2. 6. Expression and structure-function characterisation of herpesviral proteins

   Author : Sue-Li Dahlroth; Pär Nordlund; Darren Hart; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein production; Herpesvirus; SOX; E. coli; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : In order to determine and study a protein structure, large amounts of it is needed. The easiest way to obtain a protein is to recombinantly overexpress it in the well-studied bacterium Escherichia coli. However, this expression host has one major disadvantage, overexpressed proteins might not be folded or be insoluble. READ MORE

4. 7. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases

   Author : Jakob Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOx; absorption; ClO2; sulfite oxidation; gas-phase oxidation; NOx; Emissions control; scale-up;

   Abstract : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. READ MORE

5. 8. Sulphur Regulations for Shipping – Why a Regional Approach?: Scientific and Economic Arguments in IMO Documents 1988-1997

   Author : Erik Svensson; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; costs; framing; shipping; SECA; distribution; environmental; policy environment; international; MARPOL; conceptual lens; IMO; Annex VI; regional approach; economic interests; directional problem; benefits; policy-making; SOx; science;

   Abstract : Some environmental issues for shipping are regulated globally with uniform standards and others with stricter regulations in specific areas. This thesis aims to provide an understanding of why a regional approach was chosen with SOx Emission Control Areas (SECAs) as the main form of control of sulphur oxide emissions from international shipping, with explanations based on documents from negotiations within the International Maritime Organization (IMO) during 1988-1997.

6. 9. Exhaust aftertreatment under lean conditions, regenerable SOx traps and NOx reduction catalysts

   Author : Lisa Kylhammar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogenous catalysis; Selective catalytic reduction; HC-SCR; Sulfur storage; SOx trap; Spectroscopy; Lean exhausts; NOx; Ag Al2O3; DRIFT; XPS;

   Abstract : The aim of this thesis was to investigate i) potential materials for regenerable SOx traps and ii) the influence of silver distribution within Ag/Al2O3 catalysts on the selective reduction of NOx by hydrocarbons (HC-SCR). Both areas are highly relevant for present and future vehicle aftertreatment technologies for lean exhausts. READ MORE

7. 10. Regulating Vessel-Source Air Pollution - Standard-Setting in the Regulation of SOx Emissions

   Author : Philip Almestrand Linné; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ships; air pollution; SOx emissions; regulation; regulatory design; command and control; standard-setting; international environmental law; regulatory studies;

   Abstract : Emissions of sulphur oxides (SOx) cause considerable global environmental and human health impacts including acidification, climate change, and increased premature deaths in human populations due to serious heart and lung diseases. Although recently revised regulations in MARPOL 73/78 Annex VI are expected to decrease SOx emissions from ships, it is clear that these regulations will need further development. READ MORE
