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.
Factors of safety, is also known as safety factor, is a term describing the load carrying capacity of a system beyond the expected or actual loads. Essentially, the factor of safety is how much stronger the system is usually that needs to be for an intended load. Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry load must be determined to a reasonable accur
