1. 16. Experimental and modelling studies of particle radiation in flames

   Författare :Daniel Bäckström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Combustion of solid fuels is an important part of many industrial and power generation processes. The global use of coal in these processes is vast and thus also the related emissions of CO2 to the atmosphere. It is not possible to continue on the path with continuously increasing emissions of CO2 if the global climate targets should be met. LÄS MER

3. 17. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

   Författare :Jürgen Salay; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; implementation; sustainable energy; renewable energy; electricity production; power industry; Baltic states; Poland; transition; sulphur dioxide; air pollution; energy efficiency; Energy; energy use; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Energy research; Energiforskning;

   Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

4. 18. A pressure coupled Representative Interactive Linear Eddy Model (RILEM) for heavy-duty truck engine combustion simulations

   Författare :Nidal Doubiani; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Representative interactive linear eddy model; multiple LEM lines; turbulent chemistry interaction; pressure coupling; pollutants formation.;

   Sammanfattning : Internal combustion engines (ICE) are frequently debated due to their environmental consequences. Although the switch to electromobility is currently happening for light and medium-duty vessels, the transition for ships and heavy-duty trucks is more complex. The primary problem in the shift is the incapability of matching the range of ICE. LÄS MER

5. 19. There's Plenty of Room in Higher Dimensions - Nonlinear Dynamics of Nanoelectromechanical Systems

   Författare :Martin Eriksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonresonant actuation; quantum dots; NEMS; internal resonance; superconductivity; nonlinear dynamics;

   Sammanfattning : Nanoelectromechanical systems (NEMS) couple the dynamics of electrons to vibrating nanostructures such as suspended beams or membranes. These resonators can be used in for instance nanoelectronics and sensor applications. NEMS are also of fundamental interest since electrons exhibit strong quantum effects when confined in nanoobjects. LÄS MER

7. 20. The Structural Modularity and Inherent Dynamics of the DegP Protease together with its Intertwined Role in the Bacterial Periplasm

   Författare :Darios Šulskis; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; serine protease; DegP; nuclear magnetic resonance; E. coli; protein quality control; chaperone; HtrA;

   Sammanfattning : The protein quality control machinery is a delicate and integrated network of molecular tools working together to fold or remove unwanted proteins from the cell. A distinct set of “gatekeepers” are involved in this process including molecular chaperones, proteases, oxidoreductases, transferases, and many others in both eukaryotic and prokaryotic organisms.
