Porträtterad nöd - berättelser om hemlösa

The Swedish welfare state has undergone structural changes in the last few decades, involving various cutback programmes and the decentralization of public service to the municipalities, with a shift from universal to more means-tested rights. Some of the responsibility for service to the very poorest people has been passed on to the family, the market and voluntary organizations. This has been pa

Why chloroplasts and mitochondria contain genomes

Chloroplasts and mitochondria originated as bacterial symbionts. The larger, host cells acquired genetic information from their prokaryotic guests by lateral gene transfer. The prokaryotically-derived genes of the eukaryotic cell nucleus now function to encode the great majority of chloroplast and mitochondrial proteins, as well as many proteins of the nucleus and cytosol. Genes are copied and mov

Classification of Electrocardiographic P-wave Morphology

The atrial activity of the human heart is normally visible in the electrocardiogram as a P-wave. In patients with intermittent atrial fibrillation, a different P-wave morphology can sometimes be seen, indicating atrial conduction defects. The purpose of this study was to develop a method to discriminate between such P-waves and normal ones. 20 recordings of each type were used in a classification

En empirisk vetenskap om duet : Om Alfred Schutz bidrag till sociologin

Popular AbstractDenna avhandling behandlar Alfred Schutz (1899-1959) sociologiska ansats, tidigt av honom själv benämnd som en empirisk vetenskap om duet, med fokus på den teori han utarbetade i syfte att förstärka den förstående sociologin. Baserat på metodologiska resonemang om möjligheten att nå en vetenskaplig kunskap om den meningskontext den andre, duet, handlar utifrån fördjupade Schutz denThis dissertation examines Alfred Schutz's (1899-1959) approach to sociology, which early in his work he called an empirical science of the thou, with an emphasis on the sociological theory he worked out to strengthen interpretive sociology. Based on a methodological understanding about the possibility of being able to achieve scientific knowledge of the other's, the thou's, context within which m

Retrofocusing of Acoustic Wave Fields by Iterated Time Reversal

In the present paper an iterative time-reversal algorithm that retrofocuses an acoustic wave field to its controllable part is established. For a fixed temporal support, i.e., transducer excitation time, the algorithm generates an optimal retrofocusing in the least-squares sense. Thus the iterative time-reversal algorithm reduces the temporal support of the excitation from the requirement of negli

Incidence of cardiovascular disease, cancer and death in postmenopausal women affirming use of hormone replacement therapy.

AIM: The goal of this study was to evaluate the incidence of myocardial infarction, cancer and death in relation to use of hormone replacement therapy (HRT). METHODS: Nine years' follow up of an urban cohort of peri-/postmenopausal women was undertaken. Local and national registers were used for retrieval of events. RESULTS: The incidence of myocardial infarction per 1.000 person-years in users an

Characterisation of anaerobic mixed cultures by partition in an aqueous two-phase system

A method to characterise a dynamic microbial consortium is described. By exploiting differences in surface properties between different cells and between cells of different physiological status, it was possible to develop a partition pattern for a mixed culture under different conditions. The separation method used was partition in aqueous two-phase systems and when using a counter current extract

Simultaneous OH- and Formaldehyde-LIF Measurements in an HCCI Engine

Simultaneous OH- and formaldehyde LIF measurements have been performed in an HCCI engine using two laser sources working on 283 and 355 nm, respectively. Two ICCD camera systems, equipped with long-pass filters, were used to collect the LIF signals. The simultaneous images of OH and formaldehyde were compared with heat-release calculated from the pressure-trace matching the cycle for the LIF measu

Retention patterns of asbestos fibres in lung tissue among asbestos cement workers

Retention patterns in lung tissue (determined by transmission electron microscopy and energy dispersive spectrometry) of chrysotile, tremolite, and crocidolite fibres were analysed in 69 dead asbestos cement workers and 96 referents. There was an accumulation of tremolite with time of employment. Among workers who died within three years of the end of exposure, the 13 with high tremolite concentra

Supersymmetric extensions of Calogero-Moser-Sutherland-like models: construction and some solutions

We introduce a new class of models for interacting particles. Our construction is based on Jacobians for the radial coordinates on certain superspaces. The resulting models contain two parameters determining the strengths of the interactions. This extends and generalizes the models of the Calogero-Moser-Sutherland type for interacting particles in ordinary spaces. The latter ones are included in o

Van Gujjars: The Persistent Forest Pastoralists

During the last decade the condition of life has changed in many ways for the pastoral Van Gujjar who have their winter camps in the interior of the forests of the Shiwalik foot hills of Uttar Pradesh and Uttaranchal in northern India. While the Gujjar in most of northern India are a very large and ethnically as well as religiously diversified population, the pastoral Gujjar in this particular are

Fed-batch cultivation of Saccharomyces cerevisiae on lignocellulosic hydrolyzate

Saccharomyces cerevisiae grows very poorly in dilute acid lignocellulosic hydrolyzate during the anaerobic fermentation for fuel ethanol production. However, yeast cells grown aerobically on the hydrolyzate have increased tolerance for the hydrolyzate. Cultivation of yeast on part of the hydrolyzate has therefore the potential of enabling increased ethanol productivity in the fermentation of the h

Penicillin V, loracarbef and clindamycin in tonsillar surface fluid during acute group A streptococcal pharyngotonsillitis.

Patients with acute group A-strepotococcal pharyngotonsillitis were randomly assigned to treatment for 10 d with either phenoxymethylpenicillin (PcV), loracarbef or clindamycin. The concentrations of the drugs, respectively, were determined in tonsillar surface fluid (TSF), serum and the saliva in each patient on altogether 5 occasions; before, during and 4 d after end of therapy. On the same occa

Trust, Threat, and Stable Peace. : Swedish Great Power Perceptions 1905-1939

This study is ultimately concerned with the attainment of stable peace in international affairs. The notion of stable peace-understood as military conflict resolution being unthinkable, no matter the severity of a conflict-rivals traditional accounts of the logic of international relations. Confidence-certainty as to the intentions of another actor-are at the heart of stable peace relationships. I
