The study reports the first assessment for the quantification and speciation of butyltins (BTs) in surface marine sediment samples (0-5 cm) from intertidal mudflats of Sundarban mangrove wetland along with the Hugli (Ganges) river basin, eastern coastal part of India. Concentrations of tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MBT) were monitored at 16 stations and present at all st...

Culture-dependent and culture-independent approaches were used to determine the relationship between the dehalogenase gene pool in bacteria enriched and isolated on 2,2-dichloropropionic acid (22DCPA) and the environmental metagene pool (the collective gene pool of both the culturable and uncultured microbes) from which they were isolated. The dehalogenases in the pure-cultures isolates, which ...

The mixed record on the 2015 Millennium Development Goal (MDG) targets and the focus on global public goods in post-MDG debates questions the future of traditional development co-operation (official development assistance, ODA). Meanwhile, international financial crisis and fiscal retrenchment have focussed policy makers on the international dimensions of income and asset taxation. This paper e...

“When you make a prediction, would you rather be correct or incorrect? If your answer is'correct,' then ODA [optimal data analysis] is the appropriate analytic methodology...” (p. xi). With this audacious, provocative opening statement, Paul Yarnold and Robert Soltysik set the stage for a revolutionary paradigm shift in statistical analysis. It is obvious that no one could rationally answer “no...

This research examines the strategic conditions that drive entrepreneurial innovators to pursue novel innovation, rather than innovation that is closer to existing technologies. Since radical breakthrough innovation is harder to communicate than incremental counterpart, entrepreneurial innovators may be steered away from breakthrough innovation where the cost of developing credible information ...

in this paper, we prove the existence of the solution for boundary value prob-lem(bvp) of fractional di erential equations of order q 2 (2; 3]. the kras-noselskii's xed point theorem is applied to establish the results. in addition,we give an detailed example to demonstrate the main result.

the purpose of this letter is to revisit the nonlinear reaction-di usion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. this model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of taylors series for di erent family of reactionterms. we...

in this work, we conduct a comparative study among the combine laplace transform and modi ed adomian decomposition method (lmadm) and two traditional methods for an analytic and approximate treatment of special type of nonlinear volterra integro-diff erential equations of the second kind. the nonlinear part of integro-di fferential is approximated by adomian polynomials, and the equation is red...
