The binding data for interaction of a homologous series of n-alkyl sulfates with alkyl chainlengths from C8 to C12 with insulin were analyzed on basis of Hill equation for two classes ofbinding sites .The intrinsic Gibbs free energies were calculated and resolute on basis ofelectrostatic and hydrophobic contributions The estimation of these contributions reveals themajor role of electrostatic i...

the interaction of the external donor (propyltrimethoxysilane - ptms) with titanium-magnesium catalysts (tmcs) containing dibutylphthalate (dbp) as internal donor, which were prepared in different ways, was studied by chemical analysis and infrared diffuse reflectance spectroscopy (drifts). the chemical composition of the catalysts after their interaction with heptane solutions of ptms, ptms/al...

The adaptive responses of crop genotypes and patterns of genotype x location (G x L) interaction are important to crop improvement as they are the basis for selection for specific adaptation and for elucidation of the causes of G x L interaction. Their legitimate assessment, however, requires yield data for the test genotypes for a large number of sites and over multiple years. Such data are se...
