Humanidades, a place against oblivion. Etnography about tradition of the marks of memory and the revolution of words in La Plata - Argentina
2019
En este texto me interesa analizar la génesis de un proceso de memoria singular generado por y en la Facultad de Humanidades de Universidad Nacional de La Plata. Focalizaré la mirada sobre la instalación de una placa con los nombres de desaparecidos en la Facultad de Humanidades de La Plata y sus derivaciones en el cambio de la institución universitaria a un predio donde había funcionado el ex Centro Clandestino de Detención BIM 3, para finalmente detenerme en la lucha por una pared donde se dirimieron y dirimen posturas políticas y conflictos de memoria a partir de tres murales. Estos pequeños actos que producen y resignifican un lugar de memoria peculiar, permiten desnaturalizar la idea d…
Memories, forgetting and silences in the museographical proposal of the memory center “La Perla”
2019
El artículo analiza el proceso de selección y consagración de memorias en un caso particular: el del Espacio para la Memoria que funciona en lo que durante la última dictadura en Argentina (1976-1983) fue el Centro Clandestino de Detención (CCD) conocido como “La Perla” en la provincia de Córdoba, Argentina. El mismo analiza las funciones que fue asumiendo el lugar: CCD, cuartel militar, espacio de memorias, y los valores que diferentes grupos y el estado le adjudicaron a lo largo de su historia. A partir de allí, aborda las propuestas elaboradas para su institucionalización como espacio de memoria, la elaboración del guion del museo de sitio y las muestras exhibidas, profundizando en el ju…
Remembering and Forgetting, Discovering and Cherishing
2018
The events of the Second World War left considerable material remains in Finnish Lapland, ranging from the remnants of structures that were destroyed in the 1944–45 Lapland War, through to small, portable objects connected to soldiers, prisoners of war and civilians. These material remains have variously been saved and cherished by survivors and their families, disregarded as ‘war junk’, ‘discovered’ by hobbyists exploring the landscape, amassed and exchanged by private collectors, and accessioned into official museum collections. These various processes represent transformations of material culture to take on various meanings and embodiments, depending on the different individuals and orga…
Compatibility between traditional ground layers and 3D printing materials
2018
Starting point of this work was the restoration of a Panel Painting depicting the Adoration of the Shepherds with a Saint Bishop, by an unknown author, stored in the Galleria Regionale della Sicilia di Palazzo Abatellis, in Palermo. It was decided to integrate a missing angular decorative element of the painting’s frame in order to restore the integrity of the frame by reverse engineering and 3D printing. Reintegration was feasible as the frame has a modular decorative pattern and the remaining three corners were available. Reverse engineering and 3D printing techniques have been used in order to find a solution according to the principles of recognition, reversibility and compatibility. Mo…
Un códice facticio de cancioneros manuscritos del siglo XVI
2020
Se ofrece un completo análisis codicológico del manuscrito 2763 de la Biblioteca Universitaria de Salamanca. Se trata del volumen denominado SA10 en el sistema de siglas propuesto por Brian Dutton (1990-91), un códice que agrupa dos cancioneros manuscritos independientes de poesía medieval, fechables en la primera mitad del siglo XVI. El estudio exhaustivo de la estricta materialidad del códice se completa con el recuento y análisis de las obras y autores seleccionados, así como de su disposición y secuenciación. Los resultados permiten formular una hipótesis argumentada acerca de la génesis del volumen y de su complejo proceso de copia y transmisión. A complete codicological analysis of ma…
On the mechanical behavior of BFRP to aluminum AA6086 mixed joints
2013
The aim of this work is to analyze the possibility to join aluminum alloy AA6086 and composite laminates reinforced with basalt fibers, an innovative material which use is growing in several applications as an alternative to glass fibers. To this goal, three joining techniques were investigated: mechanical by Self Piercing Riveting (in the next called SPR), adhesive by co-curing technique and mixed in which the joining techniques (i.e. adhesive and mechanical) were combined. Two manufacturing technologies (i.e. hand lay-up and vacuum bagging) were used both to produce composite substrates and to realize co-curing adhesion between the substrates to be joined. Mixed joints were realized by in…
Bilayer biodegradable films prepared by co-extrusion film blowing: Mechanical performance, release kinetics of an antimicrobial agent and hydrolytic …
2020
Abstract Bilayer biodegradable, eco-friendly films were prepared by co-extrusion film blowing, coupling polylactic acid (PLA) and Bio-flex ® (BIO). Furthermore, in the PLA layer, carvacrol (CRV) was added as a natural antimicrobial additive, whereas a nanoclay (D72T) was integrated to protect CRV from volatilization and to modulate release. The materials were analyzed by morphological, chemical-physical, mechanical testing. Furthermore, CRV release and degradation tests were performed. The results pointed out that coupling the two matrices allows gathering the stiffness of PLA with the ductility of BIO. Furthermore, the interlayer adhesion is promoted by CRV. D72T exerts a key-role in avoid…
On the response of flax fiber reinforced composites under salt-fog/dry conditions: Reversible and irreversible performances degradation
2022
Abstract Despite their scarce resistance to humid or wet conditions, natural fiber reinforced composites (NFRCs) seem to be able to partially recover their performances under discontinuous exposition to marine environment. To investigate this peculiarity, flax fiber reinforced composite was at first subjected to salt-fog spray condition at 35 °C for 15 and 30 days, respectively, and then stored in ‘‘dry” condition (i.e., 50% R.H. and 22 °C) between 0 and 21 days. The performances evolution was evaluated through flexural tests, water uptake and contact angle measurements. Moreover, the morphology of fractured mechanical samples was examined by using 3D optical microscope and scanning electro…
Architectures “on ruins” and ambiguous transparency: the glass in preservation and communication of archaeology
2008
Abstract The contemporary architecture is characterized by an even more marked transparency, as a result of a continuous experimentation all directed towards the search of the built “lightness”, that is towards the “dematerialization” of the architecture and the consequent loss of weight connected to the excess of form. It is in 1851 that a New Architectural Age springs because of the realization of the Crystal Palace, in London – that has addressed towards the experimentation of the glass as an architectural, structural element and of design. Today, part of this experimentation has been applied for some interventions of coverage, protection and communication in situ of the archaeological r…
Archives and documents in the digital age
2017
Este artículo se propone reflexionar sobre algunas de las características del nuevo orden digital. En particular, se centra en las mutaciones que afectan a los conceptos de archivo y documento, así como a sus rasgos más destacados. Partiendo del hecho de que estos registros son fundamentales para cualquier estudioso del pasado, indaga sobre las consecuencias de su desmaterialización. Se examina el significado de ese espacio en algunas de sus dimensiones y se subraya la evidente paradoja que supone conservar y estudiar objetos o datos que son efímeros por naturaleza y que, en su mayoría, nacieron para morir rápidamente. The paper aims to examine and explore on some of the characteristics of …
