the development of culture media able to mimic the preovulatory stage of follicular environment and support nuclear and cytoplasmic maturation of oocyte is important for in-vitro fertilization (ivf) programs. it seems that the best culture media for embryonic development and cell cleavage is the natural composition which surrounds the oocyte which has been used occasionally in human ivf program...

This paper is concerned with the surface and small scale effects on transverse vibration of a viscoelastic single-layered graphene sheet (SLGS) subjected to an in-plane magnetic field. The SLGS is surrounded by an elastic medium which is simulated as Visco-Pasternak foundation. In order to investigate the small scale effects, the nonlocal elasticity theory is employed due to its simplicity and ...

five different media with two concentrations and kinds of carbohydrates and peptone treatments were examined for their effectiveness in promoting asymbiotic seed germination of epipactis  veratrifolia. results revealed significant differences between media on seed germination percentage and protocorm growth and fast medium has the best effect on both. carbohydrate treatments had significant eff...

natural convection heat transfer from a vertical heated plate in a saturated porous medium is analyzed under thermal non-equilibrium assumptions. the plate is maintained at a non uniform temperature and the fluid is considered to be with internal heat generation. the coupled momentum and energy equations for fluid and solid phases are transformed to a similarity format, and solved numerically. ...
