A Probe on the Status of Microorganisms in the Air, Soil and Solid Waste Samples of Ariyamangalam Dumping Site at Tiruchirappalli District, South India

Abstract: This research contribution is concerned with the microbial occurrence in air, groundwater, soil and solid wastes around a dumping site with an area of about 48 acres located at Ariyamangalam of Tiruchirappalli District, South India. The groundwater and soil samples were collected within a radius of 2 and 0.5 kms respectively. Severe microbial dominance in the groundwater samples was inferred from the MPN per 100 ml of total coliforms. The Karl Pearson correlation was carried out for the total coli forms with the physico-chemical properties of the water samples. The correlation study ascertained the influence of nitrogen and its oxy anions on the growth of microorganisms in operating the biogeochemical cycle. The aero-microbial study conducted at the dumping site registered the survival of six genera each of bacterial and fungal organisms which alleviate the possibility of hazards to the environment and residents’ health. Various harmful and infectious diseases that spread through the microorganisms originated from the dumping site are also discussed in this chapter.

A Study on Attitudinal Hindrances and Human Resource Practices in Empowering Women Construction Workers

Abstract: Construction workers are one of the most numerous and vulnerable segments of the unorganized sector in India. Women construction workers are not treated on par with men construction workers in wages and promotional opportunities, even though they form nearly half of the construction workforce. This study was conducted on 440 men and 440 women construction workers to find out the factors affecting their wages, the willingness of men workers to train and employ women construction workers as skilled workers, and the willingness of women construction workers to become skilled workers. The findings of the study show that there is a large discrimination in wages and also in promotion of women when compared to men. It has been found that most of the women construction workers, especially workers from rural areas, and literate and young women, are willing to be trained to become skilled workers (masons). The study also reveals that men construction workers, especially from urban areas, are willing not only to train but also give placement to them.

Mining Efficient Fuzzy Bio-Statistical Rules for Association of Sandalwood in Pachaimalai Hills

Abstract: The integration of association rules and correlation rules with fuzzy logic can produce more abstract and flexible patterns for many real life problems, since many quantitative features in real world, especially surveying the frequency of plant association in any region is fuzzy in nature. This paper presents a modification of a previously reported algorithm for mining fuzzy association and correlation rules, defines the concept of fuzzy partial and semi-partial correlation rule mining, and presents an original algorithm for mining fuzzy data based on correlation rule mining. It adds a regression model to the procedure for mining fuzzy correlation rules in order to predict one data instance from contributing more than others. It also utilizes statistical analysis for the data and the experimental results show a very high utility of fuzzy association rules and fuzzy correlation rule mining in modeling plant association problems. The newly proposed algorithm is utilized for seeking close associations and relationships between a group of plant species clustering around Sandalwood in Pachaimalai hills, Eastern Ghats, Tamilnadu.

Digital library for mulsemedia content management

Abstract: Digital Libraries are key infrastructure for document management. Until now, these documents have included multimedia objects such video, images, text, sounds. In this paper, we focus on enhanced sensorial media content management in Digital Library. Enhanced sensorial media content combines the sense of touch with other media. All mulsemedia content management requires new methods, starting from the source through storage to delivery. Digital libraries have to use all modern technologies in order to supply services of a high quality. As these efforts mature, the research emphasis is shifting from issues surrounding the development of digital library infrastructure and collections to understanding the impact of mulsemedia collections and services to users and related communities. The major consequence is that digital libraries are more and more built as enterprise knowledge ecosystem. In this paper we review the development in the field and points out the challenges of digital library for mulsemedia content management.

Electrochemical oxidation of cinnamic acid using stainless steel electrodes

Abstract: The electro-organic technique is observed to be the modern tool in achieving the oxidation of organic acids to some other useful organic molecules. In the present study, the favourable experimental conditions for carrying out the electrochemical oxidation of cinnamic acid, the experimental set up required and probe for the various products formed have been tried. The anodic process has been carried out at low cost and readily available stainless steel electrode undar aqueous conditions. On identification of the products using chromatographic and spectroscopic techniques, the most probable mechanism has been proposed. To confirm the positive occurrence of the oxidative process under electrolytic conditions, the current — potential study was carried out. The product was analysed by TLC technique, UV and IR spectral studies and identified as 1,4-diphenylbut — 1,3-diene. This work paves a humble way of opening up a new area wherein other electro analytical parameters like polarography, cyclic voltammetry, electrode variation, temperature variation, solvent effects etc. can be studied, along with innumerable substituent effect studies.
