The invention comprises a topical compound preparation of sensitizing cream for application to the non-keratinized epithelium of a female, comprising a preparation of L-arginine and a preparation of menthol. Each inverter, in response to receiving the response requests, transmits a response to the controller at a randomly determined response time within the response time window. A determination is made as to whether a time at which the computer-based test is to be provided to the computer is within an approved time range. The second ends of the first and second panels are secured together in a tensile state such that the gate and the nursery items are securely held in place. The desiccant material captures moisture from the hopper atmosphere in order to promote the flowability of the bulk material.
