Effects of Ribavirin on Normal Rat Kidney Cells and Chicken Embryo Fibroblasts Infected with Rous Sarcoma Virus

Description: Ribavirin, a synthetic nucleoside, was found to inhibit the replication of Rous sarcoma viruses (RSV) and subsequent cell transformation in chick embryo fibroblasts (CEF). It also blocked the transformation of normal rat kidney (NRK) cells infected with temperature-sensitive mutants of RSV. The action of Ribavirin was found to be reversible as removal of the drug from the NRK cells reversed the effects on cell transformation. Ribavirin appears to have a static effect on cell growth of both NRK and CEF cells. In addition, guanosine, xanthosine and inosine altered the effect of Ribavirin on cell growth.

Scientific Reality in C. P. Snow

Description: Twentieth-century science proves that heredity and environment function similarly in all named living species except one--Homo sapiens. Man alone, through his intellect, forms language and culture, thereby affecting his environment so that he participates in the process of his own creation. This participation so links humans that each man extends outside himself creating of the human race a single, whole fabric. C. P. Snow, aware of this communal reality, notes the present lack of communication between scientists and humanists. He contends that this lack, described as the two-cultures split, endangers both the practical survival of Western civilization and mankind's understanding of its own humanity. This study analyzes modern scientific reality and shows that Snow's articles, lectures, and novels articulate that reality and confirm the merit of Snow's observations.

Age-related differences in survival of AKR/J mice treated with anti-lymphocyte globulins, anti-thymocyte globulins, and rabbit anti-mouse brain serum

Description: This investigation was designed to study the age-related differences in the survival rates of 2-to 3- and 6- to 7-month-old AKR/J mice after continuous treatment with anti-lymphocyte globulins (ALG), anti-thymocyte globulins (ATG), or rabbit anti-mouse brain serum (RAMB).

An agonizing evolution: a history of the Texas National Guard, 1900-1945

Description: The National Guard in America began in the Revolutionary War. The Texas units resulted from the earlier concept and emerged in 1835 to resist Mexican oppression. Following achievement of statehood, Texas militiamen served in the Mexican War, the Civil War, and the Spanish-American War. As the twentieth century began, Texans had a long history of service in reserve military organizations in spite of a prevailing attitude of contempt for citizen soldiers held by influential regular army officials.

An Assessment of Occupational Needs and Training Programs in Saudi Arabia

Description: The purpose of this study was to determine (1) the size of the Saudi Arabian manpower shortage in light of the Second Development Plan, (2) the number of skilled and semi-skilled workers that will be graduated from vocational and technical programs during the plan period, and (3) the factors that explain the major causes of the labor shortage problem. In order to accomplish these objectives, the study has considered two questions: (1) Is there a consistency between the manpower needs of skilled and semi-skilled workers and the vocational and technical training programs' output? (2) What are the major factors that explain the labor shortage in Saudi Arabia?

Child Development Knowledge of Adolescents

Description: The purpose of this study was to investigate adolescent knowledge of physical, mental, social, and emotional development of babies and young children. The study was concerned with the effects of the following factors on adolescent knowledge of child development; geographic location, family size, ordinal position, and years of homemaking classes in school. Questionnaires were administered to 200 homemaking students in high schools in Parker and Tarrant counties. The only factor significant at the .05 level in affecting.adolescent knowledge was geographic location. Students from rural high schools obtained higher overall child development knowledge scores than students from urban high schools. Further research to compare the knowledge of students not enrolled in homemaking classes to the knowledge of students enrolled in homemaking classes is recommended.

A Comparison of 4-H Youths' and Their Parents' Attitudes Concerning 4-H Competitive Events

Description: The purpose of the study was to compare the attitudes of 4-H youths and their parents concerning 4-H competitiveness. The sample was composed of seventy-nine 4-H youths and their parents from three North Texas Counties. The instruments, which consisted of an "Opinionnaire for Parents" and an "Opinionnaire for 4-H'ers," were designed to obtain the 4-H'ers' and parents' attitudes about 4-H competition. The study revealed no significant difference in competitive attitudes between 4-H youths' and their parents' or between younger and older 4-H'ers. 4-H boys were found to have more competitive attitudes than 4-H girls. No significant relationship was found between parents' level of competitiveness and length of 4-H service.

A Computer Assisted Drill and Practice System for Introductory Statistics Instruction

Description: To supplement college introductory statistics instruction, an interactive drill system was developed and implemented on a Hewlett- Packard 2000 timesharing computer. Unlimited practice in basic procedures and algorithms was provided over 38 topics including Chi-square, correlational methods, and one-way analysis of variance. Validation of intermediate computational steps was provided, and more difficult or remedial problems sets were made available. Optional files recorded performance data. Four support programs initialized performance files and generated summary reports. Extensive documentation and a library of reusable subroutines were designed to assist future authors to expand the system. The drill and practice system was made generally available to all university departments and students.

Early Function of a Virulent Staphylococcal Phage

Description: Early function of a temperature-sensitive mutant of staphylophage 44A HJD was examined during the twenty-five-minute period following infection. Host cell and phage DNA were labeled with C and3H respectively. DNA was separated into linear and covalently closed circular (CCC) forms by density-gradient centrifugation. The host, S. aureus, shows no CCC DNA, and apparently carries no plasmid. Following infection with wild type phage, CCC DNA forms occur in tritiated and 1 C DNA fractions 10 to 15 min after infection. Infection with mutant at permissive temperature also demonstrates CCC DNA with both labels. Infection with mutant at nonpermissive temperature produced no CCC DNA during the first 25 min after infection. The impaired function in this mutant may be a linker protein.
