[in′hib·əd·ər]
(aerospace engineering)
A substance bonded, taped, or dip-dried onto a solid propellant to restrict the burning surface and to give direction to the burning process.
(chemistry)

Inhibitor

 

a circuit having m + n inputs and a single output, at which a signal can appear only when there are no signals on the m inputs (inhibiting). The other n inputs (principal) form one of the two logic connections, “AND” or “OR.” Inhibitors are used extensively in computers. They are very often understood to be a circuit having a single principal input and a single inhibiting input. A signal appears at the output of such a circuit when a signal is present on the principal input but there is none on the inhibiting input. Such an inhibitor is called an anticoincidence gate; its conventional representation is given in Figure 1.

The new CHEI Web site will provide more versatility and efficiency regarding the loan draw and inspection process," says Mark Emmons, president of CHEI.
Once the MMSE falls below 10, most would consider initiation or continuation of therapy with ChEIs of no value to the patient.
ChEIs are commonly prescribed for AD, yet little is known about how their potential treatment effects might impact a driver's skills," said Lori Daiello, PharmD, a research associate at the Rhode Island Hospital Alzheimer's Disease and Memory Disorders Center (ADMDC).
