The Present Practices of School Business Managers in the Schools of Texas

Description: The purpose of this study is to determine the present practices with respect to business managers in the school systems of Texas. This study attempts to determine from present practices what the business manager's duties and qualifications are; what the scholastic population of a school should be in order to employ a business manager; what the relationship of the business manager to the superintendent and the school board is; what experience and training the business managers have had; what the salaries of business managers are; what the trends in the employment of business managers are; and from what fields business managers are drawn.

Factors Contributing to the Transiency of Elementary-School Principals in the State of Texas

Description: It is the purpose of this study to discover factors contributing to the transiency of elementary-school principals by a study of (1) educational experiences of principals, (2) academic and professional qualifications of principals, (3) tenure of principals, and (4) motives for changes made by elementary-school principals.

A Comparison of the Achievements of Science and Non-Science Majors Enrolled in General Chemistry at North Texas State College

Description: It is the specific purpose of this investigation to determine the difference, if any, in the amount of practical, everyday chemistry learned by the science majors as opposed to the non-science majors enrolled in general chemistry at the North Texas State College during the school year 1950-1951.

A Lunchroom Study of Specific Elementary, Junior, and Senior High Schools in the City of Dallas

Description: The present study was made without benefit of poster, films, bulletin board, or other teaching aids. It was undertaken to determine the nutritive values of the menus served, the foods selected by the plate lunches, and the amount of food wasted in two elementary, two junior high, and two senior high school lunch cafeterias in the City of Dallas during a six month period of time.

Electrodeless Discharge of Isopropyl Alcohol

Description: Gases at satisfactory pressures fluoresce in the presence of radio frequency radiation (6). Such fluorescent gases have been used to probe fields of radio frequency oscillation and their emission spectra have been recorded and studied. Ions with multiple charges also exist in these gases, (6). In 1941 Oliver (12) observed the fluorescence of an isobutane- isobutene gaseous mix flowing to a pump through a glass tube which was wrapped by a spiral antenna of a sevenmegacycle transmitter. A white deposit was noticed at a bend in the tubing on the pump side of the fluorescing section of the gas (12, p. 8). In 1957 Blacknall (3) studied the fluorescence and reaction products of propylene in the antenna region of sevenmega- cycle radiation, The oscillator employed by Blacknall was an ARC-5/T-22 military surplus transmitter of range 7.00 to 9.10 megacycles, which he operated at 7.00 megacycles. Blacknall observed a drop in pressure and the formation of a brown deposit in the region of the coil. Blacknall did not report an analysis of this product. In 1959 Armstrong (1) repeated Blacknall's experiments and modified Blacknall's apparatus into an improved design. He also performed an analysis on Blacknall's product. Blacknall used a vertical open-end mercurial manometer with which to measure pressure in his system and as a result introduced mercury vapor into his system. Armstrong tried to minimize the amount of mercury introduced by covering his manometric mercury with a layer of octyl sebacate, "octoil". Armstrong used a spiral-would antenna wrapped around his reaction vessel and reported the formation of spiral brown rings coincident with the copper wire of the antenna. There was a white product deposited in a spiral interlaced with the spiral of dark brown material. No definite identification was reported by Armstrong other than reporting, his solid material as isotactic ...

Selective Lipid Absorption

Description: An experiment was designed to study in the same animal any preferential absorption of a free fatty acid in the presence of a triglyceride of the same fatty acid. Rats were administered a mixture of free fatty acid and its triglyceride labeled with carbon-13 and carbon-14 respectively. Each isotope in the fed lipid and in the lipid recovered from the gastrointestinal tract was measured. The isotope effect, if any, was studied by administering a mixture of palmitic acid-1-C13 and palmitic acid-1-C14.
