koopan regional laterites located in north east of shiraz, fars province.the rock strata, koopan laterits set on neyriz ophiolites that these ophiolites are actually part of a series zagros ophiolite with of upper cretaceous age. these laterites are covered with nummulitic limestone equivalent jahrom formation with eocene age. the lateritization should be occurred after the upper cretaceous in ...

background: new treatment modalities are developed with the aim of escalating tumor absorbed dose and simultaneously sparing the normal structures. the use of nanotechnology in cancer treatment offers some possibilities including destroying cancer tumors with minimal damage to healthy tissues. zinc oxide nanoparticles (zno nps) are wide band gap semiconductors and seem to have a good effect on ...

When solving the Laplace equation numerically via computer simulation, in order to determine field values at surface of a shape model that represents emitter, it is necessary define simulation box and, within this, domain. This domain must not be so small boundaries have an undesirable influence on predicted values. A recent paper discussed situation cylindrically symmetric emitter models stand...
