Rapid receptive field (RF) reorganization of somatosensory neurons in the cat dorsal column nuclei (DCN) was studied using electrophysiological and histological methods. Soon after denervation of the peripheral RF by lidocaine injection, every DCN neuron tested exhibited a reorganized RF.

This study of semigroups discusses groups, ideals, relations on semigroups, and relation classes in semigroups. Each topic is covered in some detail; but since this is a general study of semigroups, no topic dominates the paper. The definitions, theorems, and corollaries are supplied by Dr. August Lau, and all proofs are the work of Ms. Bryant.

For this investigation two types of observations used: Texas's private and public institutions that provide residential treatment to children severely handicapped and children served by those facilities. The overall result showed that the distance between the child's home and the treatment facility is great for public institutions than for private.

The implications of sociobiology as presented in Wilson's Sociobiology: The New Synthesis are examined to determine to what extent 1) sociobiology can subsume sociology; 2) sociobiology is antithetical to sociology; 3) sociobiology reflects a movement within sociology. Basic assumptions of sociobiology pertinent to sociology--degree of determinism, existence of human universals, and definitions of society, culture, and human nature--are scrutinized alongside Wilson's view of sociology as a scientific discipline. The thesis explores weaknesses of both sociology and sociobiology and concludes that sociobiology, in ignoring culture as a source of behavioral motivation, is limited in reducing the sociological perspective to a biological one. Although the two disciplines have antithetical foundations, sociology has already begun to incorporate selected aspects of the sociobiological perspective.

The problem with which this study is concerned is that of analyzing the implementation of the stated purposes of analyzing the implementation of the stated purposes of Lon Morris College of Jacksonville, Texas from 1847 to 1973. Histories and Journals of the period, records and publications of the school and other institutions, and oral interviews of persons involved in its development provide data for the study. As a historical analysis, the study is divided according to successive periods in the school's development.

The problem of this study was the development of a model for the certification requirements for vocational office education teacher coordinators in the United States. The data for this study were obtained from library research, documents provided by the state directors of vocational education and state departments of education, 62 questionnaires returned from randomly selected businesses and office education educators, and 735 questionnaires returned from randomly selected employed vocational office education teacher-coordinators.

The problem with which this study is concerned is that of constructing a system of selection and human resource development for small retailers of apparel and accessories. The study has a twofold purpose. The first is to determine the extent to which organized selection and training practices exist in small apparel and accessory retailing establishments, and the general attitude which small retailers of apparel and accessories express toward the value of selection and training functions. The second is to construct a practical system which can be used in small apparel and accessory retailing establishments.

Electron densities and collision frequencies were obtained on a number of gases in a dc discharge at low pressures (0.70-2mm of Hg). These measurements were performed by microwave probing of a filament of the dc discharge placed coaxially in a resonant cavity operating in a TM010 mode. the equipment and techniques for making the microwave measurements employing the resonant cavity are described.

This study had three main purposes. The first was to determine the perceptions of public school administrators toward desirability and toward feasibility of accountability items. The second was to determine the perceptions of public school teachers toward desirability and toward feasibility of accountability items. The third was to compare the perceptions of administrators with those of teachers and to indicate areas where they seemed to be in agreement or disagreement.

A 5.1 kbEcoR I fragment from Pseudomonas putida TOL plsmid pDKR1, carrying the xylE and xylL genes, was inserted into pBR 325 and transformed into E. coli. The xylE region, coding for catechol 2,3-dioxygenase, was subjected to Maxam-Gilbert sequencing reactions.

All of Mahler's works may be divided into four distinct chronological groups, referred to as "symphonic cycles." Motives and themes from the songs within each symphonic cycle were quoted in symphonies in the same cycle. This system of self reference was unique to Mahler, although earlier composers such as Schubert and Wagner set precedents for some of the techniques used by Mahler. The quotations in the early periods appeared only on the surface and did not blend well with their surroundings, but as time progressed Mahler developed the ability to combine the seemingly incompatible elements more smoothly. Mahler's early fascination with distant sounds was also a factor in his use of quotations. The appendix contains a catalog of 100 quotations.

Muscle, hypodermis and gastrointestinal epithelium from adult female Ascaris lumricoides var. summ were found to contain serotonin based upon glyoxylic acid induced histofluorescence and indirect immunolabeling with an anti-serotonin monoclonal antibody conjugated to protein A-colloidal gold.

Cell cultures were examined for percentage of fragile sites seen in straight-stained, Q-stained and reverse fluorescent-stained preparations. In all cases, percentage of fragile site expression was decreased when compared to straight-stained preparations. However, fragile sites seen in Q- and RF-stain could be identified as on X chromosomes.

This study is about the development of a curriculum guide which projects flexibility, continuity, sequential framework, and to a certain extent, uniformity, around which each teacher may build an art program that will best meet the students' needs. Areas pertinent to developing the curriculum guide are presented in light of literature in this field. The guide may be used to facilitate the teaching of art in recognizing and understanding artistic development that is essential in bringing to fruition the inherent individual ability of all the Junior High Catholic School students.

This study reports on a variety of experimental and theoretical studies conducted in ZnSe, CdTe, and in semiconductor-doped glasses. The transient picosecond degenerate four-wave mixing (DFWM) experiments performed in these II-VI direct-gap semiconductors are part of our efforts to understand the picosecond dynamics of the free-carriers generated via two and three-photon absorption.

Histone proteins were examined during development in the meiotic elongate and a genetically close line N6HT. Histones were also extracted from an F1 (el x N6Ht). Comparisonc beteen the histone samples from each line of N6HT and elongate, and the F1 for leaf, root, and stem were inconclusive. A tassel sample form elongate exhibited a markedly slower migrating band that was not present in N6HT. The histone profiles of elongate and N6HT also differed. Each line N6HT and elongate exhibited three protein bands in the H1 region. Maize histone samples have been shown to exhibit four major H1 bands. The possibility exists that an H1 protein altered in its molecular weight and possibly in its interaction with the chromosome is present in elongate.

Heinrich Zille (1858-1929), an artist whose creative vision was concentrated on Berlin's working class , portrayed urban life with devastating accuracy and earthy humor. His direct and often crude rendering linked his drawing and prints with other artists who avoided sentimentality and idealization in their works.

The problem addressed in this paper was the appropriateness of fiber, especially in the form of fabric, as an art medium. Relevant statements by crafts makers, philosophers, art critics, and artists were investigated along with historical and contemporary art and craft works.

The purpose of this dissertation is to analyze the six special military units which were authorized and created by the War Department under the direction of Secretary of War Edwin M. Stanton. In relating the military history of such special units the study determines what contributions and significance they made to the Union war effort.
