The Effect of Renal Sympathetic Denervation (RSD) in Atrial Fibrillation (AF) Inducibility  [PDF]
Indra Prasad Upadhyay, Jialu Hu, Wugeti Naji Na, Wang Kun, Taji Di Linuer, Zhao Li, Alia  , Yuemei Hou
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.44020
Abstract: Objective: The purpose of this study is to investigate the effects of renal sympathetic nerve stimulation (RSN-S) and ablation (RSN-A) on atrial effective refractory period (ERP) and AF in normal canine heart. Atrial Fibrillation (AF) is a complex disease and one of the most frequent arrhythmias, especially in elderly patients. Multiple mechanisms are involved including interaction between the autonomic nervous system (ANS), electrophysiological properties of the atria, and vulnerability for AF. Cardiac overload increases the incidence of AF. In lone AF the triggers are in the pulmonary veins. AF caused by underlying disease has different mechanism. Atrial fibrillation (AF) is associated with activity of renin-angiotensin-aldosterone system (RAAS). Reduction in renal nor-adrenaline spillover could be achieved after renal sympathetic denervation (RSD). Methods: 1) Establish of atrial fibrillation model; 2) Ventricular rate analysis of AF; 3) Statistical analysis. Results: 1) The establishment of atrial fibrillation model; 2) Inducibility and duration of AF; 3) The changes of AERP dispersion. Conclusion: Left RSN-S shortened left atrial ERP, increased ERP dispersion, but did not change right atrial ERP. Bilateral RSN-A produced significant prolongation in both atrial ERP, but did not affect ERP dispersion. The on time of RD effect is at 4 hrs after RD procedure and the RD effect on AF will last for 20 hrs after RD procedure.
Social and Environmental Impacts of REDD+ Strategy: An Exploratory Analysis of Nepalese Case  [PDF]
Thakur Prasad Upadhyay, Khem Raj Bhattarai
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.210009
Abstract: This study explores the issues related to social and environmental impacts that would be generated from REDD+ (Reducing Emissions from Deforestation and Forest Degradation, and enhancing carbon storage in the forest ecosystem) intervention in Nepal. Data and other relevant information for the study have been gathered from relevant literature, stakeholder meetings, expert consultation and various websites. A SWOT (Strength, Weakness, Opportunity and Threat) analysis of REDD+ mechanism was carried out to evaluate its features. First, we reviewed and synthesized the relevant policies, plans, laws, acts, rules and regulations along with the World Bank’s Safeguard Policies relevant to REDD+. The details of Strategic Environmental and Social Assessment (SESA) have been described. We present a first stage exploratory SESA framework by considering different sectors, components and institutions related to REDD+ in a holistic way. This will, in turn, form a sound basis for the detailed SESA studies in the final phase of REDD+ implementation, which later develops a comprehensive Environmental and Social Management Framework. Our analysis shows that some of the potential social and environmental impacts are overlapping, and there are gaps in terms of existing policies and institutions in order to effectively implement the REDD+ strategy in Nepal.

Attitudinal Difference Among Women Of Different Educational Status Towards Infant And Mother Care
Papiya Upadhyay and Deb Prasad Sikdar
Al Ameen Journal of Medical Sciences , 2009,
Abstract: Children are the gem of the future. They contribute utmost to the national development of a country. If a country has healthy population, it can fight against all odds. In order to achieve this women come into the forefront. Women in their development process become mothers. A healthy mother can only give rise to healthy babies. The concern for the health of women is very significant and thus cannot be neglected. Against this back drop our present study aims to find out the relationship between women’s educational level and their attitudinal difference towards infant and personal care. The effect of marital status and location variations- rural and urban areas of Nadia district are also taken into consideration. The statistical analyses reflect mothers with higher educational status have positive attitude towards mother (personal) and infant care. The rural women lag far behind their urban counterparts in this respect. There is no significant difference between married and unmarried women in attitude towards infant and mother care.
The model for self-dual chiral bosons as a Hodge theory
Sudhaker Upadhyay,Bhabani Prasad Mandal
Physics , 2011, DOI: 10.1140/epjc/s10052-011-1759-2
Abstract: We consider (1+1) dimensional theory for a single self-dual chiral boson as classical model for gauge theory. Using Batalin-Fradkin-Vilkovisky (BFV) technique the nilpotent BRST and anti BRST symmetry transformations for this theory have been studied. In this model other forms of nilpotent symmetry transformations like co-BRST and anti co-BRST which leave the gauge-fixing part of the action invariant, are also explored. We show that the nilpotent charges for these symmetry transformations satisfy the algebra of de Rham cohomological operators in differential geometry. The Hodge decomposition theorem on compact manifold is also studied in the context of conserved charges.
Gaugeon formalism in the framework of generalized BRST symmetry
Sudhaker Upadhyay,Bhabani Prasad Mandal
Physics , 2014, DOI: 10.1093/ptep/ptu050
Abstract: We consider gaugeon formulations which discuss the quantum gauge freedom covariantly in the framework of generalized BRST transformation for the Yang-Mills theory as well as the BRST invariant Higgs model. We generalize the BRST symmetries of both the Yang-Mills theory and the Higgs model by making the transformation parameter finite and field-dependent. Remarkably, we observe that the gaugeon Lagrangian which describe the quantum gauge freedom appear automatically in the effective theories along with the natural shift in gauge parameters under specific finite field-dependent parameters.
Generalized BRST symmetry for arbitrary spin conformal field theory
Sudhaker Upadhyay,Bhabani Prasad Mandal
Physics , 2014, DOI: 10.1016/j.physletb.2015.03.066
Abstract: We develop the finite field-dependent BRST (FFBRST) transformation for arbitrary spin-s conformal field theories. We discuss the novel features of the FFBRST transformation in these systems. To illustrate the results we consider the spin-1 and spin-2 conformal field theories in two examples. Within the formalism we found that FFBRST transformation connects the generating functionals of spin-1 and spin-2 conformal field theories in linear and non-linear gauges. Further, the conformal field theories in the framework of FFBRST transformation are also analysed in Batalin-Vilkovisky (BV) formulation to establish the results.

International Journal of Geosciences (IJG) , 2014, DOI: 10.4236/ijg.2014.56057
Abstract:

The Par-Tapi-Narmada river link envisages transfer of surplus water from west flowing rivers between Par and Tapi in Gujarat State, India to water deficit areas in North Gujarat. The scheme is located mainly in southern Gujarat but it also covers part of the areas of Maharashtra, North of Mumbai on the Western Ghats of India. The main aim of Par-Tapi-Narmada link is to transfer the surplus waters of Par, Auranga, Ambica and Purna River basins to take over part of Narmada Canal command (Miyagam branch) after providing enroute irrigation. It is proposed that water saved in Sardar Sarovar Project, as a result of this transfer, would be taken further northwards to benefit water scarce areas of north Gujarat and also westwards in Saurashtra and Kutch regions. The construction of seven reservoirs on Par-Tapi-Narmada River Link Project would affect land use/land cover, settlements and infrastructure facilities within and around reservoir area. Thus, the submergence impact analysis of all the seven reservoirs of this project have been carried out by using remote sensing and GIS techniques for planning and designing of the structures. Out of the seven reservoirs, the paper discusses submergence analysis of Kelwan Dam reservoir which is located in geologically complex region of the Dangs district. The study attempts to assess the present problems of submergence of land, forest, agriculture, settlements and infrastructure facilities by using GIS techniques for taking alternative remedial measures prior and during construction of the dams.

Abstract: Supply chain optimization for biomass-based power plants is an important research area due to greater emphasis on green energy sources. This paper develops and applies two optimization models to analyze the impacts of biomass competition on cost structures and gross margins for four competing biomass-based power plants in northwestern Ontario. Model scenarios are run to study the impacts of changes in parameters relevant to biomass type and processing technology, and prices of inputs and outputs on procurement costs. Cost minimization model shows that per unit procurement costs are directly proportional to the size of the power plants in all scenarios. Profit maximization model, on the other hand, shows that FMUs that are closer to the power plants make higher gross margins. However, the margins significantly increase for FMUs that are close to the power plants potentially offering higher prices. The variations in costs and gross margin structures under various model scenarios are explained by location of depletion cells relative to power plants, availability of each type of biomass in depletion cells, biomass demands, and differential processing costs for two types of biomass. These results can aid decision makers to make improved decisions related to biomass supply chains for bioenergy production. 1. Introduction Forest biomass has been recognized as an alternative energy source since it is renewable and CO2 neutral [1]. However, renewable energy production from forest biomass faces many challenges due to uncertainty of its continuous supply [2–4]. The ever increasing demand of biomass for bioenergy production has enormously increased the transportation distances and costs for forest biomass procurement, which is spread over large geographical locations at varying distances from the power plant [1, 5]. Further, the optimal harvest schedules become complicated if more power plants compete for available biomass feedstock over given space and time. This suggests a need for developing and using optimization models to analyze such problems for improved decision making in bioenergy production. Canada’s dependence on fossil fuel has changed in recent times, and forest biomass has become an important part of its energy picture, supplying about 4.7% of our primary energy demand, the second largest source of renewable energy after hydroelectricity [6]. A major application of bioenergy is found in the forest products industry of Canada. Beyond the forest industry, several independent power plants generate electricity from forest biomass in Canada.
