The Role of Phase Inversion in the Drug Release Kinetics of Injectable Polymer Solutions
… indicative of solid-liquid de-mixing and delayed burst release profiles. Depots with low degrees of crystallinity have dense morphologies formed by liquid-liquid de-mixing and slow, uniform release rates. In the third study, the effect of incorporating preferentially segregating additives into the …

Time dependent non-extinction probability for fast burst reactors
… Laboratories has successfully operated fast burst reactors over the past four decades. Fast burst reactors refer to a type of reactor that is able to achieve intense neutron pulses in very short periods of time using fissile material. Typically these systems are comprised of enriched metallic …

Evolution of an Acoustic Disturbance to Transition in the Boundary Layer on an Airfoil
… in the boundary layer using modulated acoustic bursts in the free-stream, and acquiring the mean boundary-layer data and fluctuating disturbance data using hot-wire probes. The acoustic receptivity due to surface roughness near Branch I has been examined. The surface roughness consisted of …

Biodegradable, Liquid-Filled, Spherical Capsules With Pre-Determined Burst Times
… as an internal program to achieve a delayed-burst release of its load. The capsule burst lag-time is accurately predicted by modeling the rate of water uptake by the capsule core as a function of the capsule shell thickness, radius of the capsule, core osmotic pressure and the membrane …

Lateral atlanto-dens interval variation in a normal South African population using Computed Tomography
… cervico-cranial junction, more specifically with burst-type fractures of the atlas with asymmetrical displacement of the lateral masses In our normal study group, no statistically significant difference between the left and right LADI measurements was demonstrable, allowing a region of statistical …

Tool wear monitoring in turning using fused data sets of calibrated acoustic emission and vibration
… a pulsed laser; the former produces continuous-type AE and the latter burst type AE. Since the air jet source has a power spectrum resembling closely the AE produced from single-point machining and since it is readily available in a machine shop, not to mention its relative safety compared to …

Triboemission From Ceramics: Charge Intensity and Energy Distribution Characterizations
… of tribopolymerization for some addition-type monomers is thought to be initiated and controlled by triboemitted low-energy electrons. This Ph.D. dissertation presents the experimental work carried out at the Virginia Polytechnic Institute and State University for the characterization of …
