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

    Author : Charlotta Filling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Externally positive systems : Analysis and control based on combinatorial polynomials

    Author : Liam Hamed Taghavian; Mikael Johansson; Cristian R. Rojas; Fabio Pasqualetti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear systems; External positivity; Optimization; Non-overshooting control; Combinatorics; Complete monotonicity; Majorization.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Monotonic tracking is required in many control systems, including those that cannot tolerate any overshoots and undershoots in their closed-loop responses. Classical examples are found in vehicle cruise control and liquid tank level control. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. A Model System for Powder Injection Moulding – Physical Properties and Mould Filling Analysis

    Author : Henrik Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; processing conditions; thermal properties; computer simulations; rheology; powder injection moulding; mould filling; jetting;

    Abstract : ABSTRACTPowder injection moulding (PIM) is an important and accepted industrial technique for producing net-shaped components which combines the advantages of injection moulding and powder metallurgy. The properties of the feedstock, a mixture of powder and binder system (often based on a thermoplastic polymer), strongly influence the process. READ MORE

  7. 5. Enantiomeric separation by capillary electrophoresis : With special emphasis on the partial filling technique

    Author : Ahmad Amini; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Abstract : Capillary electrophoresis as a powerful separation technique was employed for resolution of racemic drugs. Taurodeoxycholate (TDC), different cyclodextrins and α1- acid glycoprotein (AGP) were dissolved in the background electrolyte at low pH (3.0 to 4.0 ) as chiral selectors. READ MORE
