  2. 6. Methodology for high-throughput production of soluble recombinant proteins in Escherichia coli

    Author : Katrin Markland; Gen Larsson; Pär Nordlund; Jenny Ottosson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; high-throughput methodology; recombinant protein production; solubility; productivity; quality; cultivation technology; parallel reactors; Biochemistry; Biokemi;

    Abstract : The aim of this work was to investigate and determine central parameters that can be used to control and increase the solubility, quality and productivity of recombinant proteins. These central parameters should be applicable under the constraints of high-throughput protein production in Escherichia coli. READ MORE

  4. 7. Quality of muscle foods : effects of feed and storage time

    Author : Shengjie Li; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The overall aim of this thesis was to investigate the effects of feed and storage time on meat quality. To study the effect of feed, chicken were fed seven steam-pelleted or nonpelleted rapeseed (RS) diets with different RS inclusion levels (0, 80, 160, and 240 g/kg) for 34 days, and the dietary effects on meat yield, fatty acid composition in meat, and the expression of lipid metabolism-related genes in liver were determined.

  5. 8. Bringing predictability into a geometallurgical program : An iron ore case study

    Author : Viktor Lishchuk; Bertil Pålsson; Cecilia Lund; Pertti Lamberg; Jennifer Broadhurst; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additivity; Apatite iron ore; AIO; Block model; Change of support; Classification; Data integration; DT; Feed quality; Geometallurgical program; Geometallurgy; Iron ore; Iron recovery; Leveäniemi; Liberation; Machine learning; Magnetic separation; Malmberget; Mineralogical approach; Mineralogy; Prediction; Proxies; Proxies approach; Sampling; Simulation; Synthetic ore body; Traditional approach; WLIMS; Mineral Processing; Mineralteknik;

    Abstract : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. READ MORE

  6. 9. Rapid sample preparation and bioanalytical techniques for efficient screening of organic pollutants in the environment

    Author : Malin Nording; Peter Haglund; Ron Hoogenboom; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accelerated solvent extraction; CAFLUX; food; immunoassay; PAH; PCDD; PCDF; pressurized liquid extraction; soil; CALUX; cell-based bioassay; chemically activated fluorescent gene expression; chemically activated luciferase gene expression; dioxin; ELISA; enzyme-linked immunosorbent assay; feed; Environmental chemistry; Miljökemi;

    Abstract : Large numbers of samples often need to be prepared and analysed in surveys of organic pollutants in the environment, but while the methods commonly used in such surveys can provide abundant detail they are generally costly, time-consuming and require large amounts of resources, so there is a need for simpler techniques. The work underlying this thesis assessed the potential utility of more convenient sample preparation and bioanalytical techniques for rapidly screening various environmental matrices that could be useful complements to higher resolution methods.

  7. 10. Quality-Driven Production of Aggregates in Crushing Plants

    Author : Magnus Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breakage; crushing; simulation; modelling; Keywords: aggregate quality; particle shape;

    Abstract : Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. READ MORE
