Combination of tool and work piece material has a very significant role for surface finish in turning operation. There are many different types of tool inserts with different material and tool insert geometry which are used in turning operation for good surface finish. This paper describes an optimal procedure to select best tool insert from various tool inserts for better surface finish in turning operation. Multiple Attribute Decision Making methods is been used in various areas such as society, economics, military, management, manufacturing etc., and is been receiving more and more attention over the last few years.In this research work, three work-piece materials i.e., EN 8, SS304 and EN 19 and three tool inserts i.e., 1) DVJNR 2020K 16-VBMT 16 04 08 MF, 2) WNMG 08 04 08 MF-MWLNL 2020K 08, 3) PDJNR 2020K 15-DNMG 15 06 08 MF are taken. The right choice oftool insert-work piece material is VBMT 16 04 08 MF and EN-8 for better surface finish. A tool insert selection index is provided that evaluates and ranks the tool insert for good surface finish in turning operation. © 2017 Elsevier Ltd. All rights reserved.

The focus of this paper is on behavior of compacted dune sand-clay mixture for hydraulic conductivity. In the North Western part of the country, the Great Thar Desert suffers absence of impervious natural soils, hence effort has been made to compacted mixture of dune sand and clay to form barricade to fluids. Various laboratory investigations were made and effects of the mixture were studied. The effect of addition of the clay is reflected in low hydraulic conductivity. Experimentally compaction and hydraulic conductivity characteristics of the mix were studied. It was found that hydraulic conductivity of dune sand reduces from 10-4 cm/s to 10-9 cm/s after addition of 12% clay. © 2013, EJGE.

The object of the present investigations is to study the strength characteristics of dune sand of western Rajasthan stabilized with cheap and readily available material like lime and bentonite. Dune sand which covers a big part of western Rajasthan is weak in strength and possesses problems in construction of road. The present investigation is an attempt to stabilize this soil with the aid of lime and bentonite. Standard Proctor test, unconfined compressive strength, in addition to some preliminary tests were conducted for assessing the suitability of limebentonite mix with dune sand. © 2013, EJGE.

A method to design microstrip low pass filter having defected ground structure (DGS) is proposed. The difference between standard asymmetric microstrip technique and DGS is in using the structures etched in the microwave substrate ground plane. The DGS resonant characteristics are then used in filter design. The equivalent circuit for the proposed defected ground unit structure is derived by means of three-dimensional field analysis methods. The equivalent-circuit parameters are extracted by using a simple circuit analysis method. Filters of various orders and resonator configurations are designed and simulated. A combination of the DGS and five order low pass Chebyshev microstrip filter is designed as well realized and measurement results are compared with simulations. The experimental results show excellent agreements with theoretical results and the validity of the modeling method for the proposed defected ground unit structure. Finally, enhanced cut off frequency 2.715GHz of microstrip low pass chebyshev filter using DGS is observed. Copyright © 2013 SPIE.

This paper presents two approaches for Information Retrieval (IR) from a collection of documents: Bayesian theory of probability and Dempster-Shafer theory of belief functions. Each method has been supported with essential derivations to prove their suitability for IR. The conclusions of derivations have been applied in illustrative examples. Finally, comparison of both the methods suggests the suitability of each for specific domains. © 2011 IEEE.

Treatment technologies needed to reduce the pollutant load of chemical industry effluent have been found to involve exorbitantly high costs. The present investigation aimed to treat the wastewater from chemical industry by cost effective sequential anaerobic-adsorption treatment. Wastewaters from chemical industry that are rich in biodegradable organics are tested for anaerobic treatability. The efficiency of anaerobic reactor is relatively lower 79.3%, and therefore post treatment of effluent was done by adsorption using Poly vinyl alcohol coated Datura stramonium (PVAC-DS) as an adsorbent. An overall COD removal of 93.8 % was achieved after sequential Anaerobic-Adsorption treatment, which lead to a better final effluent and a more economical treatment system.

Raw guava juice is turbid, viscous and gray in color. This study was initiated to optimize the enzymatic clarification process of guava juice using response surface methodology. Guava juice was treated with pectinase at various enzyme concentrations (0.01-0.2%), temperatures (30-50°C) and time (30-150 min) of treatment. The effect of enzyme treatments on percentage yield, clarity, turbidity, titrable acidity and viscosity of the juice were studied by employing a second order central composite design. Based on response surface and contour plots, the optimum conditions for clarifying guava juice obtained were: 0.11% enzyme concentration, incubation temperature of 41.30°C and incubation time of 115.98 min with percent yield (80.03%), clarity (1.34 Abs), turbidity (1.07 Abs), titrable acidity (0.525%), viscosity (2.4 cps) and desirability of 0.942. Statistical analysis showed that percentage yield, clarity, viscosity and turbidity were significantly (p<0.05) correlated to enzyme concentration, incubation temperature and incubation time. © 2012 Academic Journals Inc.

In the era of globalisation, requirements of customer are changing very fast. Product life cycle is shortening. Organisations are under pressure to reduce cost, delivery time, improve reliability of product by changing their process continuously. Supply chain management has become integral part of strategy for most of the organisations in meeting these challenges. Success of supply chain depends on effective strategy for improving coordination among the members to make it more responsive for market needs by optimising available resources. In this context, supply chain needs to be flexible. Based on the literature, it is observed that overall flexibility of supply chain depends upon suppliers flexibility, manufacturing flexibility and customers flexibility. Other sub-factors affecting flexibility may be product and process design, capacity planning, logistic management, suppliers capabilities and nature of customers. This study has tried to prioritise flexibility alternatives by analytical network process approach. Input for this analysis is based on four Indian case studies, which are briefly described in the paper. These organisations had been very active in improving flexibility of their supply chains. Findings of the study report that organisations should give top priority for improving manufacturing flexibility followed by customers and suppliers flexibility. © 2013 Taylor & Francis.

Wastewater containing heavy metal pollutants cause direct toxicity, both to human and other living organisms due to their presence beyond specified limits. Industrial effluents containing nickel play an important role in polluting water bodies. The removal of nickel ions from aqueous solution by polyvinyl alcohol coated carbon prepared from Datura stramonium as an adsorbent is reported in this paper. The effect of pH, initial metal ion concentration, contact time and adsorbent dose were studied. The adsorption capacity of Datura stramonium was dependent on the pH of the nickel solution, maximum nickel removal (78.9 %) was obtained at pH of 6. The adsorption experimental data fit well with the Langmuir and Freundlich adsorption isotherms. The kinetics of the adsorption process follows the pseudo second-order kinetics model. The results indicate that Datura stramonium can be employed as a low cost alternative to commercial adsorbents in the removal of nickel (II) from wastewater.
