Energy Budget of Intermediate-Depth Earthquakes in Northern Chile: Comparison With Shallow Earthquakes and Implications of Rupture Velocity Models Used
(Blackwell Publishing Ltd, 2019)
We calculate well-resolved corner frequencies and radiated energies for a set of 96 earthquakes divided into two clusters located in the same tectonic setting but with different depths in northern Chile. Fifty-three shallow ...
Biomechanical failure properties and microstructural content of ruptured and unruptured abdominal aortic aneurysms
(ELSEVIER SCI LTD, 2011)
Purpose: To test the hypothesis that ruptured abdominal aortic aneurysms (AAA) are globally weaker than unruptured ones. Methods: Four ruptured and seven unruptured AAA specimens were harvested whole from fresh cadavers ...
Determining Significant Morphological and Hemodynamic Parameters to Assess the Rupture Risk of Cerebral Aneurysms
(Springer Berlin Heidelberg, 2019)
Hemodynamics and morphology are recognized as major factors in the rupture risk of cerebral aneurysms, and exploration of their relationship is necessary to establish a method that can be employed by clinicians to assess ...
Earthquake dynamics on circular faults: a review 1970–2015
(Springer, 2016)
We review the development of earthquake dynamics taken from the point of view of the origin of seismic radiation instead of the detailed study of rupture propagation on complex surfaces. Many features of seismic radiation ...
Effects of hypertension and pressure gradient in a human cerebral aneurysm using fluid structure interaction simulations
(World Scientific, 2017)
Fluid-structure interaction (FSI) simulations were carried out in a human cerebral aneurysm model with the objective of quantifying the effects of hypertension and pressure gradient on the behavior of fluid and solid ...
Effect of Wood Moisture Content in Edge Glued Panel Bonding for Furniture Industry: Analysis of Shear-Stress and Rupture in Bondline
(2014-01-01)
The objective of this article was to study the influence of the Pinus taeda wood moisture content to the production of EGP (Edge Glued Panel) in the bonding stage, using PVA adhesive. It was analyzed the joint resistances ...
Global rupture parameters for deep and intermediate-depth earthquakes
We investigate the global rupture parameters for deep and intermediate-depth earthquakes. From measurements of rupture duration and radiated seismic energy we estimate stress drop, apparent stress, and radiation efficiency ...
Heterogeneous self-arrested ruptures leading to spatial variability of radiated energy and Doppler effect of the observed corner frequency
(2023)
The study of the strong ground motion is of utmost relevance because the amplitude of seismic waves and their frequency content could severely damage structures. As both the amplitude and the frequency content directly ...
Expression of 8-oxoguanine Glycosylase in Human Fetal Membranes
(Wiley-Blackwell, 2014-07-01)
Problem The most common DNA lesion generated by oxidative stress (OS) is 7, 8-dihydro-8-oxoguanine (8-oxoG) whose excision repair is performed by 8-oxoguanine glycosylase (OGG1). We investigated OGG1 expression changes in ...
