  1. 1. Atmospheric & Oceanic Applications of Eulerian and Lagrangian Transport Modelling

    Författare :Joakim Kjellsson; Kristofer Döös; Jonas Nycander; Joseph LaCasce; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Eulerian; Lagrangian; trajectory; climate; atmosphere; ocean; modelling; drifter; thermodynamic; climate change; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : This thesis presents several ways to understand transports of air and water masses in the atmosphere and ocean, and the transports of energy that they imply. It presents work using various kinds of observations as well as computer simulations of the atmosphere and oceans. LÄS MER

  2. 2. Ultracold atoms in optical potentials : from noise-induced transport to superfluidity

    Författare :Martin Zelan; Claude Dion; Sile Nic Chormaic; Umeå universitet; []
    Nyckelord :Brownian motors; noise-induced transport; superfluidity; ultracold atoms; optical potentials; optical lattices; laser coooling; fysik; Physics;

    Sammanfattning : In this thesis, both experimental studies and numerical simulations of ultracold atoms in optical potentials are presented in a collection of nine scientific papers. In particular, noise-induced transport in dissipative optical lattices and superfluid properties of Bose-Einstein condensates have been studied. LÄS MER

  3. 3. Upplysning utan förnuft : begär och frihet hos Thomas Hobbes, John Locke, David Hume och Montesquieu

    Författare :Victoria Höög; Avdelningen för idé- och lärdomshistoria; []
    Nyckelord :HUMANIORA; HUMANITIES; John Locke; Thomas Hobbes; postmodernism; modernity; women; political freedom; classical republicanism; human nature; reason; virtue; passions; Enlightenment; desire; David Hume; Charles de Montesquieu.; History of philosophy; history of ideas; Filosofins historia; idéhistoria;

    Sammanfattning : This essay has three main aims. The first one is to give an overview of some hundred years of European intellectual history, bringing out new aspects of the classical thinkers. The analysis of the four philosophers Thomas Hobbes, John Locke, David Hume and Charles de Montesquieu aims at illustrating a general historical process, viz. LÄS MER

  4. 4. Regulation of antimicrobial peptide gene expression in Drosophila melanogaster : Involvement of POU and NF-kB/Rel factors in innate immunity

    Författare :Anna Junell; Ylva Engström; Jean-Luc Imler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The fruit fly, Drosophila melanogaster, has a well-developed immune response, and microbial assault induces a rapid production of potent antimicrobial peptides (AMPs). The aim of this thesis work was to gain deeper knowledge of the regulation of AMPs in Drosophila, by the isolation and characterization of transcription factors involved in AMP gene expression.

  5. 5. Signaling and transcriptional regulation of antimicrobial peptide genes in Drosophila melanogaster

    Författare :Hanna Uvell; Ylva Engström; Won-Jae Lee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antimicrobial peptides; drosophila; immunity; transcriptiona regulation; Molecular biology; Molekylärbiologi;

    Sammanfattning : Insects rely solely on innate immune reactions for protection against infect-ing microbes in their environment. In Drosophila, one major defense mechanism is the production of a battery of antimicrobial peptides (AMPs). LÄS MER
