  2. 1. Dicarboxylic acids from xylose, using natural and engineered hosts

    Author : Henrik Almqvist; Avdelningen för kemiteknik; []
    Keywords : Xylose; Dicarboxylic Acids; Biorefineries; Actinobacillus succinogenes; Basfia succiniciproducens; Saccharomyces cerevisiae; Caulobacter crescentus;

    Abstract : Chemical building blocks for plastics can be produced from renewable biomass feedstocks using microbial production organisms, such as yeast or bacteria, in a biorefinery. One class of chemical building blocks that are suitable for production of biobased and biodegradable plastics are dicarboxylic acids, e.g. succinic acid. READ MORE

  4. 2. Numerical simulation of elastohydrodynamic and hydrodynamic lubrication using the Navier-Stokes and Reynolds equations

    Author : Torbjörn Almqvist; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The work presented in this thesis concerns computer simulations of the lubrication process. The main subject of interest is elastohydrodynamic lubrication (EHL) and, to some extent, hydrodynamic lubrication (HD). The thesis comprises an introductory section and three papers; referred to as A, B and C. READ MORE

  5. 3. The role of exosomes and microflora in establishing mucosal tolerance and the protection against allergic disease

    Author : Nina Almqvist; Göteborgs universitet; []
    Keywords : oral tolerance; exosomes; allergy;

    Abstract : The role of exosomes and microflora in establishing mucosal tolerance and the protection against allergic disease Nina Almqvist, Departement of Rheumatology and Inflammation Research, The Sahlgrenska Academy University of Gothenburg, Guldhedsgatan 10A, 413 46 Göteborg, Sweden The breakdown of immune regulation to innocuous environmental antigens at mucosal sites can result in a number of different diseases such as, allergies and inflammatory bowel disease (IBD). Allergy is one of the most common diseases with a prevalence of up to 40% in children from developed countries. READ MORE

  6. 4. Lipase catalysed reactions of terpenoids : formation of hemiacetal esters : resolution of cryptone and its transformation to cadinenes

    Author : Dan Isaksson; Fredrik Almqvist; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; terpenoid; lipase; resolution; hemiacetal; hemiacetal ester; enantioselective; synthesis; cryptone; cadinene; Organic chemistry; Organisk kemi;

    Abstract : During attempted enzyme-catalysed resolution of sterically hindered secondary alcohols, hemiacetals and their esters were unexpectedly detected. Hemiacetal esters are reactive compounds that decompose to alcohol, aldehyde and acid under ordinary work-up conditions i.e. in contact with water, acid, or silica gel. READ MORE

  7. 5. Design & Synthesis of Protein Interacting Affinity Ligands and Protease Inhibitors

    Author : Charlotta Lindquist; Hans Adolfsson; Fredrik Almqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : There is a growing need of both protein drugs and synthetic drugs in the fight against many life-threatening diseases. The first part of this thesis deals with the design and synthesis of high affinity binding ligands for the purification of protein drugs. READ MORE
