Monitoring the Effects of Inclusions in Model Glass Systems Using Acousto-Ultrasonic Techniques
The feasibility of employing acousto-ultrasonic techniques for monitoring the effects of inclusions in ceramics has been studied using model glass matrix composites. Two brittle inclusions, namely alumina and silicon ...
Spectral Analysis of Acousto-Ultrasonic Waves for Defect Sizing
A study of the feasibility of employing acousto-ultrasonic (AU) testing to size defects has been carried out using a model system consisting of a single defect in a glass matrix. A through-transmission mode was used for ...
Indirect Ppectrometric determination of phosphate
This paper reports the development of an alternative quantitative analytical procedure for the determination of phosphate by an indirect method. It involves the precipitation of magnesium ammonium phosphate, which is ...
Glutathione S-Transferases: α-Naphthyl Acetate Activity and Possible Role in Insecticide Resistance
Rat liver and house fly, Musca domestica L., glutathione S-transferases were purified by affinity chromatography and chromatofocusing. The specific activity with α-naphthyl acetate (a substrate, for general esterase activity) ...
