed under the FP7 Programme MarcoPolo (Grand Number 606953, Theme SPA.2013.3.2-01).

    Michael Frayn's highly acclaimed play "Copenhagen", which reenacts the 1941 visit by Werner Heisenberg to Niels Bohr in Nazi-occupied Copenhagen, has now closed after a production in New York that won a Pulitzer Prize, and a successful tour of many cities in the US. Symposia in New York, Washington, Cambridge, Pasadena, and Raleigh have presented the science - quantum mechanics and nuclear physics - that undergirds the play, have debated its historical accuracy, and have celebrated its theatrical realization. The play, the symposia, and recently released documents have led to a new and heightened debate about old questions, among them why Heisenberg visited Bohr, what went on during their uncongenial meeting, and why the Germans did not succeed in building an atomic bomb. This in turn has resulted in a plethora of sometimes polemical articles in journals and magazines, that try to answer the questions. In this talk I will review some of the evidence, in particular about the German failure to make a bomb. While I will concentrate on the physics, the "political" factors will also be adumbrated.

    The northern Caribbean margin underwent arc-continent collision in the late Cretaceous and Paleogene. On Cuba this les to the stacking of tectonic slices that comprise from top to bottom a volcanic arc unit, an ophiolite complex, a deformed belt of sedimentary rocks (the Camajuaní and Placetas belts) and finally rocks correlative to the Bahamas platform on the southern North American continental margin. On south-central and western Cuba, HP-LT metasedimentary rocks, on the Isle of Pines including a HT-LP overprint, were exhumed in the course of the late Cretaceous, probably at least partly added by extensional unroofing. These metamorphic rocks are exhumed in tectonic windows in the ophiolite and volcanic arc tectonic slices. Their exhumation quite surprisingly coincided with the arrest in arc volcanism in the Cuban periphery. Here, we present an integrated structural geological and stratigraphic study of the sedimentary units incorporated in the basal parts and underlying the ophiolite unit in the Camagüey province in northern central Cuba. Aim of this study was to constrain the direction and timing of compressional deformation contemporaneous with and following the exhumation and possibly extension in the southern internal parts of the Cuban fold-and thrust belt, and with the arrest in arc volcanism. Our results indicate that the Placetas belt in the Camagüey region consist of tightly, polyphase folded deep marine upper Jurassic to upper Cretaceous limestones, forming isolated blocks incorporated in a tectonic mélange at the base of the ophiolite unit. Timing of their deformation is likely late Cretaceous and younger. The Bahamas platform-related carbonates in the Sierra de Cubitas at the base of the Cuban nappe stack are characterized by a single, open folding phase trending sub-parallel to the main NW-SE trending structural grain of the fold- and thrust belt. This deformation marks the arrest in emplacement of the Cuban nappe stack onto the southern North

    As the global population becomes increasingly urbanized, spatially concentrated centres of anthropogenic CO2 and other greenhouse gases (GHG) arise. While mitigation measures exist at national and international scales, their implementation will be more effective if linked to the urban-scale of the sources. Routine top-down approaches that quantify emissions of GHG from cities and megacities are needed to understand the dynamics of the urban carbon cycle to eventually define relevant policy decisions. London is the biggest urban conurbation in Western Europe with more than 8 million inhabitants. It emitted roughly 45000 ktn CO2 in 20101. To understand the carbon dynamics and quantify anthropogenic emissions from London, airborne surveys of atmospheric CO2, O3, particles and meteorological variables were carried out over the city, onboard the NERC-ARSF Dornier-228 UK research aircraft. We applied an Integrative Mass Boundary Layer method (IMBL) using airborne CO2 observations obtained in horizontal transects crossing London at 360 m at different times of the day and by sampling upwind-downwind profiles. IMBL CO2 fluxes were compared to an emissions inventory and neighbourhood-scale eddy-covariance fluxes in central London. Daytime fluxes in October 2011 from the IMBL calculations ranged from 46 to 104 μmolCO2 m-2 s-1 and covered 30-70% of the urban region. The IMBL CO2 fluxes were the same order of magnitude as observed eddy-covariance fluxes and were statistically comparable to the emission inventory for the same footprint area. A sensitivity analysis suggested that horizontal variability of the CO2 field in the urban mixing layer is the most critical factor affecting IMBL fluxes. The determination of the boundary height and vertical wind speed had more impact on fluxes calculated from upwind-downwind profiles. Furthermore, low-altitude airborne measurements of CO2 provide the advantage of direct observation of the CO2 urban dome of a megacity and relate the

    Industrialization including the effects of expanding energy consumption and metallurgy production as well as population growth and demographic pressure increased heavy-metal pollution loads progressively since the Industrial Revolution. Especially the burning of fossil fuels mobilizes heavy metals like lead and zinc on a large scale. By wet and dry deposition, these loads end up in the aquatic environment where sediments serve as sinks for these contaminations. In this study, we examine the pollution history of Copenhagen, Denmark. A sediment core was retrieved for the lake in the Botanical Gardens in central Copenhagen using a rod-operated piston corer. The water body used to be part of the old town's defence-wall system and was turned into a lake by terrain levelling in the mid 17th century. After initial X-ray fluorescence core scanning, element concentrations were determined using emission spectroscopy. The onset of gyttja accumulation in the lake is assumed to start immediately after the construction of the fortification in approximately AD 1645. An age model representing the last approximately 135 years for the uppermost 60cm was established by lead-210 and cesium-137 dating. The older part was dated via recognition of markedly increased levels of levoglucosan which are interpreted to be linked with recorded fires in Copenhagen. Similarly, two distinct layers interstratify the sediment column and mark pronounced increases of minerogenic material inflow which can be linked to known historical events. Significant pollution load increases are evident from the 1700s along with urban growth and extended combustion of carbon carriers fuels such as wood and coals. However, a more pronounced increase in lead and zinc deposition only begins by the mid-19th century. Maxima for the latter two pollutants are reached in the late 1970s followed by a reduction of emissions in accordance with stricter environmental regulations. Here, especially the phasing-out of tetraethyl

    In a new approach the odour emissions from aircraft engines at Copenhagen Airport are calculated using actual fuel flow and emission measurements (one main engine and one APU: Auxiliary Power Unit), odour panel results, engine specific data and aircraft operational data for seven busy days. The calculation principle assumes a linear relation between odour and HC emissions. Using a digitalisation of the aircraft movements in the airport area, the results are depicted on grid maps, clearly reflecting aircraft operational statistics as single flights or total activity during a whole day. The results clearly reflect the short-term temporal fluctuations of the emissions of odour (and exhaust gases). Aircraft operating at low engine thrust (taxiing, queuing and landing) have a total odour emission share of almost 98%, whereas the shares for the take off/climb out phases (2%) and APU usage (0.5%) are only marginal. In most hours of the day, the largest odour emissions occur, when the total amount of fuel burned during idle is high. However, significantly higher HC emissions for one specific engine cause considerable amounts of odour emissions during limited time periods. The experimentally derived odour emission factor of 57 OU/mg HC is within the range of 23 and 110 OU/mg HC used in other airport odour studies. The distribution of odour emission results between aircraft operational phases also correspond very well with the results for these other studies. The present study uses measurement data for a representative engine. However, the uncertainties become large when the experimental data is used to estimate the odour emissions for all aircraft engines. More experimental data is needed to increase inventory accuracy, and in terms of completeness it is recommended to make odour emission estimates also for engine start and the fuelling of aircraft at Copenhagen Airport in the future.

  11. The Kantian element in the Copenhagen interpretation of quantum mechanics

    NASA Astrophysics Data System (ADS)

    Cale, David Lee

    In Quantum Physics and the Philosophical Tradition, Aage Petersen makes the troubling claim that the entirety of the tradition of Western philosophy is "deconstructed" by quantum mechanics. This viewpoint applies, especially, to the relationship between Kantian philosophy and quantum theory. It is generally accepted that quantum mechanics, in its Copenhagen interpretation, has destroyed all validity for the classical belief in a deterministic underlying reality, a belief sustained throughout the nineteenth century through a philosophical ground in Kant's critical philosophy. This dissertation takes on the daunting task of determining what, if any, relationship can be had between contemporary physics and Kantian philosophy. It begins with a historical review of the challenges posed for Kant's arguments and proposed solutions, especially those offered by Cassirer. It then turns to the task of providing the Western philosophical tradition with an interpretation apart from Petersen's, which sees it as concerned only with the problem of being. The offered solution is the suggestion that Western philosophy be understood as a struggle, between epistemological and ontological perspectives, to provide a context for the various descriptions of nature provided by human scientific progress. Kant's philosophy is then interpreted as an effort to provide Newtonian physics with a valid context in the face of Hume's skepticism. The finding is that Kant was the first to suggest that an object does not acquire the spatio-temporal properties used in its physical description until introduced to an observer. The dissertation concludes that the authors of the Copenhagen interpretation were essentially engaged in Kant's enterprise through their attempt to provide an observer based context for the spatio-temporal descriptive principles used in the physics of their time.

    OBJECTIVE: To evaluate the safety of the intradermal Copenhagen BCG vaccine in neonates at different levels of delivery and neonatal units of the Durban Functional Region and surrounding regions. METHODS: A prospective study was carried out over a two-year period between July 1997 and June 1999. All neonates who had been vaccinated with the intradermal vaccine were evaluated at immunization clinics six weeks after immunization, or earlier if adverse effects occurred. FINDINGS: In total, 9763 neonates were examined: in 95.4% the vaccination scar had healed and 1.5% had no visible scar. Adverse events occurred in 3.1%. The proportion of neonates with no visible vaccination scars decreased over the study period, as did the number with adverse events. The lowest rate of adverse events and the highest rates of healed vaccination scars were seen in the tertiary hospital and regional and district hospitals that were in close proximity to the academic centre involved in this study. CONCLUSIONS: In the study sites, the transition from the percutaneous to intradermal route of administration of BCG vaccine was successful and took place without incurring unacceptably high rates of adverse events. To minimize adverse events, however, it is essential to continue training health personnel involved in implementing intradermal BCG vaccination programmes. PMID:11357213

    The FIFA 11+ was developed as a complete warm-up program to prevent injuries in soccer players. Although reduced hip adduction strength is associated with groin injuries, none of the exercises included in the FIFA 11+ seem to specifically target hip adduction strength. To investigate the effect on eccentric hip adduction strength of the FIFA 11+ warm-up program with or without the Copenhagen adduction exercise. Randomized controlled trial; Level of evidence, 1. We recruited 45 eligible players from 2 U19 elite male soccer teams. Players were randomized into 2 groups; 1 group carried out the standard FIFA 11+ program, while the other carried out the FIFA 11+ but replaced the Nordic hamstring exercise with the Copenhagen adduction exercise. Both groups performed the intervention 3 times weekly for 8 weeks. Players completed eccentric strength and sprint testing before and after the intervention. Per-protocol analyses were performed, and 12 players were excluded due to low compliance (<67% of sessions completed). The main outcome was eccentric hip adduction strength (N·m/kg). Between-group analyses revealed a significantly greater increase in eccentric hip adduction strength of 0.29 Nm/kg (8.9%; P = .01) in favor of the group performing the Copenhagen adduction exercise, whereas no within-group change was noted in the group that used the standard FIFA 11+ program (-0.02 N·m/kg [-0.7%]; P = .69). Including the Copenhagen adduction exercise in the FIFA 11+ program increases eccentric hip adduction strength, while the standard FIFA 11+ program does not.

    In the 1960s and 1970s Turkish workers migrated to Denmark, as well as other Western European countries, in pursuit of work. The first Turkish immigrants to Denmark from this period are now beginning to enter the ranks of the elderly. They have not returned home and their families have joined them and settled in Denmark. The question arises as to how they will live out their old age in their new country. This article addresses the social situation of the elderly Turkish immigrants in Copenhagen. An interview study of Turkish immigrants 55 years and older showed that their situation had not changed appreciably in the past decade as regards a number of economic and social variables such as housing. This article analyzes the results of the survey, and suggests some ways of interpreting them, both in terms of theories of modernization and assimilation, and aging as leveler or as a double jeopardy. jg]Key words gw]Migration gw]Elderly immigrants gw]Living conditions gw]Social conditions gw]Denmark gw]Turkish immigrants.

    Hans Christian Oersted is mostly known as the discoverer of electromagnetism and for being one of the physicists who were deeply influenced and fascinated by the romantic natural philosophy. In this article another side of Oersted is presented. What is underestimated until now is Oersted's contribution to the research of geomagnetism. Oersted stood in close contact with Carl Friedrich Gauss and Wilhelm Weber, whom he visited in 1834 in Göttingen. Oersted's aim was to learn the new developments in geomagnetism. Afterwards he was crucial in the building of a new magnetic observatory in Copenhagen as well as a second one with better equipment. Oersted formed a huge team for magnetic observations and the gathered data were sent to Gauss and Weber who published them. The correspondence between Oersted, Gauss and Weber was mostly dedicated to the transmission of these data, details about instruments and the best way of building a magnetic observatory. Unfortunately, Gauss and Weber had to stop their very successful collaboration in 1843, because Weber belonged to the Göttingen Seven and later on Oersted stopped his observations, because he had lost his partners in this research project.

  18. Needle traits of an evergreen, coniferous shrub growing at wind-exposed and protected sites in a mountain region: does Pinus pumila produce needles with greater mass per area under wind-stress conditions?

    Snow depth is one of the most important determinants of vegetation, especially in mountainous regions. In such regions, snow depth tends to be low at wind-exposed sites such as ridges, where stand height and productivity are limited by stressful environmental conditions during winter. Siberian dwarf pine (Pinus pumila Regel) is a dominant species in mountainous regions of Japan. We hypothesized that P. pumila produces needles with greater mass per area at wind-exposed sites than at wind-protected sites because it invests more nitrogen (N) in cell walls at the expense of N investment in the photosynthetic apparatus, resulting in increased photosynthetic N use efficiency (PNUE). Contrary to our hypothesis, plants at wind-exposed site invested less resources in needles, as exhibited by lower biomass, N, Rubisco and cell wall mass per unit area, and had higher photosynthetic capacity, higher PNUE and shorter needle life-span than plants at a wind-protected site. N partitioning was not significantly different between sites. These results suggest that P. pumila at wind-exposed sites produces needles at low cost with high productivity to compensate for a short leaf life-span, which may be imposed by wind stress when needles appear above the snow surface in winter.

    The Copenhagen problem where the primaries of equal masses are magnetic dipoles is used in order to determine the Newton-Raphson basins of attraction associated with the equilibrium points. The parametric variation of the position as well as of the stability of the Lagrange points are monitored when the value of the ratio $\\lambda$ of the magnetic moments varies in predefined intervals. The regions on the configuration $(x,y)$ plane occupied by the basins of convergence are revealed using the multivariate version of the Newton-Raphson iterative scheme. The correlations between the basins of attraction of the libration points and the corresponding number of iterations needed for obtaining the desired accuracy are also illustrated. We perform a thorough and systematic numerical investigation by demonstrating how the dynamical quantity $\\lambda$ influences the shape, the geometry and also the degree of fractality of the attracting domains. Our numerical results strongly indicate that the ratio $\\lambda$ is indeed a very influential parameter in the electromagnetic binary system.

    Crowding in the emergency department (ED) is a well-known problem resulting in an increased risk of adverse outcomes. Effective triage might counteract this problem by identifying the sickest patients and ensuring early treatment. In the last two decades, systematic triage has become the standard in ED's worldwide. However, triage models are also time consuming, supported by limited evidence and could potentially be of more harm than benefit. The aim of this study is to develop a quicker triage model using data from a large cohort of unselected ED patients and evaluate if this new model is non-inferior to an existing triage model in a prospective randomized trial. The Copenhagen Triage Algorithm (CTA) study is a prospective two-center, cluster-randomized, cross-over, non-inferiority trial comparing CTA to the Danish Emergency Process Triage (DEPT). We include patients ≥16 years (n = 50.000) admitted to the ED in two large acute hospitals. Centers are randomly assigned to perform either CTA or DEPT triage first and then use the other triage model in the last time period. The CTA stratifies patients into 5 acuity levels in two steps. First, a scoring chart based on vital values is used to classify patients in an immediate category. Second, a clinical assessment by the ED nurse can alter the result suggested by the score up to two categories up or one down. The primary end-point is 30-day mortality and secondary end-points are length of stay, time to treatment, admission to intensive care unit, and readmission within 30 days. If proven non-inferior to standard DEPT triage, CTA will be a faster and simpler triage model that is still able to detect the critically ill. Simplifying triage will lessen the burden for the ED staff and possibly allow faster treatment. Clinicaltrials.gov: NCT02698319 , registered 24. of February 2016, retrospectively registered.

    AbstractThe aim of the present study was to assess the frequency of intestinal parasitic infection among patients with gastrointestinal tract disorders from the Greater Cairo region, Egypt. In addition, a comparison was made of the accuracy of direct thin and thick smear, formol-ether sedimentation (FEC), centrifugal flotation (CF), and mini-FLOTAC techniques in the diagnosis of infection. Out of 100 patients, the overall prevalence of parasitic infection was 51%. Only 6% had dual infection. Giardia lamblia was the most common parasite (26%), followed by Hymenolepis nana (20%), Entamoeba coli (8%), and Enterobius vermicularis (3%). Except the statistically significant association between E. vermicularis infection and perianal itching and insomnia (P < 0.001), age, gender, and complaints of the examined individuals had no association with prevalence of parasitic infection. Both FEC and CF were equally the most accurate techniques (accuracy = 98.2%, confidence interval [CI] = 0.95-1.0, and κ index = 0.962), whereas the Kato-Katz method was the least accurate (accuracy = 67.5%, CI = 0.57-0.78, and κ index = 0.333). However, mini-FLOTAC-ZnSO4 was the most accurate for diagnosis of helminthic infection, and FEC was more accurate for diagnosis of protozoal infection (accuracy = 100%, CI = 1.0-1.0, and κ index = 1).

    Limited knowledge of the subsurface geology motivates the use of geophysical techniques before large engineering projects are conducted. These applications are normally restricted to satisfy the project aims, like mapping the near surface sediments, unconsolidated rocks and/or geological structures that may affect the construction locally. However, the applications can also contribute to the general knowledge of the regional geology around the location of interest. This report highlights the mapping of a buried Quaternary valley and identification of regional faults by a reflection and refraction seismic survey performed in Copenhagen. A 13.9 Km seismic survey was carried out at Copenhagen city along six crooked lines in order to determine the velocity fields in the near subsurface segment of a planned metro line and reflection patterns in deeper levels. The aim of the survey was to collect information needed for designing the underground metro. In particular it was sought to map the interface between Quaternary sedimentary layers of clay, till and sand, and the underlying layers of Palaeogene limestone found between 7 and 40 m below the ground surface. The data acquisition was carried out using a 192 channels array, receiver groups with 5 m spacing and a Vibroseis as a source at 5 m spacing following a roll along technique to complete the survey spreads. The urban environment demanded extensive survey planning including traffic control, notifications to residents and a fluent coordination with municipal authorities in order to minimize disturbances and ensure data acquisition. The reflection data was processed under a conventional scheme and the refraction data was interpreted using a non-linear traveltime tomography algorithm. The reflection results indicate the presence of faults oriented NW-SE to NNW-SSE affecting the limestone sequences. The faults may be associated to the Sorgenfrei-Tornquist Zone at the transition between the Danish Basin and the Baltic

    Psychosocial risks are now widely recognised as one of the biggest challenges for occupational safety and health (OSH) and a major public health concern. The aim of this paper is to investigate the Portuguese long version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II), in order to analyse the psychometric properties of the instrument and to validate it. The Portuguese COPSOQ II was issued to a total of 745 Portuguese employees from both private and public organisations across several economic sectors at a baseline and then 2 weeks later. Methodological quality appraisal was based on COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) recommendations. An analysis of the psychometric properties of the long version of COPSOQ II (internal consistency, intraclass correlation coefficient, floor and ceiling effects, response rate, missing values, mean and standard deviation, exploratory factor analysis) was performed to determine the validity and reliability of the instrument. The COPSOQ II had a response rate of 60.6% (test) and a follow-up response rate of 59.5% (retest). In general, a Cronbach's alpha of the COPSOQ scales (test and retest) was above the conventional threshold of 0.70. The test-retest reliability estimated by the intraclass correlation coefficient (ICC) showed a higher reliability for most of the scales, above the conventional 0.7, except for eight scales. The proportion of the missing values was less than 1.3%, except for two scales. The average scores and standard deviations showed similar results to the original Danish study, except for eight scales. All of the scales had low floor and ceiling effects, with one exception. Overall, the exploratory factor analysis presented good results in 27 scales assuming a reflective measurement model. The hypothesized factor structure under a reflective model was not supported in 14 scales and for some but not all of these scales the explanation may be a formative

    The purpose of this study was to sonographically compare the early anatomical outcome of a group of clubfeet treated with the Ponseti method (group A, nine clubfeet) with a group treated with an adjustable plexidur splint, the Copenhagen method (group B, 19 feet). The clinical severity was assessed using the Diméglio-Bensahel classification. The need for complementary surgery was clinically assessed at the age of about 2 months. Ultrasound investigation was made in the neonatal period, after 2-3 months of non-surgical treatment and 1-2 months post-surgically. After 2 months of non-surgical treatment the correction obtained at the talo-navicular joint, expressed as the distance between the medial malleolus and the navicular (MM-N distance), was significantly greater in group A. After surgery, tenotomy of the Achilles tendon for all group A feet, and posterior or posteriomedial release for 13 feet in group B, the correction at the talo-navicular and calcaneo-cuboid joints was similar for the two groups. Anatomical correction of the displacement in these joints can be achieved without extensive interventional procedures. Ultrasound may be a valuable tool to assess the effects of different treatment protocols quantitatively.

    After a case of advanced pneumoconiosis occurred in a dental laboratory technician, 31 other dental technicians and 30 control subjects controlled for smoking habits, sex, and age were investigated. More technicians (55%) than controls (30%) had at least grade 1 dyspnoea (p greater than 0.05). Multiple regression analysis showed that 13 technicians who had produced dental prostheses for at least 15 years had consistently lower lung function (FVC, FEV1, FEV1/FVC, MEF50, and DCO single breath), although the differences were not statistically significant. All mean lung function values for technicians and controls were within normal limits. Increases in MEF50 after breathing 80% helium and 20% O2 failed to show small airways dysfunction among the technicians. Of the six with radiological pneumoconiosis (5 simple, 1 advanced) four had symptoms. All three biopsy specimens showed varying degrees of pulmonary fibrosis. DCO single breath was diminished in four of the six. One male dental technician had scleroderma and possibly Erasmus syndrome. Blind readings showed an increased number of suspicious chest x rays films (greater than or equal to category 0/1) among older smokers and ex-smokers (p = 0.013) regardless of occupation. Our results support other evidence that dental technicians are at risk of developing pneumoconiosis. Therefore, adequate hygienic control of dental laboratories is indicated. PMID:3378011

    Climate change will shortly be assuming centre stage when Copenhagen hosts the United Nations Climate Change Conference in early December 2009. In Copenhagen, delegates will discuss the international response to climate change (i.e. the ongoing increase in the Earth's average surface temperature) and the meeting is widely viewed as the most important of its kind ever held (http://en.cop15.dk/). International agreement will be sought on a treaty to replace the 1997 Kyoto Protocol. At the time of writing it is not known whether agreement will be reached on the main issues of reducing greenhouse gas emissions and financing the impacts of climate change, and it appears that the impact of climate change on mental health is unlikely to be on the agenda. We discuss here how climate change could have consequences for global mental health and consider the implications for future research and policy.

    The goal of this research was to estimate the overdiagnosis at the first and second screens of the mammography screening program in Copenhagen, Denmark. This study involves a mammography service screening program in Copenhagen, Denmark, with 35,123 women screened at least once. We fit multistate models to the screening data, including preclinical incidence of progressive cancers and nonprogressive (i.e., overdiagnosed) cancers. We estimated mean sojourn time as 2.7 years (95% confidence interval [CI] 2.2-3.1) and screening test sensitivity as 100% (95% CI 99.8-100). Overdiagnosis was estimated to be 7.8% (95% CI 0.3-26.5) at the first screen and 0.5% (95% CI 0.02-2.1) at the second screen. This corresponds to 4.8% of all cancers diagnosed among participants during the first two invitation rounds and following intervals. A modest overdiagnosis was estimated for the Copenhagen screening program, deriving almost exclusively from the first screen. The CIs were very broad, however, and estimates from larger datasets are warranted.

    Water Sensitive Urban Design (WSUD) is emerging in Denmark. This interdisciplinary desk study investigated the options for WSUD retrofitting in a 15 km(2) combined sewer catchment area in Copenhagen. The study was developed in collaboration with the City of Copenhagen and its water utility, and involved researchers representing hydrogeology, sewer hydraulics, environmental chemistry/economics/engineering, landscape architecture and urban planning. The resulting catchment strategy suggests the implementation of five sub-strategies. First, disconnection is focused within sites that are relatively easy to disconnect, due to stormwater quality, soil conditions, stakeholder issues, and the provision of unbuilt sites. Second, stormwater runoff is infiltrated in areas with relatively deep groundwater levels at a ratio that doesn't create a critical rise in the groundwater table to the surface. Third, neighbourhoods located near low-lying streams and public parks are disconnected from the sewer system and the sloping terrain is utilised to convey runoff. Fourth, the promotion of coherent blue and green wedges in the city is linked with WSUD retrofits and urban climate-proofing. Fifth, WSUD is implemented with delayed and regulated overflows to the sewer system. The results are partially adopted by the City of Copenhagen and currently under pilot testing.

    Benzene is a carcinogenic compound, which is emitted from petrol-fuelled cars and thus is found ubiquitous in all cities. As part of the project Monitoring of Atmospheric Concentrations of Benzene in European Towns and Homes (MACBETH) six campaigns were carried out in the Municipality of Copenhagen, Denmark. The campaigns were distributed over 1 year. In each campaign, the personal exposure to benzene of 50 volunteers (non-smokers living in non-smoking families) living and working in Copenhagen was measured. Simultaneously, benzene was measured in their homes and in an urban network distributed over the municipality. The Radiello diffusive sampler was applied to sample 5 days averages of benzene and other hydrocarbons. Comparison of the results with those from a BTX-monitor showed excellent agreement. The exposure and the concentrations in homes and in the urban area were found to be close to log-normal distribution. The annual averages of the geometrical mean values were 5.22, 4.30 and 2.90 μg m -3 for personal exposure, home concentrations and urban concentrations, respectively. Two main parameters are controlling the general level of benzene in Copenhagen: firstly, the emission from traffic and secondly, dispersion due to wind speed. The general level of exposure to benzene and home concentrations of benzene were strongly correlated with the outdoor level of benzene, which indicated that traffic is an important source for indoor concentrations of benzene and for the exposure to benzene.

  17. The psychologist as a poet: Kierkegaard and psychology in 19th-century Copenhagen.

    PubMed

    2016-11-01

    Psychology had an early start at the University of Copenhagen in the first half of the 19th century, where it was taught as the major part of a compulsory course required of all first-year students. Particularly important in the establishment of psychology at the university was Frederik Christian Sibbern, who was professor of philosophy from 1813 to 1870. Sibbern wrote numerous works on psychology throughout his career. In his first book on psychology, Sibbern expressed the view that the ideal psychologist should also be a poet. Søren Kierkegaard, Sibbern's student, was precisely such a poet-psychologist. Kierkegaard discussed psychology in many of his works, reflecting the gathering momentum of psychology in 19th-century Copenhagen, Denmark. The article brings out some aspects of Kierkegaard's poetic and literary-imaginative approach to psychology. In his opinion, psychology was primarily a playful subject and limited in the questions about human nature it could answer, especially when it came up against the "eternal" in man's nature. Kierkegaard had a positive view of psychology, which contrasts sharply with his negative views on the rise of statistics and the natural sciences. In the latter half of the 19th century, psychology turned positivistic at the University of Copenhagen. This left little room for Kierkegaard's kind of poetic psychology. (PsycINFO Database Record

    Hairdressers are occupationally and personally exposed to hair dye substances and adverse reactions from the skin are well known. Currently, little is known about personal exposure to hair dye ingredients and temporary black tattoos. To investigate hairdressers' professional and personal risk exposures and to compare the frequency of temporary tattoos among hairdressers and subjects from the general population. A questionnaire was sent to 1679 Copenhagen hairdressers and 1063 (63.3%) responded; 3471 subjects from the general population in Copenhagen were asked about temporary black tattoos. Of the female hairdressers, 38.3% had coloured hair within the previous week. Adverse skin reactions to own hair dye were reported in 29.5%. In the hairdresser population, no significant association was observed between self-reported adverse skin reactions to hair dye and having had a temporary black tattoo when adjusted for sex, age, and atopy. A total of 19.0% of hairdressers (43.5% of apprentices) and 6.3% of participants from the general population had ever had a temporary black tattoo performed at one point. There were no differences in frequency of eczema after temporary tattooing between hairdressers and subjects in the general population. Almost all hairdressers (99.2%) used gloves for hair colouring, 51% for high/low lighting, 39.6% for perming and 21.1% used gloves for shampooing. In conclusion, skin reactions to hair colour are frequent among Copenhagen hairdressers. Temporary black tattoos were more frequent among hairdressers than in a sample of the general population and increased with decreasing age.

    BACKGROUND—It is the general impression that the prevalence of asthma has increased during recent decades. A study was undertaken to investigate asthma prevalence, respiratory symptoms, and lung function in young adults in the City of Copenhagen 15 years apart.
METHODS—Men and women aged 20-35 years were sampled from the general population living in a defined area of central Copenhagen. The first examination took place in 1976-8 and comprised 1034 subjects (response rate 67.2%). A new sample comprising 1104 subjects (response rate 62.6%) from exactly the same area was examined 15 years later in 1991-4. All participants answered a questionnaire on respiratory symptoms and diseases and performed spirometric tests with measurement of forced expiratory volume in one second (FEV1) and forced vital capacity (FVC).
RESULTS—The prevalence of self-reported asthma increased from 1.5% in the first survey to 4.8% in the second survey (p<0.001). Asthmatic subjects had, on average, poorer lung function than non-asthmatic subjects in terms of FEV1 and this difference was more pronounced in the second survey than in the first (10.0% of predicted versus 2.4% of predicted). Smoking decreased significantly from 62% in 1976-8 to 45% in 1991-4 (p<0.001).
CONCLUSIONS—The prevalence of self-reported asthma has increased significantly among young adults in Copenhagen over a 15 year period. The severity of asthma, as judged by the level of FEV1, has also increased. These findings cannot be explained by changes in smoking habits.

    Using reports from 154 examinations of alleged torture victims among asylum applicants to Denmark conducted by the Department of Forensic Medicine, University of Copenhagen, between 2001 and 2013, we have categorized the victims into four geographical regions, as well as according to the conflict that caused them to flee. The torture incidents described by the victims were divided into 12 different categories defined by the Istanbul Protocol. These data were cross referenced in order to identify any differences in the prevalence of the 12 forms of torture. The study showed that crush injuries were only reported by refugees from Asia, including Afghanistan and Pakistan, and that incidents of electrical torture were reported twice as frequently by torture victims from Middle Eastern and North African countries, though it was lower among Iraqis, Iranians and ethnic Kurds. Sexual torture was reported by 78% of females and 25% of males.

  3. Effects of inherited cores and magmatic overgrowths on zircon (U-Th)/He ages and age-eU trends from Greater Himalayan sequence rocks, Mount Everest region, Tibet

    Previous constraints on the timing and rate of exhumation of the footwall of the South Tibetan detachment system (STDS) north of Mount Everest suggest rapid Miocene cooling from ˜ 700°C to 120°C between ˜14-17 Ma. However, 25 new single grain zircon He ages from leucogranites intruding Greater Himalayan Sequence rocks in the footwall of the STDS are between 9.9 and 15 Ma, with weighted mean ages between 10 and 12 Ma. Zircon grains exhibit a positive correlation between age and effective uranium (eU). Laser ablation zircon U-Pb geochronology, detailed SEM observations, and laser ablation depth-profiling of these zircons reveal low-eU 0.5-2.5 Ga inherited cores overgrown by high-eU 17-22 Ma rims. This intragranular zonation produces ages as much as 32% too young when a standard alpha-ejection correction assuming uniform eU distribution is applied. Modeling of the effects of varying rim thickness and rim eU concentration on the bulk grain eU and alpha-ejection correction suggests that zonation also exerts the primary control on the form of the age-eU correlation observed. Application of grain-specific zonation-dependent age corrections to our data yields zircon He ages between 14 and 17 Ma, in agreement with AFT and 40Ar/39Ar ages. Growth of magmatic rims followed by cooling to < 120°C within 1-6 million years supports rapid tectonic exhumation associated with slip along the STDS in the Miocene. This study highlights the importance of characterizing parent nuclide zonation in zircon He studies which seek to understand the timing of exhumation along exhumed crustal blocks.

    To examine the treatment practices for cancer pain relief and adverse event management, and the factors related to patient outcomes in the participating countries/regions. The study was a cross-sectional survey conducted between September and December 2013 in 10 countries/regions across Asia. Adult patients with a history of cancer pain at least 1 month before study entry completed the survey questionnaire. A total of 1190 patients were included. The mean Box Scale-11 (BS-11) pain score was 6.0 (SD 2.1), with 86.2% experiencing moderate-to-severe pain and 53.2% receiving opioids at time of the survey. The mean BS-11 scores were 5.3 (SD 2.1) in the "others" (single non-opioid medication or untreated) group, 6.3 (SD 2.0) in the ≥2 non-opioids group and 6.7 (SD 1.9) in the opioid group. The proportions of patients experiencing moderate-to-severe pain were 79.1%, 87.3% and 93.7%, respectively. About 70% of patients reported adverse events due to their pain medications, about half had received medications to manage these symptoms. Adverse events were negatively associated with activities of daily living (P < 0.0001). Pain and hindrance to activities of daily living were negatively associated with employment status (P = 0.003 and 0.021). Unemployment was significantly associated with poorer quality of life (P < 0.0001). This analysis demonstrates inadequate management of cancer pain and treatment-related adverse events in the participating cohort. Pain and inadequate management of adverse events were negatively associated with patients' overall well-being. More collaborative efforts should be taken to optimize pain treatment and increase awareness of adverse event management in physicians. © 2017 John Wiley & Sons Australia, Ltd.

  5. Paleotectonic and paleogeographic evolution of greater China

    In this study, we utilize plate tectonic history of Central Asia to constrain understanding of sedimentary basin development and to show how regional scale tectonic events affect play elements for major basins of greater China. Tectonic framework and paleogeography are used as a constraint on models for basin formation, climate distribution and accommodation which in turn control distribution of reservoir, source, seal and trap. Greater China is an artifact of Phanerozoic tectonics. It has a protracted history of continental deformation as amalgamation of crustal blocks and island arc/subduction and accretion complexes occurred. Early Paleozoic hydrocarbon systems are dominated by extensive carbonate platform and Permian and younger systems are dominated by continental and lacustrine sedimentation. The basement of greater China consists of continental and accretion crust. The crustal blocks include South and North China, Indochina, Tibet and Tarim, and accretion blocks include the Altaids and Manchurides. The relative positions and interactions of these blocks during Paleozic and Mesozoic time resulted in formation of greater China. Final amalgamation and deformation occurred in Eocene time when India collided with Asia. The discussions consist of presentation of a model for tectonic evolution of these blocks and their paleogeography through Phanerozoic time. This is done with maps at 1:8 million scale covering nine time slices, three in the Paleozoic, three in the Mesozoic and three in the Cenozoic.

    I conducted new vorticity and deformation temperatures studies to test competing models of the exhumation of the mid-crustal rocks exposed in the Dolpo region (West Nepal). My results indicate that the Main Central Thrust is located ∼5 km structurally below the previous mapped locations. Deformation temperature increasing up structural section from ∼450 °C to ∼650 °C and overlap with peak metamorphic temperature indicating that penetrative shearing was responsible for the exhumation of the GHS occurred at "close" to peak metamorphic conditions. I interpreted the telescoping and the inversion of the paleo-isotherms at the base of the GHS as produced mainly by a sub-simple shearing (Wm = 0.88-1) pervasively distributed through the lower portion of the GHS. My results are consistent with hybrid channel flow-type models where the boundary between lower and upper portions of the GHS, broadly corresponding to the tectonometamorphic discontinuity recently documented in west Nepal, represents the limit between buried material, affected by dominant simple shearing, and exhumed material affected by a general flow dominates by pure shearing. This interpretation is consistent with the recent models suggesting the simultaneous operation of channel flow- and critical wedge-type processes at different structural depth.

    When George Gamow was offered a position at George Washington University in 1934, one of the conditions he set for acceptance was the establishment of an annual physics conference at that university, co-sponsored by the Carnegie Institution. Foggy Bottom, the Washington neighborhood where GWU is located, was not particularly known for physics. Gamow, however, wished to bring the ``spirit of Copenhagen'' to that locale and attract an international group of theorists. The Washington Conference on Theoretical Physics first convened in 1935 and assembled annually until 1947, except for a three year break during the war. Ironically, just like the Institute for Theoretical Physics in Copenhagen itself, the conference was galvanized the most by Bohr's actual presence. In its fifth, and best known meeting, held in 1939, Bohr stunned the audience when he announced the successful completion of nuclear fission. After the tenth meeting in 1947, Gamow's focus had been turning from nuclear physics to cosmology, he had begun to work more closely with graduate students and local collaborators and, in light of diminished interest, the conference was no longer held. In this talk I will delineate the successes and limitations of the Washington Conference on Theoretical Physics. )

    This study investigates the potential health risk from urban gardening. The concentrations of the trace elements arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) in five common garden crops from three garden sites in Copenhagen were measured. Concentrations (mg/kg dw) of As were 0.002-0.21, Cd 0.03-0.25, Cr < 0.09-0.38, Cu 1.8-8.7, Ni < 0.23-0.62, Pb 0.05-1.56, and Zn 10-86. Generally, elemental concentrations in the crops do not reflect soil concentrations, nor exceed legal standards for Cd and Pb in food. Hazard quotients (HQs) were calculated from soil ingestion, vegetable consumption, measured trace element concentrations and tolerable intake levels. The HQs for As, Cd, Cr, Cu, Ni, and Zn do not indicate a health risk through urban gardening in Copenhagen. Exposure to Pb contaminated sites may lead to unacceptable risk not caused by vegetable consumption but by unintentional soil ingestion.

    Objective To quantify the effects of increased cycling on both mortality and morbidity. Design Health Impact Assessment. Setting Cycling to place of work or education in Copenhagen, Denmark. Population Effects were calculated based on the working-age population of Copenhagen. Main outcome measures The primary outcome measure was change in burden of disease (measured as disability-adjusted life years (DALY)) due to changed exposure to the health determinants physical inactivity, air pollution (particulate matter <2.5 μm) and traffic accidents. Results Obtainment of the proposed increase in cycling could reduce the burden of disease in the study population by 19.5 DALY annually. This overall effect comprised a reduction in the burden of disease from health outcomes associated with physical inactivity (76.0 DALY) and an increase in the burden of disease from outcomes associated with air pollution and traffic accidents (5.4 and 51.2 DALY, respectively). Conclusion This study illustrates how quantitative Health Impact Assessment can help clarify potential effects of policies: increased cycling involves opposing effects from different outcomes but with the overall health effect being positive. This result illustrates the importance of designing policies that promote the health benefits and minimise the health risks related to cycling. PMID:22833650

    To investigate socioeconomic patterning of physical activity resources in Copenhagen. We used multivariate logistic regression analysis to examine the association between physical activity-supportive resources [public open space (POS), cycling and walking paths, sports facilities, and intersection density] and neighborhood sociodemographic indicators (low education, recent immigrants, children under 15 yr, and household income). Neighborhoods with high proportions of residents with low education were most likely to have POS (OR = 2.63; CI: 2.10-3.29), paths (OR = 3.60; CI: 2.84-4.56) and sports facilities (OR = 5.96; CI: 4.31-8.24). Mid-to-low income areas were less likely to contain POS (OR = 67; CI: 0.49-0.90), paths (OR = 0.36; CI: 0.26-0.50), and sports facilities (OR = 0.48; CI: 0.30-0.77). Areas with children were less likely to have connected streets (OR = 0.51; CI: 0.31-0.83) but more likely to have POS (OR = 1.40; CI: 1.15-1.70) and paths (OR = 1.52; CI: 1.25-1.85). Residents living in areas with high proportions of low education or young children are likely to have high exposure to physical activity resources. Exposure to physical activity resources in Copenhagen may not explain the inequalities in physical activity behavior. Further examination of exposure to built environment resources is warranted.

    Autoerotic fatalities in the Greater Dusseldorf area correspond to the relevant medicolegal literature. Our results included exclusively young to middle-aged, usually single men who were found dead in their city apartments. Clothing and devices used showed a great variety. Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

    The mechanisms involved in the initiation and development of the Greater Everglades peatland ecosystems in South Florida (USA) remain a topic of discussion. In this study, we present an overview of basal ages of peat deposits in South Florida, which shows two major episodes of peatland initiation between 7.0-4.5 kyr and 3.5-2.0 kyr. Our analysis of regional climate proxy datasets led to three alternative hypotheses that may explain the timing and duration of these two peatland initiation episodes: (1) decreased drainage due to relative sea level (RSL) rise during the Holocene (2) gradual increase in precipitation throughout the Holocene, and (3) a combination of increasing precipitation, rising RSL and oscillations in the climate system. We test whether these three hypotheses can explain the pattern of initiation and development of the Greater Everglades peatlands using models that simulate the non-linear processes involved in peat production and decomposition in combination with the local drainage conditions of Southern Florida. The model results suggest that RSL-rise alone cannot predict the onset of peat initiation in the Greater Everglades using our model setup. The model also implies that the climate was wet enough for peat development also during the early Holocene. The first two hypothesized mechanisms in combination with climate oscillations may explain the onset of peat accumulation at 8.2 kyr BP. The two-phased character of peat land initiation may be explained by the spatial distribution of local drainage conditions. As peatland development is highly non-linear, our model uncovers a mechanistic way how peats can suddenly shift from a dry high equilibrium to a wet low equilibrium resulting in lake formation as observed in paleo-ecological studies in the Greater Everglades.

    To investigate separate and combined associations of occupational social class and personality traits with late midlife leisure-time physical activity duration and intensity. Cross-sectional data from the Copenhagen Aging and Midlife Biobank ( N = 4,649) were analyzed using linear regression models with leisure-time physical activity (metric equivalence) as outcome. Low versus high occupational social class was associated with 4% (95% confidence interval [CI] = [3%, 5%]) greater leisure-time physical activity duration, but 2% (CI = [1%, 3%]) lower intensity. Each 10-unit increase in extraversion was associated with 5% (CI = [2%, 8%]) greater duration. Intensity increased by each 10-unit increase in conscientiousness (6%, CI = [4%, 7%]), openness (3%, CI = [1%, 4%]), neuroticism (3%, CI = [1%, 4%]), and extraversion (5%, CI = [4%, 7%]). Conscientiousness was positively associated with duration in low, but not in high, occupational social class (interaction p value = .002). Higher occupational social class was associated with lower leisure-time physical activity duration, but higher intensity. Extraversion was positively associated with duration and intensity. Conscientiousness, openness, and neuroticism were positively associated with intensity. Overall, interactions were not consistent.

    Temperature, a key climate change indicator, is expected to increase substantially in the Northern Hemisphere, with potentially grave implications for human health. This study is the first to investigate the association between the daily 3-hour maximum apparent temperature (Tapp(max)), and respiratory, cardiovascular and cerebrovascular mortality in Copenhagen (1999-2006) using a case-crossover design. Susceptibility was investigated for age, sex, socio-economic status and place of death. For an inter-quartile range (7 °C) increase in Tapp(max), an inverse association was found with cardiovascular mortality (-7% 95% CI -13%; -1%) and none with respiratory and cerebrovascular mortality. In the cold period all associations were inverse, although insignificant.

    In the late 1920s and early 1930s, Copenhagen, the center of the development of quantum physics, was also the home of abundant humor. As a respite from the intensive and highly competitive efforts taking place to characterize fundamental interactions on an atomic scale, physicists took the time to develop satirical letters, articles, plays and other works. Written in German, English and other languages, many of these efforts were quite pointed and clever. This paper will focus on several examples of these humorous contributions, including letters exchanged between Oskar Klein and Paul Ehrenfest in 1930, articles written for the ``Journal of Jocular Physics,'' and a well-known parody of Faust. We'll show how these pieces reflect the political and scientific climate of the era, and attempt to characterize the personal styles of the some of the researchers involved.

The two-phased character of peatland initiation maybe explained by the spatial distribution of local drainage conditions. As peatland development is highly nonlinear, our model uncovers a mechanistic way how peats can suddenly shift from a dry high equilibrium to a wet low equilibrium resulting in lake formation as observed in paleoecological studies in the Greater Everglades.

    Alfred Lehmann (1858-1921) was the pioneer of experimental psychology in Denmark. He established a laboratory of psychophysics in Copenhagen in 1886 after spending a winter in Wundt's laboratory. Philosophical psychology had been taught for the better part of the nineteenth century at the University of Copenhagen and had enjoyed a positivistic turn with the philosophers Harald Høffding (1843-1931) and Kristian Kroman (1846-1925). Shortly after establishing his laboratory, Lehmann criticized Høffding's theory of "unmediated recognition," which led to a sharp dispute between them on the nature of recognition. It has been claimed that this was a direct cause of Lehmann's slow advance at the University of Copenhagen. Archival sources show that Høffding, though having a very different conception of psychology from Lehmann, was on most occasions supportive of Lehmann and thus played an important role in establishing experimental psychology at the University of Copenhagen.

  4. The emergence of Quantum Schools: Munich, Göttingen and Copenhagen as new centers of atomic theory

    2001-01-01

    The institutes of Arnold Sommerfeld in Munich, Niels Bohr in Copenhagen, and Max Born in Göttingen became the leading centers for the study of quantum theory in the first decades of the twentieth century. Although founded for a broader range of theoretical physics, the quantum became the major topic of research in Munich after the Bohr-Sommerfeld-model of the atom (1913-16). The heyday came in the 1920s, when Bohr's and Born's institutes started operation and became further attractive centers for ambitious theorists all over the world. The discovery of quantum mechanics (1925) should be regarded not only as the achievement of a few young geniuses (in particular Werner Heisenberg and Wolfgang Pauli) but also as the result of a collaborative effort emerging in the new social and intellectual environment of their teachers' schools in Munich, Göttingen and Copenhagen.

    To investigate whether exposure to fast-food outlets and supermarkets is socio-economically patterned in the city of Copenhagen. The study was based on a cross-sectional multivariate approach to examine the association between the number of fast-food outlets and supermarkets and neighbourhood-level socio-economic indicators. Food business addresses were obtained from commercial and public business locators and geocoded using a geographic information system for all neighbourhoods in the city of Copenhagen (n 400). The regression of counts of fast-food outlets and supermarkets v. indicators of socio-economic status (percentage of recent immigrants, percentage without a high-school diploma, percentage of the population under 35 years of age and average household income in Euros) was performed using negative binomial analysis. Copenhagen, Denmark. The unit of analysis was neighbourhood (n 400). In the fully adjusted models, income was not a significant predictor for supermarket exposure. However, neighbourhoods with low and mid-low income were associated with significantly fewer fast-food outlets. Using backwise deletion from the fully adjusted models, low income remained significantly associated with fast-food outlet exposure (rate ratio = 0·66-0·80) in the final model. In the city of Copenhagen, there was no evidence of spatial patterning of supermarkets by income. However, we detected a trend in the exposure to fast-food outlets, such that neighbourhoods in the lowest income quartile had fewer fast-food outlets than higher-income neighbourhoods. These findings have similarities with studies conducted in the UK, but not in the USA. The results suggest there may be socio-economic factors other than income associated with food exposure in Europe.

  6. Risk factors for hepatitis B virus infection in heterosexuals attending a venereal disease clinic in Copenhagen.

    Markers of hepatitis B virus (HBV) infection were measured in 465 non-drug-abusing heterosexually transmitted disease (STD) patients. HBV markers were found in altogether 70 persons, of whom 7 were HBsAg carriers. Those chronically infected were all born in HBV intermediate/high endemic areas. Gonorrhoea was the only STD that was correlated to an increased risk of HBV markers. Number of sexual partners, sex and age was not correlated with HBV infection, irrespective of country of origin. The risk of having HBV markers in an STD clientele in Copenhagen was highly dependent on the country of birth, as the prevalences were 7% (21/307) in persons born in Denmark, 19% (9/47) in those born in other low endemic areas and 36% (40/111) in those born in intermediate/high endemic areas. Falling incidence of gonorrhoea and other STD may render it difficult to point out risk factors indicative of HBV immunization in heterosexual STD patients. In low-risk countries, screening for HBV markers should however be offered to all immigrants and refugees as a part of an HBV immunization program.

    Older people from ethnic minorities are underrepresented in dementia care. Some of the determinants of access to care are knowledge and perceptions of dementia, which may vary between ethnic groups in the population. The aims of this study were to compare knowledge and perceptions of dementia and Alzheimer's disease (AD) among four ethnic groups in Copenhagen, Denmark, and to assess the influence of education and acculturation. Quantitative survey data from 260 participants were analyzed: 100 native Danish, and 47 Polish, 51 Turkish, and 62 Pakistani immigrants. Knowledge and perceptions of dementia and AD were assessed with the Dementia Knowledge Questionnaire (DKQ) supplemented with two questions from the Alzheimer's Disease Awareness Test (ADAT). Knowledge and perceptions of dementia and AD in the four groups were compared, and the influence of education and acculturation was assessed. Group differences were found on the DKQ total score as well as all sub-domains. Turkish and Pakistani people were most likely to hold normalizing and stigmatizing views of AD. Level of education and acculturation had limited influence on dementia knowledge, accounting for 22% of the variance at most and had only minor influence on perceptions of AD. Lacking knowledge and certain perceptions of dementia and AD may hamper access to services in some ethnic minority groups. Ongoing efforts to raise awareness that dementia and AD are not part of normal aging, particularly among Turkish and Pakistani communities, should be a high priority for educational outreach.

  8. The physiological challenges of the 1952 Copenhagen poliomyelitis epidemic and a renaissance in clinical respiratory physiology

    PubMed Central

    2005-01-01

    The 1952 Copenhagen poliomyelitis epidemic provided extraordinary challenges in applied physiology. Over 300 patients developed respiratory paralysis within a few weeks, and the ventilator facilities at the infectious disease hospital were completely overwhelmed. The heroic solution was to call upon 200 medical students to provide round-the-clock manual ventilation using a rubber bag attached to a tracheostomy tube. Some patients were ventilated in this way for several weeks. A second challenge was to understand the gas exchange and acid-base status of these patients. At the onset of the epidemic, the only measurement routinely available in the hospital was the carbon dioxide concentration in the blood, and the high values were initially misinterpreted as a mysterious “alkalosis.” However, pH measurements were quickly instituted, the PCO2 was shown to be high, and modern clinical respiratory acid-base physiology was born. Taking a broader view, the problems highlighted by the epidemic underscored the gap between recent advances made by physiologists and their application to the clinical environment. However, the 1950s ushered in a renaissance in clinical respiratory physiology. In 1950 the coverage of respiratory physiology in textbooks was often woefully inadequate, but the decade saw major advances in topics such as mechanics and gas exchange. An important development was the translation of the new knowledge from departments of physiology to the clinical setting. In many respects, this period was therefore the beginning of modern clinical respiratory physiology. PMID:16020437

    The death rate for fatal fire accidents in Denmark has doubled since 1951, mostly due to an increase in the number of fire accidents associated with smoking. The most common cause of residential fire deaths in Denmark today is smoking, often combined with alcohol intoxication or handicap. This was a case-control study of fatal fire accidents in private homes in the municipality of Copenhagen from 1991 to 1996. The fatal fire accidents were identified from a police register, and the two non-fatal fire accidents registered immediately before and after each fatal fire were selected as a control group. Information about the circumstances surrounding the fires was derived from the police reports. Multivariate logistic regression analysis was used to estimate the risk associated with each variable after adjusting for confounders. The analysis was performed on the basis of the theoretical model in which the variables were part of a causal network. The following five variables seemed to be of most importance: (1) localization of the victim close to the source of ignition (OR = 11), (2) physical handicaps (OR = 5), (3) chronic alcoholism (OR = 7), (4) clothing fires (OR = 24), and (5) alarm being given by a person not present at the scene of fire (OR = 33). Preventive measures are discussed in the light of the results.

    We present a re-analysis of the Geneva-Copenhagen survey, benefiting from the infrared flux method to improve upon the accuracy of the derived stellar effective temperatures and using the latter to build a consistent and improved metallicity scale. Metallicities are calibrated on high-resolution spectroscopy and checked against four open clusters and a moving group, showing excellent consistency. The new temperature and metallicity scales provide a better match to theoretical isochrones, which are used for a Bayesian analysis of stellar ages. With respect to previous analyses, our stars are on average 100K hotter and 0.1dex more metal rich, shifting the peak of the metallicity distribution function around the solar value. From Stromgren photometry we are able to derive for the first time a proxy for [Fe] abundances, which enables for a tentative dissection of the chemical thin and thick disc. We find evidence for the latter being composed of an old, mildly but systematically alpha-enhanced population extending to super solar metallicities, in agreement with spectroscopic studies. Our revision offers the largest existing kinematically unbiased sample of the solar neighbourhood that contains full information on kinematics, metallicities and ages and thus provides better constraints on the physical processes relevant in the build-up of the Milky Way disc, enabling a better understanding of the Sun in a Galactic context.

    This study is a mapping of intestinal protozoal and pathogenic bacterial infections, and sexually transmitted urethral and anorectal infections among 365 consecutive male patients attending a veneric disease (VD) clinic in Copenhagen. The profile of diseases was strongly correlated to sexual life-style. Amoebiasis and giardiasis were found respectively in 31.9% and 13.8% of homosexuals. None of the heterosexuals had pathogenic protozoa. Protozoal infections were correlated to anilingus. Forty-five percent of the patients were infected in Denmark. Travelling to endemic areas was of no obvious importance. Among males with homosexual partners, 14% had rectal infections. Gonococcal and chlamydial infections were equally frequent. Three percent had symptomatic anorectal herpes simplex infection and 11% anal warts. Gastrointestinal symptoms were not reliable indicators of gastrointestinal infection; symptoms were claimed frequently among homosexuals without infections compared to heterosexuals. Urethral gonorrhoea and/or chlamydia infections were diagnosed in 39% of the heterosexuals compared to only 10% of the homo-bisexuals. Twelve percent of the homosexuals had untreated early syphilis, whereas syphilis was exceptional among heterosexuals. The total burden of infections expressed as the actual number of infections was largest among homosexuals, 40.4%, 22.4%, and 5.3% having one, two, and three infections respectively.

  12. Sense of coherence and physical health. A "Copenhagen interpretation" of Antonovsky's SOC concept.

    According to Antonovsky's (Aaron Antonovsky, 1923-1994) sense of coherence (SOC) model, persons with a high SOC have the ability to benefit from their general defense mechanisms in order to overcome stressful situations. In a health-disease continuum, this leads to the development towards health. However, Antonovsky's global hypothesis that the strength of the SOC may influence the physical health status of a person could not be proven. Flensborg-Madsen et al. from Copenhagen were able to provide a new access regarding SOC and health. They investigated the mixture of emotional aspects and mental constructions as a possible cause for fairly low correlation between SOC and physical health. Thus, in an empirical way, they described "emotional coherence" in relation to physical health, while "mental coherence" was linked to psychological health. These authors introduced the idea of applying a shortened version of the original 29-item SOC questionnaire, but have not yet developed or tested the shortened questionnaire. Backed by their important findings, it appears to be promising to consider the use of the SOC questionnaire as standardized by Antonovsky, but cleared of the items regarding "predictability", i.e., Flensborg-Madsen et al. suggested that the items on "predictability" be excluded from the SOC scale when a correlation to physical health is to be investigated. Further investigations in this area of research will be of high impact, not only for health sciences, but also for medical practice.

    Two stormwater infiltration trenches were installed in 1993 in an area in central Copenhagen. The system was monitored continuously for almost three years after establishment, and a small reduction in performance over that time, possibly due to clogging, was noted. A new study was conducted in 2009 to see whether the reduction in performance has continued and to determine how the system performs today. Water levels in the trenches were monitored for almost 4 months, and from this period seven events were selected to analyse the infiltration rate. A comparison with similar analyses on storm sequences from the first 3 years of operation shows that the infiltration has decreased since the establishment of the system 15 years ago. The decrease is statistically significant (p<0.01). A clogging model was fitted to the data and predictions were made for future performance. The results show that the system will discharge around 10 times more annual overflow to the sewers after 100 years of operation compared to the initial volumes, if clogging continues at current rates. This corresponds to 60% of the total runoff from the area. The results show that clogging and proper maintenance are important factors to consider when implementing stormwater infiltration trenches.

    Increasing stress on water resources is driving urban water utilities to establish new concepts for water supply. This paper presents the consequences of proposed alternative water supply options using a unique combination of quantitative and qualitative methods from different research fields. A former industrial harbor area in Copenhagen, Denmark, is currently under development and all infrastructure will be updated to accommodate 40,000 inhabitants and 40,000 jobs in the future. To reduce stress on water resources it has been proposed to establish a secondary water supply in the area as an alternative to the conventional groundwater-based drinking water supply. Four alternative concepts for a secondary water supply have been considered: 1) slightly polluted groundwater for use in toilets and laundry, 2) desalinated brackish water for use in toilets, laundry, and dishwashers, 3) desalinated brackish water for all uses, including drinking water, and 4) local reclamation of rain and gray water for use in toilets and laundry. The concepts have been evaluated for their technical feasibility, economy, health risks, and public acceptance, while the concepts' environmental sustainability has been assessed using lifecycle assessment and freshwater use impact methods. The holistic assessment method exposes conflicting preference solutions depending on assessment criteria, and reveals multi-faceted consequences for choices in urban water management. Not one concept turns out unambiguously positive based on the evaluation criteria included here, but the systematic evaluation will leave decision-makers informed on the consequences of their choices.

  15. Time separation as a hidden variable to the Copenhagen school of quantum mechanics

    The Bohr radius is a space-like separation between the proton and electron in the hydrogen atom. According to the Copenhagen school of quantum mechanics, the proton is sitting in the absolute Lorentz frame. If this hydrogen atom is observed from a different Lorentz frame, there is a time-like separation linearly mixed with the Bohr radius. Indeed, the time-separation is one of the essential variables in high-energy hadronic physics where the hadron is a bound state of the quarks, while thoroughly hidden in the present form of quantum mechanics. It will be concluded that this variable is hidden in Feynman's rest of the universe. It is noted first that Feynman's Lorentz-invariant differential equation for the bound-state quarks has a set of solutions which describe all essential features of hadronic physics. These solutions explicitly depend on the time separation between the quarks. This set also forms the mathematical basis for two-mode squeezed states in quantum optics, where both photons are observable, but one of them can be treated a variable hidden in the rest of the universe. The physics of this two-mode state can then be translated into the time-separation variable in the quark model. As in the case of the un-observed photon, the hidden time-separation variable manifests itself as an increase in entropy and uncertainty.

    The Greater Vancouver Regional District commissioned an 18-month planning and predesign study to define the components in a comprehensive water and predesign study to define the components in a comprehensive water quality improvement plan for its 2,500-ML/d (660-mgd) system. The study included three primary tasks: (1) predesign of disinfection and corrosion control facilities, (2) a 12-month pilot testing program using parallel pilot plants at the Seymour and Capilano water supply reservoirs, and (3) planning for future filtration plants. The results of the study identified chlorine, ammonia, sulfur dioxide, soda ash, and carbon dioxide in a two-stage treatment approach as the recommended disinfection and corrosion control scheme for the low-pH, low-alkalinity water supplies. The pilot-plant studies confirmed that direct filtration using deep-bed monomedium filters operating at a loading rate of 22.5 m/h provided excellent treatment performance and productivity over a wide range of raw-water quality. Ozonation was studied extensively and found not to be beneficial in the overall treatment performance. The phased improvement plan for the disinfection, corrosion control, and filtration facilities has an estimated capital cost of about Can$459 million.

    The Health Administration Agencies of many municipalities in Greater Buenos Aires (GBA) receive frequent reports on triatomines in houses. The aim of this work was to identify and describe the dispersal foci of Triatoma infestans in an urban neighborhood of GBA, and contribute to the knowledge of the epidemiological situation in the region. In June 1998, potentially infested places were entomologically evaluated. T. infestans was only detected in a hen building for egg production, which housed approximately 6,000 birds. A total of 2,930 insects were collected. Density was about 9 triatomines/m(2). The proportions of fifth instar nymphs and adults were significantly higher than those of the other stages (p<0.001). The number of triatomines collected largely exceeded the highest domestic infestation found in one house from rural endemic areas of Argentina. Though triatomines were negative for Trypanosoma cruzi, they could acquire the parasite by coming in contact with infected people living in GBA. Besides, the numerous and widely distributed places housing hens and chickens, would favor the settlement of the vector. Together, both facts may constitute a risk of parasitic vectorial transmission. It is recommended to intensify systematic activities of vector search and case detection in GBA.

    Lymphoedema is increasingly recognized as a significant problem in healthcare. The number of patients is growing, posing a future challenge to healthcare systems and economics. Over the past decade, specialized lymphoedema management has been established around the world to accommodate the growing demands. However, information on organization, experiences and outcome are scarce. To conduct a clinical perspective analysis describing the establishment, organization, function and results of a new, multidisciplinary lymphoedema centre functioning as a university hospital unit in connection to a department of dermatology and the Copenhagen Wound Healing Center and integrated as a national expert function in the public healthcare organization of Denmark. Data were collected following the establishment of a lymphoedema centre based on the structured, multidisciplinary organization of lymphoedema management. During the first 4·5 years a total of 8058 patient consultations were performed. The mean duration of symptoms at the first visit was 19 years (range 1-67) and 31% of patients had never received any diagnosis or treatment prior to referral. Complications were found in 48% of referred patients. All patients received appropriate diagnostic investigations and treatment according to best practice. Multidisciplinary assessment involving four or more different healthcare professions was needed in 86% of cases. Research opportunities and expert education of staff were enhanced. A multidisciplinary lymphoedema centre improves management, knowledge and awareness of lymphoedema. This model, with minor adjustments, may be applicable for other regions and countries. © 2012 The Authors. BJD © 2012 British Association of Dermatologists.

    The Copenhagen Psychosocial Questionniare (COPSOQ) has many advantages as compared to other similar instruments, i.a., it is not related to one single theoretical model and it measures a wide spectrum of psychosocial working conditions that have shown proven impact on health. The aim of the article is to summarize information on psychometric properties of 11 scales in the Polish version: Quantitative Demands, Emotional Demands, Influence at Work, Social Support, Possibilities for Development, Meaning of Work, Role Clarity, Quality of Leadership, Job Insecurity, Job Satisfaction, and General Health. Analyses were based on the results of 4 research projects, in which the Polish version of the COPCOQ scales has been used: on a representative sample of Polish nurses (N = 4354), job insecurity in 2 groups of civil servants (N = 295, N = 724), mobbing among teachers (N = 1037) and psychological consequences of restructuring (N = 1396). The following psychometric characteristics were analysed: internal reliability, theoretical validity, and factorial validity. Internal reliability of the following 8 scales was found satisfactory: Quantitative Demands, Influence at Work, Social Support, Possibilities for Development, Meaning of Work, Quality of Leadership, Job Satisfaction, and General Health (Cronbach's α = 0.7-0.91, depending on the scale). The results of exploratory factor analyses indicated factorial separateness of the above mentioned scales. Theoretical validity of 11 scales was confirmed; they were associated with variables that can be regarded as their validity criteria. The 8 COPSOQ scales, in the Polish version, can be recommended for using in the research involving psychosocial job characteristics. Mean scores on these scales and standard deviations given in the article can serve as reference points during an evaluation of received results. Med Pr 2017;68(3):329-348.

    The prospect of exquisite-precision parallaxes that will be enabled by the Gaia satellite dramatically changes the landscape of observational stellar astrophysics: If one considers the Hipparcos double stars that lie within 250 pc of the Solar system, a parallax determined by Gaia would yield an uncertainty under 1% for all these objects. In this volume, there are 591 Hipparcos double star discoveries and 160 spectroscopic binaries from the Geneva-Copenhagen spectroscopic survey in the declination range of -20° to -90°. These two samples are important as a source of new binaries from which we will derive masses, component luminosities, and effective temperatures in the coming years. The northern hemisphere counterpart of these objects have been systematically observed at the WIYN Telescope by Horch and collaborators (Horch, E. P., van Altena, W. F., Howell, S. B., Sherry, W. H., & Ciardi, D. R. 2011, AJ, 141, 180). On the other hand, Tokovinin has shown the ability of HRCam at the CTIO/SOAR 4m telescope for binary star research. In 2014 we started a speckle survey with SOAR+HRCam that will complement and significantly extend those previous efforts, allowing us to compile a unique all-sky, volume-limited speckle survey of these two primary samples. So far 12 nights (spread over 3 semesters) have been granted through the Chilean reserved time, with lots of binaries confirmed, many new binaries found, and with several multiple systems discovered (Tokovinin et al., 2015, AJ, 150, 50 and 2016, AJ, 151, 153). Our survey, when complete, will open the door to many sensitive tests of stellar evolution theory, and a large number of new points on the MLR. With this we will truly be able to investigate effects such as metallicity and age on the MLR for the first time. In cases where one component has evolved off the main sequence, age determinations will also be possible.

    At last, all the major emitters of greenhouse gases (GHGs) have agreed under the Copenhagen Accord that global average temperature increase should be kept below 2 °C. This study develops the criteria for limiting the warming below 2 °C, identifies the constraints imposed on policy makers, and explores available mitigation avenues. One important criterion is that the radiant energy added by human activities should not exceed 2.5 (range: 1.7–4) watts per square meter (Wm−2) of the Earth's surface. The blanket of man-made GHGs has already added 3 (range: 2.6–3.5) Wm−2. Even if GHG emissions peak in 2015, the radiant energy barrier will be exceeded by 100%, requiring simultaneous pursuit of three avenues: (i) reduce the rate of thickening of the blanket by stabilizing CO2 concentration below 441 ppm during this century (a massive decarbonization of the energy sector is necessary to accomplish this Herculean task), (ii) ensure that air pollution laws that reduce the masking effect of cooling aerosols be made radiant energy-neutral by reductions in black carbon and ozone, and (iii) thin the blanket by reducing emissions of short-lived GHGs. Methane and hydrofluorocarbons emerge as the prime targets. These actions, even if we are restricted to available technologies for avenues ii and iii, can reduce the probability of exceeding the 2 °C barrier before 2050 to less than 10%, and before 2100 to less than 50%. With such actions, the four decades we have until 2050 should be exploited to develop and scale-up revolutionary technologies to restrict the warming to less than 1.5 °C. PMID:20439712

    In May/June 2005 an outbreak of diarrhoeal illness occurred among company employees in Copenhagen. Cases were reported from seven of eight companies that received food from the same catering kitchen. Stool specimens from three patients from two companies were positive for Campylobacter jejuni. We performed a retrospective cohort study among employees exposed to canteen food in the three largest companies to identify the source of the outbreak and to prevent further spread. Using self-administered questionnaires we collected information on disease, days of canteen food eaten and food items consumed. The catering kitchen was inspected and food samples were taken. Questionnaires were returned by 295/348 (85%) employees. Of 247 employees who ate canteen food, 79 were cases, and the attack rate (AR) was 32%. Consuming canteen food on 25 May was associated with illness (AR 75/204, RR=3.2, 95%CI 1.3-8.2). Consumption of chicken salad on this day, but not other types of food, was associated with illness (AR=43/97, RR=2.3, 95%CI 1.3-4.1). Interviews with kitchen staff indicated the likelihood of cross-contamination from raw chicken to the chicken salad during storage. This is the first recognised major Campylobacter outbreak associated with contaminated chicken documented in Denmark. It is plausible that food handling practices contributed to transmission, and awareness of safe food handling and storage has since been raised among kitchen staff. The low number of positive specimens accrued in this outbreak suggests a general underascertainment of adult cases in the laboratory reporting system by a factor of 20.

    Absence due to illness among children in 24 daycare centres in Copenhagen was registered during two periods of one year each with a five year interval. The results from the first period have been reported earlier. In each period, the physical, environmental, hygienic and social conditions of the institutions were assessed, and the playroom area per child was registered. The total number of children increased from 855 in the first period to 921 in the second because 13 of the 24 institutions had increased their capacity in the intervening period. On average, the playroom area per child decreased with 0.27 square metre per child in the 13 institutions with an increased number of children. All children were less than three years of age. Absence due to sickness constituted 7.6% of the days during which the institutions were open. For the second period, where the childrens age had been exactly registered, the effect of age on absence due to sickness was found to be statistically significant. The direction of the effect was a decrease in illness with increasing age. However, due to a high correlation between age and time attending the institution, the effect of age could not be separated from the similar effect of length of time that the child had attended the institution. It was found that sickness will decrease with 7.8% per month that the age of the child and time attending the institution is increased. A statistically significant connection was found between the playroom area per child and absence due to sickness after correction for the influence of age in a multivariate analysis. In conclusion, the sickness will decrease with 10.8% per square metre the playroom area per child is increased.

    The Copenhagen Burnout Inventory (CBI) is a public domain questionnaire measuring the degree of psychological fatigue experienced in three subdimensions of Burnout: personal (PB), work-related (WB), and client-related Burnout (CB). The study aimed to examine the acceptability, reliability and construct validity of the Spanish version of CBI. The study population consisted of 479 workers of educational centers, social work centres, healthcare centres and workers within the industry sector. Data was collected in 2009 through a self-administered questionnaire including the three CBI scales, sixteen scales of psychosocial work environment (COPSOQ ISTAS21) and perceived general and mental health and vitality (SF-36). Response rate was 78.7%. The three scales have an inter-item correlation average between 0.42 and 0.60 and a corrected item-total correlation between 0,49 and 0,83. The internal consistency of the three scales had Cronbach's α values of 0.90 for PB, 0.83 for WB and 0.82 for CB. Burnout was related to both psychosocial work environment and wellbeing measures in the expected direction and intensity. The items of the three scales show good discrimination capacity, good consistency and homogeneity. The three CBI scales have an acceptable internal consistency reliability index, slightly higher in PB. The discrimination capacity of the scales is verified through the discrimination index and the different levels between occupations and activities. These results demonstrate that the Spanish version of the CBI is a reliable and valid instrument for measuring Burnout.

    To determine minimally important differences (MIDs) for scales in the first version of the Copenhagen Psychosocial Questionnaire (COPSOQ). Data were taken from two separate studies: a national population survey (N = 1062), and an intervention study at 14 workplaces (N = 1505). On the basis of the population survey, the MID for each COPSOQ scale was calculated as one-half of a standard deviation (0.5 SD). For the core COPSOQ scales on ''Quantitative demands'', ''Influence at work'', ''Predictability'', ''Social support (from colleagues and supervisors, respectively)'', and ''Job satisfaction'', the MIDs were evaluated in the intervention study, where score differences for the scales were linked to the respondents' global self-evaluation of the impact of the interventions. The scales were scored from 0 to 100 in both studies. The MIDs calculated as 0.5 SD were, on average, 9.2 (range 6.8-14.9) for the long version scales, and 10.8 (range 7.6-14.9) for the medium-length version scales. The analysis of the self-evaluated changes on the scale scores for the core COPSOQ scales showed that the anchor-based estimates of MID were generally lower than 0.5 SD. We recommend the following MID values for the COPSOQ scales: ''Quantitative demands'', 0.3 SD; ''Influence'', 0.2 SD; ''Predictability'', 0.3 SD; ''Social support from colleagues'', 0.3 SD; ''Social support from supervisor'', 0.7 SD; and ''Job satisfaction'', 0.4 SD. For all other COPSOQ scales, where we do not have anchor-based results, we recommend the conventional MID value of 0.5 SD.

    There is an ongoing debate concerning possible disadvantages of mammography screening, one being the consequence of receiving a false positive test-result. It is argued that receiving a false positive answer may have short- and/or long-term adverse psychological effects on women, but results from different studies are conflicting. We tested if there was a difference in continued participation behaviour between the group of women who have been subject to a false positive result and those who have not. The study used the registers from the first six invitation rounds of the mammography screening programme in Copenhagen (1991-2003). We estimated the relative risk of not participating in the subsequent screening round for women with a false positive test using women with a negative test as baseline. As outcome measure odds ratios (OR) with 95% confidence intervals (CI) were used. There was no significant difference in participation in the subsequent round between women with a false positive test and women with a negative test. The proportion of screens resulting in false positive answers, both after assessment and after surgery, decreased from 5.54% in Round 1 to 1.79% in Round 5. Participation in the subsequent screening round was well above 80% in all five screening rounds. Our results showed that women experiencing a false positive test at mammography screening participated in the subsequent screening round to the same extent as did women experiencing a negative screening test, regardless of whether the false positive statement was given following assessment or following surgery. The benign to malignant biopsy ratio, comparing the type B false positives to the true positives, was by the fifth round well below the desirable level of

    Aims The aim of this study was to investigate the impact of persistence and non-persistence in leisure time physical activity on coronary heart disease and all-cause mortality. Methods and results In the Copenhagen City Heart Study, we prospectively followed 12,314 healthy subjects for 33 years of maximum follow-up with at least two repeated measures of physical activity. The association between persistence and non-persistence in leisure time physical activity, coronary heart disease and all-cause mortality were assessed by multivariable Cox regression analyses. Coronary heart disease mortality for persistent physical activity in leisure compared to persistent sedentary activity were: light hazard ratio (HR) 0.76; 95% confidence interval (CI) 0.63-0.92, moderate HR 0.52; 95% CI 0.41-0.67, and high physical activity HR 0.51; 95% CI, 0.30-0.88. The differences in longevity were 2.8 years for light, 4.5 years for moderate and 5.5 years for high physical activity. A substantial increase in physical activity was associated with lower coronary heart disease mortality (HR 0.75; 95% CI 0.52-1.08) corresponding to 2.4 years longer life, whereas a substantial decrease in physical activity was associated with higher coronary heart disease mortality (HR 1.61; 95% CI 1.11-2.33) corresponding to 4.2 years shorter life than the unchanged group. A similar pattern was observed for all-cause mortality. Conclusion We found inverse dose-response relationships between persistent leisure time physical activity and both coronary heart disease and all-cause mortality. A substantial increase in physical activity was associated with a significant gain in longevity, whereas a decrease in physical activity was associated with even greater loss of longevity.

    This study addresses the recent climatology of hail occurrence in the Greater Metropolitan Severe Thunderstorm Warning Area (GMSTWA) of New South Wales, Australia, which is a sprawling suburban area, with a population of nearly 4.7 million and one of Australia's largest metropolis. The main objective is to highlight the recent temporal-spatial fluctuations of hailstone frequencies and magnitudes for each of recognized and vastly inhabited Local Government Areas (LGAs). The relevant hail event data from 1989 to 2013 were initially derived from the severe storm archive of Australian Bureau of Meteorology. A climatologically oriented GIS technique was applied in the examining and mapping procedure of all hail events and hail days reported throughout the study area. By applying a specific criterion, all severe hails (defined as 2 cm or more in diameter) were cautiously selected and then imported into the ArcGIS software for relevant analysis. Appropriate data layers were stored in a unique database to allow logical integration of the data directly into some geoprocessing functions, mainly for querying, analyzing and mapping purposes in a model-builder setting. The database includes 357 hailstones with sizes 2-11 cm and occurred in 169 hail days across the region during the past 25 years. The models have established that hailstones are neither temporally nor spatially uniform in magnitude throughout the study area. Temporal analysis indicated that most of hail events occurred predominately in the afternoons with peak time of 1-5 p.m. EST. They were particularly common in spring and summer, and reached maximum frequency in November and December. There was an average of 14.3 events each year, but a significant decreasing trend in terms of hail frequency and associated magnitude in the recent years has been identified. In turn, spatial models also established three main distribution patterns over the study area, which include the Sydney Metropolitan, coastal and pronounced

    Greater levels of conscientiousness have been associated with lower levels of negative affect. We focus on one mechanism through which conscientiousness may decrease negative affect: effective emotion regulation, as reflected by greater recovery from negative stimuli. In 273 adults who were 35-85 years old, we collected self-report measures of personality including conscientiousness and its self-control facet, followed on average 2 years later by psychophysiological measures of emotional reactivity and recovery. Among middle-aged adults (35-65 years old), the measures of conscientiousness and self-control predicted greater recovery from, but not reactivity to, negative emotional stimuli. The effect of conscientiousness and self-control on recovery was not driven by other personality variables or by greater task adherence on the part of high conscientiousness individuals. In addition, the effect was specific to negative emotional stimuli and did not hold for neutral or positive emotional stimuli.

  15. From correspondence to complementarity: The emergence of Bohr's Copenhagen interpretation of quantum mechanics

    NASA Astrophysics Data System (ADS)

    Tanona, Scott Daniel

    I develop a new analysis of Niels Bohr's Copenhagen interpretation of quantum mechanics by examining the development of his views from his earlier use of the correspondence principle in the so-called 'old quantum theory' to his articulation of the idea of complementarity in the context of the novel mathematical formalism of quantum mechanics. I argue that Bohr was motivated not by controversial and perhaps dispensable epistemological ideas---positivism or neo-Kantianism, for example---but by his own unique perspective on the difficulties of creating a new working physics of the internal structure of the atom. Bohr's use of the correspondence principle in the old quantum theory was associated with an empirical methodology that used this principle as an epistemological bridge to connect empirical phenomena with quantum models. The application of the correspondence principle required that one determine the validity of the idealizations and approximations necessary for the judicious use of classical physics within quantum theory. Bohr's interpretation of the new quantum mechanics then focused on the largely unexamined ways in which the developing abstract mathematical formalism is given empirical content by precisely this process of approximation. Significant consistency between his later interpretive framework and his forms of argument with the correspondence principle indicate that complementarity is best understood as a relationship among the various approximations and idealizations that must be made when one connects otherwise meaningless quantum mechanical symbols to empirical situations or 'experimental arrangements' described using concepts from classical physics. We discover that this relationship is unavoidable not through any sort of a priori analysis of the priority of classical concepts, but because quantum mechanics incorporates the correspondence approach in the way in which it represents quantum properties with matrices of transition probabilities, the

    Conflicting evidence has been found regarding the association between high tobacco consumption and body weight among smokers. We tested the hypothesis that high tobacco consumption is causally associated with low body weight. We conducted a Mendelian randomization study with a genetic variant in CHRNA3 (rs1051730) as proxy for high tobacco consumption. The cohort consisted of 80,342 participants from the Copenhagen General Population Study, with details on body weight, smoking habits and CHRNA3 genotype, including 15,220 current smokers. In observational analyses, high tobacco consumption was associated with high body weight, body mass index, waist circumference, hip circumference and waist-hip ratio. In multivariable adjusted models a 1-cigarette/day higher tobacco consumption was associated with 0.05 kg (95% confidence interval 0.02; 0.08) higher body weight, 0.02 kg/m(2) (0.01; 0.02) higher body mass index, 0.10 cm (0.07; 0.12) higher waist circumference and 0.02 cm (0.001; 0.03) higher hip circumference. In contrast, the per-allele increase inCHRNA3 rs1051730 associated with high tobacco consumption was associated with 0.59 kg (0.96; 0.22) lower body weight, 0.23 kg/m(2) (0.33; 0.13) lower body mass index, 0.32 cm (0.74; 0.003) lower waist circumference and 0.45 cm (0.66; 0.24) lower hip circumference. No association was found between tobacco consumption and waist-hip ratio in genetic analysis, or among CHRNA3 genotype and any of the outcome variables in former or never smokers. High tobacco consumption causes lower body weight among current smokers. However, smoking does not seem to affect body shape or fat distribution causally. The lack of association between CHRNA3 genotype and body weight among former smokers and never smokers favours smoking as the causal factor for the observed associations. © The Author 2015; all rights reserved.

  17. Assessing the geologic evolution of Greater Thaumasia, Mars

    The Greater Thaumasia region consists of three chemical provinces that include Syria, Solis, and Thaumasia Planae, the Corprates Rise, part of the Thaumasia Highlands, and the transition zone northwest of the Argyre basin. Chemical signatures obtained from the Mars Odyssey Gamma Ray Spectrometer suggest low abundances of K and Th to the west, with low H abundances and high Si abundances to the east, relative to the bulk Martian crust at midlatitudes. These observations are confirmed and quantified with a modified box and whisker analysis that simultaneously captures the degree of deviation and significance of the regionally anomalous chemistry. Motivated by regionally unique chemistry, as well as its diverse geological history, we characterize Greater Thaumasia in terms of chemistry, mineralogy, and mapped geology to determine how such complementary data record the evolution of this region. Our observations are inconsistent with a proposed salt-lubricated landslide origin, particularly given the lack of chemical or mineralogical signatures to support near-surface salt deposits that should arise over geological timescales. Our observations instead support magmatic processes, such as mantle evolution over geological time, which may impart the Si-enriched signature of the eastern portion of Greater Thaumasia as well as the K and Th depletion of the southeastern flank of Syria Planum. While the observed trend of decreasing K and Th from Noachian to Hesperian lavas is inconsistent with previous models of Martian mantle evolution, we see an increase in Ca content at the Noachian-Hesperian boundary, consistent with predictions from thermodynamic modeling.

    This analysis of the Copenhagen Accord evaluates emission reduction pledges by individual countries against the Accord's climate-related objectives. Probabilistic estimates of the climatic consequences for a set of resulting multi-gas scenarios over the 21st century are calculated with a reduced complexity climate model, yielding global temperature increase and atmospheric CO2 and CO2-equivalent concentrations. Provisions for banked surplus emission allowances and credits from land use, land-use change and forestry are assessed and are shown to have the potential to lead to significant deterioration of the ambition levels implied by the pledges in 2020. This analysis demonstrates that the Copenhagen Accord and the pledges made under it represent a set of dissonant ambitions. The ambition level of the current pledges for 2020 and the lack of commonly agreed goals for 2050 place in peril the Accord's own ambition: to limit global warming to below 2 °C, and even more so for 1.5 °C, which is referenced in the Accord in association with potentially strengthening the long-term temperature goal in 2015. Due to the limited level of ambition by 2020, the ability to limit emissions afterwards to pathways consistent with either the 2 or 1.5 °C goal is likely to become less feasible.

  19. The State of Lithospheric Stress in Greater Thailand

    Thailand and its surrounding regions occupy an important, but often overlooked, location in terms of plate tectonics and lithospheric deformation. The lateral extrusion of Tibet southeastward and eastward along deep strike slip faults to the north and the Sumatra-Andaman subduction zone to the south and west bound the region of greater Thailand. While it is adjacent to some of the most seismically active plate boundaries and intra-plate regions on Earth, this region has experienced only a low level of background seismicity. Thus, the long-term seismic potential of greater Thailand remains highly uncertain. Although historic seismicity is one indicator for future seismicity it is not the only tool we have for determining seismic hazard; we can assess the state of lithospheric stress. The stress conditions in this apparent aseismic region will be controlled by the forces acting on it boundaries. We can analyze those conditions through a study of fault structure, earthquake activity, and kinematics in the boundary area. Using Global Seismic Network (GSN) data augmented with Thai seismic network data to constrain the kinematics, and numerical finite element modeling of crustal and lithospheric deformation of the region, we are able to determine to overall stress conditions. This stress model can be compared to the known fault states in Thailand to assess the potential for earthquake activity.

    The phylogeography of the bush habituated African bovid species impala (Aepyceros melampus) and greater kudu (Tragelaphus strepsiceros) is investigated using mitochondrial DNA (mtDNA) markers. Combined analysis of individual lineages, relationships and population genetics suggest a colonization process from Southern Africa toward Eastern regions in the greater kudu. Results are less clear for the impala, although remaining consistent with a similar pattern of historical dispersion. The study reveals a similar pattern, that is a marked divergence of lineages from South-western Africa relative to other regions. This pattern is opposed to previously published findings in other African bovid species. In the impala, the genetically isolated region is consistent with morphology because it is recognized as the subspecies A. m. petersi, the black-faced impala. In contrast, the similar split of South-western mitochondrial lineages was not expected in the greater kudu on the basis of morphology. Both species show a significant population genetic differentiation. Beyond their phylogeographical value, our results should raise conservation concerns about South-western populations of both species. The black-faced impala is categorized as vulnerable and our data show indications of hybridization with common impala A. m. melampus. The previously unrecognized genetic status of the South-western kudus could also imply conservation regulations.

    2015-05-01

    Lower limb traction apophysitis is common in young athletes, occurring at sites such as the tibial tubercle (Osgood-Schlatter disease) and distal patella (Sinding-Larsen-Johansson disease). Around the hip, iliac apophysitis is well recognized, but no cases of greater trochanter apophysitis have previously been reported. We describe the case of a 15-year-old male basketball player with a 2-month history of the right hip pain and significant functional limitation. X-rays revealed widening of the greater trochanter apophysis with subchondral sclerosis, consistent with a diagnosis of traction apophysitis. The patient was treated with a period of relative rest and anti-inflammatory medication. He gradually returned to full athletic activity, including basketball, without recurrence of pain or limitation. We describe the first reported case of traction apophysitis of the greater trochanter. The unique muscular anatomy of this apophysis with balanced forces explains the rarity of this condition. If encountered, rest and activity modification is the recommended treatment.

    Familiarity with the structure and composition of normal tissue and an understanding of the changes that occur during disease is pivotal to the study of the human body. For decades, microscope slides have been central to teaching pathology in medical courses and related subjects at the University of Copenhagen. Students had to learn how to use a microscope and envisage three-dimensional processes that occur in the body from two-dimensional glass slides. Here, we describe how a PathXL virtual microscopy system for teaching pathology and histology at the Faculty has recently been implemented, from an administrative, an economic, and a teaching perspective. This fully automatic digital microscopy system has been received positively by both teachers and students, and a decision was made to convert all courses involving microscopy to the virtual microscopy format. As a result, conventional analog microscopy will be phased out from the fall of 2016. PMID:28382225

    Despite the avalanche of empirical data on prodromal/”at risk” conditions, the essential aspects of the vulnerability to the schizophrenia spectrum remain largely unaddressed. We report here the results of the Copenhagen Schizophrenia Prodromal Study, a prospective, observational study of first admission patients in putative state of beginning psychosis (N=151) with a follow-up length of 60 months. At follow-up, the rate of conversion to schizophrenia spectrum diagnosis was 37%, whereas the conversion rate from schizotypal disorder to schizophrenia was 25%. High levels of perplexity and self-disorders baseline scores yielded the best prediction of the subsequent development of schizophrenia spectrum disorders. Escalating transitions within the spectrum (i.e., from schizotypal disorder to schizophrenia) were not associated to any candidate psychopathological predictor. PMID:21991279

    OBJECTIVE--To estimate the influence of plasma total cholesterol, high density lipoprotein cholesterol, and triglycerides on risk of cerebrovascular disease. DESIGN--The Copenhagen City Heart Study is a prospective observational survey with two cardiovascular examinations at five year intervals. Non-fasting plasma lipids were measured in participants once at each examination, along with other variables. The Cox regression model was used to establish the effect of the factors recorded on cerebrovascular events of mostly, but not exclusively, ischaemic origin. SUBJECTS--19,698 women and men at least 20 years old, randomly selected after age stratification from an area of central Copenhagen. MAIN OUTCOME MEASURES--Initial cases of stroke and transient ischaemic attack recorded from hospital records and death certificates from 1976 through 1988. RESULTS--660 non-haemorrhagic and 33 haemorrhagic events were recorded. Total cholesterol was positively associated with risk of non-haemorrhagic events, but only for levels > 8 mmol/l, corresponding to the upper 5% of the distribution in the study population. For lower plasma cholesterol values the relative risk remained nearly constant. Plasma triglyceride concentration was significantly, positively associated with risk of non-haemorrhagic events. The relative risk corresponding to an increase of 1 mmol/l was 1.12 (95% confidence interval 1.07 to 1.16). There was a negative, log linear association between high density lipoprotein cholesterol and risk of non-haemorrhagic events (0.53 (0.34 to 0.83)). There was no indication that the effects of plasma lipids were different in women and men. CONCLUSIONS--The pattern of the association between plasma cholesterol and risk of ischaemic cerebrovascular disease was not log linear, and the increased risk was confined to the upper 5% of the cholesterol distribution. Further studies should concentrate on the association between plasma cholesterol and verified haemorrhagic stroke. PMID

    Individual stature depends on multifactorial causes and is often used as a proxy for investigating the biological standard of living. While the majority of European studies on 19th and 20th century populations are based on conscript heights, stature derived from skeletal remains are scarce. For the first time in Denmark this study makes a comparison between skeletal stature and contemporary Danish conscript heights and investigates stature of males and females temporally and between socially distinct individuals and populations in 19th and early 20th century Copenhagen. A total of 357 individuals (181 males, 176 females) excavated at the Assistens cemetery in Copenhagen is analyzed. Two stature regression formulae (Trotter, 1970; Boldsen, 1990) are applied using femur measurements and evaluated compared to conscript heights. The results indicate that mean male stature using Boldsen follows a similar trend as the Danish conscript heights and that Trotter overestimate stature by ca. 6cm over Boldsen. At an inter population level statistically significant differences in male stature are observed between first and second half of the 19th century towards a slight stature decrease and larger variation while there are no significant changes observed in female stature. There are insignificant differences in stature between middle and high class individuals, but male stature differs statistically between cemeteries (p=0.000) representing middle/high class, paupers and navy employees, respectively. Female stature had no significant wealth gradient (p=0.516). This study provides new evidence of stature among males and females during the 19th century and suggests that males may have been more sensitive to changes in environmental living and nutrition than females.

  1. Distribution of Permo-Carboniferous clastics of Greater Arabian basin

    Strikingly correlative sequences of sediments composed of sandstones, siltstones, shales, and thin argillaceous carbonate beds are present, practically everywhere, underlying the Late Permian carbonates in the Greater Arabian basin. The Greater Arabian basin as defined here occupies the broad Arabian Shelf that borders the Arabian shield. This basin is composed of several smaller basins. These clastics are exposed as thin bands and scattered small exposures in several localities around the margins of the basin. The Permo-Carboniferous clastics are represented by the Unayzah Formation of Arabia, the Doubayat Group of Syria, the Hazro Formation of southeast Turkey, the Ga'arah Formation of Iraq, the Faraghan Formation of southwest Iran, and the Haushi Group of Oman. A Late Carboniferous-Early Permian age is assigned to these clastics because they contain fossil plants and palynomorphs. These sediments represent time-transgressive fluctuating sea deposits following a phase of regional emergence, erosion, and structural disturbance which preceded the Permian transgression. The basal contact of these clastics is marked by a well-pronounced angular unconformity with various older units, ranging in age from early Carboniferous to late Precambrian. This regional unconformity is probably related to the Hercynian movements. The upper contact is conformable with the Permian carbonates. The porous sandstones of the Permo-Carboniferous sediments are important hydrocarbon exploration targets. These reservoir rocks sometimes overlie mature source rocks and are capped by shales, marls, and tight carbonates. Significant quantities of hydrocarbons are contained in these reservoirs in different parts of the Greater Arabian basin.

    The condition of the sagebrush ecosystem has been declining in the Western United States, and greater sage-grouse (Centrocercus urophasianus), a sagebrush-obligate species, has experienced concurrent decreases in distribution and population numbers. This has prompted substantial research and management over the past two decades to improve the understanding of sage-grouse and its habitats and to address the observed decreases in distribution and population numbers. The amount of research and management has increased as the year 2015 approaches, which is when the U.S. Fish and Wildlife Service (FWS) is expected to make a final decision about whether or not to protect the species under the Endangered Species Act. In 2012, the Sage-Grouse Executive Oversight Committee (EOC) of the Western Association of Fish and Wildlife Agencies (WAFWA) requested that the U.S. Geological Survey (USGS) lead the development of a Greater Sage-Grouse National Research Strategy (hereafter Research Strategy). This request was motivated by a practical need to systematically connect existing research and conservation plans with persisting or emerging information needs. Managers and researchers also wanted to reduce redundancy and help focus limited funds on the highest priority research and management issues. The USGS undertook the development of this Research Strategy, which addresses information and science relating to the greater sage-grouse and its habitat across portions of 11 Western States. This Research Strategy provides an outline of important research topics to ensure that science information gaps are identified and documented in a comprehensive manner. Further, by identifying priority topics and critical information needed for planning, research, and resource management, it provides a structure to help coordinate members of an expansive research and management community in their efforts to conduct priority research.

    Hybridization of wildlife species, even in the absence of introgression, is of concern due to wasted reproductive effort and a reduction in productivity. In this study we detail an accidental mating between a female nyala (Tragelaphus angasii) and a male greater kudu (T. strepsiceros). The hybrid was phenotypically nyala and was identified as such based on mitochondrial DNA. Further genetic analysis based on nine microsatellite markers, chromosome number and chromosome morphology however, confirmed its status as an F1 hybrid. Results obtained from a reproductive potential assessment indicated that this animal does not have the potential to breed successfully and can be considered as sterile.

    Primary or idiopathic greater omental torsion remains a rare cause of acute surgical abdomen in adults and children. The aetiology is as yet unknown and the treatment of choice, once diagnosis is established, is resection of the torted omentum. We report our experience with three such cases encountered over the last five years, two of which were diagnosed and subsequently managed laparoscopically. The performance of diagnostic laparoscopy for acute abdominal pain of an undetermined origin may lead to an increased detection of this condition and subsequent therapeutic intervention.

    2013-06-01

    We report the characteristics of 115 extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli clinical isolates, from 115 unique Danish patients, over a 1-year study interval (1 October 2008 to 30 September 2009). Forty-four (38%) of the ESBL isolates represented sequence type 131 (ST13)1, from phylogenetic group B2. The remaining 71 isolates were from phylogenetic groups D (27%), A (22%), B1 (10%), and B2 (3%). Serogroup O25 ST131 isolates (n = 42; 95% of ST131) comprised 7 different K antigens, whereas two ST131 isolates were O16:K100:H5. Compared to non-ST131 isolates, ST131 isolates were associated positively with CTX-M-15 and negatively with CTX-M-1 and CTX-M-14. They also were associated positively with 11 virulence genes, including afa and dra (Dr family adhesins), the F10 papA allele (P fimbria variant), fimH (type 1 fimbriae), fyuA (yersiniabactin receptor), iha (adhesin siderophore), iutA (aerobactin receptor), kpsM II (group 2 capsules), malX (pathogenicity island marker), ompT (outer membrane protease), sat (secreted autotransporter toxin), and usp (uropathogenicity-specific protein) and negatively with hra (heat-resistant agglutinin) and iroN (salmochelin receptor). The consensus virulence gene profile (>90% prevalence) of the ST131 isolates included fimH, fyuA, malX, and usp (100% each), ompT and the F10 papA allele (95% each), and kpsM II and iutA (93% each). ST131 isolates were also positively associated with community acquisition, extraintestinal pathogenic E. coli (ExPEC) status, and the O25, K100, and H4 antigens. Thus, among ESBL E. coli isolates in Copenhagen, ST131 was the most prevalent clonal group, was community associated, and exhibited distinctive and comparatively extensive virulence profiles, plus a greater variety of capsular antigens than reported previously.

    Insensible body mass loss (IBL) from the human body continuously occurs, which is an important component in body heat exchange. The purpose of this study was to examine the relevance of IBL to anthropometric characteristics and self-identified thermal tolerance. A total of 289 healthy young Korean males were chosen and sorted into the following three groups: heat tolerable only (HTO, N = 79), cold tolerable only (CTO, N = 104), neither heat nor cold tolerable (NHC, N = 106). They weighed before and after a 30-min rest under lightly clothed condition at an air temperature of 23 ± 1 °C with a relative humidity 55 ± 5 %RH. (1) The IBL of 289 males had a mean of 90 ± 75 g h(-1) (48 ± 40 g h(-1) m(-2)); (2) No significant difference in IBL among the three groups were found; (3) Significant differences in body weight and body mass index (BMI) among three groups were found (P < 0.05), but insignificance was found for height (P = 0.726) or body surface area (P = 0.059); (4) CTO was approximately 4.1 kg heavier in body weight (P < 0.05) and higher in BMI (P < 0.01) than in HTO; (5) Only for the group CTO, IBL (g h(-1)) showed a positive relationship to BMI (P < 0.05, R (2) = 0.056), but there was no relationship between IBL and body surface area. For healthy young males within normal anthropometric ranges in Korea, IBL was positively related to BMI, and individuals with greater BMI showed greater self-identified cold tolerance, but no direct relationship was found between IBL and self-identified cold tolerance. This suggests that body physique (e.g., BMI) could be an explanatory factor between insensible body heat loss and subjective cognition on cold tolerance.

    Among immigrants resident in greater London from Europe, Ireland, the USSR, the old Commonwealth countries of Australia, Canada, and New Zealand, North and South America, Egypt, Turkey, and Iran the incidence of admission to hospital for probable multiple sclerosis (MS) between 1960 and 1972 was high or moderately high. The incidence was the same order as that found in those born in the United Kingdom. Immigrants from India, Pakistan, and other Asian countries and from new Commonwealth Africa and America, which includes the West Indies, had a low incidence of hospital admission for MS. Immigrants from countries where the risk of MS is low whose parents were born in Europe had a reduced incidence of admission to hospital but not the very low incidence found in those parents were also born in these countries. Emigrating to England from low risk parts of the world did not seem to increase the risk of developing MS. PMID:1260384

    This article maps the history of health organisation across Greater Manchester (GM), primarily since the Second World War, to show how against a continuing backdrop of health inequalities, services have been driven (and constrained) by the needs and the politics of each period. Defining ‘success’ as benefits for patients the article identifies examples such as Salford’s mental health services (1950s and 1960s), public health in North Manchester (1970s and 1980s), the creation of centres for diabetes, sickle-cell and thalassaemia (1980s) and the formation of the Joint Health Unit in 2002. What this history shows is that over the period the common factors influencing the ‘success’ of health organisation across GM have been the championing of particular issues by multi-disciplinary groups working across health and social care and stability in structures and personnel.

  11. Multisensor Arrays for Greater Reliability and Accuracy

    2004-01-01

    Arrays of multiple, nominally identical sensors with sensor-output-processing electronic hardware and software are being developed in order to obtain accuracy, reliability, and lifetime greater than those of single sensors. The conceptual basis of this development lies in the statistical behavior of multiple sensors and a multisensor-array (MSA) algorithm that exploits that behavior. In addition, advances in microelectromechanical systems (MEMS) and integrated circuits are exploited. A typical sensor unit according to this concept includes multiple MEMS sensors and sensor-readout circuitry fabricated together on a single chip and packaged compactly with a microprocessor that performs several functions, including execution of the MSA algorithm. In the MSA algorithm, the readings from all the sensors in an array at a given instant of time are compared and the reliability of each sensor is quantified. This comparison of readings and quantification of reliabilities involves the calculation of the ratio between every sensor reading and every other sensor reading, plus calculation of the sum of all such ratios. Then one output reading for the given instant of time is computed as a weighted average of the readings of all the sensors. In this computation, the weight for each sensor is the aforementioned value used to quantify its reliability. In an optional variant of the MSA algorithm that can be implemented easily, a running sum of the reliability value for each sensor at previous time steps as well as at the present time step is used as the weight of the sensor in calculating the weighted average at the present time step. In this variant, the weight of a sensor that continually fails gradually decreases, so that eventually, its influence over the output reading becomes minimal: In effect, the sensor system "learns" which sensors to trust and which not to trust. The MSA algorithm incorporates a criterion for deciding whether there remain enough sensor readings that

    The islands of the Greater Antilles exhibit differing pre-Oligocene tectonic styles and histories, but all display the results of convergent plate activity from the Early Cretaceous to the Middle Eocene. Western and central Cuba consist of autochthonous, Jurassic and older continental crust, which was overthrust by Cretaceous ophiolites in the Early to Middle Eocene. In contrast, eastern Cuba seems to be similar to Northern Hispaniola, and both areas consist of complexes of upper Cretaceous to Eocene magmatic-arc rocks, and trench generated ophiolites and blueschists produced by SW directed subduction. The oldest rocks in central Hispaniola are exposed in NW trending linear fault-bounded belts. Unusual high-Mg greenschists and amphibolites, quartz-feldspathic greenschists, together with N-type MORB basalts and keratophyric volcanics, are juxtaposed against a medial serpentinite belt. Central and eastern Puerto Rico consist of Lower to Upper Cretaceous volcanic rocks intruded by upper Cretaceous to Eocene plutons. Similar Cretaceous volcanics occur in SW Puerto Rico, but they are overthrust by Upper Jurassic cherts, spilites and amphibolites. Jamaica lies along the Nicaraguan Rise to the SW of the other islands and consists of Barremian to Maastrichtian volcanics and volcanogenic sediments intruded by upper Cretaceous calc-alkalic plutons. Blueschists and related rocks in eastern Jamaica, and geochemical zonation in the igneous rocks suggest that the subduction was to the NW. Change in tectonic movements from convergence to left lateral shear took place during the Late Eocene/Early Oligocene.

    1997-10-01

    The Greater Green River Basin (GGRB) of Wyoming has produced abundant oil and gas out of multiple reservoirs for over 60 years, and large quantities of gas remain untapped in tight gas sandstone reservoirs. Even though GGRB production has been established in formations from the Paleozoic to the Tertiary, recent activity has focused on several Cretaceous reservoirs. Two of these formations, the Ahnond and the Frontier Formations, have been classified as tight sands and are prolific producers in the GGRB. The formations typically naturally fractured and have been exploited using conventional well technology. In most cases, hydraulic fracture treatments must be performed when completing these wells to to increase gas production rates to economic levels. The objectives of the GGRB production improvement project were to apply the concept of horizontal and directional drilling to the Second Frontier Formation on the western flank of the Rock Springs Uplift and to compare production improvements by drilling, completing, and testing vertical, horizontal and directionally-drilled wellbores at a common site.

    Herbal hepatotoxicity is a rare and poorly described disease because reported cases are mostly scattered and lack an appropriate causality assessment. We now describe in detail the clinical picture of herbal hepatotoxicity by extracts of Greater Celandine (GC), syn. Chelidonium majus L. from the Papaveraceae family, which contain more than 20 ingredients including various biologically active isoquinoline alkaloids. For this purpose, we analyzed and reviewed published cases of 16 patients from various European countries. In all patients, herbal hepatotoxicity was of probable and highly probable causality for GC, using the original and updated scale of CIOMS (Council for International Organizations of Medical Sciences). GC associated hepatotoxicity usually has an acute clinical course exhibiting a hepatocellular pattern of injury and is correlated to an idiosyncratic reaction with its metabolic subtype. Jaundice combined with high values of serum aminotransferases was present in virtually all cases with favourable outcome despite severe clinical course. In conclusion, GC hepatotoxicity is a typical herbal hepatotoxicity with a sound causality track for GC, but there is uncertainty regarding the respective causative compound(s). The present detailed review of GC hepatotoxicity may serve as an example for clinical causality assessments of future cases of liver injury due to other herbs.

    Recent estimates of the natural gas resources of Cretaceous low-permeability reservoirs of the Greater Green River basin indicate that as much as 5000 trillion cubic feet (Tcf) of gas may be in place (Law and others 1989). Of this total, Law and others (1989) attributed approximately 80 percent to the Upper Cretaceous Mesaverde Group and Lewis Shale. Unfortunately, present economic conditions render the drilling of many vertical wells unprofitable. Consequently, a three-well demonstration program, jointly sponsored by the US DOE/METC and the Gas Research Institute, was designed to test the profitability of this resource using state-of-the-art directional drilling and completion techniques. DOE/METC studied the geologic and engineering characteristics of ``tight`` gas reservoirs in the eastern portion of the Greater Green River basin in order to identify specific locations that displayed the greatest potential for a successful field demonstration. This area encompasses the Rocks Springs Uplift, Wamsutter Arch, and the Washakie and Red Desert (or Great Divide) basins of southwestern Wyoming. The work was divided into three phases. Phase 1 consisted of a regional geologic reconnaissance of 14 gas-producing areas encompassing 98 separate gas fields. In Phase 2, the top four areas were analyzed in greater detail, and the area containing the most favorable conditions was selected for the identification of specific test sites. In Phase 3, target horizons were selected for each project area, and specific placement locations were selected and prioritized.

    The Greater Platte River Basins (GPRB), located in the heartland of the United States, provides a collaborative opportunity for the U.S. Geological Survey (USGS) and its partners to understand the sustainability of natural and managed ecosystems under changing climate and resource requirements.The Greater Platte River Basins, an area of about 140,000 square miles, sustains thousands of acres of lakes and wetlands, which provide a staging and resting area for the North American Central Flyway. Part of the GPRB is within the U.S. Corn Belt, one of the most productive agricultural ecosystems on Earth. Changes in water and land use, changing patterns of snowmelt in the Rocky Mountains, drought, and increasing demands for irrigation have reduced flows in the Platte River. These changes raise questions about the sustainability of the region for both wildlife and agriculture.The USGS and partners are developing a science strategy that will help natural-resource managers address and balance the needs of this region.

    Poor adherence is the main barrier to the effectiveness of HIV medication. The objective of this study was to explore and conceptualize patterns and difficulties in physicians' work with patients' adherence to HIV medication. No previous studies on this subject have directly observed physicians' behavior. This is a qualitative, cross-sectional study. We used a Grounded Theory approach to let the main issues in physicians' work with patients' adherence emerge without preconceiving the focus of the study. We included physicians from HIV clinics in San Francisco, U.S.A. as well as from Copenhagen, Denmark. Physicians were observed during their clinical work and subsequently interviewed with a semi-structured interview guide. Notes on observations and transcribed interviews were analyzed with NVivo software. We enrolled 16 physicians from San Francisco and 18 from Copenhagen. When we discovered that physicians and patients seldom discussed adherence issues in depth, we made adherence communication and its barriers the focus of the study. The main patterns in physicians' communication with patients about adherence were similar in both settings. An important barrier to in-depth adherence communication was that some physicians felt it was awkward to explore the possibility of non-adherence if there were no objective signs of treatment failure, because patients could feel "accused." To overcome this awkwardness, some physicians consciously tried to "de-shame" patients regarding non-adherence. However, a recurring theme was that physicians often suspected non-adherence even when patients did not admit to have missed any doses, and physicians had difficulties handling this low believability of patient statements. We here develop a simple four-step, three-factor model of physicians' adherence communication. The four steps are: deciding whether to ask about adherence or not, pre-questioning preparations, phrasing the question, and responding to the patient's answer. The three

    Near surface geophysics applications are gaining more widespread use in geotechnical and engineering projects. The development of data acquisition, processing tools and interpretation methods have optimized survey time, reduced logistics costs and increase results reliability of seismic surveys during the last decades. However, the use of wide-scale geophysical methods under urban environments continues to face great challenges due to multiple noise sources and obstacles inherent to cities. A seismic pre-investigation was conducted to investigate the feasibility of using seismic methods to obtain information about the subsurface layer locations and media properties in Copenhagen. Such information is needed for hydrological, geotechnical and groundwater modeling related to the Cityringen underground metro project. The pre-investigation objectives were to validate methods in an urban environment and optimize field survey procedures, processing and interpretation methods in urban settings in the event of further seismic investigations. The geological setting at the survey site is characterized by several interlaced layers of clay, till and sand. These layers are found unevenly distributed throughout the city and present varying thickness, overlaying several different unit types of limestone at shallow depths. Specific results objectives were to map the bedrock surface, ascertain a structural geological framework and investigate bedrock media properties relevant to the construction design. The seismic test consisted of a combined seismic reflection and refraction analyses of a profile line conducted along an approximately 1400 m section in the northern part of Copenhagen, along the projected metro city line. The data acquisition was carried out using a 192 channels array, receiver groups with 5 m spacing and a Vibroseis as a source at 10 m spacing. Complementarily, six vertical seismic profiles (VSP) were performed at boreholes located along the line. The reflection

    The Carlsberg Fault zone is located in the N-S striking Höllviken Graben and traverses the city of Copenhagen. The fault zone is a NNW-SSE striking structure in direct vicinity to the transition zone of the Danish Basin and the Baltic Shield. Recent small earthquakes indicate activity in the area, although none of the mapped earthquakes appear to have occurred on the Carlsberg Fault. We examined the fault evolution by a combination of very high resolution onshore shear-wave seismic data, one conventional onshore seismic profile and marine reflection seismic profiles. The chalk stratigraphy and the localization of the fault zone at depth was inferred from previous studies by other authors. We extrapolated the Jurassic and Triassic stratigraphy from the Pomeranian Bay to the area of investigation. The fault zone shows a flower structure in the Triassic as well as in Cretaceous sediments. The faulting geometry indicates strong influence of Triassic processes when subsidence and rifting prevailed in the Central European Basin System. Growth strata within the surrounding Höllviken Graben reveal syntectonic sedimentation in the lower Triassic, indicating the opening to be a result of Triassic rifting. In the Upper Cretaceous growth faulting documents continued rifting. This finding contrasts the Late Cretaceous to Paleogene inversion tectonics in neighbouring structures, as the Tornquist Zone. The high-resolution shear-wave seismic method was used to image structures in Quaternary layers in the Carlsberg Fault zone. The portable compact vibrator source ElViS III S8 was used to acquire a 1150 m long seismic section on the island Amager, south of Copenhagen. The shallow subsurface in the investigation area is dominated by Quaternary glacial till deposits in the upper 5-11 m and Danian limestone below. In the shear-wave profile, we imaged the 30 m of the upward continuation of the Carlsberg Fault zone. In our area of investigation, the fault zone appears to comprise

    Particle size distribution (size-range 3-900nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in September-November 2002. The study investigates the contribution from urban versus regional sources of particle number and mass concentration.

    The total particle number (ToN) and NOx are well correlated at the urban and near-city level and show a distinct diurnal variation, indicating the common traffic source. The average ToN at the three stations differs by a factor of 3. The observed concentrations are 2500#cm-3, 4500#cm-3 and 7700#cm-3 at rural, near-city and urban level, respectively.

    PM10 and total particle volume (ToV) are well correlated between the three different stations and show similar concentration levels, in average within 30% relative difference, indicating a common source from long-range transport that dominates the concentrations at all locations.

    Measures to reduce the local urban emissions of NOx and ToN are likely to affect both the street level and urban background concentrations, while for PM10 and ToV only measurable effects at the street level are probable. Taking into account the supposed stronger health effects of ultrafine particles reduction measures should address particle number emissions.

    The traffic source contributes strongest in the 10-200nm particle size range. The maximum of the size distribution shifts from about 20-30nm at kerbside to 50-60nm at rural level. Particle formation events were observed in the 3-20nm size range at rural location in the afternoon hours, mainly under conditions with low concentrations of pre-existing aerosol particles.

    The maximum in the size distribution of the "traffic contribution" seems to be shifted to about 28nm in the urban location compared to 22nm at

    Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute greater relative changes in thermal balance at colder sites. To test this hypothesis, we examined up to 20 years of...

    Occupational risk of bladder cancer (including papilloma) was investigated as part of a case-referent study in Copenhagen. Occupational histories were obtained on 389 cases and 790 referents drawn at random from the general population of the study area. When persons with missing information were excluded, a total of 371 cases (280 men, 91 women) and 771 referents (577 men, 194 women) were left for analysis. After adjustment for tobacco smoking, age, and sex, significantly increased relative risks were observed for occupation in land transport, in particular bus, taxi, or truck driving. A statistically significant trend was seen with duration of employment in these trades. Based on a logistic regression analysis, a relative risk (RR) of 1.3 was determined for 10 years of employment in the trade. An association was also found for employment in trades undertaking painting (RR = 1.4 for 10 years' employment), and a significant trend emerged for duration of employment. A positive association with employment in the textile and leather industry disappeared after adjustment for tobacco smoking, and no association with duration of employment emerged. No association was found with employment in the chemical, rubber, iron and metal industries or in health services.

    Incidence of various diseases can increase following a flood. We aimed to identify professionals in Copenhagen who became ill after contact with 2 July 2011 floodwater/sediment and determine risks and protective factors associated with illness. We conducted a cohort study of employees engaged in post-flood management activities. Participants completed a questionnaire collecting information about demographics, floodwater/sediment exposure, compliance with standard precautions, and symptoms of illness. Overall, 257 professionals participated, with 56 (22%) cases. Risk of illness was associated with not washing hands after floodwater/sediment contact [relative risk (RR) 2∙45], exposure to floodwater at work and home (RR 2∙35), smoking (RR 1∙92), direct contact with floodwater (RR 1∙86), and eating/drinking when in contact with floodwater (RR 1∙77). Professionals need to follow standard precautions when in contact with floodwater/sediment, especially proper hand hygiene after personal protective equipment use and before eating/drinking and smoking.

    Background: The Copenhagen Psychosocial Questionnaire (COPSOQ) is a widely used tool for evaluation of psychosocial risk factors at work. The aims of this study were to describe the short version of Farsi COPSOQ and to present its psychometric properties. Methods: A total of 427 administrative health care staff participated in this descriptive methodological study. Forward–backward procedure was adopted to translate the questionnaire from English into Farsi. Content validity was assessed by a panel of 10 experts. Construct validity was evaluated by exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were assessed using Cronbach’s α and intraclass correlation coefficient(ICC), respectively. The feasibility was assessed using ceiling and floor effect. Results: The short version of Farsi COPSOQ was configured with 16 dimensions (32 items).Content validity of the questionnaire was established. Factor analysis supported the conceptual multi-dimensionality (four factors), and therefore confirmed the construct validity of the Farsi COPSOQ. The internal consistency (Cronbach’s α ranging between 0.75 and 0.89) and test retest reliability (ICC values ranged from 0.75 to 0.89) were both approved and the results showed no ceiling or floor effect. Conclusion: The results support the use of Farsi COPSOQ for evaluation of psychological risks and for research purposes in Iranian population. PMID:28058236

    To characterize physical and mental health in trauma exposed refugees by describing a population of patients with regard to background, mental health history and current health problems; and to identify pre- and post-migratory predictors of mental health. All patients receiving treatment at the Psychiatric Trauma Clinic for Refugees in Copenhagen from April 2008 to February 2010 completed self-rating inventories on symptoms of PTSD, depression and anxiety as well as level of functioning and quality of life before treatment. Then, associations of pre and post migratory factors with mental health were explored using linear and logistic regression and Pearson's correlation coefficients. Among the patients, the prevalence of depression, somatic disease, pain, psychotic symptoms co-existing with PTSD and very low level of functioning was high. Persecution, being an ex-combatant and living currently in social isolation were significantly associated with PTSD arousal symptoms and self-reported pain. New treatment modalities should seek to address all of the symptoms and challenges of the patients including psychotic and somatic symptoms and social isolation, and studies of treatment effect should clarify all co-morbidities so that comparable populations can be included in treatment evaluation studies.

    Scabies and syphilis was very common but social unaccepted diseases in the later part of the 19th century. In 1892, 1,210 patients with syphilis and 106 children suffering from scabies were treated at the Kommunehospital in Copenhagen. Case records from patients admitted March 19th and September 19th, form the study basis of different aspects of scabies and syphilis treatment in the period. In the mid 19th century different soap treatments were the common cure for scabies. In the 1880s the cure became napthollinement, powdering with flour followed by rapping the patient in a sheet. Throughout the whole period experiments with medicine and thereby the patients was the norm. The treatment of syphilis consisted of different forms of mercury cures combined with bathes. Admission time was long and the patient was rarely cured. Progress in the treatments of both diseases was made in the daily work with patients. Access to knowledge, economy, the effort of the physician and the relationship between the different professions and groups in the hospital influenced and formed the process.

    Sick leave among the children in 24 day nurseries in Copenhagen was registered during a period of one year. The physical, environmental and hygienic conditions of the institutions were assessed by means of interviews and inspection, supplemented by information from the local authorities. Sick leave constitutes 7.5% of the days during which the institutions were open and the average number of sick days per child varied from 14.6 to 24.4. Comparisons with similar investigations are inclusive on account of variations in the methods of registration and age distributions. It was characteristic of the institutions investigated that these included a number of old institutions in flats, many in streets with considerable traffic and where the conditions of ventilation and space do not conform with present-day standards. In some of the institutions, the hygiene is unsatisfactory, particularly where ventilation, outdoor activities and hand-washing are concerned. A statistically significant connection was found between amount of traffic at the institution, the hygiene and playroom area per child, on one hand, and absence due to sickness, on the other, as assessed by a statistical model for sick leave for child in a given institution. In order to prevent sickness, it is concluded that efforts to improve hygiene and space are desirable and, similarly, further research concerning the effects of atmospheric pollution is relevant.

    Notwithstanding the general interest and the geopolitical importance of the island countries in the Greater Antilles, little is known about the specific ancestral Native American and African populations that settled them. In an effort to alleviate this lacuna of information on the genetic constituents of the Greater Antilles, we comprehensively compared the mtDNA compositions of Cuba, Dominican Republic, Haiti, Jamaica and Puerto Rico. To accomplish this, the mtDNA HVRI and HVRII regions, as well as coding diagnostic sites, were assessed in the Haitian general population and compared to data from reference populations. The Taino maternal DNA is prominent in the ex-Spanish colonies (61.3%-22.0%) while it is basically non-existent in the ex-French and ex-English colonies of Haiti (0.0%) and Jamaica (0.5%), respectively. The most abundant Native American mtDNA haplogroups in the Greater Antilles are A2, B2 and C1. The African mtDNA component is almost fixed in Haiti (98.2%) and Jamaica (98.5%), and the frequencies of specific African haplogroups vary considerably among the five island nations. The strong persistence of Taino mtDNA in the ex-Spanish colonies (and especially in Puerto Rico), and its absence in the French and English excolonies is likely the result of different social norms regarding mixed marriages with Taino women during the early years after the first contact with Europeans. In addition, this article reports on the results of an integrative approach based on mtDNA analysis and demographic data that tests the hypothesis of a southward shift in raiding zones along the African west coast during the period encompassing the Transatlantic Slave Trade.

    Neuroimaging studies implicate the subgenual anterior cingulate cortex (sgACC) as a critical brain region in adult depression. However, unlike adult depression, little is known about the underlying neural substrates of adolescent depression, and there are no published data examining differences in sgACC activation between depressed and healthy adolescents. This study used functional magnetic resonance imaging to examine sgACC activity in twenty-six depressed and normal 13- to 17-year olds during the performance of a stop-signal task. Significantly greater sgACC activation was found in the depressed adolescents relative to controls. These results establish for the first time abnormal functioning of the sgACC in depressed adolescents and have important implications for understanding the underlying neural correlates and potential treatments of adolescent depression.

    Geotechnical applications such as tunneling, storage of waste, wellbore planning, or reservoir engineering requires detailed 3D information on the rock properties and behavior of the continuum. One of the key parameters is the contemporary crustal in-situ stress state. However, generally the availability of stress data on reservoir scale is scarce or no data exists at all. Furthermore, stress data is often limited to the orientation of the maximum horizontal stress. Hence, geomechanical-numerical modelling provides an approximation of a continuous description of the 3D in-situ stress state. We present a model workflow that shows (1) how to calibrate a regional scale model of Greater Munich with stress orientations and magnitudes mainly from borehole data and (2) how to derive from the regional model boundary conditions for a local high-resolution model of a geothermal reservoir site. This approach using two models is an alternative to the required trade-off between resolution, computational cost and a sufficient number of calibration data which is otherwise inevitable for a single model. The incorporated 3D geological models contain the topography from a digital elevation model and 6 stratigraphic units with different elasto-plastic rock properties. The local model mimics the area of a planned reservoir and its resolution is significantly higher than in the regional model and down to 10 m near the planned borehole trajectories using 21×106 tetrahedron finite elements with linear approximation functions. The uncertainties of the calibrated regional model are large since no information on the magnitude of the maximum horizontal stress is available. Even in the entire Greater Munich area only two reliable leak-off tests that deliver the magnitude of the minimum horizontal stress could be used. These uncertainties are transferred also to the local model. Hence we also show how to quantify for the workflow in general the systematic uncertainties and discuss

    Understanding the mechanisms linking sleep impairment to morbidity and mortality is important for future prevention, but these mechanisms are far from elucidated. We aimed to determine the relation between impaired sleep, both in terms of duration and disturbed sleep, and allostatic load (AL), which is a measure of systemic wear and tear of multiple body systems, as well as with individual risk markers within the cardiac, metabolic, anthropometric, and immune system. A cross-sectional population-based study of 5226 men and women from the Danish Copenhagen Aging and Midlife Biobank with comprehensive information on sleep duration, disturbed sleep, objective measures of an extensive range of biological risk markers, and physical conditions. Long sleep (mean difference 0.23; 95% confidence interval, 0.13, 0.32) and disturbed sleep (0.14; 0.06, 0.22) were associated with higher AL as well as with high-risk levels of risk markers from the anthropometric, metabolic, and immune system. Sub-analyses suggested that the association between disturbed sleep and AL might be explained by underlying disorders. Whereas there was no association between short sleep and AL, the combination of short and disturbed sleep was associated with higher AL (0.19; 0.08, 0.30) and high-risk levels of immune system markers. Our study suggests small but significant differences in the distribution of allostatic load, a pre-clinical indicator of disease risk and premature death, for people with impaired relative to normal sleep. Impaired sleep may be a risk factor for developing disease and be a risk marker for underlying illness or sleep disorders. Copyright © 2014 Elsevier B.V. All rights reserved.

    Hypochondriasis, now often designated as health anxiety, is important in terms of prevalence, levels of suffering, and health services cost in adults. Whereas the DSM-IV-TR suggests that the condition primarily begins in adulthood, retrospective reports point to a possible origin in childhood with onset as early as preschool age. However, little research has addressed health anxiety in children. In the present study we explored parental-reported health anxiety symptoms (HAS) and their association with physical and mental health in a population-based sample of 5- to 7-year-old children. Parents of 1323 children (49.7% boys), recruited from the birth cohort: Copenhagen Child Cohort CCC 2000, completed questionnaires regarding their child's HAS, and physical and mental health. Associations were examined using multiple logistic regression analyses adjusted for concurrent chronic physical disease. HAS were present in 17.6% and present 'a lot' (categorized as considerable HAS) in 2.4% of the children. Children with considerable HAS demonstrated more physical health problems and internalizing disorders than children with no or non-considerable HAS, but in the majority (71.9%) no associated chronic physical disease or other mental disorder was reported. In a subsample of children with functional somatic symptoms (FSS), impairing FSS were more likely among children who reported HAS. The findings suggest that HAS present as primary complaints early in life and are associated with impairing child health problems in the area of FSS and internalizing disorders. These aspects may be important to understand and also to prevent the development of severe health anxiety. Copyright © 2012 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

    We evaluated the physiological response, sprint performance and technical ability in various phases of the Copenhagen Soccer Test for Women (CSTw) and investigated whether the locomotor activities of the CSTw were comparable to competitive match-play (CM). Physiological measurements and physical/technical assessments were performed during CSTw for eleven Norwegian high-level women soccer players. The activity pattern during CSTw and CM was monitored using the ZXY tracking system. No differences were observed between CSTw and CM with regards to total distance covered (10093±94 and 9674±191m), high intensity running (1278±67 and 1193±115m) or sprinting (422±55 and 372±46m) (p>.05). During CSTw, average HR was 85±2%HRmax with 35±2% playing time >90%HRmax. Blood lactate increased (p<.05) from 1.4±0.3mM at rest to an average of 4.7±0.5mM during CSTw, with no changes during the test. Blood glucose was 5.4±0.3mM at rest and remained unaltered during CSTw. Sprint performance (2×20m) decreased (p<.05) by 3% during CSTw (8.19±0.06-8.47±0.10s). In conclusion, the locomotor activities during CSTw were comparable to that of high-level competitive match-play. The physiological demands of the CSTw were high, with no changes in heart rate, blood lactate or technical performance during the test, but a lowered sprint performance towards the end of the test.

    Background Work in dialysis facilities involves long term contact with chronically ill patients. International comparisons make it clear that dialysis work is being concentrated, staff is being reduced and more patients are being treated. It is more than 20 years since the last German publication on job strains and job satisfaction experienced by dialysis staff was published. The present study examines the stress and strain currently experienced by the staff of German dialysis facilities. Methods The staff of 20 dialysis facilities were surveyed with the Copenhagen Psychosocial Questionnaire (COPSOQ). The questionnaire was extended by adding dialysis-specific questions. The data from the dialysis facilities were assessed by comparison with other professions in medical care - nurses and geriatric nurses - using data recorded in the German COPSOQ database. Results A total of 367 employees took part in the study, corresponding to a response rate of 55%. For almost all psychosocial aspects, the dialysis staff regarded the stress and strain as being more critical than did the geriatric nurses. There were some positive differences in comparison to hospital nursing, including less conflict between work and private life. However, there were also negative differences, such as fewer possibilities of influencing the work. Conclusions The results of the study show that dialysis work exhibits both positive and negative aspects in comparison with other healthcare professions. The results in the different facilities were highly variable, indicating that the deficits found in the individual scales are not inevitable consequences of working in dialysis in general, but are influenced and might be favourably altered by the individual facilities.

    Background More attention has been paid to psychosocial conditions as possible risk factors for cardiovascular disease (CVD) and the impact of accumulated major life events (MLE) on the development of CVD has received little attention. Design The aim of this study was to explore the influences of MLE on CVD risk in a large cohort study. Methods The study population consisted of 9542 randomly selected adults free of CVD examined in the Copenhagen City Heart Study in 1991–1994 and followed up for CVD defined as myocardial infarction or ischaemic stroke until 2001. MLE were analysed using an 11-item questionnaire and hazard ratios (HR) were calculated using the Cox proportional hazards model. Results During follow-up there were 443 myocardial infarctions (MI) and 350 ischaemic strokes. Financial problems in both childhood and adulthood were associated with risk of stroke with an HR of 1.71 (95% CI: 1.29–2.26) and 1.60 (1.12–2.30), respectively. Accumulation of MLE was also associated with risk of stroke with HR reaching a maximum of 1.41 (95% CI: 1.06–1.90) for more than one event in childhood and 1.49 (95% CI: 1.09–2.04) for more than one event in adulthood. MLE accumulated over a life course showed a dose–response relationship with stroke. Associations were somewhat attenuated by adjustment for vital exhaustion suggesting a mediating role, but not by adjustment for behavioural risk factors. There were no associations between MLE and MI. Conclusion In this population-based cohort study, we found that MLE conveyed a moderately increased risk of stroke partly mediated through vital exhaustion. We found no association between MLE and the risk of MI. PMID:20038841

  17. Greater Happiness for a Greater Number: Did the Promise of Enlightenment Come True?

    In the eighteenth century 'Enlightened' thinkers challenged the belief that happiness exists only in Heaven. They claimed that happiness is possible in earthly life and foresaw that greater happiness would be achieved using reason. Did this promise of greater happiness come true? Several scholars doubt that we have become any happier and some claim that happiness has declined. These critical claims are tested using the time trend data available in the World Database of Happiness, which cover the period 1950-2010 and involve 1531 data points in 67 nations yielding 199 time-series ranging for 10 to more than 40 years. The analysis reveals that happiness has risen in most nations. The average yearly rise in the 67 nations was +0.012 on scale 0-10, which equals a rise of one full point every 83 years. At this rate happiness must have improved by more than two points over the past two centuries and, together with increasing longevity, this denotes an unprecedented rise in happy life years.

  20. Debris Flows Within The Greater Caucasus Northern Slope

    NASA Astrophysics Data System (ADS)

    Panova, S.

    Debris flows are recorded everywhere within the Greater Caucasus northern slope. In last decades studies of debris flows appeared to be very important due to an intensive anthropogenic activity in the mountainous areas. Debris flow spatial distribution, as well as their genesis and means of protection are critical, too. The studied terri- tory has significant absolute altitudes, especially in the central and eastern parts. Also large amount of atmospheric precipitation with maximum in a warm period is typical for the region. Modern glaciation with soil-covered moraine deposits of modern and Holocene age is developed in the region. Geological and geomorphological conditions lead to debris flows formation within the entire territory. However, the amount of atmospheric precipitation drastically decreases from west to east and in the eastern part (Dagestan) debris flow is less active than in the central even under the presence of enormous amounts of loose detrital material of different genesis. In the western part debris flows are less developed due to insignificant altitudes and considerable forest coverage and soil-cover. Powerful modern glaciation with vast development of purely moraine and fluvial-glacial deposits results in intensive debris flow activity in the central part of the northern slope (the Terek river basin). In the upper reaches of all the Terek tributaries moraine deposits reach up to several dozen meters. They are widespread at altitudes higher than 2000 m (above the forest boundary) and almost everywhere uncovered by soils. They are a key source of sediments under debris flow formation. Within the Greater Caucasus northern slope there are 1700 debris flow basins with the total area about 7000 km2. Their average area is 4.0 km2 with minimum 0.20 km2 and maximum 173.8 km2. Moreover, there are many riverbeds in the area where form mountain mud floods more than 3000 km long. Debris flows occur between January and October with clear altitudinal zoning

    This paper presents a detailed emission inventory for NOx, particle mass (PM) and particle numbers (PN) for aircraft main engines, APU's and handling equipment at Copenhagen Airport (CPH) based on time specific activity data and representative emission factors for the airport. The inventory has a high spatial resolution of 5 m × 5 m in order to be suited for further air quality dispersion calculations. Results are shown for the entire airport and for a section of the airport apron area ("inner apron") in focus. The methodology presented in this paper can be used to quantify the emissions from aircraft main engines, APU and handling equipment in other airports. For the entire airport, aircraft main engines is the largest source of fuel consumption (93%), NOx, (87%), PM (61%) and PN (95%). The calculated fuel consumption [NOx, PM, PN] shares for APU's and handling equipment are 5% [4%, 8%, 5%] and 2% [9%, 31%, 0%], respectively. At the inner apron area for handling equipment the share of fuel consumption [NOx, PM, PN] are 24% [63%, 75%, 2%], whereas APU and main engines shares are 43% [25%, 19%, 54%], and 33% [11%, 6%, 43%], respectively. The inner apron NOx and PM emission levels are high for handling equipment due to high emission factors for the diesel fuelled handling equipment and small for aircraft main engines due to small idle-power emission factors. Handling equipment is however a small PN source due to the low number based emission factors. Jet fuel sulphur-PM sensitivity calculations made in this study with the ICAO FOA3.0 method suggest that more than half of the PM emissions from aircraft main engines at CPH originate from the sulphur content of the fuel used at the airport. Aircraft main engine PN emissions are very sensitive to the underlying assumptions. Replacing this study's literature based average emission factors with "high" and "low" emission factors from the literature, the aircraft main engine PN emissions were estimated to change with a

    SummaryStormwater infiltration measures such as soakaways are expected to be part of future urban drainage systems. However, few studies exist on the effect of extensive stormwater infiltration through soakaways on the overall urban water system, including sewers and groundwater, at city catchment scale. In particular such estimates have not been made in real urban settings with multiple physical and structural constraints. This paper presents a methodology for conducting such an analysis, and provides quantitative estimates of the effects on the urban water flows. Using an interdisciplinary, three-step approach that employed GIS analyses and physically distributed, dynamic pipe flow modelling in an iterative manner, this study estimates the impact of infiltration on combined sewage overflows (CSOs) in a 3 km2 urban catchment in Copenhagen. The first step was the creation of a baseline scenario. The second step led to a potential infiltration scenario where 65% of the total impervious area was connected to soakaways, and resulted in an estimated reduction in annual sewage overflow volume of 68%. This scenario was then further developed in the third step by adding groundwater constraints, which formed a more realistic scenario where only 8% of the impervious area was connected to soakaways and the reduction in CSO volume was 24%. The potential and realistic scenarios were modelled both with hydraulic coupling between soakaway and sewer, and as fully disconnected. Results show that infiltration is constrained mainly by the quality of the stormwater runoff from roads and limited land availability in the potential infiltration scenario, and by low-permeable soils and a problematically high groundwater level in the realistic infiltration scenario. The hydraulically coupled model gives higher CSO volume than the fully disconnected model for the potential infiltration scenario, whereas no difference is seen between these two models in the realistic infiltration scenario

    Patient satisfaction is increasingly being tied to reimbursement rates, and patient satisfaction is often associated with improving functionality and decreasing disability postoperatively. This study sought to determine if a total shoulder arthroplasty patient's preoperative confidence in his or her ability to attain the level of activity desired would influence postoperative functional scores. Patients undergoing a primary total shoulder arthroplasty at a single institution were asked to complete a preoperative questionnaire with multiple items including baseline symptom severity measures and their confidence in reaching their level of desired functionality postoperatively (scored 0-10). Patients then completed an identical postoperative questionnaire at their follow-up visits. Associations between the patient's confidence in attaining treatment goals and functional outcomes was established by multiple linear regression models that were adjusted for gender, age, body mass index, baseline 12-Item Short Form Health Survey mental component scores, college education, smoking status, baseline functional scores, and length of follow-up. Patients had a high level of confidence that their outcome would match their expectations, with an average score of 7.8 (range, 0-10; 28.4% reported a full 10/10 confidence). For every 1-point increase in confidence, patients experienced an average increase in their function score of 2.7 points (P = .039) and improvement in their pain score of 2.0 (P = .033) according to the Penn Shoulder Score. There was no significant association with the patient's 12-Item Short Form Health Survey score postoperatively. Patients with greater preoperative confidence actually have significantly better postoperative functional outcomes than their less confident peers even with adjustment for other known risk factors.

    At 4,200 km, the Mekong River is the tenth longest river in the world. It directly and indirectly influences the lives of hundreds of millions of inhabitants in its basin. The riparian countries - Thailand, Myanmar, Cambodia, Laos, Vietnam, and a small part of China - form the Greater Mekong Subregion (GMS). This geographical region has the misfortune of being the world's epicenter of falciparum malaria, which is the most severe form of malaria caused by Plasmodium falciparum. Depending on the country, approximately 50 to 90% of all malaria cases are due to this species. In the Malaria Modeling and Surveillance Project, we have been developing techniques to enhance public health's decision capability for malaria risk assessments and controls. The main objectives are: 1) Identifying the potential breeding sites for major vector species; 2) Implementing a malaria transmission model to identify the key factors that sustain or intensify malaria transmission; and 3) Implementing a risk algorithm to predict the occurrence of malaria and its transmission intensity. The potential benefits are: 1) Increased warning time for public health organizations to respond to malaria outbreaks; 2) Optimized utilization of pesticide and chemoprophylaxis; 3) Reduced likelihood of pesticide and drug resistance; and 4) Reduced damage to environment. Environmental parameters important to malaria transmission include temperature, relative humidity, precipitation, and vegetation conditions. These parameters are extracted from NASA Earth science data sets. Hindcastings based on these environmental parameters have shown good agreement to epidemiological records.

    Domestic violence (DV) is a major public health problem with high health and social costs. A solution to this multi-faceted problem requires that various help providers work together in an effective and optimal manner when dealing with different parties of DV. The objective of our research and development project (2008-2013) was to improve the preparedness of the social and healthcare professionals to manage DV. This article focuses on the evaluation of interprofessional education (IPE) to provide knowledge and skills for identifying and intervening in DV and to improve collaboration among social and health care professionals and other help providers at the local and regional level. The evaluation data were carried out with an internal evaluation. The evaluation data were collected from the participants orally and in the written form. The participants were satisfied with the content of the IPE programme itself and the teaching methods used. Participation in the training sessions could have been more active. Moreover, some of the people who had enrolled for the trainings could not attend all of them. IPE is a valuable way to develop intervening in DV. However, greater commitment to the training is required from not only the participants and their superiors but also from trustees.

    As earth scientists, we are drawn together by our fascination with the natural world. On alpine climbing expeditions in the Greater Ranges of Asia during 2012-14, I had the opportunity to contribute to the scientific understanding and stewardship of the places I visit for personal fulfillment. Using the "matchmaking" services of Adventurers and Scientists for Conservation, I was connected with researchers to conduct field studies in some of the world's highest and most remote mountains. Here, I present work from two projects: 1) Assessing the role of biological weathering in shaping high altitude landscapes in the Pamir Mountains of Kyrgyzstan and Tajikistan, and 2) Understanding the effects of anthropogenic biomass burning on glacial thinning in the Everest Region, Nepal. Both collaborative efforts succeeded in collecting valuable data from challenging environments using a small research budget. As a scientist with expertise in terrestrial paleoclimate and stable isotope geochemistry, these projects served to expand my research horizons and areas of professional interest. Citizen science can not only add a sense of value to otherwise selfish endeavors such as high altitude climbing, but also serve to connect scientists with the communities who appreciate their efforts most.

    Greater Sage-Grouse (Centrocercus urophasianus) have been declining in many states and provinces of North America, and North and South Dakota hold no exception to these declines. We studied effects of cultivated land on Greater Sage-Grouse lek abandonment in North and South Dakota. Landscape-level data were assessed using satellite imagery within a geographic information system. Comparisons were made of 1972-1976 and 1999-2000 percent cultivated and noncultivated land. These comparisons were made between land uses surrounding active leks versus inactive leks, active leks versus random locations, and abandoned regions versus active regions. The 1999-2000 imagery illustrated that percent cultivated land was greater near abandoned leks (4-km buffers) than near active leks in North Dakota or random sites, but this did not hold true in South Dakota. Comparison of an extensive region of abandoned leks with a region of active leks in North Dakota illustrated a similar increase as well as dispersion of cultivation within the abandoned region. However, 1972-1976 imagery revealed that this relationship between percentage of cultivated land and lek activity in North Dakota has been static over the last 30 years. Thus, if the decline of Greater Sage-Grouse is the result of cultivated land infringements, it occurred prior to 1972 in North Dakota.

    The Greater Mekong Subregion (GMS), comprised of six countries including Cambodia, China's Yunnan Province, Lao PDR, Myanmar (Burma), Thailand and Vietnam, is one of the most threatening foci of malaria. Since the initiation of the WHO's Mekong Malaria Program a decade ago, malaria situation in the GMS has greatly improved, reflected in the continuous decline in annual malaria incidence and deaths. However, as many nations are moving towards malaria elimination, the GMS nations still face great challenges. Malaria epidemiology in this region exhibits enormous geographical heterogeneity with Myanmar and Cambodia remaining high-burden countries. Within each country, malaria distribution is also patchy, exemplified by ‘border malaria’ and ‘forest malaria’ with high transmission occurring along international borders and in forests or forest fringes, respectively. ‘Border malaria’ is extremely difficult to monitor, and frequent malaria introductions by migratory human populations constitute a major threat to neighboring, malaria-eliminating countries. Therefore, coordination between neighboring countries is essential for malaria elimination from the entire region. In addition to these operational difficulties, malaria control in the GMS also encounters several technological challenges. Contemporary malaria control measures rely heavily on effective chemotherapy and insecticide control of vector mosquitoes. However, the spread of multidrug resistance and potential emergence of artemisinin resistance in Plasmodium falciparum make resistance management a high priority in the GMS. This situation is further worsened by the circulation of counterfeit and substandard artemisinin-related drugs. In most endemic areas of the GMS, P. falciparum and P. vivax coexist, and in recent malaria control history, P. vivax has demonstrated remarkable resilience to control measures. Deployment of the only registered drug (primaquine) for the radical cure of vivax malaria is

  13. Deviance and resistance: Malaria elimination in the greater Mekong subregion.

    Malaria elimination rather than control is increasingly globally endorsed, requiring new approaches wherein success is not measured by timely treatment of presenting cases but eradicating all presence of infection. This shift has gained urgency as resistance to artemisinin-combination therapies spreads in the Greater Mekong Sub-region (GMS) posing a threat to global health security. In the GMS, endemic malaria persists in forested border areas and elimination will require calibrated approaches to remove remaining pockets of residual infection. A new public health strategy called 'positive deviance' is being used to improve health promotion and community outreach in some of these zones. However, outbreaks sparked by alternative understandings of appropriate behaviour expose the unpredictable nature of 'border malaria' and difficulties eradication faces. Using a recent spike in infections allegedly linked to luxury timber trade in Thai borderlands, this article suggests that opportunities for market engagement can cause people to see 'deviance' as a means to material advancement in ways that increase disease vulnerability. A malaria outbreak in Ubon Ratchathani was investigated during two-week field-visit in November 2014 as part of longer project researching border malaria in Thai provinces. Qualitative data were collected in four villages in Ubon's three most-affected districts. Discussions with villagers focused primarily on changing livelihoods, experience with malaria, and rosewood cutting. Informants included ten men and two women who had recently overnighted in the nearby forest. Data from health officials and villagers are used to frame Ubon's rise in malaria transmission within moral and behavioural responses to expanding commodity supply-chains. The article argues that elimination strategies in the GMS must contend with volatile outbreaks among border populations wherein 'infectiousness' and 'resistance' are not simply pathogen characteristics but also

    Grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE) are opportunistic omnivores that eat a great diversity of plant and animal species. Changes in climate may affect regional vegetation, hydrology, insects, and fire regimes, likely influencing the abundance, range, and elevational distribution of the plants and animals consumed by GYE grizzly bears. Determining the dietary breadth of grizzly bears is important to document future changes in food resources and how those changes may affect the nutritional ecology of grizzlies. However, no synthesis exists of all foods consumed by grizzly bears in the GYE. We conducted a review of available literature and compiled a list of species consumed by grizzly bears in the GYE. We documented >266 species within 200 genera from 4 kingdoms, including 175 plant, 37 invertebrate, 34 mammal, 7 fungi, 7 bird, 4 fish, 1 amphibian, and 1 algae species as well as 1 soil type consumed by grizzly bears. The average energy values of the ungulates (6.8 kcal/g), trout (Oncorhynchus spp., 6.1 kcal/g), and small mammals (4.5 kcal/g) eaten by grizzlies were higher than those of the plants (3.0 kcal/g) and invertebrates (2.7 kcal/g) they consumed. The most frequently detected diet items were graminoids, ants (Formicidae), whitebark pine seeds (Pinus albicaulis), clover (Trifolium spp.), and dandelion (Taraxacum spp.). The most consistently used foods on a temporal basis were graminoids, ants, whitebark pine seeds, clover, elk (Cervus elaphus), thistle (Cirsium spp.), and horsetail (Equisetum spp.). Historically, garbage was a significant diet item for grizzlies until refuse dumps were closed. Use of forbs increased after garbage was no longer readily available. The list of foods we compiled will help managers of grizzly bears and their habitat document future changes in grizzly bear food habits and how bears respond to changing food resources.

    This study addresses the recent climatology of hail occurrence in the Greater Metropolitan Severe Thunderstorm Warning Area (GMSTWA) of New South Wales (NSW). The study area is a sprawling suburban area with a population of nearly 4.7 million and one of Australia's largest metropoles. The main objective is to highlight the recent temporal-spatial fluctuations of hail event frequencies and magnitudes (sizes) for each of recognized and vastly inhabited local government areas (LGAs). The relevant hail event data from 1989 to 2013 were initially derived from the severe storm archive of the Australian Bureau of Meteorology. A climatologically oriented GIS technique was then applied in the examining and mapping procedure of all hail events and hail days reported throughout the study area. By applying a specific criterion, severe hail (defined as 2 cm or more in diameter) was cautiously selected for relevant analysis. The database includes 357 hail events with sizes 2-11 cm which occurred in 169 hail days (a day in which a hail event at least more than 2 cm reported) across the region during the past 25 years. The hail distribution patterns are neither temporally nor spatially uniform in magnitude throughout the study area. Temporal analysis indicated that most of hail events occur predominately in the afternoons with peak time of 1-5 p.m. Australian eastern standard time (EST). They are particularly common in spring and summer, reaching maximum frequency in November and December. There is an average of 14.3 events per year, but a significant decreasing trend in hail frequency and associated magnitude in the recent years has been identified. In turn, spatial analyses also established three main distribution patterns over the study area which include the Sydney metropolitan, the coastal and the most pronounced topographic effects. Based on the understanding of the favorable factors for thunderstorm development in the GMSTWA, the potential impacts from climate variability

    The Greater Mekong Subregion (GMS) has low transmission of Plasmodium falciparum and P. vivax and is a prime region for malaria elimination based on evidence. The extent of GMS based research is unknown. Pub Med-identified research articles from the GMS were selected based on defined criteria and classified into 24 research areas. A research questionnaire was sent to WHO country offices, national malaria control programs (NMCPs), national research institutes and non governmental organizations (NGOs). Two thousand eight hundred ninety of 3,319 identified publications were included, dating from 1933 to June 2012; 1,485 (51.8%) of 2,890 since 2000. Ten research areas accounted for 2,264 (78.3%) publications: drug resistance 12.8% (n=371), entomology 11.42% (n=330), clinical trials 10.45% (n=302), pathophysiology 9.34% (n=270), epidemiology 8.96% (n=259), pharmacology 6.06% (n=175), parasite biology 5.19% (n=150), malaria control 4.88% (n=141), diagnosis/diagnostics 4.6% (n=133) and clinical studies 4.6% (n=133). Thailand produced most publications, 1,684 (58.27%), followed by Viet Nam (365, 12.63%), Cambodia (139, 4.81%), Myanmar (132, 4.57%), Yunnan Province, China (124, 4.3%) and Lao PDR (79, 2.73%). Other publications were multicountry, including >or=1 GMS country (n=269), or reviews (n=98). Publication numbers increased significantly over time. Eleven questionnaires were received. Principal research areas were treatment seeking behavior, knowledge, attitude and practice surveys, bed net use, access to treatment by migrants, and malaria diagnostics. Research in GMS is broad. Biomedical research dominates peer reviewed publications. NMCP and NGOs focus more on downstream malaria implementation issues. The challenge is to engage GMS research capacity to build quality evidence for malaria elimination.

    The Greater Caribbean biogeographic region is the high-diversity heart of the Tropical West Atlantic, one of four global centers of tropical marine biodiversity. The traditional view of the Greater Caribbean is that it is limited to the Caribbean, West Indies, southwest Gulf of Mexico and tip of Florida, and that, due to its faunal homogeneity, lacks major provincial subdivisions. In this scenario the northern 2/3 of the Gulf of Mexico and southeastern USA represent a separate temperate, "Carolinian" biogeographic region. We completed a comprehensive re-assessment of the biogeography of the Greater Caribbean by comparing the distributions of 1,559 shorefish species within 45 sections of shelf waters of the Greater Caribbean and adjacent areas. This analysis shows that that the Greater Caribbean occupies a much larger area than usually thought, extending south to at least Guyana, and north to encompass the entire Carolinian area. Rather than being homogenous, the Greater Caribbean is divided into three major provinces, each with a distinctive, primarily tropical fauna: (1) a central, tropical province comprising the West Indies, Bermuda and Central America; (2) a southern, upwelling-affected province spanning the entire continental shelf of northern South America; and (iii) a northern, subtropical province that includes all of the Gulf of Mexico, Florida and southeastern USA. This three-province pattern holds for both reef- and soft bottom fishes, indicating a general response by demersal fishes to major variation in provincial shelf environments. Such environmental differences include latitudinal variation in sea temperature, availability of major habitats (coral reefs, soft bottom shorelines, and mangroves), and nutrient additions from upwelling areas and large rivers. The three-province arrangement of the Greater Caribbean broadly resembles and has a similar environmental basis to the provincial arrangement of its sister biogeographic region, the Tropical Eastern

  18. Late Paleozoic deformation of interior North America: The greater Ancestral Rocky Mountains

    SciTech Connect

    Ye, Hongzhuan |; Royden, L.; Burchfiel, C.; Schuepbach, M.

    1996-09-01

    Late Paleozoic deformation within interior North America has produced a series of north-northwest- to northwest-trending elongate basins that cover much of Oklahoma, Texas, New Mexico, Colorado, and Utah. Each basin thickens asymmetrically toward an adjacent region of coeval basement uplift from which it is separated by synsedimentary faults with great vertical relief. The remarkable coincidence in timing, geometry, and apparent structural style throughout the region of late Paleozoic deformation strongly suggests that these paired regions of basin subsidence and basement uplift form a unified system of regional deformation, the greater Ancestral Rocky Mountains. Over this region, basin subsidence and basement uplift were approximately synchronous, beginning in the Chesterian-Morrowan, continuing through the Pennsylvanian, and ending in the Wolfcampian (although minor post-Wolfcampian deformation occurs locally). The basement uplifts show evidence for folding and faulting in the Pennsylvanian and Early Permian. Reverse faults and thrust faults have been drilled over many of the uplifts, but only in the Anadarko region has thrusting of the basement uplifts over the adjacent basin been clearly documented. Extensive basement-involved thrusting also occurs along the margins of the Delaware and Midland basins, and suggests that the entire greater Ancestral Rocky Mountains region probably formed as the result of northeast-southwest-directed-intraplate shortening. Deformation within the greater Ancestral Rocky Mountains was coeval with late Paleozoic subduction along much of the North American plate margin, and has traditionally been related to emplacement of thrust sheets within the Ouachita-Marathon orogenic belt. The nature, timing, and orientation of events along the Ouachita-Marathon belt make it difficult to drive the deformation of the greater Ancestral Rocky Mountains by emplacement of the Ouachita-Marathon belt along the southern margin of North America.

    Investigate whether high physical work demands increase risk of ischemic heart disease (IHD) mortality among men of low social class with low physical fitness. Thirty-year follow-up in the Copenhagen Male Study of 5249 men aged 40 to 59 years without cardiovascular disease. Physical fitness was estimated using the Åstrand cycling test, and physical work demands determined by two self-reported questions. Among 2707 low social class men, multiple-adjusted Cox proportional hazard ratios showed an almost threefold increased risk of IHD mortality among men with high physical work demands and low physical fitness, but not among men with a high physical fitness, referencing men with low physical work demands. These findings among low social class men support that high physical work demands increases the risk of IHD mortality among those with low physical fitness.

    From November 1951 to December 1957, 666 consecutive patients with untreated primary breast cancer admitted to the Radium Center in Copenhagen were randomised before their operability was evaluated into two groups, simple mastectomy with postoperative radiotherapy or extended radical mastectomy. Following physical examination 241 of the patients were excluded, primarily due to tumours deemed inoperable due to clinical criteria (n =107) and due to poor general condition (n =69). Twenty-five years results of disease-free free survival and fifty years results of survival are presented, showing no difference between the two groups. Patients with clinical stage I did significantly better than patients with stage II-III tumours. Patients with grade I tumours had a better survival than patients with grade II-III. The breast cancer associated mortality was lower in premenopausal patients compared to postmenopausal patients. An excess mortality due to breast cancer was evident up to 20-25 years following the primary diagnosis.

    Objectives Men with low physical fitness and high occupational physical activity are recently shown to have an increased risk of cardiovascular disease and all-cause mortality. The association between occupational physical activity with cardiovascular disease and all-cause mortality may also depend on leisure time physical activity. Design A prospective cohort study. Setting The Copenhagen City Heart Study. Participants 7819 men and women aged 25–66 years without a history of cardiovascular disease who attended an initial examination in the Copenhagen City Heart Study in 1976–1978. Outcome measures Myocardial infarction and all-cause mortality. Occupational physical activity was defined by combining information from baseline (1976–1978) with reassessment in 1981–1983. Conventional risk factors were controlled for in Cox analyses. Results During the follow-up from 1976 to 1978 until 2010, 2888 subjects died of all-cause mortality and 787 had a first event of myocardial infarction. Overall, occupational physical activity predicted all-cause mortality and myocardial infarction in men but not in women (test for interaction p=0.02). High occupational physical activity was associated with an increased risk of all-cause mortality among men with low (HR 1.56; 95% CI 1.11 to 2.18) and moderate (HR 1.31; 95% CI 1.05 to 1.63) leisure time physical activity but not among men with high leisure time physical activity (HR 1.00; 95% CI 0.78 to 1.26) (test for interaction p=0.04). Similar but weaker tendencies were found for myocardial infarction. Among women, occupational physical activity was not associated with subsequent all-cause mortality or myocardial infarction. Conclusions The findings suggest that high occupational physical activity imposes harmful effects particularly among men with low levels of leisure time physical activity. PMID:22331387

    We report on two cases of acute liver injury along with the intake of Greater Celandine (Chelidonium majus), a well-known herbal remedy frequently used for irritable bowel syndrome. All other possible causes of acute liver damage were excluded in both patients. In one patient, cholestatic hepatitis recurred rapidly after involuntary re-exposition. Both patients fully recovered after the withdrawal of Greater Celandine. The two cases add to the existing database about the potential hepatotoxicity of drugs containing Greater Celandine and raise the question whether the approval of this drug should be re-evaluated in the light of lacking evidence for a therapeutic benefit.

  4. Does bone density of the greater tuberosity change in patients over 70?

    2014-02-01

    There are no published studies on bone density of the greater tuberosity of the humerus, which could influence the stability of reinsertion by suture anchors. The goal of our study was to determine the influence of age, gender and the type of tear on the quality of bone in the greater tuberosity. Ninety-eight patients over the age of 60 were included, 41 without a rotator cuff tear and 57 with an isolated stage 1 or 2 supraspinatus tear and fatty infiltration (FI) ≤ 2. The areas of measurement included cancellous bone located under the cortex of the greater tuberosity. Measurements were obtained either across from the tear or from the middle facet with greater tuberosity if the cuff was not torn. We measured average, maximum and minimum bone density and the standard deviation (SD) in each region with Osirix software. The two groups were similar for age (73), investigated side and mean densities (0.282 g/cm(2) vs 0.210 g/cm(2)). Age over 70 was a predictive factor for osteoporosis of the greater tuberosity whether or not a rotator cuff tear was present (P<0.0001). There was less trabecular bone in women with cuff tears (P=0.009). Stage 2 cuff retraction was predictive of osteoporosis of the greater tuberosity (P=0.0001). This is the first study in the literature to evaluate bone density of the greater tuberosity in relation to the presence or not of a rotator cuff tear in an elderly population. Female gender, age over 70 and stage 2 cuff retraction are factors responsible for osteoporosis of the greater tuberosity of the humeral head. The osteoporosis is not severe, and normally the quality of bone of the greater tuberosity should not limit stability of suture anchors. 3. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

  5. A new probabilistic seismic hazard assessment for greater Tokyo

    2006-12-01

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105,000 lives. Unlike California's seismic environment of shallow and largely strike-slip faults, Tokyo lies 200 km from a triple junction with two subduction zones, and 80 km from a front of active volcanoes. Further, some of the region's megathust faults are seismically coupled, some undergo episodic slip events, and others appear to be permanently aseismic. To reinterpret the tectonic structure, identify active faults and their slip rates, and estimate their earthquake frequency, we analyzed the 7,000-yr record of seventeen M~8 shocks preserved by uplifted marine terraces and tsunami deposits, and 150 GPS vectors in the past 10 years from Japan's GeoNet array. We also digitized 10,000 observations of historical shaking recorded over the past 400 years, and examined 300,000 earthquakes registered by the dense NIED/JMA network in a 3D geographic information system. In a principal departure from previous work, we propose that a 100-km-wide, 25-km-thick dislodged fragment of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath Tokyo, and argue that the this fragment controls much of Tokyo's seismic behavior, including the damaging 1855 M~7.1 Ansei-Edo shock. On the basis of the frequency of earthquakes beneath greater Tokyo, we estimate that events with magnitude and location similar to the Ansei-Edo event have a 20% likelihood in an average 30-yr period. In contrast, our renewal (time-dependent) probability for great M~7.9 megathrust shocks such as struck in 1923 and 1703 is just 0.5% for the next 30 years, with a time-averaged 30-yr probability of ~10%. The resulting net likelihood for severe shaking (~0.9 g peak ground acceleration) in Tokyo, Kawasaki, and Yokohama for the next 30 years is ~30%, and the annual probability is 1.3%.

    Little information is available about diseases and pathology of species within the family Tenrecidae, including the greater hedgehog tenrec (Setifer setosus), a Madagascan insectivore. This report summarizes necropsy and histopathologic findings of neoplasia in four captive greater hedgehog tenrecs. Although only four animals are included in this report, neoplasia seems to be a common and significant source of morbidity and mortality in greater hedgehog tenrecs. Types of neoplasia identified include a thyroid follicular-solid carcinoma, two urinary bladder transitional cell carcinomas, uterine endometrial polyps, and multicentric B-cell lymphoma. Due to small sample size, no etiology could be determined, but genetics, viral infection, pesticide treatment, nutrition, or other environmental factors might contribute to the development of neoplasia in this species. This is the first report of neoplasia in greater hedgehog tenrecs.

    The GREAT-ER (Geo-referenced Regional Exposure Assessment Tool for European Rivers) project team has developed and validated an accurate aquatic chemical exposure prediction tool for use within environmental risk assessment schemes. The software system GREAT-ER 1.0 calculates the distribution of predicted environmental concentrations (PECs) of consumer chemicals in surface waters, for individual river stretches as well as for entire catchments. The system uses an ARC/INFO-ArcView (ESRI) based Geographical Information System (GIS) for data storage and visualization, combined with simple mathematical models for prediction of chemical fate. At present, the system contains information for four catchments in Yorkshire, one catchment in Italy, and two in Germany, while other river basins are being added. Great-ER 1.0 has been validated by comparing simulations with the results of an extensive monitoring campaign for two 'down-the-drain' chemicals, i.e. the detergent ingredients boron and Linear Alkylbenzene Sulphonate (LAS). GREAT-ER 1.0 is currently being expanded with models for the terrestrial (diffuse input), air and estaurine compartments.

  10. Greater striatal dopamine transporter density may be associated with major depressive episode.

    PubMed

    Amsterdam, Jay D; Newberg, Andrew B; Soeller, Irene; Shults, Justine

    2012-12-10

    We examined striatal dopamine transporter (DAT) distribution volume ratio (DVR) values in subjects with unipolar or bipolar major depressive episode (versus non-depressed healthy volunteers) using the selective DAT radioligand [(99m)Tc]TRODAT-1 and single photon emission computed tomography (SPECT). We hypothesized that striatal DVR values would be greater in depressed versus non-depressed subjects, and that greater DVR values may represent a possible clinical biomarker of depression. [(99m)Tc]TRODAT-1 spect images were acquired from 39 depressed and 103 non-depressed drug-free subjects. The primary outcome measure was the DVR value of [(99m)Tc]TRODAT-1 binding for the putamen region and the combined putamen plus caudate region. DVR values were significantly correlated across all striatal regions within both subject groups (p<0.005). Depressed subjects had significantly greater DVR values (versus non-depressed subjects) in the putamen (p<0.0005) and the combined putamen plus caudate (p<0.0005) regions. There was no difference in DVR values between unipolar (n=24) and bipolar (n=15) depressed subjects, and no difference in DVR values for depressed subjects with or without prior antidepressant exposure. The predictive probability of the putamen or combined putamen plus caudate DVR value to distinguish depressed from non-depressed subjects was significant (p<0.0005). DAT values could potentially be influenced by age, gender, diagnosis, prior psychotropic dug exposure, illness length, or symptom severity. Results confirm prior observations of greater striatal DAT density in depressed versus non-depressed subjects, and suggest that greater DVR values may possibly represent a potential diagnostic biomarker for distinguish depressed from non-depressed individuals.

  11. ICAO safety management systems (SMS) development in environmental contexts: A field study of greater China

    NASA Astrophysics Data System (ADS)

    Leib, Steven M.

    This was a mixed-methods exploratory study to investigate association between environmental context and the implementation status of Safety Management Systems (SMS) at airports in Greater China. Using a framework of Institutional Theory, this study looked at three regions of Greater China and explored internal and external environments of SMS at airports within each region. It used ICAO standards to evaluate the implementation status of SMS at those airports based on the perceptions of 126 participants. This research also employed snowballing technique to spread a survey tool to participants in Greater China through several key gatekeepers, and then applied the Delphi method for interviews with key gatekeepers themselves. Analysis of the data suggested several associations between various sub-concepts of the external environment and different components of SMS in the three regions. In addition, the data suggested a relationship between the internal environment as a whole and the overall status of SMS implementation in each region. Lastly, the study makes several recommendations for future research regarding global standards implemented in local environments, the evaluation of SMS implementation status, and the theoretical implications of this study.

  12. Improving greater trochanteric reattachment with a novel cable plate system.

    2013-03-01

    Cable-grip systems are commonly used for greater trochanteric reattachment because they have provided the best fixation performance to date, even though they have a rather high complication rate. A novel reattachment system is proposed with the aim of improving fixation stability. It consists of a Y-shaped fixation plate combined with locking screws and superelastic cables to reduce cable loosening and limit greater trochanter movement. The novel system is compared with a commercially available reattachment system in terms of greater trochanter movement and cable tensions under different greater trochanteric abductor application angles. A factorial design of experiments was used including four independent variables: plate system, cable type, abductor application angle, and femur model. The test procedure included 50 cycles of simultaneous application of an abductor force on the greater trochanter and a hip force on the femoral head. The novel plate reduces the movements of a greater trochanter fragment within a single loading cycle up to 26%. Permanent degradation of the fixation (accumulated movement based on 50-cycle testing) is reduced up to 46%. The use of superelastic cables reduces tension loosening up to 24%. However this last improvement did not result in a significant reduction of the grater trochanter movement. The novel plate and cables present advantages over the commercially available greater trochanter reattachment system. The plate reduces movements generated by the hip abductor. The superelastic cables reduce cable loosening during cycling. Both of these positive effects could decrease the risks related to grater trochanter non-union. Copyright © 2012 IPEM.

  13. Non-greater saphenous vein grafting for infrageniculate bypass.

    PubMed

    Alexander, Jason; Gutierrez, Charles; Katz, Steven

    2002-07-01

    Infrainguinal bypass grafting with greater saphenous vein has proven to be a highly effective procedure with primary 5-year patency and limb salvage rates exceeding 80 per cent. However, because of prior usage or intrinsic venous disease the greater saphenous vein is often not available as a conduit. Numerous studies have shown that patency rates for prosthetic bypass grafting to the infrageniculate vessels are clearly inferior to that reported for greater saphenous vein bypass. In this report we summarize our experience with the use of alternate autogenous vein grafting to the infrageniculate vessels. The records of all patients undergoing autogenous bypass grafting to the infrageniculate vessels using a conduit other than the greater saphenous vein between 1992 and 1999 were reviewed. Graft survival curves were plotted using the Kaplan-Meier method and results are reported using the Society for Vascular Surgery/International Society for Cardiovascular Surgery guidelines. Forty-eight patients underwent a total of 51 infrageniculate bypass procedures using non-greater saphenous autogenous conduits. Thirty-nine patients had reconstructions performed with single segments of arm vein, two had their operations performed with lesser saphenous vein, and ten had grafts created with two segments of non-greater saphenous autogenous vein. Twenty-one grafts were performed to the infrageniculate popliteal artery and 30 were performed to the tibial vessels. Primary and primary assisted patency rates at 30 months were 49 and 75 per cent. Limb salvage was 87 per cent. Infrainguinal bypass grafting using non-greater saphenous autogenous conduits can yield quite satisfactory intermediate limb salvage and patency rates. However, close graft surveillance and prompt intervention are required to avoid graft failure.

We present the results of mouse bioassay studies to show that, contrary to findings in cattle with BSE in which the tissue distribution of infectivity is the most limited recorded for any of the transmissible spongiform encephalopathies (TSE), infectivity in greater kudu with BSE is distributed in as wide a range of tissues as occurs in any TSE. BSE agent was also detected in skin, conjunctiva, and salivary gland, tissues in which infectivity has not previously been reported in any naturally occurring TSE. The distribution of infectivity in greater kudu with BSE suggests possible routes for transmission of the disease and highlights the need for further research into the distribution of TSE infectious agents in other host species.

    Isolated greater trochanter fractures after total hip arthroplasty are associated with major comorbidities such as debilitating weakness, pain, and dislocation. No definitive standard of care has been established for these fracture. However, it is well known that reestablishing osseous union in these patients is strongly associated with return of functional status. We report a case of an elderly patient with multiple hip revision surgeries now presenting with unilateral greater trochanter fracture. Treatment incorporated the use of a trochanteric claw plate, cerclage wiring, and adjuvant demineralized bone matrix allograft to achieve successful osseous union. This is the first reported use of adjuvant demineralized bone matrix for fixing these fractures.

    The Greater Shearwater (Puffinus gravis) breeds in the southern Atlantic Ocean and disperses after breeding to the North Atlantic. On 3 August 2001, I observed and photographed an unidentified shearwater (Figure 1) in the Gulf of Alaska, about 30 km off the southern coast of Montague Island (59°50' N, 148°00' W). The bird was subsequently identified as a Greater Shearwater. This observation and photographic documentation provides the first Alaska state record (D. Gibson in litt.) and one of very few records for the North Pacific (see Table 1). This is the 464th bird species to be recorded in the state of Alaska.

    As a part of the study of the vestibular-autonomic pathways involved in motion sickness, the location and the morphology of preganglionic sympathetic neurons (PSNs) projecting via the greater splanchnic nerve were examined. Retrograde labeling of neurons was obtained by application of horseradish peroxidase to the cut end of the greater splanchnic nerve. Labeled PSNs were found, ipsilaterally, within the T1 to T11 spinal cord segments, with the highest density of neurons in T6. Most PSNs were located within the intermediolateral column, but a significant portion also occurred within the lateral funiculus, the intercalated region, and the central autonomic area; the proportion of labeling between the four regions depended on the spinal cord segment.

    2011-01-01

    Background and purpose The diagnosis and treatment of isolated greater tuberosity fractures of the proximal humerus is not clear-cut. We retrospectively assessed the clinical and radiographic outcome of isolated greater tuberosity fractures. Patients and methods 30 patients (mean age 58 (26–85) years, 19 women) with 30 closed isolated greater tuberosity fractures were reassessed after an average follow-up time of 3 years with DASH score and Constant score. Radiographic outcome was assessed on standard plain radiographs. Results 14 of 17 patients with undisplaced or slightly displaced fractures (≤ 5 mm) were treated nonoperatively and had good clinical outcome (mean DASH score of 13, mean Constant score of 71). 8 patients with moderately displaced fractures (6–10 mm) were either treated nonoperatively (n = 4) or operatively (n = 4), with good functional results (mean DASH score of 10, mean Constant score of 72). 5 patients with major displaced fractures (> 10 mm) were all operated with good clinical results (mean DASH score of 14, mean Constant score of 69). The most common discomfort at the follow-up was an impingement syndrome of the shoulder, which occurred in both nonoperatively treated patients (n = 3) and operatively treated patients (n = 4). Only 1 nonoperatively treated patient developed a non-union. By radiography, all other fractures healed. Interpretation We found that minor to moderately displaced greater tuberosity fractures may be treated successfully without surgery. PMID:21895502

    The hepatotoxic potential of conventional drugs is well known, but herbal medicines are often assumed to be harmless. In the last 2 years, we have observed 10 cases of acute hepatitis induced by preparations of greater celandine (Chelidonium majus), which are frequently prescribed to treat gastric and biliary disorders. The course of hepatitis was mild to severe. Marked cholestasis was observed in 5 patients, but liver failure did not occur. Other possible causes of liver disease (viral, autoimmune, hereditary, alcohol, and secondary biliary) were excluded by laboratory tests and imaging procedures, and liver biopsy specimens were consistent with drug-induced damage. After discontinuation of greater celandine, rapid recovery was observed in all patients and liver enzyme levels returned to normal in 2-6 months. Unintentional rechallenge led to a second flare of hepatic inflammation in 1 patient. Greater celandine has to be added to the list of herbs capable of inducing acute (cholestatic) hepatitis. A significant proportion of unexplained cases of hepatitis may be caused by greater celandine.

  18. Advancing Research on Productive Aging Activities in Greater Chinese Societies.

    PubMed

    Lum, Terry Yat-Sang

    2013-06-01

    The public discourse on productive aging as a research and policy initiative has just begun in greater China. Two conferences in Mainland China in 2009 and 2011 and subsequent conferences in Taiwan and Hong Kong in 2012 have set it in motion. Because applied social science research has just started in greater China, researchers in Chinese societies will benefit from the experience and rich literature accumulated over the last three decades in the West. In this paper, I review and reflect on the research methods used in productive aging research in both Chinese societies and in the West. I believe that to advance productive aging research in greater China, we need to (1) discuss and agree upon a definition of productive aging, (2) identify and differentiate outputs and outcomes of productive aging activities in greater China, (3) develop precise measures for productive aging involvement, (4) focus on institutional (program and public policy) factors that promote productive aging involvement, (5) use a strong research design (such as a quasi-experimental design) to establish the internal validity of productive aging programs, and (6) be theory-driven. Lastly, productive aging should be seen as a choice, not an obligation for older people; otherwise, the productive aging agenda will be seen as exploiting older people. It is important that Chinese researchers and policy-makers have this in mind when they are advocating productive engagement of older people in China.

  19. Surgical treatment of high-standing greater trochanter.

    Takata, K; Maniwa, S; Ochi, M

    1999-01-01

    Eleven patients with high-standing greater trochanter (13 joints) aged 13-36 years underwent surgery. Distal transfer of the greater trochanter (group T) was performed in 4 patients (5 joints) and lateral displacement osteotomy (group L) in 7 (8 joints). The average follow-up duration was 13.4 years in group T and 5.9 years in group L. Clinical results were evaluated by the hip score according to Merle d'Aubigne. The mean hip score in group T was 13.4 points before operation and 15.4 points after operation, and in group L, 12.8 and 17.4 points, respectively. The postoperative clinical results of group L were significantly better than those of group T (P = 0.0494). In radiological evaluation, although the articulo-trochanteric distance (ATD) increased in both groups in group L it improved remarkably from 9.8 to 24.3, indicating a large descending distance of the greater trochanter. The lever arm ratio (LAR) did not change significantly in group T, but it decreased from 1.97 to 1.60 in group L (P = 0.004). This means that the lever arm of the abductors can certainly be extended by lateral displacement osteotomy. Lateral displacement osteotomy is the most effective procedure for high-standing greater trochanter.

  20. Arthroscopic treatment for greater tuberosity fractures: rationale and surgical technique.

    PubMed

    Taverna, Ettore; Sansone, Valerio; Battistella, Ferdinando

    2004-07-01

    A description of a new technique for arthroscopic treatment of minimally displaced greater tuberosity fractures of the humerus and associated soft tissue lesions is presented. This kind of fracture is usually treated nonsurgically. However, recent evidence suggests that even a small amount of superior displacement may produce shoulder dysfunction and require a perfect surgical reduction and fixation. Moreover, any displaced fracture of the greater tuberosity presents a high rate of associated and largely undetected soft tissue lesions. To avoid underestimating accompanying soft tissue pathology, arthroscopic assessment before open treatment of greater tuberosity fractures has been suggested. In 2 earlier case reports, we described the use of an arthroscope not only to diagnose and treat a rotator cuff tear and a Bankart lesion associated with a minimally displaced greater tuberosity fracture but also to arthroscopically reduce and treat the fracture. With advancements in arthroscopy and equipment, we refined and systematized the original arthroscopic technique that we have routinely used since 1997. This article presents the new technique.

  1. The Uplift of the Greater and Lesser Caucasus: Continental Collision to Subduction

    The Caucasus is a part of the orogenic belt which formed as the result of the closure of the Neo Tethys Ocean and the corresponding continental collision of Arabian and Eurasian plates. This region includes the southwestern part of the Caspian basin, the Kura basin, the Lesser and Greater Caucasus mountains, and the East Anatolian and North Iranian plateaus. A number of tomographic studies of both P and S wave velocities all show a broad low velocity zone beneath East Anatolian and North Iranian plateaus and most models show three high velocity zones located under the eastern part of the Greater Caucasus, the Talesh and Pontides. The low velocity zone is observed starting right at the moho down to 150 km, which suggests asthenospheric material underlying a very thin lithosphere of eastern Anatolia where widespread Late Miocene - Quaternary calc-alkaline volcanic products of mantle origin are reported. There appears to be a high velocity body beneath the eastern Greater Caucasus and Kura Basin at depths below the Moho down to 180 km, and apparently represents either a thick lithospheric mantle root or a shallow subducting slab associated with the South Caspian block. This high velocity model may extend to the eastern end of the Greater Caucasus. In addition to the seismological observations, recent geologic studies suggest that the uplift of the Greater Caucasus has occurred primarily over the past 5 Ma. . One of the critical questions related to earthquakes is the existence of deep earthquakes in the northeastern Greater Caucasus. Recent work by the Geophysical Survey of Russia has indicated that seismicity in this region extends to nearly 200 km depth. It is important to confirm these observations and to minimize uncertainties in the depths in order to understand the spatial patterns of these deep earthquakes. Having reliable locations of these events may indicate whether there is a previously undiscovered subduction zone beneath a portion of the Greater Caucasus

  2. On the even greater need for precaution under global change.

    PubMed

    Soskolne, Colin L

    2004-01-01

    The greater the potential for disastrous, large-scale, or catastrophic impacts on health, the greater the case for precaution. The imperative for precautionary action, critical also for downstream determinants of health, is at least as compelling where macro-level concerns about the sustainability of life on the Earth are at issue. In this context, I propose that a higher threshold of uncertainty is needed where large-scale harms to health and well-being are possible. Initial efforts must focus on the training of researchers and risk managers for competencies in complexity, and in systems approaches to transdisciplinary enquiry. Revisiting the intent behind Bradford Hill on causation is an essential first step. Focus on the more proximate causes of diseases, such as those related either to occupational exposures or to more downstream environmental exposures, is left to others in this collection.

    2002-11-01

    Two greater kudu calves (Tragelaphus strepsiceros) born 7 years apart were found with fissures and thickened, scaly, cutaneous plates covering over 80% of their bodies. One was dead at presentation, and the other was euthanized shortly after birth. Both animals shared a common sire. On necropsy, chemosis, ectropion, eclabium, and bilateral valgus deformities of the tarsal joints were observed in one calf, presumed to be secondary to the plates restricting normal fetal development. The principal microscopic lesion was severe lamellar orthokeratosis, with focal mild parakeratosis. Ultrastructural epidermal lesions included the absence of normal lamellar granules, large dilated endoplasmic reticulum, and abnormal retention of organelles and vesicles. Gross, histopathologic, and electron microscopic findings in both kudu calves were consistent with those of harlequin ichthyosis, a rare dermatosis of humans believed to have an autosomal recessive inheritance pattern. The underlying genetic and molecular abnormality and heritability of this condition in this greater kudu herd were not determined.

This 420 square mile area (including Milwaukee County and parts of Waukesha, Racine, Ozaukee and Washington Counties) is home to just over 1 million people. The tables and figures summarize the relative amounts of mercury: annually released from purposeful uses; annually released due to trace impurities; and present or in use from the various source sectors in the Greater Milwaukee Area.

  5. Higher motivation - greater control? The effect of arousal on judgement.

    PubMed

    Riemer, Hila; Viswanathan, Madhu

    2013-01-01

    This research examines control over the effect of arousal, a dimension of affect, on judgement. Past research shows that high processing motivation enhances control over the effects of affect on judgement. Isolating and studying arousal as opposed to valence, the other dimension of affect, and its effect on judgement, we identify boundary conditions for past findings. Drawing from the literature on processes by which arousal influences judgement, we demonstrate that the role of motivation is contingent upon the type of judgement task (i.e., memory- versus stimulus-based judgement). In stimulus-based judgement, individuals exert greater control over the effect of arousal on judgement under low compared to high motivation. In contrast, in memory-based judgement individuals exert greater control over the effect of arousal under high compared to low motivation. Theoretical implications and avenues for future research are discussed.

  6. Trafficking in persons and development: towards greater policy coherence.

    PubMed

    Danailova-Trainor, Gergana; Laczko, Frank

    2010-01-01

    Poverty is often regarded as the "root cause" of trafficking, but the linkages between poverty, a lack of development and trafficking are complex. For example, there is some evidence to suggest that victims of cross-border trafficking are more likely to originate from middle-income rather than lower-income countries. Trafficking and development have tended to be treated as very separate policy areas and the assessment of the development impact of counter-trafficking programmes is still at an early stage. This paper outlines a possible framework for a more evidence-based approach to understanding the linkages between trafficking, trafficking policy and human development. The paper argues that the human development gains from greater mobility could be significantly enhanced if there was greater coherence between policies to combat trafficking and policies to promote development.

  8. Changing Water Environment in the Greater Jakarta Basins

    2014-12-01

    Recent rapid economic development in the greater Jakarta areas has caused not only increased water resources demands but also affects the water environment due to population increase and land use changes, that further causes land degradation, and changes in hydrologic regimes and environmental qualities. In the present study, the water environmental capacities as indicated by the changing landscapes in the greater Jakarta basins were investigated to understand the role of land use management and its impact on water resources, ecosystem and environmental services. The Ciliwung river basin where rapid population increases and progresses of the land use/cover changes occurring was selected as a representative basin, and 41 water samplings were taken at different time of Jan. 08, Apr. 08, Jul. 08, and Oct. 08 during 2009 to understand the effect of rainfall variation on water quality, and clarify the characteristics of hydrological cycle. Landuse changes of the upper basins as can be seen for the upper basin indicated the expansion of settlements during 1990 to 2004 from 4.1% to 17.6% or in acreage increased almost five times, not only converting forested area, but mostly taking place from paddy fields that contributed about 50% of the additional land for new settlements. Urbanization expanding around the greater Jakarta basins, is closely related to the increased fluctuations of river discharges in recent years, with recurrence floods quickly after heavy rainfall events. Furthermore, the study results indicated that water quality of Ciliwung river, especially the loading concentrations of nitric acid closely reflects the population densities of the watershed. These results suggest that the land use/cover changes of the greater Jakarta basins affect largely the change of water environment of the areas and resulting a deteriorated factor for water resources, ecosystems and environmental services in both of quantity and quality

There is one clinally varying subspecies in Eurasia, one that breeds in Greenland, and three in North America, one newly named herein.

  10. From rifting to orogeny; using sediments to unlock the secrets of the Greater Caucasus

    Vincent, Stephen; Guo, Li; Lavrishchev, Vladimir; Maynard, James; Harland, Melise

    2017-04-01

    The western Greater Caucasus formed by the tectonic inversion of the western strand of the Greater Caucasus Basin, a Mesozoic rift that opened at the southern margin of Laurasia. Facies analysis has identified fault-bounded regions of basinal, turbiditic and hemipelagic sediments. These are flanked by areas of marginal, shallow marine sediments to the north and south. Subsidence analysis derived from lithology, thickness and palaeowater depth data indicates that the main phase of rifting occurred during the Aalenian to Bajocian synchronous with that in the eastern Alborz and, possibly, the South Caspian Basin. Secondary episodes of subsidence during the late Tithonian to Berriasian and Hauterivian to early Aptian are tentatively linked to initial rifting within the western, and possibly eastern, Black Sea, and during the late Campanian to Danian to the opening of the eastern Black Sea. Initial uplift, subaerial exposure and sediment derivation from the western Greater Caucasus occurred at the Eocene-Oligocene transition. Oligocene and younger sediments on the southern margin of the former basin were derived from the inverting basin and uplifted parts of its northern margin, indicating that the western Greater Caucasus Basin had closed by this time. The previous rift flanks were converted to flexural basins that accumulated thick, typically hemipelagic and turbiditic sediments in the early, underfilled, stage of their development. A predominance of pollen representing a montane forest environment (dominated by Pinacean pollen) within these sediments suggests that the uplifting Caucasian hinterland had a paleoaltitude of around 2 km from Early Oligocene time. The closure of the western Greater Caucasus Basin and significant uplift of the range at c. 34 Ma is earlier than stated in many studies and needs to be incorporated into geodynamic models for the Arabia-Eurasia region.

    Dietary phosphorus consumption has risen steadily in the United States. Oral phosphorus loading alters key regulatory hormones and impairs vascular endothelial function, which may lead to an increase in left ventricular mass (LVM). We investigated the association of dietary phosphorus with LVM in 4494 participants from the Multi-Ethnic Study of Atherosclerosis, a community-based study of individuals who were free of known cardiovascular disease. The intake of dietary phosphorus was estimated using a 120-item food frequency questionnaire and the LVM was measured using magnetic resonance imaging. Regression models were used to determine associations of estimated dietary phosphorus with LVM and left ventricular hypertrophy (LVH). Mean estimated dietary phosphorus intake was 1167 mg/day in men and 1017 mg/day in women. After adjustment for demographics, dietary sodium, total calories, lifestyle factors, comorbidities, and established LVH risk factors, each quintile increase in the estimated dietary phosphate intake was associated with an estimated 1.1 g greater LVM. The highest gender-specific dietary phosphorus quintile was associated with an estimated 6.1 g greater LVM compared with the lowest quintile. Higher dietary phosphorus intake was associated with greater odds of LVH among women, but not men. These associations require confirmation in other studies.

    Failure of passive transfer (FPT) in captive greater kudu (Tragelaphus strepsiceros) calves can lead to increased morbidity and mortality. In this retrospective study, serum samples from neonatal kudu calves were tested for immunoglobulin using different tests validated for domestic ruminants, including measurement of gamma globulin (GG) measured by protein electrophoresis, total solids (TS) measured by calibrated refractometry, total protein (TP) and globulins measured by colorimetry, gamma glutamyltransferase (GGT), and the zinc sulfate turbidity test (ZSTT). In a logistic regression model, TP, TS, globulins, and the natural log transform of GGT were the only significant parameters associated with FPT. Various historic parameters related to the dam, as well as calf weight, sex, glucose, and packed cell volume, were not significant. Based on the results, FPT in greater kudu is defined as GG of < 0.5 g/dl, a value lower than that in domestic cattle. TS measured by refractometry has an 80% sensitivity and a 100% specificity for FPT in greater kudu. With FPT defined as GG < 0.5 g/dl, kudu calves with a TS < 4.8 g/dl and a negative ZSTT have an increased probability of requiring medical intervention and additional diagnostics may be warranted.

  13. Integrating parasitology and marine ecology: Seven challenges towards greater synergy

    Despite their very different historical origins as scientific disciplines, parasitology and marine ecology have already combined successfully to make important contributions to our understanding of the functioning of natural ecosystems. For example, robust assessments of the contribution of parasites to ecosystem biomass and energetics, and of their impact on community-wide biodiversity and food web structure, have all been made for the first time in marine systems. Nevertheless, for the marriage between parasitology and marine ecology to remain fruitful, several challenges must first be overcome. We discuss seven such challenges on the road to a greater synergy between these disciplines: (1) Raising awareness of parasitism as an ecological force by increasing the proportion of articles about parasites and diseases in marine ecology journals; (2) Making greater use of theory and conceptual frameworks from marine ecology to guide parasitological research; (3) Speeding up or at least maintaining the current rate at which marine parasites are found and described; (4) Elucidating a greater proportion of life cycles in all major groups of marine parasites; (5) Increasing the number of host-parasite model systems on which our knowledge is based; (6) Extending parasitological research offshore and into ocean depths; and (7) Developing, as needed, new epidemiological theory and transmission models for the marine environment. None of these challenges is insurmountable, and addressing just a few of them should guarantee that parasitology and marine ecology will continue to join forces and make further substantial contributions.

  14. More frequent vaginal orgasm is associated with experiencing greater excitement from deep vaginal stimulation.

    Research indicated that: (i) vaginal orgasm (induced by penile-vaginal intercourse [PVI] without concurrent clitoral masturbation) consistency (vaginal orgasm consistency [VOC]; percentage of PVI occasions resulting in vaginal orgasm) is associated with mental attention to vaginal sensations during PVI, preference for a longer penis, and indices of psychological and physiological functioning, and (ii) clitoral, distal vaginal, and deep vaginal/cervical stimulation project via different peripheral nerves to different brain regions. The aim of this study is to examine the association of VOC with: (i) sexual arousability perceived from deep vaginal stimulation (compared with middle and shallow vaginal stimulation and clitoral stimulation), and (ii) whether vaginal stimulation was present during the woman's first masturbation. A sample of 75 Czech women (aged 18-36), provided details of recent VOC, site of genital stimulation during first masturbation, and their recent sexual arousability from the four genital sites. The association of VOC with: (i) sexual arousability perceived from the four genital sites and (ii) involvement of vaginal stimulation in first-ever masturbation. VOC was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites. VOC was also associated with women's first masturbation incorporating (or being exclusively) vaginal stimulation. The findings suggest (i) stimulating the vagina during early life masturbation might indicate individual readiness for developing greater vaginal responsiveness, leading to adult greater VOC, and (ii) current sensitivity of deep vaginal and cervical regions is associated with VOC, which might be due to some combination of different neurophysiological projections of the deep regions and their greater responsiveness to penile stimulation. © 2013 International Society for Sexual Medicine.

    This paper provides an overview of the AMPERE intermodeling comparison with focus on the implications of near-term policies for the costs and attainability of long-term climate objectives. Ten modeling teams participated in the project to explore the consequences of global emissions following the proposed policy stringency of the national pledges from the Copenhagen Accord and Cancún Agreements to 2030. Specific features compared to earlier assessments are the explicit consideration of near-term 2030 emissions targets as well as the systematic sensitivity analysis for the availability and potential of mitigation technologies. Our estimates show that a 2030 mitigation effort comparable to the pledges would result in a further "lock-in" of the energy system into fossil fuels and thus impede the required energy transformation to reach low greenhouse-gas stabilization levels (450ppm CO2e). Major implications include significant increases in mitigation costs, increased risk that low stabilization targets become unattainable, and reduced chances of staying below the proposed temperature change target of 2C. With respect to technologies, we find that following the pledge pathways to 2030 would narrow policy choices, and increases the risks that some currently optional technologies, such as nuclear or carbon capture and storage (CCS), will become "a must" by 2030.

    A number of retail shops in Copenhagen sell fresh cassava roots. Cassava roots contain the toxic cyanogenic glucoside linamarin. A survey was made of the shop characteristics, origin of the roots, buyers, shop owner's knowledge of toxicity levels, and actual toxicity levels. Shops selling fresh cassava were shown mostly to be owned by persons originating in the Middle East or Afghanistan, buyers were found to predominantly be of African origin, and sellers' knowledge concerning the potential toxicity was found to be very restricted. Seventy-six per cent of the roots purchased had a total cyanogenic potentials (CNp) above the 50 mg HCN equivalents kg(-1) dry weight (d.w.) proposed as acceptable by an EU working group. Two of 25 roots purchased had CNp higher than 340 mg HCN eq. kg(-1) d.w. The EU has previously made risk assessments concerning cassava and cyanogenic compounds. In the light of the conclusions drawn, the EU needs to make decisions about how to deal with the regulation and control of fresh cassava roots imported to the European food market. Also cassava root products and cassava leaves should be considered. (c) 2009 Society of Chemical Industry.

    Background Several studies have indicated an association between depression and the development of stroke, but few studies have focused on gender differences, although both depression and stroke are more common in women than in men. The aim of the present study was to describe whether vital exhaustion, a measure of fatigue and depression, prospectively predicts ischemic and hemorrhagic strokes in a large cohort, with particular focus on gender differences. Methods The cohort was composed of 5219 women and 3967 men without cardiovascular disease who were examined in the Copenhagen City Heart Study in 1991–1994. Subjects were followed for 6–9 years. Fatal and nonfatal strokes were ascertained from the Danish National Register of Patients. Cox proportional hazards model was used to describe vital exhaustion as a potential risk factor for stroke. Results Four hundred nine validated strokes occurred. A dose–response relationship between vital exhaustion score and the risk of stroke was found in women reaching a hazard ratio (HR) of 2.27 (95% confidence interval: 1.42–3.62) for the group with the highest score. HR was only slightly attenuated by multivariate adjustment. There was no association between vital exhaustion score and stroke in men. HR was strongest for ischemic stroke, whereas no association was seen for hemorrhagic stroke. Conclusion Vital exhaustion, a measure of fatigue, conveyed an increased risk of ischemic stroke in women, but not in men, in this study sample. PMID:20105695

  18. Theoretical and practical outline of the Copenhagen PACT narrative-based exercise counselling manual to promote physical activity in post-therapy cancer survivors.

    2013-02-01

    Sedentary behaviour and reduced exercise capacity are potential persisting effects of anti-cancer therapy that may predispose to serious health conditions. It is well-established that physical exercise may prevent some of these problems. However, the extent to which cancer survivors are able to adopt long-term physical activity habits depends largely on their motivation. This theoretical paper aims to outline how researchers and practitioners can draw from Antonovsky's salutogenetic theory and White & Epston's Narrative Therapy to develop and implement intervention efforts centered on promotion of long-term physical activity behaviour, while at the same time increasing the individual cancer survivor's sense of meaning and personal health resources. The Copenhagen PACT (Physical Activity after Cancer Treatment) Study targeting adoption and maintenance of regular physical activity in post-therapy cancer survivors is briefly presented including a brief review of the theoretical rationale behind the psychological component of the intervention, i.e. a narrative-based exercise counselling programme. Subsequently, particular attention is given to the core principles, different components and structure of the counselling manual including sample questions and examples of written documents that have emanated from the individual counselling sessions. The discussion includes consideration of some methodological challenges that arise when attempting to evaluate narrative-based interventions in the context of physical activity promotion in cancer rehabilitation and survivorship care.

    Administration of 0.4% clofibrate in the diet stimulated estradiol (E(2))-induced mammary carcinogenesis in the August-Copenhagen Irish (ACI) rat without having an effect on serum levels of E(2). This treatment stimulated by several-fold the NAD(P)H-dependent oxidative metabolism of E(2) and oleyl-CoA-dependent esterification of E(2) to 17beta-oleyl-estradiol by liver microsomes. Glucuronidation of E(2) by microsomal glucuronosyltransferase was increased moderately. In contrast, the activity of NAD(P)H quinone reductase 1 (NQO1), a representative monofunctional phase 2 enzyme, was significantly decreased in liver cytosol of rats fed clofibrate. Decreases in hepatic NQO1 in livers of animals fed clofibrate were noted before the appearance of mammary tumors. E(2) was delivered in cholesterol pellets implanted in 7-8-week-old female ACI rats. The animals received AIN-76A diet containing 0.4% clofibrate for 6, 12 or 28 weeks. Control animals received AIN-76A diet. Dietary clofibrate increased the number and size of palpable mammary tumors but did not alter the histopathology of the E(2)-induced mammary adenocarcinomas. Collectively, these results suggest that the stimulatory effect of clofibrate on hepatic esterification of E(2) with fatty acids coupled with the inhibition of protective phase 2 enzymes, may in part, enhance E(2)-dependent mammary carcinogenesis in the ACI rat model.

  20. Greater deciduous shrub abundance extends tundra peak season and increases modeled net CO2 uptake.

    Satellite studies of the terrestrial Arctic report increased summer greening and longer overall growing and peak seasons since the 1980s, which increases productivity and the period of carbon uptake. These trends are attributed to increasing air temperatures and reduced snow cover duration in spring and fall. Concurrently, deciduous shrubs are becoming increasingly abundant in tundra landscapes, which may also impact canopy phenology and productivity. Our aim was to determine the influence of greater deciduous shrub abundance on tundra canopy phenology and subsequent impacts on net ecosystem carbon exchange (NEE) during the growing and peak seasons in the arctic foothills region of Alaska. We compared deciduous shrub-dominated and evergreen/graminoid-dominated community-level canopy phenology throughout the growing season using the normalized difference vegetation index (NDVI). We used a tundra plant-community-specific leaf area index (LAI) model to estimate LAI throughout the green season and a tundra-specific NEE model to estimate the impact of greater deciduous shrub abundance and associated shifts in both leaf area and canopy phenology on tundra carbon flux. We found that deciduous shrub canopies reached the onset of peak greenness 13 days earlier and the onset of senescence 3 days earlier compared to evergreen/graminoid canopies, resulting in a 10-day extension of the peak season. The combined effect of the longer peak season and greater leaf area of deciduous shrub canopies almost tripled the modeled net carbon uptake of deciduous shrub communities compared to evergreen/graminoid communities, while the longer peak season alone resulted in 84% greater carbon uptake in deciduous shrub communities. These results suggest that greater deciduous shrub abundance increases carbon uptake not only due to greater leaf area, but also due to an extension of the period of peak greenness, which extends the period of maximum carbon uptake.

  1. The post-orgasmic prolactin increase following intercourse is greater than following masturbation and suggests greater satiety.

    Research indicates that prolactin increases following orgasm are involved in a feedback loop that serves to decrease arousal through inhibitory central dopaminergic and probably peripheral processes. The magnitude of post-orgasmic prolactin increase is thus a neurohormonal index of sexual satiety. Using data from three studies of men and women engaging in masturbation or penile-vaginal intercourse to orgasm in the laboratory, we report that for both sexes (adjusted for prolactin changes in a non-sexual control condition), the magnitude of prolactin increase following intercourse is 400% greater than that following masturbation. The results are interpreted as an indication of intercourse being more physiologically satisfying than masturbation, and discussed in light of prior research reporting greater physiological and psychological benefits associated with coitus than with any other sexual activities.

    2005-01-01

    A new land cover database of Greater Mesoamerica has been prepared using moderate resolution imaging spectroradiometer (MODIS, 500 m resolution) satellite data. Daily surface reflectance MODIS data and a suite of ancillary data were used in preparing the database by employing a decision tree classification approach. The new land cover data are an improvement over traditional advanced very high resolution radiometer (AVHRR) based land cover data in terms of both spatial and thematic details. The dominant land cover type in Greater Mesoamerica is forest (39%), followed by shrubland (30%) and cropland (22%). Country analysis shows forest as the dominant land cover type in Belize (62%), Cost Rica (52%), Guatemala (53%), Honduras (56%), Nicaragua (53%), and Panama (48%), cropland as the dominant land cover type in El Salvador (60.5%), and shrubland as the dominant land cover type in Mexico (37%). A three-step approach was used to assess the quality of the classified land cover data: (i) qualitative assessment provided good insight in identifying and correcting gross errors; (ii) correlation analysis of MODIS- and Landsat-derived land cover data revealed strong positive association for forest (r2 = 0.88), shrubland (r2 = 0.75), and cropland (r2 = 0.97) but weak positive association for grassland (r2 = 0.26); and (iii) an error matrix generated using unseen training data provided an overall accuracy of 77.3% with a Kappa coefficient of 0.73608. Overall, MODIS 500 m data and the methodology used were found to be quite useful for broad-scale land cover mapping of Greater Mesoamerica.

  3. Sexual predators, energy development, and conservation in greater Yellowstone.

    2010-06-01

    In the United States, as elsewhere, a growing debate pits national energy policy and homeland security against biological conservation. In rural communities the extraction of fossil fuels is often encouraged because of the employment opportunities it offers, although the concomitant itinerant workforce is often associated with increased wildlife poaching. We explored possible positive and negative factors associated with energy extraction in the Greater Yellowstone Ecosystem (GYE), an area known for its national parks, intact biological diversity, and some of the New World's longest terrestrial migrations. Specifically, we asked whether counties with different economies-recreation (ski), agrarian (ranching or farming), and energy extractive (petroleum)-differed in healthcare (gauged by the abundance of hospital beds) and in the frequency of sexual predators. The absolute and relative frequency of registered sex offenders grew approximately two to three times faster in areas reliant on energy extraction. Healthcare among counties did not differ. The strong conflation of community dishevel, as reflected by in-migrant sexual predators, and ecological decay in Greater Yellowstone is consistent with patterns seen in similar systems from Ecuador to northern Canada, where social and environmental disarray exist around energy boomtowns. In our case, that groups (albeit with different aims) mobilized campaigns to help maintain the quality of rural livelihoods by protecting open space is a positive sign that conservation can matter, especially in the face of rampant and poorly executed energy extraction projects. Our findings further suggest that the public and industry need stronger regulatory action to instill greater vigilance when and where social factors and land conversion impact biological systems.

  4. Practicing more retrieval routes leads to greater memory retention.

    A wealth of research has shown that retrieval practice plays a significant role in improving memory retention. The current study focused on one simple yet rarely examined question: would repeated retrieval using two different retrieval routes or using the same retrieval route twice lead to greater long-term memory retention? Participants elaborately learned 22 Japanese-Chinese translation word pairs using two different mediators. Half an hour after the initial study phase, the participants completed two retrieval sessions using either one mediator (Tm1Tm1) or two different mediators (Tm1Tm2). On the final test, which was performed 1week after the retrieval practice phase, the participants received only the cue with a request to report the mediator (M1 or M2) followed by the target (Experiment 1) or only the mediator (M1 or M2) with a request to report the target (Experiment 2). The results of Experiment 1 indicated that the participants who practiced under the Tm1Tm2 condition exhibited greater target retention than those who practiced under the Tm1Tm1 condition. This difference in performance was due to the significant disadvantage in mediator retrieval and decoding of the unpracticed mediator under the Tm1Tm1 condition. Although mediators were provided to participants on the final test in Experiment 2, decoding of the unpracticed mediators remained less effective than decoding of the practiced mediators. We conclude that practicing multiple retrieval routes leads to greater memory retention than focusing on a single retrieval route. Thus, increasing retrieval variability during repeated retrieval practice indeed significantly improves long-term retention in a delay test.

  5. Greater Burgan of Kuwait: world's second largest oil field

    1989-03-01

    Greater Burgan (Main burgan, Magwa, and Ahmadi) field is located in the Arabian Platform geologic province and the stable shelf tectonic environment of the Mesopotamian geosyncline, a sedimentary basin extending from the Arabian shield on the west to the complexly folded and faulted Zagros Mountains on the east. The structural development in Cretaceous time represents a major anticlinorium bounded by a basin to the west and a synclinorium to the east. Greater Burgan is located within this anticlinorium. The field consists of three dome structures 25 km wide and 65 km long with gentle dips of only few degrees. Faults have little throw and did not contribute to the trapping mechanism. The structural deformation may have been caused by halokinetic movements and most likely by basement block faulting that may have started in the Paleozoic. Greater Burgan was discovered in 1938. All production during the last 40 years has been by its natural pressure. Although natural gas injection has been carried out for some time, no waterflooding has been initiated yet. Recoverable reserves of the field are 87 billion bbl of oil. During the last 5 years giant reserves have been added in this field from the deeper strata of Jurassic age. Several deep wells have been drilled to the Permian for the purpose of discovering gas. So far, no Permian gas has been found in Kuwait. The Permian is 25,000 ft deep, and it is unlikely gas will be found there in the future. However, the potential of the Jurassic reservoirs will be a major target in the future. Also, there is a great possibility of discovering oil in stratigraphic traps, as several producing strata in the nearby fields pinch out on the flanks of this giant structure. Enhanced oil recovery should add significant reserves in the future.

  6. Ultradeep (greater than 300 kilometers), ultramafic upper mantle xenoliths.

    PubMed

    Haggerty, S E; Sautter, V

    1990-05-25

    Geophysical discontinuities in Earth's upper mantle and experimental data predict the structural transformation of pyroxene to garnet and the solid-state dissolution of pyroxene into garnet with increasing depth. These predictions are indirectly verified by omphacitic pyroxene exsolution in pyropic garnet-bearing xenoliths from a diamondiferous kimberlite. Conditions for silicon in octahedral sites in the original garnets are met at pressures greater than 130 kilobars, placing the origin of these xenoliths at depths of 300 to 400 kilometers. These ultradeep xenoliths support the theory that the 400-km seismic discontinuity is marked by a transition from peridotite to eclogite.

    Aim: Greater sage-grouse (Centrocercus urophasianus), a shrub-steppe obligate species of western North America, currently occupies only half its historical range. Here we examine how broad-scale, long-term trends in landscape condition have affected range contraction. Location: Sagebrush biome of the western USA. Methods: Logistic regression was used to assess persistence and extirpation of greater sage-grouse range based on landscape conditions measured by human population (density and population change), vegetation (percentage of sagebrush habitat), roads (density of and distance to roads), agriculture (cropland, farmland and cattle density), climate (number of severe and extreme droughts) and range periphery. Model predictions were used to identify areas where future extirpations can be expected, while also explaining possible causes of past extirpations. Results: Greater sage-grouse persistence and extirpation were significantly related to sagebrush habitat, cultivated cropland, human population density in 1950, prevalence of severe droughts and historical range periphery. Extirpation of sage-grouse was most likely in areas having at least four persons per square kilometre in 1950, 25% cultivated cropland in 2002 or the presence of three or more severe droughts per decade. In contrast, persistence of sage-grouse was expected when at least 30 km from historical range edge and in habitats containing at least 25% sagebrush cover within 30 km. Extirpation was most often explained (35%) by the combined effects of peripherality (within 30 km of range edge) and lack of sagebrush cover (less than 25% within 30 km). Based on patterns of prior extirpation and model predictions, we predict that 29% of remaining range may be at risk. Main Conclusions: Spatial patterns in greater sage-grouse range contraction can be explained by widely available landscape variables that describe patterns of remaining sagebrush habitat and loss due to cultivation, climatic trends, human

  9. The new EU healthcare rights directive: greater uniformity?

    PubMed

    McHale, Jean V

    On 9th March 2011 the new EU Directive on Patients' Rights in Cross-border Healthcare was adopted. This article explores its implications for the delivery of health care in the UK. It notes that the final version of the Directive provides much greater discretion to member states to control access to resources than was suggested in early drafts of the Directive. It explores the situations in which care can be subject to prior authorization and suggests that perhaps the greatest long-term impact of the Directive will not be in patient mobility as such but rather in relation to its impact on broader standard setting across the EU.

    We present a synthesis of the state of knowledge concerning the species of Passalidae (Coleoptera) of the West Indies and we present a key to the species. The recently described genus Antillanax Boucher renders the subgenus Passalus (Pertinax) Kaup paraphyletic, therefore we place Antillanax in synonymy with Passalus (Pertinax) and we propose a new combination for Passalus (Pertinax) doesburgi (Boucher). The island richest in species is Hispaniola, with five species, three of them endemic. Excluding Trinidad and Tobago, the passalid fauna of the West Indies comprises 13 species; this is low richness, but with high endemism (50%), especially for the Greater Antilles.

    Although DNA absorption at wavelengths greater than 300 nm is much weaker than that at shorter wavelengths, this absorption seems to be responsible for much of the biological damage caused by solar radiation of wavelengths less than 320 nm. Accurate measurement of the absorption spectrum of DNA above 300 nm is complicated by turbidity characteristic of concentrated solutions of DNA. We have measured the absorption spectra of DNA from calf thymus, Clostridium perfringens, Escherichia coli, Micrococcus luteus, salmon testis, and human placenta using procedures which separate optical density due to true absorption from that due to turbidity. Above 300 nm, the relative absorption of DNA increases as a function of guanine-cytosine content, presumably because the absorption of guanine is much greater than the absorption of adenine at these wavelengths. This result suggests that the photophysical processes which follow absorption of a long-wavelength photon may, on the average, differ from those induced by shorter-wavelength photons. It may also explain the lower quantum yield for the killing of cells by wavelengths above 300 nm compared to that by shorter wavelengths.

    Natural gas is seen by many as the future of American energy: a fuel that can provide energy independence and reduce greenhouse gas emissions in the process. However, there has also been confusion about the climate implications of increased use of natural gas for electric power and transportation. We propose and illustrate the use of technology warming potentials as a robust and transparent way to compare the cumulative radiative forcing created by alternative technologies fueled by natural gas and oil or coal by using the best available estimates of greenhouse gas emissions from each fuel cycle (i.e., production, transportation and use). We find that a shift to compressed natural gas vehicles from gasoline or diesel vehicles leads to greater radiative forcing of the climate for 80 or 280 yr, respectively, before beginning to produce benefits. Compressed natural gas vehicles could produce climate benefits on all time frames if the well-to-wheels CH4 leakage were capped at a level 45–70% below current estimates. By contrast, using natural gas instead of coal for electric power plants can reduce radiative forcing immediately, and reducing CH4 losses from the production and transportation of natural gas would produce even greater benefits. There is a need for the natural gas industry and science community to help obtain better emissions data and for increased efforts to reduce methane leakage in order to minimize the climate footprint of natural gas.

    Greater Sage-grouse (Centrocercus urophasianus) are a species of concern due to shrinking populations associated with habitat fragmentation and loss. Baseline health parameters for this species are limited or lacking, especially with regard to tissue metal concentrations. To obtain a range of tissue metal concentrations, livers were collected from 71 Greater Sage-grouse from Wyoming and Montana. Mean +/- SE metal concentrations (mg/kg wet weight) in liver were determined for vanadium (V) (0.12 +/- 0.01), chromium (Cr) (0.50 +/- 0.02), manganese (Mn) (2.68 +/- 0.11), iron (Fe) (1,019 +/- 103), nickel (Ni) (0.40 +/- 0.04), cobalt (Co) (0.08 +/- 0.02), copper (Cu) (6.43 +/- 0.40), mercury (Hg) (0.30 +/- 0.09), selenium (Se) (1.45 +/- 0.64), zinc (Zn) (59.2 +/- 4.70), molybdenum (Mo) (0.93 +/- 0.07), cadmium (Cd) (1.44 +/- 0.14), barium (Ba) (0.20 +/- 0.03), and lead (Pb) (0.17 +/- 0.03). In addition to providing baseline data, metal concentrations were compared between sex, age (juvenile/adult), and West Nile virus (WNv) groups (positive/negative). Adult birds had higher concentrations of Ni and Cd compared to juveniles. In addition, Zn and Cu concentrations were significantly elevated in WNv-positive birds.

    Ratite anesthetic events are often dangerous because these birds use their powerful legs and clawed feet as a defense, and physical restraint can result in self-trauma or injury to handlers. Although various combinations of opioids, alpha-2 adrenergic agonists, and dissociative agents have been employed in ratites, few effective chemical immobilization protocols have been documented for rheas (Rhea spp.). An intramuscular, remote-delivered combination of thiafentanil (0.30 +/- 0.08 mg/kg), dexmedetomidine (7.31 +/- 2.72 microg/kg), and tiletamine-zolazepam (5.09 +/- 2.31 mg/kg) was utilized in eight adult (four male, four female) greater rheas (Rhea americana). Smooth inductions were observed. During clinical procedures, birds were intubated and maintained on isoflurane gas, and atipamezole was administered to antagonize the dexmedetomidine. At recovery, naltrexone was administered to antagonize the thiafentanil, and midazolam was administered to smooth crate recoveries until release. This low-volume, high-potency, reversible drug combination demonstrated safe inductions and smooth recoveries and proved to be a reliable anesthetic regimen for greater rheas.

    We studied the highest reported number of patients with occult fracture of the greater tuberosity of the humerus and we analysed why fracture was not diagnosed, shoulder function and prevalence of eventually associated rotator cuff tear (RCT). Twenty-four patients with a missed fracture of the greater tuberosity underwent MR study for a suspect RCT. We evaluated shoulder function and self-assessed comfort with the Constant score (CS) and Simple Shoulder Test (SST). Nine patients showed evidence of cuff tendinosis, 11 of partial (p) RCT (2: subscapularis; 6: supraspinatus and 3: supraspinatus and infraspinatus). All patients with pRCT were older than 40. Initially, the mean CS and SST were 54% and 5/12; at follow-up, values increased to 36% and 5 points. MR should be performed in patients apparently negative for fracture but with painful shoulders and decreased ROM. Of our patients, 45.8% had pRCT; nevertheless function recovery was verified in 16 weeks.

    Introduction: Shoulder dislocations are a very common entity in routine orthopaedic practice. Chronic unreduced anterior dislocations of the shoulder are not very common. Neurological and vascular complications may occur as a result of an acute anterior dislocation of the shoulder or after a while in chronic unreduced shoulder dislocation. Open reduction is indicated for most chronic shoulder dislocations. We report a case of neglected bilateral anterior shoulder dislocation with bilateral displaced greater tuberosity fracture. To the best of our knowledge, only a handful cases have been reported in literature with bilateral anterior shoulder dislocation with bilateral fractures. Delayed diagnosis/reporting is a scenario which makes the list even slimmer and management all the more challenging. Case Report: We report a case of a 35-year-old male who had bilateral anterior shoulder dislocation and bilateral greater tuberosity fracture post seizure and failed to report it for a period of 30 days. One side was managed conservatively with closed reduction and immobilization and the other side with open reduction. No neurovascular complications pre or post reduction of shoulder were seen. Conclusion: Shoulder dislocations should always be suspected post seizures and if found should be treated promptly. Treatment becomes difficult for any shoulder dislocation that goes untreated for considerable period of time PMID:27703939

    Low-level radioactive wastes include a broad spectrum of wastes that have different radionuclide concentrations, half-lives, and physical and chemical properties. Standard shallow-land burial practice can provide adequate protection of public health and safety for most low-level wastes, but a small volume fraction (about 1%) containing most of the activity inventory (approx.90%) requires specific measures known as ''greater-confinement disposal'' (GCD). Different site characteristics and different waste characteristics - such as high radionuclide concentrations, long radionuclide half-lives, high radionuclide mobility, and physical or chemical characteristics that present exceptional hazards - lead to different GCD facility design requirements. Facility design alternatives considered for GCD include the augered shaft, deep trench, engineered structure, hydrofracture, improved waste form, and high-integrity container. Selection of an appropriate design must also consider the interplay between basic risk limits for protection of public health and safety, performance characteristics and objectives, costs, waste-acceptance criteria, waste characteristics, and site characteristics. This paper presents an overview of the factors that must be considered in planning the application of methods proposed for providing greater confinement of low-level wastes. 27 refs.

    Despite improved precision of component placement and consistent and accurate restoration of neutral limb alignment, controversy persists regarding the clinical benefits of computer-assisted total knee arthroplasty (TKA). Computer-assisted TKA provides excellent information regarding gap equality and symmetry throughout the knee range of motion and allows precise, quantitative soft tissue release for deformities, especially in knees with severe flexion contractures and severe rigid valgus deformities. Hence accurate restoration of gap balance, joint line, and posterior femoral offset consequently improves functional results. Knee arthritis with complex extra-articular deformities and in situ hardware can be tackled appropriately using computer navigation where conventional techniques may be inadequate. It also allows intra-articular correction for extra-articular deformities due to malunions and facilitates extra-articular correction in cases with severe extra-articular tibial deformities. In obese patients, where the alignment of the limb is difficult to assess, computer navigation improves accuracy and reduces the number of outliers. The ability to quantify the precise amount of bone cuts and soft tissue releases needed to equalize gaps and restore alignment, reduced blood loss, and incidence of systemic emboli improves the safety of the procedure and hastens functional recovery of the patient. Hence, computer-assisted TKA not only provides greater precision, but also greater clinical benefit.

  1. Spatial variations in travel behavior within greater Toronto area

    1998-03-01

    Rapid suburbanization of housing and employment has produced severe traffic congestion in North American cities. One response to this problem in the greater Toronto area (GTA) has been to identify urban forms that are more supportive of public transport and require less vehicle kilometers of travel to support. The analytical tools used to assess the travel implications of different urban forms normally use travel demand parameters that are uniform across an area. This has yielded misleading estimates of travel demands. This paper describes analyses of the intraregional differences in travel behavior in the greater Toronto area. The analyses described are at two spatial scales: the suburb (municipality/planning district) level and the much finer traffic analysis zone level. The analysis units were grouped into high-growth, developing,a nd low-growth categories at both spatial scales. The analyses reported in this paper show that household characteristics and travel behavior are quite similar for both established and redeveloping zones in the older, stable suburbs. Significant differences in travel characteristics exist between the older, established zones and the growing zones in the developing suburbs. Household trip rates are shown to vary with household size, car ownership, and whether a household is located in a stable or growing suburb. Accessibility to public transport is shown to affect trip behavior differently in growing areas than in established areas. The paper concludes by discussing the public policy and transport systems analysis implications of the results.

    Results of a low-temperature thermochronometric study are presented that provide new constraints on the spatial and temporal patters of exhumation in the central and eastern Greater Caucasus. This study employed a range of thermochronomtric systems with thermal sensitivity below ~250°C, including ZFT, 40Ar/39Ar, AFT, and apatite and zircon (U-Th)/He. Granitic samples from the central Greater Caucasus in Russia were collected primarily along two N-S transects between Mt. Elbrus and Mt. Kazbek, at ~43.25°E and 43.75°E. ZFT and 40Ar/39Ar results from these samples are Late Paleozoic in age, consistent with regional igneous cooling ages perhaps related to the Variscan orogeny. AFT and (U-Th)/He results indicate slow (<4°C/Myr) cooling from at least 30 until ~5Ma, at which time the rate of cooling sharply increased to ~ 25°C/Myr. These data constrain total exhumation of the central Greater Caucasus to ~10 km, with at least half of this total having been exhumed since the end of the Miocene. The initiation of the first phase of slow exhumation in the central Greater Caucasus is poorly constrained by our rapidly exhumed sample suite, but one slowly cooled sample from the northern edge of the range suggests exhumation may have begun in the Oligocene. No evidence is preserved in the thermochronometric data for an Eocene exhumational event related to the proposed onset of continental-continental collision at this time, but pre-Oligocene exhumation can be constrained by our data to be less than 1-2 km, assuming simple, monotonic cooling. Low-temperature thermochronometry of volcaniclastic rocks from the eastern Caucasus in Azerbaijan (~48.25°E) yield a markedly different story. Cretaceous AFT ages are consistent with stratigraphic estimates of the eruptive age of the volcaniclastic sequence, while (U-Th)/He ages are reset, limiting burial and re-exhumation since the Mesozoic to ~3 km. Rapid exhumation of these rocks began ~3 Ma, and well-preserved post-Mesozoic thermal

    Angiostrongylus vasorum is a parasitic nematode that can cause serious and potentially fatal disease in dogs and other canids. The aim of this study was to determine the intermediate slug species infected in nature by sampling sites in Greater London and Hertfordshire located within a known hyperendemic region. Overall, A. vasorum larvae were recovered from 6/381 slugs (1.6%) by tissue digestion, and their identity was confirmed by PCR. Infected slugs originated from three different sites in the Greater London area: one in Waltham Forest and two in Bromley. Slugs parasitised by A. vasorum were identified by a combination of external morphological characteristics and molecular techniques and belonged to three different families: the Arionidae, the Milacidae and the Limacidae. This includes two new host records for the parasite: Arion distinctus and Tandonia sowerbyi. This is the first record of A. vasorum in the family Milacidae, indicating that the parasite has a broader intermediate host range than previously recognised.

    Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute greater relative changes in thermal balance at colder sites. To test this hypothesis, we examined up to 20 years of phenology data for 47 tundra plant species at 18 high-latitude sites along a climatic gradient. Across all species, the timing of leaf emergence and flowering was more sensitive to a given increase in summer temperature at colder than warmer high-latitude locations. A similar pattern was seen over time for the flowering phenology of a widespread species, Cassiope tetragona. These are among the first results highlighting differential phenological responses of plants across a climatic gradient and suggest the possibility of convergence in flowering times and therefore an increase in gene flow across latitudes as the climate warms.

    Greater celandine, similarly as other plants of the family Papaveraceae, produces benzylisoquinoline alkaloids, primarily benzophenanthridines. Polyphenoloxidase (PPO) is most probably involved in the formation of dopamine, which is one of the precursors of norcoclaurine, the first intermediate with the benzylisoquinoline structure. This study has revealed that PPO present in the latex of greater celandine is localized in the organelles, which serve to store alkaloids (the so-called 1000 g organelles). The enzyme was purified by means of affinity chromatography into electrophoretic homogeneity. It possesses a relative molecular mass of approximately 65 kDa and exerts two activities, the monophenolase and diphenolase ones. With the use of a polymerase chain reaction, it was possible to amplify a part of the PPO gene from the region of the active site.

    Recent and previously published mapping in the Nar valley, north of the Annapurna massif in central Nepal, recognised an enigmatic metamorphic culmination of the Greater Himalayan sequence, surrounded by rocks correlated with the Tethyan sedimentary sequence. The map area is re-interpreted as two structural levels within the Greater Himalayan sequence. The Lower Level is correlated to the well-studied Greater Himalayan sequence of the Annapurna region, based on characteristic rock types, high-strain zones with south-verging shear-sense indicators, and high-grade metamorphism. The rocks of the Upper Level, previously mapped as the sub-greenschist or zeolite facies Tethyan sedimentary sequence, are garnet-bearing schists. Petrography and garnet-biotite thermometry suggest the Upper Level equilibrated at amphibolite facies (500-650 °C). These results support the recent contention that the Upper Level rocks are a component of the Greater Himalayan sequence, and thus indicate that components of the Himalayan metamorphic core vary considerably along strike. Structural, metamorphic and age constraints are integrated into a cohesive regional tectonometamorphic model. The Lower and Upper Levels both experienced D 1 deformation and peak metamorphism before ˜20 Ma. The Lower and Upper Levels were juxtaposed along the synmetamorphic Chame detachment after 20 Ma during retrograde metamorphism. After ˜19 Ma, the Phu detachment placed the unmetamorphosed Tethyan sedimentary sequence above the Lower and Upper Levels. The entire package was then subsequently folded, after 19 Ma, by a non-cylindrical antiform-synform pair with a ˜25 km wavelength creating an apparent dome. The proposed tectonometamorphic model reconciles previously contradictory interpretations of the transition between metamorphic core and overlying sediments in the Nar valley.

  8. Energetics of reproduction in female and male greater snow geese.

    1995-08-01

    Arctic-nesting geese are classified as "capital" breeders (i.e., birds that rely largely on endogenous reserves to meet the high nutrient requirement of clutch formation) as opposed to "income" breeders (those that rely directly on ingested food). However, some evidence has suggested that energy reserves of greater snow geese (Chen caerulescens atlantica) are not sufficient to meet these costs. We tested whether greater snow geese were capital breeders and examined the consequences on their reproductive strategy. We collected 48 females and 47 males from arrival at the breeding colony on Bylot Island (NWT) to the postlaying stage, and determined fat and protein content in somatic and reproductive tissues. Rapid follicular growth was initiated only after arrival on the breeding ground. Somatic fat of females tended to increase during the prelaying and laying stages at the same time that most of the fat was deposited in developing follicles. Decrease in somatic fat in postlaying females was mostly related to its use for meeting metabolic requirements during early incubation. Hence, almost all fat invested in the clutch came from food intake, not endogenous reserves. Somatic protein was maintained during prelaying but decreased during laying, suggesting that some protein reserves were deposited in the eggs. There was no relationship between somatic fat and the number of developing follicles (incubating females excluded) but a relationship was found with somatic protein. Clutch size was not related to body size. In males, somatic fat, which was similar to females at arrival, was almost completely depleted by the postlaying stage. Male somatic protein remained stable. Male somatic reserves were not related to the somatic reserves, clutch size or nutrient investment in reproduction of their mate. We conclude that, in female greater snow geese, little fat reserves (if any) were used for egg formation though some protein reserves were used, whereas males relied heavily on

    I examined the relationship of recalled and diary recorded frequency of penile-vaginal intercourse (FSI), noncoital partnered sexual activity, and masturbation to measured waist and hip circumference in 120 healthy adults aged 19-38. Slimmer waist (in men and in the sexes combined) and slimmer hips (in men and women) were associated with greater FSI. Slimmer waist and hips were associated with rated importance of intercourse for men. Noncoital partnered sexual activity had a less consistent association with slimness. Slimmer waist and hips were associated with less masturbation (in men and in the sexes combined). I discuss the results in terms of differences between different sexual behaviors, attractiveness, emotional relatedness, physical sensitivity, sexual dysfunction, sociobiology, psychopharmacological aspects of excess fat and carbohydrate consumption, and implications for sex therapy.

  10. Risks of Brucella abortus spillover in the Greater Yellowstone area.

    PubMed

    2013-04-01

    Recurrent spillover of Brucella abortus from wildlife reservoirs to domestic cattle in the Greater Yellowstone Area (GYA) has prevented the United States from completely eradicating bovine brucellosis. Risks to cattle are a function of the size and location of wildlife and livestock populations, the degree and nature of spatio-temporal interactions between the various hosts, the level of disease in wildlife, and the susceptibility of livestock herds. While the brucellosis prevalence in wild, free-ranging GYA bison (Bison bison) is high, current management actions have successfully limited contact between bison and cattle. Under current management practices, the risks to cattle in the GYA are predominantly from wild elk (Cervus elaphus). Intra- and inter-species transmission events, while uncommon, are nevertheless crucial for the maintenance of brucellosis in the GYA. Future management actions should focus on decreasing elk herd densities and group sizes and on understanding the behavioural and environmental drivers that result in co-mingling that makes transmission possible.

This inventory provides information that might be helpful in planning the best and most beneficial use of lakes in an area of rapid population growth. The report includes data on lake size and water quality. Size data are included on most of the lakes of 2 hectares (20,000 m2, or about 5 acres) or greater, and water-quality data are provided on most lakes larger than 10 hectares (about 25 acres). Bodies of water resulting form excavation of gravel (borrow pits) were generally not included in the inventory.

    We propose that dishonest and creative behavior have something in common: They both involve breaking rules. Because of this shared feature, creativity may lead to dishonesty (as shown in prior work), and dishonesty may lead to creativity (the hypothesis we tested in this research). In five experiments, participants had the opportunity to behave dishonestly by overreporting their performance on various tasks. They then completed one or more tasks designed to measure creativity. Those who cheated were subsequently more creative than noncheaters, even when we accounted for individual differences in their creative ability (Experiment 1). Using random assignment, we confirmed that acting dishonestly leads to greater creativity in subsequent tasks (Experiments 2 and 3). The link between dishonesty and creativity is explained by a heightened feeling of being unconstrained by rules, as indicated by both mediation (Experiment 4) and moderation (Experiment 5).

  14. Discrimination reversal learning reveals greater female behavioural flexibility in guppies

    2014-01-01

    Behavioural flexibility allows an animal to adapt its behaviour in response to changes in the environment. Research conducted in primates, rodents and domestic fowl suggests greater behavioural persistence and reduced behavioural flexibility in males. We investigated sex differences in behavioural flexibility in fish by comparing male and female guppies (Poecilia reticulata) in a reversal learning task. Fish were first trained on a colour discrimination, which was learned equally rapidly by males and females. However, once the reward contingency was reversed, females were better at inhibiting the previous response and reached criterion twice as fast as males. When reward reversing was repeated, males gradually reduced the number of errors, and the two sexes had a comparable performance after four reversals. We suggest that sex differences in behavioural flexibility in guppies can be explained in terms of the different roles that males and females play in reproduction.

    Four quasars with redshifts greater than four were detected in a low-resolution CCD grism survey. CCD photometry and high S/N, moderate resolution spectra are presented for these quasars and the six other known quasars with redshifts above 4. The M sub B values of nine of the objects are between -27.5 and -25, with the tenth quasar having an M sub B value of -29. The emission lines and shapes of the continua of these ten quasars are similar to those of lower-redshift quasars. The results suggest that the C IV emission lines in high-redshift quasars may be weaker than those in lower-redshift quasars. The continua of all of the high-redshift quasars display strong depressions blueward of the Ly-alpha emission line.

    Intimate partner violence affects millions of people globally. One possible contributing factor is poor self-control. Self-control requires energy, part of which is provided by glucose. For 21 days, glucose levels were measured in 107 married couples. To measure aggressive impulses, each evening participants stuck between 0 and 51 pins into a voodoo doll that represented their spouse, depending how angry they were with their spouse. To measure aggression, participants competed against their spouse on a 25-trial task in which the winner blasted the loser with loud noise through headphones. As expected, the lower the level of glucose in the blood, the greater number of pins participants stuck into the voodoo doll, and the higher intensity and longer duration of noise participants set for their spouse.

On average 61% of students in the European region had consumed alcohol in the last 30 days and 43% had participated in binge drinking in the same period. This article investigates the prevalence of adolescent binge drinking and the factors associated with this prevalence in urban areas of Greater Manchester. Data were obtained from the youth survey of the European Urban Health Indicator System 2 project. Study participants were school students aged 14-16 from the urban areas of Greater Manchester. The main outcome measures were adolescent binge drinking prevalence in Greater Manchester and the socio-demographic factors influencing it. Greater Manchester had an adolescent binge drinking prevalence of 49.8%. Individual factors associated with increased prevalence of binge drinking were: age, substance use, school performance and early initiation of drinking (all significant at χ(2), P < 0.05). Peer factors associated with increased prevalence of binge drinking were spending evenings with friends, keeping in touch with friends, having a good relationship with peers and self-reported bullying behaviours (all significant at χ(2), P < 0.05). Family support lowered the prevalence of adolescent binge drinking. Conduct problems, family affluence and perceived local crime increased the prevalence of adolescent binge drinking. Binge drinking is highly prevalent in Greater Manchester adolescents. Various individual, peer-related, family-related and community-related factors were associated with this problem. Any attempt to tackle the prevalence of adolescent binge drinking must take into account all of these factors. © The Author 2015.

    Over one-third of breast cancer survivors experience upper extremity disability. Black women present with factors associated with greater upper extremity disability, including: increased body mass index (BMI), more advanced disease stage at diagnosis, and varying treatment type compared with Whites. No prior research has evaluated the relationship between race and upper extremity disability using validated tools and controlling for these factors. Data were drawn from a survey study among 610 women with stage I-III hormone receptor positive breast cancer. The disabilities of the arm, shoulder and hand (QuickDASH) is an 11-item self-administered questionnaire that has been validated for breast cancer survivors to assess global upper extremity function over the past 7 days. Linear regression and mediation analysis estimated the relationships between race, BMI and QuickDASH score, adjusting for demographics and treatment types. Black women (n = 98) had 7.3 points higher average QuickDASH scores than White (n = 512) women (p < 0.001). After adjusting for BMI, age, education, cancer treatment, months since diagnosis, and aromatase inhibitor status, Black women had an average 4-point (95 % confidence interval 0.18-8.01) higher QuickDASH score (p = 0.04) than White women. Mediation analysis suggested that BMI attenuated the association between race and disability by 40 %. Even several years post-treatment, Black breast cancer survivors had greater upper extremity disability, which was partially mediated by higher BMIs. Close monitoring of high BMI Black women may be an important step in reducing disparities in cancer survivorship. More research is needed on the relationship between race, BMI, and upper extremity disability.

    Studies of female waterfowl nutrient reserve use during egg production require a precise understanding of ovarian follicle dynamics to correctly interpret breeding status, and, therefore, derive proper inference. Concerns over numerical declines of North American scaup have increased the need to better understand the role of female condition in reproductive performance. We quantified ovarian follicle dynamics of female Greater Scaup (Aythya marila) breeding on the Yukon–Kuskokwim Delta, Alaska, using a method that accounts for within day variation in follicle size. We considered several models for describing changes in follicle growth with the best supported model estimating the duration of rapid follicle growth (RFG) to be 5.20 ± 0.52 days (±95% confidence intervals) for each developing follicle. Average diameter and dry mass of preovulatory follicles were estimated to be 9.36 mm and 0.26 g, respectively, at the onset of RFG, and these follicle characteristics were 41.47 mm and 15.57 g, respectively, at ovulation. The average diameter of postovulatory follicles immediately following ovulation was estimated to be 17.35 mm, regressing quickly over several days. In addition, we derived predictive equations using diameter and dry mass to estimate the number of days before, and after, ovulation for pre- and postovulatory follicles, as well as an equation to estimate dry mass of damaged follicles. Our results allow precise definition of RFG and nest initiation dates, clutch size, and the daily energetic and nutritional demands of egg production at the individual level. This study provides the necessary foundation for additional work on Greater Scaup reproductive energetics and physiology, and offers an approach for quantifying ovarian follicle dynamics in other species.

  20. Greater learnability is not sufficient to produce cultural universals

    Looking across human societies reveals regularities in the languages that people speak and the concepts that they use. One explanation that has been proposed for these “cultural universals” is differences in the ease with which people learn particular languages and concepts. A difference in learnability means that languages and concepts possessing a particular property are more likely to be accurately transmitted from one generation of learners to the next. Intuitively, this difference could allow languages and concepts that are more learnable to become more prevalent after multiple generations of cultural transmission. If this is the case, the prevalence of languages and concepts with particular properties can be explained simply by demonstrating empirically that they are more learnable. We evaluate this argument using mathematical analysis and behavioral experiments. Specifically, we provide two counter-examples that show how greater learnability need not result in a property becoming prevalent. First, more learnable languages and concepts can nonetheless be less likely to be produced spontaneously as a result of transmission failures. We simulated cultural transmission in the laboratory to show that this can occur for memory of distinctive items: these items are more likely to be remembered, but not generated spontaneously once they have been forgotten. Second, when there are many languages or concepts that lack the more learnable property, sheer numbers can swamp the benefit produced by greater learnability. We demonstrate this using a second series of experiments involving artificial language learning. Both of these counter-examples show that simply finding a learnability bias experimentally is not sufficient to explain why a particular property is prevalent in the languages or concepts used in human societies: explanations for cultural universals based on cultural transmission need to consider the full set of hypotheses a learner could entertain and all

    Neck bands are a widely used marker in goose research. However, few studies have investigated a possible negative effect of this marker on survival. We tested the effect of neck bands on the survival of adult female greater snow geese (Chen caerulescens atlantica) by marking birds with either a neck band and a metal leg band or a leg band only on Bylot Island (Nunavut, formerly included in the Northwest Territories, Canada) from 1990 to 1996. Annual survival was estimated using leg-band recoveries in fall and winter and using neck-band sightings in spring and fall. Recapture rates were estimated using summer recaptures. Using recovery data, the selected model yielded a survival similar for the neck-banded and leg-banded only birds (S = 0.845 ?? 0.070 vs. S = 0.811 ?? 0.107). The hypothesis of equality of survival between the 2 groups was easily accepted under most constraints imposed on survival or recovery rates. However, failure to account for a different direct recovery rate for neck-banded birds would lead us to incorrectly conclude a possible negative effect of neck bands on survival. Using sighting data, mean annual survival of neck-banded birds was independently estimated at 0.833 ?? 0.057, a value very similar to that estimated with band-recovery analysis. Raw recapture rates during summer were significantly lower for neck-banded birds compared to those marked with leg bands only (4.6% vs. 12.1%), but in this analysis, survival, site fidelity, reproductive status, and recapture rates were confounded. We conclude that neck bands did not affect survival of greater snow geese, but could possibly affect other demographic traits such as breeding propensity and emigration.

    The number of new world records has decreased substantially in most athletic events in recent years. There has been enormous growth in participation at Masters events, and older athletes have been competing at the highest levels with much younger athletes. However, the progression of athletic performance over time has not been well investigated in Masters athletes. To determine whether older Masters athletes improved athletic performance over time, running and swimming times from 1975 to 2013 were collected biennially. The running event of 100 m was chosen specifically, as it is one of the most popular track and field events that would have attracted a large number of competitors. The middle distance of 400 m as well as 100 m freestyle swimming were also examined to determine whether the results in 100 m sprint event can be confirmed in other events. The improvements in fastest 100 m running times over time were not significant. However, all the Masters age-group records improved significantly over time. The slopes of improvements over the years were progressively greater at older age groups with the greatest progression observed at oldest age groups of 75-79 years examined. The general trends were similar for 400 m middle-distance running and 100 m freestyle swimming. While younger athletes' performance has stagnated, Masters athletes improved their athletic performance significantly and progressively over the years. The magnitude of improvements was greater in older age groups gradually closing the gap in athletic performance between younger and older participants. © The Author 2015.

    Reticuloendotheliosis (RE) in captive greater prairie chickens (GPC, Tympanuchus cupido pinnatus) and Attwater's prairie chickens (APC, Tympanuchus cupido attwateri) was first reported in 1998. RE is caused by avian reticuloendotheliosis virus (REV), an oncogenic and immunosuppressive retrovirus infecting multiple species of wild and domestic birds. During August 2004 through May 2006 a captive population of prairie chickens was affected simultaneously with a neoplastic condition and also avian pox, the latter being detected in 7.4% (2 of 27) of all birds submitted for histopathology. A survey for REV was conducted in order to examine its possible role in mortality observed primarily in juvenile and adult specimens of prairie chickens. The investigative procedures included postmortem examinations, histopathology, molecular detection, and virus isolation. In total, 57 Attwater's prairie chickens and two greater prairie chickens were included in the study. REV infection was diagnosed using virus isolation or polymerase chain reaction (PCR) or both in 59.5% (28 of 47) of blood samples and/or tumors from suspect birds. Lymphosarcomas were detected in the tissues of 37% (10 of 27) of the birds submitted for histopathology. Such lymphosarcomas suggestive of RE represented the most frequent morphologic diagnosis on histopathology among 27 separate submissions of naturally dead prairie chickens. Overall, REV was detected or RE diagnosed in 34 of 59 prairie chickens (57.62%). The average death age of all birds diagnosed with lymphosarcomas on histopathology was 2.2 yr, ranging from <1 to 4 yr. Although deaths associated with neoplasia occurred in males and females in equal proportions based on submissions, overall more males were diagnosed as REV infected or RE affected (16 males vs. 7 females, and 11 birds of undetermined gender). Reticuloendotheliosis virus was confirmed as a significant cause of mortality in captive prairie chickens.

  5. Environmental contaminant hazards to Attwater's greater prairie-chickens

    The Attwater's greater prairie-chicken (Tympanuchus cupido attwateri) was declared an endangered species in 1966 and exists only on the upper Gulf Coast prairie of southeast Texas. Since 1975, total numbers have declined from 2,240 to 1,456 in 1981 (Jurries 19679; W. Shifflett, Manager Attwater Prairie Chicken National Wildlife Refuge [APCNWR], personal communication).The total population of this prairie grouse is presently scattered in a norther, largely agricultural, but also urban-rangeland area of 6 counties that contained about 600 individuals in 1971, and a southern, largely rangeland, but also agricultural-urban area of 4 counties that contained about 860 individuals in 1981. During the present study, Attwater's prairie-chickens completely disappeared in Wharton and Waller counties in the northern area (W. Shifflett, personal communication).Prairie-chickens in the northern area frequent crops of rice, soybeans, peanuts, or corn; those in the southern area frequent sorghum or cotton that are planted on or near ancestral booming grounds. The use of pesticides in the agricultural areas may have contributed to the initial decline of prairie-chicken numbers. In 1927, several hundred prairie-chickens were found dead in and near a cotton field in Wharton County shortly after it had been treated with arsenic (Lehmann and Mauermann 1963). The remains of 5 prairie-chickens were found in sorghum and soybean fields in Refugio and Colorado counties between 1975 and 1977 (R. Haeber and W. Kessler, personal communication) but were too decomposed to be analyzed for evidence of pesticide exposure. Parathion formulations had been applied to the soybeans and near the sorghum. Other pesticide use on the areas was uncertain. The objective of this study was to ascertain pesticide hazards to Attwater's greater prairie-chickens.

    Three-dimensional pelvic images were reconstructed from multi-slice CT data of contemporary Japanese (males: 124; females: 104, 25-92 years old), and curvature analysis to examine sexual dimorphism was carried out in the great sciatic notch (GSN), the pubic arch and the greater pelvis in the images. Reconstructed pelvic CT images were visualized fairly well and anatomical landmarks were easily recognizable. When calculating the radii (curvature radii) of the best-fit circles for the spline curve lines set along the edges of the GSNs and of the pubic arches, sexes from these regions were correctly identified in 89.1% (males: 93.8%; females: 83.7%) and 94.7% (males: 97.3%; females: 91.8%) of cases, respectively, by setting an appropriate cut-off value. Furthermore, sexing was possible even in deeper regions of the GSN which are relatively resistant to postmortem damage. Curvature radii of the best-fit spheres of greater pelves showed no significant difference between sexes. However, curvature of the best-fit sphere for the left iliac fossa was significantly larger than that of the right one (p<10(-24)) in males, and the ratios were >1.0 in 88% of all male specimens analyzed. Meanwhile, no significant difference was observed among female samples. Although some left-sided dominancy has been reported in 2-dimensional measurements of the human pelvis, this 3-dimensional laterality in males was much more significant, and is a potential index of sex difference.

    Anorexia nervosa is a severe psychiatric disorder associated with reduced drive to eat. Altered taste-reward circuit white matter fiber organization in anorexia nervosa after recovery could indicate a biological marker that alters the normal motivation to eat. Women recovered from restricting-type anorexia (Recovered AN, n=24, age=30.3±8.1 years) and healthy controls (n=24, age=27.4±6.3 years) underwent diffusion weighted imaging of the brain. Probabilistic tractography analyses calculated brain white matter connectivity (streamlines) as an estimate of fiber connections in taste-reward-related white matter tracts, and microstructural integrity (fractional anisotropy, FA) was assessed using tract-based spatial statistics. Recovered AN showed significantly (range P<0.05–0.001, Bonferroni corrected) greater white matter connectivity between bilateral insula regions and ventral striatum, left insula and middle orbitofrontal cortex (OFC), and right insula projecting to gyrus rectus and medial OFC. Duration of illness predicted connectivity of tracts projecting from the insula to ventral striatum and OFC. Microstructural integrity was lower in Recovered AN in most insula white matter tracts, as was whole-brain FA in parts of the anterior corona radiata, external capsule, and cerebellum (P<0.05, family-wise error-corrected). This study indicates higher structural white matter connectivity, an estimate of fibers connections, in anorexia after recovery in tracts that connect taste-reward processing regions. Greater connectivity together with less-fiber integrity could indicate altered neural activity between those regions, which could interfere with normal food-reward circuit function. Correlations between connectivity and illness duration suggest that connectivity could be a marker for illness severity. Whether greater connectivity can predict prognosis of the disorder requires further study. PMID:26076832

    The island of Cyprus has a long historical record of earthquakes that have damaged pre-Roman to modern human settlements. Because the recurrent damaging earthquakes can have a significant economic and social impact on Cyprus, this project was initiated to develop a seismic-hazard assessment for a roughly 400 square kilometer area centered on Cyprus' capital and largest city, whose European name is Nicosia and whose local name is Lefkosia. In addition, geologic and seismotectonic evaluations for the project extended beyond the perimeter of the geologic map. Additional structural, stratigraphic, and paleontological data were collected island-wide as well as data from literature research throughout the eastern Mediterranean region, in order to accurately place the geology and seismic hazards of the Lefkosia area in a regional tectonic framework.

    The laws of the distribution of the snow cover on the mountains of the greater Caucasus are discussed. It is shown that an extremely unequal distribution of the snow cover is caused by the complex orography of this territory, the diversity of climatic conditions and by the difference in altitude. Regions of constant, variable and unstable snow cover are distinguished because of the clearly marked division into altitude layers, each of which is characterized by climatic differences in the nature of the snow accumulation.

    Epidemiological studies of mental health problems in the first years of life are few. This study aims to investigate infancy predictors of psychopathology in the second year of life. A random general population sample of 210 children from the Copenhagen Child Birth Cohort CCC 2000 was investigated by data from National Danish registers and data collected prospectively from birth in a general child health surveillance programme. Mental health outcome at 1(1/2) years was assessed by clinical and standardised measures including the Child Behavior Check List 1(1/2)-5 (CBCL 1(1/2)-5), Infant Toddler Symptom Check List (ITSCL), Checklist for Autism in Toddlers (CHAT), Bayley Scales of Infant Development (BSID II), Mannheim Eltern Interview (MEI), Parent Child Early Relational Assessment (PC ERA) and Parent Infant Relationship Global Assessment Scale (PIR-GAS), and disordered children were diagnosed according to the International Classification of Diseases (ICD-10) and Diagnostic Classification Zero to Three (DC: 0-3). Deviant language development in the first 10 months of life predicted the child having any disorder at 1(1/2) years, OR 3.3 (1.4-8.0). Neuro-developmental disorders were predicted by deviant neuro-cognitive functioning, OR 6.8 (2.2-21.4), deviant language development, OR 5.9 (1.9-18.7) and impaired social interaction and communication, OR 3.8 (1.3-11.4). Unwanted pregnancy and parents' negative expectations of the child recorded in the first months of the child's life were significant predictors of relationship disturbances at 1(1/2) years. Predictors of neuro-developmental disorders and parent-child relationship disturbances can be identified in the first 10 months of life in children from the general population.

    Knowledge about the presentation of psychopathology in preschool age and associated risk factors is fundamental to preventive intervention before schooling. To investigate the full spectrum of psychiatric diagnoses in general population children at the period of transition from preschool to school. A sample of 1585 children from the Copenhagen Child Cohort, CCC2000 aged 5-7 years was assessed using the Development and Well-Being Assessment (DAWBA) with diagnostic classification by experienced clinicians. Perinatal, sociodemographic and socio-economic data was obtained from Danish national registries. The prevalence of any ICD-10 psychiatric disorder was 5.7% (95%CI: 4.4-7.1). Pervasive developmental disorders (PDD) were found in 1.3% (95%CI: 0.8-1.8) and behavioural and hyperkinetic disorders were found in 1.5% (95%CI: 0.9-2.1) and 1.0% (95%CI: 0.4-1.6), respectively. Emotional disorders were found in 2.9% (95%CI: 1.9-40). More boys were diagnosed with PDD, behavioural disorders and tics. No gender differences were found in hyperactivity disorders (HD) and emotional disorders. Co-morbidity was frequent, in particular between HD and PDD, but also between HD and emotional disorder and behavioural disorder. Teenage mothers, single parents and low household income the first two years after the child's birth were associated with a three-to fourfold increased risk of psychiatric disorder in the child at age 5-7 years. The study results point to two "windows of opportunity" for prevention. In the earliest postnatal years, prevention should target families at socio-economic risk; and in the years before schooling, intervention should focus on children with symptoms of PDD, HD, and behavioural disorders.

    Permanent hair dye contains aromatic amines which are carcinogenic, and can cause allergic skin reactions. In the long term personal use of hair dye might therefore influence both morbidity and mortality. We tested the hypothesis that personal use of hair dye in women is associated with increased morbidity and mortality in the general population. We included 7,684 women from the Copenhagen City Heart Study with information on the use of personal hair dye. We assessed the risk of cancer, skin diseases, other morbidities, and mortality during a median follow-up of 27 years (range 0-37). The multivariable adjusted hazard ratio for malignant melanoma in women with versus without personal use of hair dye was 2.07 (95% confidence interval 1.25-3.42). There was no increased risk of other cancer types. For other skin diseases and other major causes of morbidity we found no differences between the two groups, except for a minor excess of digestive diseases and increased risk of Parkinson's disease among women using hair dye. Finally, we found no difference in all-cause mortality comparing women using personal hair dye or not. After correction for multiple comparisons, none of the results remained significant. However, in sensitivity analysis the excess risk of malignant melanoma remained increased with a hazard ratio of 2.58 (95%CI 1.33-5.03) among users of personal hair dye. Personal use of hair dye does not have major influences on morbidity and mortality. Our finding of a 2-fold risk of malignant melanoma in women using hair dye is hypothesis generating.

    Objective To examine whether elevated resting heart rate (RHR) is an independent risk factor for mortality or a mere marker of physical fitness (VO2Max). Methods This was a prospective cohort study: the Copenhagen Male Study, a longitudinal study of healthy middle-aged employed men. Subjects with sinus rhythm and without known cardiovascular disease or diabetes were included. RHR was assessed from a resting ECG at study visit in 1985–1986. VO2Max was determined by the Åstrand bicycle ergometer test in 1970–1971. Subjects were classified into categories according to level of RHR. Associations with mortality were studied in multivariate Cox models adjusted for physical fitness, leisure-time physical activity and conventional cardiovascular risk factors. Results 2798 subjects were followed for 16 years. 1082 deaths occurred. RHR was inversely related to physical fitness (p<0.001). Overall, increasing RHR was highly associated with mortality in a graded manner after adjusting for physical fitness, leisure-time physical activity and other cardiovascular risk factors. Compared to men with RHR ≤50, those with RHR >90 had an HR (95% CI) of 3.06 (1.97 to 4.75). With RHR as a continuous variable, risk of mortality increased with 16% (10–22) per 10 beats per minute (bpm). There was a borderline interaction with smoking (p=0.07); risk per 10 bpm increase in RHR was 20% (12–27) in smokers, and 14% (4–24) in non-smokers. Conclusions Elevated RHR is a risk factor for mortality independent of physical fitness, leisure-time physical activity and other major cardiovascular risk factors. PMID:23595657

    To evaluate the prediction of malignancy in women with pelvic masses using the Copenhagen Index (CPH-I) and Risk of Ovarian Malignancy Algorithm (ROMA). Three hundred eighty four women operated due to an ovarian mass were enrolled between January 2010 and June 2015. All patients had histopathological diagnosis, HE4 and CA125 measurement. CPH-I and ROMA were calculated and their performances compared in two distinct scenarios: 1) for the discrimination of benign ovarian disease from epithelial ovarian cancer (EOC), non-epithelial ovarian cancer, borderline ovarian tumors (BOT) and ovarian metastases, and 2) for the discrimination of benign disease from EOC. Receiver Operator Characteristics' Areas Under the Curves (AUC) were calculated for CPH-I and ROMA and compared. Of the 384 women, 224 presented a benign ovarian tumor, 32 BOT, 87 EOC, 26 non-epithelial ovarian cancer, and 15 had ovarian metastases. The best AUCs were obtained for the discrimination of EOC from benign tumors. CPH-I performed slightly better than ROMA, and both approached 89% sensitivity and 85% specificity. When all malignant tumors (EOC, BOT, ovarian metastases and non-epithelial ovarian cancer - entire cohort) were included, the performance of CPH-I and ROMA declined to nearly 72%, although the specificity remained close to 85%. CPH-I and ROMA performed similarly well for the discrimination of EOC from benign ovarian tumors. However, caution is necessary since, in practical situations, where all the histological possibilities for malignant ovarian tumors must be considered, the sensitivity of CPH-I and ROMA may not surpass 70%.

    We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and uses the latter to build a consistent and improved metallicity scale. Metallicities are calibrated on high-resolution spectroscopy and checked against four open clusters and a moving group, showing excellent consistency. The new temperature and metallicity scales provide a better match to theoretical isochrones, which are used for a Bayesian analysis of stellar ages. With respect to previous analyses, our stars are on average 100 K hotter and 0.1 dex more metal rich, which shift the peak of the metallicity distribution function around the solar value. From Strömgren photometry we are able to derive for the first time a proxy for [α/Fe] abundances, which enables us to perform a tentative dissection of the chemical thin and thick disc. We find evidence for the latter being composed of an old, mildly but systematically alpha-enhanced population that extends to super solar metallicities, in agreement with spectroscopic studies. Our revision offers the largest existing kinematically unbiased sample of the solar neighbourhood that contains full information on kinematics, metallicities, and ages and thus provides better constraints on the physical processes relevant in the build-up of the Milky Way disc, enabling a better understanding of the Sun in a Galactic context.

    Outside normal office hours, patients in Denmark with acute conditions are treated by the out-of-hours service connected to general practice and in the emergency rooms of hospitals. Little is known about the contact pattern of immigrants with these services. The purpose of this study was to compare the contact rates for immigrants (guest workers and refugees) and non-immigrants with out-of-hours service and emergency rooms and compare the results with the total number of contacts with general practice (out-of-hours service, daytime contacts) and emergency rooms. Data from 2,243,633 contacts in Copenhagen 1998 registered in the National Patient Registry and 112,733 visits to emergency units were merged with information about citizenship and place of birth in the Central Office of Civil Registration. The contacts were described by the average number of contacts per person at risk per year. The contact rates with the out-of-hours service were significantly lower for immigrant children than for non-immigrants, whereas the number of visits to emergency rooms did not show any differences. For both sexes aged 19-59, the contact rates for out-of-hours service and emergency rooms were higher for immigrants. The total number of contacts was 31-11% lower for children and those 60+ years of age and 4-20% higher for 19- to 59-year-old immigrants. Significant differences in the use of acute services by immigrants and non-immigrants were observed. Whether this is appropriate is questionable.

    To examine choroidal thickness in a population-based child cohort in relation to birth parameters. The Copenhagen Child Cohort 2000 Eye Study examined 1406 children aged 11 to 12 years using enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT), ocular biometry and measurement of height, weight, refraction, and self-reported pubertal development status. Birth parameters were obtained from the Danish Medical Birth Registry. The subfoveal choroid in low birth weight children (<2500 g, n = 51, mean 324 ± 76 μm) was thinner than in normal birth weight children (2500-4500 g, n = 1194, mean 361 ± 78 μm), the difference being -37 (CI95 -60 to -15) μm, P = 0.001 after adjusting for age, sex, height, Tanner stage by sex, axial length, anterior chamber depth, and spherical equivalent refractive error. The subfoveal choroid in high birth weight children (>4500 g, n = 48, mean 351 ± 63 μm) was comparable with normal birth weight children, P = 0.44. The subfoveal choroid was thinner in preterm children, however the difference was not significant (-18 [-37 to 2] μm, P = 0.08). Small for gestation children had thinner subfoveal choroid (-19 [-37 to -1] μm, P = 0.04) compared with appropriate for gestation children. Longer birth length was associated with a thicker subfoveal choroid (2 [1-4] μm/cm, P = 0.005). Macular choroidal thickness at 16 extrafoveal locations was measured in a subset of children and found to have the same associations with birth weight as the subfoveal choroidal thickness. In 11- to 12-year-old children, thinner choroids were associated with lower birth weight, lower birth length, and being small for the gestational age.

  19. Morbidity and Mortality in 7,684 Women According to Personal Hair Dye Use: The Copenhagen City Heart Study followed for 37 Years

    PubMed Central

    2016-01-01

    Background Permanent hair dye contains aromatic amines which are carcinogenic, and can cause allergic skin reactions. In the long term personal use of hair dye might therefore influence both morbidity and mortality. Objectives We tested the hypothesis that personal use of hair dye in women is associated with increased morbidity and mortality in the general population. Methods We included 7,684 women from the Copenhagen City Heart Study with information on the use of personal hair dye. We assessed the risk of cancer, skin diseases, other morbidities, and mortality during a median follow-up of 27 years (range 0–37). Results The multivariable adjusted hazard ratio for malignant melanoma in women with versus without personal use of hair dye was 2.07 (95% confidence interval 1.25–3.42). There was no increased risk of other cancer types. For other skin diseases and other major causes of morbidity we found no differences between the two groups, except for a minor excess of digestive diseases and increased risk of Parkinson’s disease among women using hair dye. Finally, we found no difference in all-cause mortality comparing women using personal hair dye or not. After correction for multiple comparisons, none of the results remained significant. However, in sensitivity analysis the excess risk of malignant melanoma remained increased with a hazard ratio of 2.58 (95%CI 1.33–5.03) among users of personal hair dye. Conclusions Personal use of hair dye does not have major influences on morbidity and mortality. Our finding of a 2-fold risk of malignant melanoma in women using hair dye is hypothesis generating.

    The Carlsberg Fault zone (CFZ) is a NNW-SSE striking structure close to the transition zone between the Danish Basin and the Baltic Shield. We examine the fault evolution by combining very-high-resolution onshore shear-wave seismic data, one conventional onshore seismic profile and marine reflection seismic profiles. The faulting geometry indicates a strong influence of Triassic subsidence and rifting in the Central European Basin System. Growth strata within the CFZ surrounding Höllviken Graben reveal syntectonic sedimentation in the Lower Triassic, indicating the opening to be a result of Triassic rifting. In the Upper Cretaceous growth faulting documents continued rifting. These findings contrast the Late Cretaceous to Paleogene inversion tectonics in neighboring structures, such as the Tornquist Zone. The high-resolution shear-wave seismic method was used to image faulting in Quaternary and Danian layers in the CFZ. The portable compact vibrator source ElViS III S8 was used to acquire a 1150 m long seismic section on the island Amager, south of Copenhagen. The shallow subsurface in the investigation area is dominated by Quaternary glacial till deposits in the upper 5-11 m and Danian limestone below. In the shear-wave profile, we imaged the uppermost 30 m of the western part of CFZ. The complex fault zone comprises normal block faults and one reverse block fault. The observed faults cut through the Danian as well as the Quaternary overburden. Hence, there are strong indicators for ongoing faulting, like mapped faulting in Quaternary sediments and ongoing subsidence of the eastern block of the CFZ as interpreted by other authors. The lack of earthquakes localized in the fault zone implies that either the frequency of occurring earthquakes is too small to be recorded in the observation time-span, or that the movement of the shallow sub-surface layers may be due to other sources than purely tectonic processes.

    Eosinophilia may represent an early paraclinical sign of malignant disease and a host anti-tumor effect. The association between eosinophilia and the development of solid tumors has never before been examined in an epidemiological setting. The aim of the present study was to investigate eosinophilia in routine blood samples as a potential biomarker of solid tumor development in a prospective design. From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 356 196 individuals with at least one differential cell count (DIFF) encompassing the eosinophil count during 2000-2007. From these, one DIFF was randomly chosen and categorized according to no (< 0.5 × 10(9)/l), mild (≥ 0.5-1.0 × 10(9)/l) or severe (≥ 1.0 × 10(9)/l) eosinophilia. From the Danish Civil Registration System and the Danish Cancer Registry we ascertained all-cause death and solid tumors within the first three years following the DIFF. Using multivariable logistic regression, odds ratios (OR) were calculated and adjusted for previous eosinophilia, sex, age, year, month, C-reactive protein, previous cancer and Charlson's Comorbidity Index. The risk of bladder cancer was increased with mild eosinophilia [OR 1.93 (CI 1.29-2.89), p = 0.0013]. No associations with eosinophilia were observed for the remaining solid cancers. We demonstrate that eosinophilia in routine blood samples associates with an increased risk of bladder cancer. Our data emphasize that additional preclinical studies are needed in order to shed further light on the role of eosinophils in carcinogenesis, where it is still unknown whether the cells contribute to tumor immune surveillance or neoplastic evolution.

  2. San Andreas Fault, California, M 5.5 or greater Earthquakes 1800-2000

    The San Andreas fault has been the most significant source of major California earthquakes since 1800. From 1812 to 1906 it generated four major earthquakes of M 7.2 or greater in two pairs on two major regions of the fault. A pair of major earthquakes occurred on the Central to Southern region, where the 1857 faulting overlapped the 1812 earthquake faulting. And a pair of major earthquakes occurred on the Northern region, where the 1906 faulting overlapped the 1838 earthquake faulting. The 1812 earthquake resulted from a rupture of up to about 200 km, from the region of Cajon Pass to as far as about 50 km west of Fort Tejon (Sieh and others, 1989). This rupture is the probable source of both the destructive 1812.12.8 "San Juan Capistrano" and the 1812.12.21 "Santa Barbara Channel" earthquakes. The 1838 earthquake's damage effects throughout the Bay area, from San Francisco to Santa Clara Valley and Monterey, were unequalled by any Bay area earthquake other than the 1906 event. The mainshock's effects, and numerous strong probable aftershocks in the San Juan Bautista vicinity in the following three years, suggest 1838 faulting from San Francisco to San Juan Bautista, and M about 7.4. The 630 km length of the San Andreas fault between San Francisco and Cajon Pass ruptured in the 1838 and 1857 earthquakes, except for about 75 km between Bitterwater and San Juan Bautista. The 1840-1841 probable aftershocks of the 1838 event occurred near San Juan Bautista, and the foreshocks and aftershocks of the 1857 event occurred near Bitterwater. In the Bitterwater area, strong earthquakes continued to occur until the 1885 earthquake of M 6.5. Near Parkfield, 40 to 70 km southeast of Bitterwater, M 5.5 or greater earthquakes have occurred from the 1870s to the 1960s. In the total Bitterwater to Parkfield zone bracketing the northern end of the 1857 rupture, the seismicity and moment release has decreased steadily since 1857, and has tended to migrate southeastward with time.

    Elbrus volcano (5642m), the largest Quaternary volcano in the European part of the Russia, is situated within the central part of Greater Caucasus mountain system at the watershed of Black and Caspian seas. Complex isotope-geochronological studies showed that the Elbrus volcano experienced long (approximately 200-250 thousands years) discrete evolution, with protracted periods of igneous quiescence (approximately 50 ka) between large-scale eruptions. The volcanic activity of Elbrus is subdivided into three phases: Middle-Neopleistocene (225-170 ka), Late Neopleistocene (110-70 ka), and Late Neopleistocene-Holocene (less than 35 ka). No eruptions presumably occurred during 'quiescence' periods, while the volcano was dormant or revealed only insignificant explosive eruptions and postmagmatic activity. Volcanic rocks of the Elbrus volcano are represented by biotite-hypersthene-plagioclase calc-alcaline dacites (65.2-70.4% SiO2, and 6.4-7.9% K2O+Na2O at 2.7-3.9% K2O). Petrogeochemical and isotope-geochemical signatures of Elbrus dacitic lavas (87Sr/86Sr - 0.70535-0.70636, Eps(Nd) from +0.8 to -2.3, 206Pb/204Pb - 18.631-18.671, 207Pb/204Pb - 15.649-15.660, and 208Pb/204Pb = 38.811-38.847) point to their mantle-crustal origin. It was found that hybrid parental magmas of the volcano were formed due to mixing and/or contamination of deep-seated mantle melts by Paleozoic upper crustal material of the Greater Caucasus. The temporal evolution of isotope characteristics for lavas of Elbrus volcano is well described by a Sr-Nd mixing hyperbole between mantle source of 'Common'-type and estimated average composition of the Paleozoic upper crust of the Greater Caucasus. It was shown that, with time, the proportions of mantle material in the parental magmas of Elbrus gently increased: from ~60% at the Middle-Neopleistocene phase of activity to ~80% at the Late Neopleistocene-Holocene phase, which indicates an increase of the activity of deep-seated source at decreasing input of

    Objectives To describe the prevalence of greater trochanteric pain syndrome (GTPS); to determine whether GTPS is associated with iliotibial band (ITB) tenderness, knee osteoarthritis (OA), body mass index (BMI), or low back pain (LBP); and to assess whether GTPS is associated with reduced hip internal rotation, physical activity, and mobility. Design Cross-sectional, population-based study. Setting Multicenter observational study. Participants Community-dwelling adults (N=3026) ages 50 to 79 years. Interventions Not applicable. Main Outcome Measures Greater trochanteric tenderness to palpation in subjects with complaints of hip pain and no signs of hip OA or generalized myofascial tenderness. Results The prevalence of unilateral and bilateral GTPS was 15.0% and 8.5% in women and 6.6% and 1.9% men. Odds ratio (OR) for women was 3.37 (95% confidence interval [CI], 2.67–4.25), but age and race were not significantly associated with GTPS. In a multivariate model, adjusting for age, sex, ITB tenderness, ipsilateral and contralateral knee OA, BMI, and LBP, ITB tenderness (OR=1.72; 95% CI, 1.34–2.19), knee OA ipsilaterally (OR=3.47; 95% CI, 2.72–4.42) and con-tralaterally (OR=1.74; 95% CI, 1.32–2.28), and LBP (OR=2.79; 95% CI, 2.22–3.50) were positively related to GTPS. In this complete model, BMI was not associated with GTPS (OR=1.10; 95% CI, 0.80–1.52 when comparing ≥ 30 with <25kg/m2). Hip internal rotation range of motion did not differ based on GTPS status. After multivariate adjustment, GTPS did not alter physical activity score, but bilateal GTPS was significantly associated with a higher 20-meter walk time and chair stand time. Conclusions The higher prevalence of GTPS in women and in adults with ITB pain or knee OA indicates that altered lower-limb biomechanics may be related to GTPS. Slower functional performance in those with GTPS suggests that the study of targeted rehabilitation may be useful. A longitudinal study will be necessary to identify

    Background The New Cooperative Medical Scheme (NCMS) for peasantries implemented in 2003 and the Urban Resident Basic Medical Insurance (URBMI) for the urban unemployed implemented in 2007 have many similarities. They both apply the financing mode of individual premiums plus government’s subsidies, and the voluntary enrollment. The Chinese government plans to integrate these two systems and build a unified basic medical insurance system for the unemployed in order to achieve the medical equity and increase the general health level. Thus, to analyze the main influencing factors of the enrollment of the urban unemployed and rural residents is very important for improving the system and securing the stability of the system during the transition. Methods The study uses data from the China Health and Nutrition Survey (CHNS) and adopts logistic regression models to test which factors influence the enrollment of the URBMI and the NCMS under the background of rather high enrollment rate of Chinese basic medical insurances and strong fiscal support of the Chinese government, especially whether health status or age influences enrollment of these two insurances greater. Results There is indeed some adverse selection in the URBMI and the NCMS. Whether the individual has chronic diseases have significant influence on enrollments of both the urban unemployed and rural residents, while whether the individual got ill in last four weeks just influences enrollments of the urban unemployed. Age influences enrollment greater than health status. The older the insured are, the larger the enrollment rates are. Conclusion Because of the active support for basic medical insurances of the Chinese government, the enrollment performance of the urban unemployed and rural residents has already changed. When implementing the new policy, the government should pay attention to the willingness to enroll in and the change of enrollment performance of the insured. Therefore, under the policy of

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105 000 lives. Fuelled by greater Tokyo's rich seismological record, but challenged by its magnificent complexity, our joint Japanese-US group carried out a new study of the capital's earthquake hazards. We used the prehistoric record of great earthquakes preserved by uplifted marine terraces and tsunami deposits (17 M???8 shocks in the past 7000 years), a newly digitized dataset of historical shaking (10 000 observations in the past 400 years), the dense modern seismic network (300 000 earthquakes in the past 30 years), and Japan's GeoNet array (150 GPS vectors in the past 10 years) to reinterpret the tectonic structure, identify active faults and their slip rates and estimate their earthquake frequency. We propose that a dislodged fragment of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath the Kanto plain on which Tokyo sits. We suggest that the Kanto fragment controls much of Tokyo's seismic behaviour for large earthquakes, including the damaging 1855 M???7.3 Ansei-Edo shock. On the basis of the frequency of earthquakes beneath greater Tokyo, events with magnitude and location similar to the M??? 7.3 Ansei-Edo event have a ca 20% likelihood in an average 30 year period. In contrast, our renewal (time-dependent) probability for the great M??? 7.9 plate boundary shocks such as struck in 1923 and 1703 is 0.5% for the next 30 years, with a time-averaged 30 year probability of ca 10%. The resulting net likelihood for severe shaking (ca 0.9g peak ground acceleration (PGA)) in Tokyo, Kawasaki and Yokohama for the next 30 years is ca 30%. The long historical record in Kanto also affords a rare opportunity to calculate the probability of shaking in an alternative manner exclusively from intensity observations. This approach permits robust estimates

    1. Contrary to the generally high level of natal philopatry (i.e. likelihood that individuals breed at their natal colony) found in first-breeding colonial birds, little is known of natal philopatry later in life. Most hypotheses advanced to explain natal philopatry are valid at all ages. However, for young and inexperienced birds, the benefits of natal philopatry may be counterbalanced by the costs of intraspecific competition at the natal colony making dispersal temporarily advantageous. In turn, experience may increase competitive ability and make natal philopatry advantageous again. 2. We evaluated this hypothesis on the large-scale dispersal of greater flamingos Phoenicopterus roseus breeding among three colonies comprising >85% of the Western Mediterranean metapopulation. The Camargue (France) and Fuente de Piedra (Spain) are large and saturated colonies while Molentargius (Sardinia) is a recent and growing colony. 3. We used a 20-year capture-mark-resighting dataset of 4900 flamingos ringed as chicks in Camargue and Fuente de Piedra and breeding at the three colonies. We assessed the effects of natal colony and breeding experience (first-time observed breeders versus confirmed experienced breeders) on dispersal using multistate capture-recapture models. Dispersal to an unobservable state accounted for temporary emigration. 4. Fidelity was higher at the natal colony (>84%) than elsewhere. Fidelity increased with experience in the two large colonies (Camargue and Fuente de Piedra) suggesting a large-scale experience-related despotic distribution. Breeding dispersal was significant (up to 61% and 52% for first-time breeders and experienced breeders, respectively) so that colony dynamics is affected by exchanges with other colonies. Except for Fuente-born breeders leaving Molentargius, dispersal to the natal colony was higher than to any other colonies. 5. Survival was not higher at the natal colony. Inexperienced birds likely had lower breeding success at the

    Recent surveys of medieval era chronicles provide calendar accurate information of years of unusual, extreme weather and climate events in areas surrounding the eastern Mediterranean, between the mid-A.D. 10th century and end of the 11th century. Put together, these documents show that the region was simultaneously afflicted by unprecedented sever and persistent droughts in Egypt's Nile Valley and by unusually cold and dry winters associated with crop failure and loss of pasture areas in present-day Iraq and Iran, and in historical Khurasan. We show that this documentary information is consistent with the annually dated Nile summer flood record as measured at the Cairo Nilometer site and within acceptable dating accuracies with much more coarsely resolved regional paleoclimate proxies. We furthermore note that the timing of these events coincided with the Oort Grand Solar Minimum that reached its peak between A.D. 1040 and 1080. Given the scientific evidence for the impact of solar minima on sea surface temperatures in the equatorial Pacific and how the latter affect the intensity of the African summer monsoon, we argue that the Oort Solar Minimum forced the frequent failure of the Nile summer floods resulting in dearth and famine in Egypt. Furthermore, the simultaneous cold and dry winters in the northern Near East are also consistent with the hypothesized solar minimum influence on the North Atlantic Oscillation and on the intensity of the Siberian High. This interpretation underscores the sensitivity of the climate system to variations in solar irradiance, particularly on multi-decadal time scales, to their role in regional processes, and their impact on human history and may help understand other rapid Mediterranean cooling events that occured during the Holocene.

    We characterize a plateau and proximal eastern regions, consisting of Thaumasia, Solis, and Syria Planae, in terms of chemistry, mineralogy, and mapped geology. We determine how such independent and complementary data bear upon the evolution of this region for mantle evolution models[1]. Three chemical provinces make up the Greater Thaumasia (GT) and are less obscured by unconsolidated layers of globally-derived < 40 μm-size sediments [Fig. 5][2]. This enables complementary insight from Visible/Near/Thermal-Infrared data[3]. Depleted H and enriched Si relative to their respective global averages[4] define region 70 to the East, with the southeastern parts of GT exposing many non-volcanic rocks dating to middle-late Noachian[5]. On the West, region 90 marks K and Th depletion. Region 75 is an overlap of regions 70 and 90. GT exposes Hesperian-aged units of mostly volcanic origin in the NW, with region 90 localized in Syria Planum and 75 in Solis Planum. Comparing elemental mass fractions derived from Mars Odyssey GRS of GT sub-regions to the rest of Mars (ROM), confirms Ca depletion in region 70. H2O depletion relative to ROM gets enhanced eastward to 70. Intriguingly, the intra-regional variation in Ca, as observed by the comparison with ROM, highlights its enrichment in 90 and 75. This may present an elemental signature supporting the detection of High-Ca Pyroxene (HCP) rocks by Rogers et al. [2014]. In detail, this convergence between regions 75 and 90, with the TES compositional class 8[3], indicate a possibility of HCP-rich volcanism. The enrichment of Si accompanied by H and Th depletion, across the Noachian-Hesperian transition in GT, diverges from mantle evolution models[1]. References [1] Balta, J. B. & McSween, H.

    2013-01-01

    Emotional empathy and prosocial behavior were assessed in older, middle-aged, and young adults. Participants watched two films depicting individuals in need, one uplifting and the other distressing. Physiological responses were monitored during the films and participants rated their levels of emotional empathy following each film. As a measure of prosocial behavior, participants were given an additional payment they could contribute to charities supporting the individuals in the films. Age-related linear increases were found for both emotional empathy (self-reported empathic concern and cardiac and electrodermal responding) and prosocial behavior (size of contribution) across both films and in self-reported personal distress to the distressing film. Empathic concern and cardiac reactivity to both films, along with personal distress to the distressing film only, were associated with greater prosocial behavior. Empathic concern partially mediated the age-related differences in prosocial behavior. Results are discussed in terms of our understanding both of adult development and of the nature of these vital aspects of human emotion. PMID:21859198

    Emotional empathy and prosocial behavior were assessed in older, middle-aged, and young adults. Participants watched two films depicting individuals in need, one uplifting and the other distressing. Physiological responses were monitored during the films, and participants rated their levels of emotional empathy following each film. As a measure of prosocial behavior, participants were given an additional payment they could contribute to charities supporting the individuals in the films. Age-related linear increases were found for both emotional empathy (self-reported empathic concern and cardiac and electrodermal responding) and prosocial behavior (size of contribution) across both films and in self-reported personal distress to the distressing film. Empathic concern and cardiac reactivity to both films, along with personal distress to the distressing film only, were associated with greater prosocial behavior. Empathic concern partially mediated the age-related differences in prosocial behavior.

    In 1985, Public Law 99-240 (Low-Level Radioactive Waste Policy Amendments Act of 1985) made the Department of Energy (DOE) responsible for the disposal of greater-than-Class C low-level radioactive waste (GTCC LLW). DOE strategies for storage and disposal of GTCC LLW required characterization of volumes, radionuclide activities, and waste forms. Data from existing literature, disposal records, and original research were used to estimate characteristics, project volumes, and determine radionuclide activities to the years 2035 and 2055. Twenty-year life extensions for 70% of the operating nuclear reactors were assumed to calculate the GTCC LLW available in 2055. The following categories of GTCC LLW were addressed: Nuclear Utilities Waste; Potential Sealed Sources GTCC LLW; DOE-Held Potential GTCC LLW; and Other Generator Waste. It was determined that the largest volume of these wastes, approximately 57%, is generated by nuclear utilities. The Other Generator Waste category contributes approximately 10% of the total GTCC LLW volume projected to the year 2035. DOE-Held Potential GTCC LLW accounts for nearly 33% of all waste projected to the year 2035. Potential Sealed Sources GTCC LLW is less than 0.2% of the total projected volume. The base case total projected volume of GTCC LLW for all categories was 3,250 cubic meters. This was substantially less than previous estimates.
