Google Sketchup

This is a first approach to the application of virtual reconstruction techniques of a colonial house. In Argentina it is still uncommon to perform 3D modeling of archaeological sites and especially in historical archeology. As a first step, we used the Google SketchUp to model the country house located on the banks of the Río de la Plata (Buenos Aires). It has historical significance because it belonged to a Spanish councilman, housed hundreds of slaves and was the place where stayed the troops that carried out the Second British Invasion of Buenos Aires. In this case, the 3D modeling was useful for evaluating the future excavationa and activities of preservation of cultural heritage.

The Village

From historical advice to 3D modeling and programming, the process of reconstructing cultural heritage sites populated with virtual inhabitants is lengthy and expensive, and it requires a large set of skills and tools. These constraints make it increasingly difficult, however not unattainable, for small archaeological sites to build their own simulations. In this article, we describe our attempt to minimize this scenario. We describe a framework that makes use of free tools or campus licenses and integrates the curricular work of students in academia. We present the details of methods and tools used in the pipeline of the construction of the virtual simulation of the medieval village of Mértola in the south of Portugal. We report on: a) the development of a lightweight model of the village, including houses and terrain, and b) its integration in a game engine in order to c) include a virtual population of autonomous inhabitants in a simulation running in real-time.

During the past years there has been the birth of significant projects about digitization and virtual preservation of cultural heritage. Such panorama offers great chance to develop 3D modeling for cultural heritage. 3D reconstruction offers a chance to digitize historic objects which are still extant, and also to reconstruct and visualize objects which are no longer extant and that can only be known from historic descriptions or depictions. The chapter focus on the latter aspect. In fact, 3D modeling of extant objects is technologically or logistically challenging but virtual reconstruction of non- or no longer- existent items adds more importance to interpretation of historic sources. This chapter illustrates the current situation taking into account the state of the art, the different suggestions in solving such kind of problem, and through up to date examples will suggest a possible unified method to give life to both lost buildings and never built ones. The goal is to find common points with other similar cases, to obtain a common procedure an to suggest ways of development.

Antiquities Trade

One of the greatest disasters for African archaeology is the systematic plundering of archaeological sites for the antiquities trade (e.g. Schmidt & McIntosh 1996; ICOM 1994). An eloquent proof of this plundering is the beautiful catalogue ‘Earth and ore’, published in 1997 by Schaedler. Of the 668 objects illustrated fullcolour in this catalogue all come, except for a dozen objects and some forgeries, from recent looting of sites in Mali, Niger, Burkina Faso, Chad, Ghana and Nigeria.Regions in Mali that are particularly rich in cultural heritage, such as the Niger Inner Delta and the Dogon country, are particularly shocking examples of this systematic plundering. Archaeological research in 1991 in the south of the Delta, undertaken within the framework of the Malian-Dutch ‘Toguéré’ project of the Institut des Sciences Humaines at Bamako, showed that 450h of the 830 visited sites exhibited traces of illicit excavations (Dembele et al. 1993). In 1996, a sample of 80 of these sites was revisited by Annette Schmidt. The percentage of plundered sites had increased by 20%) (Annette Schmidt pers. comm.). One does not need much imagination to realize the scale of this disaster.

Coordination Action

The European amount of digitized material is growing very rapidly, as national, regional and European programmes support the digitization processes by museums, libraries, archives, archaeological sites, and audiovisual repositories. The generation of digital cultural heritage is accelerated also by the impulse of Europeana that is fostering the European cultural institutions to produce even more digital content. Moreover digital cultural heritage content are complex and interlinked through many relations. European countries are working for the future, in order to create a data infrastructure devoted to cultural heritage research. Currently, Europe have twin projects (DC-NET and INDICATE) ongoing and a new international coordination action is under preparation to design a validated roadmap for the preservation of digital cultural content. These initiatives are contributing to smooth the way to the Open Science Infrastructure for Digital Cultural Heritage, which is foreseen in 2020.

Virtual Reconstruction

The possibilities offered by photogrammetric reconstruction based on computer vision algorithms allowed in recent years to develop new interesting solutions for the use and dissemination of knowledge on Cultural Heritage (CH). In the same way, the recent technological development in the field of Virtual Reality (VR) has offered new possibilities for the creation of interactive virtual environments which can be freely accessed via the browser using any type of device. These technologies acquire an additional relevance if applied to archaeological sites or monuments that are difficult to access, or even totally inaccessible, except by specialized personnel. In this case the virtual fruition on web becomes strategic for the valorization of CH, as in the case of submerged archaeological sites, where the virtual tour represents in fact the only opportunity of diffuse accessibility. The present case shows the virtual reconstruction of the wreck area of the Roman ship found on the seabed of Cala Minnola on the island of Levanzo (TP, Italy). The model, obtained from a Structure from Motion (SfM) processing of a chunk of photos originally intended for a traditional photogrammetric survey, was edited and inserted into a specific template based on HTML5 and linked to Javascript libraries (Three.js) which allowed browsing on web. Subsequently, the navigation model was appropriately adapted to the purpose, so as to make the use of the network more intuitive possible, considering any type of device and using the most common browsers (Chrome, Safari, Firefox). This experimentation is a viable procedure for spreading the knowledge of a submerged archaeological site in a simple way, by web-browsing. This type of navigation models with the future development of 5G networks will find greater diffusion and application, with the possibility of including increasingly complex environments in the navigation.

El cinturón verde hortícola del Gran Buenos Aires y Gran La Plata comprende una amplia franja imaginaria trazada tomando como centro la ciudad de Buenos Aires. Se cultivan una gran variedad de hortalizas, entre las que se destacan: tomate, pimiento, lechuga y frutilla, entre otras. Las mismas son cultivadas en condiciones de campo 6 bien en ambientes protegidos, modalidad de producción que ha crecido en los últimos años. El cultivo de tomate, típico de la zona platense, ha incrementado en estos años la superficie de cobertura y por consiguiente la producción. Entre las numerosas plagas que atacan este cultivo, se destacan las arañuelas tetraníquidas y en especial Tetranychus urtícae. En nuestro país estos ácaros son combatidos tradicionalmente con la aplicación de acaricidas y en países europeos y los Estados Unidos mediante la combinación de acaricidas y ácaros predadores de la Familia Phytoseiidae. Este grupo de acarófagos ha sido empleado exitosamente en numerosos cultivos (poroto, pepino, frutilla, manzano) aunque con resultados dudosos sobre tomate. El efecto de las plantas sobre los niveles tróficos superiores ha sido ampliamente documentado. El tomate, mediante la presencia de pelos glandulares ó la emanación de compuestos volátiles inhibe o estimula, dependiendo de las especies, las interacciones entre los herbívoros y los enemigos naturales. Dentro de este contexto, se realizaron estudios tendientes a analizar el papel que la pilosidad del tomate tiene sobre la supervivencia, fecundidad y en la interacción establecida entre T.urtícae y Neoseíu1us calífornicus.

La actividad de la enzima ácido δ-aminolevulínico dehidrasa (ALA-D) es un reconocido biomarcador específico de exposición a plomo. Debido a sus características ha sido utilizado en estudios de monitoreo ambiental para evaluar la exposición a plomo en diversos organismos, entre ellos peces. El principal objetivo del presente trabajo de tesis fue validar un método de evaluación general de riesgo ecotoxicológico por exposición a plomo en poblaciones naturales de peces. Para tal fin se seleccionaron tres especies recolectadas del río de la Plata: Prochilodus lineatus (sábalo), Leporinus obtusidens (boga) y Cyprinus carpio (carpa). Las zonas de muestreo elegidas fueron: Berazategui y Berisso ubicadas cerca de las emisiones de residuos cloacales provenientes de las ciudades de Buenos Aires y La Plata. La tercera, Atalaya, libre de emisiones cloacales, pero sujeta a emisiones diversas, todas ellas, de origen antropogénico. Los muestreos se realizaron entre junio de 2002 y mayo de 2004. En primera instancia se caracterizaron diversos parámetros de la enzima ALA-D en muestras de sangre y de tejido hepático. Los resultados obtenidos mostraron características similares en la enzima sanguínea de todas las especies estudiadas. Lo mismo se observó para la enzima hepática. La comparación entre tejidos mostró diferencias en el valor de Km, siendo menor para la enzima hepática. Posteriormente, se procedió a validar el uso de la enzima como parámetro biomarcador de exposición a plomo en estudios de campo.
