Amorphous surface oxides of III-V semiconductors are harmful in many contexts of device development. Using low-energy electron diffraction and photoelectron spectroscopy, we demonstrate that surface oxides formed at Sn-capped GaAs(100) and InAs(100) surfaces in air are effectively removed by heating. This Sn-mediated oxide desorption procedure results in the initial well-defined Sn-stabilized (1x2
Preterm birth has been associated with increased risk of venous thromboembolism (VTE) in infancy, but the longer-term risk is unknown. Our aim was to examine this association from birth through young adulthood.
3-Hydroxypropionaldehyde (3HPA) is an important C3 chemical that can be produced from renewable glycerol by resting whole cells of Lactobacillus reuteri. However the process efficiency is limited due to substrate inhibition, product-mediated loss of enzyme activity and cell viability, and also formation of by-products. Complex formation of 3HPA with sodium bisulfite and subsequent binding to Amber
A radiocarbon and tephra-dated sediment core from Lifebuoy Lake, located on the north-east coast of Kamchatka Peninsula, was analysed for pollen, spores, diatoms, chironomids and tephra in order to uncover regional environmental history. The 6500-year environmental history of Lifebuoy Lake correlates with the broad regional patterns of vegetation development and climate dynamics with both diatoms
Observational epidemiology has made outstanding contributions to the discovery and elucidation of relations between lifestyle factors and common complex diseases such as type 2 diabetes. Recent major advances in the understanding of the human genetics of this disease have inspired studies that seek to determine whether the risk conveyed by bona fide risk loci might be modified by lifestyle factors
A new glacial geomorphological map of the Eyjabakkajokull forefield in Iceland is presented. The map covers c. 60 km(2) and is based on high-resolution aerial photographs recorded in August 2008 as well as field checking. Landforms are manually registered in a geographical information system (ArcGIS) based on inspection of orthorectified imagery and digital elevation models of the area. We mapped
Six strains isolated from fermented food were by 16S rDNA sequencing identified as Weissella species, clustering with the species-pair W. confusa/ W. cibaria. The strains were analysed for growth on glucose, xylose and xylooligosaccharides (XOS). All strains were xylose positive using the API CHL 50 test. Growth on XOS was observed for strain 85, 92, 145 and AV1, firstly by optical density measure
A methodology for evaluation of natural draft cooling tower (CT) performance and its application is presented. The study establishes the connection between CT performance and power output. It can estimate a change in a CT’s efficiency as well as an increase in power output as a function of cooling water temperature and load to the plant. The methodology consists of three subparts, i.e. Cooling Tow
The development and establishment of a Swedish translation of the Scale of Ethnocultural Empathy (SEE) was investigated in a sample of 788 participants. The SEE is a self-report instrument and is used to measure empathy directed toward people from ethnic cultural groups who are different from the respondent’s own ethnocultural group. Principal components factor analyses and confirmatory factor ana
The Archean Fiskenaesset Complex, SW Greenland, consists of an association of ca. 550-meter-thick layered anorthosite, leucogabbro, gabbro, and ultramafic rocks (peridotite, pyroxenite, dunite, hornblendite). The complex was intruded by tonalite, trondhjemite, and granodiorite (TTG) sheets (now orthogneisses) during thrusting that was followed by several phases of isoclinal folding. The trace elem
Charged-pion-interferometry measurements were made with respect to the second- and third-order event plane for Au+Au collisions at sqrt[s_{NN}]=200 GeV. A strong azimuthal-angle dependence of the extracted Gaussian-source radii was observed with respect to both the second- and third-order event planes. The results for the second-order dependence indicate that the initial eccentricity is reduced du
Objective A pay-for-performance (P4P) programme for primary care was introduced in 2011 by a Swedish county (with 1.6 million inhabitants). Effects on register entry practice and comparability of data for patients with diabetes mellitus were assessed. Design and setting Observational study analysing short-term outcomes before and after introduction of a P4P programme in the study county as compare
To investigate and describe the content, dissemination and effects of case management interventions for informal caregivers of older adults, focusing on outcomes related to patients' activities of daily living, nutrition assessment, pain measurement, depression, length of stay and to caregivers' satisfaction and difficulties.
We examined the association between perceived environmental barriers to outdoor mobility and loneliness among community-dwelling older people. In addition, we studied whether walking difficulties and autonomy in participation outdoors affected this association.
The focus of operations planning and control for manufacturing firms has expanded successively over the last 50 years. New principles, techniques, and systems have emerged that have allowed for new approaches. The perspective for planning and control has expanded from internal production operations to supply chain operations linking suppliers, manufacturers, and customers. In this paper, we take a
Objective. We evaluated in a proof-of-concept double-blind placebo-controlled randomized trial the efficacy and safety of intra-articular sprifermin (recombinant human fibroblast growth factor 18) in patients with symptomatic knee OA. Methods. Sprifermin was evaluated as intra-articular injection at 10, 30, and 100μg. Primary efficacy endpoint was change in central medial femorotibial compartment
