  1. 1. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    Author : Nabil Khoshaba; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Abstract : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. READ MORE

  2. 2. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics

    University dissertation from Stockholm : KTH

    Author : Lars-Erik Enarsson; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte adsorption; adsorption kinetics; adsorption isotherms; conformation; bridging; stagnation point adsorption reflectometry; quartz crystal microgravimetry; polyelectrolyte titration; cationic polyacrylamide; cationic dextran; colloidal silica; silica surfaces; pulp; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : Denna avhandling presenterar experimentella studier av polyelektrolytadsorption på motsatt laddade ytor, där substrat av både kiseloxid och blekt barrsulfatmassa har använts. Ett huvudsakligt syfte med denna forskning var att karaktärisera konformationen hos adsorberade skikt av katjonisk polyakrylamid (CPAM) i jämförelse med katjonisk dextran (Cdextran) och relatera denna information till inbindningskapaciteten av kolloidal kiselsyra.

  3. 3. Volume kinetics of glucose solutions given by intravenous infusion

    University dissertation from Stockholm : Karolinska Institutet, Karolinska Institutet, Stockholm Söder Hospital

    Author : Fredrik Sjöstrand; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Volume kinetics; osmosis; dehydration; rehydration; glucose solutions; glucose; hypovolemia; hypoglycemia; fluids; intravenous fluid therapy; fluid shifts; plasma volume; dilution; plasma dilution; intracellular hydration; central volume.;

    Abstract : Fluid therapy is often cumbersome to plan since the distribution and the elimination of the administered solution are difficult to analyze in the clinical setting. The knowledge of the adequate rate and dose for each individual patient and under various physiological conditions would be very attractive to obtain in order to avoid fluid overload and hyperglycemia.

  4. 4. Study and Modeling of the Reduction of Sulfur Dioxide, Nitrogen Oxides and Hydrogen Chloride by Dry Injection Technologies

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Wuyin Wang; Lunds universitet.; Lund University.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reaction kinetics; pore particle size; HCl; NOx; desulfurization; Ca-based sorbent; flue gas; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : The potential and mechanism to reduce acid gases, such as SO2, NOx and HCl by dry Ca-based sorbents have been studied to improve the efficiencies of the process and sorbent utilization. Several natural limestones were tested for SO2 removal. Calcium conversion as high as 45% was achieved within 0.3 s at 1000°C, 1000 ppm SO2 and Ca/S=1. READ MORE

  5. 5. Towards Understanding of Selectivity & Enantioconvergence of an Epoxide Hydrolase

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Åsa Janfalk Carlsson; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; Epoxide; Enantioselectivity; Regioselectivity; Enantioconvergence; Crystal structures; Biocatalysis; Immobilization; Transient kinetics; CASTing; Directed evolution; Biokemi; Biochemistry;

    Abstract : Epoxide hydrolase I from Solanum tuberosum (StEH1) and isolated variants thereof has been studied for mapping structure-function relationships with the ultimate goal of being able to in silico predict modifications needed for a certain activity or selectivity. To solve this, directed evoultion using CASTing and an ISM approach was applied to improve selectivity towards either of the enantiomeric product diols from (2,3-epoxypropyl)benzene (1). READ MORE
