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.
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. f L o a d = Average load Maximum load in given time period {\displaystyle f_{Load}={\frac {\text{Average load}}{\text{Maximum load in given time period}}}}.
