Metabolism And Photolysis Of 2,4-Dinitroanisole In Arabidopsis, Hunter W. Schroer, Xueshu Li, Hans Joachim Lehmler, Craig L. Just

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

New insensitive munitions explosives, including 2,4-dinitroanisole (DNAN), are replacing traditional explosive compounds to protect soldiers and simplify transport logistics. Despite the occupational safety benefits of these new explosives, feasible strategies for cleaning up DNAN from soil and water have not been developed. Here, we evaluate the metabolism of DNAN by the model plant Arabidopsis to determine whether phytoremediation can be used to clean up contaminated sites. Furthermore, we evaluate the role of photodegradation of DNAN and its plant metabolites within Arabidopsis leaves to determine the potential impact of photolysis on the phytoremediation of contaminants. When exposed to DNAN for three …

Rheological Properties Considering The Effect Of Aggregates On Concrete Slump Flow, Tae Yong Shin, Jae Hong Kim, Seong Ho Han Dec 2017

Rheological Properties Considering The Effect Of Aggregates On Concrete Slump Flow, Tae Yong Shin, Jae Hong Kim, Seong Ho Han

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Rheology of concrete allows us to understand the flow behavior of concrete and further extend the quantitative evaluation of its construction performance. The use of a concrete rheometer is promising for the purpose but sometimes limited high associated cost and procedure complexity. This study proposes a simulation-based model that correlates the slump flow test results to a concrete's rheological properties, allowing quantitative evaluation through this simple method. The proposed model is based on single-fluid simulation using the volume-of-fluid method, with an extension to accommodate the partial segregation of coarse aggregates. Either the channel flow or the L-shaped panel filling of …

How We Compute N Matters To Estimates Of Mixing In Stratified Flows, Robert S. Arthur, Subhas K. Venayagamoorthy, Jeffrey R. Koseff, Oliver B. Fringer

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Most commonly used models for turbulent mixing in the ocean rely on a background stratification against which turbulence must work to stir the fluid. While this background stratification is typically well defined in idealized numerical models, it is more difficult to capture in observations. Here, a potential discrepancy in ocean mixing estimates due to the chosen calculation of the background stratification is explored using direct numerical simulation data of breaking internal waves on slopes. Two different methods for computing the buoyancy frequency, one based on a three-dimensionally sorted density field (often used in numerical models) and the other based on …

On The Propagation Of Gravity Currents Over And Through A Submerged Array Of Circular Cylinders, Jian Zhou, Claudia Cenedese, Tim Williams, Megan Ball, Subhas K. Venayagamoorthy, Roger I. Nokes

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The propagation of full-depth lock-exchange bottom gravity currents past a submerged array of circular cylinders is investigated using laboratory experiments and large eddy simulations. Firstly, to investigate the front velocity of gravity currents across the whole range of array density (i.e. the volume fraction of solids), the array is densified from a flatbed towards a solid slab under a particular submergence ratio, where is the flow depth and is the array height. The time-averaged front velocity in the slumping phase of the gravity current is found to first decrease and then increase with increasing. Next, a new geometrical framework consisting …

What Lessons Can Be Learned From The Delivery Of The First Building On The Grangegorman Campus Using Building Information Management (Bim)?, Pat O'Sullivan, Avril Behan

Conference papers

There is an acceptance that BIM, via data management, can be integrated with FM to reduce costs during the Operations and Maintenance stage of a project. However, what has not been documented is the ‘on the ground’ reality which can be reviewed as a lessons learnt exercise to improve the implementation of BIM FM for future projects. This case study sets out to explore the realities of a client’s adoption of BIM based upon the actual experience of the Greenway Hub. Rather than relying on anecdotal evidence the research was based upon the real practices and experiences of the Dublin …

Benzophenone-3 (also known as BP-3 or oxybenzone) is added to sunscreens, plastics, and some coatings to filter UV radiation. The suspected endocrine disruptor BP-3 has been detected in the air and settled dust of homes and is expected to redistribute from its original sources to other indoor compartments, including clothing. Given its physical and chemical properties, we hypothesized that dermal uptake from clothing could contribute to the body burden of this compound. First, cotton shirts were exposed to air at an elevated concentration of BP-3 for 32 days; the final air concentration was 4.4 μg/m3. Next, three participants wore the …

Impact Of Surface Ozone Interactions On Indoor Air Chemistry: A Modeling Study, M. Kruza, A. C. Lewis, G. C. Morrison, N. Carslaw

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

An INdoor air Detailed Chemical Model was developed to investigate the impact of ozone reactions with indoor surfaces (including occupants), on indoor air chemistry in simulated apartments subject to ambient air pollution. The results are consistent with experimental studies showing that approximately 80% of ozone indoors is lost through deposition to surfaces. The human body removes ozone most effectively from indoor air per square meter of surface, but the most significant surfaces for C6-C10 aldehyde formation are soft furniture and painted walls owing to their large internal surfaces. Mixing ratios of between 8 and 11 ppb of C6-C10 aldehydes are …
