  1. 1. Draw control strategy for sublevel caving mines : A holistic approach

    Författare :Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Laeeque Daneshmend; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control strategy; sublevel caving SLC ; loading process; draw point; caving operation; Bayesian statistics; probability models; economic models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER

  4. 3. Padlock Probe-Based Nucleic Acid Amplification Tests : Point-of-care Diagnostics of Infectious Diseases

    Författare :Sibel Ciftci; Mats Nilsson; Jonas Klingström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleic Acid Amplification; Isothermal Amplification Methods; Padlock Probes; Rolling Circle Amplification; Molecular Diagnostics; Infectious Disease Diagnostics; Virus; Point-of-Care; Biochemistry; biokemi;

    Sammanfattning : Recent advancements in molecular biology and biotechnology have pushed the field of molecular diagnostics much further to benefit the society towards smart access for rapid and simplified health care. In this context, point-of-care (PoC) technologies that bring the inventions in diagnostics closer to bedside settings draw attention. LÄS MER

  5. 4. Barns teckningar som utgångspunkt i det naturvetenskapliga samtalet

    Författare :Johanna Andersson; Lena Tibell; Jesper Haglund; Christina Ottander; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; children; drawings; conceptions; heat; mixning; human body; living min-living; barn; teckningar; föreställningar; värme; blandning; människokroppen; levande inte levande;

    Sammanfattning : Barns föreställningar utgör en viktig del i deras begreppsbildning inom naturvetenskap vilket betonas inom konstruktivismen. I denna avhandling utgör en socialkonstruktivistisk syn på lärande det teoretiska ramverket. LÄS MER

  7. 5. Microfluidics in Surface Modified PDMS : Towards Miniaturized Diagnostic Tools

    Författare :Sara Thorslund; Fredrik Nikolajeff; Jonas Bergquist; Elisabeth Verpoorte; Uppsala universitet; []
    Nyckelord :Materials science; µTAS; micro total analysis system; PDMS; poly dimethylsiloxane ; microfluidics; heparin; blood filtration; on-chip; ESI-MS; desalting; QCM-D; biocompatible; CD4; capillary flow; lab-on-chip; microfabrication; enrichment; point-of-care; hydrophilic; oxidation; Materialvetenskap;

    Sammanfattning : There is a strong trend in fabricating miniaturized total analytical systems, µTAS, for various biochemical and cell biology applications. These miniaturized systems could e.g. gain better separation performances, be faster, consume less expensive reagents and be used for studies that are difficult to access in the macro world. LÄS MER
