  3. 22. Formulations, Release and Skin Penetration of Topical Anesthetics

    Författare :Katayoun Welin-Berger; Brian W. Barry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Sammanfattning : This thesis describes certain critical aspects of the development of semisolid topical anesthetic formulations requiring a fast onset of action. Furthermore, local anesthetics were investigated regarding their phase interaction with membrane lipids. LÄS MER

  4. 23. Rock mass response during high pressure grouting

    Författare :Rikard Gothäll; Håkan Stille; Johan Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : The sealing of hard jointed rock by grouting involves several complicated mechanical systems. The result is a complex coupled system of hydro- logical and mechanical precesses. In order to determine the higher order effects of the resulting system the fracture deformations must be assessed. LÄS MER

  5. 24. Grout Development and Methods for Remedial Grouting of Embankment Dams

    Författare :Johan Lagerlund; Jan Laue; Peter Viklander; Markus Aufleger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : An embankment dam can be damaged by internal erosion. During this process, the soil material erodes and is transported out of the dam structure. Some common types of damage due to internal erosion are piping, less dense soil zones, and zones where the fine material has been washed out. LÄS MER

  7. 25. Thin films of molecular sieves : synthesis and applications

    Författare :Jonas Hedlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The seed film method for synthesis of ultra thin and thin molecular sieve films was developed. The versatility of the method was demonstrated by successful preparation of films of a number of molecular sieves (silicate-1, ZSM-5, NA) on various supports (silicon, alumina, gold, etc.). LÄS MER
