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, ... -
Seasonal Dynamics of the Airborne Bacterial Community and Selected Viruses in a Children's Daycare Center
(PLOS, 2016-03-04)Children’s daycare centers appear to be hubs of respiratory infectious disease transmission, yet there is only limited information about the airborne microbial communities that are present in daycare centers. We have ... -
Secondary organic aerosol formation from ambient air in an oxidation flow reactor in central Amazonia
(European Geophysical Union, 2018-01-17)Secondary organic aerosol (SOA) formation from ambient air was studied using an oxidation flow reactor (OFR) coupled to an aerosol mass spectrometer (AMS) during both the wet and dry seasons at the Observations and Modeling ... -
Sediment microbial fuel cells for wastewater treatment: challenges and opportunities
(The Royal Society of Chemistry, 2015-03-27)Sediment microbial fuel cells (SMFCs) have been intensively investigated for the harvest of energy from natural sediment, but studies of their application for wastewater treatment mainly occurred in the past 2-3 years. ... -
Sediment-Water Column Oxygen and Nutrient Fluxes in Nearshore Environments of the Lower Delmarva Peninsula, USA
(Inter-Research, 1995)Sediment-water column exchanges of oxygen, dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) were measured in situ over an annual cycle for sandy and silt-clay sediment types in a shallow Chesapeake ... -
Seismic behavior investigation of the steel multi-story moment frames with steel plate shear walls
(Techno Press, 2020-10)Steel plate shear walls are recently used as efficient seismic lateral resisting systems. These lateral resistant structures are implemented to provide more strength, stiffness and ductility in limited space areas. In this ... -
Self-Centering Seismic Lateral Force Resisting Systems: High Performance Structures for the City of Tomorrow
(MDPI, 2014-09-18)Structures designed in accordance with even the most modern buildings codes are expected to sustain damage during a severe earthquake; however; these structures are expected to protect the lives of the occupants. Damage ... -
Shape optimization of butterfly-shaped shear links using grey wolf algorithm
(2019-03)The shear loading applied to structures is resisted by implementation of hysteric dampers as structural seismic force resisting system. Recently, steel plates with engineered cut-outs are introduced to have controlled ... -
Shotgun Metagenomics Reveals Taxonomic and Functional Shifts in Hot Water Microbiome Due to Temperature Setting and Stagnation
(Frontiers, 2018-11-13)Hot water premise plumbing has emerged as a critical nexus of energy, water, and public health. The composition of hot water microbiomes is of special interest given daily human exposure to resident flora, especially ... -
Single-Cell Analysis Reveals that Chronic Silver Nanoparticle Exposure Induces Cell Division Defects in Human Epithelial Cells
(MDPI, 2019-06-11)Multiple organizations have urged a paradigm shift from traditional, whole animal, chemical safety testing to alternative methods. Although these forward-looking methods exist for risk assessment and predication, animal ... -
Sources and transformations of particle-bound polycyclic aromatic hydrocarbons in Mexico City
(Copernicus Publications, 2006-05-01)Understanding sources, concentrations, and transformations of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere is important because of their potent mutagenicity and carcinogenicity. The measurement of particle-bound ... -
Sources of airborne microorganisms in the built environment
(Biomed Central Ltd, 2015-12-22)Each day people are exposed to millions of bioaerosols, including whole microorganisms, which can have both beneficial and detrimental effects. The next chapter in understanding the airborne microbiome of the built environment ... -
Spatial and temporal variability of particulate polycyclic aromatic hydrocarbons in Mexico City
(Copernicus Publications, 2008)As part of the Megacities Initiative: Local and Global Research Observations (MILAGRO) study in the Mexico City Metropolitan Area in March 2006, we measured particulate polycyclic aromatic hydrocarbons (PAHs) and other ... -
Spatial distribution of imperviousness and the space-time variability of rainfall, runoff generation, and routing
(American Geophysical Union, 2010-07-01)We study the relationship between the spatial distribution of imperviousness and the space-time variability of rainfall, runoff generation, and hydrologic response. For this study we follow an analytical framework that is ... -
Stabilization of a Clayey Soil with Ladle Metallurgy Furnace Slag Fines
(MDPI, 2020-09-24)The research study described in this paper investigated the potential to use steel furnace slag (SFS) as a stabilizing additive for clayey soils. Even though SFS has limited applications in civil engineering infrastructure ... -
A Standard Characterization Methodology for Respirable Coal Mine Dust Using SEM-EDX
(MDPI, 2015-12-14)A key consideration for responsible development of mineral and energy resources is the well-being of workers. Respirable dust in mining environments represents a serious concern for occupational health. In particular, coal ... -
