Evaluation Of Salmonella Biofilm Cell Transfer From Common Food Contact Surfaces To Beef Products, Rong Wong, David A. King, Norasak Kalchayanand

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Meat contamination by Salmonella enterica is a serious public health concern. Available data have suggested that biofilm formation at processing plants and contaminated contact surfaces might contribute to meat contamination. Because transfer from contact surfaces to food products via direct contact has been deemed the most common bacteria transmission route that can lead to contamination, we evaluated the effect of Salmonella biofilm forming ability, contact surface material, and beef surface tissue type on Salmonella biofilm transfer from hard surfaces to beef products. Salmonella biofilms developed on the common contact surfaces stainless steel (SS) and polyvinylchloride (PVC) were transferred consecutively via …

An Examination Of Positive Behavioral Interventions And Supports (Pbis) And Conscious Discipline As An Intervention To Challenging Behaviors In The Preschool Classroom, Jennifer Nelson

Graduate Teacher Education

In the field of early childhood education, there has been a growing concern over the number of challenging behaviors being displayed. To decrease the display of challenging behaviors, educators have been looking for positive strategies and supports to help manage the display of challenging behaviors such as Positive Behavioral Interventions and Supports (PBIS) (Carter, Van Norman, & Tredwell, 2011), and Conscious Discipline (Bailey, 2014). When managing the display of challenging behaviors, a shift has occurred from using negative discipline practices to implementing positive guidance approaches in early childhood (EC) classrooms (Carter et al., 2011). When educators teach the children what …

A Comparison Of The Effects Of Heat Therapy And Exercise Training On Vascular Function During Passive And Active Exercise, Taysom Erica Wallace

Theses and Dissertations

Recent evidence suggests that heat, a major byproduct of exercise, may be the mediator for many vascular adaptations that come from exercise. Thus, heat therapy that increases muscle temperature in a comparable way to exercise may be an advantageous alternative for enhancing cardiovascular health in individuals where treatment with exercise is either not possible or undesired. PURPOSE: Compare the effects of exercise and heat training on resistance artery function at rest and during exercise. METHODS: Thirty-five (18 female) healthy, untrained subjects completed a 6-week training program utilizing either high intensity knee extension (KE) exercise (40 min), localized heat therapy (pulsed …

This is the key issue of this thesis. In the first part, by studying …

Seedemu: The Seed Internet Emulator, Honghao Zeng

Theses - ALL

I studied and experimented with the idea of building an emulator for the Internet. While there are various already available options for such a task, none of them takes the emulation of the entire Internet as an important feature in mind. Those emulators and simulators can handle small-scale networks pretty well, but lacks the ability to handle large-size networks, mainly due to:

- Not being able to run many nodes, or requires very powerful hardware to do so,- Lacks convenient ways to build a large emulation, and - Lacks reusability: once something is built, it is very hard to re-use …

The eruptive activity of the Strawberry Rhyolites is currently constrained to span a period of about 2 million years, …

High-Resolution Cryo-Electron Microscopy Structure Of Photosystem Ii From The Mesophilic Cyanobacterium, Synechocystis Sp. Pcc 6803, Christopher J. Gisriel, Jimin Wang, Jinchan Liu, David A. Flesher, Krystle M. Reiss, Hao-Li Huang, Ke R. Yang, William H. Armstrong, M. R. Gunner, Victor S. Batista, Richard J. Debus, Gary W. Brudvig

Publications and Research

Photosystem II (PSII) enables global-scale, light-driven water oxidation. Genetic manipulation of PSII from the mesophilic cyanobacterium Synechocystis sp. PCC 6803 has provided insights into the mechanism of water oxidation; however, the lack of a highresolution structure of oxygen-evolving PSII from this organism has limited the interpretation of biophysical data to models based on structures of thermophilic cyanobacterial PSII. Here, we report the cryo-electron microscopy structure of PSII from Synechocystis sp. PCC 6803 at 1.93-Å resolution. A number of differences are observed relative to thermophilic PSII structures, including the following: the extrinsic subunit PsbQ is maintained, the C terminus of the …

Improved Bathymetry Leads To >4000 New Seamount Predictions In The Global Ocean – But Beware Of Phantom Seamounts!, C Yesson, Tb Letessier, A Nimmo-Smith, P Hosegood, As Brierley, M Hardouin, R Proud

School of Biological and Marine Sciences

Seamounts are important marine habitats that are hotspots of species diversity. Relatively shallow peaks, increased productivity and offshore locations make seamounts vulnerable to human impact and difficult to protect. Present estimates of seamount numbers vary from anywhere between 10,000 to more than 60,000. Seamount locations can be estimated by extracting large, cone-like features from bathymetry grids (based on criteria of size and shape). These predicted seamounts are a useful reference for marine researchers and can help direct exploratory surveys. However, these predictions are dependent on the quality of the surveys underpinning the bathymetry. Historically, quality has been patchy, but is …

Dissertations - ALL

This research project centered 16 former intergroup dialogue (IGD) students' narratives from in-depth qualitative interviews and explored the ways participants did and did not put their learning into action at least a full semester after IGD course completion. Narrative data were analyzed through the lens of the Cycle of Liberation (Harro, 2010) and student actions were categorized as intrapersonal (within self), interpersonal (with others), and systemic (with/for larger organized groups). Most participants stated that their IGD experiences were among the most influential of their college experience at the time of the interview. Often the influence of IGD echoed in the …

A Variable Stiffness Energy Dissipation Device For Vibration Control Of Steel Frames, Tie Zheng

Dissertations - ALL

Structures without energy dissipation devices rely primarily on plastic or inelastic deformations to dissipate energy from earthquakes. As a result, the amount of inelastic deformations and damage level will increase as the earthquake severity increases. However, structures equipped with energy dissipation devices are expected to experience less inelastic deformations and so their safety and integrity can be better preserved.In this research, a new device called the variable stiffness energy dissipation device is conceptualized and numerically studied. Using nonlinear time history analysis, results are obtained to illustrate the effectiveness of the proposed device in enhancing the seismic performance of shear and …

Investigation Of Lithium-Ion Battery Electrode Fabrication Through A Predictive Particle-Scale Model Validated By Experiments, Mojdeh Nikpour

Theses and Dissertations

Next-generation batteries with improved microstructure and performance are on their way to meet the market demands for high-energy and power storage systems. Among different types of batteries, Li-ion batteries remain the best choice for their high energy density and long lifetime. There is a constant but slow improvement in Li-ion batteries by developing new materials and fabrication techniques. However, further improvements are still needed to meet government and industry goals for cost, cycling performance, and cell lifetime. A fundamental understanding of particle-level interactions can shed light on designing new porous electrodes for high-performance batteries. This is a complex problem because …

Detecting Supraglacial Debris Thickness With Gpr Under Suboptimal Conditions, Alexandra Giese, Steven Arcone, Robert Hawley, Gabriel Lewis, Patrick Wagnon

Dartmouth Scholarship

The thickness of a supraglacial layer is critical to the magnitude and time frame of glacier melt. Field-based, short pulse, ground-penetrating radar (GPR) has successfully measured debris thickness during a glacier's melt season, when there is a strong return from the ice-debris interface, but profiling with GPR in the absence of a highly reflective ice interface has not been explored. We investigated the performance of 960 MHz signals over 2 km of transects on Changri Nup Glacier, Nepal, during the post-monsoon. We also performed laboratory experiments to interpret the field data and investigate electromagnetic wave propagation into dry rocky debris. …

Benzodiazepine Use And Dependence In Relation To Chronic Pain Intensity And Pain Catastrophizing, Emma Carnes Lape

Theses - ALL

Benzodiazepines (BZDs), a class of sedative-hypnotic drugs, are at the center of an emerging prescription drug crisis. From approximately 1995-2015, overdose deaths involving BZDs quadrupled and average dose equivalents more than tripled. Specific concern has centered on elevated rates of BZD use among individuals with chronic pain, given that BZDs are generally not indicated for pain management. Consistent with negative reinforcement and motivational models of substance use, desire for pain alleviation may be a salient motivator of BZD use, particularly as individuals commonly report using BZDs for negative affect alleviation. The present study tested cross-sectional associations between pain intensity and …

Mosque Architecture And Identity: A Study Of The Autochthonous Mosque In China, Yutong Ma

Graduate School of Architecture & Urban Design Theses & Dissertations

This thesis argues that an autochthonous mosque architecture exists in China, and this historical type adequately serves as a reference for contemporary mosque building in southeastern China in light of how it responded to the Chinese cultural and urban contexts. Many Hui Muslims and architects in this region refuse to consider historical mosque architecture built in traditional Chinese architectural style as their cultural references in constructing new mosques, as they believe that the traditional Chinese architectural language is insufficient to express their identity as Muslims. Instead, they prefer a collection of symbolic architectural elements to be used in mosque architecture …

A Portrait Of Postsecondary Stem Teaching: Examining The Roles Of Organizational Climate And Professional Identity, Sule Aksoy

Dissertations - ALL

Many empirical studies on the factors associated with the use of evidence-based instructional practices have examined the individual and contextual characteristics. However, little attention has been afforded to the role of context and practice on teacher identity. This dissertation consists of three-article style papers that examine the relationship between contextual factors, teacher identity, and instructional practices to fill this gap in the literature. Chapter 1 provides a deep understanding of organizational climate in STEM departments concerning teaching practices. Significant differences in organizational factors such as leadership, resources, and respect for teaching were found between graduate instructors and the faculty. Similarly, …

Buckling Patterns And Mechanics Of Thin Interfacial Polymer Films, Monica M. Ripp

Dissertations - ALL

Thin elastic solids are easily deformed and will readily collapse into complex buckling modes. They can also transition between distinct buckling modes when the confining forces evolve over time, forming a variety of robust and striking patterns. Here we explore how thin interfacial films and the buckling modes they present couple with evolving macroscopic forces and how multi-scale features of the systems give rise to patterns.

In the indentation of a circular film floating on a liquid bath three buckling modes arise: wrinkling, crumpling, and folding. This work shows that striking transitions between these states accompany four regimes in the …
