Biostratinomy of terrestrial macromammals in Doñana National Park (Spain)

  • Bernáldez Sánchez, Eloísa
There is no scientific guarantee that vertebrate remains preserved in archaeological and palaeontological sites are a representative sample of the palaeocommunity they belonged to, or that they formed a part of the preferences of man consumption since they are mainly waste deposits. We do not know the qualitative and quantitative consequences of pre-depositional processes of trophic activity of human population and of any other carnivore and scavenger that could have affected them. As a consequence of this, we performed a biostratinomic study of the carcasses assemblage scattered throughout the Doñana Biological Reserve in order to know if there is a preservation general dynamics, with general patterns that can be applied to the taphonomic study of archaeological sites.

Assessing sustainability within territorial and urban heritage : an indicator-based evaluation in the case of medium-sized cities in inner Andalusia

  • Espino Hidalgo, Blanca del
The purpose of this paper is to develop a methodology to assess urban sustainability within built, urban, territorial and landscape heritage, considering that cultural heritage has recently emerged as one of the keys of urban and territorial sustainability due to its inherent properties of durability and adaptability to changes over time. The implementation pivots on a case study based on medium-sized historical cities. Both academic and official documents consider this urban category as particularly likely to demographic, environmental and economic sustainability.

Development of a TiNbTaMoZr-Based High Entropy Alloy with Low Young´s Modulus by Mechanical Alloying Route

In this work, an equiatomic TiNbTaMoZr-based high-entropy alloy (HEA) has been developed by a powder metallurgy route, which consists of a process of combined one-step low-temperature mechanical milling starting from the transition metals as raw materials and a subsequent pressureless sintering. In this way, the optimized synthesized specimen, after 10 h of milling time, showed two di erent body-centered cubic (bcc) TiNbTaMoZr alloys, which, after sintering at 1450 C, 1 h of dwell time and a heating and cooling rate of 5 C min􀀀1, it remained formed as two bcc TiNbTaMoZr-based HEAs. This material, with micrometric and equiaxed particles, and with homogeneously distributed phases, presented a Young’s modulus that was significantly higher (5.8 GPa) and lower (62.1 GPa) than that of the usual commercially pure (cp) Ti and Ti6Al4V alloy used for bone-replacement implants. It also presented similar values to those of the HEAs developed for the same purpose. These interesting properties would enable this TiNbTaMoZr-based HEA to be used as a potential biomaterial for bulk or porous bone implants with high hardness and low Young´s modulus, thereby preventing the appearance of stress-shielding phenomena.

Technological characterization of polychromies on a Balearic medieval stone altarpiece of the 15th century

  • Bosch Rubio, Llucia
  • Gómez Morón, Auxiliadora
  • Ortiz Calderón, Pilar
The objective of this research is to encrease the historical, artistic and material knowledge of the polychrome finishes in a medieval stone altarpiece within the context of the island of mallorca. There are many examples of Gothic art introducing polychrome finishes on stone sculpture, both in the religious and civil sphere in the Iberian Peninsula. In the Balearics, with the Christian conquest, this practice was also extended. The Passio Imaginis Altarpiece (1448-1453), located at San salvador Sanctuary in Felanitx (mallorca) has been studied. The characterization of the polychromies began with an organoleptic examination and photograph of general visible light and flush, assessed by digital image analysis (DIA). DIA allowed to reveal traces of polychromies that had not been detected by nacked eye in order to carry out the proper sampling. The samples were analyzed by optical microscopy (OM); scan electron microscopy (SEM-EDX), and the study of organic binders. The results obtained in the stratigraphic studies revealed the application of a sequence of layers with pigments employed in Iberian Peninsula. Binders detected are egg or animal glue. data indicates that it is most likely an original finish. Colour study contributes through the knowledge of the Passio Imaginis altarpiece and the awareness of its remains, to avoid the interpretation and/or destruction of the pictorial strata present in stone carvings.

Preventive conservation requires identification evaluations, and prioritization of the maintanance and restoration of cultural heritage under different hazards. The degradation of monuments is due to the effects caussed by different agents (earthquakers, floods, weathering, pollutions agents, anthropogenic factors) that produce total or partial losses of architectonic elements or their alterations. The conservation degree of each monument depends on the vunerability, and its index is an indirect function of the level of deterioration, whereas the hazards depend on the localization and its environment conditions, social development and anthropogenic agents. RIVUPH and Art-Risk are Spanish projects based on the analysis of environmental risk in historical cities and models to assess vulnerability and lives of buildings in order to improve the preventive conservation of monuments with similar characteristics. For this purpose, two different approaches have been evaluated: DELPHI method and Fuzzy Logic, where both tools are based on the opinion of experts in the field. The vulnerability analysis of three churches of Seville (Spain) have been studied to assess the monuments conservation degree. Both models (DELPHI and Fuzzy Logic) are able to forecast the necessities of restoration overlapping different scenarios

This contribution aims to deepen the formulas for the application of 3D modelling tools in their application to the protection of heritage in the Spanish legislative framework: Although they emerge as instruments for their eminently industrial application, new architecture or infographics, the Rhinoceros software, together with the Vray rendering engine, constitute a tandem that has proved to be very useful for determining the degrees of impact (heights, perspectives, buildability, occupation and other urban parameters) in real estate environments declared to be of "Cultural Interest" (from now on referred to as "BIC" - or Asset of Cultural Interest), according to the regional legislation of Andalusia. In addition to the didactic character of the results, which allows their dissemination as teaching material applied in the Degree in Fundamentals of Architecture of the University of Seville, the three case studies presented facilitate the reading of the environment affected by the specific regulations, as well as the technical determination of the visual pollution that the surrounding buildings cause in the building itself. The three case studies include buildings declared "BIC", which are in very different situations of conservation and use, all in the city of Seville, in the south of Spain: while the City Council, which presides over the most important square in the city, is the paradigmatic model of a dynamic and inhabited square, the Atarazanas (former shipyard factory) are in a good state of conservation, but without defined use. The last case, the extinct convent of San Agustin, in addition to not being used, is in a state of ascending deterioration, since a large part of its construction has disappeared thanks to real estate expansion and the absence of legislative protection of the heritage.

Research-action on the heritage object : methodologies for approximation and teaching experiences at the final degree project course in the School of Arquitecture of Seville

The course Proyecto Fin de Grado taught at the Degree in Architecture of the University of Seville was implemented in the academic year 2015-2016. It is conceived as a practical subject that follows a dynamic workshop in which students expose weekly the progress of their project with the supervision of eight teachers, one per area of knowledge. This work deals with the results obtained in the academic year 2016-2017 in relation to the intervention projects in Heritage. Working on a Cultural Property inexorably requires the prior generation of exhaustive knowledge about it. From this perspective, the teaching teams of groups 6.01 and 6.07 - of which the authors of this communication are part - understand that this is an essential preliminary stage that will allow the students to base their architectural discourse of intervention on the heritage values detected and the diagnosis of the state of conservation of what exists. This vision also requires assuming that the interest of the exercise is subordinated to the methodological process developed by the student, inasmuch as it should serve them to analyze and evaluate with coherence each one of the project decisions adopted. Despite the complexity of these exercises, it has been detected that, firstly, a high percentage of students choose to develop this type of project; secondly, it requires the participation of the different areas involved in the teaching of the subject; and thirdly, the academic results are generally more satisfactory.

Using BIM and GIS to Research and Teach Architecture [en línea]

  • Ferreira-Lopes, Patricia
This paper describes the use of BIM and GIS in our research of architectural heritage and the experience gained from their implementation from Year 1 to Year 5 in the subjects “Drawing and Machine” and “Drawing 3, Graphical Analysis” taught in the Department of Architectural Graphical Expression of the Seville School of Architecture during the academic years 2014/2015 and 2015/2016. We propose a transition towards a teaching model that integrates analogue and digital with a gradual and coherent approach based on an understanding of architecture itself as a complex system made up of various elements and attributes, both visual and alphanumeric, which allow the “graphical” to transcend the visual and incorporate different types of information

Tota Pulchra (around 1600), a high quality copy of a painting made by an anonymous artist copying probably an Italian painter Giuseppe Cesari, was recently restored due to its bad conservation state. Before and during its intervention, the artwork was analysed in order to get information about materials and painting technique and help at the restoration process. Several invasive and non-invasive techniques for material identification have been used. Extracted samples were studied with OM, SEM-EDX, FTIR and GC-MS. The results revealed the usual palette for the 16th century, linseed oil binder, chalk based preparation and a complex pigment mixture for priming, as well as several later interventions. Under the OM, also organic fibers from the canvas were identified as flax support for the painting.
