groundwater quality management is the most important issue in many arid and semi-arid countries, including iran.artificial neural network (ann) has an extensive range of applications in water resources management. in this study,artificial neural network was developed using matlab r2013 software package, and cl, ec, so4 and no3 qualitativeparameters were estimated and compared with the measured ...

This study is an attempt to introduce scientific fundamentals and available methods for wellhead protection area (capture zone) delineation for drinking water wells in cities. The results of this study could obviate some demands of the national water and wastewater company in quality control of the drinking water resources by delineation and application of the wellhead protection areas. For thi...

1 This educational resource summarises recent developments in sunscreen research, knowledge, and use. It starts with a review of the Nambour Skin Cancer Prevention Trial, which contributes to the evidence for a protective effect of sunscreen against melanoma. This is followed by consideration of UVA protection, correct application of sunscreen, skin type in sun protection, and compliance with s...

Water reclamation and reuse provides a unique and viable opportunity to augment traditional water supplies. As a multi-disciplined and important element of water resources development and management, water reuse can help to close the loop between water supply and wastewater disposal. Effective water reuse requires integration of water and reclaimed water supply functions. The successful develop...

Fisheries resources in the Caribbean suffer intense pressure from overharvesting. Some of the most valuable fisheries in The Bahamas, such as queen conch (Strombus gigas), spiny lobster (Panulirus argus), and Nassau grouper (Epinephelus striatus), are overexploited and require additional protection. Despite these pressures, we currently know very little about the factors that underlie local res...

In this data article, we evaluated the daily fluoride contents in 20 household desalinators working by reverse osmosis (RO) process in Bushehr, Iran. The concentration levels of fluoride in inlet and outlet waters were determined by the standard SPADNS method using a spectrophotometer (M501 Single Beam Scanning UV/VIS, UK). The fluoride content in outlet waters were compared with EPA and WHO gu...
