Local atomic structure around Mn ions in GaN:Mn thin films: Quantitative XANES analysis

GaN:Mn dilute magnetic semiconductors with zinc-blende type of lattice and room temperature ferromagnetism were investigated by the X-ray absorption near edge structure (XANES) with a high accuracy approach of the multidimensional interpolation, which makes it possible to determine the nanoscale local atomic structure around Mn impurities. It is found that Mn atoms are substantially incorporated i

Morphological and electronic properties of epitaxial graphene on SiC

We report on the structural and electronic properties of graphene grown on SiC by high-temperature sublimation. We have studied thickness uniformity of graphene grown on 4H-SiC (0 0 0 1), 6H-SiC (0 0 0 1), and 3C-SiC (1 1 1) substrates and investigated in detail graphene surface morphology and electronic properties. Differences in the thickness uniformity of the graphene layers on different SiC po

Inflammatory biomarkers in serum in subjects with and without work related neck/shoulder complaints

Background: Although it has recently been recognised that inflammation is important in the development of work-related musculoskeletal disorders (MSDs), the exact pathophysiological pathways are unknown. Methods: We investigated serum concentrations of inflammatory cytokines in 35 female supermarket cashiers with repetitive work tasks and work related neck/shoulder complaints, compared with those

Verktyg för optimering av byggtorkning

För att bättre kunna kostnadsoptimera byggtorkningar har ett optimeringsverktyg innefattande ett antal olika beräknings och bedömningsparametrar tagits fram. Byggtorkning innefattar stora kostnader för energi, provisorier och kontroller. Vid misslyckade byggtorkningar adderas det ytterligare kostnader via fuktskador samt ökade omkostnader på grund av byggtorkningar som drar ut på tiden. Alternativ

EBF1 is essential for B-Lineage priming and establishment of a transcription factor network in common lymphoid progenitors

Development of B-lymphoid cells in the bone marrow is a process under strict control of a hierarchy of transcription factors. To understand the development of a B-lymphoid-restricted functional network of transcription factors, we have investigated the cell autonomous role of the transcription factor EBF1 in early B cell development. This revealed that even though transplanted EBF1-deficient fetal

The Armenian Genocide of 1915 from a Neutral Small State’s Perspective : Sweden

This study depicts how the Armenian massacres in the Ottoman Empire during World War I were perceived by a neutral small state, namely, Sweden. The Swedish knowledge should be of special interest since, as a neutral state during the entire conflict, Sweden had no immediate involvement or interest in the ongoing conflict; thus, any reporting about the events would have been untainted compared to th

Energy considerations for a SSF-based softwood ethanol plant

Ethanol can be produced from softwood by steam pretreatment followed by simultaneous saccharification and fermentation (SSF). However, the final ethanol concentration in the SSF step is usually rather low (around 4 wt%) and as a result the energy demand in the downstream processing will be high. In an effort to reduce the energy consumption various alternatives for the downstream processing part o

Validation of ACG Case-mix for equitable resource allocation in Swedish primary health care

Background: Adequate resource allocation is an important factor to ensure equity in health care. Previous reimbursement models have been based on age, gender and socioeconomic factors. An explanatory model based on individual need of primary health care (PHC) has not yet been used in Sweden to allocate resources. The aim of this study was to examine to what extent the ACG case-mix system could exp

Food intake of individuals with and without diabetes across different countries and ethnic groups

Background/Objectives: Given the importance of nutrition therapy in diabetes management, we hypothesized that food intake differs between individuals with and without diabetes. We investigated this hypothesis in two large prospective studies including different countries and ethnic groups. Subjects/Methods: Study populations were the European Prospective Investigation into Cancer and Nutrition Stu

Genetic polymorphisms in breast cancer in relation to risk and prognosis

Breast cancer is the most common cancer in women living in Sweden and the second most common cancer in the rest of the world. The risk of developing breast cancer is modified by environment, lifestyle, genetics and a combination of these factors. In this thesis work the combination of lifestyle and genetic polymorphisms on tumor characteristics and early recurrence have been studied. Absence of th

Moderate varus/valgus malalignment after total knee arthroplasty has little effect on knee function or muscle strength 91 patients assessed after 1 year

Background and purpose - Postoperative muscle strength and component alignment are important factors affecting functional results after total knee arthroplasty (TKA). We are not aware of any studies that have investigated the relationship between them. We therefore investigated whether coronal malalignment of the mechanical axis and/or of individual implant components would affect knee muscle stre

Diversity, Loss, and Gain of Malaria Parasites in a Globally Invasive Bird.

Invasive species can displace natives, and thus identifying the traits that make aliens successful is crucial for predicting and preventing biodiversity loss. Pathogens may play an important role in the invasive process, facilitating colonization of their hosts in new continents and islands. According to the Novel Weapon Hypothesis, colonizers may out-compete local native species by bringing with

Macroscopic effects in attosecond pulse generation

We examine how the generation and propagation of high-order harmonics in a partly ionized gas medium affect their strength and synchronization. The temporal properties of the resulting attosecond pulses generated in long gas targets can be significantly influenced by macroscopic effects, in particular by the intensity in the medium and the degree of ionization which control the dispersion. Under s

Leading logarithms in the anomalous sector of two-flavour QCD

We add the Wess-Zumino-Witten term to the N = 3 massive nonlinear sigma model and study the leading logarithms in the anomalous sector. We obtain the leading logarithms to six loops for pi(0) -> gamma*gamma* and to five loops for y*pi pi pi. In addition we extend the earlier work on the mass and decay constant to six loops and the vector form factor to five loops. We present numerical results for

Comparison of soil salinity and solute transport for different cultivated soil types in northeastern Egypt

The soil salinity distribution and solute transport properties of three different soil types were investigated and compared within a project area in northeastern Egypt. For this purpose, dye tracer experiments and salinity sampling were carried out. The resulting salinity maps showed that the soil salinity in the cultivated western site of the project area is 8-10 times higher than that in the cul

The Voice of the Patient

Popular Abstract in Swedish Allergiska besvär från luftvägarna utgör ett stort och växande folkhälsoproblem. Det finns idag ingen bot mot dessa sjukdomar och de kan, om de inte behandlas, utgöra ett betydande hinder i vardagen. Även om dagens mediciner i de allra flesta fall kuperar symtomen väl, vet man, att många patienter är odiagnostiserade eller saknar behandling trots diagnos. Målet med behAllergic diseases, which constitute a global health problem, have been defined as one of the epidemics of the twenty-first century. Since there are no cures for allergic diseases today, the goal of treatment is to get the disease under control so that the patient can live a normal life with optimal chances of development. Patient-reported outcomes for control assessment have been a focus of attent

Monoclonal gammopathy of undetermined significance (MGUS) and smoldering (asymptomatic) multiple myeloma: IMWG consensus perspectives risk factors for progression and guidelines for monitoring and management

Monoclonal gammopathy of undetermined significance (MGUS) was identified in 3.2% of 21 463 residents of Olmsted County, Minnesota, 50 years of age or older. The risk of progression to multiple myeloma, Waldenstrom's macroglobulinemia, AL amyloidosis or a lymphoproliferative disorder is approximately 1% per year. Low-risk MGUS is characterized by having an M protein < 15 g/l, IgG type and a normal
