The moult of Barred Warblers Sylvia nisoria was studied during three winter seasons in southeastern Kenya at a southward passage site (Ngulia) and a wintering site (Mtito Andei). Most Barred Warblers migrating through Ngulia in November had yet to commence winter moult. These birds probably moulted subsequently in winter in northern Tanzania. In December, birds were found in heavy moult at Mtito A

Byggnationen av bostadshus med trästomme har enligt Statistiska centralbyrån ökat med 85% efter den senast lägsta uppmätningen 2011. Statistiska centralbyrån menar också att det är bostadshus bestående av 4-8 våningar som byggs mest i Sverige idag. Av denna statistik förutspås det bli en ökning av efterfrågan på bostadshus med 4-8 våningar med trästomme inom den närmsta framtiden. Tillsammans meThe construction of residential buildings with timber as load-bearing system has according to Statistics Sweden increased with 85% since 2011, which is the latest low point of the collected data. Statistics Sweden also shows how residential buildings consisting of 4-8 storeys are, in Sweden, the most built type of house today. Of these statistics, 4-8- storey residential buildings made with timber

BACKGROUND: Pyrazinamide (PZA) is a key drug in the treatment of tuberculosis (TB), including multidrug-resistant TB. Drug susceptibility testing (DST) of Mycobacterium tuberculosis against PZA is not included in the World Health Organization's yearly proficiency testing. There is an increasing need to establish quality control of PZA DST. OBJECTIVE: To evaluate the performance of PZA DST and to i

Popular Abstract in Swedish I den här avhandlingen studeras de elektriska egenskaperna hos nanotrådar av halvledarmaterial. En halvledare är ett mellanting av en ledare och en isolator, där den elektriska ledningsförmågan kan styras både genom att förorena materialet med andra ämnen och genom att påverka materialet med ett elektriskt fält. I princip all modern elektronik bygger på komponenter av hThis thesis focuses on electron transport in semiconductor InAs/InP and InSb nanowire quantum devices. However, first the temperature dependence of classical charge transport in InSb nanowire field-effect transistors, FETs, is characterized, using InAs nanowire FETs as a reference. We find that the InSb FETs, in the same way as InAs FETs, are n-type with good current saturation and low voltage ope

Popular Abstract in Swedish Studier av cystatin C's funktion in vitro och in vivo.Cystatin C variants with Arg8, Leu9 and/or Val10 replaced by Gly residues were produced by site-directed mutagenesis and E. coli expression. Their interactions with the target proteases, cathepsin B, L, H and S, were studied in vitro in order to provide basic structure-function information of use in the design of specific inhibitors for therapeutic use. Val10 was shown to be the most contributing

Outcome questionnaires are increasingly being established as a validated mode of acquiring unbiased information on the results after health interventions. Using an assortment of questionnaires, distributed by mail to 27 372 and to a subgroup of 3 600 patients on file in the Swedish Knee Arthroplasty register (SKAR), relevant questionnaires were found to represent a feasable means of acquiring info

Hematopoiesis is a lifelong, dynamic process in which a small number of pluripotent hematopoietic stem cells (HSC) residing in the bone marrow (BM) give rise to billions of mature blood cells of both myeloid and lymphoid origin each day. This enormous capacity of HSC has been utilized in BM transplantations for 4 decades and is also very important for future gene therapy. Understanding what molecu

Popular Abstract in Swedish Det svenska samhället har under senare delen av 1900-talet påverkats och förändrats på grund av en ökad internationell migration. År 1950 var 2,8 % av den svenska befolkningen utrikesfödd; idag utgör de utrikesfödda 12,0 % av totalbefolkningen. Om även andragenerationens migranter (de som har en eller båda föräldrar utrikesfödda) räknas med utgör första och andrageneratAims: The general aim of this thesis was to describe and compare the group of foreign-born persons living in Sweden and native Swedes with regard to health development over time, thus studying the influence of migration on health. Methods: All four studies are based on data from Statistics Sweden (SCB) and the National Board of Health and Welfare, Centre for Epidemiology covering the period 1970?

Geographical variations in cardiovascular mortality have been reported from Mid-Sweden. IHD mortality for men aged 45-64 was 60% higher in the western part than in the east. Mortality from stroke for men aged 45-74 was 73% higher on the west. Similar differences were found for women. One possible explanation could be that there are no incidence differences but that the mortality differences are du

Popular Abstract in Swedish Stroke är en av de ledande dödsorsakerna i västvärlden och det finns idag ingen behandling för funktionell återställning. Efter stroke ökar den striatala neurogenesen och de nybildade neuroblasterna vandrar mot det skadade området. Denna respons har ansetts vara av akut och övergående art. I denna avhandling har en modell av experimentell stroke använts (2 h of middle cStroke is a leading cause of death and disability for which there is no treatment for functional recovery. Following stroke, striatal neurogenesis is increased, with newly formed neuroblasts migrating towards the damage. This response has so far been considered acute and transient. In this thesis, a model of experimental stroke (2 h of middle cerebral artery occlusion, MCAO) used to study three a

OBJECTIVES: To assess quality of life in patients with varying degrees of ischaemia in comparison with controls, and to determine whether the degree of lower limb ischaemia and sense of coherence were associated with quality of life. MATERIALS AND METHODS: 168 patients, including 93 claudicants and 75 patients with critical ischaemia and 102 controls were studied. Quality of life was assessed usin

Thalli of Nephroma arcticum were transplanted between and within a high-elevation alpine heath (1100 m) and a low-elevation subalpine mountain birch forest (380 m) in northern Swedish Lapland and harvested after eight years. Statistically significant differences (P < 0.05) were found between control samples for dark respiration rates, photon use efficiencies (apparent quantum yields) and light com

Cobalt silicide has emerged as a leading contact material in silicon technology due to its low resistivity, high stability and small lattice mismatch. In this study, 0.2-0.4 mu m thick Co films were deposited on Si(100) wafers by RF magnetron sputtering at room temperature, and annealed at temperatures from 600 to 900 degrees C in vacuum. As-deposited and annealed samples were characterized by Rut

We have previously proposed the use of Doppler ultrasound to noninvasively stage a sinus infection. In this study, we first investigated the acoustic properties of nonpurulent and mucopurulent sinus secretions. The density, viscosity, speed of sound and attenuation of 18 samples of sinus fluid were examined. We then assessed the safety of the method by determining the temperature increase when ult
