Intuitionistic Logic with a “ Definitely ” Operator by Peter Mott January 1997
This paper introduces a logic ILED derived from standard intuitionistic sentence logic by adding two operators Dϕ for " Definitely ϕ " and ~ϕ for " Experience rejects ϕ ". A further negation ¬ϕ = def (ϕ→⊥) ∨ ~ϕ , which we call real negation, is introduced. Real negation is like intuitionistic negation when there are no D-operators but deviates when there are. We see that Dϕ ↔ ϕ is valid but ¬Dϕ...

Todetermine useful metrics for assessing streamwater quality in the Southeastern Coastal Plain, we examined differences among two buffered and three unbuffered streams in an agricultural landscape in southwestern Georgia. Potential indicators included amphibian diversity and abundance, aquatic macroinvertebrate populations, riparian vegetative structure, water quality, and stream physical param...

of the nitrogen cycling has major consequences for other biogeochemical processes and ecosystem functions and services, Voss says. Recent research has uncovered an apparent imbalance in the nitrogen budget of the oceans, which isn’t completely understood yet and may point to additional processes that remain to be discovered. The traditional view that bacterial denitrification is the only signif...
