The article presents the findings on use of foliar treatment with suspensions sapropel, vermicompost, diatomite conventional grinding and in ultrafine form. Fertilizers, ground to smallest particles deionized water under action ultrasound, have a high stimulating effect crop shown better results compared milled fertilizers. yield spring barley Prairia variety non-foliar these fertilizers contri...
A new species of the genus Ectagela Schmidt (Phylinae) from Iran, Ectagela kermanensis sp. nov. is described and illustrated. The type specimens are deposited in the insect collection of the Natural History Museum of University of Guilan, Rasht, Iran.
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...

Diatomite needs to go through the flux-calcination process in order increase its functionality some specific applications such as filter aids. In this study, effects of thenardite, which was used for first time a flux calcination diatomite, and widely soda ash on industrially important physico-chemical properties diatomite were investigated. Samples taken from two deposits Aegean region Turkey ...
Studies on the kinetics of adsorption methylene blue dye (MB) from an aqueous solution a DDT photocatalyst (nanoscale titanium dioxide in anatase phase deposited diatomite) and its components – diatomite D TiO2 are presented. The effect initial concentration pH MB process rate is investigated. kinetic data were processed using two simplified models pseudo-first pseudo-second order. A model intr...
Using published records and original data from recent field work and revision of Iranian material of certain species deposited in the collections of the Natural History Museum Basel, the Zoological Museum Berlin, and Natural History Museum Vienna, a checklist of the freshwater gastropod fauna of Iran was compiled. This checklist contains 73 species from 34 genera and 14 families of freshwater s...
A quick, simple and improved DNA extraction method from polysaccharide rich leaves of Boswellia serrata Roxb. has been developed. Different methods involving use of CTAB and SDS with or without modification were used. A CTAB based extraction method which uses diatomite to remove polysaccharides, such as, gums and resin, proved to be the best. This method allowed recovery of good quality DNA in ...
