Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. The first type was developed to be a part of the tracking system of the WA98 experiment. The tracking chambers were designed to provide

Sodium stearoyl-2 lactylate (SSL) lipid surfactant molecules specifically bind partially hydrolysed oat proteins in aqueous medium and significantly enhance the dispersion stability of oat cereal preparations. The proposed complexation is composition dependent and a greater understanding of the role of both oat proteins and lipid surfactant in the effect was gained with data from high performance

This book, which is the result of my work within the project Conversion and Change of Confession, deals with Catholic mission and conversion in Scandinavia in the 19th and 20th cetries. I focus on Denmark, but the Danish situation is studied in a comparative Nordic pespective and against the background of the general religious, ideological and church-political development at the time. Up to the Se

The study aimed to elucidate the effects of cortical ischemia and postischemic environmental enrichment on hippocampal cell genesis. A cortical infarct was induced by it permanent ligation of the middle cerebral artery distal to the striatal branches in 6-month-old spontaneously hypertensive rats. Bromodeoxyuridine (BrdU) was administered as 7 consecutive daily injections starting 24 hours after s

When developing packaged software, which is sold `off-the-shelf' on a worldwide marketplace, it is essential to collect needs and opportunities from different market segments and use this information in the prioritisation of requirements for the next software release. The paper presents an industrial case study where a distributed prioritisation process is proposed, observed and evaluated. The sta

A class of spherical functions is studied which can be viewed as the matrix generalization of Bessel functions. We derive a recursive structure for these functions. We show that they are only special cases of more general radial functions which also have a properly generalized, recursive structure. Some explicit results are worked out. For the first time, we identify a subclass of such radial func

In male birds, testosterone (T) plays an important role in aggressive and mate-attraction behaviour. In the cooperatively breeding Seychelles warbler, Acrocephalus sechellensis, extra-group copulations (EGCs) occur frequently, but are not accompanied by sexual courtship displays as in within-pair copulations. Paternity is nearly always gained by primary males. We investigated whether T levels and

Popular Abstract in Swedish Streptokocker orsakar flera olika infektioner hos människa såsom halsfluss, svinkoppor och sällsynta livshotande sjukdomstillstånd som blodförgiftning, toxiskt chock syndrom, nekrotiserande fasciit, glomerulonefrit, och reumatisk feber. För att orsaka dessa infektioner måste bakterierna undvika immun-försvaret. Komplementsystemet utgör en viktig del av det medfödda immuStreptococcus pyogenes is a common human pathogen, which causes a variety of diseases. A major virulence factor of S. pyogenes is the surface-associated M protein, which mediates resistance to phagocytosis. Several studies indicate that M proteins inhibit complement deposition and thereby phagocytosis. It is often assumed that S. pyogenes lacking M protein activates complement via the alternative

Immunoreactive insulin was measured in acid-ethanol extracts of kidney, brain, liver, and heart from genetically diabetic Chinese hamsters and their nondiabetic controls and from obese (ob/ob) mice and their thin littermates. Selected samples were filtered on Sephadex G-50 columns and the insulin concentration determined. There was a good correlation between the insulin level measured in the acid-

This thesis deals with a recent event within the history of religions, the rise and development of a non-Christian prophetic movement named Kiyang-yang within the oral, kinship and ancestor based society of the Balanta in Guinea-Bissau. Kiyang-yang is headed by young women and men under the leadership of a woman prophet. The movement aims at a global and radical change of the existing Balanta way

Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland, central Sweden, and the Middle Ordovician Killeröd Formation in Skåne (Scania), southern Sweden, are revised and discussed. These formations have several genera and a few species in common, e.g. Botrioides efflorescens (Hadding, 1913a) and Pseudomegalaspis patagiata (Törnquist, 1884). The regional and vertical di

ABSTRACT: BACKGROUND: Topical negative pressure (TNP), commonly used in wound therapy, has been shown to increase blood flow and stimulate angiogenesis in skeletal muscle. We have previously shown that a myocardial TNP of -50 mmHg significantly increases microvascular blood flow in the myocardium. When TPN is used in wound therapy (on skeletal and subcutaneous tissue) a zone of relative hypoperfus

Background Despite high incidence of ankle fractures in the elderly, studies evaluating outcome and impact of quality of life in this age group specifically are sparse. The aim of this study was to evaluate outcome and quality of life 6 and 12 months after injury in patients 65 years or older who had been operated on due to an ankle fracture. Methods Sixty patients 65 years or older were invited

Two-pulse photon-echo measurements on the 0.1 at. % Pr3+:YAlO3 H-3(4)-D-1(2) transition suggest that the relaxation time depends on the density of excited states created by the excitation pulses. The dependence of the relaxation time on the intensity of each excitation pulse shows that our results are inconsistent with instantaneous spectral diffusion, a model often invoked in this type of experim

Embryonic stein (ES) cells are derived from the inner cell mass of the blastocyst and can be cultured as three-dimensional embryoid bodies (EBs) in which embryonic pregastrulation stages are faithfully mimicked. Fibroblast growth factor receptors (mainly FGFR2) are involved in the first differentiation events during early mammalian embryogenesis. It has been demonstrated that the presence of FGFR2
