Background: In Uganda, a previous study reported high HIV prevalence in persons with severe mental illness (SMI) compared to the general population, suggesting that persons with SMI might constitute a high-risk group for HIV. However, the study included first-time psychiatric admissions only, a group whose HIV prevalence may not reflect the prevalence in persons with SMI in general. We determined

This paper presents new experimental measurements of the laminar flame velocity of components of natural gas, methane, ethane, propane, and n-butane as well as of binary and tertiary mixtures of these compounds proposed as surrogates for natural gas. These measurements have been performed by the heat flux method using a newly built flat flame adiabatic burner at atmospheric pressure. The compositi

Risk disclosure is generally regarded as crucial in order for investors to make informed decisions in the resource allocation process. Our study is the first to empirically investigate the value-relevance of corporate risk disclosure. We focus on the disclosure of foreign exchange (FX) risk, which is an activity notorious for its lack of transparency. Our empirical analysis involves a FX risk disc

Background: Pro-inflammatory cytokines can affect intracellular lipid metabolism. A variety of effects have been described for different cell types; hepatocyte lipid turnover pathways are inhibited during inflammation, whereas interleukin-1 beta (IL-1 beta) reduces intracellular cholesterol levels in fibroblasts. Levels of the pro-inflammatory cytokines IL-1 beta and tumour necrosis factor-alpha (

InAs/GaSb nanowire heterostructures with thin GaInAs inserts were grown by MOVPE and characterized by electrical measurements and transmission electron microscopy. Down-scaling of the insert thickness was limited because of an observed sensitivity of GaSb nanowire growth to the presence of In. By employing growth interrupts in between the InAs and GaInAs growth steps it was possible to reach an in

In this paper, we develop a system for microphone selflocalization based on ambient sound, without any assumptions on the 3D locations of the microphones and sound sources. We aim at developing a system capable of dealing with multiple moving sound sources. We will show that this is possible given that there are instances where there are only one dominating sound source. In the first step of the s

Colorectal cancer (CRC) is one of the major causes of cancer globally. Recent studies proposed a role for cancer initiating cells (CICs), a small subset of replication-competent cells, in colon carcinogenesis. Although the role of inflammatory lipid-mediators in CRC progression is well known, their role in the promotion of cancer-initiating cells remains to be elucidated. For this thesis, we inves

High-pressure homogenizers (HPHs) are used to create sub-micron emulsions in low-viscosity fluids. As the flow in a real HPH is very extreme, with gaps ranging from 10 to 100 pm and high velocities, it is almost impossible to visualize the drop break-up process. In this study a plastic scale model of a HPH was made, allowing the visualization of drop deformation and break-up. Great care was taken

A critical review of Carlos Castaneda's work.

T lymphocytes are a critical cellular component of the adaptive immune response. They are generated in the thymus from bone marrow derived progenitors, where they undergo commitment to the T cell lineage and differentiate and mature into naïve CD4+ and CD8+ T cells. Naïve CD4+ and CD8+ T cells activation takes place in lymphoid organs after recognition of cognate antigen in the context of major hi

A new method for calibrating the hadron response of a segmented calorimeter is developed and successfully applied to beam test data. It is based on a principal component analysis of energy deposits in the calorimeter layers, exploiting longitudinal shower development information to improve the measured energy resolution. Corrections for invisible hadronic energy and energy lost in dead material in

A parasite's ability to be a specialist vs. a generalist may have consequences for its prevalence within one or more if its host species. In this study we investigated the relationship between host specialization and prevalence in the highly species diverse avian blood parasites of the genera Plasmodium and Haemoproteus. Contrary to trade-off hypotheses that may explain host specialization, within

Background: The teenage years are the years when adolescents seek their identity, and part of this involves experimenting with tobacco. The use of tobacco as such, and norms among their friends, is more important to the adolescents than the norms of parents when it comes to using tobacco or not. The aim was to explore the significance of using snus for adolescents, and attitudes to snus, as well a

The deswelling behavior of cross-linked DNA gels reports on DNA-cosolute interactions and gives a basis for the development of responsive DNA formulations. An investigation of the deswelling kinetics shows that an increase in the surfactant tail length gives a pronouncedly slower deswelling kinetics. In the same conditions, single stranded gels exhibited faster deswelling kinetics when compared wi

Sverige har ett mäktigt parlament, kanske det mäktigaste i den demokratiska världen. I avsaknad av alla de viktiga instrumenten för horisontell maktdelning har all offentlig makt samlats i riksdagen. Det är dock inte liktydigt med att de svenska riksdagsledamöterna är inflytelserika i motsvarande grad. I vad mån så är fallet bestäms av en rad faktorer, inte minst av valsystemet. Men också riksdage
