  2. 21. Lipase-catalyzed production of structured triacylglycerols

    Author : Ariana Causevic; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structured lipids; Lipase; Acyl migration; Immobilization; Lipid analysis; Transesterification; Water activity;

    Abstract : Vegetable oils and fats are major energy sources but also play an essential part in the physical and chemical properties of food products. The current change in the climate is affecting harvest yields, leading to a shortage and increased prices of raw materials that are difficult to replace. READ MORE

  4. 22. Nucleic Acids as Drug Targets -Interactions of Platinum Complexes, Polyamines, and siRNA with DNA and RNA Models

    Author : Margareta Hägerlöf; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kinetics; Kemi; Chemistry; AU-rich region; siRNA; Circular Dichroism; Polyamine; Modified Nucleoside; HPLC; Thermodynamic Stability; cisplatin; Hairpin; DNA and RNA conformation; RNA; DNA; Anticancer Drug; Platinum Complexes;

    Abstract : Drugs targeting nucleic acids were studied in DNA and RNA model systems. The effects were investigated with respect to structural and thermodynamic influence, kinetics, and biological function. The drugs employed in this thesis were anticancer active platinum(II) complexes, polyamine derivatives, and siRNA. READ MORE

  5. 23. The Effect of Ladle Treatment on Steel Cleanness in Tool Steels

    Author : Karin Steneholm; Pär Jönsson; Guozhu Ye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen activity; inclusion characteristics; vacuum degassing; desulphurization; slag; ladle; hydrogen; nitrogen; deslagging; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The aim of the present work was to get an overview of the steel cleanness in tool steel. Plant trial studies of three steel grades were done with different focuses.Firstly the change of the inclusion characteristics during the vacuum degassing in the ladle was looked upon. READ MORE

  6. 24. A study of slag-steel-inclusion interaction during Ladle treatment

    Author : Johan Björklund; Pär Jönsson; Voicu Brabie; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ladle treatment; steel; slag; inclusions; ladle; refining; vacuum; tool steel; oxide activity; slag models; oxygen; equilibrium; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. READ MORE

  7. 25. Engineering Antibody Specificity Using Combinatorial Antibody Libraries

    Author : Jenny Boström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antibody Antigen Interactions; Dual Specific Antibodies; Herceptin; Human Epidermal Growth Factor Receptor 2; Thermodynamic Analysis; therapeutic Antibody Engineering; Synthetic Phagedisplayed Antibody Libraries; Vascular Endothelial Growth Factor; Bacterial Display; trastuzumab;

    Abstract : The research presented in this thesis investigates antibody specificity, antibody-antigen and protein-protein interactions using combinatorial antibody libraries, phage-display and bacterial display technology. One goal was to develop a method to generate antibodies that bind two protein antigens with high affinity using a single-antigen binding site, and to investigate the molecular and thermodynamic requirements for antibody multispecificity.
