ANESTHESIA PRODUCED BY DISTILLED WATER [PDF]

Journal of General Physiology, 1933
Cells of Nitella flexilis Ag. lose their power to respond to ordinary electrical stimulation after 2 or 3 days in distilled water. It returns after a day or so when they are replaced in their normal environment, in a suitable nutrient solution, or in a dilute solution of CaCl2.

Contribution of nitrification and denitrification to N2O emissions from urine patches [PDF]

, 2007
Urine deposition by grazing livestock causes an immediate increase in nitrous oxide (N2O) emissions, but the responsible mechanisms are not well understood. A nitrogen-15 (15N) labelling study was conducted in an organic grass-clover sward to examine the
