Linear compartment model of plutonium dynamics in a deciduous forest ecosystem
Systems ecology techniques have been useful in simulating the fate and dynamics of radionuclides in forest ecosystems. The applications of systems models in this context are twofold: projection of the time-dependent distribution of radioisotopes among various ecosystems components, and manipulation of the modeled system to determine the sensitivity of components to variation in transfer coefficients and, thereby, identify critical fluxes affecting system behavior. The present paper describes a systems model that projects the possible fate of plutonium in a deciduous forest ecosystem. The isotopes of interest are /sup 239/Pu and /sup 240/Pu which have physical half lives of 2.44 x 10/sup 4/ and 6540 years, respectively. These isotopes are indistinguishable by alpha spectrometry hence /sup 239/Pu is used to refer to both.

Simulation in the service of environmental research: experience with a stream ecosystem project
A perspective on the use of simulation modeling as one working component of a complex ecosystem research project is presented. Experiences with modeling in the context of a research program dealing with nutrient dynamics in stream ecosystems are documented. As the project progressed, the role of modeling changed, resulting in four distinct models, each developed for a specific purpose. The models have been used to screen initial hypotheses, set up details of the experimental design, analyze results, and serve as a logical framework for investigating mechanistic details of the ecosystem. Through time, individual models were discarded, not because they were inadequate, but because they were irrelevant to the next stage of the project. It was particularly interesting to note how the importance of validation, as well as its characteristics, have changed during this process.

Study of efficient high-power, high-energy neutral beams for the Reference Mirror Reactor
An injector design for the Reference Mirror Reactor is described which uses negative ions created by charge-exchange in a cesium vapor cell and neutralized by photodetachment. Some of the innovations discussed include a continuously operating cathode for an LBL/LLL ion source, a negative ion beam line with cooled grids, a high voltage accelerator configuration with insulators shielded from the neutron and gamma flux, and cryopanels which continuously cycle between pumping and outgassing modes.

Geothermal observation wells, Mt. Hood, Oregon. Final report, October 4, 1977-July 9, 1979
Exploration drilling operations were conducted which included the deepening of an existing hole, designated as Old Maid Flat No. 1, from 1850 ft (564 m) to 4002 (1220 m) on the western approaches to Mt. Hood and the drilling of three new holes ranging from 940 ft (287 m) to 1340 ft (409 m). The Clear Fork hole, located in Old Maid Flat, was drilled to 1320 ft (402 m). The Zigzag hole was drilled to 940 ft (287 m) at the southwestern base of Mt. Hood in the Zigzag River valley. The remaining hole was drilled on the Timberline Lodge grounds which is on the south flank of Mt. Hood at an elevation of about 6000 ft (1829 m) above sea level. The deepening project designated as Old Maid Flat No. 1 encountered a maximum bottom hole temperature of about 180/sup 0/F (82/sup 0/C) and is to this date the deepest exploratory hole in the Mt. Hood vicinity. No significant drilling problems were encountered. The Clear Fork and Zigzag River holes were completed without significant problems. The Timberline Lodge hole encountered severe drilling conditions, including unconsolidated formations. Two strings of tools were left in the hole from structural collapse …

Land and water resources for environmental research on Oak Ridge Reservation
Resources for environmental research on the Oak Ridge Reservation are analogous to the highly complex, physical and engineering facilities of the Oak Ridge National Laboratory. Consequently, land and water resources have been committed to comprehensive research for the purpose of providing relevant, scientific insights on environmental problems associated with ERDA's programs. Diverse aquatic, terrestrial, and agricultural ecosystems are designated for short- and long-term research related to environmental impacts or benefits of different energy technologies. Examples of ecosystems employed in this research include hardwood and pine forests, grasslands and pastures, free-flowing streams and impounded reservoirs, field plots, contaminated environmental natural areas, an array of animal habitats, and calibrated watersheds. Some of the characteristic biota of habitat ecosystems are described in the document. Documentation and planning for use of these lands, waters, and biotic resources also respond to the broad issue of appropriate usage of Federal lands.

Development of the ion source for PDX neutral beam injection
The paper describes the development of the ion source for neutral beam injection heating of PDX plasma. After a brief description of the plasma generator, the performance characteristics of the source, with different types of grids, are described. Based on test stand results it is concluded that at least two different versions of the source should be able to meet and even exceed the neutral power and energy requirements expected out of PDX injectors.

Electron Transfer Experiments and Atomic Magnetism Values. Progress Report, February 1, 1975--September 30, 1975
Progress in the first seven months of this new research is described. A new apparatus was constructed, tested and moved to Oak Ridge National Laboratory for studies using the Penning ion source test facility. Preliminary electron transfer cross section results for N$sup 4+$, N$sup 5+$, He$sup 2+$ and C$sup 5+$ ions on gases were obtained. Energy loss measurements made to date support expectations that single electron transfer for multiply-charged ions colliding with gas atoms produces excited final state ions. (auth)

Cross section measurement for the /sup 52/Cr(n,p)/sup 52/V reaction near threshold
Cross sections for this reaction were determined in the range 5.3 to 9 MeV using a previously-reported pulsed-accelerator technique to measure gamma ray activity from 3.75 m /sup 52/V. Very few experimental data have been reported for this reaction, and little was known about the threshold region prior to the present experiment. The results of this work (in conjunction with other available cross section information) were used in the computation of fission-spectrum averages which are of interest for reactor applications.

Analysis of (n,2n) cross-section measurements for nuclei up to mass 238
All suitable measurements of the energy dependence of (n,2n) cross sections of all isotopes up to mass 238 have been analyzed. The objectives were to display the quality of the measured data for each isotope and to examine the systematic dependence of the (n,2n) cross section upon N, Z, and A. Graphs and tables are presented of the ratio of the asymptotic (n,2n) and nonelastic cross section to the neutron-asymmetry parameter (N--Z)/A. Similar data are presented for the derived nuclear temperature, T, and level-density parameter, $alpha$, as a function of N, Z, and A. This analysis of the results of over 145 experiments on 61 isotopes is essentially a complete review of the current status of (n,2n) cross-section measurements. (auth)

Levels of chemical contaminants in nonoccupationally exposed U. S. residents
Data are presented on the levels of all chemical contaminants resulting from environmental pollution which have been found in human tissues including blood, urine, breast milk, and tissue samples obtained at autopsy. Most data results from specific surveys to determine health hazards. The roles of trace elements and recognition of the need to determine baseline levels of chemicals introduced into the environment are factors which have motivated surveys by individual investigators. Thus, most data on chemicals in human tissues record levels of pesticides (e.g., DDT and metabolites), levels of trace metals such as lead, cadmium, and mercury, or levels of nutritionally essential elements such as zinc, copper, manganese, and fluoride. Data available on iron and calcium are not presented as their presence in the environment is generally not considered hazardous. Data on several uncommon chemicals, such as indium and ytterbium, are included basically as items of interest and to further document their presence in healthy individuals. Baseline data were presented where available to provide perspective as to chemical levels which might be expected under conditions where exposure could be considered normal or not directly related to a pollutant source. Nearly 600 cited surveys or investigations, most of which were reported …

The Trombone in German and Austrian Concerted Church Music of the Baroque Period: A Lecture Recital, Together with Three Recitals of Selected Works of L. Basset, L. Grondahl, W. Hartley, V. Persichetti, K. Serocki, H. Tomasi, D. White and Others
The dissertation consists of four recitals: three solo recitals and one lecture recital. The repertoire of all the programs was intended to demonstrate a variety of music written originally for trombone. The lecture recital, "The Trombone in German and Austrian Concerted Church Music of the Baroque Period," was presented on July 3, 1974. The lecture was an attempt to illuminate the position of the trombone, both as an ensemble instrument and as a solo obbligato instrument, in church music of the Baroque period. The program included the performance of two works by Heinrich Schutz for bass voice, four trombones, and continuo; one work by Andreas Hammerschmidt for alto, bass, trombone, and continuo; and one work by Johann Joseph Fux for soprano, trombone, two violins, and continuo. A line of influence was traced from the Venetian composers Giovanni Gabrieli and Claudio Monteverdi, through Schiitz, Hammerschmidt, and Fux, to Mozart.
