  1. 1. Short-chain dehydrogenases/reductases : structure, function and motifs of hydroxysteroid dehydrogenases

    Författare :Charlotta Filling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Short-chain dehydrogenases reductases; site-directed mutagenesis; steady-state kinetics; X-ray structure; enzyme function; steroid; motif; reaction mechanism; 3 beta 17 beta-hydroxysteroid dehydrogenase; 17 beta-hydroxysteroid dehydrogenase; short chain hydroxyacyl coenzyme A dehydrogenase;

    Sammanfattning : Short-chain dehydrogenases/reductases (SDR) constitute a superfamily of proteins catalysing reactions of a wide range of substrates in all life forms. During the past years, a large number of new proteins belonging to this superfamily has been detected. They are important in e.g. LÄS MER

  3. 2. A study of flow fields during filling of a sampler

    Författare :Zhi Zhang; Pär Jönsson; Dongyuan Sheng; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physical modeling; flow pattern; vortex; filling; PIV; sampler; simulation; turbulence; Wilcox k-ω model; Materials science; Teknisk materialvetenskap; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : More and more attention has been paid to decreasing the number and size of non-metallic inclusions existing in the final products recently in steel industries. Therefore, more efforts have been made to monitor the inclusions' size distributions during the metallurgy process, especially at the secondary steelmaking period. LÄS MER

  4. 3. A Study of the Initial Mould Filling during Up-hill Ingot Casting

    Författare :Line Hallgren; Pär Jönsson; Anders Tilliander; Seppo Louhenkilpi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; up-hill teeming; nozzle; casting; fluid flow; modelling; CFD; LDA; swirl; ingot casting; filling; red eye;

    Sammanfattning : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. LÄS MER

  5. 4. Free View Rendering for 3D Video : Edge-Aided Rendering and Depth-Based Image Inpainting

    Författare :Suryanarayana Murthy Muddala; Mårten Sjöström; Roger Olsson; Christine Guillemot; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3DV; 3DTV; FTV; view rendering; depth-image-based rendering; hole-filling; disocclusion filling; inpainting; texture synthesis; view synthesis; layered depth image;

    Sammanfattning : Three Dimensional Video (3DV) has become increasingly popular with the success of 3D cinema. Moreover, emerging display technology offers an immersive experience to the viewer without the necessity of any visual aids such as 3D glasses. LÄS MER

  7. 5. On root-filling quality in general dental practice

    Författare :Lisbeth Dahlström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; root-filling quality; nickel-titanium rotary instrumentation; implementation; hands-on; social network; focus groups; qualitative content analysis; general dental practitioners; stress;

    Sammanfattning : In Sweden, 250,000 root fillings are performed every year. The outcome of root canal treatment (RCT) is strongly correlated to the technical quality of the root filling. Epidemiological studies show high frequencies of suboptimal technical quality. LÄS MER
