Measuring The Pore Sizes Of Sol-Gels Using Argon Effusion Techniques, Thomas J. Noel Ii, Krista Mincey, Catrena Higginbotham

The Corinthian

The rate of effusion of argon through a sol-gel scaffold will be measured to determine the size of the pores. The effusion rate will then be used to correlate initial pore size to any pore shrinkage that occurs. We will attempt to control the initial pore size by using various-sized paraffin beads as templates throughout the organically modified tetramethoxysilane (TMOS) gel scaffold. Polyethylene glycol (PEG) will also be used to prop open the pore openings and keep them from closing during the drying process.

Low-Flow Helmholtz Resonator For Molar Mass Detection, Brackman Amy, Amanda Kea, Kenneth Mcgill

The Corinthian

A simple apparatus was constructed for an undergraduate physical chemistry laboratory to determine a mathematical model of wavelike motion. The apparatus was assembled by attaching an airflow valve connected to a tank of argon gas to a GC column, thus creating regulated airflow. The air was manipulated to gently flow over a small sensitive microphone that was attached to an inexpensive resonator. A model will be developed to measure the speed of sound that will lead to the measurement of the molar mass.

In The Person Of Mankind Attempting To Depict Womanhood, Jessica Sedor

The Corinthian

Ben Jonson was by no means a minor character of the early seventeenth century. His writings ranged from plays like Sejanus and Every Man in His Humor to poems like "Song: To Celia" and "To the Memory of My Beloved", "The Author", "Mr. William Shakespeare", and "What He Hath Left Us." He was bold in his attempts. As a result, while many of his works are extremely popular, there are several that proved to be not so successful. Jonson's attempt at speaking as a woman in his "In the Person of Womankind (In Defense of their Inconstancy)" is one example. …

Extrajunctional Resting Ca2+ Influx Is Not Increased In A Severely Dystrophic Expiratory Muscle (Triangularis Sterni) Of The Mdx Mouse, C. George Carlson, Anton Gueorguiev, Diana M. Roshek, Rebecca Ashmore, Jacquelyne S. Chu, Judy E. Anderson

All KCOM Faculty Publications

Freshly isolated adult mdx and nondystrophic (C57B110SnJ) muscle fibers were used to examine the potential role of resting Ca2+ influx in the pathogenesis of Duchenne and related dystrophies. Microfluorimetric determinations of resting divalent cation influx were obtained from undissociated intact muscle fibers in the triangularis sterni (TS), a thin expiratory muscle. Morphological evidence indicated severe dystrophic alterations in the mdx TS at 5 months, and a prononunced loss of fibers with connective tissue infiltration in older animals. To examine resting Ca 2+ influx, fibers were loaded with FURA PE3 and the rate of quenching of intracellular signal following the extracellular …

Beyond The Precautionary Principle, Cass R. Sunstein

Public Law and Legal Theory Working Papers

The precautionary principle has been highly influential in legal systems all over the world. In its strongest and most distinctive forms, the principle imposes a burden of proof on those who create potential risks, and it requires regulation of activities even if it cannot be shown that those activities are likely to produce significant harms. Taken in this strong form, the precautionary principle should be rejected, not because it leads in bad directions, but because it leads in no directions at all. The principle is literally paralyzing— forbidding inaction, stringent regulation, and everything in between. The reason is that in …

Business Divisions From The Perspective Of The U.S. Banking System , Carl Felsenfeld, Genci Bilali

Faculty Scholarship

The Bank Holding Company Act of 1956 ("Act"),' as amended, most recently in 1999 by the Gramm-Leach-Bliley Act ("GLB") divides all economic activity into five groups. These groups are: 1) banking, 2) activities closely related to and a proper incident to banking; 3) activities of a financial nature; 4) activities complimentary to those of a financial nature; and 5) activities not of a financial nature. This article will explore these five groups of activities separately. The policies behind the divisions will be analyzed and questioned whether they serve the policies behind the Act. This article will also question whether the …

The Principal's Role In Promoting Success For Culturally And Linguistically Diverse Students: A Participatory Research Study, Maria Norma Martinez

Doctoral Dissertations

We need to understand more fully what facilitates success in schools with diverse populations. Through participatory research, the voices of school principals who are responsive to the needs of culturally and linguistically diverse students were recorded and analyzed to provide insights on the practices that promote the school success of culturally and linguistically diverse students. Using a dialogic retrospective, the participants had the opportunity to engage, individually and collectively, in reflection and dialogue to identify common themes that emerged in their important work as school leaders and as advocates for diverse students.

Comparative Genetics Of Crop Plant Domestication And Evolution, Anne Frary, Sami̇ Doğanlar

Turkish Journal of Agriculture and Forestry

Domesticated species differ from their wild ancestors and relatives for a set of traits that is known as the domestication syndrome. The most important syndrome traits include growth habit, flowering time, seed dispersal, gigantism and morphological diversity. This paper reviews what is known about the genetic control of domestication traits with an emphasis on comparative analyses that examine this control in two or more crop species. Such analyses indicate that although most domestication traits are quantitatively controlled, the dramatic morphological changes that accompanied domestication may be due to relatively few genes. These studies also show that domestication genes have been …

An Econometric Analysis Of Apricot Supply And Export Demand In Turkey, İlkay Dellal, A. Ali̇ Koç

Turkish Journal of Agriculture and Forestry

This study estimates a supply model for apricots and an export demand model for dried apricots for Turkey to provide unit-free measure coefficients for better supply and marketing management. Using parameter estimates from the models and sample average data, elasticities of long-run supply, price-yield and export of dried apricots were computed as 0.72, 0.54 and -0.87 respectively. From the price dependent export demand model, the price flexibility of dried apricots was calculated as -0.71. In this study, the import demand elasticities of dried apricots for major destination countries were estimated and found to be inelastic. An evaluation of aggregated household …

The purpose of this study was to examine the statistical significance between the instructional strategies of the REW ARDS program and a control group by teaching word chunking, or multisyllablism, to increase struggling middle school readers' decoding, reading fluency, and spelling accuracy. An experimental design of pretest, intervention (REW ARDS), and posttest with non-random groups, including a control group, was utilized. The study included three teachers and 23 sixth and seventh graders from two middle schools to test the null hypothesis. The null hypothesis was accepted, not rejected, which used five separate t-tests to statistically prove significance in the areas …

The Analysis Of Partial Dominance Of Intragenic Mutations At The Adh Locus In Drosophila Melanogaster At Two Different Alcohol Concentrations, Vatan Taşkin

Turkish Journal of Biology

The dominance of a de novo mutation determines its effect on the viability of the first and succeeding generations; therefore, it is a major factor in estimating the risk from mutations to human health. It is well established that large deletions lead to significant dominance, but until the recent development of molecular methods for amplification and sequencing of mutations it was not possible to determine the dominance of specific intragenic changes in DNA. The purpose of this study was to determine the dominance for a series of Adh-null mutations, each with a minimum mutation of a transition at one base …

Study On Papain Immobilization On A Macroporous Polymer Carrier, Liang Ding, Zihua Yao, Tong Li, Qiang Yue, Jia Chai

Turkish Journal of Chemistry

Macroporous resin microbeads of methyl methacrylate-divinyl benzene copolymer were synthesized by radical suspension polymerization of acrolein with divinylbenzene in the presence of a pore-creating agent, petroleum ether. The microbeads had a large specific surface area and large pores covered the entire surface of the resin. This macroporous polymer carrier was aminated by hydrazine hydrate that produced a large number of amino groups on the carrier. Papain was immobilized on the porous polymer carrier by glutaraldehyde cross-linking or diazo-coupling. The factors involved in the activity recovery of the immobilized papain and the enzymic properties of the resulting immobilized papain were studied …

Maximin Share And Minimax Envy In Fair-Division Problems, Marco Dall'aglio, Theodore P. Hill

Research Scholars in Residence

For fair-division or cake-cutting problems with value functions which are normalized positive measures (i.e., the values are probability measures) maximin-share and minimax-envy inequalities are derived for both continuous and discrete measures. The tools used include classical and recent basic convexity results, as well as ad hoc constructions. Examples are given to show that the envy-minimizing criterion is not Pareto optimal, even if the values are mutually absolutely continuous. In the discrete measure case, sufficient conditions are obtained to guarantee the existence of envy-free partitions.

A Portable Eddy Covariance System For The Measurement Of Ecosystem–Atmosphere Exchange Of Co2, Water Vapor, And Energy, Dave P. Billesbach, M.L. Fischer, Margaret S. Torn, J.A. Berry

Department of Agricultural and Biological Systems Engineering: Faculty Publications

To facilitate the study of flux heterogeneity within a region, the authors have designed and field-tested a portable eddy covariance system to measure exchange of CO2, water vapor, and energy between the land surface and the atmosphere. The combination of instrumentation used in this system allows high precision flux measurements without requiring on-site infrastructure such as prepositioned towers or line power. In addition, the system contains sensors to measure a suit of soil, climatic, and energy-related parameters that are needed to quality control the fluxes and to characterize the flux footprint. The physical design and instrument packaging used in the …

Phase Retrieval Using A Genetic Algorithm On The Systematic Image-Based Optical Alignment Test Bed, Jaime R. Taylor

Physics Faculty Research

NASA’s Marshall Space Flight Center’s Systematic Image-Based Optical Alignment (SIBOA) Testbed was developed to test phase retrieval algorithms and hardware techniques. Individuals working with the facility developed the idea of implementing phase retrieval by breaking the determination of the tip/tilt of each mirror apart from the piston motion (or translation) of each mirror. Presented in this report is an algorithm that determines the optimal phase correction associated only with the piston motion of the mirrors.
