Mechanisms for fatigue and wear of polysilicon structural thinfilms

Description: Fatigue and wear in micron-scale polysilicon structural films can severely impact the reliability of microelectromechanical systems (MEMS). Despite studies on fatigue and wear behavior of these films, there is still an on-going debate regarding the precise physical mechanisms for these two important failure modes. Although macro-scale silicon does not fatigue, this phenomenon is observed in micron-scale silicon. It is shown that for polysilicon devices fabricated in the MUMPs foundry and SUMMiT… more

Study of Bs mixing at the CDFII experiment with a newly developed opposite side b-flavour tagging algorithm using kaons

Description: This thesis describes the development, calibration and performance evaluation of an Opposite-side b flavor tagger using K mesons at a p{bar p} hadron collider. In particular, this work is performed using data collected by the Collider Detector at Fermilab (CDF) during the Run II of the Tevatron hadron collider running at {radical}s = 1.96 TeV. b flavor tagging consists of the determination of the flavor of the b quark contained within a hadron. This information is vital to perform any time-depe… more

The Effects of District Expenditure Per Pupil and Low Socio-Economic Status on the Grade 10, 2000 and 2002 Disaggregated Student Performance Scores on the TAAS

Description: Educators can no longer simply look at student totals to distribute instructional dollars. Databased decision-making must be instituted to overcome achievement gaps between white and non-white students. In low-socioeconomic (SES) settings, districts must increase expenditure per pupil (EPP) as low-SES rates rise for all students as district administrators must be in a position to show product rather than process. It was attempted to determine if a positive or negative relationship existed betwe… more

Dimension spectrum and graph directed Markov systems.

Description: In this dissertation we study graph directed Markov systems (GDMS) and limit sets associated with these systems. Given a GDMS S, by the Hausdorff dimension spectrum of S we mean the set of all positive real numbers which are the Hausdorff dimension of the limit set generated by a subsystem of S. We say that S has full Hausdorff dimension spectrum (full HD spectrum), if the dimension spectrum is the interval [0, h], where h is the Hausdorff dimension of the limit set of S. We give necessary cond… more

A study of continuing bonds and their impact on life attitudes in parents of murdered children.

Description: For most of the past century, the positive outcome of grief in the West was characterized as the relinquishment of the bond to the deceased. Phrases such as "let go", "move on", and "get over it" were, and continue to be, common to the language of this pursuit. This 'breaking bonds' perspective does not take into account other means of grief resolution, nor does it consider historical or cultural findings. Consequently, reports of bereaved parents who indicate resolution of grief yet maintain a… more

The Long Chorale Preludes of J. S. Bach (1685-1750): Study of Accompaniments together with Three Recitals of Selected Works by Dietrich Buxtehude (1637-1707), J. S. Bach, Louis Vierne (1870-1937), and Others

Description: Johann Sebastian Bach's chorale preludes are varied and artistic not only in the treatment of chorale melodies, but also in the accompaniments of those chorale melodies. This study examines the accompaniments of Bach's long chorale preludes, focusing on identifying the various types and the characteristics that make them unique. This study investigates the two broad categories of accompaniments depending on whether the motives are chorale-derived or independent of the chorale. While the chora… more

Theory in Practice: Constructivism and the Technology of Instruction in an Authentic Project-based Computer Class

Description: While literature in areas of constructivism learning theory, use of computer technology in education, and the implementation of project-based learning in the classroom have received widespread attention, there is no reported research that specifically examines the effectiveness of using a project-based learning model for computer technology instruction for pre-service teachers' programs in general, and in art education in particular. Thus, the research problem was to examine through pre- and p… more

Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification

Description: The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate w… more

Identification and characterization of an incomplete root hair elongation (IRE)-like gene in Medicago truncatula (L.) root nodules.

Description: Cloning and molecular characterization of new genes constitutes a useful approach in studying the symbiotic interactions between the model plant Medicago truncatula and Synorhizobium meliloti. Large numbers of expressed sequence tags (ESTs) available for Medicago truncatula, along with numerous cDNA, oligonucleotides, and Affimetrix DNA microarray chips, represent useful tools for gene discovery. In an attempt to identify a new gene that might be involved in the process of nodulation in Medica… more

Supercritical Silylation and Stability of Silyl Groups

Description: Methylsilsesquioxane (MSQ) and organosilicate glass (OSG) are the materials under this study because they exhibit the dielectric constant values necessary for future IC technology requirements. Obtaining a low-k dielectric value is critical for the IC industry in order to cope time delay and cross talking issues. These materials exhibit attractive dielectric value, but there are problems replacing conventional SiO2, because of their chemical, mechanical and electrical instability after plasma p… more

Intangible Qualities of Rare Books: Toward a Decision-Making Framework for Preservation Management in Rare Book Collections, Based Upon the Concept of the Book as Object

Description: For rare book collections, a considerable challenge is involved in evaluating collection materials in terms of their inherent value, which includes the textual and intangible information the materials provide for the collection's users. Preservation management in rare book collections is a complex and costly process. As digitization and other technological advances in surrogate technology have provided new forms representation, new dilemmas in weighing the rare book's inherently valuable charac… more

A morphological study of the avian (Gallus domesticus) ductus arteriosi during hatching.

Description: The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences bet… more

Democratic Pantheism in the Political Theory of Alexis de Tocqueville

Description: According to Alexis de Tocqueville, humanity is entering a new age of political and social equality, a new epoch in which the human race has no historical example or experience. As a result, he holds humanity's future will be largely determined by the political and moral choices made in this transitional time. For Tocqueville, the new egalitarian era is a forgone conclusion, but for him, the pressing question is whether humanity will choose a future in which it enchains itself to new forms of … more
