Fundamental theory of elastic wave scattering by defects in elastic materials: integral equation methods for application to ultrasonic flaw detection

Description: The use of ultrasonic methods in nondestructive testing depends on the interpretation of the scattering of sound waves by flaws. The theory of elastic waves and their scattering in non-uniform media is developed in detail from first principles, and in generality. Both integral equation and differential methods are discussed, with emphasis on the former. General methods for defining scattering cross sections are presented, and conservation theorems are noted. The Born Approximation to the integr… more

Predicted Heat-Transfer Performance of an Evacuated Glass-Jacketed CPC Receiver : Countercurrent Flow Design

Description: The heat-transfer performance of an evacuated glass-jacketed CPC-receiver facility, free on one end and fixed onto the glass jacket at the other, was carried out using heat-transfer relationships and the best information available in the literature. Specifically, the collector examined was a 3x-CPC facility, 8 ft long, with an entrance aperture 4.5 in. wide covered with a single glass cover, and provided with an aluminum reflecting surface (rho = 0.88). To maximize heat retention, a selectively… more

The Atomic Spectrum of Neptunium

Description: A description and interpretation of the atomic spectrum of neptunium are given. Wavelengths were measured for 6096 spectrum lines in the range 3793 to 38,812 cm⁻¹ (26,353 to 2575 A), of which 2526 were classified as transitions between 329 odd levels and 130 even levels of neutral neptunium (Np I). The data are presented in five tables.

Application of Frequency-Modified Life Approach to the Low-Cycle Fatigue Behavior of Type 304 Stainless Steel

Description: The application of the frequency-modified life equation to fatigue life prediction has been critically examined using the extensive fatigue data generated for Type 304 stainless steel at 1100 degrees F under a variety of cyclic-loading conditions. The parameters that enter into the frequency-modified life equation vary with strain rate and show a transition coinciding with the frequency of cycling at which a change in the fracture appearance from predominantly transgranular to predominantly int… more

Use of Krypton-85 for the Detection of Pinhole Failures in GCFR Cladding

Description: Radioactive krypton-85 is used as a tracer to detect pinhole failures in GCFR cladding. High-purity helium (99.99% pure) that contains 0.3 ppm krypton-85 is used to pressurize the tubular test specimens, and a Geiger-Mueller counter is used to detect the krypton-85 in the helium environmental gas as it leaves the test chamber. Under the least favorable conditions of temperature and specimen pressure, it is estimated that the smallest pinhole failure that could be detected within 60 sec would ha… more

Baseline Energy Consumption Forecasts for Transportation: A Review and Evaluation

Description: A baseline projection of energy consumption is needed to estimate the potential energy savings from proposed transport technology and operational improvements. The Reference Energy System projection by Brookhaven National Laboratories and that which Stanford Research Institute produced for Gulf Oil are reviewed here. Attention is focused on the growth rate assumptions of the forecasts and the allowances made for the sensitivity of transport demand and technological efficiency to fuel price chan… more

Development of a prototype high temperature amplifier for geothermal well logging. Final report

Description: A high temperature amplifier for use in geothermal well logging was developed. This development was based on the use of ceramic vacuum tubes as the active circuit element, since these tubes have the capability to operate in the high ambient temperature environment. The primary goal of this program was to design, build, and deliver a prototype amplifier capable of continuous operation in a 250/sup 0/C environment. A development program designed to meet this goal covered four phases. These phases… more

A study of the effects of personality, subculture and place of residence on college student recreation participation

Description: The problem of this investigation was to determine whether knowledge of student personality, subculture, or place of residence could predict university student recreation participation for men and women. Factors of age, marital status, class in college, and Greek affiliation were also examined for any relationship to recreation participation of university men and women.

Factors affecting the activity of cyclopropane synthetase in Lactobacillus plantarum

Description: This investigation concerned determining certain factors which affect the activity of cyclopropane synthetase in L. plantarum. In vitro experiments showed the enzme to be sensitive to ionic strength and subject to product inhibition by S-adenosylhomocysteine nucleusidase, which relieves this inhibition by degrading SAH to adenine and ribosylhomocysteine.
