Endotoxin was measured in air and dust samples collected during four commercial aircraft flights. Samples were analyzed for endotoxin biological activity using the Limulus assay. 3-hydroxy fatty acids (3-OH FA) of carbon chain lengths C10:0-C18:0 were determined in dust by gas chromatography-ion trap tandem mass spectrometry. The geometric mean (geometric standard deviation) endotoxin air level wa

Epidemiological studies have indicated a relationship between overweight and cardiovascular disease. The present investigation was undertaken to identify anthropometric variables in childhood which may reflect the risk of cardiovascular disease in terms of unfavourable changes in apolipoprotein and lipid concentrations. Twenty-nine obese 14-year-olds and 32 obese 12-year-olds were recruited from a

Popular Abstract in Swedish Syftet med avhandlingen är att presentera en sociologisk analys av en "religionsfrihetssituation". Den grupp som särskilt berörs i avhandlingen är den invandrarde muslimska minoriteten i Sverige, en grupp som har vuxit avsevärt under de senaste decennierna. Muslimerna har invandrat till ett samhälle som länge präglades av religiös enhet, men som idag har utvecklats tillThis dissertation deals with the religious liberty situation of the Muslim minority in Sweden. The Muslim minority has grown considerably in recent decades as a consequence of labour and refugee immigration of a large scale, which has caused a change in Swedish society from an etnically, culturally and religously homogeneous situation to one of a significant heterogeneity. Sweden's way from unity

Student speech production is an essential part of language learning in the foreign-language classroom. The students usually have few opportunities to use the language outside the classroom, which underscores the importance of making good use of the time spent in the classroom. Much research has shown that learner output is necessary, or at least facilitative, in language acquisition. This claim fo

Objectives: To describe and compare the consumption of dairy products in cohorts included in the European Prospective Investigation into-Cancer and Nutrition (EPIC). Methods: Data from single 24-hour dietary recall interviews collected through a highly standardised computer-based program (EPIC-SOFT) in 27 redefined centres in 10 European countries between 1995 and 2000. From a total random sample

A model based on the penetration theory has been developed to calculate the dynamic absorption rate of sulfur dioxide into a droplet of limestone slurry. The model includes both instantaneous equilibrium reactions and reactions with finite rates; limestone dissolution, sulfite oxidation, gypsum crystallization and the hydrolysis reaction of CO2. The model has been used to quantify the mass transfe

The effects of small roundabouts on emissions and fuel consumption were evaluated using the “car-following” method in a before/after study. The results showed that at a roundabout replacing a signalised junction, CO emissions decreased by 29%, NOx emissions by 21%, and fuel consumption by 28%. At roundabouts, replacing yield regulated junctions, CO emissions increased on average by 4%, NOx emissio

The NOx storage and reduction approach was applied on a full-scale engine rig under stationary operation. NOx reduction experiments were performed and a catalyst model developed and tested. The exhaust system was equipped with a bypass system. A NOx reduction of 25-53% was achieved. At low temperature, higher values were reached when the exhaust gas bypass was longer than the injection period.

Injectable bone substitutes (IBS) based on calcium phosphate (CaP) and/or calcium sulphate (CaS) are used as fillers in bone defects to stimulate bone integration and allow mechanical loading. Two types of IBS, IBS-1 is CaP+20%CaS and IBS-2 is CaS+40% hydroxyapatite, were investigated. The materials were injected into holes in the femur and tibia in rabbits. After 10 weeks the femora were subjecte

A method for determining transition matrices for inhomogeneous dielectric shells is presented. The source can be either inside or outside the shell. The method is based upon expansions of the electric and magnetic fields in vector spherical harmonics. The expansion coefficients in the shell satisfy a system of linear ordinary differential equations in the radial direction. The expansion coefficien

Nitro blue tetrazolium (NBT) is an artificial electron acceptor which has been suggested to be a useful tool in studies of free radicals. To establish whether NBT could be useful in morphological demonstration of free radicals in the retina, the staining pattern was examined in normal rat retina and after incubation with the free radical scavenger superoxide dismutase or with inhibitors of free ra

Popular Abstract in Swedish Avhandlingen tar avstamp i en pågående internationell diskussion om kvinnors mänskliga rättigheter och islam. I denna diskussion kan olika muslimska ståndpunkter identifieras. En del avvisar mänskliga rättigheter, såsom dessa formulerats i internationella människorättsdokument, som ”västerländska” påfund och hävdar de religiösa källornas överordnade auktoritet. För andrThe dissertation focuses on interpretations of Islam that claim compatibility with international human rights norms in the context of women’s rights. These interpretations are seen as parts of an on-going contemporary international debate on women’s human rights and Islam that engages Muslims as well as non-Muslims. Existing UN-formulated international human rights schemes are a basic starting poi

The current knowledge on lipoprotein secretion from the heart is examined in this article. The ability of cells to secrete apolipoprotein B (apo-B) containing lipoproteins depends on expression of the apo-B and microsomal triglyceride transfer protein (MTP) genes. Initially, it was shown that both genes are expressed in cardiac myocytes of mice and humans. Electron microscopy of human cardiac myoc

We present a new probability density function (PDF)-based computational model to simulate a homogeneous charge compression ignition (HCCI) engine with direct injection (DI) during gas exchange. This stochastic reactor model (SRM) accounts for the engine breathing process in addition to the closed-volume HCCI engine operation. A weighted-particle Monte Carlo method is used to solve the resulting PD

A new biologically active triterpenoid, favolon B (1), was isolated from fermentation broths of Mycena sp. strain 96180. Favolon B showed antifungal activities towards Botrytis cinerea, Mucor miehei, Paecilomyces variotii and Penicillium notatum. No activities were observed against bacteria and yeasts. The structure of favolon B was elucidated by spectroscopic techniques.
