  1. 1. Sorption of Cs, Ba, Co, and Eu onto biotite: experiments and modelling

    Författare :Pawan Kumar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cs; Biotite; Ba; titration; Eu; Co; Surface Complexation; Sorption;

    Sammanfattning : The sorption of 134Cs, 133Ba, 60Co and 152Eu, all at about [~10-8 M] onto biotite mineral was studied using the batch method with S: L = 1:50 at three different ionic strengths (0.001, 0.01 and 0.1M NaClO4) and five different pH (5,6,7,8,9) at 25°C for up to two months in an inert atmosphere glovebox.

  3. 2. Targeting RNA by the Antisense Approach and a Close Look at RNA Cleavage Reaction

    Författare :Jharna Barman; Lars Baltzer; Roger Strömberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; mRNA targeting; antisense oligonucleotides; target affinity; RNase H; Michaelis-Menten kinetics; exo-nuclease stability; NMR; pH titration; alkaline hydrolysis; Organisk kemi;

    Sammanfattning : This thesis summarizes the results of studies on two aspects of nucleic acids. Chemically modified antisense oligonucleotides (AONs) have been evaluated with regards to their suitability for mRNA targeting in an antisense approach (Paper I – III). LÄS MER

  4. 3. Trapping Tyrosine Z : Exploring the Relay between Photochemistry and Water Oxidation in Photosystem II

    Författare :Johannes Sjöholm; Stenbjörn Styring; Fikret Mamedov; A. William Rutherford; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photosystem II; Tyrosine Z; EPR; proton-coupled electron transfer; hydrogen bond; pH;

    Sammanfattning : Photosystem II is unique! It remains the only enzyme that can oxidize water using light as energy input. Water oxidation in photosystem II is catalyzed by the CaMn4 cluster. The electrons extracted from the CaMn4 cluster are transferred to P680+ via the tyrosine residue D1-Tyr161 (YZ). LÄS MER

  5. 4. Alloimmunization during pregnancy with special emphasis on anti-D : Laboratory and clinical management

    Författare :Derek Filbey; Lennart Rydberg; Linköpings universitet; []
    Nyckelord :Alloimmunization in pregnancy; Anti-D; Haemolytic disease of the newborn HDN ; IAT-titration; AA-quantitation; Chemiluminescence test; Category D; HLA class II antibodies; MEDICINE; MEDICIN;

    Sammanfattning : The laboratory and clinical management of alloimmunized in pregnancy has been investigated according to a protocol currently in use in Örebro region. A 12 year epidemiological study showed the prevalence of alloimmunization to be 0.57% in this Swedish populationwith a 0. LÄS MER

  7. 5. Feasibility study of soil washing to remediate mercury contaminated soil

    Författare :Jingying Xu; Bo Lind; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil remediation; pH-dependentdissolution; organic matter; mobilisation; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Mercury (Hg) cannot be degraded. Therefore only two principal processes are available for the treatment of Hg-contaminated soil: (1) the separation of Hg from the soil or (2) the stabilisation of Hg within the soil. Prior to selecting a suitable treatment technique, it is necessary to have an understanding of Hg behaviour in contaminated soil, i.e. LÄS MER
