2. 11. Precise Gravimetric Geoid Model for Iran Based on GRACE and SRTM Data and the Least-Squares Modification of Stokes’ Formula : with Some Geodynamic Interpretations

   Author : Ramin Kiamehr; Lars Sjöberg; Martin Vermeer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gravity database; least-squares modification of Stokes; geoid determination; SRTM; GRACE; GPS levelling; density variation model; height datum; geodynamics; Iran; Earth sciences; Geovetenskap;

   Abstract : Iran is one of the most complicated areas in the world from the view of rough topography, tectonic activity, large lateral density and geoidal height variations. The computation of a regional gravimetric geoid model with high accuracy in mountainous regions, especially with sparse data, is a difficult task that needs a special attention to obtain reliable results which can meet the needs of the today geodetic community.

4. 12. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

   Author : Klas Folkesson; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; windthrow detection;

   Abstract : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

5. 13. Outcome and prevention strategies in peritoneal adhesion formation

   Author : Fanny Fredriksson; Helene Lilja; Bobby Tingstedt; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peritoneal adhesion prevention; inflammatory cytokines; experimental adhesion model; adhesive small bowel obstruction; adhesion-related morbidity; Barnkirurgi; Pediatric Surgery;

   Abstract : Peritoneal adhesions occur in up to 93% of adults after peritoneal trauma during surgery. Most adhesions are asymptomatic but can cause female infertility, small bowel obstruction (SBO) and chronic abdominal pain. Adhesion prophylaxis is needed to reduce the significant morbidity and increased health care costs resulting from peritoneal adhesions. READ MORE

6. 14. The bank vole (Myodes glareolus) – a novel animal model for the study of diabetes mellitus

   Author : Martin Blixt; Stellan Sandler; Johnny Ludvigsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bank vole; pancreatic islets; diabetes mellitus; hydropic degeneration; proinflammatory cytokine; Diabetology; Diabetologi; Endocrinology; Endokrinologi; Medical Cell Biology; Medicinsk cellbiologi;

   Abstract : The bank vole (Microtus arvalis) develops glucose intolerance both when kept in captivity and in the wild state. Glucose intolerant bank voles kept in captivity exhibited polydipsia, polyuria, hyperglycemia, hyperinsulinemia, islet autoantibodies and a markedly changed islet structure resembling so–called hydropic degeneration.

7. 15. Involvement of Membrane Transport Proteins in Intestinal Absorption and Hepatic Disposition of Drugs Using Fexofenadine as a Model Drug

   Author : Niclas Petri; Hans Lennernäs; Geoffrey Tucker; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Fexofenadine; OATP; P-glycoprotein; Organic Anion Transporters; ATP-Binding Cassette Transporters; membrane transport proteins; Bioavailability; Biopharmaceutics; Biofarmaci; Biopharmacy; Biofarmaci;

   Abstract : The aims of this thesis were to study the in vivo relevance of membrane transporters for intestinal absorption and the hepatic disposition of drugs in humans and preclinical models. Fexofenadine is a substrate for ABCB1 (P-glycoprotein) and members of the organic anion transporting polypeptide (OATP/SLCO) family. READ MORE
