  2. 1. Perplexing Protein Puzzles

    Author : Stina Lindman; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calbindin D9k; split-GFP; protein G B1; pKa-values; protein reconstitution; Electrostatic interactions; protein stability; protein denaturation; heteronuclear NMR; pH titrations;

    Abstract : Protein structure and stability are inherent in the amino acid sequence and governed by non-covalent interactions. The cooperation between forces is, however, perplexing and not well understood. In order to elucidate and predict protein folding and stability, detailed studies of non-covalent interactions are required. READ MORE

  4. 2. Uncertainties in Actinide Solubility Calculations Illustrated using the Th-OH-PO4 System

    Author : Christian Ekberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; potentiometric titrations; solvent extraction; uncertainty analysis; sensitivity analysis; MINVAR; thorium hydrolysis; SENVAR; thorium phosphate complexes; UNCCON;

    Abstract : Computer simulations have become increasingly popular in many different areas over the years, owing mainly to more effective and cheaper machines. In many cases, the trend seems to be that computer simulations are replacing experiments, at least in areas in which experiments are very difficult (expensive) or impossible. READ MORE

  5. 3. Physico-chemical properties of some aquatic fulvic acids - functional groups and stability

    Author : Irina Valarié; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Humic material constitutes a category of naturally produced organicmacrocompounds, widely spread in both terrestrial and aquatic systems and accounting for up to 70% of the total soil carbon and 50% of the dissolved organic carbon in surface waters. Humic material is formed as the result of complex chemical transformations of biomass. READ MORE

  6. 4. Towards More Specific Microcalorimetric Studies With Special Emphasis on Biological Systems

    Author : Peter Johansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; isothermal heat conduction micro calorimetry spectrophotometry diode array pH oxygen titration chemical reaction biological bacteria perfusion photo carbon dioxide plant enthalpy Gibbs energy kinetic; Biology; Biologi;

    Abstract : A new approach in isothermal heat conduction microcalorimetric studies of chemical and biological processes is explored. The general (non-specific) method of calorimetry is combined with more specific analytical methods of analysis to "multi-functional microcalorimetric process monitors". READ MORE

  7. 5. Chlorite: Geochemical properties, Dissolution kinetcis and Ni(II) sorption

    Author : Åsa Zazzi; Zoltan Szabo; Susanna Wold; Peter Vilks; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chlorite; dissolution kinetics; Ni II sorption; surface complexation; Chemistry; Kemi;

    Abstract : In Sweden, among other countries, a deep multi-barrier geological repository, KBS-3, is planned for the burial of nuclear waste. One of the barriers is identified as the grantic bedrock itself and in this environment chlorite is present at surfaces in fracture zones. READ MORE
