  4. 3. Assessment of human swallowing using in-vivo and in-vitro approaches

    Författare :Muhammad Waqas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-vitro manometery; In-vitro simulations; In-vivo analysis; microstructure analysis; extensional rheology; dysphagia; Ultrasound viscometry; Bolus Rheology;

    Sammanfattning : Texture modification is the most vital strategy to manage dysphagia: a condition in which food and beverages are difficult to swallow. Typically thickeners in the form of starch or gums are added to the food to increase the viscosity and thereby reduce the speed of bolus flow. LÄS MER

  5. 4. In-line rheology of cement grouts - Feasibility study of an ultrasound based non-invasive method

    Författare :Mashuqur Rahman; Stefan Larsson; Ulf Håkansson; Thomar Dalmalm; Lars-O Ericsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Sammanfattning : Grouting is used in underground construction to reduce the water flow into tunnels and caverns and to limit the lowering of the surrounding groundwater table. Due to their wide availability and low cost relative to other materials, cement based materials are commonly used as grouts and, in this context, the rheology of the cement grout is an important factor.
