 Abstract

The present study aims to assess feasibility of tea leaf waste as potential adsorbent for defluoridation of potable water. The present work involves batch adsorption technique using SPANDS method to infer optimal values of different adsorption parameters such as adsorbent dose, pH, contact time, stirring rate and adsorbate dose for acid and alkali treated tea leave waste. The optimum sorbent dose was found to be 2.0 g/250 mL, equilibrium was achieved in 90 minutes at 120 rpm and enhanced adsorption was obtained at pH 2 for both acid and alkali treated tea waste. Maximum fluoride removal was observed to be 84.8% for acid treated tea waste and 66.8% for alkali treated tea waste at optimum conditions.

 Abstract

Roller conveyor chains are mostly preferred in production or assembly lines to transport goods as a material handling system. Roller chains have to deal with different environment conditions, chemicals. This causes wear and tear of components of chains and hence unexpected failure and costly production. In resent work I have studied the material EN 48, EN 353 and SS 304 of bush of roller conveyor chain under different loading conditions.

 Abstract

The tribal students are the one with least exposure to the external world and with least facilities available to them but with a maximum support of their family and a healthy open environment to live in. With that situation, it would be worthwhile to check the social intelligence of these students in comparison to the non-tribal students. The present piece of research was done by studying a sample of 300 tribal students selected randomly from Kashmir provision and compare them to an equal number of those students who are not essentially tribal i.e. Non-Tribal. The Social intelligence scale by Chadda and Ganesan (2009) was used for the measurement of Social intelligence. The results after analysing the data revealed that the non-tribal students were having high patience, cooperativeness, confidence, social environment, tactfulness and sense of humour while tribals were high on sensitivity dimension of social intelligence. On memory dimension of social intelligence, no significant difference was seen between the two. Also, a significant difference was found between tribal and non-tribal students on the composite score of social intelligence with non-tribals having higher social intelligence than tribal students.

 Abstract

Data mining is the process of discovering interesting knowledge patterns from large amount of data stored in database. It is an essential process where the intelligent techniques (i.e., machine learning, artificial intelligence, etc) are used to extract the data patterns (i.e., features). The aim of data mining process is to extract the useful information from dataset and transform it into understandable structure for future use. Feature extraction is the process of extracting the relevant features from large database for dimensionality reduction. Many conventional feature extraction techniques were used to project the data in low dimensional space to highlight the property of scattered data. But, the feature extraction time and feature extraction accuracy performance was not improved for high dimensional dataset. Our research objective is to extract the feature from high dimensional data with higher feature extraction accuracy and minimal space complexity by studying the existing issues.

 Abstract

In the present study phytosociological analysis of Low land ecosystem require knowledge of standard phytosociological methods and its component species. The standard phytosociological methods were applied to the plant communities of Varansai was carried out one at crop land site namely site I and other at low land site namely site II. The total number of plant species recorded from both the sites is in all 29 species. The total number of species recorded at two sites separately was 20 and 22 respectively. On the basis of IVI and frequency data some species as Ammania baccifera, cynodon dactylon, cyperus rotundus, Melilotus alba were found to dominate at site I, whereas that for site II was exhibited by Ammania baccifera, cyperus rotundus, chenopodium album, eclipta alba. Study of species composition of both sites reflects that the area occupied by Ammania baccifera L. is greater than any other studied species. It exhibit higher value of IVI and frequency than other species shows its high competitive ability presence of different interference mechanism including root system and foliar structure may be accounted for possible reason for dominance of Ammania baccifera L. in Low land ecosystem of Varanasi.

 Abstract

Fruits are the most important food for mankind as they play a major role in maintaining good health by enhancing the immune system. In general fruit harvests are spoiled due to improper quality control activity. So they are preserved by fermentation process in the form of wine. Wine restores most of the nutrients present in the original fruit juice. The nutritive value of wine is increased due to release of amino acids and other nutrients from microbial fermentation. The most commonly used fruit for wine production is grape. Guava, cheekoo, plums, cherries, black berry, peaches, pears also have the ability of producing wine. Of which, guava and cheekoo are easily available seasonal fruits. They are the powerhouse of minerals and vitamin and they have antioxidant properties. The objectives of the study are to make a comparative account of nutrient rich home-made wines, to identify their phytochemical components and to determine their antimicrobial activity against members of Enterobacteriaceae family.

 Abstract

Wire electrical discharge machining allowed success in the production of newer materials, especially for the aerospace and medical industries. Using WEDM technology, complicated cuts can be made through difficult-to-machine electrically conductive components. The high degree of the obtainable accuracy and the fine surface quality make WEDM valuable. Inconel is one of the newer materials that are developed to be hard, strong and temperature resistant which is widely used in turbo machinery industry due to their outstanding mechanical properties. However the challenge lies in optimum performance of WEDM and machining constraints with Inconel-718, so in this paper Inconel 718, was machined using WEDM and further with two different electrodes materials zinc coated brass and plain brass. Anova, is used to get the most influencing parameter out of discharge energy, pulse off, wire feed, wire tension, and flushing pressure on cutting rate, accuracy parameter kerf width. It has been found that discharge energy released is determining factor for both the response variables and there is considerable effect of electrode materials.

 Abstract

Pollution is a major cause of concern affecting not only the nature but also the food we consume. In a recent study high concentrations of heavy metals like arsenic, nickel, cadmium and lead were found in aquatic life (fish samples obtained from various outlets in Hyderabad and Secunderabad ).The concentration of heavy metals depend on the fish species. Presence of heavy metals in these fish is an issue of pollution of water bodies , which is of major concern .Hence there is a need to know the concentrations of heavy metals in water . In the present study an attempt was made to analyse the concentrations of arsenic ,nickel, cadmium and lead by atomic absorption spectrophotometry. Water naturally contains a few heavy metals but their concentrations are low and the high concentrations are due to pollution
