An Investigation of the Relationships Between Counselors' Physiological and Therapeutic Responses in a Low-Stress and High-Stress Counseling Encounter

Description: The problem with which this study is concerned is to examine whether relationships can be identified between a counselor's change in verbal and physiological responses when subjected to low-stress and high-stress producing counseling encounters. It was concluded that under high-stress as opposed to low-stress conditions 1) counselors' heart-rates increase and become more variable; 2) counselors' levels of verbal effectiveness are relatively uninfluenced; and 3) no consistent and predictable relationship can be identified between counselors' verbal and physiological functioning. Caution is strongly advised in generalizing to subjects separate from this study.

Sacred Concert

Description: The composition is for large chorus, soloists and orchestra. It is in six movements and of about thirty minutes duration. The work is illustrative of texts from the Bible, " Pied Beauty by Gerard Manley Hopkins, and an early nineteenth century hymn by William More. The tonal resources used are based on diatonicism, altered and extended, with occasional use of the dodecaphonic technique as a device for melodic invention. The rhythmic resources are metered and unmetered. Traditional choral writing and devices of more recent origin are used in the composition of the vocal passages. The work is of moderate difficulty, and suggests departures from traditional choral concert programming. A commentary, instrument chart, and performance instructions precede the music. The commentary explains the general character of the work, the utilization of the text, and the techniques of composition. In addition, it presents a comparison of the movements.

Symphony Number Five

Description: Symphony Number Five is a composition in three movements for orchestra. It is characterized by an economy of materials and a clarity of presentation of those materials. Further, the materials are expressed in a simplistic manner which avoids intricate textural content and complex melodic and harmonic structures. The symphony was chosen as a pattern of structure for this composition since it represents a microcosm of the history and development of musical style since 1760.

The Effective Personal Integration Model and Its Impact Upon Locus of Control with Clients in Group Counseling

Description: The problem with which this investigation is concerned is that of the evaluation of the effectiveness of the EPIC model as a guide to group counseling. The purposes of this study are to determine (1) whether group counseling using the EPIC model would result in positive gain in counsele's locus of control, (2) whether there would be a differential effect of group counseling using the EPIC model as compared with a traditional group counseling model or a control group. This report concludes that the EPIC model as a guide to group counseling is an effective means of increasing reliance on inner support, emotional stability and objectivity. The EPIC model also produces changes in assessed congruence of the various factors in the actual vs. ideal aspect of inter-intrapersonal functioning. The EPIC model facilitated the growth of internal locus of control.

The Effects of the Note-Test System of Teaching General Microbiology on Student Achievement and Attitude

Description: The problem of this study was to compare the effectiveness of the note-test method and the traditional lecture method of teaching general introductory microbiology. The study was prompted by the desire to improve teaching strategies in microbiology in order to improve the attitudes of students taking microbiology at the Indiana College of Mortuary Science. The conclusions are that the note-test method of teaching is at least as effective as the traditional lecture method but is not better than the traditional method in regard to student achievement or student attitudes about the microbiology course to which they were assigned. Since the method requires less lecturing than the traditional lecture method used in this study, it may be used effectively by some instructors in certain subject matter areas and may hold promise in maintaining achievement and acceptable attitude levels.

Goal Identification and Systematic Instruction in Private Voice Lessons

Description: The problem of this study was to measure the effect upon the tone quality of singers resulting from identifying a specific goal, modeling with a cassette tape of the student's own voice, prescribing practice, and giving verbal approval. On the basis of the findings, these conclusions are drawn. (1) There is no significant difference in prescribing practice of an identified goal, utilizing a model or giving verbal approval. (2) Higher gain in pretest - posttest scores for the experimental groups while the control group showed the lowest gain suggests these teaching methods may be effective. (3) A high correlation of raters can be attained by the training method used in this study.

Low temperature heat capacity of lutetium and lutetium hydrogen alloys

Description: The heat capacity of high purity electrotransport refined lutetium was measured between 1 and 20/sup 0/K. Results for theta/sub D/ were in excellent agreement with theta values determined from elastic constant measurements. The heat capacity of a series of lutetium-hydrogen solid solution alloys was determined and results showed an increase in ..gamma.. from 8.2 to about 11.3 mJ/g-atom-K/sup 2/ for hydrogen content increasing from zero to about one atomic percent. Above one percent hydrogen ..gamma.. decreased with increasing hydrogen contents. The C/T data showed an increase with temperature decreasing below about 2.5/sup 0/K for samples with 0.1 to 1.5 atomic percent hydrogen. This accounts for a large amount of scatter in theta/sub D/ versus hydrogen content in this range. The heat capacity of a bulk sample of lutetium dihydride was measured between 1 and 20/sup 0/K and showed a large increase in theta/sub D/ and a large decrease in ..gamma.. compared to pure lutetium.

Synthesis and characterization of an N-(2-hydroxyethyl)-ethylenediaminetriacetic acid resin

Description: A chelating ion-exchange resin with N-(2-hydroxyethyl)ethylene-diaminetriacetic acid (HEDTA) used as the ligand chemically bonded to XAD-4 by an ester linkage, HEDTA-4, was synthesized. It is stable under normal experimental conditions with the liquid chromatograph. The structure of the resin was confirmed by an infrared spectrum, and by potentiometric titrations. The capacity of the resin was also obtained by potentiometric titration and by a nitrogen analysis. The resin was used to pack a column of 5 mm internal diameter and 5 cm long. The effect of pH on the retention of different metal ions on the resin was studied. It was found that the resin was most selective for chromium(III), copper(II), lead(II), mercury(II), uranium(VI), zirconium(IV) and zinc(II) at a pH of less than 3. Furthermore, the resin proves to be functioning with a chelating mechanism rather than ion-exchange, and it can concentrate trace metal ions in the presence of a large excess of calcium and magnesium. This makes the resin potentially useful for purifying and analyzing drinking water.

Electron microscopy of hydrocarbon production in parthenium argentatum (guayule)

Description: The electron microscope was used to study the biological processes involved in hydrocarbon production. The little desert shrub Guayule (Parthenium argentatum) was selected for study. This shrub can produce hydrocarbons (rubber) in concentrations up to 1/4 of its dry weight. It grows on semi-arid land and has been extensively studied. The potential of Guayule is described in detail. Results of an investigation into the morphology of Guayule at the electron microscope level are given. Experiments, which would allow the biosynthesis of hydrocarbon in Guayule to be followed, were designed. In order to do this, knowledge of the biochemistry of rubber formation was used to select a tracer, mevalonic acid. Mevalonic acid is the precursor of all the terpenoids, a large class of hydrocarbons which includes rubber. It was found that when high enough concentrations of mevalonic acid are administered to seedling Guayule plants, build-ups of metabolized products are found within the chloroplasts of the seedlings. Also, tritium labeled mevalonic acid was used as a precursor, and its metabolic progress was followed by using the technique of electron microscope autoradiography. The results of these experiments also implicated chloroplasts of the Guayule plant in hydrocarbon production. The final task was the development of a system to produce three-dimensional stereo reconstructions of organelles suspected of involvement in hydrocarbon biosynthesis in Guayule. The techniques are designed to reconstruct an object from serial sections of that object. The techniques use stereo imaging both to abstract information for computer processing, and also in the computer produced reconstruction.

Stress induced reorientation of vanadium hydride

Description: The critical stress for the reorientation of vanadium hydride was determined for the temperature range 180/sup 0/ to 280/sup 0/K using flat tensile samples containing 50 to 500 ppM hydrogen by weight. The critical stress was observed to vary from a half to a third of the macroscopic yield stress of pure vanadium over the temperature range. The vanadium hydride could not be stress induced to precipitate above its stress-free precipitation temperature by uniaxial tensile stresses or triaxial tensile stresses induced by a notch.

Electromigration of hydrogen and deuterium in vanadium, niobium, and tantalum

Description: The electric mobility and effective valence of hydrogen and deuterium in vanadium, niobium, tantalum and three niobium-tantalum alloys were measured. A resistance technique was used to directly determine the electric mobility of hydrogen and deuterium at 30/sup 0/C while a steady-state method was used to measure the effective valence. The use of mass spectrographic techniques on a single specimen which contained both hydrogen and deuterium greatly increased the precision with which the isotope effect in the effective valence could be measured.

Use of a semiconductor laser in infrared spectroscopy

Description: A semiconductor laser has certain properties which makes its use desirable as a continuous monitor of atmospheric pollutants. Its energy output is concentrated in widely separated energy modes of very narrow bandwidths (less than 10/sup -5/ cm/sup -1/) which can be centered on one infrared absorption line of one gas. This makes the laser quite selective. The energy in each mode is typically greater than 200 ..mu.. watts, and, because of the laser's small size, its light energy can be collimated over large distances with minimal optical losses and be easily detected. One can rapidly measure the decrease in transmission of the light due to the absorption of the light by the gas being monitored, and, using certain analytical parameters, which are different for each absorption line, one can determine the concentration of the gas in question immediately. In addition to the line center (nu/sub 0/), these analytical parameters are the intensity (S) and the half width at half maximum (..gamma..). The intensity (S) is dependent only on temperature when expressed in a per concentration basis and ..gamma.. is dependent on pressure. The Lorentzian lineshape equation K(nu) + S/..pi gamma..(((nu - nu/sub 0/)/..gamma..)/sup 2/ + 1)/sup -1/ is the equation which describes the absorption profile of a gas at ambient atmospheric pressure. Having determined K(nu) and knowing atmospheric pressure and path length of the laser light, one can obtain the concentration of the gas in question. Infrared absorption lines of N/sub 2/O, SO/sub 2/, and H/sub 2/S are observed from low pressure (equal or approximately equal 0.1 torr) to a total pressure of one atmosphere when mixed with room air. The analytical parameters S and ..gamma.. are determined for some lines of N/sub 2/O, and nu/sub 0/, S, and ..gamma.. are determined for several absorption lines of SO/sub 2/. Also …

Inductively coupled plasma--atomic emission spectrometry: trace elements in oil matrices

Description: The simultaneous determination of up to 20 trace elements in various oil matrices by inductively coupled plasma-atomic emission spectrometry is reported. The oil matrices investigated were lubricating oils (for wear metals), fuel oil, centrifuged coal liquefaction product, crude soybean oil, and commercial edible oils. The samples were diluted with appropriate organic solvents and injected into the plasma as an aerosol generated by a pneumatic nebulization technique. Detection limits of the 28 elements studied ranged from 0.0006 to 9 ..mu..g/g with the majority falling in the 0.01 to 0.1 ..mu..g/g range. Analytical calibration curves were linear over at least two orders of magnitude and for some elements this linearity extended over 4.5 orders of magnitude. Relevant data on precision and accuracy are included. Because metals often occur as particles in lubricating oil and coal liquefaction products, the effect of particles on the analytical results was examined. Wear metal particles in used oil did not appear to affect the analytical results. However, incomplete recovery relative to organometallic reference solutions was obtained for iron particles with a nominal mean diameter of 3.0 ..mu..m suspended in oil. It was shown that the following factors contributed to incomplete recovery for the particles: settling of the suspended particles in the flask, a difference in nebulization efficiency between particle suspensions and organometallic solutions, and indications of incomplete vaporization of the larger particles in the plasma.

Lanthanide extraction with 2,5-dimethyl-2-hydroxyhexanoic acid

Description: This research is concerned with the solvent extraction into chloroform of the lanthanides, using 2,5-dimethyl-2-hydroxyhexanoic acid (DMHHA). This acid is the first ..cap alpha..-hydroxy aliphatic acid to be studied as an extracting agent for the lanthanides. The chloroform-water DMHHA partition constant was determined to be 1.0 (at 0.1 M ionic strength and 25/sup 0/C). The acid dimerizes in chloroform with a constant of 56. The light lanthanides can be extracted into chloroform by forming complexes with the DMHHA anions. The extracted metal species is highly aggregated. This extraction has a solubility limit which increases with the addition of unionized acid. The resultant extract is also highly aggregated. At unionized acid-to-metal ratios greater than one, extractions first occur followed by the slow precipitation of the lanthanide. At the tracer level, neodymium is extracted primarily as NdA/sub 3/(HA)/sub 5/ and (NdA/sub 3/)/sub 2/(HA)/sub q/. Very small amounts of (NdA/sub 3/)/sub 2/ and other metal aggregates are also present. The heavy lanthanides do not extract from solutions of DMHHA and its potassium salt, but form aqueous emulsions and precipitates. In the presence of the organic soluble tetrabutylammonium ion the heavy lanthanides can be extracted, presumably as ion pairs. The stability constants of the light lanthanides and DMHHA were determined. The separation factors obtained from DMHHA extractions of the light lanthanides were also investigated and found to be comparable to those obtained employing normal aliphatic carboxylic acid.

Investigation of high energy runaway electron confinement in the Oak Ridge tokamak

Description: High energy runaway electrons in the Oak Ridge tokamak ORMAK have been investigated through measurement of the bremsstrahlung produced when these electrons leave the discharge and strike the limiting aperture of the torus. The experimental results have been interpreted in terms of a classical single-particle model appropriate for collisionless particles in a tokamak, and it has been found that most of the confinement properties of high energy runaways in ORMAK can be understood on this basis. An experiment designed to directly test this model has disclosed an anomalous transport which has been described by a runaway diffusion coefficient D approximately 10/sup 2/ to 10/sup 4/ cm/sup 2//sec appropriate for runaways near the outside of the plasma. A discussion of the possible mechanisms for this anomalous transport is given.

Heated uranium tetrafluoride target system to release non-rare gas fission products for the TRISTAN isotope separator. [As replacement for uranyl stearate]

Description: Off-line experiments indicated that fluorides of As, Se, Br, Kr, Zr, Nb, Mo, Tc, Ru, Sb, Te, I and Xe could be volatilized, but except for Br, Kr, I and Xe, none of these elements were observed after mass separation in the on-line experiments. The results of the on-line experiments indicated a very low level of hydride contamination at ambient temperature and consequently, uranium tetrafluoride replaced uranyl stearate as the primary gaseous fission product target. Possible reasons for the failure of the heated target system to yield non-rare gas activities are discussed and suggestions for designing a new heated target system are presented.

Evaluation of self-interaction parameters from binary phase diagrams

Description: The feasibility of calculating Wagner self-interaction parameters from binary phase diagrams was examined. The self-interaction parameters of 22 non-ferrous liquid solutions were calculated utilizing an equation based on the equality of the chemical potentials of a component in two equilibrium phases. Utilization of the equation requires the evaluation of the first and second derivatives of various liquidus and solidus data at infinite dilution of the solute component. Several numerical methods for evaluating the derivatives of tabular data were examined. A method involving power series curve fitting and subsequent differentiation of the power series was found to be the most suitable for the interaction parameter calculations. Comparison of the calculated self-interaction parameters with values obtained from thermodynamic measurements indicates that the Wagner self-interaction parameter can be successfully calculated from binary phase diagrams.
