1. 6. On the Mechanisms behind the Tribological Performance of Stellites

   Författare :Daniel H. E. Persson; Sture Hogmark; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Stellite; Co-based; phase transformation; fcc; hcp; texture; alignment; low-friction; laser cladding; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : This thesis reveals the tribological mechanisms behind the intrinsic low friction potential of the Co-based family of alloys called Stellites. Although being an established and important group of materials, a satisfactory explanation to why they exhibit low-friction properties under severe sliding conditions has not previously been found in the literature.

3. 7. Styrelseledamöters skyldigheter och ansvar vid risk för obestånd och liknande situationer

   Författare :Karin Blad; Eleonor Kristoffersson; Stefan Olsson; Annina H. Persson; Ingrid Arnesdotter; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; insolvens; obestånd; styrelseledamot;

   Sammanfattning : Styrelseledamöter har ett antal skyldigheter när ett aktiebolag får ekonomiska svårigheter. Vilka regler som aktualiserar bolagsledningens ansvar beror på om ett aktiebolag har betalningsproblem eller balansproblem. Avseende balansproblemet finns regler om så kallat medansvar för styrelseledamöter och andra företrädare i 25 kap. LÄS MER

4. 8. The Plant Plasma Memrbane H+-ATPase: regulation by phosphorylation and 14-3-3 proteins

   Författare :Anne Olsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphorylation; fusicoccin; 14-3-3; C-terminus; autoinhibitory domain; plasma membrane; plant; H -ATPase; Plant biochemistry; Växtbiokemi;

   Sammanfattning : The plant plasma membrane H+-ATPase is a predominant membrane enzyme that provides the energy for secondary active transport across the plasma membrane. Consequently, the H+-ATPase is thought to play a major role in many cell processes, and it is implicated to be regulated by a number of factors, including hormones, blue light, and fungal toxins The plant plasma membrane H+-ATPase is regulated via an autoinhibitory domain located within the C-terminal region of the enzyme.

5. 9. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism

   Författare :Daniel Olsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organometallic chemistry; Metallorganisk kemi; Organic chemistry; Oorganisk kemi; Inorganic chemistry; Suzuki reaction; Stille reaction; catalysis; cyclometalation; C-H activation; PCP complex; POCOP ligand; PCP ligand; iridium; palladium; platinum;

   Sammanfattning : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. LÄS MER

7. 10. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging

   Författare :Roger Olsson; Youzhi Xu; Mårten Sjöström; Tingting Zhang; Aljoscha Smolic; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integral Imaging; 3D images; coding; quality evaluation; H.264 AVC; JP3D; Telecommunication; Telekommunikation;

   Sammanfattning : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. LÄS MER
