Background and Purpose: Nitrate is considered as a major pollutant for groundwater resource. In recent years, the concentration of nitrate in subsurface water is increasing because du to utilization of the of using excessive amount of fertilizers and disposal of wastewater in soils. This research was carried out as descriptive study, in a rural area of Paeen Khiaban Litkooh in Amol City in 20...
Reflected light photometry of terrestrial exoplanets could reveal the presence oceans and continents, hence placing direct constraints on current long-term habitability these worlds. Inferring albedo map a planet from its observed curve is challenging because different maps may yield indistinguishable curves. This degeneracy aggravated by changing clouds. It has previously been suggested that d...
The magnetic properties of an anisotropic Sm2Fe17N3 magnet powder were improved by enhancement of nitrogenation homogeneity. We made the Sm2Fe17 parent material powder by a reduction-diffusion method which contains a reduction-diffusion heat treatment and a subsequent wet process for removal of a CaO by-product. In the present study, as the modified process for the magnet powder, the nitrogenat...
Snow monitoring is essential for prediction of flooding due to rapid snowmelt, to provide snow avalanche risk forecasts and for water resource management – including hydropower production, agriculture, groundwater and drinking water. Sentinel-1 C-band SAR is sensitive to presence of wet snow and can be used to binary snow-wetness classification. Wet-snow mapping into more categories has been de...
