Abstract: A Computer Managed Learning System (CMLS) and process are provided by which an information database is produced by formatting the information to be learned into units; inputting the units of information into a computer system; storing the units of information in discrete locations on a storage media; and, assigning to each unit an Importance Rank, a provisional Individualized Difficulty Rank (IDR), a provisional Individualized Urgency Rank (IUR), a provisional Population Difficulty Rank (PDR) and a provisional Population Urgency Rank (PUR), which are also stored in discrete locations on storage media. When a student accesses the database, the student may elect to filter the units by specifying subject matter and/or ranges for IDR, Importance-rank and IUR, or combinations or permutations thereof. The system selects the appropriate units from the database according to the filtering criteria input by the student.

Abstract: A method and a device for repelling pit vipers (rattlesnakes, copperheads, water moccasins) and boids (pythons, anacondas, boa constrictors) are disclosed whereby the snakes are irradiated with IR radiation having an appropriate wavelength and intensity to stimulate the IR-receptors of the snakes, thereby “jamming” the IR-receptors and/or producing an inimical electromagnetic environment that the snakes cannot tolerate.
