Spectral-element modeling of spontaneous earthquake rupture on rate and state faults: Effect of velocity-strengthening friction at shallow depths [PDF]

open access: yes, 2008
We develop a spectral-element methodology (SEM) for simulating dynamic rupture on rate and state faults and use it to study how the rupture is affected by a shallow fault region of steady-state velocity-strengthening friction.

Earthquake Environmental Effects of the 1992 MS7.3 Suusamyr Earthquake, Kyrgyzstan, and Their Implications for Paleo-Earthquake Studies

open access: yesGeosciences, 2019
Large pre-historical earthquakes leave traces in the geological and geomorphological record, such as primary and secondary surface ruptures and mass movements, which are the only means to estimate their magnitudes. These environmental earthquake effects (

Discussion on the latest surface ruptures near the Zhonggu village along the Selaha segment of the Xianshuihe fault zone

open access: yesDizhi lixue xuebao, 2022
The Selaha segment of the Xianshuihe fault zone was the seismogenic fault of the 2014 Kangding MS 6.3 earthquake. This segment has been considered as one of the most dangerous areas for surface rupture-induced earthquakes with a magnitude of M≥7 due to ...

Rupture of fetal vessels on placental surface [PDF]

open access: yesArchives of Disease in Childhood, 1971
Six placentae with subamniotic haematomata were studied and the lesions shown to be derived from ruptured varices of surface fetal veins. However, the changes in the vessel walls suggested that these fetal varices had been subjected to an increase of pressure for some time.

Surface characterization data for tethered polyacrylic acid layers synthesized on polysulfone surfaces. [PDF]

open access: yes, 2019
The data presented are supplementary to an article [Kim et al., 2019] on synthesis and surface characterization of tethered polyacrylic acid (PAA) layers on polysulfone (PSf) film/membrane surfaces via atmospheric pressure plasma-induced graft ...

Buried shallow fault slip from the South Napa earthquake revealed by near-field geodesy. [PDF]

open access: yes, 2017
Earthquake-related fault slip in the upper hundreds of meters of Earths surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture.

Mechanical compression to characterize the robustness of liquid marbles [PDF]

open access: yes, 2015
In this work, we have devised a new approach to measure the critical pressure that a liquid marble can withstand. A liquid marble is gradually squeezed under a mechanical compression applied by two parallel plates.

A two-stage ceramic tile grout sealing process using a high power diode laser Part II: Mechanical, chemical and physical properties [PDF]

open access: yes, 1998
Ceramic tiles sealed using a portable 60 W-cw high power diode laser (HPDL) and a specially developed grout material having an impermeable enamel surface glaze have been tested in order to determine the mechanical, chemical and physical characteristics ...

The enamelling of concrete for improved performance characteristics by means of high power diode laser interaction [PDF]

open access: yes, 2003
The contemporary 120 W high power diode laser (HPDL) has been successfully used for the first time to fire an enamel glaze onto the ordinary Portland cement (OPC) surface of concrete.
