Droughts event can be effect on available groundwater and water resources in the many components that it cause deficit. This purpose, for the deal with droughts hazard for make decisions it is necessary to monitoring and assessing droughts feature in point of view concluding severity, geographic extending. In this study the hydrological droughts analyzed based on the clustering, surface water i...
Human activities have profoundly changed the hydrological regime and trends of rivers lakes, which, in turn, has affected utilization their navigable conditions. However, few studies focused on effects changes regimes lakes Thus, this study intensively analyzes investigates depth at major control sections lake area during dry season period before 2002, when Three Gorges Reservoir was not yet co...
The paper aims to examine the impact of financial sanctions on capital inflow and outflow in Iran. The research question is about examining the effect of financial sanctions on FDI inflow and capital outflow in Iran. We used the intervention model as an econometric method to estimate the impact during 2005-2019. The paper discussed three periods. From 2005 to 2010, severe financial sanctions ne...
ABSTRACT Fine sediment stored in the gravel bed is an important component of river systems. Current field protocols usually allow evaluation silt–clay fraction fine stocks only and neglect sand fraction. This study proposes a new protocol to quantify stocks, including inside matrix. were sampled within patches 0.30 m × on dry surface, separating surface layer subsurface layer. The grain‐size di...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Existence of outflow intrusion introduces small-scale turbulence that perturbs the vertically stratified character of the sound velocity and causes spatial and temporal fluctuations of the sound propagation. In this experimental study, we have investigated acoustic wave propagation with frequency of 50 kHz in a pre-stratified environment with intrusion of a turbulent plume while the si...

PURPOSE To determine the day and night differences in intraocular pressure (IOP), aqueous flow, outflow facility, uveoscleral outflow, and central corneal thickness (CCT) in juvenile and adult rabbits. METHODS Studies were performed on twelve 3-month-old and ten 12-month-old male New Zealand White rabbits. Daytime measurements were made between 9 AM (3 hours after lights on) and 3 PM, and nig...
