Projects on the Czech List
The Czech Republic's increasing reliance on the European Community as a trading partner has created a need for airports, power plants, an improved telephone system, new highways,...

Small Systems Struggle
Across the U.S., small communities are caught in a bind. Local governments bear the primary day-to-day burden of caring for public works, responsible for 70% of the nation's...

Inner Harbor Wave Conditions due to Breakwater Overtopping
The results of this study have important application to the design of small boat marinas protected from incident waves by breakwaters that may be overtopped during extreme wave events....

Design, Construction, and Performance of a Baffled Breakwater
The Spud Point Marina breakwater is located within Bodega Harbor, a protected embayment on the northern California coast. Waves are attenuated by baffle panels hung between support piles....

Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...

Review of NPP Concrete Degradation Factors and Assessment Methods
Degradation of concrete in nuclear power plant (NPP) structures can be an age-related phenomena. Several research programs have been initiated by the U.S. Nuclear Regulatory Commission...

Controlling Nitrogen in Coastal Waters
Excess nitrogen in coastal waters is becoming a problem worldwide. Nutrients such as nitrogen come from sewage treatment plants, septic tanks, runoff from fertilizer and animal waste,...

On the Diffusional Stress Transmission
A probabilistic diffusional mechanism for the propagation of intergranular forces has been formulated as a set of three mathematical assumptions. The equilibrium equations are complemented...

The Feasbility of Using Solar Optics for Lunar Base Lighting
This paper is a summary of research conducted to establish the feasibility of using solar optics in reduced gravity environments, particularly a lunar base. The research was funded by...

Production of Oxygen by Electro-Reduction of Lunar Ores
Anorthositic Lunar ores contain approximately 42 wt. pct. of oxygen. An electrolytic dissociation of the ore can provide a rich source of gaseous oxygen with silicon, aluminum, calcium,...

Lunar Liquid Oxygen Production Facilities
Production of oxygen beyond Earth's gravity well has been shown to be an economic asset for interplanetary travel using chemical combustion propulsion. Requirements for lunar liquid oxygen...

Power Sources for Lunar Bases
Working and living on the Moon requires artificial power sources both to operate equipment and to maintain life. This paper briefly surveys the power sources designed or proposed to support...

Design Concepts for a Lunar Electric Power System
This paper discusses the results of ongoing research and the evaluation of various concepts for transmission, distribution and utilization of electric power for a lunar liquid oxygen plant....

A Mars 1 Watt Vortex Wind Energy Machine
Ever since Viking I and II landed on the surface of Mars in the summer of 1976, man has yearned to go back. But before man sets foot upon the surface of Mars, unmanned missions such as...

Polycrystalline CdTe Solar Cells for Large-Scale Space Applications
Solar cells are recognized energy sources for use in space. In this talk, the current status of polycrystalline CdTe solar cell development and the potential use of this technology for...

INTERLUNE Concept for Helium-3 Fusion Development
Many considerations suggest that in the 21st Century, deuterium/helium-3 (D-3He) fusion will be the electricity generation system of choice to replace...

Lunar He-3 Mining: Improvements on the Design of the UW Mark II Lunar Miner
One of the minor consituents of the solar wind which has been implanted in the lunar regolith over its several billion year history, is helium 3 (He-3), a rare isotope of helium which...

Beneficiation and Comminution Circuit for the Production of Lunar Liquid Oxygen (LLOX)
A complete lunar beneficiation and comminution circuit has been designed that requires no air or fluid locks for feed introduction or egress, with the exception of a vapor pyrolysis station....

Spiral Mining for Lunar Volatiles
Lunar spiral mining, extending outward from a periodically mobile central power and processing station represents an alternative for comparison with more traditional mining schemes. In...

Steam Injection System for Lunar Concrete
Since January 1989, the Department of Civil Engineering at the United States Air Force Academy has been conducting research on the use of concrete for constructing permanent facilities...
