    Författare :Gunnar Blomé; Hans Lind; Erik Högberg; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business and economics; Ekonomi;

    Sammanfattning : The purpose of the study is to increase knowledge of how to provide service in municipal housing companies in Sweden, and of various organisational models for the customer-centric organisation. The principal issue of the study is how housing companies can organise their resources in order to create an efficient and customer-centric organisation. LÄS MER

  3. 7. Deracemization of Functionalized Alcohols via Combined Ruthenium and Enzyme Catalysis

    Författare :Ann-Britt L. Fransson; Jan-Erling Bäckvall; Hans-Erik Högberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : The major part of this thesis describes the synthesis of enantiopure alcohols and diols by combining ruthenium-catalyzed racemization or epimerization and lipase-catalyzed asymmetric transformations. A minor part of this thesis is focused on ruthenium-catalyzed redox reactions for transfer hydrogenation of 1,3-cycloalkanediketones. LÄS MER

  4. 8. Enzymes as catalysts in synthesis of enantiomerically pure building blocks : secondary alcohols bearing two vicinal stereocenters

    Författare :Rong Liu; Hans-Erik Högberg; Torbjörn Norin; Thorleif Anthonsen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzyme; kinetic resolution; enantioselectivity; lipase; diastereoselectivity; epimerisation; metal-catalysed transformation; intramolecular alkylation.; Chemistry; Kemi;

    Sammanfattning : Enzymes as tools in organic synthesis have provided enormous advantages. This thesis deals with the applications of enzymes in the kinetic resolutions of racemic compounds. The stereochemistry of chiral compounds and the kinetics of α/β hydrolase lipases are presented. LÄS MER

  5. 9. Fourier Transform Infrared Spectroscopy in Industrial Hygiene Applications : Assessment of Emissions from and Exposures in Wood Processing Industries

    Författare :Urban Svedberg; Christer Edling; Bo Galle; Hans-Erik Högberg; Nils Plato; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; FTIR; Exposure; Emission; Saw mills; Wood pellets; Tracer gas; Monoterpenes; Hexanal; Carbon monoxide; Open path FTIR; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : This thesis evaluates the use of Fourier Transform Infrared Spectroscopy (FTIR) as an approach to the increasingly difficult air sampling challenges within the field of occupational and environmental hygiene. The application of FTIR is exemplified by the assessment of emissions from and exposures in the sawmill and pellet industries. LÄS MER

  7. 10. Byggherrens kostnadsstyrning : en metodstudie

    Författare :Lars Sjögren; Handelshögskolan i Stockholm; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Under det skede då ett byggprojekts utformning bestäms produktbestämningsskedet fattas huvuddelen av de beslut som avgör objektets kostnader och kvaliteter. Kostnadsstyrning har föreslagits för att styra denna planeringsprocess, som oftast sker i en samverkan mellan byggherren och ett antal projektörer. LÄS MER
