Assessment of Nitrate Contamination in Ariyalur District, Tamil Nadu (India)
Groundwater pollution has been reported in many aquifers because of high concentration of nitrate which is the result of excessive use of fertilizers to crop land. Systematic sampling was done, with a view to understand the source of nitrate concentration . 100 sample sites were selected and the samples were taken for a baseline study to understand the geochemistry of the study area and to assess its physicochemical characteristics. The water quality parameters were investigated for pre-monsoon (January 2011) and were compared with the standard values given by ICMR / WHO. The hydrochemical data of 100 samples indicates that the concentration of almost all parameters fall within the permissible limits expert nitrate. Linear Trend Analysis on seasonal basis clearly depicted that nitrate pollution in the study area is increasing significantly. None of the samples during the samples during pre-monsoon season were showing a high concentration of nitrate, exceeding permissible limits of WHO (50 mg /l), which is due to the use of nitrogenous fertilizer in the study area. Appropriate methods for improving the water quality and its management in the affected area have been suggested.

Analysis of FM/FM/1 Queuing System with Pentagon Fuzzy Numbers and using DSW Algorithm
This paper intends a method to construct the membership functions using DSW algorithms for the performance measures in queuing systems where the arrival rate and service rate are fuzzified. The performance measures of FM/FM/1 are analyzed mathematically using pentagon fuzzy numbers, and by applying DSW (Dong, Shah & Wong) algorithm where the arrival rate and service rate are fuzzy numbers. To determine the validity of the proposed approach numerical example is illustrated.

Partial Replacement of Cement with GGBS in Concrete
In this present construction era concrete is the mostly used construction material in the world. Concrete is consumed widely that it is second most consumed material after the water in terms of per-capita consumption. As the pollution is increasing and the environmental sustainability is affected, researchers are seeking for other materials to reduce the consumption of cement. GGBS is one of these supplementary materials used to replace with cement to reduce the consumption of the cement.

Effects of Glass Powder and Brick Aggregate in M-25 Concrete
Concrete is a mix of bond, sand, coarse total and water. The key factor that increases the value of cement is that it can be intended to withstand harshest situations critical part. Today an unnatural weather change and ecological decimation have turned out to be show hurts as of late, worry about natural issues, and a changeover from the mass-squander, mass utilization, large scale manufacturing society of the past to a zero-radiation society is currently seen as noteworthy. Typically glass does not hurt nature at all since it doesn't radiate contaminations, however it can hurt people and additionally creatures, if not managed precisely and it is less benevolent to condition since it is non-biodegradable. In this way, the improvement of new advancements has been required. The term glass contains a few compound assorted varieties including pop lime silicate glass, salt silicate glass and boro-silicate glass. To date, these sorts of glasses glass powder have been broadly utilized as a part of concrete and total blend as pozzolana for common works. The supportable development idea was acquainted due with the developing worry about the eventual fate of our planet since development industry is an immense buyer of normal assets and, at the same time, a waste maker. Concrete blocks industry is viewed as one of the greatest normal asset buyers. In any case, it might be utilized as a potential place for reusing squanders, in view of its composite nature (i.e., bond, water and totals). Totals in strong bond blocks contain around 60– 75% of the aggregate volume, so any lessening in characteristic totals' utilization will have huge effects. Reusing of squanders as regular totals is monetarily suitable as well as it is considered as an ecological amicable approach. Mud blocks are generally utilized as a part of Egypt. The amount of stone work annihilation squander is assessed to be around 2– 3 and 1.5 times higher in structures with stack bearing workmanship and fortified cement surrounded brick work infill as basic frameworks, individually. As needs be, a critical part of decimation squanders is earth blocks. Also, block fabricating industry creates extensive amounts of rejected let go blocks due to being off-standard (i.e., broken, mutilated, under consumed, or over consumed). The off-standard blocks are sold for arranging purposes, if monetarily possible, yet generally dumped into destinations around the block industrial facilities causing natural issues. Consequently, the reusing of squashed blocks as option totals has a specific enthusiasm as it can impressively lessen the issue of waste stockpiling and then again can help in the conservation of characteristic totals. Besides, concrete containing coarse smashed blocks had a generally bring down quality at early ages than typical total cement. This is because of the higher water ingestion of pounded block totals contrasted with regular totals.

Automated Safety Control Blind Zone Alert System
This paper presents in modern vehicles many number of sensors are used for different applications and also these sensors requirement increases in future, intra-vehicular wireless sensor networks (IVWSNs) have introduced in the automotive industry. This generation vehicles required advanced technology for controlling vehicle to provide safety and as they will able to reduce the amount of wiring harness inside a vehicle. By avoiding the usage of wires in vehicle, vehicle weight will reduce, then engine performance, fuel economy and reliability will improve. These advantages on an IVWSN is a flexible platform, and these can support other vehicular applications as well. And the implementation of IVWSN system of cheaper when compared to systems that are using cameras, or radars.

Synchronization of Photovoltaic Systems in Single-Phase Grid-Connected Under Grid Faults
The highly increasing penetration of single-phase photovoltaic (PV) systems pushes the grid requirements related to the integration of PV power systems to be updated. These upcoming regulations are expected to direct the grid-connected renewable generators to support the grid operation and stability both under grid faulty conditions and under normal operations. Grid synchronization techniques play an important role in the control of single-phase systems in order to fulfill these demands. Thus, it is necessary to evaluate the behaviors of grid synchronization methods in single phase systems under grid faults. The focus of this paper is put on the benchmarking of synchronization techniques, mainly about phase locked loop (PLL) based methods, in single-phase PV power systems operating under grid faults. Some faulty mode cases are studied at the end of this paper in order to compare these methods. It is concluded that the Enhanced PLL (EPLL) and the Second Order Generalized Integrator based PLL (SOGI-OSG PLL) technique are the most promising candidates for future single-phase PV systems due to their fast adaptive-filtering characteristics.
