Hard turning is gaining grounds for machining hardened steels as it has several benefits over grinding. There are several issues, which should be understood and dealt with, to achieve successful performance of the process. Researchers have worked upon several aspects related to hard turning. The present work is an effort to review some of these works and to understand the key issues related to process performance. The review shows that the type of tool material, cutting edge geometry and cutting parameters affect the process efficiencies in terms of tool forces, surface integrities integrity, and white layer. Adequate machine rigidity is a must essential to minimize the process inaccuracies. Also moreover, for finish hard turning, where the depth of cut is less than the nose radius of the tool, the forces deviate from the conventional trends as the radial force component is the maximum and axial force component becomes minimum. The present work finally lists down certain areas that can be taken up for further research in hard turning. © 2011 Elsevier Ltd All rights reserved.

Particulate matter (PM) levels show significant seasonal variability and this can influence the neutralization of rainwater acidity. Months were grouped in two periods: monsoon (July to October) and non-monsoon (November to June) for studying the seasonal variability in PM and rainwater composition. To clearly establish the cause effect relationship of acid rain neutralization, a two tier model was proposed involving source apportionment of particulates at two levels: (i) ambient air and (ii) rainwater particulate interaction. For modelling purpose, PM10 (n= 100), soil (n= 4) and rainwater (n= 83) samples were collected at Kanpur, India during 2000-2002. The collected samples were analysed for metals and water soluble ion composition to employ factor analysis for source identification. Knowledge of statistical correlation and chemistry fundamentals were combined to estimate the sources for acid rain neutralization. NH4 + was a dominating ion responsible for neutralizing the acidity of rainwater in monsoon period and Ca2+ was dominating in non-monsoon period. Components of secondary particles (SO4 2- and NO3 -) showed affinity with NH4 +, signifying the major role that ammonia can play if present in excess of stoichiometric requirements. © 2010 The Authors Journal compilation © 2010 Blackwell Munksgaard.

The author of this paper presents a novel method to use the electrocardiogram (ECG) as a biometric for human recognition. The ECG is a physiological signal that links to the life signs of an individual and does not need vitality testing. Thus, ECG biometric system has potential to prevent the fraudulent attacks. The hybrid approach consisting analytical and appearance methods is used to derive the ECG features. In order to make the method insensitive to signal variations and muscle flexure, the ECG features are linearly projected using Fisher's discriminant method. The method selects heartbeat features of lower dimension in the Fisher space that have sufficient discriminatory information between inter-subject ECG signals. The experiment shows that the proposed ECG biometric method achieves the equal error rates (EER) of 0.76% and 0.71% in recognizing people suffering from cardiac arrhythmia and people of good health, respectively. On mixed health statuses, the method achieves an EER of 1.31% confirming a very good performance and robustness of the proposal. © 2015 Elsevier B.V.

The present paper reports the measurements of space-charge-limited conduction (SCLC) in glassy Se90Sb4Ag6 alloy. For this purpose, I-V characteristics have been taken at certain fixed temperatures. The results indicate that super-ohmic behaviour is observed at high electric fields. The results fit well with the theory of SCLC for the uniform distribution of traps. From the temperature dependence of conductivity, activation energy is obtained at different electric fields, which is found to be field dependent. Pre-exponential factor is found to depend on the activation energy and obeys Meyer-Neldel rule. © Indian Academy of Sciences.

Performance characteristics of photogalvanic cells containing mixed dye-brilliant green and celestine blue as photosensitizer with reducing agent EDTA have been experimentally examined. Photopotential of 636 mV and photocurrent of 93 μA are observed for the system. Power conversion efficiency of photogalvanic cell based on brilliant green+celestine blue-EDTA is estimated as 0.31% while the maximum power output of the cell is found to be 59.1 μW. Photogalvanic cell based on this mixed dye system may be used for 65 min in dark. This study shows that the solar energy conversion capability of a mixture of dyes in aqueous medium is controlled by dye-dye interaction, its photo-degradation and its susceptibility to photo-oxidation. © 2012 Elsevier Ltd.

The purpose of this study was to evaluate the capabilities of DMLC to deliver the respiratory motion-synchronized dynamic IMRT (MS-IMRT) treatments under various dose rates. In order to create MS-IMRT plans, the DMLC leaf motions in dynamic IMRT plans of eight lung patients were synchronized with the respiratory motion of breathing period 4 sec and amplitude 2 cm (peak to peak) using an in-house developed leaf position modification program. The MS-IMRT plans were generated for the dose rates of 100 MU/min, 400 MU/min, and 600 MU/min. All the MS-IMRT plans were delivered in a medical linear accelerator, and the fluences were measured using a 2D ion chamber array, placed over a moving platform. The accuracy of MS-IMRT deliveries was evaluated with respect to static deliveries (no compensation for target motion) using gamma test. In addition, the fluences of gated delivery of 30% duty cycle and non- MS-IMRT deliveries were also measured and compared with static deliveries. The MS-IMRT was better in terms of dosimetric accuracy, compared to gated and non-MS-IMRT deliveries. The dosimetric accuracy was observed to be significantly better for 100 MU/min MS-IMRT. However, the use of high-dose rate in a MS-IMRT delivery introduced dose-rate modulation/beam hold-offs that affected the synchronization between the DMLC leaf motion and target motion. This resulted in more dose deviations in MS-IMRT deliveries at the dose rate of 600 MU/min.

Hg(II)-ion-imprinted polymer (IIP) was prepared by the formation of a binary complex of mercury (imprint ion) with 4-(2-thiazolylazo) resorcinol (TAR) and thermally copolymerizing with methacrylic acid (monomer) and ethylene glycol dimethadrylate (crosslinker), and 2, 2'-azobisisobutyronitrile as initiator in cyclohexanol as porogen. Mercury(II) was leached with 0.5 M HCl-1 M thiourea. Control polymer (CP) was also prepared without using imprint ion. The prepared IIP and CP were characterized with FT-IR, microanalysis, SEM analysis and surface area measurement. The effect of pH, adsorption kinetic and adsorption isotherm of imprinted polymer and control polymer were studied. The mechanism for adsorption of mercury was found to follow Freundlich isotherm and pseudo first order model. The adsorption capacity of Hg(II) on IIP and CP is 125 and 57.6 μmol g-1, respectively. The relative selectivity factor (αr) values of Hg(II)/Zn(II), Hg(II)/Cu(II), Hg(II)/Ni(II) and Hg(II)/Co(II) are 62.5, 65.3, 64.6 and 70.6, respectively. The detection limit corresponding to three times the standard deviation of the blank was found to be 2.875 μg L-1. The IIP has been successfully applied for the recovery of trace Hg(II) in real water samples and those spiked with standards. © 2010 Elsevier B.V. All rights reserved.

Renewable and Sustainable Energy Reviews | Year: 2010
Anhydrous ethanol is one of the biofuels produced today and it is a subset of renewable energy. It is considered to be an excellent alternative clean-burning fuel to gasoline. Anhydrous ethanol is commercially produced by either catalytic hydration of ethylene or fermentation of biomass. Any biological material that has sugar, starch or cellulose can be used as biomass for producing anhydrous ethanol. Since ethanol-water solution forms a minimum-boiling azeotrope of composition of 89.4 mol% ethanol and 10.6 mol% water at 78.2°C and standard atmospheric pressure, the dilute ethanol-water solutions produced by fermentation process can be continuously rectified to give at best solutions containing 89.4 mol% ethanol at standard atmospheric pressure. Therefore, special process for removal of the remaining water is required for manufacture of anhydrous ethanol. Various processes for producing anhydrous ethanol have been used/suggested. These include: (i) chemical dehydration process, (ii) dehydration by vacuum distillation process, (iii) azeotropic distillation process, (iv) extractive distillation processes, (v) membrane processes, (vi) adsorption processes and (vii) diffusion distillation process. These processes of manufacturing anhydrous ethanol have been improved continuously due to the increasingly strict requirements for quantity and quality of this product. The literature available on these processes is reviewed. These processes are also compared on the basis of energy requirements. © 2010 Elsevier Ltd. All rights reserved.
