TiO2 dye-sensitized solar cells (DSSCs) have been fabricated using TiO2 photoelectrodes sensitized using the extracts of Delonix regia (May flower, locally called Vakai) and Eugenia Jambolana (Indian blackberry, locally called Naval) as natural sensitizers and their characteristics have been studied. Among them Eugenia Jambolana gave the best photosensitization effect and presents the prospect to be used as an environment-friendly, low-cost alternative system. The extracts having anthocyanin pigment (cyanidin 3-O-glucoside), which have carboxylic groups in the molecule can attach effectively to the surface of TiO2 film. The solar cell constructed using the Eugenia Jambolana sensitized TiO2 photo-electrode exhibited a short-circuit photocurrent of 1.49mA and a power conversion efficiency of 0.5%. © 2011 Elsevier Ltd.

Solar energy can be harvested either by deriving directly from sunlight or by indirect methods. A variety of technologies have been developed to harness solar energy. Among them, utilisation of solar energy by solar cell is an important and effective method and has a high potential in the commercial market. Based on the techniques and materials used to fabricate solar cell, the solar cells are classified into three generations. First generation solar cells are the larger, silicon based photovoltaic cells. The disadvantages of these solar cells are limited availability of silicon, requires expensive manufacturing technologies and higher energy photons are wasted as heat. The second generation solar cells are called thin film solar cells, which are significantly cheaper than previous generation cells but have lower efficiencies. The third generation solar cells are still in the research phase, but the results are promising and encouraging. Generally, third generation cells include nanocrystalline solar cells and dye sensitised solar cells, they do not have the p-n junction as in traditional solar cells. Third generation solar cells provide a technically and economically credible alternative concept to present day p-n junction solar cells. In the present study, the technology of the dye sensitised solar cell is introduced with a short description about the operating principle of the cell. After this, a more detailed study is carried out about the dye sensitised solar cell, taking into account the key steps involved in photovoltaic energy conversion and also the other important fundamental operational aspects of the solar cell physics and chemistry. © 2013 W.

The treatment of bleaching-effluent from pulp and paper industry was investigated in a batch electrocoagulation (EC) reactor using aluminium as sacrificial electrodes. The response surface methodology (RSM) was employed to evaluate the individual and interactive effects of four independent parameters viz., current density (j: 5-25 mA/cm 2), initial pH (pH o: 5-9), electrolyte (NaCl) concentration (c: 0-2 g/L) and electrolysis time (t: 10-30 min) on Colour, COD and BOD removal efficiency. The results were analyzed using Pareto analysis of variance (ANOVA). Based on RSM analysis, a second-order polynomial regression model was developed and found to be good fit with experimental results.

The experiments were carried out in an electrocoagulation reactor with aluminum as sacrificial electrodes. The influence of electrolysis time, current density, pH, NaCl concentration, rotational speed of the stirrer and electrode distance on reduction of color, COD and BOD were studied in detail. From the experimental results, 15mA/cm2 current density, pH of 7, 1g/l NaCl, 100rpm, 28°C temperature and 3cm electrode distance were found to be optimum for maximum reduction of color, COD and BOD. The reduction of color, COD and BOD under the optimum condition were found to be 94%, 90% and 87% respectively. The electrode energy consumption was calculated and found to be varied from 10.1 to 12.9kWh/m3 depending on the operating conditions. Under optimal operating condition such as 15mA/cm2 current density, pH of 7, 1g/l NaCl, 100rpm, 28°C temperature and 3cm electrode distance, the operating cost was found to be 1.56US $/m3. The experimental results proved that the electrocoagulation is a suitable method for treating bleaching plant effluents for reuse. © 2010 Elsevier B.V.

Liquefied petroleum gas (LPG) is one of the most convenient sources of fuel for cook stoves. The main reasons why LPG is widely adopted for house hold are: it is convenient to operate, easy to control, and clean to use because of the blue flame emitted during cooking. However, because of the continued increase in the price of oil in the world market, the price of LPG fuel had gone up tremendously and is continuously increasing at a fast rate. With this problem on the price of LPG fuel, research centres and institutions are challenged to develop a technology for cooking that will utilize alternative sources other than LPG. The potential of biomass as alternative fuel source to replace LPG is a promising option. Henceforth this project work focus on fabricating an environmental friendly, low cost, fixed bed (down draft) biomass gasifier that completely utilize producer gas and converts it into efficient energy resource. © 2006-2015 Asian Research Publishing Network (ARPN).

Eco-efficient products are the new generation of bio-based products prepared with sustainable materials, which agree with ecological and economic requirements including environmentally acceptable disposal of post-user waste. Increasing environmental concerns associated with handling of plastic waste has emphasized the importance of developing biodegradable edible films from starch. The objective of this study is to develop models and study the individual and interactive effects of the process variables on the mechanical properties of tapioca starch-based edible films using Box-Behnken design. Box-Behnken design with four factors at three levels was employed to evaluate the individual and interactive effects of process parameters (tapioca starch 1-3g; glycerol 0.5-1.0ml; agar 0.5-1.0g; and span 80: 0.1-0.5ml) on the tensile strength, elongation, Young's modulus, puncture force, and puncture deformation respectively. The results were analyzed using Pareto analysis of variance (ANOVA). For each response, second order polynomial regression models were developed and it showed good fit of the experimental data with high coefficient of determination (R 2) and a close agreement between experimental and predicted values was found. The response surface and contour plots were constructed for representing the relationship between the process parameters and the responses. © 2012 Elsevier B.V.

Distributed Denial-of-Service (DDoS) attacks are becoming a major problem to both the internet and internet services. Congestion is caused by malicious hosts that are not obeying traditional end-to-end congestion control; the problem must be handled by routers. Functionality is added to each router to detect and preferentially drop packets that probably belong to an attack. Client puzzles have been advocated as a promising countermeasure to Denial-of-Service (DoS) attacks in the recent years. In order to identify the attackers, the victim server issues a puzzle to the client. When the client is able to solve the puzzle, it is assumed to be authentic and the traffic from it is allowed into the server. In order to attain the advantages of both pushback and puzzle solving techniques, a hybrid scheme called router-based pushback technique, which involves both techniques to solve the problem of DDoS attacks, is proposed. In this proposal, the puzzle-solving mechanism is pushed back to the core routers rather than to the victim. The router-based client puzzle mechanism checks the host system whether it is legitimate or not by providing a puzzle to be solved by the client. Copyright © 2010 Inderscience Enterprises Ltd.
