Gandhigram Rural Institute, founded in 1956, is situated near Dindigul in Tamil Nadu, India. Dr.T.S.Soundaram and Dr.G.Ramachandran developed the institute. The Gandhigram Rural Institute was founded there in 1956 to carry on Mahatma Gandhi’s ‘Nai Talim’ system of education. In 1976 it was declared as Deemed University, by University Grants Commission , New Delhi, Under Section 3 of UGC Act 1956. It is fully funded by UGC. In 2006 it was renamed Gandhigram Rural Institute as per the guidelines of UGC. Again, as per UGC guidelines, the name of the institute has been changed to Gandhigram Rural Institute in 2009.With devotion to Mahatma Gandhi’s revolutionary concept of ‘Nai Talim’ system of education, Gandhigram Rural Institute has developed academic programmes in Rural Development, Rural Economics and Extension Education, Rural Oriented science, Cooperation, Development Administration, Rural Sociology, English and Communicative Studies, and, Tamil and Indian Languages.The work of the institute invited national attention and the Government of India , on the recommendation of the University Grants Commission, conferred the status of a Deemed University on the institute under Section of the UGC Act of 1956, on 3 August 1976.The institute has developed into a major educational complex, comprising seven faculties, offering in 50 programmes. It awards Doctoral, Master’s and Bachelor’s Degrees, Diplomas and Certificates through its seven academic faculties: Rural Development, Rural Social science, Rural Oriented science, English and Foreign Languages, Tamil, Indian Languages and Rural Arts, Rural Health and Sanitation, and, Agriculture and Animal Husbandry. It has 3000 students and 150 teaching and 250 non-teaching staff.The institute was accredited with Five Star status by NAAC, in February 2002.It was re-accredited with A grade in 2010. Wikipedia.

In this paper, we present a method for the numerical solution of Love's equation in a particular physical system. The resolution protocol is based on the Boubaker Polynomials Expansion Scheme (BPES), followed by array analyses. The obtained results are compared with some recently published ones. The accuracy and the asymptotic behaviors of the solutions are discussed. © 2010 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.

A new biocomposite was prepared by incorporating inorganic ion exchanger namely zirconium(IV) tungstophosphate (ZrWP) into the chitosan biopolymeric matrix. The sorption behaviour of fluoride from aqueous solutions by this ZrWP/chitosan (ZrWPCs) composite has been investigated by batch technique. The fluoride sorption was studied as a function of contact time, pH, initial fluoride concentration, competing co-ions and temperature. The defluoridation capacity (DC) of the adsorbent was found to be 2025 mgF- kg-1. The composite was characterized using FTIR and SEM with EDAX analysis. The equilibrium sorption data were fitted to Freundlich and Langmuir isotherms. The kinetics of sorption was found to follow pseudo-second-order and intraparticle diffusion models. The values of thermodynamic parameters indicate the nature of sorption is spontaneous and endothermic. The biocomposite was successfully used for the removal of fluoride from the field water taken in a nearby fluoride endemic village. © 2009 Elsevier B.V. All rights reserved.

Alumina possesses an appreciable defluoridation capacity (DC) of 1566mgF-/kg. In order to improve its DC, it is aimed to prepare alumina polymeric composites using the chitosan. Alumina/chitosan (AlCs) composite was prepared by incorporating alumina particles in the chitosan polymeric matrix, which can be made into any desired form viz., beads, candles and membranes. AlCs composite displayed a maximum DC of 3809mgF-/kg than the alumina and chitosan (52mgF-/kg). The fluoride removal studies were carried out in batch mode to optimize the equilibrium parameters viz., contact time, pH, co-anions and temperature. The equilibrium data was fitted with Freundlich and Langmuir isotherms to find the best fit for the sorption process. The calculated values of thermodynamic parameters indicate the nature of sorption. The surface characterisation of the sorbent was performed by FTIR, AFM and SEM with EDAX analysis. A possible mechanism of fluoride sorption by AlCs composite has been proposed. Suitability of AlCs composite at field conditions was tested with a field sample taken from a nearby fluoride-endemic village. This work provides a potential platform for the development of defluoridation technology. © 2010 Elsevier B.V.

Vanadium pentoxide (V 2O 5) has attracted attention for supercapcitor applications because of its extensive multifunctional properties. In the present study, V 2O 5 nanoporous network was synthesized via simple capping-agent-assisted precipitation technique and it is further annealed at different temperatures. The effect of annealing temperature on the morphology, electrochemical and structural properties, and stability upon oxidation-reduction cycling has been analyzed for supercapacitor application. We achieved highest specific capacitance of 316 F g -1 for interconnected V 2O 5 nanoporous network. This interconnected nanoporous network creates facile nanochannels for ion diffusion and facilitates the easy accessibility of ions. Moreover, after six hundred consecutive cycling processes the specific capacitance has changed only by 24%. A simple cost-effective preparation technique of V 2O 5 nanoporous network with excellent capacitive behavior, energy density, and stability encourages its possible commercial exploitation for the development of high-performance supercapacitors. © 2012 American Chemical Society.

This paper describes the simultaneous determination of ascorbic acid (AA), dopamine (DA), uric acid (UA) and xanthine (XN) using an ultrathin electropolymerized film of 2-amino-1,3,4-thiadiazole (p-ATD) modified glassy carbon (GC) electrode in 0.20 M phosphate buffer solution (pH 5.0). Bare GC electrode failed to resolve the voltammetric signals of AA, DA, UA and XN in a mixture. On the other hand, the p-ATD modified electrode separated the voltammetric signals of AA, DA, UA and XN with potential differences of 110, 152 and 392 mV between AA-DA, DA-UA and UA-XN, respectively and also enhanced their oxidation peak currents. The modified electrode could sense 5 μM DA and 10 μM each UA and XN even in the presence of 200 μM AA. The oxidation currents were increased from 30 to 300 μM for AA, 5 to 50 μM for DA and 10 to 100 μM for each UA and XN, and the lowest detection limit was found to be 2.01, 0.33, 0.19 and 0.59 μM for AA, DA, UA and XN, respectively (S/N = 3). The practical application of the present modified electrode was demonstrated by the determination of AA, UA and XN in human urine samples. © 2009 Elsevier B.V. All rights reserved.
