1. 11. Controlling protein homeostasis through regulation of Heat shock factor 1

   Författare :Anna E. Masser; Claes Andréasson; Marie Öhman; David Pincus; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stress; protein homeostasis; molecular chaperones; heat shock response; Hsf1; Hsp70; Saccharomyces cerevisiae; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : In order to thrive in a changing environment all organisms need to ensure protein homeostasis (proteostasis). Proteostasis is ensured by the proteostasis system that monitors the folding status of the proteome and regulates cell physiology and gene expression to counteract any perturbations. LÄS MER

3. 12. Limiting conditions for a sustained flame over condensed fuels : Analysis by experiments and stagnant layer theory

   Författare :Frida Vermina Plathner; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Critical mass flux; diffusion flame; extinction; sustained ignition; chemical heat of combustion; Convective heat transfer coefficient; external heat flux;

   Sammanfattning : Ignition and extinction characteristics of a material determine whether a fire will be initiated and grow. In fire safety engineering, where modellers deal with a multitude of materials, simplified thresholds are commonly used to determine when ignition and extinction occur. LÄS MER

4. 13. Knock in Gasoline Engines - the Effects of Mixture Composition on Knock Onset and Heat Transfer

   Författare :Börje Grandin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SI engines; knock; heat transfer; thermal-boundary layer; cooled EGR; coherent anti-Stokes Raman spectroscopy CARS ; autoignition;

   Sammanfattning : This thesis is based on experimental investigations into engine knock in, (a) a multi-cylinder turbocharged engine, and (b) a single-cylinder engine featuring optical access. The optical access facilitated the measurement of temperature in the end-gas using coherent anti-Stokes Raman spectroscopy (CARS). LÄS MER

5. 14. Study of heat release rates of mining vehicles in underground hard rock mines

   Författare :Rickard Hansen; Haukur Ingason; Nicholas Dembsey; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : A unique study on fire safety in hard rock underground mines with focus on heat release rates of mining vehicles is presented. A literature inventory was conducted with respect to fires in underground hard rock mines, which revealed that the most common fire cause in underground mines was flammable liquid sprayed onto hot surface and the most common fire object was a vehicle.

7. 15. New process integration methods for heat-saving retrofit projects in industrial systems

   Författare :Roger Nordman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Process Integration; Heat Exchanger Network; Pulp and Paper; Method Development;

   Sammanfattning : New graphical methods for HEN retrofit (further development of existing tools), release of usable excess heat and placement of supply tanks in HWWS systems have been developed. In addition, further development of the matrix method for HEN retrofit has been made. LÄS MER
