Industrial wastes, such as, fly ash, blast furnace slag and sludge, black liquor lignin, red mud, and waste slurry, etc. are currently being investigated as potential adsorbents for the removal of the heavy metals from wastewater. It was found that modified industrial wastes showed higher adsorption capacity. The application of low-cost adsorbents obtained from the industrial wastes as a replacement for costly conventional methods of removing heavy metal ions from wastewater has been reviewed. The adsorption mechanism, influencing factors, favorable conditions, and competitive ions etc. on the adsorption of heavy metals have also been discussed in this article. From the review, it is evident that certain industrial waste materials have demonstrated high removal capacities for the heavy metals laden with wastewater. However, it is to be mentioned that adsorption capacities of the adsorbents vary depending on the characteristics of the adsorbents, the extent of chemical modification and the concentration of adsorbates. There are also few issues and drawbacks on the utilization of industrial wastes as low-cost adsorbents that have been addressed. In order to find out the practical utilization of industrial waste as low-cost adsorbents on the commercial scale, more research should be conducted in this direction. © 2011 Elsevier B.V.

The aim of this article is to introduce and study the notion of lacunary ideal convergence in intuitionistic fuzzy normed linear spaces as a variant of the notion of ideal convergence. Also, a new concept, called lacunary convergence, is introduced. Using these two notions, lacunary I-limit points and lacunary I-cluster points have been defined and the relation between them has been established. Characterization for lacunary ideal convergence preserving linear operators has been given. Furthermore, the notions of lacunary Cauchy and lacunary I-Cauchy sequences are introduced and studied. © 2011 Elsevier Ltd. All rights reserved.

This paper proposes a new formulation of the combined Optimal Active and Reactive Dispatch (OARD) problem with Minimum Control Movements (MCM) for the voltage control devices. The main objective of the proposed model is to minimize the total power system operation cost which include fuel cost of generators and switching cost of equipments like tap transformers and shunt capacitors. Practical constraints such as maximum allowable number of switching operation in a day for tap changing transformers and switchable capacitors are taken into consideration. A penalty based approach has been formulated to tackle with the switching costs of adjustable equipments. The problem has been formulated as a nonlinear dynamic optimization problem with the presence of both continuous and discrete control variables and solved using Artificial Bee's Colony (ABC) algorithm. The approach has been tested on IEEE 30 bus system and the simulation is carried out in MATLAB. In order to verify the effectiveness of the results obtained, both active and reactive power dispatch problems have been solved separately and compared with the proposed approach. Results demonstrate the effectiveness of the proposed approach. © 2012 Elsevier Ltd. All rights reserved.

The present investigation describes the potential of acid activated papaya leaf for the adsorption of methyl orange (MO) dye from aqueous solution. The FT-IR analysis indicated the presence of a wide variety of functional groups on the surface of the activated papaya leaf. Scanning electron microscopy and Electron dispersion X-ray techniques indicated the morphological behavior of adsorption onto the adsorbent, and weight percentage of chemical compositions available on the surface of adsorbent. The parameters, such as pH, contact time, and agitation rate giving the highest adsorption efficiency were obtained at 2, 120 min, and 150 rpm, respectively. The Langmuir model was found to represent the isotherm data better than other isotherms studied. Batch adsorption studies, based on the assumption of a pseudo first-order, Elovich Equation, and the pseudo second-order showed that the kinetic data followed closely a pseudo second-order mechanism. The adsorption capacity of activated papaya leaf for the removal of MO dye was found to be 333.34 mg/g. These showed that papaya leaf could be considered as a good and economical substitute of commercial activated carbon. © 2012 Copyright Taylor and Francis Group, LLC.

Biodiesel is widely accepted as comparable fuel to diesel in compression ignition engines. It offers many advantages including: higher cetane number; reduced emissions of particulates, NOx, SOx, CO, and hydrocarbons; reduced toxicity; improved safety; and lower lifecycle CO 2 emissions. A characteristic of biodiesel limiting its application is its relatively poor low-temperature flow properties. Improvement of its low temperature flow characteristic still remains one of the major challenges when using biodiesel as an alternative fuel for diesel engines. The biodiesel fuels derived from fats or oils with significant amounts of saturated fatty compounds display higher cloud points and pour points thus limiting their applications. The cold flow properties of different biodiesel were evaluated with various additives towards the objectives of improving the viscosity, pour point and cloud point. Methanol ethanol, kerosene, Mg additives, etc. have been tried many researchers to improve the cold flow behavior of biodiesels. Varying results of improvement in cold flow properties have been obtained by using different additives. Similarly different additives have been used by different researchers to improve the performance of a compression ignition engine and its emissions. This review has been taken up to identify the various additives used to improve the cold flow properties of biodiesels and improve the performance of a diesel engine and its emissions while using additive blended biodiesels. The review concludes that the additives usage in biodiesel is inseparable both for improving the cold flow properties and for the better engine performance and emission control and further research is needed to develop biodiesel specific additives. © 2011 Elsevier Ltd.
