Water and nitrogen supply are the two primary factors limiting productivity of wheat (Triticum aestivum L.).

Our results indicated that drought stress greatly reduced the ne...
A cross-sectional study investigated risk factors associated with choices to drink bottled water and tap water in rural Saskatchewan. Of 7,500 anonymous postal questionnaires mailed out, 2,065 responses were analyzed using generalized linear mixed models.

Lakes are very interesting sedimentary environments for the study of ancient climate, changes in sedimentary environments and lake level changes. Lake Zeribar is situated in the Zagros Mountains, Kurdistan, Iran. The main purpose of this research is to examine grain size sediments, geochronology and clay mineralogy accumulated in Zeribar Lake in order to check the water level fluctuations, clim...
Introduction Iran is seriously suffering from economic and social drought. Theoretically, this problem can be resolved by rebalancing the supply and demand of water through the development of supplied water resources and implementing serious water demand reduction programs. However, the current structure of Iranchr(chr(chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))39chr(chr(chr('39...
