2. 1. Topics in multifractal measures, nonparametrics and biostatistics

   Author : Attila Frigyesi; Anestesiologi och intensivvård; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; confidence interval; mixed effects; Statistics; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik; operational model of pharmacological agonism; concentration-response curves; dose-response curves; ventilation perfusion scintigraphy; V Q-scan; pulmonary embolism; automated method; box counting; correlation dimension; Hentschel-Procaccia dimension; Rényi dimension; generalized dimensions; fractal dimension estimation; dimension spectrum; multifractal measures; kernel density estimates; absolute continuity; singular distribution functions;

   Abstract : This thesis consists of four papers. The first two papers, which comprise the main part of the thesis, deal with an unexpected connection between kernel density estimators and dimension spectra for multifractal measures. READ MORE

4. 2. Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria

   Author : Susann Milenkovski; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fungicide; concentration-response curves; nosZ; nirS; nirK; bacterial activity; denitrification; bacterial community composition; herbicide; insecticide;

   Abstract : This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. READ MORE

5. 3. Conctraction-mediating receptors in human peripheral vessels with special reference to veins and lymphatics

   Author : Trygve Sjöberg; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; arteries; veins; lymphatis; contraction; in vitro; in vivo; adrenergic receptors; noradrenaline; cirazoline; phenylephrine; clonidine; calcium antagonists; nifedipine; diltiazem; prostaglandins; thromboxane A2; U-46619; BM-13.505; indomethacin;

   Abstract : By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. READ MORE

6. 4. On methods for probing structure and function of membrane proteins

   Author : Erik Jansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; proteomics; patch-clamp; mass spectrometry.; proteoliposomes; microfluidic superfusion; cholesterol; TRPV1; limited proteolysis; Membrane proteins; fluorescence;

   Abstract : The determination of structure–function relationships in membrane proteins plays a key role for the understanding of molecular mechanisms in biological systems, and may provide information on how these systems can be modulated by pharmaceuticals. The aim of the work described herein was to develop methods for studying structure and function of membrane proteins, ideally in combination. READ MORE

7. 5. Chemical induction of spindle disturbances and abnormal chromosome numbers in cultured mammalian cells

   Author : Agneta Önfelt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Early investigations have shown that many chemically different compounds can cause spindle disturbances in eukaryotic cells and that there is an unspecific (physical) mechanism based on the partitioning of the compound into cellular hydrophobic compartments. This suggests that the approach should be quantitative when testing compounds for spindle disturbing activity in vitro; effect/no effect is not the most pertinent question. READ MORE
