1. 11. FRP shear strengthening of RC beams and walls

   Författare :Gabriel Sas; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : The shear failure of Fibre Reinforced Polymers (FRP) strengthened reinforced concrete (RC) beams has not been studied to the same extent as the bending failure mechanism in the past decade. The complex nature of the shear failure mechanism just for reinforced concrete beams is still under debate among scientists and not solved yet. LÄS MER

3. 12. Men in Politics : Revisiting Patterns of Gendered Parliamentary Representation in Thailand and Beyond

   Författare :Elin Bjarnegård; Maria Heimer; Axel Hadenius; Erik Melander; Martha Blomqvist; Georgina Waylen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; clientelism; political parties; representation; candidate selection; Thailand; gender; masculinities; democratization; social capital; homosociality; homosocial capital; Political science; Statsvetenskap; Statskunskap; Political Science;

   Sammanfattning : Male parliamentary dominance, rather than the corresponding female parliamentary underrepresentation, is the object of study in this thesis. This shift in focus implies a gendered analysis centered on men and men’s practices. LÄS MER

4. 13. Studies on Building Air Leakage -a transient pressurisation method, measurements and modelling

   Författare :Björn Mattsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air change rate; Airtightness; CFD-simulations; moisture transport; air leakage; mould growth; cold attics; transient pressurisation;

   Sammanfattning : Airtightness of the building envelope is a key factor for good performance of a building. The main part of this thesis deals with the exploration of a transient pressurisation method for air leakage measurements.In the transient method, an enclosure is pressurised to a desired pressure. The air flow into the enclosure is then stopped. LÄS MER

5. 14. Unlocking the hidden diversity of organic-walled microfossils from the early Cambrian of North Greenland

   Författare :Elise Wallet; Sebastian Willman; Ben Slater; Graham Budd; Charles H. Wellman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cambrian; acritarchs; organic-walled microfossils; small carbonaceous fossils; Greenland; diversity; disparity; taxonomy; taphonomy; Crustacea; plankton; Historical Geology and Paleontology; Historisk geologi och paleontologi;

   Sammanfattning : The early Cambrian Buen Formation of North Greenland is celebrated for hosting one of the oldest Cambrian Burgess Shale-type deposits known to date – the Sirius Passet Lagerstätte. Further south in a shallower shelf facies belt, the Buen Formation yielded organic-walled microfossils (OWMs) that were originally described with a focus on acritarchs. LÄS MER

7. 15. Functional polymer brush coatings for nanoscale devices

   Författare :John Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; poly ethylene glycol ; nanopores; electrochemistry; silatranes; func- tional materials; polymer brush; Nanobiotechnology; interpolymer complex; pH re- sponsive; macromolecular gating.;

   Sammanfattning : Nanobiotechnology is an interdisciplinary field that has garnered considerable attention for offering exciting new opportunities of studying and manipulating biomolecules at the nanoscale. This prospect bears large potential benefits in the field of medicine and the whole life science sector in general. LÄS MER
