Seven alternatives were evaluated to determine the most effective water supply strategy for the United Stares Marine Corp Air Station at the New River Water Treatment Plant, Camp Lejeune, North Carolina to ensure adequate flow, pressure and quality of potable water. It was determined that the No Action alternative was not acceptable due to plant deficiencies that have caused regulatory complian...

Desalination and water reuse technologies are critical for solving water problems. Unlocking water resources through the minimization of reverse osmosis (RO) concentrate volume offers sustainable opportunities to meet the challenge. A pellet softening lime intermediate concentrate chemical stabilization (ICCS) reactor and a conventional lime softening ICCS for the treatment of RO concentrate we...

This study is focused on anomalous strain-rate-dependent behaviour of bacterial cellulose (BC) hydrogel that can be strain-rate insensitive, hardening, softening, or strain-rate insensitive in various ranges of strain rate. BC hydrogel consists of randomly distributed nanofibres and a large content of free water; thanks to its ideal biocompatibility, it is suitable for biomedical applications. ...

The phonon dynamics of the Sn/Ge(111) interface is studied using high-resolution helium atom scattering and first-principles calculations. At room temperature we observe a phonon softening at the Kmacr; point in the (sqrt[3]xsqrt[3])R30 degrees phase, associated with the stabilization of a (3x3) phase at low temperature. That phonon band is split into three branches in the (3x3) phase. We analy...

Three-dimensional model binary glasses produced by quenching from a range of liquid temperatures were tested in shear over a range of strain rates using molecular-dynamics techniques. Tests were performed under constant volume and constant pressure constraints. The simulations revealed a systematic change in short-range order as a function of the thermal and strain history of the glass. While s...

The development of Wyoming’s energy resources (coal bed methane extraction [CBM], hydraulic fracturing) and carbon dioxide (CO2) sequestration sites all invariably result in the production of brackish wastewaters. The treatability of these waters varies from relatively simple for CBM water (dissolved solids < 2,000 mg/L) to complex for the water that is displaced during geologic sequestration o...

We present a model of the dynamical transition of atomic displacements in proteins. Increased mean-square displacement at higher temperatures is caused by the softening of the force constant for atomic/molecular displacements by electrostatic and van der Waals forces from the protein-water thermal bath. Displacement softening passes through a nonergodic dynamical transition when the relaxation ...
