Citrate Binding To The Membrane Protein Proteorhodopsin, Farhana F. Syed

Chemistry - Dissertations

Proteorhodopsin (pR) is an intrinsic membrane protein with an important role in solar-energy storage of the biosphere. Earlier work in our lab has shown that polyhistidine-tagged pR can be purified by means of selective precipitation with citrate under specific conditions, as can a number of mutants based on this His₆-tagged pR. Purification of a heterologously-expressed trans-membrane protein by a simple salt such as citrate is novel. However, such a phenomenon leads to several questions: How does citrate cause pR precipitation? Does the polyhistidine-tag assist in such a precipitation? Is this precipitation pH-specific? Does citrate affect the function of …

A Conceptual Framework And Simulation Modeling Of Engineering Change Management In A Collaborative Environment, Krishna Rao Reddi

Mechanical and Aerospace Engineering - Dissertations

Engineering Change Management (ECM) in a collaborative environment is a complex process and is crucial to the Original Equipment Manufacturer (OEM) to ensure low product development time and cost. In this thesis, the ECM in a collaborative environment has been studied and a conceptual framework to support the process is presented. New Product Development (NPD) and ECM processes have been modeled and simulated to study the associated process dynamics.

An extensive review of the literature indicated that the research on ECM in a collaborative environment is very limited. The review also highlighted that, (i) the ECM frameworks from past research …

Student Engagement In New Zealand’S Universities, Ali Radloff

Australasian Survey of Student Engagement (AUSSE)

Although the numbers of students entering bachelor level study in New Zealand is growing and is high relative to OECD averages, the number of students leaving with a qualification is low compared to many other countries. Data from the Ministry of Education show that completion rates are relatively low, particularly among certain groups of students. Around one-third of students who began a bachelor degree in 2002 had not completed the degree, or a degree at the same or a higher level, eight years after starting. Completion rates are higher among Asian New Zealand students, but much lower among Maori and …

Hacking, Theft, And Corporate Negligence: Making The Case For Mandatory Encryption Of Personal Information, Stephen J. Rancourt

Texas Wesleyan Law Review

Information is being created at an astonishing rate, and the electronic storage of personal data is at the forefront of this growth. Social security numbers, home and email addresses, and financial records are almost universally stored electronically, whether on internal servers, hard drives, or portable devices, such as flash drives and diskettes. The ubiquity of this information has undoubtedly benefitted commerce, but it has not come without drawbacks. As recent evidence suggests, personal information is increasingly vulnerable to hacking and other forms of theft, putting the consumer at serious risk of identity theft and misuse of their personal information. The …

Mechanical Stretch And Shear Flow Induced Reorganization And Recruitment Of Fibronectin In Fibroblasts, Robert L. Steward, Chao Min Cheng, Jonathan D. Ye, Robert M. Bellin, Philip R. Leduc

Biology Department Faculty Scholarship

It was our objective to study the role of mechanical stimulation on fibronectin (FN) reorganization and recruitment by exposing fibroblasts to shear fluid flow and equibiaxial stretch. Mechanical stimulation was also combined with a Rho inhibitor to probe their coupled effects on FN. Mechanically stimulated cells revealed a localization of FN around the cell periphery as well as an increase in FN fibril formation. Mechanical stimulation coupled with chemical stimulation also revealed an increase in FN fibrils around the cell periphery. Complimentary to this, fibroblasts exposed to fluid shear stress structurally rearranged pre-coated surface FN, but unstimulated and stretched cells …

Quasi‐Hidden Markov Model And Its Applications In Cluster Analysis Of Earthquake Catalogs, Zhengxiao Wu

Research Collection School of Economics

We identify a broad class of models, quasi-hidden Markov models (QHMMs), which include hidden Markov models (HMMs) as special cases. Applying the QHMM framework, this paper studies how an earthquake cluster propagates statistically. Two QHMMs are used to describe two different propagating patterns. The “mother-and-kids” model regards the first shock in an earthquake cluster as “mother” and the aftershocks as “kids,” which occur in a neighborhood centered by the mother. In the “domino” model, however, the next aftershock strikes in a neighborhood centered by the most recent previous earthquake in the cluster, and therefore aftershocks act like dominoes. As the …

Severance V. Your Texas Public Beach, Ellis Pickett

Texas Wesleyan Law Review

Coastlines, like riverbanks, are dynamic. They continually move, usually imperceptibly, but in storm events they can move a great distance. This movement affects both private and public property rights. The State owns "submerged lands," wherever they happen to be at the time.' In legal documents in Texas, terms such as "along the river" and "with the meanders of the river" describe property boundaries. The difference between Gulf of Mexico and riverfront property is gulf beaches are open to the public, whereas the sand along rivers is private property. There is no Open Beaches Act for rivers. Owners of beachfront property …

Clean Air Act Mayhem: Epa’S Tailoring Rule Stitches Greenhouse Gas Emissions Into The Wrong Regulatory Fitting, Teal Jordan White

Texas Wesleyan Law Review

Regardless of whether you believe that human activities cause or contribute to global warming, regulatory action seeking to mitigate the future consequences of climate change will impact the lives of every American. On January 2, 2011, U.S. Environmental Protection Agency ("EPA") regulation of greenhouse gas emissions from stationary sources took effect. The EPA rule implementing this regulation is the conclusion, for the time being, of a sequence of recent judicial and administrative activities comparable to a regulatory domino effect. The Supreme Court started the cascade of regulation in Massachusetts v. EPA, in which the Court held that the EPA has …

Highly Porous Silica Network Prepared From Sodium Metasilicate, R E. Essien, O A. Olaniyi, L A. Adams, R O. Shaibu

Journal of Metals, Materials and Minerals

Porous silica network was prepared from sodium metasilicate (Na2SiO3) at room temperature (27C) using hydrochloric acid (HCl) as catalyst through the sol-gel method. The gel was dried at 120C for 1 day and calcined at 800C for 3 hours and the material obtained characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The results showed the formation of amorphous silica particles of average sizes 598 nm with ordered porous network of pore sizes ranging from 0.18-0.91 ?m. This synthetic route uses sodium metasilicate as commercial precursor without pore forming templates which could be useful …

State-Based Techniques For Designing, Verifying And Debugging Message Passing Systems, Rajaa Khaled Alqudah

Electrical Engineering and Computer Science - Dissertations

Message passing systems support the applications of concurrent events, where independent or semi-independent events occur simultaneously in a nondeterministic fashion. The nature of independence, random interactions and concurrency made the code development of such applications complicated and error-prone. Conventional code development environments or IDEs, such as Microsoft Visual Studio, provide little programming support in this regard. Furthermore, ensuring the correctness of a message passing system is a challenge. Typically, it is important to guarantee that a system meets its desired specifications along its construction process. Model checking is one of the techniques used in software verification which has proven to …

The Extended Preferred Ordering Theorem For Radar Tracking Using The Extended Kalman Filter, Donald Leskiw

Electrical Engineering and Computer Science - Dissertations

A certain problem in nonlinear estimation exists in radar tracking. Usually radar detections provide instantaneous position measurements in radar (polar) coordinates at discrete times, while tracks (estimated positions and motions over continuous time) are determined in rectangular coordinates; and the linear Kalman filter (LKF) is used as the estimator. Less common, the LKF is used to determine the tracks in radar coordinates, which are then converted into rectangular coordinates. Rarely is the extended Kalman filter (EKF) used, where the tracks are directly determined in rectangular coordinates from the radar detections via a local linearization. And so most radar tracks tend …

Effects Of Calcium Addition On Structure And Bioavailability Of Soil Organic Matter, Ankit Balaria

Civil and Environmental Engineering - Dissertations

The northeastern USA has a long history of acid rain, which has impacted soil fertility and raised concerns about the sustainability of the forests in the region. To facilitate recovery of these forests, calcium addition, in the form of wollastonite, was evaluated as a remedial tool at Hubbard Brook Experimental Forests in New Hampshire, USA. In order to study the effects of these amendments on soil organic matter and soil microbes, I characterized the structural chemistry of soil organic matter (SOM) and its hot-water extractable organic matter (HWEOM) fraction for Hubbard Brook soils and studied the changes in the structure …

Synthesis And Biosynthesis Of Polyketide Natural Products, Atahualpa Pinto

Chemistry - Dissertations

Traditionally separate disciplines of a large and broad chemical spectrum, synthetic organic chemistry and biochemistry have found in the last two decades a fertile common ground in the area pertaining to the biosynthesis of natural products. Both disciplines remain indispensable in providing unique solutions on numerous questions populating the field. Our contributions to this interdisciplinary pursuit have been confined to the biosynthesis of polyketides, a therapeutically and structurally diverse class of natural products, where we employed both synthetic chemistry and biochemical techniques to validate complex metabolic processes. One such example pertained to the uncertainty surrounding the regiochemistry of dehydration and …
