Simulation Implementation of Different Types of Loads for High Gain Single Stage Boosting Inverter
This paper presents simulation implementation of different types of loads inr high-gain single-stage boosting inverter (SSBI) for photovoltaic applications. The two-stage micro inverter first performs dc to dc voltage step up and then converts dc to ac, whereas the single-stage topology has to perform the dc to dc voltage step up, and the dc to a c inversion functions all in one stage. The single stage boosting inverter system employs a Tapped Inductor to attain high-input voltage step up and, thus, allows operation from low dc input. The traditional two-stage approach is costly and has complex topology whereas the Single Stage Boosting Inverter has a simpler topology and a lower component count. The Single Stage Boosting Inverter can achieve high dc input voltage boosting, good dc–ac power decoupling, good quality of ac output waveform, and good conversion efficiency. The simulation results for linear R (Resistive) and RL (Inductive) loads as well as nonlinear RC and nonlinear resistor and saturable inductor loads are shown in this paper.

Corporate Social Responsibility in India: Issues and Challenges
The purpose of this article is to provide a broad summary of the value propositions evident in the research on the business case for Corporate Social Responsibility (CSR). Over a last 30 to 40 years, there has been a stable increase in information produced by small and large organizational set ups in relation to their social and environmental impacts. It is very well understood by organizations that govt. alone will not be able to succeed in its endeavor to uplift the downtrodden society for further compulsion of Corporate Social Responsibility (CSR) has filtered the myth that the ultimate goal is not profit making, rather trust building an assert able with societal relationship and only long term survival mantra for any organization. We would try to light on (CSR) of Indian organizations which would be helpful for both economic and social interest. This article is based on the secondary data and focuses on the findings & reviewing of the issues and challenges faced by Indian organizations with respect to Corporate Social Responsibility (CSR).Stockholders demand that corporate operations be managed efficiently and that improved market value reward their investments. Companies Act 2013, brought an end to the long run discussion on CSR practices by the corporates.The journey of CSR as a corporate responsibility has two broad perspectives, pre Companies Act 2013 and post Companies Act 2013. CSR policy is still in a nascent stage and faces number of challenges. The Union Budget 2015 clarified that any expenditure on the Swatch Bharat Abhiyan is to be claimed as deduction u/s 80 G and not under CSR. Thus, Indian law on CSR still awaits clarification on many areas wherein claiming deduction u/s 80, exemptions from tax and treating it as CSR all are in existence.

Comparative Study of Seismic Behaviour of Open Ground Storey Buildings, After Replacing Rectangular Columns with Circular Columns
The earthquake resistant design of structures requires that structures should sustain, safely, any ground motions of an intensity that might occur during their construction or in their normal use. However ground motions are unique in the effects they have on structural responses. The most accurate analysis procedure for structures subjected to strong ground motions is the Push over analysis. Pushover analysis is based on the assumption that structures oscillate predominantly in the first mode or in the lower modes of vibration during a seismic event. This leads to a reduction of the multi-degree-of-freedom, MDOF system, to an equivalent single-degree-of- freedom, ESDOF system, with properties predicted by a nonlinear static analysis of the MDOF system. The ESDOF system is then subsequently subjected to a nonlinear time history analysis or to a response spectrum analysis with constant-ductility spectra, or damped spectra. The seismic demands calculated for the ESDOF system are transformed through modal relationships to the seismic demands of the MDOF system. In this study the seismic behaviour of a frame building has been analysed by using push over analysis. The seismic performance evaluation of the building has been carried out by changing the sizes of the columns and also by replacing the rectangular columns with the circular columns. Static type of pushover analysis is to be used in this research work where the loads consist of permanent gravity loads and incremental horizontal forces at each storey level. Capacity curves (base shear versus story total drift) obtained from static pushover analysis using commercially available software called Etabs (Etabs 2015) are used for the calculation of some seismic demand parameters. The dimensions of the buildings have been kept constant and only the column sizes have been changed. Three different combinations of the rectangular column dimensions are taken and the non linear response of each is evaluated by using the pushover analysis. The rectangular columns are then replaced with the circular columns of suitable dimension. The buildings are designed for the gravity and seismic loadings as per IS 456: 2000 and IS 1893: 2002.

An Enlightment Of Diagnosis Of Pandu Vyadhi By Clinical Presentation And Its Management By Combination Of Aarogyavardhini Vati With Mandur Bhasm And Punarnavadi Mandur -A Single Case Study
There are many diseases which commonly occurs in all age groups, one of which is Pandu Vyadhi. In all Ayurveda samhita Pandu Vyadhi is described as a condition in which skin becomes pallor or yellowish white in colour. This disease comes under Raktdhatu Kshaya & Rasvaha Strotas dushti. It is correlated with anaemia, evaluation of its severity is done by haemoglobin percentage. Every disease can be diagnosed by two ways, one by clinical presentation & another way by pathological investigation. Pandu Vyadhi has Vishistha lakshanatmak presentation by this, primary diagnosis can be done & by haemoglobin percentage diagnosis can be confirmed on opd basis. Proper diagnosis helps in proper drug management. Aacharya Charak explained Mandur Bhasm &Punarnavadi Mandur as a drug management for Pandu Vyadhi. Aacharya Vagbhata suggests use of Aarogyavardhini vati. In this paper a single case study is presented. A male patient is diagnosed by clinical presentation &signs which further confirmed by Hb%evaluation which was 5.9gm%.Drug management is given in combination, after one month of follow up there is subjective improvement in patient & Hb%was 9.9 gm %is noticed. Which enlightens the importance of diagnosis & effect of drug management given.

Water Scarcity and Rain Harvesting Method- A Case Study of Diphu Town, Assam India
Water is the basic need for the all the living things in different ways including the ecosystem in which we are all part of. The importance of water is well known. Water is our most precious natural resources. Its uses are innumerable and its importance cannot be underestimated. Its role ranges from domestic uses, agricultural and industry to religious, recreation, landscape decoration and even therapy. Water is basic to life. Due to the growing population over the decades, millions of people worldwide suffer from the lack of water especially in the urban areas where population concentration is very high. Because of this the demand of water is very high with overuse of ground water resulted in a drop in water table levels and have made the cost of water is high. It is found that rain harvesting, the collection of rain water from surfaces upon which it falls, is a long standing practice of many countries still use as a means for dealing with water problems of today. Rain is harvested in many ways and it is vital supplementary source of water. Diphu is the hilly town, the district headquarter of Karbi Anglong district, Assam, in the north eastern state part of India. The largest administrative district with over population of 61000. Located at an altitude of 186 m (610 ft) has suffered acute water problems, the mismanagement of the town committee, lack of proper knowledge on ground water potential areas has led the people suffered silently , pay a huge sum of money to buy a tank of water. This paper tries to attempt to understand the water scarcity problem’s as well the reason and the rainwater harvesting method practice by the local people. Keywords: water, scarcity, rain harvesting, population increase;

Monitoring and Controlling of Different Process Parameters by Using LabVIEW and Arduino
The design and implementation of process under consideration is done by using LABVIEW software and Arduino Uno. Temperature and level sensors are used to measure temperature as well as level. LabVIEW is used to control temperature and level within set values. The system contains Arduino unit interface in between the PC, the sensors circuit and hardware. Monitoring and controlling of parameter is done using LabVIEW. In general boiler has temperature greater than 200 Degree Celsius, so this is not possible practically to create such environment in laboratory, so a miniature boiler tank model is used where temperature rises up to 150 Degree Celsius. In laboratory model is prepared for measurement of temperature and level measurement with temperature ranges from -55 to 155 deg. C. The LabVIEW monitors and controls temperature, level with set points.
