Regeneration?Potentially Powerful Stuff
Virtually all Automated People Movers (APMs) use electrical power for propulsion. Many designs also use electrical braking to augment any mechanical braking devices for decelerating trains....
Speedy Backfilling for Old Mines
In November 1992, the U.S. Bureau of Mines, in cooperation with the Office of Surface Mining (OSM), used two recently-developed pneumatic backfilling devices to completely fill an abandoned...
Lost & Found: Comeback at the IDB
With the lost decade of the 1980s behind it, Latin America has emerged from its debt crisis as a project powerhouse. Fueling many of those projects is the Inter-American Development Bank...
Back to Iran
Surprisingly to some, Iran continues to rank among the attractive markets of the Middle East. Despite political and economic problems, it is a large market, its location makes it strategically...

The Hazard In Using Probabilistic Seismic Hazard Analysis
Probabilistic seismic hazard analysis has been used extensively for major dams; nuclear power plants; liquefied petroleum gas installations; repositories for dangerous wastes; sensitive...
Letter from Oman
The bonanza days of the 1980s are over, but the oil-rich sultanate continues to be a rewarding, if challenging, market. Oil remains a focus of investment, and the government is planning...
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,...
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...
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...
