The fine structure of reconstructed neural retina formed from dissociated neural retinal cells of 6^-day-oId chick embryos on the chorio-allantoic membrane of chick embryos was examined with the electron microscope. Three nuclear layers (ganglion cell Jayer, inner and outer nuclear layers) and two fibrous layers (inner and outer plexiform layers) are found within the reconstructed retina. Both ...

following recent works of several authors like huilgol, bhattacharya etd. and javadpour et al., this paper is to contribute further to the literature of axial flow in a rotational coaxial rheometer. we consider axial flow of herschel bulkley mode1 between two concentric cylinders with the inner one rotating, while the outer cylinder is held stationary. an attempt has been made to direct the ana...

Advances in the additive manufacturing technology have led to the production of complex microstructures with unprecedented accuracy and due todesigning an effective implant is a major scientific challenge in bone tissue regeneration and bone growth. In this research, titanium alloy cylindrical scaffolds with three-dimensional architectures have been simulated and compared for curing partial bon...

the nitrite ® nitro isomerization in nitritopentaamine cobalt (iii) halides has been known. in this paper, the effect of the size of the counter ions (noncoordinated groups) on the rate of isomerization in nitritopentaamine cobalt (iii) halides, is reported. the rate of isomerization is decreased by increasing the size of the counter ions. this decrease is explained on the basis of steric inter...

The retina is a many layered structure and retinal dystrophies may affect any of the layers. From the vitreous to the choroid these are the internal limiting membrane, nerve fibre layer, ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, external limiting membrane, rod and cone inner and outer segments and the retinal pigment epithelium ...

Mathematical robust model of thermo-balance of Earth’s heat fluxes is suggested for such an estimation. Using well-known data (albedo of the Earth’s surface, constant of heat flux from the Sun per square meter of Earth’s outer atmosphere surface, etc.), we could conclude that heating only by the Solar activity is not sufficient to obtain the real meaning of temperature of Earth’s surface. Estim...

Mathematical model of thermo-balance of Earth’s heat fluxes is suggested for such an estimation. Using well-known data (albedo of the Earth’s surface, constant of the heat radiation from the Sun per square meter of Earth’s outer atmosphere surface, etc.), we could conclude that the process of heating only by the Solar activity is not sufficient to obtain the real meaning of the temperature of E...
