  1. 1. Wheat Flour Dough-Rheological and Structural Aspects

    Författare :Helena Larsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; starch gel; gluten; water distribution; lipids; starch granule surface; starch content; mixing; ultracentrifugation; structure; rheological measurements; wheat flour dough; phase separation; ethyl hydroxyethyl cellulose; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : The thesis presents a rheological study on wheat flour dough, in relation to the structural influence of the different dough constituents, added components and mixing time. Rheological investigations have been focused on measurements at small deformations, including dynamic oscillation and stress relaxation, although complementing measurements have been performed in large deformation viscosity experiments.

  3. 2. Cross-linking and surface properties of EHEC and Starch -a QCM-D study

    Författare :Jesper Hedin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogel; GMA; HM-EHEC; Starch; vicoelastic properties; Imidazole; QCM-D; SPR; EHEC;

    Sammanfattning : The increase of the green house gases and the crude oil price has resulted in a willingness to change the raw material in many industries from petroleum-based polymers to natural polymers. One such natural polymer is starch. Today, starch is used in the glue industry in wallpaper pastes. LÄS MER

  4. 3. Transvascular exchange and organ perfusion with reference to colloid and hypertonic solutions, and to endotoxaemia

    Författare :Staffan Holbeck; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; mannitol; microdialysis; intestine; hypertonic saline; gut; hydroxyethyl starch; gelatin; endotoxin; fluid therapy; dextran; albumin; capillary filtration coefficient; intensivvård; Anestesiologi; urea; Anaesthesiology; intensive care; SIRS; reflection coefficient;

    Sammanfattning : Changes in vascular permeability can immensely change plasma volume and affect the degree of oedema in the body. In diseases with an increased vascular permeability, adequate fluid therapy is of considerable importance to prevent hypovolaemia. LÄS MER

  5. 4. Physiological and clinical aspects of change in microvascular permeability

    Författare :Johan Persson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dextran; exercise; fluid therapy; gelatin; hydroxyethyl starch; Anaesthesiology; intensivvård; intensive care; Anestesiologi; crystalloids; colloids; Albumin; Capillary filtration coefficient;

    Sammanfattning : Microvascular permeability is important for exchange of fluids and proteins in health and in disease. Permeability increases in critical illness, such as during sepsis/SIRS and after trauma, and may be affected by drugs. Increased permeability causes oedema and hypovolaemia. LÄS MER

  7. 5. Characterisation of the Substituent Distribution in Starch and Cellulose Derivatives

    Författare :Sara Richardson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Analytisk kemi; Cationic amylopectin; Hydroxypropyl amylopectin; Ethyl hydroxyethyl cellulose; Substituent distribution; Enzymic degradation; HPAEC-PAD; MALDI-TOF-MS; ESI-MS; Kemi; Analytical chemistry;

    Sammanfattning : Starch and cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution and properties is important in order to design modification processes so as to produce derivatives with the desired properties.
