Garden and Persian carpets of among the oldest phenomena in the course of history. There are some points which indicate that garden and carpet have been closely connected. Chaharbagh structures were important works of ancient pre-Islamic Iran, at Achaemenid and Sassanid periods and Ilkhanid era, especially in the Timurid and Safavid era. Like Chaharbagh style, Chaharbagh or Golestan motif...

Historic gardens of Shiraz were considered among key elements of the city up to the Pahlavi and contemporary era. It seems that the formation of the historic core of the city and its development in different periods involved gardens, both regarding the structural relationship between the two, and also in the use of the garden and its elements in the body of the city. On the other hand, the gard...

for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...

in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...

for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.

vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
