oxisols evaluated in this study behaved as non-ideal exchangers and presented preferential adsorption of potassium over calcium for all proportions of these cations on the exchanger phase.
plumbeus catch was significantly reduced with the use of electropositive metals on longline hooks; however, preliminary laboratory investigations have demonstrated that juvenile C.
The repulsive and feeding deterrent effects of electropositive metals on juvenile sandbar sharks (Carcharhinus plumbeus).
A shocking discovery: How electropositive metals (EPMs) work and their effects on elasmobranchs.
Our studies are designed to determine if electropositive metals affect the behaviors of juvenile sandbar sharks (Carcharhinus plumbeus) under both laboratory and field conditions.
Our experiments with captive sandbar sharks include tests of the ability of electropositive metals to influence the swimming patterns of individual animals in the absence of food motivation and to repel sharks from pieces of cut bait.
According to the dualism theory, the substitution of an electronegative element like chlorine by an electropositive
one such as hydrogen should completely change the chemical properties of a substance.
It is malleable, ductile, slightly paramagnetic, strongly electropositive
and a poor electrical conductor .
He later suggested that the effect works in the opposite direction (the reverse anomeric effect for an electropositive
substituent at the anomeric centre, as might be expected if it is electrostatic in origin.
The results showed that the thermal stability of these samples was found to be dependent mainly on the electropositive
non- framework cations.
Electrochemical processes: For example, chlor-alkali process; production of electropositive
metals; corrosion; batteries; electroplating; electrolysis of water and a "hydrogen economy".
The disappearance of NH2 bond stretching at 2485 cm-1 of free ligand, in all the complexes indicate that cationic portion of the L-salt is detached, which in turn is replaced by more electropositive
