The intercalation and deintercalation mechanisms of Si deposited on monolayer graphene grown on SiC(0001) substrates and after subsequent annealing steps are investigated using low-energy electron microscopy (LEEM), photoelectron spectroscopy (PES), and micro-low-energy electron diffraction (mu-LEED). After Si deposition on samples kept at room temperature, small Si droplets are observed on the su
Background: The thorough assessment of familial prostate cancer (PCa) risk is as important as ever to provide a basis for clinical counselling and screening recommendations. Objective: Our aim was to determine the age-specific risks of PCa and the risk of death from PCa according to the number and the age of affected first-degree relatives. Design, setting, and participants: The nationwide Swedish
No comprehensive evaluation has been made to assess the risk of viral and bacterial infections among patients with monoclonal gammopathy of undetermined significance. Using population-based data from Sweden, we estimated risk of infections among 5,326 monoclonal gammopathy of undetermined significance patients compared to 20,161 matched controls. Patients with monoclonal gammopathy of undetermined
Background: Several experimental studies have suggested potential anticarcinogenic effects of flavonoids, although epidemiologic evidence for the impact of dietary flavonoids on risk of gastric cancer (GC) is limited. Objective: We investigated the association between intake of dietary flavonoids and lignans and incident GC. Design: The study followed 477,312 subjects (29.8% men) aged 35-70 y from
Background Different healthy food patterns may modify cardiometabolic risk. We investigated the effects of an isocaloric healthy Nordic diet on insulin sensitivity, lipid profile, blood pressure and inflammatory markers in people with metabolic syndrome. Methods We conducted a randomized dietary study lasting for 18-24weeks in individuals with features of metabolic syndrome (mean age 55years, BMI
Molecular analyses of the relationships of placental mammals have shown a progressive congruence between mitogenomic and nuclear phylogenies. Some inconsistencies have nevertheless persisted, notably with respect to basal divergences. The current study has aimed to extend the representation of groups, whose position in the placental tree has been difficult to establish in mitogenomic studies. Both
Molecular dynamics simulations are used to provide a detailed investigation of the hydrogen bond networks around the phosphatidylcholine (PC) head group in 1,2-dipropionyl-sn-glycero-3-phosphocholine in pure water, 10 mol.% and 30 mol.% dimethylsulfoxide (DMSO)-water solutions. Specifically, it is observed that DMSO replaces those water molecules that are within the first solvation shell of the ch
The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this
Background: Ingestion of a meal increases the blood flow to the gastrointestinal organs and affects the heart rate (HR), blood pressure and cardiac output (CO), although the mechanisms are not known. The aim of this study was to evaluate the effect of endogenously released glucose, insulin, glucagon-like peptide 1 (GLP-1), ghrelin on CO, HR, stroke volume (SV), and blood pressure. Methods: Eleven
Abstract in UndeterminedSoil microbes constitute an important control on nitrogen (N) turnover and retention in arctic ecosystems where N availability is the main constraint on primary production. Ectomycorrhizal (ECM) symbioses may facilitate plant competition for the specific N pools available in various arctic ecosystems. We report here our study on the N uptake patterns of coexisting plants an
Background: Mobility is important for the cognitive and psychosocial development of children. Almost one third of children with cerebral palsy (CP) are non-ambulant. Wheelchairs can provide independent mobility, allowing them to explore their environment. Independent mobility is vital for activity and participation and reduces the dependence on caregivers. The purpose of this study was to describe
In most tests of vocabulary size, knowledge is assessed through multiple-choice formats. Despite advantages such as ease of scoring, multiple-choice tests (MCT) are accompanied with problems. One of the more central issues has to do with guessing and the presence of other construct-irrelevant strategies that can lead to overestimation of scores. A further challenge when designing vocabulary size t
Several methods to improve the parton-shower description of hard processes by an injection of matrix-element-based information have been presented over the years. In this article we study (re)weighting schemes for the first/hardest emission. One objective is to provide a consistent matching of the POWHEG next-to-leading order generator to the Pythia shower algorithms. Another is to correct the def
Abstract in Undetermined Experiments on choice blindness support von Hippel & Trivers's (VH&T's) conception of the mind as fundamentally divided, but they also highlight a problem for VH&T's idea of non-conscious self-deception: If I try to trick you into believing that I have a certain preference, and the best way is to also trick myself, I might actually end up having that preference
Surface-patterning technologies have enabled the improvement of currently existing light-emitting diodes (LEDs) and can be used to overcome the issue of low quantum efficiency of green GaN-based LEDs. We have applied nanosphere lithography to fabricate nanopillars on InGaN/GaN quantum-well LEDs. By etching through the active region, it is possible to improve both the light extraction efficiency an
Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. Because the volume of wood is not constant but varies with the moisture content, uneven distribution of moisture will result in induced eigen-stresses because of internal restraint hyg
Thirty correlated alpha-decay chains were observed in an experiment studying the fusion-evaporation reaction 48Ca + 243Am at the GSI Helmholtzzentrum f¨ur Schwerionenforschung. The decay characteristics of the majority of these 30 chains are consistent with previous observations and interpretations of such chains to originate from isotopes of element Z = 115. High-resolution alpha-photon coinciden
Popular Abstract in English This thesis is about industrialised house-building, put in a strategic perspective. Industrialised house-building is in the thesis described as a process- and product-oriented concept that can serve as an alternative to traditional project-oriented house-building methods and principles. It is seen as an integrated, multi-disciplinary concept that requires an establishedIndustrialised house-building has received increasing attention within both the construction industry and the scientific community during the last 15 years. However, industrialisation of house-building is not a new phenomenon, it has been applied to various extents throughout modern history, although the understanding and descriptions of it have developed over time. Scientifically, industrialised
