this paper proposes a method for the prediction of pore size values in hydrocarbon reservoirs using 3d seismic data. to this end, an actual carbonate oil field in the south-western part ofiranwas selected. taking real geological conditions into account, different models of reservoir were constructed for a range of viable pore size values.  seismic surveying was performed next on these models. f...

background: phenol, as a pure substance, is used in many fields because of its disinfectant, germicidal, local anesthetic, and peptizing properties. aqueous solutions of phenol are produced as waste in industries and discharged into the environment. therefore, elevated concentrations of phenol may be found in air or water because of industrial discharge or the use of phenolic products. method: ...

we studied the hepatotoxic effects of a deltamethrin containing formulation (decis®) on developing em-bryo of gallus domesticus. fertilized eggs were immersed in three different concentrations of deltamethrin (12.5, 25 and 50 mg/l) for 60 min at 37 ˚c prior to incubation (ed 0) and on the 4th day of incubation (ed 4) and incubated till embryonic day (ed) 16. exposure to 50 mg/l of deltamethrin ...

in the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. then the pigmented samples were scanned, and the values of rgb of images were calculated. the artificial neural network (ann) method used to make relation between rgb va...

modern hydrometallurgical techniques have been adopted to produce high-purity gold. many extractants were used for the extraction of gold from various synthetic solutions from which dibutyl carbitol (dbc) had a unique superiority. kinetics of process was studied in this paper and the influence of several parameters such as stirring speed, agitation time, impeller type, interfacial area, [aucl4]...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...
