Capacitor-Probe Calibration and Optimization for NDE Application to Portland Cement Concrete
(Virginia Tech, 2000-08-28)
Three main objectives have been set for this research. The first is to develop an accurate method for measuring the dielectric constant of PCC using a capacitor probe (C-Probe) that has been recently developed at Virginia ...
Developing a cost effective construction and demolition waste management plan
(Virginia Tech, 1996-11-05)
Concern over construction and demolition (C&D) wastes is becoming a prevalent part of any construction project. Historically, landfilling waste materials was the standard solution for most contractors, but as tipping fees ...
Evaluating Ecological Influences of Altered Flow Regimes Using Two- and Three-Dimensional Hydrodynamic Models
(Virginia Tech, 2009-09-09)
Reservoir releases for generating power need to be reconciled with efforts to maintain healthy ecosystems in regulated rivers having irregular channel topography. Fluctuating, complex flow patterns near river obstructions ...
Emergency evacuation around nuclear power stations :a systems approach
(Virginia Tech, 1990-04-05)
Prior to this work, MASSVAC (MASS eVACuation) had evolved as a micro-computer simulation model for analysis and evaluation of areas facing natural disasters (hurricanes and floods). Conceptual and technical enhancements ...
The effects of nickel on the completely mixed activated sludge process
(Virginia Tech, 1979-04-05)
The purpose of this investigation was to conduct batch and continuous flow laboratory experiments with bench scale activated sludge units to determine the effects of nickel on the completely mixed activated sludge process. ...
Implications of P-Delta analysis and LRFD of gable frames
(Virginia Tech, 1990)
The Kinetics, Biochemical Patterns, and Microbial Ecology in Multiredox (Anoxic, Microaerobic, Aerobic) Activated Sludge Systems Treating BTX Containing Wastewater
(Virginia Tech, 1999-09-02)
BTX biodegradation rates, biochemical expression patterns and microbial ecology were studied under anoxic (denitrifying), anoxic/microaerobic/aerobic, and anoxic/microaerobic conditions in activated sludge sequencing batch ...
