Magnetic anisotropy investigations of (Ga,Mn)As with a large epitaxial strain

Magnetic properties of 20 nm thick (Ga,Mn)As layer deposited on (Ga,ln)As buffer with very large epitaxial tensile strain are investigated. Gal,In,As buffer with x=30% provides a 2% lattice mismatch, which is an important extension of the mismatch range studied so far (up to 0.5%). Evolution of magnetic anisotropy as a function of temperature is determined by magnetotransport measurements. Additio

Protection of feet in cold exposure

The paper summarizes the research on cold protection of feet. There exist several conflicting requirements for the choice of the best suited footwear for cold exposure. These conflicts are related to various environmental factors, protection needs and user comfort issues. In order to reduce such conflicts and simplify the choice of proper footwear the paper suggests dividing the cold into specific

The article treats freemasonry as an integrated part of sociability among European military elites.

Efficacy of the natural antioxidant astaxanthin in the treatment of functional dyspepsia in patients with or without Helicobacter pylori infection: A prospective, randomized, double blind, and placebo-controlled study

Objectives: The aim of this study was to evaluate the efficacy of the natural antioxidant astaxanthin in functional dyspepsia in different doses and compared with placebo. Design: The study was a controlled, prospective, randomized, and double blind trial. Participants: Patients with functional dyspepsia, divided into three groups with 44 individuals in each group (placebo, 16 mg, or 40 mg astaxan

On the validity of neurodevelopmental disorders

Popular Abstract in Swedish Introduktion: Validitet handlar enkelt uttryckt om överensstämmelse med sanningen eller exempelvis om ett instrument mäter det som är avsett. Validitet kan också ses som ett mer komplext begrepp, innefattande aspekter som nytta, relevans, värderingar och sociala konsekvenser. Validitet förutsätter reliabilitet som är ett mått på tillförlitlighet, noggrannhet eller reproAbstract Introduction: Validity is important at different levels in psychiatry. Valid structured instruments are important aids in screening and diagnostics, in both research and clinical practice. An aim of the diagnostic procedure is to yield valid diagnoses. Ultimately, the validity of structured instruments (non-empirical) and clinical diagnoses depends on the validity of the diagnostic class

The impact of patient heterogeneity and socioeconomic factors on abatacept retention in rheumatoid arthritis across nine European countries.

There are substantial differences in accessibility to biological disease modifying antirheumatic drugs (bDMARDs) across countries. The objective of this study was to analyse the impact of patient demographics, disease characteristics and gross domestic product (GDP) on abatacept (ABA) retention in patients with rheumatoid arthritis (RA) treated in clinical practice.

The Nile and the Grand Ethiopian Renaissance Dam: Is There a Meeting Point between Nationalism and Hydrosolidarity?

The soon-to-be completed Grand Ethiopian Renaissance Dam (GERD), which will be the largest hydroelectric power plant and among the largest reservoirs in Africa, has highlighted the need for expanding traditional integrated water resources management to better include the cultural, social, and political complexities of large water infrastructure in development projects. The GERD will store a maximu

Chronic non-transmural infarction has a delayed recovery of function following revascularization

Background: The time course of regional functional recovery following revascularization with regards to the presence or absence of infarction is poorly known. We studied the effect of the presence of chronic nontransmural infarction on the time course of recovery of myocardial perfusion and function after elective revascularization. Methods: Eighteen patients (mean age 69, range 52-84, 17 men) pro

Physiological characteristics of the extreme thermophile Caldicellulosiruptor saccharolyticus: an efficient hydrogen cell factory

Global concerns about climate changes and their association with the use of fossil fuels have accelerated research on biological fuel production. Biological hydrogen production from hemicellulose-containing waste is considered one of the promising avenues. A major economical issue for such a process, however, is the low substrate conversion efficiency. Interestingly, the extreme thermophilic bacte

Conceptions of Copyright in a Digital Context. A Comparison between French and American File-sharers

What type of metaphors do file-sharers employ to conceptualise copyright in a digital society? How do they understand property and intellectual property in this context? How do they conceive the file-sharing community and how does this ‘online piracy’ connect or not connect to law, social norms, copyright enforcement, and computational traceability? Given the historical variations in the inherent

Dose-densified chemoimmunotherapy followed by systemic central nervous system prophylaxis for younger high-risk diffuse large B-cell/follicular grade 3 lymphoma patients: results of a phase II Nordic Lymphoma Group study

Background: Many patients with aggressive B-cell lymphomas and high clinical risk score still die of lymphoma after conventional R-CHOP chemoimmunotherapy. We hypothesized that intensified chemoimmunotherapy including systemic central nervous system (CNS) prophylaxis improves outcome and reduces the incidence of CNS-related events. Patients and methods: Inclusion criteria were age 18-65 years, pri

Subspace estimation and prediction methods for hidden Markov models

Hidden Markov models (HMMs) are probabilistic functions of finite Markov chains, or, put in other words, state space models with finite state space. In this paper, we examine subspace estimation methods for HMMs whose output lies a finite set as well. In particular, we study the geometric structure arising from the nonminimality of the linear state space representation of HMMs, and consistency of

From disease to genes in animal models of rheumatoid arthritis and multiple sclerosis

Rheumatoid arthritis (RA) and multiple sclerosis (MS) are complex inflammatory autoimmune diseases. The aetiology is largely unknown but the risk of developing disease is dependent on both genetic and environmental factors. Extensive efforts have been done to identify the underlying genes in order to understand the molecular mechanisms of the diseases. Until recently, only a few genes have been qu
