The purpose of this investigation is to determine the pressure-flow relationships in the isolated canine cerebral vascular bed. These relationships in vessels which supply an organ surrounded by bone are theoretically influenced by limiting factors which are not present in those vessels surrounded by soft tissue. An evaluation of the extent of these limitations is essential to thorough understanding of the dynamics of the cerebral vascular bed.

Oxygen, nitrogen, and nitric oxide gases were passed through a system consisting of a tungsten filament, an ion gauge, and a mass spectrometer. The ion gauge recorded total pressures and the spectrometer recorded partlal pressures of O/sub 2/, N/sub 2/, NO, CO, COa, and H/sub 2/O. From the way these pressures changed with filamert temperature, the rates of conversion of O/sub 2/ to volatile tungsten oxides and O, and of NO to volatile tungsten oxides N/sub 2/ , O/sub 2/, and O were computed. The time rate of resistance change in the filament was used to compute the rate of conversion of tungsten to tungsten oxides. The filament temperatures ranged from 1950 through 2600 deg K and gas pressures ranged from 10/sup -8/ to 10/sup -6/ atm. For the tungsten-oxygen reaction, the rates of tungsten and oxygen loss were found to depend upon oxygen atom concentration on the surface. The rate of oxide power, depending upon the concentration of oxygen atoms on the surface. The reaction rate at constant oxygen pressure decreases with increasing temperature. For calculational purposes, the tungsten oxygen gas moleeules were assumed to be WO/sub 3/ only, though WO/sub 2/ and WO are other possible products. The …

American dialect studies have progressed rapidly within the last thirty years, but the progress seems to be concentrated within the Southern and New England areas of the United States. Though there have been studies made in other areas, they are sporadic, no work of any significance having yet been published. Texas, unfortunately, is one area of rich dialectal significance which has been neglected, with the exception of Oma Stanley's work on the dialect in East Texas. Even though that work is somewhat dated in many respects, few scholars have seen fit to undertake a revision of Stanley's work or a study of other areas of Texas which would be comparable to The Speech of East Texas. Several master's theses add to the small number of studies concerned with Texas dialects, notably Roy Elders' study of the stressed back vowels in the speech of Parker County, but such studies are also too few. The present investigation was undertaken for the purpose of adding to that collection of Texas dialect studies an examination of the low-back vowels in stressed syllables, of certain diphthongs in stressed syllables, and of the change in frequency of usage of those vowels and diphthongs, occurring within recent …

The equipment and procedure used in measuring the distribution of energy and angle of recoil of neutrons from the reaction pi /sup +/ + p yields pi / sup +/ + pi /sup +/ + n for incident pion mome nta of 1.25 and 1.75 Bev/c are explained. Utilization of the plastic scintillator detectors is given particular attention. Data on the cross section for pion-pion scattering are presented and analyzed. (22 references.) (D.C.W.)

Experimental studies of the relative atomic mu --meson capture probabilities in the constituents of chemical compounds are described. Fermi and Teller had predicted that the atomic-capture probability is proportional to the nuclear charge of the atomic species weighted by its atomic concentration. This is sometimes referred to as the Fermi-Teller Z law.'' Previous experiments indicated no clear systematics to this capture process, and there are conflicts between the results of several measurements made with the same or similar compounds. In these experiments the capturing atom was identified by detection of either mesic x rays or decay electrons from mu /sup -/ mesons bound in the mesic K shell in the atomic species, In these experiments oxides and sulfides of some medium- and high-Z elements as well as two metallic solutions were used, and a nuclear capture product (neutron) rather than the decay electrons was detected. Results show that among the substances examIned, namely CuO, Sb/sub 2/O/sub 3, PbO, CuS, Sb/sub 2/S/sub 3/, PbS AgLi, and CuAu, the Z law'' behavior is not indicated either in insulators or in metals, although in all cases there is a preference for capturing in the atom of higher Z. If the atomic-capture probability is …

The purpose of this study is to examine the relationship between manifest anxiety and orality as related to smokers and non-smokers as indicated on the Taylor Manifest Anxiety Scale and the Blaky Pitres Test (4). From the above theoretical background, the following relationships are hypothesized: Hypothesis I: Smokers will show more anxiety than nonsmokers. hypothesis 2: Female smokers will show more anxiety than male smokers. Hypothesis 3: Among the high anxiety group smokers will show more orality than non-smokers.

The martensite burst transformation was studied in single crystals of iron containing 31.7% nickel. It was found that the morphology of the transformation was greatly simplified in crystals that had heen strained plastically prior to transformation. This simplification made possible detaiied crystallographic studies of the morphology of the transformation. These studies showed that the autocatalysis responsible for the burst transformation had its origin in a mechanical stimulation (coupling) between certain variants of the habit plane that were geometrically oriented such that the stress induced by transformation on one aided transformation on the others. In both strained and unstrained crystals, the most effective mechanical autocatalysis was observed to be between groups of four nearly parallel pianes whose poles clustered about common ( 110) directions. In the transformation of strained crystals, the operation of certain of these groups was favored. These were the groups whose planes were nearly perpendicular to the active slip plane, but did not include the group whose poles clustered about the Burger's vector of the active slip system. This behavior was taken to be a consequence of the anisotropic substructure introduced during deformation. Because of the enhanced transformation by certain groups in strained crystals, the frequency of secondary …

It is the object of this paper to review Sir Edward Elgar's life as a composer, and to discuss and study the thematic elements of his oratorio, "The Apostles." To understand and evaluate the significance of any person's rise to fame in his own field, it is necessary to reconstruct the surroundings from which he came. If a study of the musical conditions had been made when Elgar's development as a composer was starting to draw attention, it would have been noted that the British public was prepared to listen to music in newer forms only if it was from a country other than England. There was very little done or said to encourage any music in a modern character if it was composed by someone from England.

It is the purpose of the present study to add to the growing source of information, so valuable to curriculum makers, by studying the relationship of certain background variables to the Negro girl's curriculum in foods. The background variables included in this study are age, siblings, residence, father's occupation, and mother's education.

This investigation was undertaken to explore biochemical changes which may occur in heart tissue with age. In this connection, the cellular enzymes were of special interest.

The purpose of this paper is to develop some of the more basic Fourier transforms which are the outgrowth of the Fourier theorem. Although often approached from the stand-point of the series, this paper will approach the theorem from the standpoint of the integral.

It was the purpose of this investigation to present laboratory data concerning the assimilation of inorganic nitrogen by the aquatic actinomycetes. The strains of aquatic actinomycetes under consideration represented a cross section of those currently under culture at North Texas State University.

The problem of this study was to determine if significant differences in scores attained by students on academic achievement, problem-solving, and attitudes were associated with closed-circuit television observations. More specifically, the problem was resolved into seeking solutions to the following! 1. Will college students' academic achievement be extended through television observations of children in classroom situations? 2. Will college students' ability to solve problems be improved through television observations? 3. Will college students' attitudes toward teacher-pupil relationships be affected through television observations?

The purpose of this paper is to trace some of the accepted characteristics of the devil to their origins through a study of folklore and ancient religions. The characteristics include the principal form taken by each devil and trace its beginnings through folklore; the animals connected with these devils; powers allotted to these devils; and purposes served by these devils.

The present work is a part of a systematic investigation of the frequency shifts in infrared absorption produced by changing to the anions carbonyl containing acidic compounds.

This sonata by Alban Berg is a product of Arnold Schoenberg's teachings and is, indeed, a musical reflection of the Schoenberg of 1907-1908. At this time the musical thought of Schoenberg himself was in a state of metamorphosis, developing from the chromaticism of the late Romantic composers toward the twelve-tone technique which he was to formulate a few years later. The sonata, as a whole and above all, reflects the growth of an important composer, one who is perhaps the most important link between the traditional Classical and Romantic schools and the modern schools. His growth was based on a thorough knowledge of traditional styles and techniques, vestiges of which are seen in the formal design, chromaticism, and evasive harmony of the work. His advance is seen in his peculiar use of polyphony and motivic variation. Compared with many other works for piano, Berg's sonata is perhaps not among the most celebrated. But as indication of the attitude of a great composer who wished to build upon rather than break with his heritage, it is a most significant work.

The major problem of this study is to identify through the use of the Critical Incident Technique the main requirements for successful ministerial service in the South Carolina Annual Conference of the Methodist Church, insofar as these requirements can be determined through lay observations and judgments. The following sub-problems are closely related to the major problem: 1. What special demands are made upon the minister by special subgroups within the church--e.g., youth, women's groups--in regard to pastoral behavior? 2. How important are the roles assigned to the minister by the church itself--e.g., preacher, teacher, counselor, visitor, administrator, priest? 3. Do churches of varying sizes differ in their expectations of the Ministerial office--e.g., do large churches place greater emphasis upon preaching? 4. Does educational training and/or the salary of the minister correlate with the number of successful incidents reported by respondents?

With the aid of the labor legislation passed during the New Deal era, it would appear that southern labor should have been as well organized proportionately as northern labor. Outwardly it would also appear that southern labor did not enjoy more success in organization because it was still docile and preferred to bargain on an individual basis, an attitude which met with the approval of the southern employer. However, the attitude of the individual southern worker does not explain what occurred in the South under the New Deal. Rather, other important factors retarded unionization: southern community attitudes, regional hostility to anything northern, southern courts, the national aspect of the New Deal and the various unions themselves. To understand the slow but continuous process of unionization in the South during the New Deal period, these factors have to be considered in their setting. Only here can the effect of the New Deal labor legislation be readily discernible.

This paper will attempt to determine whether the increased C'4 previously shown following antigen and adjuvant injection could be correlated to antibody increase following antigen injection.

The purpose of the present study was twofold: (1) to determine if X-irradiation can be considered a direct stress agent, and if so, to what extent it differs from other stressors; and (2) to further elucidate the role of the adrenal cortex in the radiation syndrome by determining the more immediate responses of this system to X-irradiation.

The purpose of this thesis is two-fold: it is (1) to show Emerson's development of a consistent and fully formed theory of education which may well have value for the present time, and (2) to analyze the main aspects of this theory in detail for a better understanding of Emerson's thought.

It is the purpose of this investigation to quantitatively assess the effect of halo in peer ratings of individuals in the areas of friendship, mental ability, and level of anxiety, by identifying the discrepancy between these ratings and the measurement of these characteristics by standardized tests.

The purpose of this study had been to design and test a corona column and an insulating gas distribution system for a small tandem Van de Graaff. The intent of this paper is to describe the gas handling system and to compare experimentally the effects of corona electrode shape on the corona current carried between adjacent sections of the column.

Submitted to Illinois Inst. of Tech., Chicago. A He/sup 3/ cryostat was built to measure the specific heat of rare earth metals which have a component, at low temperatures, attributable to the electrons in the incomplete 4f shell. The specific heat of dysprosium from 0.4 to 4.2 deg K was measured. Pertinent theories about specific heats are outlined. The apparatus included the cryostat, vacuum and He/sup 3/ systems, calorimeter, carbon thermometer, heater, and magnetic thermometer. The experimental procedure is described and results are presented in graphic and tabular form. The specific heat rose sharply below 1 deg K. An anomalous hump was centered about 2.35 deg K. (M.C.G.)
