Sri Venkateswara College of Engineering an engineering institute in Tamil Nadu, located at Pennalur, Sriperumbudur near Chennai.SVCE was founded by the Sri Venkateswara Educational and Health Trust in 1985. The Trust was founded on August 1, 1984 at the behest of Sri Jayendra Saraswathi Swamigal. The college, established in the city of Chennai by the Southern Petrochemical Industries Corporation group, a prominent petro-chemical corporation in India, is said to be among the top engineering colleges in Tamil Nadu, and a Tier-I institution among self-financing colleges.SVCE's founding objective was to implement a programme of education in engineering and allied science, to promote research, disseminate knowledge and to foster the cooperation and exchange of ideas between the academic community and industrial organizations and to develop entrepreneurship skills among students.

The Fourier transform infrared (FT-IR) and FT-Raman of 9-[(2-hydroxyethoxy) methyl] guanine (9-2HEMG) have been recorded in the regions 4000-100 and 4000-400 cm-1, respectively. A complete assignment and analysis of the fundamental vibrational modes of the molecule were carried out. The observed fundamental modes have been compared with the harmonic vibrational frequencies computed using DFT (B3LYP) method by employing 6-31G(d,p) and 3-21G basis sets. The vibrational studies were interpreted in terms of potential energy distribution. The first order hyperpolarizability (β0) and related properties (α, μ and Δα) of this molecular system are calculated using B3LYP/6-31G(d,p) method based on the finite-field approach. Stability of the molecule arising from hyperconjugative interactions and charge delocalization has been analyzed using natural bond orbital (NBO) analysis. The results show that electron density (ED) in the σ* and π* antibonding orbitals and second-order delocalization energies (E(2)) confirm the occurrence of intramolecular charge transfer (ICT) within the molecule. UV-vis spectrum of the compound has been recorded and electronic properties such as excitation energies, oscillator strength and wavelength are calculated by TD-DFT and CIS methods using B3LYP/6-31G (d,p) basis set. Molecular electrostatic potential (MEP) and HOMO-LUMO energy levels are also constructed. The thermodynamic properties of the title compound have been calculated at different temperatures and the results reveal that the standard heat capacities (Cp,m), standard entropies (Sm) and standard enthalpy changes (Hm) increase with rise in temperature. © 2012 Elsevier Masson SAS.

Indeed, the engine industries have seen a tremendous growth in the research and development of new-age technologies over the past ten years or so. Even though a huge database is now available on present-day engine technologies, a skillful presentation of those data is a demanding task. At this count, an endeavor has been made here to brief the pros and cons of present-day engine technologies in an elusive manner. In a nut-shell, this article provides an extensive review of the primary principles that preside over the internal combustion engines design and operation, as well as a simplifying framework of new-age engine technologies has been organized and summarized in an elegant way to contribute to this pragmatic field. © 2014 Elsevier Ltd.

The electronic parameters of tacrine were evaluated by quantum chemical method to assess its corrosion inhibition potential. Further, it was confirmed by chemical and electrochemical studies on steel in 1.0M HCl and 0.5M H 2SO 4. It was found that tacrine performed better than the quantum prediction which is attributed to the planarity of the molecule. Also, tacrine is found to be more efficient in 1.0M HCl than in 0.5M H 2SO 4, which according to potential of zero charge study, is due to acid anions Cl - and SO42- Tacrine pursued Langmuir adsorption isotherm. © 2012 Elsevier Ltd.

Indeed, the development of alternate fuels for use in internal combustion engines has traditionally been an evolutionary process in which fuel-related problems are met and critical fuel properties are identified and their specific limits defined to resolve the problem. In this regard, this research outlines a vision of lemongrass oil combustion characteristics. In a nut-shell, the combustion phenomena of lemongrass oil were investigated at engine speed of 1500 rpm and compression ratio of 17.5 in a 4-stroke cycle compression ignition engine. Furthermore, the engine tests were conducted with partial premixed charge compression ignition-direct injection (PCCI-DI) dual fuel system to profoundly address the combustion phenomena. Analysis of cylinder pressure data and heat-release analysis of neat and premixed lemongrass oil were demonstrated in-detail and compared with conventional diesel. The experimental outcomes disclosed that successful ignition and energy release trends can be obtained from a compression ignition engine fueled with lemongrass oil. © 2015 Faculty of Engineering, Alexandria University.

The Fourier transform infrared (FT-IR) and FT-Raman of 4-[(4-aminobenzene) sulfonyl] aniline have been recorded and analyzed. The equilibrium geometry, harmonic vibrational frequencies have been investigated with the help of HF and DFT methods with 6-31G(d,p) as basis set. A detailed interpretation of the vibrational spectra of this compound has been made on the basis of the calculated potential energy distribution (PED). The 1H and 13C nuclear magnetic resonance (NMR) chemical shifts of the molecule were calculated by GIAO method. Stability of the molecule arising from hyper conjugative interactions, charge delocalization has been analyzed using natural bond orbital (NBO) analysis. The linear polarizability (α) and the first order hyperpolarizability (β) values of the investigated molecule have been computed using DFT quantum mechanical calculations. UV-vis spectrum of the compound was recorded and electronic properties, such as HOMO and LUMO energies were also performed. Finally the calculations results were applied to simulated infrared and Raman spectra of the title compound which show good agreement with observed spectra. © 2012 Elsevier B.V. All rights reserved.
