This section contains a review of physical fundamentals and results of practical implementation of methods of nondestructive testing (NDT) and evaluation. It also presents relevant information on magnetic, electrical, eddy current, HF electromagnetic, infrared, optical, acoustic, radiographic, penetrant and other (such as vibration, leakage testing and integrated) methods of NDT and evaluation ...

The results of functional analyses suggested that the destructive behavior of two individuals was sensitive to escape and attention as reinforcement. In an instructional context, we evaluated the effects of reinforcing compliance with functional reinforcers when destructive behavior produced a break. For one participant we also evaluated the effects of reinforcing compliance with functional rei...

The corrosion inhibiting properties of the new furan derivative 5-(furan-2-ylmethylsulfonyl-4-phenyl-2, 4-dihydro [1,2,4] triazole-3-thione in acidic solution (1.0 M HCl) were explored utilizing electrochemical, surface morphology (AFM), and quantum chemical calculations approaches. novel shows with an inhibitory efficiency value 99.4 percent at 150 ppm, carbon steel medium is effectively inhib...

The isothermal adsorption of nicotine from an aqueous solution onto zeolite type USY at temperature range from 298 to 322 K was investigated. It was found that the adsorption isotherms can be described by the Freundlich adsorption isotherm. The density distribution function of adsorption centers has an exponential form and the adsorption isotherms can be fitted by the Freundlich isotherm. The c...

conclusions it was shown that the removal efficiency of nitrate was directly proportional to the amount of chaff, temperature, and contact time but inversely to the ph. this study showed that nitrate removal by chaff is a promising technique. results the result of this study revealed that chaff as an absorbent could remove nitrate from solutions, and the efficiency of adsorption increased as co...

background: as fluoride concentration in drinking water is one of the effective parameters in human health, finding the ways to remove excess amount of fluoride is very important in water supply projects. this study aimed to evaluate mendon bauxite mine in the removal of fluoride from drinking water. methods: this experimental study was conducted from may to october 2013 on synthetic and actual...

Grand-canonical Monte Carlo simulations and adsorption experiments are conducted to understand the adsorption of CO2 onto bundles of 3D aligned double-walled carbon-nanotubes of diameter 5 nm at 303 K. The simulation of partial adsorption isotherms, i.e., only inner tube volume, only interstices between tubes, and unrestricted, allows a breakdown of the experimental adsorption isotherms into co...

in this study, the batch equilibrium method was used to conduct metribuzin adsorption/desorption experiments with eight soils from different regions of iran. the results indicated that the organic carbon (oc) content, clay content, cation exchange capacity (cec), and ph had a combined effect on the metribuzin adsorption on soil. under the experimental conditions, the adsorption amount of metrib...
