2. 1. Becoming Jinja : The Production of Space and Making of Place in an African Industrial Town

   Author : Andrew Byerley; Gunilla Andrae; Jo Beall; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; space; place; diagrams of power; colonial planning; modernisation; model-modern; de-tribalisation; discipline; bio-politics; industrialisation; urban housing; urban agriculture; alcohol; Uganda.; Human geography; Kulturgeografi;

   Abstract : The years immediately preceding and following W.W.II marked a turning point in British colonial policy in Africa. In this doctoral thesis, which focuses on colonial and post-colonial Uganda, this turning point is approached in terms of a shift in would-be hegemonic socio-spatial diagrams of power. READ MORE

4. 2. Characterization and Directed Evolution of an Alcohol Dehydrogenase : A Study Towards Understanding of Three Central Aspects of Substrate Selectivity

   Author : Emil Hamnevik; Mikael Widersten; Gerrit Poelarends; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alcohol dehydrogenase; ADH-A; Biocatalysis; Directed evolution; Enantioselectivity; Enzyme kinetics; Enzyme mechanisms; Protein Engineering; Regioselectivity; Substrate selectivity; Biokemi; Biochemistry;

   Abstract : Many different chemicals are used in the everyday life, like detergents and pharmaceuticals. However, their production has a big impact on health and environment as much of the raw materials are not renewable and the standard ways of production in many cases includes toxic and environmentally hazardous components.

5. 3. Oxidation of 1,2-Diols Using Alcohol Dehydrogenases : From Kinetic Characterization to Directed Evolution

   Author : Cecilia Blikstad; Mikael Widersten; Stefan Lutz; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzyme kinetics; alcohol dehydrogenase; directed evolution; enzyme engineering; diol; α-hydroxy aldehyde; Biokemi; Biochemistry;

   Abstract : The use of enzymes as catalysts for chemical transformations has emerged as a “greener” alternative to traditional organic synthesis. An issue to solve though, is that enzymes are designed by nature to catalyze reactions in a living cell and therefore, in many cases, do not meet the requirements of a suitable biocatalyst.

6. 4. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

   Author : Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

   Abstract : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. READ MORE

7. 5. Improving Ethanol Production from Lignocellulose Hydrolyzates: Fed-batch Fermentation, Yeast Cultivation and Strain Development for Increased Tolerance

   Author : Anneli Petersson; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Saccharomyces cerevisiae; fed-batch control; Ethanol production; dilute acid hydrolyzate;

   Abstract : Ethanol production by the yeast Saccharomyces cerevisiae from dilute acid lignocellulose hydrolyzate was studied with the aim to improve fuel ethanol production. Specifically, the problem of inhibition was addressed. READ MORE
