Temporal analysis of side effects produced by foam agents in the soil excavated with Earth Pressure Balance (EPB)
(2015-11-15)
Abstract. The use of foaming agents, is a tunneling technique frequently used with Earth Pressure Balance (EPB) Tunnel Boring Machine (TBM). The main objective of the Materials and Processes for Sustainable Construction ...
Seismic earth pressures on retaining structures and basement walls in cohesionless soils
(African Society of Civil Engineering, 2016)
Observations of the performance of basement walls and retaining structures in recent earthquakes show that failures of basement or deep-excavation walls in earthquakes are rare even if the structures were not designed for ...
Medición del coeficiente de presión de tierras en reposo “Ko”, por medio del consolidómetro de Rowe modificado

Earthquake-induced pressures on discontinuous piling support on Santiago gravel
(ELSEVIER SCI LTD, 2012)
Discontinuous anchored piling support (anchored soldier piles without lagging) is one of the most frequent earth-retaining systems used in temporary deep excavations in Santiago, Chile. The main advantages of using ...
Point defects in MgO.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
The Earth's mantle is composed mainly by MgO, known as periclase, which has a simple rock-salt structure with perfectly octahedral cation sites. Point defects in this material, such as vacancies and isolated impurities, ...

Sensitivity of the tropical climate to an interhemispheric thermal gradient: the role of tropical ocean dynamics
(European Geosciences Union, 2018)
This study aims to determine the role of the tropical ocean dynamics in the response of the climate to extratropical thermal forcing. We analyse and compare the outcomes of coupling an atmospheric general circulation model ...
alpha-SiAlON-SiC composites obtained by gas-pressure sintering and hot-pressing
(Elsevier B.V., 2007-07-06)
The objective of this work was the obtaining in situ of alpha-SiAlON-SiC composite, using an alternative rare-earth oxide mixture, RE2O3, as sintering additive, by two different sintering processes. As sintering additive, ...
