although the persian sturgeon, acipenser persicus , is a commercially valuable sturgeon species of the caspian sea, but there are only few reports about its parasite fauna in the southern part of the caspian sea. in this study, a total of 209 individuals of persian sturgeon were collected from two regions in the southwestern of caspian sea (guilan province, iran) from march 2009 to may 2011. af...

In the present paper for a large family of topological semigroups, namely foundation semigroups, for which topological groups and discrete semigroups are elementary examples, it is shown that ?(S) is the dual of a function algebra.

A new Cercospora species, namely, C. neriicola Ershad on Nerium oleandercollected in Iran was described and illustrated. The new species was compared with C. nerii-indici, the other species on Nerium.

in this paper we introduce and study an algebraic structure, namely grouplike. a grouplike is something between semigroup and group and its axioms are generalizations of the four group axioms. every grouplike is a semigroup containing the minimum ideal that is also a maximal subgroup (but the converse is not valid). the first idea of grouplikes comes from b-parts and $b$-addition of real number...

Three new records of Tanacetum L., namely, T. punctatum and T. zahlbruckneri from Azerbaidjan and T. vulgare from Mazandaran Provinces are reported for the first time from Iran. Illustrations and distribution map are also presented for each species.

salt stress negatively impacts crops yield throughout the world. nine varieties of potato (solanum tuberosum l.) were screened for salt stress tolerance by measuring in-vitro growth of the aerial plant parts, as well as roots. salt stress was evaluated by adding 25, 50, 75, 100, 125, 150 and 200 mm of nacl to murashige- skoog (ms) medium and compared to ms medium without nacl. plant length and ...

despite the consensus of jurists (fokaha) in safe custody of property (haraz) as one of the punishable conditions when the theft happens, some jurists made an exception in bird case. it means that stealing the bird would not subject to punishment namely cut off the thief's hand, even if the bird was in safe custody.  many of  fokaha, however,  believe that if the bird is in safe custody, t...

Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...
