Early Ordovician (Late Arenig) limestones from the SW margin of Baltica (Scania-Bomholm) have multicomponent magnetic signatures, but high unblocking components predating folding, and the corresponding palaeomagnetic pole (latitude = 19degreesN, longitude = 051degreesE) compares well with Arenig reference poles from Baltica. Collectively, the Arenig poles demonstrate a midsoutherly latitudinal pos

Whereas uncoupling protein 1 (UCP-1) is clearly involved in thermogenesis, the role of UCP-2 is less clear. Using hybridization, cloning techniques and cDNA array analysis to identify inducible neuroprotective genes, we found that neuronal survival correlates with increased expression of Ucp2. In mice overexpressing human UCP-2, brain damage was diminished after experimental stroke and traumatic b

Popular Abstract in Swedish Utformningen av fattigvården och de arbetskrav man ställer på mottagarna har alltid varit kontroversiella frågor i socialpolitiken, såväl under fattig- och arbetshusens tidsålder under 1800-talet, som i nuvarande diskussioner om socialbidrag och aktivering av bidragstagarna. Den första delen av avhandlingen diskuterar begreppen fattigdom, marginalisering och social utesManagement of poor relief and work demands have been controversial questions in social policy during the workhouse era of the nineteenth century as well as in current discussions on social assistance and activation of recipients. The first part contains a discussion on the concepts of poverty, marginalisation, and social exclusion, and continues with an overview of activation policies for recipien

Transforming growth factor beta (TGF-beta) is a potent inhibitor of hepatocyte proliferation in vitro and is suggested to be a key negative regulator of liver growth. To directly address the role of TGF-beta signaling in liver regeneration in vivo, the TGF-beta type II receptor gene (Tgfbr2) was selectively deleted in hepatocytes by crossing "floxed" Tgfbr2 conditional knockout mice with transgeni

Overheating is a paramount problem in residential buildings in hot-humid climates in China during summer. This study aims to deal with the overheating problem and the problem of poor air quality in dwellings. The main objective is to improve indoor thermal conditions by passive cooling approaches, climatisation techniques in buildings without auxiliary cooling from air conditioning equipment. A f

Syftet med projektet är att teoretiskt utreda två frågeställningar med direktlimmat trägolv på betongunderlag. Första frågeställningen är i vilka fall det behövs ett extra fuktskydd under trägolv från AB Gustaf Kährs, för att undvika skador orsakade av byggfukt i underlag av normal husbyggnadsbetong. Andra frågeställningen är vilken ekvivalent uttorkningstid som behövs för byggfuktfri betong innan

Popular Abstract in Swedish Ett centralt problem inom området datorseende är att utifrån bara ett antal bilder av föremål, återskapa formen av föremålet som avbildats. Samtidigt vill man även återskapa hur kameran rört sig mellan de olika bilderna tagits. Detta är det så kallade struktur och rörelse-problemet. I avhandlingen löses detta problem för olika typer av kameror samt olika typer av objektThis thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. Much of the thesis is centred on the problem of finding initial estimates of the structure and the motion using a small set of image data. These initial estimate

An aqueous two-phase system based on the two polymers poly(ethylene glycol) and dextran has been used for the fractionation of cellulase enzymes present in culture liquid obtained by fermentation with Trichoderma reesei. The activities of beta-glucosidase and glucanases were separated to high degree by using the two-phase systems for a counter-current distribution process in nine transfer steps. W

Popular Abstract in Swedish Denna studie betonar att de mekanismer, som skapar tillväxt, inte nödvändigtvis är universella utan kan skilja sig åt mellan olika områden, beroende på vad som produceras och vilken teknik som används. Avhandlingen hävdar inledningsvis att ekonomisk tillväxt är den viktigaste enskilda faktor som påverkar individers inkomstnivå och att ökad produktivitet i sin tur är gruThis study shows that the mechanisms behind knowledge accumulation and the sources of productivity growth differ from industry to industry depending on what is produced and what technology is used. Although it is apparent to most researchers in the field that the only way to explain long-run growth in output per capita is through technological progress and accumulation of knowledge that counteract

Responses to isotonic quick releases of rabbit urinary bladder strips and rat portal veins activated by AC-stimulation and K+-high medium were studied. The AC stimulation was adjusted to give the same tension as th K+-contractures. Releases were performed at peak of the contractions (which was attained after 1.5-4.5 s AC-stimulation or 2-3 min in K+-high solution). The length response consisted of

Intracellular lipid-binding proteins contain a large binding cavity filled with water molecules. The role played by these water molecules in ligand binding is not well understood, but their energetic and dynamic properties must be important for protein function. Here, we use the magnetic relaxation dispersion (MRD) of the water 17O resonance to investigate the water molecules in the binding cavity

An automated high-performance liquid chromatographic (HPLC) method has been developed for measurement of 5-S-cysteinyl-DOPA in urine (DOPA = 3,4-dihydroxyphenylalanine). The urinary sample was injected into an HPLC boronate column. With a mobile phase of 0.1 M phosphate buffer containing 0.2 mM disodium ethylenediaminetetraacetate (Na2EDTA) (pH 6.0) mixed with methanol (9:1), 5-S-cysteinyl-DOPA wa
