Directing Of Mice And Men, James Leavell Edwards

Undergraduate Honors Capstone Projects

The work of the playwright is necessarily an interpretation and reflection of his time. The work of the company in a theatrical production is necessarily an interpretation and reflection of the playwright as he is seen through their own time. These works are readily perceived by the audience in the living theatre experiences through the sensory impressions of their eyes and ears.

In contrast to that which the audience perceives, the world of the director is unknown. Despite the fact that he is the premier artistic coordinator, his job is completed when the curtain rises, with the spectators viewing the …

Integrated Measurement Of Soil Moisture By Use Of Radio Waves, Duane G. Chadwick

Reports

An integrated value of soil moisture can be determine dby measuring the attenuation of vertically-polarized surface radio waves taht are propagated over the ground between a transmitting and receiving atenna. Soil moisture values in the root-zone region were measured over longitudinal distances typically ranging from 50 feet to 600 feet with good results. Integrated soil moisture measurements over greater distances are also possible. Received field strength of propaged radio surface waves closely matches theoretical calculations. The measurement is easily made and does not disturb the soil. Dense, green vegetation, such as alfalfa or corn, causes errors in measurement accuracy. Less …

Canonical Analysis Of Several Sets Of Variables, Chong S. Kim

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Many procedures have been proposed for analyzing and describing multivariate dependence structure.

Partial correlation, multiple correlation, canonical correlation, principal component and factor analysis are used to analyze the dependence structures of a multinormal population.

For a partial correlation analysis it is necessary to decide which variables are to be correlated and which of the remaining variables must be held constant.

Multiple correlation demands that one variable be dependent upon some or all of the remaining variates.

For a canonical correlation, the variables must be collected into two or more sets. The factor analysis technique is for explaining the covariances of …

Solving Three-Dimensional Potential Flow Problems By Means Of An Inverse Formulation And Finite Differences, Allen L. Davis, Roland W. Jeppson

Reports

A finite difference method is developed to solve the three-dimensional, steady, incompressible, potential flow equations obtained by using a potential function, o, and two mutually orthogonal stream functions, u and u*, to describe the flow. Problems are formulated in an inverse space where the potential function and the two stream functions are the independent variables, and the Cartesian coordinates x, y, and z are the dependent variables. The boundaries of the problem in the physical space, including the free surface, have known positions in the inverse space, so trial and error adjustments to the positions of the boundaries are unnecessary. …

The Interaction Of Promazine With Selected Macromolecules And A Membrane Utilizing Absorption And Emission Spectroscopy, Jess D. Keeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of promazine-HCl with bovine serum albumin, ammonium detergent micelles, and hemoglobin-free-rabbit-erythrocyte membranes were measured using the changes in the absorption and the emission of the interactants plus the fluorescent probe 1-anilino-8-naphthalene sulfonate. The binding of a promazine to serum protein and membrane did not alter the emission of the drug. However, the binding did produce a measurable quenching of the membrane and protein fluorescence. The quenching reaction was pH sensitive for both the protein and the membrane. Promazine binding to serum protein produced a hyperchromic change in the drugs absorption spectrum which paralleled the quenching reaction. The binding …

A Simple Microradiometric Technique For The Rapid Measurement Of Monoamine Oxidase Activity In Rat Testicular Minced And Teased-Tubular Preparations, Ronald L. Urry

Biology

Two radiometric techniques are described for the measurement of monoamine oxidase activity in testicular tissue preparations. These techniques utilize 5-HT-2-¹⁴C (serotonin) as the substrate and measure its conversion into 5-HIAA-¹⁴C (hydroxy-indole acetic acid). The first technique described uses a substrate concentration of 0.9 µM (0.05 µCi) in an incubation volume of 3.1 ml and 120 mg of teased-tubules. Samples are incubated 1 hour. This assay was found suitable for use with teased-tubule preparations but not for preparations containing interstitual cells. An inhibitor was present in the interstitual cell preparations which at the low substrate concentrations used …

The Regulation Of Purine Biosynthesis In A Phosphoribosylpyrophosphate Aminotransferase-Deficient Mutant Of Salmonella Typhimurium, Wen-Cherng Tsai

Biology

The regulation of the alternate first enzyme of purine de novo synthesis (ribose-5'-phosphate aminotransferase) has been examined in pur-F 341, a purine-requiring mutant of Salmonella typhimurium deficient in the primary first enzyme (PP-ribose-P amidotransferase, EC 2.4.2.14). The ribose-5'- phosphate aminotransferase is feed-back inhibited by AMP, ADP, GDP and adenosine but not by ATP, GTP, GMP and free adenine. Pyrimidines (except CDP and UDP) and thiamine compounds show no significant inhibitory effect on ribose-5'-phosphate aminotransferase activity. The alternate enzyme seems to be also controlled at the gene-level by one or more intra-cellular purines (repression-derepression). The role of the aminotransferase in …

Homeotherm Productivity And Activity As A Function Of Microclimatological Variables, June K. Rushing

Biology

The purpose of this paper is to advocate the use of computer modeling as a tool in the study of homeotherm energetics. The relationships between measurable environmental variables and components of productivity were reviewed and discussed as a basis for data input in the models. Photoperiod, temperature, rainfall, and wind were suggested as measurable environmental parameters. The facets of productivity which can be predicted from these parameters are the timing, the energetic cost, and the energetic capacity for productivity.

Amino Acid And Protein Metabolism During Development Of The Alfalfa Weevil Hypera Postica (Gyllenhal), Darrel J. Gunderson
