The following presentation specifies the thermal characteristics of the compartment fire exposure and the standard fire exposure as a basis for an analytical fire design of load bearing structures, particularly steel structures. The connection between the two types of exposure is dealt with according to the concept of equivalent time of fire exposure. given in an approximate as well as in a more a
Background The purposes of this study were (1) to evaluate the wear pattern of the hydroxyapatite-coated "Dual Radius" Omnifit cup, (2) to investigate whether wear is correlated to any demographic or prosthesis-related factors, and (3) to describe micromotion of both the cup and the stem. Patients and methods 154 hips were implanted between 1990 and 1996 and followed for an average of 6 years. Wea
The effects of hypothermia on hypoglycemic brain damage were studied in rats after a 30-min period of hypoglycemic coma, defined as cessation of spontaneous EEG activity. The rats were either normothermic (37 degrees C) or moderately hypothermic (33 degrees C). Morphological brain damage was evaluated after various periods of recovery. Hypothermic animals with halothane anesthesia never resumed sp
Objective: The hemodynamic effects of vacuum-assisted closure therapy in cardiac surgery are debated. The aim of the present study was to quantify cardiac output and left ventricular chamber volumes after vacuum-assisted closure using magnetic resonance imaging, which is known to be the most accurate method for quantifying these measures. Methods: Six pigs had median sternotomy followed by vacuum-
Avhandlingen tar som utgångspunkt diofantisk approximation med fokus på dåligt approximerbara tal. För specialfallet de q-adiska rationella talen betraktar vi två typer av approximationsmodeller, en ensidig och en tvåsidig modell, och de dåligt approximerbara tal de ger upphov till. Vi visar med elementära metoder att Hausdorff-dimensionen av dessa två mängder beror kontinuerligt på en definierandThe thesis takes as starting point diophantine approximation with focus on the area of badly approximable numbers. For the special kind of rationals, the q-adic rationals, we consider two types of approimations models, a one-sided and a two-sided model, and the sets of badly approximable numbers they give rise to. We prove with elementary methods that the Hausdorff dimension of these two sets depe
This paper describes the sedimentology, morphology and diagenesis of recently discovered Middle Silurian low-relief micro-epikarst from the Klintehamn area on western Gotland (Sweden). The epikarst represents the most distal portion of an unconformity that truncates stratigraphic units across a major part of the Baltic palaeo-basin. It formed in the intertidal area during the late stage of platfor
A series of intramolecular condensation products were obtained by base-catalyzed treatment of the natural bioactive dimeric phthalide diligustilide (1) using different reaction conditions and the yields remarkably depend on these. The reaction conditions to obtain selectively the intramolecular condensation derivatives or the hydrolysis products of diligustilide (1) are described.
A method for simultaneous determination of 5-hydroxy-N-methyl-2-pyrrolidone (5-HNMP) and 2-hydroxy-N-methylsuccinimide (2-HMSI) was developed. These compounds are metabolites from N-methyl-2-pyrrolidone (NMP), a powerful and widely used organic solvent. 5-HNMP and 2-HMSI were purified from plasma and urine by solid-phase extraction using Isolute ENV+ columns, and analysed by liquid chromatography
Inom en snar framtid kommer många havsbaserade vindkraftverk troligen att byggas runt om Sveriges kuster. Det bör finnas ett behov av gemensamma regler eller tekniska lösningar inför en sådan byggnation så att vindkraftverken som helhet får en avsedd livslängd och små underhållskostnader.
Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA (Swedish summary) Ultraljud används sedan 1970-talet rutinmässigt under graviditet. Undersökningen görs vanligen vid 17-18 graviditetsveckor och syftet med undersökningen är att datera graviditeten dvs bestämma tiden för beräknad förlossning. Man upptäcker också eventuella tvillingar vid denna undersökning. Redan tidigt visade det sig att visWe studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. We studied the effect of prenatal diagnosis on the rate of spina bifida in southern Sweden compared with the rest of the country and could show tha

Determination of D-arabinitol/L-arabinitol ratios (referred to as D/L-arabinitol ratios) in urine as a tool for the diagnosis of invasive candidiasis was investigated in a prospective study comprising 100 children with cancer. The analyses were made by gas chromatography. Positive D/L-arabinitol ratios were found for 10 of 10 children with confirmed invasive candidiasis, 12 of 23 patients undergoi
Abstract in French Description. Afin d'orienter les recherches futures dans les domaines des aides techniques et des questions liées à l'environnement physique, il est important de bien comprendre les études menées précédemment. But. Cette recension des écrits avait pour but de déterminer la manière selon laquelle les aides techniques et les questions touchant l'environnement physique ont été étudBackground. To determine future directions for research in the area of assistive technology and physical environmental issues, it is important to have an understanding of prior research. Purpose. This literature review examined how assistive technology and physical environmental issues have been studied in the research published in international peer-reviewed occupational therapy journals.
