The thesis work was performed with the aim of increasing knowledge and understanding of the combustion of oxygenated fuels and intermediates. This was accomplished in two steps: experimental measurements of the laminar burning velocity to expand current databases and development of a reaction mechanism. In the first part of the project, the laminar burning velocity of oxygenated fuels and interme

My thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. In laboratory experiments enchytraeids reacted to chemical stress with

The aim of this thesis was to explore some of the important links between waterfowl and the biota in shallow eutrophic lakes in temperate areas. Waterfowl depend on macroinvertebrates as sources of protein and calcium, which are essential for egg production and growth. Macroinvertebrates in turn depend on submerged vegetation for food and shelter. Increased density of vegetation thus leads to incr

This paper presents and suggests a load combination factor for moisture induced stress (MIS) when MIS and snow load are combined. It is argued that MIS may be considered as an ordinary load to be combined with other structural actions, for example snow load. This outlook is not new but till now the load combination factor issue has not been investigated. Based on measured snow depths and calculate

Among policy-makers in Europe the modal shift - a shift från polluting modes of freight transport to less polluting modes - has been a popular suggestion for reducing CO2-emissions of transportation. In particular, intermodal road-rail solutions, where a combination of road and rail transport is utilized to move trailers and containers, have been stressed as an important measure to reach de desire

The gastrointestinal tract of the foetus is considered sterile but during vaginal birth the neonate comes into contact with bacteria from the maternal vaginal and intestinal microbiota. The main focus of this doctoral thesis was to elucidate the initial bacterial ecosystem in newborns and to relate microbial perturbations to physiological traits. The bacterial flora was mainly studied with molecul

Proteins are complex structures and years of research have been spent on attempts to understand their complexity. The non-covalent interactions involved in protein folding are: hydrophobic effect, electrostatic interactions, van der Waals interactions and hydrogen bonding. It has been of great interest to address the importance of each of those interactions in proteins. While hydrophobic effect is

The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. The use of biomass gasification for energy purposes can help lower the net emissions of greenhouse gases,

Trots att forskningen kring transpersoner har ökat exponentiellt de senaste decennierna så vet vi fortfarande lite om den könsbekräftande vården utanför samhällets dominerande institutioner. Utifrån gruppintervjuer och självbiografiska inslag möjliggör denna uppsats en ökad förståelse för de som utför hormonbehandlingar utanför det officiella vårdsystemet. Uppsatsen fokuserar främst på hur den sve

I en jämförelse mellan det skriftliga och det arkeologiska materialet framträder en bild av medeltida tegelbruk i allmänhet och det medeltida tegelbruket vid S:t Mikael i synnerhet. Arkeologiskt iakttagbara anläggningar vid ett medeltida tegelbruk, förutom en tegelugn är följande; lertag i form av gropar eller stora gravar (eventuellt vattenfyllda), vallar efter leran som lagts till vintring, gropWhen, why and how the brick-making tradition started in the Nordic countries is well known. However, research on the spatiality and layout of the the production of bricks in medieval times is lacking. What archaeologically observable sites, apart from a kiln, were part of a medieval brickyard and how were they organized? In a comparison between written material on brick production and archaeologic

Spelreklam utgör idag en majoritet av all marknadsföring som sker. Måttfullhetskravet i spellagen utgör ett krav att spelaktörer ska iaktta måttfullhet vid marknadsföring av spel till konsumenter. Måtfullhetskravet har idag en vägledning som innebär rekommendationer och riktlinjer. Måttfullhetskravet ska förbli flexibelt i spellagen och vid sanktioner ska en helhetsbedömning göras. Detta lämnar 15Gambling advertising today constitutes a majority of all marketing that takes place. The requirement of moderation in the Gambling Act is a requirement that gambling players must observe moderation when marketing games to consumers. The requirement of moderation today has a guide that entails recommendations and marketing guidelines. The moderation requirements must remain flexible in the Gambl

Cykeln är en avgörandefaktor för en uppnå en samhällseffektiv och långsiktigt hållbar transportförsörjning där en mer attraktiv cykelinfrastruktur kan ge upphov till att fler väljer att resa med cykel i stället för bil. Överflyttningseffekterna från biltrafiken skulle innebära en reduktion av avgasutsläpp, icke-avgaspartiklar från vägtrafik, bulleremissioner och mindre trängsel i staden. SamtidigtBicycles are a prerequisite for a long term sustainable transportation service, where a more attractive infrastructure would contribute to a more sustainable transport mode such as cycling in favour of using motor vehicles. Success in changing the main mode of travel from cars to bicycles would result in reduction of greenhouse gas and exhaust emissions, non-exhaust emissions, noise pollution and

Det centrala för denna uppsats är att ur ett borgenärsinriktat perspektiv utreda två alternativ för rekonstruktion av företag; företagsrekonstruktion genom FrekL och rekonstruktion genom konkurs. FrekL är en tämligen ny lag i den svenska insolvensrätten. Tidigare rekonstruktioner av företag skedde så gott som alltid genom konkurs, även om AckL fanns som alternativ. FrekL var bland annat tänkt lik
