    Abstract : CdS is conventionally used as a buffer layer in Cu(In,Ga)Se2, CIGS, solar cells. The aim of this thesis is to substitute CdS with cadmium-free, more transparent and environmentally benign alternative buffer layers and to analyze how the material properties of alternative layers affect the solar cell performance.

    Abstract : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasively colonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. READ MORE

  5. 3. Pathogenesis and Cell Biology of the Salmon Parasite Spironucleus salmonicida

    Author : Ásgeir Ástvaldsson; Staffan Svärd; Jon Jerlström-Hultqvist; Scott Dawson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diplomonads; Spironucleus; Giardia; genome; annexin; oxygen stress; APEX; pathology;

    Abstract : Spironucleus species are classified as diplomonad organisms, diverse eukaryotic flagellates found in oxygen-deprived environments. Members of Spironucleus are parasitic and can infect a variety of hosts, such as mice and birds, while the majority are found to infect fish. READ MORE

  6. 4. Design, expression, and analysis of antibody-based blood-brain barrier shuttles

    Author : Andrés de la Rosa; Greta Hultqvist; Paul O'Callaghan; Nicole G. Metzendorf; Torben Moos; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibody therapeutics; transient gene expression; protein production; blood-brain barri-er BBB ; BBB shuttle; brain delivery; Transferrin receptor TfR ; heparan sulfate; holo-transferrin; Molekylär biovetenskap; Molecular Life Sciences;

    Abstract : Antibody therapeutics, with their strong and highly selective target binding, are now used to treat various diseases. However, to enable their use to treat brain disorders, they must be delivered across the blood-brain barrier (BBB), as without active transport, only around 0.01% of intravenously injected doses reach the brain.

  7. 5. Search for Neutrinos from Gamma-ray Bursts using the IceCube Neutrino Observatory

    Author : Kunal Avinash Deoskar; Chad Finley; Klas Hultqvist; Paschal Coyle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gamma-ray bursts; neutrinos; IceCube Neutrino Observatory; Physics; fysik;

    Abstract : Gamma ray bursts (GRBs) are short bursts of high energy γ-radiation and are among some of the most energetic phenomena in the universe. GRBs have three distinct emission phases: the prompt phase with high-energy γ-rays, the precursor phase which is the time interval before the prompt phase and is reported to have an additional smaller burst for some GRBs, and the afterglow phase which is the time interval after the prompt phase with observations for electromagnetic radiation across a large wavelength range reported for many GRBs.
