  3. 2. Aromatic Allylation via Diazotization; Application in synthesis of heterocyclic compounds

    Författare :Fredrik Ek; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bengamide analogue.; parallel synthesis; trimethylsilyl azide; cycloaddition; imidazole; fused tetrazole derivatives; iodocyclization; benzazepine; tert-butyl nitrite; allylic bromide; aromatic allylation; diazotization; Organic chemistry; Organisk kemi;

    Sammanfattning : A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. LÄS MER

  4. 3. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Författare :Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer; photoplethysmography; laser Doppler flowmetry; non-invasive; tissue blood flow; reactive hyperemia; pressure-induced vasodilation; interface pressure; risk assessment;

    Sammanfattning : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

  5. 4. Att anordna styrning : tillblivelse av en mångfald av styrteknologier

    Författare :Kim Eriksson; Eva Wittbom; Fredrik Svärdsten Nymans; Maria Mårtensson; Emma Ek Österberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Management control; Management control technologies; Changing management control; Multiplicity; Assemblage; Public sector; Business Administration; företagsekonomi;

    Sammanfattning : During the last couple of decades, management control studies have taken an increased interest in the multiplicity of management controls. Broadly speaking, research has focused on the consequences of management controls. However, research has rarely examined how a multiplicity of management controls comes to exist. LÄS MER
