The Role Of The Fda In Innovation Policy, Rebecca S. Eisenberg Jan 2007

The Role Of The Fda In Innovation Policy, Rebecca S. Eisenberg

Michigan Telecommunications & Technology Law Review

This Article reexamines the role of FDA regulation in motivating investment in biopharmaceutical innovation. I begin by challenging the standard story that it is the patent system that makes drug development profitable, and drug regulation that makes it costly, by showing how patents add to costs and how drug regulation works in tandem with patents to protect profits. I then compare FDA-administered exclusive rights to patents as a means of fortifying drug development incentives, suggesting ways that FDA-administered rights might be preferable both from the perspective of policy makers and from the perspective of firms. In the remainder of the …

Increasing Energy Efficiency Through Improvements In Ladle Materials And Practices, Kent D. Peaslee, Semen Naumovich Lekakh, Jeffrey D. Smith, Mangesh Vibhandik Jan 2007

Increasing Energy Efficiency Through Improvements In Ladle Materials And Practices, Kent D. Peaslee, Semen Naumovich Lekakh, Jeffrey D. Smith, Mangesh Vibhandik

Materials Science and Engineering Faculty Research & Creative Works

Steel foundry ladle practices play an important role in total energy efficiency of melting as well as influence casting quality. Extensive heat losses in the ladle could be associated with excessive superheating of the melt before tap which increases energy consumption, promotes oxidation of the melt and increases refractory consumption. A high cooling rate of the liquid metal in the ladle could also cause casting quality instability. The overall ladle heat balance and components of heat losses were analyzed using FLUENT and FACTSAGE software and validated with experimental data from both the UMR foundry and industrial foundries. The purpose of …

Enhanced Electronic Conductivity In Si-Substituted Calcium Aluminate, Julia E. Medvedeva, Thomas O. Mason, Kenneth R. Poeppelmeier, Mariana I. Bertoni, Arthur J. Freeman Jan 2007

Enhanced Electronic Conductivity In Si-Substituted Calcium Aluminate, Julia E. Medvedeva, Thomas O. Mason, Kenneth R. Poeppelmeier, Mariana I. Bertoni, Arthur J. Freeman

Physics Faculty Research & Creative Works

Improved conductivity has been achieved by controllable substitution of an ultraviolet electronic conductor. The transparent conducting oxide system, H-doped Ca12Al(14−x)SixO(33+x/2) with x=0−4, exhibits a conductivity strongly dependent on the substitution level. Four-point direct current conductivity increases with x from 0.15 to 0.61 S/cm at room temperature. The observed conductivity behavior is consistent with the predictions of our first principles density functional calculations for the Si-substituted system with x=0, 2, and 4. Furthermore, the Seebeck coefficient is composition dependent suggesting the existence of an activated mobility associated with small polaron conduction. ©2007 American Institute of Physics

Differential Double Capture Cross Sections In P+He Collisions, Michael Schulz, T. Vajnai, J. A. Brand Jan 2007

Differential Double Capture Cross Sections In P+He Collisions, Michael Schulz, T. Vajnai, J. A. Brand

Physics Faculty Research & Creative Works

We have measured differential double capture cross sections for 15 to 150 keV p+He collisions. We also analyzed differential double to single capture ratios, where we find pronounced peak structures. An explanation of these structures probably requires a quantum-mechanical description of elastic scattering between the projectile and the target nucleus. Strong final-state correlations have a large effect on the magnitude of the double capture cross sections

The Use Of Thermoelectric Peltiers To Recapture Waste Heat, Navarre Bartz Jan 2007

The Use Of Thermoelectric Peltiers To Recapture Waste Heat, Navarre Bartz

Opportunities for Undergraduate Research Experience Program (OURE)

Peltier devices are a method of converting differences in temperature into electrical energy. Using data from a supplier of these devices, calculations were made to determine the efficiency of these devices in conjunction with a residential solar hybrid electric system. The initial calculations show efficiencies less than 2% with the temperature differences experienced during the springtime. While this efficiency doesn't sound stellar, taking into account the current efficiency of residential solar cells, this would be an appreciable addition to the power output of a residential solar system.

Computational Study Of Laminar Separation Bubble Development Over Supersonic Airfoils At Subsonic Speeds, Josiah D. Elliott

Opportunities for Undergraduate Research Experience Program (OURE)

Laminar Separation Bubbles (LSBs) are regions of separated flow that start near the leading edge of an airfoil and reattach further down the airfoil surface. These regions of separation can appear at low angles of attack and can grow significantly as the angle of attack is increased heavily influencing the flow characteristics over the airfoil. Research on this topic is driven by the supersonic business jet industry which has a particular interest in this type of research due to performance requirements in both the subsonic and supersonic flight regimes. This manuscript is focused on the flow developments near the sharp …

Telangiectasia Detection In Dermoscopy Images, David Erdos

Opportunities for Undergraduate Research Experience Program (OURE)

Melanoma lesions that exhibit irregular linear vessels can be misdiagnosed due to the fact that their clinical appearance can often closely resemble other skin conditions. Detection these irregular linear blood vessels, or telangiectasia could improve the accuracy of melanoma diagnosis. An algorithm that detects telangiectasia has been developed; it initially searches for color drops in an image in various directions and then uses various post processing techniques to improve the accuracy. The feasibility of using classifiers such as neural networks to further improve the accuracy has also been investigated.

Three-Dimensional Structure Of Cdx (X= Se, Te) Nanocrystals By Total X-Ray Diffraction, S. K. Pradhan, Z. T. Deng, F. Tang, Y. Ren, Peter Moeck, V. Petkov Jan 2007

Three-Dimensional Structure Of Cdx (X= Se, Te) Nanocrystals By Total X-Ray Diffraction, S. K. Pradhan, Z. T. Deng, F. Tang, Y. Ren, Peter Moeck, V. Petkov

Physics Faculty Publications and Presentations

The three-dimensional structure of oleic acid-capped CdSe and thiol-capped CdTe nanocrystals used as quantum dots has been determined by total synchrotron radiationx-ray diffraction and atomic pair distribution function analysis. Both CdSe and CdTe are found to exhibit the zinc-blende-type atomic ordering. It is only slightly distorted in CdSe implying the presence of nanosize domains and very heavily distorted in CdTe due to the presence of distinct core-shell regions. The results well demonstrate the great potential of the experimental approach and thus encourage its wider application in quantum dot research.

Preparation Of Bioactive Glasses With Controllable Degradation Behavior And Their Bioactive Characterization, Aihua Yao, Deping Wang, Qiang Fu, M. N. Rahaman, Wen-Hai Huang

Materials Science and Engineering Faculty Research & Creative Works

Bioactive glasses and ceramics have been widely investigated for bone repair because of their excel-lent bioactive characteristics. However, these biomaterials undergo incomplete conversion into a bone-like material, which severely limits their biomedical application. In this paper, borosilicate bioac-tive glasses were prepared by traditional melting process. The results showed that borosilicate glasses possessed high biocompatibility and bioactivity. In addition, when immersed in a 0.02 mol/L K2HPO4 solution, particles of a borate glass were fully converted to HA. The desirable conversion rate to HA may be achieved through the adjustment of the B2O3/SiO2 ratio. The results of XRD and FTIR analysis indicated …

Qualitative Data Analysis: Comparison Between Traditional And Computerized Text Analysis, Melissa A. Bright, Dawn O’Connor

All Volumes (2001-2008)

Most often quantitative data is used in the social sciences. Sometimes, however, researchers must use qualitative data for exploration. In a study on communication effectiveness we used both quantitative and qualitative data. After analyzing the quantitative data we used both a traditional text analysis and a computerized text analysis. Our aim in this paper is to discuss variance, or lack thereof, between outcomes utilizing traditional and computerized text analysis.

Methods To Improve Bond On Frp Wrapped Piles, Andy Schrader Jan 2007

Methods To Improve Bond On Frp Wrapped Piles, Andy Schrader

USF Tampa Graduate Theses and Dissertations

Fiber Reinforced Polymer (FRP) sheets can provide incredible structural strength while weighing only a fraction as much as steel. When applied to piles the FRP provides strengthening through both concrete confinement and tensile reinforcement. Mainly used in structural repair, its application is relatively simple in theory. However, many factors(some avoidable, some not) can interfere with the bond between FRP and concrete. When this bond is interrupted the strength of the repair becomes compromised.This thesis examines 2 new methods of improving FRP bond to concrete piles during the time the resin is curing. These methods are compared using 3 types of …

Vadose Zone Processes Affecting Water Fluctuations: Conceptualization And Modeling Considerations, Nirjhar Shah Jan 2007

Vadose Zone Processes Affecting Water Fluctuations: Conceptualization And Modeling Considerations, Nirjhar Shah

USF Tampa Graduate Theses and Dissertations

This dissertation focuses on a variety of vadose zone processes that impact water table fluctuations. The development of vadose zone process conceptualization has been limited due to both the lack of recognition of the importance of the vadose zone and the absence of suitable field data. Recent studies have, however, shown that vadose zone soil moisture dynamics, especially in shallow water table environments, can have a significant effect on processes such as infiltration, recharge to the water table, and evapotranspiration. This dissertation, hence, attempts to elucidate approaches for modeling vadose zone soil moisture dynamics. The ultimate objective is to predict …

Cellular Electrofusion Utilizing Corona Fields And Dc Pulse Technology, Joshua Stein Jan 2007

Cellular Electrofusion Utilizing Corona Fields And Dc Pulse Technology, Joshua Stein

USF Tampa Graduate Theses and Dissertations

Cell fusion is an important technique that is used in the field of medicine and biomedical research. For instance, fusion can be used to create hybridomas and novel types of secretory hybrid cells. It may also be used to engineer cultured insulin-secreting pancreatic B-cell lines for the treatment of diabetes. Historically, the applications listed above have been accomplished by a number of methodologies including dielectrophoresis, centrifugation, polyethylene glycol (PEG) and viral fusion proteins. However, these approaches often fail to produce the desired results due to poor cell viability, lack of 1:1 fusion, and use of non-physiological environments. It is proposed …

Pneumatic Tool Hand-Arm Vibration And Posture Characterization Involving U.S. Navy Shipboard Personnel, Charles R. Wilhite

USF Tampa Graduate Theses and Dissertations

The United States Navy incorporates many different occupations to ensure it achieves its overall mission. These occupations are extremely diversified and present a wide spectrum of occupational exposures. Many of these exposures have been well studied and documented. However, shipboard pneumatic tool hand-arm vibration, (HAV) and how it relates to different body postures is an area of occupational exposure that has received little attention. The chief objective of this study was to assess whether there is a difference in hand-arm vibration levels, while working on one of two surface orientations (e.g., horizontal and vertical) among distinctly different pneumatic tools while …

Graduate Students/Mothers Negotiating Academia And Family Life: Discourses, Experiences, And Alternatives, Shirlan A. Williams Jan 2007

Graduate Students/Mothers Negotiating Academia And Family Life: Discourses, Experiences, And Alternatives, Shirlan A. Williams

USF Tampa Graduate Theses and Dissertations

This study examines the experiences and perceptions of graduate students who are mothers. Based on discourse analysis, one-on-one interviews, and focus groups, this study argues that institutional discourses and practices place graduate students who are mothers in untenable and irreconcilable positions between "mom" and "student," between "family" and "the academy," between "self" and "success." These irreconcilable differences are created in discourse, enacted in institutional policies, and lived by the participants. The study offers action-based alternatives to the status quo policies of the university based on the self-described needs of these women. It reveals that support from all fronts--the home, the …
