The electronic structure of strongly correlated systems is usually calculated by using an effective model Hamiltonian with a small number of states and an effective on-site interaction. The mode, however, neglects the frequency dependence of the interaction, which emerges as a result of dynamical screening processes not included in the model. The self-energy calculated in this kind of model within
Background: Women working in the public human service sector in 'overstrained' situations run the risk of musculoskeletal symptoms and long-term sick leave. In order to maintain the level of health and work ability and strengthen the potential resources for health, it is important that employees gain greater control over decisions and actions affecting their health - a process associated with the
Traditional, pre-industrial farming was adapted to the natural environment-topography, geology, hydrology, climate, and biota. Traditional land use systems are still to be traced in Scandinavia as an "infield/outland landscape", and in Japan as a "Satoyama landscape." There are obvious similarities and differences in land use-the main difference being that pasturing of cattle and sheep has been le
Efficient pretreatment is necessary to make the wood-to-ethanol process more feasible. In this study, chips of different sizes were impregnated with SO(2) and steam-pretreated. Dilute-acid pretreatment together with subsequent enzymatic hydrolysis resulted in solubilization of between 69% and 73% of the fermentable sugars (glucose and mannose) in the raw material for the combinations of impregnati
BACKGROUND: The two-gene expression ratio HOXB13:IL17BR has been proposed to predict the outcome of tamoxifen-treated breast cancer patients. We intended to examine whether this ratio can predict the benefit of 5 years vs. 2 years of tamoxifen treatment of postmenopausal patients. A further objective was to investigate any prognostic effects of the ratio in systematically untreated premenopausal p
The overall aim of the thesis was to investigate and explore job satisfaction, strain and stress of conscience (SC) among nurse assistants (NAs) working in residential care for older people. The thesis had a descriptive, cross-sectional and correlational design and consisted of one paper where qualitative methodology was used and three where quantitative methodology was used. The qualitative study
Here we report the first survey of galectin binding to glycoproteins of human serum. Serum was subjected to affinity chromatography using immobilized galectins, and the bound glycoproteins were analyzed by electrophoresis, Western blotting, and mass spectrometry. Galectins-3, -8 and -9 bound a much broader range of ligands in serum than previously known, galectin-1 bound less, and galectins-2, -4
Hormone-mediated maternal effects play an important role in the formation of a differentiated phenotype. They have been shown to influence a wide array of offspring traits, both early in life and in adulthood. One important offspring trait that is under the influence of maternal androgens is the immune system. In birds, a growing number of studies show that yolk androgens modulate immune function
Abstract For activity quantification based on planar scintillation camera measurements, photon attenuation is an important factor that needs to be corrected for in a patient- and organ-specific manner. One possibility for obtaining attenuation correction maps is to use X-ray CT scout images. Since the intensity of scout images is in relative numbers, their image values need to be multiplied by a f
We use multiscale modeling to analyze laser-induced fluorescence (LIP) measurements of the CO oxidation reaction over Pd(100) at near-ambient reaction conditions. Integrating density functional theory-based kinetic Monte Carlo simulations of the active catalyst into fluid-dynamical simulations of the mass transport inside the reactor chamber, we calculate the reaction product concentration directl
This study quantified major fluxes of carbon (C), heat and water, including uncertainty estimates, in a boreal forest in northern Sweden, using a process-based model (Coup-Model) and Bayesian calibration methodology. Coupled C, water and heat fluxes were described together with estimated uncertainties for all major components of the simulated C budget. Simulated mean gross primary production was 6
Modal shift from private cars to high quality public transport is often seen as a means for improved traffic safety while simultaneously achieving other policy goals. This paper aims to describe safety from a travel-chain perspective and suggests an approach for using accident data as performance indicators. Findings from a recent Swedish case study of bus accidents show that the number of unrepor
A decade has passed since the first human embryonic stem cell (hESC) line was established, providing immense hope in curing diseases by cell replacement therapy. For instance, in the pancreas, the insulin-producing β-cells are damaged in diabetes patients, and a successful replacement of those cells could provide a cure. These cells can be replaced by organ donation, but owing to a profound scarci
OBJECTIVE: To estimate the accuracy of endometrial thickness measurement in the detection of endometrial cancer among women with postmenopausal bleeding with individual patient data using different meta-analytic strategies. DATA SOURCES: Original data sets of studies detected after reviewing the included studies of three previous reviews on this subject. An additional literature search of publishe
People's preferences for income inequality vary, and this research investigates the influence of socioeconomic status on these preferences. Drawing on a structural position theory that considers individuals’ self-interest and rationality to be driven by their socioeconomic status, this paper examines the extent to which socioeconomic status affects the likelihood of accepting income inequality
In this thesis I study international space law’s rules on international responsibility and international liability for private satellite launches. I have used a legal dogmatic method to interpret these rules, before subjecting them to an economic analysis on how they will affect the behaviour of private actors and States. Finally I propose solutions to increase the economic efficiency of three dif
The study explores the influence of agro-processing activities in the lives and livelihoods of cassava farmers in five communities located in four districts in the Ashanti and Volta regions in Ghana. The qualitative research is done by performing thirty-six semi-structured interviews to farmers and stakeholders along the cassava value chain. The research concludes that agro-processing activities a
Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. This report concerns the Dissipating Energy Flow (DEF), which is an energy-based method for analysing dampi
The purpose of this thesis was to explore how a newly founded Youth Platform in Colombia, called La Mesa de Juventud, could affect the youth community in promoting and capacitating organizational skills, youth citizenship rights and youth influence in public policy making. The study emanates from the region of northern Cauca situated in the South Western part of Colombia which is an area where you
