  2. 1. A Study of Propane and Propene Ammoxidation over the Mo-V-Nb-Te-Oxide System

    Author : Johan Holmberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; TEM; TPR; XPS; XRD; XANES; Chemical technology and engineering; SEM; FTIR; BET; TiO2; SiO2; Al2O3; supports; substitution; synthesis; Mo-V-Nb-Te-Ox catalysts; acrylonitrile; propene; Ammoxidation; propane; symbiosis;

    Abstract : The ammoxidation of propane is commonly regarded as being the future route for producing acrylonitrile, and the Mo-V-Nb-Te-oxide system studied here has thus far been seen as the most promising candidate for achieving this. Yields of up to 62% have been presented very elegantly in the patent literature. READ MORE

  4. 2. Expression profiling using manifold supports

    Author : Anette Hagberg; Joakim Lundeberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mRNA; expression; minimal residual disease MRD ; chronic myeloid leukemia CML ; recombinant human erythropoietin r-HuEpo ; anemia; insulin dependent diabetes mellitus IDDM ; transplantation; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Abstract : Analyses of mRNA provides a condensed view of gene structure and quantitative analysis can reveal the induction of physiological or pathological gene expression programs. This thesis describes a new method for mRNA isolation, followed by sensitive real time detection via polymerase chain reaction (PCR), in order to quantitate transcripts of interest. READ MORE

  5. 3. Cryogels as Solid Supports in Bioprocessing

    Author : Gry Jespersen; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Downstream processing; cryogel; solid support; biomacromolecules; chromatography;

    Abstract : In recent years the market for biopharmaceutical products has been increasing rapidly as a result of an increased demand for new and efficient treatments of various indications. Biopharmaceuticals are distinguished from chemical drugs by being derived from a biological origin and are hence, frequently constituting biological macromolecules. READ MORE

  6. 4. Cobalt catalyst supports for Fischer-Tropsch synthesis

    Author : Fatima Pardo-Tarifa; Lars J. Pettersson; Olga Guerrero; KTH; []
    Keywords : Silica; alumina; zirconium; cerium; mesoporous materials; nanoparticles; microemulsion; atrane route; cobalt catalyst; Fischer-Tropsch synthesis; Chemical Engineering; Kemiteknik;

    Abstract : In the Fischer-Tropsch (FT) synthesis, CO and H2 (synthesis gas) are converted into hydrocarbons that can be further upgraded to high-quality fuels and chemicals. Different carbon sources such as natural gas, coal and biomass can be used as feed-stocks for the synthesis gas. READ MORE

  7. 5. Decision Making in Preflight Operations : A study of memory supports and feedback

    Author : Kristina Enflo; Örjan Wikforss; Lena K. Mårtensson; KTH; []
    Keywords : Human Factors; Man-Machine Systems; Decision Making; Decision Support; Feedback; Commercial Aviation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The purpose of this thesis is to explore how support systems enable human control within normal flight operations. The thesis focuses on the use of memory supports during flight, such as a handheld computing device, memory strategies and checklists. The support systems are studied from the theoretical perspective of Human Factors. READ MORE
