Background: The development of a reliable method for the cryopreservation of mammalian ovary would be an important advancement in the field of reproductive biology for the preservation of genetic resources. The cryopreserved follicles have the potential to develop in-vitro; however, the developmental rate is lower than that of fresh follicles. Researchers have used that of different cryoprotect...

Numerical simulation is a comprehensive tool in modern process development which is extensively used for promotion of crystal growth processes. Multi-crystalline silicon is an important material with advantages of low-production cost and high conversion efficiency of PV solar cells. The control of grains as well as the grain boundaries is particularly important to the crystal quality and thus t...
Risks assessment of forest project implementation in spatial density changes of forest under canopy vegetation using artificial neural network modeling approach Nowadays, environmental risk assessment has been defined as one of the effective in environmental planning and policy making. Considering the position and structure of vegetation on the forest floor, the main role of forest under ca...
