2. 1. Geochronology of Tectonothermal Events in the Parautochthonous Eastern Segment of the Sveconorwegian (Grenvillian) Orogen, Southwestern Sweden

   Author : Ulf Söderlund; Berggrundsgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sveconorwegian; SW Sweden; Eastern Segment; geochronology; U-Pb; zircon; titanite; polymetamorphic; high-grade; Geology; exhumation; physical geography; Geologi; fysisk geografi;

   Abstract : Timing of deformation and metamorphism yield important information for understanding the development of orogenic processes and correlation of mobile belts and continents. This thesis adds new geochronological data constraining the age of protoliths and events of reworking in the frontal region of the c. 1.2-0. READ MORE

4. 2. Envelopes of holomorphy for bounded holomorphic functions

   Author : Ulf Backlund; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; holomorphicfunction; boundedholomorphic function; domain of holo¬ morphy; envelope of holomorphy; Gleason’s problem; convex set; plurisubharmonic function; pluripolar set; poly normally convex set;

   Abstract : Some problems concerning holomorphic continuation of the class of bounded holo­morphic functions from bounded domains in Cn that are domains of holomorphy are solved. A bounded domain of holomorphy Ω in C2 with nonschlicht H°°-envelope of holomorphy is constructed and it is shown that there is a point in D for which Glea­son’s Problem for H°°(Ω) cannot be solved.

5. 3. Latent messenger RNA in dormant Artemia embryos

   Author : Mats Ola Nilsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis deals with the demonstration and partial characterization of latent messenger RNA in encysted Artemia embryos.RNA was extracted from subcellular fractions of dormant Artemia cysts and tested for template activity in a messenger RNA deficient amino acid incorporating bacterial system.

6. 4. Molecular aspects of cellular radiosensitivity in small cell lung carcinoma

   Author : Florin Sirzén; Karolinska Institutet; Karolinska Institutet; []
   Keywords : lung carcinoma; radiosensitivity; DNA double-strand breaks; DNA-dependent protein kinase; cell cycle checkpoints; apoptosis;

   Abstract : To clarify some important molecular aspects of radiosensitivity (RS) in small cell (SCLC) compared with non small cell (NSCLC) lung carcinoma, five studies focusing on DNA damage repair, cell cycle checkpoints and apoptosis were performed. As repair of DNA double-strand breaks (DNA dsb), a critical DNA lesion, may be an important determinant of cellular RS, induction and rejoining of DNA dsb were studied using pulsed field gel electrophoresis in a radiosensitive SCLC line, U-1285 and a radioresistant NSCLC line, U-1810 (paper I).

7. 5. Molecular Interactions Studied by Electrophoretic and Diffusion NMR

   Author : Fredrik Hallberg; Peter Stilbs; István Furó; Gareth Morris; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; NMR; electrophoretic NMR; Ion pairing; complexation; association; diffusion; pulsed field gradient; Nafion; Spectroscopy; Spektroskopi;

   Abstract : Even though electrophoretic NMR (eNMR) experiments may provide unique chemical information and have been performed for three decades, the technique is still rarely applied, mainly because several experimental sources of artifacts have to be controlled to achieve accurate results. In this thesis, new experimental setups and protocols for accurate and precise eNMR experiments are presented. READ MORE
