Journey From Black To Pink Gums: Management Of Melanin Induced Physiological Gingival Hyper Pigmentation, Huma Farid, Muhammad Saad Shinwari, Farhan Raza Khan, Farzin Tanwir

Department of Surgery Docs

Abstract

Smile is an expression of happiness, self-confidence, kindness and beauty. Along with teeth and lips, gingiva is also a vital component of smile. Melanin induced gingival hyper pigmentation may appear un-aesthetic especially when it is associated with high smile line, upper anterior labial segment and is uneven in appearance. It affects individuals from all races. Generally, it is believed that melanin induced gingival hyper pigmentation is confined to individuals from dark races. But studies have shown that Iranian, Indian, Italian, Arabian, Greek. German, French, Japanese, Chinese, Jewish, Thai, Malaysian and other ethnic groups also display clinical gingival pigmentation.1 Gingival …

Outcomes Of An Evidence-Based, Data Driven-Model Fieldwork Experience For Occupational Therapy Students, Amy P. Carroll, E. Adel Herge, Lindsay Johnson, Roseann C. Schaaf

Department of Occupational Therapy Faculty Papers

Over the past decade, there has been an increased emphasis on evidence-based practice (EBP) and the use of outcome measurement in clinical practice, however, the implementation of evidence into practice remains challenging and irregular. During fieldwork, students often experience a disconnect between the emphasis on EBP in the classroom and lack of use in the clinic. Recognizing the need to develop high-quality, evidence-based and data-driven models of practice for student training, we partnered with local fieldwork educators to develop an innovative program that guides students and simultaneously trains fieldwork educators (FWE) in the use of a systematic data driven decision …

Making Ritual Strange: The Temple Cult As The Foundation For Tannaitic Discourse On Idolatry, Avram R. Shannon

Faculty Publications

This article examines the Tannaitic conception of the worship of avodah zarah. The term is commonly translated as “idolatry,”but the definition of what constitutes worship of avodah zarah, in m. Sanh. 7:6, is based on a more nuanced notion than simply worship of foreign gods. For the Sages of the Mishnah, worship of avodah zarah involved misuse of objects and rituals associated with the Temple cult, which constituted a betrayal of covenantal loyalty. This means that although the rabbinic laws against the worship of avodah zarah were based on the biblical prohibitions against worshiping other gods, the actual …

Controlled Manipulation Of Floating Objects On Deformed Fluid Interfaces And Conditions For Stable Equilibria, Jose M. Carballo, Qi Ni, Jose Vasquez, Nathan B. Crane

Faculty Publications

At the millimeter scale, interactions between floating and semi-immersed objects are significant. The local curvature of the interface is modified by the weight/buoyancy forces of floating objects, and by the surface properties of semi-immersed objects. The curvature changes generate attractive (or repulsive) interactions between floating parts, and semi-immersed objects. This work demonstrates how electrowetting can manipulate these interactions in order to position, align, assemble and transport parts attached to the fluid interface. This demonstrates one way in which fluid interfaces can provide an alternative to standard pick and place technology for part positioning/assembly. Typically, the part/rod forces are purely attractive …

History Of The Taipei Temple, John Hilton Iii

Faculty Publications

MANY PRISONERS SUFFERED at the Taihoku Prison in Taipei, Taiwan, during World War II. Yet, less than two decades later, The Church of Jesus Christ of Latter-day Saints purchased a portion of this land and transformed it from a desolate site into a warm and inviting chapel where Latter-day Saints sought to bring their friends. Elder Gordon B. Hinckley dedicated it on October 16, 1966. Fewer than five thousand members resided in Taiwan at the time. In 1984, Hinckley returned to the same plot of land to dedicate a temple adjacent to the chapel. During one of his addresses, he …

Conceptualizing The Neurobiology Of Non-Suicidal Self-Injury From The Perspective Of The Research Domain Criteria Project, Scott R. Braithwaite, Melinda Westlund Schreiner, Bonnie Klimes-Dougan, Erin D. Begnel, Kathryn R. Cullen

Faculty Publications

Non-suicidal self-injury (NSSI) commonly starts in adolescence and is associated with an array of negative outcomes. Neurobiological research investigating NSSI is in its early stages and most studies have examined this behavior within the context of specific diagnoses. However, the Research Domain Criteria (RDoC) initiative encourages researchers to examine brain-behavior relationships across diagnoses. This review on the neurobiology associated with NSSI is organized using the domains proposed by RDoC: Negative Valence, Positive Valence, Cognitive, Social Processes, and Arousal/Regulatory Systems. Evidence of neurobiological anomalies is found in each of these domains. We also propose future research directions, especially in regard to …

Toxocara Seroprevalence And Associated Risk Factors In The United States, Bruce L. Brown, Andrew N. Berrett, Lance D. Erickson, Shawn D. Gale, Allison Stone, Dawson W. Hedges

Faculty Publications

Caused by the parasitic nematodes Toxocara canis and cati, toxocariasis in humans can result in covert toxocariasis, ocular toxocariasis, visceral larval migrans, and neurotoxocariasis. A common infection, toxocariasis exposure varies widely within and between countries, with a previous estimate of Toxocara seroprevalence using data from 1988 to 1994 in the United States of approximately 13%. Age, poverty, sex, educational attainment, ethnicity, and region have been associated with Toxocara seroprevalence. In this study, we sought to determine the seroprevalence of and factors associated with Toxocara seropositivity in the United States using data from the National Health and Nutrition Examination Survey from …

The Role Of Contextual Frequency In The Articulation Of Initial /F/ In Modern Spanish: The Same Effect As In The Reduction Of Latin /F/?, Earl K. Brown, Matthew C. Alba

Faculty Publications

The acoustic energy of 996 tokens of word-initial /f/ in the speech of 38 speakers of Mexican Spanish was analyzed. The results suggest that the frequency with which words occur in phonological contexts favorable to reduction (Frequency in a Reducing Context or FRC) conditions the reduction of /f/, even after taking into account the immediate phonological context. Despite this, it is also found that the conditioning effect of FRC is less robust than the influence of the immediate phonological context, thus confirming the preeminence in these data of the online articulatory factors in comparison to the usage-based frequency factors.

Kinship And The Self-Organization Of Exchange In Small-Scale Societies, James R. Allison

Faculty Publications

Circulation of material goods is common in small-scale societies. Even where exchange is not coordinated above the level of the household, goods produced in one area are consistently conveyed to distant settlements. Numerous ethnographic studies demonstrate that exchange transactions are common among kin, and that the circulation of goods in small-scale societies is structured by kinship ties. From an individual’s point of view, the number of kinfolk available to exchange with and where they live strongly affect access to nonlocal goods. This paper explores the interrelationships among kin networks, settlement organization, and exchange using agent-based modeling, ethnographic studies, and archaeological …

Agent-Based Modelling Of The Relationships Among Kinship, Residence, And Exchange, James R. Allison

Faculty Publications

In the North American Southwest, archaeological research has documented ceramic exchange networks in which spatially proximate households in consumer communities have greatly varying amounts of imported pottery. This paper uses agent-based modelling to gain insight into the processes responsible for these distributions. The agent-based model used here tracks kinship ties among agents representing individuals who give birth, marry, co-reside with spouses, and exchange things in a virtual landscape filled with small settlements of up to a few hundred individuals. Exchange of goods in the model flows through the kinship networks. The results suggest that the differential distribution of goods among …

Sourcing Basalt From The Santiago Quarry In Chihuahua, Mexico Using Xrf, Michael T. Searcy, Todd Pitezel, Eric Christiansen

Faculty Publications

During survey in 2013, we identified the only known vesicular basalt quarry in the Casas Grandes region in northwestern Chihuahua, Mexico. Using XRF, we analyzed basalt from the Santiago Quarry and compared the results to the chemical characterization of formal tools (mostly mano and metate fragments) recovered at the site of Paquimé in order to determine if this quarry was one of the sources exploited by prehistoric stoneworkers during the Medio period (AD 1200–1450).

Improving Sensitivity Of Electrochemical Sensors With Convective Transport In Free-Standing, Carbon Nanotube Structures, Benjamin J. Brownlee, Kevin M. Marr, Jonathan C. Claussen, Brian D. Iverson

Faculty Publications

High-aspect-ratio, porous membrane of vertically-aligned carbon nanotubes (CNTs) were developed through a templated microfabrication approach for electrochemical sensing. Nanostructured platinum (Pt) catalyst was deposited onto the CNTs with a facile, electroless deposition method, resulting in a Pt-nanowire-coated, CNT sensor (PN-CNT). Convection mass transfer enhancement was shown to improve PN-CNT sensor performance in the non-enzymatic, amperometric sensing of hydrogen peroxide (H₂O₂). In particular, convective enhancement was achieved through the use of high surface area to fluid volume structures and concentration boundary layer confinement in a channel. Stir speed and sensor orientation especially influenced the measured current in …

Extending The Upper Temperature Range Of Microchip Gas Chromatography Using A Heater/Clamp Assembly, Abhijit Ghosh, Jacob E. Johnson, Johnathan G. Nuss, Brittany A. Stark, Aaron R. Hawkins, Luke T. Tolley, Brian D. Iverson, H. Dennis Tolley, Milton L. Lee

Faculty Publications

Miniaturization of gas chromatography (GC) instrumentation is of interest because it addresses current and future issues relating to compactness, portability and field application. While incremental advancements continue to be reported in microchip GC, the current performance is far from acceptable. This lower performance compared to conventional GC is due to factors such as pooling of the stationary phase in corners of non-cylindrical channels, adsorption of sensitive compounds on incompletely deactivated surfaces, shorter column lengths and less than optimum interfacing to injector and detector. In this work, a microchip GC system was developed that solves the latter challenge, i.e. microchip interfacing …

A Continuous Time Model Of Centrally Controlled Motion With Random Switching Terms, J. C. Dallon, L C. Despain, E J. Evans, C P. Grant, Willaim V. Smith

Faculty Publications

This paper considers differential problems with random switching, with specific applications to the motion of cells and centrally coordinated motion. Starting with a differential-equation model of cell motion that was proposed previously, we set the relaxation time to zero and consider the simpler model that results. We prove that this model is well-posed, in the sense that it corresponds to a pure jump-type continuous time Markov process (without explosion). We then describe the model's long-time behavior, first by specifying an attracting steady-state distribution for a projection of the model, then by examining the expected location of the cell center when …

Racial Discrimination And Psychological Health Among Polynesians In The U.S., Kawika Allen, Hokule'a Conklin, Davis K. Kane

Faculty Publications

There is a dearth of research on the mental health of Polynesians residing in the United States. The aims of this study were to examine experiences of racial discrimination, self-esteem, trait anger, satisfaction with life, and psychological well-being among 628 Polynesians (e.g., Native Hawaiian, Tongan, Samoan, Fijian, Tahitian, Maori; 60% women (n 378) and 40% men (n 249); mean age 28.7). Method: Measures were administered through an online survey to 628 Polynesians residing in the United States. Comparison analyses between men and women, correlations, and path analyses were analyzed for this Polynesian sample. Results: Polynesian women showed higher levels of …

The Ancient Doctrine Of The Two Ways In The Book Of Mormon, Noel B. Reynolds

Faculty Publications

Consistent with their preexilic Hebrew Bible predecessors, the Book of Mormon prophets taught a version of the Two Ways doctrine that featured (1) invitations to repentance defined as turning or returning to God’s way, (2) the context of the Abrahamic covenant, (3) the blessings and cursings that would come from obedience or disobedience, and (4) the contrast of the path of righteousness that leads to life with the path of evil that leads to death. But this analysis has also produced a number of expansions or refinements of the Two Ways doctrine that are not reflected in biblical treatments of …

Family Resource Allocation After Firstborns Leave Home: Implications For Secondborns’ Academic Functioning, Alexander C. Jensen Phd, Shawn D. Whiteman, Julia M. Bernard, Susan M. Mchale

Faculty Publications

This study assessed secondborn adolescents’ perceptions of changes in the allocation of family resources following their firstborn siblings’ departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns’ academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase …

Do Muscle Strength Imbalances And Low Flexibility Levels Lead To Low Back Pain? A Brief Review, Cassio Victora Ruas, Adriane Vieira

Research outputs 2014 to 2021

Chronic low back pain (CLBP) has been related to hips, trunk and spine strength imbalances and/or low flexibility levels. However, it is not clear if the assessment and normalization of these variables are effective for prevention of low back pain (LBP) episodes and rehabilitation of patients with CLBP. This brief review explored studies that have associated hip, trunk and spine strength imbalances and/or low flexibility levels to LBP episodes or CLBP condition. Fourteen studies were selected by accessing PubMed and Google Scholar databases. Collectively, the selected studies demonstrate that trunk eccentric/concentric and flexion/extension strength imbalances may be associated with CLBP …

Modeling Effects Of Annealing On Coal Char Reactivity To O2 And Co2, Based On Preparation Conditions, Troy Michael Holland, Sham Bhat, Peter Marcy, James Gattiker, Joel D. Kress, Thomas H. Fletcher

Faculty Publications

Oxy-fired coal combustion is a promising potential carbon capture technology. Predictive computational fluid dynamics (CFD) simulations are valuable tools in evaluating and deploying oxyfuel and other carbon capture technologies, either as retrofit technologies or for new construction. However, accurate predictive combustor simulations require physically realistic submodels with low computational requirements. A recent sensitivity analysis of a detailed char conversion model (Char Conversion Kinetics (CCK)) found thermal annealing to be an extremely sensitive submodel. In the present work, further analysis of the previous annealing model revealed significant disagreement with numerous datasets from experiments performed after that annealing model was developed. The …

Model For The Evolution Of Pore Structure In A Lignite Particle During Pyrolysis. 2. Influence Of Cross-Linking Reactions, Molten Metaplast, And Molten Ash On Particle Surface Area, He Yang, Thomas H. Fletcher, Sufen Li, Haoquan Hu, Lijun Li

Faculty Publications

A model for the evolution of the pore structure in a lignite particle during pyrolysis was established previously based on the chemical percolation devolatilization (CPD) model, using coal polymer network parameters to calculate the surface area and porosity of the particle. In this paper, to get the accurate surface area of coal particle at high pyrolysis temperature, the previous model was improved by considering the effects of cross-linking reactions, molten Metaplast, and ash. The good agreement of the predicted surface area with experiments at temperature below 1200 K in the previous model is maintained, and model accuracy is improved at …

Comprehensive Model Of Single Particle Pulverized Coal Combustion Extended To Oxy-Coal Conditions, Troy Michael Holland, Thomas H. Fletcher

Faculty Publications

Oxy-fired coal combustion is a promising potential carbon capture technology. Predictive CFD simulations are valuable tools in evaluating and deploying oxy-fuel and other carbon capture technologies either as retrofit technologies or for new construction. However, accurate predictive simulations require physically realistic submodels with low computational requirements. In particular, comprehensive char oxidation and gasification models have been developed that describe multiple reaction and diffusion processes. This work extends a comprehensive char conversion code (CCK), which treats surface oxidation and gasification reactions as well as processes such as film diffusion, pore diffusion, ash encapsulation, and annealing. In this work several submodels in …

Semi-Empirical Model For Fire Spread In Shrubs With Spatially-Defined Fuel Elements And Flames, Dallan Prince, Chen Shen, Thomas H. Fletcher

Faculty Publications

A semi-empirical model was developed which forms shrub geometries from distinct fuel elements (e.g. leaves) and describes flame spread from element to element. Ignition, flame growth and flame decay patterns were based on combustion data of single leaves. Extension of the model to various heating conditions was achieved by scaling the flame growth parameters using physics-based heat transfer models. The resulting model offers a novel approach to examine fire spread and to explicitly describe both distinct fuel elements and fire behavior. This approach balances computational speed and modeling detail while providing a unique perspective into fire spread phenomena. Comparisons of …
