1. 1. Validity and reliability of vehicle collis : crash pulse recorders for impact severity and injury risk assessment in real-life frontal impacts

   Författare :Anders Kullgren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :crash recorder; crash pulse recorder; impact severity; injury risk; real-life impacts; measurement accuracy; neck injuries; long-term consequences; reconstruction;

   Sammanfattning : The general objectives of this thesis were to study the importance of valid and reliable data from real- life collisions, especially the effects of inaccurate data on analyses of eg injury risks. Furthermore an objective was to develop and validate an on-board measurement device for acceleration measurements, to be used in reconstructions of primarily frontal impacts. LÄS MER

3. 2. Linear models for multiscale materials simulations : Towards a seamless linking of electronic and atomistic models for complex metal oxides

   Författare :Akshay Krishna Ammothum Kandy; Peter Broqvist; Jolla Kullgren; Eddie Wadbro; Ben Hourahine; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Force fields; Electronic structure calculations; CCS; DFTB; CCS Q; repulsive fitting; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : Multiscale modelling approaches, connecting data from electronic structure calculations all the way towards engineering continuum models, have become an important ingredient in modern materials science. Materials modelling in a broader sense is already amply used to address complex chemical problems in academic science, but also in many industrial sectors. LÄS MER

4. 3. Clinical studies on the borderline concept with special reference to suicidal behavior

   Författare :Gunnar Kullgren; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; borderline;

   Sammanfattning : The diagnostic concept of borderline personality has had various meanings throughout the last decades. From current clinical practice and research two principally different concepts have emerged: The syndrome concept of borderline personality disorder ( BPD ) as identified by the DSM-III or the Diagnostic Interview for Borderline (DIB) and the psychodynamic concept of borderline personality organization (BPO) as defined from the structural Interview (SI) by Otto Kernberg.

5. 4. Oxygen Vacancy Chemistry in Ceria

   Författare :Jolla Kullgren; Kersti Hermansson; Shluger Alex; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ceria; Density Functional Theory; Oxygen storage; Nano crystals; Sulfur poisoning; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : Cerium(IV) oxide (CeO2), ceria, is an active metal oxide used in solid oxide fuel cells and for the purification of exhaust gases in vehicle emissions control. Behind these technically important applications of ceria lies one overriding feature, namely ceria's exceptional reduction-oxidation properties. LÄS MER

7. 5. Environmental, nutritional and endocrine regulation of metabolic processes in fish

   Författare :Andreas Kullgren; Göteborgs universitet; []
   Nyckelord :lipids; metabolism; temperature; fasting; growth hormone; ghrelin; NMR; metabolomics; Salmo salar; Oncorhynchus mykiss;

   Sammanfattning : Due to seasonal variations in temperature and food availability, fish in temperate regions should be able to make metabolic adjustments to ensure that enough energy is available for the maintenance of basal processes. The major aim of this thesis was to elucidate how the physiology and lipid metabolism of salmonid fish is affected by temperature and food availability, and to clarify aspects of the endocrine control of lipid metabolism.
