The Sensitivity of Human Blood Plasma to the Coagulase Enzyme Secreted by Members of the Genus Micrococcus
Date: 1950
Creator: Coultas, John T.
Description: The problem in this investigation consisted of, first, the isolation from human sources and identification of thirteen cultures of typical micrococci to be used as test organisms; second, the acquisition of blood plasma from thirty different human beings; and third, the determination of the possibility of individual variation in sensitivity of blood plasma to the micrococci used as test organisms as revealed by the coagulase test.

Protective Effect of Specific Heterologous Anti-Mouse Tumor Serum
Date: August 1961
Creator: Culpepper, Thomas James
Description: The principal purpose of this work was to determine the effect of immunized guinea pig serum upon the survival time of tumor infected mice, and to make a correlation between this effect and the complement titer.

Assimilation of Inorganic Nitrogen by Aquatic Actinomycetes
Date: August 1962
Creator: Davis, Ernst M.
Description: It was the purpose of this investigation to present laboratory data concerning the assimilation of inorganic nitrogen by the aquatic actinomycetes. The strains of aquatic actinomycetes under consideration represented a cross section of those currently under culture at North Texas State University.

A Determination of the Effects of Various Concentrations of Sodium Chloride upon the Growth of Three Species of Bacteria
Date: 1942
Creator: Davis, J. Floyd
Description: The problem in this investigation is to determine the effects of various concentrations of sodium chloride upon the growth of three species of bacteria. An effort has been made to solve this problem, not only by a study of the relevant literature, but also by laboratory research consisting of cultivation and observation of the three organisms which were arbitrarily chosen for this study.

A Study of Some Congenital Anomalies of the Hands and Feet
Date: 1950
Creator: Davis, Ralph Waldo
Description: This paper has been undertaken, first, to contribute several more cases of various congenital anomalies to the literature on human genetics, and, second, by an analysis of the genealogies, to determine the possible modes of transmission of these anomalies.

Anatomical and Morphological Responses of Cardiospermum Halicacabum L. (Balloon Vine), to Four Levels of Water Availability
Date: May 2011
Creator: Dempsey, Matthew Anthony
Description: C. halicacabum (Sapindaceae) is an invasive plant that is considered a nuisance species in Texas riparian environments. Little is known of the tolerance of C. halicacabum to flooding and drought; however, this information may provide insight into the characteristics that contribute to C. halicacabum purported invasiveness. C. halicacabum seedlings (n = 92) were exposed to one of four levels of water availability (flooded, saturated, intermediate and dry) over six weeks under greenhouse conditions. Plant performance was affected by water availability; however, there was no effect on survivorship. Flooded and saturated plants exhibited morphological adaptations; producing adventitious roots, hypertrophy, and aerenchyma tissue. Morphological measures, anatomical responses, and patterns of biomass allocation all indicate that C. halicacabum is able to survive periodic inundation, perform in saturation, and establish and thrive on the drier end of a moisture gradient.
