The solid solution Gd2NixCu2-xMg: Large reversible magnetocaloric effect and a drastic change of the magnetism by substitution
Various samples of the solid solution Gd2NixCu2-xMg were synthesized from the elements in sealed tantalum ampoules in an induction furnace. All members crystallize with the tetragonal Mo2FeB2 type structure, space group P4/mbm, and they were characterized on the basis of Guinier powder patterns and energy dispersive X-rays analyses. The lattice parameters decrease with increasing nickel content in
Contrast-to-noise ratio optimization for a prototype phase-contrast computed tomography scanner.
In the field of biomedical X-ray imaging, novel techniques, such as phase-contrast and dark-field imaging, have the potential to enhance the contrast and provide complementary structural information about a specimen. In this paper, a first prototype of a preclinical X-ray phase-contrast CT scanner based on a Talbot-Lau interferometer is characterized. We present a study of the contrast-to-noise ra
The adaptive background of nannandry: dwarf male distribution and fertilization in the moss Homalothecium lutescens
Dwarf males (nannandry) occur in many unrelated, mostly aquatic, groups of organisms. Among land plants they are unique to bryophytes. In this study our aim was to explain variation in frequency of dwarf males and fertilization within populations in the moss Homalothecium lutescens. We compared parameters related to dwarf male presence and sporophyte production in 90 colonies from three localities
Structural and optical properties of self-catalytic GaAs:Mn nanowires grown by molecular beam epitaxy on silicon substrates
Mn-doped GaAs nanowires were grown in the self-catalytic growth mode on the oxidized Si(100) surface by molecular beam epitaxy and characterized by scanning and transmission electron microscopy, Raman scattering, photoluminescence, cathodoluminescence, and electron transport measurements. The transmission electron microscopy studies evidenced the substantial accumulation of Mn inside the catalyzin
Genetic variation in FADS genes is associated with maternal long-chain PUFA status but not with cognitive development of infants in a high fish-eating observational study.
Long-chain n-6 and n-3 PUFA (LC-PUFA), arachidonic acid (AA) (20:4n-6) and DHA (22:6n-3), are critical for optimal brain development. These fatty acids can be consumed directly from the diet, or synthesized endogenously from precursor PUFA by Δ-5 (encoded by FADS1) and Δ-6 desaturases (encoded by FADS2). The aim of this study was to determine the potential importance of maternal genetic variabilit
Evaluating the responsiveness of the ICOAP following hip or knee replacement
Objective: The Intermittent and Constant Osteoarthritis (OA) Pain (ICOAP) questionnaire evaluates the constructs of 'intermittent' and 'constant' pain. Theses are conceptually different from 'pain on activity' and pain 'intensity' as measured by the WOMAC and Chronic Pain Grade (CPG), measures commonly used in OA. The purpose of this study was to evaluate the responsiveness of the ICOAP, and diffe
Anaesthetic conserving device AnaConDa®: dead space effect and significance for lung protective ventilation.
The anaesthetic conserving device AnaConDa(®) (ACD) reflects exhaled anaesthetic agents thereby facilitating the use of inhaled anaesthetic agents outside operating theatres. Expired CO2 is, however, also reflected causing a dead space effect in excess of the ACD internal volume. CO2 reflection from the ACD is attenuated by humidity. This study tests the hypothesis that sevoflurane further attenua
Physical activity in persons with late effects of polio: A descriptive study.
To promote a healthy and active lifestyle there is a need to increase our knowledge of the level of physical activity (PA) among people with late effects of polio.
Direct and indirect impacts of climate and socio-economic change in Europe : a sensitivity analysis for key land- and water-based sectors
Integrated cross-sectoral impact assessments facilitate a comprehensive understanding of interdependencies and potential synergies, conflicts, and trade-offs between sectors under changing conditions. This paper presents a sensitivity analysis of a European integrated assessment model, the CLIMSAVE integrated assessment platform (IAP). The IAP incorporates important cross-sectoral linkages between
Contested expectations: Trump International Golf Links Scotland, polarised visions, and the making of the Menie Estate landscape as resource
In initiating the development of a large-scale golf resort in Aberdeenshire, Trump International Golf Links Scotland made a relatively unknown site central to Scottish planning debates. A stretch of land along the North Sea coast north of Aberdeen became linked to new possible futures. Part of the site developed consisted of moving sand dunes given environmental protection as a Site of Special Sci
Neuron-Specific Enolase as a Predictor of Death or Poor Neurological Outcome After Out-of-Hospital Cardiac Arrest and Targeted Temperature Management at 33°C and 36°C.
Neuron-specific enolase (NSE) is a widely-used biomarker for prognostication of neurological outcome after cardiac arrest, but the relevance of recommended cutoff values has been questioned due to the lack of a standardized methodology and uncertainties over the influence of temperature management.
Patients experiences of information and support during the first six months after heart or lung transplantation.
BACKGROUND: Heart or lung recipients are taught about a new lifestyle, risk factors, medication, food restrictions and exercise so they can take an active role and responsibility for disease management after transplantation. However, little is known about patients' experiences of information and support in these situations. OBJECTIVE: The aim of the study was to illuminate how patients, six months
Psychometric properties of a Swedish version of the Consequences of Screening - Breast Cancer questionnaire.
To evaluate the psychometric properties of a questionnaire addressing psychosocial consequences of false-positive mammographic screening.
Recombinant antibodies for the generation of antibody arrays.
Affinity proteomics, mainly represented by antibody microarrays, has in recent years been established as a powerful tool for high-throughput (disease) proteomics. The technology can be used to generate detailed protein expression profiles, or protein maps, of focused set of proteins in crude proteomes and potentially even high-resolution portraits of entire proteomes. The technology provides uniqu
Early-Middle Ordovician conodont biofacies on the Yangtze Platform margin, South China: Applications to palaeoenvironment and sea-level changes
9172 Conodonts have been recovered from the uppermost Hunghuayuan Formation and the Zitai Formation at two sections in Shitai County, southern Anhui Province, South China, which was situated close to the margin of the Lower Yangtze Platform during the Early to Middle Ordovician. Systematic and multivariate statistical studies on these conodonts permit recognition of seven conodont biofacies: Tropo
STrengthening the Reporting of OBservational studies in Epidemiology-Molecular Epidemiology (STROBE-ME): An Extension of the STROBE Statement
Influence of Internal DNA Pressure on Stability and Infectivity of Phage λ.
Viruses must remain infectious while in harsh extracellular environments. An important aspect of viral particle stability for double-stranded DNA viruses is the energetically unfavorable state of the tightly confined DNA chain within the virus capsid creating pressures of tens of atmospheres. Here, we study the influence of internal genome pressure on the thermal stability of viral particles. Usin
Capacitive sensing of microcystin variants of Microcystis aeruginosa using a gold immunoelectrode modified with antibodies, gold nanoparticles and polytyramine
We report on the application of an automated and easy-to-use device to directly measure the immunoreactions between adda-specific monoclonal antibodies and microcystins. The antibodies were immobilized on a gold electrode whose surface was modified first with polytyramine and then with gold nanoparticles. The immunoreaction leads to a change in the capacitance of the system. Under optimum conditio
Characterizing the high-velocity stars of RAVE: the discovery of a metal-rich halo star born in the Galactic disc
We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). We used a sample of 57 HiVel stars with Galactic rest-frame velocities larger than 275 km s(-1). With 6D position and velocity information, we integrated the orbits of the HiVel stars and found that, on average, they reac
