Tillage System Effects On Upland Cotton Yield and Development In Virginia
Identifying the proper tillage system which provides the best agronomic benefits for cotton production in the coastal plain soils of Virginia was the basis for this research. Strip-tillage was evaluated from 2015-2016 on-farm to determine the effects of annual and biennial treatments on plant …

Geophysical characterization of onsite wastewater treatment system effects on groundwater quality, eastern North Carolina
Onsite wastewater treatment systems (OWS) are a potential non-point source of pollution that can result in water quality degradation in groundwater and surface water. Locating OWS wastewater plumes in the subsurface often requires extensive site instrumentation and monitoring. The application of …

Lactoperoxidase System Effects on Escherichia Coli K-12 in the Manufacture of a High Moisture and High pH Cheese (Queso Fresco)
<p><strong>The lactoperoxidase system, a naturally occurring antibacterial system in bovine milk, was evaluated as an additional food safety hurdle in a cheese that can support the growth of pathogenic microorganisms. Lactoperoxidase is not completely inactivated at pasteurization temperatures; …

Examining evidence for a protective occupational exposure limit for inhalable manganese dust below which there are no adverse subclinical nervous system effects
… inhalable manganese dust and subclinical nervous system outcomes amongst workers in a South African manganese smelter with a view to identifying any exposure threshold below which adverse effects do not occur.

Studies of Electron Traps in Gallium Arsenide and Gallium Arsenide Phosphide by Deep Level Transient Spectroscopy
System effects and data analysis for deep level transient spectroscopy (DLTS) have been examined and applied to study the deep levels in the GaAs-GaP system.

Reconsidering Composite Action on Strength of Wood Roof Systems
… (PV) modules on existing wood roof framing systems are considered. Often, existing roofs are inadequate to resist even current minimum design loads, much less the extra weight of PV modules. Rather than requiring expensive retrofits, it is desired to bring these under-strength roofs into …

Detecting Pulsars with Neural Networks
… radio-frequency interference (RFI) and observing-system effects. New observing systems provide higher bandwidths, higher data volumes and greater overall sensitivity (also to RFI), which further enhances these challenges. <br /><br /> A novel approach for the analysis of pulsar search data is …

Integrating lean principles in automotive product development : breaking down barriers in culture and process
… of transitioning to lean can be illuminated. The system effects of the barriers and inhibitors are also described using system dynamics. Finally, conclusions are developed in order to guide the company in its quest to become lean in product development and throughout the entire enterprise.

Estimation of Required Restraint Forces in Z-Purlin Supported, Sloped Roofs Under Gravity Loads
… restraint forces in Z-purlin supported roof systems under gravity loads are in Section D3.1 of the 1996 AISI Cold-Formed Specification. The design equations contained in these provisions are empirical and based on statistical analysis. They were developed using elastic stiffness models of …

Habitat driven responses of reef fish: temporal change, niche partitioning and selection
… dramatically in response to many stressor-driven effects. The change in turn threatens the associated fish communities relying on their maintenance for habitat provision. At present, a much better understanding of the interaction between changing habitats and the associated fish is necessary. To …

Brachypodium distachyon as a genetic model pathosystem to study resistance against fungal pathogens of small grain cereals
… (Bd) has the potential to serve as a model pathosystem relevant to small-grain cereals. Chapter 3 provides evidence of compatibility between Bd and the main causal agents of FHB and shows that symptom development mirrors closely that in wheat. Natural variation in disease resistance exists among …

Stimolazione da etanolo del sistema dopaminergico mesolimbico: ruolo dell'acetaldeide
… substance, may actually mediates the reinforcing effects of ethanol (EtOH) (1). Accordingly, in rodents ACD is self-administred and stimulates the firing of Ventral Tegmental Area (VTA) mesolimbic dopaminergic neurones (2,3). Moreover, recent data show that ACD blockade by sequestration with …

Analysis and modeling of the effects of reflection induced noise on the performance of fiber optic communication systems
… discontinuities in fiber optic transmission systems are known to cause deleterious effects. Non-negligible return losses associated with connectors and splices in present day systems cause intermittent error bursts and bit-error-rate floors in gigabit per second systems. These are attributed …

Multisystem Effects of Mold Inhalation: A Convergence on the Central Nervous System
… spore concentrations are unregulated. While the effects of mold exposure on certain respiratory diseases are well established, little is known about how inhaled mold affects extra-respiratory disease. Mold exposure is associated with central nervous system (CNS) symptoms in humans, but very …

Experimental Determination of Required Lateral Restraint Forces for Z-Purlin Supported, Sloped Metal Roof Systems
… forces in Z-purlin supported, sloped metal roof systems under gravity loads. A proposed prediction equation, relying heavily on engineering principles, has been developed because the current provisions in the specification are empirical and based on statistical analysis. The provisions treat roof …
