together with perspectives on the application of real space renormalization procedures to vortex methods based on We consider finite difference schemes based on the impulse density variable. We show that the original velocity—impulse density the impulse density. formulation of Oseledets is marginally ill-posed for the inviscid flow, At a first sight, the impulse density formulation also proand ...

Development and Characterization of High-Efficiency, High-Specific Impulse Xenon Hall Thrusters by Richard Robert Hofer Chair: Associate Professor Alec D. Gallimore This dissertation presents research aimed at extending the efficient operation of 1600 s specific impulse Hall thruster technology to the 2000-3000 s range. While recent studies of commercially developed Hall thrusters demonstrated ...

Gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. High specific impulse, good density and safety better than that of both solid and liquid propellants are advantages of the gel propellants. They are made by addition a suitable gellant to liquid propellants. In this research, nano Al particles have been used in UDMH gel fuel. The gel...

Ganglionic postsynaptic density protein (PSDp) was used to monitor the influence of transsynaptic impulse activity on synaptic structure in the developing and adult rat superior cervical sympathetic ganglion (SCG). Since transsynaptic activity is known to regulate ontogeny of postsynaptic transmitter enzymes, we initially studied the developing ganglion. Denervation in neonates prevented normal...
