  2. 11. Numerical modeling of groundwater and air flow between compacted bentonite and fractured crystalline rock

    Author : Benoît Dessirier; Jerker Jarsjö; Andrew Frampton; Stefan Finsterle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-phase flow; porous media; fractured media; compacted bentonite; crystalline rock; numerical modeling; geological disposal; Physical Geography; naturgeografi;

    Abstract : The geological repository for final storage of spent nuclear fuel, envisioned by the Swedish Nuclear Fuel and Management Company (SKB), relies on several barriers: copper canisters deposited in holes in the floor of underground tunnels in deep bedrock, embedded in a buffer of compacted bentonite. The initially unsaturated buffer would take up water from the surrounding rock mass and swell to seal any potential gap. READ MORE

  4. 12. 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

  5. 13. Mechanical Pulp-Based Nanocellulose : Processing and applications relating to paper and paperboard, composite films, and foams

    Author : Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Mark Martinez; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose; microfibrillated cellulose; nanofibrillated cellulose; paper; strength properties; crill; TEMPO; nanographite NG ; composite films;

    Abstract : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.

  6. 14. Towards understanding breakage and flow in sublevel caving (SLC) : Development of new measurement techniques and results from full-scale tests

    Author : Matthias Wimmer; Pekka Särkkä; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. READ MORE
