Soil resources of the coastal region of Cuddalore district of Tamilnadu were evaluated to assess the productivity rating for field crops, pastures, agroforestry, forestry and other tree crops. The soil resources were inventoried using remote sensing approach. The IRS 1D PAN merged LISS III data at 1:50,000 scale was used for pre-field interpretations. The soils mapped were evaluated for its productivity for agricultural, pasture, agroforestry, forestry and other tree crops. The texture of the soils varied from sandy to clayey due to the coastal sand dune landforms (72%). Loam (Arasanatham, Srinivasapuram and Mangadu series) and clay soil (Kondal series) occupied 16 and 3%, respectively which falls under alluvium landform. The mean pH of the soils ranged from 6.79 to 8.29. The neutral soil phase (6.5 to 7.5) was recorded in Mahabalipuram, Vandiyampalayam, Padugai, Pulavanur and Arasanatham series which occupied 58% (4905 ha) of the study area. The remaining soil series exhibited alkaline pH ranging from 7.85 to 8.29 (3688 ha; 42%). The study revealed that 71, 16 and 3 % of the area falls under Entisols, Inceptisols and Veritsols, respectively.Keywords

This research work was aimed to study the spatial and temporal changes in groundwater quality of the coastal region of Cuddalore district, Tamil Nadu. The study was conducted during 2006 for which the coastal area was divided in to three zones based on 1.5 km spatial distance from sea. The groundwater was collected from 27 representative shallow wells for the whole year with three-month interval representing different seasons. The water samples collected were characterized for its chemical composition as well as electro-che mical properties. Based on the chemical composition, different quality parameters were arrived. The results revealed that 88 per cent of the wells recorded for slightly alkaline pH ranging from 7.6 to 7.9 with electrical conductivity varying froml.l to 4.0 dS m-1. The sodium and magnesium hazard was higher in most of the wells. Seawater intrusion is the key factor, which decides the quality of groundwater in this coastal zone. Natural rainfall is the next most important factor which balances the negative effects of seawater intrusion. In total, the grolIDdwater quality of this coastal zone was poor during swnm.er and optimum during monsoon and post monsoon seasons which necessitates that sufficient care may be taken when using this water for agricuJtura1/agroforestry/fOrestry/other land use purposes.Keywords

Anomalous origin of left coronary artery from pulmonary artery is a rare congenital coronary anomaly which usually becomes symptomatic in infancy. However, in few cases due to extensive collaterals from right coronary artery, they remain asymptomatic till adult life. Later they may present in cardiac failure, arrhythmias or sudden cardiac death. We present here a 52 year old female who came in cardiac failure and on evaluation was found to have this coronary anomaly. She was referred for surgical correction.Keywords

Road extraction is one of the major problems in cartographic feature extraction. High-resolution satellite imagery provides an important data source for road extraction. This paper deals with road extraction from high resolution satellite imagery using level set method. In the proposed method, the high resolution satellite image is first preprocessed using non-liner anisotropic diffusion to enhance the road boundaries and to smooth the image. In the next step level set method is used to extract the roads or road network. The method is tested on high resolution satellite imagery such as IKONOS and Quickbird.Keywords

Mobile phones are playing a vital role in our life. As wireless communication has been rapidly advanced, mobile applications and services are becoming more and more popular, like instant messaging, downloading of a variety of contents, mobile commerce, mobile banking, and information searches. Mobile devices such as cellular phone, PDA and smart phone are exposed to numerous security threats like malicious code (including virus, worm and Trojan horses), vulnerabilities of mobile phone, attacks on communication, data robbery and damage and mobile spam. For voice communications, the introduction of security has been significantly slower. The main reason has been technological limitations.
The current protocols for wireless communication for either placing or receiving a call requires both MIN (Mobile Identification Number) and ESN (Electronic Serial Numbers) to be broadcasted between Wireless telephone and MSC (Mobile Switching Center). While doing so it is important to protect the Pair MIN and ESN,because they can be easily intercepted and can be illegally programmed. So we need a strong authentication mechanism toprotect the pair (MIN, ESN) and need an improved security system toprotect against unauthorized use of wireless communications.
The paperemploys the user’s finger print to authenticate the agents of wireless communication. By using finger prints it guarantees a strong authentication mechanism. Also it avoids maximum fraudulent case. The proposed system involves using atoken generated from biometric information, the user’s personal fingerprint as the secret key in the context of a “challenge-response” scenario. This system includes Finger print capture Module and acentral authentication system coupled to a Mobile Switching Centre. The Finger Print Capture Module uses the “Minutia Algorithm” andthe “Pattern Matching Algorithm” to record and retrieve the finger prints.
When a communication is initiated the Central Authentication system engages the “Challenge-response” authentication. It checks whether the user’s fingerprint entered through the Fingerprint Capture Module matches with the information sent from the Central Authentication System. Only if it matches the call is connected otherwise the call is denied. This virtually eliminates all, of thedrawbacks of the existing system.

A field experiment to study the soil, plant nutrient status and yield of hybrid chilli (Capsicum annuum L.) CCH1 as influenced by fertigation of N and K fertilizers was carried out during 2010-12. The experiment was laid out in Randomized Block Design with three replications and the treatments included were three levels (125, 100 and 75 % recommended dose) each of water soluble and straight fertilizers. The soil nutrient parameters viz., available soil nitrogen, phosphorus, potassium content and plant nutrient parameters viz., leaf nitrogen, phosphorus and potassium were recorded. The yield parameters like number of fruits per plant, fruit girth, and fruit weight, green fruit yield per plant and per plot were also recorded. The study revealed that the soil and plant nutrient contents in general increased up to 120 days and then declined. Among the several treatments, NPK @ 100 per cent recommended dose of water soluble fertilizers along with liquid biofertilizers registered the highest value for the soil, plant nutrient content and yield parameters.Keywords

The high calorific value of the oil and the protein content of the peanuts make them a cheap and nourishing item of the diet. The whole peanut often proves rather indigestible because the nut meats are not broken into small enough particles in the process of chewing. For this reason, the product consisting of finely ground nuts known as peanut butter has become a foodstuff of increasing importance.- Nutritive Value of Differently Processed Sesame Meals and the Effect of Supplementation of the Meals with Lysine and Methionine

Hydro forming is a method of deforming sheet metal and tubular materials with the help of pressurized fluid medium using closed dies. In tube hydro forming process an internal fluid medium (inside the tube) serves as the forming medium and the tube is bulged into the desired shape through simultaneous application of axial feed and internal pressure. This paper aims to study the formability characteristic for aluminum tubular materials (A9 6063) for expansion zone geometry by considering various parameters such as axial feed, fluid medium, and semi cone angle of 20°. The formability of tube material was evaluated by varying the process parameters. In the experimental work, the tubular specimen was placed between the two halves of a split die and filled with oil as the forming medium. This tooling was mounted on a hydraulic press. The punch was advanced into the tube to increase the fluid pressure and to provide axial feed of the tube. The optimal expansion zone geometry was identified by various experimental trials, to get flaw free component.

The objective of this study is to select the optimal combination of machining parameters in Wire Electrical Discharge Machining (WEDM) process such that machining performance gets increased. Here the machining performances i.e. responses are measured in terms of Metal Removal rate (MRR), Surface Finish (SF) and Kerf (Cutting width). The most critical factors that affect performance measures are identified as Input peak voltage, Pulse-ON time, Pulse-OFF time, Dielectric fluid pressure, Wire feed, Wire speed and Servovoltage. Eighteen experimental trails based on L18 (21 × 37) orthogonal array are conducted and the corresponding responses are measured. Classical methods like factor analysis and desirability index are used for solving this multi-objective problem. Finally the results of two methods are compared and the best combination is chosen.- A World from Dust:How the Periodic Table Shaped Life

Superplastic materials undergoe large amount of plastic deformation. Since large plastic strains can be achieved at relatively low flow stresses, this process leads to considerable industrial interest in superplastic forming of aircraft parts, automobile parts etc, which require relatively high tooling and assembly cost. Therefore, the superplastic forming has become an alternative process to manufacture those components which require fewer stages with minimum wastage. The aim of this paper is to explore the superplastic deformation behavior of the AA7475 aluminum sheet during blow forming in to a circular die by numerical simulation using the Finite element package, C++, and validation with the reported results of experiment. In the theoretical modeling of superplastic forming at every stage of forming, the bulge is assumed to be a part of sphere. From this, a geometric relation is established to predict the thickness distribution, radius of curvature of the dome, height and radius of the bulge at various points of bulging during forming. In the FEM approach, a circular die is modeled and on the top of which AA7475 aluminum alloy blank is fixed rigidly around the die periphery and constant pressure is applied, which is numerically simulated using the FEM package to predict the bulge height as a function of time over the buying profile.- Overview of Big Data Analytics System for Storing and Processing Huge Data

Big data uses storage of huge data with some approaches and techniques to manage and process them. During the past few years the number of persons using internet, email and other internet based applications have been growing tremendously. Big Data is mainly characterized by Volume, Velocity and, Variety. The Big Data Architecture Framework (BDAF) is proposed to address all aspects of the Big Data Ecosystem and includes the following components: Big Data Infrastructure, Big Data Analytics, Data structures and models, Big Data Lifecycle Management, Big Data Security. The volume of data used is increasing exponentially. So, the need for storing, processing and protecting large volume of data has been becoming a great challenge in the modern hyper-connected world. Thousands of software professionals and others are doing their jobs with their internet connected laptops and mobile phones on the basis of work from home concept for development, implementation, testing and maintenance of various applications. These professionals and experts are sending and receiving lot of data to their clients, higher authorities and other officials on daily or weekly or other requirement basis. The traditional data management models are not efficient in Big data analytics. In this paper we try to give an overview of Big Data Analytics system for storing and processing huge data.

This paper proposes ontology-based Tantra Framework that accommodates Societal Information in an orderly, compact and unified manner to achieve Good Governance. In this work, Zachman Framework for Enterprise Architecture is used as reference and it is extended to address information operating at societal scale. The complexity of social information gets accentuated due to myriad possibilities of relationships, say compared to information pertaining to an Enterprise. In light of that, two additional columns namely relationships and relators have been added to Zachman Framework in Tantra Framework. The existing six columns of Zachman Framework namely who, what, how, when, where and why are interpreted as People, Assets/Attributes, Process, Event, Location and Objectives respectively. In addition to the six interrogatives of Zachman Framework that are ontology based, the concept of relationships and relators has been derived from The Unified Foundational Ontology. Even though Zachman considered his framework as Ontology, some researchers regarded it as taxonomy. Tantra Framework has addressed that perceived gap by extending the Zachman Framework by adding two additional columns. Application ScenariosThe utility of Tantra Framework is analyzed by applying it to a set of Application Scenarios pertaining to People and Locations information, Revenue Capture, Social Benefit Coverage Analysis, Financial Inclusion and Metrics analysis. Tanta Framework interoperates with Balanced Score Card approach to set objectives, Theory of Change to lay out a process of change and Bartels’ theory of Market Separations to assess the access barriers within Society. This research study is focused on Indian context. Tantra Framework relies on eliciting the inherent order in social information to make it complete, correct and current. For example, in Chemistry, discovery of periodic table by Mendeleev led to a unifying scheme which not only captured the present but allowed for place-holders for future discoveries. A similar focus on eliciting inherent order in social information, can potentially reveal latent ‘facts’, ‘truths’ and ‘relationships.Keywords

In India, post economic liberalisation period starting from early 1990s opened up new vistas for rapid development of Indian stock markets accompanied by high volatility in stock exchanges. The volume of trade increased rapidly with more number of retail investors beginning to invest in equity shares of listed companies in specific industry sectors. This brought to the fore the importance of analysis of business and financial risks associated with such investment decisions. Every rational investor will do well to analyse the risk and return before investing in any stock or security. The investment process must be considered in terms of both risk and return. The present study deals with the estimation of business risk and financial risk of the selected companies in selected industries, based on empirical analysis. For the study, six industries such as Automobile, Cement, Paint, Paper, Pharmaceuticals and Personal Care(FMCG) have been selected from the Indian industries from April 1996 to March 2020. The findings of the study revealed the extent of the relationship between business and financial risk and return in specific sectors of industry in India.Keywords
