A “Sprinkler” Vegetative Treatment System, Jason Gross, Chris G. Henry Jan 2007

A “Sprinkler” Vegetative Treatment System, Jason Gross, Chris G. Henry

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Vegetative Treatment Systems have historically been a practice for the treatment and utilization of open lot livestock wastes. Use of these systems has been rejuvenated in recent years. A “sprinkler” vegetative treatment area (VTA) has been designed and developed as a proof of concept for addressing challenges experienced with small and medium Animal Feeding Operations. The focus of this paper is to report on the design, economics, challenges and the lessons learned on the development of this system. Cost data shows the cost of a “sprinkler” VTS to range between $31 to $63/head, compared to $51 to $170/head for a …

Discrimination Of Bacteria And Bacteriophages By Raman Spectroscopy And Surface-Enhanced Raman Spectroscopy, Lindsay J. Goeller, Mark R. Riley Jan 2007

Discrimination Of Bacteria And Bacteriophages By Raman Spectroscopy And Surface-Enhanced Raman Spectroscopy, Lindsay J. Goeller, Mark R. Riley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Detection of pathogenic organisms in the environment presents several challenges due to the high cost and long times typically required for identification and quantification. Polymerase chain reaction (PCR) based methods are often hindered by the presence of polymerase inhibiting compounds and so direct methods of quantification that do not require enrichment or amplification are being sought. This work presents an analysis of pathogen detection using Raman spectroscopy to identify and quantify microorganisms without drying. Confocal Raman measurements of the bacterium Escherichia coli and of two bacteriophages, MS2 and PRD1, were analyzed for characteristic peaks and to estimate detection limits using …

Biological Engineering is a new and unique discipline that encompasses a wide range of engineering theory and practice connected to and derived from biology. This emerging science-based engineering discipline and related applications are experiencing rapid growth. Prior to publication of JBE there is no refereed publication that encompasses the breadth and depth of biological engineering as a science- based discipline, rather than a collection of applications. Our goal in publishing JBE is to provide a forum for topics that address the foundational …


Biocompatibility Of Te–As–Se Glass Fibers For Cell-Based Bio-Optic Infrared Sensors, Allison A. Wilhelm, Pierre Lucas, Diana L. Derosa, Mark R. Riley Jan 2007

Biocompatibility Of Te–As–Se Glass Fibers For Cell-Based Bio-Optic Infrared Sensors, Allison A. Wilhelm, Pierre Lucas, Diana L. Derosa, Mark R. Riley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The chemical stability and toxicity of Te–As–Se (TAS) infrared fibers are investigated. These fibers are used for biosensing applications that involve direct contact with live cultivated human cells. It is shown that TAS fibers exhibit a small oxidation layer after extended exposure to air. This layer is highly soluble in water and easily removed. However, the TAS glass itself is stable in water over several days. While oxidized fibers release arsenate ions, which result in toxic effects to the cells, fresh or washed fibers show no toxic effects. A good correlation is shown between surface etching and the disappearance of …


Subsurface Characterization Using Textural Features Extracted From Gpr Data, R. S. Freeland, Lameck O. Odhiambo Jan 2007

Subsurface Characterization Using Textural Features Extracted From Gpr Data, R. S. Freeland, Lameck O. Odhiambo

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Subsurface conditions can be non-intrusively mapped by observing and grouping patterns of similarity within ground-penetrating radar (GPR) profiles. We have observed that the intricate and often visually indiscernible textural variability found within a complex GPR image possesses important parameters that help delineate regions of similar subsurface characteristics. In this study, we therefore examined the feasibility of using textural features extracted from GPR data to automate subsurface characterization. The textural features were matched to a “fingerprint” database of previous subsurface classifications of GPR textural features and the corresponding physical probings of subsurface conditions. Four textural features (energy, contrast, entropy, and homogeneity) …


Analysis Of An Ion‐Selective Electrode Based Methodology For Integrated On‐The‐Go Mapping Of Soil Ph, Potassium, And Nitrate Contents, B. Sethuramasamyraja, V. I. Adamchuk, D. B. Marx, A. Dobermann, G. E. Meyer, D. D. Jones Jan 2007

Analysis Of An Ion‐Selective Electrode Based Methodology For Integrated On‐The‐Go Mapping Of Soil Ph, Potassium, And Nitrate Contents, B. Sethuramasamyraja, V. I. Adamchuk, D. B. Marx, A. Dobermann, G. E. Meyer, D. D. Jones

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Knowledge of the spatial variation of soil attributes is critical for precision agriculture. On‐the‐go soil sensors have been able to provide relatively high mapping density while assessing this variation. A new ion‐selective electrode (ISE) based approach was developed and tested for simultaneous mapping of soil pH, residual nitrate (NO3 -), and soluble potassium (K+) contents. In this article, results of laboratory experiments investigating the effects of key measurement factors on ISE performance are presented. In addition to four different soils, these factors included: soil/water ratio (SWR), quality of water used for electrode rinsing (QWR) and for …

Protection With Recombinant Clostridium Botulinum C1 And D Binding Domain Subunit (Hc) Vaccines Against C And D Neurotoxins, Robert P. Webb, Theresa J. Smith, Patrick M. Wright, Vicki A. Montgomery, Michael M. Meagher, Leonard A. Smith

Michael Meagher Publications

Recombinant botulinum Hc (rBoNT Hc) vaccines for serotypes C1 and D were produced in the yeast Pichia pastoris and used to determine protection against four distinct BoNT C and D toxin subtypes. Mice were vaccinated with rBoNT/C1 Hc, rBoNT/D Hc, or with a combination of both vaccines and challenged with BoNT C1, D, C/D, or D/C toxin. Mice receiving monovalent vaccinations were partially or completely protected against homologous toxin and not protected against heterologous toxin. Bivalent vaccine candidates completely survived challenges from all toxins except D/C toxin. These results indicate the recombinant C1 and D Hc vaccines are not only …

Spatiotemporal Variations In Growing Season Exchanges Of Co2, H2o, And Sensible Heat In Agricultural Fields Of The Southern Great Plains, Marc L. Fischer, Dave P. Billesbach, Joseph A. Berry, William J. Riley, Margaret S. Torn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Climate, vegetation cover, and management create finescale heterogeneity in unirrigated agricultural regions, with important but not well quantified consequences for spatial and temporal variations in surface CO2, water, and heat fluxes. Eddy covariance fluxes were measured in seven agricultural fields—comprising winter wheat, pasture, and sorghum—in the U.S. Southern Great Plains (SGP) during the 2001–03 growing seasons. Land cover was the dominant source of variation in surface fluxes, with 50%–100% differences between fields planted in winter–spring versus fields planted in summer. Interannual variation was driven mainly by precipitation, which varied more than twofold between years. Peak aboveground biomass and growing season …


Recasting Dilemma Zone Design As A Marginal Cost-Benefit Problem, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta Jan 2007

Recasting Dilemma Zone Design As A Marginal Cost-Benefit Problem, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta

Department of Civil and Environmental Engineering: Faculty Publications

One control objective at high-speed isolated intersections is to provide safe phase transition by minimizing the occurrence of high-speed vehicles in the dilemma zone before the phase is terminated. An upper limit for extending the green (maximum green time) is used to avoid an indefinite extension of the main-street green. Currently, the maximum green times are chosen by using engineering judgment. This approach does not explicitly consider the trade-offs between safety and delay and hence often results in both unsafe and inefficient performance at the intersection under medium to heavy traffic volumes. The dilemma problem is recast as one of …


Limitations Of Simultaneous Gap-Out Logic, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta Jan 2007

Limitations Of Simultaneous Gap-Out Logic, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta

Department of Civil and Environmental Engineering: Faculty Publications

The current practice of specifying simultaneous gap-out logic places constraints on signal controller logic. These constraints cannot be achieved under high traffic flow conditions, and degraded signal efficiency and dilemma zone protection often result. This study documents the phenomenon described above with set-back detectors at an instrumented intersection in Noblesville, Indiana, and characterizes the problem of dilemma zone protection as being traffic-volume dependent, a factor that should be carefully considered before the simultaneous gap-out logic is applied. Implementation of simultaneous gap-out logic led to max out ranging from 3.5% to 40% of cycles per hour during peak traffic flow periods …


Event-Based Data Collection For Generating Actuated Controller Performance Measures, Edward J. Smaglik, Anuj Sharma, Darcy M. Bullock, James R. Sturdevant, Gary Duncan Jan 2007

Event-Based Data Collection For Generating Actuated Controller Performance Measures, Edward J. Smaglik, Anuj Sharma, Darcy M. Bullock, James R. Sturdevant, Gary Duncan

Department of Civil and Environmental Engineering: Faculty Publications

Cycle-by-cycle data have been shown to be effective in the analysis of a signalized intersection with measures of effectiveness such as volume-to-capacity ratios, arrival type, and average vehicular delay. Currently, actuated traffic controllers are unable to store vehicle counts and vehicle occupancy in cycle-by-cycle bins, requiring extra equipment and personnel to collect data in these bins. The objective of this research was to develop an integrated general purpose data collection module that time stamps detector and phase state changes within a National Electrical Manufacturers Association actuated traffic signal controller and uses those data to provide quantitative graphs to assess arterial …


Vacuum Ultraviolet Optical Analysis Of Spin-Cast Chitosan Films Modified By Succinic Anhydride And Glycidyl Phenyl Ether, W. H. Nosal, D. W. Thompson, T. E. Tiwald, S. Sarkar, Anuradha Subramanian, John A. Woollam Jan 2007

Vacuum Ultraviolet Optical Analysis Of Spin-Cast Chitosan Films Modified By Succinic Anhydride And Glycidyl Phenyl Ether, W. H. Nosal, D. W. Thompson, T. E. Tiwald, S. Sarkar, Anuradha Subramanian, John A. Woollam

John A. Woollam Publications

Optical properties of spin-cast chitosan films were determined in the vacuum ultraviolet (VUV) through visible regions of the spectrum using spectroscopic ellipsometry. The onset of absorption in the ultraviolet was determined for chitosan films modified with succinic anhydride (SA) and glycidyl phenyl ether (GPE). This absorption was accounted for by including Gaussian and Tauc– Lorentz shaped oscillators in the optical model. VUV through visible optical constants were determined for these modified films, as well as for immunoglobulin G (IgG) attached to GPE-modified samples. Several resonant oscillator structures exhibit greatly differing oscillator parameters for the as-deposited, as well as SA-and GPE-modified …


An Investigation Of Planar Monopole Antennas For Modern Portable Applications, Jonathan Arthur Evans Jan 2007

An Investigation Of Planar Monopole Antennas For Modern Portable Applications, Jonathan Arthur Evans

Doctoral

Current trends in portable and mobile communications are towards greater numbers of different systems often with wider bandwidths, operating within a single device. Antenna systems for these devices need to be capable of operating over a wide frequency range or multiple frequency bands, typically between 900MHz and 6GHz (e.g. GSM, IMT-2000, Wi-Fi and WiMax). Portable and mobile applications also require antennas to be optimised with respect to radiation pattern, efficiency and physical size. A greater understanding of the characteristics and design challenges of broadband and multi-band antennas forms the core motivation of this work. The antennas developed as part of …


Integrating It-Enabled Social Networks With Transaction Cost Economics And The Resource Based View Of The Firm, Ganesh D. Bhatt, Jatinder N. D. Gupta, Sushil K. Sharma Jan 2007

Integrating It-Enabled Social Networks With Transaction Cost Economics And The Resource Based View Of The Firm, Ganesh D. Bhatt, Jatinder N. D. Gupta, Sushil K. Sharma

Journal of International Technology and Information Management

Prior research has mostly focused on transaction cost economics (TCE) to interpret the effect of information systems (IS) on organizational governance structures. A TCE based approach predicts that information technology (IT) will lead to increased use of electronic markets to coordinate economic transactions from electronic hierarchies. However, there is contradictory evidence in the literature regarding the rise and importance of cooperative relationships, joint ventures, and value-added partnerships integrated through information systems. To reconcile these contradictions, this paper analyzes the effect of IT on governance structures based on the TCE, social network theory, and the resource based view (RBV) of the …

Internet Entrepreneurship And Economic Growth, Gerald V. Post, John F. Pfaff Jan 2007

Internet Entrepreneurship And Economic Growth, Gerald V. Post, John F. Pfaff

Journal of International Technology and Information Management

This paper looks at national attempts to promote economic growth through the Internet. Growth can be driven through service exports or internally through increased service transactions and fostering entrepreneurship. India is often held as an example of service exports, but economic statistics show that India might not be a good example for other nations because net service trade is negative and wages have been economically distorted. Ultimately, developing nations need to find internal growth models. Internal growth could be driven though increased consumption due to improved information, or increased investment expenditures from infrastructure investments.

Comparing The Prioritization Of Erp System Effectiveness Measures By Organizational Actors: A Focus On It Professionals And Business Managers, Princely Ifinedo

Journal of International Technology and Information Management

Modern organizations adopt Enterprise Resource Planning systems (ERP) to integrate their organizational data resources into unified systems. Researchers tend to concentrate on ERP implementation issues with only a handful studying ERP system effectiveness or success in adopting organizations. In fact, none has studied how key organizational actors prioritize or rank relevant measures or items related to the effectiveness of such systems. This study is designed to fill this gap in research as it aims at investigating how two organizational stakeholder groups, i.e. information technology (IT) professionals and business managers prioritize relevant measures related to ERP systems effectiveness. Using surveys in …

Improving Credit Card Operations With Data Mining Techniques, Malini Krishnamurthi Jan 2007

Improving Credit Card Operations With Data Mining Techniques, Malini Krishnamurthi

Journal of International Technology and Information Management

Consumer credit is ubiquitous and lending poses credit risk – the risk of economic loss due to the failure of a borrower to repay according to the terms of his or her contract with the lender. And so, managing credit risk entails estimating the potential ability of borrowers to repay their debts. Researchers have sought to identify factors that contribute to consumer risk, by using quantitative models. However, the presence of data mining techniques to identify credit risk cannot be ignored. There is a paucity of research to demonstrate the use of data mining techniques in this context, and such …


Internet Industry Competition Dynamics: Peering Limitations, Exposure, And Counter Strategies, Seungjae Shin, Jack E. Tucci Jan 2007

Internet Industry Competition Dynamics: Peering Limitations, Exposure, And Counter Strategies, Seungjae Shin, Jack E. Tucci

Journal of International Technology and Information Management

The Internet industry is vertically integrated with Internet Backbone Providers (IBPs) and Internet Service Providers (ISPs.) Although there are many ISPs and IBPs in each stream, both markets are considered independent oligopolies in that there are a few dominant competitors in each market. It is generally accepted that the Internet industry structure has evolved into a four-tier hierarchical structure. The synergistic and codependent nature of the Internet industry is the key element in understanding the competitive environment in which both IBP’s and ISP’s cooperate. Peering is an efficient way to exchange traffic freely within the access tier, nevertheless competitive constraints …
