Reliability Synthesis of CFRP Laminated Plate
The paper presents a formulation of shift synthesis to improve the reliability of fiber reinforced plastic (FRP) laminated plates with uncertain elastic constants and lamina strength....

A Preliminary Model for Carbon-14 Transport in a Clay Buffer
A model has been developed to assess the effect of calcite dissolution and precipitation reactions on the transport of 14C through a saturated, calcite-containing...

Development of the Engineered Barriers for the Deep Geological Disposal of High-Level Radioactive Waste
Vitrified waste, overpack and buffer material are under research and development as engineered barriers in the deep geological disposal system of high-level radioactive waste. Static leach...

Origin of Carbonate Deposits in the Vicinity of Yucca Mountain, Nevada: Preliminary Results of Strontium-Isotope Analyses
As part of the paleohydrology study of the Yucca Mountain Project, strontium-isotope analyses of carbonate deposits, ground water, and major rock reservoirs of strontium are in progress....

Uranium-Series Dating of Secondary Carbonates Near Yucca Mountain, Nevada: Applications to Tectonic, Paleoclimatic, and Paleohydrologic Problems
Near-surface accumulations of secondary carbonates are common in the soils and sediments of the Yucca Mountain area. These carbonates contain small amounts of uranium that allow dating...

Requirements for Controlling a Repository's Releases of Carbon-14 Dioxide; The High Costs and Negligible Benefits
A repository excavated within the unsaturated zone may release carbon(C)-14 dioxide in amounts that exceed limits imposed by the Environmental Protection Agency (EPA) and the Nuclear Regulatory...

Removal of Scale from Potable Hot Water Systems by Carbon Dioxide Injections
An innovative method for inplace scale removal has been developed and demonstrated. Injection of carbon dioxide gas into a piping system can lower the pH of the hot water and remove or...

Calibrating the Chesapeake Bay Water Quality Model
A eutrophication model comprised of twenty-two state variables including three algal groups and multiple species of carbon, nitrogen, phosphorus, and silica is described. Equations governing...

Carbon Dioxide Release from OTEC Cycles
This paper presents the results of recent measurements of CO2 release from an open-cycle ocean thermal energy conversion (OC-OTEC) experiment. Based...

On the Road to Clean Air
Anticipating passage of the 1990 Clean Air Act in the fall of the year, this article examines the remaining air quality problems in U.S. cities and some efforts underway or being planned...

Bayesian Framework for Model Structure Uncertainty: Application to Sea-Level Response to Changing Global CO2

Foundation Engineering Constraints in Karst Terrane
Cavity-prone carbonate rocks are found in many Appalachian valleys and represent a poorly recognized hazard. This paper reviews the nature of the problem of founding above these Cambro-Ordovician...

Effect of Global Temperature Rise on the Coastlines of Bangladesh

Mass Balance Analysis of Decomposed Refuse in Laboratory Scale Lysimeters
Decomposition of shredded municipal refuse was studied under laboratory conditions with leachate recycle and neutralization. Cellulose and hemicellulose accounted for 91% of the methane...
