the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Unusual thermal diffusion in polymer solutions.
Thermal diffusion forced Rayleigh scattering results on thermal diffusion of poly(ethylene oxide) (PEO) in ethanol/water mixtures are presented. In water-rich solvent mixtures, PEO is found to migrate towards regions of lower temperature. This is typical for polymer solutions and corresponds to a positive Soret coefficient of PEO. In solvent mixtures with low water content, however, the polymer...
متن کاملViscoelastic effect on nucleation in semidilute polymer solutions
We study the growth of droplets consisting mostly of solvent in a metastable semidilute polymer solution. We introduce a modified Gibb~Thomson relation at the interface which accounts for viscoelastic effects. The growth is much decelerated when the radius is shorter than a long viscoelastic length. Not enough attention has yet been paid to nucleation phenomena in polymeric
متن کاملEffect of Polymer Grade and Plasticizer Molecular Weights on Viscoelastic Behavior of Coating Solutions
Film coating solutions containing different grades of HPMC (E5, E15 and E50) with and without polyethylene glycol (with various molecular weights) were examined by an oscillatory method, using Haake CV 100 rheometer. Fundamental rheological parameters (?, G? and G² ) were measured over the frequency range from 0.04 to 2 Hz. The variation with frequency of the loss tangent (a ratio of viscous to...
