Semiconductor nanowires have attracted considerable attention during the last decade and are considered as an alternative path to extend the road for scaled semiconductor devices. The interest is motivated by the improved electrostatic control in the cylindrical geometry and the possibility to utilize heterostructures in transistor design. Currently, nanowire transistors have been realized both in
The North Atlantic Oscillation (NAO), a measure of the strength of the zonal wind across the North Atlantic Ocean, strongly influences weather conditions in NW Europe, e.g. temperature, precipitation and wind, especially during winter. It was hypothesised that elevated concentrations of nitrogen oxides in Gothenburg would be enhanced during negative NAO index (NAOI) conditions, representing more a
To identify susceptibility loci for classical Hodgkin's lymphoma (cHL), we conducted a genome-wide association study of 589 individuals with cHL (cases) and 5,199 controls with validation in four independent samples totaling 2,057 cases and 3,416 controls. We identified three new susceptibility loci at 2p16.1 (rs1432295, REL, odds ratio (OR) = 1.22, combined P = 1.91 x 10(-8)), 8q24.21 (rs2019960,
We use monodisperse poly(N-isopropylacrylamide) (PNIPAM) microgels as a model system for soft repulsive colloids and study their density dependent structural ordering and phase behaviour using confocal laser scanning microscopy (CLSM). The experiments are carried out at low temperatures, where the particles are in the swollen state and interact via a Hertzian potential, evidenced through a quantit
Popular Abstract in Swedish Intresset för utmattning har ökat både i Sverige och internationellt under de senaste årtiondena. Utmattning som begrepp är oklart definierat vetenskapligt, och det finns olika benämningar på utmattningstillstånd, som till exempel den något gammalmodiga benämningen neurasteni, som ännu finns kvar som diagnos-klassifikation (där även benämnt ”trötthetssyndrom”), kronisktThe interest in exhaustion has increased rapidly during the last few decades in many developed countries. In Sweden, prevalence of exhaustion increased by 50 percent on average between 1989 and 2005, and recent data reveals that exhaustion still remains at this higher level. Scientifically, exhaustion is not clearly defined. Chronic stress is acknowledged to give rise to exhaustion, but specific m
In the coming years, it is anticipated that if we continue with the same pace of energy consumption, communities will continue to face three major challenges; a mounting increase in energy demands, pollution, and global warming. On a local scale, Egypt is experiencing one of its most serious energy crises in decades. The energy consumed in indoor cooling and heating is the biggest portion of total
The production of pi(+), pi(-), K+, K-, p, and (p) over bar at mid-rapidity has been measured in proton-proton collisions at root s = 900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. In addition, time-of-flight information is used to identify hadrons at higher momenta. Finall
Popular Abstract in Swedish När vi äter socker frisätter kroppen hormonet insulin från specifika beta-celler i bukspottskörteln för att förmå muskelceller och fettceller att ta upp sockret från blodet och därmed återställa blodets sockerbalans. Vid övervikt blir dessa vävnader resistenta mot insulinets verkan vilket leder till att sockret stannar kvar i blodet. Detta vill kroppen undvika då en förThere are many contributing factors to the development of type 2 diabetes, however, failure of beta-cells to sufficiently secrete insulin is the key component. The underlying mechanism of beta-cell failure is not fully established. In this thesis, we examined the role of high glucagon levels, i.e. hyperglucagonemia, for the development of beta-cell dysfunction in pre-diabetic mice. We found that i
Oxidative stress has been implicated as an important factor in the progression of many diseases. An imbalance in the redox-system may cause oxidation of cells and molecules, which might subsequently lead to tissue damage. The research presented in this thesis has focused on elucidating a possible involvement of the human protein alpha-1-microglobulin in the defence against pathological oxidation.
Molecular weight (MW) is one of the most important characteristics of macromolecules. Sometimes, MW cannot be measured correctly by conventional methods like gel permeation chromatography (GPC) due to, for example, aggregation. We propose using single-molecule spectroscopy to measure the average MW simply by counting individual fluorescent molecules embedded in a thin matrix film at known mass con
Using genome-wide association, we identify common variants at 2p12-p13, 6q26, 17q23 and 19q13 associated with serum creatinine, a marker of kidney function (P = 10(-10) to 10(-15)). Of these, rs10206899 (near NAT8, 2p12-p13) and rs4805834 (near SLC7A9, 19q13) were also associated with chronic kidney disease (P = 5.0 x 10(-5) and P = 3.6 x 10(-4), respectively). Our findings provide insight into me
The polemics of Solomon Adret, Bahya ben Asher, and Abraham Bibago are presented, based on my book: Shield and Sword. 1993.
OBJECTIVE: To elucidate parent´s experience of having had a baby with colic four years previously and of how the colic and care influenced the family in a long-term perspective. METHODOLOGY AND PARTICIPANTS: A qualitative inductive follow-up study with 13 individual and one focus group interview including four parents. Altogether ten mothers and seven fathers representing 12 families, who had been
A measurement of W boson production in lead-lead collisions at root s(NN) = 2.76 TeV is presented. It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated luminosity of 0.14 nb(-1) and 0.15 nb(-1) in the muon and electron decay channels, respectively. The differential production yields and lepton charge asymmetry are each measured as
Despite a history of conflicts and widespread human rights violation in sub-Saharan Africa, little is known about the prevalence of interpersonal violence among the population in this region. Evidence from high-income countries suggests that exposure to violence has mental health consequences and violence also has associations with experiences of sexual coercion.

Introduction: Studies have shown that executive dysfunction is common in adults after stroke. Occupational therapists working in acute care assess the performance of activities of daily living; most instruments focus on personal care. However, the assessment of instrumental activities of daily living has been shown to discriminate executive dysfunction more effectively. An instrument for assessing
