Waste Containment Facilities
This book presents a comprehensive description of recommended procedures for construction quality assurance (CQA) and control (CQC) for waste containment facilities. Chapter 1 describes...

Designing for the First Flush
This article explains some of the details involved in separating the first flush of a storm event from the remainder of the storm. It also explains how to provide primary treatment of...

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...

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...

JSC-1: A New Lunar Soil Simulant
A new lunar soil simulant, JSC-1, has been developed and characterized under the auspices of the NASA Johnson Space Center. This simulant was produced in large quantities to satisfy the...

A Simple Method of Producing Lunar Soil Simulants for Engineering Studies
This paper suggests that it is possible to obtain large quantities of simulated lunar regolith that can be used for feasibility studies of lunar base construction and excavation machinery...

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...

Reservoir Estimates for the Sulpicius Gallus Region
Estimates presented here show that 1.1?10⁹ metric tons of oxygen could of produced from one of the enriched areas that have been detected by spectrographic...

Utilization of Liquid Carbon Dioxide for Planetary Exploration
The major component of the atmosphere of Venus and Mars is carbon dioxide CO₂. This proposal is to use this carbon dioxide for planetary exploration...

Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...

Terrestrial Analogs: Implications for Lunar Lava Tubes
Earlier work has demonstrated that lava tubes did form on the Moon. Comparison of terrestrial lava tubes to their lunar counterparts suggest that they are very similar despite the order...

Lunar Oxygen Production - A Maturing Technology
Research on oxygen production from lunar rock and soil has made significant progress in the past two years. An extensive series of experiments on natural and synthetic analogs has concentrated...

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...

Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...

Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...

Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...

Oxygen from Lunar Soil via Fluorination
This paper considers oxygen extraction from lunar soil via fluorination, for reasons of its high effectivity of oxygen release from most silicates. In addition to theoretical investigations,...

Sintering Bricks on the Moon
Sintering of full-scale 'bricks' from lunar soil simulant materials can be accomplished by radiant heating to 1100?C for approximately 2 hours, followed by slow cooling. Small-scale precompaction...
