1. Patch clamp and calcium studies on human colonic mucosal cells
Sammanfattning : 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. LÄS MER
2. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders
Sammanfattning : 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. LÄS MER
3. AIR CLASSIFICATION OF FINE AGGREGATES
Sammanfattning : 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. LÄS MER
4. Modelling of Groundwater Conditions in Silts and Fine Sands. A Study of Induced Groundwater Changes Based on Laboratory and Full-Scale Field Tests
Sammanfattning : 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. LÄS MER
5. Compaction- and strength properties of stabilised and unstabilised fine-grained tills
Sammanfattning : 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. LÄS MER
