Many studies have reported higher total plasma homocysteine (tHcy) in elderly patients with mental illness than in control subjects. There are many different determinants of plasma tHcy concentration, including age, cobalamin/folate status, renal function and the presence of vascular disease. The presence of vascular disease may contribute to cognitive impairment. We have investigated elderly pati
OBJECTIVE: Heart rupture is a devastating complication to negative pressure wound therapy in cardiac surgery. Also, reduced cardiac output during negative pressure wound therapy has been reported. The present study aimed to examine the effects of negative pressure wound therapy on the position of the heart in relation to the thoracic wall using magnetic resonance imaging in a porcine sternotomy wo
Remote laser-induced fluorescence monitoring can complement passive reflectance measurements on vegetation. Vegetation classification and status assessment is normally performed by air- or spaceborne multi-spectral scanners. An increased research activity in the field of vegetation monitoring is motivated by the abundant stressed forests of Europe. We have used a mobile lidar system for remote stu
Abstract in Undetermined Archaeological research on pre-Christian religion has increased greatly during the last two decades. Studies of ritual and religion appear frequently in scholarly, popular and antiquarian publications of the 1990s. Selected publications in Scandinaviau archaeology are presented in order to characterise and discuss different approaches. Central theoretical and methodologica
The T-matrix method is applied to the problem of scattering of Rayleigh-Lamb modes from a twodimensional cavity in an elastic plate. A formal solution is obtained which is valid also for non-planar surfaces. Explicit expressions and numerical results are given for a plate with plane surfaces.
BACKGROUND AND AIMS: Monochromatic pulsating light may have effects on wound healing. In an earlier study of grade II ulcers, there was a tendency toward better healing in the phototherapy group (p=0.06). The present study on patients with grade II ulcers was performed to verify these findings. Data from this study were pooled with data from the earlier study. METHODS: Ninety-four patients were of
Nummer 3 av Naturvetaren innehåller en debattartikel av Ingvar Fogstam: “Vi kan inte stoppa naturliga klimatvariationer”. Den innehåller flera insinuationer och underliga påståenden med anknytning till IPCC-rapporterna.
In the present contribution we review some recent work on scattering of electromagnetic waves from various geophysical targets, by means of P. C. Waterman's approach. As an introduction to the specific applications to be described, a general outline is given of the basic features of this approach, as applied to electromagnetic waves. The algebraic structure of the resulting equations for single an
Software release planning takes place on strategic and operational levels. Strategic release planning aims at assigning features to subsequent releases such that technical, resource, risk and budget constraints are met. Operational release planning focuses on the development of a single software release. Its purpose is to assign resources to feature development tasks such that total release durati
