As peribronchial cuffing is a sign rather than a symptom or condition, there is no specific treatment except to treat the underlying cause.
Explain how a potential divider circuit can be used to produce a variable p.d. A potential divider is a circuit with at least two components (Câ, Câ)connected in series, with the output voltage taken across one of the components (Câ).
Physial vapor deposition (PVD) is a generic term for vacuum plating processes involving bombardment of the surface by energetic ions to enhance coating adhesion and improve coating structure. It is a common industrial process.olerances: PVD coatings are too thin to affect part tolerances, and in general will reflect the surface roughness of the base material. However, it is often necessary to plate the part surface with nickel and chromium prior to applying the PVD coatings. The combination can be thick enough to affect tolerances.
