Enemy or foe is an individual or a group that is seen as forcefully adverse or threatening. The concept of an enemy has been observed to be basic for both individuals and communities.
A diffractometer (pronunciation: di-frak-'tÃ¤-m&-t&r) is a measuring instrument for analyzing the structure of a material from the scattering pattern produced when a beam of radiation or particles (such as X-rays or neutrons) interacts with it. Principle
One of the more common examples of the modern accelerometer is known as a MEMS device. Essentially, the MEMS or micro electro-mechanical system is a simple device that functions mainly with the use of a cantilever beam and circuits that are designed for the purpose of detecting the presence of deflection sensing.
