The propagation channel determines the fundamental basis of wireless communications, as well as the actual performance of practical systems. Therefore, having good channel models is a prerequisite for developing the next generation wireless systems. This thesis first investigates one of the main channel model building blocks, namely clusters. To understand the concept of clusters and channel chara

The importance of the nurse's role in the management of patients with type 2 diabetes has long since been emphasized. The aim of this study was to test the hypothesis that a structured organization of type 2 diabetes care, with a diabetes nurse working more independently of the general practitioner, has a significant impact on the patient's self-management and quality of care. The test consisted o

This study identifies teachers’ perceptions of requirements for including collaborations with the surrounding world in their teaching practice, with the aim of providing authentic and entrepreneurial learning environments for students. School management, time and teachers’ personal character traits and disposition were the most frequently stated areas of concern, followed by colleagues, surroundin

Here, we investigated the importance of hormone-sensitive lipase (HSL) as a retinyl ester hydrolase (REH). REH activity was measured in vitro using recombinant HSL and retinyl palmitate. The expression of retinoic acid (RA)-regulated genes and retinoid metabolites were measured in high-fat diet fed HSL-null mice using real-time quantitative PCR and triple-stage liquid chromatography/tandem mass sp

The purpose of this descriptive cohort study was to describe patients with hip fracture on the basis of ASA physical status and to identify preoperative risk factors associated with postoperative outcome up to 4 months after surgery. Data were collected prospectively through the Swedish National Hip Fracture and Anesthetic registers and retrospectively from medical and nursing records. The 428 pat

Sweden is frequently described both as one of the most advanced Western countries when it comes to social and economic equality, and as one of the most segregated with respect to gender and ethnicity. That kind of ambiguity leads to problems when discussing ways for immigrants to get entrance to the Swedish labour market and to get a permanent position at a Swedish workplace. In order to explore t

The vitamin A metabolite and transcriptional modulator retinoic acid (RA) is recognized as an important regulator of epithelial cell homeostasis in several tissues. Despite the known importance of the epithelial compartment of the thymus in T cell development and selection, the potential role of RA in the regulation of thymic cortical and medullary epithelial cell homeostasis has yet to be address
