  1. 6. Side-chain oxidized oxysterols as metabolic regulators in vivo

    Författare :Zeina M F Ali; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxysterols are oxygenated derivatives of cholesterol characterized by a very short half- life and their ability to pass lipophilic membranes easily, and they are considered as important intermediates in the excretion pathways of cholesterol and its conversion to bile acids. Evidence has been presented that the production and flux of oxysterols in the brain may also be of some importance for cognitive functions. LÄS MER

  3. 7. Innate and adaptive immunity in genital HSV-2 infection: Implications for vaccine development

    Författare :Ali M Harandi; Göteborgs universitet; []
    Nyckelord :genital herpes infection; natural antibody; CD4 T cells; CD8 T cells; IFN-g; IL-12; IL-18; CC chemokines; dendritic cells.;

    Sammanfattning : Herpes simplex virus type 2 (HSV-2) is a sexually transmitted pathogen that infects the genital tract mucosa and is the most common case of genital ulcers in humans. Despite numerous studies, little is known about the mechanisms involved in immune protection and no anti-herpes vaccine has been developed to date. LÄS MER

  4. 8. Morphology of Tigris River inside Baghdad City

    Författare :Ammar Adel Ali; Govand H. M. Sherwani; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Tigris and Euphrates rivers represent the artery of life in Iraq. Tigris River rises from Turkey and flows toward the southeast to enter Iraq. It drains a catchment area of 473 100 km² of which about 58% lies in Iraq. In this study the reach, about 50 km long, of the river inside Baghdad was been studied. LÄS MER

  5. 9. Polyelectrolytes : Bottle-Brush Architectures and Association with Surfactants

    Författare :Ali Naderi; Per M. Claesson; Orlando Rojas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte; Surfactant; Bottle-Brush Polyelectrolyte; Comb Polyelectrolyte; Non-Equilibrium State; Polymer Architecture; Adsorption; Desorption; Association; Excluded Volume; Light Scattering; SFA; AFM; QCM-D; Turbidimeter; Mica; Silica; Surface Forces; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis has the dual purpose of raising awareness of the importance of the mixing protocol on the end products of polyelectrolyte-oppositely charged surfactant systems, and to contribute to a better understanding of the properties of bottle-brush polyelectrolytes when adsorbed onto interfaces. In the first part of this thesis work, the effects of the mixing protocol and the mixing procedure on formed polyelectrolyte-oppositely charged surfactant aggregates were investigated. LÄS MER

  7. 10. Integrated Photonics for Quantum Optics

    Författare :Samuel Gyger; Val Zwiller; Stephan Steinhauer; Ali W. Elshaari; Marijn A. M. Versteegh; Matthew D. Shaw; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integrated photonics; single-photons; single-photon sources; quantum dots; single-photon detectors; SNSPD; integrerad fotonik; enstaka fotoner; enstaka fotonkällor; kvantprickar; enstaka fotondetektorer; SNSPDs; Optics and Photonics; Optik och fotonik; Physics; Fysik;

    Sammanfattning : Quantum physics allows us a vision of Nature's forces that bind the world, all its seeds and sources. After decades of primarily scientific research, we've arrived at a stage in time where quantum technology can be applied to practical problems and add value outside the field. LÄS MER
