Research ArticleOpen accessIn the abstractCorrosion of Copper Metal in Presence of Binary MixturesMedhat A. Shaker, Hanaa H. Abdel-RahmanThe rates of copper corrosion were determined in presence and in absence of different compositions of water-ethanol, -ethylene glycol, -glycerol, -dimethyl sulfoxide (DMSO) and -dioxane binary mixtures. The rates of corrosion were found to decrease by increasing the concentration of solvents. The percent inhibition range from 10.9 to 78.2% depends on the nature of solvent and its concentration. The calculated … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 8,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Crude Polyphenol Oxidase Activity in Buckwheat SproutsYuedong Song, Yangfang Zhang, Yilin Wang et al.Buckwheat sprouts can not only effectively reduce the trypsin inhibitor in buckwheat grain, but also improve the content of bioactive ingredients such as flavonoids and other effective components. However, Polyphenol Oxidase (PPO) in buckwheat sprouts causes browning of food, which limits the application of buckwheat sprouts in food. In addressing this problem, studying the characteristics of PPO in buckwheat sprouts … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 25 Jun 2021 · 6,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on Salivary Glands α-amylase In Wheat Bug Eurygaster maura (Hemiptera: Scutelleridae)Mohammad Mehrabadi, Ali R. Bandaniα-amylase activity in the salivary glands of Eurygaster maura was determined by biochemical experiments. Some of adult insect was collected and their salivary glands isolated and characterized. Enzyme samples from salivary glands of adults were prepared by the method of Cohen with slight modifications. α-Amylase activity was assayed based on Bernfeld method by the dinitrosalicylic acid (DNS) procedure. The activity … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,643 accessesView PDFCite
