  1. 11. Numerical Modelling and Statistical Analysis of Ocean Wave Energy Converters and Wave Climates

    Författare :Wei Li; Isberg Jan; Jens Peter Kofoed; Uppsala universitet; []
    Nyckelord :Wave power; Wave energy converter; Gravity-based foundation; Power absorption; Wave spectrum; Linear generator; Frequency domain; Wave climate; Ocean wave modelling; Mixed-distribution model; Bivariate distribution; Archimedean copula;

    Sammanfattning : Ocean wave energy is considered to be one of the important potential renewable energy resources for sustainable development. Various wave energy converter technologies have been proposed to harvest the energy from ocean waves. This thesis is based on the linear generator wave energy converter developed at Uppsala University. LÄS MER

  3. 12. NMR Self-Diffusion Studies and Stability Studies of Emulsions

    Författare :Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

    Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER

  4. 13. Estimating income inequality : large sample inference in finite populations

    Författare :Arne Sandström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; order statistics and concomitant of order statistics; functionals; stochastic differentials; weighted empirical distribution function; income inequality; Gini coefficient;

    Sammanfattning : During the last decades the interest in measuring income inequality has substantially increased. In this work we consider measures related to the Lorenz Curve, e g the Gini coefficient. These measures are decomposable^ g the inequality in disposable income can be assigned to various income sources. LÄS MER

  5. 14. Role of the Blood-Brain Barrier in Stereoselective Distribution and Delay in H1 Receptor Occupancy of Cetirizine in the Guinea Pig Brain

    Författare :Anubha Gupta; Margareta Hammarlund-Udenaes; Niclas E. Jonsson; Joseph W. Polli; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Cetirizine enantiomers; Brain distribution; Microdialysis; H1 receptor occupancy; Stereoselective-pharmacokinetics; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI;

    Sammanfattning : Cetirizine, an H1-antihistamine, is prescribed for allergic disorders. It exists as a racemic mixture, with levocetirizine being the active enantiomer. The central nervous system side-effects of H1-antihistamines are caused by their penetration into the brain. LÄS MER

  7. 15. Modeling of Hindered Diffusion in Gels

    Författare :Jan Gutenwik; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective diffusion coefficient; pore size distribution; obstruction; immobilization; modeling; adsorption kinetics; hindered diffusion; simulation program; proteins; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Hindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. LÄS MER
