A Study of Reduction of Vanadate
Vanadates are salts corresponding to oxidation state V of vanadium. The salts are pretty strong oxidizing agents having a standard potential comparable to that of nitric acid. Their structures and nature of species presents in solution have been extensively studied. The results show that in electronic configuration Vanadates show resemblance with phosphate to the extent that none of them is left with any unshared electron and both exist in modifications like Ortho, meta, pare etc. differing essentially in the water content of the acid and also in the extent of polymerization. However an important difference between the two is that whereas for phosphates the rate of interchange of different forms is quite slow, it is quite fast for Vanadates. Hence any form of vanadate when put into solution rapidly comes to an equilibrium common for all. This divergence in further manifested in their behavior towards acids. Increase of acidity in the case of phosphate lead to simpler molecules but for Vanadates as one passes from alkaline to acidic solutions the complexity of the vanadate ion raises leading ultimately to precipitation of (V 2 O 5) in about N/100 acid. On further increase in acidity the precipitate redissolves but now as a cation formulated variously as V. In this respect and in other chemical properties they are closer to chromates.

Review on EES Application in Power Engineering System
In view of the projected global energy demand and increasing levels of greenhouse gases and pollutants, there is a well-established need for new energy technologies which provide clean and environmentally friendly solutions to meet end user requirements. Present review work is an effort to study the electrical power generation because of the need to reduce greenhouse gas emissions and to introduce mixed energy sources. Review based on the present and future Electrical Energy Storage (EES) system which is recognized as underpinning technologies to have great potential in meeting these challenges, whereby energy is stored in a certain state, according to the technology used, and is converted to electrical energy when needed. Review work starts with an overview of the operation principles, technical and economic performance features and the current research and development of important EES technologies, categories based on the types of energy stored. Work intends to mitigate this problem by providing a comprehensive and clear picture of the state-of- the-art technologies available, and where they would be suited for integration into a power generation and distribution system. Moreover, comparison had been made between RES and EES system.

The Conflict Between Tradition And Modernity , R.K. Narayan’s – The Guide
R K Narayan was born in British ruled India in the erstwhile city of Madras later renamed Chennai in 1906 and most of his works related to the fictional south Indian town of Malgudi. Narayan who is often compared with William Faulkner, alike the latter dwells in the social contexts and the usual life of his characters with humor and compassion and the energy that propels common life as the appealing inspirations. In 1933, Narayan met and fell in love with a fifteen year old girl who lived in his neighborhood and going against all astrological advice disapproving proposed marriage went ahead to marry her and though the marriage not very long lived with his wife Rajam dying prematurely, her entry into his life started changing times for him in better ways. The first three books written by Narayan, deal with socially accepted evil practices.Overall different novels written by Narayan throws light which shows the conflict between Tradition and Modernity.

Structural Morphological and Electrical Study on PI/ ITO/ PVDF Ternary Composite Thin Films
Studies of polymeric ternary composite thin films incorporating inorganic materials are of immense importance for current technological applications. Polyimide (PI) composite thin films incorporating indium tin oxide (ITO) and poly (vinlylidene fluoride) (PVDF) at various weight ratios were processed using an in situ generation approach with the spin coating unit. The resultant product was imidized up to 350º C to test the ability of the material to endure high temperatures without affecting the host matrix. The structural and morphological behavior of the PVDF/ ITO/ PI composite films was investigated using Fourier Transform Infrared, Scanning Electron Microscopy and Atomic Force Microscopy characterization techniques. The degrees of crystallinity and PVDF/ ITO particle size within the PI matrix were studied using X-ray diffraction. The electrical properties were analyzed using Differential Scanning Calorimetry, UV-visible spectroscopy and the four-probe technique. An overall improvement in the properties of the composite films was observed in comparison to those of pure PI. The synergistic improvement in the composite films is associated with the interaction mechanism between ITO/ PVDF with PI, where ITO becomes dispersed and interacts within the PI and PVDF compound matrix. This leads to a decrease in available free-space volume and increases the surface enrichment providing reinforcement to the matrix.

Review on Religious Practice on Politics with Special Reference to Chhattisgarh State, India
The relation between religion and politics continues to be an important theme in political philosophy, in terms of political theorists and in practical political contexts. One reason for the importance of this topic is that religions often make strong claims on people’s allegiance in a particular community. In the new democracies the role of youth is of special importance. Young people always ready to face the challenge of fitting into an established political system or making changes. Hence these all issues related to religious politics motivated author to select this topic for review and hoping to explore the maximum of negative and positive aspect in the work. Moreover, study will focus how religious exercise in politics will influence effect the present youth with special reference to state Chhattisgarh, India.

Optimal Blending Of Fly Ash with Geospatial Characteristics of Soil
Soil is the basic foundation for any civil engineering structures. It is required to bear the loads without failure. In some places, soil may be weak which cannot resist the oncoming loads. In such cases, soil stabilization is necessary in this study, fly-ash is used as a stabilizing material to stabilize the expansive soil dealing with engineering characteristics as the parameter for it. Present paper describes a study carried out to check the improvement in the properties of expansive soil with fly-ash in varying percentages. Fly-ash is added in 10%, 20%, 30%, and 40% and the change in index properties and engineering characteristics is to be examined. In such cases, soil stabilization is necessary. Numerous methods are available in the literature for soil stabilization. But sometimes, some of the methods like chemical stabilization; lime stabilization etc. adversely affects the chemical composition of the soil. Hence, in this project we are going to have a check on variation in the properties of soils on addition of varying percentage of soil.
