The Boom in In Situ Bioremediation
In situ bioremediation was first applied in 1972 when a subsurface release of high-octane gasoline threatened the water supply of a small town in Pennsylvania. Soluble inorganic nutrients...
Mother Nature's Pump and Treat
Known under the general term of phytoremediation, using vegetation as a remedial agent has existed in its basic form for many years, mostly in applications involving waste-water treatment....
SOS For Small-Town SSOs
No matter why a small town confronts its sanitary-sewer-overflow problems, solutions are bound by the town's own resources. For two Midwestern towns, hindsight shows that...
Geo-Environmental Issues Facing the Americas
Contamination of soil and ground water are problems common to developed as well as developing countries; their effects on health and the deterioration of natural resources transcend national...

Microtunneling Meets Mother Nature
The world's first ocean thermal energy plant is getting a double. Microtunneling the second ocean intake 80 ft under the Pacific Ocean is proving challenging, partly due to...
Rest in Peace
Engineers working on a subway connection project in the nation's capital successfully employed chemical grouting techniques--some never tried before--to protect a historically...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Journal of Infrastructure Systems
The ?Journal of Infrastructure Systems? publishes cross-disciplinary papers about managing, sustaining, enhancing, and transforming civil infrastructure systems. Papers are expected to contribute new knowledge...
Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...
Depressing Traffic Top-Down
Top down construction will permit the City and County of Denver to maintain traffic at two congested intersections while a tunnel is driven below them. The project, which will carry Speer...
Update of the Implications of Recent Space Resource Discovery
Immense resources have been discovered in the space near Earth during the last decade. Last August, 1992, one of the resource objects was discovered to contain a key ingredient that might...
Mineral Liberation and Beneficiation of Lunar High-Ti Mare Basalt, 71055: Digital-Imaging Analyses
Knowledge of the abundance of various lunar minerals and the ability to effectively beneficiate thee minerals are important requirements for effective utilization of lunar resources. SEM/EMP...
Kinetic Interpretations of First Reactivity Experiments on Lunar Basalt Samples
For the first time, water/oxygen production from Apollo program lunar samples has been experimentally demonstrated. The experiments gave extremely encouraging results as all ilmenite was...
Feasibility of Treating Synthetic Greywater by Culturing Waldmann's Dark Green Lettuce in a Hydroponic System
The objective of the research was to treat synthetic greywater in a hydroponic system culturing Waldmanns dark green lettuce (Lactuca Stavia L Var. Crispa L). The process is designed as...
Deepwater Waves and Tsunami Produced by the Impacts of Small Asteroids
Studies of ocean sediments may be used to determine when coastal areas have been hit by tsunamis in the past. Tsunami debris has been found to be associated with the Cretaceous-Tertiary...
Cut and Cover Construction of the SSC Injector Tunnels
The injector system of the Superconducting Super Collider (SSC) constitutes the string of tunnels where protons are accelerated to near the speed of light and injected into the main collider...
The Challenge of Housing the Largest Detector
The most innovative part of the structural-civil design of the Superconducting Super Collider (SSC) is that of the underground experimental halls located alongside the 86 kilometer collider...
