Abstract: MNREGA is playing pivotal role in the Rural development. It has changed the income and expenditure status of rural poor. It is casting significant impact on the Economic condition of the rural people and changing their socio-economic status. MNREGA is a demand driven employment programme for manual unskilled workers. It involves a paradigm shift from all other programmes launched in the past, since it provides a guarantee of employment for at least 100 days in a year. In the block of Lauriya, the impact of this programme is positive as far as prevailing wage rates are concerned. The wage rates for farm and non-farm labourers went up and the incomes of the poor households have increased. The expenditure pattern indicates that such households are now spending on a variety of items and that the socio-economic status of the unskilled labourers has improved to a great extent.

Keywords: Socio-economic indicators, MANREGA, income and expenditure.

Abstract: Cracks can form due to fatigue or they can exist as a consequence of manufacturing processes such as deep machining marks or voids in welds and metallurgical discontinuities such as foreign particle inclusions. Nucleation and propagation of cracks caused by repeated cyclic loading below the yield stress of a material may cause catastrophic failure. As the crack forms and grows under cyclic loading, the residual strength and residual fatigue life decreases. In the present study, relevant analytical, experimental and numerical methods are used for predicting the ultimate strength and residual fatigue life of a cracked steel plate element under axial tension, where cracking damage is treated as a parameter of influence is studied. In fatigue life estimation process of cracked steel plate element, Linear Elastic Fracture Mechanics (LEFM) is introduced to describe and predict fatigue crack growth life and fracture under the basic assumption that material conditions are predominantly linear elastic during the fatigue process. The objective of this analysis is to predict crack growth, residual strength and residual fatigue life for the given initial damage on Critical Structural Element (CSE). Information on the growth of cracks in engineering structures and the residual strength of cracked structures is necessary for prediction of service lives of structures subjected to fatigue loading and for the establishment of safe intervals.

Abstract: Superoxide Dismutases (SOD) are metal-containing, antioxidant scavenging enzymes that detoxify the reactive oxygens by catalyzing the dismutation of superoxide radicals to oxygen and hydrogen peroxide. SOD exists in virtually all oxygen respiring organisms and has been proposed to be important for stress tolerance during environmental adversity. SOD metabolize Reactive Oxygen Species (ROS) into a safe product, and hence prevents cellular damage. Fishes are exposed to daily and seasonal fluctuations in oxygen availability. Study of the histological activities of SOD in Labeo rohita shows significant differences among different tissues types and in response to change in the content of dissolved oxygen from different experimental sites. Results also suggest that the total SOD activities positively correlated with the content of dissolved oxygen in the water samples.

Keywords: Superoxide dismutases, Labeo rohita , dissolved oxygen, reactive oxygen.

Abstract: Field-programmable gate array is an integrated circuit design to be configured by a costumer or a designer after manufacturing. This paper outlines the transformation of events, development, reproduction, and land use of FPGA (Xilinx Spartan-3E X3S500E) the use of other NSSP equivalent calculations (one source of very limited method with loads of non-contradictory edges). Its operating time has a high O-m (min (n, ε)), and uses mechanical properties in the O (m) application, a good place to guess. It has been used in standard bench extraction cases and its presentation is comparable to the use of the fast-paced wide-ranging cases of Digital - O (m + n log n) calculations. In the case of practical problems, a calculation of the required deflection is required in the application for clock cycles repeated 200-300 times. The use of mechanical devices is completely unchanged, and the paper proposes the design of a second-year chip, which, when made, will allow the gadget to produce mechanically and reproduce continuously. The general flexibility of the chip combined with its capacity and flexibility makes it understandable in the broad integration of the research center and field conditions. In addition, the basic calculation is the result of another global equity analysis, which will be called "delayed acceleration" because it depends on the control and recording speed of the equally increasing signals in an organization. This global perspective tends to address a wide range of issues that are far more serious than roadmap, including the NP-complete subset aggregate and Hamiltonia road issues. A quick plan to address the first of these problems is developed as part of this work and is proposed immediately in the discussion.

Abstract: In India, most of plastics waste is abandoned and not recycled. This situation causes serious problems such as wastage of natural resources and environmental pollution. Solid waste management is one of the major environmental concerns in the world. In fact, a wide variety of waste materials can be utilized as inert in a cement matrix. In this study, plastic waste in the form of water-pouch (distilled water industry) and artificial sand both materials were used as a partial replacement of fine aggregates in a concrete mix. The aim of this study is to investigate the fresh and hardened concrete properties of the newly defined concrete mix. The mix was obtained for a varying percentage of plastic waste and artificial sand by 5, 10, 15 and 20 percent by weight of natural sand requirement. Result showed there was considerable improvement in compressive strength and workability up to 10 percent of replacement. The use of such concrete mixes in light weight concrete will considerably reduce the solid waste produced by plastics.

Abstract: The different component of air may have important effect on the health of man and animals, both individually and through their interactions. The present investigation was carried out to monitor the occurrence of indoor aeromycoflora at two different sites of Nagbhid during June 2013 to May 2014. Air sample was collected at each site twice in a month by exposing petriplates containing Potato Dextrose Agar (PDA). Total 498 colonies were recorded. The fungal colonies were asses on the basis of micro and macro morphological characteristics. Winter season favors the occurrence of more fungal colonies. In this investigation, the predominant fungi observed were Aspergillus niger (18.29%), A. flavus (11.04%), A. fumigatus (7.23%), Curvularia lunata (6.83 %), Cladosporium spp. (6.43%).The rainfall (mm), temperature (ºC) and relative humidity (%) was noted and occurrence of fungi was correlated with these meteorological factors.

Abstract: Friction Stir Spot Welding (FSSW) is a non-fusion welding process which creates a metallurgical bond between two specimens. Since Resistance Spot Welding (RSW) has many disadvantages including high wear rate of electrode and the welding of materials using this RSW technique generates high amount of heat in the specimen and it also cools rapidly, due to this rapid cooling the material becomes brittle at that welded area and thus reducing the physical properties of the material, due these effects FSSW has been selected to weld AA3102 and Carbon Steel 1010. FSSW is governed by three process parameters which include, Tool Rotational Speed, Dwell time, Load. In this work the effect of process parameters on joint strength has been studied based on experimental and numerical results. The Taguchi method is selected as a tool to identify the optimized process parameters for welding AA3102 and Carbon Steel 1010. The experiments conducted as a combination of the process parameters were made based on the result given by the Taguchi orthogonal table. The Taguchi method uses Signal to Noise ratio (S/N ratio) to determine the effective process parameter. The specimens that are welded using these parameters were tensile tested and with the help of the results obtained the Taguchi analysis is done and the parameters which will yield the maximum strength is obtained.

Abstract: The present air cooling methods are evaporative coolers, air conditioning, fans and dehumidifiers. But running these products need a source called electricity. The producing of electricity is ultimately responsible for hot and humid conditions i.e. global warming. In hot and humid conditions the need to feel relaxed and comfortable has become one of few needs and for this purpose utilization of systems like air-conditioning and refrigeration has increased rapidly. These systems are most of the time not suitable for villages due to longer power cut durations and high cost of products. Solar power systems being considered as one of the path towards more sustainable energy systems, considering solar-cooling systems in villages would comprise of many attractive features. This technology can efficiently serve large latent loads and greatly improve indoor air quality by allowing more ventilation while tightly controlling humidity. Despite increasing performance and mandatory energy efficiency requirements, peak electricity demand is growing and there is currently no prevalent solar air cooling technology suited to residential application especially for villages, schools and offices The functionality of solar powered cooler is dissimilar as that of traditional coolers. The solar energy is stored in battery in the form of an electrical energy by photovoltaic effect. This battery is in turn connected to solar cooler power source. Then the converted energy is used to run the centrifugal fan. This fan covered with cooling pads, through which water is passed at a specific rate. As the fan sucks the hot air through cooling pads, heat transfer occur between air and water thus generated cool air enters into the room. It do not creates the overheads of maintenance or purchasing of pump neither it has to be sent for servicing every season. The concept of solar powered air cooler sounds good and economical; hence almost every class of our society can bare its expenses.

Abstract: Automation and Technology play a very big role in human life; we can't imagine our life without automation. Then how can Livestock/ cattle live without these technologies. In north-western region of Rajasthan temperature goes varies high in summer days (approx 50o C). This high temperature affects livestock/ cattle health. It reduces milk yields. This affects livelihood as well as economy. There are many projects developed to avoid these types of critical situations using technologies like embedded-based, wireless sensor-based, IOT based. In this temperature-based cooling system for livestock and cattle farm in the western region of Rajasthan using Arduino system, the wireless temperature sensor senses the environmental temperature of cattle/ livestock shed and if the temperature goes high then the cooling system Fogger system start and when the temperature goes low then the fogger system goes off automatically. This system is controlled by Arduino. The temperature is also displayed on LCD display. And the owner can set the threshold value of high-low temperature using mobile communication through Bluetooth.
