The Hydraulics Revolution: Science And Technical Design Of Urban Water Supply In The Enlightenment., Edward Howard Winant

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the later half of the eighteenth century, French engineer-scientists revolutionized hydraulics. Funded by Royal research programs, these experimenters formulated predictive equations for flow velocities and quantities. Their results were published throughout Europe and America, causing a distinct change in the practice of designing aqueducts. Case studies of aquaeducts for Edinburgh in 1721 and New York City in 1838 detail the changes in the practice of hydraulic design. A comparison of these two examples illustrates the practical effects of the new hydraulic formulas. These are presented in chronological order, along with the details of the French research programs which so …

Formation And Structure Of C-8-Oxo/Aryl-Guanine Adducts In Dna., Wai-Ming Yau

Graduate Theses, Dissertations, and Problem Reports (ETD)

In biology and medicine, free radicals are now of intense interest because they have been shown to be involved in many different aspects of metabolism, ranging from oxygen consumption and autocatalysis to xenobiotic metabolism. Formation of free radicals in various systems may contribute to diseases and degenerative processes. Free radicals attack guanine in DNA to give 8-substituted guanine derivatives including C-8-oxo-2{dollar}\\sp\\prime{dollar}-deoxyguanosine (oG) and C-8-aryl guanine derivatives via hydroxy and aryl radicals, respectively. The work to be described herein resulted from studies of both adducts in relation to carcinogenesis and other pathogenesis. This dissertation is divided into five chapters. Chapter I …

Assessment Of Adolescent Quality Of Life: Development And Preliminary Validation Of A Self-Report Measure., Leslie E. Spieth

Graduate Theses, Dissertations, and Problem Reports (ETD)

Assessing the impact of chronic illness on child and adolescent functioning has become increasingly important as mortality rates associated with chronic illness have decreased and survival rates have increased. With improvements in prognosis, greater emphasis has been placed on the assessment of acute and residual dysfunction caused by chronic illnesses and their treatment. The multiple dimensions of functioning and well-being are commonly referred to as "quality of life" (QOL). The assessment of patient QOL provides an important outcome measure that complements the physiological outcome measures which are typically obtained. Patient reports of QOL are particularly important as the dysfunction caused …

Function Of An Autonomous Replication Sequence (Ars) In Coxiella Burnettii., Michelle Lynn Suhan

Graduate Theses, Dissertations, and Problem Reports (ETD)

A 5.8-kb EcoRI chromosomal fragment from Coxiella burnetii functions to initiate plasmid replication in Escherichia coli from a 403-bp minimal autonomous replication sequence (ars) (Chen, 1989). The minimal ars contains motifs found in bacterial origins, including two DnaA boxes, three AT-rich 21-mers, a transcriptional promoter leading rightwards, and potential IHF and FIS binding sites. Database comparisons of deduced amino acid sequences revealed that open reading frames adjacent to ars shared identity to genes often located near bacterial chromosomal origins. These were rpmH, rnpA, 9K, and 60K, in E. coli and Pseudomonas putida. To provide direct evidence for origin function in …

Vibration And Air-Resonance Stability Characteristics Of Helicopters Using Rotor-Body Dynamic Interaction., Senthilvel Vellaichamy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Vibration and Air-Resonance stability characteristics of helicopters in forward flight are studied using rotor-body dynamic interaction. The rotor blade and fuselage are considered as flexible structures. The blade undergoes flap, lag, and axial motions and twist about the elastic axis. The air loads are based on quasi-steady aerodynamics and linear inflow model. The governing equations are generated by expanding the generalized forces in the Hamiltonian as a first-order Taylor series. The zeroeth and n/rev. vibratory loads are predicted directly in the fixed frame. This is expected to be more accurate than the force or modal summation methods. The blade controls …

Acting As Agent Under A Financial Durable Power Of Attorney: An Unscripted Role, Carolyn L. Dessin

Akron Law Faculty Publications

The financial durable power of attorney, also known as a durable power of attorney for property management, is a creature of fairly recent origin. The estate planning bar created it to provide an effective alternative to guardianship or conservatorship proceedings when people become incompetent or incapacitated. Additionally, there was a sentiment that the wealthy had an effective way of dealing with potential disability by creating a funded inter vivos trust, and that such a device was not available to most individuals because of the prohibitive cost. Since its creation, the financial durable power of attorney has become an extremely popular …

Development Of Ultrasonic Techniques For Detection Of Internal Defects In Highway Concrete Structures., Allakbar Afshari

Graduate Theses, Dissertations, and Problem Reports (ETD)

The use of ultrasonic technique for detection of internal flaw and delamination in concrete structures is extremely difficult. In this research all traditional techniques were precisely studied and four new inspection techniques were developed which could be practically applied in testing concrete structures. The developed techniques are: (1) Detached Receiver Through Transmission technique(DRTT); (2) Direct testing of rebars in concrete structures; (3) Semi-Through Transmission Technique(STT); (4) Detached Receiver Pitch-Catch Technique(DRPC). All four of the developed techniques have low signal responses and resolution is critical. The detached receiver techniques have low responses because most of the signal is reflected at the …

A Study Of The Relationship Between School And District Office Linkage Patterns And The Implementation Status Of Key Middle Level Practices., Michael Lee Cunningham

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined the relationship between middle school principals' perceptions of the linkage patterns of their schools with the district office and the perceived degree of key middle level practices implementation by the school. To examine this relationship, the Survey of Middle Level Education was designed using measures related to the work of Fullan (1991) and Louis and Niles (1990) regarding change implementation in schools. The basis for the survey items related to communication and control linkage patterns were Likert's (1967) studies of organizational systems. This survey, which was sent to 600 middle school principals, was also designed to indicate …

The Process Of Home-Based Early Intervention: A Case Study Of A Family Educator In An Appalachian Community., Carole Ann Gnatuk

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many parents need support and intervention from the community to realize their essential role as their young children's primary teachers. Home visitation is one type of family support program that supplies that need. Although some measurable outcomes for children and parents in such programs have been noted, the dynamics of the action between the catalyst for development, the family educator, and family members cannot be measured quantitatively. Programming and funding decisions can be made with more accuracy if the rich human interactions are systematically narrated and thus appreciated as essential data. The research literature contains few qualitative studies focusing on …

Acoustic Emission Monitoring Of Concrete Structures Using Waveguides., Yidong Eddie He

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study is to develop acoustic waveguides for Acoustic Emission (A.E.) monitoring of concrete structures, in order to overcome the difficulty of high acoustic attenuation in concrete. Solid embedded waveguides, liquid-filled embedded waveguides and solid surface waveguides have been developed in this study. An analytical model of a waveguide with infinitely thick cladding was used to study the wave propagation in an embedded solid waveguide. The analysis revealed the guideline to construct an ideal embedded waveguide with efficient acoustic transmission, that is the existence of a real wavenumber. An embedded waveguide fulfilling the above criterion has not been constructed physically …
