  1. 6. Suspensions of finite-size rigid particles in laminar and turbulent flows

    Författare :Walter Fornari; Luca Brandt; Jérémie Bec; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspensions; complex fluids; sedimentation; rheology; turbulence;

    Sammanfattning : Dispersed multiphase flows occur in many biological, engineering and geophysical applications. Understanding the behavior of suspensions is a difficult task. In the present work, we numerically study the behavior of suspensions of finite-size rigid particles in different flows. LÄS MER

  3. 7. Methods for analysis of heart function

    Författare :Håkan Kronander; KTH; []
    Nyckelord :;

    Sammanfattning : There is a continuous demand for improvements in methods foranalysis of heart function. This thesis investigates both themeasurement of left ventricular (LV) volume for evaluating theheart function and the exercise electrocardiographic (ECG) testfor diagnosis of coronary artery disease (CAD).

  4. 8. Short-term pulmonary side-effects following radiation therapy in breast cancer

    Författare :Pehr Lind; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :breast neoplasm; radiotherapy; pulmonary side-effects;

    Sammanfattning : The purpose of this dissertation was to study the short-term pulmonary side-effects following adjuvant radiotherapy for breast cancer in terms of clinical pulmonary complications, loss of pulmonary function and radiological abnormalities, and the association to irradiated lung volume and dose. Furthermore, we wanted to estimate the influence of covariates, e. LÄS MER

  5. 9. Kemistudenters föreställningar om entalpi och relaterade begrepp

    Författare :Tor Nilsson; Hans Niedderer; Kjell Waltersson; Roland Kjellander; Mälardalens högskola; []
    Nyckelord :enthalpy; thermodynamics; chemistry; chemistry education; conceptions; higher education; entalpi; termodynamik; kemi; kemididaktik; ämnesdidaktik; föreställningar; begrepp; begreppsbildning; högre utbildning; naturvetenskapernas och teknikens didaktik; naturvetenskapernas och teknikens didaktik;

    Sammanfattning : The aim of this thesis was to construct undergraduate chemistry students’ conceptions of enthalpy and its change, internal energy and its change, heat and work. Conceptions make it possible to identify students’ problems with the taught content. How students’ exam results are affected by qualitative/conceptual questions was also investigated. LÄS MER

  7. 10. Roles of intermolecular interactions in amyloid fibril formation mechanisms

    Författare :Tony Werner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; disulfide-bonds; Atox1; α-synuclein; Aggregation; protein interactions; Parkinson’s disease; β-parvalbumin; macromolecular crowding; osmolytes; Amyloid fibrils;

    Sammanfattning : Amyloid fibrils, a major pathological feature of several neurodegenerative disorders, are highly stable, insoluble aggregates of misfolded proteins. The formation of such aggregates involves a complex equilibrium between protein monomers, different on- and off-pathway transient oligomeric species, and amyloid fibrils. LÄS MER
