  4. 2. Structural Transitions in Helical Peptides : The Influence of Water – Implications for Molecular Recognition and Protein Folding

    Author : Martin Lignell; Hans-Christian Becker; Kaare Teilum; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; protein folding; molten globule; time-resolved fluorescence spectroscopy; CD spectroscopy; molecular recognition; structure-function paradigm; Chemical physics; Kemisk fysik; Physical Chemistry; Fysikalisk kemi;

    Abstract : Fluctuations in protein structure are vital to function. This contrasts the dominating structure-function paradigm, which connects the well-defined three-dimensional protein structure to its function. However, catalysis is observed in disordered enzymes, which lack a defined structure. READ MORE

  5. 3. Sparse Matrices in Self-Consistent Field Methods

    Author : Emanuel Rubensson; Pawel Salek; Hans Ågren; Anders Niklasson; Axel Ruhe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sparse matrix; self-consistent field; Hartree-Fock; Density Functional Theory; Density Matrix Purification; Theoretical chemistry; Teoretisk kemi;

    Abstract : This thesis is part of an effort to enable large-scale Hartree-Fock/Kohn-Sham (HF/KS) calculations. The objective is to model molecules and materials containing thousands of atoms at the quantum mechanical level. HF/KS calculations are usually performed with the Self-Consistent Field (SCF) method.

  6. 4. Polska socrealistyczna krytyka literacka jako narzedzie wladzy

    Author : Dorota Tubielewicz Mattsson; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Slavic and Baltic languages - general; Slaviska och baltiska språk - allmänt; Slavic languages; Slaviska språk; slaviska språk; Slavic Languages;

    Abstract : In the dissertation I analyze the relationship between Socialist Realism (SR) and literarycriticism in Poland during the years 1945-54. I suggest that literary criticism played akey role in promoting SR. SR was possible partly because of political pressure andpartly because it built on progressive ideas and values developed over the centuries. READ MORE

  7. 5. Stable isotope studies of contaminant and material transport in Baltic pelagic food-webs

    Author : Carl Rolff; Nicholas J.P Owen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; zoologi; Zoology;

    Abstract : Both carbon and nitrogen appear in nature as different stable isotopes. Many natural processes affect the relative proportions of heavy and light isotopes in predictable ways. The isotopic composition of organisms and other organic materials can therefore serve as records of the processes involved in their formation. READ MORE
