The plant specimens investigated in this study were collected in Eastern Canada in August, 1969. Other plant specimens studied in this investigation were borrowed from the Gray herbarium of 1tarvard University. Information of three different types was obtained for the different plant specimens. Plants were examined morphologically; they were studied cytologically, to determine their chromosome numbers; and they were investigated chromatographically, to compare tie chromatographic patterns of their free amino acids and secondary substances.Plants identified as P, aviculare and P. arenastrur were found to be separate species based on differences in their morphology, chromosome numbers, and the chromatographic patterns of their secondary substances. Plants identified as P. Fowleri had a diploid chromosome number of 60. On the basis of the chromatographic patterns of their secondary substances. P. Fowleri and P. allocarpum appear to be separate species.Ball State UniversityMuncie, IN 47306

This investigator studied the right upper lobe of the lung in 16 autopsy cases with 11 different systemic and pulmonary pathologies. Four of the lungs were diagnosed as normal, six as emphysematous, and six had other recognizable pathology. Portions of each lung were fixed in Bouin's solution, embedded in paraffin, and sectioned at five microns. They were stained with the Periodic Acid Stain and observed under the phase contrast microscope. The alveolar-capillary basement membrane appeared blue under phase contrast in comparison to the surrounding tissue which was red. There was no statistical difference found in the alveolar-capillary basement membrane width of normal lung versus the emphysematous lung or the lung of a case with any other pulmonary pathology that was studied. The phase contrast microscope proved to be a valuable tool for studying the basement membrane in the lung.Ball State UniversityMuncie, IN 47306

AbstractEugen Bomberger's original work was concerned with the rearrangement of the substituted N-phenylhydroxylamines, but the mechanism responsible for the wide variety of products has remained unsettled.First, this investigation was concerned with a suitable synthesis for the substituted N-alkyl-N-phenylhydroxylamines. Secondly, a better understanding of the mechanism could be accomplished by the identification of the decomposition products and through a kinetic study of the rearrangement utilizing ultraviolet spectroscopy. The study was successful with the product identification of five decomposed substituted N-.phenylhydroxylamines, but numerous products, which interfered with the kinetic study, were isolated from the rearrangement and only uninterpretable kinetic data could be collected.Ball State UniversityMuncie, IN 47306

AbstractThis thesis investigates the mobility and recombination of light injected electron holes as a function of temperature. In this study the n-type germanium samples were placed in potentials which varied from two to twenty-five volts and the temperature varied from just above room temperature to the point where the sample exhibited thermal runaway.In addition, this thesis contains a number of techniques which were developed to complete the general topic. The techniques were in the preparation of the germanium samples, the hole collection circuit, high intensity light sources of short duration, light pulse detectors, and temperature monitoring of a small sample.Ball State UniversityMuncie, IN 47306

AbstractThis thesis has taken an axiomatic system for a finite geometry with a five-point line, introduced definitions of various familiar figures and relationships, and determined properties of the figures in this system. Many of the theorems found herein are true in ordinary Euclidean geometry, but several interesting properties also arise in contrast to the usual.Given consideration in this development are properties of parallelism, perpendicularity, and congruence, in a study of lines, segments, triangles, and quadrilaterals. Also included in the presentation is an introduction to circles and parabolas.Ball State UniversityMuncie, IN 47306

In 1934 the region now known as the Jasper-Pulaski State Fish and Game Area was the subject of a herpetological survey by Major Chapman Grant. This has been the only study directed toward the sand prairie herpetofauna. A reinvestigation of the area seemed worthwhile, and a survey was conducted from April 1, 1971, to October 30, 1971.There seems to have been less change in the amphibian population then in that of the reptiles. One notable exception is Fowler’s Toad, which Grant did not believe to occur at Jasper-Pulaski but which is now very common, while the American Toad is much rarer.The turtle population has changed noticeably. The Mud Turtle and the Spotted Turtle seem to have disappeared.There also have been several changes in the snake population. Grant did not find the Bullsnake at Jasper-Pulaski but did report the Fox Snake as being very common. Now the reverse seems true. The Smooth Green Snake has now become very rare. The Northern Water Snake is apparently now much more abundant.In 1971, a total of thirty species of amphibians and reptiles was recorded in the area: three salamanders, eight frogs and toads, eight turtles, two lizards and nine snakes.Ball State UniversityMuncie, IN 47306
