The phase evolution in a zirconium–50 deuterium (Zr–50D, at.%) alloy system during thermal cycling has been investigated using in situ high-resolution neutron powder diffraction. The results showed that the peritectoid reaction α-Zr + δ-ZrD → γ-ZrD previously suggested to occur at high temperatures does not take place in the system. Slow cooling, from high temperatures (≥520 K) to room temperature

A simple, rapid and environmentally friendly hollow-fibre liquid-phase microextraction (HF-LPME) technique was developed for the quantitative determination of polycyclic aromatic hydrocarbons (PAHs) in aqueous samples. GC-MS was then used as the method of analysis. The HF-LPME technique involves extraction of PAHs from a 20-mL sample containing 20 % acetonitrile as a modifier. The PAHs were extrac

The origin of the new kinematically identified metal-poor stellar stream, the KFR08 stream, has not been established to date. We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Sc, Ti, Cr, Ni, Zn, Sr, Y, Zr, Ba, La, and Eu for 16 KFR08 stream members based on an analysis of high-resolution spectra. Based on the abundance ratios of 14 elements, we

Objective: The aim of this study was to explore healthcare workers' opinions on workplace related health resources relevant to promotion of their health. Participants: 16 registered nurses and 19 assistant nurses, from a medical emergency ward at a medium sized hospital in the south of Sweden, participated in the study. Methods: Eight focus group interviews were conducted, the material was con

Soil organic material (SOM) is usually enriched in (15)N in deeper soil layers. This has been explained by discrimination against the heavier isotope during decomposition or by the accumulation of (15)N-enriched microbial biomass versus plant biomass in older SOM. In particular, ectomycorrhizal (EM) fungi have been suggested to accumulate in old SOM since this group is among the most (15)N-enriche

The effect of antioxidant supplementation on biomarkers of oxidative stress was investigated in a 6-week intervention study in 60 overweight men. The supplement contained a combination of antioxidants aiming to correspond to the antioxidant content found in a diet rich in fruit and vegetables. Placebo, single or double dose of antioxidants was provided to the subjects. Metabolic variables, plasma

Spring phenophases such as the beginning of leaf unfolding, measured in the Irish gardens of the International Phenological Garden (IPG) network, indicate an earlier spring occurrence hence a longer growing season. However, these measurements are limited to selected species of trees at a few point locations in the southern half of the country. The aim of this study was to develop a methodology, ba

In this paper I will examine the interspace where new religious systems and practices in contemporary Sweden meet the secularized society and give rise to a new, enchanted cosmos. I will discuss how this meeting has generated a science-like concept, the potential concept, which I would refer to as a common used notion within contemporary neo-spirituality, since there are similarities between the n

Because of their predetermined selectivity, molecularly imprinted polymers (MIPs) have been extensively investigated to offer efficient separation of organic pollutants for water analysis and purification. In this review, we first describe the current development of water compatible MIPs, and the physical encapsulation and chemical immobilization of MIP particles for practical applications related

This report is the result of study that was performed in January and February 2009. It was presented and reviewed at the Annual Meeting of the Law and Society Association: Law, Power, and Inequality in the 21st Century in May 2009. The study empirically examined, or rather examined the lack of, social norms opposing illegal file sharing. A total of over 1,000 respondents have answered the questio

Radome diagnostics are acquired in the design process, the delivery control, and in performance verification of repaired and newly developed radomes. A measured near or far field may indicate deviations, e.g., increased side-lobe levels, but the origins of the flaws are not revealed. In this paper, radome diagnostics is performed by visualizing the equivalent surface currents on the 3D-radome body

BACKGROUND: Multiple medicine use among elderly persons is likely to be the result of treatment regimens developed over a long period of time. By learning more about how multiple medication use develops, the quality of prescribing may be improved across the adult lifespan. OBJECTIVE: To describe patterns of multiple medicine use in the general Swedish population and its association with sociodemog

Background: Following the 2007 precise measurements of monopole strengths in tin isotopes, there has been a continuous theoretical effort to obtain a precise description of the experimental results. Up to now, there is no satisfactory explanation of why the tin nuclei appear to be significantly softer than Pb-208. Purpose: We determine the influence of finite-range and separable pairing interactio

The World Health Organization/United Nations Children's Fund Baby-Friendly Hospital Initiative: Revised, Updated, and Expanded for Integrated Care (2009) identifies the need for expanding the guidelines originally developed for maternity units to include neonatal intensive care. For this purpose, an expert group from the Nordic countries and Quebec, Canada, prepared a draft proposal, which was dis

Purpose: The resulting plans from a new type of treatment planning system called SharePlan (TM) have been studied. This software allows for the conversion of treatment plans generated in a TomoTherapy system for helical delivery, into plans deliverable on C-arm linear accelerators (linacs), which is of particular interest for clinics with a single TomoTherapy unit. The purpose of this work was to

We investigate electron-ion recombination to excited states in atomic clusters exposed to intense NIR and XUV pulses, which leads to a yet undiscovered autoionization mechanism as a consequence of multiple recombination processes.
