Distributorless ignition systems (DIS) have been around for almost a decade now, and have eliminated much of the maintenance that used to be associated with the ignition system. No distributor means thereâs no distributor cap or rotor to replace, and no troublesome vacuum or mechanical advance mechanisms to cause timing problems.
Olfactory sensitivity is directly proportional to the area in the nasal cavity near the septum reserved to the olfactory mucous membrane, which is the region where the olfactory receptor cells are located. The extent of this area is a specific between animals species.lfactory sensitivity is directly proportional to the area in the nasal cavity near the septum reserved to the olfactory mucous membrane, which is the region where the olfactory receptor cells are located.

The sense of smell is technically known as olfaction. In man the olfactory organ is the superoposterior area of the nasal cavity, including part of the nasal septum and the two turbinate bones, which protrude from the lateral walls of the cavity.The entire olfactory organ is covered by the olfactory epithelium, whose surface area is about 5 cm 2.he sense of smell is technically known as olfaction.
