  1. 21. Bilder av småföretagares ekonomistyrning

    Författare :Jörgen Andersson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Utvecklingen av ekonomisk styrning och även den aktuella debatten inom området är till stora delar koncentrerad till stora företag. Under en seminarieserie om risker i samband med nyföretagande anordnad av Närings- och teknikutvecklingsverket (NUTEK) aktualiserades frågan om ekonomisk styrning i små och nystartade företag.

  3. 22. Design of Cellulose-based Materials by Supramolecular Assemblies

    Författare :Tobias Benselfelt; Lars Wågberg; Torbjörn Pettersson; Joseph Schlenoff; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; adsorption; alginate; assemblies; biodegradable; biomaterials; biopolymers; cellulose; cellulose nanofibrils; CNFs; gas barrier; hemicellulose; interfaces; ion-ion correlation; latex; layer-by-layer; metal-ligand complexes; montmorillonite; multivalent ions; packaging; PISA; polyelectrolyte multilayers; polyelectrolytes; polysaccharides; RAFT; renewable; specific ion effects; supramolecular; surfaces; sustainable; thin films; water-resilient; xyloglucan; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

  4. 23. Varför bildas nya partier? : Om kollektivt handlande och partientreprenörer

    Författare :Gissur Erlingsson; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social sciences; Swedish Municipalities; Rational Imitation; Emotions and Rationality; Entrepreneurs; Rational Choice; Methodological Individualism; Paradox of Participation; New Political Parties; Collective Action; Political and administrative sciences; Samhällsvetenskaper; Statsvetenskap; förvaltningskunskap;

    Sammanfattning : Since political parties are collective goods, groups of people that demand new political parties face a collective action problem. Therefore, we can speak of a ?paradox of party-emergence?. Hence, it is puzzling that new parties became increasingly common in representative bodies at the Swedish local level during 1973?2002.

  5. 24. Controller Work in Strategic Capital Investment Projects : Case Studies in a Swedish Mining Company

    Författare :Bo Karlsson; Anders Hersinger; Monika Kurkkio; Elin Funck; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accounting and Control; Redovisning och styrning;

    Sammanfattning : There is a tendency in the management accounting literature to emphasize systems, procedures, models and techniques, designed to improve planning, and control of business activities. This tendency is also visible in the more specific stream of literature that concerns capital investment decision making. LÄS MER

  7. 25. Surface Studies of Model Systems relevant for Pd and Ag Catalysts

    Författare :Natalia Martin; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High Pressure X-ray Photoelectron Spectroscopy; X-ray Photoelectron Spectroscopy; alumina; Ag; NiAl; Pd; catalysis; model system; Surface X-ray Diffraction; Low Energy Electron Diffraction; Scanning Tunneling Microscopy; Fysicumarkivet A:2014:Martin;

    Sammanfattning : This PhD thesis reports on investigations of the atomic scale structure of model catalysts relevant for the catalytic oxidation of CO and methane over Pd, and NOx reduction over silver-alumina, important reactions in automotive catalysts. By using complementary experimental techniques such as X-ray Photoelectron Spectroscopy, High Pressure X-ray Photoelectron Spectroscopy, Surface X-ray Diffraction, Low Energy Electron Diffraction, Infrared Spectroscopy, and Scanning Tunneling Microscopy, combined with theoretical calculations, the work presented in this thesis aims at an atomistic characterization of the active sites for silver-alumina and Pd model catalysts which may help to the design of new and improved catalysts.
