  1. 1. Interaction of Calcium Ions with Lipid Membranes

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Baharan Ali Doosti; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Abstract : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

  2. 2. Removal of Metal Ions from Wood Chips during Acidic Leaching

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Anna Saltberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scandinavian softwood; spruce; calcium; diffusion coefficient; potassium; birch; Acidic leaching; eucalyptus; metal ions; oxalate;

    Abstract : Wood chips are the main source of intake of non-process elements at kraft pulp mills. It would be advantageous to decrease the content of these elements in the chips prior to pulping. READ MORE

    Abstract : Popular Abstract in Swedish Kroppens rörelser åstadkommes genom sammandragning av muskelvävnad som kan vara av två slag, glatt eller tvärstrimmig. Den senare sorten kan indelas i skelett och hjärtmuskulatur, vilka har mycket olika egenskaper trots den gemensamma benämningen. READ MORE

  4. 4. Inorganic ions in wood chips- Leaching prior to Kraft pulping and effect of calcium on Kraft delignification

    University dissertation from Sölvegatan 19, S223 62 Lund

    Author : Anna Saltberg; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; calcium; Scandinavian softwood; Keywords: Kraft pulping; potassium; birch; eucalyptus; aspen; acidic leaching; oxalate.;

    Abstract : Wood is the main source of Non-Process Elements (NPEs), such as, calcium, potassium, manganese and chloride in Kraft pulp mills. Due to the recirculation of cooking chemicals and water, process disturbances related to the accumulation of NPEs in the process streams are inevitable. READ MORE

  5. 5. Carbonate Ions and Gastric Cancer

    University dissertation from Lund University, Faculty of Medicine
