Pharmacognostic and antihyperglycemic study of Coccinia indica
Manish Gunjan,Goutam K. Jana,A. K Jha,Umashanker Mishra
International Journal of Phytomedicine , 2011,
Abstract: A comprehensive herbal drug therapeutic regimen offers time tested safe and effective support to conventional therapy in the management of diabetes. This is combination with adequate dietary management and physical activity would provide an integrated approach to the management of this deadly disease, particularly Type 2 diabetes. Additionally, due to unlimited potential of herbal drugs for innovative bioactive molecules, all efforts should be made to adopt a package of best practices encompassing conservation, cultivation, quality control, standardization and research and development for medicinal plants and herbals. Chronic administration of kundru fruit extracts (200mg/kg)for 14 days reduces the blood glucose level of the diabetes induced animals as compared to diabetic control group. There was significant decrease in the blood glucose level in the 7th[p<0.01] and 14th [p<0.001] days of the diabetes induction, showing antidiabetic effect of the concern fruit. The effect was comparable to that of standard antidiabetic drug Glibenclamide. The hypoglycemic effect of orally administered extracts of leaves and roots of Coccinia indica has been reported earlier but none of the literatures or paper shows the antidiabetic activity of fruit of the above plant as in crude extract while the whole fruit extract shows significant anti diabetic activity.

Consumption Value of Digital Devices: An Investigation through Facebook Advertisement  [PDF]
Abhishek Mishra
Social Networking (SN) , 2015, DOI: 10.4236/sn.2015.43007
Abstract: Data collection represents the most effort-intensive stage of any marketing research exercise, especially in cases sampling frame is unavailable. Sub-optimal bypasses in form of student surveys or surveys employing convenience sampling have become common. In modern era, where laptops and smartphones enable easy accessibility of respondents online, this study utilizes Facebook advertisement as a source of data collection to measure the construct of user experience for interactive products. Modern digital devices, like smartphones, are a source of a variety of experiences for the user. Design teams at various smartphone manufacturers are struggling every day to create products which provide complete consumer experiences. This work not only proposes a framework for describing the same with usability, social value and pleasure in use, but also tests the scales for each by empirical validation. Data collection process through Facebook, as a sample frame, is something yet to be seen in marketing literature. This work goes the distance in not only demonstrating the efficacy of using Facebook advertisement as a viable data collection tool but also developing a framework to measure consumption value. Outcomes of the study, should promote further research using this sampling frame for future research, especially in the area of marketing.
Effect of Deformation of Red Cell on Nutritional Transport in Capillary-Tissue Exchange System  [PDF]
Rekha Bali, Swati Mishra, Mamta Mishra
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.211200
Abstract: A mathematical analysis of a model for nutritional exchange in a capillary-tissue exchange system is presented in this paper. This model consist of a single file flow of red blood cell in capillary when diameter of red blood cell is greater than tube diameter, In this case, the cell must be deformed. Due to concentration gradients, the dissolved nutrient in substrate diffuses into surrounding tissue. Introducing approximations of the lubrication theory, squeezing flow of plasma in between the gap between cell and capillary wall have been solved with the help of approximate mathematical techniques. The computational results for concentration of dissolved nutrients, diffusive flux and normal component of velocity have been presented and discussed through graphs. We have also shown the effect of deformation parameter and permeability on these results.
Phase Wise Supply Chain Model of EOQ with Normal Life Time for Queued Customers: A Computational Approach  [PDF]
Sant Sharan Mishra, Prem Prakash Mishra
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.23036
Abstract: In this paper, we mainly aim to compute the optimal inventory in the phase wise supply chain for queued customers in the interval of lower and upper bounds with particular life of the items. Important performance measures such as total optimal cost of the system and total expected delivery have also been computed by applying the dynamic programming and Drichlet theorem. Finally, numerical demonstration and sensitivity analysis have also been presented to gain the better perspective of the model.
Monte Carlo Integration Technique for Method of Moments Solution of EFIE in Scattering Problems  [PDF]
Mrinal MISHRA, Nisha GUPTA
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2009, DOI: 10.4236/jemaa.2009.14039
Abstract: An integration technique based on use of Monte Carlo Integration is proposed for Method of Moments solution of Electric Field Integral Equation. As an example numerical analysis is carried out for the solution of the integral equation for unknown current distribution on metallic plate structures. The entire domain polynomial basis functions are employed in the MOM formulation which leads to only small number of matrix elements thus saving significant computer time and storage. It is observed that the proposed method not only provides solution of the unknown current distribution on the surface of the metallic plates but is also capable of dealing with the problem of singularity efficiently.
Design of Hybrid Fuzzy Neural Network for Function Approximation  [PDF]
Amit Mishra, Zaheeruddin Zaheeruddin
Journal of Intelligent Learning Systems and Applications (JILSA) , 2010, DOI: 10.4236/jilsa.2010.22013
Abstract: In this paper, a hybrid Fuzzy Neural Network (FNN) system for function approximation is presented. The proposed FNN can handle numeric and fuzzy inputs simultaneously. The numeric inputs are fuzzified by input nodes upon presentation to the network while the Fuzzy rule based knowledge is translated directly into network architecture. The connections between input to hidden nodes represent rule antecedents and hidden to output nodes represent rule consequents. All the connections are represented by Gaussian fuzzy sets. The method of activation spread in the network is based on a fuzzy mutual subsethood measure. Rule (hidden) node activations are computed as a fuzzy inner product. For a given numeric o fuzzy input, numeric outputs are computed using volume based defuzzification. A supervised learning procedure based on gradient descent is employed to train the network. The model has been tested on two different approximation problems: sine-cosine function approximation and Narazaki-Ralescu function and shows its natural capability of inference, function approximation, and classification.
Menopausal transition and postmenopausal health problems: a review on its bio-cultural perspectives  [PDF]
Shailendra Kumar Mishra
Health (Health) , 2011, DOI: 10.4236/health.2011.34041
Abstract: This paper documents health problems faced by menopausal and postmenopausal women. These women constitute a sizable proportion of India's population though there exist no health care programmes to cater their specific health needs and health vulnerabilities arose due to menopausal transition. Researchers have generally tried to determine age at menopause and a few have explored psychosomatic problems experienced by them. Abrupt changes in hormone levels among women generally bring out several physical infirmities which have hardly been the interest of research. Studies on menopausal and postmenopausal health problems and their bio-cultural correlates are warranted. Efforts should be made to understand the process of aging among women in relation to menopausal transition. Cross-cultural differences in coping mechanisms to minimise the health problems arose due to menopausal transition are important to study. This review argues provision of culturally appropriate health care programs to facilitate easier menopausal transition and to ensure healthy postmenopausal life for women.

Anoop Kumar Mishra
Atmospheric and Climate Sciences (ACS) , 2012, DOI: 10.4236/acs.2012.22023
Abstract: In this paper, an effort has been made to study heavy rainfall events during cyclonic storms and active monsoon cycle over Indian land and associated oceanic regions from recently developed merged rainfall technique using rain gauge and multi-satellite observations from Precipitation Radar (PR) onboard Tropical Rainfall Measuring Mission (TRMM), Special Sensor Microwave Imager (SSMI) onboard Defense Meteorological Satellite Program (DMSP) and Meteosat of Eumetsat. Four recent cyclonic events namely Gonu, Bijli, Aila and Laila were qualitatively analyzed using rainfall from this technique. This technique is validated against another merged rainfall product TRMM-3B42V6 and rain gauge observations during heavy rainfall events of the years 2007, 2008, 2009, 2010. Results presented in this study show that the heavy rainfall events are efficiently monitored by this technique.

Hradyesh Kumar Mishra
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.310174
Abstract: In this paper, variational iteration method and He-Laplace method are used to solve the nonlinear ordinary and partial differential equations. Laplace transformation with the homotopy perturbation method is called He-Laplace method. A comparison is made among variational iteration method and He-Laplace. It is shown that, in He-Laplace method, the nonlinear terms of differential equation can be easily handled by the use of He’s polynomials and provides better results.
