Learning To Teach And Teaching To Learn, Maria Babiuc-Hamilton

Maria C. Babiuc-Hamilton

New studies show that students do better in science classes that are taught interactively. We compare two different pedagogical approaches in teaching introductory physics: the lecture-based method, the active learning laboratories. We present the data on student performance on exams, homework, lab activities and tests, from 126 students taking the 200-level introductory physics courses at Marshall University, in Huntington, WV. We discuss the efficiency of each method in fostering the success of students in the introductory physics courses. We find that subtle differentiations can be implicitly detected in students’ exam grades, homework, participation, and choice of major.

Movement I From Lamentationes, Timothy W. Mcdunn

CrissCross

This piece is a setting of the first poem in the book of ʼêḵāh from the Hebrew Bible (the book of Lamentations in the Christian Old Testament). Setting the text in its original language has had two primary advantages: (1) it preserved euphony and other poetic subtleties and (2) it left the poetry's original cultural context intact.

I use harmonic rhetoric to imitate several features of the text. One of them is the so-called "tragic reversal," a device illustrated by the lines cited above, where a reversal of fortune is expressed through the contrast between the first colon and the …

We examined organic-walled dinoflagellate cysts from one 210Pb-dated sediment core and 39 surface sediment samples from the northern Gulf of Mexico to determine the relationship between nutrient enrichment and cyst assemblages in this region characterized by oxygen deficiency. The core spans from 1962 to 1997 and its sampling location is directly influenced by the Mississippi River plume. Surface sediments were collected in 2006, 2007, 2008, and 2014 and represent approximately 1 to 4 years of accumulation. A total of 57 cyst taxa were recorded, and four heterotrophic taxa in particular were found to increase in the top section (1986–1997) of …

Ion Parallel Closures, Jeong-Young Ji, Hankyu Q. Lee, Eric D. Held

All Physics Faculty Publications

Ion parallel closures are obtained for arbitrary atomic weights and charge numbers. For arbitrary collisionality, the heat flow and viscosity are expressed as kernel-weighted integrals of the temperature and flow-velocity gradients. Simple, fitted kernel functions are obtained from the 1600 parallel moment solution and the asymptotic behavior in the collisionless limit. The fitted kernel parameters are tabulated for various temperature ratios of ions to electrons. The closures can be used conveniently without solving the kinetic equation or higher order moment equations in closing ion fluid equations.

Investigation Of Aerosol Optical And Chemical Properties Using Humidity Controlled Cavity Ring-Down Spectroscopy, Xijing Zhu

Dissertations and Theses

Scientists have been observing a change in the climate since the beginning of the 20^th century that cannot be attributed to any of the natural influences of the past. Natural and anthropogenic substances and processes perturb the Earth's energy budget, contributing to climate change. In particular, aerosols (particles suspended in air) have long been recognized to be important in processes throughout the atmosphere that affect climate. They directly influence the radiative balance of the Earth's atmosphere, affect cloud formation and properties, and are also key air pollutants that contribute to a variety of respiratory and cardiovascular diseases. Despite their …

Publications and Research

Background: Pretargeting-based approaches are being investigated for radioimmunoimaging and therapy applications to reduce the effective radiation burden to the patient. To date, only a few studies have used short-lived radioisotopes for pretargeting of antibodies, and such examples with internalizing antibodies are even rarer. Herein, we have investigated pretargeting methodology using inverse electron-demand Diels-Alder (IEDDA) for tracing two clinically relevant, internalizing monoclonal antibodies, cetuximab and trastuzumab.

Results: Bioorthogonal reaction between tetrazine and trans-cyclooctene (TCO) was used for tracing cetuximab and trastuzumab in vivo with a fluorine-18 (t½ = 109.8 min) labelled tracer. TCO-cetuximab or TCO-trastuzumab was administered 24, 48, or 72 …

Investigating The Mechanism Of Deep-Focus Earthquakes Via In-Situ Acoustic Emission Experiments On Fe2sio4 At High Temperature And Pressure, Timothy Officer

Electronic Thesis and Dissertation Repository

In subduction zones, earthquakes are thought to be associated with faulting that arises from phase transformations. In order to test the viability of this mechanism experimentally, it was necessary to make microseismic measurements while the mineral under investigation was subjected to the pressure and temperature (P,T) conditions corresponding to their environment at depth. A system has been developed capable of making in situ acoustic emission (AE) measurements on samples under P,T conditions representative of the upper mantle and transition zone. Experiments were performed in a 3000-ton multi-anvil press using an 18/11 octahedral cell with 6 piezoelectric transducers mounted on the …

Self-Assembly Of Tiles: Theoretical Models, The Power Of Signals, And Local Computing, Amirhossein Simjour

Electronic Thesis and Dissertation Repository

DNA-based self-assembly is an autonomous process whereby a disordered system of DNA sequences forms an organized structure or pattern as a consequence of Watson-Crick complementarity of DNA sequences, without external direction.

Here, we propose self-assembly (SA) hypergraph automata as an automata-theoretic model for patterned self-assembly. We investigate the computational power of SA-hypergraph automata and show that for every recognizable picture language, there exists an SA-hypergraph automaton that accepts this language. Conversely, we prove that for any restricted SA-hypergraph automaton, there exists a Wang Tile System, a model for recognizable picture languages, that accepts the same language.

Moreover, we investigate the …

Shape Modeling And Boulder Mapping Of Asteroid 1992 Uy4, Nicholas Duong

Posters-at-the-Capitol

The structure and history of near-Earth asteroids are important to
study because they collide with Earth, sometimes with significant consequences for
climate and the survival of many species, including our own. If NASA is ever to deflect an asteroid on a collision course, it is crucial to know as much as possible about its size, composition, structure and boulder distribution. The boulder
distribution in turn helps to map the asteroid's gravitational field.

1992 UY4 is a near-Earth asteroid discovered in 1992. In August 2005, UY4 made a
``close" (for space) pass of Earth, about 15x farther than the Moon. It …

An Observational And Modeling Study Of Mesoscale Airmasses With High Theta-E, Lawrence Wolfgang Hanft

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Typically, the cool side of an airmass boundary is stable to vertical motions due to its associated negative buoyancy. However, under certain conditions, the air on the cool side of the boundary can undergo a transition wherein it assumes an equivalent potential temperature and surface-based convective available potential energy that is higher than that of the airmass on the warm side of the boundary. The resultant airmass is herein referred to as a mesoscale airmass with high theta-e (MAHTE).

Results are presented from an observational and mesoscale modeling study designed to examine MAHTE characteristics and the processes responsible for MATHE …

Sulfur Isotope Variations In The Elk Creek Carbonatite Complex, Southeastern Nebraska, Usa, Emily Campbell

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The Elk Creek Carbonatite Complex (ECCC) comprises eight different units of carbonatite and silicate rocks, including a magnetite-dolomite carbonatite that hosts the largest niobium deposit in the United States. This study focused on interpreting the first set of sulfur isotopes from this system to decipher between magmatic and secondary processes. Using sulfur isotope variations I was able to discriminate between hypogene and supergene mineralization, and measure (1) formation temperatures (2) possible sulfur source (3) degassing effects on isotopic composition, and (4) post-magmatic alteration. The groundwork for mapping and interpreting iron oxide alteration is also laid out in this thesis.
