The past decade has seen ever-increasing attention and resources dedicated to the application and operation of unmanned aircraft systems (UASs). Beginning with issuance of special airworthiness certificates in the experimental category for unmanned aircraft in 2007, up to the Federal Aviation Administration’s (FAA’s) Modernization and Reform Act of 2012 and creation of Title 14 Code of Federal Regulations (CFR) §107 and §101, the complexity and breadth of applications for UAS technology have flourished.

Recognizing the interest and potential benefits to the surface transportation community the National Cooperative Highway Research Program (NCHRP) commissioned Scan 17-01 to accelerate beneficial innovation by facilitating …

Measuring Public Utilization Perception Potential Of Unmanned Aircraft Systems, Julius Keller, Daniel Kwasi Adjekum, Bortiorkor Nii Tsui Alabi, Brian Kozak

Aviation Faculty Publications

The integration of Unmanned Aircraft Systems (UAS) into the National Air Space (NAS) in recent times has been met by mixed public responses. The paper establishes four constructs each of which encapsulates multiple backgrounds and concerns of the stakeholders: functional knowledge, utilization trust, operational integration support, and safety risk-benefits. The paper hypothesizes that these constructs can serve as underlying components for a research instrument namely, the Public Utilization Perception Potential (PUPP) which can be used to assess the opinions of the public on UAS integration into NAS. Responses from the public on items in a beta-tested survey instrument were analyzed …

Comparison Of Autonomic Control Of Blood Pressure During Standing And Artificial Gravity Induced Via Short-Arm Human Centrifuge, Ajay K. Verma, Da Xu, Michelle Bruner, Amanmeet Garg, Nandu Goswami, Andrew P. Blaber, Kouhyar Tavakolian

Electrical Engineering Faculty Publications

Autonomic control of blood pressure is essential toward maintenance of cerebral perfusion during standing, failure of which could lead to fainting. Long-term exposure to microgravity deteriorates autonomic control of blood pressure. Consequently, astronauts experience orthostatic intolerance on their return to gravitational environment. Ground-based studies suggest sporadic training in artificial hypergravity can mitigate spaceflight deconditioning. In this regard, short-arm human centrifuge (SAHC), capable of creating artificial hypergravity of different g-loads, provides an auspicious training tool. Here, we compare autonomic control of blood pressure during centrifugation creating 1-g and 2-g at feet with standing in natural gravity. Continuous blood pressure was acquired …

A Systematic Literature Review For Evidence Of Aphanizomenon Flos-Aquae Toxigenicity In Recreational Waters And Toxicity Of Dietary Supplements: 2000–2017, Amber Lyon-Colbert, Shelley Su, Curtis Cude

Kinesiology & Public Health Education Faculty Publications

Previous studies of recreational waters and blue-green algae supplements (BGAS) demonstrated co-occurrence of Aphanizomenon flos-aquae (AFA) and cyanotoxins, presenting exposure risk. The authors conducted a systematic literature review using a GRADE PRISMA-p 27-item checklist to assess the evidence for toxigenicity of AFA in both fresh waters and BGAS. Studies have shown AFA can produce significant levels of cylindrospermopsin and saxitoxin in fresh waters. Toxicity studies evaluating AFA-based BGAS found some products carried the mcyE gene and tested positive for microcystins at levels ≤ 1 μg microcystin (MC)-LR equivalents/g dry weight. Further analysis discovered BGAS samples had cyanotoxins levels exceeding tolerable …

Assessing The Challenges Of Surface‐Level Aerosol Mass Estimates From Remote Sensing During The Seac4rs And Search Campaigns: Baseline Surface Observations And Remote Sensing In The Southeastern United States, Katie C. Kaku, J. S. Reid, Jenny Hand, E. S. Edgerton, B. N. Holben, Jianglong Zhang, R. E. Holz

Atmospheric Sciences Faculty Publications

The Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) campaign conducted in the southeast United States (SEUS) during the summer of 2013 provided a singular opportunity to study local aerosol chemistry and investigate aerosol radiative properties and PM2.5 relationships, focusing on the complexities involved in simplifying the relationship into a linear regression. We utilize three Southeastern Aerosol Research and Characterization network sites and one Environmental Protection Agency Chemical Speciation Network station that afforded simultaneous Aerosol Robotic Network (AERONET) aerosol optical depth (AOD) and aerosol mass, chemistry, and light scattering monitoring. Prediction of AERONET AOD …

Borrelia Burgdorferi Adhere To Blood Vessels In The Dura Mater And Are Associated With Increased Meningeal T Cells During Murine Disseminated Borreliosis, Ali Divan, Timothy Casselli, Anand Narayanan, Sanjib Mukherjee, David C. Zawieja, John A. Watt, Catherine A. Brissette, Karen Newell-Rogers

Biomedical Sciences Faculty Publications

Borrelia burgdorferi, the causative agent of Lyme disease, is a vector-borne bacterial infection that is transmitted through the bite of an infected tick. If not treated with antibiotics during the early stages of infection, disseminated infection can spread to the central nervous system (CNS). In non-human primates (NHPs) it has been demonstrated that the leptomeninges are among the tissues colonized by B. burgdorferi spirochetes. Although the NHP model parallels aspects of human borreliosis, a small rodent model would be ideal to study the trafficking of spirochetes and immune cells into the CNS. Here we show that during early and late …

Chemistry Faculty Publications

Background: Exposure to traffic-derived particulate matter (PM), such as diesel exhaust particles (DEP), is a leading environmental cause of cardiovascular disease (CVD), and may contribute to endothelial dysfunction and development of atherosclerosis. It is still debated how DEP and other inhaled PM can contribute to CVD. However, organic chemicals (OC) adhered to the particle surface, are considered central to many of the biological effects. In the present study, we have explored the ability of OC from DEP to reach the endothelium and trigger proinflammatory reactions, a central step on the path to atherosclerosis.

Results: Exposure-relevant concentrations of DEP (0.12 μg/cm2 …

Lipophilic Chemicals From Diesel Exhaust Particles Trigger Calcium Response In Human Endothelial Cells Via Aryl Hydrocarbon Receptor Non-Genomic Signalling, Alena Kubatova, Bendik C. Brinchmann, Eric Le Ferrec, Normand Podechard, Dominique Lagadic-Gossmann, Kenji F. Shoji, Aubin Penna, Klara Kukowski, Jorn A. Holme, Johan Ovrevik

Chemistry Faculty Publications

Exposure to diesel exhaust particles (DEPs) affects endothelial function and may contribute to the development of atherosclerosis and vasomotor dysfunction. As intracellular calcium concentration [Ca²⁺]_i is considered important in myoendothelial signalling, we explored the effects of extractable organic matter from DEPs (DEP-EOM) on [Ca²⁺]_i and membrane microstructure in endothelial cells. DEP-EOM of increasing polarity was obtained by pressurized sequential extraction of DEPs with n-hexane (n-Hex-EOM), dichloromethane (DCM-EOM), methanol, and water. Chemical analysis revealed that the majority of organic matter was extracted by the n-Hex- and DCM-EOM, with polycyclic aromatic hydrocarbons primarily occurring in n-Hex-EOM. …

Differences In The Type And Sequence Order Of Self-Defense Behaviors During A High-Risk Victimization Scenario: Impact Of Prior Sexual Victimization, Raeann E. Anderson, Shawn P. Cahill, Douglas L. Delahanty

Psychology Faculty Publications

Objective: During a potential sexual assault experience, an active, assertive behavioral response to threat (BRTT) can be protective while a non-assertive BRTT may increase risk. However, little is known about how the sequence of behaviors that a woman engages in during a threatening situation may be related to sexual victimization. The present study investigated the style and sequence of behaviors in college women’s behavioral response to threat using a lab-based date rape self-defense scenario.

Method: 135 college women (113 with a history of sexual victimization) completed a lab-based self-defense scenario in which the threat stimuli and situational context were standardized. …
