Aldehydes are common air pollutants with carcinogenicity. Genotoxicity of single aldehyde has been studied well, but the combined genotoxicity is rarely known. Here, we evaluated formaldehyde and acrolein on BEAS-2B cells in terms DNA strands breakage, chromosome damage gene mutation below subcytotoxic concentrations covering smoking-related concentrations. Meanwhile, molecular mechanism was investigated further based oxidative stress, DNA-protein crosslinks (DPCs), cell cycle damage-repair...
The presence of symmetric and asymmetric voids directly affects the mechanical behaviors tunnel linings further induces diseases among influence factors. In this paper, 1:5-scale model tests were carried out to study reinforced concrete (RC) considering located at crown spandrel. Based on experimental results plastic damage (CDP) model, effects void (i.e., location size), subgrade stiffness, lining size bearing capacity RC investigated using numerical simulation. test parametric analysis...
Sodium alginate was modified for water resistance with acrylonitrile <italic>via</italic> by free radical graft copolymerization.
In this paper, 25‐ton and 27‐ton axle heavy trucks are used to carry out moving loading dynamic real vehicle test on the cracked section, intact repaired section of a railway tunnel foundation performance basement structure with change loads health conditions. By analyzing influence law response fatigue life haul train under different conditions (intact, damaged, repaired), adaptability equipment freight load is clarified. The results show that (1) can meet normal operation trains in good...
Loess slope broadly distributes in Northwest China, making the of area developed. And with development number construction projects still on rise, this is a high-intensity region multiple earthquakes, resulting landslide under earthquakes which very serious problem. However, study loess dynamic response yet rarely involved exploration influence shapes, leaves hidden danger to safety local engineering. In paper, typical ladder-type engineering selected as research object, and numerical...
The presence of voids or lining thinning directly affects the mechanical behavior linings, and these defects threaten safety tunnel operation. In this study, a series 1/5‐scale model tests was used to investigate normal concrete (NC) linings in consideration combined defects. Test results showed that void substantially reduced load‐bearing capacity deformation properties linings. inelastic also significantly affected by effects located at spandrel were slightly weaker than those crown. As...
This paper proposed a Coupled Eulerian-Lagrangian (CEL) finite element model to estimate the undrained piezocone resistance and penetration pore pressure in modified Cam clay (MCC). The numerical is verified through comparison with series of miniature test calibration chamber. value cone tip (qc), excess at face (u1) shoulder (u2) obtained from CEL are also compared analytic closed-form solution cavity expansion. Consequently, qc underpredicted by expansion approach, but predicted for...
The submersible buoy system is an important tool in the profile observation of marine environment. According to lumped mass based method, dynamic modeling established, then analysis carried out. model solved and analyzed by using software MATLAB. result provides theoretical reference for its structural design numerical computation system.
The mechanical properties of the lining are directly affected by defects such as voids behind and insufficient thickness lining. In order to quantitatively evaluate this effect, behavior under influence void lining, combination two kinds adopted 1/5 scale model test. Based on experimental research, numerical calculation models based CDP for defect established, with effects load direction, stratum stiffness, location, type, degree analyzed simulation. results show that weakens stiffness As...
T-A cloning is the most commonly used molecular technique in which T-vector core tool. T-vectors now are blue-white positive-selection vectors based on mechanism of alpha-complement beta-galactose Escherichia coli. Disadvantages these traditional application include insufficient positive rate and existence false-positive clones, which, especially latter, makes screening transformant clones via colony PCR necessary. In present study, a novel T-vector, strategy inhibiting growth negative...
Testing the health of tunnels, as a branch highway operation, has an extremely important application in public property and even life safety. Among them, there are many factors that cause tunnel to deform or collapse. The conventional methods use finite element method (FEM) which simulate bearing capacity loss rate lining by using mechanical method. However, it takes long time calculate stress-strain-situation model under each condition. This paper explores machine learning more conditions...
Municipal solid waste disposal and its sustainable management in China have undergone significant evolution since 2000. However, has a vast land area socioeconomic geographical disparities across the country, strategy of on national scale needs to be further evaluated. This study quantified effect social, economic, geographic drivers landfill/incineration activities 31 provinces from 2003 2020 by establishing an integrated TWFE-PRF-SDM methodology. The results showed, past two decades,...
Abstract The fatigue reliability of structural elements with penetration cracks under stress loading is analysed using the Kriging model. model established “FEM + M integral” intensity factor modelling method, and numerical determined by comparing theoretical simulated values factor. A kriging probability established, cracked structure obtained based on mean point method Monte Carlo method. influence law statistical characteristics random parameters crack containment specimens investigated....
