A text based approach to content based information retrieval for Indian medicinal plants

The usage of plants as foodstuff and also medicine is universal. It is important and yet a difficult task to identify the medicinal plants’ species present in the universe through computers. Development of a machine vision system for medicinal plants is a dire necessity as this tacit knowledge dies with the experts in the field. Hence it is helpful to understand and manage these medicinal plants in the interest of...

Inhibition of the corrosion of mild steel in H2SO4 by 5-amino-1-cyclopropyl-7-[(3R, 5S) 3, 5-dimethylpiperazin-1-YL] -6, 8-difluoro-4-oxo-uinoline-3-carboxylic acid (ACPDQC)

Adsorption and inhibitive efficiencies of ACPDQC on mild steel corrosion have been studied using gasometric and thermometric techniques. ACPDQC is found to be a good inhibitor for the corrosion of mild steel in H2SO4 solution. The inhibition efficiencies of ACPDQC were found to decrease with increase in temperature but increased with increase in the concentration of the extract. Thermodynamic/adsorption...

Kinetic and thermodynamic study of the adsorption of Pb (II) from aqueous solution to the natural and treated bentonite

Lead (Pb) is one of the major environmental pollutants. Adsorption appears to be the most widely used for the removal of heavy metals. The aim of this work is to investigate the adsorption potential of commercial natural bentonite (NB) in the removal of Pb (II) ions from aqueous solution. The effect of different variables, such as, concentration of Pb, mass of NB, pH, time, NB washing and heat treatment and temperature...

Determination of lead, cadmium and mercury in surrounding water and organs of some species of fish from Ikpoba river in Benin city, Nigeria

The mean concentration of some heavy metals (lead, cadmium and mercury) in the muscles and the organs of some common species of fish: Metacembelus Iconnbergii, Clarias lazera, Citarinus citharus, Tilapia zilli and Erpetoichithy were investigated using atomic absorption spectrophotometric method. The mean concentrations of lead in the muscle, kidney and liver were in the ranges of 0.00 – 0.004...
