External pressure induced buckling collapse of high density polyethylene (HDPE) liners: FEM modeling and predictions
(Elsevier, 2015-08)
Abstract Thermoplastic polymers such as HDPE are nowadays widely used as lining materials for oil and gas pipelines. However, during maintenance or unexpected service stoppages, these liners can undergo external pressure ...
Numerical model of UOE steel pipes: Forming processand structural behavior
(ASOCIACIÓN ARGENTINA DE MECÁNICA COMPUTACIONAL AMCA, 2020)
A influência do esgoto doméstico como fluido de saturação no colapso de um solo arenoso
(Universidade Estadual Paulista (Unesp), 2003-05-26)
Analisa-se o comportamento colapsível de um solo arenoso inundado com esgoto doméstico. Em alguns casos, a contaminação do solo é provocada por vazamentos de produtos orgânicos e inorgânicos que ocorrem em reservatórios ...
Performance of tuned mass damper against structural collapse due to near fault earthquakes
(Elsevier, 2015-02)
Tuned mass dampers (TMD) are devices capable of reducing structural vibration by means of transferring energy from the protected structure to the control device. This vibration control strategy has relatively recent use ...
Gravity collapse structures in the Central Precordillera fold-and-thrust belt, Argentina
(Universidad Complutense de Madrid. Facultad de Ciencias Geológicas. Departamento de Estratigrafía, 2016-08)
Numerosas formas de relieve ubicadas en el área de la faja plegada y corrida de la Precordillera Central de Argentina, que a menudo se asocian con una tectónica compresiva, están de hecho relacionadas con procesos ...
Aspects of Mechanical Behavior and Modeling of a Tropical Unsaturated Soil
(2013-10-01)
The research studies the applicability of two elastoplastic models for the collapse prediction of the lateritic soil profile from Southeastern Brazil. These tropical soils have peculiar geotechnical behavior, due to their ...

Effect of Sleeping Position on Upper Airway Patency in Obstructive Sleep Apnea Is Determined by the Pharyngeal Structure Causing Collapse
(Oxford Univ Press Inc, 2017)
Objectives: In some patients, obstructive sleep apnea (OSA) can be resolved with improvement in pharyngeal patency by sleeping lateral rather than supine, possibly as gravitational effects on the tongue are relieved. Here ...
The Frauchiger-Renner argument: A new no-go result?
(Elsevier, 2020-05)
In April 2016, Daniela Frauchiger and Renato Renner published anarticle online in which they introduce a Gedankenexperiment that led them to conclude that single-world interpretation of quantum theorycannot be self-consistent. ...
Crustal collapse in the Andean backarc since 2 Ma: Tromen volcanic plateau, Southern Central Andes (36°40′-37°30′S)
(Elsevier Science, 2008-11)
Analysis of seismic lines and gravity data shows the existence of Quaternary extensional depocenters beneath thick covers of < 1 Ma-old volcanic rocks in the Tromen volcanic plateau backarc region (36°40′-37°30′S). Dating ...
