Gelatinisation and retrogradation of starch in wheat flour systems and whole wheat grains were studied using differential scanning calorimetry (DSC) and the impact of these events on starch digestibility was investigated. Retrogradation of starch was studied with partially and fully cooked (boiled at 100°C for 12 min and 32 min, respectively) wheat grains that were subjected to storage at 22°C ...

The processes of six-quark production with one bb̄ pair are studied by means of a complete tree-level electroweak calculation. The top-quark signal is examined: the importance of electroweak backgrounds, of the order of 10% above the tt̄ threshold and of about 30% of the purely electroweak signal at threshold, is further stressed by studying the dependence of the cross-section at threshold on the...

Hydrogen dissociation on silicon surfaces is strongly activated both by kinetic energy of the H2 molecules as well as by surface temperature. The latter effect is correlated to the dynamical generation of lattice distortions which possess a higher reactivity, similar to static lattice distortions at steps or defects. They lead to a broad distribution of barriers in adsorption which result in a ...

We study the evolution of heavy quarkonium states with temperature in a Quark-Gluon Plasma by evaluating an in-medium Q ¯ Q T −matrix within a reduced Bethe-Salpeter equation in S− and P −wave channels. The interaction kernel is extracted from finite-temperature QCD lattice calculations of the singlet free energy of a Q ¯ Q pair. Quarkonium bound states are found to gradually move across the Q ...
