Popular Abstract in Swedish Om flyttningens betydelse för utbredningsmönster för arktiska fåglar Sara Henningsson Fågelflyttning är en anmärkningsvärt framgångsrik strategi som möjliggör att en större mängd individer kan försörjas genom rörelser mellan olika regioner. Inom dessa olika områden, som ofta ligger mycket långt ifrån varandra, kan fåglarna utnyttja stora säsongsmässigt tillgängliga resFlexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. I studied the circu

This thesis is divided into two parts in which two different aspects of the Large Hadron Collider (LHC) Project are discussed. The first part describes the design of a transition radiation tracker (TRT) for the inner detector in ATLAS. In particular, the barrel part was studied in detail. The barrel TRT consists of 52 544 1.5-m-long proportional tubes (straws), parallel to the beam axis and each

Proton exchange membrane fuel cell (PEMFC) systems have been investigated as alternative power sources for the stationary and automotive applications. However, they do not appear on the market yet. One of the main reasons is the difficulty of the water/thermal management in the system. Several water recovery schemes have been proposed to overcome this difficulty and to simplify the system configur

Popular Abstract in English Candida glabrata is currently the second most usual cause of yeast infections. This yeast is phylogenetically more related to Saccharomyces cerevisiae than to Candida albicans. Many systemic infections have recently been found associated with C. glabrata yeast. Apparently, this yeast can easily reshuffle its genome and this is one of the topics of my thesis. During the Although the yeast Candida glabrata is considered to be a part of the commensal microflora in healthy individuals, during the last years it has been frequently isolated from patients with mucosal and systemic fungal infections. Now it is considered as the second most frequently isolated pathogenic yeast after Candida albicans. Despite its name, C. glabrata is phylogenetically a closer relative to

The increasing trend to build both more and longer underground transportation systems, e.g., road and rail tunnels, and the special characteristics of these facilities, introduces new problem areas to both fire safety designers and fire rescue services. TUFT, a simple computer model, has therefore been developed partly to aid fire safety designers in the early stages of the fire safety design proc

Search algorithms for regular and irregular quasi-cyclic LDPC block codes with both good girth profile and good degree distribution are presented. New QC LDPC block codes of various code rates are obtained and their bit error rate performance is compared with that of the corresponding LDPC block codes defined in the IEEE 802.16 WiMAX standard of the same block length and code rate.

Background: In most clubfoot studies, the outcome instruments used are designed to evaluate classification or long-term cross-sectional results. Variables deal mainly with factors on body function/structure level. Wide scorings intervals and total sum scores increase the risk that important changes and information are not detected. Studies of the reliability, validity and responsiveness of these i

A fluorescence lidar measurement has been performed on the castle Övedskloster in Sweden. A mobile system from the Lund University was placed at ~40 m distance from the sandstone façade. The lidar system, which uses a frequency-tripled Nd:YAG laser with a 355-nm pulsed beam, induces fluorescence in each target point. Areas were studied by using whisk-broom scans. The possibility of detecting biode

A new Reynolds stress transport model (RSTM) aimed for engineering applications is proposed with consideration of near-wall turbulence. This model employs the Speziale, Sarkar and Gatski (SSG) pressure strain term, the omega equation, and the shear stress transport (SST) model for the shear stresses at the near-wall region (say, y(+) < 30). The models are selected based on the following merits: Th

A disaccharide scaffold based on galabiose (Gal1–4Gal) was synthesized. Four different acceptors were evaluated in the -galactosylation and a relationship between the nucleophilicity, yield, and /-selectivity was found. The scaffold contains two orthogonal derivatisation sites, i.e. at O-2′ and the anomeric position, and as proof of concept, one derivatised galabioside was synthesized. Compounds b

Popular Abstract in Swedish Moderna tillverkningsmaskiner är dyra och därför måste dess tillgänglighet och effektivitet ständigt hållas högt. Sådana resultat kan man inte åstadkomma utan tillämpning av en effektiv underhållsstrategi. Förutsättningar för att minska eller arrestera förslitnings hastighet på maskins delar och öka maskinlivslängden är stora vid användning av tillståndsövervakning, (TÖModern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. The main result reported in this thesis is that the rolling element bearing’s mean effective li

OBJECTIVES: To investigate prospectively long term patient relevant outcomes after unilateral total hip replacement (THR) for osteoarthritis (OA). To identify non-responders to this intervention and patient related predictors of unsatisfactory outcome.METHODS: A case-control study comparing health related quality of life of 219 patients (mean age 71) after THR with that of a matched reference grou

Specific granule protein of 28 kDa (SGP28), also termed cysteine-rich secretory protein 3 (CRISP-3), is a glycoprotein that belongs to a family of cysteine-rich secretory proteins (CRISPs). SGP28 was originally discovered in human neutrophils, but transcripts are widely distributed in exocrine glands (salivary glands, pancreas, and prostate) and also found at lower levels in epididymis, ovary, thy

The pharmacokinetics of antimigraine drugs zolmitriptan and sumatriptan varied considerably with a fourfold to 10-fold variation in plasma levels. In addition, the pharmacodynamics of triptans as investigated in vitro also varied considerably. In theory, there should probably be a 10-fold variation in doses available, but in clinical practice a fourfold difference in doses will probably cover the

Idiopathic Scoliosis is a spinal deformity affecting approximately 3% of otherwise healthy children or adolescents. The etiology is still largely unknown but has an important genetic component. Genome-wide association studies (GWAS) have identified a number of common genetic variants that are significantly associated with idiopathic scoliosis in Asian and Caucasian populations, rs11190870 close to
