Anthropometric Multicompartmental Model To Predict Body Composition In Brazilian Girls, Dalmo Machado, Analiza Silva, Luis Gobbo, Paula Elias, Francisco J.A. De Paula, Nilo Ramos

Teacher Education

Background: Anthropometric models remain appropriate alternatives to estimate body composition of peripubertal populations. However, these traditional models do not consider other body components that undergo major changes during peripubertal growth spurt, with restrictions to a multicompartimental approach as a quantitative growth. DXA has great potential to determine pediatric body composition in more than one component (3-C), but has limited use in field settings. Thus, the aim of this study was to propose and validate an anthropometric model for simultaneous estimation of lean soft tissue (LST), bone mineral content (BMC) and fat mass (FM) in healthy girls, from a multivariate approach …

Encoding Lexicographical Ordering Constraints In Sat, Wenting Zhao

Honors Projects

Symmetry occurs in many constraint satisfaction problems, and it is important to deal with it efficiently and effectively, as it often leads to an exponential number of isomorphic assignments. Symmetric rows and columns in matrices are an important class of symmetries in constraint programming. In this work, we develop a new SAT encoding for partial lexicographical ordering constraints to break symmetries in such places. We also survey all the previous complete lex-leader encodings in literature and translate them into SAT encodings. We perform experimental analysis on how these lex-leader constraints impact the solving of Balanced Incomplete Block Design (BIBD) instances. …

Atomistic Simulations And Network-Based Modeling Of The Hsp90-Cdc37 Chaperone Binding With Cdk4 Client Protein: A Mechanism Of Chaperoning Kinase Clients By Exploiting Weak Spots Of Intrinsically Dynamic Kinase Domains, John Czemeres, Kurt Buse, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

A fundamental role of the Hsp90 and Cdc37 chaperones in mediating conformational development and activation of diverse protein kinase clients is essential in signal transduction. There has been increasing evidence that the Hsp90-Cdc37 system executes its chaperoning duties by recognizing conformational instability of kinase clients and modulating their folding landscapes. The recent cryo-electron microscopy structure of the Hsp90-Cdc37- Cdk4 kinase complex has provided a framework for dissecting regulatory principles underlying differentiation and recruitment of protein kinase clients to the chaperone machinery. In this work, we have combined atomistic simulations with protein stability and network-based rigidity decomposition analyses to characterize dynamic …

Gamma-Ray Metallic Magnetic Calorimeters With Nbta Passive Persistent Switches And Electroformed Au Absorbers, Ruslan Hummatov

Physics & Astronomy ETDs

Metallic Magnetic Calorimeters (MMCs) are low temperature particle detectors which can be used for a wide range of applications including high-resolution γ -ray spectroscopy. High energy resolution in γ -ray spectroscopy is desired for Non Destructive Assay (NDA) of nuclear material and improved measurements of nuclear data. Our group has been developing γ -ray MMCs that should ultimately provide energy resolution more than an order of magnitude better than the benchmark detector technology, high purity germanium detectors (HPGe). Two components of these MMCs have been developed as a part of this dissertation: an on-chip passive superconducting persistent current switch and …

Microstructure And Mechanical Properties Of Additive Manufacturing Titanium Alloys After Thermal Processing, Ahmet Alptug Tanrikulu

Dissertations and Theses

Titanium alloys are widely used for aerospace and biomaterial applications since their high specific strength, and high corrosion resistivity. Besides these properties, titanium is an excellent biocompatible material widely used for internal body implants. Because the products have complex geometries in both applications, Additive Manufacturing (AM) methods have been recently applied for production. AM methods can process a direct 3-D shape of the final product, decrease total production time and cost. However, high residual stress of the final product limits the application of AM components, especially the ones that are exposed to cyclic loading. In the present study, the initial …

Grounded Practical Theory To Improve Persistence-Retention Strategic Enrollment Management, Kenneth W. Borland Jr.

Journal of Research, Assessment, and Practice in Higher Education

The author introduces grounded practical theory (GPT) as a useful research approach in the field of strategic enrollment management (SEM) and its focus on persistence-retention. The GPT approach is then illustrated by engaging sample voices of persistence-retention and SEM; scientific theory (the philosophical level) and normative theory (the technical level) as observed in the literature. The scientific theory voices and normative theory voices are then positioned in relation to voices of students and practitioners (observed respondents) who have identified real world persistence-retention and SEM problems. These problems suggest implications for reconstructing the relationship between persistence-retention and SEM philosophical, theoretical, and …

Nearshore Salinity And Juvenile Pink Shrimp (Farfantepenaeus Duorarum): Integrating Field Observations, Laboratory Trials, And Habitat Suitability Simulations, Ian C. Zink

Open Access Dissertations

The pink shrimp Farfantepenaeus duorarum is one ecological indicator of the Biscayne Bay Coastal Wetlands (BBCW) project, which intends to increase mesohaline and oligohaline areal extent along southwestern Biscayne Bay nearshore areas. These changes were anticipated to benefit pink shrimp abundances. My dissertation tested whether increased mesohaline and oligohaline area within a 50-m strip of shallow-water shoreline area likely would increase pink shrimp densities. First, I carried out a comprehensive literature review that revealed polyhaline and/or euhaline salinity regimes generally maximized pink shrimp occurrence, abundance, growth, and survival. Next, I analyzed 10 yrs of pink shrimp density and habitat observations …

Does Being An Expert Make You More Negative? An Investigation Of Subjective Expertise And Electronic Word-Of-Mouth Communication, Jiangmeng Liu

Open Access Dissertations

This dissertation is aimed at filling a gap in electronic word-of-mouth (eWOM) literature by examining how communicator’s subjective expertise impacts generation of eWOM. Based on a review of literature in psychology, marketing, consumer research, and communication, four underlying mechanisms (sense of power, dogmatic cognition style, hubristic pride, and emotions) were proposed to explain the effect of subjective expertise. Two distinctive features of eWOM platforms were incorporated into the study as potential moderators: anonymity and audience size of the review platform. Based on prior literature, this study proposed 14 hypotheses in total and 2 research questions. Two empirical studies were conducted. …

Mitoneet (Cisd1) Knockout Mice Show Signs Of Striatal Mitochondrial Dysfunction And A Parkinson's Disease Phenotype, Werner J. Geldenhuys, Stanley A. Benkovic, Li Lin, Heather M. Yonutas, Samuel D. Crish, Patrick G. Sullivan, Altaf S. Darvesh, Candice M. Brown, Jason R. Richardson

Clinical and Translational Science Institute

Mitochondrial dysfunction is thought to play a significant role in neurodegeneration observed in Parkinson’s disease (PD), yet the mechanisms underlying this pathology remain unclear. Here, we demonstrate that loss of mitoNEET (CISD1), an iron–sulfur containing protein that regulates mitochondrial bioenergetics, results in mitochondrial dysfunction and loss of striatal dopamine and tyrosine hydroxylase. Mitochondria isolated from mice lacking mitoNEET were dysfunctional as revealed by elevated reactive oxygen species (ROS) and reduced capacity to produce ATP. Gait analysis revealed a shortened stride length and decreased rotarod performance in knockout mice, consistent with the loss of striatal dopamine. Together, these data suggest that …

Trade In Environmental Goods: Empirical Exploration Of Direct And Indirect Effects On Pollution By Country’S Trade Status, Natalia Zugravu-Soilita

Fondazione Eni Enrico Mattei Working Papers

Based on panel data covering 114 countries in the world, this study investigates the direct, indirect and total effects of trade flows in environmental goods (EG) on total CO2 and SO2 emissions. Our system-GMM estimations reveal positive direct scale – [between-industry] composition effects prevailing on the negative direct technique – [within-industry] composition effects (if any), as well as compensating the significant indirect technique effects channelled by the stringency of environmental regulations and per capita income. If the net importers of EGs (namely from the APEC54 and WTO26 lists) are recurrently found to face increased pollution (in particular CO2 emissions) due …

Subaru And Salt Spectroscopy Of Chemically Peculiar Hot Subdwarfs, C. Simon Jeffery, Naslim Neelamkodan, Vincent M. Woolf, Steven M. Crawford, Roy H. Østensen

College of Natural and Applied Sciences

The majority of hot subdwarfs lie on or close to the helium main-sequence. Many have hydrogen-rich surfaces, but a substantial fraction of the hotter subdwarfs have hydrogen-depleted or hydrogen-deficient surfaces. Amongst the former, three were known to show extraordinary overabundances of heavy elements including zirconium and lead. Using Subaru/HDS,we commenced a high-resolution survey of hydrogen-depleted subdwarfs to discover new members of the class. UVO 0825+15, was found to exhibit strong lead lines, to be an intrinsic variable in K2 field 5, and to have a relatively high space motion. Two other lead-rich subdwarfs have been found in the Subaru sample. …

We present spatially and spectrally resolved Atacama Large Millimeter/submillimeter Array (ALMA) observations of gas and dust orbiting the pre-main-sequence hierarchical triple-star system GW Ori. A forward modeling of the ¹³CO and C¹⁸O J = 2–1 transitions permits a measurement of the total stellar mass in this system, 5.29 ± 0.09 M_⊙, and the circumtriple disk inclination, 137 fdg 6 ± 2 fdg 0. Optical spectra spanning a 35 yr period were used to derive new radial velocities and, coupled with a spectroscopic disentangling technique, revealed that the A and B components of GW Ori form a …

Pulsar J1411+2551: A Low-Mass Double Neutron Star System, J. G. Martinez, K. Stovall, P. C.C. Freire, J. S. Deneva, T. M. Tauris, A. Ridolfi, N. Wex, Fredrick Jenet, M. A. Mclaughlin, M. Bagchi

Physics & Astronomy Faculty Publications

In this work, we report the discovery and characterization of PSR J1411+2551, a new binary pulsar discovered in the Arecibo 327 MHz Drift Pulsar Survey. Our timing observations of the radio pulsar in the system span a period of about 2.5 years. This timing campaign allowed a precise measurement of its spin period (62.4 ms) and its derivative (9.6 ±0.7) ×10 -20 s s -1 ; from these, we derive a characteristic age of >9.1 Gyr and a surface magnetic field strength of < 2.6 ×10 9 G. These numbers indicate that this pulsar was mildly recycled by accretion of matter from the progenitor of the companion star. The system has an eccentric (e =0.17) 2.61 day orbit. This eccentricity allows a highly significant measurement of the rate of advance of periastron, . Assuming general relativity accurately describes the orbital motion, this implies a total system mass M =2.538 ±0.022 M o . The minimum companion mass is 0.92 M o and the maximum pulsar mass is 1.62 M o . The large companion mass and the orbital eccentricity suggest that PSR J1411+2551 is a double neutron star system; the lightest known to date including the DNS merger GW170817. Furthermore, the relatively low orbital eccentricity and small proper motion limits suggest that the second supernova had a relatively small associated kick; this and the low system mass suggest that it was an ultra-stripped supernova.

Fossil Fuel Subsidies In America, Jackson Cutsor

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Two of the most controversial topics in American politics today are climate change and the federal budget. Subsidies for energy generation fit into both categories.

Subsidies given to the energy industry artificially decrease the price of energy and electricity. Low energy prices help stimulate the market, however, the negative externalities like the social cost of carbon and political corruption are not taken into consideration.

Subsidies can come in many forms including: failure to impose external costs, tax breaks, and low interest loans. Even without imposing the social cost of carbon a removal of fossil fuel energy subsidies can have a …
