Mechanical load through physical activity has been shown to be one of the best stimuli to increase the bone strength. This effect of mechanical load accounts for both the accrual of bone mineral and structural skeletal adaptations. Exercise prescription also includes a "window of opportunity" in the late pre- and early peri-pubertal period, where exercise is supposed to insert the most obvious ben

Genom EU-rätten och Sveriges konventioner om social trygghet ingår Försäkringskassan och andra svenska socialförsäkringsorgan i internationella administrativa samarbetsstrukturer. I dessa utbyts uppgifter om enskilda i fråga om exempelvis namn, familjeförhållanden och hälsotillstånd. I artikeln undersöks hur Försäkringskassan ska delta i sådant informationsutbyte och samtidigt tillämpa den svenska

A matched case-referent study was conducted to investigate the risk of gastrointestinal cancer in cement workers. All male cases of cancer in esophagus, stomach, colon and rectum in the period 1922-1988 from two parishes surrounding a cement plant were identified. For each case, four referents were chosen, matched to age and year of death. Employment in the cement plant was confirmed as from plant

Limited data exist on surgical providers and their scope of practice in low-income countries (LICs). The aim of this study was to assess the distribution and productivity of all surgical providers in an LIC, and to evaluate correlations between the surgical workforce availability, productivity, rates, and volume of surgery at the district and hospital levels.

Popular Abstract in Swedish Utveckling av nya industriella produkter sker allt oftare med hjälp av datormodeller. Dessa modeller beskriver fysiken för respektive produkt, vilket exempelvis kan vara en bil eller ett kraftverk. Med hjälp av modellerna kan en stor del av analyserna på de framtida produkterna ske med hjälp av datorer, varför färre prototyper behöver konstrueras, vilket medför kortare Simulation of coupled dynamical systems, where the subsystems are bundled with their own internal solver, is important in industry. This is due to that in many cases, with complex systems, this is the only viable option. In this setting, the dynamics of each system is hidden and information between subsystems is exchanged through sampled inputs and outputs, a weakly coupled system. While a new ind

The issue of word stress has not been the subject of any detailed analysis in traditional works on Romanian. It is generally assumed that stress is not predictable. The generalizations that have been made concerning stress placement are, however, made on the basis of observations of surface forms. Mallinson 1987:300 says that “stress is free and variable, giving rise to doublets: m'odele ‘the fash

BACKGROUND: Refugee women have a high risk of coronary heart disease with low physical activity as one possible mediator. Furthermore, cultural and environmental barriers to increasing physical activity have been demonstrated. The aim of the study was to evaluate the combined effect of an approximate 6-month primary health care- and community-based exercise intervention versus an individual writte

The pancreatic islet beta-cells are the target for an autoimmune process that eventually results in an inability to control blood glucose due to the lack of insulin. The different steps that eventually lead to the complete loss of the beta-cells are reviewed to include the very first step of a triggering event that initiates the development of beta-cell autoimmunity to the last step of appearance

A new method for QRST cancellation is presented for the analysis of atrial fibrillation in the surface electrocardiogram (ECG). The method is based on a spatiotemporal signal model which accounts for dynamic changes in QRS morphology caused, e.g., by variations in the electrical axis of the heart. Using simulated atrial fibrillation signals added to normal ECGs, the results show that the spatiotem

The purpose of the current study is to investigate the effect of particle-pair interaction for various separation distances and angular positions. The results obtained are used in a particle-laden turbulent jet flows in order to improve the existing Lagrangian Particle Tracking (LPT) models. In the first part, a detailed numerical study of particle interaction is carried out by varying the separa

This environmental audit report was completed after an environmental audit of the Baltijsk municipality in the District of Kaliningrad, Russia, during the 10th and 11th of April 2000. The report is a joint effort of 31 students from 23 countries, who are participants of the International Master’s Programme “Master of Science in Environmental Management and Policy ” at the International Institute

För att nå energimålen för bebyggelsen till 2020, uppsatta av EU och av den svenska regeringen, är det nödvändigt att inte bara minska energianvändningen i nybyggnader utan att även energieffektivisera befintlig bebyggelse. När renovering ändå genomförs finns stora möjligheter att utföra energibesparande åtgärder och på samma gång höja inomhuskomforten för de boende.
