In this paper, a high-resolution finite volume method for calculating solutions to a hyperbolic conservation law is presented. The method works in two space dimensions on general domains and uses curvilinear meshes. A non-trivial estimation of gradients needed for the reconstructions is presented. The paper contains examples of numerical solutions of the Enter gas dynamics equations.

Aim. This paper reports a study investigating quality of life in relation to loneliness, caregiving, social network, gender, age and economic status among caregiving men and women in a population-based sample aged 75 years or older.Background. Because of demographic changes, in the future more care for older people will be given by informal caregivers who are themselves older. Being old and caring

BACKGROUND: Glutathione transferases (GST) are a group of multifunctional enzymes important in the detoxification of many electrophiles and, in addition, fatty acid hydroperoxides, thus limiting tissue damage from oxidative free radical attack. Of the four classes of GST (alpha, mu, pi, and theta), a class mu isoenzyme, GST mu, is dominantly inherited and is expressed in approximately half of the

The dynamic forest ecosystem model ForSAFE was applied at 16 coniferous forest sites in Sweden to investigate past and future changes in soil chemistry following changes in atmospheric deposition. The simulation shows a considerable historical soil acidification. Acidification in the southwest, where deposition has been greatest, was more expressed in the deepest soil layers, while it was more eve

OBJECTIVE: Endoleaks and endotension are critically important complications of some endovascular aortic aneurysm repairs (EVARs). For the resolution of controversial issues and the determination of areas of uncertainty relating to these complications, a conference of 27 interested leaders was held on November 20, 2000. METHODS: These 27 participants (21 vascular surgeons, five interventional radio

Modern societies' functionality is strongly dependent on the electricity. Efficient, environment friendly, and economical power production has been in focus for a long time. The introduction of computers and thereby computer-aided tools for pre-design studies, optimization and choice of the best operational strategies, has changed the conditions for power production tremendously. The most noticeab

1. We and others have shown that extracellular ATP (adenosine triphosphate), released from sympathetic nerves and platelets, stimulates growth of vascular smooth muscle cells (SMC). To study the importance of tyrosine kinases for ATP-mediated proliferation in vascular smooth muscle cells we used tyrphostins, a recently developed group of highly specific inhibitors of tyrosine kinases. 2. ATP induc

High-spin states in Cu-59 were populated using the fusion-evaporation reaction Si-28 + Ca-40 at a beam energy of 122 MeV. The Gammasphere Ge-detector array in conjunction with the 4pi charged-particle detector array Microball allowed for the detection of gamma-rays in coincidence with evaporated light particles. The resulting extensive high-spin decay scheme of Cu-59 is presented, which comprises

The basic helix–loop–helix proteins form a special group of transcription factors unique for the eukaryotic organisms. They are crucial for the embryonic development of many fundamental organ systems such as muscle, heart, central nervous system, hematopoiteic system, and many others. They are very flexible in terms of regulating transcription in that they can either promote or repress transcripti

It is proved that existence of a density function is both necessary and sufficient for almost global stability in a nonlinear system.

I rapporten redogörs för ett fältförsök med renovering av krypgrundläggning för småhus. För detta ändamål studerades sju likadana hus i samma kvarter under tre år. Fem hus försågs med markisolering i efterhand efter det att underkanten på bjälklaget i krypgrunden hade behandlats med borsyra. En annan förberedande åtgärd var att byta ut en på marken befintlig byggplastfolie mot fiberduk. Ett hus ha

The aim of the study was to determine students' self-rated health in relation to sense of coherence and other personality traits. A cross-sectional descriptive design was used with questionnaires as the means of data collection. The study population comprised a randomized stratified sample of students from a small university in southern Sweden. Ethical approval was obtained from the vice chancello

Objective. Lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) are a common condition in men, and their incidence increases with age. The objective of this study was to evaluate the potential cost-utility of microwave thermotherapy, specifically the ProstaLund Feedback Treatment (PLFT), versus alpha-blockade in Swedish patients with LUTS due to BPH. Material and methods.
