Kinetic studies of the cobalt (II)-4, 4’, 4’’, 4’’’-tetrasulfophtalocyanine and cyanide system were performed under argon and in air over temperature ranges of 294-314°K and 294-324°K, respectively. Two reactions were detected under argon. One was quite rapid and was followed on the stopped-flow apparatus. The results are consistent with the perturbation of a monomer-dimer equilibrium. The second reaction was slow enough to be followed spectrophotometrically on the Cary Model 14 spectrophotometer. The second order rate constant of 0.11 M-1 sec-1 at 294°K has been attributed to the rate of substitution of the second cyanide addition to a dye-cyanide complex. Activation parameters, ΔH* and ΔS* were obtained over a temperature range of 294-314°K yielding values of 3 +/- 0.3 kcal/mol and -56 +/- 5 e.u., respectively. Reexamination of this system in air revealed three reactions. The first reaction was rapid and measurable on the stopped-flow apparatus. This reaction has been interpreted as a perturbation of the monomer-dimer equilibrium. The other reactions were monitored o the Cary Model 14 spectrophotometer and produced a biphasic curve. The slower reaction yields a rate constant, ks of 3.4 +/- 0.15 x 10-3 s-1 at 294°K and is in agreement with the value reported for the dissociation of the dimer when corrections are made for differences in ionic strength. The activation parameters ΔH* and ΔS* for the slow step were calculated to be 9.1 +/- 0.9 kcal/mole and -39 +/- 3 e.u., respectively, over a temperature range of 294-324K. We have no good explanation for the faster step, kf. However, a linear plot of 1n (dye concentration) vs. time shows kf is a first order rate constant with a value of 2.0 +/- 0.15 x 0.10-2 s-1 at 294°K. There was no dependency of kf on oxygen concentration, thus oxidation involving molecular oxygen is excluded as a possible step Moreover, there is no simple relationship between kf and cyanide concentration. Activation parameters, ΔH*f and ΔS*f of 7.6 +/- 0.5 kcal/mole and -40 +/-4 e.u., respectively, were obtained over a temperature range of 294-324°K.

The object of this investigation was to study the homogeneously catalyzed reaction of acetylene and ammonia and particularly to attempt to synthesize ethylamine by the reaction of acetylene and ammonia.

This research examined the problem of professional obsolescence and mechanisms available to employees to avoid becoming obsolete. Current literature is reviewed on obsolescence and on remaining current in the nursing profession. Specific areas addressed are indicators of obsolescence and an examination of what happens to skills and abilities when an individual moves from a technical field into its administration. Participants in the research include registered nurses at three hospitals. The research is composed of two phases: an interview phase and a survey phase. Qualitative and quantitative analysis reveal categories of concerns about remaining current. The special concerns an obsolescence of administrative nurses is also addressed.

The study reported examined the relationship between self-actualization and aspects of female sexuality. Ninety-five white, single female undergraduates from a regional Southeastern state university volunteered to serve as subjects. Three questionnaires were administered to the subjects: the Personal Orientation Inventory (POI), Eysenck’s Inventory of Attitudes to Sex, and a two-item religiosity measure. The data were analyzed via correlation and hierarchical multiple regression analysis. The results indicated that when the effects of the covariates were controlled, there was a significant relationship between self-actualization and sexual permissiveness, sexual satisfaction and prudishness. Although self-actualization and sexual libido were significantly correlated, after the effects of the covariates were controlled, self-actualization did not account for a significant portion of the variance in sexual libido. The importance of controlling for extraneous variables when examining the relationship between self-actualization and sexual attitudes is stressed. Implications for future research include using different populations to investigate the relationship between self-actualization and sexual attitudes, using different measures of self-actualization to investigate its relationship to sexual attitudes, and examining the relationship between self-actualization and other aspects of sexuality.

Cold vapor flameless atomic absorption spectrophotometry is an analytical method used in the determination of mercury. Its sensitivity is less than one part per billion using a 100 milliliter sample, and there are virtually no interferences from other metal ions. The method is best carried out making use of a permanganate-persulfate oxidation step with heat. The ylide, triphenylphosphoniumcyclopentadienylide (CpPPh3), which extracts mercury almost quantitatively from water, was used in attempts to remove mercury from exposed goldfish. Though not toxic to the fish, CpPPh3 did not significantly lower mercury levels. Evaluation of CpPPh3 as a possible phase transfer catalyst failed to identify a true catalytic species.

In Rough River Lake, Kentucky, some aspects of the ecology of larval and juvenile fishes were investigated from April – August, 1978. Larval fishes were collected weekly from the upper reaches of the lake from the surface and bottom, during daylight and dark periods. Twenty-three species and three categories of unknown larval and juvenile fishes, represented by 177,119 individuals, were collected. White bass and logperch larvae were the first to appear on April 15 with surface water temperatures of 18.5 C. Gizzard shad larvae dominated net collection while Lepomis spp. were the second most abundant. Larvae were primarily concentrated near the surface and taken mostly at night. Larval concentrations were greatest on May 30. Throughout the study, most specimens were collected along the shorelines. Growth rates of most taxa generally lagged early in life but increased greatly after the first 6-8 weeks. Light traps proved to be an effective method of capture for certain species. Piscivory was observed in white bass 10.5 – 25 mm total length on gizzard shad, and logperch 16.5 – 17 mm total length on unknown larvae and suckers.

Traditional sociological conceptions of professions are examined in this thesis by refocusing attention upon knowledge and ideology as a key to understanding changes in professional reality and action. In a proposed transcending model of professional knowledge it is hypothesized that conflicts between certain ideological positions will result in the displacement of one position by an opposing position and thereby produce changes in the definition and meaning of specific aspects of professional knowledge. Furthermore, it is suggested that knowledge construction, ideological debate, and changes in professional meaning may be observed in the arena of professional communication which is represented by major professional journals in a field. Using the field of social work as a test case for this study, a content analysis design is employed to examine population of 778 journal articles appearing in this field’s major journal publication, Social Work, from 1956 through 1973. The results of this analysis indicate the presence of six identifiable ideological positions in social work knowledge. Three pairs of these ideological positions were found to conflict and vary inversely with each other between 1956 and 1974, and thereby illustrate three unique temporal patterns of ideological conflict and debate. Another set of ideological positions were found to be positively associated together and vary inversely with an opposing constellation of ideological claims. In general, these findings support the proposed transcending model and evidence a relatively radical change in the defined meaning of social work from 1956 through 1973. Several possible interpretations of these findings are explored from the perspective of traditional sociological conceptions of professions and the proposed transcending model. The favored interpretation suggests that the normative view of the professions is outdated by recent changes in professional meaning, and that a processual conception of the professions and their operation as dynamic and competitive is a more accurate and useful theoretical model of professions, their reality, and their change. Implication of the results of this study for social service fields are explored and in conclusion certain suggestions are made for needed future inquiry into professional knowledge and related topics raised by this thesis.

The purpose of this investigation was to measure the cross section for each of the reactions 87Rb(n, 2n) 86mRb, 112Cd(n, 2n)111mCd, 138Ba(n, 2n) 137mBa and 186W(n, 2n) 185mW at 14.7 ± 0.03 MeV incident neutron energy. The incident neutron flux was determined during each irradiation from the activity produced in copper or aluminum disks between which the isotopically enriched sample was sandwiched. The 63Cu(n, 2n)62Cu and 27Al(n, p)27Mg reaction cross sections were assumed to be 593 ± 45 mb and 73 ± 5 mb respectively. The activity of the sample and monitors was determined by using a 7.6 cm x 7.6 cm NaI(Tl) scintillation spectrometer calibrated with NBS standard sources or by employing the coincidence method in the case of the copper monitors. The measured cross sections in this experiment were 87Rb(n, 2n)86mRb (450 ±51 mb), 112CD(n, 2n)111mCd (400 ± 45 mb), 138Ba(n, 2n) 137mBa (769 ± 87 mb), and 186W(n, 2n)185mW (602 ± 74 mb).

The purpose of this study was to follow the solvent quality curve of the recycle solvent streams of the H-Coal Pilot Plant run by Ashland Petroleum Company at Catlettsburg, Kentucky. This was done with the use of a microautoclave (shaker-bomb liquefaction unit). Several physical and chemical properties of these recycle oils were determined, and these values were correlated with the observed solvent quality. It is shown that the relative, solvent quality of these recycle oils correlate well with many of the chemical and some of the physical properties determined in this study.

The study consisted of two major steps: (1) A macroscopic study was undertaken to determine whether or not the eye and tentacles of a gastropod which exhibits a mosaic development pattern could regenerate. (2) A study was undertaken using histological techniques to determine the detailed step-by-step process of regeneration of the eye and tentacle in Ilyanassa obsoleta.
