  1. 1. Genetic dissection of tubulogenesis in the Drosophila trachea

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Johanna Hemphälä; Stockholms universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila; trachea; transposon mutagenesis screen; fusion; Dpp; Delta; tubular dimensions; Grainyhead; Krotzkopf verkehrt; intralumenal matrix; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Sammanfattning : The formation of branched tubular organs, such as the mammalian lung kidney and vascular system, is an essential process in animal development. The Drosophila tracheal (respiratory) system provides a genetic model system to study the highly ordered process of branch outgrowth and fusion required to form continuous tubular networks. LÄS MER

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Birgitta Wäppling-Raaholt; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

    Sammanfattning : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. LÄS MER

  3. 3. Genetic and molecular regulation of epithelial tube morphogenesis

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Anna Tonning; Göteborgs universitet.; Gothenburg University.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epithelial tube morphogenesis; trachea; Drosophila; chitin; chitin synthase; apical extracellular matrix; paracellular diffusion barrier; tube expansion; septate junctions;

    Sammanfattning : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. LÄS MER

  4. 4. Nanowire Heterostructures- Growth, Characterization and Optical Physics

    Detta är en avhandling från Solid State Physics, Lund University

    Författare :Niklas Sköld; Lunds universitet.; Lund University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano; Nanowire; photoluminescence; epitaxy; quantum dot;

    Sammanfattning : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. LÄS MER

  5. 5. New Techniques for Chiral Separations

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Jeanette Olsson; Karlstads universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; analytical chemistry; chiral separation; GC; CE; CEC; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; Kemi; Chemistry;

    Sammanfattning : Gas chromatography (GC) has been utilized for the study of enantiomer resolution of the atropisomers of PCBs, o,p´-DDD and o,p´-DDT. Different substituents and concentrations of cyclodextrin, capillary dimensions and type of stationary phase films have been investigated to achieve the resolution of as many of the atropisomers on one column as possible.
