    The three-yearly Liquid Matter Conference is organized by the Liquids Section of the Condensed Matter Division of the European Physical Society. This series of meetings began in Lyon in 1990. The previous meeting was held in 2005 in Utrecht. The original aim of the Liquid Matter Conference was to bring together scientists working on the liquid state of matter. A closer analysis of the program booklets over the past 18 years reveals that new and highly active research fields that are closely related to liquid matter have been successfully integrated in the scope of the conference, notably the rapidly developing fields of soft matter and biophysics. Concomitantly, a broadening of the spectrum from the classical liquid state to a wide spectrum of phases and systems could be observed. Therefore, the rapidly growing field covered by this conference series at present includes physics, chemistry, biology, and chemical engineering as well as various applied research areas. Liquid state physics is at the interface of many research fields. As a consequence, many of the attendants come from adjacent fields and encounter at the Liquid Matter Conference a community where they can meet experts from other research areas. This aspect of the Liquid Matter Conference makes it an exciting meeting as it not only offers the participants an up-to-date picture of the status of research into the liquid state of matter, but it also allows them to establish new (and often unexpected) transdisciplinary contacts for joint scientific endeavours. This applies in particular to the area of soft condensed matter such as colloidal suspensions, polymeric systems and biological materials. The Lund meeting, organized in collaboration with Lund University, had 574 registered participants from five continents. During the conference, and following the tradition established at the Utrecht meeting, the second Liquid Matter Prize of the European Physical Society was awarded to Professor Henk Lekkerkerker

    Neutron scattering is used as a tool to study problems in disciplines that include chemistry, materials science, biology and condensed matter physics as well as problems from neighbouring disciplines such as geology, environmental sciences and archaeology. Equipment for these studies is found at laboratories with research reactors or spallation neutron sources and there are many recent or current developments with new instruments and even entirely new facilities such as the Spallation Neutron Source at Oak Ridge, USA, the OPAL reactor at Lucas Heights, Australia and the second target station at the ISIS facility in the UK. Design and optimization of the instruments at these facilities involves work with many research laboratories and groups in universities. Every four years the European Conference on Neutron Scattering (ECNS) brings together both the specialists in neutron instrumentation and the community of users (in intervening years there are International and American conferences). In June 2007 about 700 delegates came to the 4th ECNS that was held in Lund, Sweden. There were more than 600 presentations as talks and posters. The opportunity to publish papers in Measurement Science and Technology that relate to neutron scattering instrumentation and method development was offered to the participants, and the papers that follow describe some of the recent activity in this field. Accounts of work on condensed matter science and the applications of neutron scattering appear separately in Journal of Physics: Condensed Matter. There are, of course, many features of neutron instrumentation that are specific to this particular field of measurement. However, there are also many elements of apparatus and experiment design that can usefully be shared with a broader community. It is hoped that this issue with papers from ECNS will find a broad community of interest. Apart from descriptions of overall design of diffractometers and spectrometers there are accounts of new

    The Mendelian Society in Lund was founded in 1910. The initiative came from two young biologists supported by a wide circle of interested plant breeders and academics. Already from the start the society was dominated by the towering personality Herman Nilsson-Ehle. After two active years, the Society went into temporal hibernation until it resumed its activities in spring 1916, when Nilsson-Ehle was on his way to become Sweden's first professor of genetics. One of the aims of the Society was to launch a scientific journal for local scientists directed at an international audience. After a successful fundraising campaign, Hereditas was started in 1920. One of the original instigators of the Mendelian Society, Robert Larsson, became its first editor, and he remained in this position for more than 30 years. Both he and Nilsson-Ehle were fascinating personalities, deeply rooted in their time's scientific and ideological debates. PMID:25491746

    Researchers in Sweden are "confident" they will host Europe's next-generation neutron facility that, once built, will be the most powerful source of neutrons in the world. The €1.48bn European Spallation Source (ESS) will cater for thousands of researchers every year in fields from condensed-matter physics to biology. A decision on where the ESS will be built - Lund in Sweden, Bilbao in Spain or Debrecen in Hungary - was due to be announced as Physics World went to press, with Sweden the front-runner.

    ter Schure, Arnout F. H.; Larsson, Per

    The presence of polybrominated diphenyl ether (PBDE) flame retardants in total deposition (wet+dry) was assessed with the simultaneous use of three bulk samplers during a 2 week period. The particle associated and the 'dissolved' phase were separated during sampling. Volume weighted mean (VWM) concentrations of ∑PBDE (9 congeners) in rain were 209 pg l -1. Total deposition rates were 2±1 ng ∑PBDE m -2 day -1. The total PBDE deposition was dominated by decaBDE(209) and thereafter 2,2'4,4'-tetraBDE(47) and 2,2'4,4',5-pentaBDE(99). Concentrations of particle associated and 'dissolved' PBDEs in total deposition were used to calculate filter/adsorbent ratios ( F/ A). We found that 65±18% of the total PBDEs were particle associated. Low F/ A ratios for higher brominated congeners (Br>5) were observed. This is contradictory with predictions based on the PBDEs' physico-chemical properties and was attributed to sampling artefacts, such as particle size distribution, and/or non-equilibrium processes. There was a negative relationship between the particulate ∑PBDE concentration and rain volume suggesting a dilution effect and the importance of particle scavenging for wet deposition of PBDEs.

    2004-01-01

    The Swedish physician and Professor of Anatomy Ivar Broman (1868-1946) came from a poor countryside family in the province of Skåne, southern Sweden. As he was intelligent and talented he received help from local people to get him an education at the nearby University of Lund. He stayed both there and at the University in Uppsala, but also in Kiel, Germany, during his early years. Soon Ivar Broman showed his dedication for embryology and comparative anatomy, publishing several books and papers. Later on he also wrote several contributions for daily newspapers, telling about new scientific discoveries and public health related issues. At one occassion Ivar Broman went to Africa for collecting embryos of different mammals. In the political world he showed strong emotional ties to Germany where he had several friends and contacts in medicine. This led Ivar Broman to sign, among 400 other people, a pamphlet calling for establishing a Swedish-German friendship organisation in 1938. He was not a party member of any Nazi party, but was, similar to other of his contemporary friends and scientists, an admirer of German science and culture. In some of his writings Broman was very modern in try to popularize science and new discoveries, but also devoted to aspects of purifying the population and using racial biological arguments. The lesson from Ivar Broman is that a devoted and skilled scientist, with many modern views, could also hold some authoritarian and politically darker views. This could be an example of a "Faustian" dilemma in science during a period of political tensions and distant thunders of war. PMID:16025611

    This study aims to analyse mental symptoms, psychotropic drug use and alcohol consumption, in immigrant women born in Finland, the other Nordic countries, Eastern Europe, Western Europe and countries outside Europe, compared with Swedish-born women, and furthermore, to study if age at immigration may have an influence. All women (n=10,766) aged 50-59 years and living in the Lund area of southern Sweden received a postal invitation to a health survey named the Women's Health in Lund Area; 64.2% (n=6917) participated. The participants answered a questionnaire including prevalence of mental symptoms during the past 3 months, regular use of psychotropic drugs, alcohol consumption during an average week, country of birth and age at immigration. Severe mental symptoms were more common among most immigrant groups compared with native Swedes, but the association to country of birth was not significant after adjustment for possible confounders. Regular use of hypnotics was more common among Nordic immigrants only (odds ration, OR = 4.4). East European and non-European immigrants less often were alcohol consumers (OR = 1.6 and OR = 3.8). Heavy drinking was more common among non-Nordic immigrants who immigrated at a younger age than at an older age. Furthermore, it was found that although East European and non-European immigrants had a higher educational level, they were less often gainfully employed compared with native Swedes. In middle-aged women, country of birth as well as age at immigration are important factors to consider in relation to alcohol consumption, but these factors may be of less importance considering mental health.

    Unusual monotonous intermediate ignimbrites consist of phenocryst-rich dacite that occurs as very large volume (>1000 km 3) deposits that lack systematic compositional zonation, comagmatic rhyolite precursors, and underlying plinian beds. They are distinct from countless, usually smaller volume, zoned rhyolite-dacite-andesite deposits that are conventionally believed to have erupted from magma chambers in which thermal and compositional gradients were established because of sidewall crystallization and associated convective fractionation. Despite their great volume, or because of it, monotonous intermediates have received little attention. Documentation of the stratigraphy, composition, and geologic setting of the Lund Tuff - one of four monotonous intermediate tuffs in the middle-Tertiary Great Basin ignimbrite province - provides insight into its unusual origin and, by implication, the origin of other similar monotonous intermediates. The Lund Tuff is a single cooling unit with normal magnetic polarity whose volume likely exceeded 3000 km 3. It was emplaced 29.02±0.04 Ma in and around the coeval White Rock caldera which has an unextended north-south diameter of about 50 km. The tuff is monotonous in that its phenocryst assemblage is virtually uniform throughout the deposit: plagioclase>quartz≈hornblende>biotite>Fe-Ti oxides≈sanidine>titanite, zircon, and apatite. However, ratios of phenocrysts vary by as much as an order of magnitude in a manner consistent with progressive crystallization in the pre-eruption chamber. A significant range in whole-rock chemical composition (e.g., 63-71 wt% SiO 2) is poorly correlated with phenocryst abundance. These compositional attributes cannot have been caused wholly by winnowing of glass from phenocrysts during eruption, as has been suggested for the monotonous intermediate Fish Canyon Tuff. Pumice fragments are also crystal-rich, and chemically and mineralogically indistinguishable from bulk tuff. We postulate that

    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.

    A new CAMAC based data acquisition system has been installed at the Lund Nuclear Microprobe facility. This paper reports on the development and present status of the data acquisition system. The system is a true multiparameter CAMAC based system with fast Fera bus readout and in crate memory buffer. The user interface is based on Sparrow Kmax software for a Power Macintosh platform. The system read out and tag the event data with position on-line, which make fast on-line monitoring of spectra or element maps possible.Simultaneously, all data can be saved event by event for off-line analysis. The beam scanning part is software controlled through a timed D/A converter, this allows fast scanning of the beam. With a CCD-camera and video card the area to be analysed could be defined directly from the image, and the sample position can be moved. Any kind of irregular scan patterns could be defined.

  1. Pharmaceutical expenditure in Sweden.

    1999-05-01

    Recently, the responsibility for prescribed pharmaceuticals in Sweden was transferred from national level to the regional health authorities (county councils). The purpose was that a closer integration and balance between pharmaceuticals and other factors of production in health care should produce better opportunities for a cost-effective use of the total health care resources. The purpose of this paper is to present a deeper analysis of pharmaceuticals as a production factor in Sweden, mainly during the 1990s, and to discuss the future development and future policy decisions in Sweden. Pharmaceuticals have increased their share of total health care expenditure in Sweden, from about 9% in 1990 to about 14% in 1995. The Swedish pharmaceutical market can be divided into sub-markets, where the prescription sub-market accounts for the greater part of pharmaceutical expenditure. Further, a few disease categories account for a larger fraction of the cost of prescribed pharmaceuticals. The importance of pharmaceuticals as a production factor also differs between different age groups. Several factors are expected to contribute to a future increase in Swedish pharmaceutical expenditure, for instance an ageing population and the rapid introduction of expensive new pharmaceuticals.

    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.

    In 1947 I became a second-year student at Moscow State University's Physics and Engineering Department, where a part of the week's classes were taught at base organizations. Our group's base was the future Kurchatov Institute, at that time known as the mysterious "Laboratory N^circ 2," and later as LIPAN. . Besides group lectures and practical work at the experimental laboratories, we also had access to the general seminars which Igor Vasilyevich Kurchatov tried to hold, with Leonid Vasilyevich Groshev filling in when he was absent. At the seminar, theorists spoke as welcome co-presenters and commentators. In 1949 I felt ready to approach A. B. Migdal to ask if I could transfer to his theoretical sector. In response, he suggested a number of simple qualitative problems, which I then successfully solved. (Incidentally, AB used the very same "introductory problems" for screening many generations of students.) So I wound up among AB's students. From 1952 on (for 10 years) I also served as an employee of the Migdal Sector. My memoirs here are mainly inspired by these years of constant communication with AB. After my departure for Novosibirsk in 1962, although our meetings still took place, they became occasional....

    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. PMID:26401795

  8. 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.

    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. PMID:26613624

    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. The current research activities at the Porphyria Centre which aim at finding ways to substitute the mutated gene in

    Life expectancy in Sweden is high and the country performs well in comparisons related to disease-oriented indicators of health service outcomes and quality of care. The Swedish health system is committed to ensuring the health of all citizens and abides by the principles of human dignity, need and solidarity, and cost-effectiveness. The state is responsible for overall health policy, while the funding and provision of services lies largely with the county councils and regions. The municipalities are responsible for the care of older and disabled people. The majority of primary care centres and almost all hospitals are owned by the county councils. Health care expenditure is mainly tax funded (80%) and is equivalent to 9.9% of gross domestic product (GDP) (2009). Only about 4% of the population has voluntary health insurance (VHI). User charges fund about 17% of health expenditure and are levied on visits to professionals, hospitalization and medicines. The number of acute care hospital beds is below the European Union (EU) average and Sweden allocates more human resources to the health sector than most OECD countries. In the past, the Achilles heel of Swedish health care included long waiting times for diagnosis and treatment and, more recently, divergence in quality of care between regions and socioeconomic groups. Addressing long waiting times remains a key policy objective along with improving access to providers. Recent principal health reforms over the past decade relate to: concentrating hospital services; regionalizing health care services, including mergers; improving coordinated care; increasing choice, competition and privatization in primary care; privatization and competition in the pharmacy sector; changing co-payments; and increasing attention to public comparison of quality and efficiency indicators, the value of investments in health care and responsiveness to patients needs. Reforms are often introduced on the local level, thus the pattern of

    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.

    In 1987, a survey of contraceptive use, knowledge and attitudes was conducted in Sweden by the International Health Foundation (IHF) as part of a multi-country study that has so far involved six other countries in Europe. The women involved, who were aged 15-44, completed a standard questionnaire. The overall percentage use of contraceptive methods, especially the reliable ones, was found to be high (95%). Oral contraception was the most frequently used method, followed by barrier methods and the intrauterine device (IUD). Contraceptive methods were chosen or abandoned mainly because of health reasons and better reliability. Knowledge of fertility proved to be generally good. Medical methods such as oral contraceptives and IUDs were associated with health hazards. In the case of the pill, fears of cardiovascular risks, thrombosis and cancer were widespread, while infection risk and menorrhagia were the most frequently quoted perceived disadvantages of the IUD. Indeed, these two methods suffer from a very negative image among Swedish users. PMID:2752752

    Objectives The use of electroconvulsive therapy (ECT) varies across countries. The aim of this study was to describe and explore the use of ECT in Sweden in 2013. Methods The Swedish mandatory patient register of the National Board of Health and Welfare includes information on diagnoses and treatments, including ECT. All 56 hospitals that provide ECT in Sweden also report to the nonmandatory national quality register for ECT, which contains information on patient and treatment characteristics. In this study, we combined data from both registers. In addition, all hospitals responded to a survey concerning equipment and organization of ECT. Results We identified 3972 unique patients who received ECT in Sweden in 2013. This translates into 41 ECT-treated individuals per 100,000 inhabitants. Of these patients, 85% opted to participate in the quality register. The median age was 55 years (range, 15–94 years), and 63% were women. The indication was depression in 78% of the treatment series. Of 4 711 hospitalized patients with severe depression, 38% received ECT. The median number of treatments per index series was 7. Unilateral treatment was used in 86% of the series. Conclusions In Sweden, ECT is used at a relatively high rate as compared with other western countries, and the rate was unchanged from the last survey in 1975. However, there is room for improvement in the specificity of use and availability of ECT for disorders where ECT is considered a first-line treatment. PMID:25973769

    Device simulations of (1) the laterally-contacted-unipolar-nuclear detector (LUND), (2) the SpectrumPlus, (3) and the coplanar grid made of Cd{sub 0.9}Zn{sub 0.1}Te (CZT) were performed for {sup 137}Cs irradiation by 662.15 keV gamma-rays. Realistic and controlled simulations of the gamma-ray interactions with the CZT material were done using the MCNP4B2 Monte Carlo program, and the detector responses were simulated using the Sandia three-dimensional multielectrode simulation program (SandTMSP). The simulations were done for the best and the worst expected carrier nobilities and lifetimes of currently commercially available CZT materials for radiation detector applications. For the simulated unipolar devices, the active device volumes were relatively large and the energy resolutions were fairly good, but these performance characteristics were found to be very sensitive to the materials properties. The internal electric fields, the weighting potentials, and the charge induced efficiency maps were calculated to give insights into the operation of these devices.

    Background We aimed to test the hypothesis that 3-D volume-based scoring of computed tomographic (CT) images of the paranasal sinuses was superior to Lund-Mackay CT scoring of disease severity in chronic rhinosinusitis (CRS). We determined correlation between changes in CT scores (using each scoring system) with changes in other measures of disease severity (symptoms, endoscopic scoring, and quality of life) in patients with CRS treated with triamcinolone. Methods The study group comprised 48 adult subjects with CRS. Baseline symptoms and quality of life were assessed. Endoscopy and CT scans were performed. Patients received a single systemic dose of intramuscular triamcinolone and were reevaluated 1 month later. Strengths of the correlations between changes in CT scores and changes in CRS signs and symptoms and quality of life were determined. Results We observed some variability in degree of improvement for the different symptom, endoscopic, and quality-of-life parameters after treatment. Improvement of parameters was significantly correlated with improvement in CT disease score using both CT scoring methods. However, volumetric CT scoring had greater correlation with these parameters than Lund-Mackay scoring. Conclusion Volumetric scoring exhibited higher degree of correlation than Lund-Mackay scoring when comparing improvement in CT score with improvement in score for symptoms, endoscopic exam, and quality of life in this group of patients who received beneficial medical treatment for CRS.

    During fieldwork carried out in January 2009 at Aurora do Tocantins (Tocantins State, northern Brazil), we recovered a fragmentary right maxilla (UNIRIO-PM 1006) of Catagonus stenocephalus from a sedimentary deposit of presumed late Pleistocene age in a karstic cave. This paper aims to: (1) provide the first record of C. stenocephalus in the northern region of Brazil (and consequently, also the northernmost one); (2) update the geographic distribution of C. stenocephalus; (3) present a date for the specimen; and (4) discuss the palaeoenvironmental and palaeobiogeographical implications of the finding. The species C. stenocephalus (Lund) is known from the Bonaerian (middle Pleistocene) and Lujanian (late Pleistocene to earliest Holocene) ages in Argentina, Uruguay, Brazil and Bolivia. The new record presented here extends the geographical distribution of C. stenocephalus more than 1000 km north from the former northernmost record (caves of Lagoa Santa region). Peccaries of the genus Catagonus have several morphological features associated with cursorial habits in relatively open and dry environments. The new distributional range of C. stenocephalus is coincident with the Chacoan subregion, characterized by dry climates and open areas. As the studied material comes from the top of the carbonate layer, this may suggest that the deposition of the C. stenocephalus remains described here is synchronous with the onset of a wetter climate phase. This argument is also in accordance with the datation results, around 20 ky BP, just after the last glacial maximum. This increasingly wet climate, which may also be related to the climatic changes that occurred during the late Pleistocene/early Holocene, could be a factor in the extinction of C. stenocephalus in South America.

    In Sweden, the prevalence of Trichinella infection in domestic pigs has greatly decreased since the 1970s, with no reports in the past 4 years. However, infected wild animals continue to be found. The objective of the present study was to identify the species of Trichinella present in animals of Sweden, so as to contribute to the knowledge on the distribution area and hosts useful for the prevention and control of this zoonosis. In the period 1985-2003, Trichinella larvae were detected in the muscles of 81/1800 (4.5%) red foxes (Vulpes vulpes), 1/6 (16.7%) arctic fox (Alopex lagopus), 1/7 (14.3%) wolf (Canis lupus), 10/200 (5.0%) lynxes (Lynx lynx), 4/8000 (0.05%) wild boars (Sus scrofa), and 27/66 x 10(6) (0.000041%) domestic pigs. All four Trichinella species previously found in Europe were detected (Trichinella spiralis, T. nativa, T. britovi and T. pseudospiralis). The non-encapsulated species T. pseudospiralis was detected in three wild boars from Holo (Stockholm area) and in one lynx from Froso (Ostersund area), suggesting that this species is widespread in Sweden. These findings are consistent with those of a study from Finland, both for the unexpected presence of T. pseudospiralis infection and the presence of the same four Trichinella species, suggesting that this epidemiological situation is present in the entire Scandinavian region. The widespread diffusion of T. pseudospiralis in the Scandinavian region is also important in terms of it potential impact on public health, given that human infection can occur and the difficulties to detect it by the trichinelloscopic examination.

    Undergraduate students associated with The George Washington University and UMass Dartmouth have had the opportunity to participate in nuclear physics research as a part of the PIONS@MAXLAB Collaboration performing experiments at MAX-lab at Lund University in Sweden. This project has supported thirteen undergraduate students during 2009 - 2011. The student researchers are involved with all aspects of the experiments performed at the laboratory, from set-up to analysis and presentation at national conferences. These experiments investigate the dynamics responsible for the internal structure of the nucleon through the study of pion photoproduction off the nucleon and high-energy Compton scattering. Along with the US and Swedish project leaders, members of the collaboration (from four different countries) have contributed to the training and mentoring of these students. This program provides students with international research experiences that prepare them to operate successfully in a global environment and encourages them to stay in areas of science, technology, engineering and math (STEM) that are crucial for our modern, technology-dependent society. We will present the history, goals and outcomes in both physics results and student success that have come from this program. This work supported by NSF OISE/IRES award 0553467.

    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.

    Sweden enjoys a good doctor and specialist obstetrician and gynaecologist to population ratio. The medical education for 5.5 years is state funded. The specialist training period is flexible but 5 years is a minimum. The head of department takes the responsibility of assessing and certifying the physician based on completion of the training objectives. There is a voluntary examination by Swedish Society of Obstetrics and Gynaecology. The university hospitals accept those who combine specialist training with research. The research programme has to be approved by the faculty and should lead to a doctoral degree by a thesis. Those who are trained in a non-university hospital are virtually guaranteed continued employment while those from the university hospitals have to apply for a position. There are many applicants to each post and they are judged by an internal and external panel based on the attributes of research, teaching and administrative skills. PMID:10718722

    A hierarchical, modular modeling environment for hybrid simulations of sequential-modular, systems dynamics, discrete-event, and agent-based paradigms Omega-AB models contain a hierarchically-defined module tree that specifies the execution logic for the simulation, and a multi-network graph that defines the environment within which the simulation occurs. Modules are the fundamental buildinig blocks of an Omega-AB model and can define anything from a basic mathematical operation to a complex behavioral response model. Modules rely on the "plug-in" conceptmore » which allows developers to build independent module libraries that are gathered, linked, and instantiated by the Omega-AB engine at run time. Inter-module communication occurs through two complimentary systems: pull-based "ports" for general computation patterns and push-based "plugs" for event processing. The simulation environment is an abstract graph of nodes and links. Agents (module sub-trees headed up by an Agent module) reside at nodes and relate to their neighbors through typed links. To facilitate the construction and visualization of complex, interacting networks with dramatically different structure, Omega-AB provides a system for organizing the nodes into hierarchica trees that describe "slices" of the overall network.« less

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

    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. PMID:23527451

    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. PMID:21470451

    After investigating a number of materials, we discovered that an ABS plastic doped with a conducting polymer performs well as the resistive electrode in a narrow gap RPC (resistive plate chamber). Operating in the streamer mode, we find efficiencies of 90-96% with low noise and low strip multiplicities. We have also studied a variety of operating gases and found that a mixture containing SF{sub 6}, a non-ozone depleting gas, argon and isobutane gives good streamer mode performance, even with isobutane concentrations of 20% or less.

    Acreo in Sweden has been invovled in Quantum Well IR Photodetector (QWIP) reserach and development since 1986. During the first years a small group led by Jan Andersson was dedicated to research on QWIP structures and means of coupling radiation into the quantum-well structure. One of the resarech results is a 2D optical grating couler to create an optimal elecgtric field pattern for highest possible absorption and responsivity. Acreo holds a patent for this grating coupler. Since 1988 FLIR Systems, later FMV, Saab Dynamics, Celsius Tech and NUTEK have sponsoered an R and D project with the goal to develop QWIP detectors and start up production. Soon it became clear that an adapted ROIC deisng and the hybridization of the focal plane array are key issues in order to achieve the highest possible performance and operability of the complete detector device for voluem production. Extended measures where taken in 1996. In 1997 the industrial interest increased further, ClesiusTech and Saab Dynamics, merged in 2000, and now a division of FLIR Systems AB started to sponsor the R and D project. Because of its success during the last years it has now been expanded and scheduled until 2003 and beyond. Volume production of QWIP FPAs started in 2000.

  12. A new approach to identify the sensitivity and importance of physical parameters combination within numerical models using the Lund-Potsdam-Jena (LPJ) model as an example

    NASA Astrophysics Data System (ADS)

    Sun, Guodong; Mu, Mu

    2016-01-01

    An important source of uncertainty, which causes further uncertainty in numerical simulations, is that residing in the parameters describing physical processes in numerical models. Therefore, finding a subset among numerous physical parameters in numerical models in the atmospheric and oceanic sciences, which are relatively more sensitive and important parameters, and reducing the errors in the physical parameters in this subset would be a far more efficient way to reduce the uncertainties involved in simulations. In this context, we present a new approach based on the conditional nonlinear optimal perturbation related to parameter (CNOP-P) method. The approach provides a framework to ascertain the subset of those relatively more sensitive and important parameters among the physical parameters. The Lund-Potsdam-Jena (LPJ) dynamical global vegetation model was utilized to test the validity of the new approach in China. The results imply that nonlinear interactions among parameters play a key role in the identification of sensitive parameters in arid and semi-arid regions of China compared to those in northern, northeastern, and southern China. The uncertainties in the numerical simulations were reduced considerably by reducing the errors of the subset of relatively more sensitive and important parameters. The results demonstrate that our approach not only offers a new route to identify relatively more sensitive and important physical parameters but also that it is viable to then apply "target observations" to reduce the uncertainties in model parameters.

  13. Geomorphology of intraplate postglacial faults in Sweden

    2015-12-01

    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

    2016-03-01

    With the recent advances towards modern Ion Beam Analysis (IBA), going from one- or few-parameter detector systems to multi-parameter systems, it has been necessary to expand and replace the more than twenty years old CAMAC based system. A new VME multi-parameter (presently up to 200 channels) data acquisition and control system has been developed and implemented at the Lund Ion Beam Analysis Facility (LIBAF). The system is based on the VX-511 Single Board Computer (SBC), acting as master with arbiter functionality and consists of standard VME modules like Analog to Digital Converters (ADC's), Charge to Digital Converters (QDC's), Time to Digital Converters (TDC's), scaler's, IO-cards, high voltage and waveform units. The modules have been specially selected to support all of the present detector systems in the laboratory, with the option of future expansion. Typically, the detector systems consist of silicon strip detectors, silicon drift detectors and scintillator detectors, for detection of charged particles, X-rays and γ-rays. The data flow of the raw data buffers out from the VME bus to the final storage place on a 16 terabyte network attached storage disc (NAS-disc) is described. The acquisition process, remotely controlled over one of the SBCs ethernet channels, is also discussed. The user interface is written in the Kmax software package, and is used to control the acquisition process as well as for advanced online and offline data analysis through a user-friendly graphical user interface (GUI). In this work the system implementation, layout and performance are presented. The user interface and possibilities for advanced offline analysis are also discussed and illustrated.

    Sweden has been spared from wars and similar disasters for almost two centuries, and over the years the population and politicians have been lulled into the belief that "it'll never happen". This has affected the ability of the medical system to respond adequately to the enormous demands that a war would make upon us. The geographical and political situation and the basic facts about Swedish health care are briefly sketched. After a review of the history of anesthesia in war, current medical planning for war or similar disaster situations in Sweden is outlined and its weaknesses mentioned. A program is presented that aims at improving the situation in anesthesia manpower, postgraduate training and equipment. The expanded role of the already highly skilled and independent Swedish corps of nurse anesthetists (RNA's) is outlined, especially in the field of regional anesthesia. Standardized methods for anesthesia in war also are presented. The aim is to make optimal use of existing resources and enable patients to be transferred immediately postoperatively to understaffed wards. PMID:2773630

The Department of Space Science is a joint department between the two most northern universities in Sweden, Luleå University of Technology and Umeå University in collaboration with the Swedish Institute of Space Physics. It offers a range of education programmes in the space field. There are bachelor and master programmes in space engineering, and a bridging programme for students without a science background from secondary school. The Department also contributes to courses for teachers, Ph.D. courses and secondary school level courses. One master's program and a three week summer course are given entirely in English and welcome international students. Thanks to good cooperation with Esrange students can build and fly experiments on high altitude balloons and sounding rockets and also take a large responsibility for the management of the projects. Close interaction with research and industry is an important part of the education.

  8. 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

    SciTech Connect

    Dufva, B.

    1988-01-01

    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.

    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.

    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

    Using the Cancer-Environment Registry, which links the incidence of cancer (1961-79) and the 1960 census data on industry and occupation for all employed individuals in Sweden, the occurrence of biliary tract cancer (ICD 7th rev 155.1-.9) was systematically assessed according to occupational and industrial classifications. Data are presented separately for cancer of the gall bladder (ICD 155.1) and other cancers of the biliary tract (ICD 155.2-.9) including cancers of the extrahepatic bile ducts, ampulla of Vater, and unspecified bile passages. Statistically significant increased risks for cancer of the gall bladder were observed for men employed in petroleum refining, papermills, chemical processing, shoemaking, and repairing, and for both men and women employed in textile work. A significant increase in the incidence of other cancers of the biliary tract (mostly cancers of the bile duct) was found for such asbestos related employment as shipbuilding and in the wholesale construction materials industry and among insulation workers. These findings should be considered only as clues to aetiological factors, although several are consistent with earlier observations from other countries. PMID:3964574

    Background: A high prevalence of sickness absence in many countries, at a substantial societal cost, underlines the importance to understand its determining mechanisms. This study focuses on the link between relative deprivation and the probability of sickness absence. Methods: 184,000 men and women in Sweden were followed between 1982 and 2001. The sample consists of working individuals between the ages of 19 and 65. The outcome is defined as experiencing more than 14 days of sickness absence during a year. Based on the complete Swedish population, an individual’s degree of relative deprivation is measured through income compared to individuals of the same age, sex, educational level and type. In accounting for the possibility that sickness absence and socioeconomic status are determined by common factors, discrete-time duration models were estimated, accounting for unobserved heterogeneity through random effects. Results: The results confirm that the failure to account for the dynamics of the individual’s career biases the influence from socioeconomic characteristics. Results consistently suggest a major influence from relative deprivation, with a consistently lower risk of sickness absence among the highly educated. Conclusions: Altering individual’s health behavior through education appears more efficient in reducing the reliance on sickness absence, rather than redistributive policies. PMID:23996012

    Ab initio electronic structure methods can supplement CALPHAD in two major ways for subsequent applications to stability in complex alloys. The first one is rather immediate and concerns the direct input of ab initio energetics in CALPHAD databases. The other way, more involved, is the assessment of ab initio thermodynamics {acute a} la CALPHAD. It will be shown how these results can be used within CALPHAD to predict the equilibrium properties of multi-component alloys.

    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.

  20. Ab initio nuclear structure theory

    NASA Astrophysics Data System (ADS)

    Negoita, Gianina Alina

    Ab initio no core methods have become major tools for understanding the properties of light nuclei based on realistic nucleon-nucleon (NN) and three-nucleon (NNN) interactions. A brief description is provided for the inter-nucleon interactions that fit two-body scattering and bound state data, as well as NNN interactions. Major new progress, including the goal of applying these interactions to solve for properties of nuclei, is limited by convergence issues. That is, with the goal of obtaining high precision solutions of the nuclear many-body Hamiltonian with no core methods (all nucleons treated on the same footing), one needs to proceed to very large basis spaces to achieve a convergence pattern suitable for extrapolation to the exact result. This thesis investigates (1) the similarity renormalization group (SRG) approach to soften the interaction, while preserving its phase shift properties, and (2) adoption of a realistic basis space using Woods-Saxon (WS) single-particle wavefunctions. Both have their advantages and limitations, discussed here. For (1), SRG was demonstrated by applying it to a realistic NN interaction, JISP16, in a harmonic oscillator (HO) representation. The degree of interaction softening achieved through a regulator parameter is examined. For (2), new results are obtained with the realistic JISP16 NN interaction in ab initio calculations of light nuclei 4He, 6He and 12C, using a WS basis optimized to minimize the ground-state energy within the truncated no core shell model. These are numerically-intensive many-body calculations. Finally, to gain insight into the potential for no core investigations of heavier nuclei, an initial investigation was obtained for the odd mass A = 47 - 49 region nuclei straddling 48Ca. The motivation for selecting these nuclei stems from the aim of preparing for nuclear double beta-decay studies of 48Ca. In these heavier systems, phenomenological additions to the realistic NN interaction determined by previous

  5. Ionic composition and mineral equilibria of acidic groundwater on the west coast of Sweden

    Sjoestroem, J.

    1993-08-01

    The groundwater chemistry of 14 shallow wells and 10 springs in Halland, southwest Sweden, and precipitation have been studied in trilinear diagrams. Ionic strength and saturation index (SI) for selected minerals have been calculated. Five springwaters have similar chemical composition to that of the precipitation, which indicates surficial and rapidly recharged water. The SI of the groundwaters is out of equilibrium (undersaturated) with respect to primary silicates such as mafic minerals, feldspar, K-mica and chlorite, but in equilibrium with solid SiO{sub 2} (quartz, cristobalite, or chalcedony). The SI shows oversaturation conditions for kaolinite, hydroxy-Al interlayered vermiculite, Na, K, Mg-beidellite, Mg-montmorillonite, and AB-montmorillonite. Concentrations of soluble Al and Si can be governed by Mg, Fe-beidellite, BF-montmorillonite, or Ca-montmorillonite at four springs, and by halloysite at two wells on the coastal plain. For these groundwaters, clay minerals may act as H{sup +} buffers and thus have an influence on pH and toxic Al, i.e., parameters affecting the drinking water quality and environment. The study shows that the soil catena are intensily weathered at the investigated sites. It is further concluded that neither cation exchange nor primary silicate weathering will keep up with buffering the acidic loads into the soils. A general prediction of groundwater quality is presented. 23 refs., 4 figs., 4 tabs.

  6. 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.

    Recent research is focused on superlattices arising from optical lattices, which allow a tunable environment. Experimentally bosons present transitions from superfluid to Mott insulator by changing the energy offset in the unit cell [Nat. Commun. 5:5735 (2014)]. Many studies displayed that ground state of spinless boson systems on superlattices present superfluid, Mott insulator and an additional CDW phase created by the energy shift between the sites into the unit cell [Phys. Rev. A 83, 053621 (2011)]. The first confinement methods were magnetic traps, which freezes the spin; with optical lattices the grade of freedom of spin plays an important role. We consider bosons with spin S =1 on a superlattice made by two sites with energy offset per unit cell (AB chain). The Hamiltonian that describes the system is the Bose-Hubbard model with the superlattice potential (W) and the exchange interaction (V) parameters. This model supports CDW, Mott insulator and superfluid phases. For W near to U, with V =0, Mott phase disappears, but for V increasing, a new CDW appears due to the spin interaction, while the half-integer CDW decrease. These results are widely different from spinless boson, where the CDW phases are stables.

    We utilize MPP and vector computers to model the interaction of large sulfur-containing species bonded with hydrodesulfurization (HDS) catalysts. This work is made possible by the availability large aggregate memory, parallel computers. The ability of modern non-traditional computers to solve large-scale scientific problems has been demonstrated. This success is accomplished, in part, by access to portable low- and user-level software tools which exhibit good control over NUMA. ab initio SCF methods are used to characterize the energies of adsorption of poly-aromatic, sulfur-containing hydrocarbons onto a series of molecular-based models of MoS2. These hydrocarbon include thiophene (TP), benzothiophene (BT) and dibenzothiophene (DBT) which are representative of heavy crude feedstocks. Our work attempts to ascertain if a consistent model of adsorption onto a MoS2 surface exists and to determine how the electronic and steric configuration of each species affect their energies of interaction with the metal surface.

  9. GINGA Observations of AB Doradus

    We report GINGA observations of the pre main sequence star AB Doradus (HD 36705), performed during 8 - 12 January, 1990. Some rotational modulation might be present. four X-ray flares were detected. Three of these events were similar to the EINSTEIN HRI-flare (Vilhu and Linsky, 1987), with decay times around 25 min. The last flare had long rise and decay times (100 min), resembling the EXOSAT flares observed by Collier Cameron et.al. (1988). The mean flare spectrum can be fitted by a thermal bremstrahlung with temperature 5.0 keV, or by a power-law model with photon index 2.2. The 3 upper limit of the Iron line equivalent width in the flare spectrum is 1 keV, weaker than predicted by thermal models. This Iron line anomaly was first discussed in the case of UX Ari by Tsuru et. al. (1989). However, normal equivalent widths can be derived from several EXOSAT spectra of active cool stars (Pallavicini and Tagliaferri, 1990). We discuss the possibility that the continuum from non-thermal electrons (producing also the microwave emission) could occasionally lower the apparent equivalent width. The mechanism works for reasonably low magnetic field strengths and electon power-law indexes. However, a large population of non-thermal electrons is needed (comparable to the thermal one). Stronger magnetic fields could explain the radio emission with less electrons, but then the non-thermal X-ray continuum remains small.

    B AB AR, the detector for the SLAC PEP-II asymmetric e +e - B Factory operating at the ϒ(4 S) resonance, was designed to allow comprehensive studies of CP-violation in B-meson decays. Charged particle tracks are measured in a multi-layer silicon vertex tracker surrounded by a cylindrical wire drift chamber. Electromagnetic showers from electrons and photons are detected in an array of CsI crystals located just inside the solenoidal coil of a superconducting magnet. Muons and neutral hadrons are identified by arrays of resistive plate chambers inserted into gaps in the steel flux return of the magnet. Charged hadrons are identified by d E/d x measurements in the tracking detectors and by a ring-imaging Cherenkov detector surrounding the drift chamber. The trigger, data acquisition and data-monitoring systems, VME- and network-based, are controlled by custom-designed online software. Details of the layout and performance of the detector components and their associated electronics and software are presented.

    Gerdtham, U G; Jönsson, B

    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

    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

    Through ab initio approaches in nuclear theory, we may now seek to quantitatively understand the wealth of nuclear collective phenomena starting from the underlying internucleon interactions. No-core configuration interaction (NCCI) calculations for p-shell nuclei give rise to rotational bands, as evidenced by rotational patterns for excitation energies, electromagnetic moments and electromagnetic transitions. In this review, NCCI calculations of 7-9Be are used to illustrate and explore ab initio rotational structure, and the resulting predictions for rotational band properties are compared with experiment. We highlight the robustness of ab initio rotational predictions across different choices for the internucleon interaction.

    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.

    During summer 2014, a total of 89 Vibrio infections were reported in Sweden and Finland, substantially more yearly infections than previously have been reported in northern Europe. 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

    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. PMID:26924220

  12. Contemporary relevance of Rokliden, Sweden's first forest hydrology field study

    2015-04-01

    During the last decades of the 19th century a great worry arose about forest landscape paludification in Northern Sweden. This was the original impetus for forest hydrological research in Sweden and the Swedish Institute of Experimental Forestry established the first field research site in 1905 at Rokliden, close to Piteå in North Sweden. It comprised 8.64 ha located 2 km down a 3 km long gently sloping (ca 4%), north facing Norway spruce covered till slope, interspersed with small mires. By 1931 it was concluded that paludification was not spreading across Northern Sweden at an appreciable rate. Within the Rokliden research site 22 groundwater wells were installed and levels measured weekly until 1926. A map with 0.5 m equidistance, 10 vegetation classes, and soil profiles was established. A limited forest harvest was done in 1908, but significant effects on groundwater levels were not found. Groundwater flow velocity was estimated by tracing added sodium chloride. Hydraulic conductivity was measured on undisturbed soil cores, while mechanical and chemical analyses were done on other samples. Groundwater was collected and analyzed for dissolved compounds including oxygen. Hydrology was found important for soil types and vegetation development. The necessary profile drainage for podzol soil development was identified as vein drainage at the bedrock surface. The low lateral hydraulic gradient in the gentle slopes and the low hydraulic conductivity in the deeper till soil made lateral flow much smaller than required. The vein drainage was a perfect solution to the problem and great effort was put into showing the existence and importance of veins. Modern measurements in the re-established groundwater observation network and re-analysis of old data confirmed the plausibility of these original conclusions. Partial catchment area could explain rates of both groundwater level rise and recession. Revisiting this field study reveals that many issues in contemporary

    As humans alter landscape, vegetation, climate and atmospheric composition, changes in the terrestrial water balance and fresh water resources are likely to occur. Understanding how climate, vegetation, humans and hydrology interact is key for accurate projections of future fresh water resources. In this study we focus on forest dominated Sweden where significant changes in climate and increasing human activity have co-occurred during the past 50 years. For 280 catchments in Sweden, we related runoff coefficients and change trends thereof to land-surface characteristics. With these relationships we created average and change trend maps for runoff and evapotranspiration across Sweden. All this information is summarized by plotting water use efficiency (actual evapotranspiration (ET)/precipitation) against energy use efficiency (actual ET/potential ET ) in a Budyko-type framework for areas with unique land cover across Sweden. This plot clearly shows that wetlands tend to have lower water and energy use efficiencies compared to 'open waters', forests and agriculture, and that agriculture and forests have comparable water and energy use efficiencies closest to those of 'open waters'. These results demonstrate how a change in land cover driven by climate change or by humans is likely to alter land-cover-atmosphere interactions, thereby changing both the water and energy balance of catchments. Looking at runoff coefficient change trends during the last 50 years we see that forests tended to become more efficient in using water and energy (i.e. the fractions of water and energy converted into river runoff and heat decreased). As this behavior coincides with an increase in precipitation it signals an acceleration of the hydrological cycle of Swedish forests. In this presentation we will discuss these findings focusing on the impact of forests on river discharges and the implications for future water cycles.

  15. Cancer risks in Nordic immigrants and their offspring in Sweden.

    2002-12-01

    Numerous migrant studies on cancer have been carried out, but little data are available on cancer incidence upon inter-European migration. We used the nationwide Swedish Family-Cancer Database to analyse cancer risk among Nordic immigrants and their offspring in Sweden. The parental population had entered Sweden in their 20s and they had become parents in Sweden. Finns were the largest immigrant group including approximately 183,000 parents and 278,000 offspring. We calculated the standardised incidence ratios (SIRs) and 90 or 95% confidence intervals (CIs) for 26 cancer sites using native Swedes as a reference. Cancers in the first generation immigrants followed the rates in the countries of origin, reaching high SIRs for tobacco-related, cervical and testicular cancer among Danes and for stomach cancer among Finns. Only a few cancers, such as cervical cancer was increased in the second generation. At many sites, particularly among the Finns, protection was observed in the first generation. At three sites, breast, ovary and urinary bladder, where plausible evidence for protection was found even among offspring, this was not reinforced among the offspring of compatriot parents, which is inconsistent with heritable effects. Protection against melanoma was strongest among the offspring of compatriots, but the contribution of cultural factors cannot be excluded. As the parents immigrated to Sweden in their 20s, their cancer pattern, including habits and life style, appeared to be set before that age because the differences to Swedes persisted even in cancers that predominate in old age. Immigrant populations would appear to be attractive subjects to study etiological factors of cancer at sites where causes remain poorly understood, such as testicular cancer. PMID:12460788

    1977-01-01

    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

    Hemminki, Kari; Li, Xinjun

    We used the nationwide Swedish Family-Cancer Database to analyze cancer risks in Sweden-born descendants of immigrants from European and North American countries. Our study included close to 600,000 0-66-year-old descendants of an immigrant father or mother. We calculated standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for 17 cancer sites using native Swedes as a reference. All cancer was marginally below the Swedish incidence in offspring of immigrant origin. Decreased SIRs were observed for breast cancer among Norwegian descendants, melanoma among descendants of Hungarian fathers and ovarian and bladder cancer among descendents of Finnish mothers, all consistent with the difference in cancer incidence between Swedes and the indigenous populations. Cervical cancer was increased in daughters of Danish men, whereas thyroid cancer and non-Hodgkin's lymphoma were in excess in offspring of parents of Yugoslav and Asian descent. Even these results agreed with the high incidence rates in parents compared to Swedes, except that for non-Hodgkin's lymphoma other explanations are needed; these may be related to immune malfunction. Comparison of the results between the first- and the second-generation immigrants suggest that the first 2 decades of life are important in setting the pattern for cancer development in subsequent life. Birth in Sweden sets the Swedish pattern for cancer incidence, irrespective of the nationality of descent, while entering Sweden in the 20s is already too late to influence the environmentally imprinted program for the cancer destiny.

    Background and purpose The incidence of knee osteoarthritis will most likely increase. We analyzed historical trends in the incidence of knee arthroplasty in Sweden between 1975 and 2013, in order to be able to provide projections of future demand. Patients and methods We obtained information on all knee arthroplasties in Sweden in the period 1975–2013 from the Swedish Knee Arthroplasty Register, and used public domain data from Statistics Sweden on the evolution of and forecasts for the Swedish population. We forecast the incidence, presuming the existence of a maximum incidence. Results We found that the incidence of knee arthroplasty will continue to increase until a projected upper incidence level of about 469 total knee replacements per 105 Swedish residents aged 40 years and older is reached around the year 2130. In 2020, the estimated incidence of total knee arthroplasties per 105 Swedish residents aged 40 years and older will be 334 (95% prediction interval (PI): 281–374) and in 2030 it will be 382 (PI: 308–441). Using officially forecast population growth data, around 17,500 operations would be expected to be performed in 2020 and around 21,700 would be expected to be performed in 2030. Interpretation Today’s levels of knee arthroplasty are well below the expected maximum incidence, and we expect a continued annual increase in the total number of knee arthroplasties performed.

    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.

    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.

    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.

    The formation of undesired high molecular weight species such as dimers is an important quality attribute for therapeutic monoclonal antibody formulations. Therefore, the thorough understanding of mAb dimerization and the detailed characterization mAb dimers is of great interest for future pharmaceutical development of therapeutic antibodies. In this work, we focused on the analyses of different mAb dimers regarding size, surface properties, chemical identity, overall structure and localization of possible dimerization sites. Dimer fractions of different mAbs were isolated to a satisfactory purity from bulk material and revealed 2 predominant overall structures, namely elongated and compact dimer forms. The elongated dimers displayed one dimerization site involving the tip of the Fab domain. Depending on the stress applied, these elongated dimers are connected either covalently or non-covalently. In contrast, the compact dimers exhibited non-covalent association. Several interaction points were detected for the compact dimers involving the hinge region or the base of the Fab domain. These results indicate that mAb dimer fractions are rather complex and may contain more than one kind of dimer. Nevertheless, the overall appearance of mAb dimers suggests the existence of 2 predominant dimeric structures, elongated and compact, which are commonly present in preparations of therapeutic mAbs.

  3. Sweden's population grows, Swedish population doesn't.

    The example of Swedish demography offers a contemporary insight into population growth or decline. In addition to the numerical increase due to the arrival of immigrants, migration can have an indirect effect on a country's population growth due to the arrived immigrants' subsequent natural fertility. Some very interesting differences also can often be observed in the births and deaths between the native born and immigrant populations. This phenomenon is particularly striking in the case of Sweden. In 1970 Sweden's population was growing at nearly 1% per year (9.83/1000), a relatively rapid pace by today's standard. Since 1970, the growth rate dropped steadily, down to only 0.1% in 1981. The main reason for the slowed population growth has been the decline in the birthrate, from 14/1000 population to the 11.3-11.7 range since 1976. At the same time, the death rate rose from 10 to 11. Gains in life expectancy have been outweighed by the increasing proportion of the elderly. During the 1970s the rate of net migration fluctuated considerably. It dropped from a high rate of 6/1000 in 1970 to -1.5 in 1972. 1972 and 1973 are the only postwar years in which Sweden experienced a net outflow. The rate rose again to 2.89 in 1977, falling to 0.3 in 1981, the latest year for which data are available. Starting in 1975 the components of Sweden's population change began to exhibit a remarkable aspect: population growth due to migration exceeded that due to natural increase. This had not occurred previously. Close examination reveals that the gain due to natural increase had become dependent upon the natural increase of the immigrants. Births of Swedish citizens, which had exceeded deaths by 22,000 in 1971, fell until natural decrease appeared in 1976. That gap has been growing wider ever since, to -6100 in 1982. A growing number of immigrants have been attaining Swedish citizenship, but the category of "citizen" is still the virtual equivalent of "native born." At the end of 1981

    Objectives The increased incidence of multiple myeloma (MM) across China and East Asia stimulated us to examine the current rates in Great Britain, where rates increased dramatically in the second half of the 20th century. However, rates have been stable and high during this period in Malmö, Sweden, where there is a keen interest in MM. We thus assessed recent changes in MM incidence in Great Britain, Sweden overall, and Malmö, Sweden, and examined how these changes might explain recent reports of increased MM incidence across Asia. Design Estimation of MM incidence for Great Britain, Sweden overall, and Malmö, Sweden. Populations MM incidence data for Great Britain (1975–2009) were obtained from Cancer Research UK and for Sweden (1970–2009) from the Swedish Cancer Registry. MM incidence data from Malmö, Sweden, were available from 1950 to 2012. Main outcome measures Age-specific incidence of MM in Great Britain, Sweden overall, and Malmö, Sweden. Results MM incidence in Great Britain, Sweden overall, and Malmö increased progressively with age, even among the oldest group. The MM age-adjusted incidence (European standard population) increased by 69% from 1975–1979 to 2005–2009 in Great Britain, from 3.2/100 000 to 5.4/100 000. The largest increases occurred among those 70–79 years of age, for whom rates increased from 17.9/100 000 to 33.6/100 000; reflecting an increase of 69%. During this same period, the age-adjusted incidence (European stand population) in Sweden overall remained stable, at approximately 4.7/100 000. Conclusions MM age-specific incidence is now similar in Great Britain, Sweden overall, and Malmö. We believe this is a result of improvements in case ascertainment in Great Britain, particularly among the elderly. Similar changes can be predicted to occur across Asia as improved access to healthcare contributes to better diagnosis of MM. PMID:26801465

    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.

  6. Fighting antibiotic resistance in Sweden--past, present and future.

    Sweden has been in the favorable situation of having limited antibiotic resistance and low antibiotic consumption. When pneumococci with reduced susceptibility to penicillin and methicillin-resistant Staphylococcus aureus emerged during the 1990s, professionals and relevant authorities called for extensive action plans to avoid the critical threshold levels of resistance experienced in other countries. The purpose of this paper is to examine Swedish experiences in light of new and future challenges by reviewing Swedish data on antibiotic resistance and antibiotic use, notifications, outbreak control, action plans and scientific papers. The tradition of liberal performance of clinical cultures, together with well functioning diagnostic laboratories, has formed a basis for close collaboration and development of surveillance within quality assurance programs. For more than 20 years the pharmacy monopoly in Sweden has made it possible to collect well defined data on antibiotic sales at the county level with almost 100% coverage. Multisectorial collaboration was set up in regional Strama (Swedish Strategic Programme Against Antibiotic Resistance) groups. Large diagnosis-prescribing surveys have been undertaken, and the concept of basic hygiene precautions was introduced, together with extensive programs for early case finding. However, surveillance has been hampered by inadequate IT systems and some difficulties in collecting relevant data on antibiotic sales at the national level. Also, a decentralized system with 21 counties and regions has resulted in divergence of action plans and rules. The containment of antibiotic resistance thus far may be explained by the early response in human and veterinary medicine and close multisectorial collaboration, supported by the government, before problems got out of hand. Nevertheless, rapidly growing problems with bacteria that produce extended beta-lactamases have recently emerged and antibiotic sales have started to increase

    The boundary between the Pleistocene/Holocene epochs was placed at 10,000 C(14) years B.P. (Libby half time) by the Holocene Commission. In search of a stratotype locality three cores from the province of Bohusian, south-western Sweden, were scrutinized concerning different geophysical, geochemical and bioastratigraphical parameters. The marine sequences of the cores from Moltemyr and Solberga reveal a distinct boundary and a transition zone respectively which meet the requirements laid down by the Holocene Commission. The suggested age of the lithological boundary is c. 10,200-10,300 years B.P.

    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.

    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.

    Invasive prenatal diagnosis was introduced in Sweden in the early 1970s and is an integral part of the public health care system. Funding is provided by taxation; the patient only pays a consultation fee. Genetic analyses on a broad range of cytogenetic and molecular disorders are performed at the 6 university-affiliated hospitals and in 1 county hospital. About 6% of all newborns have been cytogenetically screened during pregnancy, and about 90% of the analyses are performed after amniocentesis. The main indication is chromosome analysis because of advanced maternal age. PMID:9101184

    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

    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.

    Two genes were identified in Bacillus thuringiensis Berliner (Bt) that code for the proteins that comprise a Cry34Ab1/Cry35Ab1 binary insecticidal crystal protein. Maize, Zea mays L., plants have been transformed to express the Cry34Ab1/Cry35Ab1 proteins, and as a result, these plants are resistant to attack by western corn rootworm, Diabrotica virgifera virgifera LeConte, a major pest in the Midwestern corn-growing area of the U.S.A. As part of the safety assessment for the proteins, digestibility studies were conducted. Digestion experiments with both proteins demonstrated rapid degradation in simulated gastric fluid, comparable to other registered plant-incorporated protectants. Quantitative and qualitative approaches for determining digestibility are illustrated. PMID:14582981

    Swedish participation in the international efforts to measure the transits of Venus in the 1760s was impressive considering the size and the relative youth of the mathematical and astronomical community in the country. In this paper it is argued that the relative success of the Swedish contribution may be seen as the result of an early-modern form of research policy. This policy was promoted by the progressive so-called Hat Party that came into power in the late 1730s, an event that coincided with the creation of the Swedish Royal Academy of Sciences in Stockholm, soon to emerge as an organizational hub of astronomical research in Sweden and to some extent also on the European level. The close connection between the scientific and political elites in Enlightenment Sweden made possible the creation and international integration of a Swedish research community, not least in astronomy under the leadership of the Academy's perpetual secretary and astronomer Pehr Wargentin. The fact that these elites shared a common fate is also illustrated by their simultaneous decline from around 1770.

    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. PMID:25529978

    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

    2012-03-01

    This report covers a millennium, from year 1000 when Sweden had only 0.4 million people until today's 9.4 million. In the 13th century, the first Swedish legal text about the mentally ill and the first hospital to treat them are documented. Control, care and cure of the ill have been shaped by social and cultural changes from time to time, e.g. King Gustav Vasa introduced a paradigm shift of care after the Reformation, when he altered Catholic buildings into state hospitals. He also ordered that medical texts should no longer be written in Latin but in Swedish. The first book dealing with mental illnesses was published in 1578. Laypersons ran the mental hospitals for centuries until the medical perspective and doctors were engaged in the 1800 s. To advance the hospital doctors' competence and skill, a Swedish Psychiatric Association was established in 1905. Severely psychotic patients could not be effectively treated until the introduction of chlorpromazine in the 1950s and there is still no cure available. Following the deinstitutionalization, from more than 35,000 beds 50 years ago down to about 4500 today, the request for outpatient treatment increased. Mandatory training in psychotherapies for all psychiatrists started in the 1970s. A major "psychiatry reform", with the hope of improving the situation for the mentally ill, and to reduce the stigma, was introduced in Sweden in 1995. The historic long-term effect of the reform cannot yet be fully evaluated. PMID:21770823

    In this study the stroke characteristics of positive cloud-to-ground flashes in Sweden were obtained from the electric field records measured from 14 thunderstorms. The electric fields were measured with nanosecond resolution. Together with the fast and the slow electric field records, the narrowband radiation field at 3 and 30 MHz signals were also measured simultaneously. Out of a total of 107 flashes, 30 flashes had two strokes, 7 had three strokes and 3 flashes had four strokes. The arithmetic and geometric means of the interstroke intervals were found to be 116 and 70 ms, respectively. The arithmetic and geometric mean ratio between the peak electric field of the Subsequent Return Stroke (SRS) and the first Return Stroke (RS) were 0.48 and 0.36, respectively. Of the 40 positive multiple-stroke ground flashes, 5% have at least one SRS with field peak higher than the first RS. The percentage of SRS with field peaks greater than the first RS was 6%. In our best of our knowledge, this is the first time a large sample of positive return strokes in Sweden was analysed. It was found to be statistically more significant than the previous studies.

  1. Ab initio infrared and Raman spectra

    1983-06-01

    We discuss several ways in which molecular absorption and scattering spectra can be computed ab initio, from the fundamental constants of nature. These methods can be divided into two general categories. In the first, or sequential, type of approach, one first solves the electronic part of the Schrödinger equation in the Born-Oppenheimer approximation, mapping out the potential energy, dipole moment vector (for infrared absorption) and polarizability tensor (for Raman scattering) as functions of nuclear coordinates. Having completed the electronic part of the calculation, one then solves the nuclear part of the problem either classically or quantum mechanically. As an example of the sequential ab initio approach, the infrared and Raman rotational and vibrational-rotational spectral band contours for the water molecule are computed in the simplest rigid rotor, normal mode approximation. Quantum techniques are used to calculate the necessary potential energy, dipole moment, and polarizability information at the equilibrium geometry. A new quick, accurate, and easy to program classical technique involving no reference to Euler angles or special functions is developed to compute the infrared and Raman band contours for any rigid rotor, including asymmetric tops. A second, or simultaneous, type of ab initio approach is suggested for large systems, particularly those for which normal mode analysis is inappropriate, such as liquids, clusters, or floppy molecules. Then the curse of dimensionality prevents mapping out in advance the complete potential, dipole moment, and polarizability functions over the whole space of nuclear positions of all atoms, and a solution in which the electronic and nuclear parts of the Born-Oppenheimer approximation are simultaneously solved is needed. A quantum force classical trajectory (QFCT) molecular dynamic method, based on linear response theory, is described, in which the forces, dipole moment, and polarizability are computed quantum

  14. Collective rotation from ab initio theory

    NASA Astrophysics Data System (ADS)

    Caprio, Mark A.; Maris, Pieter; Vary, James P.

    2015-10-01

    The challenge of ab initio nuclear theory is to quantitatively predict the complex and highly-correlated behavior of the nuclear many-body system, starting from the underlying internucleon interactions. We may now seek to understand the wealth of nuclear collective phenomena through ab initio approaches. No-core configuration interaction (NCCI) calculations for p-shell nuclei give rise to rotational bands, as evidenced by rotational patterns for excitation energies, electromagnetic moments, and electromagnetic transitions. In this talk, the intrinsic structure of these bands is discussed, and the predicted rotational bands are compared to experiment. Supported by the US DOE under Award Nos.

    1983-01-01

    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.

    Vermiculite can interact with quaternary ammonium salts to form organmineral compounds in the ion-exchange adsorption of these salts from waste water. This paper investigates this interaction between vermiculite and Katamin AB, a commercial cationic surfactant consisting of an aqueous solution of alkylbenyldimethylammonium chloride homologs. It is shown that ion exchange and molecular sorption occur simultaneously during the interaction and that vermiculite is a highly effective adsorbent in process water purification.

    Signoracci, Angelo; Hagen, Gaute; Duguet, Thomas

    2014-09-01

    Coupled cluster (CC) theory has become a standard method in nuclear theory for realistic ab initio calculations of medium mass nuclei, but remains limited by its requirement of a Slater determinant reference state which reasonably approximates the nuclear system of interest. Extensions of the method, such as equation-of-motion CC, permit the calculation of nuclei with one or two nucleons added or removed from a doubly magic core, yet still only a few dozen nuclei are accessible with modern computational restrictions. In order to extend the applicability of ab initio methods to open-shell systems, the superfluid nature of nuclei must be taken into account. By utilizing Bogoliubov algebra and employing spontaneous symmetry breaking with respect to particle number conservation, superfluid systems can be treated by a single reference state. An ab initio theory to include correlations on top of a Bogoliubov reference state has been developed in the guise of standard CC theory. The formalism and first results of this Bogoliubov coupled cluster theory will be presented to demonstrate the applicability of the method.

    Vinod, Kateki; Gedde, Steven J

    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.

    2014-03-01

    Thermodynamical properties of titanium are of great interest for aerospace and aviation industries and many studies are done in order to understand its behaviour under pressure (P) and temperature (T) : phase transitions at low T, melting curve at high T and P. In this work we compute the first ab-initio melting curve of titanium. This one is obtained with the Abinit package using DFT, in the GGA approximation, and in the framework of the projector augmented wave method (PAW). At first, we perform ground state calculations and study the five allotropic phases of titanium. Two PAW atomic data are generated with two different cutoff radius. The larger one gives results near previews ab-initio calculations, whereas the smaller one gives results near all electron calculation. Using the second PAW atomic data and performing ab-initio molecular dynamic simulations, we then compute the melting curve of titanium with three different methods. Results show relevance of our calculations, but also discrepencies with experimental data.

    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

  2. Overview of the Scientific Balloon Activity in Sweden

    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

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

    Berglind, H

    1978-01-01

    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.

    2011-01-01

    SYNOPSIS Objective The present study examined mean level similarities and differences as well as correlations between mothers’ and fathers’ attributions regarding successes and failures in caregiving situations and progressive versus authoritarian attitudes. Design Interviews were conducted with both mothers and fathers in 77 Swedish families. Results Fathers reported higher adult-controlled failure and child-controlled failure attributions than did mothers; these differences remained significant after controlling for parents’ age, education, and possible social desirability bias. Significant positive correlations were found for mothers’ and fathers’ progressive attitudes, authoritarian attitudes, and modernity of attitudes after controlling for parents’ age, education, and possible social desirability bias. Conclusions We conclude that in Sweden fathers are more likely to attribute failures in caregiving situations both to themselves and to children than are mothers and that there is moderate concordance between fathers and mothers within the same family in progressive and authoritarian parenting attitudes.

  5. Fast Breeder Reactors in Sweden: Vision and Reality.

    PubMed

    Fjaestad, Maja

    2015-01-01

    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

    2014-09-01

    Promoting breastfeeding is important work for health-care personnel in the Swedish context. This promotion is multifaceted and demands the ongoing development of knowledge and competence among both health-care personnel and patients. The aim of the present study was to describe the nursing students' perspectives on breastfeeding in Sweden. Data were obtained in the form of written reflections from nursing students (n=65) and examined using manifest content analysis. The results show that the factors of importance in promoting successful breastfeeding are information about breastfeeding's benefits, traditions and cultural acceptance of the practice, and by government prohibition of infant formula. We conclude that knowledge about the benefits of breastfeeding needs to be prioritized continuously during education. PMID:25169002

    2012-09-01

    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.

  8. Pathological withdrawl of refugee children seeking asylum in Sweden.

    PubMed

    Hacking, Ian

    2010-12-01

    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

    2010-05-01

    'Scientific dishonesty' implies the fabrication, falsification or plagiarism in proposing, performing or reviewing research or in reporting research results. A questionnaire was given to postgraduate students at the medical faculties in Sweden who attended a course in research ethics during the academic year 2008/2009 and 58% answered (range 29%-100%). Less than one-third of the respondents wrote that they had heard about scientific dishonesty in the previous 12 months. Pressure, concerning in what order the author should be mentioned, was reported by about 1 in 10 students. We suggest that all departments conducting research should have a written policy about acceptable research behaviour and that all doctoral students should be informed of the content of this policy. Participants in the research groups concerned should also be required to analyse published articles about scientific dishonesty and critically discuss what could be done about unethical conduct.

  10. Recurrent education policy in Sweden: A moving target

    NASA Astrophysics Data System (ADS)

    Rubenson, Kjell

    1994-05-01

    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.

  11. Sexual assault, irresistible impulses, and forensic psychiatry in Sweden.

    PubMed

    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. PMID:24315847

    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 national Swedish cancer registry was used to analyse the age-specific time trends in breast cancer incidence in Sweden from 1970 to 1984. The analysis included both a calendar year and a birth cohort approach to estimate time trends in disease occurrence. According to the birth cohort approach there was a statistically significant increase in the incidence with an average annual increase of the incidence of 3.2% (P = 0.0114), 3.4% (P = 0.0002) and 2.2% (P = 0.0264) in the age groups 25-29, 30-34 and 35-39, respectively. Possible causes of the observed increasing incidence are discussed. PMID:2297482

    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

    2013-04-01

    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.

    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.

    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

    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.

    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.

    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.

    Environmental pollution with the nephrotoxic metal cadmium is considered a potential health risk for the general population. In 1976 it was reported that the cadmium concentration in human kidney cortex in Sweden had increased in parallel with increasing levels in soil and grain during the twentieth century. Since the cadmium concentration in farming lands is still increasing, the present study was undertaken to further elucidate whether the cadmium concentration in the kidney is still increasing. Kidney cortex biopsies were collected at 171 autopsies of victims to sudden and accidental death during 1995 and 1996, and the cadmium concentrations were determined and compared with previously published Swedish data obtained from forensic autopsies. The geometric mean cadmium concentration in kidney cortex in subjects 40 years of age and younger was about 40% of the concentration found in the 1970s, while the reduction was less pronounced among older people. The highest individual concentration of cadmium was 41.5 microg/g wet weight (ww). The geometric mean concentration was less than 14 microg/g ww at ages around 50 years of age, when the cadmium concentration in kidney cortex is highest, as compared with approximately 20 microg/g ww in the 1970s. There was also a reduction in cadmium concentrations among nonsmokers; thus, a decrease in tobacco smoking in Sweden during the last decades is not the only explanation for the reduction of cadmium in the kidney cortex. Other reasons for this reduction could be changes in dietary habits and reduced cadmium contamination from Swedish industries. Images Figure 1 PMID:9485480

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

    NASA Astrophysics Data System (ADS)

    Knotts, Greg

    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.

  8. Ab initio melting curve of osmium

    Burakovsky, L.; Burakovsky, N.; Preston, D. L.

    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.

  9. New challenges to medicare beneficiary access to mAbs

    PubMed Central

    Wilson, Andrew

    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

    Trawczyński, Dawid; Sosnowski, Janusz; Gawkowski, Piotr

    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.

    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.

    2015-02-01

    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.

    Ab initio calculations for neutron drops are of interest for insights into neutron-rich nuclei and neutron star matter, and for examining the neutron-only sector of nucleon-nucleon and 3-nucleon interactions. I present ab initio results calculated using the no-core shell model with 2- and 3-body chiral Hamiltonians for neutron drops up to 20 neutrons confined in a 10 MeV harmonic trap. I discuss ground state energies, internal energies, radii, and evidence for pairing. In addition, excitation energies can be used to investigate the spin-orbit splittings in the p-shell and sd -shell. Prior Green's Function Monte Carlo calculations using the Argonne v8' potential with added 3-nucleon forces serve as a comparison.

  1. Educational research in Sweden: Reform strategies and research policy

    NASA Astrophysics Data System (ADS)

    Marklund, Inger

    1981-06-01

    Educational R & D in Sweden is to a large extent policy-oriented. It has been an integrated part of the Swedish educational reform system and has brought about a dialogue between politicians, administrators and researchers. Several circumstances have contributed to the `Swedish model'. One is the system with government-appointed committees in which researchers often play an active part. Another is that the Swedish educational system is highly centralized, with the National Board of Education (NBE) as the central authority, responsible for primary, secondary and adult education. A third — and a crucial one — is that, since 1962, the NBE has had increasing funds for educational R & D at its disposal. These funds account for the main part of the economic resources for R & D, along with resources allocated to research appointments at research departments of universities. Educational R & D, conducted primarily within the NBE funds, has recently been evaluated by a government-appointed committee. In its evaluations of the impact of educational R & D, the committee distinguished between the effects of R & D and the effect correlates. It concluded that the impact of R & D is more indirect than direct, more long-term than immediate. The effects are also more easily recognized at levels above the actual school situation. This finding could be interpreted as a consequence of the policy-orientation of educational R & D, which at the same time shows the difficulties in reaching the `school level' with research and development results. There are two general trends in Sweden, which will influence both research planning and research use. First, there is a trend towards the decentralization of decision-making and responsibility for the educational system. Secondly, there is a trend towards the `sectionalization' of the R & D system as a whole. This sectionalization will mean that research will to a great extent be planned to meet needs from different parts of society — labour

    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

    In December 2015, an asylum seeker originating from Afghanistan was diagnosed with respiratory diphtheria in Finland. He arrived in Finland from Sweden where he had already been clinically suspected and tested for diphtheria. Corynebacterium diphtheriae was confirmed in Sweden and shown to be genotypically and phenotypically toxigenic. The event highlights the importance of early case detection, rapid communication within the country and internationally as well as preparedness plans of diphtheria antitoxin availability.

    Although other epidemics declined due to improved hygiene and sanitation, legislation, and vaccination, polio epidemics appeared in Sweden in 1881 and at the turn of the 20th century the disease became and annual feature in the Swedish epidemiological pattern. Due to the vaccination starting in 1957 epidemics ceased to exist in Sweden around 1965. This article deals with the history polio epidemics in Sweden, 1880-1965 and gives a brief description of: the demographical influence of polio, how did the medical authorities investigate and try to combat it, and the different comprehensions of how polio affected its victims.A study of polio incidence in Sweden at the national level during 1905-1962 reveals that the disease caused major epidemics in 1911-1913 and 1953. At the beginning of the 20th century polio primarily attacked children up to 10 years of age, and at the end of the period victims were represented in all age groups, but mainly in the ages 20-39. Due to its enigmatic appearance, polio was not considered as an epidemic infectious disease during the 19th century. Sweden's early epidemics enabled Swedish medical science to act and together with American research institutes it acquired a leading role in international medical research on the disease. In the 1955 Jonas Salk produced the first successful vaccine against polio but also Sweden developed its own vaccine, different in choice of methods and materials from the widely used Salk-vaccine.

    Objective: European Union travelers' allowances for alcohol import to Denmark, Sweden, and Finland were abolished in 2004. In addition, excise taxes on alcohol were lowered in 2003 and 2005 in Denmark, and in 2004 in Finland. Using northern Sweden as a control site, this study examines whether levels of reported alcohol problems have changed in Denmark, Finland, and southern Sweden as a consequence of these policy changes. Method: Annual cross-sectional surveys were conducted in Denmark, Finland, and Sweden from 2003 to 2006. Five dependency items and seven extrinsic alcohol-related problems were examined. Changes were analyzed within each country/region with logistic regressions and tested for short- and long-term changes. Differential change was also tested between each country and the control site, northern Sweden. Results: Prevalence of alcohol problems decreased over the study period. Only in selected subgroups did problems increase. This mainly occurred in the samples for northern Sweden and Finland, and mostly among older age groups and men. In relation to the control site, however, no increases in problem prevalence were found. Conclusions: Our findings on a decline in reported alcohol problems largely agree with published reports on alcohol consumption over the same period in the study countries. They do not agree, however, with findings on changes in health and social statistics in Finland and Denmark, where some significant increases in alcohol-related harm have been found. PMID:20105411

    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. PMID:8800805

    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.

    Objective The objectives of this study were to (1) analyze the prevalence of diabetes, prediabetes, and antidiabetic medication in patients with psychosis compared with control subjects and (2) determine what factors in patients with psychosis were associated with antidiabetic medication. Method We studied 977 patients with psychosis recruited from outpatient clinics in Stockholm County, Sweden, and they were compared with 3908 non-psychotic control subjects for fasting plasma glucose levels; prevalence of diabetes, prediabetes, antidiabetic treatment, and tobacco use; and blood pressure, weight, height, and waist circumference. Group differences were evaluated with analysis of variance and χ2 test, and factors associated with antidiabetic treatment were evaluated with logistic regression. Results Diabetes was observed in 94 (10%) patients with psychosis, 2.7 times the prevalence observed in control subjects. Among patients with psychosis, 87 (10%) had prediabetes (fasting glucose, 6.1–6.9 mmol/L) compared with 149 (3.8%) control subjects. Most patients with psychosis (77%) who had prediabetes fulfilled criteria for metabolic syndrome. In patients with psychosis, both lipid-lowering medication and fasting glucose were significantly associated with antidiabetic treatment. There was no significant relation between antidiabetic treatment and lifestyle factors such as smoking or degree of psychiatric illness. Conclusions The high prevalence of impaired fasting glucose and metabolic syndrome in patients with psychosis warrants further clinical research in preventing or delaying the onset of diabetes in these patients by pharmacotherapy and/or lifestyle intervention.

    2015-01-01

    Background. Sepsis is a serious and common condition with high mortality and morbidity. The public awareness, knowledge, and perception of sepsis in Sweden are unknown. Methods. A survey was performed using an online interview distributed to adults, aged 18–74, between March 6 and 9, 2015. Results. A total of 1001 people responded to the survey. Twenty-one percent of participants had heard of sepsis, whereas more than 86% had heard of each of the other conditions listed; for example, stroke (95%), chronic obstructive pulmonary disease (COPD) (95%), and leukemia (92%). Of those who had heard of sepsis, 93% responded that it is an infection or blood poisoning in an open question. The respondents who had heard of each disease estimated its mortality. For sepsis, the mortality was estimated at an average of 30%, which was at the same level as estimated mortalities for prostate and breast cancer but lower than for stroke, COPD, and leukemia. Conclusions. The awareness and knowledge of sepsis is low. The mortality for sepsis is not as overestimated as for many other diseases. The lack of awareness of sepsis might be a target to improve the outcome for sepsis patients by reducing the prehospital delay and hence enable early interventions. An increased general awareness might also raise interest for funding for research in this area and for its priority in healthcare support. PMID:26634220

    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

    The Swedish Meteorological and Hydrological Institute (SMHI) maintains a permanent river gauging network for national hydrological monitoring which includes 263 gauging stations in Sweden. At all these stations, water levels are measured continuously, and discharges are computed through rating curves. The network represents a wide range of environmental settings, different gauging measurement types and gauging frequencies. Gauging frequencies are typically low compared with river gauges in more research-oriented settings, and thus uncertainties in discharges, particularly extremes, can be large. On the other hand, the gauging stations have often been in use for very long, with the oldest measurements dating back to 1900, and at least partly exhibit very stable conditions. Here, we show the variation in gauging stability in the SMHI's gauging network in order to try to identify more error-prone conditions. We investigate how the current, largely subjective, way of updating rating curves influences discharge estimates, and discuss ways forward towards a more objective evaluation of both discharge uncertainty and rating curve updating procedures.

    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.

    For forty years, until 1955, spirits were rationed in Sweden under a system of individual control. Local "System companies" had a monopoly on the retail trade in spirits and wine. Private profits on alcohol were also eliminated in the restaurants and the wholesale trade. Legislation was based on the proposals put forward by the physician Ivan Bratt (1878-1956), who presented his ideas in 1909 as an alternative to prohibition. Bratt had the support of leading personalities in Swedish medicine, newspapers and politics, and he also enlisted the support of some of the leaders of the powerful temperance movement. In 1922, Swedes voted against prohibition in a referendum by 51% to 49%. The Bratt system substantially reduced alcohol abuse. When it was abolished, drunkenness in the streets doubled. By 1960, when high taxes had replaced rationing as the policy for controlling the consumption of alcohol, delirium tremens had increased since the Bratt period from 160 cases a year to 700 cases a year.

    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

    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 1994 International Conference on Population and Development (ICPD), the Fourth World Conference on Women, and ICPD+5 are but markers along a more long-term path and process of cooperation and dialogue between the world's governments and civil society organizations. Some groups are involved in implementing action, while others focus upon advocacy or act as watchdogs and pathfinders. Civil society organizations need space and financial resources to work upon their issues. In some areas, the ICPD program of action has not achieved what was expected. In particular, almost all countries have considerable work to do on gender equality, the needs of young people, the HIV/AIDS pandemic, and maternal mortality. These issues are discussed. More resources must be allocated to the social services in order to achieve the goals of the Cairo program of action. To that end, the government of Sweden is planning to increase its allocations for development cooperation over the next few years, moving upward from the 0.7 level adopted by the UN. PMID:12322191

    Although the Social Democratic Party lost its long control of Parliament, Sweden is a country with a strong egalitarian philosophy which transcends party politics, and it is felt that the loss of the election had virtually no affect on policy toward women or other aspects of social policy. A review of the Swedish political situation, including political parties; election issues; aftermath of the election; and labor force participation precedes consideration of developments in the economic status of women, 1976-1978. Factors considered include Labour Market Board equality measures; parenthood insurance; work hours; the Committee on Equality Between Men and Women; proposed legislation on equality; private agreements between employers and trade unions on family policy; and womens' participation. It is concluded that the new government has merely continued the equality programs of the previous government, with the only meaningful contribution of the new Equality Committee to draft legislation prohibiting discrimination. The law on equality is a vital issue for the Liberal Party and they will have to persuade the Social Democrats that its enactment will provide the basis of an egalitarian society. PMID:12309568

    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.

    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.

    We assess the concept of alchemical transformations for predicting how a further and not-tested change in composition would change materials properties. This might help to guide ab initio calculations through multidimensional property-composition spaces. Equilibrium volumes, bulk moduli, and relative lattice stability of fcc and bcc 4d transition metals Zr, Nb, Mo, Tc, Ru, Rh, Pd, and Ag are calculated using density functional theory. Alchemical derivatives predict qualitative trends in lattice stability while equilibrium volumes and bulk moduli are predicted with less than 9% and 28% deviation, respectively. Predicted changes in equilibrium volume and bulk moduli for binary and ternary mixtures of Rh-Pd-Ag are in qualitative agreement even for predicted bulk modulus changes as large as +100% or -50%. Based on these results, it is suggested that alchemical transformations could be meaningful for enhanced sampling in the context of virtual high-throughput materials screening projects.

    More than 99% of the mass of the visible universe is made up of protons and neutrons. Both particles are much heavier than their quark and gluon constituents, and the Standard Model of particle physics should explain this difference. We present a full ab initio calculation of the masses of protons, neutrons, and other light hadrons, using lattice quantum chromodynamics. Pion masses down to 190 mega-electron volts are used to extrapolate to the physical point, with lattice sizes of approximately four times the inverse pion mass. Three lattice spacings are used for a continuum extrapolation. Our results completely agree with experimental observations and represent a quantitative confirmation of this aspect of the Standard Model with fully controlled uncertainties. PMID:19023076

    Chemical understanding is driven by the experimental discovery of new compounds and reactivity, and is supported by theory and computation that provides detailed physical insight. 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 frommore » primitive compounds proposed to exist on the early Earth, providing new insight into the classic Urey-Miller experiment. Ultimately, 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.« less

    Ab initio molar volumes are calculated and used to derive radii for ions and neutral molecules using a spatially diffuse model of the electron distribution with Gaussian spread. The Gaussian radii obtained can be used for computation of nonelectrostatic ion-ion dispersion forces that underlie Hofmeister specific ion effects. Equivalent hard-sphere radii are also derived, and these are in reasonable agreement with crystalline ionic radii. The Born electrostatic self-energy is derived for a Gaussian model of the electronic charge distribution. It is shown that the ionic volumes used in electrostatic calculations of strongly hydrated cosmotropic ions ought best to include the first hydration shell. Ionic volumes for weakly hydrated chaotropic metal cations should exclude electron overlap (in electrostatic calculations). Spherical radii are calculated as well as nonisotropic ellipsoidal radii for nonspherical ions, via their nonisotropic static polarizability tensors. PMID:19140766

    Traditional approaches for modeling chemical reaction networks such as those involved in combustion have focused on identifying individual reactions and using theoretical approaches to explore the underlying mechanisms. Recent advances involving graphical processing units (GPUs), commodity products developed for the videogaming industry, have made it possible to consider a distinct approach wherein one attempts to discover chemical reactions and mechanisms. We provide a brief summary of these developments and then discuss the concept behind the ``ab initio nanoreactor'' which explores the space of possible chemical reactions and molecular species for a given stoichiometry. The nanoreactor concept is exemplified with an example to the Urey-Miller reaction network which has been previously advanced as a potential model for prebiotic chemistry. We briefly discuss some of the future directions envisioned for the development of this nanoreactor concept.

    Chemical understanding is driven by the experimental discovery of new compounds and reactivity, and is supported by theory and computation that provides detailed physical insight. 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

    We assess the concept of alchemical transformations for predicting how a further and not-tested change in composition would change materials properties. This might help to guide ab initio calculations through multidimensional property-composition spaces. Equilibrium volumes, bulk moduli, and relative lattice stability of fcc and bcc 4d transition metals Zr, Nb, Mo, Tc, Ru, Rh, Pd, and Ag are calculated using density functional theory. Alchemical derivatives predict qualitative trends in lattice stability while equilibrium volumes and bulk moduli are predicted with less than 9% and 28% deviation, respectively. Predicted changes in equilibrium volume and bulk moduli for binary and ternary mixtures of Rh-Pd-Ag are in qualitative agreement even for predicted bulk modulus changes as large as +100% or -50%. Based on these results, it is suggested that alchemical transformations could be meaningful for enhanced sampling in the context of virtual high-throughput materials screening projects.

    2014-01-01

    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.

    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 (4He), 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

    Laser sclerostomy ab externo with flashlamp excited mid-IR laser systems emitting in the 2-3 micrometer spectral range is in phase II clinical trials. Although acutely high success rates were achieved, the restenosis rate after several months is about 40%. Laser pulses of several hundreds of microseconds, known to induce thermo-mechanical explosive evaporation were used for this procedure. We investigated the ablation dynamics in tissue and the cavitation bubble dynamics in water by means of an Er:YAG laser system to estimate the extent of mechanical damage zones in the sclera and in the anterior chamber, which may contribute to the clinical failure. We found substantial mechanical tissue deformation during the ablation process caused by the cavitation effects. Stress waves up to several bar generated by explosive evaporization were measured. The fast mechanical stretching and collapsing of the scleral tissue induced by cavitation resulted in tissue dissection as could be proved by flash photography and histology. The observed high restenosis might be a result of a subsequent enhanced wound healing process. Early fistula occlusions due to iris adherences, observed in about 20% of the clinical cases may be attributed to intraocular trauma induced by vapor bubble expansion through the anterior chamber after scleral perforation. An automatic feedback system minimizing adverse effects by steering and terminating the laser process during scleral fistulization is demonstrated. Moreover, a new approach in laser sclerostomy ab externo is presented using a cw-IR laser diode system emitting at the 1.94 micrometer mid-IR water absorption peak. This system was used in vitro and showed smaller damage zones compared to the pulsed laser radiation.

    Background Abnormal lung function is commonly identified by comparing observed spirometric values to corresponding reference values. It is recommended that such reference values for spirometry are evaluated and updated frequently. The aim of this study was to estimate new reference values for Swedish adults by fitting a multivariable regression model to a healthy non-smoking general population sample from northern Sweden. Further aims were to evaluate the external validity of the obtained reference values on a contemporary sample from south-western Sweden, and to compare them to the Global Lung Function Initiative (GLI) reference values. Method Sex-specific multivariable linear regression models were fitted to the spirometric data of n=501 healthy non-smoking adults aged 22–91 years, with age and height as predictors. The models were extended to allow the scatter around the outcome variable to depend on age, and age-dependent spline functions were incorporated into the models to provide a smooth fit over the entire age range. Mean values and lower limits of normal, defined as the lower 5th percentiles, were derived. Result This modelling approach resulted in unbiased estimates of the spirometric outcomes, and the obtained estimates were appropriate not only for the northern Sweden sample but also for the south-western Sweden sample. On average, the GLI reference values for forced expiratory volume in one second (FEV1) and, in particular, forced expiratory vital capacity (FVC) were lower than both the observed values and the new reference values, but higher for the FEV1/FVC ratio. Conclusion The evaluation based on the sample of healthy non-smokers from northern Sweden show that the Obstructive Lung Disease in Northern Sweden reference values are valid. Furthermore, the evaluation based on the south-western Sweden sample indicates a high external validity. The comparison with GLI brought further evidence to the consensus that, when available, appropriate local

    It is of interest to know the spatial variation and the amount of (137)Cs e.g. in case of an accident with a radioactive discharge. In this study, the spatial distribution of the quarterly (137)Cs deposition over Sweden due to nuclear weapons fallout (NWF) during the period 1962-1966 was determined by relating the measured deposition density at a reference site to the amount of precipitation. Measured quarterly values of (137)Cs deposition density per unit precipitation at three reference sites and quarterly precipitation at 62 weather stations distributed over Sweden were used in the calculations. The reference sites were assumed to represent areas with different quarterly mean precipitation. The extent of these areas was determined from the distribution of the mean measured precipitation between 1961 and 1990 and varied according to seasonal variations in the mean precipitation pattern. Deposition maps were created by interpolation within a geographical information system (GIS). Both integrated (total) and cumulative (decay corrected) deposition densities were calculated. The lowest levels of NWF (137)Cs deposition density were noted in north-eastern and eastern parts of Sweden and the highest levels in the western parts of Sweden. Furthermore the deposition density of (137)Cs, resulting from the Chernobyl accident was determined for an area in western Sweden based on precipitation data. The highest levels of Chernobyl (137)Cs in western Sweden were found in the western parts of the area along the coast and the lowest in the east. The sum of the deposition densities from NWF and Chernobyl in western Sweden was then compared to the total activity measured in soil samples at 27 locations. Comparisons between the predicted values of this study show a good agreement with measured values and other studies. PMID:16647743

    Objective To study the prevalence of tobacco use among teenagers, to evaluate a tobacco prevention programme and to study factors related to participation in the prevention programme. Design and setting Population-based prospective cohort study. Method Within the Obstructive Lung disease in Northern Sweden (OLIN) studies, a cohort study about asthma in schoolchildren started in 2006. All children aged 7–8 years in three municipalities were invited to a questionnaire survey and 2585 (96%) participated. The cohort was followed up at age 11–12 years (n=2612, 95% of invited) and 14–15 years (n=2345, 88% of invited). In 2010, some of the children in the OLIN cohort (n=447) were invited to a local tobacco prevention programme and 224 (50%) chose to participate. Results At the age of 14–15 years, the prevalence of daily smoking was 3.5%. Factors related to smoking were female sex, having a smoking mother, participation in sports and lower parental socioeconomic status (SES). The prevalence of using snus was 3.3% and risk factors were male sex, having a smoking mother, having a snus-using father and non-participation in the prevention programme. In the prevention programme, the prevalence of tobacco use was significantly lower among the participants compared with the controls in the cohort. Factors related to non-participation were male sex, having a smoking mother, lower parental SES and participation in sports. Conclusions The prevalence of tobacco use was lower among the participants in the tobacco prevention programme compared with the non-participants as well as with the controls in the cohort. However, the observed benefit of the intervention may be overestimated as participation was biased by selection. PMID:25976765

  9. Environmental issues in Sweden 1973 1989: Science and policy

    1991-09-01

    The aim of this study is to analyze the environmental agenda in Sweden during the last two decades. A content analysis was made of all articles in a Swedish journal, Miljö-Aktuellt. Further, to elucidate the evolutionary process of problem formulation and reformulation, two cases were investigated, dealing with the impact of plant nutrients and mercury on surface water quality. The transport of heavy metals is an essential component of the ecological process and problem of acidification, and similarly, plant nutrients are part of the concept of eutrophication. Two concepts, the research cycle and the policy cycle, are tentatively applied to the conceptualizations of acidification and eutrophication. Additional data for the latter part of the study is supplied from parliamentary motions during 1973 1989. The substance/media focus of the 1970s was connected to a point-source abatement strategy, which mainly aimed at removing negative effects at a local level. The development of a national preventive strategy is traced in problem formulations related to “processes” going on in the technosphere: wastes, noise, energy production, traffic, and toxic substances. This period lasted from the mid-1970s to the mid-1980s, and the need for improved resource management as a means to control environmental problems has been a generally accepted idea. However, this does not mean that measures actually taken are sufficient in a material balance perspective. Further, in the 1980s there was a strong emphasis upon processes in the ecosphere. This focus also implies source-related policies. To a certain extent, the remedies are within the scope of national capabilities, but the international dimension is becoming increasingly important. Scientific proofs of resource and environment degradation are essential to induce political action and to stimulate international cooperation. From this study, however, it is not possible to assess the existence of any particular policy

  10. Organic matter loss from cultivated peat soils in Sweden

    NASA Astrophysics Data System (ADS)

    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.

    2003-01-01

    The objective of this study conducted in 75 herds was to investigate the presence and significance of Criptosporidium parvum and Giardia intestinalis in Swedish dairy calves in comparison with rotavirus, coronavirus and Escherichia coli K99+. The farmers were asked to collect faecal samples from each heifer calf that had diarrhoea between birth and 90 days of age, and also from a healthy calf of the same age. In total, 270 samples were collected and analysed. C. parvum, either alone or together with G. intestinalis and/or rotavirus, was detected in 16 (11%) and 6 (5%) of the samples from diarrhoeic and healthy calves, respectively. Even though a higher proportion of diarrhoeic calves shed C. parvum, the difference between the groups was not statistically significant (p = 0.067), possibly due to the low number of positive samples. G. intestinalis was found in 42 (29%) of the diarrhoea samples and in 29 (23%) of the samples from healthy calves. Rotavirus and coronavirus were demonstrated in 24% and 3% of the diarrhoea samples, respectively, whereas E. coli K99+ was only found in samples from 2 healthy calves. C. parvum and G. intestinalis were found in samples from calves 7 to 84 days of age and during all seasons. The results confirm that C. parvum is present in Swedish dairy herds and might have clinical significance. G. intestinalis was the most common agent found but the importance of this parasite remains unclear. Both parasites have suggested zoonotic potential and thus warrant further attention. In addition, rotavirus is a major pathogen in neonatal enteritis in Sweden, whereas coronavirus and E. coli K99+ seem to be of less importance. PMID:15074627

    2011-01-01

    In Sweden, as in many other European countries, traffic noise is an important environmental health issue. At present, almost two million people are exposed to average noise levels exceeding the outdoor national guideline value (55 dB(A)). Despite efforts to reduce the noise burden, noise-related health effects, such as annoyance and sleep disturbances, are increasing. The scientific interest regarding more serious health effects related to the cardiovascular system is growing, and several experimental and epidemiological studies have been performed or are ongoing. Most of the studies on cardiovascular outcomes have been related to noise from road or aircraft traffic. Few studies have included railway noise. The outcomes under study include morning saliva cortisol, treatment for hypertension, self-reported hypertension, and myocardial infarction. The Swedish studies on road traffic noise support the hypothesis of an association between long-term noise exposure and cardiovascular disease. However, the magnitude of effect varies between the studies and has been shown to depend on factors such as sex, number of years at residence, and noise annoyance. Two national studies have been performed on the cardiovascular effects of aircraft noise exposure. The first one, a cross-sectional study assessing self-reported hypertension, has shown a 30% risk increase per 5 dB(A) noise increase. The second one, which to our knowledge is the first longitudinal study assessing the cumulative incidence of hypertension, found a relative risk (RR) of 1.10 (95% CI 1.01 - 1.19) per 5 dB(A) noise increase. No associations have been found between railway noise and cardiovascular diseases. The findings regarding noise-related health effects and their economic consequences should be taken into account in future noise abatement policies and community planning. PMID:21537104

    1998-03-30

    The Alvar engine is an invention by Mr. Alvar Gustafsson of Skarblacka, Sweden. It is a four stroke spark ignition internal combustion engine, having variable compression ratio and variable displacements. The compression ratio can be varied by means of small secondary cylinders and pistons which are communicating with the main combustion chambers. The secondary pistons can be phase shifted with respect to the main pistons. The engine is suitable for multi-fuel operation. Invention rights are held by Alvar Engine AB of Sweden, a company created to handle the development of the Alvar Engine. A project was conceived wherein an optimised experimental engine would be built and tested to verify the advantages claimed for the Alvar engine and also to reveal possible drawbacks, if any. Alvar Engine AB appointed Gunnar Lundholm, professor of Combustion Engines at Lund University, Lund, Sweden as principal investigator. The project could be seen as having three parts: (1) Optimisation of the engine combustion chamber geometry; (2) Design and manufacturing of the necessary engine parts; and (3) Testing of the engine in an engine laboratory NUTEK, The Swedish Board for Industrial and Technical Development granted Gunnar Lundholm, SEK 50000 (about $6700) to travel to the US to evaluate potential research and development facilities which seemed able to perform the different project tasks.

    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

    A hundred years ago the prevalence of tuberculosis (TB) in Sweden was one of the highest in the world. In this study we conducted a population-based search for distinct strains of Mycobacterium tuberculosis complex isolated from patients born in Sweden before 1945. Many of these isolates represent the M. tuberculosis complex population that fueled the TB epidemic in Sweden during the first half of the 20th century. Methods Genetic relationships between strains that caused the epidemic and present day strains were studied by spoligotyping and restriction fragment length polymorphism. Results The majority of the isolates from the elderly population were evolutionary recent Principal Genetic Group (PGG)2/3 strains (363/409 or 88.8%), and only a low proportion were ancient PGG1 strains (24/409 or 5.9%). Twenty-two were undefined. The isolates demonstrated a population where the Euro-American superlineage dominated; in particular with Haarlem (41.1%) and T (37.7%) spoligotypes and only 21.2% belonged to other spoligotype families. Isolates from the elderly population clustered much less frequently than did isolates from a young control group population. Conclusions A closely knit pool of PGG2/3 strains restricted to Sweden and its immediate neighbours appears to have played a role in the epidemic, while PGG1 strains are usually linked to migrants in todaýs Sweden. Further studies of these outbreak strains may give indications of why the epidemic waned. PMID:23056484

    Recommodification, the withdrawal of social welfare, has been going on for some decades in both Sweden and England. Recommodification disproportionately affects the unemployed because of their weak market position. We investigated the impact recommodification has had on health inequalities between the employed and unemployed in Sweden and England. Using national surveys, odds ratios for the likelihood of reporting less than good health between the employed and unemployed were computed annually between 1991 and 2011. The correlation between these odds ratios and net replacement rates was then examined. Health inequalities between the employed and unemployed were greater in 2011 than in 1991 in both countries. Sweden began with smaller health inequalities, but by 2011, they were in line with those in England. Sweden experienced more recommodification than England during this period, although it started from a much less commodified position. Correspondingly, correlation between unemployment benefit generosity and health inequalities was stronger in Sweden than in England. Recommodification is linked to ill health among the unemployed and to the health gap between the employed and unemployed. We propose that further recommodification will be associated with increased health inequalities between the employed and unemployed. PMID:27000134

  20. 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

    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.

    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 H2 and O2. 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.

    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.

    2016-08-01

    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.

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

    Semadeni-Davies, Annette

    2006-01-01

    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

    Background: High midlife and late-life adiposity may increase risk for dementia. Late-life decrease in body mass index (BMI) or body weight within several years of a dementia diagnosis has also been reported. Differences in study designs and analyses may provide different pictures of this relationship. Methods: Thirty-two years of longitudinal body weight, BMI, waist circumference, and waist-to-hip ratio (WHR) data, from the Prospective Population Study of Women in Sweden, were related to dementia. A representative sample of 1,462 nondemented women was followed from 1968 at ages 38-60 years, and subsequently in 1974, 1980, 1992, and 2000, using neuropsychiatric, anthropometric, clinical, and other measurements. Cox proportional hazards regression models estimated incident dementia risk by baseline factors. Logistic regression models including measures at each examination were related to dementia among surviving participants 32 years later. Results: While Cox models showed no association between baseline anthropometric factors and dementia risk, logistic models showed that a midlife WHR greater than 0.80 increased risk for dementia approximately twofold (odds ratio 2.22, 95% confidence interval 1.00-4.94, p = 0.049) among surviving participants. Evidence for reverse causality was observed for body weight, BMI, and waist circumference in years preceding dementia diagnosis. Conclusions: Among survivors to age 70, high midlife waist-to-hip ratio may increase odds of dementia. Traditional Cox models do not evidence this relationship. Changing anthropometric parameters in years preceding dementia onset indicate the dynamic nature of this seemingly simple relationship. There are midlife and late-life implications for dementia prevention, and analytical considerations related to identifying risk factors for dementia.

    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.

    Slowly-eroding, blockfield-mantled, non-glacial surface remnants may serve as markers against which to determine Quaternary glacial erosion volumes in high latitude mountain settings. To investigate this potential utility of these surfaces, chemical weathering, erosion rates, and origins of mountain blockfields are investigated in northern Sweden. This is done, firstly, by assessing the intensity of regolith chemical weathering along altitudinal transects descending from three blockfield-mantled summits. Clay/silt ratios, secondary mineral assemblages determined through X-ray diffraction, and the presence of chemically weathered grains visible on scanning electron microscopy, in fine matrix samples collected from pits excavated along the transects are each used for this purpose. Secondly, erosion rates and total surface histories of two of the summits are inferred from concentrations of in situ-produced cosmogenic 10Be and 26Al in quartz at the blockfield surface. An interpretative model is adopted that includes temporal variations in nuclide production rates through surface burial by glacial ice and glacial isostasy-induced elevation changes of the blockfield surfaces. Together, our data indicate that these blockfields are not derived from remnants of intensely weathered Neogene weathering profiles, as is commonly considered. Evidence for this interpretation includes minor chemical weathering in each of the three examined blockfields, despite some differences according to slope position. In addition, average erosion rates of ∼16.2 mm ka-1 and ∼6.7 mm ka-1, calculated for two blockfield-mantled summits, are low but of sufficient magnitude to remove present blockfield mantles, of up to a few meters in thickness, within a late-Quaternary timeframe. Hence, blockfield mantles appear to be replenished by regolith formation through, primarily physical, weathering processes that have operated during the Quaternary. Erosion rates remain low enough, however, for

    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

    2014-01-01

    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.

    Since 1986, 68% of the Listeria monocytogenes isolates from human cases of invasive listeriosis in Sweden are available for retrospective studies. The aim of the present study was to characterize 601 human invasive isolates of L. monocytogenes in Sweden from 1986 to 2007 by using serotyping and pulsed-field gel electrophoresis. Since 1996, serovar 4b was permanently reduced to the second or third most common serovar in human cases in Sweden. During the latter period, 2000-2007, only 13% belonged to serovar 4b and 71% to 1/2a. The dendrogram, based on pulsovars, reveals two clusters with different serovars. Cluster 1 exhibits serovars 4b and 1/2b, whereas cluster 2 consists of serovar 1/2a. Serovar 1/2a seems to be more heterogeneous than serovar 4b. PMID:18847381

    In Europe, the number of reported sporadic human cases of Salmonella Livingstone infection is low, and outbreaks are rare. We report the largest S. Livingstone outbreak described in the literature having an identified source of infection. In February 2001, an increased incidence of infection caused by S. Livingstone was observed in Norway and Sweden. By July 2001, 44 cases were notified in Norway and 16 in Sweden. The median age was 63 years, and 40 were women. There were three deaths, and 22 patients were hospitalized. Based on standardized questionnaires and retrospective studies of S. Livingstone strains in Norway and Sweden, food items with egg powder were suspected, and S. Livingstone was subsequently recovered from a processed fish product at the retail level. Analysis by pulsed-field gel electrophoresis documented that isolates from the fish product belonged to the same clone as the outbreak strain. PMID:15473152

    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.

    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. PMID:24682217

    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.

    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.

    Leptospirosis is an emerging zoonosis of global concern; however, its contemporary occurrence in Sweden, a European country partly located north of the Arctic Circle, is poorly known. Four out of 30 brown rats, captured within urban districts in Sweden, were found to be positive for antibodies to Leptospira interrogans serovar Icterohaemorrhagiae. This serovar causes Weil's disease in humans, a severe infection with jaundice, renal failure, and hemorrhage. Our study is the first finding of this highly pathogenic serovar in Swedish rats since the 1930s. PMID:26579782

    Present patterns of food consumption in Sweden include a substantial amount of imported vegetables as well as meat. Such a diet may be questioned for sustainability because of its dependence on, for example, inputs of energy emissions of greenhouse gases during the production, transportation and storage of some selected food consumed in Sweden during 1993 are quantified here. Contributors to the selected impact category are energy related emissions, leakage of refrigerants, and emissions of nitrous oxides from farm land. Total emissions are calculated in grams of CO{sub 2} equivalents per capita and per kg product.

    The Czech Republic, England, France, Germany and Sweden differ culturally and economically, but they commonly exhibit general trends of decentralisation in the control of educational processes and outcomes. The present contribution looks at these five European countries as the venue for case studies in educational restructuring as well as evaluation, assessment and reporting. It shows that such trends have been most radical in the Czech Republic and Sweden, while England has centralised curriculum policy and France has devolved some decision-making to bodies at lower levels, but as representatives of the central state.

    Background and purpose Some patients have persistent symptoms after total hip arthroplsty (THA). We investigated whether the proportions of inferior clinical results after total hip arthroplasty—according to the 5 dimensions in the EQ-5D form, and pain and satisfaction according to a visual analog scale (VAS)—are the same in immigrants to Sweden as observed in those born in Sweden. Methods Records of total hip arthroplasties performed between 1992 and 2007 were retrieved from the Swedish Hip Arthroplasty Register (SHAR) and cross-matched with data from the National Board of Health and Welfare and also Statistics, Sweden. 18,791 operations (1,451 in immigrants, 7.7%) were eligible for analysis. Logistic and linear regression models including age, sex, diagnosis, type of fixation, comorbidity, surgical approach, marital status, and education level were analyzed. Outcomes were the 5 dimensions in EQ-5D, EQ-VAS, VAS pain, and VAS satisfaction. Preoperative data and data from 1 year postoperatively were studied. Results Preoperatively (and after inclusion of covariates in the regression models), all immigrant groups had more negative interference concerning self-care. Immigrants from the Nordic countries outside Sweden and Europe tended to have more problems with their usual activities and patients from Europe and outside Europe more often reported problems with anxiety/depression. Patients born abroad showed an overall tendency to report more pain on the VAS than patients born in Sweden. After the operation, the immigrant groups reported more problems in all the EQ-5D dimensions. After adjustment for covariates including the preoperative baseline value, most of these differences remained except for pain/discomfort and—concerning immigrants from the Nordic countries—also anxiety/depression. After the operation, pain according to VAS had decreased substantially in all groups. The immigrant groups indicated more pain than those born in Sweden, both before and

    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.

    Post-glacial faults are well documented in northern Fennoscandia. They are pre-existing bedrock structures that were reactivated through a combination of isostatic and tectonic stresses following the retreat of the last Fennoscandian Ice Sheet. The locations and geometries of such features are important for evaluating seismic hazard. The current project utilizes LiDAR-derived imagery, which covers 80% of Sweden, to map linear scarps that cross cut glacial deposits or landforms. Through detailed manual interpretation of high-resolution imagery, previously unknown post-glacial fault scarps have been identified in central Sweden. Additionally, previously mapped scarps in northern Sweden have been refined or rejected. Despite full LiDAR coverage of southern Sweden, no post-glacial fault scarps were identified. The current dataset is available from the Geological Survey of Sweden, and will be kept up to date as new LiDAR coverage becomes available.

    The purpose of this series of studies was to evaluate the outcome of orthodontic care in Sweden from the professional's and the patient's perspective. In addition, a model was devised for the priority-planning of orthodontic care and for evaluating the different factors influencing the decision for orthodontic treatment. The results may be summarized as follows: Treatment Decision. Treatment desire, followed by treatment need and treatment benefit were the most important factors to consider when deciding whether or not treatment should be carried out. Regardless of the differences in resources and the structure of the free public care, a substantial proportion of the untreated 19-year-olds had malocclusions with treatment need, but they had no desire for treatment. Most of the 27-year-old individuals were satisfied with their earlier treatment decision, regardless of whether they had undergone orthodontic treatment. Dental professionals were considered to have had the greatest influence on this decision, which means that desire for treatment may be guided by the orthodontist. Individuals with malocclusions and treatment need--but who had refused proposed orthodontic treatment--were in general more discontented with their dental arrangement than other respondents, and a majority of them regretted their decision. Greater information to these individuals would have been desirable. Resources and Treatments Provided by General Practitioners or by Specialists. The sparsity of specialist resources resulted in either a greater restriction on the number necessary treatments being initiated or a greater proportion of the treatment being provided by general practitioners. In the 3 counties analysed, the treatment standard correlated well with the available resources: the greater the number of orthodontic specialists and ability to supervise the work of general practitioners and taking care of patients in need of specialist treatment, the higher the standard of treatment

    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

    Peaks in phosphorus concentrations are observed in connection to the spring flood in some, mainly unregulated, rivers in northern Sweden draining to the Baltic Sea. The elevated concentrations are only seen during a few days prior and following peak discharge in the rivers. This rapid event is often missed by the water quality monitoring programme with a standard monthly sampling frequency. As a consequence, calculated transport of phosphorus, both from interpolation of measurements and from simulations by models calibrated using observed time series may therefore be significantly lower than the actual transport. Possible explanations of this phenomenon were investigated using two numerical water quality models, the HYPE and HBV-NP models. The hypothesis was that the observed peaks in phosphorus concentrations were due to either river bank erosion, flash-out of previously settled phosphorus-laden particles in rivers and/or elevated loading from land in connection to snowmelt in the lowland areas of the catchment. The modelling exercise was supported by high frequency (daily) measurements of phosphorus concentration during the spring flood of 2008 and 2009 in River Kalixälven and in River Umeälven. Results from the study indicate that different processes may be important in the studied catchments. The dynamics of the simulated phosphorus concentrations from the HBV-NP model, used for the Swedish reporting to HELCOM, greatly improved when a model function controlling sedimentation and resuspension processes in watercourses was activated. Regulated rivers in contrast to unregulated ones have relatively high sustained discharge throughout the winter period which hinders the sedimentation of particles. This could explain why mainly unregulated rivers experience elevated phosphorous concentrations during spring flood. Including bank erosion in the HBV-NP simulations increased simulated phosphorus transport to the right magnitude. Observations showed that the phenomenon

    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

    2015-07-01

    In the current investigation, ab initio calculations are performed to explore the influence of electric field on the mechanical properties of bilayer boron nitride with AB stacking order (AB-2LBN). To accomplish this, density functional theory (DFT) within the framework of generalized gradient approximation (GGA) is implemented. It is demonstrated that the electric field has significant effects on Young's modulus and Poisson's ratio of AB-2LBN when its magnitude is small. With increasing the magnitude of electric field, these effects diminish so that the mechanical properties with and without considering the electric field become approximately identical. Also, it is shown that the equilibrium strain energy decreases linearly by increasing the magnitude of applied electric field.

    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 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

    This article reviews case reports for 58 suspected impaired driving cases that were positive for the synthetic cannabinoids AB-CHMINACA or AB-PINACA. All cases were submitted to the Washington State Patrol Toxicology Laboratory in 2014 from either Washington State or State of Alaska law enforcement agencies. The population of drivers was predominantly male (95%), with a mean age of 28 years (range, 18-61 years). The range of blood concentrations was 0.6->10 ng/mL for AB-CHMINACA (N = 33) and 0.6-41.3 ng/mL for AB-PINACA (N = 25). Drug Recognition Expert exams were performed in 10 cases for each AB-CHMINACA and AB-PINACA. Horizontal gaze nystagmus was observed in 50 and 60% of the cases, respectively. Overall, several physiological indicators varied from those typically observed with marijuana use. The majority of these cases had very poor driving; subjects were involved in an accident, found passed out in a vehicle or were called in as a suspected impaired driver. Slurred speech, confusion, lack of coordination/dexterity and lethargy were commonly observed. PMID:26378139

    Lass, Jana; Odlind, Viveca; Irs, Alar; Lutsar, Irja

    2013-12-01

    Aims of the study were to compare the paediatric outpatient antibiotic use in two countries with low overall antibiotic consumption and antibacterial resistance levels - Sweden and Estonia - and to describe the adherence to Estonian treatment guideline. All prescriptions for systemic antibiotics for children less than 18 years during 2007 from the Swedish Prescribed Drug Register and Estonian Health Insurance Fund database were identified to conduct a descriptive drug utilisation study. The total paediatric antibiotic use was 616 and 353 per 1000 in Estonia and Sweden, respectively. The greatest between country differences occurred in the age group 2 to 6 years -Estonian children received 1184 and Swedish children 528 prescriptions per 1000. Extended spectrum penicillin amoxicillin (189 per 1000) or its combination with beta-lactamase inhibitor (81 per 1000) and a newer macrolide clarithromycin (127 per 1000) were prescribed most often in Estonia whereas narrow spectrum penicillin phenoxymethylpenicillin (169 per 1000) and older generation macrolide erythromycin (21 per 1000) predominated in Sweden. For acute bronchitis, 17 different antibiotics (most commonly clarithromycin) were prescribed in Estonia despite the guideline recommendation not to use antibiotics. The higher rate of antibiotic use especially of extended spectrum antibiotics in Estonia compared to Sweden emphasizes the need for national activities to promote appropriate use of antibiotics while treating children, even when the overall antibiotic consumption is low.

  13. Exposure and accumulation of cadmium in populations from Japan, the United States, and Sweden

    PubMed Central

    Kjellström, Tord

    1979-01-01

    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

  16. Residential mobility among foreign-born persons living in Sweden is associated with lower mortality

    PubMed Central

    Albin, Björn; Hjelm, Katarina; Ekberg, Jan; Elmståhl, Sölve

    2010-01-01

    There have been few longitudinal studies on the effect of within-country mobility on patterns of mortality in deceased foreign-born individuals. The results have varied; some studies have found that individuals who move around within the same country have better health status than those who do not change their place of residence. Other studies have shown that changing one’s place of residence leads to more self-reported health problems and diseases. Our aim was to analyze the pattern of mortality in deceased foreign-born persons living in Sweden during the years 1970–1999 in relation to distance mobility. Data from Statistics Sweden and the National Board of Health and Welfare was used, and the study population consisted of 281,412 foreign-born persons aged 16 years and over who were registered as living in Sweden in 1970. Distance mobility did not have a negative effect on health. Total mortality was lower (OR 0.71; 95% CI 0.69–0.73) in foreign-born persons in Sweden who had changed their county of residence during the period 1970–1990. Higher death rates were observed, after adjustment for age, in three ICD diagnosis groups “Injury and poisoning”, “External causes of injury and poisoning”, and “Diseases of the digestive system” among persons who had changed county of residence.

    PubMed Central

    Nilsson, M; Norberg, B; Hultdin, J; Sandstrom, H; Westman, G; Lokk, J

    2005-01-01

    Background: Sweden is the only country in which oral high dose vitamin B12 has gained widespread use in the treatment of deficiency states. Objective: The aim of the study was to describe prescribing patterns and sales statistics of vitamin B12 tablets and injections in Sweden 1990–2000. Design, setting, and sources: Official statistics of cobalamin prescriptions and sales were used. Results: The use of vitamin B12 increased in Sweden 1990–2000, mainly because of an increase in the use of oral high dose vitamin B12 therapy. The experience, in statistical terms a "total investigation", comprised 1 000 000 patient years for tablets and 750 000 patient years for injections. During 2000, 13% of residents aged 70 and over were treated with vitamin B12, two of three with the tablet preparation. Most patients in Sweden requiring vitamin B12 therapy have transferred from parenteral to oral high dose vitamin B12 since 1964, when the oral preparation was introduced. Conclusion: The findings suggest that many patients in other post-industrial societies may also be suitable for oral vitamin B12 treatment. PMID:15749797

  9. The AB Dor Moving Group: A Chemically Heterogeneous Kinematic Stream?

    NASA Astrophysics Data System (ADS)

    Barenfeld, Scott A.; Bubar, E. J.; Mamajek, E. E.; Young, P. A.

    2012-01-01

    The AB Dor Moving Group is the nearest kinematic group to the Sun. It consists of a "nucleus" of 10 comoving stars at distance 20 pc (Zuckerman et al. 2004), along with dozens of purported "stream" members spread out across the sky, with distances up to 140 pc away (Torres et al. 2008). We perform a kinematic and chemical analysis of a sample of 10 AB Dor "stream" members to test whether they constitute a physical stellar group. We use the NEMO Galactic kinematic code to investigate the orbits of the stream members, and perform a chemical abundance analysis using high resolution, high S/N spectra taken with the MIKE spectrograph on the Magellan Clay 6.5-m telescope. Using a chi-squared test with the measured abundances for 10 different elements (Fe, Na, Mg, Si, Al, Ca, Cr, Mn, Ni, and Ba), we find that only a few of the ten purported AB Dor stream members appear to constitute a statistically chemically homogeneous sample. Our orbit simulations show that some of the "stream" members were hundreds of pc from AB Dor 100 Myr ago, and hence were unlikely to have formed near the eponymous star. The lack of kinematic and chemical coherence among the stream sample suggests that the published lists of AB Dor moving group members are unlikely to represent the dispersed remnant of a single star formation episode. Our study does not rule out the physicality of the AB Dor "nucleus" identified by Zuckerman et al., which appears to be coeval with the Pleiades ( 120 Myr). We conclude that the AB Dor stream is dynamical in nature, likely containing stars from many different birth sites. This research was supported by NSF grant AST-1008908, an REU supplement, and funds from the School of Arts and Sciences at the University of Rochester.

  10. First identification of Echinococcus multilocularis in rodent intermediate hosts in Sweden

    Echinococcus multilocularis is a zoonotic tapeworm with a sylvatic lifecycle and an expanding range in Europe. Monitoring efforts following its first identification in 2011 in Sweden have focused on the parasite's definitive host, the red fox (Vulpes vulpes). However, identifying rodent intermediate hosts is important to recognize opportunities for parasite transmission. During 2013–2015, livers from a total of 1566 rodents from four regions in Sweden were examined for E. multilocularis metacestode lesions. Species identity of suspect parasite lesions was confirmed by PCR and sequencing. E. multilocularis positive lesions >6 mm in diameter were also examined histologically. One Microtus agrestis out of 187 (0.5%, 95%CI: 0–2.9%), 8/439 (1.8%, 95%CI: 0.8–3.6%) Arvicola amphibius, 0/655 (0%, 95%CI: 0–0.6%) Myodes glareolus, and 0/285 (0%, 95%CI: 0–1.3%) Apodemus spp. contained E. multilocularis metacestode lesions. Presence of protoscoleces was confirmed in the infected M. agrestis and in three of eight infected A. amphibius. Six of the nine positive rodents were captured from the same field. This is the first report of E. multilocularis in intermediate hosts in Sweden. The cluster of positive rodents in one field shows that local parasite prevalence can be high in Sweden despite overall low national prevalence in foxes (<0.1%). The presence of protoscoleces in infected M. agrestis and A. amphibius indicate these species can serve as competent intermediate hosts in Sweden. However, their relative importance for E. multilocularis transmission in the Swedish environment is not yet possible to assess. In contrast, the negative findings in all M. glareolus and Apodemus spp. suggest that these species are of no importance. PMID:27054089

    Aarestrup, F M; Rasmussen, S R; Artursson, K; Jensen, N E

    1998-08-28

    This study was conducted to determine the MIC values of historical and contemporary Streptoccocus suis (serotypes 2 and 7) from Denmark and S. suis (serotype 2) from Sweden. A total of 52 isolates originating from 1967 through 1981 and 156 isolates from 1992 through 1997 in Denmark and 13 isolates from Sweden were examined for their MICs against 20 different antimicrobial agents. Most antimicrobials were active against most isolates. A frequent occurrence of resistance to sulphamethoxazole was observed, with most resistance among historic isolates of serotype 7 and least resistance among isolates from Sweden. A large number of the isolates was resistant to macrolides. However, all historic serotype 2 isolates from Denmark were susceptible, whereas 20.4% of the contemporary isolates were resistant. Among serotype 7 isolates 23.3% of the historic isolates were resistant to macrolides, whereas resistance was found in 44.8% of the contemporary isolates. All isolates from Sweden were susceptible to macrolides. Time-associated frequency of resistance to tetracycline was also found. Only a single historic isolate of serotype 2 was resistant to tetracycline, whereas 43.9% of the contemporary serotype 2 isolates and 15.5% of the contemporary serotype 7 isolates were resistant. Only one (7.7%) of the isolates from Sweden was resistant. The differences in resistance between historic and contemporary isolates from Denmark were statistically significant. This study demonstrated a significant serotype-associated difference in the susceptibility to macrolides and tetracycline and demonstrated that an increase in resistance among S. suis isolates has taken place during the last 15 years to the two most commonly used antimicrobial agents (tylosin and tetracycline) in pig production in Denmark.

    An overview of the current understanding of ozone depletion chemistry, particularly with regards the formation of the so-called Antarctic ozone hole, will be presented together with an outline as to how ab initio quantum chemistry can be used to further our understanding of stratospheric chemistry. The ability of modern state-of-the art ab initio quantum chemical techniques to characterize reliably the gas-phase molecular structure, vibrational spectrum, electronic spectrum, and thermal stability of fluorine, chlorine, bromine and nitrogen oxide species will be demonstrated by presentation of some example studies. The ab initio results will be shown to be in excellent agreement with the available experimental data, and where the experimental data are either not known or are inconclusive, the theoretical results are shown to fill in the gaps and to resolve experimental controversies. In addition, ab initio studies in which the electronic spectra and the characterization of excited electronic states of halogen oxide species will also be presented. Again where available, the ab initio results are compared to experimental observations, and are used to aid in the interpretation of experimental studies.

    2004-09-24

    Quantum mechanical-based (or ab initio) methods are used to predict the stability properties of materials although their application is limited to relatively simple systems in terms of structures and number of alloy components. However thermodynamics of complex multi-component alloys requires a more versatile approach afforded within the CALPHAD formalism. Despite its success, the lack of experimental data very often prevents the design of robust thermodynamic databases. After a brief survey of ab initio methodologies and CALPHAD, it will be shown how ab initio electronic structure methods can supplement in two ways CALPHAD for subsequent applications. The first one is rather immediate and concerns the direct input of ab initio energetics in CALPHAD databases. The other way, more involved, is the assessment of ab initio thermodynamics '{acute a} la CALPHAD'. It will be shown how these results can be used within CALPHAD to predict the equilibrium properties of multi-component alloys. Finally, comments will be made on challenges and future prospects.

  15. The Over-Expression of Two Transcription Factors, ABS5/bHLH30 and ABS7/MYB101, Leads to Upwardly Curly Leaves

    Proper leaf development is essential for plant growth and development, and leaf morphogenesis is under the control of intricate networks of genetic and environmental cues. We are interested in dissecting these regulatory circuits genetically and report here the isolation of two Arabidopsis dominant mutants, abnormal shoot5-1D (abs5-1D) and abs7-1D identified through activation tagging screens. Both abs5-1D and abs7-1D display an intriguing upwardly curly leaf phenotype. Molecular cloning showed that the elevated expression of a bHLH transcription factor ABS5/T5L1/bHLH30 or a MYB transcription factor ABS7/MYB101 is the cause for the abnormal leaf phenotypes found in abs5-1D or abs7-1D, respectively. Protoplast transient expression assays confirmed that both ABS5/T5L1 and ABS7/MYB101 are targeted to the nucleus. Interestingly, the expression domains of auxin response reporter DR5::GUS were abnormal in leaves of abs5-1D and ABS5/T5L1 over-expression lines. Moreover, cotyledon venation analysis showed that more areoles and free-ending veins are formed in abs5-1D. We found that the epidermis-specific expressions of ABS5/T5L1 or ABS7/MYB101 driven by the Arabidopsis Meristem Layer 1 promoter (PAtML1) were sufficient to recapitulate the curly leaf phenotype of abs5-1D or abs7-1D. In addition, PAtML1::ABS5 lines exhibited similar changes in DR5::GUS expression patterns as those found in 35S-driven ABS5/T5L1 over-expression lines. Our work demonstrated that enhanced expressions of two transcription factors, ABS5/T5L1 and ABS7/MYB101, are able to alter leaf lamina development and reinforce the notion that leaf epidermis plays critical roles in regulating plant organ morphogenesis.

  16. Surface expression of intraplate postglacial faults in Sweden: from LiDAR data

    Large intraplate earthquakes, up to magnitude 8.0±0.3 (Lindblom et al. 2015) are inferred to have occurred in northern Fennoscandia at the end of, or just after the Weichselian deglaciation. More than a dozen large so-called postglacial faults (PGF) have been found in the region. The present-day microseismic activity is rather high in north Sweden, and there is a correlation between microseismicity and mapped PGF scarps: 71% of the observed earthquakes north of 66°N locate within 30 km to the southeast and 10 km to the northwest of PGFs (Lindblom et al., 2015). Surface expressions of PGFs in Sweden have mainly been mapped using aerial photogrammetry and trenching (e.g. Lagerbäck & Sundh 2008). Their detailed surface geometry may be investigated using the new high-resolution elevation model of Sweden (NNH) that has a vertical- and lateral resolution of 2 m and 0.25 m, respectively. With NNH data, known PGFs have been modified, and a number of new potential PGFs have been identified (Smith et al. 2014; Mikko et al. 2015). However, the detailed variation of their surface expression remains to be determined. Our main objective is to constrain the strike and surface offset (i.e., apparent vertical throw because of soil cover overlays the bedrock) across the PGF scarps. We anticipate using the results to constrain direction of fault motion and paleomagnitudes of PGFs, and in numerical analyzes to investigate the nature of PGFs. We have developed a methodology for analyzing PGF-geomorphology from LiDAR data using two main software platforms (Ask et al. 2015): (1) Move2015 by Midland Valley has been used for constructing 3D models of the surface traces of the PGFs to determine apparent vertical throw. The apparent hanging- and footwall cut off lines are digitized, and subsequent computation of coordinates is rather time efficient and provide continuous data of fault and soil geomorphology that can be statistically analyzed; and (2) ArcGIS 10.3 by Esri has mostly been

Such an implementation allows us to model transport phenomena in rarefied gases without any fitting parameter of intermolecular collisions usually extracted from experimental data. Applying the method proposed by Sharipov and Strapasson [Phys. Fluids 24, 011703 (2012)], the use of ab initio potentials in the DSMC requires the same computational efforts as the widely used potentials such as hard spheres, variable hard sphere, variable soft spheres, etc. At the same time, the ab initio potentials provide more reliable results than any other one. As an example, the transport coefficients of a binary mixture He-Ar, viz., viscosity, thermal conductivity, and thermal diffusion factor, have been calculated for several values of the mole fraction.

    Helicases play critical roles in all aspects of nucleic acid metabolism by catalyzing the remodeling of DNA and RNA structures. UvrD is an abundant helicase in Escherichia coli with well characterized functions in mismatch and nucleotide excision repair and a possible role in displacement of proteins such as RecA from single-stranded DNA. The mismatch repair protein MutL is known to stimulate UvrD. Here we show that the nucleotide excision repair proteins UvrA and UvrB can together stimulate UvrD-catalyzed unwinding of a range of DNA substrates containing strand discontinuities, including forked DNA substrates. The stimulation is specific for UvrD, as UvrAB failed to stimulate Rep helicase, a UvrD homologue. Moreover, although UvrAB can promote limited strand displacement, stimulation of UvrD did not require the strand displacement function of UvrAB. We conclude that UvrAB, like MutL, modulate UvrD helicase activity. This stimulation likely plays a role in DNA strand and protein displacement by UvrD in nucleotide excision repair. Promotion of UvrD-catalyzed unwinding of nicked duplexes by UvrAB may also explain the need for UvrAB and UvrD in Okazaki fragment processing in cells lacking DNA polymerase I. More generally, these data support the idea that helicase activity is regulated in vivo, with helicases acting as part of multisubunit complexes rather than in isolation. PMID:19208629

    Ab initio computations, have already been used to examine the energetics of the photodissociation of stratospheric chlorofluorocarbons. Our awn research has investigated the ab initio computation of vibrational frequencies and infrared intensities of CF{sub 3}CH{sub 2}F, CF{sub 3}CF{sub 2}H, and CF{sub 3}CH{sub 3}; continuing research will attempt to expand these computations to the energetics of the photodissociation of these molecules, since sane of the most common types of chlorofluorocarbon substitutes are hydrofluoroethanes.

  20. An ABS control logic based on wheel force measurement

    The paper presents an anti-lock braking system (ABS) control logic based on the measurement of the longitudinal forces at the hub bearings. The availability of force information allows to design a logic that does not rely on the estimation of the tyre-road friction coefficient, since it continuously tries to exploit the maximum longitudinal tyre force. The logic is designed by means of computer simulation and then tested on a specific hardware in the loop test bench: the experimental results confirm that measured wheel force can lead to a significant improvement of the ABS performances in terms of stopping distance also in the presence of road with variable friction coefficient.

  1. Ab Initio Structure Analysis Using Laboratory Powder Diffraction Data

    Sasaki, Akito

    Today, laboratory X-ray diffractometers are seeing increasingly wide use in the ab initio crystal structure analysis of organic powder samples. This is because optics and optical devices have been improved, making it possible to obtain precise integrated intensities of reflections in high 2-theta ranges. Another reason is that one can use direct-space methods, which do not require “high-resolution diffraction data”, much more easily than before. Described here are some key points to remember when performig ab initio crystal structure analysis using powder diffraction data from organic compounds.

    Very wide binaries are interesting objects that shed light on the binary formation process and their dynamical evolution. Poveda et al. (2009) studied the possible physical relation of the near (14.2 pc) and wide (~58") binary star GJ 282 AB and the extremely wide (1.09º; ~55,000 AU) companion, NLTT 18149, and they concluded that this very wide system is in the process of dynamical disintegration. In this work, we confirm the same conclusion but using a different method. We first study dynamically GJ 282 AB, confirmed that it is a bound system and then we determine possible orbital solutions. Later, we calculate the relative velocity of NLTT 18149 with respect to the GJ 282 AB's center mass using their (U, V, W) galactocentric velocity. The relative velocity, Vrel = 1.98 ± 0.16 km s-1, is much larger than the escape velocity (0.25 ± 0.01 km s-1). Therefore, with a significance level of 11s, we also conclude that this very wide system is in a process of dynamical disintegration.

    This review provides an overview of the development, implementation and practise of low protein diets (LPD) in Sweden. While the current practice is discussed in general terms emphasizing the interplay between nephrologists and dieticians, the "self-selected" LPD model is explained as a practical approach to facilitated patient's adherence to the nutritional therapy. This model is currently implemented in most clinics of the country and gives considerable flexibility regarding variation in meal planning, food selection, amounts consumed, cooking methods as well as adaptations to day-to-day changes. Current LPD use in Sweden is presented through analysis of the Swedish Renal Registry. Finally two patient cases are illustrated, with examples on their diets, attempts to reduce the protein content to the desired thresholds and their clinical course. PMID:27435012

    Surveillance was enhanced and a retrospective interview study performed in 1998-99 to determine incidence, causes, and costs of foodborne illnesses in Uppsala, Sweden. Sixty-eight percent of the detected foodborne illness incidents were single cases, and 32% were outbreaks. Most (85%) of the incidents came to the attention of the municipal authorities through telephone calls from affected persons. Calicivirus, Campylobacter spp., and Staphyloccocus aureus were the most common etiological agents; meat, meat products, and mixed dishes were the most implicated food categories. The incidence of foodborne illness was estimated to be 38 cases per 1,000 inhabitants per year. The estimated average costs per illness were 2,164 Swedish Krona (SEK) ($246) to society and 500 SEK ($57) to the patient. The annual cost of foodborne illnesses in Sweden was estimated to be 1,082 million SEK ($123 million). PMID:11485680

    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. PMID:25373497

    Genetic testing is becoming more commonplace in general and specialist health care and should always be accompanied by genetic counselling, according to Swedish law. Genetic counsellors are members of the multi-disciplinary team providing genetic counselling. This study examined the role and added value of genetic counsellors in Sweden, using a cross-sectional on-line survey. The findings showed that the genetic counsellors added value in the clinical setting by acting as the 'spider-in-the-web' regarding case management, having a more holistic, ethical and psychological perspective, being able to offer continuous support and build a relationship with the patient, and being more accessible than medical geneticists. The main difference between a genetic counsellor and medical geneticist was that the doctor had the main medical responsibility. Thus genetic counsellors in Sweden contribute substantially to the care of patients in the clinical genetic setting. PMID:26014428

    "The conditions for young immigrants in the Swedish labour market have been widely discussed in recent years. One hypothesis put forward is that young immigrants tend to remain in jobs with low wages, high risks of unemployment and bad working environments, and their mobility out of such jobs is low.... Because composition of the immigrant group, through immigration and re-emigration, changes over time, the use of longitudinal studies is especially useful. However, only a few such studies have been conducted in Sweden, none of which gives special attention to the labour market careers of immigrant youth. The aim of this paper is to remedy this deficiency by using comprehensive longitudinal data for the period 1970 to 1990. Finnish-born youth were selected for study because they are the largest immigrant group in Sweden." (SUMMARY IN FRE AND SPA) PMID:12292231

  9. State policy, popular discourse, and the silence on homosexual acts in early modern Sweden.

    PubMed

    Liliequist, J

    1998-01-01

    In Sweden, homosexual acts between men were mentioned in secular law for the first time in 1608. Despite the explicit criminalization, very few trials are known from the seventeenth and eighteenth centuries, and the new National Law Code of 1734 contained no sanction at all. The central issue of this essay is how the insignificant number of court cases and the seemingly very limited judicial interest in the issue of sodomy in Early Modern Sweden should be interpreted. The silence of the new law is explained by a shift in the official policy from deterrence to a policy of silence, but the low number of court cases was foremost dependent on a lacking actualization and problematization of homosexual acts in the Swedish popular discourse on sexuality, gender, and prestige. Finally, it is argued that this undeveloped popular discourse probably also corresponded to a meagre and rather restricted sexual practice. PMID:9638557

    Strikes by junior hospital doctors over the issue of on-call remuneration in Denmark and Sweden in 1981 are analyzed to clarify the impact of public-sector cost-control policies on intra- and interprofessional solidarity within the Scandinavian professional peak associations. The junior doctors' grievances could find expression either through increased "voice" within the medical negotiating machinery, or by pursuing the exit option in having the medical associations quit the peak associations. The article explains why the "exit" option was selected in Denmark, while in Sweden the granting of additional voice helped persuade the medical association to withdraw its exit threat and to remain within the peak association. The two cases are interpreted as presaging a divergence in the paths being taken by the various Scandinavian welfare states. PMID:4045171

    As humans alter landscape, vegetation, climate and atmospheric composition, changes in the terrestrial water balance and fresh water resources are likely to occur. Understanding how climate, vegetation, humans and hydrology interact and feedback to the atmosphere is key for accurate projections of future fresh water resources. To this end, we will present the results of a data-driven regionalization approach for river discharges, using 280 river discharge and over 400 meteorological records (1960-2010) in Sweden. We related catchment runoff coefficients and change trends thereof to land-surface characteristics. With these relationships we were able to create average and change trend maps for runoff and evapotranspiration across Sweden. We summarized all this information by plotting water use efficiency (actual evapotranspiration (ET)/precipitation) against energy use efficiency (actual ET/potential ET by Priestley Taylor Eq.) for areas with unique land cover across Sweden. This plot clearly shows that wetlands tend to have lower water and energy use efficiencies compared to "open waters", forests and agriculture, and that agriculture has water and energy use efficiencies closest to those of "open waters". These results demonstrate how a change in land cover driven by climate change or by humans is likely to alter land-cover-atmosphere interactions, thereby changing both the water and energy balance of catchments. Looking at the change trends during the last 50 years we see that the vegetation tended to become more efficient in using water and energy (i.e. the fractions of water and energy converted into river runoff and heat decreased). As this behavior coincides with an increase in precipitation it signals an acceleration of the hydrological across Sweden. In this presentation we will discuss the potential mechanisms explaining this increase in efficiency and discuss the implications of our findings for future water cycles.

  13. A roadmap for climate change adaptation in Sweden's forests: addressing wicked problems using adaptive management

    Climate change is expected to have significant direct and indirect effects on forest ecosystems. Forests will have to adapt not only to changes in mean climate variables but also to increased climatic variability and altered disturbance regimes. Rates of change will likely exceed many forests capabilities to naturally adapt and many of today's trees will be exposed to the climates of 2090. In Sweden the effects are already being seen and more severe impacts are expected in the future. Exacerbating the challenge posed by climate change, a large proportion of Sweden's forests are, as a consequence of dominant production goals, greatly simplified and thus potentially more vulnerable to the uncertainties and risks associated with climate change. This simplification also confers reduced adaptive capacity to respond to potential impacts. Furthermore, many adaptation measures themselves carry uncertainties and risks. Future changes and effects are thus uncertain, yet forest managers, policymakers, scientists and other stakeholders must act. Strategies that build social and ecological resilience in the face of multiple interacting unknowns and surprises are needed. Adaptive management aims to collect and integrate knowledge about how a managed system is likely to respond to alternative management schemes and changing environmental conditions within a continuous decision process. There have been suggestions that adaptive management is not well suited to the large complex uncertainties associated with climate change and associated adaptation measures. However, more recently it has been suggested that adaptive management can handle such wicked problems, given adequate resources and a suitable breakdown of the targeted uncertainties. Here we test this hypothesis by evaluating how an adaptive management process could be used to manage the uncertainties and risks associated with securing resilient, biodiverse and productive forests in Sweden in the face of climate change.

    A random selection of 25 strains isolated during an epidemic caused by serogroup A Neisseria meningitidis in Sudan (1988), 3 preepidemic meningococcal strains (1985), and 26 serogroup A strains isolated from sporadic cases of meningitis in Sweden (1973 to 1987) were assessed for multilocus enzyme genotypes (ETs), DNA restriction enzyme patterns, outer membrane proteins, lipopolysaccharides, pilus formation, and antibiograms. All of the 25 Sudanese epidemic isolates and 22 of the Swedish strains were of the same or closely related ETs (ETs 3, 4, and 5), corresponding to clone III-1, which has been responsible for two pandemic waves in the last three decades. The earlier pandemic involved Scandinavia, and the last one caused an outbreak during the pilgrimage to Mecca, Saudi Arabia (August 1987), spreading to Sudan, Chad, and Ethiopia. The three Sudanese preepidemic isolates (1985) were clone IV-1 (sulfonamide susceptible), which has been resident in the African meningitis belt for the last 25 years. The uniformity of clone III-1 strains (all sulfonamide resistant) from Sudan and Sweden was confirmed by DNA restriction enzyme patterns. ETs 3, 4, and 5 from Sudan and Sweden had 86 to 100% similarity to a Swedish clone III-1 reference strain, whereas ETs 1, 2, 6, and 7 showed 50 to 80% similarity. Class 1 protein for clone III-1 showed serosubtype antigens P1.9 and P1.x, whereas ET6 strains (clone IV-1) had serosubtype P1.7. Lipopolysaccharides were variable in the Sudanese and Swedish strains. Pili were expressed in all clone III-1 isolates from Sudan and Sweden but in none of the clone IV-1 isolates (Sudan, 1985).

    Purpose - The purpose of this paper is to identify opportunities for improving primary care services for people with chronic illnesses by comparing how Sweden and US services use evidence-based practices (EBPs), including digital health technologies (DHTs). Design/methodology/approach - A national primary healthcare center (PHCC) heads surveys in 2012-2013 carried out in both countries in 2006. Findings - There are large variations between the two countries. The largest, regarding effective DHT use in primary care centers, were that few Swedish primary healthcare compared to US heads reported having reminders or prompts at the point of care (38 percent Sweden vs 84 percent USA), despite Sweden's established electronic medical records (EMR). Swedish heads also reported 30 percent fewer centers receiving laboratory results (67 percent Sweden vs 97 percent USA). Regarding following other EBPs, 70 percent of Swedish center heads reported their physicians had easy access to diabetic patient lists compared to 14 percent in the USA. Most Swedish PHCC heads (96 percent) said they offered same day appointment compared to 36 percent in equivalent US practices. Practical implications - There are opportunities for improvement based on significant differences in effective practices between the countries, which demonstrates to primary care leaders that their peers elsewhere potentially provide better care for people with chronic illnesses. Some improvements are under primary care center control and can be made quickly. There is evidence that people with chronic illnesses in these two countries are suffering unnecessarily owing to primary care staff failing to provide proven EBP, which would better meet patient needs. Public finance has been invested in DHT, which are not being used to their full potential. Originality/value - The study shows the gaps between current and potential proven effective EBPs for services to patients with chronic conditions. Findings suggest possible

    Background. Age-specific incidence rates for breast cancer in low-risk and high-risk ethnic populations differ by age at which the incidence maximum is reached: around 50 years in low-risk populations and over 60 years in high-risk populations. The interpretation of these differences remains unsettled, one line primarily referring to biological differences, the second one to cohort effects of rapidly increasing rates in young populations, and the third one to incomplete registration of cancer in the elderly. Methods. The nationwide Family-Cancer Database was used to analyze standardized incidence ratios (SIRs) and age at diagnosis of breast cancer in female immigrants to Sweden by their region of origin compared with women native to Sweden matched on birth year and other relevant factors. Results. We showed first that the SIRs for breast cancer were lower in many immigrant groups compared with natives of Sweden; women from Turkey had the lowest SIR of 0.45, followed by those from Chile (0.54) and Southeast Asia (0.57). Women from nine regions showed an earlier mean age at diagnosis than their matched Swedish controls, the largest differences being 5.5 years for women from Turkey, 5.1 years for those from Asian Arab and “Other African” countries, 4.3 years for those from Iran, and 4.0 years for those from Iraq. Conclusions. The results show that in many immigrant groups, the diagnostic age is earlier (<50 years) than in natives of Sweden (>50 years), suggesting that true biological factors underlie the differences. These factors may explain much of the international variation in breast cancer incidence. Identifying these factors should advance understanding of breast cancer etiology and prevention.

    Between 1996 and 2002, the Swedish import of so-called yellow waste for energy recovery increased. The import mainly consisted of separated wood waste and mixes of used wood and paper and/or plastics that was combusted in district heat production plants (DHPPs). Some mixed waste was imported to waste incineration plants for energy recovery (10% of the import of yellow waste for energy recovery in 2002). The import came primarily from Germany, the Netherlands, Norway, Denmark and Finland. We identified six underlying driving forces for this recent increase of imported waste which are outlined and their interactive issues discussed. --The energy system infrastructure, which enables high energy recovery in Sweden. --The energy taxation, where high Swedish taxes on fossil fuels make relatively expensive solid biofuels the main alternative for base load production of district heat. --The quality of the waste-derived fuels, which has been higher in the exporting countries than in Sweden. --The bans on landfilling within Europe and the shortage of waste treatment capacity. --Taxes on waste management in Europe. --Gate fee differences between exporting countries and Sweden. In the future, the overall strength of these driving forces will probably be weakened. A Swedish tax on waste incineration is being investigated. In other European countries, the ambition to reach the Kyoto targets and increase the renewable electricity production could improve the competitiveness of waste-derived fuels in comparison with fossil fuels. Swedish DHPPs using waste-derived fuels will experience higher costs after the Waste Incineration Directive is fully implemented. The uncertainty about European waste generation and treatment capacity, however, might have a large influence on the future gate fees and thus also on the yellow waste import into Sweden.

    Comparative research on parenting styles among Nordic and Mediterranean countries is still missing, despite the increasing number of studies on parenting styles in adolescence. This study explores similarities and differences in adolescents’ retrospective perceptions of parenting styles, for both parents, in Sweden, Italy and Greece, using the Parenting Styles and Dimensions Questionnaire. In particular, it examines the relation between parental role, adolescent gender, country of origin, SES and these perceptions. Swedish, Italian and Greek adolescents (N = 702; 30.9% Swedish, 39.6% Italian and 29.5% Greek) participated in the study. To test the principal effects three mixed 2(parent; mother and father)*2(gender; girl and boy)*3(countries; Sweden, Italy and Greece)*3(SES; low, medium and high) ANOVAs were conducted separately for each parenting style. To verify the interaction effects, a mixed 2(parent; mother and father)*3(countries; Sweden, Italy and Greece)*3(SES; low, medium and high) ANOVA was tested on authoritative style. Regarding authoritarian and permissive two mixed 2(parent; mother and father)*2(gender; girl and boy)*3(countries; Sweden, Italy and Greece) ANOVAs were tested. Mothers, as compared to fathers, were perceived as more authoritative, authoritarian and permissive. Moreover, boys perceived their parents as more authoritarian and more permissive than girls. Swedish parents were perceived as significantly less authoritarian than Italian and Greek parents and more permissive than Italian parents; Greek parents were perceived as less authoritarian and more permissive than Italian parents. The study provides an interesting contribution to parenting styles literature, showing how country legislation concerning family matters and SES are related the perception of parenting behaviours.

    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.

Mothers, as compared to fathers, were perceived as more authoritative, authoritarian and permissive. Moreover, boys perceived their parents as more authoritarian and more permissive than girls. Swedish parents were perceived as significantly less authoritarian than Italian and Greek parents and more permissive than Italian parents; Greek parents were perceived as less authoritarian and more permissive than Italian parents. The study provides an interesting contribution to parenting styles literature, showing how country legislation concerning family matters and SES are related the perception of parenting behaviours.

    A simple method to estimate the atomic degree Hessian matrixof a nanosystem is presented. The estimated Hessian matrix, based on themotif decomposition of the nanosystem, can be used to accelerate abinitio atomic relaxations with speedups of 2 to 4 depending on the sizeof the system. In addition, the programing implementation for using thismethod in a standard ab initio package is trivial.

    Nickel electroplating of acrylonitrile butadiene styrene (ABS) plastic has been achieved successfully without any chromium or palladium pretreatment. Once the ABS is coated with polypyrrole (PPy), the sample may be electroplated. The process is fast, economic and involves three stages. Firstly, chemical deposition of PPy on ABS, secondly, copper deposition and finally nickel electroplating. A homogenous and adherent PPy has been synthesized chemically on ABS plate by using pyrrole as monomer and iron (III) chloride as oxidant. Copper and nickel were deposited galvanostatically from industrial plating baths. The metallic coatings were homogeneous and the adherence was estimated at 100%. The thickness of copper and nickel depend on the electrolysis time. As the current density increases, the Cu and Ni thickness raises. This result was confirmed from SEM characterization and RX map. The Ni coating is characterized by a globular structure with globules of different sizes. Energy dispersive X-ray spectroscopy (EDS) analysis shows the presence of Ni with some amount of carbon and oxygen due to the nickel oxides and contaminant from the bath solution.

    Multiple time-scale algorithms exploit the natural separation of time-scales in chemical systems to greatly accelerate the efficiency of molecular dynamics simulations. Although the utility of these methods in systems where the interactions are described by empirical potentials is now well established, their application to ab initio molecular dynamics calculations has been limited by difficulties associated with splitting the ab initio potential into fast and slowly varying components. Here we present two schemes that enable efficient time-scale separation in ab initio calculations: one based on fragment decomposition and the other on range separation of the Coulomb operator in the electronic Hamiltonian. We demonstrate for both water clusters and a solvated hydroxide ion that multiple time-scale molecular dynamics allows for outer time steps of 2.5 fs, which are as large as those obtained when such schemes are applied to empirical potentials, while still allowing for bonds to be broken and reformed throughout the dynamics. This permits computational speedups of up to 4.4x, compared to standard Born-Oppenheimer ab initio molecular dynamics with a 0.5 fs time step, while maintaining the same energy conservation and accuracy.

    Modeling and simulation research on automobile ABS bench detection is conducted in this paper. First, the vehicle model, wheel model, braking force model, and tire-road model on the bench are established according to the ABS bench detection scheme. Then, the Matlab/Simulink simulation model of a single wheel vehicle is built through combining the sub-models described above. Finally, simulation experiments on a variety of simulated road conditions are carried out. And the comparative analysis between the ABS bench detection and ABS road experiments is accomplished. The contrast results show that the simulation curves of bench detection and those of road experiment have high similarity, which verified the correctness and feasibility of the proposed bench detection scheme. At the request of the authors this article is being retracted. It was inadvertently published in AIP Conf.

    Sindbis virus (SINV) is a mosquito-borne bird virus that occasionally causes human disease in Fennoscandia, suggested to have cyclic 7-year intervals between outbreaks. Reliable data on human infections in Sweden is however lacking. Here we investigated the SINV antibody prevalence among birds in a Swedish area endemic to SINV to scrutinize if a cyclic variation in antibody prevalence is present in the natural host of SINV. Serum from birds were sampled in the summers of 2002-2004 and 2009 in the floodplains of the River Dalälven in central Sweden, with 2002 and 2009 representing hypothesized years of SINV outbreaks. A total of 963 birds from 52 species (mainly passerines) were tested for the presence of SINV antibodies using a plaque reduction neutralization test. The highest SINV antibody prevalence was found in Turdidae species, specifically Fieldfare, Redwing and Song thrush in which more than 70% of sampled individuals had antibodies to SINV in 2009. The SINV antibody prevalence significantly varied between years with 2% in 2002, 8% in 2003, 14% in 2004 and 37% in 2009. Antibodies were found equally often in hatchlings and in adults and increased from early to late in the season. Clearly, the SINV antibody prevalence was not elevated in the bird hosts in the predicted outbreak year 2002, thus solid evidence of a cyclic occurrence of SINV in Sweden is still lacking.

    2014-01-01

    Background Establishment of haematological and biochemical reference intervals is important to assess health of animals on individual and population level. Reference intervals for 13 haematological and 34 biochemical variables were established based on 88 apparently healthy free-ranging brown bears (39 males and 49 females) in Sweden. The animals were chemically immobilised by darting from a helicopter with a combination of medetomidine, tiletamine and zolazepam in April and May 2006–2012 in the county of Dalarna, Sweden. Venous blood samples were collected during anaesthesia for radio collaring and marking for ecological studies. For each of the variables, the reference interval was described based on the 95% confidence interval, and differences due to host characteristics sex and age were included if detected. To our knowledge, this is the first report of reference intervals for free-ranging brown bears in Sweden. Results The following variables were not affected by host characteristics: red blood cell, white blood cell, monocyte and platelet count, alanine transaminase, amylase, bilirubin, free fatty acids, glucose, calcium, chloride, potassium, and cortisol. Age differences were seen for the majority of the haematological variables, whereas sex influenced only mean corpuscular haemoglobin concentration, aspartate aminotransferase, lipase, lactate dehydrogenase, β-globulin, bile acids, triglycerides and sodium. Conclusions The biochemical and haematological reference intervals provided and the differences due to host factors age and gender can be useful for evaluation of health status in free-ranging European brown bears.

    1995-03-01

    The effects of climate change on the water balance of Scots pine were studied with a coupled water and heat flow model called 'SOIL'. Two forest soil types (a silty-sand and a sand) at five locations in Sweden were chosen to represent sites with different air temperature, growing season length and precipitation excess. The simulated water balance for the period 1961-1987 was compared with those simulated with two climate change scenario schemes: one is based on increased temperature and the other on both increased temperature and increased precipitation. Different assumptions regarding the effects of changes in leaf area index and minimum canopy resistance on transpiration were studied. Water stress increased substantially in the scenarios based on increased temperature only, which prevented transpiration from increasing. But with scenarios based on simultaneous changes in temperature and precipitation, water stress increased mainly during spring and transpiration increased by 50 mm and 100 mm in northern and southern Sweden, respectively, i.e. by 30-50%. When simultaneous changes in climate and stand characteristics were assumed, transpiration increased by 30-70% with the relative change being greatest for northern Sweden. Differences in water balance between the locations and soil types were less pronounced in the climate change scenarios than in the present climate scenario.

    Isolates of Listeria monocytogenes (n = 932) isolated in Sweden during 1958-2010 from human patients with invasive listeriosis were characterized by serotyping and pulsed-field gel electrophoresis (PFGE) (AscI). Of the 932 isolates, 183 different PFGE types were identified, of which 83 were each represented by only one isolate. In all, 483 serovar 1/2a isolates were distributed over 114 PFGE types; 90 serovar 1/2b isolates gave 32 PFGE types; 21 serovar 1/2c isolates gave nine PFGE types; three serovar 3b isolates gave one PFGE type; and, 335 serovar 4b isolates gave 31 PFGE types. During the 1980s in Sweden, several serovar 4b cases were associated with the consumption of European raw soft cheese. However, as cheese-production hygiene has improved, the number of 4b cases has decreased. Since 1996, serovar 1/2a has been the dominant L. monocytogenes serovar in human listeriosis in Sweden. Therefore, based on current serovars and PFGE types, an association between human cases of listeriosis and the consumption of vacuum-packed gravad and cold-smoked salmon is suggested. PMID:24480252

    An increase of invasive meningococcal disease caused by Neisseria meningitidis serogroup Y has been noted in Sweden since 2005, and to a lower extent throughout Europe. The present study describes the epidemiology of invasive N. meningitidis isolates in Sweden in the period between 2010 and 2012, with a focus on serogroup Y. We also aimed to find an optimal molecular typing scheme for both surveillance and outbreak investigations. All invasive N. meningitidis isolates in Sweden during the study period (n=208) were genetically characterised. Serogroup Y predominated with 22/57, 31/61 and 44/90 of all invasive isolates (incidence 0.23, 0.33 and 0.46 per 100,000 population) in 2010, 2011 and 2012 respectively. In each of these years, 15/22, 22/31 and 19/44 of serogroup Y isolates were genetically clonal (Y: P1.5–2,10–1,36–2: F4–1: ST-23(cc23), ‘porB allele 3–36, fHbp allele 25 and penA allele 22). Our findings further support those of others that currently recommended FetA typing could be replaced by FHbp. Moreover, in line with a previous study that we conducted, the current results indicate that highly variable multilocus variable-number tandem repeat analysis (HV-MLVA) can be used as a first-hand rapid method for small outbreak investigations.

    Domestication of animals and plants marked a turning point in human prehistory. To date archaeology, archaeozoology and genetics have shed light on when and where all of our major livestock species were domesticated. Phenotypic changes associated with domestication have occurred in all farm animals. Coat colour is one of the traits that have been subjected to the strongest human selection throughout history. Here we use genotyping of coat colour SNPs in horses to investigate whether there were any regional differences or preferences for specific colours associated with specific cultural traditions in Iron Age Sweden. We do this by identifying the sex and coat colour of horses sacrificed at Skedemosse, Öland (Sweden) during the Iron Age, as well as in horses from two sites in Uppland, Ultuna and Valsgärde (dated to late Iron Age). We show that bay, black and chestnut colours were all common and two horses with tobiano spotting were found. We also show how the combination of sex identification with genotyping of just a few SNPs underlying the basic coat colours can be used to identify the minimum number of individuals at a site on a higher level than morphological methods alone. Although separated by 500 km and from significantly different archaeological contexts the horses at Skedemosse and Ultuna are quite homogenous when it comes to coat colour phenotypes, indicating that there were no clear geographical variation in coat colouration in Sweden during the late Iron Age and early Viking Age.

    1998-10-01

    This paper compares policies on named HIV testing in the context of HIV prevention in Britain, Hungary and Sweden, and considers the extent to which these policies are based on evidence of effectiveness or on other, more contextual, factors. In Britain, testing has not featured significantly as a prevention strategy, and named testing has generally been carried out only with the voluntary, informed consent of individuals. In Hungary, testing is central to HIV prevention, and is required by law of certain groups. HIV testing is carried out mainly on a voluntary basis in Sweden, but, unlike in Britain, it has been actively promoted by public health authorities. The paper contrasts the 'right not to know' one's HIV status which is widely respected in Britain, with the 'responsibility to find out' which is more pervasive in Hungary and Sweden. Although policy makers in all three countries appear convinced that their's is the right approach, there appears to be as yet a dearth of convincing evidence to support their arguments. PMID:9828953

    We report new Zeeman--Doppler imaging observations of the rapidly rotating young K0 dwarf AB Doradus, obtained with the Anglo-Australian Telescope in 1996 December. From such observations, simultaneous brightness and magnetic images of the stellar photosphere of AB Dor were reconstructed at three different epochs. The magnetic topology of AB Dor is found to be very complex, with at least 12 different radial field regions of opposite polarities located all around the star. Significant azimuthal field fluxes are also detected in the form of one negative polarity region close to the equator, a series of positive polarity patches at intermediate latitudes and an almost complete ring of negative polarity encircling the rotational pole at high latitudes. In particular, the azimuthal polarities we reconstruct are in very good agreement with those obtained by Donati & Cameron, confirming that this field component is directly related to the dynamo-generated large-scale toroidal magnetic structure. The triple polarity latitudinal pattern observed for this structure in the upper hemisphere of AB Dor indicates that the degree of the underlying large-scale poloidal structure in an axisymmetric spherical harmonics expansion is equal to or greater than five. It also strengthens the idea that the dynamo processes operating in AB Dor feature a non-solar component distributed throughout the convective zone. From the subtle distortion of successive brightness images, we can also confirm the surface differential rotation first measured on this star by Donati & Cameron in both sense and magnitude, with a pole rotating more slowly than the equator by about one part in 220. Finally, the rotation periods we measure for four prominences (from the recurrence rate of their spectral signatures in Balmer lines) confirm the presumption that such clouds are anchored at intermediate to high latitudes. The intrinsic variability of these prominences is not associated with any abrupt changes in the

  4. Changes in the geographical distribution and abundance of the tick Ixodes ricinus during the past 30 years in Sweden

    PubMed Central

    2012-01-01

    Background Ixodes ricinus is the main vector in Europe of human-pathogenic Lyme borreliosis (LB) spirochaetes, the tick-borne encephalitis virus (TBEV) and other pathogens of humans and domesticated mammals. The results of a previous 1994 questionnaire, directed at people living in Central and North Sweden (Svealand and Norrland) and aiming to gather information about tick exposure for humans and domestic animals, suggested that Ixodes ricinus ticks had become more widespread in Central Sweden and the southern part of North Sweden from the early 1980s to the early 1990s. To investigate whether the expansion of the tick's northern geographical range and the increasing abundance of ticks in Sweden were still occurring, in 2009 we performed a follow-up survey 16 years after the initial study. Methods A questionnaire similar to the one used in the 1994 study was published in Swedish magazines aimed at dog owners, home owners, and hunters. The questionnaire was published together with a popular science article about the tick's biology and role as a pathogen vector in Sweden. The magazines were selected to get information from people familiar with ticks and who spend time in areas where ticks might be present. Results Analyses of data from both surveys revealed that during the near 30-year period from the early 1980s to 2008, I. ricinus has expanded its distribution range northwards. In the early 1990s ticks were found in new areas along the northern coastline of the Baltic Sea, while in the 2009 study, ticks were reported for the first time from many locations in North Sweden. This included locations as far north as 66°N and places in the interior part of North Sweden. During this 16-year period the tick's range in Sweden was estimated to have increased by 9.9%. Most of the range expansion occurred in North Sweden (north of 60°N) where the tick's coverage area doubled from 12.5% in the early 1990s to 26.8% in 2008. Moreover, according to the respondents, the abundance

    Background Telemonitoring of heart failure (HF) patients is increasingly discussed at conferences and addressed in research. However, little is known about actual use in specific countries. Objective We aimed to (1) describe the use of non-invasive HF telemonitoring, (2) clarify expectations of telemonitoring among cardiologists and nurses, and (3) describe barriers to the implementation of telemonitoring in Japan and Sweden. Methods This study used a cross-sectional survey of non-invasive HF telemonitoring. A total of 378 Japanese (120 cardiologists, 258 nurses) and 120 Swedish (39 cardiologists, 81 nurses) health care professionals from 165 Japanese and 61 Swedish hospitals/clinics nationwide participated in the study (210 in Japan and 98 in Sweden were approached). Data were collected between November 2013 and May 2014 with a questionnaire that was adapted from a previous Dutch study on telemonitoring. Results The mean age of the cardiologists and nurses was 47 years and 41 years, respectively. Experience at the current position caring for HF patients was 19 years among the physicians and 15 years among the nurses. In total, 7 Japanese (4.2%) and none of the Swedish health care institutions used telemonitoring. One fourth (24.0%, 118/498) of the health care professionals were familiar with the technology (in Japan: 21.6%, 82/378; in Sweden: 30.0%, 36/120). The highest expectations of telemonitoring (rated on a scale from 0-10) were reduced hospitalizations (8.3 in Japan and 7.5 in Sweden), increased patient self-care (7.8 and 7.4), and offering high-quality care (7.8 and 7.0). The major goal for introducing telemonitoring was to monitor physical condition and recognize signs of worsening HF in Japan (94.1%, 352/374) and Sweden (88.7%, 102/115). The following reasons were also high in Sweden: to monitor effects of treatment and adjust it remotely (86.9%, 100/115) and to do remote drug titration (79.1%, 91/115). Just under a quarter of Japanese (22.4%, 85/378) and

    The energy metabolism of essential microbial guilds in the biogeochemical sulfur cycle is based on a DsrAB-type dissimilatory (bi)sulfite reductase that either catalyzes the reduction of sulfite to sulfide during anaerobic respiration of sulfate, sulfite and organosulfonates, or acts in reverse during sulfur oxidation. Common use of dsrAB as a functional marker showed that dsrAB richness in many environments is dominated by novel sequence variants and collectively represents an extensive, largely uncharted sequence assemblage. Here, we established a comprehensive, manually curated dsrAB/DsrAB database and used it to categorize the known dsrAB diversity, reanalyze the evolutionary history of dsrAB and evaluate the coverage of published dsrAB-targeted primers. Based on a DsrAB consensus phylogeny, we introduce an operational classification system for environmental dsrAB sequences that integrates established taxonomic groups with operational taxonomic units (OTUs) at multiple phylogenetic levels, ranging from DsrAB enzyme families that reflect reductive or oxidative DsrAB types of bacterial or archaeal origin, superclusters, uncultured family-level lineages to species-level OTUs. Environmental dsrAB sequences constituted at least 13 stable family-level lineages without any cultivated representatives, suggesting that major taxa of sulfite/sulfate-reducing microorganisms have not yet been identified. Three of these uncultured lineages occur mainly in marine environments, while specific habitat preferences are not evident for members of the other 10 uncultured lineages. In summary, our publically available dsrAB/DsrAB database, the phylogenetic framework, the multilevel classification system and a set of recommended primers provide a necessary foundation for large-scale dsrAB ecology studies with next-generation sequencing methods.

    Ab-initio molecular dynamics study has been performed on face centered cubic structured thorium to determine its melting temperature at room pressure. The ion-electron interaction potential energy calculated as a function of temperature for three volumes (a0)3 and (1.02a0)3 and (1.04a0)3 increases gradually with temperature and undergoes a sharp jump at ~2200 K, ~2100 K and ~1800 K, respectively. Here, a0 = 5.043 Å is the equilibrium lattice parameter at 0 K obtained from ab-initio calculations. These jumps in interaction energy are treated as due to the onset of melting and corresponding temperatures as melting point. The melting point of 2100 K is close to the experimental value of 2023K. Further, the same has been verified by plotting the atomic arrangement evolved at various temperatures and corresponding pair correlation functions.

    The methodology of ab initio molecular dynamics, wherein finite-temperature dynamical trajectories are generated by using forces computed "on the fly" from electronic structure calculations, has had a profound influence in modern theoretical research. Ab initio molecular dynamics allows chemical processes in condensed phases to be studied in an accurate and unbiased manner, leading to new paradigms in the elucidation of microscopic mechanisms, rationalization of experimental data, and testable predictions of new phenomena. The purpose of this work is to give a brief introduction to the technique and to review several important recent developments in the field. Several illustrative examples showing the power of the technique have been chosen. Perspectives on future directions in the field also will be given. PMID:15870204

    We present some recent developments in the ab initio density matrix renormalization group (DMRG) method for quantum chemical problems, in particular our local, quadratic scaling algorithm [1] for low dimensional systems. This method is particularly suited for the description of strong nondynamic correlation, and allows us to compute numerically exact (FCI) correlated energies for large active spaces, up to one order of magnitude larger then can be done by conventional CASCI techniques. Other features of this method are its inherent multireference nature, compactness, variational results, size-consistency and size-extensivity. In addition we will review the problems (predominantly organic electronic materials) on which we applied the ab initio DMRG: 1) metal-insulator transition in hydrogen chains [1] 2) all-trans polyacetylene [1] 3) acenes [2] 4) polydiacetylenes [3].

  10. Understanding phonon transport in thermoelectric materials using ab initio approaches

    Broido, David

    Good thermoelectric materials have low phonon thermal conductivity, kph. Accurate theories to describe kph are important components in developing predictive models of thermoelectric efficiency that can help guide synthesis and measurement efforts. We have developed ab initio approaches to calculate kph, in which phonon modes and phonon scattering rates are computed using interatomic force constants determined from density functional theory, and a full solution of the Boltzmann transport equation for phonons is implemented. A recent approach to calculate interatomic force constants using ab initio molecular dynamics has yielded a good description of the thermal properties of Bi2Te3. But, the complexity of new promising candidate thermoelectric materials introduces computational challenges in assessing their thermal properties. An example is germanane, a germanium based hydrogen-terminated layered semiconductor, which we will discuss in this talk.

    The exact treatment of nuclei starting from the constituent nucleons and the fundamental interactions among them has been a long-standing goal in nuclear physics. In addition to the complex nature of nuclear forces, one faces the quantum-mechanical many-nucleon problem governed by an interplay between bound and continuum states. In recent years, significant progress has been made in ab initio nuclear structure and reaction calculations based on input from QCD employing Hamiltonians constructed within chiral effective field theory. In this contribution, we present one of such promising techniques capable of describing simultaneously both bound and scattering states in light nuclei. By combining the resonating-group method (RGM) with the ab initio no-core shell model (NCSM), we complement a microscopic cluster approach with the use of realistic interactions and a microscopic and consistent description of the clusters. We discuss applications to light nuclei scattering, radiative capture and fusion reactions.

  12. Spin-orbit decomposition of ab initio nuclear wave functions

    Although the modern shell-model picture of atomic nuclei is built from single-particle orbits with good total angular momentum j , leading to j -j coupling, decades ago phenomenological models suggested that a simpler picture for 0 p -shell nuclides can be realized via coupling of the total spin S and total orbital angular momentum L . I revisit this idea with large-basis, no-core shell-model calculations using modern ab initio two-body interactions and dissect the resulting wave functions into their component L - and S -components. Remarkably, there is broad agreement with calculations using the phenomenological Cohen-Kurath forces, despite a gap of nearly 50 years and six orders of magnitude in basis dimensions. I suggest that L -S decomposition may be a useful tool for analyzing ab initio wave functions of light nuclei, for example, in the case of rotational bands.

    Recent progress in the ab-initio molecular dynamics method and the power of parallel computing, allow the detailed study of complex chemical reaction of great industrial relevance. We illustrate this unprecedented capability by investigating the second generation Ziegler-Natta catalytic process. In this inhomogeneous catalyst, a polymerization reaction is induced by TiCl4 molecules deposited on an MgCl2 solid support. A density functional based ab-initio molecular dynamics calculation conducted with a minimum of initial assumption allows to understand the nature of the catalytic center and to determine the reaction path with the associated free energy barrier. Furthermore our calculation can explain in a nontrivial way the stereo-selectivity of the process.

  14. Ab Initio Electronic Relaxation Times and Transport in Noble Metals

    Mustafa, Jamal I.; Bernardi, Marco; Neaton, Jeffrey B.; Louie, Steven G.

    Relaxation times employed to study electron transport in metals are typically assumed to be constants and obtained empirically using the Drude model. Here, we employ ab initio calculations to compute the electron-phonon relaxation times of Cu, Ag, and Au, and find that they vary significantly on the Fermi surface, spanning ~15 -45 fs. We compute room temperature resistivities in excellent agreement with experiment by combining GW bandstructures, Wannier-interpolated band velocities, and ab initio relaxation times. Our calculations are compared to other approximations used for the relaxation times. Additionally, an importance sampling scheme is introduced to speed up the convergence of resistivity and transport calculations by sampling directly points on the Fermi surface.

    Structural and thermal properties of small lithium clusters are studied using ab initio-based Monte Carlo simulations. The ab initio scheme uses a Hartree-Fock/density functional treatment of the electronic structure combined with a jump-walking Monte Carlo sampling of nuclear configurations. Structural forms of Li{sub 8} and Li{sub 9}{sup +} clusters are obtained and their thermal properties analyzed in terms of probability distributions of the cluster potential energy, average potential energy and configurational heat capacity all considered as a function of the cluster temperature. Details of the gradual evolution with temperature of the structural forms sampled are examined. Temperatures characterizing the onset of structural changes and isomer coexistence are identified for both clusters.

  16. Towards AB Initio Calculation of the Circular Dichroism of Peptides

    In this work we plan to use ab initio spectroscopy calculations to compute circular dichroism (CD) spectra of peptides. CD provides information on protein secondary structure content; peptides, instead, remain difficult to address, due to their tendency to adopt multiple conformations in equilibrium. Therefore peptides are an interesting test-case for ab initio calculation of CD spectra. As a first application, we focus on the (83-92) fragment of HIV-1 protease, which is known to be involved in the folding and dimerization of this protein. As a preliminary step, we performed classical molecular dynamics (MD) simulations, in order to obtain a set of representative conformers of the peptide. Then, on some of the obtained conformations, we calculated absorption spectra at the independent particle, RPA and TDLDA levels, showing the presence of charge transfer excitations, and their influence on spectral features.

    We present three girls with the eating disorder anorexia nervosa (AN) presenting with erythema ab igne (EAI), a benign, reticular, erythematous dermatosis caused by repeated prolonged skin exposure to mild heat. AN has been associated with abnormal peripheral vascular response to cold, vasoconstriction of the limbs, low hand blood flow, exaggerated response to cold stimuli, subnormal core temperature, and a general feeling of cold that may encourage prolonged heat exposure and induce EAI.
