Engineering assessment of inactive uranium mill tailings: Monument Valley Site, Monument Valley, Arizona

Energy Technology Data Exchange (ETDEWEB)

1981-10-01

Ford, Bacon and Davis Utah Inc. has reevalated the Monument Valley site in order to revise the March 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Monument Valley, Arizona. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposure of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 1.1 million tons of tailings at the Monument Valley site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material (Option I), to removal of the tailings to remote disposal sites and decontamination of the tailings site (Options II through IV). Cost estimates for the four options range from about $6,600,000 for stabilization in-place, to about $15,900,000 for disposal at a distance of about 15 mi. Three principal alternatives for reprocessing the Monument Valley tailings were examined: heap leaching; Treatment at an existing mill; and reprocessing at a new conventional mill constructed for tailings reprocessing. The cost of the uranium recovery is economically unattractive.

Construction materials (natural stone, aggregates, bricks, cement, lime, mortar, etc.) form a wide and heterogeneous group both from the genetic and technological point of view. These materials deserve attention from the scientific community due to their long-term use, importance for society and sensitivity to the environment. Most geomaterials have also been used in important monuments designated as a part of the World Cultural Heritage and/or make part of national monuments. Despite of the wide-ranges of studies and our rapidly increasing understanding of material behaviour, our knowledge is still rather limited in many aspects. This concerns the characterisation of traditional raw materials, the knowledge of their processing and use, and/or durability and compatibility assessment. The exploitation and sustainable use of these materials are also new and emerging challenges in the modern society. The use of local materials for monuments can be considered as a part of our cultural and technological heritage, which has, however, significantly deteriorated during the past several decades. This paper summarizes the general topics related to a modern analysis of traditional construction materials derived from the Earth, and on the characteristic aspects of the behaviour of these materials on selected monuments.

Resumen

Este artículo aborda el campamento Ocatilla, construido en el  desierto de Arizona por Frank Lloyd Wright como una estación  experimental de arquitectura en 1929. Se propone este campamento como un prototipo que tendría dos vectores  temporales por lo que se refiere a una posible genealogía y a un posible desarrollo futuro. Hacía el pasado habría que  rastrearlo en la Casa para la Familia Cristiana propuesta por  Catherine Beecher en 1869, mientras que hacia el futuro podría establecerse un posible epígono en la Burbuja Ambiental de  Reyner Banham y François Dallegret de 1965. El texto explora  las posibilidades de un ideal de arquitectura para el paisaje monumental, perfectamente ejemplarizado en los tres casos, frente a la arquitectura como monumento ante el paisaje, que ejemplificaría Taliesin West, su monumental contrafigura.

Abstract

This article discusses the Ocatilla camp, built in the Arizona  desert by Frank Lloyd Wright as an experimental architecture in  1929. This camp is proposed as a prototype with two temporary vectors, one would be to a possible genealogy and the other a  possible future development. Going to the past should be traced in the House for the Christian Family by Catherine Beecher proposed in 1869, while that to the future could be made a epigone in the Environmental Bubble of Reyner Banham and of François Dallegret in 1965. The text explores the possibilities of an ideal architecture for the monumental landscape, perfectly  exemplified in the three cases, compared to architecture as a monument to the landscape, which exemplify Taliesin West, his monumental counterpart.

Full Text Available This article examines the Tirana Independence Monument, first inaugurated in November of 2012 on the hundredth anniversary of Albanian independence from the Ottoman Empire. The monument, designed by Visar Obrija and Kai Roman Kiklas, swiftly fell into disrepair until it was recently renovated in November of 2015. The article analyzes the monument’s function in terms of its doubled existence as a sign of perpetual natality (the possibility of the rebirth of national consciousness and as a ruin with a spectral pseudo-presence (as an object that continually reminds us of the disjunctures that divorce the present from its historicity. It considers the way the monument’s inauguration relates to the politics of monumentality in contemporary Albania, and argues that the monument’s gradual ruination between 2012 and 2015 can be read as a particular manifestation of the history of the image in late capitalist society.Keywords: spectrality, natality, monumentality, Albania, Tirana, independence, national identity, grid, public sculpture

Full Text Available Learning the historical value of a monument is important because it preserves cultural and historical values, as well as expanding our personal insight. In Indonesia, particularly in Manado, North Sulawesi, there are many monuments. The monuments are erected for history, religion, culture and past war, however these aren’t written in detail in the monuments. To get information on specific monument, manual search was required, i.e. asking related people or sources. Based on the problem, the development of an application which can utilize LBS (Location Based Service method and some algorithmic methods specifically designed for mobile devices such as Smartphone, was required so that information on every monument in Manado can be displayed in detail using GPS coordinate. The application was developed by KNN method with K-means algorithm and collaborative filtering to recommend monument information to tourist. Tourists will get recommended options filtered by distance. Then, this method was also used to look for the closest monument from user. KNN algorithm determines the closest location by making comparisons according to calculation of longitude and latitude of several monuments tourist wants to visit. With this application, tourists who want to know and find information on monuments in Manado can do them easily and quickly because monument information is recommended directly to user without having to make selection. Moreover, tourist can see recommended monument information and search several monuments in Manado in real time.

Estimation of immune cell densities in immune cell conglomerates: an approach for high-throughput quantification.

Directory of Open Access Journals (Sweden)

Niels Halama

2009-11-01

Full Text Available Determining the correct number of positive immune cells in immunohistological sections of colorectal cancer and other tumor entities is emerging as an important clinical predictor and therapy selector for an individual patient. This task is usually obstructed by cell conglomerates of various sizes. We here show that at least in colorectal cancer the inclusion of immune cell conglomerates is indispensable for estimating reliable patient cell counts. Integrating virtual microscopy and image processing principally allows the high-throughput evaluation of complete tissue slides.For such large-scale systems we demonstrate a robust quantitative image processing algorithm for the reproducible quantification of cell conglomerates on CD3 positive T cells in colorectal cancer. While isolated cells (28 to 80 microm(2 are counted directly, the number of cells contained in a conglomerate is estimated by dividing the area of the conglomerate in thin tissues sections (< or =6 microm by the median area covered by an isolated T cell which we determined as 58 microm(2. We applied our algorithm to large numbers of CD3 positive T cell conglomerates and compared the results to cell counts obtained manually by two independent observers. While especially for high cell counts, the manual counting showed a deviation of up to 400 cells/mm(2 (41% variation, algorithm-determined T cell numbers generally lay in between the manually observed cell numbers but with perfect reproducibility.In summary, we recommend our approach as an objective and robust strategy for quantifying immune cell densities in immunohistological sections which can be directly implemented into automated full slide image processing systems.

Vascular Plant and Vertebrate Inventory of Chiricahua National Monument

Powell, Brian F.; Schmidt, Cecilia A.; Halvorson, William L.; Anning, Pamela

2009-01-01

This report summarizes the results of the first comprehensive inventory of vascular plants and vertebrates at Chiricahua National Monument (NM) in Arizona. This project was part of a larger effort to inventory vascular plants and vertebrates in eight National Park Service units in the Sonoran Desert Network of parks in Arizona and New Mexico. In 2002, 2003, and 2004 we surveyed for plants and vertebrates (amphibians, reptiles, birds, and mammals) at Chiricahua NM to document the presence of species within the boundaries of the monument. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the monument. This report is also the first summary of previous research from the monument and therefore it provides an important overview of survey efforts to date. We used data from our inventory and previous research to compile complete species lists for the monument and to assess inventory completeness. We recorded a total of 424 species, including 37 not previously found at the monument (Table 1). We found 10 species of non-native plants and one non-native mammal. Most non-native plants were found along the western boundary of the monument. Based on a review of our inventory and past research at the monument, there have been a total of 1,137 species of plants and vertebrates found at the monument. We believe the inventories of vascular plants and vertebrates are nearly complete and that the monument has one of the most complete inventories of any unit in the Sonoran Desert Network. The mammal community at the monument had the highest species richness (69 species) and the amphibian and reptile community was among the lowest species richness (33 species) of any park in the Sonoran Desert Network. Species richness of the plant and bird communities was intermediate. Among the important determinants of species richness for all groups is the geographic location of the monument

The Monumental Task of Warning Future Generations

NA

2005-01-01

Describing preliminary concepts for permanent warning monuments or markers on the mountain's surface will be part of the US Department of Energy's license application to the Nuclear Regulatory Commission (NRC) for a proposed repository at Yucca Mountain, Nevada. The NRC requires that the monuments or markers accurately identify the location of the repository, be designed to be as permanent as practicable and convey a warning against intrusion into the underground repository, because of risk to public health and safety from radioactive wastes. Current concepts include both monuments and markers, but the designs will not be final for some time because they will not be approved by the NRC until shortly before the repository is to be permanently sealed and closed. Closure of the repository would be at least 50 years, and possibly up to 300 years, after the first waste is emplaced deep underground. Design ideas for the monuments and markers have been drawn from a broad range of sources: Yucca Mountain's natural conditions, worldwide archeological studies, materials science, and verbal and symbolic linguistics. The monumental challenge is to address how warnings can be coherently conveyed for thousands of years into the future when human society and languages could change radically

Majid, Z.; Lau, C. L.; Yusoff, A. R.

2016-06-01

This paper describes the use of terrestrial laser scanning for the full three-dimensional (3D) recording of historical monument, known as the Bastion Middleburg. The monument is located in Melaka, Malaysia, and was built by the Dutch in 1660. This monument serves as a major hub for the community when conducting commercial activities in estuaries Malacca and the Dutch build this monument as a control tower or fortress. The monument is located on the banks of the Malacca River was built between Stadhuys or better known as the Red House and Mill Quayside. The breakthrough fort on 25 November 2006 was a result of the National Heritage Department through in-depth research on the old map. The recording process begins with the placement of measuring targets at strategic locations around the monument. Spherical target was used in the point cloud data registration. The scanning process is carried out using a laser scanning system known as a terrestrial scanner Leica C10. This monument was scanned at seven scanning stations located surrounding the monument with medium scanning resolution mode. Images of the monument have also been captured using a digital camera that is setup in the scanner. For the purposes of proper registration process, the entire spherical target was scanned separately using a high scanning resolution mode. The point cloud data was pre-processed using Leica Cyclone software. The pre-processing process starting with the registration of seven scan data set through overlapping spherical targets. The post-process involved in the generation of coloured point cloud model of the monument using third-party software. The orthophoto of the monument was also produced. This research shows that the method of laser scanning provides an excellent solution for recording historical monuments with true scale of and texture.

Conglomerate memory and cosmopolitanism

Susannah Ryan

2016-01-01

Full Text Available Under what conditions do countries and cultures considered radically different find a basis for allegiance and kinship? What part does memory play in this process? This article responds to these questions in two ways: 1 Through Emmanuel Levinas and Hannah Arendt, I propose that when an other appears in empathetic discourses that both honor difference and cite shared human experiences, seemingly irreconcilable people can develop a sense of mutual responsibility and 2 Conglomerate memory, memories that fuse together others through common pains, contributes to such an appearance. To illustrate this point, I turn to Congolese voices as they are articulated in online American discourses; although currently, authors of online texts typically rely on traditional narrative forms that position Central Africa as incommensurate to Western civilizations, the Internet's worldwide accessibility and intertextual capacities render it a place primed for developing international collectives by connecting memories while maintaining difference.

Geological and Hydrodynamical Examination of the Bathyal Tsunamigenic Origin of Miocene Conglomerates in Chita Peninsula, Central Japan

2011-06-01

A conglomerate appears on a rocky coast called "Tsubutega-ura Coast", located on the southwestern coast near the southern tip of the Chita Peninsula, Aichi Prefecture, central Japan. The conglomerate belongs to Miocene sedimentary rocks termed the Morozaki Group. The conglomerate includes meter-scale boulders, indicating that it was formed by an extraordinary event. In the geological investigation, we observed that the conglomerate shows alternate changes of paleocurrent directions between seaward and landward. This feature is supposed to be formed by tsunami currents. In the hydrodynamical investigation, we obtained following results: (1) the lowest limit of a current velocity to move a boulder of about 3 m in diameter would be about 2-3 m/s, (2) the speed of tsunami currents reproduced by tsunami simulation exceeds 3 m/s at 300 m in depth when the tsunami is generated by a gigantic earthquake with magnitude 9.0 or more, (3) the transport distance of the boulder would be several hundred meters to several kilometers by one tsunami event caused by a gigantic earthquake. We conclude that tsunamis best explain the formation of the conglomerate deposited in upper bathyal environments about 200-400 m depth, both from geological and hydrodynamical viewpoints.

Full Text Available Udin Boršt is a karstified terrace of carbonate rock, which is of fluvioglacial origin, and is situated in the north-western part of Slovenia. There are 15 registered caves, which have been interpreted as caves in conglomerate, while karst of Udin Boršt itself was interpreted as conglomerate karst, shallow karst or isolated karst. In this article, caves in Udin Boršt have been interpreted as eogenetic caves. Based on porosity and bedding material, different types of caves and cave passages have developed. Four general types of eogenetic caves found in Udin Boršt are; linear stream caves, shelter caves, breakdown caves and vadose shafts.

Vascular Plant and Vertebrate Inventory of Organ Pipe Cactus National Monument

Schmidt, Cecilia A.; Powell, Brian F.; Halvorson, William L.

2007-01-01

Executive Summary We summarized inventory and monitoring efforts for plants and vertebrates at Organ Pipe Cactus National Monument (NM) in Arizona. We used data from previous research to compile complete species lists for the monument and to assess inventory completeness. There have been 1,031 species of plants and vertebrates observed at the monument. Most of the species on the list are documented by voucher specimens. There are 59 non-native species established in the monument: one mammal, three birds, and 55 non-native plants. Most non-native plant species were first recorded along roads. In each taxon-specific chapter, we highlight areas that contribute disproportionately to species richness or that have unique species for the monument. Of particular importance are Quitobaquito Springs and Pond, which are responsible for the monument having one of the highest number of bird species in the Sonoran Desert Network of parks. Quitobaquito also contains the only fish in the monument, the endangered Quitobaquito pupfish (Cyprinodon eremus). Other important resources for the plants and vertebrates include the xeroriparian washes (e.g., Alamo Canyon) and the Ajo Mountains. Based on the review of past studies, we believe the inventories of vascular plants and vertebrates are nearly complete and that the monument has one of the most complete inventories of any unit in the Sonoran Desert Network.

Summary of the engineering assessment of inactive uranium mill tailings: Monument Valley site, Monument Valley, Arizona

1981-10-01

Ford, Bacon and Davis Utah Inc. has reevaluated the Monument Valley site in order to revise the March 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Monument Valley, Arizona. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 1.1 million tons of tailings at the Monument Valley site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover material to removal of the tailings to remote disposal sites and decontamination of the tailings site. Cost estimates for the four options range from about $6,600,000 for stabilization in-place, to about $15,900,000 for disposal at a distance of about 15 mi. Three principal alternatives for reprocessing the Monument Valley tailings were examined: heap leaching, treatment at an existing mill; and reprocessing at a new conventional mill constructed for tailings reprocessing. The cost of the uranium recovered would be more than $500/lb of U 3 O 8 by heap leach or conventional plant processes. The spot market price for uranium was $25/lb early in 1981. Therefore, reprocessing the tailings for uranium recovery is economically unattractive

Antoszczyszyn, Marek

2017-10-01

The paper discusses a controversy surrounding the latest amendment to the text of the Polish Parliament Act Conservation and the Care of Monuments (2015). It is a common dictum that any edifice cannot exist without good foundations. In this particular case of the mentioned above Act, definition of monument appears to be such a basis. A social interest is one of the constituent elements of the definition mentioned above. In the first part of the paper the notion of the social interest expression has been discussed, particularly from national and international points of view. The second part of the paper comprises some examples from the Polish monument preservation experience with the use of comparison method supported by case study. Only three big Polish cities: Warsaw, Wroclaw and Szczecin are involved in the presented case study but it must be emphasized that many other places on Polish territory experienced the same. Basing on the faith of these cities, the results and discussion chapter proves fundamental discrepancy in social interest notion between national and international scopes using some analytical methods. Finally, in the discussion chapter some proposals for the future amendment of monument definition in the Act of Conservation and the Care of Monuments have been provided.

Full Text Available The article examines the causes and origins of the all-Russian society for protection of monuments of history and culture. On the basis of archival documents the author shows the appearance of the Volgograd branch of all-Russian society of protection of monuments of history and culture. The author describes its activities on studying, preserving and promoting the monuments of history and culture of the Volgograd region in the 1970s. The author discusses the causes of establishing in 1974 the section of the regional Department for the protection and promotion of monuments of labour glory of the Soviet people. He indicates that its appearance in the structure of all-Russian society of protection of monuments of history and culture was associated with an increased conducted by the then government work on military-Patriotic education of youth. Under this policy, the section has been considered from the point of view of propaganda of Soviet history and focused on the identification, promotion and protection of monuments of history of Soviet society. The article studies its activities related to the identification, research, description, and preservation of monuments of labour achievements of the Soviet period. The author indicates the difficulties encountered after the adoption in 1976 of the USSR Law “On the protection and use of monuments of history and culture”, where the monuments of labour glory in a separate category werenot distinguished and were classified as historical monuments. The author describes the closure of the section of monuments to the labour of fame in 1979 and evaluates the results of the section, its contribution to the preservation of the cultural heritage of the Volgograd region.

Accessibility improvement interventions realised in Byzantine monuments of Thessaloniki, Greece

Directory of Open Access Journals (Sweden)

Aristotelis Naniopoulos

2015-10-01

Full Text Available Purpose – Access to culture is a fundamental right of people with disabilities and a significant aspect in the development of accessible tourism. A visit to a monument provides an authentic experience which cannot be substituted by any representation. However, any interventions to improve accessibility should be made carefully, so as not to alter the monument�s character, or damage it visually or structurally. The paper aims to discuss these issues. Design/methodology/approach – A theoretical approach model was defined in the PROSPELASIS project for the improvement of accessibility in monuments which was applied in Byzantine monuments of Thessaloniki. This approach contains the following steps: evaluation of existing accessibility level; definition of alternative solutions; creation of final studies, approval by archaeological authorities and implementation of interventions. Findings – In six major Byzantine monuments significant improvements were realized which include: installation of two lifts and creation of a new staircase at Acheiropoietos; creation of a metal bridge, a new staircase and installation of a lift at Rotunda; opening of the secondary gate and creation of a ramp at the Heptapyrgion fortress; creation of an accessible toilet at the Saint Demetrios church; installation in the six monuments of a WiFi system providing text and audible information as well as information in Greek and International Sign Language; creation of two tactile models; creation of a �cultural route� connecting three major Byzantine monuments. Originality/value – For the first time, to the knowledge, a set of interventions has been realized in Byzantine monuments focusing on various categories of people with disabilities, i.e. motor, visual, hearing and cognitive.

Actins, A.; Spricis, A.; Zekunde, A.; Nemerova, A.

2004-01-01

By means of x-ray analysis composition of stone and stone surface materials of historical monuments from Vidzeme and Zemgale was investigated. Corrosion products of tuffa materials were identified on surfaces of some investigated monuments. Similarity of composition of products of stone corrosion for monuments from Latvia and Poland was recognised. Content of heavy metals at stone materials of historical monuments and at the surface layers of these monuments was investigated by means of atomic absorption and potentiometric stripping methods. Reasons of formation of compounds and pollution of investigated samples were discussed. (full text)

Ultrastructure and electrophoretic protein pattern of a nuclear fraction enriched in interchromatin granule conglomerations

Energy Technology Data Exchange (ETDEWEB)

Krzyzowska-Gruca, S.; Zborek, A.; Gruca, S.

1986-01-01

Rats were injected with a cytostatic 1-nitro-9/3'-dimethylpropyloamine/acridine.2HCl to induce aggregation of interchromatin granules (IG). The conglomerations of IG were well preserved in isolated liver nuclei and in nuclear structures deprived of chromatin. This feature enabled obtaining a nuclear fraction enriched in IG. The method consisted in extraction of isolated nuclei with a non-ionic detergent and digestion with DNase I in a high ionic strength. Each step of isolation was ultrastructurally monitored using both the routine electron microscopy as well as a preferential staining of IG with bismuth. Presence of spots of tightly packed granules within IG conglomerations in the final fraction like in the nuclei in situ was a good ultrastructural marker of IG. The resulting fraction consisted predominantly of IG conglomerations. Their preferential staining with bismuth was well preserved. Minute amounts of fibrillar material originating from nuclear matrix and residual nuclei could be observed. Protein composition of the fraction enriched in IG was studied by SDS-polyacrylamide gel electrophoresis. After electrotransfer, nitrocellulose filters were fixed with glutaraldehyde and stained with bismuth method in order to identify IG proteins. The results of ultrastructural and cytochemical studies in comparison to electrophoretic protein pattern are discussed.

Uranium deposits in Proterozoic quartz-pebble conglomerates

International Nuclear Information System (INIS)

1987-09-01

This report is the result of an effort to gather together the most important information on uranium deposits in Proterozoic quartz-pebble conglomerates in the United States of America, Canada, Finland, Ghana, South Africa and Australia. The paper discusses the uranium potential (and in some cases also the gold potential in South Africa, Western Australia and Ghana) in terms of ores, sedimentation, mineralization, metamorphism, placers, geologic formations, stratigraphy, petrology, exploration, tectonics and distribution. Geologic history and application of geologic models are also discussed. Glacial outwash and water influx is also mentioned. The uranium deposits in a number of States in the USA are covered. The Witwatersrand placers are discussed in several papers. Refs, figs, tabs

Geology and recognition criteria for uranium deposits of the quartz-pebble conglomerate type. Final report

Energy Technology Data Exchange (ETDEWEB)

Button, A.; Adams, S.S.

1981-03-01

This report is concerned with Precambrian uraniferous conglomerates. This class of deposit has been estimated to contain between approximately 16 and 35 percent of the global uranium reserve in two rather small areas, one in Canada, the other in South Africa. Similar conglomerates, which are often gold-bearing, are, however, rather widespread, being found in parts of most Precambrian shield areas. Data have been synthesized on the geologic habitat and character of this deposit type. The primary objective has been to provide the most relevant geologic observations in a structural fashion to allow resource studies and exploration to focus on the most prospective targets in the shortest possible time.

A Monument as a Text, or The Message of the Brothers Dostoevsky

Directory of Open Access Journals (Sweden)

Vladimir Zakharov

2014-12-01

Full Text Available The article considers the circumstances of the creation of a monument to the writer's mother Maria Fyodorovna Dostoevskaya. Mikhail Andreevich, father of the brothers Dostoevsky, asked Mikhail and Fyodor to compose the text for the monument. In March and April of 1837 the brothers worked out the idea and conception of the monument, wrote the text of the first and fourth epigraphs, chose evangelic verses and an epitaph of N.M. Karamzin. This was their first collective act of creative work embodied in stone. The monument is not only a symbol of love and sorrow for their mother’s death but also hope for her salvation and future resurrection. The brothers’ words and those chosen from the Gospel as well as the Karamzin’s ones have one more meaning. These convey a sense of beingness and an Easter idea of individual creative work. It is necessary to renew the tomb of Maria Fyodorovna Dostoevskaya and bring the monument back to Lazarevskoye cemetery in Moscow.

National Uranium Resource Evaluation. Volume 1. Summary of the geology and uranium potential of Precambrian conglomerates in southeastern Wyoming

A series of uranium-, thorium-, and gold-bearing conglomerates in Late Archean and Early Proterozoic metasedimentary rocks have been discovered in southern Wyoming. The mineral deposits were found by applying the time and strata bound model for the origin of uranium-bearing quartz-pebble conglomerates to favorable rock types within a geologic terrane known from prior regional mapping. No mineral deposits have been discovered that are of current (1981) economic interest, but preliminary resource estimates indicate that over 3418 tons of uranium and over 1996 tons of thorium are present in the Medicine Bow Mountains and that over 440 tons of uranium and 6350 tons of thorium are present in Sierra Madre. Sampling has been inadequate to determine gold resources. High grade uranium deposits have not been detected by work to date but local beds of uranium-bearing conglomerate contain as much as 1380 ppM uranium over a thickness of 0.65 meters. This project has involved geologic mapping at scales from 1/6000 to 1/50,000 detailed sampling, and the evaluation of 48 diamond drill holes, but the area is too large to fully establish the economic potential with the present information. This first volume summarizes the geologic setting and geologic and geochemical characteristics of the uranium-bearing conglomerates. Volume 2 contains supporting geochemical data, lithologic logs from 48 drill holes in Precambrian rocks, and drill site geologic maps and cross-sections from most of the holes. Volume 3 is a geostatistical resource estimate of uranium and thorium in quartz-pebble conglomerates.

Precambrian uranium-bearing quartz-pebble conglomerates: exploration model and United States resource potential

International Nuclear Information System (INIS)

Houston, R.S.; Karlstrom, K.E.

1979-11-01

Uranium has been discovered in fluvial quartz-pebble conglomerates in most of the Precambrian shield areas of the world, including the Canadian, African, South American, Indian, Baltic, and Australian shields. Occurrences in these and other areas are shown. Two of these occurrences, the Huronian supergroup of Canada and the Witwatersrand deposit of South Africa contain 20 to 30 percent of the planet's known uranium reserves. Thus it is critical that we understand the origin of these deposits and develop exploration models that can aid in finding new deposits. Inasmuch as these uranium-bearing conglomerates are confined almost entirely to rocks of Precambrian age, Part I of this review begins with a discussion of Precambrian geology as it applies to the conglomerates. This is followed by a discussion of genetic concepts, a discussion of unresolved problems, and finally a suggested exploration model. Part II summarizes known and potential occurrences of Precambrian fossil placers in the world and evaluates them in terms of the suggested exploration model. Part III discusses the potential for important Precambrian fossil-placer uranium deposits in the United States and includes suggestions that may be helpful in establishing an exploration program in this country. Part III also brings together new (1975-1978) data on uranium occurrences in the Precambrian of the Wyoming Province. Part IV is a complete bibliography of Precambrian fossil placers, divided according to geographical areas. In total, this paper is designed to be a comprehensive review of Precambrian uranium-bearing fossil placers which will be of use to uranium explorationists and to students of Precambrian geology

The host rock at the Coronation Hill U-Au mine is a debris flow conglomerate, developed in a high-energy fluvial environment during deposition of the Coronation Sandstone of the El Sherana Group. Mineralisation took place by movement of low-temperature fluids from the U-enriched volcanics into the conduit sandstone and eventually into the reduced debris flow conglomerate and carbonaceous shale

Relationships between the Brook Street Terrane and Median Tectonic Zone (Median Batholith) : evidence from Jurassic conglomerates

U-Pb zircon ages of 237-180 Ma and c. 280 Ma of seven granitoid clasts from the Rainy River Conglomerate which lies within the eastern Median Tectonic Zone (Median Batholith) in Nelson, and the Barretts Formation of the Brook Street Terrane in Southland, constrain the depositional ages of both units to be no older than c. 180-200 Ma (Early Jurassic). The minimum age of the Rainy River Conglomerate is constrained by the 147 +2 -1 Ma (Latest Jurassic) emplacement age of the One Mile Gabbronorite (new name: previously western Buller Diorite). The ages and chemistry of five of the granitoid clasts are broadly compatible with derivation from rocks that are now represented by Triassic plutons of the Median Tectonic Zone (Median Batholith), although ages as young as 180 Ma are slightly outside the range of the latter as currently exposed in New Zealand. The age (273-290 Ma, 237 +/- 3 Ma) and chemistry of the other two clasts (one each from Rainy River Conglomerate and Barretts Formation) suggest derivation from the Brook Street Terrane. Similarity in stratigraphic age, depositional characteristics, granitoid clast ages and composition between Rainy River Conglomerate and Barretts Formation suggests that they are broadly correlative and collectively overlapped a combined Brook Street Terrane - Median Batholith (MTZ) before the Late Jurassic (147 +2 -1 Ma). Sedimentary overlap may also have continued across to Middle Jurassic conglomeratic strata in the Murihiku Terrane to the east of the Brook Street Terrane. A U-Pb zircon age of 261 +/- 2 Ma is reported for Pourakino Trondhjemite of the Brook Street Terrane. (author). 56 refs., 10 figs., 4 tabs

In this study, aerosol light-absorption measurements obtained at three sites during a winter campaign were used to analyse and identify the major sources of Black Carbon (BC) particles in and around the Alhambra monument, a UNESCO World Heritage Site that receives over 2 million visitors per year. The Conditional Bivariate Probability Function and the Aethalometer model were employed to identify the main sources of BC particles and to estimate the contributions of biomass burning and fossil fuel emissions to the total Equivalent Black Carbon (EBC) concentrations over the monumental complex. Unexpected high levels of EBC were found at the Alhambra, comparable to those measured in relatively polluted European urban areas during winter. EBC concentrations above 3.0 μg/m3, which are associated with unacceptable levels of soiling and negative public reactions, were observed at Alhambra monument on 13 days from 12 October 2015 to 29 February 2016, which can pose a risk to its long-term conservation and may cause negative social and economic impacts. It was found that road traffic emissions from the nearby urban area and access road to the Alhambra were the main sources of BC particles over the monument. However, biomass burning emissions were found to have very small impact on EBC concentrations at the Alhambra. The highest EBC concentrations were observed during an extended stagnant episode associated with persistent high-pressure systems, reflecting the large impact that can have these synoptic conditions on BC over the Alhambra.

Executive Summary This report summarizes results of the first comprehensive biological inventory of Casa Grande Ruins National Monument (NM) in southern Arizona. Surveys at the monument were part of a larger effort to inventory vascular plants and vertebrates in eight National Park Service units in Arizona and New Mexico. In 2001 and 2002 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at Casa Grande Ruins NM to document the presence, and in some cases relative abundance, of species. By using repeatable study designs and standardized field techniques, which included quantified survey effort, we produced inventories that can serve as the basis for a biological monitoring program. Of the National Park Service units in the region, no other has experienced as much recent ecological change as Casa Grande Ruins NM. Once situated in a large and biologically diverse mesquite bosque near the perennially flowing Gila River, the monument is now a patch of sparse desert vegetation surrounded by urban and commercial development that is rapidly replacing agriculture as the dominant land use in the area. Roads, highways, and canals surround the monument. Development, and its associated impacts, has important implications for the plants and animals that live in the monument. The plant species list is small and the distribution and number of non-native plants appears to be increasing. Terrestrial vertebrates are also being impacted by the changing landscape, which is increasing the isolation of these populations from nearby natural areas and thereby reducing the number of species at the monument. These observations are alarming and are based on our review of previous studies, our research in the monument, and our knowledge of the biogeography and ecology of the Sonoran Desert. Together, these data suggest that the monument has lost a significant portion of its historic complement of species and these changes will likely intensify as

Schmidt, Cecilia A.; Drost, Charles A.; Halvorson, William Lee

2006-01-01

Executive Summary We summarize past inventory efforts for vascular plants and vertebrates at Montezuma Castle National Monument (NM) in Arizona. We used data from previous research to compile complete species lists for the monument and to assess inventory completeness. There have been 784 species recorded at Montezuma Castle NM, of which 85 (11%) are non-native. In each taxon-specific chapter we highlight areas of resources that contributed to species richness or unique species for the monument. Of particular importance are Montezuma Well and Beaver and Wet Beaver creeks and the surrounding riparian vegetation, which are responsible for the monument having one of the highest numbers of bird species in the Sonoran Desert Network of park units. Beaver Creek is also home to populations of federally-listed fish species of concern. Other important resources include the cliffs along the creeks and around Montezuma Well (for cliff and cave roosting bats). Based on the review of past studies, we believe the inventory for most taxa is nearly complete, though some rare or elusive species will be added with additional survey effort. We recommend additional inventory, monitoring and research studies.

Monumental Masonry Buildings Pre-Assessment Method Based on Risk Assessment

Full Text Available Depending on the construction period, geometrical typology, construction and organization of the structure, element size and construction material of historic monumental structures; constructed with bricks, stones, adobe and mortar, are diverse and very complicated. Structural safety is guaranteed by the codes, guidelines, and specifications for recently constructed concrete and steel buildings, but there is no specific criterion for evaluating the historic monumental buildings. This study presents a scoring system method for classifying the risk level of the historic monumental structures based on visual information. This method is based on the acquisition of visual data of the building by using the developed building inspection form, storage of the acquired data on the web database and evaluation of the risk score of the inspected building automatically by the computer database system.

Vascular Plant and Vertebrate Inventory of Tuzigoot National Monument

2005-01-01

Executive Summary From 2002 to 2004, we surveyed for plants and vertebrates (amphibians, reptiles, birds, and mammals) at Tuzigoot National Monument (NM) and adjacent areas in Arizona. This was the first effort of its kind in the area and was part of a larger effort to inventory vascular plants and vertebrates in eight National Park Service units in Arizona and New Mexico. In addition to our own surveys, we also compiled a complete list of species that have been found by previous studies. We found 330 species, including 142 that had not previously been recorded at the monument (Table 1). We found 39 species of non-native plants, 11 non-native fishes, three non-native birds, and one non-native species each of amphibian and mammal. Based on our work and that of others, there have been 597 species of plants and vertebrates found at the monument. The bird community at the monument had the highest species richness of any national park unit in central and southern Arizona. We found all other taxa to have intermediate species richness compared to other park units in the region. This extraordinary species richness observed for birds, as well as for some other taxa, is due primarily to Tavasci Marsh and the Verde River, two critical sources of perennial water, which provide habitat for many regionally rare or uncommon species. The location of the monument at the northern edge of the Sonoran Desert and at the southern edge of the Mogollon Rim also plays an important role in determining the distribution and community composition of the plant and vertebrate communities. Based on our findings, we believe the high number of non-native species, especially fish and plants, should be of particular management concern. We detail other management challenges, most notably the rapid increase in housing and associated commercial development near the monument, which will continue to impact the plant and vertebrate communities. Based on our data and a review of past studies, we believe the

Classification and recognition of the heritage values of the monuments of Tlemcen

Full Text Available The first classification of historic monuments of Tlemcen dates from 1900 and the last from 2010. The 82 monuments date back to the Berber, Muslim and Roman eras. After the independence of Algeria, the French colonial heritage is not concerned by the rankings. They were removed from the list of monuments that was established by the French before 1962. The historic city of Tlemcen dates from the year 201 AD and features many old buildings. The latest ranking list does not reflect the architectural richness of this city. We then asked about the possibility of classifying the other historic buildings. From this questioning, we first identified all cultural goods which could be classified. Then we have evaluated these buildings following a grid of 20 heritage values. They are mentioned in the national and international legislation. It turns out that only 1.57 % of monuments of this city are classified.

2006-01-01

Executive Summary This report summarizes the results of the first comprehensive biological inventory of Gila Cliff Dwellings National Monument (NM) in western New Mexico. This project was part of a larger effort to inventory plants and vertebrates in eight National Park Service units in Arizona and New Mexico. Our surveys address many of the objectives that were set forth in the monument's natural resource management plan almost 20 years ago, but until this effort, those goals were never accomplished. From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at Gila Cliff Dwellings NM to document presence of species within the boundaries of the monument. For all taxonomic groups that we studied, we collected 'incidental' sightings on U.S. Forest Service lands adjacent to the monument, and in a few cases we did formal surveys on those lands. Because we used repeatable study designs and standardized field techniques, these inventories can serve as the first step in a biological monitoring program for Gila Cliff Dwellings NM and surrounding lands. We recorded 552 species at Gila Cliff Dwellings NM and the surrounding lands (Table 1). We found no non-native species of reptiles, birds, or mammals, one non-native amphibian (American bullfrog), and 33 non-native plants. Particularly on lands adjacent to the monument we found that the American bullfrog was very abundant, which is a cause for significant management concern. Species of non-native plants that are of management concern include red brome, bufflegrass, and cheatgrass. For a park unit of its size and geographic location, we found the plant and vertebrate communities to be fairly diverse; for each taxonomic group we found representative species from a wide range of taxonomic orders and/or families. The monument's geographic location, with influences from the Rocky Mountain, Chihuahuan Desert, and Madrean ecological provinces, plays an important role in determining

Daily and seasonal changes in temperature and humidity, wind, snow and rainfall, soluble salts carried by water, biological agents, pollutant gases and particulate matter are some of the agents in atmospheric environment that introduce weathering by physical, chemical and biological processes in the materials of the monuments such as natural building stones, bricks, mortars and plasters, mud brick etc. The weathering processes need to be well diagnosed by identification of main mechanisms of decay and major responsible agents, degree and depth of deterioration expressed with measurable parameters of physical, physicomechanical properties, and micro structural changes together with their distribution on the monument. Success of conservation treatments strongly depend on those diagnostic studies and compatibility of the treatments with the deteriorated and relatively sound parts of the historic materials. Current approach to materials conservation is to be able to make minimum intervention to historic material by targeting the conservation treatment to the deteriorated area for the purpose of controlling the deterioration factors and achieving compatible and durable conservation of historical material. In this presentation, two examples of diagnostic research and conservation treatments based on and guided by the diagnostic results are summarized concerning historic stone monuments exposed to atmospheric environment since more than two thousand years. The first example is on the marble walls of Temple of Augustus in Ankara exposed to polluted urban atmosphere. The second example is on the limestone statues of Nemrut Mount Monument in Adıyaman-Turkey, exposed to rural atmosphere with harsh climatic conditions. Finally, a brief discussion on current research issues related to historic materials conservation in

Monumentality and public space in Lourenço Marques in the 1930 and 1940

Full Text Available Lourenço Marques, actual Maputo (Mozambique, is subjected to a series of aesthetic interventions in its public space during the 1930s e 1940s. These seek to “monumentalize” and “portugalize” the city, responding to its recently acquired status as capital of the Colony. Two monuments appear as especially important and exemplary: the Padrão de Guerra, a lately built First War memorial (1935, and the monument to the hero of the “pacification campaigns” of the 1890s, Mouzinho de Albuquerque (1940. Around these monuments, a large number of commemorative and celebrative practices are developed. Such practices posit the monument as a “national allegory” and reproduce, in the context of a modern city, auratic and cult values. As such, they add an important dimension to the monument’s role in the authoritarian reformulation of the city’s public space as an “imperial” space, as well as in the putative hegemonization of the representations of the community imagined as a “Nation”. They allow, therefore, to approach the political-ideological use and utility of the monument within the organization of public space.

The elk herd that frequents Fossil Butte National Monument, a subset of the West Green River elk population, provides visitors with seasonal opportunities to view an iconic species of the western United States. Throughout the year, these elk range across a variety of private, State, and Federal lands within close proximity to the Monument. These lands are managed differently for various uses which can create challenging wildlife-management issues and influence the herd’s seasonal movements and distribution. Research lead by the USGS investigates some of the factors associated with these seasonal changes.

COMPUTER ASSISTED LOOM IN THE REVIVAL OF CONTEMPORARY MONUMENTAL TAPESTRY

Directory of Open Access Journals (Sweden)

PINTILIE Anca-Aurelia

2015-05-01

Full Text Available The art of tapestry has its basics back in time, probably in the decorations of tent, the house of the nomad. Tapestry in its beginnings is the first wall of the nomad’s home and the decorative wall and canopy in the ancient Greek houses as architect Gottfried Semper stated in the nineteen century. The architectural approach is not unusual even in the next centuries. Tapestry becomes popular as a form of monumental art during the Middle Ages when it is used as decorative architectural element, coating the walls of medieval castles. During the next centuries dominated by decadent styles of baroque, rococo, the tapestry will lose its monumental spirit and architectural quality but at the middle of the XXth century a new approach will sustain the revival of the tapestry as monumental art. Later, in the XXIst century, renowned multimedia artists will approach this medium and will use computer assisted looms in ambitious tapestry projects. This technique will allow them to realize complex and exquisite tapestries, sustaining in this way the revival of the tapestry in the contemporary art world. The paper presents the importance of the architectural side of tapestry and the great achievement that computer assisted loom represents for this form of art. The research activity is willing to inform Romanian textile designers about the possibilities to create tapestries on computer assisted looms. The research was made during the initial stage of a doctoral thesis consisting in a documentary study on monumental aspects of contemporary tapestry.

A Parallel Algorithm for the Counting of Ellipses Present in Conglomerates Using GPU

Directory of Open Access Journals (Sweden)

Reyes Yam-Uicab

2018-01-01

Full Text Available Detecting and counting elliptical objects are an interesting problem in digital image processing. There are real-world applications of this problem in various disciplines. Solving this problem is harder when there is occlusion among the elliptical objects, since in general these objects are considered as part of the bigger object (conglomerate. The solution to this problem focusses on the detection and segmentation of the precise number of occluded elliptical objects, while omitting all noninteresting objects. There are a variety of computational approximations that focus on this problem; however, such approximations are not accurate when there is occlusion. This paper presents an algorithm designed to solve this problem, specifically, to detect, segment, and count elliptical objects of a specific size when these are in occlusion with other objects within the conglomerate. Our algorithm deals with a time-consuming combinatorial process. To optimize the execution time of our algorithm, we implemented a parallel GPU version with CUDA-C, which experimentally improved the detection of occluded objects, as well as lowering processing times compared to the sequential version of the method. Comparative test results with another method featured in literature showed improved detection of objects in occlusion when using the proposed parallel method.

National uranium resource evaluation, Las Vegas Quadrangle, Nevada, Arizona, and California

The Las Vegas 1 0 x 2 0 quadrangle, Nevada, Arizona, and California, contains rocks and structures from Precambrian through Holocene in age. It lies within the Basin and Range physiographic province adjacent to the westernmost portion of the Colorado Plateau. Miocene nonmarine sedimentary rocks of the Horse Spring Formation contain in excess of 100 tons U 3 O 8 in deposits at a grade of 0.01% or greater, and therefore meet National Uranium Resource Evaluation base criteria for uranium favorability. One favorable area lies in the South Virgin Mountains at the type locality of the Horse Spring Formation, although the favorable environment extends into the unevaluated Lake Mead National Recreation Area and Desert National Wildlife Range. Environments within the Las Vegas Quadrangle considered unfavorable for uranium include the Shinarump Conglomerate member of the Triassic Chinle Formation, Mesozoic sediments of the Glen Canyon Group, Precambrian pegmatites, Pliocene and Quaternary calcrete, Laramide thrust faults, and a late Precambrian unconformity

Thoughts about uranium-bearing quartz-pebble conglomerates: a summary of ideas presented at the workshop

International Nuclear Information System (INIS)

Skinner, B.J.

1981-01-01

A summation of papers given at the Workshop on the Genesis of Uranium- and Gold-Bearing Precambrian Quartz-Pebble Conglomerates held at Golden, Colorado, on October 13-15, 1975, is presented. Seven pertinent topics, chosen by the author, are compiled from the several papers and are critically discussed. The time of formation of these deposits is between 3- and 2-billion years ago. The uraniferous conglomerates appear to be of fluvial origin and the known uranium reserves are plotted along an idealized fluviatile system. The source areas for the placers are related to 3 billion year old granites, greenstones and metamorphic rocks of the cratons - these most probably were located paleogeographically in a polar region. The role of diagenesis in the formation of uranium ores is discussed with respect to oxygen content of Precambrian atmospheres and of subsurface waters. The effect of subsequent metamorphism and recrystallization upon indigenous pyrites and kerogen is related. Finally characteristics of known uranium deposits are correlated to suggest a strategy to be employed while prospecting for undiscovered uranium ores. (DT)

The Places of Memory in a Square of Monuments: Conceptions of Past, Freedom and History at Szabadság Tér

Directory of Open Access Journals (Sweden)

Erik Thorstensen

2012-01-01

Full Text Available In this paper I try to approach contemporary Hungarian political culture through an analysis of the history of changing monuments at Szabadság Tér in Budapest. The paper has as its point of origin a protest/irredentist monument facing the present Soviet liberation monument. In order to understand this irredentist monument, I look into the meaning of the earlier irredentist monuments under Horthy and try to see what monuments were torn down under Communism and which ones remained. I further argue that changes in the other monuments also affect the meaning of the others. From this background I enter into a brief interpretation of changes in memory culture in relation to changes in political culture. The conclusions point toward the fact that Hungary is actively pursuing a cleansing of its past in public spaces, and that this process is reflected in an increased acceptance of political authoritarianism.

Neolithic Ground Axe-heads and Monuments in Wessex

Directory of Open Access Journals (Sweden)

David Field

2009-09-01

Full Text Available While central southern England is well known for its extant Neolithic monuments and for the fine artefacts recovered from some of its Bronze Age barrows, Neolithic artefacts from the region have received relatively little attention. This might be considered surprising, as the area not only witnessed some of the earliest investigations into the source of materials, notably the Stonehenge bluestones, but it also harbours some of the earliest dated ground axes in the country. This article examines the occurrence and distribution of ground axes found in Wessex when compared to other artefact types, but, more importantly, comparison with the location of extant monuments allows a rather different view of Wessex to emerge. The article will consider the influence of local resources, of flint mines such as those at Durrington, Easton Down and Porton Down in Wiltshire, and the extent and processes by which axes of non-local materials may have been introduced and dispersed across the landscape.

Some aspects of the genesis of heavy mineral assemblages in Lower Proterozoic uranium-gold conglomerates

International Nuclear Information System (INIS)

Clemmey, H.

1982-01-01

Some genetic models for Lower Proterozoic gold- and uranium-bearing pyritic conglomerates favour a modified placer origin in which low levels of atmospheric oxygen are used to account for the survival of uraninite and pyrite. There are many difficulties with such models. New evidence concerning the genesis of the deposits is derived from a clast of ferric iron clay thought to represent a precursor sediment of the Witwatersrand Basin. Reworking of such clays and transport of a magnetite and ferric clay assemblage with subsequent sulphidation, could account for the porous pyrites, the absence of magnetite and the lack of hydraulic equivalence of the mineral grains in the conglomerates. The presence of oxygen, as indicated by the ferric iron clasts, would account for the evidence of mobility of uranium and of gold and would enhance their extraction from source rocks; particularly the release of gold from a precursor auriferous iron formation source. It is suggested that some aspects of the genesis of uranium deposits of the Witwatersrand and Elliott Lake may be similar to those of the Phanerozoic 'Roll Front' ores involving interaction between oxidizing uraniferous groundwaters and previously sulphidized and reduzate facies sediments.

Astronomy, Illumination and Heritage: the Arles-Fontvieille megalithic monuments and their implications for archaeoastronomy and world heritage

Science.gov (United States)

Sterling Saletta, Morgan

2015-08-01

Recent archaeoastronomical research at the Arles-Fontvieille monuments has important implications for establishing potential Outstanding Universal Value of megalithic monuments and establishing the credibility of archaeoastronomical sites. My discovery of seasonal light and shadow hierophanies within the Arles-Fontvieille monuments has interpretive and heritage value implications not only for these sites but for late prehistoric European monuments more generally.While horizon astronomy was very likely used for time-reckoning in the Neolithic, I argue the ‘seasonal illumination hypothesis’ is more appropriate than the ‘celestial targeting paradigm’ not only for the interpretation of the role of astronomy and cosmological symbolism in the construction of the Arles-Fontvieille monuments but also for late prehistoric European tombs with chambers and passages more generally.Multiple lines of evidence suggest a cosmologically symbolic link between houses of the living and houses of the dead in late prehistoric Europe. I will suggest that this practice originated not only in symbolic aspects of domestic dwellings, but also in functional solar orientation.If seasonal illumination was a major impetus for the orientation signatures of late prehistoric European monuments, how best to establish this? Time-lapse photography or video, while not unproblematic, is a powerful method of establishing the credibility of archaeoastronomical sites- one which has been used to great effect at monuments such as Newgrange and Stonehenge. In the past, this method was limited by the cost of equipment and the time needed to visit sites and at specific periods of time. Both of these limitations have been significantly lessened in recent years. Digital cameras have become ubiquitous. More importantly, examples of “crowd-sourcing” research problems in science provide a strategy for field documentation of sites whose level of preservation is sufficient to reveal seasonal illumination

Gypsum-induced decay in granite monuments in Northwestern Spain

Directory of Open Access Journals (Sweden)

Silva Hermo, B.

2010-03-01

Full Text Available One of the most common forms of decay in granite monuments is the detachment of the superficial layer of the stone (plaques, plaquettes and scales. Previous studies of granite monuments in the northwest Iberian Peninsula revealed a direct relation between this type of weathering and the presence of calcium sulphate, and a mechanism whereby the salt causes this type of decay was suggested. In the present study, various hypotheses as regards the origin of the gypsum found in granite monuments are proposed. The study involved analysis of the contents of ions soluble in water, the results of X-ray diffraction analyses and the ratios of CaO/SO₃ in samples of stone, mortar and deposits collected from different monuments. It was concluded that in most cases the gypsum originated from old paintworks or/and from the joint mortars, although inputs from other sources cannot be discounted, as discussed

Una de las formas de deterioro más frecuente en los monumentos graníticos es la separación de la capa superficial de la piedra (placas, plaquetas y escamas. En trabajos anteriores centrados en monumentos del noroeste de la Península Ibérica, se constató la relación directa entre esta forma de alteración y la presencia de sulfato de calcio y se propuso el mecanismo a través del cual esta sal provoca este tipo de deterioro. En este trabajo se plantean varias hipótesis acerca del origen del yeso encontrado en monumentos graníticos. Para ello se comparan los contenidos de iones solubilizados en agua, los resultados de difracción de rayos X y las relaciones OCa/SO₃ de muestras de piedra, morteros y depósitos recogidas en diferentes monumentos. Se llega a la conclusión de que en la mayor parte de los casos el yeso procede de antiguas pinturas o de revestimientos superficiales y de los morteros de juntas entre sillares, pero no se puede descartar la contribución de otros aportes, los cuales se discuten también en este artículo.

Vascular Plant and Vertebrate Inventory of Tonto National Monument

Albrecht, Eric W.; Powell, Brian F.; Halvorson, William L.; Schmidt, Cecilia A.

2007-01-01

This report summarizes the results of the first biological inventory of plants and vertebrates at Tonto National Monument (NM). From 2001 to 2003, we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at Tonto NM to record species presence. We focused most of our efforts along the Cave Springs riparian area, but surveyed other areas as well. We recorded 149 species in the riparian area, and 369 species overall in the monument, including 65 plant species and four bird species that were previously unrecorded for the monument. We recorded 78 plant species in the riparian area that previous studies had not indicated were present there. Several species of each taxonomic group were found only in the riparian area, suggesting that because of their concentration in this small area these populations are vulnerable to disturbance and may be of management concern. Four of the bird species that we recorded (Bell's vireo, yellow warbler, summer tanager, and Abert's towhee) have been identified as riparian 'obligate' species by other sources. Bird species that are obligated to riparian areas are targets of conservation concern due to widespread degradation of riparian areas in the desert southwest over the last century. The flora and fauna of the riparian area would benefit from continued limited public access. The dependence of the riparian area on the spring and surface flow suggests monitoring of this resource per se would benefit management of the riparian area's flora and fauna as well. The monument would benefit from incorporating monitoring protocols developed by the Sonoran Desert Network Inventory and Monitoring program rather than initiating a separate program for the riparian area. Park managers can encourage the Inventory and Monitoring program to address the unique monitoring challenges presented by small spatial areas such as this riparian area, and can request specific monitoring recommendations. We suggest that repeat

Main Features of a 3d GIS for a Monumental Complex with AN Historical-Cultural Relevance

Science.gov (United States)

Scianna, A.; La Guardia, M.

2017-05-01

The last achievements of technologies in geomatics especially in survey and restitution of 3D models (UAV/drones and laser scanner technologies) generated new procedures and higher standards of quality in representation of archaeological sites. Together with Geomatics, the recent development of Information and Communication Technologies (ICT) strongly contribute to document and the Cultural Heritage (CH). The representation and documentation of CH using these new technologies has became necessary in order to satisfy different needs: - for restorers in order to acquire a deep knowledge of the cultural good and to define possible strategies of restoration; - for the conservation of information, allowing to preserve the 3D geometry of the monumental complex with the integration of descriptions about architectural elements; - for touristic aims, giving the opportunity of sharing CH information on web, allowing users to visit and explore, in a virtual way, monumental complexes, acquiring information details about architectural elements or the history of monumental complex. Looking through these new scenarios, the development of a 3D Geographic Information System (GIS) applied to a cultural good could be, today, an added value of fundamental importance for full description and data management of monumental complexes. In this work, the main features necessary for the correct construction of a 3D GIS of a monumental complex will be analyzed, with a particular focus on the possibilities for creating a standardized procedure to follow.

Technical Limitations in Merging Secular and Sacred Functions in Monumental Churches

Science.gov (United States)

Piatkowska, Ksenia

2017-10-01

The abandonment of churches and their adaptation for secular purposes is a current subject in Europe and worldwide. Most cases involve objects that were desacralized and then rebuilt as a whole object for alternative functions. Thus far, the merging of secular and sacred functions in one monumental Catholic church has not raised any issues. The paper describes the case of St. Catherine’s Church in Gdansk, Poland, where sacred function exists parallel to the new secular function being implemented. The study is based on the authentic, professional experience of the author. It describes the technical limitations arising from the need to ensure destinies for the optimal conditions of both sacred and secular function, while avoiding undesirable interference between them. The author further identifies architectural solutions most relevant to current requirements for protection of sacred zones in the church, for preservation of the monument, and for optimal function of a modern science museum. Significant design issues include: the inviolability of the sacred zone, preservation of the historical value of the monument, proper operation of new secular zones in compliance with contemporary standards of safety, performance of the assumed mission and profitability. The research indicates specific areas where the highest probability of collision exists between the sacred and profane and where technical problems are likely to occur.

In the field experiment, the block of Ramesses II (19th Dynasty, ca. 1270 B.C.), the Wooden Coffin of Neb-sny (18th Dynasty, ca. 1400 B.C.), the Funerary Stele of Amenemhat (11th Dynasty, ca. 2000 B.C.), and the painted walls of the Tomb of Userhat (18th Dynasty, ca. 1400 B.C.) were investigated. From white and blue colored parts, huntite and Egyptian blue were found, respectively, which are a very rare mineral and an artificial pigment prepared only in ancient Egypt, respectively. (author)

Genesis of uranium-gold pyritic conglomerates

International Nuclear Information System (INIS)

Myers, W.B.

1981-01-01

The ancient pyritic ore conglomerates have a common origin best exemplified by the Witwatersrand deposits. All contain detrital pyrite and uraninite, which are unstable in modern oxygenated environments and were deposited in a reducing atmosphere. The Rand reefs are not similar to modern gold placers. Placers result from the near incapacity of streams and currents to transport coarse gold. Placers as rich as Rand reef occur only in narrow paystreaks within 15 kilometers of a coarse-gold source. The board dispersion of gold in the reefs is due to solution transport of metal complexed as aurous sulfide, leached anoxygenically from crustal rocks, probably from sea-floor basalt, and precipitated by a slow reaction driven by the radioactive decay of detrital uraninite. Radiolysis of water on shallow marine unconformities resulted in diffusion of hydrogen to the atmosphere and a slight excess of hydroxyl free radical in the reef environment. The mild oxidizing tendency slowly dissolved uranium, precipitated gold, and oxygenated thucholite. These actions define a maturing process. A uraninite placer accumulating on an unconformity becomes progressively converted to a gold reef with little residual uraninite. The most mature reefs tend to grade toward the thucholite-seam type, very thin but exceedingly rich in gold. A combination of chemical attack and physical reworking accounts for the general thinness of mature reefs. Pyrite, like uraninite, decreases in abundance with increasing maturity; buffering by pyrite moderated the oxidative depletion of uranium. Where pyrite was scanty or absent, uraninite was completely dissolved by the effects of radiolysis and no ore formed

Bacterial bio-mediated calcite precipitation for monumental stones conservation: methods of evaluation.

Science.gov (United States)

Tiano, P; Biagiotti, L; Mastromei, G

1999-05-01

The weathering of monumental stones is a complex process inserted in the more general 'matter transformation cycle' operated by physical, chemical and biological factors. The consequence of these combined actions is a loss of cohesion with dwindling and scaling of stone material and the induction of a progressive mineral matrix dissolution. In the case of calcareous stones, calcite leaching increases the material porosity and decreases its mechanical features with a general weakening of the superficial structural strength. Attempts to stop, or at least to slow down, deterioration of monumental stones has been made by conservative treatments with both inorganic or organic products. More recent studies show a new approach to hinder these phenomena by inducing a bio-mediated precipitation of calcite directly inside the stone porosity. This can be achieved either through the application of organic matrix macromolecules extracted from sea shells or of living bacteria. The effectiveness of the treatment using calcinogenic bacteria has been evaluated with laboratory tests specifically developed to evaluate the parameters such as : porosity, superficial strength and chromatic changes, influenced by the treatment itself. The results obtained seem to indicate that this type of treatment might not be suitable for monumental stone conservation.

Monuments devoted to artists in public spaces around museums: A nineteenth-century strategy to enhance the urban space of art districts

Directory of Open Access Journals (Sweden)

Lorente, J. Pedro

2014-12-01

Full Text Available Monuments to kings or military heroes have always been positioned in main squares and avenues, whilst those erected to famous cultural figures were a novelty introduced in the Enlightenment and Romanticism, placing busts or sitting monuments to writers or musicians in secluded gardens and in the surroundings of libraries, theatres, etc. During the nineteenth century, monuments to artists became also a common feature in many cities, where a most likely emplacement for them was in front of some art museum. In a way, they were a complement to the ornaments of such building, usually decorated with portraits and inscriptions glorifying great artists; but the monument to Murillo erected in 1863 by public subscription in Seville's Plaza del Museo was also an urban milestone, catching the attention of promenading public passing along a lateral street. Later, the monuments erected in the piazzas around the Prado Museum in Madrid, or in gardens outside the Louvre, became a popular prototype, emulated in many other cities up to the early 20th century. Their role as interfaces between public spaces and museum sites would thereafter be taken over by other kinds of artistic landmarks: not monuments to artists, but monumental artworks, often owned by the museum itself, thus bringing part of its collection outside, as a welcome starter to prospective cultural consumers.

Monuments in the Structure of an Urban Environment: The Source of Social Memory and the Marker of the Urban Space

The major research objective was to analyze the role of monuments in the formation of local residents’ and guests’ representations about the city, its history and traditions. The authors consider the system of monuments’ location in the urban space as a way of its social construction, as the system of influence on citizens’ aesthetic feelings, as the formation of their attitudes towards maintaining of continuity in the activities of different generations for the improvement of the territory of their permanent residence. Methodology. An urban monument is considered in two ways: as a transfer of historical memory and as a social memory transfer, which includes the experience of previous generations. One of the main provisions of the study is the idea that monuments can lose their former social value, transforming into “simple” objects of a public place. The study was conducted in the city of Yekaterinburg, one of the largest, cultural, scientific and industrial Russian megalopolises in 2015. The primary data was collected using standardized interviews. Four hundred and twenty respondents at the age of and above 18 were questioned on the basis of quota sampling. Interviews with respondents were conducted in order to identify key problems involved and reasons for shaping respondents’ representations of monuments in the urban environment typical for the population of Russian megalopolises. The standardized interview guide included 15 questions. Findings and discussion. Our investigation has revealed that different monuments fulfil various functions in an urban environment (ideological, aesthetic, transferring, valuable, etc.). The study has unequivocally confirmed that objects in the urban space have a different emotional colour background: people paint them in accordance with the feelings that arise in their perception. Hence, some monuments effectively fulfil the functions of social memory transfer: they are remembered, they tell us about the events to

Acoustical features of two Mayan monuments at Chichen Itza: Accident or design?

Science.gov (United States)

Lubman, David

2002-11-01

Chichen Itza dominated the early postclassic Maya world, ca. 900-1200 C.E. Two of its colossal monuments, the Great Ball Court and the temple of Kukulkan, reflect the sophisticated, hybrid culture of a Mexicanized Maya civilization. The architecture seems intended for ceremony and ritual drama. Deducing ritual practices will advance the understanding of a lost civilization, but what took place there is largely unknown. Perhaps acoustical science can add value. Unexpected and unusual acoustical features can be interpreted as intriguing clues or irrelevant accidents. Acoustical advocates believe that, when combined with an understanding of the Maya worldview, acoustical features can provide unique insights into how the Maya designed and used theater spaces. At Chichen Itza's monuments, sound reinforcement features improve rulers and priests ability to address large crowds, and Ball Court whispering galleries permit speech communication over unexpectedly large distances. Handclaps at Kukulkan stimulate chirps that mimic a revered bird (''Kukul''), thus reinforcing cultic beliefs. A ball striking playing field wall stimulates flutter echoes at the Great Ball Court; their strength and duration arguably had dramatic, mythic, and practical significance. Interpretations of the possible mythic, magic, and political significance of sound phenomena at these Maya monuments strongly suggests intentional design.

THE UNDERSTANDING OF THE TOURISTIC VALUE OF PORTUGUESE OVERSEAS MONUMENTS: THE CASE OF ANGOLA (1959-1974

Vera Mariz

2016-06-01

Full Text Available The present study aimed to evaluate the understanding of the touristic value of Portuguese overseas monuments during Estado Novo, having as case-study the then colony of Angola between 1959 and 1974, years marked by the creation of the Information and Tourism Centre and the fall of the regime. Thus, considering the reality of the metropolis, we aimed to identify and analyse the evolution of tourism in this territory, as well the understanding and use of historic monuments by a nationalist regime as points of touristic interest and legitimisers of the national colonialism. We argue that during two different but totally complementary moments devoted to the relation between tourism and historic monuments of Angola, there was a real understanding of their touristic value. Besides that we claim that the believers of the touristic value of those monuments were very often advocates of the preservation or restoration of their pristine characteristics, an idea that we can affiliate to the thought of António Ferro to whom the success of tourism was extremely dependent on preserving and emphasizing the picturesque and idiosyncratic characteristics of those tourist destinations. To achieve our goals we have identified and analysed some tourism-related periodicals, thematic studies and legislation.

Cultural monuments from exceptional importance in Serbia as anthropogenic tourist values

Full Text Available Cultural monuments mark historical past. They are included in anthropogenic tourist values. They present rare copies of creativity and they have exceptional artistic and esthetic values. The most numerous group are sacral objects. The largest attention deserve objects assigned in World cultural inheritance - monastery Studenica and monastery Sopoćani with old town Ras. It is necessary to build caterer capacities, parking lots and sanitary devices in encirclement. Manifestations and presentations on domestic and foreign market contribute to cultural affirmation. Tourist valorization is impeded with that there are no evidence about number of visitors. In separating priorities we must consider uniqueness, rarity and fame. That’s the reason why Čele kula has tourist importance. Cultural monuments increase stay and serve as complementary tourist values. That’s why is necessary synthesis access in their learn and tourist presentation.

Ionizing radiation can be used for conservation of monuments and old art objects. The irradiation of wooden and cellulose objects for disinfestation has been described. The irradiation conditions and lethal doses in respect to different species have been discussed. The different technique is the radiation consolidation of historical objects made of various materials. The method consists in radiation polymerization. The object undergoing conservation is saturated with monomer prior irradiation. The radiation polymerization results in consolidation of the object pieces and reinforcement of its material. 3 figs

2015-01-01

Full Text Available One of the most prospective directions in preservation  and increase of service live of  road pavements is a construction of  automobile roads with cement concrete surface. Modern tendencies for provision of road construction quality presuppose a necessity to control processes of solidification and subsequent destruction of the material while forming and using cement concrete conglomerate being considered as a basic element of the road surface.  Multiyear practical experience of  automobile road operation using cement concrete pavements reveals an importance for monitoring  such processes as formation and destruction of cement concrete materials. An impedance spectroscopy method has been tried out and proposed as a tool for solution of the given problem.Experimental samples of cement concrete have been prepared for execution of tests, graded silica sand and granite chippings with particle size from 0.63 to 2.5 mm have been used as a fine aggregate in the samples. Dependencies of resistance (impedance on AC-current frequency  have been studied for samples of various nature and granulometric composition. The Gamry  G300 potentiostat has been used for measurement of complex impedance value. A spectrum analysis and calculation of equivalent circuit parameters calculation have been carried out while using EIS Spectrum Analyzer program.Comparison of impedance spectra for the prepared cement concrete samples have made it possible to reveal tendencies in changing spectrum parameters during solidification and subsequent contact with moisture in respect of every type of the sample. An equivalent electrical circuit has been developed that  characterizes physical and chemical processes which are accompanied by charge transfer in cement concrete conglomerate. The paper demonstrates a possibility to use an impedance spectroscopy for solution of a number of actual problems in the field of cement concrete technology problems. Particularly, the problems

ENGLISH: Recent analysis of the epigraphy on Monument 1 from Xkombec indicates that the monument can be dated to A.D. 866, not to the mid-8th century as was previously argued. This new date marks Monument 1 as contemporary to the monuments at Xcalumkin and other neighboring Puuc sites. According to the text contained on Monument 1, political organization of Xkombec was similar to that of other Puuc centers.

The pagan world was conquered by Christianity, and therefore had the remains of one reason only be based on the exaltation of the glory of Christ and his Church.

Attacks on South African monuments: Mediating heritage in post-conflict society

2018-05-01

Full Text Available The controversy surrounding the notion of national heritage and what constitutes a proper heritage in post-apartheid South Africa intersects with issues of identity and identity formation in a post-conflict society. That it impinges powerfully on social cohesion has been thrust into the spotlight in view of recent protest action related to colonial and apartheid era monuments. We have made the point elsewhere that conflict resolution in South Africa through negotiations, the National Peace Accord and the Truth and Reconciliation Commission has, at best, been partial, that it has not always been taken sufficiently seriously to engage with the fault-lines of protracted social conflict in the country. This article has employed a qualitative methodology because it is both descriptive and explorative in nature. The main aim of this article is to provide a critique on how issues of intersectionality (race, class and gender coincide with the attacks of the monuments by university students in South Africa. This article utilises two theoretical frameworks, namely, classical Marxism and Black Consciousness, simply because both the psychological and class analysis were invoked by the student bodies to diagnose and prognose the challenges of black South Africans within the context of higher education in South Africa. The central thesis of this article is that the attacks on monuments in South African universities were instigated by a group of young people who claim to be revolutionary in thinking and are calling for transformation, free education, dismantling gender oppression and doing away with institutionalisation of racism.

Full Text Available When an urban development is planned the cartography of this territory is necessary, in the same way before starting a project to rehabilitate a monument the graphic information about it has to be available. At present, different techniques are available which allow to obtain three-dimensional models with a different accuracy level and runtimes.This paper shows the work carried out to obtain the graphic information and three-dimensional models that are necessary for the rehabilitation project of the tomb of Queen Elisenda in the Monastery of Pedralbes, Barcelona (Spain. This monument has the peculiarity of being symmetrical about the wall separating monastery church and the cloister. To do this, different techniques have been used that allow us to obtain an accurate model and as complete as possible, for the analysis of the construction process of the monument. In order to achieve the complete architectural survey the integration of laser scanning and photogrammetric data, and CAD models has been necessary. Due to the detail of the sculptures and the Queen’s sarcophagus two sensors, with different resolution, range and accuracy, have been used to obtain the laser scanning data. Stereo pairs have been taken to obtain the 3D model of these elements to complete the model and obtain an ortophotography.In this way, a comparative analysis of both techniques has been carried out, in order to decide which one is the suitable for certain application. This investigation has been restricted to the tomb, in the two symmetrical parts of the monument.

Full Text Available The cultural patrimony preserves the memory and identity of the Banat’s rural area, defining the personality specific to each locality depending on the colonizing ethnic group after the liberation from the Turkish yoke. Steadily degrading, this baroque sculptural patrimony must be saved and integrated into a tourist circuit through the development of a managerial strategy and the implementation of a total quality management that cover the widest area possible of issues related to the intact preservation of monuments and to their conservation. The valorisation of monumental baroque sculpture in the rural area must be done together with the development of a managerial strategy of sustainable development thus contributing to the making up of an emblematic image specific to the Banat village and to the inclusion into regional, national, and international tourist circuits through such modern forms of tourism as cultural tourism, rural tourism, heritage tourism, interethnic tourism, religious tourism, and business tourism.

Creating/Curating Cultural Capital: Monuments and Museums for Post-Apartheid South Africa

Directory of Open Access Journals (Sweden)

Elizabeth Rankin

2013-03-01

Full Text Available Since the first democratic elections in 1994, South Africa has faced the challenge of creating new cultural capital to replace old racist paradigms, and monuments and museums have been deployed as part of this agenda of transformation. Monuments have been inscribed with new meanings, and acquisition and collecting policies have changed at existing museums to embrace a wider definition of culture. In addition, a series of new museums, often with a memorial purpose, has provided opportunities to acknowledge previously marginalized histories, and honor those who opposed apartheid, many of whom died in the Struggle. Lacking extensive collections, these museums have relied on innovative concepts, not only the use of audio-visual materials, but also the metaphoric deployment of sites and the architecture itself, to create affective audience experiences and recount South Africa’s tragic history under apartheid.

The DOE's goal is to implement a cost-effective site strategy that complies with the US Environmental Protection Agency (EPA) ground water standards and protects human health and the environment. The compliance strategy that emerges in the final version of the SOWP will be evaluated in the site-specific environmental assessment to determine potential environmental impacts and provide stakeholders a forum for review and comment. When the compliance strategy is acceptable, it will be detailed in a remedial action plan that will be subject to review by the state and/or tribe and concurrence by the US Nuclear Regulatory Commission (NRC). Information for the preparation of this SOWP indicates active remediation is the most likely compliance strategy for the Monument Valley site. Additional data are needed to determine the most effective remediation technology

Conservation and Management of Archaeological Monuments and Sites in Greece and Turkey: A Value-Based Approach to Anastylosis

Full Text Available Heritage management and monument conservation play a significant role in the preservation of archaeological heritage. Anastylosis, a process with a long history in the Mediterranean region, is discussed with relevance to current debates concentrating on concepts of value-based approaches. Examination of the diverse values that may be attributed to monuments provides an insight into the evolution of ideas in heritage management, conservation and restoration practices. In the current theoretical framework the concept of values, as attributed by all stakeholders, and its application when preserving archaeological heritage, are constantly debated. The participation of stakeholders in the process of value identification is considered fundamental by heritage management experts. This paper presents the findings of a survey conducted to collect the opinions of anastylosis and restoration professionals, with reference to case studies on a number of monuments subjected to anastylosis in Greece and Turkey, highlighting the importance of assessing values in order to establish the appropriate type and extent of intervention. The paper concludes that a value-based approach to decision-making and planning for anastylosis, or any other form of architectural conservation, is crucial for preserving monuments in a way that satisfies those who want to experience and benefit from heritage.

The presence and deteriorating action of micro-organisms on monuments and stone works of art have received considerable attention in the last few years. Knowledge of the microbial populations living on stone materials is the starting point for successful conservation treatment and control. This paper reviews the literature on cyanobacteria and chlorophyta that cause deterioration of stone cultural heritage (outdoor monuments and stone works of art) in European countries of the Mediterranean Basin. Some 45 case studies from 32 scientific papers published between 1976 and 2009 were analysed. Six lithotypes were considered: marble, limestone, travertine, dolomite, sandstone and granite. A wide range of stone monuments in the Mediterranean Basin support considerable colonization of cyanobacteria and chlorophyta, showing notable biodiversity. About 172 taxa have been described by different authors, including 37 genera of cyanobacteria and 48 genera of chlorophyta. The most widespread and commonly reported taxa on the stone cultural heritage in the Mediterranean Basin are, among cyanobacteria, Gloeocapsa, Phormidium and Chroococcus and, among chlorophyta, Chlorella, Stichococcus and Chlorococcum. The results suggest that cyanobacteria and chlorophyta colonize a wide variety of substrata and that this is related primarily to the physical characteristics of the stone surface, microclimate and environmental conditions and secondarily to the lithotype.

Facade renovation - replacement and restoration of the panels in a monument protected object

Science.gov (United States)

Novotný, Michal

2017-12-01

The article deals with problems of reconstruction of the facade and the associated problem of replacement or repair of the panels. In conventional buildings it is a smooth operation, but it is problematic in monument-protected objects. In the case of a common building, it is possible to choose any modern panels and simply replace them, but for historical objects we have to follow the claims and the rules of monument protection. In practice, it usually means the impossibility of use of modern panels, but at least a combination of old and modern technologies. Another possible solution to the problem is renovation, or repairs to the original state of the existing panels, of course with respect to the functionality of such panels. The implementation of such repairs must always be based on the technical and historical survey of the condition of the object and the repairs must be professionally designed. Subsequently, corrections are made, during which it is necessary to pay particular attention to observance of the technological procedures, rules and instructions particularly in terms of monument protection. However, the functionality of the works or elements made with regard to the quality of the environment within the building is not negligible. A common problem is the lack of control of technical requirements and functional requirements. Underestimation of the problems then leads to difficult repairs. The article points to the mistakes and problems of one such construction project on a historically protected chateau building.

Time–frequency analysis of GPR data to investigate the damage of monumental buildings

International Nuclear Information System (INIS)

Leucci, Giovanni; Persico, Raffaele; Masini, Nicola

2012-01-01

The presence of particular microclimatic conditions inside monumental buildings is responsible for bio-deterioration processes. In many cases, efflorescence and moulds are visible on the facades of several monuments of historical importance. In many other cases, the effects of decay processes are not visible, thus making difficult the diagnosis and the consequent setup of effective rehabilitation and preservation interventions, especially in the presence of a complex geometry and/or a large variability of construction materials. In such cases, a valuable contribution could be provided by geophysical methods (such as electrical resistivity, electromagnetic conductivity, ground-penetrating radar (GPR), etc), which have been proved to be successful tools for sub-surface investigation and characterization of historical buildings. In old monumental buildings, the masonry structures frequently exhibit cracks, voids, detachments and high moisture contrasts that can give rise to reflection events in radar signals. However, the complexity of the geometry and the structural heterogeneity that characterize these old structures often make the GPR results difficult to analyse and interpret. In particular, the spatial variation in GPR signal attenuation can provide important information about the electrical properties of the investigated materials that, in turn, can be used to assess the physical parameters associated with damage. In this paper, we propose an approach that analyses the data in the form of ‘frequency maps’ to evidence absorption losses probably linked to higher moisture content. Two real case histories back up the proposed method. (paper)

2017-08-01

Full Text Available The unwanted changes in valuable historic calcareous stone monuments due to exposure to many physical and chemical effects may lead to its deterioration. The growing interest in the field of conservation of stone monuments encourages the development of consolidation and water-repellent materials. The aim of this study is to evaluate the effectiveness of CaCO3 nanoparticles as a consolidation and protection material for calcareous stone monuments, when those nanoparticles used are dispersed in acrylic copolymer; polyethylmethacrylate (EMA/methylacrylate (MA (70/30, respectively. Samples were subjected to artificial aging by relative humidity/temperature to show the optimum conditions of durability and the effectiveness of the nano-mixture in improving the physical and mechanical properties of the stone material. The synthesis process of CaCO3 nanoparticles/polymer nanocomposite has been prepared by in situ emulsion polymerization system. The prepared nanocomposites with 0.15 g CaCO3 nanoparticles showed obvious transparency features and represent nanocomposites coating technology with hydrophobic, consolidating and good protection properties. Some tests were performed in order to estimate the superficial consolidating and protective effect of the treatment. The obtained nanocomposites have been characterized by TEM, while the surface morphology before and after treatment and homogeneous distribution of used consolidation materials on stone surface were examined by SEM. Improvement of stone mechanical properties was evaluated by compressive strength tests. Change in water-interaction properties was evaluated by water absorption capillarity measurements, and colorimetric measurements were used to evaluate the optical appearance. Taken together, the results indicate that CaCO3/polymer nanocomposite is a completely compatible, efficient material for the consolidation of artistic and architectural limestone monuments capable of enhancing the

Stable isotope compositions of quartz pebbles and their fluid inclusions as tracers of sediment provenance: Implications for gold- and uranium-bearing quartz pebble conglomerates

1992-09-01

Oxygen isotope compositions of pebbles from late Archean to paleo-Proterozoic gold- and/or uranium-bearing oligomictic quartz pebble conglomerates of the Witwatersrand district, South Africa, and Huronian Supergroup, Canada, were determined in an attempt to define the nature of the source terrain. The [delta][sup 18]O values of quartz pebbles within any one sample typically vary by [approximately] 4[per thousand] or more, but occasionally by as much as 8[per thousand], even for adjacent pebbles within the same hand specimen. In addition, adjacent quartz pebbles of widely contrasting [delta][sup 18]O values also preserve distinct isotopic signatures of their fluid inclusions. This overall heterogeneity suggests that the pebbles did not undergo significant oxygen isotope exchange after incorporation in the conglomerates. Therefore, oxygen isotope analyses of such quartz pebbles, in combination with a detailed investigation of their mineral and fluid inclusions, can provide a useful method for characterizing pebble populations and hence dominant sediment source modes. Comparison of values found in this study with [delta][sup 18]O values of quartz from Archean granites, pegmatites, and mesothermal greenstone gold veins, i.e., [delta][sup 18]O values of sources commonly proposed for the conglomerate ores, suggests that uranium is derived from a granitic source, whereas gold has a mesothermal greenstone gold source. Low [delta][sup 18]O values of chert pebbles (9[per thousand] to 11.5[per thousand]) relative to those expected for Archean and Proterozoic marine cherts (commonly [ge] 17[per thousand]) effectively exclude marine cherts, and therefore, auriferous iron formations and exhalatives, as likely sources of gold.

Rasmussen, S.E.

1977-01-01

Three boreholes were drilled in the west, central, and eastern sections of the Durban Roodepoort Deep Mine, and twelve distinct strata were intersected. Twenty-two samples from the three borehole cores were analysed in triplicate for twenty-six elements, and, including standards, a total of 2000 determinations were made. Statistical analysis of the results obtained for twenty-four elements shows a successful back-classification of 98 per cent, whereas, if the conglomerates or quartzites are treated separately, 100 per cent success is obtained. When the present data are used for classification of the samples from the three cores analysed during the first phase of this project, 100 per cent accuracy of classification is achieved by use of only ten selected elements. The objects of this investigation have therefore been met successfully, and extension to further strata and to sampling beyond the confines of the mine is justified [af

Cultural heritage is the evidence of the past; monumental objects create the important part of the cultural heritage. Selection of a method to be applied depends on many factors, which include: the objectives of inventory, the object's volume, sumptuousness of architectural design, accessibility to the object, required terms and accuracy of works. The paper presents research and experimental works, which have been performed in the course of development of architectural documentation of elements of the external facades and interiors of the Wilanów Palace Museum in Warszawa. Point clouds, acquired from terrestrial laser scanning (Z+F 5003h) and digital images taken with Nikon D3X and Hasselblad H4D cameras were used. Advantages and disadvantages of utilisation of these technologies of measurements have been analysed with consideration of the influence of the structure and reflectance of investigated monumental surfaces on the quality of generation of photogrammetric products. The geometric quality of surfaces obtained from terrestrial laser scanning data and from point clouds resulting from digital images, have been compared.

Steinstraesser, A.; Kemmer, W.; Muth, H.

1979-01-01

In Thorotrast patients, chromosome aberrations of lymphocytes from peripheral blood are to be used as a biological dosimeter. To get a significant dose-effect relationship it is necessary to estimate the absorbed dose of a single lymphocyte during its exposure time. In individual cases only average values can be calculated, based on assumptions of special distributions of Thorotrast. At first effects of the size of Thorotrast conglomerates and of their space distribution on the α-radiation dose distribution in their surroundings are described in a model. Then this model is transferred to the real dimensions and the histological structures of lymph nodes bearing Thorotrast. In some individual cases the microdistribution of Thorotrast has been determined in lymph nodes. Some of these results are demonstrated. According to these Thorotrast distributions, calculation of real absorbed dose of lymphocytes are performed. These values can be used for setting up a dose-effect relationship for biological dosimetry

Investigations were carried out on foraminiferids and radiolaria from redeposited clasts within the conglomerates of the Konradsheim Formation (Gresten Klippen Zone) in the area of the Pöchlau hill, east of Maria Neustift. These shales and marls are of Middle to Late Jurassic and Early Cretaceous age. In the latter clasts, foraminiferal assemblages with Tritaxia ex gr. gaultina as well as radiolaria species Angulobracchia portmanni Baumgartner, Dictyomitra communis (Squinabol), Hiscocapsa asseni (Tan), Pseudodictyomitra lodogaensis Pessagno, Pseudoeucyrtis hanni (Tan), Rhopalosyringium fossile (Squinabol) were found. In one block from the uppermost part of the sequence there is an assemblage with Caudammina (H) gigantea, Rotalipora appenninica and Globotruncana bulloides. However, the brecciated character of this block and occurrence near a fault suggest that it was probably wedged into the conglomerates of the Konradsheim Formation during tectonic movements. In pelitic siliceous limestones below the Konradsheim Limestone radiolarian assemblages of Middle Callovian to Early Tithonian age were found. They enable correlation with the Scheibbsbach Formation. In a marly sequence, above the conglomeratic limestone, the foraminiferal assemblages contain taxa from mid-Cretaceous up to Paleocene. The present biostratigraphic investigation confirmed the previous stratigraphic assignments and imply clearly that the sedimentation of deposits similar to the Konradsheim Formation also occurred at the end of the Early Cretaceous and deposition of conglomeratic limestones within the Gresten Klippen Zone, and especially within the Konradsheim Formation, was repeated several times during the Late Jurassic and Early Cretaceous.

The occurrence, origin and stratigraphic significance of bone-bearing mudstone pellet conglomerates from the Beaufort group in the Jansenville district, Cape Province, South Africa

International Nuclear Information System (INIS)

Turner, B.R.

1981-01-01

The lack of useful lithostratigraphic markers in the Beaufort Group in the southern Karoo Basin has focused attention on the biostratigraphy of the sediments. As a result a more refined scheme of biostratigraphic classification is now possible which may prove useful in fixing the stratigraphic position of the uranium mineralized horizons. The most important mineralized horizon in the Beaufort West area (contains about 90 per cent of all known uranium occurrences) is associated with the Pristerognathus/Diictodon assemblage zone, but the way in which this relates to the important uranium occurrences farther east, between Graaff-Reinet and Jansenville, is uncertain because of the lack of biostratigraphic control. Vertebrate remains have recently been found in mudstone pellet conglomerates in Beaufort channel sandstones along the Bullrivier in the Jansenville District, in an area that is extensively mineralized. The sandstones were deposited as point bar sands within a meandering river system flowing towards the north-east. The rivers drained a dry, arid to semi-arid alluvial plain and were characterized by fluctuating discharge and periods of low or negligible flow. These conditions promoted flood scour and fill activity and the deposition of internal mudstone pellet conglomerates. Hydrodynamic considerations suggest that estimates of bone transport velocity from their hydrodynamically equivalent quartz sphere is of limited value and can seldom, if ever, be applied to fossil bone accumulations. Identification of the bones from the conglomerates indicates that they belong to the Dino-cephalia biozone and not the overlying Pristerognathus/Diictodon zone. This suggests that the lower part of the Beaufort succession (formerly the Tapinocephalus zone) extends farther east than previously thought, and that the main mineralized horizon in this area occurs lower down in the succession than that around Beaufort West

The decrease of surface energy of mineral substrates similar to those used in many stone monuments of cultural heritage by the application of protective polymer coatings along with the simultaneous increase of their surface roughness can increase their ability to repel water substantially. In this work, the effect of artificially induced roughness on the water repellency of mineral substrates coated with protective polymer films was investigated. Natural marble samples or home made calcium carbonate blocks were tried as the mineral substrates. The roughness increase was achieved by mineral chemical etching or by creation of nanoscale binary composition film on the substrate surface. PMMA and PFPE were the polymers used, while different-sized silica nanoparticles were employed for the production of the nanocomposite films. Examination of the coated and uncoated surfaces with profilometry and AFM and measurements of water contact angles reveal a pronounced effect of the surface roughness on water repellency. Especially in the case of nanocomposite coatings, the surfaces become super-hydrophobic. This result indicates that the nanoscale binary composition film scheme, which is characterized by its simplicity and low cost, is a suitable candidate for the water protection of stone-based monuments on large scale.

2001-06-01

Full Text Available Megalithic monuments have played dijferent roles throughout History. One of them has a spatial function, i.e. as landmarks. The aim of this paper has been to collect and analyse every written reference concerning Galician megaliths operating as landmarks between the 6th and 19th centuries AD. On this basis, the evolution of this social-territorial function of the monuments through time is reconstructed, and an interpretative hypothesis for this phenomenon is proposed. Finally, the importance of reviewing written sources as a methodology for archaeological survey and for studies of the topographic settings of monuments is emphasised.

A lo largo de la Historia, los monumentos megalíticos han desempeñado, entre otras, una función espacial, como marcos de territorio. Para este artículo se recogen y analizan las referencias escritas a megalitos gallegos funcionando como marcadores o identificadores espaciales, entre los siglos VI y XIX d.C.

Architecture and monument

Directory of Open Access Journals (Sweden)

Arjen Oosterman

2010-08-01

Full Text Available The relation between architectural history and heritage is ambiguous. Both domains are confronted with rapid changes in scale and complexity, leaving practitioners in both fields with the challenging task to provide new methods and a new vocabulary to enable research and communication. 70 years ago Nicolaus Pevsner could write about Lincoln cathedral and the bicycle shed to discern between architecture and building. These days not only housing and urban development have been accepted as ‘objects’ of research, in fact all material manifestation of human occupation, at least as far as design is involved, is considered worth studying. On the heritage side, developments are comparable: horizontally and vertically the domain has been enlarged tremendously: from a collection of ‘diamonds’ to complete cities, to landscapes and structures. This is not only true for scale and layers, but also for cultural norms of quality. Cultural relativism requires that ‘beauty’ and ‘quality’ are defined in relation to the social group or culture they refer to. The logic that an elite determines what is good and what is right is challenged by the notion that popular taste is in principle equal. So what does this do to our museum collections and lists of protected monuments? The consequences for architectural history are not yet clear. Including new realities like digital design and new fields of practice like the virtual, the knowledge base and toolbox of the architectural historian has to expand beyond the Renaissance ideal of the ‘uomo universale’.

The straight line hypothesis elaborated: case reference obesity, an argument for acidosis, oxidative stress, and disease conglomeration?

Science.gov (United States)

Berkemeyer, Shoma

2010-07-01

Studies report on the association between obesity and oxidative stress, with and without additional diseases. Macrophages in adipocytes, and hypoxia in adipose tissue have been suggested to explain how obesity can relate to oxidative stress. The straight line hypothesis using the lactic acid trap construct has been put forward to explain how proton imbalance can relate to obesity. Proton imbalance has been also reported to associate with the production of reactive oxygen species by inhibition of mitochondrial energy production. This review brings together existing literature and concepts to explain how obesity can relate to oxidative stress via protons, uniquely for itself or, as often observed, in conglomeration of additional diseases.

Visualizing a monumental past: Archeology, Nasser's Egypt, and the early Cold War.

Science.gov (United States)

Carruthers, William

2017-09-01

This article examines geographies of decolonization and the Cold War through a case study in the making of archeological knowledge. The article focuses on an archeological dig that took place in Egypt in the period between the July 1952 Free Officers' coup and the 1956 Suez crisis. Making use of the notion of the 'boundary object', this article demonstrates how the excavation of ancient Egyptian remains at the site of Mit Rahina helped to constitute Nasserist revolutionary modernity and its relationship to wider, post-Second World War political geographies. The dig took place as a result of an Egyptian-American collaboration designed to institute the possibility of archeology taking place along the lines of the Point Four modernization program promoted by the United States. The article discusses how this situation not only engendered contention surrounding the role of the international 'experts' appointed to run this excavation work, but also - and as a result - helped to constitute the monumental visual and material shape that archeological evidence relating to the Egyptian past could now take. Egypt's revolution sat within wider Cold War political struggles, yet the 'ground-up' realities of this relationship helped to constitute the sort of past (and future) monumentality proposed by Nasser's government.

In June of 1977, the La Mesa fire burned 15,270 acres in and around Frijoles Canyon, Bandelier National Monument and the adjacent Santa Fe National Forest, New Mexico. The Dome fire occurred in April of 1996 in Bandelier National Monument, burned 16,516 acres in Capulin Canyon and the surrounding Dome Wilderness area. Both canyons are characterized by extensive archeological artifacts, which could be threatened by increased runoff and accelerated rates of erosion after a wildfire. The U.S. Geological Survey (USGS) in cooperation with the National Park Service monitored the fires' effects on streamflow in both canyons. Copyright 2004 ASCE.

Monumentalizing Landscape: from present perceptions to the original meanings of Galician Megalithism (NW Iberian Peninsula

Directory of Open Access Journals (Sweden)

Criado Boado, Felipe

1998-06-01

Full Text Available The study of Landscape as social construction implies considering its economic and territorial dimensions, as much as its symbolic ones. A major topic in such kind of studies is to reconstruct the ways as natural and social space was perceived by past societies. We ought approach the project of building an Archaeology of Perception. One of the aims of such research programme would be to evaluate the effect of natural and artificial landscape features on past human observers. This paper will argue that a possible strategy for studying these dimensions of past landscapes could be based on the systematic analysis of visual features of the prehistoric monuments and in the characterization of the escenic effects and vistas related to them. A detailed analysis of the pattern of location of megalithic monuments, of their visibility and visibilization conditions, allow us to recognize certain regularities what display an intentional will to remark on the existence of the monument and provoke dramatic artificial effects. In such way we could approach a phenomenology of prehistoric perception without falling in mere subjetive solutions. This study is based in a systematic review of the megalithic monuments from Sierra de Barbanza (NW Iberia. Its final scope is proposing theoretical and methodological standpoints to approach these phenomena, but as well producing a case-study to reconstruct monumental strategies to shape cultural landscapes in Neolithic Europe and observe the diacrony (ie, continuities and changes of these traditions.

Carlo Terpolilli

2012-04-01

Full Text Available While protection of our collective monumental heritage is a value and an objective we pass along to future generations, at the same time it must be conceived of a commitment to making these assets available to citizens of the present time. This means applying the disciplines of preservation and restoration and at the same time going beyond with a cultural approach that interprets the monumental asset as a fabbrica; that is, as a place of ongoing design activity: a workshop for a work in progress. This approach necessitates programs for valorization and productive investments that operate in full respect of the assets themselves while employing the innovative tools available for ensuring that the asset as a whole produces income. This is the framework for the MUDI project in Florence.

Public works: Building a Monument to Modern Buenos Aires

Directory of Open Access Journals (Sweden)

Anayvelyse Allen-Mossman

2016-12-01

Full Text Available Understanding the relationship between the project of modernity and urbanism has been key to understanding the city of Buenos Aires’ material transformations throughout the 20th century. This paper considers how thinking about the issues of modernity and urbanism from the perspective of monuments--namely, the Obelisk of Buenos Aires--sheds new light on how elements of this modernizing project were undertaken and how its material markers have been used and manipulated, and modified through their representation in cultural discourse on the city. Rethinking Buenos Aires from the Obelisk implies literally thinking from underground, from the subway lines that form its base and transform it into a popular symbol of mobility.

Full Text Available The work was carried out in four hectares of the «Monument National» Bosque Piedra Isabel Rubio, belonging to the Forest Company Macurije municipality Guane. Ecosystem that possesses national significance because it constitutes a valuable monumental example, it summarizes natural aspects as their calcareous formations of the Jurassic period, besides their intangible values associated to the rural traditions. The objective of the research is to propose a plan of action participative for the restoration of this ecosystem starting from the results obtained in diagnose participative. Among the used scientific methods, they are the research Action Participative and the participant observation, for the collection of information the interview was used in depth, and the meetings in groups. As important results the presence of a strong pressure antropic is obtained on the flora, fauna and rocks of the minimogotes, the introduction of exotic and invasive species, and soil erosion, in consequence the degradation of the ecosystem and loss of the biodiversity. Another significant result constituted it the scarce level of the actors' knowledge regarding the category of this forest and the administrative juridical regulations that govern it. The removed evidences of these communities show that the necessity to diminish the antropics actions and to elevate the sensibility regarding the conservation, they impose a demand of knowledge to satisfy by means of training actions with the participation of the local actors and instrumentation of the regulative apparatus.

Phase II, Title I engineering assessment of inactive uranium mill tailings, Monument Valley site, Monument Valley, Arizona

International Nuclear Information System (INIS)

1977-01-01

An engineering assessment was made of the problems resulting from the existence of radioactive uranium mill tailings at the Monument Valley millsite in Arizona. The Phase II, Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals residing nearby, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the tailings on the site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The sparse population and relatively low radiation levels yield minimal immediate environmental impact; hence, the two alternative actions presented are directed towards restricting access to the site and returning the windblown tailings to the pile and stabilizing the pile. Both options include remedial action costs for offsite locations where tailings have been placed. Cost estimates for the two options are $585,000 and $1,165,000

Museum Institutions in Monuments - Positive and Negative Aspects of Adaptation: The New Amber Museum and Museum of Science in Gdansk, Poland

Science.gov (United States)

Piatkowska, Ksenia

2017-10-01

The issue of the creation and location of new museums is a current topic. The decision of where and how to create new museum facilities will impact successful function in the future. Museums are either located in newly designed buildings or in existing buildings. In general, existing buildings adapted for museum use are either formally under conservational protection or not. With regard to museum location in preserved monuments, the author notes that the true impact on authentic monumental building structure still needs intense research. The adaptation of the Great Mill and St. Catherine’s Church - two preserved medieval objects located in the historical city center of Gdansk - provide case studies to investigate positive and negative aspects. In both cases, the author carried out architectural projects for the functional purposes of museums: The New Amber Museum and Museum of Science. The author concludes that mutual benefits of adaptation result from: the financial means of the museum institution to invest long-term; the institutional respect of the museum towards heritage, which translates into respect for conservational protection; and the competitive advantage created by the monumental features of the building and the privileged location in a well-established, branded space. Negative aspects result from: space limitations of monuments that disable the museum from extending its exposition and thus prevent institutional development; the overly restrictive requirements of restoration that take priority over the museum mission; and the lack of technically functional space required for contemporary museum technologies, which forces unconventional engineering solutions that are more expensive than the location of the museum in a newly constructed building.

Dating ancient monuments by nuclear radiation

International Nuclear Information System (INIS)

Goedicke, C.

2000-01-01

In the fifties and sixties several disciplines dealing with chronologies but lacking precise methods of measurements (geology, biology, archaeology and art history) became aware of the radioactive decay as a tool of measuring elapsed time. Among the disciplines that benefit most from physical methods archaeology has to be named first. So was archaeological work revolutionised by the introduction of the C-14 dating method. A wider selection of material became datable after the introduction of luminescence techniques using the effect of nuclear radiation on semiconductors. These minerals are widespread among archaeological materials. In ancient monuments, the objective of this paper, semiconductors almost exclusively form the material basis. Over the last four millennia wood, stone, mortar and fired bricks have been used for the construction of buildings. After discussing methods taking wood as a dating material, a broader view will be given on the results achieved by luminescence dating of fired bricks, mortar and stone. For many years brick dating was performed by thermoluminescence, the recipes followed those of ceramic dating. Preferably multiple aliquot additive dose protocols were used on polymineral fine grain fractions (1-10 μm). It was expected that the error in dating monuments would be smaller compared to ceramic dating, because of the constancy of the environmental conditions which a brick experiences during its lifetime. However, the variability of firing temperatures in brick kilns overthrows this advantage. Therefore, the demands of art historians to fall short of an error margin of 5% could generally not be fulfilled. Especially in medieval or renaissance times the temporal resolution of thermoluminescence is inferior to traditional stylistic dating as long as specific stylistic forms are present. New optical luminescence techniques and a new philosophy of dose evaluation, based on single aliquot regeneration protocols, produce less scatter, and in

Knowledge of the chemical composition of the building materials of the monuments may help us to preserve and protect them from the pollution of our cities. The aim of this work is to characterize the materials of the walls from ancient buildings, the decay products that could be appear due to the action of pollution and a new method based on nanomaterials (hydroxyapatite -HAp) for a conservative preservation of the treated walls. Some analytical techniques have been used, as follow: X-ray fluorescence energy dispersive (EDXRF) (for the relative abundance of major, minor and trace elements), FTIR and Raman spectroscopy (for stratigraphic study of cross-sections of multi-layered materials found in wall paintings), Optical microscopy (OM), (for morphology of the wall samples). The nanomaterial suspension HAp applied on the sample surface by spraying, decreased the capillary water uptake, do not modify significantly the color of the samples and induced a reduced mass loss for the treated samples.

CONTESTED HERITAGE: AN ANALYSIS OF THE PHYSICAL TRANSFORMATION OF DERRY/LONDONDERRY’S SIEGE MONUMENT

Directory of Open Access Journals (Sweden)

Gehan Selim

2017-11-01

Full Text Available Transformations of Derry/Londonderry’s medieval city walls during the twentieth century have shaped an urbanism of segregated settlements within a city of religious confrontation. The heritage of military blockades, peace lines and watchtowers imposed upon the city’s Walls has influenced the disintegration of public space and created areas of no man’s land around the peripheries of the monument. The aim of this paper is to examine physical transformation and trace the consequences of urban planning regarding the historic city Walls. This change includes the shifting of residential settlements in the Bogside/Fountain areas and the movement of Protestant settlements towards the Waterside of Derry/Londonderry. The history and heritage of the Walls are analysed by focusing on four periods: 1600, when the first medieval walls were constructed; the housing crisis of 1948; the 1968 urban area plan and the beginning of the ‘Troubles’; and the present day. This analysis offers an understanding of the spatial relationships between enclaves and the monument over key moments of conflict and political change. The paper reveals that the manifestations of the Walls have aided in the further division of religiously segregated communities in Derry/Londonderry.

Preliminary hydrogeologic assessment near Tassi and Pakoon Springs, western part of Grand Canyon-Parashant National Monument, Arizona

Science.gov (United States)

Truini, Margot

2013-01-01

Tassi and Pakoon Springs are both in the Grand Wash Trough in the western part of Grand Canyon-Parashant National Monument on the Arizona Strip. The monument is jointly managed by the National Park Service (NPS) and the Bureau of Land Management. This study was in response to NPS’s need to better understand the influence from regional increases in groundwater withdrawals near Grand Canyon-Parashant on the groundwater discharge from Tassi and Pakoon Springs. The climate of the Arizona Strip is generally semiarid to arid, and springs in the monument provide the water for the fragile ecosystems that are commonly separated by large areas of dry washes in canyons with pinyon and juniper. Available hydrogeologic data from previous investigations included water levels from the few existing wells, location information for springs, water chemistry from springs, and geologic maps. Available groundwater-elevation data from the wells and springs in the monument indicate that groundwater in the Grand Wash Trough is moving from north to south, discharging to springs and into the Colorado River. Groundwater may also be moving from east to west from Paleozoic rocks in the Grand Wash Cliffs into sedimentary deposits in the Grand Wash Trough. Finally, groundwater may be moving from the northwest in the Mesoproterozoic crystalline rocks of the Virgin Mountains into the northern part of the Grand Wash Trough. Water discharging from Tassi and Pakoon Springs has a major-ion chemistry similar to that of other springs in the western part of Grand Canyon-Parashant. Stable-isotopic signatures for oxygen-18 and hydrogen-2 are depleted in the water from both Tassi and Pakoon Springs in comparison to other springs on the Arizona Strip. Tassi Spring discharges from multiple seeps along the Wheeler Fault, and the depleted isotopic signatures suggest that water may be flowing from multiple places into Lake Mead and seems to have a higher elevation or an older climate source.

Monuments of the Giza Plateau

Science.gov (United States)

Ruggles, Clive L. N.

The colossal pyramids of the pharaohs Khufu (Cheops), Khafre (Chephren), and Menkaure (Mycerinus) have attracted a huge amount of astronomical interest over the years, both scholarly and popular. Less attention is usually given to the broader context of structures on the Giza Plateau. One of the most notorious ideas connecting the Giza Plateau with astronomy is that the three large pyramids are laid out on the ground so as to reflect the appearance of the three stars of Orion's Belt in the sky. This idea is unsupportable for several reasons but has succeeded in generating huge public interest. Of much greater serious interest is the fact that the three main pyramids were oriented cardinally to extraordinary precision, which raises the questions of why this was important and how it was achieved. Another idea that has attracted serious attention but also some confusion is that the orientations of some narrow shafts within Khufu's pyramid might have been deliberately aligned upon particular stars. The overall layout of monuments on the plateau may certainly have been designed so as to emphasize certain solar phenomena, for symbolic and ideological reasons relating to a dominant sun cult. It is also possible that it formed part of a wider cosmological "master plan" extending to other pyramids and temples up to 20 km distant.

From the Palais des Papes in Avignon to the 'Chateau d'eau Perret' at Saclay: study of historical monuments to understand the long term behaviour on metal/concrete interface

International Nuclear Information System (INIS)

L'Hostis, V.; Dillmann, Ph.; Chitty, W.J.; Millard, A.; Faquin, R.

2007-01-01

Corrosion of reinforcement is one of the major causes of concrete cracking and degradation of reinforced concrete structures in atmospheric environments. The life time of several reinforced concrete buildings (civil engineering, nuclear infrastructures, bridges, historical monuments...) depends on the interaction between metallic and cementitious materials. For instance, historical monuments contain an important quantity of iron since the roman period (30 tons for the dungeon of the 'Chateau de Vincennes', 100 tons for the Palais des Papes in Avignon), and play a role in the mechanical behaviour of the building. It is then necessary to determine the degradation state of metallic objects submitted to corrosion and to predict their behaviour with time. In this context, this paper shows how analysis of the metal/cementitious materials interface from a corpus of historical monuments allows to understand the corrosion mechanisms and to model them. Moreover, corrosion rates and products that are characterized can be used as input data for a macroscopic mechanical damage model of reinforced concrete submitted to corrosion of steels. This model is able to predict the cracking pattern of the monument. (authors)

Sulfur measurements in different age groups of pinon pine needles and adjacent soil samples from ten sampling sites at Bandelier National Monument were determined using combustion elemental analysis and chromatographic techniques. The primary goal was to establish base-line levels for elemental sulfur in the Monument. Sulfur levels in foliage and soils were evaluated using analysis of variance techniques. Foliage sulfur concentrations differed significantly among the 10 sampling sites and among trees within sites; however, needles of different ages did not differ significantly in sulfur content. Average soil concentrations were very low, approximately 12% of the average needle concentrations. Soil sulfur concentrations also differed significantly among the 10 sampling sites and at different depths in the soil. No statistical differences were evident in soils sampled at the four compass points (N,S,E,W) around each tree. These differences imply that large numbers of samples are needed to identify small effects from anthropogenic inputs of sulfur into the system or that the effects must be large relative to the differences among sampling sites and individual trees in order to be detected

The «discorso per immagini» of Superstudio: from Continuous Monument to Supersurface, 1968-1971

Directory of Open Access Journals (Sweden)

Beatrice Lampariello

2016-06-01

With a Christmas card from 1968 in the form of a poster, Superstudio inaugurated the production of photomontages which were to bring fame to the group. It is, however, for the competition dedicated to the theme of Architecture and Freedom, launched in 1969 by the Tri-National Biennial of Graz, that photomontage became the preferred graphical tool for the construction of a «discorso per immagini» for Superstudio, a narrative in which project descriptions and traditional forms of architectural representation are replaced by images representing enigmatic volumes, seemingly devoid of function and open to multiple interpretations. Compared to similar and contemporary images produced, amonst others, by Archigram and Yona Friedman, the photomontages of Superstudio do not intend to give veracity to futuristic urban and territorial visions. The impenetrable volumes, designed beyond any program or structural logic, are an expression of absolute rationality and order which Superstudio has been searching for its founding to ward off the crisis and to ward for uncertainty of contemporary era. Graphic techniques used by the group for their representations evolved over the years, and were adapted to achieve different effects, all still oriented to building a strong environmental realism, as far away as possible from comic and surprising effects. Through the «discorso per immagini» the theory of the group became eloquent: after having imagined a new form of land occupation designed as a monumental infinite linear structure that crosses cities and virgin landscapes – the Continuous Monument – Superstudio staged the dissolution of conventional boundaries of architecture, to move towards its «non-physical» re-foundation. After all, the «happy death of architecture should not frighten anybody: we have been preparing for long, increasingly distancing ourselves from the physicality of the construction», as revealed by one of the members of the group in 1971.

Digital heritage data are now more accessible through crowdsourcing platforms, social media and blogs. At the same time, evolving technology on 3D modelling, laser scanning and 3D reconstruction is constantly upgrading and multiplying the information that we can use from heritage digitalisation. The question of reusing the information in different aspects rises. Educators and students are potential users of the digital content; developing for them an adaptable environment for applications and services is our challenge. One of the main objective of the EU Europeana Space project is the development of a holistic approach for educating people (grown ups and kids) on Monuments that are listed at UNESCO world heritage list, in Cyprus. The challenge was the use of Europeana Data (Pictures and the 3D objects) in a way that the information on the platform would be comprehensible by the users. Most of the data have little metadata information and they lack history and cultural value description (semantics). The proposed model ction is based on the cross cultural approach which responds to the multicultural features of present era but at the same time to the contemporary pedagogical and methodological directions. The system uses all innovative digital heritage resources, in order to help the user, in a UX friendly way, to learn about the different phases of the monument, the history, the pathology state, the architectural value and the conservation stage. The result is a responsive platform, accessible through smart devices and desktop computers, (in the frame of "Bring Your Own Device" a.k.a. BYOD) where every Monument is a different course and every course is addressed to different age groups (from elementary level to adults' vocational training).

Surveillance for White-Nose Syndrome in the bat community at El Malpais National Monument, New Mexico, 2011

Valdez, Ernest W.

2012-01-01

From late winter to summer 2011, the U.S. Geological Survey Arid Lands Field Station conducted mist-netting efforts at El Malpais National Monument and on adjacent lands belonging to Bureau of Land Management and U.S. Forest Service to detect the occurrence of white-nose syndrome or causal fungal agent (Geomyces destructans). During this assessment, 421 bats belonging to 8 species were documented at El Malpais National Monument and adjacent lands. None of these captures showed evidence for the presence of white-nose syndrome or G. destructans, but it is possible that the subtle signs of some infections may not have been observed. Throughout the field efforts, Laguna de Juan Garcia was the only water source located on El Malpais National Monument and was netted on June 20 and 27, July 25, and August 2, 2011. During these dates, a total of 155 bats were captured, belonging to eight species including: Corynorhinus townsendii (Townsend's Big-Eared Bat), Eptesicus fuscus (Big Brown Bat), Lasionycterics noctivagans (Silver-Haired Bat), Myotis ciliolabrum (Small-Footed Myotis), M. evotis (Long-eared myotis), M. thysanodes (Fringed Myotis), M. volans (Long-Legged Myotis), and Tadarida brasiliensis (Brazilian Free-Tailed Bat). Overall, Laguna de Juan Garcia had the greatest number of captures (79 bats) during one night compared to the other sites netted on adjacent lands and had the greatest species diversity of 8 species netted, not including Euderma maculatum (Spotted Bat) that was detected by its audible calls as it flew overhead. Laguna de Juan Garcia is an important site to bats because of its accessibility by all known occurring species, including the less-maneuverable T. brasiliensis that is known to form large colonies in the park. Laguna de Juan Garcia is also important as a more permanent water source during drought conditions in the earlier part of the spring and summer, as observed in 2011.

2000-01-01

A 'Laboratory of Quantitative Methods in Monument Research' is being built at the CTU Prague. Its primary orientation is the investigation of historic architecture, although other objects of art can also be investigated. In the first phase, two radiation methods are being established, but it is set up in such a way, that various other methods can readily be added in its future development. The radiation methods chosen for the initial development of the laboratory are: thermoluminescence dating and X-ray fluorescence analysis. The design of the automated TL-reader, built in our laboratories, is adjusted for the purpose of dating of historic brick architecture (which, of course, does not exclude applications for ceramics and other materials). The investigation of renaissance architecture in southern Bohemia and Moravia is under preparation as the first large campaign of this kind in the Czech Republic. Radionuclide X-ray fluorescence analysis has been chosen as the basic analytical method in the laboratory. The possibility of analyses of paintings and fired building materials (bricks, roof tiles) have been investigated. The first results in both the areas are very promising

2004-01-01

Radionuclide X-ray fluorescence analysis (RXRFA), as a non-destructive method, relatively simple and allowing measurements to be carried out in situ, is an excellent tool in research on various objects of art. A range of artefacts have been investigated by our laboratory, in part for the purposes of history of art and in part as a basis for restoration works - medieval frescoes in some Czech castles and churches, metal sculptures and objects of applied art, paints and inks of old manuscripts, paintings. Some of these are among the most valuable monuments in the Czech cultural heritage. The contribution of the results of the tests to the investigation of their 'life story' and, in some cases, to their conservation, is not negligible. Later additions and repairs can be recognised, and materials and technologies that are close to their historic counterparts can be used in restoration work

Miller, Lisa D.; Stogner, Sr., Robert W.

2017-09-01

From 2007 through 2015, the U.S. Geological Survey, in cooperation with Colorado Springs City Engineering, conducted a study in the Fountain and Monument Creek watersheds, Colorado, to characterize surface-water quality and suspended-sediment conditions for three different streamflow regimes with an emphasis on characterizing water quality during storm runoff. Data collected during this study were used to evaluate the effects of stormflows and wastewater-treatment effluent discharge on Fountain and Monument Creeks in the Colorado Springs, Colorado, area. Water-quality samples were collected at 2 sites on Upper Fountain Creek, 2 sites on Monument Creek, 3 sites on Lower Fountain Creek, and 13 tributary sites during 3 flow regimes: cold-season flow (November–April), warm-season flow (May–October), and stormflow from 2007 through 2015. During 2015, additional samples were collected and analyzed for Escherichia coli (E. coli) during dry weather conditions at 41 sites, located in E. coli impaired stream reaches, to help identify source areas and scope of the impairment.Concentrations of E. coli, total arsenic, and dissolved copper, selenium, and zinc in surface-water samples were compared to Colorado in-stream standards. Stormflow concentrations of E. coli frequently exceeded the recreational use standard of 126 colonies per 100 milliliters at main-stem and tributary sites by more than an order of magnitude. Even though median E. coli concentrations in warm-season flow samples were lower than median concentrations in storm-flow samples, the water quality standard for E. coli was still exceeded at most main-stem sites and many tributary sites during warm-season flows. Six samples (three warm-season flow and three stormflow samples) collected from Upper Fountain Creek, upstream from the confluence of Monument Creek, and two stormflow samples collected from Lower Fountain Creek, downstream from the confluence with Monument Creek, exceeded the acute water

Full Text Available Abstract Monuments play a key role in the formation of a common memory and community consciousness by symbolizing important events or situations in the lives of people and societies and establish diverse dialogues with their surroundings in this context. The monument-art works to be placed in open spaces are important in terms of shaping social life and fulfill functions such as warning and activating society. For this reason, the use of monuments in open spaces is a matter for landscape architects to explore. The aim of the study is to determine the purposes and functions of monuments in urban open spaces. In this context, monuments in the city center of Trabzon are photographed and their usage types are classified. As a result, the monuments in urban open spaces in Trabzon are mostly composed of Atatürk and the persons in the history of the city (Kanuni Sultan Süleyman, Yavuz Sultan Selim, Mimar Sinan Etc. And secondly the figures and events reflecting the culture of the city (horon/dancing figures, kamancha playing figures, anchovy, Trabzonspor etc. Finally, it is seen that the expressions (military, martyr, etc. reflect the national spirit. So in the monuments; it has been determined that the historical, cultural and social characteristics of the city are gaining more importance.   Öz Toplum ve bireylerin yaşamında yer alan önemli olayları simgeleyen, ortak toplumsal bilinç ve hafıza oluşturan heykeller çevreleriyle ilişki kurarlar.

When considering the various possibilities to assess the effects of SO{sub 2} and NO{sub 2} on historic buildings and monuments, a distinction can be made according to the completeness of the scope of the assessment itself. A first approach can be limited to gathering data as they become available through the official bodies established under air quality legislation. This approach is based on a single point measurement where a general purpose monitoring station is located, often quite far from the monument to protect and often without investigating local and temporal variations. A more comprehensive assessment should include a generalisation that covers the territory. This can be made on the basis of the knowledge of the spatial distribution of concentrations and the knowledge of the causes of air pollution. Passive samplers allow the measurement of air quality in numerous sites and to assess the pollutant spatial distribution over a large area with a high resolution. As an application of the method, the spatial distribution of SO{sub 2} and NO{sub 2} in the city of Siracusa, Sicily, Italy, has been studied to identify areas of high deposition fluxes in relation to the protection of buildings and monuments of the historic centre. [Italian] E' noto che gli inquinanti presenti in aria, tra questi in particolare l'SO{sub 2} e l'NO{sub 2}, sono causa di danno sui monumenti e sulle opere d'arte. La valutazione dell'impatto di questi due inquinanti viene solitamente effettuata sulla base del monitoraggio eseguito secondo la legislazione vigente ma spesso lontano dal monumento da proteggere. Cio', evidentemente, non consente di valutare correttamente il grado di rischio al quale un monumento e' esposto poiche' non fornisce informazioni sulle variazioni spaziali e temporali dei due inquinanti in prossimita' del monumento stesso. Allo scopo di raccogliere quindi informazioni complete sulla distribuzione degli inquinanti, e

Assessment of the radiological impact of the inactive uranium-mill tailings at Monument Valley, Arizona

Haywood, F.F.; Goldsmith, W.A.; Hubbard, H.M. Jr.; Fox, W.F.; Shinpaugh, W.H.

1979-12-01

Results of a radiological survey that was conducted at the inactive uranium-mill site at Monument Valley, Arizona, in March 1976, in cooperation with a team from Ford, Bacon and Davis Utah Inc., are presented. Consideration of these data and of previously published information on radiological conditions at the site lead to the conclusion that potential health effects from exposure to radionuclides in the mill tailings are relatively small. The occupants of three residences within 0.8 km (0.5 mile) of the tailings constitute the principal population at risk, but direct gamma-exposure rate measurements near the two residences closest to the tailings and calculations of radon dispersion indicate that the tailings do not raise either pathway of radiation exposure significantly above the background level. Data are not available to evaluate fully other possible exposure pathways, but the available information indicates that it is unlikely that doses through these pathways will add significantly to the total population dose. The low estimates of potential health effects from exposure to direct radiation and to exposure to radionuclides in the Monument Valley tailings piles are ascribed to the low 226 Ra inventory, to almost complete absence of small particles that are readily moved by wind and water, and to a small population in the vicinity of the tailings

NIPGAT: new tool for investigating the deterioration of monuments and historic buildings

2004-01-01

The degradation of some building materials such as brick and mortar is a major problem for the preservation of monuments or historic structures, especially where it is desirable to preserve the original fabric of the building. Such degradation often arises from the presence of contaminants in the constituent materials. Knowledge of the presence and distribution of contaminants is needed for effective treatment and preservation. In building materials, water and soluble salt are considered two unwanted contaminants. Their concentrations and distribution in these materials are very important factor in estimating the degree of building deterioration. Water is a major course of deterioration, both by acting as a solvent for various building materials components and by exerting stresses on the structure during thermal cycle. The soluble salts, notably chlorides, damage the structure either by periodically dissolving and recrystallising within the pores or by promoting corrosion. Neutrons are useful as probes for non-destructive examination of extended media because neutrons can travel relatively long distances before interacting with the nuclei of the media. Depending on the type of material, neutrons can have a mean free path of tens of centimeters to meters. It is for this reason that neutrons in conjunction with gamma-ray spectroscopy have been used extensively in oil-well logging and mineral exploration. For the same reason, a new method, called neutron-induced prompt gamma-ray technique, NIPGAT is being developed at MINT for preservation of monuments and historic buildings. NIPGAT can be used for in-situ quantitative determination and location of contaminants, particularly water and soluble salt in building materials. This paper presents a brief overview and gives preliminary results of NIPGAT research activities at MINT. It is hoped that it may raise awareness and promote further opportunities for the collaboration of the nuclear research scientists with the museum

Full Text Available Tsunamis related to volcano flank collapse are typically a high-magnitude, low frequency hazard for which evaluation and mitigation are difficult to address. In this short communication, we present field evidences of a large tsunami along the southern coast of Mauritius Island ca. 4400 years ago. Tsunami deposits described include both marine conglomerates and coral boulders up to 90 m3 (> 100 tons. The most probable origin of the tsunami is a flank collapse of Piton de la Fournaise volcano, Réunion Island.

Ground-Water Flow Direction, Water Quality, Recharge Sources, and Age, Great Sand Dunes National Monument, South-Central Colorado, 2000-2001

Science.gov (United States)

Rupert, Michael G.; Plummer, Niel

2004-01-01

Great Sand Dunes National Monument is located in south-central Colorado along the eastern edge of the San Luis Valley. The Great Sand Dunes National Monument contains the tallest sand dunes in North America; some rise up to750 feet. Important ecological features of the Great Sand Dunes National Monument are palustrine wetlands associated with interdunal ponds and depressions along the western edge of the dune field. The existence and natural maintenance of the dune field and the interdunal ponds are dependent on maintaining ground-water levels at historic elevations. To address these concerns, the U.S. Geological Survey conducted a study, in collaboration with the National Park Service, of ground-water flow direction, water quality, recharge sources, and age at the Great Sand Dunes National Monument. A shallow unconfined aquifer and a deeper confined aquifer are the two principal aquifers at the Great Sand Dunes National Monument. Ground water in the unconfined aquifer is recharged from Medano and Sand Creeks near the Sangre de Cristo Mountain front, flows underneath the main dune field, and discharges to Big and Little Spring Creeks. The percentage of calcium in ground water in the unconfined aquifer decreases and the percentage of sodium increases because of ionic exchange with clay minerals as the ground water flows underneath the dune field. It takes more than 60 years for the ground water to flow from Medano and Sand Creeks to Big and Little Spring Creeks. During this time, ground water in the upper part of the unconfined aquifer is recharged by numerous precipitation events. Evaporation of precipitation during recharge prior to reaching the water table causes enrichment in deuterium (2H) and oxygen-18 (18O) relative to waters that are not evaporated. This recharge from precipitation events causes the apparent ages determined using chlorofluorocarbons and tritium to become younger, because relatively young precipitation water is mixing with older waters

Metal exposure and effects in voles and small birds near a mining haul road in Cape Krusenstern National Monument, Alaska.

2010-11-01

Voles and small passerine birds were live-captured near the Delong Mountain Regional Transportation System (DMTS) haul road in Cape Krusenstern National Monument in northwest Alaska to assess metals exposure and sub-lethal biological effects. Similar numbers of animals were captured from a reference site in southern Cape Krusenstern National Monument for comparison. Histopathological examination of selected organs, and analysis of cadmium, lead, and zinc concentrations in liver and blood samples were performed. Voles and small birds captured from near the haul road had about 20 times greater blood and liver lead concentrations and about three times greater cadmium concentrations when compared to those from the reference site, but there were no differences in zinc tissue concentrations. One vole had moderate metastatic mineralization of kidney tissue, otherwise we observed no abnormalities in internal organs or DNA damage in the blood of any of the animals. The affected vole also had the greatest liver and blood Cd concentration, indicating that the lesion might have been caused by Cd exposure. Blood and liver lead concentrations in animals captured near the haul road were below concentrations that have been associated with adverse biological effects in other studies; however, subtle effects resulting from lead exposure, such as the suppression of the activity of certain enzymes, cannot be ruled out for some individual animals. Results from our 2006 reconnaissance-level study indicate that overall, voles and small birds obtained from near the DMTS road in Cape Krusenstern National Monument were not adversely affected by metals exposure; however, because of the small sample size and other uncertainties, continued monitoring of lead and cadmium in terrestrial habitats near the DMTS road is advised.

Seismic and Restoration Assessment of Monumental Masonry Structures

2017-08-01

Full Text Available Masonry structures are complex systems that require detailed knowledge and information regarding their response under seismic excitations. Appropriate modelling of a masonry structure is a prerequisite for a reliable earthquake-resistant design and/or assessment. However, modelling a real structure with a robust quantitative (mathematical representation is a very difficult, complex and computationally-demanding task. The paper herein presents a new stochastic computational framework for earthquake-resistant design of masonry structural systems. The proposed framework is based on the probabilistic behavior of crucial parameters, such as material strength and seismic characteristics, and utilizes fragility analysis based on different failure criteria for the masonry material. The application of the proposed methodology is illustrated in the case of a historical and monumental masonry structure, namely the assessment of the seismic vulnerability of the Kaisariani Monastery, a byzantine church that was built in Athens, Greece, at the end of the 11th to the beginning of the 12th century. Useful conclusions are drawn regarding the effectiveness of the intervention techniques used for the reduction of the vulnerability of the case-study structure, by means of comparison of the results obtained.

Horemans, B.; Schalm, O.; De Wael, K.; Cardell, C.; Van Grieken, R.

2012-07-01

The world famous Alhambra monument in Granada, Southern Spain, listed as UNESCO world cultural heritage since 1984, represents probably the most beautiful example of Islamic art and architecture from the Middle Ages in Europe. It is visited by ca. 2 million people annually. Granada is situated in a natural basin, surrounded by mountains with altitudes up to 3500 m. Due to this topography and the prevailing low wind speeds, pollution-derived and especially traffic-derived particulate matter often accumulates in the urban air. In order to evaluate the potential conservation risks from the surrounding air, the atmospheric composition in the Alhambra monument was evaluated. Indoor temperature and relative humidity fluctuations were evaluated for their potential degenerative effects. Furthermore, the atmospheric composition in the Alhambra was analyzed in terms of inorganic gases (NO2, SO2, O3, and NH3) and black carbon. It was found that the open architecture protected the indoor environments from developing a potentially harmful microclimate, such as the build-up of humidity resulting from the huge number of daily tourists. On the downside, the strong ventilation made the indoor air hardly different from outdoor air, as characterized by strong diurnal temperature and relative humidity gradients and high traffic-derived pollutant levels.

The world famous Alhambra monument in Granada, Southern Spain, listed as UNESCO world cultural heritage since 1984, represents probably the most beautiful example of Islamic art and architecture from the Middle Ages in Europe. It is visited by ca. 2 million people annually. Granada is situated in a natural basin, surrounded by mountains with altitudes up to 3500 m. Due to this topography and the prevailing low wind speeds, pollution-derived and especially traffic-derived particulate matter often accumulates in the urban air. In order to evaluate the potential conservation risks from the surrounding air, the atmospheric composition in the Alhambra monument was evaluated. Indoor temperature and relative humidity fluctuations were evaluated for their potential degenerative effects. Furthermore, the atmospheric composition in the Alhambra was analyzed in terms of inorganic gases (NO 2 , SO 2 , O 3 , and NH 3 ) and black carbon. It was found that the open architecture protected the indoor environments from developing a potentially harmful microclimate, such as the build-up of humidity resulting from the huge number of daily tourists. On the downside, the strong ventilation made the indoor air hardly different from outdoor air, as characterized by strong diurnal temperature and relative humidity gradients and high traffic-derived pollutant levels.

2010-01-01

Full Text Available Biofilm on the sandstone substrata of the bridge 'Brankov most' and on the granite substrata of the 'Monument of the Unknown Hero' contains a complex consortia of cyanobacteria, algae, and fungi. Coccoid and filamentous cyanobacteria, green algae and diatoms make up the photosynthetic part of the biofilm while hyphal fragments, chlamydospores, fruiting bodies and spores take part as fungal components. These structures make a dense layer by intertwining and overlapping the stone surface. Five cyanobacterial, 11 algal and 23 fungal taxa were found. The interaction of the biofilm's constituents results in the bioweathering of the stone substrata through mechanical penetration, acid corrosion and the production of secondary mycogenic biominerals. .

Central Asia is rich in cultural heritage generated by thousands of years of human occupation. Aiming for a better understanding of Central Asia’s archaeology and how this unique heritage can be protected, the region should be studied as a whole with regard to its cultural ties with China and combined efforts should be undertaken in shielding the archaeological monuments from destruction. So far, international research campaigns have focused predominantly on single-sites or small-scale surveys, mainly due to the bureaucratic and security related issues involved in cross-border research. This is why we created the Dzungaria Landscape Project. Since 2013, we have worked on collecting remote sensing data of Xinjiang including IKONOS, WorldView-2, and TerraSAR-X data. We have developed a method for the automatic detection of larger grave mound structures in optical and SAR data. Gravemounds are typically spatially clustered and the detection of larger mound structures is a sufficient hint towards areas of high archaeological interest in a region. A meticulous remote sensing survey is the best planning tool for subsequent ground surveys and excavation. In summer 2015, we undertook a survey in the Chinese Altai in order to establish ground-truth in the Hailiutan valley. We categorized over 1000 monuments in just three weeks thanks to the previous detection and classification work using remote sensing data. Creating accurate maps of the cemeteries in northern Xinjiang is a crucial step to preserving the cultural heritage of the region since graves in remote areas are especially prone to looting. We will continue our efforts with the ultimate aim to map and monitor all large gravemounds in Dzungaria and potentially neighbouring eastern Kazakhstan.

Water availability and flood hazards in the John Day Fossil Beds National Monument, Oregon

Frank, Frank J.; Oster, E.A.

1979-01-01

The rock formations of the John Day Fossil Beds National Monument area are aquifers that can be expected to yield less than 10 gallons of water per minute to wells. The most permeable of the geologic units is the alluvium that occurs at low elevations along the John Day River and most of the smaller streams. Wells in the alluvial deposits can be expected to yield adequate water supplies for recreational areas; also, wells completed in the underlying bedrock at depths ranging from 50 to 200 feet could yield as much as 10 gallons per minute. Pumping tests on two unused wells indicated yields of 8 gallons per minute and 2 gallons per minute. Nine of the ten springs measured in and near the monument area in late August of 1978 were flowing 0.2 to 30 gallons per minute. Only the Cant Ranch spring and the Johnny Kirk Spring near the Sheep Rock unit had flows exceeding 6 gallons per minute. Chemical analyses of selected constituents of the ground water indicated generally low concentrations of dissolved minerals. Although cloudbursts in the Painted Hills unit could generate a flood wave on the valley floors, flood danger can be reduced by locating recreational sites on high ground. The campground in Indian Canyon of the Clarno unit is vulnerable to cloudburst flooding. About 80 percent of the proposed campground on the John Day River in the Sheep Rock unit is above the estimated level of 1-percent chance flood (100-year flood) of the river. The 1-percent chance flood would extend about 120 feet from the riverbank into the upstream end of the campground. (USGS).

The authors report and comment data obtained by geochemical and mineralogical studies performed in several conglomerate-type uranium deposits located in South Africa and in Canada. These data display positive correlations between uranium enriching and that of thorium, rare earth notably. They compare the geochemical signature of uraninites of these conglomerates with that of granitoid uraninites of same age which could be their source. Measurements have been performed with an electronic microprobe for uranium oxide species and a ionic microprobe for rare earth contents. Different types of uranium-bearing minerals are identified which correspond to different mechanisms and origins of formation of uraninites

Noise impacts resources and visitor experience in many protected natural areas, and visitors can be the dominant source of noise. This experimental study tested the efficacy and acceptability of signs asking visitors to be quiet at Muir Woods National Monument, California. Signs declaring a "quiet zone" (at the park's Cathedral Grove) or a "quiet day" (throughout the park) were posted on a randomized schedule that included control days (no signs). Visitor surveys were conducted to measure the cognitive and behavioral responses of visitors to the signs and test the acceptability of these management practices to visitors. Visitors were highly supportive of these management practices and reported that they consciously limited the amount of noise they produced. Sound level measurements showed substantial decreases on days when signs were posted. © 2011 Acoustical Society of America

Full Text Available Orkhon Inscriptions is one of the largest cultural heritages of the Turkish nation. These cultural assets are the property of being the memory of the nation they were born through. Indeed since these monuments transfer the values they contain to the future, they have a characteristic that is the masterpiece of the Turkish nation which plays a significant role. What a nation keeps alive is its values. In this sense, for the Turkish nation, it is important that these monuments is examined in terms of the transfer value and is used in educational activities. The aim of this study is to identify the values in Tunyuquq Monument which is the first of Orkhon Inscriptions and to determine the importance of these values in Turkish value transfer. In the study, the descriptive analysis, one of the qualitative research techniques, has been used. By the researcher, values form was prepared in consultation with experts and the value elements in Tunyuquq Monument were determined and then with the problem of the study, the following conclusions were reached: ?\tIn Tunyuquq Monument, about 179 value elements have been identified, directly or indirectly, including 25 different values of the Turkish nation. These values and their handling frequencies in the Monument are given as follows: Bravery - bravery value (f = 24, Leadership value (f = 21, Nation-family unity value (f = 15, Homeland - the nation benefit (f = 15, Taking responsibility value (f = 12, Freedom and independence value (f = 11, Diligence value (f = 9; Farsightedness value (f = 9, belief in God value (f = 9; Sacrifice value (f = 7, Integrity value (f = 5, Sensitivity-kindness value (f = 5, Respect value (f = 5, Solidarity value (f = 4, Loyalty value (f = 4, Tradition-customs value (f = 4, Wisdom value (f = 4, Peace value (f = 3, comply with laws-law of value (f = 3, Protect the language value (f = 3, Patriotism value (f = 2, Esteeming Elder’s sayings value (f= 2, faithfulness value (f=1

Engineering assessment of inactive uranium mill tailings, Monument Valley site, Monument Valley, Arizona. A summary of the Phase II, Title I

International Nuclear Information System (INIS)

1977-01-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at the Monument Valley millsite in Arizona. The Phase II, Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals residing nearby, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the tailings on the site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation are also factors. The sparse population and relatively low radiation levels yield minimal immediate environmental impact; hence, the two alternative actions presented are directed towards restricting access to the site (Options I and II), and returning the windblown tailings to the pile and stabilizing the pile with 2 ft of cover material (Option II). Both options include remedial action costs for offsite locations where tailings have been placed. Cost estimates for the two options are $585,000 and $1,165,000. Reprocessing the tailings for uranium is not economically feasible

Certain local atmospheric anomalies, such as the formation of unusually large ice conglomerations (megacryometeors), have been proposed to be a potential natural hazard for people and aviation, as well as geoindicators for fingerprinting larger-scale atmospheric environmental changes. On March 13th 2007, at approximately 10:15 am, an ice chunk weighing about 10 kg fell from the clear-sky and crashed through the roof (around 15 m) of an industrial storage house in Mejorada del Campo, a town located 20 km east from Madrid. The megacryometeor monitoring follow-up and the original investigation presented here includes, for the first time, both logistic and scientific collaboration between the Laboratory of the Environment, Criminalistic Service (SECRIM, the Spanish "Guardia Civil") and academic and scientific institutions (universities and the Spanish National Research Council). We propose that the management procedure of the incident, along with the detailed scientific research and combination of analytical methodologies in different laboratories, can serve as a protocol model for other similar events.

Photocatalytic degradation of clofibric acid, carbamazepine and iomeprol using conglomerated TiO2 and activated carbon in aqueous suspension.

2010-01-01

The combination of powdered activated carbon (PAC) and TiO(2) has been tested for synergistic/antagonistic effects in the photocatalytic degradation of carbamazepine, clofibric acid and iomeprol. Synergistic effects are thought to be caused by rapid adsorption on the PAC surface followed by diffusion to the TiO(2) surface and photocatalytic degradation. The Freundlich constant K(F) was used for comparing the sorption properties of the three substances and it was found that K(F) for clofibric acid was 3 times lower than for carbamazepine and iomeprol, regardless of the kind of PAC used. A PAC with a distinct tendency to form conglomerates was selected so that a high percentage of the PAC surface was in direct proximity to the TiO(2) surface. The photocatalytic degradation of the pharmaceutically active compounds studied followed pseudo-first order kinetics. Synergistic effects only occurred for clofibric acid (factor 1.5) and an inverse relationship between adsorption affinity and synergistic effects was found. High affinity of the target substances to the PAC surface seemed to be counterproductive for the photocatalytic degradation.

Measuring change over time: the use of geotagged photographs to evaluate the weathering of monuments

Doehne, E.

2012-04-01

Evaluating the condition of weathered stone surfaces on a monument, building or sculpture requires information on how those surfaces have evolved. In a number of cases, the documentation related to a site or object is either not readily available or has been lost (due to war, fire, etc.). Exploring the use of geotagged photographs to supplement the evaluation of surface changes to monuments was tested using two sites: the Mausoleum at the Huntington Library, Art Collections, and Botanical Gardens in San Marino, California and the Duomo in Florence, Italy. Increasingly, photographs are being geo-located or geotagged, either automatically via GPS/WiFi or manually. Geolocation tags increase the value of a photograph to researchers by providing the geographic location where the image was taken, often along with the date and time the photograph was acquired. Estimates of the number of geolocated photographs posted to the Internet include 148 million on Flickr.com (as of June 3, 2011) increasing to 172 million as of January 15, 2012. On Panarimo.com five million geolocated images were archived as of October 2007. Tools such as auto-geotag and PhotoOverlay are making it easier for users to locate and exactly position existing photographs and historic photographs on sites such as Google Earth (PhotoOverlays are images that are directly embedded in the Google Earth's landscape). 42 photo sharing websites are listed currently on Wikipedia, with seven having Alexa rankings of less than 200, indicating the popularity of photo sharing and the vast nature of this resource. Preliminary results from the Huntington and the Duomo indicate that geolocated images are indeed a useful tool for aiding in understanding stone weathering patterns and changes over time. However, greater software support and new tools are needed to enable researchers to search, organize and analyze groups of photographs from a single geolocation. Such software would have obvious uses beyond the conservation

Radiological audit of remedial action activities at the processing sites Mexican Hat, Utah and Monument Valley, Arizona. Audit date: May 3--7, 1993, Final report

International Nuclear Information System (INIS)

1993-05-01

The Uranium Mill Tailings Remedial Action (UMTRA) Project's Technical Assistance Contractor (TAC) performed a radiological audit of the Remedial Action Contractor (RAC), MK-Ferguson and CWM Federal Environmental Services, Inc., at the processing sites in Mexican Hat, Utah, and Monument Valley, Arizona. This audit was conducted May 3--7, 1993, by Bill James and Gerry Simiele of the TAC. Three site-specific findings and four observations were identified during the audit and are presented in this report. The overall conclusion from the audit is that the majority of the radiological aspects of the Mexican Hat, Utah, and Monument Valley, Arizona, remedial action programs are performed adequately. However, the findings identify that there is some inconsistency in following procedures and meeting requirements for contamination control, and a lack of communication between the RAC and the DOE on variances from the published remedial action plan (RAP)

Isolation and characterisation of barium sulphate and titanium oxides in monument crusts

Energy Technology Data Exchange (ETDEWEB)

Luis Perez-Rodriguez, Jose; Carmen Jimenez de Haro, Maria del; Maqueda, Celia

2004-10-25

Black crusts from historical ornamental materials contain Ba and Ti. These elements are in low proportion, making their determination difficult and especially the characterisation of the phases in which they are present. For this reason, works on the mineralogical composition of the two elements in black crusts is scarce. Thus the isolation, previous to their characterisation, is important for the study of the surface layer in altered monuments. An acid attack for the isolation of barium sulphate and titanium oxides in black crusts from polluted areas has been used. The acid employed is a mixture of HF, HNO{sub 3} and HClO{sub 4}. The residue isolated by acid attack was analysed by energy dispersive X-ray fluorescence and X-ray diffraction. It was characterised, and the percentages of barite (barium sulphate), anatase (titanium oxide), and rutile (titanium oxide) phases present in the surface layers were calculated.

Full Text Available Accessibility to cultural heritage is one of the most important factors in cultural heritage preservation, as it assures knowledge, monitoring, Public Administration management and a wide interest on cultural heritage sites. Nowdays 3D surveys give the geometric basis for an effective artefact reconstruction but most of the times 3D data are not completely and deeply investigated to extract other useful information on historical monuments for their conservation and safeguard. The Cultural Heritage Superintendence of Aosta decided to run a time continual project of monitoring of the Praetorian Roman Gate with the collaboration of the ITABC, CNR of Italy. The Praetorian Roman Gate in Aosta, Italy, of Augustus ages, is one of the most well-known roman monumental gates, it is a double gate with three arches each side, 12 meters high, 20 meters wide, made of pudding stone ashlars, Badoglio, travertine, marble blocks and other stone insertion due to restorations between 1600 and 1950. In years 2000 a final restoration intervention brought the gate at the present state of art, within the frame of a restoration and conservation building site with the purpose of treat the different decay pathologies and conditions. A complete 3D geometric survey campaign has been the first step for the monitoring of the gate morphologic changes and decay progress in time. The main purpose is to collect both quantitative data, related to the geometry of the gate, and the qualitative data, related to the chromatic change on the surface due to the stone decay. The geometric data with colour information permits to associate materials and stone pathologies to chemical or mechanical actions and to understand and analyse superficial decay kinetics. The colours survey will also permit to directly locate on the 3D model areas of different stratigraphic units. The project aims to build a rigorous quantitative-qualitative database so to be uploaded into a GIS. The GIS will become

Radioactivity in fossils at the Hagerman Fossil Beds National Monument.

Farmer, C Neal; Kathren, Ronald L; Christensen, Craig

2008-08-01

Since 1996, higher than background levels of naturally occurring radioactivity have been documented in both fossil and mineral deposits at Hagerman Fossil Beds National Monument in south-central Idaho. Radioactive fossil sites occur primarily within an elevation zone of 900-1000 m above sea level and are most commonly found associated with ancient river channels filled with sand. Fossils found in clay rich deposits do not exhibit discernable levels of radioactivity. Out of 300 randomly selected fossils, approximately three-fourths exhibit detectable levels of natural radioactivity ranging from 1 to 2 orders of magnitude above ambient background levels when surveyed with a portable hand held Geiger-Muller survey instrument. Mineral deposits in geologic strata also show above ambient background levels of radioactivity. Radiochemical lab analysis has documented the presence of numerous natural radioactive isotopes. It is postulated that ancient groundwater transported radioactive elements through sand bodies containing fossils which precipitated out of solution during the fossilization process. The elevated levels of natural radioactivity in fossils may require special precautions to ensure that exposures to personnel from stored or displayed items are kept as low as reasonably achievable (ALARA).

Monumental megalithic burial and rock art tell a new story about the Levant Intermediate Bronze "Dark Ages".

2017-01-01

The Intermediate Bronze Age (IB) in the Southern Levant (ca. 2350-2000 BCE) is known as the "Dark Ages," following the collapse of Early Bronze urban society and predating the establishment of the Middle Bronze cities. The absence of significant settlements and monumental building has led to the reconstruction of IB social organization as that of nomadic, tribal society inhabiting rural villages with no central governmental system. Excavation in the Shamir Dolmen Field (comprising over 400 dolmens) on the western foothills of the Golan Heights was carried out following the discovery of rock art engravings on the ceiling of the central chamber inside one of the largest dolmens ever recorded in the Levant. Excavation of this multi-chambered dolmen, covered by a basalt capstone weighing some 50 tons, revealed a secondary multi-burial (of both adults and children) rarely described in a dolmen context in the Golan. Engraved into the rock ceiling above the multi-burial is a panel of 14 forms composed of a vertical line and downturned arc motif. 3D-scanning by structured-light technology was used to sharpen the forms and revealed the technique employed to create them. Building of the Shamir dolmens required a tremendous amount of labor, architectural mastery, and complex socio-economic organization well beyond the capacity of small, rural nomadic groups. The monumental megalithic burial of the Shamir dolmens indicates a hierarchical, complex, non-urban governmental system. This new evidence supports a growing body of recent criticism stemming from new discoveries and approaches that calls for rethinking our views of the Levantine IB "Dark Ages."

Distribution and abundance of elkhorn coral, Acropora palmata, and prevalence of white-band disease at Buck Island Reef National Monument, St. Croix, US Virgin Islands

In the 1970s and 1980s elkhorn coral, Acropora palmata, declined dramatically throughout the Caribbean primarily due to white-band disease (WBD). In 2005, elkhorn coral was proposed for listing as threatened under the US Endangered Species Act. WBD was first documented at Buck Island Reef National Monument (BIRNM). Together with hurricanes WBD reduced live elkhorn coral coverage by probably over 90%. In the past decade some recovery has been observed at BIRNM. This study assessed the distribution and abundance of elkhorn coral and estimated the prevalence of WBD at the monument. Within an area of 795 ha, we estimated 97,232 134,371 (95% confidence limits) elkhorn coral colonies with any dimension of connected live tissue greater than one meter, about 3% of which were infected by WBD. Despite some recovery, the elkhorn coral density remains low and WBD may continue to present a threat to the elkhorn coral population.

2013-03-01

We process the total-station surveys performed at the ITRF co-location site Medicina (Northern Italy) over the decade (2001-2010) with the purpose of determining the extent of local intrasite motions and relating them to local geophysical processes, the geological setting and the design of the ground pillars. In addition, continuous observations acquired by two co-located GPS stations (MEDI and MSEL separated by ≈27 m) are analysed and their relative motion is cross-checked with the total-station results. The local ground control network extends over a small area (<100 × 100 m) but the results demonstrate significant anisotropic deformations with rates up to 1.6 mm a-1, primarily horizontal, a value comparable to intraplate tectonic deformations. The results derived from GPS and total-station observations are consistent and point to the presence of horizontal intrasite motions over very short distances possibly associated with varying environmental conditions in a very unfavourable local geological setting and unsuitable monument design, these latter being crucial aspects of the realization and maintenance of global permanent geodetic networks and the global terrestrial reference frame.

Water-resources data were acquired during fiscal year 1970 by the U.S. Geological Survey at Dinosaur National Monument, Utah-Colorado, for the U.S. National Park Service as part of a continuing project. The data provide a basis for planning the development, management, and use of the available water resources to provide adequate water supplies. Thirty-one springs, 19 in relatively inaccessible areas, were evaluated as sources of water supplies. Seven potential well sites were evaluated for drilling depths in specific aquifers. A well drilled in Echo Park near the confluence of the Green and Yampa Rivers was tested. The pumping test showed the well to yield 130 gallons per minute with a drawdown of 1.96 feet; specific capacity of the well at 130 gallons per minute is 66 gallons per minute per foot. Water samples for chemical analysis were - collected from nine springs and one well; all except that from Disappointment Spring, were of good chemical quality.

Full Text Available Este artigo examina a política bancária e financeira conduzida por Delfim Netto de 1967 a 1973, a qual se revestiu de características específicas. São examinadas as pronunciadas tendências à concentração no segmento dos bancos comerciais privados e a sua expansão para outras faixas de operação, formando conglomerados financeiros e, assim, alterando profundamente a estrutura projetada originalmente pela reforma de 1964. Ambos os processos estiveram vinculados à orientação particular da política econômica a partir de 1967, cujo sentido maior encontrou expressão na tentativa de implementar, no governo Médici, um projeto de conglomerado integrando banco e indústria, visando a consolidar um segmento de grandes empresas privadas nacionais. O artigo sistematiza evidência disponível acerca desse projeto estratégico - um capítulo importante da política econômica durante uma fase do regime militar.This article discusses the banking policy led by Delfim Netto from 1967 trough 1973, which had special features. It is examined the tendency to banking concentration, very intense in those years, as well as the acute centralization process which led to the constitution of financial conglomerates, thus transforming the financial structure in a way not foreseen by the banking and financial reforms of 1964. Both processes reflected the new course of economic policy since 1967, having as its major objective to induce the formation of a new form of private capitalist organization - the conglomerate, integrating banking and industry -, which would led to the consolidation of a segment of big national private firms. The article seeks to collect the available evidence about that strategic project developed during a phase of the military regime.

first third into the XXth Century. We will be analysing nursing influence in its social context. As well, we will striving to discover its presence in the public/private monuments as social recognition. The aim will be to look at Madrid's female images and select those representing the nursing profession. We chose this chronological frame due to the fact that, on the one hand, nursing as a profession started in the XIXth Century and, on the other one, it was in this same period that this type of monument started to appear in cities. In our research we came across the monument to the Duchess of ‘la Victoria’, its origin, date and artistic style. The Red Cross identified its nurses with it. It illustrated their work with the ‘injured soldiers in the Morocco’s campaign’ and achieved the iconographic analysis of a monument related to nursing care identifying its iconographic theme, historic context and iconological interpretation. Our conclusion is that nurses had little possibility of recognition in the social scheme at the time but, they excelled in their care and professionalism and through this they gained social acknowledgement.

Sulphate neoformation is a major factor of degradation of stone monuments. Boron, sulphur and oxygen isotope signatures were investigated for five French historical monuments (Bourges, Chartres and Marseille cathedrals, Chenonceau castle, and Versailles garden statues) to investigate the role of intrinsic sulphate sources (gypsum plasters and mortars) in stone degradation, compared to the influence of extrinsic sources such as atmospheric pollution. Gypsum plasters and gypsum-containing mortars fall systematically in the δ 34 S and δ 18 O range of Paris Basin Eocene evaporites indicating the origin of the raw materials (so-called 'Paris plaster'). Black crusts show the typical S and O isotope signatures observed elsewhere in Europe that can be attributed to atmospheric pollution, together with a marine component for Marseille. Boron isotopes for black crusts indicate coal combustion as principal boron source. Mortar isotope compositions discriminate three types, one similar to gypsum plasters, one strongly depleted in 34 S, attributed to pyrite oxidation, and a third one close to atmospheric sulphates. The isotopic composition of sulphates and boron of most degraded building stones of the different monuments is well explained by the identified sulphate sources. In several cases (in particular for Chenonceau and Bourges, to some extent for Chartres), the impact of gypsum plaster as building and restoration material on the degradation of the stones in its vicinity was clearly demonstrated. The study illustrates the usefulness of multi-isotope studies to investigate stone degradation factors, as the combination of several isotope systematics increases the discriminatory power of isotope studies with respect to contaminant sources. - Research Highlights: → Insight in stone weathering mechanisms by multi-isotope fingerprinting (B, S, O). → Intrinsic sulphate sources (gypsum plaster, mortar) contribute to stone degradation. → Origin of building materials

The aim of this paper is to identify the different periods of construction or restoration of the lead roof of a historic monument. Trace elements in a lead matrix can be a signature of the metallurgical processes, allowing identification of a specific time period for the production of the lead used to build the roof. The ability of LIBS (Laser Induced Breakdown Spectroscopy) to detect such trace elements in a lead matrix is therefore explored and checked by comparing its results with LA-ICP-MS as a reference method (Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry). Concentrations of 263 samples were compared between LIBS and LA-ICP-MS data and their correlation was evaluated. Another way to compare their results is also suggested by combining PCA (Principal Component Analysis) and GIS (Geographic Information System). As a result statistical mappings were created, highlighting metallurgical groups of samples across the roof of the building. This innovative approach links concentration and spatial location resulting in an easily interpretable graphical presentation of the data. The results of both spectrometry methods lead to similar conclusions with distinctive areas of different lead compositions and by extension different lead dating across the roof. But since LIBS is portable we can conclude that it is a suitable and reliable instrument for in-situ applications on historic monuments. - Highlights: • Quantification of trace elements (Ag, Bi, Cu and Sn) in a lead matrix by LIBS and LA-ICP-MS • Low limit of detection for Ag, Bi, Cu and Sn by using LIBS portable instrumentation • Set up a specific data processing combining PCA and GIS for cultural heritage application • Comparison of LIBS and LA-ICP-MS results with 263 samples • 488 samples analyzed by LIBS.

Monumental megalithic burial and rock art tell a new story about the Levant Intermediate Bronze "Dark Ages".

Directory of Open Access Journals (Sweden)

Gonen Sharon

Full Text Available The Intermediate Bronze Age (IB in the Southern Levant (ca. 2350-2000 BCE is known as the "Dark Ages," following the collapse of Early Bronze urban society and predating the establishment of the Middle Bronze cities. The absence of significant settlements and monumental building has led to the reconstruction of IB social organization as that of nomadic, tribal society inhabiting rural villages with no central governmental system. Excavation in the Shamir Dolmen Field (comprising over 400 dolmens on the western foothills of the Golan Heights was carried out following the discovery of rock art engravings on the ceiling of the central chamber inside one of the largest dolmens ever recorded in the Levant. Excavation of this multi-chambered dolmen, covered by a basalt capstone weighing some 50 tons, revealed a secondary multi-burial (of both adults and children rarely described in a dolmen context in the Golan. Engraved into the rock ceiling above the multi-burial is a panel of 14 forms composed of a vertical line and downturned arc motif. 3D-scanning by structured-light technology was used to sharpen the forms and revealed the technique employed to create them. Building of the Shamir dolmens required a tremendous amount of labor, architectural mastery, and complex socio-economic organization well beyond the capacity of small, rural nomadic groups. The monumental megalithic burial of the Shamir dolmens indicates a hierarchical, complex, non-urban governmental system. This new evidence supports a growing body of recent criticism stemming from new discoveries and approaches that calls for rethinking our views of the Levantine IB "Dark Ages."

This study aimed to evaluate the action of organic acids produced by the fungal population associated with the biodeterioration process of the Twelve Prophets of Aleijadinho, a set of soapstone sculptures in Congonhas, state of Minas Gerais, Brazil. For this, samples of fungi were obtained from the surface of each of the 12 outdoor stone sculptures that comprise the set of Prophets. The identification of the colonizing filamentous fungi was performed by classical microbiology and molecular methods. Some species of filamentous fungi-dependent cultivation were detected, and the presence of species Aspergillus versicolor, Curvularia lunata, Epicoccum nigrum, Penicillium citrinum and Pseudocercospora norchiensis indicated a connection with the excretion of organic acids. The acids produced by each of these fungal species were analysed quantitatively by chromatographic methods, revealing potential biodeterioration by the action of acidic metabolites excreted in the stone. Minas Gerais, Brazil, is vulnerable to the activities of mineral extraction industries, posing an imminent risk to United Nations Educational, Scientific and Cultural Organization (UNESCO) recognized cities, e.g. Congonhas. Many of these municipalities hold many soapstone religious sculptures and historical monuments. Consequently, soapstone is susceptible to filamentous fungi attack causing irreversible biodeterioration. Despite the concern related to nondestructive sampling of 18th century sculptures, in this study, we have discussed the factors that lead to biodeterioration of soapstone due to organic acid excretion by the fungi that damage the stone, thereby providing an insight in conserving and preserving the soapstone monuments. © 2017 The Society for Applied Microbiology.

In this work we describe the deformation mechanisms and processes that occurred during the evolution of cataclastic deformation bands developed in the feldspar-rich conglomerates of the Rio do Peixe Basin, NE Brazil. We studied bands with different deformation intensities, ranging from single cm-thick tabular bands to more evolved clustering zones. The chemical identification of cataclastic material within deformation bands was performed using compositional mapping in SEM images, EDX and XRD analyses. Deformation processes were identified by microstructural analysis and by the quantification of comminution intensity, performed using digital image processing. The deformation bands are internally non homogeneous and developed during five evolutionary stages: (1) moderate grain size reduction, grain rotation and grain border comminution; (2) intense grain size reduction with preferential feldspar fragmentation; (3) formation of subparallel C-type slip zones; (4) formation of S-type structures, generating S-C-like fabric; and (5) formation of C‧-type slip zones, generating well-developed foliation that resembles S-C-C‧-type structures in a ductile environment. Such deformation fabric is mostly imparted by the preferential alignment of intensely comminuted feldspar fragments along thin slip zones developed within deformation bands. These processes were purely mechanical (i.e., grain crushing and reorientation). No clays or fluids were involved in such processes.

Székesfehérvár is a city in central Hungary, located around 65 km southwest of Budapest. In the Middle Ages (11th and 12th centuries), the city was a Royal residence and until the Turkish occupation in 1543, one of the most important cities of Hungary. The Ruin Garden of Székesfehérvár is a unique assemblage of monuments belonging to the cultural heritage of Hungary due to its important role in the Middle Ages as the coronation church for the kings of the Hungarian Christian Kingdom and the burial place for fifteen kings and other members of the royal families and the high nobility. It was also the home of the royal treasury and relics. It is comprised of a provostal church dedicated to Virgin Mary, so called today "Royal Basilica", royal tombs and related ecclesial and lay buildings. Since it has been nominated for "National Memorial Place", its present and future protection is required. Its several reconstructions and expansions throughout Hungarian history introduce another aspect of the importance of the historical site. By a quick overview of the current state of the monument, the presence of several lithotypes could be found among the remained building and decorative stones. Therefore, the research related to the materials in order to understand their composition, structure, origin and behavior was crucial not only for the conservation of that specific monument but also for a series of other historic structures in the Hungarian territory. In order to help the study of the Ruin Garden in Székesfehérvár, a series of maps was created based on in-situ investigations. Five wall sections were selected for the sake of the different lithotypes distribution and the different construction periods were the ruins belong to. The total mapped area covers about 30 m2 of the existing walls surfaces. Three different kinds of maps were designed for each wall section. The first series of maps depicts the different construction periods of the selected section of the

Mountains, Monuments, and other Matter: Environmental Affects at Manzanar

Full Text Available This essay investigates the natural landscapes and built structures at the Manzanar National Historic Site, the first of ten incarceration camps to open in 1941 and a temporary home for over 11,000 Japanese Americans. Using former incarceree Jeanne Wakatsuki Houston’s writing as a touchstone, my essay foregrounds the environmental features of the (relocation: the extreme desert weather, the mountain vistas, the incarceree-created rock gardens, the reconstructed barracks, guard tower, and barbed wire fence, and the cemetery/monument. I bring together concepts from ecocriticism and from affect theory—particularly Ben Anderson’s “affective atmospheres,” Sianne Ngai’s “tone,” and Sara Ahmed’s characterization of affect as “sticky”—and develop the notion of affective agency to describe the impacts generated by environments and objects at this national memory site. I assess how the visual and written rhetoric at the site addresses what I call an implied tourist, and I show how powerful emotions of shame, anger, grief, and compassion—and sometimes, mixed, even contradictory, affects—are not only represented in visual and written rhetoric but are also, in a sense, communicated by the environment itself. More broadly, I suggest that ecocritical theory brings a useful lens to discussions of public memory, and that affect theory helps account for the less tangible, visceral, experiences visitors have at Manzanar and other fraught historical sites, as well as within our everyday environments.

Granite-rapakivi was widely used in the architecture of St. Petersburg: the facades of buildings, embankments of rivers and canals, bridges, sculptural monuments, pedestals, facing the metro stations. This stone is rapidly destroyed due to the peculiarities of its structure. Biofouling of granite is insufficiently studied. Cause the destruction of granite can be bacteria, microscopic algae, fungi, mosses, lichens, higher plants, invertebrates and vertebrates. They often form specific lithobiotic communities that contribute to the destruction of granite-rapakivi. The objects of research were monuments of St. Petersburg (granite sculpture, facades, facing embankments) as well as granite-rapakivi quarries in Russia and Finland, where the stone was quarried for use in St. Petersburg. Sampling was carried out from the most typical biofouling sites. Different methods were applied for the study of damaged granite: petrographic analysis, light and scanning electron microscopy, methods for detection and identification of microorganisms, X-ray microprobe analysis. As result the main forms of granite destruction were described: fractures, ovoid weathering, granular disintegration, surface films, crusts and layers, pitting and fouling. Lichens, mosses, herbaceous and micromycetes were dominated on the granite-rapakivi in quarries. For example, in a Monferran quarry (Virolahti region) the complicated lithobiotic community was revealed. It included 30 species of micromycetes, 31 species of lichens, 10 species of moss. Bacteriological analysis showed the dominance of bacteria Bacillus, and actinomycetes in microbial biofilms. More than 100 species of plants were found on the granite embankments in St. Petersburg. They were confined to the cracks, seams of granite blocks. Plants and mosses were common to the granite embankments of rivers and canals in the central (historical) part of the city. Dimensions of mosses depend on the area of the deepening which they occupy. The most

The problem of mechanical compatibility of natural building stones in restoration of monuments. Part I: Composite specimens

Kourkoulis, Stavros K.; Ninis, Nikolaos L.

2011-12-01

The mechanical compatibility of natural building stones used in the restoration of ancient monuments as substitutes of the authentic material is studied in this short two-paper series. Attention is focused on the porous oolitic limestone of Kenchreae used in the erection of the monuments at the Epidaurean Asklepieion. In Part I experimental results are presented concerning the mechanical properties and constants of both the authentic (ancient and freshly quarried) material and the various stones proposed so far as possible substitutes. It is concluded that only the Kenchreae stone satisfactorily simulates the behaviour of the material used by ancient Greeks. The other types of stones have a substantially different character and their incorporation in the restoration should be treated with caution. In an effort to quantify the influence of the substitute stone on the authentic one, a series of experiments were carried out using composite specimens made from equal parts of authentic and substitute material with various inclination angles of the adhesion plane with respect to the load. It was concluded that the mechanical properties of the composite specimen are strongly affected by this angle and the dependence is not monotonous. In addition, strong strain discontinuities are recorded in the vicinity of the adhesion plane, which are responsible for the initiation of cracking in either of the two materials. It was pointed out that in some cases the incompatibility causes violation of the basic restoration principle concerning the protection of the ancient material. In this context certain geometrical configurations of the boundaries of the specimens are examined in Part II as a possible means of modifying the mechanical behaviour of the substitute stones, in order to make them as compatible as possible with the authentic material.

Monumental megalithic burial and rock art tell a new story about the Levant Intermediate Bronze “Dark Ages”

The Intermediate Bronze Age (IB) in the Southern Levant (ca. 2350–2000 BCE) is known as the “Dark Ages,” following the collapse of Early Bronze urban society and predating the establishment of the Middle Bronze cities. The absence of significant settlements and monumental building has led to the reconstruction of IB social organization as that of nomadic, tribal society inhabiting rural villages with no central governmental system. Excavation in the Shamir Dolmen Field (comprising over 400 dolmens) on the western foothills of the Golan Heights was carried out following the discovery of rock art engravings on the ceiling of the central chamber inside one of the largest dolmens ever recorded in the Levant. Excavation of this multi-chambered dolmen, covered by a basalt capstone weighing some 50 tons, revealed a secondary multi-burial (of both adults and children) rarely described in a dolmen context in the Golan. Engraved into the rock ceiling above the multi-burial is a panel of 14 forms composed of a vertical line and downturned arc motif. 3D-scanning by structured-light technology was used to sharpen the forms and revealed the technique employed to create them. Building of the Shamir dolmens required a tremendous amount of labor, architectural mastery, and complex socio-economic organization well beyond the capacity of small, rural nomadic groups. The monumental megalithic burial of the Shamir dolmens indicates a hierarchical, complex, non-urban governmental system. This new evidence supports a growing body of recent criticism stemming from new discoveries and approaches that calls for rethinking our views of the Levantine IB “Dark Ages.” PMID:28253312

The role of monumental trees for the preservation of saproxylic biodiversity: re-thinking their management in cultural landscapes

Directory of Open Access Journals (Sweden)

2017-07-01

Full Text Available Ancient trees present structural and functional characteristics fundamental for sustaining complex and unique assemblages of species. They are a resource globally threatened by both intensive land uses and lack of recruitment. Their disappearance would involve not only the loss of majestic organisms with high intrinsic value, but may also result in the disappearance of rare and endangered species. Italy is currently implementing a new list of noteworthy ancient trees (i.e. monumental trees and the preliminary results of this new inventory have been analysed as a case study of a national initiative. The provisional list included 950 complete records, corresponding to 65 genera and 118 species. The most abundant species was Quercus pubescens Willd while the most common genera were Quercus, Larix, Cedrus, Fagus and Platanus. Age and size were the most used criteria for inclusion of trees in the census. The fundamental novelty of the new inventory is that it is based on a set of well-defined criteria of monumentality and that it clearly recognised the ecological value of ancient trees. Preserving a tree for its ecological role requires a profound cultural shift. The value of microhabitats, structures that have historically been considered defects, should be recognised and managed accordingly. Ancient trees are often part of disappearing cultural landscapes: to preserve the richness and diversity of these habitats, new policies and regulations are needed. The preservation of landscapes, where there is still a high density of ancient trees, should be a priority for all European countries in order to conserve their unique associated fauna and for their irreplaceable functional value for biodiversity conservation.

Data of a magnetic susceptibility of ferro-and the ferrimagnetic particles of many technogenic, natural, special media are especially demanded for the solution of various tasks connected with purposeful magnetic impact on these particles. One of productive approaches to definition of a magnetic susceptibility χ of these particles consists in receiving experimental data of a susceptibility of disperse samples 〈 χ 〉 with a disperse phase of these particles. The paper expounds and analyses the results of experiments on defining (by Faraday method in a magnetic field with intensity H = 90-730 kA/m) the magnetic susceptibility 〈 χ 〉 of disperse samples (conglomerates) with a given volume ratio γ of magnetite particles (γ = 0.0065-0.25). The corresponding families of concentration and field dependences are provided alongside with discussing the applicability of linear and exponential functions to describe these dependences. We consider the possibility of defining single particles susceptibility χ (with simultaneous obtaining field dependence of this susceptibility) by the commonly used relation χ = 〈 χ 〉 /γ both at relatively small (preferable for accuracy reasons) values γ - to γ = 0.02…0.025, as well as at increased values γ - up to γ = 0.25. The data χ are provided depending on H and correlating with known data at H matter magnetic susceptibility χm (for the case when the particles are traditionally likened to balls with the characteristic for them demagnetising factor equalling 1/3) complies with the anticipated inverse function χm ∼ 1/H in the studied area H (where magnetization M expressed as M = χH reaches saturation M = Const).

Geologic storage of carbon dioxide (CO 2 ) is considered a viable strategy for significantly reducing anthropogenic CO 2 emissions into the atmosphere; however, understanding the flow mechanisms in various geological formations is essential for safe storage using this technique. This study presents, for the first time, a two-phase (CO 2 and brine) flow visualization under reservoir conditions (10 MPa, 50 °C) for a highly heterogeneous conglomerate core obtained from a real CO 2 storage site. Rock heterogeneity and the porosity variation characteristics were evaluated using X-ray computed tomography (CT). Multiphase flow tests with an in-situ imaging technology revealed three distinct CO 2 saturation distributions (from homogeneous to non-uniform) dependent on compositional complexity. Dense discontinuity networks within clasts provided well-connected pathways for CO 2 flow, potentially helping to reduce overpressure. Two flow tests, one under capillary-dominated conditions and the other in a transition regime between the capillary and viscous limits, indicated that greater injection rates (potential causes of reservoir overpressure) could be significantly reduced without substantially altering the total stored CO 2 mass. Finally, the capillary storage capacity of the reservoir was calculated. Capacity ranged between 0.5 and 4.5%, depending on the initial CO 2 saturation.

The Kelton Pass SE and Monument Peak SW 7.5' quadrangles are located in Box Elder County, northwestern Utah (figure 1; plate 1). The northern boundary of the map area is 8.5 miles (13.7 km) south of the Utah-Idaho border, and the southern boundary reaches the edge of mud flats at the north end of Great Salt Lake. Elevations range from 4218 feet (1286 m) along the mud flats to 5078 feet (1548 m) in the Wildcat Hills. Deep Creek forms a prominent drainage between the Wildcat Hills and Cedar Hill. The closest towns are the ranching communities of Snowville, Utah (10 miles [16 km] to the northeast) (figure 1), and Park Valley, Utah (10 miles [16 km] to the west).The Kelton Pass SE and Monument Peak SW 7.5' quadrangles are located entirely within southern Curlew Valley, which drains south into Great Salt Lake, and extends north of the area shown on figure 1 into Idaho. Curlew Valley is bounded on the west by the Raft River Mountains and on the east by the Hansel Mountains (figure 1). Sedimentary and volcanic bedrock exposures within the quadrangles form the Wildcat Hills, Cedar Hill, and informally named Middle Shield (figure 1). Exposed rocks and deposits are Permian to Holocene in age, and include the Permian quartz sandstone and orthoquartzite of the Oquirrh Formation (Pos), tuffaceous sedimentary rocks of the Miocene Salt Lake Formation (Ts), Pliocene basaltic lava flows (Tb) and dacite (Tdw), Pleistocene rhyolite (Qrw) and basalt (Qb), and Pleistocene and Holocene surficial deposits of alluvial, lacustrine, and eolian origin. Structurally, the map area is situated in the northeastern Basin and Range Province, and is inferred to lie within the hanging wall of the late Miocene detachment faults exposed in the Raft River Mountains to the northwest (e.g., Wells, 1992, 2009; figure 1).This mapping project was undertaken to produce a comprehensive, large-scale geologic map of the Wildcat Hills, as well as to improve understanding of the volcanic and tectonic evolution of

A new approach to assess the chemical composition of powder deposits damaging the stone surfaces of historical monuments.

Science.gov (United States)

Fermo, Paola; Turrion, Raquel Gonzalez; Rosa, Mario; Omegna, Alessandra

The issue of conservation of the monumental heritage worldwide is mainly related to atmospheric pollution that causes the degradation of stone surfaces. The powder deposits present on the stone monuments reflect the composition of the aerosol particulate matter (PM) to which the surfaces are exposed, so the chemical characterization of the outermost damaged layers is necessary in order to adopt mitigation measurements to reduce PM emissions. In the present paper, a new analytical approach is proposed to investigate the chemical composition of powder deposits present on Angera stone, a dolomitic rock used in the Richini courtyard, a masterpiece of Lombard Baroque and placed in Milan. Inorganic and organic components present in these deposits have been analyzed by IC (ion chromatography) and a new approach mainly bases on thermal analyses, respectively. Gypsum is the main inorganic constituent indicating a composition similar to that of black crusts, hard black patina covering the degraded building surfaces. Ammonium nitrate present in the powder is able to react with the stone substrate to form magnesium nitrate which can migrate into the porous stone. The carbonaceous fraction powder deposits (i.e. OC = Organic Carbon and EC = Elemental Carbon) have been quantified by a new simple thermal approach based on carbon hydrogen nitrogen (CHN) analysis. The presence of high concentration of EC confirms that the powder deposits are evolving to black crust. Low values of water-soluble organic carbon (WSOC, determined by total organic carbon-TOC), with respect to what is normally found in PM, may indicate a migration process of organic substances into the stone with a worsening of the conservation conditions. The presence of heavy metals of anthropogenic origin and acting as catalysts in the black crust formation process has been highlighted by SEM-EDS (electron microscopy coupled with an energy dispersive spectrometer) as well.

Baseline risk assessment for groundwater contamination at the uranium mill tailings site near Monument Valley, Arizona. Draft

Energy Technology Data Exchange (ETDEWEB)

1993-09-01

This baseline risk assessment evaluates potential impact to public health or the environment resulting from groundwater contamination at the former uranium mill processing site near Monument Valley, Arizona. The tailings and other contaminated material at this site are being relocated and stabilized in a disposal cell at Mexican Hat, Utah, through the US Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project. The tailings removal is planned for completion by spring 1994. After the tailings are removed, groundwater contamination at the site will continue to be evaluated. This risk assessment is the first document specific to this site for the Groundwater Project. It will be used to assist in determining what remedial action is needed for contaminated groundwater at the site.

Art and politics in the former "Portuguese Colonial Empire". The monument to Mouzinho de Albuquerque in Lourenço Marques

Verheij, Gerbert

2013-01-01

Full Text Available In 1940, a monument to Mouzinho de Albuquerque is inaugurated in the former capital of the Portuguese Colony of Mozambique, Lourenço Marques. The result of a lenghty commissioning process, this homage to one of the main heroes of the colonial pantheon becomes a center-piece in the many political rituals which had become common-place during the 1930s. The concepts of aura and cult value are used to analyse its "traditionalist" aesthetics and the role it played in political spectacles, arguing that it obeys a strategy of representation of the public space as "Empire".

Quartz-pebble-conglomerate gold deposits: Chapter P in Mineral deposit models for resource assessment

Science.gov (United States)

Taylor, Ryan D.; Anderson, Eric D.

2018-05-17

Quartz-pebble-conglomerate gold deposits represent the largest repository of gold on Earth, largely due to the deposits of the Witwatersrand Basin, which account for nearly 40 percent of the total gold produced throughout Earth’s history. This deposit type has had a controversial history in regards to genetic models. However, most researchers conclude that they are paleoplacer deposits that have been modified by metamorphism and hydrothermal fluid flow subsequent to initial sedimentation.The deposits are found exclusively within fault-bounded depositional basins. The periphery of these basins commonly consists of granite-greenstone terranes, classic hosts for lode gold that source the detrital material infilling the basin. The gold reefs are typically located along unconformities or, less commonly, at the top of sedimentary beds. Large quartz pebbles and heavy-mineral concentrates are found associated with the gold. Deposits that formed prior to the Great Oxidation Event (circa 2.4 giga-annum [Ga]) contain pyrite, whereas younger deposits contain iron oxides. Uranium minerals and hydrocarbons are also notable features of some deposits.Much of the gold in these types of deposits forms crystalline features that are the product of local remobilization. However, some gold grains preserve textures that are undoubtedly of detrital origin. Other heavy minerals, such as pyrite, contain growth banding that is truncated along broken margins, which indicates that they were transported into place as opposed to forming by in situ growth in a hydrothermal setting.The ore tailings associated with these deposits commonly contain uranium-rich minerals and sulfides. Oxidation of the sulfides releases sulfuric acid and mobilizes various metals into the environment. The neutralizing potential of the tailings is minimal, since carbonate minerals are rare. The continuity of the tabular ore bodies, such as those of the Witwatersrand Basin, has allowed these mines to be the deepest in

Stratigraphy and structure of the Miners Mountain area, Wayne County, Utah

Science.gov (United States)

Luedke, Robert G.

1953-01-01

The Miners Mountain area includes about 85 square miles in Wayne County, south-central Utah. The area is semiarid and characterized by cliffs and deep canyons. Formations range in age from Permian to Upper Jurassic and have an aggregate thickness of about 3,500 feet. Permian formations are the buff Coconino sandstone and the overlying white, limy, shert-containing Kaibab limestone. Unconformably overlying the Kaihab is the lower Triassic Moenkopi formation of reddish-brown and yellow mudstone, siltstone, and sandstone; it contains the Sinbad limestone member (?) in the lower part. Thin, lenticular Shinarump conglomerate unconformably overlies the Moenkopi, but grades upward into the Upper Triassic Chinle formation of variegated mudstone with some interbedded sandstone and limestone lenses. Uncomformably overlying the Chinle are the Wingate sandstone, Kayenta formation, and Navajo sandstone of the Jurassic (?) Glen Canyon group, which consist of red to white sandstone. Only the lower part of the Carmel formation of the Upper Jurassic San Rafael group is exposed in the area; it consists of variegated siltstone, sandstone, limestone, and gypsum. The conspicuous structural feature in the area is the Teasdale anticline which trends northwest, is about 14 miles long, and is asymmetric with a steeper west flank. Bounding the anticline on the northeast and east is the Capitol Reef monocline, the northern part of the Waterpocket Fold. Strata in the area are broken by steeply-dipping normal faults with small displacements, except for the Teasdale fault which has a maximum displacement of over 1,000 feet. Jointing is prominent in some formations. The major orogenic movement in the area is believed to be late Upper Cretaceous to early Tertiary. Epeirogenic uplift occurred intermittently throughout Tertiary and perhaps Quaternary time.

Historic monuments and buildings are critical cultural assets which cannot be presented by again by human beings. Longer affected by natural climate, environment and biological behavior (including human), resulting in damage and the need for repair. Therefore, UNESCO proposed periodic reporting and reactive monitoring in 2007, in order to achieve "early detection, early repair". This study discusses about suitable preservation monitoring methods for Taiwan. To shed light on damage and impact factors of historical buildings and cultural relics, the study is based on impact and sensor, monitoring method, monitoring period and maintenance personnel in order to propose standard operating procedures of monitoring method. To reduce the rate of the human and sensor monitoring, with the long-term monitoring data analysis, it is calculated that 30 minutes is the best period of data collecting. Besides, the study is adopted regression analysis to select temperature variable only then calculate humidity variable function. This study provides a reference monitoring method for monitoring personnel and maintenance personnel, and establishes a long-term monitoring data based information for damage and destroy in the future. Monitoring period and maintenance personnel can follow the data based to find out the damage points and problems, to keep the value of cultural assets.

Controls on dripwater chemistry of Oregon Caves National Monument, northwestern United States

Science.gov (United States)

Rushdi, Ahmed I.; Ersek, Vasile; Mix, Alan C.; Clark, Peter U.

2018-02-01

Cave dripwater chemistry of Oregon Caves National Monument (OCNM) was studied, where the parameters pH, total alkalinity, calcium, magnesium, strontium, sodium and barium were analyzed at quasi-monthly intervals from 2005 to 2007. Different statistical analyses have been used to investigate the variability of the chemical parameters in the different sites in the OCNM cave system. The dripwater varies in response to seasonal changes in rainfall. The drip rates range from zero in summer to continuous flow in winter, closely following the rainfall intensity. Spatial variations of dripwater chemistry, which is nonlinearly related to dripwater discharge likely, reflect the chemical composition of bedrock and overlying soil, and the residence time of the ground water within the aquifer. The residence time of infiltrated water in bedrock cracks control the dissolution carbonate bedrock, reprecipitation of calcium carbonate and the degree of saturation of dripwater with respect to calcium carbonate minerals. Spatiotemporal fluctuations of dripwater Mg/Ca and Sr/Ca ratios are controlled by dissolution of carbonate bedrock and the degree of calcite reprecipitation in bedrock cracks. This suggests that trace elements in speleothem deposits at the OCNM may serve as paleoclimatological proxies for precipitation, if interpreted within the context of understanding local bedrock chemistry.

2010-02-01

The research was based primarily on data collected in the process of work, existing file. The journals have been the prime source to describe the construction of the Monumental Fountain. However, given the political context of the time, the journals say little about the logic that led to the belated realization of the work, since their concern is, above all, credibility and consolidate the political image of the regime. In this study, the consultation of journals made by the need to contextualize the motivations of political and ideological order that accompanied the launching of the construction. In the absence of justification on the grounds that caused the delay in the work, we used to see the file's administrative order. This made it possible to obtain unpublished data on the construction of commemorative works such as launching an international tender for electrical installation and plumbing of water games or contingencies that led to the tardy commencement of the works and the replacement of material originally intended for artistic commissions.

The Otolith Group’s “Monuments to Dead Television.” Independent Cinema and the Migrant Experience in Europe between Television and the Museum

Directory of Open Access Journals (Sweden)

Beatrice Ferrara

2014-04-01

Full Text Available “Monument to dead television” is the expression the British collective The Otolith Group uses to define its activity of recuperating long-lost quality films, and re-screening them in contemporary art museums and gallery spaces. What these films share is a cinematic vocation and a complex approach to the question of memory and migration in Europe, and to the role of images as testimonies or documents. This essay explores The Otolith Group’s interest in such forgotten archives of modern television in order to unearth their significance for contemporary museums today.

Utilizing remote sensing to supplement ground monitoring of Diorhabda elongata as a control agent for Tamarix ramosissima in Dinosaur National Monument

Science.gov (United States)

Archambault, V.; Auch, J.; Landy, J.; Rudy, G.; Seifert, C.; Schmidt, C.; Skiles, J.

2008-12-01

The plant Tamarix ramosissima has invaded significant riparian habitat along the Green River in Dinosaur National Monument. Commonly known as salt cedar or tamarisk, it was introduced from Eurasia to the Southwestern United States to prevent soil erosion along riverbanks and as an ornamental plant. It has since come to affect water resources, recreation, wildlife, and ecosystem services. Various methods used to control tamarisk's spread have had moderate success but have drained National Park Service of human and monetary resources. In June 2006, the salt cedar leaf beetle (Diorhabda elongata) was released as a biological control agent within the park to defoliate and ultimately eradicate the invasive species. This study examines the efficacy of using Landsat TM imagery to supplement ground monitoring of the beetle's spread and its effects on tamarisk in Dinosaur National Monument, and discusses the development of a GIS model to predict annual change in tamarisk cover and beetle populations. Through fieldwork, we determined four areas of interest with favorable attributes for satellite detection. A change detection model was created by layering 2005-2008 data and quantifying mean NDVI. Results show that intra-year NDVI trends may be more effective for accurate detection than single-image year-to-year comparisons largely because intra-year environmental variability is significantly smaller. Additionally, our GIS model predicted significant growth of beetle population, implying that defoliation will become more apparent in future years. However, challenges to detecting this defoliation include the year-to-year variability of environmental factors, low spatial resolution of Landsat TM data, low visibility into parts of the Green River canyon, and the spectral mixing of tamarisk and native vegetation.

Full Text Available Microcolonial black fungi have their natural ecological niche on rocks and walls of hypogean environments, playing an important role in the deterioration of materials and aesthetical alteration of monumental stones and mortars. Three black fungi (Sarcinomyces sp., Pithomyces sp. and Scolecobasidium sp. have been isolated from cultural assets of historical interest. These fungal strains have been used to test the microwave heating method as a new control methodology for eradicating the fungal biological growth on cultural stone artifacts. This methodology is based on a 2.45 GHz microwave electromagnetic radiation, generated by a new apparatus with an appropriate applicator. The first results showed the best dose of 65°C for three minutes, for all the investigated fungal strains. This methodology is very promising because is safety for the operator and the environment, and can be easily applied on site. The use of this method to kill biodeteriogens can avoid the application of chemicals formulates potentially dangerous for substrates and environment.

Railway network in Turkey dates back to more than a hundred years ago and according to official records, there are approximately 18,000 railway bridges with spans varying between 50 cm up to 150 meters. One of them is a monumental concrete arch bridge with a total length of 210 meters having three major spans of 30 meters and a height of 65 meters, located in an earthquake-prone region in southern part of the country. Three-dimensional finite element model of the bridge was generated using a commercially available general finite element analysis software and based on the outcomes of a series of in-depth acceleration measurements that were conducted on-site, the model was refined. Types of ground motion records were used to investigate the seismic response and vulnerability of this massive structure in order to provide information regarding (i) damage-susceptible regions of the structure for monitoring purposes, and, (ii) seismic loads to be taken into account during evaluation and possible strengthening phases for this type of structures.

2010-05-01

Los Morteros (8˚39'54″S, 78˚42 '00″W) is located in coastal, northern Peru, one of the six original centers of world civilization. The site consists of a large, sand-covered, isolated prominence situated on a Mid-Holocene shoreline, ˜ 5 km from the present coast. Preceramic archaeological deposits (4040 ± 75 to 4656 ± 60 14C yr BP or ˜ 3600-5500 cal yr BP) cap this feature, which has been identified by prior researchers as a sand-draped, bedrock-cored landform or a relict dune deposit. Because neither explanation is geomorphologically probable, we used ground-penetrating radar (GPR) and high-resolution mapping to assess the mound's interior structure. Our results indicate an anthropogenic origin for Los Morteros, potentially placing it among the earliest monumental structures in prehistoric South America. The extremely arid setting raises new questions about the purpose and the logistics of early mound construction in this region. This work demonstrates the value of an integrated Quaternary sciences approach to assess long-term landscape change and to understand the interaction between humans and the environment.

The Espinhaco Range in the Grao Mogol region, center-north of Minas Gerais state, is composed by fine grained quartzites with large cross stratifications (Resplandescente Formation), which are covered with erosional unconformity by monomictic conglomerates, and medium to coarse grained quartzites (Grao Mogol Formation), both units belonging to the Espinhaco Supergroup, of Proterozoic age. At the locality known as 'Pedra Rica' (signify Rich Rock, an old diamond digging), rocks of these formations were sampled and separated detrital zircons to acquire U-Pb by Laser Ablation Inductively LA-ICPMS) ages. The analyzed grains are rounded to slightly rounded and show oscillatory zoning. The obtained results indicate a maximum depositional age of 1,595±20 Ma for the Resplandescente Formation, and 1,052±50 Ma for the Grao Mogol Formation. The comparison between the obtained data and the available ages for the Diamantina region and proximities, in the same diamond province, indicates a strong evidence for the existence of at least two primary mineralizing events in the basin, in the age range of 1.35 to 1.05 Ga.

Eastern Traditions and Innovations in Sarmatian Monuments of Second Half of the 2nd – 4th cc. AD

Directory of Open Access Journals (Sweden)

2017-10-01

Full Text Available The appearance of the monuments of the late Sarmatian culture has been recorded since the middle of the 2nd century AD on a vast territory from the Southern Urals to the Lower Don. The new culture is characterized by its own characteristics that distinguish it from the previous culture. This is the northern orientation of the buried, narrow pits and graves, artificial deformation of skulls, square censers, long stalks, mirrors with a central loop, stone tops and staples of swords. In different regions the formation of culture is characterized by specific features. In the Southern Urals, the late Sarmatian culture is represented in the purest form. In the Lower Volga region, a complex is formed, in which the signs of both late Sarmatian and Middle Sarmatian cultures are combined. This is due to the large number of the previous population which remained here. In the Lower Don region, there is a rapid change of cultures. The given article attempts to determine the area of distribution of elements of the late Sarmatian culture and the degree of their influence in different regions. The analysis shows that as for second half of the 2nd –first half of the 3rd century AD, we can talk about a unified late Sarmatian culture from the Trans-Ural to the Lower Don. Some features of the late Sarmatian culture are revealed in the Northern Black Sea region, but they are disjointed and not dominant. This does not allow to include the Northern Black Sea Coast in the area of distribution of the late Sarmatian culture. Finds of eastern origin in the late Sarmatian monuments indicate the absence of stable trade and economicties with the territories of Middle and Central Asia. The occurrence of such things was of an accidental nature, and they were distributed together with their owners. At present, there is no reason to talk about the possible functioning of the northern branch of the Silk Road through the steppes of the Ural-Don region in the late Sarmatian

Erosion caused by external factors such as wind, rain, sunlight and temperature changes is considerable in raw materials used to build pre-hispanic monuments. However, there does exist an internal destruction factor even stronger: the humidity coming from the soil, which goes up by capillarity, depositing soluble salts on the walls surface. Therefore, one way to find some figure related to the specific capillarity or porosity shown by each raw material, is to obtain small prism-shaped pieces cut out from the large debris fallen down spontaneously from ancient walls due to internal humidity. Once these small samples are placed in contact with a 22 Na labeled solution during a given time, at the same geometrical conditions, dried overnight, conditioned either in test tubes or wrapped into polyethylene and detected in a well type 3' x 3' scintillation detector, the counts accumulated per time and weight units are a measure of the relative porosity shown by each material. In order to pull down this porosity, the samples are impregnated with a gelatin solution (50 g/l) at 60-80 deg C plus food preservatives such as potassium sorbate (2.5%) and sodium benzoate (2.5%). When gelatin begins to be formed 3 hours later and the samples look humid and brilliant, they are impregnated with formaldehyde solution (38%), and their absorption rate is dramatically reduced overnight (75-100%), which can be proven when samples are tested by making use of the 22 Na labeled solution. This technique has been applied at real scale in some pre-hispanic monuments. Ancient raw materials seems to be much more compact and well preserved during one limited period of time (10 to 13 months). Treatment is unnoticeable and reversible, and it may be applied periodically. (author)

SHM experiences of monuments in different structural use and environmental conditions

In the last decades the need for an effective seismic protection and vulnerability reduction of strategic structures and particularly the architectural heritage determined a growing interest in Structural Health Monitoring (SHM) as measure of passive mitigation of earthquake effects. The object of monitoring is to identify, locate and classify type and severity of damage induced by external actions or degradation phenomena and to assess their effects on the structural performance. In this way it is possible to take appropriate measures to reduce the danger of collapse and, when necessary, perform straightening interventions to improve the structural and seismic capacity. Motivated by the above reasons, the paper provide a contribution to the application of integrated methodologies and techniques, based on SHM, for the assessment and protection of Cultural Heritage (CH) buildings and monuments. Selected case studies, equipped with distributed sensors and acquisition systems. allowed the definition and successive validation of SHM as a knowledge-based assessment tool, implemented to evaluate intervention needs, following an incremental approach during their execution, and to control the damage states of buildings in a post-seismic scenario. In order to maximize the benefits of SHM and optimize the entire process, dedicated software for static monitoring and automated algorithms for modal parameters identification have been developed, able to provide almost real time information on the health state of the monitored structure. Finally integrated procedures based on robust statistical and numerical models have been implemented to interpret and exploit SHM outputs to assess the structural conditions of the investigated CH buildings.

During the Łate Cretaceous to Palaeogene, the Magura Basin was supplied by clastic material from source areas situated on the northern and southern margins of the basin, which do not outcrop on the surface at present. The northern source area is traditionally connected with the Silesian Ridge, whereas the position of the southern one is still under discussion. A source area situated SE of the Magura Basin supplied the Eocene pebbly para-conglomerates containing partly exotic material. The studied clastic material contains fragments of crystalline rocks, and frequent clasts of Mesozoic to Palaeogene deep and shallow-water limestones. Numerous mica schists, scarce volcanites and granitoids as well as gneisses, quartzites and cataclasites were found in the group of crystalline exotic pebbles. Monazite ages of "exotic" mica-schist pebbles from the Tylicz, Zarzecze and Piwniczna-Mniszek sections document the Variscan 310±10 Ma age of metamorphic processes. The provenance of these exotic rocks could be connected with a remote source area located SE of the Magura Basin, which could be the NW part of the Dacia Mega Unit. The idea is strongly supported by palaeotransport directions from the SE, the absence of material derived from the Pieniny Klippen Belt, the presence of shallow water limestones, typical facies of the Median Dacides belt and metamorphic age distribution proved by monazite dating.

The banks of the River Seine in Paris are inscribed on the UNESCO List of the World Cultural Heritage since 1991 because they are studded with a succession of masterpieces such as Notre- Dame Cathedral, Sainte Chapelle, Louvre, Place de la Concorde, Tour Eiffel, and with prestigious museums: Louvre, Orsay, Quai Branly, Petit Palais…Unfortunately, these banks are crossed by the Pompidou urban motorway, an important and continuous source of atmospheric pollution. The aim of the Project is to evaluate the evolution of the weathering of limestone, glass and stained glass in the centre of Paris in the 21rst century by crossing Climate and Pollution Models with Dose-Response Functions (DRF) for limestone, glass and stained glass and with Climatology of Salt Transitions for limestone. A Lutetian limestone (« Courville Stone ») has been used for the construction and the restoration of the most important monuments (Notre-Dame, Louvre…) and haussmannian buildings in Paris. It has a fine grain, a medium porosity (19%) and contains 90% of CaO. The modern glass of windows and large contemporaneous façades has a Si-Ca-Na composition, it is chemically inert, has a low thermal inertia, a flat surface, no open porosity and no surface roughness, therefore it is very durable. The glass of stained glass windows has a Si-Ca-K composition and it is low durable. Using different climate and pollution scenarios of the 21rst century, the project will evaluate different schemes of material degradations: (i) - Recession of limestone surface; (ii) - Soiling of limestone surface; (iii) - Soiling of modern glass; (iv) - Leaching of ancient stained glass windows; (v) - Deterioration of limestone by salts. The British Hadley Models, the French Météo- France Arpège-Aladin Models and the ENSEMBLES Approach will be crossed with DRF and Climatology of Salts Transitions. An in-the-field inventory (stock at risk) of the surface occupied on the façades by each kind of material (stone

The Ecology of Coral Reef Top Predators in the Papahānaumokuākea Marine National Monument

Jonathan J. Dale

2011-01-01

Full Text Available Coral reef habitats in the Papahānaumokuākea Marine National Monument (PMNM are characterized by abundant top-level predators such as sharks and jacks. The predator assemblage is dominated both numerically and in biomass by giant trevally (Caranx ignobilis and Galapagos sharks (Carcharhinus galapagensis. A lower diversity of predatory teleosts, particularly groupers and snappers, distinguishes the PMNM from other remote, unfished atolls in the Pacific. Most coral reef top predators are site attached to a “home” atoll, but move extensively within these atolls. Abundances of the most common sharks and jacks are highest in atoll fore reef habitats. Top predators within the PMNM forage on a diverse range of prey and exert top-down control over shallow-water reef fish assemblages. Ecological models suggest ecosystem processes may be most impacted by top predators through indirect effects of predation. Knowledge gaps are identified to guide future studies of top predators in the PMNM.

Sugaring marble in the Monumental Cemetery in Bologna (Italy): characterization of naturally and artificially weathered samples and first results of consolidation by hydroxyapatite

Sassoni, Enrico; Franzoni, Elisa

The so-called sugaring of marble is a very common degradation phenomenon, affecting both historical monuments and modern buildings, which is originated by environmental temperature fluctuations. Thermal cycles are indeed responsible for micro-cracks formation at the boundaries between calcite grains, so that marble is subjected to granular disintegration and can be reduced to a sugar-like powder of isolated calcite grains by just the pressure of a finger. Since no effective, compatible and durable treatment for sugaring marble consolidation is currently available, in this paper a novel consolidating treatment recently proposed for limestone, based on the formation of hydroxyapatite inside the stone, was investigated for weathered marble. To test the new treatment on suitably decayed marble samples, some naturally sugaring marbles from the Monumental Cemetery in Bologna (Italy, nineteenth century) were firstly characterized by scanning electron microscope (SEM), mercury intrusion porosimetry (MIP) and ultrasonic pulse velocity (UPV) measurement. Then, artificially weathered samples were produced by heating fresh Carrara marble samples at 400 °C for 1 h. The effects of artificial weathering were characterized using the same techniques as above, and a very good agreement was found between microstructure and mechanical features of naturally and artificially weathered samples. Then, the hydroxyapatite-based treatment was tested on the so-obtained artificially weathered samples, and the treatment effects were characterized by UPV, MIP and SEM equipped with energy dispersive spectrometry and Fourier transform infrared spectroscopy. The hydroxyapatite-based treatment exhibited a remarkable ability of restoring marble cohesion and a good compatibility in terms of modifications in pore size distribution, which leads to regard this treatment as a very promising consolidant for weathered marble.

`Adrir'Scott, Michael

2012-12-01

Massively multiplayer online role-playing games (MMORPGs) produce dynamic socio-ludic worlds that nurture both culture and gameplay to shape experiences. Despite the persistent nature of these games, however, the virtual spaces that anchor these worlds may not always be able to exist in perpetuity. Encouraging a community to migrate from one space to another is a challenge now facing some game developers. This paper examines the case of Guild Wars® and its "Hall of Monuments", a feature that bridges the accomplishments of players from the current game to the forthcoming sequel. Two factor analyses describe the perspectives of 105 and 187 self-selected participants. The results reveal four factors affecting attitudes towards the feature, but they do not strongly correlate with existing motivational frameworks, and significant differences were found between different cultures within the game. This informs a discussion about the implications and facilitation of such transitions, investigating themes of capital, value perception and assumptive worlds. It is concluded that the way subcultures produce meaning needs to be considered when attempting to preserve the socio-cultural landscape.

Fort Pulaski National Monument is located on Cockspur Island in Chatham County, Georgia, within the Atlantic Coastal Plain province. The island lies near the mouth of the Savannah River, and consists of small mounds (hummocks), salt marshes, and sediment dredged from the river. A 1,017-foot (ft) (310-meter [m])-deep core drilled at Cockspur Island in 2010 by the U.S. Geological Survey revealed several sedimentary units ranging in age from 43 million years old to present. Sand and mud are present at drilling depths from 0 to 182 ft (56 m), limestone is present at depths from 182 ft (56 m) to 965 ft (295 m), and glauconitic sand is present at depths from 965 ft (295 m) to 1,017 ft (310 m). The limestone and the water within the limestone are referred to collectively as the Floridan aquifer system, which is the primary source of drinking water for the City of Savannah and surrounding communities. In addition to details of the subsurface geology, this fact sheet identifies the following geologic materials used in the construction of Fort Pulaski: (1) granite, (2) bricks, (3) sandstone, and (4) lime mud with oyster shells.

Surveys of juvenile hawksbills around Buck Island Reef National Monument, US Virgin Islands from 1994 to 1999 revealed distributional patterns and resulted in a total of 75 individual hawksbill captures from all years; turtles ranged from 23.2 to 77.7 cm curved carapace length (CCL; mean 42.1 ± 12.3 cm SD). Juveniles concentrated where Zoanthid cover was highest. Length of time between recaptures, or presumed minimum site residency, ranged from 59 to 1,396 days (mean 620.8 ± 402.4 days SD). Growth rates for 23 juveniles ranged from 0.0 to 9.5 cm year−1 (mean 4.1 ± 2.4 cm year−1SD). Annual mean growth rates were non-monotonic, with the largest mean growth rate occurring in the 30–39 cm CCL size class. Gastric lavages indicated that Zoanthids were the primary food source for hawksbills. These results contribute to our understanding of juvenile hawksbill ecology and serve as a baseline for future studies or inventories of hawksbills in the Caribbean.

Ongoing and extensive urbanisation may threaten important archaeological structures that are still buried in urban areas. The ground penetrating radar (GPR) method is the most promising alternative for resolving buried archaeological structures in urban territories. This paper presents a case study that involves a geophysical survey employing the surface three-dimensional (3D) GPR techniques, in order to archaeologically characterise the investigated areas. The site is located in the south-western sector of the historical centre of Lecce (Apulia, Italy), where the modern city overlaps the main public monuments of the Roman municipium of Lupiae, only partially preserved or excavated: the amphitheatre, the theatre, the baths and maybe also the Forum. GPR measurements, integrated with the results of archaeological excavations and the topographical surveys of the preserved remains, were carried out in several areas regarding sectors of the ancient roman city. The GPR data were collected along a dense network of parallel profiles. The GPR sections were processed applying specific filters to the data in order to enhance their information content. The GPR images significantly contributed in reconstructing the complex subsurface properties in these modern urban areas. Strong GPR reflections features were correlated with possible ancient structures and they were integrated in the digital archaeological map of the city.

Rates of soil disruption from hikers and vehicle traffic are poorly known, particularly for arid landscapes. We conducted an experiment in Organ Pipe Cactus National Monument (ORPI) in western Arizona, USA, on an air-dry very fine sandy loam that is considered to be vulnerable to disruption. We created variable-pass tracks using hikers, an all-terrain vehicle (ATV), and a four-wheel drive vehicle (4WD) and measured changes in cross-track topography, penetration depth, and bulk density. Hikers (one pass = 5 hikers) increased bulk density and altered penetration depth but caused minimal surface disruption up to 100 passes; a minimum of 10 passes were required to overcome surface strength of this dry soil. Both ATV and 4WD traffic significantly disrupted the soil with one pass, creating deep ruts with increasing passes that rendered the 4WD trail impassable after 20 passes. Despite considerable soil loosening (dilation), bulk density increased in the vehicle trails, and lateral displacement created berms of loosened soil. This soil type, when dry, can sustain up to 10 passes of hikers but only one vehicle pass before significant soil disruption occurs; greater disruption is expected when soils are wet. Bulk density increased logarithmically with applied pressure from hikers, ATV, and 4WD.

During the Late Cretaceous to Paleogene the Magura Basin was supplied with clastic material from, non-existing today, source areas situated on the northern and southern margins of the basin. The northern source area is traditionally connected with Silesian Ridge, whereas the position of the southern one is still under discussion. The Upper Eocene-Oligocene pebbly mudstones of the Tylicz/Krynica facies zone contain exotic material derived from the south-Magura source area. The studied pebbles and clasts contain fragments of crystalline rocks, derived from a continental type of crust, and frequent clasts of Mesozoic to Paleogene deep and shallow-water limestones. Volcanites, rarely granitoides as well as schists, gneisses, quartzites and cataclasites were found in the group of crystalline exotic pebbles. The isotopic ages of "exotic" pebbles from the Tylicz section document a Variscan age of plutonic and metamorphic rocks. The composition of the Tylicz exotic conglomerates occupied the transitional position between the Jarmuta/Proč (Maastrichtian-Lower Eocene) and Strihovce (Eocene) exotic pebbles. The provenance of these rocks could be connected with Eocene exhumation of the SE sector of the Magura Basin basement. Another possibility can be explain by supply of siliciclastic material from a SE source area (Dacia and Tisza Mega-Units) and carbonate material from a S source area (ALCAPA Mega-Unit: Central Carpathian Block and Pieniny Klippen Belt).

These remotely sensed, geographically referenced elevation measurements of Lidar-derived bare earth (BE) and first surface (FS) topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Northeast Coastal and Barrier Network, Kingston, RI; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate datasets of the George Washington Birthplace National Monument in Virginia, acquired on March 26, 2008. The datasets are made available for use as a management tool to research scientists and natural resource managers. An innovative airborne Lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL) was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) Lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive Lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multi-spectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for submeter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a Lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL

Coral, fish, plankton, and detritus samples were collected from coral reefs in Virgin Islands National Park (VIIS) and Virgin Islands Coral Reef National Monument (VICR) to assess existing contamination levels. Passive water sampling using polar organic chemical integrative samplers (POCIS) and semi-permeable membrane devices found a few emerging pollutants of concern (DEET and galaxolide) and polynuclear aromatic hydrocarbons. Very little persistent organic chemical contamination was detected in the tissue or detritus samples. Detected contaminants were at concentrations below those reported to be harmful to aquatic organisms. Extracts from the POCIS were subjected to the yeast estrogen screen (YES) to assess potential estrogenicity of the contaminant mixture. Results of the YES (estrogen equivalency of 0.17–0.31 ng/L 17-β-estradiol) indicated a low estrogenicity likelihood for contaminants extracted from water. Findings point to low levels of polar and non-polar organic contaminants in the bays sampled within VICR and VIIS.

The Jomac mine is in the White Canyon area. San Juan County, Utah, about 13 miles northeast of the town of White Canyon, Utah. The mine is owned by the Ellihill Mining Company, White Canyon, Utah. Mine workings consist pf two adits connected by a crosscut. Two hundred feet of exploratory drifting and 2,983.5 feet of exploratory core drilling were completed during 1953 by the owners with Defense Minerals Exploration Administration assistance. Sedimentary rocks exposed in the area of the Jomac mine are of Permian to Late Triassic age, having a combined thickness of more than 1,700 feet. An ancient channel, from 200 to 400 feet wide and about 4 feet deep, enters the mine area from the southwest, swinging abruptly northwest near the mine workings and continuing to the northern tip of the Jomac Hillo This channel was cut into the upper beds of the Moenkopi formation and filled in part by Chinle and in part by Shinarump sediments. This channel is marked by depressions that apparently were scoured into its floor; a tributary channel may have joined it from the southeast at a point near the mine workings. Chinle beds Intertongue with Shinarump beds along the southwestern part of the channel. After the main channel was partly filled by siltstone of the Chinle formation, the stream was apparently diverted into the tributary channel, and scours were cut into

Full Text Available Large trees play several vital roles in the Angkor monuments landscape. They protect biodiversity, enhance the tourism experience, and provide various ecosystem services to local residents. A clear understanding of forest composition and distribution of individual species, as well as timely monitoring of changes, is necessary for conservation of these trees. using traditional field work, obtaining this sort of data is time-consuming and labour-intensive. This research investigates classification of very high resolution remote sensing data as a tool for efficient analyses. QuickBird satellite imagery was used to clarify the tree species community in and around Preah Khan temple, to elucidate differences in ecological traits among the three dominant species (Dipterocarpus alatus, Lagerstroemia calyculata and Tetrameles nudiflora, and to identify crowns of the dominant species.

2017-01-01

Tule Springs Fossil Beds National Monument (TUSK) preserves 22,650 acres of the upper Las Vegas Wash in the northern Las Vegas Valley (Nevada, USA). TUSK is home to extensive and stratigraphically complex groundwater discharge (GWD) deposits, called the Las Vegas Formation, which represent springs and desert wetlands that covered much of the valley during the late Quaternary. The GWD deposits record hydrologic changes that occurred here in a dynamic and temporally congruent response to abrupt climatic oscillations over the last ~300 ka (thousands of years). The deposits also entomb the Tule Springs Local Fauna (TSLF), one of the most significant late Pleistocene (Rancholabrean) vertebrate assemblages in the American Southwest. The TSLF is both prolific and diverse, and includes a large mammal assemblage dominated by Mammuthus columbi and Camelops hesternus. Two (and possibly three) distinct species of Equus, two species of Bison, Panthera atrox, Smilodon fatalis, Canis dirus, Megalonyx jeffersonii, and Nothrotheriops shastensis are also present, and newly recognized faunal components include micromammals, amphibians, snakes, and birds. Invertebrates, plant macrofossils, and pollen also occur in the deposits and provide important and complementary paleoenvironmental information. This field compendium highlights the faunal assemblage in the classic stratigraphic sequences of the Las Vegas Formation within TUSK, emphasizes the significant hydrologic changes that occurred in the area during the recent geologic past, and examines the subsequent and repeated effect of rapid climate change on the local desert wetland ecosystem.

Prediction of elastic and acoustic behaviors of calcarenite used for construction of historical monuments of Rabat, Morocco

Directory of Open Access Journals (Sweden)

Full Text Available Natural materials (e.g. rocks and soils are porous media, whose microstructures present a wide diversity. They generally consist of a heterogeneous solid phase and a porous phase which may be fully or partially saturated with one or more fluids. The prediction of elastic and acoustic properties of porous materials is very important in many fields, such as physics of rocks, reservoir geophysics, civil engineering, construction field and study of the behavior of historical monuments. The aim of this work is to predict the elastic and acoustic behaviors of isotropic porous materials of a solid matrix containing dry, saturated and partially saturated spherical pores. For this, a homogenization technique based on the Mori–Tanaka model is presented to connect the elastic and acoustic properties to porosity and degree of water saturation. Non-destructive ultrasonic technique is used to determine the elastic properties from measurements of P-wave velocities. The results obtained show the influence of porosity and degree of water saturation on the effective properties. The various predictions of Mori–Tanaka model are then compared with experimental results for the elastic and acoustic properties of calcarenite.

There are 1,130 architectural ancient monuments in the historic center in Morelia, Michoacan, Mexico built with ignimbrites from the surrounding quarry stones. In some facades is acute the damage. The walls are between 0.50 and 1.50 meters wide, it helps the structure under seismic or accidental loads. The main winds come from the S-SW and their ratio speed (4-20 m/s) does not allow mechanical corrosion (corrosion) but it is able to carry anthropogenic particles (2-25 m), form the burnt of fossil fuels, and they lay on the facades. The damage is observed specially on the facades on the dominant winds and also on the facades located on streets less than 6.0 m wide. The capillary humidity is visible until highs of 2.0 meters on the streets, and it is appreciate the efflorescence crystals and biologic patinas. We performance non destructive tests in situ with the Schmidt hammer to quantify the mechanical resistance on the ignimbrite blocks forming the buildings, in the lowest part of them we took the data because the damage is acute in that wet zone and because in this part could occur the collapse in an extraordinary earthquake. The collected data were compared with the data obtained in ignimbrites blocks taken from the 'healthy' quarry stones. (Author)

Understanding and managing experiential aspects of soundscapes at Muir woods national monument.

Research has found that human-caused noise can detract from the quality of the visitor experience in national parks and related areas. Moreover, impacts to the visitor experience can be managed by formulating indicators and standards of quality as suggested in park and outdoor recreation management frameworks, such as Visitor Experience and Resource Protection (VERP), as developed by the U.S. National Park Service. The research reported in this article supports the formulation of indicators and standards of quality for human-caused noise at Muir Woods National Monument, California. Phase I identified potential indicators of quality for the soundscape of Muir Woods. A visitor "listening exercise" was conducted, where respondents identified natural and human-caused sounds heard in the park and rated the degree to which each sound was "pleasing" or "annoying." Certain visitor-caused sounds such as groups talking were heard by most respondents and were rated as annoying, suggesting that these sounds may be a good indicator of quality. Loud groups were heard by few people but were rated as highly annoying, whereas wind and water were heard by most visitors and were rated as highly pleasing. Phase II measured standards of quality for visitor-caused noise. Visitors were presented with a series of 30-second audio clips representing increasing amounts of visitor-caused sound in the park. Respondents were asked to rate the acceptability of each audio clip on a survey. Findings suggest a threshold at which visitor-caused sound is judged to be unacceptable, and is therefore considered as noise. A parallel program of sound monitoring in the park found that current levels of visitor-caused sound sometimes violate this threshold. Study findings provide an empirical basis to help formulate noise-related indicators and standards of quality in parks and related areas.

A refreshing alternative to the pilgrimage to the Holy Sepulchre: the monumental burials of Christ in France (XVth-XVIth centuries

Full Text Available In the 1420’s in France some groups of sculptures appeared representing the life-size burial of Christ. These monumental “Entombments” experienced a strong expansion from the mid-15th century until approximately 1520, in France as well in bordering regions such as Belgium, Germany, Switzerland and Italy. From the end of the 19th century they were studied in a primarily stylistic perspective while the problem of their functions and uses have been addressed only very recently. The intent here is to appraise the hypothesis according to which they would have served as substitutes in a spiritual pilgrimage. First the study considers the situation of the pilgrimage in the Holy Land during the 15th century, then it analyzes the relationships between images and indulgences. Finally it ends with the examination of a number of burials accompanied by indulgences, that could be utilised as supports of a spiritual pilgrimage.

"Through Minos blocks escape by sea and land / the unconfined skies remain …": The Icarus Figure on the Sepulchral Monuments of Noricum and Pannonia

Directory of Open Access Journals (Sweden)

Katarina Šmid

2012-07-01

Full Text Available The motif of Icarus is richly represented in small objects, such as gems and cameos, as well as in wall paintings, but appears only rarely in stone sculpture. As pointed out by Arnold Schober, it has achieved its greatest popularity in Noricum and especially in Pannonia: outside these provinces, a larger number is represented only in Regio X Venetia et Histria. Icarus is accompanied by Daedalus or one of the Parcae, who is attaching wings to his arms. The majority of the statuettes shows Icarus standing, naked or draped only in a chlamys, with large wings attached to his shoulders. Since the Roman Empire has so few representations of the young hero just before or during the fight, Schober has labelled this motif as a special feature of Norico-Pannonian sepulchral monuments. Most of the statuettes were found in the territory of a Roman necropolis, and they apparently belonged to the decoration of the sepulchral monuments. They usually served as the acroteria of the tympanums of the aedicule tomb, which is confirmed by their more or less rudimentary workmanship and in some cases by a pair of holes in the plinth. Icarus was also one of the rare mythological motifs depicted on the sepulchral monuments of the eastern part of Gallia Cisalpina, where it doubtlessly decorated the acroterium. Statues were found in the necropolises of Aquileia and Altinum. All date to the Julio-Claudian era and resemble those from Noricum and Pannonia. The theme probably came to the Danubian provinces with a time delay through well-established merchant connections. The high-quality fragment from Flavia Solva shows sitting on Icarus’ left side a naked woman, usually interpreted as one of the Parcae, who is securing his wings. In this position she replaces Daedalus, who is sculpted beside Icarus especially from the 5th  century BC onward. She might be an allusion to Icarus’ premature death. An almost identical composition is found in a wall painting from Echzell

Delineation and hydrologic effects of a gasoline leak at Stovepipe Wells Hotel, Death Valley National Monument, California

Science.gov (United States)

Buono, A.; Packard, Elaine M.

1982-01-01

Ground water is the only local source of water available to the Stovepipe Wells Hotel facilities of the Death Valley National Monument, California. A leak in a service station storage tank caused the formation of a gasoline layer overlying the water table, creating the potential for contamination of the water supply. The maximum horizontal extent of the gasoline layer was mathematically estimated to be 1,300 feet downgradient from the leaky gasoline tank. Exploratory drilling detected the gasoline layer between 900 and 1,400 feet downgradient and between 50 and 150 feet upgradient from the source. Traces of the soluble components of gasoline were also found in the aquifer 150 feet upgradient, and 250 feet distant from the source perpendicular to the direction of ground-water movement. The gasoline spill is not likely to have an effect on the supply wells located 0.4 mile south of the leak source, which is nearly perpendicular to the direction of ground-water movement and the primary direction of gasoline movement in the area. No effect on phreatophytes 2 miles downgradient from the layer is likely, but the potential effects of gasoline vapors within the unsaturated zone on local xerophytes are not known. (USGS)

Secondary Sulfate Mineralization and Basaltic Chemistry of Craters of the Moon National Monument, Idaho: Potential Martian Analog

Energy Technology Data Exchange (ETDEWEB)

2012-05-01

Secondary deposits associated with the basaltic caves of Craters of the Moon National Monument (COM) in southern Idaho were examined using X-ray powder diffraction, X-ray fluorescence spectrometry, Fourier transform infrared spectrometry, and Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS). The secondary mineral assemblages are dominated by Na-sulfate minerals (thenardite, mirabilite) with a small fraction of the deposits containing minor concentrations of Na-carbonate minerals. The assemblages are found as white, efflorescent deposits in small cavities along the cave walls and ceilings and as localized mounds on the cave floors. Formation of the deposits is likely due to direct and indirect physiochemical leaching of meteoritic water through the overlying basalts. Whole rock data from the overlying basaltic flows are characterized by their extremely high iron concentrations, making them good analogs for martian basalts. Understanding the physiochemical pathways leading to secondary mineralization at COM is also important because lava tubes and basaltic caves are present on Mars. The ability of FTICR-MS to consistently and accurately identify mineral species within these heterogeneous mineral assemblages proves its validity as a valuable technique for the direct fingerprinting of mineral species by deductive reasoning or by comparison with reference spectra.

Actually, acid rain is considered as a potential problem that affects materials and ecosystems. The effect on monuments, made mainly from limestone, has been studied for long time. In this work, a sample of limestone from Tulum, Qintana Roo, was studied. The following parameters were measured: density, porosity and percentage of water adsorption. Also, the sample was irrigated with acid rain prepared in the laboratory (pH = 4.6), based in the chemical composition of 56 rain samples from Puerto Morelos, Quintana Roo, in 1994 and 1995. The results obtained show that acid rain is neutralized by calcium carbonate from the limestone. The high calcium concentrations in the effluent, show that limestone is dissolved by acid rain. Superficial recession was 4.4 {mu}m/year under experimental conditions used. [Spanish] Actualmente la lluvia acida se ha convertido en un problema potencial que afecta en mayor o menor grado a materiales y a los ecosistemas. El efecto que causa la lluvia acida en monumentos construidos fundamentalmente de roca caliza, ha sido objeto de muchas investigaciones realizadas, prioritariamente, por paises que poseen estructuras, cuyo material de construccion es caliza. En este trabajo de investigacion se estudio una muestra de roca caliza proveniente de los monumentos mayas de Tulum, Quintana Roo. Se determinaron los parametros de densidad, porosidad y porcentaje de adsorcion de agua. Asimismo, se efectuo la irrigacion de la muestra con lluvia acida (pH aprox.4.6), preparada en el laboratorio con base en la composicion quimica que se determino en 56 muestras de agua de lluvia provenientes de Puerto Morelos, punto cercano a los monumentos de Tulum, Quintana Roo, durante los anos 1994 y 1995. Los resultados permiten concluir que la lluvia acida sufre un proceso de naturalizacion con el carbonato de calcio de la roca caliza. Las altas concentraciones de calcio en el efluente, mostraron que la roca caliza sufrio una disolucion con la lluvia acida. La

Distribution and Diversity of Bacteria and Fungi Colonization in Stone Monuments Analyzed by High-Throughput Sequencing.

Li, Qiang; Zhang, Bingjian; He, Zhang; Yang, Xiaoru

The historical and cultural heritage of Qingxing palace and Lingyin and Kaihua temple, located in Hangzhou of China, include a large number of exquisite Buddhist statues and ancient stone sculptures which date back to the Northern Song (960-1219 A.D.) and Qing dynasties (1636-1912 A.D.) and are considered to be some of the best examples of ancient stone sculpting techniques. They were added to the World Heritage List in 2011 because of their unique craftsmanship and importance to the study of ancient Chinese Buddhist culture. However, biodeterioration of the surface of the ancient Buddhist statues and white marble pillars not only severely impairs their aesthetic value but also alters their material structure and thermo-hygric properties. In this study, high-throughput sequencing was utilized to identify the microbial communities colonizing the stone monuments. The diversity and distribution of the microbial communities in six samples collected from three different environmental conditions with signs of deterioration were analyzed by means of bioinformatics software and diversity indices. In addition, the impact of environmental factors, including temperature, light intensity, air humidity, and the concentration of NO2 and SO2, on the microbial communities' diversity and distribution was evaluated. The results indicate that the presence of predominantly phototrophic microorganisms was correlated with light and humidity, while nitrifying bacteria and Thiobacillus were associated with NO2 and SO2 from air pollution.

Pecos National Monument, New Mexico: Its Geologic Setting

Science.gov (United States)

Johnson, Ross Byron

1969-01-01

The ruins of the pueblos and missions of Pecos lie on the east bank of Glorieta Creek near its junction with the Pecos River at the south end of the Sangre de Cristo Mountains in north-central New Mexico. Here the Pecos River and Glorieta Creek have formed a broad rolling valley in which the red adobe walls of the mission church stand as a striking monument to a historic past. This is beautiful country; the bright hues of red rocks are complemented by the varied greens of the junipers, pi?ons, and ponderosa pines. Northward the Sangre de Cristo Mountains stretch for miles in a blue mist toward the Truchas Peaks and forests of the Pecos Wilderness. A few miles south of the ruins the steep high escarpment of Glorieta Mesa marks, in a general way, the southern termination of the Rocky Mountain System, which here is represented by the Sangre de Cristos. The escarpment of Glorieta Mesa has been formed largely by the Pecos River and its tributaries eroding the soft sedimentary layers. The Pecos flows southward from the high mountains in the north, parallels the mesa escarpment for 15 miles, and breaches the mesa near San Jose. About 1-1/2 miles southwest of the Pecos ruins at Cerro de Escobas is the highest point on Glorieta Mesa. It is the most conspicuous feature of the local landscape and rises to an elevation of 8,212 feet - 1,270 feet above the ruins. The slope of the escarpment here is very steep, rising 6 feet in every 10 horizontal feet. Along the north side of the Glorieta Mesa escarpment is a 30-mile-long natural pass around the south end of the Sangre de Cristos that extends from Canoncito on the west to Starvation Peak on the east (fig. 1). The elevation of the pass is greater than 6,000 feet at all places, and it reaches its summit of 7,432 feet near the village of Glorieta near the west end of the pass. This pass has been used as a major travel route for more than 800 years by the Indians, Spanish, and Americans. The famous Santa Fe Trail passed through

define the theoretical relationship existing between solar dynamics and the monument. Yet the information deduced from such a model, that could be easily examined by a user system realised on computer, had to be compared with real data obtained by thermographic surveys. This comparison was aimed to evaluate the contribution that other climatic phenomena and/or the dishomogeneities in the constituent materials could give to the recorded thermal distribution and then to the global thermal system. In other words, it was necessary to accomplish seasonal campaigns on field aimed to evaluate the significance of the theoretically computed data and then the reliability of the model as a way to foretell the actual behaviour of the monument from a thermodynamic point of view. The operative problem was to find locations that could be useful to accomplish significant recordings of the thermal behaviour of the various elements that constitute the Dome. A useful place was Giotto's bell-tower but it allowed a partial vision of the structure, it was instead necessary to obtain recordings, that could be considered practically instantaneous, of the whole dome. It was therefore necessary to flank the seasonal campaigns accomplished from the bell-tower with a survey accomplished by air recordings from an helicopter. Security reasons and the high costs (in terms of resources and persons) of such an investigation compelled to optimise times and methods of air recordings. To this purpose the user system was used with the aim of defining a period that could conciliate the operative needs with the necessity of evaluating the significance of the mathematical model. A short description of this case will be exposed to underline both the differences and the similarities between these two different ways to accomplish aerial multispectral analysis.

Diversification as a Circumvention Strategy to Institutional Constraints in China

DEFF Research Database (Denmark)

Xie, Peihong; Li, Xin; Wu, Sibin

While unrelated diversification (i.e., conglomeration) is deemed value-destroying in the West, many Chinese private firms have been enthusiastically pursuing such a growth strategy. Conventional institutional view of diversification sees conglomerates as responses to market imperfections...... in emerging economies and believes conglomeration is value-creating because conglomerates can effectively fill the institutional voids in the emerging markets. Our literature review shows that the conventional institutional view on conglomeration mainly focuses on the value-creating aspects while neglects...... the socially counterproductive rent-seeking aspects of conglomeration strategy in institution-weak countries (Khanna & Palepu, 2000). In this paper, we fill the gap by examining some unconventional diversifications and point out their rent-seeking nature in China. We have proposed an official...

Lipid residues preserved in sheltered bedrock features at Gila Cliff Dwellings National Monument, New Mexico

Bedrock features represent various economic, social, and symbolic aspects of past societies, but have historically received little study, particularly in North America. Fortunately, new techniques for analyzing spatial configurations, use-wear, and organic residues are beginning to unlock more of the interpretive potential of these features. Though preliminary in nature, the present study contributes to this trend by documenting an application of lipid analysis to bedrock features in a dry rockshelter. Results of this initial application indicate that bedrock features in dry rockshelters may provide especially favorable conditions for the preservation and interpretation of ancient organic residues. Abundant lipids, comparable to concentrations present in some pottery sherds, were extracted from a bedrock grinding surface at Gila Cliff Dwellings National Monument and analyzed using gas chromatography-mass spectrometry. Though the lipids were highly oxidized, degradation products indicative of former unsaturated fatty acids were retained. Comparisons to experimentally aged residues, and absence of a known biomarker for maize, indicate that the bulk of the lipids preserved in the milling surface probably derive from processing an oily nut or seed resource, and not from processing maize. Substantially lower amounts of lipids were recovered from a small, blackened cupule. It is hypothesized that some portion of the lipids in the blackened cupule was deposited from condensed smoke of cooking and heating fires in the caves. Potential for the preservation of organic residues in similar sheltered bedrock contexts is discussed, and a practical method for sampling bedrock features in the field is described.

The Underwater Recovery of Monumental Marble Column Drums from an Ancient Shipwreck at Kızılburun, Turkey

Carlson, Deborah N.

2016-08-01

In the first century B.C., a stone carrier sank off the Aegean coast of Turkey at Kızılburun transporting all the elements of a monumental marble column, including a single Doric capital and eight drums. The 60-tonne cargo lay at a depth of 45-48 m and was excavated in its entirety by the Institute of Nautical Archaeology at Texas A&M University between 2005 and 2011. Ongoing research has shown that the Doric column pieces in the Kızılburun cargo originated in the marble quarries on Proconnesus Island in the Sea of Marmara and were very likely heading for the Temple of Apollo at Claros when the ship sank just 50 km short of its destination. The complete recovery of the ship's cargo posed a unique set of methodological challenges involving lifting the multi-tonne marble drums without disturbing the delicate waterlogged wooden hull remains preserved beneath. This report summarizes the solutions developed over five seasons in order to rig, hoist, move, and ultimately raise to the surface eight large ancient marble column drums (as well as all the other marble artifacts in the cargo) from a depth of almost 50 m under water.

Geochronological constraints on Cretaceous-Paleocene volcanism in South Westland, New Zealand

Phillips, C.J.; Cooper, A.F.; Palin, J.M.; Nathan, S.

2005-01-01

Cretaceous and Paleocene sedimentation in South Westland, New Zealand, is recorded in the Otumotu Formation, Tauperikaka Coal Measures, Whakapohai Sandstone, Arnott Basalt, Buttress Conglomerate, and Tokakoriri Formation, originally named and mapped by Nathan in 1977. Within this stratigraphic sequence, the name Buttress Conglomerate was used to describe volcanic conglomerates at Porphyry and Buttress Points that contained rounded clasts of plagioclasephyric intermediate volcanic rocks. Stratigraphically, the volcanic conglomerate at Porphyry Point forms sharp contacts with the underlying Arnott Basalt (Haumurian) and overlying Tokakoriri Formation (Teurian). The volcanic conglomerate at Buttress Point, however, is entirely fault-bounded. Clasts from each unit were collected and U-Pb zircon dated using the TIMS and ELA-ICP-MS methods. A trachyandesite clast collected at Buttress Point gives an age of 96.9 ± 1.6 Ma, whereas a rhyolite clast collected at Porphyry Point gives an age of 61.4 ± 0.8 Ma. Petrological, geochemical, and stratigraphic data suggest that erosion of the clasts closely followed volcanism, and that these ages accurately reflect the depositional ages of the conglomerates. Conglomerates at Porphyry and Buttress Points have been formally renamed the Porphyry Point Member of the Tokakoriri Formation and the Buttress Point Conglomerate, respectively.

Full Text Available RESUMEN: Se estudian los restos de una construcción romana localizada junto al río Alhama, en las inmediaciones de la ciudad de Graccurris (Alfaro, La Rioja. La obra fue expoliada ya en época antigua, por lo que apareció incompleta, con buena parte de los materiales arquitectónicos que formaban parte de ella desplazados de su posición original. Los restos en mejor estado de conservación corresponden a una presa construida con grandes sillares de arenisca. A partir de los materiales arquitectónicos aislados respetados por el expolio, se puede restituir un gran conjunto monumental que, además de la presa, contaba con una fuente o ninfeo y un pequeño templo. Se documenta el paso por el sitio de la vía De Italia in Hispanias, ya que apareció también un miliario de Augusto. Tras ser expoliada, la obra fue definitivamente sepultada por un potente estrato de aluvión aportado por una crecida del Alhama. En este estrato la excavación proporcionó material cerámico romano, sin restos de épocas posteriores, lo que permite datar esta inundación hacia finales del siglo II.ABSTRACT: A study is made of Román remains located beside the Alhama River near the city of Gracurris (Alfaro, La Rioja. The site had already been plundered in ancient times so it was incomplete when uncovered, and a large number of the architectural materials had been moved from their original positions. The remains that are in the best state of preservation are those of a dam built of large sandstone blocks. A large monumental group can be restored from the isolated architectural materials left that were not plundered, including a nymphaeum and a small temple, in addition to the dam. It can also be shown that the Román road De Italia in Hispanias went through this site, since an Augustan milestone has also been found. After having been plundered, the site was completely buried by a layer of alluvium brought by a rise in the Alhama River. Román ceramic materials were

Assessment of metal and trace element contamination in water, sediment, plants, macroinvertebrates, and fish in Tavasci Marsh, Tuzigoot National Monument, Arizona

Tavasci Marsh is a large freshwater marsh within the Tuzigoot National Monument in central Arizona. It is the largest freshwater marsh in Arizona that is unconnected to the Colorado River and is designated as an Important Bird Area by the Audubon Society. The marsh has been altered significantly by previous land use and the monument’s managers are evaluating the restoration of the marsh. In light of historical mining activities located near the marsh from the first half of the 20th century, evaluations of water, sediment, plant, and aquatic biota in the marsh were conducted. The evaluations were focused on nine metals and trace elements commonly associated with mining and other anthropogenic activities (As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn) together with isotopic analyses to understand the presence, sources and timing of water and sediment contaminants to the marsh and the occurrence in aquatic plants, dragonfly larvae, and fish. Results of water analyses indicate that there were two distinct sources of water contributing to the marsh during the study: one from older high elevation recharge entering the marsh at Shea Spring (as well as a number of unnamed seeps and springs on the northeastern edge of the marsh) and the other from younger low elevation recharge or from Pecks Lake. Water concentrations for arsenic exceeded the U.S. Environmental Protection Agency primary drinking water standard of 10 μg/L at all sampling sites. Surface waters at Tavasci Marsh may contain conditions favorable for methylmercury production. All surficial and core sediment samples exceeded or were within sample concentration variability of at least one threshold sediment quality guideline for As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn. Several sediment sites were also above or were within sample concentration variability of severe or probable effect sediment quality guidelines for As, Cd, and Cu. Three sediment cores collected in the marsh have greater metal and trace element concentrations

Dolmens are the most conspicuous remains of the populations of the 4th and first half of 3rd millennia BCE. These tombs are impressive not only for their monumentality, but also because of the socioeconomic investment they represent for those Neolithic communities, namely from the Central-South of Portugal, who built them. Although dolmens have been studied for their funerary content and typologies, an interdisciplinary approach toward the geological characterization and sourcing of stones used in these constructions has not received enough attention from researchers. With MEGAGEO project a multidisciplinary group of geologist and archaeologists intends to assess the relationship between the distribution of dolmens in Central-South Portugal, their source materials, and the geological landscape. GIS will map the information gathered and will be used to analyse these relationships. The selection of the areas, with distinctive geologies (limestone vs granite), will allow to verify if human patterns of behaviour regarding the selection of megaliths are similar or different regionally. Geologically the first target area (Freixo, Alentejo) is dominated by a small intrusion of gabbro mingled/mixed within a granodioritic intrusion both related with variscan orogeny. Granodiorite exhibit several enclaves of igneous and metamorphic nature attesting the interaction between both igneous rocks as well with enclosing gneisses. Despite Alentejo region have a reduced number of outcrops the granodiorite provides rounded to tabular metric blocks. The gabbro is very coarse grained, sometimes with a cumulate texture, and their fracturing and weathering provide very fresh tabular blocks. The five studied dolmens (Quinta do Freixo #1 to #5) are implanted in a large granodioritic intrusion, around the gabbroic rocks, within an area of approximately 9km2. The medium grained granodiorite is ubiquity in all the dolmens slabs and occasionally it can be observed features of mixing and

Medicine Lake volcano is among the very best places in the United States to see and walk on a variety of well-exposed young lava flows that range in composition from basalt to rhyolite. This field-trip guide to the volcano and to Lava Beds National Monument, which occupies part of the north flank, directs visitors to a wide range of lava flow compositions and volcanic phenomena, many of them well exposed and Holocene in age. The writing of the guide was prompted by a field trip to the California Cascades Arc organized in conjunction with the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) quadrennial meeting in Portland, Oregon, in August of 2017. This report is one of a group of three guides describing the three major volcanic centers of the southern Cascades Volcanic Arc. The guides describing the Mount Shasta and Lassen Volcanic Center parts of the trip share an introduction, written as an overview to the IAVCEI field trip. However, this guide to Medicine Lake volcano has descriptions of many more stops than are included in the 2017 field trip. The 23 stops described here feature a range of compositions and volcanic phenomena. Many other stops are possible and some have been previously described, but these 23 have been selected to highlight the variety of volcanic phenomena at this rear-arc center, the range of compositions, and for the practical reason that they are readily accessible. Open ground cracks, various vent features, tuffs, lava-tube caves, evidence for glaciation, and lava flows that contain inclusions and show visible evidence of compositional zonation are described and visited along the route.

Full Text Available The Súľov Conglomerates represent mass-transport deposits of the Súľov-Domaniža Basin. Their lithosomes are intercalated by claystones of late Thanetian (Zones P3 - P4, early Ypresian (Zones P5 - E2 and late Ypresian to early Lutetian (Zones E5 - E9 age. Claystone interbeds contain rich planktonic and agglutinated microfauna, implying deep-water environments of gravity-flow deposition. The basin was supplied by continental margin deposystems, and filled with submarine landslides, fault-scarp breccias, base-of-slope aprons, debris-flow lobes and distal fans of debrite and turbidite deposits. Synsedimentary tectonics of the Súľov-Domaniža Basin started in the late Thanetian - early Ypresian by normal faulting and disintegration of the orogenic wedge margin. Fault-related fissures were filled by carbonate bedrock breccias and banded crystalline calcite veins (onyxites. The subsidence accelerated during the Ypresian and early Lutetian by gravitational collapse and subcrustal tectonic erosion of the CWC plate. The basin subsided to lower bathyal up to abyssal depth along with downslope accumulation of mass-flow deposits. Tectonic inversion of the basin resulted from the Oligocene - early Miocene transpression (σ1 rotated from NW-SE to NNW-SSE, which changed to a transpressional regime during the Middle Miocene (σ1 rotated from NNE-SSW to NE-SW. Late Miocene tectonics were dominated by an extensional regime with σ3 axis in NNW-SSE orientation.

We present a multiproxy study of land use by a pre-Columbian earth mounds culture in the Bolivian Amazon. The Monumental Mounds Region (MMR) is an archaeological sub-region characterized by hundreds of pre-Columbian habitation mounds associated with a complex network of canals and causeways, and situated in the forest-savanna mosaic of the Llanos de Moxos. Pollen, phytolith, and charcoal analyses were performed on a sediment core from a large lake (14 km2), Laguna San José (14°56.97'S, 64°29.70'W). We found evidence of high levels of anthropogenic burning from AD 400 to AD 1280, corroborating dated occupation layers in two nearby excavated habitation mounds. The charcoal decline pre-dates the arrival of Europeans by at least 100 yr, and challenges the notion that the mounds culture declined because of European colonization. We show that the surrounding savanna soils were sufficiently fertile to support crops, and the presence of maize throughout the record shows that the area was continuously cultivated despite land-use change at the end of the earth mounds culture. We suggest that burning was largely confined to the savannas, rather than forests, and that pre-Columbian deforestation was localized to the vicinity of individual habitation mounds, whereas the inter-mound areas remained largely forested.

Full text: Nuclear techniques represent invaluable tools in non-destructive diagnostics applied to archaeological findings and objects of arts, mainly for dating and determining the composition of materials used in the production of artefacts. In this work we present the application of X-ray fluorescence analysis (XRFA). The X-ray fluorescence apparatus built and operated in the Laboratory of Quantitative Methods in Research of Ancient Monuments, constituent part of the Department of Dosimetry and Application of Ionizing Radiation, FNSPE, was used for the purpose of old relics measurements. The X-ray sources (radionuclides) generate the characteristic X-ray photons from the sample. After processing the resulting signal, we obtain information about the chemical composition of the tested sample. These results give data for qualitative and quantitative analysis of samples. XRFA is relatively simple and non-destructive method. Capability of in-situ measurement is one of big advantages of this method. The radionuclide sources of exciting radiation (e.g. 55 Fe enables the excitation of elements with Z up to 23, 238 Pu is used in interval of Z from 20 to 39 etc.) and X-ray tube with Mo anode were used. Narrow collimation of the exciting beam makes it possible to select the measured area of e.g. pigments in old manuscripts. X-ray fluorescence analysis, both in its energy form and in its wave dispersive form, is one of the most widespread methods using ionising radiation to study the elemental composition of materials. It is frequently used for studies of various cultural and historic relicts and objects of art. This work summarizes the author's experience with X-ray fluorescence analysis in investigating historical relicts namely by means of portable spectroscopic devices. Utilization of these methods is demonstrated in the investigation of fresco paintings, metal objects and old manuscripts. The results of these measurements provide the information on the composition of

Full Text Available Summary The research reported in the present paper focused on the behaviour of the Miocene sandstone used to build the Roman aqueduct at Zaghouan-Carthage and other Tunisian Heritage monuments, after application of water repellent and consolidating treatments as a preliminary to restoration. Commercial consolidants and water repellents were used in the experiments: two ethyl silicate consolidants, Tegovakon (TV and Keim-Silex OH (KSOH; two (siloxane water repellents, Tegosivin THE 328 (THE and Tegosivin HLJ00 (THE; and a dual (consolidate and water repellent action substance, Keim- Silex H (KSH (silicate acid ester base with siloxane. A mixed treatment consisting of successive coats of TV and THL (TVHL was also applied. These organosilicate consolidants and water repellents acted on the porous structure of the sandstone, reducing total porosity and water vapour permeability. The water repellent THE was found to affect these properties least, with a pore size distribution that resembled the distribution in the untreated sandstone most closely. Water repellents diminish water absorption and consolidants increase mechanical strength. The TV-THL mix, which yielded results similar to those obtained with water repellents alone, was unable to prevent the substantial scaling that occurs during (RILEM salt crystallisation-induced artificial ageing. The best results were found with the dual action consolidant! water repellent product (KSH, which improved the mechanical properties while affording protection from the decay caused by salts in artificial ageing trials. This substance was found to reduce water vapour permeability, however

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

The Summer of Applied Geophysical Experience (SAGE) class of 2017 carried out near-surface geophysical investigations of the Tyuonyi Pueblo of Bandelier National Monument, New Mexico in order to aid trail planning and identification of archeological features that could potentially be impacted. Tyuonyi is located in Frijoles Canyon, carved by the Rito de los Frijoles, between the SE flank of the Jemez Mountains and the Rio Grande, and contains pueblo room blocks, kivas and cavates that were occupied by ancestral Puebloans between 1350 and 1550 CE. SAGE collected seismic refraction, magnetic, electromagnetic (EM) and GPR data along targeted profiles and grids north and east of Tyuonyi Pueblo. Two 30 X 30 m grids of GPR data were recorded along 1-m spaced lines using the 250 MHz Sensors and Software NOGGIN® 250 Smart Tow and processed using the EKKO Project V5 program. Seismic refraction data were collected using a 48-channel Geometrics Strataview recorder and seven spreads with 0.5 m geophone spacing, a 6 m shot point interval, and a hammer source. Shot point offsets between 0.5 m and 48 m provided overlapping subsurface coverage. Seismic data from SAGE 2016 and 2017 were merged into a 168 m-long profile. Magnetic data were collected along 1-m spaced N-S lines in two 30 X 30 m grids and along the seismic line using a Geometrics 858 cesium vapor magnetometer. In addition, EM data were collected using a Geonics, EM-31 system along the seismic line. A velocity model was created to fit the seismic travel times. The GPR images and seismic model can be used to interpret the Quaternary geology of the site. These data trace incision of the Rito de los Frijoles into the Bandelier Tuff over several stages of the canyon development. The seismic model indicates a number of narrow, shallow channels carved into a broader strath. Holocene alluvial terrace deposits overlie the Bandelier Tuff surface, and the Tyuonyi Pueblo was constructed on top of the highest terrace. On the north

GC/MS in the study of deterioration process of historical monuments: characterization of the black crust formed in the Cathedral of Seville

Reyes, J.; Hermosin, B.; Saiz J, C.

2006-01-01

Here, we present an interesting application of Gas Chromatography/Mass Spectrometry (GC/MS) technique which permitted to differentiate successfully between natural and anthropogenic compounds present in the black crust formed in the Cathedral of Seville. This building, considered as one of the most important historic and cultural European monuments suffers from intense blackening of its outside walls and sculptures due to the interaction with the urban environment. Fragment of black crusts were removed from the Cathedral walls and extraction process with organic solvents was carried out. The aliphatic, aromatic and polar fractions were separated and analyzed using GC/MS. A complex organic composition of the black crusts indicated the accumulative character of the deposition process of atmospheric particles as a function of the time. The presence of high molecular weight n-alkanes, n-fatty acids and natural molecular markers identified during the study were indicative of current biogenic contributions. It was also found an important group of petrogenic molecular markers related with diesel soot emissions from motor engines. The diesel soot and molecular markers were entrapped within the black crust mineral matrix and contribute to the observed blackening of the Seville Cathedral. (Author)

A novel painted monument. Byzantine Art between Aesthetic Redefining and Dogmatic Perennity. The church Saint John the Baptist of Bârnova

Directory of Open Access Journals (Sweden)

Mihail M. Gheaţău

2015-11-01

Full Text Available Being remarkable through the monumentality and elegance of proportions, the architecture of the Church “Saint John the Baptist” from Bârnova derives from the so-called old Wallachian style, skillfully reshaping a structure which combines elements which are specific to Byzantine Balkanic ecclesiastical buildings. The unseen pictural work of Ștefan Constantinescu is characterized by the attempt to associate the results of experiencing freedom of interpretation and expression with the rules of the iconographic canon, inside the same ensemble. Its representations do not reproduce the traditional Byzantine manner, nor it is delivered as a form of quoting reality, but it is filtered and interpreted. From a theological point of view, the author respects the iconographic program, except for the topographic placement of some episodes, adapting the discourse according to the configuration and features of the liturgical space. We are in front of a case which places us in the position of managing the relationship between the value of artistic creation and the meticulosity of theological involvement. Neither Byzantine, nor realistic, the artistic solution of the mural painting from Bârnova is closer to the manner of iconic transfiguration than to the one of improvisation or artistic intermediation through which the daily tridimensional world is reflected.

Baik, A.; Yaagoubi, R.; Boehm, J.

2015-08-01

This work outlines a new approach for the integration of 3D Building Information Modelling and the 3D Geographic Information System (GIS) to provide semantically rich models, and to get the benefits from both systems to help document and analyse cultural heritage sites. Our proposed framework is based on the Jeddah Historical Building Information Modelling process (JHBIM). This JHBIM consists of a Hijazi Architectural Objects Library (HAOL) that supports higher level of details (LoD) while decreasing the time of modelling. The Hijazi Architectural Objects Library has been modelled based on the Islamic historical manuscripts and Hijazi architectural pattern books. Moreover, the HAOL is implemented using BIM software called Autodesk Revit. However, it is known that this BIM environment still has some limitations with the non-standard architectural objects. Hence, we propose to integrate the developed 3D JHBIM with 3D GIS for more advanced analysis. To do so, the JHBIM database is exported and semantically enriched with non-architectural information that is necessary for restoration and preservation of historical monuments. After that, this database is integrated with the 3D Model in the 3D GIS solution. At the end of this paper, we'll illustrate our proposed framework by applying it to a Historical Building called Nasif Historical House in Jeddah. First of all, this building is scanned by the use of a Terrestrial Laser Scanner (TLS) and Close Range Photogrammetry. Then, the 3D JHBIM based on the HOAL is designed on Revit Platform. Finally, this model is integrated to a 3D GIS solution through Autodesk InfraWorks. The shown analysis presented in this research highlights the importance of such integration especially for operational decisions and sharing the historical knowledge about Jeddah Historical City. Furthermore, one of the historical buildings in Old Jeddah, Nasif Historical House, was chosen as a test case for the project.

Extremadura is geologically located in the Iberian Massif, belonging part of the Central Iberian Zone, in the north of the region, and the Ossa Morena zone, in the south of it. The Central Iberian Zone is characterized by the abundance of clastic metasedimentary rocks and greywacke, sandstones, shales, conglomerates, quartzites and lesser amounts of carbonate materials such as limestone and dolomite (600-300 Ma). Also featured are Hercynian granitic intrusions. The rocks from the Ossa-Morena zone are metamorphic, intrusive igneous and volcanic (650-300 Ma). Extremadura, given its strategic geographical position, has been the site of human settlement since ancient times, and this civilisation has left its influence on the building materials used in buildings and monuments. The rocks used in building, are directly related to the geology of the immediate area, since rock outcrops, near the construction are mostly granites, slates and marbles. The historic and artistic heritage from Extremadura includes Roman treasures (like the bridges located in the Via de la Plata, dams, walls and milestones), Islamic and Christian treasures as well as medieval and Renaissance Jewish treasures. Extremadura has three World Heritage Sites declared by UNESCO: the old town of Cáceres, the archaeological site at Merida and the monastery of Guadalupe. The latter is built mainly of bricks and masonry. In Merida, granites and diorites of various facies of the batholiths located north of the city are used together with Sierra Carija's marble and quartzite alluvial gravels from the river Guadiana. Among the constructions in Merida, granite utilisation in the theater and amphitheater, aqueduct of Miracles and the Proserpina dam, are remarkable. The old town of Cáceres is characterised by the presence of narrow streets and monuments, medieval churches and Renaissance palaces, built with granite and flanked by a wall constructed during the Muslim period. This granite comes from the quarries

Peniocereus striatus (Brandegee) Buxb. (Cactaceae) is an endemic Sonoran Desert cactus that reaches its northern range limit in southwestern Arizona. One U.S. population occupies a small area of Organ Pipe Cactus National Monument near the U.S./Mexico international boundary, which has been monitored since 1939. An extensive survey conducted in 2002, covering 177 ha, resulted in the discovery of 88 new plants, in addition to the relocation of 57 plants found in previous surveys. Despite potential increases in population size and spatial distribution, mean plant height and number of basal stems has not significantly changed in recent years. Bud scars revealed that a majority of the population was sexually mature. Peniocereus striatus occurrence increased with decreasing slope, spanned every slope aspect, and was highest on rocky soils, but was noticeably low on west and northwest slopes and areas where severe land degradation had previously occurred. Over half of P. striatus plants were nursed by shrubs and subshrubs, while 40% occurred under leguminous trees. A severe frost in January 2002 top-killed 19% of the population, with the greatest damage in drainage bottoms. However, long-term (1944–2002) climate records show that there has been an overall increase in the number of frost free days in the region, which, coupled with land use change, has implications for the future health of this population.

De lo inmaterial literario al monumento arquitectónico: la casa museo de Ricardo Rojas / From the literary immateriality to the architectural monument: the House Museum of Ricardo Rojas

Amanda Salvioni

The House Museum of Ricardo Rojas, built in 1927 by the architect Angel Guido in Buenos Aires, is an ideal starting point for a reflection on the social uses of cultural heritage in Twentieth Century Argentina. The House reflects an aesthetic program that intended to reinvent the national tradition as a fusion between indigenous and Hispanic elements. Nonetheless, the national tradition codified by Rojas and Guido was the result of an arbitrary selection of heterogeneous elements that excluded immigrants and did not guarantee access to cultural heritage of all sectors of society. The project of the House was directly related to the emergence of cultural and politic nationalism that took place in Argentina from the Centenary of Independence in 1910 to the beginning of Second World War. This essay focuses on the contradictions of monumentalization of intangible cultural heritage in a multicultural society.

Armitage, R.A.; Hyman, M.; Rowe, M. W.

1997-01-01

On July 4, 1054 A.D. a supernova brighter than Venus appeared in the sky, remaining visible for approximately 23 days and 650 nights. It was chronicled in five independent historic accounts, four in China and one in Japan. For at least 40 years investigators have attributed certain distinctive rock paintings and carvings in the western United States as recordings of the 1054 A.D. supernova. More than twenty such depictions (circle or star-like symbols and a crescent) have been located. Two panels of rock paintings in Lava Beds National Monument, California, one at Fern Cave and one at Symbol Bridge, were listed as recording the 1054 A.D. supernova. The only direct means of assessing the likelihood that a 'supernova' representation records the 1054 A.D. event is to date the rock painting or carving. At Texas A and M University, was developed a plasma-chemical extraction technique that permits to analyze the 14 C in rock paintings, whether the pigments used were charcoal or inorganic Fe- and Mn- oxides and hydroxides with organic binder/vehicles. This paper presents direct 14 C age estimates on a rock painting suggested to represent the 1054 A.D. supernova. Charcoal pigment samples were collected from three figures in proximity at Fern Cave: a crescent pointing downward and two nearby circles, one above and one below the crescent. The AMS 14 C analysis on each sample using this technique show that these images do not represent the 1054 A.D. supernova

Environmental effects on deterioration of the historic monuments: case study of the ramparts of Sale's city - NW Morocco

The observation of differents shapes of weathering on ramparts of Sale city (black crust, efflorescence, alveolar, peeling, cracks...) reflects a very advanced degree of deterioration. They are essentially constituted by the gray calcarenite of the Plio-Quaternary (Sale's Stone) that characterizes himself by a middle toughness, and an elevated enough porosity. The different analyses (scaning electron microscopy, X-ray diffraction, ion chromatography and particle induced x-rays emission: PIXE) make on samples appropriated the long of ramparts (crusts, efflorescence, stone , mortar) permitted to identify a mineralogical phases present in these samples, and to quantity the soluble solt, the marine sprays as well as the heavy metals (Na, Mg, Al, Si, P, S, CI; Ca, Ti, V, Cr, Mn, Fe, Co, Ni,Cu, Zn, As, Br, Sr, Zr,Pb). The results can be generalized as follows: the first factor contains the elements originated from anthropogenic activities, and the second factor is composed of marine elements and soil dust. One noted an abundance of sulphates and chlorides that are going to crystallize and to form gypsum and halite while driving to the less porous crust formation. These last limit exchanges with the stone while provoking some different thermal and mechanical behaviors and there after the decay of the underlying material. The heavy metal presence (Pb, Zn, Cr, Cu, Ni) descended especially some fossil fuels, confirm the contribution of the atmospheric pollution in the phenomenon of deterioration of these ramparts. The gypsum detected are generally formed by oxidation of SO2 atmospheric what confirm the action of the atmospheric pollutants in the deterioration of these monuments

The main purpose of the work described in this paper has been to establish the protocol for a new non-disruptive technique of intervention, based on microwave treatment, for cleaning operations on monumental historical buildings, to eliminate biodeteriogens infesting stones. Non-destructive methods in the cleaning operations, should not only preserve the physical integrity, the chemical-mineralogical and structural identity of materials, but, when the exhalation of pollutant agents (like for example Radon gas) from building materials is considered, also, make the indoor air quality (IAQ) levels healthy. Therefore, one of the main steps of the protocol proposed in this paper is concerned with the assessment of the Radon exhalation rate in order to verify that microwave treatments do not increase the Radon naturally exhalated by building materials. In this paper, the preliminary results of the Radon measurements performed on two different type of tuff samples (grey tuff and yellow tuff), typical of the Italian traditional construction heritage, with the E-PERM passive technique at the Environmental Radioactivity Laboratory (Amb.Ra.), University of Salerno, Italy, ISO 9001:2008 certified, are summarized.

The remarkable endemism of moths at White Sands National Monument in New Mexico, USA, with special emphasis on Gelechioidea (Lepidoptera

Eric H. Metzler

2014-03-01

Full Text Available The white sands formation, a snow-white gypsum dunes system, is the world's largest gypsum dune field. White Sands National Monument protects about 40% of the dunes; the dunes formation as it is known today was formed ca. 8,000 years BP. Prior to 8,000 years BP, the area covered by the dunes was a wet cool forest of the last glacial maximum in North America. The dunes were formed as a result of the hypsithermal, a warming and drying period which followed the most recent glacial maximum. The white sands formation is located in south central New Mexico in the Tularosa Basin of southwestern United States. A 10-year study of moths at the dunes was commissioned by the U. S. National Park Service in 2006. Almost immediately species new to science were detected. In the period of 6 years, 30 new species were discovered in the dunes. Several of the new species are white or very pale in color, and are endemic to the dunes. The focus of the 10 year project was modified to emphasize naming the undescribed species which helps the National Park Service catalog and manage the habitats. The data should encourage other researchers to explore the interactions of the animals with the plants and the harsh desert environment, to study DNA and evolution, and to study the rapid adaptation which seems to be occurring.

The U.S. Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project consists of the Surface Project (Phase I) and the Ground Water Project (Phase II). Under the UMTRA Surface Project, tailings, radioactive contaminated soil, equipment, and materials associated with the former uranium ore processing at UMTRA Project sites are placed into disposal cells. The cells are designed to reduce radon and other radiation emissions and to minimize further contamination of ground water. Surface cleanup at the Monument Valley UMTRA Project site near Cane Valley, Arizona, was completed in 1994. The Ground Water Project evaluates the nature and extent of ground water contamination that resulted from the uranium ore processing activities. The Ground Water Project is in its beginning stages. Human health may be at risk from exposure to ground water contaminated by uranium ore processing. Exposure could occur by drinking water pumped out of a hypothetical well drilled in the contaminated areas. Adverse ecological and agricultural effects may also result from exposure to contaminated ground water. For example, livestock should not be watered with contaminated ground water. A risk assessment describes a source of contamination, how that contamination reaches people and the environment, the amount of contamination to which people or the ecological environment may be exposed, and the health or ecological effects that could result from that exposure. This risk assessment is a site-specific document that will be used to evaluate current and potential future impacts to the public and the environment from exposure to contaminated ground water. The results of this evaluation and further site investigations will be used to determine a compliance strategy to comply with the UMTRA ground water standards.

2017-04-01

This work expands upon detrital zircon geochronology with a sampling and analysis strategy dating granitoid conglomerate clasts that exhibit differing degrees of internal ductile deformation. As deformation textures within clastic material reflect the variation and history of tectonization in the source region of a deposit, we outline a dating methodology that can provide details of the provenance's tectonomagmatic history from deformation-relative age distributions. The method involves bulk samples of solely granitoid clasts, as they are representative of the magmatic framework within the provenance. The clasts are classified and sorted into three subsets: undeformed, slightly deformed, and deformed. LA-ICPMS U-Pb geochronology is performed on zircon separates of each subset. Our case study, involving the Permian Hongliuhe Formation in the southern Central Asian Orogenic Belt, analyzes each of the three clast subsets, as well as sandstone detrital samples, at three stratigraphic levels to yield a profile of the unroofed provenance. The age spectra of the clast samples exhibit different, wider distributions than sandstone samples, considered an effect of proximity to the respective provenance. Comparisons of clast data to sandstone data, as well as comparisons between stratigraphic levels, yield indications of key tectonic processes, in addition to the typical characteristics provided by detrital geochronology. The clast data indicates a minimal lag time, implying rapid exhumation rates, whereas sandstone data alone would indicate a 90 m.y. lag time. Early Paleozoic arc building episodes appear as Ordovician peaks in sandstone data, and Silurian-Devonian peaks in clast data, indicating a younging of magmatism towards the proximal provenance. A magmatic hiatus starts in the Devonian, correlating with the latest age of deformed clasts, interpreted as timing of collisional tectonics.

The new technologies in forestry, biomass processing and electrical generation through MHD, gas turbine, and steam turbine allows the implantation of agricultural and industrial conglomerates working in the scheme of cogeneration of electrical energy, vapor, chemical products, animal food and other products. The present work starts with the present cogeneration rules and analysis legal, administrative and financing aspects for the formation of industrial conglomerates in four levels: forestry companies (forestry and biomass residue); biomass processing companies (cellulignin and products from hemicellulosis hydro lysate); utility companies (electric energy, vapor, gases, water, etc.); and a consumer companies. Although it is possible that the conglomerate be operated by only one group it is shown that the nature of the enterprise points to the direction of a multi proprietary conglomerate of several incorporated companies. 3 refs

Full Text Available This study examined the policy evaluation of restructuring street vendors in Surakarta city. Street vendors represent the economic actors in the informal sector of urban economic activity. The government of City/District usually removes these street vendors by disguising this activity behind the reason of structuring, . The study used descriptive research with a qualitative approach. The relocation of street vendors in Surakarta City is orderly and smooth without violence which may impact badly on physic and material because the government of Surakarta City, especially Surakarta Mayor, uses persuasive approach. Notoharjo Market is a relocation place for street vendors at Banjarsari Monument Park. In the beginning, Notoharjo Market is crowded with buyers but current days, street vendors who occupy Notoharjo Market complain about lack of buyers. The lack of buyers at Notoharjo Market is because the facilities previously provided by the government of Surakarta City are not well maintained. The government of Surakarta City must listening all complains of street vendors for the smoothness and orderliness of trading activity of street vendors. Not only listening, but the government of Surakarta City also gives appropriate and best solution to street vendors such that street vendors feel comfort in selling and their income is better than before.

Integration of Jeddah Historical BIM and 3D GIS for Documentation and Restoration of Historical Monument

Directory of Open Access Journals (Sweden)

A. Baik

2015-08-01

Full Text Available This work outlines a new approach for the integration of 3D Building Information Modelling and the 3D Geographic Information System (GIS to provide semantically rich models, and to get the benefits from both systems to help document and analyse cultural heritage sites. Our proposed framework is based on the Jeddah Historical Building Information Modelling process (JHBIM. This JHBIM consists of a Hijazi Architectural Objects Library (HAOL that supports higher level of details (LoD while decreasing the time of modelling. The Hijazi Architectural Objects Library has been modelled based on the Islamic historical manuscripts and Hijazi architectural pattern books. Moreover, the HAOL is implemented using BIM software called Autodesk Revit. However, it is known that this BIM environment still has some limitations with the non-standard architectural objects. Hence, we propose to integrate the developed 3D JHBIM with 3D GIS for more advanced analysis. To do so, the JHBIM database is exported and semantically enriched with non-architectural information that is necessary for restoration and preservation of historical monuments. After that, this database is integrated with the 3D Model in the 3D GIS solution. At the end of this paper, we’ll illustrate our proposed framework by applying it to a Historical Building called Nasif Historical House in Jeddah. First of all, this building is scanned by the use of a Terrestrial Laser Scanner (TLS and Close Range Photogrammetry. Then, the 3D JHBIM based on the HOAL is designed on Revit Platform. Finally, this model is integrated to a 3D GIS solution through Autodesk InfraWorks. The shown analysis presented in this research highlights the importance of such integration especially for operational decisions and sharing the historical knowledge about Jeddah Historical City. Furthermore, one of the historical buildings in Old Jeddah, Nasif Historical House, was chosen as a test case for the project.

Full Text Available This paper makes a faunistic contribution to knowledge of spider composition in the xerothermic habitats of the Křéby National Nature Monument which is located in Kroměříž district, eastern Moravia. Spiders were collected by four different methods during 25 April–28 October 2013: pitfall traps, sweeping of herb vegetation, individual collecting and beating the branches of shrubs and trees. In total, 1070 individuals (865 adult spiders were collected and identified as 114 species of 19 families. The species diversity in the Křéby area is rather high, representing approximately 13% of Czech araneofauna. Of the identified species, five are listed in the Red List of Threatened Species in the Czech Republic. These included critically endangered Dysdera hungarica Kulczynski 1897, endangered Alopecosa solitaria (Herman, 1879, Cheiracanthium montanum (C. L. Koch, 1877 and vulnerable Lathys stigmatisata (Menge, 1869 and Haplodrassus dalmatensis (L. Koch, 1866. The findings of Alopecosa solitaria and Dysdera hungarica belong to the northernmost occurrence of these rare species in the Czech Republic. In general, the great richness of spider fauna and the occurrence of rare and threatened species for Czech region confirm the high biotic value of the investigated area. In addition, the author discussed management methods of the locality and suggest management conservation system for slowing down the succession rate on overgrown places.

Interstratified arkosic and volcanic rocks of the Miocene Spanish Canyon Formation, Alvord Mountain area, California: descriptions and interpretations

Science.gov (United States)

Buesch, David C.

2014-01-01

The Spanish Canyon Foundation in the Alvord Mountain area, California, varies from about 50 to 120 m thick and records the interstratification of arkosic sandstone and conglomerate with tuffaceous deposits and lava flows. In the lower third of the formation, arkosic sandstone and conglomerate are interstratified with tuffaceous deposits. Some tuffs might have been deposited as primary, nonwelded to partially welded ignimbrites or fallout tephra. Many of the tuffaceous deposits represent redeposited material that formed tuffaceous sandstone, and many of these deposits contain arkosic grains that represent mixing of different source matieral. Arkosic sandstone, and especially conglomerate (some with maximum clast lengths up to 1 m), represent intermittent incursions of coarser plutoniclastic fan deposits into other finer grained and mostly volcaniclastic basin deposits. After deposition of the 18.78 Ma Peach Spring Tuff, the amount of tuffaceous material decreased. The upper two-thirds of the formation has arkosic sandstone and conglomerate interstratified with two olivine basalt lave flows. locally, conglomerate clasts in this part of the section have maximum lengths up to 1 m. Many tuffaceous and arkosic sandstone beds of the Spanish Canyon Formation have tabular to broad (low-relief) lenticular geometry, and locally, some arkosic conglomerate fills channels as much as 1.5 m deep. These bedforms are consistent with deposition in medial to distal alluvial-fan or fluvial environments; some finer-grained deposits might have formed in lacustrine environments.

The construction of the Cistercian Monastery began at 1180, in an initial Late Romanesque style in which the Church was erected; later on, in 1258, the church underwent a severe fire, only the apse stood standing. The church was reconstructed at the end of the 13th century in Mudejar style. Gothic style was used later on, in the 16th century, for the reconstruction of the funerary chapel, and Renaissance style for the Plateresque door in between the church and the sacristy. At the end of the 16th century, the main door to access the church was built in Baroque style. In 1836, the Ecclesiastical Confiscations resulted on transfer the Monastery into particular owners. This fact favoured its abandon and ruin state until 1979, when architect Mariano Garcia Benito purchased the property and started the conservation and consolidation of the complex, beginning with the Bell Tower. Natural stone materials used in the Monastery are igneous (granite) and metamorphic rocks (gneiss and schist), and artificial stone materials are bricks and mortars, both joint and rendering ones. Granite is the most abundant material used in the complex, with a structural/reinforcing role in elements such as lintels, jambs, buttresses, or bottom areas of the walls with greater sizes and better dimensioned. Some pillars are granite built, from the large ashlars of the sacristy, to the rubble-work of the Mozarab chapel. Two types of monzogranite can be differentiated in relation to distinct constructive stages: the coarse texture monzogranite is used in the first building stages, while the fine texture monzogranite was employed mainly from 17th century on. Petrophysical characteristics of these granites are different but show a good quality to be used in construction. Nevertheless, the abandon and partial ruin of the complex, the devastating fire events (the second one in 1743) leaded to the decay acceleration of the monumental complex, being nowadays the church in ruin, with no roofs and walls

Do insurers respond to risk adjustment? A long-term, nationwide analysis from Switzerland.

Science.gov (United States)

von Wyl, Viktor; Beck, Konstantin

2016-03-01

Community rating in social health insurance calls for risk adjustment in order to eliminate incentives for risk selection. Swiss risk adjustment is known to be insufficient, and substantial risk selection incentives remain. This study develops five indicators to monitor residual risk selection. Three indicators target activities of conglomerates of insurers (with the same ownership), which steer enrollees into specific carriers based on applicants' risk profiles. As a proxy for their market power, those indicators estimate the amount of premium-, health care cost-, and risk-adjustment transfer variability that is attributable to conglomerates. Two additional indicators, derived from linear regression, describe the amount of residual cost differences between insurers that are not covered by risk adjustment. All indicators measuring conglomerate-based risk selection activities showed increases between 1996 and 2009, paralleling the establishment of new conglomerates. At their maxima in 2009, the indicator values imply that 56% of the net risk adjustment volume, 34% of premium variability, and 51% cost variability in the market were attributable to conglomerates. From 2010 onwards, all indicators decreased, coinciding with a pre-announced risk adjustment reform implemented in 2012. Likewise, the regression-based indicators suggest that the volume and variance of residual cost differences between insurers that are not equaled out by risk adjustment have decreased markedly since 2009 as a result of the latest reform. Our analysis demonstrates that risk-selection, especially by conglomerates, is a real phenomenon in Switzerland. However, insurers seem to have reduced risk selection activities to optimize their losses and gains from the latest risk adjustment reform.

Thermoluminescence applied to uranium exploration and genesis of the Westmoreland uranium deposits - implications for the Northern Territory

International Nuclear Information System (INIS)

Hochman, M.B.M.; Ypma, P.J.M.

1984-01-01

The Westmoreland uranium deposits occur on the northern flank of the Murphy Tectonic Ridge in the upper member of the Westmoreland Conglomerate. Uranium mineralisation is spatially associated with the contact of the overlying basaltic Siegal Volcanics and the margins of intrusive dolerite dykes which are geochemically similar to the Siegal Volcanics. Thermoluminescence measurements on 800 samples from within the orebodies and surrounding host rock have indicated that all of the Westmoreland Conglomerate has suffered major radiation damage attributable to at least 10 ppm uranium over 10 9 years. The underlying rhyolitic Mid Proterozoic Cliffdale Volcanics have distinctive TL glow curves indicative of radiation sensitisation caused by high uranium contents. These volcanics are part of the Mid Proterozoic volcanic event known to be enriched in uranium. The Westmoreland Conglomerate has been derived by erosion of the uranium-rich Cliffdale Volcanics and associated Nicholson Granite Complex which makes it likely that the Westmoreland Conglomerate had a high inherent uranium content. It is proposed that this precontained uranium within the Westmoreland Conglomerate was remobilized in a convective cell system possibly triggered by intrusion of dolerite dykes, or by a later rejuvenation of vertical structures which provided an ascending heat flow. Pitchblende was precipitated where suitable reducing conditions existed close to the basic volcanics and dykes

Staryi Krym and Its Monuments through the Eyes of the Travelers of the late 18th – early 19th centuries

Directory of Open Access Journals (Sweden)

Khrapunov N.I.

2016-12-01

Full Text Available Research objective: This article addresses the accounts on Staryi Krym, a town in the Crimean Peninsula, supplied by travelogues written after the joining of the region to Russia. Research materials: Modern archaeolgoists can use these textual and visual accounts as a source of information on the condition of Moslem monuments, which were later damaged by anthropogenic and natural factors, and science historians can draw conclusions on the features of discoverying and interpretation of Moslem history and “Oriental” architecture in the period of the Enlightenment. The travelogues developed a multi-dimensional image of Staryi Krym. Abandoned and collapsing Moslem town, a living illustration from the outgoing age, with still standing ancient mosques, baths, fortifications, and graves, got virtual connections with classic past of the Crimea, finding itself to be a “heir” of one or another settlement documented by Greco-Roman geographers. Research results and novelty: Through the travellers’ eyes, Staryi Krym, by images of the Cimmerians and the Cimbrians, got a key role in the history of Crimean Peninsula, and even supplied it with the name of Crimea, which connected the “noble barbarians” of antiquity with the “modern Celts” – the Frenchs and the Scots, and the Past of Europe with its Present. Staryi Krym became a component of literatural discourse, allowing the classics of the Sentimentalism to think of the frailty of earthly life. This town also became a subject of painting, which made it a part of romantic appearance of Taurica.

The auriferous placer at Mount Robert, Pietersburg Greenstone belt

International Nuclear Information System (INIS)

Saager, R.; Muff, R.

1986-01-01

The Mount Robert gold placer near Potgietersrus occurs in coarse, matrix-supported conglomerates of the Uitkyk Formation within the Pietersburg greenstone belt. Sedimentological and mineralogical investigations indicate that the conglomerates and the ore minerals were derived from a greenstone provenance, and that they were deposited in a braided river environment within a rapidly subsiding trough. Lack of sedimentological concentration of the heavy minerals is considered to be the main reason for the low and erratic gold grades encountered (usually below 1 g/t) and, thus, the failure of all past mining ventures. The mineralogical composition of the Mount Robert ore closely resembles that of the Witwatersrand deposits. However, uraninite is absent, probably as a result of its complete removal by weathering processes. Remaining small uranium concentrations can still be detected within the conglomerates where they occur associated with grains of carbonaceous matter, leucoxene aggregates, and secondary iron-hydroxides. U3O8 values found in the conglomerates are given

Surveying a monumental building damaged by the earthquake means to analyse its geometries, the structural elements, the connection still exist between the different parts, in order to define its state of conservation, to make structural analysis and to plan a proper project of restoration, consolidation, seismic improvement or addition of new elements. The survey of structural geometry represents the first necessary moment of building' knowledge investigation, to be performed after the securing of the building by the Firefighters or Civil Protection. How and by which instruments the geometric analysis are conducted depends on many factors, not always exclusively on the will of the experts involved in the restoration project, but more often dictated by political, technical, social or economic needs. The accurate geometrical survey is referred as fundamental operation even by national Directive for evaluation and earthquake risk reduction of cultural heritage (GU n. 24 - 29/01/2008 and 2011 updates), which defines guidelines for preventive interventions on built heritage in order to make the structures less vulnerable in case of earthquake. Nowadays, the wide use of tools and accurate surveying techniques makes it possible to achieve an adequate level of accuracy of information related to the buildings, overcoming the difficulties due to accessibility of the damaged structures. The geometrical survey of the Basilica of Santa Maria di Collemaggio in L'Aquila, was made by Politecnico di Milano starting from 2013, within the project "Ripartire da Collemaggio" (http://www.ungiornoacollemaggio.it/content/2027), financed by Eniservizi.

In 2011, a large magnitude flow release from Flaming Gorge Reservoir, Wyoming and Utah, occurred in response to high snowpack in the middle Rocky Mountains. This was the third highest recorded discharge along the Green River downstream of Flaming Gorge Dam, Utah, since its initial closure in November 1962 and motivated a research effort to document effects of these flows on channel morphology and sedimentology at four long-term monitoring sites within the Canyon of Lodore in Dinosaur National Monument, Colorado and Utah. Data collected in September 2011 included raft-based bathymetric surveys, ground-based surveys of banks, channel cross sections and vegetation-plot locations, sand-bar stratigraphy, and painted rock recovery on gravel bars. As part of this surveying effort, Global Navigation Satellite System (GNSS) data were collected at benchmarks on the canyon rim and along the river corridor to establish a high-resolution survey control network. This survey control network allows for the collection of repeatable spatial and elevation data necessary for high accuracy geomorphic change detection. Nearly 10,000 ground survey points and more than 20,000 bathymetric points (at 1-meter resolution) were collected over a 5-day field campaign, allowing for the construction of reach-scale digital elevation models (DEMs). Additionally, we evaluated long-term geomorphic change at these sites using repeat topographic surveys of eight monumented cross sections at each of the four sites. Analysis of DEMs and channel cross sections show a spatially variable pattern of erosion and deposition, both within and between reaches. As much as 5 meters of scour occurred in pools downstream from flow constrictions, especially in channel segments where gravel bars were absent. By contrast, some channel cross sections were stable during the 2011 floods, and have shown almost no change in over a decade of monitoring. Partial mobility of gravel bars occurred, and although in some locations

Klapa, Przemyslaw; Mitka, Bartosz; Zygmunt, Mariusz

2017-12-01

The terrestrial laser scanning technology has a wide spectrum of applications, from land surveying, civil engineering and architecture to archaeology. The technology is capable of obtaining, in a short time, accurate coordinates of points which represent the surface of objects. Scanning of buildings is therefore a process which ensures obtaining information on all structural elements a building. The result is a point cloud consisting of millions of elements which are a perfect source of information on the object and its surrounding. The photogrammetric techniques allow documenting an object in high resolution in the form of orthophoto plans, or are a basis to develop 2D documentation or obtain point clouds for objects and 3D modelling. Integration of photogrammetric data and TLS brings a new quality in surveying historic monuments. Historic monuments play an important cultural and historical role. Centuries-old buildings require constant renovation and preservation of their structural and visual invariability while maintaining safety of people who use them. The full process of surveying allows evaluating the actual condition of monuments and planning repairs and renovations. Huge sizes and specific types of historic monuments cause problems in obtaining reliable and full information on them. The TLS technology allows obtaining such information in a short time and is non-invasive. A point cloud is not only a basis for developing architectural and construction documentation or evaluation of actual condition of a building. It also is a real visualization of monuments and their entire environment. The saved image of object surface can be presented at any time and place. A cyclical TLS survey of historic monuments allows detecting structural changes and evaluating damage and changes that cause deformation of monument’s components. The paper presents application of integrated photogrammetric data and TLS illustrated on an example of historic monuments from southern

1982-07-01

On eastern Axel Heiberg Island erosional outliers of the Miocene-early Pliocene Beaufort Formation overlie with angular unconformity, or are faulted against, Mesozoic and early Tertiary strata East of Princess Margaret Arch the Beaufort Formation is divisible into three lithofacies: a conglomerate lithofacies interpreted as alluvial-plain deposits, a sandstone conglomerate lithofacies interpreted as distal alluvial-fan deposits and a sandstone-mudstone-siltstone lithofacies interpreted as alluvial-plain deposits. The floodplain was vegetated by a coniferous forest which was characterized by Picea banksii, Larix, Metasequoia and Alnus. Paleocurrent analysis, facies relationships and petrology of the conglomerates and sandstones indicate the provenance of the Beaufort Formation wa Mesozoic strata to the west. Deposition of the Beaufort Formation on eastern Axel Heiberg Island clearly postdates folding of mid-Eocene and older strata and thus provides a minimum age for orogenesis in this part of the Arctic.

Full Text Available Financial conglomerates are financial institutions that provide all forms of financial services on the top of ordinary banking service. The quality of financial conglomerates’ performance depends on number of factors namely ownership structure, internal capital market and resources sharing. Research on the performance of financial conglomerates are still lacking in Indonesia. This study, therefore, is among the first attempt to assess the influence of ownership structure, internal capital market and resources sharing on the performance financial conglomerate firms in Indonesia, from the industrial organizational theory perspectives. The methodology employed is the ex-post facto research design, using secondary data. The population of the study is all the conglomerates firms listed on the Indonesian Stock Exchange between 2010 until 2015 persistently. The study used regression as a tool of analysis. Findings supported three out of the five hypotheses proposed. Efficient subsidy and managerial ownership had no significant influence on firms’ performance. Efficient transfer segment had positive influence on firms’ performance. Similarly, result supported the proposition that intangible and tangible resources had positive effect on firms’ performance.

Gypsum (CaSO4·2H2O) has been identified as a major component of part of Olympia Undae in the northern polar region of Mars, along with the mafic minerals more typical of Martian dune fields. The source and age of the gypsum is disputed, with the proposed explanations having vastly different implications for Mars' geological history. Furthermore, the transport of low density gypsum grains relative to and concurrently with denser grains has yet to be investigated in an aeolian setting. To address this knowledge gap, we performed a field study at White Sands National Monument (WSNM) in New Mexico, USA. Although gypsum dominates the bulk of the dune field, a dolomite-rich [CaMg(CO3)2] transport pathway along the northern border of WSNM provides a suitable analog site to study the transport of gypsum grains relative to the somewhat harder and denser carbonate grains. We collected samples along the stoss slope of a dune and on two coarse-grained ripples at the upwind margin of the dune field where minerals other than gypsum were most common. For comparison, additional samples were taken along the stoss slope of a dune outside the dolomite transport pathway, in the center of the dune field. Visible and near-infrared (VNIR), X-ray powder diffraction (XRD), and Raman analyses of different sample size fractions reveal that dolomite is only prevalent in grains larger than ∼1 mm. Other minerals, most notably calcite, are also present in smaller quantities among the coarse grains. The abundance of these coarse grains, relative to gypsum grains of the same size, drops off sharply at the upwind margin of the dune field. In contrast, gypsum dominated the finer fraction (MCD) are consistent with the observed concentration of gypsum at dune crests. Density-driven differentiation in transport should not influence sediment fluxes of finer grains (<1 mm) as strongly on Earth, suggesting that the high ratio of fine gypsum grains to other minerals at WSNM is caused by a relatively

This study is part of the United States Department of Energy's National Uranium Resource Evaluation Program to understand the geologic setting, amount, and availability of uranium resources within the boundaries of the United States. The systematic study of Precambrian quartz-pebble conglomerates and areas that may contain such conglomerates is an integral part of DOE's resource evaluation program, because deposits of world-wide importance occur in such terrains in Canada and South Africa, and because terrains similar to those producing uranium from quartz-pebble conglomerates exist elsewhere in the United States. Because of the ready availability of Tertiary sandstone and Colorado Plateau-type uranium deposits, large areas of Precambrian rocks in the US have not been fully assessed for uranium potential. Thus, the Uinta Arch Project was undertaken to assess the favorability of Precambrian metasedimentary rocks in northern Utah for deposits of uranium in Precambrian quartz-pebble conglomerates. Rocks of interest to this study are the thick, clastic sequences within the Uinta Arch that are considered to be of Early Proterozoic age. The Uinta Arch area is known to contain rocks which generally fit the lithologic characteristics that are understood to limit the occurrence of Precambrian fossil placers. However, detailed geology of these rocks and their exact fit to the model described for uraniferous conglomerates was not known. The primary goal of the Uinta Arch Project was to determine how well these Precambrian rocks resemble known deposits and to describe the favorability of placer uranium deposits

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

2017-06-01

Full Text Available The Archaean granitoid pluton of the Singhbhum craton in E India is overlain by Archaean to Palaeoproterozoic metasediments. These sediments are still poorly known and their stratigraphy is under debate. Several scattered, most probably Meso- to Neoarchaean, conglomerates are present in the state of Jharkhand that differ so much in characteristics that they are probably not related to each other. The sedimentology of a series of conglomerate patches and layers near Bhurkuli has been investigated, including the characteristics of the clasts. It is deduced on the basis of these characteristics and the sedimentological context that the Bhurkuli conglomerates represent the channel facies of a river system that differed from the types of fluvial systems that exist nowadays.

Conservation of Monuments by a Three-Layered Compatible Treatment of TEOS-Nano-Calcium Oxalate Consolidant and TEOS-PDMS-TiO2 Hydrophobic/Photoactive Hybrid Nanomaterials

Directory of Open Access Journals (Sweden)

Chrysi Kapridaki

2018-04-01

Full Text Available In the conservation of monuments, research on innovative nanocomposites with strengthening, hydrophobic and self-cleaning properties have attracted the interest of the scientific community and promising results have been obtained as a result. In this study, stemming from the need for the compatibility of treatments in terms of nanocomposite/substrate, a three-layered compatible treatment providing strengthening, hydrophobic, and self-cleaning properties is proposed. This conservation approach was implemented treating lithotypes and mortars of different porosity and petrographic characteristics with a three-layered treatment comprising: (a a consolidant, tetraethoxysilane (TEOS-nano-Calcium Oxalate; (b a hydrophobic layer of TEOS-polydimethylsiloxane (PDMS; and (c a self-cleaning layer of TiO2 nanoparticles from titanium tetra-isopropoxide with oxalic acid as hole-scavenger. After the three-layered treatment, the surface hydrophobicity was improved due to PDMS and nano-TiO2 in the interface substrate/atmosphere, as proven by the homogeneity and the Si–O–Ti hetero-linkages of the blend protective/self-cleaning layers observed by Scanning Electron Microscope (SEM, Transmission Electron Microscope (TEM and Fourier-Transform Infrared Spectroscopy (FTIR. The aesthetic, microstructural, mechanical and permeabile compatibility of the majority of treated substrates ranged within acceptability limits. The improved photocatalytic activity, as proven by the total discoloration of methylene blue in the majority of cases, was attributed to the anchorage of TiO2, through the Si–O–Ti bonds to SiO2, in the interface with the atmosphere, thus enhancing photoactivation.

Evaluation of the potential for debris and hyperconcentrated flows in Capulin Canyon as a result of the 1996 Dome fire, Bandelier National Monument, New Mexico

Science.gov (United States)

Cannon, Susan H.

1997-01-01

The Dome fire of April 1996 burned 6684 ha in Bandelier National Monument and the adjacent Sante Fe National Forest. The potential for significant debris- and hyperconcentrated-flow activity in Capulin Canyon is evaluated through 1) a systematic consideration of geologic and geomorphic factors that characterize the condition of the hillslope materials and channels following the fire, 2) examination of sedimentologic evidence for past debris-flow activity in the canyon, and 3) evaluation of the response of the watershed through the 1996 summer monsoon season. The lack of accumulations of dry-ravel material on the hillslopes or in channels, the absence of a continuous hydrophobic layer, the relatively intact condition of the riparian vegetation and of the fibrous root mat on the hillslopes, and the lack of evidence of widespread past debris- and hyperconcentrated-flow activity, even with evidence of past fires, indicate a low potential for debris-flow activity in Capulin Canyon. In addition, thunderstorms during the summer monsoon of 1996 resulted in abundant surface overland flow on the hillslopes which transported low-density pumice, charcoal, ash and some mineral soil downslope as small-scale and non-erosive debris flows. In some places cobble- and boulder-sized material was moved short distances. A moderate potential for debris- and hyperconcentrated-flow activity is identified for the two major tributary canyons to Capulin Canyon based on evidence of both summer of 1996 and possible historic significant debris-flow activity.

2014 marked the sixth and most widespread mass bleaching event reported in the Northwestern Hawaiian Islands, home to the Papahānaumokuākea Marine National Monument (PMNM), the world's second largest marine reserve. This event was associated with an unusual basin-scale warming in the North Pacific Ocean, with an unprecedented peak intensity of around 20°C-weeks of cumulative heat stress at Lisianksi Island. In situ bleaching surveys and satellite data were used to evaluate the relative importance of potential drivers of bleaching patterns in 2014, assess the subsequent morality and its effects on coral communities and 3D complexity, test for signs of regional acclimation, and investigate long-term change in heat stress in PMNM. Surveys conducted at four island/atoll (French Frigate Shoals, Lisianski Island, Pearl and Hermes Atoll, and Midway Atoll) showed that in 2014, percent bleaching varied considerably between islands/atolls and habitats (back reef/fore reef and depth), and was up to 91% in shallow habitats at Lisianski. The percent bleaching during the 2014 event was best explained by a combination of duration of heat stress measured by Coral Reef Watch's satellite Degree Heating Week, relative community susceptibility (bleaching susceptibility score of each taxon * the taxon's abundance relative to the total number of colonies), depth and region. Mean coral cover at permanent Lisianski monitoring sites decreased by 68% due to severe losses of Montipora dilatata complex, resulting in rapid reductions in habitat complexity. Spatial distribution of the 2014 bleaching was significantly different from the 2002 and 2004 bleaching events likely due to a combination of differences in heat stress and local acclimatization. Historical satellite data demonstrated heat stress in 2014 was unlike any previous event and that the exposure of corals to the bleaching-level heat stress has increased significantly in the northern PMNM since 1982, highlighting the increasing

Non destructive testing has been gaining a large interest in the field of the diagnostics applied to the cultural heritage. The exceptional and brittle nature of the investigated structures, in fact, discourages invasive investigation techniques even more than in other applications. In particular, non-destructive testing can be exploited for the detection of fractures or for the investigation of pillars and columns within churches of particular historical and/or architectural relevance. This has been recently done in the cathedral of Matera [1], and previously in the crypt of the Romanesque cathedral of Otranto [2]. In both cases, integrated prospecting has been performed, where GPR data have been considered together with acoustic sounding or resistive measurements and even microclimatic investigation. Integrated prospecting is a good help to perform not only the diagnosis of the structure but also its restoring and continuative preservation. In this contribution, we propose a case study where integrated methodologies have been adopted for the analysis of the conservation state of the architectural elements which constitute the church of S.Giovanni al Sepolcro, in Brindisi (Southern Italy). This church is a precious artifact of medieval age, which recently underwent restoration works. IBAM-CNR has been put in charge of the task to analyse the constitutive materials, the superficial finishing (paintings, patinas, plasters etc.) and the causes and the products of the decay. The information retrieved from the analysis of the materials have been fruitfully integrated with non-destructive testing of the structure. Some results will be shown at the conference.

In this work, the "hi-tech" complex biocleaning and restoration of the 14th-century fresco Triumph of Death (5.6x15.0 m) at the Camposanto Monumental Cemetery (Pisa, Italy) is reported. Since 2000, the restoration based on the biological cleaning of noble medieval frescoes, has been successfully utilized in this site. The novelty of this study is the 2-steps biocleaning process using Pseudomonas stutzeri A29 viable cells, previously applied for recovering other valuable frescoes. In this case, after the fresco detachment from the asbestos-cement support (eternity), both the animal glue and the residues of calcium caseinate were biologically removed respectively from the front and from the back of the fresco in 3 hours as indicated by GC-MS and PY/GC-MS analyses. The data obtained during the monitoring of the bio-restoration process confirmed that the adopted procedure does not leave residual cells on the fresco surfaces as showed by plate count method, ATP determination and also SEM observation. In addition, to avoid the risk of condensation phenomena after the relocation of the restored fresco sections onto the original walls, the use of a new support has been set up together with the design of a control system that allows a continuous monitoring of environmental parameters for prevention and conservation purposes. This large-scale biorestoration work clearly shows and confirms that this biotechnology is highly efficient, safe, non-invasive, risk-free and very competitive compared to the traditional cleaning methods, offering an unusual "resurrection" of the degraded artworks also in very complicated and delicate conditions such as the Triumph of Death fresco, defined for its dimension and artistic importance the 'Pisa's Sistina frescoes'. These findings can be of significant importance for other future new restoration activities and they are crucial for determining preservation strategies in this field.

Soil Sampling to Demonstrate Compliance with Department of Energy Radiological Clearance Requirements for the ALE Unit of the Hanford Reach National Monument

Fritz, Brad G.; Dirkes, Roger L.; Napier, Bruce A.

2007-04-01

The Hanford Reach National Monument consists of several units, one of which is the Fitzner/Eberhardt Arid Lands Ecology Reserve (ALE) Unit. This unit is approximately 311 km2 of shrub-steppe habitat located to the south and west of Highway 240. To fulfill internal U. S. Department of Energy (DOE) requirements prior to any radiological clearance of land, DOE must evaluate the potential for residual radioactive contamination on this land and determine compliance with the requirements of DOE Order 5400.5. Historical soil monitoring conducted on ALE indicated soil concentrations of radionuclides were well below the Authorized Limits. However, the historical sampling was done at a limited number of sampling locations. Therefore, additional soil sampling was conducted to determine if the concentrations of radionuclides in soil on the ALE Unit were below the Authorized Limits. This report contains the results of 50 additional soil samples. The 50 soil samples collected from the ALE Unit all had concentrations of radionuclides far below the Authorized Limits. The average concentrations for all detectable radionuclides were less than the estimated Hanford Site background. Furthermore, the maximum observed soil concentrations for the radionuclides included in the Authorized Limits would result in a potential annual dose of 0.14 mrem assuming the most probable use scenario, a recreational visitor. This potential dose is well below the DOE 100-mrem per year dose limit for a member of the public. Spatial analysis of the results indicated no observable statistically significant differences between radionuclide concentrations across the ALE Unit. Furthermore, the results of the biota dose assessment screen, which used the ResRad Biota code, indicated that the concentrations of radionuclides in ALE Unit soil pose no significant health risk to biota.

Full Text Available The aim of this paper is to consider the actions of street art and urban recolouring on the monuments of communist dictatorship, which have not been demolished after the fall of the Berlin Wall in 1989. Such rewriting actions have converted these monuments in spaces of artistic disputes in stark contrast with the memory conveyed by the communist regime. My goal is to understand the semiotic logic that characterizes the art of protest on the dictatorship monuments. In addition, with the analysis of three specific monuments I will investigate the relationship between imaginary and iconoclasm with the purpose of defining a new form of "attack on image" which is not only aimed at the destruction but also at the creation of new imaginaries.

To mitigate the damage effects of earthquakes in urban areas and particularly in historical centres prone to high seismic hazard is an important task to be pursued. As a matter of fact, seismic history throughout the world informs us that earthquakes have caused deep changes in the ancient urban conglomerations due to their high building vulnerability. Furthermore, some quarters can be exposed to an increase of seismic actions if compared with adjacent areas due to the geological and/or topographical features of the site on which the historical centres lie. Usually, the strategies aimed to estimate the local seismic hazard make only use of the geological-geophysical surveys. Thorough this approach we do not draw any lesson from what happened as a consequences of past earthquakes. With this in mind, we present the results of a joined use of historical data and traditional geological-geophysical approach to analyse the effects of possible future earthquakes in historical centres. The research activity discussed here is arranged into a joint collaboration between the Department of Civil Protection of the Presidency of Council of Ministers, the Institute of Environmental Geology and Geoengineering and the Institute of Archaeological and Monumental Heritage of the National (Italian) Research Council. In order to show the results, we discuss the preliminary achievements of the integrated study carried out on two historical towns located in Southern Apennines, a portion of the Italian peninsula exposed to high seismic hazard. Taking advantage from these two test sites, we also discuss some methodological implications that could be taken as a reference in the seismic microzonation studies.

An altar in honor of the anatomical gift.

On All Saints Day 2009 a monument for body donors was unveiled by the Department of Anatomy, at the Radboud University Nijmegen Medical Centre (RUNMC). Although body donation to medical science contributes substantially to the quality of medical education, the ceremony was only the first time that the RUNMC publicly reciprocated the anatomical gift. By means of the monument the department of Anatomy endeavors to express gratitude for the gift of body donors and raise awareness among students to value the gift and treat donor bodies with the proper respect. Furthermore, the large attendance of bereaved at the unveiling ceremony, revealed another equally important meaning of the monument, which is the significance of the monument to the donor kin. The wish of a body donor has large implications for the way bereaved can take leave of the donor; there is limited time to bade the deceased farewell, the body will not be available for a funeral, and the donor kin stay behind empty handed without even a grave or ashes. Therefore the monument can be meaningful by facilitating the bereaved with a place of commemoration. The design of the monument anticipates on these multiple meanings and symbolisms by placing an old marble dissection table in the shape of an altar and fixing a bronze sculpture of a phoenix as symbol of imperishableness.

Oligocene-Miocene burial and exhumation of the southernmost Gangdese mountains from sedimentary and thermochronological evidence

The Kailas conglomerates crop out ubiquitously along the southernmost boundary of the Gangdese batholith. They unconformably overlie the Gangdese batholith and are displaced by the Great Counter thrust (GCT) fault, forming a fault contact with the Xigaze forearc basin, the associated subduction complex and the Tethyan Himalayan sequence. These strata furnish a record of uplift and paleoenvironmental change in the Indus-Yarlung suture zone during the Oligocene-Miocene. Our new and previously published low-temperature thermochronometric data from the Gangdese batholith and the Kailas conglomerates indicate a period of rapid exhumation beginning approximately 17-15 Ma centered on the southern margin of the Gangdese batholith, whereas regional uplift commenced significantly earlier during the deposition of the Kailas conglomerates, based on the presence of an abrupt facies transition from deep-water lacustrine deposits to red alluvial fan or fluvial deposits. The period of rapid exhumation probably lagged behind the initiation of faster uplift, while the related changes in the depositional environment were most likely recorded immediately in the basin stratigraphy. Subsequently, the Kailas conglomerates were buried in association with the development of the north-directed Great Counter thrust, while rapid exhumation was facilitated by efficient incision by the paleo-Yarlung river at approximately 17-15 Ma.

Hybrid intermediaries

I introduce the concept of hybrid intermediaries: financial conglomerates that control a multiplicity of entity types active in the "assembly line" process of modern financial intermediation, a system that has become known as shadow banking. The complex bank holding companies of today are the best example of hybrid intermediaries, but I argue that financial firms from the "nonbank" space can just as easily evolve into conglomerates with similar organizational structure, thus acquiring the cap...

Basaltic caves at Craters of the Moon National Monument and Preserve as analogs for Mars

Science.gov (United States)

Hinman, N. W.; Richardson, C. D.; McHenry, L.; Scott, J. R.

2010-12-01

Basaltic caves and lava tubes offer stable physicochemical conditions for formation of secondary minerals. Such features, putatively observed on Mars, intercept groundwater to weather country rock, leading to formation of secondary minerals. Further, caves are stable environments to search for evidence of past life, as they could offer protection from the oxidizing martian atmosphere. Searching for signs of life in a cave that could protect bio/organic compounds would preclude the need for risky drilling on Mars. Craters of the Moon National Monument (COM) offers an opportunity to study caves in Holocene iron-rich basalt flows to characterize secondary mineral deposits and search for organic compounds associated with secondary minerals; COM basalts are a good analog for martian basalts because of their high iron but other elements are higher at COM than on Mars. The Blue Dragon flow (~2.1 ka) contains the majority of the accessible caves and lava tubes. Two types of secondary mineral deposits were observed in these caves: ceiling coatings and crack or floor precipitates. Hematite, silica, and calcite comprise ceiling coatings. The crack and floor precipitates are white, efflorescent deposits in cavities along cave walls and ceilings or in localized mounds on cave floors. The secondary minerals in crack and floor precipitates are mainly thenardite and mirabilite with some minor concentrations of trona and/or burkeite. Organic compounds were found associated with the efflorescent deposits. Formation of the deposits is likely due to chemical leaching of basalt by meteoritic water. To test this, fluids collected from the ceiling and walls of the caves were analyzed. Solutions were modeled with the geochemical code, PHREEQC. The model tracked composition as water evaporated. Selected minerals were allowed to precipitate as they became oversaturated. Among the first minerals to become oversaturated were quartz and calcite, which are observed in ceiling deposits. Iron

The Ecology of Parasite-Host Interactions at Montezuma Well National Monument, Arizona - Appreciating the Importance of Parasites

Science.gov (United States)

O'Brien, Chris; van Riper, Charles

2009-01-01

Although parasites play important ecological roles through the direct interactions they have with their hosts, historically that fact has been underappreciated. Today, scientists have a growing appreciation of the scope of such impacts. Parasites have been reported to dominate food webs, alter predator-prey relationships, act as ecosystem engineers, and alter community structure. In spite of this growing awareness in the scientific community, parasites are still often neglected in the consideration of the management and conservation of resources and ecosystems. Given that at least half of the organisms on earth are probably parasitic, it should be evident that the ecological functions of parasites warrant greater attention. In this report, we explore different aspects of parasite-host relationships found at a desert spring pond within Montezuma Well National Monument, Arizona. In three separate but related chapters, we explore interactions between a novel amphipod host and two parasites. First, we identify how host behavior responds to this association and how this association affects interactions with both invertebrate non-host predators and a vertebrate host predator. Second, we look at the human dimension, investigating how human recreation can indirectly affect patterns of disease by altering patterns of vertebrate host space use. Finally - because parasites and diseases are of increasing importance in the management of wildlife species, especially those that are imperiled or of management concern - the third chapter argues that research would benefit from increased attention to the statistical analysis of wildlife disease studies. This report also explores issues of statistical parasitology, providing information that may better inform those designing research projects and analyzing data from studies of wildlife disease. In investigating the nature of parasite-host interactions, the role that relationships play in ecological communities, and how human

Gold-bearing fluvial and associated tidal marine sediments of Proterozoic age in the Mporokoso Basin, northern Zambia

Science.gov (United States)

Andrews-Speed, C. P.

1986-07-01

The structurally defined Mporokoso Basin contains up to 5000 m of continental and marine clastic sediments and minor silicic volcanics which together form the Mporokoso Group. These rocks overlie unconformably a basement of silicic-intermediate igneous rocks and accumulated within the interval 1830-1130 Ma. This sedimentological study was restricted to the eastern end of the basin and was part of an assessment of the potential for palaeoplacer gold in the Mporokoso Group. At the base of the Mporokoso Group, the Mbala Formation consists of 1000-1500 m of purple sandstones and conglomerates deposited in a braided-stream system overlain by 500-1000 m of mature quartz arenites deposited in a tidal marine setting. A general coarsening-upward trend exists within the fluvial sediments. Sandy, distal braided-stream facies passes upwards into more proximal conglomeratic facies. In proximal sections, poorly sorted conglomerates form the top of the coarsening-up sequence which is 500-700 m thick. The overlying fluvial sediments fine upwards. The tidal marine sandstones at the top of the Mbala Formation resulted from reworking of fluvial sediments during a marine transgression. Well-exposed sections with fluvial conglomerates were studied in detail. Individual conglomerate bodies form sheets extending for hundreds of metres downstream and at least one hundred metres across stream, with little sign of deep scouring or channelling. They are generally matrix-supported. The whole fluvial sequence is characterised by a paucity of mud or silt. These conglomerates were deposited by large velocity, sheet flows of water which transported a bed-load of pebbles and sand. Most fine material settling out from suspension was eroded by the next flow. The great lateral and vertical extent and the uniformity of the fluvial sediments suggest that the sediments accumulated over an unconfined alluvial plain and that the tectonic evolution of the source area was relatively continuous and not

Full Text Available Karin Bohr focuses on the practical dealing with the history of our region. The work „Entstehung des Denkmalschutz- und pflegegesetzes in Rheinland-Pfalz“ features an account of the history of the protection of historical monuments dating back to the end of the 19th century. Furthermore, it highlights the superior goals and legal aspects of the topic.The preservation of structural remains as important historical sources has been the responsibility of the DNK (Deutschen Nationalkomitee für Denkmalschutz since 1973. In detail it is a federal issue.Especially in the Rhineland region, numerous bills have been passed concerning the correct treatment of historical monuments as well as structural remains. In the course of time, the resident population increasingly supported the enforcement of these laws themselves. The bill concerning the protection of monuments of 1978 can be seen as a milestone in the history of monument protection in Rhineland-Palatinate. It regulated the protection of cultural values in detail and gave the protection of historical monuments an important role in daily life and politics, which it maintains until the present day.

Uranium minerals in Upper Carboniferous rocks in the Nowa Ruda region

International Nuclear Information System (INIS)

Bareja, E.

1981-01-01

Results of mineralogical studies on uranium in Upper Carboniferous rocks (Glinik Beds - Westphalian C - D and Ludwikowice Beds - Stephanian) in the vicinities of Nowa Ruda (Central Sudetic Depression) are presented. Uranium mineralization is here related to sandstones and polymictic conglomerates with clay and clay-carbonate cement. The major uranium-bearing horizon was found in middle part of the Glinik Beds, and some increase in uranium content - at the base of that unit. In the case of Stephanian rocks, points with uranium mineralization were found in various parts of the Ludwikowice Beds sequence: in basal conglomerate horizon and platy sandstones. Uranium minerals mainly occur in cement of sandstones and conglomerates. They were mainly identified as uranium blende and minerals of the sulfate group - zippeite and uranopilite. Mineralized uranium-bearing horizons display mineral paragenesis typical of Upper Carboniferous rocks of the Central Sudetic Depression: uranium blende, pyrite, chalcopyrite, sphalerite and galena.

Idaho's Eastern Snake River Plain (ESRP) is host to extensive expressions of basaltic volcanism dominated by non evolved olivine tholeiites (NEOT) with localized occurrences of evolved lavas. Craters of the Moon National Monument (COTM) is a polygenetic lava field comprised of more than 60 lava flows emplaced during 8 eruptive periods spanning the last 15 kyrs. The most recent eruptive period (period A; 2500-2000 yr B.P.) produced flows with total alkali vs. silica classifications spanning basalt to trachyte. Coeval with the emplacement of the COTM period A volcanic pile was the emplacement of the Wapi and King's Bowl NEOT 70 km SSE of COTM along the Great Rift. Previous investigations have determined a genetic link between these two compositionally distinct volcanic centers where COTM compositions can be generated from NEOT melts through complex ascent paths and variable degrees of fractionation and assimilation of lower-middle crustal materials. The Mars Exploration Rover, Spirit, conducted a robotic investigation of Gusev crater from 2004-2010. Spirit was equipped with the Athena science payload enabling the determination of mineralogy (mini-Thermal Emission Spectrometer, Pancam multispectral camera, and Mössbauer spectrometer), bulk chemistry (Alpha Particle X-ray Spectrometer) and context (Pancam and Microscopic Imager). During sol 32 Spirit investigated an olivine basalt named Adirondack, the type specimen for a class of rock that composes much of the plains material within Gusev Crater and embays the Columbia Hills. Following the characterization of the plains material, Spirit departed the plains targeting the Columbia Hills and ascending at Husband Hill. During Spirit's ascent of Husband Hill three additional classes of volcanic rock were identified as distinct by their mini-TES spectra; Wishstone, Backstay and Irvine. These rocks are classified as tephrite, trachy-basalt and basalt, respectively, and are the first alkaline rocks observed on Mars. These

The Paleozoic-Mesozoic recycling of the Rakaia Terrane, South Island, New Zealand : sandstone clast and sandstone petrology, geochemistry, and geochronology

The Torlesse terranes - part of the New Zealand Eastern Province - are accretionary complexes that comprise an enormous volume of quartzofeldspathic sandstones and mudstones with subsidiary conglomerates plus minor oceanic assemblages. Two terranes are recognised in the South Island - the Permian to Late Triassic Rakaia Terrane and the Late Jurassic to Early Cretaceous Pahau Terrane. Sandstone clasts from two Rakaia Terrane and two Pahau Terrane conglomerates were collected. We present the first combined detailed information on petrography and geochemistry of Torlesse conglomerate sandstone clasts and use our own and published U-Pb SHRIMP detrital zircon age data to demonstrate the recycling of the Rakaia Terrane into Rakaia strata itself and into Pahau Terrane strata. Sandstone clast major and trace element chemical data largely support petrographic observations derived from thin-section analysis. The similarities of petrographic and geochemical data between sandstone clasts from the Rakaia Terrane and Rakaia sandstones suggest that clasts in the Permian Te Moana and Late Triassic Lake Hill Conglomerates were derived by autocannibalistic reworking of older, consolidated, Rakaia sediments. Data from sandstone clasts from the Pahau Terrane suggest that uplift of the Rakaia Terrane continued into the Cretaceous. These Pahau Terrane clasts indicate that at the time of the Pahau sedimentation Permian to early Late Triassic Rakaia rocks were exposed and recycled into the Pahau Basin.

The Lower Cretaceous Way Group of northern Chile: An alluvial fan-fan delta complex

Science.gov (United States)

Flint, S.; Clemmey, H.; Turner, P.

1986-01-01

Alluvial fan sediments of the Lower Cretaceous Coloso Basin in northern Chile were deposited in a half-graben and derived from andesitic volcanics of a former island arc. Transport directions were towards the east, away from the present-day Peru-Chile trench. Grain flow, density modified grain flow and sheetflow processes were responsible for most of the sediment deposition with cohesive debris flows playing only a minor part. An early phase of conglomerate deposition (Coloso Formation) into a restricted basin records the transition from proximal fan facies with abundant grain flows and remobilized screes to mid-fan facies dominated by sheetflows. Stratiform copper mineralization near the top of the lower conglomerates is related to the unroofing of the Jurassic island arc. This mineralization comprises copper sulphide-cemented sands and gravels and formed by the reaction of mineralized detritus with diagenetic and hydrothermal solutions. A later phase of deposition (Lombriz Formation) includes sandstones, siltstones and conglomerates with a source area different from the Coloso Formation. This change in source may be related to strike-slip tectonics as the basin extended. The Lombriz conglomerates pass distally (eastwards) into red sandstones and purple siltstones with thin limestones deposited under marine conditions. This sequence is interpreted as a major fan delta complex. It passes conformably into marine carbonates of the Tableado Formation signifying the complete drowning of the basin in lower Cretaceous times.

Propagation of biochirality: crossovers and nonclassical crystallization kinetics of aspartic acid in water.

Science.gov (United States)

Lee, Tu; Lin, Yu Kun; Tsai, Ya Chung; Lee, Hung Lin

2013-11-01

All experimental procedures discussed could be treated as a screening tool for probing the existence of molecular association among the chiral molecules and the solvent system. The molecular association phases of a racemic conglomerate solution (CS) and a racemic compound solution (RCS), and the templating effect of aspartic acid solid surface were observed to minimize the chance of redissolving racemic conglomerate and racemic compound aspartic acid in water and reforming an RCS in crossovers experiments. Only 1 %wt% of l-aspartic acid was adequate enough to induce a transformation from a racemic compound aspartic acid to a racemic conglomerate aspartic acid. This would make the propagation of biochirality more feasible and sound. However, tetrapeptide, (l-aspartic acid)4 , failed to induce enantioseparation as templates purely by crystallization. Nonclassical crystallization theory was needed to take into account the existence of a CS. Fundamental parameters of the crystallization kinetics such as the induction time, interfacial energy, Gibbs energetic barrier, nucleation rate, and critical size of stable nuclei of: (i) racemic compound aspartic acid, (ii) racemic compound aspartic acid seeded with 1 %wt% l-aspartic acid, (iii) racemic conglomerate aspartic acid, and (iv) l-aspartic acid were evaluated and compared with different initial supersaturation ratios. Morphological studies of crystals grown from the crystallization kinetics were also carried out. © 2013 Wiley Periodicals, Inc.

The Blind River uranium deposits: the ores and their setting

International Nuclear Information System (INIS)

Robertson, J.A.

1976-01-01

The Matinenda Formation (basal Huronian) comprises northward-derived arkose, quartzite, and pyritic, uraniferous oligomictic conglomerate that contains 75 percent of Canada's uranium reserves. The conglomerate beds occur in southeasterly striking zones controlled by basement topography down-sedimentation from radioactive Archean granite. The mineralization is syngenetic, probably placer. Drab-coloured rocks, uranium and sulphide mineralization, and a post-Archean regolith formed under reducing conditions, suggest a reducing environment. Sedimentary features indicate deposition in fast-flowing shallow water, and possibly a cold climate. (author)

Yilemen basin is a typical Mesozoic intra-mountain one. The author analyses characteristics of depositional system and the prospect of sandstone-type uranium deposit in the sedimentary cover of the Bayanhua Formation, Lower Cretaceous. Authors suggest that the conglomerate, sandstone-conglomerate and sandstone beds of braided stream and delta are favourable horizons for locating phreatic and interlayer oxidation zone sandstone-type uranium deposits, i.e. the northwestern side of Dalai uplifted zone, the Chagantaigebuqi narrow sag, and the southern area of Baolinbuqi

La geografia come monumento. Il progetto di Auguste Perret per Le Havre / Geography as a monument. The Auguste Perret’s project for Le Havre

Directory of Open Access Journals (Sweden)

Antonio Nitti

Full Text Available Nel progetto di Auguste Perret per Le Havre una forma chiaramente compatta ed evocativa dell’urbanità della città storica si definisce a partire dalle relazioni stabilite con quegli elementi della geografia fisica che costituiscono l’identità del luogo nel quale questa si colloca, e costruisce una significativa relazione con gli spazi aperti e vasti della natura, acquisendo in questo modo quella ‘dimensione’ e quei caratteri propri della città contemporanea. Nei suoi spazi collettivi, che rimandano a una cultura dell’abitare che affonda le proprie radici nella più generale storia della città francese, Le Havre rappresenta sé stessa e traduce nella Place de l’Hôtel de Ville le ripide pendici della falesia, nella Porte Océane l’orizzonte lontano dell’Oceano, nel Front-de-mer Sud l’altra riva della foce della Senna, e fa di questi i veri ‘monumenti’ della città. / In the Auguste Perret’s project for Le Havre a clearly compact form, evocative of urbanity of the historical city, is defined starting from the relations established with those elements of physical geography which constitute the identity of the place where the city is located, and builds a significant relationship with the open and vast spaces of nature, thus acquiring the ‘size’ and those features of the contemporary city. In its public spaces, which refer to a culture of inhabiting that is rooted in the more general history of the French city, Le Havre represents itself and translates in the Place de l'Hôtel de Ville, the steep slopes of the cliff, in the Porte Oceane the distant horizon of the ocean, in the Front-de-mer South the other bank of the mouth of the Seine, and defines these as the real 'monuments' of the city.

Hydrophobizing coatings for cultural heritage. A detailed study of resin/stone surface interaction

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

The Caracol Disk of Chichén Itzá (929-932 CE. Some Throughts on Epigraphy and Iconography

Directory of Open Access Journals (Sweden)

Péter Bíró

2016-06-01

Full Text Available The sculpture referred to as the ‘Tenoned Disk’, which was recovered from the Caracol building at Chichén Itzá, is a monument decorated with a bass-relief carving displaying historical figures and accompanying hieroglyphic text that is located on the rim of the monument. This text makes reference to several persons named using a Maya Yucatec language. The date of 8 Ajaw is also recorded on the sculpture. For some unknown reason this monument has been overlooked by scholars who have sought to reconstruct the chronology of the site. Crucially, this monument records an important moment in the history of Chichén Itzá and of Yucatán in general: the arrival of the “Mexican-Toltec” people, and the re-foundation of the city under a new social construct that included foreigners and local nobility.

Gainullin, I. I.; Khomyakov, P. V.; Usmanov, B. M.

2018-01-01

Archaeological monuments are an essential part of the cultural landscape. Modern condition of archaeological monuments of the Republic of Tatarstan is discussed in this article. Fortified settlements, with the system of defensive fortifications were selected as the objects of study, as they are easily identified by remote sensing data. Due to the fact, that most of monuments are located on the small rivers banks, the first task of our study was to assess the risk of their destruction by natural processes. The second objective was to evaluate the role of the human factor in archaeological sites destruction. One of the main used methods is archival and modern remote sensing data analysis that also made able to correct the form of study settlements in comparison with existing plans as well as their size and location in the landscape. The results of research will help to identify trends in monuments state and to quantify the risks of their destruction.

2017-10-01

This publication is devoted to the problem of preservation and restoration of the architectural monument as an element of the historical environment. The notion of “immovable monument of history and culture” is specified. Modern methods of restoration and repair-conservatory works are analyzed. The main principles of complex studies of monument buildings are considered taking into account their interactions with the environment. The necessity of assessing the physical state of structures and materials of the architectural monument for selecting the optimal technology for repair work, preserving the historical and cultural landscape is shown. A brief history of the construction and repair of the monastery at Jasna Gora in Czestochowa (Poland) is presented. The restoration of the Jasna Gora ensemble was a complex kind of construction work: repair, conservation, consolidation and renovation of architectural monuments. The ground and underground structures of the main buildings and structures have been restored and strengthened. The program of restoration work on the task “Complex restoration of the building of the monastery of the Paulin Fathers on Jasna Gora” (2004-2013) included three stages: 1. “Reconstruction and restoration of the buildings of the monastery of the Paulin Fathers on Jasna Gora” (2007-2010), 2. “Conservation and renovation of the building of the Basilica of the Holy Cross and the Nativity of the Virgin” (2007-2012), 3. “Renovation of the North curtain - the entrance to the territory of the monastery of the Paulin Fathers on Jasna Gora” (2013). Restoration was based on a thorough examination of the monument and aimed to maximally preserve the historical, constructive and artistic features of the monastery complex, ensure its long existence. In addition to preserving the historical, technical and artistic qualities of the ensemble of the monastery, the tasks of organizing the environmental monument were resolved. Completed

A note on coarse-grained gravity-flow deposits within proterozoic lacustrine sedimentary rocks, Transvaal sequence, South Africa

Science.gov (United States)

Eriksson, P. G.

A widely developed, thin, coarse-matrix conglomerate occurs within early Proterozoic lacustrine mudrocks in the Transvaal Sequence, South Africa. The poorly sorted tabular chert clasts, alternation of a planar clast fabric with disorientated zones, plus normal and inverse grading in the former rock type suggest deposition by density-modified grain-flow and high density turbidity currents. The lower fan-delta slope palæenvironment inferred for the conglomerate is consistent with the lacustrine interpretation for the enclosing mudrock facies. This intracratonic setting contrasts with the marine environment generally associated with density-modified grain-flow deposits.

Archaeological monuments are an essential part of the cultural landscape. According to UNESCO directive, the "cultural landscape" is understood not simply as a result of joint creativity of man and nature, but as a purposefully formed natural and cultural territorial complex, which has structural, functional integrity, developing in specific physical and geographical, cultural and historical conditions. This article discusses the modern condition of the archaeological monuments of the Republic of Tatarstan, as a manmade part of the cultural landscape. Fortified settlements, with the system of defensive fortifications, were selected as the objects of study, as they are easily identified by remote sensing data. Identification and evaluation of monuments destruction risks is a priority in the study of medieval settlements. Due to the fact, that most of monuments is located on the small rivers banks, the first task of our study was to assess the risk of their destruction by natural processes. The second objective was to evaluate the role of the human factor in archaeological sites destruction. One of the main used methods is archival and modern remote sensing data analysis that also made able to correct the form of study settlements in comparison with existing plans, as well their size and location in the landscape. The results of research will help to identify trends in the monuments state and quantify the risks of their destruction.

1978-10-01

During July--August 1976, waters and sediments were collected from streams and lakes over an area of 100,000 km 2 around Kotzebue, Alaska, as part of the National Uranium Resource Evaluation Hydrogeochemical and Stream Sediment Reconnaissance. The work provides multielement results for 949 waters and 886 sediments from 979 locations. Of these, 492 waters and 452 sediments are from 517 locations in the proposed Chukchi Imuruk Reserve; 447 waters and 423 sediments are from 451 locations in the proposed Selawik Wildlife Refuge; and 10 waters and 11 sediments are from 11 locations in the proposed Cape Krusenstern Monument. The field data, with concentrations of 13 elements in the waters and 43 in the sediments, are presented, and the sample locations are shown on accompanying plates. The waters were analyzed for uranium by fluorometry or delayed-neutron counting and calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese, molybdenum, nickel, titanium, and zinc by plasma-source emission spectrography. The sediment samples were analyzed for uranium by delayed-neutron counting, beryllium and lithium by arc-source emission spectrography, bismuth, cadmium, copper, lead, nickel, niobium, silver, tin, and tungsten by x-ray fluorescence, and aluminum, antimony, barium, calcium, cerium, cesium, chlorine, chromium, cobalt, dysprosium, europium, gold, hafnium, iron, lanthanum, lutetium, magnesium, manganese, potassium, rubidium, samarium, scandium, sodium, strontium, tantalum, terbium, thorium, titanium, vanadium, ytterbium, and zinc by neutron activation.

Opdyke, Neil D; DiVenere, Victor J

2004-09-14

Three sections of Chesterian Mauch Chunk Formation in Pennsylvania have been studied paleomagnetically to determine a Late Mississippian magnetic polarity stratigraphy. The upper section at Lavelle includes a conglomerate with abundant red siltstone rip-up clasts that yielded a positive conglomerate test. All samples were subjected to progressive thermal demagnetization to temperatures as high as 700 degrees C. Two components of magnetization were isolated: a synfolding "B" component and the prefolding "C" component. The conglomerate test is positive, indicating that the C component was acquired very early in the history of the sediment. A coherent pattern of magnetic polarity reversals was identified. Five magnetozones were identified in the upper Lavelle section, which yields a pattern that is an excellent match with the pattern of reversals obtained from the upper Mauch Chunk at the original type section of the Mississippian/Pennsylvanian boundary at Pottsville, PA. The frequency of reversals in the upper Mississippian, as identified in the Mauch Chunk Formation, is approximately one to two per million years, which is an average for field reversal through time.

Nenering Formation is essentially made up of semi-consolidated sediments, which are divided into basal conglomerate beds, conglomeratic sandstone, cross-bedded sandstone, and siltstone to muddy layers facies. It is overlie unconformable to the Berapit Formation, but conformable to the Kroh and Grik Formations. The stratigraphy of Nenering Formation is a fining upwards sequence where the thickness of conglomerate beds become thinner upwards and become thicker for conglomeratic sandstone. The thickness varies from 0.5 m to tenths of meters. The more sandy in the upper portion (cross-bedded sandstone) overlie with thin siltstone and mud stone facies. The clast and grain composition suggested that the material making up the sedimentary sequence were derived predominantly from the erosion of granitoid rocks and sedimentary and metamorphic rocks constitute a minor provenance. Imbrications and the trend sizes of clasts indicate that the paleo-current flow toward northeast. Cross bedding that was found in conglomerate and sandstone indicates the main channel depositional environment. The sequence stratigraphy of this area match with the Saskatchewan fluvial braided channel model. (author)

The uranium deposits of Ontario

International Nuclear Information System (INIS)

Robertson, J.A.

1981-01-01

The principal types of uranium deposits in Ontario are carbonatites and fenites, alkalic volcanic rocks, pegiatites, calc-silicate rocks, pyritic quartz-pebble conglomerates, polymictic conglomerates and some pelitic rocks, and various 'pitchblende' deposits including late Precambrian unconformities, possibly late Precambrian diabase dikes, and other unconformities: carbonates, sandstones, lignites, and semi-pelitic rocks of middle and upper Precambrian age. Only red unzoned pegmatite and the pyritic quartz-pebble conglomerate have supported production. Ontario reasonably assured and estimated resources in the economic and subeconomic categories in 1977 amounted to 553 000 tonnes U, and 1977 production was 4000 tonnes U. Measured, indicated, and inferred resources in the Elliot Lake - Agnew Lake area are at least 400 000 tonnes U. The latter deposits are also a significant thorium resource. Geological features reflecting major changes in physics and chemistry are prime controls on distribution of uranium deposits. Geological province and subprovince boundaries, major faults, higher metamorphic grades, domain boundaries related to quartz monzonite batholiths, alkalic complexes, and the distribution of carbonate rocks are examples of such geological features

Highlights: • Geochemical study of black crusts developed on three monuments located in Milan, Florence and Rome. • Trace element composition of the black crusts is greatly influenced by anthropogenic pollution. • Geochemical characterization of black crusts can be used as a reliable indicator of environmental pollution. - Abstract: This work presents results from a petrographic, morphological and chemical study of the black crusts developing on monuments in three Italian cities, the Cathedral of Milan, the Cathedral of St. Maria del Fiore in Florence, and the Vittoriano Monument in Rome. Black crusts (BCs) were studied with traditional techniques such as optical microscopy (OM), scanning electron microscopy coupled with energy-dispersive X-ray spectrometry (SEM-EDS) and infrared spectroscopic techniques (FT-IR), in combination with laser ablation inductively coupled mass spectrometry (LA-ICP-MS), which has shown itself to be particularly useful in determining concentrations of heavy metals in BCs. Although the BCs of the three monuments show general enrichment in heavy metals with respect to the substrate (S), interesting differences were observed among them. The BCs from Milan are the richest in heavy metals, particularly Pb and Zn, reflecting the severe air pollution of this very large city, which, in addition to its intense traffic, is located in the most highly industrialized area of Northern Italy. The BCs from the south-eastern side of the Cathedral of St. Maria del Fiore in Florence, facing a pedestrian area, show little enrichment in heavy metals, and those from the Vittoriano Monument in Rome, which is exposed to intense road traffic, display variable enrichment, attributable to mobile emission sources. Results show that the various enrichment trends in heavy metals observed in the BCs of these three monuments are due to many factors: various sources of anthropogenic pollution, sampling height, exposure, orientation, and the shape of the deposition

Monuments to Academic Carelessness

Science.gov (United States)

2014-01-01

In 1942, Katherine Frost Bruner published an article titled “Of psychological writing: Being some valedictory remarks on style.” It was published in Journal of Abnormal and Social Psychology, the journal for which she served as editorial assistant between 1937 and 1941. Her collection of advice to writing scholars has been widely quoted, including by several editions of The Publication Manual of the American Psychological Association. The most frequently quoted message in Bruner’s article deals with the importance of making sure that references in academic texts are complete and accurate. Exploring the citation history of this particular message reveals an ironic point: the great majority of those who have quoted Bruner’s words on reference accuracy have not done so accurately. The case may serve as a reminder of the importance of the basic academic principle of striving to use primary sources. The most startling finding in this study is how frequently this principle is violated, even by authors who advise and educate academic writers. PMID:28479644

Characterization of Near-Surface Geology and Possible Voids Using Resistivity and Electromagnetic Methods at the Gran Quivira Unit of Salinas Pueblo Missions National Monument, Central New Mexico, June 2005

Ball, Lyndsay B.; Lucius, Jeffrey E.; Land, Lewis A.; Teeple, Andrew

At the Gran Quivira Unit of Salinas Pueblo Missions National Monument in central New Mexico, a partially excavated pueblo known as Mound 7 has recently become architecturally unstable. Historical National Park Service records indicate both natural caves and artificial tunnels may be present in the area. Knowledge of the local near-surface geology and possible locations of voids would aid in preservation of the ruins. Time-domain and frequency-domain electromagnetic as well as direct-current resistivity methods were used to characterize the electrical structure of the near-surface geology and to identify discrete electrical features that may be associated with voids. Time-domain electromagnetic soundings indicate three major electrical layers; however, correlation of these layers to geologic units was difficult because of the variability of lithologic data from existing test holes. Although resistivity forward modeling was unable to conclusively determine the presence or absence of voids in most cases, the high-resistivity values (greater than 5,000 ohm-meters) in the direct-current resistivity data indicate that voids may exist in the upper 50 meters. Underneath Mound 7, there is a possibility of large voids below a depth of 20 meters, but there is no indication of substantial voids in the upper 20 meters. Gridded lines and profiled inversions of frequency-domain electromagnetic data showed excellent correlation to resistivity features in the upper 5 meters of the direct-current resistivity data. This technique showed potential as a reconnaissance tool for detecting voids in the very near surface.

Is the Pyramid of the Sun at Teotihuacan a mausoleum, or just a ceremonial monument? A similar question inspired Luis Alvarez over 30 years ago to carry out his famous muon detection experiment at the Chephren Pyramid, in Giza. A fortunate similarity between this monument and the Pyramid of the Sun is a tunnel, running 8 m below the base and ending close to the symmetry axis, which allows us to emulate Alvarez in a search for possible hidden chambers in one of the largest pyramids in Latin America. Here we elaborate on what is known about this monument, on a description of the proposed detector design, and its expected performance based on simulations. (Author)

Neogene palaeochannel deposits in Sudan - Remnants of a trans-Saharan river system?

The start of Nile-type trans-Saharan drainage systems in NE Africa during the Cenozoic is disputed. Stratigraphical and sedimentological data in Egypt are partly in conflict with the uplift history of potential source areas of water and sediment in East Africa. Here, we investigate outcrops of the Wadi Awatib Conglomerate in Sudan that provide the first evidence of northerly flowing Neogene rivers in the region. Dimension and relief of basal erosion surfaces, overall geometry of deposits and palaeocurrent indicators demonstrate that the deposits represent the fill of northward-oriented incised valleys. The conglomerates were deposited in deep gravel-bed rivers, by hyperconcentrated flows, tractions carpets and gravel bars, primarily during heavily sediment-laden floods of probably monsoonal origin. Stratigraphical and geomorphological relationships show that the deposits are between Eocene and Pliocene in age. Considering the structural history of the region and periods in the Cenozoic with palaeoclimatic conditions suitable for the production and transport of gravels, we hypothesize that the dramatic base-level fall during the Late Miocene Messinian salinity crisis in combination with a favorable palaeoclimate caused the incision of valleys and their subsequent filling with conglomerates. Sea-level change in the Mediterranean Sea and headward erosion of streams that were connected to the Egyptian Nile might have been the primary cause of valley incision and deposition of conglomerates, despite a location far inland from the coastline. We suggest that the deposits document a relatively young Neogene (Messinian to early Pliocene) trans-Saharan river system unrelated to uplift of the Ethiopian Plateau.

To establish regional prevalences of anemia in pregnant women receiving care at public clinics in Peru in 2015 and identify high-prevalence district conglomerates. An ecological study was carried out on data from pregnant women with anemia registered on the Nutritional Status Information System (SIEN) who received care in 7703 public clinics in 2015. Regional and district prevalences of gestational anemia were calculated. District conglomerates with a high prevalence of gestational anemia were identified using the Moran Index. Information was gathered from 311,521 pregnant women distributed in 1638 districts in Peru. The national prevalence of anemia was 24.2% (95% confidence interval [95% CI]: 24.0-24.3%), the rural prevalence was 30.5%, and the urban prevalence was 22.0%. The regions of Huancavelica (45.5%; 95% CI: 44.2-46.7%), Puno (42.8%; 95% CI: 41.9-43.7%), Pasco (38.5%; 95% CI: 36.9-40.0%), Cusco (36.0%; 95% CI: 35.3-36.8%), and Apurímac (32.0%; 95% CI: 30.8-33.1%) had the highest prevalences of anemia. The local Moran Index identified 202 high-priority districts (hot spots) (12.3% of total; 44 urban and 158 rural) located in Ancash, Apurímac, Arequipa, Ayacucho, Cajamarca, Cusco, Huancavelica, Huánuco, Junín, La Libertad, Lima, Pasco, and Puno containing high-prevalence district conglomerates. Gestational anemia in Peru has its highest prevalence rates in rural and southern mountainous areas. The district conglomerates with high prevalence rates of gestational anemia coincide with the areas of high regional prevalence.

Financialization impedes climate change mitigation: Evidence from the early American solar industry

Science.gov (United States)

Jerneck, Max

2017-01-01

The article investigates how financialization impedes climate change mitigation by examining its effects on the early history of one low-carbon industry, solar photovoltaics in the United States. The industry grew rapidly in the 1970s, as large financial conglomerates acquired independent firms. While providing needed financial support, conglomerates changed the focus from existing markets in consumer applications toward a future utility market that never materialized. Concentration of the industry also left it vulnerable to the corporate restructuring of the 1980s, when the conglomerates were dismantled and solar divisions were pared back or sold off to foreign firms. Both the move toward conglomeration, when corporations became managed as stock portfolios, and its subsequent reversal were the result of increased financial dominance over corporate governance. The American case is contrasted with the more successful case of Japan, where these changes to corporate governance did not occur. Insulated from shareholder pressure and financial turbulence, Japanese photovoltaics manufacturers continued to expand investment throughout the 1980s when their American rivals were cutting back. The study is informed by Joseph Schumpeter’s theory of creative destruction and Hyman Minsky’s theory of financialization, along with economic sociology. By highlighting the tenuous and conflicting relation between finance and production that shaped the early history of the photovoltaics industry, the article raises doubts about the prevailing approach to mitigate climate change through carbon pricing. Given the uncertainty of innovation and the ease of speculation, it will do little to spur low-carbon technology development without financial structures supporting patient capital. PMID:28435862

Palaeogene to Early Miocene sedimentary history of the Sierra Espuña (Malaguide complex, internal zone of the Betic cordilleras, SE Spain. Evidence for extra-Malaguide (Sardinian? provenance of oligocene conglomerates: Palaeogeographic implications

Directory of Open Access Journals (Sweden)

Geel, T.

1996-12-01

Full Text Available The Sierra Espuña is situated at the northern edge of the Internal Zone in the eastern Betic Cordilleras and is part of the unmetamorphosed Malaguide Complex. Palaeontological and sedimentological analysis of the Eocene to Aquitanian sediments on the northwest side of the Espuña yielded unexpected new information of importance for the reconstruction of the history of the Espuña itself and the Malaguides in general. The socalled Upper Eocene (Auversian rocks are of Early Oligocene (P20 age and contain supermature detritus derived from outside the Malaguide realm. The hundreds of meters thick limestone conglomerate formation of the Espuña is of Middle Oligocene (P21 age and represents a backstepping fan delta complex at the margin of a carbonate platform situated to the northeast of the Espuña. Analysis of the clasts suggests that this platform was a part of the north Sardinian block given the majority of fragments of Upper Jurassic sheltered inner platform (Clypeina-Trocholina limestones and dolomites. Contrary to former views (Paquet, 1966; Lonergan, 1993, the conglomerates cannot be considered to be the erosional products of Malaguide imbricated units. Therefore, one of the main arguments for early (Late Eocene to Oligocene thrusting and nappe emplacement in the Espuña area is not valido Other arguments for early kinematics are discussed, among others the allegedly continuous sedimentation from the Late Eocene until the Langhian northwest of the Espuña. Our data indicate the existence of a stratigraphic gap, comprising the middle Aquitanian to middle Burdigalian. A new model for the development of the Espuña within the Malaguide realm during the Palaeogene to Early Miocene is presented. Main thrusting and nappe emplacement is thought to have been taken place during the late Aquitanian. Finally, the recently proposed 2000 clockwise rotation of the Espuña as a coherent block during the Early to Middle Miocene (AlIerton el al., 1993 is

This report presents 27 measured sections from the Dockum Group of Late Triassic age, in the southern High Plains of eastern New Mexico and northwestern Texas. Many of the measured sections are only partial; the intent in those cases was to measure the parts of sections that had prominent sandstone/conglomerate beds or that had uranium deposits. No attempt was made to relate rock color to a rock color chart; rock colors are therefore approximate. Modal analyses (by thin-section examination) of sandstone and conglomerate samples and gamma-ray spectrometric analyses of the samples are presented in appendices

The effect of particle shape and size composition on the processes of powder vibratory compacting is considered. Using microstress measurements in compacted structures of conglomerated and disintegrated tungsten powders as well as powder strength testing the existence of a zone of transition from a structural deformation to a plastic one has been shown. The formation of phase interparticle contacts of practically stable strength (approximately 5-6 dyn) is a characteristic feature of the zone. The width of the transition zone greatly depends upon geometrical powder properties; 55-65 % for conglomerated tungsten, 63-66 % for integrated tungsten
