Reducing water scarcity by improving water productivity in the United States
(2020-09)Nearly one-sixth of U.S. river basins are unable to consistently meet societal water demands while also providing sufficient water for the environment. Water scarcity is expected to intensify and spread as populations ... -
Relationship between Humidity and Influenza A Viability in Droplets and Implications for Influenza's Seasonality
(PLOS, 2012-10-03)Humidity has been associated with influenza’s seasonality, but the mechanisms underlying the relationship remain unclear. There is no consistent explanation for influenza’s transmission patterns that applies to both temperate ... -
Relationship between Organic Carbon and Opportunistic Pathogens in Simulated Glass Water Heaters
(MDPI, 2015-06-09)Controlling organic carbon levels in municipal water has been hypothesized to limit downstream growth of bacteria and opportunistic pathogens in premise plumbing (OPPPs). Here, the relationships between influent organic ... -
Relative Performance of 1-D Versus 3-D Hydrodynamic, Water-Quality Models for Predicting Water Temperature and Oxygen in a Shallow, Eutrophic, Managed Reservoir
(MDPI, 2021-01-03)Many researchers use one-dimensional (1-D) and three-dimensional (3-D) coupled hydrodynamic and water-quality models to simulate water quality dynamics, but direct comparison of their relative performance is rare. Such ... -
Remote collection of microorganisms at two depths in a freshwater lake using an unmanned surface vehicle (USV)
(PeerJ, 2018-01-26)Microorganisms are ubiquitous in freshwater aquatic environments, but little is known about their abundance, diversity, and transport. We designed and deployed a remote-operated water-sampling system onboard an unmanned ... -
Research Needs, Challenges, and Strategic Approaches for Natural Hazards and Disaster Reconnaissance
(2020-11-10)Natural hazards and disaster reconnaissance investigations have provided many lessons for the research and practice communities and have greatly improved our scientific understanding of extreme events. Yet, many challenges ... -
A Research on Low Modulus Distributed Fiber Optical Sensor for Pavement Material Strain Monitoring
(MDPI, 2017-10-19)The accumulated irreversible deformation in pavement under repeated vehicle loadings will cause fatigue failure of asphalt concrete. It is necessary to monitor the mechanical response of pavement under load by using sensors. ... -
Resistance to IT Change in the AEC Industry: An Individual Assessment Tool
(2008)Numerous IT adoption studies within the AEC industry identify issues with individuals resisting IT changes. Current change models often only look at organizations and tasks and frequently neglect the individuals involved. ... -
Respirometric activities of unacclimatized Enterobacter aerogenes and mixed culture bacteria in sequencing batch reactor systems in response to acrylamide and its biodegradation products
(The Royal Society of Chemistry, 2018-10-07)The acute effects of acrylamide and its biodegradation products on the respiration activities of microbes during wastewater treatment are not well understood. Herein, unacclimatized mixed culture bacteria and Enterobacter ... -
Reusing Treated Wastewater: Consideration of the Safety Aspects Associated with Antibiotic-Resistant Bacteria and Antibiotic Resistance Genes
(MDPI, 2018-02-27)As more countries engage in water reuse, either intended or de facto, there is an urgent need to more comprehensively evaluate resulting environmental and public health concerns. While antibiotic-resistant bacteria (ARB) ... -
A Review of Modeling Bioelectrochemical Systems: Engineering and Statistical Aspects
(MDPI, 2016-02-18)Bioelectrochemical systems (BES) are promising technologies to convert organic compounds in wastewater to electrical energy through a series of complex physical-chemical, biological and electrochemical processes. Representative ... -
A Review of the Influence of Steel Furnace Slag Type on the Properties of Cementitious Composites
(MDPI, 2020-11-19)The type of steel furnace slag (SFS), including electric arc furnace (EAF) slag, basic oxygen furnace (BOF) slag, ladle metallurgy furnace (LMF) slag, and argon oxygen decarburization (AOD) slag, can significantly affect ... -

Role of coexisting tetragonal regions in the rhombohedral phase of Na0.5Bi0.5TiO3-xat.%BaTiO3 crystals on enhanced piezoelectric properties on approaching the morphotropic phase boundary
(AIP Publishing, 2012-01-01)The ferroelectric domain and local structures of Na0.5Bi0.5TiO3-xat.%BaTiO3 (NBT-x%BT) crystals for x = 0, 4.5, and 5.5 have been investigated by transmission electron microscopy. The results show that the size of polar ... -
The role of early design decisions on sustainability of mid-rise office buildings from a comparative LCA perspective
(2019)This study compares the environmental impacts of four professionally-designed archetypes building with different combinations of foundation, structure, and envelopes (FSE) assemblies. In addition, detailed operational ... -
Room temperature seed mediated growth of gold nanoparticles: mechanistic investigations and life cycle assesment
(The Royal Society of Chemistry, 2015-08-04)In this study, we report the first room temperature seed-mediated synthesis of gold nanoparticles (AuNPs) in the presence of citrate and a gold salt. In contrast to citrate-reduction in boiling water, these mild reaction ... -
Scavenging of Sub-Micron to Micron-Sized Microbial Aerosols during Simulated Rainfall
(MDPI, 2020-01-09)The processes removing aerosols from the atmosphere during rainfall are generically referred to as scavenging. Scavenging influences aerosol distributions in the atmosphere, with consequent effects on cloud properties, ...
