Defining Benthic Organism Exposure: Bioavailability And Effects Of Non-Polar Organics, Marc Samuel Greenberg

Browse all Theses and Dissertations

Laboratory and field tests were conducted to evaluate the hypothesis that factors such as the total organic carbon (TOC) contents and groundwater-surface water interactions (GSI) in the sediments can affect chemical desorption, bioavailability and benthic organism exposure. Laboratory studies were conducted with the polycyclic aromatic hydrocarbon fluoranthene (FLU) and the herbicide trifluralin (TF). Toxicokinetic parameters were determined for Lumbriculus variegatus and Hyalella azteca in water-only exposures to 0, 5, 20 and 50 µg/L of the compounds and bioaccumulation was measured during exposures to 0, 100 and 200 mg/kg of FLU and TF spiked onto sediments from Lakes Erie and Huron. …

The Synthesis Of Bromoethoxy And Vinylbenzyloxy Substituted Nlo Chromophores, Michael Joseph Matuszewski

Browse all Theses and Dissertations

Multiphoton-absorption processes have recently attracted growing interest because of the potential impact on a wide spectrum of applications, ranging from data storage to photodynamic therapy. From the materials standpoint, particular interest is centered in designing chromophores that exhibit a large two-photon cross-section. The current research is focused on establishing synthetic routes that lead to the formation of derivatives of N,N-diphenyl-(7-benzothiazol-2-yl)-9,9-diethyl-9H-fluoren-2-ylamine which contain meta functionalization. A bromoethoxy functionalized chromophore, N-phenyl-N-(3-(2-bromoethoxy)phenyl)-7-(benzothiazol-2-yl)-9,9-diethyl-9H-fluoren- 2-ylamine , was synthesized and used as a polymer pendent while a vinylbenzyloxy chromophore, N-phenyl-N-(3-(4-vinylbenzyloxy)phenyl)-7- (benzothiazol-2-yl)-9,9-diethyl-9H-fluoren-2-ylamine, was synthesized as a hydrosilation substrate. A compound containing three chromophores, 1,3,5-tris(3-(N-phenyl- 4-(7-(benzothiazol-2-yl)-9,9-diethyl-9H-fluoren-2- ylanilino)phenoxymethyl)benzene, has …

United States National Aeronautics and Space Administration: Publications

With the launch of NASA’s Terra satellite and the MODerate Resolution Imaging Spectroradiometer (MODIS), operational Bidirectional Reflectance Distribution Function (BRDF) and albedo products are now being made available to the scientific community. The MODIS BRDF/Albedo algorithm makes use of a semiempirical kernel-driven bidirectional reflectance model and multidate, multispectral data to provide global 1-km gridded and tiled products of the land surface every 16 days. These products include directional hemispherical albedo (black-sky albedo), bihemispherical albedo (white-sky albedo), Nadir BRDF-Adjusted surface Reflectances (NBAR), model parameters describing the BRDF, and extensive quality assurance information. The algorithm has been consistently producing albedo and NBAR …

Entropy Splitting For High-Order Numerical Simulation Of Compressible Turbulence, N. D. Sandham, Q. Li, Helen C. Yee

United States National Aeronautics and Space Administration: Publications

A stable high-order numerical scheme for direct numerical simulation (DNS) of shock-free compressible turbulence is presented. The method is applicable to general geometries. It contains no upwinding, artificial dissipation, or filtering. Instead the method relies on the stabilizing mechanisms of an appropriate conditioning of the governing equations and the use of compatible spatial difference operators for the interior points (interior scheme) as well as the boundary points (boundary scheme). An entropy-splitting approach splits the inviscid flux derivatives into conservative and nonconservative portions. The spatial difference operators satisfy a summationby- parts condition, leading to a stable scheme (combined interior and boundary …

Organizational Climate And Commitment: A Case Study Of An Urban Nonprofit Organization, William Sawyer Grant

Theses and Dissertations in Urban Services - Urban Management

This qualitative study investigates the relationship between the two constructs: Organizational Climate and Organizational Commitment.

Litwin and Stringer (1968) suggested that a molar model is needed to explain employee behavior and motivation. Climate was proposed as this molar construct. Research concerning Organizational Climate resulted in multiple definitions and little consensus concerning the number and use of multiple dimensions of this construct. The almost exclusive use of survey methods coupled with methodological confusion with Organizational Culture created difficulty with the use of this important construct.

Organizational Commitment research resulted in a number of competing definitions. Research by Meyer and Allen (1997) …

Using Commercial Finite Element Code Called Abaqus In Modeling Hybrid Constrained Layers Damping Beam Structure And Quantitative Determination Of The Stability Of Implant-Bone Interface Using Resonance Frequency Analysis, Daniel Delgado Jr.

Theses and Dissertations - UTB/UTPA

In Chapter 1, it has been demonstrated that the damping treatments for beam and plate structures are effective, and the vibrational behaviors of the systems considered are influenced by many geometrical and material parameters. This has led to an interest in developing advanced “intelligent” structures. In the past, passive and active damping mechanisms have been used to reduce vibration. The uses of passive constrained layers are limited, but it has dissipative qualities for all the modes of the structure; and the uses of active constrained layers are limited to a single mode control. Recent published papers, many have suggested that …

A New Optimal Nonlinear Control Method And Its Application To Missile Guidance Law Design, Ming Xin, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In this paper, a new nonlinear control synthesis technique (q-D approximation) is discussed. By adding perturbations to the cost function this approach achieves a suboptimal solution to the Hamilton-Jacobi- Bellman (HJB) equation. By manipulating the perturbation terms both asymptotic stability and optimality properties are obtained. An application to the design of missile guidance law is presented and is compared with a similar technique (State Dependent Riccati Equation technique) used in problems of this class. © 2002 by the author(s).

State Dependent Riccati Equation Based Spacecraft Attitude Control, Ming Xin, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

We present a new optimal control approach to the robust spacecraft attitude control in the framework of State Dependent Riccati Equation (SDRE) technique. To treat this highly nonlinear control system, we formulate it as a nonlinear optimal regulator problem. SDRE technique was well applied to this class of attitude control problem. We also synthesize a neural network based extra controller to achieve the robustness in the presence of the parameter uncertainties. A general spacecraft attitude regulation problem was studied to show the effectiveness of SDRE approach and robust extra control design. © 2002. Published by the American Institute of Aeronautics …

A Functional Basis For Engineering Design: Reconciling And Evolving Previous Efforts, Julie Hirtz, Robert B. Stone, Daniel A. Mcadams, Simon Szykman, Kristin L. Wood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In engineering design, all products and artifacts have some intended reason behind their existence: the product or artifact function. Functional modeling provides an abstract, yet direct, method for understanding and representing an overall product or artifact function. Functional modeling also strategically guides design activities such as problem decomposition, physical modeling, product architecting, concept generation, and team organization. A formal function representation is needed to support functional modeling, and a standardized set of function-related terminology leads to repeatable and meaningful results from such a representation. We refer to this representation as a functional basis; in this paper, we seek to reconcile …

Supersonic Combustion And Mixing Characteristics Of Hydrocarbon Fuels In Screamjet Engines, Ahmed A. Taha

The Development And Validity Testing Of The Risk Communicator Style Scale And The Risk Knowledge Index., Jason Steven Wrench

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined the current lack of quantitative research in the area of risk communication. This study set out to develop and then validate two different scales that could be used for future research in the area of risk communication. The first scale created in this study is the Risk Communicator Style Scale. The scale is based on the technical and democratic models of risk communication described by Fiorino (1989). This study found a conceptual problem with Fiorino's original conceptualization of technical risk communication. Fiorino's original conceptualization of technical communication tried to equate the use of scientific and statistical information …

Understanding Retroviral Replication: Roles Of Nucleocapsid And Rnase H During Reverse Transcription In Vivo., Wen-Hui Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Retroviruses exhibit high genetic variability, which is generated by mutations and recombination during viral replication. This can lead to rapid emergence of viral variants resistant to antiretroviral drugs. A better understanding of retroviral replication may lead to the development of improved antiviral drug therapy and effective vaccines to retrovirus-related diseases. The fact that retroviral nucleocapsid protein (NC) is multifunctional and plays crucial roles in viral replication makes it a good target for antiviral drug development. By studying how NC affects reverse transcriptase (RT) template switching, the in vivo role of NC during reverse transcription can be explored. Using a sensitive …

Why National Missile Defense: A Test Of Three Competing Models., Christopher Lee Campbell

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation seeks to answer the question of why the United States is pursuing the deployment of a national missile defense (NMD) system at the present time. The explanation most often given by national security policy makers is that it is being constructed in response to the weapons programs of “rogue states.” States such as North Korea, Iran, and Iraq are seen as actively developing weapons of mass destruction (WMD) and the capability to deliver these weapons to the U.S. mainland. However, the proposal of this system poses problems. First, it has made many U.S. allies fear that its foreign …

A Tabu Search Approach For The Dynamic Space Allocation Problem., Juan R. Jaramillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

The dynamic space allocation problem (DSAP) is the assigning of activities to workspaces and idle resources to storage spaces while minimizing the total distance traveled by the resources during project duration. The inputs of the DSAP are: the schedule of project activities and the resources required to perform the activities, the layout of the floor plan, the capacity of the storage spaces, and the distances between locations. The output is a sequence of layouts containing the assignments of the activities and their resources to workspaces, as well as the idle resources to storage spaces. The DSAP is related to some …

Organic Beef A Production Guide, Steven Mccoy

Bulletins 4000 -

Premium markets are expanding worldwide for certified organic and biodynamic beef products – those grown in accordance with recognised organic production and processing standards.

Many agricultural areas in Australia have the potential to produce organic beef, and several Western Australian and Eastern States organic producers are already exporting to Japan. Supermarkets such as Coles and Woolworths have started to build the Australian domestic market.

Converting to an organic system can be easier - requiring fewer changes - in ‘low input’ rangeland cattle production than in more intensive pasture-based or feedlot production. But regardless of the type of enterprise, managing organic …

Symmetrically Coated Pellicle Beam Splitters For Dual Quarter-Wave Retardation In Reflection And Transmission, Rasheed M.A. Azzam, Fadi A. Mahmoud

Electrical Engineering Faculty Publications

A trilayer pellicle that consists of a high-index center layer that is symmetrically coated on both sides by a low-index film can be designed to produce differential reflection and transmission phase shifts of ∓90° at oblique incidence and equal throughput for the p and the s polarizations. Such a device splits a beam of incident linearly polarized light into two orthogonal circularly polarized components that travel in well-separated angular directions. Examples of infrared dual quarter-wave retarders that use a symmetrically coated Ge pellicle at 77° angle of incidence are presented. A 50–50% splitter requires a symmetric pellicle with at least …
