In making this study it is important to search for ways to enhance and, if possible, make detection of MMO signals simpler in order that this technique for obtaining FS measurements may be extended to other materials. This attempt to improve measurement techniques has resulted in a significant discovery: the eddy-current techniques described in detail in a later section which should allow MMO to be observed and sensitively measured in many additional solids. The second major thrust of the study has been to use the newly discovered eddy-current technique in obtaining the first indisputable observation of MMO in zinc.

In these studies several different types of antimetabolites were synthesized, and their biological effects were examined in various assay systems. More extensive investigations were done in microbial systems in which many of the compounds proved to be inhibitory to growth, and attempts were made to determine the mode of biochemical action by adding supplements of the appropriate natural metabolite.

This investigation was concerned with three aspects of the problem of passive dispersal of algae and protozoa by aquatic insects: the role of odonates in passive dispersal of viable small aquatic organisms, the passage of viable algae and protozoa through digestive tracts of field-collected herbivorous and carnivorous aquatic insects, and the viability duration of selected algae, during insect transport under monitored conditions.

The purpose of this study was to determine if seminary students, identified as conservative, moderate, or liberal in theological beliefs, were significantly different on the following personality variables: dogmatism, thinking introversion, theoretical orientation, aestheticism, complexity, autonomy, religious orientation, impulse expression, anxiety level, practical outlook, and personal integration. The instrument used to measure theological beliefs was the "Inventory of Theological Beliefs." Dogmatism was measured by the "Rokeach Dogmatism Scale." All other variables were measured by the Omnibus Personality Inventory.

The chansonnier held by the Biblioteca Casanatense in Rome, designated Codex 2856 (0. V. 208), is a handsome volume containing 123 polyphonic compositions in the style of the Franco-Flemish School, circa 1450 to 1400. Although no text beyond the incipit is found in the manuscript, the value of the source is enhanced by the names of the composers of 106 of the compositions. Volume one focuses on the manuscript, giving a physical description of the manuscript, recounting the history of the manuscript, and includes discussion of selected composers and a concordance. Volume two contains the music of the chansonnier Biblioteca casanatense 2856.

The scope of this study is limited to Federal military occupation during the five years from 1865 to 1870. Only the interior counties, where a dense Negro population required the exercise of political and social responsibilities, will be considered in detail. A line from Wise through Bosque, Travis, Wilson, Karnes, and Goliad Counties to the coastal town of Corpus Christi would roughly separate interior from frontier posts.

Favorable judgment of a work of art, or of a man, usually means that the work of art, or a record of the man, will be preserved for future generations to judge for themselves. An unfavorable judgment may result in a richly deserved obscurity or an irreplaceable loss, unless favorable circumstances combine to preserve the evidence for a more perspicacious generation. One can be forgiven if he distrusts history's judgment; mistakes which have been corrected are legion (the case of J. S. Bach comes most vividly to mind) and skepticism is warranted unless or until the facts are available for confirmation. It is difficult to explain the paucity of information about Jacques-Christophe Naudot, Not that he is another J. S. Bach; neither Fleury, who made the first serious effort to revive interest in his music in the early 1920's, nor Ruf, who has done much in this regard recently, nor this writer makes any such claim. He does not, however, deserve the obscurity that has been his lot. If his music is not always profound, it nevertheless has both intrinsic and historical value, and some of his works reveal considerable contrapuntal skill. It may be that Naudot stood in the …

Accurate identification is fundamental in any study of grasses by farmers, ranchers, range specialists, ecologists, or students interested in the changes taking place in the grass habitat. Frequently it is convenient, and sometimes it is necessary, to identify the grasses by their vegetative characters. Some are readily recognized at a glance by their habitat and certain characters well known to the experienced observer. In other cases, identification is more difficult; and, perhaps with a few, it is impossible to be certain of the species from vegetative characters. However, this may also be true when the characters of the floral parts alone are considered. The inflorescence, used in most keys and descriptions, is often available only for a short period of time. Identification by the characters of the vegetation can be used throughout the growing season, even if grazing or mowing has removed or prevented the development of the floral parts. There have been other studies of grass identification related to vegetative characters, but they have been local and have not covered North Central Texas. This paper provides a means of identifying grasses by their vegetative characters. It can be used by the scientist, the technician, and the layman interested in …

Iodoacetamide has been shown by others to be a radiation sensitizer for bacteria and for certain mammalian cells tested in vitro. This work describes an examination of the effectiveness of iodoacetamide used in vivo. Survival of ascites tumor cells maintained in the peritoneal cavity of mice was used as an indicator of sensitization. Survival was assessed using TD{sub 50} and total tumor cell population determination methods. A comparison of results obtained by these methods is made. The effects of oxygen tension and radiation dose rate upon results was examined. Iodoacetamide was found to be effective as a radiation sensitizer under all conditions although to a lesser degree than that reported by others for in vitro experiments with bacteria. Radioactive tracer studies indicate that iodoacetamide has rapid and total access to most if not all tissues of the body. This fact coupled with the observation of a sensitization in an in vivo system where the anoxia so prevalent in well developed tumors was present, suggests the possibility of clinical usefulness of iodoacetamide in cancer radiation therapy. Certain observations are reported on the effect of various cell and host treatment procedures upon cell population growth kinetics seen subsequent to inoculation of hosts …

The problem with which this investigation is concerned is that of determining the steady-state and dynamic characteristics of the admittance of a metallic probe immersed in a laboratory plasma which has the low electron densities and low electron temperatures characteristic of the ionospheric plasma. The problem is separated into three related topics: the design and production of the laboratory plasma, the measurement of the steady-state properties of dc and very low frequency probe admittance, and the study of transient ion sheath effects on radio frequency probe admittance.

This study is concerned with discovering relationships between community power structures and economic growth. The economic growth in selected Northeast Texas counties and their major cities is compared with the power structures in each of these communities during the 1944 through 1968 period.
