Our country India is facing some drastic changes in the climatic conditions due to the heating effect caused by various greenhouse gases. The most harmful gas among them is the hydrocarbon family and is increasing at an uncontrolled rate. Hence an effective sensing and communicating system is required. This paper aims in finding out the quantity of the major polluting gas methane. The gravimetric sensor works by absorbing the chemical in a hydrocarbon sponge, which alters the overall mass of the sensing element i.e a cantilever, thereby its resonant frequency. Here a micro-cantilever beam is fabricated using selective Silicon Carbide coatings on the surface to selectively absorb the hydrocarbons. As the gases are absorbed the mass increases and hence there is a change in resonant frequency. This change in frequency gives the measure of the quantity of gas present in that environment. The major expected advantage of this technique would be the repeatability of the sensor that is used.

This paper presents the measuring technique of CO2 gas molecule present significantly in the atmosphere and its alarming rate of increase creates a cause of concern to protect the public and environment from chemical threats, by detecting at an earlier stage accurately and taking the needed action. The development of a MEMS sensor system to detect compounds from a mixture has paved way to the development of small scaled reliable detection systems. The paper provides a novel idea of incorporating a MEMS chemical capacitive sensor element with a monolithically integrated signal conditioning circuit. CO2 gas molecules are sensed using a parallel plate chemical capacitor which uses the adsorption principle. The adsorbed CO2 molecules will form the dielectric media of the sensor thereby changing the overall capacitance of the sensor. This change would in turn provide the quantity of CO2 molecule present. The change in capacitance could be known to us by using a suitable signal conditioning circuit, here a modified schering bridge is considered and the corresponding voltage output gives us the quantity of CO2. This paper provides an overview of the design of the sensor element and the sensing circuit.

In the present investigation, corrosion inhibition of mild steel in acidic solutions has been tested primarily via weight loss tests. Further the test solutions were tested by spectroscopic method as ferrozine as a reagent. By using this method, the corrosion rate of mild steel in various time interval and inhibition efficiencies of leaf and bark extracts of Schleichra oleosa were calculated. Ferrous ion chelating ability of extracts and total phenol content in extracts were calculated using the reagents such as ferric chloride and foloin-ciocalteau reagents respectively. The results of both weight loss as well as spectroscopic methods were found to comparable. The result of the present study has a promising effect in both industrial and day to day livings.Keywords

The Consumer Protection Act enacted in a unique and highly progressive piece of social welfare legislation can only give certain rights to the consumers, but its functioning and implementation largely depends on the awareness and efforts of the consumers themselves. The problem is more acute in the rural areas. To reach the rural consumers, it is crucial to involve the Panchayati Raj institutions in not only educating consumers but also ensuring that fake and spurious products are not promoted in the rural markets. The study aims to the rural people in aspects of creating consumer awareness and also aims to contribution towards consumer protection in Panchayati Raj institutions in Tamil Nadu. The interview schedules were prepared and collected for Panchayati Raj institutions. Rural people of selected sample of 66 villages from five districts were approached and finally 319 respondents were used for analysis. The study reveals that Panchayati Raj institutions in Tamil Nadu have been taken for minimum efforts taking by the rural consumer awareness and need to address the concerns of the rural consumers and the only way to forward is to involve the available constitutional mechanism of Panchayati Raj institutions.Keywords

In this paper the urban heat islands (UHI) effect in Madurai region has been identified by retrieving the land surface temperature (LST) distribution. The aim of this paper is to implement an algorithm to measure land surface temperature in Madurai region and it’s surrounding from Landsat thermal imagery. The Land surface temperature has been estimated by using Single Channel (SC) algorithm and Split-Window (SW) algorithm. These two algorithms can be implemented using Landsat 7 and Landsat 8 satellite data. The various methods adopted for retrieving the algorithm has been addressed in the present study. The results show that for Single Channel (SC) algorithm the error is approximately 1K-2K and in Split-Window (SW) algorithm the error is reduced because as SW algorithm uses two Thermal Infrared (TIR) bands for land surface temperature retrieval. In SW algorithm error is less than 1K. The results show that the LST generated using the SW algorithm was more reliable and accurate. From the final output it is revealed that barren lands, uncultivable land and urban areas experienced high LST and the areas with high vegetation cover and water body experiencing low LST. The results from both the algorithms show a variance of 5-6°C between urban areas, barren lands and vegetation covers thus indicating the presence of UHI in Madurai city.Keywords

Music mood describes the inherent emotional expression of a music clip. It is helpful in music understanding, music retrieval, and some other music-related applications. In this paper, a hierarchical framework is presented to automate the task of mood detection from acoustic music data, by following some music psychological theories in western cultures. The hierarchical framework has the advantage of emphasizing the most suitable features in different detection tasks. Three feature sets, including intensity, timbre, and rhythm are extracted to represent the characteristics of a music clip (the intensity feature set is represented by the energy in each sub band, the timbre feature set is composed of the spectral shape features and spectral contrast features, and the rhythm feature set indicates three aspects that are closely related with an individual's mood response, including rhythm strength, rhythm regularity, and tempo. Furthermore, since mood is usually changeable in an entire piece of classical music, the approach to mood detection is extended to mood tracking for a music piece, by dividing the music into several independent segments, each of which contains a homogeneous emotional expression.
