Disposal of sandy pipeline dredge spoils by end dumping

Creator:: Pyles, Marvin Russell
Abstract:: Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

Experimental studies of Vierendeel beam analysis

Creator:: Russell, William Clyde
Abstract:: Fabricated steel beam specimens with rectangular holes cut in the webs were subjected to load tests to analyze the behavior of the modified section. Beam-depth to hole-depth ratio was in all cases 2.0; however, ratio of hole length to hole height varied from 2.0 to 3.0. The primary instrumentation of...

Development of structural layer coefficients for open graded asphalt emulsion mixes

Creator:: Hatch, David Russell
Abstract:: This paper describes the development of structural layer coefficients for open graded asphalt emulsion surfacing layers which can be used with the AASHO pavement design method, as modified by the U. S. Forest Service, Region 6. A field survey conducted to document the history, performance and material characteristics of in-service...

Effects of substrate interactions, toxicity, and bacterial response during cometabolism of chlorinted solvents by nitrifying bacteria

Creator:: Ely, Roger L.
Abstract:: Cometabolic biodegradation processes, important for bioremediation of hazardous waste sites, are not well understood and have not been modeled thoroughly. Toxic effects and bacterial responses to toxicity may change intracellular enzyme levels, rendering traditional enzyme kinetics models inappropriate. This document presents a novel cometabolic enzyme kinetics model that incorporates enzyme...

Structural Response of High-Performance Fiber-Reinforced Cementitious Composites: Evaluation, Simulation, and Sensitivity Analysis

Creator:: Khlef, Feras L.
Abstract:: The constitutive behavior of high-performance fiber-reinforced cementitious composites (HPFRCCs) under mechanical loading is characterized by significant tensile properties that play an essential role in the structural response of several applications in structural engineering. The significance of tensile properties of HPFRCCs in structural engineering is the focus of three manuscripts presented...

Startup and performance of a gas-permeable-membrane-supported (GPMS) biofilm system using a mixed culture of methylotrophs to degrade methylene chloride, chloroform, and carbon tetrachloride

Creator:: Ely, Roger L.
Abstract:: The methane monooxygenase (MMO) enzyme, used by methylotrophs to oxidize methane, has been shown to possess quite broad substrate specificity, being able to oxidize many organic compounds including n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and heterocyclic compounds. In this research, it was sought to determine whether a gas-permeable-membrane-supported (GPMS) biofilm...

A method of PCB metabolite determination in anaerobic freshwater sediments using a upflow anaerobic biofiltration process (ANBIOF)

Creator:: Low, Edmond J.
Abstract:: The biodegradation of five polychlorinated biphenyls (PCBs) by Hudson River and Silver Lake sediments was studied using gas chromatography with electron capture detection (GC/ECD) and gas chromatography with mass spectrometry (GC/MS) analyses. Methanogenic sediments from the Hudson River and Silver Lake were used to inoculate four anaerobic filter reactors. The...

Down-borehole permeable barrier reactor : primary substrate selection for aerobic dichlorophenol degradation

Creator:: Kaslik, Peter J.
Abstract:: In situ bioremediation of pentachlorophenol-contaminated ground water in a sequential anaerobic-aerobic down borehole permeable barrier reactor requires a non-toxic primary substrate for dichlorophenol cometabolism. Serum bottle tests comparing the effectiveness of eight primary substrates for aerobic dichlorophenol degradation showed phenol to be the most effective followed by imitation vanilla flavoring,...

A manual for plate loading tests performed on rock

Creator:: Dodds, Donald J.
Abstract:: Plate loading tests in rock are deceptively simple tests to perform. Consequently, many varieties have been developed in the past 60 years. From each of the varieties various investigators have added their own developments and modifications, some good, and some not so good. The result has been a confusion of...
