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...

Regulatory Issues Impacting the U.S. High-Level Radioactive Waste Management Program
This paper addresses current key regulatory issues impacting the U.S. high-level radioactive waste management program. The following issues pertain to the licensing of a geologic repository:...

Gaseous Release of Carbon-14: Why the High Level Waste Regulations Should be Changed
The high-level nuclear waste regulations pertaining to gaseous release of carbon-14 from a repository should be changed to allow greater release, for several reasons. Some of them are...

Isotopic Discontinuities in Ground Water Beneath Yucca Mountain, Nevada
Analytical data for stable isotopes in ground water from beneath Yucca Mountain, when examined in map view, show areal patterns of heterogeneity that can be interpreted in terms of mixing...

Strontium Isotopes in Carbonate Deposits at Crater Flat, Nevada
Strontium isotope studies of carbonates from soils, veins, eolian dust and Paleozoic basement sampled near Crater Flat, southwest of Yucca Mountain, provide evidence for the origins of...

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...

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,...

The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...

Transport of Volatile Organic Compounds (VOCs) Through a Clay Liner
A series of tests have been performed using laboratory-scale flexible wall permeameters. A synthetic organic leachate mixture of methylene chloride, toluene, and trichloroethylene (TCE)...

Interruption of Sewer Crown Corrosion—Ecological Solutions
Competitive inhibition of acid production by thiobacilli was investigated by encouraging the growth of potential competitors. Two-organism competition experiments (Thiobacillus sp. vs....

Magnetic Fluid Conditioning
Industry is now turning to develop magnetic water treatment in an effort to discontinue the use of chemicals. Magnetic water treatment takes a different approach to solving the same problem...

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...

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...

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...

Statistical Fatigue Properties of Carbon Steels for Machine Structural Use Based on JSMS Database on Fatigue Strength of Metallic Materials
A database on the fatigue strength of metallic materials was compiled by collecting the experimental fatigue data of the last 20 years in Japan on a nationwide scale as a joint project...

Fatigue Design and Reliability Analysis of CFRP Composites
The statistical fatigue properties of unidirectional (UD) T800/3631 carbon/epoxy composite laminates are investigated in this paper. Fatigue tests were conducted under rotating bending....

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....
