Water Surface Impact And Ricochet Of Deformable Elastomeric Spheres, Randy Craig Hurd Dec 2017

Water Surface Impact And Ricochet Of Deformable Elastomeric Spheres, Randy Craig Hurd

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soft and deformable silicone rubber spheres ricochet from a water surface when rigid spheres and disks (or skipping stones) cannot. This dissertation investigates why these objects are able to skip so successfully. High speed cameras allow us to see that these unique spheres deform significantly as they impact the water surface, flattening into pancake-like shapes with greater area. Though the water entry behavior of deformable spheres deviates from that of rigid spheres, our research shows that if this deformation is accounted for, their behavior can be predicted from previously established methods. Soft spheres skip more easily because they deform significantly …

Long-Range Interactions For Hydrogen: 6p-1s And 6p-2s Systems, Ulrich D. Jentschura, Chandra M. Adhikari Dec 2017

Long-Range Interactions For Hydrogen: 6p-1s And 6p-2s Systems, Ulrich D. Jentschura, Chandra M. Adhikari

Physics Faculty Research & Creative Works

The collisional shift of a transition constitutes an important systematic effect in highprecision spectroscopy. Accurate values for van der Waals interaction coefficients are required in order to evaluate the distance-dependent frequency shift. We here consider the interaction of excited hydrogen 6P atoms with metastable atoms (in the 2S state), in order to explore the influence of quasi-degenerate 2P and 6S states on the dipole-dipole interaction. The motivation for the calculation is given by planned high-precision measurements of the transition. Due to the presence of quasi-degenerate levels, one can use the non-retarded approximation for the interaction terms over wide distance ranges.

Effect Of Explosive Charge Geometry On Shockwave Propagation, Catherine E. Johnson, Phillip R. Mulligan, Kelly Williams, Martin Langenderfer, Jeffrey Heniff

Mining Engineering Faculty Research & Creative Works

With advancements in the 3D printing of explosives, the understanding how the shape of an explosive charge influences the energy expansion and subsequently the focusing of energy is becoming increasingly more important. Theoretically, explosive charges could be printed to focus the energy on targets of interest or to synthesize nanomaterials. The first step to quantifying the energy expansion and shock wave convergences for a 3D printed charge is to examine simple geometries of traditional explosive charges (non-3D printed). Detonation of 15 PETN-based primasheet charges in the spherical, cubic, cylindrical, and tetrahedral configurations have been examined in this study. Qualitative data …

Differences In Heterospecific Pollen Deposition Across Pollination Syndromes In The Monteverde Area, December 2017, Kara Powell Dec 2017

Differences In Heterospecific Pollen Deposition Across Pollination Syndromes In The Monteverde Area, December 2017, Kara Powell

Monteverde Institute: Tropical Ecology and Conservation

Pollination is an important ecosystem service, increasing the ability of plants to adapt to changing environments through the process of sexual reproduction. The efficiency of pollination can be reduced due to the transfer of heterospecific pollen, which is pollen from another species. Flower characteristics vary in order to attract certain types of pollinators. This phenomenon is classified in groups of flower morphology characteristics known as pollination syndromes. Little research exists that summarizes heterospecific pollen transfer within these pollination syndromes. I investigated pollen deposition across pollination syndromes in Monteverde, Costa Rica in two different sites: San Gerardo and Curi Cancha. I …

We investigate the optical signature of the interface in a single MgZnO/ZnO heterojunction, which exhibits two orders of magnitude lower resistivity and 10 times higher electron mobility compared with the MgZnO/Al2O3 film grown under the same conditions. These impressive transport properties are attributed to increased mobility of electrons at the MgZnO/ZnO heterojunction interface. Depth-resolved cathodoluminescence and photoluminescence studies reveal a 3.2 eV H-band optical emission from the heterointerface, which exhibits excitonic properties and a localization energy of 19.6 meV. The emission is attributed to band-bending due to the polarization discontinuity at the interface, which leads to formation of a triangular …

Littérature Et Pratiques Rituelles : Le Statut Sémiotique Des Signes Mystiques, Yves Dakouo Dec 2017

Littérature Et Pratiques Rituelles : Le Statut Sémiotique Des Signes Mystiques, Yves Dakouo

Présence Francophone: Revue internationale de langue et de littérature

This paper is part of our research project on the analysis of social practices as they appear in the framework of literary works, notably in narrative prose. This does not consist in undertaking a thematic approach of these, but rather considering them as the fourth level of immanence and relevance of the plan of semiotic expression. Therefore, the study is part of the rhetoric of downward integration that occurs when a higher level of immanence occurs at a lower level, like here where practices (4th level) occur in fiction text (2nd level). In this respect, is considered as “ritual practice” …

First Year Teachers' Perceptions Of Their Preparation For Teaching English Language Learners, Veronica Aguiñaga Dec 2017

First Year Teachers' Perceptions Of Their Preparation For Teaching English Language Learners, Veronica Aguiñaga

CUP Ed.D. Dissertations

The number of English language learners (ELLs) in public schools is increasing rapidly throughout the United States. All teachers are expected to meet the individual needs of these culturally and linguistically diverse students in their classrooms. However, little training and guidance in preservice teacher education programs is being provided to prepare future teachers. This study investigated how first year teachers viewed their preparation of working with English language learners in their preservice teacher education program. From a transformative learning lens, it is recommended that preservice teacher education programs consider effective ways to provide a variety of field experiences and classroom …

Internal Medicine Faculty Publications

Following myocardial infarction (MI), overactive inflammation remodels the left ventricle (LV) leading to heart failure coinciding with reduced levels of 15-epi-Lipoxin A4 (15-epi LXA4). However, the role of 15-epi LXA4 in post-MI acute inflammatory response and resolving phase is unclear. We hypothesize that liposomal fusion of 15-epi-LXA4 (Lipo-15-epi-LXA4) or free 15-epi-LXA4 will expedite the resolving phase in post-MI inflammation. 8 to 12-week-old male C57BL/6 mice were subjected to permanent coronary artery ligation. Lipo-15-epi-LXA4 or 15-epi-LXA4 (1 μg/kg/day) was injected 3 hours post-MI for (d)1 or continued daily till d5. 15-epi-LXA4 activated formyl peptide receptor (FPR2) and GPR120 on alternative macrophages …

First Narrow-Band Search For Continuous Gravitational Waves From Known Pulsars In Advanced Detector Data, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website. Dec 2017

First Narrow-Band Search For Continuous Gravitational Waves From Known Pulsars In Advanced Detector Data, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signal-to-noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars …

Caught In The Act - Migration Of A Large Right Atrial Thrombus To Pulmonary Artery During Transthoracic Echocardiography - A Case Report, Bilal Hussain, Fateh Ali Tipoo Sultan, Talha Shahzad, Sumaira Punjani Dec 2017

Caught In The Act - Migration Of A Large Right Atrial Thrombus To Pulmonary Artery During Transthoracic Echocardiography - A Case Report, Bilal Hussain, Fateh Ali Tipoo Sultan, Talha Shahzad, Sumaira Punjani

Section of Cardiology

In cases of pulmonary embolism, the visualization of a free-floating right heart thrombus on conventional transthoracic echocardiography is extremely rare. Even rarer is an echocardiographic recording of migration of a free-floating clot from the right heart into the pulmonary vasculature leading to pulmonary embolism. We present a unique case of an elderly man who presented with dyspnoea, in whom a routine 2-D bed side transthoracic echo recorded the live transit of a free floating thrombus from the right heart into the pulmonary artery resulting in pulmonary embolism. The patient remained haemodynamically stable and was managed with anticoagulation. Our case objectively …
