0. 20-m (8-in.) Primary Burner Development Report
High-Temperature Gas-Cooled Reactors (HTGRs) utilize graphite-base fuels. Fluidized-bed burners are being employed successfully in the experimental reprocessing of these fuels. The primary fluidized-bed burner is a unit operation in the reprocessing flowsheet in which the graphite moderator is removed. A detailed description of the development status of the 0.20-m (8-in.) diameter primary fluidized-bed burner as of July 1, 1977 is presented. Experimental work to date performed in 0.10; 0.20; and 0.40-m (4, 8, and 16 in.) diameter primary burners has demonstrated the feasibility of the primary burning process and, at the same time, has defined more clearly the areas in which additional experimental work is required. The design and recent operating history of the 0.20-m-diameter burner are discussed, with emphasis placed upon the evolution of the current design and operating philosophy.

40 kW of solar cell modules for the Large Scale Production Task, a Low Cost Silicon Solar Array Project. Final technical report
Forty kilowatts of solar cell modules was produced in this program. This is equivalent to 4123 modules. The average power output per module was 9.7 watts at 16.5 volts, 60/sup 0/C and 100 mW/cm/sup 2/. The peak production rate was 200 modules per week which is equal to 1.9 kW per week. This rate was sustained for over four and one-half months and is equivalent to 100 kW per year. The solar cell module design, electrical and power performance, module preproduction environmental test results, production and shipping schedule, program summary, and delivery are described. A cost analysis section is written. Particular emphasis on the percentage of labor and material utilized in constructing a solar cell module is presented. Also included are cost reduction recommendations. It was concluded from this program that volume production on the order of hundreds of kilowatts per year per company as a minimum is required to significantly reduce the price per watt for solar cell modules. Sensor Technology more than doubled its solar cell module manufacturing facilities since the completion of the JPL Block II procurement. Plans are being made for large scale expansion of our facilities to meet growing JPL/DOE procurements.

1977 breeding bird censuses and vegetation surveys in two successional stages of oak--pine forest
As part of a program to characterize the plant and animal life of the Laboratory site and surrounding areas, two breeding bird census plots were established in 1977 to document the occurrence and abundance of breeding species in two extreme successional stages of Long Island oak-pine forest. A 9.3-hectare plot located near the northeastern corner of the Laboratory site is composed of second growth oak-pine forest in a late successional stage. The second plot measures 9.7 hectares and is located in the scrub oak-pitch pine barrens at Westhampton. Each plot was surveyed with a transit and steel tape and marked with wooden stakes at 100-foot intervals. Quantitative vegetational surveys were made in each plot and all plant species identified. Tree composition was measured as a function of species and size. Shrub density, percent of ground cover and percent of canopy were also measured. The Laboratory plot contained 2100 trees of five species per hectare, 72% ground cover and 84% canopy coverage. The Westhampton plot contained only one tree species, Pitch Pine, at 366 trees per hectare, 92% ground cover and no canopy. Twelve census trips, mostly of two to three hour duration, were made in each plot. Each bird observed …

Acid rain research program. Annual progress report, July 1976--September 1977. [Effects on plants and soil microbiological processes]
Experiments were carried out and chemical aspects of ambient precipitation were determined using a sequential precipitation collector for the period July 1976 through September 1977. A related report provides experimental details. In experiments with plants, experiments were aimed to document: the foliar response of six clones of hybrid poplar to simulated acid rain; effects of buffered solutions and various anions on vegetative and sexual development of gametophytes of the fern (Pteridium aquilinum) and the acid-sensitive steps of symbiotic nitrogen fixation of the garden pea (Pisum sativum). After five 6 min daily exposures to simulated rain of pH 2.7, up to 10 percent of the leaf area of some poplar clones was injured. Lesions developed mostly near stomata and vascular tissue as shown with other plant species. Acidic solutions have a marked effect on sperm motility and fertilization (sexual reproduction) of bracken fern. Since sexual reproduction of ferns is very sensitive to mildly acidic conditions under laboratory conditions, experiments are planned to view the response of sexual stages of other plant species. Nodulation and symbiotic nitrogen fixation in Pisum is very sensitive to nutrient solution acidity. Specific isolates of Rhizobium bacteria are used and the medium pH can be maintained rigidly. …

An Acoustical Study of Individual Voices in Choral Blend
The purpose of this study was to investigate the phenomenon of choral blend through acoustical analysis of individual vocal sounds. One aspect of the study involved identifying and comparing the acoustical qualities of sounds produced in the usual solo manner and sounds produced by the same singers attempting to blend with a unison ensemble. Another aspect of the study involved identifying and comparing the acoustical qualities of vocal sounds identified as blending well and poorly with a unison ensemble. Singers attempting to blend adjust their overall intensity not only to affect the perceived loudness of their tones, but also to facilitate other acoustical changes which are helpful for achieving blend. Vocal blend apparently may be achieved more readily on vowels having few upper partials than on vowels having numerous upper partials. Where vibrato is employed, certain vocal sounds can achieve a good blend even though their fundamental frequencies only approximate the theoretically correct frequency. There apparently is an interaction between the vibrato of a vocal tone and its spectral features, making it advantageous for the singer to adopt mutually beneficial approaches to both factors in order to blend. Vowel modification effective for achieving vocal blend- -at least for sopranos-- appears …

Aerodynamic particle size measurement by laser--Doppler velocimetry. Publication number 343
A method of measuring the aerodynamic diameter of aerosol particles was investigated. The method consists of accelerating particles in a coverging nozzle and measuring their velocities near the exit of th nozzle with a laser--Doppler velocimeter. The experimental studies utilized a test nozzle with a converging angle of approximately 15/sup 0/ and an exit diameter of about .1 cm. The pressure drop across the nozzle was varied from 2.54 to 276 cm of H/sub 2/O, and particle velocity was observed to vary from approximately 0.5 to 1.0 times the gas velocity at the exit of the nozzle. A theoretical analysis utilized boundary layer theory to predict the velocity of the gas in the nozzle, and then the equations of particle motion were integrated to give the theoretical particle velocities. These values agreed with the experimental values to within a few percent. The effects of nozzle geometry, flow rate, particle density, and particle size were studied using the results of calculations made with dimensionless equations. The velocity of a particle in a given nozzle and flow depends upon the aerodynamic diameter of the particle and the particle density. The geometry and flow can be chosen to minimize the effect of particle …

Aluminum Alloy Performance Under Dry Cooling Tower Conditions
The performance of aluminum alloys as fin material in dry cooling towers is evaluated from data on dry-cooled equipment in Europe and the US and laboratory tests which simulated dry cooling tower conditions. This study concluded that: aluminum alloys can be expected to have lifetimes of 30 years or more at dry cooling tower temperatures in ''clean'' environments; chloride is clearly an aggressive agent on aluminum components; corrosion is most severe at temperatures below the dew point, where moisture can participate in the attack; severe corrosion seldom occurs at dry cooling tower temperatures, unless the plant is subject to considerable downtime; caked coal dust promotes aluminum corrosion, and therefore, the relative siting of the cooling tower and the coal pile is an important consideration; and laboratory studies at dry cooling tower and ambient temperatures caused corrosion similar to corrosion on some plant specimens.

American Arms Sales to Iran and Power Politics in the Middle East
This thesis examines and evaluates the questions involved in American arms sales to Iran and Egypt. The first two chapters outline the historical background and present detailed analyses of Iran's political situations prior to 1968 and United States policy toward it in that period of time. Chapter Three considers the American policies towards Egypt and the United States arms sales to that country. The main argument of the thesis appears in chapter Four which explains the objectives of Iran's government in buying American arms and the United States government's objectives in selling arms to Iran. Conclusions on the study comprise the fifth chapter.

American Response to Military Coups among Her Allies: Greece--The Colonels' Coup
The focus of this thesis is Greece after the 1967 Colonels' Coup. After an analysis of American responses to military coups among allies since 1949, the Greek situation is explored in depth. Emphasis is given to Congressional and Executive infighting and bureaucratic interpretations of policy. The two presidents who dealt with the Colonels are studied for personal reaction. Sources include the New York Times and its Index, the Department of State Bulletins, current Greek history books, Congressional Hearings and other documents relating to Greece. Major conclusions are that Congressional- Executive infighting produced a meandering non-policy toward Greece, and there was a difference in Johnson's and Nixon's reaction with the latter being more pragmatic verbally but less effective factually.

Analytical applications of resins containing amide and polyamine functional groups
A dibutyl amide resin is used for the separation of uranium(VI), thorium(IV), and zirconium(IV) from each other and several other metal ions. Uranium(VI) and thorium(IV) are determined in the presence of large excesses of foreign metal ions and anions. A practical application of the amide resin is studied by determining uranium in low grade uranium ores. The amide resin is also used for the selective concentration of gold(III) from sea water.
