in this study two intelligent systems, based on adaptive neuro-fuzzy inference systems (anfis) and artificial neural networks (anns) of forecasting municipal solid wastes (msw) generation has been proposed. anfis and anns as an intelligent tool compared with together was used to monthly prediction of msw generated in tehran. monthly amount of solid wastes (sw), total monthly precipitation, mont...

sexual behavior in most moths is limited to a precise duration period of either the day or the night. these behaviors as well as the calling behavior are specific. information on reproductive behavior is important in the chemical ecology studies. experiments were conducted to determine the developmental biology, adult time emergence and calling behaviors of three populations of carob moth, ecto...

background:   purpose:   method:   results:   conclusion:

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

this research was aimed to investgate the effect of light quality on micropropagation of pear rootstock oh×f333. first, single nodes explants were cultured in modified ql medium containing ba at four levels (0, 0.5, 1, and 2 mg/l-1) and iaa at three levels (0, 0.1, and 1 mg/l-1) and were evaluated for shoot proliferation. then, plantlets subcultured in modified ql medium containing 1 mg/l-1 ba ...

the effect of gibberellic acid (ga3) spraying on some characteristics of cyclamen flowering trend during the second flowering year was investigated. ga3 sprays were applied in concentrations of 0, 20, 30, 40, and 50 mg/l. the trial was carried out as a randomized complete design of three replications. the total flower count, flower count during the flowering peak, days from spraying to flowerin...

in order to study, the effect of pre-cooling treatment, osmotic potential and water stress on some population of two species of satureja bachtiarica and satureja sahendica was studied by a factorial experiment based on completely randomized design with three replications in laboratory and greenhouse conditions during one year in the gene bank of institute of forests and range lands by the years...

abstract: salicylic acid is a phytohormone with phenolic nature which has been proved its role in increasing plant resistance to biotic and abiotic stress in several studies. this study was performed in order to investigation of interaction between 0, 0.5 and 1.5 mm concentrations of salicylic acid, as a seed pretreatment and different levels of drought stress (100, 75, 50 and 25 percent of fie...
