  1. 1. Soil-living archaea: Influence of pH, carbon and nitrogen on their abundance and activity

    University dissertation from Department of Biology, Lund University

    Author : Anna Sterngren; Lunds universitet.; Lund University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Archaea; ammonia-oxidizing archaea; soil; AOA; AOB; root exudates; gross nitrification; qPCR; pH; carbon cycle; nitrogen cycle;

    Abstract : Popular Abstract in Swedish På 70-talet upptäckte man att en grupp mikroorganismer, som man tidigare katalogiserat som bakterier, bildade en helt egen grupp. Dessa kallades ärkebakterier och fick senare namnet arkéer. READ MORE

  2. 2. Vertical III-V/High-k Nanowire MOS Capacitors and Transistors

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Jun Wu; Lunds universitet.; Lund University.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; MOS capacitor; C-V; XPS; MOVPE; InGaAs; InAs; High-k; RF; Track-and-hold circuit;

    Abstract : Popular Abstract in English Since 1947 when the first transistor was invented, electronics was transited into an unprecedented era. Different from a resistor that only has two terminals with the applied voltage and flowing current always obeying Ohm's law, a transistor has the third terminal in between, called "gate", which is made by, for metal-oxide-semiconductor field effect transistors (MOSFETs), an oxide layer sandwiched between the metal electrode and the semiconductor channel.

  3. 3. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning

    University dissertation from Faculty of Engineering, LTH at Lund University

    Author : Mattias Nilsson; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elevated temperatures; Electroviscous friction; Energy; pH; Economics; Nanofiltration; Pre-treatment; Salt; Swelling; Membrane performance; Cleaning; Temperature;

    Abstract : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. READ MORE

  4. 4. The Oxygen Evolving cycle in Photosystem II studied with EPR Spectroscopy at different pH and Temperature

    University dissertation from Biochemistry Department Lund University P.O. Box 124 SE-22100 Lund Sweden

    Abstract : Popular Abstract in Swedish Fotosyntesen är nödvändig för vårt liv på jordklotet. Fotosyntes utförs huvudsakligen av gröna växter och dessutom av vissa bakterier. READ MORE

  5. 5. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants

    University dissertation from Chalmers University of Technology

    Author : Sofia Marmon; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Persistenta organiska föreningar; Persistent organic compounds; Övrig kemi; Other chemistry; Livsmedelsvetenskap; Food science; Livsmedelsteknik; Food technology; pH; acid; alkaline; solubilization; precipitation; herring; protein; dioxins; lipids; salt solubility; gelation; transmission electron microscopy; in vitro digestion;

    Abstract : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. READ MORE
