Abstract: A moisture content sensing system is described comprising a collar mechanically coupled with a clean grain transport system. An extendable support extends through the collar and has an extendable capacitive sensor element disposed at one end. The extendable support is configured to be located at a first position in which the extendable capacitive sensor element is disposed adjacent to clean grain conveyed by the clean grain transport system and moved to a second position wherein the extendable capacitive sensor element is disposed at least partially within the clean grain of the clean grain transport system.

Abstract: Duplex polynucleotides containing damage or errors are detected with hindered intercalating compounds which are capable of intercalating only in the presence of such damage or error. Conditions characterized by the presence of polynucleotide errors or damage are treated with such compounds that are capable of catalyzing polynucleotide cleavage with light.
