Electron Beam Irradiation of Wastewater

An Assessment of Input Variables to the Penman-Monteith Equation Using Canopy Reflectance Measurements
Observing the form of the Penman-J.L. Monteith equation, it can be seen that several terms could be potentially estimated from remotely sensed data. These include: net radiation, canopy...

Operational Remote Sensing of Snow Cover in the U.S. and Canada
The Office of Hydrology of the National Weather Service maintains a cooperative National Operational Hydrologic Remote Sensing Center, based in Minneapolis, to generate remotely sensed...

Towards a Rainfall Estimation Using Meteosat Over Africa
The scope of the research is to develop a method of rainfall estimation at both small space and time scales (9 pixels -225 km2-, and single shower...

Selection of Marine Bioindicators for Monitoring Radioactive Wastes Released from Nuclear Power Plants
The Brazilian Nuclear Program comprises the Angra I Nuclear Power Plant, in operational tests; the Angra II Nuclear Power Plant, under construction, expected to be completed in 1992; and...

Occupational and Environmental Exposures to Radon: A Perspective for Mitigators
Occupational exposures to radon and radon decay products and the associated high incidence of radiation induced lung cancer form the basis for our present-day concern for limiting exposures...

Comparison of Preozonation and Prechlorination in the Treatment of Several Raw Water Supplies
Bench scale testing of 18 raw water supplies from various locations throughout the eastern United States was conducted to evaluate their susceptibility to ozonation, and to compare preozonation/conventional...

The Effect of UV Radiation on THM Formation in Drinking Waters
This study was undertaken to investigate the feasibility of using combined UV radiation/chlorination process in drinking water treatment for disinfection while producing lower concentrations...

Disinfection of Wastewater Effluents with Electron Radiation
A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons...

A Comparison of Reclamation Plans at Title I and Title II Uranium Mill Tailings Sites

Environmental Considerations for Lunar Base Engineering
Currently a large number of conceptual designs are being offered for the lunar base involving various types of structural materials and equipment for construction or resource recovery....

Sintering Lunar Simulants Using 2.45 GHz Radiation
In situ sintering of lunar regolith may be useful for slope stabilization, dust control, and other applications around a lunar base. Having a knowledge of the mechanical properties of...

A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...

Extraterrestrial Applications of Solar Optics for Interior Illumination
The major purpose of this paper is to introduce a terrestrial technology that we believe has potential extra-terrestrial applications. The technology is Solar Optics, which is subdivided...

Response of Advanced Composite Space Materials to Thermal Cycling
In addition to microgravity and lack of atmosphere, the space environment provides intense radiation of both penetrating and nonpenetrating types. This paper focuses on the cyclic radiational...

Radiation Hazards to Space Construction - The Energetic Particle Environments
Many aspects of the space environment are recognized hazards for activities above the Earth's atmosphere. One of the most dramatic hazards is that posed by the diverse energetic...
