Optimization of Hydroacoustic Deployments at John Day Dam

Description: This report describes short-term studies conducted in late November and early December 2001 to optimize hydroacoustic sampling techniques for John Day Dam before the 2002 fish passage efficiency (FPE) study. Knowledge gained in this study should significantly improve hydroacoustic sampling and the accuracy of estimates of fish passage at two locations that have presented problems in past studies. The spillway has been most problematic because many fish detected there were not entrained. Without… more

BRIGHT Lights, BIG City: Massive Galaxies, Giant Ly-A Nebulae, and Proto-Clusters

Description: High redshift radio galaxies are great cosmological tools for pinpointing the most massive objects in the early Universe: massive forming galaxies, active super-massive black holes and proto-clusters. They report on deep narrow-band imaging and spectroscopic observations of several z > 2 radio galaxy fields to investigate the nature of giant Ly-{alpha} nebulae centered on the galaxies and to search for over-dense regions around them. They discuss the possible implications for our understandi… more

Influence of Environmental Variables on the Susceptibility of Alloy 22 to Environmentally Assisted Cracking

Description: In its current design, the high-level nuclear waste containers include an external layer of Alloy 22 (NO6022). This material was selected to provide long-term corrosion resistance since if water enters in contact with the containers, they may undergo corrosion. The model for the degradation of the containers includes three modes of corrosion, namely general corrosion, localized corrosion and environmentally assisted cracking (EAC). The objective of the current research was to quantify the susce… more

Electrochemical Behavior of Alloy 22 in 5 M CaC12

Description: The corrosion resistance of Alloy 22 (UNS No.: N06022) was studied in 5 M CaCl{sub 2} electrolyte at various temperatures. Potentiodynamic polarization was used to examine the electrochemical behavior and measure the key potentials. Alloy 22 was found to be susceptible to localized corrosion in this high chloride [10M Cl{sup -}] environment at temperatures as low as 6O C.

Engineering index : a metric for assessing margin in engineered systems

Description: Inherent in most engineered products is some measure of margin or over design. Engineers often do not retain design and performance knowledge so they can quantify uncertainties and estimate how much margin their product possesses. When knowledge-capture and quantification is neither possible, nor permissible, engineers rely on cultural lore and institutionalised practices to assign nominal conditions and tolerances. Often what gets lost along the way is design intent, product requirements, and … more

Damage detection using frequency domain ARX models and extreme value statistics

Description: Structural health monitoring (SHM) is fast becoming a field of great importance as engineers seek for new ways to ensure the safety of structures throughout their designed lifetime. Current methods for analyzing the dynamic response of structures often use standard frequency response functions to model linear system input/output relationships. However, these functions do not account for the nonlinear response of a system, which damage often introduces. In this study, an auto-regressive model wi… more

The next generation of shared seismic models for R&D.

Description: We have created several elastic 2-D models and are currently defining a complex 3D elastic salt model for distribution to the international research community for use in the calibration of AVO, polarization filtering, tomography, multicomponent seismic analysis, converted wave tomography, and seismic attribute analysis. We have also obtained the release of several real 2-D data sets corresponding to the 2-D models to test the robustness of any new techniques. In addition to the synthetic seismo… more

Computational modeling and experimental characterization of indoor aerosol transport

Description: When a hazardous aerosol or gas is inadvertently or deliberately released in an occupied facility, the airborne material presents a hazard to people. Inadvertent accidents and exposures continue to occur in Los Alamos and other nuclear facilities despite state-of-art engineering and administrative controls, and heightened diligence. Despite the obvious need in occupational settings and for homeland defense, the body of research in hazardous aerosol dispersion and control in large, complex, vent… more

Performing Trade Studies in the CERCLA Environment

Description: During almost any project, situations will arise that require project management and/or engineering personnel to make choices regarding project direction or product development. Often these choices are simply a part of the normal engineering development cycle (e.g., refinement or optimization of the product design). Frequently, on Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and other similar projects, trade studies are initiated to address concerns or issues r… more

Surface Remediation in the Aleutian Islands: A Case Study of Amchitka Island, Alaska

Description: Amchitka Island, Alaska, was at one time an integral player in the nation's defense program. Located in the North Pacific Ocean in the Aleutian Island archipelago, the island was intermittently inhabited by several key government agencies, including the U.S. Army, the U.S. Atomic Energy Commission (predecessor agency to the U.S. Department of Energy), and the U.S. Navy. Since 1993, the U.S. Department of Energy (DOE) has conducted extensive investigations on Amchitka to determine the nature and… more

Russian Technology Advancements for Waste Mixing and Retrieval

Description: Engineers at the Mining and Chemical Combine nuclear facility, located in Zheleznogorsk, Russia, have developed a pulsating mixer/sluicer to mobilize a layer of consolidated, hardened sludge at the bottom of their 12-m-diameter by 30-m-high nuclear waste tanks. This waste has resisted mobilization by conventional sluicing jets. The new pulsating mixer/sluicer draws tank liquid into a pressure vessel, then expels it at elevated pressure either through a set of submerged mixing jets or a steerabl… more

Mechanisms and Determinants of RNA Turnover: Plant IRESs and Polycistrons for Metabolic Engineering

Description: There is a strong need for tools that allow multiple transgenes to be expressed in genetically engineered plants. For the last 30 years it has been believed that nearly all eukaryotic mRNAs were monocistronic, with ribosomes entering at the 5' end and scanning through the 5'UTR to the first AUG codon. It is now clear that perhaps 3% of vertebrate and yeast mRNAs utilize IRESs (Internal Ribosome Entry Sites) within their 5'UTRs to promote the internal entry of ribosomes to mRNAs and subsequent t… more
