InAs Nanowire Devices and Circuits

Popular Abstract in Swedish Sedan introduktionen av transistorn och den integrerade kretsen har teknologin inom halvledarindustrin utvecklats i en mycket hög takt. Genom att bygga allt mindre och snabbare transistorer har en exponentiell förbättring av prestanda bibehållits sedan 1960-talet, ett fenomen känt som Moores Lag. Fram tills nyligen har utvecklingen mot högre prestanda och fler transistoSince the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. Today, billions of transistors are integrated on a single chip and the size of a transi

The current role of beta-blockers in chronic heart failure: with special emphasis on the CIBIS III trial

Beta-blockers (bisoprolol, metoprolol succinate, carvedilol, and to some extent nebivolol), given on top of angiotensin-converting enzyme (ACE) inhibitors, improve survival and reduce morbidity in symptomatic stable chronic heart failure (CHF). Early beta-blockade may help to improve survival and especially prevent sudden death, but the usual practice of starting the ACE inhibitor first may lead t

Impact of comorbidity on the individual's choice of primary health care provider.

Abstract Objective. This study examined whether age, gender, and comorbidity were of importance for an individual's choice of listing with either a public or a private primary health care (PHC) practice. Design and setting. The study was a register-based closed cohort study in one private and one public PHC practice in Blekinge County in southern Sweden. Subjects. A cohort (12 696 individuals) was

Towards the multi-scale simulation of martensitic phase-transformations: An efficient post-processing approach applied to turning processes

This work presents an efficient finite element based scheme for the prediction of process properties and especially the material condition of workpiece surfaces after turning. This is achieved by using a database generated with the help of a micromechanically motivated material model - capable of simulating interactions of phase transitions and plasticity - for the efficient post-processing of a m

Global expression analysis of the yeast Lachancea (Saccharomyces) kluyveri reveals new URC genes involved in pyrimidine catabolism

Pyrimidines are important nucleic acid precursors which are constantly synthesized, degraded, and rebuilt in the cell. Four degradation pathways, two of which are found in eukaryotes, have been described. One of them, the URC pathway, has been initially discovered in our laboratory in the yeast Lachancea kluyveri. Here, we present the global changes in gene expression in L. kluyveri in response to

Peer-group support intervention improves the psychosocial well-being of AIDS orphans: Cluster randomized trial

Accumulating evidence suggests that AIDS orphanhood status is accompanied by increased levels of psychological distress such as anxiety, depression, intense guilt, shame, and anger. However, few studies have examined the possible reduction of psychological distress in AIDS orphans through the help of interventions that promote well-being. The objective of the study was to evaluate the effects of a

Primary assembly of soil communities: disentangling the effect of dispersal and local environment.

It has long been recognised that dispersal abilities and environmental factors are important in shaping invertebrate communities, but their relative importance for primary soil community assembly has not yet been disentangled. By studying soil communities along chronosequences on four recently emerged nunataks (ice-free land in glacial areas) in Iceland, we replicated environmental conditions spat

Galectin Inhibitors – Molecular Tools in Biomedical Research and Clinical Implications

Galectins are β-galactoside-binding lectins, which are present in both the intracellular and extracellular environments of cells. During the last two decades, galectins have gained increasing interest as drug targets in various diseases, such as chronic inflammation (fibrosis) and cancer, in which galectins have been shown to play important, and sometimes rate-limiting, roles. Galectins have e.g.

Clinical preventive services for patients at risk for cardiovascular disease, National Ambulatory Medical Care Survey, 2005-2006

INTRODUCTION: Clinical preventive services can detect diseases early, when they are most treatable, but these services may not be provided as recommended. Assessing the provision of services to patients at risk for cardiovascular disease (CVD) could help identify disparities and areas for improvement.METHODS: We used data on patient visits (n = 21,261) from the National Ambulatory Medical Care Sur

Siliceous Raw Material Exploitation at Hort de la Boquera Site (Margalef de Monsant, Tarragona, España) : First Results from La-Icp-Ms Analysis

Research on the sourcing of siliceous raw materials in Prehistory has taken a step forward with the addition of geochemical techniques and elemental analysis to the archaeopetrological method. Counter to the macroscopic techniques, which retain an elevated subjective percentage in their results, geochemical techniques and especially LA-ICP-MS analysis generate objective, quantifiable and usable da

Increased frequency of retinopathy of prematurity over the last decade and significant regional differences

Purpose: Retinopathy of prematurity (ROP) causes childhood blindness globally in prematurely born infants. Although increased levels of oxygen supply lead to increased survival and reduced frequency of cerebral palsy, increased incidence of ROP is reported. Methods: With the help of a Swedish register for ROP, SWEDROP, national and regional incidences of ROP and frequencies of treatment were evalu

Analysis and exploitation of resource efficiency potentials in industrial small and medium-sized enterprises – Experiences with the EDIT Value Tool in Central Europe

Material and energy costs represent about 50% of the operating costs incurred by European small and medium-sized enterprises (SMEs). Although the potential for resource efficiency improvements is high, the necessary awareness and human resource capacities to explore this potential are limited. Existing tools for exploration of resource efficiency improvement potentials have several shortcomings: t

Cost-effectiveness of tacrolimus ointment vs. standard treatment in patients with moderate and severe atopic dermatitis: a health-economic model simulation based on a patient survey and clinical trial data.

Background Atopic dermatitis (AD) affects health and quality of life (QoL) and also has great impact on both healthcare costs and costs to society. Objectives The aim of the study was to analyse the cost-effectiveness of treatment with tacrolimus ointment vs. standard treatment in patients with moderate to severe AD. Methods A Markov simulation model was constructed capturing several key features

Social Jetlag and Its Association With Screen Time and Nighttime Texting Among Adolescents in Sweden : A Cross-Sectional Study

The discrepancy between social and biological clock due to sleep and wake up time difference across weekdays and weekends is referred as social jetlag. The overall aim of this study is to test whether there is an association between both screen time and nighttime texting and social jetlag among 13- to 15-year-old adolescents in Sweden. This study included a cross-sectional survey in which data wer

Modelling long-term cost-effectiveness of health promotion for community-dwelling older people

The effectiveness of health promotion for community-dwelling older people is well documented; however, there is a general lack of health economic evaluations. The aim of the present study was to evaluate long-term cost-effectiveness over 4 years of two health promoting interventions: senior meetings and a preventive home visit, for community-dwelling older people in relation to no intervention. We

Topology optimization of non-linear, dissipative structures and materials

Topology optimization is a mathematical tool for finding optimal distributions of material phases within a design domain. It is commonly used in early design stages to generate conceptual structural layouts. Ultimately, designs generated by topology optimization consist of distinct material phases with enhanced performance. Most research on topology optimization methods focuses on linear elastic m

Metalinguistic relativity : Does one's ontology determine one's view on linguistic relativity?

Linguistic relativity is a notion that has been met with both praise and scorn. We argue that there is correlation between theorists’ general conceptions of the nature of language, and their stance toward linguistic relativity. Starting with the proponents of the thesis, we distinguish between the relativists of the early days (Boas, Whorf) and modern neo-Whofians (Levinson, Slobin), showing that

Fragmentation and the problem of fit in the governing of flood risk mitigation

Flood risk is a great global concern that is not only affecting developing countries, but threatens to undermine sustainable development also in the most affluent advanced liberal democracies. While political inertia is delaying much needed global change, efforts to reduce risk and adapt to a changing climate are growing on more local levels. However, floods tend not to be bounded by geopolitical,

This study investigates the internal cooling processes affected by the tip bleed holes in gas turbine blades. Double bleed holes are fixed at the center of the blade tip near the pressure side and suction side, respectively. Five different arrangements of the holes along the center line of the tip are studied. The purely double holes are set as the Baseline. The purpose of the present study is to

I huvudet på en skallsparkare - Om uppsåt och rubricering vid sparkar mot huvudet

Uppsatsen behandlar den rättsliga innebörden av sparkar mot huvudet, för att ge en juridiskt relevant helhetsbild. Grundproblematiken som undersöks är huruvida domstolarna kan döma för mordförsök i större utsträckning än vad som sker idag, istället för misshandelsbrott. Problematiken undersöks ur två aspekter av konformitetsprincipen, enligt vilken bara den som kunnat rätta sig efter lagen bör strThis paper covers the legal aspects of kicking to the head, in order to provide a relevant juridical overall picture. The main issue being examined is whether or not the court can convict someone for attempted murder to a greater extent than is the case today, instead of assault. The problem is examined in two aspects of the Swedish principle of conformity, according to which only a person who cou
