Arsenic Speciation And Phytoavailability In Contaminated Soils Using A Sequential Extraction Procedure And Xanes Spectroscopy, Nabeel Niazi, Balwant Singh, Pushan Shah
Arsenic Speciation And Phytoavailability In Contaminated Soils Using A Sequential Extraction Procedure And Xanes Spectroscopy, Nabeel Niazi, Balwant Singh, Pushan Shah
Dr Nabeel Khan Niazi
In this study, a sequential extraction procedure (SEP) and X-ray absorption near edge structure (XANES) spectroscopy were used to determine the solid-phase speciation and phytoavailability of arsenic (As) of historically contaminated soils from As containing pesticides and herbicides and soils spiked with As in the laboratory. Brassica juncea was grown in the contaminated soils to measure plant available As in a glasshouse experiment. Arsenic associated with amorphous Fe oxides was found to be the dominant phase using both SEP and XANES spectroscopy. Arsenic predominantly existed in arsenate (As V) form in the soils; in a few samples As was also …

Phytoremediation Potential Of Pityrogramma Calomelanos Var. Austroamericana And Pterris Vittata L. Grown At A Highly Variable Arsenic Contaminated Site, Nabeel Niazi, Balwant Singh, Lukas Van Zwieten, Anthony Kachenko
Dr Nabeel Khan Niazi
In this study, the phytoextraction potential of Pityrogramma calomelanos var. austroamericana (gold dust fern) was compared with the well-known arsenic (As) hyperaccumulator, Pteris vittata L. (Chinese brake fern) at a disused cattle dip site in northern New South Wales, Australia. Geostatistical analysis showed that the concentrations of total (at 0–20 cm depth) and phosphate-extractable (at 0–20, 20–40 and 40–60 cm depths) As were spatially variable at the site and this extreme variability (< 1 m) was also evident in the spatial maps of As. Gold dust fern produced greater frond dry biomass (mean=130 g/plant; n=40) than Chinese brake fern (mean=81 …

Dr Nabeel Khan Niazi
This field study investigated the phytoremediation potential of two arsenic (As) hyperaccumulating fern species, Pityrogramma calomelanos var. austroamericana and Pteris vittata over 27-month duration at a disused As-contaminated cattle-dip site located at Wollongbar, NSW, Australia. Ferns planted in January 2009 were harvested following 10, 22 and 27 months of growth. A detailed soil sampling was undertaken in June 2009 (initial, n = 42 per plot) and limited sampling in April 2011 (after 27 months, n = 15 per plot) to measure total and phosphate-extractable As concentrations in soil at 0 − 20-, 20 − 40- and 40 − 60-cm depths. …

Dr Nabeel Khan Niazi
This study examined the phytoextraction potential of two arsenic (As) hyperaccumulators, Pteris vittata L. and Pityrogramma calomelanos var. austroamericana at a historical As-contaminated cattle dip site in northern New South Wales (NSW), Australia. Total As concentration in the surface soil (0–20 cm) showed a better spatial structure than phosphate-extractable As in the surface and sub-surface soil at this site. P. calomelanos var. austroamericana produced greater frond dry biomass (mean = 130 g plant−1) than P. vittata (mean = 81 g plant−1) after 10 months of growth. Arsenic concentration and uptake in fronds were also significantly higher in P. calomelanos var. …

Exponential Stability In Functional Dynamic Equations On Time Scales, Elvan Akin, Youssef Raffoul, Christopher Tisdell
Youssef N. Raffoul
We are interested in the exponential stability of the zero solution of a functional dynamic equation on a time scale, a nonempty closed subset of real numbers. The approach is based on suitable Lyapunov functionals and certain inequalities. We apply our results to obtain exponential stability in Volterra integrodynamic equations on time scales.

Mapping Algorithms And Software Environment For Data Parallel, Nikos Chrisochoides, Elias Houstis, John Rice
John R Rice
We consider computations associated with data parallel iterative solvers used for the numerical solution of Partial Differential Equations (PDEs). The mapping of such computations into load balanced tasks requiring minimum synchronization and communication is a difficult combinatorial optimization problem. Its optimal solution is essential for the efficient parallel processing of PDE computations. Determining data mappings that optimize a number of criteria, like workload balance, synchronization and local communication, often involves the solution of an NP-Complete problem. Although data mapping algorithms have been known for a few years there is lack of qualitative and quantitative comparisons based on the actual performance …
