Nuclear quadrupole resonance (NQR) is a radiofrequency technique that can be used to detect the presence of quadrupolar nuclei, such as the N-14 nucleus prevalent in many explosives and narcotics. In a typical application, one observes trains of decaying NQR echoes, in which the decay is governed by the spin echo decay time(s) of the resonant line(s). In most detection algorithms, these echoes are
OBJECTIVES: To investigate prospectively long term patient relevant outcomes after unilateral total hip replacement (THR) for osteoarthritis (OA). To identify non-responders to this intervention and patient related predictors of unsatisfactory outcome.METHODS: A case-control study comparing health related quality of life of 219 patients (mean age 71) after THR with that of a matched reference grou
We have studied PCB concentration and domain (one to three congeners) distribution in water and fish along a gradient of a contaminated river system. The river was contaminated by a small lake that contains about 400 kg of PCB in the sediment. The PCB concentration in water in the outlet from the lake was 8.6 ng/L, which was 12 times higher than upstream. PCB concentration in fish from the lake wa
The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional le
This report describes experimental studies of the mechanical performance of self-compacting concrete, SCC, under compresseive loading at fire temperatures. The SCC contains different amounts of polypropylene fibre, different types of cement and air content, preconditioned either in the air or in water. The result of the studies was compared with the corresponding properties of normal concrete, wit
Popular Abstract in Swedish Den centrala punkten i avhandlingen är det faktum att redan under järnåldern har det varit möjligt att urskilja olika lokala särdrag i ett arkeologiskt material. För såväl gravar som hus har man varit noga med att följa det egna närområdets traditioner. Erfarenheterna från Halland visar att trots likartad ekonomi har husen men också det synliga gravskicket varierat betyThe aim of the dissertation is to elucidate Iron Age settlement in southern Halland from two angles: (1) the evidence of antiquities (graves), ground finds of metal and rock, and place-names; (2) the information conveyed by investigations in settlement archaeology. The combined study of graves, ground finds, and place-names shows that the image of southern Halland in the Iron Age differs depending
I föreliggande rapport redovisas resultaten från provningar av ett antal putssystem applicerade på mineralull. Provningarna har gjorts på provväggar cirka 5.5 x 2.5 m2. Både i praktiken förekommande system med stålnätsarmering och experimentella system har provats. Efter putsning och viss härdning har putsen utsatts för upprepade uppfuktningar /uttorkningar. Eventuell sprickbildning har studerats

Water-soluble non-structural carbohydrates (NSC) in the needles of Norway spruce Picea abies [L.] Karst have been studied by using a combination of several separation techniques, having various detectors, with mass spectrometry. The intent was to find a suitable methodology that enables the characterization and determination of NSC, covering a wide range of molar masses, and being suitable to asse
In this explorative paper, coalitions in national assemblies are analysed as n-person games with the Penrose-Banzhaf solution concept. It is shown that forming minority coalitions may result from a rational strategy to maximize voting power. Thus, there is no need to attempt a permanent minimum winning coalition. Moreover, maximizing voting power for a group of players like a disciplined political
Källarlös grundläggning av byggnader kan utföras med s.k. kryprum. Svensk byggnorm (SBN 67) benämner detta "fribärande golvbjälklag över slutet ventilerat utrymme under jord". l rapporten behandlas både ventilerade och oventilerade utrymmen med hänsyn till grundläggningsdjup, fuktförhållanden och erforderlig värmeisolering av bjälklag. Rapporten bygger på datorberäkningar av frostnedträngningen oc
A systematic assessment of radiotherapy for cancer was conducted by The Swedish Council on Technology Assessment in Health Care (SBU) in 2001. The assessment included a critical review of the literature on radiotherapy for cancer published in 1994-2001 and a prospective survey of radiotherapy practice in Sweden during 12 weeks in the autumn of 2001. The results of the survey were compared with the
In societies with an increasing proportion of elderly active people it is valuable to gain knowledge about what elderly people actually do and want to do in relation to activity arenas in the public environment. The main aim of this study was to investigate elderly people’s preferences and frequencies of visits to public facilities in a Swedish town center. A further aim was to gather information
Antimicrobial peptides produced by epithelial cells and neutrophils represent essential elements of innate immunity, and include the defensin and cathelicidin family of antimicrobial polypeptides. The human cathelicidin cationic antimicrobial protein-18 is an antimicrobial peptide precursor predominantly expressed in neutrophils, and its active peptide LL-37 is released from the precursor through
In 48 patients with a history of a pneumococcal bacteremia, serum taken during the acute phase of the infection was analyzed for IgG and IgG subclasses. Once the patients were free of infection, a serum sample was analyzed for IgG, IgG subclasses, IgA and IgM. In an additional 20 patients, it was only possible to analyze serum from the infection-free phase. Seventeen of 48 (35%) patients had reduc
This article reports on a multiblock implementation of a general three-dimensional single-block computational fluid dynamics code, which is developed in a nonorthogonal, structured, collocated finite-volume grid system, and incorporates a range of turbulence models. The multiblock implementation is essentially block-unstructured, each block having its own local coordinate system unrelated to those
