1. The Relation of English Language with Science, Technology, and Mathematics: A Critical Study
Author : K. P. Singh
Keyword : EST, STM, ESP, Language, Science, Technology, Mathematics and Engineering

Volume: 7,Issue:1,PP: 1 - 6,Year: (2015)
The present study focuses on importance of language proficiency in the learning of science, technology and mathematics (STM) with attention given to the review of research studies on language and STM within the context of the choice of the language for instruction to the engineering students. The obvious bias on the continual use of the English Language as a medium of instruction in STM at the under graduate level is evident. The discussion is supported by the various studies in which students’ performance in English Language, and in each of mathematics, science and technical subjects in India. The findings revealed significant positive correlation between English Language and the STM subjects. Mathematics and science had the strongest relationship with English Language. English Language should continually be used as a medium of instruction in STM classes at the engineering level. In India English language has been developed as a linguafranca among her numerous indigenous languages to serve as a medium of instruction in STM classes. Students in STM classes, as well as other academic areas, advance their scientific literacy when they develop a critical awareness of the special linguistic conventions that govern their specific fields of study. An awareness of language allows them to develop strategies for accessing content in the texts they read and produce acceptable content in discipline-specific ways in the texts they write.
2. Electrolytic Study of Pyrogallol in Methanol, Ethanol and n-Propanol at Different Temperatures (303K, 308K and 313K)
Author : Seema Shukla, Babita Bhardwaj & S. S. Yadav
Keyword : pyrogallol, Ultrasonic velocity, density and viscosity

For the study of electrolytic behaviour of pyrogallol various acoustic parameters were analyzed. Ultrasonic velocity, density and viscosity were determined and with the help of these three factors, isentropic compressibility ()s), shear relaxation time (,s), intermolecular free length (Lf), apparent molar compressibility (k), solvation number (Sn), acoustic impedance (Z), molar sound velocity (R), relative association (RA), etc. were calculated. The results indicated linear decrease and linear increase in above acoustic parameters except shear relaxation time and reduced viscosity, which do not show a regular trend. These results satisfy Bachem’s equation. Thus, pyrogallol behaves like a weak electrolyte in solvents like methanol, ethanol and n-prapanol and shows electrolytic behaviour in the order methanol > ethanol > n-propanol.
3. Ultrasound Velocity, Density and Viscosity and other Acoustic Parameters of p-benzoquinone with T.H.F. At Different Temperature
Author : Santosh Kumar, Avanesh Kumar, Vipin Kumar
Keyword : pyrogallol, Ultrasonic velocity, density and viscosity

Volume: 7,Issue:1,PP: 13-16,Year:(2015)
Ultrasound velocity, density and viscosity measurements have been made for p-benzoquinone with T.H.F. at the temperature 303.15K and 308K having the concentration of p-benzoquinone in the range of 0.01 to 0.10 mole/litre. These measurements have been used to evaluate some important parameters such as isentropic compressibility, lowering compressibility, specific viscosity and reduced viscosity for the same concentration and temperature range, these parameters have been discussed in the terms of solute-solvent interactions. The ultrasound velocity increased with increasing concentration of electrolyte.
4. Unsteady MHD Free Convective Flow through Porous Medium with Hall Current and Chemical Reaction
Author : Diwari Lal
Keyword : MHD, porous medium, hall current, chemical reaction, finite difference method

Volume:7,Issue:1,PP: 17-32,Year:(2015)
In this paper we investigate the effects of Chemical Reaction, Hall currents, Soret and Dufour on unsteady MHD free convective flow through porous medium in the presence of a magnetic field and first order chemical reaction. The similarity solutions were obtained using suitable transformations and the resulting similarity ordinary differential equations were solved by finite difference method. A parametric study illustrating the influence of different flow parameters on velocity, temperature and concentration fields are investigated. The effects of the various physical parameters on these fields are discussed with help of tables and graphs.
