Pairing Educational Robotics With Geospatial Technologies In Informal Learning Environments, Bradley Barker, Neal Grandgenett, Gwen Nugent, Viacheslav Adamchuk Aug 2010

Pairing Educational Robotics With Geospatial Technologies In Informal Learning Environments, Bradley Barker, Neal Grandgenett, Gwen Nugent, Viacheslav Adamchuk

Journal of Youth Development

Educational robotics, when paired with geospatial technologies and taught in an informal educational environment, can be an innovative strategy to teach youth about science, technology, engineering, and mathematic (STEM) concepts. However, little is known about the true effects on conceptual knowledge and associated attitudes. Therefore, this study was conducted to examine the short- term effects of a series of five-day summer robotics/geospatial camps held in Nebraska. The study was conducted at six diverse locations and consisted of a five-day 4-H camp experience. The study examined the experiences of 147 youth between the ages of 10 and 15. A pretest- posttest …

Introducing Writing Across The Curriculum Into China: Feasability And Adaptation, Dan Wu Aug 2010

Introducing Writing Across The Curriculum Into China: Feasability And Adaptation, Dan Wu

All Dissertations

Writing Across the Curriculum (WAC) is a successful educational movement initiated in the US in the 1970s to promote better teaching and learning. It has developed to incorporate writing, speaking, digital educational technologies, and other communication modalities in the past several decades. WAC initiatives have now been successfully transplanted outside of the U.S. in nations and areas such as Australia, Sweden, Germany, and Hong Kong, yet one country that has not endorsed a WAC approach is China. Given the current tension between access and quality for Chinese higher education after an unprecedented enrollment expansion, incorporating WAC approaches is currently a …

Numerical Modeling Of Contaminant Transport In Fractured Porous Media Using Mixed Finite Element And Finite Volume Methods, Chen Dong Aug 2010

Numerical Modeling Of Contaminant Transport In Fractured Porous Media Using Mixed Finite Element And Finite Volume Methods, Chen Dong

All Theses

A mathematical model for contaminant species passing through fractured porous media is presented. In the numerical model, we combine two locally conservative methods, i.e. mixed finite element (MFE) and the finite volume methods. Adaptive triangle mesh is used for effective treatment of the fractures. A hybrid MFE method is employed to provide an accurate approximation of velocities field for both the fractures and matrix which are crucial to the convection part of the transport equation. The finite volume method and the standard MFE method are used to approximate the convection and dispersion terms respectively. Numerical examples in different fractured media …

'Shored Against The Ruins': Edifying Romantic And Modernist Thought, Leslie Haines Aug 2010

'Shored Against The Ruins': Edifying Romantic And Modernist Thought, Leslie Haines

All Theses

This thesis explores the continuing aesthetic, philosophical, and social influences of Romantic and Modernist poetics. I trace the influence of Romanticism and Modernism as one that allows for a medium of expression that more clearly interprets both the act of reading and writing. These artistic periods and styles mutually serve to establish and validate enlightened ways of thinking that are currently lacking in the present day. I look to the poetry, philosophy, and prophecy of artists from both eras as they fuse and diffuse demonstrating the unique points of connection and disconnection for each of the poets whose texts are …

State Estimation For Diffusion Systems Using A Karhunen-Loeve-Galerkin Reduced-Order Model, Justin Mattimore Aug 2010

State Estimation For Diffusion Systems Using A Karhunen-Loeve-Galerkin Reduced-Order Model, Justin Mattimore

All Theses

This thesis focuses on generating a continuous estimate of state using a small number of sensors for a process modeled by the diffusion partial differential equation(PDE). In biological systems the diffusion of oxygen in tissue is well described by the diffusion equation, also known by biologists as Fick's first law. Mass transport of many other materials in biological systems are modeled by the diffusion PDE such as CO2, cell signaling factors, glucose and other biomolecules.
Estimating the state of a PDE is more formidable than that of a system described by ordinary differential equations (ODEs). While the state variables of …

Metalloporphyrin-Catalyzed Reduction Reactions Of Hexavalent Chromium, Rong Zhang Aug 2010

Metalloporphyrin-Catalyzed Reduction Reactions Of Hexavalent Chromium, Rong Zhang

All Theses

Previous studies have demonstrated that the reduction of oxidized organic and inorganic contaminants could be catalyzed by electron shuttle systems, which generally were biological organic macrocycle complexes with transition metals. Metalloporphyrins (MPs) and their derivatives are well known electron shuttles for many biogeochemical systems. The objective of this research was to study the catalytic capabilities of selected MPs for the reduction of hexavalent chromium (Cr(VI)) in the presence of reducing agents. Zero valent iron (ZVI) was chosen as the primary electron donor in the experimental systems. Protoporphyrin IX (Proto) and Uroporphyrin I (Uro) are naturally occurring porphyrins produced during heme …

Institutionalization, Technology, And Power: The Ideological Context Of Style Organizations, Dustin Wilson Aug 2010

Institutionalization, Technology, And Power: The Ideological Context Of Style Organizations, Dustin Wilson

All Theses

Organizations have the power to establish the norms of discourse within various fields through organizational style guides. These style guides determine the conventions of discourse that professionals use every day. In this thesis, I explore and articulate the ideological context of some style guides in prominent professions. The institutionalization of discourse is seen through the history of style manuals and is particularly noted within the discourse of contemporary organizations that create style guides. Through an application of the theories of Foucault and Habermas, I discuss how these organizations institutionalize discourse and perpetuate a system of purposive-rational action. In this thesis, …

Factors Influencing The Adsorption Of Synthetic Organic Compounds By Carbon Nanotubes In Aquatic Environments, Ting Shao Aug 2010

Factors Influencing The Adsorption Of Synthetic Organic Compounds By Carbon Nanotubes In Aquatic Environments, Ting Shao

All Theses

Carbon nanotubes (CNTs) are allotropes of carbon consisting of sheets of carbon atoms covalently bonded in hexagonal arrays that are seamlessly rolled into a hollow, cy-lindrical shape with both ends rounded by fullerene-like caps. As large amounts of CNTs have been manufactured and significant growth is expected in commercial CNT produc-tion, there is a major concern over their health and environmental risks once they enter into the environment. In aquatic systems, CNTs are likely to adsorb organic chemicals and aggregate as bundles due to their extremely hydrophobic surfaces. The aggregation state of CNTs plays a significant role in their fate …

Effect Of Abiotic Factors On Lead Corrosion In Drinking Water Systems, Bin Yang Aug 2010

Effect Of Abiotic Factors On Lead Corrosion In Drinking Water Systems, Bin Yang

All Theses

A major shift in water disinfection has been happening over the past few years from chlorination to chloramination. Chloramination is considered advantageous to chlorination due to the decreased formation of hazardous disinfection byproducts (DBPs) that are regulated by the Environmental Protection Agency (EPA) under the Disinfectants/Disinfection By-Products Rule. Despite the advantage of chloramination in generating less DBPs, unexpected increases in lead concentrations have recently been uncovered and receiving intensive attention. Because lead is neurologically toxic, research is needed to investigate the mechanisms involved in lead corrosion in such systems and to develop counteractive approaches. Currently, there is a very poor …

Fantasy Football: Analyzing Fantasy Themes In America's Rhetorical Pastime, Frankie Christ Aug 2010

Fantasy Football: Analyzing Fantasy Themes In America's Rhetorical Pastime, Frankie Christ

All Theses

Fantasy football has emerged as a male-bonding experience of our online age. In understanding the formation of a rich rhetorical community, a close examination of how these fantasy football communities represent the larger culture is required. This thesis uses Ernest Bormann's theoretical framework of fantasy theme analysis to examine how the sharing of group fantasies creates a symbolic convergence. Once symbolic convergence has occurred, group members are then able to share rhetorical visions that shape their world's view. In the case of this thesis, Bormann's methods have been modified to better understand the small group dynamics of fantasy football participants. …

Anaerobic Bio-Oxidation Of Vinyl Chloride And Ethene, Anthony Reid Aug 2010

Anaerobic Bio-Oxidation Of Vinyl Chloride And Ethene, Anthony Reid

All Theses

Tetrachloroethene and trichloroethene are among the most prevalent groundwater contaminants found at hazardous waste sites throughout the United States. Since implementing some of the common treatment methods to remediate these hazardous waste sites would exceed hundreds of billions of dollars, there is considerable interest in reducing costs while achieving remediation regulations. Under anaerobic conditions, these compounds can undergo reduction reactions known as reductive dechlorination. This occurs when an electron donor provides the reducing equivalents needed to replace the chlorine atoms with hydrogen atoms. The daughter products from higher chlorinated ethenes are ethene and ethane which can be used to document …

The Effects Of Physical Factors On The Adsorption Of Synthetic Organic Compounds By Activated Carbons And Activated Carbon Fibers, Hatice Kose Aug 2010

The Effects Of Physical Factors On The Adsorption Of Synthetic Organic Compounds By Activated Carbons And Activated Carbon Fibers, Hatice Kose

All Theses

Activated carbons (ACs) and activated carbon fibers (ACFs) have been extensively used for the removal of synthetic organic compounds (SOCs) that have been found to be toxic, carcinogenic, mutagenic or teratogenic. Adsorption of these compounds on ACs and ACFs are controlled by both physical factors and chemical interactions, which depend on the characteristics of the adsorbent (surface area, pore size distribution (PSD), and surface chemistry), the nature of the adsorbate (molecular weight and size, functional groups, polarity, solubility), and the condition of the background solution (pH, temperature, presence of competitive solutes, ionic strength). Since there are several mechanisms that can …

Hydromechanical Interference Slug Tests In A Fractured Biotite Gneiss, Trever Slack Aug 2010

Hydromechanical Interference Slug Tests In A Fractured Biotite Gneiss, Trever Slack

All Theses

Fractures are ubiquitous in the shallow crust and they commonly control the flow and storage of fluids in rock. Estimating transmission and storage properties resulting from fractures is commonly accomplished by interpreting the pressure signals caused by stressing an aquifer during a pumping or slug test. Fractures deform in response to pressure changes during well tests, and measuring and interpreting the deformation along with the pressure change is a way to potentially increase the information about storage and transmission properties. Tests where the pressure and deformation are coupled are called hydromechanical well tests. Previous investigations have focused on the effects …

Behavioral Animation For Maya Particles Using Steering Forces, Edgar Rodriguez Aug 2010

Behavioral Animation For Maya Particles Using Steering Forces, Edgar Rodriguez

All Theses

Maya has various built-in solutions for modeling effects. Maya does not, however, offer a built-in solution for modeling so called 'steering behaviors.' While users may rely on particle expressions or scene rigs, these solutions are generally time consuming and ultimately limiting in their cross application. Accordingly, Maya's particle system was extended, by implementing a new force, which can be used to model a set of steering behaviors. The new force was coded in Python and was implemented using Maya's Python Application Programming Interface ('API'). The new force can be used in conjunction with the particle system's existing forces and Maya's …

Fosinopril, A Potential Substrate For Mrp2, Competes With Several High Use Pharmaceuticals For Elimination, Benjamin Green Aug 2010

Fosinopril, A Potential Substrate For Mrp2, Competes With Several High Use Pharmaceuticals For Elimination, Benjamin Green

All Theses

The multidrug-resistance associated protein 2 (MRP2) is a membrane-bound transporter responsible for the efflux of a variety of drugs and endogenous compounds. MDCK cells transfected with the human MRP2 gene were used to assess whether several highly used pharmaceuticals were potential substrates by examining their differential toxicity, accumulation, and efflux. Fosinopril, an ACE inhibitor, was 2.4-fold less toxic to the MRP2 transfected cells compared to mock transfected cells, suggesting that fosinopril is a potential MRP2 substrate. In addition, fosinopril was effluxed more rapidly, as the MRP2 cells only retained 13 % of the dosed fosinopril after 20 minutes compared with …
