This investigation was undertaken to determine the relative effects of recommended land spraying while drilling (LWD) loading rate application for a source of water-based drilling waste material on selected soil properties and phytotoxicity. Drilling waste material was obtained from a well where a nitrate gypsum water based product was used to formulate the drilling fluid. The fluid and associa...

1. Water requirements, water balance components and dependence on exogenous water were estimated in four species of sympatric rodents inhabiting a Chilean semi-arid region. 2. A significant increase in free water drinking was observed in all rodents when the diet composition was changed from 14 to 20% protein. 3. Under water balance conditions the cricetid species (Phyllotis darwini, Oryzomys l...

An experiment was conducted in order to evaluate the effects of Se spraying on yield and growth indices of wheat under drought stress condition, in agriculture and natural resource research center of Tehran province in 2011-12. A split plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments (normal irrigation, non-irriga...

Carcinogenic and systemic health effects of arsenic exposure in drinking water are well documented. This study estimated the risk associated with chronic consumption of water with high concentrations of arsenic in children and adults living in six Andean locations, in Chile. Concentrations of arsenic in the drinking water were analyzed between 2014 and 2017 based on health authority reports and...

the major purpose of the present investigation was to study the effects of different concentrations of residual chlorine on serum iron related parameters in rats. feeding male rats with water containing 80 ppm of residual chlorine daily for 5 days reduced serum levels of ceruloplasmin, copper, iron and hemoglobin by approximately 27%,23%,6% and 4%, respectively. higher reductions in serum cerul...

+ The water dispenser should be constreucted of food grade materials and be easily cleanable. + The spigot should be of a gravity flow design to prevent contamination during use. + The dispensers should be cleaned and sanitized at least once every 24 hours. Use wash-rinse-sanitize methond for sanitizing dispenser, the compartments of the sink should be of sufficient size to allow immersion of t...
