introduction tectonic of binaloud mountain ranges is controled by thrust faults system and folds related to these faults. parts of this mountain ranges and neyshabour plain is as study area in north eastern iran and between latitudes 36° 11´ 00 to 36° 30´ 00 and longitudes 58° 35´ 00 to 59° 00´ 00. in this paper we first study morphometric indices in this area then analyze drainages and allovia...

introduction water vapor can spread in molecular, unstable and erratic phase and can also transfer by convection and advection process. this transfer happens from the earth and ocean surfaces to the atmosphere in hot air. this type of transfer is considered as the main pattern. in the studies of the atmosphere, one of the prominent factors to be considered is the complexity of water vapor and i...

regional analysis is one of the important methods for estimating the low flow in ungagged regions. investigation of the relations between effective factors of hydrological drought is the most important strategy to contrast and reduction of drought losses. in this study to analyze of low flow, the daily discharge data from 20 gauging stations with 25 years period (1988-2012) in the kashafroud ba...

root colonization by antagonist bacteria has been considered as a prerequisite for a successful biocontrol. for an effective suppression of plant disease, an efficient and fast colonization is necessary to prevent the establishment of pathogen on the root system. colonization of canola root by strain utpf86 were investigated with and without rhizoctonia solani ag-4, under greenhouse conditions....

the behavior of suspended sediment during flood events is not only a function of energy conditions, i.e. sediment is stored at low flow and transported under high flow conditions, but also is related to the variations in sediment supply and sediment depletion. these changes in sediment availability result in so-called hysteresis effects. therefore, hysteresis pattern analysis is of great import...

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...

the catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. in the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products was observed. the 1,3,5-trioxanes were major and aldol condensation compounds were minor products.

the objective of the present study was to optimize awettable powder formulation for twoiranianbtstrains (yd5 and kh4) in order to enhance efficiency and durability as biological agent against lepidopteran and coleopteran pests.mass production of the mentioned strains was done in a batch fermentor based on the peviouselyoptimized economical medium and fermentation conditions, and the final conce...

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...

in this research priority of gorgan’s sub- watershed were done after normalizing the indicators using gis software. the multi-attribute decision-making methods including electre, topsis and saw were used in this study. ahp was applied in order to weighting the indicators in expert choice software. first, priority the sub-watershed were done by electre, topsis and saw using the excel. each metho...
