    Most people follow and are influenced by some kind of spiritual faith. We examined two ways in which religious faiths can in turn influence biodiversity conservation in protected areas. First, biodiversity conservation is influenced through the direct and often effective protection afforded to wild species in sacred natural sites and in seminatural habitats around religious buildings. Sacred natural sites are almost certainly the world's oldest form of habitat protection. Although some sacred natural sites exist inside official protected areas, many thousands more form a largely unrecognized "shadow" conservation network in many countries throughout the world, which can be more stringently protected than state-run reserves. Second, faiths have a profound impact on attitudes to protection of the natural world through their philosophy, teachings, investment choices, approaches to land they control, and religious-based management systems. We considered the interactions between faiths and protected areas with respect to all 11 mainstream faiths and to a number of local belief systems. The close links between faiths and habitat protection offer major conservation opportunities, but also pose challenges. Bringing a sacred natural site into a national protected-area system can increase protection for the site, but may compromise some of its spiritual values or even its conservation values. Most protected-area managers are not trained to manage natural sites for religious purposes, but many sacred natural sites are under threat from cultural changes and habitat degradation. Decisions about whether or not to make a sacred natural site an "official" protected area therefore need to be made on a case-by-case basis. Such sites can play an important role in conservation inside and outside official protected areas. More information about the conservation value of sacred lands is needed as is more informed experience in integrating these into wider conservation strategies. In

  2. Natural pigments and sacred art

    Since the dawn of mankind, cavemen has expressed himself through art. The earliest known cave paintings date to some 32,000 years ago and used 4 colours derived from the earth. These pigments were iron oxides and known as ochres, blacks and whites. All pigments known by the Egyptians, the Greeks, the Romans and Renaissance man were natural and it was not until the 18th century that synthetic pigments were made and widely used. Until that time all art, be it sacred or secular used only natural pigments, of which the preparation of many have been lost or rarely used because of their tedious preparation. As a geologist, a mineralogist and an artist specializing in iconography, I have been able to rediscover 89 natural pigments extracted from minerals. I use these pigments to paint my icons in the traditional Byzantine manner and also to restore old icons, bringing back their glamour and conserving them for years to come. The use of the natural pigments in its proper way also helps to preserve the traditional skills of the iconographer. In the ancient past, pigments were extremely precious. Many took an exceedingly long journey to reach the artists, and came from remote countries. Research into these pigments is the work of history, geography and anthropology. It is an interesting journey in itself to discover that the blue aquamarines came from Afghanistan, the reds from Spain, the greens Africa, and so on. In this contribution I will be describing the origins, preparation and use of some natural pigments, together with their history and provenance. Additionally, I will show how the natural pigments are used in the creation of an icon. Being a geologist iconographer, for me, is a sacrement that transforms that which is earthly, material and natural into a thing of beauty that is sacred. As bread and wine in the Eucharist, water during baptism and oil in Holy Union transmit sanctification to the beholder, natural pigments do the same when one considers an icon. The

  3. Effects of exotic Eucalyptus spp. plantations on soil properties in and around sacred natural sites in the northern Ethiopian Highlands

    Full Text Available Species of the genus Eucalyptus (common name eucalyptus are widely planted all across Ethiopia—including on large areas of land previously allocated to food production. In recent decades eucalyptus has also increasingly been planted on lands around and within “church forests,” sacred groves of old-aged Afromontane trees surrounding Ethiopian Orthodox Tewahido churches. These revered holy sites have long been recognized for their cultural values and also for their ecosystem services—including their potential to support species conservation and restoration, as church forests are some of the only remaining sanctuaries for many of Ethiopia’s indigenous and endemic plant and animal populations. Ethiopian Orthodox church communities have a long history of planting and nurturing indigenous tree seedlings to sustain church forest groves. However, due to the fast-growing nature of eucalyptuscombined with its widely recognized socio-economic benefits (as fuelwood, charcoal, construction wood, etc., this introduced species has been widely plantedaround church forests—in some cases even replacing native tree species within church forests themselves. In many developing country contexts the introduction of exotic eucalyptus has been shown to have ecological impacts ranging from soil nutrient depletion, to lowering water tables, to allelopathic effects. In this study, we collected soil samples from indigenous forest fragments (church forests, adjacent eucalyptus plantations, and surrounding agricultural land to examine how eucalyptus plantations in Ethiopian Orthodox church communitiesmight impact soil quality relative to alternative land uses. Soil properties, including organic matter, pH, total nitrogen, and total phosphorus were measured in samples across 20 church forest sites in South Gondar, East Gojjam, West Gojjam, Awi, and Bahir Dar Liyu zones in the Amhara Region of the northern Ethiopian Highlands. Findings indicate that although soil in

    Full Text Available Sacred sites are of conservation value because of their spiritual meaning, as cultural heritage and as remnants of near-natural biotopes in landscapes strongly transformed by man. The vegetation of sacred sites in Morocco was studied recently. Information about their number, spatial pattern or relief position is fragmentary. However, these parameters are important to evaluate their role as refuge for organisms and their representativeness of potential natural vegetation. Therefore, density and spatial pattern of sacred sites on the Tangier Peninsula in NW Morocco were studied based on records on topographic maps and by ground check. Their relief position was examined calculating a logistic regression model based on site-presences and random pseudo-absences. A ground check showed that around 67% of the existing sacred sites are documented in the topographic maps. They occur in the whole study area but are agglomerated around settlements. Although sacred sites occur with preference at elevated sites they can be found in almost all relief positions, thus offering the potential of supporting different types of climax vegetation (climatic climax and pedoclimax. Because of their abundance (around 29 sacred sites / 100 km² and their distribution pattern they could serve as elements of a biotope network in degraded landscapes.

  6. History of Tree Growth Declines Recorded in Old Trees at Two Sacred Sites in Northern China.

    2017-01-01

    Old forests are an important component in sacred sites, yet they are at risk of growth decline from ongoing global warming and increased human activities. Growth decline, characterized by chronic loss of tree vigor, is not a recent phenomenon. Knowledge of past occurrence of declines is useful for preparing conservation plans because it helps understand if present day forests are outside the natural range of variation in tree health. We report a dendroecological study of growth decline events in the past two centuries at two sacred sites, Hengshan and Wutaishan, in Shanxi province of northern China. Tree rings collected at both sites show distinct periods of declining growth evident as narrow rings. These occurred in the 1830s in both sites, in the 1920s in Wutaishan and in the 2000s in Hengshan. By comparing the pattern of grow declines at the two sites, we hypothesize that resistance of tree growth to external disturbances is forest size dependent, and increased human activity might be a factor additional to climatic droughts in causing the recent strong growth decline at Hengshan Park. Despite these past declines, the forests at both sites have high resilience to disturbances as evidenced by the ability of trees to recover their growth rates to levels comparable to the pre-decline period. Managers should consider reducing fragmentation and restoring natural habitat of old forests, especially in areas on dry sites.

    Full Text Available This paper explores how residents of México City appropriate public spaces by transforming local places into sacred sites.  This sacred quality is achieved by installing crucifixes, altars and niches for virgins and saints.  These symbols of folk religion not only adorn public sites, but also offer protection, serve as mnemonic devices and manage spatial liminality -all this in a chaotic city where public spaces are considered to be almost extinct.  These elements -- faces, proper names, common religious symbols- mark “anonymous” urban spaces, generating meaning and memory for inhabitants.  In this fashion, public spaces become a scenario for projecting personal elements of  neighborhood groups.

    2018-01-01

    A space can be sacred, providing those who inhabit a particular space with sense of transcendence-being connected to something greater than oneself. The sacredness may be inherent in the space, as for a religious institution or a serene place outdoors. Alternatively, a space may be made sacred by the people within it and events that occur there. As medical providers, we have the opportunity to create sacred space in our examination rooms and with our patient interactions. This sacred space can be healing to our patients and can bring us providers opportunities for increased connection, joy, and gratitude in our daily work.

  14. Sustainability and sacred values

    Directory of Open Access Journals (Sweden)

    John Cairns Jr.

    2002-09-01

    Full Text Available Successful implementation of the quest for sustainable use of the planet requires that human society both reexamine and expand present views of what is sacred and what is not. The most important aspect will be going beyond a homocentric focus to a biocentric emphasis. A unifying theme would be the desire to leave a habitable planet for human descendants and those of other species. It is unlikely that society can be confident of achieving sustainability until persuasive evidence supporting this belief has existed for several generations. In order for sustainable use of the planet to persist indefinitely, the conditions essential to this state must be morally preserved on sacred grounds. Viewing natural systems as sacred requires not only preventing damage to them but, wherever possible, repairing damage to them caused by humankind.

Today, the Tarim is home to China’s Uyghurs, a Turkic-speaking Muslim community whose ancestral ties to the region date back to at least the ninth century CE. For them, the Taklamakan is sacred land, enveloping the political and religious heroes of a storied past who are buried in countless mausoleums (in Uyghur: mazâr that dot the desert landscape.

    Late in February, deep in the heart of the northern hemisphere winter, Ojibwe people know to look to the east a few hours after sunset and offer tobacco to Mizhi Bizhiw -Curly Tail, the Great Spirit Cat in the night sky. There are many beautiful and layered teachings about Mizhi Bizhiw - Curly Tail relating to the coming of spring, respect for the water, sugar bush camp, but most important; knowing the stars meant survival.Painted high on the granite rock cliffs above the glacial waters in red ochre is the Mizhi Bizhiw - Curly Tail constellation. Along with the Ojibwe lion are two neighboring seasonal constellations: Mooz (Pegasus) and Biboonkionini -Wintermaker (Orion+). On Lake Hegman in the Boundary Waters Canoe Area located near Ely, Minnesota, a sacred reflection, an earth-sky mirroring is illustrated. It is here that tangible and intangible star knowledge meet.In D(L)akota star knowledge one of the most important teachings is kapemni. Wrapped up in this one word are layers of meaning that can be thought of as ‘As it is above; it is below.’ Imagine two tipis stacked vertically. The top triangle is inverted so that the pair meets at the apex. It is understood that the top realm represents the sky above, the stars or the spirit world. The bottom tipi represents the Earth, the material or the physical world.On Summer Solstice each year the Sun can be found in the Mato Tipila - Bear’s Lodge D(L)akota constellation (Gemini). The day when this astronomical alignment happens is known as the ‘Wacipi - Sundance Ceremony in the Stars’. At this time traditionally D(L)akota people would meet at Mato Tipila Paha - Grey Horn Butte (Devil’s Tower) in northeast Wyoming and participate in the earthly Wacipi - Sun Dance ceremony. This is a beautiful example of a kapemni pair or an earth-sky mirroring.Presented here are just two examples of sacred star sites found in our region: Minnesota, North & South Dakota, US. These are examples of cultural heritage that is

    Our goal was to document effects of year-round supplemental feeding on breeding ecology of the Buff-throated Partridge, Tetraophasis szechenyii, within a Tibetan sacred site. We evaluated effects of supplemental feeding used as religious/cultural practices which could potentially aid conservation of endangered phasianids. We compared fed breeding groups to neighboring nonfed groups. Fed groups initiated first clutches significantly earlier than nonfed groups. Earlier laying groups within fed and nonfed groups showed significantly lower hatching rates than later groups; however, fed groups showed significantly higher hatching rates than nonfed groups laying in the same period. Earlier laying increased opportunities to renest. All six fed groups with clutch failures renested compared to only one of five nonfed groups with clutch failures. Fed female breeders showed significantly greater investment in their young with larger clutches and larger eggs, which likely increased survivability of early hatchlings. We observed no predation on birds at feeding sites and recorded only four cases of predation on incubating females, which showed no detectable difference between fed and nonfed groups. Ground-nesting birds typically face high risks of predation. Ten of the 48 groups nested in trees, which occurs in few phasianid species. Tree nests showed significantly higher hatching rates compared to ground nests; however, we found no significant difference in tree nesting between fed and nonfed groups. This partridge is one of four gallinaceous species with cooperative breeding. Breeding groups with helpers had significantly greater reproductive success than single pairs, and fed female breeders with helpers laid bigger eggs than single pairs. Comparing annual reproductive output per group, fed groups not only produced significantly more independent young (≥ 150 days post-hatching), their young hatched significantly earlier, which likely have greater reproductive value over

  10. Common Sense Approach to the Restoration of Sacred Art

    Directory of Open Access Journals (Sweden)

    Alphonso Lopez Pinto

    2014-12-01

    Full Text Available In this paper, Sacred Art is examined as an imitation of historia. Historia interprets historical human events as empirical, material and real while seeking to understand their moral and spiritual significance. It is from historia that sacred art can be understood, where Christ and the saints are portrayed in the integrity of their human natures united to symbols representing Divinity or grace in order to present a visual/contemplative narrative. Mortimer Adler rightly sees that the vision of the beautiful is inherently contemplative, thus sacred iconography provides a language that can form the common sense of men and women.

    Although primates are hunted on a global scale, some species are protected against harassment and killing by taboos or religious doctrines. Sites where the killing of sacred monkeys or the destruction of sacred groves is forbidden may be integral to the conservation of certain species. In 2004, as part of a distribution survey of Sclater's guenon (Cercopithecus sclateri) in southern Nigeria, we investigated reports of sacred monkeys in the Igbo-speaking region of Nigeria. We confirmed nine new sites where primates are protected as sacred: four with tantalus monkeys (Chlorocebus tantalus) and five with mona monkeys (Cercopithecus mona). During 2004-2006, we visited two communities (Akpugoeze and Lagwa) previously known to harbor sacred populations of Ce. sclateri to estimate population abundance and trends. We directly counted all groups and compared our estimates with previous counts when available. We also estimated the size of sacred groves and compared these with grove sizes reported in the literature. The mean size of the sacred groves in Akpugoeze (2.06 ha, n = 10) was similar to others in Africa south of the Sahel, but larger than the average grove in Lagwa (0.49 ha, n = 15). We estimated a total population of 124 Sclater's monkeys in 15 groups in Lagwa and 193 monkeys in 20 groups in Akpugoeze. The Akpugoeze population was relatively stable over two decades, although the proportion of infants declined, and the number of groups increased. As Sclater's monkey does not occur in any official protected areas, sacred populations are important to the species' long-term conservation. Despite the monkeys' destruction of human crops, most local people still adhere to the custom of not killing monkeys. These sites represent ideal locations in which to study the ecology of Sclater's monkey and human-wildlife interactions. (c) 2009 Wiley-Liss, Inc.

    Full Text Available Pleasure is an important motivation for fans to adopt texts. Fannish tattoos function to demonstrate affective investments in a text; they are also a performance of fandom and an example of sacred fan identity. Like engaging in cosplay or wearing clothing that features logos, fannish tattoos mark people as fans of a text. Furthermore, the more obscure the logo or fannish reference, the more performative the tattoo. Fannish tattoos help to construct a sacred fan identity. The sacred experience (as theorized by Émile Durkheim and his concept of the totem is imbued with meaning through choices that set it aside from the mundane. Within the context of fannish tattoos, fan affect gains similar significance.

    Natural remediation is a general term that includes any technology or strategy that takes advantage of natural processes to remediate a contaminated media to a condition that is protective of human health and the environment. Natural remediation techniques are often passive and minimally disruptive to the environment. They are generally implemented in conjunction with traditional remedial solutions for source control (i.e., capping, stabilization, removal, soil vapor extraction, etc.). Natural remediation techniques being employed at Savannah River Site (SRS) include enhanced bio-remediation, monitored natural attenuation, and phytoremediation. Enhanced bio-remediation involves making nutrients available and conditions favorable for microbial growth. With proper precautions and feeding, the naturally existing microbes flourish and consume the contaminants. Case studies of enhanced bio-remediation include surface soils contaminated with PCBs and pesticides, and Volatile Organic Compound (VOC) contamination in both the vadose zone and groundwater. Monitored natural attenuation (MNA) has been selected as the preferred alternative for groundwater clean up at several SRS waste units. Successful implementation of MNA has been based on demonstration that sources have been controlled, groundwater modeling that indicates that plumes will not expand or reach surface water discharge points at levels that exceed regulatory limits, and continued monitoring. Phytoremediation is being successfully utilized at several SRS waste units. Phytoremediation involves using plants and vegetation to uptake, break down, or manage contaminants in groundwater or soils. Case studies at SRS include managing groundwater plumes of tritium and VOCs with pine trees that are native to the area. Significant decreases in tritium discharge to a site stream have been realized in one phytoremediation project. Studies of other vegetation types, methods of application, and other target contaminants are

    Sacred values, such as those associated with religious or ethnic identity, underlie many important individual and group decisions in life, and individuals typically resist attempts to trade off their sacred values in exchange for material benefits. Deontological theory suggests that sacred values are processed based on rights and wrongs irrespective of outcomes, while utilitarian theory suggests that they are processed based on costs and benefits of potential outcomes, but which mode of processing an individual naturally uses is unknown. The study of decisions over sacred values is difficult because outcomes cannot typically be realized in a laboratory, and hence little is known about the neural representation and processing of sacred values. We used an experimental paradigm that used integrity as a proxy for sacredness and which paid real money to induce individuals to sell their personal values. Using functional magnetic resonance imaging (fMRI), we found that values that people refused to sell (sacred values) were associated with increased activity in the left temporoparietal junction and ventrolateral prefrontal cortex, regions previously associated with semantic rule retrieval. This suggests that sacred values affect behaviour through the retrieval and processing of deontic rules and not through a utilitarian evaluation of costs and benefits.

  3. The sacred geography of Kapila: the Kapilasrama of Sidhpur

    2003-01-01

    Full Text Available To most scholars of Hinduism, the sage Kapila is a person associated only with ancient India and known mainly as the mythical founder of the Sāmkhya system of religious thought. This is the Kapila whose teaching is known through Yuktidīpikā, the Sāmkhyakārikā by Isvarakrsna and other Sāmkhya texts and the tradition of technical commentaries on them. In India this Kapila belongs to a scholarly tradition preserved mainly by pandits with a knowledge of Sanskrit and, for the last hundred years, also by professors in the Indian university system. In this article, the symbolic significance of one of the most important pilgrimage centres connected with Kapila, Sidhpur in Gujarat, is explored. The close connection between the sacred narratives and the rituals performed at the pilgrimage centre is a significant feature of the sacred places devoted to Kapila. At every place of pilgrimage to Kapila there are narratives about him which account for the sacredness of the place. These narratives belong to the geography of Hindu India as much as to the mythology of the Hindu tradition. The life history of Kapila is engraved in a sacred landscape. The place where Kapila was born, the place where he gave the sacred knowledge of ultimate reality to his mother, the different places where he performed tapas, the place where he killed the sons of King Sagara are all part of India's imagined landscape. The promise of the Kapila pilgrimage sites is that these places have power in themselves to remove moral impurity and grant moksa to the pilgrims. The sacred narratives of Kapila function to make this promise trustworthy.

    Full Text Available Sacred or protected values have important influences on decision making, particularly in the context of intergroup disputes. Thus far, we know little about the process of a value becoming sacred or why one person may be more likely than another to hold a sacred value. We present evidence that participation in religious ritual and perceived threat to the group lead people to be more likely to consider preferences as protected or sacred values. Specifically, three studies carried out with Americans and Palestinians show: (a that the more people participate in religious ritual the more likely they are to report a preference to be a sacred value (Studies 1--3; (b that people claim more sacred values when they are reminded of religious ritual (Study 2; and (c that the effect of religious ritual on the likelihood of holding a sacred value is amplified by the perception of high threat to the in-group (Study 3. We discuss implications of these findings for understanding intergroup conflicts, and suggest avenues for future research into the emergence and spread of sacred values.

    Probabilistic seismic hazard studies completed for the Washington Public Power Supply System's Nuclear Plant 2 and for the US Department of Energy's N Reactor sites, both on the Hanford Site, suggested that the Lawrence Livermore National Laboratory seismic exposure estimates were lower than appropriate, especially for sites near potential seismic sources. A probabilistic seismic hazard assessment was completed for those areas that contain process and/or waste management facilities. the lower bound magnitude of 5.0 is used in the hazard analysis and the characteristics of small-magnitude earthquakes relatively common to the Hanford Site are addressed. The recommended ground motion for high-hazard facilities is somewhat higher than the Lawrence Livermore National Laboratory model and the ground motion from small-magnitude earthquakes is addressed separately from the moderate- to large-magnitude earthquake ground motion. The severe wind and tornado hazards determined for the Hanford Siste are in agreement with work completed independently using 43 years of site data. The low-probability, high-hazard, design-basis flood at the Hanford Site is dominated by dam failure on the Columbia River. Further evaluation of the mechanisms and probabilities of such flooding is in progress. The Hanford Site is downwind from several active Cascade volcanoes. Geologic and historical data are used to estimate the ashfall hazard

  8. A Preliminary Assessment of Ethiopian Sacred Grove Status at the Landscape and Ecosystem Scales.

    2013-04-01

    Full Text Available The northern Ethiopian landscape is dotted with small patches of church forests that are religious centers for the Ethiopian Orthodox Tewahido Church (EOTC. These sacred groves are what remain of the once vast tropical Afromontane dry forest. Herein we review the landscape pattern of sacred groves in the Amhara region of Ethiopia, and their local scale nutrient status at two sites, Zahara and Debresena. A total of 1,488 sacred groves were inventoried within the study area, yielding an overall density of one sacred grove for every twenty square kilometers. Sacred groves averaged a little over five hectares and were separated from one another by more than two kilometers. At the local scale we found that soil carbon and nitrogen stocks have decreased significantly between the forest interior and the clearing indicating decreased soil fertility. Together our data indicate that these sacred groves are vulnerable to loss because of their small average size, isolation from seed sources, and decreasing soil status.

  9. Religious and sacred imperatives in human conflict.

    Science.gov (United States)

    Atran, Scott; Ginges, Jeremy

    2012-05-18

    Religion, in promoting outlandish beliefs and costly rituals, increases ingroup trust but also may increase mistrust and conflict with outgroups. Moralizing gods emerged over the last few millennia, enabling large-scale cooperation, and sociopolitical conquest even without war. Whether for cooperation or conflict, sacred values, like devotion to God or a collective cause, signal group identity and operate as moral imperatives that inspire nonrational exertions independent of likely outcomes. In conflict situations, otherwise mundane sociopolitical preferences may become sacred values, acquiring immunity to material incentives. Sacred values sustain intractable conflicts that defy "business-like" negotiation, but also provide surprising opportunities for resolution.

    2017-07-01

    Sacred space and spirituality have long been used to heal the mind, body, and spirit. This article illuminates the origins of sacred space and its role as a healing environment from the first human construct, the burial mound, to the 5th Century BCE Greek healing city of Epidaurus. It then examines the role of spirituality as one of the necessary human institutions for a healthy society, according to the Italian philosopher Giambattista Vico. The conclusion then surveys three contemporary healing environments' architecture, the Department of Veteran Affairs Healing Environment Design Guideline (VAHEDG), and how these sacred spaces mend individual and community ailments.

    Screening of sites for the potential application and reliance upon monitored natural attenuation (MNA) can be done using MNAtoolbox, a web-based tool for estimating extent of biodegradation, chemical transformation, and dilution. MNAtoolbox uses site-specific input data, where available (default parameters are taken from the literature), to roughly quantify the nature and extent of attenuation at a particular site. Use of MNAtoolbox provides 3 important elements of site evaluation: (1) Identifies likely attenuation pathways, (2) Clearly identifies sites where MNA is inappropriate, and (3) Evaluates data requirements for subsequent reliance on MNA as a sole or partial corrective action.

  13. Sacred values and conflict over Iran's nuclear program

    Directory of Open Access Journals (Sweden)

    Morteza Dehghani

    2010-12-01

    Full Text Available Conflict over Iran's nuclear program, which involves a US-led policy to impose sanctions on Iran, is perceived by each side as a preeminent challenge to its own national security and global peace. Yet, there is little scientific study or understanding of how material incentives and disincentives, such as economic sanctions, psychologically affect the targeted population and potentially influence behaviour. Here we explore the Iranian nuclear program within a paradigm concerned with sacred values. We integrate experiments within a survey of 1997 Iranians. We find that a relatively small but politically significant portion of the Iranian population believes that acquiring nuclear energy has become a sacred value, in the sense that proposed economic incentives and disincentives result in a ``backfire effect'' in which offers of material rewards or punishment lead to increased anger and greater disapproval. This pattern was specific to nuclear energy and did not hold for acquiring nuclear weapons. The present study is the first demonstration of the backfire effect for material disincentives as well as incentives, and on an issue whose apparent sacred nature is recent rather than longstanding.

  14. 'Marriage is sacred': the religious right's arguments against 'gay marriage' in Australia.

    Science.gov (United States)

    Edwards, Jane

    2007-01-01

    In 2004, the Australian government legislated to prohibit 'gay marriage'; the religious right had lobbied vigorously for passage of this legislation. Drawing on Durkheim's theory of sacred and profane, this paper examines the argument proffered by right-wing Christians that allowing legalised unions between lesbians and between gay men would seriously undermine the institution of marriage and the family. Claims about the spectre of gays and lesbians marrying reveal a deeper unease about the status of heterosexual marriage and the nuclear family. These concerns, in turn, house a deeper unease about the nature and place of masculinity in contemporary Australian society. This disquiet about masculinity and masculine authority is isomorphic with concerns about challenges to the notion of an objective epistemological order. Marriage and nature are both sacred in Durkheimian terms because they must be radically separated from matters profane. By locating heterosexual marriage within the domain of nature, it is protected from contact with things that threaten its sacred status. However, Durkheim's theory of the sacred is simultaneously an account of the exercise of ideological power. Attempts to cast heterosexual marriage as sacred and, therefore, as inviolate are inextricably linked with attempts to protect an epistemological order linked to masculine authority.

    2017-01-01

    Acid mine drainage (AMD) is one of the main environmental issue caused by chemical and bacterial oxidation of pyrite (FeS 2 ) and other sulfite minerals when exposed to atmospheric conditions during mining. In Brazil, AMD occurs in a former uranium mine and contains radionuclides and other elements, which are precipitated from acidic water by liming. Due to the inefficiency of the treatment, contaminants overflow to the water reservoir of Indústrias Nucleares do Brasil – INB in Caldas. The multiplicity of interactions that can occur between the contaminants and the sediments of the reservoir requires a broader approach in order to understand the fixation and/or transport of these elements. In this work the natural remediation approach is reviewed and an initial chemical and radiochemical characterization of the reservoir sediments is presented. Uranium was determined by spectrophotometry, Ra-226, Ra-228 and Pb-210 by gamma spectrometry and zinc by ICP-OES. Twenty-six sediment samples were collected in the reservoir and a bathymetry survey by sonar was performed to determine the thickness of the sediment layer. All the data were processed using the ArcGIS program. To assess the potential mobility and bioavailability of contaminants and to study the role of bacterial sulfate reduction in the immobilization of these contaminants, Acid-volatile sulfide (AVS) analyzes will be performed as a further step.

  18. Natural Capital - putting a value on geological sites

    Science.gov (United States)

    Dunlop, Lesley

    2017-04-01

    Natural Capital is a mechanism through which a value can be placed on nature allowing it to be considered alongside other assets. When the Government of the United Kingdom produced a Natural Environment White Paper (The Natural Choice: securing the value of nature) in 2012 there was no direct mention of geosites, geoheritage or geodiversity. One ambition of the Natural Environment White Paper was to stop environmental degradation and to rebuild natural capital and to value it. Whilst landscapes are mentioned in the paper geodiversity is not directly and this has been problematic for funding and recognition within the UK. Natural Capital is being used as the basis for many of the environmental reviews therefore it is essential that geodiversity can be included within this. The Natural Capital Committee defines natural capital as 'those elements of the natural environment which provide valuable goods and services to people'. In the main, these goods and services are related to ecology/biodiversity rather than to the full range of natural capital. Specifically, the values associated with abiotic nature (geodiversity) are frequently undervalued or ignored. The English Geodiversity Forum have been producing case studies as to how this might be done for different locations and this paper will present the work of this and how a value can be attributed to geodiversity. For example links to tourism and recreation within areas such as the Jurassic Coast World Heritage Site and the Black Country proposed Geopark are easy to place a value on but it is more difficult with educational, scientific sites. Using an ecosystems services and biodiversity analogies this paper presents a framework that can be adopted for evaluation of geological sites.

    2016-07-01

    Full Text Available Traditional ecological knowledge is an integrated part of the African people and indeed the Rwandese for cultural purpose. Buhanga sacred forest is a relict forest of tremendous ecological importance to Rwandan society located in Musanze District. The aim of this study was to assess the traditional ecological knowledge and belief in the utilisation of some important plant species for the conservation of Buhanga sacred forest. Ecological information about ethnomedicinal and traditional practices were collected following structured questionnaire through interview involving eight traditional healers and three focus group discussions. Data were collected from the natural habitats, home gardens, farmlands and roadsides of Buhanga sacred forest. A total of 45 botanical taxa belonging to 28 families were reported to be used by the local community. Species such as Brillantaisia cicatricosa and Senna septemtrionalis were the popular species cited by traditional healers to treat human and animal diseases and ailments, respectively. The results of the study indicated that because of the cultural norms and values associated with the sacred forest, this has led to non-exploitation. The study presents key sites and plant species in which their use and belief can lead to their conservation. However, not only is it imperative to conserve traditional local knowledge for biocultural conservation motives but there is also need to train traditional healers on how to domesticate indigenous species as conservation measure because some species have become susceptible to extinction. Conservation implications: Highlighting indigenous species investigated in this research will provide a powerful tool for ensuring biodiversity conservation through community participation in a country of high population density in Africa. Some plant species that provided satisfactory Local Health Traditions among communities surrounding Buhanga can contribute as good material for further

    NONE

    2011-04-15

    Upon the proposal submitted by ist Standing committee 5 (Contaminated Sites Committee - ALA) the Federal / State Working Group on Soil protection employed an ad hoc subcommittee dealing with considering natural attenuation in remediating contaminated sites and preparing an inter-State position paper. In the present position paper the way how to consider natural attenuation in practical remediation of contaminated sites is described. The systematic approach outlined allows an understandable decision-finding. A way is shown how the competent soil protection authorities may exercise discretion and in the framework of checking the appropriateness of measures may decide on the implementation of MNA based on a MNA concept (MNA = monitored natural attenuation). It is, however, also explained that when carrying out MNA a decision always made in an individual case is concerned which should be made in a close agreement between the obligated party and the authority.

  2. Selection of radioactive waste disposal site considering natural processes

    International Nuclear Information System (INIS)

    Nakamura, H.

    1991-01-01

    To dispose the radioactive waste, it is necessary to consider the transfer of material in natural environment. The points of consideration are 1) Long residence time of water 2) Independence of biosphere from the compartment containing the disposal site in the natural hydrologic cycle 3) Dilution with the natural inactive isotope or the same group of elements. Isotope dilution for 129 I and 14 C can be expected by proper selection of the site. 241 Am and 239 Pu will be homogenized into soil or sediment with insoluble elements such as iron and aluminium. For 237 Np and 99 Tc anionic condition is important for the selection. From the point of view of hydrologic cycle, anoxic dead water zone avoiding beneath mountain area is preferable for the disposal site. (author)

  3. Estimating wind frequency limits for natural ventilation at remote sites

    International Nuclear Information System (INIS)

    Su, B.; Aynsley, R.

    2006-01-01

    Detailed wind data are collected at a limited number of sites, usually at airports. When a building is sited remote from the nearest wind data collection site, estimating wind frequency is more complex. The techniques involved come from the discipline of wind engineering. Where there is a relatively flat terrain between the wind data-recording site and the building site, simple computations can be made to account for the wind velocities over intervening terrain roughness. Where significant topographic features such as hills or mountains are present between the wind data-recording site and the building site, then boundary layer wind tunnel studies will be necessary to determine the influence of such features on wind speed and direction. Rough estimates can be calculated using factors used in some wind loading codes. When buildings are to be designed to take advantage of the energy efficiency offered by natural ventilation, it is important to estimate the actual potential for such ventilation. The natural ventilation potential can be estimated in terms of the percentage of time when wind exceeds some minimum value. For buildings near airports this is a relatively simple procedure. Such estimates are important as they also indicate the likely percentage of time when fans or other energy consuming devices will be needed to maintain indoor thermal comfort. This paper identifies the wind engineering techniques that can be used for such estimates and gives examples of such calculations

    1991-01-01

    Ground water and soil contamination at many of Michigan's oil and gas well sites has been attributed to natural gas dehydration processes. Since water was once thought to be the only by-product from the dehydration process, condensate from the process was discharged directly to the ground for several years. This condensate was later found to contain benzene, toluene, ethyl-benzene, and xylenes (BTEX), and the process of discharging condensate to the ground was stopped. Many oil and gas well sites had become impacted from the process during this time. Although condensate is no longer discharged to the ground, soil and water contamination still remains at many of these sites. In the last few years, the Michigan Department of Natural Resources has targeted over 90 well sites for assessment of contamination associated with gas dehydration. The results of many of these assessments indicate that soil and ground water have been impacted, and the State of Michigan has mandated cleanup of these sites. Remedial technologies which have been used to contain and/or clean up the sites include excavation and product removal, soil venting, purge and treat, and enhanced biodegradation. This paper is a discussion of the technology, implementation, and results from each of these methods

  6. Experiencing and Teaching Pilgrimage in a Sacred Spaces Course

    Directory of Open Access Journals (Sweden)

    Thomas J. Sienkewicz

    2018-03-01

    Full Text Available As part of an integrated studies curriculum at the author’s college, all juniors must take a Reflections course in which students consider personal values and analyze familiar and unfamiliar systems of thought and belief, in order to explore their own and others’ ideas about the ultimate meaning and purposes of life. “Sacred Places Past and Present”, is a course designed to fulfil this requirement. This course focuses on a number of important religious sites in the ancient Mediterranean and in the modern world, including the Parthenon, Olympia, Delphi, Stonehenge, and Muir Woods. These places are compared and contrasted in terms of what makes them sacred. Two pilgrimage experiences are part of this course: the hajj to Mecca and the Camino de Santiago de Compostela. In the past, the unit on the Camino focused on Emilio Estevez’s 2010 film “The Way”; however, during the summer of 2016, the author walked the Camino de Santiago. As a result, the course was substantially revised to reflect the author’s own personal experiences as a pilgrim. In particular, Paulo Coelho’s The Pilgrimage was incorporated into the course and students were given an opportunity to participate in a one-day pilgrimage walk in western Illinois.

    Little is known about the resting sites used by the giant panda (Ailuropoda melanoleuca), which restricts our understanding of their resting habits and limits conservation efforts. To enhance our understanding of resting site requirements and factors affecting the resting time of giant pandas, we investigated the characteristics of resting sites in the Wanglang Nature Reserve, Sichuan Province, China. The results indicated that the resting sites of giant pandas were characterised by a mean slope of 21°, mean nearest tree size of 53.75 cm, mean nearest shrub size of 2.82 cm, and mean nearest bamboo number of 56. We found that the resting sites were closer to bamboo than to trees and shrubs, suggesting that the resting site use of giant pandas is closely related to the presence of bamboo. Considering that giant pandas typically rest near a large-sized tree, protection of large trees in the forests is of considerable importance for the conservation of this species. Furthermore, slope was found to be an important factor affecting the resting time of giant pandas, as they tended to rest for a relatively longer time in sites with a smaller degree of slope.

    Full Text Available The article considers the concepts of violence and the sacred in the work of the French philosopher Georges Bataille. The author traces back the transformations of the concept of violence throughout the thinker’s carrier, namely in his early literary and philosophical experiences of the late 20s — early 30s, his reports for the College of Sociology (1937–1939 and his «systematic» postwar writings (1945–1962. The author also puts forward the hypothesis of the connection between the concept violence and the concept the sacred and demonstrates that it is most thoroughly represented in the last period of his work, although it may have been noted before. Diachronic consideration of the formation of these concepts allows the author to trace their correlation from the more or less random links mediated by artistic images and the other notions (sacrifi ce, for example to their explicit identification with each other and the systematic development in relation to such concepts as nature, life, being, intimacy, the animal state, expenditure, sacrifice, war and eroticism

In the novel, self-sacrifice does not function as a way of establishing a leadership position, but as a way to avoid the dangers associated with leadership, and possibly redeem humans......The leadership literature is full of stories of heroic self-sacrifice. Sacrificial leadership behaviour, some scholars conclude, is to be recommended. In this article we follow Keith Grint's conceptualization of leadership as necessarily pertaining to the sacred, but-drawing on Giorgio Agamben......'s notion of profanation-we highlight the need for organization scholars to profane the sacralizations embedded in leadership thinking. One example of this, which guides us throughout the article, is the novel A Wild Sheep Chase, by the Japanese author Haruki Murakami. By means of a thematic reading...

    HMIP has a research programme investigating some naturally radioactive sites as geochemical analogues of radionuclide migration. The objective is to test thermodynamic databases and computer codes used for modelling radionuclide migration under environmental conditions. This report describes the study of transport and retardation processes affecting natural radionuclides, mainly uranium (U), in the vicinity of pitchblende veins in the cliff at Needle's Eye on the Solway Coast, SW Scotland. The natural decay series results from this study have been used to develop a well constrained geochemical model within which the codes can be tested. A conceptual geochemical model for the behaviour of U at the site was developed in stage I of the study; work in stage II is concerned with improving the information available on the U source term, groundwater chemistry, U aqueous phase specification, U retardation by fracture-lining minerals during fissure flow of groundwater, U-organic associations and loss of U from the site by stream drainage.

  13. Psychoanalysis: the sacred and the profane.

    Science.gov (United States)

    Frosch, Allan

    2014-06-01

    Colleagues from a variety of perspectives have written about the propensity to enshrine psychoanalytic theory. The meaning of the word "enshrine" is to cherish as sacred an idea or philosophy and protect it from change. In other words, the way we view psychoanalysis, our theories of mind and technique, become holy writ and we have divided the world of theory into the sacred and the profane. This is the kiss of death for theory, which must constantly evolve and change, but comforting for the analyst who believes he is on the side of the right, the sacred. In this paper I will discuss how our propensity to enshrine theory has had a debilitating effect on the development of psychoanalysis and, in particular, as a treatment for the most vulnerable people who seek our help. I also address the idea that movement away from enshrined positions allows us to construct different versions of reality. In this context, the notion of "action at a distance" is presented along with the attendant idea of psychoanalytic entanglement.

  14. The dialogue between sacred, symbol and ritual to Mircea Eliade’s thinking

    Full Text Available Consequently implementing a vision that was mostly phenomenological and hermeneutical on the object and of the religious doctrine and content, Mircea Eliade had a remarkable contribution of originality and profoundness to the study of the problems related to sacred and profane and symbol and ritual. For the Romanian researcher, at the core of the dialectic game between sacred and profane, there is the behaviour of the religious man, opposed to the natural man, searching for divinity in an instinctive/ programmatic manner, trying to overcome his earthly condition by entering the inaccessible world of the sacred. Due to the more than obvious contemporaneity importance of the preoccupations and behaviour of homo religious, in post-modernity, starting from the dialogue between science and religion, we consider that there is the necessity and opportuness in a secularised and desacralized world to dedicate a study, 110 years later from the birth of the eminent professor, to the manner the Romanian eminent researcher Mircea Eliade saw and explained the sacred, the symbol and the ritual.

  15. The Ontological Concept of Sacred and Profane in Islam (analytic study

    Directory of Open Access Journals (Sweden)

    Abdulnaser Sultan Mohsen

    2014-06-01

    Full Text Available The term ‘sacred’ in the study of religions appeared at the beginning of the last century; Western scholars studied primitive religions in the world and combined it with the term of ‘profane’ in an ambivalent or a deterministic relationship. This study is questing the concepts of sacred and profane through Islamic prospective of ontology, in which it confirms that the dualism of sacred and profane is involved in the spirit existence, not in the natural or material as the Western thought alleges. It is through Muslim scholars’ study of spirit and existence, and linguistic study of sacred and profane that has clarified that the existence has sacredness as much as granted by spirit. Much is also the achievement of perfect existence, or retrieval of pure spirit and not retrieval of the origin of creation according to Christian thought. Otherwise, the existence became profane when it has been disintegrated by obstruction of spirit functions, or losing of the spirit totally. Therefore, the concept of sacred in Islam is the perfect existence by spirit; conversely, the profane is isintegration of spirit.

    Site Screening and Technical Guidance for Monitored Natural Attenuation at DOE Sites briefly outlines the biological and geochemical origins of natural attenuation, the tendency for natural processes in soils to mitigate contaminant transport and availability, and the means for relying on monitored natural attenuation (MNA) for remediation of contaminated soils and groundwaters. This report contains a step-by-step guide for (1) screening contaminated soils and groundwaters on the basis of their potential for remediation by natural attenuation and (2) implementing MNA consistent with EPA OSWER Directive 9200.4-17. The screening and implementation procedures are set up as a web-based tool (http://www.sandia.gov/eesector/gs/gc/na/mnahome.html) to assist US Department of Energy (DOE) site environmental managers and their staff and contractors to adhere to EPA guidelines for implementing MNA. This document is intended to support the Decision Maker's Framework Guide and Monitoring Guide both to be issued from DOE EM-40. Further technical advances may cause some of the approach outlined in this document to change over time.

  17. ASSESSING AEROBIC NATURAL ATTENUATION OF TRICHLOROETHENE AT FOUR DOE SITES

    Koelsch, Michael C.; Starr, Robert C.; Sorenson, Kent S. Jr.

    2005-01-01

    A 3-year Department of Energy Environmental Science Management Program (EMSP) project is currently investigating natural attenuation of trichloroethane (TCE) in aerobic groundwater. This presentation summarizes the results of a screening process to identify TCE plumes at DOE facilities that are suitable for assessing the rate of TCE cometabolism under aerobic conditions. In order to estimate aerobic degradation rates, plumes had to meet the following criteria: TCE must be present in aerobic groundwater, a conservative co-contaminant must be present and have approximately the same source as TCE, and the groundwater velocity must be known. A total of 127 TCE plumes were considered across 24 DOE sites. The four sites retained for the assessment were: (1) Brookhaven National Laboratory, OU III; (2) Paducah Gaseous Diffusion Plant, Northwest Plume; (3) Rocky Flats Environmental Technology Site, Industrialized Area--Southwest Plume and 903 Pad South Plume; and (4) Savannah River Site, A/M Area Plume. For each of these sites, a co-contaminant derived from the same source area as TCE was used as a nonbiodegrading tracer. The tracer determined the extent to which concentration decreases in the plume can be accounted for solely by abiotic processes such as dispersion and dilution. Any concentration decreases not accounted for by these processes must be explained by some other natural attenuation mechanism. Thus, ''half-lives'' presented herein are in addition to attenuation that occurs due to hydrologic mechanisms. This ''tracer-corrected method'' has previously been used at the DOE's Idaho National Engineering and Environmental Laboratory in conjunction with other techniques to document the occurrence of intrinsic aerobic cometabolism. Application of this method to other DOE sites is the first step to determining whether this might be a significant natural attenuation mechanism on a broader scale. Application of the tracer-corrected method to data from the Brookhaven

    The mechanisms underlying heavy metal accumulation, toxicity, and tolerance in higher plants are poorly understood. Since subcellular processes are undoubtedly involved in all these phenomena, it is of interest to study the extent, subcellular site and nature of intracellularly accumulated cadmium in higher plants. Whole plants supplied 109 CdCl 2 or 112 CdSO 4 accumulated Cd into roots and aerial tissues. Preparation of protoplasts from aerial tissues followed by subcellular fractionation of the protoplasts to obtain intact vacuoles, chloroplasts and cytosol revealed the presence of Cd in the cytosol but not in vacuoles or chloroplasts. No evidence was obtained for the production of volatile Cd complexes in tobacco

    A study of natural radioactivity in groundwater on and adjacent to the Savannah River Site (SRS) in Aiken (SC) was conducted to determine the spatial and temporal variations in the concentration of specific radionuclides. All available measurements for gross alpha particle activity, gross beta activity, uranium, Ra-226, Ra-228, and radon were collated. Relatively few radionuclide-specific results were found. Twenty samples from drinking water supplies in the area were collected in October 1987 and analyzed for U-238, U-234, Ra-226, Ra-228, and Rn-222. The aquifer type for each public water supply system was determined, and statistical analyses were conducted to detect differences among aquifer types and geographic areas defined at the country level. For samples from the public water wells and distribution systems on and adjacent to the site, most of the gross alpha particle activity could be attributed to Ra-226. Aquifer type was an important factor in determining the level of radioactivity in groundwater. The distribution and geochemical factors affecting the distribution of each radionuclide for the different aquifer types are discussed in detail. Statistical analyses were also run to test for aerial differences, among counties and the site. For all types of measurements, there were no differences in the distribution of radioactivity among the ten counties in the vicinity of the site or the site itself. The mean value for the plant was the lowest of all geographic areas for gross alpha particle activity and radon, intermediate for gross beta activity, and in the upper ranks for Ra-226 and Ra-228. It is concluded that the drinking water quality onsite is comparable with that in the vicinity. 19 refs., 5 figs., 5 tabs

Since subcellular processes are undoubtedly involved in all these phenomena, it is of interest to study the extent of, subcellular site of and nature of intracellularly accumulated cadmium in higher plants. Whole plants supplied 109 CdCl 2 or 112 CdSO 4 accumulated Cd into roots and aerial tissues. Preparation of protoplasts from aerial tissue followed by subcellular fractionation of the protoplasts to obtain intact vacuoles, chloroplasts and cytosol revealed the presence of Cd in the cytosol but not in vacuoles or chloroplasts. Particulate materials containing other cell components were also labeled. Of the 109 Cd supplied to plants, 2 to 10% was recovered in both cytosol preparations and in particulate materials. Cytosol contained proteinaceous--Cd complexes, free metal and low molecular weight Cd complexes. Labeling of protoplasts gave similar results. No evidence was obtained for the production of volatile Cd complexes in tobacco

    grouped into three categories: non-intervention, containment and removal. This report discusses in detail the necessary prerequisites, processes involved and applicability of non-intervention as a strategy for dealing with radioactive contamination. Particular emphasis is put on modelling tools as integral elements of monitored natural attenuation (MNA). It provides a comprehensive critique of, and explores the limits of, the applicability of MNA. While MNA is de facto relied upon in many instances where contamination cannot be completely removed from an engineered repository, it is emphasized that non-intervention is not equivalent to a 'do nothing' option. In order to rely on MNA safely, a thorough understanding of the site and the migration behaviour of the contaminants in the given environment is needed. This is gained from a comprehensive site investigation. This report complements other recent reports on remediation techniques and strategies with a less invasive concept. An extensive body of references including relevant web sites will help the reader to find more detailed or more up-to-date information.

  5. Contribution to Research of Mathematical Properties of Pre-Christian Slavic Sacred Landscape Structures

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Considerable amount of interpreted data indicates that the ancient Slavs positioned their sacred sites in a way which refers to characteristic Sun angles. The article addresses the question whether distances among such sites are based on a common unit of length. In particular, this article tackles that question applying the mathematical formalism on the following two assumptions: (i the absolute value of a distance between sacred sites was significant to the pre-Christian Slavic priests, along with the angles between lines connecting pairs of sites; (ii the distances were prevalently measured utilising the projections of isosceles right triangle on the horizontal plane, with the exceptions of flat grounds for which the distances were measured by walk. That assumption follows from the frequent occurrence of ratio 1:√2 in the analysed sacred sites. Based on the two stated assumptions the attempts are done to find the best possible length modules by using the probability distribution method of arithmetic sequences. The main property of length modules which are the least probable to appear by mere chance is that they account for as many as possible of distances from the analysed set of distances. The stated method is applied on numerous sacred systems described in literature. The result is that several common modules are extracted. The modules are subsequently correlated with the modules extracted in my recent article using the novel method which extracts the optimal common sub-module. Value of the length module thereby obtained is 30,9 m. It has 60 sub-units 0,515 m long (a cubit and 100 sub-units 0,309 m long (a foot. Multiples of 100 or 365 sub-units, respectively, are regularly encountered in the analysed set of sacred sites in the form of sub-harmonics of the observed distances. One may argue that results of the analysis of the distances contributed to the fact that the ancient Slavs were giving a lot of attention to a solar calendar and

    2013-10-01

    Full Text Available Tibetan thangkas (Buddhist scroll paintings are created as religious ritual objects. The fact that they are mainly considered as artworks in the Western world impacts on the decisions made for their display and conservation. This article explores the current approach to thangkas in Australian public collections and compares it with the views of contemporary Tibetan Buddhism practitioners. It underlines a few misconceptions at the source of conservation decision-making, and discusses practical outcomes of integrating the sacred dimension into professional practice against the backdrop of conservation’s Codes of Ethics. Conserving living religious heritage requires that professional ethical standards are adaptable to the needs of users. Existing frameworks for the conservation of sacred objects of pre-colonised, indigenous cultures provide useful models for the conservation of thangkas. This article argues that engaging with contemporary cultural groups to conserve religious significance is part of the mission of conservators. This is viewed as an expansion of conservation practice into the social realm, in a search for purposeful conservation that establishes the social relevance of our profession.

The Hindu temples of Lord Sri Laxminarasimha Swamy and Lord Hanuman, and the ethnic worship of mahua trees indicated it was a sacred grove which was selected as a Medicinal Plants Conservation Area. The exploration of Mallur Gutta resulted in the enumeration and documentation of plant wealth representing 470 species of 318 genera pertaining to 95 families of vascular plants. The importance of the grove as the residence for many rare or medicinal species in the state of Telangana is documented. The plant diversity is analyzed in terms of growth and life forms which indicate the prevailing microclimate, ecological opportunities and the species richness. The ecological services rendered by the Mallur Gutta forest ecosystem are documented to study how the great majority of the species are used by the ethnic and nonethnic people, and also the pilgrims who visit the shrine for its serenity. The study also identified two major threats to the conservation of hill ecosystem and the archeological site: 1 biotic pressure (the ever-increasing pilgrims, grazing by cattle, goat and sheep, the development activities taken up for the pilgrims, nondegradable litter thrown, collection of medicinal plants and widening of the pathway to the Chintamani perennial stream – the trampling and alien plant invasions of the marsh sustaining the stream; and 2 the potential for fire spreading from burning the litter. The study suggests the need to initiate remedial measures toward ecosystem

    Deep geological disposal is based on a multi-barrier concept in which clay materials often play an important role as geological barriers. Detailed investigations of suitable geological analogues may lead to a better understanding of the complex interrelations between transport and sorption of radionuclides in argillaceous media under natural conditions, and especially on very long-term scales relevant for Performance assessment (PA). The Ruprechtov site was chosen because its geological and geochemical conditions are similar to sedimentary sequences which cover often potential host rocks for underground waste repositories. It is situated in the north-western part of the Czech Republic in a Tertiary basin of the Eger (Ohre) rift composed of clay and organic material (coal, lignite), with places of high uranium conentrations. With a bilateral project this site has been investigated by GRS, Germany and NRI, Czech Republic in order to identify the main mobilisation/immobilisation processes for PA-relevant elements, namely uranium. The work presented here is a continuation of the previous project phase. In this last project phase the site investigation was limited to a small area of about 200 m 3 . Three exploration boreholes and two boreholes for detailed investigation were available at that time. The main intention of the new project phase was to enlarge the investigation area, in order to better understand the structure and the hydrogeochemical conditions of the overall system. On the one hand this includes the characterisation of the hydrogeological conditions in order to understand the regional groundwater flow and potential uranium transport processes on a larger spatial scale. Therefore the spatial extension of uranium-rich layers, water-bearing horizons and lithological units as well as groundwater ages and flow directions need to be determined. On that basis a conceptual model for the groundwater flow at Ruprechtov site can be developed. On the other hand it

  9. The Untidy Playground: An Irish Congolese Case Study in Sonic Encounters with the Sacred Stranger

    Directory of Open Access Journals (Sweden)

    Helen Phelan

    2017-11-01

    Full Text Available This paper explores the proposal that music, and particularly singing, has unique properties that render it amenable to encounters with “the other” or the sacred stranger. Drawing on the deconstructionist works of Kristeva and Derrida, as well as the postmodern hermeneutics of Kearney and Caputo, it explores current debate concerning the nature of “the sacred” in contemporary life and the erosion of the theistic/atheistic divide, while proposing a deepening of the debate through the inclusion of the performative. As philosophical and theological discourses embrace this aporia, it does so against the backdrop of unprecedented human migration. The concomitant cultural and social disruption throws up new questions around the nature and experience of religion, spirituality and the sacred. This paper explores these questions in the context of a Congolese choir called Elikya, which was established by a group of asylum seekers in Limerick city, Ireland, in 2001. In tracking the musical life of this choir over the last decade and a half, including two musical recordings and numerous liturgical, religious and secular performances, it suggests that the sonic world of the choir both performs and transcends these descriptors. Using a three-fold model of context, content and intent, the paper concludes that musical experiences such as those created by Elikya erode any easy divisions between the religious and the secular or the liturgical and the non-liturgical and provide sonic opportunities to encounter the sacred stranger in the untidy playground of creative chaos.

    Full Text Available On a global scale, the existing Sacred Groves (SGs are based on ancestral worship and focus on the conservation of forest patches. Sacred groves are distributed over a wide ecosystem and help in the conservation of rare and endemic species. Well preserved sites are store houses of biological, ecological, medicinal, ethno-cultural and religious values. We documented the state of 13 Sacred Groves in Balasore, Odisha during March 2011. For a detailed investigation, sample areas were set, for the assessment of floral and faunal diversity, ethno-cultural values and management status. A total of 58 floral species and 13 faunal species were recorded. In Balasore, Sacred Groves are small in size and can act as starting points for any long term conservation plan of biodiversity. The communities have kept their faith and traditions linked to these mini nuclei of rich biodiversity in the landscape. Therefore, any conservation program can begin from local communities, by taking them into consideration as trustworthy awareness building factors.

  17. From the numinous to the sacred.

    MacKenna, Christopher

    2009-04-01

    Jung took the idea of the 'numinous' from Rudolf Otto's book Das Heilige (E.T. The Idea of the Holy) and made it central to his understanding of religion. However, as Lucy Huskinson has recently pointed out, this involves a misreading of Otto's work in which we have to look beyond the numinous (which is the non-rational factor in religion) towards the 'holy' which, like a symbol, holds the rational and non-rational aspects of religious experience together in a personally transformative way. This understanding of the spiritual and psychological journey is supported by case material in which a numinous experience, arising in the context of intensive analytical psychotherapy, proved to be but the first step in a process which led, through a period of mourning, towards the development of the patient's capacity to symbolize. In the light of this, the author suggests that the sacred is to be found in the capacity for a certain quality of symbolic relatedness--to self and other--which may or may not be attended by numinous experience.

    Lawrence Livermore National Laboratory (LLNL) has developed seismic and wind hazard models for the Office of Nuclear Safety (ONS), Department of Energy (DOE). The work is part of a three-phase effort aimed at establishing uniform building design criteria for seismic and wind hazards at DOE sites throughout the United States. In Phase 1, LLNL gathered information on the sites and their critical facilities, including nuclear reactors, fuel-reprocessing plants, high-level waste storage and treatment facilities, and special nuclear material facilities. In Phase 2, development of seismic and wind hazard models, was initiated. These hazard models express the annual probability that the site will experience an earthquake or wind speed greater than some specified magnitude. In the final phase, it is anticipated that the DOE will use the hazard models to establish uniform criteria for the design and evaluation of critical facilities. 13 references, 2 figures, 1 table

  3. Desmond and Moore’s Darwin’s Sacred Cause

    Directory of Open Access Journals (Sweden)

    Allen Esterson

    2013-04-01

    Full Text Available In their book Darwin’s Sacred Cause (2009 Adrian Desmond and James Moore purport to demonstrate that they have provided an original explanation for the inspiration behind Darwin’s determined pursuit of an explanatory theory for the transformation of species of which he became convinced as a result of his experiences during the Beagle voyage of 1831 to 1836. This, they argue, was the “moral passion” that was evoked by his encountering the horrors of slavery during the periods he was able to disembark to explore areas of South America in the years 1832 to 1835. In short, they provide what they describe as “the untold story of how Darwin’s abhorrence of slavery led to our modern understanding of evolution.” This article explores the means by which the authors seek to persuade readers of the validity of their thesis, and concludes that far from providing compelling evidence, by providing a mass of historically interesting material relating to slavery that is actually tangential to their case, they obscure the fact that they fail to accomplish their aim. There is nothing in their account of events that provides a reason for preferring their explanation for Darwin’s devotion to understanding the processes involved in the transformation of species to the known historical facts of Darwin’s early zeal for natural science, exhibited in his childhood exploits with beetles and his more organized scientific activities when he was a student at Cambridge, enabled to come to fruition by his scientific activities during the voyage of the Beagle.

  13. AHP 21: Sacred Dairies, Dairymen, and Buffaloes of the Nilgiri Mountains in South India

    Directory of Open Access Journals (Sweden)

    Anthony R. Walker

    2012-12-01

    Full Text Available Approximately 1,500 Toda people inhabit the Nilgiri Mountains in south India. Arguably the most remarkable characteristic of Toda culture is the sacred nature of the husbandry of herds of long-horned mountain water buffaloes. No other community in India has so single-mindedly focused its ritual attention on one particular animal species. Every important task associated with the buffalo herds – milking, milk-processing, giving salt, naming, seasonal migrations, burning pastures, introducing new equipment into the dairies, etc. – has been embellished with ritual. Todas make a clear-cut distinction between temple and domestic buffaloes. Ordinary men (but not women herd the latter, whose milk and milk-products (buttermilk, butter, and clarified butter, but not flesh (since the community espouses vegetarianism may be consumed, bartered, or sold without restriction. Males who are responsible for herding temple buffaloes conduct their daily lives in a manner preserving greater ritual purity than ordinary men. Moreover, they are not just dairymen, but also the community's priests. They must guard the ritual purity of the dairies they serve, and all that is in them, for these are the Todas' temples – sacred places, infused with divinity.

    2009-01-01

    The Ruprechtov Natural Analogue (CZ) Programme has been focused on studying real system processes, relevant to performance assessment (PA) of sediment formations that can form the overburden of geological repository host rocks. The site has been extensively studied due to its geological constitution (granite - kaolin - clay - U mineralisation - organic matter). The presented study used Ruprechtov unique but well-described geological conditions in order to identify and characterise mobile organic matter (MOM) that can be easily released into groundwater and can influence PA relevant specie migration due to complexation/sorption reaction. The modem analytical method MALDI-TOF MS was used for characterisation. It was found that only a small fraction of sedimentary natural organic matter (NOM) from the site was easily releasable (max. 5%) as MOM, resulting in low organic substance concentration in natural groundwater. MOM amount released was decreasing with increasing NOM content. MALDI-TOF MS proved to be a useful tool to characterize organic substances, either natural ones or artificially released from natural organic matter samples. A noticeable fingerprint for all the MOM compounds analysed was found at MALDITOF MS spectra. This showed that MOM from the Ruprechtov site was in all cases composed of molecules with low molecular weight (under 1000 Da). As determined by the consequent geochemical analyses, despite groundwater reducing conditions MOM compounds would be mainly interacting with U(VI) in the groundwater, being present as more abundant U specie. Good correspondence of results enabled to consider the extracted humic acid HA 12/3 as a mobile organic matter fraction representative. (authors)

  19. Monasteries and tourism: interpreting sacred landscape through gastronomy

    Directory of Open Access Journals (Sweden)

    Silvia Aulet

    2017-01-01

    Full Text Available This article analyses the role of monasteries as a sacred space and how their relationship with tourism depicts a landscape of 'good taste'. Monasteries are examples of both tangible and intangible heritage, and are highly symbolic built spaces that have often become the guardians of tradition. They are strongly embedded within a local cultural landscape, which has determined their historical evolution. Monasteries used to be self-sufficient communities that relied on the resources available in their local environment, e.g. they produced their own wine, which was essential for the celebration of the Eucharist; or they preserved food from their own produce. Gastronomy in monasteries can be a tool to improve tourists' visitor experience, in so far as it respects the values that these sacred spaces represent. This article explores the literature on monasteries as sacred spaces; the relationship between their tangible and intangible heritage attributes; and how monasteries and their heritage are linked to tourism. This is illustrated through examples from Spain.

  20. Whole genome resequencing reveals natural target site preferences of transposable elements in Drosophila melanogaster.

    Directory of Open Access Journals (Sweden)

    Raquel S Linheiro

    Full Text Available Transposable elements are mobile DNA sequences that integrate into host genomes using diverse mechanisms with varying degrees of target site specificity. While the target site preferences of some engineered transposable elements are well studied, the natural target preferences of most transposable elements are poorly characterized. Using population genomic resequencing data from 166 strains of Drosophila melanogaster, we identified over 8,000 new insertion sites not present in the reference genome sequence that we used to decode the natural target preferences of 22 families of transposable element in this species. We found that terminal inverted repeat transposon and long terminal repeat retrotransposon families present clade-specific target site duplications and target site sequence motifs. Additionally, we found that the sequence motifs at transposable element target sites are always palindromes that extend beyond the target site duplication. Our results demonstrate the utility of population genomics data for high-throughput inference of transposable element targeting preferences in the wild and establish general rules for terminal inverted repeat transposon and long terminal repeat retrotransposon target site selection in eukaryotic genomes.

  1. In situ bioremediation (natural attenuation) at a gas plant waste site

    International Nuclear Information System (INIS)

    Ginn, J.S.; Sims, R.C.

    1995-01-01

    A former manufactured gas plant (MGP) waste site in New York was evaluated with regard to natural attenuation of polycyclic aromatic hydrocarbons (PAHs). Parent-compound concentrations of PAHs within an aquifer plume were observed to decrease with time subsequent to source removal of coal tar. Biotransformation-potential studies indicated that indigenous microorganisms in soil from the site were capable of degrading naphthalene and phenanthrene. A biochemical metabolite of phenanthrene degradation, 1-hydroxy-2-naphthoic acid (1H2NA), was tentatively characterized in coal-tar-contaminated soil from the site-based on liquid chromatographic retention time. Kinetic information was developed for the disappearance of phenanthrene and 1H2NA in nonspiked contaminated soil at the site. The Microtox trademark bioassay was used to evaluate toxicity trends in contaminated soil at the site. Results from the Microtox trademark indicated a decreasing trend in toxicity with respect to time in contaminated site soil. Research results were evaluated with regard to the National Research Council's guidelines for evaluating in situ bioremediation, and were used to enhance site characterization and monitoring information for evaluating the role of bioremediation as part of natural attenuation of PAHs at coal-tar-contaminated sites

  2. Why Sacred Lands Are Not Indivisible: The Cognitive Foundations of Sacralising Land

    Directory of Open Access Journals (Sweden)

    Richard Sosis

    2011-02-01

    Full Text Available Numerous political analysts have argued that conflicts over sacred land are intractable. These scholars maintain that sacred lands are psychologically perceived as indivisible, or alternatively, in the sociological tradition, their indivisibility is a social fact. Moreover, religious beliefs are viewed as stagnant and resistant to change. Consequently, resolving such conflicts is fraught with difficulty, and even if a truce could be imposed, it would be unstable and violence would eventually erupt. A cognitive and evolutionary account offers a less pessimistic view. Individuals do not conceive of sacred lands in the same way that they conceive of sacred space, such as cemeteries or houses of worship, or sacred objects, such as holy water or prayer beads. Unlike sacred space and objects, whose boundaries are clearly defined, conceptions of sacred land are typically abstract and may bear little resemblance to the contested physical land. While abstract notions of sacred land are indivisible and must remain intact, the physical land is not indivisible, and therefore there is often greater room for negotiation of sacred lands than is generally appreciated.

  3. Location and nature of calcium-binding sites in salivary acidic proline-rich phosphoproteins

    1981-01-01

    The location of the calcium-binding sites in the human acidic proline-rich proteins, salivary proteins A and C, was determined by equilibrium dialysis of the tryptic peptides with buffers containing 45 Ca. All the calcium-binding sites are located in the NH 2 -terminal tryptic peptide (TX peptide). The nature of the calcium binding sites in the TX peptide and native salivary proteins A and C, as well as dephosphorylated proteins was compared. Two types of sites can be distinguished in peptide TX. Type I sites have an apparent dissociation constant (K) of 38 μM and are responsible for the binding of 2.6 mol of Ca/mol of peptide. The corresponding figures for Type II sites are 780 μM and 5.3 mol of Ca/mol of peptide. In the native proteins, the amount of calcium bound at the type II sites decreases to 3.9 mol of Ca/mol of proteins A and C and K increases to 1100 μM. The amount of calcium bound at type I sites decreases to 1.5 mol/mol of protein A and 0.6 mol/mol of protein C, but there is no change in K. Dephosphorylation affects the calcium binding at both types of sites. The experiments indicate that the COOH-terminal parts of the native proteins affect the number and the nature of the protein calcium-binding sites. Proton and phosphorous NMR data demonstrate that β-COOH in aspartic acid, as well as phosphoserine, are part of the calcium-binding sites. The difference in calcium binding to salivary proteins A and C may be due at least partially to differences in the environment of one or more aspartic acids

  5. Nineteenth-century urbanization as sacred process: insights from German Strasbourg.

    Science.gov (United States)

    Steinhoff, Anthony J

    2011-01-01

    This article examines a crucial site for modernity’s encounter with religion during the long nineteenth century, albeit one largely ignored both by religious and urban historians: the modern big city. Drawing on evidence from Strasbourg, which joined the ranks of Germany’s big cities soon after the Franco-Prussian War, it points out first, that urbanization had a significant urban dimension. It altered the absolute and relative size of the city’s faith communities, affected the confessional composition of urban neighborhoods, and prompted faith communities to mark additional parts of the urban landscape as sacred. Second, while urban growth—both demographic and physical—frequently challenged traditional understandings of religious community, it also facilitated the construction of new understandings of piety and community, especially via voluntary organizations and the religious media. Thereby, urbanization emerged as a key force behind sacralization in city and countryside as the nineteenth century ended and the twentieth began.

  6. The Development of the Sacred Landscape of Saqqara in the Old Kingdom

    Science.gov (United States)

    Magli, Giulio

    2015-05-01

    Saqqara is one of the most important Necropolis in Egypt. In the course of the third millennium BC many Pharaohs choose Saqqara for their tombs. As a consequence the landscape constantly grew with the addition of new monuments, from the mastaba tombs of the first dynasty to the last pyramid of the Old Kingdom, that of Pepi II. The monuments were constructed respecting a series of topographical constraints which are not due to the morphology of the area but rather reflect symbolic - dynastic or astronomical - motivations. The analysis of these connections gives a better understanding of the choices made by the kings' architects in order to keep Maat - order - in the development of the site. Further, the way in which the sacred landscape came to be structured at the end of the Old Kingdom allows us to formulate a proposal for the possible location of the unique pyramid of the sixth dynasty which is still to be found: that of Userkare.

    Holtby, L.

    2003-01-01

    Implementation of the Siteview(TM) computer software package designed to capture and manage reclamation data, by Canadian Natural Resources Limited is reported. Use of this software, developed by Pelodon Computer Enterprises in Calgary, enables Canadian Natural Resources to track from a single file data from each of over 3000 sites from the pre-construction stage right through to the final reclamation. Having all data in a single file permits the company to track the number of Reclamation Certificate applications submitted and received for a specific time period, helping them to capture the liability reduction and rental reduction associated with those sites and in general, manage their reclamation program more efficiently. Tracking the reclamation sites is by specific Site Status Codes, which allow the company to quickly determine current status of each site. Budgeting for reclamation can also be planned more accurately based on the current status of sites. Siteview(TM) also manages waste disposal information in the Guide 50 Drilling Waste Disposal Notification forms by digitally inputting all required data such as waste disposal location, mud system, and the volume of mud, and generating reports based on various waste disposal parameters. The software is also used by environmental consultants to track client's well site operations, and display them graphically in their reports, thus providing value-added services to their clients

In general, validation is good, particularly for the Abyssal Plain model. Problems regarding uranium redox couples have been highlighted as have other areas requiring further consideration for building into the thermodynamic models. (author)

  14. The Characteristics and Social Function of the Tujia People’s Tima Sacred Songs

    Sacrificial songs possess a mysteri-ous cultural identity and have been widely popular in Chinese folklore; at the same time it has been difficult to identify and record them all. Therefore, in the cultural history of the Han Chinese people, folkloristic sacrificial songs ( including ‘calling-soul-back lyrics’ or certain incantations closely re-lated to the sacrificial songs) rarely have been re-corded and/or successfully handed on to our day and age. In times past however, the sacrificial po-etry chanted by ethnic priests/shamans in various rituals and ceremonies was respected, protected, and widespread among the various people. Among all sacrificial music belonging to various ethnic groups in China, the music of the Tujia people is quite unique. The traditional worship culture of the Tujia has been very rich, elaborate, and mysterious. Due to intense cultural beliefs, the sacrificial mu-sic of the Tujia had become quite colorful. This u-nique musical style and rhyme reflects the Tujia people’ s unique historic and artistic charm, cus-toms, and connotations. The ancestors of the Tujia first lived in the isolated Wuling Mountains. Due to their limited productivity level, they weren’ t a-ble to interpret most natural and social phenome-na; instead they viewed these phenomena accord-ing to their personal animistic beliefs. In recent years, however, scholars have conducted a lot of research on the Tujia religious beliefs, including their sacrificial customs and music. In this con-text, the tima shenge ( tima sacred songs ) have enjoyed meticulous scholarly research from the per-spectives of both cultural philosophy and communi-cation. This article tries to explore the origin and mysterious musical features of the tima sacred songs, in order to better understand their socio-cultural function:this in turn could allow for a bet-ter protection and promotion of these songs. Tima sacred songs are the most ancient and o-riginal type of the Tujia songs. Tima is a

    tourism operators, public sector managers and other stakeholders from the iconic World Heritage Site and tourism destination, Australia’s Great Barrier Reef (GBR) reveal how shifting ideologies and government policies increased pressures on nature, resulting in new alliances between stewards from...... the tourism sector and national and international organizations. These alliances were built on shared nature conservation values and successfully reduced increasing development pressures. Three distinct phases in this process emerged at the GBR, which were driven by personal values held by tourism industry...... representatives, and their recognition of tourism’s reliance on nature for business success. Changing mainstream ideologies and political values can erode World Heritage and Protected Areas, and recalibrate values – including the universal values on which World Heritage Sites depend – towards more anthropocentric...

    The sacred space becomes an important part of the spatial layout of Javanese society, as well as in most houses of the archipelago. This space is related to religious activities, highly respected and usually located in the main place. Kudus Kulon community is a part of Javanese culture in the northern coastal area of Java. Known as a devout Muslim society, sacred space in Kudus Kulon community house becomes an important thing to understand the culture of living in society. The research was conducted by looking at the religious activities of the community and how the space of activity is realized. The research was conducted by qualitative research method. In the Kudus Kulon community, sacred spaces are available in the house itself, in the community grup of houses, and around Kudus Kulon area. In every house, the sacred space can be found in Gedongan and extends to Dalem. In the community group of houses, the sacred space can be found in the neighbourhood praying area, while In Kudus Kulon area, it can be found in Mosque complex and Tower tomb. Physically sacred space is realized by raising the floor height of the space around it. In architectural view, the sacred space is seen on the elevation of the roof or roof angle. Spatially the sacred space occupies a central position and visually represented by a vertical orientation.

    2015-02-01

    Full Text Available More than a hundred rings bearing inscriptions are known from the territory of Roman Pannonia. Among these close to 30 artefacts can be regarded as rings displaying inscriptions of religious significance. Besides the Silvanus-rings, well-known to the archaeological research, some new groups of rings featuring sacred inscriptions can be distinguished according to the dedications. The aim of this paper is to analyse these objects and their religious backgrounds with the help of some archaeological, epigraphical and literary sources and to point out some of the questionable observations of the earlier research.

  3. Finding the Sacred Direction: Medieval Books on the Qibla

    Rius, M.

    2009-08-01

    Medieval Islamic scholars wrote a great number of books on the qibla, the Sacred Direction. These books had a huge readership and provided instructions for finding the direction of Mecca by either exact or approximate means. In principle, the qibla was a purely religious subject, but in practice its determination required the use of astronomy as an applied science. As so often, religion and politics had many points of contact and, in this case, it was generally political considerations that prevailed. Finally, the analysis of nautical charts can offer new perspectives. As yet, modern scholarship has not established the link between this area of study and the classical literature on this subject.

  4. Fusion: from sacred cow to white elephant?

    International Nuclear Information System (INIS)

    Wooldridge, J.

    1994-01-01

    Controlled thermonuclear fusion has the potential to supply lots of relatively cheap power relatively cheaply. It is also renewable and has public support. Because of this potential, fusion has been able to attract huge research funds. The four main research programmes, in Europe, USA, Japan and Russia, include cooperation on the International Thermonuclear Experimental Reactor, ITER. The siting of this reactor will be decided in 1998 and it is due to start operation in 2010. It should lead to a demonstration reactor, DEMO, after which a prototype commercial reactor is envisaged for 2030-2050. But this is too far away to solve some of the immediate energy problems such as carbon dioxide emissions and global warming. So even if the technical problems are solved, fusion may not be the wonder energy source when it finally arrives; the trend is away from centralised, high cost, high output generation. Fusion research has taken interest and money away from other alternatives such as tidal energy, fuel cells and photovoltaic cells. Photovoltaics in particular look more feasible than fusion and could be in place far sooner, but lack the funding for research. (UK)

    2017-08-01

    Sri Dalada Maligawa - the Temple of the Sacred Tooth Relic - is one of the most important pilgrim sites in Buddhist culture. It is the main part of the UNESCO World Heritage Site Sacred City of Kandy. Since the end of the 17th century the temple has been keeping the sacred tooth of the Buddha. Until now an accurate documentation of the temple with all its rich decorations is missing. The Temple is built in an area vulnerable to environmental factors like earthquakes or monsoon rains and was the target of terrorist attacks. To help preserving this important cultural heritage a research project was carried out. Main part of the project was a 3D-documentation of the entire temple by using Terrestrial-Laser-Scanning (TLS) and the creating of CAD-Plans. In addition to the documentation of the architecture several details were taken in high resolution by Structured-Light-Scanning (SLS). All data will be part of the digital archive of the temple and were used as a base for a general site monitoring, especially to observe cracks. Next to the mere documentation a transfer of knowledge was another aim of the project. In future most of the analysis of the scan data can be done by local specialists.

    1995-01-01

    The US Department of Energy (DOE) is both a trustee for the natural resources present on its properties and the lead response agency under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). As such, DOE is addressing the destruction or loss of those resources caused by releases of hazardous substances from its facilities (DOE 1991) and collecting data to be used in determining the extent of contamination at its facilities, estimating risks to human health and the environment, and selecting appropriate remedial actions. The remedial investigation/feasibility study (RI/FS) process is used to investigate sites and select remedial actions. A Natural Resource Damage Assessment (NRDA) process may be used to determine whether natural resources have also been injured by the released hazardous substances and to calculate compensatory monetary damages to be used to restore the natural resources. In FY 1994, the Savannah River Site (SRS) was chosen to serve as a demonstration site for testing the integrated NRDA framework and demonstrating how NRDA concerns might be integrated into the environmental restoration activities of an actual site that is characteristically large and complex. The demonstration project (1) provided a means to illustrate the use of complex analyses using real information on the specific natural resources of the SRS; (2) served as a vehicle for reinforcing and expanding the SRS staff's understanding of the links between the NRDA and RI/FS processes; (3) provided a forum for the discussion of strategic issues with SRS personnel; and (4) allowed the refining and elaboration of DOE guidance by benchmarking the theoretical process using real information and issues

    1996-01-01

    The K-25 Site UF 6 cylinder storage yards are used for the temporary storage of UF 6 normal assay cylinders and long-term storage of other UF 6 cylinders. The K-25 Site UF 6 cylinder storage yards consist of six on-site areas: K-1066-B, K-1066-E, K-1066-F, K-1066-J, K-1066-K and K-1066-L. There are no permanent structures erected on the cylinder yards, except for five portable buildings. The operating contractor for the K-25 Site is preparing a Safety Analysis Report (SAR) to examine the safety related aspects of the K-25 Site UF 6 cylinder storage yards. The SAR preparation encompasses many tasks terminating in consequence analysis for the release of gaseous and liquid UF 6 , one of which is the evaluation of natural phenomena threats, such as earthquakes, floods, and winds. In support of the SAR, the six active cylinder storage yards were evaluated for vulnerabilities to natural phenomena, earthquakes, high winds and tornados, tornado-generated missiles, floods (local and regional), and lightning. This report summarizes those studies. 30 refs

    1989-06-01

    One of the four natural analogue sites chosen for investigation by the British Geological Survey is the uranium mineralisation at Broubster, Caithness, Scotland. Naturally occurring uranium has been leached from a thin mineralised limestone horizon and has been carried by groundwater flow into a peat bog about 100m away. This process has probably been going on for at least 5000 years. Standard surveying, hydrogeological and geochemical methods have been applied in the investigation and analysis of the area. Selected samples of the mineralisation, peat soils and associated groundwaters have been examined in detail. This report summarises the main findings accumulated since 1968 when the site was first discovered, and provides a useful information base for further modelling work. (author)

    Research into natural analogues of radionuclide migration provide data for supporting computer codes that describe the processes of transport and retardation. Such models are appropriate to the far-fields of shallow and deep radioactive waste repositories. The objective of this research project was to define locations within the UK and abroad worthy of detailed investigation. Site investigations and evaluations were carried out at a number of UK localities. The main focus of this survey has been on uraniferous veins in places at near surface where transport of uranium into sediments has occurred. Several uranium rich mineralisations associated with granite margins were visited in Cornwall, Devon and along the Solway Firth coast in Scotland; the disused U mine at South Terras in Cornwall and the coastal site at Needle's Eye near Dalbeattie are confirmed as future study sites. Results to hand from the sediments of Loch Lomand warrant further measurements of iodine and bromine in fresh cores. (author)

    International Nuclear Information System (INIS)

    Kampbell, D.H.; Kittel, J.A.

    1996-01-01

    A remediation research study has been implemented at a jet fuel spill site on an island airport. A buried pipeline fracture several years ago resulted in a fuel spill exceeding 160,000 gallons. The site hydrogeology is a fragmented coral matrix with fresh water overlying more dense salt water. Water table fluctuations of about two feet occur once every twelve hours from tidal action. The research approach being pursued is to recover free-phase floating petroleum liquid using vacuum-mediated subsurface skimming wells. The vacuum will create an active vadose zone aeration to enhance aerobic biodegradation processes and vaporization of fuel. Once the floating fuel is removed, a natural bioventing action caused by tidal oscillations will complete remediation of the spill site

    R. L. Billingsley; V. Kuuskraa

    2006-03-31

    In order to predict the nature and distribution of natural fracturing, Advanced Resources Inc. (ARI) incorporated concepts of rock mechanics, geologic history, and local geology into a geomechanical approach for natural fracture prediction within mildly deformed, tight (low-permeability) gas reservoirs. Under the auspices of this project, ARI utilized and refined this approach in tight gas reservoir characterization and exploratory activities in three basins: the Piceance, Wind River and the Anadarko. The primary focus of this report is the knowledge gained on natural fractural prediction along with practical applications for enhancing gas recovery and commerciality. Of importance to tight formation gas production are two broad categories of natural fractures: (1) shear related natural fractures and (2) extensional (opening mode) natural fractures. While arising from different origins this natural fracture type differentiation based on morphology is sometimes inter related. Predicting fracture distribution successfully is largely a function of collecting and understanding the available relevant data in conjunction with a methodology appropriate to the fracture origin. Initially ARI envisioned the geomechanical approach to natural fracture prediction as the use of elastic rock mechanics methods to project the nature and distribution of natural fracturing within mildly deformed, tight (low permeability) gas reservoirs. Technical issues and inconsistencies during the project prompted re-evaluation of these initial assumptions. ARI's philosophy for the geomechanical tools was one of heuristic development through field site testing and iterative enhancements to make it a better tool. The technology and underlying concepts were refined considerably during the course of the project. As with any new tool, there was a substantial learning curve. Through a heuristic approach, addressing these discoveries with additional software and concepts resulted in a stronger set

    Fuel consumption has significantly increased due to the growth of the population. A solution to address this problem is the underground storage of natural gas. The first step to reach this goal is to select suitable places for the storage. In this study, site selection for the underground natural gas reservoirs has been performed using a multi-criteria decision-making in a GIS environment. The "Ordered Weighted Average" (OWA) operator is one of the multi-criteria decision-making methods for ranking the criteria and consideration of uncertainty in the interaction among the criteria. In this paper, Fuzzy AHP_OWA (FAHP_OWA) is used to determine optimal sites for the underground natural gas reservoirs. Fuzzy AHP_OWA considers the decision maker's risk taking and risk aversion during the decision-making process. Gas consumption rate, temperature, distance from main transportation network, distance from gas production centers, population density and distance from gas distribution networks are the criteria used in this research. Results show that the northeast and west of Iran and the areas around Tehran (Tehran and Alborz Provinces) have a higher attraction for constructing a natural gas reservoir. The performance of the used method was also evaluated. This evaluation was performed using the location of the existing natural gas reservoirs in the country and the site selection maps for each of the quantifiers. It is verified that the method used in this study is capable of modeling different decision-making strategies used by the decision maker with about 88 percent of agreement between the modeling and test data.

    2012-10-01

    Natural sources for novel insecticide molecules hold promise in view of their eco-friendly nature, selectivity, and mammalian safety. Recent progress in understanding the biology of insect olfaction and taste offers new strategies for developing selective pest control agents. We have isolated two natural insecticidal molecules from edible roots of Decalepis hamiltonii named Decalesides I and II, which are novel trisaccharides, highly toxic to household insect pests and stored-product insects. We have experimentally shown that insecticidal activity requires contact with tarsi on the legs but is not toxic orally. The insecticidal activity of molecules is lost by hydrolysis, and various sugars modify toxic response, showing that the insecticidal activity is via gustatory sites on the tarsi. Selective toxicity to insects by virtue of their gustatory site of action and the mammalian safety of the new insecticides is inherent in their chemical structure with 1-4 or 1-1 α linkage that is easily hydrolyzed by digestive enzymes of mammals. Decalesides represent a new chemical class of natural insecticides with a unique mode of action targeting tarsal chemosensory/gustatory system of insects.

    Hexavalent chromium (Cr(VI)) plumes are present in the 100 Area at the Hanford Site. Remediation efforts are under way with objectives of restoring the groundwater to meet the drinking-water standard (48 µg/L) and protecting the Columbia River by ensuring that discharge of groundwater to the river is below the surface-water quality standard (10 µg/L). Current remedies include application of Pump-and-Treat (P&T) at the 100-D, 100-H, and 100-K Areas and Monitored Natural Attenuation (MNA) at the 100-F/IU Area. Remedy selection is still under way at the other 100 Areas. Additional information about the natural attenuation processes for Cr(VI) is important in all of these cases. In this study, laboratory experiments were conducted to demonstrate and quantify natural attenuation mechanisms using 100 Area sediments and groundwater conditions.

    2013-04-01

    Full Text Available Despite of over 25 years of intensive technological efforts, sub-surface environment cleanup still remains a challenge, especially in case of highly contaminated sites. In this context, ion exchanger technologies could provide simple and effective solutions for heavy metal removal in water treatment. The challenge is finding exchanger able to operate in extreme natural environments or in situations involving natural interfering species such as inorganic ions. In this paper we exam the use of natural zeolites as versatile exchanger for environmental protection of coastal refinery's groundwater against pollution of Ni, Cd, Pb. The influence of particle diameter on clinoptilolite performances toward heavy metal removal is studied. Also, we evaluate the exchanger activities in condition of high ionic strength, commonly present in groundwater located under coastal petrol industries. The obtained results confirmed that ion exchangers could provide an effective solutions for remediation in complex environmental conditions.

  1. Natural resource management activities at the Savannah River Site. Environmental Assessment

    Energy Technology Data Exchange (ETDEWEB)

    1993-07-01

    This environmental assessment (EA) reviews the environmental consequences of ongoing natural resource management activities on the Savannah River Site (SRS). Appendix A contains the Natural Resources Management Plant (NRMP). While several SRS organizations have primary responsibilities for different elements of the plan, the United States Department of Agriculture (USDA), Forest Service, Savannah River Forest Station (SRFS) is responsible for most elements. Of the river scenarios defined in 1985, the High-Intensity Management alternative established the upper bound of environmental consequences; it represents a more intense level of resource management than that being performed under current resource management activities. This alternative established compliance mechanisms for several natural resource-related requirements and maximum practical timber harvesting. Similarly, the Low-Intensity Management alternative established the lower bound of environmental consequences and represents a less intense level of resource management than that being performed under current resource management activities. This alternative also established compliance mechanisms, but defined a passively managed natural area. The Proposed Action of this EA describes the current level of multiple-natural resource management. This EA reviews the proposed action, and the high and low intensity alternative scenarios.

  2. Natural responses to Quaternary climatic change in the Nevada Test Site region

    1993-01-01

    Migration of hazardous contaminants within geologic settings depends on natural processes. Climatic fluctuations can affect the magnitudes and rates of many of these processes. In any long-term environmental evaluation of natural processes, responses to climatic change must be considered. Four generalized categories of natural responses to Quaternary climatic change are recognized for the Nevada Test Site (NTS) region of southwestern Nevada and adjacent California: (1) biologic, (2) geomorphic, (3) hydrologic (including surface and subsurface) and (4) pedologic/diagenetic. Specific examples that correspond to the four categories illustrate the broad range of complex natural processes the are affected by climatic change. These responses dictate the potential effects of climatic change on contaminant transport, effects that are being examined by existing and planned environmental-restoration and waste-management programs within the region. Regulatory requirements for many of these programs include long-term (>10,000-year) waste isolation because of radiologic components. The purpose here is not to be exhaustive in documenting all known natural responses to climatic change in the NTS region, but rather to give a flavor of the scope of interdisciplinary and interrelated fields of Quaternary science that must be considered in evaluating the possible effects of climatic change on long-term environmental programs

  3. Image of Iraqis in The Cinema of Sacred Defense

    2012-03-01

    Full Text Available Regarding representational function of media, the current dissertation intends to examine the changes in the representation of the image of the Iraqis in the Sacred Defense Cinema. Iraqies have been pictured as the "Others" during last three decades. Due to the importance and role of sacred defense and its cinematic representations of "Self" and "Other" and thereby its contribution in the process of reconstruction of Iranian national identity this research is aimed at studying represented images of Iraqies and its changes during last three decades. To reach this objective I first examined the concept and theories of representation as stated by Richard Dyer and Stuart Hall. Then to complement Hall’s theories I referred to other thinkers in the field of identity theory, ‘self’ and ‘the other’ as stated. In the chapter on methodology I’ve benefited from a combination of the patterns presented by Kate Selbi, Ran Kallory and Rolan Bart to analyze the texts.The findings of this thesis demonstrates that in order to depict the Iraqis in the sixties verbal codes were primarily used whereas in the seventies and the eighties social and technical codes were most used respectively.In the first decade Iraqis were portrayed as those people who are imagined to be cruel, inhuman, in which the emphasis was laid on the impact of the Iraqi’s invasion. In the second decade we see Iraqi’s depicted as dumb and fat people having thick moustaches and rough voices and in the third we see this portrayal to be transformed where Iraqi’s are shown to be our Muslim brothers who have been forced to fight in the war. Having observed, examined and analyzed the films, we found out that when facing ‘the other’, i.e. the Iraqis, the metaphor of the boundary or border was used. This border is seen between ‘self’ and ‘the other’, i.e. the Iranians and the Iraqis in all the chosen movies on the Sacred Defense. In the first decade there was an objective

    Natural attenuation of mono- (BTEX) and polycyclic aromatic hydrocarbons (PAHs) was studied in groundwater at a former gas plant site over a distance of about 500 m. The contamination source was located within a 4-6 m thick succession of interbedded silt and sand (K{sub f} =1,4 .10{sup -7} m/s) at a depth of about 5-6 m below the surface. Groundwater flow times between source and the receiving surface waters were determined on the order of a few hundred years. The main contaminants were found to be benzene and naphthalene with concentrations up to 200,000 and 8,500 {mu}g/l, respectively. Over the past 9 years, concentrations within the contaminant plume have decreased and degradation of benzene was proven by compound specific carbon isotope analyses. In addition, sulphur isotope studies revealed that sulphate reduction has played a significant role. This was supported by ambient sulphate concentrations of 300-1,800 {mu}g/l at the site that are sufficient to sustain a long-term perspective for this process. In agreement with these physico-chemical conditions, no transfer of BTEX or PAHs from the plume into the nearby river has been observed. (orig.)

    Oil and Natural Gas (O&NG) development, production, infrastructure, and associated processing activities can be a substantial source of air pollution, yet relevant data and real-time quantification methods are lacking. In the current study, O&NG fugitive emissions of Volatile Organic Compounds (VOCs) were quantified in real-time and used to determine the spatial and temporal windows of exposure for proximate flora and fauna. Eleven O&NG sites on the Pawnee National Grassland in Northeastern Colorado were randomly selected and grouped according to production along with 13 control sites from three geographical locations. At each site, samples were collected 25 m from the wellhead in NE, SE, and W directions. In each direction, two samples were collected with a Gasmet DX4040 gas analyzer every hour from 8:00 am to 2:00 pm (6 hours total), July to October, 2016 (N=864). VOC concentrations generally increased during the 6 hr. day with the exception of N2O and were predominately the result of O&NG production and not vehicle exhaust. Thirteen of 24 VOCs had significantly different levels between production groups, frequently above reference standards and at biologically relevant levels for flora and fauna. The most biologically relevant VOCs, found at concentrations exceeding time weighted average permissible exposure limits (TWA PELs), were benzene and acrolein. Generalized Estimating Equations (GEEs) measured the relative quality of statistical models predicting benzene concentrations on sites. The data not only confirms that O&NG emissions are impacting the region, but also that this influence is present at all sites, including controls. Increased real-time VOC monitoring on O&NG sites is required to identify and contain fugitive emissions and to protect human and environmental health.

    The redox-potential, pH, chemical composition of fracture waters, and uraninite alteration associated with the Palmottu uranium mineralization (a natural analogue study site for radioactive waste disposal in southwestern Finland), have been studied. The data have been interpreted by means of thermodynamic calculations. The results indicate equilibrium between uraninite, ferric hydroxide and groundwater in the bedrock of the study site. Partially oxidized uraninite (UO 2 .33) and ferric hydroxide are in equilibrium with fresh, slightly acidic and oxidized water type, while primary uraninite is stable with deeper waters that have a higher pH and lower Eh. Measured Eh-pH values of groundwater cluster within a relatively narrow range indicating buffering by heterogenous redox-processes. A good consistency between measured Eh and analyzed uranium oxidation states was observed

    One of the four analogue sites chosen for investigation by the British Geological Survey is the uranium mineralization at Broubster, Caithness, Scotland. Naturally occurring uranium has been leached from a thin mineralized limestone horizon and has been carried by groundwater flow into a peat bog about 100 m away. This process has probably been going on for at least 5 000 years. Standard surveying, hydrogeological and geochemical methods have been applied in the investigation and analysis of the area. Selected samples of the mineralization, peat soils and associated groundwaters have been examined in detail. This report summarizes the main findings accumulated since 1968 when the site was first discovered, and provides a useful information base for further modelling work. 27 refs.; 12 plates; 40 figs.; 17 tabs

    In order to make assessment to the potential impact from accident of natural gas wells with hydrogen sulfide on the habitability of main control room of nuclear power plant (NPP), several assumptions such as source terms of maximum credible accident, conservative atmospheric conditions and release characteristics were proposed in the paper, and the impact on the habitability of main control room was evaluated using toxicity thresholds recommended by foreign authority. Case results indicate that the method can provide the reference for the preliminary assessment to external human-induced events during the siting phrase of NPP. (authors)

    Religion can have an important influence in moral decision-making, and religious reminders may deter people from unethical behavior. Previous research indicated that religious contexts may increase prosocial behavior and reduce cheating. However, the perceptual-behavioral link between religious contexts and decision-making lacks thorough scientific understanding. This study adds to the current literature by testing the effects of purely audial religious symbols (instrumental music) on moral behavior across three different sites: Mauritius, the Czech Republic, and the USA. Participants were exposed to one of three kinds of auditory stimuli (religious, secular, or white noise), and subsequently were given a chance to dishonestly report on solved mathematical equations in order to increase their monetary reward. The results showed cross-cultural differences in the effects of religious music on moral behavior, as well as a significant interaction between condition and religiosity across all sites, suggesting that religious participants were more influenced by the auditory religious stimuli than non-religious participants. We propose that religious music can function as a subtle cue associated with moral standards via cultural socialization and ritual participation. Such associative learning can charge music with specific meanings and create sacred cues that influence normative behavior. Our findings provide preliminary support for this view, which we hope further research will investigate more closely.

    José Refugio de la Torre Curiel

    2004-04-01

    Full Text Available This article  explores how historical  actors who interact in a sacred space create, confront and rebuild it in several ways. The author chose to study the Tlajomulco doctrina in the  late colonial period in order to analyze some changes undergone during the secularization of a Franciscan doctrine. He also studies the institutional dimension of the doctrine in order to understand how the Guadalajara diocese  and  the Franciscan province of Jalisco related to this particular sacred  space. The  analysis of quarrels over property and authority over the doctrine enables the author to discuss what this sacred  space meant to ministers and  parishioners  and  to conclude that each form of interaction with a sacred  space represents a particular way of understanding society and, more specifically, religiosity.

  13. Late Onset First Episode Psychosis Emerging as Delusional Misidentification of Familiar Sacred Places During a Holy Pilgrimage: A Case Report and Literature Review.

    The delusional misidentification syndromes (DMS) include a myriad of discrete but related syndromes, which have wide spectrum anomalies of familiarity. Several misidentification syndromes have been described in the psychiatric literature, the most common of these delusions are: the Capgras syndrome; the Fregoli syndrome; the syndrome of inter-metamorphosis; reduplicative paramnesia; and environmental reduplication. The reported case highlights the emergence of late onset first episode psychosis in a Middle Eastern 65-year-old female who has no previous psychiatric history. The nature of psychosis was mainly delusions of misidentification and persecution. DMS are relatively rare and occur predominantly in association with schizophrenia and affective psychosis. Between 25 and 40% are associated with organic conditions such as dementia, head injuries, brain tumors, and epilepsy. Only three cases of misidentification of sacred places have been reported previously in the literature. This case report is the first to present a DMS, emerging as a late onset first episode psychosis during the sacred journey of Hajj. The reported case highlights the importance of early recognition and treatment of mental health conditions that may appear de novo during the Hajj sacred journey. Readily available psychiatric resources, psychotropic medications, and psycho-education may be pivotal in ensuring mental well-being of pilgrims, which is fundamental to maintain the mental capacity required for completing these journeys.

  14. Landscape Archaeology and Sacred Space in the Eastern Mediterranean: A Glimpse from Cyprus

    Directory of Open Access Journals (Sweden)

    Giorgos Papantoniou

    2017-06-01

    Full Text Available This article aims to raise issues for discussion about the change in the use and concept of sacred landscapes, which were originally constructed in the era of the Cypriot kings (the basileis, but then continued to function in a new imperial environment, that of the rule of the Ptolemaic strategos and later of the Roman proconsul and the various Christian bishops. Our archaeological survey project in the Xeros river valley, titled ‘Settled and Sacred Landscapes of Cyprus’, reveals that these new politico-economic structures were also supported by the construction of symbolically charged sacred landscapes. Thus, while outlining the long history of the island as manifested from the diachronic study of Cypriot sacred landscapes, we identify three pivotal phases: first, the consolidation of the Cypriot polities and the establishment of a ‘full’ sacred landscape; second, the transition from segmented to unitary administration under the Ptolemaic and Roman imperial rule and the consolidation of a more ‘unified sacred landscape’; and finally, the establishment of a number of Christian bishoprics on the island and the movement back to a ‘full’ sacred landscape. Moving beyond the discipline of Cypriot archaeology, this contribution aims to serve as a paradigm for the implications that the employment of the ‘sacred landscapes’ concept may have when addressing issues of socio-political and socio-economic transformations. While it is very difficult to define or capture the concept of landscape in a pre-modern world, it offers a useful means by which to assess changing local conditions. We have also attempted to situate the term in archaeological thought, in order to allow the concept to become a more powerful investigative tool for approaching the past.

    Subsurface contamination by trichloroethene (TCE) was detected at a Michigan National Priorities List (NPL) site in 1982. The TCE plume resulted from the disposal of spent solvent and other chemicals at an industrial facility located in the eastern shore of Lake Michigan. TCE degradation products of three dichloroethene (DCE) isomers, vinyl chloride (VC) and ethene were present. The plume was depleted of oxygen and methanogenic at certain depths. Transects of the plume were sampled by slotted auger borings the year after the TCE plume was first discovered. Water samples were also taken from lake sediments to a depth of 12 m about 100 m offshore. Later samples were taken along the shoreline of the lake with a hand-driven probe. Later in 1998 water was taken from sediments about 3-m from the shoreline. The average concentration of each chemical and net apparent base coefficient between appropriate pairs of transects between the lower site and lakeshore were calculated. Loss rates were then calculated from an analytical solution of the two-dimensional advective-dispersive-reactive transport equation. Net apparent rate coefficients and a set of coupled reaction rate equations were used to extract the apparent loss coefficients. This study showed the field evidence for natural attenuation of TCE. - Field investigation of TCE contamination at a lake-shore site indicates that TCE is anaerobically degrading under ambient conditions

    An investigation was made on the actual concentrations of U, Th and Po in air-borne dust and soil around coal power stations, to study the effect of coal-ash disposal site on natural radioactivity of environmental samples. Samples were collected at a coal-ash disposal and its reference places. The results obtained are summaried as follows; (1) Concentrations of U, Th and Po in air-borne dust at the disposal place was nealy equal to those at the reference place. (2) Origin of those α-emitting elements in the dust was successfully deduced, on the basis of correlating concentrations of Sc and Cl elements in the dust. (3) It was inferred that elements of both U and Po in the dust at disposal site came from soil by about 80% and artificial origin such as exhausted gas by remainder. Almost all Th element were from soil. It was therefore concluded that effect of disposal site on radioactivity concentrations of dusts was negligible. (author)

  17. Technical Limitations in Merging Secular and Sacred Functions in Monumental Churches

    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.

  18. The supernatural characters and powers of sacred trees in the Holy Land.

    2007-02-25

    This article surveys the beliefs concerning the supernatural characteristics and powers of sacred trees in Israel; it is based on a field study as well as a survey of the literature and includes 118 interviews with Muslims and Druze. Both the Muslims and Druze in this study attribute supernatural dimensions to sacred trees which are directly related to ancient, deep-rooted pagan traditions. The Muslims attribute similar divine powers to sacred trees as they do to the graves of their saints; the graves and the trees are both considered to be the abode of the soul of a saint which is the source of their miraculous powers. Any violation of a sacred tree would be strictly punished while leaving the opportunity for atonement and forgiveness. The Druze, who believe in the transmigration of souls, have similar traditions concerning sacred trees but with a different religious background. In polytheistic religions the sacred grove/forest is a centre of the community's official worship; any violation of the trees is regarded as a threat to the well being of the community. Punishments may thus be collective. In the monotheistic world (including Christianity, Islam and Druze) the pagan worship of trees was converted into the worship/adoration of saints/prophets; it is not a part of the official religion but rather a personal act and the punishments are exerted only on the violating individual.

  19. Long term developments in irradiated natural uranium processing costs. Optimal size and siting of plants

    Thiriet, L.

    1964-01-01

    The aim of this paper is to help solve the problem of the selection of optimal sizes and sites for spent nuclear fuel processing plants associated with power capacity programmes already installed. Firstly, the structure of capital and running costs of irradiated natural uranium processing plants is studied, as well as the influence of plant sizes on these costs and structures. Shipping costs from the production site to the plant must also be added to processing costs. An attempt to reach a minimum cost for the production of a country or a group of countries must therefore take into account both the size and the location of the plants. The foreseeable shipping costs and their structure (freight, insurance, container cost and depreciation), for spent natural uranium are indicated. Secondly, for various annual spent fuel reprocessing programmes, the optimal sizes and locations of the plants are determined. The sensitivity of the results to the basic assumptions relative to processing costs, shipping costs, the starting up year of the plant programme and the length of period considered, is also tested. - this rather complex problem, of a combinative nature, is solved through dynamic programming methods. - It is shown that these methods can also be applied to the problem of selecting the optimal sizes and locations of processing plants for MTR type fuel elements, related to research reactor programmes, as well as to future plutonium element processing plants related to breeder reactors. Thirdly, the case where yearly extraction of the plutonium contained in the irradiated natural uranium is not compulsory is examined; some stockpiling of the fuel is then allowed some years, entailing delayed processing. The load factor of such plants is thus greatly improved with respect to that of plants where the annual plutonium demand is strictly satisfied. By including spent natural uranium stockpiling costs an optimal rhythm of introduction and optimal sizes for spent fuel

    2016-04-01

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

  4. Snail darters and sacred places: creative application of the endangered species act.

    Gilmer, Robert Andrew

    2013-11-01

    Rather than exploring how indigenous people have been alienated from resources by environmental policies, this paper explores how indigenous peoples have worked with environmental organizations to use the broad protections provided by environmental laws to protect cultural resources. The Eastern Band of Cherokee Indians, along with other concerned groups, partnered with environmentalists in opposing the destruction of the endangered snail darter's critical habitat by the Tennessee Valley Authority's Tellico Dam. The dam had been opposed by a shifting alliance of Cherokees, local farmers, trout fisherman, and environmentalists since it was announced in 1963. A previous lawsuit by this coalition delayed the project from 1972 to 1974 under the National Environmental Policy Act. The Endangered Species Act provided this coalition with a powerful tool for opposing the destruction of burial grounds and sacred village sites throughout the lower Little Tennessee River valley. The coalition of environmental organizations, Cherokees, and others was ultimately unsuccessful in stopping the dam from being built, but was successful in establishing a strict precedent for the enforcement of the Endangered Species Act. The lawsuit also created a space for the Eastern Band to negotiate for the return of Cherokee remains and halt the removal of any additional burials. In this situation, the strategic support of environmental regulation enabled the Eastern Band to exert some degree of control over the fate of cultural resources in the valley, and also demonstrates the significant role American Indian peoples played in one of the seminal events of the environmental movement during the 1970s.

    Full Text Available This year, on the 12th of July, there are four years since the passing away of the painter Dimitrie Gavrilean who, ,”through the unique impresion of his originality, early became an emblem of the school of painting of Iasi.” Born in Voroneţ, in 1942, Dimitrie Gavrilean attended ”Nicolae Grigorescu” Academy of Arts of Bucharest, being an eminent disciple of the master Corneliu Baba. The work in the creation workshop was combined with the vocation of teacher at the Faculty of Visual Arts and Design within ”G. Enescu” University of Arts of Iaşi, being a rector of this institution in the period 2000-2004. In the contemporary plastic landscape, the artistic work of the painter Dimitrie Gavrilean (1942-2012 from Iaşi occupies a special place. It mirrors the utmost of the autochthonous rural imaginary, the Romanian fundamental myths, the ancestral myths as well as the recently Christianized ones. His vision is specific to the Romanian Christianity and the Byzantine iconography. The language of Gavrilean’s paintings is one of symbols, by excellence. As Emil Staco rightfully observed, the entire work of art of master Gavrilean is ”a work of art of the symbols, of the metaphors rooted in the spirituality of the Romanian village of Bukovina, in the frescoes of Voroneţ and Humor Monasteries.” On the one hand, the painter did not content himself with illustrating only the ancestral mythical world by means of symbols with universal valences, but he got actively involved in the Christian valorization of mythical symbols. On the other hand, by integrating sacred symbols (the dove, the cock, winged characters, the wise old man, the architecture-church, the sun, Voroneţ blue of the Christian iconography of Byzantine tradition in paintings not necessarily religious, Dimitrie Gavrilean pushed his work of art to the border between sacred and profane, proving an extraordinary capacity of spiritualizing matter as well as of materializing the

    Full Text Available The article presents the first results of the comprehensive scientific research conducted on the Bulgar fortified settlement site in 2011. Samples for analysis were selected in the form of series of vertical columns from excavation walls. The species of trees used in the construction, the composition of the mud bricks and the bonding mortar, as well as the genesis of individual cultural layers have been identified. It has been found out that the settlement development and functioning had been reciprocating in nature: periods of intense habitation of its individual sections were followed by short stages of desolation. In all investigated soil columns with the cultural layers there are streaks consisting solely of phytoliths and cuticle casts. A possible explanation of the phenomenon may be that the plot was covered with layers of manure of significant length and capacity. This conclusion is debatable and requires further research.

    Green, R.T.; Rice, G.

    1995-01-01

    A field-scale percolation test is proposed for the Pena Blanca natural analog site near Chihuahua, MX. To aid in design of the field test, the V-TOUGH two-phase flow simulator was applied to model percolation of water through 8 to 10 m of partially saturated fractured tuff. The rock was characterized as a composite medium using measured hydraulic properties for the rock matrix and estimated values for the fractures. Measured matrix permeability varied over four orders of magnitude and fracture apertures were estimated to range from 10 to 1,000 μm. Water arrival times were predicted to vary between one day to 10,000 yr. The utility of the composite model and other representations of flow through fractured porous media can be tested using results from the field scale infiltration test data

    The Guaymas Basin (Gulf of California; depth, 2,000 m) is a site of hydrothermal activity in which petroliferous materials is formed by thermal alteration of deposited planktonic and terrestrial organic matter. We investigated certain components of these naturally occurring hydrocarbons as potential carbon sources for a specific microflora at these deep-sea vent sites. Respiratory conversion of [1- 14 C]hexadecane and [1(4,5,8)- 14 C]naphthalene to 14 CO 2 was observed at 4 degree C and 25 degree C, and some was observed at 55 degree C, but none was observed at 80 degree C. Bacterial isolates were capable of growing on both substrates as the sole carbon source. All isolates were aerobic and mesophilic with respect to growth on hydrocarbons but also grew at low temperatures (4 to 5 degree C). These results correlate well with previous geochemical analyses, indicating microbial hydrocarbon degradation, and show that at least some of the thermally produced hydrocarbons at Guaymas Basin are significant carbon sources to vent microbiota

    The long-term stability of near-surface containment systems designed for the management of radioactive wastes and residues contaminated with naturally occurring radionuclides are compared at the three different sites. The containment designs are: (1) a diked 8.9-m high mound, including a 3.2-m layered cap at a site (humid) near Lewiston, New York, (2) a 6.8-m-high mound, including a similar 3.2-m cap at a site (humid) near Oak Ridge, Tennessee, and (3) 4.8-m deep trenches with 3.0-m backfilled caps at a site (arid) near Hanford, Washington. Geological, hydrological, and biological factors affecting the long-term (1000-year) integrity of the containment systems at each site are examined, including: erosion, flooding, drought, wildfire, slope and cover failure, plant root penetration, burrowing animals, other soil-forming processes, and land-use changes. For the containment designs evaluated, releases of radon-222 at the arid site are predicted to be several orders of magnitude higher than at the two humid sites - upon initial burial and at 1000 years (after severe erosion). Transfer of wastes containing naturally occurring radionuclides from a humid to an arid environment offers little or no advantage relative to long-term stability of the containment system and has a definite disadvantage in terms of gaseous radioactive releases. 26 references, 3 figures, 4 tables

  10. Site-specific selfish genes as tools for the control and genetic engineering of natural populations.

    Site-specific selfish genes exploit host functions to copy themselves into a defined target DNA sequence, and include homing endonuclease genes, group II introns and some LINE-like transposable elements. If such genes can be engineered to target new host sequences, then they can be used to manipulate natural populations, even if the number of individuals released is a small fraction of the entire population. For example, a genetic load sufficient to eradicate a population can be imposed in fewer than 20 generations, if the target is an essential host gene, the knockout is recessive and the selfish gene has an appropriate promoter. There will be selection for resistance, but several strategies are available for reducing the likelihood of it evolving. These genes may also be used to genetically engineer natural populations, by means of population-wide gene knockouts, gene replacements and genetic transformations. By targeting sex-linked loci just prior to meiosis one may skew the population sex ratio, and by changing the promoter one may limit the spread of the gene to neighbouring populations. The proposed constructs are evolutionarily stable in the face of the mutations most likely to arise during their spread, and strategies are also available for reversing the manipulations.

    Full Text Available Abstract Tree worship is very common worldwide. This field study surveys the ceremonies and customs related to sacred trees in present-day Israel; it includes the results of interviews with 98 informants in thirty-one Arab, Bedouin, and Druze villages in the Galilee. The main results are: 1. Sacred trees were treated as another kind of sacred entity with all their metaphysical as well as physical manifestations. 2. There is not even one ceremony or custom that is peculiar only to a sacred tree and is not performed in other sacred places (such as a saint's grave or a mosque. 3. Few customs, such as: quarrel settling (= Sulkha, leaving objects to absorb the divine blessing and leaving objects for charity seem to be characteristic of this region, only. 4. In modern times, sacred trees were never recorded, in Israel, as centres for official religious ceremonies including sacrifices, nor as places for the performing of rites of passage. 5. There is some variation among the different ethnic groups: Kissing trees and worshipping them is more common among the Druze although carrying out burials under the tree, leaving water and rain-making ceremonies under them have not been recorded in this group. Passing judgments under the tree is more typical of the Bedouin in which the sacred trees were commonly used as a public social centre. Most of the customs surveyed here are known from other parts of the world. The differences between Muslims and Druze are related to the latter's belief in the transmigration of souls.

    1982-09-01

    Full Text Available While Malraux's life-long quest was to seek new values in man's perennial and shared struggle against an overwhelming fate, his early protagonist, particularly the assassin, turns to destruction and terrorism in a frenzied search for absolutes. This attempt to identify with the very fatality that has the power to destroy him is especially developed in Tchen, who embodies a despairing fascination with totalistic nihilism that Malraux must overcome in his search for a new notion of man. Tchen's initiation to murder in La Condition humaine marks a transgression of a taboo that thrusts him into what Georges Bataille calls the realm of the "sacred." His attempt to reconcile life and death by identifying with his victim irredeemably isolates Tchen from other, uninitiated men. Transformed by murder, he leaves the reality of revolution for the inhuman world of cosmic existence and individual death. Seeking to escape the human condition, he becomes obsessed with killing Chang-Kai-shek in order to kill himself and thereby "possess" his fate. But the illusion of such an escape dies with Tchen. Even his admiring disciples repudiate his nihilistic temptation as Malraux begins to seek in human fraternity the foundations of a new humanism.

    Full Text Available The following article presents the development of the bow and arrow, and its important role in the history of Iran. The bow always played an important role not only on the battlefield, but also in hunting. It was also considered as a sacred weapon and additionally a royal symbol. Bow and arrow were considered as a superior weapon in comparison with other types of weapons because one could fight with them at a safer distance as one offered by swords, maces and axes. The first part of the article presents a short history of the bow in Iran. Based on historical Persian manuscripts, the next part explains the structure of the composite bow and the materials used for making it. The third part describes some types of bows based on the material, place of production, the usage, and bow type based on the length of the bow and the arrows. The following part talks about different types of arrows based on morphology of arrowheads, the type of plume/feather, the material of the shaft, the material of the arrowhead, the length of arrows, the target of arrows, the place of production of arrowheads and terms for describing its different features of an arrowhead. Then, the article talks about different types of thumb rings, bowstrings, quivers and bow cases and arrow guides for shooting short arrows. The next part discusses different principles of archery as explained in Persian manuscripts. Finally the article describes different archery targets.

    Full Text Available The world united in unprecedented ways in mourning the global icon Nelson Mandela, an emotionally charged historical event in which digital visuality played an influential role. The memorial service for Nelson Mandela on Tuesday, 10 December 2013, gathered dignitaries and celebrities from around the world at the First National Bank Stadium in Johannesburg, to mourn the passing of Madiba and to celebrate his life work. At the Grand Parade in Cape Town, the event was broadcast on large public screens, followed by live music performances and narrowcast interaction with the audience. Building on recent research on public screens during global media events, this article addresses the mediated mourning rituals at the Grand Parade in terms of a sacred drama. Focusing on social relationality, the article discusses how digital visuality mediated a sense of global communitas, thus momentarily overcoming historical frictions between the global north and the global south, while expanding the fame of Madiba. Paying attention to the public display of visual memory objects and the emotional agency of images, it argues that digital visuality mediated social frictions between the living and the dead, while recasting a historical subject as a historical object. The article further discusses how digital visuality mediated cultural frictions of apartheid and xenophobia, through the positioning of Mandela in the pantheon of Pan-African icons, thus underlining the African origin of this global icon. The analysis is based on ethnographic observations and experiences in Cape Town.

    The covalent attachment of polyethylene glycol (PEG) to therapeutic proteins can improve their physicochemical properties. In this work we utilized the non-natural amino acid p-azidophenylalanine (pAzF) in combination with the chemoselective Staudinger-phosphite reaction to install branched PEG chains to recombinant unglycosylated erythropoietin (EPO) at each single naturally occurring glycosylation site. PEGylation with two short 750 or 2000 Da PEG units at positions 24, 38, or 83 significantly decreased unspecific aggregation and proteolytic degradation while biological activity in vitro was preserved or even increased in comparison to full-glycosylated EPO. This site-specific bioconjugation approach permits to analyse the impact of PEGylation at single positions. These results represent an important step towards the engineering of site-specifically modified EPO variants from bacterial expression with increased therapeutic efficacy.

    2016-11-01

    Full Text Available This article studies the meaning of water and gender in the North Indian pilgrimage to the sacred river Ganges. It joins the recent criticism in anthropology concerning the nature/culture divide and aims to transcend that divide by focusing on water, not apart from but as part of social life. Assuming that water’s sociality is gendered, the authors look at how both the river water—itself as a landscape material—and the pilgrims’ engagements with that water are gendered. Starting from the central question: How do men’s and women’s ritual engagements with the sacred female river water (mutually construct social life? The article investigates men’s and women’s ritual use of water at different sites. It focuses on more than the central pilgrimage shrine and links the sacred river site to people’s homes to know how the moving river water, collected by pilgrims at the shrine, is used in water rituals back home. Trying to counterbalance the male and scriptural bias which is prominent in the literature on Ganges’ pilgrimage sites, the pilgrimage is studied from the perspective of lived religion that takes people’s embodied practices and sensory experiences of nature into account as well as people’s everyday life. By showing how men’s and women’s rituals differ and complement each other, it argues that men’s rituals at the pilgrimage site and women’s rituals at home serve the recreation of the family in a paired way. The argument is built on longitudinal and multi-sited ethnographic fieldwork at the Ganges river shrine in Haridwar (Uttarakhand and pilgrims’ residence in Udaipur (Rajasthan.

  17. Are Brands Postmodern Relics? Taking a Closer Look at New Sacred Objects

    Directory of Open Access Journals (Sweden)

    Stéphane DUFOUR

    2011-01-01

    Full Text Available Ever since the Church lost its monopoly on the sacred, no longer able to solely determine its form or contents, the social sphere has gradually taken over this value, applying it to new human and social objects. As a result, the modes of expression of the sacred have multiplied, along with the subjective and intimate experiences of modern individualism. Among the vast number of potential manifestations of this value, to which almost everything now seems to aspire, this paper will concentrate on commercial brands as vectors of meaning, with the hypothesis that some of them seek to position themselves, in postmodern society, as new figures of the sacred. This area of study is close to that of the sociologist Adam Arvidsson, when he describes brands as religious objects. If brands are less interested in selling products than in creating an affective experience, Arvidsson assimilates them to modern relics. However, this paper goes beyond metaphors, to examine the rhetorical strategies (discourse, rituals, representations, imagery through which brands construct meaning around sacred objects. Situated between a branch of marketing which concentrates on sacralising commercial products, and a theory popular in the English-speaking world, which has illustrated how the media work to sacralise products and brands, this paper uses a communicational approach to analyse the construction of meaning, by brands looking to make themselves (appear sacred.

    Nature and culture are elements that play an important role in the development of a place. Sites of Walisanga spread all over Java since in 16 century. Muslim communities respect respect for these sites. These sites have become an attractive destination of religious tourism on the North Coast of Java. Some of these sites are very close to nature and as a part culture. Shinto shrines and Buddhist temples in Japan are the examples of the master pieces of indigenous architecture which are still maintained very well. The Japanese religious sites with the beautiful architecture and landscape in the culture format have been successfully attracting tourist from all over the world. This paper aims to determine the potency and problems associated with the development of spatial harmony between the nature and culture on the Walisanga religious sites in Indonesia by conducting a dialogue with best practices cases in Japan. This study used descriptive analysis methods. The result showed that, there are similarities between Indonesian and Japan in treating cultural heritage assets. Indonesian government gives quite significant roles to public to participate in preserving cultural heritage. Japan government has given support through the modern technology and funding, assets registration, maintenance and protection, and the assets management. Creating the harmony between nature and culture is necessary to enhance performance, facilities and infrastructure.

    Full Text Available Reliable estimates of forest site productivity are a central element of forest management. The model of height-diameter relationship of dominant trees using algebraic difference approach (ADA is a commonly used method to measure site productivity of natural uneven-aged stands. However, the existing models of this method do not recognize site type or sample plot specific variability in height curves; thus, it cannot be effectively used to estimate site type or sample plot-related site productivity for natural uneven-aged stands. Two primary subject-specific approaches, ADA with dummy variable (DV (ADA + DV and ADA with combination of dummy variable and nonlinear mixed-effects modelling (CM (ADA + CM, were proposed for height–diameter modelling. Height–diameter models developed with ADA, ADA + DV and ADA + CM were compared using data from 4161 observations on 349 permanent sample plots of four major natural uneven-aged pure stands (Spruce, Korean Larch, Mongolian Oak, and White Birch in northeastern China. It was found that models developed with ADA + CM provided the best performance, followed by the models with ADA + DV, and the models developed with ADA performed the worst. Random effects at the plot level were substantial, and their inclusion greatly improved the model’s accuracy. More importantly, the models developed with ADA + CM provide an effective method for quantifying site type- and sample plot-specific forest site productivity for uneven-aged pure stands.

    The open water bodies as a component of the biosphere serve as the accumulators of artificial radionuclides generated during the nuclear explosions; therefore their radioactive contamination needs to be registered. The assessment of the environmental radioactive contamination consequences for the natural populations of organisms living in water bodies is of particular importance. Chironomini (Diptera, Chironomidae) play an important role as they are a significant component of water and air biocenoses and provide the self-cleaning of water bodies and food chains of industrial fish and bird. Chironomini have been chosen to be a model for the UNESCO International Program titled 'Man and Biosphere' and are used as the biologic indicator for ecological studies of anthropogenic influence on water bodies. The study of Chironomini natural mutagenic process and its alteration due to the radioactive contamination of water bodies is of extreme scientific interest and can serve as the indicator of the scale of genetic damage of water organisms. This work presents the data on natural populations of Chironomini of former STS water bodies: Shagan Lake, Balapan Lake, the artificial water body on the Karazhyra Coal Field, the backwater near the Shagan River, Balykty col Lake, etc. The analysis of morphology and caryotype of Camptochironomus sp. S (S - larvae have been sampled from the Semipalatinsk Test Site) showed that this is a new species as compared to studied species (C. tentans, C. pallidivittatus) of Camptochironomus subfamily. The caryotype Camptochironomus sp. S differs sharply from the caryotypes of other Camptochironomus species due to its strong hetero chromatization of centromeric discs. The immediate molecular analysis of genome DNA of Camptochironomus sp. S larvae sampled from Shagan Lake was performed: the total DNA of larvae of this species was obtained, nucleonic sequences of genes of cytochrome B (Cyt B) and cytochrome I (COI) were determined using methods of

    The British Geological Survey has been carrying out a research investigation of the Needle's Eye site at Southwick on the Solway coast in south-western Scotland. This study of a naturally radioactive geochemical system has the aim of improving our confidence in using predictive models of radionuclide migration in the geosphere. This summary report describes results from the integrated use of hydrogeological, mineralogical and geochemical techniques applied to the study of the transport and distribution of uranium. Pitchblende veins exposed in the cliffs are a major source of soluble uranium in ground-waters flowing into organic-rich post-glacial flood plain and intertidal mudflat deposits. Organic matter both living and dead has played a key role in the retardation of uranium in these sediments. Chemical transport modelling of the uranium dispersion/retardation is described and the implications for performance assessment work are discussed. Computer codes used: CHEMVAL (thermodynamic data base constants). CHIMERE (chemical equilibrium code). METIS (flow code). PHREEQE (chemical equilibrium code). STELE (coupled chemical transport code)

    An integrated field, laboratory, and modeling study of the Pena Blanca (Chihuahua, Mexico) natural analogue site is being conducted to evaluate processes that control the mobilization and transport of radionuclides from a uranium ore deposit. One component of this study is an evaluation of the potential for radionuclide transport through the unsaturated zone (UZ) via a seepage study in an adit at the Nopal I uranium mine, excavated 10 m below a mined level surface. Seasonal rainfall on the exposed level surface infiltrates into the fractured rhyolitic ash-flow tuff and seeps into the adit. An instrumented seepage collection system and local automated weather station permit direct correlation between local precipitation events and seepage within the Nopal I +00 adit. Monitoring of seepage within the adit between April 2005 and December 2006 indicates that seepage is highly heterogeneous with respect to time, location, and quantity. Within the back adit area, a few zones where large volumes of water have been collected are linked to fast flow path fractures (0-4 h transit times) presumably associated with focused flow. In most locations, however, there is a 1-6 month time lag between major precipitation events and seepage within the adit, with longer residence times observed for the front adit area. Seepage data obtained from this study will be used to provide input to flow and transport models being developed for the Nopal I hydrogeologic system.

    1999-01-01

    In some parts of Germany substantial areas have been contaminated with naturally occurring radioactive material (NORM) from past activities. Particularly important are residues from past uranium mining operations (WISMUT), being subject to a massive 13 billion DM cleanup program, as well as other mining activities dealing with elevated levels of NORM. Decisions concerning the necessity and the required extent of remediation measures are based on a combination of criteria addressing limitations of maximum individual doses for critical groups as well as the optimization of the net benefit from the remediation. From these basic requirements secondary criteria have been derived, defining, for example, soil contamination levels below which a remediation is not required. The optimization analyses, carried-out to identify optimal remediation options, address radiological risks as well as short and long term costs within a cost-benefit analysis framework. Other relevant factors of influence, e.g. chemical risks or ecological damage, are incorporated as well. Comprehensive methodologies utilizing probabilistic methods have been developed to assess site conditions and possible remediation options on this basis. (author)

    Full Text Available Sacred groves are forest patches conserved by the local people through religious and cultural practices. These groves are important reservoirs of biodiversity, preserving indigenous plant species and serving as asylum of Rare, Endangered and Threatened (RET species. The present study was carried out in Muppuram coastal sacred grove of Kanyakumari district to reveal the plant diversity, structure and regeneration pattern of trees using quadrate method. About 102 plant species were recorded from the total area (0.2 ha of the grove studied. The vegetation of the grove clearly indicates tropical dry evergreen forest. Malvaceae was the dominant family. Young plant species were dominating than older ones (> 160 cm. To avoid the rapid environmental degradation of the sacred grove, conserving the groves is urgent and it is necessary to conduct more researches on this grove as well as other groves of the district.

    International organizations recognize the importance of sacred groves and place them into the context of sustainable development and also emphasize to conserve biodiversity through protection of sacred groves and sties. The significance of medicinal plants from Himalayan region is well known to the world. Therefore, present study was conducted in identified sacred groves of Kumaon Himalaya to investigate and document the utilization of medicinal plants by various local communities and tribal people. The study was conducted during 2008-2011 in four seasons of the year. Information was collected from 70 locals from different sacred groves by using free listing interviews with randomly selected informants and semi-structured questionnaires; plant specimens were collected, identified and deposited at the CSIR-NBRI herbarium (LWG), Lucknow, India. Seven sacred groves viz., Dhwaj, Haat Kali, Hokra, Malay Nath, Nakuleshwar, Narayan Swami Ashram and Patal Bhuvneshwar were identified from the Pithoragarh district of Kumaon Himalaya. 89 medicinal plants belonging to 52 families and 77 genera of which, 2 are lichens, 4 are pteridophytes, 3 are gymnosperms and remaining 80 plant species are angiosperms. 6 plant species are reported with new therapeutic uses for the first time in this paper. Highest informant׳s consensus factor value was found in liver disorder (0.55) and least by body pains (0.23). 55 ethnomedicinal plants are showing 100% fidelity level against various diseases. Sacred groves in Kumaon region of Indian Himalaya are rich sources and best repository of ethno-medicinally important plants with many rare, endangered and threatened species. It is an excellent example of unique traditional way of in situ conservation of different plant species. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2013-09-01

    Conflicts over sacred values may be particularly difficult to resolve. Because sacred values are nonfungible with material values, standard attempts to negotiate, such as offering material incentives to compromise, often backfire, increasing moral outrage and support for violent action. We present studies with Palestinians in the West Bank and Gaza demonstrating three other ways sacred values may make conflict more intractable, focusing on what we call devoted actors, people who regard issues central to the Israel-Palestine conflict as sacred values. We show that devoted actors (1) were less amenable to social influence, (2) perceived conflict-related events in the past as well as expected events in the future to be temporally closer, and (3) were blind to individual opportunities to escape the conflict. These results suggest that sacred values may affect decision making in a number of ways, which, when combined, contribute to common defense and continuation of conflict. © 2013 New York Academy of Sciences.

  11. Symbolic structure in the architecture of the temple – introduction into theology of the sacred art

    Directory of Open Access Journals (Sweden)

    Jerzy Uścinowicz

    2014-11-01

    Full Text Available Symbol has always been an intrinsic part of a person. The human being – homo religiosus – is by nature also a homo symbolicus, who thinks and feels symbolically, who lives symbolically. In the domain of sacrum, in the temple, life is realized through holy symbols.In the past, this was directly reflected in the architecture and in the art of all religions. They have their special compensation in the temple and vice versa; the temple is a concrete manifestation of the function of a symbol. Thanks to them, art could manifest itself, could naturally pass from the level of aesthetics to the level of religion. Nowadays we face a kind of crisis of symbol in the sphere of art, certain reluctance towards symbols. The language of symbols seems to be dying out.Two thousand years of history of Christianity proved that a main criterion of a value of church architecture was not based on architectural precursors. This architecture was sacred because it was a carrier of a „truth of God” and – like a liturgical mysterion and iconography art – it was a theological comment. It was a codified language of the transposes of religions essences and orders, into the form of architectural expression. This was in a East Christianity and this happens there up to this day.One of the proofs to confirmate this thesis is an example of dome. It has been in existence since the beginning of forming the traditional architecture structure of the orthodox temple; it manifested symbolical and archetype essence – as an interior space and as an exterior form. In the history of architecture as well as the history of religion it had precisely defined symbolic meanings. They designated its significance in the temple, they gave rise to its long duration in the history, and eventually they gave it a status of an essential element, an everlasting witness of Divine mystery”. Presentation of this essence and orders constructs indispensable context to a value of the

    Magnetic properties of environmental samples are very sensitive in detecting strongly magnetic compounds such as magnetite and maghemite and can help in assessing concentration and grain-size distribution of these minerals. This information can be helpful in estimating, e.g., the source of pollutants, monitoring pollution load, or investigating seasonal and climatic effects. We studied magnetic properties of particulate matter ( PM1, PM2.5, PM10 and TSP - total suspended particles), collected over 32-48 hours in a small settlement in south Bohemia during heating and non-heating season. The site is rather remote, with negligible traffic and industrial contributions to air pollution. Thus, the suggested seasonal effect should be dominantly due to local (domestic) heating, burning wood or coal. Our results show typical differences in PMx concentration, which is much higher in the winter (heating) sample, accompanied by SEM analyses and magnetic data oriented on concentration and grain-size distribution of magnetite/maghemite particles. While PM concentrations are significantly higher in winter, differeces between concentration of Fe-oxides in summer and winter are not that significant. In both summer and winter, more FeO was in coarser PM10 than in the finer fractions. This is in good agreement with SEM observations. Grain-size sensitive parameters are different for summer and winter PMx samples, suggesting different source of PMx. It seems that domestic heating does not produce significant amount of FeO oxides in this site, its contribution during heating season compensates for the decay from natural sources (and/or agriculture) during summer. Our results prove the high sensitivity of magnetic methods in terms of concentration of ferrimagnetic Fe-oxides. However, their potential to discriminate unambiguously their origin is still questioned. This study is supported by the Czech Science Foundation through grant #P210/10/0554.; Fig. 1.

    Florida invested in preserving the Tequesta Indians' "Stonehenge-like" site along the Miami River. Direct observation, and telecast reports, show that a strong association exists between this area and Native American place names, hurricanes, tornados, a waterspout, and other nearby phenomena. Electromagnetic stimulation of human nervous systems in areas like these, discernable by appropriately sensitive individuals when these types of events occur, could plausibly account for some correct "predictions" of events like earthquakes. Various sensory modalities may be activated there. It may be important to understand other historic aspects associated with cultural artifacts like Miami's Tequesta remains. If it also generates instrumentally detectable signals that correlate with visual, "auditory," or nerve ending "tinglings" like those cited by the psychiatrist Arthur Guirdham in books like his Obsessions, applied physicists could partly vindicate the investment and also provide a net return. Society and comparative religious study may benefit.

    Full Text Available In this text, I discuss Vaslav Nijinsky's choreography of Le Sacre du Printemps (henceforth Sacre as it appears in the light of primary source materials from 1913. By focusing on the unique challenges Nijinsky posed to his dancers in terms of movement style and composition, I contest many of the frequently-heard claims made about this work, particularly its danced component, and argue that Nijinsky's choreographic ideas challenged both dancers and critics by questioning the ontological qualities of (art dance in contemporary discourse.

    1997-09-01

    Work is currently underway within the Underground Test Area subproject of the US Department of Energy/Nevada Operations Office Environmental Restoration Program to develop corrective action plans in support of the overall corrective action strategy for the Nevada Test Site as established in the Federal Facility Agreement and Consent Order (FFACO, 1996). A closure plan is currently being developed for Pahute Mesa, which has been identified in the FFACO as consisting of the Western and Central Pahute Mesa Corrective Action Units. Part of this effort requires that hydrogeologic data be compiled for inclusion in a regional model that will be used to predict a contaminant boundary for these Corrective Action Units. Hydrogeologic maps have been prepared for use in the model to define the nature and extent of aquifers and confining units that might influence the flow of contaminated groundwater from underground nuclear tests conducted at Pahute Mesa. Much of the groundwater flow beneath Pahute Mesa occurs within lava-flow aquifers. An understanding of the distribution and hydraulic character of these important hydrogeologic units is necessary to accurately model groundwater flow beneath Pahute Mesa. This report summarizes the results of a study by Bechtel Nevada geologists to better define the hydrogeology of lava-flow aquifers at Pahute Mesa. The purpose of this study was twofold: (1) aid in the development of the hydrostratigraphic framework for Pahute Mesa, and (2) provide information on the distribution and hydraulic character of lava-flow aquifers beneath Pahute Mesa for more accurate computer modeling of the Western and Central Pahute Mesa Corrective Action Units.

  19. Catalytic Ozonation of Toluene Using Chilean Natural Zeolite: The Key Role of Brønsted and Lewis Acid Sites

    Full Text Available The influence of surface physical-chemical characteristics of Chilean natural zeolite on the catalytic ozonation of toluene is presented in this article. Surface characteristics of natural zeolite were modified by acid treatment with hydrochloric acid and ion-exchange with ammonium sulphate. Prior to catalytic ozonation assays, natural and chemically modified zeolite samples were thermally treated at 623 and 823 K in order to enhance Brønsted and Lewis acid sites formation, respectively. Natural and modified zeolite samples were characterised by N2 adsorption at 77 K, elemental analysis, X-ray fluorescence, and Fourier transform infrared (FTIR spectroscopy, using pyridine as a probe molecule. The highest values of the reaction rate of toluene oxidation were observed when NH4Z1 and 2NH4Z1 zeolite samples were used. Those samples registered the highest density values of Lewis acid sites compared to other samples used here. Results indicate that the presence of strong Lewis acid sites at the 2NH4Z1 zeolite surface causes an increase in the reaction rate of toluene oxidation, confirming the role of Lewis acid sites during the catalytic ozonation of toluene at room temperature. Lewis acid sites decompose gaseous ozone into atomic oxygen, which reacts with the adsorbed toluene at Brønsted acid sites. On the other hand, no significant contribution of Brønsted acid sites on the reaction rate was registered when NH4Z1 and 2NH4Z1 zeolite samples were used.

    sacred sites. This sacred quality is achieved by installing crucifixes, altars and niches for virgins and saints. These symbols of folk religion not only adorn public sites, but also offer protection, serve as mnemonic devices and manage spatial liminality -all this in a chaotic city where public spaces are considered to be almost extinct. These elements -faces, proper names, common religious symbols- mark "anonymous" urban spaces, generating meaning and memory for inhabitants. In this fashion, public spaces become a scenario for projecting personal elements of neighborhood groups.

  1. Integrating Sacred Knowledge for Conservation: Cultures and Landscapes in Southwest China

    Full Text Available China is undergoing economic growth and expansion to a free market economy at a scale and pace that are unprecedented in human history. This is placing great pressure on the country's environment and cultural diversity. This paper examines a number of case histories in China, focusing on the culturally varied and ecologically diverse southwest region of the country. We show how developments in recent Chinese history have devalued and in some cases eliminated indigenous knowledge and practices in the quest to strengthen the centralized state. Despite these changes, more than 30 ethnic minorities live in southwest China. For generations these peoples have maintained landscapes through traditional land use and cultural practices. This indigenous knowledge places a high value on protecting forests, landscapes, and water catchments while preserving biodiversity. These values are maintained through religious beliefs, hunting taboos, and the protection of sacred sites. We advocate a conservation policy for China that includes the indigenous knowledge and values needed to maintain the environment and the traditional cultures themselves. There are seminal signs that the government is beginning to support indigenous cultures in China. The Organic Law of 1998 granted villages the legal right to self-government and gave indigenous communities greater responsibility for land and resource use. Traditional and indigenous cultural products have also developed a market and an economic value within a growing tourism industry. In many cases, however, indigenous people remain isolated from major land-use and conservation decisions that are the result of centrally planned policy. Meanwhile, frequent oscillations in forest policy and land tenure insecurity since the 1950s have led to the erosion of many local institutions and the loss of indigenous knowledge. We suggest that the long-term viability of the environment requires an interactive approach that involves

  2. The Ganges and the GAP: An Assessment of Efforts to Clean a Sacred River

    Full Text Available For centuries, the Ganges River in India has been the locus of sacred rites for the Hindus. The religious significance of the Ganges is physically manifested in ghats (stepped landings that form the land-water interface. Besides serving as a site for religious bathing and cremation, the ghats are also tied to people’s livelihoods and are an inseparable part of their daily lives. Today, the increasingly urbanized Ganges basin sustains more than 40 percent of India’s population. At the same time, industrialization and the pressures of a growing population along its banks have contributed to alarming levels of pollution in the river. In 1985, the federal government of India launched the Ganga Action Plan (GAP with the primary objective of cleaning the river. However, characterized by centralized planning and control with little public participation, the GAP had limited impact. In 2011, the government launched yet another clean up program—the National Ganga River Basin Project—with support from the World Bank. In this paper, we take a closer look at the programs to highlight the tenuous relationship between the need for ‘efficient’ management of environmental problems and public participation. Can public participation fit into the technocratic model that is often adopted by environmental programs? What approaches to participation kindle authorship and empowerment among those who share a deep relationship with the river and the ghats? Can religious practices be accommodated within scientific frameworks of adaptive management and resilience? We argue that rethinking the relationship between pollution control programs and participation is crucial for any effort to clean the Ganges, restore its waterfront, and catalyze broader regeneration in the Ganges basin.

    The Bitumount Provincial Historic site is the location of 2 of the world's first oil-extracting and -refining operations. Despite hydrocarbon levels ranging from 330 to 24 700 mg·(kg soil) -1 , plants have been able to recolonize the site through means of natural revegetation. This study was designed to achieve a better understanding of the plant-root-associated bacterial partnerships occurring within naturally revegetated hydrocarbon-contaminated soils. Root endophytic bacterial communities were characterized from representative plant species throughout the site by both high-throughput sequencing and culturing techniques. Population abundance of rhizosphere and root endosphere bacteria was significantly influenced (p hydrocarbon-degrading genes (CYP153 and alkB) were significantly affected (p < 0.05) by the interaction of plant species and sampling location. Our findings suggest that some of the bacterial communities detected are known to exhibit plant growth promotion characteristics.

    Full Text Available The nature of discourse in public culture has changed significantly if not noticeably in just the past few decades. The Sethusamudram Shipping Canal Project (SSCP intended to create a commercial shipping lane between India and Sri Lanka demonstrates the nature of this change in discourse, which seems focused around the convergence of traditional news media and public commentary through the medium of the Internet which increases the reach of news as well as the speed with which that news arrives to its audience. Just two decades earlier, at a time when the Internet was very young, many of the same political parties and government agencies involved with the SSCP were also involved in the Babri Mosque controversy which culminated in the deaths of perhaps 2000 people as well as the destruction of an historical site, the mosque itself. While many factors are likely to have contributed, the SSCP controversy, in which thousands of concerned Hindus mobilized in protests, resulted in little if no injury or damage to property. This was, perhaps, due in part to the nature of the public discourse.La naturaleza del discurso en la cultura pública ha experimentado cambios notables en el transcurso de unas décadas. El análisis del proyecto Sethusamudram Shipping Canal Project (SSCP para la creación de una línea de navegación comercial entre la India y Sri Lanka muestra el efecto de este cambio en el que Internet ha sido decisivo debido a la mayor afluencia de noticias y a su rápida difusión respecto de los medios tradicionales de comunicación y de creación de opinión pública. Solo dos décadas atrás, cuando Internet iniciaba su andadura, muchos de los partidos políticos y agencias gubernamentales involucrados en el SSCP se vieron implicados en el polémico asunto de la Mezquita de Babri que culminó con la muerte de casi 2.000 personas así como con la destrucción del propio monumento.

  6. Understanding the physical and chemical nature of the warfarin drug binding site in human serum albumin: experimental and theoretical studies.

    Abou-Zied, Osama K

    2015-01-01

    Human serum albumin (HSA) is one of the major carrier proteins in the body and constitutes approximately half of the protein found in blood plasma. It plays an important role in lipid metabolism, and its ability to reversibly bind a large variety of pharmaceutical compounds makes it a crucial determinant of drug pharmacokinetics and pharmacodynamics. This review deals with one of the protein's major binding sites "Sudlow I" which includes a binding pocket for the drug warfarin (WAR). The binding nature of this important site can be characterized by measuring the spectroscopic changes when a ligand is bound. Using several drugs, including WAR, and other drug-like molecules as ligands, the results emphasize the nature of Sudlow I as a flexible binding site, capable of binding a variety of ligands by adapting its binding pockets. The high affinity of the WAR pocket for binding versatile molecular structures stems from the flexibility of the amino acids forming the pocket. The binding site is shown to have an ionization ability which is important to consider when using drugs that are known to bind in Sudlow I. Several studies point to the important role of water molecules trapped inside the binding site in molecular recognition and ligand binding. Water inside the protein's cavity is crucial in maintaining the balance between the hydrophobic and hydrophilic nature of the binding site. Upon the unfolding and refolding of HSA, more water molecules are trapped inside the binding site which cause some swelling that prevents a full recovery from the denatured state. Better understanding of the mechanism of binding in macromolecules such as HSA and other proteins can be achieved by combining experimental and theoretical studies which produce significant synergies in studying complex biochemical phenomena.

    Refers to co-location concept, Kabil site, where located at the southeast end of low hills in Batam Island, will be sited as an integrated industrial waste management center including landfill. So that, it is necessary an evaluation of the landfill site candidate for NORM and hazardous waste. The evaluation includes geological and non-geological aspects, to determine the suitability or capability in supporting the function as landfill facility. The site candidate was evaluated by serial sreps as follows: 1) criteria formulation; 2) selecting the parameter for evaluation; 3) Positive screening or evaluation of the land having potentiality for landfill site by descriptive method: and 4) determine the land suitability or capability for landfill site. The evaluation of geological and non- geological aspects include topography, litology, seismicity, groundwater and surface water, climate, hydro-oceanography, flora and fauna, spatial pattern and transportation system. The most of the parameters evaluated show the fulfilling to the site criteria, and can be mentioned that the land is suitable for landfill site. Some parameters are not so suitable for that purpose, especially on permeability and homogeneity of the rocks/soils, distance to surface water body, depth of groundwater, the flow rate of groundwater, precipitation, and humidity of the air. The lack of suitability showed by some parameters can be compensated by improving the appropriate engineered barrier in order to fulfill the landfill performance in providing the supporting capacity, long live stability and waste containment.

    2017-01-01

    Full Text Available Religious and traditional beliefs, cultural mores, and practices play a crucial role in the conservation of environment and biodiversity. The present paper describes a case study of two sacred groves in Western Himalaya. Sacred groves (SGs are patches of land that are communally protected with religious zeal. A preliminary survey was conducted in these SGs to study their role in biodiversity conservation. The data collected included the general information regarding the SGs and the associated deity, nearest human habitation, access to them, and their floral and faunal diversity. Ethnomedicinal property of plants was collected from the indigenous communities. Many taboos are associated with both the SGs, which help in managing resources well through ritual representation. Different festivals are organized, where the local communities reaffirm their commitment to the forest and the deity. Sacred groves, in general, are a valuable tool of biodiversity conservation. But people’s changing attitudes, erosion of traditional beliefs, and human impact have caused degradation of sacred groves over the years. Their conservation would not be possible without the active participation of the local people. By improving their living standards and by giving benefits of conservation to them, long-term conservation goals in these SGs can be achieved.

    The British Geological Survey has been conducting a co-ordinated research programme at the natural analogue site of Needle's Eye at Southwick on the Solway coast in SW Scotland. This study of a naturally radioactive geochemical system has been carried out with the aim of improving our confidence in using predictive models of radionuclide migration in the geosphere. This report describes results of integrated mineralogical techniques which have been applied to the study of both the 'source-term' and sites of secondary accumulation of uranium. Pitchblende in a polymetallic-carbonate breccia vein exposed in ancient sea-cliffs is the main source of labile uranium although other uranium-bearing minerals present in the granodiorite and hornfelsed siltstone host-rocks present probable ancillary leachable sites. In keeping with the complex chemistry of the primary sulphide-rich mineralization, a large variety of secondary U minerals has been recorded among which arsenates and hydrous silicates appear to predominate. Uranium transported in groundwaters draining the cliffs has accumulated in organic-rich estuarine/intertidal mudflat sediments of Quaternary age. Charged particle track registration techniques have demonstrated convincingly the effectiveness of humidified organic matter in retarding uranium transport and, coupled with scanning electron microscopy, have indicated an important role of living plants and bacteria in uranium uptake and concentration.

    This pilot study presents a methodology for modeling project characteristics using a development model of a stream obstructing dam. The model is applied to all individual stream reaches in hydrologic region 17, which encompasses nearly all of Idaho, Oregon, and Washington. Project site characteristics produced by the modeling technique include: capacity potential, principal dam dimensions, number of required auxiliary dams, total extent of the constructed impoundment boundary, and the surface area of the resulting reservoir. Aggregated capacity potential values for the region are presented in capacity categories including total, that at existing dams, within federal and environmentally sensitive exclusion zones, and the balance which is consider available for greenfield development within the limits of the study. Distributions of site characteristics for small hydropower sites are presented and discussed. These sites are screened to identify candidate small hydropower sites and distributions of the site characteristics of this site population are presented and discussed. Recommendations are made for upgrading the methodology and extensions to make the results more accessible and available on a larger scale.

    Korea Radioactive-waste Management Corporation (KRMC) established in 2009 has started a new project to collect information on long-term stability of deep geological environments on the Korean Peninsula. The information has been built up in the integrated natural barrier database system available on web (www.deepgeodisposal.kr). The database system also includes socially and economically important information, such as land use, mining area, natural conservation area, population density, and industrial complex, because some of this information is used as exclusionary criteria during the site selection process for a deep geological repository for safe and secure containment and isolation of spent nuclear fuel and other long-lived radioactive waste in Korea. Although the official site selection process has not been started yet in Korea, current integrated natural barrier database system and socio-economic database is believed that the database system will be effectively utilized to narrow down the number of sites where future investigation is most promising in the site selection process for a deep geological repository and to enhance public acceptance by providing readily-available relevant scientific information on deep geological environments in Korea.

    Environmental managers require information on whether human-made hibernacula are used by rare snakes before constructing large numbers of them as mitigation measures. Fidelity of northern pine snakes (Pituophis m. melanoleucus) was examined in a 6-year study in the New Jersey Pine Barrens to determine whether they used natural and artificial hibernacula equally. Pine snakes used both artificial (human-made) and natural (snake-adapted) hibernacula. Most natural hibernacula were in abandoned burrows of large mammals. Occupancy rates were similar between natural and artificial hibernacula. Only 6 of 27 radio-tracked snakes did not shift hibernacula between years, whereas 78% shifted sites at least once, and fidelity from one year to the next was 42%. For snakes that switched hibernacula (n = 21), one switched among artificial hibernacula, 14 (65%) switched among natural hibernacula, and 6 (29%) switched from artificial to natural hibernacula. Data indicate that most pine snakes switch among hibernacula, mainly selecting natural hibernacula, suggesting that artificial dens are used, but protecting natural hibernacula should be a higher conservation priority.

    Investigation of radionuclides (232Th and 238U) and trace elements (Cr, As and Pb) in soil from two legacy NORM (former mining sites) and one undisturbed naturally 232Th-rich site was conducted as a part of the ongoing environmental impact assessment in the Fen Complex area (Norway). The major objectives were to determine the radionuclide and trace element distribution and mobility in soils as well as to analyze possible differences between legacy NORM and surrounding undisturbed naturally 232Th-rich soils. Inhomogeneous soil distribution of radionuclides and trace elements was observed for each of the investigated sites. The concentration of 232Th was high (up to 1685 mg kg(-1), i.e., ∼7000 Bq kg(-1)) and exceeded the screening value for the radioactive waste material in Norway (1 Bq g(-1)). Based on the sequential extraction results, the majority of 232Th and trace elements were rather inert, irreversibly bound to soil. Uranium was found to be potentially more mobile, as it was associated with pH-sensitive soil phases, redox-sensitive amorphous soil phases and soil organic compounds. Comparison of the sequential extraction datasets from the three investigated sites revealed increased mobility of all analyzed elements at the legacy NORM sites in comparison with the undisturbed 232Th-rich site. Similarly, the distribution coefficients Kd (232Th) and Kd (238U) suggested elevated dissolution, mobility and transportation at the legacy NORM sites, especially at the decommissioned Nb-mining site (346 and 100 L kg(-1) for 232Th and 238U, respectively), while the higher sorption of radionuclides was demonstrated at the undisturbed 232Th-rich site (10,672 and 506 L kg(-1) for 232Th and 238U, respectively). In general, although the concentration ranges of radionuclides and trace elements were similarly wide both at the legacy NORM and at the undisturbed 232Th-rich sites, the results of soil sequential extractions together with Kd values supported the expected differences

    Condensate liquids are present in soil and groundwater at two gas production sites in the Denver-Julesburg Basin operated by Amoco. These sites have been closely monitored since July 1993 to determine whether intrinsic aerobic or anaerobic bioremediation of hydrocarbons occurs at a sufficient rate and to an adequate endpoint to support a no-intervention decision. Groundwater monitoring and analysis of soil cores strongly suggest that intrinsic bioremediation is occurring at these sites by multiple pathways, including aerobic oxidation, Fe(III) reduction, and sulfate reduction

    The Tibetan sacred mountains (TSMs) cover a large area and may represent a landscape-scale conservation opportunity. We compared the conservation value of forests in these mountains with the conservation value of government-established nature reserves and unmanaged open-access areas in Danba County, southwestern China. We used Landsat satellite images to map forest cover and to estimate forest loss in 1974-1989, 1989-1999, and 1999-2013. The TSMs (n = 41) and nature reserves (n = 4) accounted for 21.6% and 29.7% of the county's land area, respectively. Remaining land was open-access areas (i.e., areas without any restrictions on resource use) (56.2%) and farmlands (2.2%). Within the elevation range suitable for forests, forest cover did not differ significantly between nature reserves (58.8%) and open-access areas (58.4%), but was significantly higher in TSMs (65.5%) after controlling for environmental factors such as aspect, slope, and elevation. The TSMs of great cultural importance had higher forest cover, but patrols by monastery staff were not necessarily associated with increased forest cover. The annual deforestation rate in nonsacred areas almost tripled in 1989-1999 (111.4 ha/year) relative to 1974-1989 (40.4 ha/year), whereas the rate in TSMs decreased in the later period (19.7 ha/year vs. 17.2 ha/year). The reduced forest loss in TSMs in 1989-1999 was possibly due to the renaissance of TSM worship and strengthened management by the local Buddhist community since late 1980s. The annual deforestation rate in Danba decreased dramatically to 4.4 ha/year in 1999-2013, which coincided with the implementation of a national ban on logging in 1998. As the only form of protected area across the Tibetan region during much of its history, TSMs have positively contributed to conserving forest at a landscape scale. Conservation of TSM forests largely relied on the strength of local religious institutions. Integrating community-based conservation of TSMs within the

    Natural gas has become a leading source of alternative energy with the advent of techniques to economically extract gas reserves from deep shale formations. Here, we present an assessment of private well water quality in aquifers overlying the Barnett Shale formation of North Texas. We evaluated samples from 100 private drinking water wells using analytical chemistry techniques. Analyses revealed that arsenic, selenium, strontium and total dissolved solids (TDS) exceeded the Environmental Protection Agency's Drinking Water Maximum Contaminant Limit (MCL) in some samples from private water wells located within 3 km of active natural gas wells. Lower levels of arsenic, selenium, strontium, and barium were detected at reference sites outside the Barnett Shale region as well as sites within the Barnett Shale region located more than 3 km from active natural gas wells. Methanol and ethanol were also detected in 29% of samples. Samples exceeding MCL levels were randomly distributed within areas of active natural gas extraction, and the spatial patterns in our data suggest that elevated constituent levels could be due to a variety of factors including mobilization of natural constituents, hydrogeochemical changes from lowering of the water table, or industrial accidents such as faulty gas well casings.

    More than one hundred samples of European beers have been investigated by the new SNIF-NMR method which is based on 2H NMR at the natural abundance level and enables site-specific natural isotope fractionation factors in ethanol to be determined. The relative (R) and absolute (D/H)sub(i) parameters are shown to be characteristic of the country where the beers are brewed and the observed variations are explained in terms of cereal composition, water resource, and manufacturing processing (fermentation, yeast, temperature cycle). These new parameters find analytical and mechanistic applications in the identification of a beer and in the investigation of a fermentation process. (author)

    Natural radioactivity, a basic component of the environment, is determined by the presence in soil, atmosphere, water, vegetation, live elements and humans of radioactive matter of terrestrial origin, naturally existing from the very beginning. To all these, extra-terrestrial cosmic radiation must be added. Human exposure to terrestrial radiation is due to radionuclides present in the earth crust or to those transferred from atmosphere or hydrosphere. An abundance of radionuclides present in the crust are radioactive. Their lifetime is shorter or equal to the estimated age of the earth crust and, consequently, they are presumed to represent a primordial inventory. Uranium and thorium in natural state decay in three different series, the first ones being the radionuclides 2 38U , 2 35U and 2 32T h. The population exposure to radiation must take into account both natural and artificial radiation

    Tar oil is a complex mixture of mainly aromatic hydrocarbons. It is found in the subsurface of manufactured gas plants (MGP), coking plants or wood preserving facilities. The transportation into the soil and groundwater stands for a severe contamination. This is due to the physico-chemical properties of the DNAPL (dense non aqueous phase liquid) and its mobility in the soil and aquifer system. Additionally most of the contaminants show a low biological degradability and solubility under in situ conditions. Therefore it is known as a long term source of contamination. Nevertheless, natural attenuation (NA) processes are detectable at tar oil contaminated sites. In the thematic network two of the German funding priority KORA (http://www.natural-attenuation.de) these processes are matter of investigation. Four typical contaminated sites were chosen to evaluate under which circumstances monitored natural attenuation (MNA) is applicable. Furthermore enhanced natural attenuation questions are examined. The design of monitoring networks at tar oil contaminated sites plays a significant role in gaining field evidence for natural attenuation as well as documenting the efficiency of the attenuation processes and evaluating the matching of performance goals. Well designed monitoring networks include the placement of monitoring wells in 3D so that 3D flow path, mass balances and an estimation of mass flux can be monitored. As an example the history of the monitoring network of a wood preserving facility is shown. Starting from a risk assessment network to a network for MNA is presented. In this case for example especially the determination of the groundwater flow direction in time and space is connected to the number of observation wells and their location. Moreover in the beginning the observation wells were located according to the assumed centerline of the plume. Because of the variability of the groundwater flow direction and the need to determine mass flux a control plane

    The long-term durability of low alkali cements is of interest where they are under consideration as repository tunnel and exploration borehole seals and plugs. It is essential to have an appropriate understanding of their longevity to inform decisions on their potential use in a repository environment. Archaelogical analogues of low alkali cement have been studied for some time. Thomassin and Rassineux (1992), for example, reviewed some of the literature on Gallo-Roman cement-based materials and noted that one of the most impressive examples is the 1700 year old Roman mortar used in Hadrian's Wall (UK) which still contains substantial amounts of CSH (calcium silicate hydrate) compounds. These mortars were studied specifically with the behaviour of an ILW repository in mind (Jull and Lees 1990). However, plugs and seals will generally be required to be durable for longer than the few thousand years which can be accessed via archaeological analogues, so it is essential to turn to natural systems for evidence of longer term durability. To date, there have been no reported studies on natural low alkali cements. In principle, however, such cements should exist and the Bituminous Marl Formation, which hosts the natural OPC cements in Jordan (Pitty and Alexander, 2011), is a likely source. This Formation constitutes a widespread terrain which stretches from Syria in the north, through Israel and Jordan to Saudi Arabia in the south. The natural cement was formed by the combustion of organic rich limestones, a process which continues today. In Syria and northern Jordan, for example, the Formation is punctured by Late Oligocene to Quaternary volcanics so sites which include pozzolanic ash mixed with the Bituminous Marl exist and, on combustion, should produce natural low alkali cements. A site in northern Jordan is currently under investigation for evidence of long-term fresh groundwater/low alkali cement interaction and the preliminary results of the study will be

    Single-incision laparoscopic surgery (SILS) is gaining popularity for a wide variety of surgical operations and capitalizes on the benefits of traditional laparoscopic surgery without incurring multiple incision sites. Traditionally, SILS is performed by a midline periumbilical approach. However, such a minimally invasive approach may be utilized in patients who already have an abdominal incision. Our series retrospectively reviews 7 cases in which we utilized the fascial defect at the time of after ostomy reversal as our SILS incision site. In turn, we performed a variety of concurrent intra-abdominal procedures with excellent technical success and outcomes. Our study is the largest single-institution case series of this novel approach and suggests that utilizing an existing ostomy-site abdominal incision is a safe and effective location for SILS port placement and should be considered in patients undergoing concurrent procedures.

    1988-01-01

    Gamma-irradiation of a laboratory strain of the Hawaiian species of Drosophila heteroneura yielded 310 breaks in the five major acrocentric polytene chromosomes. Their map positions conform to the Poisson distribution, unlike most of the 436 natural breaks mapped in 105 closely related species endemic to Hawaii. Genome element E is longer and has more induced breaks than the others. Both in Hawaiian and related species groups, this element shows increased polymorphism and fixation of naturally occurring inversions. The X chromosome (element A) also accumulates many natural breaks; the majority of the resulting aberrations become fixed rather than remain as polymorphisms. Although size may play a small role in initial break distribution, the major effects relative to the establishment of a rearrangement in natural populations are ascribed to the interaction of selection and drift. Nonconformance of the natural breaks to the Poisson distribution appears to be due to the tendency for breaks to accumulate both in the proximal euchromatic portion of each arm and in heterochromatic regions that are not replicated in the polytene chromosomes

    A major question in evolutionary biology is how natural selection has shaped patterns of genetic variation across the human genome. Previous work has documented a reduction in genetic diversity in regions of the genome with low recombination rates. However, it is unclear whether other summaries...... these questions by analyzing three different genome-wide resequencing datasets from European individuals. We document several significant correlations between different genomic features. In particular, we find that average minor allele frequency and diversity are reduced in regions of low recombination...... and that human diversity, human-chimp divergence, and average minor allele frequency are reduced near genes. Population genetic simulations show that either positive natural selection acting on favorable mutations or negative natural selection acting against deleterious mutations can explain these correlations...

    Natural analogs provide a line of evidence that supports the understanding of how natural and engineered processes would occur over long time frames and large spatial scales at a potential nuclear waste repository at Yucca Mountain, Nevada. Studies of U-series disequilibria within and around uranium deposits can provide valuable information on the timing of actinide mobility and hence the stability of a potential repository over geologic time scales. The Nopal I uranium deposit at Pena Blanca, Mexico, is situated in unsaturated tuff that is similar in composition to the Topopah Spring Tuff of Yucca Mountain and closely matches other evaluation criteria for suitable natural analogs. By modeling the observed radioactive isotope disequilibria at Nopal I, we can estimate the rates of sorption-desorption and dissolution-precipitation of the radionuclides over time. Such information is vital to the testing or validation of performance assessment models for geologic nuclear waste disposal.

    Concentration distributions of natural decay chains 4n+2 and 4n+3 in crystalline rock intersected by a natural fracture were measured. Calcite coating on the same fracture surface was dated. Material properties of the rock matrix, and nuclide concentrations in groundwater were measured. The interpretation of the concentration distributions is based on the classical matrix diffusion concept. Although support was obtained, this calibration exercise does not yet validate the model. Besides initial and boundary conditions, matrix properties are uncertain due to the small amount of rock material. Experimental sorption data was not available, but its importance and the need for systematic studies was demonstrated. (orig.) (10 refs., 5 figs., 5 tabs.)

    Many ecosystem services provided by forests are important for the livelihoods of indigenous people. Sacred forests are used for traditional practices by the ethnic minorities in northern Thailand and they protect these forests that are important for their culture and daily life. Swidden fallow fields are a dominant feature of the agricultural farming landscapes in the region. In this study we evaluate and compare the importance of swidden fallow fields and sacred forests as providers of medicinal plants among the Karen and Lawa ethnic minorities in northern Thailand. We made plant inventories in swidden fallow fields of three different ages (1-2, 3-4, 5-6 years old) and in sacred forests around two villages using a replicated stratified design of vegetation plots. Subsequently we interviewed the villagers, using semi-structured questionnaires, to assess the medicinal use of the species encountered in the vegetation survey. We registered a total of 365 species in 244 genera and 82 families. Of these 72(19%) species in 60(24%) genera and 32(39%) families had medicinal uses. Although the sacred forest overall housed more species than the swidden fallow fields, about equal numbers of medicinal plants were derived from the forest and the fallows. This in turn means that a higher proportion (48% and 34%) of the species in the relatively species poor fallows were used for medicinal purposes than the proportion of medicinal plants from the sacred forest which accounted for 17-22%. Of the 32 medicinal plant families Euphorbiaceae and Lauraceae had most used species in the Karen and Lawa villages respectively. Sacred forest are important for providing medicinal plant species to the Karen and Lawa communities in northern Thailand, but the swidden fallows around the villages are equally important in terms of absolute numbers of medicinal plant species, and more important if counted as proportion of the total number of species in a habitat. This points to the importance of

    With the recent expansion of U.S. oil and gas (O&G) production, many studies have focused on the quantification of fugitive methane emissions. However, only a few studies have explored the emissions of volatile organic compounds (VOCs) from O&G production sites that affect human health in adjacent communities, both directly through exposure to toxic chemical compounds and indirectly via formation of ground-level ozone. In this study, we seek to quantify emissions of VOCs from O&G production sites and petrochemical facilities using a mobile sensing approach, with both high-end analyzers and relatively low-cost sensors. A probabilistic source characterization approach is used to estimate emission rates of VOCs, directly taking into account quantitative measure of sensor accuracy. This work will provide data with proper spatiotemporal resolution and coverage, so as to improve the understanding of VOCs emission from O&G production sites, VOCs-exposure of local communities, and explore the feasibility of low-cost sensors for VOCs monitoring. The project will provide an important foundational step to enable large scale studies.

    The location of the microhabitats where immature phlebotomine sand flies of the genus Lutzomyia develop is one of the least-known aspects of this group of medically important insects. For this reason strategies of source reduction approach for their control have not been possible in contrast to other insect vectors (such as mosquitoes), because their juvenile stages in terrestrial microhabitats is difficult to detect. Direct examination of soil samples, incubation of substrates and the use of emergence traps were the methods used to identify juvenile stages in 160 soil samples from urban and forest habitats within the foci of Leishmania transmission in Colombia. Immatures collected were identified subsequent from the rearing and emergence of adults using taxonomic keys or the analysis of the mitochondrial marker cytochrome oxidase I. Plant species associated with the natural breeding sites were identified and physicochemical properties of the soils were analyzed. A total of 38 (23.7%) sampling sites were identified as breeding sites, 142 phlebotomine sand flies were identified, belonging to 13 species of the genus Lutzomyia and two of Brumptomyia. The greatest numbers of immature were found within the tabular roots (51 immature sand flies from eight positive sites) and bases of trees (35 immature sand flies from 11 sites). The characterization and presence of the tree species (mainly Ceiba pentadra, Anacardium excelsum, Pseudosamanea guachapale) and the physicochemical properties (relative humidity and carbon/nitrogen ratio) of the soils associated with these breeding sites are significant factors in explaining the diversity and abundance of phlebotomine sand flies. Immature phlebotomine sand flies of the genus Lutzomyia in Colombia can be found in a wide variety of breeding sites rich in organic matter, high relative humidity and are associated with a typical vegetation of each locality. These results provide new perspectives for the study of the ecology of the

    Movement of contaminants in groundwater at the Hanford Site is heavily dependent on recharge to the unconfined aquifer. As the effects of past artificial discharges dissipate, the water table is expected to return to more natural conditions, and natural recharge will become the driving force when evaluating future groundwater flow conditions and related contaminant transport. Previous work on the relationship of natural recharge to groundwater movement at the Hanford Site has focused on direct recharge from infiltrating rainfall and snowmelt within the area represented by the Sitewide Groundwater Model (SGM) domain. However, part of the groundwater recharge at Hanford is provided by flow from Greater Cold Creek watershed (GCC), a large drainage area on the western boundary of the Hanford Site that includes Cold Creek Valley, Dry Creek Valley, and the Hanford side of Rattlesnake Mountain. This study was undertaken to estimate the recharge from GCC, which is believed to enter the unconfined aquifer as both infiltrating streamflow and shallow subsurface flow. To estimate recharge, the Distributed Hydrology-Soil-Vegetation Model (DHSVM) was used to simulate a detailed water balance of GCC from 1956 to 2001 at a spatial resolution of 200~m and a temporal resolution of one hour. For estimating natural recharge to Hanford from watersheds along its western and southwestern boundaries, the most important aspects that need to be considered are 1)~distribution and relative magnitude of precipitation and evapotranspiration over the watershed, 2)~streamflow generation at upper elevations and infiltration at lower elevations during rare runoff events, and 3)~permeability of the basalt bedrock surface underlying the soil mantle.

    The present study was conducted in environs of the sacred grove of Garhwal Himalaya, India, with a view to assess the impacts of sacred groves and forests on the quality and quantity of water and also to assess the effect of seasonality on perennial stream quality. Water samples were collected from three randomly selected stream spots of both the sacred grove dominated by deodar (Cedrus deodara) and the non-sacred patch dominated by oak (Quercus leucotrichophora). Water samples from both patches were within the World Health Organization (WHO) standard limits. Based on an already established water quality index, water quality of both patches was safe for domestic and irrigation purposes but needs treatment for drinking purposes. Results of the present study also showed a very prominent impact of forest type as well as management condition on water quality and quantity. The water discharge from an oak forest shows more consistency than the discharge from a deodar forest. Due to the presence of the sacred grove, the area has become the source of good quality water supply during lean season for the surrounding villages. Water quality and quantity differed along with the change in season. The sacred grove and the existing forest leave a great impression on local dwellers, as due to its presence, local dwellers never run out of water supply during the dry season. As a result, the villagers sincerely want to protect the area for the sake of their own well-being.

  9. Summary of Natural Resources that Potentially Influence Human Intrusion at the Area 5 Radioactive Waste Management Site, Nevada Test Site, Nye County, Nevada

    In 1993, Raytheon Services Nevada completed a review of natural resource literature and other sources to identify potentially exploitable resources and potential future land uses near the Area 5 Radioactive Waste Management Site (RWMS) of the Nevada Test Site (NTS), Nye County, Nevada, that could lead to future inadvertent human intrusion and subsequent release of radionuclides to the accessible environment. National Security Technologies, LLC, revised the original limited-distribution document to conform to current editorial standards and U.S. Department of Energy requirements for public release. The researchers examined the potential for future development of sand, gravel, mineral, petroleum, water resources, and rural land uses, such as agriculture, grazing, and hunting. The study was part of the performance assessment for Greater Confinement Disposal boreholes. Sand and gravel are not considered exploitable site resources because the materials are common throughout the area and the quality at the Area 5 RWMS is not ideal for typical commercial uses. Site information also indicates a very low mineral potential for the area. None of the 23 mining districts in southern Nye County report occurrences of economic mineral deposits in unconsolidated alluvium. The potential for oil and natural gas is low for southern Nye County. No occurrences of coal, tar sand, or oil shale on the NTS are reported in available literature. Several potential future uses of water were considered. Agricultural irrigation is impractical due to poor soils and existing water supply regulations. Use of water for geothermal energy development is unlikely because temperatures are too low for typical commercial applications using current technology. Human consumption of water has the most potential for cause of intrusion. The economics of future water needs may create a demand for the development of deep carbonate aquifers in the region. However, the Area 5 RWMS is not an optimal location for

  11. Natural selection affects multiple aspects of genetic variation at putatively neutral sites across the human genome.

    A major question in evolutionary biology is how natural selection has shaped patterns of genetic variation across the human genome. Previous work has documented a reduction in genetic diversity in regions of the genome with low recombination rates. However, it is unclear whether other summaries of genetic variation, like allele frequencies, are also correlated with recombination rate and whether these correlations can be explained solely by negative selection against deleterious mutations or whether positive selection acting on favorable alleles is also required. Here we attempt to address these questions by analyzing three different genome-wide resequencing datasets from European individuals. We document several significant correlations between different genomic features. In particular, we find that average minor allele frequency and diversity are reduced in regions of low recombination and that human diversity, human-chimp divergence, and average minor allele frequency are reduced near genes. Population genetic simulations show that either positive natural selection acting on favorable mutations or negative natural selection acting against deleterious mutations can explain these correlations. However, models with strong positive selection on nonsynonymous mutations and little negative selection predict a stronger negative correlation between neutral diversity and nonsynonymous divergence than observed in the actual data, supporting the importance of negative, rather than positive, selection throughout the genome. Further, we show that the widespread presence of weakly deleterious alleles, rather than a small number of strongly positively selected mutations, is responsible for the correlation between neutral genetic diversity and recombination rate. This work suggests that natural selection has affected multiple aspects of linked neutral variation throughout the human genome and that positive selection is not required to explain these observations.

    In this study, agriculture soil in Taiwan has been sampled and analyzed to determine the background level of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/DF) in the agricultural and nature preserve areas. Another objective is to investigate relationship between soil characteristics and air deposition in Taiwan. The results indicate that in nature preserve areas the topsoil shows an extraordinary profile of PCDD/DF compared to that in the air deposition. The PCDD/DF levels of the low-contaminated agricultural soils are compatible with those of the nature preserves soils. However, in the highly-contaminated agricultural soils, there is an abrupt jump in their concentrations, 10-100 times higher. The overall I-TEQ values of the background topsoils range from 0.101 to 15.2 ng I-TEQ/kg. Near industrial/urban areas in Taiwan the PCDD/DF are slightly higher compared to those in the low concentration group. Typically, the PCDD/DF background values found in this survey fall in the 90% confidence interval and can thus, be deemed the background levels in Taiwan. Ninety-five percent of these data are below the European and American soil standard of 10 ng I-TEQ/kg d.w. The PCDD/DF profile with one neighborhood soil sample was shown no significant difference.

    Full Text Available The image of the Sacred scarab, like any other fact of culture, should be considered only in the context of certain circumstances, which involve the approach choice: viewing as either a sign or a symbol. In those cases where the scarab image stands as a symbol, while interpreting this one it should be taken into account the cultural context, which, as relevant studies show, can never be reduced to a simple interpretation scheme “Scarab — Dorbeetle — Sun symbol”. In that connection suggested is a hypothesis, according to which the image of the Sacred scarab as a symbol is divided into two, at least, concepts: a “Sunny Beetle”, to mean the beetle species Cetonia aurata (or any other similar, and a “Beetle-Demiurge”, to mean the dorbeetle.

  15. Sacred Torrents in Modernity: German Jewish Philosophers and the Legacy of Secularization

    Directory of Open Access Journals (Sweden)

    Roemer Nils

    2016-12-01

    Full Text Available This article investigates the ongoing interaction between the Jewish sacred past and its modern interpreters. Jewish thinkers from the eighteenth century reclaimed these ideals instead of dismissing them. Sacred traditions and modern secular thought existed in their mutual constitutive interdependence and not in opposition. When the optimism in historical progress and faith in reason unraveled in the fin de siècle, it engendered a new critical response by Jewish historians and philosophers of the twentieth century. These critical voices emerged within the fault lines of nineteenth and early twentieth century Jewish anti-historicist responses. What separated twentieth-century Jewish thinkers such as Martin Buber, Franz Rosenzweig, and Gershom Scholem from their nineteenth-century forerunners was not their embrace of religion but their critical stance toward reason and their crumbling faith in historical progress.

  16. Catalytic Pyrolysis of Chilean Oak: Influence of Brønsted Acid Sites of Chilean Natural Zeolite

    Directory of Open Access Journals (Sweden)

    Serguei Alejandro Martín

    2017-11-01

    Full Text Available This paper proposes the Chilean natural zeolite as catalyst on bio-oil upgrade processes. The aim of this study was to analyze chemical composition of bio-oil samples obtained from catalytic pyrolysis of Chilean native oak in order to increase bio-oil stability during storage. In order to identify chemical compounds before and after storage, biomass pyrolysis was carried out in a fixed bed reactor at 623 K and bio-oil samples were characterized by gas chromatography/mass spectrophotometry (GC/MS. A bio-oil fractionation method was successfully applied here. Results indicate that bio-oil viscosity decreases due to active sites on the zeolite framework. Active acids sites were associated with an increment of alcohols, aldehydes, and hydrocarbon content during storage. Higher composition on aldehydes and alcohols after storage could be attributed to the occurrence of carbonyl reduction reactions that promotes them. These reactions are influenced by zeolite surface characteristics and could be achieved via the direct contribution of Brønsted acid sites to Chilean natural zeolite.

    Advisability of using risks as indicators for estimating radiation impacts on environmental objects and humans has been jusified. Results are presented from identification of dose burdens distribution to various cohorts of the population living within the Semipalatinsk Test Site (STS) and consuming contaminated farm products. Parameters of dose burden distributions are estimated for areas of livestock grazing and the most contaminated sectors within these areas. Dose distributions to meadow plants for the above areas have been found. Regulatory radiation risks for the STS population and meadow ecosystem components have been calculated. Based on the parameters estimated, levels of radiation exposure of the population and herbaceous plants have been compared.

    Sacred lotus is a basal eudicot with agricultural, medicinal, cultural and religious importance. It was domesticated in Asia about 7,000 years ago, and cultivated for its rhizomes and seeds as a food crop. It is particularly noted for its 1,300-year seed longevity and exceptional water repellency, known as the lotus effect. The latter property is due to the nanoscopic closely packed protuberances of its self-cleaning leaf surface, which have been adapted for the manufacture of a self-cleaning industrial paint, Lotusan. The genome of the China Antique variety of the sacred lotus was sequenced with Illumina and 454 technologies, at respective depths of 101× and 5.2×. The final assembly has a contig N50 of 38.8 kbp and a scaffold N50 of 3.4 Mbp, and covers 86.5% of the estimated 929 Mbp total genome size. The genome notably lacks the paleo-triplication observed in other eudicots, but reveals a lineage-specific duplication. The genome has evidence of slow evolution, with a 30% slower nucleotide mutation rate than observed in grape. Comparisons of the available sequenced genomes suggest a minimum gene set for vascular plants of 4,223 genes. Strikingly, the sacred lotus has 16 COG2132 multi-copper oxidase family proteins with root-specific expression; these are involved in root meristem phosphate starvation, reflecting adaptation to limited nutrient availability in an aquatic environment. The slow nucleotide substitution rate makes the sacred lotus a better resource than the current standard, grape, for reconstructing the pan-eudicot genome, and should therefore accelerate comparative analysis between eudicots and monocots.

    The human genome, and hence the human brain at birth, may not have changed greatly over the past 60000 years. Yet many of the major behavioural changes that we associate with most human societies are very much more recent, some appearing with the sedentary revolution of some 10000 years ago. Among these are activities implying the emergence of powerful concepts of value and of the sacred. What then are the neuronal mechanisms that may underlie these consistent, significant (and emergent) patterns of behaviour?

    2010-01-01

    We explored the semi-natural forests in south western Anatolia along a gradient between Mediterranean and continental climates to determine the site requirements of Juniperus excelsa in Turkey. We hypothesized that environmental variables and indicator species can be used to predict differences in occurrence and cover of J. excelsa and can therefore support decision making in reforestation management planning. Plant species composition and environmental variables were assessed in 153 plots. Association between J. excelsa and other plant species and environmental variables were analyzed using Fisher exact probability tests and stepwise discriminant analysis. High altitude (> 1000 m) as a proxy for an Oromediterranean climate, and high surface stoniness as a proxy for low competition by other tree species, are positive site properties for J. excelsa. The tree species avoids Eumediterranean and Supramediterranean plant communities. Twelve plant species, including the herbs Dianthus zonatus, Ajuga chamaepitys and Paronchia carica and the shrub Cotoneaster nummularia may be used as site indicators for J. excelsa restoration. Platanus orientalis, with similar site requirements but at present negatively associated to J. excelsa due to competitive effects, may be considered an additional indicator if stand conversion (harvesting and replacing P. orientalis) is part of the management plan.

    2001-06-01

    In Canada, very little data is available regarding the concentrations and chemical speciation of iodine in the environment proximal and distal to CANDU Nuclear Power Generating Stations (NPGS). In the immediate vicinity of CANDU reactors, the short-lived iodine isotope {sup 131}I (t{sub 1/2} = 8.04 d), which is produced from fission reactions, is generally below detection and yields little information about the environmental cycling of iodine. Conversely, the fission product {sup 129}I has a long half-life (t{sub 1/2} = 1.57x10{sup 7} y) and has had other anthropogenic inputs (weapons testing, nuclear fuel reprocessing) other than CANDU over the past 50 years. As a result, the concentrations of stable iodine ({sup 127}I) have been used as a proxy. In this study, a sampling system was developed and tested at AECL's Chalk River Laboratories (CRL) to collect and measure the particulate and gaseous inorganic and organic fractions of stable iodine ({sup 127}I) in air and associated organic and inorganic reservoirs. Air, vegetation and soil samples were collected at CRL, and at Canadian CANDU Nuclear Power Generating Stations (NPGS) at OPG's (Ontario Power Generation) Pickering (PNGS) and Darlington NPGS (DNGS) in Ontario, as well as at NB Power's Pt. Lepreau NPGS in New Brunswick. The concentrations of particulate and inorganic iodine in air at CRL were extremely low, and were often found to be below detection. The concentrations are believed to be at this level because the sediments in the CRL area are glacial fluvial and devoid of marine ionic species, and the local atmospheric conditions at the sampling site are very humid. Concentrations of a gaseous organic species were comparable to worldwide levels. The concentrations of particulate and inorganic iodine in air were also found to be low at PNGS and DNGS, which may be attributed to reservoir effects of the large freshwater lakes in southern Ontario, which might serve to dilute the atmospheric iodine

    Stephens, D.B.

    1985-01-01

    Milling operations throughout the world have created vast amounts of waste by-products, or tailings, which are often disposed on the land surface. The wastes may be disposed behind dams, on untreated ground, or on compacted clay or synthetic liners of impoundments and trenches. Often one of the principle concerns of environmental regulatory agencies is whether seepage from the waste pile could move through the vadose zone to the water table and possibly contaminate an aquifer. The seepage may be generated by the drainage of liquids initially deposited along with the tailings or by infiltrating meteoric water which leaches soluted from the tailings. The purpose of this article is to discuss some of the commonly held assumptions regarding storage of seepage wastes in the unsaturated zone. The significance of recent studies of water movement in dry climates which pertain to tailings site selection are presented

    Deltorphins are endogenous linear heptapeptides, isolated from skin extracts of frogs belonging to the genus Phyllomedusa, that have a higher affinity and selectivity for delta opioid binding sites than any other natural compound known. Two deltorphins with the sequence Tyr-Ala-Phe-Asp(or Glu)-Val-Val-Gly-NH2 have been isolated from skin extracts of Phyllomedusa bicolor. The alanine in position 2 is in the D configuration. These peptides, [D-Ala2]deltorphins I and II, show an even higher affi...

    Full Text Available Halyomorpha halys is an invasive species from Asia causing major economic losses in agricultural production in the mid-Atlantic region of the United States. Unlike other crop pests, H. halys is also well-known for nuisance problems in urban, suburban, and rural areas, as massive numbers of adults often invade human-made structures to overwinter inside protected environments. Research efforts have focused on populations in human-made structures while overwintering ecology of H. halys in natural landscapes is virtually unknown. We explored forested landscapes in the mid-Atlantic region to locate and characterize natural overwintering structures used by H. halys. We also evaluated the use of detector canines to locate overwintering H. halys to enhance the accuracy and efficiency of surveys. From these studies, we indentified shared characteristics of overwintering sites used by H. halys in natural landscapes. Overwintering H. halys were recovered from dry crevices in dead, standing trees with thick bark, particularly oak (Quercus spp. and locust (Robinia spp.; these characteristics were shared by 11.8% of all dead trees in surveyed landscapes. For trees with favorable characteristics, we sampled ∼20% of the total above-ground tree area and recovered 5.9 adults per tree from the trees with H. halys present. Two detector canines were successfully trained to recognize and detect the odor of adult H. halys yielding >84% accuracy in laboratory and semi-field trials. Detector canines also found overwintering H. halys under field conditions. In particular, overwintering H. halys were recovered only from dead trees that yielded positive indications from the canines and shared key tree characteristics established by human surveyors. The identified characteristics of natural overwintering sites of H. halys will serve as baseline information to establish crop economic risk levels posed by overwintering populations, and accordingly develop sustainable

    Oil and natural gas operations have continued to expand and move closer to densely populated areas, contributing to growing public concerns regarding exposure to hazardous air pollutants. During the Barnett Shale Coordinated Campaign in October, 2013, ground-based whole air samples collected downwind of oil and gas sites revealed enhancements in several potentially toxic volatile organic compounds (VOCs) when compared to background values. Molar emissions ratios relative to methane were determined for hexane, benzene, toluene, ethylbenzene, and xylene (BTEX compounds). Using methane leak rates measured from the Picarro mobile flux plane (MFP) system and a Barnett Shale regional methane emissions inventory, the rates of emission of these toxic gases were calculated. Benzene emissions ranged between 51 ± 4 and 60 ± 4 kg h -1 . Hexane, the most abundantly emitted pollutant, ranged from 642 ± 45 to 1070 ± 340 kg h -1 . While observed hydrocarbon enhancements fall below federal workplace standards, results may indicate a link between emissions from oil and natural gas operations and concerns about exposure to hazardous air pollutants. The larger public health risks associated with the production and distribution of natural gas are of particular importance and warrant further investigation, particularly as the use of natural gas increases in the United States and internationally.

    In 2010 a Composite Analysis (CA) of the U.S. Department of Energy’s (DOE’s) Savannah River Site (SRS) was completed. This investigation evaluated the dose impact of the anticipated SRS End State residual sources of radionuclides to offsite members of the public. Doses were assessed at the locations where SRS site streams discharge into the Savannah River at the perimeter of the SRS. Although the model developed to perform this computation indicated that the dose constraint of 0.3 mSv/yr (30 mrem/yr), associated with CA, was not approached at the Points of Assessment (POAs), a significant contribution to the total computed dose was derived from the radionuclides (primarily Cs-137) bound-up in the soil and sediment of the drainage corridors of several SRS streams. DOE’s Low Level Waste Federal Review Group (LFRG) reviewed the 2010 CA and identified several items to be addressed in the SRS Maintenance Program. One of the items recognized Cs-137 in the Lower Three Runs (LTR) Integrator Operable Unit (IOU), as a significant CA dose driver. The item made the recommendation that SRS update the estimated radionuclide inventory, including Cs-137, in the LTR IOU. That initial work has been completed and its radionuclide inventory refined. There are five additional streams at SRS and the next phase of the response to the LFRG concern was to obtain a more accurate inventory and distribution of radionuclides in three of those streams, Fourmile Branch (FMB), Pen Branch (PB) and Steel Creek (SC). Each of these streams is designated as an IOU, which are defined for the purpose of this investigation as the surface water bodies and associated wetlands, including the channel sediment, floodplain sed/soil, and related biota. If present, radionuclides associated with IOUs are adsorbed to the streambed sediment and soils of the shallow floodplains that lie immediately adjacent to stream channels. The scope of this effort included the evaluation of any previous sampling and

    We present techniques and a system for synthesizing views for video teleconferencing between small groups. In place of replicating one-to-one systems for each pair of users, we create a single unified display of the remote group. Instead of performing dense 3D scene computation, we use more cameras and trade-off storage and hardware for computation. While it is expensive to directly capture a scene from all possible viewpoints, we have observed that the participants viewpoints usually remain at a constant height (eye level) during video teleconferencing. Therefore, we can restrict the possible viewpoint to be within a virtual plane without sacrificing much of the realism, and in cloning so we significantly reduce the number of required cameras. Based on this observation, we have developed a technique that uses light-field style rendering to guarantee the quality of the synthesized views, using a linear array of cameras with a life-sized, projected display. Our full-duplex prototype system between Sandia National Laboratories, California and the University of North Carolina at Chapel Hill has been able to synthesize photo-realistic views at interactive rates, and has been used to video conference during regular meetings between the sites.

    Heavy metal accumulation in crops and soils from wastewater irrigation poses a significant threat to the human health. A study was carried out to investigate the removal potential of heavy metals (HM) by native plant species, namely Cannabis sativa L., Chenopodium album L., Datura stramonium L., Sonchus asper L., Amaranthus viridus L., Oenothera rosea (LHer), Xanthium stramonium L., Polygonum macalosa L., Nasturtium officinale L. and Conyza canadensis L. growing at the municipal wastewater site in Abbottabad city, Pakistan. The HM concentrations varied among plants depending on the species. Metal concentrations across species varied in the order iron (Fe) > zinc (Zn) > chromium (Cr) > nickel (Ni) > cadmium (Cd). Majority of the species accumulated more HM in roots than shoots. Among species, the concentrations (both in roots and shoots) were in the order C. sativa > C. album > X. stramonium > C. canadensis > A. viridus > N. officinale > P. macalosa > D. stramonium > S. asper > O. rosea. No species was identified as a hyperaccumulator. All species exhibited a translocation factor (TF) less than 1. Species like C. sativa, C. album and X. stramonium gave higher (> 1) biological concentration factor (BCF) and biological accumulation coefficient (BAC) especially for Fe, Cr and Cd than other species. Higher accumulation of heavy metals in these plant species signifies the general application of these species for phytostabilization and phytoextraction of HM from polluted soils.

  20. Linking Mn(II)-oxidizing bacteria to natural attenuation at a former U mining site

    Uranium mining near Ronneburg, Germany resulted in widespread environmental contamination with acid mine drainage (AMD) and high concentrations of heavy metals and radionuclides. Despite physical remediation of the area, groundwater is still a source of heavy metal contaminants, e.g., Cd, Ni, Co, Cu and Zn, to nearby ecosystems. However, natural attenuation of heavy metals is occurring in Mn oxide rich soils and sediments ranging in pH from 5 to 7. While microorganisms readily oxidize Mn(II) and precipitate Mn oxides at pH ~7 under oxic conditions, few studies describe Mn(II)-oxidizing bacteria (MOB) at pH ~5 and/or in the presence of heavy metals. In this study we (1) isolated MOB from the contaminated Ronneburg area at pH 5.5 and 7 and (2) evaluated the biological formation of Mn oxides. We isolated nine MOB strains at pH 7 (members of the Proteobacteria, Actinobacteria, Bacteroidetes, and Firmicutes phyla) and a single isolate at pH 5.5 (Oxalobacteraceae isolate AB_14, within the β-Proteobacteria). LA-ICP-MS showed that all isolates accumulated Mn and Fe in their biomass. However, the Oxalobacteraceae isolate AB_14 oxidizes more Mn without additional Fe in the medium. Preliminary FTIR analysis indicated that all isolates formed precipitates, which showed absorption bands that were characteristic for birnessite. High resolution TEM showed variable morphology of precipitates and EDS confirmed the presence of Mn oxides. Isolate AB_14 was not surrounded with precipitates whereas our Actinobacteria isolate AB_18 was encrusted with Mn oxides. Electron diffraction is currently being used to confirm the presence of birnessite and other Mn oxide phases. This, the first known report of any organism capable of Mn oxidation at low pH, demonstrated that MOB can be involved in the natural attenuation of both moderately acidic and neutral pH soils and sediments via the formation of biogenic Mn oxides. Future work will fully evaluate the minerals formed in this process as well

    A study of seepage occurring in an adit at the Nopal I uranium mine in Chihuahua, Mexico, was conducted as part of an integrated natural analogue study to evaluate the effects of infiltration and seepage on the mobilization and transport of radionuclides. An instrumented seepage collection system and local automated weather station permit direct correlation between local precipitation events and seepage. Field observations recorded between April 2005 and December 2006 indicate that seepage is highly heterogeneous with respect to time, location, and quantity. Seepage, precipitation, and fracture data were used to test two hypotheses: (1) that fast flow seepage is triggered by large precipitation events, and (2) that an increased abundance of fractures and/or fracture intersections leads to higher seepage volumes. A few zones in the back adit recorded elevated seepage volumes immediately following large (>20 mm/day) precipitation events, with transit times of less than 4 h through the 8-m thick rock mass. In most locations, there is a 1-6 month time lag between the onset of the rainy season and seepage, with longer times observed for the front adit. There is a less clear-cut relation between fracture abundance and seepage volume; processes such as evaporation and surface flow along the ceiling may also influence seepage.

    The main objective of this work is to investigate the uptake of several radionuclides by the vegetation characteristic of a dehesa ecosystem in uranium mining-impacted soils in Central-West of Spain. The activity concentration for 238U, 226Ra, 210Pb, 232Th, and 224Ra was measured in soil and vegetation samples using a Canberra n-type HPGe gamma-ray spectrometer. Transfer factors of natural radionuclides in different tissues (leaves, branches, twigs, and others) of native plants were evaluated. From these data, the influence of the mine, the physicochemical parameters of the soils and the type of vegetation were analyzed in order to explain the accumulation of radionuclides in the vegetation. A preferential uptake of 210Pb and 226Ra by plants, particularly by trees of the Quercus species (Quercus pyrenaica and Quercus ilex rotundifolia), has been observed, being the transfer factors for 226Ra and 210Pb in these tree species higher than those for other plants (like Pinus pinaster, Rubur ulmifolius and Populus sp.). The analysis of radionuclide contents and transfer factors in the vegetation showed no evidence of influence of the radionuclide concentration in soils, although it could be explained in terms of the type of plants and, in particular, of the tree's species, with special attention to the tree's rate of growth, being higher in slow growing species.

    Radioactivity contamination originating from the coal fired power plant and its waste dumps located in a bay of the Adriatic which is due to geographical characteristics sensitive to any kind of pollution including radioactivity is discussed. Investigations of coal used in regular plant operation and of solid incombustile ash and slag showed increased concentrations of natural radioactivity which may cause general environmental contamination of the bay as well as contamination of the marine environment of this part of Croatian Adriatic. There are two coal slag and ash piles, one of them was closed and covered by soil and the other is a still operating pile. The location of both piles presents a considerable environmental problem: situated close to the seaside, slag and ash are accumulating in the littoral zone and, in the case of operating pile, are being filled up directly into the sea. The aim of this study was to determine the radioactivity level at the ash and slag deposits and to assess the risk of increased radioactivity for the inhabitants of the nearby urban area, for the plant workers and general environment of the bay including the marine environment of this part of the Croatian Adriatic.

    A systematic study devoted to 137 Cs, 90 Sr, 241 Am, 239+240 Pu radionuclides in vegetation cover from several spots of the Semipalatinsk test site (STS) is summarised in this paper, highlighting the main findings obtained. The analysed spots are characterized by various types of radioactive contamination. Transfer factors (Tf) required for the quantitative description of the radionuclides transition from the soil to aboveground plant parts were determined, being found that, on average, the minimum Tf for all the radionuclides concerned were determined on the "Experimental Field" ground, followed by the determined ones in the "plumes" of radioactive fallout and in the conditionally "background" territories analysed. The highest transfer factors were characteristic of zones of radioactive streamflows and places of warfare radioactive agent (WRA) tests. On the other hand, ordering the radionuclide transferring factors in descending order, the following sequence was obtained: 90 Sr Tf > Cs Tf >  239+240 Pu Tf >  241 Am Tf, with the 90 Sr Tf, on the average, exceeding the 137 Cs Tf by 8 times and exceeding the 239+240 Pu Tf by up 16 times. 239+240 Pu Tf values were up to 3 times higher than the 241 Am Tf. The exception to the indicated radionuclide Tf descending order corresponded to places of WRA tests where Tf of radionuclides of interest by plants follows the sequence 90 Sr >  239+240 Pu >  137 Cs.

    Monitored Natural Attenuation (MNA) applied to sites were groundwater have been affected by a fuel spill from an Industrial Underground Storage Tank (UST) is economically viable and a reliable methodology to achieve remediation goals. MNA process consists in the control of naturally occurring physical, chemical , and biological processes and is based in the knowledge of the processes that take place and reduce the charge of compounds derived from fuel in the site of study. Because the risk for Human Health and Ecosystem define the concept of contaminant, during MNA special attention has to be taken on concentration diminution of that are or could become contaminants and in this way is possible to perform Risk-Based Land Management (RBLM) by measuring both, the primary lines of evidence (shrinking or stable plume of contaminants) and secondary lines of evidence (given by geochemical indicators in the plume). Once, evidences have been gathered, is possible to calculate the rate of attenuation of contaminants and evaluate if admissible risk is reached an in a reasonable time framework, in order to propose MNA as a unique remediation or combined with other procedures to apply to an affected site. The objective of the present study is to evaluate the application of MNA to an active industrial site in order to develop a RBLM able to assess that the risk for Human Health and ecosystem are acceptable. The added attractive of this methodology is the non-intrusiveness that allows not to stop the industrial activity. The site considered in our study is in an active company located about 15 Km to NW from Barcelona, Spain.The company has a buried UST containing heavy fuel oil for energetic use. During 2002 a general soil impact study revealed that subsoil and groundwater close to the UST were affected by hydrocarbon losses from the tank and in January 2003 the fuel of the tank was emptied by pumping. The free phase of fuel floating on groundwater remained on the aquifer. As a

    The National Petroleum Reserve No. 3 site (NPR-3) near Casper, Wyoming is being prepared for transfer to private industry. Remediation of the NPR-3 site has already begun in anticipation of this transfer. This document describes the characterization of the NPR-3 site for Naturally Occurring Radioactive Materials (NORM). Data generated on radionuclide concentrations and radon emanation may be used to determine disposal options and the need for remediation at this site. A preliminary gamma survey of the NPR-3 site was conducted to identify areas of potential NORM contamination. Based on these gamma surveys, two general areas of NORM contamination were found: the North Water Flood area and the BTP-10 produced water discharge steam. A maximum surface exposure rate of 120 {micro}R h{sup -1} was observed in the North Water Flood area, with the highest readings found along the drainage channel from the area. Exposure rates dropped to background quickly with increasing distance from the center of the drainage. The maximum observed exposure rate in the BTP-10 produced water drainage was 40 {micro}R h{sup -1}. Soil and sediment sampling were concentrated in these two areas. All samples were analyzed for concentration of {sup 226}Ra, {sup 228}Ra, and {sup 40}K. Maximum {sup 226}Ra concentrations observed in the samples collected were 46 pCi g{sup -1} for soil and 78 pCi g{sup -1} for sediment. Concentrations in most samples were considerably lower than these values. Radon emanation fraction was also measured for a randomly selected fraction of the samples. The mean Rn emanation fraction measured was 0.10, indicating that on average only 10 percent of the Rn produced is released from the medium. Based on the results of these analyses, NORM contamination at the NPR-3 site is minimal, and appears to be restricted to the two general areas sampled. Concentrations of NORM radionuclides found soils and sediments in these two locations do not justify remedial actions at present

    Full Text Available For the past several years since September 11, 2001, large numbers of people from across the continent and around the world have visited the site of the devastated World Trade Center in New York. Scholars in religious studies and the social sciences have noticed that there were and continue to be (though less so over time religious aspects to the observances and performances of visitors to ‘Ground Zero’, as the site of the former World Trade Center almost immediately came to be called. A central argument of this article is that the ongoing stream of visitors to Ground Zero, strictly speaking, does not qualify this phenomenon as a pilgrimage in the traditional religious sense; it is more akin to the growing phenomenon of religious tourism, although it is not exactly that either. Nonetheless the event of 9/11 generated many ritualized activities; the article will also address the pro­cess scholars call ‘ritualization’ and related terms in ritual studies. Although ritualized performances at Ground Zero do not amount to a pilgrimage in the narrow sense that historians of religion mean when they analyse traditional pilgrimages, such as the Hajj to Mecca, or following the Via Dolorosa in Jerusalem, visiting Ground Zero has taken on both secular and religious elements.

    A study has been carried out to determine the natural occurring radioactivity and heavy metal at an industrial site area Gebeng, Pahang. Sampling has been done in four different stations. This study has been carried out to determine the natural radioactivity ( 238 U, 232 Th, 40 K and 226 Ra) and heavy metal in soil sample. Natural radioactivities were determined using Gamma Spectrometry System, the heavy metal determination was done using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The result for analysis radioactivity concentration showed that Uranium-238 were in the range of 28.18 ± 4.78 Bq/ kg - 39.63 ± 4.79 Bq/ kg, while the concentration for Thorium-232 were in the range of 45.66 ± 5.49 Bq/ kg - 72.43 ± 9.47 Bq/ kg and for the Radium-226, the concentration were in the range of 8.93 ± 1.15 Bq/ kg - 14.29 ± 2.61 Bq/ kg. The concentration of Potassium-40 were in the range of 51.06 ± 12.18 Bq/ kg - 426.28 ± 137.70 Bq/ kg. 8 heavy metals have been found from the four different stations which are Al, Fe, V, Mn, Cr, Cu, Zn and Pb. Fe show the highest concentration among the other heavy metal while Pb show the lowest concentration. From this study, the specific activities of natural radionuclide in almost all stations were below the world limit average for soil, which is 35 Bq/ kg for Uranium-238 and Radium-226, while Thorium-232 and Potassium-40 were above the world limit average which are 30 Bq/ kg and 400 Bq/ kg.

    SIXEP has been conducted by British Nuclear Fuels plc at its Sellafield reprocessing site as part of its committment to reduce radioactive discharges to the Irish Sea. An extensive development program identified the natural ion exchange mineral clinoptilolite, from a particular deposit in California now owned by Tenneco Specialty Minerals, as the most suitable for use in SIXEP to extract caesium and strontium from spent nuclear fuel storage pond water. Close cooperation with the supplier in a Quality Assurance scheme ensured the supply of a fully-characterised, high grade ion exchanger. Since SIXEP commenced treating pond water on 28 May 1985, the plant has performed well, exceeding the design expectation in terms of discharge reduction and availability

    Objective of this study is to provide an evidence-based analysis of the current status and future perspectives of scarless urological surgery. A PubMed search has been performed for all relevant urological literature regarding natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS). In addition, experience with LESS and NOTES at our own institution has been considered. All clinical and investigative reports for LESS and NOTES procedures in the urological literature have been considered. A wide variety of clinical procedures in urology have been successfully completed by using LESS techniques. Thus far, experience with NOTES has largely been investigational, although early clinical reports are emerging. Further development of instrumentation and platforms is necessary for both techniques to become more widely adopted throughout the urological community.

    Full Text Available The article focuses on the formation of modern Muslim political identity on the macro-po-litical and individual levels. The author explores the relation between its Islamic and state-national levels. It is shown that this relationship is of dynamic nature and that at present both these levels are significantly differentiated: nationalism outgrows the framework of state nationalism and gradually acquires civil dimension, while the Islamic layer, losing its significance as the only source of identification and self-identification for Muslims, acquires new socio-political content. The latter is reflected in the development of “Islamist pluralism”. It is noted that the ascriptive orientations to kin-groups, ethnic groups and clans remain significant and especially vibrant in the times of political turbulence.

    Full Text Available The present work aims to analyze and describe the human experience of the time in the sacred and the profane from the thought of the philosopher and historian Mircea Eliade. The research has as its starting point the observation of duality sacred/profane statement that results in two modes of being in the world, namely the religious and non-religious. Thus, we aimed to assess the extent of heterogeneous temporality in the life of man and the religious and man without religion. However, the understanding of this experience can be established only when one realizes the importance of constructions of temples, religious festivals, rituals and myth presented as one of the sacred language that only makes sense because of the inhomogeneity of time.

  17. Tuskegee as Sacred Rhetoric: Focal Point for the Emergent Field of African American Religion and Health.

    2018-02-01

    Scholars in African American religion engage the Tuskegee Syphilis Study as the focal point of the African American experience in institutional medicine. Seeking a way forward from this history and its intentional evil, the author proposes to position Tuskegee as a form of Lynch's culturally contextual sacred rhetoric to make use of its metaphoric value in the emerging field of African American religion and health. In this broader meaning-making frame, Tuskegee serves as a reminder that African American religious sensibility has long been an agential resource that counters abuse of the Black body. It also acknowledges the complex decisions facing African American clinical trial participants.

    Full Text Available This article aims to identify the numerous quotations from sacred texts appearing in Emilio Villa’s 17 variazioni. Indeed, the 1955 collection of poems offers a wide range of references to Biblical sources and archaic cosmogonic myths, ancient symbologies and eschatological conjectures. The poet is both the translator and the interpreter of these texts, which the collection mixes and interlinks in the shape of an enigma. This air of mystery seems to deny any definitive revelation, highlighting instead a plurality of points of view that ultimately result in Apocalypse.

  1. Mineral formation on metallic copper in a `Future repository site environment`: Textural considerations based on natural analogs

    Copper mineral formation in the Swedish `repository site environment` is discussed. Special attention is given to ore mineral textures (=the spatial relation among minerals), with examples given from nature. It is concluded: By analogy with observations from natural occurrences, an initial coating of Cu-oxide on the canister surface (because of entrapped air during construction) will probably not hinder a later sulphidation process. Early formation of Cu-sulphides on the canister surface may be accompanied by formation of CuFe-sulphides. The latter phase(s) may form through replacement of the Cu-sulphides or, alternatively, by means of reaction between dissolved copper and fine-grained iron sulphide (pyrite) in the surrounding bentonite. Should for some reason the bentonite barrier fail and the conditions become strongly oxidizing, we can expect crustifications and rhythmic growths of Cu(II)-phases, like malachite (Cu{sub 2}(OH){sub 2}CO{sub 3}). A presence of Fe{sup 2} in the clay minerals making up the bentonite might prove to have an adverse effect on the canister stability, since, in this case, the bentonite might be expected to act as a sink for dissolved copper. The mode of mineral growth along the copper - bentonite interface remains an open question.

    Caprock integrity is an important constraint on the long-term performance of natural and engineered carbon dioxide (CO{sub 2}) sequestration sites. Influxes of CO{sub 2} can lead to concomitant geochemical alteration and geomechanical deformation of the caprock and degrade seal integrity. In this study, reactive transport modelling was used to assess the evolution of caprock permeability. The model was based on mathematical models of the coupled physical and chemical processes catalyzed by an influx event, along with supporting geochemical databases and a distinct-element geomechanical model. Geomechanical contribution was evaluated within a full system analysis of coupled hydrological and geochemical processes for Sleipner-like settings, and then analyzed as a function of hydrological processes, key reservoir properties, and CO{sub 2} influx parameters. The net effect of the geomechanical and geomechanical contributions on caprock integrity was then evaluated for both natural and engineered storage scenarios. Results of the study showed that CO{sub 2} influx-triggered geochemical and geomechanical processes act in opposition to enhance and degrade hydrodynamic seal capacity through aperture narrowing and widening of microfractures. The extent of geochemical enhancement was independent of the reservoir characteristics that distinguished saline-aquifer from enhanced oil recovery and CO{sub 2} sequestration settings. However, while the extent of geochemical alteration was nearly independent of the filling mode, geomechanical deformation processes were more pronounced in engineered storage scenarios. Results suggested that the secure caprocks of natural CO{sub 2} accumulation settings may be incapable of providing effective seals for engineered injection processes. The pressure increase associated with CO{sub 2} accumulation in any compartmentalized system resulted in the net geomechanical aperture widening of caprock microfractures. It was concluded that the

    Document available in extended abstract form only. A key aspect of a Deep Geologic Repository (DGR) safety case is the ability to develop and communicate an understanding of the geologic stability and resilience to change at time frames relevant to demonstrating repository performance. As part of an on-going Environmental Assessment, Ontario Power Generation (OPG) recently completed site-specific investigations within an 850 m thick Paleozoic sedimentary sequence beneath the Bruce nuclear site for the proposed development of a DGR for Low and Intermediate Level Waste (L and ILW). As envisioned, the shaft-accessed DGR would be excavated at a nominal depth of 680 m within the low permeability Ordovician argillaceous limestone of the Cobourg Formation, which is overlain by more than 200 m of low permeability Ordovician shale. The geo-scientific investigations revealed a relatively undeformed and laterally continuous architecture within the sedimentary sequence at the repository scale (1.5 km 2 ) and beyond. This paper explores the predictable nature of the sedimentary sequence that has contributed to increasing confidence in an understanding of the spatial distribution of groundwater system properties, deep groundwater system evolution and natural barrier performance. Multi-disciplinary geo-scientific investigations of the Bruce nuclear site were completed in 3 phases between 2006 and 2010. The sub-surface investigations included a deep drilling, coring and in-situ testing program and, the completion of a 19.7 km (9 lines) 2-D seismic reflection survey. The drilling program involved 6 (150 mm dia.) deep boreholes (4-vertical; 2 inclined) that were extended through the sedimentary sequence from 4 drill sites, arranged around the 0.3 km 2 footprint of the proposed repository. The more than 3.8 km of rock core (77 mm dia.) retrieved have provided, in part, a strong basis to understand bedrock lithology and mineralogy, facies assemblages, structure, and oil and gas

    This work studies the role of mineral particles collected in the region of Patagonia (Neuquén, Argentina) as ice nuclei particles (INPs) by immersion freezing mode. The particle immersion-freezing ability was analyzed under laboratory conditions by using an established drop-freezing technique. Mineralogical composition was characterized by using X-ray diffraction and electron micro probe analysis. Dynamic light scattering was used to determine the grain size distribution of particles, while the N2 adsorption and methylene blue adsorption methods were applied to determine their specific surface area. Water droplets of different volumes containing different concentrations of particles were cooled until droplets were frozen. For all the analyzed drop volumes, an increase in the freezing temperature of the drops was observed with increasing dust concentration. In the same way, the freezing temperature increased when the drop volume was increased at constant dust concentration. Both behaviors were linked to the availability of active sites in the particles. A plateau in the freezing temperature was observed at high suspension concentration for all the drop volumes. This plateau was related to the aggregation of the particles when the suspension concentration was increased and to the consequent decrease in the number of active sites. The active sites per unit of surface area were calculated and reported. For the studied range of temperature, results are in agreement with those reported for different sites and particles. From the chemical and morphological analysis of the particle components and the results obtained from the literature, it was concluded that even though montmorillonite was the main mineral in the collected sample, the accessory minerals deserve to be analyzed in detail in order to know if they could be responsible for the ability of the collected soil particles to act as INPs. Considering that the region of Patagonia has been identified as an important

    Several intriguing developments mark the role and expression of religion and spirituality in society in recent years. In what were deemed secular societies, flows of increased sacralization (variously referred to as 'new', 'alternative', 'emergent' and 'progressive' spiritualities) and resurgent globalizing religions (sometimes with fundamentalist expressions) are resulting in unprecedented plurality. These shifts are occurring in conjunction with increasing ethnic diversity associated with global migration, as well as other axes of difference within contemporary society. Democratic secular nations such as Canada are challenged to achieve social cohesion in the face of growing religious, spiritual and ethnic diversity. These challenges are evident in the high-paced, demanding arena of Health care. Here, religious and spiritual plurality enter in, sometimes resulting in conflict between medical services and patients' beliefs, other times provoking uncertainties on the part of healthcare professionals about what to do with their own religiously or spiritually grounded values and beliefs. In this paper, we present selected findings from a 3-year study that examined the negotiation of religious and spiritual pluralism in Health care. Our focus is on the themes of 'sacred' and 'place', exploring how the sacred - that which is attributed as special and set apart as it pertains to the divine, transcendence, God or higher power - takes form in social and material spaces in hospitals. © 2011 Blackwell Publishing Ltd.

  8. Compassionate love as a mechanism linking sacred qualities of marriage to older couples' marital satisfaction.

    Previous work has underscored the robust links between sanctification of marriage and marital outcomes, and recent developments in the literature suggest that compassionate love, which is important for intimate relationships, may act as a mediator of that relationship. Accordingly, the current study used actor-partner interdependence models to examine the relationship between a spiritual cognition (i.e., perceived sacred qualities of marriage) and marital satisfaction, and to determine whether that relationship is mediated by compassionate love, in a sample of older married couples (N = 64). Results revealed that wives' greater sacred qualities of marriage were significantly and positively linked to marital satisfaction on the part of both spouses, and that these links were partially mediated by couples' reports of compassionate love. These findings highlight the importance of moving beyond simply establishing the existence of the link between global markers of involvement of religion and marriage to understanding how specific spiritual cognitions may foster better relationship quality, especially among older couples.

  9. Soil as natural heat resource for very shallow geothermal application: laboratory and test site updates from ITER Project

    2017-04-01

    Nowadays renewable energy resources for heating/cooling residential and tertiary buildings and agricultural greenhouses are becoming increasingly important. In this framework, a possible, natural and valid alternative for thermal energy supply is represented by soils. In fact, since 1980 soils have been studied and used also as heat reservoir in geothermal applications, acting as a heat source (in winter) or sink (in summer) coupled mainly with heat pumps. Therefore, the knowledge of soil thermal properties and of heat and mass transfer in the soils plays an important role in modeling the performance, reliability and environmental impact in the short and long term of engineering applications. However, the soil thermal behavior varies with soil physical characteristics such as soil texture and water content. The available data are often scattered and incomplete for geothermal applications, especially very shallow geothermal systems (up to 10 m depths), so it is worthy of interest a better comprehension of how the different soil typologies (i.e. sand, loamy sand...) affect and are affected by the heat transfer exchange with very shallow geothermal installations (i.e. horizontal collector systems and special forms). Taking into consideration these premises, the ITER Project (Improving Thermal Efficiency of horizontal ground heat exchangers, http://iter-geo.eu/), funded by European Union, is here presented. An overview of physical-thermal properties variations under different moisture and load conditions for different mixtures of natural material is shown, based on laboratory and field test data. The test site, located in Eltersdorf, near Erlangen (Germany), consists of 5 trenches, filled in each with a different material, where 5 helix have been installed in an horizontal way instead of the traditional vertical option.

  10. Recovery of contaminated wetland soils at the Savannah River Site by natural rainfall: An experimental, toxicological study

    This study was conducted at the Department of Energy Savannah River Site in South Carolina. Seepage basins at the SRS F-Area received liquid effluent from the 1950s to 1988. This effluent was typically acidic, containing high amounts of total dissolved ions, low levels of tritium and other radioactive elements, and trace levels of various heavy metals. Sodium (from NaOH), and aluminum [from soil matrix reduction due to acid leachate] were at particularly high levels in the outcropping water. The effluent gradually seeped down to the water table and subsequently outcropped along the edge of a forested wetland bordering Four Mile Creek. A laboratory study was conducted to evaluate the potential for natural remediation of contaminated wetland soils by rainfall. Contaminated soils were collected and leached repeatedly with rainwater. After 6 leachings the leachate was observed to be non-toxic to lettuce seedlings, whereas the initial leachate was very toxic. These results suggest that more detailed studies on leaching as a remediation technique would be beneficial. 6 refs., 2 figs., 3 tabs

    Deltorphins are endogenous linear heptapeptides, isolated from skin extracts of frogs belonging to the genus Phyllomedusa, that have a higher affinity and selectivity for delta opioid binding sites than any other natural compound known. Two deltorphins with the sequence Tyr-Ala-Phe-Asp(or Glu)-Val-Val-Gly-NH2 have been isolated from skin extracts of Phyllomedusa bicolor. The alanine in position 2 is in the D configuration. These peptides, [D-Ala2]deltorphins I and II, show an even higher affinity for delta receptors than the previously characterized deltorphin, which contains D-methionine as the second amino acid. These peptides show some similarity to another constituent of Phyllomedusa skin, dermorphin, which is highly selective for mu-opioid receptors. These peptides all have the N-terminal sequence Tyr-D-Xaa-Phe, where D-Xaa is either D-alanine or D-methionine. While this structure seems to be capable of activating both mu and delta opioid receptors, differences in the C-terminal regions of these peptides are probably responsible for the observed high receptor selectivity of dermorphin and deltorphin.

    In the paper genetic variability of natural population of chironomidae inhabiting in waters on the territory of Semipalatinsk test site (STS) is studied. Ten Chironomini species of Chironomidae subfamily and one species of Tanypodinae subfamily were identified using cyto-taxonomic methods of analysis. Cytophotomap of polythene chromosomes of salivary glands were established for four species: Glyptotendipes salinus, Captochironomus setivalva, Camptochriomonus tentas and Chironomus plumosus. For the first time a new previously unknown species of Chironomus gender, and namely C, genelenus 1. sp. n. was described and a cytophotomap of its polythene chromosomes was established. A detailed quantative and qualitative analysis of chromosome polymorphism was carried out and the spectrum and frequency of the disk sequences and genotypic combination were identified. New evidence on change in the polythene chromosomes structure were revealed in certain Chironomini species dwelling in the radioactively contaminated water bodies of STS: rare, unique disk sequences of chromosomes were found, a series of specific homo zygote and heterozygote inversions were observed, which evidently resulted from long-term adaptive selection under conditions of the chronic ionizing radiation. Increase of in frequency of structural mutations of chromosomes was found in mitotic cells of imago disk of Chironomini larvae is revealed. This increase indicates that at the STS many population of benthos organisms are directly affected by the ionizing radiation

    The extinction date of the giant flightless New Zealand ratite bird, the crested moa (Pachyornis australis), is of considerable interest because the youngest verified remains are dated to the Pleistocene–Holocene transition c. 10,000 yr BP, which was characterised by severe climatic and habitat change, and are considerably earlier than the late Holocene extinctions of the other eight moa species. Analysis of a partial crested moa skeleton (NMNZ S23569) from Castle Keep Entrance, Bulmer Cave System, Mount Owen, South Island, generated a radiocarbon date of 564±26 yr BP (544-508 cal yr BP; 95.4% AD 1396-1442). As a result the Bulmer Cave specimen represents the youngest moa yet found from a natural site in New Zealand. Combined with additional crested moa remains dated to the late Holocene from Cheops Cave (Mount Arthur) and Magnesite Quarry (Cobb Valley), this indicates that crested moa did not go extinct during the Pleistocene–Holocene transition but survived until after Polynesian colonisation in c. AD 1280. The new radiocarbon dates reported here have important implications for the timing of moa extinction and the late survival of moa in alpine areas of New Zealand.

    The contact between an obsidian flow and a steep-walled tuff canyon was examined as an analogue for a high-level waste repository. The analogue site is located in the Valles Caldera in New Mexico, where a massive obsidian flow filled a paleocanyon in the Battleship Rock Tuff. The obsidian flow provided a heat source, analogous to waste panels or an igneous intrusion in a repository, and caused evaporation and migration of water. The tuff and obsidian samples were analyzed for major and trace elements and mineralogy by INAA, XRF, x-ray diffraction, and scanning electron microscopy and electron microprobe. Samples were also analyzed for D/H and 39 Ar/ 40 Ar isotopic composition. Overall, the effects of the heating event seem to have been slight and limited to the tuff nearest the contact. There is some evidence of devitrification and migration of volatiles in the tuff within 10 m of the contact, but variations in major and trace element chemistry are small and difficult to distinguish from the natural (pre-heating) variability of the rocks

    Developing a sufficient understanding of environmental processes and exposure pathways that permit observations to be explained and robust predictions to be made over spatial and temporal scales is a clear challenge that radioecology needs to address. This scientific challenge has been developed as a separate section of the Strategic Research Agenda (SRA) a document produced by the STAR Network of Excellence in Radioecology that outlines a suggested prioritisation of research topics in radioecology. Reality is that in order to bring the SRA to fruition, besides considerable resources and time, an available proving ground is required. The sole sources of such data are areas affected by nuclear accidents but the conditions provided do not follow requirements for scientific experiment. On the other hand, it is hard to imagine anyone deliberately releasing substantial amount of radioactivity into environment in order to observe what would happen- Some of coal mines at Upper Silesia Coal Basin have discharged radium reach brines continuously for many years. The total amount of radium released to inland water is quite well known and varies with time or exploitation conditions. This phenomenon has been observed for more than 30 years and many contaminated sites being in different state were identified. Natural radionuclides (mainly radium isotopes) present in mine water after its release into the environment are subject to different chemical and/or physical processes influencing their final fate. The processes of concern are e.g. precipitation, sedimentation, adsorption, absorption, ion exchange, desorption, leaching, erosion, sequential decay etc. Based on physical and chemical rules, available data and real environmental conditions the key processes that govern radium and its progeny behaviour after discharge with mine water, associated transfers among environmental compartments and resulting exposures of both non-human and humans populations have been identified.

    Colored dissolved organic matter (CDOM) on the continental shelf and slope can serve as a marker for fresh water influence, indicate the presence of hydrocarbons, and provide important clues about nutrient content and organic matter cycling. Autonomous underwater vehicles such as gliders allow for subsurface measurement of CDOM fluorescence for weeks to months; these time series may be especially valuable in the northern Gulf of Mexico, where CDOM inputs of both terrestrial and oil and gas sources can be significant. Data from a recent glider deployment near a natural seep site (GC600) on the continental slope over 180km from shore suggest simultaneous influence of Mississippi plume water and hydrocarbon inputs in the upper 200m, with variability in fluorescence at a range of vertical and temporal scales. We will explore patterns in spatial and temporal variability of glider-measured hydrography, dissolved oxygen, and bio-optical data (CDOM, chlorophyll-a, backscatter fluorescence), and use their combination to infer a terrigenous and/or fossil fuel source(s). Taking advantage of a combination of satellite sea surface temperature, ocean color, wind, and data from moored and mobile platforms, we will examine physical controls on transport and vertical mixing of CDOM and the potential role of nonlinear mesoscale eddies, which can trap water in their interior and may transport river- or hydrocarbon-derived CDOM over long distances. The combined data set will be used to consider and potentially constrain the effect of photodegradation and other biogeochemical causes for CDOM fluorescence variability in the upper 200m.

    Whole body monitoring of a worker showed an apparent internal contamination with a considerable amount of 95 Zr- 95 Nb. Inhalation exposure was suspected to have taken place about a week earlier when he had last worked in the radioactive area. Unexpected fast clearance indicated by the third periodical weekly follow up monitoring was considered to be an abnormal behaviour. Investigations revealed an external contamination on a sacred thread, which the worker was putting on across his thorax and not removing it at the time of bath due to religious considerations. These studies have underscored that short term follow up measurements data should be critically scrutinized and a caution should be exercised in the interpretation such data particularly in case of such relatively short lived radionuclides.

    Full Text Available Perhaps no single judge in recent years has embodied the intricacies and difficulties of the cultural life of the law as much as American Supreme Court Justice Antonin Scalia. While common law judges have traditionally acquired status—and cultural relevance—from the significance, eloquence and forcefulness of their judicial opinions, Justice Scalia took an altogether different route. Both on and off the bench, he pushed the limits of legal and political legitimacy. He did this through a strict adherence to what we call a “judicial mandate,” flamboyant but engaging writing, biting humor and widespread marketing of his originalist and textualist interpretative theories. This article chronicles these features of Scalia’s jurisprudence and public life more generally, ultimately characterising the late justice as a “sacred symbol” in American legal and political circles, and beyond.

  5. The Camouflage of the Sacred in the Short Fiction of Hemingway

    2014-01-01

    Full Text Available This essay examines the short fiction of Ernest Hemingway in the light of Mircea Eliade’s notion of the camouflage of the sacred and the larval survival of original spiritual meaning. A subterranean love pulsates beneath the terse dialogue of Hemingway’s characters whose inner life we glimpse only obliquely. In the short play (“Today Is Friday” and four short stories (“The Killers,” “A Clean Well-Lighted Place,” “Old Man at the Bridge,” and “The Light of the World,” discussed here, light imagery, biblical allusions, and the figure of Christ, reveal a hidden imaginary universe. This sacral dimension has been largely overlooked by critics who dwell on the ostensible spiritual absence that characterizes Hemingway’s fiction.

  6. The Dredging of the Sacred Cenote of Chichen Itzá 1904-1914

    2017-09-01

    Full Text Available This article analyzes the “restoration” of a treasure of incalculable value, taken from Chichen Itzá’s Sacred Cenote with the help of a primitive dredge installed along its edge by Edward H. Thompson, then the U.S. consul in Progreso, and financed by Harvard University’s Peabody Museum and private collectors from the Boston area. This “restoration” began in 1904 and continued up until 1907, with periodic resumptions up until 1909, the year in which Thompson resigned from his consular position, which marked the weakening of the network of complicity that he had been weaving since 1875 to allow him to illegally export hundreds of Maya pieces to the University of Cambridge. The article concludes in 1914, when the violence of the Mexican Revolution unintentionally put an end to the looting of Chichén Itzá.

  7. Sacred Psychotherapy in the “Age of Authenticity”: Healing and Cultural Revivalism in Contemporary Finland

    2011-10-01

    Full Text Available Like other European countries, contemporary Finland has witnessed an explosion of healing modalities designatable as “New Age” (though not without profound controversy, [1]. This paper focuses on Finnish courses in lament (wept song, tuneful weeping with words that combine healing conceived along psychotherapeutic lines and lessons from the lament tradition of rural Karelia, a region some Finns regard as their cultural heartland. A primary goal of the paper is to explicate a concept of “authenticity” emerging in lament courses, in which disclosing the depths of one’s feelings is supported not only by invoking “psy-“ discourses of self-help, but also by construing the genuine emotional self-disclosure that characterizes neolamentation as a sacred activity and a vital contribution to the welfare of the Finnish people.

  8. To have and to hold: possessing the sacred in the late renaissance

    Full Text Available Private devotional art of the early 17th century often found its place in the galleries of noblemen and women whose diverse collections were symbols not only of stylistic taste, but of their owners’ exhaustive curiosity. In these domestic settings, boundaries between sacred and secular were permeable, as the unprecedented physical intimacy portrayed in popular religious subjects such as St Matthew and the Angel, the Stigmatisation of St Francis, or Christ’s Agony in the Garden reveal. Representations of the latter reminded viewers of Christ’s human, corporal suffering and suggested a model of resolve strengthened by prayer. The Agony in the Garden appears on the interior of Jacopo Ligozzi’s virtuosic Portable Altar with Carrying Case (1608, likely a Medici gift presented to the Austrian court in anticipation of the marriage of archduchess Maria Maddalena to soon-to-be grand duke Cosimo II. Adorned with lavish botanical motifs on its exterior, the Altar’s potency as a sacred possession was redoubled by the owner’s tactile revelation of the portrayal of Christ supported by an Angel contained inside the case. Comprised of wood, oil on copper, and pietre dure inlay, it is an object intended to be held, opened, and experienced. This paper suggests that Ligozzi’s selective combination of sumptuous materials and choice of subject matter – botanical illustration and Christological iconography – allowed the object to appeal to the full sensorium, and therefore to function as efficaciously as a devotional aid as it did as a curiosity among other rare collectibles.

  9. Sacred byzantine music and its influence on old East Slavic Orthodox music

    Full Text Available Sacred Byzantine music originates from three sources: “the liturgy of heaven”, synagogue music as well as old Greek theory of music and lays at the bottom of the East Slavs liturgical chant. The tonal base of the Byzantine music formed tetrachords. From them the so called Diatonic mode took shape. It was the easiest and the most popular sound arrangement steming from Greek music. The Cristian Church considered it to be in accordance with its Spirit and needs. From the tetrachords mentioned above other tones were created, namely Doric tones, Lydian, Phrygian and Mixolydian and, together withall their derivatives they gave beginning to the Oktoechos tradition. Byzantine music was flourishing in monasteries and in town areas andmany different forms were elaborated on like troparions, kontakions, stichiry, canons, etc. If one speaks about composers then certainly some names cannot be omitted. These are: St. Anatolius (Patriarchof Constantinople, St. Andrew of Crete, St. Romanos the Melodist,St. Sophronius of Jerusalem and, above all, St. John of Damascus who collected and systematized the liturgical chants creating mentioned Oktoechos. The acceptance of the Greek form of Christianity by Rus’ caused a cultivation of the sacred Greek vocal art on its territory which manifested in a form of so called Znamenny chant. This type of chant was at first similar to the Greek model but later on it moved away from it. Musical notation of the Old East Slavic singing was based on neumes which names in Old East Slavic have changed a little and only few survived. Furthermore, liturgical note books together with their genre and music content have been taken over from Byzantium. Especially visible in the Old East Slavic monody, Byzantine patterns were pervading also the later polyphony which proves they were always current. Moreover, this allows to claim that Rus’ became the real successor of the Greek Orthodox traditions in new circumstances of sacral

    Despite growing recognition that mineral sites restored for nature conservation can enhance local biodiversity, the wider societal benefits provided by this type of restoration relative to alternative options are not well understood. This study addresses this research gap by quantifying differences in ecosystem services provision under two common mineral site after-uses: nature conservation and agriculture. Using a combination of site-specific primary field data, benefits transfer and modelling, we show that for our sites restoration for nature conservation provides a more diverse array of ecosystem services than would be delivered under an agricultural restoration scenario. We also explore the effects of addressing different conservation targets, which we find alter the provision of ecosystem services on a service-specific basis. Highly species-focused intervention areas are associated with increased carbon storage and livestock grazing provision, whereas non-intervention areas are important for carbon sequestration, fishing, recreation and flood risk mitigation. The results of this study highlight the wider societal importance of restored mineral sites and may help conservation managers and planners to develop future restoration strategies that provide benefits for both biodiversity and human well-being.

    Mc Leod confirmed, with physics, his models for vision, and for electromagnetic artifacts, by traditional methods, associated with phenomena like tornados, hurricanes, and earthquakes. The latter confirmations are evidently apparent across current ethnology, cultures, linguistics, religion, rituals, exotic astronomy, somewhat concealed evidence of native record-keeping/writing, and iconography. Use of cultural anthropology while observing a modern Peruvian sacred-site-sweeping at Cuzco, coupled with their assertion that Ñari Huallac means ``serpent God,'' plus electromagnet information, reveals that their religious world-view include(s)(d) applied science that is still otherwise unacknowledged. Alexander Thom's precise megalithic site-measurements also imply that ``The Ancients' Serpent'' made/makes precise tracks that convey valuable information. The linguistics of words like Seminole, and unusual visual effects, reveal some traditionalists have done better than most scientists, for vision, and observational physics, and earth science. Tornado and hurricane tracks are predictable, as are some earthquakes. Tornado ``detuning'' or shutdown is electromagnetically possible.

    Full Text Available Mining of minerals that have significant impact on landscape and landscape functions affects 1% of the land surface worldwide. In the Czech Republic the extent of mining sites is estimated to be more than 800 km2 and according to the state legislation the land affected by mining should be reclaimed. There are several approaches to land restoration, which are shortly reviewed in this article, from pure technical approach to one adopting natural processes. The review shows increasing appeal of scientist and conservationist to use natural processes e.g. natural or directed succession as an alternative method of post-mining sites or industrial deposits restoration due to growing evidence of conservational value of such sites in human dominated landscapes. The natural processes used for land restoration are often argued to be slow therefore the rate of spontaneous vegetation succession was assessed in stone quarries and on spoil heaps using a sequence of panchromatic aerial images. The results showed that natural processes act fast and vegetation can reach 100% cover within 10-15 years in granodiorite quarries and on spoil heaps.

    2008-01-01

    In a letter to the U.S. Geological Survey (USGS) dated March 25, 2008, Representative Jane Harman (California 36th district) requested advice on geologic hazards that should be considered in the review of a proposed liquefied natural gas (LNG) facility off the California coast in Santa Monica Bay. In 2004, the USGS responded to a similar request from Representative Lois Capps, regarding two proposed LNG facilities offshore Ventura County, Calif., with a report summarizing potential geologic and seismic hazards (Ross and others, 2004). The proposed LNG Deepwater Port (DWP) facility includes single point moorings (SPMs) and 35 miles of underwater pipelines. The DWP submersible buoys, manifolds, and risers would be situated on the floor of the southern Santa Monica Basin, in 3,000 feet of water, about 23 miles offshore of the Palos Verdes Peninsula. Twin 24-inch diameter pipelines would extend northeastward from the buoys across the basin floor, up the basin slope and across the continental shelf, skirting north around the Santa Monica submarine canyon. Figure 1 provides locations of the project and geologic features. Acronyms are defined in table 1. This facility is being proposed in a region of known geologic hazards that arise from both the potential for strong earthquakes and geologic processes related to sediment transport and accumulation in the offshore environment. The probability of a damaging earthquake (considered here as magnitude 6.5 or greater) in the next 30 years within about 30 miles (50 km) of the proposed pipeline ranges from 16% at the pipeline's offshore end to 48% where it nears land (Petersen, 2008). Earthquakes of this magnitude are capable of producing strong shaking, surface fault offsets, liquefaction phenomena, landslides, underwater turbidity currents and debris flow avalanches, and tsunamis. As part of the DWP license application for the Woodside Natural Gas proposal in Santa Monica Bay (known as the OceanWay Secure Energy Project), Fugro

    2000-10-01

    The diversity and abundance of native grasses and herbaceous species characteristic of the longleaf savanna were compared between remnant stands that were not previously under agriculture and recent old-fields.The objective of the study was to establish a baseline for future restoration objectives and to compare the degree of degradation associated with agriculture. In most cases even the natural stands have suffered degradation as a result of fire exclusion and as such are not representative of pristine conditions. Community classification and ordination procedures were implemented to array the communities. Three distinct sub-units were identified and associated with xeric, sub-xeric, and medic types associated with texture and soil moisture. Between plantations and natural stands, the xeric group demonstrated the most similarity. The presence of a B horizon was the most important discriminate variable in both groups.

    Investigating competitive adsorption on river/lake sediments is valuable for understanding the fate and transport of heavy metals. Most studies have studied the adsorption isotherms of competitive heavy metals, which mainly comparing the adsorption information on the same concentration. However, intrinsically, the concentration of each heavy metal on competitive adsorption sites is different, while the adsorption energy is identical. Thus, this paper introduced the site energy distribution theory to increase insight into the competitive adsorption of heavy metals (Cu, Cd and Zn). The site energy distributions of each metal with and without other coexisting heavy metals were obtained. It illustrated that site energy distributions provide much more information than adsorption isotherms through screening of the full energy range. The results showed the superior heavy metal in each site energy area and the influence of competitive metals on the site energy distribution of target heavy metal. Site energy distributions can further help in determining the competitive sites and ratios of coexisting metals. In particular, in the high-energy area, which has great environmental significance, the ratios of heavy metals in the competitive adsorption sites obtained for various competitive systems were as follows: slightly more than 3:1 (Cu-Cd), slightly less than 3:1 (Cu-Zn), slightly more than 1:1 (Cd-Zn), and nearly 7:2:2 (Cu-Cd-Zn). The results from this study are helpful to deeply understand competitive adsorption of heavy metals (Cu, Cd, Zn) on sediment. Therefore, this study was effective in presenting a general pattern for future reference in competitive adsorption studies on sediments. Copyright © 2018 Elsevier Ltd. All rights reserved.

    1999-01-01

    The US Department of Energy has undertaken a project to reduce energy expenditures and improve energy system reliability in the 300 Area of the Hanford Site near Richland, Washington. This project replaced the centralized heating system with heating units for individual buildings or groups of buildings, constructed a new natural-gas distribution system to provide a fuel source for many of these units, and constructed a central control building to operate and maintain the system. The individual heating units include steam boilers that are housed in individual annex buildings located in the vicinity of a number of nuclear facilities operated by the Pacific Northwest National Laboratory (PNNL). The described analysis develops the basis for siting the package boilers and natural-gas distribution system used to supply steam to PNNL's 300 Area nuclear facilities. Minimum separation distances that would eliminate or reduce the risks of accidental dispersal of radioactive and hazardous materials in nearby nuclear facilities were calculated based on the effects of four potential fire and explosion (detonation) scenarios involving the boiler and natural-gas distribution system. These minimum separation distances were used to support siting decisions for the boilers and natural-gas pipelines

    Naturally occurring radioactive element can be found in low levels within all rock, soil, and water. The present work aims to understand the transfer of naturally occurring radionuclides in different compartments of environment reflecting its behaviour in different tropic levels. The understanding and evaluation of the possible interactions of various naturally occurring radionuclides were done in the world's third largest man-made dam, Nagarjuna Sagar, built on river Krishna located in Andhra Pradesh, India. The naturally occurring radionuclides such as Uranium ( 238 U), Polonium ( 210 Po), Radium ( 226 Ra), and Lead ( 210 Pb) were analyzed in different matrices (i.e) sediment, water, and fish. The measurement of the naturally occurring radionuclides in the environment can be used as a reference baseline for long-term monitoring in the entire aquatic ecosystem

    The results indicate that the meaning of profane and sacred can be revealed through the description of liz‘s process in searching her existence. It can be seen in the novel‘s text through it‘s main signifier as represented by two words ‖big house‖ and ‖bath room‖. ‖Big house‖ symbolizes happiness, peace, and power; meanwhile ‖bath room‖ symbolizes sadness and loneliness. Liz, who is supposed to be comfortable living in happiness finally decides to negate it. Instead of enjoying her wonderful life represented by wealth, marriage, and family, Liz prefers to become nomadic, divorce her husband, and have no children. The process of searching her existence then leads her into spiritual experience that can be broken down into two binary oppositions: profane and sacred. She sacralizes the profane activities such as crying in the bath room, contemplating, scrubing the temple floors, and experiencing metaphysical crisis, to reach the God.

  20. Primitive Rituals, Contemporary Aftershocks: Evocations of the Orientalist ‘Other’ in four productions of 'Le Sacre du printemps'

    Directory of Open Access Journals (Sweden)

    Lucy Weir

    2013-12-01

    Full Text Available This paper situates the original choreography of Sacre as a basis for an ongoing exploration of non-Western themes in modern dance, a persistent fascination with the Orientalist ‘Other,’ before exploring the versions choreographed by Wigman, Bausch and Graham in chronological order of their first performances. In analysing different interpretations of the same score, two themes become apparent: first, that this piece heralded the birth of Modernism in classical dance performance, and second, that the driving anti-classical, anti-traditional rhythms that characterise the piece communicate an enduring interest in primitive aesthetics. Accordingly, this discussion takes Nijinsky’s Sacre as a starting point in re-evaluating the influence of primitivism and Otherness on contemporary dance, and represents an early indication of the significance of the Saidian, non-Western ‘Other’ in shaping the evolution of avant-garde dance.

    Contamination of soils with tar oil occurred on many industrial sites in Europe. The main source of such contamination has been former manufactured gas plants (MGP). As many of them were destroyed during the World War II or abandoned in the second half of the XXth century, the contamination is depleted in volatile and degradable hydrocarbons (HC) but enriched in the heavy oil fractions due to aging processes. We studied a small tar-oil spill in a former MGP reservoir basin. The tar-oil had a total petroleum hydrocarbon (TPH) content of 245 mg/g. At the margin of the spill, vegetation has started to overgrow and intensively root the tar-oil layer. This zone comprised the uppermost 5-7 cm of our profile and contained 28 mg/g of TPH (A-layer)- The layer below the root zone (7-15 cm) was the most contaminated, with 90 mg/g TPH (B-layer). The layer underneath (15-22 cm) had smaller concentrations of 16 mg/g TPH (C-layer). Further down in the profile (D-layer) we found only slightly higher TPH content than in the control samples (1,4 mg/g vs 0,6 mg/g). The polycyclic aromatic hydrocarbons analysis showed the same distribution throughout all layers with highest contents of the PAHs with 4-6 condensed aromatic rings. Direct cell count and extraction of microbial biomass showed that the highly contaminated soil layers A and B had 2-3 times more bacteria than the control soils. CARD-FISH analysis revealed that in samples from layers A and B Archaea were more abundant (12% opposing to 6-7% in control soil). Analysis of bacteria (tested for Alpha-, Beta-, Gamma- and Epsilonproteobacteria and Actinobacteria) showed the dominance of Alphaproteobacteria in the layer A and C both beneath and above the most contaminated layer B. The primers covered the whole microbial consortia in these two layers, leaving almost no unidentified cells. In the most contaminated layer B Alphaproteobacteria amounted only to 20% of the microbial consortium, and almost 40% of the cells remained

    Full Text Available Conventional managed forests and sacred groves are seldom assessed to determine their effectiveness in biodiversity conservation strategies. This study investigated tree and insect diversity in Jachie sacred grove (JSG and Nkrabea forest reserve (NFR in Ashanti region, Ghana. The study area constituted eight plots of 50 × 50 m along two 300 m long transects. Insects were sampled in eight pitfall traps, diagonally between the transects. Out of 150 individuals, 13 species in NFR and 15 species from JSG were registered. Celtis mildbraedii was the most dominant species in NFR = 43.18% and JSG = 23.58%. Mean DBH showed a significant relationship with basal area in NFR and JSG. Tree diversity and richness were higher in JSG (H′ = 1.43–2.3 ± 0.10; D = 1.8–3.69 ± 0.30 compared to NFR (H′ = 0.86–1.56 ± 0.09; D = 1.1–2.3 ± 0.57. However, insect diversity was higher in NFR (H′ = 1.34 ± 0.10 than in JSG (H′ = 0.5 ± 0.005. Camponotus furvus and Pachycondyla tarsata were most abundant in JSG and NFR, respectively. These findings will help conservationists work closely with traditional authorities in protecting sacred groves as key biodiversity hotspots.

    Crossing boundaries of faith from Manila to Jakarta, this study is to classify the open spaces in their sacred grounds according to its characteristics, elements, use of space and hierarchy of importance in landscape design approach. The reflection of their religious landscape in preserving the traditional, and exploring the non-traditional aspect of their landscape design in global setting is carried out thru a spatial analysis for Plaza de Roma of Manila Cathedral and the sacred grounds of Istiqlal Mosque. The design framework would tackle: concepts, planning approach, functional symbolic values, and aesthetics used. The data and information are all examined based on observation, historical background, analyses, and literature content in determining spatial functions. Finally, when results are completed, this will give a better understanding on the importance of open areas in Manila and Jakarta’s sacred spaces; paving way for a better sense of comfort in spiritual contemplation. This will also help reveal the commonalities in spiritual practices between Islam and Christianity, and the role of landscape in their religion and faith.

They generally agree on where surfing initially developed, that it assumed a religious character, was suppressed for religious reasons, has been undergoing a revival, and enjoins reverence for and protection of nature. This subset of the global surfing community should be understood as a new religious movement-a globalizing, hybridized, and increasingly influential example of what I call aquatic nature religion. For these individuals, surfing is a religious form in which a specific sensual practice constitutes its sacred center, and the corresponding experiences are constructed in a way that leads to a belief in nature as powerful, transformative, healing, and sacred. I advance this argument by analyzing these experiences, as well as the myths, rites, symbols, terminology, technology, material culture, and ethical mores that are found within surfing subcultures.

    Mining of minerals that have significant impact on landscape and landscape functions affects 1% of the land surface worldwide. In the Czech Republic the extent of mining sites is estimated to be more than 800 km2 and according to the state legislation the land affected by mining should be reclaimed. There are several approaches to land restoration, which are shortly reviewed in this article, from pure technical approach to one adopting natural processes. The review shows increasing appeal of ...

  12. Frameworks for Understanding the Nature of Interactions, Networking, and Community in a Social Networking Site for Academic Practice

    Full Text Available This paper describes a new social networking site, Cloudworks, which has been developed to enable discussion and sharing of learning and teaching ideas/designs and to promote reflective academic practice. The site aims to foster new forms of social and participatory practices (peer critiquing, sharing, user-generated content, aggregation, and personalisation within an educational context. One of the key challenges in the development of the site has been to understand the user interactions and the changing patterns of user behaviour as it evolves. The paper explores the extent to which four frameworks that have been used in researching networked learning contexts can provide insights into the patterns of user behaviour that we see in Cloudworks. The paper considers this within the current debate about the new types of interactions, networking, and community being observed as users adapt to and appropriate new technologies.

  13. About the nature of regional thermal anomaly in the Semipalatinsk Test Site region revealed basing on remote space sensing data

    2003-01-01

    A thermal anomaly, (more than 20,000 sq. km) discovered in the Semipalatinsk Test Site region in the pictures from space, is observed every year on certain days mainly in winter-spring season. Appearance of the thermal anomaly often coincides with days of intensive fall of atmospheric precipitation and possible thawing of snow cover together with decreasing of ozone concentration in atmosphere. The explanation of thermal anomaly in the Semipalatinsk Test Site region due to nuclear reaction caused by the energy of radionuclide radioactive decay deposited in a soil layer after ground and air nuclear explosions and radiolysis processes in soil solutions is given in this article.

  14. The dependence of natural regeneration of forest trees on upper soil conditions and acidity at damaged sites in the Black Forest, Germany

    1993-06-01

    It was the goal of this study to investigate the influence of different upper soil conditions on the germination and establishment, as well as the growth, of young plants of various tree species. For this purpose, four test plots in the region of the Black Forest were laid out, in which, by various means of site preparation and fertilization, the upper soils were changed. Natural seeding of common spruce, European silver-fir, beech, sycamore maple, European mountainash, and grey alder was simulated by means of controlled sowing. For comparison, a greenhouse experiment was carried out, examining the germination and development of the same tree species in various soil substrata, using different fertilizers, and under the influence of artificial acid rain. The most important results - with a high level of variation depending on the tree species examined - can be summarized as follows: Based on the results of field and greenhouse experiments, as well as on the investigations of other authors, it can be concluded that natural regeneration of forest stands is considerably impeded under conditions of increasing soil acidity and by high acid depositions. This is seen directly as the result of unfavorable chemical conditions in the upper soil, as well as indirectly due to deteriorating competitiveness against other vegetation. Site preparation and lime or dolomite fertilization can be important measures in the practice of forestry, to encourage natural regeneration in highly acidic sites with an unfavourable humus layer and a high presence of competing vegetation.

    1997-01-01

    The natural fission reactors of Oklo consists of a core of uraninite (60%) with fission products, embedded in a pure clay matrix. Thus, the aim of geological, mineral, and geochemical studies of the Oklo Reactors is to assess the behaviour of fission products in an artificial waste depository. Previous studies have shown that Reactor Zone 10, located in the Oklo mine, represents an example for an exceptional confinement of fission products since 2 Ga. In reactor Zone 9, located in Oklo open pit, migrations are more important. Reactor ZOne 13 was influenced by a thermal event due to a doleritic intrusion, located some twenty meters far away, one Ga years after fission reaction operations. In this study,we characterized temperature and redox conditions of fluids by using stable isotopes of uraninites and clays. Moreover mineralogical and chemical characteristics were defined. (author)

  16. Environmental assessment for the natural fluctuation of water level in Par Pond and reduced water flow in Steel Creek below L-Lake at the Savannah River Site

    1995-08-01

    The Savannah River Operations Office Strategic Plan directs Savannah River Site (SRS) to find ways to reduce operating costs, and to determine what site infrastructure must be maintained and what infrastructure is surplus. Because of the mission change, L-Lake, Par Pond, and the river water system are no longer needed to support current missions and therefore provide an opportunity for operating cost reduction. If SRS determines that L-Lake, Par Pond, and the river water system are no longer needed to support future missions and are considered surplus, appropriate NEPA documentation will be prepared. The purpose of the proposed action in this Environmental Assessment is to begin an examination of the need for the Site`s river water system by (1) developing data needed to evaluate the potential environmental impacts of further reducing or eliminating the flow demands from the Site`s river water system and; (2) evaluating the potential of reducing operating costs by allowing the water level in Par Pond to fluctuate naturally through reduced pumping. This action also includes reducing the current flow rates from L-Lake to Steel Creek to natural stream flows while maintaining full pool. The recently approved Par Pond CERCLA Interim Action Proposed Plan (IAPP) committed to evaluate in a NEPA document the environmental consequences of this proposed action. This document evaluated the remediation of human health and ecological risks associated with the three year drawdown of Par Pond. Should any of the parameters sampled in the reservoir and streams (e.g., water quality, biota, etc.) exceed established threshold levels during the implementation of the proposed action, water would again be pumped into the reservoir to minimize any impacts by bringing the water level back to an appropriate level about 58.2 m (195 ft).

  17. Consequences of least tern (Sternula antillarum) microhabitat nest-site selection on natural and mechanically constructed sandbars in the Missouri River

    Nest-habitat selection in colonial species has rarely been assessed at multiple spatial scales to evaluate its fitness consequences. Management for the federally endangered U.S. Interior population of Least Terns (Sternula antillarum) has focused on maintenance of breeding habitats, including mechanical construction of sandbars from dredged material. Least Terns are attracted to large areas of unvegetated substrate, yet small-scale habitat features are thought to trigger selection for nesting. We evaluated nest-scale habitat selection to determine (1) whether selection differs between constructed and natural sandbars and (2) the subsequent consequences of habitat selection on nest success. During 2006–2008, we examined 869 Least Tern nest sites on constructed and natural sandbars in the Missouri River for evidence of microhabitat selection at the nest in relation to habitat within the surrounding 3-m area. Least Tern nest sites had coarser and larger substrate materials at the nest, more debris, and less vegetation than the surrounding area. Nests in constructed habitats had a greater percentage of coarse substrates and less vegetation or debris than nests in naturally created habitats. Apparent nest success was 1.8× greater on constructed than on natural sandbars. Nest success was best predicted by models with two spatial scales of predictors, including substrates (nest) and vegetation and debris (nest or surrounding area). Our results indicate that Least Terns select nest microhabitat characteristics that are associated with wind- and water-scoured habitats, and that nest success increases when these habitats are selected.

  18. The Effects of Sacred Value Networks Within an Evolutionary, Adversarial Game

    2013-05-01

    The effects of personal relationships and shared ideologies on levels of crime and the formation of criminal coalitions are studied within the context of an adversarial, evolutionary game first introduced in Short et al. (Phys. Rev. E 82:066114, 2010). Here, we interpret these relationships as connections on a graph of N players. These connections are then used in a variety of ways to define each player's "sacred value network"—groups of individuals that are subject to special consideration or treatment by that player. We explore the effects on the dynamics of the system that these networks introduce, through various forms of protection from both victimization and punishment. Under local protection, these networks introduce a new fixed point within the game dynamics, which we find through a continuum approximation of the discrete game. Under more complicated, extended protection, we numerically observe the emergence of criminal coalitions, or "gangs". We also find that a high-crime steady state is much more frequent in the context of extended protection networks, in both the case of Erdős-Rényi and small world random graphs.

  19. Politics, religion and space. About places of mediation and sacred space among the Gurage of Ethiopia

    Directory of Open Access Journals (Sweden)

    PALMISANO, Antonio Luigi

    2016-12-01

    Full Text Available The main faiths among the Gurage of Ethiopia – Orthodox Christianity, Islam and autochthonous polytheism – provide a constellation of integrative principles for territorial and descent segmentation. Religious leaders and ritual specialists of the three confessions have always represented the unity of Gurage tribes facing the outside world and still receive tributes of cattle, sheep, goats, honey, ensete, money etc. The ethnic court of justice of the Gurage, the yejoka, has re-dimensioned its office, in order to prevent the rise of central instances within the process of political mediation between juxtaposed lineages and territorial segments. The article focuses on the identification and institutionalisation of sacred places among these tribes, the places where the personae, the lineages and residential groups interact within the self-representation processes of Gurage society. The theological and liturgical pluralism, practised by the three faiths, confirms the Gurage’s capacity to answer to the many and contradictory stimuli of modern society, of market economy, of political, administrative and territorial transformation which takes place in the world. This religious plurality in a single family, in a single person, unveils religion as an answer, or rather as a structure of satisfactory answers.

  20. POETICS OF TRANSCENDENCE: STYLISTIC REDUCTION AS A TOOL FOR REPRESENTATION OF SACRED MEANINGS

    2016-10-01

    Full Text Available The main direction of the work is connected to the representation of abstract (transcendent objects in music and literature. The article analyses "Cantus in Memoriam Benjamin Britten" by Arvo Pärt and some poems of Czesław Miłosz. The metaphysical dimension of reality involves forms and things, existing beyond the boundaries of empirical perception and, at first sight, beyond the descriptive practices. Abstract objects are available in intellectual experience, but culture must transform them into a symbolic form. As a rule, it is connected to the practice of art minimalism. The essence of minimalism is the reduction of number of stylistic tools and “purification” the perception from the visual / auditory images (not a mimetic use of language. For the representation of the sacred Pärt uses only mensural canon form, scale and chord. These “characters” are deprived of descriptive function, but have symbolic potential (canon as a sign of stopped time, the eternal return. The distinctive feature of the Miłoszʼs style is the pursuit to “clean” the signs (indexical and symbolic. There is the reverse side of language distillation: the rejection of the subjective position, emotional experience, the distance between the person and the object of representation.

    A geological and geomorphological analysis has been performed in the necropolis of Dra Abu el-Naga in order to understand the role played by these two factors in the development of the sacred landscape. The investigation focuses upon two aspects of the development of the necropolis, the selection criteria for tomb location and the reconstruction of the ancient funerary landscape. Around 50 tombs were surveyed, analysing the characteristics of their host rock and classifying them according to a modified Rock Mass Rating Index, in order to understand how rock quality affected tomb construction. This analysis resulted in the definition of five rock-quality classes (I to V) from very good to very poor rock. The geological study also resulted in a proposed geological-geomorphological model for the evolution of this zone of the Theban necropolis that complements previous works by other authors. Due to the lack of precise dating evidence this chronology is a relative one and is based on the chronology given by other authors for similar deposits and events. Two catastrophic events, represented by mega-landslides, have been identified, the first one predates the deposition of early Pleistocene fluvial deposits, and the second one possibly occurred during the middle-late Pleistocene. Two weathering surfaces developed under wetter than present climatic conditions and have been tentatively correlated to the mid-late Pleistocene humid period and the African-Humid Period (early-mid Holocene).

    The fields of palliative and holistic nursing both maintain a commitment to the care of the whole person, including a focus on spiritual care. Advanced serious illness may pose a plethora of challenges to patients seeking to create meaning and purpose in their lives. The purpose of this article is to introduce scholarly dialogue on the integration of entheogens, medicines that engender an experience of the sacred, into the spiritual and holistic care of patients experiencing advanced serious illness. A brief history of the global use of entheogens as well as a case study are provided. Clinical trials show impressive preliminary findings regarding the healing potential of these medicinal agents. While other professions, such as psychology, pharmacy, and medicine, are disseminating data related to patient outcomes secondary to entheogen administration, the nursing literature has not been involved in raising awareness of such advancements. Research is illustrating their effectiveness in achieving integrative experiences for patients confronting advanced serious illness and their ability to promote presence, introspection, decreased fear, and increased joy and acceptance. Evidence-based knowledge surrounding this potentially sensitive topic is necessary to invite understanding, promote scientific knowledge development, and create healing environments for patients, nurses, and researchers alike.

    Full Text Available The paper examines the main reasons for the emergence and spread of Quebec swearing (les sacres. Socio-psychological aspects of their origin and distribution in the Quebec dialect of the French language are analyzed. It is established that after the Silent Revolution (Révolution tranquille of the 6070s of the 20th century, the influence of the Catholic Church in Quebec was minimized, so the “les sacres” lost their original meaning and no longer bear a religious connotation. Various variants of classification of mechanisms of word-formation “les sacres” are also given in the work. Separately, the classification proposed by André Bugaev has been singled out, within the framework of which the mechanisms of the word-formation “les sacres” are discussed in detail. With its use, it is suggested to perform a linguistic analysis of the retrospective of the word-formation system “les sacres” and to establish a relationship with socio-political factors.

    Many sites used during the early days of the US atomic energy program are contaminated with radionuclides of the primordial decay chains (uranium, thorium, and actinium series). This contamination consists of residues resulting from refining and processing uranium and thorium. Preparation of these sites for release to unrestricted private use will involve the assistance of construction workers, many of whom have limited knowledge of the hazards associated with radioactive materials. Therefore, there is a need to educate these workers in the fundamentals of radioactive material handling to minimize exposures and possible spread of contamination. This training should disseminate relevant information at an appropriate educational level and should instill a cautious, common-sense attitude toward the handling of radioactive materials. The training should emphasize basic information concerning environmental radiation within a context of relative risk. A multi-media format, including colorful visual aids, demonstration, and discussion, should be used to maximize motivation and retention. A detailed, proposed training program design is presented

  6. Naturally occurring deletions of hunchback binding sites in the even-skipped stripe 3+7 enhancer.

    Arnar Palsson

    Full Text Available Changes in regulatory DNA contribute to phenotypic differences within and between taxa. Comparative studies show that many transcription factor binding sites (TFBS are conserved between species whereas functional studies reveal that some mutations segregating within species alter TFBS function. Consistently, in this analysis of 13 regulatory elements in Drosophila melanogaster populations, single base and insertion/deletion polymorphism are rare in characterized regulatory elements. Experimentally defined TFBS are nearly devoid of segregating mutations and, as has been shown before, are quite conserved. For instance 8 of 11 Hunchback binding sites in the stripe 3+7 enhancer of even-skipped are conserved between D. melanogaster and Drosophila virilis. Oddly, we found a 72 bp deletion that removes one of these binding sites (Hb8, segregating within D. melanogaster. Furthermore, a 45 bp deletion polymorphism in the spacer between the stripe 3+7 and stripe 2 enhancers, removes another predicted Hunchback site. These two deletions are separated by ∼250 bp, sit on distinct haplotypes, and segregate at appreciable frequency. The Hb8Δ is at 5 to 35% frequency in the new world, but also shows cosmopolitan distribution. There is depletion of sequence variation on the Hb8Δ-carrying haplotype. Quantitative genetic tests indicate that Hb8Δ affects developmental time, but not viability of offspring. The Eve expression pattern differs between inbred lines, but the stripe 3 and 7 boundaries seem unaffected by Hb8Δ. The data reveal segregating variation in regulatory elements, which may reflect evolutionary turnover of characterized TFBS due to drift or co-evolution.

    1983-03-01

    The economic potentials of several alternative land uses at the Nevada Test Site (NTS) are estimated. Alternatives considered include mining, agriculture, grazing, and hunting. There are two known tungsten ore bodies located in the Oak Spring mining district. The economic potential of the reserves is estimated to be $42,840. It is also possible that there are other economic mineral resources on the NTS whose values are yet unknown. There are an estimated 5000 ha of agricultural land on the Test Site; the cash value of alfalfa grown on this acreage is approximately $564,030. The economic potential of grazing at the Test Site lies somewhere in the range of $10,340 to $41,220. The assumed annual worth of mule deer to hunters is $90,440. The gross potential of hunting at the NTS is probably somewhat higher if trophy species, game birds and fur-bearing animals are also considered. It should be noted that the above values indicate gross worth; no costs are included in the estimates

    This report describes the results of sorption experiments designed to provide essential data for migration modelling. Sorption of 233 U from natural ground-water onto peat from Broubster and silt from Needle's Eye was studied under atmospheric conditions and different pH regimes. The temperature was maintained at 10 0 C and, in the case of Needle's Eye silt, the kinetics of sorption were followed. The results were analyzed in conjunction with speciation modelling in an attempt to understand the sorption mechanisms and to extrapolate the findings to cover the range of conditions likely to be met in the field.

    Water-quality, aquifer-sediment, and hydro-logic data were used to assess the effectiveness of natural attenuation of ground-water contamination at Fire Training Area Three, the Rubble Area Landfill, the Liquid Waste Disposal Landfill, and the Receiver Station Landfill in the East Management Unit of Dover Air Force Base, Delaware. These sites, which are contaminated with chlorinated solvents and fuel hydrocarbons, are under-going long-term monitoring to determine if natural attenuation continues to sufficiently reduce contaminant concentrations to meet regulatory requirements. This report is the first assessment of the effectiveness of natural attenuation at these sites since long-term monitoring began in 1999, and follows a preliminary investigation done in 1995?96. This assessment was done by the U.S. Geological Survey in cooperation with the U.S. Air Force.Since 1995?96, additional information has been collected and used in the current assessment. The conclusions in this report are based primarily on ground-water samples collected from January through March 2000. Previous analytical results from selected wells, available geologic and geo-physical well logs, and newly acquired information such as sediment organic-carbon measurements, hydraulic-conductivity measurements determined from slug tests on wells in the natural attenuation study area, and water-level measurements from surficial-aquifer wells also were used in this assessment. This information was used to: (1) calculate retardation factors and estimate contaminant migration velocities, (2) improve estimates of ground-water flow directions and inferred contaminant migration pathways, (3) better define the areal extent of contamination and the proximity of contaminants to discharge areas and the Base boundary, (4) develop a better under-standing of the vertical variability of contaminant concentrations and redox conditions, (5) evaluate the effects of temporal changes on concentrations in the plumes and

    This report summarizes the result on selecting sites for large-caliber production wells, and landscape characteristic evaluation for simulation, based on the landscape survey on C candidate site for geothermal development. Field survey was made on landscape, plants and animals in the Kirishima Eboshidake area. It was clarified that this area has diverse flora including some rare species such as rein orchid and monkshood which are listed as endangered species. In addition, not a few epiphytes were identified. The zoological survey result showed that planted forests of evergreen coniferous trees which cover a wide range of the surveyed area, and peripheral grassland, scrub and natural forests provide good habitats for mammals such as sika deer and wild boars. On the other hand, no animal species in need of special protection were found. Geologically some traces of landslide occurrence in the past were detected in the northern part of the surveyed area relatively. As the survey result, some promising sites suitable for geothermal development were selected, which are judged to have a relatively small impact on natural environment and landscape. (NEDO)

    The main focus of this report is to develop and test a methodology for performing large simulations of transient variable density flow. Several developments were made to NAMMU to enable such calculations. The following lists the findings of this study: 1) Feasibility: it is numerically feasible to construct large (0.5 million elements) embedded models of transient variable density flow with a relatively fine mesh (about 35m) of the site-scale. 2) Stochastic simulation: performing stochastic realisations of long transients is just possible, although the requirements on CPU and disk to store the results for 100 realisations, say, would be significant. As an indication, about 19 realisations of the current model could be run on a Sun Enterprise 450 (4 x UltraSPARC-II 400MHz) computer in one week if all four processors are fully utilised. 3) Embedded grid: the nesting of a refined site-scale model (35m elements) within a coarser (100m) regional-scale mesh for variable density flow was tested successfully. It was found that grading the refinement around the site-scale to avoid a large step change in element size was beneficial for convergence and stability. This may be less of an issue if a more sophisticated pre conditioner was used. 4) Solver: the most efficient and stable scheme was obtained by decoupling the flow and transport equation at each time-step. GMRES (Generalised Minimum Residual) was the most robust conjugate gradient method for this problem. 5) Boundary conditions: a set of relatively complex non-linear boundary conditions had to be applied for both pressure and salinity on the top and vertical boundaries to give the system sufficient freedom to approximate realistic conditions over a large area and long times. It was important that both flow and a flux of salinity could cross each boundary, and that the direction and magnitude could evolve in time. 6) Calibration on salinity: model predictions of the salinity in the deep boreholes were used to calibrate

    In order to determine the correlations between the following atmospheric parameters: radon and condensation nuclei concentrations, total conductivity and space charge, we analysed their behavior over a long period, in connection with meteorological data. We simulaneously studied the equilibrium state between 222 Rn and its short-lived daughters pointing out a radioactive desequilibrium as a function of the meteorological conditions. Simultaneously, we established average experimental curves of cumulated particle size distributions of natural radioactivity in the air, differentiating urban and marine influences. Finally, a comparison between the various parameters showed that the total conductivity greatly depends on condensation nuclei and radon concentrations in the air [fr

    We investigated the influence of tree species on the natural 15N abundance in forest stands under elevated ambient N deposition.We analysed δ15N in litter, the forest floor and three mineral soil horizons along with ecosystem N status variables at six sites planted three decades ago with five Eur...... to nitrate leaching or other N transformation processes....... species leached more nitrate.The δ15N pattern reflected tree species related traits affecting the N cycling as well as site fertility and former land use, and possibly differences in N leaching. The tree species δ15N patterns reflected fractionation caused by uptake of N through mycorrhiza rather than due...

  16. A sacred command of reason? Deceit, deception, and dishonesty in nurse education.

    Kant (Grounding for the Metaphysics of Morals. Hackett, Indianapolis, 1797) described honesty as 'a sacred command of reason' which should be obeyed at all times and at any cost. This study inquires into the practice of dishonesty, deception, and deceit by universities in the UK in the pursuit of quality indicators such as league table positions, Research Excellence Framework (REF) scores, and student satisfaction survey results. Deception occurs when the metrics which inform these tables and surveys are manipulated to suggest an improvement in quality when, in fact, the raised scores are merely the result of clever strategic planning. Deceit occurs when these manipulated scores are deliberately and knowingly presented as real improvements in research and educational quality. It might be argued that, within the context of the artificial ivory tower world of academe, this is a game played by almost every academic in every higher education institution with no real losers and little wider consequence. However, this study suggests that some of the strategies employed by institutions to improve their scores without directly addressing the issue of quality can, in certain practice-based disciplines such as nursing, result in dire consequences for practitioners and service users. It concludes with a number of suggestions taken from personal experience to resolve the tension between the contractual demands placed on nurse academics by their employers and the moral and practical obligations of their professional body, most notably the use of subversion. The conclusion, contra Kant, is that the most effective strategy against dishonesty and deception is often more dishonesty and deception. © 2016 John Wiley & Sons Ltd.

    This paper proposed a new concept of ecological security for protection by a comprehensive analysis of the contents and standards of world heritage sites. A frame concept model named "Pressure-State-Control" for early warning of ecological security at world heritage mixed sites was constructed and evaluation indicators of this frame were also selected. Wuyishan Scenery District was chosen for a case study, which has been severely disturbed by natural and artificial factors. Based on the frame model of "Pressure-State-Control" and by employing extension analysis, the matter-element model was established to assess the ecological security status of this cultural and natural world heritage mixed site. The results showed that the accuracy of ecological security early warning reached 84%. Early warning rank was I level (no alert status) in 1997 and 2009, but that in 2009 had a higher possibility to convert into II level. Likewise, the early-warning indices of sensitive ranks were different between 1997 and 2009. Population density, population growth rate, area index for tea garden, cultivated land owned per capita, level of drought, and investment for ecological and environmental construction were the main limiting factors to hinder the development of ecological security from 2009 to future. In general, the status of Wuyishan Scenery District ecological security was relatively good and considered as no alert level, while risk conditions also existed in terms of a few early-warning indicators. We still need to pay more attention to serious alert indicators and adopt effective prevention and control measures to maintain a good ecological security status of this heritage site.

    In 1994, the Pacific Northwest Laboratory (PNL) initiated the Recharge Task, under the PNL Vitrification Technology Development (PVTD) project, to assist Westinghouse Hanford Company (WHC) in designing and assessing the performance of a low-level waste (LLW) disposal facility for the US Department of Energy (DOE). The Recharge Task was established to address the issue of ground water recharge in and around the LLW facility and throughout the Hanford Site as it affects the unconfined aquifer under the facility. The objectives of this report are to summarize the current knowledge of natural ground water recharge at the Hanford Site and to outline the work that must be completed in order to provide defensible estimates of recharge for use in the performance assessment of this LLW disposal facility. Recharge studies at the Hanford Site indicate that recharge rates are highly variable, ranging from nearly zero to greater than 100 mm/yr depending on precipitation, vegetative cover, and soil types. Coarse-textured soils without plants yielded the greatest recharge. Finer-textured soils, with or without plants, yielded the least. Lysimeters provided accurate, short-term measurements of recharge as well as water-balance data for the soil-atmosphere interface and root zone. Tracers provided estimates of longer-term average recharge rates in undisturbed settings. Numerical models demonstrated the sensitivity of recharge rates to different processes and forecast recharge rates for different conditions. All of these tools (lysimetry, tracers, and numerical models) are considered vital to the development of defensible estimates of natural ground water recharge rates for the performance assessment of a LLW disposal facility at the Hanford Site

  19. Environmental assessment for the natural fluctuation of water level in Par Pond and reduced water flow in Steel Creek below L-Lake at the Savannah River Site

    International Nuclear Information System (INIS)

    1995-08-01

    The Savannah River Operations Office Strategic Plan directs Savannah River Site (SRS) to find ways to reduce operating costs, and to determine what site infrastructure must be maintained and what infrastructure is surplus. Because of the mission change, L-Lake, Par Pond, and the river water system are no longer needed to support current missions and therefore provide an opportunity for operating cost reduction. If SRS determines that L-Lake, Par Pond, and the river water system are no longer needed to support future missions and are considered surplus, appropriate NEPA documentation will be prepared. The purpose of the proposed action in this Environmental Assessment is to begin an examination of the need for the Site's river water system by (1) developing data needed to evaluate the potential environmental impacts of further reducing or eliminating the flow demands from the Site's river water system and; (2) evaluating the potential of reducing operating costs by allowing the water level in Par Pond to fluctuate naturally through reduced pumping. This action also includes reducing the current flow rates from L-Lake to Steel Creek to natural stream flows while maintaining full pool. The recently approved Par Pond CERCLA Interim Action Proposed Plan (IAPP) committed to evaluate in a NEPA document the environmental consequences of this proposed action. This document evaluated the remediation of human health and ecological risks associated with the three year drawdown of Par Pond. Should any of the parameters sampled in the reservoir and streams (e.g., water quality, biota, etc.) exceed established threshold levels during the implementation of the proposed action, water would again be pumped into the reservoir to minimize any impacts by bringing the water level back to an appropriate level about 58.2 m (195 ft)

    Full Text Available Considering that tourism is one of the World’s largest industry, inter and intra-regional competition is unavoidable. The competition has been further worsened by the globalization nature of tourism. As such, tourism business is better realized when efforts are put towards destination as opposed to regional or national tourism promotion. Against this background, developing and making the ecotourism business plan operational will not only unlock the tourism potential but also help in the management, promotion and protection of the sites for future generations and enhance economic growth of Siaya County in Kenya. In the development of this business plan, a participatory approach was adopted. The participation involved stakeholders; namely Community based organizations (CBOs, boat operators, beach leaders, religious leaders, Kenya Forest Research Institute (KEFRI, operators of hospitality services in the region, local community representatives as well as Provincial administration. The stakeholders were put in a workshop setting which was facilitated by four consultants from Bondo University. The plan also used secondary information sources from Kenya Wildlife Service (KWS, and web sites among others.

    Heathgate has demonstrated the effect of natural attenuation (NA) in post in-situ recovery (ISR) aquifer regions during the operation of the Beverley mine since 2001. Enhanced natural attenuation (ENA) has been considered as the key component of the mine closure concept for the new Beverley Four Mile (BFM) project, complemented by an extensive monitoring program. Data from batch and column tests for BFM core samples was used to calibrate a reactive transport model, whose application in conjunction with the hydrological modelling of the BFM aquifer has shown that NA will result in the restoration of the aquifer in time. ENA within a staged mine development program under the site-specific circumstances is discussed. (author)

    1999-01-01

    A bioremediation system developed by Calgary-based Unique Oilfield Technology Services (UNOTEC) that uses naturally occurring bacteria and fungi to decompose oilfield waste is described. In essence, UNOTEC creates a suitable work environment for microorganisms by mixing drilling residue with organic oil absorbent and bulking agent, and the micro-organisms do the rest. The key ingredient in the mix is canola meal which has been shown to have the ability to immobilize oil and prevent leaching in the containment mixtures following land treatment, due to its oleophilic qualities, which are a function of its origin as an oil seed. Canola meal contains large amounts of protein, hence it is an important source of nitrogen. Since nitrogen is considered essential for stimulating growth in microorganisms, the meal plays a critical role as a catalyst for microbial activity in the containment mix. Details of applying the technology, and on-going experiments demonstrating its efficiency are described. 10 photos

    Full Text Available The archaeological record supports the general proposition that the simplest form of architecture, the round building type, variously persisted throughout the Aegean prehistory. This paper makes a case for the identification of round building as a distinct genre of sacred space in the Aegean Bronze Age, Mycenaean Crete in particular, combining evidence from architecture, iconography and the scripts. Certain archetypical features are thus delineated. It is argued that the historical understanding of the emerging LBA state requires a study of the architecture prior to the 2nd millennium BC as much as other relevant evidence issuing from the latest Aegean strata.

    The Nopal I uranium (U) deposit, Pena Blanca, Mexico is a source term and contaminant transport natural analog to the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. In an attempt to characterize the mobilization and potential transport of radionuclides in the unsaturated zone at the Nopal I deposit, vegetation growing on ore piles was analyzed for {sup 238}U, {sup 235}U, and {sup 232}Th decay-series isotopes. Specimens of Phacelia robusta growing on high-grade piles of U ore were collected and analyzed by alpha autoradiography, and by alpha and gamma spectrometry. Activities for U, thorium (Th), and radium (Ra) isotopes (Bq/kg dried plant) were 300, 1,000, and 7,000 for {sup 238}U, {sup 230}Th, and {sup 226}Ra, respectively. The {sup 226}Ra activities in these specimens are among the highest ever measured for plants; furthermore, the plant-to-soil {sup 226}Ra concentration ratio is higher than expected. These results demonstrate the large mobility and bio-availability of Ra in the Nopal I environment, and support previous indications of recent loss of {sup 226}Ra from the ore body. Comparison between the activities of {sup 238}U and {sup 232}Th decay-chain Th isotopes in the plants and in the ore substrate indicate that relative mobilization into pore solutions of {sup 228}Th > {sup 230}Th > {sup 232}Th, in a ratio of about 50--25:4:1, respectively. The similarity of the plant's {sup 234}U/{sup 238}U activity ratio ({approximately}1.2) to that of a caliche deposit that formed adjacent to the Nopal ore body around 54 ka suggests the {sup 234}U/{sup 238}U activity ratio of U released from the ore is approximately 1.2. The U and {sup 226}Ra isotope activities of the plants and ore substrate, and solubility considerations, are used to assess a source term model of the potential Yucca Mountain repository. These results suggest the use of a natural analog source term model in performance assessments may be non-conservative.

    In a natural analog study of risks associated with carbon sequestration, impacts of CO{sub 2} on shallow groundwater quality have been measured in a sandstone aquifer in New Mexico, USA. Despite relatively high levels of dissolved CO{sub 2}, originating from depth and producing geysering at one well, pH depression and consequent trace element mobility are relatively minor effects due to the buffering capacity of the aquifer. However, local contamination due to influx of saline waters in a subset of wells is significant. Geochemical modeling of major ion concentrations suggests that high alkalinity and carbonate mineral dissolution buffers pH changes due to CO{sub 2} influx. Analysis oftrends in dissolved trace elements, chloride, and CO2 reveal no evidence of in-situ trace element mobilization. There is clear evidence, however, that As, U, and Pb are locally co-transported into the aquifer with CO{sub 2}-rich saline water. This study illustrates the role that local geochemical conditions will play in determining the effectiveness of monitoring strategies for CO{sub 2} leakage. For example, if buffering is significant, pH monitoring may not effectively detect CO2 leakage. This study also highlights potential complications that CO{sub 2}carrier fluids, such as saline waters, pose in monitoring impacts ofgeologic sequestration.

    The U.S. Department of Energy and its predecessor agencies conducted a program in the 1960s and 1970s that evaluated technology for the nuclear stimulation of low-permeability gas reservoirs. The third and final project in the program, Project Rio Blanco, was conducted in Rio Blanco County, in northwestern Colorado. In this experiment, three 33-kiloton nuclear explosives were simultaneously detonated in a single emplacement well in the Mesaverde Group and Fort Union Formation, at depths of 1,780, 1,899, and 2,039 m below land surface on May 17, 1973. The objective of this work is to estimate lateral distances that tritium released from the detonations may have traveled in the subsurface and evaluate the possible effect of postulated natural-gas development on radionuclide migration. Other radionuclides were considered in the analysis, but the majority occur in relatively immobile forms (such as nuclear melt glass). Of the radionuclides present in the gas phase, tritium dominates in terms of quantity of radioactivity in the long term and contribution to possible whole body exposure. One simulation is performed for {sup 85}Kr, the second most abundant gaseous radionuclide produced after tritium.

    This research was based on ozone decomposition in industrial environment. Ozone is harmful to human. Therefore, catalysts were made as a mask filter to decompose ozone. Comparison studies of catalyst supports were done using Granular Activated Carbon (GAC), Natural Zeolite (NZ), and Green Sand (GS). GAC showed the highest catalytic activity compared to other supports with conversion of 98%. Meanwhile, the conversion using NZ was only 77% and GS had been just 27%. GAC had the highest catalytic activity because it had the largest pore volume, which is 0.478 cm3/g. So GAC was used as catalyst supports. To have a higher conversion in ozone decomposition, GAC was impregnated with metal oxide as the active site of the catalyst. Active site comparison was made using CuOX and ZnO as the active site. Morphology, composition, and crystal phase were analyzed using SEM-EDX, XRF, and XRD methods. Mask filter, which contained catalysts for ozone decomposition, was tested using a fixed bed reactor at room temperature and atmospheric pressure. The result of conversion was analyzed using iodometric method. CuOX/GAC and ZnO/GAC 2%-w showed the highest catalytic activity and conversion reached 100%. From the durability test, CuOX/GAC 2%-w was better than ZnO/GAC 2%-w because the conversion of ozone to oxygen reached 100% with the lowest conversion was 70% for over eight hours.

  12. Absence of Non-histone Protein Complexes at Natural Chromosomal Pause Sites Results in Reduced Replication Pausing in Aging Yeast Cells

    2016-11-01

    Full Text Available There is substantial evidence that genomic instability increases during aging. Replication pausing (and stalling at difficult-to-replicate chromosomal sites may induce genomic instability. Interestingly, in aging yeast cells, we observed reduced replication pausing at various natural replication pause sites (RPSs in ribosomal DNA (rDNA and non-rDNA locations (e.g., silent replication origins and tRNA genes. The reduced pausing occurs independent of the DNA helicase Rrm3p, which facilitates replication past these non-histone protein-complex-bound RPSs, and is independent of the deacetylase Sir2p. Conditions of caloric restriction (CR, which extend life span, also cause reduced replication pausing at the 5S rDNA and at tRNA genes. In aged and CR cells, the RPSs are less occupied by their specific non-histone protein complexes (e.g., the preinitiation complex TFIIIC, likely because members of these complexes have primarily cytosolic localization. These conditions may lead to reduced replication pausing and may lower replication stress at these sites during aging.

    Ten uncommon natural type 3/type 2 intertypic poliovirus recombinants were isolated from stool specimens from nine acute flaccid paralysis case patients and one healthy vaccinee in China from 2001 to 2008. Complete genomic sequences revealed their vaccine-related genomic features and showed that their first crossover sites were randomly distributed in the 3' end of the VP1 coding region. The length of donor Sabin 2 sequences ranged from 55 to 136 nucleotides, which is the longest donor sequence reported in the literature for this type of poliovirus recombination. The recombination resulted in the introduction of Sabin 2 neutralizing antigenic site 3a (NAg3a) into a Sabin 3 genomic background in the VP1 coding region, which may have been altered by some of the type 3-specific antigenic properties, but had not acquired any type 2-specific characterizations. NAg3a of the Sabin 3 strain seems atypical; other wild-type poliovirus isolates that have circulated in recent years have sequences of NAg3a more like the Sabin 2 strain. 10 natural type 3/type 2 intertypic VP1 capsid-recombinant polioviruses, in which the first crossover sites were found to be in the VP1 coding region, were isolated and characterized. In spite of the complete replacement of NAg3a by type 2-specific amino acids, the serotypes of the recombinants were not altered, and they were totally neutralized by polyclonal type 3 antisera but not at all by type 2 antisera. It is possible that recent type 3 wild poliovirus isolates may be a recombinant having NAg3a sequences derived from another strain during between 1967 and 1980, and the type 3/type 2 recombination events in the 3' end of the VP1 coding region may result in a higher fitness.

    2002-07-15

    Calgary based Vision Quest Windelectric has been given zoning approval to install a 22 MW windfarm in Ontario's Prince Edward County. Following a preliminary screening to determine the effect of the windfarm on the natural environment, the Royal Road Windfarm will be developed in stages with up to 32 turbines. Jacques Whitford Environment Ltd. conducted an environmental study which showed that an exploratory wind turbine in the area is not likely to cause major adverse impacts on local fauna and flora. The proposed location of the wind turbine is not in an important bird area (IBA). An IBA is defined as a site providing essential habitat for one of more species of breeding or non-breeding birds. In 1999, Vision Quest initiated a program to examine bird interactions with wind turbines in southern Alberta. It was shown that most species choose flight paths to avoid turbines. The Royal Road site hosts rare alvars which are naturally open landscapes found in shallow soils on flat limestones. The alvars are subject to seasonal drought and flooding and have specific types of vegetation and animals. Since the exploratory wind turbine will be placed outside the IBA area, its impact on birds will be minimized, and it will have minimal effect on migrant, breeding and wintering birds. It was recommended that monitoring take place at the site during the first year of operation. It is also presumed that the wind turbine will not have any impact on mammals, reptiles and amphibians, or insects. However, it was recommended that more information be gathered on bat movement in the area. If placed appropriately, the wind turbine is not expected to impact on rare plants. It was emphasized that in the past, Vision Quest Windelectric has conducted environmental screening activities, and has acted on recommendations to place wind turbines in locations where environmental impact will be minimized. 26 refs., 5 tabs., 2 figs., 2 appendices.

    Clinical nursing practice uses professional nursing techniques, empathy, and moral judgment to help relieve the pain of patients who are suffering physically or mentally from trauma or illness. Thus, nursing involves sacred tasks. According to Confucian reasoning, morality is expressed through everyday actions. Providing care to patients arouses concern and sympathy in the caregiver, which induces him or her to fully apply professional knowledge to this task. This conduct demonstrates the moral conscience of nurses. The Chinese adage "Tian-tao hsing-ming hsiang kuan tung" (the way of heaven and life are correlated), attributed to Northern Song dynasty scholar Zhang Tsai, aptly explains the sacred mission of the nursing profession. Zhang held that all humans are born with a conscience that is given by heaven. However, human senses and desires may suppress this conscience. As Zhang Tsai suggested, the conscience must be cultivated in order to be manifested. The increase in recent years of international academic discussion / research related to the value and meaning of nursing and of exploration into how to promote the moral competence of nurses, not only provide support to Zhang's argument that "tian-tao" and "hsing-ming" are correlated but also provide positive momentum toward enhancing the self-worth of nurses and enabling patients to receive better care.

    Full Text Available We examine an application of Acoustic Emission (AE technique for a probabilistic analysis in time and space of earthquakes, in order to preserve the valuable Italian Renaissance Architectural Complex named “The Sacred Mountain of Varallo.” Among the forty-five chapels of the Renaissance Complex, the structure of the Chapel XVII is of particular concern due to its uncertain structural condition and due to the level of stress caused by the regional seismicity. Therefore, lifetime assessment, taking into account the evolution of damage phenomena, is necessary to preserve the reliability and safety of this masterpiece of cultural heritage. A continuous AE monitoring was performed to assess the structural behavior of the Chapel. During the monitoring period, a correlation between peaks of AE activity in the masonry of the “Sacred Mountain of Varallo” and regional seismicity was found. Although the two phenomena take place on very different scales, the AE in materials and the earthquakes in Earth’s crust, belong to the same class of invariance. In addition, an accurate finite element model, performed with DIANA finite element code, is presented to describe the dynamic behavior of Chapel XVII structure, confirming visual and instrumental inspections of regional seismic effects.

  19. Imagining Exodus for Israel-Palestine: Reading the Secular and the Sacred, Diaspora and Homeland, in Edward Said and David Grossman

    Directory of Open Access Journals (Sweden)

    Anna Hartnell

    2005-03-01

    Full Text Available This paper takes as its starting point Edward Said's distinction between 'religious' and 'secular' modes of cultural affiliation. As these simultaneously diverging and converging modes also trammel the particular grounds of thinking that have been Said's natural target of criticism - Zionism - his work speaks particularly powerfully to the debate surrounding the religious genealogy of Jewish identity. This paper argues that Said's interventions on Zionism highlight as problematic the position whereby the 'Ingathering of the Exiles' is promoted as coexisting with a 'diasporic consciousness' nurtured by Judaism during exile; messianic hopes of religious Jews cannot be reconciled with physical return to the Promised Land; identity circumscribed by ethnicity and place cannot stand in as exemplary for the exiled, unsettled and ultimately homeless identity trumpeted by discourses of the 'post', as many contemporary theorists would have it. And yet through an exploration of the writings of David Grossman, whose construction of Jewish identity is envisaged through the regulating, competing and collaborating tropes of Zionism and Diaspora, I argue that this position is crucial for the elaboration of Israeli identity. I also argue that in fact there is room within Said's thinking both for the anti-essentialist elaboration of 'homeless' identities as well as 'the permission to narrate' an identity politics, and that his own distinction between the 'secular' and the 'religious' begins to disassemble. I explore this blurring of the sacred and the secular through the prism of Exodus - as both concept and narrative. This paper suggests that it is precisely Said's achievement to embody these tensions between religion and its other, divine providence and human agency, historical materialism and postmodernism, alienation and its perennially tempting opposite: home.

  20. Evaluation of host rocks and background lithologies as secondary contributors to the uranium and rare-earth element source-term at the Needle's Eye natural analogue site

    HMIP has a research programme investigating some naturally radioactive sites in the UK as geochemical analogues of radionuclide migration. The objective is to test thermodynamic database and computer codes used for modelling radionuclide migration under environmental conditions. This report describes a study of the distributions of uranium (U) and the rare-earth elements (REE) in the vicinity of pitchblende veins outcropping in the cliff at Needle's Eye on the Solway Coats, SW Scotland. This report improves the information available on the secondary source-terms of U and REE. The minerals in the country rocks are thought to be supplying only minor amounts of these elements to the groundwaters flowing into the Merse silts within the detailed study area close to the mineralisation in the cliff. The pitchblende veins are the principal source-term for U migrating into the Merse silts at the foot of the cliff. (author)

    Reproducing the naturally occurring O{sub 2}-tolerant hydrogenases is a potential strategy to make the oxygen sensitive enzymes, produced by organisms of biotechnological interest, more resistant. The search for resistance ''hotspots'' that could be transposed into sensitive hydrogenases is underway. Here, we replaced two residues (Y77 and V78) of the oxygen sensitive [NiFe] hydrogenase from Desulfovibrio fructosovorans with Gly and with Cys, respectively, to copy the active site pocket of the resistant membrane-bound [NiFe] enzyme from Ralstonia eutropha and we examined how this affected oxygen sensitivity. The results are discussed in the light of a short review of the recent results dealing with the reactivity of hydrogenases towards oxygen. (author)

The focus was on (1) using {sup 13}C to evaluate natural chlorinated ethene biodegradation and the ZVI-PRB efficiency; (2) using dual element {sup 13}C-{sup 37}Cl isotopic analysis to distinguish biotic from abiotic degradation of cis-dichloroethene (cis-DCE); and (3) using {sup 13}C-{sup 37}Cl-{sup 2}H isotopic analysis of cis-DCE and TCE to elucidate different contaminant sources. Both biodegradation and degradation by ZVI-PRB were indicated by the metabolites that were detected and the {sup 13}C data, with a quantitative estimate of the ZVI-PRB efficiency of less than 10% for PCE. Dual element {sup 13}C-{sup 37}Cl isotopic plots confirmed that biodegradation was the main process at the site including the ZVI-PRB area. Based on the carbon isotope data, approximately 45% and 71% of PCE and TCE, respectively, were estimated to be removed by biodegradation. {sup 2}H combined with {sup 13}C and {sup 37}Cl seems to have identified two discrete sources contributing to the contaminant plume, indicating the potential of δ{sup 2}H to discriminate whether a compound is of industrial origin, or whether a compound is formed as a daughter product during degradation.

    15N NMR assignments were made to the backbone amide nitrogen atoms at natural isotopic abundance of intact and reactive-site (Arg5-Ile6) hydrolyzed Cucurbita maxima trypsin inhibitor III (CMTI-III and CMTI-III*, respectively) by means of 2D proton-detected heteronuclear single bond chemical shift correlation (HSBC) spectroscopy, utilizing the previously made sequence-specific 1H NMR assignments (Krishnamoorthi et al. (1992) Biochemistry 31, 898-904). Comparison of the 15N chemical shifts of the two forms of the inhibitor molecule revealed significant changes not only for residues located near the reactive-site region, but also for those distantly located. Residues Cys3, Arg5, Leu7, Met8, Cys10, Cys16, Glu19, His25, Tyr27, Cys28 and Gly29 showed significant chemical shift changes ranging from 0.3 to 6.1 ppm, thus indicating structural perturbations that were transmitted throughout the molecule. These findings confirm the earlier conclusions based on 1H NMR investigations.

    Sequence-specific hydrogen-1 NMR assignments were made to all of the 29 amino acid residues of reactive-site-hydrolyzed Cucurbita maxima trypsin inhibitor I (CMTI-I*) by the application of two-dimensional NMR (2D NMR) techniques, and its secondary structural elements (two tight turns, a 3(10)-helix, and a triple-stranded beta-sheet) were identified on the basis of short-range NOESY cross peaks and deuterium-exchange kinetics. These secondary structural elements are present in the intact inhibitor [Holak, T. A., Gondol, D., Otlewski, J., & Wilusz, T. (1989) J. Mol. Biol. 210, 635-648] and are unaffected by the hydrolysis of the reactive-site peptide bond between Arg5 and Ile6, in accordance with the earlier conclusion reached for CMTI-III* [Krishnamoorthi, R., Gong, Y.-X., Lin, C. S., & VanderVelde, D. (1992) Biochemistry 31, 898-904]. Chemical shifts of backbone hydrogen atoms, peptide NH's, and C alpha H's, of CMTI-I* were compared with those of the intact inhibitor, CMTI-I, and of the reactive-site-hydrolyzed, natural, E9K variant, CMTI-III*. Cleavage of the Arg5-Ile6 peptide bond resulted in changes of chemical shifts of most of the backbone atoms of CMTI-I, in agreement with the earlier results obtained for CMTI-III. Comparison of chemical shifts of backbone hydrogen atoms of CMTI-I* and CMTI-III* revealed no changes, except for residues Glu9 and His25. However, the intact forms of the same two proteins, CMTI-I and CMTI-III, showed small but significant perturbations of chemical shifts of residues that made up the secondary structural elements of the inhibitors.(ABSTRACT TRUNCATED AT 250 WORDS)

    This radiological impacts evaluation covered of radioactivity in water, soil, grass, air samples and ambient gamma radiation that have been carried out in the Kartini reactor area and in the site plan of nuclear power plan are at Ujung Lemah Abang, Jepara, Central Java. The aim of this research was to determine that radiological impacts in the environment around the Kartini reactor compared to natural radioactivity for site plan of nuclear power plan area. The radioactivity in the water, soil and grass samples ware measured by low background beta counting system and were identified by low background gamma spectrometer. The radioactivity in the air samples was measured by beta portable counting system and the ambient gamma radiation was measured by portable high pressurized ionization chamber model RSS-112 Reuther-Stokes. The reactor data measurement was compared to the site plan of nuclear power plant area data for evaluation of radiological impacts on the operating reactor. From the evaluation and comparison can be concluded there are no indication of the radionuclide release from the reactor operation. The average radiactivity in the water, soil grass and air sample from the reactor area were between 0.17 - 0.61 Bq/1; 0,47 - 0,74 Bq/g; 4.43 - 4.60 Bq/g.ash and 49.53 - 70.90 x 10 Bq/cc. The average radioactivity of those sample from the nuclear power plant area were between 0.06-0.90 Bq/I; 0.02-0.86 Bq/g; 1.68-8.07 Bq/g.ash and 65.0-152.3 x 10 Bq/cc. The ambient gamma radiation were between 6.9-36.7 urad/h for the reactor area and 6.8-19.2 urad/h for the nuclear power plant area

    In May, 2017, the U.S. Department of the Interior's Bureau of Ocean Energy Management (BOEM) published a high-resolution seafloor map of the northern Gulf of Mexico region. The new map, derived from 3-D seismic surveys, provides the scientific community with enhanced resolution and reveals previously undiscovered and poorly resolved geologic features of the continental slope, salt minibasin province, abyssal plain, Mississippi Fan, and the Florida Shelf and Escarpment. It becomes an even more powerful scientific tool when paired with BOEM's public database of 35,000 seafloor features, identifying natural hydrocarbon seeps, hard grounds, mud volcanoes, sediment flows, pockmarks, slumps, and many others. BOEM has mapped the Gulf of Mexico seafloor since 1998 in a regulatory mission to identify natural oil and gas seeps and protect the coral and chemosynthetic communities growing at those sites. The nineteen-year mapping effort, still ongoing, resulted in the creation of the 1.4-billion pixel map and the seafloor features database. With these tools and continual collaboration with academia, professional scientific institutions, and the offshore energy industry, BOEM will continue to incorporate new data to update and expand these two resources on a regular basis. They can be downloaded for free from BOEM's website at https://www.boem.gov/Gulf-of-Mexico-Deepwater-Bathymetry/ and https://www.boem.gov/Seismic-Water-Bottom-Anomalies-Map-Gallery/.

    Full Text Available The main purpose of this paper is to study the connections that can be established between the modern abstractionism and the abstract tendencies from other historical eras. In the first part I will present three distinct interpretations: the first direction is based on authors as Mircea Eliade and Roger Lipsey, who see modern art through the links still alive between art and religion, from a syncretic perspective, or, after Eliade’s expression, based on a creative hermeneutics. The second direction is represented by the work of Adorno, Compagnon, Greenberg, Lyotard, for whom the modern art is a manifestation of radical discontinuity in relation to the art of the past, and the emergence of abstractionism is due primarily to a historical necessity (the increasing rupture between form and content, the increased autonomy of the sensible over the intelligible. The third direction is represented to Wilhelm Worringer, whose work (Abstraktion und Einfühlung, 1907 predates the emergence of the first abstract paintings, but relying on the German aesthetic tradition, manages to go beyond the threshold distinction between figurative and abstract, thus identifying a type of Einfühlung art and another of abstract type, namely the predominance of one or the other in different historical contexts and civilizational patterns. In the second part of the paper I will refer to instances of the spirit of abstraction in the case of Byzantine sacred art, especially in the footsteps of Plotinian aesthetics and as a result of the iconoclastic crisis. In the last part, I will present the key ideas for three major representatives of abstractionism (Kandinsky, Klee, Mondrian and the survival of the concepts of sacred art in their works and art theories.

    Whole body monitoring of a worker showed an apparent internal contamination with a considerable amount of {sup 95}Zr-{sup 95}Nb. Inhalation exposure was suspected to have taken place about a week earlier when he had last worked in the radioactive area. Unexpected fast clearance indicated by the third periodical weekly follow up monitoring was considered to be an abnormal behaviour. Investigations revealed an external contamination on a sacred thread, which the worker was putting on across his thorax and not removing it at the time of bath due to religious considerations. These studies have underscored that short term follow up measurements data should be critically scrutinized and a caution should be exercised in the interpretation such data particularly in case of such relatively short lived radionuclides.

    This article presents research findings based on the meaning of indigenous circumcision to Xhosa men in South Africa. In South Africa, male circumcision is a rite of passage from adolescence to adulthood. The country has experienced serious problems associated with the practice of this rite ranging from dehydration to death in the traditional "bush" circumcision schools. A qualitative, endogenous research "How do you experience having a son who is undergoing the circumcision rite?" The study revealed cultural circumcision as a "sacred religious practice" with five themes, namely (a) readiness of Xhosa families to engage in the circumcision ritual, (b) the act of circumcision and preparation for manhood, (c) the importance of symbolic purity during the circumcision ritual, (d) celebrating acquired manhood, and (5) aspects of manhood and the rejection of clinical care. Secondary to this are health promotion recommendations made for individuals involved in this ritual.

    2009-04-01

    Full Text Available The article seeks to respond to the question: What role can the sacred texts play in the construction of a Christian identity that is responsible to the Other in a pluralistic global world? The sacred texts of the Judaic-Christian tradition offer not only an understanding of the wholly otherness of God, but also form the basis of our understanding and perception of humanity (anthropology, the world and ourselves (personhood/identity. This understanding is constructed in the context of responding to the call of the wholly Other and the others. Identities are traditionally constructed through the identification and exclusion of differences (otherness, thus leading to an ethic of exclusion and responsibility only to oneself/ourselves. Yet these identity-forming texts harbour a persistent otherness, which challenges these traditional identities by interrupting them with a call to responsibility toward the other. The otherness harboured in these texts takes various forms, namely: The otherness of the ancient world to our world, the otherness of the transcendental Other, and the otherness of the text itself, as there is always a différance that has not yet been heard. These various forms of otherness, of our identity-forming texts, deconstruct our identity constructions, thus calling us to a continuous responsibility towards the other. This call could form the basis of a Christian identity and ethic of global cosmopolitan citizenship that is always responding to the eschatological interruption by the other, who is not yet present or who has not been offered presence.

    Full Text Available On 16 April 2014, the Supreme Court of Appeal handed down judgment in the matter of S v Litako 2014 2 SACR 431 (SCA ("Litako". The judgment reconsiders the landmark decision of the same court, S v Ndhlovu 2002 2 SACR 325 (SCA ("Ndhlovu" in which the court held that an informal admission made by one accused could be admitted against a co-accused even if the accused in court denies making the statement and the statement itself is therefore considered to be hearsay. The court in Ndhlovu applied section 3 of the Law of Evidence Amendment Act 45 of 1988 and found that the hearsay extra curial admission could be admitted in the interests of justice. In Litako the court found that section 3 did not overrule an existing common law rule, which is that the extra curial statement of an accused (whether an informal admission or a confession cannot be tendered against a co-accused. This is because section 3 does not expressly overrule this common law rule. Rather, the provision itself requests that its application be subject to the common law. The judgment is important for various reasons. Firstly, it is generally in keeping with the existing rule on the cautionary treatment of accomplice evidence. Secondly, the judgment highlights the current confusion in the relationship between statute and common law with regards to informal admissions and confessions. Thirdly, the court employs methods of statutory interpretation to re-examine the principle from Ndhlovu and finds that the court in that case did not apply its mind correctly in disregarding the common law rule. The court undertook a teleological approach to interpretation by infusing the meaning of the words with the spirit, purport and objects of the Bill of Rights and found that the statute had not overruled the common law rule.

    Following the legislative EU targets and taking advantage of its high renewable energy potential, Greece can obtain significant benefits from developing its water, solar and wind energy resources. In this context we present a GIS-based methodology for the optimal sizing and siting of solar and wind energy systems at the regional scale, which is tested in the Prefecture of Thessaly. First, we assess the wind and solar potential, taking into account the stochastic nature of the associated meteorological processes (i.e. wind speed and solar radiation, respectively), which is essential component for both planning (i.e., type selection and sizing of photovoltaic panels and wind turbines) and management purposes (i.e., real-time operation of the system). For the optimal siting, we assess the efficiency and economic performance of the energy system, also accounting for a number of constraints, associated with topographic limitations (e.g., terrain slope, proximity to road and electricity grid network, etc.), the environmental legislation and other land use constraints. Based on this analysis, we investigate favorable alternatives using technical, environmental as well as financial criteria. The final outcome is GIS maps that depict the available energy potential and the optimal layout for photovoltaic panels and wind turbines over the study area. We also consider a hypothetical scenario of future development of the study area, in which we assume the combined operation of the above renewables with major hydroelectric dams and pumped-storage facilities, thus providing a unique hybrid renewable system, extended at the regional scale.

    1982-07-01

    A goal of this study was to acquire more complete baseline data on the existing flora of the Uranium City region, both in natural and human-disturbed sites. Emphasis was given to determining which plant species were naturally revegetating various abandoned uranium mine and mill waste disposal areas, other human-disturbed sites, and ecologically analogous sites. Another goal was to document the occurrence and distribution in the study region of rare and possibly endangered species. A further objective was to suggest regionally-occurring species with potential value for revegetating uranium mine and mill waste sites. Field investigations were carried out in the Uranium City region during August, 1981. During this time 1412 plant collections were made; a total of 366 plant species - trees, shrubs, forbs, graminoids, lichens, and bryophytes were recorded. The report includes an annotated checklist of plant species of the Uranium City region and a reference index of plant taxa indicating species that have high revegetation potential

This characterization is compatible with the assumption that a sacred moral world is easily threatened by reality and that may be associated to violent defensive actions. The results from latent class analyses reveal (a) a 4-class distribution depending exclusively on the intensity with which all participants (violent and nonviolent) tend to sacralize the actions proposed in the Moral Foundations Sacredness Scale and (b) a greater prevalence of the violent participants among the classes that are more prone to sacralize. They also show that they hold an inflated moral vision of themselves: They think they are much more moral than intelligent than others who have never been charged with criminal behavior (Muhammad Ali effect).

    Hawaiian forest birds have declined dramatically since humans arrived in the archipelago. Birds from all foraging guilds have been affected but insectivorous species are currently at greatest risk of extinction. On the island of Maui, populations and ranges of the insectivorous kiwikiu (Maui parrotbill; Pseudonestor xanthophrys) and Maui ‘alauahio (Maui creeper; Paroreomyza montana) have declined significantly from historic levels primarily due to habitat loss, predation,disease, and food web disruption, leading to federal listings of endangered species and species of concern, respectively. Recovery plans for these birds include reestablishment of populations in parts of their former range. Nakula Natural Area Reserve on the leeward side of HaleakalāVolcano has been targeted for release of wild-caught or captive-bred individuals. The mesic, montane koa-‘ōhi‘a (Acacia koa-Metrosideros polymorpha) forest at Nakula has been heavily impacted through grazing by feral ungulates, but recent management actions to exclude these animals are promoting forest recovery. The objective of this study was to assess the arthropod prey base at Nakula in preparation for reintroductions of kiwikiu and Maui ‘alauahio. To accomplish that goal, we compared arthropod abundances at Nakula to those at Hanawi Natural Area Reserve and Waikamoi Preserve, areas where kiwikiu and Maui ‘alauahio are currently found. We also identified diets of kiwikiu and Maui ‘alauahio from fecal samples to better understand and evaluate the prey base at Nakula. Assessment methods included clipping branch tips to sample arthropods within the foliage of koa and ‘ōhi‘a, using traps to quantify arthropods on koa and ‘ōhi‘a bark surfaces, counting exit holes to quantify abundances of beetles (Coleoptera) within dead branches of koa, and measuring the density of arthropods within the stems of ‘ākala (Rubus hawaiiensis). The diet of kiwikiu was dominated by caterpillars (Lepidoptera larvae

    Microbes exist in communities in the environment where they are fundamental drivers of global carbon, nutrient and metal cycles. In subsurface environments, they possess significant metabolic potential to affect these global cycles including the transformation of radionuclides. This study examined the influence of microbial communities in sediment zones undergoing biogeochemical cycling of carbon, nutrients and metals including natural attenuation of uranium. This study examined the relationship of both the microbiota (taxonomy) and their metabolic capacity (function) in driving carbon, nutrient and metal cycles including uranium reduction at the Department of Energy (DOE) Rifle Integrated Field Research Challenge (RIFRC). Objectives of this project were: 1) to apply systems-level biology through application of ‘metaomics’ approaches (collective analyses of whole microbial community DNA, RNA and protein) to the study of microbial environmental processes and their relationship to C, N and metals including the influence of microbial communities on uranium contaminant mobility in subsurface settings undergoing natural attenuation, 2) improve methodologies for data generation using metaomics (collectively metagenomics, metatranscriptomics and proteomics) technologies and analysis and interpretation of that data and 3) use the data generated from these studies towards microbial community-scale metabolic modeling. The strategy for examining these subsurface microbial communities was to generate sequence reads from microbial community DNA (metagenomics or whole genome shotgun sequencing (WGS)) and RNA (metatranscriptomcs or RNAseq) and protein information using proteomics. Results were analyzed independently and through computational modeling. Overall, the community model generated information on the microbial community structure that was observed using metaomic approaches at RIFRC sites and thus provides an important framework for continued community modeling

    Full Text Available Power grid becomes smarter nowadays along with technological development. The benefits of smart grid can be enhanced through the integration of renewable energy sources. In this paper, several studies have been made to reconfigure a conventional network into a smart grid. Amongst all the renewable sources, solar power takes the prominent position due to its availability in abundance. Proposed methodology presented in this paper is aimed at minimizing network power losses and at improving the voltage stability within the frame work of system operation and security constraints in a transmission system. Locations and capacities of DGs have a significant impact on the system losses in a transmission system. In this paper, combined nature inspired algorithms are presented for optimal location and sizing of DGs. This paper proposes a two-step optimization technique in order to integrate DG. In a first step, the best size of DG is determined through PSO metaheuristics and the results obtained through PSO is tested for reverse power flow by negative load approach to find possible bus locations. Then, optimal location is found by Loss Sensitivity Factor (LSF and weak (WK bus methods and the results are compared. In a second step, optimal sizing of DGs is determined by PSO, GSA, and hybrid PSOGSA algorithms. Apart from optimal sizing and siting of DGs, different scenarios with number of DGs (3, 4, and 5 and PQ capacities of DGs (P alone, Q alone, and  P and Q both are also analyzed and the results are analyzed in this paper. A detailed performance analysis is carried out on IEEE 30-bus system to demonstrate the effectiveness of the proposed methodology.

    We have produced and purified an active site mutant of the Escherichia coli cyclopropane fatty acid synthase (CFAS) by replacing the strictly conserved G236 within cyclopropane synthases, by a glutamate residue, which corresponds to E146 of the homologous mycolic acid methyltransferase, Hma, producing hydroxymethyl mycolic acids. The G236E CFAS mutant had less than 1% of the in vitro activity of the wild type enzyme. We expressed the G236E CFAS mutant in an E. coli (DE3) strain in which the chromosomal cfa gene had been deleted. After extraction of phospholipids and conversion into the corresponding fatty acid methyl esters (FAMEs), we observed the formation of cyclopropanated FAMEs suggesting that the mutant retained some of the normal activity in vivo. However, we also observed the formation of new C17 methyl-branched unsaturated FAMEs whose structures were determined using GC/MS and NMR analyses. The double bond was located at different positions 8, 9 or 10, and the methyl group at position 10 or 9. Thus, this new FAMEs are likely arising from a 16:1 acyl chain of a phospholipid that had been transformed by the G236E CFAS mutant in vivo. The reaction catalyzed by this G236E CFAS mutant thus starts by the methylation of the unsaturated acyl chain at position 10 or 9 yielding a carbocation at position 9 or 10 respectively. It follows then two competing steps, a normal cyclopropanation or hydride shift/elimination events giving different combinations of alkenes. This study not only provides further evidence that cyclopropane synthases (CSs) form a carbocationic intermediate but also opens the way to CSs engineering for the synthesis of non-natural fatty acids.

  7. Die Versprachlichung des Sakralen: The Transformation of the Authority of the Sacred into Secular Political Deliberation in Habermas’ Theory of Communicative Action

    Directory of Open Access Journals (Sweden)

    Øjvind Larsen

    2011-03-01

    Full Text Available bermas claims in connection with his development of the theory of communicative action that the sacred is transformed in a positive way and can take the form of free deliberation in society, the so called Versprachlichung des Sakralen. The thesis is that the authority which could be found in religion and which is of fundamental significance for the integration of pre-modern societies is taken over by modern societies in forms of deliberation. Habermas develops his thesis in a discussion of Durkheim’s religious-sociological considerations. Habermas presents his thesis about the linguistic transformation of the sacred as a harmonious theory of secularization. However, if we follow Weber in his religious-sociological considerations of modernity, we reach a tragic theory of secularization which poses the real problem that modernity’s connection to the sacred has been dissolved. Cornelius Castoriadis’ theory of the imaginary institution and Claude Lefort’s theory of the empty place of the political as a new insecure moral ground for modern society are presented together as an alternative theory of secularization which can serve as a new framework for Habermas’ theory of communicative ethics and deliberative politics in modern society.

  8. Defining "natural product" between public health and business, 17th to 21st centuries.

    Stanziani, Alessandro

    2008-07-01

    The historical definition of a natural product stands at the crossroads of business, health, and the symbolic order of things. Until the end of the 19th century, "natural product" was a synonym of perishable. The emergency of organic chemistry made perishability be replaced with "toxicity". Nowadays, genetics is provoking a radical change in the notion and practises of "natural product". However, these concerns are never entirely opposed to "naturality" as a synonym for sacred and symbolic order. Traceability is largely based upon kosher practices and the association between organic and good for health is hardly based upon sound scientific arguments.

    Full Text Available It is currently difficult to highlight the problem of structures which belonged to septentrional thracians both within themselves as well as their internal planning. The case in the Saharna microzone allows us to determine their placement in “nest”, while Little Horodca demonstrates their placement in a row, alongside the valley of Botna. Each of these agglomerations evolves around a fortress-centre. As to their internal structure, we can also observe their placement in rows. In Alcedar we see the presence of a fence which was likely serving as a circling of households. With some objects a public centre was observed – ie. market in the middle of town, surrounded by more pretentious buildings. In many cases, some structures with sacred meaning were discovered – both public and individual. Lately we have observed the promotion of the cultural and archaeological landscape as it highlights the interaction between human, nature, and environment. Only in this way can we reconstruct the livelihoods, every day interactions, productions, and secret believes of the population.

  11. "We share a sacred secret": gender, domesticity, and containment in Transvestia's histories and letters from crossdressers and their wives.

    2011-01-01

    After WWII in the United States, gender and sexual minorities began to construct social identities in a cold war climate hostile to gender and sexual transgression. The coming of the sexual revolution in the mid-1960s and 1970s unleashed forces that provided opportunities for these groups to demarcate their differences from one another, achieve visibility, and court public favor in a more permissive and tolerant society. In this article, I examine how a cohort of white, heterosexual crossdressers and their wives forged a redeeming social script in ways that seem counterintuitive to the "spirit of the times." The presence of transvestism within the sacred, idealized space of the American home produced tremendous anxiety on the part of these transvestite husbands and especially their wives. To deflect the stigma of sexual deviancy and sooth feelings of insecurity, these couples utilized strategies of containment and embraced the domestic ideal, even well into the sexualized and swinging seventies. Their strategic yet curious retreat into domesticity compels a second look at the consensus, conformity, and containment narratives that once dominated our scholarly imagination of intimate matters during the postwar years. Might current revisionist histories have gone too far in discrediting these potent forces? How do gender and sexual populations beholden to whiteness and notions of respectability fit within the sexual revolutions of postwar America?

    Single-seeded fruit of the sacred lotus Nelumbo nucifera Gaertn var. China Antique from NE China have viability as long as ~1300 years determined by direct radiocarbon-dating, having a germination rate of 84%. The pericarp, a fruit tissue that encloses the single seeds of Nelumbo , is considered one of the major factors that contribute to fruit longevity. Proteins that are heat stable and have protective function may be equally important to seed viability. We show proteins of Nelumbo fruit that are able to withstand heating, 31% of which remained soluble in the 110°C-treated embryo-axis of a 549-yr-old fruit and 76% retained fluidity in its cotyledons. Genome of Nelumbo is published. The amino-acid sequences of 11 "thermal proteins" (soluble at 100°C) of modern Nelumbo embryo-axes and cotyledons, identified by mass spectrometry, Western blot and bioassay, are assembled and aligned with those of an archaeal-hyperthermophile Methancaldococcus jannaschii (Mj; an anaerobic methanogen having a growth optimum of 85°C) and with five mesophile angiosperms. These thermal proteins have roles in protection and repair under stress. More than half of the Nelumbo thermal proteins (55%) are present in the archaean Mj, indicating their long-term durability and history. One Nelumbo protein-repair enzyme exhibits activity at 100°C, having a higher heat-tolerance than that of Arabidopsis. A list of 30 sequenced but unassembled thermal proteins of Nelumbo is supplemented.

    2018-03-01

    Full Text Available The article examines the history of the idea of connection, succession, and hereditybetween Old Rus’, on the one hand, and such ancient political and spiritual centers ofthe Christian world as Jerusalem, Rome, and Constantinople on the other, within theOld Russian political thought. This idea was never documented in particular treatisesbut was nonetheless present in fictional, polemical and didactic works whether as amarginal or central theme, whether directly or allegorically. The author of the article considerably extends the circle of sources that drew retrospective analogies between Russian history and Sacred Land history. Indirect parallels in the “Word about the Law and the Grace” become explicit and specific in the hagiographic legend about Kiev Prince Vladimir Svyatoslavich and later recur, with different accents, in a number of literary texts in the 15 th –17 th centuries, reflecting the course of Russian history. In these texts, we encounter a division between Rome as a symbol of imperial mundane power associated with state politics, and Jerusalem as a symbol of the Kingdom of God associated with church and religion.

    Large areas of natural peat bogs in Northwestern Germany have been converted to arable land and were subjected to draining and peat cutting in the past. The few protected peatland areas remaining are affected by high nitrogen (N) deposition. Our study site - a moderately drained raised bog - is surrounded by highly fertilized agricultural land and livestock production. In this study, we used a 15N pool dilution technique called 'Integrated Total Nitrogen Input' (ITNI) to quantify annual deposition of atmospheric N into biomonitoring pots over a two-year period. Since it considers direct N uptake by plants, it was expected to result in higher N input than conventional methods for determination of N deposition (e.g. micrometeorological approaches, bulk N samplers). Using Lolium multiflorum and Eriophorum vaginatum as monitor plants and low, medium and high levels of fertilization, we aimed to simulate increasing N deposition to planted pots and to allocate airborne N after its uptake by the soil-plant system in aboveground biomass, roots and soil. Increasing N fertilization was positively correlated with biomass production of Eriophorum vaginatum, whereas atmospheric plant N uptake decreased and highest airborne N input of 899.8 ± 67.4 µg N d-1 pot-1 was found for low N fertilization. In contrast, Lolium multiflorum showed a clear dependency of N supply on plant N uptake and was highest (688.7 ± 41.4 µg N d-1 pot-1) for highly fertilized vegetation pots. Our results suggest that grass species respond differently to increasing N input. While crop grasses such as Lolium multiflorum take up N according to N availability, species adopted to nutrient-limited conditions like Eriophorum vaginatum show N saturation effects with increasing N supply. Total airborne N input ranged from about 24 to 66 kg N ha-1 yr-1 dependent on the used indicator plant and the amount of added fertilizer.

    2010-09-01

    The Gihon Spring, Jerusalem, is important for the major monotheistic religions. Its hydrogeology and hydrochemistry is studied here in order to understand urbanization effects on karst groundwater resources, and promote better water management. High-resolution monitoring of the spring discharge, temperature and electrical conductivity, was performed, together with chemical and bacterial analysis. All these demonstrate a rapid response of the spring to rainfall events and human impact. A complex karst system is inferred, including conduit flow, fissure flow and diffuse flow. Electrical conductivity, Na+ and K+ values (2.0 mS/cm, 130 and 50 mg/l respectively) are very high compared to other nearby springs located at the town margins (0.6 mS/cm, 15 and <1 mg/l respectively), indicating considerable urban pollution in the Gihon area. The previously cited pulsating nature of the spring was not detected during the present high-resolution monitoring. This phenomenon may have ceased due to additional water sources from urban leakage and irrigation feeding the spring. The urbanization of the recharge catchment thus affects the spring water dramatically, both chemically and hydrologically. Appropriate measures should therefore be undertaken to protect the Gihon Spring and other karst aquifers threatened by rapid urbanization.

    2016-06-01

    Full Text Available Guardians of Nature is a clearly written and very insightful view of the political economic, environmental, and social-cultural transformations reshaping lives and livelihoods on the Tibetan Plateau. Written as a first-hand narrative account of his work over several years with Yulshul villagers, Tsering Bum’s perceptive book discusses key issues of contemporary Tibetan pastoralism: mining, the importance of the caterpillar fungus economy, resettlement, co-ops, education policy, human-wildlife conflict, and sacred mountains. It also explores quite new phenomena, such as Tibetan pastoralists hiring Han Chinese as herding laborers while living off of caterpillar fungus income, and the rise of feral dogs as a result of the sharp drop in Tibetan mastiff prices. Tsering Bum’s analysis is informed by critiques of nature-culture binaries and illustrates the many effects of perverse policy incentives. Strongly recommended for anyone interested in understanding Tibetan pastoral areas today.

    210 Po is one of the naturally occurring radioactive (T 1/2 : 138.4 d, Energy: 5.297 MeV) member of 238 U series which delivers a significantly high natural dose through ingestion because of its high specific activity (165 TBq/g). The main source of 210 Po in atmosphere is 222 Rn. The paper presents the results of analysis of 210 Po in different terrestrial and aquatic environmental matrices like marine seafood, vegetable, drinking water, crop etc and estimation of population dose due to their consumption at Tarapur, west coast of India. The annual Committed Effective Dose (CED) received by the member of Tarapur population through consumption of these food items estimated to be 102.4 μSV which is 6.3 % of the total internal dose from natural sources. Contribution from marine food items was found to be significant (78.7%) compared to other terrestrial food items. (author)

    In this work we investigated an unusual acidity feature of a Cu/SSZ-13 catalyst used in selective catalytic reduction of NOx with NH3 (NH3-SCR). In particular, this catalyst showed two distinct NH3 desorption peaks in NH3-TPD measurements, in contrast to single, unresolved desorption peaks observed for other Cu-exchanged zeolites conventionally used in the SCR studies, including its isostructural but chemically different analogue Cu/SAPO-34. We further observed that the intensities of the two TPD peaks, which represented the amount of stored NH3, changed in opposite directions in response to progressive mild hydrothermal aging, while the total storage capacity was preserved. We proposed an explanation for this remarkable behavior, by using model reference samples and additional characterization techniques. At least three NH3 storage sites were identified: two distinct populations of Cu sites responsible for low-temperature NH3 storage, and Brønsted acid sites responsible for high-temperature NH3 storage. Contrary to the commonly accepted mechanism that Brønsted acid site loss during hydrothermal aging is driven by dealumination, we concluded that the decline in the number of Brønsted acid sites upon mild hydrothermal aging for Cu/SSZ-13 was not due to dealumination, but rather transformation of Cu sites, i.e., gradual conversion of ZCuOH (Cu2+ singly coordinated with Zeolite) to Z2Cu (Cu2+ doubly coordinated with Zeolite). This transformation was responsible for the increased low-temperature desorption peak in NH3-TPD since each ZCuOH adsorbed ~1 NH3 molecule while each Z2Cu adsorbed ~2 NH3 molecules under the conditions used here. These findings were used in Part II of this series of studies to develop a method for quantifying hydrothermal ageing of industrial Cu/SSZ-13 SCR catalysts.

    SummaryThe Gourma site in Mali is one of the three instrumented meso-scale sites deployed in West-Africa as part of the African Monsoon Multi-disciplinary Analysis (AMMA) project. Located both in the Sahelian zone sensu stricto, and in the Saharo-Sahelian transition zone, the Gourma meso-scale window is the northernmost site of the AMMA-CATCH observatory reached by the West African Monsoon. The experimental strategy includes deployment of a variety of instruments, from local to meso-scale, dedicated to monitoring and documentation of the major variables characterizing the climate forcing, and the spatio-temporal variability of surface processes and state variables such as vegetation mass, leaf area index (LAI), soil moisture and surface fluxes. This paper describes the Gourma site, its associated instrumental network and the research activities that have been carried out since 1984. In the AMMA project, emphasis is put on the relations between climate, vegetation and surface fluxes. However, the Gourma site is also important for development and validation of satellite products, mainly due to the existence of large and relatively homogeneous surfaces. The social dimension of the water resource uses and governance is also briefly analyzed, relying on field enquiry and interviews. The climate of the Gourma region is semi-arid, daytime air temperatures are always high and annual rainfall amounts exhibit strong inter-annual and seasonal variations. Measurements sites organized along a north-south transect reveal sharp gradients in surface albedo, net radiation, vegetation production, and distribution of plant functional types. However, at any point along the gradient, surface energy budget, soil moisture and vegetation growth contrast between two main types of soil surfaces and hydrologic systems. On the one hand, sandy soils with high water infiltration rates and limited run-off support almost continuous herbaceous vegetation with scattered woody plants. On the other

    Full Text Available Historians generally argue that Spaniards were not willing to grant Americans equal representation in the Cortes of Cádiz. This article examines the nature of representation in the Antiguo Régimen and the reasons inequality existed in the institutions that emerged after 1808, the Junta Central, the Regency, and the Cortes. Although it is true that the Peninsular majority refused to grant the castas full political rights, they acted to preserve equal representation for themselves in the Cortes. Their actions were predicated on an erroneous belief about the total population of the overseas territories. Opposition to granting the castas full political rights was also shared by some American deputies — those from regions with large African origin population—. Although the Peninsular majority failed to grant Americans the equal representation based on population that they desired, the Spaniards went further than the leaders of any other European nation. England never considered granting the white population of its North American possessions any representation in Parliament, much less equality.

    Compelling evidence supports the effectiveness of the reduction of total and LDL cholesterol (TC and LDL-C) in primarily preventing cardiovascular events, within the framework of life-long prevention programs mainly consisting in lifestyle changes. Pharmacological treatment should be introduced when lifestyle changes, including use of nutraceuticals, have failed. ESC\\/EAS guidelines list a number of nutraceutical compounds and functional foods which have been individually studied in randomized, controlled clinical trials (RCTs). To date only a proprietary formulation of three naturally occurring substances with putative complementary lipid-lowering properties - red yeast rice, policosanol and berberine - combined with folic acid, astaxanthin, and coenzyme Q10 (Armolipid Plus(®)) has been extensively investigated in several RCTs, 7 of which were placebo-controlled, 2 were ezetimibe comparators and 4 were "real life" studies comparing diet and Armolipid Plus to diet alone. The trials included mostly patients with mild to moderate dyslipidemia, treated for 6-48 weeks. The trials also included special populations and patients in whom statins were contraindicated or who could not tolerate them. Armolipid Plus has proved to be able to achieve significant reductions in TC (11-21%) and in LDL-C (15-31%) levels, which is equivalent to expectations from low dose statins. In patients intolerant to statins, who do not achieve their therapeutic target with ezetimibe, Armolipid Plus can achieve a further 10% improvement in TC and LDL-C. The safety and tolerability of Armolipid Plus were excellent, thought likely due to the intentional combination of low doses of its active ingredients: low enough not to be associated with untoward effects, but high enough to exert therapeutic effects in combination with other complementary substances. Consequently, in the event of intolerance to statins, Armolipid Plus offers an effective alternative, which is devoid of the safety risks

    The aquifer system at the Gorleben site was chosen as the case for verifying the applicability of laboratory data describing the solubility and sorption of radionuclides to the conditions at the real site. For this purpose, the data derived from geochemical models, predicting the distribution of the chemical species in the ground water, were compared with the experimental data obtained by spectroscopic speciation on site. This procedure allows to perform a validation of the geochemical model and of the data underlying the model. The study reported encompasses work for establishing or supplementing the thermodynamic database, an analysis of site-specific data, as e.g. on the formation of colloids, as well as the comparative analyses for ascertainment of applicability. Upon compilation and critical review of data found in the literature, the thermodynamic regime of geochemically relevant reactions of selected actinide ions was examined, leading to data describing the thermodynamics of the hydrolysis of (Cm (III), Pu (IV), Np (V) and Pu (VI)), or the complexation with carbonate (Am (III), Cm (III) and Np (V)). The data are obtained by pH-dependent solubility measurements, or derived by spectroscopic speciation. In addition, a thermodynamic model was established which gives a quantitative description of the geochemically relevant complexation with humic substances (Am (III), Cm (III), and Np (V)). It was found that the increase of the redox potiental, induced in strongly salty solutions by α-radiolysis, was worth to be studied for its effect on the stabilisation of Pu (VI). Solubility measurements detected the formation of hypochlorito-complexes and of metastable, polynuclear Pu (VI)-species, which was verified by spectroscopy. (orig.)

    Hydrogeological site characterization for deep geological high level and intermediate level long lived radioactive waste repository cover a large time scale needed for safety analysis and calculation. Hydrogeological performance of a site relies also on the effects of geodynamic evolution as tectonic uplift, erosion/sedimentation and climate including glaciation on the groundwater flow and solute and heat transfer. Thermo-Hydro-Mechanical model of multilayered aquifer system of Paris Basin is developed to reproduce the present time flow and the natural tracer (Helium) concentration profiles based on the last 2 Ma of geodynamic evolution. Present time geological conceptual model consist of 27 layers at Paris Basin (Triassic-Tertiary) with refinement at project site scale (29 layers from Triassic to Portlandian). Target layers are the clay host formation of Callovo-Oxfrodian age (160 Ma) and the surrounding aquifer layers of Oxfordian and Dogger. Modelled processes are: groundwater flow, heat and solutes (natural tracers) transport, freezing and thawing of groundwater (expansion and retreat of permafrost), deformation of the multilayered aquifer system induced by differential tectonic uplift and the hydro-mechanical stress effect as caused by erosion of the outcropping layers. Numerical simulation considers a period from 2 Ma BP and up to the present. Transient boundary conditions are governed by geodynamic processes: (i) modification of the geometry of the basin and (ii) temperatures along the topography will change according to a series of 15 identical climate cycles with multiple permafrost (glaciation) periods. Numerical model contains 71 layers and 18 million cells. The solution procedure solves three coupled systems of equations, head, temperature and concentrations, by the use of a finite difference method, and by applying extensive parallel processing. The major modelling results related to the processes of importance for site characterization as hydraulic

    Full Text Available Many discussions surrounding environmental ethics and spirituality revolve aroundenchantment and place. Such notions are inherently marked by transcendentunderstandings of “religion” and “nature.” This article suggests that these transcendentunderstandings could be problematic in an era of globalization marked by movement andchange. Using the work of postmodern thinkers to destabilize foundational concepts of“Nature,” as well as the sacred, this article argues for fashioning a planetary ethic thatpays attention to aesthetics of movement and change, moving environmental ethics froma discussion about place to a discussion about pace.

    The proposed action is to issue a renewal to the full-term Special Nuclear Material License No. SNM-414 (Docket No. 70-364) authorizing the Nuclear Material Division of the Babcock and Wilcox Company (BandW) to operate nuclear-fuel-fabrication facilities located in Leechburg, Pennsylvania. The plutonium fuel facility is presently being used to fabricate fuel for the fast test reactor under construction at the Hanford Reservation near Richland, Washington. Implicit in Sections 70.22 and 70.23 of 10CFR70 is a requirement that existing plutonium fabrication plants be examined with the objective of improving, to the extent practicable, their abilities to withstand adverse natural phenomena without loss of capability to protect the public. In accordance with these regulations, an analysis was initiated of the effects of natural phenomena on the BandW Plutonium Fabrication Plant. Following completion of the analysis, a condensation was prepared of the effects of natural phenomena on the facility

    Diels-Alder cycloaddition between cyclopentadiene and p -benzoquinone has been studied in the confined space of a pure silica zeolite Beta and the impact on reaction rate due to the concentration effect within the pore and diffusion limitations are discussed. Introduction of Lewis or Brønsted acid sites on the walls of the zeolite strongly increases the reaction rate. However, contrary to what occurs with mesoporous molecular sieves (MCM-41), Beta zeolite does not catalyse the retro-Diels-Alder reaction, resulting in a highly selective catalyst for the cycloaddition reaction.

    Potential environmental consequences in terms of radiation dose to people are presented for postulated radionuclide releases caused by severe natural phenomena at the Battelle Memorial Institute Columbus Laboratories JN-1b Building at the West Jefferson site. The severe natural phenomena considered are earthquakes, tornadoes, and high straight-line winds. Maximum radioactive material deposition values are given for significant locations around the site. All important potential exposure pathways are examined. The most likely 50-year committed dose equivalents are given for the maximum-exposed individual and the population within a 50-mile radius of the plant. The maximum radioactive material deposition values likely to occur offsite are also given. The most likely calculated 50-year collective committed dose equivalents are all much lower than the collective dose equivalent expected from 50 years of exposure to natural background radiation and medical x-rays. The most likely maximum residual plutonium contamination estimated to be deposited offsite following the events are well below the Environmental Protection Agency's (EPA) proposed guideline for plutonium in the general environment of 0.2 μCi/m 2 . The likely maximum residual contamination from beta and gamma emitters are far below the background produced by fallout from nuclear weapons tests in the atmosphere

    The determination of the nature and structure of surface sites after chemical modification of large surface area oxides such as silica is a key point for many applications and challenging from a spectroscopic point of view. This has been, for instance, a long-standing problem for silica reacted with alkylaluminum compounds, a system typically studied as a model for a supported methylaluminoxane and aluminum cocatalyst. While 27Al solid-state NMR spectroscopy would be a method of choice, it has been difficult to apply this technique because of large quadrupolar broadenings. Here, from a combined use of the highest stable field NMR instruments (17.6, 20.0, and 23.5 T) and ultrafast magic angle spinning (>60 kHz), high-quality spectra were obtained, allowing isotropic chemical shifts, quadrupolar couplings, and asymmetric parameters to be extracted. Combined with first-principles calculations, these NMR signatures were then assigned to actual structures of surface aluminum sites. For silica (here SBA-15) reacted with triethylaluminum, the surface sites are in fact mainly dinuclear Al species, grafted on the silica surface via either two terminal or two bridging siloxy ligands. Tetrahedral sites, resulting from the incorporation of Al inside the silica matrix, are also seen as minor species. No evidence for putative tri-coordinated Al atoms has been found. © 2012 American Chemical Society.

One major concern has emerged due to the possible contamination of groundwater from unconventional oil and natural gas extraction activities. Recent studies have been performed to understand if these activities are causing groundwater contamination, particularly with respect to exogenous hydrocarbons and volatile organic compounds. The impact of contaminants on microbial ecology is an area to be explored as alternatives for water treatment are necessary. In this work, we identified cultivable organic-degrading bacteria in groundwater in close proximity to unconventional natural gas extraction. Pseudomonas stutzeri and Acinetobacter haemolyticus were identified using matrix-assisted laser desorption/ionization-time-of-flight-mass spectrometry (MALDI-TOF MS, which proved to be a simple, fast, and reliable method. Additionally, the potential use of the identified bacteria in water and/or wastewater bioremediation was studied by determining the ability of these microorganisms to degrade toluene and chloroform. In fact, these bacteria can be potentially applied for in situ bioremediation of contaminated water and wastewater treatment, as they were able to degrade both compounds.

    Full Text Available Many rural coastal Mediterranean areas suffer from great anthropomorphic pressure. This is due to intensive agriculture, and construction for residential, tourism and industrial uses. The present work investigates the idea of using a landscape project in the Gulf of Gela in South Sicily to recover the dunes and the area behind them. The method used is based on the literature and will evaluate and interpret the dynamics of the landscape, so as to draw up a landscape plan, which can be used to help sustain the assets of the area, in a way, which is compatible with conserving nature. This method was tested in the LIFE11-Leopoldia project, funded by the European Union. The results of the study form part of the landscape project. This project is aimed at connecting the different productive zones in the area, protecting the natural environments and the rural historical patrimony, through combining the modern road networks with the older slower, historic infrastructure. Three different levels of landscape management are proposed: total protection (the dunes, high-level protection (the area behind the dunes where traditional agriculture is practised, buffer areas and ecological connecting areas, medium levels of protection (sustainable agriculture, green connections and ecological corridors. The key aims of the project are as follows: transversality - repairing the agricultural fabric and the relationship between the land and the sea; sustainability - recovering the environmental system and traditional activities; flexibility - agriculture with only minor environmental impact.

    This study deals with effects of extreme climatic events in France on perenniality of radioactive or toxic waste disposal coverings or of tailing storage barriers. Three phenomena are quantified: erosion or scraping produced by storm showers, ground freezing depth caused by harsh winters and ground drying resulted from arid summers. To quantify this phenomena, we need statistical evaluation of the climatic events (erosivity of rain showers, frost severity index, drought severity indices), a study of the soil characteristics (petrography, thermal and hydraulic properties) and numeric models of soils (finite elements or finite differences methods). Last but not least, each method is applied to French sites chosen for their climate and their proximity to real or possible storage. Therefore, we show critical parameters for the design of waste disposal covering which takes into account extreme climatic events. (author)

  3. The location and nature of general anesthetic binding sites on the active conformation of firefly luciferase; a time resolved photolabeling study.

    Directory of Open Access Journals (Sweden)

    Sivananthaperumal Shanmugasundararaj

    Full Text Available Firefly luciferase is one of the few soluble proteins that is acted upon by a wide variety of general anesthetics and alcohols; they inhibit the ATP-driven production of light. We have used time-resolved photolabeling to locate the binding sites of alcohols during the initial light output, some 200 ms after adding ATP. The photolabel 3-azioctanol inhibited the initial light output with an IC50 of 200 µM, close to its general anesthetic potency. Photoincorporation of [(3H]3-azioctanol into luciferase was saturable but weak. It was enhanced 200 ms after adding ATP but was negligible minutes later. Sequencing of tryptic digests by HPLC-MSMS revealed a similar conformation-dependence for photoincorporation of 3-azioctanol into Glu-313, a residue that lines the bottom of a deep cleft (vestibule whose outer end binds luciferin. An aromatic diazirine analog of benzyl alcohol with broader side chain reactivity reported two sites. First, it photolabeled two residues in the vestibule, Ser-286 and Ile-288, both of which are implicated with Glu-313 in the conformation change accompanying activation. Second, it photolabeled two residues that contact luciferin, Ser-316 and Ser-349. Thus, time resolved photolabeling supports two mechanisms of action. First, an allosteric one, in which anesthetics bind in the vestibule displacing water molecules that are thought to be involved in light output. Second, a competitive one, in which anesthetics bind isosterically with luciferin. This work provides structural evidence that supports the competitive and allosteric actions previously characterized by kinetic studies.

    In conjunction with RCRA site corrective action at an active wood preserving facility, a risk-based site closure strategy was developed and incorporated the performance of a dense non-aqueous phase liquid (DNAPL) source recovery remedy, a monitored natural attenuation (MNA) remedy for dissolved phase groundwater, and institutional controls. Innovative creosote DNAPL source recovery has been undertaken at the Site since 1998. Pooled creosote DNAPL is present 90 feet below ground within a transmissive sand and gravel aquifer with a saturated thickness of approximately 80 feet. The creosote DNAPL source is situated on the property boundary of the site and has generated a 1/2 mile off-site dissolved phase plume, creating significant NAPL management and remedial technology verification issues. To date, over 120,000 gallons of creosote DNAPL have been recovered from the subsurface utilizing a modified circulation well technology. A mass discharge flux protocol was developed to serve as a major performance metrics for the continuation of source removal efforts and to support the application of monitored natural attenuation as an associated remedial technology for groundwater. The mass removal success has supported the MNA remedy for dissolved phase groundwater and the associated development of institutional controls. The enacted site management strategy outlines the current and future risk management activities for the Site and represents an appropriate site closure strategy for the Site. (authors)

This bacterium is normally a benign swine commensal but may become a deadly pathogen upon penetration into multiple tissues, contributing to severe lesions in swine. We have established a successive natural transformation-based markerless mutation system in this species. However, the two-step mutation system requires screening of natural competent cells, and cannot delete genes which regulate natural competence per se. In this study, we successfully obtained streptomycin-resistant derivatives from H. parasuis wild type strain SC1401 by using ethyl methane sulfonate (EMS, CH3SO2OC2H5. Upon sequencing and site-directed mutations, we uncovered that the EMS-induced point mutation in rpsL at codon 43rd (AAA → AGA; K43R or at 88th (AAA → AGA; K88R confers a much higher streptomycin resistance than clinical isolates. We have applied the streptomycin resistance marker as a positive selection marker to perform homologous recombination through conjugation and successfully generated a double unmarked in-frame targeted mutant 1401D88△tfox△arcA. Combined with a natural transformation-based knockout system and this genetic technique, multiple deletion mutants or attenuated strains of H. parasuis can be easily constructed. Moreover, the mutant genetic marker rpsL and streptomycin resistant phenotypes can serve as an effective tool to select naturally competent strains, and to verify natural transformation quantitatively.

    A geophysical survey was carried out in the Petrified Forest of Evros, the northernmost regional unit of Greece. This collection of petrified wood has an age of approximately 35 million years and it is the oldest in Greece (i.e., older than the well-known Petrified Forest of Lesvos island located in the North Aegean Sea and which is possibly the largest of the petrified forests worldwide). Protection, development and maintenance projects still need to be carried out at the area despite all fears regarding the forest's fate since many petrified logs remain exposed both in weather conditions - leading to erosion - and to the public. This survey was conducted as part of a more extensive framework regarding the development and protection of this natural monument. Geophysical surveying has been chosen as a non-destructive investigation method since the area of application is both a natural ecosystem and part of cultural heritage. Along with electrical resistivity tomography (ERT), ground penetrating radar (GPR) surveys have been carried out for investigating possible locations of buried fossilized tree trunks. The geoelectrical sections derived from ERT data in combination with the GPR profiles provided a broad view of the subsurface. Two and three dimensional subsurface geophysical images of the surveyed area have been constructed, pointing out probable locations of petrified logs. Regarding ERT, petrified trunks have been detected as high resistive bodies, while lower resistivity values were more related to the surrounding geological materials. GPR surveying has also indicated buried petrified log locations. As these two geophysical methods are affected in different ways by the subsurface conditions, the combined use of both techniques enhanced our ability to produce more reliable interpretations of the subsurface. After the completion of the geophysical investigations of this first stage, petrified trunks were revealed after a subsequent excavation at indicated

    In the Middle East, the future of nuclear nonproliferation depends on progress towards the settlement of the Arab-Israeli conflict as much as on proliferation developments in those regional states that are currently outside the peace process. This article describes how the present situation is a mix of good and bad news. The good news is that both moderate Arab states and Israel share a genuine concern about nuclear proliferation and the need to deal with it on a regional basis. Furthermore, in conjunction with the bilateral peace talks, there is now a regional forum--the Multilateral Working Group on Regional Security and Arms Control--to discuss these issues. The bad news is that the region's most determined proliferators, Iran and Iraq, are not parties to the forum. This article contains proposals for Middle East arms control measures and discusses the likelihood that a given measure would be successful. Essentially, the author believes that minimization of the dangers of nuclear proliferation in the Middle East will require that the deep political conflict underlying the incentive for proliferation be addressed

  12. Sacred radical of psychiatry.

    At least a dozen articles in this journal have referred directly to the psychiatry of Thomas Szasz, even favourably on occasions. Szasz makes no distinction between the occupational statuses of mental health workers and so his work is relevant to nurses. Szasz's central claims take on renewed vitality given recent developments in forensic care, especially in Britain. In this article, I criticize Szasz's rationale of what constitutes illness as opposed to disease. In addition, I question - in a nuanced way - his views on custodial psychiatry and his use of history to bolster his clams. I also comment on recent developments in biological research and their implications for diagnosing schizophrenia: further, I link the question of such diagnoses to Szasz's assertion that private contracts are the definitive test of what counts as mental illness. Lastly, I ask if improvements in mental health care contradict Szaszian criticisms and/or his seeming inability/unwillingness to acknowledge such changes.

    During the colonial period, the indigenous saraguros maintained their traditions, knowledge, and practices to restore and preserve the health of their members. Unfortunately, many of their practices and medicinal resources have not been documented. In this study, we sought to document the traditional healers' (yachakkuna saraguros) knowledge about medicinal and psychoactive plants used in the mesas and in magical-religious rituals. The study was conducted under a technical and scientific cooperation agreement between the Universidad Técnica Particular de Loja (UTPL), the Dirección Provincial de Salud de Loja (DPSL), and the Saraguro Healers Council (Consejo de Sanadores de Saraguro). For the present study, the DPSL and Saraguro Healers Council selected the 10 yachakkuna most recognized for their knowledge and their use of sacred and psychoactive species. Ten interviews with the selected yachakkuna were conducted between 2010 and 2011 to ascertain how the Saraguro traditional healing system is structured and to obtain a record of the sacred and medicinal plant species used to treat supernatural diseases and for psychoactive purposes. The present study describes the traditional health system in the Saraguro indigenous community located in southern Ecuador. It also describes the main empirical methods used to diagnose diseases: direct physical examination of the patient, observation of the patient's urine, documentation of the patient's pulse, limpia, palpation and visionary methods, including supernatural diseases (susto, vaho de agua, mal aire, mal hecho, shuka) and reports of the use of sacred and medicinal psychoactive plants, such as the San Pedro cactus (Echinopsis pachanoi), wandug (Brugmansia spp.), and tobacco (Nicotiana spp.). This study also describes the rituals (limpia, soplada) employed by the Saraguro yachakkuna to treat supernatural diseases. Finally, we report on the main plants used during limpia in the Saraguro community. The current traditional

    Full Text Available Cet article étudie les mythes historiques concernant Sayrām, une petite ville du sud de l'actuel Kazakhstan, cas exemplaire de concepts indigènes d'identité communautaire en Asie centrale pré-soviétique. Ces traditions sont conservées dans un ensemble de travaux en turc, sous le titre générique de « Histoire de Sayrām », qui combine une « histoire sacrée » de la ville avec une « géographie sacrée » sous la forme d'un catalogue de mausolées locaux ; ces deux composantes situent ainsi Sayrām à la fois dans le temps et dans l'espace, à l'intérieur d'un univers sacré défini en tant qu'islamique. Elles offrent une vision de la participation de cette ville à un cadre historique déterminé par l'hommage sanctificateur du Prophète Muhammad à Sayrām, et une affirmation de la présence continue et de la protection, à travers leurs mausolées, d'une multitude de saints musulmans (comprenant aussi bien des personnages purement locaux que d'autres bien connus dans le folklore islamique. Ces ouvrages, compilés vraisemblablement au XVIIIe siècle et répandus très largement dans la seconde moitié du XIXe siècle, reflètent souvent d'anciennes traditions narratives évocatrices du rôle de Sayrām au début de l'islamisation de l'Asie centrale. Mais elles montrent également l'importance capitale de la définition par la religion des identités locales et régionales, au sein de la population sédentaire d'Asie centrale, avant les changements induits par la conquête russe, l'établissement du pouvoir soviétique et la formulation des nouvelles identités « nationales » qui perdurent aujourd'hui.

    Two electroluminescent polymer matrices poly(N-vinylcarbazole) (PVK) and PVK with 40 wt% of 2-tert-butylphenyl-5-biphenyl-1,3,4-oxadiazole (PBD) were studied using spectrally resolved thermoluminescence (SRTL) in the temperature range 15-325 K. The comparison of the SRTL results with the electroluminescence (EL) spectra has allowed identification of the localized (trapping) sites and the radiative recombination centres present in the investigated matrices. In the neat PVK films deep traps with a depth about 200 meV, related to triplet excimers dominate, while in the PVK-PBD (40 wt%) blend films the traps that are related to triplet exciplexes formed by the carbazole groups and the PBD molecules dominate. Depth of the traps in the PVK-PBD blend is somewhat lower than that in the neat PVK. An analysis of the EL spectra shows that in the PVK and in the PVK-PBD blend the dominant radiative centres are singlet excimers and singlet exciplexes, respectively. However, in the neat PVK some contributions of the triplet monomer and the triplet excimer states in the EL were also detected.

    To help confirm correct functioning of an epithermal neutron sonde, we measured tightly bonded water content of selected Nevada Test Site (NTS) drill holes. Tuff and alluvium samples were dried overnight at 105 0 C. The samples were then heated for 45 min in a split tube furnace at 700 0 C. The water that came off due to this heating was collected and the amount recorded. The error in this procedure is +- 0.59 wt %. Total water can be calculated for samples from analyses of free and tightly bonded water contents. The maximum error in this calculation is equivalent to the error in determining the more tightly bonded water. Average total water content values have been assigned to geologic units. These values, in weight fraction, are alluvium 0.14 +- .05 and tuff 0.19 +- .04. Further division of the tuff gives values of Rainier Mesa 0.15 +- .01, Paintbrush 0.18 +- .03, Tunnel Beds 0.20 +- .04, and Grouse Canyon 0.29 +- .02. Statistically significant differences occur between the tuff and alluvium. Within the tuffs, these differences also occur between Grouse Canyon, Rainier Mesa, and Paintbrush/Tunnel Beds. Paintbrush and Tunnel Beds cannot be distinguished by this method

During the one-year period of this study, we captured 3,104 phlebotomine sand flies belonging to sixteen Lutzomyia species. In addition to identifying incriminated or suspected vectors of ACL with DNA of the etiological agent of AVL and vice versa, we also detected Leishmania DNA in unexpected Lutzomyia species. The expressive presence of vectors and natural Leishmania infection indicates favorable conditions for the spreading of leishmaniases in the vicinity of the Serra do Cipó National Park.

    Full Text Available Overexpression of the amyloid precursor protein (APP and the hyperphosphorylation of the tau protein are vital in the understanding of the cause of Alzheimer’s disease (AD. As a consequence, regulation of the expression of both APP and tau proteins is one important approach in combating AD. The APP and tau proteins can be targeted at the levels of transcription, translation and protein structural integrity. This paper reports the utilization of a bi-cistronic vector containing either APP or tau internal ribosome entry site (IRES elements flanked by β-galactosidase gene (cap-dependent and secreted alkaline phosphatase (SEAP (cap-independent to discern the mechanism of action of memantine, an N-methyl-d-aspartate (NMDA receptor antagonist. Results indicate that memantine could reduce the activity of both the APP and tau IRES at a concentration of ~10 μM (monitored by SEAP activity without interfering with the cap-dependent translation as monitored by the β-galactosidase assay. Western blot analysis of the tau protein in neuroblastoma (N2A and rat hippocampal cells confirmed the halting of the expression of the tau proteins. We also employed this approach to identify a preparation named NB34, extracts of Boussingaultia baselloides (madeira-vine fermented with Lactobacillus spp., which can function similarly to memantine in both IRES of APP and Tau. The water maze test demonstrated that NB34 could improve the spatial memory of a high fat diet induced neurodegeneration in apolipoprotein E-knockout (ApoE−/− mice. These results revealed that the bi-cistronic vector provided a simple, and effective platform in screening and establishing the mechanistic action of potential compounds for the treatment and management of AD.

    Laboratory experiments suggest that calcifying developmental stages of marine invertebrates may be the most ocean acidification (OA)-sensitive life-history stage and represent a life-history bottleneck. To better extrapolate laboratory findings to future OA conditions, developmental responses in sea urchin embryos/larvae were compared under ecologically relevant in situ exposures on vent-elevated pCO 2 and ambient pCO 2 coral reefs in Papua New Guinea. Echinometra embryos/larvae were reared in meshed chambers moored in arrays on either venting reefs or adjacent non-vent reefs. After 24 and 48 h, larval development and morphology were quantified. Compared with controls (mean pH (T) = 7.89-7.92), larvae developing in elevated pCO 2 vent conditions (pH (T) = 7.50-7.72) displayed a significant reduction in size and increased abnormality, with a significant correlation of seawater pH with both larval size and larval asymmetry across all experiments. Reciprocal transplants (embryos from vent adults transplanted to control conditions, and vice versa) were also undertaken to identify if adult acclimatization can translate resilience to offspring (i.e. transgenerational processes). Embryos originating from vent adults were, however, no more tolerant to reduced pH. Sea temperature and chlorophyll-a concentrations (i.e. larval nutrition) did not contribute to difference in larval size, but abnormality was correlated with chlorophyll levels. This study is the first to examine the response of marine larvae to OA scenarios in the natural environment where, importantly, we found that stunted and abnormal development observed in situ are consistent with laboratory observations reported in sea urchins, in both the direction and magnitude of the response. © 2016 The Author(s).
