Heavy metals are natural constituents of the earth's crust, but indiscriminate human activities have drastically altered their geochemical cycles and biochemical balance. This results in accumulation of metals in plant parts having secondary metabolites, which is responsible for a particular pharmacological activity. Prolonged exposure to heavy metals such(More)
In this paper, a novel digital image watermarking algorithm based on a fast neural network known as Extreme Learning Machine (ELM) for two grayscale images is proposed. The ELM algorithm is very fast and completes its training in milliseconds unlike its other counterparts such as BPN. The proposed watermarking algorithm trains the ELM by using low frequency(More)
ZnO nanostructures of diverse shape were grown via a solution process with different precursors and conditions. Morphological investigation of the nanostructures was carried out using field emission scanning electron microscopy and transmission microscopy observations and revealed that the nanostructures exhibit a wurtzite phase with an ideal lattice fringe(More)
Two new and large molecular rectangles 4 and 5 were synthesized from two different arene-ruthenium [Ru(2)(μ-η(4)-C(2)O(4))(MeOH)(2)(η(6)-p-Pr(i)C(6)H(4)Me)(2)][O(3)SCF(3)](2) (2), and [Ru(2) (p-cymene)(2) (donq) (OH(2))(2)] [O(3)SCF(3)](2) (donq = 5,8-dioxydo-1,4-naphthaquinonato) (3) acceptors and a new unsymmetrical N-(4-(pyridin-4-ylethynyl)phenyl)(More)
The ligands 2-(N-(X-pyridyl)carbamoyl)pyridine (X=2, 3 or 4 for HL1-HL3, respectively) and 2,6-bis(N-(Y-pyridyl)carbamoyl)pyridine (Y=2, 3 or 4 for H2L4-H2L6, respectively) in their mono- and di-deprotonated forms have been used to synthesize kinetically stable cobalt(III) compounds [Co(L1-3)3] (1-3) and Na[Co(L4-6)2] (4-6), respectively. The Co(III) ion is(More)
A pair of L-shaped slot loaded rectangular patch antenna is analysed by using circuit theory concept which exhibits dual resonance behaviour. Two resonance frequencies are at 2.45 GHz and 5.125 GHz (experimental 2.44GHz and 5.12GHz, simulated 2.48 GHz and 5.2 GHz). The −10 dB bandwidth of lower and upper resonance frequency is 4.13 % (experimental(More)
