In the hydraulic model simulations of 16-h periods of 1 l h−1 ingress of untreated domestic sewage, the spread of the contamination through the network and the E. coli concentration dynamics were calculated.
Ten occultation experiments, including 10 ingress and 9 egress measurements, have been conducted by February 2017.
The first observation was conducted on March 3, 2016, and 10 occultation experiments, including 10 ingress (entry) and 9 egress (exit) measurements, have been conducted by April 2017.
Gaseous O2 ingress into the covered waste rock was more sensitive to the channel location than to the saturated hydraulic conductivity of the material filling the channel.
An ideal engineered soil cover can mitigate acid rock drainage (ARD) by limiting water and gaseous O2 ingress into an underlying waste rock pile.
It is therefore of interest to investigate the physical and geochemical processes, including naturally-occurring redox reactions, that may control O2 ingress.
The applicability of the numerical simulation method to a micro-channel type heat exchanger, e.g. PCHE, was assessed qualitatively, and the possibility of a self-plugging or self-mitigation against the CO2 ingress accident was discussed as well.
A numerical simulation method for the potential tube rupture and the consequential CO2 ingress accident possibly occurring inside the Na CO2 heat exchanger of a SFR employing a supercritical CO2 Brayton cycle has been developed.
Upon oxidation in 0.5 M LiClO4/acetonitrile, a mass change of 43 g/mol is observed for PANI MoS3 and this suggests that solvent is also involved in addition to ClO4− ingress and Li+ expulsion.
For the parameter ranges investigated, results indicate that for the single fracture case, the most influential factors controlling dissolved O2 ingress are flow velocity in the fracture, fracture aperture, and the biotite reaction rate in the rock matrix.
This monster has up to three wireless systems including WWAN, built-in GPS, and "meets MIL STD 810F (military standard) ratings for drop/shock and vibration and the IP54 (ingress protection)," which I suspect means it's hard to break unless the military does something with their laptops that I'm not aware of.
