    2011-01-01

    Endotoxins, i.e. components originating from the outer membrane in the cell wall of Gram-negative bacteria, activate the human immune system, which may result in airway symptoms such as shortness of breath and airway inflammation. Endotoxins are present in the environment, both outdoors and indoors, and stay airborne for a long time. In order to investigate the levels of endotoxins in urban air and the influence of traffic and meteorological factors, particles (PM 10 and PM 2.5) were collected at five sites in Stockholm, Sweden on four occasions per site between May and September 2009. Endotoxins were extracted from the filters and analysis was conducted with the Limulus Amebocyte Lysate (LAL)-assay. Endotoxins were present in urban air in Stockholm, albeit in low levels, and were similar to levels found in urban areas outside Sweden. To our knowledge, this is the northernmost location where endotoxins have been measured. The endotoxin levels found in PM 10 ranged from 0.020 to 0.107 EU m -3 with a geometric mean of 0.050 EU m -3 and the levels found in PM 2.5 ranged from 0.005 to 0.064 EU m -3 with a geometric mean of 0.015 EU m -3. No obvious effects of traffic or meteorological factors on endotoxin levels were observed, although a moderate correlation could be seen with soot. The small number of sampling sites is however a shortcoming of the present study. In future studies, more sites and sampling during all seasons would be preferable in order to get a better picture of the influence of different sources on endotoxin levels.

    Background: The mortality impacts of hot and cold temperatures have been thoroughly documented, with most locations reporting a U-shaped relationship with a minimum mortality temperature (MMT) at which mortality is lowest. How MMT may have evolved over previous decades as the global mean surface temperature has increased has not been thoroughly explored. Objective: We used observations of daily mean temperatures to investigate whether MMT changed in Stockholm, Sweden, from the beginning of the 20th century until 2009. Methods: Daily mortality and temperature data for the period 1901–2009 in Stockholm, Sweden, were used to model the temperature–mortality relationship. We estimated MMT using distributed lag nonlinear Poisson regression models considering lags up to 21 days of daily mean temperature as the exposure variable. To avoid large influences on the MMT from intra- and interannual climatic variability, we estimated MMT based on 30-year periods. Furthermore, we investigated whether there were trends in the absolute value of the MMT and in the relative value of the MMT (the corresponding percentile of the same-day temperature distribution) over the study period. Results: Our findings suggest that both the absolute MMT and the relative MMT increased in Stockholm, Sweden, over the course of the 20th century. Conclusions: The increase in the MMT over the course of the 20th century suggests autonomous adaptation within the context of the large epidemiological, demographical, and societal changes that occurred. Whether the rate of increase will be sustained with climate change is an open question. Citation: Oudin Åström D, Tornevi A, Ebi KL, Rocklöv J, Forsberg B. 2016.

    2004-01-01

    Background: Most epidemiological studies on adverse health effects among women in relation to occupational magnetic field exposure have been based on information about men's exposure. Aims: To create a job-exposure matrix for occupational exposure to extremely low frequency magnetic fields among women. Methods and Results: Measurements were performed using personal magnetic field meters (Emdex Lite) carried by the subjects for 24 hours on a normal workday. Subjects were volunteer women working in the occupations identified as common among women in Stockholm County based on the 1980 census. A total of 471 measurements were made in 49 different occupations, with a minimum of 5 and a maximum of 24 measurements in each occupation. The included occupations cover about 85% of the female population gainfully employed in 1980. Parameters representing average and peak magnetic field exposures, temporal change in the exposure, and proportion of time spent above certain exposure levels were calculated both for the workday and for the total 24 hour period grouped by occupational titles. The occupations with higher than average exposure were cashiers, working proprietors in retail trade, air stewardesses, dental nurses, cooks, post-office clerks and kitchen maids. Conclusions: This new job-exposure matrix substantially increases the knowledge about magnetic field exposure among women and can be used for exposure assessment in future studies. PMID:15208375

    The recycling behaviour of multicultural householders was investigated in the urban area of Järva, northwest Stockholm, Sweden, which is home to a significant proportion of immigrants from different parts of the world. Different ethnic minorities currently make up an important proportion of the urban population in Sweden, but little is known about their recycling behaviour and attitudes. Using quantitative (questionnaire) and qualitative (interviews) methodology, possible determinants of recycling behaviour were investigated among Järva householders. It was found that attitude toward the importance of recycling had a positive correlation and was the main determinant of recycling behaviour among these householders. In contrast, environmental concern, satisfaction with the facilities provided, recycling confidence, community identity and socio-demographical factors showed no correlation with their recycling behaviour. Other results of the study indicated a need to investigate the specific behaviour of multicultural householders regarding source-separated collection and the recycling of hazardous, electronic and bulky wastes.

    Today, concerns prevail about the unsustainable use of phosphorus and worldwide eutrophication, thus requiring efficient management of phosphorus flows. With increasing population and associated urban growth, urban management of phosphorus flows in the perspectives of recycling, eutrophication and total budget becomes increasingly important. This study mapped phosphorus flows for a reference year (2013) and a future year (2030) using different scenarios for the city of Stockholm, Sweden. The results indicated that the Swedish goal of recycling phosphorus from wastewater would cover the majority of the total phosphorus budget for Stockholm. However, in 2013, only 10% of phosphorus was recycled for agricultural use, around half of which was from sewage sludge and the other half from food waste. Almost 50% of total phosphorus was sent to landfill/mining waste capping with sewage sludge, for economic reasons and lack of market. Among the scenarios of upstream and downstream urban management options studied in combination with population growth, recovery of phosphorus from sewage sludge had the greatest potential to increase the fraction recycled to agriculture. However, only upstream measures, e.g. changed diet, were able to reduce the total phosphorus budget. Urban management of phosphorus flows based on the different perspectives of recycling, eutrophication or total budget was shown to potentially result in different preferred management actions and both upstream and downstream measures need to be considered. Moreover, management needs to pay attention to small but environmentally sensitive flows, particularly when setting city goals on phosphorus recycling by percentage in a large budget. PMID:26442719

    The 8th International Conference on Alzheimer's Disease and Related Disorders, held in Stockholm, Sweden from July 20 to 25, 2002, provided an exciting forum for nearly 3700 researchers from 78 countries to present and discuss advances in dementia research on a worldwide stage. Hosted by the Alzheimer's Association (Chicago, IL), this largest dementia research conference ever held united experienced researchers and relative newcomers to the field to learn from one another, challenge one another's thinking, and explore new possibilities for collaboration. The 12-fold growth in attendance, up from 300 scientists at the 1st International Research Conference in 1988, signals the increasing global importance of Alzheimer's disease in the research community as well as among policy makers and the general public. In fact, a recent survey of older Americans by the National Council on the Aging revealed that future memory loss was the number one health worry of the American elderly population.

    2015-07-01

    This population-based register study explored the association between having a child with/without autism spectrum disorder (ASD) and parental sick leave and work participation. Parents of children with ASD living in Stockholm, Sweden in 2006 were more likely to be on sick leave, not in the labor force, or earning low income when compared to parents who did not have a child with ASD and these results remained after adjusting for familial socioeconomic factors and parental psychiatric care. Sick leave among parents was associated with having a child with ASD without intellectual disability (ID) but not ASD with ID. Although Sweden has policies helping families with children with ASD this study suggests that there exist unmet needs among these parents. PMID:25697737

    2011-01-01

    Background: Although serious health effects associated with particulate matter (PM) with aerodynamic diameter ≤ 10 μm (PM10) and ≤ 2.5 μm (PM2.5; fine fraction) are documented in many studies, the effects of coarse PM (PM2.5–10) are still under debate. Objective: In this study, we estimated the effects of short-term exposure of PM2.5–10 on daily mortality in Stockholm, Sweden. Method: We collected data on daily mortality for the years 2000 through 2008. Concentrations of PM10, PM2.5, ozone, and carbon monoxide were measured simultaneously in central Stockholm. We used additive Poisson regression models to examine the association between daily mortality and PM2.5–10 on the day of death and the day before. Effect estimates were adjusted for other pollutants (two-pollutant models) during different seasons. Results: We estimated a 1.68% increase [95% confidence interval (CI): 0.20%, 3.15%] in daily mortality per 10-μg/m3 increase in PM2.5–10 (single-pollutant model). The association with PM2.5–10 was stronger for November through May, when road dust is most important (1.69% increase; 95% CI: 0.21%, 3.17%), compared with the rest of the year (1.31% increase; 95% CI: –2.08%, 4.70%), although the difference was not statistically significant. When adjusted for other pollutants, particularly PM2.5, the effect estimates per 10 μg/m3 for PM2.5–10 decreased slightly but were still higher than corresponding effect estimates for PM2.5. Conclusions: Our analysis shows an increase in daily mortality associated with elevated urban background levels of PM2.5–10. Regulation of PM2.5–10 should be considered, along with actions to specifically reduce PM2.5–10 emissions, especially road dust suspension, in cities. PMID:22182596

  12. Nutrient loadings from urban catchments under climate change scenarios: case studies in Stockholm, Sweden.

    Anthropogenic nutrient emissions and associated eutrophication of urban lakes are a global problem. Future changes in temperature and precipitation may influence nutrient loadings in lake catchments. A coupling method, where the Generalized Watershed Loading Functions method was tested in combination with source quantification in a Substance Flow Analysis structure, was suggested to investigate diffuse nutrient sources and pathways and climate change effects on the loadings to streamflow in urban catchments. This method may, with an acceptable level of uncertainty, be applied to urban catchments for first-hand estimations of nutrient loadings in the projected future and to highlight the need for further study and monitoring. Five lake catchments in Stockholm, Sweden (Råcksta Träsk, Judarn, Trekanten, Långsjön and Laduviken) were employed as case studies and potential climate change effects were explored by comparing loading scenarios in two periods (2000-2009 and 2021-2030). For the selected cases, the dominant diffuse sources of nutrients to urban streamflow were found to be background atmospheric concentration and vehicular traffic. The major pathways of the nitrogen loading were suggested to be from both developed areas and natural areas in the control period, while phosphorus was indicated to be largely transported through surface runoff from natural areas. Furthermore, for nitrogen, a modest redistribution of loadings from surface runoff and stormwater between seasons and an increase in the annual loading were suggested for the projected future climate scenarios as compared to the control period. The model was, due to poor monitoring data availability, only able to set an upper limit to nutrient transport by groundwater both in the control period and the future scenarios. However, for nitrogen, groundwater appeared to be the pathway most sensitive to climate change, with a considerable increase and seasonal redistribution of loadings. For phosphorus

    Resource productivity and evidence of economic decoupling were investigated on the basis of the time series in 1996-2011 of material flow analysis for Sweden, Stockholm, and Gothenburg. In the three cases, absolute reductions in CO2 emissions by about 20% were observed, energy consumption per capita decreased, while gross domestic product (GDP) per capita grew. The energy consumption of the residential and public sectors decreased drastically, while the transport energy consumption is still growing steadily. Decoupling of the economy as a whole (i.e., including materials) is not yet happening at any scale. The domestic material consumption (DMC) continues to increase, in parallel with the GDP. The rate of increase for DMC is slower than that for GDP in both Stockholm and Sweden as a whole (i.e., relative decoupling). The metabolism of the cities does not replicate the national metabolism, and the two cities each have their own distinct metabolism profiles. As a consequence, policy implications for each of the case studies were suggested. In general, because of the necessarily different roles of the two cities in the national economy, generic resource productivity benchmarks, such as CO2 per capita, should be avoided in favor of sectorial benchmarks, such as industry, transport, or residential CO2 per capita. In addition, the share of the city impacts caused by the provision of a service for the rest of the country, such as a port, could be allocated to the national economy.

    Mass flows of 13 pharmaceutical active ingredients (APIS) found in drinking water were studied in the water cycle of Stockholm. Data were collected by analyzing samples of surface water, raw water and drinking water as well as influents, effluents and sludges from waste water treatment plants (WWTPs) in Stockholm area. A mass balance was performed, based on sold amounts of pharmaceuticals and the measured concentrations in water and sludge. The selected APls were all present in WWTP effluents and the removal rates for many of them were poor. Mass balance calculations showed that the three studied WWTPs in Stockholm release considerable amounts of the selected APIs into the Baltic Sea while the portions ending up in WWTP sludge were significantly lower. The levels of APIs found in drinking water are low at present, but may increase in the future unless the releases from WWTPs in the catchment of Lake Mälären are mitigated.

    This study addresses social-ecological dynamics in the greater metropolitan area of Stockholm County, Sweden, with special focus on the National Urban Park (NUP). It is part of the Millennium Ecosystem Assessment (MA) and has the following specific objectives: (1) to provide scientific information on biodiversity patterns, ecosystem dynamics, and ecosystem services generated; (2) to map interplay between actors and institutions involved in management of ecosystem services; and (3) to identify strategies for strengthening social-ecological resilience. The green areas in Stockholm County deliver numerous ecosystem services, for example, air filtration, regulation of microclimate, noise reduction, surface water drainage, recreational and cultural values, nutrient retention, and pollination and seed dispersal. Recreation is among the most important services and NUP, for example, has more than 15 million visitors per year. More than 65 organizations representing 175,000 members are involved in management of ecosystem services. However, because of population increase and urban growth during the last three decades, the region displays a quite dramatic loss of green areas and biodiversity. An important future focus is how management may reduce increasing isolation of urban green areas and enhance connectivity. Comanagement should be considered where locally managed green space may function as buffer zones and for management of weak links that connect larger green areas; for example, there are three such areas around NUP identified. Preliminary results indicate that areas of informal management represent centers on which to base adaptive comanagement, with the potential to strengthen biodiversity management and resilience in the landscape.

    The objective of this study is to understand the spatial and temporal dynamics of suicides in commuting railway environments. Data on suicides in Stockholm commuting railway from 2006 to 2013 was analysed. The study sets out to identify significant clusters in suicides then evaluate whether commuting railway environments affect variations in suicide rates. Fieldwork inspection, spatial cluster techniques (NNHC and Getis-Ord statistics) and regression models underlie the methodology of study. Findings show no seasonality was observed in suicide cases, but winter months concentrate a larger share of events. Suicides do not occur evenly throughout the day but tend to take place more often in weekdays. Modelling findings shows that suicide rates increase with speed trains and decrease where barriers along tracks are installed. Although high speed trains are still a motive of concern for suicide prevention, findings call for a whole railway-approach to safety - one that extends maintenance beyond the platforms and stations' vicinities.

  20. Exact results in gauge-string dualities (Stockholm, Sweden, 23 January-17 February 2012)

    Zarembo, Konstantin

    2012-08-01

    Exactly solvable models play a distinguished role in physics, as they help us understand the behavior of strongly correlated, strongly coupled systems in the regimes where other methods fail. For a long time, the exact solvability was associated with (1+1)-dimensional systems, where powerful methods of integrability allow one to find the exact spectrum, to study thermodynamics and to compute correlation functions for a number of strongly interacting field theories. The AdS/CFT duality established a rigorous relationship between gauge fields and strings, and paved the way for applying the methods of integrability in four-dimensional gauge theories. The two-dimensional dynamics on the string worldsheet (dual to the fluctuating electric flux tube in a gauge theory) is in many cases integrable, which opens the avenue for applications of non-perturbative, integrability-based methods to four-dimensional gauge theories. The progress in understanding non-perturbative phenomena in gauge theories has been rapid in recent years, and required synergy of methods from exactly solvable models, gauge theories, strings and integrable systems. The program 'Exact Results in Gauge-String Dualities' took place at Nordita, Stockholm from 23 January to 17 February 2012 and brought together specialists with common interests in string theory, quantum field theory and exactly solvable models. Topics discussed during the program included: (i) exact results in the AdS/CFT correspondence, (ii) scattering amplitudes, (iii) supersymmetric gauge theories, and (iv) Bethe ansatz and exact solvability in quantum field theory and statistical systems. The articles by D Sorokin [1] and M de Leeuw et al [2] give an overview of the string-theory origins of integrability in gauge theories, and of the algebraic structures omnipresent in quantum integrable systems. The topics covered in these articles underpin the integrability approach to gauge--string dualities and lie at the heart of the integrability

    Background For the past two decades, several studies have reported associations between elevated levels of ambient air pollution and adverse pregnancy outcomes, although with varying conclusions. Objectives To examine possible associations between the traffic pollution situation at the home address, for women who did not change address during pregnancy, and three types of pregnancy outcomes: spontaneous preterm delivery, children born small for gestational age (SGA) and pregnancy-induced hypertensive disorders. Methods We used data for the Greater Stockholm Area from the Swedish Medical Birth Register to construct a cohort based on all pregnancies conceived between July 1997 and March 2006, n=100 190. The pregnancy average nitrogen oxide, NOx, levels and annual mean daily vehicles at the home address were used as exposure variables. Mixed-model logistic regression was performed to assess any associations between exposure and outcome. Results There was an association between elevated traffic pollution exposure during pregnancy and pregnancy-induced hypertensive disorders. A 10 µg/m3 increase in the pregnancy average NOx level at the home address resulted in an OR of 1.17 (95% CI 1.10 to 1.26). The 2nd to 4th quartiles of NOx were all associated with an increased risk of SGA, but there was no difference in the risk estimate among the higher quartiles. There was a tendency of a higher risk of spontaneous preterm delivery in relation to higher levels of NOx. There was no evidence of an association between vehicle flow, the cruder indicator of traffic pollution, and the studied outcomes in this study. Conclusions In this large cohort, there was a fairly strong association between vehicle exhaust levels at the home address and pregnancy-induced hypertensive disorders, after adjustment for important risk factors.

    Background Widespread testing and screening for genital Chlamydia trachomatis is often advocated as an important method to halt the epidemic. Sweden has long tradition of opportunistic screening services. Nevertheless infections rates have continued to rise over the past two decades, despite increased access to testing and treatment services. Methods In this retrospective cohort study we describe the testing behavior for genital Chlamydia trachomatis among youth in Stockholm County, with a focus on repeated testing. Specifically we (a) study positivity rates among single and repeat testers, we (b) estimate the incidence of repeat testing and the rates of infection in repeat testing episodes, and we (c) estimate time to repeat testing and factors associated with repeat testing. All youth (aged ≥12 and <26) that tested for Chlamydia trachomatis in one of 33 Youth Health Clinics in Stockholm County between 1 January 2010 and 31 December 2012 were included in the study. Results The cohort comprised a total of 65,951 individuals who did 119,699 tests during the study period. 42% of youth were repeat testers, the incidence of repeat testing was 35.0/100 person years. The overall baseline prevalence was 7.9%. Positivity rates of baseline tests among repeat testers were nearly twice as high among single testers of either sex. These were 17.1% and 9.8% among male repeat and single testers respectively. The corresponding rates for women were 9.4% and 4.3%. Positivity rates among repeat tests did not decline compared to the overall baseline positivity. Baseline test result and sex significantly influenced the occurrence of repeat testing. Conclusion Among repeat testers we found high rates of Chlamydia trachomatis both at baseline and at repeat tests which suggests the possibility that this group might be continuing to engage in unsafe sexual practices. Given the extent of repeat testing and the high positivity rates on repeat testing, further research among this group is

    The Stockholm Central Railway Station in Sweden was investigated for public radiofrequency (RF) radiation exposure. The exposimeter EME Spy 200 was used to collect the RF exposure data across the railway station. The exposimeter covers 20 different radiofrequency bands from 88 to 5,850 MHz. In total 1,669 data points were recorded. The median value for total exposure was 921 μW/m2 (or 0.092 μW/cm2; 1 μW/m2=0.0001 μW/cm2) with some outliers over 95,544 μW/m2 (6 V/m, upper detection limit). The mean total RF radiation level varied between 2,817 to 4,891 μW/m2 for each walking round. High mean measurements were obtained for GSM + UMTS 900 downlink varying between 1,165 and 2,075 μW/m2. High levels were also obtained for UMTS 2100 downlink; 442 to 1,632 μW/m2. Also LTE 800 downlink, GSM 1800 downlink, and LTE 2600 downlink were in the higher range of measurements. Hot spots were identified, for example close to a wall mounted base station yielding over 95,544 μW/m2 and thus exceeding the exposimeter's detection limit. Almost all of the total measured levels were above the precautionary target level of 3–6 μW/m2 as proposed by the BioInitiative Working Group in 2012. That target level was one-tenth of the scientific benchmark providing a safety margin either for children, or chronic exposure conditions. We compare the levels of RF radiation exposures identified in the present study to published scientific results reporting adverse biological effects and health harm at levels equivalent to, or below those measured in this Stockholm Central Railway Station project. It should be noted that these RF radiation levels give transient exposure, since people are generally passing through the areas tested, except for subsets of people who are there for hours each day of work.

    Epidemiology studies of health effects from air pollution, as well as impact assessments, typically rely on ambient monitoring data or modelled residential levels. The relationship between these and personal exposure is not clear. To investigate personal exposure to NO2 and its relationship with other exposure metrics and time-activity patterns in a randomly selected sample of healthy working adults (20–59 years) living and working in Stockholm. Personal exposure to NO2 was measured with diffusive samplers in sample of 247 individuals. The 7-day average personal exposure was 14.3 µg/m3 and 12.5 µg/m3 for the study population and the inhabitants of Stockholm County, respectively. The personal exposure was significantly lower than the urban background level (20.3 µg/m3). In the univariate analyses the most influential determinants of individual exposure were long-term high-resolution dispersion-modelled levels of NO2 outdoors at home and work, and concurrent NO2 levels measured at a rural location, difference between those measured at an urban background and rural location and difference between those measured in busy street and at an urban background location, explaining 20, 16, 1, 2 and 4% (R2) of the 7-day personal NO2 variation, respectively. A regression model including these variables explained 38% of the variation in personal NO2 exposure. We found a small improvement by adding time-activity variables to the latter model (R2 = 0.44). The results adds credibility primarily to long-term epidemiology studies that utilise long-term indices of NO2 exposure at home or work, but also indicates that such studies may still suffer from exposure misclassification and dilution of any true effects. In contrast, urban background levels of NO2 are poorly related to individual exposure. PMID:22745780

    The number of studies analysing income inequality and health are voluminous. However, when empirically testing the income inequality hypothesis, the level of aggregation could be crucial for whether we find an association or not and for the mechanisms we believe are active. This study hence investigates: (1) the two-year lagged effect by income inequality on health at two levels of aggregation; municipalities and neighbourhoods in Sweden; (2) whether spending on social goods accounts for the association between income inequality and health; (3) the effect by income inequality among the affluent and the disadvantaged in municipalities and neighbourhoods, respectively. The empirical data is based on a Swedish public health survey in 2002 and includes residents of Stockholm aged 18-84 years. The sample consists of 28,092 individuals nested within 22 municipalities and 709 neighbourhoods in the county of Stockholm with a non-response rate of 37 percent. A total population register (HSIA) is further used for the construction of contextual-level indicators. Primary method used is multi-level logistic regression. The findings indicate a moderate effect by high and very high income inequality on self-rated poor health at the municipality-level. The association, however, ceases after adjustment for spending on social goods. No detrimental effect by income inequality on self-rated health at the neighbourhood-level is found. The results further suggest that poor individuals residing in high inequality neighbourhoods do not have poorer health than those residing in low inequality contexts while high inequality is most deleterious for poor individuals at the municipality-level. In sum, the findings suggest that reduced spending on social goods could account for the association between income inequality and health at the municipality-level. The contrasting findings at the neighbourhood- and municipality-level indicate that it is important to consider the level of aggregation

  6. Factors affecting non-tailpipe aerosol particle emissions from paved roads: On-road measurements in Stockholm, Sweden

    Hussein, Tareq; Johansson, Christer; Karlsson, Hans; Hansson, Hans-Christen

    A large fraction of urban PM 10 concentrations is due to non-exhaust traffic emissions. In this paper, a mobile measurement system has been used to quantify the relative importance of road particle emission and suspension of accumulated dust versus direct pavement wear, tire type (studded, friction, and summer), pavement type, and vehicle speed. Measurements were performed during May-September on selected roads with different pavements and traffic conditions in the Stockholm region. The highest particle mass concentrations were always observed behind the studded tire and the lowest were behind the summer tire; studded-to-summer ratios were 4.4-17.3 and studded-to-friction ratios were 2.0-6.4. This indicates that studded tires lead to higher emissions than friction and summer tires regardless to the asphalt type. By comparing with measurements in a road simulator, it could be estimated that the pavement wear due to the friction tires was 0.018-0.068 of the suspension of accumulated road dust. Likewise for studded tires road-wear was estimated to be 1.2-4.8 the suspension of accumulated dust. This indicates that wear due to friction tires is very small compared to the suspension of accumulated dust and that suspension due to studded tires may sometimes be as large as the wear of the road. But this will vary depending on, e.g. the amount of dust accumulated on the roads. An important dependence on vehicle speed was also observed. During May, the particle mass concentrations behind the studded tire at vehicle speed 100 km h -1 were about 10 times higher than that at 20 km h -1. The speed dependence was not so pronounced in September, which could be due to less accumulated dust on the roads. The particle number size distribution of the emissions due to road wear by studded tire was characterized by a clear increase in number concentrations of the coarse fraction of aerosol particles, with a geometric mean diameter between 3 and 5 μm. The size distribution of the

    After a large forest fire in Tyresta National Park, Sweden, monitoring programs were started to study the consequences on the biology and chemistry in the burned area. To study the effects on the water chemistry, four brooks in the same water system were chosen for further studies. Samples were also taken in a limed lake downstream the brooks. The sites were sampled 10 times each year, starting the month after the fire, and a range of chemical analyses where performed. Pre-fire data exists for 2 of the brooks and the lake due to former studies in the area. In the brooks drastic changes of the water chemistry were seen immediately after the fire. pH in the brooks deereased with up to 2 pH-units from over 6 to about 4,5 and labile inorganic aluminium increased to over 400 μg/l in the most affected brooks. Other determined metals and nutrients in the brooks also increased. In the lake no changes in pH or aluminium were measured, but significant (p<0,01) increases of chloride, sulphate, magnesium, potassium, sodium, manganese, zinc and cadmium where observed. The water chemical effects may be explained by release of e.g. hydrogen- and aluminium ions through burning of organic matter in the acidified soil, but also by the large amounts of brackish water used during the fire-fighting operations. The extent of the effects from the fire are yet to be seen, as the concentrations of many water chemical variables still are increased three years after the fire.

  9. The "Clubs against Drugs" program in Stockholm, Sweden: two cross-sectional surveys examining drug use among staff at licensed premises

    PubMed Central

    2011-01-01

    Background The objective of this study is to examine self-reported drug use among staff at licensed premises, types of drugs used, attitudes towards drugs, and observed drug use among guests. Results are presented from two measurement points (in 2001 and 2007/08). This study was carried out within the framework of the "Clubs against Drugs" program, which is a community-based multi-component intervention targeting licensed premises in Stockholm, Sweden. Methods Two cross-sectional surveys were conducted, the first in 2001 and the second in 2007/08. Staff at licensed premises attending server training were asked to participate in the anonymous survey. A survey was administered in a classroom setting and consisted of four sections: 1) demographics, 2) respondents' own drug use experience, 3) respondents' attitudes towards drug use, and 4) observed drug use among guests at licensed premises. Results Data were collected from 446 staff in 2001 and 677 staff in 2007/08. The four most commonly used drugs among staff were cannabis, cocaine, amphetamine, and ecstasy. The highest rates of drug use were reported by staff in the two youngest age groups, i.e., those younger than 25 and those between the ages of 25 and 29. In 2007/08 staff reported significantly lower rates of drug use than staff in 2001. Last year drug use for the sample in 2007/08 was 19% compared to 27% for the 2001 sample. While drug-using staff compared to non drug-using staff reported more observations of drug use among guests, they were less inclined to intervene. Overall, staff reported restrictive attitudes towards drugs. Conclusions The prevalence of life-time and last year drug use among staff at licensed premises is high compared to the general population in Sweden. Lower rates of self-reported drug use among staff were reported in 2007/08. The results of this study highlight that staff at licensed premises represent an important target population in club drug prevention programs. PMID:21299852

    Some of the ideas of Sigmund Freud were preceded in a literary form by the Swedish writer August Strindberg in the late 19th century. Psychoanalysis itself was introduced in Sweden about a decade into the 20th century by two rivalling pioneers, the doctors Emanuel af Geijerstam and Poul Bjerre. After a slow start, the Danish-Norwegian Psychoanalytical Society and the Finnish-Swedish Psychoanalytical Society were formed in 1934 in Stockholm. The same year, Ericastiftelsen [The Erica Foundation], a psychotherapeutic clinic for children, was founded by Hanna Bratt. Five years later, in 1939, also in Stockholm, the organization that was to become St. Lukasstiftelsen [The Saint Luke's Foundation] was founded. It has been, and still is, an association that has trained psychodynamic psychotherapists, with a focus on existential, religious and philosophical questions. Today, St. Luke's tries to be up-dated from an academic standpoint. During the Second World War, several important psychoanalysts came to Sweden, for example René de Monchy, Lajos and Edith Székely, and Stefi Pedersen. Ola Andersson's doctoral dissertation ("Studies in the Prehistory of Psychoanalysis", 1962) and the historian Gunnar Brandell's essay ("Freud, a Man of His Century", 1961) have had an international impact. In the last two decades, an authorized and carefully edited translation of Freud's collected works has been published by Natur och Kultur, and the history of psychoanalysis in Sweden has been written at the University of Gothenburg. As a result of a recent interest in the work of Jacques Lacan, and French psychoanalysis, philosophy and literature, the journal Psykoanalytisk Tid/Skrift was founded in 2002, in Gothenburg. Since 2011 the journal is called Arche. The largest organized group of psychoanalysts in Sweden today is the Swedish Psychoanalytical Association (SPAF), which has around 225 members. Since 2008, it no longer has the right to license psychotherapists, a situation which

    In 1985, Sweden's population stood at 8.4 million, with an annual growth rate of 0.2%. The infant mortality rate was 6.4/1000, and life expectancy was 76 years for men and 82 years for women. The gross domestic product was US$100.2 billion, with a per capita income of $11,989. Of the work force of 4.34 million, 4.9% are in agriculture, 29.8% work in industry, 21.3% are employed in the commerce and finance sector, and 43.9% are engaged in services. Among the social problems Sweden faces are the increasingly large proportion of the population over age 65 years and the challenge of integrating immigrants into social and political life while preserving national languages and customs. Development during the 1970s was less favorable than in most comparable countries; however, industrial recovery during the 1980s has restored the competitiveness of Swedish exports. There is general agreement that investment in new plants and machinery must be increased and wages and consumption must be moderated if Sweden is to expand its industrial sector. PMID:12177946

    In developed nations people spend about 90% of their time indoors. The relationship between indoor and outdoor air pollution levels is important for the understanding of the health effects of outdoor air pollution. Although other studies describe both the outdoor and indoor atmospheric environment, few excluded a priori major indoor sources, measured the air exchange rate, included more than one micro-environment and included the presence of human activity. PM 2.5, soot, NO 2 and the air exchange rate were measured during winter and summer indoors and outdoors at 18 homes (mostly apartments) of 18 children (6-11-years-old) and also at the six schools and 10 pre-schools that the children attended. The three types of indoor environments were free of environmental tobacco smoke and gas appliances, as the aim was to asses to what extent PM 2.5, soot and NO 2 infiltrate from outdoors to indoors. The median indoor and outdoor PM 2.5 levels were 8.4 μg m -3 and 9.3 μg m -3, respectively. The median indoor levels for soot and NO 2 were 0.66 m -1 × 10 -5 and 10.0 μg m -3, respectively. The respective outdoor levels were 0.96 m -1 × 10 -5 and 12.4 μg m -3. The median indoor/outdoor (I/O) ratios were 0.93, 0.76 and 0.92 for PM 2.5, soot and NO 2, respectively. Their infiltration factors were influenced by the micro-environment, ventilation type and air exchange rate, with aggregated values of 0.25, 0.55 and 0.64, respectively. Indoor and outdoor NO 2 levels were strongly associated ( R2 = 0.71), followed by soot ( R2 = 0.50) and PM 2.5 ( R2 = 0.16). In Stockholm, the three major indoor environments occupied by children offer little protection against combustion-related particles and gases in the outdoor air. Outdoor PM 2.5 seems to infiltrate less, but indoor sources compensate.

    Public interest focuses on whether the superpowers will eventually agree to reduce their strategic nuclear arsenals by 50% or better, and on whether Star Wars should be bargained away or preserved at all costs. Yet progress in arms control quietly proceeded in Stockholm at the multilateral Conference on Confidence- and Security-Building Measures and Disarmament in Europe (CDE), convened on January 17, 1984. The Conference examined ways to reduce the risks of war, but not arbitrarily lowering weapons levels or restricting the deployment of certain systems. Rather, the goal is to lower these risks by clarifying politico-military intentions and regulating the uses of military activities by means of confidence- and security-building measures. Through information exchange, observation, and inspection, along with operational restraints on military activities, these measure seek to diminish the opportunities for wars to start by surprise attack, miscalculation, or accident, and to inhibit the threat or indirect use of force for political intimidation. 2 references.

    This paper investigates the potential temporal and spatial variations of suicides in subway stations in Stockholm, Sweden. The study also assesses whether the variation in suicide rates is related to the station environments by controlling for each station's location and a number of contextual factors using regression models and geographical information systems (GIS). Data on accidents are used as references for the analysis of suicides. Findings show that suicides tend to occur during the day and in the spring. They are concentrated in the main transportation hubs but, interestingly, during off-peak hours. However, the highest rates of suicides per passenger are found in Stockholm's subway stations located in the Southern outskirts. More than half of the variation in suicide rates is associated with stations that have walls between the two sides of the platform but still allow some visibility from passers-by. The surrounding environment and socioeconomic context show little effect on suicide rates, but stations embedded in areas with high drug-related crime rates tend to show higher suicide rates.

    There has been much recent attention to the relationship between the construction of place, identity, and the body. This paper examines some of these themes in a presentation of the gay leather scene in Stockholm, Sweden. Based on ethnography of Stockholm's only true leather club, it shows how identity and spatial location are implicated in one another. It also looks at social and cultural processes of containment and dispersion within leather culture, the creation of erotic bodies, and forms of erotic interaction. These processes are seen as reflecting features of the wider Swedish gay scene and society in general, which is sometimes less tolerant than it is imagined to be. Aspects of current and possible future transformations of leather culture and style are also briefly considered.

    In a brief survey the work of Swedish porphyrinologists through time is presented, from the organic chemist Jakob Berzelius 1840 to the molecular biologists of today. The building up in Stockholm of a Swedish national competence centre for porphyria is touched upon and the emergence of a computerized national register on the porphyria gene carriers in the country described. Figures for the prevalences of the seven different forms of porphyria diagnosed in Sweden are given. The geographical distribution of gene mutation spectra is shown for the most frequent form, acute intermittent porphyria. The organisation at Porphyria Centre Sweden of its diagnostic and consultative services is described, as is the decentralized model for porphyria care applied in the form of a clinical network covering the long and sparsely populated country. The ideas and activities of the Swedish Porphyria Patients' Association are presented. Its focus on protection-by-information of the porphyria gene carrier against maltreatment in health service contacts, and against other exposures to environmental threats to his or her health, is discussed. The combined efforts of the national porphyria centre and the patients' association have resulted in early and accurate diagnosis of most of the porphyria gene carriers in the country. The information to the carriers and to the health service regarding the mechanisms of the diseases and the importance of avoiding exposure to disease triggering environmental factors have greatly reduced porphyric morbidity. In the case of the acute porphyrias, by this programme and after the introduction of heme arginate in the therapy, mortality in the acute phase has become extremely rare in Sweden. In contrast, probably due to greater awareness of the high risk for liver cancer in acute porphyrias the number of hepatoma cases diagnosed has increased.

    Objective Reports of rising prevalence of autism spectrum disorders (ASD), along with their profound personal and societal burden, emphasize the need of methodologically sound studies to explore their causes and consequences. We here present the design of a large intergenerational resource for ASD research, along with population-based prevalence estimates of ASD and their diagnostic validity. Method The Stockholm Youth Cohort is a record-linkage study comprising all individuals aged 0–17 years, ever resident in Stockholm County in 2001–2007 (N = 589,114). ASD cases (N = 5,100) were identified using a multisource approach, involving registers covering all pathways to ASD diagnosis and care, and categorized according to co-morbid intellectual disability. Prospectively recorded information on potential determinants and consequences of ASD were retrieved from national and regional health and administrative registers. Case ascertainment was validated through case-note review, and cross validation with co-existing cases in a national twin study. Results The 2007 year prevalence of ASD in all children and young people was 11.5 per 1,000 (95% confidence interval 11.2–11.8), with a co-morbid intellectual disability recorded in 42.6% (41.0–44.2) of cases. We found 96.0% (92.0–98.4) of reviewed case-notes being consistent with a diagnosis of ASD, and confirmed ASD in 85.2% (66.2–95.8) of affected twins. Conclusions Findings from this contemporary study accords with recently reported prevalence estimates from Western countries at around 1%, based on valid case ascertainment. The Stockholm Youth Cohort, in light of the availability of extensive information from Sweden's registers, constitutes an important resource for ASD research. On-going work, including collection of biological samples, will enrich the study further. PMID:22911770

    Fire training facilities are potential sources of per- and polyfluoroalkyl substances (PFASs) to the nearby environment due to the usage of PFAS-containing aqueous fire-fighting foams (AFFFs). The multimedia distribution of perfluoroalkyl carboxylates (PFCAs), perfluoroalkyl sulfonates (PFSAs), perfluorooctanesulfonamide (PFOSA) and 6:2 fluorotelomer sulfonate (FTSA) was investigated near a fire training facility at Stockholm Arlanda Airport in Sweden. The whole body burden of PFASs in European perch (Perca fluviatilis) was 334±80μg absolute and was distributed as follows: Gonad>liver≈muscle>blood>gill. The bioconcentration factor (BCF) and sediment/water partition coefficient (Kd) increased by 0.6-1.7 and 0.2-0.5 log units, respectively, for each additional CF2 moiety for PFCAs and PFSAs. PFAS concentrations in water showed no significant decreasing trend between 2009 and 2013 (p>0.05), which indicates that Stockholm Arlanda Airport may be an important source for long-term contamination of the nearby environment with PFASs.

    This study evaluated the effects of a community alcohol prevention program on the frequency of alcohol service to young adults at licensed premises in Stockholm, Sweden. We used a pretest (1996)-posttests (1998 and 2001) design with intervention and control areas. The multicomponent intervention combines training of serving staff in responsible beverage service, policy initiatives, and enforcement of existing alcohol regulations. Adolescents 18 years old (the legal drinking age on licensed premises in Sweden), but younger looking according to an expert panel, visited licensed premises in pairs, where each adolescent ordered a beer. At baseline in 1996, the adolescents made 600 attempts to order. At follow-up in 1998, the number of attempts to order was 252, and at the second follow-up in 2001, the adolescents made 238 attempts. We found no statistically significant differences between the intervention and control areas. Overall, the frequency of alcohol service to adolescents on licensed premises in these areas of Stockholm decreased significantly over time, from 45 to 41 and to 32%, in 1996, 1998, and 2001, respectively. The decrease in alcohol service in 2001 was statistically significant compared to the baseline in 1996. One explanation for this improvement could be more effective enforcement of existing alcohol laws in both the intervention and control areas. We also found that licensed premises that used doormen to screen potential customers were less likely to sell to minors.

    We investigated the risk of stroke related to long-term ambient air pollution exposure, in particular the role of various exposure time windows, using four cohorts from Stockholm County, Sweden. In total, 22,587 individuals were recruited from 1992 to 2004 and followed until 2011. Yearly air pollution levels resulting from local road traffic emissions were assessed at participant residences using dispersion models for particulate matter (PM10) and nitrogen oxides (NOX). Cohort-specific hazard ratios were estimated for time-weighted air pollution exposure during different time windows and the incidence of stroke, adjusted for common risk factors, and then meta-analysed. Overall, 868 subjects suffered a non-fatal or fatal stroke during 238,731 person-years of follow-up. An increment of 20 μg/m3 in estimated annual mean of road-traffic related NOX exposure at recruitment was associated with a hazard ratio of 1.16 (95% CI 0.83–1.61), with evidence of heterogeneity between the cohorts. For PM10, an increment of 10 μg/m3 corresponded to a hazard ratio of 1.14 (95% CI 0.68–1.90). Time-window analyses did not reveal any clear induction-latency pattern. In conclusion, we found suggestive evidence of an association between long-term exposure to NOX and PM10 from local traffic and stroke at comparatively low levels of air pollution. PMID:25827311

    Carbon-containing particles have deleterious effects on both Earth's climate and human health. In Europe, the main sources of light-absorbing carbon (LAC) emissions are the transport (67%) and residential (25%) sectors. Information on the spatiotemporal variability of LAC particles in urban areas is relevant for air quality management and to better diagnose the population exposure to these particles. This study reports on results of an intensive field campaign conducted at four sites (two kerbside stations, one urban background site and a rural station) in Stockholm, Sweden, during the spring 2006. Light-absorbing carbon mass concentrations (MLAC) were measured with custom-built Particle Soot Absorption Photometers (PSAP). The spatiotemporal variability of MLAC concentrations was explored by examining correlation coefficients (R), coefficients of divergence (COD), and diurnal patterns at all sites. Simultaneous measurements of NOx, PM10, PM2.5, and meteorological variables were also carried out at the same locations to help characterize the LAC emission sources. Hourly mean and standard deviation MLAC concentrations ranged from 0.36 (rural) to 5.39 μg m-3 (street canyon) and from 0.50 to 3.60 μg m-3, respectively. Concentrations of LAC between urban sites were poorly correlated even for daily averages (R<0.70), combined with highly heterogeneously distributed concentrations (COD>0.30) even at spatial scales of few kilometers. This high variability is connected to the distribution of emission sources and processes contributing to the LAC fraction at these sites. At urban sites, MLAC tracked NOx levels and traffic density well and mean MLAC/PM2.5 ratios were larger (26-38%) than at the background sites (4-10%). The results suggest that vehicle exhaust emissions are the main responsible for the high MLAC concentrations found at the urban locations whereas long-range transport (LRT) episodes of combustion-derived particles can generate a strong increase of levels at

    Ockelbo disease, caused by a Sindbis-related virus transmitted to man by mosquitoes, was first described in the central part of Sweden in the 1960s as clusters of patients with fever, arthralgia and rash. An average annual rate of 30 cases was recorded in the 1980s but no cases have been diagnosed during the last few years. Nephropathia epidemica (NE) characterized by fever, abdominal pain and renal dysfunction has been known to cause considerable morbidity in Sweden during the last 60 years but the etiologic agent (Puumala virus) was not isolated until 1983. This virus's main reservoir is the bank vole (Clethrionomys glareolus). NE is endemic in the northern two thirds of Sweden where more than a hundred cases are diagnosed each year. Tick-borne encephalitis transmitted by Ixodes ricinus ticks is restricted to the archipelago and Lake M-alaren on the east coast close to Stockholm. Between 30 and 110 cases are diagnosed every year. Inkoo virus, a California encephalitis group virus, has been isolated from mosquitoes in Sweden. The antibody prevalence to Inkoo virus is very high in a normal population, but no disease has as yet been associated with this virus in Sweden. Among the vector-borne virus diseases imported to Sweden, dengue is the most important, with approximately 50 cases recorded every year.

    Ozone, PM10 and PM2.5 concentrations over Paris, France and Stockholm, Sweden were modelled at 4 and 1 km horizontal resolutions respectively for the present and 2050 periods employing decade-long simulations. We account for large-scale global climate change (RCP-4.5) and fine-resolution bottom-up emission projections developed by local experts and quantify their impact on future pollutant concentrations. Moreover, we identify biases related to the implementation of regional-scale emission projections by comparing modelled pollutant concentrations between the fine- and coarse-scale simulations over the study areas. We show that over urban areas with major regional contribution (e.g. the city of Stockholm) the bias related to coarse-scale projections may be significant and lead to policy misclassification. Our results stress the need to better understand the mechanism of bias propagation across the modelling scales in order to design more successful local-scale strategies. We find that the impact of climate change is spatially homogeneous in both regions, implying strong regional influence. The climate benefit for ozone (daily mean and maximum) is up to -5 % for Paris and -2 % for Stockholm city. The climate benefit on PM2.5 and PM10 in Paris is between -5 and -10 %, while for Stockholm we estimate mixed trends of up to 3 % depending on season and size class. In Stockholm, emission mitigation leads to concentration reductions up to 15 % for daily mean and maximum ozone and 20 % for PM. Through a sensitivity analysis we show that this response is entirely due to changes in emissions at the regional scale. On the contrary, over the city of Paris (VOC-limited photochemical regime), local mitigation of NOx emissions increases future ozone concentrations due to ozone titration inhibition. This competing trend between the respective roles of emission and climate change, results in an increase in 2050 daily mean ozone by 2.5 % in Paris. Climate and not emission change

    Background Cardiometabolic risk factors and related cardiovascular diseases represent major threats to healthy aging. Objective We aimed to estimate distribution, pharmacological treatment, and control of main cardiometabolic risk factors among older people. Methods This population-based study included 3363 participants (age≥60 years, 64.9% women) in the Swedish National study on Aging and Care in Kungsholmen, in central Stockholm, Sweden (2001-2004). Data on demographics, cardiometabolic risk factors (hypertension, obesity, diabetes, and high cholesterol), and medication use were collected through face-to-face interviews, clinical examinations, laboratory tests, and the inpatient register. Cardiometabolic risk factors were defined following the most commonly used criteria. Prevalence was standardized using local census data. Results The age- and sex-standardized prevalence of diabetes, obesity, high cholesterol, and hypertension was 9.5%, 12.8%, 49.7%, and 74.9%, respectively. The prevalence of hypertension and diabetes increased with age, whereas the prevalence of obesity and high cholesterol decreased with age. Forty-nine percent of older adults had two or more cardiometabolic risk factors; 9.8% had three or more. Overall, 55.5% of people with hypertension, 50.3% with diabetes, and 25.0% with high cholesterol received pharmacological treatment. Of those treated pharmacologically, 49.4%, 38.1%, and 85.5% reached therapeutic goals for hypertension (blood pressure<150/90 mmHg), diabetes (glycated haemoglobin<7%), and high cholesterol (total cholesterol<6.22 mmol/l), respectively. Conclusions Hypertension, high cholesterol, and clustering of cardiometabolic risk factors were common among older people in Stockholm, but pharmacological treatment and control of these major factors can be improved. Appropriate management of cardiometabolic profiles among older people may help improve cardiovascular health and achieve healthy aging. PMID:25799502

    The purpose of this work was to apply acoustic inversion to a bay in the Stockholm archipelago with strong variations of the bottom both vertically and horizontally. The inversions were based on measurements undertaken in May 2001 of transmission loss over a 2.5 km long track. The bottom parameters were estimated by minimizing the difference between simulated and measured data. The parabolic wave equation was used as a wave propagation model and the inversions were carried out by a genetic algorithm. They resulted in a relatively good fit. The inverted bottom parameters were also evaluated by model predictions against a control data set of other frequencies than those of the inversion. The agreement between the estimated and measured parameters was good.

    Acute aseptic meningitis (AAM) affects 10-20/100,000 inhabitants per years in Sweden. Up to the beginning of the 1980s the diagnoses were made by virus isolation and/or determination of viral antibodies in serum. The development of PCR for detection of viruses in CSF samples has increased the sensitivity and diagnostic efficiency considerably. We investigated the aetiology of AAM and the diagnostic efficiency in an adult population in Stockholm, using a limited first-line combination of microbiological assays. CSF and serum samples, consecutively collected in 419 patients with clinical symptoms of AAM in northern Stockholm during 1999-2004, were included. PCR assays for herpes simplex virus (HSV) DNA and enterovirus (EV) RNA in the CSF as well as ELISA for IgM in serum to tick-borne encephalitis virus (TBEV) were performed routinely. A viral diagnosis was obtained in 255 of the 419 cases (62%) with these routinely performed assays. Clinical findings in combination with additional diagnostic tests resulted in an overall aetiological yield of 72%. EV was the major causative agent (27%) followed by TBEV (21%) and HSV-2 (19%). We conclude that consistent use of CSF-PCR for EV and HSV and TBEV serology established a diagnosis in the majority of AAM patients.

    The prevalence of hepatitis B virus (HBV) markers and exposure to risks possibly associated with HBV transmission were investigated in 797 health care workers (HCW) from Stockholm. Altogether, 31/797 (3.9%) persons were positive for at least one HBV marker, 8.0, 7.9 and 6.4% respectively of children's nurses, laboratory assistants and psychiatric assistant nurses. A history of exposure to needle-stick injuries from any patient, was more often obtained from HCW with HBV markers than from HCW without such markers. The prevalence of HBV markers increased with age and duration of occupation in health care. Most HCW had been exposed to at least one occupational risk for HBV transmission early in their professional careers. Although the risk of acquiring HBV at present is low, the virus constitutes a potential occupational hazard for non-vaccinated HCW in Stockholm, a risk which may increase in the future since the number of chronic HBsAg carriers is increasing in Sweden.

    Understanding about socio-cultural differences in physical activity in children with high and low risk for obesity can help tailor intervention programs in different settings. This study aimed to compare objectively measured physical activity in two-year-olds and their parents, living in Stockholm, Sweden, and Wuhan, China. Data from Early STOPP was used. Children and parents wore an accelerometer in connection with the child's second birthday. Weekly and hourly patterns were examined. Correlation between child and parental physical activity was assessed. Data on 146 Swedish and 79 Chinese children and their parents was available. Children, mothers and fathers in Stockholm were significantly more active than their counterparts in Wuhan (children; 2989 (SD 702) vs. 1997 (SD 899) counts per minute (CPM), mothers 2625 (SD 752) vs. 2042 (SD 821) CPM; fathers 2233 (SD 749) vs. 1588 (SD 754) CPM). Activity levels were similar over a week for children and parents within both countries. No parental-child correlations, except for a paternal-son correlation in Stockholm, were found. Children, mothers and fathers in Stockholm are more active compared with their counterparts in Wuhan. Interventions to increase physical activity needs to take cultural aspects into account, also when targeting very young children. PMID:27404563

    U.S. Department of Energy’s National Nuclear Security Administration (NNSA) Office of Global Threat Reduction (GTRI) recently removed legacy plutonium materials from Sweden in collaboration with AB SVAFO, Sweden. This paper details the activities undertaken through the U.S. receiving site (Savannah River Site (SRS)) to support the characterization, stabilization, packaging and removal of legacy plutonium materials from Sweden in 2012. This effort was undertaken as part of GTRI’s Gap Materials Program and culminated with the successful removal of plutonium from Sweden as announced at the 2012 Nuclear Security Summit. The removal and shipment of plutonium materials to the United States was the first of its kind under NNSA’s Global Threat Reduction Initiative. The Environmental Assessment for the U.S. receipt of gap plutonium material was approved in May 2010. Since then, the multi-year process yielded many first time accomplishments associated with plutonium packaging and transport activities including the application of the of DOE-STD-3013 stabilization requirements to treat plutonium materials outside the U.S., the development of an acceptance criteria for receipt of plutonium from a foreign country, the development and application of a versatile process flow sheet for the packaging of legacy plutonium materials, the identification of a plutonium container configuration, the first international certificate validation of the 9975 shipping package and the first intercontinental shipment using the 9975 shipping package. This paper will detail the technical considerations in developing the packaging process flow sheet, defining the key elements of the flow sheet and its implementation, determining the criteria used in the selection of the transport package, developing the technical basis for the package certificate amendment and the reviews with multiple licensing authorities and most importantly integrating the technical activities with the Swedish partners.

  14. Patterns of Suicide and Other Trespassing Fatalities on State-Owned Railways in Greater Stockholm; Implications for Prevention

    2012-01-01

    Each year, approximately 80–100 people are killed on state-owned railways due to train-person collisions in Sweden. Underlying causes are suicide and accidents; suicide constituting a vast majority. Earlier Swedish studies at a national level revealed a relation between population density and incident frequency, however, with places of occurrence often located to the outskirts of cities some distance away from station areas where victims can await approaching trains in seclusion. The aim of this study was to investigate whether this national pattern also applies to larger urban areas such as greater Stockholm, and to discuss preventative implications based on these observations. All registered incidents (N = 41) where people were hit or run-over by trains with a fatal outcome over the four-year period 2005–2008 were investigated. Results deviating from the national pattern include that most incidents occur at station areas, and that most victims enter the tracks from platforms. Passing express trains appear to be overrepresented, compared to commuter trains. Due to a low number of cases, our observations must be interpreted with caution. However, they imply that preventative measures in this type of area should focus on platform safety foremost, especially protection against rapid trains passing by station areas. PMID:22690162

    Toxoplasma gondii is a zoonotic protozoan parasite, infecting a wide range of warm-blooded animals. The Swedish wild boar population is expanding and increased hunting provides its meat to a growing group of consumers. We performed a spatio-temporal investigation of T. gondii seroprevalence in Swedish wild boars. An ELISA was set up and evaluated against a commercial direct agglutination test, using Bayesian latent class analysis. The ELISA sensitivity and specificity were estimated to 79% and 85%, respectively. Of 1327 serum samples, 50% were positive. Thirty-four per cent of young wild boars and 55% of adults were positive (P < 0.001). The total seroprevalence ranged from 72% in 2005 to 38% in 2011 (P < 0.001), suggesting a declining trend. The highest seroprevalence, 65%, was recorded in South Sweden. In other regions it varied from 29% in Stockholm to 46% in East Middle Sweden.

  16. Group Psychotherapy in Sweden.

    PubMed

    Ahlin, Göran

    2015-10-01

    The paper presents an overview of the national developments of group psychotherapy (GPS) in Sweden during the period from World War II until the present time. Methods and concepts, imported primarily from England and the United States, inspired trainings and widespread psychodynamic and group analytic applications in schools, health treatment, and social care. Education in psychotherapy and GPS at universities opened new therapeutic and vocational areas during the period 1970-2005. Increasing criticism of psychodynamics, as in other Western societies, but more radical in Sweden, has in the last decades made group analytic GPS diminish in favor of cognitive behavioral therapy models. Prospects for GPS further development may presently look bleak but, in a longer perspective, are promising.

    This study describes the epidemiology and symptoms in 271 cryptosporidiosis patients in Stockholm County, Sweden. Species/genotypes were determined by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) of the Cryptosporidium oocyst wall protein (COWP) and 18S rRNA genes. Species were C. parvum (n=111), C. hominis (n=65), C. meleagridis (n=11), C. felis (n=2), Cryptosporidium chipmunk genotype 1 (n=2), and a recently described species, C. viatorum (n=2). Analysis of the Gp60 gene revealed five C. hominis allele families (Ia, Ib, Id, Ie, If), and four C. parvum allele families (IIa, IIc, IId, IIe). Most C. parvum cases (51%) were infected in Sweden, as opposed to C. hominis cases (26%). Clinical manifestations differed slightly by species. Diarrhoea lasted longer in C. parvum cases compared to C. hominis and C. meleagridis cases. At follow-up 25-36 months after disease onset, 15% of the patients still reported intermittent diarrhoea. In four outbreaks and 13 family clusters, a single subtype was identified, indicating a common infection source, which emphasizes the value of genotyping for epidemiological investigations.

  18. Sweden considers wind power

    During 1988, Sweden increased its number of wind generating facilities from 13 to 22, reflecting a new attitude toward wind power developing in the country. Last fall, a 750 kW wind turbine installed in the archipelago of Gothenburg was connected to the grid. The turbine is the biggest in use in Sweden, operated and maintained by the local energy authority of Gothenburg. Most turbines being manufactured have a capacity of 20 to 200 kW. The Maglarp turbine in the south of Sweden has a capacity of 3,000 kW, and the Naesudden turbine on an island in the Baltic Sea has 2,000 kW. The two projects are considered experimental by the owner, Vattenfall, the State Power Board. On the basis of energy production, Maglarp may be the largest in the world. Its highest production, 4,400 MWh, was achieved in 1988. In January 1989, the production was 900 MWh, the third highest monthly production so far since September 1983. The State Power Board, the members of the Swedish Power Association, Sydkraft, together with a number of municipal power companies and stations, have formed the Swedish Energy Development Corporation, SWEDCO. One goal for the new corporation is to include wind power in the Swedish energy system. SWEDCO will provide economic and operation data to pursue wind technology.

  19. Age at immigration and crime in Stockholm using sibling comparisons.

    Beckley, Amber L

    2015-09-01

    Past Swedish research has shown that immigrants arriving in the receiving country at an older age are less likely to commit crime than immigrants arriving at a younger age. Segmented assimilation theory argues that the family and neighborhood may be important factors affecting how age at immigration and crime are related to one another. This study used population-based register data on foreign-background males from Stockholm to test the effect of age at immigration on crime. Potential confounding from the family and neighborhood was addressed using variables and modeling strategies. Initial results, using variables to control for confounding, showed that people who immigrated around age 4 were the most likely to be suspected of a crime. When controlling for unmeasured family characteristics, it seemed that a later age at immigration was tied to a lower likelihood of crime, which does not corroborate past research findings. The effect of age at immigration, however, was not statistically significant. The results imply that future research on entire families may be a worthwhile endeavor. PMID:26188451

    Many environmental risks and societal concerns are directly related to the way we manage our land and water environments. The two-year master's programme "Hydrology, Hydrogeology and Water Resources" at Stockholm University, Sweden, is based on a system perspective and provides extended knowledge about water and soil-rock-sediment systems and how these interact with each other and with land use, socio-economic and water resource policy and management systems. This water system perspective includes the spreading of dissolved substances and pollutants in various water systems and associated risks for society. Questions related to water resources are also covered: the management of water resources and conflicts as well as collaborations caused by shared water resources on local, regional and global scales. A common learning objective for the courses in the programme is to be able to identify, extract and combine relevant information from databases and scientific publications, and use the resulting dataset in hydrological, hydrogeological and water resources analyses, on local, regional or global levels. Traditional classroom teaching is to large extent complemented by case study analyses, performed as project assignments. The importance of water resources for both the society and the environment is emphasized through applications to practical water resources management challenges in society. The courses in this program include the following topics: · Hydrological and hydrogeological processes, main components of the water cycle (e.g., precipitation, evapotranspiration, discharge) and the spreading of dissolved substances and pollutants in various water systems. · Water resources and water quality, pollution spreading through surface, ground and coastal water systems, as well as vulnerability and resilience of water resources. · Regional analyses related to global water resource vulnerability and resilience. · Models and information systems as important tools for

    One hundred thirty-three Clostridium difficile strains were collected from 71 patients and analyzed for the presence of C. difficile toxin B by the cell cytotoxicity neutralization assay, genes for toxin A, toxin B, binary toxin and TcdC deletion by PCR. All strains were also PCR-ribotyped and analyzed for sporulation frequency. The MICs of the isolates were determined against cadazolid and seven other antimicrobial agents by the agar dilution method. All isolates were positive for toxin B by the cell cytotoxicity neutralization assay. One hundred fourteen isolates were positive for toxin A and B and 16 isolates were positive for toxin A, toxin B and binary toxin by PCR. Three isolates were negative for toxin A but positive for toxin B. Thirty-three different ribotypes were identified. No strain of ribotype 027 was found. No differences in sporulation were noticed between the primary and recurrent isolates. All 133 isolates were sensitive to cadazolid (0.064-0.5 mg/l), fidaxomicin (0.008-0.125 mg/l), metronidazole (0.125-2 mg/l), vancomycin (0.125-1 mg/l) and tigecycline (0.032-0.25 mg/l). Three isolates were resistant to linezolid (8 mg/l), 15 isolates were resistant to moxifloxacin (8-32 mg/l) and 103 isolates were resistant to clindamycin (8-256 mg/l). No association between toxins A, B and binary toxin, ribotypes or the sporulation and the sensitivity to cadazolid could be found. Cadazolid has a potent in vitro activity against C. difficile.

    Since the discovery of the first planet, orbiting a sun-like star outside of our solar system, astronomy has changed dramatically. This event inspired a wide spectrum of activities not just in observational astronomy but in all fields related to planets from star formation to astrobiology. The discovery itself was the result of long and systematic work on perfecting measuring techniques and collecting data. Once the required level of precision was reached news about extrasolar planets started to appear frequently not just in scientific journals but also in the general media. Although fast progress is quite obvious in many areas related to planetary sciences for this Nobel symposium, dedicated to the Physics of Planetary Systems, we selected five topics where a number of particularly important breakthroughs happened in the last decade. These are: detection of exoplanets planet birthplaces: observations and modelling planet formation evolution of planetary systems planet characterization. We dedicated a full session, consisting of a few review talks and a joint discussion, to each of these topics. The format was a success, but what made this meeting so remarkable was the quality of the talks. We are very thankful to the world leading scientists for coming to Lidingö and making this symposium a truly memorable event. This book contains most of their contributions for you to enjoy. We are very thankful to the Nobel Foundation for generous sponsorship which made this symposium possible.

  4. Shallow water radio-magnetotelluric (RMT) measurements in urban environment: A case study from Stockholm city

    The Radio-MagnetoTelluric (RMT) method uses the electromagnetic signal from distant radio transmitters in the frequency range 15 to 250 kHz. RMT applications in near-surface studies have already been well established. Two components of electric field and three components of magnetic field are measured. These measured components are related to each other via transfer functions which contain detailed information about the variation of electrical resistivity of the subsurface. The present study is carried out in the frame of TRUST (TRansparent Underground STructure) project supported by several research and public organizations as well as industry. The study area is located close to central Stockholm in Sweden where the Swedish traffic authority has planned to construct a 21-km long motorway to bypass the city. In order to reduce the impact on natural and cultural environments, 18 km of the motorway will be located in tunnels. The main objective of this study is thus to identify potential fracture zones and faults as well as the general geological settings. The proposed path of the tunnel partly passes under the Lake Mälaren at a depth of about 60 m. Thus a challenge was posed on the applicability of RMT method in shallow water environments. Successful applications of RMT measurements using the Uppsala University's EnviroMT system on land encouraged us to modify the system to acquire data over lake water especially in urban areas. Pioneered by the Geological Survey of Sweden (SGU), RMT data were collected over the Lake Mälaren in spring 2012. The prototype acquisition system did not only turn out to be appropriate for such a challenging environment, but it was also much more efficient as compared with land surveys. Fifty two lines including 1160 stations with an average spacing of 15 m were covered in three days. Cultural noise associated with the city-related environment had to be identified and filtered out before inversion could be carried out. Reliable estimates

    Studies were carried out in Japan, United States, and Sweden regarding comparability of analytical methods for cadmium, daily intake of cadmium via food, daily amount of cadmium in feces, concentrations of cadmium in different tissues and the body burden of cadmium, urinary excretion of cadmium and cadmium concentrations in blood. It was found that the cadmium intake via food among adults is about 35 μg/day in Japan (Tokyo) and about 17 μg/day in the U.S. (Dallas) and Sweden (Stockholm). It varies with age in a way similar to calorie intake. Body burden increases rapidly with age. The half-time of cadmium is longer in muscles than in liver or kidneys. In the cross-sectional population samples studied (smokers and nonsmokers mixed) the average cadmium body burden at age 45 was about 21 mg in Japan, 9 mg in the U.S., and 6 mg in Sweden. Among nonsmokers in the U.S. and Sweden the body burden at age 45 was about 5–6 mg. The difference in average body burden for smokers and nonsmokers is explained by differences in smoking habits. Cadmium excretion in urine was closely correlated with body burden and about 0.005–0.01% of body burden is excreted daily in urine. Cadmium concentration in the blood was a good indicator of average recent intake over a 3-month period. Neither blood cadmium nor urine cadmium changed immediately after an increase of exposure level. PMID:226355

    In ICOS Sweden, all 6 sites are equipped with a novel, standardized system for high-quality measurements of greenhouse gas concentrations and fluxes of energy and greenhouse gases along with environmental variables needed to understand the underlying ecosystem processes. Turbulent fluxes are determined from 20-Hz data of wind components and scalar concentrations, all sampled digitally and synchronously by a newly developed digital datalogger (ISDL). Vertical concentration gradients of greenhouse gases are measured by an infrared gas analyzer through a multi-level air sampling system. Relevant components of the radiation balance are measured at different levels above ecosystems as well as along transects below forest canopies. To determine energy storage within vegetation, a large number of thermocouples are installed in different parts of selected trees. At several locations in each ecosystem, groundwater level and depth profiles of soil temperature and soil water content are measured. Meteorological driving variables such as air temperature profiles, air pressure, and precipitation are also measured at each site. With regard to the long-term perspective of ICOS RI, the entire measurement system is constructed with emphasis on reliability, durability, and robustness with respect to wearing and strain caused by harsh Nordic environment. In particular, a specialist lightning protection system efficiently prevents instrument damage and data gaps. Fulfilling these needs, the ICOS Sweden system represents the high end of technological requirements for measurement systems in all European regions and climatic zones, providing a new standard for harmonized data collection along climatic and geographic transects.

    Sweden was one of the first European Union countries that saw the opportunity in the free movement of professionals. First offers for jobs were managed in 2000. Since then, a large number of professionals have taken the opportunity of a decent job and have moved from Spain to Sweden. The Swedish health care model belongs to the group of national health systems. The right to health care is linked to legal citizenship. Health is financed through regional taxes, but there is a compulsory co-payment regardless of the financial situation of the patient. The provision of health care is decentralised at a regional level, and there is a mixture of private and public medical centres. Primary care is similar to that in Spain. Health professionals work as a team with a division of tasks. Like in Spain, waiting lists and coordination between primary and specialised care are a great problem. Patients may register with any public or private primary care centre and hospital provider within their region. Access to diagnostic tests and specialists are restricted to those selected by specialists. Doctors are salaried and their job and salary depend on their experience, professional abilities and regional needs. Medicine is curative. General practitioners are the gateway to the system, but they do not act as gatekeeper. Hospitals offer a number of training post, and the access is through an interview. Continuing medical education is encouraged and financed by the health centre in order to increase its revenues.

    2010-12-01

    In this paper, a genetic algorithm optimisation method has been used to develop an improved rail profile for Stockholm underground. An inverted penalty index based on a number of key performance parameters was generated as a fitness function and vehicle dynamics simulations were carried out with the multibody simulation package Gensys. The effectiveness of each profile produced by the genetic algorithm was assessed using the roulette wheel method. The method has been applied to the rail profile on the Stockholm underground, where problems with rolling contact fatigue on wheels and rails are currently managed by grinding. From a starting point of the original BV50 and the UIC60 rail profiles, an optimised rail profile with some shoulder relief has been produced. The optimised profile seems similar to measured rail profiles on the Stockholm underground network and although initial grinding is required, maintenance of the profile will probably not require further grinding.

    The association between unemployment rates and population mental health has been studied with contradictory results. We examine the association between unemployment and antidepressants in Stockholm County. Age- and sex-specific monthly data on unemployment and dispensed prescribed antidepressants from January 1998 to January 2008 in Stockholm County were used. The association was studied with bivariate cointegration analysis with stationarity check of the residuals. We found that dispensing of antidepressants was inversely associated with unemployment. One interpretation is that antidepressants have not followed decreasing unemployment rates.

    Jonsson, E.B.

    1997-08-01

    The conversion of the Swedish 50 MW R2 reactor from HEU to LEU fuel has been successfully accomplished over a 16 cycles long process. The conversion started in January 1991 with the introduction of 6 LEU assemblies in the 8*8 core. The first all LEU core was loaded in March 1993 and physics measurements were performed for the final licensing reports. A total of 142 LEU fuel assemblies have been irradiated up until September 1994 without any fuel incident. The operating licence for the R2 reactor was renewed in mid 1994 taking into account new fuel type. The Swedish Nuclear Inspectorate (SKI) pointed out one crucial problem with the LEU operation, that the back end of the LEU fuel cycle has not yet been solved. For the HEU fuel Sweden had the reprocessing alternative. The country is now relying heavily on the success of the USDOEs Off Site Fuels Policy to take back the spent fuel from the research reactors. They have in the meantime increased their intermediate storage facilities. There is, however, a limit both in time and space for storage of MTR-type of assemblies in water. The penalty of the lower thermal neutron flux in LEU cores has been reduced by improvements of the new irradiation rigs and by fine tuning the core calculations. The Studsvik code package, CASMO-SIMULATE, widely used for ICFM in LWRs has been modified to suit the compact MTR type of core.

    Undergraduate medical education in Sweden has moved from nationally regulated, subject-based courses to programmes integrated either around organ systems or physiological and patho-physiological processes, or organised around basic medical science in conjunction with clinical specialities, with individual profiles at the seven medical schools. The national regulations are restricted to overall academic and professional outcomes. The 5½ year long university undergraduate curriculum is followed by a mandatory 18 months internship, delivered by the County Councils. While quality control and accreditation for the university curriculum is provided by the Swedish National Agency for Higher Education, no such formal control exists for the internship; undergraduate medical education is therefore in conflict with EU directives from 2005. The Government is expected to move towards 6 years long university undergraduate programmes, leading to licence, which will facilitate international mobility of both Swedish and foreign medical students and doctors. Ongoing academic development of undergraduate education is strengthened by the Bologna process. It includes outcome (competence)-based curricula, university Masters level complying with international standards, progression of competence throughout the curriculum, student directed learning, active participation and roles in practical clinical education and a national assessment model to assure professional competence. In the near future, the dimensioning of Swedish undergraduate education is likely to be decided more by international demands and aspects of quality than by national demands for doctors.

    This article describes the patient safety work in Sweden and the cooperation between the Nordic countries in the area of patient safety. It depicts the national infrastructure, methods and partners in patient safety work as well as the development in key areas. Since 2000, the interest in patient safety and quality issues has significantly increased. A national study (2009) showed that more than 100,000 patients (8.6 %) experienced preventable harm in hospitals. Since 2007, all Swedish counties and regions work on the "National commitment for increased patient safety" to systematically minimize adverse events in the healthcare system. Also, a national strategy for patient safety has been proposed based on a new law regulating the responsibility for patient safety (2011) and a zero vision in terms of preventable harm and adverse events. The Nordic collaboration in this field currently focuses on the development of indicators and quality measurement with respect to nosocomial infections, harm in inpatient somatic care, patient safety culture, hospital mortality and polypharmacy in the elderly. The Nordic collaboration is driven by the development, exchange and documentation of experiences and evidence on patient safety indicators. The work presented in this article is only a part of the Swedish and the Nordic efforts related to patient safety and provides an interesting insight into how this work can be carried out.

  1. New ways of financing and organizing health care in Sweden.

    PubMed

    Håkansson, S

    1994-01-01

    The health care system in Sweden has been undergoing radical change since 1991. The mainly public financed (90%) system with 26 autonomous counties spent 8.5% of its gross domestic product on health care in 1991. The main features of the 'paradigm shift' are: separation of production and financing; resource allocation to health districts in relation to the needs of the population; and introduction of public competition between health districts (purchasers) and hospitals (providers). The health district boards are responsible for the health care of the population in their district hospitals financed by their activities (e.g. through diagnosis-related groups (DRGs)) and quality aspects monitored by central authorities. A parliamentary committee (HSU 2000) is investigating how Sweden's health care system can be organized and financed in the future. Three models are analyzed: a reformed county council court model, a primary care-managed model, and a compulsory insurance model. Each model must be consistent with equity and public financing. From 1992 in the Stockholm county, five surgical specialties were paid for their activities according to DRGs for inpatient care and another system for outpatient care. The number of treated patients during 1992 increased by 8% in inpatient care, 50% in day surgery and by 15% in outpatient care. Taken together, the activities increased by 11%, which is slightly more than the expected 10% increase in productivity. (There was a 10% decrease in DRG prices from 1 January 1992.) The total costs decreased by 1% due to fewer personnel. Nothing has been reported concerning the quality of care, neither before nor after the model was introduced. From 1993, all somatic acute specialties are paid by DRGs and the equivalent outpatient classification systems. The results from 1993 will be presented in the autumn of 1994.

    As we need knowledge about the prevalence of scientific dishonesty, this study investigates the knowledge of, experiences with, and attitudes toward various forms of scientific dishonesty among PhD students at the main medical faculties in Sweden and Norway. An anonymous questionnaire was distributed to all post-graduate research students attending basic PhD courses at the medical faculties in Stockholm and Oslo during the fall 2014. The responding doctoral students reported to know about various forms of scientific dishonesty from the literature, in their department, and for some also through their own experience. Some forms of scientific misconduct were considered to be acceptable by a significant minority. There was a high level of willingness to report misconduct but little awareness of relevant policies for scientific conduct. PMID:26333685

    The Dala (Älvdalen) Porphyries from Sweden Anders Wikström (retired from Geological Survey of Sweden) Lola Pereira (University of Salamanca, Spain) Thomas Lundqvist (retired from Geological Survey of Sweden) Barry Cooper (University of South Australia) The commercial stone industry in Älvdalen, about 350 km northwest of Stockholm, commenced in the second half of the 18th century, as a consequence of social need. The region had been plagued by severe famine and there was an urgent need for additional wealth-generating industry. At that time it was already known that the porphyry in the area was similar to the "porfido rosso antico" from Egypt which had played an important role in the Roman culture. Many ups and downs followed. During one period in the 19th century, the Swedish Royal family owned the industry. At the same time, several "porphyry" objects were presented to different courts around Europe (e.g. a 4 metre tall vase to the Russian czar, although of a more granitic variety). Otherwise most products have been smaller objects like urns, vases, candelabras, etc. The very hard stone (with variable red or black colours) can be highly polished. Many of the porphyry varieties were sourced from glacial boulders. These had been "mechanically tested" by nature and were free from joints which otherwise was a problem in the associated quarries. Comagmatic granites also occur. The porphyries and granites have an age around 1700 Ma, and the former are amazingly well preserved with magnificent volcanic textures. The porphyries and granites occupy a vast area and are in part covered with red, continental sandstones (which are quarried to-day). In the middle of the 20th century, the ignimbritic character of the porphyry was discovered. Previously, the flattened "fiamme" (collapsed pumice) had been interpreted as some kind of flow structure in a lava. The porphyry manufacturing plants in Älvdalen are a part of the Swedish industrial history. Over a significant

    Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) provide two interlinked platforms for the assessment of impacts on biodiversity caused by human developments. Although it might be too early to draw conclusions on the efficiency of SEA to assess such impacts, a number of persistent problems have been identified in the case of EIA. Some of these shortcomings concern the lack of proper prediction and impact quantification, and the inadequate/insufficient assessment of cumulative effects. A number of problems are related to the scale(s) at which the assessment is performed. SEA may provide a more adequate framework than EIA to discuss scale-related issues (i.e. cumulative impacts) but it also requires the use of adapted tools. This paper presents a case study where a GIS-based habitat model for the lesser spotted woodpecker is tested, validated and applied to a planning scenario in the Stockholm region in Sweden. The results show that the method adopted offers great prospects to contribute to a better assessment of biodiversity-related impacts. Even though some limitations remain in the form of data requirement and interpretation of the results, the model produced continuous, quantified predictions over the study area and provided a relevant basis for the assessment of cumulative effects. Furthermore, this paper discusses potential conflicts between different scales involved in the assessment - related to administrative boundaries, ecological processes, data availability, the method adopted to perform the assessment and temporal aspects.

    Haas, Jan; Furberg, Dorothy; Ban, Yifang

    2015-06-01

    This study investigates urbanization and its potential environmental consequences in Shanghai and Stockholm metropolitan areas over two decades. Changes in land use/land cover are estimated from support vector machine classifications of Landsat mosaics with grey-level co-occurrence matrix features. Landscape metrics are used to investigate changes in landscape composition and configuration and to draw preliminary conclusions about environmental impacts. Speed and magnitude of urbanization is calculated by urbanization indices and the resulting impacts on the environment are quantified by ecosystem services. Growth of urban areas and urban green spaces occurred at the expense of cropland in both regions. Alongside a decrease in natural land cover, urban areas increased by approximately 120% in Shanghai, nearly ten times as much as in Stockholm, where the most significant land cover change was a 12% urban expansion that mostly replaced agricultural areas. From the landscape metrics results, it appears that fragmentation in both study regions occurred mainly due to the growth of high density built-up areas in previously more natural/agricultural environments, while the expansion of low density built-up areas was for the most part in conjunction with pre-existing patches. Urban growth resulted in ecosystem service value losses of approximately 445 million US dollars in Shanghai, mostly due to the decrease in natural coastal wetlands while in Stockholm the value of ecosystem services changed very little. Total urban growth in Shanghai was 1768 km2 and 100 km2 in Stockholm. The developed methodology is considered a straight-forward low-cost globally applicable approach to quantitatively and qualitatively evaluate urban growth patterns that could help to address spatial, economic and ecological questions in urban and regional planning.

    Sediment samples were taken in the water upstream, near and downstream of the outflow of a purification plant near Stockholm, Sweden. The waste plant receives, treats and deposits domestic and industry refuse and have earlier received latrine. An Otto Gravity Corer was used for sampling and the sediment was cut into centimetres slices, freeze-dried and analysed for the total content and isotopic composition of carbon and nitrogen using a CF-IRMS (Finnigan Delta plus). Freeze-dried sediment subsamples were digested in a microwave oven in the presence of nitric acid and hydrogen peroxide, and analysed for metals with ICP-OES (Varian Vista AX). This study shows that the sediments from the outflow of the waste plant have d15N values indicating denitrification and reworking by bacteria (δ15N values ranging from +16 to +19 ppm). Upstream of the outflow and 600 metres downstream, the δ15N are in a more natural range (+2 to +3 ppm respective +7 to +9 ppm). The δ13C values show that the material is of terrigenous origin. δ13C values in the outflow samples (-25 to -21 ppm), differ from the samples collected upstream (-25 to -23 ppm) and downstream the outflow (-27 to -25 ppm). Plotting δ13C against total carbon indicate that the downstream samples do not have the same main source as the other samples, which also can be seen in the 1/CTOT vs. δ13C. There is a general interest to find out more about the metal releases to the environment from this point source. In this investigation the sediment have been analysed for metals, as for example Cd, Cu, Pb, and Zn. The Cd content is low <0.4 ppb. At a sediment depth of 5 cm the Cu concentrations were 19 μg/g upstream the outflow, 23 μg/g at the outflow and 60 μg/g downstream the outflow, Pb; 6 μg/g, 8 μg/g, respective 50 μg/g and Zn; 58 μg/g, 93 μg/g and 175 μg/g respectively.

    2008-12-01

    This article reports a test of the hypothesis that municipalities within the County of Stockholm have varying incidence rates of type 1 diabetes (T1D), suggesting a strong etiologic environmental component to the disease. The study group included T1D patients in the age group from birth to 18 years who were diagnosed each year from 20 municipalities in Stockholm County during the 1990-2003. Specific incidence rates by age, sex, and socioeconomic characteristics (income level, proportion of taxpayers, proportion of foreigners, population density and green cover) were estimated annually together with age standardization. chi(2) analyses were used for the statistical assessment of variability in incidence. During the study period, 733 newly diagnosed T1D patients aged 0-18 years were recorded from the 20 municipalities under study. The overall age-standardized incidence in these 20 municipalities was 24.38 (22.65-26.21) per 100,000, with 45.35 (32.08-62.29) as highest and 13.41 (9.53-18.35) as lowest estimated incidence. For all socioeconomic variables statistically significant heterogeneity was demonstrated in the standardized incidence rate. High green index was positively associated with the incidence of T1D, as was low population density. For the three remaining socioeconomic variables no clear patterns of associations with incidence of T1D were seen. This study demonstrates a considerable and statistically significant variation between the lowest and highest values in the incidence and prevalence rates for T1D in municipalities of Stockholm County. Such variation seems unlikely to be explained by genetic differences since the population is homogeneous. Our study provides support for the hypothesis that environmental factors have a major influence on the pathogenesis of T1D.

    Hexachlorocyclohexane (HCH) isomers (α-, β- and γ- HCH [lindane]) were recently added to the list of persistent organic pollutants regulated by the Stockholm Convention, and therefore, the legacy of HCH and lindane production has become an issue of global relevance. The production of lindane with the much larger quantities of associated waste isomers has generated large waste deposits and contaminated sites. This article presents an overview of HCH-polluted sites in Brazil as a basis for further activities related to the Stockholm Convention. The locations of HCH stockpiles and contaminated sites in Brazil arising from production and formulation have been compiled and mapped. This shows that the measures taken over the past 25 years have not resulted in remediation of the HCH pollution. An exposure risk study has been summarised for one major site and is included to demonstrate the contemporary relevance of the contamination. Major site remediation efforts are planned at one site but people live close to several other sites, and there is an urgent need of further assessments and remediation to ensure the protection of human health and the environment. The Stockholm Convention requires a systematic approach and should be adopted for the assessment of all sites and appropriate isolation/remediation measures should be facilitated. The appropriate planning of these activities for the production site in Rio de Janeiro could be a positive contribution for Rio+20 highlighting that green economy and sustainable production also include the appropriate management of legacies of historic production of an industrial sector (here the organochlorine industry).

    More than a decade ago, the Stockholm Convention on Persistent Organic Pollutants (POPs), one of the multilateral environmental agreements administered by the United Nations Environment Programme (UNEP), entered into force. The objective of this Convention is to protect human health and the environment by controlling the releases of POPs. According to its Article 16, the effectiveness of the Stockholm Convention shall be evaluated using comparable monitoring data on the presence of POPs as well as their regional and global environmental transport. Here, we present a time series analysis on atmospheric POP concentrations from 15 monitoring stations in North America and Europe that provide long-term data and have started operations between 1990 and 2003. We systematically searched for temporal trends and significant structural changes in temporal trends that might result from the provisions of the Stockholm Convention. We find that such structural changes do occur, but they are related mostly to effects of national regulations enforced prior to the implementation of the Stockholm Convention, rather than to the enforcement of the provisions laid out in the Convention. One example is that concentrations of polychlorinated biphenyls, many of which started to decrease rapidly during the 1990s. Also effects of chemical transport and fate, for instance the re-volatilization of POPs from secondary sources, are thought to be a cause of some of the observed structural changes. We conclude that a decade of air monitoring data has not been sufficient for detecting general and statistically significant effects of the Stockholm Convention. Based on these lessons, we present recommendations for the future operation of existing monitoring programs and advocate for a stricter enforcement of the provisions of the Stockholm Convention, in the current absence of proof for its effectiveness.

    The Stockholm Cancer Prevention Program (SCPP) is among the first comprehensive community intervention programs in the world aimed at reducing cancer incidence and mortality. The program began in 1987 in an urban area with more than 1.6 million inhabitants. In its work, SCPP utilizes a community-based approach focusing on (1) reduction in tobacco consumption, (2) reduction in dietary fat consumption and increase in dietary fiber consumption, and (3) changing sunbathing behavior in order to reduce the incidence of malignant melanoma. The overall philosophy of the program is to initiate activities capable of affecting the life style of the Stockholm population in these directions. SCPP intends to influence behavior through individual face-to-face contact. The tool for this contact is collaboration with independent organizations which are already active in the target communities. Food supply to the general public will be influenced through food producers, wholesalers, retailers, and caterers. Tobacco use, food habits, and sunbathing habits will be influenced via occupational health services; public health services including primary care, schools and municipal social services; voluntary organizations; and mass media. A model for possible ways of evaluating the program has been designed. PMID:1782634

    The purpose of this study was to estimate the prevalence of anabolic androgenic steroid (AAS) use and offers to use among gym users in Stockholm County (Sweden), and to conduct a comparison of concordance in estimates of AAS and supplements at gyms between two data collection methods. A questionnaire was distributed to members at 36 training facilities and 1,752 gym users participated in the study. An observation study was conducted as covert participant observations at 64 gyms. According to the questionnaire, 3.9% of men reported life time use of AAS, 1.4% use during the past 12 months and 0.4% AAS use during past 30 days. Not only were there similar patterns found in the two methods, i.e., similar age and gender distributions for AAS use, but analyses of concordance showed that gyms with a higher prevalence of self-reported AAS-use and supplement use (questionnaire) showed a significantly higher proportion of observer-assessed AAS users. Analyses of individual predictors showed that AAS users were almost always young men, regular weight trainers and more often users of drugs and nutritional supplements. The higher prevalence of AAS use among gym users than in the general population makes the former an appropriate target group for AAS prevention. The connection between supplements, drugs and AAS use suggests that effective AAS prevention need to focus on several risk factors for AAS use. The clear resemblance in estimates between the observation and questionnaire data strengthen the credibility of the two methods.

    This report analyzes the evolution of energy use in Sweden since the early 1970s. The purpose of the study, which is sponsored by NUTEK, Department of Energy Efficiency, the Swedish Agency for Technical and Industrial Development, is to shed light on the future path of energy use in Sweden by quantifying and understanding changes in past energy use. Energy efficiency has been identified by Swedish authorities in countless official studies as a key element in Sweden`s efforts to restrain oil imports, reduce reliance on nuclear power, reduce environmental impacts of energy use, and reduce CO{sub 2} emissions. To understand the role or performance of energy efficiency in the 1970s and 1980s in Sweden, and what this performance means about the future, the authors seek answers to three broad questions: (1) How has the structure and efficiency of energy use in Sweden evolved since the early 1970s, and where data permit, since even earlier? What caused these changes? (2) How does the structure of energy use in Sweden differ from that of other countries, and how has the evolution of energy use in Sweden differed from developments in other countries? (3) How much energy has Sweden saved, and why? Are these savings permanent? To what extent were they offset by changes in the structure of energy use? And to what extent is the magnitude of these savings dependent upon the way we measure energy use? The report reviews the long-term evolution of Swedish energy use, focusing on developments in five sectors of the economy: residential, service, industrial (manufacturing and {open_quotes}other industry{close_quotes} defined as mining, agriculture, forestry and fisheries, and construction), travel, and freight. The authors then examine Swedish energy use in a broader perspective, drawing detailed comparisons to other nations. Finally, they discuss a series of issues that hover over the future of energy demand in Sweden.

    2009-04-01

    Local and regional-scale model calculations have been performed to estimate the effects of emissions in Stockholm on the population exposure to particulate matter (PM) within the city, in surrounding areas, and in the rest of Europe. The impacts of five different emission sources were investigated: Road traffic exhaust, split into Light Duty Vehicles (LDV) and Heavy Duty Vehicles (HDV), Sea Traffic, Power Plants and Residential Heating. The emissions from non-exhaust (mainly road wear due to use of studded tyres) were also treated, in addition to combustion sources. The calculated impact of the Stockholm emissions on atmospheric concentrations of particles were weighted by the population distribution and the calculated yearly average total European population exposures for the different sources are summarised below (unit: person μg/m3). Wear particles: Road Traffic 2 520 000 Directly emitted PM: LDV-exhaust 150 000, HDV-exhaust 55 000, Sea Traffic 17 000, Power Plants 87 000, Residential Heating 178 000 - 886 000 Secondarily formed inorganic particles (nitrate, sulphate, ammonium): LDV 315 000, HDV 117 000, Sea Traffic 70 000, Power Plants 193 000, Residential Heating 26 000 - 70 000 Non-exhaust (road wear) particles dominate the total impact on PM10 exposure, contributing about 60-70% to the total exposure, due to all the studied sources in Stockholm. The calculated population exposure to the wear particles is to a very large extent (87%) occurring within the Stockholm area. The uncertainties in the emission estimates for Residential Heating using biomass (wood) are very large but it seems to be an important PM source in Stockholm. Two different estimates of the emissions were used; in the lowest estimate, which seems more realistic, the contribution to population exposure of directly emitted combustion particles from residential heating is of similar magnitude (178 000 person μg/m3) as the contribution from road traffic exhaust (205 000 person μg/m3).

    This paper explores the contributions of the Cultural Formulation (CF) interview to an overall understanding of patients, and focuses on the narratives of 23 newly referred patients with migrant backgrounds seeking help at a psychiatric outpatient clinic in Stockholm. Through text content analysis methods we identified five themes: displacement in space and time; mental illness as a physical disability; life events as etiological factors; concealing as a coping strategy; and being lost in a fragmented health care system. Findings indicate the need to contextualize symptoms for an in-depth comprehension of patients' phenomenology. Both clinical and policy implications are discussed. The findings suggest that a section on migration and acculturation should be added to the cultural formulation in the next edition of DSM.

  10. How does lean work in emergency care? A case study of a lean-inspired intervention at the Astrid Lindgren Children's hospital, Stockholm, Sweden

    PubMed Central

    2012-01-01

    Background There is growing interest in applying lean thinking in healthcare, yet, there is still limited knowledge of how and why lean interventions succeed (or fail). To address this gap, this in-depth case study examines a lean-inspired intervention in a Swedish pediatric Accident and Emergency department. Methods We used a mixed methods explanatory single case study design. Hospital performance data were analyzed using analysis of variance (ANOVA) and statistical process control techniques to assess changes in performance one year before and two years after the intervention. We collected qualitative data through non-participant observations, semi-structured interviews, and internal documents to describe the process and content of the lean intervention. We then analyzed empirical findings using four theoretical lean principles (Spear and Bowen 1999) to understand how and why the intervention worked in its local context as well as to identify its strengths and weaknesses. Results Improvements in waiting and lead times (19-24%) were achieved and sustained in the two years following lean-inspired changes to employee roles, staffing and scheduling, communication and coordination, expertise, workspace layout, and problem solving. These changes resulted in improvement because they: (a) standardized work and reduced ambiguity, (b) connected people who were dependent on one another, (c) enhanced seamless, uninterrupted flow through the process, and (d) empowered staff to investigate problems and to develop countermeasures using a "scientific method". Contextual factors that may explain why not even greater improvement was achieved included: a mismatch between job tasks, licensing constraints, and competence; a perception of being monitored, and discomfort with inter-professional collaboration. Conclusions Drawing on Spear and Bowen's theoretical propositions, this study explains how a package of lean-like changes translated into better care process management. It adds new knowledge regarding how lean principles can be beneficially applied in healthcare and identifies changes to professional roles as a potential challenge when introducing lean thinking there. This knowledge may enable health care organizations and managers in other settings to configure their own lean program and to better understand the reasons behind lean's success (or failure).

    2016-02-01

    Babesiosis is an emerging tick-transmitted zoonosis in large parts of the world. In Sweden, the occurrence and diversity of Babesia species is largely unknown. In order to estimate the exposure to Babesia from infected ticks, we collected questing Ixodes ricinus from several sites across southern Sweden during two consecutive field seasons and investigated the occurrence of Babesia species. We report for the first time the occurrence of the zoonotic species Babesia venatorum in Swedish ticks, with a prevalence of 1%. We also detected B. microti (prevalence 3.2%) and B. divergens (prevalence 0.2%). The incidence of Babesia in questing ticks is substantially lower than that of several other tick-borne diseases in Sweden. Nevertheless, babesiosis should not be neglected as a possible diagnosis following tick bites in humans and animals in Sweden.

  15. Agency and capabilities to achieve a work-life balance: a comparison of Sweden and Hungary.

    2011-01-01

    This study develops a conceptual framework with a capabilities and agency approach for analyzing work–life balance (WLB) applied in two societies (Hungary and Sweden), which have different working time regimes, levels of precarious employment, and gender equality discourses and norms. Inspired by Amartya Sen, we present a model illustrating how agency freedom for WLB depends on multiple resources at the individual, work organizational, institutional, and normative/societal levels. Using a unique qualitative survey conducted in two cities, Budapest and Stockholm, we analyze how mothers and fathers subjectively experience the tensions between family and work demands, and their possibilities for alternative choices (agency freedom). We find similarities in these tensions involving time pressure and time poverty, cutting across gender and education. Our Hungarian parents, nevertheless, experience greater agency inequalities for WLB, which reflect weaker institutional resources (conversion factors) as well as cultural/societal norms that act as constraints for WLB claims in the workplace and household. Our study reveals that Swedish parents, both men and women, express a strong sense of entitlement to exercise rights to care. PMID:21966697

    It is a continual challenge trying to improve the quality of prescribing while concurrently trying to address increasing pharmaceutical development, utilization and expenditure. National and regional reforms and initiatives in Sweden have moderated growth in ambulatory drug expenditure to 2.7% per annum in recent years despite increasing volumes. National reforms include mandatory generic substitution and value-based pricing alongside devolution of drug budgets to the regions. Regional initiatives include strengthening the role of the regional Drug and Therapeutic Committees, further budget devolution as well as strategies incorporating prescribing guidance and monitoring coupled with financial incentives. The extent and nature of the regional initiatives vary depending on their characteristics. In this article, we compare initiatives undertaken in two major counties, Stockholm and Ostergötland, and their outcomes. Outcomes include annual drug budget savings while achieving agreed quality as well as increased adherence to prescribing targets and guidance; the latter associated with savings. Appraising these multifaceted reforms can provide guidance to other countries and regions in view of their diversity. Future steps must incorporate measures to improve the utilization of new expensive drugs, which should include horizon scanning and forecasting activities as well as post-launch activities involving monitoring of prescribing and registries. This may well require cooperation with other European countries.

    In this chapter, an introduction to ab initio molecular dynamics (AIMD) has been given. Many of the basic concepts, like the Hellman-Feynman forces, the difference between the Car-Parrinello molecular dynamics and AIMD, have been explained. Also a very versatile AIMD code, the CP2K, has been introduced. On the application, the emphasis was on the aqueous systems and chemical reactions. The biochemical applications have not been discussed in depth.

    In this study, we monitored the newly added Stockholm Convention persistent organic pollutants (POPs) HCHs, PeCBz, endosulfans, chlordecone, PBDEs, PBBs and PFCs in industrial, urban, and agricultural soils in South Korea, in order to evaluate their distributions and potential sources. These POPs were widely distributed throughout South Korea, and their concentrations and distributions were affected by land use, reflecting their sources. The overall concentrations of HCHs, PeCBz, endosulfans, PBDEs, and PFCs in soils were in the range of ND (non-detectable)-0.358 ng/g (average±standard deviation: 0.060±0.080 ng/g), ND-0.531 ng/g (0.083±0.133 ng/g), 0.058-8.42 ng/g (2.19±2.43 ng/g), 0.004-4.78 ng/g (0.68±1.06 ng/g), and ND-1.62 ng/g (0.50±0.46 ng/g), respectively. Agricultural soils showed the highest concentration of endosulfan, which was the most recently used pesticide monitored in this study. On the other hand, industrial soils contained the highest concentrations of PeCBz, PBDEs, and PFCs, which were mainly introduced to environment via the industrial activities. PMID:24476973

    The authors examine current trends in urban risks and resilience in relation to hazardous material transports in general, and crisis communication and the Stockholm liquefied petroleum gas (LPG) near miss in 1998 in particular. The article discusses how current dynamics affecting urban areas, such as the decay in terms of increased condensation and limited expansion alternatives combined with industry site contamination and transports of hazardous materials on old worn-out physical infrastructure, work together to produce high-risk factors and increase urban vulnerability in large parts of the world today. Crisis communication takes a particularly pronounced role in the article as challenges in communication and confidence maintenance under conditions of information uncertainty and limited information control are explored. The LPG near miss case illustrates a Swedish case of urban risk and the tight coupling to hazardous material transports. The case also serves as a current example of Swedish resilience and lack of preparedness in urban crises, with particular observations and lessons learned in regards to crisis communication.

    Surface soil contamination is a worldwide problem. Many regulatory jurisdictions attempt to control human exposures with regulatory guidance values (RGVs) that specify a soil's maximum allowable concentration. Pesticides are important soil contaminants because of their intentional toxicity and widespread surface soil application. Worldwide, at least 174 regulatory jurisdictions from 54 United Nations member states have published more than 19,400 pesticide RGVs for at least 739 chemically unique pesticides. This manuscript examines the variability of the guidance values that are applied worldwide to the original 2001 Stockholm Convention persistent organic pollutants (POP) pesticides (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene) for which at least 1667 RGVs have been promulgated. Results indicate that the spans of the RGVs applied to each of these pesticides vary from 6.1 orders of magnitude for Toxaphene to 10.0 orders of magnitude for Mirex. The distribution of values across these value spans resembles the distribution of lognormal random variables, but also contain non-random value clusters. Approximately 40% of all the POP RGVs fall within uncertainty bounds computed from the U.S. Environmental Protection Agency (USEPA) RGV cancer risk model. Another 22% of the values fall within uncertainty bounds computed from the USEPA's non-cancer risk model, but the cancer risk calculations yield the binding (lowest) value for all POP pesticides except Endrin. The results presented emphasize the continued need to rationalize the RGVs applied worldwide to important soil contaminants.

    2011-08-01

    Policy measures that reduce or replace road traffic can improve environmental conditions in most large cities. In Stockholm a congestion charge was introduced during a test period in 2006. This was a full-scale trial that proved to meet its targets by reducing traffic crossing the inner city segment during rush hours by 20%. Emissions of carbon dioxide and particles were also substantially reduced. This study, based on in-depth interviews with 40 inhabitants, analyses how and why new travel habits emerged. The results show that particular, sometimes unexpected, features of everyday life (habits, resources, opportunities, values, etc.) were crucial for adjustment of travel behaviour in relation to the policy instrument. One example was that those accustomed to mixing different modes of transport on a daily basis more easily adapted their travel in the targeted way. On a more general level, the results revealed that the policy measure could actually tip the scales for the individual towards trying out a new behaviour.

    The aim of the study was to optimize the criteria for the BRCA1 and BRCA2 gene testing and to improve oncogenetic counseling in the Stockholm region. Screening for inherited breast cancer genes is laborious and a majority of tested samples turn out to be negative. The frequencies of mutations in the BRCA1 and BRCA2 genes differ across populations. Between 1997 and 2000, 160 families with breast and/or ovarian cancer were counseled and screened for mutations in the two genes. Twenty-five BRCA1 and two BRCA2 disease-causing mutations were found. Various factors associated with the probability of finding a BRCA1 mutation in the families were estimated. Age of onset in different generations and other malignancies were also studied. Families from our region in which both breast and ovarian cancer occur were likely to carry a BRCA1 mutation (34%). In breast-only cancer families, mutations were found only in those with very early onset. All breast- only cancer families with a mutation had at least one case of onset before 36 years of age and a young median age of onset (<43 years). Other malignancies than breast and ovarian cancers did not segregate in the BRCA1 families and surveillance for other malignancies is not needed, in general. Decreasing age of onset with successive generations was common and must be taken into account when surveillance options are considered. PMID:11336395

    The setting of analytical quality specifications in laboratory medicine has been a topic of discussion and debate for over 50 years: 15 years ago, as the subject matured and a profusion of recommendations appeared, many of them from expert groups, it was realised by a number of leading professionals that there was a need for a global consensus on the setting of such specifications. The Stockholm Conference held in 1999 on "Strategies to set global analytical quality specifications in laboratory medicine" achieved this and advocated the ubiquitous application of a hierarchical structure of approaches. The hierarchy has five levels, namely: 1) evaluation of the effect of analytical performance on clinical outcomes in specific clinical settings; 2) evaluation of the effect of analytical performance on clinical decisions in general using a) data based on components of biological variation, or b) analysis of clinicians' opinions; 3) published professional recommendations from a) national and international expert bodies, or b) expert local groups or individuals; 4) performance goals set by a) regulatory bodies, or b) organisers of external quality assessment (EQA) schemes; and 5) goals based on the current state of the art as a) demonstrated by data from EQA or proficiency testing scheme, or b) found in current publications on methodology. This approach has been much used since its wide promulgation, but there have been ongoing criticisms and new developments. The time seems right for an objective reappraisal of recommended strategies to set analytical performance goals.

    Involving organizations is crucial when developing community intervention strategies aimed at dietary change. This case study describes the use of a food fair as a change agent. The aim of the food fair was to obtain commitment and build up a network in the community comprised of professionals in the fields of food production, food distribution and information. The fair was organized in 1989 and intended to disseminate knowledge and information about healthy foods and encourage food industries, test kitchens and also publishing companies to develop and present products in accordance with the dietary objectives of the Stockholm Cancer Prevention Programme (ie a simultaneous reduction of fat and an increase in fibre intake). The food fair consisted of exhibitions and conferences/seminars. Policy makers, journalists, people in the educational and health professions and those working with food were invited to participate. Nearly 60 companies and organizations made presentations at the exhibition and 1,000 professionals attended the conferences and seminars. In all, 6,400 people visited the fair. Seventy-eight trade journals and newspapers and three radio stations reported on the fair. The food fair was so well received that a second fair was arranged in 1991.

  6. Determination of semi-volatile and particle-associated polycyclic aromatic hydrocarbons in Stockholm air with emphasis on the highly carcinogenic dibenzopyrene isomers

    The concentrations of polycyclic aromatic hydrocarbons (PAHs) have been determined in the gaseous phase and in various particulate matter (PM) size fractions at different locations in and outside of Stockholm, Sweden, representative of street level, urban and rural background. The focus has been on the seldom determined but highly carcinogenic dibenzopyrene isomers (DBPs) dibenzo[a,l]pyrene, dibenzo[a,e]pyrene, dibenzo[a,i]pyrene and dibenzo[a,h]pyrene. PAHs with 3 rings were found to be mainly associated with the vapor phase (>90%) whereas PAHs with 5-6 rings were mostly associated with particulate matter (>92%) and the 4-ringed PAHs partitioned between the two phases. PAH abundance was determined to be in the order street level > urban background > rural background with the PM10 street level 2010 mean of benzo[a]pyrene (B[a]P) reaching 0.24 ng/m3, well below the EU annual limit value of 1 ng/m3. In addition, higher PAH concentrations were found in the sub-micron particle fraction (PM1) as compared to the super-micron fraction (PM1-10) with the abundance in PM1 varying between 57 and 86% of the total PAHs. The B[a]P equivalent concentrations derived for DB[a,l]P and total DBPs exceeded 1-2 and 2-4 times, respectively, that of B[a]P at the four sampling sites; therefore underestimation of the cancer risk posed by PAHs in air could be made if the DBPs were not considered in risk assessment using the toxic equivalency approach, whilst the high correlation (p < 0.001) found in the relative concentrations supports the use of B[a]P as a marker substance for assessment of the carcinogenic risk associated to PAHs. However, the big difference in concentration ratios of B[a]P and the DBPs between the present study and some literature data calls for further research to evaluate the temporal and spatial invariance of the B[a]P/DBP ratios.

  7. What's 'left' in the 'Garden of Sweden'?

    PubMed

    Olsen, Gregg M

    2013-01-01

    Liberalization, restructuring, and retrenchment have been underway in Sweden for more than two decades and have rapidly accelerated under the current non-socialist coalition government. It is uncertain how much of the Swedish social policy model is "left" now, in terms of both what remains of it and its political character. A cross-temporal look at developments within Sweden reveals striking and continual rollbacks and marketization since the 1990s. However, this view must be qualified, both because Sweden's undisputed descent is from a comparatively lofty position and because there have been some noteworthy, but often ignored, gains even amidst marked decline over the past few decades. A cross-national examination indicates that, despite rapidly rising rates of income and wealth inequality, Sweden remains an egalitarian leader in several respects. This view must be qualified, too, because, while it continues to routinely out-perform Anglo nations such as Canada, the United Kingdom, and the United States, Sweden is less often, and less notably, distinct from several of its continental counterparts in Europe now. Moreover, the foundation of the model, labor strength, has been significantly undermined.

    OBJECTIVES—Medical surveillance of workforces exposed to vibration has been recommended with the Stockholm workshop scales. The aims of this study were (a) to evaluate how the results of the objective tests individually and jointly associated with the final Stockholm workshop staging, (b) how this staging related to the history of exposure to vibration, and (c) how different trades were affected by the hazards from vibrating tools.
METHODS—All workers exposed to vibration in a heavy engineering company were examined with a questionnaire and a battery of tests. An assessment of staging by the Stockholm workshop scales was made. Estimates of the daily exposure and lifetime dosage of vibration of the various trades were reached.
RESULTS—The average years of tool use was 23.3 years (range 3-47 years) and the mean lifetime exposure was 11 022 (range 1012-46 125) hours. The individual neurological tests were all strongly associated with the Stockholm neurological staging but the cold provocation test was not associated with the Stockholm vascular staging. Neurological staging was significantly associated with age, years of tool use, and total hours of exposure to vibration, but not with trade or smoking. Vascular staging was significantly associated with age, years of tool use, total hours of exposure to vibration, and trade, but not with smoking. The mean neurological latent period was 19.7 (range 2-40) years and for the vascular component 19.1 (range 2-40) years. These means varied significantly by trade. The overall prevalence of neurological findings of 62% was greater than the overall prevalence of vascular findings, which was 33%.
CONCLUSIONS—(1) The neurological objective tests were found to be of use in neurological staging. The cold provocation test was not associated with the vascular staging and therefore was of little value. (2) Years of tool use was the exposure variable most significantly associated with evidence of damage to neurological

    Cowpox virus, which has been used to protect humans against smallpox but may cause severe disease in immunocompromised persons, has reemerged in humans, domestic cats, and other animal species in Europe. Orthopoxvirus (OPV) DNA was detected in tissues (lung, kidney, spleen) in 24 (9%) of 263 free-ranging Eurasian lynx (Lynx lynx) from Sweden. Thymidine kinase gene amplicon sequences (339 bp) from 21 lynx were all identical to those from cowpox virus isolated from a person in Norway and phylogenetically closer to monkeypox virus than to vaccinia virus and isolates from 2 persons with cowpox virus in Sweden. Prevalence was higher among animals from regions with dense, rather than rural, human populations. Lynx are probably exposed to OPV through predation on small mammal reservoir species. We conclude that OPV is widely distributed in Sweden and may represent a threat to humans. Further studies are needed to verify whether this lynx OPV is cowpox virus.

  1. Radiocarbon apportionment of fossil versus biofuel combustion sources of polycyclic aromatic hydrocarbons in the Stockholm metropolitan area.

    2004-10-15

    Source-diagnostic markers and the isotopic composition of polycyclic aromatic hydrocarbons (PAHs) were examined in surface sediments from the greater Stockholm waterways to deduce the contribution from biomass sources to the environmental PAH load. The summed concentration of 20 PAHs ranged from 0.8 to 45.1 microg/g (dry weight) and exhibited a steep decline with increasing distance from the city center evidencing that sources within the metropolitan area of Stockholm dominate its PAH burden. Several diagnostic PAH ratios indicated an overwhelming predominance of pyrogenic sources over the petrogenic ones, while retene and 1,7-dimethylphenanthrene were unable to correctly evaluate the contribution from biomass combustion. The stable carbon isotope composition (delta13C) of individual PAHs ranged from -24.8 to -27.0% but also was proved inefficient to discriminate between different types of fuels due to the overlapping signals in various sources. The delta14C values of PAHs ranged between -550.4 and -934.1%, indicating a clear predominance of fossil fuel sources. By using an isotopic mass balance approach, we estimated that on average 17+/-9% of PAHs derived from biomass combustion. This radiocarbon apportionment, in conjunction with detailed energy statistics for the Stockholm region, revealed that the ambient PAH burden is roughly similar, per unit energy produced, from fossil fuels and biofuels. Societies' shifting energy policies toward a larger reliance on biofuels may thus not lead to further deterioration of air quality and respiratory ailments for the urban population. PMID:15543735

    Melting of the Weichselian ice sheet at ≈10 000 BP is inferred to have induced large to great intraplate earthquakes in northern Fennoscandia. Over a dozen large so-called postglacial faults (PGF) have been found, mainly using aerial photogrammetry, trenching, and recognition of numerous paleolandslides in the vicinity of the faults (e.g. Lagerbäck & Sundh 2008). Recent LiDAR-based mapping led to the extension of known PGFs, the discovery of new segments of existing PGFs, and a number of new suspected PGFs (Smith et al. 2014; Mikko et al. 2015). The PGFs in Fennoscandia occur within 14-25°E and 61-69°N; the majority are within Swedish territory. PGFs generally are prominent features, up to 155 km in length and 30 m maximum surface offset. The most intense microseismic activity in Sweden occurs near PGFs. The seismogenic zone of the longest known PGF (Pärvie fault zone, PFZ) extends to ≈40 km depth. From fault geometry and earthquake scaling relations, the paleomagnitude of PFZ is estimated to 8.0±0.3 (Lindblom et al. 2015). The new high-resolution LiDAR-derived elevation model of Sweden offers an unprecedented opportunity to constrain the surface geometry of the PGFs. The objective is to reach more detailed knowledge of the surface offset across their scarps. This distribution provides a one-dimensional view of the slip distribution during the inferred paleorupture. The second objective is to analyze the pattern of vertical displacement of the hanging wall, to obtain a two-dimensional view of the displaced area that is linked to the fault geometry at depth. The anticipated results will further constrain the paleomagnitude of PGFs and will be incorporated into future modeling efforts to investigate the nature of PGFs. ReferencesLagerbäck & Sundh 2008.

    Background and purpose The number of national arthroplasty registries is increasing. However, the methods of registration, classification, and analysis often differ. Methods We combined data from 3 Nordic knee arthroplasty registers, comparing demographics, methods, and overall results. Primary arthroplasties during the period 1997–2007 were included. Each register produced a dataset of predefined variables, after which the data were combined and descriptive and survival statistics produced. Results The incidence of knee arthroplasty increased in all 3 countries, but most in Denmark. Norway had the lowest number of procedures per hospital—less than half that of Sweden and Denmark. The preference for implant brands varied and only 3 total brands and 1 unicompartmental brand were common in all 3 countries. Use of patellar button for total knee arthroplasty was popular in Denmark (76%) but not in Norway (11%) or Sweden (14%). Uncemented or hybrid fixation of components was also more frequent in Denmark (22%) than in Norway (14%) and Sweden (2%). After total knee arthroplasty for osteoarthritis, the cumulative revision rate (CRR) was lowest in Sweden, with Denmark and Norway having a relative risk (RR) of 1.4 (95% CI: 1.3–1.6) and 1.6 (CI: 1.4–1.7) times higher. The result was similar when only including brands used in more than 200 cases in all 3 countries (AGC, Duracon, and NexGen). After unicompartmental arthroplasty for osteoarthritis, the CRR for all models was also lowest in Sweden, with Denmark and Norway having RRs of 1.7 (CI: 1.4–2.0) and 1.5 (CI: 1.3–1.8), respectively. When only the Oxford implant was analyzed, however, the CRRs were similar and the RRs were 1.2 (CI: 0.9–1.7) and 1.3 (CI: 1.0–1.7). Interpretation We found considerable differences between the 3 countries, with Sweden having a lower revision rate than Denmark and Norway. Further classification and standardization work is needed to permit more elaborate studies. PMID:20180723

    Due to the widespread use of agricultural and residential pesticides, the potential for pesticide soil contamination is a worldwide concern. In response, regulatory jurisdictions in at least 54 nations have promulgated guidance values to specify the maximum allowable concentration of pesticides in soils. Guidance values may be found for more than 700 pesticides. A previous analysis examined the values applied to the original "dirty dozen" persistent organic pollutant (POP) pesticides that were addressed in the 2001 Stockholm Convention (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene). Results are presented here for the "new POP" pesticides that were added to the Stockholm Convention in 2009 and 2011 (isomers of Hexachlorocyclohexane, Chlordecone, and isomers of Endosulfan). The guidance value extremes used worldwide for these pesticides vary by as much as 8.5 orders of magnitude and the randomness in their distributions resembles that of lognormal random variables. However, there are nonrandom value clusters in some distributions that may identify values around which consensuses are forming. The current value distributions imply that a wide range of human health risks are being accepted. Hopefully, the results presented will help regulatory jurisdictions and the regulated communities identify values that should be revised to be adequately protective of human health.

    Several significant developmental and socialisation processes in the life of children and adolescents take place in the area where they live. The extent to which they can feel and be safe in this environment is an important component of the success of those processes. This study highlights the independent contribution of neighbourhood and individual-level demographic and socioeconomic attributes to child and adolescent injuries. All individuals between the ages of 7 and 16 years living in Stockholm County in January 1998 (n=184 545) were followed up for their injuries during a five-year period considering injuries sustained as a pedestrian/cyclist/motor-vehicle rider and intentional injuries (violence-related and self-inflicted). A series of two-level logistic regressions were conducted to examine the association between the occurrence of injuries and individual (compositional) characteristics nested into parish of residence as well as contextual characteristics. For children and adolescents living in Stockholm County, contextual socioeconomic and social attributes of their place of residence were significant for injuries sustained as motor-vehicle riders but not for those sustained as pedestrians/cyclists or those inflicted intentionally. In the latter case, only the highest concentration of social benefit recipients was associated with significantly higher odds ratios. This emphasises that each injury mechanism has its own socioeconomic and social pathway, where contextual and compositional factors come into play to varying degrees.

    The aim was to develop and validate a standardized questionnaire - the Stockholm Indoor Environment Questionnaire (SIEQ). The validation procedure was based on sociological principles and test procedures for validation. The indicators of indoor environment are air quality, thermal climate, noise, and illumination. The indicators of health are symptoms comprised in the sick building syndrome (SBS). The questionnaire also contains questions about the apartment, individual behavior, and personal factors. The everyday language describing the building and its function was first obtained by qualitative personal interviews, then by standardized questions. The interview questionnaire was transformed into a postal self-administered questionnaire. The reduction of the questionnaire was based on correlation analysis. It was found that to obtain a good validity, general questions are not sufficient, but specific question on perceptions and observations are needed. Good test-retest agreement was found both on an area level, building level, and individually. For each indicator, a set of questions are constructed and validated. SIEQ has been used in several studies, and the results are presented in graphic problem profiles. Reference data has been calculated for the Stockholm area.

    Objectives The objective of this study was to analyse how hospitalisation after the age of 60 affected individuals' health-related quality of life (HRQoL). The main hypothesis was that a hospital admission in old age can be seen as a proxy of ill health and possibly as a health divider, separating life into a healthy and an unhealthy part. The extent to which this is true depends on which disease individuals face and how functional ability and HRQoL are affected. Settings This was a longitudinal study, based on an older cohort of individuals who participated in the Stockholm Public Health Cohort (SPHC) survey in 2006; the survey took place in Stockholm, Sweden. Information regarding hospitalisations and deaths, which is available through Swedish administrative registers, was linked to the survey from the National Patient Register and Cause of Death Register. Participants 2101 individuals, 65+ years old at inclusion, with no previous hospitalisations at baseline (2006), were followed for 4 years until 2010 (end of follow-up). Primary and secondary outcome measures HRQoL was assessed through a utility index derived from the EuroQol 5D questionnaire, at baseline and at 2010. The change in HRQoL after admission(s) to the hospital was estimated as the difference between the 2010 and 2006 levels using linear regression, also considering several covariates. Results A single hospitalisation did not reduce individuals' HRQoL, either for men or women. On the other hand, multiple any-cause hospitalisations reduced HRQoL between 3.2% and 6.5%. When looking into hospitalisations for specific causes, such as hip fractures, a decrease in HRQoL was observed as well; however, conclusions regarding this were impeded by the small sample size. Conclusions Hospital admissions in old age may indicate a shift from a healthy life to a life of compromised health when considering their frequency and cause over a period of time. PMID:27401358

  10. Ab interno trabeculectomy.

    2010-10-01

    Anterior chamber drainage angle surgery, namely trabeculotomy and goniotomy, has been commonly utilized in children for many years. Its' reported success has ranged between 68% and 100% in infants and young children with congenital glaucoma. However, the long-term success of these procedures has been limited in adults presumably due to the formation of anterior synechiae (AS) in the postoperative phase. Recently, ab interno trabeculectomy with the Trabectome™ has emerged as a novel surgical approach to effectively and selectively remove and ablate the trabecular meshwork and the inner wall of the Schlemm's canal in an attempt to avoid AS formation or other forms of wound healing with resultant closure of the cleft. This procedure seems to have an appealing safety profile with respect to early hypotony or infection if compared to trabeculectomy or glaucoma drainage device implantation. This might be advantageous in some of the impoverish regions of the Middle East and Africa where patients experience difficulties keeping up with their postoperative visits. It is important to note that no randomized trial comparing the Trabectome to other glaucoma procedures appears to have been published to date. Trabectome surgery is not a panacea, however, and it is associated with early postoperative intraocular pressure spikes that may require additional glaucoma surgery as well as a high incidence of hyphema. Reported results show that postoperative intraocular pressure (IOP) remains, at best, in the mid-teen range making it undesirable in patients with low-target IOP goals. A major advantage of Trabectome surgery is that it does not preclude further glaucoma surgery involving the conjunctiva, such as a trabeculectomy or drainage device implantation. As prospective randomized long-term clinical data become available, we will be better positioned to elucidate the exact role of this technique in the glaucoma surgical armamentarium. PMID:21180426

    The cancer incidence was studied in 18,030 patients (33% males, 67% females) with skin hemangioma who were admitted to Radiumhemmet, Karolinska Hospital, Stockholm, Sweden, 1920-1959. Radium-226 sources were used in 12,821 patients, x-ray therapy was used in 2,515 patients, and no radiotherapy was given to 2,694 patients. Cancer incidence in the cohort was searched by record linkage with the Swedish Cancer Register for the period 1958-1982. The median age was 6 months for the treated patients and 8 months for the patients not receiving radiotherapy. In the group treated with radium-226 or orthovoltage x rays (greater than or equal to 100-kV peak), 224 cancers were observed (relative risk (RR) = 1.18; 95% confidence interval (CI) = 1.03-1.35). In patients given contact x rays, 10 cancers were observed (RR = 0.71; 95% CI = 0.34-1.30). In patients not treated with ionizing radiation, 34 cancers were observed (RR = 0.93; 95% CI = 0.64-1.29). In patients treated with radium-226 or orthovoltage x rays, an RR of 1.65 was observed for breast cancer (95% CI = 1.26-2.13) and an RR of 2.73 was found for soft tissue tumors (95% CI = 1.18-5.38). Patients with brain tumors, thyroid cancers, and bone tumors had received radiotherapy close to the tumor site more often than expected. For patients with breast cancer, no such difference was found. For cancers of the breast and thyroid, the RR was higher in patients given more than one treatment.

    Three space flight experiments have been conducted to test and demonstrate the use of a passively controlled, materially closed, bioregenerative life support system in space. The Autonomous Biological System (ABS) provides an experimental environment for long term growth and breeding of aquatic plants and animals. The ABS is completely materially closed, isolated from human life support systems and cabin atmosphere contaminants, and requires little need for astronaut intervention. Testing of the ABS marked several firsts: the first aquatic angiosperms to be grown in space; the first higher organisms (aquatic invertebrate animals) to complete their life cycles in space; the first completely bioregenerative life support system in space; and, among the first gravitational ecology experiments. As an introduction this paper describes the ABS, its flight performance, advantages and disadvantages.

    Children with cystic fibrosis (CF) diagnosed by neonatal screening have a better nutritional development and other advantages compared with those in a nonscreened group. The two-tier immunoreactive trypsinogen (IRT)/DNA screening protocol has been found superior to the single-tier IRT approach, improving the positive predictive value and thus reducing the false-positive rate. However, variations of the DNA test are required for different populations. In this study we examined CFTR (cystic fibrosis transmembrane conductance regulator) mutations in 331 CF patients attending the centres in Stockholm, Lund and Uppsala, comprising about 75% of the CF population in Sweden. The frequency of deltaF508 among CF alleles was 68.3%. There were two other mutations, 394delTT and 3659delC, found to be fairly frequent, amounting to 8.5 and 7.9%, respectively. Other mutations were comparatively rare. A simple and effective method of analysing the three mutations from Guthrie cards has been developed. Assuming Hardy-Weinberg equilibrium, 90% of our CF patients will be expected to carry at least one deltaF508 allele and 97.6% to carry at least one deltaF508, 394delTT or 3659delC copy. Including the latter two in a screening programme would thus substantially reduce the risk of a false-negative outcome.

    Introduction Danish and Norwegian immigrant women in Sweden have an increased risk of cervical cancer compared to Swedish-born women. In addition, Danish and Norwegian immigrant women follow the national recommendations for attendance at cervical screening to much lesser extent than Swedish-born women. The aim of this study was to explore how Danish and Norwegian immigrant women in Sweden reason about attending cervical screening, focusing on women’s perceptions as to why they and their compatriots do not attend. Methods Eight focus group discussions (FGDs) were conducted with Danish and Norwegian immigrant women living in Stockholm. The women were between 26 and 66 years of age at the time of the FGDs, and were aged between <1 and 48 years old when they immigrated to Sweden. A FGD guide was used, which included questions related to cervical screening, and obstacles and motivators to attend cervical screening. The FGDs were tape recorded and transcribed, and the results analysed according to the principles of qualitative content analysis. Results The main theme was “Women have a comprehensive rationale for postponing cervical screening, yet do not view themselves as non-attenders”. Investigation of women’s rationale for non-attendance after being invited to cervical screening revealed some complex reasons related to immigration itself, including competing needs, organisational and structural factors and differences in mentality, but also reasons stemming from other factors. Postponing attendance at cervical screening was the category that linked all these factors as the reasons to why women did not attend to cervical screening according to the recommendations of the authorities. Conclusions The rationale used to postpone cervical screening, in combination with the fact that women do not consider themselves to be non-attenders, indicates that they have not actively taken a stance against cervical screening, and reveals an opportunity to motivate these women

    The Swedish National Registry for Tonsil Surgery has been operational since 1997. All ENT clinics in Sweden are encouraged to submit data for all patients scheduled for tonsil surgery. Preoperatively, age, gender and indication are recorded. Postoperatively, method (tonsillectomy or tonsillotomy), technique, and perioperative complications are recorded. Postoperative bleedings, pain, infections, and symptom relief are assessed through questionnaires. An earlier report from this registry showed that tonsillotomy had become more common than tonsillectomy in children with tonsil-related upper airway obstruction. The aim of this study was to categorize which instruments were used for tonsillotomy in Sweden and to compare their outcome and complication rate. All children 2-18 years, reported to the registry from March 2009 until September 2012, who underwent tonsillotomy on the indication upper airway obstruction, were included in the study. 1,676 patients were identified. In 1,602 cases (96%), a radiofrequency instrument was used. The postoperative bleeding rate was low (1.2%) and the degree of symptom relief was high (95.1%). Three different radiofrequency instruments (ArthroCare Coblation(®), Ellman Surgitron(®), and Sutter CURIS(®)) were used in 96% of the patients. There were no significant differences in the number of postoperative bleedings, postoperative infections or symptom relief between the instruments. The only difference found was in the number of days on analgesics, where more days were registered after use of Coblation(®). In Sweden, radiofrequency tonsillotomy is the dominant surgical technique used for tonsil hypertrophy causing upper airway obstruction in children. There are no significant differences in outcome between the different radiofrequency instruments except for number of days on analgesics after surgery.

    Progress towards gender equality involves changes in the traditional parental division - female caring and male breadwinning. One aspect is increased parental leave for fathers, which may benefit the health of mothers, children, and fathers themselves. We examined how social and health characteristics (2002) were associated with paternity leave in excess of the 'father quota' of 60 days (2003-2006) in the Stockholm Public Health Cohort. Generally, fathers with stable social position, fit lifestyles, and good health had increased chances of paternity leave uptake. Our findings may contribute to identifying target groups for parental leave strategies among fathers; they indicate also that research on gender equality and public health must carefully address the problems of confounding and health-related selection.

    The aim of this qualitative study was to explore and describe the perceptions of physical activity held by older urban Swedish and Irish adults. Qualitative interviews were carried out with 30 people age 65 years and older (mean age 74.5), of whom 15 were living in Dublin and 15 were living in Stockholm. The "thematic framework" approach was used to analyze the data. Three central themes were identified regarding people's perceptions of physical activity: physical activity as self-expression, physical activity as interaction, and physical activity as health promotion. Participants' perceptions of physical activity tended to relate to their perceived level of physical activity, regardless of their cultural background. Certain culture-specific motivators and barriers to exercise were also identified. Less active Irish men were more likely to underestimate the health-promoting benefits of exercise.

    This article reviews how epidemiological measures can be used in health planning. Theoretical considerations are discussed together with empirical data from Sweden. Formulation of targets, priority settings, resource allocation and monitoring systems are some ways in which epidemiological data can improve health planning. One important lesson for planning is that problems related to health, inequalities in health, and access to care, must be made visible to politicians, health personnel and the public. Further, there is a need to complement a national health policy with a decentralized planning system that takes local conditions and needs into consideration.

    OBJECTIVES—To find and investigate, retrospectively, as many cases as possible of Creutzfeldt-Jakob disease (CJD) in Sweden dying during the period 1 January 1985 to 31 December 1996 and to detect any possible case(s) of new variant CJD.
METHODS—The patients were found through computer search of all death certificates in Sweden on which CJD was mentioned, through information from the Swedish neuropathologists, and spontaneous reports from Swedish doctors and hospitals. Data concerning the patients were then collected from patients' case records and from brain histopathology reports.
RESULTS—In total 72 cases of spongiform encephalopathy were confirmed as definite by neuropathology, one of them with Gerstmann-Stäussler-Scheinker disease. In 51 further cases there were no brain pathology data but the diagnosis "probable" (37 patients) or "possible" (14 patients) CJD according to WHO criteria could be made on clinical grounds. There was a variation in number of deaths/year, from a minimum of five (1985) to a maximum of 16 (1990). Sixty patients died during the period 1985-90 and 62 during 1991-6. The sex ratio was nearly 1:1. Calculated for a population of 8.6 million (mean of 12 years) in Sweden this gives 1.18/million/year. Age at the time of the presenting symptoms ranged from 34 to 84 years. Only one patient was under 40 at the onset of symptoms. He had a spongiform encephalopathy but prion protein staining was negative. The duration of symptoms that could be attributed to CJD was 6 months or less in 75 cases, 7-12 months in 16 cases, 1 to 2 years in 15 cases, and more than 2 years in 16 patients. By definition all patients were demented. Other more common symptoms and signs were aphasia, dysphasia, dysathria, ataxia, myoclonus, pareses of the extremities, rigidity or spasticity, different types of hyperkinesias, and other psychiatric symptoms (depression, anxiety, and aggressiveness). Less common symptoms were hallucinations (mainly visual), visual

    Introduction The difference in breast cancer incidence and prognosis between ethnic groups seeks an explanation. We have recently shown that Swedish women are two to three times more likely to be diagnosed with breast cancer compared with Singaporean women. In the present paper, we compare breast cancer survival in the two countries. Methods We compared the survival of 10,287 Singaporean women and 17,090 Swedish women with breast cancer. Relative survival ratios were used to describe the prognosis in the two populations. A Poisson regression model was used to calculate relative risks for different follow-up periods, age groups, time of diagnosis and disease stages. Results The majority of the Swedish women had local cancer (80%) compared with Singaporean women (51%). The overall 5-year relative survival of the Swedish women appeared better (80%) than that of the Singaporean women (70%). A similar survival pattern was observed, however, between the two countries in a stage-by-stage comparison. Survival improved for all women in Singapore over the two decades, but only in the premenopausal women in Stockholm. In 1980 to 1989, premenopausal Singaporean women had 27% increased risk of death compared with Swedish women, adjusted for stage and year of follow-up, while the postmenopausal women had 48% increased risk. In 1990 to 1999, this risk decreased by 19% and 22% for the premenopausal and postmenopausal Singaporean women compared with the Swedish women. Conclusions The stage-dependent prognosis was similar for Singaporean women and for Swedish women. Singaporean women, both premenopausal and postmenopausal, had pronounced improvement in prognosis over the calendar periods, probably contributed by marked economic improvement, leading to better medical facilities and management with increased awareness of patients to diagnosis and treatment, as well as improved treatment options. Improvement seen only in the premenopausal women in Stockholm was probably due to improved

    The Stockholm Convention on Persistent Organic Pollutants (POPs) aims to protect human health and the environment from POPs through a range of measures aimed at reducing and ultimately eliminating their releases into the environment and subsequent human exposure. Article 16 of the Convention sets the basis for a mechanism to assess the success of the activities undertaken worldwide to implement the Convention. One of major pillars for the evaluation of the effectiveness of the Convention is monitoring data obtained through the Global Monitoring Plan (GMP) for POPs. The implementation of the GMP over the last eleven years, since the entry into force of the Convention, shows how a global treaty such as the Stockholm Convention streamlined existing monitoring efforts and triggered harmonization and further development of a global monitoring network. In its initial stages, long term POPs monitoring programmes were available only in some parts of the globe. Over more than a decade of generation of harmonized, comparable monitoring data on 23 chemicals of global concern, a rich and extremely valuable dataset has been generated in the frame of the GMP. Long-term monitoring programmes have enlarged the scope of their activities to cover newly listed chemicals, and new programmes have emerged. Monitoring data are broadly shared through the GMP data warehouse, the Convention's clearing-house mechanism, and through other appropriate global tools. Through its global reach, the GMP contributes to the global chemicals and waste policy agenda, supports and triggers further research initiatives, and provides information to the general public at large.

    Combustion-derived soot or black carbon (BC) in the atmosphere has a strong influence on both climate and human health. In order to propose effective mitigation strategies for BC emissions it is of importance to investigate geographical distributions and seasonal variations of BC emission sources. Here, a radiocarbon methodology is used to distinguish between fossil fuel and biomass burning sources of soot carbon (SC). SC is isolated for subsequent off-line 14C quantification with the chemothermal oxidation method at 375 °C (CTO-375 method), which reflects a recalcitrant portion of the BC continuum known to minimize inadvertent inclusion of any non-pyrogenic organic matter. Monitored wind directions largely excluded impact from the Stockholm metropolitan region at the EMEP-Aspvreten rural station 70 km to the south-west. Nevertheless, the Stockholm city and the rural stations yielded similar relative source contributions with fraction biomass ( fbiomass) for fall and winter periods in the range of one-third to half. Large temporal variations in 14C-based source apportionment was noted for both the 6 week fall and the 4 month winter observations. The fbiomass appeared to be related to the SC concentration suggesting that periods of elevated BC levels may be caused by increased wood fuel combustion. These results for the largest metropolitan area in Scandinavia combine with other recent 14C-based studies of combustion-derived aerosol fractions to suggest that biofuel combustion is contributing a large portion of the BC load to the northern European atmosphere.

    The load of various hydrophobic organic compounds (HOCs) on the Baltic Sea aquatic environment is considerable. This investigation samples the water area around Stockholm, of special concern since it is one of the most densely populated urban areas in the Baltic region. Stockholm also houses several power plants, municipal waste incinerators, waste water treatment plants, ports and oil terminals. The runoff from a large lake also passes through the estuarine-like archipelago of Stockholm. Due to the high particulate-water partition coefficients (K[sub p]) of most ecotoxicologically relevant HOCs, particulate matter (PM) becomes very important for occurrence and distribution in the aquatic environment. This PM is the basic food source for important organisms in the benthic, pelagic and littoral parts of the aquatic ecosystem. The load of various HOCs such as petrogenic hydrocarbons (PHCs), various polynuclear aromatic compounds (PACs), and chlorinated hydrocarbons such as polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in association with PM in the aquatic environment of the Stockholm area is well documented. However, the ecotoxicological relevance of organic extracts of PM, including the above identified compounds and various unidentified HOCs, is not fully evaluated. To evaluate the genotoxic potential of extracts of PM, collected with sediment traps in the Stockholm water area and in the open northern Baltic, we used the Ames test on Salmonella typhimurium strain TA100, with and without a metabolizing system. After extraction and before the mutagenicity tests all PM samples were fractionated on an HPLC-system into three fractions containing aliphatic/monoaromatic-, diaromatic, (containing, e.g., PCDD/Fs and PCBs) and polyaromatic compounds (containing various PACs). The relative mutagenic potential of these fractions at the different sediment trap sampling stations are discussed and evaluated. 13 refs., 1 tab.

    Countries such as Sweden that have a low prevalence of methicillin-resistant Staphylococcus aureus (MRSA) offer the opportunity to discern and study transmission of imported cases of MRSA. We analyzed 444 imported cases of MRSA acquisition reported in Sweden during 2000–2003. Risk for MRSA in returning travelers ranged from 0.1 (95% confidence interval [CI] 0.01–0.4) per 1 million travelers to Nordic countries to 59.4 (95% CI 44.5–79.3) per 1 million travelers to North Africa and the Middle East. Most imported cases (246, 55%) were healthcare acquired, but regions with the highest risk for MRSA in travelers showed a correlation with community acquisition (r = 0.81, p = 0.001). Characteristic differences in MRSA strains acquired were dependent on the region from which they originated and whether they were community or healthcare acquired. Knowledge of differences in transmission of MRSA may improve control measures against imported cases. PMID:20113546

    This study examined all unintentional firearm fatalities while hunting that occurred in Sweden between 1983 through 2008. The circumstances as well as the impact of the hunter's exam on fatality frequency were analysed. During these 26 years, there were 48 such fatalities, representing 53% of all (n=90) unintentional firearm deaths during the same period. The average annual number of fatalities decreased over the last few decades. Very restrictive firearm legislation in Sweden combined with the introduction of a mandatory hunter's exam since 1985 accounted, at least partly, for this finding. Moose hunting accounted for 46% of the fatalities and small game hunting for the remaining cases. The mean age of the victims was 50 years and 96% of them were males; all shooters were males. During moose hunting, most of the victims were mistaken for game, whereas in small game hunting most of the fatalities were related to falls and improper handling of the weapon. Human error was thus the main cause of these fatalities. PMID:21908112

  10. Malthus and neo-Malthusianism in Sweden.

    PubMed

    Kalvemark, A S

    1980-01-01

    Focus in this discussion is on Malthus and neo-Malthusianism in Sweden. Neo-Malthusianism arrived in Sweden at the beginning of the 1880s when Knut Wicksell gave a public lecture at a youth meeting of a temperance society in Uppsala. The lecture resulted in public scandal and made neo-Malthusian ideas known overnight in Sweden. Wicksell maintained that poverty was the primary cause of most evils in society, and it was caused by the pressure from population increase on the means of subsistence. In his lecture he referred to Malthus explicitly and gave a summary of the Malthusian principle of population on which he based his reasoning. At the time he only knew of Malthus' ideas indirectly by reading George Drysdale's book, "The Elements of Social Science." The questions that arise are whether Malthus' ideas were only indirectly studied and whether neo-Malthusiansim was just seen as an equivalent of birth control and contraceptives, the very means of preventive checks for population growth that Malthus condemned for moral reasons. Wicksell focused on the causes and consequences of emigration in a lecture in 1881. He again saw rapid population growth as the cause of poverty, which in turn caused emigration. The rapid rise in Swedish emigration in the 1880s created considerable interest. Generally, the common view at the time was that Sweden suffered from a certain population pressure and corresponding underemployment. Johan Leffler, a young economist, had a different opinion. He saw the problem in an outspoken Malthusian way, suggesting that under the prevailing overpopulation in Sweden emigration could not be harmful. At the turn of the centruy Gustav Sundbarg was among those describing emigration as a deadly threat to Swedish society. Sundbarg not only turned against Malthus, but he also condemned neo-Malthusianism for moral reasons. Sundbarg maintained that demographic and economic development over the 19th century did not verify Malthus' assumption that population

    Several studies have reported poorer infant outcome among immigrants, but contrary evidence also exists. Between 1940 and 1999 more than a half million Finns emigrated to Sweden, which made Finns the largest minority group in Sweden. Our aim was to investigate fertility trends, parturients' background and pregnancy outcomes among Finns in Sweden, and to compare the findings with those obtained among Swedes in Sweden and Finns in Finland. The data came from the Finnish and Swedish Medical Birth Registers for the years 1987-1998. All deliveries by women born in Finland and having given birth in Sweden (N=33874) were compared with a 10% sample of all deliveries by Swedish parturients in Sweden (N=108549) and of all Finnish deliveries (n=75133). Among Finns in Sweden, the number of live births per 1000 women aged 15-49 years declined significantly in the late 1990s. The change in the total fertility rate was less dramatic: the rate for Finns in Sweden followed the total Swedish rate although it remained from 5% to 10% higher up to the mid-1990s. Finns who had given birth in Sweden were older, had a higher parity and a higher prevalence of previous miscarriages, and smoked more often than did Swedes in Sweden or Finns in Finland. The crude infant outcomes of Finns having given birth in Sweden were equal to those among Swedes in Sweden (except for the incidence of small for gestational age), but poorer than in Finland. Biological factors explained the differences between Finns in Sweden and Finland in being small for gestational age, and biological factors and smoking explained the difference in prematurity. The difference in low birth weight remained statistically significant (3.9% versus 3.6% among singletons). In conclusion, fertility trends followed the pattern prevailing in the resident country. The relatively good outcome of children whose mothers were born in Finland but who had given birth in Sweden can partly be explained by the healthy migrant effect. PMID

    The methods and costs of measures to restore acidified water areas or prevent further acidification to lakes and streams in Sweden are presented, along with the results of a five-year liming test period. The reduction of sulfur emissions is considered in terms of reducing sulfur content in home heating oils to a 1% maximum, the use of purifiers in industry, and international cooperation to reduce transboundary pollution. A total of over 300 liming projects consuming more than 200,000 tons of liming agents were placed in waters, in bogs and on farms, and on marshes, nominally by use of a centrifugal distributor on land and various spreading methods on water, principally with crushed limestone. Other methods are suggested, and liming results were found to be an improvement of farm soil fertility, a decrease in forest growth, and positive effects on fish populations. Full scale liming is recommended wherever natural buffering has been found to be insufficient.

    The maternal mortality rate in Sweden in the early 20th century was one third that in the United States. This rate was recognized by American visitors as an achievement of Swedish maternity care, in which highly competent midwives attend home deliveries. The 19th century decline in maternal mortality was largely caused by improvements in obstetric care, but was also helped along by the national health strategy of giving midwives and doctors complementary roles in maternity care, as well as equal involvement in setting public health policy. The 20th century decline in maternal mortality, seen in all Western countries, was made possible by the emergence of modern medicine. However, the contribution of the mobilization of human resources should not be underestimated, nor should key developments in public health policy. PMID:15284032

    Haematophagous mites were collected from the vent region and plumage of chickens in six hobby flocks of ornamental breeds in Sweden, one of which included turkeys. Soiled vent skin and feathers, dermatitis, hyperkeratosis, skin necroses and ulcers were observed in 12 necropsied birds from two of the flocks. The mites were identified as the northern fowl mite Ornithonyssus sylviarum (Mesostigmata: Macronyssidae). This was supported by sequence analysis of a 642-bp region in the mitochondrial cytochrome oxidase subunit 1 (COI) gene (COI) in mites collected from five flocks, which showed 97-99% sequence similarity to O. sylviarum by blast analysis. Pairwise sequence comparisons revealed nucleotide variations in the range of 0-2.8%, whereas amino acid sequences were highly conserved. This paper represents one of very few records of O. sylviarum in European poultry, and is the first to report COI sequence data for O. sylviarum from poultry in Europe. PMID:24602037

    The circumstances for the protection of nuclear power plants are special in Sweden. A very important factor is that armed guards at the facilities are alien to the Swedish society. They do not use them. The Swedish concept of physical protection accepts that the aggressor will get into the facility. With this in mind, the Swedish Nuclear Power Inspectorate (SKI) has established the policy that administrative, technical, and organizational measures will be directed toward preventing an aggressor from damaging the reactor, even if he has occupied the facility. In addition, the best conditions possible shall be established for the operator and the police to reoccupy the plant. The author believes this policy is different from that of many other countries. Therefore, he focusses on the Swedish philosophy and techniques for the physical protection of nuclear power plants.

  17. Selling eugenics: the case of Sweden.

    2010-12-20

    This paper traces the early (1910s to 1920s) development of Swedish eugenics through a study of the social network that promoted it. The eugenics network consisted mainly of academics from a variety of disciplines, but with medicine and biology dominating; connections with German scientists who would later shape Nazi biopolitics were strong. The paper shows how the network used political lobbying (for example, using contacts with academically accomplished MPs) and various media strategies to gain scientific and political support for their cause, where a major goal was the creation of a eugenics institute (which opened in 1922). It also outlines the eugenic vision of the institute's first director, Herman Lundborg. In effect the network, and in particular Lundborg, promoted the view that politics should be guided by eugenics and by a genetically superior elite. The selling of eugenics in Sweden is an example of the co-production of science and social order.

    Our aim was to analyze the difference between methods for genotyping of Mycobacterium tuberculosis complex isolates. We collected genotyping results from Restriction Fragment Length Polymorphism (RFLP) and Mycobacterial Interspersed Repetitive Units-Variable Numbers of Tandem Repeat (MIRU-VNTR) in a geographically limited area (Stockholm) during a period of three years. The number and proportion of isolates belonging to clusters was reduced by 45 and 35% respectively when combining the two methods compared with using RFLP or MIRU-VNTR only. The mean size of the clusters was smaller when combining methods and smaller with RFLP compared to MIRU-VNTR. In clusters with confirmed epidemiological links RFLP coincided slightly better than MIRU-VNTR but where there was a difference, the variation in MIRU-VNTR pattern was only in a single locus. In isolates with few IS6110 bands in RFLP, MIRU-VNTR differentiated the isolates more, dividing the RFLP clusters. Since MIRU-VNTR is faster and less labour-intensive it is the method of choice for routine genotyping. In most cases it will be sufficient for epidemiological purposes but true clustering might still be considered if there are epidemiological links and the MIRU-VNTR results differ in only one of its 24 loci.

    The 3rd Annual EULAR Congress, held in Stockholm on 12–15 June 2002, had a turnout of 8300 delegates, almost identical to last year's record attendance level in Prague. The venue was close to ideal, allowing ample space for poster sessions in the exhibition hall. The manned poster sessions were well attended, even on the last day of the Congress. The numerous invited speakers represented the world's elite, allowing the staging of excellent state-of-the-art podium sessions. The aim of attracting the young scientific community was partly achieved, but individual delegates' dependence on industry sponsorship poses potential problems. The organization was a big improvement compared to that of the two previous congresses. Approximately 1800 abstracts were submitted, an increase of 50%, resulting in a higher quality of accepted abstracts. The satellite symposia held every morning and late afternoon were well attended; thus, industry exposure of new products, both in podium sessions and at the exhibitions, was well accommodated. The Annual EULAR Congress consolidates its position as one of the two most important annual congresses of rheumatology, but EULAR economy and commercial aspects are still too dominant in relation to science.

    High resolution reflection seismic methods have proven to be useful tools for locating fracture zones in crystalline rock. Siting of potential high-level nuclear waste repositories is a particularly important application of these methods. By using small explosive sources (15-75 grams), high resolution images of the sub-surface have been obtained in the depth range 100 m to 2 km in Sweden, Canada and elsewhere. Although ambient noise conditions in areas such as the Fennoscandian and Canadian shields are generally low, industrial noise can be high in some areas, particularly at potential sites suitable for repositories, since these are often close to existing infrastructure. In addition, the presence of this infrastructure limits the choice of sources available to the geophysicist. Forsmark, located about 140 km north of Stockholm, is one such potential site where reflection seismics have been carried out. Existing infrastructure includes nuclear reactors for power generation and a low- level waste repository. In the vicinity of the reactors, it was not possible to use an explosive source due to permitting restrictions. Instead, a VIBSIST system consisting of a tractor mounted hydraulic hammer was used in the vicinity of the reactors. By repeatedly hitting the pavement, without breaking it, at predefined sweeps and then stacking the signals, shot records comparable to explosive data could be generated. These shot records were then processed using standard methods to produce stacked sections along 3 profiles within the reactor area. Clear reflections are seen in the uppermost 600 m along 3 of these profiles. Correlation of crossing profiles shows that the strongest reflection (B8) is generated by a gently east-southeast dipping interface. Prior to construction of the reactors, several boreholes were drilled to investigate the bedrock in the area. One of these boreholes was located close to where two of the profiles cross. Projection of the B8 reflection into the

    Large-scale exposure assessments that include both between- and within-city differences in air pollution levels are lacking. The objective of this study was to model long-term particle exposure for the whole of Sweden, separating long-range transport from local sources, which were further separated into combustion and road dust. Annual regional, urban and local traffic PM exposure contributions were modeled for 26,000 addresses from a national survey, using a European scale model, an urban model and a local traffic model. Total PM(10) was overall dominated by the regional contribution, ranging from 3.5 μg/m(3) (northernmost) to 13.5 μg/m(3) (southernmost). Local traffic and urban sources contributed nationally on average to 16% of total PM(10), but for urban populations this contribution was larger (for Stockholm around 30%). Generalized to the Swedish adult population, the average residential exposure contributions from regional, urban and local traffic PM(10) were 10.2, 1.3 and 0.2 μg/m(3), respectively. Corresponding exposure to PM(1) was 5.1, 0.5 and 0.03 μg/m(3), respectively. Long-range transport dominates average Swedish residential PM(1) and PM(10) levels, but for urban populations the contributions from urban and local traffic sources are important and may even dominate for residences close to heavily trafficked roads. The study shows the importance of considering both national and city-scale gradients. The approach to exposure modeling at home addresses of a Swedish cohort includes both the regional scale and the urban and local traffic contributions to total PM exposure. With this we can resolve both between- and within-city gradients in national exposure assessments. The within-city exposure is further divided into a submicron (combustion) and a supermicron (road dust generated by studded tires) part. This gives new possibilities to study health impacts of different particles generated in Scandinavian cities. PMID:23340704

    Qvarsell, R

    1995-01-01

    During the first decades of the 20th century several different kinds of psychotherapeutical technics were used among therapists working on the medical market place. Within the mental hospitals most of the patients did not get any kind of therapy at all, except occupational therapy and sedative drugs. The psychoanalytical theory was in Sweden as in many other countries received with very little enthusiasm and some psychiatrists even wrote articles and books where they tried to prove that Freud was totally wrong. Even if some of Freuds books were translated during the 1920s they did not influence the psychological and psychiatric debate until the 1930s. At the middle of the decade an association for psychoanalysis was established and several famous therapists visited the country and held lectures and courses. Especially among those psychiatrists working with children the interest in psycoanalytical thinking was growing very fast. But many of the other therapists seemed to be more interested in Alfred Adler than in Sigmund Freud and not so few tried to develop a psychological theory and a psychotherapeutical technic of their own. One of these pspychotherapists with a formal education from Vienna but mostly working with her own theory was Tora Sandström. Tora Sandström (1886-1949) established herself as a psychotherapist and with consultation rooms in Stockholm at the middle of the 1930s. Before that, but after her education in Vienna, she had written a psychobiography of the female novelist Victoria Benedictsson. She wanted the book to be accepted as a Ph.D. thesis, but it was rejected. During the following years she wrote two books about the importance of aggressiveness for the psychological development of children. During the 1940s Tora Sandström openly rejected the freudian theory, although she was still practising as a psychotherapist. Many of her colleagues seemed to join her in this escape from the freudian fold and in the intense discussion about the nature

    Tardigrades occur worldwide and in a variety of ecosystems and habitats representing an important component of the micrometazoan biodiversity. Several studies documenting the occurrence of tardigrades in Sweden have been published since the first reports in early 1900, but no comprehensive summary of these studies have been published. We compiled the available information on recorded tardigrades from Sweden, using material from published studies and museum and university collections. In total, our review document 101 species of tardigrades that have been recorded from Sweden (an updated checklist of tardigrades from Sweden will be available online), of which 14 species are new records for the country. The highest number of species was recorded in the northernmost province of Lappland and the more southern provinces of Uppland and Skåne, while much lower species numbers are reported from the middle part of Sweden. This pattern probably represents biased sampling activities of biologists rather than real differences in biodiversity of tardigrades. In view of the few studies that have been made on tardigrade biodiversity in Sweden, the relatively high number of tardigrade species recorded, representing almost a tenth of the species recorded worldwide, indicates that many more species remain to be found. In this respect, more studies of the marine ecosystems along the Swedish west coast and the long Baltic Sea coastline would be of particular interest.

    Introduction of alien species is a major threat to biological diversity. Although public attention typically focuses on the species level, guidelines from the Convention of Biological Diversity define alien species to include entities below species level. This inclusion recognizes that release of nonlocal populations of native species may also result in negative effects on biodiversity. In practice, little is known about the extent, degree of establishment, or the effects on natural gene pools of such releases. Existing information on the releases in Sweden shows that alien populations are spread to a great extent. The most commonly released species include brown trout, Atlantic salmon, Arctic char, common whitefish, Scots pine, Norway spruce, mallard duck, gray partridge, and pheasant. Although millions of forest trees, fish, and birds are released annually, poor documentation makes the geographic and genetic origin of these populations, as well as the sites where they have been released, largely unclear. We provide recommendations for urgently needed first steps relating to the risks and problems associated with release of alien populations.

    The number of practising psychiatrists in Sweden has increased by nearly 30% between the years 1995-2009; however, the profession has suffered serious recruitment difficulties. The Swedish National Board of Health and Welfare estimated that about 5-10% of the population is in need of psychiatric treatment, but only 3-4% seek psychiatric care. Among patients who receive psychiatric care, approximately 47% are treated with psychopharmacology, 13% are treated with psychotherapy and 40% receive both treatments. There are still challenges facing Swedish psychiatry: reduction in waiting times for psychiatric care, broader accessibility of evidence-based treatment methods for all groups of psychiatric patients both in rural and urban areas, and targeting the needs of immigrants and refugees. The allocation of resources to psychiatric research, and development of novel treatment methods are crucially needed. The Swedish government is strongly committed to decreasing the number of suicides, as there are approximately 1,400 individuals lost to suicide every year in a country with a population of around 10 million. Given that nearly 20% of all suicides are amongst psychiatric inpatients, a regulation has been passed regarding the analysis of all completed suicides in the healthcare system. Results from these analyses can be used for increasing quality of treatment.

  6. Sustainable Water Supplies in Uppsala, Sweden?

    2014-05-01

    This is a description of a transdisciplinary three-day project with upper secondary school students around ecosystem services and sustainability. Uppsala (200 000 inhabitants) gets its municipal water from wells in the esker that dominates the landscape in and around the town. This esker was formed by glacial melt water around 11 000 BP, at the end of the latest glaciation and was lifted above sea level by post-glacial land rise from 6000 BP. To keep up the water table in the esker, water from river Fyris is pumped up and infiltrated in the esker. The river is also the recipient of wastewater downstream of the town, and the river runs out into Lake Mälaren that in its turn spills out into the Baltic Sea through Stockholm. The esker and river can thus be a central topic to work around, in Biology and Geography in upper secondary school, concerning recent and future water supplies, quaternary geology, limnology and landscape history. The fieldwork is carried out during three days in a period of three subsequent weeks. 1. One day is used to examine the water quality in the river above the town, organisms, pH, levels of nitrogen and phosphorous, conductivity and turbidity. Then the direction of the water is followed, first up to the infiltration dams on the esker, and then along the esker to the wells in the town. The formation of the esker and other traces in the landscape from the latest glaciation is also studied, as well as the historical use of the esker as a road and as a source of gravel and sand. The tap water that comes from the wells is finally tested in school in the same way as in the river. 2.

    Anton Nyström (1842-1931), practitioner and author, was at the end of the nineteenth and the beginning of the twentieth century a well-known but also controversial personage in Swedish cultural and intellectual life. The posterity remembers him mainly for having introduced the philosophical system of Auguste Comte and founded a Society for Positivism in Sweden as well as having founded an institution ("Arbetarinstitutet") in Stockholm with the purpose to give an all-round education to the working classes through lectures by leading personalities in the world of culture and science. In numerous publications he treated besides medical topics also religious, cultural, social, political and historical themes. Immediately after his medical graduation in May 1868, he went abroad to study dermatology and stayed for this purpose for nearly one and a half years in Vienna, Paris and London. Back in Sweden in the autumn of 1869, he began writing a book with the title "Theoretical and practical essays on skin disorders." This book is for us today interesting because it illustrates the different views of that time on skin diseases held by Hebra in Vienna, Bazin and Hardy in Paris and Wilson and Tilbury Fox in London. In Paris Nyström had been fascinated by Bazin's and Hardy's theories on constitutional diseases and diathetic states and had, as he says, "embraced the doctrines of Bazin". In Vienna, however, he had disapproved of Hebra's way to reject speculations on internal etiology for skin diseases and to look upon them as having mainly an external cause and of his method to treat skin diseases preferably with local remedies. In London he was on very friendly terms with Tilbury Fox, who to his satisfaction also sympathized with the opinions held by Bazin. ...

    Background Experimental and natural human adenovirus-36 (Adv36) infection of multiple animal species results in obesity through increasing adipogenesis and lipid accumulation in adipocytes. Presence of Adv36 antibodies detected by serum neutralization assay has previously been associated with obesity in children and adults living in the USA, South Korea and Italy, whereas no association with adult obesity was detected in Belgium/the Netherlands nor among USA military personnel. Adv36 infection has also been shown to reduce blood lipid levels, increase glucose uptake by adipose tissue and skeletal muscle biopsies, and to associate with improved glycemic control in non-diabetic individuals. Principal Findings Using a novel ELISA, 1946 clinically well-characterized individuals including 424 children and 1522 non-diabetic adults, and 89 anonymous blood donors, residing in central Sweden representing the population in Stockholm area, were studied for the presence of antibodies against Adv36 in serum. The prevalence of Adv36 positivity in lean individuals increased from ∼7% in 1992–1998 to 15–20% in 2002–2009, which paralleled the increase in obesity prevalence. We found that Adv36-positive serology was associated with pediatric obesity and with severe obesity in females compared to lean and overweight/mildly obese individuals, with a 1.5 to 2-fold Adv36 positivity increase in cases. Moreover, Adv36 positivity was less common among females and males on antilipid pharmacological treatment or with high blood triglyceride level. Insulin sensitivity, measured as lower HOMA-IR, showed a higher point estimate in Adv36-positive obese females and males, although it was not statistically significant (p = 0.08). Conclusion Using a novel ELISA we show that Adv36 infection is associated with pediatric obesity, severe obesity in adult females and lower risk of high blood lipid levels in non-diabetic Swedish individuals.

    Irritable bowel syndrome (IBS) is a functional disorder defined by symptoms in the absence of overt pathology. Colonic spirochetosis (CS), defined by histologic observation of spirochetal strains of Brachyspira in colonic biopsies, is uncommon and considered of doubtful significance. We aimed to determine the prevalence of CS in the general population, identify subtle colon pathologies, and evaluate a link with symptoms of IBS. Colonoscopy was performed in 745 subjects (aged 19-70 years, mean age 51 years, 43% male) with biopsies (ileum and 4 colonic sites) from a random population sample, Stockholm, Sweden, who completed a validated questionnaire of gastrointestinal symptoms; IBS was identified by Rome III criteria. CS was identified by histology and immunohistochemistry. In a general population, 17 individuals (2.28%; 95% confidence interval, 1.2%-3.5%) were diagnosed as having CS by histology; 6 (35%) had IBS. CS was always present in the sigmoid colon, but only 14 rectal biopsies. Eosinophils were increased in colon biopsies in CS cases versus controls, in the transverse (P = .02), sigmoid colon (P = .001), and rectum (P = .0005) with subepithelial eosinophil clusters (P = .053). Lymphoid follicles (at any site) were present in 13 CS (P = .0003). There was a 3-fold increased risk of IBS in CS (odds ratio, 3.59; 95% confidence interval, 1.27-10.11; P = .015). Polyps and diverticular disease were similar in CS cases and controls. The prevalence of CS in a general population is 2% and associated with nonconstipating IBS. Colonic eosinophilia with lymphoid follicles may signify the presence of CS.

    Socio-economic analysis (SEA) plays an important role in decision-making on risk management actions for certain chemicals under Multilateral Environmental Agreements (MEAs) in developing countries. This paper showed the first holistic and quantitative SEA case study on that by developing a country-specific SEA framwork and methodologies and applying the case of HBCD phase-out in China under the Stockholm Convention on Persistent Organic Pollutants (POPs). The study indicates that, under the possible scenarios of 10 years and 5 years , the economic costs of HBCD phase-out in China would be between 9.032 and 19.021 billion RMB. Although the total economic costs seems to be significant, it would only have a marginal impact on the house building industry with a likely cost increase by about 0.07‰-0.14‰. Meanwhile, the HBCD phase-out may render significant environmental and health benefits, including about 23-29 tons of HBCD release prevented to the environment, 1.142-1.469 million tons of potentially HBCD contained hazardous wastes avoided, along with significant reduction from 58% up to almost 100% in local environmental concentrations of HBCD, and about 0.0996-0.128 million workers at risk avoided and at least 3.067-4.033 billion RMB of the health care savings. While the scenario of phasing out HBCD over 10 years would be less costly than the scenario of that over 5 years, the later scenario suggested much greater environmental and health benefits for China.

    A new scientific drilling infrastructure is currently under commissioning at Lund University in southern Sweden and is intended primarily for Swedish scientific drilling projects. However, it will be available to the scientific community and even industry when not occupied. The drill rig, a crawler mounted Atlas Copco CT20, was funded by the Swedish Research Council (VR) after an application by the Swedish scientific drilling community under the lead of Prof. Leif Bjelm, Lund University. As a national resource it is, together with support of the Swedish Deep Drilling Program (SDDP) and the Swedish membership in ICDP, part of VR's commitment to scientific drilling. The Atlas Copco CT20 is a top modern, versatile diamond wireline core-drilling rig which can handle P, H and N sizes. It can operate on very small drill sites (500-800 m2) and, thus, leaves a minimal environmental footprint. The crawler makes the rig ideal for operations in remote locations. A total of only 3-4 truckloads is necessary for mobilization of the basic drilling equipment. Main technical specifications are: Depth capacity coring, based on vertical water filled hole: P-size to around 1050 m, hole size 123 mm and core size 85 mm. H-size to around 1600 m, hole size 96 mm and core size 63 mm. N-size to around 2500 m, hole size 76 mm and core size 48 mm. Weight: Complete rig including crawler, wet - 23500 kg Dimensions in (length, width, height) transport position: 11560 x 2500 x 3750 mm. Available in-hole equipment: Complete core retrieval system for PQ, HQ and NQ-sizes, including PHD, HRQ (V-Wall) and NRQ (V-Wall) drill rods covering the maximum drilling depth for each size (see rig depth capacity above). Both dual and triple tube for HQ and NQ-sizes. Casing advancers (PW, HW, NW and BW). Casing PWT, HWT, NW and BW. Bits and reamers. Additional equipment: Mud cleaning and mixing system.

    Over the past decade, significant warming has caused organic-rich permafrost to thaw thereby increasing the amount of soil carbon available for decomposition. The release of greenhouse gases, such as methane (CH4), is predicted to also increase, resulting in a positive feedback cycle due to increased thaw caused by higher atmospheric temperatures. Little is known however about the effect of permafrost thaw on the release of molecular hydrogen (H2) from wetland ecosystems. Vegetated surfaces are thought to be sinks for atmospheric H2. However, as permafrost soils thaw and precipitation events become more frequent, resulting in an increase in inundated areas under anoxic conditions, soils could quickly shift from a sink of atmospheric H2 to a source. This project focused on the effect of changes in soil moisture following precipitation events on the consumption or release of H2 in a subarctic mire in the discontinuous permafrost region near Abisko, Sweden during July 2012. Different habitats were sampled using existing soil gas profiling arrays and a sipper device. In addition, soil temperature and pH data were collected as well as autochamber flux measurements of H2, carbon dioxide, and CH4. All sipper and soil gas profiling array samples were analyzed with a reduced gas (HgO) detector for H2 and a flame ionization detector for CH4. Methane data were collected at all sites and depths to better understand the tight coupling between H2 and CH4. On July 14th and 15th, the site received record precipitation for any 48 hour period. In a thawed Carex spp, dominated site, the concentration of H2 in porewater decreased substantially immediately after the precipitation and slightly more throughout the following week indicating a significant dilution event. A similar effect was observed in an Eriophorum dominated site; however, the behavior of CH4 at these two sites differed in that CH4 responded similarly to H2 after the precipitation event at the Carex spp. site, but CH4

    Purpose. To compare ab interno and ab externo scleral fixation of posterior chamber intraocular lenses (PCIOL) using ultrasound biomicroscopy (UBM). Methods. Randomized patients underwent ab externo or ab interno scleral fixation of a PCIOL. Ultrasound biomicroscopy was performed 3 to 6 months postoperatively, to determine PCIOL centration, IOL distance to the iris at 12, 3, 6, and 9 hours, and haptics placement in relation to the ciliary sulcus. Results. Fifteen patients were enrolled in the study. The ab externo technique was used in 7 eyes (46.6%) and the ab interno in 8 eyes (53.3%). In the ab externo technique, 14 haptics were located: 4 (28.57%) in the ciliary sulcus; 2 (14.28%) anterior to the sulcus; and 8 (57.14%) posterior to the sulcus, 6 in the ciliary body and 2 posterior to the ciliary body. In the ab interno group, 4 haptics (25.0%) were in the ciliary sulcus, 2 (12.50%) anterior to the sulcus, and 10 (75.0%) posterior to the sulcus, 4 in the ciliary body and 6 posterior to the ciliary body. Conclusions. Ab externo and ab interno scleral fixation techniques presented similar results in haptic placement. Ab externo technique presented higher vertical tilt when compared to the ab interno.

    2002-03-01

    Between 1990 and 1999, SO4(2-) deposition in northern Sweden decreased by over 50%. To determine if a corresponding amelioration of stream acidity has occurred, we analyzed trends in anthropogenically driven episodic acidification in five streams during the same time period, using the Boreal Dilution Model (BDM) (Bishop, K. H.; Laudon, H.; Kohler, S. Water Resour. Res. 2000, 36, 1873-1884). Although there was no significant change in the annual average streamwater chemistry, the anthropogenically driven episodic acidification associated with spring flood runoff decreased by between 40% and 80%. A strong correlation between winter SO4(2-) deposition and the anthropogenic component of episodic acidification in these five streams suggests that future reductions of acid deposition will further improve the spring flood acidification situation in northern Sweden. These results argue that reduced emissions of acid precursors have generated significant improvements in the surface water chemistry during episodes associated with spring runoff in northern Sweden.

    1990-01-01

    Transferrin (TF) C subtypes were studied in Swedish Lapps (Saami) and in Swedes from northern, central and southern Sweden, and the allele frequencies were compared with those in other European populations. The Swedish Lapps were found to have the lowest frequency of the TF*C3 allele (1-2%) so far observed in Europe. Most European populations have TF*C3 allele frequencies between 5 and 7%. Finns differ by having high TF*C3 frequencies (13-14%). The relatively high TF*C3 frequencies found in northeastern Sweden (13%) and in central Sweden (9%) are most likely due to eastern influence. Unlike other genetic markers of eastern influence (e.g. TF*DCHI), which are of Asiatic Mongoloid origin, TF*C3 appears to originate from Finno-Ugric populations.

    "Explicit policies on return migration are of rather recent date in most European countries, including Sweden. During the last few years a number of new policy initiatives have been taken in this field. The purpose of this paper is to examine how official Swedish policies on return migration have changed during the last 20 years. The conclusion is that Sweden has moved from a ¿non-policy' in the 1970s, much in opposition to ¿guestworker' or rotation systems, towards an active and explicit policy promoting return in the mid-1990s. The major trends in the country's immigration, emigration and return flows are also presented."

    Radiation therapy has been in use as a cancer treatment for more than 100 years, with its earliest roots traced from the discovery of X rays in 1895 by Wilhelm Rontgen. The field of radiation therapy began to grow in the early 1900s, largely due to the groundbreaking work of Nobel Prize-winning scientist Marie Curie, who discovered the radioactive elements polonium and radium.This began a new era in medical treatment and research. Radium was used in various forms until the mid-1900s, when cobalt and caesium units came into use. Medical cobalt units and linear accelerators have been used to as sources of radiation since the late 1940s. Swedish doctors showed a great interest in this medical specialty from the beginning, making major contributions in the fields of radiobiology, radiophysics and radiotherapy are contributed to doctors of Swedish origin, working mainly those early days in Stockholm. Immediately after the discovery of X rays, the first treatment of patients with these'mysterious rays' took place, with two patients with skin carcinomas being treated by Stenbeck and Sjogren in Stockholm. This article makes a detailed reference to historical data regarding the gradual transformation of a small private outpatient clinic into an academic department with a world-wide recognition.

  8. Ab initio phonon limited transport

    NASA Astrophysics Data System (ADS)

    Verstraete, Matthieu

    We revisit the thermoelectric (TE) transport properties of two champion materials, PbTe and SnSe, using fully first principles methods. In both cases the performance of the material is due to subtle combinations of structural effects, scattering, and phase space reduction. In PbTe anharmonic effects are completely opposite to the predicted quasiharmonic evolution of phonon frequencies and to frequently (and incorrectly) cited extrapolations of experiments. This stabilizes the material at high T, but also tends to enhance its thermal conductivity, in a non linear manner, above 600 Kelvin. This explains why PbTe is in practice limited to room temperature applications. SnSe has recently been shown to be the most efficient TE material in bulk form. This is mainly due to a strongly enhanced carrier concentration and electrical conductivity, after going through a phase transition from 600 to 800 K. We calculate the transport coefficients as well as the defect concentrations ab initio, showing excellent agreement with experiment, and elucidating the origin of the double phase transition as well as the new charge carriers.

    1991-01-01

    This paper analyses health care expenditure in Sweden and compares this with the corresponding expenditure in OECD countries. The definition and measurement problems of health care expenditure are discussed, new figures for the development of health care expenditure are presented and different measures of health care expenditure are provided. We found that health care expenditure has increased by about 20% in constant prices for Sweden between 1980 and 1988, but that health care expenditure as a share of the GDP has dropped during the same period in current prices. Health care expenditure disaggregated on different age groups show for Sweden that in the age group 15-64 years, health care expenditure has not increased in constant prices between 1976 and 1985, but in the oldest age group, health care expenditure has increased considerable during this period. Health care expenditure in Sweden is as high as would be expected, taking into account the degree of economic development and the growth of expenditure during the 80s, and has followed that in comparable OECD countries. However, the relative price is lower, which means that the input of real resources are greater than in other countries. PMID:10115993

  15. Corporatism and health care: a comparison of Sweden and Mexico.

    PubMed

    Frenk, J; González-Block, M A

    1992-01-01

    Up to now, the Swedish health care system has been used as a model for comparisons with other developed nations, chiefly in Northern Europe and the United States. This article departs from the mainstream and poses that similarities along the political factor of corporatism warrant a comparative analysis between the Swedish and Mexican cases. The most widely accepted definitions and typologies of corporatism are reviewed. The arena of manpower policy is used to illustrate the effects of alternative modes of interest representation on health care organization. The final aim of this comparative exercise is to enrich the empirical basis required to build a theory about the complex determinants of health care systems. State corporatism has acted in Mexico largely unchecked by geographical interest representation, in contrast with Sweden where centralist and decentralist forces are more balanced. This finding helps to understand why Sweden and Mexico mark extreme points along the health equity continuum. The comparison underscores the need for Sweden to avoid the risk of weakening the equity basis of its health care system as it moves along its current reform. The importance of these transformations go beyond Sweden, since they will undoubtedly offer new models of thinking and acting for the rest of the world. PMID:10119963

    2009-01-01

    Introduction Insights into effective policy strategies for improved coordination of care is needed. In this study we describe and compare the policy strategies chosen in Denmark and Sweden, and discuss them in relation to interorganisational network theory. Policy practice The policy initiatives to improve collaboration between primary and secondary healthcare in Denmark and Sweden include legislation and agreements aiming at clarifying areas of responsibility and defining requirements, creation of links across organisational boarders. In Denmark many initiatives have been centrally induced, while development of local solutions is more prominent in Sweden. Many Danish initiatives target the administrative level, while in Sweden initiatives are also directed at the operational level. In both countries economic incentives for collaboration are weak or lacking, and use of sanctions as a regulatory mean is limited. Discussion and conclusion Despite a variety of policy initiatives, lacking or poorly developed structures to support implementation function as barriers for coordination. The two cases illustrate that even in two relatively coherent health systems, with regional management of both the hospital and general practice sector, there are issues to resolve in regard to administrative and operational coordination. The interorganisational network literature can provide useful tools and concepts for interpreting such issues. PMID:19340328

    The archive of the Nobel Assembly for Physiology or Medicine in Solna, Sweden, is a remarkable repository that contains reports and dossiers of the Nobel Prize nominations of senior and junior physicians from around the world. Although this archive has begun to be used more by scholars, it has been insufficiently examined by historians of surgery. No other German surgeon was nominated as often as Ferdinand Sauerbruch for the Nobel Prize for Physiology or Medicine in the first half of the 20th century. This contribution reconstructs why and by whom Sauerbruch was nominated, and discusses the Nobel committee evaluations of his work. Political factors did not play an obvious role in the Nobel committee discussions, in spite of the fact that Adolf Hitler in 1937 had prohibited all German citizens to accept the Nobel Prize. The main reasons why Sauerbruch ultimately was not considered prize- worthy were that Sauerbruch's achievements were marked by scientific priority disputes, and that his work was not seen as original enough.

    2008-05-20

    Polonium is the only element with a simple cubic (sc) crystal structure. Atoms in solid polonium sit at the corners of a simple cubic unit cell and no where else. Polonium has a valence electron configuration 6s{sup 2}6p{sup 4} (Z = 84). The low temperature {alpha}-phase transforms into the rhombohedral (trigonal) {beta} structure at {approx}348 K. The sc {alpha}-Po unit cell constant is a = 3.345 A. The beta form of polonium ({beta}-Po) has the lattice parameters, a{sub R} = 3.359 A and a rhombohedral angle 98 deg. 13'. We have performed an ab initio electronic structure calculation by using the density functional theory. We have performed the calculation with and without spin-orbit (SO) coupling by using both the LDA and the GGA for the exchange-correlations. The k-points in a simple cubic BZ are determined by R (0.5, 0.5, 0.5), {gamma} (0, 0, 0), X (0.5, 0, 0), M (0.5, 0.5, 0) and {gamma} (0, 0, 0). Other directions of k-points are {gamma} (0, 0, 0), X (0.5, 0, 0), R (0.5, 0.5, 0.5) and {gamma} (0, 0, 0). The SO splittings of p states at the {gamma} point in the GGA+SO scheme for {alpha}-Po are 0.04 eV and 0.02 eV while for the {beta}-Po these are 0.03 eV and 0.97 eV. We have also calculated the vibrational spectra for the unit cells in both the structures. We find that exchanging of a Po atom by Pb atom produces several more bands and destabilizes the {beta} phase.

    Butalene as a structural isomer of p-benzyne has been studied by using an ab initio GVB wavefunction. The geometry of butalene, which is shown to be almost rectangular, is first optimized as a local minimum on the energy surface at the ab initio level. However, the energy barrier of conversion to p-benzyne is as small as 1.6 kcal/mol, and experimental isolation of butalene is predicted to be difficult from a force-constant analysis.

    Glacially induced, intraplate faults are conspicuous in northern Fennoscandia where they reach trace lengths of up to 150 km with estimated magnitudes of 8 and above (e.g. Lagerbäck and Sundh 2008). Based on a nationwide LiDAR survey (Petersen and Rost 2011), recent studies suggest that glacially induced faults are not, as previously understood, confined to the northernmost parts of Sweden and can also be found in the central parts (Smith et al., 2014). Some of these faults are associated with scarps (and possibly landslides) that strike for more than 5 km giving a recognizable expression on LiDAR data. While LiDAR data provide valuable information, it is important that the presence of the fault is ground truthed, its extent and geometry at depth are unraveled and if possible an estimate on its displacement is given. These together with the surface expression represented by the scarp can then provide some information about their displacement mechanism(s) and earthquake magnitude. In this study, we focused on a recently inferred (Smith et al., 2014), through LiDAR data, post/end-glacial fault near the city of Bollnäs about 250 km north of Stockholm. The prospective fault has about 6 km long scarp expression that is ca. 5 m higher in the western side of the scarp. A multidisciplinary geophysical investigation was conducted during October 2014 to provide information about the fault geometry with respect to the scarp, and displacement in the bedrock. This included high-resolution three-component refraction and reflection seismics, gravity and magnetic measurements, ground penetrating radar, radio-magnetotellurics and direct current geoelectrics. Preliminary results suggest a zone of low-velocity and conductivity that is associated with a magnetic lineament that is horizontally about 50 m offset from the scarp. Depth to bedrock surface is about 10 m (consistent in all the measurements) in the eastern side of the scarp while it is about 20 m in the western side. This

    Epidemiologic data relating multivitamin supplement use to the risk of cardiovascular disease are sparse and inconsistent. We examined the association between self-selected use of low dose multivitamin supplements and the risk of myocardial infarction (MI). Our results are based on data from a large population-based, case-control study of subjects aged 45-70 y residing in Sweden, a country in which consumption of fruits and vegetables is relatively low and foods are not fortified with folic acid. The study included 1296 cases (910 men, 386 women) with a first nonfatal MI and 1685 controls (1143 men, 542 women) frequency-matched to the cases by sex, age and hospital catchment area. Odds ratios (OR) and 95% CI were calculated from unconditional logistic regression models. Among controls, 57% of the women and 35% of the men used dietary supplements; corresponding figures for the cases were 42 and 27%, respectively. Of those taking supplements, 80% used multivitamin preparations. After adjustment for major cardiovascular risk factors, the OR of MI comparing regular users of supplements with nonusers were 0.79 (95% CI 0.63-0.98) for men and 0.66 (95% CI 0.48-0.91) for women. This inverse association was not modified by such healthy lifestyle habits as consumption of fruits and vegetables, intake of dietary fiber, smoking habits and level of physical activity, although never smoking appeared to outweigh the association in women. Findings from this study indicate that use of low dose multivitamin supplements may aid in the primary prevention of MI.

Infections were spread across most coastal counties of Sweden and Finland, but unusually, numerous infections were reported in subarctic regions; cases were reported as far north as 65°N, ≈100 miles (160 km) from the Arctic Circle. Most infections were caused by non-O1/O139 V. cholerae (70 cases, corresponding to 77% of the total, all strains were negative for the cholera toxin gene). An extreme heat wave in northern Scandinavia during summer 2014 led to unprecedented high sea surface temperatures, which appear to have been responsible for the emergence of Vibrio bacteria at these latitudes. The emergence of vibriosis in high-latitude regions requires improved diagnostic detection and clinical awareness of these emerging pathogens. PMID:27314874

    The incidence of gonorrhoea in Sweden has shown a tendency to increase in recent years, particularly in the age-groups 15-19 and 20-24 years. However, an extrapolation of the annual incidence curve to 1970 for the 15-19-year age-group suggests that some deceleration in that increase may be expected. Study of gonococcal complications seen at Göteborg hospitals during the period 1950-59 indicates that the frequency of gonococcal salpingitis is higher than had previously been reported; this is attributed to the inclusion in the material studied of patients from departments other than those exclusively concerned with the venereal diseases. The authors conclude that, in view of the high frequency of gonorrhoea in the young and of gonococcal complications, gonorrhoea in Sweden cannot be considered an unimportant public health problem.

    Investigation of energy conservation behavior started much later in Scandinavian countries than in the United States. There is little research under way in Scandinavian on the conditions under which individuals might be willing to decrease their energy use. Nor is there much information available about how consumers would respond to increases in electricity fees. An energy analyst recently suggested that the greatest potential to save energy in Sweden lies in lifestyle changes because the buildings already meet some of the highest thermal standards in the world. Lifestyle changes would certainly be necessary were Sweden to phase out its nuclear power plants because of environmental concerns. Thus, to find out if a phaseout of nuclear power is feasible in Scandinavia, it is necessary to examine the potential for lifestyle changes in the domestic, or household, sector. 2 tabs.

    Despite the recognition that Rhizobium leguminosarum sv. viciae is the most common symbiont of Vicia species worldwide, there is no available information on rhizobia nodulating native Vicia species in Sweden. We have therefore studied the genetic diversity and phylogeny of root nodule bacteria isolated from V. cracca, V. hirsuta, V. sepium, V. tetrasperma and V. sylvatica growing in different locations in Sweden as well as an isolate each from V. cracca in Tromsø, Norway, and V. multicaulis in Siberia, Russia. Out of 25 isolates sampled from the six Vicia species in 12 different locations, there were 14 different genotypes based on the atpD, recA and nodA gene phylogenies. All isolates were classified into Rhizobium leguminosarum sv. viciae group based on the concatenated atpD and recA phylogeny and the nodA phylogeny.

    The use of intensive forestry on part of the forested area in Sweden increases the production of forest biomass and enables an increased use of such biomass to mitigate climate change. However, with increasing conflicting interests in forests and forestry, the success of such a strategy depends on the public acceptance. In this paper, the results of a mail survey show that although a majority of the general public in Sweden supports measures to increase forest growth, they oppose the use of intensive forestry practices such as the cultivation of exotic tree species, clones, and forest fertilization. The acceptance of such practices is mainly influenced by the perceptions of their environmental consequences. Public acceptance was highest for forest fertilization, whereas clone cultivation was the least accepted practice.

    This study investigated the material/substance flow of polybrominated diphenyl ethers listed in the Stockholm Convention (SC) as persistent organic pollutant (POP-PBDEs) in the most relevant plastic fractions in Nigeria. Considering the prohibition of production and the use of POP-PBDEs and knowing that these pollutants are still contained in electrical and electronic equipment (EEE) and associated wastes (WEEE), it is necessary to determine their flows, especially in developing countries with limited end-of-life management. Following the inventory approach of the SC Guidance and utilizing the existing national e-waste inventory together with monitoring data, a material/substance flow analysis was conducted using the STAN tool. Within the period of 2000 to 2010, the total import for EEE/WEEE in Category 3 and 4 was approximately 8 million tonnes (Mt) containing approximately 2.4 Mt of polymers. For the inventory year 2010, it was estimated that from these polymers, about 0.8 Mt was still in stock and 1.6 Mt has reached the end-of-life. It was also estimated that approximately 1.1 Mt has ended in dumpsites, 0.3 Mt was burned in the open, and 0.2 Mt was recycled. In the plastic fractions, 1,270 t of POP-PBDEs was contained with about 370 t still in use/stock and approximately 900 t has entered the end-of-life phase. All three major end-of-life treatments result in environmental pollution with associated exposure risk. The implementation of the Stockholm Convention represents an important opportunity to improve this management situation in Nigeria and other developing countries.

    The Palaeoproterozoic (2.0-1.8 Ga) Svecokarelian orogen in central Sweden consists of a low-pressure, predominantly medium-grade metamorphic domain (central part of Bergslagen lithotectonic unit), enclosed to the north and south by low-pressure migmatite belts. Two periods of metamorphism (1.87-1.85 and 1.83-1.79 Ga) are known in the migmatite belts. In this study, new U-Th-Pb ion microprobe data on zircon and monazite from twelve samples of locally migmatized gneisses and felsic intrusive bodies determine both protolith and metamorphic ages in four sample areas north of Stockholm, inside or immediately adjacent to the medium-grade metamorphic domain. Two orthogneiss samples from the Rimbo area yield unusually old protolith ages of 1909 ± 4 and 1908 ± 4 Ma, while three orthogneisses from the Skutskär and Forsmark areas yield more typical protolith ages between 1901 ± 3 and 1888 ± 3 Ma. Migmatized paragneiss samples from this and two earlier studies contain a significant detrital component sourced from this 1.9 Ga magmatic suite. They are interpreted to be deposited contemporaneously with or shortly after this magmatism. Migmatization of the paragneiss at Rimbo was followed by intrusion of leucogranite at 1846 ± 3 Ma. Even in the other sample areas to the north (Hedesunda-Tierp, Skutskär and Forsmark), metamorphism including migmatization is constrained to the 1.87-1.85 Ga interval and penetrative ductile deformation is limited by earlier studies in the Forsmark area to 1.87-1.86 Ga. However, apart from a metamorphic monazite age of 1863 ± 1 Ma, precise ages were not possible to obtain due to the presence of only partially reset recrystallized domains in zircon, or highly discordant U-rich metamict and altered metamorphic rims. Migmatization was contemporaneous with magmatic activity at 1.87-1.84 Ga in the Bergslagen lithotectonic unit involving a mantle-derived component, and there is a spatial connection between migmatization and this magmatic phase in the

  4. The organic geochemistry of the Alum Shale, Sweden

    Organic matter in the Alum Shale of Sweden has been affected post-depositionally by irradiation from U decay. Effects include: (1) lowering of kerogen H/C ratios; (2) decrease in amount of extractable bitumen; (3) increased aromaticity. Higher thermal maturity of Alum Shale bitumen than kerogen in Central Sweden suggest bitumen migration into the shale. The thermal immaturity of both Alum Shale bitumen and kerogen in Eastern Sweden (Gotland and Oland) indicate that Gotland's oil has either migrated from an area of higher thermal maturity or is the result of very localized heating, possibly from an igneous intrusion. Zn, Cu and Pb concentrations in asphaltenes from the Alum Shale show an inverse relationship with thermal maturity. Experimental hydrous pyrolysis of Alum Shale suggest that Zn, Cu and, to a lesser extent Pb, are mobile during petroleum generation in both bitumen and brine, whereas U is immobile. Nitrogen in naturally occurring gases from the Alum Shale of Ostergotland, Sweden is atmospheric in origin based on ratios of N{sub 2}/Ar. Helium is derived from the radioactive decay of U-based on He{sub 3} He{sub 4} ratios. {delta}{sup 34}S values of Alum Shale pyrite show a fractionation with coeval seawater of approximately 35 per mil, which along with high total S concentrations of over 15% in some samples, implies extensive metabolism of organic matter during early diagenesis by sulfate reducing bacteria. Pyrite {delta}{sup 34}S values are lighter than coexisting organic sulfur in the kerogen by an average of near 7 per mil. The difference is believed to be the result of rite formation earlier and at a relatively shallower sediment depth than organo-sulfur compounds due to the greater reactivity of iron with bacterially released hydrogen sulfide than organic matter.

    The current situation with preoperative skin preparation in Sweden is described. Patients are given two preoperative washes with chlorhexidine scrub, and are sent to theatre on a clean bed, so no extra linen is required. Wound infection rates are acceptably low, and use of chlorhexidine has also assisted in reduction of infection associated with central venous catheters. Use of chlorhexidine scrub is recommended to help healing of infected wounds.

    Tularaemia is a vector-borne infectious disease. A large majority of cases transmitted to humans by blood-feeding arthropods occur during the summer season and is linked to increased temperatures. Therefore, the effect of climate change is likely to have an effect on tularaemia transmission patterns in highly endemic areas of Sweden. In this report, we use simulated climate change scenario data and empirical data of temperatures critical to tularaemia transmission to forecast tularaemia outbreak activity. The five high-endemic counties: Dalarna, Gävleborg, Norrbotten, Värmland and Örebro represent only 14.6% of the total population of Sweden, but have recorded 40.1–81.1% of the number of annual human tularaemia in Sweden from 1997 until 2008. We project here earlier starts and a later termination of future tularaemia outbreaks for the time period 2010–2100. For five localised outbreak areas; Gagnef (Dalarna), Ljusdal (Gävleborg), Harads (Norrbotten), Karlstad (Värmland) and Örebro municipality (Örebro), the climate scenario suggests an approximately 2°C increase in monthly average summer temperatures leading to increases in outbreak durations ranging from 3.5 weeks (Harads) to 6.6 weeks (Karlstad) between 2010 and 2100. In contrast, an analysis of precipitation scenarios indicates fairly stable projected levels of precipitation during the summer months. Thus, there should not be an increased abundance of late summer mosquitoes that are believed to be main vectors for transmission to humans in these areas. In conclusion, the results indicate that the future climate changes will lead to an increased burden of tularaemia in high-endemic areas of Sweden during the coming decades. PMID:20052432

    From medieval times, care of the emotionally disturbed in Sweden has shifted between moralistic and enlightened approaches. In this century through the 1960s, organic methods have predominated, with emphasis on description and precise diagnosis. Psychodynamic treatment has been only reluctantly accepted until the past decade, with child psychiatrists and psychologists at the forefront. Norway has typically been most progressive in the establishment of psychoanalytic and other psychodynamic movements in Scandinavia, with Sweden following and Denmark often lagging behind. In 1970, Norway became the first Scandinavian country to require training in psychotherapy for psychiatrists. Sweden remained more conservative for years, both in adherence to the organic model at one extreme, and in supporting one of the most orthodox psychoanalytic movements in the world, at the other. During the 1970s, however, it became increasingly more common for psychiatrists in Sweden to seek training in psychotherapy through a variety of organizations, established since the early 1930s and operating independently of each other. In 1978, a uniform state program in psychotherapy was developed with theoretical and practical requirements, and is scheduled in the near future to become obligatory for psychiatrists, psychologists, and various other mental health professionals. The paramedical personnel has become increasingly more involved in mental health care during the past decade. In delivery of care, the "sectorization" principle has become central, and is likely to set the tone for the future. With the entire country divided into local catchment areas, the direction will be toward psychodynamic approaches integrated with traditional organic models, open care, decentralization, planned prophylaxis, and full collaboration of all mental health professionals and social agencies.

In areas with high radioactive fallout an increase in the amount of lightning flashes was observed during the 1986 thunderstorm season. A statistical test shows that there is a risk of less than 1% that the observed difference has occurred by mere chance. copyrightAmerican Geophysical Union 1987

    The role of arsenic in Sweden is generally described, including raw materials, exports/imports, products, consumption, etc. An attempt was also made to estimate the transport of arsenic in Sweden. The quantities of arsenic in raw materials, the emissions of arsenic from such processes as copper smelters and chemical industries, and the amounts of products containing arsenic were calculated. The studies show that a copper smelter is the main user of arsenical materials, the very largest emitting source and also the plant which manufacturers most arsenic products. A summary of measurements of arsenic in air, water and soil in Sweden has also been made. The concentrations near a smelter, in the Baltic, in cities and in "clean-air areas" are given. The efforts made to date to reduce the emissions of arsenic and the measures planned for the next few years are described. A reduction has already been achieved and a further rather large decrease will come, especially in arsenic levels in water. The possibilities of minimizing the use of materials and products containing arsenic is also discussed. PMID:908306

During this period postgraduate training, dental health, and the organization of child dental care have changed considerably. Aim. To investigate services provided by specialists in paediatric dentistry in Sweden in 2008, and to compare with data from previous surveys. Design. The same questionnaire was sent to all 30 specialist paediatric dental clinics in Sweden that had been used in previous surveys. Comparisons were made with data from 1983, 1989, 1996 and 2003. Results. Despite an unchanged number of specialists (N = 81 in 2008), the number of referrals had increased by 16% since 2003 and by almost 50% since 1983. There was greater variation in reasons for referrals. The main reason was still dental anxiety/behaviour management problems in combination with dental treatment needs (27%), followed by medical conditions/disability (18%), and high caries activity (15%). The use of different techniques for conscious sedation as well as general anaesthesia had also increased. Conclusions. The referrals to paediatric dentistry continue to increase, leading to a heavy work load for the same number of specialists. Thus, the need for more paediatric dentists remains.

    The responsibility for healthcare in Sweden is shared by the central government, county councils and municipalities. The counties and municipalities are free to make their own prioritizations within the framework of the state healthcare laws. To guide prioritization of healthcare resources in Sweden, there is consensus that cost-effectiveness constitutes one of the three principles. The objective of this paper is to describe how cost-effectiveness, and hence health economic evaluations (HEE), have a role in pricing decisions, reimbursement of pharmaceuticals as well as the overall prioritization and allocation of resources in the Swedish healthcare system. There are various organizations involved in the processes of implementing health technologies in the Swedish healthcare system, several of which consider or produce HEEs when assessing different technologies: the Dental and Pharmaceutical Benefits Agency (TLV), the county councils' group on new drug therapies (NLT), the National Board of Health and Welfare, the Swedish Council on Health Technology Assessment (SBU), regional HTA agencies and the Public Health Agency of Sweden. The only governmental agency that has official and mandatory guidelines for how to perform HEE is TLV (LFNAR 2003:2). Even though HEEs may seem to have a clear and explicit role in the decision-making processes in the Swedish healthcare system, there are various obstacles and challenges in the use and dissemination of the results.

    Overexpression of platelet-derived growth factor (PDGF) has been observed in lung and pleural tumors. The aim of this study was to evaluate the diagnostic and prognostic role of serum PDGF in pleural mesothelioma (PM). Four groups of subjects were studied: 93 malignant PM patients, 33 primary non small cell lung cancer patients, 51 subjects exposed to asbestos, defined as high-risk controls, and 24 healthy controls. PDGF-AB mean concentration was higher in PM patients (45.8 ng/ml) than in high-risk controls (33.1 ng/ml) and healthy controls (26.8 ng/ml). Using the cut-off level of 49.8 ng/ml, corresponding to the mean+2SD of PDGF-AB in healthy controls, 43% of PM patients showed positive PDGF-AB levels. Survival was evaluated in 82 PM patients. At the end of the follow-up (median 9.8 months) 80.5% of patients had died. Median survival was 13.1 and 7.9 months for patients with PDGF-AB lower and higher than the cut-off, respectively. Adjusting for age, sex, histology and platelet count, positive PDGF-AB levels were associated with lower survival (OR=1.2, 95%CI: 0.9-1.6), even if not significantly so. In conclusion, serum PDGF may represent a useful additional parameter to prognostic factors already available for PM.

    The chemical composition of groundwater surrounding a high level radioactive waste repository is of importance to many factors that affect repository performance. The geochemical characteristics of Swedish groundwater systems are governed by successive mixing events between several end-member waters during their paleogeographic evolution. An approach is proposed here to investigate the spatial and temporal evolution of groundwater geochemical conditions by coupling hydrogeological and geochemical models in a sequential way. The procedure combines hydrogeological results by others [1,2] of a discrete fracture network using CONNECTFLOW with a mixing and reaction-path simulation using PHREEQC. The hydrological results contain mixing proportions of four reference waters (a deep brine, glacial meltwater, marine water, and meteoric infiltration) at each time step and at every node of the 3D model domain. In this work, mixing fractions are fed into PHREEQC using software developed to build formatted input files and to extract the information from output files for subsequent plotting and analysis. The geochemical calculations included both chemical mixing and equilibrium reactions with selected minerals: calcite, chalcedony and an Fe(III) oxyhydroxide. Some results for the Forsmark site, about 170 km north of Stockholm, Sweden, are graphically presented. Cross sections, where each node is color-coded with respect to an important variable (pH, Eh or concentrations of main elements), are used to visualize the future evolution of the site. Sensitivity analyses were made to evaluate the effects of the different reactions and/or assumptions. The proposed methodology has proved useful for evaluating the future geochemical evolution of the repository sites and to increase the confidence in the site descriptions. (authors)

    In view of poor constraints on historical combustion emissions, past environmental loadings of black carbon (BC) and polycyclic aromatic hydrocarbon (PAH) were reconstructed from dated lake sediment cores collected 70 km south of Stockholm, Sweden. Compared to several dramatic variations over the recent 150 years, the preindustrial loadings were steady within {+-}50% through the entire medieval with BC fluxes of 0.071 g m{sup -2} yr{sup -1} and PAH fluxes of 6 g m{sup -2} yr{sup -1}. In the wood-burning dominated century leading up to the industrial revolution around 1850, increasing BC fluxes were leading PAH fluxes. BC fluxes reached their millennial-scale maximum around 1920, whereas PAH fluxes increased exponentially to its record maximum around 1960, 50-fold above preindustrial values. For 1920-1950, BC fluxes consistently decreased as PAH fluxes kept increasing. Coal and coke represented >50% of the Swedish energy market in the 1930s. Combined with sharply decreasing (1,7-)/(1,7{+-}2,6-dimethylphenanthrene), indicative of diminishing wood combustion, and decreasing methylphenanthrenes/phenanthrene, indicative of higher-temperature combustion (coal instead of wood), the sediment archive suggests that the relative BC/PAH emission factors thus are lower for coal than for wood combustion. For the first time, both BC and PAH fluxes decreased after 1960. This trend break is a testament to the positive effects of decreasing reliance on petroleum fuels and a number of legislative actions aimed at curbing emissions and by 1990, the loading of BC was back at preindustrial levels, whereas that of PAH were the lowest since the 1910s. However, for the most recent period (1990-2004) the BC and PAH fluxes are no longer decreasing. 55 refs., 3 figs.

    2013-01-01

    Introduction In Sweden, means-tested social assistance serves as a temporary, last resort safety net. However, increasing numbers of people are receiving it for longer periods and about a third has assistance for more than a year. The aim of this study was to explore the ways social assistance recipients manage long lasting adversity and their roles as active, rather than passive, agents in this process, using a resilience perspective. Method The study is based on thirteen in-depth interviews with long-term social assistance recipients from diverse areas in Stockholm County. The interviews were guided by narrative inquiry to interpret and construct stories of experiences and are part of a larger qualitative study exploring experiences of living on social assistance in Sweden. Results Experiences of cumulative adversity during many years compounded recipients’ difficulties in finding ways out of hardship. They had different strategies to deal with adversities, and many had underlying “core problems”, including mental health problems, which had not been properly resolved. Recipients’ showed resistance in adverse situations. Some made attempts to find ways out of hardship, whereas others struggled mainly to achieve a sense of mastering life. They received important support from individual professionals in different authorities, but mostly the help from the welfare system was fragmented. Conclusions Social assistance recipients in this study demonstrated agency in ways of managing long lasting difficulties, sometimes caused by “core problems”, which were often accumulated into complex difficulties. Resilience was about keeping going and resisting these difficulties. To find ways out of social assistance required help from different welfare agencies and professionals and was hindered by the fragmentation of services. This study shows that there is a need for more long-term personalised, comprehensive support, including interventions both to increase

    Ab interno trabeculectomy is one among several recently introduced minimally invasive glaucoma surgeries that avoid a conjunctival incision and full-thickness sclerostomy involved in traditional glaucoma surgery. Ablation of the trabecular meshwork and inner wall of Schlemm's canal is performed in an arcuate fashion via a clear corneal incision, alone or in combination with phacoemulsification cataract surgery. Intraocular pressure reduction following ab interno trabeculectomy is limited by resistance in distal outflow pathways and generally stabilizes in the mid-to-high teens. Relief of medication burden has been demonstrated by some studies. A very low rate of complications, most commonly transient hyphema and intraocular pressure elevations in the immediate postoperative period, have been reported. However, available data are derived from small retrospective and prospective case series. Randomized, controlled trials are needed to better elucidate the potential merits of ab interno trabeculectomy in the combined setting versus phacoemulsification cataract surgery alone and to compare it with other minimally invasive glaucoma surgeries.

    Over the past few years, demand for infrastructures has continuously increased in Sweden. The authorities are expected to invest significantly on infrastructures especially those that are environmentally friendly and aim at reducing CO2 emission. Due to limited surface accessibility, the country will particularly move towards developing more and more subways, train tunnels, underground highways and bypasses. The focus will then obviously be in major cities where the underground infrastructures have to be constantly developed or expanded to facilitate the daily life and transportation. The degree to which we can understand geological conditions where these structures are going to be constructed also has great economical and environmental effects. What, however, makes urban environment challenging target for geophysical investigations is the various sources of noise and restriction both in time and space, which require the equipment to be versatile and to produce minimal disruption as well as fast to set up and pack. As a part of a nation-wide, an academia-industry partnership, project (TRUST, TRansparent Underground STructure), we have developed a multicomponent broadband digital-based sensor seismic landstreamer system that is particularly geared for noisy environments and areas where high-resolution images of the subsurface are needed. The streamer has been tested for its reliability in various locations (e.g., part of the Stockholm Bypass) and for various targets one which was a planned underground train tunnel in the city of Varberg, southwest Sweden that is the focus of this presentation. Potential targets were bedrock surface, fracture zones, weak and shear zones. During nearly three weeks, totally about 7.5 km long, comprising 25 seismic profiles using a source and receiver spacing of 2-4 m, was acquired. A novel approach in the data acquisition was to combine the landstreamer with wireless sensors in areas where accessibility was restricted and, to provide

    The MELCOR computer code has been used to model four of the large-scale aerosol behavior experiments conducted in the Containment System Test Facility (CSTF) vessel. Tests AB5, AB6 and AB7 of the ABCOVE program simulate the dry aerosol conditions during a hypothetical severe accident in an LMFBR. Test LA2 of the LACE program simulates aerosol behavior in a condensing steam environment during a postulated severe accident in an LWR with failure to isolate the containment. The comparison of code results to experimental data show that MELCOR is able to correctly predict most of the thermal-hydraulic results in the four tests. MELCOR predicts reasonably well the dry aerosol behavior of the ABCOVE tests, but significant disagreements are found in the aerosol behavior modelling for the LA2 experiment. These results tend to support some of the concerns about the MELCOR modelling of steam condensation onto aerosols expressed in previous works. During these analyses, a limitation in the MELCOR input was detected for the specification of the aerosol parameters for more than one component. A Latin Hypercube Sampling (LHS) sensitivity study of the aerosol dynamic constants is presented for test AB6. The study shows the importance of the aerosol shape factors in the aerosol deposition behavior, and reveals that MELCOR input/output processing is highly labor intensive for uncertainty and sensitivity analyses based on LHS.

  19. Surficial geology indicates early Holocene faulting and seismicity, central Sweden

    In Sweden, knowledge of the location and timing of glacially induced faulting and seismicity is critical to effective engineering of a long-term nuclear disposal facility. To improve understanding and modeling of the complex ice-induced and tectonic stresses associated with glacially induced faulting, field studies detailing the location and timing of movement of such structures are required. Although the fault has not been confirmed in the bedrock, multi-proxy surficial geologic evidence indicates that the recently discovered scarp in Bollnäs is such a structure. Machine-excavated trenches across the scarp reveal landsliding down the scarp and, in one location, faulted and vertically offset fine-grained glacial sediments. The presence of water-escape structures in trenches excavated on a topographic high strongly suggests a co-seismic origin derived from earthquake magnitudes >5.5. Numerous landslides in till exist in the region as well. Four slopes with landslides were examined in detail, and the factors of safety for these slopes indicate stable conditions and suggest a seismic trigger. Basal radiocarbon dates from peat bogs located stratigraphically above the landslides provide minimum limiting ages for the co-seismic landslides. The oldest date indicates sliding prior to 10,180 calendar years before the present. The proposed Bollnäs Fault is 400 km south of the so called Lapland Fault Province. To date, it is the southernmost confirmed glacially induced fault in Sweden. The results of this study are consistent with existing modeling results that indicate fault instability in this region of central Sweden following deglaciation.

  20. Uranium in the Upper Cambrian black shale of Sweden

    1955-01-01

    The Peltura zone of the Upper Cambrian black shales of Sweden contains about 0.02 percent uranium. Maximum amounts are present in rocks deposited in an embayment in the sea and in rocks in or closely adjacent to that part of the vertical sequence that contains maximum amounts of distillable oil, total organic matter, pyrite, and a black highly uraniferous kerogen called "kolm". Available data suggest that the precipitation of uranium is favored by a low redox potential and that the uranium in the shale matrix may be in fine-grained kolm.

    This article uses data from a field experiment in Sweden to analyze the effects of active placement efforts. In particular, the relative efficiency between combining job-search monitoring and job-search assistance, and monitoring alone, is analyzed. Although the impact estimates are generally imprecisely estimated, a general conclusion is that placement programs are effective policies in increasing the job exit rate for various groups of unemployed. I find that monitoring of job search is an efficient method to increase off-unemployment exit rate both alone and combined with job-search assistance services. The results, however, indicate that the combined services generate more permanent job exits. PMID:25201049

    Non-contractible quality dimensions are at risk of degradation when the provision of public services is privatized. However, privatization may increase quality by fostering performance-improving innovation, particularly if combined with increased competition. We assemble a large data set on elderly care services in Sweden between 1990 and 2009 and estimate how opening to private provision affected mortality rates - an important and not easily contractible quality dimension - using a difference-in-difference-in-difference approach. The results indicate that privatization and the associated increase in competition significantly improved non-contractible quality as measured by mortality rates. PMID:27394007

    In this article we compare cooperation among Colombian and Swedish children aged 9–12. We illustrate the dynamics of the prisoner's dilemma in a new task that is easily understood by children and performed during a physical education class. We find no robust evidence of a difference in cooperation between Colombia and Sweden overall. However, Colombian girls cooperate less than Swedish girls. We also find indications that girls in Colombia are less cooperative than boys. Finally, there is also a tendency for children to be more cooperative with boys than with girls on average.

    Sweden has a well developed welfare system and until fairly recently the needs of family carers have received limited attention. However, there is now a growing acceptance of the need to provide better and more sensitive support services. Using questionnaires validated in the UK and translated into Swedish, this series of four articles considers the difficulties, satisfactions and coping mechanisms of a sample of Swedish carers, identifying the implications of the results for the design and delivery of healthcare interventions. This article focuses on carers' perceived difficulties and their satisfaction with existing levels of help.

    The project "Energy and Society," sponsored by the Swedish Secretariat for Futures Studies, has studied different indigenous energy sources as alternatives to imported oil in Sweden. One alternative is nuclear energy, antoer is renewable energy. Large uncertainties are associated with both alternatives today. The main characteristics of an energy policy for the rest of the century that does not foreclose either of these options have been identified. Such a policy will have to be based on an understanding of similarities and differences between the alternatives. A nuclear and a solar energy system have been outlined as a basis for an analysis of technical, economic, and institutional issues.

    In this work the effect of strain rate on the tensile strength of fused deposition modeling parts built with Acrylonitrile-butadiene-styrene (ABS) and ABS plus material is presented. ASTM D638-02a specimens were built with ABS and ABS plus and they were tested on a Schenck Trebel Co. tensile test machine at three different test speeds, equal, lower, and higher to the test speed required by the ASTM D638-02a standard. The experimental tensile strength results were compared and evaluated. The fracture surfaces of selected specimens were examined with a scanning electron microscope, to determine failure mode of the filament strands. It was found that, as the test speed increases, specimens develop higher tensile strength and have higher elastic modulus. Specimens tested in the highest speed of the experiment had on average about 10% higher elastic modulus and developed on average about 11% higher tensile strength.

    We present a multiwavelength study of the close binary AB Dor Ba/b (Rst137B). Our study comprises astrometric orbit measurements, optical spectroscopy, X-ray and radio observations. Using all available adaptive optics images of AB Dor B taken with VLT/NACO from 2004 to 2009, we tightly constrain its orbital period to 360.6 ± 1.5 days. We present the first orbital solution of Rst 137B and estimate the combined mass of AB Dor Ba+b as 0.69+0.02-0.24 M⊙, slightly exceeding previous estimates based on IR photometry. Our determined orbital inclination of Rst 137B is close to the axial inclination of AB Dor A inferred from Doppler imaging. Our VLT/UVES spectra yield high rotational velocities of ≥30 km s-1 for both components Ba and Bb, in accord with previous measurements, which corresponds to rotation periods significantly shorter than one day. Our combined spectral model, using PHOENIX spectra, yields an effective temperature of 3310 ± 50 K for the primary and approximately 60 K less for the secondary. The optical spectra presumably cover a chromospheric flare and show that at least one component of Rst 137B is significantly active. Activity and weak variations are also found in our simultaneous XMM-Newton observations, while our ATCA radio data yield constant fluxes at the level of previous measurements. Using evolutionary models, our newly determined stellar parameters confirm that the age of Rst 137B is between 50 and 100 Myr.

    The zoonotic disease tularemia is endemic in large areas of the Northern Hemisphere, but research is lacking on patterns of spatial distribution and connections with ecologic factors. To describe the spatial epidemiology of and identify ecologic risk factors for tularemia incidence in Sweden, we analyzed surveillance data collected over 29 years (1984-2012). A total of 4,830 cases were notified, of which 3,524 met all study inclusion criteria. From the first to the second half of the study period, mean incidence increased 10-fold, from 0.26/100,000 persons during 1984-1998 to 2.47/100,000 persons during 1999-2012 (p<0.001). The incidence of tularemia was higher than expected in the boreal and alpine ecologic regions (p<0.001), and incidence was positively correlated with the presence of lakes and rivers (p<0.001). These results provide a comprehensive epidemiologic description of tularemia in Sweden and illustrate that incidence is higher in locations near lakes and rivers.

    2015-01-01

    The Swedish welfare state, once developed to create a new society based on social equality and universal rights, has taken on a partly new direction. Extensive choice reforms have been implemented in social services and an increasing proportion of tax-funded social services, including child day care, primary and secondary schools, health care, and care of the elderly, is provided by private entrepreneurs, although funded by taxes. Private equity firms have gained considerable profits from the welfare services. The changes have taken place over a 20-year period, but at an accelerated pace in the last decade. Sweden previously had very generous sickness and unemployment insurance, in terms of both duration and benefit levels, but is falling behind in terms of generosity, as indicated by increasing levels of relative poverty among those who depend on benefits and transfers. Increasing income inequality over the past 20 years further adds to increasing the gaps between population groups. In some respects, Sweden is becoming similar to other Organisation for Economic Co-operation and Development countries. The article describes some of the changes that have occurred. However, there is still widespread popular support for the publicly provided welfare state services. PMID:26460449

    The mosquito-borne Inkoo virus (INKV) is a member of the California serogroup in the family Bunyaviridae, genus Orthobunyavirus. These viruses are associated with fever and encephalitis, although INKV infections are not usually reported and the incidence is largely unknown. The aim of the study was to determine the prevalence of anti-INKV antibodies and associated risk factors in humans living in northern Sweden. Seroprevalence was investigated using the World Health Organization Monitoring of Trends and Determinants in Cardiovascular Disease study, where a randomly selected population aged between 25 and 74 years (N = 1,607) was invited to participate. The presence of anti-INKV IgG antibodies was determined by immunofluorescence assay. Seropositivity for anti-INKV was significantly higher in men (46.9%) than in women (34.8%; P < 0.001). In women, but not in men, the prevalence increased somewhat with age (P = 0.06). The peak in seropositivity was 45–54 years for men and 55–64 years for women. Living in rural areas was associated with a higher seroprevalence. In conclusion, the prevalence of anti-INKV antibodies was high in northern Sweden and was associated with male sex, older age, and rural living. The age distribution indicates exposure to INKV at a relatively early age. These findings will be important for future epidemiological and clinical investigations of this relatively unknown mosquito-borne virus. PMID:26928830

    This paper discusses the energy savings that could be obtained in Sweden by instituting specific standards for five appliances: Refrigerators, freezers, dishwashers, clothes washers, and clothes dryers. At the present time, Sweden has no minimum energy efficiency standards for residential appliances. This paper discusses the energy savings that could be obtained by instituting specific standards for five product types (refrigerators, freezers, dishwashers, clothes washers, and dryers) starting in 1995. A methodology similar to that used in analyses for the European Community was employed in this study. In the Swedish study, we used appliance test data developed by the Swedish consumer agency, Konsument Verket, to estimate new unit energy consumption for each product type. Shipments, saturations, energy use, and demographic data were input to a spreadsheet model that sums energy consumption for each product type over the period 1990--2010. Both a base case and a standards case scenario are simulated for each of the five appliance types. It was found that electricity use for these five products can be reduced by 12% over the time period from 1990--2010. Most of the energy savings come from instituting efficiency standards for refrigerators and freezers. For each product class type, the impact on manufacturer offerings is discussed. For example, for simple refrigerators, eleven 1990 models meet the 1995 standard and six models meet the 2000 standard out of a total of 63 models.

  14. Trends in "avoidable" mortality in Sweden, 1974-1985.

    Westerling, R

    1992-01-01

    STUDY OBJECTIVE--The aim was to analyse trends in "avoidable" mortality in Sweden, and to contribute to the methodology of avoidable mortality as an index of the quality of care. SETTING AND PARTICIPANTS--All deaths of Swedish citizens and other residents in Sweden during the period 1974-1985 were analysed as to causes of death between ages 0 and 64 years. MEASUREMENTS AND MAIN RESULTS--Total mortality delined during the 12 year period studied. Avoidable causes of death were grouped into preventable and treatable causes according to Rutstein's classification. In men, treatable diseases declined more during the 12 year period studied than did total mortality. When lung cancer was excluded, preventable diseases declined for both sexes. Certain avoidable causes of death decreased compared to total mortality, while some others showed an increase. The death rate increased for some avoidable causes of death such as pneumonia other than viral. In women death rates increased for chronic bronchitis and emphysema as well as for malignant neoplasms of trachea, bronchus, and lung, while for boys aged 1-14 years bronchitis NOS and asthma showed an increasing death rate. CONCLUSIONS--The study indicates that the avoidable mortality method is sensitive enough to describe important changes in the mortality pattern. The explicit definition of treatable and preventable causes of death constitutes a methodological development in epidemiological analysis of this type. Further studies on the quality of care should combine this method with other methods examining the structure and process of health care. PMID:1479317

    Western countries have reported an increased risk of maternal mortality among African immigrants. This study aimed to identify cases of maternal mortality among immigrants from the Horn of Africa living in Sweden using snowball sampling, and verify whether they had been classified as maternal deaths in the Cause of Death Registry. Three "locators" contacted immigrants from Somalia, Eritrea, and Ethiopia to identify possible cases of maternal mortality. Suspected deaths were scrutinised through verbal autopsy and medical records. Confirmed instances, linked by country of birth, were compared with Registry statistics. We identified seven possible maternal deaths of which four were confirmed in medical records, yet only one case had been classified as such in the Cause of Death Registry. At least two cases, a significant number, seemed to be misclassified. The challenges of both cultural and medical competence for European midwives and obstetricians caring for non-European immigrant mothers should be given more attention, and the chain of information regarding maternal deaths should be strengthened. We propose a practice similar to the British confidential enquiry into maternal deaths. In Sweden, snowball sampling was valuable for contacting immigrant communities for research on maternal mortality; by strengthening statistical validity, it can contribute to better maternal health policy in a multi-ethnic society.

    It is pointed out that with increased computer power and improved computational techniques, such as the gradients developed in recent years, it is becoming practical to compute spectra ab initio, from the fundamental constants of nature, for systems of increasing complexity. The present investigation has the objective to explore several possible ab initio approaches to spectra, giving particular attention to infrared and nonresonance Raman. Two approaches are discussed. The sequential approach, in which first the electronic part and then later the nuclear part of the Born-Oppenheimer approximation is solved, is appropriate for small systems. The simultaneous approach, in which the electronic and nuclear parts are solved at the same time, is more appropriate for many-atom systems. A review of the newer quantum gradient techniques is provided, and the infrared and Raman spectral band contours for the water molecule are computed.

    2016-01-01

    Ab interno trabeculectomy is one among several recently introduced minimally invasive glaucoma surgeries that avoid a conjunctival incision and full-thickness sclerostomy involved in traditional glaucoma surgery. Ablation of the trabecular meshwork and inner wall of Schlemm’s canal is performed in an arcuate fashion via a clear corneal incision, alone or in combination with phacoemulsification cataract surgery. Intraocular pressure reduction following ab interno trabeculectomy is limited by resistance in distal outflow pathways and generally stabilizes in the mid-to-high teens. Relief of medication burden has been demonstrated by some studies. A very low rate of complications, most commonly transient hyphema and intraocular pressure elevations in the immediate postoperative period, have been reported. However, available data are derived from small retrospective and prospective case series. Randomized, controlled trials are needed to better elucidate the potential merits of ab interno trabeculectomy in the combined setting versus phacoemulsification cataract surgery alone and to compare it with other minimally invasive glaucoma surgeries.

  8. Towards a LiDAR based geomorphological database of Sweden

    Peterson, Gustaf; Smith, Colby A.

    2013-04-01

    Geomorphological maps can be important for both societal development and scientific research especially with the use of new technology and consideration for the end user's needs. Since 2009, the Swedish mapping agency (Lantmäteriet) has been using airborne light detection and ranging (LiDAR) to create a detailed "bare earth" digital elevation model (DEM) of Sweden. Presently, a LiDAR derived DEM with 2 m horizontal and 0.25 m vertical resolution exist for about half of the country. This data set enables viewing of the landscape in a new more detailed way; landforms never before seen can now be delineated easily in a desktop environment. We are using this DEM to map the geomorphology, bringing into existence a highly detailed, digitial, geomorphologic database and map. While prior geomorphological maps exist for Sweden, the new map being compiled by the Geological Survey of Sweden (SGU) will be the first one to be derived from and presented in an entirely digital format. With the use of GIS technology, it is possible to present a map with different layers and symbology depending on the scale of the area of interest. For example, when looking at a map at a small scale, every moraine within a moraine complex is visible, but when viewed at a larger scale the moraine complex is presented as a single object. The digital presentation allows users to select scale-appropriate geomorphological data to their needs. By coupling other SGU or external databases with the geomorphological database it is possible to produce a wide range of products suitable for a wide range of uses. For example, by adding bedrock or geochemical data to landforms indicative of ice flow direction, a product useful for mineral prospecting is created. Other derivative applications may include groundwater studies or evaluation of geoheritage areas. Regarding scientific applications, the new LiDAR data have enabled mapping of geomorphic landforms in greater detail than previous Swedish maps. In addition

    Abrahamsson, Mattias; Kemi, Stig; Lockowandt, Christian; Andersson, Kent

    SSC, formerly known as Swedish Space Corporation, is a Swedish state-owned company working in several different space related fields, including scientific stratospheric balloon launches. Esrange Space Centre (Esrange in short) located in the north of Sweden is the launch facility of SSC, where both sounding rocket launches and stratospheric balloon launches are conducted. At Esrange there are also facilities for satellite communication, including one of the largest civilian satellite data reception stations in the world. Stratospheric balloons have been launched from Esrange since 1974, when the first flights were performed together with the French space agency CNES. These balloon flights have normally flown eastward either only over Sweden or into Finland. Some flights have also had permission to fly into Russia, as far as the Ural Mountains. Normal flight times are from 4 to 12 hours. These eastward flights are conducted during the winter months (September to May). Long duration flights have been flown from ESC since 2005, when NASA flew the BLAST payload from Sweden to north Canada. The prevailing westerly wind pattern is very advantageous for trans-Atlantic flights during summer (late May to late July). The long flight times are very beneficial for astronomical payloads, such as telescopes that need long observation times. In 2013 two such payloads were flown, the first called SUNRISE was a German/US solar telescope, and the other called PoGOLite with a Swedish gamma-ray telescope. In 14 days PoGOLite, which had permission to fly over Russia, made an almost complete circumpolar flight. Typical scientific balloon payload fields include atmospheric research, including research on ozone depletion, astronomical and cosmological research, and research in technical fields such as aerodynamics. University students from all over Europe are involved in flights from Esrange under a Swedish/German programme called BEXUS. Two stratospheric balloons are flown with student

  10. Early retirement pensions in Sweden: trends and regional variations.

    The total number of early retirement pensiones has risen sharply since the end of the 1960s. The increase was greatest during the early 1970s following a reform in 1970 which extended the right to early retirement pension to older workers because of labour market considerations. This article discusses various conceivable explanations for the growth in the number of early retirement pensioners and regional variations of this phenomenon. The following explanatory factors are considered: (a) The prospects of getting (keeping) a job. (b) Work capacity. (c) The nature of the pension scheme. (d) Alternative possibilities of support. (e) Preferences concerning early retirement pensions. The discussion focuses on two explanations highlighted in the public debate in Sweden: changes in pension legislation and the role of the solidarity wages policy. An empirical analysis of variations at the provincial level reveals a definite correlation between the proportion of early retirement pensioners and various indices of unemployment and underemployment.

    Between 2001 and 2006 there was an 'epidemic' of complete withdrawal from daily life among numerous children in refugee families seeking asylum in Sweden. It became embedded in many distinct controversies, including the politics of immigration, and acrimonious disagreements between pediatricians dealing with individual families, and government-employed sociologists commissioned to report on what was going on. Most of the cases resolved themselves when an amnesty was agreed in 2006, although there remain many doubts about the statistics. After describing this phenomenon, the paper proposes a (non-exclusive) model called Imitation & Internalisation. Most of the children may have begun by imitating others who had fallen ill, but soon internalized it to the extent that it became an integral part of their psychophysical and social constitution. The model can be applied to phenomena as diverse as hypnotism, the placebo effect, and catching faith by association with believers (Pascal's wager). PMID:21112004

    There is a range of statistics in Sweden regarding people with functional limitations available from different authorities presenting diverging information. Although healthcare and social welfare legislations aim for equal access and treatment, surveys about unmet needs show that opportunities for rehabilitation are unequal among diagnoses and around the country and insufficient in the long-term. There is also a law granting certain supports and services to those people who are considered to be in need of having someone to speak for them. Disability-related services are tax financed with a symbolic fee. Rehabilitation is performed by not only physical and rehabilitation medicine specialists. Rehabilitation research is mainly within healthcare science but also in social science. Disability services need better coordination, and an agency has recently been founded with this responsibility. More politicians should engage in disability-related issues, and more people with disability should get into politics.

    The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and '60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy. Sweden had advanced plans for a nuclear breeder program, but canceled them in the middle of the 1970s with the rise of nuclear skepticism. The article investigates the nuclear breeder as a technological vision. The nuclear breeder reactor is an example of a technological future that did not meet its industrial expectations. But that does not change the fact that the breeder was an influential technology. Decisions about the contemporary reactors were taken with the idea that in a foreseeable future they would be replaced with the efficient breeder. The article argues that general themes in the history of the breeder reactor can deepen our understanding of the mechanisms behind technological change. PMID:26334698

    2001-12-01

    The four largest Swedish lakes Vänern, Vättern, Mälaren and Hjälmaren all have a tectonic origin with multidirectional fault fissures, which influence the topography of the bottoms and the creation of subbasins. All the four lakes have been subject to several glacials, the latest of which started to recede from central Sweden c. 10,000 years ago. The many differences between the four lakes can be explained by their shapes, sizes and the relation between the sizes of the drainage basins and the size of the lakes. This paper focuses on processes considered relevant to aquatic organisms of the lakes: water balance, water residence time, water temperature, water exchange between subbasins within the lakes, and other internal water movements. Links between pollution, water exchange and retention of nutrients are discussed with an example from Lake Vänern.

    Because of discharges, mainly of lead, from glassworks in an otherwise rural and unpolluted area in southeast Sweden the population became concerned about the potential risks of cancer and an epidemiological study was requested. The total and the specific cancer mortality in the three parishes around the glassworks were found to be approximately normal, both by comparison with national death rates and the death rates of another, similarly rural, area. More interesting results, however, were obtained in several case-referent studies also undertaken to study mortality from specific cancer sites and cardiovascular disease with regard to employment in the glassworks. A significant excess of deaths from stomach cancer, especially in glassblowers, lung cancer, and cardiovascular disease was observed among the glassworkers. Occupational exposures in the glassworks, especially to arsenic, may be of aetiological importance. PMID:4005195

    From national population-based registries linking cancer incidence from 1961 to 1979 with 1960 census data on industry and occupation for all employed individuals in Sweden, a systematic assessment was made of pleural mesothelioma occurrence according to occupational and industrial classifications. There were 318 cases of pleural mesothelioma recorded during the 19-year follow-up period among males employed in 1960, with significant variation by industrial and occupational categorizations. The observed number of pleural mesotheliomas for men employed in the sugar refining, cellulose, wood and pulp, shipbuilding, and railroad equipment manufacturing industries was more than three times the number expected. Occupations with at least twofold excess of mesotheliomas included the craftsman categories of plumbers, mechanics and repairmen, electricians, painters, tire makers, and stationary equipment operators. Our findings are consistent with available data relating mesothelioma to occupational asbestos exposure in other countries, although unexpected associations were found that deserve further epidemiologic study.

    Asbestos exposure in Sweden rapidly grew in the '50s and '60s, and then began to drop at the beginning of the '70s. The number of pleural mesotheliomas due to this exposure increased to some 80 a year during the second half of the '80s, and is rapidly increasing. The jobs with the highest risk are the wood and pulp industry, plumbing, shipbuilding, and, most of all, railroad manufacturing and sugar refineries. Data dealing with peritoneal mesotheliomas are more uncertain, and possibly misleading. As far as lung cancer incidence is concerned, it remains high in plumbers and insulators, while it declined to the expected levels in the other categories of exposed workers.

    The development of Swedish psychiatric legislation is summarized, from the law that came into force on 1 January 1967 to the new law promulgated on 1 January 1992. There are now separate laws for (a) patients who are seriously mentally disturbed and urgently in need of psychiatric hospital care; who oppose care or evidently lack capacity to express a well-grounded opinion as to their needs; and (b) patients sentenced by court to forensic psychiatric care, who have to be seriously mentally disturbed but need not oppose care. As earlier, it seems to be possible to take care of them in general psychiatric wards but special wards for forensic psychiatric care are anticipated. Sweden so far has few such facilities.

    Bergenheim, Asa

    2014-01-01

    After forensic psychiatry was firmly established in Sweden in the 1930s, many rapists and individuals charged with assaulting children underwent a forensic psychiatric examination. The physicians found that most of them had not been "in control" of their senses or not "in complete control" of their senses at the time of the crime. If the court ordered a forensic psychiatric examination, the defendant had a very good chance of either being discharged or having his sentence reduced considerably. By the 1950s psychological perspectives began to dominate in forensic psychiatry. In the forensic records of the 1950s we can notice a shift from a biomedical to a socio-psychological perspective, and crime was increasingly related to conditions that were not seen as mental derangement from a legal point of view. As a result, it became less and less common, from the 1950s onwards, for sentences to be commuted or defendants discharged.

    We examined the association between unintentional nonhunting firearm deaths and changes in firearm legislation in Sweden. There were 43 fatalities during the study time frame 1983-2012, representing 46% of all unintentional firearm deaths during the same period. The victims were predominantly young males (mean age 25 years). Slightly more than half of the deaths were caused by another person and were inflicted at close range. The main cause of the incidents was human error. The majority of the involved firearms were legal; however, most victims killed with illegal firearms were under the influence of alcohol and/or drugs at the time. The death rate decreased significantly following the introduction of the hunter's examination in 1985. Education and training associated with the hunter's examination was at least partially responsible for the decline in fatalities after 1985. Future prevention should target the availability of illegal firearms. PMID:27364274

    The initiative to establish a programme of recurrent education in Sweden arose from a government commission appointed in 1968. The idea received strong support from certain sections of the Swedish trade union movement, who saw it as a way of sharing the benefits of education more equitably among the population. The scheme, however, ran into opposition and was never implemented as a comprehensive strategy. In the 1980s, with the shift of emphasis towards the private sector and the rapid development of information technology, the idea of recurrent education reappeared, although not explicitly acknowledged as official policy. During this period there was a rapid expansion of courses sponsored by employers. Under the present government, recurrent education has ceased to play an important role in education policy. The author argues that these shifts in priorities illustrate how education, and especially adult and recurring education, acts as an arena for ideological struggle.

    2009-12-01

    This article aims to understand how burn-out became an object of thought, through the study of certain processes of legitimization. It traces the genealogy of the burn-out concept from the initial article from 1974, via its confirmation as a "disease" in the 1980s, to its appearance as a legitimate diagnosis in Sweden in 1997. The theoretical framework is that of applied metaphysics, which means a study on how a specific phenomenon came into being. Consequently, I take departure from ontology in motion with an approach that concerns the legitimization processes. The conclusion will show the underlying processes of legitimization in relation to the making of a psychiatric object of thought in Swedish society.

    The aim of this study was to describe the prevalence of creative activities in occupational therapy in Sweden and how often Swedish occupational therapists use creative activities as a means of intervention. A web-mail survey was sent to 2975 Swedish occupational therapists working in health care at regional, county council or primary health care level, and those working in vocational rehabilitation. A total of 1867 (63%) answered the questionnaire and showed that 44% did use creative activities as a means of intervention and most often by practitioners working in psychiatric health care. The most commonly used form of creative activity was arts and crafts followed by gardening. This web-mail survey was based on a limited amount of items regarding creative activities. Further research should focus on in-depth inquiries about how occupational therapists and their patients perceive the use of creative activities as a means of treatment in occupational therapy.

    The Swedish National Seismic Network (SNSN) underwent a rapid expansion and modernization between the years 2000 - 2010. The number of stations increased from 6 to 65, all broadband or semi-broadband with higher than standard sensitivity and all transmitting data in real-time. This has lead to a significant increase in the number of detected earthquakes, with the magnitude of completeness being approximately ML 0.5 within the network. During the last 15 years some 7,300 earthquakes have been detected and located, which can be compared to the approximately 1,800 earthquakes in the Swedish catalog from 1375 to 1999. We have used the recent earthquake catalog and various antropogenic sources (e.g. mine blasts, quarry blasts and infrastructure construction blast) to derive low resolution 3D P- and S-wave velocity models for entire Sweden. Including the blasts provides a more even geographical distribution of sources as well as good constraints on the locations. The resolution of the derived velocity models is in the 20 km range in the well resolved areas. A fairly robust feature observed in the Vp/Vs ratio of the derived models is a difference between the Paleoproterozoic rocks belonging to the TIB (Transscanidinavian Igneous Belt) and the Svecofennian rocks east and north of this region (a Vp/Vs ratio about 1.72 prevail in the former compared to a value below 1.70 in the latter) at depths down to 15 km. All earthquakes occurring since 2000 have been relocated in the 3D velocity model. The results show very clear differences in how earthquakes occur in different parts of Sweden. In the north, north of approximately 64 degrees latitude, most earthquakes occur on or in the vicinity of the Holocene postglacial faults. From 64N to approximately 60N earthquake activity is concentrated along the northeast coast line, with some relation to the offset in the bedrock from the onshore area to the offshore Bay of Bothnia. In southern Sweden earthquake activity is more widely

    On June 27, 1974, the Commission on Sterilization submitted its report entitled "Voluntary Sterilization" to the Ministry of Justice. The present situation in Sweden exists because the original reasons for the law have been found untenable in practice, and the law itself is an obstacle to a sensible application. Consequently, the granting committee is now restricted as a practice which has "to a remarkable degree diverged from the working of the law and the intentions of the legislator" (Report, p. 82). The author illustrates this judgement by reviewing the Board of Health statistics on sterilization between 1935 and 1973, on legal abortion, including sterilizations compulsory for eugenically indicated abortion, and adds some critical comments on the proposals of the Commission.

    Several activities and responsibilities of the Geological Survey of Sweden (SGU) are related to the work of the newly formed international Heritage Stone Task Group (HSTG) for designating historically important stones. SGU is among other things a referral organization, frequently dealing with the preparation of statements in connection with the quarrying permit applications of stone producers. When preparing these statements, SGU takes into account a number of parameters, e.g. the importance for local and regional business development, historic importance, area of occurrence, quality of the geological documentation of the stone type, peculiarities of the stone types and technical properties relevant for the intended use. Traditionally, SGU has not worked with bedrock mapping looking at the potential of natural stones production but more commonly looking at the potential production of aggregates, industrial minerals and metals. The competence is, therefore, presently being built up with new databases over important natural stone types and definition of criteria for their selection etc. In this respect the criteria defined by the HSTG provide important help. This work goes hand in hand with the task of proposing stone-deposits and quarries of "national interest". The criteria for selection of a stone type, quarry etc as one of national interest are currently being revised. SGU plays an important role in this work. However, the final decision and appointment lies in the hands of the Swedish Board of Housing, Building and Planning (Boverket), an authority dealing with sustainable land use and regional development, town and country planning. Boverket supervises how the planning legislation is handled by the municipal authorities and the county administrative boards. The two latter organizations are those in charge of giving extraction permits for stone quarrying. The "Hallandia gneiss", of SW Sweden, is described as a case story and presented in this paper.

    The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing longitudinal twin study targeting all twins born in Sweden since July 1, 1992. Since 2004, parents of twins are interviewed regarding the children's somatic and mental health and social environment in connection with their 9th or 12th birthdays (CATSS-9/12). By January 2010, 8,610 parental interviews concerning 17,220 twins had been completed, with an overall response rate of 80%. At age 15 (CATSS-15) and 18 (CATSS-18), twins and parents complete questionnaires that, in addition to assessments of somatic and mental health, include measures of personality development and psychosocial adaptation. Twin pairs in CATSS-9/12 with one or both twins screening positive for autism spectrum disorders, attention deficit/hyperactivity disorder, tic disorders, developmental coordination disorder, learning disorders, oppositional defiant disorder, conduct disorder, obsessive-compulsive disorder, and/or eating problems have been followed with in-depth questionnaires on family, social environment and personality, and subsequently by clinical assessments at age 15 together with randomly selected population controls, including 195 clinically assessed twin pairs from the first 2 year cohorts (CATSS-15/DOGSS). This article describes the cohorts and study groups, data collection, and measures used. Prevalences, distributions, heritability estimates, ages at onset, and sex differences of mental health problems in the CATSS-9/12, that were analyzed and found to be overall comparable to those of other clinical and epidemiological studies. The CATSS study has the potential of answering important questions on the etiology of childhood mental health problems and their role in the development of later adjustment problems. PMID:22506305

    Objective Diabetes in pregnancy has been shown to increase in parallel with the increasing prevalence of obesity. In this national population-based study, we analyzed the trends for gestational diabetes mellitus (GDM), type 1 diabetes in pregnancy, and type 2 diabetes in pregnancy in Sweden between 1998 and 2012. Research design and methods A population-based cohort study using the Swedish national medical birth registry data. The time periods were categorized into 3-year intervals and adjusted for maternal body mass index (BMI), ethnicity, and age in a logistic regression. Results Each type of diabetes increased over the studied 15-year period. Type 1 diabetes increased by 33.2% (22.2–45.3) and type 2 diabetes by 111% (62.2–174.4) in the adjusted model. Nordic women had the highest prevalence of type 1 diabetes (0·47%) compared with other ethnic groups. The increase in GDM and, to a lesser extent, type 2 diabetes was explained by country of birth, BMI, and maternal age. The prevalence of GDM in Nordic women (0.7–0.8%) did not increase significantly over the time period. Conclusions All types of diabetes in pregnancy increased over the 15-year time period in Sweden. Maternal pre-pregnancy BMI remains the key factor explaining the increase in GDM/type 2 diabetes. How to turn around the growing prevalence of diabetes in pregnancy, with its short-term and long-term health effects on both mother and child, requires population-based interventions that reduce the likelihood of entering pregnancy with a raised BMI.

    Environmental exposures, particularly infection with Epstein-Barr virus (EBV) and tobacco, are known risk factors for oral cancer. Studies in migrants may provide valuable insight into the environmental and genetic etiology of cancer. We wanted to define nasopharyngeal and hypopharyngeal carcinoma among immigrants in Sweden. The nationwide Swedish Family-Cancer Database (FCD) was used to calculate standardized incidence ratios (SIRs) for nasopharyngeal and hypopharyngeal carcinomas among the first-generation immigrants compared to the native Swedes. The FCD included 1969 and 691 cases of nasopharyngeal and hypopharyngeal carcinoma in the male and female Swedes and 178 and 65 cases in immigrants, respectively. The median age at diagnosis (years) was 63 among Swedes and 55 among immigrants. The risk of nasopharyngeal carcinoma was significantly higher in male (SIR = 35.6) and female (24.6) Southeast Asians, male (12.4) and female (34.7) North Africans, male (4.9) and female (10.9) Asian Arabs and some other male Asians immigrants (6.2 to 6.7). Among immigrants from European countries, only the men from former Yugoslavian showed an elevated risk (2.7). Hypopharyngeal carcinoma risk was only increased among the male immigrants from the Indian Subcontinent (5.4). Early life infection with EBV in countries of origin and probably a minor contribution by tobacco smoking may be the main environmental exposures influencing nasopharyngeal carcinoma risks among immigrants to Sweden. The high rates of hypopharyngeal carcinoma among Indian immigrants may point to a continued using of smokeless tobacco.

    OBJECTIVE: We sought to analyse how much of the total burden of disease in Sweden, measured in disability-adjusted life years (DALYs), is a result of inequalities in health between socioeconomic groups. We also sought to determine how this unequal burden is distributed across different disease groups and socioeconomic groups. METHODS: Our analysis used data from the Swedish Burden of Disease Study. We studied all Swedish men and women in three age groups (15-44, 45-64, 65-84) and five major socioeconomic groups. The 18 disease and injury groups that contributed to 65% of the total burden of disease were analysed using attributable fractions and the slope index of inequality and the relative index of inequality. FINDINGS: About 30% of the burden of disease among women and 37% of the burden among men is a differential burden resulting from socioeconomic inequalities in health. A large part of this unequally distributed burden falls on unskilled manual workers. The largest contributors to inequalities in health for women are ischaemic heart disease, depression and neurosis, and stroke. For men, the largest contributors are ischaemic heart disease, alcohol addiction and self-inflicted injuries. CONCLUSION: This is the first study to use socioeconomic differences, measured by socioeconomic position, to assess the burden of disease using DALYs. We found that in Sweden one-third of the burden of the diseases we studied is unequally distributed. Studies of socioeconomic inequalities in the burden of disease that take both mortality and morbidity into account can help policy-makers understand the magnitude of inequalities in health for different disease groups.

    This study analyses the incidence of suicide among children and young people aged between 10 and 29 in Sweden, during the period 1974-1986. The study comprises 4,624 individuals whose deaths were the outcome of verified, E950-E959 (n = 3,511) and undetermined, E980-E989 (n = 1,113) suicides. Regression analysis of different age groups separately and all age groups combined shows that the frequency of suicide among children and young people in Sweden did not increase in this period. Nonetheless, mortality figures are high, especially for boys and young men aged 15-29. The maximum suicide-mortality rate (43.2 per 10,000) is noted for young men aged 25-29 in 1984. The male-female ratio with respect to deaths from suicide is 2.5 for the entire group, the smallest difference being in the 15-19 age group (1.7) and the largest in the 25-29 age group (2.8). Methods of committing suicide vary between the sexes and the various age groups. Boys and young men use violent methods more often, and this situation has remained stable throughout the 13-year period. Girls use non-violent methods to a greater extent, but young women aged 18-29 use violent and non-violent methods to almost the same extent. During the 13-year period studied, a change took place in the girls' and young women's choice of methods towards more violent methods in the 1980s compared with the 1970s. Regardless of sex, there are significantly (p less than 0.001) fewer married and more divorced people among those committing suicide compared with corresponding age groups in the overall population.

    2014-01-01

    Background Uterine cancer (UC) represents 5.1% of all female malignancies in Sweden. Accumulation of UC in families occurs in around 5% of cases. We wanted to identify any familial association between UC and other selected cancers and to study the frequency of Lynch,Cowden and cancer syndromes among consecutive UC patients in Sweden. Methods 481 UC patients were included. Information on the cancer diagnoses of their relatives (first- (FDRs) and second-degree (SDRs) relatives and first cousins) was obtained. The relative frequencies of different cancers among relatives were compared to those in the Swedish general cancer population in 1970 and 2010. Families that fulfilled the criteria for hereditary cancer syndromes were tested for mutations in the causative genes. Families with at least one case of UC in addition to the index patient were compared to families with no additional cases to investigate possible characteristics of putative hereditary cancer syndromes. Results There was an increased prevalence of UC in our study population compared to the Swedish general cancer population in 1970 and 2010 (6% vs. 4% and 3%, respectively). Seven families had Lynch Syndrome according to the Amsterdam II criteria. No families fulfilled the criteria for Cowden syndrome. In total 13% of index patients had at least one relative with UC and these families tended to have more cases of early onset cancer among family members. In addition, 16% of index patients were diagnosed with at least one other cancer. No families fulfilled the criteria for Cowden syndrome. Conclusion We showed a familial clustering of UC among relatives of our index patients. Of the seven families with mutation-verified Lynch Syndrome, only one had been previously diagnosed, highlighting the need to increase gynecologists’ awareness of the importance of taking family history. Our data on multiple cancers and young age of onset in families with uterine cancer is compatible with the existence of additional

    Aim: Our objective was to study the loss of dental attendance and a possible age trend among patients aged ≥65 years in Sweden. Regular dental check-ups are considered to be an important factor in maintaining oral health. Approximately 80% of the adult population in Sweden are enrolled in a regular check-up system; however, dental practitioners often find that older patients attend fewer check-ups. Old people may naturally lose contact with dental services as they move to special housing or die. In this systematic study, these factors were investigated and used as exclusion criteria. Materials and Methods: Data were collected for all patients (n = 4759) aged 65 or older from the electronic journal system in 3 large public dental clinics in 3 communities. Their dental records for the years 2004–2009 were studied longitudinally by 1 person at each clinic; 1111 patients were excluded (patients died during study period, wanted emergency care only, obtained special dental care allowance, moved from the community or moved to special housing, or left the clinic for another caregiver). The statistical analyses were performed using the Statistical Package for the Social Sciences version 21 (IBM). Results: Of the 3648 patients (1690 men and 1958 women) included in the study, 13% lost contact with their dental service over the course of the study (10% of those were aged 65–79 and 21% ≥80). The decrease in regular dental contact had a statistically significant association with increasing age (P < 0.001). Conclusion: A considerable number of older people living independently or with moderate supportive care in their own homes lost contact with dental service despite enrolment in a recall system.

  19. Nutrient trends through time in Sweden's Baltic Drainage Area

    Changes in climate and land-use have and will continue to modify regional hydrology, in turn impacting environmental health, agricultural productivity and water resource quality and availability. The Baltic region is an area of interest as the coast spans nine countries- serving over 100 million people. The Baltic Sea contains one of the largest human caused hypoxic dead zones due to eutrophication driven by anthropogenic excess loading of nutrients. Policies to reduce these loads include also international directives and agreements, such as the EU Water Framework Directive, adopted in 2000 to protect and improve water quality throughout the European Union, and the Baltic Sea Action Plan under the Helsinki Commission aimed specifically at reducing the nutrient loading to and mitigating the eutrophication of the Baltic Sea. In light of these policies and amidst the number of studies on the Baltic Sea we ask, using the accessible nutrient and discharge data what does nutrient loading look like today? Are the most excessive loads going down? Observed nutrient and flow time series across Sweden allow for answering these questions, by spatial and temporal trend analysis of loads from various parts of Sweden to the Baltic Sea. Analyzing these observed time series in conjunction with the ecological health status classifications of the EU Water Framework Directive, allows in particular for answering the question if the loads into the water bodies with the poorest water quality, and from those to the Baltic Sea, are improving, being maintained or deteriorating. Such insight is required to contribute to relevant and efficient water and nutrient load management. Furthermore, empirically calculating nutrient loads, rather than only modeling, reveals that the water body health classification may not reflect what water bodies actually contribute the heaviest loads to the Baltic Sea. This work also underscores the importance of comprehensive analysis of all available data from

  20. Undoing Gender Through Legislation and Schooling: the Case of AB 537 and AB 394 IN California, USA

    2009-11-01

    This article investigates California laws AB 537: The Student Safety and Violence Prevention Act of 2000, and the recently enacted AB 394: Safe Place to Learn Act. Both demand that gender identity and sexual orientation be added to the lexicon of anti-harassment protection in public education. However, despite these progressive measures, schools have an unconscious acceptance of heteronormativity and gendered norms, which undermines both the spirit and language of these laws. This paper examines how California schools can both change standard practices and realise the transformative social change that laws like AB 537 and AB 394 can instigate. I assert that the systemic implementation of these laws, through the adoption, enforcement and evaluation of existing AB 537 Task Force Recommendations, is necessary for their success. My second assertion is that AB 537 and AB 394 have the potential to change and reconstitute gender-based and heteronormative standards at school sites.

  4. Ab initio melting curve of osmium

    2015-11-01

    The melting curve of osmium up to a pressure P of 500 GPa is obtained from an extensive suite of ab initio quantum molecular dynamics (QMD) simulations using the Z method. The ab initio P =0 melting point of Os is 3370 ±75 K; this range encompasses all of the available data in the literature and corroborates the conclusion of J. W. Arblaster [Platinum Metals Rev. 49, 166 (2005)], 10.1595/147106705X70264 that the melting temperature of pure Os is 3400 ±50 K and that the 3300 K typically quoted in the literature is the melting point of impure Os. The T =0 equation of state (EOS) of Os and the P dependence of the optimized c /a ratio for the hexagonal unit cell, both to pressures ˜900 GPa, are obtained in the ab initio approach as validation of its use. Although excellent agreement with the available experimental data (P ≲80 GPa) is found, it is the third-order Birch-Murnaghan EOS with B0'=5 rather than the more widely accepted B0'=4 that describes the QMD data to higher pressures, in agreement with the more recent experimental EOS by Godwal et al. The theoretical melting curve of Os obtained earlier by Joshi et al. is shown to be inconsistent with our QMD results, and the possible reason for this discrepancy is suggested. Regularities in the melting curves of Os and five other third-row transition metals (Ta, W, Re, Pt, Au) could be used to estimate the currently unknown melting curves of Hf and Ir.

    Polybrominated diphenyl ethers (PBDEs) were the first brominated persistent organic pollutants (POPs) listed in the Stockholm Convention. Parties to the convention are currently establishing inventories for developing action plans for the environmentally sound management of PBDE-containing materials. The major use of commercial octabromodiphenyl ether (c-OctaBDE) has been in casings from cathode ray tube (CRT) TVs and computer monitors. Large quantities of used e-waste and electronic equipment have been exported to developing countries with Nigeria being a major importer in Africa. The casings from 382 TVs and computers imported from major world regions to Nigeria were sampled in backyards and waste dumps. The samples were screened with X-ray flourescence (XRF) for bromine and analysed by gas chromatography/ electron capture detection (GC/ECD) for brominated flame retardants (BFRs). A high proportion of the CRT casings (61 %) contained more than 10,000 ppm bromine from BFRs. Decabromodiphenyl ether (DecaBDE) was the major flame retardant used in TV sets and tetrabromobisphenol A (TBBPA) for computer CRTs.The screening suggests that average PBDE levels (of c-OctaBDE + DecaBDE) in Nigerian-stockpiled CRT casings were 1.1 % for TV and 0.13 % for PC CRTs. These are above the Restriction of Hazardous Substances (RoHS) limit and should be separated for RoHS compliant recycling. The Nigerian e-waste inventory of 237,000 t of CRT plastic would therefore contain approx. 594 t c-OctaBDE and 1,880 t of DecaBDE. In Nigeria, as for most developing countries, there is currently no adequate e-waste management, plastic separation or destruction capacity. The data highlight the urgent need to develop environmentally sound management for this large material flow.

    The aim was to present and evaluate the impact of a comprehensive strategy over 10 years to select, communicate and achieve adherence to essential drug recommendations (EDR) in ambulatory care in a metropolitan healthcare region. EDRs were issued and launched as a 'Wise List' by the regional Drug and Therapeutics Committee in Stockholm. This study presents the concept by: (i) documenting the process for selecting, communicating and monitoring the impact of the 'Wise List'; (ii) analysing the variation in the number of drug substances recommended between 2000 and 2010; (iii) assessing the attitudes to the 'Wise List' among prescribers and the public; (iv) evaluating the adherence to recommendations between 2003 and 2009. The 'Wise List' consistently contained 200 drug substances for treating common diseases. The drugs were selected based on their efficacy, safety, suitability and cost-effectiveness. The 'Wise List' was known among one-third of a surveyed sample of the public in 2002 after initial marketing campaigns. All surveyed prescribers knew about the concept and 81% found the recommendations trustworthy in 2005. Adherence to recommendations increased from 69% in 1999 to 77% in 2009. In primary care, adherence increased from 83% to 87% from 2003 to 2009. The coefficient of variation (CV%) decreased from 6.1% to 3.8% for 156 healthcare centres between these years. The acceptance of the 'Wise List' in terms of trust among physicians and among the public and increased adherence may be explained by clear criteria for drug recommendations, a comprehensive communication strategy, electronic access to recommendations, continuous medical education and involvement of professional networks and patients.

    The central problem in the determination of protein structures form x-ray diffraction dada (x-ray crystallography) corresponds to a phase retrieval problem with undersampled amplitude data. Algorithms for this problem that have an increased radius of convergence have the potential for reducing the amount of experimental work, and cost, involved in determining protein structures. We describe such an algorithm. Application of the algorithm to a simulated crystallographic problem shows that it converges to the correct solution, with no initial phase information, where currently used algorithms fail. The results lend support to the possibility of ab initio phasing in protein crystallography.

    The paper deals with the problem of adapting software implemented fault injection technique (SWIFI) to evaluate dependability of reactive microcontroller systems. We present an original methodology of disturbing controller operation and analyzing fault effects taking into account reactions of the controlled object and the impact of the system environment. Faults can be injected randomly (in space and time) or targeted at the most sensitive elements of the controller to check it at high stresses. This approach allows identifying rarely encountered problems, usually missed in classical approaches. The developed methodology has been used successfully to verify dependability of ABS system. Experimental results are commented in the paper.

    Sideropenic anemia with epithelial lesions (Plummer-Vinson syndrome) was previously very common among women in northern Sweden. The incidence of this condition is decreasing, however, because of better nutrition and improved health care. Plummer-Vinson syndrome as a sequela of previous sideropenic anemia still influences the pattern of hypopharyngeal and oral cancer in northern Sweden where the female/male ratio in these diseases is remarkably high and where cancer in the postcricoid part of the hypopharynx is relatively common. In Sweden as a whole, a decreasing trend in the incidence of hypopharyngeal cancer in women can be demonstrated, which is probably due to diminished prevalence of Plummer-Vinson syndrome.

  12. New challenges to medicare beneficiary access to mAbs

    2009-01-01

    Precision binding of monoclonal antibodies (mAbs) to biological targets, their relative clinical success, and expansion of indications following initial approval, are distinctive clinical features. The relatively high cost of mAbs, together with the absence of a regulatory pathway to generics, stand out as distinctive economic features. Based on both literature review and primary data collection we enumerated mAb original approvals, supplemental indications and off-label uses, assessed payer formulary management of mAbs, and determined new challenges to Medicare beneficiary access to mAbs. We found that the FDA has approved 22 mAbs and 30 supplemental indications pertaining to the originally approved mAbs. In addition, there are 46 off-label use citations in officially recognized pharmaceutical compendia. Across Part B carriers and Part D plans, we found considerable variation in terms of coverage and conditions of reimbursement related to on- and off-label uses of mAbs. Our results point to four major challenges facing mAb developers, health care providers, Medicare beneficiaries, payers and policymakers. These include administrative price controls, coverage variation, projected shift from physician- to self-administered mAbs, and comparative effectiveness. We suggest more systematic use of “coverage with evidence development” as a means of optimally addressing these challenges. PMID:20046575

    On the basis of highly correlated ab initio calculations, an accurate determination of the electronic structure and of the rovibrational spectroscopy has been performed for the electronic ground state of the HZnF system. Using effective core pseudopotentials for the Zn and F atoms and associated aug-cc-pVQZ basis sets, we have calculated, at the multireference configuration interaction level including the Davidson correction, the three-dimensional potential energy surface of the X1Σ+ ground state. The rovibrational energy levels have been obtained variationally, and the results have been discussed and compared with existing experimental data on the ground state of the close system HZnCl, which exhibits a complicated vibration-rotation spectrum. Our analysis shows that the nature of the H-ZnF bond is quite similar to that of the H-ZnCl bond, according to their bond lengths, harmonic frequencies of the H-Zn stretching mode, and dissociation energies into H and ZnF/ZnCl. The ab initio study of the electronic ground and excited states of ZnH and ZnH+ are also presented using similar level of calculations. Characteristic constants are given for the first bounded electronic states correlating to the first two dissociation asymptotes of the neutral and ionic diatomics.

    Anti-lock braking system (ABS) braking tests with two subcompact passenger cars were performed on dry and wet asphalt, as well as on snow and ice surfaces. The operating conditions of the tyres in terms of wheel slip were evaluated using histograms of the wheel slip data. The results showed different average slip levels for different road surfaces. It was also found that changes in the tyre tread stiffness affected the slip operating range through a modification of the slip value at which the maximum longitudinal force is achieved. Variation of the tyre footprint length through modifications in the inflation pressure affected the slip operating range as well. Differences in the slip distribution between vehicles with different brake controllers were also observed. The changes in slip operating range in turn modified the relative local sliding speeds between the tyre and the road. The results highlight the importance of the ABS controller's ability to adapt to changing slip-force characteristics of tyres and provide estimates of the magnitude of the effects of different tyre and road operating conditions.

    Many magnetic materials do not conform to the (anti-)ferromagnetic paradigm where all electronic spins are aligned to a global magnetization axis. Unfortunately, most electronic structure methods cannot describe such materials with noncollinear electron spin on account of formally requiring spin alignment. To overcome this limitation, it is necessary to generalize electronic structure methods and allow each electron spin to rotate freely. Here, we report the development of an ab initio time-dependent non-relativistic two-component spinor (TDN2C), which is a generalization of the time-dependent Hartree-Fock equations. Propagating the TDN2C equations in the time domain allows for the first-principles description of spin dynamics. A numerical tool based on the Hirshfeld partitioning scheme is developed to analyze the time-dependent spin magnetization. In this work, we also introduce the coupling between electron spin and a homogenous magnetic field into the TDN2C framework to simulate the response of the electronic spin degrees of freedom to an external magnetic field. This is illustrated for several model systems, including the spin-frustrated Li{sub 3} molecule. Exact agreement is found between numerical and analytic results for Larmor precession of hydrogen and lithium atoms. The TDN2C method paves the way for the ab initio description of molecular spin transport and spintronics in the time domain.

    2016-02-01

    A fermionic chain is a one-dimensional system with fermions that interact locally and can jump between sites in the lattice, in particular an AB n chain type, where A and B are sites that exhibit a difference in energy level of Δ and site B is repeated n-times, such that the unit cell has n +1 sites. A limit case of this model, called the ionic Hubbard model (n = 1), has been widely studied due to its interesting physics and applications. In this paper, we study the ground state of an AB 2 chain, which describes the material R 4[Pt 2(P 2O5H2)4X] · nH 2 O. Specifically, we consider a filling with two electrons per unit cell, and using the density matrix renormalization group method we found that the system exhibits the band insulator and Mott correlated insulator phases, as well as an intermediate phase between them. For couplings of Δ = 2,10 and 20, we estimate the critical points that separate these phases through the structure factor and the energy gap in the sector of charge and spin, finding that the position of the critical point rises as a function of Δ.

    In this study, the biosorption of Acid Blue 290 and Acid Blue 324 on Spirogyra rhizopus, a green algae growing on fresh water, was studied with respect to initial pH, temperature, initial dye concentration and biosorbent concentration. The optimum initial pH and temperature values for AB 290 and AB 324 biosorption were found to be 2.0, 30 degrees C and 3.0, 25 degrees C, respectively. It was observed that the adsorbed AB 290 and AB 324 amounts increased with increasing the initial dye concentration up to 1500 and 750 mg/L, respectively. The Langmuir, Freundlich, Redlich-Peterson and Koble-Corrigan isotherm models were applied to the experimental equilibrium data and the isotherm constants were determined by using Polymath 4.1 software. The monolayer coverage capacities of S. rhizopus for AB 290 and AB 324 dyes were found as 1356.6 mg/g and 367.0 mg/g, respectively. The intraparticle diffusion model and the pseudo-second order kinetic model were applied to the experimental data in order to describe the removal mechanism of these acidic dyes by S. rhizopus. The pseudo-second order kinetic model described very well the biosorption kinetics of AB 290 and AB 324 dyes. Thermodynamic studies showed that the biosorption of AB 290 and AB 324 on S. rhizopus was exothermic in nature.

    AB5 toxins are important virulence factors for several major bacterial pathogens, including Bordetella pertussis, Vibrio cholerae, Shigella dysenteriae and at least two distinct pathotypes of Escherichia coli. The AB5 toxins are so termed because they comprise a catalytic A-subunit, which is responsible for disruption of essential host functions, and a pentameric B-subunit that binds to specific glycan receptors on the target cell surface. The molecular mechanisms by which these AB5 toxins cause disease have been largely unraveled, including recent insights into a novel AB5 toxin family, subtilase cytotoxin (SubAB). Furthermore, AB5 toxins have become a valuable tool for studying fundamental cellular functions, and are now being investigated for potential applications in the clinical treatment of human diseases.

    Trends were found for increasing surface ozone concentrations during April-September in northern Sweden over the period 1990-2006 as well as for an earlier onset of vegetation growing season. The highest ozone concentrations in northern Sweden occurred in April and the ozone concentrations in April showed a strong increasing trend. A model simulation of ozone flux for Norway spruce indicated that the provisional ozone flux based critical level for forests in Europe is exceeded in northern Sweden. Future climate change would have counteracting effects on the stomatal conductance and needle ozone uptake, mediated on the one hand by direct effect of increasing air temperatures and on the other through increasing water vapour pressure difference between the needles and air. Thus, there is a substantial and increasing risk for negative impacts of ozone on vegetation in northern Sweden, related mainly to increasing ozone concentrations and an earlier onset of the growing season.

    There is an increased awareness that medicinal products for human use may cause negative effects in the environment. In Sweden a voluntary environmental classification system for drugs has been established in collaboration between producers, authorities and the public health care, and used for five years. The idea is to enhance the market demand for medicines with less environmental impact, which in turn will stimulate the producers to design future medicines to be more environmentally friendly. The system is open to the public and based on assessment of the active ingredient in the medicinal product into several classes of risk and hazard, respectively. It is closely related to the EMEA guidelines. Risk is expressed as the ratio between the predicted environmental concentration (PEC) of the active ingredient (AI) and its predicted no effect concentration (PNEC). The hazard is expressed in terms of the AI's persistence, potential to bioaccumulation, and eco-toxicity. Drug data for the classification are delivered by the respective producers. Hitherto more than 300 AI, representing more than 50% of the Swedish volume of drug use, have been classified. Data for risk assessment were missing in 47% of AI. Among drugs with data 7% had a PEC/PNEC ratio >1, and another 7% had a ratio between 0.1 and 1. The AIs with highest ratio (>10) were two estrogens. Data for hazard assessment were lacking in 16% of the AI. Among drugs with environmental data 92% were not ready biodegradable, 23% had potential to bioaccumulation, and 61% were toxic to aquatic organisms at a concentration below 1 mg/l. These data are utilized by regional pharmaceutical expert groups when selecting substances to be recommended in public health care in Sweden. They may also be used by prescribing doctors who want to identify the environmentally most favourable substance among several with equivalent medical effect. We conclude that environmental data on human medicinal products are often missing, or

    Background Elderly injuries are a recognized public health concern and are due to two factors; osteoporosis and accidental falls. Several osteoporosis pharmaceuticals are considered cost-effective, but intervention programs aiming at preventing falls should also be subjected to economic evaluations. This study presents a cost-effectiveness analysis of a community-based elderly safety promotion program. Methods A five-year elderly safety promotion program combining environmental structural changes with individually based measures was implemented in a community in the metropolitan area of Stockholm, Sweden. The community had around 5,500 inhabitants aged 65+ years and a first hip fracture incidence of 10.7 per 1,000 in pre-intervention years 1990–1995. The intervention outcome was measured as avoided hip fractures, obtained from a register-based quasi-experimental longitudinal analysis with several control areas. The long-term consequences in societal costs and health effects due to the avoided hip fractures, conservatively assumed to be avoided for one year, were estimated with a Markov model based on Swedish data. The analysis holds the societal perspective and conforms to recommendations for pharmaceutical cost-effectiveness analyses. Results Total societal intervention costs amounted to 6.45 million SEK (in Swedish krona 2004; 1 Euro = 9.13 SEK). The number of avoided hip fractures during the six-year post-intervention period was estimated to 14 (0.44 per 1,000 person-years). The Markov model estimated a difference in societal costs between an individual that experiences a first year hip fracture and an individual that avoids a first year hip fracture ranging from 280,000 to 550,000 SEK, and between 1.1 and 3.2 QALYs (quality-adjusted life-years, discounted 3%), for males and females aged 65–79 years and 80+ years. The cost-effectiveness analysis resulted in zero net costs and a gain of 35 QALYs, and the do-nothing alternative was thus dominated. Conclusion

    Tumor-specific monoclonal antibodies (mAbs) have demonstrated efficacy in the clinic, becoming an important approach for cancer immunotherapy. Due to its limited expression on normal tissue, the GD2 disialogangloside expressed on neuroblastoma cells is an excellent candidate for mAb therapy. In 2015, dinutuximab (an anti-GD2 mAb) was approved by the US FDA and is currently used in a combination immunotherapeutic regimen for the treatment of children with high-risk neuroblastoma. Here, we review the extensive preclinical and clinical development of anti-GD2 mAbs and the different mechanisms by which they mediate tumor cell killing. In addition, we discuss different mAb-based strategies that capitalize on the targeting ability of anti-GD2 mAbs to potentially deliver, as monotherapy, or in combination with other treatments, improved antitumor efficacy.

    Infants with a clinical diagnosis of anophthalmia or microphthalmia were identified from four health registers in Sweden, covering different parts of the period 1965-2001. During the observation period, the rate of anophthalmia decreased from the early 1970s from 0.4 to 0.2 per 10,000 births. The registered rate of microphthalmia increased markedly during the observation period to reach a maximum in 1987 of about 1.5 per 10,000. About 10% of the 432 identified children had a chromosome anomaly. There was no geographical variation in prevalence and infants born in urban or rural districts had, if anything, a lower risk than infants born in cities (0.93 and 1.13 per 10,000, respectively). Non-eye malformations were more common at anophthalmia (63%) than at microphthalmia (30%). Sex ratio was normal and no statistically significant variation between sub-groups (anophthalmia, microphthalmia, isolated, associated with non-eye malformations) could be demonstrated. There was a marked risk increase with maternal age but no certain parity effect, no effect of maternal education, but a possible association with subfertility. Maternal smoking in early pregnancy seemed to increase the risk for anophthalmia or microphthalmia in the absence of a coloboma.

    Microsporidia are spore-forming intracellular parasites that infrequently cause disease in immunocompetent persons. This study describes the first report of a foodborne microsporidiosis outbreak which affected persons visiting a hotel in Sweden. Enterocytozoon bieneusi was identified in stool samples from 7/11 case-patients, all six sequenced samples were genotype C. To confirm that this was not a chance finding, 19 stool samples submitted by healthy persons from a comparable group who did not visit the hotel on that day were tested; all were negative for microsporidia. A retrospective cohort study identified 135 case-patients (attack rate 30%). The median incubation period was 9 days. Consumption of cheese sandwiches [relative risk (RR) 4·1, 95% confidence interval (CI) 1·4-12·2] and salad (RR 2·1, 95% CI 1·1-4) were associated with illness. Both items contained pre-washed, ready-to-eat cucumber slices. Microsporidia may be an under-reported cause of gastrointestinal outbreaks; we recommend that microsporidia be explored as potential causative agents in food- and waterborne outbreaks, especially when no other organisms are identified.

    The paper examines the conceptual context of cultural diversity in Sweden. It describes the background in which the former Social Democratic Government declared 2006 as the Year for Cultural Diversity. A related concern is scrutinizing whether in fact this year would be a starting point for more deeply engaged diversity programs or if such policy definitions remain mere symbolic acts of window dressing. The study is based on analysis of official documents, diversity events and agendas, and interviews with different actors and diversity consultants, and participation in seminars and conferences on the topic of diversity and integration as the main topics. A major concern is whether the current interest on cultural diversity may lead to its institutionalization in the Swedish cultural and social organizations (Hamde, 2002a) and address the virtues of diversity, such as diversity for profitability and competence in workplaces, social justice concerns, and finally, societal cohesion. Alternatively, the paper explores if the debate on diversity merely remains a 'traveling' idea to appear occasionally and then occur in fashion-like manner as many management ideas do, leaving little traces on peoples' lives.

    Treatment of solid waste continues to be on the political agenda. Waste disposal issues are often viewed from an environmental perspective, but economic and social aspects also need to be considered when deciding on waste strategies and policy instruments. The aim of this paper is to suggest flexible and robust strategies for waste management in Sweden, and to discuss different policy instruments. Emphasis is on environmental aspects, but social and economic aspects are also considered. The results show that most waste treatment methods have a role to play in a robust and flexible integrated waste management system, and that the waste hierarchy is valid as a rule of thumb from an environmental perspective. A review of social aspects shows that there is a general willingness among people to source separate wastes. A package of policy instruments can include landfill tax, an incineration tax which is differentiated with respect to the content of fossil fuels and a weight based incineration tax, as well as support to the use of biogas and recycled materials.

    Methane emissions from Stordalen Mire in subarctic Sweden have been increasing over the last century with rising atmospheric temperatures. Methane emissions from lakes in this region have shown a positive correlation with sediment and air temperatures. Previous studies have examined CH4 emissions of these lakes but the primary stream that flows along the edge the mire is understudied. Streams and rivers that exist in permafrost peatland environments are thought to be a pathway for the release of older carbon deposits from thawing permafrost. To understand the potential role of stream morphology and stratigraphy on CH4 concentrations and contributions to carbon cycling in this system, seven sediment cores were extracted from the stream and one from the adjacent lake. Cores were subsampled at 5cm depth intervals and analyzed for CH4 concentration, δ13CH4 isotopes, elemental CHNS and sediment grain size. Results from these analyses show that maximum CH4 concentrations in stream sediments occur at greater depths than in the adjacent lake sediments. Higher CH4 concentrations are observed in organic C rich layers in both environments. However, in stream sediments, CH4 appears to be produced within some stratigraphic intervals, but exists in others as the result of transport. Organic C/N ratios of the sediments indicate a predominance of terrestrial organic C but it is unclear whether the sediment organic C is the result of deposition of C from permafrost thaw or C that was deposited through the degradation of modern plant material.

    During the 1960s uranium was extracted from alum shale deposits at Ranstad in the south of Sweden. This mine was part of the development of a Swedish nuclear power program based on the heavy-water/natural uranium concept. In this report the history of Swedish uranium production is briefly presented as well as the reason for the closing-down of the mine at Ranstad. In 1985 the planning of the restoration of the area started. The aim of the remediation work was to find a permanent solution that excluded the need for any maintenance in the future. The procedures and techniques for remedial action are described for the open pit mine and the mill tailing deposits. As the leachate from the mill tailings was collected and purified, there was no urgent need for action. Investigations could be made to find an effective way for reducing the weathering of the pyrite in the tailings and the authorities concerned could accept the remediation plan after a detailed review. The main part of the plan has now been implemented and many experiences from the performance technique and the significant quality assurance program have been obtained. The old open pit mine has already been transformed into a lake and the mill tailings are covered by a leaktight barrier and a protective layer. The natural environment in the whole area has been reestablished.

    Subjective feelings of risk are a central feature of everyday life, and evidence shows that people who do not conform to contemporary normative notions are often more exposed to everyday risks than others. Despite this, normative notions are rarely acknowledged as risk objects. By drawing on the theory of 'doing' and 'undoing' risk, which combines intersectional and risk theory, this study contributes new perspectives on the everyday risks in contemporary society that face people who many would label as being 'at risk' - lesbian, gay, bisexual and transgender people. The study consists of five focus group interviews with lesbian, gay, bisexual and transgender people of different ages in Sweden. Findings pinpoint risks and how these are done and un-done in different spheres of interviewees' lives: the emotional risks prevailing in their private lives; the risk of discrimination at work and in relations with other institutions; and the risk of violence and harassment in public places. These risks are all related to the heteronormative order in which the mere fact of being lesbian, gay, bisexual and transgender is perceived as a risk. PMID:26242996

    This paper describes the introduction of alcopops and sweet ciders in Sweden in 1996, as a result of the membership of the European Union. Special attention is given to its effect on youth drinking. Surveys of young people show that alcopops and sweet ciders are perceived to be easy to drink and to have a sweet and pleasant taste, which tends to conceal the taste of alcohol. These results suggest that alcopops and sweet ciders should be regarded as one category of drinks. Alcopops and sweet ciders have penetrated the youth market rapidly. The introduction of these beverages accounted for approximately half of the increase in alcohol consumption by 15-16-year-old boys from 1996 to 1999, and two-thirds of the increase among girls, according to the surveys. A large proportion of the youth answered that alcopops and ciders did not replace any other alcoholic beverage. The paper also describes the public debate on alcopops and cider. The introduction of alcopops was criticized by the media and the responsible minister. Prominent spokesmen of the alcohol industry put themselves at a distance from these, primarily imported, products. The sales of alcopops have been declining since 1997. Sweet ciders, on the other hand, which in reality are synonymous with alcopops, have continued to increase during the whole period since 1996, and have not been subject to the same public criticism.

    Emissions from petrochemical industries may contain suspected or established carcinogens. As increased incidence of cancer in residential areas close to petrochemical industries has been reported in the literature, we conducted a study of cancer incidence in Stenungsund, Sweden, where petrochemical industries were established in the mid 1960s. A number of cancer cases in the central parts of Stenungsund were collected from the regional cancer registry for each year between 1974 and 2005. In addition to the total number of cases, the numbers of leukemia, lymphoma, liver cancer, lung cancer, and brain cancer were also collected. Expected numbers for each year were calculated based on age- and sex-specific incidence rates in reference areas. Levels of carcinogenic volatile hydrocarbons (VOC) were estimated from measurements and emission data. A dispersion model was used to classify Stenungsund into a "low" and "high" ethylene level area. Standardized Incidence Ratio (SIR) for all cancer for the entire period was 1.02 (95% CI 0.97-1.08). The occurrence of leukemia, lymphoma, and cancer in the central nervous system was slightly lower than expected for the entire period. SIR for lung cancer was 1.37 (95% CI 1.10-1.69), and SIR for liver cancer was 1.50 (0.82-2.53). VOC levels were low. Taking estimated exposure and demographic factors into account, our assessment is that occurrence of cancer was not affected by industrial emissions in any of the studied sites.

    Several genetic studies have demonstrated an association between mutations in glucocerebrosidase (GBA), originally implicated in Gaucher's disease, and an increased risk of Parkinson's disease (PD). We have investigated the possible involvement of genetic GBA variations in PD in the Swedish population. Three GBA variants, E326K, N370S, and L444P were screened in the largest Swedish Parkinson cohort reported to date; 1625 cases and 2025 control individuals. We found a significant association with high effect size of the rare variant L444P with PD (odds ratio 8.17; 95% confidence interval: 2.51-26.23; p-value = 0.0020) and a significant association of the common variant E326K (odds ratio 1.60; 95% confidence interval: 1.16-2.22; p-value = 0.026). The rare variant N370S showed a trend for association. Most L444P carriers (68%) were found to reside in northern Sweden, which is consistent with a higher prevalence of Gaucher's disease in this part of the country. Our findings support the role of GBA mutations as risk factors for PD and point to lysosomal dysfunction as a mechanism contributing to PD etiology. PMID:27255555

  20. Effects of Compulsory Schooling on Mortality: Evidence from Sweden

    2013-01-01

    Theoretically, there are several reasons to expect education to have a positive effect on health. Empirical research suggests that education can be an important health determinant. However, it has not yet been established whether education and health are indeed causally related, and the effects found in previous studies may be partially attributable to methodological weaknesses. Moreover, existing evidence on the education-health relationship generally uses information of fairly recent schooling reforms, implying that health outcomes are observed only over a limited time period. This paper examines the effect of education on mortality using information on a national roll-out of a reform leading to one extra year of compulsory schooling in Sweden. In 1936, the national government made a seventh school year compulsory; however, the implementation was decided at the school district level, and the reform was implemented over 12 years. Taking advantage of the variation in the timing of the implementation across school districts, by using county-level proportions of reformed districts, census data and administrative mortality data, we find that the extra compulsory school year reduced mortality. In fact, the mortality reduction is discernible already before the age of 30 and then grows in magnitude until the age of 55–60. PMID:23945539

    The growing season is changing in both ends and autumn phases seem to be responding in more diverse ways than spring events. Indeed, we know little about autumn leaf phenological strategies and how they are correlated with fitness components or ecosystem properties, and how they vary between species and over bioclimatic gradients. In this study more than 10 000 students were involved in observing autumn leaf development at 378 sites all over Sweden (55-68°N). They followed an image based observation protocol classifying autumn leaf development into five levels, from summer green (level 0) to 100% autumn leaf colored (level 4) canopy. In total, they submitted almost 12 000 observations between August 9 and November 15. 75% of the observations were made on the common species of Populus tremula, Betula pendula/pubescens and Sorbus aucuparia. The expected (negative) correlation between latitude and start of leaf senescence (level 2) was found in Populus and Betula, but not in Sorbus. The duration of the leaf senescence period, defined as the period between 1/3 (level 2) and 100% (level 4) of the canopy autumn leaf colored, was negatively correlated with latitude in Populus and Betula, but not in Sorbus. There was also a strong (negative) correlation of the start (level 2) and the duration of the leaf senescence in the early senescing Sorbus and Betula, while this effect was weaker in the late senescing Populus.

    2009-03-01

    Airborne VLF data are routinely collected by The Geological Survey of Sweden (SGU) as part of its bedrock mapping programme. In this paper we demonstrate that the novel Tensor VLF technique developed at Uppsala University and SGU can provide useful qualitative and quantitative information about the electrical conductivity distribution in the upper few hundred meters. Single transmitter scalar VLF maps emphasize those conductive structures that have dominant strikes in the direction of the transmitter. The tensor tipper (essentially the vertical magnetic field from currents along the strike direction) calculated from multiple transmitters is dependent only upon the underlying conductivity structure. Transformation of the tipper into the peaker (the horizontal divergence) has proven to enhance the lateral resolution while the transformation to the apparent resistivity can be used to discriminate different rock types. Two case histories from the application of VLF data are presented in this study. Two dimensional structures can be quantitatively modelled by modern inversion methods developed originally for deep electromagnetic MT soundings. Direct inversion of the real and imaginary parts of the tipper provides more quantitative information about the subsurface resistivity distribution.

    The transport of marine aerosols across southern Sweden was studied using six meteorological stations in a transect from west- to east-coast. Measurements were made during dry westerlies on 10 occasions during 1995. The concentration and flux of salt in the air was measured using "salt vanes". It is concluded that marine salt is transported along the whole transect at all occasions and that the concentration and flux of salt decrease with downwind distance from the coast as an inversed power function. The two easternmost stations show a slight increase towards the east-coast. Variability of the data is high on the west coast due to strong influence from the coastal production of aerosols. This effect diminishes along downwind forming lower, less variable concentration further inland. Statistical models based on the data are in relatively good agreement with previous models and data. Further, salt content on Scots Pine ( Pinus sylvestris, L) needles after two westerly gale occasions, in profiles from west- to east-coast, were analysed. The Cl -/Na +, Ca 2+/Na +, K +/Na +, Mg 2+/Na + and SO 42-/Na + ratios were studied revealing a clear downwind decrease in Ca 2+/Na + and Mg 2+/Na +, a close to sea water ratio for Cl -/Na + and an excess of SO 42- along the profile. Also, the importance of degree of exposure was studied concluding that the roughness of the upwind surface is an important factor for the deposition onto trees in forest edges.

    Treatment of solid waste continues to be on the political agenda. Waste disposal issues are often viewed from an environmental perspective, but economic and social aspects also need to be considered when deciding on waste strategies and policy instruments. The aim of this paper is to suggest flexible and robust strategies for waste management in Sweden, and to discuss different policy instruments. Emphasis is on environmental aspects, but social and economic aspects are also considered. The results show that most waste treatment methods have a role to play in a robust and flexible integrated waste management system, and that the waste hierarchy is valid as a rule of thumb from an environmental perspective. A review of social aspects shows that there is a general willingness among people to source separate wastes. A package of policy instruments can include landfill tax, an incineration tax which is differentiated with respect to the content of fossil fuels and a weight based incineration tax, as well as support to the use of biogas and recycled materials.

    The Macropermeability Experiment was conducted in a granite body adjacent to a recently abandoned iron ore mine at Stripa, Sweden. This experiment was conducted to measure the permeability of a large volume of low permeability, fractured rock. The experiment was conducted over 11 months in an approximately 4m x 4m x 33m drift at the 335 m level of the mine. Groundwater seepage into the drift was measured as the net moisture pickup of the ventilation system. Water pressure and temperature were monitored at 95 locations in the rock surrounding the drift. The data collection system was designed to provide in-situ averaging of the measured parameters, to ultimately estimate the hydraulic conductivity of the rock as if it were a porous medium. This report is limited to data presentation. It describes the types of data collected, the methods of measurement, and procedures used for data collection, storage, and reduction. Experimental errors are reviewed for all principal types of data. The data presented are sufficient to estimate (1) the rate of seepage of moisture into the drift; (2) the three-dimensional distribution of hydraulic head in the rock mass to a radial distance of 30 m from the drift; and (3) the three-dimensional distribution of temperature in the rock mass, also to a radial distance of 30 m. These data can in turn be used to estimate the intrinsic permeability of the monitored rock mass. Analysis and interpretation of these results will be presented in subsequent reports.

While theoretical and computational studies have generally focused on specific processes or mechanistic hypotheses, recent methodological and computational advances harken the advent of their principal role in discovery. Here we report the development and application of the ab initio nanoreactor – a highly accelerated, first-principles molecular dynamics simulation of chemical reactions that discovers new molecules and mechanisms without preordained reaction coordinates or elementary steps. Using the nanoreactor we show new pathways for glycine synthesis from primitive compounds proposed to exist on the early Earth, providing new insight into the classic Urey-Miller experiment. These results highlight the emergence of theoretical and computational chemistry as a tool for discovery in addition to its traditional role of interpreting experimental findings. PMID:25411881

    Radiative emission from excited states of atoms and molecules can comprise a significant fraction of the total heat flux experienced by spacecraft during atmospheric entry at hypersonic speeds. For spacecraft with ablating heat shields, some of this radiative flux can be absorbed by molecular constituents in the boundary layer that are formed by the ablation process. Ab initio quantum mechanical calculations are carried out to predict the strengths of these emission and absorption processes. This talk will describe the methods used in these calculations using, as examples, the 4th positive emission bands of CO and the 1g+ 1u+ absorption in C3. The results of these calculations are being used as input to NASA radiation modeling codes like NeqAir, HARA and HyperRad.

    It is suggested that 'freneticism' might be an appropriate name for the type of personality said by Rosenman, Friedman and Jenkins to be at risk from coronary heart disease. In study 1 the measure of this personality type (the JAS) was given a uniform answer format and, as such, was found to give improved reliability. It was administered to a random postal sample of Australians. A short form of 24 items was also produced. In study 2 a similar sample received the 24-item form and scales to measure achievement motivation, dominance and extraversion. 'A' types were found to be very much achievement motivated and dominant. A factor analysis showed these two traits as the main components of the A-B concept with only a third factor of 'freneticism'. This factor was measured in a third study which showed that the factor could be used as a scale in its own right.

    The Hoyle state plays a crucial role in the helium burning of stars heavier than our Sun and in the production of carbon and other elements necessary for life. This excited state of the carbon-12 nucleus was postulated by Hoyle as a necessary ingredient for the fusion of three alpha particles to produce carbon at stellar temperatures. Although the Hoyle state was seen experimentally more than a half century ago nuclear theorists have not yet uncovered the nature of this state from first principles. In this Letter we report the first ab initio calculation of the low-lying states of carbon-12 using supercomputer lattice simulations and a theoretical framework known as effective field theory. In addition to the ground state and excited spin-2 state, we find a resonance at -85(3) MeV with all of the properties of the Hoyle state and in agreement with the experimentally observed energy.

    Processes such as the scattering of alpha particles ((4)He), the triple-alpha reaction, and alpha capture play a major role in stellar nucleosynthesis. In particular, alpha capture on carbon determines the ratio of carbon to oxygen during helium burning, and affects subsequent carbon, neon, oxygen, and silicon burning stages. It also substantially affects models of thermonuclear type Ia supernovae, owing to carbon detonation in accreting carbon-oxygen white-dwarf stars. In these reactions, the accurate calculation of the elastic scattering of alpha particles and alpha-like nuclei--nuclei with even and equal numbers of protons and neutrons--is important for understanding background and resonant scattering contributions. First-principles calculations of processes involving alpha particles and alpha-like nuclei have so far been impractical, owing to the exponential growth of the number of computational operations with the number of particles. Here we describe an ab initio calculation of alpha-alpha scattering that uses lattice Monte Carlo simulations. We use lattice effective field theory to describe the low-energy interactions of protons and neutrons, and apply a technique called the 'adiabatic projection method' to reduce the eight-body system to a two-cluster system. We take advantage of the computational efficiency and the more favourable scaling with system size of auxiliary-field Monte Carlo simulations to compute an ab initio effective Hamiltonian for the two clusters. We find promising agreement between lattice results and experimental phase shifts for s-wave and d-wave scattering. The approximately quadratic scaling of computational operations with particle number suggests that it should be possible to compute alpha scattering and capture on carbon and oxygen in the near future. The methods described here can be applied to ultracold atomic few-body systems as well as to hadronic systems using lattice quantum chromodynamics to describe the interactions of

In 2005, 472 multifamily buildings (10,506 dwellings) were invited (one subject/dwelling) and 7,554 participated (73%). Associations were analyzed by multiple logistic regression, adjusting for gender, age, smoking, country of birth, income and years in the dwelling. In total, 11% had doctor's diagnosed asthma, 22% doctor's diagnosed allergy, 23% pollen allergy and 23% eczema. Doctor's diagnosed asthma was more common in dwellings with humid air (OR = 1.74) and mould odour (OR = 1.79). Doctor's diagnosed allergy was more common in buildings with supply exhaust air ventilation as compared to exhaust air only (OR = 1.45) and was associated with redecoration (OR = 1.48) and mould odour (OR = 2.35). Pollen allergy was less common in buildings using more energy for heating (OR = 0.75) and was associated with humid air (OR = 1.76) and mould odour (OR = 2.36). Eczema was more common in larger buildings (OR 1.07) and less common in buildings using more energy for heating (OR = 0.85) and was associated with water damage (OR = 1.47), humid air (OR = 1.73) and mould odour (OR = 2.01). Doctor's diagnosed allergy was less common in buildings with management accessibility both in the neighbourhood and in larger administrative divisions, as compared to management in the neighbourhood only (OR = 0.49; 95% CI 0.29–0.82).

    Synthetic cannabinoids are a group of psychoactive drugs presently widespread among drug users in Europe. Analytical methods to measure these compounds in urine are in demand as urine is a preferred matrix for drug testing. For most synthetic cannabinoids, the parent compounds are rarely detected in urine. Therefore urinary metabolites are needed as markers of drug intake. AB-FUBINACA was one of the top three synthetic cannabinoids most frequently found in seizures and toxicological drug screening in Sweden (2013-2014). Drug abuse is also reported from several other countries such as the USA and Japan. In this study, 28 authentic case samples were used to identify urinary markers of AB-FUBINACA intake using liquid chromatography quadrupole tandem time of flight mass spectrometry and human liver microsomes. Three metabolites suitable as markers of drug intake were identified and at least two of them were detected in all but one case. In total, 15 urinary metabolites of AB-FUBINACA were reported, including hydrolxylations on the indazole ring and the amino-oxobutane moiety, dealkylations and hydrolysis of the primary amide. No modifications on the fluorobenzyl side-chain were observed. The parent compound was detected in 54% of the case samples. Also, after three hours of incubation with human liver microsomes, 77% of the signal from the parent compound remained. Copyright © 2015 John Wiley & Sons, Ltd.

  3. Organic matter loss from cultivated peat soils in Sweden

    Berglund, Örjan; Berglund, Kerstin

    2015-04-01

    The degradation of drained peat soils in agricultural use is an underestimated source of loss of organic matter. Oxidation (biological degradation) of agricultural peat soils causes a loss of organic matter (OM) of 11 - 22 t ha-1 y-1 causing a CO2 emission of 20 - 40 t ha-1 y-1. Together with the associated N2O emissions from mineralized N this totals in the EU to about 98.5 Mton CO2 eq per year. Peat soils are very prone to climate change and it is expected that at the end of this century these values are doubled. The degradation products pollute surface waters. Wind erosion of peat soils in arable agriculture can cause losses of 3 - 30 t ha-1 y-1 peat also causing air pollution (fine organic particles). Subsidence rates are 1 - 2 cm per year which leads to deteriorating drainage effect and make peat soils below sea or inland water levels prone to flooding. Flooding agricultural peat soils is in many cases not possible without high costs, high GHG emissions and severe water pollution. Moreover sometimes cultural and historic landscapes are lost and meadow birds areas are lost. In areas where the possibility to regulate the water table is limited the mitigation options are either to increase biomass production that can be used as bioenergy to substitute some fossil fuel, try to slow down the break-down of the peat by different amendments that inhibit microbial activity, or permanent flooding. The negative effects of wind erosion can be mitigated by reducing wind speed or different ways to protect the soil by crops or fiber sheets. In a newly started project in Sweden a typical peat soil with and without amendment of foundry sand is cropped with reed canary grass, tall fescue and timothy to investigate the yield and greenhouse gas emissions from the different crops and how the sand effect the trafficability and GHG emissions.

    BACKGROUND. Residential radon is the principal source of exposure to ionizing radiation in most countries. To determine the implications for the risk of lung cancer, we performed a nationwide case-control study in Sweden. METHODS. The study included 586 women and 774 men 35 to 74 years of age with lung cancer that was diagnosed between 1980 and 1984. For comparison, 1380 female and 1467 male controls were studied. Radon was measured in 8992 dwellings occupied by the study subjects at some time since 1947. Information on smoking habits and other risk factors for lung cancer was obtained from questionnaires. RESULTS. Radon levels followed a log-normal distribution, with geometric and arithmetic means of 1.6 and 2.9 pCi per liter (60.5 and 106.5 Bq per cubic meter), respectively. The risk of lung cancer increased in relation to both estimated cumulative and time-weighted exposure to radon. In comparison with time-weighted average radon concentrations up to 1.4 pCi per liter (50 Bq per cubic meter), the relative risk was 1.3 (95 percent confidence interval, 1.1 to 1.6) for average radon concentrations of 3.8 to 10.8 pCi per liter (140 to 400 Bq per cubic meter), and it was 1.8 (95 percent confidence interval, 1.1 to 2.9) at concentrations exceeding 10.8 pCi per liter. The estimates of risk were in the same range as those projected from data in miners. The interaction between radon exposure and smoking with regard to lung cancer exceeded additivity and was closer to a multiplicative effect. CONCLUSIONS. Residential exposure to radon is an important cause of lung cancer in the general population. The risks appear consistent with earlier estimates based on data in miners.

    Birth weight is a significant predictor of breast cancer risk in adult life and mammary gland mass could be an intermediate stage in this long process. We have studied the association of birth size measurements with mammographic density, a marker of mammary gland mass. For a population-based sample of 893 postmenopausal women without previous cancer in Sweden, we retrieved information on birth size from birth records and their most recent mammography. Film mammograms of the medio-lateral oblique view were digitized and the Cumulus software was used for computer-assisted semi-automated thresholding of mammographic density. Results were analyzed using generalized linear models controlling for possible confounders. Mean percent mammographic density increased when comparing the extreme categories of birth weight (from 15.6% to 18.6%) and head circumference (from 15.5% to 20.4%), and the corresponding linear trends were statistically significant (p values 0.02 and 0.007, respectively). The associations were particularly strong when the cutoff for high versus low mammographic density was set at the relatively high value of 50%. Compared to women weighing 3001-3500 grams at birth, women with birth weights >4000g were at almost 3-fold risk of developing high mammographic density (odds ratio: 2.9, 95% confidence interval 1.1 to 7.9). No association with mammographic density was evident with respect to birth length which, however, is known to be less accurately measured. These results indicate that adult breast density, a powerful predictor of breast cancer risk, has intrauterine roots, as reflected in birth size. PMID:19642103

    Poor mental health is common among migrants. This has been explained by migration-related and socio-economic factors. Weak social capital has also been related to poor mental health. Few studies have explored factors that protect mental health of migrants in the post-migration phase. Such knowledge could be useful for health promotion purposes. Therefore, this study aimed to analyse associations between financial difficulties, housing problems and experience of discrimination and poor mental health; and to detect possible effect modification by social capital, among recently settled Iraqi migrants in Sweden. A postal questionnaire in Arabic was sent to recently settled Iraqi citizens. The response rate was 51% (n = 617). Mental health was measured by the GHQ-12 instrument and social capital was defined as social participation and trust in others. Data were analysed by means of logistic regression. Poor mental health was associated with experience of discrimination (OR 2.88, 95% CI 1.73-4.79), housing problems (OR 2.79, 95% CI 1.84-4.22), and financial difficulties (OR 2.14, 95% CI 1.44-3.19), after adjustments. Trust in others seemed to have a protective effect for mental health when exposed to these factors. Social participation had a protective effect when exposed to experience of discrimination. Social determinants and social capital in the host country play important roles in the mental health of migrants. Social capital modifies the effect of risk factors and might be a fruitful way to promote resilience to factors harmful to mental health among migrants, but must be combined with policy efforts to reduce social inequities.

    SummaryIn this study we investigate and characterise the environmental factors that control active speleothem growth in Korallgrottan, northwestern Sweden, in order to get a better understanding of seepage processes in karst areas and to determine whether the fossil speleothems from this site are suitable as palaeoclimatic archives. The drip rates from fast-dripping stalactites (>100 ml/day) vary substantially with the season and the snow regime. Comparisons with measurements of river discharge and simulated ground water recharge show that the drip rate from fast-dripping stalactites can be used as an estimation of the weekly to monthly ground water recharge. Slow-dripping stalactites however, have a steadier drip rate, with almost no seasonal variations. The δ 18O composition of the drip water from both fast- and slow-dripping stalactites show some seasonal variation (±1.2‰), but is fairly stable compared to outside precipitation (±11.1‰). The δ 18O signal from fast-dripping stalactites is biased towards summer conditions, while the signal is dampened at slow-dripping sites and an annual or even longer signal is evident. This holds true even though calcite precipitation may not occur continuously throughout the year. Similarly, the trace elemental composition of drip water is more stable in the slow-dripping stalactites, reflecting mean annual values or longer. Generally the drip water reaches the highest saturation level during the summer and autumn when biological activity in the soil zone is most intense, and the partial pressure of carbon dioxide, which controls limestone dissolution, is high.

    Bacillus thuringiensis strains are well known for the production of insecticidal proteins upon sporulation and these proteins are deposited in parasporal crystalline inclusions. The majority of these insect-specific toxins exhibit three domains in the mature toxin sequence. However, other Cry toxins are structurally and evolutionarily unrelated to this three-domain family and little is known of their three dimensional structures, limiting our understanding of their mechanisms of action and our ability to engineer the proteins to enhance their function. Among the non-three domain Cry toxins, the Cry34Ab1 and Cry35Ab1 proteins from B. thuringiensis strain PS149B1 are required to act together to produce toxicity to the western corn rootworm (WCR) Diabrotica virgifera virgifera Le Conte via a pore forming mechanism of action. Cry34Ab1 is a protein of ∼14 kDa with features of the aegerolysin family (Pfam06355) of proteins that have known membrane disrupting activity, while Cry35Ab1 is a ∼44 kDa member of the toxin_10 family (Pfam05431) that includes other insecticidal proteins such as the binary toxin BinA/BinB. The Cry34Ab1/Cry35Ab1 proteins represent an important seed trait technology having been developed as insect resistance traits in commercialized corn hybrids for control of WCR. The structures of Cry34Ab1 and Cry35Ab1 have been elucidated to 2.15 Å and 1.80 Å resolution, respectively. The solution structures of the toxins were further studied by small angle X-ray scattering and native electrospray ion mobility mass spectrometry. We present here the first published structure from the aegerolysin protein domain family and the structural comparisons of Cry34Ab1 and Cry35Ab1 with other pore forming toxins. PMID:25390338

    Elevated temperatures and pressures are typically thought to have opposing effects on the reaction channels of nitramine decomposition. These high temperatures promote reactions with loose transition structures (positive activation entropies and volumes), such as N-N bond homolysis. Elevated pressures promote reactions with tight transition structures (negative activation entropies and volumes), such as intramolecular and intermolecular H transfer. However, no quantitative data exists regarding the range of temperatures and pressures at which these effects become pronounced. We are pursuing ab initio calculations of the corresponding unimolecular and bimolecular transition structures with the objective of estimating the relevant thermochemical parameters and quantifying the effects of elevated temperature and pressures on the corresponding rate constants. Here, we present density functional theory and complete active space calculations of gas-phase molecular dimers of nitramines as an intermediate step toward modeling transition structures directly in the condensed phase. This work was supported by the Naval Research Laboratory via the American Society for Engineering and Education and by the Office of Naval Research, both directly and through the Naval Research Laboratory.

    We present an ab initio two-component Ehrenfest-based mixed quantum/classical molecular dynamics method to describe the effect of nuclear motion on the electron spin dynamics (and vice versa) in molecular systems. The two-component time-dependent non-collinear density functional theory is used for the propagation of spin-polarized electrons while the nuclei are treated classically. We use a three-time-step algorithm for the numerical integration of the coupled equations of motion, namely, the velocity Verlet for nuclear motion, the nuclear-position-dependent midpoint Fock update, and the modified midpoint and unitary transformation method for electronic propagation. As a test case, the method is applied to the dissociation of H{sub 2} and O{sub 2}. In contrast to conventional Ehrenfest dynamics, this two-component approach provides a first principles description of the dynamics of non-collinear (e.g., spin-frustrated) magnetic materials, as well as the proper description of spin-state crossover, spin-rotation, and spin-flip dynamics by relaxing the constraint on spin configuration. This method also holds potential for applications to spin transport in molecular or even nanoscale magnetic devices.

    2015-01-01

    Glaucoma is a potentially blinding disease that affects millions of people worldwide. The mainstay of treatment is lowering of intraocular pressure (IOP) through the use of medications, laser and/or incisional surgery. The trabecular meshwork (TM) is thought to be the site of significant resistance to aqueous outflow in open angle glaucoma. Theoretically, an incision through TM or TM removal should decrease this resistance and lead to a significant reduction in IOP. This approach, commonly referred to as goniotomy or trabeculotomy, has been validated in the pediatric population and has been associated with long-term IOP control. In adults, however, removal of TM tissue has been historically associated with more limited and short-lived success. More recent evidence, reveals that even adult patients may benefit significantly from removal of diseased TM tissue and can lead to a significant reduction in IOP that is long-lasting and safe. In this review, we discuss current evidence and techniques for ab interno trabeculectomy using various devices in the adult patient. PMID:25624670

  15. ABS_PDv14.0 beta

    2008-07-30

    ABS_PD stands for Adaptive Background Suppression and Peak Detection algorithm. This algorithm uses an iterative process to simultaneously estimate the background and identify peaks in signals where the bakground is slowly varying relative to the peaks to be detected. This is sone on an automated manner. The algorithm can be applied to many physical processes where the desired signal is superimposed on a background. The main advantage of this algorithm is that the background canmore » be variable and doesn't have to be known. All that is required is that a set of basis function,s capa ble of representing the background, needs to be defined. Depending on the signals to be processed, the basis functions can be as simple as low order polynomials. The current algorithm has polynomials built-in and allows for additional basis functions to be defined by the user. An additional advantage is that the algorithm does not use any derivatives in detection of peaks and thus allows for analysis of noisy data. The noise level in the data is automatically taken into account when setting thresholds for peak detection.« less

    Ab initio simulations of large hydrated calcium carbonate clusters are challenging due to the existence of multiple local energy minima. Extensive conformational searches around hydrated calcium carbonate clusters (CaCO3·nH2O for n = 1-18) were performed to find low-energy hydration structures using an efficient combination of Monte Carlo searches, density-functional tight binding (DFTB+) method, and density-functional theory (DFT) at the B3LYP level, or Møller-Plesset perturbation theory at the MP2 level. This multilevel optimization yields several low-energy structures for hydrated calcium carbonate. Structural and energetics analysis of the hydration of these clusters revealed a first hydration shell composed of 12 water molecules. Bond-length and charge densities were also determined for different cluster sizes. The solvation of calcium carbonate in bulk water was investigated by placing the explicitly solvated CaCO3·nH2O clusters in a polarizable continuum model (PCM). The findings of this study provide new insights into the energetics and structure of hydrated calcium carbonate and contribute to the understanding of mechanisms where calcium carbonate formation or dissolution is of relevance.

  18. Phonocatalysis. An ab initio simulation experiment

    2016-06-01

    Using simulations, we postulate and show that heterocatalysis on large-bandgap semiconductors can be controlled by substrate phonons, i.e., phonocatalysis. With ab initio calculations, including molecular dynamic simulations, the chemisorbed dissociation of XeF6 on h-BN surface leads to formation of XeF4 and two surface F/h-BN bonds. The reaction pathway and energies are evaluated, and the sorption and reaction emitted/absorbed phonons are identified through spectral analysis of the surface atomic motion. Due to large bandgap, the atomic vibration (phonon) energy transfer channels dominate and among them is the match between the F/h-BN covalent bond stretching and the optical phonons. We show that the chemisorbed dissociation (the pathway activation ascent) requires absorption of large-energy optical phonons. Then using progressively heavier isotopes of B and N atoms, we show that limiting these high-energy optical phonons inhibits the chemisorbed dissociation, i.e., controllable phonocatalysis.

  19. The impact of a deregulated European electricity market on Volvo in Sweden

    The member countries within the European Union (EU) have agreed to open all national electricity markets for competition, starting January 1, 1999. The electricity market in Sweden is deregulated since January 1, 1996. The deregulation of the electricity markets will gradually shift the electricity price levels in different countries towards an equal price level, which will most likely be close to the levels on the Continental Europe. A deregulated European electricity market may change the competition situation for Swedish industries dramatically. The capacity in electric generation with low operating costs in Sweden has led to very low electricity prices and high usage level compared to other EU countries. The consumption level of electric energy per capita is nearly three times higher in Sweden than the average per capita EU usage. The high level of electricity consumption is typical also of industrial customers in Sweden. Studies of Volvo Car Corporation have shown that the Volvo car plant in Torslanda, Sweden utilizes substantially more electric energy per manufactured car than the Volvo car plant in Gent, Belgium. A method is developed to transform the Torslanda plant from a low energy efficiency state to a higher energy efficiency state by modeling. The method is based on the Life Cycle Cost (LCC) concept and includes optimization models of the two plants with mixed integer linear programming (MILP).

    For a long time, it was considered medical malpractice to neglect the blood group system during transplantation. Because there are far more patients waiting for organs than organs available, a variety of attempts have been made to transplant AB0-incompatible (AB0i) grafts. Improvements in AB0i graft survival rates have been achieved with immunosuppression regimens and plasma treatment procedures. Nevertheless, some grafts are rejected early after AB0i living donor liver transplantation (LDLT) due to antibody mediated rejection or later biliary complications that affect the quality of life. Therefore, the AB0i LDLT is an option only for emergency situations, and it requires careful planning. This review compares the treatment possibilities and their effect on the patients' graft outcome from 2010 to the present. We compared 11 transplant center regimens and their outcomes. The best improvement, next to plasma treatment procedures, has been reached with the prophylactic use of rituximab more than one week before AB0i LDLT. Unfortunately, no standardized treatment protocols are available. Each center treats its patients with its own scheme. Nevertheless, the transplant results are homogeneous. Due to refined treatment strategies, AB0i LDLT is a feasible option today and almost free of severe complications. PMID:27683633

    A new physical method, namely boiling treatment, was developed to aid flotation separation of acrylonitrile-butadiene-styrene (ABS) and polystyrene (PS) plastics. Boiling treatment was shown to be effective in producing a hydrophilic surface on ABS plastic. Fourier Transform Infrared analysis was conducted to investigate the mechanism of boiling treatment of ABS. Surface rearrangement of polymer may be responsible for surface change of boiling treated ABS, and the selective influence of boiling treatment on the floatability of boiling treated plastics may be attributed to the difference in the molecular mobility of polymer chains. The effects of flotation time, frother concentration and particle size on flotation behavior of simple plastic were investigated. Based on flotation behavior of simple plastic, flotation separation of boiling treatment ABS and PS with different particle sizes was achieved efficiently. The purity of ABS and PS was up to 99.78% and 95.80%, respectively; the recovery of ABS and PS was up to 95.81% and 99.82%, respectively. Boiling treatment promotes the industrial application of plastics flotation and facilitates plastic recycling.

    Cry1ab/ac gene was fused by both the cry1ab gene (GenBank Accession No. X54939) and the cry1ac gene (GenBank Accession No. Y09787), which was widely used in genetically modified (GM) rice, cotton, maize and so on. In order to support the safety assessment of GM food or feed products containing Cry1Ab/Ac protein, sufficient quantities of Cry1Ab/Ac protein were produced in Escherichia coli for in vitro evaluation and animal studies. The Cry1Ab/Ac protein does not possess the characteristics associated with food toxins or allergens, i.e., it has no sequence homology with any known allergens or toxins, and no N-glycosylation sites, can be rapidly degraded in gastric and intestinal fluids, and is devoid of adverse effects in mice by gavage at a high dose level of 5g (Cry1Ab/Ac protein)/kg body weight. In conclusion, there is a reasonable certainty of no harm resulting from the inclusion of the Cry1Ab/Ac protein in human food or animal feed.

    Pathogenic strains of Escherichia coli produce a number of toxins that belong to the AB5 toxin family, which comprise a catalytic A-subunit that induces cellular dysfunction and a B-pentamer that recognizes host glycans. Although the molecular actions of many of the individual subunits of AB5 toxins are well understood, how they self-associate and the effect of this association on cytotoxicity are poorly understood. Here we have solved the structure of the holo-SubAB toxin that, in contrast to other AB5 toxins whose molecular targets are located in the cytosol, cleaves the endoplasmic reticulum chaperone BiP. SubA interacts with SubB in a similar manner to other AB5 toxins via the A2 helix and a conserved disulfide bond that joins the A1 domain with the A2 helix. The structure revealed that the active site of SubA is not occluded by the B-pentamer, and the B-pentamer does not enhance or inhibit the activity of SubA. Structure-based sequence comparisons with other AB5 toxin family members, combined with extensive mutagenesis studies on SubB, show how the hydrophobic patch on top of the B-pentamer plays a dominant role in binding the A-subunit. The structure of SubAB and the accompanying functional characterization of various mutants of SubAB provide a framework for understanding the important role of the B-pentamer in the assembly and the intracellular trafficking of this AB5 toxin.

    I propose a simple and manageable method that allows for deriving coupling constants of model energy density functionals (EDFs) directly from ab initio calculations performed for finite fermion systems. A proof-of-principle application allows for linking properties of finite nuclei, determined by using the nuclear nonlocal Gogny functional, to the coupling constants of the quasilocal Skyrme functional. The method does not rely on properties of infinite fermion systems but on the ab initio calculations in finite systems. It also allows for quantifying merits of different model EDFs in describing the ab initio results.

    A hierarchical parallelization has been implemented in a new unified code PIMD-SMASH for ab initio simulation where the replicas and the Born-Oppenheimer forces are parallelized. It is demonstrated that ab initio path integral molecular dynamics simulations can be carried out very efficiently for systems up to a few tens of water molecules. The code was then used to study a Diels-Alder reaction of cyclopentadiene and butenone by ab initio string method. A reduction in the reaction energy barrier is found in the presence of hydrogen-bonded water, in accordance with experiment.

    Candidatus Neoehrlichia mikurensis (CNM; family Anaplasmataceae) was recently recognized as a potential tick-borne human pathogen. The presence of CNM in mammals, in host-seeking Ixodes ticks and in ticks attached to mammals and birds has been reported recently. We investigated the presence of CNM in ornithophagous ticks from migrating birds. A total of 1,150 ticks (582 nymphs, 548 larvae, 18 undetermined ticks and two adult females) collected from 5,365 birds captured in south-eastern Sweden was screened for CNM by molecular methods. The birds represented 65 different species, of which 35 species were infested with one or more ticks. Based on a combination of morphological and molecular species identification, the majority of the ticks were identified as Ixodes ricinus. Samples were initially screened by real-time PCR targeting the CNM 16S rRNA gene, and confirmed by a second real-time PCR targeting the groEL gene. For positive samples, a 1260 base pair fragment of the 16S rRNA gene was sequenced. Based upon bacterial gene sequence identification, 2.1% (24/1150) of the analysed samples were CNM-positive. Twenty-two out of 24 CNM-positive ticks were molecularly identified as I. ricinus nymphs, and the remaining two were identified as I. ricinus based on morphology. The overall CNM prevalence in I. ricinus nymphs was 4.2%. None of the 548 tested larvae was positive. CNM-positive ticks were collected from 10 different bird species. The highest CNM-prevalences were recorded in nymphs collected from common redpoll (Carduelis flammea, 3/7), thrush nightingale (Luscinia luscinia, 2/29) and dunnock (Prunella modularis, 1/17). The 16S rRNA sequences obtained in this study were all identical to each other and to three previously reported European strains, two of which were obtained from humans. It is concluded that ornithophagous ticks may be infected with CNM and that birds most likely can disperse CNM-infected ticks over large geographical areas. PMID:26207834

    The focus of this study is to examine to what extent and in what ways science teachers practice assessment during classroom interactions in everyday activities in an upper-secondary school in Sweden. We are science teachers working now with a larger research project on assessment in science education that seeks to examine teachers' assessment practices in the upper-secondary school. Framing questions include: are teachers performing an integrated assessment of students' skills as the national curriculum mandates? If so, what do the instructional discourses look like in those situations and what are students' experiences regarding their agency on learning and assessment? We emphasize the social, cultural and historic character of assessment and sustain a situated character of learning instead of the notion that learning is "stored inside the head". Teacher led lessons in three science classrooms were video-recorded and analyzed by combining ethnographic and discourse methods of analysis. Both methods are appropriate to the theoretical foundation of our approach on learning and can give some answers to questions about how individuals interact socially, how their experience is passed on to next generations through language and how language use may reveal cultural changes in the studied context. Making the study of action in a classroom the focal point of sociocultural analysis supports the examination of assessment processes and identification of the social roles in which teachers and students are immersed. Such an approach requires observations of how teachers act in authentic teaching situations when they interact with their students in classroom making possible to observe negotiation processes, agencies when both teachers and students are involved in every-day activities. Our study showed that teachers mostly ignored students' questions and that students solved their own problems by helping each other. Teachers did not provide opportunities for students to discuss

  11. Winter performance of an urban stormwater pond in southern Sweden

    Evidence from cold regions in North America has shown that the performance of stormwater ponds differs between winter and summer. The pond hydraulics change seasonally, and winters have lowered removal efficiency due to a combination of an ice cover, cold water and de-icing salts. This study examines the function of the Bäckaslov stormwater pond under the more mild conditions of southern Sweden, where there are several snow and melt cycles per year.Event sampling in the summer of 1997 showed good removal efficiencies for nutrients, total suspended solids (TSS) and a selection of metals (Cd, Cu, Pb, Zn), but winter grab-tests taken in 1995-96 and 1997-98 suggest that the pond acts as a pollutant source under cold conditions. To better assess winter and spring pond performance, water at the inflow and outflow was sampled from January to April 2003. The low intensity of runoff delivery and slow inflow velocities meant that time- rather than flow-weighted sampling was used. Five consecutive events were sampled and analysed for TSS, chloride and the metals As, Cd, Cr, Cu, Hg, Ni, Pb and Zn. YSI probes were in place at both the inlet (pH, temperature) and outlet (pH, temperature, conductivity, dissolved oxygen) to determine the timing of pollution flows. In addition, profiles of the same quality indicators allowed snapshots of pond processes.De-icing salt has a major effect on pond hydraulics. Strong stratification occurred after each snowmelt-generated flow event and up to 80% of chloride could be retained by the pond. However, continuous conductivity measurements show that chloride is flushed between events. Ice changes retention times and causes oxygen depletion, but bed scour was not observed. Pond performance decreased during the winter and spring, albeit not as badly as the grab tests suggest. A seasonal comparison of the removal efficiencies showed that removal of Cd (75%) and Cu (49%) was about the same for summer and winter-spring, but removal of Pb, Zn and TSS

    Local seismic system consisting of 18 sensors 4.5 Hz was installed in Zinkgruvan Mine (Sweden) in 2015 at depth ˜1140 m. The system is concentrated in a small area of 40 x 50 m and is able to record very small seismic events (magnitude -4 or lower) induced by the mining activity. This study is related to two larger seismic events with moment magnitudes 0.6 and 1.2 that occurred in two consecutive days and their aftershock series on July 1 and 2, 2015. The first seismic events occurred seconds after a blast and the second one during blasting. The latter one caused a rockburst and extensive damage in the mine. More than 3000 seismic events were recorded at distances up to 100 m from the local seismic system during these two days. Manual data processing was done only for the events recorded by more than 15 sensors following the larger events and 3 hours before them. In total approximately 240 events have been analyzed. Seismic event locations and other source parameters were obtained by IMS Trace software. The aftershock areas of the two seismic events formed two separate aftershock areas, The first series (Mw -3 to -1) lasted about one hour but the second one (Mw -3 to 0) was more complicated with two larger aftershocks (Mw 0.3 and 0.7) with their own aftershock series within 90 minutes. Based on the Es/Ep energy ratio the main events were classified as shear seismic events (Es/Ep ˜10). The other events were approximately equally divided between shear and not-shear (tensile) events. No apparent correlation was found between the type of the events and the magnitude. The apparent stress of both series varied within four orders (from 6.7*103 to 2.4*107 Pa) with a weak trend of increase with the magnitude. The configuration and source parameters of the aftershock series were related to the observed damage due to the rockburst on July 2, 2015. The results were used to obtain a possible mechanism of the main events.

    Recent studies have shown that climate change in northern high latitudes plays a significant role in enhancing the mobilization of previously sequestered mercury (Hg) in peatlands to the atmosphere and hydrosphere. The magnitude and mechanics of Hg mobilization, however, remain poorly constrained. To investigate the coupling of different export pathways and the major fate and transport of Hg in a subarctic ecosystem, we measured atmospheric Hg fluxes across a permafrost thaw gradient and compared these fluxes with exchangeable Hg from peat cores collected in July 2012 and July 2013 at the Stordalen Mire, Abisko, Sweden (68°21'N). Mercury flux measurements were estimated using a Tekran 2537 ambient air mercury analyzer integrated into a dynamic chamber system. The nine chamber array is divided into three sites, three chambers per site: (1) palsa site: dwarf-shrub dominated hummocks overlying permafrost, (2) Sphagnum : semi-wet hollows with 100% sphagnum cover with minor Eriophorum vaginatum, and (3) Eriophorum: wet hollows dominated by Carex rostrata and Eriophorum angustifolium. Continuous ambient air Hg measurements were made for multiple days at each site prior to flux chamber measurements. All three sites show a diel pattern characterized by Hg deposition during lows of photosynthetically active radiation (PAR) and ground temperature and a release of Hg during the peak PAR and ground temperature periods (13:00-15:00h). The palsa site yielded the highest Hg flux accompanied with the least amount of Hg deposition in the evening. The Eriophorum releases the least amount of Hg and is associated with the highest Hg deposition. The Sphagnum shows the most variability of the three sites, at times releasing as much as the palsa site but absorbing more than the Eriophorum in one instance. Consideration of the Hg flux measurements together with exchangeable Hg concentrations of the peat suggests that the palsa has the highest amount of stored Hg and given the aerobic

    This paper analyzes how sustained yield (SY) forestry is defined and implemented in Sweden and Russia, two countries with different forest-industrial regimes. We first compare definitions of SY forestry in national legislation and policies. Then we study forest management planning in two large forest management units with respect to: delivered forest products and values, how the harvest level of timber is defined, where the harvest takes place, and what treatments are used to sustain desired forest products and values. In Sweden SY forestry is maximum yield based on high-input forest management, and in Russia it is forestry based on natural regeneration with minimum investments in silviculture. We conclude that how SY forestry contributes to SFM depends on the context. Finally, we discuss the consequences of SY forestry as performed in Sweden and Russia related to its ability to support diverse forest functions, as envisioned in sustainable forest management policy.

    This paper presents Salmonella data from animals, feedstuffs and feed mills in Sweden between 1993 and 1997. During that period, 555 isolates were recorded from animals, representing 87 serotypes. Of those, 30 serotypes were found in animals in Sweden for the first time. The majority of all isolates from animals were S. Typhimurium (n = 91), followed by S. Dublin (n = 82). There were 115 isolates from cattle, 21 from broilers, 56 from layers and 18 from swine. The majority of these isolates were from outbreaks, although some were isolated at the surveillance at slaughterhouses. The number of isolates from the feed industry was similar to that of the previous 5-year period. Most of those findings were from dust and scrapings from feed mills, in accordance with the HACCP programme in the feed control programme. It can be concluded that the occurrence of Salmonella in animals and in the feed production in Sweden remained favourable during 1993–97. PMID:15074631

    The 1920s saw a significant exchange between eugenicists in Sweden and the young Soviet state. Sweden did not take part in World War I, and during the years following immediately upon the Versailles peace treaty, Swedish scholars came to serve as an intermediary link between, on the one hand, Soviet Russia and Weimar Germany, and, on the other hand, Western powers. Swedish eugenicists organized conferences, lecture tours, visits, scholarly exchanges, and transfers and translation of eugenic research. Herman Lundborg, the director of the world's first State Institute of Racial Biology, was an old-fashioned, deeply conservative, and anti-communist "scientific" racist, who somewhat paradoxically came to serve as something of a Western liaison for Soviet eugenicists. Whereas the contacts were disrupted in 1930, Swedish eugenicists had a lasting impact on Soviet physical anthropologists, who cited their works well into the 1970s, long after they had been discredited in Sweden.

    Ab initio results on the band structure, density of states, and Fermi surface (FS) properties of LaRu{sub 4}X{sub 12} (X = P, As, Sb) are presented at ambient pressure as well as under compression. The analysis of density of states reveals the major contribution at the Fermi level to be mainly from the Ru-d and X-p states. We have a complicated Fermi surface with both electron and hole characters for all the three compounds which is derived mainly from the Ru-d and X-p states. There is also a simpler FS with hole character derived from the P-p{sub z} orbital for LaRu{sub 4}P{sub 12} and Ru-d{sub z{sup 2}} orbital in the case of As and Sb containing compounds. More interestingly, Fermi surface nesting feature is observed only in the case of the LaRu{sub 4}P{sub 12}. Under compression, we observe the topology of the complicated FS sheet of LaRu{sub 4}As{sub 12} to change around V/V{sub 0} = 0.85, leading to a behaviour similar to that of a multiband superconductor, and in addition, we have two more hole pockets centered around Γ at V/V{sub 0} = 0.8 for the same compound. Apart from this, we find the hole pocket to vanish at V/V{sub 0} = 0.8 in the case of LaRu{sub 4}Sb{sub 12} and the opening of the complicated FS sheet gets reduced. The de Haas van Alphen calculation shows the number of extremal orbits in the complicated sheet to change in As and Sb containing compounds under compression, where we also observe the FS topology to change.

    We report on the determination of a high quality ab initiu potential energy surface (PES) and dipole moment function for water. This PES is empirically adjusted to improve the agreement between the computed line positions and those from the HITRAN 92 data base with J less than 6 for H2O. The changes in the PES are small, nonetheless including an estimate of core (oxygen 1s) electron correlation greatly improves the agreement with experiment. Using this adjusted PES, we can match 30,092 of the 30,117 transitions in the HITRAN 96 data base for H2O with theoretical lines. The 10,25,50,75, and 90 percentiles of the difference between the calculated and tabulated line positions are -0.11, -0.04, -0.01, 0.02, and 0.07 l/cm. Non-adiabatic effects are not explicitly included. About 3% of the tabulated line positions appear to be incorrect. Similar agreement using this adjusted PES is obtained for the oxygen 17 and oxygen 18 isotopes. For HDO, the agreement is not as good, with root-mean-square error of 0.25 l/cm for lines with J less than 6. This error is reduced to 0.02 l/cm by including a small asymmetric correction to the PES, which is parameterized by simultaneously fitting to HDO md D2O data. Scaling this correction by mass factors yields good results for T2O and HTO. The intensities summed over vibrational bands are usually in good agreement between the calculations and the tabulated results, but individual lines strengths can differ greatly. A high temperature list consisting of 307,721,352 lines is generated for H2O using our PES and dipole moment function.

    The distributional area of the tick Ixodes ricinus (L.), the primary European vector to humans of Lyme borreliosis spirochaetes (Borrelia burgdorferi sensu lato) and tick-borne encephalitis virus, appears to be increasing in Sweden. It is therefore important to determine which environmental factors are most useful to assess risk of human exposure to this tick and its associated pathogens. The geographical distribution of I. ricinus in Sweden was analysed with respect to vegetation zones and climate. The northern limit of I. ricinus and B. burgdorferi s.l. in Sweden corresponds roughly to the northern limit of the southern boreal vegetation zone, and is characterized climatically by snow cover for a mean duration of 150 days and a vegetation period averaging 170 days. The zoogeographical distribution of I. ricinus in Sweden can be classified as southerly-central, with the centre of the distribution south of the Limes Norrlandicus. Ixodes ricinus nymphs from 13 localities in different parts of Sweden were examined for the presence of B. burgdorferi s.l. and found to be infected with Borrelia afzelii and Borrelia garinii. Tick sampling localities were characterized on the basis of the density of Borrelia-infected I. ricinus nymphs, presence of specific mammals, dominant vegetation and climate. Densities of I. ricinus nymphs and Borrelia-infected nymphs were significantly correlated, and nymphal density can thus serve as a general indicator of risk for exposure to Lyme borreliosis spirochaetes. Analysis of data from this and other studies suggests that high densities of Borrelia-infected nymphs typically occur in coastal, broadleaf vegetation and in mixed deciduous/spruce vegetation in southern Sweden. Ixodes ricinus populations consistently infected with B. burgdorferi s.l. can occur in: (a) biotopes with shrews, rodents, hares and birds; (b) biotopes with shrews, rodents, hares, deer and birds, and (c) island locations where the varying hare (Lepus timidus) is the

    In 2010, cancer deaths accounted for more than 15% of all deaths worldwide, and this fraction is estimated to rise in the coming years. Increased cancer mortality has been observed in immigrant populations, but a comprehensive analysis by country of birth has not been conducted. We followed all individuals living in Sweden between 1961 and 2009 (7,109,327 men and 6,958,714 women), and calculated crude cancer mortality rates and age-standardized rates (ASRs) using the world population for standardization. We observed a downward trend in all-site ASRs over the past two decades in men regardless of country of birth but no such trend was found in women. All-site cancer mortality increased with decreasing levels of education regardless of sex and country of birth (p for trend <0.001). We also compared cancer mortality rates among foreign-born (13.9%) and Sweden-born (86.1%) individuals and determined the effect of education level and sex estimated by mortality rate ratios (MRRs) using multivariable Poisson regression. All-site cancer mortality was slightly higher among foreign-born than Sweden-born men (MRR = 1.05, 95% confidence interval 1.04-1.07), but similar mortality risks was found among foreign-born and Sweden-born women. Men born in Angola, Laos, and Cambodia had the highest cancer mortality risk. Women born in all countries except Iceland, Denmark, and Mexico had a similar or smaller risk than women born in Sweden. Cancer-specific mortality analysis showed an increased risk for cervical and lung cancer in both sexes but a decreased risk for colon, breast, and prostate cancer mortality among foreign-born compared with Sweden-born individuals. Further studies are required to fully understand the causes of the observed inequalities in mortality across levels of education and countries of birth.

    The tensile deformation mechanisms of acrylonitrile - butadiene - styrene (ABS) / polymethyl methacrylate (PMMA) blends toughened by ethylene methacrylate (EMA) copolymer was investigated by analysing the fracture morphology. ABS/PMMA was blended with EMA copolymer by melt mixing technique using co-rotating twin extruder. Tensile tests show that the elongation at break of ABS/PMMA blends can be efficiently improved with the increase in EMA content. Fracture morphology of ABS/PMMA/EMA blends reveals that the material yield induced by hollowing-out of EMA particles and its propagation into yield zone is the main toughening mechanism. Moreover, the appearance that EMA particles in the central area are given priority to hollowing-out may be related to the skin-core structure of the injection moulded parts caused by the different cooling rate between surface and inside in the process of injection moulding.

    2011-04-11

    A long-standing goal of nuclear theory is to determine the properties of atomic nuclei based on the fundamental interactions among the protons and neutrons (i.e., nucleons). By adopting nucleon-nucleon (NN), three-nucleon (NNN) and higher-nucleon interactions determined from either meson-exchange theory or QCD, with couplings fixed by few-body systems, we preserve the predictive power of nuclear theory. This foundation enables tests of nature's fundamental symmetries and offers new vistas for the full range of complex nuclear phenomena. Basic questions that drive our quest for a microscopic predictive theory of nuclear phenomena include: (1) What controls nuclear saturation; (2) How the nuclear shell model emerges from the underlying theory; (3) What are the properties of nuclei with extreme neutron/proton ratios; (4) Can we predict useful cross sections that cannot be measured; (5) Can nuclei provide precision tests of the fundamental laws of nature; and (6) Under what conditions do we need QCD to describe nuclear structure, among others. Along with other ab initio nuclear theory groups, we have pursued these questions with meson-theoretical NN interactions, such as CD-Bonn and Argonne V18, that were tuned to provide high-quality descriptions of the NN scattering phase shifts and deuteron properties. We then add meson-theoretic NNN interactions such as the Tucson-Melbourne or Urbana IX interactions. More recently, we have adopted realistic NN and NNN interactions with ties to QCD. Chiral perturbation theory within effective field theory ({chi}EFT) provides us with a promising bridge between QCD and hadronic systems. In this approach one works consistently with systems of increasing nucleon number and makes use of the explicit and spontaneous breaking of chiral symmetry to expand the strong interaction in terms of a dimensionless constant, the ratio of a generic small momentum divided by the chiral symmetry breaking scale taken to be about 1 GeV/c. The resulting NN

    Monolayer α-graphyne is a new two-dimensional carbon allotrope with many special features. In this work the electronic properties of AA- and AB-stacked bilayers of this material and then the optical properties are studied, using first principle plane wave method. The electronic spectrum has two Dirac cones for AA stacked bilayer α-graphyne. For AB-stacked bilayer, the interlayer interaction changes the linear bands into parabolic bands. The optical spectra of the most stable AB-stacked bilayer closely resemble to that of the monolayer, except for small shifts of peak positions and increasing of their intensity. For AB-stacked bilayer, a pronounced peak has been found at low energies under the perpendicular polarization. This peak can be clearly ascribed to the transitions at the Dirac point as a result of the small degeneracy lift in the band structure.

    A C-130J-30 Super Hercules plane crashed into the west-facing wall of the Kebnekaise mountain (2103 m), Arctic Sweden, on March 15th 2012. When starting from Evenes, Narvik, Norway, the aircraft had 14100 l fuel, 50 l hydraulic oil and 170 l motor oil onboard. Best estimates are that at least 12 000 l of fuel was sprayed over the mountain most of which was buried together with the wreck in a huge snow avalanche that was triggered by the impact in a NW facing cirque on Rabots glacier between ca 1600 and 2000 m. Fuel decontamination was not possible because of the extreme impact site conditions. The Hercules airplane was fueled with JET A-1 which is a hydrocarbon product in the Kerosene/Jet Fuel category consisting of sweetened kerosene and hydrotreated light distillates. The major components of all 'kerosene's' are branched- and straight-chain paraffins and naphthenes (cycloparaffins or cycloalkanes), which normally account for 70% by volume. Aromatic hydrocarbons, such as alkyl benzenes (single ring) and alkylnaphthalenes (double ring) do not exceed 25 % by volume of kerosene. The fuel also contains polycyclic aromatic hydrocarbons (PAH), but in very small volumes compared to the major components. The physical and chemical properties of each component (or block) of the hydrocarbon mixture influence its migration rate and fate. Some components of the fuel will volatilize, some are soluble in water but the vast majority are non-soluble. Although the solubility of these so called Light Nonaqueous Phase Liquids (LNAPL) in water is small they are highly toxic. We need to consider transport of the soluble components of the LNAPL in the melt-water, and transport of the non-soluble components with the melt-water system. Transport and storage can occur through and in snow (or firn), crevasses, and cavities on, in or under the glacier. Storage in, and contamination of, basal sediments, located below the glacier, or pro-glacial sediments, in front of the glacier are also

    The Lockne impact crater south of Östersund formed in the early Middle Cambrian with a diameter of 7 km. It is identified by its rim wall of crushed Precambrian basement granite, by fragments of impact melt, and by grains of shocked quartz. The exceptional preservation, in particular of the rim wall, is due to a complicated geological history, the first stage of which consisted of burial by marine sediments. This stage lasted until the Middle Ordovician, or over 50 million years. An early Caradoc lowering of the sea-level may have induced debris flows that stripped the rim wall of much of its sedimentary cover. Because normal marine sedimentation recommenced soon after this event, the structure was not seriously damaged, as it was buried again. The Caledonian orogeny emplaced an overthrust nappe as ultimate protection, which was removed by a recent erosion episode from all but the center of the structure. Structures formed by the impact of extraterrestrial bodies are very rare throughout much of Europe, because such structures are neither well preserved nor displayed in young mountain belts or sedimentary basins. However, northern Europe has several ascertained structures of this kind ( Svensson & Wickman, 1965; Svensson, 1968; Bruun & Dahlman, 1982; Kala et al., 1984; Flodén et al., 1986; Wickman, 1988). Unfortunately, the hitherto known structures are either poorly preserved or hidden by younger deposits. We are reporting the discovery of a well-preserved exposed and accessible impact structure that has escaped the notice of geologists although important features of it have been described and puzzled over by generations of researchers ( Wiman, 1900; Hadding, 1927; Thorslund, 1940; Lindström et al., 1983). The structure is located in the Lockne area to the south of Östersund in central Sweden. It has a diameter of 7 km and its center is near Tramsta on the northwest shore of Lake Locknesjön (Fig. 1). Its middle is covered by folded Lower to Middle Ordovician

  15. Can we disentangle life course processes of accumulation, critical period and social mobility? An analysis of disadvantaged socio-economic positions and myocardial infarction in the Stockholm Heart Epidemiology Program.

    The accumulation hypothesis would propose that the longer the duration of exposure to disadvantaged socio-economic position, the greater the risk of myocardial infarction. However there may be a danger of confounding between accumulation and possibly more complex combinations of critical periods of exposure and social mobility. The objective of this paper is to investigate the possibility of distinguishing between these alternatives. We used a population based case-control study (Stockholm Heart Epidemiology Programme) of all incident first events of myocardial infarction among men and women, living in the Stockholm region 1992-94. The analyses were restricted to men 53-70 years, 511 cases and 716 controls. From a full occupational history each subject was categorized as manual worker or non-manual at three stages of the life course, childhood (from parent's occupation), at the ages 25-29 and 51-55, resulting in 8 possible socio-economic trajectories. We found a graded response to the accumulation of disadvantaged socio-economic positions over the life course. However, we also found evidence for effects of critical periods and of social mobility. A conceptual analysis showed that there are, for theoretical reasons, only a limited number of trajectories available, too small to form distinct empirical categories of each hypothesis. The empirical task of disentangling the life course hypotheses of critical period, social mobility and accumulation is therefore comparable to the problem of separating age, period, and cohort effects. Accordingly, the interpretation must depend on prior knowledge of more specific causal mechanisms.

    Verhoef, T I; Redekop, W K; Langenskiold, S; Kamali, F; Wadelius, M; Burnside, G; Maitland-van der Zee, A-H; Hughes, D A; Pirmohamed, M

    2016-10-01

    We aimed to assess the cost-effectiveness of pharmacogenetic-guided dosing of warfarin in patients with atrial fibrillation (AF) in the United Kingdom and Sweden. Data from EU-PACT, a randomized controlled trial in newly diagnosed AF patients, were used to model the incremental costs per quality-adjusted life-year (QALY) gained by pharmacogenetic-guided warfarin dosing versus standard treatment over a lifetime horizon. Incremental lifetime costs were £26 and 382 Swedish kronor (SEK) and incremental QALYs were 0.0039 and 0.0015 in the United Kingdom and Sweden, respectively. The corresponding incremental cost-effectiveness ratios (ICERs) were £6 702 and 253 848 SEK per QALY gained. The ICER was below the willingness-to-pay threshold of £20 000 per QALY gained in 93% of the simulations in the United Kingdom and below 500 000 SEK in 67% of the simulations in Sweden. Our data suggest that pharmacogenetic-guided dosing of warfarin is a cost-effective strategy to improve outcomes of patients with AF treated with warfarin in the United Kingdom and in Sweden.
