The contribution of elevated AOD-PM2.5 on respiratory-cardiovascular true positive (TP) cases, exposed to high PM2.5, and true negative (TN) controls, not exposed to elevated PM2.5, was evaluated in 72 Community Multiscale Air Quality (CMAQ) grids with (urban) and without (rural) air monitors. The odds ratio (OR) algorithm and the newly developed beta (ẞ) algorithm were used to evaluate the reliability and validity of TP cases, and TN controls in grids with and without air monitors. Four experimental AOD-PM2.5 fused surfaces and four health outcomes were evaluated. Only the linear predictor (ẞ) algorithm reliably and correctly identified TP cases and TN controls, with probabilities ~1.00. The OR algorithm only identified TN controls, with probabilities ~1.00, and significantly overestimated the percentage of TP cases. Regression analyses demonstrated that the OR algorithm's accuracy could be improved if the number of cases for all health outcomes was increased 50.8% in all grids and 73.9% in grids without monitors. Since the number and percentage of TP cases and TN controls were similar in grids with and without air monitors, this outcome suggests that the AOD-PM2.5 and health outcome concentration-response function evaluated in grids with monitors also holds in grids without air monitors.

In Biological and Agricultural Engineering disciplines, these projects can involve tasks such as field data collection, laboratory experiments or fabrication of prototypes that require access to specific laboratories and equipment. In the Spring 2020, Universities across the US shut down to prevent the spread of COVID-19 and transitioned to remote or virtual courses. The objective of this study was to investigate the impact of the transition to remote and virtual courses on senior design or capstone courses in Biological and Agricultural Engineering to find lessons learned and help plan for future disruption in these courses. Four Senior Design Capstone Course instructors from different Biological and Agricultural Engineering departments were interviewed to gather their perspectives and experiences regarding changes in instruction;student projects' management and outcomes;as well as students' learning and performance in the course. The shift to remote learning triggered frustration on both students and instructors' sides. They also faced unprecedented challenges with technology and access. Instructors acknowledged student resilience and adaptability to the situation. The creative flexibility that instructors applied to course delivery, project deliverables and assessment is a key tool that allowed them to maintain the real-world experiential nature of BAE capstone programs. © American Society for Engineering Education, 2021}, booktitle={(c) American Society for Engineering Education, 2021}, author={Guertault, Lucie and Jones, Tamecia and Hall, Eric and Kolar, Praveen}, year={2021}, month={Jul} }

These response indicators belatedly address water quality issues, if the cause is impaired riparian functions. Riparian functions assist in decreasing the impacts of droughts and floods (through sequestration of nutrients and excess sediment), allow water to remain on the land surface, improve aquatic habitats, improve water quality, and provide a focus for monitoring and adaptive management. To manage water quality, the focus must be on the drivers (leading indicators) of the causative mechanisms, such as loss of ecological functions. Success in NPS pollution control, and maintaining healthy aquatic habitats, often depends on land management/land use approaches, which facilitate the natural recovery of stream and wetland riparian functions. Focusing on the drivers of ecosystem functions (e.g., vegetation, hydrology, soil, and landform), instead of individual mandated response indicators, using the proper functioning condition (PFC) approach, as a best management practice (BMP), in conjunction with other tools and management strategies, can lead to pro-active policies and approaches, which support positive change in an ecosystem or watershed, and in water quality improvement.}, number={6}, journal={Water}, publisher={MDPI AG}, author={Hall, Eric and Hall, Robert K. and Aron, Joan L. and Swanson, Sherman and Philbin, Michael J. and Schafer, Robin J. and Jones-Lepp, Tammy and Heggem, Daniel T. and Lin, John and Wilson, Eric and et al.}, year={2019}, month={May}, pages={1125} }

There are a few things to note in that respect. The Tui Chub is a bait fish. It is a lower-order prey fish for higher-order trout/salmonid species. Tui Chub is zooplanktivorous. Since the Tui Chub feed on zooplankton, if they themselves are prey for other species (or are being “culled” by artificial means), and there is no other entity to feed on the plankton and algae, the result would be a mass of plankton/algae bloom (i.e., harmful algal blooms (HABs)). This would lead to anoxic conditions in the euphotic zone, which puts even more stress on the higher-order trout/salmonid species.

The general approach for research designed to analyze health impacts of exposure to PM2.5 is to use concentration data from the nearest ground-based air quality monitor(s), which typically have missing data on the temporal and spatial scales due to filter sampling schedules and monitor placement, respectively. To circumvent these data gaps, this research project uses a Hierarchical Bayesian Model (HBM) to generate estimates of PM2.5 in areas with and without air quality monitors by combining PM2.5 concentrations measured by monitors, PM2.5 concentration estimates derived from satellite aerosol optical depth (AOD) data, and Community-Multiscale Air Quality (CMAQ) model predictions of PM2.5 concentrations. This methodology represents a substantial step forward in the approach for developing representative PM2.5 concentration datasets to correlate with inpatient hospitalizations and emergency room visits data for asthma and inpatient hospitalizations for myocardial infarction (MI) and heart failure (HF) using case-crossover analysis. There were two key objective of this current study. First was to show that the inputs to the HBM could be expanded to include AOD data in addition to data from PM2.5 monitors and predictions from CMAQ. The second objective was to determine if inclusion of AOD surfaces in HBM model algorithms results in PM2.5 air pollutant concentration surfaces which more accurately predict hospital admittance and emergency room visits for MI, asthma, and HF. This study focuses on the New York City, NY metropolitan and surrounding areas during the 2004-2006 time period, in order to compare the health outcome impacts with those from previous studies and focus on any benefits derived from the changes in the HBM model surfaces. Consistent with previous studies, the results show high PM2.5 exposure is associated with increased risk of asthma, myocardial infarction and heart failure. The estimates derived from concentration surfaces that incorporate AOD had a similar model fit and estimate of risk as compared to those derived from combining monitor and CMAQ data alone. Thus, this study demonstrates that estimates of PM2.5 concentrations from satellite data can be used to supplement PM2.5 monitor data in the estimates of risk associated with three common health outcomes. Results from this study were inconclusive regarding the potential benefits derived from adding AOD data to the HBM, as the addition of the satellite data did not significantly increase model performance. However, this study was limited to one metropolitan area over a short two-year time period. The use of next-generation, high temporal and spatial resolution satellite AOD data from geostationary and polar-orbiting satellites is expected to improve predictions in epidemiological studies in areas with fewer pollutant monitors or over wider geographic areas.}, journal={Environmental Research}, publisher={Elsevier BV}, author={Weber, Stephanie A. and Insaf, Tabassum Z. and Hall, Eric S. and Talbot, Thomas O. and Huff, Amy K.}, year={2016}, month={Nov}, pages={399–409} }

The optical remote sensing (ORS) area source measurement method EPA OTM 10 was used to provide Hg0 flux data for the site. These results are reported and compared with cell room roof-vent monitoring data acquired by the facility for similar time periods. The 24-h extrapolated mercury emission rate estimates determined by the two monitoring approaches are shown to be similar with overall averages in the 400 g day−1 range with maximum values around 1200 g day−1. Results from the OTM 10 measurements, which include both cell room emissions and potential fugitive sources outside the cell room, are shown to be approximately 10% higher than cell room monitoring results indicating that fugitive emissions from outside the cell room produce a small but measurable effect for this site.}, journal={Atmospheric Environment}, year={2009}, month={Jan} }
