In this research, feedforwardANN (Artificial Neural Network) model is developed and validated for predicting the pH at 10 different locations of the distribution system of drinking water of Hyderabad city. The developed model is MLP (Multilayer Perceptron) with back propagation algorithm.The data for the training and testing of the model are collected through an experimental analysis on weekly ...

Hydrogels based on poly(acrylic acid) and gelatin crosslinked with N,N'-methylene bisacrylamide (0.5mol%) and glutaraldehyde (4%), respectively, forming an interpenetrating network were employed as matrices, for studying the loading and release of gentamicin sulphate. The release kinetics of gentamicin sulphate was evaluated in water (pH approximately 5.8), phosphate buffer (pH 7.4) and citrate...

laboratory degradation studies were performed in water at ph 4.0, 7.0 and 9.2 using benthiocarb (saturn 50 ec) formulation at the rates of 1.0 (t1) and 2.0 (t2) î¼g/ml. water samples collected on 0 (2h),3,7,15,30,45,60 and 90 days after treatments were processed for residue analysis of benthiocarb by gc-npd capillary system. in 60 days, dissipation was 92.82-93.81 % at ph 4.0, 89.12-90.63 % at ...

A few studies have investigated the interaction between copper toxicity and water pH in fishes, but little is known about the effects of acidic pH on the toxicity of copper nanoparticles (Cu-NPs). This study aimed to describe the sub-lethal toxic effects of Cu-NPs compared to CuSO4 at neutral and acidic water pH values in juvenile rainbow trout. Fish were exposed in triplicate (3 tanks/treatmen...

Small blocks of the kidney and other organs were taken from adult rats, which had been perfused arterially with Ringer solution and with 0.1M phosphate buffer containing 2% glutaraldehyde (pH 7.4). The blocks were further fixed for 28hrs in 2% glutaraldehyde in a phosphate buffer (pH 7.4). The fixed spcimens were soaked for 16hrs in distilled water containing 2% arginine hydrochloride, 2% glyci...

One way to determine the pH at the air/water interface with a confocal fluorescence microscope has been proposed. The relation between the pH at the air/water interface and that in a bulk solution has been formulated in connection with the adsorption equilibrium and the dissociation equilibrium of the dye adsorbed. Rhodamine B (RhB) is used as a surface-active fluorescent pH probe. The correcte...
