The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. In order to represent the particulate and droplet phase, the Volume of Fluid (VOF) and the Volume of Solid (VOS) methods ar
Organ transplantation provides a treatment of end-stage disease primarily in the kidney, liver and heart. The immunosuppressive treatment regimens of today efficiently prevent early acute rejection; however the long-term survival has not improved to the same extent. Within months/years the majority of transplanted organs develop chronic allograft dysfunction (CAD), associated with fibrosis and int
The study deals with strain on the family system, as well as the level of coping and types of coping behavior of the parents, in families with a child diagnosed as having an autistic spectrum disorder (ASD) as compared to families in a control group. Thirty-seven families and 66 parents were involved in each case, and four psychological tests were used. It was found that lower levels of coping wer
Positron annihilation lifetime spectroscopy (PALS) was performed on a series of polydimethylsiloxane (PDMS)/fumed silicon dioxide (SiO2) composites at temperatures between -185 and 100degreesC to study the effect of filler content and filler particle size on the free volume properties and the positron annihilation characteristics. The glass transition behavior of the PDMS/SiO2 composites was deter
This paper describes a project course that focuses on the design of analog and mixed signal circuits through a systematic top down design flow. In the project, the student will be involved in the planning, modeling, circuit level design, physical level implementation and measurement verification of for example a successive approximation (SA) ADC or a class-D audio amplifier. Throughout the project
Derivatised polysaccharides are polymers from renewable sources of great importance in a whole range of different industries. However, only until recently have their characterisation been hampered by the lack of suitable instrumental methods or rather combination of suitable instrumentation. This review gives details on the state-of-the-art on polysaccharide analysis, especially focussing on starc
Smoking is a serious risk factor for cardiovascular disease, retinopathy, and nephropathy in patients with diabetes. Furthermore, epidemiological studies have shown that heavy smokers run an increased prospective risk of developing type 2 diabetes, probably due both to the fact that smoking is a marker for an unhealthy lifestyle and that smoking via nicotine may deteriorate glucose metabolism by n
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
The k-point correlation functions of the Gaussian random matrix ensembles are certain determinants of functions which depend on only two arguments. They are referred to as kernels, since they are the building blocks of all correlations. We show that the kernels are obtained, for arbitrary level number, directly from supermatrix models for one-point functions. More precisely, the generating functio
The long-term outcome from silicone tube nerve repair was compared with the outcome from routine microsurgical repair in a clinical randomized prospective study, comprising 30 patients with median or ulnar nerve injuries in the distal forearm. Postoperatively, the patients underwent neurophysiological and clinical assessments of sensory and motor function regularly over a 5-year period. After 5 ye
Type 2 diabetic patients often die because of end-stage renal failure, but no definitive reliable factor predicting long-term renal outcome has been identified. We tested whether a renal arterial resistance index (R/I) >= 80, using Doppler ultrasound technique, was predictive of worsening renal function. The primary end points of the study were 1) the course of glomerular filtration rate (GFR) and
In this article career as metaphor and various career models are the object of a critical review. The question at issue is whether career as metaphor helps us understand the social dynamics that characterize substance abuse? Different career models such as the stepping-stone and gateway hypothesis and H S Beckers career model is scrutinized. It is pointed out that these career models are one-sided
