  1. 1. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees

    Författare :Joakim Bång; Erik Hedenström; Kristina Sjödin; Hans-Erik Högberg; Anna-Karin Borg-Karlsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiochemicals; sex pheromone; pine sawflies; Bicyclus; Euglossa; chiral separation; derivatisation; GC-­MS; Organic chemistry; Organisk kemi;

    Sammanfattning : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). LÄS MER

  3. 2. Ett europeiserat arbetstagarinflytande : en rättslig studie av inflytandedirektivens genomförande i Sverige

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; labour law; employee involvement; EU labour law; MBL; medbestämmande; mbl11; mbl19; LSA; 2001 23; 98 59; 2002 14 EWC; Europeiska företagsråd; arbetstagares styrelserepresentation; arbetsrätt; arbetstagarinflytande; EU-arbetsrätt; Civil Law; Civilrätt;

    Sammanfattning : Employee involvement is a central question in labour law. In this dissertation the author examines eight EU directives (the involvement directives) with provisions on employee involvement. The aim of the dissertation is to analyse the content of the involvement directives and how they have affected the Swedish system of employee involvement. LÄS MER

  4. 3. Strength and Moisture Aspects of Steel Timber Dowel Joints in Glulam Structures : An Experimental and Numerical Study

    Författare :Johan Sjödin; Erik Serrano; Per Johan Gustafsson; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; glu-lam beams; glulam structures; linear elastic fracture mechanics; moisture-induced stresses; numerical simulations; short term capacity.; Building engineering; Byggnadsteknik;

    Sammanfattning : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of e.g. a building depends strongly on the structural configuration and the capacity of its joints. LÄS MER

  5. 4. Resonant multi-photon ionisation studies of high-energy states in small molecules

    Författare :Marica Sjödin; Lars-Erik Berg; Arne Rosén; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This thesis describes separate studies of high-energy Rydberg and ion-pair states in small molecules using resonant multi-photon ionisation spectroscopy. * OODR/REMPI study of ungerade Rydberg states in O2 The energy region between 75000 and 99900 cm-1 of O2 has been studied using optical-optical double resonance (OODR) with resonance enhanced multi-photon ionisation (REMPI).
