An empirical, energy-based methodology for liquefaction hazard assessment and microzonation mapping is presented. The approach is probabilistic, considers the uncertainty in the liquefaction criterion, and is applicable to most earthquake-induced liquefaction analyses. The examples illustrated are for water-saturated sands at level ground. The energy of ground shaking is estimated from the Four...

A predictive framework for flow liquefaction instabilities in sands is presented. A general criterion for liquefaction, based purely on the laws of physics, is presented and adapted to the important case of radial loading (e.g. triaxial, simple shear) using the Cambridge p9–q plane. Three important contributions are made in the paper. First, the instability concept is unified, and it is shown t...

AIM The most recent and innovative AquaLase liquefaction technology has offered an alternative to lens extraction. Many studies have investigated its functions and advantages. This article focuses on evaluating the in vivo microscopic cornea changes after AquaLase liquefaction by using a laser confocal microscope. METHODS In this perspective, randomized case study, 37 eyes of 35 patients subm...

Hydrogen energy is a crucial carrier for the growth of system and its low-carbon transformation. Using natural gas as hydrogen transport pipeline network transportation significant step toward realizing large-scale long-distance transport. Hydrogen-mixed mainly separated into by physical methods at present. High purity recovery, but recovery rate low. At same time, compared with gas, liquefied ...

This paper took hydrogen transportation as a breakthrough to make comprehensive study on the economic assessments of delivery pathways, so promote low-cost and large-scale energy development. A specific model for gas-hydrogen trailers, liquid-hydrogen tank trucks, pipelines with various technical levels was developed explore cost reduction pathways. To verify feasibility model, case conducted i...

Hydrogen is emerging as one of the most promising energy carriers for a decarbonised global system.
