 Abstract

Chakrata, Jaunsar-Bawar region is conferred by diverse wealth in terms of flora. The flora is so wealthy just because of the microorganism which inhabits the soil. Pseudomonas fluorescens belongs to the PGPR (plant-growth promoting rhizobacteria), which plays a major role in plant growth promotion and reduce severity of various diseases, bio-control agent as well as antagonist, and a potential biosurfactant producer. A total of six soil samples were collected from different villages of chakrata. Dilutions of soil sample were made and isolated on the nutrient agar medium followed by identification through Gram�s staining and different biochemical analysis. Different tests were performed for each isolated bacterias from different soil samples. Out of which four samples showed the presence of Pseudomonas fluorescens strains according to the Bergey�s manual of determinative bacteriology. Seeds of black-eyed peas(lobia) and okra(bhindi) were treated with isolated strains of P.fluorescens . After treating them, seeds were sown in the pots. A pot as a control is taken for the comparison of growth between inoculated and uninoculated seeds. The inoculated seeds showed positive growth than control. The present study indicates that the presence of Pseudomonas species in soils of chakrata is selective in nature and supports the well growth of selected plants and this is one of the main reasons for the well productivity of different varieties of crops and medicinal plants in chakrata, jaunsar-bawar areas.

 Abstract

Factor, the ratio between the real or average power and the apparent power forms a very essential parameter in power system. It is indicative of how effectively the real power of the system has been utilized. Hence, there is a continuous need for power factor improvement and reduction of line current harmonics. Development of new circuit topologies and control strategies for Power Factor Correction (PFC) and harmonic reduction has become still more essential with the introduction of strong technical IEC standards. This project aims to develop a circuit for PFC using active filtering approach by implementing two boost converters arranged in parallel. It shall be based on an optimised power sharing strategy to improve the current quality and at the same time reduce the switching losses. The work initially involves simulation of basic power electronic circuits and the analysis of the current and voltage waveforms. It starts with simple circuits with a gradual increase in complexity by inclusion of new components and their subsequent effect on the current and voltage waveforms. We focus on the objective of improving the input current waveform i.e. making it sinusoidal by tuning the circuits. All the simulation work is done in MATLAB Simulink environment and the Power results are attached herewith.

 Abstract

The Indo-Islamic-Persian style was the distinguished and chief characteristic feature of the Mughal architecture which was flourished on the Indian subcontinent during the reign of Mughal Empire (1526�1857). This new style was a result of combination of elements of Islamic art and architecture, which were introduced to India by the Delhi Sultanate (1192�1398) and had produced great monuments such as the Qutub Minar which consist the features of Persian art and architecture. Mughal monuments are found chiefly in north India and many remains can be found in Pakistan too. Rolling vines and flowers, jewels, and crowns in greens, blues, and gold embellish Mughal buildings. The main aim of this paper is to describe the beauty of the Mughal Architecture which enriched the field of architecture in India.

 Abstract

In the ever changing economic scenario globalization, liberalization and privatization policies of the Government, in recent years, have made an ineffaceable impact by bringing into force new economic system in India. Over the centuries system of taxation has been shaped and reshaped to make it acceptable, effective and efficient. The journey of restructuring the tax system has been going on to make it more and more meaningful. Goods and Services Tax (GST) is considered to be a best solution for all these issues and which is expected to bring in tax efficiency, simplicity, transparency and degree of harmonization to the tax base, tax rates as well as tax infrastructure. More than 160 countries around the world have already implemented GST and implementation of GST in India would bring in similarity. Now, implementation of GST has become certain in India and it is a right time to understand it. So this paper tries to throw a light on various aspects of GST and to know its probable impact on Indian economy, India sales tax rate-GST, GDP growth. The data are collected through various Primary and secondary sources like reports of Government, professional bodies, working committees and also from research papers, articles, news, budget sessions etc. As in other countries, the systemic reforms in the tax system in India in the 1990s were the product of crisis but the reforms were calibrated on the basis of comprehensive analysis. Tax reform since 1991 was initiated as a part of the structural reform process, following the economic crisis of 1991.
