  1. 16. Surface defects in rails - Potential influence of operational parameters on squat initiation

    Author : Robin Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RCF; squats; dynamic vehicle–track interaction; rail corrugation; Rail surface irregularities;

    Abstract : Despite significant efforts throughout the last decades, the mechanisms behind the formation of squats — a form of rolling contact fatigue (RCF) damage in rails — are not fully understood. Proposed causes of initiation involve, but are not limited to, small initial rail surface irregularities which yield high contact stresses, rail corrugation and varying friction conditions.

  2. 17. The fibrinolytic enzyme system : new markers of potential interest in cardiovascular disease

    Author : Arvid Nordenhem; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fibrinolysis; myocardial infarction; tissue plasminogen activator; PAI-1;

    Abstract : Impaired fibrinolytic function, mainly due to elevated plasma levels of PAI-1, is a common finding in patients with coronary heart disease. Determination or evaluation of the plasma PAI-1 concentrations are complicated, due to a natural variation in blood plasma or due to other reasons, such as a poor stability under physiological conditions.

  3. 18. HPV genotyping and potential progression markers in cervical intraepithelial neoplasia : clinical and diagnostic impact

    Author : Sophia Brismar Wendel; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The aim of this thesis is to identify clinically useful early molecular markers to predict progression to carcinoma in women with preinvasive lesions of the cervix, for the purpose of improving care of these women and enabling more individualized treatment. In order to define the human papillomavirus (HPV) types in minor cytological abnormalities, 343 liquid-based cytology (LBC) samples with atypical squamous cells of uncertain significance (ASCUS) and with low-grade squamous intraepithelial lesions (LSIL) were genotyped using Linear Array.

  4. 19. Flow boiling of ammonia and propane in mini channels

    Author : Muhammad Hamayun Maqbool; Björn Palm; Rahmatollah Khodabandeh; Satish Kandlikar; KTH; []
    Keywords : Flow Boiling; Mini channels; Global Warming Potential; Ammonia; Propane; R134a; HFC; Two-phase; Heat Transfer; Pressure Drop; Dry out.;

    Abstract : The environmental concerns in recent times have grown especially after signing Montreal protocol. In the last ten years, researchers have focussed mainly on understanding the boiling and condensation phenomena of HFC refrigerants in minichannels. READ MORE

  5. 20. Quantum Chemical Studies of Radical Cation Rearrangement, Radical Carbonylation, and Homolytic Substitution Reactions

    Author : Daniel Norberg; Nessima Salhi-Benachenhou; Sten Lunell; Tim Clark; Uppsala universitet; []
    Keywords : Quantum chemistry; quantum chemistry; coupled-cluster; density functional theory; meta-GGA; reaction mechanism; potential energy surface; isomerization; fragmentation; dissociation; condensation; addition; SH2; hydrogen abstraction; iodine atom transfer; complex; weakly interacting system; hyperfine coupling constant; Kvantkemi;

    Abstract : Quantum chemical calculations have been performed to investigate radical cation rearrangement, radical carbonylation, and homolytic substitution reactions of organic molecules. The rearrangement of the bicyclopropylidiene radical cation to the tetramethyleneethane radical cation is predicted to proceed with stepwise disrotatory opening of the two rings. READ MORE
