This thesis has been performed in the ethylene oxide plant at Akzo Nobel in Stenungsund. Ethylene oxide is an important ethylene based intermediary compound. The primary use for ethylene oxide is in the manufacture of derivatives such as ethylene glycol, surfactants and ethanolamine’s. In the production of ethylene oxide, ethylene and oxygen reacts over a silver catalyst surface. Mainly two react
Lipids are organic molecules vital for living organisms. They are part of cell membranes and provide an important energy reserve once they are digested by our body. They are most commonly known as fats and oils. Some important so-called polar lipids are amphiphilic molecules, which means they have a head group that is water ‘loving’ (hydrophilic) and a hydrocarbon tail is water ‘hating’ (hydrophobNonlamellar lipid liquid crystalline phases have many potential applications, such as for drug delivery, protein encapsulation or crystallization. Lipid liquid crystalline sponge phase (L3) has so far not been very much considered in these applications, in spite of apparent advantages in terms of its flexibility and capacity of forming large aqueous pores able to encapsulate large bioactive molecu
Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrost temperature change has been compiled. Here we use a global data set of permafrost temperature time series from the Global Terrestrial Network for Permafrost to evaluate temperature change across permafPermafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon.

Popular science summaryMycorrhizal associations Mycorrhizal fungi are organisms that live in association with plant roots and provide plants with water and nutrients in exchange for the sugars obtained during photosynthesis. In forested ecosystems mycorrhizal fungi are crucial for tree nutrition and trees rely heavily on these associations to take up key elements like nitrogen and phosphorus. As rHigh levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching.I studied a Norway spruce forest in a region of high N deposition in southwest Sweden and added N, P or N+P to force thesystem to N or P limitation. I studied tree
Although renovation costs can lead to rent increases in energy retrofitting, it is often assumed that reductions in energy costs will counterbalance the rent increase. In Swedish multifamily housing, energy costs for heating are however generally included as a fixed component in the monthly rent, meaning that the rent increase after energy retrofitting corresponds to the net change in rent level aAlthough renovation costs can lead to rent increases in energy retrofitting, it is often assumed that reductions in energy costs will counterbalance the rent increase.

Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. Evolution has therefore favoured the development of phenotypic plasticity in anti-predator defences.

Mexico has experienced the dramatic escalation of crime and violence in an organized form since the 1990s, and have also witnessed the highest number of homicides in the last ten years. It has adversely affected the national security, economic growth and social development with an especially detrimental effect on youth in Mexico. This study examines the direct and indirect impacts of drug trade-re
According to the curriculum of the preschool, one of it's purposes is to work with equality, and to challenge traditional gender roles. Despite this, many preschools still lack active work with gender/equality – the difference amongst pre-schools is sometimes extreme. I tried to find elements that influence preschool teachers to choose to work with gender and equality. Some of these elements a

Every year 125 000 tons of food is thrown away by Swedish grocery stores. A lot of this food is still eatable and this has caused people to go out at night to take the food for themselves straight from the dumpster. This is called dumpster diving. The purpose of this study has been to examine the discrepancy between the legal norms which proclaim it as illegal and the norms within the dumpster div

The binding site of immunoglobulin G (IgG) to herpes simplex virus (HSV) type 1-induced Fc receptor was investigated using human IgG Fc intermediate (Fc(i)) fragments, fragment D of staphylococcal protein A (SPA) and chemically modified human IgG. Human IgG Fc(i) fragment composed of one Cgamma2 and two Cgamma3 domains, bound strongly to HSV-1-infected cells. Fragment D, a monovalent subunit of SP
