A coupled modeling framework is used in this study to investigate the effect of subgrid-scale rainfall variability on the spatial structure of the evolving storm and on other surface variables and water and energy fluxes. The Fifth-Generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model coupled with the Biosphere–Atmosphere Transfer Scheme is combined w...

Introduction: The cholinergic system plays an important role in learning and memory. Administration of either extracts of Crocus Sativus (Saffron) or its constituent, crocin, reduced ethanol-induced memory impairment. Based on the above findings, we investigated the effect of crocin in antagonizing spatial learning and memory impairment induced by scopolamine, a cholinergic receptor antagoni...

nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...

background: in recent times, the decreasing groundwater reserves due to over-consumption of water resources and the unprecedented reduction of precipitation, during the past 1 decades, have resulted in a change in the volume and quality of water with time. the aim of this study was to determine the spatial and temporal variations of hardness and total dissolved solids in drinking water resource...

introduction: the conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. although the polymer gel dosimetry method based on magnetic resonance imaging (mri) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...
