Stainless steel grids for confinement of clay brick masonry columns
2016
This work presents the results of an experimental investigation on the behavior of 21 solid clay brick columns internally strengthened by stainless steel grids placed in the horizontal joints of mortar. This reinforcing technique can be applied as a constructive technique for new construction or as a retrofitting technique for existing structures (old structures to be reconstructed by original constructive method and internal reinforcement). Monotonic compressive loading tests were carried out under concentric and eccentric load. The effects of different numbers of steel grids and eccentricity of the external load were examined. Also, a detailed characterization of the constituent materials…
Experimental Investigation on the Compressive Behaviour of Clay Brick Masonry Columns Confined by BFRP or Steel Wires
2016
This paper presents the results of an experimental research aiming to investigate on the compressive behavior of full size clay brick masonry columns reinforced with Basalt Fiber Reinforced Cementitious Matrix (BFRCM) or with steel wires collaring. Uniaxial compressive tests were performed on eight retrofitted columns and four control specimens. Two masonry strength were considered by varying the mortar grade. Results are presented and discussed in terms of axial stress-strain relationships, failure modes and crack patterns of the specimens tested up to failure. For the limit of investigated variables, comparisons with unreinforced specimens show the ability of these alternative techniques …
Use of FRP fabrics and stainless steel grids for strengthening brick masonry columns
2016
This work presents the results of an experimental investigation on 42 solid clay brick columns internally strengthened by FRP fabrics or stainless steel grids placed in the horizontal joints of mortar. Monotonic compressive loading tests were carried out under concentric and eccentric load. Eccentric tests were carried out loading the specimens on a reduced area with respect to the entire crosssection producing a D-region. The reinforcing of every course and of alternate courses are studied. The effectiveness of the proposed strengthening techniques is discussed, in terms of increase in strength and energy required to the collapse of brick columns. An analytical expression is proposed that …
La Biología Sintética; reto biotecnológico y bioético en las Ciencias de la Vida
2020
[ES] La Biología Sintética supone un reto científico y bioético de futuro, tanto a nivel medioambiental, como también en el mejoramiento humano y de otras especies. Por ello, el trabajo abordará dos aspectos principalmente. La síntesis en el laboratorio de células artificiales para la fabricación de un principio activo farmacéutico y por otra parte la reflexión bioética acerca de la potencialidad de dichas técnicas, advirtiendo la diferencia en los límites de la síntesis de vida y creación de vida. Actualmente, se calcula que hay 1.7 millones de especies conocidas de las 14 millones que se estima en la naturaleza. En los últimos 10 años se han generado más de 3000 patentes de organismos gen…
Maiolica bricks spires and domes in Sicily.Tipology, constructive and decorative elements
2018
The use of maiolica bricks as artefact for surface decoration is widespread both in monumental and ordinary architectures in the Mediterranean regions, harmonizing the local construction traditions with the Islamic influences. This study presents an in-depth analysis of examples of spires and domes in Sicily featuring earthenware maiolica cladding serving both as decoration and structural element. Due to the limited knowledge of these artefacts, incautious construction operations led to an alteration of their material and technical features, putting at risk a centuries-old heritage. The systematic investigation on more than a hundred samples categorises these architectural polychrome elemen…

“She Isn’t Going to Give Up”: Women’s Resilience in Monica Ali’s Brick Lane – A Feminist Reading
2019
Abstract While Monica Ali’s novel Brick Lane is most often analyzed from the vantage points of postcolonialism as a text dealing primarily with the plight of the Bangladeshi immigrant community in London, it is difficult, if not downright impossible, to overlook the crucial role women and feminine resilience (in the face of not only patriarchy, but also racism, religion and social unrest) play in the novel. In actual fact, the story can much easier be read as the plight of women in their quest for self-determination and identity than as a novel about cultural clashes in the multicultural metropolis. The present essay sets out to prove that feminism is actually at the forefront of Ali’s nove…
Material sources of the Roman brick-making industry in the I and II century A.D. from Regio IX, Regio XI and Alpes Cottiae
2015
International audience; Bricks, fine pottery, ceramic gears and tiles are among the human-made objects routinely recovered in archaeological documentation. Sites associated with early civilizations can provide thousands of samples from a single excavation. They come in endless varieties according to economic and social circumstances and, as debris can last almost forever, provide important clues about the past behaviours in human societies. Any information about the provenance of ceramics is highly valuable in archaeological analysis. In the case of Roman brick-making, the provenance and manufacture of clayey materials are usually interpreted only by studying stamps imprinted on the artefac…
