introduction cultivation of medicinal plants in agricultural ecosystems plays an important role in the diversification and sustainability of these systems (rezaei-chiyaneh & dabbagh mohammadi nassab, 2014). therefore, the application of ecological principles such as multi-ship system seems essential in the production of these plants. zarifpour et al. (2014) in intercropping arrangements of cumi...

a comparison of the photoefficiency of ni(ii) and nis incorporated into zeolite p towards photodecolorization of eriochrome black t dye solution was investigated in a photocatalytic reactor using uv lamp as a light source. the effect of various experimental variables on the decolorization performance of the process was evaluated by examining catalyst dosage, temperature, initial dye concentrati...

black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

nicr2o4 normal spinel nanostructures were prepared via hydrothermal treatment at 180 °c for 12 h in the presence of cetyltrimethylammonium bromide (ctab), sodium dodecyl sulphate (sds) and poly vinylpyrrolidone-25000 (pvp-25000) as capping agents and subsequent calcination process at 500 °c for 3 h . in this method, [ni(en)2(h2o)2](no3)2 and [cr(en)3]cl3.3h2o used as precursors and not utilized...

classical explicit finite difference schemes are unsuitable for the solution of the famous black-scholes partial differential equation, since they impose severe restrictions on the time step. furthermore, they may produce spurious oscillations in the solution. we propose a new scheme that is free of spurious oscillations and guarantees the positivity of the solution for arbitrary stepsizes. the...

during a survey in 2015, three dark-winged fungus gnat species, bradysia odoriphaga yang & zhang, 1985, bradysia trivittata staeger, 1840and scatopsciara atomariazetterstedt, 1851 were identified and recorded here from iran for the first time. the genus scatopsciara edwards, 1927 is newly recorded from iran as well. the identification of specimens were confirmed by dr kai heller (germany). the ...
