RISElastohydrodynamic Lubrication Model With Limiting Shear Stress Behavior Considering Realistic Shear Thinning and Piezo Viscous Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses a largely ignored aspect pertaining to the elastohydrodynamic lubrication (EHL) traction behavior of fragile lubricants which undergo transition to glassy state at typical EHL contact zone pressures. ...
Removing Selenium(IV) and Arsenic(V) Oxyanions with Tailored Chelating Polymers
Publisher: American Society of Civil Engineers
Abstract: The need for selective sorption of trace concentrations of toxic Se(IV) and As(V) oxyanions, especially in the presence of competing high concentrations of sulfate ions, is well recognized. In this regard, previous ...
Out of Sync: World Bank Funding for Housing Recovery, Postdisaster Planning, and Participation
Publisher: American Society of Civil Engineers
Abstract: The World Bank is increasingly at the forefront of housing reconstruction in countries affected by disasters. Yet, the literature on the World Bank’s postdisaster housing projects is rather thin. This paper examines the ...
Effects of Cocontamination by Toluene on Cr(VI) Adsorption by P-nZVI in a Soil–Water System: A Fixed-Bed Column Study
Publisher: ASCE
Abstract: Soil–water cocontamination with heavy metals and nonaqueous phase liquids (NAPLs) raises widespread concerns. Coexisting NAPL pollutants like toluene can antagonize the chemical processes employed for removing target heavy ...
Homogenization of Daily Temperature Data
Publisher: American Meteorological Society
Abstract: AbstractThis paper develops a method for homogenizing daily temperature series. While daily temperatures are statistically more complex than annual or monthly temperatures, techniques and computational methods have been ...
Unsteady Vortex Flows Produced by Trailing Edge Articulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady vortex flows produced by biologically inspired tail articulation are investigated. The application is to provide active means of reducing tonal noise due to upstream wake interaction ...
Mass Balance and Water Quality Modeling for Load Allocation of <i>Escherichia coli</i> in an Urban Watershed
Publisher: American Society of Civil Engineers
Abstract: A modeling approach based on mass balance coupled with the Hydrologic Simulation Program in FORTRAN (HSPF) is developed in this study to evaluate bacteria reduction strategies and their impact on water quality for an urban ...
Impact of Nonaqueous Phase Liquid on Cr(VI) Removal by Nano Zerovalent Iron Particles: Effects of Contact Time, Pollution Load, and pH
Publisher: American Society of Civil Engineers
Abstract: Nanoscale zerovalent iron (nZVI) was synthesized and employed for treating chromium(VI) containing aqueous solution through adsorption using a series of microcosm experiments. The experiments were then performed to study ...
Biomonitoring and Phytoremediation of Cr (VI) Contaminated Water: Study on Bioaccumulation and Morphological Responses in <i>Eichhornia crassipes</i>
Publisher: ASCE
Abstract: This study examined the potential of the aquatic macrophyte Eichhornia crassipes for bioaccumulating hexavalent chromium and its effects on the plant’s morphology. The macrophytes were exposed to different concentrations ...
