Henry Darcy's experimental studies in 1856 of saturated water flowthrough a homogeneous porous medium contained in a vertical column have provided the basis for the quantitative description of fluid flow in a wide variety of both natural and engineered porous medium environmental systems. Extrapolation of Darcy's original observations and conclusions has led to several commonly applied equation...
abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
The article is devoted to the development of an optimization procedure for conformance control treatment. Currently, due significant share reservoirs with high water cut, it relevant use methods that allow reducing rate production cut increase.

a study of the crime of hostage-taking in iranian law,and in international documents
Wood is a sustainable material with big sound absorption potential based on its natural porous characteristics. However, the acoustic performance of wood greatly limited by low permeability structures. In this study, we prepared new type cellulose (CW) using two-step delignification process basswood matrix followed supercritical CO2 drying. The as-prepared CW exhibited high air 33.78 Darcys (in...
