decreasing water resources has made optimum water allocation in agriculture essential. planning optimum irrigation and crop production function considering accessible water and growing stage is an efficient approach to increase water productivity. studies have applied this approach to maximize crop production using the fao crop production method introduced in 1979. however, the fao introduced a...

relations between the third world countries in different parts of asia and africa during the 19th and 20th centuries, to a great extent, were influenced by the presence and policies of colonial powers. thus, for a better understanding of roots of disputes and issues existing between these countries concerning frontiers, disputed islands, political and prejudicial tensions, we need to study past...

In this study, the zonality method has been used to separate geochemical anomalies and calculate erosional levels in regional scale for porphyry-Cu deposit, Abrisham-Rud (Semnan province, East of Iran). maps multiplicative haloes, co-existence both supra-ore elements sub-ore local maxima implied blind mineralization northwest study area. Moreover, considering calculated indices two previously p...

in order to improve irrigation water productivity (wp) at rice production, a field experiment was conducted at shahid fozveh research station (esfahan region) during 2001-2003. experiment was arranged in a split plot design (rcbd) with three replications. the treatments were: three levels of irrigation managements including i1: permanent flooding under 3.5cm water during growth period, i2:perma...
