Genetic effects of low x-ray doses. Progress report, October 1, 1976--September 30, 1977. [In Drosophila]
A linear-quadratic model of dose-kinetics is proposed for x-ray induced recessive lethal mutations in oogonia of Drosophila. From this it should follow that at higher total doses fractionation treatments should give a lower yield of mutations than an equivalent acute exposure. A dose of 6000 R, given acutely and in 3 different fractionation regimes gave results in the expected direction for 2 x 3000 R, and a significant decrease for 3 x 2000 R and for 4 x 1500 R fractionations.

Energy calibration scheme for acoustic emission
The calibration technique described is an attempt to determine the actual energy release from the events causing emission bursts in beryllium and to quantitatively evaluate the effects of specimen geometry on the apparent energy per burst. (GHT)

A Field Test of Selected Insects and Pathogens for Control of Waterhyacinths, Report 1: Preliminary Results for the 1975-76 Season
"During the growing season of 1975, a field experiment was initiated on Lake Concordia, Louisiana, to test the potential effectiveness of selected organisms as control agents against waterhyacinths, Eichhornia crassipes (Mart.) Solms. [...] This report describes the experiment, presents the collected data, and summarizes the observations. Statistical analyses and interpretation of the data are also presented" (abstract).

Hydrogen-engine performance-analysis project. Third quarterly report first year of program
The objective of this research effort is to obtain the design data-base covering performance, operational characteristics and emissions essential for making a rational decision regarding the selection and design of prototype hydrogen-fueled, air-breathing engines capable of being manufactured for general automotive use. To this end hydrogen-fueled internal combustion engines were divided into fourteen subgroups. An engine representative of each subgroup will be tested during the course of the three year program. The Project Program Plan calls for investigation of pre-intake valve closing fuel ingestion (Pre IVC) hydrogen-fueled engines during the first two years. Work accomplished during the third 3-month period of the project is reported. Activities in this quarter included: water injection experiments with the throttled and unthrottled engine mode of operation; design and construction of exhaust gas recirculation (EGR) equipment for use with the EGR experiments with the throttled and unthrottled engine configuration; construction of lithium-filled exhaust valves; and analysis of data for annual report preparation purposes.

DAMAGE TO MITOCHONDRIAL ELECTRON TRANSPORT AND ENERGY COUPLING BY VISIBLE LIGHT
Plutonium is one of the principal materials of both commercial and military nuclear power. It is produced primarily in fission reactors that contain uranium fuel, and its importance arises from the fact that a large portion of the plutonium produced is fissile: like uranium 235, the mass 239 and 241 isotopes of plutonium can be caused to fission by neutrons, including those with low energy. Because such fission events also release neutrons, substantial amounts of energy can be extracted from plutonium in a controlled or an explosive nuclear chain reaction. Now that commercial nuclear reactors provide a noticeable fraction of United States (and world) electrical energy, these reactors account for most plutonium production. For the most part, this material now remains in the irradiated fuel after removal from reactors, but should this fuel be reprocessed, the plutonium could be recycled to provide part and even most of the fissile content of fresh fuel. For the current generation of water-cooled reactors, the amount of plutonium to be recycled is substantial. In fast breeder reactors, designed to produce more fissile material than they destroy, considerably larger quantities of plutonium would be recycled. In other types of advanced reactors, particularly those which depend …
