    Adsorption Equilibrium and Kinetics of the Parex' Feed and Desorbent Streams from Batch Experiments

    Publicação
    The adsorption of the main components of the Parex process, i.e., p-xylene, m-xylene, o-xylene, ethylbenzene, p-diethylbenzene, and toluene, was studied in a batch adsorber operating under the conditions of an industrial unit (177 degrees C, 9 bar). Prior to each experiment, the faujasitic-type adsorbent was pretreated under helium flow to control the hydration level of the adsorbent. The experimental uptake curves were used to determine adsorption equilibrium data, which were fitted with Langmuir-type isotherms. A mathematical model in which the macropore diffusion is the rate-controlling mechanism, satisfactorily describes the experimental uptake curves.

    Cláudio Manuel da Costa, Pope e Vergílio: a propósito da tradução de uma écloga

    Publicação
    The article discusses an unpublished translation, probably written by Cláudio Manuel da Costa, of Messiah: a sacred eclogue, in imitation of Virgil's Pollio, by Alexander Pope. In addition to studying the translation - which has a prose and a verse version -, the edition of the manuscript is also presented.

    Experimental and numerical assessment of confined infill walls with openings and textile-reinforced mortar

    Publicação
    This work's primary objective is to present an experimental campaign, comprised of three full-scale in-plane tests. It was assessed the effect of the openings (central window) and of using textile-reinforced mortar strengthening. The slenderness is also studied by comparing the results herein obtained with other test existing in the literature. The masonry infill walls were built with horizontal hollow clay bricks. All the tests consisted of applying cyclic (loading-unloading-reloading) history of imposed displacements in the in-plane direction employing a top horizontal load. The mechanical properties of the adopted materials are characterized and presented. The results will be presented in terms of in-plane force-displacement responses, damage evolution and energy dissipation capacity. A literature review of numerical modelling approaches to simulate the masonry infill walls seismic behaviour was provided after that. In the end, the experimental tests were simulated in the software OpenSees through a simplified modelling approach. The openings reduced the in-plane maximum strength and energy dissipation capacity by about 40% and 18%, respectively. On the other hand, the textile-reinforced mortar increased the initial stiffness, maximum peak strength and energy dissipation capacity by about 31%, 15% and 38%, respectively.
