P-25: Effect of Olive Leaf Extract (OLE) on Rooster Sperm Viability During Storage for 48 hours at 4

Viviparus ater hemocyanin: investigation of the dioxygen-binding site and stability of the oxy- and apo-forms.

The active site of Viviparus ater (mollusc) hemocyanin was investigated using the fact that the binding of dioxygen to the binuclear copper-containing sites of hemocyanins is connected with the appearance of specific dichroic bands which are very sensitive to changes in the structrure and polarity of the environment. Oxy-Viviparus ater hemocyanin exhibits near UV and visible circular dichroism ...

Decomposition of H*-Algebra Valued Negative Definite Functions on Topological *-Semigroups

In the present paper, among other results, a decomposition formula is given for the w-bounded continuous negative definite functions of a topological *-semigroup S with a weight function w into a proper H*-algebra A in terms of w-bounded continuous positive definite A-valued functions on S. A generalization of a well-known result of K. Harzallah is obtained. An earlier conjecture of the author ...
