  2. 21. Application of Chemical Additives in Minerals Beneficiation – Implications on Grinding and Flotation Performance

    Author : Vitalis Chipakwe; Saeed Chehreh Chelgani; Jan Rosenkranz; Tommy Karlkvist; Irina Chernyshova; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Grinding aid; Flowability; Dry grinding; FT4 Powder Rheometer; Surface properties; Rheology; Flotation; Polymers; Surface chemistry; Green Chemistry; Mineral Processing; Mineral Processing; Mineralteknik;

    Abstract : The application of chemical additives, known as grinding aids (GAs), dates to 1930 in the cement industry. Unlike the cement industry, where the use of GAs is in the final processing step, it could be one of the first processing steps in ore beneficiation. READ MORE

  4. 22. Interactions between herpes simplex virus type 1 glycoprotein C and cell surface glycosaminoglycans

    Author : Kristina Mårdberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Herpes simplex virus-1; glycoprotein C; virus receptor; glycosaminoglycans; heparan sulfate; chondroitin sulfate;

    Abstract : The cell surface glycosaminoglycan (GAG) heparan sulfate (HS) serves as an initial receptor for herpes simplex virus type 1 (HSV-1) and virus attachment to the HS molecule is mediated by the envelope glycoprotein C (gC). In the first part of this thesis, we aimed to define the HS-binding domain of viral gC. READ MORE

  5. 23. Manufacturing and Characterization of Cellulose Nanofibers

    Author : Carl Moser; Mikael Lindström; Gunnar Henriksson; Kristin Syverud; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Nanofibers; Characterization; Homogenization; Endoglucanase; TEMPO; Specific surface area; Atomic force microscopy; Cellulosa; Nanofibrer; Karakterisering; Homogenisering; Endoglukanas; TEMPO; Specifik ytarea; Atomkraftmikroskopi; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The usage of wood has been a dominant driving force during the evolution of the human species. It allowed us to cook food, build tools, put roofs over our head and explore the world. The fibers making up the tree has been the most important way to store and transmit knowledge in the form of paper for centuries. READ MORE

  6. 24. B cell activation in vitro: thymus-dependent immune responses and bacterial cell surface proteins

    Author : Karol Axcrona; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear transport; bacterial Ig-binding proteins; CD40L promoter; CD21; Ig; B lymphocyte activation in vitro; CD40; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : In this thesis aspects of peripheral B lymphocyte differentiation were studied. Through in vitro experiments, B lymphocyte activation was assessed. B lymphocytes express immunoglobulin (Ig) specific for a certain antigen on the cell surface, and when surface Ig is crosslinked by an antigen, the cell is activated. READ MORE

  7. 25. Liposomes for mucosal vaccine delivery: physicochemical characterization and biological application

    Author : Karin Norling; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoparticles; vaccine carriers; antigen presentation; dendritic cells; surface plasmon resonance; flow cytometry; liposomes; cellular uptake; fluorescence microscopy; influenza;

    Abstract : Liposomes are attractive vaccine carriers due to their potential to act as adjuvants, and to the fact that their composition and characteristics are virtually endlessly customizable. However, the precise physicochemical profile of an ideal carrier liposome for mucosal vaccines is still widely unknown, and how different properties affect key steps in the acquisition of protective immunity remains to be elucidated.
