Delivering Core Engineering Concepts To Secondary Level Students, Chris Merrill, Rodney L. Custer, Jenny Daugherty, Martin Westrick, Yong Zeng

Publications

Within primary and secondary school technology education, engineering has been proposed as an avenue to bring about technological literacy (Lewis, 2005; Dearing & Daugherty, 2004). Different initiatives such as curriculum development projects (i.e., Project ProBase and Project Lead The Way) and National Science Foundation funded projects such as the National Center for Engineering and Technology Education (NCETE) have been developed to infuse engineering into primary and secondary education. For example, one key goal of the technology teacher education component of NCETE is to impact the focus and content of the technology education field at the secondary level (National Center for …

A Survey Of Apomixis And Ploidy Levels Among Poa L. (Poaceae) Using Flow Cytometry, Alicia Michelle Kelley, Paul G. Johnson, Blair L. Waldron, Michael D. Peel

CWEL Publications

Poa is a complex genus taxonomically and genetically. As a result, relatively little information exists for this economically important genus with regards to reproductive mode and variability in chromosome number. We examined apomixis frequency and ploidy levels in 83 Poa accessions representing 33 species from the National Plant Germplasm System using flow cytometric techniques. In reproductive mode analysis, we analyzed at least three preparations of 50 seeds each from the accessions. In ploidy level analysis, at least three plants of each accession were analyzed. Sixty percent of the species had at least one apomictic or facultative apomictic accession; 40% were …

Liposomes Recruit Ipac To The Shigella Flexneri Type Iii Secretion Apparatus Needle As A Final Step In Secretion Induction, C. R. Epler, Nicholas E. Dickenson, A. J. Olive, W. L. Picking, W. D. Picking

Chemistry and Biochemistry Faculty Publications

Shigella flexneri contact with enterocytes induces a burst of protein secretion via its type III secretion apparatus (TTSA) as an initial step in cellular invasion. We have previously reported that IpaD is positioned at the TTSA needle tip (M. Espina et al., Infect. Immuno. 74:4391-4400, 2006). From this position, IpaD senses small molecules in the environment to control the presentation of IpaB to the needle tip. This step occurs without type III secretion induction or IpaC recruitment to the S. flexneri surface. IpaC is then transported to the S. flexneri surface when target cell lipids are added, and this event …

Molecular Mechanisms Of Estrogen-Dependent Transcriptional Regulation Through Ap-1, Gary D. Isaacs

Faculty Dissertations

Gene regulation by estrogen (E2) plays an important role in mediating physiological responses in normal and disease states. Estrogen receptors (ERs) facilitate these responses by at least two genomic modes of action: (1) binding directly to estrogen response elements (EREs) or (2) binding indirectly to DNA through transcription factors (like AP-1). Although the ERE pathway is well studied, little is known about the mechanism of E2-dependent actions through this indirect pathway (e.g., ER/AP-1 pathway).

Using an unbiased proteomic approach, I examine the composition of AP-1 complexes in order to better understand the foundation of ER tethering. The results from this …

Molecular And Morphological Divergence In A Pair Of Bird Species And Their Ectoparasites, Noah K. Whiteman, Vishal S. Dosanjh, Ricardo L. Palma, Joshua M. Hull, Rebecca T. Kimball, Pablo Sánchez, José Hernán Sarasola, Patricia G. Parker

Biology Department Faculty Works

In an evolutionary context, parasites tend to be morphologically conservative relative to their hosts. However, the rate of neutral molecular evolution across many parasite lineages is faster than in their hosts. Although this relationship is apparent at the macroevolutionary scale, insight into the processes underpinning it may be gained through investigations at the microevolutionary scale. Birds and their ectoparasitic lice have served as important natural experiments in co-evolution. Here, we compared mitochondrial and morphological divergence in 2 recently diverged avian host lineages and their parasites. Glapagos hawks (Buteo galapagoensis) are phenotypically divergent from their closest mainland relatives, the Swainson's hawk …

High-Resolution, Long-Term Characterization Of Bacterial Motility Using Optical Tweezers, Lon Chubiz, Taejin Min, Patrick Mears, Christopher Rao, Ido Golding, Yann Chemla

Biology Department Faculty Works

We present a single-cell motility assay, which allows the quantification of bacterial swimming in a well-controlled environment, for durations of up to an hour and with a temporal resolution greater than the flagellar rotation rates of ∼100 Hz. The assay is based on an instrument combining optical tweezers, light and fluorescence microscopy, and a microfluidic chamber. Using this device we characterized the long-term statistics of the run-tumble time series in individual Escherichia coli cells. We also quantified higher-order features of bacterial swimming, such as changes in velocity and reversals of swimming direction.

The Chinese Regulatory Licensing Regime For Pharmaceutical Products: A Law And Economics Analysis, Qing Zhang

Michigan Telecommunications & Technology Law Review

China's pharmaceutical market has expanded dramatically in the past twenty years and is expected to become the largest in the world by the year 2050. However, entry to the market remains difficult for many international pharmaceutical manufacturers due to the country's costly and complicated regulatory licensing requirements. This Article provides an overview of the regulatory licensing regime for pharmaceutical products in China. Then, the Article evaluates three key features of the regulatory licensing regime through a law and economics approach. These features include the use of licensing, as contrasted with alternative regulatory and non-regulatory mechanisms; the standards to be met …

Generic Preemption: Applying Conflict Preemption After Wyeth V. Levine, Hannah B. Murray

Michigan Telecommunications & Technology Law Review

If a generic manufacturer does not have control over its safety warnings, can it comply with the obligations posed by state tort liability? State failure-to-warn actions evaluate whether a product manufacturer has met its obligation to warn consumers about known dangers associated with its product. In essence, if a manufacturer knows about a potentially dangerous outcome, it has a duty to warn its consumers. If the generic manufacturer can comply with a state duty to warn only by changing a label that the FDA will not allow it to change, it becomes impossible for the corporation to meet both requirements. …

Bubble Behavior In Nucleate Boiling Experiment Aboard The Space Shuttle, Justin P. Koeln, Jeffrey C. Boulware, Heng Ban

All Physics Faculty Publications

Boiling dynamics in microgravity need to be better understood before heat transfer systems based on boiling mechanism can be developed for space applications. This paper presents the results of a nucleate boiling experiment aboard Space Shuttle Endeavor (STS- 108). The experiment utilized nickel-chromium resistance wire to boil water in microgravity, and the data was recorded with a CCD camera and six thermistors. This data was analyzed to determine the behavior of bubble formation, detachment from the heating wire, and travel in the water with effects of drag on bubble movement. Bubbles were observed to be ejected from the wire, travel …

Analysis Of The Accase Mutation Profile Of Italian Ryegrass (Lolium Perenne Ssp. Multiflorum) Accessions Resistant To Accase Inhibitors, Thomas Stark

Inquiry: The University of Arkansas Undergraduate Research Journal

Lolium perenne ssp. multiflorum (Italian ryegrass) resistant to ACCase inhibiting herbicides has been reported in many wheat producing counties across Arkansas. Resistance is believed to be the result of point mutations creating amino acid substitutions in the CT domain of the plastidic ACCase gene. This study explores the occurrence of mutations in the ACCase gene of ryegrass populations. Plant material was collected and DNA was extracted from 10 Arkansas ryegrass populations. Six of the populations were known to be resistant to the ACCase inhibitor diclofop-methyl, while the remaining four populations were known to be susceptible to diclofop-methyl. Two highly conserved …

Reviewing The Drivers And Challenges In Rfid Implementation In The Pharmaceutical Supply Chain, Mazen S. Matalka, John K. Visich, Suhong Li

Management Department Faculty Journal Articles

Counterfeiting is a global phenomenon that poses a serious financial threat to the pharmaceutical industry and more importantly jeopardizes public safety and security. Different measures, including new laws and regulations, have been put in place to mitigate the threat and tighten control in the pharmaceuticals supply chain. However, it appears that the most promising countermeasure is track-and-trace technology such as electronic-pedigree (E-pedigree) with Radio Frequency Identification (RFID) technology. In this study we present a framework exploring the antecedents and consequences of RFID applications in the pharmaceutical supply chain. The framework proposes that counterfeiting and E-pedigree regulation will drive the implementation …

A Study Of The Morphology Of Tatenectes Laramiensis, A Cryptocleidoid Plesiosaur From The Sundance Formation (Wyoming, Usa), Hallie P. Street

Theses, Dissertations and Capstones

Tatenectes laramiensis is a cryptocleidoid plesiosaur from the Late Jurassic Sundance Formation. This study primarily concerns a partial skeleton comprised of dorsal vertebrae, ribs, gastralia, and pelvic girdle. Even though the skeleton is incomplete, it is hypothesized that the preserved fossils are sufficient to indicate the overall body shape and also the preferred habitat of Tatenectes. Possibly the most notable of the novel characters is the pachyostotic state of the gastralia. In relation to the ribs and overall size of Tatenectes, in comparison to the gastralia in related taxa, these gastralia are disproportionately robust. The combination of these morphologies suggests …

Status Assessment And Conservation Action Plan For The Long-Billed Curlew (Numenius Americanus), Suzanne D. Fellows, Stephanie L. Jones

United States Fish and Wildlife Service: Publications

The historical breeding range of Long-billed Curlews (Numenius americanus) was the western U.S. and the southern Canadian Prairie Provinces from California north to British Columbia and east to southern Manitoba and Wisconsin, northern Iowa and eastern Kansas. However, this breeding distribution has contracted and Long-billed Curlews have lost about 30% of their historical range. The eastern edge of the current breeding range is the western Great Plains from the Texas panhandle north throughout southwestern and south central Saskatchewan. Long-billed Curlews currently winter along the southwestern U.S. coast from central California, southern Texas and Louisiana south along both of …

Endothelial Cells And Pulmonary Arterial Hypertension: Apoptosis, Proliferation, Interaction And Transdifferentiation, Seiichiro Sakao, Koichiro Tatsumi, Norbert F. Voelkel

VCU Health Publications

Severe pulmonary arterial hypertension, whether idiopathic or secondary, is characterized by structural alterations of microscopically small pulmonary arterioles. The vascular lesions in this group of pulmonary hypertensive diseases show actively proliferating endothelial cells without evidence of apoptosis. In this article, we review pathogenetic concepts of severe pulmonary arterial hypertension and explain the term "complex vascular lesion ", commonly named "plexiform lesion", with endothelial cell dysfunction, i.e., apoptosis, proliferation, interaction with smooth muscle cells and transdifferentiation.

Risk Factors For Human Infection With Puumala Virus, Southwestern Germany, Anne Caroline Schwarz, Ulrich Ranft, Isolde Piechotowski, James E. Childs, Stefan O. Brockmann

Zoonotics and Wildlife Disease: Publications

Puumala virus, which causes nephropathia epidemica (NE), is the most prevalent hantavirus in Germany; bank voles serve as the main reservoir. During 2001–2007, most NE cases reported from Germany occurred in the southwestern state of Baden-Württemberg. We investigated the influence of bank vole habitats (beech forest, seed plants), vole food supply (beechnut mast), climate factors (winter and spring temperatures), and human population density on spatial and temporal occurrence of NE cases in Baden- Württemberg. Using Poisson-regression analyses, we found that all these factors influenced disease incidence. Furthermore, an independent trend of increasing incidence predicted that incidence will nearly double each …
