Pullulan for Advanced Sustainable Body- and Skin-Contact Applications

Leathers Biotechnological production and applications of pullulan

Pullulan is a unique biopolymer with many useful traits and hundreds of patented applications. However, despite the fact that pullulan has been in commercial production for more than 25 years, few of these potential uses have been widely adopted. In large part this may be due to the relatively high price of pullulan. Nevertheless, the last few years have seen a resurgence in interest in pullula...

Randomized Quadratic Programming with Applications to Rigid Body Contact

Motivated by applications in rigid body contact simulation we develop a numerically robust, randomized Quadratic Programming algorithm. We show that the resulting solver remains robust under highly constrained and redundant conditions, while also detecting infeasibility conditions. Its expected complexity is linear in the number constraints imposed and our experiments show that it performs well...

Pullulan-based nanoparticles: future therapeutic applications in transmucosal protein delivery.

Center for Advanced Sustainable Iron & Steel Making

Current blast furnace technology is a two-stage ironmaking process that requires that iron ore concentrate first be formed into pellets, fired at 1260°C, cooled, transported to the blast furnace, and then re-heated to approximately 1500°C to produce pig iron. This heating, cooling, and then reheating wastes a great deal of energy, which would be saved if the ironmaking process had only a single...

An Efficient Algorithm for General 3D-Seismic Body Waves (SSP and VSP Applications)

Abstract The ray series method may be generalized using a ray centered coordinate system for general 3D-heterogeneous media. This method is useful for Amplitude Versus Offset (AVO) seismic modeling, seismic analysis, interpretational purposes, and comparison with seismic field observations.For each central ray (constant ray parameter), the kinematic (the eikonal) and dynamic ray tracing system ...
