The patterns of uptake, retention, and tissue distribution of
⁹⁵mTc in two freshwater species, the crayfish Pacifastacus
leniusculus and the snail Juga silicula have been investigated. The
animals were chronically exposed in water to which sodium
pertechnetate had been added. Final whole-body concentration ratios
(CR) obtained were 1.6 and 41...

The increasing knowledge of the significance of vitamin B₆ in
human metabolic processes has emphasized the importance of developing
reliable means of assessing nutritional status with respect to
this vitamin. One possible approach to this end is the measurement
of pyridoxal phosphate in blood or plasma, particularly since this
phosphorylated...
The need to identify a simple but accurate method of stripe rust assessment that best predicts host response prompted this investigation. The study was divided into two plot types, one protected with the fungicide Bayleton and the other unprotected. Ten winter wheat cultivars were used and evaluated. Grain yield, test...
Racial, ethnic and gender diversity have been long term topics of discussion in natural resources.
