Popular Abstract in Swedish Denna avhandling inom forskarutbildningsämnet arbetsmiljöteknik beskriver nyutvecklade provtagnings- och analysmetoder för att undersöka hur reaktionsbenägna luftföroreningar uppkommer och sprids i arbetsmiljön. Antalet människor som drabbas av allergier har ökat de senaste årtiondena. Många av de mekanismer som ger upphov till allergier och överkänslighetsreaktioner kMany sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds. Exposure can occur in many situations, not only at the workplace where the raw materials are handled. The f

The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. In this thesis, the properties of heavy rainfall in a 73 000 km2 area

The main purpose of the pursued research is to increase knowledge of the effects of knots in structural timber so that characteristics of weaker timber may be determined and applied to improve current grading techniques. In the process, a three-dimensional fiber paradigm was established, which describes variations of local principle material axes in timber containing knots. The adaptability of the

Popular Abstract in Swedish För att kunna simulera de fysikaliska fenomen som pågår i förbränning, krävs även en beskrivning av den kinetik som ingår i förbränningsprocessen. För detta ändamål utvecklas kinetiska modeller. En kinetisk modell är en lista med kemiska reaktioner och reaktionshastighetsparametrar. Modellernas tillämpningsområde begränsas av de valideringsfall och de fysikaliska parameThe simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. A software package, BlueBellMouse, has been developed to facilitate a deeper automatization and ease of simulation, reduction and optimization of kinetic models. A kinetic model is made of a list o

Popular Abstract in Swedish Det har blivit vanligt med beskrivningar av hur olika trender påverkar det sätt på vilket arbetslivet utformas. I första hand rör det sig om informationsteknikens inflytande inom i stort sett alla samhällsområden men det handlar också om en globaliserad ekonomi, ökad konkurrens, samt strävan efter högre kvalitet och större flexibilitet. Denna utveckling kan förstås som The study explores the interaction of general management ideas like TQM (here referred to as technocratic visions) and microprocesses of narrating and organizing in two different contexts: the public sector (health care) and the private sector (manufacturing) in Sweden. The purpose is to provide a better understanding of what happens when models of this type are introduced into a work organization

Milk is a dilute aqueous dispersion with a complex mixture of proteins, fat, carbohydrates, vitamins and minerals. Milk membrane lipids are a part of the milk fat globule membrane (MFGM), which covers the fat globules. During dairy processing membrane material is released and surface structure features are altered. The presence of free membrane material as well as various surfaces might influence

Popular Abstract in English Plant diseases are directly associated with food security because they result in severe reduction of plant yield and thus they add to the scarcity of foods in the world, which can lead to negative repercussions on humankind. Late blight disease that severely hit Ireland in 1840s, which was caused by Phytophthora infestans and is mentioned in the historical records as thAbstract The oomycete Phytophthora infestans, which causes the devastating late blight disease of potato, is notorious for developing resistance to conventional control strategies (fungicide application and resistance breeding by introgression of R gene). To increase our tool box of disease management strategies available to combat P. infestans, there is a need to explore several new approaches th

Popular Abstract in Swedish Den s.k. "uncertain dichotomous choice" modellen används för att beskriva gruppbeslut. Modellen består av två komponenter: gruppstruktur och röstsystem. Gruppen utgörs av ett antal personer med ett gemensamt mål. Medlemmarnas uppgift är att välja ett av de två givna alternativen, av vilka det ena är korrekt. Dessa två symmetriska alternativ antas så utformade att det inA probabilistic framework used in studying collective decision making is the uncertain dichotomous choice model. The model is essentially characterized by two components: the organizational structure and the voting process. By organizational structure, we refer to a group composed of members with common objectives and who are tasked to choose one of the two given alternatives, one of which is assu

Popular Abstract in Swedish Hormonerna vasopressin och oxytocin frisätts från hypofysens baklob. Hypofysen är en körtel, som är belägen på undersidan av hjärnan och utsöndrar en rad olika hormoner vilka i sin tur påverkar och reglerar aktiviteten i en mängd andra organ. Vasopressin medverkar till regleringen av vatten- och saltbalansen i kroppen, men verkar också sammandragande på icke-viljestyrdVasopressin and oxytocin seem to have pivotal roles in the pathophysiology of primary dysmenorrhoea and preterm labour. Prostaglandins are also involved in the regulation of uterine activity with different receptors mediating both stimulation and relaxation. We explored different aspects of synthesis, release and receptor pharmacology of vasopressin and oxytocin. We also tested a vasopressin and o

Popular Abstract in Swedish Vår egen tid kännetecknas av ett mycket stort intresse för Förintelsen, det vill säga nazisternas folkmord på Europas judar. Denna bok försöker skissera några viktiga aspekter av den kulturella förståelsen av Förintelsen, genom att studera hur den avbildats i visuell kultur. Med "visuell kultur" förstås ett brett spektrum av kulturella uttryck, från dokumentär- och presThis thesis examines the representation in visual culture of the Holocaust, the Nazi genocide of European Jewry. It is divided into three main parts, each one focusing on a particular aspect of Holocaust representation. Part 1, "Meaning" (chapter 1-3), begins by considering the important role played by documentary photographs from the concentration camps for the public knowledge and conception of

The savanna ecosystem is one of the most dominant and complex terrestrial biomes, deriving from a distinct vegetative surface comprised of co-dominant tree and grass populations. While these two vegetation types co-exist functionally, demographically they are not static but are dynamically changing in response to environmental forces such as annual fire events and rainfall variability. Modelling s

Abstract:This doctoral thesis is addresses two topics in integrated circuit design: multiband direct conversion cellular receivers for cellular frequencies and beam steering transmitters for millimeter wave communication for the cellular backhaul. The trend towards cellular terminals supporting ever more different frequency bands has resulted in complex radio frontends with a large number of RF in

We evaluate the capability of the global atmospheric transport model TM5 to simulate the boundary layer dynamics and associated variability of trace gases close to the surface, using radon (222Rn). Focusing on the European scale, we compare the boundary layer height (BLH) in the TM5 model with observations from the National Oceanic and Atmospheric Admnistration (NOAA) Integrated Global Radiosonde

The forces of globalization and the enabling characteristics of internet communication have impacted the nature of research and innovation.
