The early Middle Ages saw the formation of the three Nordic kingdoms of Sweden, Norway and Denmark, and at that time the area studied here constituted a border region between them. During the same period the Church was very active in the area: a bishopric was established and a large number of churches were built. This makes the area a particularly interesting one to study from the point of view of

Introduction. The aim of the study reported is to examine user discourses identified in the Swedish public library field. The following questions are posed: What user discourses can be found and what characterises them? How are users categorised and what does this categorisation imply? The departure point in this paper is that the ways users are categorised may influence their information behaviou

Popular Abstract in Swedish Moraxella catarrhalis är en bakterie som tillhör vår normala bakterieflora. Den är dock också en luftvägspatogen som kan orsaka öroninflammation hos barn, nedre luftvägsinfektioner hos vuxna och äldre, och bihåleinflammation hos både barn och vuxna. Intresset kring M. catarrhalis som patogen har ökat de senaste 20 åren, både på grund av ökat antal insjuknande personer oMoraxella catarrhalis is a respiratory tract pathogen that causes significant health problems, including acute otitis media in children, lower respiratory tract infections in adults and the elderly and sinusitis in both children and adults. The interest in M. catarrhalis bacteria has increased over the past 20 years, both because of the emergence of the bacteria as a human pathogen and because of

Popular Abstract in Swedish I utvecklingen av gasturbiner och förbränningsmotorer (som används i bilar, flygplan & båtar) finns idag ett modernt miljötänkande som strävar efter att reducera utsläpp och öka effektiviteten (verkningsgraden). Med användning av rätt kylmetoder kan man påverka dessa parametrar. Den bästa möjliga kyltekniken skapar utrymme för att höja temperaturen vid förbränningenThe mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. Traditional cooling schemes such as film cooling are associated with high coolant flow rates and unacceptable emission lev

Relay feedback has a large variety of applications in control engineering. Several interesting phenomena occur in simple relay systems. In the paper, scalar linear systems with relay feedback are analyzed. It is shown that a limit cycle where part of the limit cycle consists of fast relay switchings can occur. This chattering is analyzed in detail and conditions for approximating it by a sliding m

GaAs:Mn nanowires were obtained on GaAs(001) and GaAs(111)B substrates by molecular beam epitaxial growth of (Ga,Mn)As at conditions leading to MnAs phase separation. Their density is proportional to the density of catalyzing MnAs nanoislands, which can be controlled by the Mn flux and/or the substrate temperature. After deposition corresponding to a 200 nm thick (Ga,Mn)As layer the nanowires are

In this work, we report on an overview of recent results from Fourier transform photocurrent (FTPC) measurements in the infrared spectral region on ensembles of self-assembled InAs quantum dots embedded in a matrix of InP. In interband PC, clear signals related to the dots are observed. Comparing the PC- and PL spectra, we observe that the fundamental transition is absent in the PC spectra, which

Objectives: To investigate efficacy, safety, and impact on quality of sleep of desmopressin in the treatment of nocturia. Methods: Adults aged >= 18 yr with nocturia (>= 2 voids/night) received desmopressin tablets (0.1, 0.2, or 0.4 mg) during a 3-wk dose-titration period. Patients should show sufficient response during the dose-titration period (>= 20% reduction in nocturnal diuresis) and a retur

In order to produce drinking water, coagulants - such as aluminium salts - are widely used for precipitation and separation of impurities from raw water. The residual from the process is sludge, which presents a disposal problem. The REAL process is a method for recycling the aluminium from the sludge. In a first step, the aluminium hydroxide is dissolved in sulphuric acid. In a second step, an ul

Popular Abstract in Swedish I denna avhandling studeras skolsituationen för elever med båda föräldrarna födda utomlands. Samband mellan elevernas bakgrund, övriga faktorer som i tidigare forskning visat sig betydelsefulla och skolresultat identifieras och analyseras. Studien utgår från de data som insamlades inom ramen för "Det nationella programmet för utvärdering", som genomfördes 1992. UtvärderThe overall purpose of this study was to provide knowledge about the school situation of pupils in Sweden whose parents were both born abroad. The connections between the pupils’ background, other factors shown to be significant in earlier studies, and school results have been identified and analysed. The study was based on the data compiled as part of the National Programme of Evaluation, which w

The molecular basis of L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia (LID), one of the major hindrances in the current therapy for Parkinson's disease, is still unclear. We show that attenuation of cAMP signaling in the medium spiny neurons of the striatum, achieved by genetic inactivation of the dopamine and cAMP-regulated phosphoprotein of 32 kDa (DARPP-32), reduces LID. We also show

PCB concentrations were studied in different soils to determine the spatial variation over a region of approximately 11000 km(2). PCB congener pattern was used to illustrate the spatial differences, as shown by principal component analysis (PCA). The relationship to different soil parameters was studied. PCB concentrations in soil showed a large variation between sampling-areas with median concent
