An attempt was made to establish a mechanistic linkage between chemical speciation of copper and nickel, and their bioavailability in mangrove ecosystem. Kinetic speciation study was performed to determine the concentrations of labile metal-complexes and their dissociation rate constants in mangrove sediments. Concentrations of copper and nickel in the(More)
This review is the first attempt to comprehend the changes in metal contamination levels in surface estuarine sediments with changing time around India. Contamination factor, geoaccumulation index, pollution load index, effects range low and effects range median analysis were used to evaluate the quality of the estuarine sediments (by using the available(More)
Sequential extraction study was performed to determine the concentrations of non-residual metal-complexes in the mangrove sediments from the Divar Island, (west coast of India). Accumulation of metal in the mangrove roots (from the same location) was determined and used as an indicator of bioavailability of metal. An attempt was made to establish a(More)
Surface emission from Dhapa, the only garbage disposal ground in Kolkata, is a matter of concern to the local environment and also fuels the issues of occupational and environmental health. Surface emission of the Dhapa landfill site was studied using a flux chamber measurement for nonmethane volatile organic compounds (NMVOCs). Eighteen noncarbonyl(More)
Cooperative communication or distributed multi-input multi-output (DMIMO) system is a key enabler of coverage extension and enhancement of link reliability. The fundamental difficulty in deployment of DMIMO is synchronization, tracking independent oscillators and propagation delays. On the other hand, as orthogonal frequency division multiplexing (OFDM) is(More)
Cooperation in a vehicular network allows to opportunistically form a virtual antenna array (VAA) to accelerate information exchange resulting in safer transportation. Moving to such cooperative communication requires synchronization in order to realize the concept of the distributed coherence. In this paper, we propose a joint parameter estimation of(More)
