RISBiological Nutrient Removal in Municipal Wastewater Treatment: New Directions in Sustainability
Publisher: American Society of Civil Engineers
Abstract: To control eutrophication in receiving water bodies, biological nutrient removal (BNR) of nitrogen and phosphorus has been widely used in wastewater treatment practice, both for the upgrade of existing wastewater treatment ...
The Design of an Ambient Neutron Dose-Equivalent Meter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: At present, most of the developed neutron dosimeters used to measure the neutron ambient dose-equivalent that has a moderator with a single counter, applied in neutron radiation fields within ...
Exploring Cementitious Additives for Pretreatment of High-Early-Strength Sewage Sludge from the Perspective of the Rapid Generation of Nonevaporable Water
Publisher: American Society of Civil Engineers
Abstract: Currently, solidification/stabilization (S/S) is the most widely used pretreatment measure for sewage sludge prior to its disposal in landfills in China. Looking for an effective measure to increase the early strength of ...
Assessment and Optimization of Soil Mixing and Umbrella Vault Applied to a Cross-Passage Excavation in Soft Soils
Publisher: American Society of Civil Engineers
Abstract: Focusing on three-dimensional finite-element analysis (FEA) for the assessment and optimization of reinforcement treatment using deep soil-mixing and umbrella vault methods to stabilize a cross-passage excavation in soft ...
Simultaneous Desulfurization and Denitrification by Microwave Catalytic over FeCoCu/Zeolite 5A Catalyst
Publisher: American Society of Civil Engineers
Abstract: FeCoCu/zeolite 5A was used as a catalyst for microwave catalytic desulfurization and denitrification and for microwave catalytic reduction of
An Improved QC Process for Temperature in the Daily Cooperative Weather Observations
Publisher: American Meteorological Society
Abstract: TempVal is a spatial component of data quality assurance algorithms applied by the National Climatic Data Center (NCDC), and it has been used operationally for about 4 yr. A spatial regression test (SRT) approach was ...
Numerical Simulation of High-Strength Concrete Creep under Cyclic Load
Publisher: ASCE
Abstract: To study the development of high-strength concrete creep under cyclic load as well as the distribution of moisture flow velocity, pore pressure, and equivalent stress, a concrete creep model based on a porous medium was ...
Removal of Hexachlorobenzene from Kaolin by Electrokinetics Coupled with Cu/Fe PRB
Publisher: American Society of Civil Engineers
Abstract: This study deals with the remediation of clayed soils contaminated with hydrophobic organic compounds (HOCs) by using electrokinetics (EK) coupled with a permeable reactive barrier (PRB) technique. Hexachlorobenzene (HCB) ...
Effect of Nano-Kaolinite Clay on Rebar Corrosion and Bond Behavior Between Rebar and Concrete
Publisher: ASCE
Abstract: The effect of nano-kaolinite clay (NKC) on the bond behavior between rebar and concrete was studied in a series of experiments. An electrical corrosion method was used to corrode the rebar embedded in concrete specimens. ...
Minimum Distance Calculation Method for Collision Issues in Lifting Construction Scenarios
Publisher: American Society of Civil Engineers
Abstract: In the construction process of prefabricated buildings, collision detection of the tower crane’s lifting path is of paramount importance. During the actual operation of a tower crane, attention is not only given to whether ...
