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...

Static and Dynamic Properties of Gravelly Soils
The behavior of gravelly soils has been the focus of much research in recent years. Large-scale penetration and triaxial tests, shear-wave velocity measurements, insitu freezing and sampling,...
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...
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...
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...
Real-Time Control for a Robotic Rebar Bender
Job conditions and variability in the properties of the stock material combine in a rebar bending operation to create a challenging environment for a robotic bender. This paper reports...
On the Dynamics and Control of Flexible Orbiting Systems: An Approach with Application
A relatively general formulation for studying the dynamics and control of an arbitrary spacecraft, with interconnected flexible, deployable and articulating structural members, is reviewed...
Thermoelastic Theory of Cylindrical Sandwich Shells with Piezoelectric Sensors or Actuators
Cylindrical sandwich shells with piezoelectric longitudinal and ring elements bonded to the outer and inner surfaces are considered in this paper. Thermal effects are included in the analysis,...
Mechanics of Curved Fiber Bundles in Composites
Fiber undulations are inherent to manufacturing processes like braiding and filament-winding, and sometimes occur as defects in other composite structures. This paper summarizes the status...
Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [02/906]s...
Thermal Cycling of Thin and Thick Ply Composites
An experimental study was conducted to determine the effects of ply thickness in composite laminates on thermally induced cracking and changes in the coefficient of thermal expansion (CTE)....
Development, Testing and Modeling of Ceramic Composites for Lunar Applications
The procedure referred to as thermal liquefaction allows production of Intermediate Ceramic Composites (ICC) from lunar simulants with various admixtures. For their use as structural materials...
Methods to Mitigate Thermally Induced Distortion
The purpose of this paper is to show the magnitude of bending on the Space Station Freedom Navigation Base as induced by thermal expansion and contraction over the operating range -45...
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...
