Different Catalytic Mechanisms In Mammalian Selenocysteine- And Cysteine-Containing Methionine-R-Sulfoxide Reductases, Hwa-Young Kim, Vadim Gladyshev

Vadim Gladyshev Publications

Selenocysteine (Sec) is found in active sites of several oxidoreductases in which this residue is essential for catalytic activity. However, many selenoproteins have fully functional orthologs, wherein cysteine (Cys) occupies the position of Sec. The reason why some enzymes evolve into selenoproteins if the Cys versions may be sufficient is not understood. Among three mammalian methionine-R-sulfoxide reductases (MsrBs), MsrB1 is a Sec-containing protein, whereas MsrB2 and MsrB3 contain Cys in the active site, making these enzymes an excellent system for addressing the question of why Sec is used in biological systems. In this study, we found that residues, which are …

Ethical Guidelines In Genetics And Genomics. An Islamic Perspective, Aida I. Al-Aqeel

Saudi Medical Journal

We are at a time of unprecedented increase in knowledge of rapidly changing technology. Such biotechnology especially when it involves human subjects raises complex ethical, legal, social and religious issues. A World Health Organization expert consultation concluded that "genetics advances will only be acceptable if their application is carried out ethically, with due regard to autonomy, justice, education and the beliefs and resources of each nation and community." Public health authorities are increasingly concerned by the high rate of births with genetic disorders especially in developing countries where Muslims are a majority. Therefore, it is imperative to scrutinize the available …

Evaluation Of Mechanical Properties Of Recycled Aggregate Concrete, Sajjad Ali Khan

Masters Theses

The maintenance and repair work in the civil engineering infrastructures develops the production of huge wastes which causes the growth of waste piles, additional costs in construction projects and some environmental problems. If this waste is recycled and used again in construction projects, it will help to overcome the problems discussed earlier. Moreover, if natural aggregates are supplemented by recycled aggregate, it will preserve the natural resources and also put a pause in the deterioration of natural landscape.

This thesis addresses the importance of using recycled aggregate in concrete structures. Its practical feasibility in construction projects is studied in light …

Evaluation Of Mechanical Properties Of Self-Consolidating Concrete, Bhusan Basnet

Masters Theses

The concept of Self-Consolidating Concrete is a fresh and rapidly ramping technology in USA, but in some other continents such as Japan and Europe it is in fully fledged stage. The development of this technology has a high potential to economize construction minimizing labor, scheduled time and equipment eliminating consolidation process. In USA, construction professionals are reluctant to its in-effect application because of lack of deliberate and methodological steps for production and applications. The lack of study of its durability characteristics and confusion in design and production process are seems to be vital factors hindering full scale production and application …

Determination Of Stiffness Matrix Of Tapered Roller Bearings For Vibration Models, Jeeva Kumar

Masters Theses

The stiffness matrix of tapered roller bearings under radial and axial load conditions was evaluated using an analytical model and an experimental approach. An experimental test system was designed and manufactured to determine the radial stiffness of the bearing under combined axial and radial load conditions. A second fixture was designed to measure the stiffness of the bearing under pure axial load conditions. The stiffness coefficients determined have been compared with those obtained from the analytical model, OEM (Original Equipment Manufacturer) data and ABAQUS model (finite element analysis software).

Paper Substrates For Electronic Printing, Laura K. Wood

Masters Theses

Printed Radio Frequency Identification (RFID) labels utilize conductive inks to provide the means for wireless flow of electronic signals. An RFID label is an identification label with an integrated circuit and antenna that transmits data via radio waves to a reader, which sends the data to a computer for processing. RFID labels allow manufacturers and retailers to accurately track their inventory more efficiently than previously possible with bar codes. However, etched metal RFID labels are too expensive for widespread implementation. The key to reducing the cost of RFID technology is replacing etched metal tags with tags printed with conducting ink. …

A K-Epsilon Extension For Wall-Bounded Flows On The Broadband Aeroacoustic System Simulator, David González

Masters Theses

The turbulence modeling capabilities of the Broadband Aeroacoustic System Simulator (BASS), an experimental code developed at NASA Glenn Research Center, have been extended to include wall-bounded flow capabilities. This was done by first validating the code's viscous solving routines by comparing numerical solutions to known, simple analytic solutions. Finally, the dynamics of the wall shear flows were accounted for with the use of wall-damping functions incorporated into the turbulence model. The results for both viscous and turbulence routines agree well with published data.

Perception And Reality: An Examination Of American Print Advertising, Angela Rose Ryczkowski

College of Graduate Studies: Theses & Dissertations

I contend current American print advertising relies on the objectification of the body, both male and female, in conjunction with the use of utopian ideals to sell products. The nature of the print ad and mass media is such that they gratuitously inform our cultures ideas on gender and normalcy. By depicting unrealistic images of normalcy and unattainable representations of beauty, advertising not only creates consumer anxiety to purchase products beyond economic means, but also to manipulate our bodies unnaturally, and it creates tension in relations between genders. As a Graphic Designer, I strive to not only reverse this process …

Controllability, Observability And Realizability, Inna N. Smith

College of Graduate Studies: Theses & Dissertations

In this research project, we analyze three important concepts of the control theory, including controllability, observability and realizability. In particular, we analyze the theory of and solutions to linear time systems, continuous and discrete time systems, time-varying systems, and first-order matrix Sylvester systems. Examples and sample computed calculations are provided for both uncontrolled and controlled systems. We also develop a new method for computing the approximate values of matrix exponentials, and use this to estimate solutions to initial value problems.

A search for lepton-flavor-violating interactions ep → μX and ep → τX has been performed with the ZEUS detector using the entire HERA I data sample, corresponding to an integrated luminosity of 130 pb-1. The data were taken at center-of-mass energies, √s, of 300 and 318 GeV. No evidence of lepton-flavor violation was found, and constraints were derived on leptoquarks (LQs) that could mediate such interactions. For LQ masses below √s, limits were set on λeq1 √β ℓq, where λeq1 is the coupling of the LQ to an electron and a first-generation quark q1, and βℓq is the branching ratio …

Dynamic Determinants Of Incisal Display, Shawn Paul Pesh

Loma Linda University Electronic Theses, Dissertations & Projects

The principal objective of this study was to use computer aided design (CAD) to better illustrate and quantify the relationship of mandibular arch depth, mandibular arch width, overbite, and overjet in the presence of mandibular dental crowding. To date, there has been no research examining how changes in the mandibular arch limit the orthodontist's ability to control overbite and overjet. Understanding how to effectively manage overbite and overjet are crucial to the clinician's ability to manipulate incisal display. Polyvinyl siloxane impressions of both maxillary and mandibular arches of a Caucasian patient were taken and used to pour dental stone models. …

Performance Evaluation Models For Strategic Decision-Making: Towards A Hybrid Model, Geraldina Villalobos Quezada

Dissertations

Performance management systems serve strategic, administrative, and developmental purposes; therefore, their role in an organization cannot be overestimated. As a function of this strategic role, different evaluation models have been developed and implemented by organizations: BSC, CIPP, TQM, Six Sigma, and AOP.

Following a review of current evaluation theory and practice models that focus on improving strategic decision-making in organizations, four research questions were developed that sought to identify the interrelationships, evaluation components, evaluation indicators, data collected to support the evaluation,evaluation implementation protocols, quantitative and qualitative analyses, outcomes, and critical factors of the BSC and CIPP models.

Preliminary Design Approach For Prosthetic Ankle Joints Using Compliant Mechanisms, Jason Matthew Wiersdorf

Theses and Dissertations

The objective of this thesis is to develop design approaches and models for prosthetic ankle joints using kinematic models of the human ankle and compliant mechanisms technology. Compliant mechanisms offer several potential design advantages over traditional rigid-body designs including high reliability and low cost. These design advantages are ideal for use in prosthetics. Some prosthetic ankle/foot systems currently on the market have multiple degrees of freedom yet are expensive. Additionally, even though these systems have multiple degrees of freedom, none of them are designed after the actual movements of the biological ankle. In this thesis a two, single degree-of-freedom hinge …

Regulation By Adaptive Management--Is It Possible?, J.B. Ruhl

Vanderbilt Law School Faculty Publications

Today's voluminous literature on adaptive management traces its roots to Professor C.S. Holling's seminal work, Adaptive Environmental Assessment and Management. Although almost thirty years have passed since he and his colleagues first described the adaptive management methodology, no work on the topic has improved on their core theory. Its essence is an iterative, incremental decisionmaking process built around a continuous process of monitoring the effects of decisions and adjusting decisions accordingly. It is in other words, far more suited to the needs of future regulatory challenges than is prescriptive regulation. My focus, however, is not on what adaptive management should …

Automotive Service Technology Intersectional Skills Proficiency Assessment, David L. Macquarrie

Dissertations

This dissertation focused on the creation and validation of a criterion referenced credentialing assessment of automotive service technicians' intersectional skills (ASTIS) proficiency. These intersectional skills are prerequisite and common to multiple job level tasks that an automotive service technician (AST) performs on the job. An assessment of the ASTIS was created to aid automotive technician employers in the evaluation of hiring prospective technician employees and is not duplicated by current certifications (e.g. ASE) as they do not uniquely assess these skills.

This dissertation focused on the ASTIS skills and the information an employer can obtain pertaining to a prospective employee's …

Joseph Smith And The Making Of A Global Religion, Jan Shipps

BYU Studies

In regard to the other “worlds” of the first Mormon prophet, Joseph Smith was certainly “in that world and of it.” He was clearly in attendance “in his own time;” he attempted to recover past worlds; he was and is present in his own and in the personal worlds of others; and he challenged the theological world of his day.

Workfare In Toronto: More Of The Same?, Ernie Lightman, Andrew Mitchell, Dean Herd

The Journal of Sociology & Social Welfare

This paper uses a recent survey of welfare leavers in Toronto to examine Workfare, a uniquely American initiative introduced into Canada, with its different welfare state history and traditions. When classic American workfare was imported by an enthusiastic government in Ontario, its application led to employment outcomes remarkably similar to those in the US (reduced caseloads, insecure and contingent employment, high recidivism). Yet, Canada's earlier commitment to community and collective responsibility have not been entirely subsumed below the overarching American umbrella. Welfare programs in Canada-specifically, workfare-reflect both the difficulties of maintaining great difference, and also the possibilities of following an …
