2. 21. Studies of genetic mosaicism in rare diseases

   Author : Sofia Frisk; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Mosaicism in human genetics refers to an individual harboring two or more genetic compositions, all derived from the same fertilized egg. Common signs of genetic mosaicism are asymmetric growth, skin aberrations or vascular malformations. READ MORE

4. 22. Electrical Charges on Polymeric Insulator Surfaces and their Impact on Withstand Performance

   Author : Sarath Kumara; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impulse corona; Surface charge; impulse flashover voltage; corona charging; streamer criterion; surface potential decay; charge relaxation;

   Abstract : Use of polymeric materials for high voltage outdoor insulation systems is increasing continuously. Insulating polymers gradually replace traditional materials like porcelain and glass and become dominant at ultra high voltages, e.g., in 1000 kV ac and 800 kV dc overhead power transmissions, which are presently being developed.

5. 23. Essays on Environmental Economics

   Author : Erika Budh; Lars Hultkrantz; Chuan-Zhong Li; Ing-Marie Gren; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Environmental economics; public good; public bad; negative externality; voluntary contribution; experiment; envionmental objectives; multiple emission reductions; sub-optimization; linear programming; multivariate stochastic control; emission trading; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

   Abstract : This dissertation consists of four self-contained essays.Essay IThis essay reports on an experimental study of how voluntary contributions in a public good game are affected by framing. In the public good context, average wealth improves from contributions. In the defensive contexts, the voluntary contributions prevent reductions in average wealth. READ MORE

6. 24. Adhesion in the wheel-rail contact under contaminated conditions

   Author : Yi Zhu; Ulf Olofsson; Ines Lopez Arteaga; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesion; wheel-rail contact; contaminants; rough surfaces;

   Abstract : Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. READ MORE

7. 25. Characterization of Electrodeposited Fe-based Metallic Coatings: Toward a Sustainable Approach

   Author : Antonio Mulone; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrodeposition; structural characterization; coatings; electrodeposited tin; iron alloys;

   Abstract : Electrodeposition has rapidly grown in the last 50 years and it has been applied to deposit metals and alloys with complex shapes or to produce fully dense nanostructures and amorphous coatings. Thanks to the achieved improved properties of the electrodeposited materials, electrodeposition has been applied in a wide set of applications including protective coatings, and magnetic and electronic applications.
