  2. 1. On Turbulent Wall Jets

    Author : Hans Abrahamsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; self-preservation; similarity theory; scaling laws; local flow reversals; high turbulence levels; turbulent kinetic energy budget; two-dimensional; turbulent; hot-wire anemometry; wall jet; three-dimensional; pulsed hot-wire anemometry;

    Abstract : An experimental investigation of the two- and three-dimensional turbulent wall jets has been conducted. The measurements have been performed using different hot-wire techniques in large scale wall jet facilities, and the measurements were focused on the fully-developed region of the flow. READ MORE

  5. 3. Kinetic Energy Storage and Magnetic Bearings : for Vehicular Applications

    Author : Johan Abrahamsson; Hans Bernhoff; Urban Lundin; Richard Magdalena Stephan; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flywheel; magnetic bearing; energy storage; electric vehicle; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. READ MORE

  6. 4. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes

    Author : Maria Abrahamsson; Leif Hammarström; Hans-Christian Becker; Russell Schmehl; Uppsala universitet; []
    Keywords : Physical chemistry; Artificial photosynthesis; Ruthenium II ; Bistridentate complexes; Excited state lifetime; Linear donor-photosenstizer-acceptor arrays; Temperature dependence; Excited state decay; Fysikalisk kemi;

    Abstract : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. READ MORE

  7. 5. Investigation and Prediction of Small Intestinal Precipitation of Poorly Soluble Drugs : a Study Involving in silico, in vitro and in vivo Assessment

    Author : Sara Carlert; Hans Lennernäs; Bertil Abrahamsson; Patrick Augustijns; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gastrointestinal precipitation; crystallization; crystal nucleation; crystal growth; classical nucleation theory; poorly soluble drugs; drug absorption; biopharmaceutics classification system; in vitro in vivo correlations IVIVC ; in silico prediction; human intestinal fluid; dog intestinal fluid; simulated intestinal fluid; Biofarmaci; Biopharmaceutics;

    Abstract : The main objectives of the present project were to increase the understanding of small intestinal precipitation of poorly soluble pharmaceutical drugs, investigate occurrence of crystalline small intestinal precipitation and effects of precipitation on absorption. The aim was to create and evaluate methods of predicting crystalline small intestinal drug precipitation using in vivo, in vitro and in silico models. READ MORE
