Controlling the Abruptness of Axial Heterojunctions in III-V Nanowires: Beyond the Reservoir Effect

Heterostructure nanowires have many potential applications due to the avoidance of interface defects by lateral strain relaxation. However, most heterostructure semiconductor nanowires suffer from persistent interface compositional grading, normally attributed to the dissolution of growth species in the common alloy seed particles. Although progress has been made for some material systems, most bi

Extreme Values of Climatic Thermal Stresses in Concrete Box Cross-section

The thermal stresses in a concrete bridge are affected by the surrounding climate. Varying temperature will produce movements which, if restrained, may induce stresses in the structure. To predict the thermal stresses in box cross-sections, FE simulations have been performed with extensive climatic input data to simulate the temperature and resulting stress fields in the hollow concrete arch of th

Exaggerated orientation scatter of nocturnal passerine migrants close to breeding grounds: comparisons between seasons and latitudes

Using tracking radars, we investigated the variability of flight directions of long-distance nocturnal passerine migrants across seasons (spring versus autumn migration) and sites at the southern (56A degrees N) and northern (68A degrees N) ends of the Scandinavian Peninsula (Lund versus Abisko). Whilst most migrants at Lund are on passage to and from breeding sites in Fennoscandia, the majority o

Musculoskeletal pain is associated with very low levels of vitamin D in men: results from the European Male Ageing Study

Introduction A study was undertaken to test the hypothesis that musculoskeletal pain is associated with low vitamin D levels but the relationship is explained by physical inactivity and/or other putative confounding factors. Methods Men aged 40-79 years completed a postal questionnaire including a pain assessment and attended a clinical assessment (lifestyle questionnaire, physical performance tes

Going Green : A Study of Public Procurement Regulation

Popular Abstract in Swedish Offentlig upphandling blir alltmer intressant och relevant som ämnesområde då dess sanna ekonomiska värde och potentiella inverkan på marknader - genom köpkraft – uppdagas. Det har dessutom blivit ett relevant område för hållbarhetsdiskursen då man har kommit att inse möjligheten att ställa miljökrav inom ramen för den offentliga upphandlingen, samt miljöanpassa upphandIn Sociology of Law the discussions about regulation have been extensive and the issue of public procurement is gaining momentum as its true financial value and potential to impact markets are realised. This thesis aims to look at the regulation of green public procurement (GPP) by analysing findings from an in-depth case study in a Swedish context, using interviews with procurement officers as we

Remnant magnetoresistance effect at the intersection of two ferromagnetic (Ga,Mn)As nanowires

Cross-like nanostructures composed of two perpendicular ferromagnetic (Ga,Mn)As nanowires were fabricated using electron-beam lithography patterning. Nanostructures of different orientations with respect to the crystallographic axes of the parent (Ga,Mn)As epitaxial layer were studied. Electrical resistance of individual nanowires as a function of applied magnetic field were investigated at low te

Ungdomarnas beskrivningar – uppskattning, kritik och förväntningar

Syftet med denna studie är att analysera hur ungdomar som varit placerade på särskilda ungdomshem upplever, definierar och tolkar ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de tolkade de i projektet anställda samordnarna. Den personliga aspekten i relationen mellan ungdomar och samordnare framställs som viktig och det verkThe purpose of this study is to analyse the way young people who were institutionalised in so called special youth-homes experienced, defined and iterpreted on the one hand the project “Motverka Våld och Gäng” (meaning: “Counteract Violence and Gangs”), and on the other hand the Coordinators employed in this project. There is a big variation in the perception of the coordinators. One common deno

Non-thermal production of pure hydrogen from biomass: HYVOLUTION

The objectives and methodology of the EU-funded research project HYVOLUTION devoted to hydrogen production from biomass are reviewed. The main scientific objective of this project is the development of a novel two-stage bioprocess employing thermophilic and phototrophic bacteria, for the cost-effective production of pure hydrogen from multiple biomass feedstocks in small-scale, cost-effective indu

Isotopic investigation of human provenience at the eleventh century cemetery of Ndr. Grødbygård, Bornholm, Denmark

Bornholm is a Danish island almost in the center of the southern Baltic Sea. The strategic location of the island, its rich archeology, and its complex geology make it an intriguing location for the isotopic study of past human mobility. The focus of this study is on the large cemetery of Ndr. Grødbygård in the southern part of the island, which dates to the eleventh century AD and contains 553 in

Alpha-ketoglutarate (AKG) inhibits proliferation of colon adenocarcinoma cells in normoxic conditions

Background and objective. Alpha-ketoglutarate (AKG), a key intermediate in Krebs cycle, is an important biological compound involved in the formation of amino acids, nitrogen transport, and oxidation reactions. AKG is already commercially available as a dietary supplement and its supplementation with glutamine, arginine, or ornithine alpha-ketoglutarate has been recently considered to improve anti

The use of normal and heat-treated barley flour and waxy barley starch as anti-staling agents in laboratory and industrial baking processes

Normal and heat-treated barley, both as flour and waxy starch, were added at a concentration of 3% to a white wheat bread. The effect not only of selected additives, but also of laboratory- and industrial baking processes on stalling was evaluated. Laboratory baked breads with heat-treated barley flour differed from control breads with regard to water content, firmness and amylopectin retrogradati

A diatom record of mid- to late Holocene palaeoenvironmental changes in the southern Okinawa Trough

Palaeoceanographic changes over the last 6800 years are documented in a diatom record from core MD05-2908 from the southern Okinawa Trough. Changes in diatom components are used to reflect variations in the strength of the Kuroshio Current and the influence of coastal waters, and these changes are compared with records of the East Asian summer monsoon, which exerts an important influence on region

Between-Monitor Differences in Step Counts Are Related to Body Size: Implications for Objective Physical Activity Measurement

Background: The quantification of the relationships between walking and health requires that walking is measured accurately. We correlated different measures of step accumulation to body size, overall physical activity level, and glucose regulation. Methods: Participants were 25 men and 25 women American Indians without diabetes (Age: 20-34 years) in Phoenix, Arizona, USA. We assessed steps/day du

Object shift and optionality. An intricate interplay between syntax, prosody and information structure

The topic of my article is Object Shift and optionality, mainly from a Swedish viewpoint. I present the result of a survey, which shows that informant‟s intuitions concerning the wellformedness of shifted and non-shifted sentences vary to a large degree. For sentences with monotransitive verbs and monosyllabic object pronouns, such as den (it.common) ‟it‟, the shifted alternative is preferred, whe

Variations in Quality Indicators of Acute Stroke Care in 6 European Countries: The European Implementation Score (EIS) Collaboration.

BACKGROUND AND PURPOSE: Quality indicators serve as standards of care by which performance of individual hospitals is measured. Although several audits for monitoring quality of stroke care have been established in Europe, there is currently no consensus on quality indicators for acute stroke care or for methodology for collecting information on these measures. METHODS: An up-to-date inventory on

Critical periods during childhood and adolescence

We identify the ages that constitute sensitive (or critical) periods in children's development towards their adult health status, skills, and human capital. For this, we use data on families migrating into Sweden from countries that are poorer, with less healthy conditions. Late-life health is proxied by adult height and other adult outcomes. The relation between siblings' ages at migration and th
