  2. 1. Alpha-1-microglobulin: Innate defence against pathological oxidation

    Author : Magnus Gram; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-1-microglobulin; pathological oxidation; hemoglobin; heme; radiation; oxidation; ROS; hemoglobin and heme antagonist; radical scavenger;

    Abstract : Oxidative stress has been implicated as an important factor in the progression of many diseases. An imbalance in the redox-system may cause oxidation of cells and molecules, which might subsequently lead to tissue damage. READ MORE

  4. 2. Microstructure and Mechanical Properties of Plasma Atomized Refractory Alloys

    Author : Marina Ciurans Oset; Farid Akhtar; Johanne Mouzon; Dariusz Jarzabek; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma atomization; spherical powder; tungsten carbide; high entropy alloy; refractory; Engineering Materials; Materialteknik;

    Abstract : Plasma centrifugal atomization is a method widely used in the production of spherical powders of metals and alloys with relatively low melting points. A novel plasma centrifugal atomization process suitable for high melting point materials (i.e. 3500 ᵒC and above) was developed by Metasphere Technology AB, currently Höganäs Sweden AB. READ MORE

  5. 3. Preparation and Characterization of Glow Disharge Modifies Titanium Surfaces

    Author : Björn-Owe Aronsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium; surface modification; surface properties; plasma techniques; oxidation; surface spectroscopy; TiO2; biomaterials;

    Abstract : The main theme of the present thesis is controlled preparation and characterization of oxidized titanium surfaces. Such surfaces are of general technological interest. READ MORE

  6. 4. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging

    Author : Arashk Memarpour; Pär Jönsson; Torbjörn Carlberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Post- Mortem; industrial preheating; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Yttria Stabilized Zirconia; plasma spray-PVD coating;

    Abstract : The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. READ MORE

  7. 5. Prevention of hemolysis as a novel strategy to limit hemoglobin-mediated lipid oxidation in fish - towards a more sustainable use of fish raw materials

    Author : Semhar Ghirmai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hemoglobin; herring Clupea harengus ; fish; rainbow trout Oncorhynchus mykiss ; erythrocyte; hemolysis; side-stream; antioxidant; lipid oxidation; blood plasma;

    Abstract : Hemoglobin (Hb) has been recognized as a main pro-oxidant in fish, causing fast and intense lipid oxidation. This thesis explores the hypothesis that maintaining red blood cells (RBCs) intact for an extended time during fish processing could delay Hb-mediated lipid oxidation. READ MORE
