This book attempts to answer the question of how it is possible that Christianity in the beginning of the second century C.E. had developed into a non-Jewish, Gentile religion. Since Christianity was originally one of many Jewish factions within the diversified Judaism of the period, and one that even primarily seems to have directed its attention to the people of Israel, the problem of its separa

The crystalline properties of starch constitutes a puzzling area of research. Our understanding of the crystalline structure of amylopectin, that is the crystalline component in starch, is based on the observations from investigations on modified amylose. The first part of this thesis includes a discussion of the unit cells (the smallest crystalline units) suggested in the literature. The differen

A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. hydrogen gas) by splitting water molecules. However, i

The modification of drugs into pro-drugs is an attractive concept allowing you to tweak the chemical and physical properties of a drug without changing the original structure of the active compound. In principle, any compound possessing a preferred biological activity can be transformed into a pro-drug. Many natural products harbor qualities that are potentially interesting as drugs but difficult

Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy. However, there is widespread concern that current quality assurance practices hav

The studies presented in Papers I to VI illustrate several different aspects of the impact of vascular plants on methane emissions from northern natural wetlands. The subject has been approached on different scales, ranging from the study of microbial substrates in the vicinity of a single plant root, to an attempt to extrapolate some of the results to the entire northern hemisphere north of 50°N.

The studies presented in this thesis concern the optimisation and evaluation of the dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) technique for the assessment of perfusion-related parameters of the brain, such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT). Several methodological factors influence these measurements, for example, contra

Synthesis of compounds based on the structurally rigid bicyclo[2.2.2]octane and the dibenzobicyclo[3.3.1]nonane frameworks and also their application as ligands and catalysts in asymmetric synthesis are described. For the synthesis of 1,3-diols based on the bicyclo[2.2.2]octane framework, an improved synthesis of the starting material bicyclo[2.2.2]octan-2,6-dione was developed and performed at 0

The migratory behaviour of birds has received much scientific interest, though many questions still remain unsolved. One of the reasons for this is the difficulty of following the birds as they move between breeding and wintering localities. Populations may mix on migration and the origin of individual birds is difficult to assess. One way to address this problem may be to develop genetic populati

During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. By recovering the aroma complex from fresh juice and then adding it back to the processed juice, heat treatment can be avoided. Hydrophobic pervaporation is an emerging membr

What are the discursive pre-conditions for planning? In this dissertation the author analyzes and critically assesses the assumptions which underlie our thinking about planning. This is done in an analysis of firstly, how planning is legitimized, and secondly, what consequences these forms of legitimation have for planning theory as well as for planning as a political practice. The author descri

The subject of this study is the re-construction of German national identity and nationalist thinking within the framework of the 1990s’ history discourse in relation to the Nazi past and the Holocaust. The empirical focus is on national politics and the press. Maurice Halbwachs’ social constructionist theory on collective memory and Jan Assmann’s thesis on the defining power of elites in the cult

This thesis focuses on the electromagnetic design of a synchronous machine suited for a belt-driven alternator and starter (BAS) in a micro hybridisation of a mid-size passenger car. The BAS needs to provide a high cranking torque to start the combustion engine, especially in a cool condition where the requirements are highest. Besides the high cranking torque it is desirable to have high power pe

The aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. Biomarkers of TDI and MDI were determined as the corresponding amines, toluenediamine (TDA) and methyle

A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. Two telescopes have been used with an average angle towards the photon beam of 70 and 110 degrees. The silicon strip detectors have been us

Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. Single clinical electron and photon beams were evaluated and gel dose distributions were mainly w

In the era of privatization and securitization, private security companies are becoming a more important actor for ensuring safety in a society felt increasingly unsafe. Ensuring safety has been seen as a fundamental task of the state, which is now transferring to the private sector. This study examines one of Sweden's private security companies. Do they consider themselves as having a social
