1. 1. Theoretical studies of chemical dynamics on excited states, driven by non-adiabatic effects : Charge recombination reactions

   Författare :Sifiso Musa Nkambule; Åsa Larson; Adam Kirrander; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mutual neutralization; Dissociative recombination; electronic structure; non-adiabatic; teoretisk fysik; Theoretical Physics;

   Sammanfattning : This thesis is based on theoretical studies of molecular collisions occurring at relatively low to intermediate collision energies. The collisions are called dissociative recombination (DR) and mutual neutralization (MN). LÄS MER

3. 2. Molecular Hole Punching : Impulse Driven Reactions in Molecules and Molecular Clusters

   Författare :Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Joachim Burgdörfer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAHs; Fullernes; Reactions; Clusters; Interstellar Medium; Fragmentation; Non-Statistical Fragmentation; Collisions; Experiments; Molecular Dynamics; Density Functional Theory; fysik; Physics;

   Sammanfattning : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. LÄS MER

4. 3. Immune defense reactions in freshwater crayfish : Cellular components

   Författare :Charlotta Ekblom; Irene Söderhäll; Kallaya Sritunyalucksana-Dangtip; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; crustaceans; hemocytes; immunity; crayfish; proteomics; transcriptomics; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

   Sammanfattning : The freshwater signal crayfish, Pacifastacus leniusculus, is a well-established model for studying the immune system of invertebrates. Many important discoveries have been made in this species, among others related to the clotting reaction, hematopoiesis, the prophenoloxidase activating system, the functions of crustacean immune cells, and pathogen recognition.

5. 4. Borderline psychopathology and the defense mechanism test

   Författare :Elisabet Sundbom; Bengt-Åke Armelius; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Defense Mechanism Test; defense mechanisms; percept-genetics; Structural Interview; Borderline Personality Organization; Borderline Personality Disorder; Principal Component Analysis; PLS-discriminant analysis;

   Sammanfattning : The main purpose of the present studies has been to develop the Defense Mechanism Test (DM1) for clinical assessment of severe psychopathology with the focus on the concept of Borderline Personality Organization (BPO) according to Kemberg. By relating the DMT and the Structural Interview to each other, the concurrent validity of the concept of Personality Organization (PO) for psychiatric inpatients has been investigated. LÄS MER

7. 5. Catalytic reactions with palladium supported on mesocellular foam : Applications in hydrogenation, isomerization, and C-C bond forming reactions

   Författare :Anuja Nagendiran; Jan-Erling Bäckvall; Shu Kobayashi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesocellular foam; Heterogeneous palladium catalysis; nanopalladium; organisk kemi; Organic Chemistry;

   Sammanfattning : The major part of this thesis concerns the development of catalytic methodologies based on palladium nanoparticles immobilized on aminopropyl-functionalized siliceous mesocellular foam (Pd0-AmP-MCF). The catalytic activity of the precursor to the nanocatalyst, PdII-AmP-MCF is also covered by this work. LÄS MER
