Waveguiding Of Surface Phonon Polariton, Franklin Manene, Brian A. Lail, Edward C. Kinzel

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Metal losses lead to unacceptably low propagation lengths in THz and LWIR waveguides. While SPP based waveguides provide relatively good confinement and attenuation in the near-IR and visible these are insufficiently bound to the surface in the THz and LWIR. We study using surface phonon polaritons for waveguiding at these frequencies. An eigenmode approach was applied to model a hybrid waveguide structure at λ=10.6 μm. The results show that phonon-coupled hybrid waveguide of silicon carbide BCB and gold exhibit enhanced propagation length and confinement at LWIR. © 2013 IEEE.

The Limits Of Custom In Constitutional And International Law, Michael D. Ramsey

San Diego Law Review

This Article does not contend that arguments for extension of custom are illegitimate. Instead, it makes two more limited claims. First, there is an important difference between arguments from pure custom and arguments for the extension of custom, with the latter being more properly called common law arguments. Second, the legitimacy of common law arguments in some fields, especially constitutional law and international law, is substantially more problematic than the legitimacy of arguments from pure custom. The Article develops as follows. Part II sets out in greater detail the proposed distinction between arguments from pure custom and arguments for extension …

Achieving The Dream: Extending Immigration Reform To Administrative Case Closure, Tory E. Smith

San Diego Law Review

This Comment compares DACA to administrative case closure and argues that Congress or the President should grant employment authorization to individuals whose cases have been administratively closed. Part I describes the current interpretation of the employment authorization regulation and provides the background of administrative case closure. Part I highlights the disparate treatment that the regulation affords to undocumented immigrants facing deferred action and administrative closure—offering employment authorization to only deferred action recipients. Part II examines the history of deferred action in immigration cases and uses DACA as a framework to show how the scope of the employment authorization regulation should …

Effects Of Exposure To Abuse And Violence In Childhood On Adult Attachment And Domestic Violence In Women’S Same-Sex Relationships, Dawn M. Beatty

Seton Hall University Dissertations and Theses (ETDs)

ABSTRACT

There is an abundance of previous research proving that childhood abuse and adult domestic violence is an increasingly serious problem (Smith Slep, & O’Leary, 2005). However, while studies have shown that lesbian intimate battering occurs as frequently, if not more than, heterosexual domestic violence (Gosselin, [ARF1] 2003; Niolon, 2002), it remains understudied. Therefore, this study not only examines the relationship between childhood abuse and intimate lesbian violence but also secure and insecure attachment styles. Children who witness domestic violence or who are victims of emotional, physical, or sexual abuse are likely to repeat or engage in violent relationships later …

An Analysis On Soil Properties On Predicting Critical Hydraulic Gradients For Piping Progression In Sandy Soils, Tammy Jacobson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Piping is a form of internal erosion in which soil particles are eroded at a seepage exit location due to the forces imposed on the particles by seeping water. Laboratory testing was performed on a variety of soils in order to assess a correlation between unit weight, angle of internal friction, grain size, gradation, and void ratio and the critical hydraulic gradient at which piping initiates and progresses. A multi-variable regression analysis was used to form equations to predict critical hydraulic gradient based upon each of these soil parameters. Variations in the accuracy of these equations are thought to be …

Pyrolysis Of Acrylonitrile-Butadiene-Styrene (Abs) Under High Heat Flux Conditions, James R. Wilson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Acrylonitrile-butadiene-styrene (ABS) is a common industrial plastic that is widely used for structural and piping applications. Additionally, within the past decade ABS has become the most popular material used in a type of rapid prototyping known as fused- deposition modeling (FDM). Within the past three years, ABS plastic blends have also been investigated as a potential fuel for hybrid- and solid-propelled rocket systems, exhibiting promising results. Because the use of ABS as a rocket propellant is very recent, a pyrolysis database, describing how ABS will burn, at the temperatures and heating rates experienced by rocket systems does not exist.

Publications and Research

A growing number of studies are evaluating retinal progenitor cell (RPC) transplantation as an approach to repair retinal degeneration and restore visual function. To advance cell-replacement strategies for a practical retinal therapy, it is important to define the molecular and biochemical mechanisms guiding RPC motility. We have analyzed RPC expression of the epidermal growth factor receptor (EGFR) and evaluated whether exposure to epidermal growth factor (EGF) can coordinate motogenic activity in vitro. Using Boyden chamber analysis as an initial highthroughput screen, we determined that RPC motility was optimally stimulated by EGF concentrations in the range of 20-400ng/ml, with decreased stimulation …

Electrospinning Polymer Blends For Biomimetic Scaffolds For Acl Tissue Engineering, Vanessa Lizeth Garcia

Theses and Dissertations - UTB/UTPA

The anterior cruciate ligament (ACL) rupture is one of the most common knee injuries. Current ACL reconstructive strategies consist of using an autograft or an allograft to replace the ligament. However, limitations have led researchers to investigate tissue engineered grafts, known as scaffolds, through electrospinning. Scaffolds made of natural and synthetic polymer blends have the potential to promote cell adhesion while having strong mechanical properties. However, enzymes found in the knee are known to degrade tissues and affect the healing of intra-articular injuries. Results suggest that the natural polymers used in this study modify the thermal properties and tensile strength …

Implementing implantable sensors which are robust enough to maintain long term functionality inside the body remains a significant challenge. The ideal implantable sensing system is one which is simple and robust; free from batteries, telemetry, and complex electronics. We have developed an elementary implantable sensor for orthopaedic smart implants. The sensor requires no telemetry and no batteries to communicate wirelessly. It has no on-board signal conditioning electronics. The sensor itself has no electrical connections and thus does not require a hermetic package. The sensor is an elementary L-C resonator which can function as a simple force transducer by using a …

Tier 3 Intervention: Youth Courts, Ann O'Connor, Emily Moss, Jenna Strawhun, Reece L. Peterson

Department of Special Education and Communication Disorders: Faculty Publications

Conclusion

Youth courts represent a promising approach to developing youth involvement in diminishing juvenile delinquency and substance abuse, and as such, represent a useful approach to crime and violence prevention. As with conflict resolution education and peer mediation programs, the potential benefit of youth courts is two-fold. First, it has the possibility of diminishing youth crime and recidivism directly through the sanctions imposed and restorative practices used. Secondly, it may affect a wider group of teens through the skills, training and experiences of the youth volunteers. Based on the evaluation data to date, the youth court program appears to be …
