Development Of Protocols For Reuse Assessment Of Existing Foundations In Bridge Rehabilitation And Replacement Projects, Jeehee Lim, Rodrigo Salgado, Monica Prezzi, Yao Wang, Fei Han

JTRP Technical Reports

The existing foundations of a bridge can sometimes be reused. This may occur when a completely new bridge is built but also in bridge or superstructure widening projects. Reuse of existing foundations not only eliminates the costs associated with demolishing and disposing of old foundations, but also reduces the costs of the design and construction of new foundation elements. However, several challenges exist, including assessing the structural integrity, estimating the current capacity, estimating the remaining service life, and considering current design codes and specifications of the existing foundations, and clear guidelines for foundation reuse. The absence of foundation reuse guidelines …

Investigating Consistency Among Bridge Inspectors Using Simulated Virtual Reality Testbed, Mohammad Jahanshahi, Shirley J. Dyke, Luis David Fernandez Vasquez, Nikkhil Vijaya Sankar, Yu-Ting Huang

JTRP Technical Reports

The current condition of US infrastructure requires a data-driven, risk-based approach to asset management. In the case of bridges, inspectors in every state visit these structures and collect data, and based on the information they report, state departments evaluate bridge conditions, predict deterioration, and make repair and retrofit decisions. However, the capacity of inspectors for defect detection might vary due to several factors, such as the inspectors’ experience or eyesight, which results in differences when reporting their results. Through the development of a virtual reality (VR)-based testbed, the variability among inspectors in examination and documentation practices in steel and concrete …

Jews And Science, Sander L. Gilman

The Jewish Role in American Life: An Annual Review

Jews and Science examines the complicated relationship between Jewish identities and the evolving meanings of science throughout the history of Western academic culture. Jews have been not only the agents for study of things Jewish, but also the subject of examination by “scientists” across a range of disciplines, from biology and bioethics to anthropology and genetics. Even the most recent iteration of Jewish studies as an academic discipline—Israel studies—stresses the global cultural, economic, and social impact of Israeli science and medicine.

The 2022 volume of the Casden Institute’s Jewish Role in American Life series tackles a range of issues that …

A Summer Of Mass Murder: 1941 Rehearsal For The Hungarian Holocaust, George Eisen

Purdue University Press Books

Most accounts of the Holocaust focus on trainloads of prisoners speeding toward Auschwitz, with its chimneys belching smoke and flames, in the summer of 1944. This book provides a hitherto untold chapter of the Holocaust by exploring a prequel to the gas chambers: the face-to-face mass murder of Jews in Galicia by bullets.

The summer of 1941 ushered in a chain of events that had no precedent in the rapidly unfolding history of World War II and the Holocaust. In six weeks, more than twenty thousand Hungarian Jews were forcefully deported to Galicia and summarily executed. In exploring the fate …

A Framework For Multi-Dimensional Assessment Of The Impacts Of Overweight Vehicle Operations And A Corridor-Level Case Study, Maria Alicia Chung Li

Lyles School of Civil Engineering Graduate Student Reports

Ground freight transportation is essential for the economy of any region. The efficient movement of goods from one location to another connects businesses with suppliers and customers, that enhances commerce and ultimately boosts the economy. The high volume of freight that has been transported on the nation’s highway network has allowed the trucking industry to provide enormous socio-economic benefits. Unfortunately, these benefits come with some costs associated with the operation of overweight (OW) trucks, such as accelerated deterioration of highway pavement and bridge assets, and passenger and freight traffic safety degradation. Thus, to manage safety risk, traffic mobility, and infrastructure …

A New Gtseq Resource To Facilitate Multijurisdictional Research And Management Of Walleye Sander Vitreus, Peter T. Euclide, Wesley A. Larson, Matthew Bootsma, Loren M. Miller, Kim T. Scribner, Wendylee Stott, Chris C. Wilson, Emily K. Latch

Purdue University Libraries Open Access Publishing Fund

Conservation and management professionals often work across jurisdictional boundaries to identify broad ecological patterns. These collaborations help to protect populations whose distributions span political borders. One common limitation to multijurisdictional collaboration is consistency in data recording and reporting. This limitation can impact genetic research, which relies on data about specific markers in an organism's genome. Incomplete overlap of markers between separate studies can prevent direct comparisons of results. Standardized marker panels can reduce the impact of this issue and provide a common starting place for new research. Genotyping-in-thousands (GTSeq) is one approach used to create standardized marker panels for nonmodel …

Us Veterinarians’ Perceptions Of Discussing Covid-19 Vaccination With Animal Owners During Routine Visits, Randolph Duane Hubach, Rachel Tonne

Purdue University Libraries Open Access Publishing Fund

COVID-19 vaccination uptake is disproportionately lower among rural, politically conservative, and underserved individuals in the United States. Engaging this population requires leveraging unique potential human health advocates, like veterinarians. Between September and October 2021, 103 veterinarians responded to open-ended prompts to assess providers' willingness and potential barriers to discussing COVID-19 vaccination within a veterinary visit. Veterinarians perceived they had a public health role in providing reliable and accurate COVID-19 information, including information related to approved vaccines. However, veterinary practitioners were aware of numerous potential barriers to having such discussions within a clinical visit (e.g., scope of practice concerns, shifting focus …

The Price Of Longevity - Empirical Evidence From Road Pavements, Hanna Kemaw

Lyles School of Civil Engineering Graduate Student Reports

The vast network of county, city and town roads, represent a big part of public assets in most states and often account for a significant share of the public spending on roads. This spending on local road infrastructure help to build, operate, and preserve such infrastructure and therefore provide critical accessibility and mobility to the residents of counties, towns and cities. With the ever-growing volumes of personal and commercial traffic at local roads, the task of maintaining satisfactory levels of service at local roads has become more challenging, and this issue is exacerbated by limited resources, asset aging, and increasing …
