Ultra-low velocity zones (ULVZs) are localized small-scale patches with extreme physical properties at the core-mantle boundary that often gather at the margins of Large Low Velocity Provinces (LLVPs). Recent studies have discovered several mega-sized UL
In a rigid diaphragm, the intraocular deformation equals zero; that is, the infiltration of the inside of the diaphragm is infinite and the movement of all nodes inside the class is dependent on the master joint. That is, with the displacement of the center of the diaphragm mass, the displa...
Extended joint spacing on flat slab concrete with PREVent-C means less joint maintenance would be needed over the life of the facility, resulting in decreased downtime, costs, and curling potential.
This model and 3D relocated hypocentres were used as input for a joint inversion. The inversion grid (Supplementary Fig. 1) was designed in spherical coordinates, encompassing all local earthquakes and guided by the station spacing in the more densely covered regions and increased spacing in the ...
All the slabs contained stud shear reinforcement (SSR) except a control slab where no SSR was provided. The test variables were the column size and the ratio of stud spacing to slab thickness. The punching shear strengths, load–deflection responses, and crack patterns predicted by the LFEM ...
The pavement performance is related to the structure size, thickness, joint treatment method, base treatment quality, and prefabricated board leveling technology. The effect of the application depends mainly on its economic benefit. Its typical application is shown in Fig. 2(b). View article ...
(0.05–0.5 Hz, 0.15–1.0 Hz, 0.25–1.5 Hz, 0.35–2.0 Hz) and employ the CRF technique to conduct a joint analysis of the broadband and short-period data (see Methods; Supplementary Figs.4–6). The denser spatial coverage of the short-period array allows us to better...

The joint is accessible, but I fear causing more damage trying to remove the fitting. Our HVAC repairman who maintains the boiler said that this leak is an indicator that the system is failing and should be replaced. He didn’t attempt any repairs for fear of opening a can of worms. ...
A device for forming, reinforcing, joint sealing and edge protecting of a concrete slab panel, wherein the concrete slab panel having a volume, a length, a width, and a surface. The
