91Magnetic field oscillating amplified thruster — The Magnetic Field Oscillating Amplified Thruster (MOA) (often named as Plasma Engine by the media) is a versatile electrothermodynamic system, which is able to accelerate nearly every medium to extremely high velocities, thereby generating a… …
92mass spectrometry — or mass spectroscopy Analytic technique by which chemical substances are identified by sorting gaseous ions by mass using electric and magnetic fields. A mass spectrometer uses electrical means to detect the sorted ions, while a mass spectrograph …
93Law, Crime, and Law Enforcement — ▪ 2006 Introduction Trials of former heads of state, U.S. Supreme Court rulings on eminent domain and the death penalty, and high profile cases against former executives of large corporations were leading legal and criminal issues in 2005.… …
94Nobel Prizes — ▪ 2009 Introduction Prize for Peace The 2008 Nobel Prize for Peace was awarded to Martti Ahtisaari, former president (1994–2000) of Finland, for his work over more than 30 years in settling international disputes, many involving ethnic,… …
95Internal combustion engine — The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine, the expansion of the high temperature and high …
96Rocket propellant — is mass that is stored, usually in some form of propellant tank, prior to being used as the propulsive mass that is ejected from a rocket engine in the form of a fluid jet to produce thrust.Chemical rocket propellants are most commonly used,… …
97Antenna measurement — techniques refers to the testing of antennas to ensure that the antenna meets specifications or simply to characterize it. Typical parameters of antennas are gain, radiation pattern, beamwidth, polarization, and impedance.The antenna pattern is… …
98Ion thruster — An ion thruster is a form of electric propulsion used for spacecraft propulsion that creates thrust by accelerating ions. Ion thrusters are characterized by how they accelerate the ions, using either electrostatic or electromagnetic force.… …
