1. Overcoming the Barriers of Fine-Needle Aspiration
Sammanfattning : Cysts, closed sac-like structures filled with fluid or air, can form anywhere in the body. In the majority of cases, cysts are benign (not cancerous). However, these structures can also be precursors of cancer, pointing to the location where cancer can originate. LÄS MER
2. The enterocyte in small intestinal adaption : an experimental and clinicopathological study with special reference to the ultrastructure of the brush border
Sammanfattning : The small intestine mucosa is known to be able to adapt itself to several kinds of both physiological and pathological conditions. The adaptive patterns of the structure of the enterocytes, particularly their apical surface (brush border), were studied in three models: (1) in rats, subjected to antrectomy or antral exclusion, combined with gastroduodenostomy and gastrojejunostomy; (2) in rats with alloxan diabetes; (3) in children with coeliac disease; a) in its active phase; b) after long-term treatment with gluten-free diets; c) after long-term challenge with dietary gluten following treatment; d) after short-term elimination of dietary gluten.

3. Topics in Modeling, Control, and Implementation in Automotive Systems
Sammanfattning : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. LÄS MER
4. Charged Polymers at Spherical Surfaces
Sammanfattning : Two separate topics in the area of colloidal chemistry have been investigated by the use of molecular modeling: the structural properties of polyion?macroion complexes and of diblock polyampholyte brushes. The main results were obtained by the use of Monte Carlo simulation in the framework of the primitive model, and in the case of polyampholyte brushes the simulation results were also complemented by lattice mean-field calculations.
