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
I denna rapport redovisas nio daghem och åtta skolor i vilka brukarna upplever ett tillfredsställande inneklimat. Både ny- och ombyggda objekt behandlas. Varje objekt redovisas med syfte, organisation av byggprocessen, bakgrundsfakta om byggnaden, produktions- och driftskostnader, tekniska fakta om konstruktion, material, värme och ventilation, energianvändning, städvanor samt utvärdering av enkät
New basis sets of the atomic natural orbital (ANO) type have been developed for the actinide atoms Ac-Cm. The ANOs have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive ions, and the atom in a electric field. Scalar relativistic effects are included through the use of a Douglas-Kroll-Hess Hamiltonian. Multiconfigurational wave function
The chorophyll-protein complex CP43 is a proximal-antenna subunit important for excitation energy transfers from peripheral light-harvesting antenna to the Photosystem II (PSII) reaction centre. We report persistent spectral hole burning at 1.7 K in the Qy(0,0) origin and Qy(1,0) vibrational satellite bands of chorophyll a (chl a) in CP43 isolated from higher plants. The isolated CP43 is known to
To understand by which mechanism neural cell adhesion molecule (N-CAM) limits tumour cell disaggregation and dissemination, we searched for potential downstream genes of N-CAM during tumour cell progression by gene expression profiling. Here, we show that N-CAM- deficient - cell tumorigenesis is associated with changes in the expression of genes involved in cell-matrix adhesion and cytoskeletal dy
The needs of parents of hospitalized children have received some attention in the health literature, but few studies have compared parents' perceptions of needs with staff's ideas about parents' needs. The aim of this study was to examine differences between the perceptions of the needs of parents of hospitalized children held by staff - nurses, doctors and allied health staff, and parents in a 15
