  1. 21. Improving Procurement Performance with E-business Mechanisms

    Författare :Daniel Knudsen; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell ekonomi; Commercial and industrial economics; e-procurement; e-business; procurement; purchasing;

    Sammanfattning : E-procurement — e-business mechanisms deployed on procurement — offers many recent and innovative methods that can improve procurement in different ways. The key challenge of e-procurement, however, is how to apply the various e-procurement applications in such a way that they improve the procurement practice and sourcing strategy of a company.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; B3LYP; enzyme; cluster approach; mechanism; zinc; manganese; cytosine deaminase; ω-transaminase; dinitrogenase reductase-activating glycohydrolase; dual substrate recognition; organisk kemi; Organic Chemistry;

    Sammanfattning : Computer modeling of enzymes is a valuable complement to experiments. Quantum chemical studies of enzymatic reactions can provide a detailed description of the reaction mechanism and elucidate the roles of various residues in the active site. LÄS MER

  4. 23. Risk-Averse Planning, Operation, and Coordination of Energy Systems Considering Uncertainty Modeling and Flexibility Services

    Författare :Hamed Bakhtiari; Jin Zhong; Manuel Alvarez; Jalal Kazempour; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system planning and operation; energy systems coordination; uncertainty modeling; microgrids; renewable energy; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : Uncertainty sources affect the planning and operation of energy systems. Different system operators need proper alternatives to cope with these uncertainties and improve the operation of their systems from technical and economical viewpoints. LÄS MER

  5. 24. Coordination of endocytosis at the synaptic periactive zone

    Författare :Emma Evergren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Synapse; endocytosis; clathrin; dynamin; amphiphysin; synapsin; intersectin; actin cytoskeleton; immunogold electron microscopy.;

    Sammanfattning : Neurons in the central nervous system communicate via specialized junctions called synapses. Neurotransmitter-filled vesicles are clustered at these junctions, where they are released in response to synaptic activity. To sustain reliable neurotransmission the synaptic vesicles are recycled locally. LÄS MER

  7. 25. Understanding the mechanisms behind atom transfer radical polymerization : exploring the limit of control

    Författare :Helena Bergenudd; Mats Jonsson; Eva Malmström Jonsson; David M Haddleton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymerization; controlled radical polymerization; atom transfer radical polymerization; kinetics; catalysis; electrochemistry; Polymer chemistry; Polymerkemi;

    Sammanfattning : Atom transfer radical polymerization (ATRP) is one of the most commonly employed techniques for controlled radical polymerization. ATRP has great potential for the development of new materials due to the ability to control molecular weight and polymer architecture. LÄS MER
