In this study we first evaluate the time between collisions related to the transport properties in liquid water, provided by the protons motion tied to the hydrogen bonds. As water is an essential substance for the establishment of life in the living beings, we take this time as the basic unit to measure some kinds of retention time related to their memory. Besides this, integration is an impor...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
Long-term potentiation of synpatic transmission (LTP) of the perforant path--dentate gyrus synapse is induced by 5 Hz, theta-like stimulation patterns. Such stimuli induce plasticity that is most likely driven by a decrease in synaptic inhibition (disinhibition) mediated by GABAB autoreceptors. In the present study, we demonstrate that LTP induced in this manner is completely antagonized by eth...
