Robotic Options for Mining of Near-Earth Objects
The mining and processing of a Near-Earth Object (NEO) should be as simple and as robust as possible - the fewer processes and parts the better. Reliability and survivability of the total...

Nuclear Propulsion: Safety Measures and Concerns
Since nuclear fission was discovered, many potential uses for it have been found. One such application of fission is nuclear propulsion systems in space ships; however, the elements resulting...

Reduction, Reuse, and Recycling on a Future Lunar Base
The paper addresses the waste management problems on Earth as they relate to a future lunar base and suggests measures to prevent these problems from occurring in the base. Offensive action...

Biosphere II - Its Effects on Space Colonization
In the middle of the Arizona desert, a strange sight can be seen. A small world with ecosystems and different climate zones, just like Earth, is enclosed in glass and steel. The 3.15 acre...

Reducing the Long-Term Effects of Zero-Gravity
Maintaining the physical health of scientists has been a longstanding problem in space flight research. Several ideas have been proposed to solve this problem. These include creating artificial...

Living in Space
Living in space will be the key project for the survival of the human species in the future. The world is becoming more polluted, suffering under the lack of living space, and if people...

The Effect of Zero Gravity on Bones
Zero-gravity has created many problems for astronauts and researchers in space. Calcium depletion is cited as a major health problem. There are many different theories as to why zero-gravity...

Lunar Base Aspects for Biotechnology Industry
A lunar base can provide unique services to biotechnology research, development, and production. A lunar location as well as the vacuum environment can protect experiments from contamination...

Taking Trash Out of Hiding
Out of sight, out of mind has been the country's solid waste mind-set. But when the $18 million Phoenix Solid Waste Management Center becomes fully operational in April, visitors...

Assessing Effects for Disposal Sites off San Francisco
A simple particle tracking model has been used to estimate the size of deposition footprints and transient turbidity effects in the water column resulting from disposal of dredged material...

Nowcast System Development for the Straits of Florida
As part of the inaugural program for the Ocean Pollution Research Center at the University of Miami, a nowcast system is being developed for the Straits of Florida. The nowcast system...

The Politics of Nuclear-Waste Disposal
Spurred by federal and state legislation recommending local disposal of low-level radioactive nuclear waste, the Illinois-Kentucky Compact announced plans in the mid 1980s to build a disposal...

Federal Cleanups: Good News from Bad
Since the end of the Cold War the news about the Department of Energy has been grim: Thousands of acres poisoned with radioactive and toxic wastes, massive cleanup cost overruns due to...

Effects of Lateral Heading Flow Steadiness on Lateral Spillage
Hourly inflow and spillage rates from three lateral canals in the Imperial Irrigation District in Southern California were measured for seven months and subsequently analyzed to identify...

Denver's Direct Potable Water Reuse Demonstration Project
The Denver Potable Water Reuse Demonstration Project was created to provide definitive answers to the interrelated questions of product quality, public health, technical and economic feasibility,...

Robotics for Challenging Environments
This volume, Robotics for Challenging Environments, contains the papers presented at the ASCE Specialty Conference on Robotics for Challenging...

A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...

Decision-Making Paradigm for Risk Assessment of Hazardous Wastes Using Fuzzy Sets
This paper summarizes the development of a risk assessment framework to provide risk-cost policy alternatives to prioritize remediation actions for hazardous wastes. The framework is a...

Managing Uncertainty in Environmental Remediation Project Planning
The cleanup operations in environmental remediation (ER) process, a relatively new area of opportunity for the construction industry, is often avoided due to its perceived high risks....

Application of a Geographic Information System to Evaluate Environmental Hazards
The development of a Geographic Information System (GIS) application to evaluate potential environmental hazards within the Bushkill watershed in Northampton County, Pennsylvania, is described...
