The relaxation of an electron-depleted electronegative dusty plasma with two-negative ions is investigated. When the ratio of canonical vorticities to corresponding flows of all the plasma species is the same and all inertial and non-inertial forces are present, the relaxed state appears as a double Beltrami magnetic field which is the superposition of two force-free relaxed states. The numerical results show that highly diamagnetic relaxed magnetic fields can be obtained by controlling the flow and vorticities through a single Beltrami parameter. The study is useful to investigate the creation of diamagnetic plasma configurations which are considered to be very important in the context of nuclear fusion.

Environmental Impact Assessment Review

Evaluating the effectiveness of public participation in EIA related decisions is of crucial importance for developing a better understanding of overall EIA effectiveness. This paper aims to contribute to the professional debate by establishing a country specific evaluation framework for Pakistan, which, it is suggested, could also potentially be used in other developing countries. The framework is used to evaluate performance of public participation in EIA in terms of 40 attributes for four selected projects from the province of Punjab. The evaluation is based on interviews with stakeholders, review of EIA reports as well as public hearing proceedings and environmental approval conditions. The evaluation of the selected projects revealed an overall weak influence of public participation on substantive quality of EIA and on the final decision. Overall, EIA public participation has succeeded in providing a more egalitarian environment. Furthermore, it appears fair to say that sufficient time for submitting written comments on EIA reports as well as for raising concerns during public hearings had been given. Also, public consultation was significantly contributing to educating participants. Despite some impediments, it is argued that public participation in EIA is gradually gaining ground in Pakistan. Recommendations to enhance EIA public participation effectiveness in Pakistan include applying a more proactive approach which should take place before EIA is conducted and before site selection for development projects is happening. © 2010 Elsevier Inc.

LED based lighting systems provide an opportunity for data transmission in addition to their traditional use as source of illumination. Brightness control is required to achieve either desired level of illumination or to achieve energy conservation. Conventionally, simultaneous data transmission as well as brightness control is achieved using two different modulation schemes. Either pulse width modulation or pulse amplitude modulation is used for brightness control and some variants of pulse position modulation are employed for data transmission. The need for two different modulation schemes, to meet the dual objective, makes the system design complex. In this paper we propose variable-rate multi-pulse-position-modulation (VR-MPPM), for LED based visible light communication system, to achieve joint brightness control and data transmission. The proposed approach eradicates the need for either pulse width modulation or pulse amplitude modulation and still achieves the brightness control. Encoder and decoder algorithms for VR-MPPM realization are developed and are implemented on the hardware testbed. Experimental results revealing the effect of brightness level variation on symbol error rate are also provided. Existence of an underlying trade-off between achievable resolution for brightness control and the corresponding successful data transmission rate is recognized. To exploit this trade-off, an optimization problem is formulated. © 2013 IEEE. Source

Water into oxygen: Mono-iridium complexes (see picture; L=PO 3H2 or COOH) were immobilized on an indium tin oxide (ITO) surface to form a molecular electrocatalytic water oxidation assembly that mimics photosystem II in producing molecular oxygen with high turnover numbers (TONs). The catalyst shows TONs for O2 higher than 210 000 and turnover frequencies higher than 6.7 s-1 during electrochemical catalytic water splitting. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.

The development of new energy materials that can be utilized to make renewable and clean fuels from abundant and easily accessible resources is among the most challenging and demanding tasks in science today. Solar-powered catalytic water-splitting processes can be exploited as a source of electrons and protons to make clean renewable fuels, such as hydrogen, and in the sequestration of CO2 and its conversion into low-carbon energy carriers. Recently, there have been tremendous efforts to build up a stand-alone solar-to-fuel conversion device, the "artificial leaf", using light and water as raw materials. An overview of the recent progress in electrochemical and photo-electrocatalytic water splitting devices is presented, using both molecular water oxidation complexes (WOCs) and nano-structured assemblies to develop an artificial photosynthetic system. Turning a new leaf: Electrochemical and light-driven electrocatalytic water oxidation assemblies have been targeted to develop artificial photosynthetic system. Such "Artificial Leaves" are used to make H2 and O2 using water as a raw material. The design and performance of the water oxidation systems and standalone solar-to-fuel conversion devices are presented. Progress in the field and future perspectives of water splitting are also discussed. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source
