The need for red blood cells to transport oxygen and CO2, blood platelets to stop bleedings, and neutrophils, macrophages, B- and T-cells for host defense, is a prerequisite for life. These mature blood cells have a limited life span and are thus constantly replenished by an enormous cell production (estimated to 1012 cells per day) which primarily takes place in the bone marrow (BM). Mature blood
The present study was designed to describe the pattern of long-term formal support received by people with mental disorders, and to investigate the relationship between the medical, psychological and social characteristics of the participants and types of formal support. This study is based on a cohort (n = 192) of people born in 1902 and 1903 in a community in Southern Sweden. The research partic
Popular Abstract in Swedish De senaste 150 åren har erbjudit en dramatisk utveckling av vår förmåga att sprida både njutningar och smärta, både i form av upptäckter av ämnen såsom TNT och dynamit och framställningen av heroin och Viagra. Denna utveckling har följts av teknologiska framsteg som tillåter studier av dessa kemikalier genom deras interaktion med till exempel radiosignaler eller laser. Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic tech

During the last few decades there have been speculations as to whether heavy drug abuse among youths has increased. The aim of this thesis was to examine the heavy drug addiction amongst clients between the ages of 19 and 27 who have come in contact with the adults unit at Södermalms stadsdelsförvaltning (Stockholm, Sweden) in the time period between 2002-2010. What has the development for these y
Abstract Increasing the share of renewable energy for covering our energy demand is central to the energy policy of the European Union. Despite the acknowledged importance, renewable energy has not yet reached the favoured wide-spread utilisation throughout Europe. Wood pellets, cylindrical sticks of 10 to 30 mm length mainly made from wood processing residues, are a renewable, cost-competitive, l
During the last ten years several international studies and reports have paid attention to the sexual life of HIV-positive homosexual men, while in Sweden this area is unexplored and has to be investigated in the future. The lack of knowledge of the sexual life of HIV-positive homosexual men risks to stigmatize still more this group of people who are already exposed in society. The aim of the repo
Anterior cord herniation is due to a ventral displacement of the spinal cord through a defect in the dura and/or arachnoid.1 Though the condition is rare, some case reports are available.1-3 The neurological symptoms can slowly deteriorate over several years.3 A Brown-Séquard-like syndrome is the most common presenting neurological finding.2,4 Asymptomatic cases may be discovered incidentally.4 Ho
The oceanographic conditions in the high-latitude North Atlantic ocean during the Holocene were reconstructed through analyses of sea surface temperature (SST; alkenone unsaturation ratios) and ice rafting (mineralogy and grain size) from two sediment sequences, one recovered from the Reykjanes Ridge at 59degreesN and the other from the Norwegian Sea at 68degreesN. Comparison of our records to pub
Lignin, a structurally intricate and heterogeneous phenolic biopolymer, holds considerable promise as a sustainable alternative to petrochemical-derived materials across diverse applications in the energy and materials sectors. However, precise lignin molecular weight and structure determination remains challenging due to its intrinsic tendency to aggregate in solution and the absence of chem
We present extensive density-functional theory (DFT) based calculations of the clean Rh(111) surface and of CO/Rh(111) overlayer systems. We study both ground-state structural properties and core-level shifts from differences in total energies at different coverages and adsorption sites. Most results are obtained using using norm-conserving or ultrasoft pseudopotentials. The overall reliability of
Unemployment and precarity have become key features of 21st century work. Employability is presented as a solution to these issues. Individuals are exhorted to manage their employability, in order to be able to exercise choice in the labour market. While employability is individualsʼ responsibility, governments, employers and educational bodies simply provide opportunities for its development. Hig
Abstract: Our aim is to study trends in mental ill-health and socioeconomic-related mental health inequalities over time in Sweden. We also make a first attempt at disentangling why we see such a development, by decomposing any changes in terms of changes in selected demographic and socioeconomic characteristics among the population. A secondary aim is to consider how different indicators for mentAbstract: Our aim is to study trends in mental ill-health and socioeconomic-related mental health inequalities over time in Sweden.

Modern cities are often perceived as the antithesis of nature; the built environment is understood as the transformation of raw and untamed nature into a rationalized human landscape. However, a variety of scholars since the nineteenth century have noted the persistence of nature in cities, not only in providing essential services but also resisting human control. Most recently, urban geographers
Marginalised agrarian societies are suggested to be the most vulnerable to environmental hazards and other perturbations. There are competing explanations for this phenomenon, which include: a lack of development, global environmental change, and the development process itself, or capitalism more specifically. All three causal arguments are compelling, but typically offer only partial explanations
In silico tools for splicing defect prediction have a key role to assess the impact of variants of uncertain significance. Our aim was to evaluate the performance of a set of commonly used splicing in silico tools comparing the predictions against RNA in vitro results. This was done for natural splice sites of clinically relevant genes in hereditary breast/ovarian cancer (HBOC) and Lynch syndrome.
Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. This leads to major uncertainties in Holocene solar reconstructions. This PhD project aims to improve the Holoc
Various concepts guide discussions on global literature, not least ›transnational‹. The presenttext advocates, however, for the term trans-imperial, as offering a more correct definitionof world literature, or global literature, both in pre-modern and modern times. Imperialspheres build up worlds of strong interconnections, and the languages they employ becomeprivileged languages that may last bey
En privatperson eller ett företag som vill köpa försäkring kan vända sig till en försäkringsförmedlare för att få hjälp med att hitta lämpligt försäkringsskydd. Försäkringstagare befinner sig ofta i ett kunskapsmässigt underläge i förhållande till försäkringsförmedlare och det är därför viktigt att det ställs krav på försäkringsförmedlare. Det är dock viktigt att de krav som ställs är tydliga, så An individual or a company that wants to purchase insurance can turn to an insurance broker to acquire an adequate insurance coverage. Since the policyholder often holds less knowledge relative the insurance broker, it is important that there are requirements on insurance brokers’ role as a consultant. The requirements must however be explicit, in order for insurance brokers to be able to follow t
The marine ecosystem in the Baltic Sea is affected by multiple stress factors, e.g. eutrophication and deoxygenation, overfishing and anthropogenic pollution. Here we evaluate the short-term trends of dissolved oxygen in bottom waters and changes in the primary productivity within a coastal inlet in the Baltic Sea. Undisturbed sediment cores (mean sedimentation rate 0.5 cm yr-1) were retrieved fro
