1 Rarely, fistulas occur externally to the skin or internally to another part of the biliary tree, to the pleural cavity or bronchial tree, or to the hepatic artery or portal vein or other vascular structures.
Load factor (aeronautics) In aeronautics, the load factor is defined as the ratio of the lift of an aircraft to its weight and represents a global measure of the stress (load) to which the structure of the aircraft is subjected: where: Since the load factor is the ratio of two forces, it is dimensionless.
Radial force variation is an industrial measurement term describing the tire uniformity under load, measuring the variation (up and down) of the load acting on the vehicle spindle (SAE practice J332). All tires have some non-uniformity in the sidewall and/or footprint due to variables in the manufacturing process.
