Methyl 3,4,5-trihydroxybenzoate (methyl gallate) was synthesized from 3,4,5-trihydroxybenzoic acid (gallic acid) by reaction with methanol in presence of sulphuric acid. gallate then reacted hydrazine monohydrate to give 3,4,5-trihydroxybenzohydrazide (galloyl hydrazide). The structure methyl and galloyl hydrazide characterized Fourier transforms infrared (FTIR) spectroscopy, mass spectrometry ...

A. D. McCartt, T. Ognibene, G. Bench, K. Turteltaub Lawrence Livermore National Laboratory Purpose The prevalence of carbon in living organisms makes carbon-14 an ideal isotopic tracer for biological studies. In the past decades, carbon-14 has been used in studies of pharmacology, nutrition, carcinogenesis, toxicology, and fundamental biology. For micro-tracer studies, where small, physiologica...

In this work, Concurrent Engineering (CE) approach has been used to determine the most optimum decision on design concept and material of the composite accelerator pedal at conceptual design stage. Comprehensive studies are carried out to prepare the design specifications of composite accelerator pedal. Various design concepts are generated using the Morphological approach. In particular at des...
