  1. 1. Azimuthal Correlations in Dijet Events from Deep Inelastic Positron-Proton Scattering at HERA

    Author : Magnus Hansson; Partikelfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Jets; Azimuthal Correlations; Dijets; Parton Dynamics; Low-x; H1; HERA; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2007:Hansson;

    Abstract : Correlations in the azimuthal angle between dijets produced in deep inelastic $e^{+}p$ scattering events, collected by the H1 experiment during 1999-2000, have been investigated. Cross sections are presented as a function of the azimuthal separation between the two jets in the hadronic center of mass frame, $Deltaphi^{*}$, in different regions of the photon virtuality $Q^{2}$ and in different regions of the Bjorken scaling variable $x_{Bj}$.

  2. 2. From dusk till dawn : three essays on organizational closedowns

    Author : Magnus Hansson; Rune Wigblad; Örebro universitet; []

    Abstract : This thesis present three essays on organizational closedowns, where productivity effects under uncertainty and threat on the single-firm level is in focus. On a broad level, this thesis aims to develop better explanations of the process of organizational closedowns. READ MORE

  3. 3. Mitochondrial permeability transition following calcium overload. - Its role in neuronal cell death and potential as a pharmacological target

    Author : Magnus Hansson; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; farmakognosi; farmaci; Bioenergetik; Bioenergetics; neuropsykologi; toxikologi; neurofysiologi; Neurologi; Neurology; neurophysiology; neuropsychology; Neurodegeneration; Mitochondria; Brain; Pharmacological sciences; pharmacognosy; pharmacy; Farmakologi; toxicology;

    Abstract : There is currently no clinically available drug with neuroprotective properties to limit the evolving cell death following e.g. stroke or traumatic brain injury. The mitochondrial permeability transition (mPT) is a potential pathological mechanism causing cell death in the CNS. READ MORE

  4. 4. Studies on human sterol 27-hydroxylase with emphasis on its mechanism of regulation and metabolic consequences of a deficient enzyme

    Author : Magnus Hansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sterol 27-hydroxylase (CYP27A1) is a mitochondrial cytochrome P-450 enzyme present in most animal cells. In hepatocytes, CYP27A1 has an important role in connection with biosynthesis of bile acids from cholesterol. READ MORE

  5. 5. Molecular mechanisms of the transcriptional co-activator mastermind-like 1

    Author : Magnus L Hansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Gene regulation is a complex process that requires several types of proteins, including chromatin-modifying enzymes, transcription factors, co-activators and co-repressors. We have investigated the molecular mechanisms underlying the action of the co-activator protein MAML1, which was first identified as a transcriptional co-activator for Notch receptors. READ MORE
