Contact Temperature Sensor Types â These types of temperature sensor are required to be in physical contact with the object being sensed and use conduction to monitor changes in temperature. They can be used to detect solids, liquids or gases over a wide range of temperatures.
Mad cow disease is an incurable, fatal brain disease that affects cattle. Different versions of the disease can affect certain other animals, like goats and sheep. The medical name for mad cow disease is bovine spongiform encephalopathy (pronounced: BO-vine SPUN-jih-form en-seh-fah-LA-puh-thee), or BSE for short. It's called mad cow disease because it affects a cow's nervous system, causing a cow to act strangely and lose control of its ability to do normal things, such as walk.
Researchers believe that the infectious agent that causes mad cow disease is an abnormal version of a protein normally found on cell surfaces, called a prion. For reasons still unknown, this protein becomes altered and destroys nervous system tissue -- the brain and spinal cord.
