Synthesis and decomposition mechanisms of ternary Mg2FeH6 were investigated using in-situ synchrotron radiation powder X-ray diffraction (SR-PXD) and high-pressure differential scanning calorimetry (HP-DSC). Two routes for synthesis of Mg2FeH6 were studied. The first utilizes a ball-milled homogeneous MgH2-Fe powder mixture and the second uses a mixture of Fe and Mg formed by decomposition of the

Rural depopulation is a concern in many countries, and various policy initiatives have been taken to combat such trends. This article examines whether hidden potential for rural population growth can be found in Sweden. If such potential exists, it implies that the development prospects for many rural areas are not as unpromising as they may seem today. If not, rapid rural depopulation can be expe

Prostate-specific antigen (PSA) and human glandular kallikrein 2 (hK2) are secreted by the prostate into seminal plasma and through leakage into blood. This leakage increases rapidly in prostate disease, and PSA is used worldwide as a marker of prostate cancer. PSA is activated in vitro by hK2, and cleaves the semenogelins in semen, which releases motile sperm, and low levels of PSA have been asso

Rheumatoid arthritis (RA) is a systemic disease, with an increased risk of co-morbidity from cardiovascular disease (CVD), in particular among those with severe disease. Environmental risk factors are of potential interest for both prevention and treatment of RA. Our aim was to examine changes in the occurrence of CVD over time and, using immunohistochemistry, study markers of inflammation in vas

Objective Guidelines on histopathological techniques and reporting for adult and paediatric gastrointestinal neuromuscular pathology have been produced recently by an international working group (IWG). These addressed the important but relatively neglected areas of histopathological practice of the general pathologist, including suction rectal biopsy and full-thickness intestinal tissue. Recommend

Background To evaluate the effects of a case management intervention for frail older people (aged 65+ years) by cost and utility. Materials and methods One hundred and fifty-three frail older people living at home were randomly assigned to either an intervention (n = 80) or a control group (n = 73). The 1-year intervention was carried out by nurses and physiotherapists working as case managers, w

The promoting effect of SO2 on the activity for methane oxidation over platinum supported on silica, alumina and ceria has been studied using a flow-reactor, in situ infrared spectroscopy and in situ high-energy X-ray diffraction experiments under transient reaction conditions. The catalytic activity is clearly dependent on the support material and its interaction with the noble metal both in the

In the growth of nanoscale device structures, the ultimate goal is atomic-level precision. By growing III-V nanowires in a transmission electron microscope, we measured the local kinetics in situ as each atomic plane was added at the catalyst-nanowire growth interface by the vapor-liquid-solid process. During growth of gallium phosphide nanowires at typical V/III ratios, we found surprising fluctu

Background Progression of joint destruction in rheumatoid arthritis (RA) is partly heritable; knowledge of genetic factors may increase our understanding of the mechanisms underlying joint destruction. The activity of the Wnt/beta-catenin pathway influences osteoblast differentiation. Dickkopf-1 (Dkk-1) and sclerostin (Sost) are negative regulators and lipoprotein receptor-related protein-5 (LRP-5

Background: Screening for bacterial colonization among risk populations could provide better estimates of the volume of the bacteria-related disease reservoir and the level of antimicrobial resistance, than do conventional laboratory reports. Methods: Two hundred and one participants at 10 Swedish nursing homes were screened for colonization with Staphylococcus aureus between January and October 2

Endotoxin exposure associated with organic dust exposure has been studied in several industries. Coffee cherries that are dried directly after harvest may differ in dust and endotoxin emissions to those that are peeled and washed before drying. The aim of this study was to measure personal total dust and endotoxin levels and to evaluate their determinants of exposure in coffee processing factories

This article discusses opportunities and challenges of physical layer security integration in MaMIMO systems. Specifically, we first show that MaMIMO itself is robust against passive eavesdropping attacks. We then review a pilot contamination scheme that actively attacks the channel estimation process. This pilot contamination attack not only dramatically reduces the achievable secrecy capacity bu

This dissertation discusses aspects of the syntax of Övdalian, a variety spoken by ca. 2,500 people in the province of Dalecarlia in Sweden. Initially, an overview of the history and current status of the language of Älvdalen is given, and the focus of the dissertation is on certain syntactic phenomena that have been well studied from a comparative and diachronic perspective in other Scandinavian

Purpose: To characterize the clinical phenotype regarding retinal function and macular appearance in patients with spinocerebellar ataxia type 7 (SCA 7), with an emphasis on electrophysiological findings. Methods: Three patients from two Swedish families were given an ophthalmological examination including visual acuity, fundus inspection, Farnsworth's color vision test, Goldmann perimetry, full-f

Patrick Chamoiseau is arguably the most prominent cultural personality from the French island of Martinique. His reputation is due to the worldwide success of his novels, especially Texaco, winner of the Prix Goncourt-award in 1992, but also to the fact that he is the leading theorist of the Créolité, an ideological movement whose aim is to preserve the character of Creole identity and culture aga

This work describes the two-way coupling performed between the regional atmospheric model Brazilian Regional Atmospheric Modeling System (BRAMS) and the hydrological model MGB-IPH. As a first step of the atmosphere-hydrology coupling, only the water balance variables were coupled. Differences in temporal and spatial scales between MGH-IPH and BRAMS were analyzed. By default, MGB-IPH has a daily ti

The production of a [Formula: see text] boson in association with a [Formula: see text] meson in proton-proton collisions probes the production mechanisms of quarkonium and heavy flavour in association with vector bosons, and allows studies of multiple parton scattering. Using [Formula: see text] of data collected with the ATLAS experiment at the LHC in [Formula: see text] collisions at [Formula:

A homologous series of chiral bis-ketals and mixed hemiketal-ketals with rigid bicyclo[3.3.1]-3,7-dioxanonane skeleton has been prepared. The crystallization mode (conglomerate or racemic compound) was established by chiral HPLC with double UV/polarimetric detection. The study of the solid-state structure by single crystal X-ray diffraction disclosed interesting CH ... pi intermolecular interactio

Context: This paper analyses a sub-contractor specification in the mobile handset domain. Objective: The objective is to understand how quality requirements are specified and which types of requirements exist in a requirements specification from industry. Method: The case study is performed in the mobile handset domain, where a requirements specification was analyzed by categorizing and characteri
