A Study of the Previous Public Senior High School Physical Education on Experiences of Freshman Girls Enrolled at North Texas State College for the Spring Semester, 1960, with Recommendations for the Curriculum in the Area of Physical Education for Service Classes at North Texas State College

A Study of the Previous Public Senior High School Physical Education on Experiences of Freshman Girls Enrolled at North Texas State College for the Spring Semester, 1960, with Recommendations for the Curriculum in the Area of Physical Education for Service Classes at North Texas State College

Date: August 1960
Creator: Curtis, Joyce Mae
Description: The investigator became interested in the question, "What is the typical high school background in physical education of freshman girls enrolled in Texas colleges." The investigator was particularly interested in the background of freshman girls enrolled in North Texas State College. On the basis of the above interest, the investigator undertook a study of the previous public senior high school experiences in physical education of freshman girls enrolled at North Texas State College for the spring semester, 1960, with recommendations for the curriculum in the area of physical education for the college service classes.

A Study of the Processing Properties of Hard-Particle Reinforced Composite Solders

A Study of the Processing Properties of Hard-Particle Reinforced Composite Solders

Date: May 1994
Creator: Calderon, Jose Guadalupe
Description: The microstructural, mechanical and thermal properties of various composite solder formulations were investigated. Special interest was given in observing the processing properties, microstructural characteristics, fatigue behavior, tensile strength, and the effect of environmental ageing on the composite solder formulations. The solderability parameters wetting and speed of soldering, reflow temperature, and the thermal stability of the resulting composite solder were also examined.

A Study of the Pyrimidine Biosynthesis Pathway and its Regulation in Two Distinct Organisms:  Methanococcus jannaschii and Pseudomonas aeruginosa

A Study of the Pyrimidine Biosynthesis Pathway and its Regulation in Two Distinct Organisms: Methanococcus jannaschii and Pseudomonas aeruginosa

Date: December 2001
Creator: Patel, Seema R.
Description: Methanococcus jannaschii is a thermophilic methane producing archaebacterium. In this organism genes encoding the aspartate transcarbamoylase (ATCase) catalytic (PyrB) and regulatory (PyrI) polypeptides were found. Unlike Escherichia coli where the above genes are expressed from a biscistronic operon the two genes in M. jannaschii are separated by 200-kb stretch of genome. Previous researchers have not been able to show regulation of the M. jannaschii enzyme by the nucleotide effectors ATP, CTP and UTP. In this research project we have genetically manipulated the M. jannaschii pyrI gene and have been able to assemble a 310 kDa E. coli like enzyme. By using the second methionine in the sequence we have shown that the enzyme from this organism can assemble into a 310 kDa enzyme and that this enzyme is activated by ATP, CTP and inhibited by UTP. Thus strongly suggesting that the second methionine is the real start of the gene. The regulation of the biosynthetic pathway in Pseudomoans aeruginosa has previously been impossible to study due to the lack of CTP synthase (pyrG) mutants. By incorporating a functional uridine (cytidine) kinase gene from E. coli it has been possible to isolate a pyrG mutant. In this novel mutant we have ...

A Study of the Qualifications and Status of Industrial Arts Teachers in Texas

A Study of the Qualifications and Status of Industrial Arts Teachers in Texas

Date: August 1967
Creator: Moore, Billy M.
Description: This is a study to ascertain the current qualifications and status of the industrial arts teachers employed in the elementary, junior, and senior high schools in the state of Texas. The purpose of this study is threefold: 1) to hypothesize that the qualifications and status of Texas industrial arts teachers have improved within the last fourteen years; 2) to hypothesize that those industrial arts teachers who were active in professional organizations have higher academic qualifications and status than those teachers who were not active in professional organizations; and 3) to hypothesize that industrial arts programs under the guidance of those teachers who were active members of professional organizations had a more complete industrial arts program and offer a wider selection of courses than those not.
