This paper reports on a parallel implementation of a general 3D multi-block CFD code. The parallelization is achieved by using three strategies. Firstly, it is done on dual-processor PC-clusters where Windows NT systems are running. A multi-thread programming model is adopted for the multi-block code, where one thread corresponds to a block. Shared-memory is used for the exchange of inner-boundari
Docetaxel-related skin toxicity, oral and gastrointestinal mucosal toxicity, and changes in blood cell counts were investigated as predictive factors for major infections in 143 women treated with 3-weekly docetaxel (100 mg/m(2)) as second-line therapy for metastatic breast cancer in a randomized trial. Each patient with a major infection (n = 37) was compared with two controls. Skin toxicity (odd
Analysis of small-scale movement patterns of animals we may help to understand and predict movement at a larger scale, such as dispersal, which is a key parameter in spatial population dynamics. We have chosen to study the movement of a soil-dwelling Collembola, Protaphorura armata, in an experimental system consisting of a clay surface with or without physical obstacles. A combination of video re
OPENLAND3 belongs to a suite of computer programs included in the POLLSCAPE simulation model. These programs make it possible to calculate estimates of pollen loadings in lake basins or bogs using vegetation data. OPENLAND3, written in Visual Basic 6, is designed to produce appropriate vegetation data files from vegetation maps stored in a Geographical Information System. It calculates percentage
We studied the effect of postoperative radiotherapy (RT) after breast sector resection for ductal carcinoma in situ (DCIS). The study protocol stipulated radical surgery but microscopically clear margins were not mandatory. We randomised 1046 operated women to postoperative RT or control between 1987 and 1999. The primary endpoint was ipsilateral local recurrence. Secondary endpoints were contrala
Context Inpatients with nonvalvular atrial fibrillation, warfarin prevents ischemic stroke, but dose adjustment, coagulation monitoring, and bleeding limit its use. Objective To compare the efficacy of the oral direct thrombin inhibitor ximelagatran with warfarin for prevention of stroke and systemic embolism. Design, Setting, and Participants Double-blind, randomized, multicenter trial (20002001)
Anti-HCV prevalence in treated hemophiliacs, their heterosexual partners, intravenous drug addicts and homosexual men was studied. In hemophiliacs and many of the intravenous drug addicts, greater than or equal to 2 sera drawn 1-18 or 1-17 years apart were available. Anti-HCV testing was performed by ELISA (Ortho). Among patients with severe and moderate hemophilia A, 87% (98/112) were positive fo
Ett antal försök på olika typer av sandwichpaneler har genomförts. De valda sandwichpanelerna inkluderar de vanligaste kärnmaterialen. Två olika fullskaletester har genomförts. En av dem var utförd enligt ISO 9705 d.v.s. försök där panelerna var monterade inuti ett obrännbart rum. Det andra sättet av fullskaletesten var utförd genom att använda ett fristående rum under en stor kalorimeter. Denna kSummary : A number of tests have been performed on different types of sandwich panels. The chosen sandwich panels included most common core materials. Two types of full-scale tests were performed. One set was conducted according to ISO 9705 i.e. tests where the panels were mounted inside a non-combustible room. Another set of full-scale tests was performed using a free standing room under a large
By putting emphasis on applications in two basic statistics courses for chemistry students and chemical engineering students we have enhanced student motivation and increased student activity. In addition to a traditional in-class exam, the students complete a take-home project where statistical problems relevant to chemists are discussed. We give several examples of the course and project materia
An approach to teaching calorimetry is offered through practical, versatile undergraduate experiments using an isothermal heat conduction calorimeter, which measures a variety of heat changes--enthalpies of phase changes, hydration, dissolution, adsorption and desorption, and reaction--as well as the metabolic rate of living organisms. Isothermal heat-conduction calorimetry is contrasted with adia
Today, driver support tools intended to increase traffic safety, provide the driver with convenient information and guidance, or save time are becoming more common. However, few systems have the primary aim of reducing the environmental effects of driving. The aim of this project was to estimate the potential for reducing fuel consumption and thus the emission of CO, through a navigation system wh
Agriculture in many African countries is characterised by large diversity in production and great variation in growing conditions, irrigation potential and access to markets. This variation has proved to be a difficult matter when adjusting national agricultural policies and development projects to local conditions. In the face of the recent trend of less support for agricultural extension servic
PURPOSE: Mutations in the NDP gene give rise to a variety of eye diseases, including classic Norrie disease (ND), X-linked exudative vitreoretinopathy (EVRX), retinal telangiectasis (Coats disease), and advanced retinopathy of prematurity (ROP). The gene product is a cystine-knot-containing extracellular signaling molecule of unknown function. In the current study, gene expression was determined i
Aims: The increasing number of people on disability pension in Sweden is of concern for Swedish policy-makers, and there is a need for a better understanding of the mechanisms behind disability pension. We investigated ( i) whether women living in the same neighborhood have a similar propensity for disability pension that relates to neighborhood social participation, and ( ii) whether there is an
Wastewater treatment plant operators encounter complex operational problems related to the activated sludge process and usually respond to these by applying their own intuition and by taking advantage of what they have learnt from past experiences of similar problems. However, previous process experiences are not easy to integrate in numerical control, and new tools must be developed to enable re-
Maturity-onset diabetes of the young (MODY) is a heterogeneous single gene disorder characterized by non–insulin-dependent diabetes, an early onset and autosomal dominant inheritance. Mutations in six genes have been shown to cause MODY. Approximately 15–20% of families fitting MODY criteria do not have mutations in any of the known genes. These families provide a rich resource for the identificat
This article examines continuity, change and adaptation of blat, a Soviet-time informal economic transaction network, in today’s Ukraine and Belarus. The analysis is based on 33 in-depth interviews, and the main focus is the descriptions, justifications and explanations of on-going informal participation in contemporary forms of blat. Theories on informal institutions, path dependence and the rela
