    Full Text Available "…with the increasing spread of social media and mobile communication, the social networks of knowledge construction are becoming not only vastly bigger and quicker and less limited by space and time constraints than they have been before, but also more of a threat to established authorities." (Hofheinz 2011, 1426 This article considers the issues of archaeological authority, expertise and organisational reputation in the UK from an online perspective, and questions whether the participatory promise of social media technologies can, and should, challenge archaeological authority. It explores how these issues are approached and mediated online, the issues of digital literacy for audience reception, and the approaches used by archaeological organisations to address the challenges of undertaking digital public archaeology projects whilst maintaining archaeological rigour and the visible performance of expertise. It discusses how the concepts of archaeological authority and expertise are demonstrated and practised online, using data from my doctoral research, undertaken from 2011 to 2013. This article questions if the presence of websites dedicated to the promulgation of alternative archaeologies on the Internet can present challenges for the performance of archaeological expertise online, and how organisations monitor and respond to alternative archaeological interpretations and news stories.

  4. Intrinsic limits to gene regulation by global crosstalk

    Gene regulation relies on the specificity of transcription factor (TF)–DNA interactions. Limited specificity may lead to crosstalk: a regulatory state in which a gene is either incorrectly activated due to noncognate TF–DNA interactions or remains erroneously inactive. As each TF can have numerous interactions with noncognate cis-regulatory elements, crosstalk is inherently a global problem, yet has previously not been studied as such. We construct a theoretical framework to analyse the effects of global crosstalk on gene regulation. We find that crosstalk presents a significant challenge for organisms with low-specificity TFs, such as metazoans. Crosstalk is not easily mitigated by known regulatory schemes acting at equilibrium, including variants of cooperativity and combinatorial regulation. Our results suggest that crosstalk imposes a previously unexplored global constraint on the functioning and evolution of regulatory networks, which is qualitatively distinct from the known constraints that act at the level of individual gene regulatory elements.

    Gene activity is mediated by the specificity of binding interactions between special proteins, called transcription factors, and short regulatory sequences on the DNA, where different protein species preferentially bind different DNA targets. Limited interaction specificity may lead to crosstalk: a regulatory state in which a gene is either incorrectly activated due to spurious interactions or remains erroneously inactive. Since each protein can potentially interact with numerous DNA targets, crosstalk is inherently a global problem, yet has previously not been studied as such. We construct a theoretical framework to analyze the effects of global crosstalk on gene regulation, using statistical mechanics. We find that crosstalk in regulatory interactions puts fundamental limits on the reliability of gene regulation that are not easily mitigated by tuning proteins concentrations or by complex regulatory schemes proposed in the literature. Our results suggest that crosstalk imposes a previously unexplored global constraint on the functioning and evolution of regulatory networks, which is qualitatively distinct from the known constraints that act at the level of individual gene regulatory elements. The research leading to these results has received funding from the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (FP7/2007-2013) under REA Grant agreement Nr. 291734 (T.F.) and ERC Grant Nr. 250152 (N.B.).

    Full Text Available L’archéologie des Basses Terres mayas à l’époque classique est riche de données susceptibles de nous renseigner sur plusieurs types de « frontières » sociopolitiques. Si la question des limites territoriales des entités politiques du monde classique constitue, depuis les années 1970, un objectif tout à fait conscient de la recherche, bien d’autres éléments des partitionnements sociopolitiques existent, mais ils n’ont pas reçu, le plus souvent, l’attention qu’ils méritent. L’examen de quelques informations, empruntées aux résultats de projets de recherche collective récents, indique que les démarcations formelles plus ou moins minces durent être rares, qu’il y aurait même eu peu de bornages explicites et que les seuils étaient dotés d’une épaisseur certaine, leur franchissement obéissant à des codes précis et/ou impliquant des comportements ritualisés.The archaeology of the Maya Lowlands of the classical era is rich in data that are likely to have something to teach us about several types of sociopolitical “boundary”. Although research since the 1970s has consciously aimed to address the question of the territorial limits of classical-world political entities, many other elements of sociopolitical partitioning exist, but they have tended not to receive the attention they deserve. The examination of a few pieces of information, borrowed from the results of recent collective research projects, indicates that more-or-less thin formal demarcations must have been rare, that there would even have been few explicit boundary markings, and that the thresholds were endowed with a certain thickness, their crossing obeying precise codes and/or involving ritualised behaviours.

    Forensic protocols and medico-legal techniques are increasingly being employed in investigations of museological material. The final findings of such investigations may reveal interesting facts on historical figures, customs and habits, as well as provide meaningful data for forensic use. Herein we present a case review where forensic experts were requested to identify taxonomic affinities, stage of preservation and provide skeletal analysis of mummified non-human archaeological remains, and verify whether two mummified hands are human or not. The manuscript offers a short review on the process and particularities of radiological species identification, the impact of post-mortem changes in the analysis and imaging of mummified remains as well as the macroscopical interpretation of trauma, pathology and authenticity in mummified remains, which can all turn useful when dealing with forensic cases.

  13. Temporal limits to the archaeological record in arid western NSW, Australia : lessons from OSL and radiocarbon dating of hearths and sediments

    International Nuclear Information System (INIS)

    Fanning, P.; Holdaway, S.

    2001-01-01

    The Western NSW Archaeology Program (WNSWAP) has been investigating surface scatters of Aboriginal stone artefacts and associated heat-retainer hearths in arid northwestern NSW, Australia, since 1995. The research combines new methods for documenting and analysing stone artefact scatters with an understanding of geomorphic landscape dynamics to seek insights into spatial and temporal patterns of Aboriginal occupation of the arid margin of Australia during the Late Holocene. The temporal dimension is dealt with in two ways: by radiocarbon determinations on charcoal from the remains of heat-retainer hearths associated with the artefact scatters, and by using optically simulated luminescence (OSL) and radiocarbon determinations from valley fill sediments to develop a chronology of landscape evolution of the valleys in which the artefacts and hearths are found. The heat-retainer hearths produced a record of just less than 2000 years of activity within the valley of Stud Creek, a 30 square km catchment in Sturt National Park. However, the record is discontinuous, with a gap in heat-retainer hearth construction of 200-400 years occurring between about 800 and 1100 y BP. Examination of patterns of erosion and deposition at the places where the hearths were found, and Bayesian statistical analysis of the radiocarbon determinations, demonstrates that this gap is real and not an artefact of the survey protocol. A discontinuous record is also evident when the sediments that comprise the valley fill upon which the hearths and stone artefact scatters are currently lying are examined. Five major sedimentary units can be identified, providing a record of depositional episodes ranging from modern or post-European back to the Late Pleistocene (about 70,000 years). But, in contrast to the record from the remains of the heat-retainer hearths, erosion is the major determinant of the temporal pattern of landscape change that can be reconstructed from this record. Gaps of up to 10

    2012-01-01

    The combined U-series/electron spin resonance (ESR) dating method was applied to nine teeth from two Early Pleistocene archaeological sites located in the Orce area (Guadix-Baza Basin, Southern Spain): Fuente Nueva-3 (FN-3) and Barranco Leon (BL). The combination of bio-stratigraphy and magneto-stratigraphy places both sites between the Olduvai and Jaramillo sub-chrons (1.78-1.07 Ma). Our results highlight the difficulty of dating such old sites and point out the limits of the combined U-series/ ESR dating method based on the US model. We identified several sources of uncertainties that may lead to inaccurate age estimates. Seven samples could not be dated because the dental tissues had ( 230 Th/ 234 U) activity ratios higher than equilibrium, indicating that uranium had probably leached from these tissues. It was however possible to calculate numerical estimates for two of the teeth, both from FN-3. One yielded a Middle Pleistocene age that seems to be strongly underestimated; the other provided an age of 1.19±0.21 Ma, in agreement with data obtained from independent methods. The latter result gives encouragement that there are samples that can be used for routine dating of old sites. (authors)

  2. River archaeology - a new tool for historical hydrology

    International Nuclear Information System (INIS)

    Toth, Attila J

    2008-01-01

    River archaeology consists of underwater research on the rivers themselves. It is also concerned with the archaeology of the valleys/floodplains with special attention to human-environmental interactions (reconstructing landscape, the environment, economy and society from material culture and traces of human impact on their surroundings). As historical hydrology is concerned with similar questions, from the hydrologist's point of view, the combination of different approaches offers the possibilities for fruitful cooperation for both disciplines. The intent of this paper is to present the type, nature and limitations of this part of the archaeological record through recent work in the Drava River basin.

  8. Archaeology of Void Spaces

    Science.gov (United States)

    Look, Cory

    The overall goal of this research is to evaluate the efficacy of pXRF for the identification of ancient activity areas at Pre-Columbian sites in Antigua that range across time periods, geographic regions, site types with a variety of features, and various states of preservation. These findings have important implications for identifying and reconstructing places full of human activity but void of material remains. A synthesis for an archaeology of void spaces requires the construction of new ways of testing anthrosols, and identifying elemental patterns that can be used to connect people with their places and objects. This research begins with an exploration of rich middens in order to study void spaces. Midden archaeology has been a central focus in Caribbean research, and consists of an accumulation of discarded remnants from past human activities that can be tested against anthrosols. The archaeological collections visited for this research project involved creating new databases to generate a comprehensive inventory of sites, materials excavated, and assemblages available for study. Of the more than 129 Pre-Columbian sites documented in Antigua, few sites have been thoroughly surveyed or excavated. Twelve Pre-Columbian sites, consisting of thirty-six excavated units were selected for study; all of which contained complete assemblages for comparison and soil samples for testing. These excavations consisted almost entirely of midden excavations, requiring new archaeological investigations to be carried out in spaces primarily void of material remains but within the village context. Over the course of three seasons excavations, shovel test pits, and soil augers were used to obtain a variety of anthrosols and archaeological assemblages in order to generate new datasets to study Pre-Columbian activity areas. The selection of two primary case study sites were used for comparison: Indian Creek and Doigs. Findings from this research indicate that accounting for the

  9. Alchemy or Science? Compromising Archaeology in the Deep Sea

    Science.gov (United States)

    Adams, Jonathan

    2007-06-01

    In the torrid debate between archaeology and treasure hunting, compromise is often suggested as the pragmatic solution, especially for archaeology carried out either in deep water or beyond the constraints that commonly regulate such activities in territorial seas. Both the wisdom and the need for such compromise have even been advocated by some archaeologists, particularly in forums such as the internet and conferences. This paper argues that such a compromise is impossible, not in order to fuel confrontation but simply because of the nature of any academic discipline. We can define what archaeology is in terms of its aims, theories, methods and ethics, so combining it with an activity founded on opposing principles must transform it into something else. The way forward for archaeology in the deep sea does not lie in a contradictory realignment of archaeology’s goals but in collaborative research designed to mesh with emerging national and regional research and management plans.

  11. Reducing Conservatism in Aircraft Engine Response Using Conditionally Active Min-Max Limit Regulators

    Science.gov (United States)

    May, Ryan D.; Garg, Sanjay

    2012-01-01

    Current aircraft engine control logic uses a Min-Max control selection structure to prevent the engine from exceeding any safety or operational limits during transients due to throttle commands. This structure is inherently conservative and produces transient responses that are slower than necessary. In order to utilize the existing safety margins more effectively, a modification to this architecture is proposed, referred to as a Conditionally Active (CA) limit regulator. This concept uses the existing Min-Max architecture with the modification that limit regulators are active only when the operating point is close to a particular limit. This paper explores the use of CA limit regulators using a publicly available commercial aircraft engine simulation. The improvement in thrust response while maintaining all necessary safety limits is demonstrated in a number of cases.

    Full Text Available This study assesses the level of knowledge, interest, and awareness of archaeology among Kuwaiti youth in keeping with the social learning theory (Bandura 1977, which emphasises the social context in which learning takes place. According to this approach, individuals acquire through observation and imitation of significant others key concepts and cultural symbols. This study also focuses on students' perceptions of how the Kuwaiti government implements the archaeology law. Data were collected from a survey conducted in 2015 on a random sample of 1193 students from 12 high schools located in the 6 governorates in Kuwait. Two high schools (representing males and females from each governorate were selected. Emphasis was on students in the senior level of high school (17-18 years old as the last stage in the public schooling system in Kuwait. The study analysed the impact of students' gender, socioeconomic background, and personal exposure to archaeology on their attitudes toward archaeology. Analyses using Chi-square tests along with descriptive statistics revealed that students with highly educated parents and those attending schools in well-to-do communities were more likely to be knowledgeable about, interested in, and aware of the importance of archaeology. Students with personal exposure to archaeology are more interested in and concerned with archaeology than those with no experience. In addition, gender was a significant factor as males showed more knowledge of, interest in, and awareness of archaeology than females.

  16. An Exercise in Theoretical Archaeology: Do Archaeological Cultures Exist?

    Directory of Open Access Journals (Sweden)

    Marko Porčić

    2016-02-01

    Full Text Available Archaeological culture still persists as a basic analytical and interpretative concept in Serbian archaeology despite criticism. This paper presents a formal view of archaeological cultures and explores the epistemological implications of this formalization. Formal analysis of archaeological culture is achieved through logical and quantitative explication of the traditional definition of archaeological cultures. The main result of the formal analysis is that there are real patterns of formal variability of material culture that may or may not correspond to traditional archaeological cultures. These patterns are real only in the analytical sense – they are real for given input data and scale of analysis. Unlike the traditional approach where this patterns are equated with archaeological cultures which are furthered interpreted in essentialist terms or as quasi- organic entities such as ethnic groups, it is claimed here that discovered patterns are only the starting point – the empirical situation that needs to be accounted for in anthropological an historical terms. This paper shows how patterns that are traditionally identified as archaeological cultures can arise as a consequence of an entire range of processes – different social and historical realities. The main conclusion is that the traditional concept of archaeological culture is not useful neither as analytical or interpretative tools for two reasons: 1 traditional cultures are subjectively defined entities with no theoretical justification for the criteria used in their definition and 2 the empirical pattern cannot be an explanation in itself because it is the thing that needs to be explained. Cultural evolutionary (transmission theory is proposed as a general framework for defining and interpreting patterns of formal variability of material culture in time and space.

  17. Potassium-argon dating in archaeology

    Energy Technology Data Exchange (ETDEWEB)

    McDougall, I. (Australian National Univ., Canberra (Australia). Research School of Earth Sciences)

    1990-01-01

    The potassium-argon (K-Ar) isotopic dating method can provide precise and accurate numerical ages on suitable rocks, especially igneous rocks, over a wide range of age from less than 100,000 years old, with no older limit. Together with its variants, the {sup 40}Ar/{sup 39}Ar technique, the K-Ar method is very useful for the numerical age calibration of stratigraphic sequences, including those containing archaeological or fossil material, in cases where appropriate rocks for dating are present. This brief review of the basis of the K-Ar dating method and the underlying assumptions, concludes with an example of its application to the Plio-Pleistocene stratigraphic sequence in the Turkana Basin, northern Kenya. By dating alkali feldspars separated from pumice blocks in tuffaceous beds, excellent age control has been obtained for the wealth of vertebrate fossils, including hominids, as well as archaeological materials that has been found in the sequence.

    Archaeological surveys, limited surface collections and selected test excavations in the Yucca Mountain Project Area have revealed four distinct aboriginal hunting and gathering adaptive strategies and a separate historic Euroamerican occupation. The four aboriginal adaptations are marked by gradual shifts in settlement locations that reflect changing resource procurement strategies. Whereas the earliest hunters and gatherers focused their activities around the exploitation of toolstone along ephemeral drainages and the hunting of game animals in the uplands, the latest aboriginal settlements reflect intensive procurement of early spring plant resources in specific upland environments. The final Euroamerican occupation in the area is marked by limited prospecting activities and travel through the area by early immigrants

    We describe herein, limitations on research at biosafety level 4 (BSL-4) containment laboratories, with regard to biosecurity regulations, safety considerations, research space limitations, and physical constraints in executing experimental procedures. These limitations can severely impact the number of collaborations and size of research projects investigating microbial pathogens of biodefense concern. Acquisition, use, storage, and transfer of biological select agents and toxins (BSAT) are highly regulated due to their potential to pose a severe threat to public health and safety. All federal, state, city, and local regulations must be followed to obtain and maintain registration for the institution to conduct research involving BSAT. These include initial screening and continuous monitoring of personnel, controlled access to containment laboratories, accurate and current BSAT inventory records. Safety considerations are paramount in BSL-4 containment laboratories while considering the types of research tools, workflow and time required for conducting both in vivo and in vitro experiments in limited space. Required use of a positive-pressure encapsulating suit imposes tremendous physical limitations on the researcher. Successful mitigation of these constraints requires additional time, effort, good communication, and creative solutions. Test and evaluation of novel vaccines and therapeutics conducted under good laboratory practice (GLP) conditions for FDA approval are prioritized and frequently share the same physical space with important ongoing basic research studies. The possibilities and limitations of biomedical research involving microbial pathogens of biodefense concern in BSL-4 containment laboratories are explored in this review.

  5. The Apparatus of Digital Archaeology

    2017-06-01

    Full Text Available Digital Archaeology is predicated upon an ever-changing set of apparatuses – technological, methodological, software, hardware, material, immaterial – which in their own ways and to varying degrees shape the nature of Digital Archaeology. Our attention, however, is perhaps inevitably more closely focused on research questions, choice of data, and the kinds of analyses and outputs. In the process we tend to overlook the effects the tools themselves have on the archaeology we do beyond the immediate consequences of the digital. This article introduces cognitive artefacts as a means of addressing the apparatus more directly within the context of the developing archaeological digital ecosystem. It argues that a critical appreciation of our computational cognitive artefacts is key to understanding their effects on both our own cognition and on the creation of archaeological knowledge. In the process, it defines a form of cognitive digital archaeology in terms of four distinct methods for extracting cognition from the digital apparatus layer by layer.

    Photosynthesis down-regulation due to an imbalance between sources and sinks in Citrus leaves could be mediated by excessive accumulation of carbohydrates. However, there is limited understanding of the physiological role of soluble and insoluble carbohydrates in photosynthesis regulation and the elements triggering the down-regulation process. In this work, the role of non-structural carbohydrates in the regulation of photosynthesis under a broad spectrum of source-sink relationships has been investigated in the Salustiana sweet orange. Soluble sugar and starch accumulation in leaves, induced by girdling experiments, did not induce down-regulation of the photosynthetic rate in the presence of sinks (fruits). The leaf-to-fruit ratio did not modulate photosynthesis but allocation of photoassimilates to the fruits. The lack of strong sink activity led to a decrease in the photosynthetic rate and starch accumulation in leaves. However, photosynthesis down-regulation due to an excess of total soluble sugars or starch was discarded because photosynthesis and stomatal conductance reduction occurred prior to any significant accumulation of these carbohydrates. Gas exchange and fluorescence parameters suggested biochemical limitations to photosynthesis. In addition, the expression of carbon metabolism-related genes was altered within 24 h when strong sinks were removed. Sucrose synthesis and export genes were inhibited, whereas the expression of ADP-glucose pyrophosphorylase was increased to cope with the excess of assimilates. In conclusion, changes in starch and soluble sugar turnover, but not sugar content per se, could provide the signal for photosynthesis regulation. In these conditions, non-stomatal limitations strongly inhibited the photosynthetic rate prior to any significant increase in carbohydrate levels.

  8. Luminescence dating in archaeology

    International Nuclear Information System (INIS)

    Wintle, A.G.

    2001-01-01

    Thermoluminescence (TL) dating is routinely applied to burnt lithic material. Simple fires are capable of enabling stones weighing a few hundred grams to reach 450 o C, thus zeroing the TL signal. TL dates have been obtained for Upper and Lower Paleolithic sites in Europe and the Near East. TL dating continues to be used for dating pottery and for authentification of ceramic works of art. Some recent studies report the use of optically stimulated luminescence (OSL) (also know as photoluminescence) for dating very small samples of quartz, e.g. from small pieces of pottery or frm metallurgical slag The major recent advance has been in the development of a reliable laboratory procedure for using the OSL signal from quartz to obtain the past radiation exposure. The quartz OSL signal is extremely sensitive to light and is reduced to a negligible level on exposure to direct sunlight for radionuclides during burial, signal to date san.sized quartz grains extracted from sediments, The OSL signal is stimulated by 470 nm light from emitting diodes and the detected using flirters centred on 340 nm A similar signal can be obtained from feldspar grain when are exposed to infrared wavelengths around 880 nm. The infrared stimulated luminescence (IRSL) signals is also rapidly depleted by exposure to sunlight, and dating of colluvial deposits from archaeological sites has been reported

  9. Information Policy for (Digital Information in Archaeology: current state and suggestions for development

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available The introduction of digital data capturing and management technologies has transformed information practices in archaeology. Digital documentation and digital infrastructures are integrated in archaeologists' daily work now more than ever. International and national institutions and projects have contributed to the development of digital archiving and curation practices. Because knowledge production in archaeology depends heavily on documentation and information dissemination, and on retrieval of past documentation, the question of how information is managed is profoundly intertwined with the possibilities for knowledge production. Regulations at different levels articulate demands and expectations from the emerging digital information practices, but how are these different regulations coordinated, and do they support archaeological knowledge production? In this article we look into the state of information policy - the sum of principles guiding decisions about information - in archaeology and related areas. The aim of the article is to shed light on how information policy directs practice in archaeology, and to show that analysis of such policies is therefore vital. Information policy in legislation and guidelines in Swedish archaeology serves as a case study, and examples from development-led archaeology and the museum sector illustrate how information policies have varied roles across different heritage sectors. There are historical and local trajectories in the policy documents specific to Sweden, but the discussion shows that the emergence of Swedish policies have many parallels with processes in other countries. The article provides recommendations for information policy development for archaeology and related areas.

  10. Archaeology on Screen: Representing Archaeology on Film in Serbia

    Directory of Open Access Journals (Sweden)

    Aleksandar Bandović

    2016-02-01

    Full Text Available Reading the popular culture may contribute to the reflexive view on a discipline such as archaeology. Film, as a part of popular culture, frequently unveils the hidden messages, which may be an echo of a discipline or its distorted image in the mirror. Film and archaeology share not only the common origins in the modernity, but also the imaginary spaces where the past and the present meet and intertwine. The subjects treated in films, the contexts in which archaeology appears, speak of the place the discipline holds in the society, reminding us at the same time of all the elements encompassed by the archaeological discourse. On the other hand, if we compare the portraits of the imaginary archaeologists (such as Professor Mihajlo Pavlović, Vera Zarić, with the witnesses of archaeology in Serbia over the 20th century (Nikola Vulić, Dragoslav Srejović, Milutin Garašanin, we shall approach the meeting point between academic and general public, science and the audience, theory and practice. Extraordinary individuals, unemployed dreamers living at the borders of the worlds, charming connoisseurs of the underworlds – these are but some of the qualities ascribed to the discipline by the films. However, these stereotypes do not generate out of the void, they are the consequence of the self-representation. This mystification of the discipline leads us back to the debate on the responsibility and ethics of the social scientists inside the society they live in. Of course, the suggested reading is one of the many possibilities, one of the archaeological interpretations.

  11. Introduction: Critical Blogging in Archaeology

    2015-05-01

    Full Text Available This special volume of Internet Archaeology collects the leading voices of blogging in archaeology to provide a critical examination of informal, online self-publication. This collection of articles is one result of over a decade of digital communication; the confluence of a conversation that grew from a few lonely voices to a tumultuous cacophony. Even so, blogging has had very little scrutiny in wider archaeological publication (but see Caraher 2008; Kansa and Deblauwe 2011. The first movement toward this volume was the Blogging Archaeology session at the 2011 Society for American Archaeology meetings, accompanied by a "Blog Carnival," a groundbreaking effort to foment reflexive discussion prior to the conference. Several participants of this original session and blog carnival have contributed to this volume; these articles are intermingled with perspectives from contributors who have started blogging in the intervening time, and with peer review comments from archaeologists who have blogged for a long time, and from those who do not blog at all.

  12. Archaeology, museums and virtual reality

    2004-04-01

    Full Text Available This article looks at the idea that the virtual archaeological reconstructions seen in museums cannot be considered Virtual Reality (VR as they are based on an artistic conception of the discipline. The cause is to be found in the origins of Archaeology, which began in the 18th century and was closely linked to the History of Art. In the era of New Technologies, this concept has become both the cause and the consequence: determining the characteristics of VR from within the discipline, whilst simultaneously reinforcing the virtual reconstructions.To assess the relationship between VR and Archaeology, we must first establish a definition of Virtual Reality. Subsequently, we can take a brief look at the history so as to be able to understand the evolution of Archaeology and museums. This leads us to the analysis of some examples of VR in museums, from which we can gain conclusions on the current use of VR. Finally, we look at the possibilities for VR in terms of publicising Archaeology.

  13. Protein Phosphatase 1 Down Regulates ZYG-1 Levels to Limit Centriole Duplication.

    Directory of Open Access Journals (Sweden)

    Nina Peel

    2017-01-01

    Full Text Available In humans perturbations of centriole number are associated with tumorigenesis and microcephaly, therefore appropriate regulation of centriole duplication is critical. The C. elegans homolog of Plk4, ZYG-1, is required for centriole duplication, but our understanding of how ZYG-1 levels are regulated remains incomplete. We have identified the two PP1 orthologs, GSP-1 and GSP-2, and their regulators I-2SZY-2 and SDS-22 as key regulators of ZYG-1 protein levels. We find that down-regulation of PP1 activity either directly, or by mutation of szy-2 or sds-22 can rescue the loss of centriole duplication associated with a zyg-1 hypomorphic allele. Suppression is achieved through an increase in ZYG-1 levels, and our data indicate that PP1 normally regulates ZYG-1 through a post-translational mechanism. While moderate inhibition of PP1 activity can restore centriole duplication to a zyg-1 mutant, strong inhibition of PP1 in a wild-type background leads to centriole amplification via the production of more than one daughter centriole. Our results thus define a new pathway that limits the number of daughter centrioles produced each cycle.

    This paper introduces the design of a l.8 V low dropout voltage regulator (LDO) and a foldback current limit circuit which limits the output current to 3 mA when load over-current occurs. The LDO was implemented in a 0.18 {mu}m CMOS technology. The measured result reveals that the LDO's power supply rejection (PSR) is about -58 dB and -54 dB at 20 Hz and 1 kHz respectively, the response time is 4 {mu}s and the quiescent current is 20 {mu}A. The designed LDO regulator can work with a supply voltage down to 2.0 V with a drop-out voltage of 200 mV at a maximum load current of 240 mA. (semiconductor integrated circuits)

  20. The development of a GIS for New Deal Archaeology

    Bernard K. Means

    2011-05-01

    Full Text Available I have recently launched an effort to create a GIS of all New Deal-funded archaeological investigations conducted in the 48 states that comprised the USA during the Great Depression (Means 2011. This effort was inspired by the persistent notion that New Deal archaeology was largely limited to the southeastern United States, where the generally warmer climate was seen as conducive to the lengthy field seasons that ensured continuous work for the unemployed (Lyon 1996. The large mound sites that dotted the southeastern USA also ensured that there would be sufficient work for the large relief crews seen as ideal from the perspective of federal officials. While it may prove true that the majority of New Deal archaeology was conducted in the southeast, it is also demonstrably true that the various ‘Alphabet Soup’ work relief programs – notably the Civilian Conservation Corps (CCC and the Works Progress Administration/Work Projects Administration (WPA – supported archaeological investigations throughout the USA. In my preliminary efforts to create a GIS for New Deal archaeology, I have determined that at least 75 percent of the 48 states that comprised the USA during the Great Depression had some form of federally funded work relief survey or excavation.

    Full Text Available In this paper I wish to reinforce the view that there is a potential in the use of the Internet by archaeology for an important change in the organisation and institutionalisation of archaeological knowledge. As many have argued, this change involves a shift from hierarchy to networks and flows. But there are dangers that the Internet will simply translate old forms of elite knowledge into new forms, increasingly excluding the un-networked. Care needs to be taken to provide different modes of access for different groups and to find ways round the exclusive tendencies associated with the dispersal of any new technology.

  4. The Times of Archaeology and Archaeologies of Time

    Directory of Open Access Journals (Sweden)

    Andrew Gardner

    2001-11-01

    Full Text Available The subject matter of archaeology as a discipline is explicitly structured by time, and ‘timetravel’ is a common feature of popular discourses about the study of the past. Yet archaeology is also the discipline which, amongst its other theoretical shortcomings, has singularly failed to develop any theory 'of 'time. Chronology is ever-present as a measuring tool, but only in rare cases has there been any consideration of this as but one, culturally-specific kind of temporality among many others experienced by people in their daily lives. In this paper, I will discuss various perspectives on archaeological times, including more sophisticated approaches developed since the later 1980s, and argue for an abandoning of the dualism between ‘measured’ and ‘experienced’ times which has emerged in some of these more critical attempts to grapple with the issue. Time is fundamental to archaeology, but not just because we ‘use’ dates. Rather, archaeologists should be able to contribute to wider discussions of time from their understandings of the materialized temporalities of past human agents, and to develop perspectives on the importance of these to the very nature of human social agency as a form of engagement with the world.

  5. Amino acid limitation induces down-regulation of WNT5a at transcriptional level

    Wang Zuguang; Chen Hong

    2009-01-01

    An aberrant WNT signaling contributes to the development and progression of multiple cancers. WNT5a is one of the WNT signaling molecules. This study was designed to test the hypothesis that amino acid deprivation induces changes in the WNT signaling pathway in colon cancer cells. Results showed that targets of the amino acid response pathway, ATF3 and p21, were induced in the human colon cancer cell line SW480 during amino acid limitation. There was a significant decrease in the WNT5a mRNA level following amino acid deprivation. The down-regulation of WNT5a mRNA by amino acid deprivation is not due to mRNA destabilization. There is a reduction of nuclear β-catenin protein level by amino acid limitation. Under amino acid limitation, phosphorylation of ERK1/2 was increased and the blockage of ERK1/2 by the inhibitor U0126 partially restored WNT5a mRNA level. In conclusion, amino acid limitation in colon cancer cells induces phosphorylation of ERK1/2, which then down-regulates WNT5a expression.

What has previously remained unknown, is that Montelius personally promoted the research undertaken in China by Johan Gunnar Andersson (1874–1960, whose discoveries of Neolithic cultures in the 1920s constituted the breakthrough and starting point for the development of prehistoric archaeology in China. In this paper, we reproduce, translate and discuss a long forgotten memorandum written by Montelius in 1920 in support of Andersson’s research. In this Montelius indicated his belief in the potential of prehistoric Chinese archaeology as well as his predictions regarding the discoveries about to be made. It is therefore an important document for the study of the history of Chinese archaeology as a whole.

    In order to review oil and gas companies' archaeological management systems, the British Columbia Oil and Gas Commission (OGC) introduced its archaeology audit program (AAP) in April 2008. As part of this audit, twenty six oil and gas companies were selected for an office documentation review and a corresponding field audit. This document presented and described these audit results. The purpose of the final audit report was to provide information to assist oil and gas companies to improve their management systems by increasing the emphasis of the preservation of cultural resources. This report presented an overview of the AAP scope and methodology and provided examples from the audit of both good management practices encountered and practices in which opportunities for improvement to archaeological management systems could be implemented. Recommendations to address improvement opportunities were also discussed. It was concluded that the oil and gas companies subject to the audit were found to have met or exceeded OGC expectations for maintaining archaeological management systems. 2 tabs., 7 figs.

  13. History of Latin American Archaeology

    1995-11-01

    Full Text Available Two recent contributions (Oyuela-Caycedo 1994 and Politis 1995 to analyses of the intellectual development of archaeology in Latin America provide us with new perspectives. A theme shared by both is the perception by the authors of a need to distance the development of archaeology in Latin American countries from the overweening influence of Europe and especially U. S. archaeologists. Politis argues that U.S. influence has been tantamount to 'cultural imperialism' (1995:226. He sees U.S. archaeologists as having a history of appropriating and manipulating the knowledge of the past which ignores the local peoples own traditional perceptions of their patrimony, and argues that the U.S. perspective is designed to satisfy the needs of western scholarship but fails to enter a dialog with the legitimate concerns of the subject countries. Oyuela·Caycedo's introductory essay in his book "Nationalism and Archaeology" carries a very similar message. He faults U.S. archaeologists for failing to locate their studies in the areas social and local context, which he sees as leading the U.S. scholars to employ a model derived from "dependency theory" (1994:5, resulting in an overly simplistic perception of the context for the development of archaeological disciplines in respective Latin American countries.

  14. A manufactured past: virtual reality in archaeology

    2004-01-01

    Full Text Available Virtual reality and visualisation technologies developed over the past thirty years have been readily accessible to the archaeological community since the mid 1990s. Despite the high profile of virtual archaeology (Reilly 1991 both within the media and professional archaeology it has not been taken on board as a generally useful and standard technique by archaeologists. In this article we wish to discuss the technical and other issues which have resulted in a reluctance to adopt virtual archaeology and, more importantly, discuss ways forward that can enable us routinely to benefit from this technology in the diversity of archaeological practice.

    The Ikaros transcription factor is essential for early B cell development, but its effect on mature B cells is debated. We show that Ikaros is required to limit the response of naive splenic B cells to B cell receptor signals. Ikaros deficient follicular B cells grow larger and enter cell cycle faster after anti-IgM stimulation. Unstimulated mutant B cells show deregulation of positive and negative regulators of signal transduction at the mRNA level, and constitutive phosphorylation of ERK, p38, SYK, BTK, AKT and LYN. Stimulation results in enhanced and prolonged ERK and p38 phosphorylation, followed by hyper-proliferation. Pharmacological inhibition of ERK and p38 abrogates the increased proliferative response of Ikaros deficient cells. These results suggest that Ikaros functions as a negative regulator of follicular B cell activation.

    2015-12-01

    Full Text Available Over recent decades, the ethics, politics and public engagements of mortuary archaeology have received sustained scrutiny, including how we handle, write about and display the archaeological dead. Yet the burgeoning use of digital media to engage different audiences in the archaeology of death and burial have so far escaped attention. This article explores categories and strategies by which digital media create virtual communities engaging with mortuary archaeology. Considering digital public mortuary archaeology (DPMA as a distinctive theme linking archaeology, mortality and material culture, we discuss blogs, vlogs and Twitter as case studies to illustrate the variety of strategies by which digital media can promote, educate and engage public audiences with archaeological projects and research relating to death and the dead in the human past. The article then explores a selection of key critical concerns regarding how the digital dead are currently portrayed, identifying the need for further investigation and critical reflection on DPMA’s aims, objectives and aspired outcomes.

    2005-01-01

    Purpose: The purpose of this paper was to determine the imaging findings in three 500-year-old Inca mummies and how modern radiology can be used in other sciences such as archaeology. Material and Method: Three naturally mummified children were studied using conventional radiography, dental radiography, CT and puncture biopsies. Working sessions were limited to 20 minutes to prevent thawing of the corpses and radiological techniques were adjusted to their particular anatomic position. Results: CT images showed shrinkaged internal organs due to dehydration. The fatty tissue of the bodies was visibly white because of the transformation of it into adipocere, favoring white matter/gray matter differentiation at the central nervous system. The lungs were expanded in the three corpses and right lung and maxillary sinus pathologies were determined in the older girl. Chronological ages of the three children at the time of their deaths were established. DNA studies determined no family links among them. The spleen was not seen in any case. Conclusions: Modern radiology is an excellent tool in archaeological research. Nutritional state, ages and pathologies of the three mummies were evaluated. (author) [es

  19. Images of Miloje M. Vasić in Serbian Archaeology

    2016-02-01

    Full Text Available Miloje M. Vasić, "the first academically educated archaeologist in Serbia", has a strange destiny in the Serbian archaeology. On the one hand, he has been elevated to the post of the "founding father" of the discipline, with almost semidivine status and iconic importance, while on the other hand, his works have been largely unread and neglected. This paradoxical split is the consequence of the fact that Vasić has been postulated as the universal benchmark of the archaeological practice in Serbia, regardless of his interpretation of the past on the grounds of the archaeological record – the essence of archaeology. Strangely, the life and work of Vasić have not been the subject of much writing, apart from several obituaries, two short appropriate texts (Srejović, Cermanović, and rare articles in catalogues and collections dedicated to the research of Vinča (Garašanin, Srejović, Tasić, Nikolić and Vuković. The critical analysis of his whole interpretive constellation, with "The Ionian colony Vinča" being its brightest star, was limited before the World War II to the rare attempts to rectify the chronology and identify the Neolithic of the Danube valley (Fewkes, Grbić, Holste. After the war, by the middle of the 20th century, the interpretation of Vasić has been put to severe criticism of his students (Garašanin, Milojčić, Benac, which led to the significant paradigm shift, the recognition of the importance of the Balkan Neolithic, and the establishment of the culture-historical approach in the Serbian archaeology. However, from this moment on, the reception of Vasić in the Serbian archaeology has taken a strange route: Vasić as a person gains in importance, but his works are neglected, though referred to, but almost in a cultic fashion, without reading or interpreting them. Rare is a paper on the Neolithic of the Central Balkans that does not call upon the name of Vasić and his four- volume "Vinča", in which Neolithic is not

  20. Pioneers, publishers and the dissemination of archaeological knowledge: A study of publishing in British archaeology 1816-1851

    Sarah Scott

    2013-08-01

    Full Text Available The first half of the nineteenth century was a formative period in the development of archaeology as a discipline and archaeological publishing played a key role in this. Libraries were an essential marker of social and intellectual status and there now exists a considerable body of scholarship on the most impressive publications of the day and on the factors influencing their presentation; for example, in relation to the publication of Mediterranean classical antiquities. The crucial role which publishers played in the selection and dissemination of scholarship has been addressed in recent studies of the history of the book, and there is a growing literature on the role of publishers in the dissemination of scientific knowledge, but there has to date been very limited evaluation of the role of publishers in the selection and dissemination of archaeological knowledge in Britain in this period. This study will investigate the extent to which the publication and dissemination of archaeological knowledge, and hence the discipline itself, was shaped by the intellectual and/or commercial concerns of publishers, with a view to providing a more nuanced understanding of the ways in which knowledge was filtered and the impact that this had. Key trends in archaeological publishing in the period 1816-51 will be identified, based on the London Catalogue of Books, and will show how and why this kind of study should be seen as an essential component of any research which considers the history of the discipline. Selected case studies will show the immense, and previously unacknowledged, importance of decisions made during the publication process on the development of archaeology in Britain, and directions for further study will be identified.

  1. Recent developments on surface contamination limits for packages and conveyances in transport regulations

    2009-01-01

    The IAEA Regulations for the Safe Transport of Radioactive Material [1] contain requirements for contamination limits on packages and conveyances used for the transport of radioactive material. Current contamination limits for packages and conveyances under routine transport conditions have been derived from a model proposed by Fairbairn nearly 50 years ago [3]. This model has proven effective if used with pragmatism, but is based on very conservative as well as extremely simple assumptions which is in no way appropriate any more and which is not compatible with ICRP recommendations regarding radiation protection standards. Therefore, a new model has been developed over the last 8 years which reflects all steps of the transport process. The derivation of this model has been fostered by the IAEA by initiating a Co-ordinated Research Project (see section 2). The results of the calculations using this model could be directly applied as new nuclide specific transport limits for the non-fixed contamination. A corresponding regulatory text has been drafted by an IAEA technical meeting TM-36514, which was held in Tokyo November 10-14, 2008 (see section 4). (orig.)

    Full Text Available Wari and Bateshwar are two adjacent villages in Amlabo Union under Belabo police station in Narsingdi district, Bangladesh. It is situated on an isolated bit of the Pleistocene terrace at Manohardi-Sibpur, which is detached from the Madhupur tract by the Old Brahmaputra and the Laksya rivers. Since the 40s of the last century, a large number of cultural materials of Wari-Bateshwar have been reported from surface collections and chance excavations. Systematic archaeological exploration at the site was carried out in 1998-99 season by the author and subsequently a number of excavations conducted at the site since 2000. Archaeological investigations at Wari-Bateshwar revealed that the site had been occupied from the 4th century BC onwards with occasional breaks. The present paper is the detail report of all the evidences from the archaeological record in the form of physical remains unearthed from explorations and excavations till date and analyzes them to understand the nature and behaviors of the people who produced them. This also places Wari-Bateswar in the macro-level of Indian Ocean maritime trade network during the early historic period.

Was indeed Limes Transalutanus an incomplete limes (lacking civilian settlements, for example, an odd construction (a vallum without fossa, an early-alarm line rather than a proper defensive line? Taking on these historical and archaeological challenges, the team attempts to develop an investigation technology applicable to large scale archaeological landscapes - a full evaluation chain, involving aerial survey, surface survey, geophysical investigation, multispectral images analysis, statistic evaluation and archaeological diggings. This technological chain will be systematically applied on the whole length of the objective, that is, on a 155 km distance. The attempt to find answers to issues related to the earth works’ functionality, layout, structure, chronology and relation with adjacent sites will be grounded on exploring the relations of the monument with the surrounding environment, by focussing on finding methods to reconstruct the features of the ancient landscapes, like systematic drilling, palynological tests and toponymical studies.

  5. Out of the archaeologist's desk drawer: communicating archaeological data online

    During archaeological field work a huge amount of data is collected, processed and elaborated for further studies and scientific publications. However, access and communication of linked data; associated tools for interrogation, analysis and sharing are often limited at the first stage of the archaeological research, mainly due to issues related to IPR. Information is often released months if not years after the fieldwork. Nowadays great deal of archaeological data is `born digital' in the field or lab. This means databases, pictures and 3D models of finds and excavation contexts could be available for public communication and sharing. Researchers usually restrict access to their data to a small group of people. It follows that data sharing is not so widespread among archaeologists, and dissemination of research is still mostly based on traditional pre-digital means like scientific papers, journal articles and books. This project has implemented a web approach for sharing and communication purposes, exploiting mainly open source technologies which allow a high level of interactivity. The case study presented is the newly Mithraeum excavated in Ostia Antica archaeological site in the framework of the Ostia Marina Project.

    The quality of archaeological sites documenting is of great importance for cultural heritage preserving and investigating. The progress in developing new techniques and systems for data acquisition and processing creates an excellent basis for achieving a new quality of archaeological sites documenting and visualization. archaeological data has some specific features which have to be taken into account when acquiring, processing and managing. First of all, it is a needed to gather as full as possible information about findings providing no loss of information and no damage to artifacts. Remote sensing technologies are the most adequate and powerful means which satisfy this requirement. An approach to archaeological data acquiring and fusion based on remote sensing is proposed. It combines a set of photogrammetric techniques for obtaining geometrical and visual information at different scales and detailing and a pipeline for archaeological data documenting, structuring, fusion, and analysis. The proposed approach is applied for documenting of Bosporus archaeological expedition of Russian State Historical Museum.

    Full Text Available The international cultural heritage economy has long been underpinned by a reserve army of unemployed/underemployed labour. The entry-level workforce is being further undermined and unpaid/underpaid labour is additionally being consolidated through the crisis and austerity measures. Independently and under different pressures, archaeologists across Europe have begun to use blogging, micro-blogging and other social media in concerted national efforts to document, analyse and resist exploitative and exclusive employment practices. This article focuses on the development of movements against unpaid labour (free archaeology in the UK, against unpaid and underpaid internship (volontariato and stage in Italy, and for employment (istihdam in Turkey. Using insights gained through observing and participating in these movements, and through running a research blog on precarious labour in the cultural heritage industry, this article examines the benefits and limits of blogging/micro-blogging as a tool for debate within the profession, communication with the public, and activism.

    Full Text Available An optimization based approach for the regulation of excessive or insufficient forces at the end-effector level is introduced. The objective is to minimize the interaction force error at the robot end effector, while constraining undesired interaction forces. To that end, a dynamic optimization problem (DOP is formulated considering a dynamic robot impedance model. Penalty functions are considered in the DOP to handle the constraints on the interaction force. The optimization problem is online solved through the gradient flow approach. Convergence properties are presented and the stability is drawn when the force limits are considered in the analysis. The effectiveness of our proposal is validated via experimental results for a robotic grasping task.

    Histone variants are structural components of eukaryotic chromatin that can replace replication-coupled histones in the nucleosome. The histone variant macroH2A1.1 contains a macrodomain capable of binding NAD + -derived metabolites. Here we report that macroH2A1.1 is rapidly induced during myogenic differentiation through a switch in alternative splicing, and that myotubes that lack macroH2A1.1 have a defect in mitochondrial respiratory capacity. We found that the metabolite-binding macrodomain was essential for sustained optimal mitochondrial function but dispensable for gene regulation. Through direct binding, macroH2A1.1 inhibits basal poly-ADP ribose polymerase 1 (PARP-1) activity and thus reduces nuclear NAD + consumption. The resultant accumulation of the NAD + precursor NMN allows for maintenance of mitochondrial NAD + pools that are critical for respiration. Our data indicate that macroH2A1.1-containing chromatin regulates mitochondrial respiration by limiting nuclear NAD + consumption and establishing a buffer of NAD + precursors in differentiated cells.

    After a general survey of the way in which physics,and indeed chemistry, has opened new vistas archeology these lectures will focus on age determination.Here physics has played a crucial role in providing a timescale prior to recorded history , the latter beginnig about 5000 years ago with the First Dynasty of Egypt and the earliest pyramid. The physics-based timescale was initially provided by radiocarbon dating and this showed the early phases of Neolithic civilisation, e.g.,the earliest Jericho, to have been substiantially more ancient than had been conjectured. Further back in time than the 50000-year limit of that technique other radioisotope methods have been used, as well as electron spin resonance and luminescence; these have been espacially important in dating early human development, notably in throwing light on the relationship of anatomically-modern humans of the Neanderthals. In particular luminescence dating (both thermoluminescence and optically-stimulated luminescence) will be discussed, not o...

    1. Spatial heterogeneity of resources may influence competition among individuals and thus have a fundamental role in shaping population dynamics and carrying capacity. In the present study, we identify shelter opportunities as a limiting resource for juvenile Atlantic salmon (Salmo salar L.). Experimental and field studies are combined in order to demonstrate how the spatial distribution of shelters may influence population dynamics on both within and among population scales. 2. In closed experimental streams, fish performance scaled negatively with decreasing shelter availability and increasing densities. In contrast, the fish in open stream channels dispersed according to shelter availability and performance of fish remaining in the streams did not depend on initial density or shelters. 3. The field study confirmed that spatial variation in densities of 1-year-old juveniles was governed both by initial recruit density and shelter availability. Strength of density-dependent population regulation, measured as carrying capacity, increased with decreasing number of shelters. 4. Nine rivers were surveyed for spatial variation in shelter availability and increased shelter heterogeneity tended to decrease maximum observed population size (measured using catch statistics of adult salmon as a proxy). 5. Our studies highlight the importance of small-scale within-population spatial structure in population dynamics and demonstrate that not only the absolute amount of limiting resources but also their spatial arrangement can be an important factor influencing population carrying capacity.

    The method of PTTL (phototransfer thermoluminescence) dating works satisfactorily over a very wide range of archaeological doses and the upper limit seems to be around 4000 rads. The first TL peak generally occurs at 65deg C or 100deg C in different varieties of quartz and both seem to be satisfactory for PTTL dating if the reading procedure is standardised to take care of the fast fading of these peaks at room temperature.

    A recent announcement of some pyramids, buried under the sand of Egypt and discovered by means of infrared remote sensing, renewed the interest on the archaeological surveys aided by satellites. Here we propose the use of images, obtained from those of Google Maps after some processing to enhance their details, to locate archaeological remains in Egypt.

    In recent years, agencies around the world have invested huge amounts of effort toward digitizing many aspects of the world's cultural heritage. Of particular importance is the digitization of outdoor archaeological sites. In the spirit of valorization of this digital information, many groups have developed virtual or augmented reality (AR) computer applications themed around a particular archaeological object. The problem of pose tracking in outdoor AR applications is addressed. Different positional systems are analyzed, resulting in the selection of a monocular camera-based user tracker. The limitations that challenge this technique from map generation, scale, anchoring, to lighting conditions are analyzed and systematically addressed. Finally, as a case study, our pose tracking system is implemented within an AR experience in the Byblos Roman theater in Lebanon.

  1. [Archaeology and criminology--Strengths and weaknesses of interdisciplinary cooperation].

    Science.gov (United States)

    Bachhiesl, Christian

    2015-01-01

    Interdisciplinary cooperation of archaeology and criminology is often focussed on the scientific methods applied in both fields of knowledge. In combination with the humanistic methods traditionally used in archaeology, the finding of facts can be enormously increased and the subsequent hermeneutic deduction of human behaviour in the past can take place on a more solid basis. Thus, interdisciplinary cooperation offers direct and indirect advantages. But it can also cause epistemological problems, if the weaknesses and limits of one method are to be corrected by applying methods used in other disciplines. This may result in the application of methods unsuitable for the problem to be investigated so that, in a way, the methodological and epistemological weaknesses of two disciplines potentiate each other. An example of this effect is the quantification of qualia. These epistemological reflections are compared with the interdisciplinary approach using the concrete case of the "Eulau Crime Scene".

    2017-04-01

    Archaeology takes the material remains of human activity as the research object, and uses those fragmentary remains to reconstruct the humanistic and natural environment in different historical periods. Space Archaeology is a new branch of the Archaeology. Its study object is the humanistic-natural complex including the remains of human activities and living environments on the earth surface. The research method, space information technologies applied to this complex, is an innovative process concerning archaeological information acquisition, interpretation and reconstruction, and to achieve the 3-D dynamic reconstruction of cultural heritages by constructing the digital cultural-heritage sphere. Space archaeology's attribute is highly interdisciplinary linking several areas of natural and social and humanities. Its task is to reveal the history, characteristics, and patterns of human activities in the past, as well as to understand the evolutionary processes guiding the relationship between human and their environment. This paper summarizes six important aspects of space archaeology and five crucial recommendations for the establishment and development of this new discipline. The six important aspects are: (1) technologies and methods for non-destructive detection of archaeological sites; (2) space technologies for the protection and monitoring of cultural heritages; (3) digital environmental reconstruction of archaeological sites; (4) spatial data storage and data mining of cultural heritages; (5) virtual archaeology, digital reproduction and public information and presentation system; and (6) the construction of scientific platform of digital cultural-heritage sphere. The five key recommendations for establishing the discipline of Space Archaeology are: (1) encouraging the full integration of the strengths of both archaeology and museology with space technology to promote the development of space technologies' application for cultural heritages; (2) a new

  3. Discernibility of Burial Mounds in High-Resolution X-Band SAR Images for Archaeological Prospections in the Altai Mountains

    Full Text Available The Altai Mountains are a heritage-rich archaeological landscape with monuments in almost every valley. Modern nation state borders dissect the region and limit archaeological landscape analysis to intra-national areas of interest. Remote sensing can help to overcome these limitations. Due to its high precision, Synthetic Aperture Radar (SAR data can be a very useful tool for supporting archaeological prospections, but compared to optical imagery, the detectability of sites of archaeological interest is limited. We analyzed the limitations of SAR using TerraSAR-X images in different modes. Based on ground truth, the discernibility of burial mounds was analyzed in different SAR acquisition modes. We show that very-high-resolution TerraSAR-X staring spotlight images are very well suited for the task, with >75% of the larger mounds being discernible, while in images with a lower spatial resolution only a few large sites can be detected, at rates below 50%.

  4. Building archaeology geodatabase in Iraq using GIS

    Full Text Available Geomatics has been an important tool in archaeology. The combination of Geomatics and archaeology adopters have been considered a perfect match, since archaeology often involves the study of the spatial dimension of human behavior over time, and all archaeology carries a spatial component. Since Iraqi archaeology becomes one of the main victims of destruction by negligence and terror attacks, makes our great heritages forgotten. Hence, it is necessary to build a secure database for all Iraqi archeological sites with their two main types (investigated and uninvestigated and rely on digital system by creating digital maps for each Governorate with their archeological database system. Results of archaeological studies are rich in spatial information. GIS is adept at processing these large volumes of data especially those that are geographically referenced. It is effective, accurate and a fast tool. The tools made available through GIS help in data collection, its storage and retrieval, its ability for customization and, finally, the display of the data so that it is visually comprehensible by the user. The most important aspect of GIS in archaeology lies, however, not in its use as a pure map-making tool, but in its capability to merge and analyze

    Full Text Available The European Archaeological Council's working group on 'Making Choices' conducted a survey of EAC member states about the ways in which they make decisions in archaeological heritage management with particular reference to development-led archaeological investigation. The driver for this is the belief that the approaches to development-led archaeology need to be more transparent and proportional to ensure continued state and developer/investor support. Based on a significant response (73% the survey gave a very useful insight into the way in which archaeological sites are defined and inventorised, the processes by which development-led investigations are designed, the means by which information is published and results (and collections archived, and the means by which the public are engaged in the process. The survey identified three key areas where choice-making is very much in the hands of the professional practice. These are: developing a clearer understanding of the significance of protected archaeological sites in the context of Valletta, assessing sensitivity to change for any sites proposed for development, and the design of the investigation itself. In addition, the survey revealed a clear interest in developing better ways of advocating the public value of development-led archaeology. This article summarises the issues raised in the survey and concludes that the most useful ways in which EAC could help its members would be through the preparation of guidance, case studies or toolkits — regardless of what legal or statutory structures are in operation in a given state — on the following subjects: understanding and articulating significance, developing national and regional research frameworks into which new excavations might be integrated, articulating the public value of archaeological investigation and developing better approaches to archaeological archives.

As they do, they are opening up many new possibilities for the conduct and presentation of archaeological research and investigation. The digital realm is one which knows few borders and so the sharing of understanding about these new methods, techniques and possibilities across Europe is extremely valuable'. The Brighton Symposium was held over one-and-a-half days (17-18 March 2016 and consisted of three presentation sessions, followed by discussions that included questions and comments from the floor. The presentations were aimed at one of the three broad themes of the symposium although, in actuality, a number of the presenters raised topics that spanned more than one theme.

    Meso american archaeology works with large amounts of disperse and diverse information, thus the importance of including new methods that optimise the acquisition, conservation, retrieval, and analysis of data to generate knowledge more efficiently and create a better understanding of history. Further, this information --which includes texts, coordinates, raster graphs, and vector graphs-- comes from a considerable geographical area --parts of Mexico, Nicaragua, Honduras and Costa Rica as well as Guatemala, El Salvador and Belize-- is constantly expanding. This information includes elements like shards, buildings, mural paintings, high and low reliefs, topography, maps, and information about the fauna and soil. Grid computing offers a solution to handle all this information: it respects researchers' need for independence while supplying a platform to share, process and compare the data obtained. Additionally, the Grid can enhance space-time analyses with remote visualisation techniques that can, in turn, incorporate geographical information systems and virtual reality. (Author)

    Full Text Available Soviet archaeological expeditions are the main focus of my research. They provide us with very interesting examples of archaeological expeditions as a part of a society, and not only as a part of science. After the 1960s it was an especially popular leisure practice. Many people who were not professional archaeologists went on expeditions in their leisure time and worked there as diggers or shovelmen (excavators. A Soviet archaeologist described them as people who ‘prefer to spend their vacation in archaeological expeditions in various parts of our country instead of seaside resorts.

    It is common in contemporary archaeological literature, in papers at archaeological conferences, and in grant proposals to see heritage professionals use the term LIDAR to refer to high spatial resolution digital elevation models and the technology used to produce them. The goal of this chapter is to break that association and introduce archaeologists to the world of point clouds, in which LIDAR is only one member of a larger family of techniques to obtain, visualize, and analyze three-dimensional measurements of archaeological features. After describing how point clouds are constructed, there is a brief discussion on the currently available software and analytical techniques designed to make sense of them.

    Full Text Available Objective to estimate the efficiency of limit for legionaries as a tool for regulating the Russian transfer market. Methods formal methods of the labor market supply and demand model combinatory analysis statistical methods. Results the article views the order of regulation of the labor relations with foreign legionaries in sports. It is defined that in most countries regulation implies limitation of the number of legionaries who can be claimed for the season or be on the field. The article analyzes the approaches to the transfer market regulation methods as well as the arguments for and against limiting the number of legionaries. Basing on the analysis of literature the author estimates the efficiency of transfer market regulating from the economics viewpoint as well as the results of sports events. The author checks the hypothesis about the inefficiency of the limit as a tool for increasing the quality of the Russian playersrsquo performance based on a number of indicators such as the inefficiency of the national teamrsquos performance number of legionaries their performance etc. The estimation was carried out on the basis of a number of theoretical models 1 model of increasing the footballersrsquo salaries 2 model of free selection of players by the coach and 3 model of quality playersrsquo selection. Basing on these models the hypothesis was disproved of the rapid ldquovictory effectrdquo from the limit ndash the first significant results of the regulation appeared in Russia not earlier than after 10 years. It is supposed that the limit can be explained by G. Akerlofrsquos model by controlling the number of legionaries it is possible to attract more qualified foreign players into the national league. Analysis of the Russian teamsrsquo experience showed that the limit has not resulted in 1 the increase of the legionariesrsquo quality of performance 2 the increase of the playing time of the Russian players on the field in the national

    Lead isotope ratios 206 Pb/ 204 Pb, 207 Pb/ 204 Pb, 208 Pb/ 204 Pb, 207 Pb/ 206 Pb and 208 Pb/ 206 Pb in Japanese galena ores and archaeological bronze objects were determined by a Hitachi RMU-6 mass spectrometer using a rhenium single filament as a surface ionization device. Basic experimental conditions including detection limit, fractionation effect, memory effect, etc. were examined, and the accuracy of determination was checked using the CIT shelf standard No. 1. Archaeological bronze objects were dissolved in nitric acid and lead was extracted by the dithizone method using specially purified reagents in a so-called clean laboratory. When 0.5 μg lead was loaded on the rhenium filament with phosphoric acid and silica gel as stabilizers, an ion current of 10 -13 -- 10 -15 A due to Pb + was obtained and maintained stable for several hours. Coefficients of variation found for the isotope ratios 207 Pb/ 206 Pb and 208 Pb/ 206 Pb were 0.1 -- 0.5%. Lead isotope ratios are given for 17 Japanese galena ores and for archaeological bronze objects such as bronze bells, halberds (Yayoi period), Horyuji pagoda spire (7th century), and Northern Sung coins (11th century). A close resemblance of the isotope ratios was found between Japanese galena ores and some Japanese bronze objects of the 7th century, suggesting the use of the former as raw materials of the latter.

    There is a long history of the application of chemical analysis to archaeological problems, extending to the last years of the 18th century. The nuclear-age technique of neutron activation analysis, permitting the simultaneous, sensitive, non-destructive estimation of many elements in an archaeological specimen, has found wide application. Important advances have been made, using this technique, in locating the origins of archaeological artifacts such as ceramics, metals, obsidian and semiprecious stones, among other articles of ancient ritual and commerce. In addition, the technique of neutron activation analysis has proved to be almost ideal in studies tracing the development of ancient technologies such as glass-making and smelting. In the future, the development of data banks of analyses of archaeological materials should provide an excellent new tool in studies of prehistory.

  18. Forensic archaeology and anthropology : An Australian perspective.

    Science.gov (United States)

    Oakley, Kate

    2005-09-01

    Forensic archaeology is an extremely powerful investigative discipline and, in combination with forensic anthropology, can provide a wealth of evidentiary information to police investigators and the forensic community. The re-emergence of forensic archaeology and anthropology within Australia relies on its diversification and cooperation with established forensic medical organizations, law enforcement forensic service divisions, and national forensic boards. This presents a unique opportunity to develop a new multidisciplinary approach to forensic archaeology/anthropology within Australia as we hold a unique set of environmental, social, and cultural conditions that diverge from overseas models and require different methodological approaches. In the current world political climate, more forensic techniques are being applied at scenes of mass disasters, genocide, and terrorism. This provides Australian forensic archaeology/anthropology with a unique opportunity to develop multidisciplinary models with contributions from psychological profiling, ballistics, sociopolitics, cultural anthropology, mortuary technicians, post-blast analysis, fire analysis, and other disciplines from the world of forensic science.

  3. After Virtual Archaeology: Rethinking Archaeological Approaches to the Adoption of Digital Technology

    Directory of Open Access Journals (Sweden)

    Gareth Beale

    2017-06-01

    Full Text Available In the 1980s archaeologists embraced the rapidly expanding field of computer modelling and visualisation as a vehicle for data exploration. Against this backdrop 'virtual archaeology' was conceived. The term was originally intended to describe a multidimensional approach to the modelling of the (immaterial structures and processes of field archaeology. It described how technology could be harnessed in order to achieve new ways of documenting, interpreting and annotating primary archaeological discoveries and processes. Despite their initial promise, these digital technologies failed to have the impact upon archaeological fieldwork that might have been expected. Even with the prevalence of digital devices on all archaeological excavations, the documentation, interpretation and subsequent narration of archaeological processes have retained their analogue character. While the archaeological record is now primarily digital, its sections, plans, drawings and photographs are facsimiles of the analogue technologies that preceded them. This retention of analogue conventions is increasingly out of step with the general prevalence and diversity of digital technologies as mediators of professional and private life. It is also challenged by 21st-century advances towards technologies that allow for complex engagements with and representations of physical matter and facilitate the interplay between digital and material worlds. This article argues that emerging forms of archaeological practice including gaming, mixed reality, computational photography and additive manufacturing, reveal digital archaeology to be a creative process, blending computational thinking, technological opportunities and established disciplinary traditions. We go on to suggest that digital archaeology, conceived as a form of practice rather than as a toolset, represents a locus for theory generation and critical thinking.

  4. Ceramic compositional analysis in archaeological perspective

    Energy Technology Data Exchange (ETDEWEB)

    Bishop, R.L.; Rands, R.L.; Holley, G.R.

    1980-01-01

    The primary significance of compositional analysis in archaeology lies on the spatial dimension, in distinguishing products made by locally or regionally-based groups. If compositional analysis is to be carried beyond the descriptive recording of similarities and differences, the resource procurement zone (and its geographical relationship to inferred places of manufacture) is a basic operational concept (Rands and Bishop 1980). A zonal concept is clearly indicated in the case of pottery, which frequently is derived from raw materials, clay and temper, that do not necessarily coincide in their place of procurement. Moreover, depending on geomorphological and geochemical variables, these materials may show considerable homogeneity over a fairly extended area. On the other hand, unless there is strong, selective patterning in the exploitation of resources, great heterogeneity within a restricted region may result in fragmented procurement zones that are difficult to equate with the products of specific manufacturing centers. Under favorable circumstances, however, it appears that methods of compositional analysis are approaching the point at which microzones of limited geographical extent can be recognized and assigned heuristically useful boundaries.

  5. Fine particle magnetic mineralogy of archaeological ceramics

    Atkinson, D; King, J A

    2005-01-01

    This study investigated the magnetic mineralogy of a worldwide collection of archaeological pottery. The mineral types, the mass fractions and the domain states of the constituent magnetic fine particles were elucidated from a range of measurements including magnetic hysteresis behaviour, the acquisition of isothermal remanence, low field susceptibility and thermomagnetic curves. The magnetic mineralogy of most samples was dominated by magnetite. Titanomagnetites with limited titanium substitution and cation deficient magnetites (indicative of low temperature oxidation) were dominant in some samples. Haematite was detected in 53% of the samples, but seldom contributed much to the saturation magnetization. Magnetic particle sizes are skewed to smaller sizes, with sherds mostly having a large superparamagnetic or a stable single domain fraction. Low temperature susceptibility data suggest that 30% of samples had some multidomain component. The percentage by mass of magnetic material in the ancient pottery studied was less than 0.8% for all but one of the samples and the majority of samples contain less than 0.3% by weight of magnetic fine particles. The presence of low temperature oxidation in many samples and the occurrence of a multidomain component in a third of the collection suggest that ancient pottery may not always be suitable for determining the intensity of the ancient geomagnetic field

  7. Wildland fire as a self-regulating mechanism: the role of previous burns and weather in limiting fire progression.

    Science.gov (United States)

    Parks, Sean A; Holsinger, Lisa M; Miller, Carol; Nelson, Cara R

    2015-09-01

    Theory suggests that natural fire regimes can result in landscapes that are both self-regulating and resilient to fire. For example, because fires consume fuel, they may create barriers to the spread of future fires, thereby regulating fire size. Top-down controls such as weather, however, can weaken this effect. While empirical examples demonstrating this pattern-process feedback between vegetation and fire exist, they have been geographically limited or did not consider the influence of time between fires and weather. The availability of remotely sensed data identifying fire activity over the last four decades provides an opportunity to explicitly quantify-the ability of wildland fire to limit the progression of subsequent fire. Furthermore, advances in fire progression mapping now allow an evaluation of how daily weather as a top-down control modifies this effect. In this study, we evaluated the ability of wildland fire to create barriers that limit the spread of subsequent fire along a gradient representing time between fires in four large study areas in the western United States. Using fire progression maps in conjunction with weather station data, we also evaluated the influence of daily weather. Results indicate that wildland fire does limit subsequent fire spread in all four study areas, but this effect decays over time; wildland fire no longer limits subsequent fire spread 6-18 years after fire, depending on the study area. We also found that the ability of fire to regulate, subsequent fire progression was substantially reduced under extreme conditions compared to moderate weather conditions in all four study areas. This study increases understanding of the spatial feedbacks that can lead to self-regulating landscapes as well as the effects of top-down controls, such as weather, on these feedbacks. Our results will be useful to managers who seek to restore natural fire regimes or to exploit recent burns when managing fire.

  9. Fission yeast shelterin regulates DNA polymerases and Rad3(ATR kinase to limit telomere extension.

    Directory of Open Access Journals (Sweden)

    Ya-Ting Chang

    2013-11-01

    Full Text Available Studies in fission yeast have previously identified evolutionarily conserved shelterin and Stn1-Ten1 complexes, and established Rad3(ATR/Tel1(ATM-dependent phosphorylation of the shelterin subunit Ccq1 at Thr93 as the critical post-translational modification for telomerase recruitment to telomeres. Furthermore, shelterin subunits Poz1, Rap1 and Taz1 have been identified as negative regulators of Thr93 phosphorylation and telomerase recruitment. However, it remained unclear how telomere maintenance is dynamically regulated during the cell cycle. Thus, we investigated how loss of Poz1, Rap1 and Taz1 affects cell cycle regulation of Ccq1 Thr93 phosphorylation and telomere association of telomerase (Trt1(TERT, DNA polymerases, Replication Protein A (RPA complex, Rad3(ATR-Rad26(ATRIP checkpoint kinase complex, Tel1(ATM kinase, shelterin subunits (Tpz1, Ccq1 and Poz1 and Stn1. We further investigated how telomere shortening, caused by trt1Δ or catalytically dead Trt1-D743A, affects cell cycle-regulated telomere association of telomerase and DNA polymerases. These analyses established that fission yeast shelterin maintains telomere length homeostasis by coordinating the differential arrival of leading (Polε and lagging (Polα strand DNA polymerases at telomeres to modulate Rad3(ATR association, Ccq1 Thr93 phosphorylation and telomerase recruitment.

    This research is focused on the analysis of the potential of a close range aerial photogrammetry system, which is accessible both in economic terms and in terms of simplicity of use. In particular the Go Pro Hero3 Black Edition and the Parrot Ar. Drone 2.0 were studied. There are essentially two limitations to the system and they were found for both the instruments used. Indeed, the frames captured by the Go Pro are subject to great distortion and consequently pose numerous calibration problems. On the other hand, the limitation of the system lies in the difficulty of maintaining a flight configuration suitable for photogrammetric purposes in unfavourable environmental conditions. The aim of this research is to analyse how far the limitations highlighted can influence the precision of the survey and consequent quality of the results obtained. To this end, the integrated GoPro and Parrot system was used during a survey campaign on the Altilia archaeological site, in Molise. The data obtained was compared with that gathered by more traditional methods, such as the laser scanner. The system was employed in the field of archaeology because here the question of cost often has a considerable importance and the metric aspect is frequently subordinate to the qualitative and interpretative aspects. Herein one of the products of these systems; the orthophoto will be analysed, which is particularly useful in archaeology, especially in situations such as this dig in which there aren't many structures in elevation present. The system proposed has proven to be an accessible solution for producing an aerial documentation, which adds the excellent quality of the result to metric data for which the precision is known.

    The effect of maternal attitudes and limit-setting strategies on children's self-regulation (measured as committed compliance) was compared in 151 African-American (AA) and 108 European-American (EA) mothers and their 3-year-old children. There were no ethnic differences in children's compliance, however ethnicity moderated the relationship between maternal authoritarian attitudes and children's compliance. Higher authoritarian attitudes predicted less children's compliance in the EA sample, but greater compliance in the AA sample. Observational limit-setting data revealed that in both ethnic groups, maternal authoritarian attitudes influenced children's self-regulation through maternal use of lower-power (gentle) verbal strategies, fewer physical strategies, and judicious use of higher-power verbal strategies. The findings indicate that the meaning and purpose of authoritarian attitudes varies across these mothers' socio-cultural contexts. Copyright © 2011 Wiley Periodicals, Inc.

  13. Forensic anthropology and mortuary archaeology in Lithuania.

    Jankauskas, Rimantas

    2009-12-01

    Forensic anthropology (in Lithuania, as everywhere in Eastern Europe, traditionally considered as a narrower field--forensic osteology) has a long history, experience being gained both during exhumations of mass killings during the Second World War and the subsequent totalitarian regime, investigations of historical mass graves, identification of historical personalities and routine forensic work. Experts of this field (usually a branch of forensic medicine) routinely are solving "technical" questions of crime investigation, particularly identification of (usually dead) individuals. Practical implementation of the mission of forensic anthropology is not an easy task due to interdisciplinary character of the field. On one hand, physical anthropology has in its disposition numerous scientifically tested methods, however, their practical value in particular legal processes is limited. Reasons for these discrepancies can be related both to insufficient understanding of possibilities and limitations of forensic anthropology and archaeology by officials representing legal institutions that perform investigations, and sometimes too "academic" research, that is conducted at anthropological laboratories, when methods developed are not completely relevant to practical needs. Besides of answering to direct questions (number of individuals, sex, age, stature, population affinity, individual traits, evidence of violence), important humanitarian aspects--the individual's right for identity, the right of the relatives to know the fate of their beloved ones--should not be neglected. Practical use of other identification methods faces difficulties of their own (e.g., odontology--lack of regular dental registration system and compatible database). Two examples of forensic anthropological work of mass graves, even when the results were much influenced by the questions raised by investigators, can serve as an illustration of the above-mentioned issues.

  14. Making space for an archaeology of place

    Full Text Available Rather than attempt to write a balanced or complete overview of the application of GIS to archaeology (which would inevitably end up being didactic and uncritical this article sets out to present a discursive and contentious position with the deliberate aim of stimulating further debate about the future role of GIS within our discipline. To this end, existing applications of GIS to archaeology are reviewed, concentrating on two areas of application, predictive modelling and visibility analyses, and on their wider disciplinary context. It is argued that GIS cannot be simplistically held to have been a 'good thing' or a 'bad thing' for archaeology, but rather that these different application areas may be analysed separately and found to have quite different qualities. Although they are in no sense alternatives to one another, the areas of predictive modelling and visibility analysis can be seen to represent quite different agendas for the development of an archaeology of space and/or place. The development of correlative predictive models is considered first, both from the perspective of explanation and of cultural resource management. The arguments against predictive modelling as a means of explanation are rehearsed and it is found to be over-generalising, deterministic and de-humanised. As a consequence, it is argued that predictive modelling is now essentially detached from contemporary theoretical archaeological concerns. Moreover, it is argued to be an area with significant unresolved methodological problems and, far more seriously, that it presents very real dangers for the future representativity of archaeological records. Second, the development of GIS-based visibility analysis is reviewed. This is also found to be methodologically problematic and incomplete. However, it is argued that visibility studies — in direct contrast to predictive modelling — have remained firmly situated within contemporary theoretical debates, notably about

    Full Text Available Social life is produced. Social life takes place before the fact of thinking about it. Drawing upon elements coming from utopian Socialism. British economy and, especially, Hegel’s philosophy, Marx proposed a set of dialectic categories addressed to thinking and to explaining how social life is produced, including in these dynamics the production of ourselves. In this paper, the guidelines of Marx’ thoughts are shown starting from the reading and analysis of his own texts. Also, the pertinence of the relationship between Marx and the research of society is argued through the material objects which make any society real: the archaeological research.

    Research suggests that higher levels of authoritarian parenting exist in African American (AA) families than in European American (EA) families, and that authoritarian attitudes may be associated with more positive outcomes in AA families than EA families. However, less is known about authoritarian attitudes and children's development within AA families. This within-group study of 50 African American mothers and their 3-year-old children examined associations between maternal authoritarian attitudes, observed maternal limit-setting strategies, and children's self-regulation during a limit-setting interaction. The findings indicate that while AA families may hold more authoritarian attitudes than EA families, the direction of effect of authoritarian attitudes on children's outcomes appears to be the same in both ethnic groups. In this sample, when examining AA authoritarian attitudes relative to those of other AA mothers, less or lower authoritarian attitudes were associated with authoritative limit-setting behavior (firm limits within the context of overall warmth and responsiveness) and better children's self-regulation.

    2008-05-01

    In efforts to rehabilitate regulated rivers for ecological benefits, the flow regime has been one of the primary focal points of management strategies. However, channel engineering can impact channel geometry such that hydraulic and geomorphic responses to flow reregulation do not yield the sought for benefits. To illustrate and assess the impacts of structural channel controls and flow reregulation on channel processes and fish habitat quality in multiple life stages, a highly detailed digital elevation model was collected and analyzed for a river reach right below a dam using a suite of hydrologic, hydraulic, geomorphic, and ecological methods. Results showed that, despite flow reregulation to produce a scaled-down natural hydrograph, anthropogenic boundary controls have severely altered geomorphic processes associated with geomorphic self-sustainability and instream habitat availability in the case study. Given the similarity of this stream to many others, we concluded that the potential utility of natural flow regime reinstatement in regulated gravel-bed rivers is conditional on concomitant channel rehabilitation.

    2015-04-01

    Many of the activities of prehistoric people who lived in Taiwan were concentrated around river terrace environments and seldom in alluvial environments which are resulting from the rapid tectonic uplift and high erosion rate of the late Cenozoic mountain belt. However, the Peinan archaeological site, one of the most important Neolithic sites in Taiwan because of the great amount of slate slab coffins and nephrite artifacts unearthed, is located at the bottom of Peinan Hill which is formed by the activity of Lichi and Luyeh Faults. According to the radioactive carbon dating results, the Peinan alluvial fan used as cemetery was lasted over 3,700 years (5700-2000 yr BP) but the related cultural formation was only lasted 400 years (3500-3100 yr BP). What have happened to the prehistoric people? As the stratigraphic record allows archaeologists to ascertain the effects of geological processes on the preservation of the archaeological record, determining which parts of the archaeological records are absent, which have potentially been preserved, and how fragmentary are the preserved portions of the records. The limitations that geologic processes impose on the archaeological record must be recognized and understood before meaningful interpretations of prehistory can be made. Therefore, the reconstruction of the landscape and stratigraphic records in archaeological site not only provides the paleo-environmental context but also helps to explain changes that occurred to human cultures over time.

  2. Extracting Archaeological Feautres from GPR Surveys Conducted with Variable Soil Moisture Conditions

    As a common tool for subsurface archaeological prospection, ground penetrating radar (GPR) is a useful method for increasing the efficiency of archaeological excavations. Archaeological sites are often temporally and financially constrained, therefore having limited ability to reschedule surveys compromised by weather. Furthermore, electromagnetic GPR surveys are especially sensitive to variations in water content, soil type, and site-specific interference. In this work, GPR scans of a partially excavated Roman villa consisting of different construction materials and phases (limestone, andesite, brick) in central Romania are compared. Surveys were conducted with a 500 MHz GPR antenna in both dry (pre-rain event) and wet (post-rain event) conditions. Especially in time or depth slices, wet surveys present additional archaeological features that are not present or clear in the standard dry conditions, while simultaneously masking the clutter present in those scans. When dry, the limestone has a similar dielectric constant to the soil and does not provide enough contrast in electromagnetic properties for strong reflections despite the significant difference in their physical properties. Following precipitation, however, the electromagnetic properties of these two materials is dominated by their respective water content and the contrast is enhanced. For this reason, the wet surveys are particularly necessary for revealing reflections from the limestone features often invisible in dry surveys. GPR surveys conducted in variable environmental conditions provide unique archaeological information, with potential near-surface geophysical applications in nondestructive material characterization and identification.

  3. ARCTIS — A MATLAB® Toolbox for Archaeological Imaging Spectroscopy

    2014-09-01

    Full Text Available Imaging spectroscopy acquires imagery in hundreds or more narrow contiguous spectral bands. This offers unprecedented information for archaeological research. To extract the maximum of useful archaeological information from it, however, a number of problems have to be solved. Major problems relate to data redundancy and the visualization of the large amount of data. This makes data mining approaches necessary, as well as efficient data visualization tools. Additional problems relate to data quality. Indeed, the upwelling electromagnetic radiation is recorded in small spectral bands that are only about ten nanometers wide. The signal received by the sensor is, thus quite low compared to sensor noise and possible atmospheric perturbations. The often small, instantaneous field of view (IFOV—essential for archaeologically relevant imaging spectrometer datasets—further limits the useful signal stemming from the ground. The combination of both effects makes radiometric smoothing techniques mandatory. The present study details the functionality of a MATLAB®-based toolbox, called ARCTIS (ARChaeological Toolbox for Imaging Spectroscopy, for filtering, enhancing, analyzing, and visualizing imaging spectrometer datasets. The toolbox addresses the above-mentioned problems. Its Graphical User Interface (GUI is designed to allow non-experts in remote sensing to extract a wealth of information from imaging spectroscopy for archaeological research.

    The research is an analysis of the recording, reconstruction and visualisation of the 3D data of a XVIII century watermill, identified in an emergency archaeological excavation during the construction of the mini-hydroelectric plant on the bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy). The work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage aimed to increase the research, maintenance and presentation with interactive products. The use of three-dimensional models managed through AR (Augmented Reality) and VR (Virtual Reality) technologies with mobile devices gives several opportunities in the field of study and communication. It also improves on-site exploration of the landscape, enhancing the "minor" archaeological sites, daily subjected to numerous emergency works and facilitating the understanding of heritage sites.

  6. Comparison of German and international clearance regulations - chances and limits for harmonization

    2005-01-01

    The regulations on clearance in the German nuclear regulatory framework (especially sect. 29 and Annexes III and IV of the Radiation Protection Ordinance) are comprehensive and well founded. Germany has developed some of its clearance levels in advance of recommendations issued by the EC. Therefore, there are differences between the German and international clearance regulations. That has been investigated by a working group on clearance of the German Commission on Radiological Protection (SSK) which has performed an analysis of differences and their reasons for clearance levels in Germany and other countries (UK, The Netherlands, Sweden, USA and others). Differences can mainly be explained by country specific approaches in scenarios. Differences especially for the most relevant nuclides are not significant from a radiological point of view. The level of radiological protection (trivial dose range, a few 10 μSv/a) is guaranteed in all countries. The international discussion on the international harmonisation of clearance levels (mainly within the scope of the OECD/NEA and IAEA) can be enlightened on the basis of these results. This discussion concentrates on the question how far a harmonisation of clearance level values is actually necessary and possible. The IAEA Safety Guide RS-G-1.7 'Application of the concepts of exclusion, exemption and clearance' is of particular importance, because it proposes a set of values which might in the long-term take the role of international unconditional clearance levels. International harmonisation is only relevant for unconditional clearance of those materials, which are traded in large quantities among countries, in particular metal scrap. Harmonisation of the values to the same order of magnitude is sufficient. (orig.)

  7. Concentrations of antibiotics predicted to select for resistant bacteria: Proposed limits for environmental regulation.

    Science.gov (United States)

    Bengtsson-Palme, Johan; Larsson, D G Joakim

    2016-01-01

    There are concerns that selection pressure from antibiotics in the environment may accelerate the evolution and dissemination of antibiotic-resistant pathogens. Nevertheless, there is currently no regulatory system that takes such risks into account. In part, this is due to limited knowledge of environmental concentrations that might exert selection for resistant bacteria. To experimentally determine minimal selective concentrations in complex microbial ecosystems for all antibiotics would involve considerable effort. In this work, our aim was to estimate upper boundaries for selective concentrations for all common antibiotics, based on the assumption that selective concentrations a priori need to be lower than those completely inhibiting growth. Data on Minimal Inhibitory Concentrations (MICs) were obtained for 111 antibiotics from the public EUCAST database. The 1% lowest observed MICs were identified, and to compensate for limited species coverage, predicted lowest MICs adjusted for the number of tested species were extrapolated through modeling. Predicted No Effect Concentrations (PNECs) for resistance selection were then assessed using an assessment factor of 10 to account for differences between MICs and minimal selective concentrations. The resulting PNECs ranged from 8 ng/L to 64 μg/L. Furthermore, the link between taxonomic similarity between species and lowest MIC was weak. This work provides estimated upper boundaries for selective concentrations (lowest MICs) and PNECs for resistance selection for all common antibiotics. In most cases, PNECs for selection of resistance were below available PNECs for ecotoxicological effects. The generated PNECs can guide implementation of compound-specific emission limits that take into account risks for resistance promotion. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    Eldorado Nuclear Limited's operations at Port Hope, Ontario include both chemical and metallurgical processes involved in processing uranium in various forms. The plant processes natural uranium for both the domestic and export markets, and processes enriched uranium for the fuel in Canada's research reactors and for booster fuel for Candu reactors. The plant receives wastes from fuel fabrication plants and recycles them to recover uranium, and also produces wastes of its own. The Atomic Energy Control Board (AECB) is involved at all stages of this operation, as the agency responsible for nuclear materials management, safeguards, occupational health and safety, and safe disposal of wastes in all Canada's nuclear facilities. The AECB has also been involved in the clean up of contamination from the early days of operations in Port Hope

  15. Robust Nonlinear Regulation of Limit Cycle Oscillations in UAVs Using Synthetic Jet Actuators

    Directory of Open Access Journals (Sweden)

    Natalie Ramos Pedroza

    2014-09-01

    Full Text Available In this paper, a synthetic jet actuators (SJA-based nonlinear robust controller is developed, which is capable of completely suppressing limit cycle oscillations (LCO in UAV systems with parametric uncertainty in the SJA dynamics and unmodeled external disturbances. Specifically, the control law compensates for uncertainty in an input gain matrix, which results from the unknown airflow dynamics generated by the SJA. Challenges in the control design include compensation for input-multiplicative parametric uncertainty in the actuator dynamic model. The result was achieved via innovative algebraic manipulation in the error system development, along with a Lyapunov-based robust control law. A rigorous Lyapunov-based stability analysis is utilized to prove asymptotic LCO suppression, considering a detailed dynamic model of the pitching and plunging dynamics. Numerical simulation results are provided to demonstrate the robustness and practical performance of the proposed control law.

    Duty hour regulations have been placed in residency programs to address mental health concerns and to improve wellness. Here, we elucidate the prevalence of depressive symptoms after implementing an overnight call shift system and the factors associated with burnout or depression among residents.A sequential exploratory mixed methods study was conducted in a tertiary care pediatric and perinatal hospital in Tokyo, Japan. A total of 41 pediatric residents participated in the cross-sectional survey. We determined and compared the prevalence of depressive symptoms and the number of actual working hours before and after implementing the shift system. A follow-up focus-group interview with 4 residents was conducted to explore the factors that may trigger or prevent depression and burnout.Mean working hours significantly decreased from 75.2 hours to 64.9 hours per week. Prevalence of depressive symptoms remained similar before and after implementation of the shift system. Emotional exhaustion and depersonalization from the burnout scale were markedly associated with depression. High workload, stress intolerance, interpersonal difficulties, and generation gaps regarding work-life balance could cause burnout. Stress tolerance, workload monitoring and balancing, appropriate supervision, and peer support could prevent burnout.Although the overnight call shift system was effective in reducing working hours, its effectiveness in managing mental health issues among pediatric residents remains unclear. Resident wellness programs represent an additional strategy and they should be aimed at fostering peer support and improvement of resident-faculty interactions. Such an approach could be beneficial to the relationship between physicians of different generations with conflicting belief structures.

  17. Vasoinhibins regulate the inner and outer blood-retinal barrier and limit retinal oxidative stress.

    Vasoinhibins are prolactin fragments present in the retina, where they have been shown to prevent the hypervasopermeability associated with diabetes. Enhanced bradykinin (BK) production contributes to the increased transport through the blood-retina barrier (BRB) in diabetes. Here, we studied if vasoinhibins regulate BRB permeability by targeting the vascular endothelium and retinal pigment epithelium (RPE) components of this barrier. Intravitreal injection of BK in male rats increased BRB permeability. Vasoinhibins prevented this effect, as did the B2 receptor antagonist Hoe-140. BK induced a transient decrease in mouse retinal and brain capillary endothelial monolayer resistance that was blocked by vasoinhibins. Both vasoinhibins and the nitric oxide (NO) synthase inhibitor L-NAME, but not the antioxidant N-acetyl cysteine (NAC), blocked the transient decrease in bovine umbilical vein endothelial cell (BUVEC) monolayer resistance induced by BK; this block was reversed by the NO donor DETANONOate. Vasoinhibins also prevented the BK-induced actin cytoskeleton redistribution, as did L-NAME. BK transiently decreased human RPE (ARPE-19) cell monolayer resistance, and this effect was blocked by vasoinhibins, L-NAME, and NAC. DETANONOate reverted the blocking effect of vasoinhibins. Similar to BK, the radical initiator Luperox induced a reduction in ARPE-19 cell monolayer resistance, which was prevented by vasoinhibins. These effects on RPE resistance coincided with actin cytoskeleton redistribution. Intravitreal injection of vasoinhibins reduced the levels of reactive oxygen species (ROS) in retinas of streptozotocin-induced diabetic rats, particularly in the RPE and capillary-containing layers. Thus, vasoinhibins reduce BRB permeability by targeting both its main inner and outer components through NO- and ROS-dependent pathways, offering potential treatment strategies against diabetic retinopathies.

    Key Findings. The Patient Protection and Affordable Care Act (ACA) is designed to offer premium subsidies to help eligible individuals and their families purchase insurance coverage when affordable job-based coverage is not available. However, the law is unclear on how this affordability protection is applied in those instances where self-only coverage offered by an employer is affordable but family coverage is not. Regulations recently proposed by the Department of the Treasury would make family members ineligible for subsidized coverage in the exchange if an employee is offered affordable self-only coverage by an employer, even if family coverage is unaffordable. This could have significant financial consequences for low- and moderate-income families that fall in this gap. Using an alternative interpretation of the law could allow the entire family to enter the exchange when family coverage is unaffordable, which would broaden access to coverage. However, this option has been cited as cost prohibitive. In this brief we consider a middle ground alternative that would base eligibility for the individual worker on the cost of self-only coverage, but would use the additional cost to the employee for family coverage as the basis for determining affordability and eligibility for subsidies for the remaining family members. We find that: Under the middle ground alternative scenario an additional 144,000 Californians would qualify for and use premium subsidies in the California Health Benefit Exchange, half of whom are children. Less than 1 percent of those with employer-based coverage would move to subsidized coverage in the California Health Benefit Exchange as a result of having unaffordable coverage on the job.

    Full Text Available Vasoinhibins are prolactin fragments present in the retina, where they have been shown to prevent the hypervasopermeability associated with diabetes. Enhanced bradykinin (BK production contributes to the increased transport through the blood-retina barrier (BRB in diabetes. Here, we studied if vasoinhibins regulate BRB permeability by targeting the vascular endothelium and retinal pigment epithelium (RPE components of this barrier. Intravitreal injection of BK in male rats increased BRB permeability. Vasoinhibins prevented this effect, as did the B2 receptor antagonist Hoe-140. BK induced a transient decrease in mouse retinal and brain capillary endothelial monolayer resistance that was blocked by vasoinhibins. Both vasoinhibins and the nitric oxide (NO synthase inhibitor L-NAME, but not the antioxidant N-acetyl cysteine (NAC, blocked the transient decrease in bovine umbilical vein endothelial cell (BUVEC monolayer resistance induced by BK; this block was reversed by the NO donor DETANONOate. Vasoinhibins also prevented the BK-induced actin cytoskeleton redistribution, as did L-NAME. BK transiently decreased human RPE (ARPE-19 cell monolayer resistance, and this effect was blocked by vasoinhibins, L-NAME, and NAC. DETANONOate reverted the blocking effect of vasoinhibins. Similar to BK, the radical initiator Luperox induced a reduction in ARPE-19 cell monolayer resistance, which was prevented by vasoinhibins. These effects on RPE resistance coincided with actin cytoskeleton redistribution. Intravitreal injection of vasoinhibins reduced the levels of reactive oxygen species (ROS in retinas of streptozotocin-induced diabetic rats, particularly in the RPE and capillary-containing layers. Thus, vasoinhibins reduce BRB permeability by targeting both its main inner and outer components through NO- and ROS-dependent pathways, offering potential treatment strategies against diabetic retinopathies.

    The present work shows the results of the preparation of archaeological samples for their dating by thermoluminescence (Tl) using the Fine grain technique established by Zimmerman but with the varying of such preparation was realized in normal daylight conditions, only the taking of the Tl readings were realized in dark room and red light. In the chapter 1 basic concepts are described about: matter constitution, radioactivity, units and radiation magnitudes, and thermoluminescence. In the chapter 2 some theoretical aspects on dating are showed. It is described how realizing the samples collection, the fine grain method, the determination of the accumulated dose through the years or paleodoses (P=Q+I) by mean of the increasing to obtain the dose equivalent dose (Q) and the signal regeneration method to obtain the correction factor by supra linearity (1), the determination of the annual dose rate to apply the age equation and the evaluation of the age uncertainty with the error limits. The development of experimental part with samples from the archaeological site named Edzna in Campeche, Mexico is described in the chapter 3. The results are presented in the chapter 4. It was obtained an age for the sample named CH7 it was obtained an age of 389 ± years. In conclusion the preparation of the archaeological samples for their dating by Tl in the conditions before mentioned is reliable, but they must be realized more studies with samples of well known age, preparing them in normal daylight conditions and simultaneously in dark room with red light. In order to observe how respond the minerals present in the sample at different dose rapidity, the same samples must be radiated with radiation sources with different dose rate. (Author)

    Full Text Available Reliability of a road is mandatory since damaged will impede the traffic. Destruction is caused by various factors; one of the most important factors is excess load. Overload may give the load of each axle of a vehicle exceeds the determined standard. This condition occurs in trucks exceeding the load limit. In designing the structure of a road based on the method of Directorate General of Highways Ministry of Public Works of the Republic of Indonesia, axle load calculated in equivalent-number, or known as equivalent axle load (EAL, of 8.16 tons of standard axle. Total equivalent-number over the service life is defined as cumulative equivalent standard axle load (CESA. Due to traffic volume exceeding the volume forecast or, in other words there is an excessive load of traffic, it will make CESA achieved faster than planned. This excessive load in Indonesia, however, has been  considered as a factor of environmental condition, so there is a need to introduce a correction factor for EAL as high as 20-25% in the process of designing flexible and rigid pavement so as to reduce early damage.

    2009-01-01

    The reconstruction of the past and the understanding of historical and cultural aspects of societies that developed at archaeological sites have been enabled by archaeometric studies undertaken on ceramics located at these areas. This study aims to be a contribution to the elucidation of these aspects with the application of three physical methods of analysis: neutron activation analysis (NAA), thermoluminescence dating (TL) an electronic paramagnetic resonance (EPR) to ceramic fragments from the Hatahara archaeological site, located at central Amazon. The elemental concentrations obtained by NAA for 120 ceramic fragments were interpreted by means of cluster analysis and discriminant analysis. The results showed the existence of five distinct ceramic groups. This information, supported by archaeological interpretation, confirm the existence of four distinct occupation Phases at Hatahara site. In order to establish a chronology for the occupations, the ages of three ceramic fragments were determined by TL. The dating of two fragments did not confirm the archaeological interpretation about their occupation Phases. However, the dating of the third fragment allowed the confirmation that it belongs to the Manacapuru Phase. The determination of the burning temperatures of four ceramic fragments was performed by EPR. It was observed that although the analyzed ceramic samples belong to three distinct groups, there was no significant variation on their burning temperatures. (author)

  12. What Kind of Archaeology do We Need?

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available From the time of the constitution of archaeology as an academic discipline to the present, two radical changes have taken place of theoretical postulates, aims, methods, relationships with other disciplines. However, potentially farreaching consequences of these fundamental changes have not had the same impact in all the academic communities. The critical assessment of the epistemological foundations of archaeology in Serbia indicates that our professional community has remained resistant to the large extent to the paradigm changes in the wider disciplinary surrounding, so the culture-historical approach still prevails, even though it was severely criticized as early as by the middle of the 20th century. Facing this significant delay raises many important questions, starting by the issue of selection among various, sometimes mutually conflicting theoretical approaches, being a part of archaeological research for several decades and implying certain consequences in terms of methodological aspects of the discipline. Partial, non-critical and insufficiently theoretically informed borrowing of individual elements of research may lead to equally bad results as the total rejection of influences from other archaeological environments. It is therefore necessary to bring into the discipline the comprehension of the social responsibility of archaeologists, the importance of the academic narratives we produce and the ways of their creation.

  15. The suitability of EDXRF for compositional classification of archaeological pottery

    International Nuclear Information System (INIS)

    Padilla Alvarez, Roman

    2007-01-01

    Many investigations have been carried out trying to enlarge the information that can be gathered through the chemical analysis of archaeological findings. Chemical composition data sets, properly interpreted with multivariate analysis techniques, have been used extensively to supplement investigations involving provenance studies or more complex socio-economic aspects of the past communities. Correct inferences from the gathered compositional data are only possible if well documented background information about the studied samples is available, such as a correct interpretation of the archaeological contexts, knowledge about the nature of the used raw materials or procurement sources (geology of the territories), among others. The combined use of Instrumental Neutron Activation Analysis (INAA) and Scanning Electron Microscopy X-ray analysis (SEM-EDX) has been widely applied to the classification of archaeological pottery. However the need to remove at least a minimal part (invasion) of the sample and the time delay required for radioisotope decay and the high costs involved in INAA often restrict its use. Energy Dispersive x-ray Fluorescence spectrometry (EDXRF) is advantageous to perform a completely non-destructive analysis in a relatively fast way, but several problems have restricted its wider use in the past. The highly matrix-dependent attenuation of x-rays in the analysed sample hampers the use of the standard-less quantification procedures as an alternative when suitable certified reference materials are not at hand, and the relatively limited instrumental sensitivity of the conventional spectrometers has not allowed the determination of some trace elements that are relevant for compositional differentiation and provided a comparatively higher uncertainties. This contribution presents the results of several investigations aimed to achieving classification of archaeological pottery using reliable quantitative EDXRF procedures. The main factors affecting the

    Full Text Available Archaeology offers insight into the values of the contemporary world. From three separate discourses, which address different temporalities and sites, an overarching archaeological narrative has been established, which reflects the role of art and heritage in artistic destruction; education and archaeology as an educational and social tool; and materiality (in the present case, the Chinese pottery sherds in Al-Andalus in the interpretations and acts of archaeologists. The visual values of archaeology and the role of the archaeological imagination to unify disparate archaeological practices will be explored here. The permeability of the spheres of archaeology and art allow us to explore both archaeological and artistic practices, as well as reflect on universal convictions and on the potentiality of archaeological practice to intervene in social contexts. With all this, archaeology acquires relevance insofar as it is a practice that is able to address the problems of the present day. In line with the so-called ‘creative archaeologies’, with their experimentation and creation of artistic works (in this case photographic, this paper aims to reflect on new ways to ‘see’ archaeology, which has never been more necessary.

    2017-01-01

    The environmental regulation of hazardous projects with risk-based decision-making processes can lead to a deficient management of human exposure to technological hazards. Such an approach for regulation is criticized for simplifying the complexity of decisions involving the economic, social, and environmental aspects of the installation and operation of hazardous facilities in urban areas. Results of a Brazilian case study indicate that oil and gas transmission pipelines may represent a threat to diverse communities if the relationship between such linear projects and human populations is overlooked by regulatory bodies. Results also corroborate known challenges to the implementation of EIA processes and outline limitations to an effective environmental and risk management. Two preliminary topics are discussed to strengthen similar regulatory practices. Firstly, an effective integration between social impact assessment and risk assessment in EIA processes to have a more comprehensive understanding of the social fabric. Secondly, the advancement of traditional management practices for hazardous installations to pursue a strong transition from assessment and evaluation to management and control and to promote an effective interaction between land-use planning and environmental regulation.

    ABSTRACT In limiting oxygen as an electron acceptor, the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 rapidly forms nanowires, extensions of its outer membrane containing the cytochromes MtrC and OmcA needed for extracellular electron transfer. RNA sequencing (RNA-Seq) analysis was employed to determine differential gene expression over time from triplicate chemostat cultures that were limited for oxygen. We identified 465 genes with decreased expression and 677 genes with increased expression. The coordinated increased expression of heme biosynthesis, cytochrome maturation, and transport pathways indicates that S. oneidensis MR-1 increases cytochrome production, including the transcription of genes encoding MtrA, MtrC, and OmcA, and transports these decaheme cytochromes across the cytoplasmic membrane during electron acceptor limitation and nanowire formation. In contrast, the expression of the mtrA and mtrC homologs mtrF and mtrD either remains unaffected or decreases under these conditions. The ompW gene, encoding a small outer membrane porin, has 40-fold higher expression during oxygen limitation, and it is proposed that OmpW plays a role in cation transport to maintain electrical neutrality during electron transfer. The genes encoding the anaerobic respiration regulator cyclic AMP receptor protein (CRP) and the extracytoplasmic function sigma factor RpoE are among the transcription factor genes with increased expression. RpoE might function by signaling the initial response to oxygen limitation. Our results show that RpoE activates transcription from promoters upstream of mtrC and omcA. The transcriptome and mutant analyses of S. oneidensis MR-1 nanowire production are consistent with independent regulatory mechanisms for extending the outer membrane into tubular structures and for ensuring the electron transfer function of the nanowires. IMPORTANCE Shewanella oneidensis MR-1 has the capacity to transfer electrons to its external surface

    The vast amount of archaeological data and information that is systematically accumulated in the Israel Antiquities Authority database, has not yet been transformed into a tool for heritage management, i.e. accessible knowledge of the sites' cultural significance and risk assessment that is needed to support wise decision making regarding its future. As a response, a pilot project for developing an inventory for the archaeological heritage management was launched. A basic ESRI ArcGIS Online system was developed as a prototype, following the categories recommended in international standards for documentation. Five field surveys implementing the GIS system were conducted to examine different aspects and workflows: ancient synagogues in the Galilee, sites at risk, mosaics in Tel Shiqmona, the ancient settlement of Huqoq and sites included in The National Master Plan for Forests and Afforestation. The pilot project revealed the main gaps in knowledge and the critical faults in the working procedures. In spite of the systems' technological limitations, the results were convincing enough to promote a multidisciplinary discussion about the need for integration of significance and risk assessment in the working processes of the organization.

  1. Saccharomyces cerevisiae Fermentation Effects on Pollen: Archaeological Implications

    Directory of Open Access Journals (Sweden)

    Crystal A. Dozier

    2016-03-01

    Full Text Available Pollen is the reproductive agent of flowering plants; palynology is utilized by archaeologists because sporopollenin, a major component in the exine of pollen grains, is resistant to decay and morphologically distinctive. Wine, beer, and mead have been identified in the archaeological record by palynological assessment due to indicator species or due to a pollen profile similar to that recovered from honey, a common source of sugar in a variety of fermented beverages. While most palynologists have assumed that pollen grains are resistant to alcoholic fermentation, a recent study in food science implies that pollen is a yeast nutrient because pollen-enriched meads produce more alcohol. The experiment presented here explores the potential distortion of the pollen record through fermentation by brewing a traditional, pollen-rich mead with Saccharomyces cerevisiae. In this experiment, the pollen grains did not undergo any discernible morphological changes nor were distorted in the pollen profile. Any nutrition that the yeast garners from the pollen therefore leaves sporopollenin intact. These results support palynological research on residues of alcoholic beverages and confirms that the fermentation process does not distort the pollen profile of the original substance. The paper concludes with the potential and limits of palynological study to assess fermentation within the archaeological record.

    2017-06-01

    This paper is an overview of recent developments in the radiocarbon dating of the most frequently analyzed archaeological materials - wood, short-lived plants, and human and animal bones - and draws attention to two sets of consequences. Firstly, while radiocarbon dating has become more accessible to archaeologists thanks to an increase in the number of laboratories, a lowering of prices, and a reduction in sample sizes, it has also grown far more dependent on fields of research, other than the traditional chemical pretreatment of samples and the physics involved in their measurement, such as wood anatomy and other fields of botany, stable isotope-based diet studies, geochemistry, micromorphology, statistics, etc., most of which are not easily accessible by the vast majority of users of radiocarbon dating (and sometimes not familiar to practicing archaeologists). Secondly, given that, on the one hand, there is still much scope for research in radiocarbon dating and, on the other, archaeological sites are a limited resource, there is need to create archives containing the detailed documentation of samples and, whenever possible, sample residues.

    The aim of present research is to obtain information about archaeological analogous of iron and steel, useful for the model of deep geological repository (AGP). The analogous examined have remained buried between 1400 and 2400 years, in very assorted geochemical environments. The extraction of the archaeological pieces has been accomplished according to normalised protocols, trying to carry to the laboratory so the piece as its burial environment, avoiding all possible pollution. Trying to the archaeological analogous could provide valuable information to the AGP model, the study has been directed to related the physical-chemical characteristics of the terrain respect to the deterioration of the archaeological metallic piece. The geology of the surrounding terrain to the archaeological deposit, the geomorphological study of the terrain and data from the analysis of ground: pH, wetness, porosity, organic matter contents, bacteria presence, sulphates, carbonates, chlorides, etc., have allowed to explain the physical-chemical phenomena suffered by the archaeological iron and steel pieces. Also, an exhaustive study of the archaeological piece has been accomplished, concerning the microstructure of the corrosion layer and of the not deteriorated metallic rest. Obtained information concerns different items, such as corrosion velocity and formations of oxide layers, diffusion of chemical elements from the corrosion layer to the metal and viceversa, and structural changes in oxide layers and in the metallic remains by structural ageing. Obtained data have allowed to develop a mathematical model for calculation of corrosion velocity in buried iron and steels, based on physical-chemical variables of grounds, chemical composition and thermomechanical treatment given to the metal during its manufacture.

    Full text: Precious stones have been attractive pieces of jewelry since ancient times. However, due to the limited sources of origin, the quality of applied items mainly depended on long-range commercial relations, but also on fashion. In Antiquity and Late Antiquity, stones much used and sought for were emeralds and garnets. In Slovenia, emeralds are typically related to the early Roman period and are incorporated in the finds of gold jewelry from the graves. Emerald is generally beryl colored by admixture of chromium, though green colors can also be due to admixtures of iron or vanadium. Garnets were increasingly used by various nations of the People Migration period, and mounted in gilded silver or gold objects by 'cloisonne' or 'en cabochon' techniques. In Slovenia, numerous jewelry items containing garnets were found in the graves and in post-Roman fortified settlements. Geologically, according to the admixtures of metal ions, the garnets are divided into several species, while the most common among archaeological finds are almandines and pyropes and their intermediate types. It is also common to divide garnets into five groups, the first two originating from India, the third from Ceylon and the fifth from Czech Republic. The measurements involved presumed emeralds from Roman jewelry finds in Slovenia and comparative samples of beryl from Siberia and Habachtal in Austria. The analysis determined the coloring ions and showed relations between particular stones. For garnets, ten samples from brooches, earrings and rings were selected for the analysis on the basis of previous micro Raman examination. The analysis was performed by a combined PIXE-PIGE technique using proton beam in air. The light elements of Na, Mg, AI were determined according to the emitted gamma rays, while X-rays were used for the elements heavier than silicon.

Garnets were increasingly used by various nations of the People Migration period, and mounted in gilded silver or gold objects by 'cloisonne' or 'en cabochon' techniques. In Slovenia, numerous jewelry items containing garnets were found in the graves and in post-Roman fortified settlements. Geologically, according to the admixtures of metal ions, the garnets are divided into several species, while the most common among archaeological finds are almandines and pyropes and their intermediate types. It is also common to divide garnets into five groups, the first two originating from India, the third from Ceylon and the fifth from Czech Republic. The measurements involved presumed emeralds from Roman jewelry finds in Slovenia and comparative samples of beryl from Siberia and Habachtal in Austria. The analysis determined the coloring ions and showed relations between particular stones. For garnets, ten samples from brooches, earrings and rings were selected for the analysis on the basis of previous micro Raman examination. The analysis was performed by a combined PIXE-PIGE technique using proton beam in air. The light elements of Na, Mg, AI were determined according to the emitted gamma rays, while X-rays were used for the elements heavier than silicon. Two X-ray spectra were measured in each measuring point, soft and hard X-ray; the latter was obtained using an

    Full Text Available Basic stages of Kazan archaeological school development are traced from its origin, which was connected to the Society of Archaeology, History and Ethnology with Kazan University (1878 – early 1930s. The establishment of Kazan Institute of Language, Literature and History in 1939 (from 1945 as part of Kazan Branch of the USSR Academy of Sciences started the formation of Kazan archaeological school. At the beginning, its representatives worked in the sector of History, Institute of Language, Literature and History, Kazan branch of the USSR Academy of Sciences (until 1962, and then joined the sector of Archaeology and Ethnography (1962–1986. Later on, the Department of Archaeology (1986–1995 was created, subsequently (in 1995 transformed into the National Center of Archaeological Research with the Institute of History named after Sh. Marjani of Tatarstan Academy of Sciences. In July, 2013, the Institute of Archaeology named after A.Kh. Khalikov of Tatarstan Academy of Sciences was established on the basis of the Center. The archaeology of Tatarstan was developing in the framework of three basic directions: 1 entire investigation prospecting of the region aimed at creating the most exhaustive list of archaeological monuments of the Middle Volga River region; 2 stationary investigations the prehistoric and medieval sites, first of all historically known Volga Bulgaria towns, rural settlements and necropolises; 3 studies in the sphere of ethnogenesis and ethnic history, interaction between the cultures of the Turkic and Finno-Ugric peoples of the region. For the next 5 years (2014–2018 the researchers of the Institute plan to develop the following trends: I. the medieval Turkic-Tatar civilization of Eurasia; II. prehistorical archaeology of the Volga-Kama region: genesis and interaction of cultures; III. GIS technologies in archaeology; IV. natural science research methods in archaeology; V. conservation and systematization of archaeological

    2015-09-01

    Full Text Available Theoretical and methodological problems of creation the glossary for the preparation of encyclopedic dictionary, which is related to the Republic of Tatarstan archaeology are considered in this article. It is noticed that creation of such generalizing editions determines a new important stage of science and its theoretic and methodological basis development. Encyclopedias and dictionaries are the terminological thesaurus and functioning as a source of norms. They are forming the uniform, unifying and conventional approach to archaeological definitions and their content. They are also able to provide an insight into the basic archaeological concepts in the accessible form, to give the characteristic to archaeological monuments on Republic territory, to acquaint with archaeologists, who has ever worked on territory of Tatarstan, to present the last archaeological discoveries, and to popularize achievements of the Kazan Archaeology school. The complete information about archaeology in Republic is supposed to be included in the encyclopedic dictionary on archaeology of Tatarstan (the special attention will be focused on the conceptual system of archaeology, monuments and antiquity subjects, about objects and monuments of historic and archaeological heritage, as well as biographic data of all archaeologists who has ever worked in Tatarstan and information about all organizations related to archaeology in region. There are all preconditions to claim that the considerable source study and theoretical base for creation of the encyclopedic dictionary on archaeology of Tatarstan is created. It is gathered the significant experience on complex studying and generalization of considerable volume of a material which is referring to an ancient and medieval history of region and on research and ordering of archaeological monuments. It is suggested that at the first investigation phase will be created a glossary and after that the collective of authors can pass

    Retinal degeneration is characterized by the progressive destruction of retinal cells, causing the deterioration and eventual loss of vision. We explored whether the hormone prolactin provides trophic support to retinal cells, thus protecting the retina from degenerative pressure. Inducing hyperprolactinemia limited photoreceptor apoptosis, gliosis, and changes in neurotrophin expression, and it preserved the photoresponse in the phototoxicity model of retinal degeneration, in which continuous exposure of rats to bright light leads to retinal cell death and retinal dysfunction. In this model, the expression levels of prolactin receptors in the retina were upregulated. Moreover, retinas from prolactin receptor-deficient mice exhibited photoresponsive dysfunction and gliosis that correlated with decreased levels of retinal bFGF, GDNF, and BDNF. Collectively, these data unveiled prolactin as a retinal trophic factor that may regulate glial-neuronal cell interactions and is a potential therapeutic molecule against retinal degeneration.

  10. CYLD Limits Lys63- and Met1-Linked Ubiquitin at Receptor Complexes to Regulate Innate Immune Signaling

    Directory of Open Access Journals (Sweden)

    Matous Hrdinka

    2016-03-01

    Full Text Available Innate immune signaling relies on the deposition of non-degradative polyubiquitin at receptor-signaling complexes, but how these ubiquitin modifications are regulated by deubiquitinases remains incompletely understood. Met1-linked ubiquitin (Met1-Ub is assembled by the linear ubiquitin assembly complex (LUBAC, and this is counteracted by the Met1-Ub-specific deubiquitinase OTULIN, which binds to the catalytic LUBAC subunit HOIP. In this study, we report that HOIP also interacts with the deubiquitinase CYLD but that CYLD does not regulate ubiquitination of LUBAC components. Instead, CYLD limits extension of Lys63-Ub and Met1-Ub conjugated to RIPK2 to restrict signaling and cytokine production. Accordingly, Met1-Ub and Lys63-Ub were individually required for productive NOD2 signaling. Our study thus suggests that LUBAC, through its associated deubiquitinases, coordinates the deposition of not only Met1-Ub but also Lys63-Ub to ensure an appropriate response to innate immune receptor activation.

  12. WATER AND ARCHAEOLOGY FOR SUSTAINABLE TOURISM

    Directory of Open Access Journals (Sweden)

    NICHOLAS KATHIJOTES

    2016-03-01

    Full Text Available Water is undoubtedly the most precious resource of the planet and the accessibility to water resources marked the history of mankind since the dawn of times. Water has been indeed very central to archaeology and anthropology, that studied the ways in which water was provisioned, tanked, distributed, worshipped, exploited for agricultural irrigation or to power machines like water-mills, used for leisure, hygiene and healing, or abused to confer power on particular groups ,and how it played a central role in political and economic strategies. More than any other factor, waterways marked cultural and economic developments in history. This paper outlines examples of water resources management throughout the ages, in Cyprus and the Hellenic Civilization on different aspects of the use and management of water, investigates technical issues and gives suggestions, thus promoting a new approach to archaeological heritage and sustainable tourism.

    Iron surface concentrations and profile maps were measured on the enamel of archaeological and modern teeth to determine how iron is deposited in tooth enamel and if it was affected by the post-mortem environment. Teeth from Australian children who died in the second half of the 19th century were compared with contemporary teeth extracted for orthodontic purposes. Surface analysis of the teeth was performed using the 3 MV Van Der Graff Accelerator at The Australian Nuclear Science and Technology Organisation (ANSTO), Sydney, Australia. A small sample of teeth were then cut in the mid sagittal plane and analysed using ANSTO High Energy Heavy Ion Microprobe. Maps and linear profiles were produced showing the distribution of iron across the enamel. Results show that both the levels and distribution of iron in archaeological teeth is quite different to contemporary teeth, raising the suggestion that iron has been significantly altered by the post-mortem environment.

  20. Contextualising Archaeological Information Through Interactive Maps

    Directory of Open Access Journals (Sweden)

    Ian Johnson

    2002-09-01

    Full Text Available Many web sites use maps delivered as non-interactive images. With the development of web-enabled mapping, new methods of presenting and contextualising archaeological and historical data are becoming available. However, most current examples are static views of contemporary framework data or specific time slices, and do not provide interactivity relating to the time dimension, which is so important to archaeology and related disciplines. In this article I look at some of the advantages of time-enabled interactive mapping and map animation in providing educational experiences to museum visitors and the web-browsing public. These will be illustrated through three example applications of the TimeMap methodology developed at the University of Sydney Archaeological Computing Laboratory: 1. the Sydney TimeMap kiosk at the Museum of Sydney; 2. an embedded Java mapping applet developed for MacquarieNet, a major Australian online educational encyclopaedia; and 3. the metadata clearinghouse mapping applet developed for the Electronic Cultural Atlas Initiative, Berkeley. In each of these examples, a wide range of resources are delivered through a time-enabled map interface which accesses live database data rather than pre-structured curated presentations of data. This flexibility brings its own challenges in providing intuitive pathways and appropriate levels of detail in response to free-ranging user enquiries. The paper outlines some of the approaches I have adopted to resolve these issues.

  1. TOF neutron diffraction study of archaeological ceramics

    Kockelmann, W.; Kirfel, A.

    1999-01-01

    Complete text of publication follows. The time-of flight (TOF) neutron diffractometer ROTAX [1] at ISIS has been used for identification and quantitative phase analysis of archaeological pottery. Neutron diffraction yields mineral phase fractions which, in parallel with information obtained from other archaeometric examination techniques, can provide a fingerprint that can be used to identify provenance and reconstruct methods of manufacturing of an archaeological ceramic product. Phase fractions obtained from a 13th century Rhenish stoneware jar compare well with those obtained from a powder sample prepared from the same fragment. This indicates that reliable results can be obtained by illuminating a large piece or even an intact ceramic object making TOF neutron diffraction a truly non-destructive examination technique. In comparison to X-ray diffraction, information from the bulk sample rather than from surface regions is obtained. ROTAX allows for a simple experimental set-up, free of sample movements. Programmes of archaeological study on ROTAX involve Russian samples (Upper-Volga culture, 5000-2000 BC), Greek pottery, (Agora/Athens, 500-300 BC), and medieval German earthenware and stoneware ceramics (Siegburg waster heap, 13-15th century).

  2. Basic Issues in Harappan Archaeology: Some Thoughts

    Directory of Open Access Journals (Sweden)

    Vasant Shinde

    2006-12-01

    Full Text Available The identification of the Harappan Civilization in the early twentieth century was considered to be the most significant archaeological discovery in the Indian Subcontinent as it pushed the beginning of settled life by 2000 years. Contemporary to the Mesopotamian and Egyptian Civilizations it was unique in its town planning. Spread over major parts of the western and north-western subcontinent, its influence is seen to the Tajikistan border in the north and the Gulf region in the west with over two thousand sites found till date. The past eight decades of research have brought to light many important details of the culture including the cultural process involving its origin, maturity and decline but certain aspects such as the terminology, climatic influence, regional variations, script etc are still very flimsy. To gain more information the focus of research will have to shift from Mega Site Archaeology to Small Site Archaeology with large multidisciplinary research projects to acquire a more holistic picture of the Harappan culture.

    The ubiquitous presence of iron minerals within the soils and sediments forming archaeological sites can often provide a valuable record of past human activity. These records are formed through the alteration of weakly magnetic minerals to fine grained iron oxides, such as magnetite or maghaemite, that leave an almost indelible magnetic 'finger print' on the landscape. Archaeologists have exploited these magnetic records at a variety of levels from geophysical survey to reveal the location of a site, to determining how old a particular excavated feature may be through archaeomagnetic dating. More recent studies have investigated the process of magnetic enhancement through the often complex interaction of pedogenic, microbial and anthropogenic mechanisms and pathways. This research has revealed many unique magnetic signatures within archaeological sediments that may help to identify a range of significant environmental conditions, such as the effects of climate change or the deliberate use of fire. This paper aims to provide an overview of how the techniques of environmental magnetism may be applied to the analysis of archaeological remains. Both field based geophysical prospecting and the measurement of magnetic properties from samples recovered during excavation will be considered. The interpretation of the resulting magnetic measurements will also be addressed through the use of an unmixing algorithm applied to hysteresis data.

    2011-06-01

    Full Text Available The archaeology and history of the Republic of Azerbaijan is not widely known in comparison with that of its neighbours. A recent summary of work in the Caucasus (Smith and Rubinson 2003 contained no specific references to results from Azerbaijan, although the studies were directly comparable and overlapped in period and geography. The reasons for this are many, perhaps the most influential is the presentation of material from Azerbaijan being confused with southern Azerbaijan in Iran in the wider academic audience and the use of the Cyrillic alphabet for reports written in the Azeri language over the past century. The Baku-Tbilisi-Ceyhan (BTC and South Caucasus Pipelines (SCP were constructed through Azerbaijan, Georgia and Turkey during the period 2003-5. BTC was built first from the Caspian Coast to the Georgian border during 2003 and 2004, while the SCP pipeline was built from the Georgian border towards the Caspian and parallel to the BTC in 2005. To investigate and mitigate the effects of this construction, a four year archaeological fieldwork programme (2001-2005 was carried out, followed by a further six-year post-excavation programme that ended in early 2011. This article draws on this extensive archaeological project that combines both the broad corpus of material known in Azerbaijan and new techniques introduced in the Republic for the first time and used on a range of sites that are of both national and international significance.

    Along with the urbanization of rural areas on Ryukyu Islands, many shell mounds and pre-historic sites have been found in resent years. Chrological studies of shell samples from these mounds will lead to the better understanding of cultural background for the pre-historic human activities on the Ryukyu Islands. C-14 dating by beta counting is the common method to obtain the ages of the archaeological samples. It is, however, very limitted in obtaining the absolute ages by the above mehtod due to the large sample sizes required and time consuming. There are many newly obtained archaeological samples left unstudied in detail. The alternate is a method called Tandem Accelerator Mass Spectrometer (AMS) installed at Nagoya University, which is composed of the tandem type accelerator to measure very low concentration of C-14 in archaeological samples. The system has been designed particularly to measure the radio-carbon and has advantages of being small sample size and very little time consuming for C-14 measurement as compared with the beta counting. It is the aim of this work to apply the above AMS for obtaining the absolute ages of the archaeological samples. The results agreed well with those estimated by the Erthenware method (relative method of dating), which ranged from 500 to 6000 y.b.p. The results may be helpful for the chronological arrangement of the samples and for the understanding of pre-historical human activities on the Ryukyu Islands. (author)

    It is well known that in Archaeology large use is done of digital technologies and computer applications for data acquisition, storage, analysis and visualisation. In the last years the amount of information coming from remote sensing. from precise and fast acquisition of 3-D artefacts images by scanners laser, from GPS precise reference of geographical points and from other human and natural sciences are increasing at a large extent the amount of data that it need to be stored and made available for analysis. Moreover the use of Virtual Archaeology as a new approach to the narration and visualisation in Archaeology, is expanding rapidly, not only in the museum and archaeology professions, but also in the broadcast media, tourism and heritage industries. From another side recent natural and social disasters (wars) created enormous damages to the archaeological heritage and in many case destroyed definitively any information about ancient civilisations.

  8. When Archaeology Begins: The Cultural and Political Context of Chinese Archaeological Thought

    Directory of Open Access Journals (Sweden)

    Xinyi Liu

    2008-05-01

    Full Text Available Since the beginning of the 19th century, the construction of world history has been dominated by Western Europe. In Jack Goody’s recent work, The Theft of History (2007, he demonstrates that the interpretation of the past is conceptualized and presented according to what happened in Europe, and more often in Western Europe. Chinese archaeology, under the control of Western imperialism in the early 20th century, believed that it had to destroy Confucianism and come up with a new philosophy. However, with the arrival of many different kinds of western ideas, such as evolution and diffusion, Chinese archaeology was reformulated many times. Such issues have been discussed in several publications (Chen 1997; Liu and Chen 1999; Falkenhausen 1993. In this paper, we reexamine some of the key concepts of Chinese archaeological thought.

    The identification of natural dyes found in archaeological objects and in works of art as textile dyes and lake pigments is a demanding analytical task. To address the problems raised by the very low dye content of dyed fibers and lake pigments, and by the requirement to remove only microscopic samples, surface enhanced Raman scattering techniques were investigated for application to museum objects. SERS gives excellent results with the majority of natural dyes, including: alizarin, purpurin, laccaic acid, carminic acid, kermesic acid, shikonin, juglone, lawsone, brazilin and brazilein, haematoxylin and haematein, fisetin, quercitrin, quercetin, rutin, and morin. In this study, limits of detection were determined for representative dyes and different SERS supports such as citrate reduced Ag colloid and silver nanoisland films. SERS was successfully used to identify natural madder in a microscopic fragment from a severely degraded 11th Century Byzantine textile recently excavated in Amorium, Turkey.

    Science.gov (United States)

    Parham, David; Palma, Paola

    2008-12-01

    This paper draws on experience gained by Bournemouth University to consider undergraduate education in maritime archaeology. At Bournemouth maritime archaeology is taught firmly in the context of a broader archaeological education. Archaeological programmes vary with the institutions within which they are taught, each programme thus having an individual character that separates it from that of other institutions and further enriches the subject through the breadth of this education. At Bournemouth the value of teaching archaeology with a high component of practical experience has been long understood. This does not mean that archaeology is taught as a purely practical subject but as one within which experience in the field is seen as a worthwhile focus. Bournemouth’s programme therefore recognises the value of field research projects as learning environments for undergraduates studying maritime archaeology. The programme is subject to a number of constraints, notably the size of the archaeological employment market, levels of pay within that market, questions of ongoing professional development after graduation, and the requirements of other employment markets into which archaeological graduates enter. This paper argues that research project-based learning, and in particular, involvement with amateur groups, provides a way to balance these constraints and supports development of both technical and transferable ‘soft’ skills.

  13. Nutrient regulation by continuous feeding removes limitations on cell yield in the large-scale expansion of Mammalian cell spheroids.

    Directory of Open Access Journals (Sweden)

    Bradley P Weegman

    Full Text Available Cellular therapies are emerging as a standard approach for the treatment of several diseases. However, realizing the promise of cellular therapies across the full range of treatable disorders will require large-scale, controlled, reproducible culture methods. Bioreactor systems offer the scale-up and monitoring needed, but standard stirred bioreactor cultures do not allow for the real-time regulation of key nutrients in the medium. In this study, β-TC6 insulinoma cells were aggregated and cultured for 3 weeks as a model of manufacturing a mammalian cell product. Cell expansion rates and medium nutrient levels were compared in static, stirred suspension bioreactors (SSB, and continuously fed (CF SSB. While SSB cultures facilitated increased culture volumes, no increase in cell yields were observed, partly due to limitations in key nutrients, which were consumed by the cultures between feedings, such as glucose. Even when glucose levels were increased to prevent depletion between feedings, dramatic fluctuations in glucose levels were observed. Continuous feeding eliminated fluctuations and improved cell expansion when compared with both static and SSB culture methods. Further improvements in growth rates were observed after adjusting the feed rate based on calculated nutrient depletion, which maintained physiological glucose levels for the duration of the expansion. Adjusting the feed rate in a continuous medium replacement system can maintain the consistent nutrient levels required for the large-scale application of many cell products. Continuously fed bioreactor systems combined with nutrient regulation can be used to improve the yield and reproducibility of mammalian cells for biological products and cellular therapies and will facilitate the translation of cell culture from the research lab to clinical applications.

Bioreactor systems offer the scale-up and monitoring needed, but standard stirred bioreactor cultures do not allow for the real-time regulation of key nutrients in the medium. In this study, β-TC6 insulinoma cells were aggregated and cultured for 3 weeks as a model of manufacturing a mammalian cell product. Cell expansion rates and medium nutrient levels were compared in static, stirred suspension bioreactors (SSB), and continuously fed (CF) SSB. While SSB cultures facilitated increased culture volumes, no increase in cell yields were observed, partly due to limitations in key nutrients, which were consumed by the cultures between feedings, such as glucose. Even when glucose levels were increased to prevent depletion between feedings, dramatic fluctuations in glucose levels were observed. Continuous feeding eliminated fluctuations and improved cell expansion when compared with both static and SSB culture methods. Further improvements in growth rates were observed after adjusting the feed rate based on calculated nutrient depletion, which maintained physiological glucose levels for the duration of the expansion. Adjusting the feed rate in a continuous medium replacement system can maintain the consistent nutrient levels required for the large-scale application of many cell products. Continuously fed bioreactor systems combined with nutrient regulation can be used to improve the yield and reproducibility of mammalian cells for biological products and cellular therapies and will facilitate the translation of cell culture from the research lab to clinical applications.

  20. Archaeological Evidence for Resilience of Pacific Northwest Salmon Populations and the Socioecological System over the last ~7,500 years

    Directory of Open Access Journals (Sweden)

    Sarah K. Campbell

    2010-03-01

    Full Text Available Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the ecological-human system. Of several factors possibly contributing to resilience, low human population size and harvesting pressure, habitat enhancement, and suppression of competing predators do not appear to be of major importance. Flexible resource use, including human use of a range of local resources, many of which are linked in a food web with salmon, likely contributed to resilience. Most important were the beliefs and social institutions (including ownership, regulation, rituals, and monitoring that placed restraints on salmon use as a common pool resource. In contrast, only a small fraction of our modern society relies economically on or has direct interaction with the fish, which limits our concern and willingness to fundamentally change behaviors that contribute to habitat degradation and loss, the main challenges facing salmon populations today. Salmon recovery efforts may benefit substantially from investing more resources into establishing links between community groups and actual fish populations, which would create a sense of proprietorship, one of the keys to resilience in the indigenous salmon fishery.

    2016-07-01

    Full Text Available Aerial archaeology has more than one century of tradition as a valuable research method. Like archaeology, the aerial reconnaissance is undergoing dynamic changes. The field must face the profound conceptual challenges raised by the evolving demands of archaeologists. In addition, aerial archaeology has to adapt its own methods in order to constantly incorporate new technologies such as: thermal vision, LiDAR and also advanced photogrammetry processing techniques. One of the greatest challenges and promising perspectives for evolution of the field is the arriving and rapidly spreading of small remote controlled aerial vehicles (UAVs – Unmanned Aerial Vehicles, known also as drones. However, a real development of the UAVs based aerial archaeology’s branch is conditioned by the availability of special tailored aerial vehicles for archaeologist’s needs. Unfortunately, the time has not yet come for this, while the major efforts in drones development is spent for aerial videography applications, surveillance and general entertainment. The implementation of a research project, dedicated to the longest built sector of the Roman limes in Dacia – Limes Transalutanus, represented for the authors a suitable occasion to assess the possibilities and limits of the large scale aerial archaeology based on UAVs. On the occasion there were tested two custom flying platforms and one commercial, multiple flight strategies and several processing algorithms. The linear nature and the extent of the site (basically a corridor of 157 km in length called for distinct augmentation of equipment and survey workflows, with applicability in ‘corridor’ archaeological projects like those for highways and utilities networks.

  2. Archaeological and Geological dating by means of thermoluminescence

    1999-01-01

    In this thesis an specific method for dating local archaeological and geological samples based on the phenomenon of thermoluminescence (TL) using the fine grain and quartz inclusion techniques is developed. Taking into account that this work is interesting for professionals working in the fields of Physics, Chemistry, Archaeology, Anthropology and related sciences, some basic concepts are described to have a better comprehension. Chapter 1 describes the concept of radioactivity, remarking the importance of the different decay types as well as the main radioactive series and the energy liberated in the process. The causes of radioactive desequilibrium are also considered in the case for radon. Another important aspect taken into account in this chapter is the radioisotope production and its relationship with the neutron activation analysis used for the determination of the Uranium and Thorium concentrations in the samples. The TL phenomenon is described in Chapter 2, emphasizing the importance of the process of thermally stimulated luminescence best known as TL and its application for dating minerals of different origin. Chapter 3 shows some important antecedents remarking some aspects of the techniques commonly used for dating purposes. Chapter 4 shows the different methods used for the sample preparation. The techniques used for the 40 K, 238 U and 232 Th determination as well as for the cosmic radiation measurement using locally made TLD are also described. The methods used for the determination of the paleodosis as a function of the TL intensity of each sample are described: special emphasis is taken on the moisture effects as well as in the error limits in the age estimation. Results and conclusions of this study are presented in Chapter 5. These results gave an age of 980 ± 90 years for the Edzna ceramic and 1520 ± 90 years for the Calixtlahuaca ceramics. The age of the Teotihuacan ceramics was not estimated due to the lack of a stable region of the traps

  15. The Archaeologist Undeceived: Selecting Quality Archaeological Information from the Internet

    Directory of Open Access Journals (Sweden)

    Paul Sturges

    2003-01-01

    Full Text Available The amount of unreliable information and actual misinformation available via the Internet makes its use problematic for academic purposes, particularly for data-intensive disciplines such as archaeology. Whilst there are many sources for reviews of websites, few apply the type of criteria most appropriate to archaeology. Information and library professionals have developed sets of criteria that can be adapted for the evaluation of archaeological websites. An evaluative tool for archaeological websites, using al-ready-available criteria, was developed and tested on twenty archaeological web sites. It proved capable of allowing its user to make clear distinctions between sites on the basis of quality. Further refining of the evaluative tool is possible on the basis of testing by both archaeologists and information professionals.

  16. Novel plant communities limit the effects of a managed flood to restore riparian forests along a large regulated river

    Science.gov (United States)

    Cooper, D.J.; Andersen, D.C.

    2012-01-01

    Dam releases used to create downstream flows that mimic historic floods in timing, peak magnitude and recession rate are touted as key tools for restoring riparian vegetation on large regulated rivers. We analysed a flood on the 5th-order Green River below Flaming Gorge Dam, Colorado, in a broad alluvial valley where Fremont cottonwood riparian forests have senesced and little recruitment has occurred since dam completion in 1962. The stable post dam flow regime triggered the development of novel riparian communities with dense herbaceous plant cover. We monitored cottonwood recruitment on landforms inundated by a managed flood equal in magnitude and timing to the average pre-dam flood. To understand the potential for using managed floods as a riparian restoration tool, we implemented a controlled and replicated experiment to test the effects of artificially modified ground layer vegetation on cottonwood seedling establishment. Treatments to remove herbaceous vegetation and create bare ground included herbicide application (H), ploughing (P), and herbicide plus ploughing (H+P). Treatment improved seedling establishment. Initial seedling densities on treated areas were as much as 1200% higher than on neighbouring control (C) areas, but varied over three orders of magnitude among the five locations where manipulations were replicated. Only two replicates showed the expected seedling density rank of (H+P)>P>H>C. Few seedlings established in control plots and none survived 1 year. Seedling density was strongly affected by seed rain density. Herbivory affected growth and survivorship of recruits, and few survived nine growing seasons. Our results suggest that the novel plant communities are ecologically and geomorphically resistant to change. Managed flooding alone, using flows equal to the pre-dam mean annual peak flood, is an ineffective riparian restoration tool where such ecosystem states are present and floods cannot create new habitat for seedling establishment

  17. Multivariate and Spatial Visualisation of Archaeological Assemblages

    Directory of Open Access Journals (Sweden)

    Martin Sterry

    2018-05-01

    Full Text Available Multivariate analyses, in particular correspondence analysis (CA, have become a standard exploratory tool for analysing and interpreting variance in archaeological assemblages. While they have greatly helped analysts, they unfortunately remain abstract to the viewer, all the more so if the viewer has little or no experience with multivariate statistics. A second issue with these analyses can arise from the detachment of archaeological material from its geo-referenced location and typically considered only in terms of arbitrary classifications (e.g. North Europe, Central Europe, South Europe instead of the full range of local conditions (e.g. proximity to other assemblages, relationships with other spatial phenomena. This article addresses these issues by presenting a novel method for spatially visualising CA so that these analyses can be interpreted intuitively. The method works by transforming the resultant bi-plots of the CA into colour maps using the HSV colour model, in which the similarity and difference between assemblages directly corresponds to the similarity and difference of the colours used to display them. Utilising two datasets – ceramics from the excavations of the Roman fortress of Vetera I, and terra sigillata forms collected as part of 'The Samian Project' – the article demonstrates how the method is applied and how it can be used to draw out spatial and temporal trends.

  18. What is Common to Anthropology and Archaeology?

    Directory of Open Access Journals (Sweden)

    Giulio Angioni

    2016-07-01

    Full Text Available This  essay discusses  the idea that archaeology, precisely like anthropology, must continually deal with the Western millennial habit to divide life into different areas (doing, saying, thinking, feeling ... and sort them into hierarchies. Perhaps the greatest cognitive and practical task of every anthropology and archaeology is to be able to connect together at par, thus turning them into a 'useful 'truth', either that the whole world is the same  and that “in Rome do as Romans do”, i. e. to understand and use the positivity and avoid the negativity of prescriptions wanting that “wright or wrong, my country”. Following only the human invariance or identity, or just following only the variety of ways of living, has caused great oversights and serious troubles. Archaeologists and anthropologists should know better than others that if men are always the same and always different, then they cannot be reduced  to their identity of species or to their different lifestyles.

  19. Landscape Pattern Detection in Archaeological Remote Sensing

    Directory of Open Access Journals (Sweden)

    Arianna Traviglia

    2017-12-01

    Full Text Available Automated detection of landscape patterns on Remote Sensing imagery has seen virtually little or no development in the archaeological domain, notwithstanding the fact that large portion of cultural landscapes worldwide are characterized by land engineering applications. The current extraordinary availability of remotely sensed images makes it now urgent to envision and develop automatic methods that can simplify their inspection and the extraction of relevant information from them, as the quantity of information is no longer manageable by traditional “human” visual interpretation. This paper expands on the development of automatic methods for the detection of target landscape features—represented by field system patterns—in very high spatial resolution images, within the framework of an archaeological project focused on the landscape engineering embedded in Roman cadasters. The targets of interest consist of a variety of similarly oriented objects of diverse nature (such as roads, drainage channels, etc. concurring to demark the current landscape organization, which reflects the one imposed by Romans over two millennia ago. The proposed workflow exploits the textural and shape properties of real-world elements forming the field patterns using multiscale analysis of dominant oriented response filters. Trials showed that this approach provides accurate localization of target linear objects and alignments signaled by a wide range of physical entities with very different characteristics.

    Vandiver, P.B.; Druzik, J.; Wheeler, G.S.

    1991-01-01

    the purpose of this meeting is to present new and current research which: shares an empirical methodology of observation and measurement; concerns interdisciplinary studies of art, archaeology, architecture, ancient technology, and conservation; and uses the knowledge, methods and tools of materials science and engineering. Druzik introduced the symposium as follows: It is not inaccurate to say that Materials Issues in Art and Archaeology II is a continuing experiment. It is an experiment in the sense that conservation scientists, materials scientists who usually deal with the properties and processing of modern technology, and those who study the materials and processing of ancient cultures seldom have an opportunity to experience each other's unique problems. While the conservation of artistic and cultural properties often involves the very same objects as those studied by students of ancient technology these two specialized species seldom, if ever, attend the same meetings, publish in the same journals, or can even name a paltry subset of the other discipline's more famous characters and controversies. And, what do the Real Material Scientists think of these two odd birds. Well, that's what we really want to find out. Because it's certainly clear to myself and my co-organizers that the MRS has undreamed of potential and wealth to help solve many of the questions we pose about past cultures, their tools, their aesthetic sensibilities and their preservation for future generations were we only imaginative enough to exploit it

    A quantitative morphological analysis of archaeological objects represents an important element for historical evaluations, artistic studies and conservation projects. At present, a variety of contact instruments for high-resolution surface survey is available on the market, but because of their invasivity they are not well received in the field of artwork conservation. On the contrary, optical testing techniques have seen a successful growth in last few years due to their effectiveness and safety. In this work we present a few examples of application of high-resolution 3D techniques for the survey of archaeological objects. Measurements were carried out by means of an optical micro-profilometer composed of a commercial conoprobe mounted on a scanning device that allows a maximum sampled area of 280×280 mm2. Measurements as well as roughness calculations were carried out on selected areas, representative of the differently degraded surface, of an ellenestic bronze statue to document the surface corrosion before restoration intervention started. Two highly-corroded ancient coins and a limestone column were surveyed to enhance the relief of inscriptions and drawings for dating purposes. High-resolution 3D survey, beyond the faithful representation of objects, makes it possible to display the surface in an image format that can be processed by means of image processing software. The application of digital filters as well as rendering techniques easies the readability of the smallest details.

  2. Classification of archaeologically stratified pumice by INAA

    International Nuclear Information System (INIS)

    Peltz, C.; Bichler, M.

    2001-01-01

    In the framework of the research program 'Synchronization of Civilization in the Eastern Mediterranean Region in the 2nd Millenium B.C.' instrumental neutron activation analysis (INAA) was used to determine 30 elements in pumice from archaeological excavations to reveal their specific volcanic origin. The widespread pumiceous products of several eruptions in the Aegean region were used as abrasive tools and were therefore popular trade objects. A remarkable quantity of pumice and pumiceous tephra (several km 3 ) was produced by the 'Minoan eruption' of Thera (Santorini), which is assumed to have happened between 1450 and 1650 B.C. Thus the discovery of the primary fallout of 'Minoan' tephra in archaeologically stratified locations can be used as a relative time mark. Additionally, pumice lumps used as abrasive can serve for dating by first appearance. Essential to an identification of the primary volcanic source is the knowledge that pumices from the Aegean region can easily be distinguished by their trace element distribution patterns, as previous work has shown. The elements Al, Ba, Ca, Ce, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mn, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, Ti, U, V, Yb, Zn and Zr were determined in 16 samples of pumice lumps from excavations in Tell-el-Dab'a and Tell-el-Herr (Egypt). Two irradiation cycles and five measurement runs were applied. A reliable identification of the samples is achieved by comparing these results to the database compiled in previous studies. (author)

    Full Text Available Palazzo Valentini, a historical site of Rome׳s Provincial Administration, is located at the heart of the city. The building was purchased in 1827 by Vincenzo Valentini, a banker and consul general of the Prussian Crown. In 1939, with the outbreak of World War II, a fully self-contained, air-raid shelter was built under the courtyard, with an exit tunnel heading onto the Trajan׳s Forum. Archaeological investigations started in 2005 in view of a simple rehabilitation work of the underground level. As work progressed, the sample-plots brought to light new archaeological findings: relics of a huge temple and what remained of two residential houses with thermal baths. We therefore designed an exhibition space with glass surfaces to allow visitors to appreciate the findings while following a path through historical ages: from the 16th-century courtyard to the underground Roman domus (the sumptuous houses of senators and dignitaries of the Roman Empire, with private baths, to the remains of a Roman temple, and all the way to the Trajan׳s Column pedestal by way of the air-raid shelter. Virtual reconstructions, graphic effects, and movies are the means used to revive the hypothetical original appearance of the environments and the daily life of that epoch in order to help us build a prototype of an on-site museum of the third millennium.

    One of the popular uses of UAVs in photogrammetry is providing an archaeological documentation. A wide offer of low-cost (consumer) grade UAVs, as well as the popularity of user-friendly photogrammetric software allowing obtaining satisfying results, contribute to facilitating the process of preparing documentation for small archaeological sites. However, using solutions of this kind is much more problematic for larger areas. The limited possibilities of autonomous flight makes it significantly harder to obtain data for areas too large to be covered during a single mission. Moreover, sometimes the platforms used are not equipped with telemetry systems, which makes navigating and guaranteeing a similar quality of data during separate flights difficult. The simplest solution is using a better UAV, however the cost of devices of such type often exceeds the financial capabilities of archaeological expeditions. The aim of this article is to present methodology allowing obtaining data for medium scale areas using only a basic UAV. The proposed methodology assumes using a simple multirotor, not equipped with any flight planning system or telemetry. Navigating of the platform is based solely on live-view images sent from the camera attached to the UAV. The presented survey was carried out using a simple GoPro camera which, from the perspective of photogrammetric use, was not the optimal configuration due to the fish eye geometry of the camera. Another limitation is the actual operational range of UAVs which in the case of cheaper systems, rarely exceeds 1 kilometre and is in fact often much smaller. Therefore the surveyed area must be divided into sub-blocks which correspond to the range of the drone. It is inconvenient since the blocks must overlap, so that they will later be merged during their processing. This increases the length of required flights as well as the computing power necessary to process a greater number of images. These issues make prospection highly

    Full Text Available The recognition in the West that every discipline is influenced by its socio-political context led to the demand for reflexive archaeology and to the formation in 1986, by the 'politically aware', of the World Archaeological Congress (WAC. WAC explicitly recognises the socio-political context of archaeological practice, and archaelogy's political, social and academic responsibilities. The Congress, which meets every four years, met in India in December 1994. Indian archaeologists have largely denied the influence of socio-political contexts on academics. But this has not prevented some from (misusing archaeological evidence to further political ends with catastrophic results. No discussion on the issue was permitted at the Congress so that eight years after it was formed. the WAC compromised and suppressed free debate on a vital matter. This essay outlines the genesis of WAC and the reasons why it was formed, before analysing the Indian context of the third meeting of the Congress. It also examines the response of Indian archaeologists at WAC to the protest against such political abuse of archaeology and calls for a reflection on whether WAC has achieved its objective of becoming a relevant world organisation.

    Theory suggests that natural fire regimes can result in landscapes that are both self-regulating and resilient to fire. For example, because fires consume fuel, they may create barriers to the spread of future fires, thereby regulating fire size. Top-down controls such as weather, however, can weaken this effect. While empirical examples demonstrating this pattern-...

    2007-11-01

    Full Text Available This article will consider the implications of the Yorkshire regional assessment for how we categorise, analyse and synthesise the past. It argues that we must transcend the existing frameworks, especially their chronological elements, if we are to fully engage with the evidence currently at our disposal, and do so in a way which takes account of all of its lacunae and limitations, yet details and potentials. This has implications not only for the UK, but for problems facing archaeologists across the world: how to organise, within a coherent framework, the rapidly accumulating masses of data generated by developer-led archaeology and its international equivalents in cultural resource management, and how to forge a stronger relationship between the academic and curatorial spheres of archaeological endeavour.

  9. Archaeological studies at Drill Hole U20az Pahute Mesa, Nye county, Nevada. [Contains bibliography

    Simmons, A.H.; Hemphill, M.L.; Henton, G.H.; Lockett, C.L.; Nials, F.L.; Pippin, L.C.; Walsh, L.

    1991-07-01

    During the summer of 1987, the Quaternary Sciences Center (formerly Social Science Center) of the Desert Research Institute (DRI), University of Nevada System, conducted data recovery investigations at five archaeological sites located near Drill Hole U20az on the Nevada Test Site in southern Nevada. These sites were among 12 recorded earlier during an archaeological survey of the drill hole conducted as part of the environmental compliance activities of the Department of Energy (DOE). The five sites discussed in this report were considered eligible for the National Register of Historic Places and were in danger of being adversely impacted by construction activities or by effects of the proposed underground nuclear test. Avoidance of these sites was not a feasible alternative; thus DRI undertook a data recovery program to mitigate expected adverse impacts. DRI's research plan included controlled surface collections and excavation of the five sites in question, and had the concurrence of the Nevada Division of Historic Preservation and Archaeology and the Advisory Council of Historic Preservation. Of the five sites investigated, the largest and most complex, 26Ny5207, consists of at least three discrete artifact concentrations. Sites 26Ny5211 and 26Ny5215, both yielded considerable assemblages. Site 26Ny5206 is very small and probably is linked to 26Ny5207. Site 26Ny5205 contained a limited artifact assemblage. All of the sites were open-air occurrences, and, with one exception contained no or limited subsurface cultural deposits. Only two radiocarbon dates were obtained, both from 26Ny5207 and both relatively recent. While the investigations reported in the volume mitigate most of the adverse impacts from DOE activities at Drill Hole U20az, significant archaeological sites may still exist in the general vicinity. Should the DOE conduct further activities in the region, additional cultural resource investigations may be required. 132 refs., 71 figs., 44 tabs.

    2011-12-01

    Full Text Available This contribution presents a series of investigations undertaken thanks to the collaboration between the Department of Architecture and Territorial Planning of the University of Bologna and the Archaeological Museum of Bologna , aimed at finding a procedure for the 3d digital survey and exploration of archaeological finds. In particular, this paper shows how users can benefit from the use of digital technologies for the fruition of historical-artistic heritage. As a matter of fact, digital communication tools stimulate multisensory perception mechanisms and therefore allow to actively involve users in the exploration of contents presented through collections. Immersive visualizations, augmented reality and both tactile and visual exploration of findings can ease the establishment of a more immediate and direct communication channel with users that generally communicate and access information using digital technologies and mediums.

  11. Starry messages: Searching for signatures of interstellar archaeology

    Energy Technology Data Exchange (ETDEWEB)

    Carrigan, Richard A., Jr.; /Fermilab

    2009-12-01

    Searching for signatures of cosmic-scale archaeological artifacts such as Dyson spheres or Kardashev civilizations is an interesting alternative to conventional SETI. Uncovering such an artifact does not require the intentional transmission of a signal on the part of the original civilization. This type of search is called interstellar archaeology or sometimes cosmic archaeology. The detection of intelligence elsewhere in the Universe with interstellar archaeology or SETI would have broad implications for science. For example, the constraints of the anthropic principle would have to be loosened if a different type of intelligence was discovered elsewhere. A variety of interstellar archaeology signatures are discussed including non-natural planetary atmospheric constituents, stellar doping with isotopes of nuclear wastes, Dyson spheres, as well as signatures of stellar and galactic-scale engineering. The concept of a Fermi bubble due to interstellar migration is introduced in the discussion of galactic signatures. These potential interstellar archaeological signatures are classified using the Kardashev scale. A modified Drake equation is used to evaluate the relative challenges of finding various sources. With few exceptions interstellar archaeological signatures are clouded and beyond current technological capabilities. However SETI for so-called cultural transmissions and planetary atmosphere signatures are within reach.

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

    The subject of this article is the possibilities of the documentation of a defunct town from the Pre-Islamic period to Early Islamic period. This town is located near the town Makhmur in Iraq. The Czech archaeological mission has worked at this dig site. This Cultural Heritage site is threatened by war because in the vicinity are positions of ISIS. For security reasons, the applicability of Pleiades satellite data has been tested. Moreover, this area is a no-fly zone. However, the DTM created from stereo-images was insufficient for the desired application in archeology. The subject of this paper is the testing of the usability of RPAS technology and terrestrial photogrammetry for documentation of the remains of buildings. RPAS is a very fast growing technology that combines the advantages of aerial photogrammetry and terrestrial photogrammetry. A probably defunct church is a sample object.

This book offers the first interpretation of social life at these key sites, and proposes a series of innovative, theoretically informed frames for exploring the significance of the material remains...... of identity formation. It makes a case for the heretofore unrecognised significance of an ‘aesthetic’ identity mediated by material culture. It approaches X-Group culture as a materially complex indigenous culture that created and altered identities through time via the manipulation of materials, colours...... occasions, and the rise of certain individuals. The interpretations put forward here are based on a systematic quantitative analysis of the archaeological material from the sites. These analyses draw on complex typologies differentiating objects according to use, ware, colour, decoration method, designs...

  17. Complex adaptative systems and computational simulation in Archaeology

    2017-07-01

    Full Text Available Traditionally the concept of ‘complexity’ is used as a synonym for ‘complex society’, i.e., human groups with characteristics such as urbanism, inequalities, and hierarchy. The introduction of Nonlinear Systems and Complex Adaptive Systems to the discipline of archaeology has nuanced this concept. This theoretical turn has led to the rise of modelling as a method of analysis of historical processes. This work has a twofold objective: to present the theoretical current characterized by generative thinking in archaeology and to present a concrete application of agent-based modelling to an archaeological problem: the dispersal of the first ceramic production in the western Mediterranean.

    In 2013, an airborne laser scan survey was conducted in the territory of the Ionian city of Kolophon near the western coast of modern Turkey as part of an archaeological survey project carried out by the Mimar Sinan University of Istanbul (Turkey) and the University of Vienna (Austria). Several light detection and ranging (LiDAR) studies have been carried out in the temperate climate zones of Europe, but only a few in Mediterranean landscapes. Our study is based on the first LiDAR survey carried out for an archaeological purpose in Turkey and one of the first in the Mediterranean that have been planned, measured and filtered especially for archaeological research questions. The interpretation of LiDAR data combined with ground-observations proved extremely useful for the detection and documentation of archaeological remains below Mediterranean evergreen vegetation and dense maquis. This article deals with the methodological aspects of interpreting LiDAR data, using the Kolophon data as a case study. We offer a discussion of the strengths and limitations of LiDAR as an archaeological remote sensing method and suggest a best practice model for interpreting LiDAR data in a Mediterranean context. © 2017 The Authors.

    Full Text Available Abstract Background In Escherichia coli, pH regulates genes for amino-acid and sugar catabolism, electron transport, oxidative stress, periplasmic and envelope proteins. Many pH-dependent genes are co-regulated by anaerobiosis, but the overall intersection of pH stress and oxygen limitation has not been investigated. Results The pH dependence of gene expression was analyzed in oxygen-limited cultures of E. coli K-12 strain W3110. E. coli K-12 strain W3110 was cultured in closed tubes containing LBK broth buffered at pH 5.7, pH 7.0, and pH 8.5. Affymetrix array hybridization revealed pH-dependent expression of 1,384 genes and 610 intergenic regions. A core group of 251 genes showed pH responses similar to those in a previous study of cultures grown with aeration. The highly acid-induced gene yagU was shown to be required for extreme-acid resistance (survival at pH 2. Acid also up-regulated fimbriae (fimAC, periplasmic chaperones (hdeAB, cyclopropane fatty acid synthase (cfa, and the "constitutive" Na+/H+ antiporter (nhaB. Base up-regulated core genes for maltodextrin transport (lamB, mal, ATP synthase (atp, and DNA repair (recA, mutL. Other genes showed opposite pH responses with or without aeration, for example ETS components (cyo,nuo, sdh and hydrogenases (hya, hyb, hyc, hyf, hyp. A hypF strain lacking all hydrogenase activity showed loss of extreme-acid resistance. Under oxygen limitation only, acid down-regulated ribosome synthesis (rpl,rpm, rps. Acid up-regulated the catabolism of sugar derivatives whose fermentation minimized acid production (gnd, gnt, srl, and also a cluster of 13 genes in the gadA region. Acid up-regulated drug transporters (mdtEF, mdtL, but down-regulated penicillin-binding proteins (dacACD, mreBC. Intergenic regions containing regulatory sRNAs were up-regulated by acid (ryeA, csrB, gadY, rybC. Conclusion pH regulates a core set of genes independently of oxygen, including yagU, fimbriae, periplasmic chaperones, and nha

  1. Reciprocal Regulation of GlnR and PhoP in Response to Nitrogen and Phosphate Limitations in Saccharopolyspora erythraea

    Yao, Li-li

    2015-01-01

    Nitrogen and phosphate source sensing, uptake, and assimilation are essential for the growth and development of microorganisms. In this study, we demonstrated that SACE_6965 encodes the phosphate regulator PhoP, which controls the transcription of genes involved in phosphate metabolism in the erythromycin-producing Saccharopolyspora erythraea. We found that PhoP and the nitrogen regulator GlnR both regulate the transcription of glnR as well as other nitrogen metabolism-related genes. Interestingly, both GlnR- and PhoP-binding sites were identified in the phoP promoter region. Unlike the nonreciprocal regulation of GlnR and PhoP observed in Streptomyces coelicolor and Streptomyces lividans, GlnR negatively controls the transcription of the phoP gene in S. erythraea. This suggests that GlnR directly affects phosphate metabolism and demonstrates that the cross talk between GlnR and PhoP is reciprocal. Although GlnR and PhoP sites in the glnR and phoP promoter regions are located in close proximity to one another (separated by only 2 to 4 bp), the binding of both regulators to their respective region was independent and noninterfering. These results indicate that two regulators could separately bind to their respective binding sites and control nitrogen and phosphate metabolism in response to environmental changes. The reciprocal cross talk observed between GlnR and PhoP serves as a foundation for understanding the regulation of complex primary and secondary metabolism in antibiotic-producing actinomycetes.

    2002-03-01

    Full Text Available The City of York Council has been pursuing a strict policy of in situ preservation of archaeological deposits since April 1990. Planning consent is normally granted in the historic core of York for a new development so long as less than 5% of the archaeological deposits that are preserved on a site are destroyed. During archaeological evaluation work carried out as part of the redevelopment and expansion proposals for Marks & Spencer plc on Parliament Street, deposit monitoring devices were installed to investigate and monitor both the character of the archaeological deposits present and also the burial environment surrounding them (of particular importance because the burial environment, in terms both of its characteristics and stability, is thought to play a vital role in the preservation in situ of a site's archaeological deposits. The monitoring programme was undertaken between June 1995 and April 1998. As a result the data from a total of 30 site visits have been collected and are presented in this report. This article discusses results of the deposit monitoring project and presents evidence of changes that appear to be taking place in the archaeological deposits. Although the lower deposits at Parliament Street are stable, the upper deposits show considerable seasonal variations. The concept of preservation of archaeological deposits in situ is now deeply embedded both in Codes of Professional Conduct (IFA Code of Conduct and in national policy guidance (PPG 16. However, this emphasis on preservation in situ has been criticised. Does conservation archaeology in general and the City of York policy in particular achieve the preservation of the remaining 95% of the archaeology? Or are these deposits condemned to unseen, unrecorded destruction, sealed below new buildings; indeed if this is the case, shouldn't these deposits be excavated now while they are still viable?

    The analytical exploitation of the laser induced plasma suffers from its transient behavior due to some nonlinear effects. These phenomena are matrix-dependent and limit the use of LIBS to mostly semi-quantitative precision. The plasma parameters have to be kept as constant as possible during LIBS measurements. Studying archaeological bone samples using LIBS technique could be more difficult since these samples are less tough in their texture than many other solid samples. Thus, the ablation process could change the sample morphological features rapidly resulting in poor reproducibility and statistics. Furthermore archaeological bones are subjected to diagenesis effects due to burial environment and postmortem effects. In the present work comparative analytical study of UV (266 nm) and IR (1064 nm) LIBS for archaeological bone samples belonging to four ancient Egyptian dynasties representing the middle kingdom (1980–1630 BC), 2nd intermediate period (1630–1539/23 BC), Roman–Greek period (30 BC–A.D. 395) and the late period (664–332 BC). Measurements have been performed under identical experimental conditions except the laser wavelength to examine its effects. Elemental fluctuations within the same dynasty were studied for reliable information about each dynasty. The analytical results demonstrated that UV-LIBS gives a more realistic picture for bone elemental composition within the same dynasty, and bone ash could be more suitable as a reference material for bone calibration in the case of UV-LIBS. - Highlights: • UV and IR LIBS for archaeological bone samples have been performed. • Elemental fluctuations within the same dynasty were studied. • UV-LIBS gave realistic picture for bone elemental composition for the same dynasty. • Depth profile for Sr/Ca concentration was an indicator for the diagenesis effect. • Bone ash is the most suitable for calcified tissue calibration for UV-LIBS.

    Dating is the key to organising all archaeological evidence. Furthermore, the development of dating methods, whether traditional or scientific, illustrates the ingenuity and lateral thinking that make archaeological problem-solving such a fascinating exercise. The development of MINT radiocarbon dating procedures is reviewed. Basic principles and counting techniques are discussed. A sample is converted by chemical methods into a suitable form, such as carbon dioxide followed by the acetylene gas, and the benzene end-product is placed inside a proportional counter to measure the radioactivity of 14 C. Not until some years ago did absolute dates by radiocarbon dating become a reality for prehistoric archaeology in Malaysia where thermoluminescence and fission-track dating had begun to provide a locally applicable dating method some decades earlier. Applications of radiocarbon dating procedures in the fields of archaeology are also discussed. (Author)

    In the last decade the use of Ground Penetrating radar (GPR) applied to cultural heritage has been strongly increasing thanks to both technological development of sensors and softwares for data processing and cultural reasons such as the increasing awareness of conservators and archaeologist of the benefits of this method in terms of reduction of costs and time and risk associated with restoration works. This made GPR a mature technique for investigating different types of works of art and building elements of historical interest, including masonry structures, frescoes, mosaics [1-3], in the context of scientific projects, decision support activities aimed at the diagnosis of decay pathologies, and educational activities. One of the most complex building elements to be investigated by GPR are the columns both for the geometry of the object and for the several expected features to be detected including fractures, dishomogeneities and metallic connection elements. The work deals with the Ground Penetrating Radar diagnostic surveys at the prestigious archaeological site of Pompei. In particular, GPR surveys were carried out in two different areas, Palestra Grande and Tempio di Giove. The first campaign was carried out also as educational activity of the "International School "GEOPHYSICS AND REMOTE SENSING FOR ARCHAEOLOGY". The School aimed at giving the opportunity to scholars, PhD students, researchers and specialists in Geophysics, Remote Sensing and Archaeology to deepen their knowledge and expertise with geophysical and remote sensing techniques for archaeology and cultural heritage documentation and management. This survey was carried on two kinds of columns, with circular and rectangular section in order to detect possible hidden defects affecting their integrity. The second survey was carried out at Tempio di Giove, on request of the Soprintendenza Pompei, in order to gain information about the presence of reinforcement structures, which may be put inside the

    The chemical compositions of 42 obsidian pre-Hispanic artifacts from Tancama and Purisima, both archaeological sites of La Sierra Gorda Valleys, Mexico, were analyzed by PIXE technique. These obsidians came from four sources: Sierra de Pachuca Hidalgo, Paraiso Queretaro, Ucareo Michoacan and mainly from Zacualtipan/Metzquititlan Hidalgo. According to archaeological evidences, La Sierra Gorda valleys participated in commercial exchange with other regional sites, from Classic to Post-classic periods (A.D. 300-1500).

    Remote sensing science is increasingly being used to support archaeological and cultural heritage research in various ways. Satellite sensors either passive or active are currently used in a systematic basis to detect buried archaeological remains and to systematic monitor tangible heritage. In addition, airborne and low altitude systems are being used for documentation purposes. Ground surveys using remote sensing tools such as spectroradiometers and ground penetrating radars can detect variations of vegetation and soil respectively, which are linked to the presence of underground archaeological features. Education activities and training of remote sensing archaeology to young people is characterized of highly importance. Specific remote sensing tools relevant for archaeological research can be developed including web tools, small libraries, interactive learning games etc. These tools can be then combined and aligned with archaeology and cultural heritage. This can be achieved by presenting historical and pre-historical records, excavated sites or even artifacts under a "remote sensing" approach. Using such non-form educational approach, the students can be involved, ask, read, and seek to learn more about remote sensing and of course to learn about history. The paper aims to present a modern didactical concept and some examples of practical implementation of remote sensing archaeology in secondary schools in Cyprus. The idea was built upon an ongoing project (ATHENA) focused on the sue of remote sensing for archaeological research in Cyprus. Through H2020 ATHENA project, the Remote Sensing Science and Geo-Environment Research Laboratory at the Cyprus University of Technology (CUT), with the support of the National Research Council of Italy (CNR) and the German Aerospace Centre (DLR) aims to enhance its performance in all these new technologies.

    It is well known that in archaeology large use is done of digital technologies and computer applications for data acquisition, storage, analysis and visualization. The approach of modern archaeology to the study of the evolution of ancient human societies is based on the acquisition and analysis of many types of data. The amount of information coming from the archaeology and the other connected sciences and human ties that need to be stored and made available for analysis are increasing at a very large extent. Such data must, however, be analyzed if they are to become valuable information and knowledge. The data analysis use advanced methods developed in mathematics, informatics, physics, geology, biology, ecology, anthropology and in other natural and human sciences. The inevitable result of this is an exponential increase of the amount and complexity of information that must be acquired, transferred, stored, processed and analyzed. From another, side natural disasters, wars and terrorism created enormous damages to the archaeological heritage and in many case destroyed definitively all information about ancient civilizations. It is urgent a long term project for acquiring, storing and preserving at least the archaeological information. The paper presents the EGEE- II ArchaeoGRID project that, using GRID technologies developed at CERN and in other laboratories, is developing a grid able to fit the very challenging requests of contemporary archaeology.

    The different regulations relative to nuclear energy since the first of January 1999 are given here. Two points deserve to be noticed: the decree of the third august 1999 authorizing the national Agency for the radioactive waste management to install and exploit on the commune of Bures (Meuse) an underground laboratory destined to study the deep geological formations where could be stored the radioactive waste. The second point is about the uranium residues and the waste notion. The judgment of the administrative tribunal of Limoges ( 9. july 1998) forbidding the exploitation of a storage installation of depleted uranium considered as final waste and qualifying it as an industrial waste storage facility has been annulled bu the Court of Appeal. It stipulated that, according to the law number 75663 of the 15. july 1965, no criteria below can be applied to depleted uranium: production residue (possibility of an ulterior enrichment), abandonment of a personal property or simple intention to do it ( future use aimed in the authorization request made in the Prefecture). This judgment has devoted the primacy of the waste notion on this one of final waste. (N.C.)

    The study of ancient remains is more difficult in urban environments than in an archaeological site, because the ancient town and the modern one superpose to each other and precious testimonies are present just under the current irremovable roads and the buildings. However, modern techniques allows to investigate the past under the present, and allows to retrieve information and possibly create a fruition of the ancient site. IBAM-CNR has been engaged for years in this kind of problems, making use of GPR, ERT and other geophysical techniques [1-3], virtual reality [4] and minimally invasive diagnostics [5] in several towns, in particular in southern Italy and Sicily. The valorization of sites in urban areas require precise projects, founding and clear ideas and agreements about the management of the cultural heritage, because only in this case the work performed will be really exploited and enjoyed by specialists and common people. At the conference, some examples will be shown regarding monuments in the town of Lecce, Italy. References [1] M. Pieraccini, L. Noferini, D. Mecatti, C. Atzeni, R. Persico, F.

    Full Text Available Digital documentation and 3D modelling of archaeological sites are important for understanding, definition and recognition of the values of the sites and of the archaeological finds. The most part of archaeological sites are outdoor location, but a cover to preserve the ruins protects often parts of the sites. The possibility to acquire data with different techniques and merge them by using a single reference system allows creating multi-parties models in which 3D representations of the individual objects can be inserted. The paper presents the results of a recent study carried out by Geomatics Laboratory of University of Palermo for the digital documentation and 3D modelling of Eraclea Minoa archaeological site. This site is located near Agrigento, in the south of Sicily (Italy and is one of the most famous ancient Greek colonies of Sicily. The paper presents the results of the integration of different data source to survey the Eraclea Minoa archaeological site. The application of two highly versatile recording systems, the TLS (Terrestrial Laser Scanning and the RPAS (Remotely Piloted Aircraft System, allowed the Eraclea Minoa site to be documented in high resolution and with high accuracy. The integration of the two techniques has demonstrated the possibility to obtain high quality and accurate 3D models in archaeological survey.

    The methodology proposed in this paper in based on an integrated approach for creating a 3D digital reconstruction of an archaeological site, using extensively the 3D documentation of the site in its current state, followed by an iterative interaction between archaeologists and digital modelers, leading to a progressive refinement of the reconstructive hypotheses. The starting point of the method is the reality-based model, which, together with ancient drawings and documents, is used for generating the first reconstructive step. Such rough approximation of a possible architectural structure can be annotated through archaeological considerations that has to be confronted with geometrical constraints, producing a reduction of the reconstructive hypotheses to a limited set, each one to be archaeologically evaluated. This refinement loop on the reconstructive choices is iterated until the result become convincing by both points of view, integrating in the best way all the available sources. The proposed method has been verified on the ruins of five temples in the My Son site, a wide archaeological area located in central Vietnam. The integration of 3D surveyed data and historical documentation has allowed to support a digital reconstruction of not existing architectures, developing their three-dimensional digital models step by step, from rough shapes to highly sophisticate virtual prototypes.

    Full Text Available During the last two decades, since digital technologies have become more sophisticated in acquiring real data and building faithful copies of them, their improvements have suggested interesting applications in the field of valorisation of Historical, Cultural and Artistic Heritage, with significant consequences in the share and widespread of knowledge. But although several technologies and methodologies for 3d digitization have recently been developed and improved, the lack of a standard procedure and the costs connected to their use still doesn't encourage the systematic digital acquisition of wide collections and heritage. The aim of this paper is to show the state of the art of a project whose aim is to provide a methodology and a procedure to create digital reproductions of artefacts for Institutions called to preserve, manage and enhance the fruition of archaeological finds inside museums or through digital exhibitions. Our project’s aim is to find the most suitable procedure to digitally acquire archaeo logical artefacts that usually have small dimensions and have very complex and detailed surfaces. Within our methodology, particular attention has been paid to the use of widely shared and open-source visualization systems that enhance the involvement of the user by emphasizing three-dimensional characteristics of artefacts through virtual reality.

    We report here the first integrated investigation of both ancient DNA and proteins in archaeobotanical samples: medieval grape ( Vitis vinifera L.) seeds, preserved by anoxic waterlogging, from an early medieval (seventh-eighth century A.D.) Byzantine rural settlement in the Salento area (Lecce, Italy) and a late (fourteenth-fifteenth century A.D.) medieval site in York (England). Pyrolysis gas chromatography mass spectrometry documented good carbohydrate preservation, whilst amino acid analysis revealed approximately 90% loss of the original protein content. In the York sample, mass spectrometry-based sequencing identified several degraded ancient peptides. Nuclear microsatellite locus (VVS2, VVMD5, VVMD7, ZAG62 and ZAG79) analysis permitted a tentative comparison of the genetic profiles of both the ancient samples with the modern varieties. The ability to recover microsatellite DNA has potential to improve biomolecular analysis on ancient grape seeds from archaeological contexts. Although the investigation of five microsatellite loci cannot assign the ancient samples to any geographic region or modern cultivar, the results allow speculation that the material from York was not grown locally, whilst the remains from Supersano could represent a trace of contacts with the eastern Mediterranean.

    Previous archaeological mapping work on the successive medieval capitals of the Khmer Empire located at Angkor, in northwest Cambodia (∼9th to 15th centuries in the Common Era, C.E.), has identified it as the largest settlement complex of the preindustrial world, and yet crucial areas have remained unmapped, in particular the ceremonial centers and their surroundings, where dense forest obscures the traces of the civilization that typically remain in evidence in surface topography. Here we describe the use of airborne laser scanning (lidar) technology to create high-precision digital elevation models of the ground surface beneath the vegetation cover. We identify an entire, previously undocumented, formally planned urban landscape into which the major temples such as Angkor Wat were integrated. Beyond these newly identified urban landscapes, the lidar data reveal anthropogenic changes to the landscape on a vast scale and lend further weight to an emerging consensus that infrastructural complexity, unsustainable modes of subsistence, and climate variation were crucial factors in the decline of the classical Khmer civilization.

    Full Text Available In 1985 Gayatri Spivak, criticizing western academic communities, proposed this question that “Can the subaltern speak? “ The answer to this question necessitates the consideration of humanities and any kinds of discourse which bring about subalterns. Postcolonial discourse as a critical, liberal, and anticolonial criticizes this discourse. Postcolonial thinker seeks a period during which an eastern person was defined against a western person. Identification modern subject is the topic that the postcolonial thinker like Michael Foucault questions about while dealing with archaeology. The appearance of a person as an eastern dates back to the time when the existence of the outside world resulted from the subject. An eastern can speak when s/he criticizes the subject based on which the humanities are constructed. Obtaining a definition of human being and the way s/she faces the world in order to understand it, is the primary step of introducing an alternative for authoritative humanities. Postcolonial thinker‘s method in understanding other and the outside world based on intersubjectivity. By establishing human studies instead of western humanities and local humanities and by critical view on spivak’s intellectual paradigm, this method of understanding provides spivak’s question with a positive answer contrary to his own negative answer.

    1981-01-01

    The nuclear microprobe at the Institute of Nuclear Sciences was applied to the measurement of radial concentration profiles of fluorine, in transverse slices of archaeological bone from humans, moas, and other animals. A beam of 2.5 MeV protons was focused to a rectangular spot 250 microns by 50 microns, traversed along a radial line 3mm long, and gamma rays of 5-7 MeV from the reaction 19 F(p, α#betta#) 16 O were detected in a large sodium iodide crystal. Bombardment caused no detectable loss of fluorine from the bone. Measured profiles display a wide variety of shapes and maximum concentrations. In bones which had been exposed to ground water the fluorine concentration usually increases from the centre towards the surface, sometimes by as much as a factor of eight. The concentration at the surface is usually in the range 0.2 to 1%, though in moa bone from a limestone cave it is only 0.025%. Once a quantitative method of analysis has been developed, based on the shape of the profile rather than its magnitude, these profiles might be useful for dating bone. In the meantime, they could be used to distinguish bones of different ages from a common site

    Spatial and temporal distribution of archaeological sites has been shown to associate with several attributes including marine, water, mineral and food resources, climate conditions, geomorphological features, etc. In this study, archeological settlement attributes are evaluated under various associations in order to provide a specialized query platform in a geographic information system (GIS). Towards this end, a spatial database is designed to include a series of archaeological findings for a secluded geographic area of Crete in Greece. The key categories of the geodatabase include the archaeological type (palace, burial site, village, etc.), temporal information of the habitation/usage period (pre Minoan, Minoan, Byzantine, etc.), and the extracted geographical attributes of the sites (distance to sea, altitude, resources, etc.). Most of the related spatial attributes are extracted with readily available GIS tools. Additionally, a series of conceptual data attributes are estimated, including: Temporal relation of an era to a future one in terms of alteration of the archaeological type, topologic relations of various types and attributes, spatial proximity relations between various types. These complex spatiotemporal relational measures reveal new attributes towards better understanding of site selection for prehistoric and/or historic cultures, yet their potential combinations can become numerous. Therefore, after the quantification of the above mentioned attributes, they are classified as of their importance for archaeological site location modeling. Under this new classification scheme, the user may select a geographic area of interest and extract only the important attributes for a specific archaeological type. These extracted attributes may then be queried against the entire spatial database and provide a location map of possible new archaeological sites. This novel type of querying is robust since the user does not have to type a standard SQL query but

    1999-03-01

    Many papers or conference presentations, particularly over the last ten years, have referred to multi-parametric geophysical surveys and integrated interpretations in archaeological prospection. Several experiments of this kind have been undertaken by our laboratory, with mostly fascinating results, but our experience leads us to be rather suspicious of the over-systematic choice of extreme solutions and we would recommend an appropriate and balanced choice, within the limits of the budget available for an operation, between the two following procedures: 1) Routine survey with an extremely large variety of instruments: this allows a better understanding of the underground situation than survey with a single instrument but reduces the area that can be surveyed. A limited number of specific circumstances should lead one to adopt this option. They include: previous knowledge or equally previous ignorance of the targets under investigation, preliminary selection of the most efficient method on a scientific and economic basis, comparative experiments for the validation of new tools, specific detection of targets of different nature into the ground as well as uncertainty about the efficiency of each available method for the actual nature of the investigated site. 2) Survey of a much larger area with only one method, chosen because it is particularly fast and efficient: there is an obvious value in extensive exploration in order to evaluate the size, distribution and limits of a large number of archaeological features. The strict selection of appropriate methods, chosen to meet the aims of a project should consider not only geophysics but all kinds of conventional or non-conventional archaeological methods as well, brought together to permit an integrated interpretation. This highly specialized job does not fall within the normal experience of exploration geophysicists who usually deal with geological features or most field archaeologists who are mainly involved in

    Full Text Available In a context rich in history and cultural heritage, such as the Italian one, promotion and enhancement of historical evidences are crucial. The paper describes the case study of the Archaeological Museum of Parma, which, for the main part, conserves evidences found in the roman archaeological site of Veleia (Piacenza, Italy. To enhance the comprehension of the past, the project aims to promote the exhibits through new digital contents, in particular 3D models and AR applications, to improve their usability by the public. Projects like this pose some difficulties especially in data acquisition and restitution due to complexity of the objects and their dimension and position that are not always adequate for an easy survey. Furthermore, in this case, it was necessary to find a solution that takes into account, on one hand, the necessity of a high degree of detail to ensure high metric quality and, on the other hand, the need of producing small files, in order to easy load and consult them on the web or smartphone applications. For all these reasons, close-range photogrammetry was considered the most adequate technique to produce the major part of the models. In this paper, particular attention will be dedicated to the description of the survey campaign and data processing, underlining difficulties and adopted solutions, in order to provide a methodological summary of the actions performed.

  9. Glycogen synthase kinase 3 has a limited role in cell cycle regulation of cyclin D1 levels.

    The expression level of cyclin D1 plays a vital role in the control of proliferation. This protein is reported to be degraded following phosphorylation by glycogen synthase kinase 3 (GSK3) on Thr-286. We recently showed that phosphorylation of Thr-286 is responsible for a decline in cyclin D1 levels during S phase, an event required for efficient DNA synthesis. These studies were undertaken to test the possibility that phosphorylation by GSK3 is responsible for the S phase specific decline in cyclin D1 levels, and that this event is regulated by the phosphatidylinositol 3-kinase (PI3K)/AKT signaling pathway which controls GSK3. We found, however, that neither PI3K, AKT, GSK3, nor proliferative signaling activity in general is responsible for the S phase decline in cyclin D1 levels. In fact, the activity of these signaling kinases does not vary through the cell cycle of proliferating cells. Moreover, we found that GSK3 activity has little influence over cyclin D1 expression levels during any cell cycle phase. Inhibition of GSK3 activity by siRNA, LiCl, or other chemical inhibitors failed to influence cyclin D1 phosphorylation on Thr-286, even though LiCl efficiently blocked phosphorylation of beta-catenin, a known substrate of GSK3. Likewise, the expression of a constitutively active GSK3 mutant protein failed to influence cyclin D1 phosphorylation or total protein expression level. Because we were unable to identify any proliferative signaling molecule or pathway which is regulated through the cell cycle, or which is able to influence cyclin D1 levels, we conclude that the suppression of cyclin D1 levels during S phase is regulated by cell cycle position rather than signaling activity. We propose that this mechanism guarantees the decline in cyclin D1 levels during each S phase; and that in so doing it reduces the likelihood that simple over expression of cyclin D1 can lead to uncontrolled cell growth.

    Full Text Available A combination of geophysical methods could be very a useful and a practical way of verifying the origin and precise localisation of archaeological situations identified by different remote sensing techniques. The results of different methods (and scales of monitoring these fully non-destructive methods provide distinct data and often complement each other. The presented examples of combinations of these methods/techniques in this study (aerial survey, LIDAR-ALS and surface magnetometer or resistivity survey could provide information on some specifics and may also be limitations in surveying different archaeological terrains, types of archaeological situations and activities. The archaeological site in this contribution is considered to be a material of this study. In case of Neolithic ditch enclosure near Kolín were compared aerial prospection data, magnetometer survey and aerial photo-documentation of excavated site. In the case of hillforts near Levousy we compared LIDAR data with aerial photography and large-scale magnetometer survey. In the case of the medieval castle Liběhrad we compared LIDAR data with geoelectric resistivity measurement. In case of a burial mound cemetery we combined LIDAR data with magnetometer survey. In the case of the production area near Rynartice we combined LIDAR data with magnetometer and resistivity measurements and result of archaeological excavation. Fortunately for successful combination of geophysical and remote sensing results, their conditions and factors for efficient use in archaeology are not the same. On the other hand, the quality and state of many prehistoric, early medieval, medieval and also modern archaeological sites is rapidly changing over time and both groups of techniques represent important support for their comprehensive and precise documentation and protection.

    2007-01-01

    Conflicts of interest between the food industry and public decision makers have increasingly multiplied over the last few years, especially within the context of implementing the French National Nutrition Programme. This paper describes the rhetoric and the strategies developed by the private sector in order to counter the law's implementation and enforcement based on a concrete example, namely, the removal of vending machines from schools. After having evoked possibilities of developing new partnerships as suggested by national and international health authorities, it reaffirms the right and the duty of the State to regulate within the framework of a health promotion policy, an approach which integrates the necessary open democratic public debate between the different sectors.

    Directory of Open Access Journals (Sweden)

    Michael Shanks

    2012-10-01

    Full Text Available The Cotsen Institute in Los Angeles has launched a new publishing initiative in 'Digital Archaeology'. Its first book, Archaeology 2.0: New Approaches to Communication and Collaboration, edited by Eric C. Kansa, Sarah Whitcher Kansa and Ethan Watrall, makes a grand claim, if only in its title, that archaeology has undergone, or is about to undergo, changes that bring about a completely new version or kind of archaeology. The analogy is with the World Wide Web. Just as the IT world embraced radical changes of software design and web delivery nearly ten years ago and announced that this was Web version 2.0, so too archaeology is changed, the authors claim, and enough to warrant the designation version 2.0. We disagree and argue that the claim is not well supported. Moreover, we hold that the book misunderstands the implications of Web 2.0 and its aftermath. The well-meaning authors do make a valuable contribution to debates about uses of information technology in archaeology, and particularly data management. But their perspective is hopelessly narrow, looking back to the circumscribed concerns of professional field archaeologists with their data, its dissemination, use and survival. The authors focus mainly upon their own projects, expressing little interest in the scope of contemporary archaeology, digitally enabled as it all is, through heritage and everything to do with the representation of the material past in the present, an interest surely begged by the overt reference to the global changes associated with the notion of Web 2.0.

    This thesis is an interdisciplinary archaeometric study involving archaeological ceramic material from two large archaeological sites in Central Amazon, namely Lago Grande and Osvaldo, on the confluence region of Negro and Solimoes rivers. It was tested a hypothesis about the existence of an exchange network between the former inhabitants of those sites, focusing on material and/or technological exchange. That hypothesis has implications for archaeological theories of human occupation of the pre-colonial Central Amazon, which try to relativise the role of ecological difficulties of the tropical forest as a limiting factor for the emergence of social complexity in the region. The physical-chemical characterization of potsherds and clay samples near the sites was carried out by: instrumental neutron activation analysis (INAA) to determine the elemental chemical composition; electron paramagnetic resonance (EPR) to determine the firing temperature; X-ray diffraction (XRD) to determine the mineralogical composition; and dating by optically stimulated luminescence (OSL). Previous studies showed that Osvaldo and Lago Grande were occupied by people which produced pottery classified in the Manacapuru and Paredao phases, subclasses of the Incised Rim Tradition, around the 5-10th and 7-12th centuries BC, respectively. INAA results were analyzed by multivariate statistical methods, whereby two chemical groups of pottery were defined for each archaeological site. Significant variation in firing temperatures and mineralogical composition were not identified for such groups. By integration of the results with archaeological data, the superposition between pairs of chemical groups was interpreted as a correlate of an ancient exchange network, although it was not possible to define if it existed exclusively between Lago Grande and Osvaldo. On the contrary, it was suggested that Lago Grande participated in a more extensive exchange network by comparison of two chemical groups

Many of these projects have just begun; consequently the paper does not discuss the results of these investigations, but details their scientific purposes. The investigations cover an area which extends from the Black Sea to northeastern China. The principal objects of these investigations include: the transition from the Late Bronze to the Early Iron Age in the Pontic area north of the Black Sea and the Greek colonization of that area; the activities of the Scythians and the Sassanians in Transcaucasia, urbanism and metallurgy in the Bronze Age of Central Asia; and, finally, cultural developments from the Early Bronze Age to the periods of the Scythians and the Huns period in southern Siberia.

    Este artículo presenta las actividades de la 'Eurasien-Abteilung', del Instituto Arqueológico Alemán, en los distintos países de la ex-URSS. Como muchos de estos proyectos han empezado hace poco tiempo, no pretendemos adelantar resultados, sino planteamientos científicos. El área que abarcan se extiende desde el Mar Negro hasta el Noreste de China. Sus principales temas de investigación son: el cambio del Bronce Final a la primera Edad del Hierro en el norte del Mar Negro, la colonización griega en esta zona, las actividades de los Escitas y de los Sasánidas en Transcaucasia, el urbanismo y la metalurgia de la Edad del Bronce en Asia Central y, finalmente, el desarrollo cultural desde el Bronce Antiguo hasta la época de los Escitas y Hunos en el sur de Siberia.

    One of the main concerns in archaeology is to find of a method to study precisely archaeological structures in the least invasive way possible to avoid damage. The requirement of preserving the structures integrity prevents, in the case of pyramids or tumuli, the study of any internal structure (halls or tombs) which are not reachable by existing corridors. One non-invasive method is the muon tomography. By placing a detector which allows to register the muon direction after the structure, it is possible to have an idea of its composition based on the attenuation of the muon flux, which depends on the material length and density that muons have crossed. This technique, alone or together with other exploration techniques as seismic tomography or electrical resistivity tomography, can provide useful information about the internal structure of the archaeological form that can not be obtained by conventional archaeological methods. In this work, the time measurement necessary to obtain a significant result about the composition of an archaeological structure is estimated. To do that, a Monte Carlo simulation framework based on the MUSIC software, properly tuned for this study, has been developed. The particular case of the Kastas Amfipoli Macedonian tumulus has been considered to perform the simulations.

  16. Archaeological recording and chemical stratigraphy applied to contaminated land studies.

    The method used by archaeologists for excavation and recording of the stratigraphic evidence, within trenches with or without archaeological remains, can potentially be useful to contaminated land consultants (CLCs). The implementation of archaeological practice in contaminated land assessments (CLAs) is not meant to be an exercise in data overkill; neither should it increase costs. Rather, we suggest, that if the excavation and recording, by a trained archaeologist, of the stratigraphy is followed by in-situ chemical characterisation then it is possible that much uncertainty associated with current field sampling practices, may be removed. This is because built into the chemical stratigraphy is the temporal and spatial relationship between different parts of the site reflecting the logic behind the distribution of contamination. An archaeological recording with chemical stratigraphy approach to sampling may possibly provide 'one method fits all' for potentially contaminated land sites (CLSs), just as archaeological characterisation of the stratigraphic record provides 'one method fits all' for all archaeological sites irrespective of period (prehistoric to modern) or type (rural, urban or industrial). We also suggest that there may be practical and financial benefits to be gained by pulling together expertise and resources stemming from different disciplines, not simply at the assessment phase, but also subsequent phases, in contaminated land improvement.

    Full Text Available Sheffield, in the north of England, grew rapidly in the 19th century and gained an international reputation for its cutlery, tableware, and steel products. The material legacy of this age of industrialisation is extensive, and archaeological work in the modern city over the last 20 years has, for the most part, focused on the above and below ground industrial archaeology relating to metals trades' production sites spanning the 19th and 20th centuries. This article describes recent archaeological work around the Upper Chapel, a Unitarian Meeting House in the city centre where archaeological work recovered a possible buried medieval soil deposit, which contained an assemblage of medieval pottery dating from the 12th to 15th centuries. The presence of waster sherds and fragments of kiln furniture within this assemblage suggests that pottery production may have taken place on or near the site, making this the first putative evidence for pottery production in medieval Sheffield. The archaeological investigations also recovered four human burials from the 18th- to 19th-century burial ground associated with the Upper Chapel. The Upper Chapel burial ground differs from other recently excavated cemeteries in Sheffield as it potentially contained graves of high-status individuals, with at least a proportion of the skeletons and coffins well-preserved owing to waterlogged ground conditions. Detailed studies of the human remains, coffins, and incorporated material, including brass shroud pins are also discussed.

    Full Text Available The stalked barnacle Pollicipes pollicipes (Gmelin, 1790 is an important shellfish resource in Portugal. Due to the social-economic importance of barnacle harvesting, a management plan aimed at achieving a controlled and sustainable activity (including temporal and spatial closures, rotational harvesting, a limited number of harvesting licenses, bag and size limits for catches and catch reporting was implemented in 2000 at the Berlengas Nature Reserve (RNB in central Portugal. We evaluated the bag and size limits imposed by the management plan, performing observations on harvesting activity and asking licensed harvesters and RNB staff about these measures. Both inquiries and observations suggest that licensed harvesters are not following the bag and size limits imposed. Mean amounts captured in RNB varied from 14 to 24 kg per harvester/day, but 25% of the observations corresponded to higher catches per individual than the total amount allowed (20 kg. Only half of the sampled amounts (taken in autumn 2005 and 2006 were in agreement with the size limit regulation and 50% of the total biomass comprised individuals of maximal rostro-carinal length (RC ≥ 25 mm. For most harvesters, size limit is the most difficult management rule to fulfil. Both harvesters and RNB staff agree that surveillance is scarce and is a major problem of this fishing activity. In order to achieve a more sustainable use of this resource, we propose the implementation of a more effective surveillance and monitoring plan, the definition of a unique landing site, the maintenance of the bag limit (20 kg and a reduction of the size limit (50% of total biomass comprising individuals ≥ 22 mm RC.

    The cell division cycle of eukaryotes is governed by a complex network of cyclin-dependent protein kinases (CDKs) and auxiliary proteins that govern CDK activities. The control system must function reliably in the context of molecular noise that is inevitable in tiny yeast cells, because mistakes in sequencing cell cycle events are detrimental or fatal to the cell or its progeny. To assess the effects of noise on cell cycle progression requires not only extensive, quantitative, experimental measurements of cellular heterogeneity but also comprehensive, accurate, mathematical models of stochastic fluctuations in the CDK control system. In this paper we provide a stochastic model of the budding yeast cell cycle that accurately accounts for the variable phenotypes of wild-type cells and more than 20 mutant yeast strains simulated in different growth conditions. We specifically tested the role of feedback regulations mediated by G1- and SG2M-phase cyclins to minimize the noise in cell cycle progression. Details of the model are informed and tested by quantitative measurements (by fluorescence in situ hybridization) of the joint distributions of mRNA populations in yeast cells. We use the model to predict the phenotypes of ~30 mutant yeast strains that have not yet been characterized experimentally.

    We applied the seismic refraction method at archaeological site, Tepe Damghani located in Sabzevar, NE of Iran, in order to determine the structures of archaeological interests. This pre-historical site has special conditions with respect to geographical location and geomorphological setting, so it is an urban archaeological site, and in recent years it has been used as an agricultural field. In spring and summer of 2012, the third season of archaeological excavation was carried out. Test trenches of excavations in this site revealed that cultural layers were often disturbed adversely due to human activities such as farming and road construction in recent years. Conditions of archaeological cultural layers in southern and eastern parts of Tepe are slightly better, for instance, in test trench 3×3 m²1S03, third test trench excavated in the southern part of Tepe, an adobe in situ architectural structure was discovered that likely belongs to cultural features of a complex with 5 graves. After conclusion of the third season of archaeological excavation, all of the test trenches were filled with the same soil of excavated test trenches. Seismic refraction method was applied with12 channels of P geophones in three lines with a geophone interval of 0.5 meter and a 1.5 meter distance between profiles on test trench 1S03. The goal of this operation was evaluation of applicability of seismic method in identification of archaeological features, especially adobe wall structures. Processing of seismic data was done with the seismic software, SiesImager. Results were presented in the form of seismic section for every profile, so that identification of adobe wall structures was achieved hardly. This could be due to that adobe wall had been built with the same materials of the natural surrounding earth. Thus, there is a low contrast and it has an inappropriate effect on seismic processing and identifying of archaeological features. Hence the result could be that application of

    The aim of this paper is to investigate the cultural landscape of the archaeological area of Tiwanaku (Bolivia) using multiscale, multispectral and multitemporal satellite data. Geospatial analysis techniques were applied to the satellite data sets in order to enhance and map traces of past human activities and perform a spatial characterization of environmental and cultural patterns. In particular, in the Tiwanaku area, the approach based on local indicators of spatial autocorrelation (LISA) applied to ASTER data allowed us to identify traces of a possible ancient hydrographic network with a clear spatial relation with the well-known moat surrounding the core of the monumental area. The same approach applied to QuickBird data, allowed us to identify numerous traces of archaeological interest, in Mollo Kontu mound, less investigated than the monumental area. Some of these traces were in perfect accordance with the results of independent studies, other were completely unknown. As a whole, the detected features, composing a geometric pattern with roughly North-South orientation, closely match those of the other residential contexts at Tiwanaku. These new insights, captured from multitemporal ASTER and QuickBird data processing, suggested new questions on the ancient landscape and provided important information for planning future field surveys and archaeogeophyical investigations.

No comprehensive research program incorporating both a survey and excavations within a defined geographical or environmental zone has been carried out there since Van der Hoop (1932 conducted his study of the megaliths on the Pasemah plateau in the 1930s. Meanwhile, Van der Hoop’s investigations and several other archaeological research activities at places such as northwest Lampung (McKinnon 1993, Pasemah (Sukendar and Sukidjo 1983-84; Caldwell 1997; Kusumawati and Sukendar 2000, Kerinci (Laporan 1995a, 1996a, and the Minangkabau heartland (Miksic 1986, 1987, 2004 have placed special emphasis on the megalithic remains. As a result, the megaliths are by far the bestknown archaeological attraction of the Sumatran highlands.

  14. A conserved degron containing an amphipathic helix regulates the cholesterol-mediated turnover of human squalene monooxygenase, a rate-limiting enzyme in cholesterol synthesis.

    Cholesterol biosynthesis in the endoplasmic reticulum (ER) is tightly controlled by multiple mechanisms to regulate cellular cholesterol levels. Squalene monooxygenase (SM) is the second rate-limiting enzyme in cholesterol biosynthesis and is regulated both transcriptionally and post-translationally. SM undergoes cholesterol-dependent proteasomal degradation when cholesterol is in excess. The first 100 amino acids of SM (designated SM N100) are necessary for this degradative process and represent the shortest cholesterol-regulated degron identified to date. However, the fundamental intrinsic characteristics of this degron remain unknown. In this study, we performed a series of deletions, point mutations, and domain swaps to identify a 12-residue region (residues Gln-62-Leu-73), required for SM cholesterol-mediated turnover. Molecular dynamics and circular dichroism revealed an amphipathic helix within this 12-residue region. Moreover, 70% of the variation in cholesterol regulation was dependent on the hydrophobicity of this region. Of note, the earliest known Doa10 yeast degron, Deg1, also contains an amphipathic helix and exhibits 42% amino acid similarity with SM N100. Mutating SM residues Phe-35/Ser-37/Leu-65/Ile-69 into alanine, based on the key residues in Deg1, blunted SM cholesterol-mediated turnover. Taken together, our results support a model whereby the amphipathic helix in SM N100 attaches reversibly to the ER membrane depending on cholesterol levels; with excess, the helix is ejected and unravels, exposing a hydrophobic patch, which then serves as a degradation signal. Our findings shed new light on the regulation of a key cholesterol synthesis enzyme, highlighting the conservation of critical degron features from yeast to humans. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Modern society has presented an epic technology development in recent years, driven strongly by communications networks: from micro environments such as personal area networks passing by cell phone to the global Internet network. The communications established in real-time are increasingly, a necessary input. However, the growing demand for communications services and in particularly mobile phone, has meant that the environment is altered by the large number of signals generated by electromagnetic fields that transmit high volumes of energy, which saturate the electromagnetic spectrum, these waves of energy called no ionizing energy. The World Health Organization, through the International Energy Agency Nonionizing (ICNIRP for its acronym in English), has conducted in recent years researches on the effects of the health of people exposed to nonionizing energy; also, have existed proposals regulating these exposure levels. Nonionizing electromagnetic fields are investigated, focusing on transmitting equipment for mobile phone systems in Costa Rica and electromagnetic safety criteria of exposure, both occupational as of general public. The electromagnetism basic concepts and parameters related with nonionizing radiations research are referenced, among them can be mentioned the relationship between the electric field E, the magnetic field H and the power density S. Other concepts such as near-field region, far-field region, exposure zones and specified absorption rate SAR, are also defined. A mathematical fundament is presented showing the relationships between the concepts explained. Guidelines for calculating the power density are provided by means of a theoretical estimate from parameters of transmitting equipment. Also, the procedures for calculating the spatial and temporal averaging are set out and a brief overview is made of epidemiological and biological effects caused by radio frequency radiation. The existing rules at the international level are analyzed to

    Full Text Available The paper is a comment on Alan Williams investigation ‘A Metallurgical Study of some Viking Swords’ published in Gladius XXIX. Williams’ paper comprise metallurgical investigations of 44 Viking Age Swords, all with ULFBERHT inscriptions. Such investigations, made by a well qualified metallurgist, are essential to archaeology. Unfortunately, this one has some serious limitations. In order to give a good description of the quality of a sword-blade, samples showing at least the section through both the edge and the central part of the blade are necessary. This is mostly not the case in Williams’ investigations, and he gives insufficient information about his samples. Other weak points are his group division and his interpretation of the production area for blades containing high-carbon steel.

    Este trabajo es un comentario sobre la investigación de Alan Williams ‘A Metallurgical Study of some Viking Swords` publicado en Gladius XXIX.

Estas investigaciones, realizadas por un arqueometalúrgico altamente cualificado, son esenciales en arqueología. Sin embargo, esta en concreto presenta algunas serias limitaciones. Para poder proporcionar una buena descripción de la calidad de la hoja de una espada, son necesarias muestras de al menos la sección desde el filo y hasta la parte central de la hoja. Este no es el caso de la mayoría de las muestras de Williams, quien proporciona insuficiente información sobre su toma de muestras. Otros puntos débiles son su clasificación en grupos y su interpretación del área de producción para las hojas que contienen un acero con elevado contenido de carbono.

    The main objective of architectural and patrimonial survey is to provide a precise documentation of the status quo of the surveyed objects (monuments, buildings, archaeological object and sites) for preservation and protection, for scientific studies and restoration purposes, for the presentation to the general public. Cultural heritage documentation includes an interdisciplinary approach having as purpose an overall understanding of the object itself and an integration of the information which characterize it. The accuracy and the precision of the model are directly influenced by the quality of the measurements realized on field and by the quality of the software. The software is in the process of continuous development, which brings many improvements. On the other side, compared to aerial photogrammetry, close range photogrammetry and particularly architectural photogrammetry is not limited to vertical photographs with special cameras. The methodology of terrestrial photogrammetry has changed significantly and various photographic acquisitions are widely in use. In this context, the present paper brings forward a comparative study of TLS (Terrestrial Laser Scanner) and digital photogrammetry for 3D modeling. The authors take into account the accuracy of the 3D models obtained, the overall costs involved for each technology and method and the 4th dimension - time. The paper proves its applicability as photogrammetric technologies are nowadays used at a large scale for obtaining the 3D model of cultural heritage objects, efficacious in their assessment and monitoring, thus contributing to historic conservation. Its importance also lies in highlighting the advantages and disadvantages of each method used - very important issue for both the industrial and scientific segment when facing decisions such as in which technology to invest more research and funds.

    2016-01-01

    This article stipulates that vagueness is a socially important yet academically largely overlooked aspect of human interaction with the world. Vagueness and vague experiences can structure material categorisations of the world; it can contribute to the shaping of social relations and nurture...... and ambiguity can be integral to certain social and material phenomena. Third, the article examines recent archaeological analyses of burial practices in South Scandinavian passage graves from the Middle Neolithic in order to discuss the pursuit of certitude in archaeological observations and interpretations...

  19. Obsidian deposits in the central Balkans? Tested against archaeological evidence

    Directory of Open Access Journals (Sweden)

    Tripković Boban

    2003-01-01

    Full Text Available Finds of obsidian artefacts on sites distant from the presumed primary source have often received a romantic note in the history of archaeology manifested in the idea about local exploitation as a form of procurement and archaeologists’ search for as yet undetected deposits of this raw material. In due course, such concepts have found their way into Serbian archaeology as well. The main objective of this contribution, therefore, is to reconsider the current knowledge about obsidian in the central and north Balkans, to test how well founded the idea about the use of local sources is, as well as to indicate some possible directions for future research.

    This article demonstrates the potential of an historical archaeology of smuggling and the value of an interdisciplinary approach to the study of smuggling and its prevention. By exploring the previously unstudied history of the King’s Pipe in Falmouth, a large chimney used for the destruction of tobacco, a rare survivor of many that once existed in England’s port cities, it demonstrates that archaeology could transform our understanding of smuggling and its prevention, and more broadly the history of crime and punishment in eighteenth century England.

    Archaeological bones found close to Mexico city (Tlatelcomila) have been characterized by X-ray Diffraction, Small Angle X-ray Spectroscopy and Scanning Electron Microscopy. These techniques, which are not conventionally used in archaeological research, provided useful information. The boiled bones were clearly distinguished from grilled bones. The degree of deterioration of the bone structure was quantified through parameters such as gyration radius or fractal dimension. The morphology followed the structural modifications and changes resulting from thermic exposure. (Author) 23 refs., 1 tab., 2 figs

    An important point in paleoparasitology is the correct diagnosis of the origin of coprolites found in archaeological sites. The identification of human and animal coprolites, through the study of the shape, size, characteristics after rehydration, alimentary contents, and the presence of parasites, has proved to be accurate for human coprolites. For non-human ones we compared coprolites with recent faeces of animals collected near the archaeological sites, following the methodology above mentioned. In this paper anteaters coprolites (Tamandua tetradactyla; Myrmecophaga tridactyla) with eggs of Gigantorhynchus echinodiscus (Archiancanthocephala; Gigantorynchidae) were identified.

    As commonly used, the term ""megaliths"" refers to huge, free-standing, neolithic stones whose origin and meaning have long been debated by archaeologists and students of prehistory. Perhaps the most famous neolithic site is Stonehenge, the great circle of giant stones on Salisbury Plain in England. Twentieth-century studies of Stonehenge and other megalithic monuments have given rise to the science of astra-archaeology, i.e, the study of early astronomical knowledge through the interpretation of ancient monuments and other archaeological data.The present volume, by a noted British astronomer

  11. Limitations on the concentration of radioactive elements substances (natural or enhanced by human activity) in building materials - a proposal for draft Israeli regulations

    International Nuclear Information System (INIS)

    Schlesinger, T.; Hareuveny, R.; Margaliot, M.

    1997-01-01

    Natural radioactive elements 40 K 228 U and 232 Th and their decay product such as 226 Ra and its short lived daughters occur in building materials in relatively high concentrations. 40 K and part of the above mentioned radionuclides cause external exposure while the inhalation of 222 Ra and its short lived progeny lead to internal exposure of the respiratory tract to alpha particles. In recent years there is a growing tendency to use new construction materials with naturally or technologically enhanced levels of radioactivity (e.g. phosphogypsum, fly ash, exotic minerals etc). This trend causes a growing health concern.The result of this concern is legislation activity and publication of guidance notes by national authorities and international professional organizations related to the radiological implications of these novel technologies. The Ministry of the Environment in Israel is authorized by Israeli legislation to control the exposure of the public to ionising radiation. The ministry asked in 1996 a professional group in the Radiation Protection Division in the Soreq NRC (the authors of this presentation) to study the radiological implications of the use of building materials with naturally or technologically enhanced concentrations of radioactive substances, and to submit draft regulations setting primary limits on excess exposure of the public to ionizing radiation from building materials, and derived limits related to concentrations of specific radionuclides in these materials.The draft regulations will be presented and the way of their derivation will be reviewed (authors)

  12. Different integrated geophysical approaches to investigate archaeological sites in urban and suburban area.

    Piro, Salvatore; Papale, Enrico; Zamuner, Daniela

    2016-04-01

    Geophysical methods are frequently used in archaeological prospection in order to provide detailed information about the presence of structures in the subsurface as well as their position and their geometrical reconstruction, by measuring variations of some physical properties. Often, due to the limited size and depth of an archaeological structure, it may be rather difficult to single out its position and extent because of the generally low signal-to-noise ratio. This problem can be overcome by improving data acquisition, processing techniques and by integrating different geophysical methods. In this work, two sites of archaeological interest, were investigated employing several methods (Ground Penetrating Radar (GPR), Electrical Resistivity Tomography (ERT), Fluxgate Differential Magnetic) to obtain precise and detailed maps of subsurface bodies. The first site, situated in a suburban area between Itri and Fondi, in the Aurunci Natural Regional Park (Central Italy), is characterized by the presence of remains of past human activity dating from the third century B.C. The second site, is instead situated in an urban area in the city of Rome (Basilica di Santa Balbina), where historical evidence is also present. The methods employed, allowed to determine the position and the geometry of some structures in the subsurface related to this past human activity. To have a better understanding of the subsurface, we then performed a qualitative and quantitative integration of this data, which consists in fusing the data from all the methods used, to have a complete visualization of the investigated area. Qualitative integration consists in graphically overlaying the maps obtained by the single methods; this method yields only images, not new data that may be subsequently analyzed. Quantitative integration is instead performed by mathematical and statistical solutions, which allows to have a more accurate reconstruction of the subsurface and generates new data with high

    As a method with high resolution, GPR has been extensively used in archaeological surveys. However, conventional GPR profile can only provide limited geometry information, such as the shape or location of the interface, but can't give the distribution of physical properties which could help identify the historical remains more directly. A common way for GPR to map parameter distribution is the common-midpoint velocity analysis, but it provides limited resolution. Another research hotspot, the full-waveform inversion, is unstable and relatively dependent on the initial model. Coring method could give direct information in drilling site, while the accurate result is only limited in several boreholes. In this paper, we propose a new scheme to enhance imaging and characterization of archaeological targets by fusion of GPR and coring data. The scheme mainly involves the impedance inversion of conventional common-offset GPR data, which uses well log to compensate GPR data and finally obtains a high-resolution estimation of permittivity. The core analysis result also contributes to interpretation of the inversion result. To test this method, we did a case study at Mudu city site in Suzhou, China. The results provide clear images of the ancient city's moat and wall subsurface and improve the characterization of archaeological targets. It is shown that this method is effective and feasible for archaeological exploration.

  14. Immediate Realities: an anthropology of computer visualisation in archaeology

    Directory of Open Access Journals (Sweden)

    Jonathan Bateman

    2000-06-01

    Full Text Available The use of computer visualisation techniques is an increasing part of archaeology's illustrative repertoire - but how do these images relate to the wider visual language that archaeologists use? This article assesses computer visualisations in the light of a range of anthropological, art historical, and cultural critiques to place them and their production squarely within the broader spectrum of the discipline's output. Moving from identifying the shortcomings in the methods and scope of existing critiques of archaeological illustrations, a comprehensive approach to understanding the visual culture of archaeology is outlined. This approach is specifically applied to computer visualisations, and identifies both the sociology of their production, and the technological nature of their creation and reproduction as key elements influencing their readings as communicators of archaeological ideas. In order to develop useful understandings of how the visual languages we employ act within the discourse of the discipline, we must be inclusive in our critiques of those languages. Until we consider the cultural products of our discipline with the same sophistication with which we examine the products of other cultures (past and present, we will struggle to use them to their full potential.

  17. Strategies for Teaching Maritime Archaeology in the Twenty First Century

    Science.gov (United States)

    Staniforth, Mark

    2008-12-01

    Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.

    2016-04-01

    Accurate maps of past land use are necessary for studying the impact of anthropogenic land-cover changes on climate and biodiversity. We develop a Bayesian hierarchical model to reconstruct the land use using Gaussian Markov random fields. The model uses two observations sets: 1) archaeological data, representing human settlements, urbanization and agricultural findings; and 2) pollen-based land estimates of the three land-cover types Coniferous forest, Broadleaved forest and Unforested/Open land. The pollen based estimates are obtained from the REVEALS model, based on pollen counts from lakes and bogs. Our developed model uses the sparse pollen-based estimations to reconstruct the spatial continuous cover of three land cover types. Using the open-land component and the archaeological data, the extent of land-use is reconstructed. The model is applied on three time periods - centred around 1900 CE, 1000 and, 4000 BCE over Sweden for which both pollen-based estimates and archaeological data are available. To estimate the model parameters and land use, a block updated Markov chain Monte Carlo (MCMC) algorithm is applied. Using the MCMC posterior samples uncertainties in land-use predictions are computed. Due to lack of good historic land use data, model results are evaluated by cross-validation. Keywords. Spatial reconstruction, Gaussian Markov random field, Fossil pollen records, Archaeological data, Human land-use, Prediction uncertainty

    The book that now is presented is formed by twelve articles that approach from different perspective topics as the archaeological prospecting, the analysis of the pre hispanic and colonial ceramic, the obsidian and the mural painting, besides dating and questions about the data ordaining. Following the chronological order in which the exploration techniques and laboratory studies are required, there are presented in the first place the texts about the systematic and detailed study of the archaeological sites, later we pass to relative topics to the application of diverse nuclear techniques as PIXE, RBS, XRD, NAA, SEM, Moessbauer spectroscopy and other conventional techniques. The multidisciplinary is an aspect that highlights in this work, that which owes to the great specialization of the work that is presented even in the archaeological studies including in the open ground of the topography, mapping, excavation and, of course, in the laboratory tests. Most of the articles are the result of several years of investigation and it has been consigned in the responsibility of each article. The texts here gathered emphasize the technical aspects of each investigation, the modern compute systems applied to the prospecting and the archaeological mapping, the chemical and physical analysis of organic materials, of metal artifacts, of diverse rocks used in the pre hispanic epoch, of mural and ceramic paintings, characteristics that justly underline the potential of the collective works.

    Full Text Available The study and the protection of Cultural Heritage in recent years have undergone a revolution about the search tools and the reference disciplines. The technological approach to the problem of the collection, organization and publication of archaeological data using GIS software has completely changed the essence of the traditional methods of investigation, paving the way to the development of several application areas, up to the Cultural Resource Management. A relatively recent specific sector of development for archaeological GIS development sector is dedicated to the intra - site analyses aimed to recording, processing and display information obtained during the excavations. The case - study of the archaeological site located in the south - east of San Pietro Vetere plateau in Aquino, in the Southern Lazio, is concerned with the illustration of a procedure describing the complete digital workflow relative to an intra-site analysis of an archaeological dig. The GIS project implementation and its publication on the web, thanks to several softwares, particularly the FOSS (Free Open Source Software Quantum - GIS, are an opportunity to reflect on the strengths and the critical nature of this particular application of the GIS technology. For future developments in research it is of fundamental importance the identification of a digital protocol for processing of excavations (from the acquisition, cataloguing, up data insertion, also on account of a possible future Open Project on medieval Aquino.

    Full Text Available From early discussions of the disruptive potential of computer technologies for archaeological applications, to the present era of digital archaeology as the technical underpinning of modern archaeological practice, we have continued to debate the potential impacts of digital communication and digital capture and storage on our knowledge, profession and communications. The increased use of digital tools and methods for archaeological research and dissemination, as well as what Roosevelt (2015 has referred to as the shift to the digital paradigm within archaeological practice, leads us to suggest that the impact of this paradigm shift requires careful and critical examination. This article will examine the edges of the disciplines of archaeology and sociology, where we aim to advance our understanding of the relationship between digital technologies and archaeological knowledge from a uniquely social perspective, using the theoretical approaches of both classic and modern sociologists. The application of this lens of sociology to digital archaeology equips us to understand how archaeology and archaeological practice is situated in a social world, which is especially relevant in the Global West, where digital technology is ubiquitous. Through a critical consideration of the complexity of use of digital technologies within digital archaeology, we can begin to shift our focus away from the character and method of tools and workflow, to the background of intellectual power and influence.

    . The inherent limitation of employing ERT in a conductive environment is counterbalanced by the incorporation of precise knowledge for the conductivity and bathymetry of the saline water in the modelling and inversion procedure. Although the methodology definitely needs further refinement, the overall outcomes of this work underline the potential of ERT imaging being integrated into wider shallow marine projects for the mapping of archaeological sites in similar environmental regimes.

  19. Early Pleistocene archaeological occurrences at the Feiliang site, and the archaeology of human origins in the Nihewan Basin, North China.

    Full Text Available The Early Pleistocene archaeological evidence from the fluvio-lacustrine sequence of the Nihewan Basin (North China offers an excellent opportunity to explore early human evolution and behavior in a temperate setting in East Asia, following the earliest 'Out of Africa'. Here we present the first comprehensive study of the Feiliang (FL site, with emphasis on the archaeological sequence, site integrity, and stone artifact assemblages. Magnetostratigraphic dating results show that early humans occupied the site ca. 1.2 Ma. Archaeological deposits were buried rapidly in primary context within shallow lake margin deposits, with only minor post-depositional disturbance from relatively low energy hydraulic forces. The FL lithic assemblage is characterized by a core and flake, Oldowan-like or Mode 1 technology, with a low degree of standardization, expedient knapping techniques, and casually retouched flakes. The bone assemblage suggests that hominin occupation of the FL site was in an open habitat of temperate grassland with areas of steppe and water. The main features of the FL assemblage are discussed in the context of the early Pleistocene archaeology of Nihewan, for which an assessment of current and future research is also presented.

    Closure caps for low-level radioactive waste disposal facilities are typically designed as layered earthen structures, the composition of which is intended to prevent the infiltration of water and the intrusion of the public into waste forms. Federal regulations require that closure caps perform these functions well enough that minimum exposure guidelines will be met for at least 500 years. Short-term experimentation cannot mimic the conditions that will affect closure caps on the scale of centuries, and therefore cannot provide data on the performance of cap designs over long periods of time. Archaeological mounds hundreds to thousands of years old which are closely analogous to closure caps in form, construction details, and intent can be studied to obtain the necessary understanding of design performance. Pacific Northwest Laboratory conducted a review and analysis of archaeological literature on ancient human-made mounds to determine the quality and potential applicability of this information base to assessments of waste facility design performance. A bibliography of over 200 English-language references was assembled on mound structures from the Americas, Europe, and Asia. A sample of these texts was read for data on variables including environmental and geographic setting, condition, design features, construction. Detailed information was obtained on all variables except those relating to physical and hydrological characteristics of the mound matrix, which few texts presented. It is concluded that an extensive amount of literature and data are available on structures closely analogous to closure caps and that this information is a valuable source of data on the long-term performance of mounded structures. Additional study is recommended, including an expanded analysis of design features reported in the literature and field studies of the physical and hydraulic characteristics of different mound designs. 23 refs., 10 figs., 12 tabs.

    Over the past three years the 2010 in Vienna founded Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology (http://archpro.lbg.ac.at), in collaboration with its ten European partner organizations, has made considerable progress in the development and application of near-surface geophysical survey technology and methodology mapping square kilometres rather than hectares in unprecedented spatial resolution. The use of multiple novel motorized multichannel GPR and magnetometer systems (both Förster/Fluxgate and Cesium type) in combination with advanced and centimetre precise positioning systems (robotic totalstations and Realtime Kinematic GPS) permitting efficient navigation in open fields have resulted in comprehensive blanket coverage archaeological prospection surveys of important cultural heritage sites, such as the landscape surrounding Stonehenge in the framework of the Stonehenge Hidden Landscape Project, the mapping of the World Cultural Heritage site Birka-Hovgården in Sweden, or the detailed investigation of the Roman urban landscape of Carnuntum near Vienna. Efficient state-of-the-art archaeological prospection survey solutions require adequate fieldwork methodologies and appropriate data processing tools for timely quality control of the data in the field and large-scale data visualisations after arrival back in the office. The processed and optimized visualisations of the geophysical measurement data provide the basis for subsequent archaeological interpretation. Integration of the high-resolution geophysical prospection data with remote sensing data acquired through aerial photography, airborne laser- and hyperspectral-scanning, terrestrial laser-scanning or detailed digital terrain models derived through photogrammetric methods permits improved understanding and spatial analysis as well as the preparation of comprehensible presentations for the stakeholders (scientific community, cultural heritage managers, public).

    Full Text Available As an orchestra or a rock star, archaeologists have their audience too. This paper wants to highlight an integrated approach between fieldwork, its account and its dissemination to the public in different ways, including social media. This potential integration has come to life in the 2011 excavation of the Roman mansio of Vignale (Italy and it has been named “Excava(ction”. It doesn’t mean a new way of digging but another way of approaching the excavation, an approach integrated toward and with the public, both on site and on the social Web. “Excava(ction” conceives the site as a stage and digging as a performance, through a continuous dialogue between archaeologists and the public. Archaeologists share their work in the form of guided tours (live, theatrical-like performances, communicative diaries and videos (edited, motion-picture performances and on a blog (www.uominiecoseavignale.it. They receive back comments and oral accounts from the local community about the main themes of common interest. “Excava(ction” means engagement both of archaeologists and the public in the pursuit of a global multivocality during archaeological excavation.

  4. The principles, procedures and pitfalls in identifying archaeological and historical wood samples.

    2015-07-01

    The science of wood anatomy has evolved in recent decades to add archaeological and historical wood to its repertoire of documenting and characterizing modern and fossil woods. The increasing use of online wood anatomy databases and atlases has fostered the adoption of an international consensus regarding terminology, largely through the work of the International Association of Wood Anatomists (IAWA). This review presents an overview for the general reader of the current state of principles and procedures involved in the study of the wood anatomy of archaeological and historical specimens, some of which may be preserved through charring, waterlogging, desiccation or mineral replacement. By means of selected case studies, the review evaluates to what extent varying preservation of wood anatomical characteristics limits the level of identification to taxon. It assesses the role played by increasingly accessible scanning electron microscopes and complex optical microscopes, and whether these, on the one hand, provide exceptional opportunities for high-quality imaging and analysis of difficult samples, but, on the other hand, might be misleading the novice into thinking that advanced technology can be a substitute for specialized botanical training in wood anatomy. © The Author 2015.

    Full Text Available Differing terminology and database structure hinders meaningful cross search of excavation datasets. Matching free text grey literature reports with datasets poses yet more challenges. Conventional search techniques are unable to cross search between archaeological datasets and Web-based grey literature. Results are reported from two AHRC funded research projects that investigated the use of semantic techniques to link digital archive databases, vocabularies and associated grey literature. STAR (Semantic Technologies for Archaeological Resources was a collaboration between the University of Glamorgan, Hypermedia Research Unit and English Heritage (EH. The main outcome is a research Demonstrator (available online, which cross searches over excavation datasets from different database schemas, including Raunds Roman, Raunds Prehistoric, Museum of London, Silchester Roman and Stanwick sampling. The system additionally cross searches over an extract of excavation reports from the OASIS index of grey literature, operated by the Archaeology Data Service (ADS. A conceptual framework provided by the CIDOC Conceptual Reference Model (CRM integrates the different database structures and the metadata automatically generated from the OASIS reports by natural language processing techniques. The methods employed for extracting semantic RDF representations from the datasets and the information extraction from grey literature are described. The STELLAR project provides freely available tools to reduce the costs of mapping and extracting data to semantic search systems such as the Demonstrator and to linked data representation generally. Detailed use scenarios (and a screen capture video provide a basis for a discussion of key issues, including cost-benefits, ontology modelling, mapping, terminology control, semantic implementation and information extraction issues. The scenarios show that semantic interoperability can be achieved by mapping and extracting

This case study clearly illustrates the benefit of using multiple geophysical methods in archaeological studies. It further illustrates the advantage of 3-D GPR surveying at sites where anthropogenic disturbances (such as metallic pipes and other utilities) might limit the applicability of commonly applied mapping techniques such as magnetic gradiometry or EM38 conductivity mapping.

    Full Text Available The Cambridge Illustrated History of Archaeology is another in a series of volumes devoted to the history of archaeology that have appeared in recent time. Paul Bahn, the editor of the volume, has broken down his coverage of the history of worldwide archaeology into the following arrangement 'The Archaeology of Archaeology", "Old Worlds and New, 1500-1760", "Antiquarians and Explorers, 1760-1820", "Science and Romanticism, 1820-1860", "The Search for Human Origins, 1860-1920", "Archaeology Comes of Age, 1920-1960", "New Techniques and Competing Philosophies, 1960-1990",and "Current Controversies and Future Trends". Bahn's volume explores many of the major developments in archaeological practice from both in the classical world and was as from the practice of archaeology in the Americas. The volume even gives the reader a glimpse into the origins and growth of archaeology in New Zealand. Of particular interest is coverage of the history of early archaeological efforts having to do with early studies of human origins.

    Archaeological objects were borrowed from Arges County History Museum (ACHM) and investigated at the Institute for Nuclear Research (INR). Metallic objects made in iron, copper alloys and silver discovered in southern part of Romania, mostly Dacian and Roman origin, were investigated. For imaging was used the neutron and gamma imaging facility from tangential channel of the TRIGA ACPR to put in evidence the internal structure of the objects. For elemental and chemical composition, concentration levels in objects were performed investigations by X-ray fluorescence (XRF) and X-ray diffraction (XRD). These investigations offer valuable information in archaeological research about composition, structure of the bulk, presence of alteration, inclusions, typology of the location of material extraction, manufacturing techniques etc. This work is an example of application of neutron imaging and other radiation-based analytical methods for cultural heritage research that had the aim to involve some of the non-destructive investigation methods available at INR.

    Full Text Available Cultural Heritage scientists need methodologies to examine Art and Archaeology in order to understand artistic materials and techniques and devise better conservation procedures. This review discusses the most successful and promising applications of Terahertz (THz technology in Cultural Heritage Science. THz is used in homeland security and for plenty of other industrial sectors and it presents a number of valuable features specifically for the investigation of Art and Archaeology: No radiation risk, low power, non-contact and reflection mode. Recent technical advancements are also making its application fast, mobile and relatively affordable creating a potential for its diffused implementation in museums. While THz is most promising for the investigation of multilayered art, such as paintings, it has been tested on a very large range of artifacts, from manuscripts to mummies and lacquered historical furniture.

    Full Text Available This paper presents an overview of major trends in archaeological network research through a bibliometric analysis of the full corpus of publications on the topic between 1965 and 2016. It illustrates we can begin identifying the outlines of a new sub-discipline within archaeology with its distinct traditions, including a diversity of research approaches, dedicated events and preferred publication venues. This sub-discipline is at a similar stage of development as historical network research, and we argue that archaeologists and historians alike interested in establishing network research as a key tool for exploring social change will have a greater chance for success to the extent that we actively collaborate, pool resources, engage in common community activities and publications, and learn from each other’s mistakes.

    This study is aimed at an assessment of the methodologies, instruments and new applications for underwater archaeology. Research focused on study of the various kinds of degradation affecting underwater finds and stone materials aged in underwater environment, efficiency evaluation of various surface cleaning methods and study and mixing of protective products with consolidating resins and antimicrobial biocides to be applied to restored underwater finds. Transmitted light optical microscopy and scanning electron microscopy (SEM) were used to study surface biofilms and the interactions with samples of different stone materials such as brick, marble and granite immersed in the submarine archaeological area of Crotone (South of Italy). Surface cleaning tests were performed with application of ion exchange resins, EDTA, hydrogen peroxide and ultrasound techniques. Capillary water absorption, simulated solar ageing and colourimetric measurements were carried out to evaluate hydrophobic and consolidant properties; to assess biocidal efficacy, heterotrophic micro-organisms ( Aspergillus niger) were inoculated on agar plates and growth inhibition was measured.

    Bishop, Ronald L.

    2001-01-01

    Application of instrumental neutron activation analysis to the study of archaeological ceramics involves the determination of the source or sources used to produce pottery. Groups of relatively homogeneous elemental abundances are shown to be statically distinct from one another often leading to the assesment of what was locally produced and what was imported to a site. These assesment, however are among the most preliminary interpretations. Archaeology is concerned with the reasons for artificial distributions and how and why the distribution varied through time 3 reasons that include the social and political basis of ancient economics and how these responded to other factors, such as ideology. These objectives are addressed through the increasing refinement of compositional groups leading toward greater specificity of attribution. In so doing the role of analytical precision among other considerations groves in importance. This paper illustration some of these considerations with examples from the U.S. southwest, the Maya region of southern mexico, and lower central America

    Full Text Available Over the last decades, especially among the postprocessualy oriented archaeologists, the link between the research into the past and various relations of domination in the modern world has been explicitly articulated, as well as the ways in which the discipline engages in the dialogue with its social context, widely encompassed by the notion of the public. On the other hand, the eminent representatives of other theoretical approaches in archaeology, such as Gordon Childe, have argued for the purpose of archaeological research in the search for knowledge leading to more just and human society much before this clearly value-oriented proclamation. The message conveyed by archaeologists to the public depends on the choice of the segment of this wide notion and whose interests an individual researcher decides to enforce, regardless of the theoretical and methodological inclinations.

Based on these results, the archaeologists of the Carinthian museum started digging campaigns in the most interesting areas, verifying the geophysical results. Up to now part of the apsis had been digged out. Photos of these fundaments will be shown. The digging results show good agreement with the geophysical results. Geoelectric mapping gives excellent results, but is rather time consuming - therefore specific parts had been mapped using the faster EM method in a continuous registration mode - either by walking along lines and the setting of marker points or by coupling the instrument with an precise GPS system and using a random walk strategy. The achievable resolution to the archaeological objects in comparison to the other geophysical methods had been analysed.

    This paper presents results from different fusion techniques between geophysical images from different modalities in order to combine them into one image with higher information content than the two original images independently. The resultant image will be useful for the detection and mapping of buried archaeological relics. The examined archaeological area is situated in Kampana site (NE Greece) near the ancient theater of Maronia city. Archaeological excavations revealed an ancient theater, an aristocratic house and the temple of the ancient Greek God Dionysus. Numerous ceramic objects found in the broader area indicated the probability of the existence of buried urban structure. In order to accurately locate and map the latter, geophysical measurements performed with the use of the magnetic method (vertical gradient of the magnetic field) and of the electrical method (apparent resistivity). We performed a semi-stochastic pixel based registration method between the geophysical images in order to fine register them by correcting their local spatial offsets produced by the use of hand held devices. After this procedure we applied to the registered images three different fusion approaches. Image fusion is a relatively new technique that not only allows integration of different information sources, but also takes advantage of the spatial and spectral resolution as well as the orientation characteristics of each image. We have used three different fusion techniques, fusion with mean values, with wavelets by enhancing selected frequency bands and curvelets giving emphasis at specific bands and angles (according the expecting orientation of the relics). In all three cases the fused images gave significantly better results than each of the original geophysical images separately. The comparison of the results of the three different approaches showed that the fusion with the use of curvelets, giving emphasis at the features' orientation, seems to give the best fused image

    This contribution deals with some fields of archaeometry, i.e. the application of physical methods in archaeology: Age determination in glasses and potsherds with the aid of fission tracks and thermoluminescence, determination of the origin of coins and pottery by chemical analyses with the aid of neutron activation ('fingerprinting'), obtaining information on metal winning in ancient history with the aid of the C-14-method.

  7. Unguja Ukuu on Zanzibar : An archaeological study of early urbanism

    OpenAIRE

    Juma, Abdurahman

    2004-01-01

    This study describes archaeological excavations carried out at Unguja Ukuu on the main island of Zanzibar, Tanzania. The site has long remained obscure, oral histories do not mention it and no particular group among the living community of the island describes its origin from the site. A stone well at Unguja Ukuu together with several other early monuments of the east African coast that survive on the site have been attributed to the Wadebuli, suspected by early scholars to be people of Arab ...

  8. The development of Spanish archaeology in the 20th century

    OpenAIRE

    Martínez Navarrete, María Isabel

    1997-01-01

    The long history of state unity and archaeology’s strong dependence on the state explain how archaeological practice became institutionalized in Spain. The intellectual currents that marked Spanish archaeology’s development – antiquarianism, Enlightenment interest in human antiquity, the definition of national identity – are analogous to those in other European countries: foreign models always were influential. Largely due to traditional, institutionalized links to German and French archaeolo...

    2013-12-01

    This paper explores the close links between botany and archaeology, using case studies from the ancient Mediterranean. It explains the kinds of palaeobotanical remains that archaeologists can recover and the methods used to analyse them. The importance of iconographic and textual evidence is also underlined. Examples of key research areas that focus on ancient plants are discussed: diet and palaeoeconomy; medicines, poisons, and psychotropics; perfumes, cosmetics, and dyes; and prestige.

  10. The Archaeology of Wari and the Dispersal of Quechua

    OpenAIRE

    The association of Wari with Quechua, or proto-Quechan speech, cannot be demonstrated by an unbroken tradition of material culture such as ceramic style from the Middle Horizon to ethnohistorically known Quechua speaking communities. However, the spread of Wari from its northern Ayacucho homeland, to the archaeologically most obvious colonies that stretch across Andes from Cuzco to southern Ayacucho, and into Ica and Arequipa, corresponds remarkably with the ethnohistoric distribution of Quec...

    Despite the emergence of stereotactic body radiotherapy (SBRT) for treatment of medically inoperable early-stage non-small-cell lung cancer patients, the molecular effects of focal exposure of limited lung volumes to high-dose radiation have not been fully characterized. This study was designed to identify molecular changes induced by focal high-dose irradiation using a mouse model of SBRT. Central areas of the mouse left lung were focally-irradiated (3 mm in diameter) with a single high-dose of radiation (90 Gy). Temporal changes in gene expression in the irradiated and non-irradiated neighboring lung regions were analyzed by microarray. For comparison, the long-term effect (12 months) of 20 Gy radiation on a diffuse region of lung was also measured. The majority of genes were down-regulated in the focally-irradiated lung areas at 2 to 3 weeks after irradiation. This pattern of gene expression was clearly different than gene expression in the diffuse region of lungs exposed to low-dose radiation. Ontological and pathway analyses indicated these down-regulated genes were mainly associated with organ development. Although the number was small, genes that were up-regulated after focal irradiation were associated with immune-related functions. The temporal patterns of gene expression and the associated biological functions were also similar in non-irradiated neighboring lung regions, although statistical significance was greatly reduced when compared with those from focally-irradiated areas of the lung. From network analysis of temporally regulated genes, we identified inter-related modules associated with diverse functions, including organ development and the immune response, in both the focally-irradiated regions and non-irradiated neighboring lung regions. Focal exposure of lung tissue to high-dose radiation induced expression of genes associated with organ development and the immune response. This pattern of gene expression was also observed in non

    Full Text Available This study evaluates the efficiency of iron-based oxy-hydroxides to remove antimony from groundwater to meet the requirements of drinking water regulations. Results obtained by batch adsorption experiments indicated that the qualified iron oxy-hydroxide (FeOOH, synthesized at pH 4 for maintaining a high positive charge density (2.5 mmol OH−/g achieved a residual concentration of Sb(III below the EU drinking water regulation limit of 5 μg/L by providing an adsorption capacity of 3.1 mg/g. This is more than twice greater compared either to similar commercial FeOOHs (GFH, Bayoxide or to tetravalent manganese feroxyhyte (Fe-MnOOH adsorbents. In contrast, all tested adsorbents failed to achieve a residual concentration below 5 μg/L for Sb(V. The higher efficiency of the qualified FeOOH was confirmed by rapid small-scale column tests, since an adsorption capacity of 3 mg Sb(III/g was determined at a breakthrough concentration of 5 μg/L. However, it completely failed to achieve Sb(V concentrations below 5 μg/L even at the beginning of the column experiments. The results of leaching tests classified the spent qualified FeOOH to inert wastes. Considering the rapid kinetics of this process (i.e., 85% of total removal was performed within 10 min, the developed qualified adsorbent may be promoted as a prospective material for point-of-use Sb(III removal from water in vulnerable communities, since the adsorbent’s cost was estimated to be close to 30 ± 3.4 €/103 m3 for every 10 μg Sb(III/L removed.

    2010-01-01

    The interaction of diverse areas as the analytic chemistry, the history of the art and the archaeology has allowed the development of a variety of techniques used in archaeology, in conservation and restoration. These methods have been used to date objects, to determine the origin of the old materials and to reconstruct their use and to identify the degradation processes that affect the integrity of the art works. The objective of this chapter is to offer a general vision on the researches that have been realized in the Instituto Nacional de Investigaciones Nucleares (ININ) in the field of cultural goods. A series of researches carried out in collaboration with national investigators and of the foreigner is described shortly, as well as with the great support of degree students and master in archaeology of the National School of Anthropology and History, since one of the goals that have is to diffuse the knowledge of the existence of these techniques among the young archaeologists, so that they have a wider vision of what they could use in an in mediate future and they can check hypothesis with scientific methods.

    Numerous eggs of capillariid nematodes have been found in coprolites from a wide range of hosts and in raptor pellets in archaeological samples from Patagonia. The structure and sculpture of the eggshell of these nematodes and their biometry are commonly used for identification. The aim of this study was to determine whether eggs of the genus Calodium with similar morphology, found in different archaeological samples from Patagonia, belong to the same species. For this purpose, capillariid eggs (N= 843) with thick walls and radial striations were studied by permutational multivariate analysis of variance (PERMANOVA). Eggs exhibiting similar shape and structure also showed similar biometry, regardless of the zoological origin of coprolites (P= 0.84), host diet (P= 0.19), character of the archaeological sites (P= 0.67) and chronology (P= 0.66). Thus, they were attributed to the same species. We suggest that an unidentified zoonotic species of the genus Calodium occurred in the digestive tract of a wide range of hosts in Patagonia during the Holocene and that both human and animal populations were exposed to this parasite during the Holocene in the study area.

    Characterization of ceramic fragments is a very important area of research in art and archeometry area because it enables a greater understanding of how ancient civilizations behave and what were their traditions and customs. Petrography and chemical analyses are commonly used, but these techniques are destructive, which is not interesting for this type of sample. Through the exchange of multidisciplinary scientific knowledge and new partnerships, high resolution X-ray microtomography has been introduced in archaeological area as a great possibility of 3D inspection in a non-destructive way. The goal of this work is to investigate the internal microstructures of four samples of archeological ceramic, from the Archaeological Site of Macacu - RJ. The X-ray microtomography were performed in a high resolution setup, and can be used to infer the nature of organic temper even with all plant remains completely burnt out during the firing process and also to ensure the homogeneity of samples envisaged for geochemical analyses, especially with respect to the distribution of chemically diverse fabric compounds. In this way this study intends to contribute to our understanding of the archaeological and historical formations of this region. (author)

    Wiley, Bridgette; Schulze, Jürgen P.

    2015-03-01

    We present an application for Android phones or tablets called "archAR" that uses augmented reality as an alternative, portable way of viewing archaeological information from UCSD's Levantine Archaeology Laboratory. archAR provides a unique experience of flying through an archaeological dig site in the Levantine area and exploring the artifacts uncovered there. Using a Google Nexus tablet and Qualcomm's Vuforia API, we use an image target as a map and overlay a three-dimensional model of the dig site onto it, augmenting reality such that we are able to interact with the plotted artifacts. The user can physically move the Android device around the image target and see the dig site model from any perspective. The user can also move the device closer to the model in order to "zoom" into the view of a particular section of the model and its associated artifacts. This is especially useful, as the dig site model and the collection of artifacts are very detailed. The artifacts are plotted as points, colored by type. The user can touch the virtual points to trigger a popup information window that contains details of the artifact, such as photographs, material descriptions, and more.

    2017-03-01

    Full Text Available Research e-infrastructures, digital archives and data services have become important pillars of scientific enterprise that in recent decades has become ever more collaborative, distributed and data-intensive. The archaeological research community has been an early adopter of digital tools for data acquisition, organisation, analysis and presentation of research results of individual projects. However, the provision of e-infrastructure and services for data sharing, discovery, access and re-use has lagged behind. This situation is being addressed by ARIADNE: the Advanced Research Infrastructure for Archaeological Dataset Networking in Europe. This EU-funded network has developed an e-infrastructure that enables data providers to register and provide access to their resources (datasets, collections through the ARIADNE data portal, facilitating discovery, access and other services across the integrated resources. This article describes the current landscape of data repositories and services for archaeologists in Europe, and the issues that make interoperability between them difficult to realise. The results of the ARIADNE surveys on users' expectations and requirements are also presented. The main section of the article describes the architecture of the e-infrastructure, core services (data registration, discovery and access and various other extant or experimental services. The on-going evaluation of the data integration and services is also discussed. Finally, the article summarises lessons learned, and outlines the prospects for the wider engagement of the archaeological research community in sharing data through ARIADNE.

    2006-07-15

    The aim of this review is to combine the almost universal fascination we share for our past with the comparatively recent, in archaeological terms, application of geophysical prospection methods. For their success, each of these methods relies upon a physical contrast to exist between the buried archaeological feature and the properties of the surrounding subsoil. Understanding the archaeological origin of such physical contrasts, in terms of density, thermal conductivity, electrical resistance, magnetic or dielectric properties, remains fundamental to an appreciation of the discipline. This review provides a broad introduction to the subject area acknowledging the historical development of the discipline and discusses each of the major techniques in turn: earth resistance, magnetic and electromagnetic methods (including ground penetrating radar), together with an appreciation of more esoteric approaches, such as the use of micro-gravity survey to detect buried chambers and voids. The physical principles and field instrumentation involved for the acquisition of data with each method are considered and fully illustrated with case histories of results from the English Heritage archives.

    The development of paleomicrobiology with new molecular techniques such as metagenomics is revolutionizing our knowledge of microbial evolution in human history. The study of microbial agents that are concomitantly active in the same biological environment makes it possible to obtain a picture of the complex interrelations among the different pathogens and gives us the perspective to understand the microecosystem of ancient times. This research acts as a bridge between disciplines such as archaeology, biology, and medicine, and the development of paleomicrobiology forces archaeology to broaden and update its methods. This chapter addresses the archaeological issues related to the identification of cemeteries from epidemic catastrophes (typology of burials, stratigraphy, topography, paleodemography) and the issues related to the sampling of human remains for biomolecular analysis. Developments in the field of paleomicrobiology are described with the example of the plague. Because of its powerful interdisciplinary features, the paleomicrobiological study of Yersinia pestis is an extremely interesting field, in which paleomicrobiology, historical research, and archeology are closely related, and it has important implications for the current dynamics of epidemiology.

    The development of Synthetic Aperture Radar (SAR) in terms of multi-band, multi-polarization and high-resolution data, favored the application of this technology also in archaeology [1]. Different approaches based on both single and multitemporal data analysis, exploiting the backscattering and the penetration of radar data, have been used for a number of archaeological sites and landscapes [2-5]. Nevertheless, the capability of this technology in archaeological applications has so far not been fully assessed. It lacks a contribution aimed at evaluating the potential of SAR technology for the same study area by using different bands, spatial resolutions and data processing solutions. In the framework of the Chinese-Italian bilateral project "Smart management of cultural heritage sites in Italy and China: Earth Observation and pilot projects", we addressed some pioneering investigations to assess multi-mode (multi-band, temporal, resolution) satellite SAR data (including X-band TerraSAR, C-band Envisat and L-band ALOS PALSAR) in archaeological prospection of the Silk road [6]. The Silk Road, a series of trade and cultural transmission routes connecting China to Europe, is the witness of civilization and friendship between the East and West dated back to 2000 years ago, that left us various relics (e.g. lost cities) to be uncovered and investigated.. In particular, the assessment has been performed in the Xinjiang and Gansu section pf the Silk Road focusing on : i) the subsurface penetration capability of SAR data in the arid and semi-arid region ii) and sensitivity of SAR imaging geometry for the detection of relics As regards the point i) , apart from the soil moisture, the penetration is seriously restricted by the soil porosity. For instance, negligible penetration signs were detected in Yumen Frontier Pass either using X- or L-band SAR data due to the occurrence of Yardang landscape. As regards the point ii), the flight path of SAR images in parallel with the

    2010-01-01

    Southern African populations speaking languages that are often - but inaccurately - grouped together under the label 'Khoisan' are an important focus of molecular genetic research, not least in tracking the early stages of human genetic diversification. This paper reviews these studies from an archaeological standpoint, concentrating on modern human origins, the introduction of pastoralism to southern Africa and admixture between the region's indigenous foragers and incoming Bantu-speaking farmers. To minimise confusion and facilitate correlation with anthropological, linguistic and archaeological data it emphasises the need to use ethnolinguistic labels accurately and with due regard for the particular histories of individual groups. It also stresses the geographically and culturally biased nature of the genetic studies undertaken to date, which employ data from only a few 'Khoisan' groups. Specific topics for which the combined deployment of genetic and archaeological methods would be particularly useful include the early history of Ju-Hoan- and Tuu-speaking hunter-gatherers, the expansion of Khoe-speaking populations, the chronology of genetic exchange between hunter-gatherers and farmers, and the origins of the Sotho/Tswana- and Nguni-speaking populations that dominate much of southern Africa today.

    In Italy, in recent years there has been a perspective-shift in archaeological education and communication, showing how current educational activities for the many publics of archaeology have incorporated practices and approaches that belong to different disciplinary ambits, although partially overlapping: the heritage education field with its theoretical-pedagogical reflection (especially at European level as well as educational practices on the one hand; and the new ‘global’ approach to heritage, which is expressed by the public archaeology sector of Anglo-Saxon matrix. Actually a real ‘educational archaeology’ is emerging, i.e. an archaeological activity, not delegated to other mediators, but personally conducted by archaeologists with educational, social and cultural objectives and aims: first, to transmit knowledge and skills enabling visitors to understand the archaeological evidence and the meaning itself of the dig, of the archaeological sites and heritage; second, to implement innovative and diversified educational and communication strategies, able to reach wider audiences and, consequently, to meet the new demands of social inclusion and cultural participation; third, but not least, to reassert the meaning of archaeological heritage as well as of the discipline and its actors, as a shared value and a potential of growth for citizens, communities and society as a whole.

    This report describes a preliminary sample inventory and offers an initial evaluation of settlement and land-use patterns for the Geothermal Resources Subzones (GRS) area, located in Puna District on the island of Hawaii. The report is the second of a two part project dealing with archaeology of the Puna GRS area -- or more generally, the Kilauea East Rift Zone. In the first phase of the project, a long-term land-use model and inventory research design was developed for the GRS area and Puna District generally. That report is available under separate cover as Archaeology in the Kilauea East Rift Zone, Part I: Land-Use Model and Research Design. The present report gives results of a limited cultural resource survey built on research design recommendations. It offers a preliminary evaluation of modeled land-use expectations and offers recommendations for continuing research into Puna`s rich cultural heritage. The present survey was conducted under the auspices of the United States Department of Energy, and subcontracted to International Archaeological Research Institute, Inc. (IARII) by Martin Marietta Energy Systems, Inc. The purpose of the archaeological work is to contribute toward the preparation of an environmental impact statement by identifying cultural materials which could be impacted through completion of the proposed Hawaii Geothermal Project.

    Full Text Available Clearly it is not always feasible to conserve and exhibit the archaeological remains in situ, either for lack of funds in some cases, or for manifest incompatibility with the new land uses in others. This second case mix, ie the need to "free" land for new uses, sentences, in most cases, the archaeological remains to suffer a partial destruction since only movable materials are extracted, preserved and in some cases presented to the public, while the unmovable archaeological heritage, ie fixed archaeological structures, is destroyed, once it has been "properly" documented. However, in this field there is a kind of third way in which archaeological remains, including structures, are preserved and on display, while clearing the ground originally occupied. It is the displacement of archaeological structures. This article discusses the long history of such interventions in the Spanish case, making a typological classification proposal and finally a critical appraisal.

  7. ARCHAEOLOGICAL SITE MONITORING: UAV PHOTOGRAMMETRY CAN BE AN ANSWER

    Directory of Open Access Journals (Sweden)

    F. Rinaudo

    2012-07-01

    Full Text Available During archaeological excavations it is important to monitor the new excavated areas and findings day by day in order to be able to plan future excavation activities. At present, this daily activity is usually performed by using total stations, which survey the changes of the archaeological site: the surveyors are asked to produce day by day draft plans and sections which allow archaeologists to plan their future activities. The survey is realized during the excavations or just at the end of every working day and drawings have to be produced as soon as possible in order to allow the comprehension of the work done and to plan the activities for the following day. By using this technique, all the measurements, even those not necessary for the day after, have to be acquired in order to avoid a ‘loss of memory’. A possible alternative to this traditional approach is aerial photogrammetry, if the images can be acquired quickly and at a taken distance able to guarantee the necessary accuracy of a few centimeters. Today the use of UAVs (Unmanned Aerial Vehicles can be considered a proven technology able to acquire images at distances ranging from 4 m up to 20 m: and therefore as a possible monitoring system to provide the necessary information to the archaeologists day by day. The control network, usually present at each archaeological site, can give the stable control points useful for orienting a photogrammetric block acquired by using an UAV equipped with a calibrated digital camera and a navigation control system able to drive the aircraft following a pre-planned flight scheme. Modern digital photogrammetric software can solve for the block orientation and generate a DSM automatically, allowing rapid orthophoto generation and the possibility of producing sections and plans. The present paper describes a low cost UAV system realized by the research group of the Politecnico di Torino and tested on a Roman villa archaeological site located in

    Full Text Available The graphical documentation process of archaeological pieces requires the active involvement of a professional artist to recreate beautiful illustrations using a wide variety of expressive techniques. Frequently, the artist’s work is limited by the inconvenience of working only with the photographs of the pieces he is going to illustrate. This paper presents a software tool that allows the easy generation of illustrations in real time from 3D scanned models. The developed interface allows the user to simulate very elaborate artistic styles through the creation of diagrams by using the available virtual lights. The software processes the diagrams to render an illustration from any given angle or position. Among the available virtual lights, there are well known techniques as silhouettes enhancement, hatching or toon shading.

    To assess the effectiveness of the self-regulatory Canadian Children's Food and Beverage Advertising Initiative (CAI) in limiting advertising of unhealthy foods and beverages on children's preferred websites in Canada.Design/Setting/SubjectsSyndicated Internet advertising exposure data were used to identify the ten most popular websites for children (aged 2-11 years) and determine the frequency of food/beverage banner and pop-up ads on these websites from June 2015 to May 2016. Nutrition information for advertised products was collected and their nutrient content per 100 g was calculated. Nutritional quality of all food/beverage ads was assessed using the Pan American Health Organization (PAHO) and UK Nutrient Profile Models (NPM). Nutritional quality of CAI and non-CAI company ads was compared using χ 2 analyses and independent t tests. About 54 million food/beverage ads were viewed on children's preferred websites from June 2015 to May 2016. Most (93·4 %) product ads were categorized as excessive in fat, Na or free sugars as per the PAHO NPM and 73·8 % were deemed less healthy according to the UK NPM. CAI-company ads were 2·2 times more likely (OR; 99 % CI) to be excessive in at least one nutrient (2·2; 2·1, 2·2, Pfood and beverage advertising on children's preferred websites in Canada.

    Full Text Available The two editors argue in their preface to the volume that the particular sociopolitical context of Latin America has led to a regionalism not seen in North America or Europe, resulting in a unique variety of archaeology. They particularly conceive "Latin American archaeology" in this case to he only that archaeology done by individuals who are citizens of the countries of the region, and they ex­clude from consideration as being considered "Latin American archaeology" the work of foreign scholars such as North Americans and Europeans who do research in the region.

    2011-08-01

    Talensi materia medica is varied, encompassing plant, mineral, and animal substances. Healing, medicines, and medicinal practices and knowledge can be shrine-based and linked with ritual practices. This is explored utilising ethnographic data and from an archaeological perspective with reference to future possibilities for research both on Talensi medicine and, by implication, more generally through considering the archaeology of Talensi medicine preparation, use, storage, spread, and disposal. It is suggested that configuring the archaeology of medicine shrines and practices more broadly in terms of health would increase archaeological visibility and research potential.

    Gonzalez M, P R

    1999-07-01

    In this thesis an specific method for dating local archaeological and geological samples based on the phenomenon of thermoluminescence (TL) using the fine grain and quartz inclusion techniques is developed. Taking into account that this work is interesting for professionals working in the fields of Physics, Chemistry, Archaeology, Anthropology and related sciences, some basic concepts are described to have a better comprehension. Chapter 1 describes the concept of radioactivity, remarking the importance of the different decay types as well as the main radioactive series and the energy liberated in the process.

    In this thesis an specific method for dating local archaeological and geological samples based on the phenomenon of thermoluminescence (TL) using the fine grain and quartz inclusion techniques is developed. Taking into account that this work is interesting for professionals working in the fields of Physics, Chemistry, Archaeology, Anthropology and related sciences, some basic concepts are described to have a better comprehension. Chapter 1 describes the concept of radioactivity, remarking the importance of the different decay types as well as the main radioactive series and the energy liberated in the process. The causes of radioactive desequilibrium are also considered in the case for radon. Another important aspect taken into account in this chapter is the radioisotope production and its relationship with the neutron activation analysis used for the determination of the Uranium and Thorium concentrations in the samples. The TL phenomenon is described in Chapter 2, emphasizing the importance of the process of thermally stimulated luminescence best known as TL and its application for dating minerals of different origin. Chapter 3 shows some important antecedents remarking some aspects of the techniques commonly used for dating purposes. Chapter 4 shows the different methods used for the sample preparation.

  15. Is the Truth Down There?: Cultural Heritage Conflict and the Politics of Archaeological Authority

    Directory of Open Access Journals (Sweden)

    Full Text Available The selective pressures and processes of cultural heritage management effectively disinherit some interest groups. Where this occurs in the context of postcolonial or nationalist conflict, the material archaeological record may be referenced to support or reject particular views. The disciplinary assumptions behind the archaeological evidence so produced are not usually contested in judicial contexts. A review of archaeology’s theoretical foundations suggests that this naivety itself may be problematic. A descriptive culture history approach dominated archaeology over the first half of the twentieth century with a strong political appeal to nationalist politics. Subsequently archaeology became concerned with processual explanation and the scientific identification of universal laws of culture, consistent with postwar technological optimism and conformity. A postprocessual archaeology movement from the 1970s has promoted relativism and challenged the singular authority of scientific explanation. Archaeologists caught within this debate disagree over the use of the archaeological record in situations of political conflict. Furthermore, the use of archaeology in the sectarian debate over the Ayodhya birthplace of Rama suggests that the material record of the past can become highly politicized and seemingly irresolvable. Archaeological research is also subject to other blatant and subtle political pressures throughout the world, affecting the nature and interpretation of the record. A system that privileges archaeological information values may be irrelevant also to communities who value and manage their ancestral heritage for customary purposes. Collectively this review of theory and applied knowledge suggests that it is unrealistic to expect that archaeology can authoritatively resolve strident claims and debates about the past. Instead, an important contemporary contribution of archaeology may be its potential to document cultural and

  16. Centrobin-mediated Regulation of the Centrosomal Protein 4.1-associated Protein (CPAP) Level Limits Centriole Length during Elongation Stage*

    Microtubule-based centrioles in the centrosome mediate accurate bipolar cell division, spindle orientation, and primary cilia formation. Cellular checkpoints ensure that the centrioles duplicate only once in every cell cycle and achieve precise dimensions, dysregulation of which results in genetic instability and neuro- and ciliopathies. The normal cellular level of centrosomal protein 4.1-associated protein (CPAP), achieved by its degradation at mitosis, is considered as one of the major mechanisms that limits centriole growth at a predetermined length. Here we show that CPAP levels and centriole elongation are regulated by centrobin. Exogenous expression of centrobin causes abnormal elongation of centrioles due to massive accumulation of CPAP in the cell. Conversely, CPAP was undetectable in centrobin-depleted cells, suggesting that it undergoes degradation in the absence of centrobin. Only the reintroduction of full-length centrobin, but not its mutant form that lacks the CPAP binding site, could restore cellular CPAP levels in centrobin-depleted cells, indicating that persistence of CPAP requires its interaction with centrobin. Interestingly, inhibition of the proteasome in centrobin-depleted cells restored the cellular and centriolar CPAP expression, suggesting its ubiquitination and proteasome-mediated degradation when centrobin is absent. Intriguingly, however, centrobin-overexpressing cells also showed proteasome-independent accumulation of ubiquitinated CPAP and abnormal, ubiquitin-positive, elongated centrioles. Overall, our results show that centrobin interacts with ubiquitinated CPAP and prevents its degradation for normal centriole elongation function. Therefore, it appears that loss of centrobin expression destabilizes CPAP and triggers its degradation to restrict the centriole length during biogenesis. PMID:25616662

  17. A Whiter Shade of Grey: A new approach to archaeological grey literature using the XML version of the TEI Guidelines

    Directory of Open Access Journals (Sweden)

    Gail Falkingham

    2005-04-01

    Full Text Available This article has arisen through the author's interest in two contemporary issues within archaeology: the production and dissemination of grey literature and the potential of XML. Grey literature is examined, with specific reference to unpublished reports literature produced in the present climate of developer-funded archaeology in England. There are concerns about the accessibility of this literature, both from within and beyond the archaeological profession. The vast majority of reports are word-processed and then printed in hard-copy format for limited distribution. The original, digital document however, has largely been seen as a by-product. Awareness of the importance of these digital reports, and their preservation must be raised. Electronic means of delivery and dissemination via the World Wide Web offer huge potential and present opportunities for new ways of working. Archaeology is not alone in seeking to promote the accessibility of grey literature; indeed there are many disciplines that have created online initiatives aiming to do just this, utilising a variety of means and a range of electronic file formats. The use of XML technology appears to offer many advantages over traditional formats, such as word-processed, PDF and even (XHTML files, particularly with regard to the manipulation and presentation of encoded electronic text. Increasingly, XML technology is being used for electronic delivery and dissemination and the pros and cons of so doing are discussed in this article. This theme has been developed by the author through a 'proof of concept' practical case study of three unpublished grey literature archaeology reports from the North Yorkshire Historic Environment Record. XML documents have been created from the original word-processed electronic reports by the manual application of XML markup, the methodology for which was devised following the XML version of the Text Encoding Initiative's TEI P4 Guidelines.

    In archaeology, data obtained from the analysis of material evidence (i.e., the archaeological record) from extensive excavations have been a significant means for the ultimate development of interpretations about human life in the past. Therefore, the methodological procedures and tools employed during fieldwork are of crucial importance due to their effect on the information likely to be recovered. In the case of maritime archaeology, the development of rigorous methods and techniques allowed for reaching outcomes as solid as those from the work performed on land. These improvements constituted one of the principal supports—if not, the most important pillar—for its acceptance as a scientific field of study. Over time, the growing diversity of sites under study (e.g., shipwrecks, ports, dockyards, and prehistoric settlements) and the underwater environments encountered made it clear that there was a need for the application of specific methodological criteria, in accordance with the particularities of the sites and of each study (e.g., the research aims and the available resources). This article presents some ideas concerning the methodologies used in South American investigations that have exhibited a strong emphasis on the analysis of historical shipwrecks (the sixteenth to twentieth centuries). Based on a state-of-the-knowledge review of these research projects, in particular where excavations were conducted, the article focuses on the details of the main strategies adopted and results achieved. The ideas proposed in this article can be useful as a starting point for future activities of surveying, recording, and excavating shipwrecks.

    Long term climate records are rare, consisting of unique and unrepeatable measurements. However, data do exist in analogue form in archives, libraries and other repositories around the world. The Global Sea Level Observing System (GLOSS) Group of Experts aims to provide advice on locating hidden tide gauge data, scanning and digitising records and quality controlling the resulting data. Long sea level data time series are used in Intergovernmental Panel on Climate Change (IPCC) assessment reports and climate studies, in oceanography to study changes in ocean currents, tides and storm surges, in geodesy to establish national datum and in geography and geology to monitor coastal land movement. GLOSS has carried out a number of data archaeology activities over the past decade, which have mainly involved sending member organisations questionnaires on their repositories. The Group of Experts is now looking at future developments in sea level data archaeology and how new technologies coming on line could be used by member organisations to make data digitisation and transcription more efficient. Analogue tide data comes in two forms charts, which record the continuous measurements made by an instrument, usually via a pen trace on paper ledgers containing written values of observations The GLOSS data archaeology web pages will provide a list of software that member organisations have reported to be suitable for the automatic digitisation of tide gauge charts. Transcribing of ledgers has so far proved more labour intensive and is usually conducted by people entering numbers by hand. GLOSS is exploring using Citizen Science techniques, such as those employed by the Old Weather project, to improve the efficiency of transcribing ledgers. The Group of Experts is also looking at recent advances in Handwritten Text Recognition (HTR) technology, which mainly relies on patterns in the written word, but could be adapted to work with the patterns inherent in sea level data.

  20. A Virtual Tomb for Kelvingrove: Virtual Reality, Archaeology and Education

    Directory of Open Access Journals (Sweden)

    1999-11-01

    Full Text Available The use of computers as an educational resource in museums is becoming increasingly popular as more and more institutions realise that multimedia displays are very successful in imparting a broad variety of information. Although three-dimensional reconstructions of sites and structures have been used in archaeology for many years, the majority of museum computer installations have dealt with two-dimensional media because of the costs, equipment and labour involved in producing interactive 3D scenes. The birth of VRML (Virtual Reality Modeling Language has changed the way virtual reality is implemented and viewed. As an internet protocol, VRML can be used on most major platforms and implemented by anyone with a word-processing package, an internet browser, and the relevant plug-in. There is no reason why this new technology cannot be adopted by archaeologists and museums to produce virtual reality models of structures, sites and objects to aid the research of specialists and the education of the public. This project (undertaken at the Humanities Advanced Technology and Information Institute, University of Glasgow, Scotland, between May and October 1998 investigated the practicalities involved in using VRML to create a virtual reality model for use in a public space. A model of the Egyptian tomb of Sen-nedjem was developed for installation in the Egyptian Gallery of the Kelvingrove Museum and Art Gallery, Glasgow, in the hope that the introduction of this computer display would encourage the museum visitor's interest in the gallery's existing artefacts. Creation of the model would also investigate the possibility of using VRML to build accurate archaeological reconstructions cheaply and efficiently using publicly available software and existing archaeological resources. A fully functioning virtual reality model of the tomb of Sen-nedjem has been created, incorporating interactive elements, photorealistic representation, and animation, and this

    Ground-penetrating radar (GPR) techniques are increasingly being used to aid reconnaissance and pre-excavation surveys at many archaeological sites. As a 'remote sensing' tool, GPR provides a high resolution graphic profile of the subsurface. Radar profiles are used to detect, identify, and locate buried artifacts. Ground-penetrating radar provides a rapid, cost effective, and nondestructive method for identification and location analyses. The GPR can be used to facilitate excavation strategies, provide greater areal coverage per unit time and cost, minimize the number of unsuccessful exploratory excavations, and reduce unnecessary or unproductive expenditures of time and effort.

    In the course of mitigation of earthworks associated with residential development at Omaha, 249 middens were recorded and investigated. Dates range from about AD 1400-1700, placing the occupation and use of Omaha firmly within the late phase of prehistory. The middens contained very little other than shell, and we interpret their use as a combination of industrial scale shellfish processing and formal gatherings. The economic analysis of Omaha is fairly straight forward, but we also offer a socially oriented explanation to account for aspects of the archaeology that clearly are not economic.

    Prompt γ-ray analysis using the internal monostandard method was applied to voluminous archaeological bronze mirrors produced in ancient China. Sn/Cu content ratios were determined nondestructively by this method. Furthermore, Au/Cu, As/Cu, and Sb/Cu content ratios were determined by means of measuring decay γ-rays emitted from radioactive nuclides produced within samples via (n,γ) reactions. It is clear that the Sn/Cu content ratios in bronze mirrors produced in the Sung era is smaller than in ones produced in between the Han and the Tung era. (author)

    This study aims to evaluate the use of Laser Fluorescent as a non-destructive technique for identification of natural dyes on archaeological textile objects. In this study wool textile samples were dyed with 10 natural dyes such as cochineal, cutch, henna, indigo, Lac, madder, safflower, saffron, sumac and turmeric. These dyes common present on archaeological textile objects to be used as standard dyed textile samples. These selected natural dyes will be used as known references that can be used a guide to identify unknown archaeological dyes. The dyed textile samples were investigated with laser radiation in different wavelengths to detect the best wavelengths for identification each dye. This study confirms that Laser Florescent is very useful and a rapid technique can be used as a non-destructive technique for identification of natural dyes on archaeological textile objects. The results obtained with this study can be a guide for all conservators in identification of natural organic dyes on archaeological textile objects.

    Full Text Available The authors introduce for discussion materials of archaeological studies conducted by the team of the Volga Archaeological Expedition of the Mari State University in Ulyanovsk Oblast of the Russian Federation in 2010. Two of the studied archaeological sites seem to be most interesting: they are situated near Bolshie Klyuchishi village (Ulyanovsk District, Ulyanovsk Oblast. Archaeological materials collected during the excavations of these settlements have a very broad time span, which allows suggesting that Bolshie Klyuchishi is a multilayered archaeological complex. Both settlements yielded the Srubnaya culture handmade ceramics of 16th – 13th centuries BC. Moreover, Bolshie Klyuchishi-7 contained items of iron and slag, and Bolshie Klyuchishi-8 yielded sherds of 13th – 14th centuries wheel- made Bulgarian ceramics.

    Of all the kind of artifacts which may be found at archaeological sites, ceramics are surely among the most important. A ceramic material is highly durable, and virtually unchanged after hundred of years from its date of manufacture. Because of this, a ceramic will always be an important object for serious studies to determine which culture produced it, to date cultures, reconstruct economic patterns and social organization, and establish routes of trade or simply to classify the different types of ceramics. The aim of this paper was to perform a thermoluminescent analysis of archaeological ceramic samples belonging to Teotenango, Mexico. The analysis is complemented with a physicochemical characterization by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-Ray Diffraction (XRD). TL analysis shows some differences when the samples are exposed to ionizing radiation field, while SEM analysis shows a porous and granular structure in all samples, EDS analysis shows oxygen (O), aluminum (Al), silicon (Si), iron (Fe), sodium (Na), phosphorus (P), potassium (K) and calcium (Ca) in significant amounts. These results allow establishing differences among ceramic samples belonging to the same place. (Author)

    With respect to the unknown aetiology of molar incisor hypomineralisation (MIH), it is unclear whether this phenomenon was overlooked in the last century as a result of a high number of caries in children or if this developmental disorder was not present until then. Therefore, this study determined the presence of MIH in historical dentitions and teeth. Dental remains from late medieval (n = 191, twelfth-sixteenth century, Regensburg, Germany), post-medieval (n = 33, sixteenth-eighteenth century, Passau, Germany) and modern age archaeological skeletal series (n = 99, nineteenth-twentieth century, Altdorf, Germany) were examined for MIH. In addition, linear enamel hypoplasia (LEH), diffuse opacities, hypoplasia and Turner's teeth were documented. MIH-related demarcated opacities or enamel breakdowns were found in only 15 (0.4 %) of the 3891 examined permanent teeth. Ten cases (3.1 %) from a total of 323 dentitions were classified as having MIH. In contrast, 98 individuals (30.3 %) showed LEH. Other enamel disorders were recorded in 64 individuals (19.8 %). With respect to the low number of affected dentitions and teeth, MIH most likely did not exist or was at least rarely present in the investigated archaeological case series. This study supports the hypothesis that MIH may be linked to contemporary living conditions or other health-related factors.

    The Great East Japan Earthquake on March 11, 2011 is said to be a once-in-1000-year catastrophic quake. The Tsunami triggered by the earthquake destroyed broad coastal areas in northeast Japan. As recovery from the earthquake proceeds, the demand for new road construction, housing hill development, and residential construction is rapidly increasing. Culture plays a critical role in the district's recovery. For that reason, before development, cultural properties in the corresponding districts must be urgently investigated. This is a must, although balancing cultural recovery with rapid economic recovery is no easy task. With this in mind, we have developed a new system focusing on speedy archaeological investigation and adequate documentation. The authors reexamined the existing investigation process to categorize tasks into two types: those that must be done only at archaeological sites (site A) and ones available at other places (site B). We then formulated a scheme where the tasks on both sites are performed simultaneously in parallel over the network. Experiments are ongoing. This presentation reports the process and issues of our research and development.

  14. Archaeological excavation of T10/993 at Matarangi

    This report describes the excavation of a small midden site, T10/993, representative of a number of like sites in the sand dunes at Matarangi on the east coast of the Coromandel Peninsula. Few sites of this type have been investigated archaeologically yet they are the remains of a very important part of the Maori economic cycle. The sites could be termed shellfish processing sites. The excavation was a condition imposed by Historic Places Trust on the granting of an authority to modify sites T10/993 and 994 (HPT Authority no. 1997/42), prior to destruction of the sites (Furey 1998). Matarangi Beach Estates commissioned the author to undertake an archaeological site survey of a grassed area at Matarangi Beach which was to be Stage 14 of the urban housing development. The area was in excess of 13 hectares. Two sites were found, T10/993 and 994, and recommendations made for monitoring of the dunes as the topsoil was removed (Furey 1997a).

    During the last 20 years, new evidence of pre-Clovis cultures in America has appeared. After we show why putative archaeological finds are so polemic in Pleistocene context ancient claims mainly Brazilian ones, are revisited (Toca da Esperanca, Itaborai, Pedra Furada, Lapa Vermelha, Alice Boer). No archaeological find dated more than 12 or 13,000 BP has been able to convince all scholars. Some have stratigraphic disturbances, others dubious dating, or putative structures and airfacts could have been made by natural processes. By 12,000 BP, instruments and structures point obviously to an effective presence of Man in both Americas. For some archaeologists, there is evidence of at least two main technological traditions in America during the Clovis period, that point to the entrance of several groups into the continent. Otherwise, independent cultural evolution in North vs. South America, by 11,500 BP would suggest a long previous adaptation of Man during the pleistocene period. (author) 33 refs., 4 figs.

  16. A survey of archaeological and geological samples dated in 1990

    A survey of dated archaeological and geological samples is given, using thermoluminescence dating. Some of the sediment samples were also dated by means of optically stimulated luminescence (OSL) using a newly developed infrared diode system. In most cases the luminescence dates are in accordance with archaeological and geological estimates. Some discrepancies were found because some feldspar samples exhibited severe anomalous fading. It may be possible to avoid this problem by basing the dating on OSL of quartz. For sediment samples of Eemian or Early Weichselian age severe underestimates were encountered with both methods. The reason might be related to the large difference between the natural dose rate and that used in laboratory irradiations. Traps corresponding to low-temperature peaks such as the 150 deg. C peak in feldspars will remain almost empty under natural conditions, but will fill up to saturation under laboratory irradiation and thereby more charges will be captured in high-temperature traps. As a result, natural growth curves and laboratory produced luminescence growth curves will have different slopes and this will lead to underestimation. This problem might avoided by holding samples at an elevated temperature during laboratory irradiation, thus keeping the low-temperature traps empty. Preliminary experiments where feldspar samples were held at 130 deg. C during irradiation have given promising results. (AB) (31 refs.)

    Archaeometry is a consolidated field with a wide application of nuclear analytical techniques for the characterization, protection, and restoration of archaeological pieces. This project aimed at studying the elementary chemical composition of 70 ceramic fragments samples from Sao Paulo II archaeological site, located along the Solimoes River channel, next to Coari city, in Brazilian Amazon. The characterization of samples was performed by neutron activation analysis (NAA). By the determination of 24 elements in the ceramic fragments ( Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Sb, Sm. Rb, Se, Ta, Tb, Th, U, Yb and Zn), it was possible to define groups of samples regarding the similarity/dissimilarity in elementary chemical composition. For such a task, the multivariate statistical methods employed were cluster analysis (C A), principal component analysis (PCA) and discriminant analysis (DA). Afterwards, seven ceramic fragments were selected based on the groups previously established, for the characterization of the site temporal horizon. Those ceramic fragments were analyzed by thermoluminescence (TL) and EPR for dating purposes. The firing temperatures were determined by electron paramagnetic resonance (EPR) technique, in order to infer about some aspects of the ceramic manufacture employed by the ancient peoples that lived in Sao Paulo 11. By the results obtained in this study, it was possible to identify the quantity of clay sources employed by the ceramists and the age of the ceramic pieces. Therefore, the results of this research may contribute to the study on the occupation dynamics in the pre-colonial Brazilian Amazon. (author)

  18. Archaeological Excavation and Deep Mapping in Historic Rural Communities

    2015-09-01

    Full Text Available This paper reviews the results of more than a hundred small archaeological “test pit” excavations carried out in 2013 within four rural communities in eastern England. Each excavation used standardized protocols in a different location within the host village, with the finds dated and mapped to create a series of maps spanning more than 3500 years, in order to advance understanding of the spatial development of settlements and landscapes over time. The excavations were all carried out by local volunteers working physically within their own communities, supported and advised by professional archaeologists, with most test pits sited in volunteers’ own gardens or those of their friends, family or neighbors. Site-by-site, the results provided glimpses of the use made by humans of each of the excavated sites spanning prehistory to the present day; while in aggregate the mapped data show how settlement and land-use developed and changed over time. Feedback from participants also demonstrates the diverse positive impacts the project had on individuals and communities. The results are presented and reviewed here in order to highlight the contribution archaeological test pit excavation can make to deep mapping, and the contribution that deep mapping can make to rural communities.

    Full Text Available Roman gold jewellery, which was excavated in Ptuj (Poetovio and consists of a necklace, earrings and a braceletwith embedded emeralds, is part of the Slovenian archaeological artefacts collections. Crystallographic characteristics,inclusions, luminous phenomena and geological characteristics were determined in order to establish theorigin of the emeralds. Chemical composition of the emeralds was determined non-destructively using the methodsof proton-induced X-rays and gamma rays (PIXE/PIGE. The results were compared with reference emeraldsfrom Habachtal in Austria and with green beryls from the Ural Mts. Literature data for emeralds from Egypt andmodern-day Afghanistan area were used to interpret the results. Specifically, these sites were known for emeraldsbeing mined for jewellery in Roman times. It was assumed that emeralds from archaeological artefacts originatedfrom Habachtal in Austria, given that this site was the nearest to the place where found. But the emeralds fromthe necklace and earrings in fact came from Egyptian deposits. The origin of emeralds from the bracelet could nothave been determined absolutely reliably due to the lack of comparative materials; they may originate from a site inmodern-day Afghanistan or from Egypt, but certainly not from the same site as the previously mentioned emeraldsin the necklace and earrings.

    Full Text Available V.F. Gening’s contribution to the study of the Volga Bulgaria and his views concerning the history and archaeology of this state formation are considered in the article. His sphere of interest first of all included the links between the Volga Bulgaria population and the tribes belonging to preceding cultures, such as Pyanoborye and Imenkovo ones. V.F. Gening investigated the Bolshie Tarkhany, Turaevo and Rozdestveno burial grounds dated by the 8-9th, 5th and 6-7th centuries A.D., and the materials collected modified the notion of the time and character of the Bulgars arrival in the Volga area. He reconsidered the chronology and interpretation of the archaeological monuments, which referred to the epoch preceding the Bulgars appearance on the Volga, and proposed a hypothesis of the Volga Bulgars as a Turkic-Ugrian ethnos. V.F. Gening created a periodization of the Bolgars history in Eastern Europe within the time span between 1st-3rd centuries AD and the early 13th century AD

    Compositions of ancient artefacts are examined for a variety of reasons including chronology, provenience, ancient technology and conservation studies. In particular, the elemental composition of archaeological pottery is of prime importance in fixing the origin of the pottery and thereby throwing light on trade routes and inter-regional connections between settlements in antiquity4. An intensive program of INAA was conducted at the Institute of Archaeology, The Hebrew University of Jerusalem, during the 1970-1990s5. Although that laboratory was closed as were other similar laboratories, new INAA laboratories have sprung up. Despite advances in other methods of analysis, INAA remains the favourite and best method for pottery provenience studies. The bulk of pottery data accumulated over the past five decades is based on INAA. These data, perhaps better than data obtained by other methods, can be integrated providing care is taken in accounting for the different standards employed by different laboratories and the different degrees of precisions attained. As a consequence projects that were suspended with the closure of laboratories can sometimes be concluded by combining resources from different laboratories. Examples will be given on how data from four laboratories, Hebrew University, Lawrence Berkeley National Laboratory, Missouri University Research Reactor6 and the University of Texas at Austin are utilized

    Radiocarbon is a cosmogenic radioisotope equally distributed throughout the troposphere and biosphere. This fact enables its most common application-radiocarbon dating. Natural equilibrium of radiocarbon has been disturbed by diverse anthropogenic activities during the last {approx}150 years, enabling also the use of {sup 14}C in various environmental applications. Here we present three types of studies by using {sup 14}C that were performed in the Zagreb Radiocarbon Laboratory. {sup 14}C in atmospheric CO{sub 2} has been monitored at several sites with various anthropogenic influences and the difference between the clean-air sites, the industrial city and the vicinity of a nuclear power plant has been established. {sup 14}C has been applied in geochronology of karst areas, especially in dating of tufa, speleothems and lake sediments, as well as in studies of geochemical carbon cycle. {sup 14}C has been used in various archaeological studies, among which the dating of the early Neolithic settlements in Croatia is presented. In these studies {sup 14}C was measured by radiometric techniques, i.e., by gas proportional counting and more recently by liquid scintillation counting (LSC). Two sample preparation techniques for LSC measurement were used: benzene synthesis for archaeological dating and other applications that require better precision, and direct absorption of CO{sub 2} for monitoring purposes. The presented results show that various studies by using {sup 14}C can be successfully performed by the LSC technique, providing a large enough sample (>1 g of carbon).

  3. Digital Astronaut Photography: A Discovery Dataset for Archaeology

    Astronaut photography acquired from the International Space Station (ISS) using commercial off-the-shelf cameras offers a freely-accessible source for high to very high resolution (4-20 m/pixel) visible-wavelength digital data of Earth. Since ISS Expedition 1 in 2000, over 373,000 images of the Earth-Moon system (including land surface, ocean, atmospheric, and lunar images) have been added to the Gateway to Astronaut Photography of Earth online database (http://eol.jsc.nasa.gov ). Handheld astronaut photographs vary in look angle, time of acquisition, solar illumination, and spatial resolution. These attributes of digital astronaut photography result from a unique combination of ISS orbital dynamics, mission operations, camera systems, and the individual skills of the astronaut. The variable nature of astronaut photography makes the dataset uniquely useful for archaeological applications in comparison with more traditional nadir-viewing multispectral datasets acquired from unmanned orbital platforms. For example, surface features such as trenches, walls, ruins, urban patterns, and vegetation clearing and regrowth patterns may be accentuated by low sun angles and oblique viewing conditions (Fig. 1). High spatial resolution digital astronaut photographs can also be used with sophisticated land cover classification and spatial analysis approaches like Object Based Image Analysis, increasing the potential for use in archaeological characterization of landscapes and specific sites.

    Muon tomography is a potential non-invasive technique for internal structure scanning. It has already interesting applications in geophysics and can be used for archaeological purposes. Muon tomography is based on the measurement of the muon flux after crossing the structure studied. Differences on the mean density of these structures imply differences on the detected muon rate for a given direction. Based on this principle, Monte Carlo simulations represent a useful tool to provide a model of the expected muon rate and angular distribution depending on the composition of the studied object, being useful to estimate the expected detected muons and to better understand the experimental results. These simulations are mainly dependent on the geometry and composition of the studied object and on the modelling of the initial muon flux at surface. In this work, the potential of muon tomography in archaeology is presented and evaluated with Monte Carlo simulations by estimating the differences on the muon rate due to the presence of internal structures and its composition. The influence of the chosen muon model at surface in terms of energy and angular distributions in the final result has been also studied.

  5. Reconstructing the archaeological landscape of Southern Dobrogea: integrating imagery

    2007-10-01

    The recent integrated aerial photographic assessment of Southern Dobrogea, Romania) is part of the first author's British Academy funded research programme 'Contextualizing change on the Lower Danube: Roman impact on Daco-Getic landscapes'. This seeks to study the effect of the Roman conquest and occupation on the native Daco-Getic settlement pattern on the Lower Danube. The methodology involves integrating a range of remotely sensed imagery including: low altitude oblique aerial photographs, obtained through traditional aerial reconnaissance; medium altitude vertical photographs produced by German, British and American military reconnaissance during the Second World War, selected from The Aerial Reconnaissance Achive at Keele University; and high altitude de-classified military satellite imagery (Corona) from the 1960s, acquired from the USGS. The value of this approach lies not just in that it enables extensive detailed mapping of large archaeological landscapes in Romania for the first time, but also that it allows the recording of archaeological features permanently destroyed by more recent development across wide areas. This paper presents some results and addresses some of the problems raised by each method of data acquisition.

  6. Vulnerability assessment of archaeological sites to earthquake hazard: An indicator based method integrating spatial and temporal aspects

    2017-07-01

    Full Text Available Across the world, numerous sites of cultural heritage value are at risk from a variety of human-induced and natural hazards such as war and earthquakes. Here we present and test a novel indicator-based method for assessing the vulnerability of archaeological sites to earthquakes. Vulnerability is approached as a dynamic element assessed through a combination of spatial and temporal parameters. The spatial parameters examine the susceptibility of the sites to the secondary Earthquake Environmental Effects of ground liquefaction, landslides and tsunami and are expressed through the Spatial Susceptibility Index (SSi. Parameters of physical vulnerability, economic importance and visitors density examine the temporal vulnerability of the sites expressed through the Temporal Vulnerability Index (TVi. The equally weighted sum of the spatial and temporal indexes represents the total Archaeological Site Vulnerability Index (A.S.V.I.. The A.S.V.I method is applied at 16 archaeological sites across Greece, allowing an assessment of their vulnerability. This then allows the establishment of a regional and national priority list for considering future risk mitigation. Results indicate that i the majority of the sites have low to moderate vulnerability to earthquake hazard, ii Neratzia Fortress on Kos and Heraion on Samos are characterised as highly vulnerable and should be prioritised for further studies and mitigation measures, and iii the majority of the sites are susceptible to at least one Earthquake Environmental Effect and present relatively high physical vulnerability attributed to the existing limited conservation works. This approach highlights the necessity for an effective vulnerability assessment methodology within the existing framework of disaster risk management for cultural heritage.

  7. Advances in Neutron Activation Analysis of Large Objects with Emphasis on Archaeological Examples. Results of a Coordinated Research Project

    International Nuclear Information System (INIS)

    2018-03-01

    This publication is a compilation of the main results and findings of an IAEA coordinated research project (CRP). In particular, it discusses an innovative variation of neutron activation analysis (NAA) known as large sample NAA (LSNAA). There is no other way to measure the bulk mass fractions of the elements present in a large sample (up to kilograms in mass) non-destructively. Examples amenable to LSNAA include irregularly shaped archaeological artefacts, excavated rock samples, large samples of assorted ore, and finished products, such as nuclear reactor components. The CRP focused primarily on the application of LSNAA in the areas of archaeology and geology; however it was also open for further exploration in other areas such as industry and life sciences as well as in basic research. The CRP contributed to establish the validation of the methodology, and, in particular, it provided an opportunity for developing trained manpower. The specific objectives of this CRP were to: i) Validate and optimize the experimental procedures for LSNAA applications in archaeology and geology; ii) Identify the needs for development or upgrade of the neutron irradiation facility for irradiation of large samples; iii) Develop and standardize data acquisition and data analysis systems; iv) Harmonize and standardize data collection from facilities with similar kind of instrumentation for further analysis and benchmarking. Advantages of LSNAA applications, limitations and scientific and technological requirements are described in this publication, which serves as a reference of interest not only to the NAA experts, research reactor personnel, and those considering this technique, but also to various stakeholders and users such as researchers, industrialists, environmental and legal experts, and administrators.

    The determination of trace elements plays an important role in the characterization of archaeological ceramics. It is well established that ceramics can be grouped based on similarities/dissimilarities derived from chemical data. Different analytical methods can be applied to determine the sample composition. Instrumental neutron activation analysis (INAA) is the method preferred because present several advantages in relation to the other techniques. In this work, the elements determined were As, K, La, Lu, Na, Nd, Sb, Sm, U, Yb, Ba, Ce, Co, Cr, Cs, I, Fe, Hf, Rb, Sc, Ta , Tb, Th and Zn to carry out a preliminary chemical characterization in 44 ceramic samples from Sao Paulo II archaeological site by INAA. The site is located in Coari city, 363 km from Manaus, Amazonas state (AM). The elementary concentration results were studied using multivariate statistical methods. The similarity/dissimilarity among the samples was studied by means of discriminant analysis. The compositions group classification was done through cluster analysis, showing the formation of the three distinct groups of the ceramics. (author)

    Full Text Available In this paper we provide a description of airborne mapping LiDAR, also known as airborne laser scanning (ALS, technology and its workflow from mission planning to final data product generation, with a specific emphasis on archaeological research. ALS observations are highly customizable, and can be tailored to meet specific research needs. Thus it is important for an archaeologist to fully understand the options available during planning, collection and data product generation before commissioning an ALS survey, to ensure the intended research questions can be answered with the resultant data products. Also this knowledge is of great use for the researcher trying to understand the quality and limitations of existing datasets collected for other purposes. Throughout the paper we use examples from archeological ALS projects to illustrate the key concepts of importance for the archaeology researcher.

    European Middle-Pleistocene archaeological and/or paleontological sites lack a unified and precise chronological framework. Despite recent efforts mostly focused on methods such as OSL, ESR/U-series or cosmogenic nuclides, the age of numerous sites from this period fundamentally still relies on qualitative and speculative palaeoenvironmental and/or palaeontological/palaeoanthropological considerations. The lack of robust chronologies, along with the scarcity of human fossils, prevent coherent correlations between European sites which in turn limits our understanding of human diffusion dynamics, understand techno-cultural evolution or correlate archaeological sites with palaeoclimatic and environmental records. With the goal of providing an accurate and precise chronological framework based on a multi-method approach, a research network including geochronologists, archaeologist and paleoanthropologists from various French and Italian institutions launched in 2010 a wide study of Middle-Pleistocene archaeological sites of central and southern Italy. This study combining the 39Ar/40Ar method with palaeo-dosimetric methods applied to European sites in the age range of 700 ka to 300 ka is unprecedented. In parallel, a large effort has been done to improve the regional Middle-Pleistocene tephrostratigraphic database through a massive application of both high-precision 40Ar/39Ar geochronological and geochemical investigations. We illustrate our approach and results in addressing several key-sites such as Notarchirico, Valle Giumentina; Ceprano-Campogrande and La Polledrara di Cecanibbio. The accurate and precise chronological framework we built permits us to replace all the investigated archaeological and palaeontological records into a coherent climatic and environmental context. Furthermore, our work provides the opportunity to compare lithic industries from a technical and evolutionary point of view within a homogeneous temporal frame. These preliminary results border

    Full Text Available Currently, there are a variety of ways to make vector-based information available on the Web, but most are browser- and platform-dependent, proprietary, and unevenly supported (Laaker 2002, 13. Of the various solutions currently being explored by the greater Web community, one of the most promising is called Scalable Vector Graphics (SVG, which is part of the eXtensible Markup Language (XML. SVG was defined by a working group of the World Wide Web Consortium (W3C and has subsequently become their official recommendation for representing vector graphics on the Web in XML (Eisenberg 2002, 6; Watt 2002, xviii. Because SVG is an XML application, it is freely available, not dependent on a particular browser or platform, and interoperable with other XML applications. While there is no guarantee that SVG will be widely adopted for rendering vector-based information on the Web, development and recommendation by the W3C generally carries a great deal of weight, especially as browser developers move towards less proprietary support of W3C standards. In addition, use of XML continues to grow, so XML-based solutions like SVG should be explored by those interested in presenting vector graphics on the Web (Harold and Means 2002, 3. This discussion explores SVG as a potential tool for archaeologists. It includes some of the ways vector graphics are used in archaeology, and outlines the development and features of SVG, which are then demonstrated in the form of a case study. Large-scale plan and section drawings originally created on Permatrace were digitised by Guy Hopkinson for use in the Internet Archaeology publication Excavations at Cricklade, Wiltshire, 1975, by Jeremy Haslam, designed as an exercise in 'retrospective publication', to illustrate how traditional forms of visual recording might be digitised for online publication.

    Tropical spices have long been utilized in traditional medicine and cuisine. New archaeological evidence highlights temporal changes in the nature and scale of the ancient spice trade and in the ancient usage of these plants. Furthermore, a study of their 'materiality' highlights that the impact of spices extends beyond their material properties. Here the botanical remains of spices recovered from archaeological excavations at a port active in the Roman and medieval Islamic spice trade are evaluated. Recent excavations at Quseir al-Qadim, an ancient port located on the Red Sea coast of Egypt, have provided new evidence for the spice trade. Due to the arid conditions ancient botanical remains were preserved in abundance and these included spices, as well as a wide range of other food plants. Quseir al-Qadim was active as a transport hub during both the Roman and Islamic periods (ca. AD 1-250, known as Myos Hormos, and again during ca. AD 1050-1500, known as Kusayr), and the remains thus facilitate a study of temporal change in the trade and usage of these spices. Standard archaeobotanical methods were used to recover, identify and analyze these remains. At least seven tropical spices were recovered from the excavations, as well as several other tropical imports, including black pepper (Piper nigrum), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma sp.), fagara (cf. Tetradium ruticarpum), myrobalan (Terminalia bellirica and Terminalia chebula) and betelnut (Areca catechu). A marked contrast between the two chronological periods in the range of spices recovered points to changes in the nature and scale of the trade between the Roman and medieval Islamic periods, while differences in the contexts from which they were recovered help to identify temporal changes in the way in which the spices were utilized during those periods. Archaeological and textual evidence suggest that in antiquity spices were used in ritual (funeral rites

  13. What is Open Data in an Archaeological Context?

  14. Underwater inverse LIBS (iLIBS) for marine archaeology

    In recent years there have been enormous advances in nautical archaeology through developments in SONAR technologies as well as in manned and robotic submersible vehicles. The number of sunken vessel discoveries has escalated in many of the seas of the world in response to the widespread application of these and other new tools. Customarily, surviving artifacts within the debris field of a wreck are collected and then moved to laboratories, centers, or institutions for analyses and possible conservation. Frequently, the conservation phase involves chemical treatments to stabilize an artefact to standard temperature, pressure, and humidity instead of an undersea environment. Many of the artefacts encountered at an underwater site are now characterized and restored in-situ in accordance with modern trends in art conservation. Two examples of this trend are exemplified by the resting place of the wreck of the Titanic in the Atlantic and the Cancun Underwater Park in the Caribbean Sea. These two debris fields have been turned into museums for diving visitors. Several research groups have investigated the possibility of adapting the well-established analytical tool Laser Induced Breakdown Spectroscopy (LIBS) to in-situ elemental analyses of underwater cultural, historic, and archaeological artefacts where discovered, rather than as a phase of a salvage operation. As the underwater laser ablation associated with LIBS generates a "snowplough" shockwave within the aqueous matrix, the atomic emission spectrum is usually severely attenuated in escaping from the target. Consequently, probative experiments to date generally invoke a submerged air chamber or air jet to isolate water from the interaction zone as well as employ more complex double-pulse lasers. These measures impose severe logistical constraints on the examination of widely dispersed underwater artefacts. In order to overcome this constraint we report on water-immersion LIBS experiments performed with oblique

    The impact of changing climate on terrestrial and underwater archaeological sites, historic buildings, and cultural landscapes can be examined through quantitatively-based analyses encompassing large data samples and broad geographic and temporal scales. The Digital Index of North American Archaeology (DINAA) is a multi-institutional collaboration that allows researchers online access to linked heritage data from multiple sources and data sets. The effects of sea-level rise and concomitant human population relocation is examined using a sample from nine states encompassing much of the Gulf and Atlantic coasts of the southeastern United States. A 1 m rise in sea-level will result in the loss of over >13,000 recorded historic and prehistoric archaeological sites, as well as over 1000 locations currently eligible for inclusion on the National Register of Historic Places (NRHP), encompassing archaeological sites, standing structures, and other cultural properties. These numbers increase substantially with each additional 1 m rise in sea level, with >32,000 archaeological sites and >2400 NRHP properties lost should a 5 m rise occur. Many more unrecorded archaeological and historic sites will also be lost as large areas of the landscape are flooded. The displacement of millions of people due to rising seas will cause additional impacts where these populations resettle. Sea level rise will thus result in the loss of much of the record of human habitation of the coastal margin in the Southeast within the next one to two centuries, and the numbers indicate the magnitude of the impact on the archaeological record globally. Construction of large linked data sets is essential to developing procedures for sampling, triage, and mitigation of these impacts.

    The aim of present research is to obtain information about archaeological analogous of iron and steel, useful for the model of deep geological repository (AGP). The analogous examined have remained buried between 1400 and 2400 years, in very assorted geochemical environments. The extraction of the archaeological pieces has been accomplished according to normalised protocols, trying to carry to the laboratory so the piece as its burial environment, avoiding all possible pollution. Trying to the archaeological analogous could provide valuable information to the AGP model, the study has been directed to related the physical-chemical characteristics of the terrain respect to the deterioration of the archaeological metallic piece. The geology of the surrounding terrain to the archaeological deposit, the geomorphological study of the terrain and data from the analysis of ground: pH, wetness, porosity, organic matter contents, bacteria presence, sulphates, carbonates, chlorides, etc., have allowed to explain the physical-chemical phenomena suffered by the archaeological iron and steel pieces. Also, an exhaustive study of the archaeological piece has been accomplished, concerning the microstructure of the corrosion layer and of the not deteriorated metallic rest. Obtained information concerns different items, such as corrosion velocity and formations of oxide layers, diffusion of chemical elements from the corrosion layer to the metal and viceversa, and structural changes in oxide layers and in the metallic remains by structural ageing. Obtained data have allowed to develop a mathematical model for calculation of corrosion velocity in buried iron and steels, based on physical-chemical variables of grounds, chemical composition and thermomechanical treatment given to the metal during its manufacture.

  17. Is Question-driven Fieldwork Vital or not? An Archaeological Heritage Manager's Perspective

    Directory of Open Access Journals (Sweden)

    Agnieszka Oniszczuk

    2018-03-01

    Full Text Available This article is a follow-up to discussions held in the EAC Heritage Symposiums, and aims to answer one of the basic questions regarding the reasons for commencing any archaeological fieldwork. The subject is approached from the archaeological heritage manager's viewpoint, and question-driven fieldwork is understood here as scientific, as opposed to preventive and development-led archaeology. Basing my arguments mainly on the experiences of Polish archaeology, I argue in favour of the development-led research. It has been shaping European archaeology to the highest degree for several decades, and therefore should not be considered inferior or secondary. Considering the quality gap between purely scientific and development-led fieldwork, there is still a lot to be improved regarding the scope of research and its standards. Nevertheless, it still seems to have the highest potential for systemic heritage management consistent with the rules set out by the Valletta Convention and the Lausanne Charter (PDF, and for the development of archaeology as a science. Development-led archaeology is also the closest to the public and forces archaeologists to cooperate with various stakeholders.

  18. 3D Virtual Dig: a 3D Application for Teaching Fieldwork in Archaeology

    2012-12-01

    Full Text Available Archaeology is a material, embodied discipline; communicating this experience is critical to student success. In the context of lower-division archaeology courses, the present study examines the efficacy of 3D virtual and 2D archaeological representations of digs. This presentation aims to show a 3D application created to teach the archaeological excavation process to freshmen students. An archaeological environment was virtually re-created in 3D, and inserted in a virtual reality software application that allows users to work with the reconstructed excavation area. The software was tested in class for teaching the basics of archaeological fieldwork. The application interface is user-friendly and especially easy for 21st century students. The study employed a pre-survey, post-test, and post-survey design, used to understand the students' previous familiarity with archaeology, and test their awareness after the use of the application. Their level of knowledge was then compared with that of those students who had accessed written material only. This case-study demonstrates how a digital approach to laboratory work can positively affect student learning. Increased abilities to complete ill-defined problems (characteristic of the high-order thinking in the field, can, in fact, be demonstrated. 3D Virtual reconstruction serves, then, as an important bridge from traditional coursework to fieldwork.

  19. New perspectives for satellite-based archaeological research in the ancient territory of Hierapolis (Turkey

    Full Text Available This paper deals with the use of satellite QuickBird images to find traces of past human activity in the ancient territory of Hierapolis (Turkey. This is one of the most important archaeological sites in Turkey, and in 1988 it was inscribed in the UNESCO World Heritage list. Although over the years the archaeological site of Hierapolis has been excavated, restored and well documented, up to now the territory around the ancient urban area is still largely unknown. The current research project, still in progress, aims to search the area neighbouring Hierapolis believed to have been under the control of the city for a long time and, therefore, expected to be very rich in archaeological evidence. In order to investigate a large area around the ancient Hierapolis and discover potential archaeological remains, QuickBird images were adopted.

    Results from satellite-based analysis allowed us to find several unknown rural settlements dating back to early Imperial Roman and the Byzantine age. Two significant test sites were focused on in this paper in order to characterize the different spectral responses observed for different types of archaeological features (shadow and soil marks. Principal Component Analysis and spectral indices were computed to enhance archaeological marks and make identification easier. The capability of the QuickBird data set (panchromatic, multispectral channel, PCA and spectral indices in searching for archaeological marks was assessed in a quantitative way by using a specific indicator.

    2015-01-01

    Full Text Available This work seeks to review soil scientific methods that have been used and are still being used in archaeology. This review paper aims at emphasising the importance of soil science practice to archaeology thus adding a scientific analytical nature to the cultural nature of archaeology. Common methods (physical, chemical and biochemical used to analyse archaeological soils and artefacts is touched on and their strengths and shortcomings duly noted to become the base for future research. Furthermore, the authors made emphasis on distinctive excavating/sampling methods, biochemical analyses focused on distinctive features of plough-land and soil organic matter mineralization, Counter Immunoelectrophoresis (CEIP method by the presence of proteins testing, carbon analyses such as carbon-14 dating techniques, soil phosphorus studies and geochemical analyses of hematite Fe2O3 and cinnabaryte HgS contents. It is obvious that, the future of archaeology is in the soil because the soil harbours information of the past hence the synergy between soil and archaeological research has to be strengthened and archaeology made a prime agenda by soil scientists by expanding the analyses scope of total phosphorus extraction and giving attention to soil magnetism.

    Bone tissue is mineralized dense connective tissue consisting mainly of a mineral component (hydroxyapatite) and an organic matrix comprised of collagens, non-collagenous proteins and proteoglycans (PGs). Extracellular matrix proteins and PGs bind tightly to hydroxyapatite which would protect these molecules from the destructive effects of temperature and chemical agents after death. DNA and proteins have been successfully extracted from archaeological skeletons from which valuable information has been obtained; however, to date neither PGs nor glycosaminoglycan (GAG) chains have been studied in archaeological skeletons. PGs and GAGs play a major role in bone morphogenesis, homeostasis and degenerative bone disease. The ability to isolate and characterize PG and GAG content from archaeological skeletons would unveil valuable paleontological information. We therefore optimized methods for the extraction of both PGs and GAGs from archaeological human skeletons. PGs and GAGs were successfully extracted from both archaeological human bones and teeth, and characterized by their electrophoretic mobility in agarose gel, degradation by specific enzymes and HPLC. The GAG populations isolated were chondroitin sulfate (CS) and hyaluronic acid (HA). In addition, a CSPG was detected. The localization of CS, HA, three small leucine rich PGs (biglycan, decorin and fibromodulin) and glypican was analyzed in archaeological human bone slices. Staining patterns were different for juvenile and adult bones, whilst adolescent bones had a similar staining pattern to adult bones. The finding that significant quantities of PGs and GAGs persist in archaeological bones and teeth opens novel venues for the field of Paleontology.

  2. Animated GIFs as Expressive Visual Narratives and Expository Devices in Archaeology

    2017-06-01

    Full Text Available Animated GIFs are uncommonly well suited for representing archaeology. A shudder-start, temporally ambiguous fragment of sequential media, the animated GIF (just GIFs, hereafter occupies the margins of formal discourse, visually annotating everyday life on the Internet. The creation of a GIF – compiling frames of action into a sequence – draws an easy parallel with the mode of atomizing that characterises excavation, treating archaeological deposits as discrete entities and their subsequent reassembly into a stratigraphic sequence (Morgan 2012; Morgan and Wright in press. Complex cultural expression is distilled into a brief gesture, the digital equivalent of an archaeological trace. Yet GIFs are fleetingly rare in archaeological representations, with only a handful of examples since the introduction of the media format in 1989. In this GIF essay (modelled on a photo essay, we briefly review the history of the animated GIF with particular attention to archaeological GIFs, discuss their utility in representing archaeological remains and narratives, and argue for a more creative integration of visual media into archaeological practice.

    1998-01-01

    The aim of this work is to contribute to the research in the reconstruction of part of the pre-history of the Amazon Basin by means of an analytical methods combined with multivariate analysis, given a analytic basis that can be continued by the archaeological work, through the identification, classification, provenance and dating the ceramics found in different archaeological sites of the Hydro graphic Basin of the Purus river. Neutron activation analysis in conjunction multivariate statistical methods were used for the identification and classification and thermoluminescence was used for the dating. Chemical composition results were in better agreement with archaeological classification for the archaeologically define Iquiri, Quinan and Xapuri phases and less characteristics the Iaco and Jacuru archaeological phase were not well characterized. An homogeneous group was established by most of the samples collected from the Los Angeles Archaeological Site (LA) and was distinct from all the other groups analysed. The provenance studies made with ceramics collected at this site shows that they were made with clay from nearby river (Rio Ina). From the LA ceramics dating the average date of site occupation was 1660 years. The ceramic dating results from the external wall of a circular earth wall construction confirm the relation with the local pre-history. Beyond the Acre material two urns were dated from the Archaeological Site Morro Grande and Sao Jose at Araruama, Rio de Janeiro. (author)

    2002-01-01

    The aim of this work was to use the nuclear methodology to character pottery discovered inside archaeological sites recognized with circular earth structure in Acre State - Brazil which may contribute to the research in the reconstruction of part of the pre-history of the Amazonic Basin. The sites are located mainly in the Hydrographic Basin of High Purus River. Three of them were strategic chosen to collect the ceramics: Lobao, in Sena Madureira County at north; Alto Alegre in Rio Branco County at east and Xipamanu I, in Xapuri County at south. Neutron Activation Analysis in conjunction with multivariate statistical methods were used for the ceramic characterization and classification. An homogeneous group was established by all the sherds collected from Alto Alegre and was distinct from the other two groups analyzed. Some of the sherds collected from Xipamunu I appeared in Lobao's urns, probably because they had the same fabrication process. (author)

  6. Preliminary Simulation of the Corrosion Rate of Archaeological Glass

    Energy Technology Data Exchange (ETDEWEB)

    Steefel, Carl

    2014-01-06

    In this study, we make use of a micro-continuum modeling approach (the Kinetic-Microscopic-Continuum Model or K{micro}C model) to capture the spatial distribution and identity of reaction products developing over time as a result of the archaeological glass corrosion, while also matching the time scales of alteration where possible. Since the glass blocks sat on the Mediterranean seafloor for 1800 years, the physical and chemical boundary conditions are largely constant. We focus on a fracture within the glass block identified by Verney-Carron et al. (2008) and simulate it as a 1D system, with a fixed concentration (Dirichlet) boundary corresponding to the interior of the fracture.

    Directory of Open Access Journals (Sweden)

    Prentiss de JESUS

    2015-12-01

    Full Text Available Geological and archaeological research on ancient mining and metallurgy are actually targeting the same goals: understanding the nature and value of a mining operation. Geologists are intent on locating and qualifying ores and minerals for future use, whereas archaeologists strive to link ores to relevant historic and prehistoric metal artifacts and activities. This article discusses research into ancient Anatolian metallurgy by underscoring the overlap between geological and archeological practices. The work of archaeologists and geologists can be mutually beneficial through a close collaboration on the collection and analysis of field data. Their accumulated and combined knowledge would accelerate the progress towards placing ancient mining activities in a chronological and meaningful context.

    This paper describes the neutron tomography investigation on archaeological artifacts from museums in South Africa. While X-rays fail to penetrate the brass matrix of the samples, neutrons can easily reveal, on a non-invasive manner, the content and structure of these precious samples. The South African Neutron Radiography (SANRAD) facility, located at the SAFARI-1 nuclear research reactor, operated by Necsa near Pretoria, South Africa, was utilized in a tomography mode during the investigations. For the 3D tomographical reconstruction of the sample, 375 projections were collected while the sample was rotated around a defined axis through 360 deg. rotation interval. The results show that the technique is able to reconstruct structural features very well and in particular, highly absorbing zones and the presence of defects in the bulk. The samples originate from collections at museums in South Africa and these investigations were the first of its kind performed in the country.

    In this paper, we report the first investigation on the potentials of neutron diffraction to characterize archaeological bronze artifacts. The preliminary feasibility of phase and structural analysis was demonstrated on standardised specimens with a typical bronze alloy composition. These were realised through different hardening and annealing cycles, simulating possible ancient working techniques. The Bragg peak widths that resulted were strictly dependent on the working treatment, thus providing an important analytical element to investigate ancient making techniques. The diagnostic criteria developed on the standardised specimens were then applied to study two Etruscan museum pieces. Quantitative multiphase analysis by Rietveld refinement of the diffraction patterns was successfully demonstrated. Furthermore, the analysis of patterns associated with different artifact elements also yielded evidence for some peculiar perspective of the neutron diffraction diagnostics in archeometric applications.

    Analytical work on material of archaeological interest performed at LARN mainly concerns gold jewellery, with an emphasis to solders on the artefacts and to gold plating or copper depletion gilding. PIXE, RBS but also PIGE and NRA have been applied to a large variety of items. On the basis of elemental analysis, we have identified typical workmanship of ancient goldsmiths in various regions of the world: finely decorated Mesopotamian items, Hellenistic and Byzantine craftsmanship, cloisonne of the Merovingian period, depletion gilding on Pre-Colombian tumbaga. This paper is some shortening of the work performed at LARN during the last ten years. Criteria to properly use PIXE for quantitative analysis of non-homogeneous ancient artefacts presented at the 12th IBA conference in 1995 are also shortly discussed. (orig.)

For example, under a historic ‘domestic’ division of labour in archaeology, women have disproportionately performed invisible ‘dishwashing’ duties, which have not only been immediately financially under-rewarding and relatively insecure, but which have also undermined career progression by requiring under-recognised labour such as collection cataloguing (Dommasnes, Kleppe, Mandt and Næss, 1998: 119; see also Bolger, 2003: 207 – tables 8.2–8.3; Webb and Frankel, 1995: 101; Karouzou, 1984: 27, translated and cited by Nikolaidou and Kokkinidou, 1998: 248.

    When discussing the container material for highly active radionuclear waste, carbon steel is one of the materials most frequently proposed by the international scientific community. Evidently, security with respect to the container behaviour into deep geological deposits is fundamental. Among other parameters, knowledge about material mechanical properties is essential when designing the container. Time ageing of carbon steel, apart from possible alterations of the chemical composition (e.g. corrosion) involves important microstructural changes, at the scale of centuries and millenniums. The latter may cause variations of the mechanical properties of carbon steel storage containers, with the corresponding risk of possible leakage. In order to properly estimate such risk and to adjust the corresponding mathematical models to reality, the microstructural changes observed in this study on archaeologic samples are evaluated, comparing ancient and modern steels of similar chemical composition and fabrication processes

    Elemental analysis by X-ray fluorescence and particle induced X-ray emission is applied to the study of several Mesoamerican mural samples containing blue pigments. The most characteristic blue pigment is Maya blue, a very stable organo-clay complex original from Maya culture and widely used in murals, pottery and sculptures in a vast region of Mesoamerica during the pre-hispanic time (from VIII century) and during the colonization until 1580. The mural samples come from six different archaeological sites (four pre-hispanic and two from XVI century colonial convents). The correlation between the presence of some elements and the pigment colour is discussed. From the comparative study of the elemental concentration, some conclusions are drawn on the nature of the pigments and the technology used

    We report on an interdisciplinary approach to the study of early pottery finds from the Poma Archaeological Reserve, North Coast of Peru. The material is from a Formative kiln site at Batán Grande (1000-800 BC) and a ceramics workshop at Huaca Sialupe pertaining to the Middle Sicán period (900-1100 AD). Mössbauer spectroscopy, neutron activation analysis, optical thin-section microscopy and X-ray diffraction were used to characterize the material. Numerous sherds of Sicán black- and redware, bricks, moulds and kiln linings were studied. Local clay from the kiln site at Batán Grande, lumps of clay, and unfired sherds from Huaca Sialupe were used as model material for firing experiments under controlled conditions. By comparing the Mössbauer spectra from laboratory and field firings with the ancient materials, methods of early pottery making can be assessed.

    This paper describes the neutron tomography investigation on archaeological artifacts from museums in South Africa. While X-rays fail to penetrate the brass matrix of the samples, neutrons can easily reveal, on a non-invasive manner, the content and structure of these precious samples. The South African Neutron Radiography (SANRAD) facility, located at the SAFARI-1 nuclear research reactor, operated by Necsa near Pretoria, South Africa, was utilized in a tomography mode during the investigations. For the 3D tomographical reconstruction of the sample, 375 projections were collected while the sample was rotated around a defined axis through 360 deg. rotation interval. The results show that the technique is able to reconstruct structural features very well and in particular, highly absorbing zones and the presence of defects in the bulk. The samples originate from collections at museums in South Africa and these investigations were the first of its kind performed in the country.

    This work presents the results obtained from the characterization of a series of samples belonging to different monuments of the Olmec culture. These monuments are exhibited in the archaeological site of La Venta, Tabasco, Mexico. Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD) were used to determine the crystalline phases that characterise the samples, these phases are associated to different morphology. The elemental analysis exhibits the presence mainly of such elements as C, Si, O, Al, Na, Ca and in less abundance Ti, K, Cr, Ni and Mn were determined. The morphology is characterized by the presence of plane tabular structures, schists, extended slates and clusters of irregular grain. Such crystal phases as anorthite, albite, sanidine, zinnwaldite and clinochlore were identified. These phases are associated with such type of materials as feldspars and mica. All the identified phases are noted for presenting near perfect exfoliation. (Author)
