  2. 1. Modelling of Drug Release from Reservoir and Matrix Formulations - Multiple Unit Dosage Forms and Swelling and Dissolving Matrix Systems

    Author : Per Borgquist; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; XEDS; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Polymer technology; biopolymers; Polymerteknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik; simulation; single pellet; single-unit release; SEM; reservoir system; poly ethylene oxide ; film-coated; matrix; mathematical model; diffusion; pellet shape; controlled release; polymer dissolution; modelling; ethyl cellulose; Coating; multiple-unit release;

    Abstract : In this work, mathematical models have been developed describing drug release from film-coated reservoir systems as well as drug release and polymer dissolution from swelling and dissolving polymer tablets. The model derivation of both systems is based on a mechanistic approach. The model describing drug release from reservoir systems, i.e. READ MORE

  4. 2. Effects of Watershed Dynamics on Water Reservoir Operation Planning : Considering the Dynamic Effects of Streamflow in Hydropower Operation

    Author : Nicholas Zmijewski; Anders Wörman; Andrea Bottacin-Busolin; Francesca Pianosi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir operation; dispersion processes; wave diffusion; multi-objective operation; water resource management; discharge variability; power spectrum analysis; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Water reservoirs are used to regulate river discharge for a variety of reasons, such as flood mitigation, water availability for irrigation, municipal consumption and power production purposes. Recent efforts to increase the amount of renewable power production have seen an increase in intermittent climate-variable power production due to wind and solar power production. READ MORE

  5. 3. Evolution of a silicic magma reservoir in the upper crust : Reyðarártindur pluton, Southeast Iceland

    Author : Emma Rhodes; Steffi Burchardt; Abigail Barker; Charles F. Parker; Alexander Cruden; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magma; magma emplacement; magma reservoir; floor subsidence; piecemeal subsidence; granite; pluton; cap-rock; magma mingling; magma plumbing systems; volcanic and igneous plumbing systems; eruption; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : Field observations of extinct and exposed magma reservoirs shed light on processes operating in the roots of presently active volcanoes. The Reyðarártindur pluton, Southeast Iceland is an example of a fossil shallow magma reservoir that fed eruptions. READ MORE

  6. 4. Siltation and sedimentation problem in Mosul reservoir dam

    Author : Issa E. Issa; Ian Foster; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Iraq depends on the Rivers Tigris and Euphrates for its water resources. Recently the flow of these rivers decreased drastically. In view of this situation the true storage capacity of the dams are to be evaluated to ensure prudent water resources management strategies. READ MORE

  7. 5. A Fully Integrated Microneedle-based Transdermal Drug Delivery System

    Author : Niclas Roxhed; Göran Stemme; Mark G. Allen; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microneedle; Transdermal; Intradermal; Drug delivery; DRIE; MEMS; Microsystem; Medical technology; Medicinsk teknik;

    Abstract : Patch-based transdermal drug delivery offers a convenient way to administer drugs without the drawbacks of standard hypodermic injections relating to issues such as patient acceptability and injection safety. However, conventional transdermal drug delivery is limited to therapeutics where the drug can diffuse across the skin barrier. READ MORE
