Two snail species belonging to genus Lymnaea, L.auricularia and L.gedrosiana, were collected from 6 different districts of Shadegan area of Khoozestan. Eight percent of the total collections of the snails revealed the occurrence of larva in them. The prevalence of larva within the snails varied in different districts may be due to different geoclimatic conditions and availability of fresh water...

[1] We explore the mechanisms whereby groundwater influences terrestrial water storage (TWS) in the Amazon using GRACE observations and two contrasting versions of the LEAF-Hydro-Flood hydrological model: one with and the other without an interactive groundwater. We find that, first, where the water table is shallow as in northwestern Amazonia and floodplains elsewhere, subsurface stores (vados...

To better understand groundwater-surface water dynamics in high latitude areas, we conducted a field study at three sites in Alaska with varying permafrost coverage. The natural groundwater tracer ((222)Rn, radon) was used to evaluate groundwater discharge, and electrical resistivity tomography (ERT) was used to examine subsurface mixing dynamics. Different controls govern groundwater discharge...

The initial room-temperature interactions of water vapor with polycrystalline bulk annealed uranium surfaces were studied by combined measurements utilizing Direct Recoil Spectrometry (DRS) and X-ray Photoelectron Spectroscopy (XPS). It was found that the water goes through a complete dissociation into oxidic oxygen and two neutral H atoms throughout the whole exposure range. The process procee...

The corrosion inhibition of API 5L X60 pipeline steel in oil well acidizing fluid stimulated with 1.0 M HCl by Tranexamic Acid (TXA) was investigated using potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS) and the conventional gravimetric or weight loss (WL) techniques at temperatures ranging from 303 to 323 K. Surface morphological analysis was carried out us...

Water quality is highly affected by riverside vegetation in different regions. To comprehend this research, the study area was parted into wet and dry The WASP8 applied for simulations of water profile over both Waterways selected from each region. It found that Ara Waterway, located regions, has a higher variation seasonal scale than Yamuna which interrelationship between river variables NDVI ...

[1] This study presents the first comparison of seasonal groundwater storage (GWS) variations derived fromGRACE satellite data with groundwater-level measurements in the High Plains Aquifer, USA (450,000 km). Correlation between seasonal GRACE terrestrial water storage (TWS) and the sum of GWS estimated from field measurements (2,700 wells) and soil moisture (SM) simulated by a land surface mod...

This paper presents user-friendly SAS macro and SAS programs to check the three parts of a time series: Trend, Cyclical patterns, and Stationarity. The SAS macro KENDALL performs the trend analysis. Seasonal Kendall Trend analysis, including summery statistics; overall Tau and the P-value of the test for trend; monthly Tau values, the corresponding P-values for each month; the Seasonal Kendall ...
