3D investigation and modeling of the geometric effects on porosity in packed beds

open access: yesAIChE Journal, EarlyView.
Abstract In porous beds, physical boundaries restrict particle arrangement, leading to inhomogeneous porosity. This paper reports on the porosity profiles that are the result of geometric effects on monodisperse packed beds in cylindrical and cubic arrangements. Special focus is given to the influence of edges and corners in cubic geometries.

Experimental validation of the RESPONSE framework against cyberattacks on cyber‐physical process systems

open access: yesAIChE Journal, EarlyView.
Abstract This work experimentally validates the RESPONSE (Resilient Process cONtrol SystEm) framework as a solution for maintaining safe, continuous operation of cyber‐physical process systems under cyberattacks. RESPONSE implements a dual‐loop architecture that runs a networked online controller in parallel with a hard‐isolated offline controller ...

La naturaleza social de los desastres asociados a inundaciones y deslizamientos en Medellín (1930-1990).

open access: yesHistoria Crítica, 2011
This article qualitatively links the disasters associated with landslides and flooding in Medellin with characteristics of the process of urban growth, such as double marginality and the intensive transformation of nature.

Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

open access: yesAIChE Journal, EarlyView.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

Channeling episodes of Kasei Valles, Mars, and the nature of ridged plains material [PDF]

open access: yes
The geologic mapping compiled at 1:500,000 scale of the northern Kasei Valles area of Mars (MTMs 25062 and 25067) indicates (1) at least three periods of Kasei Valles channeling, (2) the development of Sacra Fossae (linear depressions on Tempe Terra and ...
