Therefore, the CO2 absorption rates in aqueous ammonia solution with 0 and 0.1 CO2 loading were investigated with a wetted wall column in this study.
On-site simultaneous removal of As and Sb from mining wastewater was achieved by using a reusable granular TiO2 column in this study.
The truss-arch model method is employed to calculate the fully diagonally cracked shear stiffness of a RECC column in this study.
Although use of the EndoTrap column in this study slightly reduced CRA concentrations, through appropriate dilution, we were able to maintain the same total amount of 61.9 ng CRA for all treatments (Table 2).
In addition to determining degradation kinetics of TCE in the presence of nitrate, the columns used in this study were equipped with electrodes which allowed for in situ measurements of corrosion potentials of the iron material.
Note that, for reinforced concrete columns examined in this study, P o was computed from 0.8[ 0.85 f c ′ )(A g − A rs ) + f y A rs ], as permitted by ACI 318-11 (2011), where f c ′, f y = specified compressive and yield strengths of concrete and reinforcing steel, and A g, A rs = areas of the gross concrete cross section and of the longitudinal reinforcing steel.
Specifications of SEC columns used in this study.
All the columns used in this study were washed and reconditioned after every 50 injections.
The AEX columns used in this study were 0.5 cm in diameter and either 5 or 15 cm in height, and were operated in weak partitioning mode (Iskra et al., 13; Kelley et al., 18).
When fractured longitudinal bars (and critical section) are located near the base of the column, as was the case for Column 1 in this study, a large force demand is required of the CFRP strengthening system, as well as a substantial anchorage system to develop it.
