  1. 11. Bacterial Terminal Oxidases. Studies in Bacillus subtilis

    Författare :Lena Winstedt; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mycology; virology; mykologi; bakteriologi; Mikrobiologi; bacteriology; Microbiology; di-copper center; cytochrome oxidase; Enterococcus faecalis; cytochrome bd; Bacillus subtilis; terminal oxidase; virologi;

    Sammanfattning : The final step in aerobic respiratory pathways is catalyzed by terminal oxidases. Bacteria generally have two or more terminal oxidases. Aerobically grown Bacillus subtilis synthesize three terminal oxidases: one cytochrome c oxidase, cytochrome caa3 and two quinol oxidases, cytochrome aa3 and cytochrome bd. LÄS MER

  3. 12. Modeling Realized Covariance of Asset Returns

    Författare :Gustav Alfelt; Joanna Tyrcha; Taras Bodnar; Tatjana von Rosen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; matematisk statistik;

    Sammanfattning : In this thesis, which consists of two papers, we consider the modeling of positive definitive symmetric matrices, in particular covariance matrices of financial asset returns. The return covariance matrix describes the magnitude in which prices of financial assets tend to change over time, and how price changes between different assets are related. LÄS MER

  4. 13. Topics in optimal design of experiments

    Författare :Sofia Normark; Hans Nyquist; Johan Lyhagen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimal design; factorial experiments; minimax designs; efficiency; locally optimal designs; generalized linear models; binary data; statistik; Statistics;

    Sammanfattning : This thesis contributes to optimal design of experiments in situations where the optimal design depends on unknown parameters. Such situations often occur when the response variable does not have normal distribution, as is the case with many generalized linear models (GLM) and many models for binary response. LÄS MER

  5. 14. Scattering on the Timoshenko Beam. Direct and Inverse Problems in the Time Domain

    Författare :Dag V. J. Billger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integro-differential equations; wave splitting; transient wave propagation; viscoelastic damping; wave propagators; inverse problems; scattering operators; Timoshenko beam; non-uniform beams; imbedding;

    Sammanfattning : This thesis concerns the use of time domain methods for treating direct and inverse scattering problems for flexural waves on beams. The Timoshenko equation is used throughout to describe the behaviour of such waves. LÄS MER

  7. 15. Methodological studies of eicosanoid enzyme gene expression in vascular endothelium exposed to biomechanical stress

    Författare :Roya Doroudi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostanoids; endothelium; quantitative RT-PCR; perfusion model; shear stress; intraluminal pressure; immediate-early genes;

    Sammanfattning : Prostaglandins are the major eicosanoids synthesized by vascular endothelial cells, and the vasculature is an important target organ for their bioactive metabolites. In vitro studies have shown that biomechanical forces are important regulators of vascular expression of prostanoid enzymes and release of metabolites. LÄS MER
