This paper deals with the toxicity of mercuric chloride to different ATPases in the intestine of mudskipper (Boleophthalmus dentatus). Mudskippers were exposed to four sublethal concentrations of mercuric chloride for three durations. The specific activities of Na+, K(+)-ATPase, Ca(2+)-ATPase, Mg(2+)-ATPase, Ca2+, HCO3(-)-ATPase, and Mg2+, HCO3(-)-ATPase(More)
A technique to derive test vectors that exercise the worst-case delay effects in a domino circuit in the presence of crosstalk is described. A model for characterizing the delay of a domino gate in the presence of crosstalk is developed and exploited by a new efficient timing analysis algorithm. The algorithm uses a single, breadth-first traversal to(More)
The coastal teleost species, Periophthalmus dipes, commonly known as the mudskipper, was exposed to three sublethal concentrations (5, 10 and 15 mg/l) of potassium chromate for three exposure durations (2, 4 and 6 days). The study compares the dose- and duration-dependent effects of Cr(VI), as potassium chromate, on the ATPase systems in various organs of(More)
In the present study, a small fresh water aquatic ecosystem was created into a small test tank to evaluate the movement and bioaccumulation of Cr (VI) through water, sediment, a macrophyte Hydrilla, small fish guppy, and few key organs of magur, Clarias batrachus. The Cr (VI) intoxication was imposed of as a single dose of 30 mg/l concentration for a wide(More)
