  2. 6. Trehalose metabolism and stress resistance in Aspergillus niger

    Author : Åsa Svanström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Food spoilage by filamentous fungi, moulds, is a global issue of great significance. Mould growth can cause food losses due to deterioration, and adverse health effects due to toxin production. Conidia, asexual spores, are the main factors of dispersal and infection in most food-relevant moulds. READ MORE

  4. 7. Microstructure and Properties of Additively Manufactured Tool Steels for Hot Stamping

    Author : Miwen Yuan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Steels; Wear; Hot stamping; Additive Manufacturing; Softening Resistance;

    Abstract : Hot work tool steels are commonly used to produce dies for hot stamping, where the steels are exposed to cyclic thermal and mechanical loads. There is a constant demand to improve the lifetime of the dies. Additive manufacturing (AM) provides new solutions for tool design. READ MORE

  5. 8. Analysis of heat transfer and fluid flow in the resin transfer moulding process

    Author : Rikard Gebart; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : This thesis contains an analysis of fluid flow and heat transfer problems in the resin transfer moulding (RTM) process for manufacturing of polymer based fibre composites and it consists of five separate papers. The permeability of unidirectional fabrics, that are often used in advanced composites, is considered in Paper A and a theory for the permeability dependence on the micro geometry is developed.

  6. 9. Microengineering of diamond

    Author : Henrik Björkman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Performance of micromechanical systems often relies on extreme material properties. Being the strongest, stiffest and hardest of all materials, exhibiting extreme electromagnetic transparency and wear resistance, and offering the highest possible thermal conductivity and very low friction against most materials, diamond is indeed a unique material.

  7. 10. Evaluating building envelopes for energy efficient buildings : Energy- and moisture performance considering future climate change

    Author : Björn Berggren; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Buildings account for a signifi cant proportion of the energy use thatgenerates greenhouse gases and consequently drives the ongoing climatechange. As the population of the world increases, the need for buildingsincreases, while the energy use needs to decrease. READ MORE
