Recent observations by the Goddard High-Resolution Spectrograph on the Rubble Space Telescope have dramatically improved our knowledge of the abundance of the heaviest elements in Mercury-Manganese (HgMn) stars (c.f. Leckrone et al. 1992 and Wahlgren et al. 1995). Explaining the observed abundance and isotope anomalies requires improved calculations of radiatively driven diffusion. We briefly revi
This report highlights the conditions for young people trying to establish themselves in the labour market in the Nordic countries. The aim has been to examine similarities and differences with regard to specific aspects of the welfare systems with a focus on upper secondary school level and political initiatives in the labour market. The passage of students through upper secondary school, transit
Elevated concentrations of inorganic arsenic, one of the most potent environmental toxicants and carcinogens, have been detected in well water around Lake Poopó, Bolivia. This study aimed to assess human exposure to arsenic in villages around Lake Poopó, and also to elucidate whether the metabolism and detoxification of arsenic in this population is as efficient as previously indicated in other An
Sweden succeeded in remaining a non-combatant through the First World War. However, the conflict affected the nation in many ways, for example in terms of film production and film consumption. The Swedish film industry was growing rapidly already before the outbreak of the First World War. The number of cinemas increased every year. It is estimated that there were 700 cinemas in Sweden in 1919, tw
4-Quinolones affect mammalian cellular functions in vitro in several ways. High concentrations inhibit DNA replication, but individual genes are perhaps sensitive to lower concentrations of drug. Inhibition of cell proliferation differs widely among 4-quinolones. Ciprofloxacin and norfloxacin are the most antiproliferative, inhibiting cell growth by -30% at 20 mg/L. Genotoxicity tests with 4-quino
DESIGN:: CCR5-using HIV-1 (R5 viruses) are usually isolated during acute infection from both adults and children. We have recently demonstrated that R5 viruses with a flexible use of CCR5 (called R5broad) can be detected in children close to birth and are predictive of a fast immunological failure. The aim of the present work was to investigate viral phenotype variation during disease progression
OBJECTIVE: The aim of this study was to examine the longitudinal impact of blood pressure variations and vascular risk factors on depressive symptoms in the elderly. DESIGN: Longitudinal and cross-sectional cohort study. SETTING: Urban population of elderly men, city of Malmö, Sweden. PARTICIPANTS: A total of 809 randomly included men took part in a prospective cohort study, "Men born in 1914", an
Infectious diseases remain a major health problem, where sepsis and other severe infectious diseases are common causes of morbidity and mortality. The importance of early and appropriate treatment of sepsis and severe bacterial infections has been underlined by the successes of measures like the Surviving Sepsis Campaign, among others. Thus, there is a need for clinical and laboratory tools to ide
This chapter reviews the experience of one country from the European periphery, Spain, in the period 1960 to 1990. It addresses the possibilities to build up an operative welfare state after recent democratization—past the golden age of economic growth in Western economies, and during the second globalization. The new context made it difficult to develop determined redistributive policies where th
Statistical atmospheric rainfall downscaling, that is, statistical estimation of local or regional rainfall on the basis of large-scale atmospheric circulation, has been advocated to make the output from global and regional climate models more accurate for a particular location or basin. Neural networks (NNs) have been used for such downscaling, but their application has proved problematic, mainly
In previous studies in southern Sweden, early use of oral contraceptives has been found to be accompanied by an increased risk of developing premenopausal breast cancer, and the tumors developing in these patients have shown a more aggressive behavior. In the present study, amplification of the proto-oncogenes Her-2/neu (also known as ERBB2) and INT2 was studied in primary tumor specimens from 72
Protein D, a surface-exposed 42-kDa membrane lipoprotein, is well conserved among both type b and nontypeable Haemophilus influenzae strains, and it is considered a vaccine against H. influenzae infections. Here, we report the large-scale purification of a nonacylated form of protein D (PDm) from the periplasmic space of Escherichia coli overexpressing PDm. Screening of human sera for levels of an
The spatial and temporal pattern of land degradation in northeastern Iceland during the Holocene is analysed in relation to climatic fluctuations. Tephrochronology is used to date the infer-red terrestrial changes. and remote sensing and geographical information systems to assess the dynamic relationships between topographic relief. geomorphic processes and soil structure. Changes in vegetation an
We studied the brittle-ductile transition in three porous carbonates, Indiana, USA, Majella, Italy, and Leitha, Austria, with porosity ranging between 16 and 31%. A series of triaxial experiments were performed at room temperature, constant strain rate, and at effective pressures ranging from 5 to 150 MPa. Several sets of X-ray Tomography images were acquired before and after deformation. 3D digit
Timor-Leste began its independence as one of the poorest nations in the world. Substantial progress has been made thereafter but the challenges for future development are numerous. High population growth and modest growth of GDP means that per capita income is declining and that the extent of poverty is increasing. For this situation to change, income opportunities other than those provided by sub
