The power of ionic movements in plants
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Development and construction technology of high pre-tightening force stress uniform anchor cable
As one of the key parameters of roadway support, preload plays a decisive role in active support, and studies at home and abroad have shown that improving preload can effectively control roadway deformation and reduce the occurrence of roofing accidents.

Analysis on Application Effect of Prestressed Anchor Cable in Large Span Tunnel
Abstract Safety is the top priority during the construction process, the construction risk increases sharply with the increase of section size. Bifurcated tunnel structure is adopted in the entrance portal section of Bibanpo tunnel. The span of transition section reaches 25.79m (type A) and 22.11mm (type B), To ensure safety, a new ...

Controlling deformation is of paramount importance during deep excavation in urban core areas, particularly deep excavation adjacent to high‐rise structures. This study proposes three support schemes; retaining piles + internal bracing (RPIB, Scheme A), double‐row piles (DRP, Scheme B), and pile‐anchor system (PAS, Scheme C) on a deep excavation near a

Experimental study on internal monitoring structure of a new prestressed anchor cable
On account of their difficult internal stress monitoring, a new type of internal stress monitoring structure for pre-stressed anchor cables is developed and then tested by the destructive tension tests and the repeated tension tests under multi-levelload.

This study utilizes synthetic ground motions to analyze the seismic response of superlong base‐isolated structures, with a focus on their multidimensional, spatially varying, and nonstationary characteristics under actual earthquake conditions. A classic power spectrum model combined with a trigonometric series method is adopted to generate spatially ...
