Comparison Of Coincident Rayleigh-Scatter And Sodium Resonance Lidar Temperature Measurements From The Mesosphere-Lower-Thermosphere Region, Leda Sox, Vincent B. Wickwar, Neal R. Criddle, Tao Yuan

All Physics Faculty Presentations

There are relatively few instruments that have the capabilities to make near continuous measurements of the mesosphere-lower-thermosphere (MLT) region. Rayleigh scatter and resonance lidars, particularly sodium resonance lidar, have been the two dominant ground-based techniques for acquiring mesosphere and MLT vertical temperature profiles, respectively, for more than two decades. With these measurements, the dynamics (gravity waves, tides) and long-term temperature trends (upper atmosphere cooling) of the MLT region can be studied. The Utah State University (USU; 41.7º N, 111.8º W) campus hosts a unique upper atmospheric observatory which houses both a high-power, large-aperture Rayleigh lidar and a sodium resonance Doppler …

Aggregation Characterization Of Wild-Type P53 And Six Common P53 Mutants, Taylor A. Arhar

Honors Thesis

P53 is a tumor suppressor protein, which functions in maintaining the cell cycle. When p53 loses its function, cells may multiply at an uncontrolled rate and form tumors. This loss of function is linked to over fifty percent of human cancers. This investigation aims to explore the possible link between p53 aggregation and tumorigenesis. There is a possibility that p53, especially in mutant form, will aggregate beyond its normal tetrameric conformation and lose its function, leading to tumor formation. Wild-type p53 and six mutants, R175H, R175C, R248Q, R248W, R273C, and R273H (six of the most common mutations found in human …

Adaptive Pi Control To Realize Sinusoidal Ripple Current Charging In Battery Charger Systems, Jen-Guey Chen

Master's Theses

This thesis proposes the adaptive PI gain control to regulate sinusoidal ripple current (SRC) in battery charger systems. The SRC charge method is suited for fast and efficient charging. Y.D Lee (2015) propose that SRC charge method can reduce the charging time, decrease the charging temperature and improve the charging efficiency by applying optimal frequency to charge the battery. In order to determine optimal frequency for charging, the swept frequency is required in SRC charge method. Therefore, in order to perform SRC charge approach, the battery charger systems have to be capable of handling swept frequency input and regulating high …

Isis, Boko Haram, And The Human Right To Freedom From Slavery Under Islamic Law, Bernard K. Freamon

Fordham International Law Journal

There is now a worldwide consensus on the firm existence of a human right to freedom from slavery. This consensus gives rise to what was thought to be an irrefutable argument that the right to be free from slavery is a jurisprudential universal, with no competent legal system or government able to deny its existence or permit derogation from its tenets. This argument is now being tested by the ideologies, policies, and actions of Muslim insurgencies in Iraq, Syria, and Nigeria, each claiming that the enslavement of non-believing combatants and war captives and slave trading in such persons is permitted …

Numerical Investigation Of Parameters Impacting The Wall Thickness Of Carbon Nanotubes Manufactured By Template-Based Chemical Vapor Deposition, Yashar Seyed Vahedein

Theses

Template-based chemical vapor deposition (TB-CVD) is a versatile technique for manufacturing carbon nanotubes (CNTs) or CNT-based devices for various applications. In this process, carbon is deposited by thermal decomposition of a carbon-based precursor gas inside the nanoscopic cylindrical pores of anodized aluminum oxide (AAO) templates to form CNTs. Experimental results show CNT formation in templates is controlled by TB-CVD process parameters, such as time, temperature and flow rate. Optimization of this process is done empirically, requiring tremendous time and effort. Moreover, there is a need for a more comprehensive and low cost way to characterize the flow in the furnace …

Iron-Dependent Gene Expression In Actinomyces Oris, Matthew P. Mulé, David Giacalone, Kayla Lawlor, Alexa Golden, Caroline Cook, Thomas Lott, Elizabeth Aksten, George A. O'Toole, Lori J. Bergeron

Dartmouth Scholarship

Actinomyces oris is a Gram-positive bacterium that has been associated with healthy and diseased sites in the human oral cavity. Most pathogenic bacteria require iron to survive, and in order to acquire iron in the relatively iron-scarce oral cavity A. oris has been shown to produce iron-binding molecules known as siderophores. The genes encoding these siderophores and transporters are thought to be regulated by the amount of iron in the growth medium and by the metal-dependent repressor, AmdR, which we showed previously binds to the promoter of proposed iron-regulated genes.

Monitoring Of Breathing Activity Using Smartphone-Acquired Signals, Bersain A. Reyes

Doctoral Dissertations

Respiratory rate (RR) and tidal volume (V_T) are two parameters that a breathing monitor should provide. Several techniques have been developed for monitoring these parameters in clinical and research settings. However, as being designed for such settings, they employ specialized devices that are not translated easily to everyday use due to their high costs, need for skilled operators, or limited mobility. Hence, there is still a lack of portable monitoring devices that can noninvasively estimate RR and V_T on a daily basis for the general population. Among V_T and RR monitoring methods, respiratory acoustical and noncontact …

Lagrangian Approach To Modeling The Biodynamics Of The Upper Extremity: Applications To Collegiate Baseball Pitching, Matthew J. Solomito

Doctoral Dissertations

Biomechanical modeling can provide information regarding movement patterns and allow for an improved understanding of injury mechanisms. Biomechanical models typically rely on Newtonian mechanics leading to computationally intensive models; however, an often overlooked means of solving these same modeling needs is to apply the Lagrangian approach. This approach allows for a more direct means of solving the equations of motion; leading to more accurate models of human motion. The purpose of this project was to create a Lagrangian based model of the upper extremity to describe joint kinematics and kinetics as well as muscle kinetics during complex motion tasks.

Dynamics Of Density Cavities Generated By Frictional Heating: Formation, Distortion, And Instability, M. D. Zettergren, J. L. Semeter, H. Dahlgren

Publications

A simulation study of the generation and evolution of mesoscale density cavities in the polar ionosphere is conducted using a time-dependent, nonlinear, quasi-electrostatic model. The model demonstrates that density cavities, generated by frictional heating, can form in as little as 90 s due to strong electric fields of ∼120 mV/m, which are sometimes observed near auroral zone and polar cap arcs. Asymmetric density cavity features and strong plasma density gradients perpendicular to the geomagnetic field are naturally generated as a consequence of the strong convection and finite extent of the auroral feature. The walls of the auroral density cavities are …

Evaluation Of The Crystalline Lens Gradient Refractive Index Using Laser Ray Tracing And Optical Coherence Tomography, Bianca Maceo Heilman

Open Access Dissertations

The human crystalline lens is a complex and intricate structure that continuously grows throughout our lifetime. The crystalline lens has a non-uniform distribution of protein concentrations which produces an optical gradient within the lens in both the optical and equatorial axes. This gradient refractive index is a unique property of the crystalline lens that significantly contributes to its optical power and aberrations. The objective of this dissertation is to gain a better understanding of the relationship between the crystalline lens shape, its non-uniform gradient refractive index, the lens optical power and aberrations, and their changes with accommodation and age. The …

Trm9-Catalyzed Trna Modifications Regulate Global Protein Expression By Codon-Biased Translation, Thomas J. Begley, Wenjun Deng, I. Ramesh Babu, Dan Su, Shanye Yin, Peter C. Dedon

Biological Sciences Faculty Scholarship

Post-transcriptional modifications of transfer RNAs (tRNAs) have long been recognized to play crucial roles in regulating the rate and fidelity of translation. However, the extent to which they determine global protein production remains poorly understood. Here we use quantitative proteomics to show a direct link between wobble uridine 5-methoxycarbonylmethyl (mcm⁵) and 5-methoxy-carbonyl-methyl-2-thio (mcm⁵s²) modifications catalyzed by tRNA methyltransferase 9 (Trm9) in tRNA^Arg(UCU) and tRNA^Glu(UUC) and selective translation of proteins from genes enriched with their cognate codons. Controlling for bias in protein expression and alternations in mRNA expression, we find that loss of …

Comparative Effects Of Intranasal Neuropeptide Y And Hs014 In Preventing Anxiety And Depressive-Like Behavior Elicited By Single Prolonged Stress, Esther L. Sabban, Lidia I. Serova, Lishay G. Alaluf, Marcela Laukova, Chandana Peddu

NYMC Faculty Publications

Stress triggered neuropsychiatric disorders are a serious societal problem. Prophylactic treatment or early intervention has great potential in increasing resilience to traumatic stress and reducing its harmful impact. Previously, we demonstrated proof of concept that intranasal administration of neuropeptide Y (NPY) or the melanocortin receptor four (MC4R) antagonist, HS014, prior to single prolonged stress (SPS) rodent post-traumatic stress disorder (PTSD) model, can prevent or attenuate many PTSD associated impairments. Here, we compare effects of NPY or HS014 given 30 min before or immediately after SPS stressors on development of anxiety, depressive-like behavior and associated biochemical abnormalities. SPS triggered anxiety on …

Teachers' Attitudes And Their Effect On Placement Recommendations For Students With Cognitive Disabilities, Kathleen M. Everett

Doctor of Education in Special Education Dissertations

The implementation of Public Law 94-142 in 1974 guaranteed that students with disabilities had the right to be educated alongside their peers in the least restrictive environment. However, decades later, administrators, teachers, and parents continue to struggle to resolve the issue on how to include students with disabilities in general education classrooms, as well as how to recognize why students with cognitive disabilities were embodied more in self-contained classrooms than in comprehensive environments. In this study, I aimed to understand how special education teachers’ attitudes about inclusion, LRE, and students with cognitive disabilities influence placement recommendations. Through the qualitative thematic …

Research Publications (2011 to 2015)

Physical activity and aging research has burgeoned in the past few decades. Despite the increase in scholarly publications no attempts have been made to summarize the publication landscape and to identify works that had great impact to physical activity and aging research. We conducted a bibliometric analysis and collected publication data from 1980 to February 6, 2015 in the Web of Science Core Collection. Of the overall 9,935 publications most were published after 2007 and almost 60% were in the category of Geriatrics and Gerontology or Sport Sciences. Highly cited publications (n = 45) were mostly authored by researchers from …

Reducing The Risk Of Suicide On An Inpatient Acute Behavioral Health Unit, Thomas I. Coleman Mr

Master's Projects and Capstones

Evidence suggest for those who have successfully committed suicide in the form of asphyxiation inside locked facilities are more than likely due to patient bathroom doors. The current unit consists of 30 inpatient medical-psychiatric beds serving the adult and geriatric populations. The goal is to ensure patient safety by removing patient bathroom doors and replacing them with breakaway shower curtains for those exhibiting direct signs and symptoms of suicidal ideations with a plan. The specific aim is to improve patient outcomes by decreasing the number of deaths or attempted suicides. With great results, this type of project has been implemented …

Theoretical Analysis And Sph Simulation For The Wave Energy Captured By A Bottom-Hinged Owsc, Yu-Chi Chang, Da-Wei Chen, Yi-Chih Chow, Shiaw-Yih Tzang, Chen-Chou Lin, Jiahn-Horng Chen

Journal of Marine Science and Technology–Taiwan

This paper examines one type of wave energy converter, the Oscillating Wave Surge Converter (OWSC) with its bottom hinged on the sea bed. The simplest form of OWSC is a flapper connected with a power take-off (PTO). Theoretical analysis based on a 2D linear potential theory elucidates the mechanisms of the wave energy capture by a bottom-hinged OWSC in terms of impedances associated with the wave field, the flapper body, and the PTO. Criteria of impedance canceling and matching to maximize the energy capture factor can be deduced. Smoothed Particle Hydrodynamics (SPH) is established for simulating the same problem, and …

Improved Boundary Values Of Ocean Wave Fields Using A Data Assimilation Scheme, Yang-Ming Fan, Heinz Günther, Dong-Jiing Doong, Chia Chuen Kao

Journal of Marine Science and Technology–Taiwan

The objective of this study was to assess the accuracy of numerical wave forecasts through data assimilation of boundary values. A sequential data assimilation scheme was adopted to utilise altimeter data. The performance of the system in terms of operational applications, specifically for typhoon waves, was investigated. Two typhoons that occurred in 2006 around Taiwan (Kaemi and Shanshan) were used as case studies. The proposed data assimilation increased the forecast accuracy of the boundary values in terms of the wave parameters, such as the wave heights and periods. The results showed that after the assimilation, the assimilation model was significantly …
