The impact of industrial effluent on the Oruku River in southwestern region of Nigeria was investigated. Surface water, sediment, ground water and industrial effluent samples were obtained bimonthly for 18 months (March 2005 to September 2006). Effluent characteristics varied widely with averages of DO (4.25±1.3 mg/L), BOD (27.5±43 mg/L), Pb (0.41±0.26 mg/L), Cr (0.26±0.48 mg/L) and Ni (0.19±0....
In recent years, Aquaculture has an important role to play in The production of animal proteins, employment, and poverty reduction, especially in rural areas. Water supply as a limiting factor in developing countries. Therefore, Multipurpose use of water resources, including, Water use at integrated aquaculture-agriculture farms is a Strategies for Sustainable Development in the world. The aims...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
there are several factors influencing the water quality based on its usage. the quality of drinking water is of the vital concern for human health and life. an essential attempt has to be done to develop a water quality index (wqi) corresponding with different conditions and characteristics of the relevant river or water body such as geographical, hydrological, discharge rate and pollution sou...
extended abstract abstract pressure management is an effective method for water demand management. for evaluation of the effects of pressure changes on leakage level of water networks, the favad equation is usually used. however, in this equation, exponent of pressure parameter (n) needs to be determined. for estimation of n, either some information about the leak opening is necessary or networ...
There are some unique geomorphic phenomenon in Iran that Clutes and Chahnimes can be considered among them. There are two theories published in books and articles about the development Chahnimes in Sistan-Baluchistan province, one of which relates its development to tectonic activities and the other attributes it to the process of water and wind. And there is still a lack of documented studies ...
The safety and security of water supplies have come under reassessment in the United States in recent years. Issues ranging from public safety and health, ecological, and national security are under consideration. The terrorist attacks on the United States on September 11, 2001 and the subsequent delivery of Anthrax-contaminated letters through the mail raised concerns about protecting U.S. cit...
Previous studies have shown that morphine administration could inhibit neural tube development in rat embryos and produce behavioral defects in human and animals. In the present study, the effects of maternal morphine consumption on embryonic neural plate development in Wistar rats were investigated. Methods: Twenty-four female Wistar rats (250-300 g) were crossed with males. After pregnancy...

BACKGROUND/AIMS Water channels, also named aquaporins (AQPs), play crucial roles in cellular water homeostasis. METHODS RT-PCR indicated the mRNA expression of AQPs 1-5, 7, 9, and 11-12, but not AQPs 0, 6, 8, and 10 in the 2∼8-cell stage human embryos. AQP3 and AQP7 were further analyzed for their mRNA expression and protein expression in the oocyte, zygote, 2-cell embryo, 4-cell embryo, 8-ce...
