Over the years , data provided by the program have been instrumental in modeling and predicting many important scientific systems such as combustion chemistry , atmospheric changes related to ozone depletion and warming , plasmas , and free-radical chemistry . Therefore , simultaneous spectroscopic observations in the NIR and X-ray bands can readily test the model , which , if proven to be valid , may be used to determine the evolution of the plasma properties during an eruptive event with spectroscopic observations in either band or simultaneous flux density measurements in both bands . Pulsed-plasmas have the plasma source turned on-and-off periodically , while ion-ion plasmas have only positive and negative ions in them and no electrons . These projects will focus on such fundamental phenomena as electromagnetic wave-plasma interactions , plasma turbulence and macroscopic stability of magnetically confined plasmas . Plasma Physics : In experimental plasma physics , research is being conducted on ( 1 ) equilibrium , stability , and transport in fusion plasmas : high-beta tokamaks , spherical tokamaks , and levitated dipoles ; ( 2 ) magnetospheric physics : trapped particle instabilities and stochastic particle motion ; ( 3 ) confinement of toroidal nonneutral plasmas ; ( 4 ) plasma source operation and heating techniques ; and ( 5 ) the development of new plasma measurement techniques . Third , the AABB believes that there is no need to distinguish between recovered plasma and source plasma based on donor suitability . Issue enough units of FFP ( Fresh Frozen Plasma ) for a 20 year old kid who was burned by the exploding gas-tank of a hillbilly-armored humvee that was taken out with a three-pound IED to the back axle , and the seeds of loathing find fertile soil . I and my students have developed several diagnostics for studying these plasmas and consequently have extensive experience in determining plasma kinetics . I believe quite firmly that the sun is a large ball of plasma , 98 million miles from the Earth , which generates energy by means of fusion . We employ argon plasma source magnetic sector mass spectrometers equipped with a variety of sample introduction devices .
