Realization of Potassium Chloride Sensor Using Photonic Crystal Fiber  [PDF]
Gopinath Palai, Nilambar Mudului, Santosh K. Sahoo, Sukanta K. Tripathy
Soft Nanoscience Letters (SNL) , 2013, DOI: 10.4236/snl.2013.34A005
Abstract: We propose to measure the concentration of potassium chloride using photonic crystal fiber having circular air holes of diameter 400 nm. The principle of measurement is based on the linear variation of the transmitted field emerging from the PCF with respect to concentration of potassium chloride. Field distribution in photonic crystal structure is simulated using plane wave expansion (PWE) method. Simulation result reveals that the intensity of transmitted light varies linearly with respect to concentration of potassium chloride filled in the air holes.
Characterization of new variety of Chrysanthemum by using ISSR markers
Palai, SK;Rout, Gyana Ranjan;
Horticultura Brasileira , 2011, DOI: 10.1590/S0102-05362011000400029
Abstract: chrysanthemum is the important cut flower after rose among the ornamental plants traded in the global flower market. it is propagated vegetatively and also has a strong sporophytic self-incompatibility system as shown by all members of asteraceae family. morphologically, the petal numbers and flower colours present maximum variation when compared to existing varieties. twenty inter simple sequence repeat primers were used to detect the new variety of chrysanthemum developed through spontaneous sporting. the results indicate that the rate of polymorphism showed significant differences as compared to other existing varieties. the average number of amplification products per primer was eight. the size of issr amplified fragments varied from 0.25 - 2.4 kbp. therefore, issr marker is a useful technique for the rapid and easy assessment of genetic variation among the variants. morphological traits of new variants showed variation as compared to other parents. the 1st flower bud appearance and the height of 1st bud of the variant were less as compared to original mother variety. the new variants can be propagated in large scale commercially through in vitro technique.

Oral hygiene practices and habits among dental professionals in Chennai
Gopinath V
Indian Journal of Dental Research , 2010,
Abstract: Aims and objectives : The present study was carried out to assess the oral hygiene practices and habits among practicing general dentists. Materials and Methods : The study was carried out in four dental schools with the help of a self administered questionnaire. The questionnaire covered dentists′ oral self care, smoking habits, professional reading and oral health concepts. A total of 700 dentists responded, of which 457 were males. Recommended oral self care (ROSC) included tooth brushing one per day, eating sugary snacks daily or rarely and regularly using fluoride tooth paste. Results : The data obtained was then subjected to statistical analyses and evaluated using chi-square tests and logistic regressions.It was found that 55.9% of all respondents brushed twice a day, 59.4% consumed sugar containing snacks less than once daily and 55.1% of them used fluoride containing paste regularly while brushing. 81.1% of the 700 dentists never used tobacco products. In all, 19.6% 0f the practicing general dentists followed recommended oral self care. Conclusion : From the present study, it can be concluded that only 19.6% of south Indian dentists follow recommended oral self care and hence awareness programs and continuous dental education programs among dentists is essential to improve the present scenario and to increase the number of dental professionals following ROSC.

Law demands "Care" - not "Cure"
Shenoy Gopinath
Journal of Gynecological Endoscopy and Surgery , 2009,
Abstract: In today′s medicolegal scenario specially related to endoscopic surgery, patient expects a miraculous result or a definite cure.However the author who has experience of both the fields i.e. gynecological endoscopy and medicolegal aspects, clears that the law doesn′t expect a 100% cure but expects proper medical care by the concerned gynecologist, gynecological endoscopist. Patient also has to be informed about this important fact.

Droplet rebound from rigid or strongly hydrophobic surfaces
A. Gopinath
Physics , 2005,
Abstract: A weakly deformable droplet impinging on a rigid surface rebounds if the surface is intrinsically hydrophobic or if the gas film trapped underneath the droplet is able to keep the interfaces from touching. A simple, physically motivated model inspired by analysis of droplets colliding with deformable interfaces is proposed in order to investigate the dynamics of the rebound process and the effects of gravity. The analysis yields estimates of the bounce time that are in very good quantitative agreement with recent experimental data (Okumura et. al., (2003)) and provides significant improvement over simple scaling results.
eAnt-Miner : An Ensemble Ant-Miner to Improve the ACO Classification
Gopinath Chennupati
Computer Science , 2014,
Abstract: Ant Colony Optimization (ACO) has been applied in supervised learning in order to induce classification rules as well as decision trees, named Ant-Miners. Although these are competitive classifiers, the stability of these classifiers is an important concern that owes to their stochastic nature. In this paper, to address this issue, an acclaimed machine learning technique named, ensemble of classifiers is applied, where an ACO classifier is used as a base classifier to prepare the ensemble. The main trade-off is, the predictions in the new approach are determined by discovering a group of models as opposed to the single model classification. In essence, we prepare multiple models from the randomly replaced samples of training data from which, a unique model is prepared by aggregating the models to test the unseen data points. The main objective of this new approach is to increase the stability of the Ant-Miner results there by improving the performance of ACO classification. We found that the ensemble Ant-Miners significantly improved the stability by reducing the classification error on unseen data.
Construction of Environmental Knowledge: Experiences from India
Deepak Gopinath,Manik D Gopinath
Journal of Sustainable Development , 2009, DOI: 10.5539/jsd.v1n1p2
Abstract: This paper explored key issues in how knowledge of the environment is constructed in the Third World. Drawing on which, it showed that there are both explicit and implicit ways in which this knowledge is contested. Particularly, it discussed how implicit forms of contestation are problematic in Third World economies because they are exclusionary and also where such issues become ‘headlines’ only after environmental damage and accompanying social injustices have resulted. It concludes by raising crucial questions for environmental research in the Third World where there is limited role of governments and communities in protecting their environment.
