Popular Abstract in Swedish Denna avhandling utforskar och analyserar segregation och självsortering i utbildning. Den syftar till att diskutera hur detta relateras till genus, individualisering och unga mäns och kvinnors positioneringar i lokala praktiker, genom val av gymnasieutbildning. Den fokuserar hur unga män och kvinnor hanterar och anpssar sig till det förändrade senmoderna samhället. AvThis thesis explores and analyzes segregation and self-sorting in education. It aims at discussing how this relates to gender, individualization and young men and women's positionings in local practices, through choices of upper secondary school education. It focuses on how young men and women cope with and adapt to the changing society in late modernity. The thesis is based on three empirical st

Simultaneous OH- and formaldehyde planar-LIF measurements have been performed in an optical engine using two laser sources working on 283 and 355 nm, respectively. The measurements were performed in a light- duty diesel engine, using n-heptane as fuel, converted to single- cylinder operation and modified for optical access. It was also equipped with a direct-injection, common-rail system as well a

This paper is built upon recognizing the need that digital forensic investigators are required in many cases to investigate, understand and report on all kind of cyber-crime including novel security breaches which have not been performed in the past. When an investigator is faced with the challenge to explore a new threat, we argue that the inquiry dynamics do not differ from an organisational emp

For Marx, technologies are either tools or machines and both are physical things. He was interested in the study of their intrinsic labor value in the capitalist production process. He recognizes that the life of a machine depends first on two physical factors: 1) erosion by use and 2) corrosion by abandonment: However, Marx recognizes also a third “moral” factor that depreciates the productivity

The quest of developing the logistics discipline, with a more theoretical foundation, is something several authors have emphasized and called for. Today one could argue that most of the research on logistics has a strong connection to the positivistic paradigm where there is a great emphasis on prediction, rationality and control in the solutions produced. In order to challenge the common assumpti

In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. In addition, the thesis deals with the basic development of large-area double barrier resonant tunneling diodes, as a st

The importance of carbohydrates in biological systems has become evident during the last fifty years. It is well known that pathogenic bacteria and viruses attach to glycoconjugates present at mammalian cell surfaces, and that this attachment is a prerequisite for the later stages of infection. Obviously, this interaction is interesting as a target for the development of novel ways to treat bacter

Popular Abstract in Swedish Hydrosilyleringsreaktionen är formellt en addition av en hydrosilan till ett omättat system. Reaktionen är oftast katalyserad av en övergångsmetall, och i denna process är det möjligt att påverka på vilket sätt additionen sker. Denna avhandling är en sammanfattning av fyra artiklar som behandlar regio-, stereo- och kemoselektivitet vid addition av hydrosilaner till konjThis thesis is a summary of four papers concerning various aspects on the transition metal catalysed hydrosilylation of 1,3-dienes. The hydrosilylation reaction is formally an addition of a hydrosilane to an unsaturated system and depending on the reaction conditions, control of stereo-, regio-, and chemo-selectivity can be achieved. Optically active heterobidentate P,N ligands were synthesised f

Duchenne muscular dystrophy (DMD) is a severe neuromuscular disorder, and one of the most frequently encountered, but one for which there is as yet no treatment. Laminin-111 protein therapy was recently shown to be a promising approach to prevent muscle disease in the mdx mouse model of DMD. The present study demonstrated that transgenic expression of laminin α1 chain in mdx animals, resulting in

The responses of the benthic marine dinoflagellate Prorocentrum lima to nutrient stress induced by unbalanced N:P ratios were the subject of this study. Batch cultures of P. lima cells were grown under NP sufficient (N as nitrate and ammonium) and deficient conditions, and the cell growth and toxicity were followed for eight weeks. P. lima grew slowly in all nutrient conditions and net growth rate

This work investigates the predictability of seasonal to inter-annual streamflow over several river basins in Norway through the use of multi-model ensembles. As general circulation models (GCMs) do not explicitly simulate streamflow, a statistical link is made between GCM-forecast fields generated in December and average streamflow in the melting season May-June. By using the Climate Predictabili

Nager A, Szulkin R, Johansson S-E, Johansson L-M, Sundquist K. High lifelong relapse rate of psychiatric disorders among women with postpartum psychosis. Nord J Psychiatry 2013;67:53-58. Background: The relapse rate for psychiatric disorders after postpartum psychosis is high. Apart from subsequent puerperal periods, previous studies have not examined when relapses in psychiatric disorders occur.

Abstract Objective. Periodontal ligament (PDL) cells produce IL-6 upon stimulation with inflammation promoters, but the signaling pathways involved have not been characterized. This study investigates underlying mechanisms behind regulation of PDL cell IL-6 production by E. coli and P. gingivalis LPS. Materials and methods: Human PDL cells, endothelial cells and monocytes were stimulated with E. c

Type and duration of fetal asphyxial insult affect the distribution of blood flow to the heart and brain. The purpose of this study was to describe dynamic and quantitative changes in regional myocardial and cerebral blood flow (CBF) during fetal asphyxia induced by total occlusion of the umbilical cord. Eleven exteriorized fetal sheep were subjected to total umbilical cord occlusion and five feta

We investigated patterns of isozyme variation and the hierarchic structure of genetic diversity in 25 Scandinavian populations of the lilioid herb, Anthericum liliago. Isozyme data suggest that tetraploid A. liliago has an allopolyploid origin and that A. ramosum may be one of its diploid progenitors. Two populations contained known or suspected hybrids between A. liliago and A. ramosum. Isozymes

A revised geometric representative model of the lower part of the colon, including the rectum, the urinary bladder and prostate, is proposed for use in the calculation of absorbed dose from injected radiopharmaceuticals. The lower segment of the sigmoid colon as described in the 1987 Oak Ridge National Laboratory mathematical phantoms does not accurately represent the combined urinary bladder/rect
