Delivering Energy Savings For The Supply Chain Through Building Information Modelling As A Result Of The Horizon 2020 Energy Bimcert Project, Barry Mcauley, Avril Behan

Conference papers

The global buildings sector is now responsible for 40% of final energy consumption as well as accounting for 33% of energy-related carbon dioxide emissions. This has resulted in a growing urgency to address energy and emissions from buildings and construction, to meet restrictive 2020 targets as specified by the European Union (EU). To achieve these targets a number of funding initiatives have been put in place through Horizon 2020 with a focus on BIM, due to it having the potential to rapidly produce energy outputs that enable design teams to analyse and compare the most cost-effective, energy-efficient options. However, despite …

Learning From Incidents To Reduce The Risk Of Drowning In Swimming Pools: Implementation Of Experience-Based Feedback Regarding Near-Misses In Four Public Facilities In France, Élie Vignac, Pascal Lebihain, Bastien Soulé

International Journal of Aquatic Research and Education

The prevention of sports accidents must rely on a detailed knowledge of accident circumstances and risk factors. Today, very few studies have investigated in depth non-fatal drowning incidents that have occurred in public swimming pools (PSP). Learning from incidents seems likely to advance the knowledge of accident scenarios. This research study aimed to capture minor incidents that might identify safety lessons and preventive measures. Incidents of minor and major aquatic events were collected from four PSPs that had hosted 700,000 bathers per year. About 800 incidents and 300 aquatic rescues performed by lifeguards were recorded within a time frame of …

Integrating Humanities Into Environmental Engineering Classrooms, Sarah Bauer

Open Educational Resources

In this module, students will be exposed to the broader context of several major components within the area of environmental engineering by integrating humanities into the environmental engineering classroom. This module includes lecture content pertaining to the areas of (1) solid and hazardous waste management and (2) management of air pollution. This module will help provide students with a background of these subject areas by: introducing students to the history of waste management practices and regulations in the United States and exposing students to various major air pollution episodes throughout history and the implications air pollution has on human and …

Historical Changes In Lower Columbia River And Estuary Floods: A Numerical Study, Lumas Helaire, Stefan Talke, David A. Jay, Andrew Mahedy

Civil and Environmental Engineering Faculty Publications and Presentations

Over the past 150 years, the Lower Columbia River Estuary controlling depth has approximately doubled, the majority of historical wetlands and floodplain have been reclaimed, numerous infrastructure projects have altered and confined flow pathways, and significant natural and anthropogenic changes to the discharge hydrograph have occurred. To investigate the effect of these changes on tides, river slope, and flood water levels, we construct and validate numerical models that simulate flow over late nineteenth‐century and present‐day bathymetry. The models are validated using archival (1853–1877) and modern tide measurements throughout the Lower Columbia River Estuary and river stage measurements from the tidal …

The Water/Energy Nexus: Climate, Consumption And Ecosystem Services, Hildegaard D. Link

Dissertations, Theses, and Capstone Projects

Water and energy are drivers of living systems. This work provides an assessment of the Water Energy Nexus in the United States, comparing the well-watered north-east and the arid west. Electric grid systems are most stressed on hot summer afternoons. Grid stress can lead to cascading failures of electricity, water and wastewater treatment systems. (Zimmerman, 2017) Water for power generation and/or water supply depend on ecosystem services. The ecosystem services and resource trade-offs embedded in provision of a watt of power and an ounce of potable water, however, have yet to be comprehensively enumerated nor have the cost relationships been …

Organic/Inorganic Interfacial Interactions Affecting Metal Reactivity: Water Treatment And Sensor Applications, Mohamed Nabil Shaikh

Civil Engineering ETDs

The aim of this dissertation was to investigate the interactions occurring at the organic – inorganic interface between solid media and aqueous contaminants for water treatment and sensor applications. The gaps in current literature on these interfacial organic-inorganic interactions must be bridged in order to develop advanced water treatment and monitoring technologies for improving water quality and thus, restore and protect the contaminated water resources. As a part of this dissertation, manganese oxides-based composites and electrospun polymer mats were developed and investigated for gaining mechanistic insights of organic (bisphenol A and acetaminophen) and inorganic (uranium) contaminants removal, respectively. These reactions …

Visualizing The Fate And Distribution Of Pahs In Spartina And Avicennia Tissues From Barataria Basin, La, Kristina Jeannette Sebastian

LSU Master's Theses

During crude oil spill events, vegetation in marsh environments sequester polycyclic aromatic hydrocarbons (PAHs) from the crude oil by partitioning from the air phase through the waxy cuticle on the leaf surface. Recent studies from Macondo oil-impacted marshes have demonstrated that cycling of low molecular weight petrogenic PAHs occurs through the cuticle and other leaf tissue. At present, our understanding of how PAHs travel through the cuticle is coarse and limited by grab samples across the entire leaf, which preventing a full understanding the dynamics of PAH cycling in this environment. Multiphoton (MP) confocal microscopy visualizes the distribution of PAHs …

Water Quality Analysis Of Ecoroof Runoff In Portland, Pranoti P. Deshmukh

Civil and Environmental Engineering Master's Project Reports

Portland, Oregon is internationally recognized for its implementation of sustainable stormwater management technologies. Ecoroof is one of the sustainable solutions to reduce stormwater runoff which also provides multiple environmental benefits. However, very little is known about the impact of ecoroofs on water quality of roof runoff. Stormwater runoff carries a significant amount of pollutants, which, if it directly enters a stream or river, degrades water quality and severely harms aquatic life.

This study evaluates the trends in the long-term water quality data from ecoroofs and conventional roofs in the Portland area. Mann Kendall trend test was used to detect the …

Role Of Submicrometer Particles In Advanced Technologies Of Carbon Capture, Zhichao Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

Oxy-combustion and post-combustion carbon capture technologies are two of the most promising strategies for carbon capture and storage (CCS), which is a commonly accepted approach to address the challenge of climate change. Pressurized oxy-combustion has been actively studied due to its great potential to enhance the power plant energy efficiency by recovering latent heat from water vapor condensation without incurring additional gas compression cost. On the other hand, amine-based CO2 scrubbers have been demonstrated to have high removal efficiency of CO2 with the possibility to recycle amine solutions, which makes the technology a promising candidate for post-combustion carbon capture. Nonetheless, …

Effects Of Nutrient Level And Growth Rate On Mutation And Conjugation Processes That Confer Antibiotic Resistance To E. Coli, Mohammadreza Shafieifini

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Antibiotic resistance genes (ARGs) may enter surface water with the discharge of treated wastewater. Conjugation is a main mechanism for the horizontal gene transfer of ARGs from wastewater microbiome to the microbiome indigenous to surface water. However, little is known about how environmental factors affect the conjugation process of ARGs.

In this thesis, an extensive research related to spreading antibiotic resistance genes in the environment is reported. The project investigated how environmental parameters may affect the rate of dissemination of ARGs and in what extent the resistance level of the population is changed after mutation and conjugation event. The chemostat …
