Electron mean free path (MFP) was determined by the angular resolved photoemission in 10-40 eV energy range for GaAs(100)-c(4 x 4) by the overlayer method. The investigation was based on the attenuation of the normal photoemission intensity of the Al 2p line from the molecular-beam-epitaxy grown GaAlAs layer buried four monolayers of GaAs below the surface. The energy dependence of the MFP shows a
The coronary arteries of the isolated rabbit heart were perfused with different contrast media (CM). The effects on cardiac contractile force (CF) from enriching iohexol solutions with sodium, calcium, potassium, magnesium and oxygen were investigated. The effects were studied during normal and reduced perfusion pressure; the latter was intended to simulate flow conditions distal to proximal steno
Premixed turbulent flame-based technologies are rapidly growing in importance, with applications to modern clean combustion devices for both power generation and aeropropulsion. However, the gain in decreasing harmful emissions might be canceled by rising combustion instabilities. Unwanted unsteady flame phenomena that might even destroy the whole device have been widely reported and are subject t
In migratory birds, arrival date and hatching date are two key phenological markers that have responded to global warming. A body of knowledge exists relating these traits to evolutionary pressures. In this study, we formalize this knowledge into general mathematical assumptions, and use them in an ecoevolutionary model. In contrast to previous models, this study novelty accounts for both traits-a
The present study collected and analyzed flow boiling data points which fall in the annular flow regime with an increasing heat transfer coefficient h - vapor quality x trend (h increases with increasing x) in small diameter channels (0.1 < dh < 3.1 mm) for halogenated refrigerants, CO2 and water. In this annular flow regime, heat transfer coefficient also depends on both heat flux and mass flux.
DNA microarray technology has been a valuable tool to provide a global view of the changes in gene expression that characterize different types of B cell lymphomas, both in relation to clinical parameters but also in comparison with the non-malignant counterparts. The number of transcripts that can be analyzed on an array has dramatically increased, and now most commercially available arrays cover
The aim of this study was to verify the advanced inhomogeneous dose distribution produced by a volumetric arc therapy technique (RapidArc) using 3D gel measurements and Monte Carlo (MC) simulations. The TPS (treatment planning system)-calculated dose distribution was compared with gel measurements and MC simulations, thus investigating any discrepancy between the planned dose delivery and the actu
Different actors identified the circular economy (CE) as a solution to tackle global environmental challenges and foster sustainable growth. Transitioning to CE requires new circular business models (CBM), which create, capture, and deliver value, based on the principles of the CE. It is, however, a challenging process for companies see through the wide variety of CBM types and to identify which C
The aim with this master thesis was to investigate if a certain sow feed requires different calibrations in near-infrared analysis, due to if the sow feed have fish oil or AkoFeed as fat source. To investigate this, a basic sow feed mix was prepared and divided in 60 jars with 250 g in each. In 30 of the jars 0 to 15 g fish oil were added and in the other 30 jars 0 to 21 g AkoFeed were added. 2/
Den 7 oktober 2020 presenterades utredningen Ett särskilt hedersbrott, SOU 2020:57, med förslaget att låta brott med hedersmotiv utgöra en egen brottsrubricering. För att utreda om det vore befogat att införa lagförslaget i brottsbalken analyseras det utifrån några utvalda principer och teorier för kriminalisering. Trots att heder är ett problematiskt och svårdefinierat begrepp kan några karaktäOn October 7, 2020 the investigation Ett särskilt hedersbrott, SOU 2020:57, was presented, with a proposal to let crimes with honor motives constitute a specific criminal provision. In order to investigate if it would be justified to introduce in the Penal Code, the proposal will be analyzed on the basis of some selected principles and theories for criminalization. Although honor is a problemati
The exponential-6 (exp-6) potential is an intermolecular pair potential that is widely used to model fluids at high densities. The path from molecular interaction to equation of state (EOS) for a gas is not straightforward however. Monte Carlo methods and molecular dynamics give accurate results but are too slow for demanding applications like detonation modelling or numerical simulations of react
In this thesis, we use Bloomberg data to compute a metric developed by Bhattacharya & Galpin (2011) to examine the popularity of value-weighting on the Swedish stock exchange. After analyzing our data, we reach three conclusions in documenting that: (1) Value- weighting is becoming more popular over time. (2) Value-weighting is more popular on the OMXS30 than on the market as a whole (the OMXS
Mesh networks are highly relevant and interesting today considering all the connected devices that exists. These devices often aim to have low power consumption to be able to be powered by smaller power sources such as solar cells or batteries. The hardware used by mesh networks often has the same purpose, to minimize power consumption. The purpose of this thesis is to provide an increased underst
The purpose of this report is to build on the knowledge of how parties facing poor election results make changes in their election manifesto. The case in question is the Swedish party Liberalerna, in English referred to as The Liberals. The empirical data that is used is two of the parties election manifestos from 2014 together with 2018. These are coded by Manifesto Project Database. Using three
The use of land in the Swedish city of Lund is a question that has attracted a lot of attention in the last couple of years. The city is in need of expansion but ideas of where and how to accomplish this has differed until the release of the latest general plan which dictates that all major developments should be realized by densification. The city is surrounded by high value farmland which needs
The effects of nitrogen (N) fertilization (0-150 kg N ha(-1) year(-1) since 1865) and pH (3.3-7.4) on fungal and bacterial growth, biomass and phospholipid fatty acid (PLFA) composition were investigated in grassland soils from the 'Park Grass Experiment', Rothamsted Research, UK. Bacterial growth decreased and fungal growth increased with lower pH, resulting in a 50-fold increase in the relative
Several previous studies have shown that floorball belongs to a high-risk group of sports in terms of eye injuries. Protective eyewear is available, but the extent of its use and impact on eye injuries are unknown. The purpose of this study was to investigate the current incidence of eye injuries caused by floorball and to compare it with the present use of protective eyewear. Medical records were
This cross-sectional case study investigates patterns of politicisation in election campaigns of the German Eurosceptic party Alternative für Deutschland (AfD) by means of a comparative multi-level analysis. It adds to the existing literature by examining the Eurosceptic elements of the party’s campaign communication across various decision-making levels. It examines EU issue salience, the dimensi
The increase of shrub extent in arid and semi-arid environments is reducing the species richness all over the globe. This process of shrub encroachment was found to result from changes in anthropogenic land use, especially from too high or too low grazing intensity. The Great Alvar on the island Öland, Sweden, is a unique grassland ecosystem with a high species richness. Changes in land use patte
