    Thermal Study of a Newly Synthesized Cu(II) Complex Binding to Bovine β-Lactoglobulin by Adeleh Divsalar, Lyla Barzegar, Gholamreza Rezaei Behbehani

    Published 2013-01-01
    “…The heats of BLG + Cu(II) interactions are reported and analyzed in terms of the extended solvation theory for calculation of binding and thermodynamic parameters of the interaction. The results suggested that binding of Cu(II) complex on BLG resulted in significant changes on the tertiary structure and conformation of protein via increasing of hydrophobicity and inducing partially unfolded structure in BLG which has a good agreement with the solvation parameters recovered by the extended solvation model suggesting destabilization of the protein.…”

    Energetics and phase diagrams of Fe-Cr and Co-Cr systems from first principles by Vreštzál J., Houserová J., Šob M.

    Published 2002-01-01
    “…The structural energy differences, calculated by FLAPW (Full potential augmented plane wave) method, enable us to utilize a more complete physical information about total energy of intermetallic phases and to propose a new model for their thermodynamic description. Our approach is based on the two-sublattice model, similarly as for solid solution phases, but the structural energy differences for end-members in the metastable or unstable structures are obtained by means of first-principles electronic structure calculations. …”

    Correcting Fast-Mode Pressure Errors in Storm-Scale Ensemble Kalman Filter Analyses by Corey K. Potvin, Louis J. Wicker

    Published 2013-01-01
