Aerospace engineering is the branch of Engineering behind the design construction and science of Aircraft and Spacecraft. Human Feces (also faeces &mdash see spelling differences) also known as stools, is the waste product of the human digestive system and varies significantly Defecation is the final act of Digestion by which organisms eliminate solid semisolid or liquid Waste material ( Faeces) from the Digestive tract

A radio-frequency identification tag ingested by livestock is also referred to as a bolus. Radio-frequency identification ( RFID) is an automatic identification method relying on storing and remotely retrieving data using devices called RFID tags or It remains in the stomach of the animal for its lifetime and emits a unique ID that can be used to track an animal.
