The study herein described involved the detection of pyridine N-oxide reductase activity in cell-free extracts of E. coli 9723, the determination of co-factors necessary for the enzymatic process, a study of the optimum conditions for enzyme catalysis, and a general characterization of the enzyme.

The study reported herein concerns itself with the isolation of melaninless mutants of S. antibioticus, ATCC, 3723, and with the demonstration that at least one of the sites of mutation involves that of the enzyme, tyrosinase.

Performances of Fitrabras and the other Schubert operas have been very rare. Parts of Fierrabras were given in concert form in Vienna in 1853 and again in 1858. The first stage production was in Karlsruhe, February 9, 1897, but the music was revised for that performance by 0. Neitzel and the text by F. Mottl. The text was translated into French for a production in Brussels in 1926. A concert version was also heard in London in 1938. None of these performances, with the possible exception of the one in Brussels, was in the original version. It has always been assumed that the work could not be performed as it stands; at any rate, no one has ever tried. True, there are certain problems in production, especially in the rapid shift of scenes in the third act, but modern stage technique could undoubtedly conquer such difficulties easily.

D. H. Lawrence made the final break through the mask of Victorian prudery to gain a full conception of man and his role in the universe. His principal emphasis is on the restoration of man's conception of himself as animal, an animal capable of conceptualizing, but essentially animal all the same. In attempting to restore man to the mindless state of irrational animism, Lawrence did away with the conventional idea of man as the perfection of God's created universe. Lawrence did not conceive of man as being controller of the natural universe; he thought of man as being, like Mellors in Lady Chatterly's Lover, a warden who lives within natural order. He attacks vain intellectual sophistry of the scientific, industrial society and finds man to be a brute spirit caged by the conventions of his puny reason and his self-imposed social customs. Philosophically, he changes the emphasis from being to becoming.

Don Juan was Byron's effort to come to terms with the reality of his own environment, and he demanded the liberty to try to understand life and to present his conclusions without editorial or social oppression. It is an examination of the problem of appearance and reality; as a satire, the poem attacks appearances maintained by hypocrisy by placing them against the background of reality which is apparent to Byron.

It is the problem of this thesis to study recent commercial graphic arts materials and procedures, and to suggest some creative uses of them for college and university advertising art programs.

The problem of this study is the attempt to measure the religiosity of prison inmates and to determine if religiosity among prisoners may be more generally associated with certain types of crimes than with others such as homicide, assault, theft by violence, sex offenses, crimes against person and property, theft, embezzlement, and "other" offenses.

The primary objectives of this paper are to deal with Stravinsky's use of the trombone and to study the different methods of scoring for the instrument which he has employed in his works. In order to make this discussion more meaningful, the first chapter contains a brief history of the use and the development of the instrument from the fifteenth century up until 1900. In the second chapter Stravinsky's major works are divided into three periods, and each is individually discussed. The general characteristics common to the related major works are pointed out to provide an understanding of each period. The remainder of the paper is devoted to a study of Stravinsky's trombone scoring in three of his major works, one from each period. A concluding chapter summarizes his writing for the trombone as exemplified by these three works, and surveys the scoring for trombone in some of his other works.

The purpose of this study was to determine the availability of qualified industrial arts teachers in the twenty-four North Texas area school districts surveyed; and to ascertain the effects of industrial arts teacher availability upon the status of the industrial arts programs in the school districts surveyed.

The problem of investigating the possibilities of direct design transfer from plant to fabric and paper was divided into two parts. The first part is concerned with the exploration of the mechanics of the transfer. Invloved in this process are the technique of manipulating tools, of selecting suitable fabrics and paper, of determining chemicals that would facilitate the printing process and of experimenting with ways to preserve the finished design. The evaluation of the usability and durability of the finished print was based on a series of color fastness tests. The second part of this problem is concerned with the exploration of the design possibilities of the medium. The plants were tested and rated according to their visual attributes relative to the elements of design. Combinations of the successful plant prints were used to produce variations of pattern and texture. The results of the investigation were evaluated to determine the versatility of the medium as a design tool and the usefulness of the technique as a practical printing method

The purpose of the present study was to investigate the effect of heterogeneous grouping and homogeneous grouping in the language development of severely retarded students. A further purpose was to determine how beneficial either of the grouping procedures would be for this level of student.

The Piano Fantasy will be compared to Aaron Copland's other major piano works, the Piano Variations and Piano Sonata, to determine if he has retained his basic stylistic features, although he has employed serial principles more extensively in the piano fantasy than in the other two works and has passed through two different style periods, the "Abstract" (1929-1935) and the American "Folksong" (1934-1955).

The purposes of this survey were (1) to determine the nature of the case load of speech clinicians in Texas public school speech and hearing therapy programs, (2) to determine the type and condition of facilities in which the therapy described in item one above is being conducted, (3) to ascertain what the speech and hearing clinicians of the state believed to be essential for the effective practice of therapy, and (4) to find out what the clinicians believed to be special problems in their present facilities.

In his minor poems, Coleridge applies symbolic techniques to embellish the poetry and satisfy his spiritual needs. His symbolism allows for a release of pent-up emotions and transmits philosophical ideas in "capsule forms" rather than in historical prose, making them relate to the poetic appeal.

This symphony was composed for the purpose of communicating with a contemporary audience and not to please some unknown colleague or future generation. Therefore, experimentation with novel media or systems was rejected in favor of a more conventional approach.

"This thesis is a critical analysis of Tolkien's Elvish. This critical analysis is motivated in the same way as critiques of other aspects of literary art, such as plot, characterization, and structure. The latter are subject to critical evaluation precisely because they are a part of the writer's creative art. Elvish is also the product of the artist's creativity. The fact that Tolkien is a trained philologist and distinguished language scholar and has obviously lavished much time and effort on Elvish make this created language a valid area for analysis and criticism...in view of the extent of the available data, all that can be attempted here is a description of Elvish morphology and syntax in light of both the evidence and Tolkien's comments about it."--leaves 1-5

The purpose of this study was to determine whether the transfer of training would affect the achievement and retention scores of subjects learning selected tennis and badminton skills. This study was intended to establish the most beneficial teaching progression for tennis and badminton skills.
