Activation of cobalt by neutrons from the Hiroshima bomb

Description: A study has been completed of cobalt activation in samples from two new locations in Hiroshima. The samples consisted of a piece of steel from a bridge located at a distance of about 1300 m from the hypocenter and pieces of both steel and concrete from a building located at approximately 700 m. The concrete was analyzed to obtain information needed to calculate the cobalt activation in the two steel samples. Close agreement was found between calculated and measured values for cobalt activation … more

Application of neural nets to system identification and bifurcation analysis of real world experimental data

Description: We report results on the use of neural nets, and the closely related radial basis nets'', to analyze experimental time series from electro-chemical systems. We show how the nets may be used to derive a map that describes the nonlinear system, and how reserving an extra input line'' of the network allows one to learn the system behavior dependent on a control variable. Pruning'' of the network after training appears to result in elimination of spurious connection weights and enhanced predictive … more

An Assessment of Freeze Brand and PIT Tag Recovery Data for Juvenile Salmonids at McNary Dam, 1988 Annual Report.

Description: This study evaluated mark recovery data from PIT-tagged and freeze-branded river-run yearling and subyearling chinook salmon (Oncorhynchus tshawytscha), sockeye salmon (Q. nerka), and steelhead (0. mykiss) at McNary Dam in 1988. Double-marked (PIT-tagged and freeze-branded) juvenile salmonids were released within the McNary Dam collection system upstream from the PIT-tag detectors and brand sampling system. Results indicate that brands were recovered in smaller proportions than PIT tags and the… more

Biological Manipulation of Migration Rate: The Use of Advanced Photoperiod to Accelerate Smoltification in Yearling Chinook Salmon, Annual Report 1988.

Description: Research was conducted to assess the feasibility of biologically manipulating physiological development and migratory behavior of yearling spring chinook salmon, Oncorhynchus tshawytscha. At Dworshak National Fish Hatchery a treatment group was exposed to a 3-month advanced photoperiod cycle for 14 weeks preceding release. Physiological development and migratory performance of this group was compared to a control group. Changes in physiological indices indicated that exposing fish to an advance… more

Bunch lengthening in the SLC (Stanford Linear Collider) damping rings

Description: A high level of current dependent bunch lengthening has been observed on the North damping ring of the Stanford Linear Collider (SLC). At currents of 3 {times} 10{sup 10} this behavior does not appear to degrade the machine's performance significantly. However, at the higher currents that are envisioned for the future one fears that its performance could be greatly degraded due to the phenomenon of bunch lengthening. This was the motivation for the work described in this paper. In this paper we… more

Causes of failing the draft ANSI Standard N13. 30 radiobioassay performance criterion for minimum detectable amount

Description: The test methods used for PNL bioassay performance tests were evaluated by comparing the MDA based on performance tests results with MDA calculated by PNL using the bioassay laboratory's own quality control (QC) data. Two in vitro laboratories and two in vivo laboratories were studied and a correlation between the performance test MDA estimates and QC data was demonstrated. However, it was often necessary to examine the QC data to identify important characteristics of the blank distributio… more

Cle Elum Lake Sockeye Salmon Restoration Feasibility Study, 1987-1989 Progress Report.

Description: This report summarizes research activities conducted by the National Marine Fisheries Service (NMFS) from July 1988 through March 1989 relating to the Cle Elum Lake sockeye salmon restoration feasibility study. During this period, efforts focused on collection and spawning of adult sockeye salmon from the Wenatchee River, incubation of eggs from the 1988-brood, and the rearing of juveniles from the 1987-brood. In late July and early August 1988, 520 adult sockeye salmon were captured at fishway… more

A comparison of two- and three-dimensional S809 airfoil properties for rough and smooth HAWT (horizontal-axis wind turbine) rotor operation

Description: At the Solar Energy Research Institute (SERI), we carried out tests to measure the effects of leading-edge roughness on an S809 airfoil using a 10-m, three-bladed, horizontal-axis wind turbine (HAWT). The rotor employed a constant-chord (.457 m) blade geometry with zero twist. Blade structural loads were measured with strain gages mounted at 9 spanwise locations. Airfoil pressure measurements were taken at the 80% spanwise station using 32 pressure taps distributed around the airfoil surface. D… more

Confined Vortex Scrubber

Description: The program objective is to demonstrate efficient removal of fine particulates to sufficiently low levels to meet proposed small scale coal combustor emission standards. This is to be accomplished using a novel particulate removal device, the Confined Vortex Scrubber. This is the first quarterly technical progress report under this contract. Accordingly, a summary of the cleanup concept and the structure of the program is given here.

A continuous plasma final focus

Description: Scaling laws are set down for a plasma cell used for transport, focusing and current neutralization of fine, intense, relativistic electron beams. It is found that there exists a minimum beam spot size, {sigma}{sub min} {approximately} {epsilon}{sub n}(I{sub A}/{gamma}I){sup 1/2}, in such a focusing system. Propagation issues, including channel formation, synchrotron radiation, beam ionization and instabilities, are discussed. Three numerical examples are considered. 38 refs., 2 figs., 1 tab.

Control of alpha particle transport by spatially inhomogeneous ion cyclotron resonance heating

Description: Control of the radial alpha particle transport by using Ion Cyclotron Range of Frequency waves is investigated in a large-aspect-ratio tokamak geometry. It is shown that spatially inhomogeneous ICRF-wave energy with properly selected frequencies and wave numbers can induce fast convective transport of alpha particles at the speed of order {upsilon}{sub alpha} {approximately} (P{sub RF}/n{sub {alpha}}{epsilon}{sub 0}) {rho}{sub p}, where P{sub RF} is the ICRF-wave power density, n{sub {alpha}} i… more

Control of energetic ion confinement by ion cyclotron range of frequency waves

Description: It is shown that ICRF waves can induce fast convective radial transport of energetic ions in a tokamak geometry without affecting the background ion transport. Spatially inhomogeneous ICRF waves with directional parallel wave vectors are needed; otherwise, a net parallel flow of the energetic ions has to be present. 8 refs.
