Combined Salt and Temperature Impact on Montmorillonite Hydration

Bentonite is to be used as a sealing material for long-term storage of radioactive waste. During permafrost periods the buffer may freeze, causing the following: montmorillonite dehydration, ice formation, and pressure build-up that may fracture the surrounding rock. No previous study has been done on freezing of bentonite in saline water. Using small and wide angle X-ray scattering, the present s

Ischaemic brain damage after cardiac arrest and induced hypothermia-a systematic description of selective eosinophilic neuronal death. A neuropathologic study of 23 patients.

Although well characterized in animals, brain damage in humans treated with hypothermia after cardiac arrest has not been systematically explored. In this study we aimed to describe the characteristic trait of selective eosinophilic neuronal death (SEND), and its correlation with time to return of spontaneous circulation (ROSC) in cardiac arrest patients who died after hypothermia treatment and we

Computing at School in Sweden - Experiences from Introducing Computer Science within Existing Subjects

Computing is no longer considered a subject area only relevant for a narrow group of professionals, but rather as a vital part of general education that should be available to all children and youth. Since making changes to national curricula takes time, people are trying to find other ways of introducing children and youth to computing. In Sweden, several current initiatives by researchers and te

Conditions on argument drop

This article pursues the idea that null arguments are derived without any statement or parameter, instead following "naturally" from 3rd factor principles and effects (in the sense of Chomsky 2005). The article thus contributes to the program of eliminating statements in grammar in favor of general factors. More specifically, it develops a theory of C/edge linking in terms of syntactically active

Dual-color decompositions at one-loop level in Yang-Mills theory

In this work we extend two dual color decompositions of Yang-Mills amplitude to one-loop level. Starting from double-copy expression we translate the Yang-Mills integrand into the dual Del Duca-Dixon-Maltoni formulation and subsequently to the dual color-ordered formula. The dual trace factors are obtained after simultaneously solving the one-loop Kleiss-Kuijf relations, the reflection relation, a

Performance indices for feedforward control

In this paper, a performance benchmark for the assessment of two feedforward control architectures for the load disturbance compensation problem is proposed. In particular, two indices are devised so that the advantage of using a feedforward compensator with respect to the use of a feedback controller only is quantified. Furthermore, these metrics will help to make quantitative comparisons among d

Structure and Morphology of Wheat Gluten Films: From Polymeric Protein Aggregates toward Superstructure Arrangements

Evaluation of structure and morphology of extruded wheat gluten (WG) films showedWGprotein assemblies elucidated on a range of length scales from nano (4.4 Å and 9 to 10 Å, up to 70 Å) to micro (10 μm). The presence of NaOH in WG films induced a tetragonal structure with unit cell parameters, a = 51.85 Å and c = 40.65 Å, whereasNH4OHresulted in a bidimensional hexagonal close-packed (HCP) structur

C-terminal peptides of tissue-factor pathway inhibitor are novel host defense molecules.

Tissue factor pathway inhibitor (TFPI) inhibits tissue factor-induced coagulation, but may, via its C-terminus, also modulate cell surface-, heparin-, lipopolysaccharide interactions as well as participate in growth inhibition. Here we show that C-terminal TFPI peptide sequences are antimicrobial against the Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, Gram-positive Bacillus

Loneliness and health care consumption among older people.

Few studies have investigated loneliness in relation to health care consumption among frail older people. The aim of this study was to examine loneliness, health-related quality of life (HRQoL), and health complaints in relation to health care consumption of in- and outpatient care among frail older people living at home. The study, with a cross-sectional design, comprised a sample of 153 responde

Sulfur K-edge photofragmentation of ethylene sulfide

We have investigated the photofragmentation properties of the three-membered ring heterocyclic molecule ethylene sulfide or thiirane, C2H4S, by time-of-flight mass spectroscopy. Positive ions have been collected as a function of photon energy around the S K ionization threshold. Branching ratios were derived for all detected ions, which are informative of the decay dynamics and photofragmentation

On the nature of the Mn-related states in the band structure of (Ga,Mn)As alloys via probing the E-1 and E-1 + Delta(1) optical transitions

The dilute (Ga,Mn)As became a model ferromagnetic semiconductor, however there is still a disagreement on the source of its magnetism. In this paper, we verify the ellipsometric results and compare them with more precise photoreflectance method, which gives an important insight into the interaction of the Mn-related states with the ones of GaAs valence band. No spectral shifts observed for the E-1

Gene-centric Meta-analysis in 87,736 Individuals of European Ancestry Identifies Multiple Blood-Pressure-Related Loci.

Blood pressure (BP) is a heritable risk factor for cardiovascular disease. To investigate genetic associations with systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), and pulse pressure (PP), we genotyped ∼50,000 SNPs in up to 87,736 individuals of European ancestry and combined these in a meta-analysis. We replicated findings in an independent set of 68,368 individuals of Europe

How to achieve full prophylaxis in young boys with severe haemophilia A: different regimens and their effect on early bleeding and venous access

To facilitate early prophylaxis, step-up regimens starting prophylaxis with infusions 1xweek(-1) were introduced. Choice of initial regimen may affect outcome. This study aims to classify initial prophylactic regimens and compare them on short-term outcome. From the European Paediatric Network for Haemophilia Management' (PedNet) registry, patients with severe haemophilia A without inhibitors, bor

On traffic domination in communication networks (invited paper)

Input data for communication network design/optimization problems involving multi-hour or uncertain traffic can consist of a large set of traffic matrices. These matrices are explicitly considered in problem formulations for link dimensioning. However, many of these matrices are usually dominated by others so only a relatively small subset of matrices would be sufficient to obtain proper link capa

A comparison between radial strain evaluation by speckle-tracking echocardiography and cardiac magnetic resonance imaging, for assessment of suitable segments for left ventricular lead placement in cardiac resynchronization therapy.

A cut-off of 9.8% maximum speckle-tracking radial strain in the segment with the latest mechanical delay has been proposed as predictive for selecting the best left ventricular lead placement for positive response on cardiac resynchronization therapy (CRT). However, pacing transmural scar should be avoided, and the purpose of this study was to evaluate the ability of echocardiographic radial strai

MicroRNAs as Neuronal Fate Determinants.

Since the discovery of short, regulatory microRNAs (miRNA) 20 years ago, the understanding of their impact on gene regulation has dramatically increased. Differentiation of cells requires comprehensive changes in regulatory networks at all levels of gene expression. Posttranscriptional regulation by miRNA leads to rapid modifications in the protein level of large gene networks, and it is therefore

On infrastructure for facilitation of inner source in small development teams

The phenomenon of adopting open source software development practices in a corporate environment is known by many names, one being inner source. The objective of this study is to investigate how an organization consisting of small development teams can benet from adopting inner source and assess the level of applicability. The research has been conducted as a case study at a software development c
