Preliminary National Evaluations of CO2 Emission Controls
Under the aegis of the International Energy Agency, several countries have begun making comparable studies of the cost-effectiveness of various measures to reduce emissions of carbon dioxide...

Exploring CO2 Emissions Reduction Strategies
Concern for potential climate change resulting from the greenhouse effect may be the biggest factor in energy planning in the 1990s. A 20% reduction in CO2,...

Electric Utility Planning for Greenhouse Concerns
International concerns for the potential of significant climate change resulting from the greenhouse phenomenon have focused increasing attention on the emissions of carbon dioxide and...

Designing for Corrosion Control
This presentation will discuss designing from several aspects: a. Designing of the item to lessen the affects of corrosion. b. Selection of non-corrosive materials in the designing process...

Potential ¹4CO2 Releases from Spent Fuel Containers at Yucca Mountain
The potential release of gaseous 14CO2 from small perforations in spent fuel containers has been evaluated...

Distribution of Rubidium, Strontium, and Zirconium in Tuff From Two Deep Coreholes at Yucca Mountain, Nevada
Variations in concentrations of trace elements Rb, Sr, and Zr within the sequence of high-silica tuff and dacitic lava beneath Yucca Mountain reflect both primary composition and secondary...

Responses of Benthic Macrofauna to Phaseout of Sewage Sludge Disposal in the Inner New York Bight
From 1924 through 1987, sewage sludge was dumped at the '12 mile site' 22 km off northern New Jersey in the inner New York Bight. Inputs in the early 1980s were,...

Separation of Organics from the Aqueous Phase Using Polymeric Resins
The adsorption of tetrachloroethene (PCE) onto several polymeric materials is reported and compared to activated carbon F-400. In addition, the bisolute adsorption of chloroform and trichloroethene...

Composite Materials Show Promise for Clean Kaplan Runners
In order to prevent any possibility of oil leakage into river water, LMZ manufactured Kaplan runners containing oil in the blade servomotor only, while the blade operating mechanism operates...

Evaluation and Rehabilitation of Clogged Drains at Concrete Gravity Dams
Studies have shown that properly spaced drains of adequate depth provide the principal means of relief from uplift pressures beneath concrete gravity dams. Drains often become encrusted...

Regional Estimates of Gas Transfer Using an Airborne System
The aircraft-based eddy correlation technique was recently used to obtain regional observations of transfer processes of sensible and latent heat as well as carbon dioxide over wetlands...

Carbon Dioxide Pressure in Surface Waters of Canadian Lakes
Direct measurements of the partial pressure (pCO2) of carbon dioxide were made in lakes of three study areas: ELA (the Experimental Lakes Area) and...

Oceanic CO2 Uptake and Future Atmospheric CO2 Concentrations
The global pattern of water column inventories of bomb-produced 14C suggests that an upwelling of bomb 14C-free...

Hydrodynamics and Mass Transfer in a Jet-Agitated Vessel
Experiments of carbon dioxide absorption in water have been carried out in a turbulent vessel presenting a zero mean shear stress value at the gas-liquid interface. Liquid-phase turbulence...

CFRP Cables for Large Structures

An Evaluation of Evidence Pertaining to the Origin of Vein Deposits Exposed in Trench 14, Nevada Test Site, Nevada
Large vein-like deposits of calcite and opaline silica that infill the Bow Ridge fault are exposed by Trench 14 at the Nevada Test Site. The origin of the deposits has been the center...
