The work investigates on the potential of ten mangrove species for absorption, accumulation and partitioning of trace metal(loid)s in individual plant tissues (leaves, bark and root/pneumatophore) at two study sites of Indian Sundarban Wetland. The metal(loid) concentration in host sediments and their geochemical characteristics were also considered. Mangrove sediments showed unique potential i...

In this paper, we present a comprehensive morphological stability analysis of a single, epitaxially growing, perturbed circular island by using a Burton–Cabrera–Frank (BCF) island dynamics model. We show that there exists a critical deposition flux for which a single mode perturbation remains unchanged. In the absence of an additional far-field mass flux, there exists a naturally stabilizing ra...

Using a probabilistic risk-based framework, we have developed a simple predictive risk threshold model for protecting the survival of farmed abalone, Haliotis diversicolor supertexta, exposed to waterborne zinc (Zn). Probabilistic techniques using Monte Carlo analysis propagate parameter uncertainty/variability throughout the model, providing decision makers with a credible range of information...

In this study, we have studied the effects of temperature and X-ray energy variations on the light output signals from two different fiber-optic sensors, a fiber-optic dosimeter (FOD) based on a BCF-12 as a plastic scintillating fiber (PSF) and a fiber-optic thermometer (FOT) using a silver halide optical fiber as an infrared optical fiber (IR fiber). During X-ray beam irradiation, the scintill...

Clethra barbinervis Sieb. et Zucc. accumulates Nickel (Ni) and Cobalt (Co) at high concentrations., We hypothesized that C. barbinervis cannot distinguish between Ni and Co because of the similar chemical properties of these two elements. To confirm this hypothesis and understand the role of these elements in C. barbinervis, we conducted a hydroponic split-root experiment using Ni and Co soluti...

Selection of sunflower varieties with greater cadmium (Cd) tolerance and detecting physiological variation under different Cd concentrations are important to study the potential (Helianthus annuus L.) in phytoremediation Cd. The aim this was investigate among four (79−79, 363, 8361, ADT). Photosynthesis determined using a Li−6400 XT portable photosynthesis system. Inductively coupled plasma mas...

Iron is a transition metal capable of catalyzing redox reactions by generating free radicals. These free radicals generated damage cells by attacking cell membranes, proteins and deoxyribonucleic acids. This damage can occur in the beta cells of the pancreas leading to reduced insulin secretion and increased insulin resistance leading ultimately to abnormal glucose homeostasis and diabetes mell...

Mangrove wetlands serve as both a sink and source for arsenic (As), as mangrove plants are able to uptake and accumulate As. The present study used pot experiments to evaluate As accumulation and translocation in mangrove (Aegiceras corniculatum L.) seedlings grown in As contaminated soils. Results indicated that A. corniculatum seedlings grew normally under As stress with minute growth inhibit...

Available online 4 April 2008 How is corporate governance measured? What is the relationship between corporate governance and performance? This paper sheds light on these questions while taking into account the endogeneity of the relationships among corporate governance, corporate performance, corporate capital structure, and corporate ownership structure. We make three additional contributions...
