Based on detailed 2D and 3D numerical radiation hydrodynamicscalculations of time-dependent compressible convection, we have studiedthe dynamics and thermal structure of the convective surface layers of aprototypical late-type M-dwarf at Teff=2800 K, and log g=5.0with solar chemical composition. The thermal structure of the atmosphereis dominated by molecular absorption, the formation o
The heavy recession in Sweden during the first half of the nineties led to a very difficult situation for young people with a weak position on the labour market. Around a third of the youths born in the mid seventies had received social welfare benefits before the age of 24. Despite the recovery in the Swedish economy a group of young adults, now in their thirties, simply can not find a way to eit
Popular Abstract in Swedish Universitet och högskolor har i kölvattnet av ett framväxande kunskapssamhället hamnat under kraftig institutionell press från en förändrad nationell forskningspolitik, de forskningsfinansierande aktörernas förändrade strategier och en snabb och omvälvande vetenskaplig dynamik. Avhandlingen handlar om hur Lunds universitet har reagerat på och hanterat dessa förändringspIn the wake of an emerging knowledge society, universities around the world have come under severe institutional pressure from changing national research policies, financing organizations´ new strategies and turbulent research dynamics. This study examines how Lund University in Sweden manages these institutional pressures. The study explores how the university leadership ? rector and the governin
The UV-dissipative mechanisms of the eumelanin building block 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and the 4,7-dideutero derivative (DHICA-d(2)) in buffered H(2)O or D(2)O have been characterized by using ultrafast time-resolved fluorescence spectroscopy. Excitation of the carboxylate anion form, the dominating state at neutral pH, leads to dual fluorescence. The band peaking at lambda=37
The aim of this study was to describe some of the factors that might play a role in influencing attitude to xenotransplantation: first, the consideration of receiving cells and tissue from xenotransplants in relation to whole xeno-organs; secondly, the fact that there is greater uncertainty regarding the result and risk of infection associated with xenotransplantation than with allotransplantation
The Na-33 beta decay was studied online using mass separation techniques and a first description of the level structure of the neutron-rich isotope Mg-33, with N=21, has been obtained. The experiment involved the measurement of beta-gamma, beta-gamma-gamma, and beta -n-gamma coincidences as well as neutron spectra by time-of-flight technique. The first low energy level scheme for the daughter nucl
Popular Abstract in Swedish Den dansk-svenske forfatter Gustaf Munch-Petersen (1912-1938) betragtes som en af portalskikkelserne i den danske lyriske modernisme. Han døde 26 år gammel som frivillig i den spanske borgerkrig, en konflikt, vi i dag ofte betragter som en del af optakten til anden verdenskrig. Dette tidlige endeligt gjorde ham til en af skandinavisk litteraturs ”unge døde”. Men det er
To evaluate the expression and protein levels of antioxidant enzymes in the rat retina exposed to oxidative stress induced by ischemia-reperfusion injury. Retinal ischemia was induced in female Wistar rats by ligation of the optic nerve and vessels behind the left eye bulb, and was followed by reperfusion for 0, 3, 6, or 24 hours. The right eye served as control. RNA and protein were extracted sim
An analysis of inelastic photoproduction of J/psi mesons is presented using data collected at the ep collider HERA corresponding to an integrated luminosity of above 80 pb(-1), Differential and double I < P-t/psi(2) < differential cross sections are measured in a wide kinematic region: 60 < W-gammap < 260 GeV, 1 p(t,psi)(2) < 60 GeV2 and 0.05 < z < 0.9. where z is the fraction of the energy of the
The decreased survival of von Willebrand factor (VWF) in plasma has been implicated as a mechanism in a subset of type 1 von Willebrand disease (VWD) patients. We have previously reported that the ratio of plasma levels of VWF and its propeptide (VWFpp) can be used to identify patients with reduced VWF survival. In this study, we report the assay of VWFpp and VWF:Ag in 19 individuals recruited fro
The electroenzymatic reactions of Trametes hirsuta laccase in the pure organic solvent dimethyl sulfoxide (DMSO) have been investigated within the framework for potential use as a catalytic reaction scheme for oxygen reduction. The bioelectrochemical characteristics of laccase were investigated in two different ways: (i) by studying the electroreduction of oxygen in anhydrous DMSO via a direct ele
The expression of genes specifically in B cells is of great interest in both experimental immunology as well as in future clinical gene therapy. We have constructed a novel enhanced B cell-specific promoter (Igk- E) consisting of an immunoglobulin kappa (Igk) minimal promoter combined with an intronic enhancer sequence and a 30 enhancer sequence from Ig genes. The Igk- E promoter was cloned into a
A succession of 26 conodont zones and 63 successive subzones and conodont faunas have been identified in the exposed latest Landovery to latest Ludlow strata of Gotland, Sweden. All zones, and several of the subzones and faunas, have been identified elsewhere on Baltica as well as on other palaeocontinents, indicating that this zonation serves well as the standard zonation for calcareous successio
The thorough experimental characterization of a dowel-type connection under various combinations of bending moments and normal forces is presented in this study. Double-shear steel-to-timber connections with 12 and 20 mm steel dowels were tested in a 4-point bending test set-up. The load, between the connected steel and wood beams, was transferred by the dowels themselves and also via an additiona
Based on an ethnographic survey of the 26th Conference of the United Nations Framework Convention on Climate Change, this article analyses the ways in which youth participate in climate negotiations. We show how youth actors are characterised by diverse modes of engagement, and particular sociodemographic anchors. Presenting themselves as the voice of youth worldwide, youth actors have gradually c
Dynamic capabilities enable firms to systematically modify their resource base and build competitive advantage. As dynamic capabilities literature is diverging in definition and scope, this research work analyzes conceptual literature on dynamic capabilities regarding commonalities, differences, and development over time. Therefore, a total of 56 publications in eleven highly ranked journals betwe
With increasing concerns about environmental impacts of the food that is consumed, so is also the concern about packaging materials. This also comprises the packaging that is currently used to pack infant formula (IF), very often containing aluminum as the barrier material. IF is a very sensitive product that demands for the highest barriers to protect it from lipid oxidation. This implies that th
