The Advancement of the Negro within Business and Professional Enterprise in Texas Since 1900

Description: "This research study shall be the advancement of the Negro within business and professional enterprises in Texas since 1900. The objective is to discover if and where the colored people have made progress. If progress has been made, it must be due to some prevailing influence, and if no progress has been made, there has evidently been some hindering cause. This research shall try to discover these factors and record the results as they affected the progress of these people. It is the intention of this writer to race the educational, economic, and social advancement of these people and to show in what fields of endeavor they have advanced and in which fields they have failed. This advancement shall be traced from the year 1900 to the year 1950, showing the progress in ten year intervals."-- leaf 1.

Analysis of supernatants 234-5 Building

Description: The Pu in one batch (160 gms) is precipitated in a purification hood and waste supernatant is then transferred to the storage tank in one of the recovery hoods. Under normal process conditions a small amount of Pu remains in the supernatant. However, it is possible, though extremely unlikely, that the entire 160 grams would be transferred to the waste storage tank. The supernatants are transferred to an evaporator where they are concentrated. This evaporator has dimensions approximately the same as those of the storage tank, however, as concentration proceeds, the remaining solution can pass to a geometry more favorable for a chain reaction. There should be definite assurance before evaporation is begun that the amount of Pu in the evaporator does not exceed 160 grams. It is concluded that there is no objection, from a nuclear safety standpoint, to the discontinuance of analysis of the supernatants.

An Analysis of the Background Data of Fifty Students Who Failed in the College of Home Economics, Syracuse University

Description: The problem of academic failure has been of real concern to the administration and faculty at Syracuse University. The study at hand is concerned specifically with the problem in the College of Home Economics. Through a study of the data known about students at the time of entrance into the College, it was thought that a better basis for selection night be recommended for the admission of students to the College. Such questions as the following arise in the mind of the research worker: 1. Do the group psychological tests given at the University at the time of entrance give us one basis by which we may predict probable academic success or failure? 2. Are the known high school quartiles dependable bases for selection of successful students? 3. Are there factors in the family backgrounds of these students that.may be significant in their selection? 4. Does an objective personality test have validity as a predictive factor in the success of a student? 5. Do we have any anecdotal records that reveal significant differences in personal adjustment between successful and failed students? 6. Are we able to predict the probable success of failed students upon readmission? 7. Do we have any combination of factors that may be significant in predicting the probable success of a student?

A biharmonic relaxation method for calculating thermal stress in cooled irregular cylinders

Description: Report presenting a numerical method for calculating thermal stresses in irregular cylinders cooled by one or more internal passages. The use of relaxation methods and elementary methods of finite differences was found to give approximations to correct values when compared with previously known solutions for concentric circular cylinders with symmetrical and asymmetrical temperature distributions.

Calculated effects of turbine rotor-blade cooling-air flow, altitude, and compressor bleed point on performance of a turbojet engine

Description: Effects of air-cooling turbine rotor blades on performance of a turbojet engine were calculated for a range of altitudes from sea level to 40,000 feet and a range of coolant flows up to 3 percent of compressor air flow, for two conditions of coolant bleed from the compressor. Bleeding at required coolant pressure resulted in a sea-level thrust reduction approximately twice the percentage coolant flow and in an increase in specific fuel consumption approximately equal to percentage coolant flow. For any fixed value of coolant flow ratio the percentage thrust reduction and percentage increase in specific fuel consumption decreased with altitude. Bleeding coolant at the compressor discharge resulted in an additional 1 percent loss in performance at sea level and in smaller increase in loss of performance at higher altitudes.

Cobalt Metabolism of Young College Women on Self-Selected Diets

Description: This study was undertaken to determine the cobalt intake in food and milk, and the excretion of cobalt in the urine and feces of young college women living in the home management house at the North Texas State College and consuming a self-selected diet. Cobalt as a trace inorganic element has long been recognized according to Martin (1945) as a nutritional essential in ruminants in whom cobalt deficiency is a typical anemia. For that reason emphasis has been placed upon studies with ruminants, since it seems logical to use a species for which cobalt is known to be essential.

A Comparative Study of Achievements of Anglo- and Latin-American High School Pupils

Description: "The purpose of this study is to investigate paired groups of Latin-American and Anglo-American children in one community who have attended the public schools approximately the same number of years, to discover difference, if any, in achievement when comparable opportunities for education have been present. Achievement, in this instance, means all phases of the school program: core subject areas, vocational subjects, physical education and health, and participation in extra-curricular activities. Two source of data are utilized in this study: (1) background information concerning the status and accomplishments of the Latin-american child in Texas schools, taken from professional literature in the field and related studies; (2) primary data, consisting of test results and case studies of two selected groups of pupils in the Stuart High School in south Texas, taken from the school records and teacher-observations studies of the Stuart High School ."-- leaf 3.

A Comparative Study of Odessa College, Odessa, Texas, with Business Colleges in the Odessa Area to Determine the Effectiveness of Training Received by Business Students

Description: The potential college students of the Odessa area need to know which type of school best suits their personal needs. The area around Odessa offers the highest paid secretarial Jobs in the state, with some 500 oil and oil supply firms employing from one to fifty full-time secretaries, with salaries ranging from $200 to 4325 per month. The opportunities for accountants, bookkeepers and auditors in the Odessa area is unlimited, and they earn from 4350 to $450 per month. The Odessa area also employs approximately 30 business teachers. 1 The. high school graduate is often at a loss as to whether to take advantage of a business course in a private business college in Odessa or whether to study business administration for one or two years at the local junior college, either in preparation for a job or for additional education at another college or university. A great deal of time and money may be wasted if a potential student attends the school that does not fulfill his needs. In view of the above, the purpose of this study is to make comparisons between the two types of schools in an effort to determine the type of school most suited for each student, and to pave the way for improvements in business education in that area. These facts will be helpful in planning the future curriculum and expansion of Odessa College and the possible establishment of a business school in connection with Odessa College.

Comparison of Measured Efficiencies of Nine Turbine Designs with Efficiencies Predicted by Two Empirical Methods

Description: Empirical methods of Ainley and Kochendorfer and Nettles were used to predict performances of nine turbine designs. Measured and predicted performances were compared. Appropriate values of blade-loss parameter were determined for the method of Kochendorfer and Nettles. The measured design-point efficiencies were lower than predicted by as much as 0.09 (Ainley and 0.07 (Kochendorfer and Nettles).
