Object: The abdominal aorta (AA) has a predilection for aneurysm formation. An etiologic factor may be underlying aortic wall stress. The purpose of this study was to examine whether the intima-media thickness (IMT) of the AA, as a surrogate to arterial wall thickness, can be measured noninvasively with satisfactory results to calculate circumferential wall stress, and to evaluate regional and gen

A biosensor for monitoring acetonitrile was constructed. A mixed culture was taken from a degradation reactor and mounted on top of a Clark electrode. The amperometric biosensor was placed in a flow-through cell and integrated into a flow injection system. The metabolic response in terms of oxygen consumption was well correlated to the concentration of acetonitrile in standard solutions. However,

Previous time-use research suggests that it is highly relevant for an occupational therapist to estimate time use and occupational engagement in order to understand some of the determinants of wellbeing for people with schizophrenia. This article describes the development and the testing of the psychometric properties of an instrument, Profiles of Occupational Engagement in people with Schizophren

The effects on eating quality and meat quality of two different forms of post-slaughter treatment, performed in an abattoir, were studied in carriers and non-carriers of the RN− allele. Carcasses were subjected to rapid and slow chilling, and pelvic and Achilles suspension in a factorial experimental design. A temperature of 10 °C was achieved in the centre of M. longissimus dorsi (LD) within 3.5

Tio års erfarenheter av att anlägga gastrostomier på barn med hjälp av videoendoskop redovisas. I patientgruppen ingår 300 barn i åldern 3 månader till 18 år med neurologiska åkommor, metabola sjukdomar, medfödda hjärtmissbildningar och maligna sjukdomar. Operationen görs i intubationsnarkos med en videoassisterad anläggning av gastrostomi där en s k gastrostomiknapp placeras direkt i stomat och a

Because internal resources are finite, it has been assumed that attractive, floral organs represent a significant drain on the energy and nutrient budget of a plant. Despite the broad significance of such trade-offs, in relatively few studies have investigators manipulated floral investments, then evaluated allocation to subsequently produced flowers, fruits, and seeds. In the present study of Nig

Radiative lifetime measurements have been performed, with a time-resolved laser-induced fluorescence technique, for 12 levels of Os I and for 9 levels of Os II. For 9 levels of Os I and 4 levels of Os II, there were no previous experimental data available. From a comparison with new theoretical calculations, taking configuration interactions and core-polarization effects into account, it has been

Ambient solar radiation effects on Phragmites australis leaf and culm litter were investigated in a shallow and eutrophic south Swedish lake littoral. Leaf and culm litter was exposed to natural sunlight in the lake at a water depth of a few centimeters. For the leaf litter, an additional subset of the experiment was exposed to solar radiation in the air, to evaluate effects of the solar radiation

A fully integrated clock generator with behaviour similar to a PLL is proposed. A free-running ring oscillator is used as internal clock and the output clock is generated using two counters. The clock generator is described in synthesisable VHDL-code and can therefore easily be made from standard cells found in any commercial standard CMOS cell library.

The composition of cultivation media in relation to strain development for industrial application is reviewed. Heterologous protein production and pentose utilization by Saccharomyces cerevisiae are used to illustrate the influence of media composition at different stages of strain construction and strain development. The effects of complex, defined and industrial media are compared. Auxotrophic s

The Gaussian curvature of a two-dimensional Riemannian manifold is uniquely determined by the choice of the metric. The formulas for computing the curvature in terms of components of the metric, in isothermal coordinates, involve the Laplacian operator and therefore, the problem of finding a Riemannian metric for a given curvature form may be viewed as a potential theory problem. This problem has,

Popular Abstract in Swedish Att försöka lokalisera gener som ger upphov till sjukdomar är ingenting nytt. De första försöken gjordes redan i början av 1900-talet. Idén är ganska enkel. Man undersöker i vilka delar av genomet (arvsmassan) som generna tenderar till att skilja sig åt mellan sjuka och friska individer, men samtidigt delas av de sjuka individerna. Problemet är att det mänskliga genometThis thesis is interdisciplinary between Mathematical Statistics, Genetics, and Medicine. It mainly consists of topics in mathematical modelling of the correlation of inheritance of genes and disease in a family, a method called linkage analysis. It is organized as follows. First, a short introduction with the relevant background is given and then four papers are included. The first paper discuss
