Although cultures of A. calcoaceticus BD413 are naturally competent at all growth phases, genetic markers can only be successfully transformed by DNA from the genus Acinetobacter. Transformation frequencies of nearly 1.2% were obtained with pcaA mutants were incubated in liquid culture with wild-type DNA.

This study concerns the contributions of Major Albert Sobey and his educational leadership during the development of the engineering cooperative education program that became the foundation for the General Motors Institute in Flint, Michigan. This study also examines Albert Sobey's contributions to the emergence of industrial cooperative education in America over the past seventy years.

The purpose of this study was to investigate the role of background knowledge on Thai teachers-college students' reading comprehension in relation to topic familiarity, reading ability in English as a Foreign Language, and the amount of time required for reading familiar and unfamiliar passages.

A leukemia Differentiation Factor (DF), that induced differentiation of rat leukemia MIA C51 cells, was isolated from endotoxin-stimulated rat lung conditioned media.

Brain-reactive antibodies (BRA) increase in frequency with age in several mammalian species and may be involved in the pathogenesis of age-related dementia. In this experiment, the molecular specificity of BRA in mouse sera was determined using an immunoblot assay, and the relationship of BRA to longevity was studied by comparing the rate of formation of specific BRAs in diet restricted C57BL/6NNia, B6D2F1/NNia, and DBA/2NNia, genotypes which differ markedly in life-span.

The study ascertained elementary school teachers' and supervisors' views about their role in the implementation of Sankofa (Go back and retrieve) in school music. Sankofa mandates the integration of distinctive Ghanian traditional values and practices with Western educational concepts in the school curriculum. In music, it calls for the fusion of multi-ethnic musics of Ghana with Western musical concepts in public school music instruction. Some concerns expressed by Ghanian music educators regarding teachers' negative attitudes toward Sankofa in public school music had prompted the study.

This work includes two different areas of research. Both areas are related to the combustion of the binder-enhanced densified refuse derived fuel (bdRDF) with high sulfur coal and examining trace elements. The first area of this work involved studying the trace metals in the combustion gas of bdRDF/coal blend and the effect of the binder, CA(OH)2, on reducing the trace elements emissions. The second area of work involved studying the trace elements in the fly ash and the effect of the dRDF and the binder of trace metals.

In this study the mouse tumor necrosis factor-alpha (TNF-α) was prepared by stimulating macrophage cell line RAW 264.7 with lipopoly-saccharide (LPS) obtained from Escheria coli strain 055:B5.

In this study a library of EcoRI fragments encompassing the entire TOL region of the Pseudomonas putida TOL plasmid pDK1 was constructed in the Escheria coli cloning vector pBR325.

Clinical evidence has demonstrated that the anxiolytic effects produced by the selective 5-hydroxytryptamine1A (5-HT1A) receptor agonist, gepirone, increase progressively over one to three weeks of treatment.

The purpose of this study was to determine the personal reading interests of students in the third, fourth, and fifth grades and to determine if advances in technology in the past twenty years have changed their reading interests.

Research provides biological and ecological information on Hydrilla Verticillata (L. f.) Royle in Gatun Lake, Panama for an ongoing management program of aquatic weeds in the Panama Canal. Morphological and genetic variation, standing crop and life cycle were determined.

This study investigated the relationship between visual cues in art reproductions, simple linguistic time vocabulary and children's temporal understandings. During interview sessions, 33 third-grade students attending two suburban schools were asked to place three art postcard reproductions sets in chronological order. Interviews were recorded, transcribed, and coded for analysis. Linguistic references used to represent historical time and visual cues within the art postcards which caused students to place art works in a particular time sequence were documented.

This study examines the history of the cadenza, as well as the fundamental elements of a good cadenza. This paper is intended to help the modern trombonist learn to create appropriate, original cadenzas for classical trombone concerti. Both historical and modern writing,as well as extant classical cadenzas are used as a guide.

The problem of this study was to determine if principals' freedom to make the decisions for their respective buildings affects the job satisfaction of principals.

The purpose of this study was to determine if certain student demographics and measures of previous high school academic achievement could differentiate between students who are successful in remedial and college level English and algebra courses and students who are unsuccessful in those courses.

The problem with which this study is concerned is the possibility of increasing mathematical problem-solving knowledge of elementary school teachers and the acceptance of computers in instruction through the use of computers and student-oriented computer software.

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.

The purpose of the present study was to determine: (1) that dental office personnel would be exposed to more toxic chemicals in the workplace than the non-dental office controls; (2) that exposure should lead to a reduction in the efficiency of the immune system in the individuals in the dental office; and (3) the immunological deficit should manifest itself in psychological and/or physiological pathology as measured on the Profile of Mood States (POMS) and Bender Gestalt.

Songs of the Wind is a five-movement composition for reader, chamber choir, and chamber orchestra. The work is approximately twenty-five minutes in duration. The title describes the programmatic nature of the piece, which depicts an animistic ritual invoking the wind as a deity. The texts are drawn from translations of American Indian poetry as well as original poems by the American Indian scholar Hartley Alexander.

The purpose of this research was to reveal the morphological and cytological characteristics of Azotobacter vinelandii cells cultured in dialyzed soil medium. Culture samples taken at two, four, eight, sixteen and thirty-two days were prepared and examined with the electron microscope. Comparisons of the morphology of Azotobacter vinelandii grown in dialyzed soil medium with those grown in Burk's nitrogen-free, chemically-defined medium were done.

Constellations is a single movement work that explores the color between acoustic instruments and computer generated sounds. It is scored for four flutes (two doubling on piccolos), two oboes, two bassoons, eight B-flat clarinets, two bass B-flat clarinets; two alto saxophones, tenor saxophone, baritone saxophone; four trumpets in B-flat, four horns in F; three trombones, bass trombone; two tubas;piano; six percussionists; and contrabass. The duration of the work is nine minutes and twenty-eight seconds. Mapping of stellar constellations provide the primary material for all pitch and harmonic progressions throughout the work. Software synthesis and digital sampling techniques coalesce to produce the computer music on tape.

By presenting the auditor as a unifying principle that links Browning's earliest works to his dramatic monologues, this dissertation enhances the importance of the ever-ignored experimental works in developing the dramatic monologue technique. An exploration of the emergence and development of the auditor has an additional, but never ancillary, effect of proclaiming the originality and inventiveness of Browning's dramatic technique.

Chromosomal DNA of A. vinelandii thought to carry multiple gene copies was examined in efforts to visualize its chromosomal structure using electron microscopy. The chromosomal DNA of A. vinelandii may have multiple circular genomic units carrying multiple copies of genes. Three possible branch construction schemes and their replication modes are postulated in this study.
