  1. 1. Bacterial adhesion to polyelectrolyte modified materials based on nanocellulose

    Författare :Jonatan Henschen; Lars Wågberg; Per Larsson; Josefin Larsson; Aji Mathew; Michael Malkoch; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bacterial adhesion; cellulose nanofibrils; polymer adsorption; polyvinylamine; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Since the introduction of materials based on cellulose nanofibrils (CNFs), these materials have been studied extensively and are suggested to be suitable for use in, for example, hygiene and health care products. A property not very well studied but that could further increase the usability of CNF products is the possibility of controlling bacterial adhesion to the materials. LÄS MER

  2. 2. Natural products from nonracemie building blocks : synthesis of pine sawfly pheromones

    Författare :Michael Larsson; Torbjörn Norin; Gunnar Westman; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Total synthesis; diastereoselective addition; dimethylzinc; Lewis acid; alkyllithium; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes a number of synthetic approaches for obtaining chiral, enantiomerically pure natural products, in particular some semiochemicals. This has been accomplished by using various strategies; by starting from compounds from the chiral pool, by using chiral auxiliaries, via enzymatic resolutions or by chemical asymmetric synthesis.

  3. 3. Study of High Efficiency Phase-Only Diffractive Optical Elements

    Författare :J. Michael Larsson; Chalmers University of Technology; []
    Nyckelord :array illuminators; computer generated phase holograms; computer simulations; diffractive bifocal intraocular lenses; kinoforms; design; manufacture; diffractive optical elements; evaluation; simulation;

    Sammanfattning : This work deals with the design, simulation, manufacture, and evaluation of diffractive optical elements. Particularly, kinoforms and diffractive bifocal intraocular lenses are studied. Evaluation of kinoforms, i.e. LÄS MER

  4. 4. Yrrunan : Användning och ljudvärde i nordiska runinskrifter

    Författare :Patrik Larsson; Michael Lerche Nielsen; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Scandinavian languages - general; runes; runic inscriptions; the ýr-rune; the reið-rune; palatal r; alveolar r; palatalization; phonemic and phonetic merger; Nordiska språk - allmänt; Scandinavian languages; Nordiska språk; Scandinavian Languages; Nordiska språk;

    Sammanfattning : The main purpose of this dissertation is to study the use of the ýr-rune in Scandinavian runic inscriptions. The rune, in the shapes m (older) and z (younger), originally denoted /R/, i.e. palatal r, which eventually merged with /r/. LÄS MER

  5. 5. Att beskriva kronisk smärta : en lärprocess

    Författare :Michael Peolsson; Ullabeth Sätterlund Larsson; Roger Säljö; Linköpings universitet; []
