Development Of A Finite-Element Stored Grain Ecosystem Model, Michael D. Montross, Dirk E. Maier, Kamyar Haghighi

Biosystems and Agricultural Engineering Faculty Publications

An axisymmetric finite–element model was developed that predicts the heat, mass, and momentum transfer that occurred in upright corrugated steel storage structures due to conduction, diffusion, and natural convection using realistic boundary conditions. Weather data that included hourly total solar radiation, wind speed, ambient temperature, and relative humidity were used to model the temperature, moisture content, dry matter loss, and maize weevil development during storage with no aeration, and with ambient and chilled aeration. Periods of aeration were simulated assuming a uniform airflow rate through the grain mass. Heat and mass balances were used to calculate the temperature and absolute …

The literature was reviewed, crash data were obtained at nine case study bypasses, and discussions were held …

Defective Cd19-Dependent Signaling In B-1a And B-1b B Lymphocyte Subpopulations., Goutam Sen, Hsin-Jung Wu, Gabriel Bikah, Chandrasekar Venkataraman, Darrell A Robertson, E Charles Snow, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Peritoneal and pleural cavities in mice and humans contain a unique population of B-lymphocytes called B-1 cells that are defective in B cell antigen receptor (BCR) signaling but have an increased propensity to produce autoantibodies. Several molecules such as Btk, Vav, and CD19 known to be important for BCR signaling have been shown to be critical for the development of B-1 cells from undefined precursors. Here we demonstrate that B-1 cell unresponsiveness to BCR cross-linking is in part due to defective signaling through CD19, a molecule known to modulate signaling thresholds in B cells. The defective CD19 signaling is manifested …

Tort Liability For The Sale Of Non-Defective Products: An Analysis And Critique Of The Concept Of Negligent Marketing, Richard C. Ausness

Law Faculty Scholarly Articles

This Article will evaluate the concept of negligent marketing to see whether it ought to become a part of our legal jurisprudence or whether it should be discarded as doctrinally unsound, possibly harmful to important social and economic interests.

Part II of this Article provides an overview of the negligent marketing theory. Negligent marketing can be divided into three categories: (1) product designs that make the product more attractive to criminals; (2) advertising and promotional activities that target inappropriate users; and (3) product distribution practices that facilitate retail sales of dangerous products to vulnerable or unsuitable users. The first category …

Long-Term Benefits Of Stabilizing Soil Subgrades, Tommy C. Hopkins, Tony L. Beckham, Liecheng Sun, Bixian Ni, Barry Butcher

Kentucky Transportation Center Research Report

Chemical admixtures have been used extensively since the mid-eighties in Kentucky to improve bearing strengths of soil subgrades. Most pavements in Kentucky are constructed on clayey soils. Although short-term observations at a small number of sites showed that chemical stabilization worked very well, a need existed to perform a more comprehensive review and to assess the long-term benefits of this subgrade stabilization method. The main intent of this study was an attempt to address questions concerning bearing strengths, longevity, durability, structural credit, economics, and performance of pavements resting on soil subgrades mixed with chemical admixtures. In-depth field and laboratory studies …

Dust Emission From Active Galactic Nuclei, Maia Nenkova, Željko Ivezić, Moshe Elitzur

Physics and Astronomy Faculty Publications

Unified schemes of active galactic nuclei require an obscuring dusty torus around the central source, giving rise to a Seyfert 1 line spectrum for pole-on viewing and Seyfert 2 characteristics in edge-on sources. Although the observed IR is in broad agreement with this scheme, the behavior of the 10 μm silicate feature and the width of the far-IR emission peak remained serious problems in all previous modeling efforts. We show that these problems find a natural explanation if the dust is contained in approximately five to 10 clouds along radial rays through the torus. The spectral energy distributions of …

The numbers of students with disabilities enrolling in postsecondary institutions has increased since the passage of key disability rights legislation. As a result, the need for information about accommodating postsecondary students with disabilities has increased in the last two decades, especially since the passage of the Higher Education Amendments of 1998. This study used Dick and Carey's (1996) model of instructional design to conduct a formative evaluation of a Web-based performance support system (WPSS) designed for academic administrators, instructional employees, and auxiliary service administrators to enhance accommodations for postsecondary students with disabilities. Formative evaluation consisted of expert review, one-to-one, consumer …

Fiber Optic Sensor Response To High Levels Of Fat In Cream, Czarena L. Crofcheck, Frederick A. Payne, Clair L. Hicks, M. Pinar Mengüç, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

A light backscatter technique using optical fibers to deliver and receive light was investigated for measuring the milkfat content of unhomogenized cream. Light backscatter through cream at wavelengths of 450 to 900 nm was measured for fiber separation distances from 2 to 6.5 mm and for cream containing 10 to ~40 weight percent (wt%) milkfat. Unhomogenized cream (~40 wt% milkfat) was mixed with skim milk (~0.05 wt% milkfat) to yield samples with five different milkfat levels. Three optical response models were tested for correlation with milkfat content: one using the light intensity measurement at a single separation distance, the second …

The Hiv Protease Inhibitor Saquinavir Impairs Lipid Metabolism And Glucose Transport In Cultured Adipocytes, S. Ranganathan, Philip A. Kern

Clinical and Translational Science Faculty Publications

Treatment of HIV infection using protease inhibitors is frequently associated with lipodystrophy and impaired lipid and glucose metabolism. We examined the effect of saquinavir, one of the protease inhibitors, on lipid metabolism and glucose transport in cultured adipocytes. Saquinavir inhibited lipoprotein lipase (LPL) activity in 3T3-F442A and 3T3-L1 adipocytes. The inhibition of LPL was 81% at a concentration of 20 μg/ml. Another closely related drug, indinavir, had a small inhibitory effect. Saquinavir also inhibited the biosynthesis of lipids from [¹⁴C]-acetate. Saquinavir increased the lipolysis. Saquinavir had no significant effect on the cellular protein synthesis or protein content. Saquinavir …

Long-Term Retention Of Electronic Theses And Dissertations, Thomas H. Teper, Beth Kraemer

Library Faculty and Staff Publications

This paper examines the increasing trend of universities to pursue electronic thesis and dissertation (ETD) programs. Although the goal of most programs is similar, procedural variations impact a program’s long-term success. As primary research generators, responsibility for providing long-term access to unique materials must be borne by universities. However, this responsibility is in conflict with many ETD program goals, such as increased access and ease of production.

A Qualitative Investigation For Designing Intermediate (Grades 4-6) Information Literacy Instruction: Integrating Inquiry, Mentoring, And On-Line Resources, Melissa Ruth Gibson

University of Kentucky Doctoral Dissertations

Information literacy has become a priority in education. Elementary school library media specialists daily encounter the dilemma of having to teach information literacy skills without having time to do it adequately. With the proliferation of computers in schools, the possibility exists that students could use web-based information literacy tutorials or guides when teachers or librarians are not available. This study examines fifth grade students' perceptions of using on-line, web-based assistance to help them work through a research process, the Big6 . Qualitative research was conducted in 1998-1999 with ten students of diverse background and reading ability who were ten or …

Will More Aggressive Marketing Practices Lead To Greater Tort Liability For Prescription Drug Manufacturers?, Richard C. Ausness

Law Faculty Scholarly Articles

Manufacturers of prescription drugs have begun to market their products more aggressively than they did in the past. These marketing efforts are not confined to health care professionals alone; pharmaceutical companies now engage in extensive direct-to-consumer advertising on radio and television, in the print media, and even on the Internet. While these promotional efforts no doubt increase sales, they may also lead to greater tort liability for drug-related injuries. The most likely theories of liability are failure to warn and negligent marketing. Liability for inadequate warnings will almost certainly increase if courts abandon the learned intermediary rule and require drug …

Fabrication Of Vertically Aligned Carbon Nanotubes And Horizontal Nano-Structures, Wenchong Hu

University of Kentucky Master's Theses

Fabrication of ordered anodic alumina nanopore arrays and anodization parameters including electrolyte, concentration, voltage, temperature and time have been investigated. Cobalt nanoparticles were electrodeposited at the bottom of the pores. Vertically aligned, open-tipped multi-walled carbon nanotube arrays of high density and uniformity were synthesized via a flame method on silicon substrates using a nanoporous template of anodized aluminum oxide. The diameter and length of the nanotubes are controlled by the geometry of the aluminum oxide template. It is the cobalt catalyst particles, not the porous aluminum templates, help the growth of carbon nanotubes through graphitization and bonding of carbon nanotubes …
