2. 1. Lipid-related genes and their associations with coronary heart disease

   Author : Ci Song; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Coronary heart disease (CHD) is a complex disease caused by the long-term progression of atherosclerosis. Lipids, including high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) are well established biomarkers for CHD, and are used to predict individual 10-year risk for CHD both in the Framingham risk score and in the System for Cardiac Operative Risk Evaluation (SCORE) project.

4. 2. Condition monitoring of railway vehicles : a study on wheel condition for heavy haul rolling stock

   Author : Mikael Palo; Thomas Robertsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : A railway is an energy efficient mode of transport as it uses the low resistance contact between wheel and rail. This contact is not frictionless and causes wear on both surfaces. The wheel-rail guidance is made possible by the shapes of wheel and rail profiles. READ MORE

5. 3. Protection of Complex Infrastructure Systems against Intentional Electromagnetic Interference

   Author : Per Ängskog; Daniel Månsson; Per Näsman; Farhad Rachidi-Haeri; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IEMI; CI; EMP; Critical Infrastructure; Electromagnetic Interference; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis the effects of, and defense against, antagonistic attacks using Intentional Electromagnetic Interference (IEMI) are treated; especially when targeting infrastructure critical to society (CI).IEMI as a means to disturb or destroy electronic equipment draws its roots from military methods to interrupt or interfere with enemy activities.

7. 5. The effects of long chain alcohol blends on engine performance and spray characteristics in CI engines

   Author : Josefine Preuss; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray characteristics; RME; drop-in bränslen; long chain alcohols; CI engine; HVO;

   Abstract : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.
