  2. 1. Patch clamp and calcium studies on human colonic mucosal cells

    Author : Peter Sand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Human; colon crypt; HT29; K channel; Ca oscillations; volume regulation; patch clamp;

    Abstract : Background: The main function of the large intestine is to fine-tune electrolyte and water balance. This is achieved through the consorted action of ion channels, transporters and pumps. Failures of this system can lead to diarrhoea. READ MORE

  4. 2. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders

    Author : Mirja Rothhämel; Jan Laue; Sven Knutsson; Craig Lake; Luleå tekniska universitet; []

    Abstract : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. READ MORE

  5. 3. AIR CLASSIFICATION OF FINE AGGREGATES

    Author : Robert Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Fines; Manufactured sand; Aggregates; Air classification; Concrete;

    Abstract : Aggregates are defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregates for concrete production in Sweden. READ MORE

  6. 4. Modelling of Groundwater Conditions in Silts and Fine Sands. A Study of Induced Groundwater Changes Based on Laboratory and Full-Scale Field Tests

    Author : Marius Tremblay; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fine sand; laboratory tests; numerical simulation; silt; soil mechanics; groundwater; pore pressure; field tests; soil matric suction; partially saturated soil; groundwater conditions;

    Abstract : Every day, geotechnical engineers have to deal with groundwater problems. In order to find suitable solutions to these problems, modelling of the groundwater conditions and their variations in time has to be performed. A study of the groundwater conditions in silts and fine sands was made including laboratory and full-scale field tests. READ MORE

  7. 5. Compaction- and strength properties of stabilised and unstabilised fine-grained tills

    Author : Per Lindh; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Väg- och vattenbyggnadsteknik; Compaction; Fine-grained tills; Strength; Civil engineering; Soil stabilisation modification; hydraulic engineering; soil mechanics; offshore technology; Material technology; Materiallära; materialteknik;

    Abstract : Fine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. READ MORE
