Disclosed herein is a process for the manufacture of 2–1-cyclopentylamine by low-pressure hydrogenation of 1-amino-2-cyano-1-cyclopentene using a combination catalyst system of nickel with palladium on carbon, or a single palladium-doped Raney-type catalyst. Methods and kits according to the invention include an animal or plant species in diapause. If the resource is unreserved, then accessing the resource by reading the resource timestamp to detect any changes in the timestamp since the last reading; if unchanged, then accessing the resource. In another embodiment, the costs of the peripheral links are adjusted commensurate with the volume of peripheral link traffic. The movable core has a nonmagnetic layer formed on an outer surface thereof and having a predetermined thickness.
