Can Cover Crops Reduce Leafhopper Abundance In Vineyards?, Kent M. Daane, Michael J. Costello

Horticulture and Crop Science

In 3 of 4 vineyards we studied, late-season leafhopper density was lower on vines in cover cropped plots than in plots with no cover crops. However, the level of leafhopper reduction (about 15%) was rarely economically important and the mechanisms leading to reduction were not clear. For example, there were few differences in the number of leaf hopper predators or parasitoids on the vines in cover cropped versus no cover plots. However, there were significant between-treatment differences in vine growth. Plots with seasonwide maintenance of a cover crop and resident grasses had a reduction in vine vigor. Lower vine vigor …

Rapid Detection Of Listeria Monocytogenes In Dairy Samples Utilizing A Pcr-Based Fluorogenic 5′ Nuclease Assay, T. Cox, C. Frazier, J. Tuttle, S. Flood, L. Yagi, C. T. Yamashiro, R. Behari, C. Paszko, R. J. Cano

Biological Sciences

The presence of Listeria monocytogenes as a dairy food contaminant is a lethal threat to dairy industrialists; therefore, products tainted with L. monocytogenes must be quickly detected and removed from production. This fluorogenic PCR-based assay was developed to rapidly detect L. monocytogenes contamination in dairy samples before a final product is distributed. The detection method employed uses a PCR primer pair and a fluorogenic TaqMan probe which bind to a region of a virulence determinant gene specific to L. monocytogenes. As the DNA target is amplified, the 5′ nuclease activity of Taq DNA polymerase hydrolyzes the internal fluorogenic probe …

Positive Behavioral Support: Strategies For Teachers, Michael B. Ruef, Cindy Higgins, Barbara J.C. Glaeser, Marianne Patnode

Graduate Studies in Education

Positive behavioral support (PBS) is a comprehensive, research-based proactive approach to behavioral support that endeavors to generate comprehensive change for students with challenging behavior. It involves identifying the purpose of challenging behavior, teaching appropriate alternative responses that serve the same purpose as the challenging behavior, consistently rewarding positive behaviors and minimizing the rewards for challenging behavior, and minimizing the physiological, environmental, and curricular elements that trigger challenging behavior. Proven PBS strategies include altering the classroom environment, increasing predictability and scheduling, increasing choice making, adapting the curriculum, appreciating positive behaviors, and teaching replacement skills. Relevant sources for those interested in implementing …

Navier-Stokes Analysis Of Lift-Enhancing Tabs On Multi-Element Airfoils, Paul G. Carrannanto, Bruce L. Storms, James C. Ross, Russell M. Cummings

Aerospace Engineering

The flow over multi-element airfoils with flat-plate lift-enhancing tabs was numerically investigated. Tabs ranging in height from 0.25 to 1.25% of the reference airfoil chord were studied near the trailing edge of the main element. The two-dimensional numerical simulation employed an incompressible Navier–Stokes solver using a structured, embedded grid topology. The effects of various tabs were studied at a constant Reynolds number on a two-element airfoil with a slotted flap. Both computed and measured results indicated that a tab in the main-element cove improved the maximum lift and lift-to-drag ratio relative to the baseline airfoil without a tab. Computed streamlines …

Whey Protein Edible Film Structures Determined By Atomic Force Microscope, L.E. Lent, L. S. Vanasupa, P. S. Tong

Dairy Science

Atomic force microscopy was used to study edible films produced from whey proteins. The films were imaged under ambient conditions with no special sample preparation. Low resolution imaging of areas from 10 μm to 150 μm on a side was performed in the contact mode. Higher resolution scans of 350 nm to 2,700 nm required use of the noncontact imaging mode. Features about the same size as the primary protein in whey, beta-lactoglobulin (7 nm), were identified in the film samples. Molecular aggregates in the range of 1 μm, reported in other studies using transmission electron microscopy of whey protein …

A Neural Network Pruning Algorithm With Embedded Gradient-Conjugate Training For The Identification Of Large Flexible Space Structures, Xiao-Hua Yu

Electrical Engineering

The choice of network dimension is a fundamental issue in the design of artificial neural networks. A larger neural network is powerful for solving problems while a smaller neural network is always advantageous in real-time environment where speed is crucial. In this paper, a network pruning algorithm with embedded gradient-conjugate training is investigated and applied to the identification of a large flexible space structure. Computer simulation results show that this approach can dramatically reduce the size of neural network while maintaining compatible identification accuracy.

Use Of Polyurethane Material Models For Simulating Leg-Form Impact In Different Explicit Finite Element Codes, Joe Hassan, Peter Schuster, G. Frederick

Mechanical Engineering

Compressible plastic foams are used throughout the interior and bumper systems of modern automobiles for safety enhancement and damage prevention. Consequently, modeling of foams has become very important for automobile engineers. To date, most work has focused on predicting foam performance up to approximately 80% compression. However, in certain cases, it is important to predict the foam under maximum compression, or 'bottoming-out.' This paper uses one such case-a thin low-density bumper foam impacted by a pedestrian leg-form at 11.1 m/s-to investigate the 'bottoming-out' phenomenon. Multiple material models in three different explicit Finite Element Method (FEM) packages (RADIOSS, FCRASH, and LS-DYNA) …

Creating A Market Orientation, John C. Narver, Stanley F. Slater, Brian C. Tietje

Marketing

A market orientation is a business culture in which all employees are committed to the continuous creation of superior value for customers. However, businesses report limited success in developing such a culture. One approach to create a market orientation, the approach taken by most businesses, is the “programmatic” approach, an a priori approach in which a business uses education programs and organizational changes to attempt to implant the desired norm of continuously creating superior value for customers. A second approach is the “market-back” approach, an experiential approach in which a business continuously learns from its day-to-day efforts to create and …

Signal Monitoring Apparatus For Wavelength Divison Multiplexed Optical Telecommunication Networks, Dennis J. Derickson, Roger Lee Jungerman

Electrical Engineering

A detector array spectrometer simultaneously monitors wavelength, power, and signal-to-noise ratio of wavelength division multiplexed (WDM) channels in telecommunication networks. A spectrometer spatially separates signals from the WDM channels according to the channels' wavelengths. The separated signals are incident on an array of split-detectors that conforms to the spatial separation of the signals provided by the spectrometer. While the split-detectors are positioned to receive a signal from each WDM channel, a noise detector is positioned between adjacent split-detectors to measure noise. A common mode output from two halves of each split-detector indicates the power in a WDM channel, while a …

Collaborative Decision Support Systems For Facility Management, Arthur J. Chapman, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Agent-based collaborative decision support is a methodology of utilizing domain specific intelligent systems, interacting in a common environment, to partner with one or more human decision makers to reach a consensus solution to a complex problem. An example is the recently developed Collaborative Infrastructure Assessment Tool (CIAT) that provides a collaborative planning facility management tool in support of military pier and port management. This methodology is applicable to many similar dynamic facility management problems where the complexity of issues and the number of decision makers result in the need for domain specific agents, a common view of the data, and …
