  1. 21. NMR Studies of Colloidal Systems in and out of Equilibrium

    Författare :Pavel V. Yushmanov; Peter Stilbs; Terence Gosgrove; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stopped-flow NMR; temperature-jump NMR; crossrelaxation; NMR; NMR probe; fluorosurfactant; micellar kinetics; micellar structure; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The Thesis describes (i) the development of add-on instrumentation extending the capabilities of conventional NMR spectrometers and (ii) the application of the designed equipments and techniques for investigating various colloidal systems. The new equipments are: Novel designs of stopped-flow and temperature–jump inserts intended for conventional Bruker wide-bore superconductive magnets. LÄS MER

  2. 22. Pharmacokinetics and pharmacodynamics of pentoxifylline and metabolites

    Författare :Marie V Magnusson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacokinetics; Pentoxifylline; metabolites; pharmacodynamics;

    Sammanfattning : Pentoxifylline is a haemorheologic drug with complex pharmacokinetics and pharmacodynamics due to both reversible metabolism and the formation of active metabolites. In humans, pentoxifylline is metabolised to at least seven phase 1 metabolites (M1-M7). LÄS MER

  3. 23. Localized carcinoma of the prostate : Aspects on screening, staging, and surgical treatment

    Författare :Knud V. Pedersen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The management of localized carcinoma of the prostate is controversial.Opinions vary about whether screening is appropriate for this particular cancer, about the accuracy of pretreatment staging of the primary tumour, and about the value of potentially curable treatment such as radical prostatectomy.

  4. 24. Long freight trains and long-term rail surface damage

    Författare :Visakh V Krishna; Sebastian Stichel; Mats Berg; Carlos Casanueva; João Pombo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track friendliness; rail surface damage; multi-body simulation; longitudinal train dynamics; track maintenance; rolling contact fatigue; wear; Engineering Mechanics; Teknisk mekanik; Vehicle and Maritime Engineering; Farkostteknik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Sammanfattning : Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. LÄS MER

  5. 25. Experimental and numerical investigations of hydrodynamic focusing of colloidal dispersions

    Författare :V. Krishne Gowda; Fredrik Lundell; Daniel Söderberg; Lynn Walker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; flow focusing; colloidal fiber dispersion; effective interfacial tension; microflow morphology; nanoparticle orientation; Mikrofluidik; flödesfokusering; kolloidala dispersioner; effektiv ytspänning; mikroflödesmorfologi; orientering av nanopartiklar; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Dispersed non-spherical particles are the fundamental constituent of many complex fluids. Such fluids are studied both for their industrial and scientific importance, and for their peculiar functional properties (mechanical, optical, thermal, fluidic). LÄS MER
