The unsteady flow over a continuously shrinking surface with wall mass suction in a water based nanofluid containing different type of nanoparticles: Cu, Al 2O 3 and TiO 2 is numerically studied. Similarity equations are obtained through the application of similarity transformation techniques. The shooting method is used to solve the similarity equations for different values of the wall mass suction, the unsteadiness and the nanoparticle volume fraction parameters. The results of skin friction coefficient f″(0) and heat transfer rate -θ′(0) are presented in tables and graphs. It is found that dual solution exists for a certain range of wall mass suction s, volume fraction and unsteadiness parameters A. The results of velocity and temperature profiles are also presented. It is seen that two values of boundary layer thickness η ∞ are obtained, which gives two different velocity and temperature profiles that satisfy the boundary conditions. It is also found that the nanoparticle volume fraction parameter and types of nanofluid play an important role to significantly determine the flow behaviour. © 2011 Elsevier Ltd. All rights reserved.

Sustainable economic growth needs to be the primary objective of every government, including developing Asian countries, to improve the social welfare of the people. Therefore, to achieve the desirable level of sustainable economic growth, environmental degradation must be controlled without lowering real growth and the well-being of the society. This study empirically investigates the impact of environmental degradation by CO2 emissions on the economic growth of 11 Asian countries between 1990 and 2011. Based on the nature of the data, traditional panel estimation techniques encompassing fixed effects and random effects are employed, in which the results of Hausman's test and other tests show that the use of fixed effects is preferable over the random-effect estimator. Empirical results exhibit that environmental degradation has a significantly negative impact on economic growth. Empirical findings also suggest that environmental degradation should be regulated. Therefore, environmentally enlightened management policies for the decrease of CO2 emissions and fuel consumption by transportation and industries need to be pursued by Asian countries. The adoption of safe carbon emission cut-back policies is a promising path to sustainable economic growth. © 2016 Elsevier Ltd

Aim This study addressed the question of whether social support (supervisor support and co-worker support) could contribute to the variance in work engagement. Background Nurses, as customer-contact employees, play an important role in representing the organization's competence. Their attitudes and behaviour toward patients has a significant influence on patients' satisfaction and perception of quality of service. Methods The sample comprised 402 staff nurses working in three general hospitals in Peninsular Malaysia. Variables included demographic information, Utrecht Work Engagement Scale and Social Support Scale. Data analysis included descriptive statistics, correlations and regression analysis. Results Findings indicated that supervisor support was positively related to work engagement. Co-worker support was found to have no effect on work engagement. Conclusions Supervisory support is an important predictor of work engagement for nurses. Implications for nursing management Nursing management should provide more training to nurse supervisors and develop nurse mentoring programmes to encourage more support to nurses. © 2012 John Wiley & Sons Ltd.

The trend towards real-time optical applications predicates the need for real-time interferometry. For real-time interferometric applications, rapid processing of computer generated holograms is crucial as the intractability of rapid phase changes may compromise the input to the system. This paper introduces the design of a set of binary encoded computer generated holograms (CGHs) for real-time five-frame temporal phase shifting interferometry using a binary amplitude spatial light modulator. It is suitable for portable devices with constraints in computational power. The new set of binary encoded CGHs is used for measuring the phase of the generated electric field for a real-time selective launch in multimode fiber. The processing time for the new set of CGHs was reduced by up to 65% relative to the original encoding scheme. The results obtained from the new interferometric technique are in good agreement with the results obtained by phase shifting by means of a piezodriven flat mirror. © 2011 Optical Society of America.

Today's world is mostly dependent on fossil fuel for power generation. The dependency in fossil fuel is leading the world into a complex crisis comprising the insecurity of supplies, environment impact and also the fluctuation of fuel price. With a view to tackle this crisis, scientists are shifting their interest on new energy sources like biomass resources, solar, tidal and geothermal energies. Among these, biomass resources have been around for domestic use for a long time, but have not yet been utilised for industrial-scale power generation. Whereas other renewable sources have a long way to go in the path to technological advancement to be utilised in a mass scale and compete with fossil fuel as a cost-effective alternative. The most potential biomass resource is lignocellulosic biomass, which includes paddy residue. Paddy residues are widely abundant agricultural wastes which have a high potential for utilisation in energy industries. The major challenges for the proper utilisation of paddy residues in power generation are management, lack of economic study, and lack of collection network. Lastly, the economic, environment and energy policies play an important role for developing paddy residues as a fuel for energy industries. © 2016 Elsevier Ltd. All rights reserved.

Solid waste is one of the major environmental problems in Libya. It plays a significant role in the ability of nature to sustain life within its capacity. Recycling of solid wastes is considered as one the solutions to recover the waste generated. This study aimed to examine the restrictions that hinder residents from practicing recycling. A structured questionnaire was designed to serve as the instrument for the collection of data which was administered on 700 randomly selected in the city of Al-Marj. Out of the 700 questionnaires sent out, only 482 were retrieved representing a response rate of 69%. Based on the findings, it was found that the majority of the residents in the city believed that recycling solid waste is a very important activity; however, their attitude toward this activity was found to be negative. The residents did not recycle nor were they involved in such activities. Most residents do not know how to recycle solid waste; some of them did not even know the items that can be recycled. © 2016, ASERS Publishing House. All rights reserved.

Reverse logistics and green product design are green supply chain management practices that are being implemented to demonstrate firm's commitment to environmental sustainability. The generation of waste from electrical and electronic equipments prompts the viability of product recovery to salvage invested material and energy. Selection of various reverse logistics product disposition options relies on products' residual value and the accessibility of reusable content for re-entry in forward supply chain. This study explores the effect of green product design and resource commitment on reverse logistics product disposition by employing empirical analysis on 89 returned mail survey received from ISO14001 certified electrical and electronic manufacturing firms in Malaysia. The results indicated that design for disassembly is necessary to harvest valuable inventories from every product disposition options except of disposal whereas design for environment and commitment of resources have slight influence on repair and disposal activities. As the evidences show that green product design and reverse logistics product disposition are interrelated, firms ought to undertake environmentally proactive approaches to generate benefits from resources that are undeservingly discarded as landfill waste. © 2013 Elsevier B.V.

This study of environmental management in the food service industry in general and the restaurant sector in particular highlights food services' impacts on the environment, and drivers and barriers to change. The study is based on research in Penang, Malaysia, which included a personally assisted survey of 26 restaurant managers operating casual upscale businesses. The survey findings show that implementation of environmentally friendly practices is weak in the restaurant sector. While top managers claim to be informed and concerned about environmental issues, they are reluctant to invest in environmental management systems, to change practices, to advertise environmentally friendly products or invest in the implementation of environmentally friendly practices. They note barriers to change, including weakly enforced environmental laws and regulations, scarce and intermittent green supply chain, non-existent trade pressure and poor customer and community demand for restaurant business to implement green practices. A model of barriers and drivers leading to the implementation of environmentally friendly practices is presented in this study. Government intervention, including public education, capacity building and support in the trade and agricultural change to grow more organic crops, is suggested. The study depicts the responsiveness of restaurateurs towards the implementation of environmentally friendly practices in the context of a developing country. © 2012 Copyright Taylor and Francis Group, LLC.

Replication is an important activity in determining the availability of resources in data grid. Nevertheless, due to high computational and storage cost, having replicas for all existing resources may not be an efficient practice. Existing approach in data replication have been focusing on utilizing information on the resource itself or network capability in order to determine replication of resources. In this paper, we present the integration of three types of relationships for the mentioned purpose. The undertaken approach combines the viewpoint of user, file system and the grid itself in identifying important resource that requires replication. Experimental work has been done via OptorSim and evaluation is made based on the job execution time. Results suggested that the proposed strategy produces a better outcome compared to existing approaches. © 2014 Springer-Verlag Berlin Heidelberg.

This study investigates the relationship between electricity consumption and real gross domestic product in Botswana (the world's largest producer of diamonds). The study includes capital formation in a trivariate system for the period covering 1980-2008. Zivot and Andrews (1992) unit roots test; bound test for cointegration, and Granger causality test are employed. Unidirectional causality is found from electricity consumption to real gross domestic product is in line with study of Altinay and Karagol (2005) among others. The long run estimate reinforce the Granger causality tests by indicating that electricity consumption is positively associated with real gross domestic product in the long run. Further findings suggest unidirectional causality from capital formation to real gross domestic product. The implication is that Botswana-being a highly energy dependent country-will have the performance of its capital formation on the economy partly determined by adequate electricity.
