1. 16. Studies on Translation Initiation and trans-Translation

   Författare :Serhiy Surkov; Leif Isaksson; Udo Bläsi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; ribosome; IF1; tmRNA; trans-translaton; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

   Sammanfattning :  Translation initiation factor 1 (IF1) is an essential bacterial protein, without any clearly defined function in translation initiation. Same point mutants in this protein exhibit cold-sensitivity. In addition, a sequence specific increase in test protein expression has been observed for these mutants. LÄS MER

3. 17. Detection of blade icing and its influence on wind turbine vibrations

   Författare :Sudhakar Gantasala; Jan-Olov Aidanpää; Michel Cervantes; Jean-Claude Luneno; Viktor Berbyuk; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

   Sammanfattning : Wind turbine installations in extreme conditions like cold climate have increased over thelast few years and expected to grow in future in North America, Europe, and Asia regions due to good wind resources and land availability. Their installed capacity could reach 186 GW by the end of 2020. LÄS MER

4. 18. In Search of Lost Deterrence – Two essays on deterrence and the models employed to study the phenomenon

   Författare :Karl Sörenson; Till Grüne-Yanoff; Magnus Öberg; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; Deterrence; Game Theory; Philosophy; Filosofi; Philosophy; Krigsvetenskap;

   Sammanfattning : To deter is central for strategic thinking. Some of the more astute observations regarding the dynamics of deterrence were made during the Cold War by game theorists. This set the stage for how deterrence has come to be studied. LÄS MER

5. 19. Modelling and simulation of simultaneous forming and quenching

   Författare :Greger Bergman; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Sammanfattning : The objective of this thesis is to develop and evaluate numerical methods for modelling and simulation of simultaneous forming and quenching within an integrated product development environment. Simultaneous forming and quenching, also referred to as hot-stamping, is a manufacturing process for high strength automotive components such as side impact protection beams. LÄS MER

7. 20. A Study on the Thermal State of Steelmaking Ladles

   Författare :Björn Glaser; Du Sichen; Petrus Christiaan Pistorius; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steelmaking ladle; refractory; thermal conductivity; transient hot wire method; slag; peheating;

   Sammanfattning : In the present thesis a study on the thermal state of steelmaking ladles was undertaken. The transient hot wire method was verified for thermal conductivity measurements on metallurgical slags and applied to ladle slag measurements. Temperature measurements on ladles in an industrial environment were carried out. LÄS MER
