HOW DO WE LEARN ANOTHER LANGUAGE?
Arun Behera
The Dawn Journal , 2012,
Abstract: Language is a system of arbitrary vocal symbols used by a social group. It may be either spoken or written. Every human being uses a language to communicate to other members of the society (s)he is a part of. While we acquire our mother tongues (L1), we learn the other language(s). Linguists talk of several approaches to language learning process, more prominent approaches being grammar-translation, direct, audio-lingual and contrastive analysis. Similarly, four of the major skills such as listening, speaking, reading and writing (LSRW) are also involved in language learning process. Our learning an additional language enriches and helps us build a communication rapport with a larger society or social group.
MOTHER TONGUE (L1) Vis-A-Vis OTHER TONGUE (L2)?
Arun Behera
The Dawn Journal , 2012,
Abstract: Learning a language is always a difficult thing and more so when it comes to learning a second language (L2) for it reflects the complexity of learning a language which is the other tongue rather than the mother tongue of a person. The present paper proposes to focus on the prospects and benefits of the skill-based learning of the L2. All learners, as such pick up a language by two means: a) acquisition of one's own language/mother tongue, and b) learning another language. Acquisition is a subconscious and intuitive process, similar to that used by a child to pick up the first language (L1); and the second is conscious learning, in which a learner is aware of his/her own learning process.
PHONETICS IN LANGUAGE LEARNING?
Arun Behera & Tripathy
The Dawn Journal , 2012,
Abstract: The present paper aims at finding out if Phonetics as a branch of study has got something to do with the manner we learn a language, English in this case. Attempts will be made to find out how various aspects of phonetics such as word stress, accent and rhythm, intonation etc. help one in learning English. It need not be stressed here that most of these aspects play a crucial role in how we pick up a language, especially the spoken part, for we need to be aware of how each syllable or a word or a group of words is pronounced. In order to learn English well, it is necessary that the learner understands the phonetic nuances of the target language because her or his mother tongue do not use the same stress pattern or the tones. It is therefore challenging to master all the stress patterns and tones of English. It is significant to note here that the manner in which a learner pronounces a word/phrase; or puts the stress/tone; or combines/substitutes one set of words/sounds tells us about the learner's social/geographical/literacy/economic/emotional status. We have tried to present only a cursory outline of the steps that may be taken to learn the sounds of the target language. We have not dealt with many other essential technical information on sounds, their combinations, the contexts in which 'similar' sounds could be grouped together and used as if the group is a single sound unit, etc.
Stratigraphic Control of Petrography and Chemical Composition of the Lower Gondwana Coals, Ib-Valley Coalfield, Odisha, India  [PDF]
Alokranjan Senapaty, P. Behera
Journal of Geoscience and Environment Protection (GEP) , 2015, DOI: 10.4236/gep.2015.34007
Abstract: The Ib-valley coalfield of Odisha, India contains five coal seams viz. Ib-seam at the bottom overlain successively by Rampur seam, Lajkura seam, Parkhani seam and Belpahar seam. Twenty one representative samples were collected from three major seams (Ib, Rampur and Lajkura) and their petrography and chemical studies were carried out. Samples were not collected from the Parkhani and Belpahar seams as these are very small seams exposed locally having no regional correlation. The macroscopic study shows the dominance of durain which imparts a dull appearance to these coals. The maceral analysis reveals that vitrinite percentage varies from 4.5% to 80.2%, the exinite from 3.30% to 22.2% and the inertinite from 12.5% to 92.2% in different samples of the Ib valley coalfield. The very high proportion of inertinite suggests a shallower water deposition of plant materials followed by prolonged period of exposure and repeated cycle of weathering. The proximate analysis results show that the top Lajkura seam is comparatively lower in rank than the underlying Ib and the Rampur seam. The ultimate analysis exhibites that the percentage of variation in C is found from 77.88 to 85.79, H from 4, 4 to 5.91 and O from 7.26 to 15.3. H/C and O/C ratio including C.V. in this coalfield showing distinct variations from the bottom to top seam. The analyses results indicate that the petrographic and chemical characters of the ib valley coals are stratigraphically controlled.
Prediction and Analysis of Deposition Efficiency of Plasma Spray Coating Using Artificial Intelligence Method  [PDF]
Ajit Behera, S. C. Mishra
Open Journal of Composite Materials (OJCM) , 2012, DOI: 10.4236/ojcm.2012.22008
Abstract: Modern industrial technologies call for the development of novel materials with improved surface properties, lower costs and environmentally suitable processes. Plasma spray coating process has become a subject of intense research which attempts to create functional layers on the surface is obviously the most economical way to provide high per- formance to machinery and industrial equipments. The present work aims at developing and studying the industrial wastes (Flay-ash, Quartz and illmenite composite mixture) as the coating material, which is to be deposited on Mild Steel and Copper substrates. To study and evaluate Coating deposition efficiency, artificial neural network analysis (ANN) technique is used. By this quality control technique, it is sufficient to describe approximation complex of in- ter-relationships of operating parameters in atmospheric plasma spray process. ANN technique helps in saving time and resources for experimental trials. The aim of this work is to outline a procedure for selecting an appropriate input vec- tors in ANN coating efficiency models, based on statistical pre-processing of the experimental data set. This methodology can provide deep understanding of various co-relationships across multiple scales of length and time, which could be essential for improvement of product and process performance. The deposition efficiency of coatings has a strong dependence on input power level, particle size of the feed material, powder feed rate and torch to substrate distance. ANN experimental results indicate that the projection network has good generalization capability to optimize the deposition efficiency, when an appropriate size of training set and network is utilized.
A comment on the Invariance of the Speed of Light
Harihar Behera
Physics , 2003,
Abstract: The invariance of the speed of light in all inertial frames is shown to be an inevitable consequence of the relativity principle of special relativity contrary to the view held by Hsu and Hsu in taiji relativity where the speed of light is no longer a universal constant. The present approach is not only new but also much simpler than the existing approaches.

Abstract: The possibility of a Newtonian gravitomagnetic field is considered here with its immediate and far-reaching implications for the interpretation of 2004 LAGEOS experimental results confirming the general relativistic prediction of Lense-Thirring effect.
Effect of a relativistic correction to the Coulomb potential on the energy levels of hydrogen atom
Harihar Behera
Physics , 2012,
Abstract: Based on classical electrodynamics, it is argued that the Coulomb potential (which is strictly valid for two point charges at rest), commonly used in the study of energy levels of hydrogen atom is not the correct one, because the electron in the hydrogen atom moves with relativistic speeds with respect to the nucleus. Retardation effect has to be considered in accordance with Li\'{e}nard-Wiechert (or retarded) potential of a moving charge or the relativistic electrodynamics. However, such a consideration introduces a correction to the Coulomb potential, whose quantum mechanical expectation value is estimated at $E_{ret} = - \frac{mc^2\alpha ^4}{2n^3(l+1/2)}$, which is of the same order as the fine structure of hydrogen atom and hence added to the standard energy eigenvalue values of H-atom. This correction lifts the $l$-degeneracy in the spectra of H-atom and hence modifies the standard result. The result disturbs the existing agreement between the theory and experiments on H-atom and hence requires further theoretical and experimental re-examination. The implications of this result for the Kepler-problem in general is also discussed in the context of Heaviside's gravity, which seems to offer an alternative explanation for the non-Newtonian perihelion advance of Mercury without invoking the space-time curvature formalism of Einstein's general theory of relativity.
Gravitational Thomas Precession and the Perihelion Advance of Mercury
Harihar Behera
Physics , 2003,
Abstract: Gravitational Thomas Precession (GTP) is the name given to Thomas Precession when the acceleration is caused by a gravitational force field. The GTP gives a negative contribution of 7.163 arcsec/century for the anomalous perihelion advance of Mercury's orbit. This effect seems to be of some concern for the General Relativity.
Is there a Gravitational Thomas Precession ?
Harihar Behera
Physics , 2003,
Abstract: Gravitational Thomas Precession (GTP) is the name given to Thomas Precession when the acceleration is caused by a gravitational force field. The contributio n of the GTP to the the anomalous perihelion advance of the orbit of Mercury is here estimated at $\dot{\tilde{\bf\omega}}_{GTP} = 21\cdot49 [ 1 + \frac{(\vec L \cdot \vec S)}{L^{2}} ] {arcsec/century} $,where $ \vec L $ and $ \vec S $ respectively represents the orbital angular momentum and the spin angular momentum of Mercury .This effect seems to be of some serious concern for the General Relativity.
