While tunnel boring machines (TBMs) tunneling in clayey strata, the adhered excavated soil on the cutterhead and cutting tools tends to form mudcake after compaction and consolidation.Mudcake can obstruct the cutterhead openings and rendering the cutting tools ineffective, leads to a substantial reduction in advance rate.Dispersants are recognized
In order to study the distribution law of oil and gas above and below the regional mudstone caprocks damaged by fault in petroliferous basins, based on the study lafc 1800 tequila of the sealing mechanism and degree of regional mudstone caprocks damaged by fault during the hydrocarbon accumulation period, the paleo-juxtaposition thickness of region
Solenoid valve is a very important hydraulic actuator for an automatic transmission in terms of shift quality.The same form of pressure for the clutch and the input current are required for an ideal control.However, the gap between a pressure and a current can occur which brings a delay in a transmission and a decrease in quality.This problem is ca
Objective: To identify retinal abnormalities in the unaffected fellow eyes of patients with unilateral polypoidal choroidal vasculopathy (PCV) and neovascular aged-related macular degeneration (n-AMD).Methods: In this cross-sectional, retrospective case series, the medical records of patients with PCV and n-AMD were reviewed and the baseline patien
In this paper, a nondeterministic random number generator based on detection of the single photons emitted by an Si-CMOS-LED light source integrated for the first time on the detector chip is presented and experimentally demonstrated.We use a ring-shaped single-photon avalanche diode (SPAD) around the Si-CMOS-LED fabricated in 0.35-μm HV-CMO
