    Pena, Manuel Arturo Izquierdo

    2008-01-01

    The aim of this project is to review and expand upon the model proposed by Father Jos\\'e Domingo Duquesne de la Madrid (1745-1821) regarding the calendar of the ancient Muisca culture of the central Colombia. This model was dismissed by scholars in the late 19th century, calling it just a simple invention of a clergyman; however, a detailed analysis of Duquesne's work shows that his interpretation of the timekeeping system was based on information given to him by indigenous informers. Based on his work, we can be derive somewhat indirectly, some aspects of the calendar that apparently were not understood by the priest. This confirms that such a system was not his own invention. Ethnohistorical and archaeological evidence provides support for Duquesne's calendar model. Massive Muisca ceremonies described by 16th century Spanish chroniclers, is examined and; the occurrence of such ceremonies seem to match the astronomical cycle of conjunctions of the planets Jupiter and Saturn, wich also agrees with the 60-year...

    Full Text Available Background . Alaska Native people are disproportionately impacted by tobacco-related diseases in comparison to non-Native Alaskans. Design. We used Alaska's Behavioral Risk Factor Surveillance System (BRFSS to describe tobacco use among more than 4,100 Alaska Native adults, stratified by geographic region and demographic groups. Results . Overall tobacco use was high: approximately 2 out of every 5 Alaska Native adults reported smoking cigarettes (41.2% and 1 in 10 reported using smokeless tobacco (SLT, 12.3%. A small percentage overall (4.8% reported using iq'mik, an SLT variant unique to Alaska Native people. When examined by geographic region, cigarette smoking was highest in remote geographic regions; SLT use was highest in the southwest region of the state. Use of iq'mik was primarily confined to a specific area of the state; further analysis showed that 1 in 3 women currently used iq'mik in this region. Conclusion . Our results suggest that different types of tobacco use are epidemic among diverse Alaska Native communities. Our results also illustrate that detailed analysis within racial/ethnic groups can be useful for public health programme planning to reduce health disparities.

    The exact timing, route, and process of the initial peopling of the Americas remains uncertain despite much research. Archaeological evidence indicates the presence of humans as far as southern Chile by 14.6 thousand years ago (ka), shortly after the Pleistocene ice sheets blocking access from eastern Beringia began to retreat. Genetic estimates of the timing and route of entry have been constrained by the lack of suitable calibration points and low genetic diversity of Native Americans. We sequenced 92 whole mitochondrial genomes from pre-Columbian South American skeletons dating from 8.6 to 0.5 ka, allowing a detailed, temporally calibrated reconstruction of the peopling of the Americas in a Bayesian coalescent analysis. The data suggest that a small population entered the Americas via a coastal route around 16.0 ka, following previous isolation in eastern Beringia for ~2.4 to 9 thousand years after separation from eastern Siberian populations. Following a rapid movement throughout the Americas, limited gene flow in South America resulted in a marked phylogeographic structure of populations, which persisted through time. All of the ancient mitochondrial lineages detected in this study were absent from modern data sets, suggesting a high extinction rate. To investigate this further, we applied a novel principal components multiple logistic regression test to Bayesian serial coalescent simulations. The analysis supported a scenario in which European colonization caused a substantial loss of pre-Columbian lineages. PMID:27051878

    The Balkans is a biogeographically highly diverse region and a worldwide hotspot of endemic freshwater diversity. A substantial part of this diversity is attributed to well recognized and potential ancient lakes in its southwestern part. However, despite considerable research efforts, faunal relationships among those lakes are not well understood. Therefore, genetic information from native representatives of the mussel genus Dreissena is here used to test the biogeographical zonation of the southwestern Balkans, to relate demographic changes to environmental changes, to assess the degree of eco-insularity, to reconstruct their evolutionary history, and to explore the potential of native taxa for becoming invasive. Phylogeographical and population genetic analyses indicate that most studied populations belong to two native species: D. presbensis (including the distinct genetic subgroup from Lake Ohrid, "D. stankovici") and D. blanci. In addition, the first confirmed record of invasive D. polymorpha in the southwestern Balkan is presented. The distribution of native Dreissena spp. generally coincides with the biogeographical zonations previously suggested based on fish data. However, there is disagreement on the assignment of the ancient lakes in the area to respective biogeographical regions. The data for Lake Ohrid are not conclusive. A closer biogeographical connection to lakes of the Vardar region and possibly the northern Ionian region is, however, suggested for Lake Prespa. The reconstruction of the evolutionary history of Dreissena spp. suggests that populations underwent demographic and spatial expansions in the recent past. Expansions started around 320 000-300 000 years ago in "D. stankovici", 160 000-140 000 years ago in D. blanci, and 110 000-70 000 years ago in D. presbensis. These time frames are discussed within the context of available paleogeological data for lakes Ohrid and Prespa. It is suggested that regional environmental changes may have had

Disease-specific Alaska Native mortality rates have been undergoing change. Objective . This article reports recent mortality data (2004–2008 for Alaska Native/American Indian (AN/AI people, comparing mortality rates to US white rates and examines changes in mortality patterns since 1980. Design . We used death record data from the state of Alaska, Department of Vital Statistics and SEER*Stat software from the National Cancer Institute to calculate age-adjusted mortality rates. Results . Annual age-adjusted mortality from all-causes for AN/AI persons during the period 2004–2008 was 33% higher than the rate for US whites (RR=1.33, 95% CI 1.29–1.38. Mortality rates were higher among AN/AI males than AN/AI females (1212/100,000 vs. 886/100,000. Cancer remained the leading cause of death among AN/AI people, as it has in recent previous periods, with an age-adjusted rate of 226/100,000, yielding a rate ratio (RR of 1.24 compared to US whites (95% CI 1.14–1.33. Statistically significant higher mortality compared to US white mortality rates was observed for nine of the ten leading causes of AN/AI mortality (cancer, unintentional injury, suicide, alcohol abuse, chronic obstructive pulmonary disease [COPD], cerebrovascular disease, chronic liver disease, pneumonia/influenza, homicide. Mortality rates were significantly lower among AN/AI people compared to US whites for heart disease (RR=0.82, the second leading cause of death. Among leading causes of death for AN/AI people, the greatest disparities in mortality rates with US whites were observed in unintentional injuries (RR=2.45 and suicide (RR=3.53. All-cause AN/AI mortality has declined 16% since 1980–1983, compared to a 21% decline over a similar period among US whites. Conclusion .

    Full Text Available Background. Several studies have shown that Alaska Native people have higher smoking prevalence than non-Natives. However, no population-based studies have explored whether smoking-related knowledge, attitudes, and behaviours also differ among Alaska Native people and non-Natives. Objective. We compared current smoking prevalence and smoking-related knowledge, attitudes, and behaviour of Alaska Native adults living in the state of Alaska with non-Natives. Methods. We used Alaska Behavioral Risk Factor Surveillance System data for 1996 to 2010 to compare smoking prevalence, consumption, and cessation- and second-hand smoke-related knowledge, attitudes, and behaviours among self-identified Alaska Native people and non-Natives. Results. Current smoking prevalence was 41% (95% CI: 37.9%–44.4% among Alaska Native people compared with 17.1% (95% CI: 15.9%–18.4% among non-Natives. Among current every day smokers, Alaska Natives were much more likely to smoke less than 10 cigarettes per day (OR=5.0, 95% CI: 2.6–9.6 than non-Natives. Compared with non-Native smokers, Alaska Native smokers were as likely to have made a past year quit attempt (OR=1.4, 95% CI: 0.9–2.1, but the attempt was less likely to be successful (OR=0.5, 95% CI: 0.2–0.9. Among current smokers, Alaska Natives were more likely to believe second-hand smoke (SHS was very harmful (OR=4.5, 95% CI: 2.8–7.2, to believe that smoking should not be allowed in indoor work areas (OR=1.9, 95% CI: 1.1–3.1 or in restaurants (OR=4.2, 95% CI: 2.5–6.9, to have a home smoking ban (OR=2.5, 95% CI: 1.6–3.9, and to have no home exposure to SHS in the past 30 days (OR=2.3, 95% CI: 1.5–3.6 than non-Natives. Conclusion. Although a disparity in current smoking exists, Alaska Native people have smoking-related knowledge, attitudes, and behaviours that are encouraging for reducing the burden of smoking in this population. Programs should support efforts to promote cessation, prevent relapse

    Simple exposure to Western goods may not be a sufficient explanation of why isolated village communities increase their participation in external market economies. The degree of market participation by four native villages in central Brazil is related to the difficulty of making a living from slash-and-burn subsistence agriculture as measured by the ratio of labor input to food output.

    Full Text Available Objectives. Members of racially and ethnically diverse groups have been persistently underrepresented in biomedical research in general, possibly due to mistrust with the medical and research community. This article describes the perceptions, understandings, and expectations of Alaska Native people about research involving the collection and storage of biological specimens. Study design. Stratified focus groups. Methods. Twenty-nine focus groups with Alaska Native people (n = 178 were held in 14 locations using a semi-structured moderator guide. ATLAS.ti was used for thematic analysis through iterative readings and coding. Alaska Native peoples’ perceptions, understandings, and expectations of researcher beneficence, informed consent processes, and provision of research findings were elicited. Results and conclusions. Alaska Native people desired extensive disclosure of information beyond that typically provided in consent and results dissemination processes. Information germane to the motivation and intent of researchers and specifics of specimen storage and destruction were specifically requested. A clear and extensive process of informed consent and continued improvements in sharing results may enhance the transparency of research intent, conduct, and use of obtained results among Alaska Native people. Meeting expectations may improve relationships between researchers and the Alaska Native population which could result in increased research participation. Our findings offer a guide for researchers and communities when planning and implementing research with biological specimens.

    To compare the utilization of health care resources (drug prescriptions, hospital admissions and health care services) by immigrant versus native elderly people (65 years or more), by using administrative database of the Lombardy Region. For each immigrant (an older people born out of Italy), one person born in Lombardy (native) was randomly selected and matched by age, sex and general practitioner. The 25,508 immigrants selected were less prescribed with at least one drug (OR 0.72, 95 % CI 0.67-0.76) and had a lesser use of health care services (OR 0.79, 95 % CI 0.75-0.84) than natives. No statistically significant differences were found for hospital admission rates (OR 0.99, 95 % CI 0.99-1.04). A lower rate of health care resource utilization was observed in elderly immigrants who had been living in the host region for as many as 10 years. PMID:25576178

    Nysa, one of the most important cities of Caria in Hellenistic and Roman period, is located on the highway connecting Aydin (ancient name Tralleis) and Denizli, at about three kilometres northwest of Sultanhisar in western Anatolia of Turkey. The archaeological remains of Nysa are located on the slopes on the side of the stream called Tekkecik. The buildings, streets and public squares of the ancient city were supported by vaulted substructures adapted to the topographic conditions. As to the foundation of the city, Strabo relates that three brothers named Athymbros, Athymbrados, and Hydrelos came from Lakedaimon to Caria, and founded there three cities named after themselves. The small rock samples from the building of theatre, stadium, basement of agora and tomb were collected and determined under polarized microscope and confocal Raman spectroscopy to find out the native of these rock sources. The results of these studies reveal that the main rocks of these structures are composed from white colour marble. These marbles have granoblastic texture and are composed of mainly pressure twinned calcite as coarse grain size. The confocal Raman specroscopical studies of reveal that the marble building stone of Nysa city are mainly obtained from Jurassic Cretaceous of Western Anatolia marble.

    In 1987, wooden slips named Zhi Chigu Fang (Chigu Decoction) were discovered on the site of the Ancient People's Dike in Zhangjiajie, Hunan Province. 15 drugs with dosage were listed on the front of the wooden slip and processing on the reverse side. Though there are two academic opinions about Chigu Decoction neither of them is convincing. Zhi means treatment and Chigu is the name of an ancient exogenous febrile disease with the symptoms of aversion to cold, fever, headache and neck pain, ankylosis, cough and asthma or cold pain in the gastric area and diarrhea. Chi is a descriptive word describing the appearance of exogenous febrile fever. PMID:22169493

    2014-08-01

    Fish are a healthy source of protein and nutrients, but contaminants in fish may provide health risks. Determining the risk from contaminants in fish requires site-specific information on consumption patterns. We examine consumption rates for resident and expatriates in the Jeddah region of Saudi Arabia, by species of fish and fishing location. For Saudis, 3.7% of males and 4.3% of females do not eat fish; for expatriates, the percent not eating fish is 6.6% and 6.1% respectively. Most people eat fish at home (over 90%), and many eat fish at restaurants (65% and 48%, respectively for Saudis and expatriates). Fish eaten at home comes from local fish markets, followed by supermarkets. Saudis included fish in their diets at an average of 1.4±1.2 meals/week at home and 0.8±0.7 meals/week at restaurants, while expats ate 2.0±1.7 meals/week at home and 1.1±1.1 meals/week in restaurants. Overall, Saudis ate 2.2 fish meals/week, while expats ate 3.1 meals/week. Grouper (Epinephelus and Cephalopholis) were eaten by 72% and 60% respectively. Plectropomus pessuliferus was the second favorite for both groups and Hipposcarus harid and Lethrinus lentjan were in 3rd and 4th place in terms of consumption. Average meal size was 68. g for Saudis and 128. g for expatriates. These data can be used by health professionals, risk assessors, and environmental regulators to examine potential risk from contaminants in fish, and to compare consumption rates with other sites. © 2014 Elsevier Inc.

    the 3D sub-volumes, which was bigger than one and smaller than two and had a decimal number. As a result, all remains could be imaged in the transparent 3D depth-volumes where the street could be revealed clearly. Finally three streets were revealed in the depth volumes. The first street was on the West part and the second street, which was parallel of the first street, was on the Southwest part of the Bouleuterion / Gerontikon and the third street was on the South of the library. Diggings on the West and Southwest parts of the research area encouraged the 3D image results. The second aim of the study was to find out native rocks of the Nysa remains and sources. The small rock samples were collected from the theatre, stadium, basement of agora and the tomb and analyzed under polarized microscope and confocal Raman spectroscopy. The results of the studies revealed that the main rocks of these remains composed of white color marble. These marbles have granoblastic texture composed of mainly pressure twinned calcite as coarse grain size under the polarized microscope. The confocal Raman spectroscopical studies revealed that the marble remains of Nysa ancient city were mainly built from Jurassic- Cretaceous carbonate rocks of Western Anatolia marble quarry in the vicinity region. This study was supported by the Scientific and Technological Research Council of Turkey (TUBITAK) under grant no. 107K523 and Earth Sciences Application and Research Center of Ankara University (YEBIM).

  9. Vitamin D deficiency among northern Native Peoples: a real or apparent problem?

    Directory of Open Access Journals (Sweden)

    Peter Frost

    2012-03-01

    Full Text Available Vitamin D deficiency seems to be common among northern Native peoples, notably Inuit and Amerindians. It has usually been attributed to: (1 higher latitudes that prevent vitamin D synthesis most of the year; (2 darker skin that blocks solar UVB; and (3 fewer dietary sources of vitamin D. Although vitamin D levels are clearly lower among northern Natives, it is less clear that these lower levels indicate a deficiency. The above factors predate European contact, yet pre-Columbian skeletons show few signs of rickets—the most visible sign of vitamin D deficiency. Furthermore, because northern Natives have long inhabited high latitudes, natural selection should have progressively reduced their vitamin D requirements. There is in fact evidence that the Inuit have compensated for decreased production of vitamin D through increased conversion to its most active form and through receptors that bind more effectively. Thus, when diagnosing vitamin D deficiency in these populations, we should not use norms that were originally developed for European-descended populations who produce this vitamin more easily and have adapted accordingly.

  11. Matis and Korubo, Contact, and Isolated Indigenous Peoples: Native Narratives and Ethnography in the Brazilian Amazon

    Directory of Open Access Journals (Sweden)

    Barbara Maisonnave Arisi

    2010-02-01

    Full Text Available This article is about isolation, contact, and relations between two Amazonian indigenous peoples: the Matis and the Korubo. Both groups, of the Panoan linguistic family, live in the Vale do Javari Indigenous Land, in the state of Amazonas, Brazil. The Matis were contacted by the Funai (the Brazilian agency for indigenous affairs in 1976, and they worked as intermediaries helping the Brazilian government to make contact with the Korubo in 1996. Since then, the Matis have been the main translators and mediators between the Korubo and the rest of the world (indigenous and non-indigenous. Based on my investigation, I propose to classify “isolation” in different ways and to relate the Matis’ own narratives about their contact with their neighbors the Korubo in order to approximate a native conception of what “isolation” and “isolated peoples” mean—if they mean anything at all.

    Full Text Available Objectives. To examine the epidemiology of infectious disease (ID hospitalisations among Alaska Native (AN people. Methods. Hospitalisations with a first-listed ID diagnosis for American Indians and ANs residing in Alaska during 2001–2009 were selected from the Indian Health Service direct and contract health service inpatient data. ID hospitalisations to describe the general US population were selected from the Nationwide Inpatient Sample. Annual and average annual (2007–2009 hospitalization rates were calculated. Results. During 2007–2009, IDs accounted for 20% of hospitalisations among AN people. The 2007–2009 average annual age-adjusted ID hospitalisation rate (2126/100,000 persons was higher than that for the general US population (1679/100,000; 95% CI 1639–1720. The ID hospitalisation rate for AN people increased from 2001 to 2009 (17%, p<0.001. Although the rate during 2001–2009 declined for AN infants (<1 year of age; p=0.03, they had the highest 2007–2009 average annual rate (15106/100,000, which was 3 times the rate for general US infants (5215/100,000; 95% CI 4783–5647. The annual rates for the age groups 1–4, 5–19, 40–49, 50–59 and 70–79 years increased (p<0.05. The highest 2007–2009 age-adjusted average annual ID hospitalisation rates were in the Yukon-Kuskokwim (YK (3492/100,000 and Kotzebue (3433/100,000 regions; infant rates were 30422/100,000 and 26698/100,000 in these regions, respectively. During 2007–2009, lower respiratory tract infections accounted for 39% of all ID hospitalisations and approximately 50% of ID hospitalisations in YK, Kotzebue and Norton Sound, and 74% of infant ID hospitalisations. Conclusions. The ID hospitalisation rate increased for AN people overall. The rate for AN people remained higher than that for the general US population, particularly in infants and in the YK and Kotzebue regions. Prevention measures to reduce ID morbidity among AN people should be increased in high

    Objective Information technology can improve the quality, safety, and efficiency of healthcare delivery by improving provider and patient access to health information. We conducted a nonrandomized, cross-sectional, self-report survey to determine whether Alaska Native and American Indian (AN/AI) people have access to the health communication technologies available through a patient-centered medical home. Methods In 2011, we administered a self-report survey in an urban, tribally owned and operated primary care center serving AN/AI adults. Patients in the center’s waiting rooms completed the survey on paper; center staff completed it electronically. Results Approximately 98% (n = 654) of respondents reported computer access, 97% (n = 650) email access, and 94% (n = 631) mobile phone use. Among mobile phone users, 60% had Internet access through their phones. Rates of computer access (p = .011) and email use (p = .005) were higher among women than men, but we found no significant gender difference in mobile phone access to the Internet or text messaging. Respondents in the oldest age category (65–80 years of age) were significantly less likely to anticipate using the Internet to schedule appointments, refill medications, or communicate with their health care providers (all p < .001). Conclusion Information on use of health communication technologies enables administrators to deploy these technologies more efficiently to address health concerns in AN/AI communities. Our results will drive future research on health communication for chronic disease screening and health management.

  14. The cosmological ideas of the peoples in the ancient Near East

    Science.gov (United States)

    Gropp, Harald

    The European astronomers Kepler and Brahe made a big step forwards to a new view of the world in the sixteenth century. Four or five thousands years earlier a lot of interesting cosmological ideas were developed in Mesopotamia, e.g. by Sumerians, Accadians, Babylonians or Assyrians. Many traditions in mathematics, astronomy, and astrology were started in these early cultures. The author discusses some of these ideas and, briefly, the cosmological ideas of those people who lived in many parts of Europe in the first millenium before Christ. These are the celts whose origin was in what is now called Bohemia, Germany and Austria, while after covered a wide area in Europe from British islands to Balcans. (Abstract and oral speech)

  17. The River of Life: Sustainable Practices of Native Americans and Indigenous Peoples

    Science.gov (United States)

    Marchand, Michael E.

    Examination of how Indigenous People have been forced to make adaptations from exploitation by Colonial powers for survival and explains how the resultant decision making models of Indigenous people, based on their traditions and culture, have promoted sustainable growth and development more in harmony with ecological systems. Grand Coulee Dam was built in 1942 in Washington state, destroying a major salmon fishery at Kettle Falls, thereby ending a 10,000 year lifestyle for the Colville Indians who lived on the river. This tribe and others on the Columbia River have subsequently been working to mitigate negative dam environmental impacts to restore fish and wildlife, so that they can maintain their cultural practices, and the entire region benefits from their efforts also. A key factor has been the oral traditions passed down from one generation to the next over thousands of years stressing the importance of protecting the environment for future generations Other examples are examined with other Indigenous people. The long range Indigenous goals and practices are compared versus more typical short range goals of modern economies in general.

    Full Text Available It is undeniable that the Internet has a capital importance in the contemporary society. In the new technological paradigm, known as the Information Age, the relevance of the network is equivalent to that of oil in the Industrial Age. Although we can dissent of the prediction done by Nicholas Negroponte in 1995, in its famous book “Being Digital”, with respect to which the digital divide would be translated in a subject, net, generational, expressed in the dichotomy: young person-rich versus old-poor men. However, this author (1995 guessed right in his theory of the greater facility of the young people towards the new technologies. For that reason, the Internet is dominated by young people. The appearance of Wena Naty, a video uploaded to the network (with the explicit consent of their protagonists in which a 14 year old girl practiced oral sex to a partner in a public square, is the most dramatic demonstration of the use and abuse that young Chileans make new technologies.The present article reviews data collected on the use of technologies in Chile (INJUV 2002, Godoy 2006 y PNUD 2006.

    Swamy, Ashwin Balegar

    This thesis involves development of an interactive GIS (Geographic Information System) based application, which gives information about the ancient history of Egypt. The astonishing architecture, the strange burial rituals and their civilization were some of the intriguing questions that motivated me towards developing this application. The application is a historical timeline starting from 3100 BC, leading up to 664 BC, focusing on the evolution of the Egyptian dynasties. The tool holds information regarding some of the famous monuments which were constructed during that era and also about the civilizations that co-existed. It also provides details about the religions followed by their kings. It also includes the languages spoken during those periods. The tool is developed using JAVA, a programing language and MOJO (Map Objects Java Objects) a product of ESRI (Environmental Science Research Institute) to create map objects, to provide geographic information. JAVA Swing is used for designing the user interface. HTML (Hyper Text Markup Language) pages are created to provide the user with more information related to the historic period. CSS (Cascade Style Sheets) and JAVA Scripts are used with HTML5 to achieve creative display of content. The tool is kept simple and easy for the user to interact with. The tool also includes pictures and videos for the user to get a feel of the historic period. The application is built to motivate people to know more about one of the prominent and ancient civilization of the Mediterranean world.

    An overview is provided of the positive impacts of the James Bay hydroelectric development on the native peoples of the northern Quebec region. The James Bay and Northern Quebec Agreement and its history is first reviewed, then some impacts of the LaGrande Complex development in the James Bay area are described. These include considerable progress in health care and social services, native management of the educational system, protection and encouragement of the traditional local economy, improvement of the local transportation system, increased native economic activity, and population growth. Environmental impacts are being reviewed on an ongoing basis, and environmental mitigation and enhancement programs are being carried out. Some environmental effects of the hydroelectric developments on waterfowl habitats, caribou herds, microclimate, and mercury levels in fish are noted. It is felt that these are minimal, or in the case of mercury levels, that they will diminish and stabilize over the long term. 1 tab.

    2014-08-01

    Full Text Available An event frequently goes beyond its own place and time in history and becomes a symbol of formation for national identity, even though there are always gaps, untold facts, or simply one of several versions of the history is told. Current paper clarifies some of the historical aspects that surrounded the establishing of Thanksgiving Day as an official holiday in the United States, and how this issue is dealt with in Native American Literature, especially in Sherman Alexie’s book The Absolutely true diary of a part time Indian. A postcolonial theoretical approach is used, emphasizing the concepts of transculturation, nation, resistance and subjectivity, based on the scholarly works by Bhabha (1998, Ashcroft et al. (2007 and Pratt (1992, coupled to Native American literary criticism by Vizenor (1998. Analyses show that, by using several strategies such as humor and criticism, Alexie questions not only the historical situation of the Native American in the United States, but also reveals the effects that those facts, which helped to produce US national thought, have on contemporary Native Americans.

Kathy was one of five people in 1999 to be awarded an IOP Public Awareness of Physics award. Dr Kathy Sykes What attracted you to Physics in the first place? It was really when I discovered that Physics was all about making models of the world, because then suddenly the ability to be creative became important. I liked the idea that you could have a picture of the world that might work quite well but you could always replace that with a better one. That was what made science come alive and make it seem like something that I'd really love to be involved in, rather than science as a stale body of facts that I needed to learn. I was much more interested in ideas than in facts. I think that finding out about 'models' happened around the time I was discovering quantum mechanics and how the act of observing something can actually affect the outcome. I found it incredibly exciting - especially how that changed the whole philosophy of science. I also had a fantastic teacher in physics and I owe an awful lot to him. He just swooped in at the last moment when I was considering giving it up so that made an enormous difference. After my degree I went to teach maths and physics A-level in Zimbabwe with the VSO, and it was partly wanting to share my excitement with other people about physics that made me want to go and teach abroad. When I came back and began my PhD in Physics at Bristol University, I missed teaching and thought it was important to get the public more involved in science and debates about science. My supervisor, Pete Barham, was doing lots of this himself, and he helped and encouraged me enormously. I can't thank him enough. Did you consider teaching as a career? Well I like having the carpet whipped away from

    Science.gov (United States)

    Mitchell-Fire Moon, Tandie Vera

    This study seeks to address the causes and potential solutions to the divisiveness and human destructiveness to humanity and the environment now reflected on a planetary scale. The research question is: How can Native American values enhance western thinking for the purpose of greater individual and planetary health? Fundamental research has been to develop the concept of `Integrity' as a model to explore various western concepts and Native knowledge as inter-facing systems. The model's formula integrates three major scientific theories-Relativity and Quantum Physics and Chaos, as a demonstration of the product of doing integrative thinking and research. Applying knowledge of Lakota Visionary Black Elk and other indigenous world views, this has evolved into a Unified Perceptual Field-``Toward a Theory of Wholeness.'' Study's goal is to utilize knowledge gained from this process to create greater positive choice in our fives, by designing systems that are highest functioning-creating greatest fulfillment, health and wholeness in the individual and the society. Methods of looking at data and wisdom in this study are the intuitive and analytical methodologies as defined in the Integrity Model. Part I, Visions and Stories from the DREAMTIME, reflects these knowledge quests. Within Part II, Native BASKETWEAVER Weaving New Realities, the thesis statement contains three major validations to emerge from this study: (1)The exploration inward reveals the deepest core of the material universe as the foundational, most subtle, powerful, infinitesimal quantum level of creation that we experience as our spiritual nature. (2)Trauma of physical impact by action, thought or word at early stages of human development disfigures the natural pattern of harmony, which is set into the biology/physiology-magnified and amplified in adult life, and mirrored out into space/time. (3)Early disturbance of one's perceptual intention (will/desire) weakens or breaks the natural underlying energy

    为探究中国古村落景观变迁的发生机理及不同行动者在此过程中的行为逻辑,对浙江省永嘉县境内的楠溪江古村落群进行了案例研究.从本土社会学的理论视角,指出:中国的乡土社会是一个情理社会,国家正式权力镶嵌于乡土文化之中,正式权力与非正式权力、政府与村民的互动推动了古村落景观的变迁.借用"国家-社会"二元框架,将变迁中的行动者分为县(市)政府,乡镇政府,有关系村民和无关系村民四类,指出不同的行动者具有各不相同又彼此联系的行为逻辑,为常态下的中国古村落景观变迁提供了一种行动者类型框架和一种理解方式.%To discover how ancient villages landscape changing and how to classify actors in the changing process, and to find out the logic behind actors' behaviors, this paper investigated Furong Village, an ancient village at Nanxi River Basin in Zhejiang Province, China. Qualitative research methods and native sociological theorries are adopted to analyze the phenomenon of landscape changing. By these, this paper concluded that, in China, the rural society is a Qingli society ( reasonableness society), and Tianli ( reason and morality), Renqing (favor), Mianzi (face) are very important. The formal power is embedded in rural culture, and the interaction between formal and informal power, between governments and villagers, caused the landscape changing. Borrowed the theoretical framework of ‘nation and society', actors in landscape changing are divided into four styles: the governors of counties, the governors of towns, the villagers who having Guanxi, and the villagers who have no Guanxi. Under the restriction of the protecting policy, villagers think themselves as ‘ martyr', as the people who cannot achieve enough residential space, thus they occupied the highland of Tianli. By the displacement of power, the villagers who having Guanxi can ‘borrow' power from the person who are

    ASE: Attend, Socialize, Enjoy Bob Kibble reflects on the enriching effects of the annual meeting Bob Kibble is a teacher trainer at the University of Edinburgh, Scotland. I remember my first ASE meeting in Reading. Perhaps in 1978 or thereabouts. I had been teaching for a few years and thought I'd check out this local convention of science teachers. It was indeed a revelation that so many people had so much to say about teaching science. There was talk about N and F levels and the 'I level grill'. Someone had ordered something called a BBC machine (later revealed to me as the latest in hi-tech teaching). I remember it well. But it was a lonely affair for a recent recruit. People seemed to know each other and there was much friendly exchanging. However, nobody knew me and I knew nobody else. The professional revelations were accompanied by a personal isolation. A strange set of memories indeed for a new recruit, unskilled and clumsy in the social arena. Bob practising for the ASE singalong session this year. This year I went to the ASE Centenary meeting in Guildford, my sixteenth ASE annual meeting. Things have changed since the early days. Thursday started with a formal Cathedral service in celebration of 100 years of the ASE. I sat next to a lady from Oxford and behind my good friend Dave from Croydon. Things snowballed from there.

For the public galleries of the NHM my group provides expert input to exhibitions-when the meteorite pavilion was recently refurbished we suggested a layout, wrote text and selected samples, but this was then 'edited' by the exhibition designers. I'm also working on a new website with virtual meteorite specimens. As an expert on Martian meteorites I often get interviewed by the media: for example, I am on a new Channel 4 programme called Destination Mars. I have also just finished a general interest book—it's called Search for Life; the NHM have just published it (in March). And do you get to go to exciting places? As a researcher I go to conferences I am just off to the States this week. I went to Antarctica ten years ago meteorite collecting and I am hoping to go to Australia this year. It is good fun but they really do need an expert who can recognise a meteorite. I'll be going to the Nullarbor region of Australia for 2 3 weeks depending on the weather if it's too green there is too much grass, so you can't see the meteorites. How do you find people respond to meteorites? People love touching rocks from outer space, especially primary school children. You can see how they are burnt on the outside. When you feel the weight of them it really brings it home: iron meteorites are heavy! They'll often say 'Wow, it fell from the sky' as they glance upwards, half expecting another one to come crashing through the ceiling. Everyone finds it amazing that a solid object has come as if from nowhere. And they are so old. They can't believe how old they are. We want to know where we come from. There is always lots of media coverage about what is happening in the sky (eclipses and the like). It's there and it's a bit of a mystery. If we can get to grips with how our planets and how our own Sun formed it can put us in the picture as to where we have come from and

    Very recently, we discovered a vast new microbial self: the human microbiome. Our native microbiota interface with our biology and culture to influence our health, behavior, and quality of life, and yet we know very little about their origin, evolution, or ecology. With the advent of industrialization, globalization, and modern sanitation, it is intuitive that we have changed our relationship with microbes, but we have little information about the ancestral state of our microbiome, and therefore, we lack a foundation for characterizing this change. High-throughput sequencing has opened up new opportunities in the field of paleomicrobiology, allowing us to investigate the evolution of the complex microbial ecologies that inhabit our bodies. By focusing on recent coprolite and dental calculus research, we explore how emerging research on ancient human microbiomes is changing the way we think about ancient disease and how archaeological studies can contribute to a medical understanding of health and nutrition today.

    The past decade has witnessed a revolution in ancient DNA (aDNA) research. Although the field's focus was previously limited to mitochondrial DNA and a few nuclear markers, whole genome sequences from the deep past can now be retrieved. This breakthrough is tightly connected to the massive sequence...... increasing the number of sequence reads to billions effectively means that contamination issues that have haunted aDNA research for decades, particularly in human studies, can now be efficiently and confidently quantified. At present, whole genomes have been sequenced from ancient anatomically modern humans......, archaic hominins, ancient pathogens and megafaunal species. Those have revealed important functional and phenotypic information, as well as unexpected adaptation, migration and admixture patterns. As such, the field of aDNA has entered the new era of genomics and has provided valuable information when...

    Full Text Available Objectives: Determine intake of fruits, vegetables and traditional foods (TF, availability of foods, and attitudes towards increasing their consumption. Study design: Establish community baseline through a cross-sectional sample of residents who were weighed, measured and interviewed. Village stores were surveyed for food availability, price and quality. Methods: Eighty-eight respondents self-identified as the household member primarily responsible for food shopping and cooking were surveyed in 3 Western Alaska Native villages using a food frequency questionnaire, and village stores were evaluated using food environment surveys. Results: Overweight (BMI[kg/m2] > 25 was present in 68% of participants. Fruit and vegetable intake (3.3 median servings/day was low in comparison to recommended intakes of 5–9 servings/d. Seventy-two per cent were eating less than 5 servings/d of fruits and vegetables combined. Thirty-four per cent of respondents were trying to eat more vegetables; 41% were trying to eat more fruits. The median number of servings of TF was 3.2/d (mean 4.3/d. Seventy-seven per cent of respondents reported that they ate enough TF. Conclusion: Recommendations to continue use of TF and increase intake of fruits and vegetables are consistent with local attitudes. Our findings indicate that increasing the availability of fruits and vegetables would be well received. Information from this study provides a basis for nutrition education and food supplement programs that is responsive to the needs and perceptions of the residents. Continued TF intake and increased fruit and vegetable intake have the potential to benefit the health of rural residents.

    The theme of suicide appears several times in ancient Greek literature. However, each such reference acquires special significance depending on the field from which it originates. Most of the information found in mythology, but the suicide in a mythological tale, although in terms of motivation and mental situation of heroes may be in imitation of similar incidents of real life, in fact is linked with the principles of the ancient Greek religion. In ancient drama and mainly in tragedies suicide conduces to the tragic hypostasis of the heroes and to the evolution of the plot and also is a tool in order to be presented the ideas of poets for the relations of the gods, the relation among gods and men and the relation among the men. In ancient Greek philosophy there were the deniers of suicide, who were more concerned about the impact of suicide on society and also these who accepted it, recognizing the right of the individual to put an end to his life, in order to avoid personal misfortunes. Real suicides will be found mostly from historical sources, but most of them concern leading figures of the ancient world. Closer to the problem of suicide in the everyday life of antiquity are ancient Greek medicines, who studied the phenomenon more general without references to specific incidents. Doctors did not approve in principal the suicide and dealt with it as insane behavior in the development of the mental diseases, of melancholia and mania. They considered that the discrepancy of humors in the organ of logic in the human body will cause malfunction, which will lead to the absurdity and consequently to suicide, either due to excessive concentration of black bile in melancholia or due to yellow bile in mania. They believed that greater risk to commit suicide had women, young people and the elderly. As therapy they used the drugs of their time with the intention to induce calm and repression in the ill person, therefore they mainly used mandragora. In general, we would say

    Housing is something that protects and defends. This book explores the ways in which humans have sought to defend themselves against physical dangers and to protect themselves against the imagined evils of the natural world by means of the shelters built. The book examines briefly the shelters built in ancient times, and shows how several basic types recurred in different ages and at different times. Following this there is a brief survey of the kinds of shelters built by the native peoples of Canada, depending on their environment--climate, the natural materials on hand--and the culture and life-style of each people. The next chapter explores the psychology of human beings, and how shelters should satisfy not only physical needs but psychological needs as well--the need for companionship and yet for privacy, space for children to play and community centers for adults to meet. The second half of the book looks at the dilemmas of housing today, and at various attempts around the world and in Canada to solve the problems--garden cities in England, the famous community of Tapiola in Finland, the technological innovations of Disneyland, new housing suburbs in Canada. There is a discussion of the problems of urban renewal, of overcoming the high cost of home-ownership--condominiums, cooperatives, owner-built homes, and the disadvantages of trailers--and of overcoming the energy crisis by building ecological houses.

    Ancient Chinese characters, typically the ideographic characters on bones and bronze before Shang Dynasty (16th—11th century B.C.), are valuable culture legacy of history. However the recognition of Ancient Chinese characters has been the task of paleography experts for long. With the help of modern computer technique, everyone can expect to be able to recognize the characters and understand the ancient inscriptions. This research is aimed to help people recognize and understand those ancient Chinese characters by combining Chinese paleography theory and computer information processing technology. Based on the analysis of ancient character features, a method for structural character recognition is proposed. The important characteristics of strokes and basic components or radicals used in recognition are introduced in detail. A system was implemented based on above method to show the effectiveness of the method.

    Like ancient people at other places of the world, the ancient Chinese lived in awe of the Sun. As they felt solar eclipses extremely significant events, they closely observed the occurrence of solar eclipse. Ancient astronomers further realized very early that solar eclipses were one of the important astronomical phenomena to revise and improve the ancient calendar. Interestingly, ancient emperors regarded solar eclipses as warnings from heaven that might affect the stability of their throne. Consequently, observing and recording solar eclipses became official, which dated far back to ancient China when numerous relevant descriptions were recorded in historical books. These records contribute substantially to China as an ancient civilization, as well as to the research of the long-term variation of the rotation rate of the Earth during >2000 years before the 17th century. This paper briefly reviews the perception, observations and recording of solar eclipses by ancient Chinese astronomers.

    Different aspects of medicine and/or healing in several societies are presented. In the ancient times as well as today medicine has been closely related to magic, science and religion. Various ancient societies and cultures had developed different views of medicine. It was believed that a human being has two bodies: a visible body that belongs to the earth and an invisible body of heaven. In the earliest prehistoric days, a different kind of medicine was practiced in countries such as Egypt, Greece, Rome, Mesopotamia, India, Tibet, China, and others. In those countries, "medicine people" practiced medicine from the magic to modern physical practices. Medicine was magical and mythological, and diseases were attributed mostly to the supernatural forces. The foundation of modern medicine can be traced back to ancient Greeks. Tibetan culture, for instance, even today, combines spiritual and practical medicine. Chinese medicine developed as a concept of yin and yang, acupuncture and acupressure, and it has even been used in the modern medicine. During medieval Europe, major universities and medical schools were established. In the ancient time, before hospitals had developed, patients were treated mostly in temples. PMID:18812066

    Most people are taught at a young age that Art and Science are two opposing subjects. My culture (Dakota-Sioux), teaches that every human being contains both male and female. The goal is to embrace the two opposing tendencies and live in balance. I am both a scientist (MS WashU 2008) and an artist (MFA Yale 2000). In my ambition to embrace both talents I have found very fertile ground. I will present a collection of "Four Direction Star Paintings". My ideas revolve around the four cardinal directions: North, East, South and West in relation to the four seasons and the stars as "teachers" or at least old friends. These ideas reflect everyday living as well as more intense Lakota ceremonies. The Star Paintings are sparkling, celestial guideposts. Amazingly, some of these ideas are embedded in both Western Science and Native American culture. This connection is golden. Indigenous peoples throughout the world have always had connections with the celestial skies. It is my goal to tap into this ancient connection and use it to establish new methodology for teaching science. Currently, I am painting a sixteen foot medicine teepee while working on my graduate degree in physics. I am funded by a Graduate Research Grant from the National Science Foundation.

    We are living in a definite time of change. Distinct changes are being experienced in our most sacred and natural environments. This is especially true on Native lands. Native people have lived for millennia in distinct and unique ways. The knowledge of balancing the needs of people with the needs of our natural environments is paramount in all tribal societies. This inherent accumulated knowledge has become the foundation on which to build a "blended" contemporary understanding of western science. The Dakota's and Northern California have embraced the critical need of understanding successful tribal strategies to engage educational systems (K-12 and higher education), to bring to prominence the professional development opportunities forged through working with tribal peoples and ensure the continued growth of Native earth and environmental scientists The presentation will highlight: 1) past and present philosophies on building and maintaining Native/Tribal students in earth and environmental sciences; 2) successful educational programs/activities in PreK-Ph.D. systems; 3) current Native leadership development in earth and environmental sciences; and 4) forward thinking for creating proaction collaborations addressing sustainable environmental, educational and social infrastructures for all people. Humboldt State University (HSU) and the University of North Dakota's Northern Great Plains Center for People and the Environment and the Upper Midwest Aerospace Consortium (UMAC) have been recognized nationally for their partnerships with Native communities. Unique collaborations are emerging "bridging" Native people across geographic areas in developing educational/research experiences which integrate the distinctive earth/environmental knowledge of tribal people. The presentation will highlight currently funded projects and initiatives as well as success stories of emerging Native earth system students and scientists.

    International Nuclear Information System (INIS)

    Syncrude Canada Ltd., operator of the oil sands mine and processing plant near Fort McMurray, Alberta, produces 11% of Canada's crude oil and is the country's largest private-sector employer of native Canadians. Syncrude has the goal of employing about 10% native Canadians, which is about the percentage of natives in the regional population. Examples are presented of successful native employment and entrepreneurship at Syncrude. Doreen Janvier, once employed at Syncrude's mine wash bays, was challenged to form her own company to contract out labor services. Her company, DJM Enterprises, now has a 2-year contract to operate three highly sophisticated wash bays used to clean mining equipment, and is looking to bid on other labor contracts. Mabel Laviolette serves as liaison between the oil containment and recovery team, who recover oil skimmed off Syncrude's tailings basin, and the area manager. The team approach and the seasonal nature of the employment fit in well with native cultural patterns. The excellence of native teamwork is also illustrated in the mine rescue team, one unit of which is entirely native Canadian. Part of Syncrude's aboriginal policy is to encourage development of aboriginal enterprises, such as native-owned Clearwater Welding and Fabricating Ltd., which has held welding and fabricating contracts with most major companies in the region and is a major supplier of skilled tradesmen to Syncrude. Syncrude also provides employment and training, encourages natives to continue their education, and promotes local community development. 4 figs

Here we describe a diet history questionnaire (DHQ) that was developed using an audio self-administered computer-assisted interview technique. The DHQ was developed for use in a cohort of American Indians and Alaskan Natives with tribal input and area-specific modules to incorporate local food availability. The DHQ includes 54 main food group questions, specific food items within the main food group, and food preparation and general eating practice questions. The questionnaire was programmed to be self-administered using a computer with a touch screen. The average time for the first 6,604 participants to complete the questionnaire was 36 minutes. Almost 100% of participants had complete DHQ data and the average number of food items selected was 70. The methods developed for collection of dietary data appear to be appropriate for the targeted population and may have usefulness for other populations where collecting dietary data in a self-administered format is desirable.

In a multi-site study, data were obtained from 294 individuals who consumed alcohol during the past year. The results indicated that 72.3% of men and 62.4% of women engaged in hazardous and harmful alcohol use and 50.8% of men and 48.7% of women met criteria for past-year alcohol dependence. The most common types of childhood maltreatment were physical abuse among male drinkers (62.7%) and emotional abuse (71.8%) among female drinkers. Men and women reported high percentages of out-of-home placement (39% and 47%, respectively). Logistic multiple regressions found that for male drinkers boarding school attendance and foster care placement were significant predictors of past-year alcohol dependence. For female drinkers, being adopted was significantly associated with a decreased risk of past-year drinking binge or spree. Dose-response relationships, using number of childhood exposures as a predictor, were not significant. The results highlight the need for alcohol and violence prevention and intervention strategies among urban two-spirit individuals. PMID:25317980

Because of extensive DNA...... degradation, these studies are limited to species that lived within the past 10(4)-10(5) years (Late Pleistocene), although DNA sequences from 10(6) years have been reported. Ancient DNA (aDNA) has been used to study phylogenetic relationships of protists, fungi, algae, plants, and higher eukaryotes such as...... early native Americans. Hence, ancient DNA contains information pertinent to numerous fields of study including evolution, population genetics, ecology, climatology, medicine, archeology, and behavior.

    2010-01-01

    The study of the ancient history of Indian medicine has recently been revived due to the publication of polyglot translations. However, little is known of ancient Indian pharmacy. Archaeological evidence suggests the Indus people lived a settled life approximately in 2500 B.C. Their cities were enjoying the cleanest and most hygienic daily life with elaborate civic sanitation systems. The whole conception shows a remarkable concern for health. Then, the early Aryans invaded India about 1500 B.C. and the Vedic age started. The Rgveda texts contain the hymns for Soma and those for herbs. The term Ayurveda (i.e., science of life) is found in some old versions of both Ramāyana and Mahābhārata and in the Atharvaveda. Suśruta had the credit of making a breakthrough in the field of surgery. The Ayurveda, a work on internal medicine, gives the following transmission of sages: Brahmā-->Daksa-->Prajāpati-->Aśivinau-->Indra-->Caraka. On the other hand, the Suśruta-samhitā, which deals mainly with surgical medicine, explains it as follows; Indra-->Dhanvantari-->Suśruta Both Caraka and Suśruta were medical doctors as well as pharmacists, so they studied more than 1000 herbs thoroughly. The Ayurveda had been used by his devotees for medical purposes. It eventually spread over Asia with the advanced evolution of Buddhism. PMID:21032887

    Full Text Available In spite of an array of effective antibiotics, tuberculosis is still very common in developing countries where overcrowding, malnutrition and poor hygienic conditions prevail. Over the past 30 years associated HIV infection has worsened the situation by increasing the infection rate and mortality of tuberculosis. Of those diseases caused by a single organism only HIV causes more deaths internationally than tuberculosis. The tubercle bacillus probably first infected man in Neolithic times, and then via infected cattle, but the causative Mycobacteriacea have been in existence for 300 million years. Droplet infection is the most common way of acquiring tuberculosis, although ingestion (e.g. of infected cows’ milk may occur. Tuberculosis probably originated in Africa. The earliest path gnomonic evidence of human tuberculosis in man was found in osteo-archaeological findings of bone tuberculosis (Pott’s disease of the spine in the skeleton of anEgyptian priest from the 21st Dynasty (approximately 1 000 BC. Suggestive but not conclusiveevidence of tuberculotic lesions had been found in even earlier skeletons from Egypt and Europe. Medical hieroglyphics from ancient Egypt are silent on the disease, which could be tuberculosis,as do early Indian and Chinese writings. The Old Testament refers to the disease schachapeth, translated as phthisis in the Greek Septuagint. Although the Bible is not specific about this condition, tuberculosis is still called schachapeth in modern Hebrew. In pre-Hippocratic Greece Homer did not mention phthisis, a word meaning non-specific wasting of the body. However. Alexander of Tralles (6th century BC seemed to narrow the concept down to a specific disease, and in the Hippocratic Corpus (5th-4th centuries BC phthisis can be recognised as tuberculosis. It was predominantly a respiratory disease commonly seen and considered to be caused by an imbalance of bodily humours. It was commonest in autumn, winter and spring

    Understanding the peopling history of Europe is crucial to comprehend the origins of modern populations. Of course, the analysis of current genetic data offers several explanations about human migration patterns which occurred on this continent, but it fails to explain precisely the impact of each demographic event. In this context, direct access to the DNA of ancient specimens allows the overcoming of recent demographic phenomena, which probably highly modified the constitution of the current European gene pool. In recent years, several DNA studies have been successfully conducted from ancient human remains thanks to the improvement of molecular techniques. They have brought new fundamental information on the peopling of Europe and allowed us to refine our understanding of European prehistory. In this review, we will detail all the ancient DNA studies performed to date on ancient European DNA from the Middle Paleolithic to the beginning of the protohistoric period. PMID:23052219

    Shanghai is the largest city in China, and it also has a very long history. Archaeologists have found that six thousand yeas ago, there were ancient people living at Songze, Qingpu County, Shanghai. This paper reports the study of ancient potteries unearthed from the Guangfulin site located at Songjiang, Shanghai. The potteries unearthed from Guangfulin site belonged to two different culture types: the Liangzhu culture type (local culture) and a new culture, which might be derived from elsewhere. PIXE has been used to measure the chemical compositions of samples and factor analysis was used. Experimental results show that the compositions of the pottery from the two phases are different from each other. It means that the raw materials used to make the ancient pottery originate from different places. This results support the idea suggested by archaeologists that a group of ancient people migrated to the Shanghai area from some other place 4000 years ago.

    2011-01-01

    The image of the classical Mediterranean environment of the Greeks and Romans had a formative influence on the art, literature, and historical perception of modern Europe and America. How closely does is this image congruent with the ancient environment as it in reality existed? In particular, how forested was the ancient Mediterranean world, was there deforestation, and if so, what were its effects? The consensus of historians, geographers, and other scholars from the mid-nineteenth century through the first three quarters of the twentieth century was that human activities had depleted the forests to a major extent and caused severe erosion. My research confirmed this general picture. Since then, revisionist historians have questioned these conclusions, maintaining instead that little environmental damage was done to forests and soils in ancient Greco-Roman times. In a reconsideration of the question, this paper looks at recent scientific work providing proxy evidence for the condition of forests at various times in ancient history. I look at three scientific methodologies, namely anthracology, palynology, and computer modeling. Each of these avenues of research offers support for the concept of forest change, both in abundance and species composition, and episodes of deforestation and erosion, and confirms my earlier work.

    In the Western tradition, words and vocabulary encapsulate much of how knowledge enters the public discourse, and is passed from one generation to the next. Much of Native American knowledge is passed along in an oral tradition. Chants and ceremonies contain context and long-baseline data on the environment (geology, climate, and astronomy) that may even surpasses the lifespan of a single individual. For Native American students and researchers, the concept of ‘modern research and science education’ may be wrapped up into the conundrum of assimilation and loss of cultural identification and traditional way of life. That conundrum is also associated with the lack of language and vocabulary with which to discuss 'modern research.' Native Americans emphasize the need to know themselves and their own culture when teaching their students. Many Native American communities recognize that the retention of their language - and need to make the language relevant to the technological age we live in, represents one of their largest and most urgent challenges. One strategy for making science education relevant to Native American learners is identifying appropriate terms that cross the cultural divide. More than just words and vocabulary, the thought processes and word/concept relationships can be quite different in the native cultures. The U.S. Rosetta Project has worked to identify words associated with Western 'STEM' concepts in three Native American communities: Navajo, Hawaiian, and Ojibwe. The U.S. Rosetta Project is NASA’s contribution to the International Rosetta Mission. The Rosetta stone, inspiration for the mission’s name, is expected to provide the keys to the primordial solar system the way the original Rosetta Stone provided a key to ancient language. Steps taken so far include identification and presentation of online astronomy, geology, and physical science vocabulary terms in the native language, identification of teachers and classrooms - often in

    The Indo-aryans of ancient India observed stars and constellations for ascertaining auspicious times for sacrificial rites ordained by vedas. It is but natural that they would have recounted in the vedic texts about comets. In Rigveda ($\\sim $ 1700 - 1500 BC) and Atharvaveda ($\\sim $ 1150 BC), there are references to dhumaketus and ketus, which stand for comets in Sanskrit. Varahamihira in 550 AD and Ballala Sena ($\\sim $ 1100 - 1200 AD) have described a large number of comets recorded by ancient seers such as Parashara, Vriddha Garga, Narada, Garga, etc. In this article, I conjecture that an episode narrated in Mahabharata of a radiant king, Nahusha, ruling the heavens, and later turning into a serpent after he had kicked the seer Agastya (also the star Canopus), is a mythological retelling of a cometary event.

    Owing to both their special appearance and behavior flatfish have attracted the special attention of people since ages. The first records of humans having been in touch with flatfish date back to the Stone Age about 15,000 years B.C. Detailed descriptions were already given in the classical antiquity and were taken up 1400 years later in the Renaissance by the first ichthyologists, encyclopédists, and also by practical men. This was more than 200 years before a number of common flatfish species were given their scientific names by Linnaeus in 1758. Besides morphology, remarkable and sometimes amusing naturalistic observations and figures are bequeathed. Ancient history of flatfish research is still a wide and open array. Examples are presented how the yield of information and interpretation from these times increases with interdisciplinary cooperation including archeologists, zoologists, ichthyologists, historians, art historians, fisheries and fishery biologist. The timeline of this contribution ends with the start of modern fishery research at the end of the 19th century in the course of the rapidly increasing exploitation of fish stocks.

    Exploring Ancient Skies brings together the methods of archaeology and the insights of modern astronomy to explore the science of astronomy as it was practiced in various cultures prior to the invention of the telescope. The book reviews an enormous and growing body of literature on the cultures of the ancient Mediterranean, the Far East, and the New World (particularly Mesoamerica), putting the ancient astronomical materials into their archaeological and cultural contexts. The authors begin with an overview of the field and proceed to essential aspects of naked-eye astronomy, followed by an examination of specific cultures. The book concludes by taking into account the purposes of ancient astronomy: astrology, navigation, calendar regulation, and (not least) the understanding of our place and role in the universe. Skies are recreated to display critical events as they would have appeared to ancient observers—events such as the supernova of 1054 A.D., the "lion horoscope," and the Star of Bethlehem. Explori...

    There is considerable evidence from iconographic and documentary sources that musical lip-reed instruments were important in the early celtic communities of Scotland and Ireland. In recent years several studies have been undertaken with the aim of gaining a better understanding of the musical nature of these ancient horns, and of their place in the life and culture of the time. A valuable source of tangible evidence is to be found in the archaeological remains deposited across Scotland and the whole of Ireland. A project is now under way, under the auspices of the Kilmartin House Trust and the general direction of John Purser, which has brought together an international team of musicians, craftsmen, archaeologists, musicologists and physicists with the aim of analyzing ancient musical artifacts, reconstructing some of the original instruments, and analyzing the sounds they produce. This paper describes acoustical studies carried out on a number of recent reconstructions of wooden and bronze instruments, and discusses the role of acoustics in this type of investigation.

    Ancient DNA recovered from 57 individuals excavated by Hiram Bingham at the rural communities of Paucarcancha, Patallacta, and Huata near the famed Inca royal estate and ritual site of Machu Picchu was analyzed by polymerase chain reaction, and the results were compared with ancient and modern DNA from various Central Andean areas to test their hypothesized indigenous highland origins. The control and coding regions of the mitochondrial DNA (mtDNA) of 35 individuals in this group were sequenced, and the haplogroups of each individual were determined. The frequency data for the haplogroups of these samples show clear proximity to those of modern Quechua and Aymara populations in the Peruvian and Bolivian highlands, and contrast with those of pre-Hispanic individuals of the north coast of Peru that we defined previously. Our study suggests a strong genetic affinity between sampled late pre-Hispanic individuals and modern Andean highlanders. A previous analysis of the Machu Picchu osteological collection suggests that the residents there were a mixed group of natives from various coastal and highland regions relocated by the Inca state for varied purposes. Overall, our study indicates that the sampled individuals from Paucarcancha and Patallacta were indigenous highlanders who provided supportive roles for nearby Machu Picchu. PMID:16485299

    Deng, Kehui

    Timekeeping was essential in the agricultural society of ancient China. The use of sundials for timekeeping was associated with the use of the gnomon, which had its origin in remote antiquity. This chapter studies three sundials (guiyi 晷仪) from the Qin and Han dynasties, the shorter shadow plane sundial (duanying ping yi 短影平仪) invented by Yuan Chong in the Sui Dynasty, and the sundial chart (guiyingtu 晷影图) invented by Zeng Minxing in the Southern Song dynasty. This chapter also introduces Guo Shoujing's hemispherical sundial (yang yi 仰仪). A circular stone sundial discovered at the Small Wild Goose Pagoda in Xi'an is also mentioned. It is dated from the Sui and Tang dynasties. A brief survey of sundials from the Qing dynasty shows various types of sundials.

    Tripitaka is the world's most comprehensive version of Buddhist sutra. There are limited numbers of Tripitaka currently preserved, most of them present various patterns of degradation. As little is known about the materials and crafts used in Tripitaka, it appeared necessary to identify them, and to further define adapted conservation treatment. In this work, a study concerning the paper source and dyestuff of the Tripitaka from approximate 16th century was carried out using fiber analysis and thin-layer chromatography (TLC). The results proved that the papers were mainly made from hemp or bark of mulberry tree, and indigo was used for colorizing the paper. At the end, we provide with suggestions for protecting and restoring the ancient Tripitaka.

    Full Text Available Ahiska or Meskhet Turks definations are geographical denominations, not etnic ones. Ahiska region and Turks living in this region was a natural part of Anatolian Turks as geopraphical and demographic. The precense of the Turks in this region known as Meskhetia in the history is based on ancient times. In the 11th century Seljuk conquests and then in the 12th century settlement of the Kipchak Turks, who came the region at the invitation of the Georgian king David who failed in fighting against Seljuks, enhanced the Turkish population at once. Thus, the Turks effectuated a full domination on the area in terms of the populatin. After a short time, in the middle 13th century Kipchaks declared their independence and founded their state named “Atabekler Devleti”. In history, this land dominated by The Kipchaks is known and displayed as Sa-Atabago (land of Atabegs by Georgians, too. The Atabegs Principality was captured by Ottoman State towards the end of 16th century and this principality was reorganized as Cildir Shire and Ahiska was done its capital city. In this region people have the same cultural codes with Anatolian Turks living on northeastern provinces of Turkey. Meskhetian Turks were exiled to Uzbekistan, Kazakhstan and Kyrgyzstan in 1944 when they lived in a province located in the southwest of Georgia and northeast of Turkey, and known as “Samtshe-Cavaheti” under the administrational umbrella of Georgia. Having not been allowed turning back to their hometowns, Meskhetian Turks live mostly in eight countries now and keep the characteristics of their dialect to a great extent which can be regarded as the following of Eastern Anatolian dialects. Ahıska ya da Mesket Türkleri tanımları etnik değil coğrafi bir adlandırma olup, Ahıska bölgesi ve Türkleri Anadolu Türklüğünün coğrafi ve demografik bakımdan tabii devamıdır.

    Hundreds of years ago, the ancient Chinese implemented several outstanding projects to cope with the changing climate and violent floods. Some of these projects are still in use today. These projects evolved from the experience and knowledge accumulated through the long coexistence of people with nature. The concepts behind these ancient stormwater management practices, such as low-impact development and sustainable drainage systems, are similar to the technology applied in modern stormwater management. This paper presents the cases of the Hani Terrace in Yunnan and the Fushou drainage system of Ganzhou in Jiangxi. The ancient Chinese knowledge behind these cases is seen in the design concepts and the features of these projects. These features help us to understand better their applications in the contemporary environment. In today's more complex environment, integrating traditional and advanced philosophy with modern technologies is extremely useful in building urban and rural stormwater management systems in China.

    With intensifying demands for food and biofuels, a critical threat to biodiversity is agricultural expansion into native tropical ecosystems. Tropical agriculture, particularly intensive agriculture, often supports few native organisms, and consequently has been largely overlooked in conservation planning; yet, recent work in the Neotropics demonstrates that tropical agriculture with certain features can support significant biodiversity, decades after conversion to farmland. It remains unknown whether this conservation value can be sustained for centuries to millennia. Here, we quantify the bird diversity affiliated with agricultural systems in southwest India, a region continuously cultivated for >2,000 years. We show that arecanut palm (Areca catechu) production systems retain 90% of the bird species associated with regional native forest. Two factors promote this high conservation value. First, the system involves intercropping with multiple, usually woody, understory species and, thus, has high vertical structural complexity that is positively correlated with bird species richness. Second, the system encompasses nearby forests, where large quantities of leaf litter are extracted for mulch. The preservation of these forests on productive land traces back to their value in supplying inputs to arecanut cultivation. The long-term biodiversity value of an agricultural ecosystem has not been documented in South and Southeast Asia. Our findings open a new conservation opportunity for this imperiled region that may well extend to other crops. Some of these working lands may be able to sustain native species over long-time scales, indicating that conservation investments in agriculture today could pay off for people and for nature.

  10. [Ancient Egyptian Odontology].

    Science.gov (United States)

    Berghult, B

    1999-01-01

    In ancient Egypt during the reign of Pharaoh Djoser, circa 2650 BC, the Step Pyramid was constructed by Imhotep. He was later worshiped as the God of Medicine. One of his contemporaries was the powerful writer Hesy who is reproduced on a panel showing a rebus of a swallow, a tusk and an arrow. He is therefore looked upon as being the first depicted odontologist. The art of writing begun in Egypt in about 3100 BC and the medical texts we know from different papyri were copied with hieratic signs around 1900-1100 BC. One of the most famous is the Papyrus Ebers. It was purchased by professor Ebers on a research travel to Luxor in 1873. Two years later a beautiful facsimile in color was published and the best translation came in 1958 in German. The text includes 870 remedies and some of them are related to teeth and oral troubles like pain in the mouth, gingivitis, periodontitis and cavities in the teeth. The most common oral pain was probably pulpitis caused by extreme attrition due to the high consumption of bread contaminated with soil and/or quern minerals. Another text is the Papyrus Edwin Smith with four surgical cases of dental interest. The "toothworms" that were presumed to bring about decayed teeth have not been identified in the medical texts. It was not until 1889 W.D. Miller presented a scientific explanation that cavities were caused by bacteria. In spite of extensive research only a few evidence of prosthetic and invasive treatments have been found and these dental artifacts have probably been made post mortem. Some of the 150 identified doctors were associated with treatments of disorders of the mouth. The stele of Seneb from Sa'is during the 26th dynasty of Psamtik, 664-525 BC, shows a young man who probably was a dental healer well known to Pharaoh and his court. Clement of Alexandria mentions circa 200 AD that the written knowledge of the old Egyptians was gathered in 42 collections of papyri. Number 37-42 contained the medical writings. The

  11. Pitfalls in the analysis of ancient human mtDNA

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The retrieval of DNA from ancient human specimens is not always successful owing to DNA deterioration and contamination although it is vital to provide new insights into the genetic structure of ancient people and to reconstruct the past history. Normally, only short DNA fragments can be retrieved from the ancient specimens. How to identify the authenticity of DNA obtained and to uncover the information it contained are difficult. We employed the ancient mtDNAs reported from Central Asia (including Xinjiang, China) as an example to discern potentially extraneous DNA contamination based on the updated mtDNA phylogeny derived from mtDNA control region, coding region, as well as complete sequence information. Our results demonstrated that many mtDNAs reported are more or less problematic. Starting from a reliable mtDNA phylogeney and combining the available modern data into analysis, one can ascertain the authenticity of the ancient DNA, distinguish the potential errors in a data set, and efficiently decipher the meager information it harbored. The reappraisal of the mtDNAs with the age of more than 2000 years from Central Asia gave support to the suggestion of extensively (pre)historical gene admixture in this region.

    2006-07-01

    Full Text Available Chaos theories developed in the last three decades have made very important contributions to our understanding of dynamical systems and natural phenomena. The meaning of chaos in the current theories and in the past is somewhat different from each other. In this work, the properties of dynamical systems and the evolution of chaotic systems were discussed in terms of the views of ancient philosophers. The meaning of chaos in Anaximenes’ philosophy and its role in the Ancient natural philosophy has been discussed in relation to other natural philosophers such as of Anaximander, Parmenides, Heraclitus, Empedocles, Leucippus (i.e. atomists and Aristotle. In addition, the fundamental concepts of statistical mechanics and the current chaos theories were discussed in relation to the views in Ancient natural philosophy. The roots of the scientific concepts such as randomness, autocatalysis, nonlinear growth, information, pattern, etc. in the Ancient natural philosophy were investigated.

    In this work, four ancient monuments of astronomical significance found in Athens and still kept in the same city in good condition are presented. The first one is the conical sundial on the southern slope of the Acropolis. The second one is the Tower of the Winds and its vertical sundials in the Roman Forum of Athens, a small octagonal marble tower with sundials on all 8 of its sides, plus a water-clock inside the tower. The third monument-instrument is the ancient clepsydra of Athens, one of the findings from the Ancient Agora of Athens, a unique water-clock dated from 400 B.C. Finally, the fourth one is the carved ancient Athenian calendar over the main entrance of the small Byzantine temple of the 8th Century, St. Eleftherios, located to the south of the temple of the Annunciation of Virgin Mary, the modern Cathedral of the city of Athens.

  17. Nuclear analytical methods on ancient Thai rice

    International Nuclear Information System (INIS)

    For more than half of humanity, rice is life. Rice is a grain which has shaped the history, culture, diet and economy of billions of people in Asia. In Thailand, it is the essence of life. Archaeological evidence revealed that rice had been planted in northeastern area of Thailand more than 5,500 years ago which is earlier than in China and India. The ancient rice grains were found in various archaeological sites in Thailand such as Nakhon Nayok, Suphan Buri and Prachin Buri Provinces. In this work, the ancient black rice from Nakhon Nayok Province was elementally analyzed using scanning electron microscope coupled with energy dispersive X-ray fluorescence spectroscopy, proton induced X-ray emission spectroscopy and micro-beam energy dispersive X-ray fluorescence spectroscopy. Infrared (IR) spectroscopy was also used to study the chemical composition and bio-molecular structure. The grains were oblique in shape with a rough surface. Three major elements (Si, Ca and Al) and other trace elements were detected. The IR spectra provided some information about the presence of molecular bonds. (author)

    Aveni, A F; Hartung, H; Buckingham, B

    1978-10-20

    Attention is directed to a design, possibly of Teotihuacan origin, carved both in rock and in the floors of ceremonial buildings throughout ancient Mesoamerica. Consisting generally of a double circular pattern centered on a set of orthogonal axes, the so-called pecked cross or quartered circle figure is shown to exhibit a remarkable consistency in appearance throughout its 29 reported locations, thus suggesting that it was not perfunctory. The metric properties of the symbols gleaned from field surveys are delineated, and several interpretations of their possible functions are discussed. These symbols may have been intended as astronomical orientational devices, surveyor's bench marks, calendars, or ritual games. Evidence is presented which implies that more than one and perhaps all of these functions were employed simultaneously, a view which is shown to be consistent with the cosmological attitude of the pre-Columbian people.

  5. Ancient DNA in Greece. Problems and prospects

    International Nuclear Information System (INIS)

    The promise associated with early 'ancient DNA' results has not been translated into routine techniques of value to archaeologists. The reasons for this are partly technical - ancient DNA analysis is an extremely difficult technique - and partly practical - ancient DNA analysis is often an 'after thought' to an archaeological project. In this paper ancient human DNA analysis is briefly reviewed paying particular attention to specimens originating from Greek archaeological contexts. Problems commonly encountered during ancient DNA research are summarised and recommendations for future strategies in the application of ancient DNA in archaeology are proposed. (author)

    Butler, Timothy; Waldroop, James

    2004-06-01

    Nearly all areas of business--not just sales and human resources--call for interpersonal savvy. Relational know-how comprises a greater variety of aptitudes than many executives think. Some people can "talk a dog off a meat truck," as the saying goes. Others are great at resolving interpersonal conflicts. Some have a knack for translating high-level concepts for the masses. And others thrive when they're managing a team. Since people do their best work when it most closely matches their interests, the authors contend, managers can increase productivity by taking into account employees' relational interests and skills when making personnel choices and project assignments. After analyzing psychological tests of more than 7,000 business professionals, the authors have identified four dimensions of relational work: influence, interpersonal facilitation, relational creativity, and team leadership. This article explains each one and offers practical advice to managers--how to build a well-balanced team, for instance, and how to gauge the relational skills of potential employees during interviews. To determine whether a job candidate excels in, say, relational creativity, ask her to describe her favorite advertising campaign, slogan, or image and tell you why she finds it to be so effective. Understanding these four dimensions will help you get optimal performance from your employees, appropriately reward their work, and assist them in setting career goals. It will also help you make better choices when it comes to your own career development. To get started, try the authors' free online assessment tool, which will measure both your orientation toward relational work in general and your interest level in each of its four dimensions.

  7. Aboriginal Determination: Native Title Claims and Barriers to Recognition

    Directory of Open Access Journals (Sweden)

    Zia Akhtar

    2011-09-01

    Full Text Available The Australian government has proposed a referendum in 2012 to decide the constitutional status of its indigenous people. There is at present no mechanism to define the indigenous people as a domestic or foreign entity of the Commonwealth. This is an important issue because other settler governments have developed a framework to implement their relationship with the native people. As a result, it is difficult prove title to land that has been abrogated by the deeds of the settlers. In Mabo v Queensland (2,the Commonwealth government was found to have breached its fiduciary duty to the Aboriginal peoples. The judgment led to the Native Title Act 1993 that established the process of asserting native rights that were held to coexist with pastoral ownership. The promulgation of the Native Title Amendment Act 1998 reversed this process and augmented the powers of non-native landlords by providing the device to extinguish native rights. In Western Australia v Ward, a mining lease was held to have precedence over native title that was adjudged to be part of a bundle of rights. In implementing the Native Title Act the issue turns on the determination of the ties to land/ sea that the government allows to the Aboriginal peoples. The judgment in Harrington-Smith on behalf of the Wongatha People v Western Australia indicates that title can be excluded on procedural grounds and that there was an incompatibility between the claims of the Aboriginal peoples and the settlers’ claims. The road map towards a more effective regime of proving title can be achieved if the Aboriginal peoples are granted recognition as a nation in the Constitution and a treaty is signed with them.

  15. Native Geosciences: Strengthening the Future Through Tribal Traditions

    Science.gov (United States)

    Bolman, J. R.; Quigley, I.; Douville, V.; Hollow Horn Bear, D.

    2008-12-01

    Native people have lived for millennia in distinct and unique ways in our natural sacred homelands and environments. Tribal cultures are the expression of deep understandings of geosciences shared through oral histories, language and ceremonies. Today, Native people as all people are living in a definite time of change. The developing awareness of "change" brings forth an immense opportunity to expand and elevate Native geosciences knowledge, specifically in the areas of earth, wind, fire and water. At the center of "change" is the need to balance the needs of the people with the needs of the environment. Native tradition and our inherent understanding of what is "sacred above is sacred below" is the foundation for an emerging multi-faceted approach to increasing the representation of Natives in geosciences. The approach is also a pathway to assist in Tribal language revitalization, connection of oral histories and ceremonies as well as building an intergenerational teaching/learning community. Humboldt State University, Sinte Gleska University and South Dakota School of Mines and Technology in partnership with Northern California (Hoopa, Yurok, & Karuk) and Great Plains (Lakota) Tribes have nurtured Native geosciences learning communities connected to Tribal Sacred Sites and natural resources. These sites include the Black Hills (Mato Paha, Mato Tiplia, Hinhan Kaga Paha, Mako Sica etc.), Klamath River (Ishkêesh), and Hoopa Valley (Natinixwe). Native geosciences learning is centered on the themes of earth, wind, fire and water and Native application of remote sensing technologies. Tribal Elders and Native geoscientists work collaboratively providing Native families in-field experiential intergenerational learning opportunities which invite participants to immerse themselves spiritually, intellectually, physically and emotionally in the experiences. Through this immersion and experience Native students and families strengthen the circle of our future Tribal

    The ancient Indians were the custodians of a highly evolved civilization with great awareness on the decisive importance as well as the vulnerability of man's natural environment. The ancient Indians sages and Rishis had considered human environment from the point of view of physical, chemical, biological and social process that influences directly or indirectly the health and well - being of the human kind. Their approach towards life was very comprehensive, highly integrated with the environment and, therefore, was ecologically sound and sustainable. It was aimed at promoting a peaceful coexistence with all the living organisms as well as a fuller harmony with the physical environment. The ancient masters tactfully implemented much of their value oriented teachings through certain rituals, taboos and totems and made the people to observe it as spiritual duty; the violation of which was feared an antispiritual. This approach had its astonishing impact and the people accepted these value oriented practices as a way of life and which in course of time became traditions for ages ensuring peaceful coexistence of human kind with other living organisms as well as with the physical environment. But with the advent of modern civilization most of these value oriented traditions are being either lost or discarded. The disappearance or disregard for such time tested environmental conservation or preservation oriented traditions had begun to show its detrimental effect on the life supporting system.

  1. Developments in Australia : native title and reconciliation

    Energy Technology Data Exchange (ETDEWEB)

    Chaney, F. [National Native Title Tribunal, Perth, WA (Australia)

    2004-07-01

    Until 1992, there was no recognition in the Australian legal system of property or other laws recognizing Indigenous rights concerning European colonial settlement and beyond. Native title was first recognized in 1992. This paper presented an outline of the history leading up to the creation of the National Native Title Tribunal in Perth, Australia, an organization whose aims are to create recognition of native title in Australia. The objects of the Native Title Act of 1993 were discussed, as well as attempts to reconcile indigenous and non-indigenous interests. Particular attention was drawn to the mining industry, as a practical example of the paradigm change in relation to indigenous rights, with an outline of the mining industry's values underlying principles concerning indigenous relations. It was concluded that while there are stringent limits on what is available through the native title process, mediation procedures mean that opportunities for agreement exist. Although reconciliation is in its infancy in Australia, there is a growing acceptance that Aboriginal rights must be considered. The agreement making which is encouraged by the native title process is an acknowledgment of a new relationship in which indigenous people are stakeholders. 72 refs., 5 figs.

    2011-12-01

    We are living in a definite time of change. Distinct changes are being experienced in our most sacred and natural environments. This is especially true on Native lands across the Americas. Native people have lived for millennia in distinct and unique ways. The knowledge of balancing the needs of people with the needs of our natural environments is paramount in all Tribal societies. These changes have accelerated the momentum to ensure the future of American Indian Geoscientists and Earth Systems Science Leaders. The presentation will bring to prominence the unique recruitment and mentoring necessary to achieve success that emerged through working with Tribal people. The presentation will highlight: 1) past and present philosophies on recruitment and mentoring of Native/Tribal students in geoscience and earth systems science; 2) current Native leadership and research development; 3) unique collaborations "bridging" Native people across geographic areas (International) in developing educational/research experiences which integrate the distinctive geoscience and earth systems science knowledge of Tribal peoples throughout the Americas. The presentation will highlight currently funded projects and initiatives as well as success stories of emerging Native geoscientists and earth systems science leaders.

  3. Native Americans and cultural impact analysis: The proposed nuclear waste repository at Hanford

    International Nuclear Information System (INIS)

    Beneath a surface patterning of legal, political, economic and other formal structures, Native American reservations and their tribes possess many culturally distinctive values and patterns of life. Generally it is this ancient underlying culture that Native American leaders wish to preserve and nourish. Their primary objective is tribal survival, and socioeconomic and cultural impact assessment theories and methods must reflect this objective. Conventional impact analysis rarely meets the needs of tribal leadership. Current, fragmented approaches must be replaced by integrative, holistic alternatives

  4. PIXE and INAA studies on ancient potteries from Guangfulin relics in Shanghai

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    This paper reports the study of ancient potteries unearthed from the Guangfulin site in Shanghai. From the external features of these potteries, archeologists can classify them into two different cultural types: Liangzhu culture (local culture) and a new culture which might be derived elsewhere, but they can not recognize whether they were produced in the same place. Proton induced X-ray emission (PIXE) and instrumental neutron activation analysis (INAA) were used to measure the chemical compositions of the samples and the results were analyzed using multivariate statistics. We found that the two methods can complement each other and their database can be mutually referenced in the study of ancient potteries. Experimental results show that the compositions of the potteries from the two cultural types are different, which means that the materials for ancient potteries of new culture originate from elsewhere. This supports the archaeologists' speculation that a group of ancient people migrated to Shanghai from some other places 4000 years ago.

    2005-05-01

    The strong relationships between Earth and sky in the worldviews of Native American people presents a wonderful opportunity for collaborations that can co-create compelling educational opportunities for both Native and non-Native learners. This paper will discuss the relationship among successful science education for Native Americans, standards-based science education, and informal science education. It will address some strategies for combining best practice in education with a deep cultural authenticity. Presenting astronomy in a culturally relevant and correct way is not only of value to the Native learner, but it is also of value to the non-Native learner because cultural relevance for Native people demands that science be presented via different learning modalities (e.g. visual, kinesthetic, tactile) and in a way that is more interconnected with other science and non-science disciplines. This kind of multi-modal and interdisciplinary approach is valuable and progressive for Non-native learners as well.

    随着旅游多样化发展,传统旅游资源已难以满足现代旅游者的需求,以彝人古镇为例,模仿式旅游资源随之应运而生。对旅游古镇的研究,虽然已有的研究内容及视角等都具有多样性,但从真实性视角对新出现的模仿式古镇进行的研究却知之甚少。彝人古镇是模仿式的,它没有原生文化系统却以彝族文化为依托,不是真实的传统古镇却给游客真实的旅游体验,所以,模仿式古镇的开发是值得倡导的,只是在开发时必须遵循文化的本质,避免文化因旅游而变迁或遗失。%With the development of tourism diversification, traditional tourism resources are difficult to meet the demand of modem tourists. Imitative tourism resources such as Yi Ancient Town have been built. Although the content and the perspective of the current study on ancient tourism town are very diverse, the study on new emerging imitative ancient town in the view of authenticity is little known. Yi Ancient Town is a style of imitation without native cultural system, but based on the culture of Yi people, which is not a traditional town in the true sense, but visitors who can enjoy a real experience for themselves in the town. Therefore, it is worth advocating the development of the imitative ancient town, but its development should follow the cultural nature and avoid the' changes or the losses of its culture.

    The development of next-generation sequencing has led to a breakthrough in the analysis of ancient genomes, and the subsequent genomic analyses of the skeletal remains of ancient humans have revolutionized the knowledge of the evolution of our species, including the discovery of a new hominin, and demonstrated admixtures with more distantly related archaic populations such as Neandertals and Denisovans. Moreover, it has also yielded novel insights into the evolution of ancient pathogens. The analysis of ancient microbial genomes allows the study of their recent evolution, presently over the last several millennia. These spectacular results have been attained despite the degradation of DNA after the death of the host, which results in very short DNA molecules that become increasingly damaged, only low quantities of which remain. The low quantity of ancient DNA molecules renders their analysis difficult and prone to contamination with modern DNA molecules, in particular via contamination from the reagents used in DNA purification and downstream analysis steps. Finally, the rare ancient molecules are diluted in environmental DNA originating from the soil microorganisms that colonize bones and teeth. Thus, ancient skeletal remains can share DNA profiles with environmental samples and identifying ancient microbial genomes among the more recent, presently poorly characterized, environmental microbiome is particularly challenging. Here, we describe the methods developed and/or in use in our laboratory to produce reliable and reproducible paleogenomic results from ancient skeletal remains that can be used to identify the presence of ancient microbiota.

    Since the dawn of medicine, medical rights and ethics have always been one of mankind's concerns. In any civilisation, attention paid to medical laws and ethics depends on the progress of human values and the advancement of medical science. The history of various civilisations teaches that each had its own views on medical ethics, but most had something in common. Ancient civilisations such as Greece, Rome, or Assyria did not consider the foetus to be alive and therefore to have human rights. In contrast, ancient Persians valued the foetus as a living person equal to others. Accordingly, they brought laws against abortion, even in cases of sexual abuse. Furthermore, abortion was considered to be a murder and punishments were meted out to the mother, father, and the person performing it. PMID:24304111

  4. Astronomy and its role in ancient Mesoamerica

    Science.gov (United States)

    Šprajc, Ivan

    2011-06-01

    The observation of the sky had an important rôle among the Maya, Aztecs and other prehispanic peoples of Mesoamerica. Their familiarity with the regularities of the apparent motion of the Sun, the Moon and bright planets is attested in a large amount of astronomical data contained in codices and monumental hieroglyphic inscriptions, as well as in their sophisticated calendrical system. On the other hand, the study of architectural alignments has disclosed that civic and ceremonial buildings were largely oriented on astronomical grounds, mostly to sunrises and sunsets on certain dates, allowing the use of observational calendars that facilitated a proper scheduling of agricultural and the associated ritual activities in the yearly cycle. Both accurate knowledge and other astronomically-derived concepts reveal that the significance attributed to certain celestial events by the ancient Mesoamericans can be explained in terms of the relationship of these phenomena with specific environmental and cultural facts, such as seasonal climatic changes and subsistence strategies. It was particularly due to its practical utility that astronomy, intertwined with religious ideas and practices, had such an important place in the worldview and, consequently, in the cosmologically substantiated political ideology of Mesoamerican societies

    This work is an outreach approach to an ubiquitous recent problem in secondary-school education: how to face back the decreasing interest in natural sciences shown by students under 'pressure' of convenient resources in digital devices/applications. The approach rests on two features. First, empowering of teen-age students to understand regular natural events around, as very few educated people they meet could do. Secondly, an understanding that rests on personal capability to test and verify experimental results from the oldest science, astronomy, with simple instruments as used from antiquity down to the Renaissance (a capability restricted to just solar and lunar motions). Because lengths in astronomy and daily life are so disparate, astronomy basically involved observing and registering values of angles (along with times), measurements being of two types, of angles on the ground and of angles in space, from the ground. First, the gnomon, a simple vertical stick introduced in Babylonia and Egypt, and then in Greece, is used to understand solar motion. The gnomon shadow turns around during any given day, varying in length and thus angle between solar ray and vertical as it turns, going through a minimum (noon time, at a meridian direction) while sweeping some angular range from sunrise to sunset. Further, the shadow minimum length varies through the year, with times when shortest and sun closest to vertical, at summer solstice, and times when longest, at winter solstice six months later. The extreme directions at sunset and sunrise correspond to the solstices, swept angular range greatest at summer, over 180 degrees, and the opposite at winter, with less daytime hours; in between, spring and fall equinoxes occur, marked by collinear shadow directions at sunrise and sunset.

  12. Dynamics of cultural transmission in Native Americans of the high Great Plains.

    Directory of Open Access Journals (Sweden)

    Stephen J Lycett

    Full Text Available Culture is a phenomenon shared by all humans. Attempts to understand how dynamic factors affect the origin and distribution of cultural elements are, therefore, of interest to all humanity. As case studies go, understanding the distribution of cultural elements in Native American communities during the historical period of the Great Plains would seem a most challenging one. Famously, there is a mixture of powerful internal and external factors, creating-for a relatively brief period in time-a seemingly distinctive set of shared elements from a linguistically diverse set of peoples. This is known across the world as the "Great Plains culture." Here, quantitative analyses show how different processes operated on two sets of cultural traits among nine High Plains groups. Moccasin decorations exhibit a pattern consistent with geographically-mediated between-group interaction. However, group variations in the religious ceremony of the Sun Dance also reveal evidence of purifying cultural selection associated with historical biases, dividing down ancient linguistic lines. The latter shows that while the conglomeration of "Plains culture" may have been a product of merging new ideas with old, combined with cultural interchange between groups, the details of what was accepted, rejected or elaborated in each case reflected preexisting ideological biases. Although culture may sometimes be a "melting pot," the analyses show that even in highly fluid situations, cultural mosaics may be indirectly shaped by historical factors that are not always obvious.

  13. Native fruit traits may mediate dispersal competition between native and non-native plants

    Directory of Open Access Journals (Sweden)

    Clare Aslan

    2012-02-01

    Full Text Available Seed disperser preferences may mediate the impact of invasive, non-native plant species on their new ecological communities. Significant seed disperser preference for invasives over native species could facilitate the spread of the invasives while impeding native plant dispersal. Such competition for dispersers could negatively impact the fitness of some native plants. Here, we review published literature to identify circumstances under which preference for non-native fruits occurs. The importance of fruit attraction is underscored by several studies demonstrating that invasive, fleshy-fruited plant species are particularly attractive to regional frugivores. A small set of studies directly compare frugivore preference for native vs. invasive species, and we find that different designs and goals within such studies frequently yield contrasting results. When similar native and non-native plant species have been compared, frugivores have tended to show preference for the non-natives. This preference appears to stem from enhanced feeding efficiency or accessibility associated with the non-native fruits. On the other hand, studies examining preference within existing suites of co-occurring species, with no attempt to maximize fruit similarity, show mixed results, with frugivores in most cases acting opportunistically or preferring native species. A simple, exploratory meta-analysis finds significant preference for native species when these studies are examined as a group. We illustrate the contrasting findings typical of these two approaches with results from two small-scale aviary experiments we conducted to determine preference by frugivorous bird species in northern California. In these case studies, native birds preferred the native fruit species as long as it was dissimilar from non-native fruits, while non-native European starlings preferred non-native fruit. However, native birds showed slight, non-significant preference for non-native fruit

  14. Romanian ancient gold objects studies using nuclear methods

    International Nuclear Information System (INIS)

    The study of trace-elements in archaeological metallic objects can provide important clues about the metal provenance and the involved manufacturing procedures, leading to important conclusions regarding the commercial, cultural and religious exchanges between the antique populations. Ancient metallic materials are usually inhomogeneous on a scale of 20 microns or less: they contain remains of imperfect smelting, segregated phases in alloys, inclusions. Due to their exceptional chemical stability, gold artifacts remain essentially unchanged during weathering and aging processes. Several fragments of ancient gold objects coming from an Eneolithic treasury and from Pietroasa 'Closca cu Puii de Aur' (The Golden Brood Hen with Its Chickens) hoard, unearthed on Romanian territory and two Romanian native gold nuggets samples were analysed using micro-PIXE technique. The purpose of the study was to clarify the metal provenance, establishing if the hypothesis of local gold holds. To reach this goal, trace elements (Cu, Te, Sn, Pb, Hg, As, Zr, Sb) and PGE (Platinum Group Elements) concentrations were determined. The presence of inclusions (micrometric size areas of composition different from the surroundings) was also checked. We found some Si, Ca, Fe ones on two Eneolithic samples, and Ta and Cr on a sample from Pietroasa hoard. The measurements led to conclusions regarding the alluvial origin of the gold for the Eneolithical samples and gave some indications for the possible gold ore sources of Pietroasa treasury, confirming the heterogeneity of this treasury (the two analysed pieces belonged to different stylistic and compositional groups).

    Although it has been said that the women in Ancient Egypt enjoyed a reasonable state of social and professional equality with men, this paper presents an alternate theory--that women were second-class citizens whose physical prowess was secondary to their role as sex objects. It appears that men and women in Ancient Egypt often participated in the…

  18. An ancient rangefinder for teaching surveying methods

    Rangefinders are instruments used for ballistics and for surveying in general. Here we propose a discussion of some of them, ranging from the ancient Rome to the modern methods. Using an ancient roman artefact as a model, we can pre-pare a rangefinder at no cost for teaching surveying methods to students of engineering and military schools

  19. Immigrants and Native Workers

    DEFF Research Database (Denmark)

    Foged, Mette; Peri, Giovanni

    Using a database that includes the universe of individuals and establishments in Denmark over the period 1991-2008 we analyze the effect of a large inflow of non-European (EU) immigrants on Danish workers. We first identify a sharp and sustained supply-driven increase in the inflow of non......-EU immigrants in Denmark, beginning in 1995 and driven by a sequence of international events such as the Bosnian, Somalian and Iraqi crises. We then look at the response of occupational complexity, job upgrading and downgrading, wage and employment of natives in the short and long run. We find that the...... increased supply of non-EU low skilled immigrants pushed native workers to pursue more complex occupations. This reallocation happened mainly through movement across firms. Immigration increased mobility of natives across firms and across municipalities but it did not increase their probability of...

  20. Count like an egyptian a hands-on introduction to ancient mathematics

    CERN Document Server

    Reimer, David

    2014-01-01

    The mathematics of ancient Egypt was fundamentally different from our math today. Contrary to what people might think, it wasn't a primitive forerunner of modern mathematics. In fact, it can't be understood using our current computational methods. Count Like an Egyptian provides a fun, hands-on introduction to the intuitive and often-surprising art of ancient Egyptian math. David Reimer guides you step-by-step through addition, subtraction, multiplication, and more. He even shows you how fractions and decimals may have been calculated-they technically didn't exist in the land of the pharaohs.

  1. Mechanisms in ancient Chinese books with illustrations

    CERN Document Server

    Hsiao, Kuo-Hung

    2014-01-01

    This book presents a unique approach for studying mechanisms and machines with drawings that were depicted unclearly in ancient Chinese books. The historical, cultural and technical backgrounds of the mechanisms are explained, and various mechanisms described and illustrated in ancient books are introduced. By utilizing the idea for the conceptual design of modern mechanisms, all feasible designs of ancient mechanisms with uncertain members and joints that meet the technical standards of the subjects’ time periods are synthesized systematically. Ancient Chinese crossbows (the original crossbow and repeating crossbows), textile mechanisms (silk-reeling mechanism, spinning mechanisms, and looms), and many other artisan's tool mechanisms are used as illustrated examples.  Such an approach provides a logical method for the reconstruction designs of ancient mechanisms with uncertain structures. It also provides an innovative direction for researchers to further identify the original structures of mechanisms...

  2. Native fruit traits may mediate dispersal competition between native and non-native plants

    OpenAIRE

    2012-01-01

    Seed disperser preferences may mediate the impact of invasive, non-native plant species on their new ecological communities. Significant seed disperser preference for invasives over native species could facilitate the spread of the invasives while impeding native plant dispersal. Such competition for dispersers could negatively impact the fitness of some native plants. Here, we review published literature to identify circumstances under which preference for non-native fruits occurs. The impor...

    DNA obtained from environmental samples such as sediments, ice or water (environmental DNA, eDNA), represents an important source of information on past and present biodiversity. It has revealed an ancient forest in Greenland, extended by several thousand years the survival dates for mainland...... woolly mammoth in Alaska, and pushed back the dates for spruce survival in Scandinavian ice-free refugia during the last glaciation. More recently, eDNA was used to uncover the past 50 000 years of vegetation history in the Arctic, revealing massive vegetation turnover at the Pleistocene....../Holocene transition, with implications for the extinction of megafauna.

  4. Archimedes: Accelerator Reveals Ancient Text

    International Nuclear Information System (INIS)

    Archimedes (287-212 BC), who is famous for shouting 'Eureka' (I found it) is considered one of the most brilliant thinkers of all times. The 10th-century parchment document known as the 'Archimedes Palimpsest' is the unique source for two of the great Greek's treatises. Some of the writings, hidden under gold forgeries, have recently been revealed at the Stanford Synchrotron Radiation Laboratory at SLAC. An intense x-ray beam produced in a particle accelerator causes the iron in original ink, which has been partly erased and covered, to send out a fluorescence glow. A detector records the signal and a digital image showing the ancient writings is produced. Please join us in this fascinating journey of a 1,000-year-old parchment from its origin in the Mediterranean city of Constantinople to a particle accelerator in Menlo Park.

    2003-01-01

    This paper reviews twenty-eight Chinese medicine books with complete prescriptions prior to the Qing Dynasty, and analyzes the characteristics of acupoint selection and needling manipulations from the perspective of apoplectic symptoms. It is concluded that,in ancient times, apoplexy is often treated on the basis of its symptoms and a great number of acupoints are employed; hemiplegia is mainly treated by the acupoints of the Large Intestine Meridian and Gallbladder Meridian,with two key acupoints; coma is mainly treated by first-aid acupoints and qi-supplementing acupoints, with seven key acupoints; wry mouth and convulsion are mainly treated by the local acupoints; as for needling manipulations, moxibustion with moxa cones is principally used, while needling is less used.

    Maria Rosso, Ana

    2010-01-01

    In Ancient Egypt, light and fire, which were closely related to the Sun God Ra, were the sources of life and well-being, while the dark meant danger and death. Similar to death, darkness drops on human beings in deep sleep and they enter a space inhabited by shadows. Dreams were believed to reveal an unknown world, to give the sleeper a glimpse into the future. Vision attracts distant objects and their light, on the other hand, can hurt the eyes like a burning flame. Eyes were the most important organ in Egyptian thought, as they allowed perception of the real world. Their importance has been immortalised in the myth of the Eye of Horus that explains the role of either eye. One represents the moonlight, which disperses the darkness of the night, and the other represents the sunshine, which creates life, and both could also represents the power of human intellect. Blindness, in turn, congenital or disease-related, was considered a divine punishment. A man, thus handicapped, would sink in a state of uncertainty and darkness. To protect the eyes from blindness, people used drops and ointments, which were believed to chase away all kinds of insects and demons that threatened with a variety of eye infections. Egyptian eye doctors or physicians, carried a special kit that contained green chrysocolla and a black kohl makeup, highly appreciated as prophylaxis because they personified Osiris' humours or body fluids. These products were offered to Gods to restore the brightness of divine glance and incite sun and moon to spread their beneficial light. PMID:21192112

    Jock M. Agai

    2013-07-01

    Full Text Available There are many cultural practices that connect ancient Egyptians to the Yorubas and the new interpretation of the Oduduwa legend suggests that the Yorubas have originated or are influenced mainly by the Egyptians. The attestation of Egypt as the main influencer of the Yoruba culture made Egypt significant in the study of the history of the Yoruba people. Some writers are beginning to think that the ancient Egyptians were responsible for introducing and spreading many cultures amongst the Yorubas. As more Yorubas are tracing their origins and the origins of their culture to ancient Egypt, this research investigates whether the Egyptians were the originators and the main spreaders of the afterlife culture in Yorubaland.

    Directory of Open Access Journals (Sweden)

    Nikolay Alekseevich VOLKOV

    2015-12-01

    Full Text Available Emergence of the idea of human rights in V— VI centuries BC in ancient policies and emergence of the principle of citizenship became a major step on the way of humanity towards freedom and progress. The idea and practice of freedom and human rights was given to the world by the most famous of all ancient civilizations — Athens in the views of Heraclitus, Democritus, Protagoras, Antiphont, Socrates, Plato, Aristotle, Epicurus, etc. Ancient Greek ideas about human rights formed as a part of mythological views that the polis or the citystate and its laws are of divine origin and are based on divine justice. Further development of sociophilosophical and political-legal concepts of human rights in Ancient Greece occurred in search and substantiation, along with the divine origin, of objective natural-legal basis for the existence of the polis, its laws and social existence of people. Natural-legal ideas of ancient Greek thinkers about freedom and equality of all human beings further developed in Ancient Rome, and especially in the philosophical and legal views of the Stoics Seneca, Marcus Aurelius, and Cicero, the ancient Roman thinker, philosopher and orator. In their teaching on human rights, the natural-legal idea of freedom and equality was extended beyond the narrow polis and ethnic framework and was expanded to all members of the humankind as fellow citizens of a single cosmopolitan state. According to the results of the conducted research, the author notes that the ancient thinkers, prominent representatives of philosophical, legal, and political thought of that time laid the foundations of the doctrine of human rights, which was further developed in the medieval beliefs of medieval representatives, especially in the views of the authors of the liberal world outlook of the New times. The English and American Age of Enlightenment, French bourgeoisdemocratic revolution have become a new important milestone and a new stage in theoretical

First one, that Greek word sema means a sign but a tombstone, too. It is related to problem of a human memory (a Greek anamnesis. Second one that death is primarily darkening for ancient people. Thanatos – god of death – appears only as a fragment of goddess Night, his mother. Third one, that a fire (or light is import for life of human being. But a fire has symbolical function and it is related to an eternity. There is a light nearby intelligence in ancient world. Desire of philosophers to immortality refers to desire to an eternal intellectual thinking.

    Full Text Available Sleep behavior patterns in childhood are influenced by familial, cultural and environmental factors. In understanding sleep in Native Brazilian Bororo children, one should consider the influence of their culture on the child's sleep. This research analyzes sleep habits of Native Bororo children from the Meruri village, located in an Indian Reservation in the state of Mato Grosso. Fourty four children ( 24 M; 20 F were evaluated; ages ranged from one month to 10 years, with a mean age of 4.9 years. Sleep characteristics were assessed by means of a standard questionnaire applied to the mothers. Cosleeping - sleeping together with family members - was a remarkable finding, in every child 0-2 year old and in 81.5% in the 2-10 years group. The second characteristic was sleeping with many people in the same room. There was an average of 5.1 people per room in the younger group and 3.9 people in the older group

    2013-01-01

    The idea of implementing ancient water and wastewater technologies in the developing world is a persuasive one, since ancient systems had many features which would constitute sustainable and decentralised water and sanitation (WATSAN) provision in contemporary terminology. Latest figures indicate 2.6 billion people do not use improved sanitation and 1.1 billion practise open defecation, thus there is a huge need for sustainable and cost-effective WATSAN facilities, particularly in cities of the developing world. The objective of this study was to discuss and evaluate the applicability of selected ancient WATSAN systems for the contemporary developing world. Selected WATSAN systems in ancient Mesopotamia, the Indus Valley, Egypt, Greece, Rome and the Yucatan peninsula are briefly introduced and then discussed in the context of the developing world. One relevant aspect is that public latrines and baths were not only a part of daily life in ancient Rome but also a focal point for socialising. As such they would appear to represent a model of how to promote use and acceptance of modern community toilets and ablution blocks. Although public or community toilets are not classified as improved sanitation by WHO/UNICEF, this is a debatable premise since examples such as Durban, South Africa, illustrate how community toilets continue to represent a WATSAN solution for urban areas with high population density. Meanwhile, given the need for dry sanitation technologies, toilets based on the production of enriched Terra Preta soil have potential applications in urban and rural agriculture and warrant further investigation.

    2010-12-01

    Native people have lived for millennia in distinct and unique ways in our natural sacred homelands and environments. Tribal cultures are the expression of deep understandings of geosciences shared through oral histories, language, traditional practices and ceremonies. Today, Native people as all people are living in a definite time of change. The developing awareness of "change" brings forth an immense opportunity to expand, elevate and incorporate Traditional Native geosciences knowledge into modern research and education to expand understandings for all learners. At the center of "change" is the need to balance the needs of the people with the needs of the environment. Native traditions and our inherent understanding of what is "sacred above is sacred below" is the foundation for a multi-faceted approach for increasing the representation of Natives in geosciences. The approach is centered on the incorporation of traditional knowledge into modern research/education. The approach is also a pathway to assist in Tribal language revitalization, connection of oral histories and ceremonies to place and building an intergenerational teaching/learning community. Humboldt State University, Sinte Gleska University and Tribes in Northern California (Hoopa, Yurok, & Karuk) and Great Plains (Lakota) Tribes have nurtured Native geosciences learning and research communities connected to Tribal Sacred Sites and natural resources. Native geoscience learning is centered on the themes of earth, wind, fire and water and the Native application of remote sensing technologies. Tribal Elders and Native geoscientists work collaboratively providing Native families in-field experiential intergenerational learning opportunities which invite participants to immerse themselves spiritually, intellectually, physically and emotionally in the experiences. Through this immersion and experience Native students and families strengthen the circle of our future Tribal communities and a return to

  13. Rethinking the Ancient Sulfur Cycle

    Science.gov (United States)

    Fike, David A.; Bradley, Alexander S.; Rose, Catherine V.

    2015-05-01

    The sulfur biogeochemical cycle integrates the metabolic activity of multiple microbial pathways (e.g., sulfate reduction, disproportionation, and sulfide oxidation) along with abiotic reactions and geological processes that cycle sulfur through various reservoirs. The sulfur cycle impacts the global carbon cycle and climate primarily through the remineralization of organic carbon. Over geological timescales, cycling of sulfur is closely tied to the redox state of Earth's exosphere through the burial of oxidized (sulfate) and reduced (sulfide) sulfur species in marine sediments. Biological sulfur cycling is associated with isotopic fractionations that can be used to trace the fluxes through various metabolic pathways. The resulting isotopic data provide insights into sulfur cycling in both modern and ancient environments via isotopic signatures in sedimentary sulfate and sulfide phases. Here, we review the deep-time δ34S record of marine sulfates and sulfides in light of recent advances in understanding how isotopic signatures are generated by microbial activity, how these signatures are encoded in marine sediments, and how they may be altered following deposition. The resulting picture shows a sulfur cycle intimately coupled to ambient carbon cycling, where sulfur isotopic records preserved in sedimentary rocks are critically dependent on sedimentological and geochemical conditions (e.g., iron availability) during deposition.

    Population mixture is an important process in biology. We present a suite of methods for learning about population mixtures, implemented in a software package called ADMIXTOOLS, that support formal tests for whether mixture occurred and make it possible to infer proportions and dates of mixture. We also describe the development of a new single nucleotide polymorphism (SNP) array consisting of 629,433 sites with clearly documented ascertainment that was specifically designed for population genetic analyses and that we genotyped in 934 individuals from 53 diverse populations. To illustrate the methods, we give a number of examples that provide new insights about the history of human admixture. The most striking finding is a clear signal of admixture into northern Europe, with one ancestral population related to present-day Basques and Sardinians and the other related to present-day populations of northeast Asia and the Americas. This likely reflects a history of admixture between Neolithic migrants and the indigenous Mesolithic population of Europe, consistent with recent analyses of ancient bones from Sweden and the sequencing of the genome of the Tyrolean “Iceman.” PMID:22960212

  5. Radiocarbon dating of ancient Japanese documents

    International Nuclear Information System (INIS)

    History is a reconstruction of past human activity, evidence of which is remained in the form of documents or relics. For the reconstruction of historic period, the radiocarbon dating of ancient documents provides important information. Although radiocarbon age is converted into calendar age with the calibration curve, the calibrated radiocarbon age is still different from the historical age when the document was written. The difference is known as 'old wood effect' for wooden cultural property. The discrepancy becomes more serious problem for recent sample which requires more accurate age determination. Using Tandetron accelerator mass spectrometer at Nagoya University, we have measured radiocarbon ages of Japanese ancient documents, sutras and printed books written dates of which are clarified from the paleographic standpoint. The purpose is to clarify the relation between calibrated radiocarbon age and historical age of ancient Japanese document by AMS radiocarbon dating. This paper reports 23 radiocarbon ages of ancient Japanese documents, sutras and printed books. The calibrated radiocarbon ages are in good agreement with the corresponding historical ages. It was shown by radiocarbon dating of the ancient documents that Japanese paper has little gap by 'old wood effect'; accordingly, ancient Japanese paper is a suitable sample for radiocarbon dating of recent historic period.

    2015-01-01

    Full Text Available This work examines the historic and current policies regarding Native American archives, detailing the broader historic landscape of information services for tribal communities, the initiative to develop tribal archives in Indian Country, and the activism surrounding the proper care and management of Native American archive collections at non-Native repositories. Utilizing Vine Deloria's "Right to Know" call to action, the paper analyzes major activities and achievements of the national indigenous archives movement with a specific focus on archival activists and tribal communities in the American West who were at the forefront of a grassroots movement to establish and develop tribal archives, return and secure tribal history and rights during the restoration era, and establish training and best practices for the respectful care of indigenous collections. Possible next steps are suggested for decolonizing Native American archives within the context of the United Nations Declaration on the Rights of Indigenous Peoples.

    Relatively little is known about differences in English-administered, clinical neuropsychological test performance between native versus non-native English speakers, with prior literature yielding mixed findings. The purpose of this study was to examine the performance of native and non-native English speakers with similar age and educational backgrounds on a variety of cognitive tests. Participants were 153 university students (115 native and 38 non-native English speakers) who completed a neuropsychological battery during two testing sessions. Multiple regression analyses examined relations of native language to cognitive performance after adjustment for age, education, sex, and depressive symptomatology. Results showed that native English speakers outperformed non-native English speakers on several language-mediated tasks-Letter and Category Fluency and the Cognitive Estimation Test-as well as Trails A (p's executive functions, perceptuo-motor speed, verbal memory, and visuospatial abilities. These results suggest that non-native English language may have a negative influence predominantly on language-dependent tasks. PMID:22985952

    The historical experience in China of constructing healthy buildings over many centuries merits even more attention today. Using the quadrangle as a basic style, buildings have been constructed in this way from ancient China to the present time. It is a style found in all areas of the country. The buildings in which people lived in ancient China were designed according to the doctrine of wind and water (which in Chinese is called feng shui). Today we would describe this as a philosophy for designing the indoor environment for healthy living. The common properties of such buildings are that of having good indoor air quality and easy maintenance of the indoor climate. This paper describes the optimal performance of quadrangle buildings from the perspective of their environment, illumination by natural lighting, infrared absorption and radiation, noise and indoor air quality, insulation properties and gives a mathematical analysis of these features. While this building style is not unique to China it could be developed more in other countries. It is a healthy style of building which can serve mankind worldwide because of its natural energy saving and adopting more widely it would improve standards in building.

    Initially, infants are capable of discriminating phonetic contrasts across the world's languages. Starting between seven and ten months of age, they gradually lose this ability through a process of perceptual narrowing. Although traditionally investigated with isolated speech sounds, such narrowing occurs in a variety of perceptual domains (e.g., faces, visual speech). Thus far, tracking the developmental trajectory of this tuning process has been focused primarily on auditory speech alone, and generally using isolated sounds. But infants learn from speech produced by people talking to them, meaning they learn from a complex audiovisual signal. Here, we use near-infrared spectroscopy to measure blood concentration changes in the bilateral temporal cortices of infants in three different age groups: 3-to-6 months, 7-to-10 months, and 11-to-14-months. Critically, all three groups of infants were tested with continuous audiovisual speech in both their native and another, unfamiliar language. We found that at each age range, infants showed different patterns of cortical activity in response to the native and non-native stimuli. Infants in the youngest group showed bilateral cortical activity that was greater overall in response to non-native relative to native speech; the oldest group showed left lateralized activity in response to native relative to non-native speech. These results highlight perceptual tuning as a dynamic process that happens across modalities and at different levels of stimulus complexity. PMID:25116572

    2007-11-01

    Full Text Available Human skeletal and dental remains are an invaluable source of information for interpreting the way of life of past people and also provide the only direct evidence of non-living populations’ health status. This research paper discusses the sex-related health differences observed in two skeletal populations from Greece, an ancient and a modern, by employing multiple health indicators, and aims at determining the biological and possible social factors that contribute to this variation. Particular emphasis is given to the importance of hypotheses-driven, population-based studies of human remains as the most effective means of reconstructing life in the past. The results showed that fracture ('ancient': females 0.08%, males 0.12%; 'modern': females 0.38%, males 0.19% and osteoarthritis ('ancient': females 0.7%, males: 3.0%; 'modern': females 4.4%, males 3.2% frequencies were higher for male individuals than females in the ancient population, which can be explained by greater engagement in strenuous and risky activity. Dental caries ('ancient': females 1.2%, males 1.8%; 'modern': females 23.6%, males 17.4% and ante-mortem tooth loss ('ancient': females 12.3%, males 7.7%; 'modern': females 69.5%, males 49.5% rates were higher for females than males (with the exception of the almost equal caries rates for the ancient population, most likely due to hormonal fluctuations, saliva content and flow, because female teeth erupt earlier and also perhaps as a result of differences in dietary habits. Periodontitis levels were more elevated in males ('ancient': females 9.6%, males 30.1%; 'modern': females 29.1%, males 38.3%, possibly due to poor oral hygiene practices and excessive masticatory loading. Dental enamel defects rates showed that in the ancient population, males had more chances of surviving childhood stress than females (females 19.5%, males 20.0%, whereas, in the modern population, the exact opposite was the case (females 6.1%, males 22.7%.

    Lice are among the oldest parasites of humans representing an excellent marker of the evolution and migration of our species over time. Here, we analyzed by real-time polymerase chain reaction (RT-PCR) developed in this study the mitochondrial DNA of seven ancient head louse eggs found on hair remains recovered from two sites in Israel: 1) five nits dating from Chalcolithic period (4,000 bc) were found in the Cave of the Treasure located at Nahal Mishmar, in the Judean Desert and 2) two nits dating from Early Islamic Period (ad 650-810) were found in Nahal Omer in the Arava Valley (between Dead Sea and Red Sea). Our results suggest that these eggs belonged to people originating from west Africa based on identification of the louse mitochondrial sub-clade specific to that region. PMID:26078317

    The excavation of a frozen grave on the Kizil site (dated to be 2500 years old) in the Altai Republic (Central Asia) revealed a skeleton belonging to the Scytho-Siberian population. DNA was extracted from a bone sample and analyzed by autosomal STRs (short tandem repeats) and by sequencing the hypervariable region I (HV1) of the mitochondrial DNA. The resulting STR profile, mitochondrial haplotype, and haplogroup were compared with data from modern Eurasian and northern native American populations and were found only in European populations historically influenced by ancient nomadic tribes of Central Asia.

    The oldest contemporary human mitochondrial lineages arose in Africa. The earliest divergent extant maternal offshoot, namely haplogroup L0d, is represented by click-speaking forager peoples of southern Africa. Broadly defined as Khoesan, contemporary Khoesan are today largely restricted to the semidesert regions of Namibia and Botswana, whereas archeological, historical, and genetic evidence promotes a once broader southerly dispersal of click-speaking peoples including southward migrating pastoralists and indigenous marine-foragers. No genetic data have been recovered from the indigenous peoples that once sustained life along the southern coastal waters of Africa prepastoral arrival. In this study we generate a complete mitochondrial genome from a 2,330-year-old male skeleton, confirmed through osteological and archeological analysis as practicing a marine-based forager existence. The ancient mtDNA represents a new L0d2c lineage (L0d2c1c) that is today, unlike its Khoe-language based sister-clades (L0d2c1a and L0d2c1b) most closely related to contemporary indigenous San-speakers (specifically Ju). Providing the first genomic evidence that prepastoral Southern African marine foragers carried the earliest diverged maternal modern human lineages, this study emphasizes the significance of Southern African archeological remains in defining early modern human origins.

  20. Aquatic macroinvertebrate responses to native and non-native predators

    Full Text Available Non-native species can profoundly affect native ecosystems through trophic interactions with native species. Native prey may respond differently to non-native versus native predators since they lack prior experience. Here we investigate antipredator responses of two common freshwater macroinvertebrates, Gammarus pulex and Potamopyrgus jenkinsi, to olfactory cues from three predators; sympatric native fish (Gasterosteus aculeatus, sympatric native crayfish (Austropotamobius pallipes, and novel invasive crayfish (Pacifastacus leniusculus. G. pulex responded differently to fish and crayfish; showing enhanced locomotion in response to fish, but a preference for the dark over the light in response to the crayfish. P.jenkinsi showed increased vertical migration in response to all three predator cues relative to controls. These different responses to fish and crayfish are hypothesised to reflect the predators’ differing predation types; benthic for crayfish and pelagic for fish. However, we found no difference in response to native versus invasive crayfish, indicating that prey naiveté is unlikely to drive the impacts of invasive crayfish. The Predator Recognition Continuum Hypothesis proposes that benefits of generalisable predator recognition outweigh costs when predators are diverse. Generalised responses of prey as observed here will be adaptive in the presence of an invader, and may reduce novel predators’ potential impacts.

  1. The characterization of Helicobacter pylori DNA associated with ancient human remains recovered from a Canadian glacier.

    Directory of Open Access Journals (Sweden)

    Treena Swanston

    Full Text Available Helicobacter pylori is a gram-negative bacterium that colonizes the stomach of nearly half of the world's population. Genotypic characterization of H. pylori strains involves the analysis of virulence-associated genes, such as vacA, which has multiple alleles. Previous phylogenetic analyses have revealed a connection between modern H. pylori strains and the movement of ancient human populations. In this study, H. pylori DNA was amplified from the stomach tissue of the Kwäday Dän Ts'ìnchi individual. This ancient individual was recovered from the Samuel Glacier in Tatshenshini-Alsek Park, British Columbia, Canada on the traditional territory of the Champagne and Aishihik First Nations and radiocarbon dated to a timeframe of approximately AD 1670 to 1850. This is the first ancient H. pylori strain to be characterized with vacA sequence data. The Tatshenshini H. pylori strain has a potential hybrid vacA m2a/m1d middle (m region allele and a vacA s2 signal (s region allele. A vacA s2 allele is more commonly identified with Western strains, and this suggests that European strains were present in northwestern Canada during the ancient individual's time. Phylogenetic analysis indicated that the vacA m1d region of the ancient strain clusters with previously published novel Native American strains that are closely related to Asian strains. This indicates a past connection between the Kwäday Dän Ts'ìnchi individual and the ancestors who arrived in the New World thousands of years ago.

  2. Ancient Persian Skywatching and Calendars

    Science.gov (United States)

    Sołtysiak, Arkadiusz

    The peoples of Iran used lunisolar calendars until the early fifth century BCE when the 365-day calendar with 30 months and 5 epagomenal days was introduced. This calendar was not corrected to the actual length of the tropical year, and therefore, seasonal festivals gradually moved away from their seasons. Finally, around the turn of the fifth century CE, a partially successful calendar reform was undertaken, and the feasts were restored to their original seasons. In that time, Sasanian kings were interested in astrology, and some Greek and Hindu astrological texts were translated into Persian, but there is no evidence of indigenous contributions to skywatching.

    Concentrations of metabolic lead in buried ancient bones are obscured by replacement of calcium in apatite by excessive amounts of soil moisture Pb. Concentrations of metabolic barium in bones are affected in a similar way. Added soil Pb and Ba, expressed as log(Pb/Ca) versus log(Ba/Ca) among various bones at a given burial site, are positively covariant, with about 5-fold more soil Pb added for each unit of added soil Ba. The typical natural metabolic Ba/Ca ratio in contemporary people can be measured unambiguously because it as unaffected by industrial pollution. It applies to ancient people because it has not changed historically. The intercept of the covariance curve for buried bones of a given ancient population at the known metabolic Ba/Ca ratio indexes the corresponding metabolic Pb/Ca ratio in bones of that population. Lead levels which prevailed in Romans appear to have been similar to those in contemporary people, which are approximately 1000-fold above natural levels in humans determined by this method in ancient Peruvians. This indicates that studies of natural biochemical reactions in cells free of industrial Pb should be made, because most present biochemical knowledge is founded on data obtained from systems polluted with Pb 1000 to 100000-fold above natural levels. The 5000 year history of smelting Pb by humans indicates that a system of education fostered by genetically common lower brain center functions operated on hundreds of successive generations in a context of cultural changes invoked by feedback from developments in engineering technologies to give rise to the difference between present typical and prehistoric natural levels of Pb in humans. Archaeological and anthropological studies of early developments in writing, music and metallurgy by ancient Peruvians and Persian peoples should be combined with PET-scan studies of their descendants to discover if, as preliminary archaeological data suggest, the two ancient populations differed on a

  4. The Ancient Martian Climate System

    Haberle, Robert M.

    2014-01-01

    Today Mars is a cold, dry, desert planet. The atmosphere is thin and liquid water is not stable. But there is evidence that very early in its history it was warmer and wetter. Since Mariner 9 first detected fluvial features on its ancient terrains researchers have been trying to understand what climatic conditions could have permitted liquid water to flow on the surface. Though the evidence is compelling, the problem is not yet solved. The main issue is coping with the faint young sun. During the period when warmer conditions prevailed 3.5-3.8 Gy the sun's luminosity was approximately 25% less than it is today. How can we explain the presence of liquid water on the surface of Mars under such conditions? A similar problem exists for Earth, which would have frozen over under a faint sun even though the evidence suggests otherwise. Attempts to solve the "Faint Young Sun Paradox" rely on greenhouse warming from an atmosphere with a different mass and composition than we see today. This is true for both Mars and Earth. However, it is not a straightforward solution. Any greenhouse theory must (a) produce the warming and rainfall needed, (b) have a plausible source for the gases required, (c) be sustainable, and (d) explain how the atmosphere evolved to its present state. These are challenging requirements and judging from the literature they have yet to be met. In this talk I will review the large and growing body of work on the early Mars climate system. I will take a holistic approach that involves many disciplines since our goal is to present an integrated view that touches on each of the requirements listed in the preceding paragraph. I will begin with the observational evidence, which comes from the geology, mineralogy, and isotopic data. Each of the data sets presents a consistent picture of a warmer and wetter past with a thicker atmosphere. How much warmer and wetter and how much thicker is a matter of debate, but conditions then were certainly different than

    2013-12-01

    This letter is a call for DNA testing on ancient skeletal materials from the southern Levant to begin a database of genetic information of the inhabitants of this crossroads region. In this region, during the Iron I period traditionally dated to circa 1200-1000 BCE, archaeologists and biblical historians view the earliest presence of a group that called itself Israel. They lived in villages in the varied hill countries of the region, contemporary with urban settlements in the coastal plains, inland valleys, and central hill country attributed to varied indigenous groups collectively called Canaanite. The remnants of Egyptian imperial presence in the region lasted until around 1150 BCE, postdating the arrival of an immigrant group from the Aegean called the Philistines circa 1175 BCE. The period that follows in the southern Levant is marked by the development of territorial states throughout the region, circa 1000-800 BCE. These patrimonial kingdoms, including the United Kingdom of Israel and the divided kingdoms of northern Israel and Judah, coalesced varied peoples under central leadership and newly founded administrative and religious bureaucracies. Ancient DNA testing will give us a further refined understanding of the individuals who peopled the region of the southern Levant throughout its varied archaeological and historic periods and provide scientific data that will support, refute, or nuance our sociohistoric reconstruction of ancient group identities. These social identities may or may not map onto genetic data, but without sampling of ancient DNA we may never know. A database of ancient DNA will also allow for comparisons with modern DNA samples collected throughout the greater region and the Mediterranean littoral, giving a more robust understanding of the long historical trajectories of regional human genetics and the genetics of varied ancestral groups of today's Jewish populations and other cultural groups in the modern Middle East and Mediterranean

    1. Native parasite acquisition provides introduced species with the potential to modify native host-parasite dynamics by acting as parasite reservoirs (with the 'spillback' of infection increasing the parasite burdens of native hosts) or sinks (with the 'dilution' of infection decreasing the parasite burdens of native hosts) of infection. 2. In New Zealand, negative correlations between the presence of introduced brown trout (Salmo trutta) and native parasite burdens of the native roundhead galaxias (Galaxias anomalus) have been observed, suggesting that parasite dilution is occurring. 3. We used a multiple-scale approach combining field observations, experimental infections and dynamic population modelling to investigate whether native Acanthocephalus galaxii acquisition by brown trout alters host-parasite dynamics in native roundhead galaxias. 4. Field observations demonstrated higher infection intensity in introduced trout than in native galaxias, but only small, immature A. galaxii were present in trout. Experimental infections also demonstrated that A. galaxii does not mature in trout, although parasite establishment and initial growth were similar in the two hosts. Taken together, these results support the hypothesis that trout may serve as an infection sink for the native parasite. 5. However, dynamic population modelling predicts that A. galaxii infections in native galaxias should at most only be slightly reduced by dilution in the presence of trout. Rather, model exploration indicates parasite densities in galaxias are highly sensitive to galaxias predation on infected amphipods, and to relative abundances of galaxias and trout. Hence, trout presence may instead reduce parasite burdens in galaxias by either reducing galaxias density or by altering galaxias foraging behaviour. PMID:21426342

  8. PIXE analysis on an ancient scroll sample

    International Nuclear Information System (INIS)

    For years, scientists have developed several new techniques to read texts of Herculaneum scrolls without destroying them. Recently, the use of a custom built high-resolution CT scanner was proposed to scan and then virtually unroll the scrolls for reading. Identification of any unique chemical signatures in the ancient ink would allow better calibration of the CT scanner to improve the chances of resolving the ink from the burned papyrus background. To support this effort, we carried out one pilot study to see whether the composition of the ink can be obtained from an ancient scroll sample using PIXE technique. PIXE data were collected and analyzed in two different regions of the ancient scroll sample (ink and blank regions). This preliminary work shows that elemental distributions from the ink used in this scroll mainly contained Al, Fe and Ti as well as minor trace amounts of Cr, Cu and Zn. (author)

    The ancient Chinese notes on hydrogeology are summarized and interpreted, along with records of some related matters, like groundwater exploration and utilization, karst springs, water circulation, water conservation and saline-land transformation, mine drainage, and environmental hydrogeology. The report focuses only on the earliest recorded notes, mostly up until the Han Dynasty (206 BC - AD 25). Besides the references cited, the discussion in this report is based mainly on archaeological material, the preserved written classic literature, and some assumptions and/or conclusions that have been handed down in legends to later ages. Although most material relates to ancient China, the lessons learned may have practical significance worldwide. Compared to other contemporary parts of the world, ancient China, without doubt, took the lead in the field of groundwater hydrology. The great achievements and experience of the Chinese ancestors should provide motivation and inspiration for hydrogeologists to carry out their scientific research and exploration passionately and actively.

  10. Twins in Ancient Greece: a synopsis.

    Malamitsi-Puchner, Ariadne

    2016-01-01

    This brief outline associates twins with several aspects of life in Ancient Greece. In Greek mythology twins caused ambivalent reactions and were believed to have ambivalent feelings for each other. Very often, they were viewed as the representatives of the dualistic nature of the universe. Heteropaternal superfecundation, which dominates in ancient myths, explains on one hand, the god-like qualities and, on the other hand, the mortal nature of many twins. An assumption is presented that legends referring to twins might reflect the territorial expansions of Ancient Greeks in Northern Mediterranean, around the Black Sea, in Asia Minor, as well as North East Africa. In conclusion, in Greek antiquity, twins have been used as transitional figures between myth and reality. PMID:26135766

    Fabritius discovered the first variable star, Mira, in 1596. Holwarda determined the 11 months period of Mira in 1638. Montanari discovered the next variable star, Algol, in 1669. Its period, 2.867 days, was determined by Goodricke (178). Algol was associated with demon-like creatures, "Gorgon" in ancient Greek and "ghoul" in ancient Arab mythology. This indicates that its variability was discovered much before 1669 (Wilk 1996), but this mythological evidence is ambiguous (Davis 1975). For thousands of years, the Ancient Egyptian Scribes (AES) observed stars for timekeeping in a region, where there are nearly 300 clear nights a year. We discovered a significant periodicity of 2.850 days in their calendar for lucky and unlucky days dated to 1224 BC, "the Cairo Calendar". Several astrophysical and astronomical tests supported our conclusion that this was the period of Algol three millennia ago. The "ghoulish habits" of Algol could explain this 0.017 days period increase (Battersby 2012).

    James, O. B.

    1992-01-01

    The Apollo 17 highland collection is dominated by fragment-laden melt rocks, generally thought to represent impact melt from the Serenitatis basin-forming impact. Fortunately for our understanding of the lunar crust, the melt rocks contain unmelted clasts of preexisting rocks. Similar ancient rocks are also found in the regolith; most are probably clasts eroded out of melt rocks. The ancient rocks can be divided into groups by age, composition, and history. Oldest are plutonic igneous rocks, representing the magmatic components of the ancient crust. The younger are granulitic breccias, which are thoroughly recrystallized rocks of diverse parentages. The youngest are KREEPy basalts and felsites, products of relatively evolved magmas. Some characteristics of each group are given.

  13. The Geoscience Alliance--A National Network for Broadening Participation of Native Americans in the Geosciences

    Dalbotten, D. M.; Berthelote, A. R.

    2014-12-01

    The Geoscience Alliance is a national alliance of individuals committed to broadening participation of Native Americans in the geosciences. Native Americans in this case include American Indians, Alaska Natives and people of Native Hawai'ian ancestry. Although they make up a large percentage of the resource managers in the country, they are underrepresented in degrees in the geosciences. The Geoscience Alliance (GA) members are faculty and staff from tribal colleges, universities, and research centers; native elders and community members; industry, agency, and corporate representatives; students (K12, undergraduate, and graduate); formal and informal educators; and other interested individuals. The goals of the Geoscience Alliance are to 1) create new collaborations in support of geoscience education for Native American students, 2) establish a new research agenda aimed at closing gaps in our knowledge on barriers and best practices related to Native American participation in the geosciences, 3) increase participation by Native Americans in setting the national research agenda on issues in the geosciences, and particularly those that impact Native lands, 4) provide a forum to communicate educational opportunities for Native American students in the geosciences, and 5) to understand and respect indigenous traditional knowledge. In this presentation, we look at the disparity between numbers of Native Americans involved in careers related to the geosciences and those who are receiving bachelors or graduate degrees in the geosciences. We address barriers towards degree completion in the geosciences, and look at innovative programs that are addressing those barriers.

    With intensifying demands for food and biofuels, a critical threat to biodiversity is agricultural expansion into native tropical ecosystems. Tropical agriculture, particularly intensive agriculture, often supports few native organisms, and consequently has been largely overlooked in conservation planning; yet, recent work in the Neotropics demonstrates that tropical agriculture with certain features can support significant biodiversity, decades after conversion to farmland. It remains unknow...

    Neither public opinion nor evidence-based research supports the claim of some politicias and the media that immigrants take the jobs of native-born workers. Public opinion polls in six migrant-destination countries after the 2008–2009 recession show that most people believe that immigrants fill job vacancies and many believe that they create jobs and do not take jobs from native workers. This view is corroborated by evidence-based research showing that immigrants—of all skill levels—do not si...

  17. Symmetries in Images on Ancient Seals

    CERN Document Server

    Sparavigna, Amelia

    2008-01-01

    In this paper, we discuss the presence of symmetries in images engraved on ancient seals, in particular on stamp seals. Mainly used to secure the containers from tampering and for owner's identification, these objects appeared during the 5th millennium BC in Mesopotamia. Usually the seals were engraved with simple images, suitable to communicate an immediate information. Rotational symmetries are already displayed by the most ancient stamp seals, whose images reach a quasi-perfect symmetry in their small circular or ovoid spaces. Bilateral symmetries are quite common in Egyptian scarab seals.

    2013-01-01

    Full Text Available Neurilemmomas are benign tumors of neural origin composed of Schwann cell proliferation in characteristic patterns. Ancient neurilemmomas are usually longstanding growths that exhibit degenerative features that could be mistaken for malignancy. They are extremely rare in the oral cavity and present in older individuals of long duration. The authors report a case of ancient neurilemmoma in a young patient with short duration of growth. This unique case presented with remarkable histopathological features with respect to vascularity and atypia associated with degenerative change. It is essential to not mistake these features as malignant transformation so as to avoid radical procedures.

  19. The TL dating of ancient porcelain

    International Nuclear Information System (INIS)

    The age determination of ancient porcelain using the pre-dose technique in TL dating was reported. The variation of beta dose with depth below the surface of the porcelain slice, the thermal activation characteristic (TAC) for 110 degree C peak, the measurement of paleodose and the estimation of annual dose were studied. The results show that this technique is suitable for authenticity testing of ancient porcelain, but both accuracy and precision for porcelain dating are worse than those for pottery, because porcelain differs from pottery on composition, structure and firing temperature. Besides, some complicated factors in the pre-dose technique would be the possible cause of the greater errors

The analytical method is right for this type of study because it is a nondestructive technique, however, the sample procedure is destructive, besides being highly sensitivity, accuracy and precision to determine chemical elements in trace and ultra trace levels. To study the data set multivariate statistical analysis techniques were used. Initially the concentrations were normalized using log base 10. Following the outliers were studied by means of Mahalanobis distance. Finally the data were interpreted by means of components analysis and discriminant analysis. (author)

    We report here the genome sequence of an ancient human. Obtained from ∼4,000-year-old permafrost-preserved hair, the genome represents a male individual from the first known culture to settle in Greenland. Sequenced to an average depth of 20×, we recover 79% of the diploid genome, an amount close to the practical limit of current sequencing technologies. We identify 353,151 high-confidence single-nucleotide polymorphisms (SNPs), of which 6.8% have not been reported previously. We estimate raw read contamination to be no higher than 0.8%. We use functional SNP assessment to assign possible phenotypic characteristics of the individual that belonged to a culture whose location has yielded only trace human remains. We compare the high-confidence SNPs to those of contemporary populations to find the populations most closely related to the individual. This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit. PMID:20148029

    Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. We combined ancient DNA sequences of wild and early-domesticated dromedary samples from arid regions with nuclear microsatellite and mitochondrial genotype information from 1,083 extant animals collected across the species’ range. We observe little phylogeographic signal in the modern population, indicative of extensive gene flow and virtually affecting all regions except East Africa, where dromedary populations have remained relatively isolated. In agreement with archaeological findings, we identify wild dromedaries from the southeast Arabian Peninsula among the founders of the domestic dromedary gene pool. Approximate Bayesian computations further support the “restocking from the wild” hypothesis, with an initial domestication followed by introgression from individuals from wild, now-extinct populations. Compared with other livestock, which show a long history of gene flow with their wild ancestors, we find a high initial diversity relative to the native distribution of the wild ancestor on the Arabian Peninsula and to the brief coexistence of early-domesticated and wild individuals. This study also demonstrates the potential to retrieve ancient DNA sequences from osseous remains excavated in hot and dry desert environments. PMID:27162355

    The ancient documents present an important part of our individual and collective memory. In addition to their preservation, the digitization of these documents may offer users a great number of services like remote look-up and browsing rare documents. However, the documents, digitally formed, are likely to be modified or pirated. Therefore, we need to develop techniques of protecting images stemming from ancient documents. Watermarking figures to be one of the promising solutions. Nevertheless, the performance of watermarking procedure depends on being neither too robust nor too invisible. Thus, choosing the insertion field or mode as well as the carrier points of the signature is decisive. We propose in this work a method of watermarking images stemming from ancient documents based on wavelet packet decomposition. The insertion is carried out into the maximum amplitude ratio being in the best base of decomposition, which is determined beforehand according to a criterion on entropy. This work is part of a project of digitizing ancient documents in cooperation with the National Library of Tunis (BNT).

  18. Defining Astrology in Ancient and Classical History

    Campion, Nicholas

    2015-05-01

    Astrology in the ancient and classical worlds can be partly defined by its role, and partly by the way in which scholars spoke about it. The problem is complicated by the fact that the word is Greek - it has no Babylonian or Egyptian cognates - and even in Greece it was interchangeable with its cousin, 'astronomy'. Yet if we are to understand the role of the sky, stars and planets in culture, debates about the nature of ancient astrology, by both classical and modern scholars, must be taken into account. This talk will consider modern scholars' typologies of ancient astrology, together with ancient debates from Cicero in the 1st century BC, to Plotinus (204/5-270 AD) and Isidore of Seville (c. 560 - 4 April 636). It will consider the implications for our understanding of astronomy's role in culture, and conclude that in the classical period astrology may be best understood through its diversity and allegiance to competing philosophies, and that its functions were therefore similarly varied.

    The Pet6n region of northern Guatemala contains some of the most significant Mayan archeological sites in Latin America. It was in this region that the Maya civilization began, flourished, and abruptly disappeared. Remote sensing technology is helping to locate and map ancient Maya sites that are threatened today by accelerating deforestation and looting. Thematic Mapper, IKONOS, and QuickBird satellite, and airborne STAR-3i and AIRSAR radar data, combined with Global Positioning System (GPS) technology, are successfully detecting ancient Maya features such as sites, roadways, canals, and water reservoirs. Satellite imagery is also being used to map the bajos, which are seasonally flooded swamps that cover over 40% of the land surface. Through the use of various airborne and satellite sensor systems we have been able to detect and map ancient causeways, temples, reservoirs, and land forms, and locate these features on the ground through GPS technology. Recently, we have discovered that there is a strong relationship between a tropical forest vegetation signature in satellite imagery and the location of archeological sites. We believe that the use of limestone and lime plasters in ancient Maya construction affects the moisture, nutrition, and plant species of the surface vegetation. We have mapped these vegetation signatures in the imagery and verified through field survey that they are indicative of archeological sites. Through the use of remote sensing and GIS technology it is possible to identify unrecorded archeological features in a dense tropical forest environment and monitor these cultural features for their protection.

    Full Text Available On our planet time flows evenly everywhere but the history as weknow it has different length and depth in every place. Maybe thedeepest layer of history lies in the land between Tigris and Eufrat –Mesopotamia (Greek ‘the land between two rivers’. Itis hard to grasp how much our current culture has inherited fromthe people of that land – be it either the wheel, the art of writing,or the units for measuring time and angles. Science and knowledgeof stars has always – though with varying success – been importantin European culture. Much from the Babylonian beliefs about constellationsand planets have reached our days. Planets had an importantplace in Babylonian astral religion, they were observed asmuch for calendrical as astrological purposes, and the qualities ofthe planetary gods were carried on to Greek and Rome.The following started out as an attempt to compose a list of planetstogether with corresponding gods who lend their names and qualitiesto the planets. Though it was easy to find such a list aboutGreece and Rome, texts concerning Mesopotamia included miscellaneousfacts subdivided into general categories only (e.g. Pannekoek1961. The reasons of this vagueness later became evident with thecompiling of such a table starting to look like Sisyphean work.

    This paper examines the inception and development of the Ancient Greek Cities (AGC) research project (1963–77) of Constantinos A. Doxiadis and addresses the novelty of its methodological approach to the study of classical urbanism. With the AGC project, Doxiadis launched a comprehensive study of the ancient Greek built environment to provide an overview of the factors involved in its shaping. The project produced 24 published volumes — the first two laying out the historical and methodologica...

  9. Ancient Egypt in our Cultural Heritage?

    Full Text Available Inspiration derived from ancient Egypt is usually expressed through the Egyptian motifs in arts and popular culture of the 19th and 20th centuries, as well as through the non-scientific interpretations of the culture, very much based upon the Renaissance ones. The number and variety of material and non-material traces of this fascination are most expressed in the countries where, along with the early support for the institutional development of Egyptology, there existed economically potent educated middle classes (Western and Central Europe, USA, but may also be traced elsewhere. The public fascination by ancient Egypt has not ceased by the times of foundation of Egyptology, marked by the decipherment of the hieroglyphic script in 1822. Until the end of the 20th century Egyptologists have rarely dealt with the prelude to their discipline, limiting their interest to the critical approach to ancient sources and to noting the attempts to interpret the hieroglyphic script and the function of pyramids. However, the rising importance of the reception studies in other disciplines raised the interest of Egyptologists for the "fascination of Egypt", thus changing the status of various modes of expressing "Egyptomania" – they have thus become a part of the cultural heritage, registered, documented, preserved and studied. The research of this kind is only beginning in Serbia. The line of inquiry enhances the knowledge of the scope, manifestations and roles of the interest in Egypt, not limited by the national or political borders. On the other hand, the existence of the cultural heritage similar to the wider European view of ancient Egypt – short remarks by Jerotej Račanin, Kandor by Atanasije Stojković, the usage of architectural motifs derived from Egypt, the emergence of small private collections, to mention several early examples – all show that the research into the reception of ancient Egypt may contribute to the knowledge about the history

  10. Genetic diversity among ancient Nordic populations.

    Linea Melchior

    Full Text Available Using established criteria for work with fossil DNA we have analysed mitochondrial DNA from 92 individuals from 18 locations in Denmark ranging in time from the Mesolithic to the Medieval Age. Unequivocal assignment of mtDNA haplotypes was possible for 56 of the ancient individuals; however, the success rate varied substantially between sites; the highest rates were obtained with untouched, freshly excavated material, whereas heavy handling, archeological preservation and storage for many years influenced the ability to obtain authentic endogenic DNA. While the nucleotide diversity at two locations was similar to that among extant Danes, the diversity at four sites was considerably higher. This supports previous observations for ancient Britons. The overall occurrence of haplogroups did not deviate from extant Scandinavians, however, haplogroup I was significantly more frequent among the ancient Danes (average 13% than among extant Danes and Scandinavians (approximately 2.5% as well as among other ancient population samples reported. Haplogroup I could therefore have been an ancient Southern Scandinavian type "diluted" by later immigration events. Interestingly, the two Neolithic samples (4,200 YBP, Bell Beaker culture that were typed were haplogroup U4 and U5a, respectively, and the single Bronze Age sample (3,300-3,500 YBP was haplogroup U4. These two haplogroups have been associated with the Mesolithic populations of Central and Northern Europe. Therefore, at least for Southern Scandinavia, our findings do not support a possible replacement of a haplogroup U dominated hunter-gatherer population by a more haplogroup diverse Neolithic Culture.

  11. [A review of the principle mythical gods in ancient greek medicine].

    2014-12-01

    Like their prehistoric ancestors, the people of early civilizations lived related to the supernatural. Facing life-threatening situations, such as illness and death, people of ancient civilizations resorted to divination, prophecy, or the oracle. Regarding the curative activities of the ancient Greek civilization, there was a period in which these processes were exclusively linked to a supernatural perspective of the origin of disease. This stage of development of Greek healing practices corresponds to what might be called pre-Hippocratic Greek medicine. In ancient Greek civilization, myths exerted a strong influence on the concepts of disease and the healing processes. Although the first divine figure of Greek mythology related to medicine was Paeon, healing cults related to Apollo and Asclepius had a higher importance in tradition and Greek mythology. The Apollonian divine healing consisted in the ability to eliminate chaos and keep away evil, while in the Asclepian perspective, the role of healer was linked to specific procedures. Personal and medical skills allowed Asclepius to surpass his father and achieve his final consecration as a god of medicine. PMID:25643892

    2010-09-01

    Every part of the world is characterized by his own climatological peculiarities, and sometimes some restricted areas can be influenced by local, singular, characteristical metereological phenomena. Trieste, capital of the region Friuli Venezia Giulia, and the Karst ( northeastern Italy) are included in this category. Since the old age it has been narrated the "raids" caused by the Bora, strong dry and cold north eastern wind that, with one of his most northern branch, which born in the karstic inland near Postumia (Slovenia), affects the Karst plateau and the Gulf of Trieste. In literature we can find how on September 5th, 394 a.C. the "miraculous wind" Bora has been decisive for the defeat of Arbogaste (West Roman Empire) in the Vipavska valley; he was with his army against the wind in the battle whereas the troops of the Catholic Emperor Teodosio (East Roman Empire) has been able to through their darts further thank to the wind. The fairy tales about "Bora" and "Borino" are part of the local literature since many centuries, whereas in the XX Century we can find images, postcards and books concerning the tempestuous wind of Trieste. When television born, developed a new way to communicate the deeds of Bora thanks to some extreme events occurred among 30s and 50s which contributes to increase his mith. The goal of this work is to retrace the history of Bora in the words of the common people rather than the science in order to understand how his legend has grown during the ages. Now, in the age of internet, a new way of telling the Bora adventures is born.

    How and when the Americas were populated remains contentious. Using ancient and modern genome-wide data, we find that the ancestors of all present-day Native Americans, including Athabascans and Amerindians, entered the Americas as a single migration wave from Siberia no earlier than 23 thousand years ago (KYA), and after no more than 8,000-year isolation period in Beringia. Following their arrival to the Americas, ancestral Native Americans diversified into two basal genetic branches around 13 KYA, one that is now dispersed across North and South America and the other is restricted to North America. Subsequent gene flow resulted in some Native Americans sharing ancestry with present-day East Asians (including Siberians) and, more distantly, Australo-Melanesians. Putative ‘Paleoamerican’ relict populations, including the historical Mexican Pericúes and South American Fuego-Patagonians, are not directly related to modern Australo-Melanesians as suggested by the Paleoamerican Model.

  19. How native-like is non-native language processing?

    Science.gov (United States)

    Clahsen, Harald; Felser, Claudia

    2006-12-01

    Following several decades of research on native language (L1) processing, psycholinguists have more recently begun to investigate how non-native language (L2) speakers comprehend and process language in real time. Regarding the traditional assumption that L2 learners have 'difficulty with grammar', this new research has revealed some unexpected similarities and differences between L1 and L2 processing. Specifically, it appears that L2 processing can become native-like in some linguistic subdomains (including certain aspects of grammar) but that L1 and L2 processing differences persist in the domain of complex syntax, even in highly proficient L2 speakers. Thus, more subtle linguistic distinctions seem to be required to understand the nature of non-native language processing. PMID:17071131

  20. Literature review and ethnohistory of Native American occupancy and use of the Yucca Mountain Region

    International Nuclear Information System (INIS)

    This report presents a review of the literature concerning Native American occupancy and use of the Yucca Mountain area and vicinity. It draws on a wide range of material, including early traveler reports, government documents, ethnographic and historical works, and local newspapers. The report complements two other concurrent studies, one focused on the cultural resources of Native American people in the study area and the other an ethnobotanical study of plant resources used by Native American people in the study area. The literature review has had two principal purposes: to determine the completeness of the Yucca Mountain Native American study design and to contribute to the understanding of the presence of Native American people in the Yucca Mountain area. A review of the existing literature about the Yucca Mountain area and southern Nye County, supplemented by the broader literature about the Great Basin, has verified three aspects of the study design. First, the review has aided in assessing the completeness of the list of Native American ethnic groups that have traditional or historical ties to the site. Second, it has aided in the production of a chronology of Native American activities that occurred on or near the site during the late nineteenth and early twentieth centuries. Third, it has helped to identify the location of cultural resources, including burials and other archaeological sites, in the study area and vicinity. 200 refs., 16 figs., 6 tabs

    Full Text Available Native advertising is described both as a new way for promoters to engage audiences and as a new, clever, source of revenue for publishers and media agencies. The debates around its morality and the need for a wide accepted framework are often viewed as calls for creativity. Aside from the various forms, strategies and the need for clarification, the fact that native advertising works and its revenue estimates increase annually transforms the new type of ad into a clear objective for companies, marketers and publishers. Native advertising stopped being a buzzword and started being a marketing reality.

    Full Text Available Studies done on Colombia’s population history during the last three decades have been influenced by the ideas, methods and approaches of Woodrow Borah. We will discuss three issues that he and Sherburne Cook considered in the course of their work on Latin American demography – probable size of native populations on the eve of European contact; the effects of climate and elevation on the intensity of different groups’ decline; and the impact on native populations of diseases brought from the Old World to the New. We examine the information available on Colombia’s diverse highland and lowland regions, and in that context explore questions that have arisen recently regarding nutrition and health levels of native people prior to European conquest.

    Los estudios que se han realizado sobre la historia demográfica de Colombia durante las tres últimas décadas se han visto influidos por las ideas, métodos y planteamientos de Woodrow Borah. Discutiremos tres aspectos que él y Sherburne Cook han tenido en cuenta a lo largo de sus trabajos sobre la demografía latinoamericana: el volumen de la población nativa en vísperas del contacto con los europeos; los efectos del clima y de la altitud en el declive de la intensidad demográfica de los diferentes grupos; y el impacto en la población nativa de las enfermedades procedentes del Viejo Mundo. Examinamos la información disponible en el altiplano y en la zona costera de Colombia y, en dicho contexto, valoramos cuestiones que han surgido recientemente con relación a los niveles de nutrición y salud de la población nativa antes de la conquista europea.

    There are an estimated 4.1 million people who are classified as American Indian and Alaska Native alone or in combination with one or more other races. This racial group composes 1.5% of the total U.S. population. The leading causes of illness and death among American Indians are heart disease, cancer, unintentional injuries (accidents), diabetes, and stroke. American Indians also have a high prevalence of obesity, chronic renal failure, alcoholism, and are at increased risk for mental health issues and suicide. In an effort to build a trusted relationship with these patients and become an active participant in their care, the health care provider must demonstrate respect for the traditions of the American Indian.

  15. Thermal and spectroscopic analysis of ancient potteries

    International Nuclear Information System (INIS)

    The present work is focused on the characterization study of ancient pottery shreds excavated recently from Sembiankandiyur in India. The study is intended to identify the firing temperature, firing conditions and morphology of the ancient pottery samples. The samples were analyzed using FTIR, XRD and TG-DTA. FTIR and XRD studies were used in mineralogical characterization of potteries. The firing temperature and conditions were interpreted by studying the difference in mineral composition in the samples using FTIR and XRD. TG-DTA is considered the complementary technique to elucidate the firing temperature from the thermal characteristic reactions such as dehydration, decomposition and transformations of minerals in the course of controlled firing of the samples. The results showed that all the samples fired in a oxidizing condition and firing temperature also inferred.(authors)

In order to explain the doubts of the ancient Olympic Games, the paper analyses the doubts, such as failure of swimming to be the competition item, advantages and disadvantages of Sparta and Athens educational system and definition of competition content. The paper reveals that swimming failed to be one of the Olympic sports items because of the special national personality of the ancient Greeks and the special demands of the swimming spot. The ancient Sparta education is a practical education according to the national features of the Sparta people. Clear recognition of Ancient Olympia fiesta and the connotation of the ancient Olympic sport competition is the precondition of defining the content of the ancient Olympic Games.

    Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.

    We are living in a definite time of change. Distinct changes are being experienced in our most sacred and natural environments. This is especially true on Native lands. Native people have lived for millennia in distinct and unique ways. The knowledge of balancing the needs of people with the needs of our natural environments is paramount in all tribal societies. This inherent knowledge has become the foundation on which to build a "blended" contemporary understanding of western science. The Dakota's and Northern California have recognized the critical need in understanding successful tribal strategies to engage educational systems (K-12 and higher education), to bring to prominence the professional development opportunities forged through working with tribal peoples and ensure the growth of Native people in STEM (Science, Technology, Engineering and Mathematics) professions. The presentation will highlight: 1) current philosophies on building a STEM Native workforce; 2) successful educational programs/activities in PreK-Ph.D. systems; 3) current Native professionals, their research and tribal applicability; and 4) forwarding thinking for creating sustainable environmental and social infrastructures for all people. South Dakota School of Mines and Technology (SDSM&T) and Humboldt State University (HSU) have been recognized nationally for their partnerships with Native communities. SDSM&T has set record numbers for graduating Native students in science and engineering. SDSM&T had 27 graduates in five years (2000-2005) and hosted more than 1000+ Native students for programs and activities. Humboldt State University is the only university in the CSU system with a program focusing specifically on Natives in natural resources, science and engineering as well as a Native American Studies degree. Both universities have designed programs to meet current needs and address challenging issues in Earth, Wind, Fire and Water. The programs are funded through NASA, NSF, NIH and

    Health-care parameters for Natives living in isolated northern areas of Canada show rates of life expectancy, morbidity, and infant mortality far worse than the Canadian average. Improving access to medical facilities has not affected these statistics. Socioeconomic factors such as inadequate housing and lack of sewage systems are likely contributors to poor health, as is an attitude of hopelessness and impotence on the part of Native people.

    Many Native American communities recognize that the retention of their language, and the need to make the language relevant to the technological age we live in, represents one of their largest and most urgent challenges. Almost 70 percent of Navajos speak their tribal language in the home, and 25 per cent do not know English very well. In contrast, only 30 percent of Native Americans as a whole speak their own tribal language in the home. For the Cherokee and the Chippewa, less than 10 percent speak the native language in the home. And for the Navajo, the number of first graders who solely speak English is almost four times higher than it was in 1970. The U.S. Rosetta Project is the NASA contribution to the International Rosetta Mission. The Rosetta stone is the inspiration for the mission’s name. As outlined by the European Space Agency, Rosetta is expected to provide the keys to the primordial solar system the way the original Rosetta Stone provided a key to ancient language. The concept of ancient language as a key provides a theme for this NASA project’s outreach to Native American communities anxious for ways to enhance and improve the numbers of native speakers. In this talk we will present a concept for building on native language as it relates to STEM concepts. In 2009, a student from the Dine Nation interpreted 28 NASA terms for his senior project at Chinle High School in Chinle, AZ. These terms included such words as space telescope, weather satellite, space suit, and the planets including Neptune and Uranus. This work represents a foundation for continued work between NASA and the Navajo Nation. Following approval by the tribal elders, the U.S. Rosetta project would host the newly translated Navajo words on a web-site, and provide translation into both Navajo and English. A clickable map would allow the user to move through all the words, see Native artwork related to the word, and hear audio translation. Extension to very remote teachers in the

    Evaluation of bone mineral density (BMD) of the ancient peoples has received great interest by anthropologists. The aims of this study are to investigate the lumbar vertebrae of the Iasos people during the Byzantine period, in order to determine the prevalence of bone loss and to interpret dietary conditions of ancient Mediterranean populations. Lumbar vertebrae belonging to twenty eight skeletons of the 6th c AD were analyzed by radiographs and dual energy X-ray absorptiometry. The BMD values for each biologic sex and age group were compared. The correlation between the BMD and radiological features was also analyzed. The mean BMD was 0.940 g/cm2. BMD was decreased by aging in both sexes, but it was not significant. Osteopenia was found in 11 (39%) and osteoporosis in 4 (14.3%) out 28 vertebrae. The BMD was normal in 13 (46%) out of 28 vertebrae. Osteopenia was present in 7 (38%) of 18 male vertebrae and 4 (40%) of 10 female vertebrae. The spine score was high in the male group and there was a strong positive correlation between the BMD and spine score for both sexes. This study revealed that the BMD decreased by aging and that osteopenia was a problem in both sexes of the Iasos people during the 6th c AD. There was no correlation between the BMD and radiological features for age groups and biological sexes.

  10. The Ginseng Growing District, Taxation and Trade in Ancient Korea

    Directory of Open Access Journals (Sweden)

    YANG Jeong-Pil

    2004-12-01

    Full Text Available The very first record of ginseng in the Korean peninsula dates back to early 6th century A.D., with its concentration in Chinese sources. Regardless of the fact that the Korean ginseng was introduced to China before the birth of Christ, there is no writing about it for 500 years. This is because the Chinese substituted Korean ginseng for the Chinese one, which was cultivated around the Shangdang Area. The ginseng, however, is greatly influenced by natural environment and its native area being Manchuria and the Korean peninsula. It is believed that ginseng range from the northern mountains of Pyongando and Hamkyongdo provinces to the southern Taebaek and Sobaek mountains in Korea. Especially the area of Madasan(Baekdusan? mountain was well-known for ginseng-growing district. The ginseng taxation of the Three Kingdoms period seems to have gone through certain changes along the development stages of the ancient state. The first taxation stage is estimated to be in the form of a tribute. Afterwards, as the governing power of central government was gradually strengthened in the subjugated places, there was a major replacement from tributary form to actual goods levy. The actual areas of such tributary collection is unknown, but the [Sejongshilok Chiriji](geographical records of Sejong chronicles of the early Choson era indicates 113 prefectures and counties as those which submit ginseng to the central government. These administrations provide permissible clues to the historic background of ginseng-taxed regions of the Three Kingdoms. The ginseng trade also is estimated to have flourished in ancient Korea through the Han commanderies of China. However, the writings of Korean ginseng trade is non-existent until 6th century A .D., Such phenomenon can be attributed to few reasons. First, the Chinese took little interest in Korean ginseng as they believed they had their own native ginseng in China. Second, same ignorance resulted from its inflowing but

  12. A study on provenance relation between Jiaotanxia ancient Guan porcelain and Qingliangsi ancient Ru porcelain by NAA

    International Nuclear Information System (INIS)

    11 samples of ancient Chinese Ru porcelain from Qingliangsi kiln, 23 samples of ancient Chinese Guan porcelain from Jiaotanxia kiln and 4 samples of modern archaized Guan porcelain were obtained to determine the contents of elements in each of them by neutron activation analysis (NAA). The NAA data were further analyzed using fuzzy cluster analysis to obtain the fuzzy cluster trend diagrams for the bodies' samples and the glazes samples respectively. The analysis shows that the raw material origins of the Jiaotanxia ancient Chinese Guan porcelain bodies samples are very concentrated; those of the Qingliangsi ancient Chinese Ru porcelain bodies samples are a little dispersed; those of ancient Chinese Guan porcelain glazes samples are relatively concentrated; those of ancient Chinese Ru porcelain glazes samples are dispersed; and the origins of the raw material of ancient Chinese Guan porcelain glazes samples are obviously different from those of ancient Chinese Ru porcelain glazes samples. The bodies samples and glazes samples of Jiaotanxia ancient Chinese Guan porcelain and those of Qingliangsi ancient Chinese Ru porcelain have some difference but can be compared with each other.

    2003-12-01

    The digitization of ancient Chinese documents presents new challenges to OCR (Optical Character Recognition) research field due to the large character set of ancient Chinese characters, variant font types, and versatile document layout styles, as these documents are historical reflections to the thousands of years of Chinese civilization. After analyzing the general characteristics of ancient Chinese documents, we present a solution for recognition of ancient Chinese documents with regular font-types and layout-styles. Based on the previous work on multilingual OCR in TH-OCR system, we focus on the design and development of two key technologies which include character recognition and page segmentation. Experimental results show that the developed character recognition kernel of 19,635 Chinese characters outperforms our original traditional Chinese recognition kernel; Benchmarked test on printed ancient Chinese books proves that the proposed system is effective for regular ancient Chinese documents.

  17. Impact of hydroelectric development upon a northern Manitoba native community

    Energy Technology Data Exchange (ETDEWEB)

    Waldram, J.B.

    1983-01-01

    This dissertation describes the process of underdevelopment among the Cree Indian people of South Indian Lake, in Northern Manitoba, Canada, following the construction of the Churchill-Nelson River Hydro Project in 1975. The dissertation seeks to link the ecological, political, economic, socio-cultural and health aspects of the impact of the hydro project within the framework of the historical process of underdevelopment as it has occurred in Latin America, among Native people in the United States, and among Native people in Northern Canada. Utilizing both qualitative and quantitative data, a process of increased dependence is described as the product of two related processes. The first process is the impairment of the local commercial and domestic economy caused by the flooding of Southern Indian Lake, which has resulted in a decline in local productivity. The second process is the enhancement of consumerism through rising consumer expectations and a post-project increase in available goods and services which the people are increasingly unable to afford. The overall result has been a process of economic divergence at the local level. The dissertation concludes that the process of underdevelopment which has occurred in South Indian Lake has been the result primarily of changes in the local ecological system caused by the construction of the hydro project. These ecological changes have, in turn, resulted in secondary changes in the socio-economic system.

    Our native tongue influences the way we perceive other languages. But does it also determine the way we perceive nonlinguistic sounds? The authors investigated how speakers of Italian, Turkish, and Persian group sequences of syllables, tones, or visual shapes alternating in either frequency or duration. We found strong native listening effects with linguistic stimuli. Speakers of Italian grouped the linguistic stimuli differently from speakers of Turkish and Persian. However, speakers of all languages showed the same perceptual biases when grouping the nonlinguistic auditory and the visual stimuli. The shared perceptual biases appear to be determined by universal grouping principles, and the linguistic differences caused by prosodic differences between the languages. Although previous findings suggest that acquired linguistic knowledge can either enhance or diminish the perception of both linguistic and nonlinguistic auditory stimuli, we found no transfer of native listening effects across auditory domains or perceptual modalities.

    Poor DNA preservation is the most limiting factor in ancient genomic research. In the majority of ancient bones and teeth, endogenous DNA molecules represent a minor fraction of the whole DNA extract, rendering shot-gun sequencing inefficient for obtaining genomic data. Based on ancient human bone samples from temperate and tropical environments, we show that an EDTA-based enzymatic ‘pre-digestion’ of powdered bone increases the proportion of endogenous DNA several fold.

    Chinese ancient architectures are valuable heritage of ancient culture of China. Many historical building have been preserved up to now. The researches on the structural mechanics of ancient architectures show the different aspects of structure and mechanics. Systematical studies on the structural mechanics of ancient architectures have been carried out at Xi'an Jiaotong University since 1982. It is related with the need of repair of some national preservation relics in Xi'an. These studies include: 1) Ancient wooden structures including three national preservation relics Arrow Tower at North City Gate, City Tower at East City Gate, and Baogao Temple in Ningbao, Zhejiang province. 2) Ancient tall masonry building, the Big Goose Pagoda and Small Goose Pagoda in Xi'an. 3) Mechanical characteristics of ancient soil under foundation and city wall; the influence of caves in and under the ancient City Wall on the stability of the wall. 4) The typical Chinese ancient building at the center of city: the Bell Tower and Drum tower. 5) The behavior of Dou-Gong and Joggle joint of Chinese ancient wooden structure. 6) The mechanical behavior of ancient soils under complex stress state. A new systematical strength theory, the unified strength theory, is used to analyze the stability of ancient city wall in Xi'an and foundation of tall pagoda built in Tang dynasty. These researches also concern differential settlements of Arrow Tower and resistance to earthquake of these historical architecture heritages. Some other studies are also introduced. This paper gives a summary of these researches. Preservation and research are nowadays an essential requirement for the famous monuments, buildings, towers and others. Our society is more and more conscious of this necessity, which involves increasing activities of restoration, and then sometimes also of repair, mechanical strengthening and seismic retrofitting. Many historical buildings have in fact problems of structural strength and

  5. Invasive non-native plants have a greater effect on neighbouring natives than other non-natives.

    Kuebbing, Sara E; Nuñez, Martin A

    2016-01-01

    Human activity is creating a global footprint by changing the climate, altering habitats and reshuffling the distribution of species. The movement of species around the globe has led to the naturalization and accumulation of multiple non-native species within ecosystems, which is frequently associated with habitat disturbance and changing environmental conditions. However, interactions among species will also influence community composition, but little is known about the full range of direct and indirect interactions among native and non-native species. Here, we show through a meta-analysis of 1,215 pairwise plant interactions between 274 vascular plant species in 21 major habitat types that interactions between non-native plants are asymmetrical with interactions between non-native and native plants. Non-native plants were always bad neighbours, but the negative effect of non-natives on natives was around two times greater than the effect of non-natives on other non-natives. In contrast, the performance of non-native plants was five times higher in the presence of a neighbouring native plant species than in the presence of a neighbouring non-native plant species. Together, these results demonstrate that invaded plant communities may accumulate additional non-native species even if direct interactions between non-natives species are negative. Put another way, invasions may be more likely to lead to more invasions, requiring more active management of ecosystems by promoting native species restoration to undermine invasive positive feedback and to assist native species recovery in invaded ecosystems.

    Rosa damascena as an ornamental plant is commonly known as "Gole Mohammadi" in Iran. Iranian people have been called this plant, the flower of Prophet "Mohammad". R. damascena is traditionally used for treatment of abdominal and chest pains, strengthening the heart, menstrual bleeding, digestive problems and constipation. This paper reviews the ethnopharmacology, phytochemistry and pharmaceutical investigations on R. damascena. All relevant databases and local books on ethnopharmacology of R. damascena were probed without limitation up to 31st March 2015 and the results of these studies were collected and reviewed. R. damascena has an important position in Iranian traditional medicine. It is economically a valuable plant with therapeutic applications in modern medicine. The antimicrobial, antioxidant, analgesic, anti-inflammatory, anti-diabetic and anti-depressant properties of R. damascena have been confirmed. Citronellol and geraniol as the main components of R. damascena essential oil are responsible for pharmacological activities. Overall, R. damascena as holy ancient plant with modern pharmacological investigations should be more investigated as traditional uses in large preclinical and clinical studies. PMID:26870673

    The Neolithic is a key period in the history of the European settlement. Although archaeological and present-day genetic data suggest several hypotheses regarding the human migration patterns at this period, validation of these hypotheses with the use of ancient genetic data has been limited. In this context, we studied DNA extracted from 53 individuals buried in a necropolis used by a French local community 5,000 y ago. The relatively good DNA preservation of the samples allowed us to obtain autosomal, Y-chromosomal, and/or mtDNA data for 29 of the 53 samples studied. From these datasets, we established close parental relationships within the necropolis and determined maternal and paternal lineages as well as the absence of an allele associated with lactase persistence, probably carried by Neolithic cultures of central Europe. Our study provides an integrative view of the genetic past in southern France at the end of the Neolithic period. Furthermore, the Y-haplotype lineages characterized and the study of their current repartition in European populations confirm a greater influence of the Mediterranean than the Central European route in the peopling of southern Europe during the Neolithic transition.

    The evident connection between human evolution and climatic changes has been concurred by scientists. Although many people are trying to forecast the impacts of climatic changes on our future society, there are not any studies to quantitatively scrutinize the interrelation between climatic changes and social developments by using historical data. In line with this knowledge gap, this study adopted a scientific approach to compare the paleoclimatic records with the historical data of wars, social unrests, and dynastic transitions in China spanned from the late Tang to Qing Dynasties. Results showed that war frequency in cold phases was much higher than that in mild phases. Besides, 70%-80% of war peaks and most of the dynastic transitions and nationwide social unrests in China took place in cold phases. This phenomenon could be attributed to the diminishing thermal energy input in cold phases resulting in the fall of land-productivity and hence, the deficiency of livelihood resources across society. Accompanied with certain social circumstances, this kind of ecological stress was transformed into wars and social unrests, followed by dynastic transitions in most of the cases. By closer examination, it was even found that war frequency was negatively correlated with temperature anomaly series. As land carrying capacities vary from one climatic zone to another, the magnitude of war- temperature association also differed among different geographic regions. It is suggested that climatic change was one of the most important factors in determining the dynastic cycle and alternation of war and peace in ancient China.

    The Geoscience Alliance is a national alliance of individuals committed to broadening participation of Native Americans in the geosciences. Native Americans in this case include American Indians, Alaska Natives and people of Native Hawai'ian ancestry. Although they make up a large percentage of the resource managers in the country, they are underrepresented in degrees in the geosciences. The Geoscience Alliance (GA) members are faculty and staff from tribal colleges, universities, and research centers; native elders and community members; industry, agency, and corporate representatives; students (K12, undergraduate, and graduate); formal and informal educators; and other interested individuals. The goals of the Geoscience Alliance are to 1) create new collaborations in support of geoscience education for Native American students, 2) establish a new research agenda aimed at closing gaps in our knowledge on barriers and best practices related to Native American participation in the geosciences, 3) increase participation by Native Americans in setting the national research agenda on issues in the geosciences, and particularly those that impact Native lands, 4) provide a forum to communicate educational opportunities for Native American students in the geosciences, and 5) to understand and respect indigenous traditional knowledge. In this presentation, we look at the disparity between numbers of Native Americans involved in careers related to the geosciences and those who are receiving bachelors or graduate degrees in the geosciences. We address barriers towards degree completion in the geosciences, and look at innovative programs that are addressing those barriers.

  11. Ancient iron and lead isotope analysis

    International Nuclear Information System (INIS)

    Full text: Little work has been published to date on the subject of lead isotope analysis of ancient iron artefacts. That which has suffers from a lack of understanding of the nature of ancient iron, and of the behavior of lead in relation to iron oxides. This paper examines data from a lead isotope study of 12th-10th Century B.C.E. iron artefacts from Israel and Palestine, and iron ores from these and surrounding areas, focusing on the issues of iron corrosion and lead contamination. The data shows that experimentally produced bloomery iron contains very little lead (less than O. 1 ppm), with most lead in the ore being reduced in the smelting process and lost to the slag. This low quantity of lead raises the question of contamination in samples which have been corroding whilst buried, in this case, for 3000 years. It is proposed that useful lead isotope data may be obtained where analysis of hydrated iron oxides in particular is avoided, as they commonly make up the outer layers of recovered ancient iron objects, formed in direct association with surrounding soil and rock. Lead contamination of these porous oxides- is a constantly observed feature of the material, and the affinity of lead for such oxides is well documented. Where there exists uncorroded iron (a rare event), or where there exists a core of magnetite beneath the outer hydrated oxide layers, it may be possible to obtain useful lead isotope data, which reflect the isotopic composition of the metal as it emerged from the furnace in antiquity. A magnetic separation process and washing in cold 7M HCl are proposed as means of removing contaminated hydrated iron oxides from this more useful material in the laboratory, prior to lead isotope analysis

    Full Text Available Summary: Ancient schwannoma, is a rare variant of schwannoma with characterization of degenerative changes and diffuse hypercellularity. Retroperitoneal presacral form is often found incidentally, because they present with vague symptoms or symptomless. Schwannoma occurring in this area occasionally presents with enormous dimensions, known as a giant schwannoma. The tumor removal is a surgical challenge due to the difficult approach and abundant vascularity. In this report we describe a 61 –year old female presented to ER with vaginal bleeding and lower abdominal pain. The case diagnosed on clinical, CT and MRI findings to be a fibroma of the left ovary. Exploration by the gynecology team revealed a huge retroperitoneal presacral tumor compressing the left external iliac vessels and displacing the left ureter; they took a biopsy and closed the abdomen. Histopathological result was benign schwannoma. The patient were referred to our hospital (Al Hada Armed Forces Hospital, Taif, Saudi Arabia to be managed from postoperative DVT when her family asked our department of surgery for further management and signed a high risk consent. We explored the case after insertion of IVC filter and ureteric catheter. A 20x20 cm mass was thoroughly dissected and resected with part of sacrum. The final histopathological result was benign nerve sheath tumor with features consistent with degenerated (ancient schwannoma and the tumor was completely resected. The patient was discharged from the hospital without complications and follow up for three years revealed no recurrence. The clinical, radiological, and pathological features of this disease are discussed in this report. To conclude, retroperitoneal giant ancient schwannomas are a rare variant of the benign schwannoma and often present as unrecognized slow growing masses.

    Full Text Available Abstract Background The timing of the origin of introns is of crucial importance for an understanding of early genome architecture. The Exon theory of genes proposed a role for introns in the formation of multi-exon proteins by exon shuffling and predicts the presence of conserved splice sites in ancient genes. In this study, large-scale analysis of potential conserved splice sites was performed using an intron-exon database (ExInt derived from GenBank. Results A set of conserved intron positions was found by matching identical splice sites sequences from distantly-related eukaryotic kingdoms. Most amino acid sequences with conserved introns were homologous to consensus sequences of functional domains from conserved proteins including kinases, phosphatases, small GTPases, transporters and matrix proteins. These included ancient proteins that originated before the eukaryote-prokaryote split, for instance the catalytic domain of protein phosphatase 2A where a total of eleven conserved introns were found. Using an experimental setup in which the relation between a splice site and the ancientness of its surrounding sequence could be studied, it was found that the presence of an intron was positively correlated to the ancientness of its surrounding sequence. Intron phase conservation was linked to the conservation of the gene sequence and not to the splice site sequence itself. However, no apparent differences in phase distribution were found between introns in conserved versus non-conserved sequences. Conclusion The data confirm an origin of introns deep in the eukaryotic branch and is in concordance with the presence of introns in the first functional protein modules in an 'Exon theory of genes' scenario. A model is proposed in which shuffling of primordial short exonic sequences led to the formation of the first functional protein modules, in line with hypotheses that see the formation of introns integral to the origins of genome evolution

  14. On Borders: From Ancient to Postmodern Times

    The article deals with the evolution of the concept of borders between human groups and with its slow evolution from the initial no men's land zones to the ideal single-dimension linear borders. In ancient times the first borders were natural, such as mountain ranges or large rivers until, with the development of Geodesy, astronomical borders based on meridians and parallels became a favourite natural base. Actually, Modern States adopted these to fix limits in unknown conquered territories. The postmodern thought led give more importance to cultural borders until, in the most recent times, is becoming rather impossible to fix borders in the virtual cyberspace.

    Halite is one of the most extreme environments to support life. From the drought of the Atacama Desert to salt deposits up to Permian in age and 2000 meters in burial depth, live microbes have been found. Because halite is geologically stable and impermeable to ground water, the microbes allegedly have a syndepositional origin, making them the oldest organisms known to live on Earth. Recently, our understanding of the microbial diversity inside halite has broadened, and the first genome sequences of ancient halite-buried microbes are now available. The secrets behind prolonged survival in salt are also starting to be revealed. PMID:26796472

    The Peten, once inhabited by a population of several million before the collapse of the ancient Maya in the 10th and 11th centuries, is being repopulated toward its former demographic peak. Environmental dynamics, however, impose severe constraints to further development. Current practices in subsistence, commercial agriculture, and cattle raising are causing rapid deforestation resulting in the destruction of environmental and archeological resources. The use of remote sensing and Geographic Information Systems (GIS) technology is a cost-effective methodology for addressing issues in Maya archeology as well as monitoring the environmental impacts being experienced by the current population.

    In pre-agricultural era, entire mankind consumed meat as early man was a hunter. Possibly he ate from plants sources which grew in the wilderness. With the advent of agriculture as an outcome of civilization, man acquired the ability to cultivate what he wanted, as by now he was influenced to some extent by the selection of the food that he wanted to eat. All this ultimately led to him taking to vegeterianism, which probably did not occur until approximately 1500 B.C. It is tried in this study to examine the concept of nutrition, balanced diet, appetite, food etiquette, food sanitation and food poisoning etc. in ancient India. PMID:11618846

  2. Study of ancient pottery from Slovakia

    International Nuclear Information System (INIS)

    Ancient pottery samples collected from south-west Slovakia were studied through subjective observation and by Moessbauer spectroscopy. This method is convenient for determining the provenance and the manufacture of pottery. Transformations, induced by firing the clay and characterized by Moessbauer spectroscopy, give valuable information regarding the manufacture as, for instance, the final temperature of firing in it. The relative abundance of Fe2+ and Fe3+ determines the atmosphere used to fire a pottery. It has been found that the determination of the firing atmosphere obtained through the subjective observation is in good agreement with that obtained using Moessbauer spectroscopy. An unfired and fired clay was also investigated. (orig.)

    The earliest Chinese ancient glasses before the West Han Dynasty (200 BC) from different regions are studied. The glass samples were unearthed from Hunan, Hubei, Yunnan, Sichuan, Guizhou, Guangdong and Xinjiang of China. The chemical composition of these glasses samples is analyzed by proton induced X-ray emission (PIXE) technique, energy dispersive X-ray fluorescence (EDXRF) method and inductively coupled plasma atomic emission spectrometry (ICP-AES). It is shown that the glass chemical compositions belong to barium-lead silicate BaO-PbO-SiO2, potash soda lime silicate K2O (Na2O)-CaO-SiO2 (K2O/Na2O>1), soda potash lime silicate Na2O (K2O)-CaO-SiO2 (K2O/Na2O<1) and potash silicate K2O-SiO2 glass systems, respectively. The origins of the earliest Chinese ancient glasses are discussed from the archaeological and historical points of view. These four types of Chinese ancient glasses were all made in Chinese territory using local raw materials. The glass preparation technology was related to the Chinese ancient bronze metallurgy and proto-porcelain glaze technology. The glass technology relationship between the East and the West is analyzed at the same time.

    Full Text Available We examined genetic diversity and population structure in the American landmass using 678 autosomal microsatellite markers genotyped in 422 individuals representing 24 Native American populations sampled from North, Central, and South America. These data were analyzed jointly with similar data available in 54 other indigenous populations worldwide, including an additional five Native American groups. The Native American populations have lower genetic diversity and greater differentiation than populations from other continental regions. We observe gradients both of decreasing genetic diversity as a function of geographic distance from the Bering Strait and of decreasing genetic similarity to Siberians--signals of the southward dispersal of human populations from the northwestern tip of the Americas. We also observe evidence of: (1 a higher level of diversity and lower level of population structure in western South America compared to eastern South America, (2 a relative lack of differentiation between Mesoamerican and Andean populations, (3 a scenario in which coastal routes were easier for migrating peoples to traverse in comparison with inland routes, and (4 a partial agreement on a local scale between genetic similarity and the linguistic classification of populations. These findings offer new insights into the process of population dispersal and differentiation during the peopling of the Americas.

  6. Spectroscopic studies on native proteins, glycated and inhibited nonenzymatically

    International Nuclear Information System (INIS)

    The nonenzymatic glucation is an irreversible process whose speed depends on the concentration reducer sugar in plasma. The glycated albumins is higher in diabetic people. Up to now, this has been indicated as an important mechanism in the pathology of the the secondary complications associated with diabetes and the normal aging. Recently a lot of interest has been focused on the search of certain compounds (inhibitors) to prevent the glucation and / or the formation of ending products of advanced glucation, AGE. The reaction of glucose with the human albumin and γ globulins and the effects of acid acetylsalicylic and ascorbic acid were studied. The proteins were incubated with glucose in absence and in presence of inhibitors for one month. The solutions were dialysed and then lyophilizated. The absorption spectra were taken for native proteins, glycated and inhibited (2 mg/ml) in phosphate 10 mM buffer, p H 7.3. It is observed that the spectra of the acetylate proteins and native proteins are practically same. This can be interpreted as an inhibitor effect of acid acetylsalicylic on glucation. In all the observed cases the glycated proteins absorb more than the native ones and they present a line toward the visible region. The ascorbic acid absorbs below the native proteins and it doesn't present the same characteristics. The increase and / or the decrease in the absorption picks can be associated with environmental changes affecting the groups involved in the absorption process

  11. Greek Death-Cult, Modern and Ancient: A Comparison of a Mediterranean and Balkan Cultural Pattern

    Directory of Open Access Journals (Sweden)

    E.J. Håland

    2010-08-01

    Full Text Available The article examines emotion and identity in connection with Greek death-cult in an attempt to clarify certain contemporary political phenomena in the Mediterranean and Balkan area. The cult of the dead is a common cultural pattern in the area. Why is this cult so persistent? What is death-cult and how does it manifest itself? The article delves into its lasting importance in the Greek part of the cultural area, where the author has conducted several fieldworks. To illustrate the persistence of this cultural pattern, the characteristic aspects connected with death-cult in Greek tradition are discussed: The comparison is based on festivals, which are dedicated to deceased persons and domestic death-rituals combined with ancient sources. Based on them an analytical survey of the relationship between the death-cult dedicated to deceased mediators in ancient and modern society, as it is manifested through laments, burials and the following memorial rituals is made. The modern domestic rituals people perform for their own dead influence the official ideological rituals, and vice versa, the domestic rituals reflect public performances. A study of modern cult practices reveals many parallels with the official cult of the ancients, and suggests ways in which modern rituals can throw new light upon the ancient rituals and vice versa. The article seeks to demonstrate how new ideologies must adjust to older rituals and beliefs and how public and domestic rituals are connected. The article finally suggests how these similarities might represent a common way of expression within a larger context in which the Mediterranean and Balkan cultural meaning of emotion is central.

  12. Sample Return from Ancient Hydrothermal Springs

    Allen, Carlton C.; Oehler, Dorothy Z.

    2008-01-01

    Hydrothermal spring deposits on Mars would make excellent candidates for sample return. Molecular phylogeny suggests that that life on Earth may have arisen in hydrothermal settings [1-3], and on Mars, such settings not only would have supplied energy-rich waters in which martian life may have evolved [4-7] but also would have provided warm, liquid water to martian life forms as the climate became colder and drier [8]. Since silica, sulfates, and clays associated with hydrothermal settings are known to preserve geochemical and morphological remains of ancient terrestrial life [9-11], such settings on Mars might similarly preserve evidence of martian life. Finally, because formation of hydrothermal springs includes surface and subsurface processes, martian spring deposits would offer the potential to assess astrobiological potential and hydrological history in a variety of settings, including surface mineralized terraces, associated stream deposits, and subsurface environments where organic remains may have been well protected from oxidation. Previous attempts to identify martian spring deposits from orbit have been general or limited by resolution of available data [12-14]. However, new satellite imagery from HiRISE has a resolution of 28 cm/pixel, and based on these new data, we have interpreted several features in Vernal Crater, Arabia Terra as ancient hydrothermal springs [15, 16].

    Humankind has always sought to recognize the nature of various sky related phenomena and tried to give them explanations. The purpose of this study is to identify ancient Armenians' pantheistic and cosmological perceptions, world view, notions and beliefs related to the Earth. The paper focuses on the structure of the Earth and many other phenomena of nature that have always been on a major influence on ancient Armenians thinking. In this paper we have compared the term Earth in 31 languages. By discussing and comparing Universe structure in various regional traditions, myths, folk songs and phraseological units we very often came across to "Seven Heavens" (Seven heavens is a part of religious cosmology found in many major religions such as Islam, Judaism, Hinduism and Christianity (namely Catholicism) and "Seven Earths". Armenians in their turn divided Earth and Heavens into seven layers. And in science too, both the Earth and the Heavens have 7 layers. The Seven Heavens refer to the layers of our atmosphere. The Seven Earths refer to the layers of the Earth (from core to crust), as well as seven continents. We conclude that the perception of celestial objects varies from culture to culture and preastronomy had a significant impact on humankind, particularly on cultural diversities.

    The Greek and Roman theatres are among the most precious and spectacular items of cultural heritage in the Mediterranean countries. The theatres are famous not only for their impressive architecture, but also for the acoustic qualities. For this reason it is important to consider these theatres as an acoustical heritage and to study their sound field. Within the activities of the ERATO (identification Evaluation and Revival of the Acoustical heritage of ancient Theatres and Odea) project, acoustical measurements were taken in well-preserved ancient Roman theatres at Aspendos (Turkey) and Jerash (Jordan). Roman theatres have an impressive stage building that forms a back wall in the orchestra area, and it was found that, from the analysis of the acoustical parameters, the reverberation time (e.g., 1.7 s at middle frequencies in the theatre of Aspendos) is quite long compared not only with other open-space theatres but also with closed spaces. Contrary to modern halls the clarity is high and this fact, together with a low sound level in most of the seats, gives the sound field a unique character.

    Full Text Available This qualitative study investigates discourse-level patterns typically employed by a Turkish lecturer based on the syntactic patterns found in the collected data. More specifically, the study aims to reveal how different native and non-native speakers of English perceive discourse patterns used by a non-native lecturer teaching in English. The data gathered from a Turkish lecturer teaching finance, and the interviews both with the lecturer and the students. The lecturer and the students were videotaped and the data was evaluated by content analysis. The results revealed a difference between the way non-native and native speakers evaluate an oral discourse of a non-native lecturer teaching in English. Native speakers of English found the oral performance moderately comprehensible, while non-native speakers found it relatively comprehensible.

    International Nuclear Information System (INIS)

    Determination of the geological provenance of gold is a powerful argument in the authentication of ancient gold artifacts. Small samples (hundreds of microns) of native gold from Transylvanian deposits were scanned by micro-PIXE to obtain information on the natural Au–Ag alloy composition and on the presence of trace elements such as Sn, Sb, and Cu. The experiments were performed at the AGLAE Louvre and LNL AN2000 accelerators. Mineral identification was confirmed by a micro-mineralogical study using the INFLPR-Magurele Scanning Electron Microscope associated with an Energy-dispersive X-ray spectroscopy (EDAX) facility.

    2006-11-01

    Enterobius vermicularis, pinworm, is one of the most common helminths worldwide, infecting nearly a billion people at all socio-economic levels. In prehistoric populations the paleoparasitological findings show a pinworm homogeneous distribution among hunter-gatherers in North America, intensified with the advent of agriculture. This same increase also occurred in the transition from nomad hunter-gatherers to sedentary farmers in South America, although E. vermicularis infection encompasses only the ancient Andean peoples, with no record among the pre-Colombian populations in the South American lowlands. However, the outline of pinworm paleoepidemiology has been supported by microscopic finding of eggs recovered from coprolites. Since molecular techniques are precise and sensitive in detecting pathogen ancient DNA (aDNA), and also could provide insights into the parasite evolutionary history, in this work we have performed a molecular paleoparasitological study of E. vermicularis. aDNA was recovered and pinworm 5S rRNA spacer sequences were determined from pre-Columbian coprolites (4110 BC-AD 900) from four different North and South American archaeological sites. The sequence analysis confirmed E. vermicularis identity and revealed a similarity among ancient and modern sequences. Moreover, polymorphisms were identified at the relative positions 160, 173 and 180, in independent coprolite samples from Tulán, San Pedro de Atacama, Chile (1080-950 BC). We also verified the presence of peculiarities (Splicing leader (SL1) RNA sequence, spliced donor site, the Sm antigen biding site, and RNA secondary structure) which characterise the SL1 RNA gene. The analysis shows that the SL1 RNA gene of contemporary pinworms was present in pre-Columbian E. vermicularis by 6110 years ago. We were successful in detecting E. vermicularis aDNA even in coprolites without direct microscopic evidence of the eggs, improving the diagnosis of helminth infections in the past and further

    Full Text Available The anti-Chinese protests that were organized throughout European cities fol­lowing the route of the Olympic torch from Athens to Beijing, and the conflicts that erupted with strong emotions on both sides between the protestors and the Chinese citizens, will without a doubt remain a lasting memory of the 2008 Olympic games. Regardless of these protests' justified motives, there is a visible paradoxical role-switch in the scenes that circled the globe for months: the Olympic torch and Olympic idea, were being defended by China as a highest value and the source of their own past and identity, and attacked by the people (Europeans on whose land that very idea had been created and nurtured for over a hundred years. How should these contradictory images be understood? How did it come to this that the Chinese view themselves as the keepers of the Olympic tradition, that the pride of the Chinese nation, focused in that flame, gets hurt in attempts of European protestors to put it out? The modern Olympic Games, founded in 1896, were one of the echoes of a centuries' long Western European fascination with the Antique. This phenomenon of the Antique admiration has brought about a redefining of the European civilization's past, the abandoning the biblical narrative and the gradual creation of a secular story that we call modern history, in which Greece and Rome have become the main references of origin. The same process influenced the formation of national states that perceive, apart from their own histories, a collective cultural origin in Ancient Greece. Of course, the Galls, Francs or Germans had little in common with ancient Greeks; but modern European nations unite this fictional image of the Antique with the firm belief that it is the source of their cultural identity. For instance, not only did the 18th century French and English believe that they originated from ancient Greece but they managed to successfully 'sell' that story to modern Greeks

  9. The Collapse of Ancient Societies by Great Earthquakes

    Science.gov (United States)

    Nur, A. M.

    2001-12-01

    Although earthquakes have often been associated with inexplicable past societal disasters their impact has thought to be only secondary for two reasons: Inconclusive archaeological interpretation of excavated destruction, and misconceptions about patterns of seismicity. However, new and revised archaeological evidence and a better understanding of the irregularities of the time-space patterns of large earthquakes together suggest that earthquakes (and associated tsunamis) have probably been responsible for some of the great and enigmatic catastrophes in ancient times. The most relevant aspect of seismicity is the episodic time-space clustering of earthquakes such as during the eastern Mediterranean seismic crisis in the second half of the 4th century AD and the seismicity of the north Anatolian fault during our century. During these earthquake clusters, plate boundary rupture by a series of large earthquakes that occur over a period of only 50 to 100 years or so, followed by hundreds or even thousands of years of relative inactivity. The extent of the destruction by such rare but powerful earthquake clusters must have been far greater than similar modern events due to poorer construction and the lack of any earthquake preparedness in ancient times. The destruction by very big earthquakes also made ancient societies so vulnerable because so much of the wealth and power was concentrated and protected by so few. Thus the breaching by an earthquake of the elite's fortified cities must have often led to attacks by (1) external enemies during ongoing wars (e.g., Joshua and Jericho, Arab attack on Herod's Jerusalem in 31 BCE); (2) neighbors during ongoing conflicts (e.g., Mycenea's fall in @1200 BCE, Saul's battle at Michmash @1020 BCE); and (3) uprisings of poor and often enslaved indigenous populations (e.g., Sparta and the Helots @465 BCE, Hattusas @1200 BCE?, Teotihuacan @ 700 AD). When the devastation was by a local earthquake, during a modest conflict, damage was

Statues and paintings of the ancient roman period tell us of this astonishing world of fighters. There are traces of famous gladiators all over the known world at Roman times, resembling our Mohammad Ali or Mike Tyson. Most of them grew up in fighting schools, the most famous in Capua, near Naples in Italy: Spartacus, the rebel gladiator who inflicted a severe defeat to Roman army, came from there. Gladiators had to endure long session of training to fight in the arena. Considering the modern diets of strength athletes, we should expect that gladiators had a high protein diet. However, analysis of their bones has put forward the hypothesis that gladiators were vegetarian athletes: in his accounts of Rome, the ancient historian Plinius refers to gladiators as "hordearii" (barley-eaters (Eichholz et al., 1938. Plants contain higher levels of strontium than animal tissues. People who consume more plants and less meat will build up measurably higher levels of strontium in their bones. Levels of strontium in the gladiators' bones were two times as high than the bones of contemporary Ephesians (Kanz and Grossschmidt, 2007. Roman army troopers, the "legionnaires", had daily expenditure of energy that can be estimated at around 5000 kcal for the legionnaire performing engineer work and at 6000 kcal for the legionnaire in war action. At present, only workmen and sportsmen reach such levels of energy expenditure (Fornaris and Aubert, 1998. Legionnaires were able to endure long war campaignes and endless "magnis itineribus" (forced marches with incredible resistance to fatigue. The legionnaire's daily ration consisted of 78% carbohydrates, mainly from wheat or barley. This diet has the

  11. Mitochondrial DNA analysis of ancient Sampula population in Xinjiang

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The archaeological site of Sampula cemetery was located about 14 km to the southwest of the Luo County in Xinjiang Khotan, China, belonging to the ancient Yutian kingdom. 14C analysis showed that this cemetery was used from 217 B.C. to 283 A.D.Ancient DNA was analyzed by 364 bp of the mitochondrial DNA hypervariable region Ⅰ (mtDNA HVR-Ⅰ), and by six restriction fragment length polymorphism (RFLP) sites of mtDNA coding region. We successfully extracted and sequenced intact stretches of maternally inherited mtDNA from 13 out of 16 ancient Sampula samples. The analysis of mtDNA haplogroup distribution showed that the ancient Sampula was a complex population with both European and Asian characteristics. Median joining network of U3 sub-haplogroup and multi-dimensional scaling analysis all showed that the ancient Sampula had maternal relationship with Ossetian and Iranian.

  12. Exploring Ancient Skies An Encyclopedic Survey of Archaeoastronomy

    Kelley, David H

    2005-01-01

    Exploring Ancient Skies brings together the methods of archaeology and the insights of modern astronomy to explore the science of astronomy as it was practiced in various cultures prior to the invention of the telescope. The book reviews an enormous and growing body of literature on the cultures of the ancient Mediterranean, the Far East, and the New World (particularly Mesoamerica), putting the ancient astronomical materials into their archaeological and cultural contexts. The authors begin with an overview of the field and proceed to essential aspects of naked-eye astronomy, followed by an examination of specific cultures. The book concludes by taking into account the purposes of ancient astronomy: astrology, navigation, calendar regulation, and (not least) the understanding of our place and role in the universe. Skies are recreated to display critical events as they would have appeared to ancient observers - events such as the supernova of 1054, the 'lion horoscope' or the 'Star of Bethlehem.'

    Full Text Available No século XIX, a construção do Estado nacional foi levada adiante pela eficácia da persuasão ou pela força da guerra. A expansão agro-pastoril, em territórios ainda não conquistados aos índios, fez parte dessa construção. Novas áreas foram ocupadas, novos territórios incorporados, e o Estado nacional trabalhou no sentido de demarcar essas novas fronteiras, fazendo-se presente nesses territórios. A ocupação de territórios indígenas, a modernização e as idéias de europeização foram praticas que marcaram a sociedade nacional no século XIX. Dessa forma, as populações indígenas tornavam-se um obstáculo para a consolidação desse Estado em expansão. Muitas foram as formulações sobre como resolver a questão e várias delas foram gestadas no Instituto Histórico e Geográfico Brasileiro e veiculadas pela Revista do IHGB, desde a sua fundação. Entendemos que muitas dessas formas de pensamento imprimiam a direção a ser seguida na elaboração das políticas indigenistas do Império e das províncias, e que a RIHGB foi um importante meio de divulgação dessas idéias por todo o Brasil. Assim, propomo-nos a verificar o rol de sugestões que os freqüentadores das reuniões do IHGB elaboraram e discutiram como sendo a solução para a “questão indígena”, nessa segunda metade do século XIX, que foram impressas nas paginas da Revista do IHGB, da sua fundação até 1889.In the nineteenth century, the national state was built both through persuasion and war. The agro-pastoral expansion into territories not yet taken from the Indians is part of this construction, when new areas and territories were occupied and incorporated into the agricultural frontier and the national state marked these new frontiers by its institutional presence. The nineteenth-century Brazilian society was marked by native people’s territory occupation by the agricultural frontier, by modernization and Europe-oriented ideas. Thus the native

    The Peten region of northern Guatemala is one of the last places on earth where major archeological sites remain to be discovered. It was in this region that the Maya civilization began, flourished, and abruptly disappeared. Remote sensing technology is helping to locate and map ancient Maya sites that are threatened today by accelerating deforestation and looting. Thematic Mapper and IKONOS satellite and airborne Star3-I radar data, combined with Global Positioning System (GPS) technology, are successfully detecting ancient Maya features such as cities, roadways, canals, and water reservoirs. Satellite imagery is also being used to map the bajos, which are seasonally flooded swamps that cover over 40% of the land surface. The use of bajos for farming has been a source of debate within the professional community for many years. But the recent detection and verification of cultural features within the bajo system by our research team are providing conclusive evidence that the ancient Maya had adapted well to wetland environments from the earliest times and utilized them until the time of the Maya collapse. The use of the bajos for farming is also an important resource for the future of the current inhabitants who are experiencing rapid population growth. Remote sensing imagery is also demonstrating that in the Preclassic period (600 BC- AD 250), the Maya had already achieved a high organizational level as evidenced by the construction of massive temples and an elaborate inter-connecting roadway system. Although they experienced several setbacks such as droughts and hurricanes, the Maya nevertheless managed the delicate forest ecosystem successfully for several centuries. However, around AD 800, something happened to the Maya to cause their rapid decline and eventual disappearance from the region. The evidence indicates that at this time there was increased climatic dryness, extensive deforestation, overpopulation, and widespread warfare. This raises a question that

  15. Cosmologies of the ancient Mediterranean world

    Directory of Open Access Journals (Sweden)

    John T. Fitzgerald

    2013-06-01

    Full Text Available Cosmology is concerned with the order of the universe and seeks to provide an account, not only of that order, but also of the mind or reason behind it. In antiquity, the cosmos was usually understood religiously, such that the cosmologies of the ancient Mediterranean world were either religious in nature or constituted a reaction to a religiously conceived understanding of the structures of the universe. The oldest form in which ancient cosmologies occur is myth, which, owing to its elasticity as a form, enabled them to be appropriated, adapted and used by different groups. In addition, different cosmologies co-existed within the same ancient culture, each having an authoritative status. This article provides an introductory overview of these cosmological myths and argues that a comparative approach is the most fruitful way to study them. Emphasis is given to certain prominent cosmological topics, including theogony (the genesis of the divine or the relationship of the divine to the cosmos, cosmogony (the genesis of the cosmos, and anthropogony (the origin of humans within the cosmos. Although these myths vary greatly in terms of content and how they envision the origin of the cosmos, many of them depict death as part of the structure of the universe.Kosmologie het te doen met die orde van die heelal en wil rekenskap gee van hierdie orde en ook van die bewussyn daaragter. In die antieke tyd is die kosmos gewoonlik godsdienstig verstaan, met die gevolg dat die kosmologieë van die antieke Mediterreense wêreld óf ’n godsdienstige aard gehad het óf bestaan het uit ’n reaksie op ’n godsdienstig-geskepte begrip van die strukture van die heelal. Mites was die oudste vorm waarin antieke kosmologieë voorkom wat vanweë hulle plooibaarheid dit bewerk het dat hierdie kosmologieë deur verskillende groepe toegeëien, aangepas en gebruik kon word. Hierbenewens het verskillende kosmologieë in die antieke kultuur langs mekaar bestaan – elkeen

    China's linguistic and geographic diversity leads many Chinese individuals to identify themselves and others not simply as Chinese, but rather by their native place and provincial origin. Negative personality traits are often attributed to people from specific areas. People from Henan, in particular, appear to be singled out as possessing a host of negative traits. Such prejudice does not necessarily lead to wage discrimination. Whether or not it does depends on the nature of the local labor ...

    2003-02-12

    The original presettlement forests of North America have been dramatically altered, but thousands of unmolested ancient forests survive on remote or noncommercial terrain, including dry-site eastern hardwoods such as chestnut oak and post oak, the pinyon-juniper woodlands of the semiarid West, oak woodlands of California and in northeast Mexico, and the boreal forests of Canada and Alaska. Long tree-ring chronologies derived from these ancient forest remnants provide irreplaceable archives of environmental variability which are crucial for evaluating present and future change. Temperature sensitive tree -ring chronologies from cold treeline environments place 20th century warming into long historical perspective, and moisture sensitive tree-ring chronologies provide analogs to the decadal moisture regimes of the 20th century. These tree-ring data suggests that the 16th century megadrought was the most severe-sustained drought to impact North America in 1500 years, and had huge environmental and social impacts at the dawn of European settlement.

  5. People of the ancient rainforest: late Pleistocene foragers at the Batadomba-lena rockshelter, Sri Lanka.

    Batadomba-lena, a rockshelter in the rainforest of southwestern Sri Lanka, has yielded some of the earliest evidence of Homo sapiens in South Asia. H. sapiens foragers were present at Batadomba-lena from ca. 36,000 cal BP to the terminal Pleistocene and Holocene. Human occupation was sporadic before the global Last Glacial Maximum (LGM). Batadomba-lena's Late Pleistocene inhabitants foraged for a broad spectrum of plant and mainly arboreal animal resources (monkeys, squirrels and abundant rainforest snails), derived from a landscape that retained equatorial rainforest cover through periods of pronounced regional aridity during the LGM. Juxtaposed hearths, palaeofloors with habitation debris, postholes, excavated pits, and animal and plant remains, including abundant Canarium nutshells, reflect intensive habitation of the rockshelter in times of monsoon intensification and biome reorganisation after ca. 16,000 cal BP. This period corresponds with further broadening of the economic spectrum, evidenced though increased contribution of squirrels, freshwater snails and Canarium nuts in the diet of the rockshelter occupants. Microliths are more abundant and morphologically diverse in the earliest, pre-LGM layer and decline markedly during intensified rockshelter use on the wane of the LGM. We propose that changing toolkits and subsistence base reflect changing foraging practices, from shorter-lived visits of highly mobile foraging bands in the period before the LGM, to intensified use of Batadomba-lena and intense foraging for diverse resources around the site during and, especially, following the LGM. Traces of ochre, marine shell beads and other objects from an 80 km-distant shore, and, possibly burials reflect symbolic practices from the outset of human presence at the rockshelter. Evidence for differentiated use of space (individual hearths, possible habitation structures) is present in LGM and terminal Pleistocene layers. The record of Batadomba-lena demonstrates that Late Pleistocene pathways to (aspects of) behavioural 'modernity' (composite tools, practice of symbolism and ritual, broad spectrum economy) were diverse and ecologically contingent.

  7. Ecological impacts of non-native species

    Wilkinson, John W.

    2012-01-01

    Non-native species are considered one of the greatest threats to freshwater biodiversity worldwide (Drake et al. 1989; Allen and Flecker 1993; Dudgeon et al. 2005). Some of the first hypotheses proposed to explain global patterns of amphibian declines included the effects of non-native species (Barinaga 1990; Blaustein and Wake 1990; Wake and Morowitz 1991). Evidence for the impact of non-native species on amphibians stems (1) from correlative research that relates the distribution or abundance of a species to that of a putative non-native species, and (2) from experimental tests of the effects of a non-native species on survival, growth, development or behaviour of a target species (Kats and Ferrer 2003). Over the past two decades, research on the effects of non-native species on amphibians has mostly focused on introduced aquatic predators, particularly fish. Recent research has shifted to more complex ecological relationships such as influences of sub-lethal stressors (e.g. contaminants) on the effects of non-native species (Linder et al. 2003; Sih et al. 2004), non-native species as vectors of disease (Daszak et al. 2004; Garner et al. 2006), hybridization between non-natives and native congeners (Riley et al. 2003; Storfer et al. 2004), and the alteration of food-webs by non-native species (Nystrom et al. 2001). Other research has examined the interaction of non-native species in terms of facilitation (i.e. one non-native enabling another to become established or spread) or the synergistic effects of multiple non-native species on native amphibians, the so-called invasional meltdown hypothesis (Simerloff and Von Holle 1999). Although there is evidence that some non-native species may interact (Ricciardi 2001), there has yet to be convincing evidence that such interactions have led to an accelerated increase in the number of non-native species and cumulative impacts are still uncertain (Simberloff 2006). Applied research on the control, eradication, and

  9. Ancient asteroids enriched in refractory inclusions.

    Sunshine, J M; Connolly, H C; McCoy, T J; Bus, S J; La Croix, L M

    2008-04-25

    Calcium- and aluminum-rich inclusions (CAIs) occur in all classes of chondritic meteorites and contain refractory minerals predicted to be the first condensates from the solar nebula. Near-infrared spectra of CAIs have strong 2-micrometer absorptions, attributed to iron oxide-bearing aluminous spinel. Similar absorptions are present in the telescopic spectra of several asteroids; modeling indicates that these contain approximately 30 +/- 10% CAIs (two to three times that of any meteorite). Survival of these undifferentiated, large (50- to 100-kilometer diameter) CAI-rich bodies suggests that they may have formed before the injection of radiogenic 26Al into the solar system. They have also experienced only modest post-accretionary alteration. Thus, these asteroids have higher concentrations of CAI material, appear less altered, and are more ancient than any known sample in our meteorite collection, making them prime candidates for sample return.

    Here we analyze the hydraulic performance of an ancient Spanish horizontal watermill. Previous studies of similar devices have focused on qualitative descriptions of their technical functioning, providing efficiency curves based on two-dimensional analytical approximations. In contrast, here we perform three-dimensional computational fluid dynamics (CFD) simulations that allow us to obtain quantitative values for both the hydraulic torque and the power. The results here found reveal how previous studies clearly overestimated the efficiency of these devices. Finally, we make use of the capabilities of CFDs by investigating the performance of a modified blade profile. The new design here proposed successfully increases the energy efficiency (up to 44%) in comparison with the classical one. (author)

    International Nuclear Information System (INIS)

    In the last period of Tong Dynasty, Jingdezhen began its production of ceramics. During the Song Dynasty, the ceramic industry greatly developed and produced fine white ware at Hutian. In the Yuan Dynastry, Hutian became the centre of production making the world famous blue and white wares. Here are reported results of analyses of ancient porcelians of Hutian in Jiangdezhen by reactor neutron activation analysis. The results show that the patterns of eight rare earth elements are apparently different for products in different periods, indicating that methods for producing ceramics or kinds of clay used were different. The contents of some other trace elements such as hafnium, tantalum, thorium and uranium show the same regularity in difference of composition also

    Singh, Satendra; Khetarpal, Abha

    2012-04-01

    The Rime of the Ancient Mariner was written by Coleridge and is a classic poetry about retribution, punishment, guilt, and curse. Religious beliefs and delusions can arise from neurologic lesions and anomalous experiences, suggesting that at least some religious beliefs can be pathological. Looking at the poem through the psychiatric and psychological domain, the symbolism, the narration and the entire setting of the poem represents Post Traumatic Stress Disorder. Mariner's reactions are beautifully portrayed from the psychoanalytic point of view and the literary piece shows claustrophobia, stygiophobia, dikephobia, and poinephobia. The mental stress of a person under a crisis situation has remarkably been evoked in this poem. This incredible piece of art expresses how the realization of divine love within oneself has the power to heal pain and suffer. PMID:23162202

    Liu, Jia; Wang, Lu-Ning; Tian, Jin-Zhou

    2012-12-01

    A search of previous records in the literatures was done to summarize the opinions for dementia in ancient China. The earliest description of dementia was traced in the Yellow emperor's internal classic, a book written 2000 years ago. Hua Tuo (AD 140-208) in Han Dynasty first denominated "dementia" in the book, Hua Tuo Shen Yi Mi Zhuan. The pathogenesis of dementia could be generalized as the insufficiency of Qi, a flowing energy; the stagnation of phlegm, a harmful liquid substance in the body; and the blood stasis, which were also regarded as therapeutic targets. Therefore, we can conclude that dementia has been recognized and investigated in traditional Chinese medicine, which is definitely before the industrial civilization era. PMID:22835605

    Discoveries of some ancient medical instruments and equipment found in the Hellenic world have been published in magazines of general interest and in a rare Greek medical journal, yet none caught the attention of ophthalmologists. Among these instruments are two forms of the famous 'Kenteterion', dating from the Hellenistic period, used for the couching of cataract. These were found on the island of Milos in the last century. Two magnifying lenses of the Archaic period from the recent Cretan excavations gave us the opportunity to discuss the problem of their medical use. The two drop-bottles from the excavations on Cyprus and at Tanagra, which are also described, seem to be of medical, and possible ophthalmological, use. PMID:9657298

    Polyomaviruses are a family of DNA tumor viruses that are known to infect mammals and birds. To investigate the deeper evolutionary history of the family, we used a combination of viral metagenomics, bioinformatics, and structural modeling approaches to identify and characterize polyomavirus sequences associated with fish and arthropods. Analyses drawing upon the divergent new sequences indicate that polyomaviruses have been gradually co-evolving with their animal hosts for at least half a billion years. Phylogenetic analyses of individual polyomavirus genes suggest that some modern polyomavirus species arose after ancient recombination events involving distantly related polyomavirus lineages. The improved evolutionary model provides a useful platform for developing a more accurate taxonomic classification system for the viral family Polyomaviridae. PMID:27093155

    Macromolecular complexes are essential to conserved biological processes, but their prevalence across animals is unclear. By combining extensive biochemical fractionation with quantitative mass spectrometry, here we directly examined the composition of soluble multiprotein complexes among diverse metazoan models. Using an integrative approach, we generated a draft conservation map consisting of more than one million putative high-confidence co-complex interactions for species with fully sequenced genomes that encompasses functional modules present broadly across all extant animals. Clustering reveals a spectrum of conservation, ranging from ancient eukaryotic assemblies that have probably served cellular housekeeping roles for at least one billion years, ancestral complexes that have accrued contemporary components, and rarer metazoan innovations linked to multicellularity. We validated these projections by independent co-fractionation experiments in evolutionarily distant species, affinity purification and functional analyses. The comprehensiveness, centrality and modularity of these reconstructed interactomes reflect their fundamental mechanistic importance and adaptive value to animal cell systems. PMID:26344197

    The second part embraces exclusively the main characteristics of the medicine in Ancient Mesopotamia, in its main facets: concept of disease, healers and practice. The disease was considered a divine punishment or resultant from a malign influence. Insofar, the medicine began by being preventive, by the use of appropriate amulets or by offerings or sacrifices intending to pacify those malign forces. The treatment of the generality of the diseases privileged the expulsion of those spirits and malign influences from the patient body, purifying it, which was done by the specific intervention of a approximately shipu (clergymanexorcist); not having results, the treatment was continued by the asû (practical healer) that appealed to a group of physical manipulations, limited surgical acts and the administration or application of prescriptions, resultants of the mixture of organic and inorganic substances. In case of failing, the patients (as well as common healthy individuals or rule leaders) could fall back upon a priest diviner (bârû) that, by examination of the organs of an animal especially sacrificed for, would give a final decision about the disease or the future. Besides this more occult facet, nourished in religious faiths and in the magic, the medicine of Ancient Mesopotamia included rational knowledge, certainly as the result of systematic patients observation and semiotic interpretation. From those observations and knowledge referred to the Sumerian period, carefully logged, refined and transmitted to the following generations, it was built a valuable group of texts with the description of symptoms, signs, diagnosis and prognostic of the most common diseases, still identifiable in the present.

    Science Education With or For Native Americans?: An Analysis of the Native American Science Outreach Network (NASON), is the study of a summer institute for science teachers and Native American para-professionals and students in the Department of Chemistry at the University of Washington (UW) from 1992-1996. The study determines effects of NASON in schools, in tribal communities and on Native American students. It clarifies processes through which tribal communities and academic institutions can jointly design and implement education programs and curricula that reflect values and traditions of tribal communities and western education. Incorporated in the study is also an analysis of meanings of "Indian" identity, "Indian" education vis a vis education in general, and "Indian" science and "western" science, explored against the background of school experiences for Indian students. This research study examines NASON with regard to principles that are basic to applied anthropology, considering the following issues: (1) How well did NASON reflect an understanding of tribal and school values and cultures? (2) How effectively were the needs, wants and values of the people reflected in the program? (3) What cultural patterns were reflected in NASON's structure? (4) How did NASON consider the impact of its program on whole communities? (5) How did NASON ascertain and address motivations of its participants? (6) How did tribal community members or secondary teachers participate in planning and implementing NASON? (7) How were key tribal and academic community leaders involved? (8) What procedures were used? (9) Did NASON's structure discourage ethnocentrism? (10) How did NASON leadership work with rather than for Indian people and teachers? The study concludes that educational programs must be designed and monitored by an Advisory Board that includes equal representation of Tribes and Elders, Families, School personnel, and University representatives, considering the effect

    We apply decision theory in a structured decision-making framework to evaluate how control of raccoons (Procyon lotor), a native predator, can promote the conservation of a declining population of American Oystercatchers (Haematopus palliatus) on the Outer Banks of North Carolina. Our management objective was to maintain Oystercatcher productivity above a level deemed necessary for population recovery while minimizing raccoon removal. We evaluated several scenarios including no raccoon removal, and applied an adaptive optimization algorithm to account for parameter uncertainty. We show how adaptive optimization can be used to account for uncertainties about how raccoon control may affect Oystercatcher productivity. Adaptive management can reduce this type of uncertainty and is particularly well suited for addressing controversial management issues such as native predator control. The case study also offers several insights that may be relevant to the optimal control of other native predators. First, we found that stage-specific removal policies (e.g., yearling versus adult raccoon removals) were most efficient if the reproductive values among stage classes were very different. Second, we found that the optimal control of raccoons would result in higher Oystercatcher productivity than the minimum levels recommended for this species. Third, we found that removing more raccoons initially minimized the total number of removals necessary to meet long term management objectives. Finally, if for logistical reasons managers cannot sustain a removal program by removing a minimum number of raccoons annually, managers may run the risk of creating an ecological trap for Oystercatchers.

    Bueno Watts, Nievita

    Climate change is not a thing of the future. Indigenous people are being affected by climate changes now. Native American Earth scientists could help Native communities deal with both climate change and environmental pollution issues, but are noticeably lacking in Earth Science degree programs. The Earth Sciences produce the lowest percentage of minority scientists when compared with other science and engineering fields. Twenty semi-structured interviews were gathered from American Indian/ Alaska Native Earth Scientists and program directors who work directly with Native students to broaden participation in the field. Data was analyzed using qualitative methods and constant comparison analysis. Barriers Native students faced in this field are discussed, as well as supports which go the furthest in assisting achievement of higher education goals. Program directors give insight into building pathways and programs to encourage Native student participation and success in Earth Science degree programs. Factors which impede obtaining a college degree include financial barriers, pressures from familial obligations, and health issues. Factors which impede the decision to study Earth Science include unfamiliarity with geoscience as a field of study and career choice, the uninviting nature of Earth Science as a profession, and curriculum that is irrelevant to the practical needs of Native communities or courses which are inaccessible geographically. Factors which impede progress that are embedded in Earth Science programs include educational preparation, academic information and counseling and the prevalence of a Western scientific perspective to the exclusion of all other perspectives. Intradepartmental relationships also pose barriers to the success of some students, particularly those who are non-traditional students (53%) or women (80%). Factors which support degree completion include financial assistance, mentors and mentoring, and research experiences. Earth scientists

    Full Text Available The existence of passive makers in Kurdish language, similar to that of ancient Iranian languages can be very helpful in linguistic studies, language change and finding the nature of passive structures in modern Iranian languages such as Persian. The writers of this article have found a passive maker in Kurdish language and its dialects such as Sorani, Ardalani, Kalhori, Ilami and Horami that like ancient Iranian languages is added to the verb root to form passive structures. This morpheme in Kurdish language appears as /ya/ and /ya^/ which is similar to /ya/ in ancient Iranian languages.

    A case is reported here of an ancient schwannoma in the retroperitoneum. The findings of abdominal ultrasound and CT in a patient with a retroperitoneal ancient schwannoma are presented, and the clinical and radiological features of this unusual tumour are reviewed. The presence of a large, well-delineated complex cystic mass in the deep soft tissues should raise the possibility of an ancient schwannoma. It is important to recognize these tumours as benign with excellent prognosis so as to avoid unnecessary radical surgery. Copyright (1998) Blackwell Science Pty Ltd

    Already in ancient times did medical liability occupy mankind. Various civilizations did give their own interpretation on the subject and proposed solutions. Original writings are rare and articles concerning ancient medical liability equally are hard to find. The only relatively trustworthy sources are of legal nature and find their origin in Greek philosophy and Roman Law. At a later stage, Arabic philosophers gave a renewed view on the statements of these previous civilizations and added their own way of thinking. All these influences still reflect in our modern western way of medical acting. Some of these ancient customs concerning medical liability will be discussed in this article. PMID:20690537

    A recent study suggested that increased copy numbers of the AMY2B gene might be a crucial genetic change that occurred during the domestication of dogs. To investigate AMY2B expansion in ancient breeds, which are highly divergent from modern breeds of presumed European origins, we analysed copy numbers in native Japanese dog breeds. Copy numbers in the Akita and Shiba, two ancient breeds in Japan, were higher than those in wolves. However, compared to a group of various modern breeds, Akitas had fewer copy numbers, whereas Shibas exhibited the same level of expansion as modern breeds. Interestingly, average AMY2B copy numbers in the Jomon-Shiba, a unique line of the Shiba that has been bred to maintain their appearance resembling ancestors of native Japanese dogs and that originated in the same region as the Akita, were lower than those in the Shiba. These differences may have arisen from the earlier introduction of rice farming to the region in which the Shiba originated compared to the region in which the Akita and the Jomon-Shiba originated. Thus, our data provide insights into the relationship between the introduction of agriculture and AMY2B expansion in dogs. PMID:26358734

    2009-01-01

    The present work summarizes the more elucidating aspects on the foundations and the practice of the medicine in Antique Mesopotamia, since the invention of the writing, more than 5000 thousand years ago, and the beginning of our era. The first part of the article includes a brief perspective about the political and social evolution that characterized those archaic civilizations, as well as the inventions and knowledge further used by the following Humanity's generations. Most of what is known on the subject, as well as the history and political-social events that occurred in the region during that remote epoch, resulted of the laborious decoding of about half a million small clay plates or fragments with text engravings in cuneiform characters that were discovered since the middle of the XIX century in the ruins of the main cities of the Babylonian and Assyrian empires. The second part embraces exclusively the main characteristics of the medicine in Ancient Mesopotamia, in its main facets: concept of disease, healers and practice. The disease was considered a divine punishment or resultant from a malign influence. In that base, the medicine began by being preventive, by the use of appropriate amulets, or by offerings or sacrifices intending to pacify those malign forces. The treatment of the generality of the diseases privileged the expulsion of those spirits and malign influences from the patient body, purifying it, which was done by the specific intervention of an ãshipu (clergyman-exorcist); not having results, the treatment was continued by the asû (practical healer) that appealed to a group of physical manipulations, limited surgical acts and the administration or application of prescriptions, resultants of the mixture of organic and inorganic substances.

    2016-02-01

    Full Text Available Background: Although notable health disparities related to alcohol use persist among Alaska Native people living in rural communities, there is a paucity of research examining drinking behaviour in particular segments of this population, including elders. One explanation for this is the distrust of behavioural health research in general and alcohol research in particular following the legacy of the Barrow Alcohol Study, still regarded as a notable example of ethics violations in cross-cultural research. Objective: The present study reports findings from one of the first research studies asking directly about alcohol abuse among rural Alaska Natives (AN since the study in Barrow took place in 1979. Design: We report findings regarding self-reported alcohol use included in an elder needs assessment conducted with 134 Alaska Native elders from 5 rural villages off the road system in Alaska. Data were collected in partnership between academic researchers and community members in accordance with the principles of Community-Based Participatory Research. Results: Findings showed very high rates of sobriety and low rates of alcohol use, contradicting stereotypes of widespread alcohol abuse among AN. Possible explanations and future research directions are discussed. Conclusions: This research represents one step forward in mending academic–community relationships in rural Alaska to further research on alcohol use and related health disparities.

    2012-08-01

    Recently two developments have had a major impact on the field of ancient DNA (aDNA). First, new advances in DNA sequencing, in combination with improved capture/enrichment methods, have resulted in the recovery of orders of magnitude more DNA sequence data from ancient animals. Second, there has been an increase in the range of tissue types employed in aDNA. Hair in particular has proven to be very successful as a source of DNA because of its low levels of contamination and high level of ancient endogenous DNA. These developments have resulted in significant advances in our understanding of recently extinct animals: namely their evolutionary relationships, physiology, and even behaviour. Hair has been used to recover the first complete ancient nuclear genome, that of the extinct woolly mammoth, which then facilitated the expression and functional analysis of haemoglobins. Finally, we speculate on the consequences of these developments for the possibility of recreating extinct animals. PMID:22674514

    Deeb, C.; Walter, P.; Castaing, J.; Penhoud, P.; Veyssière, P.

    The processing technologies available during the time of ancient Egypt are of present concern to the field of Archaeology and Egyptology. Materials characterization is the best tool for establishing the processing history of archaeological objects. In this study, transmission electron microscopy (TEM) is used, in addition to other techniques, for phase identification and study of the microstructure and characteristic defect structures in ancient Egyptian cosmetic powders. These powders generally consist of a mix of Pb-containing mineral phases: galena (PbS), cerussite (PbCO3), and phosgenite (Pb2Cl2CO3), among others. Modern materials are fabricated according to recipes found in ancient texts to mimic the processing of ancient times and to compare with the archaeological specimens. In particular, a comparison between the dislocation structures of PbS crystals deformed in the laboratory and PbS from archaeological specimens from the collections of the Louvre Museum is presented .

  7. No rheumatoid arthritis in ancient Egypt: a reappraisal.

    Science.gov (United States)

    Kwiecinski, Jakub; Rothschild, Bruce M

    2016-06-01

    Antiquity of rheumatoid arthritis (RA) remains controversial, and its origins in Americas or in the Old World are disputed. Proponents of the latter frequently refer to RA in ancient Egypt, but validity of those claims has never been examined. Review of all reported RA cases from ancient Egypt revealed that none of them represent real RA, instead being either examples of changing naming conventions or of imprecise diagnostic criteria. Most cases represented osteoarthritis or spondyloarthropathies. Also review of preserved ancient Egyptian medical writings revealed many descriptions of musculoskeletal disorders, but none of them resembled RA. This suggests that RA was absent in ancient Egypt and supports the hypothesis of the New World origin of RA and its subsequent global spread in the last several centuries. PMID:26650735

    Keller, D.; Hom, E.

    Recent regional surface surveys have placed more focus on rural investigations, but the means of transport and communication within those rural surroundings has not always received adequate attention. The Southern Euboea Exploration Project has undertaken a new phase of research in the Karystos area with the goal of developing a methodology that allows for a more detailed record of the pre-modern land routes. On the Paximadhi peninsula it was possible to identify numerous fragments of suspected ancient routes dating to the Classical and Hellenistic periods. In the majority of cases these fragments were closely associated with adjacent datable ancient sites. By taking into consideration the evidence recorded during the survey it was sometimes possible to propose the extension of these ancient segments and to theorize the directions, lengths, and purposes of ancient networks.

  9. Deep sequencing of RNA from ancient maize kernels.

    Directory of Open Access Journals (Sweden)

    Sarah L Fordyce

    Full Text Available The characterization of biomolecules from ancient samples can shed otherwise unobtainable insights into the past. Despite the fundamental role of transcriptomal change in evolution, the potential of ancient RNA remains unexploited - perhaps due to dogma associated with the fragility of RNA. We hypothesize that seeds offer a plausible refuge for long-term RNA survival, due to the fundamental role of RNA during seed germination. Using RNA-Seq on cDNA synthesized from nucleic acid extracts, we validate this hypothesis through demonstration of partial transcriptomal recovery from two sources of ancient maize kernels. The results suggest that ancient seed transcriptomics may offer a powerful new tool with which to study plant domestication.

  10. Ancient Hydrothermal Springs in Arabia Terra, Mars

    Science.gov (United States)

    Oehler, Dorothy Z.; Allen, Carlton C.

    2008-01-01

    Hydrothermal springs are important astrobiological sites for several reasons: 1) On Earth, molecular phylogeny suggests that many of the most primitive organisms are hyperthermophiles, implying that life on this planet may have arisen in hydrothermal settings; 2) on Mars, similar settings would have supplied energy- and nutrient-rich waters in which early martian life may have evolved; 3) such regions on Mars would have constituted oases of continued habitability providing warm, liquid water to primitive life forms as the planet became colder and drier; and 4) mineralization associated with hydrothermal settings could have preserved biosignatures from those martian life forms. Accordingly, if life ever developed on Mars, then hydrothermal spring deposits would be excellent localities in which to search for morphological or chemical remnants of that life. Previous attempts to identify martian spring deposits from orbit have been general or limited by resolution of available data. However, new satellite imagery from HiRISE has a resolution of 28 cm/pixel which allows detailed analysis of geologic structure and geomorphology. Based on these new data, we report several features in Vernal Crater, Arabia Terra that we interpret as ancient hydrothermal springs.

  11. The rehabilitation of ancient gas factory sites

    International Nuclear Information System (INIS)

    In France, the inheritance of ancient town gas factories, mainly under the responsibility of Gaz de France, has left pollutants in the soils of their sites. The aim of the national company is to control these pollutants. Several hundred of town gas factories were exploited in France from 1798 (date of the invention of the process by Lebon) to the end of the 60's. The town gas, obtained from high temperature pyrogenic decomposition of coal, led to by-products which were stored or mixed with the soil. This paper describes the environmental and quality policy carried out by Gaz de France to characterize and remove the pollutants (coke, clinker, tar, phenols, ammoniated water, hydrogen sulphide, cyanides, benzene, toluene, xylenes..) to evaluate the risks of exposure of contaminants and their possible impact on human health. A method with 17 criteria was elaborated to characterize the sites and the rehabilitation comprises three steps: the environmental audit (evaluation of the concentration of pollutants and of their possible environmental and human impact), the complementary analysis (extension of the contaminated area, nature and concentration of pollutants, geologic and hydrogeologic characterisation of the site), and the rehabilitation itself when necessary (confinement or elimination of pollutants using thermal, physico-chemical or biological treatments).

  12. Mummification in the Ancient and New World.

    Science.gov (United States)

    Rosso, Ana Maria

    2014-01-01

    In the Ancient and New World there was a custom to preserve the corpse in a natural and artificial way. Since Paleolithic man believed in an afterlife and even in Mesoamerica and the Andes cultures, care and ceremony were practiced to the burial of the dead in an ancestral cult. Mortuary rituals were developed in Pre-dynastic Egypt (4500-3100 BC) but apparently they had begun before in America, c. 5000 BC. Mummies served for assisting the soul to survive and for preventing the dead from frightening the livings. Incas arrived at a point of perfection in these practices after other Andean cultures but we should not forget their older predecessors, the Chinchorro culture on the arid coast of the Atacama Desert. Different steps in the technique can be distinguished in both worlds: natural desiccation covered by animal skins, methods to protect the body skin and flesh removal, replacement with clay; black, red or mud-coated corpses, evisceration, body cavity treatment, cleansing and anointing the interior, brain removal, mummified bodies, corpses covered with natron, before being washed and bandaged or wrapped.

    Full Text Available Background: Trephination, or trepanning, is considered to be one of the most ancient surgical operations with an especially extensive geographical incidence, both in the New World and in the Old. In Europe, more than 200 finds of trephination have been found, from Scandinavia to the Balkans. The technique of trephination or trepanning covers overall the last 10,000 years and exhibits great versatility and adjustability in the knowledge, technical means, therapeutic needs, prejudices and social standards of each period and of each population group. Hippocrates was the one to classify for the first time the kinds of cranial fractures and define the conditions and circumstances for carrying out a trepanning.Aim: The present research aims to investigate the Greek cranial trephinations on sculls from the collection of the Anthropological Museum of the Medical School of Athens that come from archaeological excavations.Method: Skulls were examined by macroscopic observation with reflective light. Furthermore, radiographic representation of the skulls was used.Results: The anthropological researches and the studies of anthropological skeleton remains that came out during archaeological excavations from different eras and areas have given information about the medical practices in the very important geographic area of Greece and in particular, we referred to cases of Greek trephinations.

    Full Text Available Human T-lymphotropic virus (HTLV-1 is an ancient pathogen for human being but arising and recognized recently. The routes of transmission are vertical (mainly by breastfeeding, unsafe sexual contacts and through contaminated blood components specially in whom need frequent and repeated blood transfusions such as permanent anemia due to blood loss in hemophilia and major thalassemia. Patients who should undergo hemodialysis in their lifelong are another instance for increased risk of HTLV-1 exposure. The main HTLV-1-associated diseases are tropical spastic tetraparesis (HAM/TSP, an inflammatory myelopathy and adult T-cell leukemia (ATL. Although HTLV-1 is scattered around the world, only in endemic areas where prevalence rate is more than 1%, viral burden of infection have accumulated. Japan, Southern and Central parts of Africa, Caribbean basin and Iran are examples of endemic areas of HTLV-1. In this article, a rapid and brief review of HTLV-1 virology, immunology and pathogenesis have emerged. In addition, a short debate has driven about current statues of HTLV-1 in Iran.

  15. [Treatment for dystocia in ancient China].

    2012-05-01

    Treatment for dystocia in ancient China includes delivery taboo, delivery promotion decoction and midwifery methods. Before the Sui and Tang dynasties, delivery was more like a rite. In the Sui and Tang dynasties, doctors began to understand dystocia from the physical condition, delivery environment and psychological factors, and the delivery taboo was rejected. After that period, the delivery taboo became a folk custom and was separated from the field of medicine. The herbs for delivery promotion decoctions usually used the principle of regulating the blood and removing stasis and were of slippery character during and before the Tang dynasty. In the Song dynasty promotion decoction was enlarged. In later ages some doctors put forward that emphasis should be on conformity to nature and nursing, not dependence on promotion drugs. Before and during the Tang dynasty, acupuncture and salt smearing had been key methods for abnormal fetal position and there were also case recordings. In the Northern Song dynasty, these two methods were no longer used and the midwife's skill was emphasized. With more and more focus on the midwife's skill, some male doctors depended on midwives and some criticism of midwives also increased. The book Dashengbian reflected maximum distrust of midwives.

    Several arguments have been forwarded for the stagnation of Ayurveda, and most of these focus on the discrimination that Ayurveda faces under Mughal and then under British rule. Even for Ancient India, the halcyon portrait of Ayurveda synergetically related with religion and politics during the period, as has been portrayed in many books of history and in countless lores, is false. This paper then deals with the interaction between the State and Ayurvedic medicine in ancient India.

    The quality of spatial analyses of biodiversity is improved by (i) utilizing study areas with well defined physiogeographical boundaries, (ii) limiting the impact of widespread species, and (iii) using taxa with heterogeneous distributions. These conditions are typically met by ecosystems such as oceanic islands or ancient lakes and their biota. While research on ancient lakes has contributed significantly to our understanding of evolutionary processes, statistically sound studies of spatial ...

    The characterization of biomolecules from ancient samples can shed otherwise unobtainable insights into the past. Despite the fundamental role of transcriptomal change in evolution, the potential of ancient RNA remains unexploited - perhaps due to dogma associated with the fragility of RNA. We hypothesize that seeds offer a plausible refuge for long-term RNA survival, due to the fundamental role of RNA during seed germination. Using RNA-Seq on cDNA synthesized from nucleic acid extracts, we v...

    Although many community-based prevention interventions are conducted in American Indian and Alaska Native (AI/AN) communities, few studies report the outcomes. This article is a mixed methods outcome evaluation of an HIV/AIDS, hepatitis, and substance abuse prevention intervention for an urban AI/AN community, Native Voices. The study group wascomposed of 100youth (ages 13 to 18) who lived in the San Francisco Bay Area. The outcome measures of interest were knowledge, perception of risk, sexual self-efficacy, ethnic identity, and sexual risk behavior. The findings indicate that knowledge, perception of risk, and sexual self-efficacy increased, while no change was shown in measures of ethnic identity and behavior. Findings extended prior research by evaluating the Gathering of Native Americans (GONA) curriculum, a promising intervention designed for AI/AN people. PMID:22400468

  16. The Sea Peoples, from cuneiform tablets to carbon dating.

    David Kaniewski

    Full Text Available The 13(th century BC witnessed the zenith of the Aegean and Eastern Mediterranean civilizations which declined at the end of the Bronze Age, ∼3200 years ago. Weakening of this ancient flourishing Mediterranean world shifted the political and economic centres of gravity away from the Levant towards Classical Greece and Rome, and led, in the long term, to the emergence of the modern western civilizations. Textual evidence from cuneiform tablets and Egyptian reliefs from the New Kingdom relate that seafaring tribes, the Sea Peoples, were the final catalyst that put the fall of cities and states in motion. However, the lack of a stratified radiocarbon-based archaeology for the Sea People event has led to a floating historical chronology derived from a variety of sources spanning dispersed areas. Here, we report a stratified radiocarbon-based archaeology with anchor points in ancient epigraphic-literary sources, Hittite-Levantine-Egyptian kings and astronomical observations to precisely date the Sea People event. By confronting historical and science-based archaeology, we establish an absolute age range of 1192-1190 BC for terminal destructions and cultural collapse in the northern Levant. This radiocarbon-based archaeology has far-reaching implications for the wider Mediterranean, where an elaborate network of international relations and commercial activities are intertwined with the history of civilizations.

    In the late 1800s, John Wesley Powell, the second director of the U.S. Geological Survey (USGS), followed his interest in the tribes of the Great Basin and Colorado Plateau and studied their cultures, languages, and surroundings. From that early time, the USGS has recognized the importance of Native knowledge and living in harmony with nature as complements to the USGS mission to better understand the Earth. Combining traditional ecological knowledge with empirical studies allows the USGS and Native American governments, organizations, and people to increase their mutual understanding and respect for this land. The USGS is the earth and natural science bureau within the U.S. Department of the Interior (DOI) and is not responsible for regulations or land management. Climate change is a major current issue affecting Native lives and traditions throughout the United States. Climate projections for the coming century indicate an increasing probability for more frequent and more severe droughts in the Southwest, including the Navajo Nation. Erosion has claimed Native homes in Alaska. Fish have become inedible due to diseases that turn their flesh mushy. Native people who rely on or who are culturally sustained by hunting, fishing, and using local plants are living with climate change now. The traditional knowledge of Native peoples enriches and confirms the work of USGS scientists. The results are truly synergistic-greater than the sum of their parts. Traditional ecological knowledge is respected and increasingly used in USGS studies-when the holders of that knowledge choose to share it. The USGS respects the rights of Native people to maintain their patrimony of traditional ecological knowledge. The USGS studies can help Tribes, Native organizations, and natural resource professionals manage Native lands and resources with the best available unbiased data and information that can be added to their traditional knowledge. Wise Native leaders have noted that traditional

    2004-09-01

    This paper describes and analyses changes in food composition and nutritional preferences among the Chukchi and Yupik of coastal Chukotka in the last 15 years. The economic collapse of the infrastructure of Chukotka region has resulted in many indigenous northerners reverting to the traditional subsistence economy. Relatively expensive market foods are being replaced by cheaper ones, and by more readily available local foods. Percent contribution of proteins, lipids and carbohydrates to total caloric intake has not changed substantially, but sources of the major nutrients have become different. In 1985, local marine mammals accounted for about half of the consumed meat (55%), while in 2000 the share of it increased to 89 %. Market fats and oils are also being substituted by the fat of marine mammals. However, the contemporary diet of the natives of coastal Chukotka differs significantly from the traditional one. The meat of seals and gray whales (small sized and less dangerous to harvest) remains seasonally accessible, but can not be stored for long times. There is an insufficient amount of walrus and bowhead whale meat, which can be prepared in traditional style by fermentation, and stored for a long time. This probably also provides a specific protection against Helicobacter pylori. The young people today are more oriented towards local food-stuff: 76 % Coastal Chukchee and Yupik under the age of 30 indicated a preference for native foods over European ("Russian") ones, while this share is lower (66 %) among people older than 30 years. Overall, 86 % of natives consider that whale hunting, as the main source of food, should be increased (in 1985, only 45% suggested so). PMID:15526927

  20. Digital Natives Coming of Age: Challenges for Managers

    2014-10-01

    Full Text Available Youth unemployment is currently a stringent problem in many European countries. Most of the time, both the public opinion and the national and European institutions blame the economic crisis, the social conditioning of these youngsters, and point to the failure of the educational systems to provide them with the necessary qualifications needed on the market. There are a few initiatives, such as the Youth Guarantee launched in 2013, led by European public authorities in order to reduce this phenomenon, but these initiatives address solely the professional proficiency of the youngsters. And most authorities perceive them as citizens who need to be trained to fit with the existing working environments. The situation is, in fact, more complex, as todays youngsters are different from the previous generations in terms of the values they share and the basic way they process information. When speaking of the youth, the high unemployment rate due to system imbalance between people training and work fields’ requirements are just one side of the coin. The other side speaks about the impact digital technology has upon young people, favouring the emergence of the so called digital natives, and about the fact that the working environment in itself has to incorporate changes in order to accommodate these youngsters and fully benefit from their capabilities.     As Romanian digital natives come of age, minimizing the mind gap between elder managers and younger employees and candidates becomes an important issue that companies increasingly have to deal with. This article explores the digital natives’ expectations from their managers and from the companies they aim to work for, based upon a survey conducted in four universities in Bucharest. We propose a series of recommendations for managers who work closely with digital natives, in order to improve the work environment and create the premises for better job performance in their teams, possibly reducing
