Isotopic Tracers As Evidence Of Denitrification In The Karlsruhe Aquifer, Eben J. Spencer

Theses and Dissertations

The Karlsruhe Aquifer of north-central North Dakota has experienced considerable nitrate contamination sparking an investigation by the North Dakota State Water Commission. Certain portions of the aquifer have experienced nitrate-N concentrations of up to seven times the drinking water standard. Although contamination is evident it is possible the NO₃¯ is naturally being eliminated by denitrification, whereby bacteria reduce NO₃¯ to nitrogen gas. Evidence of denitrification may be illustrated by accelerated reduction of NO₃¯ relative to the conservative tracer Cl¯ coupled with an increase in the heavy isotopes of 15N and 18O within the NO₃¯ ion. Such an increase is not …

A Template Functional-Gage Design Using Parameter-File Table In Autodesk Inventor, Cheng Lin, Moustafa Moustafa

Engineering Technology Faculty Publications

A systematic approach using Autodesk Inventor to design the functional gages of Geometric Dimensioning & Tolerancing (GD&T) is presented. The gages can be used to check straightness, angularity, perpendicularity, parallelism, and position tolerances of a part when geometric tolerances are specified with Maximum Material Condition (MMC). Four steps are proposed to accomplish the task: (1) creation of two-dimensional (2-D) initial template files, (2) generation of hierarchical folders for the template files, (3) creation a 3-D gage model from a specific template file, and (4) dimensioning and generation of the gage drawing. Results show that, by following this approach, students can …

Deep Drains To Manage Groundwater, Neil Cox, Sylvia Tetlow, Neil Coles

Bulletins 4000 -

A channel that is 1.0 m to 3.0 m in depth is considered to be a deep drain. The drain is excavated to a depth that is sufficient to intercept the watertable in order to capture and convey that groundwater from flat, poorly drained land.

The drain can either be ‘open’ to allow the inflow of surface water or ‘leeved’ to exclude surface water. An open deep drain has its spoil banks placed on one side or on alternate sides of the channel (Figure 1) while a leveed deep drain has continuous spoil banks placed on both sides of the …

Beyond The Roof, Faye. Pelosi

Electronic Theses and Dissertations 2000 - 2009

Ultimately, these verses are reflections of paintings (not necessarily paintings made with brush and oil, but paintings created by Nature, memory, and so forth). Each poem is also a painting and each painting is also a poem in the sense that the poetry should work the way a painting does by presenting a vivid image and idea. In every case, one has stemmed from the other. I want to translate the visual arts into writing, which includes the visual art of imagination because images are my natural language. These verses are an attempt at intermixing the categories (language and image), …

Valuing Diversity As An Imperative For Fulfilling The Mission Of The Church, Walter B. T. Douglas

Faculty Publications

Demographic shifts, cultural and ethnic diversity, globalization, and the rapid expansion of the church in the southern hemisphere strongly suggest that the future growth of Adventism may emerge in the developing nations. This article is an attempt to engage in conversation on the changing face of Adventism and the challenge this new Adventism presents across cultural, ethnic, and racially diverse communities. This article provides the church with a window of opportunity to view diversity not as an event but as a process to maximize and explore the richness of its diversity and to see it not as a problem to …

Nature/Culture Clash: The Transnational Trade In Gmos, Dayna Scott

All Papers

This paper aims to offer a fresh perspective into what is at stake in the cross-cultural trade dispute over genetically-modified organisms (GMOs) by subjecting a particular discursive sample, the parties’ submissions to the WTO panel, to critical scrutiny. The first step involves a survey of the rhetorical strategies deployed by the parties’ in the presentation of their arguments to the Panel. Next, I embark on the task of ‘disassembling the double helix’. My use of the term ‘double helix’ in this analysis refers to the close coupling of scientific and legal discourses in the trade regime: science and law are …

Blurring The Boundaries Between Immigration And Crime Control After Sept. 11th, Teresa A. Miller

Journal Articles

Although the escalating criminalization of immigration law has been examined at length, the social control dimension of this phenomenon has gone relatively understudied. This Article attempts to remedy this deficiency by tracing the relationship between criminal punishment and immigration law, demonstrating that the War on Terror has further blurred these distinctions and exposing the social control function that pervades immigration law enforcement after September 11th prioritized counterterrorism. In doing so, the author draws upon the work of Daniel Kanstroom, Michael Welch, Jonathan Simon and Malcolm Feeley.

The Pedagogical Significance Of The Bush Stem Cell Policy: A Window Into Bioethical Regulation In The United States (President George W. Bush, Fifth Anniversary Essay Collection), O. Carter Snead

Journal Articles

The enormous significance of the Bush stem cell funding policy has been evident since its inception. The announcement of the policy on August 9, 2001 marked the first time a U.S. president had ever taken up a matter of bioethical import as the sole subject of a major national policy address. Indeed, the August 9th speech was the President's first nationally televised policy address of any kind. Since then, the policy has been a constant focus of attention and discussion by political commentators, the print and broadcast media, advocacy organizations, scientists, elected officials, and candidates for all levels of office …

Some Varieties And Vicissitudes Of Lochnerism, Barry Cushman

Journal Articles

This article is a contribution to the Lochner Centennial Symposium at Boston University School of Law. Until recently, a consensus appeared to be emerging among constitutional historians concerning how best to interpret Lochner-era decisions involving Fifth and Fourteenth Amendment challenges to state and federal economic regulation. After decades during which the Court's jurisprudence had been characterized as the product of a reactionary judiciary's commitments to Social Darwinism and laissez-faire economics, more recent scholars had come to see the Court's police powers decisions as animated by what Professor Howard Gillman has called the principle of neutrality. On this view, the Court's …

Optimal Control Parameters For A Upfc In A Multimachine Using Pso, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

The crucial factor affecting the modern power systems today is load flow control. The unified power flow controller (UPFC) is an effective means for controlling the power flow and can provide damping capability during transient conditions. The UPFC is controlled conventionally using PI controllers. The optimal design of the PI controllers for a UPFC is a challenging task and time consuming using the conventional techniques. This paper presents an approach using particle swarm optimization (PSO) for the design of optimal conventional controllers for a UPFC in a multimachine power system. Simulation results are presented to show the effectiveness of the …

Trehalose Loading Through The Mitochondrial Permeability Transition Pore Enhances Desiccation Tolerance In Rat Liver Mitochondria., Xiang-Hong Liu, Alptekin Aksan, Michael Menze, Steven Hand, Mehmet Toner

Faculty and Staff Scholarship

Trehalose has extensively been used to improve the desiccation tolerance of mammalian cells. To test whether trehalose improves desiccation tolerance of mammalian mitochondria, we introduced trehalose into the matrix of isolated rat liver mitochondria by reversibly permeabilizing the inner membrane using the mitochondrial permeability transition pore (MPTP). Measurement of the trehalose concentration inside mitochondria using high perfOrmance liquid chromatography showed that the sugar permeated rapidly into the matrix upon opening the MPTP. The concentration of intra matrix trehalose reached 0.29 mmoVmg protein (-190 mM) in 5 min. Mitochondria, with and without trehalose loaded into the matrix, were desiccated in a …

Cryopreservation Of Human Hematopoietic Stem And Progenitor Cells Loaded With Trehalose : Transient Permeabilization Via The Adenosine Triphosphate-Dependent P2z Receptor Channel., Sandhya S. Buchanan, Michael A. Menze, Steven C. Hand, David W. Pyatt, John F. Carpenter

Faculty and Staff Scholarship

Hematopoietic stem and progenitor cells (HPCs) are a heterogenic population of cells used to treat a number of human diseases. Multilineage differentiation is a required function in successful hematopoietic reconstitution after transplantation of cryopreserved grafts. Conventional use of the cryoprotectant dimethyl sulfoxide (DMSO) has resulted in some reports of infusion related toxicity attributed to DMSO and/or damage to cells during freezethawing procedures. The purpose of this study was to explore the use of trehalose, a nontoxic disaccharide of glucose, as an alternative cryoprotectant. Trehalose was introduced into HPCs using the P2Z receptor, known to form nonselective pores in the presence …

Iterative Equalization Using Improved Block Dfe For Synchronous Cdma Systems, Sang-Yick Leong, Kah-Ping Lee, Y. Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

Iterative equalization using optimal multiuser detector and trellis-based channel decoder in coded CDMA systems improves the bit error rate (BER) performance dramatically. However, given large number of users employed in the system over multipath channels causing significant multiple-access interference (MAI) and intersymbol interference (ISI), the optimal multiuser detector is thus prohibitively complex. Therefore, the sub-optimal detectors such as low-complexity linear and non-linear equalizers have to be considered. In this paper, a novel low-complexity block decision feedback equalizer (DFE) is proposed for the synchronous CDMA system. Based on the conventional block DFE, the new method is developed by computing the reliable …

Making The Graduate-Industry Connection, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

Many utilities are beginning to ramp up their recruiting and hiring efforts to attract bright young engineering graduates into the industry to replace the large numbers of engineers that have recently retired or will retire in the next few years. Unfortunately, the long drought in hiring brought on by the uncertainty of deregulation and the perspective that the industry is "old and conservative" has caused a mismatch in the interests of young engineers and the companies that want to hire them. in addition, the number of young people pursuing engineering degrees is decreasing as they become attracted to other lucrative …

Mlp/Rbf Neural-Networks-Based Online Global Model Identification Of Synchronous Generator, Jung-Wook Park, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

This paper compares the performances of a multilayer perceptron neural network (MLPN) and a radial basis function neural network (RBFN) for online identification of the nonlinear dynamics of a synchronous generator in a power system. The computational requirement to process the data during the online training, local convergence, and online global convergence properties are investigated by time-domain simulations. The performances of the identifiers as a global model, which are trained at different stable operating conditions, are compared using the actual signals as well as the deviation signals for the inputs of the identifiers. Such an online-trained identifier with fixed optimal …

Fly Ash As A Soil Amendment In The Northern Red River Valley, Amy Decker

Undergraduate Theses and Senior Projects

Combustion of coal occurs worldwide to produce energy for numerous residential and industrial processes. During coal combustion, byproducts including fly ash, bottom ash and slag are formed (Lafarge, 2004). By standard regulations, power plants in the United States and many other countries must effectively capture and dispose of these byproducts. Over 118 million tons of combustion byproducts are produced and captured each year in the United States alone. Disposal of this extraordinary amount of waste is difficult and costly. Finding ways to turn this waste into a resource has been necessary, and at times, profitable.

The past fifty years has …

International Freight Transport Multimodal Development In Developing Countries: The Case Of Bangladesh, Dewan Mohammad Zahurul Islam

Plymouth Business School Theses

An efficient transport system is essential for an efficient supply chain to facilitate international trade. To utilise all cheaper resources, such as labour in Bangladesh, companies receive supplies from one coxintry (e.g. in Hong Kong), produce the products in another country, and sell them in other countries (e.g. European countries). Thus the production and consumption has turned into a global activity with transport filling the gaps among them. To perform the transport function a carrier may require the use of more than one mode, the so-called multimodal transport. Multimodal transport, an integrated systems approach, can be defined as the most …
