Opthalmic Use Of Sodium Cephalothin: An In Vivo Comparison (open access)

Opthalmic Use Of Sodium Cephalothin: An In Vivo Comparison

A rabbit keratoconjunctivities model was used to evaluate ophthalmic formulations containing 1 percent sodium cephalothin in silicon oil, a 1 percent sodium cephalothin aqueous solution, and a 0.3 percent gentamicin sulfate solution. Rabit eyes were inoculated intracorneally with Pseudomonas aeruginosa, Staphylococcus aureus, or Streptococcus pneumoniae, After topical treatment, none of the antibiotic formulations were effective in the P. aeruginosa model; all three showed good activity against S. aureus, and against S. pneumoniae, the caphalothin formulations were more effective than gentamicin.In a related stability study, the cephalothin potency of the silicon formulation was maintained for 16 weeks at 4, 25, and 450 C These studies suggest that sodium cephalothin can be formulated as an effective and stable ophthalmic dosage form.

Scientific Reality in C. P. Snow (open access)

Scientific Reality in C. P. Snow

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.

Effects of Cigarette Smoke Condensates on Cultured Human Lymphocytes and Separation of Benzo-α-Pyrene Metabolites by High Pressure Liquid Chromatography (open access)

Effects of Cigarette Smoke Condensates on Cultured Human Lymphocytes and Separation of Benzo-α-Pyrene Metabolites by High Pressure Liquid Chromatography

Cigarette smoke condensates from all cigarettes tested were found to be potent inducers of AHH enzyme in cultured human lymphocytes and, with the exception of Kent Lights and Carlton CSC's, all were found to be toxic under the experiment conditions. Most of the AHH inducing activity was found in basic and neutral fractions of the lAl standard cigarettes. A radiometric assay of BP metabolites in cultured human lymphocytes was developed in which we were able to separate the primary metabolites and the secondary metabolites from the parent compound (BP) by neutral alumnia HPLC. The primary metabolites were further separated by a selective enzyme hydrolysis and/or reverse phase HPLC.

Thundershowers: A Novella, with a Commentary (open access)

Thundershowers: A Novella, with a Commentary

Thundershowers, an original novella, represents one person's perception of relationships between women and men. The first-person narrator, Anna Slone, records her limited observations of married and unmarried couples while she pursues her own involvement with a man. She observes nothing admirable in any of the relationships between men and women in the story, and her own romance falls short of her expectations. The only nurturing love that she records passes between herself and two other women, her mother and a friend. Thundershowers is not meant to be a suggestion that all woman-man relationships are soulless or that real love can exist only between women. Set in a Colorado resort, the action focuses on several concurrent love-interests, including a faltering marriage, a traditional marriage, the engagement of two young lovers, a lighthearted sexual affair, and the short-lived but painful romance of Anna and a man whom she meets at the resort.

Young Married Couples' Attitudes Toward Children (open access)

Young Married Couples' Attitudes Toward Children

This study investigated the relationship of certain independent variables and young married couples' attitudes toward children. Church leaders in Plano, Texas, administered the Hereford Parent Attitude Survey to couples from their churches. Ninety-seven subjects comprised the main sample group. The data were analyzed using t-tests and f-tests. Women had more positive attitudes toward children than men. Parents had more positive attitudes than childless subjects. Childless subjects who plan to have children had more positive attitudes toward children than subjects who did not plan to have children or who were not sure. Income level was related to confidence in parenting. Age and sex of children and education level were not related to attitudes toward children. Based on these findings, recommendations were made for future research and education.

The Effects of Selection Risk on Sex Discrimination in Employment Decisions (open access)

The Effects of Selection Risk on Sex Discrimination in Employment Decisions

Effects of selection risk on sex discrimination in hiring were investigated. Ninety-six male and female educational administration graduate students rated ficticious resumes on suitability for hiring for the female-oriented position of secondary school teacher. Sex and selection risk level were varied, with sex of rater as an assigned factor. Analysis of variance yielded significant main effects for sex (p < .01) and selection risk level (p < .05). All ratings were lower in high selection-risk situations, with males preferred over females across both levels of risk. Results suggested that ratings were based on a stereotype of female inferiority in work efficiency, overriding job sex-orientation as a decision factor.

San Juan Ixcoi Mass: A Study of Liturgical Music in Northwestern Guatemala (open access)

San Juan Ixcoi Mass: A Study of Liturgical Music in Northwestern Guatemala

The San Juan Ixcoi Mass is part of the San Miguel Acatan Repertory which was found in the northwestern highlands of Guatemala before being purchased by the Lilly Library at Indiana University. Even though the authorship and date of the mass cannot be established, the mass is similar to works from the Josquin generation. Not discounting the few transcription difficulties as well as isolated compositional weaknesses, the San Juan Ixcoi Mass demonstrates the reasonably high quality of music that was performed and even possibly composed in northwestern Guatemala three centuries ago. A modern performance edition of the mass complete with critical notes and commentary on the transcription is included within the thesis.

Dehumanization in the Theater of Valle-Inclán and Muñiz (open access)

Dehumanization in the Theater of Valle-Inclán and Muñiz

This study proposes to establish an intrinsic relationship between Valle-Inclán and Muñiz based on the theme of dehumanization in their theater. It examines (1) the stylistic techniques which each playwright uses to depersonalize his characters, (2) the manner in which these characters dehumanize each other, (3) the role of society as the agent of dehumanization, and finally, due to each author's preoccupation with one social convention in particular (4) the devastating effects on men of the vestiges of an outmoded code of honor. The principal works used for the study are Valle-Inclán's Martes de carnaval, Luces de Bohemia, and Divinas palabras, and El tintero, Un solo de saxofón, Las viejas difíciles, and El grillo by Carlos Muñiz. Such an analysis proposes to reveal a profound literary affinity between these two writers, a bond which unites Valle-Inclán and Muñiz in a common protest against the dehumanization of mankind.

Effect of Operant Behavior on the Metabolism of 5-Hydroxytryptamine (open access)

Effect of Operant Behavior on the Metabolism of 5-Hydroxytryptamine

The role of operant behavior in the metabolism of brain 5-hydroxytryptamine (5-HT) turnover was investigated. Two and one-half hours following the administration of 150 mg/kg of para-chlorophenylalanine (PCPA), a specific inhibitor of tryptophan hydroxylase, levels of 5-HT were compared in sedentary and performing rats. Whole brain levels of serotonin were reduced in both responding and sedentary animals; however, differences between these groups were not statistically significant. The drug induced decrease in 5-HT levels was accompanied by a significant decrease in session responding. The degree of suppressed responding could be correlated with the level of 5-HT following PCPA, suggesting that the metabolism of serotonin is in part modulated by the rate of responding as maintained by the operant schedule.

Notes on the SWTPC MP-N Calculator Interface and the Calc-1 Program

This interface was bought to perform floating-point arithmetic and for its function capabilities such as SIN, COS, and e^x. My application required an integer truncation function that is not performed by this calculator, so i wrote a small assembly language subroutine to do it. A potentially irritating problem is that the calculator chip does not automatically convert to scientific notation if the numbers become too big to display in floating point. The control program must keep track of the display mode.

VISOR (Variable Interval Schedule Of Reinforcement) System Documentation (open access)

VISOR (Variable Interval Schedule Of Reinforcement) System Documentation

This program will be used in operant behavior research to monitor and record responses and trigger and record reinforcements on a variable reinforcement (VI) schedule. The original application of this program will be the servicing of several rat cages simultaneously. The response will be the pressing of a metal bar in the cage, the reinforcement will be the triggering of a feeding mechanism which disperses a food pellet into the cage. The subsequent applications of this program are not limited, in that the actual response and reinforcement devices and the subject type are all treated indifferently by the program.

FORTRAN Graphics Library (open access)

FORTRAN Graphics Library

The objective of this work is to help the faculty, staffs and students of NTSU to use the CalComp plotting facility very easily. Therefore, this work is written in such a step by step and self-explanatory way to help the reader to understand and grasp the essential technique of the computer plotting. Each subroutine illustrated in this work has been run and checked by our NTSU computer-CalComp plotting facility; the results of sample programs and illustrated graphs are believed to be very useful to understand each individual subroutine. Basically, software packages are stored in the magnetic disk of the IBM 360 computer as the standard graphic subroutines. These subroutines were written in FORTRAN IV. The user can write the driving program to call these subroutines and also inputs the desire data to the computer for computation. The results of computation will be outputed and stored in the magnetic tape.

PILOT for the Apple II Microcomputer (open access)

PILOT for the Apple II Microcomputer

PILOT (Programmed Inquiry, Learning or Teaching) is a simple, conversational language developed in 1969 by John A. Starkweather at the University of California Medical Center in San Francisco. Originally designed for computer assisted instructional needs, PILOT also has been effectively used as an introductory computer language. The PILOT system developed for the Apple II microcomputer consists of two programs, PILOT EDITOR and PILOT DRIVER, which are written in Applesoft and which use the Apple II disk operating system. The PILOT system was designed to facilitate easy authoring and execution of programs written in an extended version of the PILOT language. Due to the memory requirements of the programs and the Apple II disk operating system, the PILOT system described here should be executed on a machine with at least 32k bytes of random access memory.

Dreams as a Source of Imagery (open access)

Dreams as a Source of Imagery

Dreams can be defined as a series of thoughts, images, or emotions that occur during sleep. The impression of strangeness, which is certainly a characteristic of dreaming, comes from three primary performances: (1) a loosened temporal and spacial world, (2) short attentional controls and (3) fewer critical evaluations. In dreams, time and matter are not bound by physical properties, and scenes may change with remarkable rapidity or awesome slowness. One out of three people can recall dreams upon awakening. During a night's sleep there are usually three separate dream periods per night, which contain at least two dream stories within each period.

The Neutralization of the Figure Within a Controlled Environment (open access)

The Neutralization of the Figure Within a Controlled Environment

The questions I have addressed in regard to neutralization were as follows: 1. How important was the figure to the environment? 2. How far could the figure's physical presence be reduced and still contribute to the concepts of the painting? 3. How vividly was the figure presented while still complying with the requirements to meet neutralization? 4. Did color and texture aid in neutralizing the figure, and, if so, how? 5. Did the scale of the paintings have any effect on the neutralization process?

Printmaking Experimentations: A Personal Approach

Experimentations with overlays of color within my imagery have developed an interest in surface embellishment resulting from the juxtaposition of overlapping hues, integration of collage, and extended use of mixed-media as a printed visual statement. Past printmaking experiences include exploration of a variety of procedures including lithography, intaglio, and serigraphy. Prints have been executed in edition and monoprints, singular techniques and in combination. Individual techniques were expanded through the use of collage and linear application of graphite.
