The Right Tooele for the Job
Parker describes how the nation's largest chemical munitions destruction facility was designed and how it will operate. The U.S. Signed on to the Chemical Weapons Convention...
A Process Unit Based Approach to Media-Integrated Waste Minimization: A Paint Manufacturing Case Study
Research conducted at the School of Engineering, University of Guelph, has developed a media-integrated waste minimization plan for a major Ontario paint and coatings manufacturer. The...
Marine Engines Emissions for Vessels of the United States Coast Guard
A source testing project was conducted for a select class of ships of the United States Coast Guard (USCG). Pollutants quantified included nitrogen oxides (NOX), sulfur dioxide (S02),...
Toxic Air Emissions from Wastewater Treatment Facilities
Power Booster
With many utilities caught in a vise between semiobsolete facilities and demands for cleaner power, the $578 million Manchester Street repowering project is setting an example for an aging...
Acoustic Emission Monitoring of Fatigue Crack Growth in HSLA-80 Steel Box Beams
An acoustic emission is a transient elastic wave generated by the rapid release of energy from a localized source within a material. There can be many sources of acoustic emission in a...
California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...
Clearing the Air About Sludge Incinerator Emissions
In 1990, a research needs assessment for wastewater treatment agencies conducted by the Water Environment Research Foundation recommended a three-year project to identify and quantify...
Control of Odor and VOC Emissions at Wastewater Treatment Plants -Boston Harbor Case Study-
Siting of the new wastewater treatment plant (WWTP) for the Massachusetts Water Resources Authority (MWRA) in Boston was based on an assumption of mitigation of total reduced sulfur (TRS)...

Methodology for Determining Vehicle Usage and Speeds for Mobile Source Emissions Inventories
This paper was published by the Baltimore Regional Council of Governments to document its work in preparing data from its regional road model for input into a computer emissions inventory...
Signal Analysis for Quantitative AE Testing
Quantitative acoustic emission (AE) techniques can be used to monitor crack growth and to deduce microfracture mechanisms in quasi-brittle materials. Multichannel data acquisition systems...
Predicting Pollution
For urban areas struggling to meet the requirements of the 1990 Clean Air Act as well as state air-quality mandates, accurate forecasting of mobile emissions is critical to evaluating...
Evaluation of Neutron Emission from Vitrified HLW Compositions
Neutron radiological hazards from vitrified HLW are important for handling and transportation - especially if the concept of separate storage of concentrated transuranics is adopted, as...
High Speed Rail vs. Maglev in the Quebec City-Windsor Corridor: A Comparison of Energy Impacts and Emissions
This paper reports energy impacts and emissions for two high speed ground transportation systems that are considered for implementation in the Quebec City-Windsor Corridor (Canada). In...
Passive Acoustic Emission for Quantitative Evaluation of Freeze Thaw and Alkali Aggregate Reaction in Concretes
Several experiments are reported in which the progression of freeze thaw (FT), alkali-aggregate reaction (AAR), and internal cracking caused by mechanical loading were monitored using...
Damage Assessment in Concrete Using Acoustic Emission
An acoustic emission (AE) is a localized rapid release of strain energy in a stressed material. This energy release causes stress waves to propagate through the specimen. These acoustic...
Study of Three Dimensional Crack Tip Location of Mortar by Acoustic Emission
Plain mortar specimens were tested under three-point bending. Experimental variables include the width of the specimen and the notch-to-depth ratio. The experimental results of 12 specimens...
