PURPOSE: The objectives of this study are: (1) to investigate the dosimetric differences of the different treatment planning systems (TPS) in breast irradiation with tangential fields, and (2) to study the effect of beam characteristics on dose distributions in tangential breast irradiation with 6 MV linear accelerators from different manufacturers. METHODS AND MATERIALS: Nine commercial and two u
Background. The lipopolysaccharide of Helicobacter pylori plays an important role in colonization and pathogenicity. The present study sought to compare structural and biological features of lipopolysaccharides from gastric and enterohepatic Helicobacter spp. not previously characterized.Materials and methods. Purified lipopolysaccharides from four gastric Helicobacter spp. (H. pylori, Helicobacte
Pneumonia is a form of lung infection that may be caused by various micro-organisms. The predominant site of infection in pneumonia is debatable. Advances in the fields of diagnostic and therapeutic medicine have had a less than optimal effect on the outcome of pneumonia and one of the many causes is likely to be inadequate antimicrobial concentrations at the site of infection in lung tissue. Trad
Understanding, monitoring and mitigating drought is a very difficult task as a consequence of the intrinsic nature of the phenomenon. In addition, assessing the impact of drought on ecosystems and societies is also a complex task, because the same drought severity may have different consequences in different regions and systems due to the underlying vulnerabilities. New technologies based on geosp
An imbalance of the trace element status in human tissues and body fluids has been suggested as a contributing factor for the development of fibromyalgia (FM). The study comprised 38 females with defined fibrornyalgia (FM) according to generally accepted criteria from the American College of Rheumatology (ACR). They were compared with 41 females matched for age and Geographic location. The concent
Preparation of a minimum PSII core complex from spinach is described, containing four Mn per reaction center (RC) and exhibiting high O2 evolving activity [~4000 mol of O2 (mg of chl)-1 h-1]. The complex consists of the CP47 and CP43 chlorophyll binding proteins, the RC D1/D2 pair, the cytochrome b559 subunits, and the Mn-stabilizing psbO (33 kDa) protein, all present in the same stoichiometric am
C4b-binding protein (C4BP) is a potent inhibitor of the classical pathway of the complement system. This large plasma glycoprotein consists of seven identical a- chains and a unique b-chain held together by disulphide bridges. Both types of subunits are composed almost exclusively of complement control protein domains (CCPs). Using homology-based computer modelling and mutagenesis of recombinant p

Lysine-specific chemical crosslinking in combination with mass spectrometry is emerging as a tool for the structural characterization of protein complexes and protein-protein interactions. After tryptic digestion of crosslinked proteins there are thousands of peptides amenable to MSMS, of which only very few are crosslinked peptides of interest. Here we describe how the advantage offered by off-li
Feedback with carry shift registers (FCSRs) have previously been available in two configurations, the Fibonacci and Galois architectures. Recently, a generalized and unifying FCSR structure and theory was presented. The new ring FCSR model repairs some weaknesses of the older architectures. Most notably, the carry cell bias property that was exploited for an attack on the eSTREAM final portfolio c
Genome-wide association studies (GWASs) have identified several single-nucleotide polymorphisms (SNPs) influencing the risk of Hodgkin's lymphoma (HL) and demonstrated the association of common genetic variation for this type of cancer. Such evidence for inherited genetic risk is also provided by the family history and the very high concordance between monozygotic twins. However, little is known a
Popular Abstract in Swedish Den här avhandlingen behandlar unionens statsstödskontroll och dess tillämpning på statliga stöd till banker. Den huvudsakliga problemställningen i avhandlingen berör vilka villkor som måste vara uppfyllda för att bankstöd ska kunna förklaras förenliga med den gemensamma markanden, enligt unionens statsstödskontroll i artikel 107 3 FEUF. Avhandlingen behandlar alla bankThis thesis examines the state aid rules of the European Union and the application of these rules on banks. The primary problem that is addressed is what conditions should be fulfilled in order for state aid to banks to be declared compatible with the Common Market according to article 107 3 FEUF. The thesis addresses all kinds of state aid to banks and these have been divided into the following g
Emissions of greenhouse gases in all sectors of society must reach near zero, in developed countries preferably by 2050, in order to reach climate policy objectives. Alternatives and strategies for the energy and transport sectors are relatively well understood but the basic industries are often overlooked, not least in sustainability transition and innovation system studies. The policy and techn
European renewable energy policy has gone through a remarkable development over the last few years. It has moved from being a predominantly national-level concern with a focus on environmental issues to a top European policy agenda item where security of supply and competitiveness concerns figure with equal prominence. In 2007 and 2008 EU established a very forceful policy framework with ambitiou
To be able to survive in the long run the medical device industry of today needs effective development processes and ways to secure quality. These development processes and quality assurance processes must follow the different laws and regulations over the world depending on what market the organisations are established on. Organisations have been developing medical devices and systems over many y
The purpose of this study was to evaluate lesion conspicuity achieved with five different iterative reconstruction techniques from four CT vendors at three different dose levels. Comparisons were made of iterative algorithm and filtered back projection (FBP) among and within systems. An anthropomorphic liver phantom was examined with four CT systems, each from a different vendor. CTDIvol levels of
Popular Abstract in Swedish Under de senaste åren har nödvändigheten att ta hänsyn till utsatta grupper i den svenska befolkningen och deras varierande behov lyfts fram i rapporter och utredningar om utformningen av vård och rehabilitering av äldre. En sådan utsatt grupp är äldre teckenspråkliga döva.

This thesis contributes to filling this knowledge gap. The overarching aim was to gain further understanding and to increase the knowledge about quality of life, in terms of subjective wellbeing and health, activity and social contacts, among older deaf sign language users.
