  2. 21. Aging and heat-sealing properties of films based on wheat gluten

    Author : Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

    Abstract : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. READ MORE

    Abstract : In the past decades, stricter legislation has been imposed to improve fuel economy and to reduce tail-end emissions of automotive vehicles worldwide. One of the important and effective technologies adopted by the automobile manufacturers to fulfill legislation requirements is the turbocharger technology. READ MORE

  5. 23. Influence of heat on the physical and mechanical properties of selected rock types

    Author : Christine Saiang; Karl-Johan Loorents; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunnel fires; heat influences; temperature increase; mechanical properties; physical properties; micro cracks; mineralogy; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Impelled by the increase in the number of tunnel fires in the last decade alone, wide spread attention has been drawn towards tunnel fire safety studies. Many of these fires occurred in road and railway tunnels involving vehicles and trains. READ MORE

  6. 24. The heat is on : Evaluation of workplace heat stress under a changing climate

    Author : Karin Lundgren Kownacki; Ergonomi och aerosolteknologi; []
    Keywords : occupational heat stress; India; case studies; interventions; international standards; productivity; climate change;

    Abstract : Background: There are several scientific indications that increasing heat due to climate change is going to become the next big societal and scientific challenge. Climate change is recognized as a significant public health threat. However, there is a lack of research on its impacts on occupational safety and health. READ MORE

  7. 25. Computational Analysis of Heat Transfer and Fluid Flow with Relevance for IC-Engine Cooling

    Author : Sassan Etemad; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; turbulence models; Heat transfer; curved duct; secondary flow; IC-engine cooling; Gases; Thermal engineering; applied thermodynamics; Teknik; Technological sciences; plasma; Gaser; fluiddynamik; plasmas; fluid dynamics;

    Abstract : Modern IC-engines produce more power per displaced volume and operate at higher combustion pressures and temperatures. In addition, engine structure materials such as aluminium and magnesium alloys, which are more sensitive to thermal loads, are more commonly used. READ MORE
