water is a main resource in sustainable development planning where the management of quality and quantity of these resources play an important role in public health and social welfare. on the other hand, due to social, economic and environmental values of this vital resource, water resource management is considered as a very important task. the long term water strategies are not only a useful g...

â  â  background esophageal squamous cell carcinoma (escc) is usually detected in advanced stages resulting in a very poor prognosis. early diagnoâ­sis needs identification of clinically relevant precancerous lesions which could become the target of screening and early treatment. our aim was to check whether esophagitis could serve as a relevant histological precursor of escc in northern iran. ...

some biological characteristics of broodstock and juvenile kutum, rutilus kutum. were investigated using data collected from the estuaries of tajen and shirood rivers (tr and sr) (southern caspian sea basin) as well as from the caspian sea in 2012. the results showed higher condition factors (cf) in the male broodstocks kutum than those estimated in the female broodstock of both tr and sr. the ...

introduction: in spite of improving the water productivity due to development in water infrastructure systems, population increasing causing the water withdrawal is triple in the last fifty years. in this situation competition on water consumption especially in the agricultural sector which is the biggest consumer in the world and also in iran is a severe problem. water allocation has been asse...

A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...

OBJECTIVES To examine nonylphenol (NP) and 4-t-octylphenol (OP) concentrations and general water quality indicators along a river in the greater Tokyo area and to specify the distribution and origin of alkylphenols. METHODS Water was sampled from the Edogawa River, a main river in the greater Tokyo area, which is a source of public drinking water; and the Sakagawa River system, a tributary of...

Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...
