    Sammanfattning : Transmission of structure-borne vibrations in built-up structures, e.g. vehicles such as aircraft, automobiles and trains, is addressed. Methodologies for modeling, analysis, prediction and reduction of vibrations are developed. LÄS MER

  4. 3. Colon cancer : management and outcome in a Swedish population

    Författare :Annika Sjövall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Colonic carcinoma; Population-based study; loco-regional recurrence; hepatic metastasis; survival;

    Sammanfattning : Colon cancer is common in Sweden, with about 3500 new cases every year. Tumours of the colon and rectum are usually addressed as an entity. Great effort has been made to improve the outcome after rectal cancer treatment with subsequent improvement of survival. LÄS MER

  5. 4. Structural aspecs on compounds in the CsI-(Cd/Hg)I2 system

    Författare :Rune Sjövall; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tetrahedral distorsion; thermal decomposition; Biltz concept; structural relationships; hydrate; iodine; mercury; caesium; cadmium; coordination number modelling; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Structural investigations of compounds in the CsI-(Cd/Hg)I2 system have been performed by means of X-ray diffraction, thermogravimetric and calorimetric techniques. Crystals of the compounds studied were synthesized from aqueous solutions of CsI and CdI2/HgI2 by the slow evaporation of water. LÄS MER

  7. 5. Metallacyclic Phosphine Complexes and Intramolecular Csp3-H Bond Activation -Synthesis, Characterisation and Catalytic Application

    Författare :Sven Sjövall; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; Heck; diphosphite; diphosphine; phosphine; cyclometallation; C-C activation; C-O activation; C-H activation; palladium; rhodium; iridium; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : The work presented in this thesis deals with metallacyclic late transition metal complexes, obtained by intramolecular Csp3-H activation, and the application of such compounds in catalysis. The new hemilabile P,O phosphines N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine (DPPAM), o-(diphenylphosphino)benzoic acid ethyl ester (DPPES), o-(diphenylphosphino)benzoic acid methyl ether (DPPET) and ±-1-(2- diphenylphosphino)phenylethyl propionate (±-DPPMES) and the symmetrical diphosphorus donor ligands cis-1,3-bis[(diphenylphosphino)methyl]-cyclohexane (DPCY), cis-1,3-bis[(di-tertbutylphosphino)methyl]cyclohexane (DTBCY) and cis-1,3-bis[(di-isopropylphosphino)methyl]cyclohexane (DIPCY) have been synthesised, allowing the preparation of a range of new metallacyclic rhodium(III), iridium(III) and palladium(II) complexes.
