The Ali-Abad porphyry copper deposit is located in the Central Iranian magmatic belt. As a result of subduction magmatism, Oligo-Miocene leucogranitoid rocks have intruded into conglomerates of lower Cretaceous age. Due ...

The study aimed to investigate the microsporogenesis, tapetum and pollen development in Petunia hybrida Juss.under control and air pollution condition. The connective shows a well-developed placentoid, giving thesporogenous ...

Little is known about Chironomidae in Iran. This article is the second one on chironomid larval identification in running waters of Iran. Samples were collected from five sites in the Golpayegan River, (Isfahan-Iran), ...

In this paper we construct the category of coverings of fundamental generalized Lie group-groupoid associatedwith a connected generalized Lie group. We show that this category is equivalent to the category of coverings of ...

Exposure buildup factors have been calculated by Monte Carlo method for point isotropic gamma ray sources, penetrating a two-layer spherical shield of water surrounded by lead, and the effect of bremsstrahlung radiation ...

In this paper, a new numerical method for solving time-fractional diffusion equations is introduced. For this purpose, finite difference scheme for discretization in time and Chebyshev collocation method is applied. Also, ...

14-Aryl- and 14-alkyl-14-H-dibenzo [a,j]xanthenes are prepared from the reaction of aromatic- and aliphaticaldehydes with β-naphthol in the presence of catalytic amounts of 4-dodecylbenzenesulfonic acid(DBSA) as asurfactant-type ...

A computational method for numerical solution of a nonlinear Volterra and Fredholm integro-differentialequations of fractional order based on Chebyshev cardinal functions is introduced. The Chebyshev cardinaloperational ...

The methanolic extracts, infusions, decoctions and hydrosols of six plants were investigated for their total phenolic contents, antioxidant and antimicrobial activities: Mentha piperita (Peppermint), Thymus vulgaris   ...
