One of the important functions of Futures market is Price discovery. Futures markets provide a mechanism through which information about current and futures Spot prices can be assimilated and disseminated to all participants in the economy. The ability of future markets to provide information about price is a central theme for the existence of these markets. The paper has examined whether the futures market is performing its primary role of price discovery. The main objective of the study is to examine whether any long run equilibrium relationship exists between spot market and future market and to identify the lead-lag relationship between these markets. The daily NSE closing prices of Nifty Spot Index and Nifty Index Futures of near month contracts from January 2013 to December 2013 have been taken for the study purpose. After obtaining the stationarity of the series by conducting Augmented Dickey Fuller Test, Granger’s Co integration Test and Johansen Co integration Test have been conducted on the Nifty Spot and Nifty futures. The empirical results indicate that there exists long run equilibrium between these two markets. Further Granger’s Causality Test results indicate that there exists lead –lag relationship between these Spot market and Future market. It also shows that there is much feedback from Futures market to Spot market in impounding information in its prices. Finally from overall empirical results we propose that Futures markets are more efficient in discovering the Future spot price. © Research India Publications. Source

The Poverty may be a complicated and stereotypical drawback at both national and international levels. There are no bilaterally symmetrical measures known which would be suitable for worldwide application. However, every country takes specific initiatives to tackle poverty and international efforts go along with nation’s efforts for up-rooting this crisis. Creating a compassionate International environment is a serious answer to the current draw-backs. This paper intends to review the poverty level as a threating issue for sustainable development in top four international developing countries. Wiping-out poverty is a supreme international challenge which the world faces nowadays and there is an increasing demand for sustainable development, especially for developing countries. This paper strives to find out in what way impoverishment can have an adverse effect on the countries sustainable development, particularly in developing countries. This paper also aims to explain the cause of poverty, to chalk out a mechanism to wipe it out and to create opportunities for sustainable development. © 2016, Politechnika Lubelska.

Chemically activated "Waste" Jute Fiber carbon has been effectively used for the removal of five organophosphorous pesticides (malathion, monocrotophos, methylparathion, phosphamidon and dimethoate) from aqueous solutions. The prepared activated jute fiber carbon was characterized by using Elemental analyzer and proximate analysis methods. The adsorption equilibrium was examined at 28 °C. Three different kinetic models, the pseudo first order, pseudo second order and Elovich kinetic models were selected to analyses the adsorption process. To compare the fitness of pseudo first order and pseudo second order, sum of the squares of the errors and correlation coefficient, r 2 values were calculated. The Elovich model was used to confirm the chemisorptions. Source

The selection of optimum machining conditions, during wire electric discharge machining process, is of great concern in manufacturing industries these days. The increasing quality demands, at higher productivity levels, require the wire electric discharge machining process to be executed more efficiently. As the process involves more than one response characteristic, it is needed to implement the multi-response optimization methodologies for optimize the process parameter and ensuring with low cost of manufacturing. This article addresses an approach based on the Taquchi Data Envelopment Analysis-based Ranking methodology (DEAR) for optimizing wedm operations with multiple responses by using reusable molybdenum wire electrode in Suzhou Baoma BMW 2008 Wirecut EDM. The relation between Input parameters including wire speed, pulse on time, pulse off time, peak current and table feed are optimized with consideration of the multi- response characteristics viz., metal removal rate (MRR), surface roughness (SR) and kerf width (KW) on WEDM in industrial chain link material as EN 9. is studied via experimental result analysis and mathematical modeling. Outputs extracted from Taquchi Data Envelopment Analysis Ranking (DEAR) used for optimization of output parameters resulted with optimal solutions. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

Hydrochemistry of groundwater in Erode district, TamilNadu, India was studied to assess the quality of groundwater for determining its suitability for drinking and agricultural purposes. Various physico-chemical parameters, such as pH, total dissolved solids (TDS), hardness, electrical conductivity (EC), sodium, potassium, calcium, magnesium, bicarbonate, carbonate, nitrate, sulphate, chloride and fluoride were determined using standard procedures. The results were compared with the standard values prescribed by the Word Health Organization (WHO 1993). From the drinking water standards, it is found that most of the locations in the study area are contaminated by higher concentration of EC, TDS, K+ and NO3 - due to the rock water interaction and anthropogenic activities such as intense agricultural practices (application of fertilizers, irrigation practice), urban and industrial waste discharge among others. Based on the analytical results, chemical indices like Sodium adsorption ratio (SAR), Sodium percentage (Na %), Salinity hazard and Residual sodium carbonate (RSC) were calculated. The hydro chemical types Ca-HCO3, Na-Cl and mixed Ca-Mg-Cl are the predominant forms in the groundwater followed by water type Ca-Na-HCO3.According to Gibb's diagram maximum samples fall in the rock dominance field. Principal Component Analysis was used to predict the dominating water quality constituents and it revealed that three principal components are accounted for the total chemical variability in the groundwater quality. Assessments of water samples from various methods proved that majority of the water samples are good either for drinking or for agriculture. © Research India Publications. Source
