  1. 1. A scattering study of concentrated lens protein solutions and mixtures - Towards understanding the molecular origin of presbyopia

    Författare :Saskia Bucciarelli; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scattering; eye lens; presbyopia; dynamical arrest; crowding; proteins; dynamics; crystallins;

    Sammanfattning : Healthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. LÄS MER

  3. 2. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers

    Författare :Gisela Richardson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; image analysis.; rheology; microscopy; amylose-lipid complex; gelatinization; dynamical arrest; amylose; starch; sponge cake; foam; emulsifier; alpha-gel; physical state;

    Sammanfattning : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.

  4. 3. Computer simulations of condensed phases with icosahedral local order

    Författare :Sergei Simdyankin; Paul Madden; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; simple liquids; glasses; liquid-glass transition; Frank-Kasper phase; molecular dynamics; phonon dispersion; normal-mode analysis; wavelet analysis; numerisk analys; Numerical Analysis;

    Sammanfattning : Understanding the fundamental aspects, and the formation mechanisms of glasses remains an outstanding unsolved problem of condensed-matter physics.Glass-formation in simple atomic systems is generally associated with the icosahedral local order. LÄS MER
