Popular Abstract in Swedish Partiklar som finns i luften och som vi andas in kan leda till negativa hälsoeffekter bland oss människor. I varje andetag andas vi in tusentals partiklar som tar sig ner i våra luftvägar. Det är normalt. Våra kroppar har försvarsmekanismer som tar hand om och oskadliggör partiklar som vi andas in och som fastnar i våra andningsvägar. Vid för höga halter av partiklar i BACKGROUND: Exposure to airborne particles in occupational environments can lead to both acute and long-term health effects in humans. To date, particle exposure limits in the air are typically given in terms of mass concentrations. But by only using mass concentration to characterize particles means there is a risk that other relevant characteristics, such as particle size and composition are con

A method for preparation of thylakoids from plant leaves on a large scale is described. The method involves: 1) disruption of the cells with a blender followed by filtration to remove large cell debris and non disrupted cells. 2) precipitation of the thylakoids by adjusting the pH to the isoelectric point, pH 4.7. 3) a washing step by dilution of the precipitate in water followed by precipitation

Multiple sequence alignment is the foundation of many important applications in bioinformatics that aim at detecting functionally important regions, predicting protein structures, building phylogenetic trees etc. Although the automatic construction of a multiple sequence alignment for a set of remotely related sequences cause a very challenging and error-prone task, many downstream analyses still

Popular Abstract in Swedish Prosodi och intonation är viktiga delar i det mänskliga talet. I system för text-till-talomvandling och automatisk taligenkänning måste prosodiska modeller inkluderas för att uppnå acceptabla resultat. Denna avhandling bidrar till modelleringen av svensk prosodi ur lexikalt och akustiskt perspektiv. Tre aspekter av lexikal modellering av prosodi studeras. Vi skisserar Prosody and intonation are very important ingredients of human speech. In speech technology, text-to-speech (TTS) and automatic speech recognition (ASR) systems must incorporate prosodic models in order to reach acceptable performances. We contribute to the modelling of Swedish prosody in a speech technology context from lexical and acoustic angles. Three aspects of lexical prosodic modelling are

OBJECTIVE: Aortic aneurysm size is a critical determinant of the need for intervention, yet the maximal diameter will often vary depending on the modality and method of measurement. We aimed to define the relationship between commonly used computed tomography (CT) measurement techniques and those based on current reporting standards and to compare the values obtained with diameter measured using u

”De sociala perspektiven har först under senare år förts in i diskussionen, trots att människors beslut och beteenden är avgörande för socialt, ekologiskt och ekonomiskt hållbar utveckling” skriver Anna-Lisa Lindén, professor i sociologi, bland annat.

Physical activity is of great benefit to women treated for breast cancer and can even be vital. The aim of this qualitative study was to describe how women treated for breast cancer experience physical activity after surgery. Twelve women, strategically selected according to hospital, age and length of time since surgery, took part in a semi-structured interview. A qualitative method with a phenom
