1. Structure determination, thermal stability and catalytic mechanism of hyperthermostable isocitrate dehydrogenases
Sammanfattning : In this thesis, studies on the enzyme isocitrate dehydrogenase (IDH) from the hyperthermophiles Aeropyrum pernix (ApIDH), Thermotoga maritima (TmIDH), Archaeoglobus fulgidus (AfIDH) and Pyrococcus furiosus (PfIDH) are presented. The aim of the described work was to contribute to the understanding of protein thermostability and to study the catalytic mechanism. LÄS MER
2. Chemical emissions from concrete
Sammanfattning : The major part of this work deals with a new method for quantification of VOCs in concrete. There is a need for this type of quantification due to the development in cement and concrete production using plasticizing agents and fillers for improved rheological properties, and alternative fuels and waste materials to reduce the environmental impact of cement production.

3. Bleeding and hemostasis during normo- and hypothermia : studies on porcine and rat models
Sammanfattning : Background: Numerous animal studies have shown protective effects of hypothermia (HT) on hemorrhagic shock. These findings do not correlate with clinical findings, were studies on trauma registers have shown that HT is an independent factor of death when associated with trauma. LÄS MER
4. PWO Crystal Measurements and Simulation Studies of Anti-Hyperon Polarisation for PANDA
Sammanfattning : The Gesellschaft für Schwerionenforschung (GSI) facility in Darmstadt, Germany, will be upgraded to accommodate a new generation of physics experiments. The future accelerator facility will be called FAIR and one of the experimentsat the site will be PANDA, which aims at performing hadron physics investigations by colliding anti-protons with protons.

5. Syntheses of some tri- and tetracyclic heterocycles containing an indole moiety
Sammanfattning : This thesis deals with the development of new synthetic methods leading to fused tri- and tetracyclic heterocycles, many of which have interesting biological activity such as antiviral and DNA intercalating properties. The reactions between isatins and 2-aminobenzylamine in acetic acid can give, depending on the conditions, either complex spirooxindoles or indolo[3,2-c]quinolin-6-ones. LÄS MER
