Influence and Effects of Industries on Geochemical Behavior of Heavy Metals in Soil

D.Shiva Kumar andS.Srikantaswamy

Metals are considered as important toxic pollutants and there is extensive literature concerning their accumulation in ecosystems. Metals are continuously released into the biosphere by natural processes like volcanoes, weathering of rocks and also by various anthropogenic activities, such as mining, combustion of fuels, industrial and urban sewage and agricultural practices. On a global scale there is now abundant evidence that anthropogenic activities has polluted the surrounding environment with heavy metals from the poles to the tropics and from the mountains to the depths of the oceans. Once metals are introduced and contaminate the environment, they will remain. Metals do not degrade like carbon-based (organic) molecules. The only exceptions are mercury and selenium, which can be transformed and volatilized by microorganisms. However, in general it is very difficult to eliminate metals from the environment. Traditional treatments for metal contamination in soils are expensive and cost prohibitive when large areas of soil are contaminated. In this present studies on metal pollution in industrial area of Mysore city has been taken. Also, metal speciation, bioaccumulation in biota, as well as abiotic and biotic factors affecting their bioavailability, and ecological effects of heavy metal pollution will be studied. The geochemical behaviour of heavy metals were analysed through speciation studies. Studies show that the metals mobility is less in the heavy metals mobility is little low in the Exchangeable metal fraction and Carbonate bound metal fractions. But in the Fe– Mn oxide metal fraction and Organic and sulfide metal fractions mobility of the metals is comparatively little higher than the other fraction. The final residual metal fraction has the total remaining metal content in the sample In this study period, the industrial surrounding area soil has lost their natural fertility with the addition of some heavy metals by physico-chemical analysis.

To Study the Domestic As Well As Community Storage Systems With Respect To Quality of Water and Health Status of the Common People

M.A.Jane and S.P.Ingole

This study has investigated domestic as well as community storage system with respect to quality of water & health status of common people. The type of storage container & hand contact with stored drinking water has been associated with increased incidence of diarrheal diseases. There is also circumstantial evidence of linking such factors as the sanitary conditions in the domestic environment, cultural norms & poverty with the pathogen load of household stored drinking water & hence the risk of diseases transmission. Drinking water provision indicated that the community was exposed to water related health risk when consuming the water supplied. The study indicated that although the public water supply was of good quality, the stored water, once fetched from the standpipes, deteriorated the quality which often was not safe for human consumption.
Monthly water samples were collected from containers kept inside the houses & overhead tanks of selected families. Parameters were analyzed mainly TDS, sulphates, chlorides, hardness, residual chlorine, biological parameter (MPN). The reason for the deterioration varied from poor container hygiene & open containers subjected to environmental pollution, to the manner of handling of water by individuals in households. 

Using Back-Propagation Recognition of Facial Expression

Neeraj Shukla and Anuj Kumar

Neural networks, with their remarkable ability to derive meaning from complicated or imprecise data, can be used to extract patterns and detect trends that are too complex to be noticed by either humans or other computer techniques. A trained neural network can be thought of as an expert in the category of information it has been given to analyse. Concerning image processing it is very interesting to recognize the human gesture used for general life applications. For instance, observing the gesture of a driver when he/she is driving and alerting him/her when in sleepy mood will be quite useful. Human gestures can be identified by observing the different movements of eyes, mouth, nose and hands. Here we are focusing on the human face for recognizing expression. Many techniques are available to recognize face. This paper planned facial expression recognition using back-propagation of neural network. The procedures are image capturing, face detection, filtering, facial feature extraction and recognition using neural network. The proposed method can recognize the facial expression from image captured well.

Rajneesh Kakar and Shikha Kakar

The aim of the present paper is to investigate the surface waves in a nonhomogeneous, isotropic, viscoelastic solid medium of nth order including time rate of strain. The theory of generalized surface waves has firstly been developed and then it has been employed to investigate particular cases of waves, viz., Stoneley, Rayleigh and Love type. The wave velocity equations have been obtained for different cases and are in well agreement with the corresponding classical result, when the effect of viscosity, magnetism as well as non-homogeneity of the material medium are ignored.

Land Record Computerisation a case study in reference to Chomu Tehsil, District, Jaipur (Rajasthan)

Vinod Kumar Agrawal and Sukhveer Saini

Rajasthan state economy is based on agriculture. In the state, land holding is very small. Most of the farmers are either small or marginal. Land records constitute vital element both in anti poverty strategy and for modernization. Majority of our people are under its direct control by way of their possessing even a small piece of land. Historically Land Records Administration is one of the oldest and traditional Government departments. Patwari at village level maintains record of land. With the traditional way of working and record storing, searching and updating has increased manifold and these methods have become inadequate to cope up with the situation. Basic record of ownership details are maintained in Jamabandi. Land transaction is a regular phenomenon. Today one piece of land owned by one, tomorrow it may be with other. The legal transformation of land takes place by mutation. Based on mutation, transactions are marked in Jamabandi where it affects the ownership. As per the act, one fourth of total villages of each tehsil, new Jamabandis are written every year by rotation, which is quite cumbersome & time consuming. The enormity of the problem can be ensured by the fact that majority of tenants are not much literate and do not know of anything until the time their land rights are jeopardized. Therefore, to bring efficiency into the system computerization needed and it has naturally a direct and immediate impact on majority of the people, particularly rural population. A Pilot project for land record computerisation was started in Jaipur and Barmer district of Rajasthan in 1995. Later on, it was implemented in all the tehsils of the state. A case study was conducted of Chomu tehsil to know the status of Land Record Computerisation in the month of August 2012.

Thimme Gowda P., Manjunaththa S. B., Yogesh T. C. and Sunil A. Satyareddi

Appropriate strategies for planning and management of irrigated farmland. One of the major practices adopted by the researchers for estimating water requirement of crop is modelling. For determination of crop evapotranspiration and yield responses to water, CROPWAT model is used, which was developed by the Land and Water Development Division of Food Agricultural Organization (FAO). It includes a simple water balance model that allows the simulation of crop water stress conditions and estimation of yield reductions based on well established methodologies. An experiment to study water requirement of maize (Zea mays L.) for under rainfed condition at Dharwad was conducted during kharif season of 2011 in field deep black soil at Main Agricultural Research Station, Dharwad. The field experimental data with the two dates of sowing of maize i.e June 16, 2010 and July 30, 2010 were collected and analyzed. The total water requirement of maize sown at an early date was 116.0 mm and that of sown at late date was 183.8 mm. As a result, the water demand was more as compared to early sown maize. Therefore, water requirement of maize varied with planting dates. 

Water Status and Problems in India

C. P. Kumar

The surface water and groundwater resources of the country play a major role in agriculture, hydropower generation, livestock production, industrial activities, forestry, fisheries, navigation, recreational activities, etc. Traditionally, India has been an agriculture-based economy. Hence, development of irrigation to increase agricultural production for making the country self-sustained and for poverty alleviation has been of crucial importance for the planners. The rainfall in India shows great variations, unequal seasonal distribution, still more unequal geographical distribution and the frequent departures from the normal. In view of the existing status of water resources and increasing demands of water for meeting the requirements of the rapidly growing population of the country as well as the problems that are likely to arise in future, a holistic, well-planned long-term strategy needed for sustainable water resources management in India.

Pallavi.H.V, Srikantaswamy.S, Kiran B.M, Vyshnavi.D.R and Ashwin.C.A

This study aims at converting these agricultural wastes to char, by an ecofriendly, continuous batch process. The char thus obtained can be briquetted into a solid fuel form and later can be used as an efficient, clean source of fuel. Therefore, bagasse and coffee husk selected as a raw material for the carbonization that helps in mitigating both economic and environmental problems. Results obtained shows that the calorific value of briquettes produced from bagasse and coffee husk found to be 10439 KJ/Kg and 11389 KJ/Kg respectively. The briquette produced from the mixture of bagasse and coffee husk in the ratio 3:1 had a calorific value of 11126 KJ/Kg. Briquettes produced from coffee husk have greater calorific value. The calorific value of wood charcoal was found to be 8269 KJ/Kg, which is lesser, compared to the briquettes produced. Hence, briquettes have better physical properties and combustion rate than the initial waste. Production of briquette charcoal helps to ease the pressure on the forest cover, there by solving the deforestation problem. 

A Study on Utilization of Groundnut Shell as Biosorbant for Heavymetals Removal

Kiran B.M, Srikantaswamy. S, Pallavi H.V, Manoj .V and Tahera Tasneem

This work includes the utilization of groundnut shell, which is a low cost biosorbent for the removal of heavy metals from aqueous solutions. Biosorption is a process that utilizes low-cost biosorbents to sequester toxic heavy metals. Biosorption has distinct advantages over the conventional methods, which include reusability of biomaterial, low operating cost, selectivity for specific metal, short operation time and no chemical sludge. The mechanism of biosorption is complex, mainly ion exchange, chelations, adsorption by physical forces, entrapment in inter and intrafibrilliar capillaries and spaces of the structural polysaccharide network because of the concentration gradient and diffusion through cell walls and membranes. Equilibrium studies and kinetic studies conducted by varying parameters like pH, dosage, concentration. , it was observed that for a contact period of 12 h, the removal efficiency and specific uptake of Cu (II) depends on type and quality of the biosorbent. The percentage removal of Cu (II) using groundnut shell powder as a biosorbent of varied amount from 5 to 50 g/L was 30.4% to 68.2%. This shows that with the increase in concentration of biosorbent, the removal efficiency also increased. Further increase for dosage beyond 50 g/L, there was a negligible increase in percentage removal.

Electro Kinetic Potential Technique for Ore Beneficiation of CaCO3

Raghu Babu, K. and Ragaranjan, D.K.,

Electro Kinetic Potential technique also called zeta potential technique is one of good methods for ore beneficiation. In this method, the required ore material is kept at Electro Kinetic potentials by adding respective chemical to maintain pH. The CaCO3 is kept at electro kinetic potential of pH 9.5 by adding NaOH, which makes the other impurities to attain ionization. This solution is passed through anion and cation resins. The metal impurities of pH less than 9.5 will be trapped in the resins by ion exchange principle and the neutral CaCO3 will be passed along with the solution. Dewatering is done by membrane filtering and pressing techniques. The saturated resin beds can be reactivated and reused.
