Control of GaP and GaAs Nanowire Morphology through Particle and Substrate Chemical Modification.
We demonstrate two very different morphologies for GaP and GaAs nanowires grown by Au-assisted MOVPE on Si(111) substrates: rodlike wires and tapered wires with sharp tips. We show that the morphology is related to the stability of the particles at the wire tips during growth, and we propose that the mechanism of this effect is diffusion of Au away from the tip. Diffusion occurs, leading to tapere
Quest for the lost siblings of the Sun
Aims. The aim of this paper is to find lost siblings of the Sun by analyzing high resolution spectra. Finding solar siblings will enable us to constrain the parameters of the parental cluster and the birth place of the Sun in the Galaxy. Methods. The solar siblings can be identified by accurate measurements of metallicity, stellar age and elemental abundances for solar neighbourhood stars. The sol
How can we be moral when we are so irrational?
Normative ethics usually presupposes background accounts of human agency, and although different ethical theorists might have different pictures of human agency in mind, there is still something like a standard account that most of mainstream normative ethics can be understood to rest on. Ethical theorists tend to have Rational Man, or at least some close relative to him, in mind when constructing
Subjective health complaints in adolescent victims of cyber harassment: moderation through support from parents/friends - a Swedish population-based study.
Victimization in cyberspace has emerged as a new public health issue among the young. The main purpose of this study was to analyze associations between cyber victimization defined as cyber harassment (CH) (a somewhat broader concept than cyberbullying) and subjective health complaints (SHC), to study whether these associations were modified by parental/friend support (measured as communication),

Neurogenesis from Neural Stem Cells, Ependymal Cells and Fibroblasts
Popular Abstract in Swedish Stroke är en ledande orsak till dödlighet och handikapp i hela världen. Stroke leder till förlust av nervceller och även andra celler i hjärnan på grund av bristande blodtillförsel. För tillfället finns väldigt få möjligheter att behandla funktionshinder relaterade till stroke. Det har visats att stroke leder till ökad neurogenes, nybildning av nervceller i hjärnan. DenStroke is a major cause of death and disability around the world. Stroke leads to loss of neurons and also other cells in the brain due to lack of blood supply. Currently no therapies are available to treat stroke-related disability. It has been shown that stroke leads to increased neurogenesis, birth of new neurons, within the brain. This increased neurogenesis is not sufficient to restore lost f
Influence of Familial Renal Glycosuria Due to Mutations in the SLC5A2 Gene on Changes in Glucose Tolerance over Time.
Familial renal glycosuria is an inherited disorder resulting in glucose excretion in the urine despite normal blood glucose concentrations. It is most commonly due to mutations in the SLC5A2 gene coding for the glucose transporter SGLT2 in the proximal tubule. Several drugs have been introduced as means to lower glucose in patients with type 2 diabetes targeting SGLT2 resulting in renal glycosuria
A Randomized, Doubleblind, Placebo-Controlled, Study of Single-Dose Rituximab as Induction in Renal Transplantation
We performed a prospective, double blind, randomized, placebo-controlled multicenter study on the efficacy and safety of rituximab as induction therapy, together with tacrolimus, mycophenolate mofetil, and steroids. The primary endpoint was defined as acute rejection, graft loss, or death during the first 6 months. Secondary endpoints were creatinine clearance, incidence of infections, and inciden
The Origin, Development and Molecular Diversity of Rodent Olfactory Bulb Glutamatergic Neurons Distinguished by Expression of Transcription Factor NeuroD1.
Production of olfactory bulb neurons occurs continuously in the rodent brain. Little is known, however, about cellular diversity in the glutamatergic neuron subpopulation. In the central nervous system, the basic helix-loop-helix transcription factor NeuroD1 (ND1) is commonly associated with glutamatergic neuron development. In this study, we utilized ND1 to identify the different subpopulations o

An experimental and theoretical core-level study of tautomerism in guanine
The core level photoemission and near edge X-ray photoabsorption spectra of guanine in the gas phase have been measured and the results interpreted with the aid of high level ab initio calculations. Tautomers are clearly identified spectroscopically, and their relative free energies and Boltzmann populations at the temperature of the experiment (600 K) have been calculated and compared with the ex
Mycophenolic Acid Exposure after Administration of Mycophenolate Mofetil in the Presence and Absence of Ciclosporin in Renal Transplant Recipients
Background and objective: The pharmacokinetics of mycophenolic acid (MPA) are complex, with large interindividual variability over time. There are also well documented interactions with ciclosporin, and assessment of MPA exposure is therefore necessary when reducing or stopping ciclosporin therapy. Here we report on the pharmacokinetic and pharmacodynamic behaviour of MPA in renal transplant patie
S’Villanorvm de Malmøghae. Landskap, urbanitet, aktörer och Malmö
The title of the article: S’Villanorum de Malmøghae, refers to an inscription on a seal from a letter written in the year of 1350, sent by the council of Malmö to their colleagues in Rostock. The motif depicts a Romanesque church flanked by the moon and a star, and the inscription states that the letter was sent on behalf of the burghers of Malmö. The seal reveals a message that Malmö should be re
Co-digestion of grease trap sludge and sewage sludge.
Redirection of organic waste, from landfilling or incineration, to biological treatment such as anaerobic digestion is of current interest in the Malmö-Copenhagen region. One type of waste that is expected to be suitable for anaerobic digestion is sludge from grease traps. Separate anaerobic digestion of this waste type and co-digestion with sewage sludge were evaluated. The methane potential was
Mechanisms by which variants in the TCF7L2 gene increase the risk of developing Type 2 diabetes
Popular Abstract in Chinese 概括 II型糖尿病的發展趨勢在全世界範圍內非常迅速。我國目前有超過九千萬II型糖尿病患者,另外有大量血糖不正常的糖尿病高危人群。其中只有三成病人對自己的病情有所了解。II型糖尿病的病人與日俱增。 說到糖尿病,自然就會想到胰島素,以及血糖和胰島素的關系。胰島素是人體中非常重要的激素(荷爾蒙)。人體所需要的糖分主要是從食物中的澱粉類食物(米飯,面食)中來的,肉類也含有一部分的糖分。糖分從小腸吸收進入血液循環。胰島素的功能是讓身體細胞把血液中的糖分吸收進入細胞(比如肌肉細胞)加以使用,同時降低血液中的血糖成份。如果胰島素分泌不足,或者人體細胞對胰島素的敏感性降低會引起血糖升高,長期高血糖會損害血管和臟器的健康,最終導致糖尿病並發癥的發生。糖尿病並發癥是一種常見的慢性並發癥,後果相當嚴重,足部壞疽、腎功能衰竭、尿毒癥、視力模糊不清、失明、腦血Type 2 diabetes mellitus (T2DM) is a heterogeneous disease with a multifactorial aetiology comprising of genetic and environmental factors. The common variant most highly associated with T2DM known to date is a SNP rs7903146 in the TCF7L2 gene. However, the role TCF7L2 plays in the development of T2DM was unclear. Clinical, animal and in vitro studies have revealed an association of the risk T-all
Klassrummet som muntlig arena. Att bygga och etablera ethos.
Popular Abstract in Swedish Ett grundantagande för avhandlingen Klassrummet som muntlig arena. Att bygga och etablera ethos är att en människa som med trovärdighet vill kunna verka som en demokratisk medborgare i olika kommunikationssituationer måste besitta kommunikativ kompetens. Följaktligen hänger demokrati och kommunikativ kompetens tätt samman. En viktig trovärdighetsfaktor i sammanhanget ärThe Class Room as an Oral Arena: Building and Establishing Ethos starts with the premise that every person who wants to act credibly as a democratic citizen must have a communicative competence. Democracy and communicative competence are closely linked. To communicate credibly is to communicate with ethos. The purpose of this dissertation is to study how students in Swedish gymnasium build and est
Framing problems in radical innovation
The challenge of managing radical innovation is partly about dealing with higher levels of uncertainty as organisations seek to extend their exploration into new technological and market spaces. Innovation management routines for dealing with this differ from those around incremental innovation — the well-established exploit/explore dilemma. But it can be argued that there is a second challenge as
Revised transmembrane orientation of the NADH:quinone oxidoreductase subunit NuoA.
NuoA is a small membrane spanning subunit of respiratory chain NADH:quinone oxidoreductase (complex I). Unlike the other complex I core protein subunits, the NuoA protein has no known homologue in other enzyme systems. The transmembrane orientation of NuoA cannot be unambiguously predicted, due to the small size of the polypeptide and the varying distribution of charged amino acid residues in NuoA
NADH- vs NADPH-coupled reduction of 5-hydroxymethyl furfural (HMF) and its implications on product distribution in Saccharomyces cerevisiae.
Saccharomyces cerevisiae alcohol dehydrogenases responsible for NADH-, and NADPH-specific reduction of the furaldehydes 5-hydroxymethyl-furfural (HMF) and furfural have previously been identified. In the present study, strains overexpressing the corresponding genes (mut-ADH1 and ADH6), together with a control strain, were compared in defined medium for anaerobic fermentation of glucose in the pres
