Heavy Metal Transport in the Columbia River, British Columbia
Data on the total forms of selected metals were used to assess their concentrations at two sampling sites on the Canadian Columbia River from 1984 to 1989. Cadmium, the response variable...
Stochastic Finite Element Analysis of Metal Plate Connected Wood Trusses
A stochastic finite element approach is developed for use in ananlyzing metal plate connected wood trusses. The procedure uses linear beam-column elements to model the wood members. The...
Application of Probabilistic Approach for Crack Growth Damage Accumulation in Metallic Structures
Two stochastic crack growth approaches (i.e., 'general' and 'analytical') are presented and evaluated for predicting the crack growth...
Explosive Metal Working for Space
As the United States looks towards larger and larger lift vehicles for the transportation of the space station and other large payloads, the application of explosive metalworking becomes...
Inelastic Stability of Thin Walled Metal Tubes Under Cyclic Loading Conditions
This paper is concerned with an experimental investigation on the inelastic stability behavior of thin-walled tubular specimens of steel, aluminum and stainless steel, under cyclic loading...
Heavy Metals Sources and Waste Minimization for a POTW
This paper presents a summary of recent studies conducted to minimize heavy metals discharged to a South San Francisco Bay Publicly Owned Treatment Works (POTW). The studies identified...
Heavy Metals Pollution Monitoring Through the Critical Pathways Analysis: The Sepetiba Bay Case
The methodology of the critical pathway analysis has been widely employed to monitor the environmental impact of nuclear power plants in the aquatic environment. This methodology has been...
Coastlines of Brazil
These papers were presented at Coastal Zone '89 the Sixth Symposium on Coastal and Ocean management held in Charleston, South Carolina, July 11-14, 1989. This volume is a...
Comparison of the Third and Fourth Edition of the Guide: What is New and Different
The fourth edition of the 'Guide to Stability Design Criteria for Metal Structures' is a unique collection of ideas and information on stability problems. It...
Repair Welding of Arctic Offshore Structures and Vessels
This paper describes the welding procedure development for repair or field modifications of offshore drilling structures and vessels made with several different steel grades produced for...
Chromium Removal by Activated Sludge
The behavior of chromium (Cr) in a laboratory-scale, activated sludge process was evaluated. Both pH and the oxidation state of Cr were confirmed as critical parameters for evaluating...
Detoxifying Metal-Contaminated Solid Wastes by Induced Ion Exchange?A Theoretical Evaluation
The presence of minor amounts of insoluble heavy metal precipitates may render a large body of innocuous solids (say fly ash, soil, calcium carbonate or even biological sludge) potentially...
Remedial Action Alternatives for Groundwater Contamination
Preliminary remedial action alternatives are formulated for a site contaminated by heavy metals. The results of soils and hydrogeologic investigations are summarized and three corrective...
Prediction of Nutrient and Heavy Metal Transport Capacities of Suspended Sediment in the Southwestern United States
SEDCON, a computerized prediction technique (using forest type and geology as inputs) has been developed to estimate the impacts of land management practices on physical and chemical characteristics...
Allowable Metal Contaminant Levels in Landfilled Sludge
Disposal of municipal sludges in dedicated sanitary landfills can be environmentally acceptable. Contaminants within the sludge present the potential for public health risks but these...
Methodology of Determining Acceptable Levels of Heavy Metal Contamination in Municipal Sewage Sludge Applied to Cropland
The potential public health risks associated with the agricultural utilization of municipal sewage sludge dictate the development of environmentally acceptable criteria for the disposal...
Simplified Methods to Predict the Fate of Metals in Rives
Heavy metal contamination of rivers is of increasing concern to society. To help predict the fate of metals in rivers, researchers have developed computer models to simulate speciation...
Adsorption and Release of Heavy Metals in Contaminated Soil
This study investigated the adsorption and release rates of toxic metals in soil type associated with hazardous waste sites common to the Northeastern United States. Five heavy metals...
Pre-Engineered Metal Buildings: The Story Behind Their Rapid Growth
In 1964, pre-engineered metal buildings accounted for 24% of new non-residential, low-rise construction. By 1981, that figure had jumped to 56%. Behind that rapid growth are some very...
General Principles for the Stability Design of Metal Structures
The Structural Stability Research Council (SSRC) Technical Memorandum No. 5 is explored; this memorandum includes the general principles that form the bases of various SSRC recommended...
