Single‐cell Transcriptome Profiling Reveals Gene Regulatory Networks and Key Genes in the Root Epidermis and Cortical Cells Associated with Early Nodulation in Glycine Max

Advanced Science, EarlyView.
Single‐cell transcriptomics of soybean roots soon after rhizobial inoculation reveals epidermal and cortical cell‐specific programs and gene‐regulatory networks acting in symbiosis establishment. We identify an ethylene‐driven regulatory circuit involving WRKY6.3/6.4 transcription factors targeting select Nod19 genes that promotes infection‐thread ...

Reinforcement effects and mechanisms of vacuum preloading combined with alkaline residue treatment on dredging sludge

Yantu gongcheng xuebao
The vacuum preloading technology is widely used in the treatment of large-area silt foundations formed by dredging. In order to improve the traditional vacuum preloading reinforcement effects, a method of vacuum preloading combined with alkali residue ...

Preliminary study on real-time pore water pressure response and reinforcement mechanism of air-booster vacuum preloading treated dredged slurry

Rock and Soil Mechanics, 2020
Laboratory tests have been carried out for simulating dredged-slurry treatment combining air-booster and conventional vacuum preloading methods. Settlement plate, micro pore water pressure transducer and miniature vane shearing instrument are adopted for

Numerical Investigation to the Effect of Suction-Induced Seepage on the Settlement in the Underwater Vacuum Preloading with Prefabricated Vertical Drains

Journal of Marine Science and Engineering, 2021
Vacuum preloading combined with prefabricated vertical drains (PVDs) has the potential to improve the soft sediments under water, however, its development is partly limited by the unclear understanding of the mechanism.

Study and Analysis: Mechanism of Vacuum Preloading, Stress of Soil

, 2011
Several viewpoints of vacuum preloading mechanism were analyzed. Action process of vacuum preloading was compartmentalized three phases. They were seepage consolidation in shallow soil and “surcharge” effect in deep soil by vacuum suction, consolidation ...

Formation mechanism of clogging of dredge slurry under vacuum preloading visualized using digital image technology [PDF]

, 2021
Vacuum preloading combined with prefabricated vertical drains (PVDs) system has been widely used to improve the soft clay with high water content. Clogging is usually formed around the PVDs during the vacuum preloading, impeding the propagation of the ...

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Model Test of Using Vacuum Preloading to Improve Dredge

, 2011
Dredge materials with the water content more than 80% have been used for land reclamation in Tianjin, China. The dredge is transferred by pipeline to the reclamation place and then strengthened with the vacuum preloading technique. It has been found that

Ground improvement using vacuum preloading together with prefabricated vertical drains [PDF]

, 2010
The use of vacuum preloading as an alternative to or in combination with fill preloading has become widely acceptable throughout the world. A number of successful case histories of vacuum preloading using different techniques have been reported in the ...
