Soil infiltration is a very important concept in hydrology as well irrigation, which plays vital role estimating surface runoff and groundwater recharge. It complicated process that varies with numerous factors. Accurate estimation of soil required for future many other purposes. To estimate the process, there are models. The majority them have some presumptions, unique calculation method, limi...
stem cells are self-renewing cells that can be differentiated into other cell types. conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2d) cultures. the design of three-dimensional (3d) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...
Accurate estimation of water infiltration into the soil is important for the design of irrigation systems. Therefore, calibration of different models is necessary to estimate the permeability in different regions. The aim of the present study was to calibrate and evaluate the models of Kastiakov, Kastiakov modified, Philip, SCS, Novell, and Horton in different soil textures. To evaluate the acc...
over-exploitation of groundwater resources in Chaharmahal va Bakhtiari province led to prohibition of some plains in this province. One of these plains is Sefiddasht aquifer. Artificial recharge can be an effective method to raise the groundwater table and resolve the groundwater crisis in this province. The most important step for successful accomplishment of artificial recharge is locating su...
Spatially homogeneous Bianchi type-II, VIII and IX anisotropic, as well as isotropic cosmological models can be obtained in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) when the source for energy momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings. All the models obtained and presented here are expanding, non-rotating and accelerating...
