    Del Norte Regional Recycling and Transfer Station is owned by the city of Oxnard, California and operated by BLT Enterprises, Inc. The Del Norte facility--located in southwestern Ventura County about an hour northwest of Los Angeles--processes polyethylene terephthalate (PET) and high-density polyethylene (HDPE) plastic containers, aluminum, steel, glass, old corrugated containers (OCC), newspapers, computer printout paper, white and colored ledger paper, coated book, supermix paper, telephone books, and old magazines. According to the company, there has been virtually no community opposition to the site. The facility has few neighbors, and those are agricultural. To keep the community relationship strong, the facility`s design and location all but eliminated odor and noise complaints. The building was designed against the prevailing wind pattern, and BLT processes odorous material fast. A misting system installed for dust suppression also can be used with a solution for odor control should the need arise.

  8. Modeling visibility in the Paso del Norte (PDN) Region

    NASA Astrophysics Data System (ADS)

    Medina Calderon, Richard

    Poor visibility is a subject of growing public concern throughout the U.S, and an active area of research. Its societal impacts on air quality, aviation transport and traffic are significant. Aerosols play a fundamental role in the attenuation of solar radiation, and also affect visibility. The scattering and extinction coefficients of aerosol particles in the Paso del Norte Region have been calculated using the T- matrix model in conjunction with a laser particle counter. Inter-comparison of the model's results of the scattering and absorption coefficients against the corresponding data from a Photoacustic extinctiometer instrument (which measures in-situ absorption and scattering coefficients of aerosol particles) shows excellent agreement. In addition, the volume-weighted method is used to determine the composite index of refraction which is representative of the aerosols for the Paso del Norte Region to obtain information of the type of aerosol particles present in the Region. The Single Scattering Albedo has also been retrieved using this methodology to obtain further insight into the type of aerosols present on a given day. Finally, the Koschmieder equation has been used to calculate the visual range or visibility, and was correlated with the PM2.5 and PM10 particle concentration present in the Region. Our methodology will allow a better understanding of the size and type of aerosol particles that are most detrimental to the visibility for the Paso Del Norte Region.

    Herbalists in Baja California Norte, Mexico, were interviewed to determine the ailments and diseases most frequently treated with 22 commonly used medicinal plants. Those diseases which were most frequently mentioned by the herbalists provided the focus for initial assessments. The phytochemistry of the medicinal plants was determined from published research, and the likelihood of successful treatment of diseases was assessed by determining the known pharmacological actions of the plant constituents. Most of the plants contained substances which had recognized pharmacological effects in the treatment of the diseases being treated by the herbalists.

  13. Classification of Nortes in the Gulf of Mexico derived from wave energy maps

    NASA Astrophysics Data System (ADS)

    Appendini, C. M.; Hernández-Lasheras, J.

    2016-02-01

    Extreme wave climate in the Gulf of Mexico is determined by tropical cyclones and winds from the Central American Cold Surges, locally referred to as Nortes. While hurricanes can have catastrophic effects, extreme waves and storm surge from Nortes occur several times a year, and thus have greater impacts on human activities along the Mexican coast of the Gulf of Mexico. Despite the constant impacts from Nortes, there is no available classification that relates their characteristics (e.g. pressure gradients, wind speed), to the associated coastal impacts. This work presents a first approximation to characterize and classify Nortes, which is based on the assumption that the derived wave energy synthetizes information (i.e. wind intensity, direction and duration) of individual Norte events as they pass through the Gulf of Mexico. First, we developed an index to identify Nortes based on surface pressure differences of two locations. To validate the methodology we compared the events identified with other studies and available Nortes logs. Afterwards, we detected Nortes from the 1986/1987, 2008/2009 and 2009/2010 seasons and used their corresponding wind fields to derive the wave energy maps using a numerical wave model. We used the energy maps to classify the events into groups using manual (visual) and automatic classifications (principal component analysis and k-means). The manual classification identified 3 types of Nortes and the automatic classification identified 5, although 3 of them had a high degree of similarity. The principal component analysis indicated that all events have similar characteristics, as few components are necessary to explain almost all of the variance. The classification from the k-means indicated that 81% of analyzed Nortes affect the southeastern Gulf of Mexico, while a smaller percentage affects the northern Gulf of Mexico and even less affect the western Caribbean.

  14. Ethnobotanical treatments of diabetes in Baja California Norte.

    Winkelman, M

    1989-06-01

    This paper provides a brief review of the current biomedical knowledge on some of the medicinal plants used in the treatment of diabetes in Baja California Norte. In general there is very little biochemical knowledge of the specific modes of action in the treatment of diabetes, but most of the plants have been found to contain substances (e.g., glucosides, alkaloids) frequently implicated as having anti-diabetic effects. Furthermore, clinical studies with animals indicate that most of these plants do have hypoglycemic properties. This paper calls attention to the need for further biochemical investigations into the plant constituents and invites collaboration in the development of clinical field studies to assess the efficacy of herbalists' use of medicinal plants in the treatment of diabetes in Baja California Norte or other U.S.-Mexico border areas. Such research can make an important contribution to the World Health Organization's plan of "Health for All by the Year 2000" through establishing a scientific basis for traditional medicine.

  15. Weathering profiles in granites, Sierra Norte (Córdoba, Argentina)

    NASA Astrophysics Data System (ADS)

    Kirschbaum, Alicia; Martínez, Estela; Pettinari, Gisela; Herrero, Silvana

    2005-09-01

    Two weathering profiles evolved on peneplain-related granites in Sierra Norte, Córdoba province, were examined. Several weathering levels, of no more than 2 m thickness, were studied in these profiles. They had developed from similar parent rock, which had been exposed to hydrothermal processes of varying intensity. Fracturing is the most notable feature produced by weathering; iron oxides and silica subsequently filled these fractures, conferring a breccia-like character to the rock. The clay minerals are predominantly illitic, reflecting the mineral composition of the protolith. Smaller amounts of interstratified I/S RO type are also present, as well as scarce caolinite+chlorite that originated from the weathering of feldspar and biotite, respectively. The geochemical parameters define the weathering as incipient, in contrast to the geomorphological characteristics of Sierra Norte, which point to a long weathering history. This apparent incompatibility could be due to the probable erosion of the more weathered levels of the ancient peneplains, of which only a few relicts remain. Similar processes have been described at different sites in the Sierras Pampeanas. Reconstruction and dating of the paleosurfaces will make it possible to set time boundaries on the weathering processes studied and adjust the paleographic and paleoclimatic interpretations of this great South American region.

  17. Ozone studies in the Paso del Norte region

    NASA Astrophysics Data System (ADS)

    Becerra-Davila, Fernando

    The Paso del Norte region forms the largest contiguous bi-national conglomerate on the US-Mexico border. With a combined population of around 2 million inhabitants, the Paso del Norte region is isolated, more than 500 km away from the nearest urban area of comparable size, thus making it an ideal location for air quality studies of an isolated urban environment. The meteorological conditions leading to a high ozone episode in this region, such as the historical ozone episode of June 2006, are analyzed. It is well known that stagnation and minimal winds, high temperatures, and pressure ridges over the region are conducive to high ozone episodes. In addition, the planetary boundary height is studied to understand its impact on high ozone episodes. Several studies report that ground level ozone non-attainment regulations could be caused not only by local emissions, but also by atmospheric transport. In this work the atmospheric advection of pollutants into the region is analyzed using HYSPLIT backward trajectories. Furthermore, a novel backward trajectory clustering technique is implemented for the summer of 2006. The "ozone weekend effect" (OWE) is a phenomenon by which in some geographical regions ambient ozone concentrations tend to be higher on weekends than on weekdays, despite the lower emissions of ozone precursors during those days. The observed local OWE has never previously been studied in terms of the photolysis rates of four of the main ozone precursors. In this research a novel method that allows the calculation of actinic fluxes, photolysis frequencies and photolysis rates with a high degree of accuracy and reliability has been developed. This method utilizes a combination of the experimental data available for this region in conjunction with a radiative transfer model (TUV model). Three weekend-weekday cases during summers 2006, 2009 and 2010 are studied in this work. In this research, the photolysis impact on the local OWE is studied. The results

    The results of VOC determinations of ambient air samples collected at surface air quality monitoring sites and near sources of interest on the US and Mexican side of the border during six weeks of the 1996 Paso del Norte Ozone Study are reported. Carbonyl samples were collected on DNPH impregnated cartridges at three surface sites and analyzed by HPLC to quantify 13, C-1 to C-8 species. Whole air samples were collected in electro-polished stainless steel canisters which were returned to laboratory for determination of C-2 to C-10+ hydrocarbons by cryogenic preconcentration capillary gas chromatography with flame ionization detection (gc-fid). Several sources were sampled: rush hour traffic, propane-powered bus exhaust, automobile paint shop emissions, propane fuel, petroleum refinery, and industrial manufacturing site. Spatial and temporal characteristics of VOC species concentrations and compositions are presented. Overall surface TNMOC values ranged from 0.1 to 3.4 ppmC with the highest concentrations recorded in the morning at three vehicle-dominated sites, two in Cuidad Juarez and one in downtown El Paso. Toluene in El Paso samples and propane, which is used as a cooking and transportation fuel in Cuidad Juarez, were the most abundant hydrocarbons.

  1. Extreme waves from Nortes and climate change in the Gulf of Mexico

    2017-04-01

    Extreme ocean waves in the Gulf of Mexico are a result from the incidence of tropical cyclones and anticyclone systems known as Nortes. While the waves derived from tropical cyclones have devastating consequences but a low probability of occurrence, Nortes are a frequent phenomenon producing disruptions of maritime activities during autumn/winter months. In this study we present an assessment of the waves generated by Nortes and the effects of a warming climate. To do so, we first developed a methodology to identify Norte events and classify them according to their effect over the sea state. A new index is proposed to identify events, which was used to identify events in the present and future climates. A third generation wave model was run for each of the events identified in the CFSR reanalysis and the CMIP5 model CNRM-M5 under the RCP 8.5 scenario. Nortes were classified into 5 types, using both principal component analysis and a cluster analysis by k-means over the computed wave power of the individual events. An assessment of the effect of climate change was performed over the different Norte types, which indicated that climate change will result in less frequent events of higher intensity and more frequent mild events. This may provide a relief for coastal and marine operations, in relation to downtimes due to extreme wave conditions, so that the operational design of maritime structures could consider a lower occurrence of extreme events as a result of Nortes. While the results are not conclusive due to the uncertainty imposed by Global Circulation Models, this study provides the methodology to perform the assessment on other models to reduce uncertainty.

    Ambient air VOC samples were collected at surface air quality monitoring sites, near sources of interest, and aloft on the US and Mexican side of the border during a six week period of the 1996 Paso del Norte Ozone Study. On nine intensive operations (IOP) days, when high ozone concentrations were forecast, five 2-hr samples were collected at five IOP sites, three on the US side and two on the Mexican side. Six special survey sites on the US side and two on the Mexican side were sampled to characterize up-wind, down-wind and other emissions. In Ciudad Juarez, rush hour traffic, propane-powered bus exhaust, automobile paint shop emissions, propane and butane fuels, and an industrial manufacturing site were sampled. Carbonyl samples were collected at three surface sites. Carbonyl and canister grab samples were also collected during aircraft and hot air balloon flights. Most of the hydrocarbon samples were collected in electro-polished stainless steel canisters which were returned to laboratories for determination of C-2 to C-10+ hydrocarbons by cryogenic preconcentration GC-FID. The carbonyl samples were collected on DNPH impregnated C-18 Sep-Pak cartridges and analyzed by HPLC to quantify 13, C-1 to C-8 species. This paper presents the spatial and temporal characteristics of VOC species concentrations and compositions to examine the differences and similarities of the various locations and time periods. Overall surface TNMOC values ranged from 0.1 to 3.4 ppmC with the highest concentrations being recorded in the morning at three vehicle-dominated sites, two in Ciudad Juarez and one in downtown El Paso. Toluene in El Paso samples and propane, which is used as a cooking and transportation fuel in Ciudad Juarez, were the most abundant hydrocarbons. The most abundant carbonyls were acetaldehyde and acetone.

  3. Quaternary deformation around the Palo Negro area, Pampa Norte, Argentina

    NASA Astrophysics Data System (ADS)

    Brunetto, E.; Iriondo, M.; Zamboni, L.; Gottardi, G.

    2010-04-01

    The Pampa Norte region is a great plain characterized by low slopes and accumulation of hundreds of meters of thick loose sediments. A high morphostructure denominated San Guillermo block stands out in the central plain, the Tostado-Selva scarp forming its western boundary. It is located in an intraplate setting characterized by low tectonic activity. However recent uplift can be inferred by means of terrain analysis and the sedimentology of the Palo Negro Fm. Pond deposits (Palo Negro Fm.) observed in the scarp suggest topographic inversion during the Late Quaternary in the Palo Negro area. The morphology indicates that the deformation was widely distributed, forming a gentle (ca. 5 m amplitude and 13 km wavelength) asymmetric fold. Low sinuosity lineaments located in the base of the scarp, coincident with knick points in the topographic profile, can be interpreted as the projection of tip-lines by high-angle fault-propagation. This geometry is compatible with reverse kinematics on blind faults. A deformation style with reactivation of pre-existing faults is consistent with structural observations. Seismic reflectors suggest the presence of Cretaceous high-angle normal faults, and the orientation of lineaments is similar to the orientation of the graben systems and transverse accommodation zones originated during the opening of the South Atlantic Ocean. One OSL dating of 67.4 ± 5.1 kyr B.P (from Palo Negro Fm. supposed as deposited on a flat plain floor) and a height difference of 9.5 m measured in the Tostado-Selva scarp account for an averaged uplift rate of 0.14 mm/year.

    Background Pulmonary tuberculosis (PTB) and paragonimiasis remain as health problems in certain areas in the Philippines. Both share similar clinical manifestations, which include chronic productive cough, hemoptysis, dyspnea, fever, weight loss, and night sweats. This study aimed to determine the prevalence of PTB, paragonimiasis, and co-infections in Zamboanga del Norte, Philippines. Methods This study was conducted in selected villages in two municipalities in Zamboanga del Norte. Patients with chronic cough were interviewed, examined, and requested to submit two sputum samples which were processed using Ziehl–Neelsen method to detect acid-fast bacilli (AFB), and NaOH concentration technique for the detection of Paragonimus ova. Results A total of 836 patients submitted sputum samples for examination. Prevalence was 6.7% (2.5–12.7%) for paragonimiasis and 1.9% (0.9–6.3%) for PTB. Co-infection rate was 0.3%, with two identified cases. Positivity rates for males and females were 9.6 and 5.8% for paragonimiasis and 3.4 and 1.2% for PTB. Conclusion Pulmonary tuberculosis and paragonimiasis are co-endemic in Zamboanga del Norte, suggesting the need to integrate surveillance and control efforts. Strengthening local health systems through collaboration between different sectors is recommended for effective disease control. Development of more sensitive diagnostic tests is important for more accurate disease surveillance. PMID:24601907

    The Echaurren Norte Glacier (33°34'S 70°07'W) is a small mountain glacier located at the upper Maipo basin, approximately 80 km to Santiago de Chile. The glacier has the longest surface mass balance record in South America (1975 to 2016). The measurements are carried out by DGA (water directory of Chile) using the direct glaciological method. The surface mass balance show continuous negative values, but exceptional positive mass balances were identified during ENSO periods. The aim of our study is complement the in-situ observations on Echaurren Norte Glacier with the geodetic mass balance measurements for the period 1955 to 2015. Our database comprises digital elevation models (DEM) from historical cartography based on aerial photographs (1955), SRTM (2000) and Lidar data. In addition, we mapped changes in glacier extent using aerial photography and multi-mission satellite data. TanDEM-X (2012-2015) and SRTM data will be used to investigate surrounding glaciers that have not such extensive and detailed coverage as Echaurren Norte Glacier. The aerial photographs from 1955 were scanned from the original negative using a photogrammetric scanner and processed on a digital photogrammetric workstation (DPW) and georeferenced with the aid of GCPs derived from the Lidar dataset. The TanDEM-X data was processed using differential interferometry using SRTM C-band DEM as reference. Differences resulting from X- and C-band penetration are considered comparing X- and C-band SRTM data. All DEMs were laterally and vertically co-registered to each other. Error assessment was done over stable ground. Our preliminary results indicate an elevation change of -42.2 m ± 4 m (1955-2015) for Echaurren Norte Glacier. The estimated averaged annual mass balance is -0.59 m water equivalent for the period 1955-2015 using a density of 0.85 kg/cm3 for volume to mass conversion. Significant changes of the surface cover were identified, with a considerable increase of the debris cover, in

    Women who resided on the El Paso, Texas/Juarez, Mexico border (the Paso del Norte region) were surveyed to determine the barriers and facilitators to receiving early and adequate prenatal care. Postpartum interviews and medical chart abstractions were conducted among 493 Hispanic women. Primary facilitators were all factors that made prenatal care services more accessible to women and a priority among other issues competing for time and resources. The factors reported by these women as barriers to timely entry and sustaining enrollment in prenatal care were related to the availability of social support networks and affiliation with the Mexican/Hispanic culture (acculturation).

    This paper summarizes the results of analyses of meteorological and air quality data for the 1996 Paso del Norte Ozone Study. The purpose of these data analyses was to develop an understanding of the significant chemical and physical processes which lead to high concentrations of ozone in the Paso del Norte study region which includes El Paso, TX; Sunland Park, NM; and Juarez, Mexico. This analysis has shown that the high ozone concentrations are a result of slow convective boundary layer growth, reduced convective boundary layer depth, light surface winds, and high morning surface ozone precursor concentrations. Overlying meteorological conditions observed during high ozone episodes include an upstream aloft high pressure system, aloft warming, and weak surface pressure gradients. The analysis has also shown that aloft carryover of ozone and ozone precursors does not significantly contribute to the surface ozone concentration. Furthermore, hydrocarbon and NO{sub x} data, although spatially limited, show that the system is most often NO{sub x} rather than VOC limited.

    Leprosy is a public health problem in Brazil where 31,044 new cases were detected in 2013. Rio Grande do Norte is a small Brazilian state with a rate of leprosy lower than other areas in the same region, for unknown reasons. We present here a review based on the analysis of a database of registered leprosy cases in Rio Grande do Norte state, comparing leprosy's geographic distribution among municipalities with local socio-economic and public health indicators and with historical documents about human migration in this Brazilian region. The current distribution of leprosy in Rio Grande do Norte did not show correlation with socio-economic or public health indicators at the municipal level, but it appears related to economically emerging municipalities 100 years ago, with spread facilitated by railroads and train stations. Drought-related migratory movements which occurred from this state to leprosy endemic areas within the same period may be involved in the introduction of leprosy and with its present distribution within Rio Grande do Norte. Leprosy may disseminate slowly, over many decades in certain circumstances, such as in small cities with few cases. This is a very unusual situation currently and a unique opportunity for epidemiologic studies of leprosy as an emerging disease.

    The Del Norte County Pesticide Storage Area is located northwest of Cresent City, California. The site soils and ground water were contaminated with a myriad of pesticides and herbicides. The data also indicated an elevated concentration of chromium was present on-site and off-site; however, it does not appear to be related to the activities involving the use of the site as a pesticide storage area. The site was included on the National Priorities List in 1983. The storage area operated from 1970 until 1981, accepting containers from local agricultural and forestry-related industries. The intended use of the site was as an interim or emergency storage area for pesticide containers which had been triple rinsed and punctured prior to coming to the site. There were 9 private wells monitored within 0.50 miles of the site and the results indicated these wells were not contaminated by site contaminants. This site is of public health concern because of the potential for exposure to pesticides, herbicides, and chromium at concentrations of health concern.

    Background The Philippines is one of the developing countries highly affected by rabies. Dog vaccination campaigns implemented through collaborative effort between the government and NGOs have played an important role in successfully reducing the burden of disease within the country. Nevertheless, rabies vaccination of the domestic animal population requires continuous commitment not only from governments and NGOs, but also from local communities that are directly affected by such efforts. To create such long-term sustained programs, the introduction of affordable dog vaccination and registration fees is essential and has been shown to be an important strategy in Bohol, Philippines. The aim of this study, therefore, was to estimate the average amount of money that individuals were willing to pay for dog vaccination and registration in Ilocos Norte, Philippines. This study also investigated some of the determinants of individuals’ willingness to pay (WTP). Methods A cross-sectional questionnaire was administered to 300 households in 17 municipalities (out of a total of 21) selected through a multi-stage cluster survey technique. At the time of the survey, Ilocos Norte had a population of approximately 568,017 and was predominantly rural. The Contingent Valuation Method was used to elicit WTP for dog rabies vaccination and registration. A ‘bidding game’ elicitation strategy that aims to find the maximum amount of money individuals were willing to pay was also employed. Data were collected using paper-based questionnaires. Linear regression was used to examine factors influencing participants’ WTP for dog rabies vaccination and registration. Key Results On average, Ilocos Norte residents were willing to pay 69.65 Philippine Pesos (PHP) (equivalent to 1.67 USD in 2012) for dog vaccination and 29.13PHP (0.70 USD) for dog registration. Eighty-six per cent of respondents were willing to pay the stated amount to vaccinate each of their dogs, annually. This study

    The purpose of this project is to use geographic information system (GIS) and remote sensing methods to investigate the paleohydrology of the Paso del Norte region during the latest pluvial event. During the research I gathered the best available geologic and hydrographic data sets and integrated these data within a GIS in order to create a digital paleohydrologic database for the region. In particular, I used the GIS to reconstruct the hydrography (i.e. streams, lakes, and watershed boundaries) that existed as a results of increased precipitation and a decrease in temperature in the recent geologic past. The existence of the pluvial lakes had an impact on ground-water and surface-water flow systems in this region. The results of my research are presented as two papers ready for peer-review publication submission and a third paper that is a previously published work. (1) Using GIS and Remote Sensing to Reconstruct Late Quaternary and Early Holocene Paleo-Hydrography Using Climate Data and Modern Topography---an Example from the Southwestern US. This paper describes the methods used to create a paleo-hydrography system for the Paso del Norte region, and the development of a water-balance equation that estimates the inputs and outputs of this system. (2) Estimating Water-Balance Equation for Playas in the Tularosa Basin of Southern New Mexico. This paper describes the calibration and testing of the GIS model presented in the first paper. Before it can be applied to paleohydrologic systems, it must be shown to reasonably approximate playa systems in the region under current conditions. Water balances were calculated for several playas and their associated drainages.

    Pedologic photointerpretative criteria adapted to LANDSAT orbital imagery were used: drainage (pattern, integration degree, density and uniformity degree); relief (pattern, dissection degree and crest lines); photographic texture, photographic tonnality, and the land use (type, glebas size and intensity of use). The performance of the imagery as an auxiliar tool in the soil survey processes, at Rio Grande do Norte State was evaluated. The drainage and relief elements were easily extracted from the imagery and also ones that provided the greatest deductive possibility about pedologic boundaries. Other analyzed criteria were considered only auxiliaries, corroborating some soil limits in the evidences convergence phase. The principal pedologic dominions of the 30,000 sq km are covered by the same LANDSAT image (WRS 359/16) were delimited with good precision: (1) fluvial plains, beaches, dunes and coastal mangroves; (2) North Coast line Plateau; (3) Acu Sandstone Zone; (4) residual plateaus of the Tertiary; and (6) plains of the embasement.

    The Guadalupian rocks of the northern Del Norte Mountains were deposited in a foreland basin between land of the Marathon orogen and a carbonate shoal established on the geanticline separating the foreland basin from the Delaware basin. Deposition was alternately influenced by coarse clastic input from the orogen and carbonate shoal, which interrupted shallow basinal siltstone depletion. Relatively deeper-water deposition is characterized by carbonate input from the shoal, and relatively shallow-water deposition is characterized by sandstone input from the orogen. Deposition was in five general transgressive-regressive packages that include (1) the Road Canyon Formation and the first siltstone member and first sandstone member of the Word Formation, (2) the second siltstone member, Appel Ranch Member, and limy sandy siltstone member of the Word Formation, (3) the Vidrio Formation, (4) the lower and part of the middle members of the Altuda Formation, and (5) part of the middle and upper members of the Altuda Formation.

    β(S) haplotypes were studied in 47 non-related patients with sickle-cell anemia from the state of Rio Grande do Norte, Brazil. Molecular analysis was conducted by PCR/RFLP using restriction endonucleases XmnI, HindIII, HincII and HinfI to analyze six polymorphic sites from the beta cluster. Twenty-seven patients (57.5%) were identified with genotype CAR/CAR, 9 (19.1%) CAR/BEN, 6 (12.8%) CAR/CAM, 1 (2.1%) BEN/BEN, 2 (4.3%) CAR/Atp, 1 (2.1%) BEN/Atp and 1 (2.1%) with genotype Atp/Atp. The greater frequency of Cameroon haplotypes compared to other Brazilian states suggests the existence of a peculiarity of African origin in the state of Rio Grande do Norte.

    The 1996 Paso del Norte Ozone Study and subsequent data analyses were implemented to develop an understanding of the chemical and physical processes which lead to high concentrations of ozone in the Paso del Norte study area which includes El Paso County, Texas, Sunland Park, New Mexico, and Ciudad Juárez, Mexico. Both the data and data analysis results are being used to support photochemical grid modeling. El Paso County and Sunland Park fail to meet the National Ambient Air Quality Standard (NAAQS) for ozone, and neighboring Ciudad Juárez fails to meet the Mexican ambient standard for ozone. This paper summarizes the measurement campaigns of the 1996 Paso del Norte Ozone Study and the findings and conclusions that arose from subsequent data analyses. Data analyses showed that high ozone concentrations resulted from a combination of conditions, including high surface temperatures, strong sunlight with few clouds, light surface winds and high concentrations of ozone precursors at ground level in the morning, and slow convective boundary layer (CBL) growth. Synoptic-scale meteorological conditions observed during high ozone episodes included an aloft high-pressure system and aloft warming. Aloft carryover of ozone and ozone precursors did not significantly contribute to high concentrations of ozone at the surface.

    As canine rabies control in Africa and Asia transitions from research-led proof-of-concept studies to government-led programs for elimination, experience and evidence of their impact and costs must be shared for the benefit of future programs. The Ilocos Norte Communities against Rabies Exposure project was implemented in April 2012 by the provincial veterinary and health offices and supported by many other partners. It delivered a comprehensive dog vaccination program and increased awareness of the need for postexposure prophylaxis (PEP), aiming to eliminate human and animal rabies cases from Ilocos Norte by 2015. Prior to the intervention, confirmed rabies cases in dogs were between 19 and 50 per year (2008-2011). The primary outcome of the project was a reduction in rabies cases in both dogs and humans to 0 in 2014 and 2015, which has subsequently been maintained. Animal bite consultations increased significantly during the project. Economic data for the dog vaccination and PEP components of the project were collated for two sites: Laoag City (an urban setting) and Dingras Municipality (a rural setting) between 2012 and 2014. The average programmatic cost of vaccinating each dog was $4.54 in Laoag City and $8.65 in Dingras, and costs fell as the project reached more dogs. The average costs of providing PEP were $69.72 per patient and $49.02 per patient for the two sites, respectively, again falling as the project reached more people. External donor contributions contributed less than 20% of dog vaccination costs and less than 1% of PEP costs. The project demonstrated that rabies elimination can be achieved in a short period of time, with concerted effort across multiple sectors. A lack of clear dog population estimates hampered interpretation of some aspects of the programme. From 2016, the provincial government has assumed complete responsibility for the programme and must now continue the vaccination and surveillance efforts. Although safeguards are in place

    Results from a recent glacio-meteorological experiment on the Juncal Norte glacier, in central Chile, are presented. Melt water is a crucial resource in the Central Andes, as it provides drinking water, water for agriculture and for industrial uses. There is also increasing competition for water use and allocation, as water demands from mining and industry are rising. Assessing water availability in this region and its relation with climatic variations is therefore crucial. The Dry Central Andes are characterised by a climatic setting different from that of the Alps and the subtropical Andes of Bolivia and Peru. Summers are very dry and stable, with precipitation close to zero and low relative humidity. Solar radiation is very intense, and plays a key role in the energy balance of snow covers and glaciers. The main aim of this study is to investigate the glacier-climate interaction in this area, with particular attention devoted to advanced modelling techniques for the spatial redistribution of meteorological variables, in order to gain an accurate picture of the ablation processes typical of these latitudes. During the ablation season 2005/2006, an extensive field campaign was conducted on the Juncal Norte glacier, aimed at monitoring the melt and runoff generation processes on this remote glacier in the dry Andes. Melt rates, runoff at the snout, meteorological variables over and near the glacier, GPS data and glacier topography were recorded over the entire ablation season. Using this extensive and accurate data set, the spatial and temporal variability of the meteorological variables that drive the melt process on the glacier is investigated, together with the process of runoff generation. An energy balance model is used to simulate melt across the glacier, and special attention is devoted to the modelling of the solar radiation energy flux. The components of the energy balance are compared with those of Alpine basins. The validity of parameterisations of the

    This study analyzes the practices and organization of Family Health Program, in the municipality of Juazeiro do Norte according to the discussion of elements that feature the primary attention, as proposed by Starfield. The theoretical context chosen understands the primary attention as a level of attention organized by the features: First contact, longitude, integrality, coordination. This is a qualitative research, using focus group techniques, semi-structured interview and non-participant observation in eight family health units in the municipality. There are difficulties in accessing the primary care in the units, caused by structural barriers imposed to the organization of attention, represented by an excess of clients for each team and reduced availability of medical professional. Considering that there are a compulsory enrollment of the population to the Family Health Care program health units, this level of attention in the city presents itself as a traditional doctor-hegemonic model of healing practices associated with the prioritization of vertical programs of the Ministry of Health.

  19. Study of NO2 photolysis rate coefficients for the Paso Del Norte region

    Wangchuk, Pema

    The photolysis of NO2 is one of the most influential chemical processes in the formation of photochemical air pollution. In this study, we compared simulated and measured nitrogen dioxide photolysis rate coefficients (JNO2) for the Paso Del Norte (PdN) region. The Tropospheric Ultraviolet-Visible (TUV) radiation transfer model was used to calculate J(NO2) values. The measurements of hemi-spherically integrated, spectrally resolved solar photon flux between the wavelengths 400 and 700 nm were used to obtain the photolysis rate coefficients for NO2. Results are presented for a selected episode on July, 2015. The work investigated the use of measured actinic flux to improve the NO2 photolysis rate coefficients used by air quality models in order to predict more accurately nitrogen dioxide concentrations for the PdN Region. Complimentary to this work, simulated irradiances at visible wavelengths for the PdN region were inter-compared with Multi-filter Rotating ShadowBand radiometer irradiances data. TUV program was successfully enhanced to tailor it for the PdN region which results in an improved methodology in optimizing the photolysis rate coefficients to increase the accuracy of air quality and forecasting capability.

    In this research work we are focusing on understanding the relationship between photolysis rates and the photochemical ozone changes observed in the Paso del Norte region. The city of El Paso, Texas together with Ciudad Juarez, Mexico, forms the largest contiguous bi-national metropolitan area. This region suffers year-round ozone pollution events, and a better understanding is needed to mitigate them. Previous studies have found that ambient ozone concentrations tend to be higher on weekends rather than on weekdays, this phenomenon being referred to, as the ``weekend effect.'' If the ozone standard is exceeded more frequently on weekends, then this phenomenon must be considered in the design of ozone control strategies. In this work we investigate some of the most representative weekend ozone episodes at El Paso, TX, during the years 2009, 2010 and 2011 using the ozone photolysis rates. In this research the TUV radiative-transfer model is used to calculate the local photolysis rates and a UV MFRSR instrument is used to obtain experimental parameters. Seasonal variations and the weekday-weekend effect is studied. The results of this research will help to understand the underlying behavior of the photolysis rate constants when different atmospheric conditions are present.

    The Norte Chico region on the coast of Peru north of Lima consists of four adjacent river valleys--Huaura, Supe, Pativilca and Fortaleza--in which archaeologists have been aware of a number of apparently early sites for more than 40 years (refs 1- 3). To clarify the early chronology in this region, we undertook fieldwork in 2002 and 2003 to determine the dates of occupation of sites in the Fortaleza and Pativilca valleys. Here we present 95 new radiocarbon dates from a sample of 13 of more than 20 large, early sites. These sites share certain basic characteristics, including large-scale monumental architecture, extensive residential architecture and a lack of ceramics. The 95 new dates confirm the emergence and development of a major cultural complex in this region during the Late Archaic period between 3000 and 1800 calibrated calendar years bc. The results help to redefine a broader understanding of the respective roles of agricultural and fishing economies in the beginnings of civilization in South America.

    The volcanic fields of San Borja and Jaraguay, Baja California Norte; include monogenetic, composite and ignimbrite volcanism, distributed between 30° and 28° north latitude, product of the stages of tecto-magmatic activity of the last 23 Ma. This study reports the results of 230 cores from 27 sites, mainly in lava flows of magnesium andesite composition and all with radiometric ages known. The results of rock magnetic experiments as susceptibility vs. temperature, hysteresis and demagnetization processes, suggest the presence of only one mineralogical phase (reversibility) present with slight changes, PSD magnetic domain type and just one component of magnetization (univectorial diagram). This makes paleointensity experiments have a high probability of success, which we will present at the meeting. The temporal distribution of sites sampled was divided into two main periods: 2.6 - 6.3 Ma (19 sites) and 8.12 - 14.64 Ma (8 sites), which will be used for the analysis of paleosecular variation of the geomagnetic field.

    In this work we show preliminary results of the application of the methodology proposed by Corripio (2004) for albedo estimation of a glacial surface using oblique photography. This analysis was performed for the Glaciar Norte of Citlaltepetl volcano (Mexico), using images obtained with a modified digital camera for capturing the portion of the near infrared spectrum starting at 950 nm and a digital elevation model with a grid of 2 m. The main goal was to obtain a picture of the spatial distribution of albedo on the glacier, in order to find out if there was any morphological evidence of the influence of the glacier energy balance. Some of the obtained results show a certain spatial distribution with comparatively higher albedo values at the lower parts of the glacier as compared with higher parts. The higher values may correspond to different metamorphism of snow/ice at different heights due to the effects of lower slope. Corripio, J. G. (2004).

    Surface ozone pollution has been a persistent environmental problem in the US and Europe as well as the developing countries. A key prerequisite to find effective alternatives to meeting an ozone air quality standard is to understand the importance of local anthropogenic emissions, the significance of biogenic emissions, and the contribution of long-range transport. In this study, an air quality modeling system that includes chemistry and transport, CMAQ, an emission processing model, SMOKE, and a mesoscale numerical meteorological model, WRF, has been applied to investigate an ozone event occurring during the period of the 1996 Paso del Norte Ozone Campaign. The results show that the modeling system exhibits the capability to simulate this high ozone occurrence by providing a comparable temporal variation of surface ozone concentration at one station and to capture the spatial evolution of the event. Several sensitivity tests were also conducted to identify the contributions to high surface ozone concentration from eight VOC subspecies, biogenic VOCs, anthropogenic VOCs and long-range transportation of ozone and its precursors. It is found that the reductions of ETH, ISOP, PAR, OLE and FORM help to mitigate the surface ozone concentration, and like anthropogenic VOCs, biogenic VOC plays a nonnegligible role in ozone formation. But for this case, long-range transport of ozone and its precursors appears to produce an insignificant contribution.

    Meteorological simulations centered around the border cities of El Paso and Ciudad Juárez have been performed during an ozone episode that occurred on August 13, 1996 during the 1996 Paso del Norte Ozone Study field campaign. Simulations were performed using the HOTMAC boundary-layer meteorological model using a 1, 2, 4 and 8-km horizontal grid size nested mesh system. Investigation of the vertical structure and evolution of the atmospheric boundary layer for the August 12-14 time period is emphasized in this paper due to its suspected importance in precipitating the ozone episode [Sci Total Environ (2001)]. This period was characterized by a slowly-evolving high pressure system over the region, a persistent upper-level jet at 2500-3500 m above ground level (agl), deep daytime mixed layer heights of 3500 m depth and unusually deep nighttime stable layers extending up to 2500 m above the ground. The fact that the boundary-layer growth stalled on the morning of August 13 relative to that on August 12 has been suggested as a possible reason for the ozone episode on the 13th. In addition, relatively weak surface-level winds were measured on August 13. Using both model results and experimental data we hypothesize explanations for the slower mixed-layer growth on the morning of the 13th and the stronger surface-level winds found on the 12th and 14th.

    Meteorological simulations centered around the border cities of El Paso and Ciudad Juarez have been performed during an ozone episode that occurred on Aug. 13,1996 during the 1996 Paso del Norte Ozone Study field campaign. Simulations were petiormed using the HOTMAC mesoscale meteorological model using a 1,2,4, and 8 km horizontal grid size nested mesh system. Investigation of the vertical structure and evolution of the atmospheric boundary layer for the Aug. 11-13 time period is emphasized in this paper. Comparison of model-produced wind speed profiles to rawirisonde and radar profiler measurements shows reasonable agreement. A persistent upper-level jet was captured in the model simulations through data assimilation. In the evening hours, the model was not able to produce the strong wind direction shear seen in the radar wind profiles. Based on virtual potential temperature profile comparisons, the model appears to correctly simulate the daytime growth of the convective mixed layer. However, the model underestimates the cooling of the surface layer at night. We found that the upper-level jet significantly impacted the turbulence structure of the boundary layer, leading to relatively high turbulent kinetic energy (tke) values aloft at night. The model indicates that these high tke values aloft enhance the mid-morning growth of the boundary layer. No upper-level turbulence measurements were available to verify this finding, however. Radar profiler-derived mixing heights do indicate relatively rapid morning growth of the mixed layer.

    Baja California is a peninsula in western Mexico that was formed through a dynamic tectonic history of convergence, rifting and strike slip motion. At approximately 13 Ma, subduction along the northwestern coast of Mexico stopped, subsequently the Gulf of California opened and strike slip faults formed parallel to the ancient trench. After subduction ended, arc-related magmatism continued as the Baja peninsula was forming until about 2 Ma. The lavas erupting in the peninsula have variable compositions including calc-alkalic and tholeiitic arc basalts and bajaites. The term bajaite is a collective term for the high magnesian andesites and basaltic andesites in Baja California that have adakitic characteristics. Adakites, on the other hand, are arc lavas characterized by high silica content and Sr/Y and La/Yb ratios; these are generally believed to have formed through melting of subducted basaltic crust. The origin of bajaite is controversial. It has been proposed as product of melting of either subducted basaltic crust primarily because of its adakitic characteristics (Saunders et al, 1987) or metasomatized mantle wedge because of its arc lava-like geochemical features (Castillo, 2008); it has also been proposed as a mixture of differentiated and mafic arc lavas (Streck et al, 2007). The composition of bajaite is similar to that of the bulk continental crust and, thus, its true origin can shed light on the mechanism for continental growth. In this study, we use geochemical techniques to resolve some of the controversies surrounding the origin of bajaite. We analyze the petrographic, major element, trace element, and Sr-Nd-Pb isotopic compositions of bajaites from the San Borja Volcanic Field in Baja California Norte, Mexico to better constrain their petrogenetic history and origin.

    The San Diego Norte Pilot Project consists of twelve inclined wells (7 producing wells 300 m (984 ft) apart, plus 5 observation wells) drilled from a cluster, to study the production and compaction behavior under steam soak (huff and puff) of the Tertiary heavy crude oil reservoirs of the Zuata area. This area is located within the Orinoco Heavy Oil belt of Venezuela. A geological model was needed as a base for the reservoir studies and to understand the geological setting. This model was constructed from extensive log information, seismic lines, well samples, and cores. The reservoir sands are friable with an average porosity of 34% and permeabilities ranging from 1 to 7 ..mu..m/sup 2/ (1 to 7 darcys). The sands were deposited in meander belts that stacked up forming multistory bodies. Point bars and channel fills account for 80-90% of the total sand. These sands are internally heterogeneous, sinuous and elongated, and larger than the 1 km/sup 2/ area covered by the project. The topmost two productive sands, which together average 22 m (72 ft), show the best porosities and permeabilities and are isolated by thick clays that make them suitable for selective steam injection. In the project, the oil has a density of about 1.0 g/cm/sup 3/ (10/sup 0/ API) and fills all the sands down to the oil-water contact. The depth of this contact is controlled by regional faults. Based on core compressibility tests, compaction is expected to be the principal production mechanism that could increase the expected primary recovery of 4 to 12% by huff and puff steam injection, leading to a possible recovery of 0.64 x 10/sup 6/ m/sup 3/ (4 million bbl) in six years with four cycles of steam injection. 16 figures, 2 tables.

    The complex tectonic region of NE Caribbean, where Hispaniola and Puerto Rico are located, is bordered by subduction zone with oblique convergence in the north and by incipient subduction zone associated to Muertos Trough in the south. Central Caribbean basin is characterized by the presence of a prominent topographic structure known as Beata Ridge, whose oceanic crustal thickness is unusual. The northern part of Beata Ridge is colliding with the central part of Hispaniola along a transverse NE alignment, which constitutes a morphostructural limit, thus producing the interruption of the Cibao Valley and the divergence of the rivers and basins in opposite directions. The direction of this alignment coincides with the discontinuity that could explain the extreme difference between west and east seismicity of the island. Different studies have provided information about Beata Ridge, mainly about the shallow structure from MCS data. In this work, CARIBE NORTE (2009) wide-angle seismic data are analyzed along a WNW-ESE trending line in the northern flank of Beata Ridge, providing a complete tectonic view about shallow, middle and deep structures. The results show clear tectonic differences between west and east separated by Beata Island. In the Haiti Basin area, sedimentary cover is strongly influenced by the bathymetry and its thickness decreases toward to the island. In this area, the Upper Mantle reaches 20 km deep increasing up to 24 km below the island where the sedimentary cover disappears. To the east, the three seamounts of Beata Ridge provoke the appearance of a structure completely different where sedimentary cover reaches thicknesses of 4 km between seamounts and Moho rises up to 13 km deep. This study has allowed to determine the Moho topography and to characterize seismically the first upper mantle layers along the northern Beata Ridge, which had not been possible with previous MCS data.

    The 1996 Paso del Norte (PdN) ozone study was conducted to improve current understanding of the significant meteorological and air quality processes that lead to high concentrations of ozone in El Paso, Texas (USA) and Ciudad Juárez, Chihuahua (Mexico). Two-hour canister samples were collected five times daily at 05.00-07.00 h, 07.00-09.00 h, 09.00-11.00 h, 11.00-13.00 h, and 15.00-17.00 h MST during intensive study periods at one urban and one rural site on each side of the border. An automated gas chromatograph was operated at one site in central El Paso. Source profiles (the fractional chemical composition of emissions) from motor vehicles, gasoline, liquefied petroleum gas, and commercial natural gas were combined with source profiles from other studies for input to the Chemical Mass Balance (CMB) receptor model to apportion the measured non-methane hydrocarbons (NMHC) to sources. On-road vehicle emissions accounted for one-half to two-thirds of the NMHC in Ciudad Juárez and El Paso with the highest contributions occurring during the morning and afternoon commute periods. Emissions from diesel exhaust contributed approximately 2-3% of NMHC in Ciudad Juárez and less than 2% in El Paso. The average sum of liquid gasoline and gasoline vapor increased during the day in Ciudad Juárez from 2% at 06.00 h to approximately 12% at 16.00 h. Diurnal and day-of-the-week patterns in the liquid gasoline contributions are essentially identical to the corresponding patterns for motor vehicle exhaust, which suggest that a large fraction of the liquid gasoline contribution may be associated with tailpipe emissions rather than evaporative emissions from motor vehicles or industrial sources. Including the sum of the two sources put the upper limit for tailpipe contributions at 60-70% of NMHC.

    The recognition of communities of arthropods with medical importance in natural systems constitutes an important step in the prediction of possible epidemic events and/or emergence of infectious diseases in the human population. This is due to anthropogenic impact in natural areas and landscape modification, which changes the dynamics of pathogenic agents, reservoirs, and vector insects. In this study, an inventory was compiled of species of the genus Lutzomyia present in sub-Andean forest from the confluence of the Pamplonita River basin. CDC-light and Shannon traps were used for collecting adult phlebotomine sandflies during the month of October 2013 in a sub-Andean forest from river basin Pamplonita. All specimens were identified using morphological keys. The epidemiological relevance of each species was reported using a literature review about natural infection or vector incrimination with Leishmania species or other pathogens microorganism. A total of 2755 specimens belonging to eight species of the genus Lutzomyia were collected. Out of the eight species, seven belonged to the group verrucarum (Lutzomyia sp--townsendi series, L. ovallesi, L. spinicrassa, L. serrana, L. townsendi, L. nuneztovari and L. pia), while one belonged to the subgenus Helcocyrtomyia (L. hartmanni). A new registry of L. townsendi was observed for the Norte de Santander department. The appreciable diversity of the verrucarum group observed in this area suggest further investigation on the biogeography and evolution of this group, and epidemiological risk for human populations around this area, as there are reports of Leishmania natural infection and favourable conditions for domestication of phlebotomines in rural towns.

    Ambient air VOC samples were collected at surface air quality monitoring sites, near sources of interest, and aloft on the US (El Paso) and Mexican (Ciudad Juárez) side of the border during a six-week period of the 1996 Paso del Norte Ozone Study. Samples were collected at five sites, three on the US side and two on the Mexican side, during nine intensive operation days when high ozone levels were forecast for the area. Six other sites were sampled to characterize up-wind, down-wind and other emission sources. Samples for determining source profiles were collected for rush hour traffic, propane-powered bus exhaust, automobile paint shop emissions, propane fuels, and industrial manufacturing in Cd. Juárez and a refinery in El Paso. Most samples were collected in electro-polished stainless steel canisters for determination of C2 to C(10+) hydrocarbons by GC-FID. Carbonyl samples were collected on DNPH impregnated cartridges at three surface sites during aircraft flights and analyzed by HPLC. This paper presents the spatial and temporal characteristics of VOC species concentrations and compositions to examine the differences and similarities of the various locations and time periods. Overall surface, total non-methane hydrocarbon values ranged from 0.1 to 3.4 ppmC with the highest concentrations being recorded in the morning and evening at five vehicle-dominated sites, three in Cd. Juárez and two in El Paso. Toluene in El Paso samples and propane, which is used as a cooking and transportation fuel in Cd. Juárez, were the most abundant hydrocarbons. The most abundant carbonyls were acetaldehyde, acetone and formaldehyde.

    Air pollution in the Paso del Norte region, where West Texas abuts the southern boundary of New Mexico and the northern boundary of Chihuahua, Mexico is a common concern to the residents on both sides of the border. Parts of the region fail to meet the US and Mexican Ambient Air Quality Standards for particulate matter, ozone, and carbon monoxide. The regional air pollution problem is complicated due to arid climate, complex terrain topography, frequently occurring temperature inversions, extensive unpaved urban areas, an aging and poorly maintained vehicle fleet, and a number of other uncontrolled anthropogenic emission sources. The issue is further complicated by concerns arising from recent scientific evidence of the health effects associated with exposures to fine particulate matter. A study designed to address particulate matter (PM) air pollution problems in the region is currently undertaken by researchers from member universities of the Southwest Center for Environmental Research and Policy and several governmental agencies. The study attempts to (1) characterize the fine fraction of PM; (2) identify and characterize the major regional emission sources; (3) apportion the fine fraction of PM to the source emissions; and (4) establish a regional technological information clearinghouse. The short-term goal of this research is to initiate a research program to characterize, identify, and quantify the sources and nature of the PM in the region. The long-term goal of this study is to establish regional research capabilities to continue air quality monitoring, evaluation, modeling, and control after the implementation of the study. A scoping study to collect regional PM was conducted in December 1998.

    In the Aconcagua River Basin, in the dry Andes of central Chile, water resources in summer originate mostly from snow and ice glacier melt. Summer seasons are dry and stable, with precipitation close to zero, low relative humidity and very intense solar radiation. The region's economic activities are dependent on these water resources, but their assessment is still incomplete and an effort is needed to evaluate present and future changes in water from glacier and seasonal snow covers in this area. The main aim of this paper is to simulate glacier melt and runoff from Juncal Norte Glacier, in the upper Aconcagua Basin, using models of various complexity and data requirement. We simulate distributed glacier ablation for two seasons using an energy-balance model (EB) and an enhanced temperature-index model (ETI). Meteorological variables measured at Automatic Weather Stations (AWSs) located on and off-glacier are extrapolated from point observations to the glacier-wide scale. Shortwave radiation is modelled with a parametric model taking into account shading, reflection from slopes and atmospheric transmittance. In the energy-balance model, the longwave radiation flux is computed from Stefan-Boltzmann relationships and turbulent fluxes are calculated using the bulk aerodynamic method. The EB model includes subsurface heat conduction and gravitational redistribution of snow. Glacier runoff is modelled using a linear reservoir approach accounting for the temporal evolution of the system. Hourly simulations of glacier melt are validated against ablation observations (ultrasonic depth gauge and ablation stakes) and runoff measured at the glacier snout is compared to a runoff record obtained from a combination of radar water level measurements and tracer experiments. Results show that extrapolation of meteorological input data, and of temperature in particular, is the largest source of model uncertainty, together with snow water equivalent initial conditions. We explore

    The primary purpose of this study was to determine if methicillin-resistant Staphylococcus aureus (MRSA) strains could be identified in the milk of dairy cattle in a Paso del Norte region dairy of the United States. Using physiological and PCR-based identification schemes, a total of 40 Staph. aureus strains were isolated from 29 raw milk samples of 133 total samples analyzed. Pulsed-field gel electrophoresis after digestion with the SmaI enzyme revealed that the 40 confirmed strains were represented by 5 pulsed-field types, which each contained 3 or more strains. Of 7 hospital strains isolated from cows undergoing antibiotic therapy, 3 demonstrated resistance to 3 or more antimicrobial classes and displayed similar pulsed-field gel electrophoresis patterns. A secondary purpose of this study was to elucidate the evolutionary relationships of strains isolated in this study to genomically characterized Staph. aureus strains. Therefore, Roche 454 GS (Roche Diagnostics Corp., Dallas, TX) pyrosequencing was used to produce draft genome sequences of an MRSA raw milk isolate (H29) and a methicillin-susceptible Staph. aureus (PB32). Analysis using the BLASTn database (http://blast.ncbi.nlm.nih.gov/) demonstrated that the H29 draft genome was highly homologous to the human MRSA strain JH1, yet the β-lactamase plasmid carried by H29 was different from that carried by JH1. Genomic analysis of H29 also clearly explained the multidrug resistance phenotype of this raw milk isolate. Analysis of the PB32 draft genome (using BLASTn) demonstrated that this raw milk isolate was most related to human MRSA strain 04-02981. Although PB32 is not a MRSA, the PB32 draft genome did reveal the presence of a unique staphylococcal cassette mec (SCCmec) remnant. In addition, the PB32 draft genome revealed the presence of a novel bovine staphylococcal pathogenicity island, SaPIbovPB32. This study demonstrates the presence of clones closely related to human and (or) bovine Staph. aureus strains

    This paper summarizes the measurement campaigns of the 1996 and 1997 Paso del Norte Ozone Studies, the resultant data sets, and the findings and conclusions that arose from subsequent data analyses. The purpose of these data analyses was to develop an understanding of the significant chemical and physical processes that lead to high concentrations of ozone in the Paso del Norte study region which includes El Paso, TX; Sunland Park, NM; and Juarez, Mexico. High ozone concentrations resulted from a combination of conditions, including slow convective boundary layer (CBL) growth, reduced CBL depth, light surface winds, and high concentrations of ozone precursor at ground level in the morning. Synoptic-scale meteorological conditions observed during high ozone episodes included an upstream aloft high-pressure system, and aloft warming. Aloft carryover of ozone and ozone precursors did not significantly contribute to the surface ozone concentration. Furthermore, hydrocarbon and NO{sub x} data, although spatially limited, showed that the system is more often NO{sub x}-limited rather than VOC-limited.

    α-Thalassemia, arising from a defect in α-globin chain synthesis, is often caused by deletions involving one or both of the α-genes on the same allele. With the aim of investigating the prevalence of α-thalassemia 3.7 kb deletion in the adult population of Rio Grande do Norte, 713 unrelated individuals, between 18 and 59 years-of-age, were analyzed. Red blood cell indices were electronically determined, and A2 and F hemoglobins evaluated by HPLC. PCR was applied to the molecular investigation of α-thalassemia 3.7 kb deletion. Eighty (11.2%) of the 713 individuals investigated presented α-thalassemia, of which 79 (11.1%) were heterozygous (-α3.7/αα) deletions and 1 (0.1%) homozygous (-α3.7/-α3.7). Ethnically, heterozygous deletions were higher (24.8%) in Afro-Brazilians. Comparison of hematological parameters between individuals with normal genotype and those with heterozygous α+-thalassemia showed a statistically significant difference in the number of erythrocytes (p < 0.001), MCV (p < 0.001), MCH (p < 0.001) and Hb A2 (p = 0.007). This study is one of the first dedicated to investigating α-thalassemia 3.7 kb deletion in the population of the State Rio Grande do Norte state. Results obtained demonstrate the importance of investigating this condition in order to elucidate the causes of microcytosis and hypochromia. PMID:23055797

  19. COMO - A Program For Optical Design

    Vollrath, Wolfgang

    1986-10-01

    COMO is an optical design program of a special orthogonalization type, developed by Prof. H.Marx at Ernst Leitz Wetzlar Company. Not using a merit function, COMO corrects aberrations under equality and inequality constraints not simultaneously but sequentially, the order is chosen by the optical designer. The optimization procedure shows distinctive features compared to other programs. COMO is in use at Leitz since the early 1970's and is now running on HP-1000F and HP-A900 computer systems. In 1974, when it was implemented on a HP-2100, it was probably one of the very first "mainfrawe" optical design programs running on a minicomputer. H.Marx named this program COMO.

    1996-01-01

    The first topographic and ice-motion maps of the northwestern flank of Hielo Patagonico Norte (HPN, northern Patagonia Icefield), in Chile, were produced using satellite synthetic-aperture interferometric radar data acquired by NASA's Spaceborne Imaging Radar C instrument in October 1994. The topographic map has a IO m vertical precision with a 30 m horizontal spacing, which should be sufficient to serve as a reference for monitoring future mass changes of the icefield. The ice-motion map is accurate to within 4 mm/ d (or 1/ ma). The radar-derived surface topography and ice velocity are used to estimate the ice discharge from the accumulation area of four outlet glaciers, and the calving flux and mass balance of Glaciar San Rafael. The results demonstrate the use of SAR interferometry for monitoring glaciological parameters on a spatial and temporal scale unattainable by any other means.

    Since dogs presenting several vector borne diseases can show none or nonspecific clinical signs depending on the phase of infection, the assessment of the particular agents involved is mandatory. The present study aimed to investigate the presence of Babesia spp., Ehrlichia spp., Anaplasma spp., Hepatozoon spp. and Leishmania spp. in blood samples and ticks, collected from two dogs from Rio Grande do Norte showing suggestive tick-borne disease by using molecular techniques. DNA of E. canis, H. canis and L. infantum were detected in blood samples and R. sanguineus ticks collected from dogs. Among all samples analyzed, two showed the presence of multiple infections with E. canis, H. canis and L. infantum chagasi. Here we highlighted the need for molecular differential diagnosis in dogs showing nonspecific clinical signs.

  5. Analysis of policy options for meeting the demand for wood fuels in the province of Ilocos Norte, the Philippines

    Ilocos Norte is the second most deforested province in the Philippines. It has a high demand for wood fuels for household cooking and tobacco curing. The government has constructed a 3-MW wood-fired electric power plant and is planning two pig iron furnaces that will require large amounts of wood charcoal. Key options for producing or saving large quantities of wood fuels are tree farming, improved woodstoves, bamboo substitution, and kerosene substitution. At realistic rather than ideal implementation effectiveness, the present value of net economic benefits (PVNB) is highest for woodstoves. Tree farming has the second highest PVNB when fuelwood is valued at the market price, but bamboo substitution does when fuelwood is shadow priced at the value of collection time. Kerosene substitution has a negative PVNB, and LPG or electricity are even more expensive fuels.

    The scope of this study was to identify socioeconomic contextual and health care factors in primary care associated with maternal near misses and their marker conditions. This is an ecological study that used aggregated data of 63 clusters formed by the municipalities of State of Rio Grande do Norte, Brazil, using the Skater method of area regionalization, as the unit of analysis. The ratio of maternal near misses and their marker conditions were obtained from the Hospital Information System of the Brazilian Unified Health System. In multiple linear regression analysis, there was a significant association between maternal near misses and variables of poverty and poor primary health care. Hypertensive disorders were also associated with poverty and poor primary care and the occurrence of hemorrhaging was associated with infant mortality. It was observed that the occurrence of maternal near misses is linked to unfavorable socioeconomic conditions and poor quality health care that are a reflection of public policies that accentuate health inequalities.

    COMO is a program of an orthogonalization type that was developed in order to achieve that each elementary correction step makes immediate use of the shortest possible step in the system data space even if many rigid boundary conditions are to be taken into account (optimization under constraints). COMO usually does not correct aberrations simultaneously (by minimization), but one after the other. The order is given by the optical designer. For each aberration (paraxial data included) one can either specify a target value or a bandwidth between a lower and an upper limit.

    Background Human communities consistently develop a detailed knowledge of the therapeutical and medicinal properties of the local flora and fauna, and these folk remedies often substitute medicines produced by the pharmaceutical industry. Animals (and their derived products) are essential ingredients in the preparation of many traditional remedies. The present work prepared an inventory of the animals sold in public markets in the cities of Crato and Juazeiro do Norte, Ceará State, Brazil. Methods Information was obtained through the use of semi-structured questionnaires in interviews held with 27 merchants of medicinal animals (18 in the municipality of Juazeiro do Norte [11 men and 7 women] and 9 people in the municipality of Crato [6 men and 3 women]). We calculated the Informant Consensus Factor (ICF) to determine the consensus over which species are effective for particular ailments, as well as the species Use Value (UV) to determine the extent of utilization of each species. Results A total of 31 animal species, distributed among 21 families were identified as being used medicinally. The taxa most represented were: insects (8 species), mammals (7), fish (5), reptiles (5) and birds (4). The animals sold in these markets are used to treat a total of 24 ailments, with rheumatism, asthma, and inflammations having the largest numbers of citations. Three species not previously reported as having medicinal use were encountered: Leporinus steindachneri (utilized for treating cholesterol problems), Gryllus assimilis (utilized in treating urinary infections), and Phrynops tuberosus (used to treat asthma, rheumatism and bruises). Conclusion The composition of the local fauna, the popular culture, and commercial considerations are factors that maintain and drive the market for therapeutic animal products – and the lack of monitoring and regulation of this commerce is worrisome from a conservationist perspective.

    The Acu Valley is the lower part of the Rio Piranhas valley in the northwestern part of the State of Rio Grande do Norte, Brazil. It begins where the Rio Piranhas leaves the crystalline Precambrian rocks to flow across the outcrop of sedimentary rocks. The area considered in this report extends northward for about 45 kilometers; it is terminated arbitrarily where encroachment by sea water has contaminated the aquifer and imparted a disagreeable saline taste to the water in it. The boundary was not determined in the field, however, for lack of special equipment. Part of the extensive uplands on either side of the valley are included. This makes the total area approximately 2,500 square kilometers. The largest town, Acu, had a population of about 8,000 in 1960. The area is considered to be part of the Drought Polygon of northeast Brazil because the precipitation, although averaging 448 millimeters annually at Acu, varies widely from year to year and often is deficient for many months. The precipitation has been supplemented by use of irrigation wells, but irrigated agriculture is not yet far advanced, and the quantities of water used in irrigation are small. Geologically, the area consists of basement crystalline rocks (Precambrian), a wedge of sedimentary rocks thickening northward (Cretaceous), and alluvial sediments constituting a narrow band in the bottom of the valley (Alluvium and terrace deposits). The crystalline rocks contain water mainly in fractures and, in general, are impermeable. The sedimentary rocks of Cretaceous age comprise two units: a thick but fine-grained sandstone grading upward into siltstone and shale (Acu Sandstone), and limestone and dolomite with an included shale zone (Jandaira Limestone). The sandstone especially and the limestone to a lesser degree are ground-water reservoirs of large capacity. The limestone has been tapped at several places, but the sandstone and its contained water are practically untested and, hence, imperfectly

    βS haplotypes were studied in 47 non-related patients with sickle-cell anemia from the state of Rio Grande do Norte, Brazil. Molecular analysis was conducted by PCR/RFLP using restriction endonucleases XmnI, HindIII, HincII and HinfI to analyze six polymorphic sites from the beta cluster. Twenty-seven patients (57.5%) were identified with genotype CAR/CAR, 9 (19.1%) CAR/BEN, 6 (12.8%) CAR/CAM, 1 (2.1%) BEN/BEN, 2 (4.3%) CAR/Atp, 1 (2.1%) BEN/Atp and 1 (2.1%) with genotype Atp/Atp. The greater frequency of Cameroon haplotypes compared to other Brazilian states suggests the existence of a peculiarity of African origin in the state of Rio Grande do Norte. PMID:21931513

    1989-10-01

    New geological studies of the Camarines Norte-Calaguas Islands (CNCI) basement complex have resulted in the identification of a pre-Late Cretaceous ophiolite assemblage underlying much of the eastern part of the complex. Dominant ophiolite lithologies include: harzburgites, gabbros, diabasic and basaltic dikes, and pillow lavas. A stratigraphically complete igneous section is lacking due to extensive structural disruption of the ophiolite by westward directed thrusting and displacement along high angle faults. Despite this disruption, geochemical ([ La/ Yb] n ⩽ 1, La/ Ta ≈ 15) and mineralogical data, as well as field relationships, support a cogenetic (N-MORB) origin for the basalt and gabbro units. A minimum crustal age of 100 Ma is inferred from recent {40Ar }/{39Ar } analyses of amphibolites associated with the gabbros. Other lithologies occurring within the basement complex include: medium to high-grade garnet-hornblende-mica schists, low-grade metaigneous rocks, and dioritic and granodioritic intrusives. Geological and geochemical data on these units indicate that they are not genetically related to the ophiolite but have been in close spatial proximity since the Middle Miocene. Together these studies raise new questions concerning the nature of Philippine basement complexes and extent of fundamental, pre-Tertiary basement in the eastern Philippines.

    The dengue viral infection is one of the most relevant vector-borne diseases in the world. The disease can manifest in a variety of forms, from asymptomatic to a condition of dengue hemorrhagic fever (DHF). The last reported cases in Brazil correspond to 80% of the cases reported in the Americas, which emphasizes the magnitude of the problem. This study was conducted using Geographic Information System (GIS) techniques, in order to evaluate the spatial distribution of the disease in the urban area of Mossoró, Rio Grande do Norte. In the period between 2001 and 2007, 867 new cases were listed. About 85.7% of the addresses were georeferenced, with a larger number of cases, 14.8%, in the neighborhoods of Santo Antônio and Santa Delmira (north region), and 11.7% in the neighborhoods of Conjunto Vingt-Rosado and Alto de São Manoel (east region). There were 18 confirmed cases of dengue hemorrhagic fever associated with regions with the highest incidence of classic cases of the disease. The use of Geographic Information System (GIS) proved a great benefit for better visualization of the endemic, especially in elucidating the actual distribution of dengue cases in the county and providing an effective tool for planning the monitoring of the disease at a local level.

    Gaucher's disease (GD) is caused by a β-glucocerebrosidase deficiency, leading to the accumulation of glucocerebroside in the reticuloendothelial system. The prevalence of GD in Tabuleiro do Norte (TN) (1:4000) is the highest in Brazil. The purpose of this study was to present evidence of consanguinity and founder effect for the G377S mutation (c.1246G>A) among GD patients in TN based on enzyme, molecular and genealogical studies. Between March 2009 and December 2010, 131 subjects at risk for GD (GC in dried blood ≤2.19 nmol/h/ml) and 5 confirmed GD patients from the same community were submitted for molecular analysis to characterize the genetic profile of the population. Based on the enzymatic and molecular analysis, the subjects were classified into three categories: affected (n = 5), carrier (n = 20) and non-carrier (n = 111). All carriers were (G377S/wt). Affected subjects were homozygous (G377S/G377S). The identification of a single mutation in carriers and homozygotes from different generations, the history of the community and the genealogy study suggest that the high prevalence of GD in this population may be due to a combination of consanguinity and founder effect for the G377S mutation. © 2014 John Wiley & Sons A/S.

    1990-10-01

    The volcanogenic massive sulfide deposit of Filon Norte at Tharsis is hosted by carbonaceous black slate and connected only partly with stockwork veins. The massive ores are usually composed of fine-grained pyrite with subordinate amounts of sphalerite, chalcopyrite, galena and arsenopyrite. Monoclinic pyrrhotite sometimes occurs in massive pyritic ores in the apparently middle and upper horizons of the orebody, and siderite-rich ores are interstratified with compact pyritic ores in the apparently lower horizons. From the occurrence of monoclinic pyrrhotite, together with the FeS contents of sphalerite mostly ranging from 11 to 16 mol %, it is inferred that the sulfide minerals of the massive orebody were precipitated in euxinic muds on the sea-floor at temperatures below 250°C. The negatively shifted, highly variable δ 34S values of the massive ores and their close similarity to those of the underlying black slates strongly suggest that the sulfide sulfur of the massive orebody and the slates is cognate and biogenic.

    The ability of some plants to take up metal contaminants in the soil has been of increasing interest as an environmental approach to pollution clean-up. This study aimed to assess the ability of Pteris melanocaulon for copper(Cu) uptake by determining the Cu levels in the fern vis-à-vis surrounding soil and the location of Cu accumulation within its biomass. It also aimed to add information to existing literature as P. melanocaulon are found to be less documented compared to other fern metal accumulators, such as P. vittata. The P. melanocaulon found in the Suyoc Pit of a Copper-Gold mine in Placer, Surigao del Norte, Philippines exhibited a high Bioaccumulation Factor(BF) of 4.04 and a low Translocation Factor(TF) of 0.01, suggesting more Cu accumulation in the roots (4590.22 ± 385.66 µg g(-1) Cu). Noteworthy was the Cu concentration in the rhizome which was also high (3539.44 ± 1696.35 µg g(-1) Cu). SEM/EDX analyses of the Cu content in the roots indicated high elemental %Cu in the xylem (6.95%) than in the cortex (2.68%). The high Cu content in the roots and rhizomes and the localization of Cu in the xylem manifested a potential utilization of the fern as a metallophyte for rhizofiltration and phytostabilization.

    Toxoplasmosis is caused by Toxoplasma gondii, which is the main causative agent of abortion in small ruminants. Goats are among the animals that are most susceptible to this protozoon, and the disease that it causes leads to significant economic losses and has implications for public health, since presence of the parasite in products of goat origin is one of the main sources of human infection. Because of the significant economic impact, there is an urgent need to study the prevalence of T. gondii infection among goats in Sertão do Cabugi, which is the largest goat-producing region in Rio Grande do Norte. In the present study, the ELISA assay was used to test 244 serum samples from nine farms, located in four different municipalities in the Sertão do Cabugi region, which is an important goat-rearing region. The results showed that the prevalence of anti-T. gondii antibodies was 47.1% and that there was a significant association between positivity and the variables of age (≥ 34 months), location (Lajes, Angicos and Afonso Bezerra) and farm (all the farms). The avidity test was applied to all the 115 ELISA-positive samples to distinguish between acute and chronic infection. One hundred and three samples (89.6%) displayed high-avidity antibodies, thus indicating that most of the animals presented chronic infection, with a consequent great impact on the development of the goat production system and a risk to human health.

    35 unrelated individuals were studied for characterization as either heterozygous or homozygous for beta-thalassemia. Molecular analysis was done by PCR/RFLP to detect the mutations most commonly associated with beta-thalassemia (β0IVS-I-1, β+IVS-I-6, and β039). In the patients who showed none of these mutations, the beta-globin genes were sequenced. Of the 31 heterozygous patients, 13 (41.9%) had the β+IVS-I-6 mutation, 15 (48.4%) the β0IVS-I-1 mutation, 2 (6.5%) the β+IVS-I-110 mutation and 1 (3.2%) the β+IVS-I-5 mutation. IVS-I-6 was detected in the four homozygotes. The mutation in codon 39, often found in previous studies in Brazil, was not detected in the present case. This is the first study aiming at identifying mutations that determine beta-thalassemia in the state of Rio Grande do Norte. PMID:21931514

  20. The use of the ERS-2 synthetic aperture radar to study the wind-driven ocean circulation in the Gulf of Tehuantepec, Mexico, during Norte events

    NASA Astrophysics Data System (ADS)

    Martinez-Diaz-de-Leon, Asdrubal

    This thesis examines whether Synthetic Aperture Radar (SAR) images can play a useful role in observing the meso-scale structures characteristic of the Gulf of Tehuantepec during `Norte' conditions, and whether a combination of nearly coincident SAR and AVHRR derived sea surface temperature images can provide new information about these physical processes occurring in the Gulf. Sets of coincident SAR and AVHRR-derived SST images are shown to illustrate different stages in the response of the Gulf of Tehuantepec to wind forcing during a `Norte' event. From the close spatial match between the thermal signature of meso-scale structures and the radar image patterns we conclude that the SAR could be used to monitor this complex air-sea interaction process even when cloud cover prevents the use of infra- red sensors. Furthermore, the SAR data have revealed much additional detail about the ocean response to wind forcing. Other fronts and current zones which showed no thermal signature have been detected. The SAR also provides a means of determining both wind speed and direction. It has not previously been practicable to measure how sharp the wind front is at the edge of the wind jet. The SAR backscatter shows that it remains extremely tight for a long way offshore, consequently imposing a strong horizontal shear to the sea surface. However, by themselves it would be harder to interpret the SAR images in relation to the Norte processes, and we conclude that the most effective use of remote sensing is to use SAR and SST images in combination. As a case study, a SAR image is selected as expressing a typical thermal front established on the west side of the wind jet during a `Norte' event to estimate the horizontal currents associated with the front by inverting the wave refraction pattern of the swell crossing the front. The horizontal currents estimated are in very good agreement with values reported in the literature. Furthermore, when these currents are used in a numerical

    Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

    The El Paso del Norte region in the United States is a region of complex topography that is the home to more than 2 million people who share the same air. A large non-ferrous smelter (primary lead-copper smelter),owned by the American Smelting and Refining Company (ASARCO), was functioning in the Rio Grande River valley on the west side of the Franklin Mountains that divide the city of El Paso and across the river from Juarez, Mexico’s largest city on the United States border. During the more than 100 years of operation, beginning in 1887, the ASARCO smelter emissions considerably deteriorated the already complex environmental condition on the US-Mexican border. In order to identify the sources and patterns of heavy metal dispersion, we used an attic dust analyses approach which has not been previously been applied in this area. Undisturbed attic dust can provide an integrated history of atmospheric loading of particulates emanating from geological, biological and anthropogenic sources and can help to reconstruct the air pollution history on a local scale. We sampled attic dust and dust from undisturbed surfaces in 15 buildings of varying ages from three neighborhoods in the cities of El Paso and Juarez. The dust samples and samples of unpolluted buried soil horizons in the area were extracted with aqua regia and analyzed by ICP-AES and ICP-MS. Enrichment ratios (ER) were calculated by dividing the concentration of a trace metal in the attic dust by the mean concentration of the same element in the buried soil horizons. Mean ER for Pb were 263.3, 95.4, and 70.2 for dust collected in a neighborhood near the smelter, downtown Juarez, and an El Paso neighborhood on the other side of the Franklin Mountains from the smelter. Greater ER for As, Cd, Zn, Sb, and Cu followed the same trends, by neighborhood, noted for Pb. In addition, dust collected from attics surfaces (pipes, ducts, storage containers) post-dating smelter disclosure had lower ER for the trace metals

    The region situated where the borders of Mexico, Texas and New Mexico meet is known as 'Paso del Norte'. The Paso del Norte Collaborative was formed to study the seroprevalence of select pathogens and associated risk behaviors among injection drug users (IDUs) in the region. Respondent-driven sampling (RDS) was used: 459 IDU participants included 204 from Mexico; 155 from Texas; and 100 from New Mexico. Each of the three sites used a standardized questionnaire that was verbally administered and testing was performed for select bloodborne infections. Participants were mostly male (87.4%) and Hispanic/Latino (84.7%) whose median age was 38. In Mexico, Texas and New Mexico, respectively: hepatitis B virus (HBV) was seen in 88.3%, 48.6% and 59.6% of participants; hepatitis C virus (HCV) in 98.7%, 76.4% and 80.0%; human immunodeficiency virus (HIV) in 2.1%, 10.0% and 1.0%; and syphilis in 4.0%, 9.9% and 3.0%. Heroin was the drug injected most often. More IDUs in New Mexico were aware of and used needle exchange programs compared with Texas and Mexico. There was mixed success using RDS: it was more successfully applied after establishing good working relationships with IDU populations. Study findings included similarities and distinctions between the three sites that will be used to inform prevention interventions.

  5. Rio Maria granodiorite and associated rocks of Ourilândia do Norte - Carajás province: Petrography, geochemistry and implications for sanukitoid petrogenesis

    Ourilândia do Norte rocks are located near Rio Maria-Carajás domains boundary and are associated to Rio Maria Mesoarchean sanukitoid. Two groups were defined on the basis of geochemistry: (i) quartz-monzodiorites and granitoids (tonalite and granodiorite) which match to the sanukitoid (stricto sensu); and (ii) enclaves and (quartz) diorites that do not. Despite this, these rocks are spatially and temporally associated and they develop microstructures under three dynamic recrystallization regimes: (i) bulging recrystallization (300-700 °C); (ii) subgrain rotation recrystallization (<700 °C); (iii) grain boundary migration recrystallization (>600 °C). Furthermore, they belong to medium to high potassium calc-alkaline series, being magnesian and mainly metaluminous. The Mg#, Cr and Ni abundances point out an ultramafic mantle source. Variation of LILE, Nb/Y, (La/Yb)N and Sr/Y contents indicate a metasomatized mantle by two independent agents, namely TTG-like melt and aqueous fluids, at different depths. In this way, quartz-monzodiorites and granitoids were derived from fractionation of a mafic magma, whose source is a TTG-metasomatized mantle, at greater depths, while enclaves and (quartz) diorites were generated from a fluid-metasomatized mantle, at shallower depths. The close spatial and temporal association of rocks with sanukitoid (quartz-monzodiorites and granitoids) and BADR (enclaves and (quartz) diorites) signature suggest that Ourilândia do Norte granitoids were generated in close spatial and temporal association with active subduction.

  6. El destino del asteroide Albert (719)

    NASA Astrophysics Data System (ADS)

    Orellana, R. B.; Melita, M. D.; Brunini, A.

    Albert is the only numbered asteroid that remains lost at present. This object has been discovered while it was making a close apporach to the Earth by Johann Palisa in the Imperial Observatory of Vienna. According to the standard procedure of the time, a number was assigned to it shortly after a preliminar orbit has been obtained and it was named after a great benefactor of Imperial Observatory, Baron Albert von Rothschild. In this work we analyze why this body could not be recovered in its subsequent approaches to the Earth. Basicaly the cause of the loss can be summarized as follows. Given the high absolute magnitude of the object it can only be observed when it is close to the Earth. But naturally, at the close approches, the uncertanty in the position in the celestial sphere is the greatest due to a parallax effect. We have estimated the uncertanty in R.A. and declination by the non-linear propagation of the initial obervational uncertanty. We have determined that, when the aparent magnitude was low enough to observe the object with the instruments available at the time, the uncertainty region exceeded noticeably the region where it was searched. Regarding its possible recovery at present, the uncertainty in its position practicaly covers the whole sky. Nevertheless, the plane of the orbit is bounded in a narrow strip for a considerable length of time, which makes its recovery posible in old plates. The causes of the loss of Albert (719) are common to all NEO's, which is distintive about it is that it was numbered after just a few obervations, while at present the standard procedure requires that the orbit should be very well established before a denomination is given. Given the almost imposibility of its systematic recovery, in the future Albert (719) might be the first asteroid whose denomination is reassigned to another object.

  7. Spatial and Temporal Variations in Streamflow and Dissolved Solids in the Rio Grande from Del Norte, Colorado, to El Paso, Texas, 1993-95

    Data collected as part of the Rio Grande Valley National Water Quality Assessment Program were used to evaluate spatial and temporal variations in streamflow and the concentration of dissolved solids at selected sites on the Rio Grande from Del Norte, Colorado, to El Paso, Texas, for the period of April 1993 to September 1995. Dissolved solids loads, which were estimated by a multivariate linear regression model (ESTIMATOR2000), are also presented and discussed. Spatial and temporal variations in streamflow, dissolved solids concentrations, and dissolved solids loads were used to evaluate how surface-water and ground-water inflows to and outflows from the Rio Grande affect dissolved solids along the river. Streamflow decreases from Del Norte, Colorado, to the mouth of the Conejos River because of diversions for irrigation. Streamflow increases from the mouth of the Conejos River to Otowi Bridge because of surface-water inflows (from the Conejos River, the Chama River, and other tributaries) and ground-water inflow in northern New Mexico. Streamflow decreases downstream from Otowi Bridge because outflows (due to agricultural use, leakage to ground water, and evapo-transpiration) are greater than inflows. Dissolved solids concentrations generally increase in the downstream direction; however, dissolved solids concentrations decrease between the mouth of the Conejos River and Otowi Bridge due to surface-water inflows from the Conejos and the Chama Rivers and ground-water inflows in northern New Mexico. In several reaches of the Rio Grande, decreasing streamflow and increasing dissolved solids loads indicate the presence of inflows with large dissolved solids concentrations (relative to those of the Rio Grande immediately upstream from that inflow); this occurs (1) between Del Norte, Colorado, and the mouth of Trinchera Creek, near Lasauses, Colorado (2) between Otowi Bridge and San Marcial, New Mexico, and (3) between Leasburg, New Mexico, and El Paso, Texas

    For more than 40 y, there has been an active discussion over the presence and economic importance of maize (Zea mays) during the Late Archaic period (3000-1800 B.C.) in ancient Peru. The evidence for Late Archaic maize has been limited, leading to the interpretation that it was present but used primarily for ceremonial purposes. Archaeological testing at a number of sites in the Norte Chico region of the north central coast provides a broad range of empirical data on the production, processing, and consumption of maize. New data drawn from coprolites, pollen records, and stone tool residues, combined with 126 radiocarbon dates, demonstrate that maize was widely grown, intensively processed, and constituted a primary component of the diet throughout the period from 3000 to 1800 B.C.

    In this study, we determined the biologic activity of dichloromethane-extracted particulate matter < 10 micro m in aerodynamic diameter (PM10) obtained from filters at three sites in the Paso del Norte airshed, which includes El Paso, Texas, USA; Juarez, Chihuahua, Mexico, and Sunland Park, New Mexico, USA. The extracts were rich in polycyclic aromatic hydrocarbons (PAHs) and had significant biologic activity, measured using two in vitro assay systems: ethoxyresorufin-(O-deethylase (EROD) induction and the aryl hydrocarbon-receptor luciferase reporter system. In most cases, both EROD (5.25 pmol/min/mg protein) and luciferase activities (994 relative light units/mg) were highest in extracts from the Advance site located in an industrial neighborhood in Juarez. These values represented 58% and 55%, respectively, of induction associated with 1 micro M ss-naphthoflavone exposures. In contrast, little activity was observed at the Northeast Clinic site in El Paso, the reference site. In most cases, luciferase and EROD activity from extracts collected from the Tillman Health Center site, situated in downtown El Paso, fell between those observed at the other two sites. Overall, a statistically significant correlation existed between PM10 and EROD and luciferase activities. Chemical analysis of extracts collected from the Advance site demonstrated that concentrations of most PAHs were higher than those reported in most other metropolitan areas in the United States. Calculations made with these data suggest a cancer risk of 5-12 cases per 100,000 people. This risk estimate, as well as comparisons with the work of other investigators, raises concern regarding the potential for adverse health effects to the residents of this airshed. Further work is needed to understand the sources, exposure, and effects of PM10 and particulate organic material in the Paso del Norte airshed. PMID:12896850

  11. Reconstructing the annual mass balance of the Echaurren Norte glacier (Central Andes, 33.5° S) using local and regional hydroclimatic data

    Despite the great number and variety of glaciers in southern South America, in situ glacier mass-balance records are extremely scarce and glacier-climate relationships are still poorly understood in this region. Here we use the longest (> 35 years) and most complete in situ mass-balance record, available for the Echaurren Norte glacier (ECH) in the Andes at ˜ 33.5° S, to develop a minimal glacier surface mass-balance model that relies on nearby monthly precipitation and air temperature data as forcing. This basic model is able to explain 78 % of the variance in the annual glacier mass-balance record over the 1978-2013 calibration period. An attribution assessment identified precipitation variability as the dominant forcing modulating annual mass balances at ECH, with temperature variations likely playing a secondary role. A regionally averaged series of mean annual streamflow records from both sides of the Andes between ˜ 30 and 37° S is then used to estimate, through simple linear regression, this glacier's annual mass-balance variations since 1909. The reconstruction model captures 68 % of the observed glacier mass-balance variability and shows three periods of sustained positive mass balances embedded in an overall negative trend over the past 105 years. The three periods of sustained positive mass balances (centered in the 1920s-1930s, in the 1980s and in the first decade of the 21st century) coincide with several documented glacier advances in this region. Similar trends observed in other shorter glacier mass-balance series suggest that the Echaurren Norte glacier reconstruction is representative of larger-scale conditions and could be useful for more detailed glaciological, hydrological and climatological assessments in this portion of the Andes.

    A brief discussión on "the social" approach in nutritional research is presented. The relevance that socioeconomic factors have acquired in recent years for this type of studies, is also discussed. The main purpose of our communication was to identify and validate some socioeconomic and environmental indicators and their association with the nutritional status of preschool children in a Mexican indigenous community (Sierra Norte de Puebla). A total of 89 children below five years of age were studied and classified according to their nutritional status. A socioeconomic questionnaire was applied to their parents. Results revealed ample correlation between the degree of malnutrition of the preschool child and the following indicators: housing conditions, father's main occupation, land tenure, income, etc. It is argued that the analysis of these indicators is relevant, emphasizing the importance that the combination of anthropometrical, food consumption and socioeconomic data have for detecting population groups vulnerable to malnutrition. The obtention of these indicators is therefore highly recommended, but should not imply great obstacles; on the contrary, they should be highly sensitive and easy to detect.

    Urban increase of visceral leishmaniasis (VL) in Brazil is associated with the adaptation of its vector, Lutzomyia longipalpis, to environments modified by humans. The present study reports the results of an entomological monitoring of L. longipalpis and the effect of environmental variables on its population density. Sandflies were captured in the municipality of Mossoró, State of Rio Grande do Norte, Northeastern Brazil, from January 2005 to December 2006. Two CDC light traps were placed monthly for four consecutive nights in the peridomicile of selected households. Data analysis was based on the chi-square test and linear regression. A total of 2,087 sandflies were captured, 99.86% of which were L. longipalpis. A higher proportion of females were captured (p < 0.05). Monthly analysis of the variables temperature, relative humidity and rainfall did not show a significant influence on population density. However, there were seasonal differences: approximately 70% of sand flies were captured during the rainy season (p < 0.05). The predominant species, L. longipalpis, is present in substantial number, representing a public health risk. Therefore, because of higher prevalence during the rainy season, we recommend intensified VL control measures before and during this season to reduce the risk of disease transmission.

    AbstractA total of 2,431 Triatoma brasiliensis were collected from 39 populations of Paraíba (PB) and Rio Grande do Norte (RN) states, Brazil. In PB, Trypanosoma cruzi infection was not detected in either peridomestic or domestic vector populations. In contrast, in RN, T. brasiliensis was detected with high parasite prevalence in these ecotopes (30.7-40.0%). Moreover, peridomicile insect population densities were more than double the average densities of all other settings evaluated (19.17 versus < 8.94 triatomine/man-hour). Genotyped parasites evidenced a mix of T. cruzi lineages circulating in both peridomestic and sylvatic populations. Although vector control efforts have dramatically decreased Chagas disease transmission to humans, recent outbreaks have been detected in four municipalities of RN state. Our results clearly evidence a worrisome proximity between infected vectors and humans in RN. Indeed, finding of infected T. brasiliensis inside homes is routinely recorded by local vector control surveillance staff around the outbreak area, challenging the current and conventional view that vector transmissions are controlled in northeastern Brazil. This scenario calls for strengthening vector control surveillance and interventions to prevent further Chagas transmission, especially in RN State.

    The City of Las Cruces is concerned about water quality in a reach of the Rio Grande that receives outfall from the City of Las Cruces wastewater-treatment plant. Water-quality samples were collected from the Rio Grande at Picacho Bridge near Las Cruces, New Mexico; from the sampling site at the City of Las Cruces wastewater-treatment plant; and from the Rio Grande at Calle del Norte Bridge near Mesilla, New Mexico. The samples were collected on 12 days from August 6, 1996, to February 28, 1997, and were analyzed for a suite of dissolved and total constituents including trace metals. Instantaneous stream discharge was measured concurrently with collection of the Rio Grande samples. At the wastewater- treatment plant, the City of Las Cruces provided instantaneous discharge rates concurrent with sampling. Quality-control measures used in this study to ensure analytical accuracy included replicate sampling, replicate analysis of split samples, ambient blanks, equipment blanks, and analysis of standard reference water samples.

    We collected sample data on radon concentrations concurrently in the air, water, and soil in the northern part of the Texas-Mexico border (both sides) popularly known as Paso Del Norte. These field data were used to statistically correlate relative contributions of yard soil, tap water, location, and house features to concentrations of radon indoors. Indoor air radon concentrations in some homes were up to nine-fold the limit recommended by the US Environmental Protection Agency (USEPA). Concentrations of radon in tap water were up to nearly three-fold the recommended limit. Apartments and manufactured homes had generally greater concentrations of indoor radon. Statistically significant associations were indicated between indoor radon air levels and radon in the soil (P < 0.001); radon in the water and radium in water (P = 0.016); radon air levels and apartment living (P = 0.010); and mobile homes vs. wood, brick, and stucco construction (P = 0.016). Radon soil gas, apartment living, and the aluminum plank wall environment of mobile homes were associated with elevated indoor radon in the homes studied. Physician's attention is invited to the potential nontrivial risk from radon, as it becomes trapped inside enclosed structures. This article is intended to serve as a resource for primary care physicians who want to better understand the distribution and contributing factors for indoor radon. The Surgeon General recommends every US home be tested for radon as of January 13, 2005.

    The gonad development and reproductive aspects of Hemiramphus brasiliensis from the coastal waters of Rio Grande do Norte, Brazil were verified. This paper presents data on the length-weight relationship, sex ratio, length at first sexual maturity, gonad development, reproductive period and fecundity of H. brasiliensis. Females of this species predominated in the sampled population and were larger in size than the males. The length at the first sexual maturation of males was 20.8 cm and that of females was 21.5 cm. The macroscopic characteristics of the gonads indicated four maturation stages. Histological studies of gonads of H. brasiliensis showed six phases of oocyte development and four phases of spermatocyte development. The batch fecundity of this species is 1153 (± 258.22) oocytes for 50 g body weight of female. The microscopic characteristics of gonad development indicate that H. brasiliensis is a multiple spawner, with active reproductive period during the months of January to June and October. The reproductive period of this species is independent of the rainy period of the region.

    This article investigates the severity and functional independence of hemiplegics patients' post-acute stroke by means of a multidisciplinary clinical staff. It is a descriptive study composed by 40 hemiplegics attended at the four largest physiotherapy public services in Natal, Rio Grande do Norte State. The methods used were an evaluation form, Functional Independence Measure and NIHSS. The results showed a sample predominantly female (55%), stroke ischemic (90%), right brain hemisphere (52.5%) and Hypertension Risk Factor (90%). The mean of clinical severity and functional independence was 13.32±4.7 and 54.6±17.15 respectively. There was no significant difference between the mean of functionality about stroke side (pvalue = 0.66). There is a significant relation between clinical severity and functional independence (r = -0.45 pvalue=0.003). It can be concluded that the level of clinical severity and functional dependence of stroke patients that make use of public physiotherapy services is significant and show the necessity, beyond the classic treatment, to be encouraged preventive educational actions to improve knowledge of this population.

    As part of an institutional program sponsored by the Centre for Teaching Excellence at the Universidad del Norte, Barranquilla, Colombia, we developed an educational research study on two sessions of human anatomy in which we combined team-based learning (TBL) and the use of iPads. Study data included the TBL, assessments applied during the course, student's grades on mid-term examinations and students' perceptions of their experiences. Students reported a positive attitude toward the use of the TBL sessions, and the results showed a significant improvement in their learning between the first and second sessions. Significantly positive correlations (P < 0.05) were obtained between (a) the individual students' readiness test performance 1 and mid-term examination 1, (b) the individual readiness test performances from Session 1 to Session 2, and (c) the group readiness test performances from the first and second sessions. These results point to positive learning experiences for these students. Analyses of the students' reflections on their activities also pointed toward future challenges.

    Miocene oil reservoirs in the 30-km{sup 2} Mioceno Norte area are estimated to have a recovery efficiency of only 27 percent at the end of primary recovery operations at the current 40-acre well spacing. Although this area has produced oil since the 1930s, appreciable volumes of oil remain in multiple, poorly contacted reservoir compartments. Strategic development of these compartments could improve ultimate recovery up to an additional 15 to 20 percent of the original oil in place. Multiple Miocene regressive-transgressive episodes in the Maracaibo Basin resulted in a complex reservoir architecture. Basal Miocene fluvial deposits, deposited during a forced regression, are overlain by shelf and transgressive barrier-island deposits of a highstand systems tract. Episodes of upper Miocene fluvial and lacustrine-fill deposits, bounded by continuous paleosol marker beds, record climate changes or intermittent tectonic activity resulting in reorganization of dip-dispersal systems. We used an integrated reservoir-characterization program incorporating structural, stratigraphic, seismic, palynological, petrophysical, petrographic, petroleum-engineering, and volumetric analyses to target areas for strategic oil recovery. Remaining oil is inferred to occur mainly in narrow (less than 2000 in wide), uncontacted or poorly contacted fluvial-and distributary-channel sandstones commonly projected between existing well spacing. Additional remaining oil exists in tidal-channel and backbarrier areas where washover-fan sandstones pinch out into muddy lagoonal-fill deposits.

    El artículo examina el estatuto epistemológico de la bioética como disciplina académica. El autor sostiene que el estatuto epistemológico de un discurso lo determina la pregunta fundamental que se plantea y la respuesta que se busca, focos integradores del discurso. En el caso de la bioética, la pregunta fundamental es de índole moral. La bioética es pues una disciplina ética que tiene su hogar epistemológico en la filosofía. El autor también defiende el concepto de “éticas aplicadas”. Sugiere finalmente que el método de la bioética, sobre todo la que se hace desde nuestras latitudes, debería adoptar el círculo hermenéutico como metodología para su filosofar. PMID:20463860

    Snowmelt is the primary source of surface water in the western United States and many other regions on Earth. Climate warming is forecast to impact the amount of precipitation that falls as snow and forms the mountain snowpack. Climate change induced alterations to snowpack translate to changes in snowpack magnitude, the timing of snowmelt, and changes in snowmelt rate. We ask how these perturbations may impact how snowmelt is partitioned between evapotranspiration (ET) and runoff (R) at Como Creek, a snowmelt dominated catchment on the Colorado Front Range. Como Creek is a 4.5 km2 headwater catchment spanning 2900-3560 m and is part of the Niwot Ridge Long Term Ecological Research Station and the Boulder Creek Critical Zone Observatory. We use observations of snow water equivalent (SWE), ET, and precipitation (P) from Niwot Ridge, CO, and discharge from Como Creek to explore relationships between snowpack dynamics and snowmelt partitioning. Measurements of ET are collected adjacent to Como Creek at the Niwot Ridge Ameriflux site and are assumed representative of the hydrologic fluxes in Como Creek. Analyses from point data show that years with higher peak SWE/P ratios partition proportionally more snowmelt to ET (pValue: 0.045). For example, water year (WY) 2005 has a peak SWE/P ratio of 0.49 and a growing season ET normalized by WY precipitation (ET/P) ratio of 0.48 while WY 2008 has a peak SWE/P ratio of 0.83 and an ET/P ratio of 0.82. Observations also show that years that experience later peak SWE (DOY=142) partition proportionally less snowmelt into ET (ET/P=0.42) compared to years that experience earlier peak SWE (DOY=86) and partition proportionally more snowmelt to ET (ET/P=0.56). Further point analyses also suggest that more rapid snowmelt results in proportionally less snowmelt partitioned to ET and more partitioned to runoff. To explore the underlying processes responsible for these relationships at the catchment scale we use the Regional Hydro

    refers to the coastal zone between the Amapa Grande River and Araguari River, including Maraca Island and the Oriental lacustrine Belt. Westward the island, at least three paleolevels of clays with roots in life position suggests regressive/transgressive events. Extraordinaty paleodrainage network beginnig at the continent and recognized at the insular portion suggests links with the paleochannels found at the continental shelf. The Oriental Belt of lakes is located close to the coastline, at Cabo Norte. It main feature is a mud lump approximately 10 Km ratio, well recognized at the remote sensing. It shows similar evolutionary processes with Araguari River, dating from XIX century, when this river had two mouths defined by the Carpori Island. The reasons of the deactivation are still unknowed, but, this rapid morphological evolution indicates short time colmatation processes that can be linked to tectonic regional processes. On the other hand, the Cabo Norte feature consolidation may impose changes in the sedimentation processes yielding space reduction over the coastal plain accumulation, diminishing of the solid and liquid fluvial discharge and promoting the availability of the local sediment transport over the littoral. The investigation of these processes requires an integrated coastal plain-continental shelf morphological study applying adequate techniques for modification studies and dating ages over short geological time frame, in century scale level.

    There is a high incidence of leprosy in the municipality of Mossor6, Rio Grande do Norte state, where the detection coefficient has risen from 2.78/10,000 population in 1998 to 5.14 in 2004. While cases have been registered throughout the urban area, the disease is concentrated in select neighbourhoods. This study was undertaken using Geographical Information System (GIS) with the objective of defining low-cost, effective strategies to control leprosy. The land registry map of the city, Ikonos satellite images and the SINAN (National Morbidity Notification Information System) database were used as the cartographical basis for the study. The sample for the leprosy mapping was drawn from the 358 new cases of the disease diagnosed in the municipality between 1998 and 2002. The houses of 281 patients were located (78.5% of the total) and their addresses geo-referenced using a GPS handheld device. Subsequently, geographical analysis was carried out using ArcView 9.0 software showing predominant concentration of cases in the neighbourhoods of Barrocas, Santo Antônio, Bom Jardim and Paredões. This mapping served as the basis for four active case finding campaigns conducted in the most highly concentrated areas between March and September of 2005. Campaigns guided by spatial analysis led to the diagnosis of 104 new cases of the disease (50% of the total number of new cases detected in the municipality in 2005). The use of GIS in leprosy diagnosis has shown to be extremely effective, providing a clear visual understanding of the distribution of the disease in the municipality, which results in targeted interventions and important cost reductions in leprosy control activities.

    To understand the meanings of pre-eclampsia for pregnant and postpartum women and health-care professionals. a word-association test and semi-structured interviews. A maternity hospital located in Natal, Rio Grande do Norte, Brazil that serves pregnant and postpartum women considered to be at high risk. 51 Pregnant women, 10 postpartum women and 87 health-care professionals completed a word-association test; 18 pregnant women, two postpartum women and 20 health-care professionals for the interviews. Thematic categories based on the word-association test and the interviews were created to help the data analysis. χ(2) test was used to compare the categories raised by both groups in the word-association test to determine the association between the frequencies of these categories. The meanings of pre-eclampsia to pregnant and postpartum women were fear, risk, care and lack of information. To the health-care professionals, the meanings were care, fear, risk, high blood pressure, oedema and proteinuria. The frequencies of the categories 'fear', 'care' and 'risk' were statistically different (χ(2) = 31.84, 14.5, 38.19, respectively; df = 2, p < 0.001) between the group of pregnant and postpartum women and the group of health-care professionals. For the first group, the most significant meanings were fear and risk, compared with care for the second group. The analysis of the interviews confirmed and deepened the results of the word-association test, and also demonstrated that the pregnant and postpartum women had no information about pre-eclampsia. There is a gap between how women and health professionals view their experiences of pre-eclampsia. A warm welcome to the health-care facility, with clear explanations about the disease and the procedures to be performed during the visits and hospitalisation would be important aspects for the physical and mental well-being of pregnant and postpartum women.

    This research describes the methods involved in the mapping of different high value crops in Agusan del Norte Philippines using LiDAR. This project is part of the Phil-LiDAR 2 Program which aims to conduct a nationwide resource assessment using LiDAR. Because of the high resolution data involved, the methodology described here utilizes object-based image analysis and the use of optimal features from LiDAR data and Orthophoto. Object-based classification was primarily done by developing rule-sets in eCognition. Several features from the LiDAR data and Orthophotos were used in the development of rule-sets for classification. Generally, classes of objects can't be separated by simple thresholds from different features making it difficult to develop a rule-set. To resolve this problem, the image-objects were subjected to Support Vector Machine learning. SVMs have gained popularity because of their ability to generalize well given a limited number of training samples. However, SVMs also suffer from parameter assignment issues that can significantly affect the classification results. More specifically, the regularization parameter C in linear SVM has to be optimized through cross validation to increase the overall accuracy. After performing the segmentation in eCognition, the optimization procedure as well as the extraction of the equations of the hyper-planes was done in Matlab. The learned hyper-planes separating one class from another in the multi-dimensional feature-space can be thought of as super-features which were then used in developing the classifier rule set in eCognition. In this study, we report an overall classification accuracy of greater than 90% in different areas.

    Due to its peculiar geographical and morphological characteristics, Lake Como (Northern Italy) represents an interesting study-case for investigating the sub-basin scale circulation of persistent organic pollutants (POPs) that, despite being banned since the 1970s, have reached surprisingly high concentrations in some southern alpine lakes as a consequence of their release from melting glaciers in recent years. In particular, the Como Bay, which is located in the city of Como, seems noteworthy because its waters have a longer residence time than the other areas of the lake. The analyses of the historical concentration of PCBs, pp′DDT and its metabolites in a sediment core sampled from the Como Bay covering a time-period from their ban to recent times, showed that the DDTs have never experienced a significant (p < 0.05) decrease over time, with concentrations of the most abundant homologue, pp′DDE, ranging from 27 to 75 ng g(-1) d.w. Conversely PCBs significantly (p < 0.05) decreased towards recent times, reaching concentrations around 80 ng g(-1) d.w. The contribution of high altitude and local sources was recorded also in the food web: both zooplankton and the zooplanktivorous fish agone were mainly contaminated by pp′DDE (81.4 ng g(-1) w.w. and 534.6 ng g(-1) w.w. respectively) and by the PCB metabolite hexa-CB (449.7 ng g(-1) w.w. and 1672.1 ng g(-1) w.w. respectively). The DDT concentrations in the agone (sampled during the years 2006–2009) never exceeded the limits for human consumption in Italy, while concentrations of six selected PCBs exceeded human health advisory recommendations in one of the fish samples analysed, when it was approximately two times higher than the recommended value of 125 ng g(-1) w.w.

    The Ediacaran-Cambrian plutonic activity is one of the most important geological features of the Rio Grande do Norte Domain (Borborema Province, NE Brazil). It is represented by several batholiths, stocks and dykes. Based on the petrographic, geochemical and geochronological characteristic of different rocks, this plutonic activity can be grouped in six separate suites: shoshonitic (Shos), porphyritic high-K calc-alkaline (PHKCalcAlk), equigranular high K calc-alkaline (EHKCalcAlk), calc-alkaline (CalcAlk), alkaline (Alk) and charnockitic alkaline (ChAlk). Geochemically, the Shos, CalcAlk and Alk suites are differentiated from the others, while ChAlc can be distinguished from the others in some diagrams. The greatest difficulty lies in distinguishing between the chemically similar PHKCalcAlk and EHKCalcAlk. To this end, existing geochronological data as well as related petrographic and textural field aspects may be used to distinguish the two mentioned suites (PHKCalcAlk and EHKCalcAlk). Petrographically, the Shos suite has composition between gabbro/diorite and quartz monzonite. Monzogranites (with subordinate granodiorites and quartz monzonites) predominate in both PHKCalcAlk and EHKCalcAlk. Calc is composed of granodiorites to tonalites. Alc is formed by alkali feldspar granites (with subordinate alkali feldspar quartz syenites and syenogranites), whereas ChAlc has quartz mangerites and charnockites. The suites were emplaced between the Ediacaran (635-541 Ma) and Cambrian (541-485 Ma), predominantly in the Ediacaran, based on 34 U-Pb datings (zircon, titanite, monazite and columbite-tantalite), 17 Rb-Sr (whole rock) and 1 Sm-Nd (total rock and mineral) internal isochrons. The Shos suite has U-Pb ages varying from 599 ± 16 (Poço Verde pluton) to 579 ± 7 (Acari and São João do Sabugi plutons), slightly older than those of the PHKCalcAlk suite, which ranges between 591 ± 4 Ma (Totoró pluton) and 544 ± 7 Ma (São José de Espinharas pluton).

    Cartographic cultural heritage preserved in worldwide archives is often stored in the original paper version only, thus restricting both the chances of utilization and the range of possible users. The Web C.A.R.T.E. system addressed this issue with regard to the precious cadastral maps preserved at the State Archive of Como. Aim of the project was to improve the visibility and accessibility of this heritage using the latest free and open source tools for processing, cataloguing and web publishing the maps. The resulting architecture should therefore assist the State Archive of Como in managing its cartographic contents. After a pre-processing consisting of digitization and georeferencing steps, maps were provided with metadata, compiled according to the current Italian standards and managed through an ad hoc version of the GeoNetwork Opensource geocatalog software. A dedicated MapFish-based webGIS client, with an optimized version also for mobile platforms, was built for maps publication and 2D navigation. A module for 3D visualization of cadastral maps was finally developed using the NASA World Wind Virtual Globe. Thanks to a temporal slidebar, time was also included in the system producing a 4D Graphical User Interface. The overall architecture was totally built with free and open source software and allows a direct and intuitive consultation of historical maps. Besides the notable advantage of keeping original paper maps intact, the system greatly simplifies the work of the State Archive of Como common users and together widens the same range of users thanks to the modernization of map consultation tools.

    A significant portion of the population in the Philippines consists of indigenous people (IP) groups, approximately 9% or 8.1 million. Data on the health status of these groups are very limited including the status of soil-transmitted helminth (STH) infections. Provision of such data will be of great importance in the formulation of policy on control and prevention of these diseases in this group. This study was conducted in selected villages/barangays in the municipalities of Carmen, Kapalong, San Isidro and Sto. Tomas in the Province of Davao del Norte in Southern Mindanao, Philippines. Parasitologic assessment was performed using Kato-Katz to qualify and quantify STH infections, while nutritional status assessment was based on hemoglobin determination and on nutritional status indicators, i.e., weight-for-age (WFA), height-for-age (HFA), and body mass index (BMI) for age derived from anthropometric measurements. A total of 572 school children participated in the survey, 264 (46.2%) of whom belonged to a specific IP group. Results showed that 34.1% of the school children had at least one STH infection while 5.9% had heavy intensity infections. Cumulative prevalence in IP school children was significantly higher than in non-IP children with rates at 39.0% and 29.9%, respectively (P = 0.021). Overall prevalence of school children with below normal WFA was 29.9%, while prevalence of those with below normal HFA and BMI for age was 42.8% and 14.9%, respectively. Of those examined, 8.3% had below normal hemoglobin levels. There was no significant difference observed between the nutritional status parameters of IP and non-IP school children. The parasitologic parameters reported in this study signify the need to pay more attention to IP children who are at higher risk of morbidity due to helminth infections. Access of IP communities to quality health services, which include mass drug administration (MDA) and health education on a regular basis, must be ensured. Further

    Soil moisture is an important component of the hydrological cycle. Climate variability patterns, such as the Pacific Decadal Oscillation (PDO), El Niño Southern Oscillation (ENSO), and Atlantic Multidecadal Oscillation (AMO) are determining factors on surface water availability and soil moisture. Understanding this complex relationship and the phase and lag times between climate events and soil moisture variability is important for agricultural management and water planning. In this study we look at the effect of these climate teleconnection patterns on the soil moisture across the Rio Grande/Río Bravo del Norte basin. The basin is transboundary between the US and Mexico and has a varied climatology - ranging from snow dominated in its headwaters in Colorado, to an arid and semi-arid region in its middle reach and a tropical climate in the southern section before it discharges into the Gulf of Mexico. Agricultural activities in the US and in northern Mexico are highly dependent on the Rio Grande and are extremely vulnerable to climate extremes. The treaty between the two countries does not address climate related events. The soil moisture is generated using the community NOAH land surface model (LSM). The LSM is a 1-D column model that runs in coupled or uncoupled mode, and it simulates soil moisture, soil temperature, skin temperature, snowpack depth, snow water equivalent, canopy water content, and energy flux and water flux of the surface energy and water balance. The North American Land Data Assimilation Scheme 2 (NLDAS2) is used to drive the model. The model is run for the period 1979 to 2009. The soil moisture output is validated against measured values from the different Soil Climate Analysis Network (SCAN) sites within the basin. The spatial and temporal variability of the modeled soil moisture is then analyzed using marginal entropy to investigate monthly, seasonal, and annual variability. Wavelet transform is used to determine the relation, phase

    The objective of this study was to assess the environmental changes with respect to the concentration of heavy metals in the sediment contained a stretch of the River Apodi-Mossoró (Rio Grande do Norte State, Brazil), considering changes in land use and soil. The sediment samples were collected at 30 points in the bed Apodi- Mossoró River in a section with features urban-rural town of Mossoró. The concentration of heavy metals in the sediment was determined using composite samples of surface sediments from the bottom with a depth of 20 cm, according to the methodology of APHAAWWA-WPCF (1998), where he subsequently held to determine the presence and quantity of metal concentration total by the technique of atomic absorption spectrometry, and analyzed the following heavy metals: aluminum(Al), cádmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn). Data were analyzed using statistical and geostatistical. The geostatistical analysiswas performed by the construction of experimental semivariogramas self-assessment and adjustment by using the technique of Jack-kinifing. The elemento Cd was absent in the samples, which reduces the possibility of environmental contamination events. The average concentrations of the elements under study are within the limits proposed by the environmental legislation (National Environmental Council). However, for the elements Fe, Al and Mn no threshold values, because these are associated with the rocky material of geochemical origin. The elemento Fe had the highest range of values than the other, and all elements except for Zn and Cd showed the presence of outliers, suggesting the possibility that these points are listed as points liable to contribution by human activities. It was verified the presence of human influence, because the elements undergo an increase of concentration values from the point 11, which is located downstream of the urban bus consolidated.

    variability of the PREDICTED to OBSERVED ozone concentrations of both BASELINE model and simulations with modified emissions assessed by the sensitivity analysis. All simulations were found to vary within acceptable ranges of these two criteria variables. Simulation results indicate ozone formation in the PdN region is VOC-limited. Under VOC-limited conditions, modifications to NOx emissions do not produce a marked increase or decrease in ozone concentrations. Modifications to VOC emissions generated the highest variability in ozone concentrations. Increasing VOC emissions by 75% produced results which minimized model bias and error when comparing PREDICTED and OBSERVED ozone concentrations. Increasing VOC emissions by 75% either alone or in combination with a 75% increase in NOx emissions generated PREDICTED ozone concentrations very near to OBSERVED ozone. By evaluating the changes in ambient ozone concentrations through photochemical modeling, air quality planners may identify the most efficient or effective VOC emissions control strategies for area sources. Among the strategies to achieve emissions reductions are installation of gasoline vapor recovery systems, replacing high-pressure low-volume surface coating paint spray guns with high-volume low-pressure spray paint guns, requiring emissions control booths for surface coating operations as well as undertaking solvent management practices, requiring the sale of low VOC paint solvents in the surface-coating industry, and requiring low-VOC solvents in the dry cleaning industry. Other strategies to reduce VOC emissions include initiating Eco-Driving strategies to reduce fuel consumption from mobile sources and minimize vehicle idling at the international ports of entry by reducing bridge wait times. This dissertation depicts a tool for evaluating impacts of emissions on regional air quality by addressing the highly unresolved fugitive emissions in the Paso del Norte region. It provides a protocol for decision makers to

    Cebus flavius is a recently rediscovered species and a candidate for the 25 most endangered primate species list. It was hypothesized that the distribution of C. flavius was limited to the Atlantic Forest, while the occurrence of C. libidinosus in the Rio Grande do Norte (RN) Caatinga was inferred, given its occurrence in neighboring states. As a result of a survey in ten areas of the RN Caatinga, this paper reports on four Cebus populations, including the first occurrence of C. flavius in the Caatinga, and an expansion of the northwestern limits of distribution for the species. This C. flavius population may be a rare example of a process of geographic distribution retraction, and is probably the most endangered population of this species. New areas of occurrence of C. libidinosus are also described. Tool use sites were observed in association with reports of the presence of both capuchin species.

  18. A Geostatistical Approach to Reducing Uncertainty in Rainfall Estimates Using Terrain Characteristics: A Case Study in the Central-North Regional Water Administration of Mozambique (ARA Centro-Norte)

    Many data-sparse regions, such as southern Africa, will likely face significant changes in water resources availability and timing in the future due land use change, climate change and population growth. Improved estimates of rainfall and streamflow are necessary to improve water resources decision-making, risk management, and uncertainty quantification. In this study, we use a universal kriging framework to associate various watershed terrain characteristics with gauged rainfall data to improve the estimation of monthly rainfall fields. We focus on available gauge data because other precipitation data sources, such as satellite precipitation products, are unavailable over historic periods of interest and exhibit bias in our context of streamflow estimation. Our study area is the 185,000 sq km Central-North Regional Water Administration of Mozambique (ARA Centro-Norte), which is predominantly rural tropical savanna. We use fifty years of spatially and temporally sparse monthly rainfall observations from 316 rainfall gauges. Most of the watershed terrain characteristics we use are derived from the 90m HydroSHEDS Digital Elevation Model dataset. These include elevation, aspect, slope, distance to large water bodies, distance to ridges, and distance to watershed rainfall maximum. We quantify the importance of these characteristics for reducing uncertainty in rainfall estimates using the Bayes information criterion (BIC) approach. Future work includes using these rainfall estimates to drive the semi-distributed monthly time-step Pitman rainfall-runoff model, in order to reduce uncertainty in streamflow estimates in gauged and ungauged basins.

    The scope of the study was to analyze the prevalence and factors associated with falls among the elderly registered in a Primary Healthcare Unit (PHU) in Natal, State of Rio Grande do Norte. It involved a cross-sectional study conducted with 280 elderly individuals with data collected at the primary healthcare unit. The association between falls, recurrent falls and independent variables was assessed using bivariate analysis and Poisson regression with calculation of their respective prevalence ratios. It involved predominantly elderly females (68.2%) with mean age of 71.6 years (± 6.7), literate (54.6%), non-retired (73.5%) and sedentary (87.1%). 53.6% of the elderly recorded falls and 27.8% fell twice or more. The predictive model of falls included the female gender (PR= 1.81), osteoarticular diseases (PR = 1.71) and balance impairment (PR = 0.88), while functional mobility (PR = 0.94), fear of falling (PR = 1.21) and balance deficit disorders (PR = 0.80) constituted the definitive model of recurrent falls. A higher prevalence of single fall episodes was found and the associated factors included sociodemographic, health and physical performance variables. On the other hand, the occurrence of two or more falls were only associated with physical performance variables.

    Sand flies are insect vectors of protozoa from the genus Leishmania, causative parasites of visceral and American tegumentary leishmaniases. The present study discusses the bioecological aspects of sand fly species, transmitters of Leishmania protozoa, in different ecotopes of an Atlantic Forest Conservation Unit located in the metropolitan region of Natal, Rio Grande do Norte state, Brazil. Two monthly captures were made in 1 year, using CDC light traps, in two anthropized and two preserved environments. A total of 2936 sand flies belonging to the following ten species were captured: Evandromyia walkeri, Evandromyia evandroi, Psychodopygus wellcomei, Sciopemyia sordellii, Psathyromyia brasiliensis, Lutzomyia longipalpis, Evandromyia lenti, Psathyromyia shannoni, Nyssomyia whitmani and Nyssomyia intermedia. The most common species was E. walkeri (77.6%), followed by E. evandroi (17.5%). Forest was the site with the greatest abundance (32.4%), followed by bamboo grove (26.3%). Sand flies were generally more abundant in the rainy season and L. longipalpis, a vector species of Leishmania infantum, was adapted to anthropized environments. It was confirmed that P. wellcomei, a vector of Leishmania braziliensis in Amazônia, is a species associated with more preserved environments, and occurs only in the rainy season.

    An offshore vertical incidence reflection seismic study with simultaneous on-land wide-angle recording has been conducted, as part of the Estudio Sismico de la Corteza Ibérica Norte (ESCIN) Project, in the NW Iberian Variscan Belt, an area deeply affected by Variscan and Alpine deformation episodes. Line ESCIN-3.3 was recorded across strike of the main Variscan structures, transecting two of the zones in which the NW Iberian Massif has been subdivided. This study intends to correlate the seismic features observed in the near-vertical reflection profile with the velocity model deduced from the wide-angle data, with the well-known geological structure of the Variscan upper crust, and with some other geophysical features described on the basis of offshore and onshore experiments carried out in the area. The main results can be summarized as follows: (1) identification of two important sedimentary basins in the shallow part of the marine seismic section, related with the Mesozoic extension that gave rise to the opening of the Bay of Biscay, (2) correlation of a number of subhorizontal and west dipping intermediate depth reflections with Variscan compressional structures, (3) interpretation of a local set of strong reflections at 6 s (two-way travel time) as lower crust emplaced at an anomalous shallow level (thought to image the northward prolongation of a body with high P wave velocity and high magnetic susceptibility, described on land underneath a late Variscan antiformal structure, the Lugo Dome), and (4) recognition of two controversial highly reflective subhorizontal bands, located at 7-9 and 11-12 s, respectively. The shallowest of them appears to have a lower crustal P wave velocity and to be separated from the deepest one, probably with similar characteristics, by mantle P wave velocity material. On this basis, a duplication of the lower continental crust is inferred. The deepest of the bands could either represent the remnants of a late Paleozoic crustal

    Few historical streamflow and water-quality data are available to characterize the segment of the Rio Grande/Rio Bravo del Norte (hereinafter Rio Grande) extending from near Presidio to near Langtry, Texas. The U.S. Geological Survey, in cooperation with the National Park Service and the Texas Commission on Environmental Quality, collected water-quality and streamflow data from the Rio Grande from near Presidio to near Langtry, Texas, to characterize the streamflow gain and loss and selected constituent concentrations in a 336.3-mile reach of the Rio Grande from near Presidio to near Langtry, Texas. Streamflow was measured at 38 sites and water-quality samples were collected at 20 sites along the Rio Grande in February, March, and June 2006. Streamflow gains and losses over the course of the stream were measured indirectly by computing the differences in measured streamflow between sites along the stream. Water-quality data were collected and analyzed for salinity, dissolved solids, major ions, nutrients, trace elements, and stable isotopes. Selected properties and constituents were compared to available Texas Commission on Environmental Quality general use protection criteria or screening levels. Summary statistics of selected water-quality data were computed for each of the five designated subreaches. Streamflow gain and loss and water-quality constituent concentration were compared for each subreach, rather than the entire segment because of the temporal variation in sample collection caused by controlled releases upstream. Subreach A was determined to be a losing reach, and subreaches B, C, D, and E were determined to be gaining reaches. Compared to concentrations measured in upstream subreaches, downstream subreaches exhibited evidence of dilution of selected constituent concentrations. Subreaches A and B had measured total dissolved solids, chloride, and sulfate exceeding the Texas Commission on Environmental Quality general use protection criteria

    Se muestra que tanto la forma de los perfiles de brillo como de color observados en dos galaxias arquetípicas de tipo cD (NGC 1399 y NGC 4486) son compatibles con la presencia de poblaciones estelares bi-modales que comparten la misma distribución espacial y composición química de las familias dominantes de cúmulos globulares asociadas con ellas. El modelo resultante también predice una variación de la frecuencia específica de los cúmulos como función del radio galactocéntrico. Se discute este resultado en el contexto de una variedad de escenarios astrofísicos que intentan describir la formación de galaxias cD.

    Onchocerciasis control by vector control was instigated in southwest Burkina Faso in January 1969 by ORSTOM/OCCGE, and continued until operations were taken over by the WHO Onchocerciasis Control Programme (OCP) in February 1975, which itself ceased operations in the area in 1989 when onchocerciasis was judged to have been reduced to insignificant levels. Initially (1969-1975) vector immigration maintained unacceptably high levels of transmission, but OCP was much larger than the preceding campaign and in 1975 the Annual Transmission Potential (ATP) dropped below 100 at all sites in the Comoé river valley except Folonzo, which continued to be subject to reinvasion, along with the whole of the Léraba river valley. However, after the southern extension of the OCP in 1979, ATPs dropped below 100 everywhere in the Comoé basin (including the Léraba valley), and further dropped to insignificant levels after the western extension of the OCP in 1985. Thus transmission dropped more quickly in the Comoé river valley than the Léraba river valley (which had been subject to vector reinvasion), and this was also reflected in prevalence of microfilaraemia in the human population. After 1986 prevalence was less than 5% in all villages in the Comoé river valley (except for two, which subsequently dropped to 0% and 3.7% by 1999). However, in 2001 (12 years after the cessation of vector control) the prevalence in one village in the Comoé river valley had increased to 39.6%, and two more had increased above 5% by 2007. New epidemiological surveys in 2011 and 2012 showed that in 13 out of 30 villages in the Comoé river valley prevalence of microfilaraemia was above 5%, although this was not observed in the Léraba river valley where prevalence remained low. This is the first documented case of recrudescence of onchocerciasis in the old OCP area, and the reasons are not clear. It is possible that there has been immigration of parasites with humans or vectors from areas where

  9. The Sefwi-Comoé belt Ghana/Ivory Coast : a major crustal shear zone ?

    2010-05-01

    The Palaeoproterozoic Sefwi-Comoé region that straddles Ghana and the Ivory Coast in West Africa has been characterised as resulting from a combination of compression and simple shear during late synkinematic leucogranite intrusion. The analysis of regional geophysical datasets allows us to better define the geometry of the major lithostratigraphic packages and their structural contacts in this region. This analysis reveals a series of well defined leucogranites intrusions enveloped by high strain zones. Recent finite element modelling of two-phase aggregates has shown that we can analyse the geometry of these systems both in terms of their finite defomation and their mechanical contrast. We interpret the geometries we see in the Sefwi-Comoé region as reflecting the activity of a major crustal deformation zone which was dominated by simple shear. The comparison with the modelling suggests a finite shear strain of approximately 5 gamma, which in turn implies a lateral displacement of 400 km across the belt. Our analysis suggests that the leucogranites were already acting as more rigid bodies during the (dextral?) shearing, suggesting that their emplacement was predominantly pre-kinematic, and which has implications for their potential subsequent remobilization by gravitational forces.

  10. Remote structural monitoring of the Cathedral of Como using an optical fiber Bragg sensor system

    Whelan, Maurice P.; Albrecht, Daniel; Capsoni, Antonio

    2002-07-01

    This paper describes a prototype system being developed for on-line structural monitoring of the cathedral of Como, Italy. Monitoring is based on relative displacement and temperature measurements employing optical fibre Bragg grating transducers. System features include an edge-filter demodulation scheme with wavelength multiplexing, palmtop-based control with customised software, automated data acquisition and analysis and GSM-based data transmission via email. The system also offers the option to be solar powered, allowing it to be located in areas with limited access, such as on the cathedral roof. Initial results obtained over an eight-month demonstration period are also presented. The intention is to develop this prototype into a complete system for on-line structural monitoring of the Cathedral, offering real decision support to those responsible for its maintenance.

    Over a 6 month period during the dry season, from the end of October 2014 to the beginning of May 2015, we studied tool use behavior of previously unstudied and non-habituated savanna chimpanzees (Pan troglodytes verus) living in the Comoé National Park, Ivory Coast (CI). We analyzed all the stick tools and leaf-sponges found that the chimpanzees used to forage for ants, termites, honey, and water. We found a particular behavior to be widespread across different chimpanzee communities in the park, namely, dipping for water from tree holes using sticks with especially long brush-tip modifications, using camera traps, we recorded adults, juveniles, and infants of three communities displaying this behavior. We compared water dipping and honey dipping tools used by Comoé chimpanzees and found significant differences in the total length, diameter, and brush length of the different types of fluid-dipping tools used. We found that water dipping tools had consistently longer and thicker brush-tips than honey dipping tools. Although this behavior was observed only during the late dry season, the chimpanzees always had alternative water sources available, like pools and rivers, in which they drank without the use of a tool. It remains unclear whether the use of a tool increases efficient access to water. This is the first time that water dipping behavior with sticks has been found as a widespread and well-established behavior across different age and sex classes and communities, suggesting the possibility of cultural transmission. It is crucial that we conserve this population of chimpanzees, not only because they may represent the second largest population in the country, but also because of their unique behavioral repertoire.

    Layered transition metal sulfides (TMS) are emerging as advanced materials for energy storage and conversion applications. In this work, we report a facile and cost-effective anion exchange technique to fabricate a layered, multifaceted, free standing, ultra-thin ternary cobalt molybdenum sulfide nanosheet (Co-Mo-S NS) architecture grown on a 3D porous Ni foam substrate. The unique Co-Mo layered double hydroxides are first synthesized as precursors and consequently transformed into ultra-thin Co-Mo-S NS. When employed as an electrode for supercapacitors, the Co-Mo-S NS delivered an ultra-high specific capacitance of 2343 F g(-1) at a current density of 1 mA cm(-2) with tremendous rate capability and extraordinary cycling performance (96.6% capacitance retention after 20 000 cycles). Furthermore, assembled Co-Mo-S/nitrogen doped graphene nanosheets (NGNS) in an asymmetric supercapacitor (ASC) device delivered an excellent energy density of 89.6 Wh kg(-1), an amazing power density of 20.07 kW kg(-1), and superior cycling performance (86.8% capacitance retention after 50 000 cycles). Such exceptional electrochemical performance of Co-Mo-S NS is ascribed to the good electrical contact with the 3D Ni foam, ultra-high contact area with the electrolyte, and enhanced architectural softening during the charging/discharging process. It is expected that the fabricated, unique, ultra-thin Co-Mo-S NS have great potential for future energy storage devices.

    Mountains are water towers that provide water security to many billions of people. An outstanding question is how climate change may affect surface-groundwater interactions in snow and ice-covered catchments. To address this question, we applied the Variable Infiltration Capacity (VIC) model to the seasonally snow-covered Como Creek watershed to simulate discharge. The results for the years 2005-2008 show that the simulated discharge approximated the measured data in 2008, while the other years have been underestimated. As for the year 2008, sensitivity analysis shows that the correctly simulated discharge depends greatly on soil depth2, depth3 and Ws. For example, a 1% increase in soil depth2, depth3 or Ws leads to 1.3%, 0.8% and 1.3% increases in the Nash-Sutcliffe efficiency (Er). When depth2 and depth3 increased at the same time, Er increased higher than merely depth2 or depth3. The VIC results suggest that 85% of discharge is from groundwater in this snow-covered catchment. End-member mixing analysis using isotopic and geochemical tracers in 2010 showed that groundwater is the main water source for discharge, suggesting that the VIC modeling results are reasonable. The calibration of the VIC model serves as the basis for future projections in discharge after perturbations such as climate change and increases in the magnitude and timing of wildfires.

    Las neoplasias mieloproliferativas (NMP) son alteraciones crónicas de las células madre hematopoyéticas clonales caracterizadas por una mayor producción de granulocitos, glóbulos rojos o plaquetas. Una de las principales complicaciones de las NMP es la aparición de problemas trombóticos venosos y arteriales causados por un aumento en la agregación plaquetaria y la generación de trombina. Se evaluaron 11 casos de mielofibrosis primaria (MP), de los cuales dos debutaron con trombosis venosa esplácnica (TVE). Tras observar los resultados de este estudio y de la literatura mundial, se sugiere que al evaluar pacientes con TVE se incluyan métodos diagnósticos para MP, como la mutación JAK2V617F. Myeloproliferative neoplasms are chronic disorders of clonal hematopoietic stem cells, characterized by an overproduction of functional granulocytes, red blood cells and / or platelets, and one of the major complications is the occurrence of venous and arterial thrombotic problems caused by increased platelet aggregation and thrombin generation. In this study 11 cases of primary myelofibrosis (PM) were evaluated and 2 debuted with splanchnic venous thrombosis (SVT); so after seeing the results of this study and of world literature, it is suggested that in patients with SVT, diagnostic methods for PM like the JAK2V617F mutation should be included.

    Climate change is impacting water users in many sectors: water supply, farming, industry, hydropower, fishing, housing, navigation and health. Existing situations, like population growth, movement of populations from rural to urban areas, poverty and pollution can aggravate the impacts of climate change. The aim of the study is to evaluate the vulnerability of different water user groups to climate change and define communities' adaptation strategies in the Comoe River Basin. Information was collected on communities' concerns and perception on changes in climate and potential adaptation measures and strategies. Results show that 95 % of the sample in the study communities had heard of it and are aware that climate change is occurring. They have been experiencing changes in economic activity and cropping pattern, reduced water level in rivers, crop failure, delay in cropping season, new pests and diseases, food insecurity, drop in income and decline in crop yield. Results also show that communities employ various adaptation strategies including crops diversification, substitution and calendar redefinition, agroforestry, borrowing from friends and money lenders and increasing fertilizer application.

    A kinetic model has been developed to describe the growth of single-walled carbon nanotubes (SWNT) in the CoMoCAT method, which is based on the disproportionation of CO on supported CoMo catalysts. The model attempts to capture mathematically the different stages involved in this method: (i) catalyst activation or in-situ creation of active sites, i.e., reduced Co clusters by transformation of CoMoOx precursor species, or oxidized sites; (ii) CO decomposition over active sites, which increases the surface fugacity of carbon until reaching a certain threshold; (iii) nucleation of ordered forms of carbon; (iv) C diffusion (both across the surface and into the metal particle); (v) SWNT growth; (vi) termination, by either deactivation of the catalyst active sites or by increase in the carbon concentration at the metal/SWNT interface, approaching that of the metal/gas interface and eliminating the driving force for diffusion. Previous investigations have only explained the growth termination by the former. Here, we emphasize the possible contribution of the later and propose a novel "hindrance factor" to quantify the effect of nanotube interaction with its surroundings on the growth termination. To test the kinetic model and obtain typical values of the physical parameters, experiments have been conducted on a CoMo/SiO2 catalyst in a laboratory flow reactor, in which the rate of carbon deposition was continuously evaluated by the direct measurement of the CO2 evolution as a function of time. The experimental data are fitted very well with model.

Materiales y Metodos Los sujetos diabéticos libres de demencia pertenecientes al Estudio Nacional de Salud y Envejecimiento en México fueron evaluados a los dos años de la línea de base. Se estudió el papel de los factores sociodemográficos, de otras comorbilidades y del tipo de tratamiento en la conversión a demencia. Resultados Durante la línea de base 749 sujetos (13.8%) tuvieron diabetes. El riesgo de desarrollar demencia en estos individuos fue el doble (RR, 2.08 IC 95%, 1.59–2.73). Se encontró un riesgo mayor en individuos de 80 años y más (RR 2.44 IC 95%, 1.46–4.08), en los hombres (RR, 2.25 IC 95%, 1.46–3.49) y en sujetos con nivel educativo menor de 7 años. El estar bajo tratamiento con insulina incrementó el riesgo de demencia (RR, 2.83, IC 95%, 1.58–5.06). Las otras comorbilidades que aumentaron el riesgo de demencia en los pacientes diabéticos fueron la hipertensión (RR, 2.75, IC 95%, 1.86–4.06) y la depresión (RR, 3.78, 95% IC 2.37–6.04). Conclusión Los sujetos con diabetes mellitus tienen un riesgo mayor de desarrollar demencia, La baja escolaridad y otras comorbilidades altamente prevalentes en la población Mexicana contribuyen a la asociación diabetes-demencia.

    We analyse, from first-principles, the energetics and magnetic ordering of sigma phases in Co-Mo and Fe-Mo systems. Total energy differences between the sigma phase and Standard Element Reference (SER) structures are calculated in the whole concentration range at equilibrium volumes by means of the linear muffin-tin orbitals method in the atomic-sphere approximation (LMTO-ASA), the full-potential linearised augmented-plane waves (FLAPW) method and the pseudopotential approach. They are compared with the enthalpy of formation of sigma phase obtained from the phase equilibria calculations at higher temperature based on the semiempirical CALPHAD (CALculation of PHAse Diagram) method. It turns out that the binary sigma phases are more stable than the weighted average of the sigma phase of elemental constituents and that this stability for Fe-Mo is higher than for Co-Mo. On the other hand it was found that the binary sigma phases do not exhibit any stability with respect to the weighted average of the SER structures. The magnetic configurations in all systems are investigated and the stabilizing effect of magnetic order in sigma phase at 0 K is presented. It turns out that the atomic magnetic moment strongly depends on the type of occupied sublattice and total composition of the alloy.

    En investigaciones previas sobre el acogimiento familiar y la adopción en Ayacucho, se ha podido descubrir cómo los ayacuchanos adquieren y producen relaciones sociales. Mientras negocian creativamente los discursos y espacios construidos simultáneamente por instituciones, comunidades, y estructuras sociales, van adquiriendo nuevas formas de relacionarse. Este artículo discute el proceso opuesto: el deshacerse de relaciones de parentesco, y el proceso social del abandono o alejamiento. Cuando se aleja a una persona de su familia o su comunidad, los que se quedan en ella llegan a entenderse como ciertos tipos de personas. En los estudios de caso discutidos aquí, recopilados a través de una detallada y cuidadosa observación participante y de entrevistas etnográficas grabadas entre 2001 y 2007, se puede ver cómo, después de un alejamiento social, los individuos que alejan se reinterpretan como sujetos que se encuentran superándose o volviéndose modernos, o bien sacrificándose.

    Lake Como (northern Italy) is the deepest Italian lake, reaching a depth of about 425 m. The lambda-shaped lake expands about 45 km in NE-SW direction. Southwards of the hydrologically closed western branch, two sediment cores of 70 m (S1) and 65 m length (S2) were taken in the year 2005 close to the cathedral of Como (Piazza Verdi). The drilling sites are located in the middle of the Southern Alps, some 300 m from the present-day lakeshore. The cores provide the first detailed Late Glacial to Holocene multi-proxy record for the Lake Como basin. Our research is aimed at investigating the environmental and geological evolution of the Insubria Region. The multi-proxy study of the stratigraphic sequences contain geophysical, geotechnical, sedimentological, paleobotanical, and radiocarbon analyses. They have been performed for core S1 and are still in progress on core S2. With this data the working group focuses on two main issues. The first topic is the reconstruction of the natural and anthropogenic processes controlling the ground subsidence in the Como urban area (e.g., Comerci et al., 2007) and another aim is to reconstruct vegetation and land-use dynamics. In particular, 150 samples of vegetal macroremains have been collected in the palustrine deposits along S1 core, down to 31,00 m. Below this depth (dated 14C 12,496 ± 55 yr BP - 15,050 - 14,250 cal yr BP), the amount of plant macroremains in the sediment drops dramatically. The taxonomic determination was carried out on more than 800 macroremains. They are represented by fragments of wood, leaves, needles, seeds, fruits, mosses and tiny charcoals (Motella, 2009, unpublished PhD Thesis). Picea/Larix, Pinus sp., Juniperus with Betula, found in the deeper levels (30.80 - 30.00 m), are the first arboreal taxa that colonized the shores of Lake Como, and show that the reforestation began in this area about 16,000 years ago. During the early Holocene (25.10 m) Abies alba expanded and further upwards the sequence

    CoMoS phase with metallic character plays crucial role on enhancing the activity of MoS2 electrocatalysts for hydrogen evolution reaction (HER). However, only Co atoms located in the edges of MoS2 can create CoMoS phase, so it is a challenge to obtain CoMoS phase with homogeneous distribution limited by the layered MoS2 and doping method of Co. Herein, we reported a simple one-pot hydrothermal method to prepare novel ternary CoS2/MoS2/RGO with CoMoS phase for HER using reduced graphene oxide (RGO) as support. XPS proves the formation of CoMoS phase, implying the enhanced activity for HER. RGO support ensures the well distribution of CoMoS phase and enhances the conductivity of CoS2/MoS2/RGO. Compared to CoS2/RGO, MoS2/RGO and CoS2/MoS2, the obtained CoS2/MoS2/RGO shows superior activity for HER with an onset overpotential of -80 mV (vs. RHE), small Tafel slope of 56 mV dec-1, high exchange current density of 11.4 μA cm-2 and rigid electrochemical durability. The enhanced performances for HER may be ascribed to the formation of CoMoS phase with high activity and the existence of RGO support with good electrical conductivitys in ternary CoS2/MoS2/RGO. Therefore, the introduction of CoMoS phase and RGO into MoS2 could effectively enhance electrocatalytic properties for HER.

    We investigated the reactions between cobalt-oxides and water molecules using photoelectron spectroscopy and density functional calculations. It has been confirmed by both experimental observation and theoretical calculations that dihydroxide anions, Co(m)(OH)(2)(-) (m = 1-3), were formed when Co(m)O(-) clusters interact with the first water molecule. Addition of more water molecules produced solvated dihydroxide anions, Co(m)(OH)(2)(H(2)O)(n)(-) (m = 1-3). Hydrated dihydroxide anions, Co(m)(OH)(2)(H(2)O)(n)(-), are more stable than their corresponding hydrated metal-oxide anions, Co(m)O(H(2)O)(n+1)(-). © 2011 American Institute of Physics

    Este trabalho visa analisar a possibilidade de relacionar conteúdos aplicados no ensino fundamental e médio de forma interdisciplinar por intermédio da astronomia, com a intervenção de objetos de aprendizagem que possam integrar as disciplinas e a utilização de recursos tecnológicos. Em uma pesquisa prévia com 20 professores de uma escola estadual situada na cidade de Guarulhos foi observado que apenas 25% dos professores utilizam algum recurso tecnológico para o desenvolvimento de conteúdos pertinentes à sua disciplina, tais como sites e softwares educativos, sendo que a maioria absoluta continua ensinando apenas com livros didáticos. A maior parte dos professores apresenta dificuldades em trabalhar sua disciplina de forma interdisciplinar, ou seja, 75% dos professores preferem aplicar os conteúdos seguindo uma hierarquia linear de tópicos, evitando a discussão de temas que de alguma forma estão relacionados. A astronomia pode vir à fascinar o ser humano e despertar sua curiosidade promovendo um maior interesse no aprendizado, podendo favorecer análises interdisciplinares de forma lógica e objetiva, desta forma colocar a astronomia como tema motivador interdisciplinar, pode ser relevante no que se refere ao distanciamento da fragmentação dos conteúdos. No Estado de São Paulo, a implantação da proposta curricular no ensino fundamental e médio mostra claramente a inserção da astronomia na maior parte das séries, principalmente na 6ª série em que todo o bimestre se fala de astronomia.

    Las fulguraciones solares son fenómenos transitorios de liberación de energía que se desarrollan en las estructuras magnéticas de las regiones activas del Sol. Las fulguraciones pueden llegar a liberar hasta 1032 erg en 100 seg. en todo el rango electromagnético, y acelerar partículas. En este trabajo mostramos que la ubicación de los abrillantamientos en Hα de diversas fulguraciones está relacionado con las propiedades de las conexiones de las líneas del campo magnético de la región, como se espera por las teorías de reconexión en 3D recientemente desarrolladas (Démoulin et al, 1996a). El campo magnético coronal se extrapola del campo fotosférico observado suponiendo una configuración libre de fuerzas lineal. Por medio de un algoritmo se determinan las regiones donde existe un cambio drástico en la conectividad de las líneas de campo (límites ``cuasi-discontinuos'', o cuasi-separatrices CS). Las CS son bandas abiertas que identifican zonas donde el campo magnético se reconectará con más probabilidad y, siempre que las mismas sean lo suficientemente finas, se producirá allíla liberación de energía proveniente del campo magnético. Hemos encontrado que en todas las regiones fulgurantes estudiadas (Démoulin et al, 1996b) existen CS en los mismos lugares donde se observaron los abrillantamientos en Hα. Allídonde coinciden los abrillantamientos con las CS, éstas tienen un espesor menor que 1 Mm. Las líneas de campo coronales extrapoladas de nuestro modelo tienen sus orígenes fotosféricos a ambos lados de las CS, como se espera dados los recientes estudios de reconexión magnética en 3D. Estos resultados ponen a prueba los modelos presentes sobre fulguraciones solares.

    Hydrotreatment catalytic operations are commonly performed industrially by layered molybdenum sulfide promoted by cobalt or nickel in order to remove heteroelements (S, N, O) from fossil fuels and biofuels. Indeed, these heteroelements are responsible of the emission of pollutants when these fuels are used in vehicles. In this respect, previous studies made by our research group have shown that the active phase under steady state conditions is partially carbided while strong bending effects of MoS2 slabs were also observed. However, up to now, the morphology of the resulting Co/MoSxCy carbided catalyst has not been fully characterized. In the present study, for the first time, a chemical reaction between the carbon content of a TEM Cu/C grid and a freshly sulfide Co/MoS2 catalyst was in situ observed at 300 °C and 450 °C by HRTEM experimental techniques at ~10 nm of resolution. Results indicate that bending of MoS2 layers occurred due to carbon addition on MoS2 edge sites, as observed in stabilized catalysts after HDS reaction. Using a silicon grid, only cracks of MoS2 slabs were observed without bending effect confirming the role of structural-carbon in this change of morphology.

    Although banned in many countries for decades, DDTs and PCBs still represent a global threat to food safety. As these contaminants are still present in aquatic ecosystems, fish can be an important contributor to their total dietary intake. Alosa agone specimens were sampled over a period of 10 years (from 2006 to 2015) to provide a representative overview of the DDT and PCB levels of Lago di Como, a deep Italian lake where a DDT input due to secondary sources was observed in recent years. The potential health risk from the consumption of both fresh and preserved fish was evaluated. While DDT levels have generally decreased during the monitored period, reaching quite stable levels, PCB concentrations were variable, with values exceeding, in some cases, the European Union limit for human consumption and enabling potential carcinogenic effects. However, typical local processing of this fish species markedly appeared to decrease these contaminant levels, thus making the fish product (called missoltino) a safer food. The results of this work highlighted the need of continuous biomonitoring of those contaminants considered a past issue along with the emergent ones. Copyright © 2017 Elsevier Inc.

  11. [The indigenous population of Sierra Norte de Puebla].

    1991-06-01

    The northern sierra region of Pueblo, Mexico, contains 1496 communities in 65 municipios and covers 1/4 of the area of the state of Puebla. The topography is steep and mountainous, and the area is inaccessible. The region contains the 3 principal zones of Mesoamerica, hot lands from sea level to 700 meters above sea level, temperate zones from 700-1500 meters, and cold country from 1500-2000 meters above sea level. Most of the population resides in the temperate and cold lands, but the hot zones are economically important. Little is known of the prehistory of the area. The Totonac were believed to have been the earliest settlers. In the mid-15th century numerous Nahua groups came to the area. In the late 15th century the region fell to the Aztecs, but their dominion was cut short by the arrival of the Spanish. Spanish penetration was relatively slow because of the difficult terrain and the lack of precious metals desired by the Spanish. The introduction of coffee cultivation in the late 19th century accelerated the adoption of urban-mestizo sociocultural and commercial elements by the indigenous population. The population of the northern sierra increased from 752,656 in 1980 to 965,976 in 1990. The 1980 census reported that 259,140 persons spoke indigenous languages, including 179,677 who spoke Nahuatl, 66,020 Totonaco, and 4921 Otomi. The most important cities are located on paved roads: Teziutland, Zacatlan, Hauachinango, and Zacapoaxtla. The municipios with predominantly monolingual indigenous populations are concentrated in the most difficult to reach areas of the central sierra massif. The region is characterized by temporary and permanent emigration of the indigenous population. The main reasons for emigration are lack of land and of alternative sources of employment, and desire for education. During the months August-December, known as the time of hunger, there is seasonal migration of household heads in search of work as laborers in cane cutting, tobacco, or fruit harvesting. The local economy is based on subsistence agriculture and production of coffee, fruits, and woods for export. The most isolated and inaccessible communities have preserved traditional cultural elements the most strongly.

    The rampant success of quantum theory is the result of applications of the 'new' quantum mechanics of Schrodinger and Heisenberg (1926-7), the Feynman-Schwinger-Tomonaga Quantum Electro-dynamics (1946-51), the electro-weak theory of Salaam, Weinberg, and Glashow (1967-9), and Quantum Chromodynamics (1973-); in fact, this success of 'the' quantum theory has depended on a continuous stream of brilliant and quite disparate mathematical formulations. In this carefully concealed ferment there lie plenty of unresolved difficulties, simply because in churning out fabulously accurate calculational tools there has been no sensible explanation of all that is going on. It is even argued that such an understanding is nothing to do with physics. A long-standing and famous illustration of this is the paradoxical thought-experiment of Einstein, Podolsky and Rosen (1935). Fundamental to all quantum theories, and also their paradoxes, is the location of sub-microscopic objects; or, rather, that the specification of such a location is fraught with mathematical inconsistency. This project encompasses a detailed, critical survey of the tangled history of Position within quantum theories. The first step is to show that, contrary to appearances, canonical quantum mechanics has only a vague notion of locality. After analysing a number of previous attempts at a 'relativistic quantum mechanics', two lines of thought are considered in detail. The first is the work of Wan and students, which is shown to be no real improvement on the iisu.al 'nonrelativistic' theory. The second is based on an idea of Dirac's - using backwards-in-time light-cones as the hypersurface in space-time. There remain considerable difficulties in the way of producing a consistent scheme here. To keep things nicely stirred up, the author then proposes his own approach - an adaptation of Feynman's QED propagators. This new approach is distinguished from Feynman's since the propagator or Green's function is not obtained by Feynman's rule. The type of equation solved is also different: instead of an initial-value problem, a solution that obeys a time-symmetric causality criterion is found for an inhomogeneous partial differential equation with homogeneous boundary conditions. To make the consideration of locality more precise, some results of Fourier transform theory are presented in a form that is directly applicable. Somewhat away from the main thrust of the thesis, there is also an attempt to explain, the manner in which quantum effects disappear as the number of particles increases in such things as experimental realisations of the EPR and de Broglie thought experiments.

    Environmentally friendly electrochemical hydrogen production needs the development of earth-abundant catalyst materials for the hydrogen evolution reaction with high activity and durability at neutral pH. In this work, the self-templating construction of a hollow amorphous CoMoS4 nanotube array on carbon cloth (CoMoS4 NTA/CC) is reported, using hydrothermal treatment of a Co(OH)F nanowire array on CC in (NH4 )2 MoS4 solution. When used as a 3D electrode for hydrogen evolution electrocatalysis, the resulting CoMoS4 NTA/CC demonstrates superior catalytic activity and strong long-term electrochemical durability in 1.0 M phosphate buffer solution (pH=7). It shows small onset overpotential of 21 mV and requires low overpotentials of 104 and 179 mV to drive geometrical current densities of 10 and 50 mA cm(-2) , respectively. Density functional theory calculations suggest that CoMoS4 has a more favorable hydrogen adsorption free energy than Co(OH)F. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Effective electrocatalysts for the hydrogen evolution reaction (HER) in alkaline electrolytes can be developed via a simple solvothermal process. In this work, first, the prepared CoMoS nanomaterials through solvothermal treatment have a porous, defect-rich, and vertically aligned nanostructure, which is beneficial for the HER in an alkaline medium. Second, electron transfer from cobalt to MoS2 that reduces the unoccupied d orbitals of molybdenum can also enhance the HER kinetics in an alkaline medium. This has been demonstrated via a comparison of the catalytic performances of CoMoS, CoS, and MoS2. Third, the solvothermal treatment time evidently impacts the electrocatalytic activity. As a result, after 24 h of solvothermal treatment, the prepared CoMoS nanomaterials exhibit the lowest onset potential (42 mV) and overpotential (98 mV) for delivering a current density of 10 mA cm(-2) in a 1 M KOH solution. Thus, this study provides a simple method to prepare efficient electrocatalysts for the HER in an alkaline medium.

    Atualmente vivencia-se um mundo globalizado onde os computadores e a internet permitiram um acesso rápido e seguro a todo tipo de informação e conhecimento. O presente trabalho visa analisar a maneira pela qual alunos de segundo grau da rede estadual da cidade de São Paulo obtiveram, caso tenham, conhecimentos básicos de astronomia quanto aos fenômenos celestes que os rodeiam, tais como a sucessão dos dias e das estações do ano, além de questioná~los sobre fatos genéricos tais como: o que vem a ser o Sol, o Big Bang, o que ocasionou a extinção dos dinossauros. Para tanto foi elaborado um formulário constando de questões de múltipla escolha, o qual foi aplicado no primeiro colegial diurno da Escola Estadual Guilherme de Almeida. Num espaço amostral de 44 alunos constatou-se que 41% dos alunos adquiriram seus conhecimentos astronômicos na escola e 59% através da mídia em geral. Neste mesmo espaço amostral apenas 11% dos alunos usaram computadores na escola, 41% na residência, 5% no trabalho e 43% não utilizaram. O presente estudo revelou também que para 50% dos alunos o professor jamais utilizou um programa de computador a respeito de astronomia ou fez alguma apresentação sobre o tema. Embora em sua fase inicial este estudo revela claramente que a maioria dos alunos não obtém na escola seus conhecimentos astronômicos, estes provém de fontes não especificamente didático-pedagógicas tais como filmes e revistas populares que não raramente geram conhecimentos incompletos e em muitos casos inclusive falhos.

    Para a maioria dos estudantes, sua passagem pelo ensino formal fundamental envolve a transmissão de fatos que devem ser guardados para um exame, a habilidade para lembrar fórmulas e, eventualmente, a repetição de experimentos que devem produzir resultados exigidos pelo professor. O resultado deste modelo de ensino, ao longo dos anos, é conhecido por todos: desconhecimento e descontentamento, por parte dos estudantes, de temas relativos ao papel e aos processos da ciência. Acreditamos que a Astronomia, pelo seu caráter observacional, é uma das áreas do conhecimento que pode contribuir neste cenário. A Fundação Planetário da Cidade do Rio de Janeiro possui um telescópio Meade LX-200 (25cm) que, juntamente com as câmeras CCD ST-7E e ST8E, tem sido utilizado em projetos voltados aos estudantes do ensino médio desde o ano 2000. Tais projetos envolvem a condução de um projeto de pesquisa observacional num nível apropriado, e possibilitam o contato com técnicas e novas tecnologias: computador, software para manipulação de dados e gráficos, programas de tratamento e redução de dados, uso de equipamentos óptico-eletrônicos (telescópio e CCD), bem como o processo de aquisição de conhecimento. Dentro da proposta dos anos anteriores, priorizamos projetos de uma noite, ou seja, procuramos trabalhar com fenômenos que apresentem variabilidade com intervalo de recorrência relativamente curto. Em todos os casos, optamos pela fotometria diferencial, que tem se mostrado bastante eficiente para o céu luminoso como o da cidade do Rio de Janeiro.

    Combined pollen, charcoal and modeling evidence from the Insubria Region suggests that fire was a major driver of late Holocene vegetation change. However, the extent and timing of fire response dynamics are not clear yet. We use lacustrine sediments from Lago di Como (N-Italy, S-Alps) to assess if the reconstructed vegetation and fire dynamics were relevant at large scales and if they coincided in time with those observed at smaller sites. The lake, due to its size (142 km2) and economic potential, was very attractive for early land use and human presence in this area is well documented since ca. 10,000 yrs ago (Mesolithic). We used pollen, plant macrofossils and charcoal to reconstruct the vegetation composition and fire activity. During the Younger Dryas and the Early Holocene until ca. 8000 cal BP natural dynamics prevailed. Subsequently, land use and slash-and-burn activities increased at the Mesolithic-Neolithic transition and became widespread around ca. 6500 cal BP. Microscopic charcoal and numerical analyses demonstrate that anthropogenic fires had a determinant influence on long-term vegetation dynamics at regional scales in Insubria. Microscopic charcoal and pollen and spores indicative of land use show that human pressure intensified after ca. 5300 cal yr BP and even more since ca. 4300 cal yr BP. Our results suggest that important species which disappeared or were strongly reduced by land use and fire (e.g. Abies alba, Tilia, Ulmus) will potentially reestablish in the Lago di Como area and elsewhere in Insubria, if land abandonment initiated in the 1950s will continue.

    One of the greatest environmental and social-economics threats is climate change. This topic, in the next few years, will have a significant impact on the availability of water resources of many regions. This is compounded by the strong anthropization of water systems that shows an intensification of conflicts for water resource exploitation. Therefore, it is necessary a sustainable manage of natural resources thorough knowledge of the hosting territories. The development of investigation and data processing methods are essential to reduce costs for the suitable use and protection of resources. Identify a sample area for testing the best approach is crucial. This research aims to find a valid methodology for the characterization, modeling and management of subalpine urban aquifers, and the urban district of Como appears perfect. The city of Como is located at the southern end of the western sector of Lake Como (N Italy). It is a coastal town, placed on a small alluvial plain, therefore in close communication with the lake. The plain is drained by two streams, which are presently artificially buried, and have an underground flow path in the urban section till the mouth. This city area, so, is suitable for this project as it is intensely urbanized, its dimensions is not too extensive and it is characterized by two aquifers very important and little known. These are a shallow aquifer and a deep aquifer, which are important not only for any water supply, but also for the stability of the ground subsidence in the city. This research is also the opportunity to work in a particular well-known area with high scientific significance; however, there is complete absence of information regarding the deep aquifer. Great importance has also the chosen and used of the more powerful open source software for this type of area, such as PHREEQC, EnvironInsite, PHREEQE etc., used for geological and geochemical data processing.

    This study focuses on the potential role of technical and institutional innovations for improving water management in a multi-user context in Burkina Faso. We focus on a system centered on three reservoirs that capture the waters of the Upper Comoé River Basin and servicing a diversity of users, including a sugar manufacturing company, a urban water supply utility, a farmer cooperative, and other downstream users. Due to variable and declining rainfall and expanding users’ needs, drastic fluctuations in water supply and demand occur during each dry season. A decision support tool was developed through participatory research to enable users to assess the impact of alternative release and diversion schedules on deficits faced by each user. The tool is meant to be applied in the context of consultative planning by a local user committee that has been created by a new national integrated water management policy. We contend that both solid science and good governance are instrumental in realizing efficient and equitable water management and adaptation to climate variability and change. But, while modeling tools and negotiation platforms may assist users in managing climate risk, they also introduce additional uncertainties into the deliberative process. It is therefore imperative to understand how these technological and institutional innovations frame water use issues and decisions to ensure that such framing is consistent with the goals of integrated water resource management.

    In order to identify pathogenic trypanosomes responsible for African trypanosomiasis, and to better understand tsetse-trypanosome relationships, surveys were undertaken in three sites located in different eco-climatic areas in Côte d’Ivoire during the dry and rainy seasons. Tsetse flies were caught during five consecutive days using biconical traps, dissected and microscopically examined looking for trypanosome infection. Samples from infected flies were tested by PCR using specific primers for Trypanosoma brucei s.l., T. congolense savannah type, T. congolense forest type and T. vivax. Of 1941 tsetse flies caught including four species, i.e. Glossina palpalis palpalis, G. p. gambiensis, G. tachinoides and G. medicorum, 513 (26%) were dissected and 60 (12%) were found positive by microscopy. Up to 41% of the infections were due to T. congolense savannah type, 30% to T. vivax, 20% to T. congolense forest type and 9% due to T. brucei s.l. All four trypanosome species and subgroups were identified from G. tachinoides and G. p. palpalis, while only two were isolated from G. p. gambiensis (T. brucei s.l., T. congolense savannah type) and G. medicorum (T. congolense forest, savannah types). Mixed infections were found in 25% of cases and all involved T. congolense savannah type with another trypanosome species. The simultaneous occurrence of T. brucei s.l., and tsetse from the palpalis group may suggest that human trypanosomiasis can still be a constraint in these localities, while high rates of T. congolense and T. vivax in the area suggest a potential risk of animal trypanosomiasis in livestock along the Comoé River.

    In the isostructural oxides Ca(3)CoMO(6) (M = Co, Rh, Ir), the CoMO(6) chains made up of face-sharing CoO(6) trigonal prisms and MO(6) octahedra are separated by Ca atoms. We analyzed the magnetic and electronic properties of these oxides on the basis of density functional theory calculations including on-site repulsion and spin-orbit coupling, and examined the essential one-electron pictures hidden behind results of these calculations. Our analysis reveals an intimate interplay between Jahn-Teller instability, uniaxial magnetism, spin arrangement, metal-metal interaction, and spin-orbit coupling in governing the magnetic and electronic properties of these oxides. These oxides undergo a Jahn-Teller distortion, but their distortions are weak, so that their trigonal-prism Co(n+) (n = 2, 3) ions still give rise to strong easy-axis anisotropy along the chain direction. As for the d-state split pattern of these ions, the electronic and magnetic properties of Ca(3)CoMO(6) (M = Co, Rh, Ir) are consistent with d(0) < (d(2), d(-2)) < (d(1), d(-1)) but not with (d(2), d(-2)) < d(0) < (d(1), d(-1)). The trigonal-prism Co(3+) ion in Ca(3)Co(2)O(6) has the L = 2 configuration (d(0))(1)(d(2), d(-2))(3)(d(1), d(-1))(2) because of the metal-metal interaction between adjacent Co(3+) ions in each Co(2)O(6) chain, which is mediated by their z(2) orbitals, and the spin-orbit coupling of the trigonal-prism Co(3+) ion. The spins in each CoMO(6) chain of Ca(3)CoMO(6) prefer the ferromagnetic arrangement for M = Co and Rh but the antiferromagnetic arrangement for M = Ir. The octahedral M(4+) ion of Ca(3)CoMO(6) has the (1a)(1)(1e)(4) configuration for M = Rh but the (1a)(2)(1e)(3) configuration for M = Ir, which arises from the difference in the spin-orbit coupling of the M(4+) ions and the Co···M metal-metal interactions.

    Evaluar el estrés, los riesgos psicosociales asociados al puesto de trabajo y el burnout en un grupo de residentes en el servicio de urgencias; y analizar qué variables se relacionan y predicen mejor el burnout. Estudio analítico y transversal en el que han participado 42 médicos internos residentes que hacen guardias en el servicio de urgencias del Hospital Universitario San Cecilio, Granada. Se han utilizado la versión adaptada al español de la Perceived Stress Scale para evaluar el estrés, el Maslach Burnout Inventory (MBI) para valorar el desgaste profesional, y el cuestionario adaptado y baremado para la autoevaluación de riesgos psicosociales en el trabajo (CopSoQ-ISTAS21). El 78% de los residentes evaluados se encuentra en la categoría desfavorable o intermedia en todas las dimensiones del CopSoQ-ISTAS21, y destaca que el 90% presenta una puntuación desfavorable en exigencias psicológicas. Además, en el MBI el 45% presenta conjuntamente un alto agotamiento emocional y una elevada despersonalización. La dimensión de exigencias psicológicas del ISTAS21 (b = 0.393; p < 0.003) y las puntuaciones de estrés (b = 0.451; p < 0.001) predicen significativamente el agotamiento emocional (r(2) = 0.443). Por último, el 38% ha sufrido una amenaza/agresión en el servicio de urgencias. La situación de los residentes parece perjudicial para su desempeño profesional debido a los altos riesgos psicosociales asociados al puesto de trabajo. Las exigencias psicológicas se proponen como un importante predictor del burnout. Se recomiendan intervenciones psicológicas y estructurales con las que mejorar la situación de los residentes que realizan guardias en el servicio de urgencias.

    El proceso de estigmatización asume una devaluación de la persona debido a una característica o marca que haya sido identificada socialmente y que permita que se le describa como diferente. Desde que se desató la epidemia del VIH/SIDA, vivir con la enfermedad ha sido señalado de manera social como una marca estigmatizante. Las manifestaciones de dicha estigmatización se han documentado entre profesionales de la salud. Este estigma puede afectar los servicios de salud que las personas que viven con VIH/SIDA reciben de estos profesionales. Los objetivos de esta investigación fueron explorar: 1) la percepción que tienen estudiantes y profesionales de la salud sobre su nivel de competencia para ofrecer servicios a personas que viven con VIH/SIDA, 2) las opiniones de éstos sobre el tipo de adiestramiento profesional recibido y la necesidad del mismo, y 3) la manifestación de actitudes estigmatizantes como indicadores de necesidad de adiestramiento profesional. La muestra total del estudio estuvo compuesta por 80 de diversas profesiones de la salud. Los resultados reflejan que algunos/as de los/as participantes han recibido formación en VIH pero ésta no ha sido suficiente para contrarrestar las nociones estigmatizantes. Discutimos las implicaciones de los resultados para investigaciones futuras y el desarrollo de intervenciones con vías de minimizar las nociones estigmatizantes en los escenarios de salud.

    The areas covered by this report lies in the eastern Cordillera of the Colombian Andes in the region around Bucaramanga. This part of the eastern Cordillera consists of a structurally complex core of metamorphic and igneous rocks of Precambrian to Mesozoic age, flanked to east and west by faulted and folded sedimentary strata of late Paleozoic to Tertiary age. Infaulted blocks of sedimentary rocks are locally present in the massif. Unconsolidated deposits of Quaternary age, primarily terraced alluvium, are 10cally extensive in valleys on the flanks of the range. The crystalline central core of the range is called the Santander massif. In it are located the principal sold deposits and scattered deposits of copper, lead, zinc, and fluorite. The sedimentary rocks flanking the massif contain significant deposits of phosphate rock and gypsum, as well as other nonmetallic industrial minerals such as limestone, barite, glass sand, and coal. A belt of lead-zinc prospects in carbonate and sandstone beds of Cretaceous age on the east side of the range warrants further investigation. Gold and silver are the only important metallic minerals that have been produced in the Santander massif. Mining dates back to colonial and possibly to pre-colonial times and continues on a small scale at present. The California and Vetas district was the main area of investigation of metallic minerals during the present project. Results of geochemical sampling of stream sediments and assays of vein material indicate that the main potential of the area is in gold with lesser potentials in copper, lead, zinc, and silver. Mineralization of the district is probably younger than Early Cretaceous. Although no copper minerals have been mined elsewhere in the massif, small amounts of copper minerals in various rocks in scattered areas is revealed by green and blue stains of copper carbonates and sulfates. Deposits of greatest areal extent are in arkosic conglomeratic beds of the Giron Formation. These are being explored and sampled at the present time (1969). A little lead has been mined and smelted in the past but operations were on a very small scale and of short duration. Small amounts of lead, zinc, and copper minerals accompany dolomite replacement of Cretaceous limestone in a few scattered places, and several promising prospects are being investigated by means of trenches and drilling. One magnetite and several hematite prospects were examined but none offers any potential for economic development. Thick beds of gypsum in Lower Cretaceous limestone on Mesa de Los Santos, south of Bucaramanga are being quarried from outcrops for use in cement manufacture. The deposit was discovered shortly before the present project began, and although its extent beneath overlying strata is not yet determined by drilling, it appears to be in a small evaporite basin of about three kilometers in radius. Reserves of gypsum are large, but future development will have to be by underground mining. Outcrops of Cretaceous limestone of high purity are widespread and are more than adequate to meet all demands, which at present are for cement and calcined lime, road construction material, and to a small extent for agricultural lime and polished decorative stone. Upper Paleozoic limestone of the Diamante Formation crops out in a few places; it has been used near Bucaramanga for cement manufacture. Marble is present in several localities of the Santander massif in Lower Paleozoic and Devonian rocks. Impurities, fractures, and solution cavities render most of it unsuitable for decorative purposes, but selected parts are used in floor tile and terrazo. Recrystallized limestone of the Diamante Formation in the same area, usually referred to as marble, is of uniform high purity throughout a thick and uninterrupted section, and offers a good source of limestone raw material. A little is now used for agricultural lime. The potential of this resource has not been fully evalua

    1988-01-01

    Hydrocarbon abundances and stable-isotopic compositions were measured in wells M5, M26, M35 and M102, which represent a range of depths (1270-2000 m) and temperatures (275-330 degrees C) in the field. In order to simulate the production of the geothermal hydrocarbons, gases were collected from the pyrolysis of lignite in the laboratory. This lignite was obtained from a well which sampled rock strata which are identical to those occurring in the field, but which have experienced much lower subsurface temperatures. In both the well and the laboratory observations, high-temperature environments favored higher relative concentrations of methane, ethane and benzene and generally higher delta 13C-values in the individual hydrocarbons. The best correlation between the laboratory and well data is obtained when laboratory-produced gases from experiments conducted at lower (400 degrees C) and higher (600 degrees C) temperatures are mixed. This improved correlation suggests that the wells are sampling hydrocarbons produced from a spectrum of depths and temperatures in the sediments.

    This paper seeks to contribute to the debate on the decision-making process for the location of large public facilities, responding to the growing demand for greater rationality in public investment whilst still offering services of quality and addressing the problem of spatial friction. The specific problem analysed in this paper is the need to define the best location for a public hospital in a particular region of Portugal. The singularity of the approach adopted lies above all in the segmentation into macro-location and micro-location.

    The geography Mexican migration to the U.S. has experienced deep transformations in both its origin composition and the destinations chosen by migrants. To date, however, we know little about how shifting migrant origins and destinations may be linked to one another geographically and, ultimately, structurally as relatively similar brands of economic restructuring have been posited to drive the shifts in origins and destinations. In this paper, we describe how old and new migrant networks have combined to fuel the well-documented geographic expansion of Mexican migration. We use data from the 2006 Mexican National Survey of Population Dynamics, a nationally representative survey that for the first time collected information on U.S. state of destination for all household members who had been to the United States during the five years prior to the survey. We find that the growth in immigration to southern and eastern states is disproportionately fueled by undocumented migration from non-traditional origin regions located in Central and Southeastern Mexico and from rural areas in particular. We argue that economic restructuring in the U.S. and Mexico had profound consequences not only for the magnitude but also for the geography of Mexican migration, opening up new region-to-region flows.

    A previous study by the U.S. Geological Survey of impaired water bodies in Fort Worth, Texas, reported elevated but variable concentrations of particle-associated contaminants (PACs) comprising chlorinated hydrocarbons, polycyclic aromatic hydrocarbons, and trace elements in suspended and bed sediment of lakes and streams affected by urban land use. The U.S. Geological Survey, in cooperation with the City of Fort Worth, collected additional samples during October 2004 to investigate sources of PACs in the watersheds of two impaired lakes: Lake Como and Fosdic Lake. Source materials and aquatic sediment were sampled and analyzed for PACs. Source materials sampled consisted of street dust and soil from areas with residential and commercial land use and parking lot dust from sealed and unsealed parking lots. Aquatic sediment sampled consisted of bottom-sediment cores from the two lakes and suspended and streambed sediment from the influent stream of each lake. Samples were analyzed for chlorinated hydrocarbons (organochlorine pesticides and polychlorinated biphenyls), polycyclic aromatic hydrocarbons, major and trace elements, organic carbon, grain size, and radionuclides.

  11. The use of remote sensing technologies and models to study pollutants in the Paso del Norte region

    NASA Astrophysics Data System (ADS)

    Mahmud, Suhail

    Using a suite of modeling techniques and instrumentation we study the atmospheric pollutants in the PdN Region. The first objective of this work was to measure hemi-spherically integrated, spectrally resolved solar photon flux (actinic flux) between the wavelengths 300 and 700 nm, and use the measured actinic flux to improve air quality simulations. Actinic flux was measured in the PdN region in order to calculate photolysis rate coefficients for different pollutants. The improved photolysis rate coefficients were then integrated into a photochemical air quality model (CAMx) in order to improve air quality forecasting. We present the simulations performed for a selected 2015 summer ozone episode in the PdN region. Whilst this methodology was applied in the PdN region, it can also be used in any US region. In addition, to compliment this work, we studied the spectral irradiances of this region and compared them with an atmospheric radiation model at different wavelengths. Finally, we have constructed a satellite antenna and developed the software that allows us to retrieve environmental data in real time and to respond pro-actively to the presence of dust storms or other threatening atmospheric phenomena in the PdN region.

    Human myiasis is the parasitism of human tissues by fly larvae. Diagnoses are based on clinical pattern of tissue damage and presence of insect stages. Herein, a case myiasis is described in a seven-year-old female child. She presented with fever associated with abscessed scalp lesions containing exposed larvae. Severe pediculosis was also observed. The patient was hospitalized and treated with clindamycin, gentamicin (for bacterial secondary infections) and ivermectin (treatment for lice) after which the patient showed clinical improvement and was discharged four days later. Since human myiasis can be caused by a number of different species, larvae were collected from the patient and identified as those of Cochliomyia hominivorax (Diptera: Calliphoridae). Because other cases of coinfestation of flies and lice are on record, health workers are to be alerted about the possible pediculosis-myasis risk.

    To analyze and compare the knowledge and opinions of Law and Medical students regarding the issue of abortion in Brazil. This was a cross-sectional study involving 125 graduate students from the class of 2010. Of these, 52 were medical students (MED group) and 73 law students (LAW group). A questionnaire was applied based on published research about the topic. Dependent variables were: monitoring the abortion debate, knowledge concerning situations where abortion is permitted under Brazilian law, opinion about situations that agree with extending legal permission to terminate pregnancy and prior knowledge of someone who has undergone induced abortion. Independent variables were: sex, age, household income and graduation course. χ² and Fisher's exact tests, with the level of significance set at 5%. Most interviewees reported monitoring the debate on abortion in Brazil (67.3% of the MED group and 70.2% of the LAW group, p>0.05). When assessing knowledge on the subject, medical students had a significantly higher percentage of correct answers than law students (100.0 and 87.5%, respectively; p=0.005) regarding the legality of abortion for pregnancies resulting from rape. Elevated percentages of correct responses were also recorded for both groups in relation to pregnancies that threaten the life of the mother (94.2 and 87.5% for MED and LAW groups, respectively), but without statistical significance. A significant percentage of respondents declared they were in favor of extending legal abortion to other situations, primarily in cases of anencephaly (68%), pregnancy severely harming the mother's physical health (42.1%) or that of the fetus in cases of severe congenital malformation (33.7%). Results showed a satisfactory knowledge on the part of law and medical school graduate students regarding the legality of abortion in Brazil, combined with a favorable trend towards extending legal permission to other situations not covered by the law. It is important to underscore the inclusion of this topic in the undergraduate curriculum and the development of inter-professional teaching strategies.

    The lower Colorado is among the most regulated rivers in the world. It ranks as the fifth largest river in volume in the coterminous United States, but its flow is fully allocated and no longer reaches the sea. Lower basin reservoirs flood nearly one third of the river channel and store 2 years of annual flow. Diverted water irrigates 1.5 million ha of cropland and provides water for industry and domestic use by 22 million people in the southwestern United States and northern Mexico. The native fish community of the lower Colorado River was among the most unique in the world, and the main stem was home to nine freshwater species, all of which were endemic to the basin. Today, five are extirpated, seven are federally endangered, and three are being reintroduced through stocking. Decline of the native fauna is attributed to predation by nonnative fishes and physical habitat degradation. Nearly 80 alien species have been introduced, and more than 20 now are common. These nonnative species thrived in modified habitats, where they largely eliminated the native kinds. As a result, the lower Colorado River has the dubious distinction of being among the few major rivers of the world with an entirely introduced fish fauna. ?? 2005 by the American Fisheries Society.

  16. Characterization of risk/exposure to climate extremes for the Brazilian Northeast—case study: Rio Grande do Norte

    Climate change would increase the risk of floods or droughts. So far, only a few studies have projected changes in extremes on a regional or local scale. None of these studies relied on multiple climate proxies. Only some studies have started to estimate the exposure to flooding or drought as a proxy of risk; so, here, we present an exercise in risk analysis. Studies of climate change and its impacts rarely yield consensus on the distribution of exposure, vulnerability or possible outcomes. In addition, Northeast Brazil (NEB) is known for its temporal and spatial variability of rainfall and several studies have investigated this variability in order to understand damaging episodes such as droughts and floods. In NEB, the phenomenon of drought is a complex issue because millions of people are affected, and so, it is an important object of study in various fields of knowledge. One way of trying to argue about this phenomenon is through the concept of vulnerability. In this preliminary study, one will determine the risk or exposure factor to drought, which is one component of vulnerability, mainly concerning agricultural activities. The drought risk/exposure indicator was constructed based on three indices: the standardized precipitation index (SPI), the precipitation concentration period (PCP) and the precipitation concentration degree (PCD). The exposure indices showed an increase in high values from 1979 to 2008. On the contrary, the period from 1967 to 1996 showed that the risk factor in some micro-regions had low indices in a larger number; one can note that the dynamics of the factor is in an evolution between high and extremes.

    A two-year study made in Redwood National Park, Calif., (September 1973-September 1975) determined existing chemical water-quality conditions and identified possible effects of logging on water quality in streams. Water quality was generally good, with dissolved-solids concentrations ranging from 25 to 139 milligrams per liter in the Redwood Creek basin and 21 to 49 milligrams per liter in the Mill Creek basin. Water type and pH tended to shift seasonally. Exposure of soils to the elements in areas logged or having naturally sparse vegetation accelerated chemical weathering and increased dissolved-solids concentrations. Nitrogen and phosphorus concentrations were generally too low to support nuisance algae, but were higher in logged areas. Higher nitrogen concentrations in areas well exposed to sunlight could support modest algae populations. Trace-metal concentrations were low, typical of clean streams. (Woodard-USGS)

    2008-01-01

    We have utilized a range of manufactured or commercial nanoparticulate materials, including surrogate carbon nano-PM along with combustion-generated carbonaceous (soot) nano-PM characteristic of environmental nano-PM (both indoor and outdoor) to investigate and compare their cytotoxic response in vitro with an immortalized human epithelial (lung model) cell line (A549). These have included nano-Ag, Al2O3, TiO2, Fe2O3, ZrO2, Si3N4, chrysotile asbestos, BC, 2 types of MWCNT-aggregate PM (MWCNT-R and MWCNT-N), and high-volume glass fiber collected soots: candle, wood, diesel (truck), tire, and 3-types of natural gas kitchen burner-generated soots: yellow (fuel-rich) flame, low-flow blue flame, and normal flow blue flame soot PM. These carbonaceous nano-PM species can be found in either the indoor and outdoor environments or microenvironments. Two-day and two-week in-vitro cultures of A549 showed cell death (or decreased cell viability) for all nanoparticulate materials, but especially significant for all but the TiO2 and candle, wood, and diesel PM. The natural gas kitchen burner combustion PM cell death response was characteristic of BC and MWCNT PM. There was no correlation with total PAH content of the soot PM. Cytokine release (IL-6, IL-8) was detected for the Ag, Fe2 O3, asbestos, BC and the MWCNT PM. Reactive oxygen species (ROS) production was also detected for Ag, Fe2 O3, ZrO2, asbestos, BC, and the MWCNT aggregate PM, as well as the natural gas kitchen burner combustion PM. TEM, FESEM, and optical microscopy examination of these nanomaterials illustrate the wide range in PM morphologies and crystallinities as well as cell morphologies. Taken together, these results illustrate proinflammatory and related respiratory health issues in relation to environmental nanoparticulates. PMID:18441401

    Laser probe 40Ar/39Ar analyses of individual sanidine grains from four tuffs in the alluvial Late Cretaceous (Campanian) El Gallo Formation yield statistically distinct mean dates ranging from 74.87±0.05 Ma to 73.59±0.09 Ma. The exceptional precision of these dates permits calculation of statistically significant sediment accumulation rates that are much higher than passive sediment loading would cause, implying rapid tectonically induced subsidence. The dates bracket tightly the age of important dinosaur and mammalian faunas previously reported from the El Gallo Formation. The dates support an age less than 73 Ma for the Campanian/Maastrichtian stage boundary, younger than indicated by several currently used time scales. Further application of the single grain 40Ar/39Ar technique may be expected to greatly benefit stratigraphic studies of Mesozoic sedimentary basins and contribute to calibration of biostratigraphic and magnetostratigraphic time scales.

    The San Quintin Volcanic Field (SQVF) is unique for the Baja California peninsula as the only known location of intraplate-type mafic alkalic volcanism and the only known source of peridotitic and granulitic xenoliths. It consists of 10 distinct Quaternary volcanic complexes. The oldest cones mainly erupted primitive magmas (Mg # > 64)(Mg # = 100 × Mg/(Mg + (0.85 × FeTotal))), which carried occasional small xenoliths. As the SQVF evolved with time, differentiated magmas (Mg # < 64) became increasingly common, but primitive magmas, virtually devoid of xenoliths and unusually rich in olivine phenocrysts, dominanted at the youngest cones. Abundances of incompatible elements declined during evolution of the SQVF, implying a temporal increase in the extent of partial melting in the mantle, or progressive exhaustion of these elements in the source. Samples from two cones, Mazo and Ceniza, show relatively low Ce/Pb, ɛNd, and 206Pb/204Pb and high 87Sr/86Sr, which we interpret as evidence for crustal contamination of these magmas. Small isotopic variations for the other cones are collectively interpreted to reflect involvement of at least three mantle components beneath the SQVF. Ranges in isotopic composition overlap for primitive and differentiated rocks, supporting fractional crystallization as the mechanism for deriving the latter from the former. Most differentiated rocks can be successfully modeled by fractional crystallization of olivine, plagioclase, clinopyroxene, and spinel from primitive parents. The largest and most abundant xenoliths were carried by differentiated magmas, indicating that fractional crystallization took place within the mantle, below the level of peridotite entrainment, and reflecting the importance of fractionation-elevated volatile contents for driving these differentiated magmas rapidly to the surface. Primitive rocks of the SQVF are unusual compared to other reported intraplate-type mafic alkalic suites from around the world in having relatively high Al2O3 and Yb, as well as low La/Yb and CaO/Al2O3. These characteristics and trends of rising Al2O3 and falling CaO with decreasing incompatible element abundances are all consistent with origins for the SQVF primitive magmas by progressive partial melting of spinel lherzolite at unusually shallow levels in the mantle.

  4. Is the Caribbean plate subducting underneath Hispaniola? Preliminary results from Caribe Norte wide-angle seismic experiment

    A 200 km long, wide-angle seismic refraction transect was collected in the spring of 2009, across the widest part of the Muertos compressive margin (longitude 69°W). The transect was designed to test the hypothesized subduction of the Caribbean plate’s interior beneath the eastern Greater Antilles island arc. Shots were fired every 90 seconds from the R/V Hesperides’ 3850 cubic inches water-gun array, which, towed at 5 knots, resulted in a shot spacing of ~ 230 m. The seismic signal was recorded by 5 ocean-bottom seismometers deployed at distances varying from 25 to 50 km. Gravity, bathymetry and magnetic data were also acquired along that transect. Published and reprocessed reflection seismic lines nearby provided an initial model of the sediment column and on the pattern of upper crustal reflectors. Preliminary results of a 2-D forward ray-tracing model have enabled us to outline the broad-scale crustal structure across the Muertos margin. The Caribbean oceanic slab shows considerable variations in crustal thickness in the Venezuelan basin area (Caribbean plate’s interior). Farther north, the slab is imaged underneath the Muertos margin to about 60 km north of the deformation front and up to 19 km depth,. A change in crustal p wave velocity at about 60 km from the deformation front (or 70 km from the southern coast of the Dominican Republic) is interpreted to be the boundary between the arc crust and the accretionary prism. Caribbean oceanic crust does not appear to extend farther north. We interpret the results to indicate limited overthrusting of the Caribbean slab in the muertos Trough, rather than subduction.

    1981-01-01

    A 2-year study of the aquatic biota in the Redwood Creek and Mill Creek drainage basins of Redwood National Park indicated that the aquatic productivity is low. Densities of coliform bacteria were low except in Prairie Creek, a tributary to Redwood Creek, where a State park, county fish hatchery, grazing land, lumber mill, and scattered residential areas are potential sources of fecal coliform bacteria. Benthic invertebrate data indicated a diverse fauna which varied considerably between streams and among stream sections. Noteworthy findings include: (1) benthic invertebrates rapidly recolonized the streambed following a major storm, and (2) man-caused disruption or sedimentation of the streambed during low flow can result in drastic reductions of the benthic invertebrate community. Seven species of fish representing species typically found in northern California coastal streams were captured during the study. Nonparametric statistical tests indicate that condition factors of steelhead trout were significantly larger at sampling stations with more insolation, regardless of drainage basin land-use history. Periphyton and phytoplankton communities were diverse, variable in numbers, and dominated by diatoms. Seston concentrations were extremely variable between stations and at each station sampled. The seston is influenced seasonally by aquatic productivity at each station and amount of allochthonous material from the terrestrial ecosystem. Time-series analysis of some seston data indicated larger and sharper peak concentrations being flushed from the logged drainage basin than from the control drainage basin. (USGS)

  7. Geological and geochemical reconnaissance in the central Santander Massif, Departments of Santander and Norte de Santander, Colombia

    USGS Publications Warehouse

    Evans, James George

    1976-01-01

    The central Santander Massif is composed of Precambrian Bucaramanga Gneiss and pre-Devonian Silgara Formation intruded by Mesozoic quartz diorite, quartz monzonite, and alaskite and Cretaceous or younger porphyry. Triassic (Bocas Formation), Jurassic (Jordan and Giron Formations).and Cretaceous (Tambor, Rosa Blanca, Paja, Tablazo, Simiti, La Luna, and Umir Formations) sedimentary rocks overlie the metamorphic rocks and are younger than most of the intrusions. A geological and geochemical reconnaissance of part of the central Santander Massif included the Vetas and California gold districts. At Vetas the gold is generally in brecciated aphanitic quartz and phyllonite. Dark-gray material in the ore may be graphite. The ore veins follow steep west-northwest- and north-northeast-striking fracture zones. No new gold deposits were found. Additional geochemical studies should concentrate on western Loma Pozo del Rey and on improvement of the gold extraction process. At California the gold is in pyritiferous quartz veins and quartz breccia. Ore containing black sooty material (graphite?) is highly radioactive. Some of the mineralization is post-Lower Cretaceous. Soil samples indicate that gold deposits lie under the thick blanket of soil on the ridges above the zone of mining. Three principal gold targets are outlined by gold and associated minerals in pan concentrates. The close relation of gold and copper anomalies suggests that copper may be useful as a pathfinder for gold elsewhere in the region. Based on occurrences of gold or high concentrations of pyrite or chalcopyrite in pan concentrates and on analytical data, eight potential gold targets are outlined in the central massif. Reconnaissance of the surrounding region is warranted.

    PSR J1417-4402 was detected when the binary system to which it belongs switched from an X-ray source to a pulsar state. The characteristic parameters of this binary system put it out of the Redback family, in which some of their members experienced such a change. This behaviour was not expected in this kind of systems. However, it is a natural result in the frame of our close binary systems models with irradiation feedback. We present a possible progenitor to this system.

    We use a mass complete sample of galaxies with accurate photometric redshifts in the COSMOS field to estimate the density field and to extract the components of the cosmic web. The comic web extraction algorithm relies on the signs and the ratio of eigenvalues of the Hessian matrix and is enable to integrate the density field into clusters, filaments and the field. We show that at z < 0.8, the median star-formation rate in the cosmic web gradually declines from the field to clusters and this decline is especially sharp for satellite galaxies (~1 dex vs. ~0.4 dex for centrals). However, at z > 0.8, the trend flattens out. For star-forming galaxies only, the median star-formation rate declines by ~ 0.3-0.4 dex from the field to clusters for both satellites and centrals, only at z < 0.5. We argue that for satellite galaxies, the main role of the cosmic web environment is to control their star-forming/quiescent fraction, whereas for centrals, it is mainly to control their overall star-formation rate. Given these, we suggest that most satellite galaxies experience a rapid quenching mechanism as they fall from the field into clusters through the channel of filaments, whereas for central galaxies, it is mostly due to a slow quenching process. Our preliminary results highlight the importance of the large-scale cosmic web on the evolution of galaxies.

    In order to investigate the behavior of Fe II lines in Be stars, we carry out a statistical analysis over a sample of IUE images. We found that only 4 of the 39 studied stars (with spectral types B2, B5 and B8) show Fe II lines. Synthetic spectra of Fe II lines were computed by means of a rigorous treatment of the line transfer equation for moving flows, considering different effective temperature, velocity and temperature structure. Preliminary results show that the shape of the profiles depends mainly on the velocity structure, while the intensity changes with both the temperature and the density structure.

  17. Los mitos como memoria colectiva de Los Pueblos.

    NASA Astrophysics Data System (ADS)

    Martín, P. T.

    Myths are essentially something practical that allows those who believe in them to solve any ambiguity which could come up in their relation with nature. Since they bring information about the condition of the reality to which they belong, they are but the appropriate instrument to insert nature into culture by actually achieving an adaptation to the environment. The purpose of this essay is to show how the deification of plants, animals, and stars, which are present in the daily lives of "Amerindian" people, not only constitutes a source of rich mythology but also turns out to be an effective measure towards the continuity of social groups. Similarities or identifications between human life and the life of plants, animals and stars as well as mutual interplay are somehow present in those myths: stars which create or are changed into human being, animals or plants; human beings who create or are transformed into astral bodies; battles between peoples and stars, etc. On this base, mythology can provide not only keys to show how certain human groups have achieved their adaptation to the environment and how the different social systems and their relations to nature have developed, but also hints of changes which have taken place in other heavenly spheres such as the falling of meteors, the appearance of comets or any other significant events of this kind in the lives of these groups.

    Resumen Antecedentes La presencia de metástasis en los ganglios linfáticos (MGL) en la prostatectomía radical de rescate (PRs) se asocia con un mal pronóstico. Los factores predictivos de resultados en este contexto siguen siendo indeterminados. El objetivo fue evaluar el papel de número de ganglios linfáticos positivos sobre el resultado de los pacientes con MGL después de PRs y para el cáncer de próstata de radio-recurrente. Material y métodos Se analizaron los datos de una cohorte consecutiva de 215 hombres tratados con PRr en una sola institución. Se utilizaron los modelos de regresión de riesgos proporcionales de Cox univariante para la recurrencia bioquímica (RBQ) y los resultados metastásicos, con el antígeno prostático específico, la puntuación de Gleason, la extensión extraprostática, la invasión de vesículas seminales, el tiempo entre la terapia de radiación y PRr y el número de ganglios positivos como factores predictivos. Resultados De los 47 pacientes con MGL, 37 desarrollaron RBQ, 11 desarrollaron metástasis a distancia y 4 fallecieron con una mediana de seguimiento de 2,3 años para los supervivientes. El riesgo de metástasis aumentó con mayores niveles preoperatorios de PSA (HR 1,19 por 1 ng/ml; IC del 95%: 1,06, 1,34; p = 0,003). Los factores predictivos restantes no alcanzaron niveles convencionales de significación. Sin embargo, la eliminación de 3 o más ganglios linfáticos positivos demostró una asociación positiva, como se esperaba, con enfermedad metastásica (HR 3,44, IC: 0,91, 13,05; p = 0,069) en comparación con uno o dos ganglios positivos. Del mismo modo, la presencia de extensión extraprostática, invasión de vesículas seminales y grado de Gleason superior a 7 también demostraron una asociación positiva con un mayor riesgo de metástasis, con índices de riesgo de 3,97 (IC del 95% 0,50; 31,4; p = 0,2), 3,72 (IC 95% 0,80, 17,26; p = 0,1) y 1,45 (IC del 95% 0,44, 4,76; p = 0,5), respectivamente

    Atypical clinical manifestations have been observed in newborns and infants suffering from fever caused by the chikungunya virus. Objective: To describe the cases of fever caused by the chikungunya virus in newborns and infants with atypical mucocutaneous lesions. Materials and methods: We reviewed the clinical records, as well as lab tests and histopathological results, of newborns and infants diagnosed with Chikungunya virus and atypical mucocutaneous lesions in three regional hospitals. Results: Out of 18 suspected cases of chikungunya virus in newborns and infants, 11 were positive and presented atypical mucocutaneous manifestations. Six of the eleven confirmed cases corresponded to children under five months of age. The most common symptoms were fever, skin rash, irritability, and diarrhea. Three of the patients were infected with both dengue and chikungunya viruses. The ulcers occurred in the scalp, abdomen, genital and perianal region. We report mucocutaneous manifestations in newborns and infants diagnosed with fever caused by the chikungunya virus in Colombia. The rapid development of ulcers is most likely due to the immune response to the virus. Special attention should be given to pregnant women presenting symptoms of chikungunya virus infection prior to delivery, and their offspring should be followed-up in order to monitor possible complications.

    Laser probe {sup 40}Ar/{sup 39}Ar analyses of individual sanidine grains from four tuffs in the alluvial Late Cretaceous (Campanian) El Gallo Formation yield statistically distinct mean dates ranging from 74.87 {plus minus} 0.05 Ma to 73.59 {plus minus} 0.09 Ma. The exceptional precision of these dates permits calculation of statistically significant sediment accumulation rates that are much higher than passive sediment loading would cause, implying rapid tectonically induced subsidence. The dates bracket tightly the age of important dinosaur and mammalian faunas previously reported from the El Gallo Formation. The dates support an age less than 73 Ma for the Campanian/Maastrichtian stage boundary, younger than indicated by several currently used time scales. Further application of the single grain {sup 40}Ar/{sup 39}Ar technique may be expected to greatly benefit stratigraphic studies of Mesozoic sedimentary basins and contribute to calibration of biostratigraphic and magnetostratigraphic time scales.

    Objectives. We assessed the impact of a tobacco control initiative over 10 years on cessation and prevention. Methods. We examined 2000–2009 Behavioral Risk Factor Surveillance System cases of a metropolitan statistical area (MSA) with systematic tobacco control efforts throughout the decade (El Paso, TX) and 2 comparison MSAs similar in size and population with less coordinated tobacco control efforts (Austin-Round Rock, TX and San Antonio, TX). Results. Yearly, El Paso exhibited a 6% increase in the prevalence of former smokers, a 6% decrease in prevalence of daily smokers, and a 7% decrease in the prevalence of established smoking (≥ 100 cigarettes per lifetime and currently smoking); we did not observe similar trends in the comparison MSAs. There was no change in the prevalence of nondaily smokers in any of the MSAs. Conclusions. The coordinated tobacco control activities in El Paso are related to cessation among daily smokers and prevention of established smoking at the population level but have not stimulated cessation among nondaily smokers. Comprehensive tobacco control should focus more on not only daily smokers but also nondaily smokers. PMID:22494000

    An interdisciplinary study has been undertaken in Redwood National Park, Calif., to describe parts of the ecosystems and recent changes in the intensity of erosion and sedimentation, define processes that may alter the natural ecosystems, and assess the impact of recent road construction and timber harvest. This report is the second of a series that will present data collected in this study. Stream-discharge and water-quality data were collected at 53 sampling stations in the Redwood Creek and Mill Creek drainage basins. Measurements included the following variables: Stream stage and discharge; turbidity; sediment; onsite water-quality determinations of temperature, pH , total alkalinity, specific conductance, and dissolved-oxxygen concentration; chemical analyses of water samples for major dissolved solids, selected trace elements, nitrogen, phosphorus, and organic carbon; chemical analyses of bottom sediment for organic carbon and pesticides; bacteria; benthic invertebrates; fish; periphyton; phytoplankton; and seston. Additional data include changes in geometry at 10 stream-channel cross sections along Mill Creek and the distribution of erosional landforms in the Mill Creek drainage basin; quantity and chemical composition of rainwater; and the intragravel-streambed condition at selected stations in the Redwood Creek drainage basin.

    Recent collections of the Asian fish tapeworm Bothriocephalus acheilognathi in the Rio Grande have raised concern about the potential impacts on Rio Grande endemic and imperiled fishes. The objectives of this study were to determine distribution and definitive hosts of the Asian fish tapeworm within the Rio Grande drainage and to quantify occurrences and abundances. In total, 1,992 fish spanning 11 families were collected and examined for Asian fish tapeworms in the Rio Grande and the Pecos and Devils rivers. The parasite was collected from red shiners Cyprinella lutrensis, Tamaulipas shiners Notropis braytoni, sand shiners N. stramineus, river carpsuckers Carpiodes carpio, plains killifish Fundulus zebrinus, western mosquitofish Gambusia affinis, blue suckers Cycleptus elongatus, blacktail shiners Cyprinella venusta, proserpine shiners Cyprinella proserpina, and Manantial roundnose minnow Dionda argentosa, with the latter four species being new host records. Monthly collections of red shiners from Big Bend National Park exhibited prevalence levels above 15% in January-March and December and below 10% during April-June and October. With over 50% of the Rio Grande icthyofauna in Texas considered imperiled, the occurrence and pathological effects of the Asian fish tapeworm in combination with reduced water quantity and quality and increased habitat fragmentation are of concern for these taxa.

    Marine Protected Areas (MPAs) are world-wide established with the aim of conserving biodiversity and preventing overexploitation of marine organisms. Evaluating the effectiveness of MPAs is needed in order to support and implement their management, but it is complicated by the large natural variability in space and time of distribution and abundance of natural populations. Here, we tested the hypothesis that patterns of total abundance and size-frequency distribution of two intensively harvested intertidal species (the sea urchin Paracentrotus lividus and the mussel Mytilus galloprovincialis) differed between a protected and three reference shores along the rocky coast of north Portugal. Response variables were in terms of mean values and measures of variance at different spatial scales (from centimetres to metres) and over time (along a period of about 12 months). A further comparison involved the estimation of the reproductive potential of sea urchins, quantified as variations of Gonad Index (GI = gonad dry weight/body dry weight × 100) at the scale of shore. Results did not generally support a predictable direct effect of protection, as the total abundance and the abundance of larger individuals of both species and GI did not differ between the MPA and reference shores. However, a considerable temporal and spatial variability at smaller scales was detected for several response variables. Such findings have implications for management of MPAs, highlighting the need for sampling designs properly replicated in space and time, in order to examine their effectiveness, and for considering spatial and temporal heterogeneity of target populations and driving processes as a criterion for their implementation and design.

    Objetivo: Revisar y discutir la información más reciente sobre el valor agroindustrial, funcional y nutricional de uno de los frutos de mayor cultivo, exportación y consumo en México: el Mango. Métodos: Se realizó una búsqueda en diversas bases de datos (PubMed, Cochrane, ScienceDirect) y documentos de libre acceso (Google Scholar) sobre Mangifera indica L. Esta información fue posteriormente sub-clasificada en aspectos agroindustriales, nutricionales, funcionales y efectos a la salud. Resultados: Uno de cada veinte mangos consumidos mundialmente, es mexicano. “Ataulfo” es la variedad la de mayor importancia agronómica. El procesamiento mínimo de su pulpa (MP) genera residuos de cáscara (MC) y semilla con alto potencial nutracéutico. MP y MC son buenas fuentes de ascorbato, fructosa, fibra dietarias soluble (MP, almidones y ramnogalacturonanos) e insoluble (MC, ligninas y hemicelulosa) y lípidos funcionales (MP). MP y MC poseen un perfil de compuestos fenólicos (CF) monoméricos (MP) como el acido gálico y el protocatehuico y poliméricos (MC) como la -PGG asociados con efectos anti-obesigénicos, anti-inflamatorios, anti-cancerigenos y anti-diabeticos. Estos beneficios son dependientes de la bioaccesibilidad (liberación de su matriz alimentaria) y destino metabólico (biodisponibilidad) de estos CF. Discusión: El mango resulta una valiosa fuente de compuestos antioxidantes con comprobado beneficio a la salud. Sin embargo, factores como la variedad, temporalidad de cultivos, tratamientos pre y post-cosecha, extracción de bioactivos y algunas barreras fisiológicas pueden modificar su potencial nutracéutico.

    2010-01-01

    La historia de la migración México-Estados Unidos se caracteriza por una serie de periodos durante los cuales los patrones migratorios se transforman y evolucionan como respuesta a los cambios en la política migratoria de Estados Unidos. En la década de 1990 se dio uno de estos cambios, lo que provocó el paso de la ‘era de la contradicción’ a la ‘era de la marginalización’. Actualmente, un gran número de migrantes indocumentados permanecen al margen de la ley, precisamente en un periodo en el que las penas se han incrementado y la persecución ha alcanzado niveles récord. De manera cada vez más notoria, los migrantes indocumentados, por la represión interna y fronteriza, quedan obligados a romper los lazos que los vinculaban con sus lugares de destino, pero al mismo tiempo se sienten cada vez más extraños en una tierra donde la aplicación de políticas antiinmigrantes es cosa de todos los días, lo que los sitúa en una posición de marginalización y gran vulnerabilidad.

    Rural women in Southern Mexico link their diabetes to distressful life experiences rooted in ordinary violence. While much has been written on the use that diabetes sufferers make of their morbid condition as an idiom of distress, I investigate the personal and social effects that such an idiom has on women. As I illustrate, diabetes reflects an ambivalence that helps women to speak about the unspeakable and, at the same time, reinforces their ideas of culpability, namely that they are to blame for both the gendered violence that they endure and the diabetes from which they suffer.

    Background Despite the high prevalence of co-morbid substance use among mental health service users (dual diagnosis), very few mental health workers in the UK have had training and/or clinical experience to equip them to deliver targeted interventions to this client group. Method In a randomised controlled trial of training for dual diagnosis interventions, 79 case managers from 12 community mental health teams in South London were randomly allocated to either receive training and follow-up supervision (experimental group) or no training and supervision (control group). Baseline measures of attitude, self-efficacy and knowledge were collected prior to randomisation, and were repeated at 18 months post-training. An intention to treat analysis of follow-up data (adjusted for baseline score for that outcome and team) was performed. Results At 18 months post-training, the AAPPQ (The Alcohol and Alcohol Problems Perception Questionnaire) total score was did not differ significantly between the two groups (adjusted difference 7.43 [95% CI -0.86 to 15.71], p = 0.08). There were significant differences in favour of the experimental group on 2 of the 6 subscales of the AAPPQ: 'adequacy of knowledge and skills in working with alcohol" (adjusted difference 3.598 [95% CI 1.03 to 6.16], p = 0.007) and "self-esteem in working with alcohol" (adjusted difference 3.00 [95% CI 0.46 to 5.54], p = 0.021). In addition there were significant improvements for the experimental group on "Knowledge About Dual Diagnosis" (adjusted difference 2.00 [95% CI 0.80 to 3.22], p = 0.002) and "Self-Efficacy Scale" (adjusted difference 13.55 [95% CI 8.00 to 26.86], p = 0.001). The effect of membership of teams was added to the analysis of covariance and this changed the results for only one variable: "self-esteem working with drinkers" was no longer significant. Conclusion A brief training course in dual diagnosis interventions had a significant effect on secondary measures of knowledge and self-efficacy that was detectable at 18 months post-training. Improvements in attitudes towards working with drinkers and drug users in mental health settings failed to reach statistical significance. Future research should explore the effects of dose of dual diagnosis training, and the successful integration of skills gained into routine care.

  14. Contributions of local knowledge to the physical limnology of Lake Como, Italy.

    Laborde, Sarah; Imberger, Jörg; Toussaint, Sandy

    2012-04-24

    This article shows how local knowledge may be valuably integrated into a scientific approach in the study of large and complex hydrological systems where data collection at high resolution is a challenge. This claim is supported through a study of the hydrodynamics of a large lake where qualitative data collected from professional fishers was combined with theory to develop a hypothesis that was then verified by numerical modeling. First the fishermen's narratives were found to describe with accuracy internal wave motions that were evident in water column temperature records, which revealed their practical knowledge of the lake's hydrodynamics. Second, local knowledge accounts emphasized the recurrent formation of mesoscale gyres and return flows in certain zones of the lake in stratified conditions, which did not appear in the physical data because of limitations of sampling resolution. We hypothesized that these features developed predominantly because of the interaction of wind-driven internal motions with the lake's bathymetry, and the Earth's rotation in the widest areas of the basin. Numerical simulation results corroborated the fishers' descriptions of the flow paths and supported the hypothesis about their formation. We conclude that the collaboration between scientific and local knowledge groups, although an unusual approach for a physical discipline of the geosciences, is worth exploring in the pursuit of a more comprehensive understanding of complex geophysical systems such as large lakes.

    2015-10-01

    An efficient electrocatalyst comprising inexpensive and earth-abundant materials for the oxygen evolution reaction (OER) is crucial for the development of water electrolysis. In this work, in-situ addition of cobalt/molybdenum ions to the electrolytic manganese dioxide has been shown to be beneficial for the OER in acid solution as its overpotential performed better (305 mV) than that of the commercial DSA® (341 mV) at 100 mA cm-2. The OER was investigated at ambient temperature in 2 M H2SO4 solution on the modified EMD (MnMoCoO) electrodes. The energy efficiency of the MnMoCoO electrodes improved significantly with the amount of Co in the plating solution. For the electrodeposited catalysts, physico-chemical and electrochemical measurements were conducted including static overpotentials. The better performance of the modified EMD was attributed to an improved charge transfer resistance (Rct; 0.290 Ω cm2), average roughness factor (rf; 429) and decrease in water content in the electrodeposited catalysts. The kinetic parameters obtained on MnMoCoO catalysts were compared and discussed according to the cobalt concentration.

  13. Understanding Changes in Water Availability in the Rio Grande/Rio Bravo del Norte Basin Under the Influence of Large-Scale Circulation Indices Using the Noah Land Surface Model

    NASA Technical Reports Server (NTRS)

    Khedun, C. Prakash; Mishra, Ashok K.; Bolten, John D.; Beaudoing, Hiroko K.; Kaiser, Ronald A.; Giardino, J. Richard; Singh, Vijay P.

    2012-01-01

    Water availability plays an important role in the socio-economic development of a region. It is however, subject to the influence of large-scale circulation indices, resulting in periodic excesses and deficits. An assessment of the degree of correlation between climate indices and water availability, and the quantification of changes with respect to major climate events is important for long-term water resources planning and management, especially in transboundary basins as it can help in conflict avoidance. In this study we first establish the correlation of the Pacific Decadal Oscillation (PDO) and El Nino-Southern Oscillation (ENSO) with gauged precipitation in the Rio Grande basin, and quantify the changes in water availability using runoff generated from the Noah land surface model. Both spatial and temporal variations are noted, with winter and spring being most influenced by conditions in the Pacific Ocean. Negative correlation is observed at the headwaters and positive correlation across the rest of the basin. The influence of individual ENSO events, classified using four different criteria, is also examined. El Ninos (La Ninas) generally cause an increase (decrease) in runoff, but the pattern is not consistent; percentage change in water availability varies across events. Further, positive PDO enhances the effect of El Nino and dampens that of La Nina, but during neutral/transitioning PDO, La Nina dominates meteorological conditions. Long El Ninos have more influence on water availability than short duration high intensity events. We also note that the percentage increase during El Ninos significantly offsets the drought-causing effect of La Ninas.

    There were no statistically significant differences between the stream velocities associated with seine hauls of the Rio Grande silvery minnow and Tamaulipas shiner. Stream velocities associated with the seine hauls that included Rio Grande silvery minnow indicate that this species is predominantly found in low-velocity mesohabitats. Velocities associated with seine hauls that included the Tamaulipas shiner represented a much broader overall range of velocities than those associated with Rio Grande silvery minnow collections. No statistically significant differences were found between the depths for seine hauls that included Rio Grande silvery minnow or Tamaulipas shiner. The Rio Grande silvery minnow was more commonly collected in seine hauls from mesohabitats dominated by cobble substrates and less frequently collected in mesohabitats with substrates dominated by fine-sized silt and clay particles, gravels, and sands, in that order. In contrast, the Tamaulipas shiner was broadly distributed among mesohabitats characterized as having gravel, cobble, and silt and clay.

    Se presenta un mapa geologico digital de Venezuela sobre un fondo de relieve sombreado. Los datos geologicos e hidrologicos del norte del rio Orinoco proceden de la digitalizacion de mapas geologicos en papel a escala 1:500.000. Estos datos fueron integrados con el mapa geologico digital del Escudo de Guayana Venezolano, a su vez derivado de hojas en papel a escala 1:500.000. La informacion sobre los tipos de fallas mostrados en el mapa es igual que en las fuentes originales. Los poligonos geologicos fueron atribuidos por edad, litologia y nombre de la unidad siguiendo el Codigo geologico de Venezuela. Se incorporaron revisiones significativas de la geologia de la Cordillera de la Costa a partir de las nuevas hojas integradas a escala 1:25.000. Toda esta informacion geologico-estructural se sobrepuso a una imagen de relieve sombreado, producida por el procesamiento de los datos de radar interferometrico con 90 m (3 arcosegundos) de resolucion espacial obtenidos por la mision topografica de radar del transbordador espacial (SRTM). Las areas de la base de datos del SRTM carentes de informacion fueron llenadas por medio de la interpolacion de los datos de las celdas adyacentes. Para producir la imagen de relieve sombreado se uso una direccion de iluminacion de 315 deg con un angulo de 65 deg sobre el horizonte. La proyeccion usada en el mapa es conica equidistante, con latitudes de 4 y 9 deg norte como paralelos estandar y una longitud de 66 deg al oeste como meridiano central. Los datos en el mapa proceden primordialment de hojas a escala 1:500.000 y el producto esta preparado para una impresion optima en escala 1:750.000. Los usuarios pueden obtener ampliaciones mayores, sin embargo no se garantiza la precision del mapa a escalas mas detalladas. Especialmente en la region de Guayana, al sobreponer los mapas geologicos sobre la reciente imagen SRTM, se notan grandes discrepancias no sistematicas tanto en contactos como en fallas. Esto es debido a que los mapas

    Objetivo: El propósito de este artículo es la evaluación cualitativa extensa de Chishao. Métodos: En el experimento de este trabajo, se establecen los espectros de identificación de Chishao en todas las localizaciones mediante RP-HPLC y el método del análisis de componentes principales con las áreas pico de RPHPLC. Resultados: La calidad de Chishao en el norte de China o del procedente de Paeonia lactiflora es mejor que la de otras localizaciones o procedente de P. obovata, P. mairei y P. anomala. Los resultados son congruentes con la impresión tradicional de la calidad de esta planta. Estos resultados indican que el análisis de los componentes principales (ACP) puede utilizarse como método eficaz y económico para evaluar la calidad de Chishao y podría aplicarse a otras plantas medicinales chinas. Conclusiones: Dada la complicada base de la eficacia de la Medicina tradicional china (MTC), un método como el ACP para diversos componentes químicos parece ser más adecuado para la evaluación de la calidad de la MTC en comparación con la determinación de un único o unos pocos agentes químicos.

    Objetivo. Conocer la incidencia poblacional de la hemorragia intracerebral y su incidencia evitable, factores de riesgo asociados y pronostico de muerte y discapacidad. Sujetos y metodos. Muestra de 240 pacientes consecutivos con un primer episodio de hemorragia intracerebral entre el 1 de abril de 2006 y el 30 de junio de 2015. Las variables principales son: escala NIHSS, comorbilidad, informacion farmacologica, indice de Barthel, escala de Rankin, tiempo en rango terapeutico, pronostico y destino al alta hospitalaria. Se aplico la clasificacion 'mortalidad innecesariamente prematura y sanitariamente evitable' (MIPSE) para definir los casos como 'incidencia evitable'. Resultados. La tasa de incidencia poblacional de enfermedad cerebrovascular hemorragica fue de 23,5 casos por 100.000 habitantes/año; se produjo un incremento exponencial a partir de los 55 años en hombres y 75 años en mujeres. La razon de tasas fue de 0,682. La incidencia evitable significaria el 66,6% de todos los casos en los menores de 75 años y el 22,7% en aquellos con 75 o mas años. La probabilidad de supervivencia y la autonomia funcional fueron significativamente inferiores en las mujeres, y la edad, el tratamiento anticoagulante, la presencia de polimedicacion y el tratamiento con antidepresivos inhibidores de la recaptacion de serotonina fueron factores independientes del pronostico. Conclusiones. No parece que se modifique la incidencia de enfermedad cerebrovascular hemorragica en el periodo, pero si los factores asociados segun sexo y edad. Segun la clasificacion MIPSE, la evitabilidad de la enfermedad cerebrovascular hemorragica seria de hasta un 36%.

    Astronomy is considered among the first sciences that man dominated, however, the basic skills for the construction of knowledge, relatively to the contents "Earth and the Universe" are not being developed properly for the majority of students concluding the high school level. The students are concluding this teaching cycle without proper knowledge of several subjects in the area of Astronomy, which are mandatory in the national Curricular National Parameters (PCN). Because of this discrepancy, this work stresses the need of the incorporation of a specific subject of Astronomy in the high school, in order to reduce the gap between what is taught and which should be taught. La Astronomía es considerada una de las primeras ciencias que el hombre dominó. Sin embargo, las habilidades básicas para la construcción del conocimento, relativo al eje temático "Tierra y Universo", no vienen siendo trabajadas adecuadamente con la mayoría de los alumnos que concluyen el ciclo escolar medio. Los alumnos están concluyendo este nivel de enseñanza sin conocimentos de varios temas en el área de Astronomía, que son obligatorios según los Parámetros Curriculares Nacionales (PCN). En virtud de esta discrepancia, este trabajo enfatiza la necesidad de incorporar una disciplina específica de Astronomía em el ciclo medio, em pro de la reducción de las distorsiones entre lo que es enseñado y lo que se debe enseñar.

    Kimura, Nobuharu; Iwanami, Yoshimu; Koide, Ryutaro; Kudo, Reiko

    2017-06-01

    When a mixture of light gas oil (LGO) and light cycle oil is fed into an oil refinery’s hydrodesulfurization (HDS) unit to produce diesel fuel, the catalyst in the HDS unit is rapidly deactivated. By contrast, when the feed is LGO mixed with residue desulfurization gas oil, the catalyst is deactivated slowly. Hoping to understand why, the authors focused on the coke formed on the catalysts during the HDS reaction. The result of a comprehensive analysis of the coke suggested that the ways coke formed and grew on the catalysts may differ depending on the feeds used, which in turn could affect the deactivation behaviors of the catalysts.

    Introduccion. El sindrome de apnea obstructiva del sueño (SAOS) es una enfermedad frecuente, compleja y poligenica, con diversas etiologias que interaccionan originando un fenotipo unico. El SAOS puede ocurrir a cualquier edad del individuo y se presume la existencia de agregacion familiar. Han sido descritos diversos factores de predisposicion, como la edad, el sexo y la obesidad. La relacion entre los polimorfismos del antigeno leucocitario humano (HLA) y trastornos del sueño esta confirmada, tanto en poblaciones europeas como no europeas. No obstante, las relaciones descritas entre los alelos HLA y SAOS no han sido coherentes y carecen de valor informativo para la clasificacion del trastorno del sueño. Objetivo. Explorar la asociacion genetica del HLA con el SAOS en una poblacion del norte de Portugal y evaluar el papel de la obesidad en el contexto del HLA en el SAOS. Pacientes y metodos. Se estudio una cohorte de 131 pacientes con SAOS. Los pacientes fueron atendidos en una clinica del sueño ambulatoria donde se valoraron los antecedentes clinicos, se les practico una polisomnografia nocturna, una prueba de latencia multiple del sueño (si lo exigio el diagnostico diferencial), analiticas y estudios demograficos. A efectos comparativos, se utilizo una poblacion de control de 223 personas sanas. Se efectuo el genotipado del HLA-DRB1 con la reaccion en cadena de la polimerasa mediante cebadores de secuencia especifica. Resultados. En esta cohorte, el alelo HLA-DRB1*03 fue identificado como un factor de predisposicion para el SAOS (24% del SAOS frente a 15% de la poblacion de control; p = 0,025; odds ratio = 1,861; intervalo de confianza al 95% = 1,081-3,205). No hubo diferencias significativas en lo referente a otros alelos HLA-DBR1*. Conclusion. El HLA-DRB1*03 es un factor de predisposicion para el SAOS en la poblacion portuguesa.

  18. Puerto Rico, humedales [Puerto Rico, wetlands

    USGS Publications Warehouse

    Adams, D. Briane; Hefner, John M.; Dopazo, Teresa

    1999-01-01

    La isla de Puerto Rico, localizada al noreste del Mar Caribe y sus islas principales, Vieques, Culebra e Isla de Mona, poseen humedales en abundancia . El clima subtropical, la lluvia abundante y las complejas formas topográficas y geológicas de estas islas dan origen a los humedales, que varían desde los raros e inusuales bosques cubiertos por nubes en las tierras altas, hasta los extensos manglares, yerbas marinas y arrecifes de coral a lo largo de las costas Norte y Sur. Sin embargo, los humedales en Puerto Rico han disminuido en los últimos siglos como resultado del aumento en el desarrollo agrícola, poblacional y turístico. Algunos tipos de humedales como los bosques de palo de pollo (Pterocarpus officinalis) se han reducido a sólo unos pocos remanentes (figura 1).Biológicamente hablando, los humedales de las islas están entre las áreas más productivas. Los humedales asociados con el bosque pluvial en las tierras altas del interior de Puerto Rico contienen varias plantas raras y especies de animales que no se encuentran en otras partes de la Isla. El agua de escorrentía proveniente de los humedales en las partes altas de la Isla proveen una fuente de agua que utilizan varias ciudades para abasto público. Los humedales costeros como los mangles, los colchones de yerbas marinas y los arrecifes de coral proveen áreas para la reproducción y crianza de varios peces, crustáceos y otras especies en la cadena alimenticia (López y otros, 1988). De esta manera, los humedales costeros contribuyen a la productividad biológica de las aguas llanas del mar alrededor de las islas . Los humedales también estabilizan las costas atrapando y reteniendo sedimentos no consolidados y amortiguan la acción de las olas y de las tormentas que tienen el potencial de causar daños en la zona.El valor de los humedales de Puerto Rico para la vida silvestre está muy bien documentado . Por ejemplo, las salinas de Cabo Rojo, en la costa suroeste, proveen áreas para el

    Introducción: El control del nivel de práctica de actividad física que realizan los adolescentes, de sus factores determinantes y susceptibilidad al cambio resulta indispensable para intervenir sobre la epidemia de obesidad que afecta a la sociedad española. Sin embargo, el número de cuestionarios validados para valorar la actividad física en adolescentes españoles es escaso. Objetivos: Evaluar la validez del cuestionario24hPrevious Day Physical Activity Recall (PDPAR-24) cuando es aplicado a la población de adolescentes españoles. Método: Participaron en este estudio estudiantes de 14-15 años de dos centros de educación secundaria del norte de Galicia. Como criterio objetivo de la actividad física realizada se utilizó el registro proporcionado por el acelerómetro Actigraph GT3X.Se monitorizó a los sujetos durante un día por medio del acelerómetro y al día siguiente se administró el cuestionario de auto-informe. Resultados: Un total de 79 alumnos (15.16 ± 0.81 años, 39% mujeres) finalizaron el estudio. Se observan correlaciones positivas estadísticamente significativas de tamaño medio a grande en ambos sexos (r=0.50-0.98), para la actividad física ligera y moderada. Las correlaciones observadas son más elevadas a medida que aumenta la intensidad de la actividad física realizada. Conclusiones: El cuestionario de auto-informe PDPAR-24 puede ser considerado como una herramienta válida a la hora de valorar el nivel de actividad física en adolescentes españoles.

    Introdução: A diabetes mellitus e a hipertensão arterial são problemas de saúde de elevada prevalência em Portugal. A sua distribuição geográfica e social é pouco conhecida, comprometendo o desenho e implementação de políticas de saúde. Assim, este estudo teve como objetivo avaliar a existência das desigualdades socioeconómicas na prevalência de diabetes mellitus tipo 2 e hipertensão arterial, na população residente na região Norte de Portugal, no ano de 2013. Material e Métodos: Foi realizado um estudo ecológico que analisou as 2 028 freguesias da região Norte. Os dados foram obtidos através do Sistema de Informação das Administrações Regionais de Saúde e do Censos 2011. A associação entre indicadores socioeconómicos e prevalência destas doenças foi medida pela diferença de prevalências, risco atribuível populacional, índice relativo de desigualdades e coeficiente de regressão. Resultados: A prevalência de diabetes mellitus tipo 2 e hipertensão arterial foi de 6,16% e de 19,35%, respetivamente, e variou entre freguesias. A prevalência de ambas as doenças associou-se significativamente com o baixo nível educacional, baixa atividade no sector terciário, desemprego e baixo rendimento (diferença de prevalências entre decis opostos até 1,3% e 5,3%). Os determinantes socioeconómicos foram responsáveis até 20% da prevalência na população. Discussão: Este tipo de estudo não permitiu a análise de causalidade e poderá ter subestimado as desigualdades socioeconómicas. Contudo, os resultados obtidos alinham-se com a evidência científica internacional. Conclusão: Estes resultados demonstram a existência de uma distribuição socioeconómica e geográfica heterogénea e a necessidade de criação de políticas de saúde que atuem nas freguesias menos favorecidas.

    Abstract Background At least 511 species of birds occur in the semiarid region of northeastern Brazil and many of them interact with human populations in a number of different ways, including their use in zootherapeutics and their links with local beliefs. Objective The present work examined these types of birds/human interactions (use in zootherapeutics and their links with local beliefs) in the semiarid region of Rio Grande do Norte State in northeastern Brazil. Methods Information was obtained through semi-structured interviews with 120 local residents. Results A total of 16 wild bird species distributed among 11 families were found to interact directly with humans, with Columbidae being the best represented family. Seven species were identified in the medicinal category, five were related to symbolic aspects, while four species were identified as being related to both categories (medicinal and symbolic). Conclusion The accumulated folk knowledge, beliefs, and practices involving the avifauna in the semiarid region of Brazil, whether symbolic or medicinal, demonstrated the cultural importance of this vertebrate group to local human populations and revealed a belief system intrinsically related to cynegetic practices in the region.

    The presence of institutions on the internet is nowadays very important to strenghten communication channels, both internal and with the general public. The Córdoba Observatory has several web portals, including the official web page, a blog and presence on several social networks. These are one of the fundamental pillars for outreach activities, and serve as communication channel for events and scientific, academic, and outreach news. They are also a source of information for the staff, as well as data related to the Observatory internal organization and scientific production. Several statistical studies are presented, based on data taken from the visits to the official web pages. I comment on some aspects of the role of web pages as a source of consultation and as a quick response to information needs. FULL TEXT IN SPANISH

    Fuentes, Brenda O.; Mas, Francisco Soto; Mein, Erika; Jacobson, Holly E.

    2013-01-01

    Among Hispanic immigrants in the United States (US), learning English is considered necessary for economic and social achievement. As a consequence, there is a high demand for English as a Second Language (ESL) classes. Despite the recognized benefits of ESL programs, both at the individual and social levels, more research is needed to identify education strategies that effectively promote all aspects of learning English as a second language. This article describes an ESL curriculum that incorporates a theory-based pedagogical approach specifically designed for immigrant Hispanic adults on the US-Mexico border region. The article also describes the implementation of the curriculum as well as the results of the evaluation, which was conducted using both quantitative and qualitative methods. Quantitative results indicate that the participants significantly improved their English proficiency (L2). Qualitative results suggest that participants were positively impacted by both the content and pedagogical approaches used by the curriculum. Their experience with the ESL class was positive in general. It can be concluded that the curriculum achieved its objective. This approach could serve as a model for second language teaching for adults. PMID:25284915

    2015-01-01

    Abstract Background There is insufficient data concerning sarcopenia prevalence in South America. The aim of this study was to estimate sarcopenia prevalence and its clinical subgroups in a Southern Brazilian city. Methods A cross‐sectional population‐based study was performed among community‐dwelling elderly aged 60 years or over. Subjects were evaluated according to the European Working Group on Sarcopenia in Older People established criteria. Muscle mass was estimated by calf circumference (CC). Cut‐off CC points were defined by a subsample's dual X‐ray absorptiometry estimation of the appendicular skeletal muscle mass index (ASMI), which was subsequently compared with the values of a young adult population from the same city. Muscle strength was measured by manual dynamometry. Muscle performance was assessed through the 4 m gait speed test. Results The three diagnostic tests were performed in 1291 subjects. CC of ≤34 cm (males) and ≤33 cm (females) were defined as indicatives of low ASMI. The overall sarcopenia prevalence was 13.9% (CI95% 12.0; 15.8%). Its frequency was significantly higher among elderly with low schooling, without a partner, with low socioeconomic status, smokers, inactive, and with low body mass index. A higher prevalence of pre‐sarcopenia was found in the youngest elderly; a higher prevalence of the clinical stages of the syndrome was found in older age groups. Conclusions Approximately one in ten elderly aged 60–69 years was in the preclinical stage of the disease. This is the age group in which public policies should focus to establish early diagnosis and prevent clinical progression of the syndrome. PMID:27493867

    NASA Astrophysics Data System (ADS)

    Suarez, Rafael

    2003-11-01

    This thesis is concerned with the acoustic analysis of ecclesiastical spaces, and the subsequent implementation of acoustic design methodology in architectural renovations. One begins with an adequate architectural design of specific elements (shape, materials, and textures), with the intention of elimination of acoustic deficiencies that are common in such spaces. These are those deficiencies that impair good speech intelligibility and good musical audibility. The investigation is limited to churches in the province of Cordoba and to churches built after the reconquest of Spain (1236) and up until the 18th century. Selected churches are those that have undergone architectural renovations to adapt them to new uses or to make them more suitable for liturgical use. The thesis attempts to summarize the acoustic analyses and the acoustical solutions that have been implemented. The results are presented in a manner that should be useful for the adoption of a model for the functional renovation of ecclesiastical spaces. Such would allow those involved in architectural projects to specify the nature of the sound, even though somewhat intangible, within the ecclesiastical space.

    Using dual mesoporous titania as a support, due to the presence of intrinsic Brönsted acid sites, the main approach to 4,6-dimethylbenzothiophene (46DMDBT) hydrodesulfurization (HDS) becomes the direct desulfurization (DDS) route through isomerization and dismutation reactions, instead of the hydrogenation (HYD) pathway usually observed with a conventional promoted (by Ni or Co) MoS2/Al2O3 catalyst.

  11. How Have You Been? or ¿Como estás?: Does Language of Interview Influences Self-Rated Health Among Hispanic Subgroups?

    PubMed

    Santos-Lozada, Alexis R; Martinez, Matthew J

    2017-06-08

    This paper reports language differences in poor/fair self-rated health (SRH) among adults from six Hispanic groups in the United States. Data are from the cross-sectional 1997-2013 National Health Interview Survey (NHIS). The total sample of Hispanic adults with valid information for the variables considered in the study (n = 156,374) included Mexican-Americans (Mex-Am; n = 43,628), Mexicans (n = 55,057), Puerto Ricans (n = 14,631), Cubans (n = 8,041), Dominicans (from Dominican Republican, n = 4,359) and Other Hispanics (n = 30,658). We compared percentage of the population that reported poor/fair SRH among Hispanic individuals by language of interview and across origins using bivariate tests of association. Multivariable logistic regression analysis was used to study the odds of reporting poor/fair SRH based on language among the overall population and each group. Among the six Hispanic origins Puerto Ricans (15.92%), Cubans (16.36%) and Dominicans (15.32%) reported poor/fair SRH at higher levels than the overall sample (12.32%). In the logistic regression model adjusting potential covariates, those interviewed in Spanish were at higher odds of reporting poor/fair SRH than those interviewed in English (OR = 1.47, p < 0.0001). In the stratified analysis, Mexican-Americans were the only group where language of interview did not affect the odds of reporting poor/fair SRH. There are differences by Hispanic origin for reporting poor/fair SRH, and also by language of interview. Achieving accurate measurement of health status among Hispanics is a concern for all researchers, in particular those who study differences in health status by race/ethnicity in the United States. Future, research should account for Hispanic background and language of interviews.

    Advances in surgery and chemotherapy have improved the 5-year survival for patients with epithelial ovarian cancer, but have not impacted on the ultimate rate of cure in a disease that is diagnosed in late stage and that recurs in the majority of patients. "Omic" technologies promise to define genetically driven aberrant signaling pathways in malignant cells, provided that bioinformatic expertise can be focused on a cancer that is neither common nor rare. Molecular therapeutics must be linked to molecular diagnostics to permit individualized therapy. Not only epithelial cancer cells but also stroma, vasculature and the immune response must be targeted. Closer collaboration between academic institutions, biotech and pharma will be required to facilitate this process and to interest the private sector in an orphan disease. New preclinical models may permit more efficient development of drugs and siRNA that can target dormant drug resistant stem cells. Strategies must be developed to deal with the heterogeneity of different grades and histotypes. Identification of women at increased risk will facilitate prevention and early detection in subsets of patients. BRCA1/2 might be sequenced in all ovarian cancer patients to identify new kindreds. Epidemiologic algorithms are being developed and validated. Awareness must be raised that oral contraceptives can reduce risk of developing ovarian cancer by 50%. Early detection is likely to require panels of complementary biomarkers, analyzed by sophisticated statistical techniques, to improve sensitivity while maintaining extremely high specificity. As ovarian cancer becomes a chronic disease, greater emphasis will be placed on the challenges facing survivors.

    La astronomía gamma, en el extremo de energías detectadas hasta el presente, se encuentra en desarrollo en muchas partes del mundo y proporciona resultados sorprendentes a medida que la tecnología avanza en el desarrollo de nuevos detectores. La técnica Cherenkov Atmosférica es la utilizada para la detección, mediante telescopios en tierra, del efecto secundario causado por la radiación gamma de muy altas energías (E ≈ TeV). Por medio de telescopios o arreglos de detectores y utilizando la técnica mencionada, se han podido detectar algunas fuentes puntuales de mucha importancia astrofísica como la Nebulosa del Cangrejo y la galaxia de núcleo activo Markarian 421. El sistema instalado en San Juan, en cooperación con el grupo de Radiación Gamma del Observatorio Whipple, está constituído por tres colectores de 1.5m que registran pulsos de luz generados por las cascadas de partículas producidas por rayos cósmicos de todo tipo al entrar en la atmósfera terrestre. El sistema opera por barrido en ascención recta de la fuente observada que, para esta etapa del experimento, es el Centro Galáctico. Esta fuente extensa es conocida como emisor gamma de energías inferiores al TeV y ha sido observada anteriormente en este rango de energía desde el hemisferio norte pero con elevaciones bajas, situación no óptima para este tipo de técnica. Se presentan los primeros resultados del análisis de los datos obtenidos observando la región del Centro Galáctico, luego de dos años de observaciones, así como una descripción de la técnica Cherenkov Atmosférica y del equipo utilizado en la experiencia.

    Public health research and education in Mexico require further decentralization to improve its availability, quality and relevance for the development of local health systems. This article presents the experience of the Northern Regional Center for Health Systems Development (Nuredess-Norte), a consortium for the decentralization and regionalization of public health research and education of El Colegio de la Frontera Norte and the National Institute of Public Health. Nuredess-Norte initiated its activities in 1990 establishing a binational network of health systems consultants along the border, following a common methodology to improve health system quality through research. Later a Health Systems Development Teaching Program was established at the level of specialization with a high degree of decentralization and linkage with local health systems. Nuredess-Norte undertakes research, design and evaluation of innovations along the US-Mexico border. Emphasis is given to community participation and the development of primary health care.

    Host range of Xylosandrus mutilatus (Blandford) in North America is reported here for the first time. Descriptive data such as number of attacks per host, size of stems at point of attacks, and height of attacks above ground are presented. Hosts observed in Mississippi were Acer rubrum L., Acer saccharum Marsh., Acer palmatum Thunb., Ostrya virginiana (Mill.) K. Koch., Cornus florida L., Fagus grandifolia Ehrh., Liquidamber styraciflua L., Carya spp., Liriodendron tulipifera L., Melia azedarach L., Pinus taeda L., Prunus serotina Ehrh., Prunus americana Marsh., Ulmus alata Michaux, and Vitus rotundifolia Michaux. Liquidamber styraciflua had significantly more successful attacks, significantly higher probability of attacks, and significantly higher number of adult beetles per host tree than did Carya spp., A. rubrum, and L. tulipifera. This information is relevant in determining the impact this exotic beetle may have in nurseries, urban areas, and other forestry systems where this beetle becomes established.

    Varios arbovirus han emergido y/o reemergido en el Nuevo Mundo en las últimas décadas. Los virus Zika y chikungunya, anteriormente restringidos a África y quizás Asia, invadieron el continente, causando gran preocupación; además siguen ocurriendo brotes causados por el virus dengue en casi todos los países, con millones de casos por año. El virus West Nile invadió rápidamente América del Norte, y ya se han encontrado casos en América Central y del Sur. Otros arbovirus, como Mayaro y el virus de la encefalitis equina del este han aumentado su actividad y se han encontrado en nuevas regiones. Se han documentado cambios en la patogenicidad de algunos virus que conducen a enfermedades inesperadas. Una fauna diversa de mosquitos, cambios climáticos y en la vegetación, aumento de los viajes, y urbanizaciones no planificadas que generan condiciones adecuadas para la proliferación de Aedes aegypti (L.), Culex quinquefasciatus Say y otros mosquitos vectores, se han combinado para influir fuertemente en los cambios en la distribución y la incidencia de varios arbovirus. Se enfatiza la necesidad de realizar estudios exhaustivos de la fauna de mosquitos y modificaciones de las condiciones ambientales, sobre todo en las zonas urbanas fuertemente influenciadas por factores sociales, políticos y económicos. © The Authors 2017.

    Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

    Introducción: los estudiantes universitarios representan un colectivo social en riesgo desde el punto de vista nutricional, ya que a menudo mantienen estilos de vida y hábitos nutricionales inapropiados. Objetivos: analizar el estilo de vida de los alumnos del Campus de la Universidad de Granada en Melilla. Analizar la evolución de los hábitos alimentarios de los estudiantes del campus durante el curso académico 2013-2014. Material y método: se realizó un estudio longitudinal durante el curso académico 2013-2014 en el cual, a su inicio, se evaluó el estilo de vida y, de forma continuada los hábitos nutricionales de un grupo representativo de 257 estudiantes, 90 chicos (35%) y 167 chicas (65%), todos ellos del campus de la Universidad de Granada en la Ciudad Autónoma de Melilla (norte de África). Resultados: los hábitos nutricionales empeoran a medida que avanza el curso académico, caracterizándose por una reducción significativa (p < 0.001) en la ingesta de carbohidratos, así como por una elevación significativa (p < 0.001) en la ingesta proteica y lipídica, siendo especialmente rica en grasas saturadas y baja en fibra. Conclusiones: la población estudiada posee un estilo de vida eminentemente sedentario. A medida que avanza el curso académico, los hábitos nutricionales de los estudiantes empeoran, alejándose del patrón de alimentación mediterráneo con el consiguiente riesgo de desarrollar enfermedades metabólicas y cardiovasculares. De estos resultados se desprende la necesidad de continuar profundizando a fin de identificar los factores que influyen en sus hábitos nutricionales y establecer las medidas correctoras oportunas.

    Introduccion. El sindrome de apnea obstructiva del sueño (SAOS) se asocia frecuentemente a otras enfermedades que actuan como factores de riesgo que influyen en la morbilidad y mortalidad del SAOS. Objetivos. Analizar la presencia de comorbilidades en pacientes con SAOS, seleccionados en una clinica del sueño ambulatoria en el norte de Portugal y clasificados atendiendo a la gravedad del SAOS. Pacientes y metodos. Una cohorte de 319 pacientes con trastornos del sueño fueron evaluados mediante estudios clinicos y registro videopoligrafico durante el sueño. Del total de pacientes (n = 209) con distres respiratorio durante el sueño, 145 tenian SAOS con gravedad definida segun el indice de apnea/hipopnea (IAH); 64 presentaban ronquidos primarios o distres respiratorio con IAH < 5; y 110 tenian otros trastornos del sueño. Resultados. La presencia de comorbilidades fue del 75% en todos los pacientes con SAOS y del 79,5% en el grupo de pacientes con SAOS grave; 47 pacientes presentaban una unica comorbilidad, la mas comun de las cuales fue la obesidad (56,3%), seguida de hipertension, diabetes y otros trastornos cardiovasculares. La obesidad estuvo presente en el 84% de los casos mas graves de SAOS y en el 100% de casos con multiples comorbilidades. En comparacion con el grupo de pacientes con distres respiratorio durante el sueño, la comorbilidad aparece normalmente relacionada con el SAOS (p = 0,0196). Conclusion. Las comorbilidades se asocian con frecuencia al SAOS, independientemente de la gravedad de la enfermedad. Entre las comorbilidades presentes, la obesidad resulto ser la mas comun en los casos mas graves de SAOS.

    Introdução: Os profissionais de saúde foram um grupo prioritário para vacinação contra a pandemia da Gripe A (H1N1), Pandemrix®. Assim, monitorizar os eventos adversos relacionados com esta vacina neste grupo específico poderá originar informação valiosa relacionada com o perfil de segurança da vacina. O nosso objetivo foi identificar os eventos adversos após imunização com a vacina Pandemrix® em profissionais de saúde. Material e Métodos: Foi desenhado um questionário de monitorização dos eventos adversos ocorridos com a vacina Pandemrix®. O questionário foi distribuído aos profissionais de saúde a trabalhar em três centros hospitalares da região norte do País, vacinados no período de 26 de Outubro de 2009 a 31 de janeiro de 2009. Resultados: Dos 2358 profissionais de saúde que aceitaram participar no estudo, 864 (37%) devolveram o questionário preenchido. Destes, 73% experienciaram pelo menos um evento adverso após imunização, mas só 8% experienciaram um evento inesperado. Os eventos adversos mais frequentemente reportados foram os esperados e muito comuns: reações locais no local de administração (57%), mialgia (31%), fadiga (incluindo astenia) (24%) e dor de cabeça (19%). Não foram reportados casos de eventos de maior gravidade para a saúde, tais como morte ou risco de vida. O género feminino e a existência de doença de base foram fatores de risco independentes para o desenvolvimento de pelo menos um evento adverso após imunização com a Pandemrix®. Conclusões: O nosso trabalho sugere um perfil de segurança aceitável da vacina pandémica Pandermix® em profissionais de saúde. Tanto a frequência como a severidade dos eventos adversos não se verificaram superiores ao esperado.

  15. Los manuales de quimica en Espana (1788--1845): Protagonistas, terminologia, clasificaciones y orden pedagogico

    Munoz Bello, Maria Rosa

    para poder llegar a conclusiones validas. Por ello, se ha adoptado como nucleo de este trabajo la definicion de libro de texto basada en su destino y no en su funcion, es decir, los libros que de forma explicita expresan su finalidad didactica, tanto en el titulo o como en las declaraciones del autor reflejadas en el prologo de la obra, en los que ademas aparezca la palabra quimica en su titulo. El estudio comienza en 1788 con la publicacion de algunos de los primeros manuales de quimica modernos, y acaba con la reforma educativa de 1845, que tuvo importantes consecuencias en el mercado de libros de texto en Espana. Esta reforma separaba la ensenanza media de la propiamente universitaria y, de este modo, fue impulsora de la creacion de institutos provinciales de segunda ensenanza, algunos de los cuales habian comenzado su andadura en los anos anteriores. Las regulaciones introducidas suponian una fuerte limitacion para los profesores en la eleccion de los manuales de ensenanza que debian ser aprobados cada tres anos por el Consejo de Instruccion Publica. Ademas supuso una reglamentacion clara de los estudios de filosofia y su division en los estudios elementales y superiores. La investigacion se ha distribuido a lo largo de seis capitulos: Introduccion, los protagonista, el vocabulario de la quimica, poniendo orden: las clasificaciones quimicas, conclusiones y apendice. En primer lugar, se ha elaborado un repertorio bibliografico, incluido en el apendice, constituido por 76 obras de quimica publicadas en Espana desde 1788 hasta 1845 que permite realizar un analisis estadistico de su produccion. Posteriormente, se intenta conocer los principales protagonistas en la creacion del libro: editores, impresores, autores, traductores y lectores. Tradicionalmente los historiadores de la ciencia han dado mas importancia a los laboratorios y a los personajes de la investigacion cientifica, frente a las aulas y a los protagonistas de la ensenanza. La situacion ha cambiado en las

    Introdução: Os tumores primários do sistema nervoso central representam o segundo grupo de neoplasias mais frequente e são a principal causa de morte devido a tumores sólidos em crianças. O nosso estudo teve como objetivos realizar a mais atualizada análise epidemiológica desta doença no norte de Portugal e avaliar o possível benefício da centralização de cuidados. Material e Métodos: Este estudo de base populacional incluiu todos os tumores primários do sistema nervoso central diagnosticados e histologicamente confirmados em indivíduos menores de 18 anos de idade, que residem no norte do país, desde Janeiro 2008 até Dezembro 2013. Os dados foram obtidos por meio da avaliação dos processos clínicos dos doentes. Nós descrevemos as características das crianças e dos seus tumores e analisámos os quocientes doente: neurocirurgião pediátrico e tipo histológico de tumor: neurocirurgião pediátrico e as taxas de sobrevivência, mortalidade, complicações e recidiva. Resultados: Foram registados 147 casos. A média de idade ao diagnóstico foi de 8,0 ± 5,2 anos. Os astrocitomas foram o tipo histológico mais frequentemente encontrado (34%). O tipo histológico foi a única variável com influência estatisticamente significativa na mortalidade (p = 0,001). As sobrevivências a um, três e cinco anos relativas ao período entre 2008 - 2013 foram estatisticamente superiores às do intervalo entre 2005 - 2007. Os astrocitomas apresentam a mais alta taxa de sobrevivência, sendo estatisticamente diferente dos outros tipos de tumor (p = 0,015). Estimámos uma média de 12,25 casos tratados anualmente por neurocirurgião pediátrico no nosso hospital. Discussão: Os nossos resultados são, globalmente, consistentes com os encontrados na literatura mundial, mas registrámos taxas de sobrevivência mais altas. O número de casos tratados por neurocirurgião pediátrico está de acordo com o recomendado. Conclusão: Demonstrámos que houve melhoria

    The use of multiport mini-channel tubes in compact exchangers has increased in the last few years. They contributing to improve thermal efficient, compactness, energy conservation and required lower refrigerants charge by which reduction of greenhouse gases emission. Those mentioned advantages are very important aspects with regard to modern refrigeration systems design. For that reason, several experimental investigation have been carried out in order to characterize the flow boiling heat transfer process and frictional pressure drop in tubes with parallel channels. Since, the ability to estimate pressure drop and heat transfer coefficient for specific conditions is a fundamental issue to optimise the design of compact heat exchanger. In this study, the characteristics of two- phase flow pressure drop and convective boiling heat transfer have been investigated experimentally inside multiport mini-channel aluminium tube with triangular geometry, hydraulic diameter 0.715 mm and heating length of 1205 mm using R32 and R134a as working fluids. A wide experimental campaign has been carried out to complete an array of measurement under different conditions for both refrigerants studied. The experimental conditions examined included: mass velocity 275-1230 kgm -2s-1, heat flux 0.75-9.30 kWm-2, saturation temperature, 5°C, 7.5°C, 12.5°C, vapour quality 0.012-0.51. The database presented consists of 312 averages values, 223 averages values were recorded for R134a and 89 for R32. The flow boiling averages values were calculated selecting a sample of 40 readings (steps 20s) in stable conditions for all measured variables at each mass velocity tested.

    the aim of this study was to conduct an in vitro comparison of marginal microleakage (MM) and the depth of penetration (DP) of glass ionomer cements (GIC) and a resin sealant (RS) into occlusal pit and fissures. for that purpose, 60 intact third molars were equally distributed to 5 groups: G1 - 37% phosphoric acid / Delton; G2 - 40% polyacrylic acid / Ketac-Molar / nail varnish; G3 - Fuji Plus conditioner / Fuji Plus/ nail varnish; G4 -37% phosphoric acid / Vitremer / Finishing gloss; G5 -37% phosphoric acid / Vitremer prepared with a 1:4 ratio of powder / Finishing gloss. The teeth were submitted to a thermal treatment corresponding to 300 cycles (15 sec, 5/55(0)C), followed by complete coating with nail varnish, except for 1mm beyond the contour of the sealant. Afterwards, the teeth were immersed in 0.5% basic fuchsine for 24 hours. Thereafter, the teeth were sectioned in buccolingual direction and microscopically analyzed (150x magnification) by means of predetermined scores. The results were subject to the Kruskal-Wallis test. there was no statistical difference between the materials tested in relation to the DP, being that all groups displayed nearly complete filling of the fissures. No sealant material was able to prevent dye penetration; however, the GICs provided better results of MM, with significant difference when compared to the RS. all materials investigated presented a satisfactory degree of penetration into the fissures; however, the glass ionomer cements displayed better performance in the marginal microleakage test compared to the resin sealant.

    Introdução: A encefalopatia hepática mínima define-se como um défice neurocognitivo ligeiro, não detectável ao exame clínico, que pode estar presente nos doentes cirróticos. Objectivo: Determinar a prevalência da encefalopatia hepática mínima num hospital prestador de cuidados de saúde secundários no Norte de Portugal. Material e Métodos: Realizou-se um estudo transversal em que foram incluídos os doentes cirróticos seguidos na consulta externa. Critérios de exclusão: encefalopatia hepática clínica, iliteracia, consumo activo de álcool e terapêutica com fármacos psicotrópicos ou lactulose. A presença de encefalopatia hepática mínima foi definida como um valor ≥ -4 na Pontuação Psicométrica da Encefalopatia Hepática, calculado de acordo com as normas portuguesas. Analisaram-se as variáveis: etiologia e gravidade da doença hepática e concentração da amónia sanguínea venosa. Considerou-se o valor de p < 0,05 como significativo. Resultados: Dos 102 doentes avaliados, 41 foram incluídos: 31 homens, idade média de 57 ± 10 anos, escolaridade média de 5 ± 2 anos, 31 Child-Pugh classe A, score MELD médio de 6 ± 3. Foi diagnosticada encefalopatia hepática mínima em 14 (34%) doentes. A presença de encefalopatia hepática mínima não se relacionou com a gravidade da doença hepática. Apesar de mais elevado, o valor médio da concentração da amónia venosa nos doentes com encefalopatia hepática mínima não foi significativamente diferente do valor médio da concentração da amónia venosa nos doentes sem encefalopatia hepática mínima (48,5 ± 13,3 vs. 45,6 ± 15,6 μmol/L, p = 0,555). Discussão: A prevalência da encefalopatia hepática mínima descrita está de acordo com os dados internacionais. Conclusão: A encefalopatia hepática mínima é uma entidade frequente que está presente precocemente na história natural da cirrose, mesmo em doentes compensados. Consequentemente, esta condição escondida deve ser

    Introducción: Los estilos de vida actuales han provocado un aumento de las actividades sedentarias y una disminución de la actividad física, lo que puede conllevar un empeoramiento de la salud presente y futura de la población infantil. Objetivos: El objetivo del estudio fue describir los hábitos de vida y actividad física de una población de escolares de una ciudad del norte de España, así como analizar las relaciones entre dichos hábitos y la composición corporal, la condición física y algunos factores sociodemográficos. Métodos: El estudio se llevó a cabo sobre una muestra representativa de 329 escolares de sexto de primaria (11-12 años) de las 31 escuelas de Logroño (La Rioja). Se registraron datos sociodemográficos, antropométricos, tensión arterial, desarrollo madurativo, condición física y hábitos de vida y de actividad física. Resultados: Los alumnos de género masculino, quienes practicaban actividades deportivas extraescolares y los que se encontraban en un estadio de desarrollo menor reportaron mayores niveles de actividad física. Se encontraron correlaciones directas entre la práctica y la condición física, especialmente con la capacidad aeróbica (r=0,38), e inversas con las horas frente a la pantalla (r=- 0,18), pero no con la composición corporal. Conclusiones: Dadas las relaciones entre los niveles de actividad y la condición física, estrategias de promoción de la práctica física deberían fomentarse con el fin de mejorar la salud de los jóvenes. Las intervenciones deberían centrarse en favorecer el acceso a las actividades deportivas extraescolares, reducir los hábitos sedentarios y aumentar el nivel de práctica física del género femenino.

    Introdução: A resistência aos antimicrobianos, provocada pela utilização de antibióticos continua a ser um importante problema de saúde pública e uma preocupação para os profissionais de saúde. O nosso objetivo foi conhecer a prevalência local dos uropatógenos e o seu perfil de suscetibilidade aos antimicrobiannos na pielonefrite aguda. Material e Métodos: Estudo prospetivo nas crianças internadas por pielonefrite aguda no internamento de Pediatria de um hospital do norte de Portugal entre 1994-2012. Os agentes etiológicos e o seu perfil de sensibilidade aos antimicrobianos foram avaliados em quatro períodos de tempo (G1: 1994-1997, G2: 2002; G3: 2007; G4: 2012). Resultados: Avaliámos 581 doentes, 66% do sexo feminino, com idade mediana de 22 meses. A Escherichia coli foi o principal uropatógeno e a sua prevalência manteve-se estável durante os últimos 18 anos. Verificou-se um aumento da sensibilidade à amoxicilina/ácido clavulânico de 71% no G1 para 81,5% no G4 (p = 0,001) e uma diminuição da taxa de resistência de 8,7% no G1 para 2,8% G4 (p = 0,008). A sua sensibilidade às cefalosporinas de segunda e terceira geração e nitrofurantoína foi superior a 90% (p = ns). A taxa de resistência ao cotrimoxazol aumentou de 22 % para 26 % (p = 0,008). Discussão: A Escherichia coli continua a ser o uropatogénio mais frequente responsável por pielonefrite aguda, motivo pelo qual o seu perfil de sensibilidade aos antimicrobianos determina a escolha da antibioticoterapia empírica. Conclusões: A amoxicilina/ácido clavulânico mantém-se como escolha de primeira linha para o tratamento empírico da pielonefrite aguda em regime de internamento.

    2017-01-12

    Control of atherosclerotic cardiovascular disease - a highly prevalent condition and one of the main causes of mortality in Brazil and worldwide - is a recurrent subject of great interest for public health. Recently, three new guidelines on dyslipidemia and atherosclerosis prevention have been published. The close release of these important publications is a good opportunity for comparison: the Brazilian model has greater sensitivity, the English model does not work with risk stratification, and the American model may be overestimating the risk. This will allow reflection on current progress and identification of controversial aspects which still require further research and debate. It is also an opportunity to discuss issues related to early diagnosis and its efficiency as a preventive strategy for atherosclerotic disease: the transformation of risk into disease, the gradual reduction of cut-off points, the limitations of the screening strategy, and the problem of overdiagnosis. RESUMO O controle da doença cardiovascular aterosclerótica - morbidade de alta prevalência e uma das principais causas de mortalidade no Brasil e no mundo - continua sendo tema de grande interesse para a Saúde Pública. Recentemente, três novas diretrizes sobre dislipidemia e prevenção da aterosclerose foram divulgadas. A convergência no tempo dessas importantes publicações constitui boa oportunidade para sua comparação: o modelo brasileiro tem maior sensibilidade, o inglês não trabalha com risco estratificado e o norte-americano parece estar superestimando o risco.Isso permitirá reflexões acerca dos avanços que já foram alcançados e identificação de aspectos ainda controversos, que seguem exigindo novas pesquisas e debates.

    Spawning aggregations of red hind Epinephelus guttatus, tiger grouper Mycteroperca tigris and yellowfin grouper Mycteroperca venenosa were identified at two coral-reef systems: Arrecife Alacranes (emergent bank reef) and Bajos del Norte (submerged bank reef) on the continental shelf of the Yucatan Peninsula (Campeche Bank), Mexico. At both reefs, E. guttatus forms large spawning aggregations between February and March. At Bajos del Norte, M. tigris reproduces in a small, low-density aggregation in May, while M. venenosa aggregates at high densities for spawning between March and May. Multi-species use of an aggregation site by E. guttatus and M. venenosa was observed at Bajos del Norte. The identified spawning aggregations are apparently stable in location over time, and all three species were commonly observed to spawn within 1 week following the full moon. Development and survival of the larvae spawned in these aggregations are probably aided by a seasonal (spring-summer) upwelling in the north-east Campeche Bank. A permanent area closure at Bajos del Norte, currently outside any specific fisheries management area or regulations, would provide protection needed for the spawning aggregations of these three species. © 2014 The Fisheries Society of the British Isles.
