    Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

    Sammanfattning : This thesis is divided into three parts: Part 1: Synthesis and conformational analysis of cyclic RNAs, and comparison with lariat RNAs modelling the lariat formed during processing of Group II and Nuclear pre-mRNA. Synthesis of a hexameric lariat RNA model with a tetranucleotidyl "2' → 5' loop" and a dinucleotidyl "3'-tail" has been accomplished. LÄS MER

  3. 3. Charged Polymers: From DNA to Polyampholytes

    Detta är en avhandling från Theoretical Chemistry, Lund University

    Författare :Malek O Khan; Lunds universitet.; Lund University.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computational steering; DNA condensation; ion correlations; electrostatic interactions; colloidal stability; polyampholytes; Monte Carlo simulations; polyelectrolytes; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : Popular Abstract in Swedish Polymerer är långa kedjeliknande molekyler som är vanligt förekommande i naturen och även i många tekniska sammanhang. I lösning är polymerer ofta laddade. De kallas för polyelektrolyter om de har en sorts laddning och polyamfolyter om de har både positiva och negativa laddningar. LÄS MER

    Sammanfattning : Diabetes mellitus is one of the most threatening epidemics of modern times with rapidly increasing incidence. Vanadium and peroxovanadium compounds have been shown to exert insulin–like actions and, in contrast to insulin, are orally applicable. However, problems with side–effects and toxicity remain.
