Anomalous Concentrations Of Co-58 And Cs-137 In Dardanelle Reservoir, David M. Chittenden Ii
Anomalous Concentrations Of Co-58 And Cs-137 In Dardanelle Reservoir, David M. Chittenden Ii
Journal of the Arkansas Academy of Science
The unforseen occurrence of significant concentrations of Co-58 and Cs-1 37 in a quiescent backwater of Dardanelle Reservoir provided an opportunity to observe the equilibrium distribution of Cs-1 37 between solution and suspended solids. This equilibrium has not been observed in other areas of the reservoir because small amounts of this nuclide are regularly injected into the lake by the AP&L Nuclear I facility. The systematics of the Co-58 concentration lead to the conclusion that significant amounts of these two nuclides had been injected into the sampling area from a source unknown.

Electrochemistry Of Dihalogenated Nicotonic Acids In Aqueous And Aprotic Media, Ali U. Shaikh, Tappi A. Dixon, Lourie A. Battles, Frank L. Setliff
Journal of the Arkansas Academy of Science
The electrochemical reduction of several 2,5- and 5,6- dihalonicotinic acids have been studied in dimethyl sulfoxide as well as in aqueous buffers of different pH. The polarographic half-wave potentials for the reduction of these compounds in both media are reported here. The compounds appear to reduce at the carboxyl group. The presence of halogen atoms on the pyridine ring facilitates reduction.
