Cyclic GMP-specific phosphodiesterase (3',5'-cyclic-nucleotide 5'-nucleotidohydrolase, EC (PDE) is thought to be a key enzyme of the retinal-rod phototransduction cyclic nucleotide pathway. We attempted to investigate the properties and content of PDE in retinal-cone photoreceptors. The fractions obtained from cone-dominant ground squirrel retinas(More)
The paper describes the theoretical framework and results of using an rapid three-dimensional super element model of oil field development. The model makes it possible to speed up calculation of two-phase filtration in an oil reservoir by hundreds of times owing to the use of large computational cells – super elements, the number of which corresponds to the(More)
