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. Method.

This study investigates the importance of implant surface topography on soft tissue response. The tissue response in the rat abdominal wall to discs of low density polyethylene with smooth to coarse surfaces was evaluated after one, six or 12 weeks. Capsule thickness and immunohistochemical quantification of monocytes-macrophages were used as measures. The macrophage specific antibody ED1 was used

Objective: The aim of the present population-based study was to assess the trends of age- and gender-specific incidence of ruptured abdominal aortic aneurysm (rAAA). Methods. Patients with rAAA from the city of Malmo, Sweden, were studied between 2000 and 2004. An analysis of trends of incidence and mortality of rAAA in Malmo was possible because of a previous population-based study on patients wi
