Lo Poroso y la Ciudad. "Denkbilder, Epifanías en Viajes" de Walter Benjamin
(Universidad de Costa Rica, 2013)
Influence of the scale range width on the determination of the hydraulic conductivity and effective porosity. The case of a porous aquifer in southern Italy
(USFQ PRESS, departamento editorial de la Universidad San Francisco de Quito USFQ, 2019)
Dynamic reduced model and stochastic aspects for PFGM curved beams with variable curvature
(Pergamon-Elsevier Science Ltd, 2021-01)
In this paper a new 1D finite element model for dynamic calculations of PGFM curved beams with variable curvature is developed. The reduced high-speed calculation model allows stochastic aspects in the dynamic of the ...
A sigmoidal equation for the high strain rate compression of porous metals
(Pergamon-Elsevier Science Ltd, 2020-03)
The high strain rate compression of porous materials is a problem that presents a series of difficulties to continuum-scale codes, its computational cost being a major one. Following previous contributions suggesting that ...
Zero-thickness interface constitutive theory for concrete self-healing effects
(Pergamon-Elsevier Science Ltd, 2017-07)
A damage-plasticity constitutive theory for zero-thickness interfaces is presented aimed at predicting time-dependent self-healing phenomena in concrete. The material model is based on fracture-energy concepts and accounts ...
Influence of porosity on high-velocity mass-asymmetric collisions
(Wiley Blackwell Publishing, Inc, 2020-02)
Using granular mechanics, we study the influence of porosity on the collisions of spherical granular aggregates with a mass ratio of around 60. At high filling factors, the projectile produces a crater on the target, similar ...
Effect of radial velocity profiles on axial dispersion in packed beds: asymptotic behaviour
(Brazilian Society of Chemical Engineering, 2021-09)
Axial dispersion of a solute in a flow through packed beds arises from molecular diffusion, velocity variations at the interstitial-pore scale and systematic radial velocity profiles. Currently, there is not a widely ...
Successful application of a commercial cationic surfactant mixture (benzalkonium chloride) as porosity stabilizer in porous carbons fabrication
(Elsevier Science, 2016-11)
Porous carbons (BSPCs) were obtained by carbonization of resorcinol-formaldehyde gels in the presence of cationic surfactants mixture (benzalkonium chloride) which act as porosity stabilizer. The application of an inexpensive ...
