  1. 1. Dynamic Modelling and Simulation of Liquid Food Process Lines

    Författare :Tomas Skoglund; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process lines; Dynamic model; Microbial deactivation; Data- och systemvetenskap; computer technology; Systems engineering; Fuzzy traceability; Traceability; Thermal engineering; termodynamik; Termisk teknik; applied thermodynamics; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Heat exchanger; Dispersion; Fluid property transition; Liquid food; Dynamic simulation; Livsmedelsteknik;

    Sammanfattning : In the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers.

  3. 2. Chemoattractant receptor signaling and neutrophil acctivation. Involvement of the cytoskeleton

    Författare :Huamei Fu; Göteborgs universitet; []
    Nyckelord :neutrophils; G-protein coupled receptors; signaling; cytoskeleton;

    Sammanfattning : Neutrophil granulocytes play a vital role in the host surveillance system and form the first line of defense against microbial infections. The migration of neutrophils to an infected/inflamed tissue is guided by chemoattractants released either from intruding microbes or from activated/damaged host cells. LÄS MER

  4. 3. Oxidation of Ketones: A (Chemo-) Enzymatic Approach Using Oxygenases and Hydrolases

    Författare :Georgina Chávez; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross linked enzyme aggregates.; caprolactone; perhydrolase; Lipase B from Candida antarctica;

    Sammanfattning : Oxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage.

  5. 4. Improvement of Wastewater Sludge Digestion

    Författare :Michael Recktenwald; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

    Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER
