1. 1. The Role of FCGBP in Mucus - Structure, Processing and Function

   Författare :Erik Ehrencrona; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mucus; FCGBP; IgG; IBD; COPD; Mucins; Disulphide; GDPH;

   Sammanfattning : In this thesis, a bottom-up approach was used to study the IgG Fc-binding protein (FCGBP), which next to the MUC2 mucin is the second main component of secreted mucus in small intestine and colon. FCGBP is also found in airways during inflammatory conditions with static mucus. LÄS MER

3. 2. Protein folding studies of human superoxide dismutase and ALS associated mutants

   Författare :Mikael Lindberg; Mikael Oliveberg; Jane Clarke; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; superoxide dismutase; ALS; protein folding; equilibrium titration; protein stability; apo protein; disulphide bridge; chevron plot; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

   Sammanfattning : Proteins are among the most abundant biological macromolecules. The cellular machinery is coupled to exact structural shape and properties of the more than 100 000 different proteins. Still, proteins can sometimes completely change their character and as a result trigger neuro degenerative disease. LÄS MER

4. 3. Sputtering and Characterization of Complex Multi-element Coatings

   Författare :Erik Särhammar; Tomas Nyberg; Ulf Jansson; Urban Wiklund; Gustaf Sjöblom; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thin film; coating; magnetron sputtering; modelling; tribofilm; tungsten disulphide;

   Sammanfattning : The thin film technology is of great importance in modern society and is a key technology in wide spread applications from electronics and solar cells to hard protective coatings on cutting tools and diffusion barriers in food packaging. This thesis deals with various aspects of thin film processing and the aim of the work is twofold; firstly, to obtain a fundamental understanding of the sputter deposition and the reactive sputter deposition processes, and secondly, to evaluate sputter deposition of specific material systems with low friction properties and to improve their performance.

5. 4. Formation and Function of Low-Friction Tribofilms

   Författare :Harald Skiöld Nyberg; Staffan Jacobson; Allan Matthews; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; tribofilm; PVD; coating; low-friction; tungsten disulphide; transition metal dichalcogenide; tribochemistry; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   Sammanfattning : The use of low-friction coatings on machine elements is steadily increasing, and they are expected to play an important role in the reduction of fuel consumption of future motorized vehicles. Many low-friction coatings function by transformation of the outermost coating layer into tribofilms, which then cover the coating surface and its counter surface. LÄS MER

7. 5. Light Protection in Plants: Characterisation of Violaxanthin de-epoxidase

   Författare :Erik Hallin; Biokemi och Strukturbiologi; []
   Nyckelord :violaxanthin de-epoxidase; cysteine; disulphide bond; function; pH activation; oligomerisation; circular dichroism; crosslinking; small angle x-ray scattering;

   Sammanfattning : Plants and algae need light to drive the photosynthetic machinery. An excess of light will, however, result in damage to the photosynthetic machinery and to the rest of the organism. The surplus of energy, when exposed to light stress is converted into less harmful heat energy through a process called non-photochemical quenching. LÄS MER
