Stair Nosing
Nosing is the horizontal, protruding edge of a stair where most foot traffic frequently occurs. Tread nosing The horizontal projection to the front of a tread where most foot traffic frequently occurs. The nosing is the protrusion beyond the riser when vertical risers are used, or beyond the back of the tread below, when angled risers or no risers are used. Anti-slip strips or nosings may be applied. These stair parts can be manufactured from a variety of materials including aluminum, vinyl, and wood. Landing nosing The landing nosing will often travel into the landing area to border the bottom of the balusters. The projection over the landing face will be the same as for the treads in the staircase. Nosing projection In timber flights, The nosing traditionally projects forward of the riser, the same distance as the thickness of the tread material. Safety Stair nosing, especially in commercial and industrial settings, are typically fitted with a non-slip surface to inc ...

Nose
A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face and serves as an alternative respiratory passage especially during suckling for infants. The protruding nose that completely separate from the mouth part is a characteristic found only in therian mammals. It has been theorized that this unique mammalian nose evolved from the anterior part of the upper jaw of the reptilian-like ancestors (synapsids). Air treatment Acting as the first interface between the external environment and an animal's delicate internal lungs, a nose conditions incoming air, both as a function of thermal regulation and filtration during respiration, as we ...
