The Effects Of The Urban Environment On Background Neutron Flux, Eric Reddick, John Burkhardt, Marshall Millett

Purdue Workshop on Nonproliferation: Technology and Approaches

This project will measure the neutron background inan urban environment using United States Naval Academy’s(USNAs)high sensitivity neutron detection system, called the Large Neutron Sensor (LNS).The background neutron flux represents noise and affects our ability to identify a signal from illicit source material, including plutonium.As the neutron background essentially rains down from high energy cosmic ray events in our upper atmosphere, the shielding effect of skyscrapers in an urban environment on the ground level background is of interest.Witha characterization of the neutron background in this environment, end users will be able to optimize the effectiveness of survey protocols and alarm algorithms.

A Characterization Of Undersea Neutron And Capture Gamma Signatures Resulting From Special Nuclear Material On A Maritime Vessel, Elizabeth Troy

Purdue Workshop on Nonproliferation: Technology and Approaches

Special Nuclear Materials (SNM) located aboard ships emit radiation that may be detectable in the undersea environment. An Unmanned Underwater Vehicle (UUV) could be equipped with detection capabilities to determine whether commercial or private vessels are carrying SNM prior to reaching port. Additional research is needed improve such a UUV’s ability to detect and discriminate between types of SNM and reduce false- positive detections. This research builds on past work by C. T. McKay to provide a higher fidelity characterization of detectable radiation signatures from SNM in the undersea environment with a focus on plutonium-bearing SNM. 252Cf will be used …

The Notorious Ben Hecht: Iconoclastic Writer And Militant Zionist, Julien Gorbach

Purdue University Press Book Previews

Ben Hecht had seen his share of death-row psychopaths, crooked ward bosses, and Capone gun thugs by the time he had come of age as a crime reporter in gangland Chicago. His grim experience with what he called “the soul of man” gave him a kind of uncanny foresight a decade later, when a loose cannon named Adolf Hitler began to rise to power in central Europe.

In 1932, Hecht solidified his legend as "the Shakespeare of Hollywood" with his thriller Scarface, the Howard Hughes epic considered the gangster movie to end all gangster movies. But Hecht rebelled against his …

Exploring Laser Induced Breakdown Spectroscopy (Libs) For Post-Detonation Nuclear Forensics Debris Analysis, Justin Knoll, Chad Schools, David Fobar

Purdue Workshop on Nonproliferation: Technology and Approaches

In the unlikely but catastrophic event of a nuclear terrorist attack our government leadership will need reliable information to rapidly inform critical decisions. This research explores the use of Laser Induced Breakdown Spectroscopy (LIBS) as a potential analysis tool in the National Technical Nuclear Forensics process. The current state of post detonation nuclear forensics requires ground and air samples be collected and shipped to state-of-the-art laboratories for radiochemical analysis. The samples undergo many measurements and useable data is produced as these measurements are completed. This data flows back into the process to guide additional measurements and inform the process of …

Radiation Detection, Measurement, And Visualization Assisted By Virtual And Augmented Reality, Erik Medhurst, Rizwan Uddin

Purdue Workshop on Nonproliferation: Technology and Approaches

Localizing a radiation source in an urban environment is a challenge in nuclear nonproliferation and radiation detection. Mobile radiation sensor networks can be sent into an area of interest to collect count rate measurements at many locations in an attempt to find the radiation source. However, there are numerous factors that cause fluctuations in background count rate such as time and location, and these factors make it challengingto analyze thecollected data. Displaying these measurements in a virtual model has contextualized them and made it easier to determine if environmental factors are introducing false positives. A virtual model has been shown …

Purdue Conference On Active Nonproliferation, Angela Di Fulvio, Yoann Altma, Marc G. Paff, Al Hero, Sara A. Pozzi

Purdue Workshop on Nonproliferation: Technology and Approaches

One major problem with nuclear security measurements involves source identification inthe presence of low signal-to-background ratio. This scenario iscommon to several applications, ranging from radiation identification atportal monitors to radiation source search with unmanned vehicles. In this context of identification of a large variety of sources, including natural and medical sources, sensitive sources of particular interest, but also potentially new/unknown sources for which no reference measurement is available, statistical methods are particularly appealing for their ability to capture the random nature of the measurements. Among them, Bayesian methods form a generic framework allowing for uncertainty quantification and propagation, which is …

A Theoretical Model Of Underground Dipole Antennas For Communications In Internet Of Underground Things, Abdul Salam, Mehmet C. Vuran, Xin Dong, Christos Argyropoulos, Suat Irmak

Faculty Publications

The realization of Internet of Underground Things (IOUT) relies on the establishment of reliable communication links, where the antenna becomes a major design component due to the significant impacts of soil. In this paper, a theoretical model is developed to capture the impacts of change of soil moisture on the return loss, resonant frequency, and bandwidth of a buried dipole antenna. Experiments are conducted in silty clay loam, sandy, and silt loam soil, to characterize the effects of soil, in an indoor testbed and field testbeds. It is shown that at subsurface burial depths (0.1-0.4m), change in soil moisture impacts …

Cambodian American Views Of Partnerships In Public Education, Peter T. Keo

Journal of Southeast Asian American Education and Advancement

This study elicited the views of Cambodian American adults regarding public school partnerships. The central argument is that the paucity of extant literature and research on Southeast Asian American (SEAA) family-school partnerships in public education renders these individuals invisible. Given the fluid and dynamic lived experiences across and within the SEAA community, there is a critical need for empirical research that addresses issues particular to ethnic groups. Surveys and semi-structured interviews were utilized to collect data from Cambodian American respondents. Findings suggested the importance of culture and structure in building critical partnerships.

A Critical Evaluation Of Trpa1-Mediated Locomotor Behavior In Zebrafish As A Screening Tool For Novel Anti-Nociceptive Drug Discovery, Meejung Ko, Logan C. Ganzen, Emre Coskun, Arbaaz Mukadam, Yuk Fai Leung, Richard Van Rijn

Purdue University Libraries Open Access Publishing Fund

Current medications inadequately treat the symptoms of chronic pain experienced by over 50 million people in the United States, and may come with substantial adverse effects signifying the need to find novel treatments. One novel therapeutic target is the Transient Receptor Potential A1 channel (TRPA1), an ion channel that mediates nociception through calcium influx of sensory neurons. Drug discovery still relies heavily on animal models, including zebrafish, a species in which TRPA1 activation produces hyperlocomotion. Here, we investigated if this hyperlocomotion follows zebrafish TRPA1 pharmacology and evaluated the strengths and limitations of using TRPA1-mediated hyperlocomotion as potential preclinical screening tool …

Energy Reports

Indiana’s climate and its manufacturing-heavy economy make it a prime user of energy. In fact, Indiana is the ninth-most energy intensive state per capita in the country.

Nearly three-quarters of Indiana’s electricity comes from coal, and 5 percent is generated by renewable sources, though the wind energy sector is growing and coal use is declining. This energy mix makes the Hoosier State the eighth-largest emitter of climate-changing gases, at 183 million metric tons of carbon dioxide (CO₂) emitted per year.

As global and local climates continue to shift, it is important to know how Indiana’s future energy profile …
