Monitoring of a Gas Main During Construction
This paper focuses on the task of formulating and implementing a viable plan for protecting an existing gas main located in a construction site where construction activities include excavation,...
Trenchless Techniques for Pipeline Installation, Renovation and Replacement
New construction methods have been developed primarily in Europe and Japan for underground pipeline work. The new methods, known as trenchless techniques, are primarily used when existing...
Gas Transfer at the Water Surface: Measurements of Gas Concentration Fluctuations
The paper describes measurements of fluctuating gas (oxygen) concentrations by means of a polarographic microscope near the air-water interface. The objective is to demonstrate the feasibility...
Transportation by Pipelines in Space Colonies
The use of pipelines in space colonies to transport liquid, gas, solids and even passengers is not only feasible but also desirable. For many applications, pipelines offer a number of...
Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...
Seismic Risk to Natural Gas and Oil Systems
This paper begins with a brief summary of significant earthquake damage to gas and oil lifeline systems during several earthquakes. Following this discussion, the objectives and major...
Zapping Hazwastes
Electromagnetic energy, applied in situ, successfully removes contaminants entrapped in soil by vaporizing them. Recent test using radio frequency have successfully removed up to 99% of...
Radon at Home
Radon-222 is a radioactive gas that is present in all homes and found in several million homes in the U.S. at levels that have medical experts concerned about its potential to cause lung...
Techniques for Delineating Subsurface Organic Contamination: A Case Study
Selection of techniques to detect and map subsurface organic contamination depends on the type of source, contamination, and hydrogeologic setting. Ideally, an investigator, manager, or...
