CFD simulation and experimental tests have been carried out to study the room corner fire growth on combustible wall-lining materials. In the CFD simulation, the turbulent mass and heat transfer, and combustion were considered. The discrete transfer (DT) method was employed to calculate the radiation with an absorptivity and emissivity model employed to predict the radiation property of combustion
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
Monitoring of events in the power system provides a great deal of insight into the behavior of the system. Events with impact on the entire power system typically occur in or near the transmission network and are therefore best monitored at transmission system substations. This puts great demands on the equipment and in general restricts the use of the data since it becomes property of the transmi
This article has a threefold purpose. First, it seeks to show how modern rituals among Mi'kmaq traditionalists in eastern Canada are anchored in and derive their rationale from modern reserve existence. Two rituals are described, a kekunit godparent ceremony for a 14-year-old girl and a sweat lodge ceremony later the same evening. Second, the article also provides an example of the paradoxes of "p
OBJECTIVE: To monitor changes in family physicians' reported practice on hypertension and hypercholesterolaemia. DESIGN: Random samples of physicians were selected for telephone interviews on their practice regarding cut-off levels and pharmacological treatment of hypertension and hypercholesterolaemia, related to a case scenario of a 48-year-old man, in 1989, 1991 and 1993. SETTING: Primary care
Animal models of neurological deficits are essential for the assessment of new therapeutic options. It has been suggested that rats are not as appropriate as primates for the symptomatic modelling of disease, but a large body of data argues against this view. Comparative analyses of movements in rats and primates show homology of many motor patterns across species. Advances have been made in ident
A new predictive formula for the total longshore sediment transport (LST) rate was developed from principles of sediment transport physics assuming that breaking waves mobilize the sediment, which is subsequently moved by a mean current. Six high-quality data sets on hydrodynamics and sediment transport collected during both field and laboratory conditions were employed to evaluate the predictive
We obtain a relation between the time between two bird-catchings and the total resting period of a bird, leading to the problem of estimating the derivative of a convex density. We state a fundamental result on the nonparametric maximum likelihood estimator of a convex density. Further, we derive the optimal rate in the minimax risk sense for estimating the derivative of a convex density.
In this paper, return migration from Sweden to three sources of refugee immigration is analysed, with a focus on the effect of political change in 1990. Chilean immigrants reacted more strongly to political liberalization in the home country than Polish immigrants did, primarily due to more favourable economic circumstances in Chile compared to Poland in the 1990s. In fact, the increase in Polish
Expression of the human cysteine proteinase inhibitor, cystatin C (CysC) in the cytoplasm of Escherichia coli was studied using a cDNA fragment encoding the cysteine proteinase inhibitor controlled by the phage λ pImage /cI857 system. The yield of CysC was low, probably due to proteolytic degradation. By fusing the cysC cDNA to a DNA fragment encoding the signal peptide of the E. coli outer membra
PURPOSE: The reduced size of abdominal aortic aneurysms (AAAs) after endovascular repair suggests lowered intraaneurysmal pressure. In the presence of endoleaks, the size is not decreased. Although postoperative intraaneurysmal pressure is difficult to record, the pulsatile wall motion (PWM) of aneurysms can be measured noninvasively. The aim of this study was to assess the PWM of AAAs before and
