in the present  paper electrical conductivity (ec) of colloidal gas aphron (cga) suspensions was measured for anionic and cationic surfactants (sodium dodecyl sulfate (sds) and tetradecyl trimethyl ammonium bromide (ttab)). experiments were made for different concentrations of sds (6, 8.1, 10 mm) and ttab (2, 3.51, 5 mm). cga drainage behavior was observed and measured using 1 liter measuring c...

In the present  paper Electrical Conductivity (EC) of Colloidal Gas Aphron (CGA) suspensions was measured for anionic and cationic surfactants (Sodium Dodecyl Sulfate (SDS) and Tetradecyl Trimethyl Ammonium Bromide (TTAB)). Experiments were made for different concentrations of SDS (6, 8.1, 10 mM) and TTAB (2, 3.51, 5 mM). CGA drainage behavior was observed and measured using 1 liter measuri...

background: phytoremediation is one of the methods used to remove contaminants and while being simple, cheap and efficient, does not cause environmental deterioration. the aims of this study were phytoremediation of soil contaminated by cd, the simultaneous survey of the influence of different electrical conductivity values, and comparison of two soil amendments including sludge and municipal c...

Among different doses of gamma rays, 1.5 kR induced 71.84% callus in Basrnati rice in amodified MS medium and 2% redifferentiation under anon-saline environment, 20% callusing response with 7.5%,2.8% and 2.5% redifferentiation was induced by 2.0 kR at electrical conductivity (EC) of 4,s and 6 dS.m of NaCl respectively, in regeneration medium. A non-irradiated non-saline environment reveale...

Layers of ethylene carbonate (EC) modified CuI/PVA polymer composites were prepared by growth of CuI nano-particles in an aqueous solution of PVA followed by casting at room temperature. The structural, thermal, optical, electrical and di-electrical characterization of polymer composites was investigated using different techniques. These investigations confirm the growth of CuI nano-particles a...

ground water samples from different upazilas of sunamganj district have been analyzed for drinking and irrigation purposes. correlation coefficients among different parameters were determined. an attempt has been made to develop linear regression equations to predict the concentration of water quality constituents having significant correlation coefficients with electrical conductivity (ec). ca...

soil salinity is one of the important factors which can influence the growth anddistribution of plant species. saline and alkaline rangelands of golestan province, iran withlow-deep underground water level are considered as a halophyte plant species growing area.attempts have been made to determine soil salinity and its relationship with frankenia hirsutal. in order to determine the electrical ...

Electrical conductivity (EC) of milk is an indicator of mastitis, and could, if it shows genetic variation and is genetically correlated to mastitis, be used in a breeding program where selection for reduced mastitis resistance is included. In this study, daily measurements of EC and mastitis were analyzed with a bivariate model. For EC, the estimated heritability was high (0.22 to 0.39), while...

Capacitance and resistivity sensors can be used to continuously monitor soil volumetric water content (θ) and pore-water electrical conductivity (EC(p)) with non-destructive methods. However, dielectric readings of capacitance sensors operating at low frequencies are normally biased by high soil electrical conductivity. A procedure to calibrate capacitance-resistance probes in saline conditions...
