  3. 12. Phase Distribution of Mixed Biopolymer Gels in Relation to Process Conditions

    Författare :Pernilla Walkenström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gelatin; whey protein; phase distribution; shear; high pressure; rheological properties; microstructure; mixed gels;

    Sammanfattning : The influence of various process parameters on the microstructure and rheological properties of pure and mixed gels of gelatin and whey proteins has been investigated. Gelatin is a cold-set protein and whey proteins are a group of thermo-set globular proteins. Depending on the charge present, whey proteins can form two types of gel structures. LÄS MER

  4. 13. Analysis of Transvascular Transport Phenomena in the glomerular and peritoneal microcirculation

    Författare :CARL ÖBERG; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal dialysis; glomerular filtration barrier; pore model; automated peritoneal dialysis APD ; three-pore model;

    Sammanfattning : The current work is devoted entirely to the study of passive transport phenomena, or more specifically, the more simple diffusion, electric migration and filtration of solute matter and water over glomerular and peritoneal capillary walls. The driving forces behind such trans-capillary transport phenomena have long been assumed to be simple gradients of concentration, hydrostatic pressure and electric potential. LÄS MER

  5. 14. Pharmaceutical binders and their function in directly compressed tablets : Mechanistic studies on the effect of dry binders on mechanical strength, pore structure and disintegration of tablets

    Författare :Sofia Mattsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Compaction; tablet; binder; pore structure; disintegration; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. LÄS MER

  7. 15. Critical degrees of saturation at freezing of porous and brittle materials

    Författare :Göran Fagerlund; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resistance; freezing mechanism; freezing test method; pore size distribution determination ; saturation degree of ; water absorption; frost;

    Sammanfattning : This thesis is based on experimental work carried out during the period 1968-1972. The whole investigation is sponsored by the Swedish Council for Building Research and has been performed at the department of Building Materials at the Lund Institute of Technology. LÄS MER
