The Effect Of Ischemia Reperfusion On Intestinal Contractility Regulated By The Nitrergic System, Fatma Çağlayan, Ayşe Şahi̇n, Engi̇n Günel, Murat Çakmak, Osman Çağlayan Jan 2004

The Effect Of Ischemia Reperfusion On Intestinal Contractility Regulated By The Nitrergic System, Fatma Çağlayan, Ayşe Şahi̇n, Engi̇n Günel, Murat Çakmak, Osman Çağlayan

Turkish Journal of Veterinary & Animal Sciences

Because of the interaction between nitric oxide (NO) and the superoxide anion radical, the effect of ischemia-reperfusion on intestinal contractility regulated by the nitrergic system was investigated in the present study. The study was performed on 3 groups of rabbits: group 1, ischemia; group 2, ischemia and 1 h of reperfusion; group 3, ischemia and 24 h of reperfusion. Tissue samples were obtained from ischemic, ischemia-reperfused and adjacent uninjured intestines as study and control samples. The effects of atropine, tetrodotoxin, L-NAME and L-arginine on the intestinal response to electrical field stimulation (EFS) were investigated. Guanethidine was used to minimize adrenergic …

Law School Education In The 21st Century: Adding Information Technology Instruction To The Curriculum, Kenneth J. Hirsh, Wayne V. Miller Jan 2004

Law School Education In The 21st Century: Adding Information Technology Instruction To The Curriculum, Kenneth J. Hirsh, Wayne V. Miller

Faculty Scholarship

For the past 120 years, legal education in the United States has been fundamentally unchanged, even while the practice of law has been revolutionized by information technology. The ideal of the Socratic Method is still dominant in first year and many upperclass courses. Clinical and practice courses have expanded since the early-1980s; however, although state-of-the-art technology is now commonplace in law offices, most federal courthouses, and some state courtrooms, until now, there has been little effort to contextualize the importance of technology for law students. The authors review the availability of courses covering use of technology in law practice at …

Experimental Simulations And Tort Reform: Avoidance, Error And Overreaching In Sunstein Et Al.’S ‘Punitive Damages’, Neil Vidmar Jan 2004

Experimental Simulations And Tort Reform: Avoidance, Error And Overreaching In Sunstein Et Al.’S ‘Punitive Damages’, Neil Vidmar

Faculty Scholarship

This article addresses tort reform claims made in Cass R. Sunstein, et al.'s Punitive Damages: How Juries Decide (2002)and related articles, research that was largely underwritten by the Exxon Corporation. Based upon a series of simulation experiments, those authors have made a general claim that juries are incapable of making coherent judgments about punitive damages. In this article I raise serious methodological problems bearing on the validity of the research, and, therefore, its ability to provide judges and legislators with useful information about juries and punitive damages.

Fear Assessment: Cost-Benefit Analysis And The Pricing Of Fear And Anxiety, Matthew D. Adler Jan 2004

Fear Assessment: Cost-Benefit Analysis And The Pricing Of Fear And Anxiety, Matthew D. Adler

Faculty Scholarship

Risk assessment is now a common feature of regulatory practice, but fear assessment is not. In particular, environmental, health and safety agencies such as EPA, FDA, OSHA, NHTSA, and CPSC, commonly count death, illness and injury as costs for purposes of cost-benefit analysis, but almost never incorporate fear, anxiety or other welfare-reducing mental states into the analysis. This is puzzling, since fear and anxiety are welfare setbacks, and since the very hazards regulated by these agencies - air or water pollutants, toxic waste dumps, food additives and contaminants, workplace toxins and safety threats, automobiles, dangerous consumer products, radiation, and so …

Colorization Revisited, Julie C. Van Camp Jan 2004

Colorization Revisited, Julie C. Van Camp

Contemporary Aesthetics (Journal Archive)

This article is both philosophical and practical in its intent. It endeavours to bring into focus an idea with an Ancient Greek lineage, poiesis, and determine whether it may revitalise our thinking about the 'making' of art. The art-making considered in this paper will concentrate exclusively on Western art and its historical and contemporary manifestations. I suggest that poiesis - that which "pro-duces or leads (a thing) into being'" - may enable practitioners in the varying art forms, and aestheticians who reflect upon them, to come to a deeper sense of how artworks work: that they realize themselves inter-dependently …

Real-Time 4d Tumor Tracking And Modeling From Internal And External Fiducials In Fluoroscopy, Johanna Brewer, Margrit Betke, David P. Gierga, George T.Y. Chen Jan 2004

Real-Time 4d Tumor Tracking And Modeling From Internal And External Fiducials In Fluoroscopy, Johanna Brewer, Margrit Betke, David P. Gierga, George T.Y. Chen

Computer Science: Faculty Publications

Fluoroscopy is currently used in treatment planning for patients undergoing radiation therapy. Radiation oncologists would like to maximize the amount of dose the tumor receives and minimize the amount delivered to the surrounding tissues. During treatment, patients breathe freely and so the tumor location will not be fixed. This makes calculating the amount of dose delivered to the tumor, and verifying that the tumor actually receives that dose, difficult. We describe a correlation- based method of tracking the two-dimensional (2D) motion of internal markers (surgical clips) placed around the tumor. We established ground truth and evaluated the accuracy of the …

Neutrality Agreements And Card Check Recognition: Prospects For Changing Paradigms , James J. Brudney Jan 2004

Neutrality Agreements And Card Check Recognition: Prospects For Changing Paradigms , James J. Brudney

Faculty Scholarship

The rise of neutrality agreements is a major development in labor-management relations in this country. The union movement's new approach to organizing displaces elections supervised by the National Labor Relations Board (NLRB) with negotiated agreements that provide for employers to remain neutral during an upcoming union campaign and (in most instances) for employees to decide if they wish to be represented through signing authorization cards rather than through a secret ballot election. Professor Brudney demonstrates the substantial role now being played by this contractually based approach to union organizing. He also explains why so many employers have agreed to neutrality …

A Highway Travel Information System: Forecasting And Publicizing Delays In The Indiana State Highway Network, Shu-Ling Yu, Jon D. Fricker Jan 2004

A Highway Travel Information System: Forecasting And Publicizing Delays In The Indiana State Highway Network, Shu-Ling Yu, Jon D. Fricker

JTRP Technical Reports

The Highway Travel Information System (HTIS) is a long-term pre-trip information system providing information about expected events, such as road construction. The HTIS can be beneficial to both highway travelers and roadway project schedulers. Project schedulers can use the HTIS to check the forecasted traffic impacts of a proposed construction project schedule. If the schedule would cause unacceptable delays, a scheduler can try new schedules to reduce the delay. Travelers who have flexible schedules and would like to do pre-trip planning can obtain knowledge of traffic conditions in the near future from HTIS to avoid unnecessary delays. An approach called …

Constructability, Maintainability, And Operability Of Fiber Reinforced Polymer (Frp) Bridge Deck Panels, Makarand Hastak, Daniel W. Halpin, Taehoon Hong

JTRP Technical Reports

Recent advances in composite materials for civil engineering have created interesting possibilities for replacing conventional structural forms with components made out of fiber reinforced composite materials. Composite materials offer several advantages over conventional materials such as a superior strength/weight ratio, a better stiffness/weight ratio, a high degree of chemical inertness, and flexible custom design characteristics. Some of the potential down-stream benefits include lower life-cycle costs, lighter members, high corrosion and fatigue resistance, and higher live load capacity (Seible and Karbhari 1996). Composite materials are clearly having a major impact on how facilities are designed, constructed, and maintained. In order to …

Development Of Indiana's Sps9-A Site, Ayesha Shah, J. Olek Jan 2004

Development Of Indiana's Sps9-A Site, Ayesha Shah, J. Olek

JTRP Technical Reports

The Superpave system for hot mix asphalt (HMA) design was introduced in 1995 and adopted throughout most of the USA by 2000. This system uses performance-oriented approach to materials selection and mix design, and takes into account the local environmental and traffic conditions. It recognizes that the behavior of HMA depends on the temperature, loading and aging conditions and provides tools (in the form of materials selection and performance-related tests) that should help to protect pavements against low-temperature cracking, rutting and fatigue cracking. This report summarizes the field and laboratory studies conducted to investigate the influence of asphalt binder grade …

Evaluation Of Indot Construction Smoothness Specifications, Terhi K. Pellinen, Shao-Fan Chou Jan 2004

Evaluation Of Indot Construction Smoothness Specifications, Terhi K. Pellinen, Shao-Fan Chou

JTRP Technical Reports

Currently, Indiana Department of Transportation (INDOT) is using the California Profilograph as the standard measuring device in its smoothness specifications. The output derived from the profilograph is called Profile Index (PI). PI represents the total accumulated deviations of the profilograph output traces beyond a tolerance zone (blanking band). At present, INDOT is using 0.2-inch blanking band to evaluate the profile traces, which has raised some concerns because some small unpleasant surface irregularities are covered by the blanking band. The major objective of this study was to develop a rational method for interpreting profilograph traces using 0.0-inch blanking band (zero tolerance) …

Innovative Environmental Management Of Winter Salt Runoff Problems At Indot Yards, James E. Alleman, Barry K. Partridge, Lee Yeung Jan 2004

Innovative Environmental Management Of Winter Salt Runoff Problems At Indot Yards, James E. Alleman, Barry K. Partridge, Lee Yeung

JTRP Technical Reports

This INDOT-JTRP project examined an innovative strategy for mitigating, and possibly obviating, the environmental impact of wintertime salt release within INDOT yard areas specifically associated with the generation and release of salt truck wash waters, whereby these waste streams may be beneficially reused in the manufacture of salt brine solutions suitable for subsequent pre-wetting and anti-icing applications. The associated environmental problem stems from the fact that these wash waters carry high-level (e.g., from 100’s of mg/L to percentile-level) salt concentrations whose uncontrolled release via local surface or ground waters will have to be discontinued pursuant to the onset of tightened …

Interaction Between Micro-Cracking, Cracking, And Reduced Durability Of Concrete: Developing Methods For Considering Cumulative Damage In Life-Cycle Modeling, Zhifu Yang, W. Jason Weiss, J. Olek

JTRP Technical Reports

It is becoming increasingly popular to utilize numerical simulation models to predict the long-term performance of concrete pavements and structures. The majority of these models have been developed using laboratory test data that considers concrete in an uncracked state. While uncracked concrete exists as the best case scenario, frequent cracking occurs in real structures that could have a profound impact on life cycle performance. Cracks from several sources may accumulate and interact thereby accelerating the deterioration of concrete. For example, the distributed cracking caused by freeze/thaw damage can substantially increases the rate of water absorption and reduces the load carrying …

Limit States Design Of Deep Foundations, Kevin Christopher Foye, Grace Abou Jaoude, Rodrigo Salgado

JTRP Technical Reports

Load and Resistance Factor Design (LRFD) shows promise as a viable alternative to the present working stress design (WSD) approach to foundation design. The key improvements of LRFD over the traditional Working Stress Design (WSD) are the ability to provide a more consistent level of reliability and the possibility of accounting for load and resistance uncertainties separately. In order for foundation design to be consistent with current structural design practice, the use of the same loads, load factors and load combinations would be required. In this study, we review the load factors presented in various LRFD Codes from the US, …
