Background: Cucumber mosaic virus (CMV) from the Bromoviridae family, is one of the most widespread plant viruses in the world. Objectives: In the present study tomato fields in Guilan, Isfahan, Khorasan Razavi, Khuzestan and Tehran provinces were surveyed to determine the presence of CMV subgroups during 2011-2012. Materials and Methods: Out of 305 symptomatic leaf samples ...

The possible lower symmetries (subgroups) of the A2BX4 structure (space-group symmetry D4& ) due to rigid octahedral tiltings at phase transitions are investigated. The method for obtaining subgroups determined by reducible representations (i.e., coupled order parameters) is described. This method depends upon subgroup information for irreducible representations (i.e., single uncoupled order pa...

Cancer is considered as a challenging deathly disease and discovering or synthesis of new cytotoxic agents is a worldwide attempt. In this study, a group of recently synthesized chalcones, with the structure of 1,3-diarylprop-2-en-1-one having differesnt COX-1 and/or COX-2 selectivities, have been examined on human hepatocarcinoma (HepG2), lung carcinoma (A549), and breast adenocarcinoma (MCF-7...

We investigate the minimum distance of the error correcting code formed by the homomorphisms between two finite groups G and H. We prove some general structural results on how the distance behaves with respect to natural group operations, such as passing to subgroups and quotients, and taking products. Our main result is a general formula for the distance when G is solvable or H is nilpotent, i...

We study the Newman--Unti (NU) group from viewpoint of infinite-dimensional geometry. The NU is a topological in natural coarse topology, but it does not become manifold and hence Lie this topology. To obtain structure we consider finer Whitney-type This turns unit component into an group. then theoretic properties Surprisingly, operations full discontinuous, whence support structure. contains ...
