A review of the current evidence for internal fixation versus hemiarthroplasty versus primary total hip arthroplasty for displaced femoral neck fractures was undertaken. At the meta-analysis level no difference in postoperative pain, function, or quality of life can yet be demonstrated. A significant difference in mortality has also not been found, but a trend towards higher mortality after primar

The capacity to learn and reproduce vocal sounds has evolved in phylogenetically distant tetrapod lineages. Vocal learners in all these lineages express similar neural circuitry and genetic factors when perceiving, processing, and reproducing vocalization, suggesting that brain pathways for vocal learning evolved within strong constraints from a common ancestor, potentially fish. We hypothesize th

The use of Islamic symbols in metal music has, until now, been a rare phenomenon. A few years ago, some black metal-bands in Istanbul started using Islamic symbols in both their artwork and lyrics, often in an anti-Islamic fashion. Although research on metal music is well established, little has been done on the relationship between black metal and Islam. This thesis explores the relationship betw

Vi studerar blod- och immunsystemet och dess sjukdomar. Ett särskilt fokusområde är hur medfödd genetisk variation påverkar hur blod- och immunceller, och hur sådan variation kan utnyttjas kliniskt. Vilka gener och genmutationer styr t ex risken för blodcancer? Kan vi utnyttja dem för att förebygga och behandla? Vilka styr vår blodgruppsuppsättning? Kan vi utnyttja dem för säkrare transfusion? EttWe study the blood and immune system and its diseases. A particular focus area is how congenital genetic variation affects blood and immune cells, and how such variation can be utilized clinically. Which genes and gene mutations control, for example, the risk of blood cancer? Can we use them to prevent and treat? Who controls our blood group set? Can we use them for safer transfusion? Another impo

Sensors used for control have become widespread in water resources recovery facilities during the strive for resource efficient operations. However, their accuracy is reliant on uncertain laboratory measurements, which are used for calibration and, in turn, to correct for sensor drift. At the same time, current sensor calibration practices are lacking clear theoretical understanding of how measure

Occasional fog is a critical water source utilised by plants and animals in the Namib Desert. Fog basking beetles (Onymacris unguicularis, Tenebrionidae) and Namib dune bushman grass (Stipagrostris sabulicola, Poaceae) collect water directly from the fog. While the beetles position themselves optimally for fog water collection on dune ridges, the grass occurs predominantly at the dune base where l

Objectives: In this thesis we studied the performance of active extension portfolios constructed by using momentum/contrarian strategies. Fundamentally, the difference between the 130/30 and the long-only asset classes is the relaxation from the long-only constraint. The main implication of this study is to find out whether the 130/30 strategy is value adding, in comparison to other actively manag

In astrophysics, the ‘Goldilocks Zone’ describes the circumstellar habitable zone, in which planets, sufficiently similar to Earth, could support human life. The children’s story of Goldilocks and the Three Bears, one of the most popular fairy tales in the English language, uses this metaphor to describe conditions for life that are neither too hot nor too cold and neither too close to the sun nor

This article compares the articulation of dental stops by two subjects, one Swedish and one British English. The articulations are studied on X-ray motion films and the spectral consequences are studied on spectrograms. Speakers of Swedish are very conscious of a difference in pronunciation of dental stops and hear it as a typical part of an English accent in Swedish. The traditional Swedish expla
