  1. 1. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis Studies on Zone Broadening and Analytical Performances

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sheila Mohabbati; Douglas Westerlund; Bo Karlberg; [2006]
    Keywords : Pharmaceutical chemistry; Capillary electrophoresis; capillary coatings; proteins; zone broadening; zone sharpening; efficiency; resolution; protein-surface adsorption; protein-buffer interaction; analytical performance; Farmaceutisk kemi;

    Abstract : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. READ MORE

  2. 2. The zone concept design of low-voltage installations considering the spread of high frequency harmonics

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Martin Lundmark; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

    Abstract : The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy.

  3. 3. Hybrid zone dynamics, assortative mating, and migratory programmes in a willow warbler migratory divide

    University dissertation from Department of Biology, Lund University

    Author : Keith Larson; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; migratory divide; phenotype; willow warbler; hybrid zone; tension zone; Phylloscopus trochilus; migratype; assortative mating; migration;

    Abstract : In this thesis I will compare and contrast the two willow warbler subspecies (Phylloscopus trochilus trochilus and P. t. acredula) with differing migratory phenotypes (or "migratype") in the context of their migratory divide and hybrid zone in central Sweden. Their migratory programs differ in the direction and distance traveled during migration. READ MORE

  5. 5. Transformation of Micropollutants in the Hyporheic Zone

    University dissertation from Stockholm : Department of Environmental Science, Stockholm University

    Author : Malte Posselt; Jonathan P. Benskin; Michael Radke; Merle Plassmann; Magnus Breitholtz; Ian Cousins; Gudrun Massmann; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; micropollutants; hyporheic zone; biodegradation; bacteria; pharmaceuticals; transformation products; LC-MS MS; macrophytes; bedforms; suspect screening; mesocosm; flume; river; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Hyporheic zones (HZs) are reactive transition regions between rivers and aquifers which are thought to play an important role in the attenuation of micropollutants. Micropollutants are chemical substances such as pharmaceuticals, industrial chemicals or personal care products that are found in trace concentrations in the environment and that can be harmful to organisms.
