    Cultural Heritage all over the world is at high risk. Natural and human activities endanger the current state of monuments and sites, whereas many of them have already been destroyed especially during the last years. Preventive actions are of utmost importance for the protection of human memory and the prevention of irreplaceable. These actions may be carried out either in situ or virtually. Very often in situ preventive, or protective or restoration actions are difficult or even impossible, as e.g. in cases of earthquakes, fires or war activity. Digital preservation of cultural heritage is a challenging task within photogrammetry and computer vision communities, as efforts are taken to collect digital data, especially of the monuments that are at high risk. Visit to the field and data acquisition is not always feasible. To overcome the missing data problem, crowdsourced imagery is used to create a visual representation of lost cultural heritage objects. Such digital representations may be 2D or 3D and definitely help preserve the memory and history of the lost heritage. Sometimes they also assist studies for their reconstruction. An initiative to collect imagery data from the public and create a visual 3D representation of a recently destroyed stone bridge almost 150 years old is being discussed in this study. To this end, a crowdsourcing platform has been designed and the first images collected have been processed with the use of SfM algorithms.

  3. Mineralogy and cultural heritage.

    2010-01-01

    In recent years there has been an escalation in the number of mineralogical studies involving cultural heritage materials. A number of factors have contributed to this exponential growth, including the shrinking budgets in traditional research fields, which forced the expansion of applications of mineralogical methods to novel research areas. Mineralogy as a discipline is traditionally connected to geology, petrology, and geochemistry, although it also has the strong tendency to embody the methods and techniques of modern crystallography and advanced materials science. Arguably, this makes it ideally suited and well equipped to meet the demanding challenges posed by archaeometric analysis and conservation problems. A few case studies linking mineralogy and archaeometry are discussed. PMID:21138159

    This paper on providing "oo-information" (= objective object-information) on cultural monuments and sites, based on 3D photographs is also a contribution of CIPA task group 3 to the 2013 CIPA Symposium in Strasbourg. To stimulate the interest in 3D photography for scientists as well as for amateurs, 3D-Masterpieces are presented. Exemplary it is shown, due to their high documentary value ("near reality"), 3D photography support, e.g. the recording, the visualization, the interpretation, the preservation and the restoration of architectural and archaeological objects. This also includes samples for excavation documentation, 3D coordinate calculation, 3D photographs applied for virtual museum purposes and as educational tools. In addition 3D photography is used for virtual museum purposes, as well as an educational tool and for spatial structure enhancement, which in particular holds for inscriptions and in rock arts. This paper is also an invitation to participate in a systematic survey on existing international archives of 3D photographs. In this respect it is also reported on first results, to define an optimum digitization rate for analog stereo views. It is more than overdue, in addition to the access to international archives for 3D photography, the available 3D photography data should appear in a global GIS(cloud)-system, like on, e.g., google earth. This contribution also deals with exposing new 3D photographs to document monuments of importance for Cultural Heritage, including the use of 3D and single lense cameras from a 10m telescope staff, to be used for extremely low earth based airborne 3D photography, as well as for "underwater staff photography". In addition it is reported on the use of captive balloon and drone platforms for 3D photography in Cultural Heritage. It is liked to emphasize, the still underestimated 3D effect on real objects even allows, e.g., the spatial perception of extremely small scratches as well as of nuances in color differences

    2013-07-01

    When you think about the Architecture, Engineering and Construction (AEC) Industry people tend to refers to new buildings, but nowadays the recovery of existing ones is increasingly the subject of the research. The current historical context raises this issue at the center of numerous thought due both to economic and environmental conditions. So, the need to refurbish the cultural heritage is becoming more important than the construction of new buildings. Modern technologies allow professionals to do this to turn the buildings into structures capable to meet the users' confort with a considerable energy saving. Italy is trying to make a change to the construction industry through the national InnovANCE project, which aims to develop the first national database able to share information among professionals through the help of Building Information Modeling (BIM). In this way the subject involved in a construction process can update their way of working, with a consequent time and cost saving. This paper aims to present the way in which the InnovANCE project can be considered as the key for Italy to change the way to conceive the building industry, using a case study such as the old thermal power of Politecnico di Torino, starting from the survey step. The methodology followed to obtain the 3D model will be described, starting from the data of a topographic and a laser scanner survey and from an archival documents research.

    2016-02-01

    During the last three decades, DNA analysis on degraded samples revealed itself as an important research tool in anthropology, archaeozoology, molecular evolution, and population genetics. Application on topics such as determination of species origin of prehistoric and historic objects, individual identification of famous personalities, characterization of particular samples important for historical, archeological, or evolutionary reconstructions, confers to the paleogenetics an important role also for the enhancement of cultural heritage. A really fast improvement in methodologies in recent years led to a revolution that permitted recovering even complete genomes from highly degraded samples with the possibility to go back in time 400,000 years for samples from temperate regions and 700,000 years for permafrozen remains and to analyze even more recent material that has been subjected to hard biochemical treatments. Here we propose a review on the different methodological approaches used so far for the molecular analysis of degraded samples and their application on some case studies. PMID:27572991

    2009-04-01

    The present study considers the use of a nanosecond pulsed laser setup capable of performing laser induced breakdown spectroscopy (LIBS) and pulsed Raman spectroscopy for the study of multilayered objects in the field of cultural heritage. Controlled etching using the 4th harmonic 266 nm emission of a Nd:YAG laser source with a 8 ns pulse duration was performed on organic films and mineral strata meant to simulate different sequence of layers usually found in art objects such as in easel and mural paintings. The process of micro ablation coupled with powerful spectroscopic techniques operating with the same laser source, constitutes an interesting alternative to mechanical sampling especially when dealing with artworks such as ceramics and metal works which are problematic due to their hardness and brittleness. Another case is that of valuable pieces where sampling is not an option and the materials to analyse lie behind the surface. The capabilities and limitations of such instrumentation were assessed through several tests in order to characterize the trend of the laser ablation on different materials. Monitored ablation was performed on commercial sheets of polyethylene terephthalate (PET), a standard material of known thickness and mechanical stability, and rabbit glue, an adhesive often used in works of art. Measurements were finally carried out on a specimen with a stratigraphy similar to those found in real mural paintings.

    Terahertz (THz) imaging is a relatively new non-destructive analytical technique that is transitioning from established application research areas such as defense and biomedicine to studies of cultural heritage artifacts. Our research adopts a THz medical imaging system, originally designed for in vivo tissue hydration sensing, to acquire high contrast imagery of painted plaster samples in order to assess the ability of the system to image the Byzantine wall paintings at the Enkleistra of St. Neophytos in Paphos, Cyprus. The original 12th century paintings show evidence of later painting phases overlapping earlier iconography. A thin layer of lead white (2PbCO3·Pb(OH)2) underlies, in parts, later wall paintings, concealing the original painting scheme beneath. Traditional imaging modalities have been unable to image the underlying iconography due to a combination of absorption and scattering. We aim to use THz imaging and novel optical design to probe beyond the visible surface and perform in situ analysis of iconography beneath the lead white layer. Imaging results of painted plaster mock-ups covered with a thin layer of lead white and/or chalk, as well as of a painted wooden panel with obscured writing, are presented, and from these images sufficient contrast for feature identification is demonstrated. Preliminary results from the analysis of these mock-ups confirmed the utility of this technique and its potential to image concealed original paintings in the Enkleistra of St. Neophytos. The results encourage analysis of THz scattering within paint and plaster materials to further improve spatial resolution and penetration depth in THz imaging systems.

  9. Cultural Heritage Applications of LIBS

    Anglos, Demetrios; Detalle, Vincent

    A versatile spectrochemical technique enabling nearly instant, multi-element analysis of materials, LIBS is increasingly employed in studies of archaeological and historical objects, monuments and works of art. The development of several mobile LIBS instruments opens a lot more possibilities for analytical campaigns on site: at museums, conservation laboratories and even outdoors at excavation sites or historical monuments. The basic concepts underlying the use of LIBS in the context of cultural heritage studies are briefly reviewed along with technical and instrumentation aspects. Selected examples of analytical studies are discussed with emphasis on cases that demonstrate the use of mobile LIBS instruments.

    The cultural heritage of a country includes, among other things, places, "buildings" and other monuments with historical value. It forms the identity of the country and is undoubtedly a national asset. For this reason, recording - documentation, protection, monitoring and management of cultural heritage is necessary. Different scientific and technological disciplines are involved in the study of cultural heritage. Photogrammetry and remote sensing, with their continuous scientific and technological advances, contribute substantially in this study. This paper refers to the above and includes a relevant example of Dodoni archaeological site, using VHR satellite data.

    Numerous cultural sites of the United Nations Educational, Scientific and Cultural Organization (UNESCO) world cultural Heritage are located in low-lying coastal regions. Because of anthropogenic global warming and induced sea level rise, many of these sites will be partially or totally flooded in the coming centuries/millennia. This is shown in a recent study by Marzeion and Levermann (2014 Environ. Res. Lett. 9 034001). Projecting future sea level rise and associated regional variability, these authors investigate which sites will be at risk. Because UNESCO cultural sites represent the common heritage of human beings and reflect the Earth and humanity history, they need to be protected for future generations.

    2015-09-01

    Taiwan is an important trading and maritime channels for many countries since ancient time. Numerous relics lie underwater due to weather, wars, and other factors. In the year of 2006, Bureau of Cultural Heritage (BOCH) entrusted the Underwater Archaeological Team of Academia Sinica to execute the underwater archaeological investigation projects. Currently, we verified 78 underwater targets, with 78 site of those had been recognized as shipwrecks sites. Up to date, there is a collection of 638 underwater objects from different underwater archaeological sites. Those artefacts are distributed to different institutions and museums. As very diverse management methods/systems are applied for every individual institution, underwater cultural heritage data such as survey, excavation report, research, etc. are poorly organized and disseminated for use. For better communication regarding to Taiwan's underwater cultural heritage in every level, a universal format of documentation should be established. By comparing the existing checklist used in Taiwan with guidelines that are followed in other countries, a more intact and appropriate underwater cultural heritage condition documentation system can be established and adapted in Taiwan.

    2016-04-01

    Over the past years, more and more collections belonging to archives, libraries, media, museums, and knowledge institutes are being digitised and made available online. These are exciting times for ALM institutions. They are realising that, in the information society, their collections are goldmines. Unfortunately most heritage institutions in the Netherlands do not yet meet the basic preconditions for long-term availability of their collections. The digital objects often have no long lasting fixed reference yet. URL's and web addresses change. Some digital objects that were referenced in Europeana and other portals can no longer be found. References in scientific articles have a very short life span, which is damaging for scholarly research. In 2015, the Dutch Digital Heritage Network (NDE) has started a two-year work program to co-ordinate existing initiatives in order to improve the (long-term) accessibility of the Dutch digital heritage for a wide range of users, anytime, anyplace. The Digital Heritage Network is a partnership established on the initiative of the Ministry of Education, Culture and Science. The members of the NDE are large, national institutions that strive to professionally preserve and manage digital data, e.g. the National Library, The Netherlands Institute for Sound and Vision, the Netherlands Cultural Heritage Agency, the Royal Netherlands Academy of Arts and Sciences, the National Archive of the Netherlands and the DEN Foundation, and a growing number of associations and individuals both within and outside the heritage sector. By means of three work programmes the goals of the Network should be accomplished and improve the visibility, the usability and the sustainability of digital heritage. Each programme contains of a set of projects. Within the sustainability program a project on creating a model for persistent identifiers is taking place. The main goals of the project are (1) raise awareness among cultural heritage institutions on the

    The separation, detection and quantitation of specific species contained in a sample in the field of Cultural Heritage requires selective, sensitive and reliable methods. Procedures based on liquid chromatography fulfil these requirements and offer a wide range of applicability in terms of analyte types and concentration range. The main applications of High Performance Liquid Chromatography in this field are related to the separation and detection of dyestuffs in archaeological materials and paint samples by reversed-phase liquid chromatography with suitable detectors. The relevant literature will be revised, with particular attention to sample treatment strategies and future developments. Reversed phase chromatography has also recently gained increasing importance in the analysis of lipid binders and lipid materials in archaeological residues: the main advantages and disadvantages of the new approaches will be discussed. Finally, the main applications of ion chromatography and size exclusion chromatography in the field of Cultural Heritage will be revised in this chapter. PMID:27573145

    2015-08-01

    These Many countries have put a lot of efforts, promoting education of cultural heritage, to raise the conservation awareness and increase people's participation. However, the development of Taiwan's higher education about cultural heritage has not shown a significant growth, so it didn't train talents with enough cultural heritage awareness. In the workplace, these professionals will inevitably lack of comprehensions and the appropriate professional assessments for cultural heritage. Hence, the main objective of this paper is to study and combine these concepts into the core curriculum of Department of Construction and Spatial Design at Tungnan University. It takes the local "Shenkeng historic cultural district" as a case study, and will gradually develop an proper interdisciplinary course in order to help local residents implement projects of conserving cultural heritage. This plan not only can increase schools' engagements toward communities, with an ability of social civilization, but also it can encourage the conservation and maintenance of cultural heritages.

    2009-09-01

    Local storms always had a deep impact on people communities, mainly because of the severe damage caused, because of their unpredictability and, up to a few years ago, even because of the lack of knowledge and awareness on their physical origin. Because of this large impact on real life and on imagination, people needed and wanted to describe and report the occurrence of these events, giving them suited names. Often, these nouns are related to the myth developed to explain the cause of the events. In this work, a short presentation and description of the popular nouns used to describe severe local storm events in different areas of the World is given. Countries taken into account span from Italy, moving toward Africa and reaching a few communities of Native Americans. The etymology of the names gives interesting information, useful even under the anthropological point of view, on the Culture and Believes of the peoples who adopted them. This research work is the result of an underground activity carried out in the last ten years by the authors, during their contacts with students and researchers coming from different Countries and mainly met at the International Center for Theoretical Physics in Trieste.

    Do insecurely attached individuals perceive greater rejection from their heritage culture? Few studies have examined the antecedents and outcomes of this perceived rejection – termed intragroup marginalization – in spite of its implications for the adjustment of cultural migrants to the mainstream culture. This study investigated whether anxious and avoidant attachment orientations among cultural migrants were associated with greater intragroup marginalization and, in turn, with lower subjective well-being and flourishing and higher acculturative stress. Anxious attachment was associated with heightened intragroup marginalization from friends and, in turn, with increased acculturative stress; anxious attachment was also associated with increased intragroup marginalization from family. Avoidant attachment was linked with increased intragroup marginalization from family and, in turn, with decreased subjective well-being. PMID:26839442

  2. Effective Communication with Cultural Heritage Using Virtual Technologies

    Reffat, R. M.; Nofal, E. M.

    2013-07-01

    Cultural heritage is neither static nor stable. There is a need to explore ways for effectively communicating with cultural heritage to tourists and society at large, in an age of immediacy, a time of multiple realities and to multi-cultural tourists. It is vital to consider cultural heritage as a creative and relational process where places and communities are constantly remade through creative performance. The paper introduces virtual technologies as an approach to attain effective communication with cultural heritage. This approach emphasizes the importance of "user, content and context" in guiding the production of virtual heritage, as opposed to technology being the sole motivator. It addresses how these three issues in virtual heritage need to be transformed from merely representing quantitative data towards cultural information using the proposed effective communication triangle through representing meaningful relationships between cultural heritage elements, users and context. The paper offers a focused articulation of a proposed computational platform of "interactive, personalized and contextual-based navigation" with Egyptian heritage monuments as a one step forward towards achieving effective communication with Egyptian cultural heritage.

    We discuss the evolution and state-of-the-art of the use of Building Information Modelling (BIM) in the field of culture heritage documentation. BIM is a hot theme involving different characteristics including principles, technology, even privacy rights for the cultural heritage objects. Modern documentation needs identified the potential of BIM in the recent years. Many architects, archaeologists, conservationists, engineers regard BIM as a disruptive force, changing the way professionals can document and manage a cultural heritage structure. The latest years, there are many developments in the BIM field while the developed technology and methods challenged the cultural heritage community in the documentation framework. In this review article, following a brief historic background for the BIM, we review the recent developments focusing in the cultural heritage documentation perspective.

    In archaeological studies the use of new technologies has moved into focus in the past years creating new challenges such as the processing of the massive amounts of data. In this paper we present steps and processes for smart 3D modelling of environments by use of the mobile robot Irma3D. A robot that is equipped with multiple sensors, most importantly a photo camera and a laser scanner, enables the automation of most of the processes, including data acquisition and registration. The robot was tested in two scenarios, Ostia Antica and the Würzburg Residence. The paper describes the steps for creating 3D color reconstructions of these renown cultural heritage sites.

    This contribution promotes 3D photography as an important tool to obtain objective object information. Keeping mainly in mind World Heritage documentation as well as Heritage protection, it is another intention of this paper, to stimulate the interest in applications of 3D photography for professionals as well as for amateurs. In addition this is also an activity report of the international CIPA task group 3. The main part of this paper starts with "Digging the treasure of existing international 3D photography". This does not only belong to tangible but also to intangible Cultural Heritage. 3D photography clearly supports the recording, the visualization, the preservation and the restoration of architectural and archaeological objects. Therefore the use of 3D photography in C.H. should increase on an international level. The presented samples in 3D represent a voluminous, almost partly "forgotten treasure" of international archives for 3D photography. The next chapter is on "Promoting new 3D photography in Cultural Heritage". Though 3D photographs are a well-established basic photographic and photogrammetric tool, even suited to provide "near real" documentation, they are still a matter of research and improvement. Beside the use of 3D cameras even single lenses cameras are very much suited for photographic 3D documentation purposes in Cultural Heritage. Currently at the Faculty of Civil Engineering of the University of Applied Sciences Magdeburg-Stendal, low altitude aerial photography is exposed from a maximum height of 13m, using a hand hold carbon telescope rod. The use of this "huge selfie stick" is also an (international) recommendation, to expose high resolution 3D photography of monuments under expedition conditions. In addition to the carbon rod recently a captive balloon and a hexacopter UAV- platform is in use, mainly to take better synoptically (extremely low altitude, ground truth) aerial photography.

    Sustainable development has become one of the great debates of policy-making of the XXI century. The world, is facing unprecedented change following the anthropocentrism of socio-economic growth. However, the commitment of man to ‘transmit to future generations at least the same as had' (ref) seems to be a narrowing, given extensive urban growth, population increase and climate change. However, over the last twenty years, the usage of spatial information systems have brought a positive contribution for better acknowledging the problem of environmental change, and bringing more constructive approaches to planning. Prompted by much research interest in Europe, a broad specter of biodiversity loss models, pollution and environmental degradation algorithms as well as climate change models, have become important tools under the European umbrella. Recognizing the essence of sustainable development, historico-cultural and archaeological regions have a remarkable role in the transformation of landscapes and maintenance of cultural and regional identity. Furthermore, the socio-economic, political-geographic and cultural-scientific history of the dynamics of places and localities on our earth is reflected in their historico-cultural heritage. This patrimony comprises cultural assets, such as old churches, palaces, museums, urban parks, historical architecture of cities, or landscapes of historical interest. Historico-cultural heritage also includes archaeological sites, which sometimes not only have a local value but may have a worldwide significance (e.g. Pompeii). However, massive urban growth is affecting directly the existing historico-cultural resources throughout the European region, and little attention is given to this juxtaposing reality of peri-urban growth and cultural / archaeological heritage preservation. Also, the settling patterns within historico-cultural local clusters follow a similar pattern as current growth tendencies, given the physical conditions of

    Cultural heritage sites are continuously impacted by several environmental and anthropogenic factors, including climate change, precipitation, natural hazards, wars, etc. However, there is limited data available regarding the effects of geo-hazards on cultural heritage sites. This paper presents the methodology of the PROTHEGO project, which uses radar interferometry to monitor surface deformation with mm precision to analyze the impact of geo-hazards in cultural heritage sites in Europe. PROTHEGO will provide a new, low-cost methodological approach for the safe management of cultural heritage monuments and sites located in Europe. The project will apply InSAR techniques to monitor monuments and sites that are potentially unstable due to landslides, sinkholes, settlement, subsidence, active tectonics as well as structural deformation, all of which can be effected of climate change and human interaction. The research methodology will be focused on long-term low-impact monitoring systems as well as indirect analysis of environmental contexts to investigate changes and decay of structure, material and landscape. The methodology will be applied to more than 450 sites on the UNESCO World Heritage List in geographical Europe. One of the case study selected is located in Cyprus at Choirokoitia, which is a UNESCO World Heritage site. The outcomes of PROTHEGO will support correct planning and rebalancing the contrast between endogenous (structural and materials decay, the societal development, the anthropogenic pressure) and surrounding exogenous forces (natural hazards acting on the heritage) which affecting the European cultural heritage.

    2013-04-01

    Italy is the country that owns most of the world cultural heritage as it's clear from the list of sites of inestimable value to humanity, prepared by UNESCO under the Convention concerning the protection of the world cultural and natural heritage ratified in 1972. The Italian territory is also particularly prone to natural hazards such as landslides, floods, earthquakes, volcanic eruptions, subsidence and coastal erosion which undermine the protection and preservation of cultural heritage. Aim of the present work is to provide an estimate of architectural, monumental and archaeological heritage exposed to landslide and flood risk at national scale. The input data are: the Italian Cultural Heritage database (Carta del Rischio del patrimonio culturale) realized by ISCR (Central Institute for the Conservation and Restoration); the Italian Landslide Inventory (Progetto IFFI) developed by ISPRA (Italian National Institute for Environmental Protection and Research) and the Regions and Self-Governing Provinces of Italy and the flood hazard zones defined by the Italian River Basin Authorities. Italian landslide inventory contains more than 486,000 landslides affecting an area of about 20,800 km2, equal to 6.9% of Italian territory. In order to estimate the number and type of cultural heritage at risk some GIS processing have been carried out, overlapping information from the above mentioned databases. The analysis provided the following results: Cultural Heritage exposed to landslide risk were estimated to 5.511 (6.6%) while the ones exposed to flood risk results 9.859 (11.7%). Two case studies concerning landslide phenomena affecting important Italian municipalities and the flood risk of historical centre of Rome, have been also analyzed. These results could be used to identify priorities and plan field surveys, detailed studies and monitoring systems, allowing job scheduling of cultural heritage maintenance. This need becomes more and more a necessity taking into account

    Geometric documentation is one of the most important task of the Cultural Heritage (CH) conservation and management policies. 3D documentation, prior to any conservation and restoration works, is considered a basic pre-requisite for preserving, understanding, communicating and valorizing CH sites and objects (London Charter, 2009; Sevilla Principles, 2011). 3D models have become the usual way of digitally preserving, communicating, explaining and disseminat ing cultural knowledge, as they have the capability of reproducing ancient states and behaviors. Using photo-realistic and accurate 3D models, the current conservation state can be shown and preserve for future generations. But despite the large request of 3D models in the CH field, there is no 3D documentation method which can properly satisfy all the areas with their requirements, therefore a fusion methodology (of data and sensors) is normally required and performed. The paper analyzes the fusion concept and levels as well as some merging approaches so far presented in the research community. While the paper will be necessarily incomplete due to space limitations, it will hopefully give an understanding on the actual methods of data fusion and clarify some open research issues.

  10. Culture heritage and identity - some cases in Taiwan on the protection of cultural heritage

    The protection of cultural heritage relates to an issue of identity. How a nation or a state tries to face to its history is often revealed on the protection of cultural heritage. Taiwan is as a country with complex history, especially the period after World War II. This article will work on some significant cases, regarded as ideological representation of identity. This article works on the cultural identity by observing and analyzing different cases of classified Historic Monuments. In different political periods, we see how the government tries to fabricate on the identity issue by working on Historic Monuments preservation. During the presidency of Chiang Kai-shek and his son Chiang Ching-kuo, the classification of Historic Monuments tried to focus on those make by former Chinese migrants. They tried hard to establish and reaffirm the ever existing "fact" of people in Taiwan. Whereas after the late 1980s and 1990s, after Chiang's reign, local conscience has been awaken. Political ambience turned to a new era. This freedom of speech of post-Chiang's reign encourages people to seek on their identity. The complex political situation of Taiwan makes this seeking cultural identity related to the seeking of independence of Taiwan. The respect to the aboriginal people also reoriented to include the preservation of their tribes and villages.

    Neutron Tomography (NT) investigation of Culture Heritages (CH) is an efficient tool for understanding the culture of ancient civilizations. Neutron imaging (NI) is a-state-of-the-art non-destructive tool in the area of CH and plays an important role in the modern archeology. The NI technology can be widely utilized in the field of elemental analysis. At Egypt Second Research Reactor (ETRR-2), a collimated Neutron Radiography (NR) beam is employed for neutron imaging purposes. A digital CCD camera is utilized for recording the beam attenuation in the sample. This helps for the detection of hidden objects and characterization of material properties. Research activity can be extended to use computer software for quantitative neutron measurement. Development of image processing algorithms can be used to obtain high quality images. In this work, full description of ETRR-2 was introduced with up to date neutron imaging system as well. Tomographic investigation of a clay forged artifact represents CH object was studied by neutron imaging methods in order to obtain some hidden information and highlight some attractive quantitative measurements. Computer software was used for imaging processing and enhancement. Also the Astra Image 3.0 Pro software was employed for high precise measurements and imaging enhancement using advanced algorithms. This work increased the effective utilization of the ETRR-2 Neutron Radiography/Tomography (NR/T) technique in Culture Heritages activities. PMID:24374405

    Cultural Heritage is known as an invaluable asset of human being, which portrays his achievements over centuries. The need for identification and preservation of cultural heritage is well understood and experts' attempt is to exploit any possible method to fulfill this aim. There are several published literatures and documents, which emphasize on the importance of the documentation of the cultural heritage such as Burra Charter. However, with the development of human and invention of new tools and technologies, the concept of the conservation of cultural heritage has changed considerably. The new technologies such as computers and digital tools have opened new windows and bestowed new opportunities in the process of conservation of cultural heritage. In this regard, it is important to review different technologies in order to make the best advantage of these tools in the cultural heritage field. The focus of this paper would be on the non-technical users who need to gain an overall comprehension of these new emerging tools. The foundation of this paper will be on the existing literatures published by various experts in addition to the author's experience and research in the conservation field.

    All stakeholders in cultural heritage share an interest in fabrication methods and material technology. Until now methods for analysis of organic materials, particularly proteins, have not been widely available to researchers at cultural institutions. This paper will describe an analytical method for the identification of collagen-based materials from soft tissue sources and show examples of its application to diverse museum objects. The method, peptide mass fingerprinting (PMF), uses enzymatic digestion of extracted proteins to produce a mixture of peptides. The mass spectrum of the mixture contains characteristic marker ions-a peptide mass fingerprint-which are compared to species-specific markers from references as the basis of identification. Preliminary results indicate that analysis of materials from aged samples, several different tissue types, and tanned or untanned materials yields comparable PMF results. Significantly, PMF is simple, rapid, sensitive and specific, has been implemented in a museum laboratory, and is being practiced successfully by non-specialists. PMID:23807214

  14. Globalization and Localization of Heritage Preservation in Taiwan - an Analysis Perspective under the Cultural Heritage Preservation Act

    2015-08-01

    The key contribution to the legislation of heritage preservation in Taiwan primarily derived from the historical monument movements in the 1970s. Specific legislation results include the establishment of Council for Cultural Affairs and the implementation of the Cultural Heritage Preservation Act in 1982. Although the Cultural Heritage Preservation Act is the first subjective cultural act, its lack of structure during the initial commencement stages made it un-conducive to heritage preservation and thus unable to meet the people's expectations. Therefore, throughout the 33 years after the implementation of the Cultural Heritage Preservation Act, the Act has been amended 6 times. These amendments reflect the degree of importance that the society has attached to heritage preservation, and the innovative system also showcases the progress in preservation concepts and methods. These innovative orientations, such as emphasizing on the authenticity and integrity of heritage preservation, intangible cultural heritage, and cultural diversity, conform to the international preservation trends. They are also local trends such as encouraging community participation, adaptive-reuse, or enhancing the local governments' powers to implement local cultural governance. This is particularly true for the fifth comprehensive revision in 2005, which has symbolic significance because its contents epitomized the heritage preservation work while moving Taiwan's heritage preservation system towards globalization and localization. Therefore, we analyzed the Cultural Heritage Preservation Act amendment and revision processes over the past 33 years to highlight the innovations in Taiwan's cultural heritage work and illustrate their globalization and localization features. Finally, we proposed recommendations for Taiwan's preservation work in the future as the Cultural Heritage Preservation Act is about to undergo its seventh amendment in 2015.

    is little "aggressive" to the surface of installation, has been identified as a solution to minimize the electrode resistance; this topic is significant, since classical georesistivimeters, such as the one here used, provide a resistance of 10 KOhm. Finally, the prototype was designed and built by means of a multi-electrode cable formed by 48 Ag/AgCl electrodes 1m spaced, which is particularly suitable for the high spatial resolution and shallower layers inspection of interest Cultural Heritage purposes. Few preliminary tests have been performed on different construction samples and the results were well evaluated with respect to their "interpretability", also thanks to the use of an inversion stage carried out by using the Res2DInv software(Loke and Baker, 1996). The system was effective in few situations and relatively inexpensive to be upgraded for tasks not originally conceived for this system. Anyway, several "applicative" problems have to be solved as well as the electrode positioning on not-horizontal surfaces, the effect of electro-conductive gel on precious materials surfaces and the effect of the current injection on electrode response quality.

    2015-08-01

    Recent dramatic events have brought to the forefront the debate on how to protect, safeguard and document Cultural Heritage in conflict areas. Heritage places have become battlefields, sources of illicit trafficking and even deliberate targets of destruction because of the politicisation to further conflict ideologies as well as misinterpretation of the values they represent. Is it possible to protect Cultural Heritage under such circumstances? If yes, when is the right time to intervene and who can help in this task? How can documentation and training assist? The International Course on First Aid to Cultural Heritage in Times of Crisis promoted by ICCROM (The International Centre for the Study of the Preservation and Restoration of Cultural Property) in collaboration with various partners focuses specifically on ways to help in such difficult and stressful situations. This paper explores the methodological approach and highlights the special circumstances that surround rapid documentation and preliminary condition assessment in conflict areas, and in cases of complex emergencies such as an earthquake striking a conflict area. The paper identifies international actors that might play a special and crucial role in the first steps of such a situation and recognizes the need for training activities to strengthen capacities for disaster response to cultural heritage at national and regional levels.

    2007-07-01

    This is an introductory paper of a recent EC project dealing with research in cultural heritage and aiming to communicate new fields of application for optical metrology techniques. The project is in its initial state and more conclusive information is expected to be available at the time of the perspective conference. Nowadays safety, ethical, economical and security issues as well as the increase demand for loaning of art objects for exhibitions in transit, are forcing the Conservation Community to undertake strong initiatives and actions against various types of mistreatment, damage or fraud, during transportation of movable Cultural Heritage. Therefore the interest directs to the development of innovative methodologies and instrumentation to respond to critical aspects of increased importance in cultural heritage preservation, among which of prior consideration are: to secure proper treatment, assess probable damage, fight fraud actions in transportation.

  5. Analysis of Cultural Heritage by Accelerator Techniques and Analytical Imaging

    Ide-Ektessabi, Ari; Toque, Jay Arre; Murayama, Yusuke

    2011-12-01

    In this paper we present the result of experimental investigation using two very important accelerator techniques: (1) synchrotron radiation XRF and XAFS; and (2) accelerator mass spectrometry and multispectral analytical imaging for the investigation of cultural heritage. We also want to introduce a complementary approach to the investigation of artworks which is noninvasive and nondestructive that can be applied in situ. Four major projects will be discussed to illustrate the potential applications of these accelerator and analytical imaging techniques: (1) investigation of Mongolian Textile (Genghis Khan and Kublai Khan Period) using XRF, AMS and electron microscopy; (2) XRF studies of pigments collected from Korean Buddhist paintings; (3) creating a database of elemental composition and spectral reflectance of more than 1000 Japanese pigments which have been used for traditional Japanese paintings; and (4) visible light-near infrared spectroscopy and multispectral imaging of degraded malachite and azurite. The XRF measurements of the Japanese and Korean pigments could be used to complement the results of pigment identification by analytical imaging through spectral reflectance reconstruction. On the other hand, analysis of the Mongolian textiles revealed that they were produced between 12th and 13th century. Elemental analysis of the samples showed that they contained traces of gold, copper, iron and titanium. Based on the age and trace elements in the samples, it was concluded that the textiles were produced during the height of power of the Mongol empire, which makes them a valuable cultural heritage. Finally, the analysis of the degraded and discolored malachite and azurite demonstrates how multispectral analytical imaging could be used to complement the results of high energy-based techniques.

    2014-01-01

    In recent years nuclear magnetic resonance (NMR) sensors have been increasingly applied to investigate, characterize and monitor objects of cultural heritage interest. NMR is not confined to a few specific applications, but rather its use can be successfully extended to a wide number of different cultural heritage issues. A breakthrough has surely been the recent development of portable NMR sensors which can be applied in situ for non-destructive and non-invasive investigations. In this paper three studies illustrating the potential of NMR sensors in this field of research are reported. PMID:24755519

    The intentional damages to local Cultural Heritage sites carried out in recent months by the Islamic State (IS) have received wide coverage from the media worldwide. Earth Observation data is an important tool to assess these damages in such non-accessible areas: If a fast response is desired, automated image processing techniques would be needed to speed up the analysis. This paper shows the first results of applying fast and robust change detection techniques to sensitive areas. A map highlighting potentially damaged buildings is derived, which could help experts at timely assessing the damages to the Cultural Heritage sites in the observed images.

    Respaldiza, A.; Wachowicz, M.; Vázquez Hoehne, A.

    2012-06-01

    Cultural heritage is a complex and diverse concept, which brings together a wide domain of information. Resources linked to a cultural heritage site may consist of physical artefacts, books, works of art, pictures, historical maps, aerial photographs, archaeological surveys and 3D models. Moreover, all these resources are listed and described by a set of a variety of metadata specifications that allow their online search and consultation on the most basic characteristics of them. Some examples include Norma ISO 19115, Dublin Core, AAT, CDWA, CCO, DACS, MARC, MoReq, MODS, MuseumDat, TGN, SPECTRUM, VRA Core and Z39.50. Gateways are in place to fit in these metadata standards into those used in a SDI (ISO 19115 or INSPIRE), but substantial work still remains to be done for the complete incorporation of cultural heritage information. Therefore, the aim of this paper is to demonstrate how the complexity of cultural heritage resources can be dealt with by a visual exploration of their metadata within a 3D collaborative environment. The 3D collaborative environments are promising tools that represent the new frontier of our capacity of learning, understanding, communicating and transmitting culture.

    2013-06-01

    The aim of this paper is provide an overview of the capacity building programmes in maritime and underwater cultural heritage (MUCH) conducted by the authors in Tanzania and Mozambique. Tanzania and Mozambique have long histories of indigenous cultures, foreign contacts and influences and African adaptations beginning in the late Greco-Roman period, when the coastal populations exploited the peoples and riches of the interior. Today the coastline contains numerous examples of indigenous tangible and intangible heritage and many sites and histories related to the Swahili culture. Some exploratory research and training has been conducted in Tanzania and Mozambique, but the implementation by local residents of their own MUCH programme is still at an early stage. Under a UNESCO agreement framework, Tanzania in particular has started to develop a MUCH programme, which can assist in highlighting their extensive histories, cultural landscapes and cultural identity.

  15. Management Documentation: Indicators & Good Practice at Cultural Heritage Places

    NASA Astrophysics Data System (ADS)

    Eppich, R.; Garcia Grinda, J. L.

    2015-08-01

    Documentation for cultural heritage places usually refers to describing the physical attributes, surrounding context, condition or environment; most of the time with images, graphics, maps or digital 3D models in their various forms with supporting textural information. Just as important as this type of information is the documentation of managerial attributes. How do managers of cultural heritage places collect information related to financial or economic well-being? How are data collected over time measured, and what are significant indicators for improvement? What quality of indicator is good enough? Good management of cultural heritage places is essential for conservation longevity, preservation of values and enjoyment by the public. But how is management documented? The paper will describe the research methodology, selection and description of attributes or indicators related to good management practice. It will describe the criteria for indicator selection and why they are important, how and when they are collected, by whom, and the difficulties in obtaining this information. As importantly it will describe how this type of documentation directly contributes to improving conservation practice. Good practice summaries will be presented that highlight this type of documentation including Pamplona and Ávila, Spain and Valletta, Malta. Conclusions are drawn with preliminary recommendations for improvement of this important aspect of documentation. Documentation of this nature is not typical and presents a unique challenge to collect, measure and communicate easily. However, it is an essential category that is often ignored yet absolutely essential in order to conserve cultural heritage places.

    At present, where 3D modeling and visualisation in cultural heritage are concerned, an object's documentation lacks its interconnected memory provided by multidisciplinary examination and linked data. As the layers of paint, wood, and brick recount a structure's physical properties, the intangible, such as the forms of worship through song, dance, burning incense, and oral traditions, contributes to the greater story of its cultural heritage import. Furthermore, as an object or structure evolves through time, external political, religious, or environmental forces can affect it as well. As tangible and intangible entities associated with the structure transform, its narrative becomes dynamic and difficult to easily record. The Initial Training Network for Digital Cultural Heritage (ITN-DCH), a Marie Curie Actions project under the EU 7th Framework Programme, seeks to challenge this complexity by developing a novel methodology capable of offering such a holistic framework. With the integration of digitisation, conservation, linked data, and retrieval systems for DCH, the nature of investigation and dissemination will be augmented significantly. Examples of utilisating and evaluating this framework will range from a UNESCOWorld Heritage site, the Byzantine church of Panagia Forviotissa Asinou in the Troodos Mountains of Cyprus, to various religious icons and a monument located at the Monastery of Saint Neophytos. The application of this effort to the Asinou church, representing the first case study of the ITN-DCH project, is used as a template example in order to assess the technical challenges involved in the creation of such a framework.

  18. FOREWORD: Cultural heritage and civil engineering Cultural heritage and civil engineering

    Masini, Nicola; Soldovieri, Francesco; Alvarez de Buergo, Monica; Dumoulin, Jean

    2012-08-01

    This special issue of Journal of Geophysics and Engineering offers a diverse panorama of approaches and technologies that aim to characterize and analyse the state of conservation and health of cultural heritage and civil infrastructure. In particular, it provides a significant overview not only of the effectiveness but also of the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques. The choice of diagnostic strategy depends on the material (concrete, masonry), the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment, etc). The paper by Fornaro et al reports an important technological advance in the field of slow deformation monitoring of civil infrastructure by means of differential interferometric synthetic aperture radar (SAR) from satellite platforms. The paper shows how the joint exploitation of the last generation of X-band SAR sensors, such as TerraSAR-X, and novel tomographic approaches makes possible advanced multi-dimensional imaging of real structures such as the Las Vegas Monorail. Within the same SAR-based applications, Tapete et al tested the capability of persistent scatterer interferometry (PSI) techniques in the preventative diagnosis of deformation threatening the structural stability of archaeological monuments and buried structures in the Roman Forum, Palatino Hill and Oppio Hill in the centre of Rome. A PSInSAR processing approach, based on the use of the SqueeSAR algorithm, has been shown to be highly suitable for retrieving not only information about displacements of the archaeological remains, but also evidence of criticalities affecting partially or totally buried structures, such as those discovered at Nero's Golden

    The Library of Congress' Preservation Research and Testing Division has established an advanced preservation studies scientific program for research and analysis of the diverse range of cultural heritage objects in its collection. Using this system, the Library is currently developing specialized integrated research methodologies for extending preservation analytical capacities through non-destructive hyperspectral imaging of cultural objects. The research program has revealed key information to support preservation specialists, scholars and other institutions. The approach requires close and ongoing collaboration between a range of scientific and cultural heritage personnel - imaging and preservation scientists, art historians, curators, conservators and technology analysts. A research project of the Pierre L'Enfant Plan of Washington DC, 1791 had been undertaken to implement and advance the image analysis capabilities of the imaging system. Innovative imaging options and analysis techniques allow greater processing and analysis capacities to establish the imaging technique as the first initial non-invasive analysis and documentation step in all cultural heritage analyses. Mapping spectral responses, organic and inorganic data, topography semi-microscopic imaging, and creating full spectrum images have greatly extended this capacity from a simple image capture technique. Linking hyperspectral data with other non-destructive analyses has further enhanced the research potential of this image analysis technique.

    In recent years the Earth Sciences community is facing the need to achieve a more effective and efficient dissemination of its scientific culture. There is now a growing needing to integrate the use of "traditional" dissemination media of cultural heritage with the new digital technologies. Getting people involved in geoheritage site's activities represents a crucial issue in order to better communicate and increase the collective awareness of natural hazards, risk, and environmental change. The Reale Osservatorio Vesuviano (ROV) which is part of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), owns collections unique in their combination of scientific, historical and artistic importance. The long history of ROV is extensively documented in its collections. This heritage - of great scientific and cultural value and unique for its abundance and variety - tells the story of the first observatory in the world, closely linked to the activity of Vesuvius, and the commitment of many scientists who dedicated their lives to study the volcano. The collections include: a) old books on volcanological matters, b) collection of rocks, minerals, volcanic ash and other materials from historical eruptions of Vesuvius, c) recordings on smoked paper of Vesuvius seismic activity from 1915 until 1970, d) scientific instruments, e) geological and geomorphological maps and models, f) vintage photographs and filmed sequences of eruptions, g) gouaches of Vesuvius and h) lava medals. The exposition of these collections, improved with the new digital contents, may trace new and unexplored routes for the dissemination of Earth Sciences related culture. The ethical duty of the ROV is the creation of an universal identity by taking a picture of the evolution of the society through the training of the culture of seismic and volcanic risk. A disappearance of its heritage could represent an huge impoverishment of its community: the ROV carries in fact the cultural identity of the

    This special issue of Journal of Geophysics and Engineering offers a diverse panorama of approaches and technologies that aim to characterize and analyse the state of conservation and health of cultural heritage and civil infrastructure. In particular, it provides a significant overview not only of the effectiveness but also of the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques. The choice of diagnostic strategy depends on the material (concrete, masonry), the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment, etc). The paper by Fornaro et al reports an important technological advance in the field of slow deformation monitoring of civil infrastructure by means of differential interferometric synthetic aperture radar (SAR) from satellite platforms. The paper shows how the joint exploitation of the last generation of X-band SAR sensors, such as TerraSAR-X, and novel tomographic approaches makes possible advanced multi-dimensional imaging of real structures such as the Las Vegas Monorail. Within the same SAR-based applications, Tapete et al tested the capability of persistent scatterer interferometry (PSI) techniques in the preventative diagnosis of deformation threatening the structural stability of archaeological monuments and buried structures in the Roman Forum, Palatino Hill and Oppio Hill in the centre of Rome. A PSInSAR processing approach, based on the use of the SqueeSAR algorithm, has been shown to be highly suitable for retrieving not only information about displacements of the archaeological remains, but also evidence of criticalities affecting partially or totally buried structures, such as those discovered at Nero's Golden

    2014-08-01

    Ion beam analysis (IBA) techniques play an important role in the field of cultural heritage. IBA was one of the first physical methods applied to archaeology in the 70s. 40 years later, more than 25 accelerator laboratories were or are involved in cultural heritage applications. The advantages of the IBA techniques match very well the requirements for the analysis of archaeological or museum objects: non destructiveness, major, minor and trace element analysis, information in depth, elemental mapping… Thanks to this collected information, IBA techniques can answer archaeological and conservation questions: provenance determination, ancient technologies (fabrication, transformation, recipes…) and conservation issues. In spite of the competition with portable devices and large facilities (such as synchrotron or neutron reactors), the IBA methods keep their interest due to the possibility of associating two or three of them according to the archaeological or art issue. In this article, some examples chosen for their original approach are presented: PIXE for X-radiography, provenance of prehistoric pigments and painting characterisation. They illustrate the useful versatility of IBA for cultural heritage studies. Perspectives for further improvements are also proposed.

    The Austrian Society for surveying and Geoinformation (ASG) has proposed to submit "Boundaries and Boundary Marks" for the UNESCO World Heritage title. It was time that boundaries, borders and limits of all types as well as ownership rights would find the proper attention in the global public. Landmarks symbolize the real property and the associated rights and obligations, in a figurative sense, the property generally and all legal limits. A democratic state of law is impossible at today's population density without a functioning land administration system with surveying and jurisdiction. As monumental World Heritage representatives of the geodetic artwork "Boundaries and Boundary Marks" are specifically proposed: remaining monuments of the original cadastral geodetic network, the first pan-Austrian surveying headquarters in Vienna, and a specific selection of outstanding boundary monuments. Landmarks are monuments to the boundaries which separate rights and obligations, but also connect the neighbors peacefully after written agreement. "And cursed be he who does not respect the boundaries" you wrote already 3000 years ago. Boundaries and Boundary Marks are a real thing; they all belong to the tangible or material heritage of human history. In this context also the intangible heritage is discussed. This refers to oral tradition and expressions, performing arts; social practices, rituals and festive events; as well as to knowledge and practices handling nature and the universe. "Boundaries and Boundary Marks" do not belong to it, but clearly to the material cultural world heritage. "Boundary and Boundary Marks" is proposed to be listed according to the criteria (ii),(iv),(vi).

    Past restorations performed with acrylic and vinyl polymers showed detrimental effects to wall paintings that lead to the complete disfiguration of the painted surfaces. The removal of these materials performed with the traditional solvent-based methodology represents a real challenge to conservators and usually achieves very poor results. This review reports on the new palette, nowadays available to restorers, based on microemulsions, micellar systems, physical and chemical gels specifically formulated for the cleaning of cultural heritage artefacts. These systems have been developed in the last twenty years within the cultural framework of colloids and surface science. PMID:24200088

    The Monuments Board of the Slovak Republic within the Operational Programme Information Society from 2012, is digital documenting selected national cultural monuments of the Slovak Republic. Within this project 1,855 architectural objects in Slovakia has been digitized by internal component of the The Monuments Board SR and external suppliers. For measurement there were used the most modern surveying technologies - digital photogrammetry (DP) of land and aerial images and terrestrial laser scanning (TLS). The outputs of digitization are point cloud, highly detailed polygon models, orthoimages, gigapixel images and 2D drawing documentations. During the project, arose the need to process the huge number of images (thousands or tens of thousands) and also need a TLS connection to DP. For this reason, started Slovak commercial firm developing of new software which enable this processing and connection. The outcomes are unique spatial models of large architectural complexes (castles, monasteries, churches...) with high detail and accuracy up to 1 cm. Article is devoted to the project description and the method of digitization for the specific types of the cultural monuments.

    The development of contactless documentation techniques is allowing researchers to collect high volumes of three-dimensional data in a short time but with high levels of accuracy. The digitalisation of cultural heritage opens up the possibility of using image processing and analysis, and computer graphics techniques, to preserve this heritage for future generations; augmenting it with additional information or with new possibilities for its enjoyment and use. The collection of precise datasets about cultural heritage status is crucial for its interpretation, its conservation and during the restoration processes. The application of digital-imaging solutions for various feature extraction, image data-analysis techniques, and three-dimensional reconstruction of ancient artworks, allows the creation of multidimensional models that can incorporate information coming from heterogeneous data sets, research results and historical sources. Real objects can be scanned and reconstructed virtually, with high levels of data accuracy and resolution. Real-time visualisation software and hardware is rapidly evolving and complex three-dimensional models can be interactively visualised and explored on applications developed for mobile devices. This paper will show how a 3D reconstruction of an object, with multiple layers of information, can be stored and visualised through a mobile application that will allow interaction with a physical object for its study and analysis, using 3D Tracking based Augmented Reality techniques.

    Despite the wide application of surface plasmon resonance (SPR) to a broad area of interests, from environment to food analysis, from drug discovery to diagnostics, its exploitation in cultural heritage conservation is still unexplored. Water-based highly viscous polymeric dispersions (HVPD) composed by partially hydrolyzed polyvinyl acetate (PVA), borax, and water, were recently developed and successfully applied for the selective removal of surface degradation patinas (i.e. protein materials, natural resins etc.) from paintings of historical and artistic interest. This approach is here coupled for the first time to a SPR biosensor to simultaneously recognize albumen, yolk, or their mixtures in HVPD extracts. Ovalbumin and immunoglobulin Y are selected as analytes for egg white and yolk recognition, respectively. The biosensor was first characterized on standard analytes within the range 0-400mgL(-1) and then on fresh and dried egg albumen and yolk down to 2·10(^4) and 1·10(^5) dilution factors, respectively. Once optimized, the biosensor was combined to the HVPD application on simulated and real art samples for the evaluation of hen egg presence in the extract, i.e. albumen, yolk, or their co-presence in the matrix. For a contemporary 'sacred icon', realized by the traditional egg tempera procedure described by Cennino Cennini, the biosensor successfully distinguished different uses of egg components for the realization of painted and gilded areas, i.e. yolk and albumen, respectively. Finally, a XVIII century italian painting whose the realization technique is unknown, was tested confirming its egg tempera-based realization technique. PMID:27155120

    Scharf, Peter M.; Hyman, Malcolm

    This chapter is about enhancing access to primary cultural heritage materials of India housed in academic libraries by integrating them with machine-readable texts, lexical resources, and linguistic software in a digital library. Integrating primary cultural materials with a digital library can enable broad use of Indic collections for research and education. For the purposes of illustrating this procedure, we outline here the development of a prototype using the collections of Sanskrit manuscripts in the libraries at Brown University and the University of Pennsylvania and integrating them with The Sanskrit Library. The result is extendable to collections of Indic materials throughout the world and can serve as a model for digitization projects of cultural materials in other major culture-bearing languages such as Greek, Latin, Arabic, Persian, and Chinese.

    For three decades, ion beam analysis (IBA) in external mode was considered as the best choice for the characterisation of cultural heritage materials, as it combines excellent analytical performance and non-invasive character. However, in recent years, other analytical techniques arose as serious competitors, such as those based on synchrotron radiation (X-ray absorption, fluorescence or diffraction) or those using portable instruments (XRF, micro-Raman). It is shown that nevertheless IBA remains unmatched thanks to two unique features, namely the analysis of light elements and the high-resolution 3D chemical imaging.

    The diagnostic investigations are an important resource in the studies on Cultural Heritage to enhance the knowledge on execution techniques, materials and conservation status of a work of art. In this field, due to the great historical and artistic value of the objects, preservation is the main concern; for this reason, new technological equipment has been designed and developed in the Physics Departments of the Universities of Ferrara and Bologna to enhance the non-invasive approach to the study of pictorial artworks and other objects of cultural interest. Infrared (IR) reflectography, X-ray radiography and computed tomography (CT), applied to works of art, are joined by the same goal: to get hidden information on execution techniques and inner structure pursuing the non-invasiveness of the methods, although using different setup and physical principles. In this work transportable imaging systems to investigate large objects in museums and galleries are presented. In particular, 2D scanning devices for IR reflectography and X-ray radiography, CT systems and some applications to the Cultural Heritage are described.

    The field of Cultural Heritage has inspired, in the course of last few years, an interest more and more important on behalf of scientific community that deals to survey. The idea that knowledge of a site doesn't apply only to its history but must necessarily include its characteristics of position, shape and geometry, is gathering pace. In Geomatic science the field of cultural heritage benefits to an integrated approach of techniques and different technologies. Every cultural site in fact, is a case in itself, with its own characteristics, problems and specificness. Current techniques offer opportunity to achieve new ways of representation and visualization of cultural site, with the aim of a better metric description. This techniques are powerful tools for analysis of sites and supports to activity of reconstruction and repair. Biggest expectations in this field is laser three-dimensional scanning technique; a system which is able to operate in a methodical way in speed of acquisition and in possibility to access data in real time. Documentation and filing of state of a monument or site is essential in case of reconstruction or conservative project. Possibility to detect very complex geometries with great accuracy allows an in depth study of constructive techniques, making analysis of geometrical details easier which is, with traditional techniques, difficult to achieve. Biggest problems about use of laser scanner survey are graphic outputs for restorers and architects, in fact they often don't know real potential of this techniques, methodologies and functionalities and they expect traditional outputs such as floor plans, cross sections and front elevation of cultural asset. Present study is focused on finding a workflow to support activity of study, restoration and conservative project of cultural heritage, extracting automatically (or with a limited manual operation) graphic outputs from laser scanner survey. Some procedure was tested on two case study the

    The international debate on the issue of human remains in museums and on the ethical issues related to their exhibition stimulates reflection on the Italian anatomical collections and on their preparations. A definition of human remains or of anatomical preparation does not exist in the Italian legislation. The anatomical specimens in museums are protected by the laws of Cultural Heritage as part of public collections, but their status is not well defined. By their nature of human material they would in fact be considered as a special category of Cultural Heritage. Because they are part of a cadaver they can be regarded as res nullius, but since treated with special techniques they could also change their meaning and being considered a species nova. Finally, it reflects on the possibility of creating a museum in Italy composed by new anatomical preparations. The article outline the contours of a museological issue that deserves to be investigated in order to better identify the anatomical preparations and their management in museums. PMID:26946604

    Most of the Cultural Heritage built in NW Iberian Peninsula is made of granite which exposition to the environment leads to the formation of deposits and coatings, mainly two types: biological colonization and sulphated black crusts. Nowadays, another form of alteration derives from graffiti paints when these are applied as an act of vandalism. A deep revision needs to be addressed considering the severity of these deterioration forms on granite and the different cleaning effectiveness achieved by cleaning procedures used to remove them. The scientific literature about these topics on granite is scarcer than on sedimentary carbonate stones and marbles, but the importance of the granite in NW Iberian Peninsula Cultural Heritage claims this review centred on biological colonization, sulphated black crusts and graffiti on granite and their effectiveness of the common cleaning procedures. Furthermore, this paper carried out a review of the knowledge about those three alteration forms on granite, as well as bringing together all the major studies in the field of the granite cleaning with traditional procedures (chemical and mechanical) and with the recent developed technique based on the laser ablation. Findings concerning the effectiveness evaluation of these cleaning procedures, considering the coating extraction ability and the damage induced on the granite surface, are described. Finally, some futures research lines are pointed out. PMID:27443454

    The neutron and gamma imaging facility placed at the tangential channel of the TRIGA-ACPR from INR was used for tomography investigations on a test object with good results and shortly followed its involvement for tomography investigations on prehistoric statues of clay from the Arges County Museum. This activity was performed in connection with a research contract with IAEA with title "The neutron and gamma imaging method combined with neutron-based analytical methods for cultural heritage research", in the frame of a current CRP, that helps curators to reveal the internal structure and composition of the objects. The detector system has been developed based on two interchangeable scintillators, one for thermal neutrons and the other one for gamma radiations, a mirror of float glass coated with aluminum and two interchangeable CCD cameras. Experiments of tomography imaging for two prehistoric statues of clay with CCD STARLIGHT XPRESS SXV-H9 camera with XD-4 type image intensifier are presented in this paper. The tomography reconstructions with Octopus software have shown the potential of good results even for 100 projections/1800. This was a good opportunity for the dissemination of the investigation methods based on neutrons for cultural heritage and beyond this area.

    The digitization of both volumetric and flat objects is the nowadays-preferred method in order to preserve cultural heritage items. High quality digital files obtained from photographic plates, films and prints, paintings, drawings, gravures, fabrics and sculptures, allows not only for a wider diffusion and on line transmission, but also for the preservation of the original items from future handling. Early digitization procedures used scanners for flat opaque or translucent objects and camera only for volumetric or flat highly texturized materials. The technical obsolescence of the high-end scanners and the improvement achieved by professional cameras has result in a wide use of cameras with digital back to digitize any kind of cultural heritage item. Since the lens, the digital back, the software controlling the camera and the digital image processing provide a wide range of possibilities, there is necessary to standardize the methods used in the reproduction work leading to preserve as high as possible the original item properties. This work presents an overview about methods used for camera system characterization, as well as the best procedures in order to identify and counteract the effect of the lens residual aberrations, sensor aliasing, image illumination, color management and image optimization by means of parametric image processing. As a corollary, the work shows some examples of reproduction workflow applied to the digitization of valuable art pieces and glass plate photographic black and white negatives.

  4. Conservation of stone built cultural heritage and preservation of memories

    2016-04-01

    Certainly, the main justification for the conservation of cultural heritage built, lies in the meanings that these buildings have, either to the history of nations, either as part of the cultural heritage of humanity. On the other hand, and taking into account the use of stone, it can be said that in addition to cultural and aesthetic values usually associated with these monuments or architectural ensembles that make up this heritage, the presence of stone materials gives another dimension to those constructions, which is the geo-memory. This means that, due to the presence of this material, where each has its own history, it is also possible to identify geo-memories for each of these monuments or architectural ensembles that make up this heritage, either the genesis point of view, involving environments and processes, either regarding the formation ages of these materials. At the same time and due to the use of these materials can be said that each monument or group of monuments is a reflection of the geo-diversity of a determined region or territory. In Brazil, due to its large territory, this geo-diversity includes a wide range of geological environments, phenomena and processes, giving rise to diverse stone materials, which can be observed in the monuments that are part of your built heritage. Thus in old buildings of historic sites located in particular in the southern and southeastern regions of Brazil, this geo-diversity is present because many types of rocks were used, igneous, metamorphic or sedimentary compositions and of very different ages. Of these types stands out, for example, granites and gneisses, which were used in the states of Rio de Janeiro and Minas Gerais, where they are very common. In such cases, the rocks were formed, or end of the Paleoproterozoic, or at the end of the Neoproterozoic and have different textures, sometimes with predominance of biotite, among mica, sometimes amphibole, as hornblende, or with garnet. They were often used in

    Serial transnational World Heritage nominations are challenging the way cultural heritage has been managed and evaluated in the past. Serial transnational World Heritage nominations are unique in that they consist of multiple sites listed as one property, distributed in different countries, involving a large diversity of stakeholders in the process. As a result, there is a need for precise baseline information for monitoring, reporting and decision making. This type of nomination requires different methodologies and tools to improve the monitoring cycle from the beginning of the nomination towards the periodic reporting. The case study of the Silk Roads Cultural Heritage Resource Information System (CHRIS) illustrates the use of a Geographical Content Management System (Geo-CMS) supporting the serial transnational World Heritage nomination and the monitoring of the Silk Roads in the five Central Asian countries. The Silk Roads CHRIS is an initiative supported by UNESCO World Heritage Centre (WHC) and the Belgian Federal Science Policy Office (BELSPO), and developed by a consortium headed by the Raymond Lemaire International Centre for Conservation (RLICC) at the KULeuven. The Silk Roads CHRIS has been successfully assisting in the preparation of the nomination dossiers of the Republics of Kazakhstan, Tajikistan and Uzbekistan and will be used as a tool for monitoring tool in the Central Asian countries.

    Photonic technologies play a leading innovative role of research in the fields of Cultural Heritage (CH) conservation, preservation and digitisation. In particular photonic technologies have introduced a new indispensable era of research in the conservation of cultural artefacts expanding from decorative objects, paintings, sculptures, monuments to archaeological sites and including fields of application as diverse as materials characterisation to restoration practices and from defect topography to 3d artwork reconstruction. Thus the last two decades photonic technologies have emerged as unique answer or most competitive alternative into many long-term standing disputes in conservation and restoration of Cultural Heritage. Despite the impressive advances on the state-of-the-art ranging from custom-made system development to new methods and practises, photonic research and technological developments remain incoherently scattered and fragmented with a significant amount of duplication of work and misuse of resources. In this context, further progress should aim to capitalise on the so far achieved milestones in any of the diverse applications flourished in the field of CH. Embedding of experimental facilities and conclusions seems the only way to secure the progress beyond the existing state of the art and its false use. The solution to this embedment seems possible through the new computing environments. Cloud computing environment and remote laboratory access hold the missing research objective to bring the leading research together and integrate the achievements. The cloud environment would allow experts from museums, galleries, historical sites, art historians, conservators, scientists and technologists, conservation and technical laboratories and SMEs to interact their research, communicate their achievements and share data and resources. The main instrument of this integration is the creation of a common research platform termed here Virtual Laboratory allowing

    The relevance of the information produced by science and technology for the knowledge of the cultural heritage depends on the quality of the feedback and, consequently, on the "cultural" distance between scientists and end-users. In particular, the solution to this problem mainly resides in the capability of end-users' capability to assess and transform the knowledge produced by diagnostics with regard to: information on both cultural objects and sites (decay patterns, vulnerability, presence of buried archaeological remains); decision making (management plan, conservation project, and excavation plan). From our experience in the field of the cultural heritage and namely the conservation, of monuments, there is a significant gap of information between technologists (geophysicists/physicists/engineers) and end-users (conservators/historians/architects). This cultural gap is due to the difficulty to interpret "indirect data" produced by non invasive diagnostics (i.e. radargrams/thermal images/seismic tomography etc..) in order to provide information useful to improve the historical knowledge (e.g. the chronology of the different phases of a building), to characterise the state of conservation (e.g. detection of cracks in the masonry) and to monitor in time cultural heritage artifacts and sites. The possible answer to this difficulty is in the set-up of a knowledge chain regarding the following steps: - Integrated application of novel and robust data processing methods; - Augmented reality as a tool for making easier the interpretation of non invasive - investigations for the analysis of decay pathologies of masonry and architectural surfaces; - The comparison between direct data (carrots, visual inspection) and results from non-invasive tests, including geophysics, aims to improve the interpretation and the rendering of the monuments and even of the archaeological landscapes; - The use of specimens or test beds for the detection of archaeological features and

    The international development of the underwater archaeology and underwater cultural heritage (UCH) management disciplines has witnessed a progressive buildup of the disciplinary debate. From an initial methodological focus, still active and necessary, the two interconnected disciplines have moved toward topics and aspects external, but complementary, to the disciplines themselves which are tied together in mutual exchange. Legal, economic, social, cultural (stricto sensu), and psychological aspects all find their expression in strategies quintessential, especially, to the management of UCH. The discipline's socio-cultural wherewithal has been internationally recognized, analyzed, evaluated, and exploited in the planning of activities directed toward UCH management. In Italy, however, a lack of a coherent planning has emerged which does not take into account the various aspects composing a productive program for the management of UCH, both at the regional and national levels. Considering the issue in Italy, this contribution will offer an overview of the Sardinian perspective, offering some considerations toward envisaging an achievable, structured program for the management of underwater cultural resources within a specific regional panorama.

  19. Diachronic 3d Reconstruction for Lost Cultural Heritage

    2011-09-01

    Cultural Heritage artifacts can often be underestimated for their hidden presence in the landscape. Such problem is particularly large in countries like Italy, where the massive amount of "famous" artifacts tends to neglect other presences unless properly exposed, or when the remains are dramatically damaged leaving very few interpretation clues to the visitor. In such cases a virtual presentation of the Cultural Heritage site can be of great help, specially for explaining the evolution of its status, giving sometimes sense to few spare stones. The definition of these digital representations deal with two crucial aspects: on the one hand the possibility of 3D surveying the relics in order to have an accurate geometrical image of the current status of the artifact; on the other hand the presence of historical sources both in form of written text or images, that once properly matched with the current geometrical data, may help to recreate digitally a set of 3D models representing visually the various historical phases (diachronic model), up to the current one. The core of this article is the definition of an integrated methodology that starts from an high-resolution digital survey of the remains of an ancient building and develops a coherent virtual reconstruction from different historical sources, suggesting a scalable method suitable to be re-used for generating a 4D (geometry + time) model of the artifact. This approach has been experimented on the "Basilica di San Giovanni in Conca" in Milan, a very significant example for its complex historic evolution that combines evident historic values with an invisible presence inside the city.

  20. The Use of Neutron Technology in Archaeological and Cultural HeritageResearch

    Nations define themselves by their history and their customs. Their history is determined by both archaeological and archival evidence. The continuing development of a national culture is essential for the formation of a national identity. Both archaeological sites and cultural heritage artifacts are important to many nations because of income earned through tourism. This chapter discusses the use of neutron technology, one of a number of possible technologies, in the study of archaeological and cultural heritage artifacts. In particular descriptions of Neutron Activation Analysis, Neutron Diffraction, and Neutron Imaging Techniques will be given, and selected applications of these techniques to archaeology and cultural heritage artifacts will be given.

    Jerpasen, Gro B. Larsen, Kari C.

    2011-04-15

    This paper discusses different approaches of how visual impact on cultural heritage can be methodologically improved within Environmental Impact Assessment (EIA). During the recent decade, visual impact on cultural heritage and heritage sites has become a more frequent but contentious issue in public and academic discussions. Yet, within EIA issues relating to heritage sites and visual impact are rarely debated or critically reflected upon. Today most methods and theories on visual impact and cultural heritage within EIA are transferred from disciplines such as landscape architecture, architecture and geography. The article suggests how working with the concepts and definitions of site and setting can be a methodological tool for delimiting and clarifying visual impact on cultural heritage sites. The article also presents ways of how public participation can be a tool to start exploring the field of what the visual impact on cultural heritage implies and how it effects upon our understanding and appreciation of heritage sites. Examples from a Norwegian case are taken as illustrations to highlight these issues.

    In the field of cultural heritage, the main concern when a sample is analyzed is its safeguard, and this means that non-destructive techniques are required. In this work, we show how confocal Raman microscopy (CRM) may be successfully applied in the study of works of art as a valuable alternative to other well established techniques. CRM with a metallurgical objective was tested for the in depth study of thin samples that are of interest in the field of cultural heritage. The sensitivity of the instrumentation was first evaluated by analyzing single layers of pure polyethylene terephthalate (PET) films having a thickness of 12, 25, and 50 μm, respectively, and a multilayer sample of polypropylene (PP) and polyethylene (PE). Subsequently, the technique was applied to the analysis of historical dyed cotton yarns in order to check whether it was possible to achieve a better discrimination of the fibres' signals for an easier identification. A substantial improvement of the signal to noise ratio was found in the confocal arrangement with respect to the non-confocal one, suggesting the use of this technique for this kind of analysis in the field of cultural heritage. Furthermore, Raman spectroscopy in confocal configuration was exploited in the evaluation of cleaning performed on the mural painting specimens, treated with acrylic resin (Paraloid B72). Confocal Raman experiments were performed before and after laser cleaning (at different conditions) in order to monitor the presence and to approximate the polymer thickness: the method proved to be a valid comparative tool in assessment of cleaning efficiencies.

    Audiovisual creation is facing in Arab countries problems arising from the use of imported techniques in order to reconstitute or transform their own reality. Arab audiovisual producers see this technique as an easy and efficient way to reproduce reality or construct conventionally an artificial universe. Sometimes, audiovisuals have an absolute suggestion power; sometimes, these techniques are faced with total incredulity. From a diffusion point of view, audiovisuals in the Arab world have a very specific status. The effects of television, studied by western researchers in their cultural environment, are not reproduced in the same fashion in the Arab cultural world. In the Arab world, the word very often still competes successfully with the picture, even after the appearance and adoption of mass media. Finally, one must mention a very interesting situation resulting from a linguistic phenomenon which is specific to the Arab world: the existence of 2 communication languages, one noble but little used, the other dialectical but popular. In all Arab countries, the News, the most political program, is broadcasted in the classical language, despite the danger of meaning distortion in the least educated public. The reason is probably that the classical Arab language enjoys a sacred status. Arab audiovisuals are facing several obstacles to their total and autonomous realization. The contribution of the Arab audiovisual producers is relatively modest, compared to some other areas of cultural creation. Arab film-making is looking more and more for the cooperation of contemporary writers. Contemporary literature is a considerable source for the renewal of Arab audiovisual expression. A relationship between film and popular cultural heritage could be very usefully established in both directions. Audiovisuals should treat popular cultural manifestations as a global social fact on several significant levels. PMID:12261391

    Since 1989 the radiocarbon dating lab has their own graphitization system for 14C AMS dating but RICH (Royal Institute for Cultural Heritage) did not possess their own AMS and measurements were carried out in collaboration with other AMS facilities. In April 2013 the Micadas (Mini Carbon Dating System) AMS was installed at RICH in Brussels and after 1.5 year operation the high stability and performance of the Micadas can be demonstrated by repeated analyses of primary standard OXA II and secondary standards. Results of unknown samples measured on the RICH-Micadas and on other AMS systems are in good agreement.

    In the province of Chaco, Argentina, there is a very unique dispersion of metallic meteorites called ``Campo del Cielo''. One of the meteoric fragments of this dispersion, the meteorite called ``El Chaco'', consisting of 37 tons, is the second heaviest in the world. These meteorites are of great importance to the worldview of the Moqoit, aboriginal people that inhabit this region. For the local Creole population the meteorites are also relevant, that's why they have being cited in numerous documents and reports since the colonial period. During the first months of 2012, two Argentine artists and the Artistic Director of the German contemporary art exhibition called dOCUMENTA (13) tried to move ``El Chaco'' meteorite to Germany in order to exhibit it as an artistic object. Due to the fact that moving the meteorite could have a negative impact according to the Moqoit cosmology and that they were not able to participate in the decision they begun a manifestation against the movement of El Chaco. The opposition made by aboriginal communities and experts in cultural astronomy was able to stop the transfer. The whole process and its impact on the local community have promoted a deep discussion about art, science and cultural colonialism. In this paper we aim to address this debate and its consequences. This will allow us to think about contemporary forms of colonialism that are hidden in many scientific and artistic projects. Furthermore, we aim to debate about the most effective ways of protecting astronomical heritage in the Third World.

  6. Laser based diagnostics - from cultural heritage to human health

    2008-09-01

    An overview of applied laser-based diagnostics as pursued at the Division of Atomic Physics, Lund University, is given. The fields of application range from environmental monitoring including cultural heritage assessment, to biomedical applications. General aspects of laser-based methods are non-intrusiveness, high spectral- and spatial resolution, and data production in real-time. Different applications are frequently generically very similar irrespective of the particular context, which, however, decides the spatial and temporal scales as well as the size of the optics employed. Thus, volcanic plume mapping by lidar, and optical mammography are two manifestations of the same principle, as is fluorescence imaging of a human bronchus by an endoscope, and the scanning of a cathedral using a fluorescence lidar system. Recent applications include remote laser-induced break-down spectroscopy (LIBS) and gas monitoring in scattering media (GASMAS). In particular, a powerful method for diagnostics of human sinus cavities was developed, where free oxygen and water molecules are monitored simultaneously.

  7. Novel Neutron Imaging Techniques for Cultural Heritage Objects

    NASA Astrophysics Data System (ADS)

    Andreani, C.; Gorini, G.; Materna, T.

    The use of neutrons for cultural heritage (CH) research is illustrated with special reference to neutron tomography (NT) methods, providing three-dimensional (3D) images of neutron attenuation, and the analysis techniques known as prompt gamma-ray activation analysis (PGAA) and neutron resonance capture analysis (NRCA), providing the elemental composition of an object. PGAA and NRCA are well-established nondestructive methods for bulk analysis of CH objects, with sensitivities that can reach the parts-per-million range. By improving the spatial resolution of PGAA and NRCA it will be possible to measure the composition of small parts inside a large object or even to provide a full 3D map of the elemental composition of an artifact. The imaging techniques under development are called prompt gamma-ray activation imaging (PGAI), neutron resonance capture imaging (NRCI) and neutron resonance transmission (NRT) tomography. The NRCA experience at the GELINA neutron source is the starting point for the development of NRCI/NRT now taking place at the 100 times more powerful ISIS pulsed neutron source.

    When it comes to large scale mapping of limited areas especially for cultural heritage sites, things become critical. Optical and non-optical sensors are developed to such sizes and weights that can be lifted by such platforms, like e.g. LiDAR units. At the same time there is an increase in emphasis on solutions that enable users to get access to 3D information faster and cheaper. Considering the multitude of platforms, cameras and the advancement of algorithms in conjunction with the increase of available computing power this challenge should and indeed is further investigated. In this paper a short review of the UAS technologies today is attempted. A discussion follows as to their applicability and advantages, depending on their specifications, which vary immensely. The on-board cameras available are also compared and evaluated for large scale mapping. Furthermore a thorough analysis, review and experimentation with different software implementations of Structure from Motion and Multiple View Stereo algorithms, able to process such dense and mostly unordered sequence of digital images is also conducted and presented. As test data set, we use a rich optical and thermal data set from both fixed wing and multi-rotor platforms over an archaeological excavation with adverse height variations and using different cameras. Dense 3D point clouds, digital terrain models and orthophotos have been produced and evaluated for their radiometric as well as metric qualities.

    « Vulnerability of Cultural Heritage to Climate Change », European Master-Doctorate Course, Council of Europe, Strasbourg 7-11 September 2009 The character of Cultural Heritage is closely related to the climate, and the urban landscape and the built heritage have been designed with the local climate in mind. The stability of Cultural Heritage is, therefore, closely tied to its interactions with the ground and the atmosphere. Climate Change is thus expected to have either catastrophic or subtle effects on Cultural Heritage materials and Cultural Landscapes. The major aim of the 2009 Strasbourg Course is to ensure that young European students are informed on these important problems and will be able in the future to undertake rigorous ongoing scientific monitoring of changes in conditions of Cultural Heritage. The Programme of the Course will cover the following topics: • Heritage Climatology • Principles of Mitigation and Adaptation of Cultural Heritage to Climate Change • Impact of Climate Change on building structures • Dose-Response and Damage Functions for materials in a Changing Climate • Modelling sea salts transport and deposition • Modelling wetting and drying of historic buildings • Impact of Climate Change on building materials: stone, mortar, modern glass, stained glass windows • Impact of Climate Change on organic materials • Biological impact of Climate Change on Cultural Heritage • Sea level rise models and possible application to Cultural Heritage • Past, present and future for Venice • The policies and action plans of International Organisations (Council of Europe, UNESCO, ICCROM) The Course is addressed to young people with scientific background: physicists, chemists, geologists, biologists, engineers, because of the high scientific level of the background required to follow the lectures. Teaching will be delivered in English without any simultaneous translation. The teachers belong to European Universities, National

    Analytical applications of Laser Induced Breakdown Spectroscopy (LIBS), namely optical emission spectroscopy of laser-induced plasmas, have been constantly growing thanks to its intrinsic conceptual simplicity and versatility. Qualitative and quantitative analysis can be performed by LIBS both by drawing calibration lines and by using calibration-free methods and some of its features, so as fast multi-elemental response, micro-destructiveness, instrumentation portability, have rendered it particularly suitable for analytical applications in the field of environmental science, space exploration and cultural heritage. This review reports and discusses LIBS achievements in these areas and results obtained for soils and aqueous samples, meteorites and terrestrial samples simulating extraterrestrial planets, and cultural heritage samples, including buildings and objects of various kinds.

    Preventive conservation represents a working method and combination of techniques which helps in determining and controlling the deterioration process of cultural heritage in order to take the necessary actions before it occurs. It is acknowledged as important, both in terms of preserving and also reducing the cost of future conservation measures. Therefore, long-term monitoring of physical parameters influencing cultural heritage is necessary. In the context of Smart Cities, monitoring of cultural heritage is of interest in order to perform future comparative studies and load information into the cloud that will be useful for the conservation of other heritage sites. In this paper the development of an economical and appropriate acquisition data system combining wired and wireless communication, as well as third party hardware for increased versatility, is presented. The device allows monitoring a complex network of points with high sampling frequency, with wired sensors in a 1-wire bus and a wireless centralized system recording data for monitoring of physical parameters, as well as the future possibility of attaching an alarm system or sending data over the Internet. This has been possible with the development of three board's designs and more than 5000 algorithm lines. System tests have shown an adequate system operation. PMID:25815447

    Damage caused to objects of cultural heritage is one of the most serious detrimental effects of air pollutants. Within the 6th Framework Programme of the EU, the CULT-STRAT project is an inter-agency, multi-disciplinary project that has integrated research and monitoring information to provide answers to policy and management questions, which relate the effects of air pollutants on heritage and the management options available to mitigate them. The overall aim of the project has been to assess and predict the effects of different pollutants on materials and objects of cultural heritage in a multipollutant scenario and to identify indicators and thresholds levels of pollutants. These have been used for development of management strategies for sustainable maintenance and preventive conservation of European Cultural Heritage and air quality policy from continental to local scale. The present paper reports one of the studies carried out in the CULT-STRAT project at city level and focused on the town of Madrid (Spain). Different maps are shown for the present and possible future scenarios (2010 and 2020): inventory of stock of cultural heritage for each selected material, concentration of selected pollutants (SO 2, NO 2, O 3 and PM 10), corrosion (cast bronze) and recession (Portland limestone), exceedance of tolerable degradation thresholds for each material and corrosion-cultural heritage overlapped maps.

    Considerable damage has been done to the cultural heritage sites around the world ranging from natural erosion to artificial destruction. With the development of information sciences, frontier technologies are actively introduced to help protect cultural heritage sites. The new concept of a Digital Cultural Heritage has been presented for culture protection and is gradually becoming an efficient method to solve or to remit various difficult problems. This paper puts forward a digitalization method for cultural heritage sites which rationally integrates and utilizes multiform surveying measurements. These techniques have been successfully implemented into two projects, namely the Digital Mogao Grottos and the Chi Lin Nunnery reconstruction. Our results prove that the concept of and the techniques utilized in Digital Cultural Heritage can not only contribute to research, preservation, management, interpretation, and representation of cultural heritages but can also help resolve the conflicts between tourism and protection.

    Cultural Heritage means to inherent and cultivate the cultural disinclinations from one generation to next generation. It is possible by education as well as following the traditional livelihood of ours; it is conducted formal/consciously or informal/unconsciously. One of the traits of education is to hand on the cultural values and behaviour…

  19. Oblique Aerial Images and Their Use in Cultural Heritage Documentation

    NASA Astrophysics Data System (ADS)

    Höhle, J.

    2013-07-01

    Oblique images enable three-dimensional (3d) modelling of objects with vertical dimensions. Such imagery is nowadays systematically taken of cities and may easily become available. The documentation of cultural heritage can take advantage of these sources of information. Two new oblique camera systems are presented and characteristics of such images are summarized. A first example uses images of a new multi-camera system for the derivation of orthoimages, façade plots with photo texture, 3d scatter plots, and dynamic 3d models of a historic church. The applied methodology is based on automatically derived point clouds of high density. Each point will be supplemented with colour and other attributes. The problems experienced in these processes and the solutions to these problems are presented. The applied tools are a combination of professional tools, free software, and of own software developments. Special attention is given to the quality of input images. Investigations are carried out on edges in the images. The combination of oblique and nadir images enables new possibilities in the processing. The use of the near-infrared channel besides the red, green, and blue channel of the applied multispectral imagery is also of advantage. Vegetation close to the object of interest can easily be removed. A second example describes the modelling of a monument by means of a non-metric camera and a standard software package. The presented results regard achieved geometric accuracy and image quality. It is concluded that the use of oblique aerial images together with image-based processing methods yield new possibilities of economic and accurate documentation of tall monuments.

    Flood risk assessment in art cities poses many challenges for the presence of cultural heritage at risk, which is a damage category whose value is hardly monetizable. In fact, valuing cultural asset is a complex task, usually requiring more effort than a rough estimation of restoration costs. The lack of an adequate risk evaluation of the cultural asset may also lead to enormous difficulties and political problems for the accomplishment of the structural mitigation solutions. The aim of the work is to perform a first analysis of the risk to cultural heritage avoiding a full quantification of exposure. Here we present a case study of broad importance, which is the art city of Florence (Italy), affected by a devastating flood in 1966. In previous studies the estimated flood risk, neglecting damages to cultural heritage, was about 53 Mio€ /year. Nevertheless, Florence hosts 176 buildings officially classified as cultural heritage and thousands of paintings, sculptures and ancient books. Proceeding similarly to the commonly accepted flood risk assessment method, the annual expected loss in terms of cultural heritage/artworks is estimated.

    This paper documents the formulation of an international, interdisciplinary study, on a concerted European level, to prepare an innovative, reliable, independent and global knowledge base facilitating the use of today's and future optical measuring techniques for the documentation of cultural heritage. Cultural heritage professionals, color engineers and scientists share similar goals for the documentation, curation, long-term preservation and representation of cultural heritage artifacts. Their focus is on accuracy in the digital capture and remediation of artefacts through a range of temporal, spatial and technical constraints. A shared vocabulary to interrogate these shared concerns will transform mutual understanding and facilitate an agreed movement forward in cultural heritage documentation here proposed in the work of the COST Action Color and Space in Cultural Heritage (COSCH). The goal is a model that captures the shared concerns of professionals for a standards-based solution with an organic Linked Data model. The knowledge representation proposed here invokes a GUI interface for non-expert users of capture technologies, facilitates, and formulates their engagement with key questions for the field.

  3. ED-XRF analysis for Cultural Heritage: is quantitative evaluation always essential?

    2015-07-01

    Energy Dispersive X-Ray Fluorescence (ED-XRF) is a very suitable tool for examination of Cultural Heritage materials because of its simplicity, with no requirement for any sample preparation and the possibility of operating with portable instruments, and it can probably be considered the most useful non-destructive analytical technique for ancient valuable objects of archaeological, historical or artistic interest. As regards the possibility of getting quantitative analysis in archaeometric applications, the problems arising from the limited sensitivity in detecting low Z elements, the irregular shape or the non-homogeneous composition of the sample have generated a widespread opinion that only semi-quantitative analyses are possible in XRF applications to archaeometry. In fact, this is always true for non-homogeneous samples as, typically, painting layers. On the contrary, the problems deriving from limited sensitivity in detecting matrix light elements as well as from irregular surface under analysis can be solved in most cases. Notwithstanding, working on unique and not standardized objects requires to pay attention on details and to know how to choose correct parameters and calculation algorithms to obtain reliable results. Indeed opportunities to deal with these objects are very limited and results have implication in other fields, so that each information about materials and production technique is of great interest. Two typical materials of archaeological interest showing particular features are considered - namely high corroded metallic artefacts and ceramics - revealing that, even if in cultural heritage field detailed quantitative analysis is the goal, it is not always necessary as also qualitative information by XRF spectra increase the knowledge of artefact.

  4. Multispectral light metering system for cultural heritage diagnosis and conservation

    2013-05-01

    In the world of Cultural Heritage the first concern is all about Conservation of the works of art. A piece of art in bad shape is meant to deteriorate to an irreversible stage. To avoid this, quite often it's needed to go through one or more cycles of restoration to clean and consolidate the various elements of the piece. The very second concern, once the work of art is restored and in good and stable shape, is its fruition. At the end of the day why one should do all that restoration work if nobody then can access and view? Yet viewing and enjoying an artwork means that a visitor would be able to see it at its best, and this means, almost always, to have a good lighting system. Today, both restoration and fruition can greatly benefit of all the available technologies, and achieve very high level quality. The goal of this paper is the development of an exposimetric system suitable to be extremely useful as a tool for the the non invasive analysis, as well as for the lighting design and lighting systems monitoring. Many diagnosis techniques that are used before the restoration stage, require a suitable lighting system to allow to extract from the painting the maximum amount of information through the acquisition of images in the range of visible as well as UV and IR light. A standard exposimeter is for its own nature, sensitive only to the visible light, constrained by the standard photometric sensitivity curve V(lambda). A wide band exposimeter would be, on the other hand, an invaluable tool to get higher precision and to speed up multispectral wide band images acquisition, avoiding time wasting fail and try cycles to record the subject under wide spectrum conditions. The same equipment can be used to monitor the quality of the light in a expo lighting system at, for example, a museum or a gallery. The light hitting a piece of art has to allow the visitor to see and appreciate all the color shades, and to appreciate the contrast of dark and bright areas due only to

    2013-07-01

    The current research aims at showing as applications working on personal mobile communication terminals such as smartphones, can be useful for exploration of places and, at the same time, as tools able to develop interaction between cultural heritage and users. In this sense, the use of smartphone applications can be combined with GIS in order to make a platform of knowledge useful to support research studies in the field of cultural heritage, with specific reference to accessibility issues and to the combined use of integrated technologies like GPS, QR code and GIS, with the final aim to find an useful methodology for collecting data by visitors and visualizing them through mapping techniques. The research shows how the integration of different systems and technologies can be used as method for inquiring the interactions between users and cultural heritage in terms of accessibility to places. GPS devices can be used to record visitors movements (cultural routes) in terms of space and time; QR code can be used for users interaction with cultural heritage (tourists opinion, heritage ranking, facilities, accessibility); GIS software can be used for data management, analysis and mapping (tourist flows, more visited places). The focus of research is about a combination of information related to cultural routes with the information related to single cultural places. The focus of research is about a combination of information related to cultural routes with the information related to single cultural places. The current research shows the potential use of smartphone applications, as mobile device for collecting data, as means to record rides and more visited places by tourists. The research could be divided into three steps; the first one concerns with GPS that can be used to record routes; the second one deals with interaction between tourists and cultural heritage through a system based on QR code; the third one is about GIS, used as tool for management, analysis and

  11. A short pulse, free running, Nd : YAG laser for the cleaning of stone cultural heritage

    NASA Astrophysics Data System (ADS)

    Mazzinghi, Piero; Margheri, Fabrizio

    2003-09-01

    This paper presents a Nd : YAG laser operating in free running (FR) regime, with a pulse duration (20 μs) shorter than conventional systems (>200 μs), mainly developed for applications in laser cleaning of stones, especially for the restoration of cultural heritage. The system was also optimized to achieve high energy and low divergence, for easy coupling with optical fibers. The unusual pulse temporal regime induces a spiky behavior of the laser output which could also help in the application. Details on the technologies for the flashlamps power supplies, including the discharge circuits needed to achieve the short pulses, are given. Application trials on artworks and artificial samples are also discussed. Results show that the intermediate pulse duration avoids the mechanical damage induced by the photomechanical effect of Q-switch lasers and the thermal damage, as superficial melting, usually induced by long pulse FR lasers.

  12. μ-XRF analysis of glasses: a non-destructive utility for Cultural Heritage applications.

    2012-02-01

    This paper presents a μ-XRF analytical approach for a non-destructive study of Cultural Heritage glass finds. This technique can be used for quantitative analysis of small volumes of solid samples, with a sensitivity that is superior to the electron microprobe but inferior to an ICP-MS system. An experimental set-up with natural and synthetic glass standards is proposed here for the quantitative analyses of major and trace elements on glass objects which cannot be sampled such as small archaeological or historical artefacts from Cultural Heritage. The described method, performed by means of the commercial μ-XRF Eagle III-XPL, was applied to Islamic glass specimens of Sasanian production (III-VII century A.D.) previously analyzed by ICP-MS and SEM-EDS techniques (P. Mirti, M. Pace, M. Negro Ponzi and M. Aceto, Archaeometry, 2008, 50(3), 429-450; P. Mirti, M. Pace, M. Malandrino and M. Negro Ponzi, J. Archaeol. Sci., 36, 1061-1069; and M. Gulmini, M. Pace, G. Ivaldi, M. Negro Ponzi and P. Mirti, J. Non-Cryst. Solids, 2009, 355, 1613-1621) and coming from the archaeological site of Veh Ardasir in modern Iraq. Major elements (Na, Mg, Al, Si, K, Ca, Fe) of glass specimens show an accuracy better than 5%. Trace elements (Cr, Mn, Sr and Zr) display an accuracy better than 5% when the checked elements have a concentration >100 ppm by weight, whereas it is around 10% with a concentration <100 ppm by weight. μ-XRF is, therefore, a suitable elemental analysis technique for the non-destructive study of small glass finds due to its relatively good accuracy, reproducibility and low detection limits (∼tens ppm).

    Hyperspectral imaging was originally developed for remote sensing and astronomical applications, but adaptations of this technology have been of great benefit to the preservation of cultural heritage. Developments in noninvasive analytical techniques have advanced the preservation of cultural heritage materials by enabling the identification and analysis of a range of materials, utilizing their unique spectral response to nondestructively determine chemical composition, and determining states of deterioration and change due to environmental conditions. When used as a tool for noninvasive characterization of cultural heritage, these spectral imaging systems allow the collection of chemical identification information about materials without sampling, which is a critical factor for cultural heritage materials. The United States Library of Congress has been developing the application of hyperspectral imaging to the preservation and analysis of cultural heritage materials as a powerful noncontact technique. It allows noninvasive characterization of materials, by identifying and characterizing colorants, inks, and substrates with narrow-band illumination to protect the object while also monitoring deterioration or changes due to exhibit and other environmental conditions. Contiguous illumination from the ultraviolet, visible, and infrared spectral regions allows the capture of lost, obscured, and deteriorated information. The resulting image cube allows greater capabilities for mapping and coordinating a range of complementary chemical and spectral analyses. The capabilities of this technique are illustrated by a review of results from analysis of the Waldseemüller World Map, the L'Enfant plan for Washington, D.C., and the first draft of the U.S. Declaration of Independence.

    Social constructivism has been increasingly studied and implemented in science school education. Nevertheless, there is a lack of holistic studies on the implementation of social constructivist approach in primary science education in Confucian heritage culture. This study aims to determine to what extent a social constructivist approach is implemented in primary science education in Confucian heritage culture and to give explanations for the implementation from a cultural perspective. Findings reveal that in Confucian heritage culture a social constructivist approach has so far not implemented well in primary science education. The implementation has been considerably influenced by Confucian heritage culture, which has characteristics divergent from and aligning with those of social constructivism. This study indicates a need for design-based research on social constructivism-based science curriculum for Confucian heritage culture.

    Conceptualisations of attachment to one's nation of origin reflecting a symbolic caregiver can be found cross-culturally in literature, art, and language. Despite its prevalence, the relationship with one's nation has not been investigated empirically in terms of an attachment theory framework. Two studies employed an attachment theory approach to investigate the construct validity of symbolic attachment to one's nation of origin, and its association with acculturation (operationalized as heritage and mainstream culture identification). Results for Study 1 indicated a three-factor structure of nation attachment; the factors were labelled secure-preoccupied, fearful, and dismissive nation attachment. Hierarchical linear modelling was employed to control for differing cultures across participants. Secure-preoccupied nation attachment was a significant predictor of increased heritage culture identification for participants residing in their country of birth, whilst dismissive nation attachment was a significant predictor of decreased heritage culture identification for international migrants. Secure-preoccupied nation attachment was also associated with higher levels of subjective-wellbeing. Study 2 further confirmed the validity of the nation attachment construct through confirmatory factor analysis; the three-factor model adequately fit the data. Similar to the results of Study 1, secure-preoccupied nation attachment was associated with increased levels of heritage culture identification and psychological well-being. Implications of the tripartite model of nation attachment for identity and well-being will be discussed. PMID:23372673

    Cultural heritage represents a bridge between the contemporary society and the past populations, and a strong collaboration between archaeologists, art historians and analysts may lead to the decryption of the information hidden in an ancient object. Quantitative elemental compositional data play a key role in solving questions concerning dating, provenance, technology, use and the relationship of ancient cultures with the environment. Nevertheless, the scientific investigation of an artifact should be carried out complying with some important constraints: above all the analyses should be as little destructive as possible and performed directly on the object to preserve its integrity. Laser ablation sampling coupled to inductively coupled plasma-mass spectrometry (LA-ICP-MS) fulfils these requirements exhibiting comparably strong analytical performance in trace element determination. This review intends to show through the applications found in the literature how valuable is the contribution of LA-ICP-MS in the investigation of ancient materials such as obsidian, glass, pottery, human remains, written heritage, metal objects and miscellaneous stone materials. The main issues related to cultural heritage investigation are introduced, followed by a brief description of the features of this technique. An overview of the exploitation of LA-ICP-MS is then presented. Finally, advantages and drawbacks of this technique are critically discussed: the fit for purpose and prospects of the use of LA-ICP-MS are presented. PMID:19200475

    This paper presents a framework of introducing GIS technology to record and analyse cultural heritages in continuous spatial scales. The research team is developing a systematic approach to support heritage conservation research and practice on historical buildings, courtyards, historical towns, and archaeological sites ad landscapes. These studies are conducted not only from the property or site scales, but also investigated from their contexts in setting as well as regional scales. From these continues scales, authenticity and integrity of a heritage can be interpreted from a broader spatial and temporal context, in which GIS would contribute through database, spatial analysis, and visualization. The case study is the construction of a information indexing framework of Dagu Dock industrial heritage to integrate physical buildings, courtyards, natural settings as well as their intangible characteristics which are affiliated to the physical heritage properties and presented through historical, social and culture semantics. The paper illustrates methodology and content of recording physical and social/cultural semantics of culture heritages on different scales as well as connection between different levels of database.

    The cultural and artistic heritage has always been at the center of activities aimed at its preservation and enhancement. Italy is a country particularly rich in terms of heritage to be protected, where the high-risk due to natural hazard, as earthquakes, landslides and floods, which are adds to human activities, contribute to make the heritage more frail, land needs to be safeguarded and enhanced and new mass market technology can be considered as innovative tools for the documentation of cultural heritage. In order to increase our country on the artistic point of view, it must be known in an historical and cultural way. Moreover, it is important also to define the cultural heritage on metric terms, to be able to describe and represent it with the best approach, with the purpose to offer to the people who comes to visit our beautiful country, the reliable model of some important object, that is no longer in exposition. The possibility to use the mass-market devices can allow us to realize it, because they are available for the greater part of the visitors, in a photogrammetric way to reconstruct our models. In the last years, these devices have been very improved and the embedded sensors are becoming more and more efficient in terms of precision and reliability. Also several small video cameras are now used to document our travels and activities and to share them through Internet. In this scenario, the aim of this research is to study and validate the possibility to use mass-market technology for this purpose, testing four different devices (smartphones and video cameras) for the documentation of the cultural heritage.

    Tangible cultural heritage includes various categories of monuments and sites, from cultural landscapes and sacred sites to archaeological complexes, individual architectural or artistic monuments and historic urban centers. Such places are continuously impacted and weathered by several internal and external factors, both natural and human-induced, with rapid and/or slow onset, including natural hazards, such as earthquakes or extreme meteorological events, cumulative processes as well as the effects of humans, especially in conflict situations. A clear picture of endangered sites is not available. In particular, the list of List of World Heritage in danger mainly focuses on sites threaten by armed conflicts. New space technology based on radar interferometry (InSAR) is now capable to monitor, since 1992 and with mm precision, surface deformation for reflective targets named persistent scatterers, which consistently return stable signals to the radar satellites. Led by the Italian Institute for Environmental Protection and Research, and in collaboration with NERC British Geological Survey, Geological and Mining Institute of Spain, University of Milano-Bicocca and Cyprus University of Technology, the project PROTHEGO, co-funded in the framework of JPI on Cultural Heritage EU programme (2015-2018), will make an innovative contribution towards the analysis of geo-hazards in areas of cultural heritage in Europe. The project will apply novel InSAR techniques to monitor monuments and sites that are potentially unstable due to landslides, sinkholes, settlement, subsidence, active tectonics as well as structural deformation, all of which could be effected of climate change and human interaction. To magnify the impact of the project, the approach will be implemented in more than 400 sites on the UNESCO World Heritage List in geographical Europe. After the remote sensing investigation, detailed geological interpretation, hazard analysis, local-scale monitoring, advanced

    3D modeling of cultural heritage objects like artifacts, statues and buildings is nowadays an important tool for virtual museums, preservation and restoration. In this paper, we introduce a method to automatically design a minimal imaging network for the 3D modeling of cultural heritage objects. This becomes important for reducing the image capture time and processing when documenting large and complex sites. Moreover, such a minimal camera network design is desirable for imaging non-digitally documented artifacts in museums and other archeological sites to avoid disturbing the visitors for a long time and/or moving delicate precious objects to complete the documentation task. The developed method is tested on the Iraqi famous statue "Lamassu". Lamassu is a human-headed winged bull of over 4.25 m in height from the era of Ashurnasirpal II (883-859 BC). Close-range photogrammetry is used for the 3D modeling task where a dense ordered imaging network of 45 high resolution images were captured around Lamassu with an object sample distance of 1 mm. These images constitute a dense network and the aim of our study was to apply our method to reduce the number of images for the 3D modeling and at the same time preserve pre-defined point accuracy. Temporary control points were fixed evenly on the body of Lamassu and measured by using a total station for the external validation and scaling purpose. Two network filtering methods are implemented and three different software packages are used to investigate the efficiency of the image orientation and modeling of the statue in the filtered (reduced) image networks. Internal and external validation results prove that minimal image networks can provide highly accurate records and efficiency in terms of visualization, completeness, processing time (>60% reduction) and the final accuracy of 1 mm.

    The communication will present the today situation of astronomical and archaeo-astronomical heritage related to the World Heritage Convention along the past years till today. Some parallel events and works promoted strongly as the IAU - UNESCO initiative for the “year of astronomy” (2009). It was followed by a joint program by IAU and ICOMOS who is an official advisory body assessing the World Heritage Committee for the evaluation of nomination dossiers. Result of that works is an important publication by around 40 authors coming from 20 different countries all around the World: Heritage Sites of Astronomy and Archaeoastronomy in context of the UNESCO World Heritage Convention (2010-2011). A second volume is under preparation (2015). It was also accompanied by some initiatives like “Windows to the Universe” organisation and parallel constitution of local “Starlight Reserves”. Some regional meetings studying specific facets or regional heritage in the field giving significant knowledge progresses also accompanied global trend for astronomical heritage.WH assessment is defined by a relatively strict format and methodology. Key word is “demonstration of an Outstanding Universal Value” to justify the WH Listing by the Committee. Communication first examines requirements and evaluation practices about of the OUV demonstration for a given place in context of astronomical or archaeo-astronomical heritage. That means examination of the tangible attributes, inventory of the property in terms of unmoveable and moveable components and inventory of intangible issues related to the history (history of the place in context of the history of astronomy and cultural history). That is also related to apply to the site concept of integrity and authenticity level of the place and comparison with other similar places (WH site already listed, national WH Tentative List, other similar places in the region).Second issue of the communication is to give a glimpse on the

    Climate change is one of the main factors with a significant impact on changes of cultural heritage and landscapes. Exposed and buried archaeological remains are particularly endangered by effects of climate change processes hence it is of great importance to understand the type of risks and the degree of their impact on such assets. Some of the potential risks for cultural heritage and landscape include flooding, intense rainfall, increase in time of wetness, extreme events in temperature change, coastal flooding, drought, wind driven/transported agents (sand, rain or salt) and so forth. From the geo-science perspective, the topic of climate change and the risks it causes is of crucial importance for environmental monitoring in general and it is one of the main applications of the European program on Earth Observation Copernicus. The activities performed in CLIMA project - "Cultural Landscape risk Identification, Management and Assessment" have as one of the main tasks to combining the fields of remote sensing technologies, including the Sentinel data, and cultural heritage monitoring. Such interdisciplinary approach was undertaken in order to identify major climate change risks affecting archaeological heritage in rural areas in Cyprus and to identify the most suitable Earth Observation (EO) and ground-based methods that might be effective in the mapping, diagnostics and monitoring of such risks. This thorough analysis will support the overall design of the CLIMA platform based in EO data analysis, risk models and ground-based methods to provide integrated information for specialists in remote sensing but also to archeologists and policy makers engaged in heritage preservation and management. The case study selected for Cyprus is the awarded Nea Paphos archeological site and historical center of Paphos that is surrounding this UNSECO World Heritage site.

    The application of irradiation treatment for the protection of cultural heritage artefacts in Croatia was made possible by the development of radiation processing procedures at the Radiation Chemistry and Dosimetry Laboratory of the Ruđer Bo\\vsković Institute. After the upgrading of the 60Co gamma irradiation source in the panoramic irradiation facility in 1983 it became possible to perform both research and pilot plant-scale irradiations for sterilization, pasteurization and decontamination of various materials, including medical supplies, pharmaceuticals, cosmetics and foods, but also for disinfestation of cultural heritage artefects. The demand for irradiation treatment of cultural heritage objects has particularly increased as the increasing number of these objects, especially polychromic wooden sculptures, were requiring salvation, restauration and conservation as a consequence of direct and indirect damages inflicted to them during the war in Croatia, 1991-1995. The irradiation facility at the Ruđer Bo\\vsković Institute is briefly described and an account of its fifteen years' activities in the irradiation treatment of cultural heritage objects is given. Some case studies performed in cooperation with the Croatian Conservation Institute and other interested parties are presented, as well as some cases of protective and curative treatments for disinfestation and decontamination. International cooperations and activities are also mentioned.

    2015-08-01

    During the war in Bosnia and Herzegovina (1992-1995) cultural heritage was explicitly targeted and the state of destruction was extensive to both sacral and secular monuments. Two decades after the end of hostilities the perception of the historic environment is still defined from the angles of national, religious or ethnic belonging. Enabling recognition, reconciliation, tolerance and respect within the community of Stolac, Bosnia & Herzegovina through a better understanding and sharing of cultural heritage was the focus of this project. Stolac is representative of the problems in the region and stands out for its particularly sharp divisions. Until recently there was segregation with local schools and their curriculum was divided with cultural heritage generally not addressed. How can this small community engage with heritage and develop a dialogue that encourages tolerance, respect and as a base for development? How does one understand, then document areas significance to the community? Finally, how can technology assist? The focus of this paper is to relate the experiences and findings of a project that incorporated participatory imaging mapping and the use of technology to bridge between the internal borders of this small community. It will outline a methodology, experiences of the participants and results from their exercises in order to assist other communities facing similar issues.

    Terahertz pulse imaging (TPI) is a novel noncontact, nondestructive technique for the examination of cultural heritage artifacts. It has the advantage of broadband spectral range, time-of-flight depth resolution, and penetration through optically opaque materials. Fiber-coupled, portable, time-domain terahertz systems have enabled this technique to move out of the laboratory and into the field. Much like the rings of a tree, stratified architectural materials give the chronology of their environmental and aesthetic history. This work concentrates on laboratory models of stratified mosaics and fresco paintings, specimens extracted from a neolithic excavation site in Catalhoyuk, Turkey, and specimens measured at the medieval Eglise de Saint Jean-Baptiste in Vif, France. Preparatory spectroscopic studies of various composite materials, including lime, gypsum and clay plasters are presented to enhance the interpretation of results and with the intent to aid future computer simulations of the TPI of stratified architectural material. The breadth of the sample range is a demonstration of the cultural demand and public interest in the life history of buildings. The results are an illustration of the potential role of TPI in providing both a chronological history of buildings and in the visualization of obscured wall paintings and mosaics.

  16. X-ray fluorescence imaging system for fast mapping of pigment distributions in cultural heritage paintings

    Conventional X-ray fluorescence imaging technique uses a focused X-ray beam to scan through the sample and an X-ray detector with high energy resolution but no spatial resolution. The spatial resolution of the image is then determined by the size of the exciting beam, which can be obtained either from a synchrotron source or from an X-ray tube with a micro-capillary lens. Such a technique based on a pixel-by-pixel measurement is very slow and not suitable for imaging large area samples. The goal of this work is to develop a system capable of simultaneous imaging of large area samples by using a wide field uniform excitation X-ray beam and a position sensitive and energy dispersive detector. The development is driven by possible application of such a system to imaging of distributions of hidden pigments containing specific elements in cultural heritage paintings, which is of great interest for the cultural heritage research. The fluorescence radiation from the area of 10 × 10 cm2 is projected through a pinhole camera on the Gas Electron Multiplier detector of the same area. The detector is equipped with two sets of orthogonal readout strips. The strips are read out by the GEMROC Application Specific Integrated Circuits (ASIC)s, which deliver time and amplitude information for each hit. This ASIC architecture combined with a Field Programmable Gate Array (FPGA) based readout system allows us to reconstruct the position and the total energy of each detected photon for high count rates up to 5 × 106 cps. Energy resolution better than 20% FWHM for the 5.9 keV line and spatial resolution of 1 mm FWHM have been achieved for the prototype system. Although the energy resolution of the Gas Electron Multiplier (GEM) detector is, by principle, not competitive with that of specialised high energy resolution semiconductor detectors, it is sufficient for a number of applications. Compared to conventional micro-XRF techniques the developed system allows shortening of the

    2015-01-01

    Many repatriates find it challenging to readjust to their heritage culture after spending a significant period of time abroad. Research on predictors of readjustment, however, remains limited. The present study in particular investigated the identification of third culture individuals (TCIs) – that is, individuals who spent their formative years outside of their heritage culture - with an abstract, third culture. Our findings demonstrated that TCIs’ identification with the third culture was empirically distinct from that of the heritage and host cultures. The present study further examined whether several variables – sojourner type (TCI vs. non-TCI), perceived conflict between heritage and host culture, perceived cultural distance, and cultural identification with heritage and other cultures – predicted psychological readjustment (stress, anxiety, depression and overall psychological readjustment). The results showed that strong heritage culture identification was associated with better psychological readjustment, whereas cultural conflict was generally associated with poorer readjustment. Furthermore, sojourner type significantly moderated the latter association, such that cultural conflict predicted the stress aspect of psychological readjustment for non-TCIs, but not for TCIs. As the present investigation is the first study to empirically establish identification with a ‘third culture’ we discuss implications for the literature on third culture individuals and psychological adjustment upon re-entry.

    In the recent years, the concepts of seismic risk vulnerability and structural health monitoring have become very important topics in the field of both structural and civil engineering for the identification of appropriate risk indicators and risk assessment methodologies in Cultural Heritages monitoring. The latter, which includes objects, building and sites with historical, architectural and/or engineering relevance, concerns the management, the preservation and the maintenance of the heritages within their surrounding environmental context, in response to climate changes and natural hazards (e.g. seismic, volcanic, landslides and flooding hazards). Within such a framework, the complexity and the great number of variables to be considered require a multi-disciplinary approach including strategies, methodologies and tools able to provide an effective monitoring of Cultural Heritages form both scientific and operational viewpoints. Based on this rationale, in this study, an advanced, technological and operationally-oriented approach is presented and tested, which enables measuring and monitoring Cultural Heritage conservation state and geophysical/geological setting of the area, in order to mitigate the seismic risk of the historical public goods at different spatial scales*. The integration between classical geophysical methods with new emerging sensing techniques enables a multi-depth, multi-resolution, and multi-scale monitoring in both space and time. An integrated system of methodologies, instrumentation and data-processing approaches for non-destructive Cultural Heritage investigations is proposed, which concerns, in detail, the analysis of seismogenetic sources, the geological-geotechnical setting of the area and site seismic effects evaluation, proximal remote sensing techniques (e.g. terrestrial laser scanner, ground-based radar systems, thermal cameras), high-resolution aerial and satellite-based remote sensing methodologies (e.g. aeromagnetic surveys

    2015-01-01

    For millennia, peoples around the world have tattooed human skin to communicate various ontological, psychosocial, and sociocultural concepts encompassing beauty, cultural identity, status and position, medicine, and supernatural protection. As a system of knowledge transmission, tattooing has been and continues to be a visual language of the skin whereby culture is inscribed, experienced, and preserved in a myriad of specific ways. If we are to fully comprehend the meanings that tattoos have carried across human history and into the present, then it would be useful to explore some of the ways tattoos, as instruments that transmit culture, have been deployed cross-culturally through time.

    Cultural heritage plays a key role for communities in terms of both identity and economic value. It is often under serious threat by natural hazards, nevertheless, quantitative assessments of risk are quite uncommon. This work addresses the flood risk assessment to cultural heritage in an exemplary art city, which is Florence, Italy. The risk assessment method here adopted borrows the most common definition of flood risk as the product of hazard, vulnerability and exposure, with some necessary adjustments. The risk estimation is carried out at the building scale for the whole UNESCO site, which coincides with the historical centre of the city. A distinction in macro- and micro-damage categories has been made according to the vulnerability of the objects at risk. Two damage macro-categories are selected namely cultural buildings and contents. Cultural buildings are classified in damage micro-categories as churches/religious complexes, libraries/archives and museums. The damages to the contents are estimated for four micro-categories: paintings, sculptures, books/prints and goldsmith's art. Data from hydraulic simulations for different recurrence scenarios, historical reports of the devastating 1966 flood and the cultural heritage recognition sheets allow estimating and mapping the annual expected number of works of art lost in absence of risk mitigation strategies.

    2009-01-29

    The analysis of cultural Heritage objects is often technically challenging. When analyzing micro-fragments, the amount of matter is usually very tiny, hence requiring sensitive techniques. These samples, in particular painting fragments, may present multi-layered structures, with layer thickness of {approx}10 {mu}m. It leads to favor micro-imaging techniques, with a good lateral resolution (about one micrometer), that manage the discriminative study of each layer. Besides, samples are usually very complex in term of chemistry, as they are made of mineral and organic matters, amorphous and crystallized phases, major and minor elements. Accordingly, a multi-modal approach is generally essential to solve the chemical complexity of such hybrid materials. Different examples will be given, to illustrate the various possibilities of synchrotron-based micro-imaging techniques, such as micro X-ray diffraction, micro X-ray fluorescence, micro X-ray absorption spectroscopy and micro FTIR spectroscopy. Focus will be made on paintings, but the whole range of museum objects (going from soft matter like paper or wood to hard matter like metal and glass) will be also considered.

    The preliminary phase in any architectural heritage project is to obtain metric measurements and documentation of the building and its individual elements. On the other hand, conventional measurement techniques require tremendous resources and lengthy project completion times for architectural surveys and 3D model production. Over the past two decades, the widespread use of laser scanning and digital photogrammetry have significantly altered the heritage documentation process. Furthermore, advances in these technologies have enabled robust data collection and reduced user workload for generating various levels of products, from single buildings to expansive cityscapes. More recently, the use of procedural modelling methods and BIM relevant applications for historic building documentation purposes has become an active area of research, however fully automated systems in cultural heritage documentation still remains open. In this paper, we present a semi-automated methodology, for 3D façade modelling of cultural heritage assets based on parametric and procedural modelling techniques and using airborne and terrestrial laser scanning data. We present the contribution of our methodology, which we implemented in an open source software environment using the example project of a 16th century early classical era Ottoman structure, Sinan the Architect's Şehzade Mosque in Istanbul, Turkey.

    The aim of this paper is to clarify and discuss how quality, relevance, attitudes, beliefs and transfer value act as underlying driving forces in the development of the Cultural Heritage theme in EIAs. One purpose is to identify and discuss some conditions that can better environmental assessment in order to increase the significance of EIA in decision-making with regard to Cultural Heritage. The main tools used are different research methods designed for analyses of quality and quality changes, primarily based on the relevant opinions of 160 people occupied with Cultural Heritage in EIA in Norway. The study is based on a review of 40 types of EIAs from 1991 to 2000, an online questionnaire to 319 (160 responded) individuals from 14 different backgrounds, and interviews with three institutions in Sweden and Denmark. The study confirms a steadily increasing quality on EIRs over time, parallel with an improvement of the way in which Cultural Heritage is treated in EIA. This is supported by both the interviews and the qualitative comments regarding the survey. Potential for improvements is shown to be a need for more detailed background material as well as more use of adequate methods. The survey shows the existence of a wide variety of negative views, attitudes and beliefs, but the consequences of this are difficult to evaluate. However, most certainly, negative attitudes and beliefs have not been powerful enough to be detrimental to the quality of Cultural Heritage component, as nothing in the study indicates that negative attitudes and myths are undermining the system of EIA. The study shows the importance of having on-going discussions on quality and quality change over time by people involved in EIA, and how this is a necessary condition for successful implementation and acceptance. Beliefs and negative attitudes can also be a catalyst for developing better practice and advancing new methodology. In addition, new EIA countries must be prepared for several years

    In recent years, some workshops and research cases have arisen in China to seek for suitable ways for heritage conservation and development of historic villages. However, the issue of multi-cooperation has not been much mentioned in research works. The case of Cangdong Project in Guangdong Province is a social enterprise. It is a center focusing on heritage education. It organizes tailor-made workshops for interested people from all over China and Hong Kong, Macao and overseas, including university courses for credits, summer/winter camps for primary and middle school students, as well as common people who are interested in heritage conservation. The purpose of the education center is to enhance heritage/cultural interest of the younger generations and common people, and try to work with local villagers to build a wealthy community. Nowadays, more and more villagers moved out for work and the countryside population in China is decreasing, this project also aims to create work opportunities for villagers through heritage conservation projects, so that the villagers can be willing to stay. The project focuses more in a sustainable way for community development. It has been five years since the project was set up in Cangdong Village. The project team worked with villagers, city people, students, scholars, different levels of local governments, investors, Medias, charitable organizations, as well as the market of tourism. As such, a platform of multi-cooperation for the above parties has formed during the past five years. This paper takes the Project experience from 2010-2015 as the case to study multi-cooperation in the field of heritage conservation in China, as well as to discuss how to co-operate the subjective initiatives of different stokeholds.

    2014-01-01

    Actinobacteria, cyanobacteria, algae, and fungi form subaerial biofilm (SAB) that can lead to material deterioration on artistic stone and frescoes. In studying SAB on cultural heritage surfaces, a general approach is to combine microscopy observations and molecular analyses. Sampling of biofilm is performed using specific adhesive tape and sampling of SAB and the substrate with sterile scalpels and chisels. Biofilm observations are carried out using optical and scanning electron microscopy. Specific taxa and EPS in biofilm can be readily visualized by fluorochrome staining and subsequent observation using fluorescence or confocal laser scanning microscopy. The observation of cross sections containing both SAB and the substrate shows if biofilm has developed not only on the surface but also underneath. Following nucleic acid extraction, 16S rRNA gene sequencing is used to identify bacterial taxa, while 18S rRNA gene and internal transcribed spacer (ITS) sequence analysis is used to study eukaryotic groups. In this chapter, we illustrate the protocols related to fluorescence in situ hybridization (FISH), scanning electron microscopy (SEM), and denaturing gradient gel electrophoresis (DGGE).

    The five Arab Gulf countries of Kuwait, Bahrain, Qatar, the United Arab Emirates and Oman possess many shared characteristics and historical ties across their common peninsula. The prime factor uniting them is the historical nature of their entwined involvement with peoples and nations beyond the region. That the Gulf has been an important water passageway since ancient times suggests that the inhabitants of its shores met early on with other civilizations. The knowledge of one's roots, history, and traditional arts supports awareness of inherited culture and can help contextualize and illuminate community reflection and identification. The intricacy of the recording and understanding processes of documentation requires skilled professionals, with knowledge and awareness for the associated tasks. Responsible of cultural heritage should provide the adequate documentations, recording and updating of the records. Collaboration of different individuals such as specialist heritage, archaeologists, surveyors, conservators, researchers, architectural historians, and many other expert personnel is the golden key of successful documentation. The purpose of this document is to show the authorities of Gulf Arab countries and their planning measures, management and sharing effect of recording the cultural heritage. This essay identifies key points in the approach to contextualizing and developing cultural identity in a way that respects organic qualities. Through highlighting a number of archeological ruins and outlining management plans, the essay explores frameworks that can be applied to promote and preserve integral identity of important sites and their greater surrounding communities.

    With the development of computer technology and practical verification, digital virtual technology has matured and is increasingly being widely applied to cultural heritage protection and research. With this advancement in technology, there is pressing need to simplify heritage-related puzzles. Thus the main question that has increasingly become the most central and fundamental problem in heritage digitalization work is how to choose the "proper technology" that provides support directly, accurately and rapidly for the research, protection and exchange of cultural heritage. Based on the principles of "authenticity" and "completeness" found in the Venice Charter in regards to dealing with cultural heritage; this paper proposes the concept of the component library which facilitates the improvement and efficiency of virtual reconstruction, provides a visual discussion platform for cultural heritage protection, virtual scene construction, accuracy assessment, and multi-space-time exhibition; thereby implementing the spirit of tolerance and respect found in the Nara Document on Authenticity. The paper further aims to illustrate the significance of the Qing dynasty imperial garden architectural component library for cultural heritage study and protection, the principles for virtual library construction, use and maintenance of the library, and classification approaches, and also provide some suggestions about making high quality 3D models and effective means for database integration.

    Here, we explore new, more accessible ways of modeling 3D data sets that both professionals and amateurs can employ in areas such as architecture, forensics, geotechnics, cultural heritage, and even hobbyist modeling. To support our arguments, we present images from a recent case study in digital preservation of cultural heritage using a mid-range laser scanner. Our appreciation of the increasing variety of methods for capturing 3D spatial data inspired our research. Available methods include photogrammetry, airborne lidar, sonar, total stations (a combined electronic and optical survey instrument), and midand close-range scanning.1 They all can produce point clouds of varying density. In our case study, the point cloud produced by a mid-range scanner demonstrates how open source software can make modeling and disseminating data easier. Normally, researchers would model this data using expensive specialized software, and the data wouldn't extend beyond the laser-scanning community. PMID:20650714

    Turkey is one of the most seismically active regions in the world. Major earthquakes with the potential of threatening life and property occur frequently here. In the last decade, over 50,000 residents lost their lives, commonly as a result of building failures in seismic events. The Cappadocia region is one of the most important touristic sites in Turkey. At the same time, the region has been included to the Word Heritage List by UNESCO at 1985 due to its natural, historical and cultural values. The region is undesirably affected by several environmental conditions, which are subjected in many previous studies. But, there are limited studies about the seismic evaluation of the region. Some of the important historical and cultural heritage sites are: Goreme Open Air Museum, Uchisar Castle, Ortahisar Castle, Derinkuyu Underground City and Ihlara Valley. According to seismic hazard zonation map published by the Ministry of Reconstruction and Settlement these heritage sites fall in Zone III, Zone IV and Zone V. This map show peak ground acceleration or 10 percent probability of exceedance in 50 years for bedrock. In this connection, seismic hazard assessment of these heritage sites has to be evaluated. In this study, seismic hazard calculations are performed both deterministic and probabilistic approaches with local site conditions. A catalog of historical and instrumental earthquakes is prepared and used in this study. The seismic sources have been identified for seismic hazard assessment based on geological, seismological and geophysical information. Peak Ground Acceleration (PGA) at bed rock level is calculated for different seismic sources using available attenuation relationship formula applicable to Turkey. The result of the present study reveals that the seismic hazard at these sites is closely matching with the Seismic Zonation map published by the Ministry of Reconstruction and Settlement.

    Portugal has established itself as an independent state on October, 5th 1143 being confined to the south-eastern tip of Europe, with sealed land access to the rest of the continent by the others Iberian Peninsula kingdoms, enemies at the time who did not accept Portuguese autonomy. From the fourteenth century, the history of Portugal reports a period of epic discoveries. New commercial maritime routes have been established. Those routes sailing around Africa, passing through India, drove Portuguese people to Macao and Timor. To the East other routes reach the South American continent. Besides commercial interest, and because the church also financed these trips, they had the mission to evangelize the native peoples that were found. In every formed captaincies, over 29 actual countries, numerous churches, hospitals and fortifications were built. Combining a long tradition and mastery of monumental stone building and stonemasonry, which dates back to the Roman Period, Portuguese were able to combine the need to provide ships stability, using already worked stone as ballast. When arrived to these remote locations, quickly and with few local resources, could erect towering and admirable structures that still prevail today. Most of these regions were colonized and gave rise to independent countries in the 70's of the 20th Century, in some of them Portuguese is the official language and these constitutes the Community of Portuguese Language Countries (CPLP). This work shows that in addition to the language, traditions, customs, and architecture, there's also a very rich Portuguese Natural Stones monumental heritage building record, which constitutes a very strong link that binds this so special community.

    Both assessment and mitigation of seismic vulnerability connected to cultural heritages monitoring are non-trivial issues, based on the knowledge of structural and environmental factors potential impacting the cultural heritage. A holistic approach could be suitable to provide an effective monitoring of cultural heritages within their surroundings at different spatial and temporal scales. On the one hand, the analysis about geometrical and structural properties of monuments is important to assess their state of conservation, their response to external stresses as well as anomalies related to natural and/or anthropogenic phenomena (e.g. the aging of materials, seismic stresses, vibrational modes). On the other hand, the investigation of the surrounding area is relevant to assess environmental properties and natural phenomena (e.g. landslides, earthquakes, subsidence, seismic response) as well as their related impacts on the monuments. Within such a framework, a multi-disciplinary system has been developed and here presented for the monitoring of cultural heritages for seismic vulnerability assessment and mitigation purposes*. It merges geophysical investigations and modeling, in situ measurements and multi-platforms remote sensing sensors for the non-destructive and non-invasive multi-scales monitoring of historic buildings in a seismic-prone area. In detail, the system provides: a) the long-term and the regional-scale analysis of buildings' environment through the integration of seismogenic analysis, airborne magnetic surveys, space-borne Synthetic Aperture Radar (SAR) and multi-spectral sensors. They allow describing the sub-surface fault systems, the surface deformation processes and the land use mapping of the regional-scale area on an annual temporal span; b) the short-term and the basin-scale analysis of building's neighborhood through geological setting and geotechnical surveys, airborne Light Detection And Radar (LiDAR) and ground-based SAR sensors.

    Analysis by laser-induced breakdown spectroscopy (LIBS) is compared, on the basis of a hybrid experimental set-up, with laser ablation time-of-flight mass spectrometry (LA-TOF-MS) for the characterization of materials relevant to cultural heritage. The present study focuses on the analysis of selected paint materials such as lithopone, a white inorganic pigment, and two synthetic organic paint formulations, lemon yellow and phthalocyanine blue. Optical emission spectra, obtained by LIBS, lead to rapid, straightforward identification of the elemental content of the paint samples while mass spectra yield, additionally to elemental analysis, complementary isotopic analysis and, more importantly, enable detection of molecules and molecular fragments, permitting a more complete structural and compositional characterization of composite materials. Mass spectra were recorded either simultaneously with the optical emission ones, or sequentially. The latter was preferred for materials having significantly lower fluence threshold for desorption/ionization relative to plasma formation resulting to optimum mass resolution and minimal surface damage. In all, the results of this study demonstrate the advantages of instrumentally complementing LIBS with TOF-MS in relation to applications in cultural heritage materials analysis, with exciting prospects when laser ablation sampling can be carried out under ambient atmosphere.

  19. Documentation and Cultural Heritage Inventories - Case of the Historic City of Ahmadabad

    NASA Astrophysics Data System (ADS)

    Shah, K.

    2015-08-01

    Located in the western Indian state of Gujarat, the historic city of Ahmadabad is renowned for the unparalleled richness of its monumental architecture, traditional house form, community based settlement patterns, city structure, crafts and mercantile culture. This paper describes the process followed for documentation and development of comprehensive Heritage Inventories for the historic city with an aim of illustrating the Outstanding Universal Values of its Architectural and Urban Heritage. The exercise undertaken between 2011 & 2014 as part of the preparation of world heritage nomination dossier included thorough archival research, field surveys, mapping and preparation of inventories using a combination of traditional data procurement and presentation tools as well as creation of advanced digital database using GIS. The major challenges encountered were: need to adapt documentation methodology and survey formats to field conditions, changing and ever widening scope of work, corresponding changes in time frame, management of large quantities of data generated during the process along with difficulties in correlating existing databases procured from the local authority in varying formats. While the end result satisfied the primary aim, the full potential of Heritage Inventory as a protection and management tool will only be realised after its acceptance as the statutory list and its integration within the larger urban development plan to guide conservation, development and management strategy for the city. The rather detailed description of evolution of documentation process and the complexities involved is presented to understand the relevance of methods used in Ahmadabad and guide similar future efforts in the field.

    Air pollutants, together with climatic parameters, are of major importance for the deterioration of cultural heritage monuments. Atmospheric pollution is widely recognized as one of the major anthropogenic threats to architectural cultural heritage, in particular when associated with water absorption phenomena. Atmospheric particle deposition on surfaces of Monuments (of cultural heritage interest) may cause an aesthetic impact induced by a series of chemical reactions. Therefore there is a need for systematic monitoring and mapping of air pollution for areas where important archaeological sites and monuments are found. observation techniques, such as the use of satellite image for the retrieval of Aerosol Optical Thickness (AOT), are ideal for this purpose. In this paper, all important monuments of the Paphos District, listed by the Department of Antiquities of Cyprus, have been mapped using Geographical Information Systems. Several recent (2012) MODIS satellite images (both Aqua and Terra) have been used to extract the AOT values in this area. Multi-temporal analysis was performed to identify areas of high risk where AOT values are considered to be high. In situ observations have been also carried out to verify the results.

    Microorganisms (bacteria, archaea and fungi), in addition to lichens and insect pests, cause problems in the conservation of cultural heritage because of their biodeteriorative potential. This holds true for all types of historic artefacts, and even for art made of modern materials, in public buildings, museums and private art collections. The variety of biodeterioration phenomena observed on materials of cultural heritage is determined by several factors, such as the chemical composition and nature of the material itself, the climate and exposure of the object, in addition to the manner and frequency of surface cleaning and housekeeping in museums. This study offers a review of a variety of well-known biodeterioration phenomena observed on different materials, such as stone and building materials, objects exhibited in museums and libraries, as well as human remains and burial-related materials. The decontamination of infected artefacts, exhibition rooms and depots incurs high expenditure for museums. Nevertheless, the question has to be raised: whether the process of biodeterioration of cultural heritage can or should be stopped under all circumstances, or whether we have to accept it as a natural and an implicit consecution of its creation. This study also highlights critically the pros and cons of biocide treatments and gives some prominent examples of successful and unsuccessful conservation treatments. Furthermore, an outlook on the future research needs and developments in this highly interesting field is given. PMID:24100684

    3D detailed models derived from digital survey techniques have increasingly developed and focused in many field of application. The high detailed content and accuracy of such models make them so attractive and usable for large sets of purposes in Cultural Heritage. The present paper focuses on one of the main techniques used nowadays for Cultural Heritage survey and documentation: the image matching approach or Structure from Motion (SfM) technique. According to the low cost nature and the rich content of derivable information, these techniques are extremely strategic in poor available resources sectors such as Cultural Heritage documentation. After an overview of the employed algorithms and used approaches of SfM computer vision based techniques, the paper is focused in a critical analysis of the strategy used by two common employed software: the commercial suite Agisoft Photoscan and the open source tool MicMac realized by IGN France. The experimental section is focused on the description of applied tests (from RPAS data to terrestrial acquisitions), purposed to compare different solutions in various featured study cases. Finally, the accuracy assessment of the achieved products is compared and analyzed according to the strategy employed by the studied software.

  3. a New Tool for Facilitating the Retrieval and Recording of the Place Name Cultural Heritage

    NASA Astrophysics Data System (ADS)

    Bozzini, C.; Conedera, M.; Krebs, P.

    2013-07-01

    Traditional place names (toponyms) represent the immaterial cultural heritage of past land uses, particular characteristics of the territory, landscape related events or inhabitants, as well as related cultural and religious background. In Euopean countries where the cultural landscape has a very long history, this heritage is particularly considerable. Often most of the detailed knowledge about traditional place names and their precise localization is non-written and familiar only to old local native persons who experienced the former rural civilization. In the next future this important heritage will be seriously threatened because of the physical disappearance of its living custodians. One of the major problems that one has to face, when trying to trace and document the knowledge related to place names and their localization, is to translate the memory and the former landscape experiences of the respondents into maps and structured records. In this contribution we present a new tool based on the monoplotting principle and ad hoc developed to enable the synchronization of terrestrial oblique landscape pictures with the represented digital elevation model. The local respondents are then just asked to show the place name localization on historical landscape pictures they are familiar with. The tool automatically gives back the corresponding world coordinates, what makes the interviewing process more rapid and smooth as well as motivating and less stress-inducing for the informants.

    This contribution focuses on spectrometric analyses carried out on crust samples covering the stone surface of the boundary walls of the Tower of London. The main goal of this research is to investigate the degradation processes related to the environmental impact on cultural heritage. Specifically, the chemical contamination of stone substrate in the Tower of London due to the crust formation was examined through laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). This technique allowed us to achieve a complete characterization of the damage layers in terms of trace elements. In addition, optical microscopy (OM), scanning electron microscopy coupled with energy-dispersive X-ray spectrometry (SEM-EDS) and infrared spectroscopic techniques (FT-IR) were also used for an exhaustive characterization of the examined samples. Results obtained demonstrated that such a geochemical approach represents a powerful diagnostic tool in the study of black crusts, since it represents a reliable indicator of the environmental pollution. The higher concentrations of most heavy metals in black crusts with respect to the underlying stone suggest that crusts were greatly influenced by atmospheric inputs in their formation, mainly represented by mobile combustion sources. In addition, the possibility of analyzing in some samples the portion of altered substrate allowed us to hypothesize that some specific heavy metals tend to migrate from the crust to the unaltered substrate over time, becoming catalysts for the formation of new crust. Therefore, this research focuses on the role of diagnostics in order to plan suitable cleaning and consolidation intervention aimed at a better protection of the monument.

    The documentation of Cultural Heritage asset is the basis for all the interventions and policies on Cultural heritage conservation and management. The documentation is mainly based on historic knowledge and metric survey. As far as historic knowledge is concerned many information are still recorded and preserved inside written documents that are usually not easy to reach and correctly understandable by all the experts that have specific responsibilities on Cultural Heritage. The digitalization of documents (hardly faced in the last years) is not sufficient to guarantee the effective access to the historical information useful inside a documentation process. The documentation always needs an historical interpretation based on a critical reading produced by linking heterogeneous materials. Iconography also is an important source when it is correctly interpreted and linked to other sources. IT development and digital technology diffusion allowed offering new way to record, organize and share historical information: GIS and 3D modeling can be used as standard approaches to transfer the historical knowledge in a proper way to specialists involved in Cultural Heritage conservation and management. They have been generally used as tool to represent information for different targets, the ones mostly for specialized users, the others for edutainment. GIS are largely diffused yet in the Cultural Heritage management, and 3D modeling is wide spread used in museums communication. Nevertheless, both of them have more potential. They could be integrated in order to manage different data set related with the same matter. They could be used to make new research by surveying and improving interpretation in a way ready to transmit the outcomes. To produce a new generation of affordable digital historical products is necessary that the GIS and 3D modeling design and realization would be developed in a multidisciplinary approach that must be explained and demonstrated to the people that

  7. Legal and Ethical Issues Related to the Management of Cultural Heritage in Space

    NASA Astrophysics Data System (ADS)

    Walsh, Justin

    The recent discovery of water in darkened craters of the Moon's south pole is only the latest development drawing public and corporate interest to the possibilities of research and travel in outer space. Scientists pursuing fusion-generated power as a solution to global energy needs have also noted the relative abundance of Helium-3, an efficient fuel, on the Moon's surface, and there is the promise of other precious resources there as well. The implantation of colonies on the Moon or Mars, discussed for many decades as science fiction, therefore seems increasingly likely to happen. Some private companies and members of the public are even looking forward to the days when tourists will be able to travel for leisure beyond the earth's atmosphere. Most notably, the X Prize Foundation and Google are sponsoring a prize for the first private group to send an unmanned rover to the Moon as a way of advancing these agendas; 22 teams have registered for the competition, with some scheduled to launch by the end of 2010. Increased attention to outer space travel, exploration, and commercial exploitation has been paralleled by a rise in interest in the protection of cultural resources on Earth, such as ar-chaeological sites and historic monuments. Such sites and monuments already exist in outer space and on extraterrestrial planetary bodies. The Apollo 11 landing site, Tranquility Base, is only the most obvious example of a cultural site of outstanding significance in space. Satellites orbiting the earth -even defunct ones such as Vanguard 1, the oldest man-made object still in orbit, might be considered to have extraordinary historic and cultural value, too. As archae-ologists working on Earth have long recognized, once a site or object is damaged, it can never be perfectly restored to its original condition. Unfortunately, there are so far only a few vague guidelines, drafted in the 1960's and agreed upon by the international community, protecting mankind's cultural heritage

    Sustainable maintenance and preservation of cultural heritage assets depends highly on its resilience to external or internal alterations and to various hazards. Risk assessment of a heritage asset's can be defined as the identification of all potential hazards affecting it and the evaluation of the asset's vulnerability (building materials and building structure conservation state).Potential hazards for cultural heritage are complex and varying. The risk of decay and damage associated with monuments is not limited to certain long term natural processes, sudden events and human impact (macroscale of the heritage asset) but is also a function of the degradation processes within materials and structural elements due to physical and chemical procedures. Obviously, these factors cover different scales of the problem. The deteriorating processes in materials may be triggered by external influences or caused because of internal chemical and/or physical variations of materials properties and characteristics. Therefore risk evaluation should be dealt in the direction of revealing the specific active decay and damage mechanism both in mesoscale [type of decay and damage] and microscale [decay phenomenon mechanism] level. A prerequisite for risk indicators identification and development is the existence of an organised source of comparable and interoperable data about heritage assets under observation. This unified source of information offers a knowledge based background of the asset's vulnerability through the diagnosis of building materials' and building structure's conservation state, through the identification of all potential hazards affecting these and through mapping of its possible alterations during its entire life-time. In this framework the identification and analysis of risks regarding degradation processes for the development of qualitative and quantitative indicators can be supported by documentation protocols. The data investigated by such protocols help

    This paper investigates the synergetic use of unmanned aerial vehicle (UAV) and terrestrial laser scanner (TLS) in 3D reconstruction of cultural heritage objects. Rather than capturing still images, the UAV that equips a consumer digital camera is used to collect dynamic videos to overcome its limited endurance capacity. Then, a set of 3D point-cloud is generated from video image sequences using the automated structure-from-motion (SfM) and patch-based multi-view stereo (PMVS) methods. The TLS is used to collect the information that beyond the reachability of UAV imaging e.g., partial building facades. A coarse to fine method is introduced to integrate the two sets of point clouds UAV image-reconstruction and TLS scanning for completed 3D reconstruction. For increased reliability, a variant of ICP algorithm is introduced using local terrain invariant regions in the combined designation. The experimental study is conducted in the Tulou culture heritage building in Fujian province, China, which is focused on one of the TuLou clusters built several hundred years ago. Results show a digital 3D model of the Tulou cluster with complete coverage and textural information. This paper demonstrates the usability of the proposed method for efficient 3D reconstruction of heritage object based on UAV video and TLS data.

  10. Ornaments in radiation treatment of cultural heritage: Color and UV-vis spectral changes in irradiated nacres

    Marušić, Katarina; Pucić, Irina; Desnica, Vladan

    2016-07-01

    Cultural heritage objects that are radiation treated in order to stop their biodegradation often contain ornamenting materials that cannot be removed. Radiation may produce unwanted changes to such materials. Nacre is a common ornamenting material so this is an attempt to assess the impact of gamma-radiation on its optical properties. Two types of nacre (yellow and white) were obtained from a museum and subjected to different absorbed doses of Co-60 gamma irradiation under the same conditions. The radiation induced changes of nacres color were investigated with fiber optic reflectance spectroscopy (FORS). Colorimetry in CIE Lab space revealed that in both nacres the lightness shifted to darker grey hues at high doses while the color component's (red, green, yellow and blue) behavior depended on the nacre type. Observable changes occurred at doses much above the dose range needed for radiation treatment of cultural heritage objects that are often ornamented with nacre. In UV-vis reflectance spectra of samples irradiated to high doses carbonate radical anion absorption appeared.

    2014-01-01

    The current literature often values intangible goods like cultural heritage by applying stated preference methods. In recent years, however, the increasing availability of large databases on real estate transactions and listed prices has opened up new research possibilities and has reduced various existing barriers to applications of conventional (spatial) hedonic analysis to the real estate market. The present paper provides one of the first applications using a spatial autoregressive model to investigate the impact of cultural heritage—in particular, listed buildings and historic-cultural sites (or historic landmarks)—on the value of real estate in cities. In addition, this paper suggests a novel way of specifying the spatial weight matrix—only prices of sold houses influence current price—in identifying the spatial dependency effects between sold properties. The empirical application in the present study concerns the Dutch urban area of Zaanstad, a historic area for which over a long period of more than 20 years detailed information on individual dwellings, and their market prices are available in a GIS context. In this paper, the effect of cultural heritage is analysed in three complementary ways. First, we measure the effect of a listed building on its market price in the relevant area concerned. Secondly, we investigate the value that listed heritage has on nearby property. And finally, we estimate the effect of historic-cultural sites on real estate prices. We find that, to purchase a listed building, buyers are willing to pay an additional 26.9 %, while surrounding houses are worth an extra 0.28 % for each additional listed building within a 50-m radius. Houses sold within a conservation area appear to gain a premium of 26.4 % which confirms the existence of a `historic ensemble' effect.

  12. Corrosion on cultural heritage buildings in Italy: a role for ozone?

    PubMed

    Screpanti, Augusto; De Marco, Alessandra

    2009-05-01

    Because of climatic reasons and of reduced concentrations of SO(2), ground-level ozone (O(3)) is one of the main air pollutants in Southern Europe. Ozone levels are very high both in rural and urban locations. In the cities, O(3) can affect human health and materials. Regarding materials, most relevant is the exposure to pollutants of cultural heritage buildings. In particular, monuments registered on UNESCO's list of the world heritage require special monitoring. In Italy 34% and 97% of the territory is exposed to corrosion risk higher than the tolerable level for limestone and copper, respectively. The tolerable corrosion level for limestone and copper was also exceeded in the central area of Milan. In this area the tolerable O(3) concentration for copper was calculated. These concentrations (ranging between 30 and 40 microg/m(3)) cannot be exceeded at unchanged concentration of other pollutants to maintain corrosion levels below the tolerable ones. PMID:19026474

  13. Erratic boulders in Switzerland, a geological and cultural heritage

    NASA Astrophysics Data System (ADS)

    Reynard, Emmanuel

    2015-04-01

    Erratic boulders are stones transported over quite long distances by glaciers and that differ from the type of rock upon which they rely. They range from the size of pebbles to large boulders weighing several thousand tons. Erratic boulders are significant geosites (Reynard, 2004) for several reasons. (1) First, they are indicators of former glacier extensions by marking glaciers' path, size and volume. In Switzerland, they allowed mapping the extension of large Alpine glaciers (the Rhine and Rhone glaciers, in particular) and their retreat stages (e.g. the Monthey erratic boulders that mark an important lateglacial stage of the Rhone glacier). Crystalline erratic boulders along the Jura range (limestone mountains) were used to map the altitude reached by the Rhone glacier during the two last glaciations. Precise mapping of crystalline and limestone boulders distribution also enabled mapping local Jura glaciers' recurrences after the Rhone glacier retreat. (2) During the last decades, several erratic boulders were used for cosmogenic nuclide exposure dating, which allowed impressive advances in palaeoclimatic research. (3) Erratic blocks have also an ecological interest by the fact that they "have transported" specific habitats in areas far away from their origin (e.g. acid crystalline rocks and soils in limestone areas such as in the Jura). For all these reasons, several erratic boulders were classified in the inventory of Swiss geosites. Erratic boulders also have a significant cultural value (Lugon et al., 2006). (1) The Glacier Garden in Lucerne was discovered in 1872. It comprises various surfaces of "roches moutonnées", potholes and large erratic blocks that document the presence of the Reuss glacier. Considered as a natural monument it is now one of the most famous touristic attraction of Lucerne and Central Switzerland. (2) The Pierre Bergère stone, situated in Salvan (Mont-Blanc massif, South-western Switzerland), is the place where future Nobel Prize

  14. Children's Everyday Learning by Assuming Responsibility for Others: Indigenous Practices as a Cultural Heritage Across Generations.

    Fernández, David Lorente

    2015-01-01

    This chapter uses a comparative approach to examine the maintenance of Indigenous practices related with Learning by Observing and Pitching In in two generations--parent generation and current child generation--in a Central Mexican Nahua community. In spite of cultural changes and the increase of Western schooling experience, these practices persist, to different degrees, as a Nahua cultural heritage with close historical relations to the key value of cuidado (stewardship). The chapter explores how children learn the value of cuidado in a variety of everyday activities, which include assuming responsibility in many social situations, primarily in cultivating corn, raising and protecting domestic animals, health practices, and participating in family ceremonial life. The chapter focuses on three main points: (1) Cuidado (assuming responsibility for), in the Nahua socio-cultural context, refers to the concepts of protection and "raising" as well as fostering other beings, whether humans, plants, or animals, to reach their potential and fulfill their development. (2) Children learn cuidado by contributing to family endeavors: They develop attention and self-motivation; they are capable of responsible actions; and they are able to transform participation to achieve the status of a competent member of local society. (3) This collaborative participation allows children to continue the cultural tradition and to preserve a Nahua heritage at a deeper level in a community in which Nahuatl language and dress have disappeared, and people do not identify themselves as Indigenous.

    Technology to document and investigate cultural heritage sites is rapidly advancing - multispectral and high dynamic range imaging, spherical high resolution photography, three-dimensional laser scanning and unmanned aerial vehicles are only a few of the new technologies available to heritage conservation professionals to record monuments, buildings, city centres and landscapes. These advanced tools are giving architects, engineers and conservation professionals' new insights and additional information which helps to make better informed decisions. But this technology and the knowledge about its correct use are extremely unevenly distributed across the world. The Digital Divide is present and growing in the field of cultural heritage preservation (Letellier, 2001). Many of those responsible for the management, maintenance and care of some of the world's most significant cultural heritage sites do not have access to or information about the latest technologies. They are also confronted with an overwhelming assortment of new technologies and consultants or developers that promote them and therefore must allocate their limited budgets with limited information. What is to be done about bridging this gap? Obviously cost and accessibility are issues. However one of the most important challenges to be addressed is education. As the base knowledge of these technologies is very uneven this leads to further questions: Are there strategies or methodologies for teaching this technology? How to combine and balance different professional backgrounds from different and so unevenly distributed places around the world and provide them all with useful information to make good documentation and conservation decisions? This paper will describe the methodology developed over the last ten years in teaching documentation technologies to diverse groups of cultural heritage professionals and students from Côte d'Ivoire, Germany, Belgium, Kosovo, Albania, Nigeria, Egypt, Japan, Iraq

    Archaeometry is an area established in the international community since the 60s, with extensive use of atomic-nuclear methods in the characterization of art, archaeological and cultural heritage objects in general. In Brazil, however, until the early '90s, employing methods of physics, only the area of archaeological dating was implemented. It was only after this period that Brazilian groups became involved in the characterization of archaeological and art objects with these methodologies. The Laboratory of Applied Nuclear Physics, State University of Londrina (LFNA/UEL) introduced, pioneered in 1994, Archaeometry and related issues among its priority lines of research, after a member of LFNA has been involved in 1992 with the possibilities of tomography in archaeometry, as well as the analysis of ancient bronzes by EDXRF. Since then, LFNA has been working with PXRF and Portable Raman in several museums in Brazil, in field studies of cave paintings and in the laboratory with material sent by archaeologists, as well as carrying out collaborative work with new groups that followed in this area. From 2003/2004 LAMFI/DFN/IFUSP and LIN/COPPE/UFRJ began to engage in the area, respectively with methodologies using ion beams and PXRF, then over time incorporating other techniques, followed later by other groups. Due to the growing number of laboratories and institutions/archaeologists/conservators interested in these applications, in may 2012 was created a network of available laboratories, based at http://www.dfn.if.usp.br/lapac. It will be presented a panel of recent developments and applications of these methodologies by national groups, as well as a sampling of what has been done by leading groups abroad.

    2015-08-01

    In Thailand, there are several types of (tangible) cultural heritages. This work focuses on 3D modeling of the heritage objects from multi-views images. The images are acquired by using a DSLR camera which costs around 1,500 (camera and lens). Comparing with a 3D laser scanner, the camera is cheaper and lighter than the 3D scanner. Hence, the camera is available for public users and convenient for accessing narrow areas. The acquired images consist of various sculptures and architectures in Wat-Pho which is a Buddhist temple located behind the Grand Palace (Bangkok, Thailand). Wat-Pho is known as temple of the reclining Buddha and the birthplace of traditional Thai massage. To compute the 3D models, a diagram is separated into following steps; Data acquisition, Image matching, Image calibration and orientation, Dense matching and Point cloud processing. For the initial work, small heritages less than 3 meters height are considered for the experimental results. A set of multi-views images of an interested object is used as input data for 3D modeling. In our experiments, 3D models are obtained from MICMAC (open source) software developed by IGN, France. The output of 3D models will be represented by using standard formats of 3D point clouds and triangulated surfaces such as .ply, .off, .obj, etc. To compute for the efficient 3D models, post-processing techniques are required for the final results e.g. noise reduction, surface simplification and reconstruction. The reconstructed 3D models can be provided for public access such as website, DVD, printed materials. The high accurate 3D models can also be used as reference data of the heritage objects that must be restored due to deterioration of a lifetime, natural disasters, etc.

    Kuqa, Xinjiang, is located at northwestern inland china. Traditionally a bridge between eastern and western civilizations, Kuqa had a history of cultural fusion and was left with abundant cultural heritage. As population increase, economic growth and social changes occurred, spontaneous renovation of the old city was affected, in which street fabric and scenes underwent damages. The paper demonstrates attempts made in various projects to achieve conservation of cultural heritage in agreement with economic development and improvement of living condition. The lessons learnt in these projects will be of value to development of other historic cities, especially in minority ethnic regions in China.

    The laser-induced breakdown spectroscopy (LIBS) is an applied physical technique that has shown in recent years its great potential for rapid qualitative analysis of materials. Thanks to the possibility to implement a portable instrument that perform LIBS analysis, this technique is revealed to be particularly useful for in situ analysis in the field of cultural heritages. The purpose of this work is to evaluate the potentiality of LIBS technique in the field of cultural heritages, with respect to the chemical characterization of complex matrix as calcareous and refractory materials for further quantitative analyses on cultural heritages. X-Ray Fluorescence (XRF) analyses were used as reference. Calibration curves of certified materials used as standards were obtained by XRF analyses. The LIBS measurements were performed with a new mobile instrument called Modì (Mobile Double pulse Instrument for LIBS Analysis). The XRF analyses were performed with a portable instrument ArtTAX. LIBS and XRF measurement were performed on both reference materials and samples (bricks and mortars) sampled in the ancient Greek-Roman Theatre of Taormina. Although LIBS measurements performed on reference materials have shown non linear response to concentrations, and so we were not able to obtain quantitative results, an integrated study of XRF and LIBS signals permitted us to distinguish among chemical features and degradation state of measured building materials.

    Applications of time-resolved photoluminescence spectroscopy (TRPL) and fluorescence lifetime imaging (FLIM) to the analysis of cultural heritage are presented. Examples range from historic wall paintings and stone sculptures to 20th century iconic design objects. A detailed description of the instrumentation developed and employed for analysis in the laboratory or in situ is given. Both instruments rely on a pulsed laser source coupled to a gated detection system, but differ in the type of information they provide. Applications of FLIM to the analysis of model samples and for the in-situ monitoring of works of art range from the analysis of organic materials and pigments in wall paintings, the detection of trace organic substances on stone sculptures, to the mapping of luminescence in late 19th century paintings. TRPL and FLIM are employed as sensors for the detection of the degradation of design objects made in plastic. Applications and avenues for future research are suggested. PMID:24699285

  5. The historical and cultural heritage from Brazil: rocks and deterioration patterns

    2014-05-01

    This summary provides information on the results of a research in progress, which focuses on the investigation of stone materials, as steatites, serpentinites, quartzites and schists, widely used in construction of buildings belonging to the cultural heritage of Brazil, especially in those that are in the state of Minas Gerais. These historic buildings, some of those with more than three hundred years of existence and constructed with the use of different rocks, function as open-air laboratories and because of that assists on the study of the deterioration of these materials. In its early stages, the research has focused on macroscopic characterization of the employed materials, following with the lifting of their respective areas of occurrence. Then samples for the survey of other features, such as its chemical and physical-mechanical properties were collected. The investigated physical-mechanical properties were as follows: thermal dilatation coefficient, compressive and flexural strength, abrasion resistance, water absorption coefficient by capillarity, real and apparent density, total and open porosity. Currently, the research focuses on issues such as: evidence of degradation and extent of deterioration in these monuments, as a result of the performance of different processes of alteration and decay. In this investigation it is understood that the first processes are associated with modifications of stone materials, which do not necessarily imply in worsening of the characteristics of these materials from the point of view of conservation and seconds are related to chemical and physical changes of intrinsic properties of rocks used in the construction of this heritage, which can lead to a loss of value, or some impediment of use, according to the indications of the illustrated glossary on patterns of deterioration of rocks proposed by ICOMOS. For this purpose macroscopic descriptions of monuments and its applied rocks, accompanied by detailed photographic

    For bicultural individuals, visual cues of a setting’s cultural expectations can activate associated representations, switching the frames that guide their judgments. Research suggests that cultural cues may affect judgments through automatic priming, but has yet to investigate consequences for linguistic performance. The present studies investigate the proposal that heritage-culture cues hinder immigrants’ second-language processing by priming first-language structures. For Chinese immigrants in the United States, speaking to a Chinese (vs. Caucasian) face reduced their English fluency, but at the same time increased their social comfort, effects that did not occur for a comparison group of European Americans (study 1). Similarly, exposure to iconic symbols of Chinese (vs. American) culture hindered Chinese immigrants’ English fluency, when speaking about both culture-laden and culture-neutral topics (study 2). Finally, in both recognition (study 3) and naming tasks (study 4), Chinese icon priming increased accessibility of anomalous literal translations, indicating the intrusion of Chinese lexical structures into English processing. We discuss conceptual implications for the automaticity and adaptiveness of cultural priming and practical implications for immigrant acculturation and second-language learning. PMID:23776218

    Cultural heritage landscapes are consistently perceived as landscapes of high value. However, these landscapes are very vulnerable to change. In China, rapid land use change, especially urbanization, has become one of the main challenges for the conservation of cultural heritage landscapes in rural areas. This paper focuses on the designated cultural villages in rural China by systematically analyzing the spatial distribution of the designated cultural landscape across the country and assessing the threats these traditional landscapes are facing under current and future urbanization and other land use pressures. Current designated cultural heritage landscapes in China are predominantly located in the rural and peri-urban regions of Central and South China and less frequently found in other regions. Especially in these regions risks to land use change are large. These risks are assessed based on observed recent land use change and land use model simulations for scenarios up to 2050. The risk assessment reveals that especially in Southeast China along the sea coast and near the cities along the Yangtze River, high pressures are expected on cultural heritage landscapes due to urbanization. At the same time, in Southwest China, especially in Yunnan and Guizhou provinces, high pressures due to other land use changes are expected, including land abandonment. This assessment gives direction and guidance toward the selection of the most threatened cultural villages for detailed investigation and additional protection measures.

    As the 500th anniversary of European arrival in Brazil approached in the year 2000, it provided a stimulus for the country to review the cultural and economic significance of its remaining colonial built heritage. This is not least because of the growing awareness that built heritage is an important attractor for high income tourism and an increasing willingness amongst the population at large to accept colonial artefacts as a legitimate component of national history. Nowhere is this revision more apposite than in the adjacent cities of Rio de Janeiro and Niteroi. In both cities much of the colonial heritage was swept away during the late twentieth century in a tide of reconstruction that was symbolic of self-proclaimed Brazilian modernity and that signified for many a break with their colonial past. Those elements of colonial heritage that have survived have done so largely because of their ownership either by the church or the military. However, whilst this has often protected the overall building, the detailed fabric of such structures has at best been neglected and in many cases abused. As a consequence, stonework, in particular, can exhibit a range of decay features that must be addressed if this heritage is to be preserved and its educational and economic potential realised. In this presentation, we review changing attitudes towards conservation as illustrated by a number of key structures, including the large stone forts that guard the entrance to Guanabara Bay. This is combined with a detailed examination of threats to the integrity of their stonework consequent on prolonged exposure in a humid tropical maritime environment. Most of these structures are built of local, very durable augen gneiss. However, studies of natural rock outcrops show that this rock does weather, and that breakdown can be episodic as localised strength thresholds are breached. Surveys suggest that some buildings may be approaching such threshold conditions, whereby stresses

    Syria is a country of many civilizations, Marie, Aramaic, Phoenician, Roman, Byzantine, Islamic, Ottoman civilizations. Unfortunally the recent war is the reason for many cultural heritage items to be destroyed, beyond the thausand civilian people killed. In 2010, just before the war, the A. made a touristic trip together with Crua (Recreational Club of the Ancona University). It was the occasion to make some fast documentation of some Syrian CH monuments. Mostly of the images were taken by the A. not to make a survey, but as a photographic report, as fast and complete as possible. For a regular survey project, the tripod, the spherical head should be used for the takings and the 3x3 Cipa rules should be followed, that occurred only in the three main projects, say the survey of the citadel walls in Aleppo, the survey of the Umayyads Mosque in Damascus, and the survey of the minaret of the Umayyads Mosque in Aleppo. All the other documentation surveys have been carried out with hand-held camera taking the dimension of the model from Google earth high resolution, when available. But, apart the regular surveys, due to the explosion of the unexpected war, the photographs taken in such a touristic way, have been used to try to get some usable plottings an restitutions and it worked successfully mostly of the times. These surveys could be useful in case of reconstruction and in case of lack of suitable alternative metric documentation. Because of the continuing threats, all six Syrian World Heritage properties were inscribed on the List of World Heritage in Danger, at the 37th session of the World Heritage Committee, held in Cambodia last June: Ancient City of Aleppo, Ancient City of Bosra, Ancient City of Damascus, Ancient Villages of Northern Syria, Krak des Chevaliers and Qal'at Salah El-Din ans finally the Site of Palmyra.

He explained that CHARISMA was for people working in Europe (or in associated countries). There was some discussion then about the need for a similar sort of network being established for the Middle East region. The proceedings contain peer reviewed papers presented at the conference. During the conference and in collaboration with the Sharjah Department of Culture and Information (Directorate of Antiquities), the American University of Sharjah organized an archaeology exhibition from the 30 November until the 10 December 2011. Special thanks go to Dr Sabah Jasim and Eisa Abbas from the Sharjah Directorate of Antiquities for facilitating this event. The exhibition included about 45 artifacts from different sites within Sharjah emirate, some of which dated as far back 7000 years ago. These artifacts included: flint arrowheads, pottery and alabaster vessels, metal objects including bronze arrowheads and coins, as well as carnelian bead necklaces. Also coinciding with the XTACH11 conference, the American University of Sharjah, in cooperation with The International Atomic Energy Agency (IAEA) and the National X-ray Fluorescence Laboratory organized a regional training course from 3-8 December 2011. This covered a similar range of topics to those discussed at the XTACH11 conference. Participants of the course were trained in the use of physical and analytical techniques in cultural heritage. In addition to lectures from the National X-ray Fluorescence Laboratory and from the IAEA, the NXFL team provided the opportunity for trainees to undertake projects on ancient pottery samples, metal artifacts and Islamic manuscripts. The practical part of the course included experiments on XRF (portable, and micro XRF

    Photogrammetrey has a long successful history in the area of 3D modelling and documentation of cultural heritage monuments. In some cases an extensive study, preparation and the application of novel solutions is required for the successful documentation and 3D modelling of monuments. In most of the cases the problem that we have to face is difficulties regarding accessing, photographing, and measuring the monument from the optimal distance, in combination with the need for a high spatial resolution mapping. This paper is highlighting the special problems and the novel solutions, performed during mapping of two significant cultural heritage monuments in Greece. The Roussanou monastery (1527-1529 A.C., Meteora, Center Greece) and its underlying rock, had to be photographed and measured from a far distance and measured with various spatial resolutions. In the lakeside Neolithic settlement of Dispilio (6.000 B.C., western Greece) the enclosure which is covered with vegetation above a height of 3 m, had to be measured with high spatial resolution. The combined use of a laser scanner, a digital camera equipped with a telephoto lens and UAV allowed the successful mapping and the production of orthophotomaps in each case.

  13. The protective and detrimental effects of self-construal on perceived rejection from heritage culture members

    Individuals may perceive themselves as interdependent and similar with close others, or as independent and distinct. Do these differences in self-construal influence perceptions of rejection from those closest to us? Few studies have investigated the antecedents of intragroup marginalization – the perception of rejection from family and friends due to not conforming to the prescribed values and expectations of one’s heritage culture. Furthermore, the implications of perceived intragroup marginalization for psychological adjustment and an integrated bicultural identity are unclear. To gage the effects of self-construals on perceived intragroup marginalization and psychological adjustment (i.e., subjective well-being and flourishing) and an integrated bicultural identity, we increased the cognitive accessibility of independent and interdependent self-construals through a priming manipulation. Participants were recruited via Amazon MTurk and completed the measures online. Our results showed that priming an interdependent self-construal decreased perceived intragroup marginalization from family and, in turn, poor psychological adjustment and bicultural identity conflict. Conversely, participants primed with an independent self-construal reported increased perceptions of intragroup marginalization from their family and, in turn, decreased psychological adjustment and increased identity conflict. These findings support the benefits of an interdependent self and the disadvantages of an independent self for minimizing perceived exclusion from heritage culture members. PMID:25762950

    Cultural Heritage preventive conservation requires the monitoring of the parameters involved in the process of deterioration of artworks. Thus, both long-term monitoring of the environmental parameters as well as further analysis of the recorded data are necessary. The long-term monitoring at frequencies higher than 1 data point/day generates large volumes of data that are difficult to store, manage and analyze. This paper presents software which uses a free open source database engine that allows managing and interacting with huge amounts of data from environmental monitoring of cultural heritage sites. It is of simple operation and offers multiple capabilities, such as detection of anomalous data, inquiries, graph plotting and mean trajectories. It is also possible to export the data to a spreadsheet for analyses with more advanced statistical methods (principal component analysis, ANOVA, linear regression, etc.). This paper also deals with a practical application developed for the Renaissance frescoes of the Cathedral of Valencia. The results suggest infiltration of rainwater in the vault and weekly relative humidity changes related with the religious service schedules. PMID:23447005

    National Geoparks initiatives are essential strategies to enhance the value of Earth's heritage and to promote a regional sustainable socio-economic and cultural development. As an example for geological heritage development, an ongoing partnership between the Department of Geological and Environmental Sciences of the University of Bologna (Italy) and the Office Nationales des Mines (Tunisia) attempt to ensure divulgation and preservation of the geological, geomorphological and archeological values of the Tataouine region in South Tunisia, with the final goal to create a Geopark. In this region, different environmental and cultural heritages that comprehend paleontology, geomorphology, stratigraphy and archeology coexist. Mesozoic beds that crop out extensively in the Tataouine region known since the beginning of the 20th century as Continental Intercalaire, yield numerous dinosaur and other vertebrate remains as well as tracksites. Moreover these Mesozoic deposits have been intensively modified for centuries by the local populations who created complex systems of artificial terraces, called jessour, in order to retain rainwater in the arid Tunisian climate and to exploit the scarce farm soil. These human artifacts deeply modified the morphological and hydrogeological landscape and created a unique cultural value that need to be preserved. From the perspective of science and conservation, a well-documented geological inventory of the fossiliferous sites has been produced and will be available as an electronic database. In particular, the Beni Ghedir valley, near the Goumrassene village, has been chosen has the main Geopark location as it includes, in a restricted area, a perfect example of jessour artifacts together with some well-preserved Ksour (ancient storage structures) and nicely preserved fossil sites. An interactive map of the artificial terrances has been produced using the ArcGis technology, in order to highlight the connection between the valley

    This project belongs to a specific work aiming at developing isotopic tools to better understand the alteration of materials used in the built cultural heritage. It is focused on the study of the alteration of limestone used in the facades of historic buildings subject to atmospheric polluted environment. Actually in the elevated parts of the buildings, water as rainfall (runoff or wet deposition) or in vapor form (condensation or dry deposition) is the main agent of alteration. Thus, the rock/water interactions need to be well understood to propose adapted solution to better preserve the buildings. To identify the water transfer within the porous limestone and locate the reaction preferential sites, two isotopic tracers (D and 18O) are used to monitor the alteration solution (D) and locate the zones containing the secondary phases (18O). The Saint-Maximin limestone used in many monuments in the suburbs of Paris (France) as a building and restoration stone has been specifically studied. Pristine materials, stones from monuments (monuments in the Paris area) and samples altered in laboratory constitute the analytical corpus to compare different stages of alteration. In a first step the stones are characterized at different scales to identify the alteration pattern (SEM-EDS, Raman microspectrometry, XRD, rugosimetry) and study the water transfers (X-ray tomography, mercury porosimetry, imbibition kinetics). The samples are then altered in the laboratory by realistic and controlled wet or dry deposition using isotopically labeled solutions to locate the reaction zones by SIMS. The multiscale characterization of the alteration pattern has allowed proposing alteration mechanisms linked to the properties of the stones and their location inside the building. Moreover, the location of the reactive zones inside the materials determined by the isotopic experiments helps examining the role of the evolution of porosity and formation of alteration products within the material

    The paper describes reading criteria for an analysis and interpretation of material systems in relation to a built space, survey guidelines and its reading criteria for Cultural Heritage (CH) values'monitoring and transmission. In addition, integrated systems of digital technologies and 2D/3D digitization of CH are introduced for an effective and accurate reading of Venice and Milan's monuments. Specifically, the guidelines for an architectural survey allow to organize and document historic monuments information, and to identify the significant cultural/physical elements of our past in order for them to be preserved and protected for future generations. In addition, in this paper the studied projects introduce a combination of virtual technologies and historical reality with experimenting innovative solutions for CH. From the methodological point of view, this study has made use of the identification of levels of study (LS) differentiated, each of which is capable of identifying categories.

    Under the influence of global climate change, the risk preparedness has become a universal issue in different research fields. In the conservation of cultural heritage, disaster risk management is becoming one of the major research topics. Besides researches on the theory and mechanism of disaster risk management, the tools for the performance of site managers to protect cultural heritage is another important issue that needs development. UNESCO and ICOMOS have released some important documents on disaster risk management including its concept, identification, evaluation, mitigation, monitoring and resilience, etc. However, there is a big gap between concept and implementation in Taiwan. Presently there are 2000 monuments in Taiwan that hardly meet the modern code. First, based on international documents released, this research presents 13 disaster indicators on monuments and their environments. Next, 345 monuments in northern Taiwan are taken as examples to evaluate their risk situations with indicators designed in 2011. Some positive recommendations were given at the same time. As a result, a comparative evaluation was completed in 2012 and some key issues are found, such as too many electrical facilities, lack of efficient firefighting equipment, and a shortage of management mechanism, just to name a few. Through the improvement of the management, some major risk can be mitigated. In 2013~14, this research took 23 national monuments from the 345 monuments to evaluate their risk situations and compare the differences between national and local monuments. Results show that almost all management mechanisms in the national monuments have been established and are running well. However, problems like inappropriate electrical facilities and insufficient monitoring equipment remain. In addition, the performance of private monuments is not as good as public ones. Based on the collected information and evaluation, this research develops safety measures of heritage

    Documentation of the cultural heritage sites is extremely important for monitoring and preserves them from natural disasters and human made activities. Due to its very rich historical background from the first human settlements in Catalhoyuk and Alacahoyuk and civilizations such as Byzantine, Seljuk and Ottoman, there are lots of cultural heritage sites in Turkey. 3D modeling and recording of historical buildings using modern tools and techniques in several locations of Turkey have been conducted and still continuing. The nine cultural sites in Turkey are included in the protection list of UNESCO as cultural heritage and one of them is the township of Safranbolu, which is the one of the most outstanding example of the traditional Turkish Architecture and also unique itself in terms of conservation of the human settlement in their authentic environmental motif up till now. In this study outcomes and further studies of a research project related to study area which is supported by the Turkish National Research Center (TUBITAK) with the project number 106Y157, will be presented in details. The basic aim of the study is development a GIS based information and management system for the city of Safranbolu. All historical buildings which are registered are assigned with the database. 3D modeling some of the selected building among the buildings which are registered as historical monuments using different data comes from different sources similar to their original constructions were realized and then it will be distributed via internet by a web-based information system designed during the project. Also some of the buildings were evaluated using close range photogrammetric technique to obtain their façade reliefs, were also assigned with the database. Designed database consists of 3D models, locations, historical information, cadastral and land register data of the selected buildings together with the other data collected during the project related to buildings.

    The paper aims to highlight the unique integration of natural and cultural heritage within the Dwejra area, a site of outstanding scenery located along the NW coast of the Island of Gozo (Malta). Dwejra displays a great variety of geological and geomorphological features as well as unusual and unique ecological systems, concentrated in a relatively small and remoteness area. The landscape is made of a large set of landforms created by several processes: karst dissolution, forming at least four solution subsidence structures in the area; fluvial processes (marked by the presence of perennial freshwater pools), seepage from cliffs, waterfall and several dry valley systems (widien); marine erosion processes as evidenced by the great variety of features, including with sea-caves, tunnel, arches, stacks and reefs. The presence of cultural features spanning from rubble walls and rural structures, to cart-ruts of unknown age and structures of the 19th Century enrich the interest in the area and allow it to become a landmark of cultural importance to the history of the island as a whole. This unique combination of geological l.s., cultural and biological heritage contributes in making Dwejra a site of extraordinary scientific importance and heritage value, an ideal tourist destination for fostering a varied form of geotourism. In perspective of tourism promotion and geoconservation measures, this paper aims at highlighting how the integration of environmental and cultural heritage aspects makes the Dwejra area a site of remarkable value to be promoted for a more holistic and varied tourism.

    The logistics and cost of environmental monitoring can represent challenges for heritage managers, partly because of the sheer number of environmental parameters to consider. There is a need for a system, capable of monitoring the holistic impact of the environment on cultural materials while remaining relatively easy to use and providing remote access. This paper describes a dosimetric system based on piezoelectric quartz crystal technology. The prototype sensing module consists of an array of piezoelectric quartz crystals (PQC) coated with different metals (Fe, Cu, Ni and Sn) and includes a temperature and relative humidity sensor. The communication module involves an 802.15.4 low-power radio and a GPRS gateway which allows real time visualisation of the measurements online. An energy management protocol ensures that the system consumes very low power between measurements. The paper also describes the results and experiences from two heritage field deployments, at Apsley House in London, UK, and at the Royal Palaces of Abomey in Benin. Evaluation of PQC measurements, temperature, relative humidity and the rate of successful transmission over the communication systems are also reported. PMID:24854056

    Deriving from the complex nature of cultural heritage conservation it is the need for enhancing a systematic but flexible organization of expert knowledge in the field. Such organization should address comprehensively the interrelations and complementariness among the different factors that come into play in the understanding of diagnostic and intervention problems. The purpose of MONDIS is to endorse this kind of organization. The approach consists in applying an ontological representation to the field of heritage conservation in order to establish an appropriate processing of data. The system allows replicating in a computer readable form the basic dependence among factors influencing the description, diagnosis and intervention of damages to immovable objects. More specifically MONDIS allows to input and search entries concerning object description, structural evolution, location characteristics and risk, component, material properties, surveys and measurements, damage typology, damage triggering events and possible interventions. The system supports searching features typical of standard databases, as it allows for the digitalization of a wide range of information including professional reports, books, articles and scientific papers. It also allows for computer aided retrieval of information tailored to user's requirements. The foreseen outputs will include a web user interface and a mobile application for visual inspection purposes.

    The majority of human activities are concentrated around coastal areas, making coastline retreat, a significant threat to coastal infrastructure, thus increasing protection cost and investment revenue losses. In this study the management of coastal areas in terms of protecting coastal infrastructures, cultural and environmental heritage sites, through risk assessment analysis is been made. The scope is to provide data for spatial planning for future developments in the coastal zone and the protection of existing ones. Also to determine the impact of coastal changes related to the loss of natural resources, agricultural land and beaches. The analysis is based on a multidisciplinary approach, combining environmental, spatial and economic data. This can be implemented by integrating the assessment of vulnerability of coasts, the spatial distribution and structural elements of coastal infrastructure (transport, tourism, and energy) and financial data by region, in a spatial database. The approach is based on coastal vulnerability estimations, considering sea level rise, land loss, extreme events, safety, adaptability and resilience of infrastructure and natural sites. It is based on coupling of environmental indicators and econometric models to determine the socio-economic impact in coastal infrastructure, cultural and environmental heritage sites. The indicators include variables like the coastal geomorphology; coastal slope; relative sea-level rise rate; shoreline erosion/accretion rate; mean tidal range and mean wave height. The anthropogenic factors include variables like settlements, sites of cultural heritage, transport networks, land uses, significance of infrastructure (e.g. military, power plans) and economic activities. The analysis in performed by a GIS application. The forcing variables are determined with the use of sub-indices related to coastal geomorphology, climate and wave variables and the socioeconomics of the coastal zone. The Greek coastline in

    Nowadays, there are rapid developments in the fields of photogrammetry, laser scanning, computer vision and robotics, together aiming to provide highly accurate 3D data that is useful for various applications. In recent years, various LiDAR and image-based techniques have been investigated for 3D modelling because of their opportunities for fast and accurate model generation. For cultural heritage preservation and the representation of objects that are important for tourism and their interactive visualization, 3D models are highly effective and intuitive for present-day users who have stringent requirements and high expectations. Depending on the complexity of the objects for the specific case, various technological methods can be applied. The selected objects in this particular research are located in Bulgaria - a country with thousands of years of history and cultural heritage dating back to ancient civilizations. This motivates the preservation, visualisation and recreation of undoubtedly valuable historical and architectural objects and places, which has always been a serious challenge for specialists in the field of cultural heritage. In the present research, comparative analyses regarding principles and technological processes needed for 3D modelling and visualization are presented. The recent problems, efforts and developments in interactive representation of precious objects and places in Bulgaria are presented. Three technologies based on real projects are described: (1) image-based modelling using a non-metric hand-held camera; (2) 3D visualization based on spherical panoramic images; (3) and 3D geometric and photorealistic modelling based on architectural CAD drawings. Their suitability for web-based visualization are demonstrated and compared. Moreover the possibilities for integration with additional information such as interactive maps, satellite imagery, sound, video and specific information for the objects are described.

    The development of the Qatar National Historic Environment Record (QNHER) by the Qatar Museums Authority and the University of Birmingham in 2008 was based on a customised, bilingual Access database and ArcGIS. While both platforms are stable and well supported, neither was designed for the documentation and retrieval of cultural heritage data. As a result it was decided to develop a custom application using Open Source code. The core module of this application is now completed and is orientated towards the storage and retrieval of geospatial heritage data for the curation of heritage assets. Based on MIDAS Heritage data standards and regionally relevant thesauri, it is a truly bilingual system. Significant attention has been paid to the user interface, which is userfriendly and intuitive. Based on a suite of web services and accessed through a web browser, the system makes full use of internet resources such as Google Maps and Bing Maps. The application avoids long term vendor ''tie-ins'' and as a fully integrated data management system, is now an important tool for both cultural resource managers and heritage researchers in Qatar.

    Black crusts are recognized to have been, up to now, one of the major deterioration forms affecting the built heritage in urban areas. Their formation is demonstrated to occur mainly on carbonate building materials, whose interaction with an SO2-loaded atmosphere leads to the transformation of calcium carbonate (calcite) into calcium sulfate dihydrate (gypsum) which, together with embedded carbonaceous particles, consequently forms the black crusts on the stone surface. An analytical study was carried out on black crust samples collected from limestone monumental buildings and churches belonging to the European built Heritage, i.e., the Corner Palace in Venice (Italy), the Cathedral of St. Rombouts in Mechelen (Belgium), and the Church of St. Eustache in Paris (France). For a complete characterization of the black crusts, an approach integrating different and complementary techniques was used, including laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), Fourier transform infrared spectroscopy, optical and scanning electron microscopy. In particular, the application of LA-ICP-MS permitted to obtain a complete geochemical characterization in terms of trace elements of the black crusts from the inner parts to the external layers contributing to the identification of the major combustion sources responsible for the deterioration over time of the monuments under study. In addition, the obtained results revealed a relation between the height of sampling and the concentration of heavy metals and proved that the crust composition can be a marker to evaluate the variation of the fuels used over time.

    Transracial adoptees represent a specific group of immigrants who experience unique immigration processes that bring them face-to-face with two cultural backgrounds: that of their heritage culture on one hand and that of their national culture on the other hand. However, there is a scarcity of studies focused on the way these processes unfold within adoptive families. This study was aimed at exploring how transracial adoptees cope with the construction of their ethnic identity. Administering a self-report questionnaire to 127 transracial adoptees and their mothers, for a total of 254 participants, we first investigated the association between mothers' cultural socialisation (enculturation and preparation for bias strategies) and adoptees' ethnic identity (i.e. ethnic identity exploration and ethnic identity affirmation dimensions). We then investigated whether ethnic identity affects self-esteem by testing the hypothesis that national identity moderates the relationship between ethnic identity and self-esteem. Results revealed that mothers' enculturation (but not their preparation for bias) supported adoptees' ethnic identity exploration, which in turn was positively associated with ethnic identity affirmation. Moreover, we confirmed the moderation effect: ethnic identity affirmation enhanced the level of self-esteem, but only for those adoptees who perceived a higher degree of national identity affirmation.

    Conservation of historical buildings is an important issue and the environmental conditions seriously affect the monument's stones. The protection of cultural heritage buildings and monuments by surface treatment with polymers is a common practice due to their ability to form a protective layer on the monument's surface as well as to control the transport of different fluids from the surface to the monument's interior. In this work, three different substrates were used: Carrara marble, Botticino limestone, and Angera stone. A commercially available Si-based resin (Alpha®SI30) was used as protective agent to improve the hydrophobicity features of the different tested materials. The surface properties of the coating and the relative interaction with the adopted stones were studied using different techniques such as contact angle measurements, electron microscope coupled with an energy dispersive spectrometer, X-ray photoelectron spectroscopy, atomic force microscopy, and attenuated total reflection infrared spectroscopy.

    In order to analyze the potential as well as the limitations of low-cost RPAS photogrammetric systems for architectural cultural heritage reconstruction, some tests were performed by a small RPAS equipped with an ultralight camera. The tests were carried out in a site of remarkable historical interest. A great amount of images were taken with camera's optical axis in vertical and oblique position. Images were processed by the commercial software PhotoScan of Agisoft and numerous models were realized, each of them was compared with an accurate TLS model used as a reference. The test, despite some problems found, has provided good results in terms of accuracy (average error <2cm) and reliability.

    The analytical study of Cultural Heritage objects often requires merely a qualitative determination of composition and manufacturing technology. However, sometimes a qualitative estimate is not sufficient, for example when dealing with multilayered metallic objects. Under such circumstances a quantitative estimate of the chemical contents of each layer is sometimes required in order to determine the technology that was used to produce the object. A quantitative analysis is often complicated by the surface state: roughness, corrosion, incrustations that remain even after restoration, due to efforts to preserve the patina. Furthermore, restorers will often add a protective layer on the surface. In all these cases standard quantitative methods such as the fundamental parameter based approaches are generally not applicable. An alternative approach is presented based on the use of Monte Carlo simulations for quantitative estimation.

    A new acquisition system for remote control of wall paintings has been realized and tested in the field. The system measures temperature and atmospheric pressure in an archeological site where a fresco has been put under control. The measuring chain has been designed to be used in unfavorable environments where neither electric power nor telecommunication infrastructures are available. The environmental parameters obtained from the local monitoring are then transferred remotely allowing an easier management by experts in the field of conservation of cultural heritage. The local acquisition system uses an electronic card based on microcontrollers and sends the data to a central unit realized with a Raspberry-Pi. The latter manages a high quality camera to pick up pictures of the fresco. Finally, to realize the remote control at a site not reached by internet signals, a WiMAX connection based on different communication technologies such as WiMAX, Ethernet, GPRS and Satellite, has been set up.

    Serendipity and experiment have been a frequent approach for the development of materials and methodologies used for a long time for either cleaning or consolidation of works of art. Recently, new perspectives have been opened by the application of materials science, colloid science, and interface science frameworks to conservation, generating a breakthrough in the development of innovative tools for the conservation and preservation of cultural heritage. This Article is an overview of the most recent contributions of colloid and materials science to the art conservation field, mainly focusing on the use of amphiphile-based fluids, gels, and alkaline earth metal hydroxide nanoparticles dispersions for the cleaning of pictorial surfaces, the consolidation of artistic substrates, and the deacidification of paper, canvas, and wood. Future possible directions for solving several conservation issues that still need to be faced are also highlighted. PMID:23432390

    One of the most important aspects of documenting cultural heritage sites is acquiring detailed and accurate data. A popular method of storing 3D information about historical structures is using 3D models. These models are built based on terrestrial or aerial laser scanning data. These methods are seldom used together. Historical buildings usually have a very complex design, therefore the input data, on the basis of which their 3D models are being built, must provide a high enough accuracy to model these complexities. The data processing methods used, as well as the modeling algorithms implemented, should be highly automated and universal. The main of the presented research was to analyze and compare various methods for extracting matching points. The article presents the results of combining data from ALS and TLS using reference points extracted both manually and automatically. Finally, the publication also includes an analysis of the accuracy of the data merging process.

It has been interested a territory strip including the initial well known route of Tratturo Regio, an ancient pastoral passage of transhumance from high rough grazing of Abruzzo to the largest plains of northern Puglia (Tavoliere). This area has a particularly well preserved environment, very rich in archaeological remains for any chronological period. The study has been realized by direct survey, going through documents in different archives, examination of historical and modern aerial photograph. The outcome of research is a view of ancient occupation of the area, from prehistorical to medieval period. Through the analisys (or reading) of historical and present photos have been identified and localized (geographical positioning) a large amount of cropmarks concerning new sites at most (settlements, necropolis, roads, single structures, etc.).

    This paper proposes to use deep learning to improve semi-automatic mapping of cultural heritage from airborne laser scanning (ALS) data. Automatic detection methods, based on traditional pattern recognition, have been applied in a number of cultural heritage mapping projects in Norway for the past five years. Automatic detection of pits and heaps have been combined with visual interpretation of the ALS data for the mapping of deer hunting systems, iron production sites, grave mounds and charcoal kilns. However, the performance of the automatic detection methods varies substantially between ALS datasets. For the mapping of deer hunting systems on flat gravel and sand sediment deposits, the automatic detection results were almost perfect. However, some false detections appeared in the terrain outside of the sediment deposits. These could be explained by other pit-like landscape features, like parts of river courses, spaces between boulders, and modern terrain modifications. However, these were easy to spot during visual interpretation, and the number of missed individual pitfall traps was still low. For the mapping of grave mounds, the automatic method produced a large number of false detections, reducing the usefulness of the semi-automatic approach. The mound structure is a very common natural terrain feature, and the grave mounds are less distinct in shape than the pitfall traps. Still, applying automatic mound detection on an entire municipality did lead to a new discovery of an Iron Age grave field with more than 15 individual mounds. Automatic mound detection also proved to be useful for a detailed re-mapping of Norway's largest Iron Age grave yard, which contains almost 1000 individual graves. Combined pit and mound detection has been applied to the mapping of more than 1000 charcoal kilns that were used by an iron work 350-200 years ago. The majority of charcoal kilns were indirectly detected as either pits on the circumference, a central mound, or both

    Even if specialists in fields related to the underwater cultural heritage sometimes express their differences, or even think that their opposite positions are insurmountable, it is obvious that we all share the same concern regarding the preservation of this legacy. It is time to overcome egotistical attitudes that speak about ownership and dominium, and instead talk about co-responsibility. The 2001 UNESCO Convention is a helpful legal instrument and a two-way commitment that we, as professionals in the field, need to support. There is a difference between the empty promises of treasure hunters and the committed intentions and actions of researchers and managers. How can we respond to today's challenges? The key is cooperation.

    We present a technique for the multi-sensor registration of featureless datasets based on the photogrammetric tracking of the acquisition systems in use. This method is developed for the in situ study of cultural heritage objects and is tested by digitizing a small canvas successively with a 3D digitization system and a multispectral camera while simultaneously tracking the acquisition systems with four cameras and using a cubic target frame with a side length of 500 mm. The achieved tracking accuracy is better than 0.03 mm spatially and 0.150 mrad angularly. This allows us to seamlessly register the 3D acquisitions and to project the multispectral acquisitions on the 3D model. PMID:23322103

    A set of portable/transportable X-ray analytical instruments based on radiography, microtomography, fluorescence and diffraction have been built and are being operated at the Multidisciplinary Laboratory (MLAB) of the 'Abdus Salam' International Centre for Theoretical Physics (ICTP) in collaboration with Elettra-Sincrotrone Trieste. This is part of a project funded by the Region Friuli Venezia Giulia (Italy) and the ICTP, which aims to develop innovative X-ray analytical tools for noninvasive studies of cultural heritage objects and palaeontological remains. The X-ray instruments at MLAB are also used for hands-on training activities involving students and scientists from developing countries. The MLAB analytical tools complement the microtomography instruments available at Elettra-Sincrotrone Trieste. Examples of our first studies in archaeological and palaeontological applications are presented here.

    The easy generation of 3D geometries (point clouds or polygonal models) with fully automated image-based methods poses nontrivial problems on how to check a posteriori the quality of the achieved results. Clear statements and procedures on how to plan the camera network, execute the survey and use automatic tools to achieve the prefixed requirements are still an open issue. Although such issues had been discussed and solved some years ago, the importance of camera network geometry is today often underestimated or neglected in the cultural heritage field. In this paper different camera network geometries, with normal and convergent images, are analyzed and the accuracy of the produced results are compared to ground truth measurements.

    A new acquisition system for remote control of wall paintings has been realized and tested in the field. The system measures temperature and atmospheric pressure in an archeological site where a fresco has been put under control. The measuring chain has been designed to be used in unfavorable environments where neither electric power nor telecommunication infrastructures are available. The environmental parameters obtained from the local monitoring are then transferred remotely allowing an easier management by experts in the field of conservation of cultural heritage. The local acquisition system uses an electronic card based on microcontrollers and sends the data to a central unit realized with a Raspberry-Pi. The latter manages a high quality camera to pick up pictures of the fresco. Finally, to realize the remote control at a site not reached by internet signals, a WiMAX connection based on different communication technologies such as WiMAX, Ethernet, GPRS and Satellite, has been set up.

    All societies attempt to preserve their cultural heritage because it is this that gives them their identity. How artefacts are identified as being of significance to society, and how to preserve these for posterity, depend on the sophistication of those societies, their wealth, and the determination of members of the societies to preserve their past. If conservation or restoration measures are being undertaken complex analytical experiments must be undertaken beforehand to ensure that the work is being undertaken in an appropriate manner. These investigations may employ electromagnetic (IR, VIS, UV, X-ray, γ-ray) or particulate (electron, proton, neutron, and ion beams) radiation. The use of many of these techniques is described in this paper in experiments on Australian Aboriginal bark paintings, a suit of armour belonging to a famous Australian outlaw, and the degradation of colour motion picture film.

    Currently, there is a rapid development in the techniques of the automated image based modelling (IBM), especially in advanced structure-from-motion (SFM) and dense image matching methods, and camera technology. One possibility is to use video imaging to create 3D reality based models of cultural heritage architectures and monuments. Practically, video imaging is much easier to apply when compared to still image shooting in IBM techniques because the latter needs a thorough planning and proficiency. However, one is faced with mainly three problems when video image sequences are used for highly detailed modelling and dimensional survey of cultural heritage objects. These problems are: the low resolution of video images, the need to process a large number of short baseline video images and blur effects due to camera shake on a significant number of images. In this research, the feasibility of using video images for efficient 3D modelling is investigated. A method is developed to find the minimal significant number of video images in terms of object coverage and blur effect. This reduction in video images is convenient to decrease the processing time and to create a reliable textured 3D model compared with models produced by still imaging. Two experiments for modelling a building and a monument are tested using a video image resolution of 1920×1080 pixels. Internal and external validations of the produced models are applied to find out the final predicted accuracy and the model level of details. Related to the object complexity and video imaging resolution, the tests show an achievable average accuracy between 1 - 5 cm when using video imaging, which is suitable for visualization, virtual museums and low detailed documentation.

    As a rule, image-based documentation of cultural heritage relies today on ordinary digital cameras and commercial software. As such projects often involve researchers not familiar with photogrammetry, the question of camera calibration is important. Freely available open-source user-friendly software for automatic camera calibration, often based on simple 2D chess-board patterns, are an answer to the demand for simplicity and automation. However, such tools cannot respond to all requirements met in cultural heritage conservation regarding possible imaging distances and focal lengths. Here we investigate the practical possibility of camera calibration from unknown planar objects, i.e. any planar surface with adequate texture; we have focused on the example of urban walls covered with graffiti. Images are connected pair-wise with inter-image homographies, which are estimated automatically through a RANSAC-based approach after extracting and matching interest points with the SIFT operator. All valid points are identified on all images on which they appear. Provided that the image set includes a "fronto-parallel" view, inter-image homographies with this image are regarded as emulations of image-to-world homographies and allow computing initial estimates for the interior and exterior orientation elements. Following this initialization step, the estimates are introduced into a final self-calibrating bundle adjustment. Measures are taken to discard unsuitable images and verify object planarity. Results from practical experimentation indicate that this method may produce satisfactory results. The authors intend to incorporate the described approach into their freely available user-friendly software tool, which relies on chess-boards, to assist non-experts in their projects with image-based approaches.

    Scientists are using high-energy X-ray instruments to solve mysteries behind art masterpieces, including artwork by Picasso. Learn how Argonne National Laboratory is working with major art institutions, such as The Art Institute of Chicago and Smithsonian Institute, to unlock groundbreaking information about art, the artist, and our cultural heritage. A deep connection to our past and shared cultural heritage must be preserved to foster a balanced society where all humanity can thrive. This talk will describe analysis of paint materials used by Pablo Picasso at the nanoscale, as only possible at the brightest synchrotron sources. It will highlight how new imaging techniques can reveal the invisible, bringing to light underlying compositions of old masters' paintings. This in turn enables the writing of new art history and provides important material clues that can assist with attribution and authentication. We will explain how the use of new technology can lead to new discoveries, which, in turn, can change the public's and the specialists' perception of great works of art. In collaboration with scientists from The Art Institute of Chicago we have teamed up to study the chemical make up of zinc oxide pigments used in artworks by Pablo Picasso. We will show how highly focused X-ray beams with nanoscale spatial resolution and trace element sensitivity have helped to determine that Picasso has used conventional house paint in some of his paintings. Surprisingly, the study gives also new insights into the pigment material zinc oxide, which has also great potential in a variety of applications such as in spintronics or as transparent electrodes in solar panels.

He explained that CHARISMA was for people working in Europe (or in associated countries). There was some discussion then about the need for a similar sort of network being established for the Middle East region. The proceedings contain peer reviewed papers presented at the conference. During the conference and in collaboration with the Sharjah Department of Culture and Information (Directorate of Antiquities), the American University of Sharjah organized an archaeology exhibition from the 30 November until the 10 December 2011. Special thanks go to Dr Sabah Jasim and Eisa Abbas from the Sharjah Directorate of Antiquities for facilitating this event. The exhibition included about 45 artifacts from different sites within Sharjah emirate, some of which dated as far back 7000 years ago. These artifacts included: flint arrowheads, pottery and alabaster vessels, metal objects including bronze arrowheads and coins, as well as carnelian bead necklaces. Also coinciding with the XTACH11 conference, the American University of Sharjah, in cooperation with The International Atomic Energy Agency (IAEA) and the National X-ray Fluorescence Laboratory organized a regional training course from 3-8 December 2011. This covered a similar range of topics to those discussed at the XTACH11 conference. Participants of the course were trained in the use of physical and analytical techniques in cultural heritage. In addition to lectures from the National X-ray Fluorescence Laboratory and from the IAEA, the NXFL team provided the opportunity for trainees to undertake projects on ancient pottery samples, metal artifacts and Islamic manuscripts. The practical part of the course included experiments on XRF (portable, and micro XRF

Statistics calculated relatively objective mural surface area from volume data, providing more accurate quantitative data for the mural conservation, especially, providing a viable technology for accurate monitoring of continued degradation. We believe, in order to make use of the three-dimensional laser scanning technology in a digital heritage conservation application, the technology should not only be used to record the object geometry and play a role in record keeping aspects, but, rather, should be used during the investigation to protect against targeted degradation and a more meaningful interpretation function. Like the development of the medical application of X-ray technology not only retains a picture, but more importantly, through this technical interpretation of patient pathology, guides doctors in carrying out the treatment work. Therefore, in the process of digitization of cultural heritage research, the focus should shift to the use of digital technology in the analysis of heritage object degradation and degradation monitoring surveys can promote the application of digital technology in the conservation of cultural heritage.

    In the last decades the need for an effective seismic protection and vulnerability reduction of cultural heritage buildings and sites determined a growing interest in structural health monitoring (SHM) as a knowledge-based assessment tool to quantify and reduce uncertainties regarding their structural performance. Monitoring can be successfully implemented in some cases as an alternative to interventions or to control the medium- and long-term effectiveness of already applied strengthening solutions. The research group at the University of Padua, in collaboration with public administrations, has recently installed several SHM systems on heritage structures. The paper reports the application of monitoring strategies implemented to avoid (or at least minimize) the execution of strengthening interventions/repairs and control the response as long as a clear worsening or damaging process is detected. Two emblematic case studies are presented and discussed: the Roman Amphitheatre (Arena) of Verona and the Conegliano Cathedral. Both are excellent examples of on-going monitoring activities, performed through static and dynamic approaches in combination with automated procedures to extract meaningful structural features from collected data. In parallel to the application of innovative monitoring techniques, statistical models and data processing algorithms have been developed and applied in order to reduce uncertainties and exploit monitoring results for an effective assessment and protection of historical constructions. Processing software for SHM was implemented to perform the continuous real time treatment of static data and the identification of modal parameters based on the structural response to ambient vibrations. Statistical models were also developed to filter out the environmental effects and thermal cycles from the extracted features.

    Around the present and old coastal areas of the Mediterranean Sea, the outcropping of soft calcareous and arenaceous stones (calcareous tuffs, encroutement calcaires, etc.) favoured the establishment and development of rupestrian civilizations. In many areas, these settlements raise a particular significance under anthropological and artistic point of view, such as the Matera "Sassi", an Italian UNESCO World Heritage site. A number of cultural heritages remnants, consisting of rupestrian establishments which have artistic and cultural significance, are diffused on the Gravine and on the Lame (local name of major and minor canyons) of the Murgia flanks (Southern Italy). It is required to preserve these cultural assets, even having such an objective, a new use of them with exhibition purposes. The most common environment on which are found these settlements are the slopes of the Gravine, carved into calcarenites. Despite to its excellent characteristic (good resistance coupled with an excellent workability), calcarenite is subject to decay for the negative interaction with the water of capillary or hygroscopic absorption. The absorbed water by the rock interacts with each of its three phases, clastic or bioclastic granules of calcium carbonate, matrix and cement, but in particular with the carbonate cement which determine, in function of its concentration, dissolution or precipitation processes with synchronous effects on the technical properties of the rock. Therefore the structural weakening of the calcarenite leads to the possibility of brittle fracture of statically relevant parts of naturally or artificially carved mass, often in contexts where the actual geometry and the perception of risk cannot be properly evaluated. The fragility of the contexts, where the excavated continues with parts constructed with the same materials, leads to disastrous evolutions of the same in case of failure. Recent studies on the underground cavities have allowed an assessment of

    In the framework of the bilateral scientific cooperation programme between Italy and China a project financed by Italian of Ministry Affairs on Earth Observation and ICT for cultural heritage has been starting since 2013 with the participation of researchers of two Italian institutes of CNR, IBAM and IMAA, and of Centre for Earth Observation and Digital Earth of Chinese Academy of Sciences. The aims of this project is to achieve advances in knowledge, methods and technologies to support a smart management of cultural sites which require constant monitoring activities to preserve their integrity by means of synergic Italian-Chinese research activities, training and exchanges of working experience in the field of remote sensing, geophysics, virtual reality and geomatics applied to Cultural Heritage. During the three years of the project, a number of case studies in China and in Italy will represent the test areas to implement in a synergic way different remote sensing approaches from space-borne to airborne remote sensing (Lasaponara and Masini 2011, 2013; Masini and Lasaponara 2013), including UAV, up to geophysics and terrestrial survey methods with different aims, from site discovery to monitoring and management of cultural sites. The paper shows the preliminary results of three case studies in China. One is Luoyang in the western Henan province, located at the intersection of the Luo and Yi rivers, an area that was once considered the center of China. For this reason its territory more times hosted the capital during different dynasties. The first was built on 2070 BCE, during the Xia Dynasty. Another capital of Eastern Han Dynasty was found in 25 AD by Emperor Guangwu of Han. During the Eastern Han Dynasty Luoyang was the most important town of China, from the political, religious and cultural point of view. A few architectural monuments of this period are preserved, among them the White Horse Temple, built on preexisting structures of the first Buddhist temple

    This paper discusses the limitation of existing data structures in mobile mapping applications to support archaeologists to manage the artefact (any object made or modified by a human culture, and later recovered by an archaeological endeavor) details excavated at a cultural heritage site. Current limitations of data structure in the mobile mapping application allow archeologist to record only one artefact per test pit location. In reality, more than one artefact can be excavated from the same test pit location. A spatial data model called Artefact Mobile Data Model (AMDM) was developed applying existing Relational Data Base Management System (RDBMS) technique to overcome the limitation. The data model was implemented in a mobile database environment called SprintDB Pro which was in turn connected to ArcPad 7.1 mobile mapping application through Open Data Base Connectivity (ODBC). In addition, the design of a user friendly application built on top of AMDM to interpret and record the technology associated with each artefact excavated in the field is also discussed in the paper. In summary, the paper discusses the design and implementation of a data model to facilitate the collection of artefacts in the field using integrated mobile mapping and database approach.

    The paper describes reading criteria for the documentation for important buildings in Milan, Italy, as a case study of the research on the integration of new technologies to obtain 3D multi-scale representation architectures. In addition, affords an overview of the actual optical 3D measurements sensors and techniques used for surveying, mapping, digital documentation and 3D modeling applications in the Cultural Heritage field. Today new opportunities for an integrated management of data are given by multiresolution models, that can be employed for different scale of representation. The goal of multi-scale representations is to provide several representations where each representation is adapted to a different information density with several degrees of detail. The Digital Representation Platform, along with the 3D City Model, are meant to be particularly useful to heritage managers who are developing recording, documentation, and information management strategies appropriate to territories, sites and monuments. Digital Representation Platform and 3D City Model are central activities in a the decision-making process for heritage conservation management and several urban related problems. This research investigates the integration of the different level-of-detail of a 3D City Model into one consistent 4D data model with the creation of level-of-detail using algorithms from a GIS perspective. In particular, such project is based on open source smart systems, and conceptualizes a personalized and contextualized exploration of the Cultural Heritage through an experiential analysis of the territory.

Recently, the interest on THz technology is also growing up thanks to the development of flexible and compact commercial systems having source and detector probes coupled by means of optical fiber cables and that do not require complex optical alignments. These features allow us to reconfigure the measurement configuration easily; thus transmission, normal reflection and oblique reflection data can be collected according to the constrains and objective of the survey to be performed. Moreover, they open the way to on field applications. An example of last generation THz systems is the Fiber-Coupled Terahertz Time Domain System (FICO) marketed by Z-Omega and available at the Institute of Electromagnetic Sensing of the Environment. Such a system is designed to perform both transmission and reflection spectroscopy and imaging measurements in the range from 60GHz to 3THz; with a waveform acquisition speed up to 500Hz. A review of the literature assessing potentialities and open challenges of THz spectroscopy and imaging in the frame of cultural heritage preservation will be provided at the conferences, with a specific focus on the diagnostic capabilities of last generation systems.

  6. Challenges and Strategies for Quantitive Ground Penetrating Radar Diagnostics of Cultural Heritage

    High resolution non-invasive surveys based on Ground Penetrating Radar are exploited in many different applications, including cultural heritage diagnostics. In this framework, the interaction of the probing wave with an inaccessible region is useful for instance to provide information on the inner status of a structure, so to call for maintenance, or to characterize an underground scenario, so to address the following excavations. While the large part of GPR surveys is still based on 'traditional' radar-like techniques, which require a significant interpretation stage by an expert user, microwave tomography (MT) strategies based on inverse scattering have been recently gaining an increasing attention. As a matter of fact, these techniques are capable of achieving images which are stable with respect to measurement noise and uncertainties on the scenario, therefore being minimally dependent on the end-user's interpretation. So far, MT strategies adopted in GPR surveys are based on an approximated formulation which neglects the underlying non-linearity of the inverse problem. Such a circumstance, that greatly simplifies their practical application, limits the achievable performances, as it prevents one from achieving a quantitative assessment of the scenario under test in terms of location, shape and electormagnetic parameters of the embedded 'anomalies'. Obviously, the potential advantage resulting from such a completely objective assessment is apparent, since an imaging method able to deliver quantitative information entails a dramatic reduction of costs and a definite improvement in the effectiveness of maintenance operations. Therefore, a stimulating challenge is to proceed towards the development of imaging strategies that rely on full-wave models and which are thus capable of providing these added-value results. However, such an aim is not a trivial one pursue, since one has to tackle the inverse problem in its fully non-linearity and ill-posedness. Indeed

    Central High-Atlas mountain in the centre of Morocco, contains an exceptional geodiversity. Some geomorphological and geological objects of it are included and protected recently by the World Heritage list. The valley of Aït Bou Oulli is located in the heart of the Moroccan central High-Atlas, whose height is 4068 m in Ighil M'goun and 3800 m in Rat Mountain. The mountain areas are characterized by higher geodiversity in comparison with other areas. The valley possesses a geological and geomorphological heritage which is very rich, much diversified and exceptional landscapes of high mountains. It is part of geopark M'Goun; the valley attracts a number of tourists every year. However, this number remains restricted because of the lack of the tools of promotion, valuation and mediation of this geoheritage. Moreover, the touristic infrastructure is modest. Regarding this situation, the geotouristic map appears as a tool of promotion of the geotourism and diversification of the regional and national tourist product. This work aims at elaborating new maps of geomorphosites, cultural sites, and geomonuments in high Mountain landscapes of the valley, suggested in geotourism circuits. The first results reveal the low exploitation of the geodiversity of this valley-oasis: the spectacular waterfalls, water sources, canyons, glacial cirques and U-shaped valleys, superficial karstic forms (sinkholes and swallow-holes), high-Atlas peaks and cliffs, spectacular scree slopes, badlands landscapes, fairy chimneys, and the geological history dating back to the Paleozoic and angular unconformity. In addition, the valley has diverse tangible cultural heritage spanning hundreds of years such as the enigmatic rock engravings (dating from 2000 to 3000 years), troglodyte caves and terraced agriculture landscapes, geomonuments (old cooperative storage, Kasbah, traditional water mills) and the architecture of the villages. It has also an intangible cultural heritage such as folklore. This

    In this paper, we examine the possibility to use on-site permeability measurements for cultural heritage applications as an alternative for traditional laboratory tests such as determination of the capillary absorption coefficient. These on-site measurements, performed with a portable air permeameter, were correlated with the pore network properties of eight sandstones and one granular limestone that are discussed in this paper. The network properties of the 9 materials tested in this study were obtained from micro-computed tomography (μCT) and compared to measurements and calculations of permeability and the capillary absorption rate of the stones under investigation, in order to find the correlation between pore network characteristics and fluid management characteristics of these sandstones. Results show a good correlation between capillary absorption, permeability and network properties, opening the possibility of using on-site permeability measurements as a standard method in cultural heritage applications.

    We present an overview of recent advances in the application of Fourier Transform Infrared (FTIR) microscopy for analysis of complex, multicomponent, and multilayer samples such as those typically encountered in the field of heritage materials. This technique is particularly useful since it allows identification and localization of both organic and inorganic (if IR active) compounds. New improvements have been possible thanks to the introduction of ad hoc sample preparation methods to obtain either thin or cross sections that allow both avoidance of contamination from organic embedding resin and improvement of the quality of the acquired spectra. Moreover, integrated use of spectra registered in the near-infrared (NIR) and mid-infrared (MIR) regions allows better comprehension of cross section composition. Data interpretation has been improved thanks to the development of chemometric methods for elaboration of hyperspectral data. A new and very promising field is the development of enhanced FTIR methods for detection of trace components in microextracts. These systems, allowing detection of extractable organic compounds from about 0.1 mg of sample, will be extremely useful in the future for analysis of natural and synthetic colorants, varnishes extracted, for instance, from cotton swabs used during cleaning of paintings, and organic residues on archeological remains.

    This paper introduces the aims and early activities of Colour and Space in Cultural Heritage (COSCH), an interdisciplinary European network of experts in the latest optical measuring techniques and electronic imaging applied to documentation of artefacts. COSCH is a forum open to organisations, institutions and companies interested in collaboration within the emerging field of precise spectral and spatial imaging techniques, in physical and chemical sciences applied to cultural heritage objects, as well as in research and applications to conservation and art-historical analysis of such objects. COSCH started in November 2012. Funded by COST, an intergovernmental framework for European Cooperation in Science and Technology, COSCH networking activities enable knowledge exchange and coordination of nationally-funded research on a European level with occasional contribution of experts from other countries. Funding has been made available for four years (2012-2016). Participation is open to researchers across a wide range of disciplines, including computer scientists and museum professionals, art historians and academics in heritage-related fields. COSCH is a trans-domain Action (TD1201) of the COST Domain Materials, Physics and Nanosciences (MPNS) which facilitates and promotes innovation in material science. The work of COSCH is defined in the Memorandum of Understanding between the COST Office and the Chairman of COSCH. The Memorandum is available from http://www.cost.eu/domains_actions/mpns/Actions/TD1201 alongside the latest progress report and other documents. The scientific work draws on earlier and current research of the participants and is organised around the following areas: spectral and spatial object documentation; algorithms and procedures; analysis and restoration of surfaces and objects of material culture; visualisation of cultural heritage objects and its dissemination

    In the context of cultural heritage, an accurate and comprehensive digital survey of a historical building is today essential in order to measure its geometry in detail for documentation or restoration purposes, for supporting special studies regarding materials and constructive characteristics, and finally for structural analysis. Some proven geomatic techniques, such as photogrammetry and terrestrial laser scanning, are increasingly used to survey buildings with different complexity and dimensions; one typical product is in form of point clouds. We developed a semi-automatic procedure to convert point clouds, acquired from laserscan or digital photogrammetry, to a filled volume model of the whole structure. The filled volume model, in a voxel format, can be useful for further analysis and also for the generation of a Finite Element Model (FEM) of the surveyed building. In this paper a new approach is presented with the aim to decrease operator intervention in the workflow and obtain a better description of the structure. In order to achieve this result a voxel model with variable resolution is produced. Different parameters are compared and different steps of the procedure are tested and validated in the case study of the North tower of the San Felice sul Panaro Fortress, a monumental historical building located in San Felice sul Panaro (Modena, Italy) that was hit by an earthquake in 2012.

    STUDY OBJECTIVE—This study investigates the spatial pattern of tumours in Europe to check the feasibility of a large scale ecological epidemiology approach to cancer in Europe.
SETTING—The tumour types relative frequencies and cancer incidence (for men and women) reported in the European cancer registries were investigated by exploratory data analysis techniques. Socioeconomical descriptors of the female condition were considered as well.
MAIN RESULTS—The classification of the European regional areas covered by the cancer registries followed almost exactly the boundaries set by the long and intermingled European history in terms of life styles and cultural heritage. This result supports the notion of a predominant role of environmental factors in cancer induction. Further support to the above result was given by the finding of a correlation between differential male-female cancer incidence, and socioeconomic descriptors of the female condition.
CONCLUSIONS—From a methodological point of view, the consistency of these results pointed to the feasibility of an ecological approach to tumour epidemiology.

    Dielectric constant measurement has been used in rocks characterization, mainly for exploration objective in geophysics, particularly related to ground penetration radar characterization in ranges of 10 MHz to 1 GHz. However, few data have been collected for loss factor. Complex permittivity (dielectric constant and loss factor) characterization in rock provide information about mineralogical composition as well as other petrophysic parameters related to the quality, such as fabric parameters, mineralogical distribution, humidity. A study was performed in the frequency of 2,45GHz by using a portable kit for dielectric device based on an open coaxial probe. In situ measurements were made of natural stone marble and granite on selected industrial slabs and building stone. A mapping of their complex permittivity was performed and evaluated, and variations in composition and textures were identified, showing the variability with the mineral composition, metal ore minerals content and fabric. Dielectric constant was a parameter more sensible to rock forming minerals composition, particularly in granites for QAPF-composition (quartz-alkali feldspar-plagioclases-feldspathoids) and in marbles for calcite-dolomite-silicates. Loss factor shown a high sensibility to fabric and minerals of alteration. Results showed that the dielectric properties can be used as a powerful tool for petrographic characterization of building stones in two areas of application: a) in cultural heritage diagnosis to estimate the quality and alteration of the stone, an b) in industrial application for quality control and industrial microwave processing.

  15. Parametric Accuracy: Building Information Modeling Process Applied to the Cultural Heritage Preservation

    Since their introduction, modeling tools aimed to architectural design evolved in today's "digital multi-purpose drawing boards" based on enhanced parametric elements able to originate whole buildings within virtual environments. Semantic splitting and elements topology are features that allow objects to be "intelligent" (i.e. self-aware of what kind of element they are and with whom they can interact), representing this way basics of Building Information Modeling (BIM), a coordinated, consistent and always up to date workflow improved in order to reach higher quality, reliability and cost reductions all over the design process. Even if BIM was originally intended for new architectures, its attitude to store semantic inter-related information can be successfully applied to existing buildings as well, especially if they deserve particular care such as Cultural Heritage sites. BIM engines can easily manage simple parametric geometries, collapsing them to standard primitives connected through hierarchical relationships: however, when components are generated by existing morphologies, for example acquiring point clouds by digital photogrammetry or laser scanning equipment, complex abstractions have to be introduced while remodeling elements by hand, since automatic feature extraction in available software is still not effective. In order to introduce a methodology destined to process point cloud data in a BIM environment with high accuracy, this paper describes some experiences on monumental sites documentation, generated through a plug-in written for Autodesk Revit and codenamed GreenSpider after its capability to layout points in space as if they were nodes of an ideal cobweb.

  16. The Application of Gpr To The Estimation of Rock Fall Hazard To Cultural Heritage

    NASA Astrophysics Data System (ADS)

    Roch, K.-H.; Chwatal, W.; Brückl, E.

    The old town of Salzburg (Austria) belongs to the world cultural heritage. Several historic buildings are situated at the toe of steep rock walls and are threatened by con- siderable hazard of rock fall. The rock wall of the "Mönchsberg" (consisting of con- glomerate) in the old town of Salzburg was investigated by GPR (ground penetrating radar) along 39 profiles, covering an area of 3500m2, in order to detect discontinuities relevant for the development of rock falls. The topography of the rock wall was accu- rately mapped by photogrammetric methods. In fact a coherent discontinuity with an extent of about 350m2 was found. This discontinuity was correlated with a bulge of the rock wall. The results of repeated measurements in this area after one and a half year were of essential significance. It could be shown that no substantial variation in the extent of the discontinuity occurred. Some variation was detected in the dielec- tric contrast, probably due to seasonal variation of moisture. Altogether the results demonstrate GPR is an appropriate method for supervising rock walls, especially in urban environments.

    Today, the need for preservation of cultural heritage as an important, irreplaceable resource for human is well recognized. In this regard, prior to any conservational measure, detailed documentation and recording of these precious resources should be performed; since this way, not only preservation requirements of the object will be identified, but also the existing condition will be recorded for future generations. Accordingly, since Iran is known as an ancient land possesses valuable historic resources, and due the numerousness of Iran's monuments and the high possibility of occurring natural disasters which are counted as significant threats for the monuments, the necessity of fast and appropriate documentation in this country will be clarified. This paper is in fact a part of the project entitled "Study of the application of digital technologies in recording and rehabilitation of historic buildings" in Iran. Here, the surveying process of aforesaid project's case study which is one of the two Kharraqan Tomb Towers placed in Qazvin province of Iran, using close range photogrammetry and low cost equipment will be demonstrated.

  18. Combined Neutron and X-ray Imaging for Non-invasive Investigations of Cultural Heritage Objects

    Mannes, D.; Schmid, F.; Frey, J.; Schmidt-Ott, K.; Lehmann, E.

    The combined utilization of neutron and X-ray imaging for non-invasive investigations of cultural heritage objects is demonstrated on the example of a short sword found a few years ago in lake Zug, Switzerland. After conservation treatments carried out at the Swiss National Museum the sword was examined at the Paul Scherrer Institut (PSI), Villigen (CH), by means of neutron and X-ray computer tomography (CT). The two types of radiation show different interaction behavior with matter, which makes the two methods complementary. While X-rays show a strong correlation of the attenuation with the atomic number, neutrons demonstrate a high sensitivity for some light elements, such as Hydrogen and thus organic material, while some heavy elements (such as Lead) show high penetrability. The examined object is a composite of metal and organic material, which makes it an ideal example to show the complementarity of the two methods as it features materials, which are rather transparent for one type of radiation, while yielding at the same time high contrast for the other. Only the combination of the two methods made an exhaustive examination of the object possible and allowed to rebuild an accurate replica of the sword.

    In this paper, we propose a new sensor for the detection and analysis of dusts (seen as powders and fibers) in indoor environments, especially designed for applications in the field of Cultural Heritage or in other contexts where the presence of dust requires special care (surgery, clean rooms, etc.). The presented system relies on image processing techniques (enhancement, noise reduction, segmentation, metrics analysis) and it allows obtaining both qualitative and quantitative information on the accumulation of dust. This information aims to identify the geometric and topological features of the elements of the deposit. The curators can use this information in order to design suitable prevention and maintenance actions for objects and environments. The sensor consists of simple and relatively cheap tools, based on a high-resolution image acquisition system, a preprocessing software to improve the captured image and an analysis algorithm for the feature extraction and the classification of the elements of the dust deposit. We carried out some tests in order to validate the system operation. These tests were performed within the Sistine Chapel in the Vatican Museums, showing the good performance of the proposed sensor in terms of execution time and classification accuracy. PMID:24901977

    The combined use of high-resolution digital images taken from ground as well as from RPAS (Remotely Piloted Aircraft Systems) have significantly increased the potential of close range digital photogrammetry applications in Cultural Heritage surveying and modeling. It is in fact possible, thanks to SfM (Structure from Motion), to simultaneously process great numbers of aerial and terrestrial images for the production of a dense point cloud of an object. In order to analyze the accuracy of results, we started numerous tests based on the comparison between 3D digital models of a monumental complex realized by the integration of aerial and terrestrial photogrammetry and an accurate TLS (Terrestrial Laser Scanner) reference model of the same object. A lot of digital images of a renaissance castle, assumed as test site, have been taken both by ground level and by RPAS at different distances and flight altitudes and with different flight patterns. As first step of the experimentation, the images were previously processed with Agisoft PhotoScan, one of the most popular photogrammetric software. The comparison between the photogrammetric DSM of the monument and a TLS reference one was carried out by evaluating the average deviation between the points belonging to the two entities, both globally and locally, on individual façades and architectural elements (sections and particular). In this paper the results of the first test are presented. A good agreement between photogrammetric and TLS digital models of the castle is pointed out.

    Speaking about modelling the Cultural Heritage, nowadays it is no longer enough to build the mute model of a monument, but it has to contain plenty of information inside it, especially when we refer to existing construction. For this reason, the aim of the research is to insert an historical building inside a BIM process, proposing in this way a working method that can build a reality based model and preserve the unicity of the elements. The question is: "What is the more useful mean in term of survey data management, level of detail, information and time savings?" To test the potentialities and the limits of this process we employed the most used software in the international market, taking as example some composed elements, made by regular and complex, but also modular parts. Once a final model is obtained, it is necessary to provide a test phase on the interoperability between the used software modules, in order to give a general picture of the state of art and to contribute to further studies on this subject.

    In this paper we present the results of the development of a Web-based archiving and documenting system aimed to the management of multisource and multitemporal data related to cultural heritage. As case study we selected the building complex of Villa Revedin Bolasco in Castefranco Veneto (Treviso, Italy) and its park. Buildings and park were built in XIX century after several restorations of the original XIV century area. The data management system relies on a geodatabase framework, in which different kinds of datasets were stored. More specifically, the geodatabase elements consist of historical information, documents, descriptions of artistic characteristics of the building and the park, in the form of text and images. In addition, we used also floorplans, sections and views of the outer facades of the building extracted by a TLS-based 3D model of the whole Villa. In order to manage and explore these rich dataset, we developed a geodatabase using PostgreSQL and PostGIS as spatial plugin. The Web-GIS platform, based on HTML5 and PHP programming languages, implements the NASA Web World Wind virtual globe, a 3D virtual globe we used to enable the navigation and interactive exploration of the park. Furthermore, through a specific timeline function, the user can explore the historical evolution of the building complex.

    In recent years many earthquakes hit Italy and its Cultural Heritage. The topic of survey of buildings damaged by seismic events and their interpretation has become very relevant and involved many research groups and Italian Civil Protection. The damage survey has different roles: in the first stage, immediately after the emergency, the documentation is necessary for the shoring and protection of damaged structures (AEDES forms of Civil Protection). The aim of the second stage is the study and the documentation for the restoration, reconstruction and retrofitting of buildings. In this context, this study presents methods and instruments used in the survey of 24 churches in the province of Mantua, Lombardy, after the 2012 earthquake sequence. The paper examines the difficulties in surveying damaged buildings and presents the classification used to define, time by time, the most suitable survey approach in the field of Geomatics. In this classification, many aspects are taken into account, such as logistical and practical problems, safety conditions, time preserving methods, economic decisions, complexity of building and required results. The accurate documentation obtained as a three-dimensional architectural database allows for the observation and analysis of the damage, the definition of interpretative models and the development of intervention projects. Different results are obtained from the point cloud database: traditional 2D representations for architectural projects as well as 3D models for structural analysis or for the development of BIM.

  4. Landslide Monitoring and Cultural Heritage At Risk: The Case Study of San Miniato Hill In Florence

    NASA Astrophysics Data System (ADS)

    Agostini, G.; Casagli, N.; Delmonaco, G.; Fanti, R.; Focardi, P.; Margottini, C.

    San Miniato (known also as Monte alle Croci or Mons Florentinus) is the most fa- mous hill bordering the southern side of the historic center of Florence. Included in the SColli FiorentiniT (Florentine hills) overlooking the monuments and artworks of Flo- & cedil;rence, San Miniato provides a wonderful view of the city. The hillside has always been affected by slope instability phenomena, with periodical reactivations documented in several historic records. Most of the monuments and artworks located on the hill are cracked and fissured and have required restoration works in various circumstances in the centuries after their construction. The first documented studies on the stability of the hill were carried out by Leonardo da Vinci in the XV century and subsequently by various commissions appointed for the restoration works. During the XX century the hill was many times monitored with geotechnical instrumentation and some investiga- tions are still in progress today. This work concerns a review of these historical studies on slope instability and the interpretation of past and present monitoring results. An analytical review of the existing data is a necessary condition for the proposal of a reliable hypothesis concerning the slope instability characterization. This is made dif- ficult by the pluri-centenary urbanization of the entire hill which has led to the almost complete obliteration of the evidence of past movements and by the relevant presence of an invaluable artistic and cultural heritage.

    2014-06-01

    In the field of Cultural Heritage, the use of automated photogrammetric systems, based on Structure from Motion techniques (SfM), is widely used, in particular for the study and for the documentation of the ancient ruins. This work has been carried out during the PhD cycle that was produced the "Carta Archeologica del territorio intorno al monte Massico". The study suggests the archeological documentation of the mausoleum "Torre del Ballerino" placed in the south-west area of Falciano del Massico, along the Via Appia. The graphic documentation has been achieved by using photogrammetric system (Image Based Modeling) and by the classical survey with total station, Nikon Nivo C. The data acquisition was carried out through digital camera Canon EOS 5D Mark II with Canon EF 17-40 mm f/4L USM @ 20 mm with images snapped in RAW and corrected in Adobe Lightroom. During the data processing, the camera calibration and orientation was carried out by the software Agisoft Photoscans and the final result has allowed to achieve a scaled 3D model of the monument, imported in software MeshLab for the different view. Three orthophotos in jpg format were extracted by the model, and then were imported in AutoCAD obtaining façade's surveys.

    Cultural tourism in the Pacific has always offered an underwater option for those who snorkel or are certified to dive. In addition to the coral reefs and marine life, World War II (WWII) shipwrecks, aircraft wrecks and other submerged vehicles draw hundreds of tourists to the Pacific each year. While it is encouraging that so many are interested in the cultural heritage of battlefields, these same visitors can cause considerable amounts of damage. This paper presents a case study of cultural impacts on submerged WWII sites in the Commonwealth of the Northern Mariana Islands (CNMI) where diving heritage tourism is a growing industry. Cultural impacts in the CNMI include a diverse range of direct and indirect impacts including vandalism, the act of memorialization, looting and collecting souvenirs, anchor and mooring damage, and moving artifacts. What is often viewed as detrimental cultural impacts by archaeologists and managers can also be examined as behavior that reflects various stakeholders' values and attitudes towards heritage sites. As such, these behaviors can and should be examined and considered concurrently during research and management discussions.

  8. Digital Documentation in the Conservation of Cultural Heritage: Finding the Practical in best Practice

    Documentation of treatment is one of the central tenets of conservation as a profession, and a necessary aspect of the preservation of cultural heritage. Photographic documentation has been an essential technique for recording the nature of heritage objects and illustrating conservation procedures. The routine use of digital photography in recent years has opened many avenues to conservators, but also poses unique threats to the long-term stability of the conservation record. Digital documentation is subject to decay just as physical or "analogue" records are, with the stark difference that digital data corrupts absolutely, where physical records can remain legible through various stages of deterioration. It is therefore necessary to understand the options that conservators have with regards to preservation of their records for the future. The various guidelines presently available regarding digital documentation may be synthesized into a coherent "best practice" specific to digital conservation documentation. This practice, however, must be reconsidered within the framework of what is necessary to ensure that photographic records are preserved, versus what is feasible. In order to determine if conservators are aware of the limitations of digital technology, thirty practicing conservators were asked to respond to a questionnaire regarding their own documentation practices. The responses identified a lack of best practice, and indicated that there are multiple factors which prevent conservators from developing effective methods for creating, storing, and accessing documentation. To address this, a modified form of best practice, the "best practical" method, is developed as a series of guidelines with the intent of being feasible for practicing conservators. This method aims to reduce the time and economic costs required of best practice, while minimizing the risk to the conservation record. The "best practical" guidelines are being designed to be applicable to a

    2015-08-01

    Since the Yuan Dynasty, the belief of Matsu had started to spread from the birthplace to the northern coastal areas in China. Matsu worship developed to the pinnacle with the official promotion on account of the government's dependence on grain transported by sea since the mid-Qing Dynasty. A large amount of Matsu temples emerged in coastal cities of Bohai Rim where it still keeps a large number of them until now. It has much relationship between the spread of Matsu culture and the flow of Fujian population. It was one of the main building way that the Matsu temples attached to the local hall of Fujian in Bohai Rim. The Hall of Fujian in Yantai, Which was built with materials taken from Fujian, in the feature of traditional architectural style from QuanZhou, is very different from the local building style of Yantai. This case indicates that maritime culture of the south area had spread and developed in the north areas under the promotion of the population flow and the economic transaction. The essay introduces briefly about the development of Matsu culture in Bohai Rim and takes the case study of the Hall of Fujian in Yantai analyzing its causes and features, and the value as Matsu heritage. Then the paper will discuss the conservation of Matsu culture mere include the tangible and the intangible culture heritage around the origin area, the heritages of the spread area also have the same importance significance. With the evolution of the society, it calls urgent attention and protection of Matsu culture in Bohai Rim.

    The Walloon Region in Belgium played a leading role in the world economy and in the industrial sciences and engineering since the 19th century. Several relicts, such as important industrial buildings or sites, are spread over a large area and are still dominating the current landscape. Some of these remnants are preserved as monuments, representing the industrial, cultural and ecological transition of the region during the last two centuries. Since 2012, UNESCO recognized the importance of four of the best preserved 19th and 20th century coal mining sites and classified them as World Heritage ("Major Mining Sites of Wallonia", Le Grand-Hornu, Bois-du- Luc, Le Bois du Cazier and Blegny Mine). The four recognised mining sites together form a strip of about 170 km long, containing important examples of the so-called 'neo classical architecture' from the early periods of the industrial era in continental Europe. Motivated by this recognition and by the huge touristic and educational potential of the sites, a partnership between the Walloon government and Ghent University was organized. In this first stage, the collaboration focuses on the site of Bois-du-Luc in the municipality of La Louvière, containing a large series of dwellings, several equipments built between 1853 and 1923 by the Société des Charbonnages du Bois-du-Luc, workshops and heaps. Consisting of numerous buildings dating back to the period between 1838 and 1923, this site is one of Europe's oldest collieries. The collaboration between the Walloon government and Ghent University - Department of Geography fits in the hands-on training which students in land surveying and geomatics receive during their Bachelor studies. For the students it is very interesting that their practical exercises are not limited to the university campus, but that they are involved in a real measurement campaign. The project consists of a series of intensive land surveying campaigns, resulting in highly detailed and accurate

    There are many master pieces of the cultural heritage which cańt be correctly contemplated if daylight is not part of the exhibition environment, since they were made with the sun light as essential element of them. The Pórtico de la Gloria and the Cloister and paintings of Santa María de El Paular monastery are ones of these cases. The Pórtico de la Gloria (Gate of the Glory) is probably the most relevant masterpiece of the Santiago de Compostela cathedral. It is located at the narthex of the west gate. It is a masterwork of Romanesque sculpture built between 1168 and 1188 by Master Mateo. During the XVIII century a new Baroque façade was placed in front of it replacing the middle ages wall. Daylight entering through the windows of the facade makes possible to see the art work but the sun can generate serious problems since it heats the stone and evaporates the humidity. Thermal imagers have been used to test the thermal performance of the antireflection treatment located in the windows in the actual temperature of the stone sculptures. The cloister of the monastery of Santa María de El Paular, housed until the confiscation of 1835 a collection of 54 paintings of Vincente Carducho called Carthusian series. When in 2006 the restoration of the 52 still preserved paintings was completed, began a refurbishment of the cloister to return the paintings to their original place. We conducted a study of the incidence of the Sun in the cloister and how to avoid direct sunlight on Carducho's paintings.

    In this paper, a Cultural Heritage survey, performed by employing and integrating different type of acquisition technologies (imagebased and active sensor based) is presented. The aim of the survey is to create a 3D multiscale database, therefore, different restitution scales, from the architectural-urban one to a detail one are taken in consideration. This research is part of a project financed by the Unesco for the study of historical gardens located in Mantua and Sabbioneta, and in particular for the Palazzo Te renaissance gardens in Mantua, which are reported in this paper. First of all, a general survey of the area has been realized by employing the classical aerial photogrammetry in order to provide the actual arboreal and urban furniture conditions of the gardens (1:500 scale). Next, a detailed photogrammetric survey of the Esedra courtyard in Palazzo Te has been performed by using a UAV system. At the end, laser scanning and traditional topography have been used for the terrestrial detailed acquisition of gardens and architectural façades (1:50-1:20 scale). The aim of this research is to create a suitable graphical documentation support for the study of the structure of the gardens, to analyze how they have been modified over the years and as an effective support for eventual future re-design. Moreover, the research has involved a certain number of botanic and archeological investigations, which have been duly acquired and modeled with image based systems. Starting from the acquired datasets with their acquisition scales, a series of comparative analysis have been performed, especially for those areas in which all the systems have been employed. The comparisons have been extracted by analyzing point cloud models obtained by using a topographical network. As a result, the multi-range approach efficiency, obtained by employing the actual available technologies have been illustrated in the present work.

    The acculturation gap-distress model purports that immigrant children acculturate faster than do their parents, resulting in an acculturation gap that leads to family and youth maladjustment. However, empirical support for the acculturation gap-distress model has been inconclusive. In the current study, 428 Mexican-American adolescents (50.2 % female) and their primary caregivers independently completed questionnaires assessing their levels of American and Mexican cultural orientation, family functioning, and youth adjustment. Contrary to the acculturation gap-distress model, acculturation gaps were not associated with poorer family or youth functioning. Rather, adolescents with higher levels of Mexican cultural orientations showed positive outcomes, regardless of their parents' orientations to either American or Mexican cultures. Findings suggest that youths' heritage cultural maintenance may be most important for their adjustment. PMID:26759225

    The Silk Road, a major traffic route across the Eurasia continent, has been a convergence for the exchange, communication and dissemination of various cultures such as nations, materials, religions and arts for more than two thousand years. And the cultural heritage along the long and complicate route has been also attractive. In recent years, the Silk Road - the Road Network along the Chang'an-Tianshan Mountain has been listed in the Directory of World Cultural Heritage. The rare and rich cultural resources along the Silk Road, especially those in the territory of China, have attracted attentions of the world. This article describes the research ideas, methods, processes and results of the planning design on the internet-based dissemination services platform system for cultural heritage resources. First of all, it has defined the targeting for dissemination services and the research methods applied for the Silk Road heritage resources, based on scientific and objective spatial measurement and research on history and geography, to carry on the excavation of values of cultural resource for the target users. Then, with the front-end art exhibit by means of innovative IT, time and space maps of cultural heritage resources, interactive graphics display, panoramic three-dimensional virtual tour, and the Silk Road topics as the main features, a comprehensive and multi-angle cultural resources dissemination services platform is built. The research core of the platform is a demand-oriented system design on the basis of cultural resources and features as the fundamental, the value of contemporary manifestation as the foundation, and cultural dissemination and service as a starting point. This platform has achieved, temporal context generalization, interest profiles extension, online and offline adaptation, and other prominent innovations. On the basis of routes heritage resource protection and dissemination services with complex relationship between time and space, and the

    further advantages such as: the absence of the false solutions (a question to be arisen in non linear inverse problems); the exploitation of well known regularization tools for achieving a stable solution of the problem; the possibility to analyze the reconstruction performances of the algorithm once the measurement configuration and the properties of the host medium are known. Here, we will present the main features and the reconstruction results of a linear inversion algorithm based on the Born approximation in realistic applications in archaeology and cultural heritage diagnostics. Born model is useful when penetrable objects are under investigations. As well known, the Born Approximation is used to solve the forward problem, that is the determination of the scattered field from a known object under the hypothesis of weak scatterer, i.e. an object whose dielectric permittivity is slightly different from the one of the host medium and whose extent is small in term of probing wavelength. Differently, for the inverse scattering problem, the above hypotheses can be relaxed at the cost to renounce to a "quantitative reconstruction" of the object. In fact, as already shown by results in realistic conditions [4, 5], the adoption of a Born model inversion scheme allows to detect, to localize and to determine the geometry of the object also in the case of not weak scattering objects.

    The Sassi of Matera are a unique example in the world of rock settlement, developed from natural caves carved into the rock and then molded into increasingly complex structures inside two large natural amphitheatres: the Sasso Caveoso and the Sasso Barisano. Thanks also to this aspects Matera is an UNESCO world heritage site and was elected European Capital of Culture in 2019. Our research focuses on the compatibility of the energy efficiency measures applied in of Sassi buildings with the recent MiBACT (Italian Ministry of Cultural Heritage) guidelines on "Energy efficiency improvements in the cultural heritage" and AiCARR (Italian Association of Air Conditioning) guidelines on "Energy efficiency of historical building". One of the essential measures highlighted by Mibact guidelines is ensure the Indoor Environmental Quality improvement of the historical architecture in order to preserve their identity and cultural heritage. These paper aims to analyze energy and environmental performance of different buildings typology and monuments present in the Sassi site. The energy performance and microclimate measures conducted on different type of building by non-destructive measurements and laboratory tests in situ are useful to verify and quantify the thermal characteristics of the envelopes of the Mediterranean tradition and also to demonstrate their capacity to ensure internal comfort conditions. The calcarenite walls of vernacular building of Sassi show the excellent energy behavior of these constructions. But these material often present high moisture content which negatively influence the room microclimate in particular in presence of mural frescos and rocky churches. However these structures, once restored and in a condition of normal use, give indoor comfort within the limits of thermo-hygrometrics standards established by indices as the predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD).

    A novel non invasive technique and a suitable apparatus for disinfestation of artworks is introduced. Non destructive and non invasive techniques are often irreplaceable in order to preserve and restore cultural heritage objects in its structure and shape. Although many techniques are available for art and archaeological works the non invasive methods are preferred as they leave the object untouched after treatment. Environmental parameters, such as humidity, can damage culture heritage objects and also results in spring up variety of pests and other micro-organisms. Non-invasive monitoring of these damage and also disinfestation treatments and drying with help of electromagnetic waves are preferred as they keep the object untouched after treatment. Application of millimeter waves for solving this problem is discussed here. Millimeter waves have high spatial resolution and absorption in water as well as in bio-objects that are usually moist and at the same time minimal interaction with dry culture heritage objects by itself. Different phases of the microwaves treatment (MW) of artworks are described, some results are shown and discussed. Many biological forms don't survive over a certain temperature, called lethal temperature which, for most xylophages is about 53-55 degrees C, while for moulds and funguses is between 65 and 70 degrees C. In order to evaluate the management of disinfestation of works of art, incident power, temperature, exposure time were monitored. The monitoring of temperature is essential in order to prevent damages. A computer simulation allows to predict and monitor the heating process. PMID:24427872

    As the affordability, reliability and ease-of-use of Unmanned Aerial Vehicles (UAV) advances, the use of aerial surveying for cultural heritage purposes becomes a popular choice, yielding an unprecedented volume of high-resolution, geo-tagged image-sets of historical sites from above. As well, recent developments in photogrammetry technology provide a simple and cost-effective method of generating relatively accurate 3D models from 2D images. These techniques provide a set of new tools for archaeologists and cultural heritage experts to capture, store, process, share, visualise and annotate 3D models in the field. This paper focuses on the methodology used to document the cultural heritage site of Asinou Church in Cyprus using various state of the art techniques, such as UAV, photogrammetry and 3D printing. Hundreds of images of the Asinou Church were taken by a UAV with an attached high resolution, low cost camera. These photographic images were then used to create a digital 3D model and a 3D printer was used to create a physical model of the church. Such a methodology provides archaeologists and cultural heritage experts a simple and cost-effective method of generating relatively accurate 3D models from 2D images of cultural heritage sites.

    Inspired by the visionary idea of Digital Earth, as well as from the tremendous improvements in geo-technologies, use of virtual globes has been changing the way people approach to geographic information on the Web. Unlike the traditional 2D-visualization typical of Geographic Information Systems (GIS), virtual globes offer multi-dimensional, fully-realistic content visualization which allows for a much richer user experience. This research investigates the potential for using virtual globes to foster tourism and enhance cultural heritage. The paper first outlines the state of the art for existing virtual globes, pointing out some possible categorizations according to license type, platform-dependence, application type, default layers, functionalities and freedom of customization. Based on this analysis, the NASA World Wind virtual globe is the preferred tool for promoting tourism and cultural heritage. This is because its open source nature allows unlimited customization (in terms of both data and functionalities), and its Java core supports platform-independence. Relevant tourism-oriented World Wind-based applications, dealing with both the Web promotion of historical cartography and the setup of a participatory Web platform exploiting crowd-sourced data, are described. Finally, the paper presents a project focusing on the promotion of the Via Regina area (crossing the border between Italy and Switzerland) through an ad hoc World Wind customization. World Wind can thus be considered an ideal virtual globe for tourism applications, as it can be shaped to increase awareness of cultural history and, in turn, enhance touristic experience.

    observatory came up, as in the case of Nice Observatory, Hamburg-Bergedorf and in America. Finally the Schmidt telescope was the most important and influential invention in the Hamburg Observatory. In the last quarter of the 19th century only a few centres of astrophysics existed in the world. Besides Potsdam one should mention Göttingen, Heidelberg, Bonn and Hamburg in Germany; then observatories in Hungary, Italy, England and France and later, around 1900, also in the United States and India. The change from classical astronomy to modern astrophysics can be seen very well in the case of the Hamburg Observatory around 1900 - concerning the choice of instruments, the architecture and the idea of the astronomy park: all this is an important cultural heritage connected with observatories of this time.

    Several recording techniques are used together in Cultural Heritage Documentation projects. The main purpose of the documentation and conservation works is usually to generate geometric and photorealistic 3D models for both accurate reconstruction and visualization purposes. The recording approach discussed in this paper is based on the combination of photogrammetric dense matching and Terrestrial Laser Scanning (TLS) techniques. Both techniques have pros and cons, and criteria as geometry, texture, accuracy, resolution, recording and processing time are often compared. TLS techniques (time of flight or phase shift systems) are often used for the recording of large and complex objects or sites. Point cloud generation from images by dense stereo or multi-image matching can be used as an alternative or a complementary method to TLS. Compared to TLS, the photogrammetric solution is a low cost one as the acquisition system is limited to a digital camera and a few accessories only. Indeed, the stereo matching process offers a cheap, flexible and accurate solution to get 3D point clouds and textured models. The calibration of the camera allows the processing of distortion free images, accurate orientation of the images, and matching at the subpixel level. The main advantage of this photogrammetric methodology is to get at the same time a point cloud (the resolution depends on the size of the pixel on the object), and therefore an accurate meshed object with its texture. After the matching and processing steps, we can use the resulting data in much the same way as a TLS point cloud, but with really better raster information for textures. The paper will address the automation of recording and processing steps, the assessment of the results, and the deliverables (e.g. PDF-3D files). Visualization aspects of the final 3D models are presented. Two case studies with merged photogrammetric and TLS data are finally presented: - The Gallo-roman Theatre of Mandeure, France); - The

  5. Irrigation channels of the Upper Rhone valley (Switzerland). Geomorphological analysis of a cultural heritage

    NASA Astrophysics Data System (ADS)

    Reynard, Emmanuel

    2016-04-01

    The Upper Rhone valley (Canton of Valais, Switzerland) is characterised by dry climatic conditions that explain the presence of an important network (about 800 km) of irrigation channels - called Bisses in the French-speaking part of the canton or Suonen in the German-speaking area - dating back to the Middle Ages. This network constitutes a cultural heritage and during the last 30 years these agricultural infrastructures have sparked a renewed interest for tourist and cultural reasons. Indeed, the paths along the channels are used as tourist trails and several abandoned channels have been renovated for tourist use. Based on an inventory of the Bisses/Suonen of Valais, the proposed communication has three aims: (1) to analyse the geomorphological context (morphometric analysis, structural geomorphology, main processes) of various types of channels and to show the impact of the geomorphological context on the building techniques; (2) to identify particularly active processes along the channels; (3) to classify the Bisses/Suonen according to their geomorphological value and to their geomorphological sensitivity, and to propose managing measures. Structural and climatic conditions influence the geomorphological context of the channels. In a structural point of view, irrigation channels are developed in three main contexts: (1) in the Aar Massif crystalline basement; (2) in the limestone and marl cover nappes of the Helvetic Alps; (3) in the metamorphic cover nappes of the Penninic domain. The Rhone River valley is boarded by two high mountain ranges: the Penninic Alps in the South and the Bernese Alps in the North. Because of rain shadow effects, the climate is relatively dry and, between Brig and Martigny, annual rainfall is not more than 600 mm at 500 m ASL and 800 mm at 1600 m ASL. Nevertheless, due to important vertical precipitation gradients annual rainfall totals are high at high altitudes. On the southern facing tributary valleys, the dry climatic conditions

    An approach consisting in combining in situ and laboratory experiments is often favoured for investigating the mechanisms involved in the weathering of the materials of the cultural heritage. However, the realistic simulation in the laboratory of the environmental conditions ruling the interactions of atmospheric compounds with materials is a very complex task. The aim of this work is to characterise CIME, a new chamber specially built to simulate the interactions between materials of the cultural heritage and the environment. The originality of this instrument is that beside the usual climatic parameters (temperature, relative humidity, solar radiation) and gaseous pollutants, it also allows the controlled injection of different types of particulate matter such as terrigenous, marine and anthropogenic. Therefore, varied realistic atmospheric environments (marine or urban) can be easily simulated within CIME. In addition to the technical description of CIME, this paper shows the first results obtained by the impact of gaseous pollutants on non-durable glass, bronze and limestone. The first experiments for the deposition of different particles (calcite, clays, soot and halite) are also presented. PMID:26250811

    Terrestrial Laser Scanning (TLS), 3-D modeling and its Web visualization are the three key steps needed to perform storage and grant-free and wide access to cultural heritage, as highlighted in many recent examples. The goal of this study is to set up 3-D Web resources for "virtually" visiting the exterior of the Abbaye de l'Epau, an old French abbey which has both a rich history and delicate architecture. The virtuality is considered in two ways: the flowing navigation in a virtual reality environment around the abbey and a game activity using augmented reality. First of all, the data acquisition consists in GPS and tacheometry survey, terrestrial laser scanning and photography acquisition. After data pre-processing, the meshed and textured 3-D model is generated using 3-D Reshaper commercial software. The virtual reality visit and augmented reality animation are then created using Unity software. This work shows the interest of such tools in bringing out the regional cultural heritage and making it attractive to the public.

    Modern optical measuring systems are able to record objects with high spatial and spectral precision. The acquisition of spatial data is possible with resolutions of a few hundredths of a millimeter using active projection-based camera systems, while spectral data can be obtained using filter-based multispectral camera systems that can capture surface spectral reflectance with high spatial resolution. We present a methodology for combining data from these two discrete optical measuring systems by registering their individual measurements into a common geometrical frame. Furthermore, the potential for its application as a tool for the non-invasive monitoring of paintings and polychromy is evaluated. The integration of time-referenced spatial and spectral datasets is beneficial to record and monitor cultural heritage. This enables the type and extent of surface and colorimetric change to be precisely characterized and quantified over time. Together, these could facilitate the study of deterioration mechanisms or the efficacy of conservation treatments by measuring the rate, type, and amount of change over time. An interdisciplinary team of imaging scientists and art scholars was assembled to undertake a trial program of repeated data acquisitions of several valuable historic surfaces of cultural heritage objects. The preliminary results are presented and discussed.

    The pigment Prussian blue is studied in heritage science because of its capricious fading behavior under light exposure. We show here that XANES can be used to study the photosensitivity of Prussian blue heritage materials despite X-ray radiation damage. We used an original approach based on X-ray photochemistry to investigate in depth the redox process of Prussian blue when it is associated with a cellulosic substrate, as in cyanotypes and watercolors. By modifying cation and proton contents of the paper substrate, we could tune both rate and extent of Prussian blue reduction. These results demonstrate that the photoreduction and fading of Prussian blue is principally mediated by the substrate and its interaction with the oxygen of the environment.

    This paper present a 3D platform that enables to make both cultural heritage site survey and its virtual exploration. It provides a single and easy way to use framework for merging multi scaled 3D measurements based on photogrammetry, documentation produced by experts and the knowledge of involved domains leaving the experts able to extract and choose the relevant information to produce the final survey. Taking into account the interpretation of the real world during the process of archaeological surveys is in fact the main goal of a survey. New advances in photogrammetry and the capability to produce dense 3D point clouds do not solve the problem of surveys. New opportunities for 3D representation are now available and we must to use them and find new ways to link geometry and knowledge. The new platform is able to efficiently manage and process large 3D data (points set, meshes) thanks to the implementation of space partition methods coming from the state of the art such as octrees and kd-trees and thus can interact with dense point clouds (thousands to millions of points) in real time. The semantisation of raw 3D data relies on geometric algorithms such as geodetic path computation, surface extraction from dense points cloud and geometrical primitive optimization. The platform provide an interface that enables expert to describe geometric representations of interesting objects like ashlar blocs, stratigraphic units or generic items (contour, lines, … ) directly onto the 3D representation of the site and without explicit links to underlying algorithms. The platform provide two ways for describing geometric representation. If oriented photographs are available, the expert can draw geometry on a photograph and the system computes its 3D representation by projection on the underlying mesh or the points cloud. If photographs are not available or if the expert wants to only use the 3D representation then he can simply draw objects shape on it. When 3D

    The natural development of the Ústí region (North-West Bohemia, the Czech Republic) has been affected by the human activity during the past hundred years. The heavy industrialization and the brown coal mining have completely changed the land-use in the region. The open-pit coal mines are completely destroying the surrounding landscape, including settlement, communications, hydrological network and the over-all natural development of the region. The other factor affecting the natural development of the landscape, land-use and settlement was the political situation in 1945 (end of the 2nd World War) when the borderland was depopulated. All these factors caused vanishing of more than two hundreds of colonies, villages and towns during this period of time. The task of this project is to prepare and offer for public use a comprehensive information system preserving the cultural heritage in the form of processed old maps, aerial imagery, land-use and georelief reconstructions, local studies, text and photo documents covering the extinct landscape and settlement. Wide range of various maps was used for this area - Müller's map of Bohemia (ca. 1720) followed by the 1st, 2nd and 3rd Military survey of Habsburg empire (1792, 1894, 1938), maps of Stabile cadaster (ca. 1840) and State map derived in the scale 1:5000 (1953, 1972, 1981). All the maps were processed, georeferenced, hand digitized and are further used as base layers for visualization and analysis. The historical aerial imagery was processed in standard ways of photogrammetry and is covering the year 1938, 1953 and the current state. The other important task covered by this project is the georelief reconstruction. We use the old maps and aerial imagery to reconstruct the complete time-line of the georelief development. This time-line is covering the period since 1938 until now. The derived digital terrain models and further on analyzed and printed on a 3D printer. Other reconstruction task are performed using

    This research investigates the application of new system for 3D documentation of land degradation and its effect [1,2] on areas of cultural heritage via complete 3D data acquisition, 3D modeling and metadata recording using terrestrial laser scanners (TLS) [3,4,5]. As land degradation progresses through time it is important to be able to map and exactly replicate with great precision the entire 3D shape of the physical objects of interest, such as landslides, ground erosion, river boundaries, mad accumulation, etc. [1,2] TLS enables the extraction and recording of a very large number of points in space with great precision and without the need for any physical contact with the object of interest. Field specialists can then examine the produced models and comment on them both on the overall object of interest and on specific features of it by inserting annotations on certain parts of the model [6]. This process could be proven to be very cost effective as it can be repeated as often as necessary and produce a well catalogued documentation of the progress of land degradation at particular areas. The problem with repeating TLS models lies on the various types of hardware equipment and software systems that might be used for the extraction of point clouds, and the different people that might be called to analyze the findings. These often result in a large volume of interim and final products with little if no standardization, multiple different metadata and vague documentation [7], which makes metadata recordings [8] crucial both for one scientist to be able to follow upon the work of the other as well as being able to repeat the same work when deemed necessary. This makes the need for a repository tool proposed by the authors essential in order to record all work that is done in every TLS scanning, and makes the technology accessible to scientists of various different fields [9,10], eg. geologists, physicists, topographers, remote sensing engineers, archaeologists etc

    Life cycle management involves a seamless integration of materials, design, analysis, production, manufacturing, and degradation plus, a wide variety of disciplines relating to surveillance and characterisation with adequate feedback and control. Science and technology of non-destructive evaluation (NDE) links all these domains and disciplines together in a seamless and robust manner. A number of research programs on NDE science and technology have evolved during the last four decades world over including the one at Indira Gandhi Centre for Atomic Research, Kalpakkam, initiated and nurtured by the first author. Many engineering and technology challenges pertaining to fast spectrum reactors have been successfully solved by this Centre through development of innovative sensors, procedures and coupled with strong basic science and modeling approaches. These technologies have also been selectively applied in gaining insights of human health and cultural heritage. This paper highlights some of the innovative NDE sensors and techniques developed in the field of electromagnetic NDE and their successful applications. A few interesting case studies pertaining to NDE in heritage and healthcare using acoustic and thermal methods are also presented.

    Man has always had the need to live with his past, with its places and its artefacts. The reconstructions, the economical changes, the urbanization and its speculations have devastated whole cities, changed the faces of their historical centers, changed the relationship between the new and the old. Also the millenarian 'rest' of the archaeological findings, and therefore the respect towards those ancient civilizations, has been troubled. Our continent is rich in masterpieces that the modern man are not able to protect and pass on to the future, it is commonplace to observe that the modern `civilization' has cemented and suffocated the ancient city of Pompeii, or even worse, failed to protected it. Walking in the archaeological area of Paestum it can be noticed how just sixty years ago, no one had the slightest concern of fencing the amphitheatre and the Roman forum, or entire houses and shops, to lay a carpet of tar or simple to build constructions completely inferior compared to those majestic Greek temples. The engineers and the architects should be held responsible for this as based on their scientific and humanistic sensibility; they should bring together the man with his surroundings in the complete respects of the historical heritage. The interest in ancient began to change nearly three decades ago since it was realized that the "Cultural Heritage" is a major tourist attraction and, if properly managed and used, it can be an economical cornerstone. Today, thanks to survey and the 3D graphics, which provide powerful new tools, we are witnessing a new and real need for the conservation, cataloguing and enhancement as a way to revive our archaeological sites. As part of a major laboratory project, artefacts from the Roman period (I and II century b.C.), found in the Spanish city of Mérida, declared World Heritage by UNESCO in 1993, were acquired with a 3D laser scanner VIVID 910, and then catalogued. Based on these brief comments we wanted to direct the work

  18. Irrigation channels of the Upper Rhone valley (Switzerland). Geomorphological analysis of a cultural heritage

    NASA Astrophysics Data System (ADS)

    Reynard, Emmanuel

    2016-04-01

    The Upper Rhone valley (Canton of Valais, Switzerland) is characterised by dry climatic conditions that explain the presence of an important network (about 800 km) of irrigation channels - called Bisses in the French-speaking part of the canton or Suonen in the German-speaking area - dating back to the Middle Ages. This network constitutes a cultural heritage and during the last 30 years these agricultural infrastructures have sparked a renewed interest for tourist and cultural reasons. Indeed, the paths along the channels are used as tourist trails and several abandoned channels have been renovated for tourist use. Based on an inventory of the Bisses/Suonen of Valais, the proposed communication has three aims: (1) to analyse the geomorphological context (morphometric analysis, structural geomorphology, main processes) of various types of channels and to show the impact of the geomorphological context on the building techniques; (2) to identify particularly active processes along the channels; (3) to classify the Bisses/Suonen according to their geomorphological value and to their geomorphological sensitivity, and to propose managing measures. Structural and climatic conditions influence the geomorphological context of the channels. In a structural point of view, irrigation channels are developed in three main contexts: (1) in the Aar Massif crystalline basement; (2) in the limestone and marl cover nappes of the Helvetic Alps; (3) in the metamorphic cover nappes of the Penninic domain. The Rhone River valley is boarded by two high mountain ranges: the Penninic Alps in the South and the Bernese Alps in the North. Because of rain shadow effects, the climate is relatively dry and, between Brig and Martigny, annual rainfall is not more than 600 mm at 500 m ASL and 800 mm at 1600 m ASL. Nevertheless, due to important vertical precipitation gradients annual rainfall totals are high at high altitudes. On the southern facing tributary valleys, the dry climatic conditions

    Classroom-based primary prevention programs with adolescents are effective in inhibiting the onset of drug use, but these programs are not designed to directly address the unique needs of adolescents at higher risk of use or already using alcohol and other drugs. This article describes the initial efficacy evaluation of a companion psychosocial small group program which aims at addressing the needs of Mexican heritage students identified by their teachers as being at higher risk for substance use or already experimenting with alcohol and other drugs. The adolescent (7th grade) small group curricula, REAL Groups, is a secondary prevention program which supplements the primary classroom-based substance use prevention program, keepin' it REAL. Following a mutual aid approach, a total of 109 7th grade students were referred by their teachers and participated in the REAL Groups. The remaining 252 7th grade students who did not participate served as the control group. To account for biased selection into REAL Groups, propensity score matching (PSM) was employed. The estimated average treatment effect for participants' use of alcohol was calculated at the end of the 8th grade. Results indicate that alcohol use decreased among students who participated in the REAL Groups relative to matched students who did not participate. These findings suggest that REAL Groups may be an effective secondary prevention program for higher-risk Mexican heritage adolescents. PMID:22193861

    We describe the construction of an electrochemical cell of the Bragg type suitable for in situ synchrotron X-ray measurements on rough, heterogeneous metals such as cultural heritage alloys and simulants with corroding or passivated surfaces. The cell features a working electrode, which may be moved under remote control from a position close to an X-ray window to full immersion in the electrolyte. A pocket of electrolyte in contact with the bulk can be maintained on the working electrode surface at all times. Its thickness (typically 100-200 microm) can be controlled by adjusting the working electrode position and, independently, altering the conformation of the X-ray window with hydrostatic pressure. Alternatively, the electrode may be lowered into the bulk of the electrolyte. Early results from the cell showing a time-resolved study of the reduction of nantokite to cuprite in sodium sesquicarbonate, accompanied by corrosion potential measurements obtained in parallel, are presented here.

    A new approach for monitoring the state of conservation of cultural heritage objects surfaces is being developed. The technique utilizes multi-spectral imaging, multivariate analysis and statistical process control theory for the automatic detection of a possible deterioration process, its localization and identification, and the wavelengths most sensitive to detecting this before the human eye can detect the damage or potential degradation changes occur. A series of virtual degradation analyses were performed on images of parchment in order to test the proposed algorithm in controlled conditions. The spectral image of a Dead Sea Scroll (DSS) parchment, IAA (Israel Antiquities Authority) inventory plate # 279, 4Q501 Apocryphal Lamentations B, taken during the 2008 Pilot of the DSS Digitization Project, was chosen for the simulation.

    The workgroup for Digital Reconstruction of the Digital Humanities in the German-speaking area association (Digital Humanities im deutschsprachigen Raum e.V.) was founded in 2014 as cross-disciplinary scientific society dealing with all aspects of digital reconstruction of cultural heritage and currently involves more than 40 German researchers. Moreover, the workgroup is dedicated to synchronise and foster methodological research for these topics. As one preliminary result a memorandum was created to name urgent research challenges and prospects in a condensed way and assemble a research agenda which could propose demands for further research and development activities within the next years. The version presented within this paper was originally created as a contribution to the so-called agenda development process initiated by the German Federal Ministry of Education and Research (BMBF) in 2014 and has been amended during a joint meeting of the digital reconstruction workgroup in November 2014.

    Many important Cultural Heritage sites have been studied over long periods of time by different means of technical equipment, methods and intentions by different researchers. This has led to huge amounts of heterogeneous "traditional" datasets and formats. The rising popularity of 3D models in the field of Cultural Heritage in recent years has brought additional data formats and makes it even more necessary to find solutions to manage, publish and study these data in an integrated way. The MayaArch3D project aims to realize such an integrative approach by establishing a web-based research platform bringing spatial and non-spatial databases together and providing visualization and analysis tools. Especially the 3D components of the platform use hierarchical segmentation concepts to structure the data and to perform queries on semantic entities. This paper presents a database schema to organize not only segmented models but also different Levels-of-Details and other representations of the same entity. It is further implemented in a spatial database which allows the storing of georeferenced 3D data. This enables organization and queries by semantic, geometric and spatial properties. As service for the delivery of the segmented models a standardization candidate of the OpenGeospatialConsortium (OGC), the Web3DService (W3DS) has been extended to cope with the new database schema and deliver a web friendly format for WebGL rendering. Finally a generic user interface is presented which uses the segments as navigation metaphor to browse and query the semantic segmentation levels and retrieve information from an external database of the German Archaeological Institute (DAI).

    The traditional methodology used for the identification of microbes colonizing our cultural heritage was the application of cultivation methods and/or microscopy. This approach has many advantages, as living microorganisms may be obtained for physiological investigations. In addition, these techniques allow the quantitative and qualitative assessment of the investigated environment. Quantitative analyses are done by plate count and the determination of abundance by the colony forming unit (CFU). Nevertheless, these techniques have many drawbacks that lead to an underestimation of the cell numbers and do not provide a comprehensive overview of the composition of the inhabiting microbiota. In the last decades, several molecular techniques have been developed enabling many advantages over the cultivation approach. Mainly PCR-based, fingerprinting techniques allow a qualitative detection and identification of the microbiota. In this study, we developed a real time PCR method as a simple, rapid and reliable tool to detect and quantify fungal abundance using the β-actin gene, which is known to appear as a single-copy gene in fungi. To this end, five different indoor thermal insulation materials applied for historical buildings that were previously tested for their bio-susceptibility against various fungi were subjected to qPCR analyses. The obtained results were compared with those obtained from a previous study investigating the bio-susceptibility of the insulation materials using classical cultivation experiments. Both results correlated well, revealing that Perlite plaster was the most suitable insulation material, showing the lowest fungal CFU and qPCR values. In contrast, insulations made of wood showed to be not recommendable from the microbiological point of view. In addition, the potential of qPCR was tested in other materials of cultural heritage, as old parchments, showing to be a suitable method for measuring fungal abundance in these delicate materials.

  11. Nanostructure and irreversible colloidal behavior of Ca(OH)2: implications in cultural heritage conservation.

    Although Ca(OH)2 is one of the oldest art and building material used by mankind, little is known about its nanostructural and colloidal characteristics that play a crucial role in its ultimate performance as a binder in lime mortars and plasters. In particular, it is unknown why hydrated lime putty behaves as an irreversible colloid once dried. Such effect dramatically affects the reactivity and rheology of hydrated lime dispersions. Here we show that the irreversible colloidal behavior of Ca(OH)2 dispersions is the result of an oriented aggregation mechanism triggered by drying. Kinetic stability and particle size distribution analysis of oven-dried slaked lime or commercial dry hydrate dispersions exhibit a significant increase in settling speed and particle (cluster) size in comparison to slaked lime putty that has never been dried. Drying-related particle aggregation also leads to a significant reduction in surface area. Electron microscopy analyses show porous, randomly oriented, micron-sized clusters that are dominant in the dispersions both before and after drying. However, oriented aggregation of the primary Ca(OH)2 nanocrystals (approximately 60 nm in size) is also observed. Oriented aggregation occurs both before and during drying, and although limited before drying, it is extensive during drying. Nanocrystals self-assemble in a crystallographically oriented manner either along the 100 or equivalent 110 directions, or along the Ca(OH)2 basal planes, i.e., along [001]. While random aggregation appears to be reversible, oriented aggregation is not. The strong coherent bonding among oriented nanoparticles prevents disaggregation upon redispersion in water. The observed irreversible colloidal behavior associated with drying of Ca(OH)2 dispersions has important implications in heritage conservation, particularly considering that nowadays hydrated lime is often the preferred alternative to portland cement in architectural heritage conservation. Finally, our

    Natural organic substances are involved in many aspects of the cultural heritage field. Their presence in different forms (raw, heated, mixed), with various conservation states, constitutes a real challenge regarding their recognition and discrimination. Their characterization usually involves the use of separative techniques which imply destructive sampling and specific analytical preparations. Here we propose a non destructive approach using FT-Raman and infrared spectroscopies for the identification and differentiation of natural organic substances. Because of their related functional groups, they usually present similar vibrational signatures. Nevertheless the use of appropriate signal treatment and statistical analysis was successfully carried out to overcome this limitation, then proposing new objective discriminating methodology to identify these substances. Spectral decomposition calculations were performed on the CH stretching region of a large set of reference materials such as resins, oils, animal glues, and gums. Multivariate analyses (Principal Component Analyses) were then performed on the fitting parameters, and new discriminating criteria were established. A set of previously characterized archeological resins, with different surface aspects or alteration states, was analyzed using the same methodology. These testing samples validate the efficiency of our discriminating criteria established on the reference corpus. Moreover, we proved that some alteration or ageing of organic materials is not an issue to their recognition. PMID:24054630

    It is common to modify valuable, sophisticated equipment, originally acquired for other purposes, to adapt it for the needs of educational experiments, with great didactic effectiveness. The present project concerns a setup developed from components of a portable system for energy dispersive x-ray fluorescence spectroscopy (EDXRF). Two educational modules have been developed on the basis of this setup. Module 1 comprises a series of x-ray laboratory exercises investigating basic principles, such as the verification of Moseley's law, Compton's law and the Lambert-Beer law. Module 2 concerns the calibration of the XRF with reference materials, aiming to get quantitative measurements of the elemental composition of objects of cultural interest. The application of the calibrated experimental setup is demonstrated with indicative measurements of metal objects and pigments of wall paintings, in order to discuss their spectra, and their qualitative and quantitative analyses. The setup and the applied experiments are designed as an educational package of laboratory exercises on the one hand for students in natural sciences, and on the other for the education of students who will work in the field of cultural heritage, such as conservation science or archaeological science.

    2009-01-01

    The Cappadocia region is one of the most important tourism centers of Turkey owing to its natural beauty and historical heritage. The natural landscapes predominantly contribute to the tourism capacity of the region. This is controlled directly by the characteristic lithological units and surface processes. However, rockfall events, which are sometimes observed in the region, are typical natural hazards conditioned by discontinuities, steep topography and human activities. The Ortahisar Castle is one of the natural monuments and also one of the historical places of this region. This castle is located on a steep hill formed by jointed ignimbrite and its height and settlement area are approximately 50 m and 500 m2, respectively. However, some blocks on the castle have begun to exhibit serious rockfall potential. Rock hewn structures carved by man for various purposes contribute to increase in rockfall hazard. For this reason, the castle was closed to touristic visits. The purpose of this study was to evaluate this hazard potential and perform a series of rockfall analyses and discuss the results. Besides, location and dimension of fallen blocks were determined. At the final stage of the fieldwork, location and size of detached blocks having potential to fall were described. During the analysis stage, runout distance, bounce height, kinetic energy and velocity of the detached blocks were determined by using Rocfall V.4 software. The results obtained from rockfall analyses were used to map the areas under rockfall threat in the close vicinity of the castle and the potential risk was interpreted.

    Seismic hazard is among the main factors conditioning the conservation of historical centres and cultural heritage located in them. This consideration is suitable especially for downtown areas located in Italy, whose territory is prone to seismic hazards, in the southern area especially. As a matter of fact, the historical sources inform us that most of monuments located in Southern Italy suffered damage and consequent restoration or rebuilding due to the earthquake of the past. Therefore, knowing what buildings are the most exposed to the seismic risk can help the stakeholders to fix priority actions aimed at mitigating the effects of future events. Starting from these preliminary remarks, in the framework of the Project PRO_CULT, we started an extensive campaign of measurements of dynamic features of the church towers in some towns of the Basilicata Region (Southern Italy). The aim of the research activity is to assess the fundamental period of such a typology of historical buildings and comparing it with the dynamic features of the foundation soil to put into evidence possible resonance phenomena responsible of an increase of building damage during the seismic shaking. The selection of the towns to be considered as a target of the experimental survey was performed taking into account the availability of written sources dealing with the historical seismic effects suffered by the bell-towers over the centuries with special attention to the sites heavily affected by the 16 December 1857 Basilicata and 23 November 1980 Irpinia-Basilicata earthquakes (Gizzi and Masini 2007). The fundamental period of bell-towers is estimated using ambient noise vibration signals recorded at the highest level of the towers. The techniques used to get the dynamic values are both the Horizontal to Vertical Spectral Ratio (HVSR) and the Horizontal to Horizontal Spectral Ratio (HHSR) (Liberatore et al. 2008). Once the fundamental frequency has been estimated, it is compared with the

    When attempting to discuss the effects of airborne particulate matter (PM), it is important to address both physical and chemical aspects of this pollutant. This work reports on the results of three separate case studies, each approaching a specific problem of air pollution by evaluating the chemical composition of PM. 1. In the US and Europe, office workers often complain about work-related health symptoms. These symptoms are collectively referred as the 'sick building syndrome'. This work could be considered as one of the largest data collections on particulate pollutants in Belgian offices. It helps to understand the sources as well as the behavior and fate of PM at our workplace environments. Especially the chemical information on PM makes the results unique, since it enables a better evaluation of the health risks connected to office dust. 2. The Alhambra and Generalife bring every year more than 3 million people to Granada in Southern Spain. Recently, the increasing urbanization of Granada and the immense pressure of mass tourism form a threat for this heritage. Despite the fact that atmospheric pollutants are known to he potentially aggressive for our cultural patrimony. this case study is the first to assess the effects of environmental aerosols on the Alhambra monument. The results of this study could help decision-makers at the Alhambra and the city of Granada with the formulation of preventive conservation measures. They show how local vehicular traffic is the main source for atmospheric pollution in and around the Alhambra monument. Targeted strategies are necessary in order to maximally preserve these monuments and their UNESCO world cultural heritage label. 3. Excessive input of nitrogen-containing atmospheric nutrients via dry and wet deposition can cause entrophication of marine regions, which is also a common, seasonal phenomenon along the coasts of the North Sea.

    This work presents a case study based on results of monitoring campaigns developed in San Juan Bautista church in Talamanca de Jarama (Madrid, Spain). This Church was built in the twelfth-thirteenth centuries (Romanesque style) with dolostone ashlars. It was reconstructed in the sixteenth century (Renaissance style) with rubble stone and mortar, brick and an earth fill. Different sections on walls and floors (north and south oriented) have been selected based on a preliminary study of moisture distribution on stone and masonry wall. The behavior of different materials has been studied according to the influence of indoor (microclimatic conditions) and outdoor conditions (weather conditions) and taking into account constructive facts. Several sensing technologies as dataloggers and wireless sensor networks (WSN) together to other non invasive techniques as thermal imaging, portable moisture meter, electrical resistivity tomography (ERT) and ground-penetrating radar (GPR) have been conducted. By means of this study it has been possible to establish an analysis methodology to determine the dampness origin in each case. Conclusions related to the each technique according to its effectiveness in the detection of decay problems have been established.

    The aim of this contribution is to show the results of evaluations on 3D digitizations performed using different methodologies and technologies. In particular, for surveys conducted at the architectural and urban scale, the recent reduction of costs related to Time of Flight and phase shift laser scanners is actually enhancing the replacement of traditional topographic instruments (i.e. total stations) with range-based technologies for the acquisition of 3D data related to built heritage. If compared to surveys performed using traditional topographic technologies, range-based ones offer a wide range of advantages, but they also require different skills, procedures and times. The present contribution shows the results of a practical application of both approaches on the same case study. Another application was suggested by the recent developments in the photogrammetric field that enhance the improvement of software able to automatically orient uncalibrated cameras and derive dense and accurate 3D point clouds, with evident benefits in reduction of costs required for survey equipment. Therefore, the presented case study constituted the occasion to compare a rangebased survey with a fast 3D acquisition and modelling using a Structure from Motion solution. These survey procedures were adopted at an architectural scale, on a single building, that was surveyed both on the outside and on the inside. Assessments on the quality of the rebuilt information is reported, as far as metric accuracy and reliability is concerned, as well as on time consuming and on skills required during each step of the adopted pipelines. For all approaches, these analysis highlighted advantages and disadvantages that allow to conduct evaluations on the possible convenience of adopting range-based technologies instead of a traditional topographic approach or a photogrammetric one instead of a range based one in case of surveys conducted at an architectural/urban scale.

  1. Safeguard of Cultural Heritage: Evaluation of Ground Motion at Palazzo Te (Mantova, Italy)

    Built on the first half of the XVI century, under Federico II Gonzaga, Duke of Mantova, Palazzo Te is one of the most relevant Italian monuments and it belongs to the UNESCO World Heritage List; the Camera dei Giganti (Chamber of the Giants) hosts a famous XVI century Giulio Romano fresco. Palazzo Te raises concerns in particular for the statics of the Fruttiere external wall and for some fissures that cross the above mentioned fresco. Therefore a monitoring survey has been undertaken to detect and qualify the vibrations caused by earthquakes and anthropic activity. Palazzo Te is situated in a low seismicity area, nevertheless even weak earthquakes could result in significant damage due to the poor soil conditions. A seismic station deployed inside the Palazzo Te recorded, on July 17, 2011, 2 cm/sec2 PGA for the ML 4.7 earthquake located at approx 51 km distance: some light damage has been observed. As far as vibrations due to anthropic origin, the station has evidenced that the major threat is due to the trains at the nearby railway: inside the Palazzo Te PGA reached 5 cm/sec2. The seismic survey led to the following considerations: 1. even low magnitude earthquakes can be a threat, given the intrinsic vulnerability of some parts of the Palazzo Te; 2. the main and possibly unique significant dangerous vibrations of anthropic origin come from the trains running nearby; 3. the response spectra evidenced that the earthquake had a consistent energy content till T0=2 seconds, while the spectrum of the trains decay abruptly at around 10 Hz. In contrast the train response spectrum is significantly higher in the high frequency range. In conclusion, despite the relatively low hazard, seismic risk is still relevant, because of the poor soil conditions coupled with the high vulnerability. The train vibrations are not a threat for the Palazzo Te structure but can cause some concerns to the frescoes.

    This research investigates the application of new system for 3D documentation of land degradation and its effect [1,2] on areas of cultural heritage via complete 3D data acquisition, 3D modeling and metadata recording using terrestrial laser scanners (TLS) [3,4,5]. As land degradation progresses through time it is important to be able to map and exactly replicate with great precision the entire 3D shape of the physical objects of interest, such as landslides, ground erosion, river boundaries, mad accumulation, etc. [1,2] TLS enables the extraction and recording of a very large number of points in space with great precision and without the need for any physical contact with the object of interest. Field specialists can then examine the produced models and comment on them both on the overall object of interest and on specific features of it by inserting annotations on certain parts of the model [6]. This process could be proven to be very cost effective as it can be repeated as often as necessary and produce a well catalogued documentation of the progress of land degradation at particular areas. The problem with repeating TLS models lies on the various types of hardware equipment and software systems that might be used for the extraction of point clouds, and the different people that might be called to analyze the findings. These often result in a large volume of interim and final products with little if no standardization, multiple different metadata and vague documentation [7], which makes metadata recordings [8] crucial both for one scientist to be able to follow upon the work of the other as well as being able to repeat the same work when deemed necessary. This makes the need for a repository tool proposed by the authors essential in order to record all work that is done in every TLS scanning, and makes the technology accessible to scientists of various different fields [9,10], eg. geologists, physicists, topographers, remote sensing engineers, archaeologists etc

    Ground Penetrating Radar (GPR) is a safe, non-destructive and non-invasive imaging technique that can be effectively used for advanced inspection of composite structures and for diagnostics affecting the whole life-cycle of civil engineering works. GPR can also be successfully employed in archaeological prospecting and cultural heritage diagnostics. In many Countries, where the archeological patrimony is an outstanding value (as Egypt, Israel, Greece, Central and South America), GPR is usually employed both as a diagnostic tool for the preventive detection of archeological structures and as the most advanced instrument able to prospect geometry and shape of underground valuable sites. However many uncertainties persist, because of several difficulties and ambiguities due to the complexity of the image processing in heterogeneous environment. It is possible to identify three main areas, in GPR field, that have to be addressed in order to promote the use of this technology in archaeological prospecting and cultural heritage diagnostics. These are: a) increase of the system sensitivity to enable the usability in a wider range of conditions, archeological sites are often located in impervious and critical environments; b) research novel data processing algorithms/analysis tools for the interpretation of GPR results; c) contribute to the development of new standards and guidelines and to training of end users, that will also help to increase the awareness of operators. It is also important to further investigate and promote a combined use of GPR with other non-invasive advanced techniques, typically used in the archeological investigation. In this framework, the COST Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar", proposed by a research team of "Roma Tre" University, Rome, Italy, has been approved in November 2012 and is going to start in April 2013. It is a 4-years ambitious project already involving 17 European Countries (AT, BE, CH, CZ, DE

  4. Calendar Pluralism and the Cultural Heritage of Domination and Resistance (Tuareg and Other Saharans)

    NASA Astrophysics Data System (ADS)

    Oxby, Clare

    This article is about Saharan calendars from precolonial times to the present. It shows that multiple calendar use has been a constant feature throughout the centuries, that the distinction between indigenous and imported has little meaning in this region of long-standing cultural exchange, and that many Saharan communities still simultaneously use differing official state, literate specialist, and local popular calendars. Social and political explanations of calendar pluralism are presented, contrasting the center view whereby calendars constitute a means of social control and the periphery view whereby communities may affirm their cultural autonomy through particular calendar choices.

    A wide ranging R&D Project (ISTECH) on validation and application of the Innovative Antiseismic Techniques (IATs) for the restoration of Cultural Heritage Structures (CUHESs), especially masonry buildings, based on the Shape Memory Alloys (SMAs), has been funded by the European Commission (EC), in the framework of the Environment and Climate RTD Programme. Because Traditional Restoration Techniques (TRTs) have sometimes proved inadequate in avoiding collapses and often too invasive, the use of superelastic SMA Devices (SMADs) has been developed. Theoretical and numerical studies, as well as intensive testing of material specimens, devices, structural models and in situ campaigns, show that SMADs can substantially increase the stability of masonry CUHESs exposed to an earthquake. Different SMAD types have been investigated to fulfil different structural needs and they can be custom designed taking into account each monument's characteristics. The successful results of the research and its exploitation led to important applications in Italy: the S. Giorgio Church Bell-Tower, located at Trignano, S. Martino in Rio, Reggio Emilia, damaged by the 15th October 1996 earthquake, the transept tympana of the S. Francesco Basilica in Assisi and the S. Feliciano Cathedral façade in Foligno, both heavily damaged by the September 1997 earthquake. In addition, further studies and applications of SMAD technology are foreseen in Italy in the next future, in the framework of Italian and European research projects and proposals.

    Though the phenomenon of scientific tourism is widely spread in the USA and Europe, it is a new branch in Armenian tourism. The aim of the scientific tourism is to establish relationship between the tourist and the scientist, without the tourist having any material interest. The main aim is to involve the tourist in the scientific works, giving him a chance to be a part of the expedition. One of the main goals is also to involve the local tourist in the exploration of the historical and cultural heritage. It is important to mention that besides having the chance to take part in the scientific exploration, they also enjoy the time. It gives an opportunity to make the relation between the tourist and the scientist more strengthen, and let them partnering for future. The scientific tourism gives the scientist an opportunity to get new volunteers to make it wide known for the society. What refers to a tourist it is a good chance for him to be a part of a scientific exploration, to satisfy his own interest, to get new knowledge, and take part in the development of his own country.

    The paper presents a project aiming to develop a knowledge-based system for documentation and analysis of defects of cultural heritage objects and monuments. The MONDIS information system concentrates knowledge on damage of immovable structures due to various causes, and preventive/remedial actions performed to protect/repair them, where possible. The currently built system is to provide for understanding of causal relationships between a defect, materials, external load, and environment of built object. Foundation for the knowledge-based system will be the systemized and formalized knowledge on defects and their mitigation acquired in the process of analysis of a representative set of cases documented in the past. On the basis of design comparability, used technologies, materials and the nature of the external forces and surroundings, the developed software system has the capacity to indicate the most likely risks of new defect occurrence or the extension of the existing ones. The system will also allow for a comparison of the actual failure with similar cases documented and will propose a suitable technical intervention plan. The system will provide conservationists, administrators and owners of historical objects with a toolkit for defect documentation for their objects. Also, advanced artificial intelligence methods will offer accumulated knowledge to users and will also enable them to get oriented in relevant techniques of preventive interventions and reconstructions based on similarity with their case.

  16. From socialist ideology to cultural heritage: the changing basis of legitimacy in the People's Republic of China.

    PubMed

    Madsen, Richard

    2014-01-01

    There has been a shift over the past generation in the moral basis for legitimacy of the Chinese state. The socialist state was legitimated by a sinified version of Marxism-Leninism, watered with the blood of revolutionary martyrs who fought on behalf of the Communist Party to defend the nation from external aggressors. However, at many levels of society, the Marxist legitimation is dead. Instead of claiming to represent the values of Communist revolutionary struggle in the twentieth century, the state is now presenting itself as the carrier and the defender of 5000 years of national cultural heritage. This undoubtedly arises partly from changes in moral attitude arising from the grass roots and partly from government initiatives descending from the top down. There is wide variation across China in the intermingling between the bottom-up and top-down moral impulses, and this is partially connected with different moral ecologies constituted by configurations of state and local political and economic institutions throughout China. In this paper, based on case studies from fieldwork carried out in several different locations in 2009, the author draws a broad map of these variations. PMID:24564490

  17. The Representation of Cultural Heritage from Traditional Drawing to 3d Survey: the Case Study of Casamary's Abbey

    In 3D survey the aspects most discussed in the scientific community are those related to the acquisition of data from integrated survey (laser scanner, photogrammetric, topographic and traditional direct), rather than those relating to the interpretation of the data. Yet in the methods of traditional representation, the data interpretation, such as that of the philological reconstruction, constitutes the most important aspect. It is therefore essential in modern systems of survey and representation, filter the information acquired. In the system, based on the integrated survey that we have adopted, the 3D object, characterized by a cloud of georeferenced points, defined but their color values, defines the core of the elaboration. It allows to carry out targeted analysis, using section planes as a tool of selection and filtering data, comparable with those of traditional drawings. In the case study of the Abbey of Casamari (Veroli), one of the most important Cistercian Settlement in Italy, the survey made for an Agreement with the Ministry of Cultural Heritage and Activities and Tourism (MiBACT) and University of RomaTre, within the project "Accessment of the sismic safety of the state museum", the reference 3D model, consisting of the superposition and geo-references data from various surveys, is the tool with which yo develop representative models comparable to traditional ones. It provides the necessary spatial environment for drawing up plans and sections with a definition such as to develop thematic analysis related to phases of construction, state of deterioration and structural features.

    One of the main tools of assessment and diagnosis used to define appropriate strategies for the preservation of cultural heritage is the environmental monitoring. To achieve an environmental monitoring are needed high costs of purchase and maintenance, high costs of instrumental and for the management of the plants and processing of results. These costs imply that the technologies for environmental monitoring are not as common but their use is limited to the study very famous monuments or sites. To extend the use and dissemination of such technologies to a greater number of monuments, through the project Pro_Cult (Advanced methodological approaches and technologies for Protection and Security of Cultural Heritage) a research aimed at testing low cost technologies has been performed. The aim of the research is to develop low cost monitoring systems, assessing their effectiveness in a comparative way with commercial high cost ones. To this aim an environmental monitoring system using the Arduino system was designed and developed. It is an electronics prototyping platform based on open-source hardware and software flexible and user friendly. This system is connected to sensors for the detection of environmental parameters of non high purchase cost but with respect to the medium potential detection sensors accurately. This low cost system was tested in the framework of a microclimate monitoring project of the crypt of St. Francis of Assisi in Irsina (Southern Italy) enriched by a precious cycle of medieval frescoes. The aim of this research was to compare two monitoring systems, the first, at low cost, using Arduino system, and the second, a standard commercial product for a full yearly cycle and assess the reliability and the results obtained by the two systems. This paper shows the results of the comparative analysis of an entire monitoring yearly cycle in relation to the problems of degradation affecting the paintings of medieval crypt [1].

  1. Recording Cultural Heritage Using Terrestrial Laserscanning - Dealing with the System, the Huge Datasets they Create and Ways to Extract the Necessary Deliverables you can Work with

    Christofori, E.; Bierwagen, J.

    2013-07-01

    Recording Cultural Heritage objects using terrestrial laserscanning becomes more and more popular over the last years. Since terrestrial Laserscanning System (TLS) Manufacturers have strongly increased the amount and speed of data captured with a single scan at each system upgrade and cutting down system costs the use of TLS Systems for recording cultural heritage is an option for recording worth to think about beside traditional methods like Photogrammetric. TLS Systems can be a great tool for capturing complex cultural heritage object within a short amount of time beside the traditional methods but can be a nightmare to handle for further process if not used right while capturing. Furthermore TLS Systems still have to be recognized as survey equipment, even though some of the manufactures promote them as everyday tool. They have to be used in an intelligent way having in mind the clients and the individual cultural objects needs. Thus the efficient way to use TLS Systems for data recording becomes a relevant topic to deal with the huge Amount of data the Systems collect while recording. Already small projects can turn into huge Pointcloud Datasets that End user, like Architects or Archaeologist neither can't deal with as their technical equipment doesn't fit the requirements of the Dataset nor do they have the software tools to use the Data as the current software tools still are high prized. Even the necessary interpretation of the Dataset can be a tough task if the people who have to work on with the Pointcloud aren't educated right in order to understand TLS and the results it creates. The use of TLS Systems has to have in mind the project requirements of the individual Heritage Object, like the required accuracy, standards for Levels of Details (e.g. "Empfehlungen für die Baudokumentation, Günther Eckstein, Germany"), the required kind of Deliverables (Visualization, 2D Drawings, True Deformation Drawings, 3D Models, BIM or 4D - Animations) as well as the

  2. The Lowland Rivers of The Netherlands - Geodiversity and Cultural Heritage on 19th and early 20th century Landscape Paintings

    One of the major Dutch landscapes is formed by lowland rivers. They divide the country in a southern and a northern part, both physically and culturally. We screened the freely available database of 19th and early 20th century paintings of Simonis & Buunk, www.simonis-buunk.com, looking for lowland river landscapes depicting geodiversity and cultural heritage relationships (See References for other landscapes). Emperor Napoleon declared The Netherlands as naturally belonging to his empire as its lands originated from muds originating in France and transported there by the big rivers. A description that may have given rise to the idea of the Netherlands as a delta, but from a geomorphological perspective The Netherlands consists of series of river plains of terrestrial origin, of which the north-western part are subsiding and invaded by the sea. Now, the rivers Meuse and Rhine (including its branches Waal and IJssel) meander through ever larger river plains before reaching the North Sea. They end in estuaries, something one would not expect of rivers with catchments discharging a large part of Western Europe. Apart from the geological subsidence, the estuaries might be due to human interference, the exploitation of peat and building of dikes since the 11th century, heavy storms and the strong tidal currents. Archaeological finds show Vikings and Romans already used the river Rhine system for trading and transporting goods. During the Roman Empire the Rhine was part of The Limes, the northern defence line of the empire. Romans already influenced the distribution of water over the different river branches. Since the middle of the 19th century groins and canalization drastically changed the character of the rivers. The 19th and early 20th century landscape paintings illustrate this change as well as changes in land use. Examples of geodiversity and cultural heritage relationships shown: - meanders and irregular banks disappear as river management increases, i.a. bends

  3. NMR spectroscopy applied to the Cultural Heritage: a preliminary study on ancient wood characterisation

    Viel, S.; Capitani, D.; Proietti, N.; Ziarelli, F.; Segre, A. L.

    High and low resolution solid state NMR methods have been applied to characterise a few samples of ancient wood. In an ancient larch wood sample, by applying 1H low resolution NMR methods as a function of the temperature, the average pore size and its distribution have been determined. In addition, high resolution NMR techniques have allowed addressing of the question of the proximity of water pools to cellulose and lignin. In particular, a model can be hypothesized in which water pools are surrounded by thin layers of amorphous cellulose and/or lignin while the crystalline domains of cellulose surround the layers of amorphous cellulose. Preliminary results obtained using a fully non invasive and portable NMR unilateral relaxometer, the Eureka-Mouse10 (EM10), are reported. This instrumentation is shown to be perfectly suitable for characterizing degradation in ancient wood samples.

    2012-10-01

    South Africans have a long association with water. It has provided a source of food, a medium for trade and a catalyst for migration and development. The country's geographical position as a crossroads of maritime trade between Europe and the East means that its history is inextricably linked to the history of the rest of the world. The result is a multi-faceted representation of sites, objects and mythologies related to water and maritime heritage that reflect not only local historical and social development, but global cultural change as well. Given the importance of South Africa's underwater cultural heritage (UCH), managers have grappled with management principles, ethics and theoretical models in an effort to produce and enforce heritage legislation that is relevant and effective. This paper outlines South Africa's maritime context from 1.5 million years ago until the present, summarises legislative and mitigation developments over the past half century and provides details of current trends in maritime archaeology and UCH management at the southern tip of Africa. Training programmes and public awareness are keys to this strategy to bring UCH and maritime archaeology into the mainstream and counter treasure hunting and looting of this rich, friable resource.

    2014-01-01

    Since ages, architects and artists worldwide have focused on usage of durable stones as marble and limestone for construction of beautiful and magnificent historic monuments as European Cathedrals, Roman, and Greek temples, Taj Mahal etc. But survival of these irreplaceable cultural and historical assets is in question these days due to their degradation and deterioration caused by number of biotic and abiotic factors. These causative agents have affected not only the esthetic appearance of these structures, but also lead to deterioration of their strength and durability. The present review emphasizes about different causative agents leading to deterioration and application of microbially induced calcium carbonate precipitation as a novel and potential technology for dealing with these problems. The study also sheds light on benefits of microbial carbonate binders over the traditional agents and future directions. PMID:25018751

    Culturable bacterial abundance at 11 different depths of a 50.26 m ice core from the Tallaksenvarden Nunatak, Antarctica, varied from 0.02 to 5.8 × 10(3) CFU ml(-1) of the melt water. A total of 138 bacterial strains were recovered from the 11 different depths of the ice core. Based on 16S rRNA gene sequence analyses, the 138 isolates could be categorized into 25 phylotypes belonging to phyla Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. All isolates had 16S rRNA sequences similar to previously determined sequences (97.2-100%). No correlation was observed in the distribution of the isolates at the various depths either at the phylum, genus or species level. The 25 phylotypes varied in growth temperature range, tolerance to NaCl, growth pH range and ability to produce eight different extracellular enzymes at either 4 or 18 °C. Iso-, anteiso-, unsaturated and saturated fatty acids together constituted a significant proportion of the total fatty acid composition. PMID:23041141

  7. Cultural Heritage Protection Issues In Leśnica, The Settlement Of Wrocław

    NASA Astrophysics Data System (ADS)

    Kononowicz, Alena

    2015-09-01

    Leśnica, today the settlement on the western edge of Wrocław, formerly was an independent town, located on a previously wooded area, with a linear street system. It developed in the Middle Ages around the castle and church playing a service role for the Silesian Piast court on their way to Legnica and during hunting. In the thirteenth century it received city rights, and lost them in the eighteenth century. After the Piast dynasty had died out, it was sold by John of Luxembourg, and repeatedly changed its owners. In the nineteenth century it developed thanks to the industry, tourism and a convenient railway connection to Wrocław as well as hotel and restaurant facilities. In 1928, Leśnica was incorporated into Wrocław. After the Second World War, it lost its cultural continuity. In the 1970's, middle-heigh and high prefabricated buildings were built in the vicinity of a residential district. At the end of the twentieth and early twenty-first century, local industries were liquidated, and intensive land development started, causing the systematic blurring of its small-town character and its urban space started to acquire a character of a big city. In 2004, the old part of Leśnica was entered in the Register of Monuments. Also a ring road was planned, moving the cumbersome and dangerous transit traffic away from historic Średzka Street beyond the southern border of the settlement.

    Existing chemical treatments to prevent biological damage to monuments often involve considerable amounts of potentially dangerous and even poisonous biocides. The scientific approach described in this paper aims at a drastic reduction in the concentration of biocide applications by a polyphasic approach of biocides combined with cell permeabilisers, polysaccharide and pigment inhibitors and a photodynamic treatment. A variety of potential agents were screened to determine the most effective combination. Promising compounds were tested under laboratory conditions with cultures of rock deteriorating bacteria, algae, cyanobacteria and fungi. A subsequent field trial involved two sandstone types with natural biofilms. These were treated with multiple combinations of chemicals and exposed to three different climatic conditions. Although treatments proved successful in the laboratory, field trials were inconclusive and further testing will be required to determine the most effective treatment regime. While the most effective combination of chemicals and their application methodology is still being optimised, results to date indicate that this is a promising and effective treatment for the control of a wide variety of potentially damaging organisms colonising stone substrates.

    In this paper, we discuss the convenience of performing external PIXE and PIGE measurements by scanning relatively large areas (some mm2) with a beam size of the order of hundred microns, rather than performing "spot" compositional analysis. Examples of test runs on samples of archaeometric interest are presented: scanning-mode measurements of ancient inks, Roman glass and metal point drawings clearly demonstrate that using this procedure to perform IBA may become fundamental to avoid deceptive information and to obtain more reliable quantitative results.

  10. A system for Real time monitoring of buildings with cultural heritage importance using wireless sensor networks

    2009-04-01

    Simultaneously real time monitoring of buildings usually requires several different sensors. Even if the number of monitoring items is small the cost of monitoring devices plus the telemetry needed could increased in excessive values. For this reason the use of autonomous sensors is indicated. These devices are self contained embedded computers capable of hosting several sensors and communication boards and providing local computing processing. The acquisition of high resolution physical quantities using low power wireless sensor nodes consist a Wireless Sensor Network (WSN). By using these systems it is easy to collect different data from different clusters of sensors using low cost sensor nodes. The main concern for these approaches is the optimization of data acquisition regarding the management of energy capacity and available radio bandwidth. In this study we propose an optimized management scheme for monitoring historical buildings at the city of Chania using sensor nodes connected to high resolution uniaxial and triaxial embedded accelerometers. A number of sensor nodes are placed in every building. Since an event is not a linear process regarding its time occurrence and the produced results in each sensor node (due to sensor temporary malfunction or existence of noise) we followed a non linear approach. The proposed management scheme focus on the optimum self configuration of the network in a hybrid star topology. It is based on public available TinyOS and produces hierarchical rules in order to have at least one central node (the one that sends all the data to the remote data centre). Example policies that demonstrated is thresholding, noise removal, triggering and event correlation which are implemented using wavelet transform techniques.

    In this paper we report some tests regarding the feasibility of nanodiamond to act as a cleaning/consolidation agent of papers and parchments. We carried out a series of treatments aiming to develop innovative approaches for de-acidification, cleaning and consolidation. Dispersions of nanodiamond have been used as de-acidification agents of ancient papers showing the ability to sensibly reduce the acidity of the paper without using any alkaline base. Similar dispersions have been used for cleaning processes and nanodiamond demonstrated an outstanding capability to clean ancient papers and parchments avoiding the use of any solvent and surfactant. Moreover interesting results were obtained by using nanodiamond as consolidation agent. In particular, artificial aging by UV exposition was appreciably contrasted when samples were preliminarily submitted to a treatment by nanodiamond. This outcome was demonstrated in papers and parchments by Raman spectroscopy analyses that evidenced the property of nanodiamond to be an excellent UV-scavenger.

  12. Multiphoton microscopy: an efficient tool for in-situ study of cultural heritage artifacts

    2013-05-01

    We present multimodal nonlinear optical imaging of historical artifacts by combining Two-Photon Excited Fluorescence (2PEF) and Second Harmonic Generation (SHG) microscopies. Three-dimensional (3D) non-contact laser-scanning imaging with micrometer resolution is performed without any preparation of the objects under study. 2PEF signals are emitted by a wide range of fluorophores such as pigments and binder, which can be discriminated thanks to their different emission spectral bands by using suitable spectral filters in the detection channel. SHG signals are specific for dense non-centrosymmetric organizations such as the crystalline cellulose within the wood cell walls. We also show that plaster particles exhibit SHG signals. These particles are bassanite crystals with a non-centrosymmetric crystalline structure, while the other types of calcium sulphates exhibit a centrosymmetric crystalline structure with no SHG signal. In our study, we first characterize model single-layered samples: wood, gelatin-based films containing plaster or cochineal lake and sandarac film containing cochineal lake. We then study multilayered coating systems on wood and show that multimodal nonlinear microscopy successfully reveals the 3D distribution of all components within the stratified sample. We also show that the fine structure of the wood can be assessed, even through a thick multilayered varnish coating. Finally, in situ multimodal nonlinear imaging is demonstrated in a historical violin. SHG/2PEF imaging thus appears as an efficient non-destructive and contactless 3D imaging technique for in situ investigation of historical coatings and more generally for wood characterization and coating analysis at micrometer scale.

  13. The burn disease: a disease of great value in the cultural heritage of plastic surgery.

    2014-06-30

    In 1961 I began my career as a plastic surgeon at the Department of Plastic Surgery of the Civic Hospital of Padua. In those years, the department was headed by its founder, Prof. G. Dogo, who had just gained his independence to work within the discipline of surgery. Its key feature consisted, at its core, in an entirely new section for those times: the Burn Centre, later known as the "Intensive Care Unit for Acute Burn Victims." At that time, Prof. Masellis, the founder of the Mediterranean Burn Club, was also working among us. The department was still dealing with the disastrous traumatic pathologies that the Italian population had from the Second World War. The beds were still largely occupied by patients suffering from war injuries caused by bomb explosions and fires. These were the reason for the creation of the Burn Centre and subsequently for the promotion of the establishment of a department of plastic surgery. I therefore had the opportunity to see a multitude of different clinical cases and to experiment with the various operation techniques known to plastic surgeons at the time. But it was not only the surgical aspect that fascinated me; I was fascinated by the burn as a disease - the extraordinary problems of their pathophysiology and the logic of treating them, generally and locally - no longer as had been suggested by vague suppositions, but by suggestive hypotheses based on clinical and experimental observations. Over the years, the skills involved in plastic surgery have expanded: its numerous therapeutic procedures have been applied to the treatment of many other diseases. But the burn-as-disease was always at the top of my cultural interests. It always had something to teach me, whether clinically, scientifically or ethically. Yes, even ethically, because the burn patient, like few others who are ill, truly challenges his physician's ethical core and moral strength.

    Protection of surfaces directly exposed to the detrimental action of degradative agents (i.e. oxygen, air pollutants and bacteria) is one of the most important challenges in the field of conservation of works of art. Metallic objects are subjected to specific surface corrosion phenomena that, over the years, make mandatory the research of innovative materials that should avoid the direct contact between the metal surface and the weathering agents. In this paper, the set-up, characterisation and application of a new reversible material for preserving metal artefacts are reported. Micro-layers constituted of low-adhesive polystyrene (PS) films obtained from recycling waste packaging materials made of expanded PS were studied. The morphology and thickness of PS films were characterised by optical, atomic force and scanning electron microscopy (SEM). A further check on thickness was carried out by means of visible spectrophotometry doping the films with a hydrophobic dye. Thermal properties of the PS micro-layers were studied by means of differential scanning calorimetry coupled with optical microscopy. Permeability of the PS films to water vapour was also determined. The potential of the low-adhesive PS films, that enabled an easy removal in case of film deterioration, for preventing metal oxidation was investigated on brass specimens by simulating standard artificial corrosion programmes. Morphological and chemical (coupling the energy-dispersive X-rays spectrometry to SEM measurements) analyses carried out on these metal samples showed promising results in terms of surface protection against corrosion.

    Fluorescence LIDAR imaging has been already proposed in several studies as a valuable technique for the remote diagnostics and documentation of the monumental surfaces, with main applications referring to the detection and classification of biodeteriogens, the characterization of lithotypes, the detection and characterization protective coatings and also of some types of pigments. However, the conservation and documentation of the cultural heritage is an application field where a highly multi-disciplinary, integrated approach is typically required. In this respect, the fluorescence LIDAR technique can be particularly useful to provide an overall assessment of the whole investigated surface, which can be profitably used to identify those specific areas in which further analytical measurements or sampling for laboratory analysis are needed. This paper presents some representative examples of the research carried out in the frame of the PRIMARTE project, with particular reference to the LIDAR data and their significance in conjunction with the other applied techniques. One of the major objectives of the project, actually, was the development of an integrated methodology for the combined use of data by using diverse techniques: from fluorescence LIDAR remote sensing to UV fluorescence and IR imaging, from IR thermography, georadar, 3D electric tomography to microwave reflectometry, from analytical techniques (FORS, FT-IR, GC-MS) to high resolution photo-documentation and historical archive studies. This method was applied to a 'pilot site', a chapel dating back to the fourteenth century, situated at 'Le Campora' site in the vicinity of Florence. All data have been integrated in a multi-medial tool for archiving, management, exploitation and dissemination purposes.

    The era of the International Space Station with its longer duration missions will pose unique challenges to microgravity life sciences research. The Space Station Biological Research Project (SSBRP) is responsible for addressing these challenges and defining the science requirements necessary to conduct life science research on-board the International Space Station. Space Station will support a wide range of cell and tissue culture experiments for durations of 1 to 30 days. Space Shuttle flights to bring experimental samples back to Earth for analyses will only occur every 90 days. Therefore, samples may have to be retained for periods up to 60 days. This presents a new challenge in fresh specimen sample storage for cell biology. Fresh specimen samples are defined as samples that are preserved by means other than fixation and cryopreservation. The challenge of long-term storage of fresh specimen samples includes the need to suspend or inhibit proliferation and metabolism pending return to Earth-based laboratories. With this challenge being unique to space research, there have not been any ground based studies performed to address this issue. It was decided hy SSBRP that experiment support studies to address the following issues were needed: Fixative Solution Management; Media Storage Conditions; Fresh Specimen Sample Storage of Mammalian Cell/Tissue Cultures; Fresh Specimen Sample Storage of Plant Cell/Tissue Cultures; Fresh Specimen Sample Storage of Aquatic Cell/Tissue Cultures; and Fresh Specimen Sample Storage of Microbial Cell/Tissue Cultures. The objective of these studies was to derive a set of conditions and recommendations that can be used in a long duration microgravity environment such as Space Station that will permit extended storage of cell and tissue culture specimens in a state consistent with zero or minimal growth, while at the same time maintaining their stability and viability.

    We propose a method for the precise 3D see-through imaging, or transparent visualization, of the large-scale and complex point clouds acquired via the laser scanning of 3D cultural heritage objects. Our method is based on a stochastic algorithm and directly uses the 3D points, which are acquired using a laser scanner, as the rendering primitives. This method achieves the correct depth feel without requiring depth sorting of the rendering primitives along the line of sight. Eliminating this need allows us to avoid long computation times when creating natural and precise 3D see-through views of laser-scanned cultural heritage objects. The opacity of each laser-scanned object is also flexibly controllable. For a laser-scanned point cloud consisting of more than 107 or 108 3D points, the pre-processing requires only a few minutes, and the rendering can be executed at interactive frame rates. Our method enables the creation of cumulative 3D see-through images of time-series laser-scanned data. It also offers the possibility of fused visualization for observing a laser-scanned object behind a transparent high-quality photographic image placed in the 3D scene. We demonstrate the effectiveness of our method by applying it to festival floats of high cultural value. These festival floats have complex outer and inner 3D structures and are suitable for see-through imaging.

    A total of 757 milk samples were taken from 57 farms throughout Wales as part of a mastitis investigation. Problem cows were selected using the most recent milk recording or, if these data were unavailable, the whole herd was assessed using the California mastitis test (CMT) and scored on a scale of 0 to 3. The affected quarter was identified using CMT. The results of the bacteriology were grouped into negative and positive culture. All contaminated samples were excluded. The CMT recording at the time of sampling, the infection status of the cow (new, first, chronic or repeat) as defined by national milk records and the number of quarters infected at the time of sampling were identified for negative and positive samples. Selecting quarters with a higher CMT score increased the likelihood of positive culture. Culturing from a sample with a CMT score of 3 was over three times more likely to yield a positive culture than a score of 1 (odds ratio [OR] 3.74, 95 per cent confidence interval [CI] 1.41 to 9.97) and 1.7 times more likely to yield a positive culture than a score of 2 (OR 1.70, 95 per cent CI 1.16 to 2.50). Culturing from a score of 2 was not statistically different from a score of 1 in terms of the likelihood that a positive culture would be identified (OR 2.20, 95 per cent CI 0.83 to 5.93). There was no statistically significant difference in the proportion of negative samples when comparing chronic, repeat, new and first infections or number of quarters infected. PMID:20228365

    The development of close-range photogrammetry has produced a lot of new possibility to study cultural heritage. 3D data acquired with conventional and low cost cameras can be used to document, investigate the full appearance, materials and conservation status, to help the restoration process and identify intervention priorities. At the same time, with 3D survey a lot of three-dimensional data are collected and analyzed by researchers, but there are a very few possibility of 3D output. The augmented reality is one of this possible output with a very low cost technology but a very interesting result. Using simple mobile technology (for iPad and Android Tablets) and shareware software (in the case presented "Augment") it is possible to share and visualize a large number of 3D models with your own device. The case study presented is a part of an architecture graduate thesis, made in Rome at Department of Architecture of Roma Tre University. We have developed a photogrammetric survey to study the Aurelian Wall at Castra Praetoria in Rome. The surveys of 8000 square meters of surface have allowed to identify stratigraphy and construction phases of a complex portion of Aurelian Wall, specially about the Northern door of Castra. During this study, the data coming out of 3D survey (photogrammetric and topographic), are stored and used to create a reverse 3D model, or virtual reconstruction, of the Northern door of Castra. This virtual reconstruction shows the door in the Tiberian period, nowadays it's totally hidden by a curtain wall but, little and significative architectural details allow to know its original feature. The 3D model of the ancient walls has been mapped with the exact type of bricks and mortar, oriented and scaled according to the existing one to use augmented reality. Finally, two kind of application have been developed, one on site, were you can see superimposed the virtual reconstruction on the existing walls using the image recognition. On the other hand

  1. Magnetic Gradient Horizontal Operator (MHGO) useful for detecting objects buried at shallow depth: cultural heritage (Villa degli Antonini, Rota Rio)

    Several factors were taken into consideration in order to appropriately tailor the geophysical explorations at the cultural heritage. Given the fact that each site has been neglected for a long time and in recent times used as an illegal dumping area, we thoroughly evaluated for this investigation the advantages and limitations of each specific technique, and the general conditions and history of the site. We took into account the extension of the areas to be investigated and the need for rapid data acquisition and processing. Furthermore, the survey required instrumentation with sensitivity to small background contrasts and as little as possible affected by background noise sources. In order to ascertain the existence and location of underground buried walls, a magnetic gradiometer survey (MAG) was planned. The map of the magnetic anomalies is not computed to reduction at the pole (RTP), but with a magnetic horizontal gradient operator (MHGO). The magnetic horizontal gradient operator (MHGO) generates from a grid of vertical gradient a grid of steepest slopes (i.e. the magnitude of the gradient) at any point on the surface. The MHGO is reported as a number (rise over run) rather than degrees, and the direction is opposite to that of the slope. The MHGO is zero for a horizontal surface, and approaches infinity as the slope approaches the vertical. The gradient data are especially useful for detecting objects buried at shallow depth. The map reveals some details of the anomalies of the geomagnetic field. Magnetic anomalies due to walls are more evident than in the total intensity map, whereas anomalies due to concentrations of debris are very weak. In this work we describe the results of an investigation obtained with magnetometry investigation for two archaeological sites: "Villa degli Antonini" (Genzano, Rome) and Rota Ria (Mugnano in Teverina, Viterbo). Since the main goal of the investigation was to understand the nature of magnetic anomalies with cost

    In times of economic hardship, the support given by specialized civil society organisations to public institutions in the protection of cultural heritage has often proved very useful, and there is evidence that their contribution is essential in times of conflicts and natural disasters, if well-designed plans and measures are organized efficiently, thoroughly tested and properly implemented. The 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict (HC), its two Protocols and other international juridical instruments address these situations since decades, however, they remained widely not-applied in absence of proper regulatory instruments. In 2004, the Second Protocol of the Hague Convention (1999HP) entered into force and the Committee of the State Parties was formed. It became clear that a new trend started when, in 2009, draft Guidelines for the implementation of the 1999HP were issued. Meanwhile, WATCH, in partnership with the Council of the United Municipalitities of Jbail (Lebanon) and the Head of the Municipality of Mtskheta (Georgia) prepared a project proposal aimed to set a precedent in the governance of urban sites that are registered in the World Heritage List which are at risk of armed conflict. The project War Free World Heritage Listed Cities http://www.warfreeheritage.net/ was co-financed in 2010 with a grant within the framework of the EC CIUDAD programme and it is currently at an advanced level of implementation. This presentation will focus on achievements and contingencies faced during implementation as well as lessons learned that could be surely useful for pers pective applicants.

    Cardinal Cisneros launched in 1499 a major universitary project, that was located in Alcala de Henares (Madrid, Spain). It bestowed recently the recognition of the Council of Europe as a World Heritage Site in 1998 by UNESCO. Cisneros created the new university in the vicinity of the Roman town of Complutum. This site had two qualities which were particularly important: it was placed at a safe distance from the power of the Crown at Toledo, and it was well connected with other main Spanish cities, through the Roman road or calzada that crossed the Iberian peninsula from South to North going along some important settlements as Mérida, Toledo, Zaragoza, and Barcelona. Thus the old town of Alcala de Henares still keeps the remains of the Visigothic, Roman, Muslim and Hebrew cultures. Since the end of the fifteenth century the built Renaissance complex has gone through three clear stages, where lots of relevant architects developed their work. Among them, Pedro Gumiel and Rodrigo Gil de Hontañón can be cited for their first drawings, but other anonymous architects have also contributed to build such an interesting project. In a second stage some repairs were needed on the former structures, in order to adapt them to their new functions due to deterioration or even to changes in ownership or uses (as happened to the Colegio Mayor de San Ildefonso). Finally, at the latest stage at the end of the 20th and the early 21st centuries a new regeneration project took place in order to introduce the modern technologies and energy-efficient standards the old universitary buildings. An interesting example of this modern practices on dynamic conservation of the historical heritage is the new Learning and Research Center (LRC) on the ruins of San Diego headquarter built in 1859 on the site of the Franciscan convent of Santa Maria de Jesus, founded in 1445 by Archbishop Alonso Carrillo (which in turn it replaced an earlier one). The aims of the new LRC are to, preserve and

    Samples of air removed from the stratosphere, at an altitude of 41 km, were previously found to contain viable, but non-cultureable bacteria (cocci and rods). Here, we describe experiments aimed at growing these, together with any other organisms, present in these samples. Two bacteria (Bacillus simplex and Staphylococcus pasteuri) and a single fungus, Engyodontium album (Limber) de Hoog were isolated from the samples. Although the possibility of contamination can never be ruled out when space-derived samples are studied on earth, we are confident that the organisms originated from the stratosphere. Possible mechanisms by which these organisms could have attained such a height are discussed. PMID:12583913

    Besides their suitability for multi-temporal and spatial deformation analysis, the Synthetic Aperture Radar (SAR) image archives acquired by space-borne radar sensors can be exploited to support archaeological investigations over huge sites, even those partially or totally buried and still to be excavated. Amplitude information is one of the main properties of SAR data from which it is possible to retrieve evidences of buried structures, using feature extraction and texture analysis. Multi-temporality allows the reconstruction of past and recent evolution of both landscape and built-up environment, with the possibility to detect natural and/or anthropogenic changes, including human-induced damages to the conservation of cultural heritage. We present the methodology and first results of the experiments currently undertaken using SAR data in the Nasca region (Southern Peru), where two important civilizations such as Paracas and Nasca developed and flourished from 4th century BC to the 6th century AD. The study areas include a wide spectrum of archaeological and environmental elements to be preserved, among which: the archaeological site of Cahuachi and its surroundings, considered the largest adobe Ceremonial Centre in the World; the Nasca lines and geoglyphs in the areas of Palpa, Atarco and Nasca; the ancient networks of aqueducts and drainage galleries in the Puquios area, built by Nasca in the 1st-6th centuries AD. Archaeological prospection and multi-purpose remote sensing activities are currently carried out in the framework of the Italian mission of heritage Conservation and Archaeogeophysics (ITACA), with the direct involvement of researchers from the Institute for Archaeological and Monumental Heritage and the Institute of Methodologies for Environmental Analysis, Italian National Research Council. In this context, C- and L-band SAR images covering the Nasca region since 2001 were identified for the purposes of this research and, in particular, the following

    The Government Accountability Office’s report, Climate Change Adaption, examines federal, state, local, and international mitigation actions for climate change and sea-level rise. The report specifically addresses the dearth of Site-Specific Information relating to the effects of climate change on a localized scale and the challenges this poses for the development of adaption strategies. We are developing a model that will begin to regionalize climate change projections for the purpose of projecting the effects of climate change on coastal cultural heritage. As global sea level increases, so too will the number of historically significant landscapes that are threatened due to sea-level rise. Because of this, historical preservationists will require a greater availability of pertinent information in order to contend with the threats posed by climate change and rising sea levels. These threats will have a far greater impact on Low Elevation Coastal Zones (LECZ) areas. The US ranks third for land mass classified as LECZ and has an estimated population of 22 million people living within these regions. Many of these areas have had high population densities due to the concentration of marine fishery resources, ease of transportation, and agricultural associations with river deltas. These areas have acted as catalysts for the evolution of various societies and cultures, and contain a concentrated stratification of cultural heritage deposits. The development of models for the assessment of spatial/temporal impacts of climate change on coastal cultural heritage will play a significant role in defining long-term preservation needs on a regional scale. We are coordinating ground water seepage models, tidal estuary models, and the regionalized Global Climate Models with localized geophysical assessments and GIS data sets. Through the digitization and rectification of various contemporary and historical maps we have developed a GIS data set that reflects the evolution of the

    We present the radar-interpretation of a 4year-long stack of ENVISAT ASAR imagery, integrated and cross-validated with optical-Very High Resolution (VHR) data from QuickBird2, GeoEye and WorldView-1/2, and carried out over the cultural and natural heritage of the Nasca region in Southern Peru. This research is performed thanks to the provision of free-access archive SAR data from the European Space Agency (ESA) through the Cat-1 project 11073, and is supporting the activities of the Italian mission of heritage Conservation and Archaeogeophysics (ITACA), which directly involve researchers from the Institute for Archaeological and Monumental Heritage (IBAM) and the Institute of Methodologies for Environmental Analysis (IMAA), National Research Council (CNR) of Italy. The whole ENVISAT ASAR imagery archive, consisting of 8 ASAR IS2 scenes acquired in descending mode between 04/02/2003 and 15/11/2005 and 5 images in ascending mode between 24/07/2005 and 11/11/2007, was processed by exploiting and analyzing SAR amplitude information and change detection to reconstruct the temporal evolution of radar signatures and related backscattering coefficient (σ0) of the targets on the ground in the monitoring period 2003-2007. The selection of a SAR amplitude-based change detection method was made to explore its actual potentials for archaeological prospection and monitoring purposes, complementarily to approaches of interferometric coherence used by other scholars over the same region of investigation. The novel contribution to heritage studies over Nasca includes remote sensing insights into the renowned UNESCO-WHL Nasca geoglyphs and archaeological mounds of the adobe Ceremonial Centre of Cahuachi, as well as the ancient puquios within the Rio Grande drainage basin. The latter are prehispanic underground aqueducts, and nowadays represent not only important cultural features to preserve, but also a potential driver to revitalize waterways and oases in such a dry region

    3D imaging sensors for the acquisition of three dimensional (3D) shapes have created, in recent years, a considerable degree of interest for a number of applications. The miniaturization and integration of the optical and electronic components used to build them have played a crucial role in the achievement of compactness, robustness and flexibility of the sensors. Today, several 3D sensors are available on the market, even in combination with other sensors in a “sensor fusion” approach. An importance equal to that of physical miniaturization has the portability of the measurements, via suitable interfaces, into software environments designed for their elaboration, e.g., CAD-CAM systems, virtual renders, and rapid prototyping tools. In this paper, following an overview of the state-of-art of 3D imaging sensors, a number of significant examples of their use are presented, with particular reference to industry, heritage, medicine, and criminal investigation applications.

    The understanding and assessment of environmental impact on heritage assets is of the highest importance for heritage preservation through well-organized maintenance based on proper decision-making. The effort towards development of protocol that would enable comparison of data on heritage assets in Europe and Mediterranean countries was done through EU Project European Cultural Heritage Identity Card. The special attention was paid to classification of environmental and man-induced risks to heritage. In the present paper the idea of EU CHIC is presented. Environmental risks are discussed in context of their influence on structure of heritage buildings that are exposed to sudden environmental impacts.

    We evaluated two protocols for isolation of Helicobacter pylori in stool from biopsied and nonbiopsied children. Twenty-three child patients whose presumptive positivity or negativity was diagnosed by endoscopy and a rapid urease test at site were used to compare biopsy-based tests with stool-based tests (H. pylori stool antigen test and stool culture). Their gastric activity and bacterial density were graded by the updated Sydney system. Biopsy and stool specimens were cultured on Campy-blood and Belo horizonte agar plates after enrichment in selective Campy-Thio medium. To compare two stool culture protocols, stools from 20 nonbiopsied children were tested by the HpSA test and cultured either as above or after treatment with cholestyramine. Grown colonies were screened by Gram staining, slide agglutination using anti-H. pylori monoclonal IgG; positive isolates were tested by biochemical tests and polymerase chain reaction for H. pylori-specific ureA gene. Coccoid H. pylori was isolated in stool samples from the biopsied patients whose bacterial density was two to four in histology. Their oxidase was slightly positive but became positive after two subcultures, while additional biochemical tests confirmed the isolation of H. pylori. Similar coccoid but oxidase positive H. pylori was isolated from three nonbiopsied children with the protocol of cholestyramine treatment only. The density of bacteria in the stomach may influence the recovery of H. pylori from stool; inactivation of bile with cholestyramine improves the yield in culture and favors isolation of an enhanced metabolic form of bacteria.

    This article presents the results of an initial efficacy trial of a parenting intervention, Familias: Preparando la Nueva Generación (FPNG), used to strengthen parenting practices, specifically, open family communication. Using community-based participatory research, including stakeholder involvement, the FPNG curriculum was developed, evaluated for feasibility, and revised to complement the classroom-based keepin' itREAL youth substance-use prevention program. FPNG focuses on family influences that characterize Mexican-heritage youth and families, including the impact of acculturation. The 9 middle schools were block-randomized into 3 groups: parents and youth (PY), youth only (Y), and control (C) conditions. Parents of 7th grade youth (N = 393, 82.8% mothers) completed self-report surveys at baseline and immediately following the intervention. Structural equation model analyses confirmed that PY parents reported significantly greater levels of open family communication at the follow-up compared with Y parents; C parents were not significantly different from Y parents at follow-up. The inclusion of parents in adolescent-focused preventive interventions might increase the effect size of an original and efficacious youth prevention intervention. PMID:23805361

    2014-06-01

    Medieval town centres and landscapes along the Way of St. James are being affected by renewable energy sources at the architectural, urban and territorial scales. The impact is not only visual, but thermal, accoustic and electromagnetic. Visual impact of solar photovoltaic power plants - which are placed over traditional crops close to the urban borders -, and also wind farms located at the hilltops, are sometimes remarkable. Solar photovoltaic modules are integrated into ancient roofs, and small scale wind turbines are taking up the ancient urban spaces. Among other effects on animal life and vegetation, the rise in temperature, radioelectric interferences, as well as changes in the traditional land uses are noticeable, and a deep analysis is needed. Our main target is to define an integrated methodology which considers all these effects. As a part of our project premises, we work with Open Source programs. We obtained a digital terrain model - 25 m spatial resolution -, and from Corine Land Cover images we got different raster files according to our research targets. Databases where implemented from both remote sensing and measures obtained directly in the field work. We applied GIS based multicriteria decision analysis and weighted linear combination, and then we adapted GRASS tools for a better usability. Our case studies are particularly interesting due to their situation along the Spanish Way of St. James, which is an itinerary named one of UNESCO's World Heritage Sites.

  18. The Material Culture of Nineteenth-Century Astrometry, its Circulation and Heritage at the Astronomical Observatory of Lisbon

    NASA Astrophysics Data System (ADS)

    Raposo, Pedro

    The Astronomical Observatory of Lisbon was founded in 1857 in the sequence of a controversy on stellar parallax measurements involving astronomers from the Observatory of Paris and the Observatory of Pulkovo. The development of this discussion led the contenders to recognize Lisbon as a suitable place to carry out this kind of measurements and to foster the field of stellar astronomy. Some local actors strived to keep up with this wave of international interest and establish a first-rank astronomical institution in the Portuguese capital. In order to fulfil this goal, correspondence was intensively exchanged with leading foreign astronomers and instrument makers. Besides, a Portuguese Navy officer bound to become the first director of the new institution was commissioned to visit several observatories and instrument workshops abroad, and to spend a few years in Pulkovo as a trainee astronomer. Although founded with generous financial support from the Portuguese crown and lavishly equipped and constructed, the Observatory of Lisbon was later affected by limiting budgets and a shortage of qualified personnel. Nevertheless, local efforts to improve instruments as well as observation and calculation techniques enabled its astronomers to yield important contributions to positional astronomy, especially towards the end of the nineteenth century and the beginnings of the twentieth century. The original instruments and spaces of the Observatory of Lisbon, strongly modelled on those of Pulkovo, are very well preserved, constituting an outstanding extant example of a mid-nineteenth century advanced observatory. The history they embody testifies the connectedness of the astronomical heritage worldwide.

    Chemistry is the central science, as it touches every aspect of the society we live in and it is intertwined with many aspects of our culture; in particular, the strong link between Chemistry and Archaeology and Art History is being explored, offering a penetrating insight into an area of growing interest from an educational point of view. A series of vital and vibrant examples (i.e., ancient bronzes composition, colour changes due to natural pigment decomposition, marble degradation) has been proposed, on one hand, to improve student understanding of the relationship between cultural and scientific issues arising from the examination, the conservation, and the maintenance of cultural Heritage, on the other, to illustrate the role of the underlying Chemistry. In some case studies, a survey of the most relevant atmospheric factors, which are involved in the deterioration mechanisms, has also been presented to the students. First-hand laboratory experiences have been providing an invaluable means of discovering the full and varied world of Chemistry. Furthermore, the promotion of an interdisciplinary investigation of a famous painting or fresco, involving the study of its nature and significance, the definition of its historical context, any related literature, the chemical knowledge of the materials used, may be an excellent occasion to experiment the Content and Language Integrated Learning (CLIL). The aim of this approach is to convey the important message that everyone has the responsibility to care for and preserve Heritage for the benefit of present and future generations.

    This work presents a case study developed in San Juan Bautista church in Talamanca de Jarama (12th -16th Century), which have been selected as an example of a historical church with a complex construction with subsequent combination of architectural styles and building techniques and materials. These materials have a differential behavior under the influence of external climatic conditions and constructive facts. Many decay processes related to humidity are affecting the building's walls and also have influence in the environmental dynamics inside the building. A methodology for monitoring moisture distribution on stone and masonry walls and floors was performed with different non-invasive techniques as thermal imaging, wireless sensor networks (WSN), portable moisture meter, electrical resistivity tomography (ERT) and ground-penetrating radar (GPR), in order to the evaluate the effectiveness of these techniques for the knowledge of moisture distribution inside the walls and the humidity origin. North and south oriented sections, both on walls and floors, were evaluated and also a general inspection in the church was carried out with different non-invasive techniques. This methodology implies different monitoring stages for a complete knowledge of the implication of outdoors and indoors conditions on the moisture distribution. Each technique is evaluated according to its effectiveness in the detection of decay processes and maintenance costs.

    Research laboratories, raw materials and media suppliers as well as the biopharmaceutical industry face recurrent contamination with Mollicutes. Culture-based detection methods are very slow (28 days) and could ideally be replaced by nucleic acid testing (NAT) for rapid result. These methods are nonetheless hampered by their companion sample preparation methods. They are limited by the volume tested (0.1 to 5 mL), the protein/nucleic acid content they can accommodate and are generally performed in an open environment. The processing of low volumes of complex matrices is associated to several issues such as poor representativeness, low sensitivity, inhibition and false positives. The novel sample preparation method described in this study has been developed to overcome these limitations and to process 20-mL samples containing high loads of eukaryotic cells. A dual-membrane device is coupled to magnetic bead purification. In one single and closed device, eukaryotic cells and microorganisms are separated, contaminants are concentrated, lysed and corresponding nucleic acids are collected. This novel sample preparation method has been tested with 9 different Mollicutes. The ability to detect the contaminants down to 0.6 CFU/mL by real-time PCR among hundreds of millions of CHO-S cells (Chinese hamster ovary cells, adapted to serum-free suspension culture), without biological pre-enrichment, has been demonstrated. The novel device has been compared to manual silica spin columns, which remain the gold standard in most laboratories. These columns failed to yield the same limit of detection and reproducible results without separating mammalian cells from contaminants. Co-culture experiments have shown that the novel method allows detection of Mollicutes grown for days in presence of mammalian cells, despite the fact that these microorganisms can adhere to eukaryotic cells or invade them. The co-culture data also suggest that the novel sample preparation device might improve

    In this work we develop a multiply interconnected system which involves objects, agents and interactions between them from the use of ICT applied to open repositories, users communities and web services. Our approach is applied to Architectural Cultural Heritage Environments (ACHE). It includes components relative to digital accessibility (to augmented ACHE repositories), contents management (ontologies for the semantic web), semiautomatic recognition (to ease the reuse of materials) and serious videogames (for interaction in urban environments). Their combination provides a support for local real/remote virtual tourism (including some tools for low-level RT display of rendering in portable devices), mobile-based smart interactions (with a special regard to monitored environments) and CH related games (as extended web services). Main contributions to AR models on usual GIS applied to architectural environments, concern to an interactive support performed directly on digital files which allows to access to CH contents which are referred to GIS of urban districts (involving facades, historical or preindustrial buildings) and/or CH repositories in a ludic and transversal way to acquire cognitive, medial and social abilities in collaborative environments.

    To precisely visualize the Royal City of Angkor Thom, Cambodia, we used a new method in field of cultural heritage study. Read Relief Image Map (RRIM, Chiba et al., 2008) is a powerful method which has been used for geomorphological studies. In this study, using the LiDAR data conducted at the Angkor Archaeological Park in Cambodia in April 2012 (Evans et al., 2013), we visualized the Royal City of Angkor Thom and its vicinity (Shimoda et al., 2016). The RRIM provided a new visualization method of localizing, minute topographical changes in regions with large undulations over a wide area. It has proved to be effective in mapping, on a single wide-area map, the numerous buried remains that exist as comparable height differences or minute undulations measuring less than 1 meter in height, and provides a unique aerial view of their widespread distribution. Based on the RRIM map, past archaeological studies were referenced to reconstruct the layout of the water channel network system. Past studies revealed that a large number of ponds had been dug inside Angkor Thom. The RRIM expanded the investigation and revealed the existence of many ponds outside the royal capital indicating that a residential community had flourished outside the moat surrounded capital city.

    The filamentous fungus Stachybotrys chartarum is known for its toxic metabolites and has been associated with serious health problems, including mycotoxicosis, among occupants of contaminated buildings. Here, we present results from a case study, where an ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed for known and tentatively identified compounds characterized via UHPLC-quadruple time-of-flight (QTOF) screening of fungal culture extracts, wall scrapings and reference standards. The UHPLC-MS/MS method was able to identify 12 Stachybotrys metabolites, of which four could be quantified based on authentic standards and a further six estimated based on similarity to authentic standards. Samples collected from walls contaminated by S. chartarum in a water-damaged building showed that the two known chemotypes, S and A, coexisted. More importantly, a link between mycotoxin concentrations found on contaminated surfaces and in settled dust was made. One dust sample, collected from a water-damaged room, contained 10 pg/cm(2) macrocyclic trichothecenes (roridin E). For the first time, more than one spirocyclic drimane was detected in dust. Spirocyclic drimanes were detected in all 11 analysed dust samples and in total amounted to 600 pg/cm(2) in the water-damaged room and 340 pg/cm(2) in rooms adjacent to the water-damaged area. Their wide distribution in detectable amounts in dust suggested they could be good candidates for exposure biomarkers.

    A combination of 3D micro X-ray fluorescence spectroscopy (3D micro-XRF) and micro-XRF was utilized for the investigation of a small collection of highly heterogeneous, partly degraded Dead Sea Scroll parchment samples from known excavation sites. The quantitative combination of the two techniques proves to be suitable for the identification of reliable marker elements which may be used for classification and provenance studies. With 3D micro-XRF, the three-dimensional nature, i.e. the depth-resolved elemental composition as well as density variations, of the samples was investigated and bromine could be identified as a suitable marker element. It is shown through a comparison of quantitative and semiquantitative values for the bromine content derived using both techniques that, for elements which are homogeneously distributed in the sample matrix, quantification with micro-XRF using a one-layer model is feasible. Thus, the possibility for routine provenance studies using portable micro-XRF instrumentation on a vast amount of samples, even on site, is obtained through this work. PMID:21711051

    Alkaline earth metal hydroxide nanoparticles dispersions have demonstrated to be efficient for the preservation of cellulose-based artifacts, providing a stable neutral environment and, if in excess, turning into mild alkaline species. New formulations tailored for specific conservation issues have been recently obtained via a solvothermal reaction, starting from bulk metal, and short chain alcohols. Using this synthetic procedure, stable, and high concentrated calcium hydroxide nanoparticles dispersions can be obtained. The characterization of nanoparticles was carried out by dynamic light scattering, transmission electron microscopy and X-ray powder diffraction and showed that the dispersed systems are particularly suitable for the application on porous substrates. In a direct application of this technology, acidic paper and canvas samples were artificially aged after deacidification using calcium hydroxide nanoparticles dispersed in short chain alcohols. Cellulose viscosimetric polymerization degree (DPv), cellulose pyrolysis temperature, and samples' pH were evaluated upon the aging and in terms of protective action arising from the applied treatment. In particular, determinations of DPv clearly showed that the degradation of acidic paper and canvas samples proceeds at higher rates with respect to deacidified samples. These evidences were also confirmed by the thermogravimetric analysis of samples, in which the benefits due to the deacidification treatments are measured in terms of pyrolysis temperature of cellulose. These new formulations of nanoparticles dispersions expand the palette of available tools for the conservation of cellulose-based works of art, such as easel paintings, and manuscripts, potentially opening the way for the intervention on parchment and leather, whose preservation is a particularly challenging task.

    Recently a new thematic of research — intentional patinas on antic copper-base objects — lead the AGLAE (Accélérateur Grand Louvre pour l'Analyse Elémentaire) team of the C2RMF (Centre de Recherche et de Restauration des Musées de France) to improve its methods of analyzing thin surface layers both in their elemental composition and in-depth elemental distribution. A new beam extraction set-up containing a particle detector has been developed in order to use a 6 MeV alpha beam both in PIXE and RBS mode and to monitor precisely the ion dose received by the sample. Both RBS and ionization cross sections were assessed in order to make sure that the analysis can be quantitative. This set up allows great progresses in the understanding of both nature and structure of this very particular oxide layer obtained in the antiquity by chemical treatment on copper alloys, containing gold and/or silver and presenting very interesting properties of color and stability. Besides the non destructive properties of the IBA in external beam mode, this method of analyzing allows the study of samples in interaction with its environment. This was used to study the high temperature oxidation of Cu-Sn alloys using a furnace developed in order to heat a sample and analyze it in RBS mode at the same time. This new way of studying the growth of oxide layers permits to understand the oxidation mechanism of this system and to propose an experimental model for the identification of oxide layers due to an exposition to a high temperature, model needed for a long time by curators in charge of the study and the conservation of archaeological bronzes.

A new beam extraction set-up containing a particle detector has been developed in order to use a 6 MeV alpha beam both in PIXE and RBS mode and to monitor precisely the ion dose received by the sample. Both RBS and ionization cross sections were assessed in order to make sure that the analysis can be quantitative. This set up allows great progresses in the understanding of both nature and structure of this very particular oxide layer obtained in the antiquity by chemical treatment on copper alloys, containing gold and/or silver and presenting very interesting properties of color and stability.Besides the non destructive properties of the IBA in external beam mode, this method of analyzing allows the study of samples in interaction with its environment. This was used to study the high temperature oxidation of Cu-Sn alloys using a furnace developed in order to heat a sample and analyze it in RBS mode at the same time. This new way of studying the growth of oxide layers permits to understand the oxidation mechanism of this system and to propose an experimental model for the identification of oxide layers due to an exposition to a high temperature, model needed for a long time by curators in charge of the study and the conservation of archaeological bronzes.

  18. Cultural heritage conservation and communication by digital modeling tools. Case studies: minor architectures of the Thirties in the Turin area

    Between the end of the twenties and the beginning of the World war two Turin, as the most of the Italian cities, was endowed by the fascist regime of many new buildings to guarantee its visibility and to control the territory: the fascist party main houses and the local ones. The style that was adopted for these constructions was inspired by the guide lines of the Modern movement which were spreading by a generation of architects as Le Corbusier, Gropius, Mendelsohn. At the end of the war many buildings were reconverted to several functions that led heavy transformations not respectful of the original worth, other were demolished. Today it's possible to rebuild those lost architectures in their primal format as it was created by their architects on paper (and in their mind). This process can guarantee the three-dimensional perception, the authenticity of the materials and the placement into the Turin urban tissue, using static and dynamic digital representation systems. The "three-dimensional re-drawing" of the projects, thought as an heuristic practice devoted to reveal the original idea of the project, inserts itself in a digital model of the urban and natural context as we can live it today, to simulate the perceptive effects that the building could stir up today. The modeling skills are the basis to product videos able to explore the relationship between the environment and "re-built architectures", describing with the synthetic movie techniques, the main formal and perceptive roots. The model represents a scientific product that can be involved in a virtual archive of cultural goods to preserve the collective memory of the architectural and urban past image of Turin.

    In this work, a study of detection systems in portable X-ray fluorescence (PXRF) spectrometry was performed. An assessment of various detectors and their influence on the measurement of trace elements in different bulk materials, from light to heavy matrices, was done. Four reference materials were analyzed: Orchard Leaves (NBS-1571); Bone Meal (NIST-1486); River Sediment (NBS-1645) and Free-Cutting Brass (NBS-1105). Detection limits were calculated for the elements present in the reference materials, quantitative calculations were performed for three known samples and a comparison was made for each detector. Three case studies were also performed in order to appraise the behavior of the detection systems: A paper document from 1909, a potassium alum/calcite mixture and a Portuguese coin.

  20. Data and interpretation: enhancing conservation of art and cultural heritage through collaboration between scientist, conservator, and art historian

    Conservation practices can be greatly enhanced and influenced by scientific analysis and art historical insights. In the same respect, scientific data can be contextualized and substantiated by findings from visual examination and historical research. Such collaboration can contribute to the field of conservation in multiple ways: by assisting the conservator to investigate treatment options, discover artists' materials and techniques, determine date of manufacture, and investigate conservation treatment materials. Several technical studies conducted by the author and her collaborators employed micro-x-ray fluorescence (μ-XRF), Raman Spectroscopy, Fourier-transform infrared spectrometry (FTIR), and scanning electron microscopy with energy dispersive x-ray spectroscopy (SEM-EDS) and polarized light microscopy (PLM). These techniques were used on the following previously published projects such as a Japanese painting at the Museum of Fine Arts at Boston, Thai manuscripts at the Arthur M. Sackler Museum at Harvard University, and Chinese export paintings on pith at the Winterthur Museum. Although these studies have been published in the past, they are worthy examples to illustrate how collaborations between conservator, scientist, and art historian complement one another. This presentation will also touch upon ethics in sampling of fine art materials and several online databases such as Infrared and Raman User Group (IRUG) and Conservation and Art Materials Encyclopedia Online (CAMEO), which have proven to be very helpful in the field of conservation.

    At the 5.5 MV Tandem VdG accelerator of the Institute of Nuclear Physics of N.C.S.R. "Demokritos", Athens, Greece, an external ion-beam set-up has been recently developed and installed. The aim of this development was to integrate the analytical capabilities of the PIXE, RBS and PIGE ion beam techniques in one experimental set-up, so that to attain a complete elemental and near surface structural characterization of samples in an almost non-destructive way and without any limitation concerning their size or conductive state. A careful 3D mechanical drawing optimized the set-up experimental parameters achieving probe dimensions at the millimeter range (1 mm 2) and fulfilling the special requirements imposed for optimum performance of the aforementioned techniques, including the possibility to use heavier, than protons, ion beams. For the digital pulse processing of the X-ray, γ-ray and charged particle detector signals, novel hardware and software tools were developed based on a custom FPGA configuration. The first applications were focused in the quality control of materials that have been intentionally contaminated with a particular tracer-element ("tagged" materials). The tagged materials which were developed and tested are technologically authentic replicas of ancient attic ceramics with black glazed decoration. Analytical diagnostic studies were carried out for a few representative paintings of contemporary Greek painters in order to identify and document materials/pigments and techniques and eventually to prevent trade of fakes. Finally, ancient glass beads were also examined with respect to the sodium concentration and its in-depth homogeneity.

    I present a very broad overview of what I have learned about personality trait assessment at different levels and offer some views on future directions for research and clinical practice. I review some basic principles of scale development and argue that internal consistency has been overemphasized; more attention to retest reliability is needed. Because protocol validity is crucial for individual assessment and because validity scales have limited utility, I urge combining assessments from multiple informants, and I present some statistical tools for that purpose. As culture-level traits, I discuss ethos, national character stereotypes, and aggregated personality traits, and summarize evidence for the validity of the latter. Our understanding of trait profiles of cultures is limited, but it can guide future exploration. PMID:23924211

    The concept of sustainability has been an integral part of development work since the late 1970s. Sustainability is no longer a buzzword but a reality that must be addressed by cities all over the world. Increasing empirical evidence indicates that city sustainability is not just related to technical issues, such as carbon emissions, energy consumption and waste management, or on the economic aspects of urban regeneration and growth, but also it covers social well-being of different groups living within increasingly cosmopolitan towns and cities. Heritage is seen as a major component of quality of life, features that give a city its unique character and provide the sense of belonging that lies at the core of cultural identity. In other words, heritage by providing important social and psychological benefits enrich human life with meanings and emotions, and raise quality of life as a key component of sustainability. The purpose of this paper, therefore, is to examine the role that built cultural heritage can play within sustainable urban development.

  10. Detection limits of Legionella pneumophila in environmental samples after co-culture with Acanthamoeba polyphaga

    PubMed Central

    2013-01-01

    Background The efficiency of recovery and the detection limit of Legionella after co-culture with Acanthamoeba polyphaga are not known and so far no investigations have been carried out to determine the efficiency of the recovery of Legionella spp. by co-culture and compare it with that of conventional culturing methods. This study aimed to assess the detection limits of co-culture compared to culture for Legionella pneumophila in compost and air samples. Compost and air samples were spiked with known concentrations of L. pneumophila. Direct culturing and co-culture with amoebae were used in parallel to isolate L. pneumophila and recovery standard curves for both methods were produced for each sample. Results The co-culture proved to be more sensitive than the reference method, detecting 102-103 L. pneumophila cells in 1 g of spiked compost or 1 m3 of spiked air, as compared to 105-106 cells in 1 g of spiked compost and 1 m3 of spiked air. Conclusions Co-culture with amoebae is a useful, sensitive and reliable technique to enrich L. pneumophila in environmental samples that contain only low amounts of bacterial cells. PMID:23442526

  12. On the Need for Reliable Seismic Input Assessment for Optimized Design and Retrofit of Seismically Isolated Civil and Industrial Structures, Equipment, and Cultural Heritage

    NASA Astrophysics Data System (ADS)

    Martelli, Alessandro

    2011-01-01

    Based on the experience of recent violent earthquakes, the limits of the methods that are currently used for the definition of seismic hazard are becoming more and more evident to several seismic engineers. Considerable improvement is felt necessary not only for the seismic classification of the territory (for which the probabilistic seismic hazard assessment—PSHA—is generally adopted at present), but also for the evaluation of local amplification. With regard to the first item, among others, a better knowledge of fault extension and near-fault effects is judged essential. The aforesaid improvements are particularly important for the design of seismically isolated structures, which relies on displacement. Thus, such a design requires an accurate definition of the maximum value of displacement corresponding to the isolation period, and a reliable evaluation of the earthquake energy content at the low frequencies that are typical of the isolated structures, for the site and ground of interest. These evaluations shall include possible near-fault effects even in the vertical direction; for the construction of high-risk plants and components and retrofit of some cultural heritage, they shall be performed for earthquakes characterized by very long return periods. The design displacement shall not be underestimated, but neither be excessively overestimated, at least when using rubber bearings in the seismic isolation (SI) system. In fact, by decreasing transverse deformation of such SI systems below a certain value, their horizontal stiffness increases. Thus, should a structure (e.g. a civil defence centre, a masterpiece, etc.) protected in the aforesaid way be designed to withstand an unnecessarily too large earthquake, the behaviour of its SI system will be inadequate (i.e. it will be too stiff) during much more frequent events, which may really strike the structure during its life. Furthermore, since SI can be used only when the room available to the structure

    Melissa officinalis L. (lemon balm) is normally consumed as an infusion and presents therapeutic properties, such as sedative, carminative and antispasmodic, also being included in some pharmaceutical preparations. The phenolic profiles of different samples of lemon balm, prepared as infusions, were evaluated by HPLC-DAD-ESI/MS. The profiles were compared in order to understand the differences between cultivated, in vitro cultured and commercial (bags and granulated) samples. All the samples showed a similar phenolic profile, presenting differences only in the quantities found of each compound. Rosmarinic acid was the most abundant compound, being higher in commercial samples, especially in tea bag sample (55.68mg/g of infusion) and lower in in vitro cultured sample (15.46mg/g). Moreover, dimers, trimers and tetramers of caffeic acid were identified and quantified for the first time in lemon balm. Only one flavonoid, luteolin-3'-O-glucuronide was found in all the samples, ranging from 8.43mg/g in commercial granulate sample to 1.22mg/g in in vitro cultured sample. Overall, cultivated and in vitro cultured samples presented the lowest amounts of phenolic compounds (59.59 and 30.21mg/g, respectively); otherwise, commercial samples showed the highest contents (109.24mg/g for tea bag and 101.03mg/g for granulate sample). The present study shows that infusion of lemon balm can be a source of phenolic compounds, known for their bioactive effects. PMID:23017385

    The core lipids of methanogens comprise C20 and C40 isoprenoid chains, linked through ether bonds to glycerol. Additional structural diversity is encoded into the polar head groups that are attached to the glycerol ether cores. These compounds are potentially very useful as taxonomic markers in microbial mats and other environmental samples while the nature of the hydrocarbon chains provide a means to identify methanogenic inputs to ancient sediments. The structural diversity of methanogen polar lipids is most valuable when it can be directly correlated to 16S rRNA phylogeny. On the other hand, this diversity can also leads to analytical challenges because there is no single approach that works for all structural types. While some intact methanogen lipids have been identified using mass spectrometry and NMR spectroscopy, the most common means of analysing the lipid cores involves cleavage of the ether bonds using HI and subsequent reduction of the alkyl iodides to hydrocarbons with LiAlH4. One class of methanogenic lipids, the 3?-hydroxyarchaeols, escaped detection for some years because strong acid treatments in the analysis protocols destroyed hydroxyl-containing isoprenoid chains. We have been systematically re-examining the lipids of methanogens, using milder procedures involving weak acid hydrolysis of polar head groups, derivatisation to form trimethylsilyl ethers and analysis by GC-MS. As well as archaeol, sn-2- and sn-3-hydroxyarchaeol, we have tentatively identified a dihydroxyarchaeol in several Methanococcus sp. For Methanococcus thermolithotrophicus an analysis of the total lipid extracts using BBr3 as an ether cleavage reagent followed by LiBEt3H, reduction revealed a very complex mixture consisting of phytane, phytenes, biphytane, biphytenes and a suite of related alcohols. The latter compounds were analysed by GC-MS as their trimethylsilyl ethers and found to comprise a mixture tentatively identified as phytan-N-ol and biphytan-N-ol where N= 3 or 7

    A quantitative real-time PCR (qPCR) based on a standard curve was developed for detection and quantitation of ranaviruses. The target gene for the qPCR was viral DNA polymerase (DNApol). All ten ranavirus isolates studied (Epizootic haematopoietic necrosis virus, EHNV; European catfish virus, ECV; European sheatfish virus, ESV; Frog virus 3, FV3; Bohle iridovirus, BIV; Doctor fish virus, DFV; Guppy virus 6, GV6; Pike-perch iridovirus, PPIV; Rana esculenta virus Italy 282/I02, REV282/I02 and Short-finned eel ranavirus, SERV) were detected with the qPCR assay. In addition, two fish cell lines - epithelioma papulosum cyprini (EPC) and bluegill fry (BF-2) - were infected with four of the isolates (EHNV, ECV, FV3 and DFV), and the viral quantity was determined from seven time points during the first three days after infection. The qPCR was also used to determine the viral load in tissue samples from pike (Esox lucius) fry challenged experimentally with EHNV. PMID:21087639

    The aim of this study was to assess the diagnostic value of the BACTEC FX blood culture (BC) system as compared to the agar culture (AC) of cerebrospinal fluid samples (CSF), evaluating the recovery rate and the time to detection of microorganisms in a 3.5-year period. From December 2011 to May 2015, 1326 CSF samples (694 patients) were submitted to both AC and BC. Among the 150 positive samples (96 patients), 165 microorganisms were detected: 81 by both the protocols, 77 by BC alone, and 7 by AC alone, demonstrating a higher detection rate of BC (95.8%) than AC (53.3%). Although BC presents some disadvantages, it is able to improve the yield of clinically significant microorganisms, and it could potentially reduce the reporting time as compared to AC. The results obtained highlighted the necessity of a combined approach for the successful detection of central nervous system microbial infections. PMID:26867963

    An integrated computational approach allowed an unbiased analysis of optical and structural properties of alizarin-based pigments, which can be directly compared with experimental results. Madder lake pigments have been modeled by Mg(II)- and Al(III)-coordinated alizarin taking into account solvation and metal-linkage effects, responsible for colour modifications. Moreover, different environmental conditions have been analyzed for free alizarin, showing in all cases semi-quantitative agreement with experimental spectroscopic data (UV-VIS). Our results point out the ability of in silico approaches to unravel the subtle interplay of stereo-electronic, dynamic, and environmental effects in tuning the physico-chemical properties of pigments relevant for cultural heritage.

To answer these questions, this paper, will use the Old Summer Palace ruins as an example and look at its design of monitoring systems and upcoming monitoring activities of its ruins. It will also consider how the Old Summer Palace makes a preliminary attempt to build a monitoring system for one of China's "Large Ruins" by exploring the aspects of monitoring necessity, identification of monitoring targets, and building of monitoring system of the European-style Palace of the Old Summer Palace.

    At the turn of the century, a series of new heritage concepts have appeared in the area of international cultural heritage protection, such as cultural landscape, cultural route, heritage corridor, heritage canal, which presents the development of people's recognition of cultural heritage. According to The Operational Guidelines for the Implementation of the World Heritage Convention, management planning must be contained in the material used to apply for world heritage. The State Administration of Cultural Heritage designed the mission and work schedule of China's Grand Canal conservation planning in 2008. This research will introduce the working system of China's Grand Canal conservation planning on three levels: city, province and nation. It will also summarize the characteristics of the core technologies in China's Grand Canal conservation planning, including key issues like the identification of the core characteristic of China's Grand Canal, value assessment and determination of the protection scope. Through reviewing, thinking and analyzing the previous accomplishments, the research will offer some advices for the similar world heritage conservation planning after.

    Secreted from adipose tissue, adiponectin is a vital endocrine hormone that acts in glucose metabolism, thereby establishing its crucial role in diabetes, obesity, and other metabolic disease states. Insulin exposure to primary adipocytes cultured in static conditions has been shown to stimulate adiponectin secretion. However, conventional, static methodology for culturing and stimulating adipocytes falls short of truly mimicking physiological environments. Along with decreases in experimental costs and sample volume, and increased temporal resolution, microfluidic platforms permit small-volume flowing cell culture systems, which more accurately represent the constant flow conditions through vasculature in vivo. Here, we have integrated a customized primary tissue culture reservoir into a passively operated microfluidic device made of polydimethylsiloxane (PDMS). Fabrication of the reservoir was accomplished through unique PDMS “landscaping” above sampling channels, with a design strategy targeted to primary adipocytes to overcome issues of positive cell buoyancy. This reservoir allowed three-dimensional culture of primary murine adipocytes, accurate control over stimulants via constant perfusion, and sampling of adipokine secretion during various treatments. As the first report of primary adipocyte culture and sampling within microfluidic systems, this work sets the stage for future studies in adipokine secretion dynamics. PMID:25423362

    An efficient strategy, based on a combination of procedures, was developed to obtain axenic cultures from field-collected samples of the cyanobacterium Phormidium animalis. Samples were initially cultured in solid ASN-10 medium, and a crude separation of major contaminants from P. animalis filaments was achieved by washing in a series of centrifugations and resuspensions in liquid medium. Then, manageable filament fragments were obtained by probe sonication. Fragmentation was followed by forceful washing, using vacuum-driven filtration through an 8-microm pore size membrane and an excess of water. Washed fragments were cultured and treated with a sequential exposure to four different antibiotics. Finally, axenic cultures were obtained from serial dilutions of treated fragments. Monitoring under microscope examination and by inoculation in Luria-Bertani (LB) agar plates indicated either axenicity or the degree of contamination throughout the strategy. PMID:15003694

    High-throughput cultivation (HTC) based on a dilution-to-extinction method has been applied broadly to the cultivation of marine bacterial groups, which has often led to the repeated isolation of abundant lineages such as SAR11 and oligotrophic marine gammaproteobacteria (OMG). In this study, to expand the phylogenetic diversity of HTC isolates, we performed a large-scale HTC with a single surface seawater sample collected from the East Sea, the Western Pacific Ocean. Phylogenetic analyses of the 16S rRNA genes from 847 putative pure cultures demonstrated that some isolates were affiliated with not-yet-cultured clades, including the OPB35 and Puniceicoccaceae marine group of Verrucomicrobia and PS1 of Alphaproteobacteria. In addition, numerous strains were obtained from abundant clades, such as SAR11, marine Roseobacter clade, OMG (e.g., SAR92 and OM60), OM43, and SAR116, thereby increasing the size of available culture resources for representative marine bacterial groups. Comparison between the composition of HTC isolates and the bacterial community structure of the seawater sample used for HTC showed that diverse marine bacterial groups exhibited various growth capabilities under our HTC conditions. The growth response of many bacterial groups, however, was clearly different from that observed with conventional plating methods, as exemplified by numerous isolates of the SAR11 clade and Verrucomicrobia. This study showed that a large number of novel bacterial strains could be obtained by an extensive HTC from even a small number of samples. PMID:26573832

    We investigated Legionella contamination in bath water samples, collected from 68 bathing facilities in Japan, by culture, culture with amoebic co-culture, real-time quantitative PCR (qPCR), and real-time qPCR with amoebic co-culture. Using the conventional culture method, Legionella pneumophila was detected in 11 samples (11/68, 16.2%). Contrary to our expectation, the culture method with the amoebic co-culture technique did not increase the detection rate of Legionella (4/68, 5.9%). In contrast, a combination of the amoebic co-culture technique followed by qPCR successfully increased the detection rate (57/68, 83.8%) compared with real-time qPCR alone (46/68, 67.6%). Using real-time qPCR after culture with amoebic co-culture, more than 10-fold higher bacterial numbers were observed in 30 samples (30/68, 44.1%) compared with the same samples without co-culture. On the other hand, higher bacterial numbers were not observed after propagation by amoebae in 32 samples (32/68, 47.1%). Legionella was not detected in the remaining six samples (6/68, 8.8%), irrespective of the method. These results suggest that application of the amoebic co-culture technique prior to real-time qPCR may be useful for the sensitive detection of Legionella from bath water samples. Furthermore, a combination of amoebic co-culture and real-time qPCR might be useful to detect viable and virulent Legionella because their ability to invade and multiply within free-living amoebae is considered to correlate with their pathogenicity for humans. This is the first report evaluating the efficacy of the amoebic co-culture technique for detecting Legionella in bath water samples. PMID:26492259

  15. Real and Virtual Heritage Historical Astronomical Plate Archives in Sonneberg, Bamberg and Hamburg Observatories, the Evolution of Astrophysics and their Influence on Human Knowledge and Culture

    Kunzmann, Björn

    The rise of astrophysics around 1860 introduced new instruments, methods and research areas. Of course, the increasing number of foundations of new observatories around the world starting at that time was forced by that new scientific discipline, too, but especially by the usage of photographic instruments. At the end of the 19th century the formation and development of photographic methods and techniques had reached a level of sufficient stability for productive usage in astronomy and astrophysics, their new instrumrents, methods and goals. The fundamental meaning of star light analysis for astrophysics by increasing discoveries of Variable Stars and the Systematic search for moving Solar System objects had basically driven the beginning of large photographic sky patrols at that time, using photographic glass plates as detectors and information storages. Sky Patrols, especially systematic long-term monitoring of the whole sky or of well defined selected areas and Sky Surveys were (and still are) an important key method that forced the evolution and progress of astrophysics. Important scientific results by famous astronomers, for example Walter Baade, Cuno Hoffmeister and Harlow Shapley depended on the analysis of photographic plates. Today, there are around 50 photographic plate archives world-wide. Most of them, unfortunately, are in a quite poor condition and not yet digitized. Following Harvard College Observatory with an estimated total of 600,000 plates, Sonneberg observatory harbours the second largest archive world-wide (around 300,000 plates) among other large ones in Germany like Bamberg (40,000 plates) and Hamburg (35,000 plates). These plate archives form an important heritage with a total of roughly two million direct plates and some ten or hundred thousands of spectroscopic plates. A lot of progress has been made by transforming this real heritage to a virtual one by systematic digitisation of the plates, but perhaps only 15% of them have been

    A number of studies have investigated use of extreme (ERS) and acquiescent (ARS) response styles across cultural groups. However, due to within-group heterogeneity, it is important to also examine use of response styles, acculturation, and endorsement of cultural variables at the individual level. This study explores relationships between acculturation, six Mexican cultural factors, ERS, and ARS among a sample of 288 Mexican American telephone survey respondents. Three aspects of acculturation were assessed: Spanish use, the importance of preserving Mexican culture, and interaction with Mexican Americans versus Anglos. These variables were hypothesized to positively associate with ERS and ARS. Participants with higher Spanish use did utilize more ERS and ARS; however, value for preserving Mexican culture and interaction with Mexican Americans were not associated with response style use. In analyses of cultural factors, endorsement of familismo and simpatia were related to more frequent ERS and ARS, machismo was associated with lower ERS among men, and la mujer was related to higher ERS among women. Caballerismo was marginally associated with utilization of ERS among men. No association was found between la mujer abnegada and ERS among women. Relationships between male gender roles and ARS were nonsignificant. Relationships between female gender roles and ARS were mixed but trended in the positive direction. Overall, these findings suggest that Mexican American respondents vary in their use of response styles by acculturation and cultural factors. This usage may be specifically influenced by participants' valuing of and engagement with constructs directly associated with social behavior. PMID:21927503

    This first in a series of articles on the Chemical Heritage Foundation will outline a brief history of the foundation and give an overview of its present programs, with emphasis on the Othmer Library of Chemical History. The Chemical Heritage Foundation (CHF) is a unique asset and unique partnership of the chemical community. It had its origins in a simple written agreement some 15 years ago, in January 1982. CHF's mission of recording, preserving, and making known the heritage of chemical achievement does not reflect the concerns of the chemical corporations or of anyone directly concerned with the "image" or economic and political future of the chemical sciences. Rather, it was an idea of academics and professional scientists. Thus it was appropriate that the three founding organizations were the American Chemical Society, the American Institute of Chemical Engineers and the University of Pennsylvania.

    Respiratory tract infections with nontuberculous mycobacteria (NTM) are increasing in prevalence and are a significant cause of lung function decline in individuals with cystic fibrosis (CF). NTM have been detected in culture-independent analyses of CF airway microbiota at lower rates than would be expected based on published prevalence data, likely due to poor lysing of the NTM cell wall during DNA extraction. We compared a standard bacterial lysis protocol with a modified method by measuring NTM DNA extraction by qPCR and NTM detection with bacterial 16S rRNA gene sequencing. The modified method improved NTM DNA recovery from spiked CF sputum samples by a mean of 0.53 log10 copies/mL for M. abscessus complex and by a mean of 0.43 log10 copies/mL for M. avium complex as measured by qPCR targeting the atpE gene. The modified method also improved DNA sequence based NTM detection in NTM culture-positive CF sputum and bronchoalveolar lavage samples; however, both qPCR and 16S rRNA gene sequencing remained less sensitive than culture for NTM detection. We highlight the limitations of culture-independent identification of NTM from CF respiratory samples, and illustrate how alterations in the bacterial lysis and DNA extraction process can be employed to improve NTM detection with both qPCR and 16S rRNA gene sequencing.

  2. Archaeoastronomical Heritage and the World Heritage Convention

    NASA Astrophysics Data System (ADS)

    Cotte, Michel

    In 2009, the International Astronomical Union (IAU) and the International Council on Monuments and Sites (ICOMOS) began a joint thematic study on astronomical heritage. The initial question was, "What are the best ways to support and encourage the inscription of the most outstanding examples of astronomical heritage onto a globally balanced World Heritage List?" That led us first to a large overview across ages and countries, because every civilization had a relationship with the sky. The result is far beyond what was anticipated, showing a richness and diversity of heritage, both for various civilizations around the world and throughout human history, especially for the proto-historical period and indigenous practices of observing the sky. This chapter also reviews the World Heritage Convention, its goals, evaluation tools, and trends. A strategy must be created for a credible dossier in the UNESCO-recommended format, with proper identification of "outstanding universal value" (OUV) as a key point for the World Heritage listing. To assist in reaching such ambitious goals, this chapter examines the layout of the convention related to astronomical and archaeoastronomical heritage, though the main requirements need to be recognized. A methodology is proposed for site analysis by examples and practices of the World Heritage Convention, with a description of its origins, favorite subjects, and recent evolutions. Pure astronomical heritage is rare on the World Heritage List, but astronomy is frequently present as an associated value for complex sites and as a specific attribute that increases a global sense of the heritage.

    Methanogenic hydrocarbon metabolism is a key process in subsurface oil reservoirs and hydrocarbon-contaminated environments and thus warrants greater understanding to improve current technologies for fossil fuel extraction and bioremediation. In this study, three hydrocarbon-degrading methanogenic cultures established from two geographically distinct environments and incubated with different hydrocarbon substrates (added as single hydrocarbons or as mixtures) were subjected to metagenomic and 16S rRNA gene pyrosequencing to test whether these differences affect the genetic potential and composition of the communities. Enrichment of different putative hydrocarbon-degrading bacteria in each culture appeared to be substrate dependent, though all cultures contained both acetate- and H2-utilizing methanogens. Despite differing hydrocarbon substrates and inoculum sources, all three cultures harbored genes for hydrocarbon activation by fumarate addition (bssA, assA, nmsA) and carboxylation (abcA, ancA), along with those for associated downstream pathways (bbs, bcr, bam), though the cultures incubated with hydrocarbon mixtures contained a broader diversity of fumarate addition genes. A comparative metagenomic analysis of the three cultures showed that they were functionally redundant despite their enrichment backgrounds, sharing multiple features associated with syntrophic hydrocarbon conversion to methane. In addition, a comparative analysis of the culture metagenomes with those of 41 environmental samples (containing varying proportions of methanogens) showed that the three cultures were functionally most similar to each other but distinct from other environments, including hydrocarbon-impacted environments (for example, oil sands tailings ponds and oil-affected marine sediments). This study provides a basis for understanding key functions and environmental selection in methanogenic hydrocarbon-associated communities. PMID:25734684

    A PCR procedure has been developed for routine analysis of viable Salmonella spp. in feed samples. The objective was to develop a simple PCR-compatible enrichment procedure to enable DNA amplification without any sample pretreatment such as DNA extraction or cell lysis. PCR inhibition by 14 different feed samples and natural background flora was circumvented by the use of the DNA polymerase Tth. This DNA polymerase was found to exhibit a high level of resistance to PCR inhibitors present in these feed samples compared to DyNAzyme II, FastStart Taq, Platinum Taq, Pwo, rTth, Taq, and Tfl. The specificity of the Tth assay was confirmed by testing 101 Salmonella and 43 non-Salmonella strains isolated from feed and food samples. A sample preparation method based on culture enrichment in buffered peptone water and DNA amplification with Tth DNA polymerase was developed. The probability of detecting small numbers of salmonellae in feed, in the presence of natural background flora, was accurately determined and found to follow a logistic regression model. From this model, the probability of detecting 1 CFU per 25 g of feed in artificially contaminated soy samples was calculated and found to be 0.81. The PCR protocol was evaluated on 155 naturally contaminated feed samples and compared to an established culture-based method, NMKL-71. Eight percent of the samples were positive by PCR, compared with 3% with the conventional method. The reasons for the differences in sensitivity are discussed. Use of this method in the routine analysis of animal feed samples would improve safety in the food chain. PMID:14711627

    It has been argued that people in areas with high pathogen loads will be more likely to avoid outsiders, to be biased in favor of in-groups, and to hold collectivist and conformist values. Cross-national studies have supported these predictions. In this paper we provide new pathogen codes for the 186 cultures of the Standard Cross-Cultural Sample and use them, together with existing pathogen and ethnographic data, to try to replicate these cross-national findings. In support of the theory, we found that cultures in high pathogen areas were more likely to socialize children toward collectivist values (obedience rather than self-reliance). There was some evidence that pathogens were associated with reduced adult dispersal. However, we found no evidence of an association between pathogens and our measures of group bias (in-group loyalty and xenophobia) or intergroup contact. PMID:23389437

    Blastocystis species are enteric protozoa frequently detected in human and animals. Seventeen subtypes (STs) have now been identified, nine of them isolating from humans. The pleomorphic structure and genetic diversity of Blastocystis spp. and the absence of standardized diagnostic methods complicate the evaluation of current data. Microscopic methods such as native-lugol and trichrome staining are most frequently used methods in routine diagnosis, while culture and molecular methods are preferred for research purposes. The aims of this study were to investigate the presence of Blastocystis spp. in the stool samples of patients with gastrointestinal complaints by microscopic and culture methods, and to detect the subtypes of isolates by polymerase chain reaction (PCR). A total of 350 stool samples collected from patients with diarrhea (n= 157) and without diarrhea (n= 193) were included in the study. Presence of Blastocystis spp. in the samples were investigated by native-lugol examination, trichrome staining and direct fluorescent antibody (DFA) methods. Ringer's solution containing 10% horse serum and 0.05% asparagine was used for cultivation. The cultures were evaluated after 3-4 days of incubation at 37°C by microscopic examination. The subtypes of Blastocystis spp. strains isolated from the cultures have been identified by PCR using sequence-tagged site primers. A total of 66 (19%) stool samples, of them 26 (16.6%) were from diarrheal and 40 (21%) from non-diarrheal cases, yielded Blastocystis sp. growth in culture. Among the evaluated samples, 12% (42/350) were found positive with native-lugol examination, 17% (58/350) with trichrome staining, and 19% (66/350) with DFA method. The agreement of culture and native-lugol method was estimated as strong (κ= 0.752), while it was very strong between culture with trichrome staining and DFA methods (κ= 0.922 and κ= 1.00, respectively). When the culture was accepted as reference method, the sensitivity and

    This paper will look at the requirements for a future vision of networked, digital heritage inventories to support heritage protection in England. The present loose network presents several challenges for multiple organizations maintaining similar datasets on disparate IT software: Duplication of content; ownership of content and different approaches to recording practice and standards. This paper will discuss the potential use of the Arches Heritage Inventory and Management System as part of the vision for better operation of this network. Arches was developed by the Getty Conservation Institute, World Monuments Fund and Farallon Geographics as an open source web-based geographic information system (GIS) to help inventorize and manage immovable cultural heritage. The system is based around internationally recognized standards from both the heritage and IT sectors. These include: ISO 21127: 2006, commonly referred to as the CIDOC-CRM (Conceptual Reference Model); the CIDOC Core Data Standard for Archaeological and Architectural Sites; Core Data Index to Historic Buildings and Monuments of the Architectural Heritage as well as Open Geospatial Consortium (OGC) standards. The proposed use of Arches as a data collection and exchange platform would provide effective and useful recording systems for small heritage projects lacking in-house IT support and the finances and skills to support their development. In addition it would promote standards to support cross-searching, data exchange and digital archiving and through its use of open source a community of IT developers, standards developers and content specialists can be developed to sustain the network.

Z-lab and HoLoFoS were developed to meet identified prerequisites of holographic recording of artifacts: a) in situ recording b) a high degree of detail and color reproduction c) a low degree of image distortions. The Z-Lab consists of the Z3RGB camera, its accessories and a mobile darkroom. HoLoFoS is an RGB LED-based lighting device for the display of color holograms. The device is capable of digitally controlled intensity mixing and provides a beam of uniform color cross section. The small footprint and emission characteristics of the device LEDs result in a narrow band, quasi point source at selected wavelengths. A case study in recording and displaying 'Optical Clones' of Greek cultural heritage artifacts with the aforementioned systems will also be presented.

    This study aimed to develop a solid culture medium for differential isolation of the probiotic strain Lactobacillus casei Shirota (LcS) and for selective cultivation of lactobacilli present in oral samples. Type strains of lactobacilli and isolates from commercial probiotic products were inoculated onto modified de Man Rogosa Sharpe agar (termed 'LcS Select'), containing bromophenol blue pH indicator, vancomycin and reducing agent L-cysteine hydrochloride for differential colony morphology development. L. casei Shirota cultured on the novel medium produced distinctive colony morphologies, different from other lactobacilli tested. LcS-characteristic colonies were recovered on LcS Select medium from samples of saliva and tongue plaque following a four-week probiotic intervention study. The viable count of presumptive LcS colonies correlated with those isolated on a non-commercial lactitol-LBS-vancomycin agar (LLV) developed for a selective isolation of LcS from faeces. The novel LcS Select medium proved suitable for differential isolation of the probiotic strain L. casei Shirota from oral samples containing mixed microbial populations. It can also be used for selective growth of vancomycin-resistant lactobacilli. There are few available culture media that are sufficiently selective to enable isolation of probiotic strains from mixed populations. LcS Select medium provides a cheaper, yet effective tool in this context. PMID:22484087

    The use of whole-genome sequencing as a tool for the study of infectious bacteria is of growing clinical interest. Chlamydia trachomatis is responsible for sexually transmitted infections and the blinding disease trachoma, which affect hundreds of millions of people worldwide. Recombination is widespread within the genome of C. trachomatis, thus whole-genome sequencing is necessary to understand the evolution, diversity, and epidemiology of this pathogen. Culture of C. trachomatis has, until now, been a prerequisite to obtain DNA for whole-genome sequencing; however, as C. trachomatis is an obligate intracellular pathogen, this procedure is technically demanding and time consuming. Discarded clinical samples represent a large resource for sequencing the genomes of pathogens, yet clinical swabs frequently contain very low levels of C. trachomatis DNA and large amounts of contaminating microbial and human DNA. To determine whether it is possible to obtain whole-genome sequences from bacteria without the need for culture, we have devised an approach that combines immunomagnetic separation (IMS) for targeted bacterial enrichment with multiple displacement amplification (MDA) for whole-genome amplification. Using IMS-MDA in conjunction with high-throughput multiplexed Illumina sequencing, we have produced the first whole bacterial genome sequences direct from clinical samples. We also show that this method can be used to generate genome data from nonviable archived samples. This method will prove a useful tool in answering questions relating to the biology of many difficult-to-culture or fastidious bacteria of clinical concern. PMID:23525359

    2013-07-01

    The ancient oasis-city of Al Ain in Abu Dhabi Emirate still retains the most important and outstanding cultural heritage of United Arab Emirates (UAE). The larger area of Abu Dhabi Emirate comprised of archaeological sites, cultural landscapes and historic buildings dating back to 3rd millennium to the recent pre-oil era. Traditional materials like stone, earth and palm wood were used in combination with local construction methods. For the last seven years the newly formed Abu Dhabi Tourism & Culture Authority (TCA Abu Dhabi)1 has been actively involved in conservation of built heritage in Abu Dhabi Emirate with the help of its Conservation Section. Documentation prior to any conservation and restoration works is considered as a basic pre-requisite for understanding an historic building or site. It is a process which continues during the conservation of any monument and is the only accurate tool for recording information in order to understand the structure, ultimately leading to the management of cultural heritage. Application and use of tools, ranging from basic manual techniques to 3D laser scanning, based on the best practices and international guidelines the exercise will help in establishing a documentation lab with standard procedures, specifications and tools for the documentation and monitoring the built heritage of Abu Dhabi Emirate. This paper will discuss a range of case studies and will demonstrate how documentation and monitoring of the built heritage has augmented the various conservation initiatives on a variety of building types.

  17. The Cape Observatory: all Categories of Heritage

    NASA Astrophysics Data System (ADS)

    Glass, Ian S.

    2012-09-01

    In this presentation I will give an outline of the various types of heritage related to the Royal Observatory, Cape of Good Hope, established in 1820 and now the headquarters campus of the South African Astronomical Observatory, located quite close to downtown Cape Town. In terms of tangible, fixed heritage, the campus itself, the domes and the various other buildings are obviously relevant. This category includes the Classical Revival Main Building of 1828 and the McClean dome of 1895 by the leading colonial architect Herbert Baker as well as many other buildings and even the graves of two directors. Tangible movable items include, in principle, the telescopes, the accessory instruments and many pieces of apparatus that have been preserved. In addition, extensive collections of antique paintings, drawings, furniture and books add to the site's cultural significance. Many of the Observatory's archives are still kept locally. The intangible heritage of the Observatory consists for example of its history, its major discoveries, its interaction with the City, its central role in the history of science in South Africa and its appeal as a living cultural institution. Especially notable were the observations by Henderson (ca 1831) leading to the distance of a Cen and the early sky survey known as the Cape Photographic Durchmusterung.

    This study is one of the few investigations which analyze albumen prints, perhaps the most important photographic heritage of the late 19(th) and early 20(th) centuries. The chemical composition of photographic samples was assessed using Fourier-transform infrared spectroscopy and X-ray fluorescence. These two non-invasive techniques revealed the complex nature of albumen prints, which are composed of a mixture of proteins, cellulose and salts. Microbial sampling was performed using cellulose nitrate membranes which also permitted the trapped microflora to be observed with a scanning electron microscope. Microbial analysis was performed using the combination of culture-dependent (cultivation in different media, including one 3% NaCl) and culture-independent (bacterial and fungal cloning and sequencing) approaches. The isolated microorganisms were screened for their lipolytic, proteolytic, cellulolytic, catalase and peroxidase activities. The combination of the culture-dependent and -independent techniques together with enzymatic assays revealed a substantial microbial diversity with several deteriogen microorganisms from the genera Bacillus, Kocuria, Streptomyces and Geobacillus and the fungal strains Acrostalagmus luteoalbus, Bjerkandera adusta, Pleurotus pulmonarius and Trichothecium roseum.

    This paper discusses a common reality in many cases of multilingualism: heritage speakers, or unbalanced bilinguals, simultaneous or sequential, who shifted early in childhood from one language (their heritage language) to their dominant language (the language of their speech community). To demonstrate the relevance of heritage linguistics to the study of linguistic competence more broadly defined, we present a series of case studies on heritage linguistics, documenting some of the deficits and abilities typical of heritage speakers, together with the broader theoretical questions they inform. We consider the reorganization of morphosyntactic feature systems, the reanalysis of atypical argument structure, the attrition of the syntax of relativization, and the simplification of scope interpretations; these phenomena implicate diverging trajectories and outcomes in the development of heritage speakers. The case studies also have practical and methodological implications for the study of multilingualism. We conclude by discussing more general concepts central to linguistic inquiry, in particular, complexity and native speaker competence. PMID:26500595

    2013-07-01

    This paper examines use of multi-media in the curation, presentation and promotion of rock art. It discusses the construction of a centralised Australian rock art database and explores new technologies available for looking at rock art. In 2011, Prof. Taçon Chair in Rock Art Research and Director of PERAHU (Place, Evolution and Rock Art Heritage Unit) called for a national rock art database raising awareness of the importance of preserving rock art as part of Australia's valuable Indigenous heritage (Taçon, 2011). Australia has over 100,000 rock art sites, important heritage places for Indigenous and non-Indigenous Australians and a testament to over 10,000 years of human activity, including interactions with other peoples and the environment. Many of these sites have not been documented or recorded and are threatened by natural and cultural agents. It is becoming increasingly important to develop conservation models for the protection and preservation of sites. Indigenous cultural heritage is difficult to manage on a local government level due to complex human / time / environment relationships and the importance of intangible cultural heritage (SoE SEWPAC, 2011). Currently no centralised database system exists in Australia to curate, present and promote rock art.

    The rapid, sensitive, and specific identification of infectious pathogens from clinical isolates is a critical need in the hospital setting. Mass spectrometry (MS) has been widely adopted for identification of bacterial pathogens, although polymerase chain reaction remains the mainstay for the identification of viral pathogens. Here, we explored the capability of MS for the detection of human metapneumovirus (HMPV), a common cause of respiratory tract infections in children. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) sequencing of a single HMPV reference strain (CAN97-83) was used to develop a multiple reaction monitoring (MRM) assay that employed stable isotope-labeled peptide internal standards for quantitation of HMPV. Using this assay, we confirmed the presence of HMPV in viral cultures from 10 infected patients and further assigned genetic lineage based on the presence/absence of variant peptides belonging to the viral matrix and nucleoproteins. Similar results were achieved for primary clinical samples (nasopharyngeal aspirates) from the same individuals. As validation, virus lineages, and variant coding sequences, were confirmed by next-generation sequencing of viral RNA obtained from the culture samples. Finally, separate dilution series of HMPV A and B lineages were used to further refine and assess the robustness of the assay and to determine limits of detection in nasopharyngeal aspirates. Our results demonstrate the applicability of MRM for identification of HMPV, and assignment of genetic lineage, from both viral cultures and clinical samples. More generally, this approach should prove tractable as an alternative to nucleic-acid based sequencing for the multiplexed identification of respiratory virus infections. PMID:26376123

    Besides wildlife tourism in the African savannah, cultural heritage tourism (sometimes known only as heritage tourism) is a big draw in Tanzania. In order to attract cultural tourism dollars, Maasai communities have established cultural bomas, typically pseudo Maasai villages where they display cultural performances and crafts before tourists. Such cultural contact has resulted in the growing influence of globalization that challenges traditional ways. The economic, social and environmental impact of heritage tourism on intergenerational relationships and community well-being has not been examined among the Maasai people. In this study, focus groups were conducted with different age-groups of Maasai people residing in Esilalei and Oltukai villages. Results suggest that for the Maasai, heritage tourism appears to be a double-edged sword. While tourism results in some trickled down economic benefits for the Maasai community, economic change appears to have created a social distance between generations. PMID:24390314

    IRENI (infrared environmental imaging) is a recently commissioned Fourier transform infrared (FTIR) chemical imaging beamline at the Synchrotron Radiation Center in Madison, WI, USA. This novel beamline extracts 320 mrad of radiation, horizontally, from one bending magnet. The optical transport separates and recombines the beam into 12 parallel collimated beams to illuminate a commercial FTIR microspectrometer (Bruker Hyperion 3000) equipped with a focal plane array detector where single pixels in the detector image a projected sample area of either 0.54×0.54 μm2 or 2×2 μm2, depending in the measurement geometry. The 12 beams are partially overlapped and defocused, similar to wide-field microscopy, homogeneously illuminating a relatively large sample area compared to single-beam arrangements. Both transmission and reflection geometries are used to examine a model cross section from a layered polymer material. The compromises for sample preparation and measurement strategies are discussed, and the chemical composition and spatial definition of the layers are distinguished in chemical images generated from data sets. Deconvolution methods that may allow more detailed data analysis are also discussed.

    In clinical trials investigating human health and in the analysis of microbial communities in cultures and natural environments, it is a substantial challenge to differentiate between living, potentially active communities and dead cells. The DNA-intercalating dye propidium monoazide (PMA) enables the selective masking of DNA from dead, membrane-compromised cells immediately before DNA extraction. In the present study, we evaluated for the first time a PMA treatment for methanogenic archaea in cultures and particle-rich environmental samples. Using microscopic analyses, we confirmed the applicability of the LIVE/DEAD(®) BacLight™ kit to methanogenic archaea and demonstrated the maintenance of intact cell membranes of methanogens in the presence of PMA. Although strain-specific differences in the efficiency of PMA treatment to methanogenic archaea were observed, we developed an optimal procedure using 130 μM PMA and 5min of photo-activation with blue LED light. The results showed that the effectiveness of the PMA treatment strongly depends on the texture of the sediment/soil: silt and clay-rich sediments represent a challenge at all concentrations, whereas successful suppression of DNA from dead cells with compromised membranes was possible for low particle loads of sandy soil (total suspended solids (TSS)≤200 mg mL(-1)). Conclusively, we present two strategies to overcome the problem of insufficient light activation of PMA caused by the turbidity effect (shielding) in particle-rich environmental samples by (i) dilution of the particle-rich sample and (ii) detachment of the cells and the free DNA from the sediment prior to a PMA treatment. Both strategies promise to be usable options for distinguishing living cells and free DNA in complex environmental samples. PMID:26656002

    Background Brucellosis is a zoonosis disease which is widespread across the world. Objectives The aim of the present study is the evaluation of culture-negative blood samples. Materials and Methods A total of 100 patients with suspected brucellosis were included in this experimental study and given positive serological tests. Diagnosis was performed on patients with clinical symptoms of the disease, followed by the detection of a titer that was equal to or more than 1:160 (in endemic areas) by the standard tube agglutination method. Blood samples were cultured by a BACTEC 9050 system, and subsequently by Brucella agar. At the same time, DNA from all blood samples was extracted by Qiagen Kit Company (Qia Amp Mini Kit). A molecular assay of blood samples was carried out by detection of eryD transcriptase and bcsp 31 genes in specific double PCR reactions. The specificity of the primers was evaluated by DNA from pure and approved Brucella colonies found in the blood samples, by DNA from other bacteria, and by ordinary PCR. DNA extraction from the pure colonies was carried out by both Qiagen Kit and Chelex 100 methods; the two were compared. Results 39 cases (39%) had positive results when tested by the BACTEC system, and 61 cases (61%) became negative. 23 culture-positive blood samples were randomly selected for PCR reactions; all showed 491 bp for the eryD gene and 223 bp for the bcsp 31 gene. Interestingly, out of 14 culture-negative blood samples, 13 cases showed positive bonds in PCR. The specificity of the PCR method was equal to 100%. DNA extraction from pure cultures was done by both Chelex 100 and Qiagen Kit; these showed the same results for all samples. Conclusions The results prove that the presented double PCR method could be used to detect positive cases from culture-negative blood samples. The Chelex 100 method is simpler and safer than the use of Qiagen Kit for DNA extraction. PMID:27330831

    Preservation of cells, choice of fixative, storage, and thawing conditions are recurrent issues for the analysis of phytoplankton by flow cytometry. We examined the effects of addition of the surfactant Pluronic F68 to glutaraldehyde-fixed photosynthetic organisms in cultures and natural samples. In particular, we examined cell losses and modifications of side scatter (a proxy of cell size) and fluorescence of natural pigments. We found that different marine phytoplankton species react differently to the action of Pluronic F68. In particular, photosynthetic prokaryotes are less sensitive than eukaryotes. Observed cell losses may result from cell lysis or from cell adhesion to the walls of plastic tubes that are commonly used for flow cytometry analysis. The addition of the surfactant, Pluronic F68, has a positive effect on cells for long-term storage. We recommend to modify current protocols for preservation of natural marine planktonic samples, by fixing them with glutaraldehyde 0.25% (final concentration) and adding Pluronic F68 at a final concentration of 0.01% in the samples before preservation. Pluronic F68 also appears effective for preserving samples without fixation for subsequent sorting, e.g. for molecular biology analyses. © 2014 International Society for Advancement of Cytometry.

    The Central America region hosts a valuable amount of World Heritage Sites (WHS), many of them located in areas of floods, landslides, drought, high winds, intense precipitations, and earthquakes. The effective management of WHS requires the understanding of this type of environmental phenomena and their potential impacts on these sites. The objective of this work is twofold. To make an analysis of some of the atmospheric systems (easterly waves, cold fronts and tropical cyclones [TCs]) hitting Central America, to estimate their effects on socio-economic activities and potential impacts on WHS during the period 2002-2012. The second objective is to identify, for a case study, the potential effects of hydro-meteorological events associated with a tropical storm on the Diquis Delta region in southern Costa Rica. This site, an important unique archeological site of stone spheres, has been proposed by this country as a WHS. To achieve both, public data bases like HURDAT (North Atlantic Hurricane Database), and information from regional newspapers and National Emergency Committees, among other sources, were used for the study of socio-economic impacts caused by these natural hazards. To accomplish the latter, course resolution NCEP/NCAR (National Center for Environmental Prediction/National Center for Atmospheric Research) Reanalysis atmospheric data served to initialize version 5 of a numerical atmospheric mesoscale model (MM5). This approach permitted to obtain higher resolution gridded data for a set of atmospheric variables for a case study associated with the formation of tropical storm Alma upon the Pacific basin. The MM5 resulted winds and precipitation, among other variables, were then used to evaluate potential impacts on the WHS region. Among the systems analyzed for Central America, TCs were the ones that most severely impacted regional social life and worsened the already weak regional economies. During the period analyzed, TCs affected regions where WHS are

  18. The Sensitization of French Observatory Directors to Astronomical Heritage

    2012-09-01

    An inventory of the heritage of historical astronomical observatories was launched in the mid 1990s as part of a collaboration between the Ministry of Research and the Ministry of Culture. This has produced a significant body of knowledge not only on astronomical instruments, but also on the specificities of astronomical sites and on the architecture of observatories. Other major results of this operation are (i) the development of numerous works on the institutional history of observatories and (ii), at the request of a few directors, the protection as "historical monuments" of some buildings and of collections of instruments. Given that knowledge about astronomical heritage is a prerequisite for proper conservation and intelligent outreach, and given also that the protection of such heritage (as historical monuments) is a major asset that bolsters its cultural value, the long term sustainability of such heritage depends on political decisions and the search for financial support. We shall describe the complex administrative situation of French observatories and outline the various actions undertaken recently to sensitize their directors to astronomical heritage issues.

    Since 2008 the AWHWG has, on behalf of the IAU, been working with UNESCO and its advisory bodies to help identify, safeguard and promote cultural properties relating to astronomy and, where possible, to try to facilitate the eventual nomination of key astronomical heritage sites onto the World Heritage List. Unfortunately, the World Heritage Convention only covers fixed sites (i.e., the tangible immovable heritage of astronomy), and a key question for the UNESCO-IAU Astronomy and World Heritage Initiative (AWHI) is the extent to which the tangible moveable and intangible heritage of astronomy (e.g. moveable instruments; ideas and theories) influence the assessment of the tangible immovable heritage. Clearly, in an ideal world we should be concerned not only with tangible immovable heritage but, to quote the AWHWG's own Terms of Reference, ``to help ensure that cultural properties and artefacts significant in the development of astronomy, together with the intangible heritage of astronomy, are duly studied, protected and maintained, both for the greater benefit of humankind and to the potential benefit of future historical research''. With this in mind, the IAU/INAF symposium on ``Astronomy and its Instruments before and after Galileo'' held in Venice in Sep-Oct 2009 recommended that urgent steps should be taken 1. to sensitise astronomers and the general public, and particularly observatory directors and others with direct influence and control over astronomical resources, to the importance of identifying, protecting and preserving the various material products of astronomical research and discovery that already have, or have significant potential to acquire, universal value; (N.B. National or regional interests and concerns have no relevance in the assessment of ``universal value'', which, by definition, extends beyond cultural boundaries and, by reasonable expectation, down the generations into the future. 2. to identify modes of interconnectivity between
