Complex Associations between Environmental Factors and Child Growth: Novel Mixed-Methods Approach
(American Society of Civil Engineers, 2019)Environmental risks associated with child growth are complex, and intervention effectiveness has been consistently poor. To improve effectiveness, proper intervention points inside the complex system must be identified. ... -
Human Adenovirus 40 Removal in Sidestream Membrane Bioreactor
(American Society of Civil Engineers, 2019)This preliminary study investigates how the removal of human adenovirus in a membrane bioreactor (MBR) depends on the MBR configuration. Results from a sidestream MBR (ssMBR) are compared with data from an immersed MBR ... -
Sustainable Configuration of Bioretention Systems for Nutrient Management through Life-Cycle Assessment and Cost Analysis
(American Society of Civil Engineers, 2019)The need for stormwater quality control, especially the control of nutrients, has been recognized due to the widespread problem of water eutrophication. The bioretention system, as a green infrastructure, can remove the ... -
Biofilms in RBC with Constant Ages and Thicknesses
(American Society of Civil Engineers, 2019)With the exception of some strict kinetic formalism, biofilm thickness constitutes a basic parameter for analyzing the mechanisms of mass transfer as a result of microbiological growth. A research gap exists, however, ... -
