soil and water assessment tool model, swat, uses different layers of watershed data which out of soil layer is the important one. soil layer data should be extracted from detailed soil maps. in most developing countries including iran, these detailed maps are not available except for irrigation districts and rarely for dry land farming areas and also for some strategic places of development pur...

abstract- efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. this research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (wp) with different water management scenarios at farm level at ...

BACKGROUND AND AIM: Oral diseases are very important because they impose economic and social burden on societies. Given the resource scarcity, it is necessary to devise cost-effective and scientific strategies to prevent and control oral diseases. This study aimed to estimate the potential cost-savings for dental caries treatment associated with Community Water Fluoridation Program (CWFP) in Ke...

Several shrimp species from the clade Penaeidae are farmed industrially for human consumption, and this farming has turned shrimp into the largest seafood commodity in the world. The species that are in demand for farming are an anomaly within their clade because they grow to much larger sizes than other members of Penaeidae. Here we trace the evolutionary history of the anomalous farmed shrimp...
