  1. 1. On the Modelling of Mechanical Dewatering in Papermaking

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Vinicius Lobosco; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; paper; modelling; dewatering; forming; wet pressing; fibre network stress; rheology; hysteresis; intra-fibre water; compressibility; structural stress; stress-strain; restricted gels; swelling;

    Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

  2. 2. An Investigation of Thermogelling Aqueous Systems of Ethyl(HydroxyEthyl)Cellulose and Ionic Surfactants

    University dissertation from Department of Food Technology, Lund University

    Author : Katarina Lindell; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer-polymer association; HS-DSC; SANS; solubilization; dexamethasone; timolol maleate; in vitro release; thermoreversible gelation; phase diagram; cloud point; Ethyl hydroxyethyl cellulose; ionic surfactants; Livsmedelsteknik; Food and drink technology;

    Abstract : Aqueous solutions of a particular type of the nonionic cellulose derivative ethyl(hydroxyethyl)cellulose (EHEC) may form thermoreversible gels in the presence of ionic surfactants. Low-viscous solutions can be transformed to clear, stiff gels as the temperature is increased. READ MORE

  3. 3. Phase Separation and Gelation of Biopolymers in Confined Geometries

    University dissertation from Department of Food Technology, Lund University

    Author : Sophia Wassén; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; spinodal decomposition; confocal laser scanning microscopy; gelatin–maltodextrin; whey protein isolate–gellan gum; image analysis.; microstructure; confinement; biopolymer mixture; phase separation; structure evolution;

    Abstract : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. READ MORE

  4. 4. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers

    University dissertation from SIK - Svenska Livsmedelsinstitutet

    Author : Gisela Richardson; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; image analysis.; rheology; microscopy; amylose-lipid complex; gelatinization; dynamical arrest; amylose; starch; sponge cake; foam; emulsifier; alpha-gel; physical state;

    Abstract : Popular Abstract in Swedish I bageriindustrin används emulgatorer i så kallad alfaform för att tårtbottnar ska kunna vispas i ett steg och ändå få en stor luftvolym. Avhandlingen fokuserar på vissa av emulgatorns effekter i produkter såsom kaksmet: Hur skumbildningen påverkas av emulgatormolekylernas packning, hur emulgatorer ändrar svällningen av stärkelsekornen i mjölet, och vilka effekterna blir i den verkliga produkten.

  5. 5. Mammalian brain acetylcholinesterase a study of its solubilization, purification, molecular state and interactions with cholinergic ligands including an endogenous modulator

    University dissertation from Umeå : Umeå universitet

    Author : Bertil Niklasson; Umeå universitet.; [1981]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affinity chromatography; caudate nucleus; acetylcholinesterase; tetracaine; décaméthonium; d-tubocurarine; edrophonium; fluoride ion; hysteric properties; endogenous ligands to AChE;

    Abstract : Membrane bound AChE from calf brain caudate nucleus was solubilized by use of ion-free media in presence of 10~ M EDTA and 10“5M tetracaine. The irreversible release of AChE was more effectively inhibited by divalent ions compared to monovalent ions added to the medium. READ MORE
