2. 1. Environmental Imprint of Human Food Consumption : Linköping, Sweden 1870 - 2000

   Author : Tina-Simone Schmid Neset; Ulrik Lohm; Susanne Kytzia; Linköpings universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; food consumption; 19th and 20th century; Sweden; material flow analysis; MFA ; substance flow analysis; nitrogen; phosphorus; spatial imprint; lantbruk; miljöaspekter; livsmedelsindustri; livsmedelskonsumtion; markanvändning; Östergötland; 1800-talet; Food science; Livsmedelsvetenskap;

   Abstract : Human food consumption has changed from the late 19th century to the turn of the millennium, and so has the need for resources to sustain this consumption. For the city of Linköping, situated in southeastern Sweden, the environmental imprint of an average inhabitant’s food consumption is studied from the year 1870 to the year 2000. READ MORE

4. 2. Conformational Studies of Protein Structure and Dynamics

   Author : Dick Andersson; Franz X. Schmid; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The protein folding problem is one of the most important issues to be solved in the field of molecular biology. The subject of this thesis mainly deals with various aspects of the folding process. READ MORE

5. 3. Deformation Behaviour, Microstructure and Texture Evolution of CP Ti Deformed at Elevated Temperatures

   Author : Zhipeng Zeng; Stefan Jonsson; Hans J. Roven; Bevis Hutchinson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercially pure titanium; Zener–Hollomon parameter; Dynamic recovery; Dynamic recrystallization; Recrystallized volume fraction; Grain size; Flow stress; Constitutive equation; Texture; High angle grain boundary; Low angle grain boundary; Deformation twinning; Schmid factor; Misorientation; Hot compression; Slip system; Subgrain; EBSD; Construction materials; Konstruktionsmaterial;

   Abstract : In the present work, deformation behavior, texture and microstructure evolution of commercially pure titanium (CP Ti) are investigated by electron backscattered diffraction (EBSD) after compression tests at elevated temperatures. By analysing work hardening rate vs. flow stress, the deformation behaviour can be divided into three groups, viz. READ MORE

6. 4. Microstructure and plastic deformation of textured CVD alumina coatings

   Author : Siamak Shoja; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; α-Al2O3; Texture; Coatings; TKD; Plastic deformation; Deformation mechanisms; Electron microscopy; CVD;

   Abstract : It is known that the wear performance of α-alumina coatings produced by chemical vapor deposition (CVD) is significantly influenced by the type and degree of texture. However, the main reasons behind this behavior are not fully understood. This thesis contains studies of two related topics for increasing the understanding of α-alumina coatings. READ MORE

7. 5. Microstructure and wear mechanisms of textured CVD alumina and titanium carbonitride coatings

   Author : Siamak Shoja; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plastic deformation; Texture; TKD; Electron microscopy; Coatings; CVD; TiCN; α-alumina; Wear mechanisms;

   Abstract : The aim of this thesis is to find the reasons behind how the wear performance of hard coatings produced by chemical vapor deposition (CVD) is influenced by their texture, as this is today not fully known. Therefore, differently textured coatings were synthesized, and subsequently analyzed both before and after specially designed machining tests. READ MORE
