The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...

to assess biogeographic affinity of the late cambrian (furongian) and the early ordovician (late tremadocian) faunas of eastern alborz, a multivariate cluster analysis using the pair-group raup-crick similarity index has been applied. the late cambrian fauna of alborz shows clear gondwanan signatures with the closest affinities to the contemporaneous faunas of temperate latitude peri-gondwana (...

iran is a vast land of geographically specific features and the climate is quite different. each year a number of times, short intense rains caused flooding in various parts of the southern coast of the caspian sea and river flood malicious conduct is falling. the rainfall intensity is greater and more destructive floods caused heavy damage. severe flooding during the brutal summer precipitatio...

using global free air gravity and topography data, first we have calculated a bouguer anomaly (ba) map for iranian plateau and then computed the residual isostasy anomaly map under the airy-heiskannen assumption. the term residual is used as to reflect the assumption of local isostatic compensation in contrast to a regional isostatic compensation. the value with which the gravity effect of the ...
