Popular Abstract in Swedish Målsättningen i denna avhandling är att identifiera funktionen hos COMP (Cartilage Oligomeric Matrix Protein). Detta protein finns framförallt i brosk och sena. Dessa vävnader tillhör bindväven och har till funktion att ta upp och fördela belastning, utgöra ett skydd och förmedla transport av olika ämnen. De är uppbyggda av ett fåtal celler inbäddade i en dominerande exConnective tissues contain a prominent extracellular matrix that provides mechanical and physical properties. This extracellular matrix contains as a major constituent a network of collagen fibres. These are composed of collagen fibrils, which in turn are assembled from many collagen molecules aligned parallel to each other. Several proteins, e.g. collagens, leucine-rich repeat proteins and thromb

Popular Abstract in Swedish På de allra flesta arbetsplatser utsätts arbetstagarna för risker, och de kemiska hälsoriskerna utgör en omfattande del av dessa. Till exempel är det många som får astma orsakad av exponeringar i arbetsmiljön. En vanlig orsak till yrkesrelaterade luftvägsbesvär är exponering för isocyanater. Isocyanater är små reaktiva (instabila) ämnen som används i polymerindustrin föExposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. In the present study, we have determined the personal air and biomarker levels of isocyanates for a group of occupationally exposed workers (n=170) in different types of industrial processes. Also, the biomarker levels

When low calorific value gases are fired, the performance and stability of gas turbines may deteriorate due to a large amount of inertballast and changes in working fluid properties. Since it is rather rare to have custom-built gas turbines for low lower heating value (LHV) operation, the engine will be forced to operate outside its design envelope. This, in turn, poses limitations to usable fuel

Popular Abstract in Swedish Denna avhandling behandlar olika aspekter av den svenska föräldraförsäkringen. Avhandlingen inleds med ett översiktligt kapitel i vilket föräldraförsäkringens historia samt nyttjandet av föräldraförsäkringen under perioden 1993-2005 beskrivs. Därefter följer två studier som behandlar tillfällig föräldraledighet (för vård av sjukt barn) och en studie som behandlar föräldThis thesis contains an introductory chapter and three essays, all considering different aspects of the Swedish parental insurance. In the first two essays, different aspects of temporary parental leave (leave from work to take care of a sick child) are investigated, whereas the third essay considers parental leave (leave from work to take care of a new-born child). In the first essay, On the Sha

This study considers detection of polyproline type II secondary structures from protein sequences. This difficult problem was handled with multilayer perceptron neural networks, which were found to be useful for such bioinformatics studies. Polyproline II secondary structures have not previously been tried to be predicted from sequences.

When performing adaptive optics (AO) correction for the effect of atmospheric fluctuations, different effects, related to measuring the wavefront at one wavelength and observing at another one, may show up. Some of these effects are related to the dispersive properties of the atmosphere. Others are related to diffraction, both regarding light propagation through the turbulent atmosphere to the ent

The evaporative gas turbine (EvGT), also known as the humid air turbine (HAT) cycle, is a novel advanced gas turbine cycle that has attracted considerable interest for the last decade. This high-efficiency cycle shows the potential to be competitive with Diesel engines or combined cycles in small and intermediate scale plants for power production and/or cogeneration. A 0.6 MW natural gas-fired EvG
