A Multiphasic Study of the Interaction Between the Branchiobdellid Cambarincola Vitrea and its Crayfish Host Procambarus Simulans

Description: The host-parasite interface between the branchiobdellid Cambarincola vitrea Ellis and its crayfish host is investigated along ecological, ultrastructural, serological, and endocrinological lines of evidence. Monthly analysis of a natural branchiobdellid from a vernal habitat demonstrates the annelid to be particularly sensitive to changes involving both the physical habitat as well as the host crayfish.

Evaluation of Immune Responses and Cytological Changes in Lumbricus Terrestris and Eisenia Foetida as Assays for Xenobiotics

Description: The earthworms, Lubricus terrestris and Eisenia foetida, were used as non mammalian surrogate models to assess the immunotoxicpotential of xenobiotic to mammals. Assays were developed and optimized for detecting spreading activity and phagocytosis of rabbit red blood cell (RRBC), bacteria, and yeasts by macrophage-like coelomocytes of L. terrestris.

Induction of Interferon Messenger RNA and Expression of Cellular Oncogenes in Human Lymphoblastoid Cells

Description: The purposes of this study was to demonstrate the induction of alpha interferon mRNA in Sendai virus-induced Namalava cells, to follow the level of alpha interferon mRNA synthesis at the transcriptional level, and to determine whether the Namalava cell line expresses the c-myc oncogene and to what degree. The amount of c-myc message deteted in Namalva cell RNA was about one-tenth that of Daudi cell RNA, whereas no difference in the amount of the c-Ha-ras message was observed between the two cel… more

Variations of the Mouthpiece Chamber and Their Effects on the Harmonic Spectrum of the Alto Saxophone

Description: It is the intent of this study to describe the harmonic activity that is present in the tone of the alto saxophone and to compare the spectra of selected tones when the chamber of the mouthpiece is changed in size and shape. It is hoped that the following questions might be answered: 1. What does the harmonic spectrum of the alto saxophone contain in terms of harmonic activity and the relative intensities of these harmonics? 2. What basic changes in chamber shape and size have evolved from earl… more

Characterization of the Specificity of DNA Uptake and Transformation by Naturally Competent Acinetobacter Calcoaceticus

Description: Although cultures of A. calcoaceticus BD413 are naturally competent at all growth phases, genetic markers can only be successfully transformed by DNA from the genus Acinetobacter. Transformation frequencies of nearly 1.2% were obtained with pcaA mutants were incubated in liquid culture with wild-type DNA.

German singing Societies in Texas

Description: The Germans who immigrated to Texas in the 1830s, 40s, and 50s brought with them many and varied cultural institutions which they had known and enjoyed in Europe. As soon as the initial hardships of the frontier could be overcome, they eagerly established singing societies in the Lidertafel tradition. These organizations were to have a profound impact on music in Texas from about 1850 to the time of World War I.

The Mercury Photosensitized Reactions of Some Hydocarbons

Description: The problem was to study several hydrocarbons when they were subjected to ultraviolet light of 2536 Å in the presence of mercury vapor. It would be expected from the work of Stallings that the rupture of any tertiary hydrogen bond in the molecule would be the predominant effect. However, secondary and primary bond splitting would occur as well as some C-C bond rupturing, but these could be expected to a lesser degree than the first, since the t-hydrogen has the greatest reactivity.

Compliance-Gaining Among Anglo and Mexican-American Children

Description: This study investigates compliance-gaining rhetoric among Anglo and Mexican-American fourth graders in three schools in north Texas. The children were asked to respond to a scenario and to give a rationale for their persuasive strategies. An analysis of interviews with 52 children indicates that although the children used some similar strategies when attempting to gain compliance from an adult, there are also some significant differences between the two cultural groups.

Expanded Plastics Used as Sculptural Patterns for Burn out in Ceramic Shell Molds

Description: The purpose of this investigation was to develop a method of burning out expanded plastic patterns invested in ceramic shell molds. Technological information suggested that the procedure was not feasible because plastic expansion or gas combustion invariably spoiled the mold. However, burning out expanded plastic patterns would provide a practical method of using such materials in the sculptor's studio; combined with ceramic shells, the patterns would promote accurately detailed castings with e… more

Organelle- and Organ-Specific Isozymes of Euglena Gracilis and Catfish

Description: Two distinct compartmentalized isozymes of aldolase and triosephosphate isomerase were examined in the photoautotrophically and heterotrophically grown green alga Euglena gracilis. A comparison of the chemical and physical properties of the isozymes was carried out. Isozymes of phosphoglucose isomerase were isolated in homogeneous form from liver and muscle tissue of the fresh water catfish. The two organ-specific isozymes were essentially identical with respect to their molecular weights but e… more

A Comparison of Drawings Between a Group of Dyslexic Adolescents and a Group of Non-Dyslexic Adolescents

Description: The purpose of this paper is to compare a group of adolescents with the learning disorder of dyslexia and a group of adolescents without dyslexia in regard to their ability to make realistic drawings. Subjects selected for the study were from a suburban junior high school in which a random sample was taken of both dyslexic and non-dyslexic students. Each was given three standardized drawing tasks, including a still-life drawing, a contour drawing, and a perspective drawing. The drawings were ju… more

Primary Productivity and Nutrient Relationships in Garza-Little Elm Reservoir

Description: A large, multi-basin reservoir (Garza-Little Elm Reservoir) in north central Texas was studied to determine the relative effects of various parameters on primary productivity. The basins were impounded several years apart, thus allowing the influence of age on water chemistry and biota to be considered. Another principal influence on water quality was secondary sewage effluent that entered one basin from a nearby source.
