    Genome-wide data, both from SNP arrays and from complete genome sequencing, are becoming increasingly abundant and are now even available from extinct hominins. These data are providing new insights into population history; in particular, when combined with model-based analytical approaches, genome-wide data allow direct testing of hypotheses about population history. For example, genome-wide data from both contemporary populations and extinct hominins strongly support a single dispersal of modern humans from Africa, followed by two archaic admixture events: one with Neanderthals somewhere outside Africa and a second with Denisovans that (so far) has only been detected in New Guinea. These new developments promise to reveal new stories about human population history, without having to resort to storytelling.

  2. Approaches to the History of Patients: From the Ancient World to Early Modern Europe.

    This chapter looks from an early modernist's perspective at some of the major questions and methodological issues that writing the history of patients in the ancient world shares with similar work on Patientengeschichte in medieval and early modern Europe. It addresses, in particular, the problem of finding adequate sources that give access to the patients' experience of illness and medicine and highlights the potential as well as the limitations of using physicians' case histories for that purpose. It discusses the doctor-patient relationship as it emerges from these sources, and the impact of the patient's point of view on learned medical theory and practice. In conclusion, it pleads for a cautious and nuanced approach to the controversial issue of retrospective diagnosis, recommending that historians consistently ask in which contexts and in what way the application of modern diagnostic labels to pre-modern accounts of illness can truly contribute to a better historical understanding rather than distort it.

    With its large size, complex topography and high number of avian endemics, Hispaniola appears to be a likely candidate for the in situ speciation of its avifauna, despite the worldwide rarity of avian speciation within single islands. We used multilocus comparative phylogeography techniques to examine the pattern and history of divergence in 11 endemic birds representing potential within-island speciation events. Haplotype and allele networks from mitochondrial ND2 and nuclear intron loci reveal a consistent pattern: phylogeographic divergence within or between closely related species is correlated with the likely distribution of ancient sea barriers that once divided Hispaniola into several smaller paleo-islands. Coalescent and mitochondrial clock dating of divergences indicate species-specific response to different geological events over the wide span of the island's history. We found no evidence that ecological or topographical complexity generated diversity, either by creating open niches or by restricting long-term gene flow. Thus, no true within-island speciation appears to have occurred among the species sampled on Hispaniola. Divergence events predating the merging of Hispaniola's paleo-island blocks cannot be considered in situ divergence, and postmerging divergence in response to episodic island segmentation by marine flooding probably represents in situ vicariance or interarchipelago speciation by dispersal. Our work highlights the necessity of considering island geologic history while investigating the speciation-area relationship in birds and other taxa. © 2011 Blackwell Publishing Ltd.

    Safe clinical practice is based on a sound knowledge of the structure and function of the human body. Thus, knowledge of anatomy has been an essential tool in the practice of healthcare throughout the ages. The history of anatomy in India traces from the Paleolithic Age to the Indus Valley Civilization, the Vedic Times, the Islamic Dynasties, the modern Colonial Period, and finally to Independent India. The course of the study of anatomy, despite accompanying controversies and periods of latencies, has been fascinating. This review takes the reader through various periods of Indian medicine and the role of anatomy in the field of medical practice. It also provides a peek into the modern system of pedagogy in anatomical sciences in India. Copyright © 2013 American Association of Anatomists.

    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. Furthermore, eDNA can reflect the biodiversity of extant flora and fauna, both qualitatively and quantitatively, allowing detection of rare species. As such, trace studies of plant and vertebrate DNA in the environment have revolutionized our knowledge of biogeography. However, the approach remains marred by biases related to DNA behaviour in environmental settings, incomplete reference databases and false positive results due to contamination. We provide a review of the field. PMID:25487334

    Recent advances in sequencing technologies and molecular methods have facilitated the sequencing of DNA from ancient human remains which has, in turn, provided unprecedented insight into human history. Within the past 4 years the genomes of Neandertals and Denisovans, as well as the genomes of at least two early modern humans, have been sequenced. These sequences showed that there have been several episodes of admixture between modern and archaic groups; including admixture from Neandertals into modern human populations outside of Africa, and admixture from Denisovans into modern human populations in Oceania. Recent results indicate that some of these introgressed regions may have been advantageous for modern humans as they expanded into new regions outside of Africa. Copyright © 2014.

    The History and Practice of Ancient Astronomy combines new scholarship with hands-on science to bring readers into direct contact with the work of ancient astronomers. While tracing ideas from ancient Babylon to sixteenth-century Europe, the book places its greatest emphasis on the Greek period, when astronomers developed the geometric and philosophical ideas that have determined the subsequent character of Western astronomy. The author approaches this history through the concrete details of ancient astronomical practice. Carefully organized and generously illustrated, the book can teach reade

    The genus Equus is richly represented in the fossil record, yet our understanding of taxonomic relationships within this genus remains limited. To estimate the phylogenetic relationships among modern horses, zebras, asses and donkeys, we generated the first data set including complete mitochondrial sequences from all seven extant lineages within the genus Equus. Bayesian and Maximum Likelihood phylogenetic inference confirms that zebras are monophyletic within the genus, and the Plains and Grevy's zebras form a well-supported monophyletic group. Using ancient DNA techniques, we further characterize the complete mitochondrial genomes of three extinct equid lineages (the New World stilt-legged horses, NWSLH; the subgenus Sussemionus; and the Quagga, Equus quagga quagga). Comparisons with extant taxa confirm the NWSLH as being part of the caballines, and the Quagga and Plains zebras as being conspecific. However, the evolutionary relationships among the non-caballine lineages, including the now-extinct subgenus Sussemionus, remain unresolved, most likely due to extremely rapid radiation within this group. The closest living outgroups (rhinos and tapirs) were found to be too phylogenetically distant to calibrate reliable molecular clocks. Additional mitochondrial genome sequence data, including radiocarbon dated ancient equids, will be required before revisiting the exact timing of the lineage radiation leading up to modern equids, which for now were found to have possibly shared a common ancestor as far as up to 4 Million years ago (Mya).

  20. Ancient medical texts, modern reading problems

    Full Text Available The word tradition has a very specific meaning in linguistics: the passing down of a text, which may have been completed or corrected by different copyists at different times, when the concept of authorship was not the same as it is today. When reading an ancient text the word tradition must be in the reader's mind. To discuss one of the problems an ancient text poses to its modern readers, this work deals with one of the first printed medical texts in Portuguese, the Regimento proueytoso contra ha pestenença, and draws a parallel between it and two related texts, A moche profitable treatise against the pestilence, and the Recopilaçam das cousas que conuem guardar se no modo de preseruar à Cidade de Lixboa E os sãos, & curar os que esteuerem enfermos de Peste. The problems which arise out of the textual structure of those books show how difficult is to establish a tradition of another type, the medical tradition. The linguistic study of the innumerable medieval plague treatises may throw light on the continuities and on the disruptions of the so-called hippocratic-galenical medical tradition.

    In this second part of ancient Chinese surgical history, the practice of bone setting in China began around 3000 years ago. Throughout this period, significant progress was made, some highlights of which are cited. These methods, comparable with Western orthopaedic technique, are still being practised today. In conclusion, the possible reasons for the lack of advancement in operative surgery are discussed, within context of the cultural, social and religious background of ancient China.

  3. Defining Astrology in Ancient and Classical History

    Science.gov (United States)

    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.

  5. Ancient Chinese Observations and Modern Cometary Models

    Yeomans, D. K.

    1995-12-01

    Ancient astronomical observations by Chinese, Japanese, and Korean observers represent the only data source for discerning the long-term behavior of comets. The primary source material is derived from Chinese astrologers who kept a vigilant celestial watch in an effort to issue up-to-date astrological forecasts for the reigning emperors. Surprisingly accurate records were kept on cometary apparitions with careful notes being made of an object's position, motion, size, color, and tail length. For comets Halley, Swift-Tuttle, and Tempel-Tuttle, Chinese observations have been used to model their motions over two millennia and to infer their photometric histories. One general result is that active comets must achieve an apparent magnitude of 3.5 or brighter before they become obvious naked-eye objects. For both comets Halley and Swift-Tuttle, their absolute magnitudes and hence their outgassing rates, have remained relatively constant for two millennia. Comet Halley's rocket-like outgassing has consistently delayed the comet's return to perihelion by 4 days so that the comet's spin axis must have remained stable for at least two millennia. Although its outgassing is at nearly the same rate as Halley's, comet Swift-Tuttle's motion has been unaffected by outgassing forces; this comet is likely to be ten times more massive than Halley and hence far more difficult for rocket-like forces to push it around. Although the earliest definite observations of comet Tempel-Tuttle were in 1366, the associated Leonid meteor showers have been identified as early as A.D. 902. The circumstance for each historical meteor shower and storm have been used to guide predictions for the upcoming 1998-1999 Leonid meteor displays.

    2009-12-01

    Although surgery was an accepted and quite proficient craft very early on in Chinese history, it has deteriorated through the ages. Despite the fact that anaesthetic agents in major surgery were employed during the third century, Chinese surgery is conspicuous by its stagnation. Reverence for the dead, filial piety, abhorrence of shedding blood and other conservative attitudes make it impossible for any accurate knowledge of the human anatomy and physiology, without which surgery cannot progress. This article surveys some highlights in the history of surgery in ancient China and examines the factors responsible for its decline. The second concluding part deals with orthopaedics.

  8. Ancient and modern women in the "Woman's World".

    Hurst, Isobel

    2009-01-01

    Under the editorship of Oscar Wilde, the "Woman's World" exemplified the popular dissemination of Hellenism through periodical culture. Addressing topics such as marriage, politics, and education in relation to the lives of women in the ancient world, the magazine offered an unfamiliar version of the reception of ancient Greece and Rome in late-Victorian aestheticism, one that was accessible to a wide readership because it was often based on images rather than texts. The classical scholar Jane Ellen Harrison addressed herself to this audience of women readers, discussing the similarities between modern collegiate life and the "woman's world" that enabled Sappho to flourish in ancient Greece. The "Woman's World" thus questions gender stereotypes by juxtaposing ancient and modern women, implicitly endorsing varied models of womanhood.

The end of the political nexus between theology and politics, the evanescence of nation-state sovereignty, the check of great historical interpretations reveal the necessity of new categories and new organizational models, able to make us answer to the violence that the ongoing processes are liberating. Schiera underlines in particular the relevance of the administrative apparatus because of its capacity to link the global government with global organization, human rights and the commons.

    Hall, John A

    2011-09-01

    This essay drews attention to two books on empires by historians which deserve the attention of sociologists. Bang's model of the workings of the Roman economy powerfully demonstrates the tributary nature of per-industrial tributary empires. Darwin's analysis concentrates on modern overseas empires, wholly different in character as they involved the transportation of consumption items for the many rather than luxury goods for the few. Darwin is especially good at describing the conditions of existence of late nineteenth century empires, noting that their demise was caused most of all by the failure of balance of power politics in Europe. Concluding thoughts are offered about the USA. © London School of Economics and Political Science 2011.

  16. Are Historical Observations ``Ancient'' or ``Modern''?

    Science.gov (United States)

    Griffin, R. Elizabeth

    2016-10-01

    The demarcation between ``old'', ``historic'' and ``heritage'' is fuzzy. To a large degree it depends upon purpose and usefulness, and it will always be subjective. At what point does the intrinsic value of an historic item outpace the mystique associated just with its age? When, for instance, does an ``old'' car become a ``vintage'' car? When do archived astronomical records contribute something of quantitative value to science? When can they be extricated from the realms of the museum and placed in the context of modern research? Celestial objects vary. Some do so explosively, often irreversibly; many vary periodically over time-scales from a hour or less to a century or more. Furthermore, all celestial objects change as they evolve, mostly so slowly as to be practically imperceptible, but while the general time-scale of that evolution is millions of years there are a few stages (such as the collapse from AGB towards planetary nebula and white dwarf) which happen rather suddenly, and invaluable examples of ``before-after'' can be found in some plate stores. Astrophysics has a comprehensive need to investigate the nature and time-scales of all types of change, especially ones which only access to its ``heritage'' data can describe. Surely in this day and age we have enough tools, capacity and technologies to fulfil such a basic requirement? The frustrating answer is that we do have some of the necessary tools, and most of the technologies, but as a community we lack ``capacity'' if that means manpower and funds. The problem is a technical one of accessing the older data in useable formats; it was generated by the universal change in detector technology from photography to electronic device, an exciting development in efficiency and scope that heralded a new era of research capability and data management, archiving and sharing, but it left pre-digital photographic data right out of the picture. Developments of that nature should have made research more inclusive

    The genetic relationship of past modern humans to today's populations and each other was largely unknown until recently, when advances in ancient DNA sequencing allowed for unprecedented analysis of the genomes of these early people. These ancient genomes reveal new insights into human prehistory not always observed studying present-day populations, including greater details on the genetic diversity, population structure, and gene flow that characterized past human populations, particularly in early Eurasia, as well as increased insight on the relationship between archaic and modern humans. Here, we review genetic studies on ∼45000- to 7500-year-old individuals associated with mainly preagricultural cultures found in Eurasia, the Americas, and Africa. Copyright © 2017 Elsevier Ltd.

  19. Roots of political corruption in ancient history

    Full Text Available Corruption has always been regarded as a special form of enrichment, based on prohibited and unethical grounds. Hence 'political corruption' could be defined as the immorality of the powerful; as the use of political power for the purpose of getting rich without any legal basis. Immorality of the powerful is the root of all the abuses that occur in the society. Those who are at the top of the pyramid of power have been particularly prominent in acquiring as large a fortune as possible. The phenomenon of 'political corruption' has been known in all societies, from the oldest to modern ones. In the ancient civilization of Mesopotamia, there was an established custom of reciprocity between deliberate gifts and requested services. This phenomenon could be observed with Pericles, who is, among other things, attributed the idea of compensation for participation in state affairs. The phenomenon of 'political corruption' is referred to in Cicero's Rome, where bribery as a form of wealth acquisition without legal basis was formally condemned, but also widespread. Even today we can see that there are powerful persons who persist in the violation or circumvention of rules which guide any structured society: their wealth originates from the enormous acquisition of material things, but also the acquisition of various privileges which they are not entitled to, such as titles, promotions, etc. They are the ones who have brought about the demise of the Latin sentence that the basis of any developed society is: 'To live an honest life, hurt no one, and grant everyone their due.'.

    Were teachers, of the early modern era not longing for the present? Most colleges of that time did not offer a history course. Still, they did teach a lot about the past since the teaching consisted in the reading of the works of ancient writers. This is because ancient science and literature were considered much more advanced than the science and…

  2. Environmental deterioration of ancient and modern hydraulic mortars (EDAMM)

    Environmental damage to ancient and modern mortars (EDAMM) is a European Commission funded project in which three European research institutes from Belgium, Spain and Italy have been collaborating. The project has provided a better understanding of the role of environmental pollution on the deterioration of ancient and modern hydraulic mortars. Recent monuments built in the 19th and 20th century, were constructed using these types of hydraulic mortars. Increasing numbers of these monuments need restoration all over Europe. Similar hydraulic mortars have been widely used in treatments carried out during last and the present century. Tests have been carried out on the identification of historic hydraulic mortars, on the evaluation of damage on samples taken from historic buildings and on the laboratory simulations carried out to investigate damage mechanisms. Among pollutants, SO{sub 2} is the main component of pollution causing damage to hydraulic mortars. Hydraulic mortars have been identified as the most sensitive building materials because of the formation of primary and secondary damage products, such as ettringite and thaumasite. Although the important implications of these results are for the development of conservation strategies for monuments and historic buildings, they are also of great relevance to the development of sustainable construction methods as the building industry still uses these materials today.

  3. Ancient-modern concordance in Ayurvedic plants: some examples.

    1999-10-01

    Ayurveda is the ancient (before 2500 b.c.) Indian system of health care and longevity. It involves a holistic view of man, his health, and illness. Ayurvedic treatment of a disease consists of salubrious use of drugs, diets, and certain practices. Medicinal preparations are invariably complex mixtures, based mostly on plant products. Around 1,250 plants are currently used in various Ayurvedic preparations. Many Indian medicinal plants have come under scientific scrutiny since the middle of the nineteenth century, although in a sporadic fashion. The first significant contribution from Ayurvedic materia medica came with the isolation of the hypertensive alkaloid from the sarpagandha plant (Rouwolfia serpentina), valued in Ayurveda for the treatment of hypertension, insomnia, and insanity. This was the first important ancient-modern concordance in Ayurvedic plants. With the gradual coming of age of chemistry and biology, disciplines central to the study of biologic activities of natural products, many Ayurvedic plants have been reinvestigated. Our work on Commiphora wightti gum-resin, valued in Ayurveda for correcting lipid disorders, has been described in some detail; based on these investigations, a modern antihyperlipoproteinemic drug is on the market in India and some other countries. There has also been concordance for a few other Ayurvedic crude drugs such as Asparagus racemosus, Cedrus deodara, and Psoralea corylifolia.

    The rich fossil record of the family Equidae (Mammalia: Perissodactyla) over the past 55 MY has made it an icon for the patterns and processes of macroevolution. Despite this, many aspects of equid phylogenetic relationships and taxonomy remain unresolved. Recent genetic analyses of extinct equids have revealed unexpected evolutionary patterns and a need for major revisions at the generic, subgeneric, and species levels. To investigate this issue we examine 35 ancient equid specimens from four geographic regions (South America, Europe, Southwest Asia, and South Africa), of which 22 delivered 87-688 bp of reproducible aDNA mitochondrial sequence. Phylogenetic analyses support a major revision of the recent evolutionary history of equids and reveal two new species, a South American hippidion and a descendant of a basal lineage potentially related to Middle Pleistocene equids. Sequences from specimens assigned to the giant extinct Cape zebra, Equus capensis, formed a separate clade within the modern plain zebra species, a phenotypicically plastic group that also included the extinct quagga. In addition, we revise the currently recognized extinction times for two hemione-related equid groups. However, it is apparent that the current dataset cannot solve all of the taxonomic and phylogenetic questions relevant to the evolution of Equus. In light of these findings, we propose a rapid DNA barcoding approach to evaluate the taxonomic status of the many Late Pleistocene fossil Equidae species that have been described from purely morphological analyses.

    Full Text Available In recent years, researchers and practitioners are increasingly interested in the role and influence of the forms of business organization on the economy and society. Interpretations of the role of companies in the modern period, ranging from enthusiastic support (as the most important invention of capitalism, an explanation of the Western civilization’s expansion to moderate and often critical positions, where the company is seen as a solution, not necessarily optimal, to market imperfections. On the other hand, we often ponder upon the explanation of political, administrative and infrastructural success of ancient Rome: the state or the enterprise (the private initiative? Closer to our time, we rediscover with amazement that the "dark" Middle Ages are not at all dark and lacking in progress, at least in terms of capitalist organization and logic. The development of trade in the two poles of medieval Europe (the Mediterranean and the BaltoScandinavian area, of industry and trade in the North-Western quadrant (Flanders and neighbouring regions, was concurrent with the improvement of organizational forms of business, with the diversity and flexibility of entrepreneurial or even corporate frameworks. Of course, the study of historical sources (ancient or medieval cannot provide direct answers or solutions to the questions of modern society, because the challenges of today are rather different to those of the past. On the other hand, understanding history can help companies to build a more complete and a wiser enterprise functionality and role in the modern society, to reformulate the questions and to find new solutions. Our paper, with a clear juridical perspective on economic history, focuses on the organization of firms in ancient Rome and medieval Europe, tries to provide examples, useful interpretations and diverse solutions to the problems of contemporary society and economy.

    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

  9. Brain architecture and social complexity in modern and ancient birds.

    Burish, Mark J; Kueh, Hao Yuan; Wang, Samuel S-H

    2004-01-01

    Vertebrate brains vary tremendously in size, but differences in form are more subtle. To bring out functional contrasts that are independent of absolute size, we have normalized brain component sizes to whole brain volume. The set of such volume fractions is the cerebrotype of a species. Using this approach in mammals we previously identified specific associations between cerebrotype and behavioral specializations. Among primates, cerebrotypes are linked principally to enlargement of the cerebral cortex and are associated with increases in the complexity of social structure. Here we extend this analysis to include a second major vertebrate group, the birds. In birds the telencephalic volume fraction is strongly correlated with social complexity. This correlation accounts for almost half of the observed variation in telencephalic size, more than any other behavioral specialization examined, including the ability to learn song. A prominent exception to this pattern is owls, which are not social but still have very large forebrains. Interpolating the overall correlation for Archaeopteryx, an ancient bird, suggests that its social complexity was likely to have been on a par with modern domesticated chickens. Telencephalic volume fraction outperforms residuals-based measures of brain size at separating birds by social structure. Telencephalic volume fraction may be an anatomical substrate for social complexity, and perhaps cognitive ability, that can be generalized across a range of vertebrate brains, including dinosaurs.

    Neurosurgical treatment of diseases dates back to prehistoric times and the trephination of skulls for various maladies. Throughout the evolution of trephination, surgery and religion have been intertwined to varying degrees, a relationship that has caused both stagnation and progress. From its mystical origins in prehistoric times to its scientific progress in ancient Egypt and its resurgence as a well-validated surgical technique in modern times, trephination has been a reflection of the cultural and religious times. Herein we present a brief history of trephination as it relates religion, culture, and the evolution of neurosurgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    1997-01-01

    Up to 43 glaze and body samples of ancient and modern Chinese Jun Porcelain and other porcelain are chosen and contents of 36 elements for each sample are determined by NAA. The NAA data are then analysed by the fuzzy cluster method. The result shows that although the ancient Jun Porcelain samples span leaped 600 years and are from different kilns and their glaze colors are utterly different, they have a long-term, stable and mainly the same supply of raw material. The relation between ancient Jun Porcelain and ancient Ru Porcelain is also preliminarily analysed. It is found that only few modern Jun Porcelain samples are similar to ancient Jun Porcelain but the majority of them are different from ancient ones

    2015-12-01

    Full Text Available 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 methodological parameters of the ensuing 22 monographs with case studies — as well as 12 unpublished manuscripts, and through international conferences initiated a wider dialogue on ancient cities beyond the classical Greek world. It was the first interdisciplinary study that attempted to tackle the environmental factors, together with the social and economic ones, underpinning the creation, development and operation of ancient Greek cities. Doxiadis’s innovative approach to the analysis of the ancient city was indebted to his practice as an architect and town planner and was informed by his theory of Ekistics. His purpose was to identify the urban planning principles of ancient Greek settlements in order to employ them in his projects. This paper examines the concept and methodology of the AGC project as well as the ways in which Doxiadis used the study of ancient cities in relation to his contemporary urban/architectural agendas, and explains this important moment in the historiography of ancient Greek urbanism.

  16. Genotyping of Capreolus pygargus fossil DNA from Denisova cave reveals phylogenetic relationships between ancient and modern populations.

    Directory of Open Access Journals (Sweden)

    Nadezhda V Vorobieva

    Full Text Available BACKGROUND: The extant roe deer (Capreolus Gray, 1821 includes two species: the European roe deer (C. capreolus and the Siberian roe deer (C. pygargus that are distinguished by morphological and karyotypical differences. The Siberian roe deer occupies a vast area of Asia and is considerably less studied than the European roe deer. Modern systematics of the Siberian roe deer remain controversial with 4 morphological subspecies. Roe deer fossilized bones are quite abundant in Denisova cave (Altai Mountains, South Siberia, where dozens of both extant and extinct mammalian species from modern Holocene to Middle Pleistocene have been retrieved. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed a 629 bp fragment of the mitochondrial control region from ancient bones of 10 Holocene and four Pleistocene Siberian roe deer from Denisova cave as well as 37 modern specimen belonging to populations from Altai, Tian Shan (Kyrgyzstan, Yakutia, Novosibirsk region and the Russian Far East. Genealogical reconstructions indicated that most Holocene haplotypes were probably ancestral for modern roe deer populations of Western Siberia and Tian Shan. One of the Pleistocene haplotypes was possibly ancestral for modern Yakutian populations, and two extinct Pleistocene haplotypes were close to modern roe deer from Tian Shan and Yakutia. Most modern geographical populations (except for West Siberian Plains are heterogeneous and there is some tentative evidence for structure. However, we did not find any distinct phylogenetic signal characterizing particular subspecies in either modern or ancient samples. CONCLUSION/SIGNIFICANCE: Analysis of mitochondrial DNA from both ancient and modern samples of Siberian roe deer shed new light on understanding the evolutionary history of roe deer. Our data indicate that during the last 50,000 years multiple replacements of populations of the Siberian roe deer took place in the Altai Mountains correlating with climatic changes. The Siberian

  17. The history of parkinsonism: descriptions in ancient Indian medical literature.

    Ovallath, Sujith; Deepa, P

    2013-05-01

    The clinical syndrome of parkinsonism was identified in ancient India even before the period of Christ and was treated methodically. The earliest reference to bradykinesia dates to 600 bc. Evidences prove that as early as 300 bc, Charaka proposed a coherent picture of parkinsonism by describing tremor, rigidity, bradykinesia, and gait disturbances as its components. The scenario was further developed by Madhava, Vagbhata, and Dalhana all through history. The 15th-century classic "Bhasava rajyam" introduced the term kampavata, which may be regarded as an ayurvedic analogue of parkinsonism. The pathogenesis of kampavata centered on the concept of imbalance in the vata factor, which controls psychomotor activities. The essential element in therapy was the administration of powdered seed of Mucuna pruriens, or atmagupta, which as per reports, contains 4%-6% of levodopa. In addition to proving the existence and identification of parkinsonism in ancient India, the study points to the significance of ancient Indian Sanskrit works in medical history.

    2009-10-01

    Full Text Available Abstract The origins of Western culture extensively relate to Ancient Greek culture. While many ancient cultures have contributed to our current knowledge about medicine and the origins of psychiatry, the Ancient Greeks were among the best observers of feelings and moods patients expressed towards medicine and toward what today is referred to as 'psychopathology'. Myths and religious references were used to explain what was otherwise impossible to understand or be easily communicated. Most ancient myths focus on ambiguous feelings patients may have had towards drugs, especially psychotropic ones. Interestingly, such prejudices are common even today. Recalling ancient findings and descriptions made using myths could represent a valuable knowledge base for modern physicians, especially for psychiatrists and their patients, with the aim of better understanding each other and therefore achieving a better clinical outcome. This paper explores many human aspects and feelings towards doctors and their cures, referring to ancient myths and focusing on the perception of mental illness.

  19. Whose global art (history?: Ancient art as global art

    Directory of Open Access Journals (Sweden)

    Cynthia Colburn

    2016-12-01

    Full Text Available Discourse on global art or art history arguably dominates the field of art history today in terms of curriculum and research. This discourse cuts across time and space, impacting all art historical specializations, from prehistoric to contemporary, and from Africa to the Americas. Yet, the mainstream theoretical discourse on global art or art history focuses almost explicitly on contemporary and, to a lesser extent, modern art, operating from the premise that only these arts were created in an age of globalization and, thus, emphasize hybridity. This essay seeks to expand the mainstream theoretical discourse regarding global art to pre-modern examples, given that artistic exchange and hybridity dates as early as the prehistoric era all over the world and is not dependent on newer technologies. Indeed, one might argue that the study of pre-modern examples of global art could provide a powerful historical lens through which to analyze contemporary global art.

    Nowadays the higher nutritional value of whole grains compared to refined grains is recognized. In the last decade, there has been a renewed interest in the ancient wheat varieties for producing high-value food products with enhanced health benefits. This study compared two ancient grains, two heritage grains, and four modern grains grown in the same agronomic conditions considering not only their chemical characteristics, but also their biological effects. Whole grain flours were obtained and used to make bread. Bread was in vitro digested, the digesta were supplemented to HepG2 cells, and the biological effects of supplementation were evaluated. In addition, cells previously supplemented with the different digested bread types were then exposed to inflammatory agents to evidence possible protective effects of the pre-treatments. Despite the impossibility to discriminate bread made with different grains based on their chemical composition, results herein reported evidence that their supplementation to cultured cells exerts different effects, confirming the potential health benefits of ancient grains. This research represents an advancement for the evaluation of the apparent positive effects of ancient grains and the formulation of cereal-based products with added nutritional value.

    Full Text Available The necessity of research on higher spiritual and self-regulative capacities in the context of ancient oriental system of knowledge is expressed. The historical and psychological methods of studying ancient knowledge are described. The methods of the history of psychology, proposed by the author, are used: such as the method of revealing scientific knowledge reserves, aimed at restoring and practical mastering the psychological heritage of ancient times, as well as the experimental method, involving the verification of psychological facts, phenomena and laws described in ancient texts, with the help of modern scientific research methods (observation, experiment, statistical data. Meditative practices and philosophical concepts of Buddhism are considered from the standpoint of modern psychology. The ancient Buddhist meditative practices “Contemplation of the mind”, linked to the concept of “mindfulness” is described. It is concluded that the concept of the mind is the key in the Buddhist system of knowledge. The understanding of the mind in the ancient Buddhist doctrine is compared with a modern interpretation of the concept of “mind” in psychological science, as well as its content is revealed due to psychological terms “higher self-regulative capacities” and “moral-value aspect of spiritual capacities”. It is revealed that in the Buddhist system of knowledge there can be seen close links between higher self-regulative capacities and moral-value aspect of spiritual capacities. The results of empirical studies of the ancient meditative practices and their positive impact on self-regulation of the modern people are submitted.

  7. The Beginnings of the History of Philosophy in Ancient Greece

    Directory of Open Access Journals (Sweden)

    Ignacija J. Fridl

    2010-12-01

    Full Text Available Like many contemporary researchers into the ancient history of philosophy and into encyclopedic Hellenistic works (Mejer, Schoefield, Runia, Maasfeld ..., the author observes that a great deal of research into ancient doxography and Diogenes Laertius has focused on evaluation. Her own paper, on the other hand, turns to the question: What can Laertius’ attention to philosophers’ biographies in his Lives and Opinions of Eminent Philosophers tell us about the Ancient Greek view of the philosophical thought from the past?  As noted by the author, the term ‘doxography’ itself, which bears the connotation of a less reliable source and is applied today to almost every ancient explanation of any philosophical doctrine, was established by Hermann Diels as late as the 19th century. Yet this view of earlier thought was in fact already developed by Aristotle. His treatise On the Soul defines the philosophical tenets of his precursors as ‘opinions’, which are then critically examined and rejected. This attitude to earlier philosophy informs all Aristotle’s writings and his methodology of philosophy in general, for his prima philosophia as a ‘science which considers the truth’ is founded precisely on the critique of earlier thought. He critically evaluates even the tenets of his teacher Plato, in order to surpass him with his own philosophy. Thus he lays the foundations of evolutionary historiography, which perceives history as a spiritual progress and has lasted through Hegel, Marx, and – with a negative historical connotation – Heidegger – to this day. Plato, by contrast, envisages, through the very form of the dialogue, the relation to earlier philosophy as a conversation, a constant interweaving and fertilisation of one’s own thought with the wisdom of one’s precursors. This perception is further reinforced by his doctrine of knowledge as a process of remembering, that is, of philosophy as a road to wisdom leading back

  8. Sun-earth connection education through modern views of ancient

    Science.gov (United States)

    Thieman, J. R.

    The NASA Sun-Earth Connection Education Forum (SECEF) has the responsibility of using the latest science results from the study of solar physics, space physics, and aeronomy to inspire students in the classroom and to inform the public in general. SECEF works with NASA's Sun-Earth Connection spaceflight missions to accomplish this goal. Each year the missions and SECEF combine to promote their science through a major event designed to attract the attention of all. In late 2004 and 2005 the event will be the study of solar observatories created by ancient peoples and a comparison of their knowledge and culture to present understanding. Two solar observatory sites will be featured, Chaco Canyon in the U.S. and Chichen Itza in Mexico. There are many other places throughout the world that could also be featured as solar observatories and some of these may be described on the SECEF web site or used in future occurrences. Special emphasis is placed on events associated with the solstice and equinox dates. It is hoped that there will be happenings around the world on these days and SECEF will work with many museums, science centers, and other groups to help make this happen. Plans for the 2005 Ancient Observatories event and possible future events on the same subject will be described.

    Pregnancy-associated glycoproteins (PAGs) constitute a multigenic family of aspartic proteinases expressed in the trophoblast of the ruminant placenta. In Bos taurus, this family comprises 21 members segregated into ancient and modern phylogenetic groups. Ancient PAGs have been reported to be synthesized throughout the trophoblastic cell layer whereas modern PAGs are produced by binucleate cells of cotyledons. The aim of this study was to investigate modern and ancient PAGs during gestation in cotyledonary and intercotyledonary tissues. To obtain convincing and innovative results despite the high sequence identity shared between PAGs, we designed specific tools such as amplification primers and antibodies. Using real-time RT-PCR, we described the transcript expression of 16 bovine PAGs. Overall, PAGs are characterized by an increase in their expression during gestation. However, we demonstrated a segregation of modern PAGs in cotyledons and of ancient PAGs in the intercotyledonary chorion, except for the ancient PAG2 expressed in cotyledons. By raising specific antibodies against the modern PAG1 and ancient PAG11 and PAG2, we established the expression kinetics of the proteins using western blotting. Immunohistochemistry showed that PAGs were produced by specific cellular populations: PAG1 by binucleate cells in the whole trophoblastic layer, PAG11 was localized in binucleate cells of the intercotyledonary trophoblast and the chorionic plate of the cotyledon, while PAG2 was produced in mononucleate cells of the internal villi of the cotyledon. These results revealed a highly specific regulation of PAG expression and cell localization as a function of their phylogenetic status, suggesting distinct biological functions within placental tissues.

    To obtain more knowledge of the origin and genetic diversity of domestic horses in China, this study provides a comprehensive analysis of mitochondrial DNA (mtDNA) D-loop sequence diversity from nine horse breeds in China in conjunction with ancient DNA data and evidence from archaeological and historical records. A 247-bp mitochondrial D-loop sequence from 182 modern samples revealed a total of 70 haplotypes with a high level of genetic diversity. Seven major mtDNA haplogroups (A-G) and 16 clusters were identified for the 182 Chinese modern horses. In the present study, nine 247-bp mitochondrial D-loop sequences of ancient remains of Bronze Age horse from the Chifeng region of Inner Mongolia in China (c. 4000-2000a bp) were used to explore the origin and diversity of Chinese modern horses and the phylogenetic relationship between ancient and modern horses. The nine ancient horses carried seven haplotypes with rich genetic diversity, which were clustered together with modern individuals among haplogroups A, E and F. Modern domestic horse and ancient horse data support the multiple origins of domestic horses in China. This study supports the argument that multiple successful events of horse domestication, including separate introductions of wild mares into the domestic herds, may have occurred in antiquity, and that China cannot be excluded from these events. Indeed, the association of Far Eastern mtDNA types to haplogroup F was highly significant using Fisher's exact test of independence (P = 0.00002), lending support for Chinese domestication of this haplogroup. High diversity and all seven mtDNA haplogroups (A-G) with 16 clusters also suggest that further work is necessary to shed more light on horse domestication in China.

    Particle-size distributions yield valuable insight into processes controlling sediment supply, transport, and deposition in sedimentary systems. This is especially true in ancient deposits, where effects of changing boundary conditions and autogenic processes may be detected from deposited sediment. In order to improve interpretations in ancient deposits and constrain uncertainty associated with new methods for paleomorphodynamic reconstructions in ancient fluvial systems, we compare particle-size distributions in three active sand-bed rivers in central Nebraska (USA) to grain-size distributions from ancient sandy fluvial deposits. Within the modern rivers studied, particle-size distributions of active-layer, suspended-load, and slackwater deposits show consistent relationships despite some morphological and sediment-supply differences between the rivers. In particular, there is substantial and consistent overlap between bed-material and suspended-load distributions, and the coarsest material found in slackwater deposits is comparable to the coarse fraction of suspended-sediment samples. Proxy bed-load and slackwater-deposit samples from the Kayenta Formation (Lower Jurassic, Utah/Colorado, USA) show overlap similar to that seen in the modern rivers, suggesting that these deposits may be sampled for paleomorphodynamic reconstructions, including paleoslope estimation. We also compare grain-size distributions of channel, floodplain, and proximal-overbank deposits in the Willwood (Paleocene/Eocene, Bighorn Basin, Wyoming, USA), Wasatch (Paleocene/Eocene, Piceance Creek Basin, Colorado, USA), and Ferris (Cretaceous/Paleocene, Hanna Basin, Wyoming, USA) formations. Grain-size characteristics in these deposits reflect how suspended- and bed-load sediment is distributed across the floodplain during channel avulsion events. In order to constrain uncertainty inherent in such estimates, we evaluate uncertainty associated with sample collection, preparation, analytical

    Full Text Available Southeast Asia or Southeastern Asia, with more than six hundred million populations, is home to millions of Buddhists, Muslims, Confucians, Protestants, Catholics, and now Pentecostals, as well as many followers of local religions and spiritual beliefs. Notwithstanding its great historical, political, cultural legacies, however, the region has long been neglected as a site for religious studies in the Western academia. Aiming at filling the gap in Asian and religious studies as well as exploring the richness of Southeast Asian cultures, this article discusses the dynamics, diversity, and complexity of Southeast Asian societies in their response to the region’s richly political, cultural, and religious traditions spanning from pre-modern era to modern one. The article also examines the “integrative revolutions” that shaped and reshaped warfare, state organization and economics of Southeast Asia, particularly in the pre-European colonial era. In addition, the work discusses the wave of Islamization, particularly since the nineteenth century, as well as the upsurge of religious resurgence that shift the nature of religiosity and the formation of religious groupings in the area. The advent of Islam, with some interventions of political regimes, had been an important cause for the decline of Hindu-Buddhist traditions in some areas of Southeast Asia, especially Indonesia, the coming of Pentecostalism has challenged the well-established mainstream Protestantism and Catholicism, especially in Indonesia and the Philippines. Keywords: history, modernity, religious change, Southeast Asia

    2013-06-01

    Histories of science in India are revisitations of the colonial question. Science is ideology to be unraveled and exposed--as modernity and progress making or violence and oppression making--depending on where you stand on the interpretive spectrum. It has been seen as ideologically driven practice, as a mode of knowledge production whose history is inseparable from the social and political uses to which it is tethered. In the colonial as well as the postcolonial context, science and technology have been seen as the "ideology of empire," "tools of empire," "tentacles of progress," and "reasons of state." Yet science and technology are practices and bodies of knowledge that inhabitants of the subcontinent have engaged with enthusiasm, that they have used to invent themselves in their global, national, and individual lives. We know remarkably little about the histories of these complex engagements. A departure from current historiographical preoccupations is called for to map and explain the lives, institutions, practices, and stories of science on the subcontinent as they connect with, and where they break away from, the world at large.

  18. Climate History and the Modern World

    Science.gov (United States)

    Riebsame, William E.

    H. H. Lamb's latest book on the earth's changing climate is a carefully crafted work covering four areas: the physical basis of climate and climate change, the methods of climate reconstruction, the history of climate since the height of the last glaciation, and the impact of climate on human affairs. The book will be of particular interest to three groups. Atmospheric scientists interested in the long history of climate behavior (but perhaps overwhelmed by Lamb's all-encompassing work on the topic, Climate: Past, Present and Future, vol. II, Methuen, New York), will find Climate History and the Modern World to be a good titration of the fuller work. Scientists in other fields, including social scientists grappling with issues of climate-society interaction, will find the book a good entree into the field. Finally, Lamb himself suggests that the book will be useful to resource managers and other decision makers trying to avoid negative climate impacts. With this last audience in mind, no doubt, Lamb has chosen a style that eschews extensive footnoting and references (though sufficient citations are included to lead to further information). This works quite well and seems reasonable in view of his carefully documented previous writings.

    Fuzi is a medicine used for rescuing from collapse by restoring yang as well as a famous toxic traditional Chinese medicine. In order to ensure the efficacy and safe medication, Fuzi has mostly been applied after being processed. There have been different Fuzi processing methods recorded by doctors of previous generations. Besides, there have also been differences in Fuzi processing methods recorded in modern pharmacopeia and ancient medical books. In this study, the authors traced back to medical books between the Han Dynasty and the period of Republic of China, and summarized Fuzi processing methods collected in ancient and modern literatures. According to the results, Fuzi processing methods and using methods have changed along with the evolution of dynasties, with differences in ancient and modern processing methods. Before the Tang Dynasty, Fuzi had been mostly processed and soaked. From Tang to Ming Dynasties, Fuzi had been mostly processed, soaked and stir-fried. During the Qing Dynasty, Fuzi had been mostly soaked and boiled. In the modem times, Fuzi is mostly processed by being boiled and soaked. Before the Tang Dynasty, a whole piece of Fuzi herbs or their fragments had been applied in medicines; Whereas their fragments are primarily used in the modern times. Because different processing methods have great impacts on the toxicity of Fuzi, it is suggested to study Fuzi processing methods.

    Ecology and ethnobotany were integrated to assess the impact of ancient Maya tree-dominated home gardens (i.e., "forest gardens"), which contained a diversity of tree species used for daily household needs, on the modern tree species composition of a Mesoamerican forest. Researchers have argued that the ubiquity of these ancient gardens throughout Mesoamerica led to the dominance of species useful to Maya in the contemporary forest, but this pattern may be localized depending on ancient land use. The tested hypothesis was that species composition would be significantly different between areas of dense ancient residential structures (high density) and areas of little or no ancient settlement (low density). Sixty-three 400-m2 plots (31 high density and 32 low density) were censused around the El Pilar Archaeological Reserve in northwestern Belize. Species composition was significantly different, with higher abundances of commonly utilized "forest garden" species still persisting in high-density forest areas despite centuries of abandonment. Subsequent edaphic analyses only explained 5% of the species composition differences. This research provides data on the long-term impacts of Maya forests gardens for use in development of future conservation models. For Mesoamerican conservation programs to work, we must understand the complex ecological and social interactions within an ecosystem that developed in intimate association with humans.

    Conclusion: In this study it was observed that the genetic diversity among Mtb strains and, in particular between ancient and modern strains, reflects on several aspects of host-pathogen interaction. In particular, the modulation of specific cellular microRNAs upon MTBC infection suggests a potential role for these microRNAs in the outcome of infection and, to a major extent, to the different epidemiological success of Mtb strains.

  6. Do ancient types of wheat have health benefits compared with modern bread wheat?

    Science.gov (United States)

    Shewry, Peter R

    2018-01-01

    A number of studies have suggested that ancient wheats have health benefits compared with modern bread wheat. However, the mechanisms are unclear and limited numbers of genotypes have been studied, with a particular focus on Kamut ® (Khorasan wheat). This is important because published analyses have shown wide variation in composition between genotypes, with further effects of growth conditions. The present article therefore critically reviews published comparisons of the health benefits of ancient and modern wheats, in relation to the selection and growth of the lines, including dietary interventions and comparisons of adverse effects (allergy, intolerance, sensitivity). It is concluded that further studies are urgently required, particularly from a wider range of research groups, but also on a wider range of genotypes of ancient and modern wheat species. Furthermore, although most published studies have made efforts to ensure the comparability of material in terms of growth conditions and processing, it is essential that these are standardised in future studies and this should perhaps be a condition of publication.

  9. Ribosomal history reveals origins of modern protein synthesis.

    Directory of Open Access Journals (Sweden)

    Ajith Harish

    Full Text Available The origin and evolution of the ribosome is central to our understanding of the cellular world. Most hypotheses posit that the ribosome originated in the peptidyl transferase center of the large ribosomal subunit. However, these proposals do not link protein synthesis to RNA recognition and do not use a phylogenetic comparative framework to study ribosomal evolution. Here we infer evolution of the structural components of the ribosome. Phylogenetic methods widely used in morphometrics are applied directly to RNA structures of thousands of molecules and to a census of protein structures in hundreds of genomes. We find that components of the small subunit involved in ribosomal processivity evolved earlier than the catalytic peptidyl transferase center responsible for protein synthesis. Remarkably, subunit RNA and proteins coevolved, starting with interactions between the oldest proteins (S12 and S17 and the oldest substructure (the ribosomal ratchet in the small subunit and ending with the rise of a modern multi-subunit ribosome. Ancestral ribonucleoprotein components show similarities to in vitro evolved RNA replicase ribozymes and protein structures in extant replication machinery. Our study therefore provides important clues about the chicken-or-egg dilemma associated with the central dogma of molecular biology by showing that ribosomal history is driven by the gradual structural accretion of protein and RNA structures. Most importantly, results suggest that functionally important and conserved regions of the ribosome were recruited and could be relics of an ancient ribonucleoprotein world.

  10. The Hippocratic oath: A comparative analysis of the ancient text′s relevance to American and Indian modern medicine

    Directory of Open Access Journals (Sweden)

    Chandrakant I Jhala

    2012-01-01

    Full Text Available Hippocrates (460-375 B.C., an ancient Greek physician considered the "Father of Medicine," constructed the groundwork for the principles of ethics in medicine over 2,500 years ago in his establishment of the Hippocratic Oath. One of the oldest binding documents in history, the text has remained the ethical template for physicians to this day. The changing cultural and social environment of modern society, accompanied by the advancement in scientific knowledge and therapeutic tools, has surfaced the need to reframe ethical perspective in modern medicine. Progress in aspects such as organ transplantation, stem cell technology, and genetic engineering has welcomed a new set of ethical dilemmas. These dilemmas have become intimately intertwined with the impact of commercialization, as seen by the interplay between legislation, health care, and pharmaceutical businesses. This paper seeks to dissect the principles of the original Hippocratic Oath and analyze the template in relation to the ethical dilemmas presented by contemporary medicine. Examination will provide a deeper understanding of the paradigm shift in modern medical ethics. Both the value of the Oath and the level of awareness of modern ethical dilemmas through the lens of American and Indian medical graduates will be assessed.

    2009-06-01

    Primary fluid inclusions in halite crystallized in Saline Valley, California, in 1980, 2004-2005, and 2007, contain rod- and coccoid-shaped microparticles the same size and morphology as archaea and bacteria living in modern brines. Primary fluid inclusions from a well-dated (0-100,000 years), 90 m long salt core from Badwater Basin, Death Valley, California, also contain microparticles, here interpreted as halophilic and halotolerant prokaryotes. Prokaryotes are distinguished from crystals on the basis of morphology, optical properties (birefringence), and uniformity of size. Electron micrographs of microparticles from filtered modern brine (Saline Valley), dissolved modern halite crystals (Saline Valley), and dissolved ancient halite crystals (Death Valley) support in situ microscopic observations that prokaryotes are present in fluid inclusions in ancient halite. In the Death Valley salt core, prokaryotes in fluid inclusions occur almost exclusively in halite precipitated in perennial saline lakes 10,000 to 35,000 years ago. This suggests that trapping and preservation of prokaryotes in fluid inclusions is influenced by the surface environment in which the halite originally precipitated. In all cases, prokaryotes in fluid inclusions in halite from the Death Valley salt core are miniaturized (<1 μm diameter cocci, <2.5 μm long, very rare rod shapes), which supports interpretations that the prokaryotes are indigenous to the halite and starvation survival may be the normal response of some prokaryotes to entrapment in fluid inclusions for millennia. These results reinforce the view that fluid inclusions in halite and possibly other evaporites are important repositories of microbial life and should be carefully examined in the search for ancient microorganisms on Earth, Mars, and elsewhere in the Solar System.

  15. Climatic and physiological controls on the stable isotope composition of modern and ancient Cupressaceae

    Zinniker, D.; Tipple, B.; Pagani, M.

    2007-12-01

    Unique and abundant secondary metabolites found in waxes and resins of the Callitroid, Cupressoid, and Taxodioid clades of the Cupressaceae family can be identified and quantified in complex mixtures of sedimentary organic compounds. This unusual feature makes it possible to study relatively simple (taxon-specific) isotope systems back in time across the broad array of environments in which these conifers are found. Work on these systems can potentially provide both robust paleoenvironmental proxies (i.e. for source water δD and growing season relative humidity) and quantitative probes into the ecophysiology of these plants in modern and ancient environments. Our research focuses on three genera representing environmental end-members of Cupressaceae - Juniperus, Thuja, and Chamaecyparis - (1) across geographic and environmental gradients in the field, and (2) in specific Holocene and late Pleistocene environmental records. The latter research focuses on peat cores from New England and Oregon and fossil packrat middens from the southwestern United States. Modern transects highlight the sensitivity of Cupressaceae to climatic variables. These include both variables during growth (relative humidity, soil moisture, etc.) and variables affecting seasonal and diurnal growth rates (temperature, winter precipitation, insolation, microhabitat, etc.). Work on ancient records has demonstrated the sensitivity of these unique taxon-specific archives to both subtle and dramatic climate shifts during the Pleistocene and Holocene. This work will result in an improved understanding of climatic and physiological controls on the stable isotopic composition of modern and ancient Cupressaceae - and by extension, other arborescent gymnosperms and C3 plants - providing a framework for understanding more complexly sourced organic inputs to sediments, coals, and petroleum prior to the advent of C4 plants. This research also has direct implications for stratigraphic stable isotope studies

  16. History of development and modern condition of Chinese military psychology

    2017-12-01

    Full Text Available Background. Russian military psychology is actively analyzing the achievements gained over the years of its reform and with great interest turns to the military psychological experience of foreign armies. Acquaintance with this experience allows Russian military psychology to assess its place in the world military psychological science, to assess the dynamics and fidelity of the general direction of development. In this regard, it is quite interesting to get acquainted with the state, capabilities, and the most important guidelines for the development of the Chinese military psychology. Objective. The objective of this paper is to get acquainted with the invaluable experience of trial and error, ups and downs, stagnation and real breakthroughs, which can be learnt through getting acquainted with the history and modern functioning of the psychological structures of the Chinese army. Design. The paper considers the centuries-old history and a modern condition of military psychology in China. The methodological foundations of the Chinese military psychology are proved to be the philosophical ideas of Taoism, Confucianism and Buddhism. Theoretical sources Chinese military psychology is rooted in the writings of the great thinkers and generals of ancient China – Sun Tzu, Wu Tzu, Zhuge Liang. The two most vigorously developing areas of military psychology: the psychological selection of military personnel, theory and practice of psychological warfare.

    Incubation or temple sleep in sanctuaries of Aesculapius, Amphiaraos, Trophonios, etc., for the care of patients was practised even in the older times of ancient Greece and may be viewed as a form of psychotherapy and especially as 'dream-psychotherapy'. In Greek antiquity, as it is known, dreams were considered as a way of communication between gods and men. Survival of the custom of incubation exists even in our times in modern Greece, but are disappearing slowly. An attempt is made to find an explanation, if any, of those miraculous cures in accordance with the scientific thought of today.

  18. History, etymology, and fallacy: attitudes toward male masturbation in the ancient Western world.

    This article examines the attitudes toward male masturbation in the ancient western world. More specifically, this work deals with ancient Egypt, Greece, and Rome. By comparing each epoch and geographic region, intolerance of autoerotic activity can be seen. Although there is a pattern of intolerance, the act of masturbation is always viewed provisionally. In addition, by examining these three periods of history not only can attitudes be scrutinized, but also it can be seen quite clearly that there was no golden age of sexuality: The attitude of accepted and encouraged unlimited and varied sexual practices does not exist in the ancient western world. As in many other cultures in various stages of history, procreative sexuality is the dominating theme. Thus, current attitudes of sex are derived from, and still survive due to the influence of, ancient western civilization.

  19. Endogenous change: on cooperation and water in ancient history

    We propose and test the theory of endogenous change based on historical reconstructions of two ancient civilizations, Indus and Hohokam, in two water scarce basins, the Indus basin in the Indian subcontinent and the Lower Colorado basin in Southwestern United States. The endogenous institutional change sees changes in institutions as a sequence of equilibria brought about by changes in "quasi-parameters" such as rainfall, population density, soil and land use induced water resource availability. In the historical reconstructions of ancient civilizations, institutions are proximated by the scale of cooperation be it in the form of the extent of trade, sophisticated irrigation network, a centrally planned state or a loosely held state with a common cultural identity. The "quasi-parameters" either change naturally or are changed by humans and the changes affect the stability of cooperative structures over time. However, human influenced changes in the quasi-parameters itself are conditioned on the scale of existing cooperative structures. We thus provide insights into the quantitative dimensions of water access by ancient populations and its co-evolution with the socioeconomic and sociopolitical organization of the human past. We however do not suggest that water manipulation was the single most significant factor in stimulating social development and complexity - clearly this has been shown as highly reductionist, even misleading. The paper cautiously contributes to proximate prediction of hydrological change by attempting to understand the complexity of coupled human-hydrological systems.

    2008-06-01

    This study examines the genetic affinities of various modern human groupings using a multivariate analysis of morphometric data. Phylogenetic relationships among these groupings are also explored using neighbor-joining analysis of the metric data. Results indicate that the terminal Pleistocene/early Holocene fossils from Australasia exhibit a close genetic affinity with early modern humans from the Levant. Furthermore, recent human populations and Upper Paleolithic Europeans share a most recent common ancestor not shared with either the early Australasians or the early Levantine humans. This pattern of genetic and phylogenetic relationships suggests that the early modern humans from the Levant either contributed directly to the ancestry of an early lineage of Australasians, or that they share a recent common ancestor with them. The principal findings of the study, therefore, lend support to the notion of an early dispersal from Africa by a more ancient lineage of modern human prior to 50 ka, perhaps as early as OIS 5 times (76-100 ka).

    This paper examines the reception of the Stoic theory of the passions in the early modern period, highlighting various differences between the way notions such as (see symbol in text) (complete freedom from passions) and(see symbol in text) (pre-passions) were handled and interpreted by Continental and English authors. Both groups were concerned about the compatibility of Stoicism with Christianity, but came to opposing conclusions; and while the Continental scholars drew primarily on ancient philosophical texts, the English ones relied, in addition, on experience and observation, developing a natural history of the passions.

    Taxonomic over-splitting of extinct or endangered taxa, due to an incomplete knowledge of both skeletal morphological variability and the geographical ranges of past populations, continues to confuse the link between isolated extant populations and their ancestors. This is particularly problematic with the genus Equus. To more reliably determine the evolution and phylogeographic history of the endangered Asiatic wild ass, we studied the genetic diversity and inter-relationships of both extinct and extant populations over the last 100,000 years, including samples throughout its previous range from Western Europe to Southwest and East Asia. Using 229 bp of the mitochondrial hypervariable region, an approach which allowed the inclusion of information from extremely poorly preserved ancient samples, we classify all non-African wild asses into eleven clades that show a clear phylogeographic structure revealing their phylogenetic history. This study places the extinct European wild ass, E. hydruntinus, the phylogeny of which has been debated since the end of the 19th century, into its phylogenetic context within the Asiatic wild asses and reveals recent mitochondrial introgression between populations currently regarded as separate species. The phylogeographic organization of clades resulting from these efforts can be used not only to improve future taxonomic determination of a poorly characterized group of equids, but also to identify historic ranges, interbreeding events between various populations, and the impact of ancient climatic changes. In addition, appropriately placing extant relict populations into a broader phylogeographic and genetic context can better inform ongoing conservation strategies for this highly-endangered species.

  9. Sulfur isotope study of a modern intertidal environment, and the interpretation of ancient sulfides

    International Nuclear Information System (INIS)

    Chambers, L.A.

    1982-01-01

    Extensive sulfur isotope distribution data for sulfides precipitated in an intertidal environment show no distinctive features when compared with isotope values for other marine, sedimentary sulfides. The fractionation ranges from α = 1.030 to α = 1.048. The pattern is characteristic for a system essentially open to sulfate, and isotope analyses of interstitial sulfates are corroborative. A population of sulfate-reducing bacteria of the order of 10 9 organisms per cc of interstitial water is indicated. Seasonal variation of the isotope distribution reflects a transient sulfide composition and a bacterial population in which the fractionation effect is indirectly controlled by temperature. The data presented for this modern shallow water environment are at variance with an earlier assessment of isotopic distributions in ancient sulfides which linked shallow water environments with limited fractionation (α =< 1.025) in a closed system.

  12. Modernizing Natural History: Berkeley's Museum of Vertebrate Zoology in Transition.

    Sunderland, Mary E

    2013-01-01

    Throughout the twentieth century calls to modernize natural history motivated a range of responses. It was unclear how research in natural history museums would participate in the significant technological and conceptual changes that were occurring in the life sciences. By the 1960s, the Museum of Vertebrate Zoology at the University of California, Berkeley, was among the few university-based natural history museums that were able to maintain their specimen collections and support active research. The MVZ therefore provides a window to the modernization of natural history. This paper concentrates on the directorial transitions that occurred at the MVZ between 1965 and 1971. During this period, the MVZ had four directors: Alden H. Miller (Director 1940-1965), an ornithologist; Aldo Starker Leopold (Acting Director 1965-1966), a conservationist and wildlife biologist; Oliver P. Pearson (Director 1966-1971), a physiologist and mammalogist; and David B. Wake (Director 1971-1998), a morphologist, developmental biologist, and herpetologist. The paper explores how a diversity of overlapping modernization strategies, including hiring new faculty, building infrastructure to study live animals, establishing new kinds of collections, and building modern laboratories combined to maintain collections at the MVZ's core. The paper examines the tensions between the different modernization strategies to inform an analysis of how and why some changes were institutionalized while others were short-lived. By exploring the modernization of collections-based research, this paper emphasizes the importance of collections in the transformation of the life sciences.

    The development of Afrocentric historical writing is explored in this study which traces this recording of history from the Hellenistic-Roman period to the 19th century. Afrocentric writers are depicted as searching for the unique primary source of "culture" from one period to the next. Such passing on of cultural traits from the "ancient model" from the classical period to the origin of culture in Egypt and Africa is shown as being a product purely of creative history.

    We present an extensive ancient DNA analysis of mainly Neolithic cattle bones sampled from archaeological sites along the route of Neolithic expansion, from Turkey to North-Central Europe and Britain. We place this first reasonable population sample of Neolithic cattle mitochondrial DNA sequence diversity in context to illustrate the continuity of haplotype variation patterns from the first European domestic cattle to the present. Interestingly, the dominant Central European pattern, a starburst phylogeny around the modal sequence, T3, has a Neolithic origin, and the reduced diversity within this cluster in the ancient samples accords with their shorter history of post-domestic accumulation of mutation.

  16. Internal waves and modern and ancient hiatuses in pelagic caps of Pacific guyots and seamounts

    2013-04-01

    Locations of recent non-deposition and ancient hiatuses in the pelagic caps of guyots and seamounts are compared with paleotemperature and physiographic information to speculate on the character of internal tidal waves in the upper Pacific Ocean through the Cenozoic. Internal tidal waves are generated where the ocean barotropic tide passes over the Hawaiian and other major ridges in the Pacific basin. Drill core and geophysical evidence for sediment accumulation, non-deposition or erosion are used to classify broadly sites as either accumulating or eroding/non-depositing in the recent geological past. When these classified sites are compared against results of a numerical model of the internal tide field (Simmons, Ocean Mod. 2008), the sites accumulating particles over the past few million years are all found to lie away from beams of the modeled internal tide, while those that have not been accumulating are in areas of high internal wave energy. Given the correspondence to modern internal wave conditions, we examine whether internal tides can explain ancient hiatuses at the drill sites. For example, Late Cenozoic pelagic caps on guyots among the Marshall Islands contain two hiatuses of broadly similar age, but the dates of the first pelagic sediments deposited following each hiatus do not correlate between guyots, suggesting that they originate not from universal factors (e.g., water chemistry) but local, probably physical factors, such as internal tides. We investigate how changing boundary conditions such as ocean temperature and basin physiography may have affected the geometry and vigour of internal tides through the Cenozoic. Changes in the geometry of ridges underlying the Solomon, Bonin and Marianas Island chains caused by plate tectonics and subsidence may be responsible for sediment hiatuses at these far-field guyot sites.

    There is ongoing debate over how the water level and composition of the water in Lake Qinghai changed in the past and might change in future. This study of the microchemistry of otoliths from ancient naked carp explores the chemistry of a relict lake isolated from Lake Qinghai during the Little Ice Age (LIA). A close correlation between the ages measured on fish bone and otoliths by AMS-14C, and by optically stimulated luminescence on overlying sediments, confirms a high water level in Lake Qinghai before 680-300 years ago. The contrasting compositions of the ancient otoliths relative to modern otoliths and waters indicate that the relict lake became enriched in 18O, Mg, Li, B and to a lesser extent Ba, but depleted in 13C, owing to strong evaporation, authigenic carbonates precipitation, (micro-)organism activity, and less fresh water input after it was isolated. If there were long-term fresh water input, however, a reverse trend might occur. The most important observation is that, because the waters have been supersaturated with respect to carbonates, authigenic carbonate precipitation would result in low but consistent Sr/Ca ratios in the lakes, as recorded by both the ancient and modern otoliths. The geochemical records of ancient versus modern biogenic carbonates provide insights into the long-term hydroclimatic evolution processes of an inland water body.

    The study of biotropic effects of modern space weather carries the information about the rhythms and features of adaptation of early biological systems to the outer space influence. The influence of cosmic rays, ultraviolet waves and geomagnetic field on early life has its signs in modern biosphere processes. These phenomena could be experimentally studied on present-day biological objects. Particularly inorganic polyphosphates, so-called "fossil molecules", attracts special attention as the most ancient molecules which arose in inanimate nature and have been accompanying biological objects at all stages of evolution. Polyphosphates-containing graves of yeast's cells of Saccharomyces cerevisiae strain Y-517, , from the Ukrainian Collection of Microorganisms was studied by daily measurements during 2000-2013 years. The IZMIRAN daily data base of physiological parameters dynamics during 2000-2013 years were analyzed simultaneously (25 people). The analysis showed significant simultaneous changes of the statistical parameters of the studied biological systems in 2004 -2006. The similarity of simultaneous changes of adaptation strategies of human organism and the cell structures of Saccharomyces cerevisiae during the 23-24 cycles of solar activity are discussed. This phenomenon could be due to a replacement of bio-effective parameters of space weather during the change from 23rd to 24th solar activity cycle and nonstandard geophysical peculiarities of the 24th solar activity cycle. It could be suggested that the observed similarity arose as the optimization of evolution selection of the living systems in expectation of probable prolonged period of low solar activity (4-6 cycles of solar activity).

  19. Genes, Genomes, and Assemblages of Modern Anoxygenic Photosynthetic Cyanobacteria as Proxies for Ancient Cyanobacteria

    Grim, S. L.; Dick, G.

    2015-12-01

    Oxygenic photosynthetic (OP) cyanobacteria were responsible for the production of O2 during the Proterozoic. However, the extent and degree of oxygenation of the atmosphere and oceans varied for over 2 Ga after OP cyanobacteria first appeared in the geologic record. Cyanobacteria capable of anoxygenic photosynthesis (AP) may have altered the trajectory of oxygenation, yet the scope of their role in the Proterozoic is not well known. Modern cyanobacterial populations from Middle Island Sinkhole (MIS), Michigan and a handful of cultured cyanobacterial strains, are capable of OP and AP. With their metabolic versatility, these microbes may approximate ancient cyanobacterial assemblages that mediated Earth's oxygenation. To better characterize the taxonomic and genetic signatures of these modern AP/OP cyanobacteria, we sequenced 16S rRNA genes and conducted 'omics analyses on cultured strains, lab mesocosms, and MIS cyanobacterial mat samples collected over multiple years from May to September. Diversity in the MIS cyanobacterial mat is low, with one member of Oscillatoriales dominating at all times. However, Planktothrix members are more abundant in the cyanobacterial community in late summer and fall. The shift in cyanobacterial community composition may be linked to seasonally changing light intensity. In lab mesocosms of MIS microbial mat, we observed a shift in dominant cyanobacterial groups as well as the emergence of Chlorobium, bacteria that specialize in AP. These shifts in microbial community composition and metabolism are likely in response to changing environmental parameters such as the availability of light and sulfide. Further research is needed to understand the impacts of the changing photosynthetic community on oxygen production and the entire microbial consortium. Our study connects genes and genomes of AP cyanobacteria to their environment, and improves understanding of cyanobacterial metabolic strategies that may have shaped Earth's redox evolution.

  20. Ancient Greek Legend in Modern Japanese Literature: “Run, Melos!” by Dazai Osamu

    2017-12-01

    Full Text Available Dazai Osamu (1909-1948, a modern Japanese writer, wrote “Run, Melos!” in 1940. The short story is a rework of an Ancient Greek legend of Damon and Pythias from the 4th century B.C., which was introduced to Dazai through Schiller’s version of the legend, “The Hostage”. The legend, based on a true event, represents the perfect friendship and was reworked a number of times by different antique writers. After having been forgotten for a while, it reappeared in the Middle Ages as a fictional story and has gotten many new adaptations from then on. One of them was Schiller’s ballad in 1798, which – alongside an anecdote from Dazai’s own life – represented the basis for Dazai’s story. Even though “Run, Melos!” is not an autobiographical work, Dazai managed to pass his own feelings onto the characters, add some biblical elements, and included a never-before-employed dark twist in the story, thus making his version more realistic than the preceding ones. Despite the distance in time and place between him and the legend, with “Run, Melos!”, Dazai managed to retell a Western literature story, making it a part of the Japanese literature as well, adding motifs and themes influenced by his own life, time, and place.

    A detailed understanding of the spatiotemporal oxygenation of Earth's atmosphere-ocean system through the Precambrian has important implications for the environments capable of sustaining early eukaryotic life and the evolving oxidant budget of subducted sediments. Proxy records suggest an anoxic Fe-rich deep ocean through much of the Precambrian and atmospheric and surface-ocean oxygenation that started in earnest at the Paleoproterozoic Great Oxidation Event (GOE). The marine photic zone represented the initial site of oxygen production and accumulation via cyanobacteria, yet our understanding of surface-ocean oxygen contents and the extent and timing of oxygen propagation and exchange between the atmosphere and deeper ocean are limited. Here, we present an updated perspective of the constraints on atmospheric, surface-ocean, and deep-ocean oxygen contents starting at the GOE. Our research uses the iodine content of Proterozoic carbonates as a tracer of dissolved iodate in the shallow ocean, a redox-sensitive species quantitatively reduced in modern oxygen minimum zones. We supplement our understanding of the ancient record with novel experiments examining the rates of iodate production from oxygenated marine environments based on seawater incubations. Combining new data from iodine with published shallow marine (Ce anomaly, N isotopes) and atmospheric redox proxies, we provide an integrated view of the vertical redox structure of the atmosphere and ocean across the Proterozoic.

    2017-09-25

    Having served as a symbolic fruit since ancient times, pomegranate ( Punica granatum ) has also gained considerable recognition as a functional food in the modern era. A large body of literature has linked pomegranate polyphenols, particularly anthocyanins (ATs) and hydrolyzable tannins (HTs), to the health-promoting activities of pomegranate juice and fruit extracts. However, it remains unclear as to how, and to what extent, the numerous phytochemicals in pomegranate may interact and exert cooperative activities in humans. In this review, we examine the structural and analytical information of the diverse phytochemicals that have been identified in different pomegranate tissues, to establish a knowledge base for characterization of metabolite profiles, discovery of novel phytochemicals, and investigation of phytochemical interactions in pomegranate. We also assess recent findings on the function and molecular mechanism of ATs as well as urolithins, the intestinal microbial derivatives of pomegranate HTs, on human nutrition and health. A better understanding of the structural diversity of pomegranate phytochemicals as well as their bioconversions and bioactivities in humans will facilitate the interrogation of their synergistic/antagonistic interactions and accelerate their applications in dietary-based cancer chemoprevention and treatment in the future.

    Using functional metagenomics to study the resistomes of bacterial communities isolated from different layers of the Canadian high Arctic permafrost, we show that microbial communities harbored diverse resistance mechanisms at least 5,000 years ago. Among bacteria sampled from the ancient layers of a permafrost core, we isolated eight genes conferring clinical levels of resistance against aminoglycoside, β-lactam and tetracycline antibiotics that are naturally produced by microorganisms. Among these resistance genes, four also conferred resistance against amikacin, a modern semi-synthetic antibiotic that does not naturally occur in microorganisms. In bacteria sampled from the overlaying active layer, we isolated ten different genes conferring resistance to all six antibiotics tested in this study, including aminoglycoside, β-lactam and tetracycline variants that are naturally produced by microorganisms as well as semi-synthetic variants produced in the laboratory. On average, we found that resistance genes found in permafrost bacteria conferred lower levels of resistance against clinically relevant antibiotics than resistance genes sampled from the active layer. Our results demonstrate that antibiotic resistance genes were functionally diverse prior to the anthropogenic use of antibiotics, contributing to the evolution of natural reservoirs of resistance genes.

    The consequences of the Neolithic transition in Europe—one of the most important cultural changes in human prehistory—is a subject of great interest. However, its effect on prehistoric and modern-day people in Iberia, the westernmost frontier of the European continent, remains unresolved. We present, to our knowledge, the first genome-wide sequence data from eight human remains, dated to between 5,500 and 3,500 years before present, excavated in the El Portalón cave at Sierra de Atapuerca, Spain. We show that these individuals emerged from the same ancestral gene pool as early farmers in other parts of Europe, suggesting that migration was the dominant mode of transferring farming practices throughout western Eurasia. In contrast to central and northern early European farmers, the Chalcolithic El Portalón individuals additionally mixed with local southwestern hunter–gatherers. The proportion of hunter–gatherer-related admixture into early farmers also increased over the course of two millennia. The Chalcolithic El Portalón individuals showed greatest genetic affinity to modern-day Basques, who have long been considered linguistic and genetic isolates linked to the Mesolithic whereas all other European early farmers show greater genetic similarity to modern-day Sardinians. These genetic links suggest that Basques and their language may be linked with the spread of agriculture during the Neolithic. Furthermore, all modern-day Iberian groups except the Basques display distinct admixture with Caucasus/Central Asian and North African groups, possibly related to historical migration events. The El Portalón genomes uncover important pieces of the demographic history of Iberia and Europe and reveal how prehistoric groups relate to modern-day people. PMID:26351665

  6. Francis Bacon's natural history and the Senecan natural histories of early modern Europe.

    At various stages in his career, Francis Bacon claimed to have reformed and changed traditional natural history in such a way that his new "natural and experimental history" was unlike any of its ancient or humanist predecessors. Surprisingly, such claims have gone largely unquestioned in Baconian scholarship. Contextual readings of Bacon's natural history have compared it, so far, only with Plinian or humanist natural history. This paper investigates a different form of natural history, very popular among Bacon's contemporaries, but yet unexplored by contemporary students of Bacon's works. I have provisionally called this form of natural history'Senecan' natural history, partly because it took shape in the Neo-Stoic revival of the sixteenth-century, partly because it originates in a particular cosmographical reading of Seneca's Naturales quaestiones. I discuss in this paper two examples of Senecan natural history: the encyclopedic and cosmographical projects of Pierre de la Primaudaye (1546-1619) and Samuel Purchas (1577-1626). I highlight a number of similarities between these two projects and Francis Bacon's natural history, and argue that Senecan natural history forms an important aspect in the historical and philosophical background that needs to be taken into consideration if we want to understand the extent to which Bacon's project to reform natural history can be said to be new.

  7. Hysteria in ancient civilisations: A neurological review: Possible significance for the modern disorder.

    2018-05-15

    The word hysteria originated in the Corpus Hippocraticum (c420 BCE) as a natural explanation for a variety of diseases in women linked in the Greco-Roman mind to an animate or inanimate womb, but which in the last five centuries has evolved to describe an elusive disorder of brain ± mind in men and women, currently referred to by neurologists as "functional neurological disorder". The Babylonians, Assyrians and Egyptians had no knowledge of brain or psychological function. Babylonian and Assyrian descriptions of disease and behaviour include only rare examples suggestive of modern hysteria. An earlier suggestion that the Greek concept of hysteria was transmitted from Egypt is not supported by recent evidence. The Greco-Roman civilisations had some knowledge of neuroanatomy, but little of nervous system function, conceived in terms of humors. The examples cited here suggestive of modern hysteria are relatively infrequent and fragmentary. The most plausible are attempts to separate the "sacred disease" from other causes of loss of consciousness. The great achievement of Greco-Roman medicine was in introducing natural causation, including causation linked to the womb, rather than gods or evil spirits. Nevertheless medicine, magic and religion have remained intertwined to varying degrees in all cultures up to the present time, despite the growth of modern scientific medicine. The study of hysteria in ancient civilisations adds interesting insight into the evolution of thinking about brain, psyche, mind and self. Babylonian and Egyptian medical and behavioural descriptions are based on observation. Greek and Roman accounts include some subjective aspects, probably linked to early attempts to understand identity, the psyche, intellectual and emotional functions. The great philosophical debate whether the latter resided in the head/brain (Plato) or the heart (Aristotle) has only been settled in the last few centuries, during which hysteria also became linked to

    Atherosclerosis is thought to be a disease of modern human beings and related to contemporary lifestyles. However, its prevalence before the modern era is unknown. We aimed to evaluate preindustrial populations for atherosclerosis. We obtained whole body CT scans of 137 mummies from four different geographical regions or populations spanning more than 4000 years. Individuals from ancient Egypt, ancient Peru, the Ancestral Puebloans of southwest America, and the Unangan of the Aleutian Islands were imaged. Atherosclerosis was regarded as definite if a calcified plaque was seen in the wall of an artery and probable if calcifications were seen along the expected course of an artery. Probable or definite atherosclerosis was noted in 47 (34%) of 137 mummies and in all four geographical populations: 29 (38%) of 76 ancient Egyptians, 13 (25%) of 51 ancient Peruvians, two (40%) of five Ancestral Puebloans, and three (60%) of five Unangan hunter gatherers (p=NS). Atherosclerosis was present in the aorta in 28 (20%) mummies, iliac or femoral arteries in 25 (18%), popliteal or tibial arteries in 25 (18%), carotid arteries in 17 (12%), and coronary arteries in six (4%). Of the five vascular beds examined, atherosclerosis was present in one to two beds in 34 (25%) mummies, in three to four beds in 11 (8%), and in all five vascular beds in two (1%). Age at time of death was positively correlated with atherosclerosis (mean age at death was 43 [SD 10] years for mummies with atherosclerosis vs 32 [15] years for those without; phuman beings raises the possibility of a more basic predisposition to the disease.

  9. ACEH IN HISTORY: Preserving Traditions and Embracing Modernity

    2013-12-01

    Full Text Available This paper attempts to critically discuss on how the Acehnese in history, while trying to embrace the modern world, have made every effort at preserving their traditions. As an ethnic group which has a glorious past, Aceh has strongly been connected to “identity”; and this is expressed in various means, including “social memory.” For this very reason, “traditions”, including those of the past, are explored and preserved. Yet, the challenges of modernity are also apparent. It is in this context that the Acehnese are trapped at the crossroad. On the one hand, they tend to preserve their traditions, yet, on the other, they need to embrace modern lives. The Acehnese seem to have encountered considerable obstacles on this issue, for they tend to focus more on historical “romanticism” (nostalgia rather than historical “awareness” (consciousness. Eventually, the “spirit” of the past cannot be brought into light.

    2016-01-01

    Alexus McLeod explores every aspect of the lesser-known history of astronomy in the Americas (Mesoamerica and North America), China and India, each through the frame of a particular astronomical phenomena. Part One considers the development of astronomy in the Americas as a response, in part, to the Supernova of 1054, which may have led to a cultural renaissance in astronomy. He then goes on to explore the contemporary understanding of supernovae, contrasting it with that of the ancient Americas.  Part Two is framed through the appearances of great comets, which had major divinatory significance in early China. The author discusses the advancement of observational astronomy in China, its influence on politics and its role in the survival or failure of empires.  Furthermore, the contemporary understanding of comets is also discussed for comparison.  Part Three, on India, considers the magnificent observatories of the Rajput king Jai Singh II, and the question of their purpose. The origins of Indian ast...

    Nicolaides, Demetris

    2014-01-01

    The birth of science in ancient Greece had a historical impact that is still being felt today. Physicist Demetris Nicolaides examines the epochal shift in thinking that led pre-Socratic philosophers of the sixth and fifth centuries BCE to abandon the prevailing mythologies of the age and, for the first time, to analyze the natural world in terms of impersonal, rationally understood principles. He argues not only that their conceptual breakthroughs anticipated much of later science but that scientists of the twenty-first century are still grappling with the fundamental problems raised twenty-five hundred years ago. Looking at the vast sweep of human history, the author delves into the factors that led to the birth of science: urbanization, the role of religion, and in Greece a progressive intellectual curiosity that was unafraid to question tradition. Why did the first scientific approach to understanding the world take place in Greece? The author makes a convincing case that, aside from factors of geography...

The main argument focuses on the fact that the awqaf system has provided throughout Islamic history all the essential services at no cost to the state. Thus, a successful modernisation of the system implies a significant cut in government expenditure and all the associated benefits; including downsizing the state sector and a reduction and even an eventual elimination of riba.

    Twentieth-century China has been caught between a desire to increase its wealth and power in line with other advanced nations, which, by implication, means copying their institutions, practices and values, whilst simultaneously seeking to preserve China's independence and historically formed identity. Over time, Chinese philosophers, writers, artists and politicians have all sought to reconcile these goals and this book shows how this search for a Chinese way penetrated even the most central, least contested area of modernity: science.Reviving Ancient Chinese Mathematics is a study of the life

  14. Assembling the dodo in early modern natural history.

    Science.gov (United States)

    Lawrence, Natalie

    2015-09-01

    This paper explores the assimilation of the flightless dodo into early modern natural history. The dodo was first described by Dutch sailors landing on Mauritius in 1598, and became extinct in the 1680s or 1690s. Despite this brief period of encounter, the bird was a popular subject in natural-history works and a range of other genres. The dodo will be used here as a counterexample to the historical narratives of taxonomic crisis and abrupt shifts in natural history caused by exotic creatures coming to Europe. Though this bird had a bizarre form, early modern naturalists integrated the dodo and other flightless birds through several levels of conceptual categorization, including the geographical, morphological and symbolic. Naturalists such as Charles L'Ecluse produced a set of typical descriptive tropes that helped make up the European dodo. These long-lived images were used for a variety of symbolic purposes, demonstrated by the depiction of the Dutch East India enterprise in Willem Piso's 1658 publication. The case of the dodo shows that, far from there being a dramatic shift away from emblematics in the seventeenth century, the implicit symbolic roles attributed to exotic beasts by naturalists constructing them from scant information and specimens remained integral to natural history.

  16. Astronomical References in Chaucer: What Can Modern Students Learn from Studying Ancient Texts?

    Directory of Open Access Journals (Sweden)

    Victor Kennedy

    2005-06-01

    Full Text Available One of the problems in the field of English literature studies is that, with compartmentalization and specialization, it becomes introspective to the point where it devolves into the study of metafiction and metacriticism. At its heart, however, literature has to be about something: Thackeray claimed its subject is human nature, but human nature is based in the interface between human and nature. This paper explores some of the problems in the interface between human knowledge, institutions, and nature, and will offer an example of cross-disciplinary, historical study to illustrate a well-known but, to most modern readers, impenetrable medieval text, Chaucer’s Treatise on the Astrolabe. It ends with three recommendations: look to history, cross boundaries between academic fields, and use practical, as well as theoretical, teaching methods.

As a discipline, History holds a specific place among disciplines of a humanitarian cycle of educational programs of higher education institutions regardless of university specialities. History plays an important role in the course of formation of a citizen and development of critical thinking of a personality as an element of a common culture. However, new federal standards require a drastic reduction of the classroom hours for studying a History course by students of non-humanitarian specialties, and, at the same time, enhancement of the contents of a discipline (its reorientation from History of Russia towards World History. Therefore, History programmes and courses demand up-to-date approaches, methods and didactic means to provide formation of holistic worldview of future experts.The aim of the article is to consider the features of innovative methods application in teaching history in high school taking into consideration modernization processes.Methodology and research methods. The research undertaken is based on activity and competence-based approaches. The methods of analysis and synthesis of the academic literature on the research topic were used; the methods of reflection and generalization of teaching activities of the Department of Humanitarian Disciplines of theKazanNationalResearchTechnologicalUniversity were applied as well.Results and scientific novelty. A modern view on historical education has been proposed as means of students’ systems thinking formation, designing the ideas about the world historical process among students, the mission ofRussia in this process, and evolution ofRussia as a part of the modern civilization. It is stated that History university course is designed not only to give the students strong subject knowledge, but also to create axiological orientations and abilities on the basis of the analysis of historical collisions, objective and subjective factors of society development.

    Full Text Available Over the past decades, Chinese herbal medicines (CHM have been extensively and intensively studied through from both clinical and experimental perspectives and CHM have been proved to be effective in the treatment of diabetes mellitus (DM. This study, by searching ancient records and modern research papers, reviewed CHM in terms of their clinical application and principal mechanism in the treatment of DM. We summarized the use of CHM mentioned in 54 famous ancient materia medica monographs and searched papers on the hypoglycemic effect of several representative CHM. Main mechanisms and limitations of CHM and further research direction for DM were discussed. On the basis of the study, we were led to conclude that TCM, as a main form of complementary and alternative medicine (CAM, was well recorded in ancient literatures and has less adverse effects as shown by modern studies. The mechanisms of CHM treatment of DM are complex, multilink, and multitarget, so we should find main hypoglycemic mechanism through doing research on CHM monomer active constituents. Many CHM monomer constituents possess noteworthy hypoglycemic effects. Therefore, developing a novel natural product for DM and its complications is of much significance. It is strongly significant to pay close attention to CHM for treatment of DM and its complications.

    Polar bears (Ursus maritimus) are among those species most susceptible to the rapidly changing arctic climate, and their survival is of global concern. Despite this, little is known about polar bear species history. Future conservation strategies would significantly benefit from an understanding of basic evolutionary information, such as the timing and conditions of their initial divergence from brown bears (U. arctos) or their response to previous environmental change. We used a spatially explicit phylogeographic model to estimate the dynamics of 242 brown bear and polar bear matrilines sampled throughout the last 120,000 years and across their present and past geographic ranges. Our results show that the present distribution of these matrilines was shaped by a combination of regional stability and rapid, long-distance dispersal from ice-age refugia. In addition, hybridization between polar bears and brown bears may have occurred multiple times throughout the Late Pleistocene. The reconstructed matrilineal history of brown and polar bears has two striking features. First, it is punctuated by dramatic and discrete climate-driven dispersal events. Second, opportunistic mating between these two species as their ranges overlapped has left a strong genetic imprint. In particular, a likely genetic exchange with extinct Irish brown bears forms the origin of the modern polar bear matriline. This suggests that interspecific hybridization not only may be more common than previously considered but may be a mechanism by which species deal with marginal habitats during periods of environmental deterioration.

  3. Narrative and Cultural History in the Hippocratic Treatise On Ancient Medicine

    Directory of Open Access Journals (Sweden)

    Marco Romani Mistretta

    2016-12-01

    Full Text Available This paper focuses on the ‘history of medicine’ outlined by the author of the Hippocratic treatise On Ancient Medicine, in order to reflect on the relationship between medicine and narrative in Classical Greece. At the outset of the work, the author provides an account of the beginnings of his discipline, conceiving of medicine’s history as a continuum of research and findings that unravel the nature of the human body and the cause of diseases. As this paper shows, the physician-narrator assigns to his craft a crucial role in fostering the birth and progress of human civilization. The rhetorical goals of the historical account are, as I argue, attained through a subtle narrative strategy. In fact, the narrator locates the origins of medicine within a teleological framework, marked by strong emphasis on the heuristic method that characterizes the past, the present, and the future of medical knowledge at once.

    1987-01-01

    Linked scanning of a tandem sector mass spectrometer has been used to identify abundant, first field free region (FFR1) unimolecular fragmentations in branched and isoprenoid hydrocarbons. The most intense, structure-specific reactions were selected to establish multiple reaction monitoring (MRM) parameters for GC/MS analysis. This methodology has been used to study the identify of co-eluting and closely eluting hydrocarbon biomarkers from modern and ancient sediments and from extant microorganisms. Some sediments of Cambrian and Proterozoic age have been found to contain suites of monomethylalkanes with all possible isomers present and with little apparent preference for the site of branching.

    Ancient buried terrestrial landscapes contain records of vertical motions which can be used to probe histories of geodynamical processes. In the North Atlantic Ocean, sedimentary basins contain excellent evidence that the continental shelf experienced staged subaerial exposure. For example, now buried landscapes were uplifted, rapidly eroded, and drowned close to the Paleocene-Eocene boundary. We use commercial wells and three-dimensional seismic data to reconstruct a 57-55 Ma landscape now buried 1.5 km beneath the seabed in the Bressay area of the northern North Sea. Geochemical analyses of organic matter from core samples intersecting the erosional landscape indicate the presence of angiosperm (flowering plant) debris. Combined with the presence of coarse clastic material, mapped beach ridges, and dendritic drainage patterns, these observations indicate that this landscape was of terrestrial origin. Longitudinal profiles of ancient rivers were extracted and inverted for an uplift rate history. The best-fitting uplift rate history has three phases and total cumulative uplift of 350 m. Biostratigraphic data from surrounding marine stratigraphy indicate that this landscape formed within 1-1.5 Ma. This uplift history is similar to that of a slightly older buried landscape in the Faeroe-Shetland basin 400 km to the west. These records of vertical motion can explained by pulses of anomalously hot asthenosphere spreading out from the incipient Icelandic plume. Using simple isostatic calculations we estimate that the maximum thermal anomaly beneath Bressay was 50˚. Our observations suggest that a thermal anomaly departed the Icelandic plume as early as 58.5 Ma and had highest average temperatures at 55.6 Ma.

    Full Text Available Nature, especially the marine environment, provides the most effective drugs used in human therapy. Among the metazoans, the marine sponges (phylum Porifera, which are sessile filter feeders, produce the most potent and highly selective bioactive secondary metabolites. These animals (or their associated symbiotic microorganisms synthesize secondary metabolites whose activity and selectivity has developed during their long evolutionary history (evochemistry. The exploitation of these resources has become possible due to the progress in molecular and cell biology. BIOTECmarin, the German Center of Excellence follows this rationale. In the past, these animals have been successfully and extensively utilized to isolate bioactive compounds and biomaterials for human benefit. Pharmaceuticals prepared from marine animals, primarily sponges, have been applied since ancient times (Hippocrates, Aristotle and later Plinius. It has been reported that extracts and/or components from sponges can be used for the treatment of specific diseases. For a systematic and applied-oriented exploitation, the successful development of effective compounds largely depends on quality of the institutional infrastructure of marine stations and more so on the biodiversity. The Center for Marine Research in Rovinj (Croatia fulfils these prerequisites. Founded in 1891, this institute has to its credit major discoveries related to exploitation of secondary metabolites/biomaterials from sponges for therapeutical application and to obtain biomaterials for general wellbeing.This is the first part of a review focusing on biomedical prospecting. Here, we have mainly described the historic background. The details of techniques, substances, approaches and outlooks will be discussed in the second part.

    Saber-toothed cats (Machairodontinae) are among the most widely recognized representatives of the now largely extinct Pleistocene megafauna. However, many aspects of their ecology, evolution, and extinction remain uncertain. Although ancient-DNA studies have led to huge advances in our knowledge of these aspects of many other megafauna species (e.g., mammoths and cave bears), relatively few ancient-DNA studies have focused on saber-toothed cats [1-3], and they have been restricted to short fragments of mitochondrial DNA. Here we investigate the evolutionary history of two lineages of saber-toothed cats (Smilodon and Homotherium) in relation to living carnivores and find that the Machairodontinae form a well-supported clade that is distinct from all living felids. We present partial mitochondrial genomes from one S. populator sample and three Homotherium sp. samples, including the only Late Pleistocene Homotherium sample from Eurasia [4]. We confirm the identification of the unique Late Pleistocene European fossil through ancient-DNA analyses, thus strengthening the evidence that Homotherium occurred in Europe over 200,000 years later than previously believed. This in turn forces a re-evaluation of its demography and extinction dynamics. Within the Machairodontinae, we find a deep divergence between Smilodon and Homotherium (∼18 million years) but limited diversity between the American and European Homotherium specimens. The genetic data support the hypothesis that all Late Pleistocene (or post-Villafrancian) Homotherium should be considered a single species, H. latidens, which was previously proposed based on morphological data [5, 6].

    These essays collectively present new perspectives on the history of modem science in China since 1900. Fa-ti Fan describes how science under the Republic of China after 1911 exhibited a complex local and international character that straddled both imperialism and colonialism. Danian Hu focuses on the fate of relativity in the physics community in China after 1917. Zuoyue Wang hopes that a less nationalist political atmosphere in China will stimulate more transnational studies of modern science, which will in turn reveal the underlying commonalities in different national contexts. Sigrid Schmalzer compares the socialist and the capitalist contexts for science in China and reopens the sensitive question of the "mass line" during the Cultural Revolution. Grace Shen describes the tensions early Chinese scientists felt when choosing between foreign models for modem geology and their own professional identities in China. Taken together, these accounts present us with a comparative history of modern science in China that is both globally and locally informed.

    Full Text Available Statement of the problem. Despite the attempts of historians to objectively present the events of the prehistory and history of the war, the opening of new archives and the desire to get rid of ideological stereotypes, are driving the need to once again explore the role of Ukraine in world war II to prevent its recurrence. On the other hand, the deep understanding of the history of the previous generations will provide an opportunity to properly understand the events of today. The analysis of the research. During the years of independence in the national historiography it was a new understanding of the conceptual foundations of the study of war. Over the past decade it was written a large number of scientific studies in which the main direction of new concepts there was an increased attention to the person, separate social groups and society as a whole in situations of conflict and crises. The article aims to analyze the role and place of Ukraine in the events of the Second world war; identify "Ukrainian dimension" of war and its implications for the modern generation, especially the youth. Conclusion. The effects of war for decades identified the complex and contradictory political, economic and social processes in Ukrainian society, affected the moral and psychological qualities of post-war generations. The memory of war – spiritual-historical heritage of our nation, which lays the foundations for self-sufficiency and identity and integrates it seamlessly into a civilizational flow. The modern level of researches of the events of world war II pays special attention to humanitarian problems of the war. For the youth of Ukraine it is important to join the European perception of the war as tragedy, to understand the responsibility for the memory of the past, because it's a chance for the future.

  12. Toward a new history and geography of human genes informed by ancient DNA.

    Genetic information contains a record of the history of our species, and technological advances have transformed our ability to access this record. Many studies have used genome-wide data from populations today to learn about the peopling of the globe and subsequent adaptation to local conditions. Implicit in this research is the assumption that the geographic locations of people today are informative about the geographic locations of their ancestors in the distant past. However, it is now clear that long-range migration, admixture, and population replacement subsequent to the initial out-of-Africa expansion have altered the genetic structure of most of the world's human populations. In light of this we argue that it is time to critically reevaluate current models of the peopling of the globe, as well as the importance of natural selection in determining the geographic distribution of phenotypes. We specifically highlight the transformative potential of ancient DNA. By accessing the genetic make-up of populations living at archaeologically known times and places, ancient DNA makes it possible to directly track migrations and responses to natural selection.

  13. Ancient mantle in a modern arc: osmium isotopes in izu-bonin-mariana forearc peridotites

    Parkinson; Hawkesworth; Cohen

    1998-09-25

    Mantle peridotites drilled from the Izu-Bonin-Mariana forearc have unradiogenic 187Os/188Os ratios (0.1193 to 0.1273), which give Proterozoic model ages of 820 to 1230 million years ago. If these peridotites are residues from magmatism during the initiation of subduction 40 to 48 million years ago, then the mantle that melted was much more depleted in incompatible elements than the source of mid-ocean ridge basalts (MORB). This result indicates that osmium isotopes record information about ancient melting events in the convecting upper mantle not recorded by incompatible lithophile isotope tracers. Subduction zones may be a graveyard for ancient depleted mantle material, and portions of the convecting upper mantle may be less radiogenic in osmium isotopes than previously recognized.

    Iberian horses supports this suggestion. To test this hypothesis, we analysed mitochondrial DNA from 22 ancient Iberian horse remains belonging to the Neolithic, the Bronze Age and the Middle Ages, against previously published sequences. Only the medieval Iberian sequence appeared in the D1 group...... wild mares during an early Iberian domestication or restocking event, whereas the D1 group probably was introduced into Iberia in later historical times....

    Southern Africa is consistently placed as a potential region for the evolution of Homo sapiens We present genome sequences, up to 13x coverage, from seven ancient individuals from KwaZulu-Natal, South Africa. The remains of three Stone Age hunter-gatherers (about 2000 years old) were genetically similar to current-day southern San groups, and those of four Iron Age farmers (300 to 500 years old) were genetically similar to present-day Bantu-language speakers. We estimate that all modern-day Khoe-San groups have been influenced by 9 to 30% genetic admixture from East Africans/Eurasians. Using traditional and new approaches, we estimate the first modern human population divergence time to between 350,000 and 260,000 years ago. This estimate increases the deepest divergence among modern humans, coinciding with anatomical developments of archaic humans into modern humans, as represented in the local fossil record.

    Full Text Available http://dx.doi.org/10.5007/1808-1711.2016v20n1p117 As part of an ongoing study of causal models in the history of science, a counterfactual scenario in the history of modern astronomy is explored with the aid of computer simulations. After the definition of “linking advance”, a possible world involving technological antecedence is described, branching out in 1510, in which the telescope is invented 70 years before its actual construction, at the time in which Fracastoro actually built the first prototelescope. By using the principle of the closest possible world (PCP, we estimate that in this scenario the discovery of the elliptical orbit of Mars would by anticipated by only 28 years. The second part of the paper involves an estimate of the probability of the previous scenario, guided by the principle that the actual world is the mean (PAM and using computer simulations to create possible worlds in which the time spans between advances is varied according to a gamma distribution function. Taking into account the importance of the use of the diaphragm for the invention of the telescope, the probability that the telescope were built by 1538 for a branching time at 1510 is found to be smaller than 1%. The work shows that one of the important features of computational simulations in philosophy of science is to serve as a consistency check for the intuitions and speculations of the philosopher.

  17. Incorporation of Trace Elements in Ancient and Modern Human Bone: An X-Ray Absorption Spectroscopy Study

    Science.gov (United States)

    Pingitore, N. E.; Cruz-Jimenez, G.; Price, T. D.

    2001-12-01

    X-ray absorption spectroscopy (XAS) affords the opportunity to probe the atomic environment of trace elements in human bone. We are using XAS to investigate the mode(s) of incorporation of Sr, Zn, Pb, and Ba in both modern and ancient (and thus possibly altered) human and animal bone. Because burial and diagenesis may add trace elements to bone, we performed XAS analysis on samples of pristine contemporary and ancient, buried human and animal bone. We assume that deposition of these elements during burial occurs by processes distinct from those in vivo, and this will be reflected in their atomic environments. Archaeologists measure strontium in human and animal bone as a guide to diet. Carnivores show lower Sr/Ca ratios than their herbivore prey due to discrimination against Sr relative to Ca up the food chain. In an initial sample suite no difference was observed between modern and buried bone. Analysis of additional buried samples, using a more sensitive detector, revealed significant differences in the distance to the second and third neighbors of the Sr in some of the buried samples. Distances to the first neighbor, oxygen, were similar in all samples. Zinc is also used in paleo-diet studies. Initial x-ray absorption spectroscopy of a limited suite of bones did not reveal any differences between modern and buried samples. This may reflect the limited number of samples examined or the low levels of Zn in typical aqueous solutions in soils. Signals from barium and lead were too low to record useful XAS spectra. Additional samples will be studied for Zn, Ba, and Pb. We conducted our XAS experiments on beam lines 4-1 and 4-3 at the Stanford Synchrotron Radiation Laboratory. Data were collected in the fluorescence mode, using a Lytle detector and appropriate filter, and a solid state, 13-element Ge-detector.

  18. Ancient mitochondrial DNA and the genetic history of Eurasian beaver (Castor fiber) in Europe.

    After centuries of human hunting, the Eurasian beaver Castor fiber had disappeared from most of its original range by the end of the 19th century. The surviving relict populations are characterized by both low genetic diversity and strong phylogeographical structure. However, it remains unclear whether these attributes are the result of a human-induced, late Holocene bottleneck or already existed prior to this reduction in range. To investigate genetic diversity in Eurasian beaver populations during the Holocene, we obtained mitochondrial control region DNA sequences from 48 ancient beaver samples and added 152 modern sequences from GenBank. Phylogeographical analyses of the data indicate a differentiation of European beaver populations into three mitochondrial clades. The two main clades occur in western and eastern Europe, respectively, with an early Holocene contact zone in eastern Europe near a present-day contact zone. A divergent and previously unknown clade of beavers from the Danube Basin survived until at least 6000 years ago, but went extinct during the transition to modern times. Finally, we identify a recent decline in effective population size of Eurasian beavers, with a stronger bottleneck signal in the western than in the eastern clade. Our results suggest that the low genetic diversity and the strong phylogeographical structure in recent beavers are artefacts of human hunting-associated population reductions. While beaver populations have been growing rapidly since the late 19th century, genetic diversity within modern beaver populations remains considerably reduced compared to what was present prior to the period of human hunting and habitat reduction.

    Appropriate dose guarantees Chinese herb's safety and effectiveness. There are adult dose criteria for Chinese herbs in decoction in the Pharmacopoeia of the People's Republic of China (2010 Edition) at present. But Chinese herbs have been frequently used in much higher doses than the dose criteria. This study has been conducted to test the dependability of the dose criteria. Twenty Chinese herbs were selected as representatives and their adult doses in decoction in Bei Ji Qian Jin Yao Fang, a famous ancient literature, have been reviewed and compared with those in the Pharmacopoeia of the People's Republic of China (2010 Edition). The adult dose criteria for all these 20 Chinese herbs in the Pharmacopoeia of the People's Republic of China (2010 Edition) haven't covered those in Bei Ji Qian Jin Yao Fang. Furthermore, maximal adult doses in the dose criteria are much lower than those in Bei Ji Qian Jin Yao Fang. The dose criteria in the Pharmacopoeia of the People's Republic of China (2010 Edition) are not comprehensive enough. Studying ancient literatures is an effective method to gain precious Chinese herbs' dose data and helps for new dose criteria's establishment in the future.

    This nomogram was designed to aid in interpreting the causes of mass movement in modern and ancient settings, to provide a basis for evaluating and predicting slope stability under given conditions and to further the understanding of the relationships among the several key factors that control slope stability. Design of the nomogram is based on effective stress and combines consolidation theory as applicable to depositional environments with the infinite-slope model of slope-stability analysis. If infinite-slope conditions are assumed to exist, the effective overburden stress can be used to derive a factor of safety against static slope failure by using the angle of internal friction and the slope angle. -from Authors

  3. From ancient to avant-garde: a review of traditional and modern multimodal approaches to surgical anatomy education.

    Science.gov (United States)

    2018-03-01

    The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education. However, novel methods and technological advancements continually give way to adjuncts such as cadaveric surgery, three-dimensional printing, virtual simulation and live surgical streaming, which have demonstrated significant efficacy alone or alongside dissection. Therefore, although divergent paradigms of 'new versus old' approaches have engulfed and divided the community, educators should seek to integrate the ancient and avant-garde to comprehensively satisfy all of the modern anatomy learner's educational needs. © 2017 Royal Australasian College of Surgeons.

    Ancient blue oak trees are still widespread across the foothills of the Coast Ranges, Cascades, and Sierra Nevada in California. The most extensive tracts of intact old-growth blue oak woodland appear to survive on rugged and remote terrain in the south Coast Ranges and on the foothills west and southwest of Mt. Lassen. In our sampling of old-growth stands, most blue oak appear to have recruited to the canopy in the mid- to late-19th century. The oldest living blue oak tree sampled was over 459-years old and several dead blue oak logs had over 500 annual rings. Precipitation sensitive tree-ring chronologies up to 700-years long have been developed from old blue oak trees and logs. Annual ring-width chronologies of blue oak are strongly correlated with cool season precipitation totals, streamflow in the major rivers of California, and the estuarine water quality of San Francisco Bay. A new network of 36 blue oak chronologies records spatial anomalies in growth that arise from latitudinal changes in the mean storm track and location of landfalling atmospheric rivers. These long, climate-sensitive blue oak chronologies have been used to reconstruct hydroclimatic history in California and will help to better understand and manage water resources. The environmental history embedded in blue oak growth chronologies may help justify efforts to conserve these authentic old-growth native woodlands.

  5. Molecular fossils in modern genomes provide physiological and geochemical insights to the ancient earth (Invited)

    Dupont, C.; Caetano-Anolles, G.

    2010-12-01

    The genomes of extant organisms are ultimately derived from ancient life, thus theoretically contain insight to ancient physiology, ecology, and environments. In particular, metalloenzymes may be particularly insightful. The fundamental chemistry of trace elements dictates the molecular speciation and reactivity both within cells and the environment at large. Using protein structure and comparative genomics, we elucidate several major influences this chemistry has had upon biology. All of life exhibits the same proteome size-dependent scaling for the number of metal-binding proteins within a proteome. This fundamental evolutionary constant shows that the selection of one element occurs at the exclusion of another, with the eschewal of Fe for Zn and Ca being a defining feature of eukaryotic pro- teomes. Early life lacked both the structures required to control intracellular metal concentrations and the metal-binding proteins that catalyze electron transport and redox transformations. The development of protein structures for metal homeostasis coincided with the emergence of metal-specific structures, which predomi- nantly bound metals abundant in the Archean ocean. Potentially, this promoted the diversification of emerging lineages of Archaea and Bacteria through the establishment of biogeochemical cycles. In contrast, structures binding Cu and Zn evolved much later, pro- viding further evidence that environmental availability influenced the selection of the elements. The late evolving Zn-binding proteins are fundamental to eukaryotic cellular biology, and Zn bioavailabil- ity may have been a limiting factor in eukaryotic evolution. The results presented here provide an evolutionary timeline based on genomic characteristics, and key hypotheses can be tested by alternative geochemical methods.

    Flaser and wavy bedding are sedimentary structures characterized by alternating rippled sand and mud layers. These structures often are considered to form mostly in tidally influenced environments; published examples from fluvial environments are rare. Flaser and wavy bedding were found in two ephemeral stream deposits: the Jurassic Kayenta Formation and the modern wash in Seven Mile Canyon, both located in southeastern Utah, USA. These examples demonstrate that flaser bedding can form and be preserved in ephemeral streams.

  9. Docosahexaenoic Acid (DHA: An Ancient Nutrient for the Modern Human Brain

    2011-05-01

    Full Text Available Modern humans have evolved with a staple source of preformed docosahexaenoic acid (DHA in the diet. An important turning point in human evolution was the discovery of high-quality, easily digested nutrients from coastal seafood and inland freshwater sources. Multi-generational exploitation of seafood by shore-based dwellers coincided with the rapid expansion of grey matter in the cerebral cortex, which characterizes the modern human brain. The DHA molecule has unique structural properties that appear to provide optimal conditions for a wide range of cell membrane functions. This has particular implications for grey matter, which is membrane-rich tissue. An important metabolic role for DHA has recently been identified as the precursor for resolvins and protectins. The rudimentary source of DHA is marine algae; therefore it is found concentrated in fish and marine oils. Unlike the photosynthetic cells in algae and higher plants, mammalian cells lack the specific enzymes required for the de novo synthesis of alpha-linolenic acid (ALA, the precursor for all omega-3 fatty acid syntheses. Endogenous synthesis of DHA from ALA in humans is much lower and more limited than previously assumed. The excessive consumption of omega-6 fatty acids in the modern Western diet further displaces DHA from membrane phospholipids. An emerging body of research is exploring a unique role for DHA in neurodevelopment and the prevention of neuropsychiatric and neurodegenerative disorders. DHA is increasingly being added back into the food supply as fish oil or algal oil supplementation.

    The recent expansion of next-generation sequencing has significantly improved biological research. Nevertheless, deep exploration of genomes or metagenomic samples remains difficult because of the sequencing depth and the associated costs required. Therefore, different partitioning strategies have been developed to sequence informative subsets of studied genomes. Among these strategies, hybridization capture has proven to be an innovative and efficient tool for targeting and enriching specific biomarkers in complex DNA mixtures. It has been successfully applied in numerous areas of biology, such as exome resequencing for the identification of mutations underlying Mendelian or complex diseases and cancers, and its usefulness has been demonstrated in the agronomic field through the linking of genetic variants to agricultural phenotypic traits of interest. Moreover, hybridization capture has provided access to underexplored, but relevant fractions of genomes through its ability to enrich defined targets and their flanking regions. Finally, on the basis of restricted genomic information, this method has also allowed the expansion of knowledge of nonreference species and ancient genomes and provided a better understanding of metagenomic samples. In this review, we present the major advances and discoveries permitted by hybridization capture and highlight the potency of this approach in all areas of biology. © The Author(s) 2016.

    The present study aims to evaluate the preservation of the microstructure of skeletal remains collected from four different known burial sites (archaeological and contemporary). Histological analysis on undecalcified and decalcified thin sections was performed in order to assess which of the two techniques is more affected by taphonomic insults. A histological analysis was performed on both undecalcified and decalcified thin sections of 40 long bones and the degree of diagenetic change was evaluated using transmitted and polarized light microscopy according to the Oxford Histological Index (OHI). In order to test the optical behavior of bone tissue, thin sections were observed by polarized light microscopy and the intensity of birefringence was evaluated. The more ancient samples are generally characterized by a low OHI (0-1) with extensive microscopic focal destruction; recent samples exhibited a better preservation of bone micromorphology. When comparing undecalcified to decalcified thin sections, the latter showed an amelioration in the conservation of microscopic structure. As regards the birefringence, it was very low in all the undecalcified thin sections, whereas decalcification process seems to improve its visibility. The preservation of the bone microscopic structure appears to be influenced not only by age, but also by the burial context. Undecalcified bones appear to be more affected by taphonomical alterations, probably because of the thickness of the thin sections; on the contrary, decalcified thin sections proved to be able to tackle this issue allowing a better reading of the bone tissue. © 2017 Wiley Periodicals, Inc.

    We report new archeointensity results from Iranian and Syrian archeological excavations dated from the second millennium BC. These high-temperature magnetization data were obtained using a laboratory-built triaxial vibrating sample magnetometer. Together with our previously published archeointensity results from Mesopotamia, we constructed a rather detailed geomagnetic field intensity variation curve for this region from 3000 BC to 0 BC. Four potential geomagnetic events ("archeomagnetic jerks"), marked by strong intensity increases, are observed and appear to be synchronous with cooling episodes in the North Atlantic. This temporal coincidence strengthens the recent suggestion that the geomagnetic field influences climate change over multi-decadal time scales, possibly through the modulation of cosmic ray flux interacting with the atmosphere. Moreover, the cooling periods in the North Atlantic coincide with episodes of enhanced aridity in the Middle East, when abrupt societal changes occurred in the eastern Mediterranean and Mesopotamia. Although the coincidences discussed in this paper must be considered with caution, they lead to the possibility that the geomagnetic field impacted the history of ancient civilizations through climatically driven environmental changes, triggering economic, social and political instability.

    Full Text Available Goethe’s rejection of Newton’s theory of colors is an interesting example of the vulnerability of the human mind—however brilliant it might be—to fanaticism. After an analysis of Goethe’s persistent fascination with magic and occultism, of his education, existential experiences, influences, and idiosyncrasies, the authors propose an original interpretation of his anti-Newtonian position. The relevance of Goethe’s Farbenlehre to physics and physiology, from the perspective of modern science, is discussed in detail.

    2012-01-01

    About 1700 years BC, the prophet Zoroaster declared equal right for women and men to choose their "own ways." There is much evidence that ancient Persians believed in the equal contribution of women and men toward producing a child, and all its hereditary characteristics.Even more surprising are the phrases in Vandidad book, which were gathered by Mobedans in the Mad dynasty about egg extraction (gametes) from animal reproductive organs (gonads) and their storage for future conception.Centuries later, Western philosopher beliefs in regard to reproduction were contrary to Persian knowledge. The Greek philosophers believed that man's water (semen) contains all human characteristics, and the female uterus is only responsible for nurturing and development of fetus. After detection of the ovum (de Graaf 2(nd) half 17 century) Malpigy proposed the preformation theory (ovist) which means there is a miniature human inside ovum, that grows after Semen has entered the uterus and grow into a well-developed fetus. This hypothesis was later delegated to spermatozoa. These contradictory and inappropriate beliefs were subject to discussions and dispute, until C.E. Wolf demonstrated that the embryo is a product of the fertilization of ovum by spermatozoa.800 years prior this the sage Ferdowsi "The Great Iranian Poet" explains nicely the equal participation of man and woman in the production of the fetus and transmission of characters.After the renaissance and especially in recent years, tremendous achievements have been made in unraveling biological secrets of reproduction. There was no work o n genetics in Iran until 1936, when a genetic course was added to the biology curriculum in related colleges and universities; Iranian Genetics Society was founded in 1966, initiating a steady movement in this field.Although there was an inevitable gap during the revolution and war in our country, now there is great effort by researchers to eliminate the gap and bring us into the mainstream

    Lucas Henriques Viscardi

    Full Text Available Abstract Hominin evolution is characterized by adaptive solutions often rooted in behavioral and cognitive changes. If balancing selection had an important and long-lasting impact on the evolution of these traits, it can be hypothesized that genes associated with them should carry an excess of shared polymorphisms (trans- SNPs across recent Homo species. In this study, we investigate the role of balancing selection in human evolution using available exomes from modern (Homo sapiens and archaic humans (H. neanderthalensis and Denisovan for an excess of trans-SNP in two gene sets: one associated with the immune system (IMMS and another one with behavioral system (BEHS. We identified a significant excess of trans-SNPs in IMMS (N=547, of which six of these located within genes previously associated with schizophrenia. No excess of trans-SNPs was found in BEHS, but five genes in this system harbor potential signals for balancing selection and are associated with psychiatric or neurodevelopmental disorders. Our approach evidenced recent Homo trans-SNPs that have been previously implicated in psychiatric diseases such as schizophrenia, suggesting that a genetic repertoire common to the immune and behavioral systems could have been maintained by balancing selection starting before the split between archaic and modern humans.

Observations on the currently active mountain-building environment yield insights on processes occurring in the upper 5-15 km of the crust, and observations on an adjacent lithologically identical exhumed ancient mountain belt provide information on processes at 10-20 km in the crust. Hydrothermal fluids were mainly derived from metamorphic dehydration reactions and/or circulating topographically driven meteoric water in these mountain belts. Three geochemically and mineralogically different types of hydrothermal alteration and vein mineralisation occurred in these orogenic belts, and gold enrichment (locally economic) occurred in some examples of each of these three types. The first type of alteration involved fluids that were in or near chemical equilibrium with their greenschist facies host rocks. Fluid flow was controlled by discontinuous fractures, and by microshears and grain boundaries in host rocks, in zones from metres to hundreds of metres thick. Vein and alteration mineralogy was similar to that of the host rocks, and included calcite and chlorite. The second type of alteration occurred where the fluids were in distinct disequilibrium with the host rocks. Fracture permeability was important for fluid flow, but abundant host rock alteration occurred as well. The alteration zones were characterised by decomposition of chlorite and replacement by ankeritic carbonate in zones up to tens of metres thick. The mineralising fluid was deep-sourced and initially rock-equilibrated, with some meteoric input. The third type of mineralisation was controlled almost exclusively by fracture permeability, and host rock alteration was minor (centimetre scale). This mineralisation type commonly involved calcite and chlorite as vein and alteration minerals, and mineralisation fluids had a major

    Pharmacogenomics and pharmacoproteomics are new sciences that their goal is achieving therapeutics with maximum results and minimal side effects for each individual due to the pattern of his genome and proteome.Although they considered new and high technology sciences but in distant past, Persian sages like Avicenna also knew about importance of "personalized medicine" and used specific patterns to detect individual differences in order to select suitable medication.Based on experience and analogy they divided individuals into different categories considering characteristics like body color, body temperature, sleep-awake pattern and skeletal structure.They also paid attention to effect of environmental conditions such as climate, job and the change of seasons on the influence of medication.Considering the low cost and ease of use of these experiences, it seems that researching their opinions can uncover the historical roots of modern pharmacoproteomics and can possibly infuse new ideas in this field.

  1. Ancient migratory events in the Middle East: new clues from the Y-chromosome variation of modern Iranians.

    Viola Grugni

    Full Text Available Knowledge of high resolution Y-chromosome haplogroup diversification within Iran provides important geographic context regarding the spread and compartmentalization of male lineages in the Middle East and southwestern Asia. At present, the Iranian population is characterized by an extraordinary mix of different ethnic groups speaking a variety of Indo-Iranian, Semitic and Turkic languages. Despite these features, only few studies have investigated the multiethnic components of the Iranian gene pool. In this survey 938 Iranian male DNAs belonging to 15 ethnic groups from 14 Iranian provinces were analyzed for 84 Y-chromosome biallelic markers and 10 STRs. The results show an autochthonous but non-homogeneous ancient background mainly composed by J2a sub-clades with different external contributions. The phylogeography of the main haplogroups allowed identifying post-glacial and Neolithic expansions toward western Eurasia but also recent movements towards the Iranian region from western Eurasia (R1b-L23, Central Asia (Q-M25, Asia Minor (J2a-M92 and southern Mesopotamia (J1-Page08. In spite of the presence of important geographic barriers (Zagros and Alborz mountain ranges, and the Dasht-e Kavir and Dash-e Lut deserts which may have limited gene flow, AMOVA analysis revealed that language, in addition to geography, has played an important role in shaping the nowadays Iranian gene pool. Overall, this study provides a portrait of the Y-chromosomal variation in Iran, useful for depicting a more comprehensive history of the peoples of this area as well as for reconstructing ancient migration routes. In addition, our results evidence the important role of the Iranian plateau as source and recipient of gene flow between culturally and genetically distinct populations.

    Full Text Available Microbialites are sedimentary formations that are found throughout the geological record and are usually considered as one of the oldest traces of life on Earth. Although they have been known for more than a century and hold as an emblematic object in Earth Sciences, we yet do not understand in details how they form and how microbial processes impact their chemistry, structure and macroscopic morphology. Here, we show recent advances achieved owing to funding provided by the EPOV program on the formation of modern microbialites in the crater Lake Alchichica (Mexico. We first show that very diverse microbial communities populate these microbialites, including diverse microbial groups able to induce carbonate precipitation. We demonstrate that this microbial diversity can be preserved for several years in laboratory aquaria offering a nice opportunity for future studies to assess the relationships between biodiversity and microbialite formation. We then detail the textural modifications affecting cyanobacterial cells during the first steps of fossilization as captured in Alchichica microbialites. Finally, we report the discovery of a new deepbranching cyanobacterium species, Candidatus Gloeomargarita lithophora, able to form intracellular Ca-, Mg-, Sr- and Ba-rich carbonates and discuss the implications for the interpretation of the fossil record.

  4. Nano-structured calcite produced by micro-organisms in ancient and modern loess in Chinese Loess Plateau

    2005-12-01

    The results from transmission electron microscopy (TEM) and field emission gun scanning microscopy (FEG-SEM) investigation show that there are calcite nano-fibers (CNFs) formed during pedogenic process. The CNFs are widely distributed in the loess and red clay samples of Caoxian, Luochuan, Lingtai, Lantian, and Xifeng profiles as well as the samples of modern surface loess soils in Chinese Loess Plateau. Diameters of all the NFCs are about 40 nm, the length of the CNFs ranges from tens nanometer to several micrometers. Elongation direction of NFCs is unusual near parallel (105)* or (115)*. Crystals of NFCs arrange as bird net like and lattice-like frameworks. X-ray EDS spectra show the weak peaks of magnesium, phosphorous, and sulfur. Our investigation indicates that CNFs are in pore space of loess and paleosol and made up most of carbonate except for caliche nodular layers. Concentration of NFCs in the loess layers are significantly higher than those of paleosol layers because of leaching of carbonate in the paleosol forming environment (warn and wet paleoclimate). The "nanobacteria-like CNFs are well crystalline calcite single crystals with smoothes surfaces. The morphologies of CNFs are very unusual and different from the calcite single crystals observed in most geological environments. The CNFs are directly related to microbial activities in both ancient and modern loess. It is proposed that the intervention of organic compounds derived from microbial activities control the formation of the calcite nano-fibers. Both morphology and bulk composition of CNFs indicate that the formation of the CNFs involves bio-organics derived from microorganisms in loess deposit environment. Formation conditions of the calcite nano-fibers may information about paleoclimate, paleo-environment and paleoecology. So, the discovery of CNFs in loess-paloesol sequences can provide a new route for reconstruct paleoclimate by oxygen and carbon isotope from the CNFs.

  5. On the Contribution of Slovenian Linguistics to the History of the Ancient Greek Perfect

    Full Text Available An important contribution to the history of the Ancient Greek perfect is the study of Erika Mihevc-Gabrovec, The Disappearance of the Perfect in Late Greek (La disparition du parfait dans le grec de la basse époque. In terms of theory and content, her study continues the work of Pierre Chantraine, but somewhat diverges from her predecessor’s views on the issue of the merger between the aorist and the perfect, identifying examples of the use of the perfect even in an – according to Pierre Chantraine – relatively late period.  Some years after the publication of Erika Mihevc-Gabrovec’s book, the question of when the aorist and the perfect may have merged was raised again, to be addressed by McKay in a number of articles. Today, the views on the subject are strongly divided.   As argued by the author of this paper, one of the setbacks in examining the merger between the aorist and the perfect concerns the methodology, since researchers have tended to rely exclusively on their sense of language. A possible new approach is offered in the framework of the Slovenian theory of Natural Syntax, which has from the start paid considerable attention to English sentences of the I believe her to be intelligent type. The paper describes similar sentences in New Testament Greek, terming them “sentences of the λέγουσινἀνάστασινμὴεἶναι type”. In New Testament Greek, they display a tendency to use the present infinitive of stative verbs; relatively frequent is also the perfect infinitive (of non-stative verbs, while, as already noted in other studies, these sentences – at least in New Testament Greek – avoid the aorist infinitive. Such sentences thus bear witness to the fact that the aorist and the perfect were not fully interchangeable in New Testament Greek; the status of the aorist and perfect infinitives in sentences of the λέγουσινἀνάστασινμὴεἶναι type should also be taken into

  8. Uniqueness of human running coordination: The integration of modern and ancient evolutionary innovations

    2016-04-01

    Full Text Available Running is a pervasive activity across human cultures and a cornerstone of contemporary health, fitness and sporting activities. Yet for the overwhelming predominance of human existence running was an essential prerequisite for survival. A means to hunt, and a means to escape when hunted. In a very real sense humans have evolved to run. Yet curiously, perhaps due to running’s cultural ubiquity and the natural ease with which we learn to run, we rarely consider the uniqueness of human bipedal running within the animal kingdom. Our unique upright, single stance, bouncing running gait imposes a unique set of coordinative difficulties. Challenges demanding we precariously balance our fragile brains in the very position where they are most vulnerable to falling injury while simultaneously retaining stability, steering direction of travel, and powering the upcoming stride: all within the abbreviated time-frames afforded by short, violent ground contacts separated by long flight times. These running coordination challenges are solved through the tightly-integrated blending of primitive evolutionary legacies, conserved from reptilian and vertebrate lineages, and comparatively modern, more exclusively human, innovations. The integrated unification of these top-down and bottom-up control processes bestows humans with an agile control system, enabling us to readily modulate speeds, change direction, negotiate varied terrains and to instantaneously adapt to changing surface conditions. The seamless integration of these evolutionary processes is facilitated by pervasive, neural and biological, activity-dependent adaptive plasticity. Over time, and with progressive exposure, this adaptive plasticity shapes neural and biological structures to best cope with regularly imposed movement challenges. This pervasive plasticity enables the gradual construction of a robust system of distributed coordinated control, comprised of processes that are so deeply

    The acupoint selection was retrieved from the ancient and modern literature on the treatment of sub-healthy condition with acupuncture. The law of acupoint application was analyzed so as to provide a certain reference to the determination of acupoint prescription in clinical acupuncture. The ancient literature was retrieved from Chinese basic ancient literature database. The modern literature was retrieved from Cochrane Library, Medline, PubMed, Ovid evidence-based medicine database, Chinese biomedical literature database, China journal full-text database, VIP journal full-text database and Wanfang database. The database mining software was adopted to explore the law of acupoint application in treatment of sub-healthy conditions with ancient and modern acupuncture. The acupoint use frequency, compatibility association rule, law for meridian use and the use regularity of specific points were analyzed. In the ancient treatment for sub-healthy condition, the top five commonly used acupoints are Shenmen (HT 7), Zhaohai (KI 6), Taibai (SP 3), Daling (PC 7) and Taixi (KI 3). The most commonly combined points are Zhangmen (LR 13), Taibai (SP 3) and Zhaohai (KI 6). The most commonly used meridians are the bladder meridian of foot-taiyang, kidney meridian of foot-shaoyin and liver meridian of foot-jueyin. The most commonly used specific points are the five-shu points. The most commonly used acupoints are located in the lower limbs. In the modern treatment, the top five commonly used acupoints are Zusanli (ST 36), Sanyinjiao (SP 6), Baihui (GV 20), Shenshu (BL 23) and Guanyuan (CV 4). The most commonly supplemented points are Hegu (LI 4) and Taichong (LR 3). The most commonly used meridians are the bladder meridian of foot-taiyang, the conception vessel and the governor vessel. The most commonly used specific points are the back-shu points. The most commonly used acupoints are located in the lower limbs. After the systematic comprehension of the relevant ancient and modern

    Directory of Open Access Journals (Sweden)

    A M Adediran

    2015-12-01

    Full Text Available The article outlines the key stages in the development of modern theory of migration following the historical sequence and continuity of its basic conceptual constructs’ formation. Although the author refers to the twentieth century as a chronological framework of the text, the narrative begins from the works of E. Ravenstein published at the end of the XIX century, for they laid the foundation for future theoretical studies on migration issues. In particular, many well-known scientists still use concepts “laws of migration” and “attracting and push factors of migration” proposed by Ravenstein claiming their timeless validity or, on the contrary, criticizing them for the loss of relevance in the new social and cultural realities. The author considers as milestones of the modern theory of migration the works of the representatives of Chicago school of sociology that enriched the conceptual apparatus of the analysis of migration processes and the typology of driving causes of migration; the works of S. Stouffer, G. Zipf, E. Lee and W. Lewis, W. Zelinsky and D. Massey. Finally, the article summarizes the objective trends in today’s global development that force scientists to introduce new accents in the study of migration processes, although upon closer inspection it turns out that all “new” ideas had already been formulated in early migration studies and just got a new sound in another historical period.

    This essay explores ways to "write together" the awkwardly jointed histories of "science" and "me dicine"--but it also includes other "arts" (in the old sense) and technologies. It draws especially on the historiography of medicine, but I try to use terms that are applicable across all of science, technology, and medicine (STM). I stress the variety of knowledges and practices in play at any time and the ways in which the ensembles change. I focus on the various relations of "science" and "medicine," as they were understood for a succession of periods--from mainly agricultural societies, through industrial societies, to our biomedical present--trying to sketch a history that encompasses daily practices and understandings as well as major conceptual and technical innovations. The model is meant to facilitate inquiry across topics and across times, including those to come.

    Full Text Available Within the actual debate on citizenship within democracy, admitting a crisis in educational matters is highly relevant (NUSSBAUM, 2010; BERKOWITZ, 2001. Thus, if we want to understand why the ancient educational image is problematic and unsatisfying to the citizens of democratic governments, it is unavoidable, from the history of philosophy point of view, to quote the teaching of preeminent political theorists. Needless to say, the power of education in forming people’s character and opinions is widely recognized. Nonetheless, by looking at the history of the institution, it seems obvious that its purpose is not only to form habits but to circumscribe the knowledge of the persons in such a way as to make one set of opinions always inevitable (RUSSELL, 1961. Current paper reveals the theoretical presuppositions of the political and educational doctrines of two main figures of Ancient and Modern times, namely, Aristotle and Locke, respectively. Further considerations will ensue on whether the ancient image of virtue, or its antagonism and possible use in liberalism, has any power to represent the present conditions of equity and justice sought after in civil life within Latin American democracies.

The 1960s were a time of shortage of psychiatric APRNs, with legislation expanding the availability of mental health services. We find ourselves in a similar time with 7 million new health insurance enrollees, because of the Affordable Care Act (ACA). The expansion of health insurance coverage comes at a time when some colleges of nursing are closing master's programs in psychiatric-mental health, in lieu of the DNP mandate from the American Association of Colleges of Nursing.

    2015-09-01

    Full Text Available In this special issue of Cross-Currents, the contributing authors look at how business linked China and the world from the mid-nineteenth to the mid-twentieth century, and how Chinese and foreign companies interacted with one another, as well as with political power, long before today. Some authors concentrate on material connections, including shipping, banking, the building of railroads, the spread of the motion picture industry, international treaties, and the formation of knowledge, while others investigate the role of business culture and how entrepreneurship and networks of trust crossed borders. Both of these aspects are set against the backdrop of simultaneous Chinese state-building efforts that became evident in the state creation of a national market and the formation of political borders. All of the authors collected here draw on case studies of individual entrepreneurs or companies, just as they draw on the new historical and theoretical scholarship summarized above to fill out the picture of China’s economic development within global processes. As the contributions to this issue demonstrate, rethinking Chinese business history also forces us to rethink Chinese urban history more generally... The new pictures of business practice presented here entail a remapping of the spatial dynamics of such activities and thereby a new understanding of the making of urban China...

    Knowledge of how climate change affected species distribution in the past may help us predict the effect of ongoing environmental changes. We explore how the use of modern (AFLP fingerprinting techniques) and ancient DNA (metabarcoding P6 loop of chloroplast DNA) help to reveal past distribution of vascular plant species, dispersal processes, and effect of species traits. Based on studies of modern DNA combined with species distribution models, we show the dispersal routes and barriers to dispersal throughout the circumarctic/circumboreal region, likely dispersal vectors, the cost of dispersal in term of loss of genetic diversity, and how these relates to species traits, dispersal distance, and size of colonized region. We also estimate the expected future distribution and loss of genetic diversity and show how this relates to life form and adaptations to dispersal. To gain more knowledge on time lags in past range change events, we rely on palaeorecords. Current data on past distribution are limited by the taxonomic and time resolution of macrofossil and pollen records. We show how this may be improved by studying ancient DNA of lake sediments. DNA of lake sediments recorded about half of the flora surrounding the lake. Compared to macrofossil, the taxonomic resolution is similar but the detection rate is considerable improved. By taking into account main determinants of founder effect, dispersal vectors, and dispersal lags, we may improve our ability to forecast effects of climate change, whereas more studies on ancient DNA may provide us with knowledge on distribution time lags.

    Full Text Available Genome sequencing of the 5,300-year-old mummy of the Tyrolean Iceman, found in 1991 on a glacier near the border of Italy and Austria, has yielded new insights into his origin and relationship to modern European populations. A key finding of that study was an apparent recent common ancestry with individuals from Sardinia, based largely on the Y chromosome haplogroup and common autosomal SNP variation. Here, we compiled and analyzed genomic datasets from both modern and ancient Europeans, including genome sequence data from over 400 Sardinians and two ancient Thracians from Bulgaria, to investigate this result in greater detail and determine its implications for the genetic structure of Neolithic Europe. Using whole-genome sequencing data, we confirm that the Iceman is, indeed, most closely related to Sardinians. Furthermore, we show that this relationship extends to other individuals from cultural contexts associated with the spread of agriculture during the Neolithic transition, in contrast to individuals from a hunter-gatherer context. We hypothesize that this genetic affinity of ancient samples from different parts of Europe with Sardinians represents a common genetic component that was geographically widespread across Europe during the Neolithic, likely related to migrations and population expansions associated with the spread of agriculture.

Monetary program “Sochi 2014”, realized since 2011 is one of the most extensive and design diversified. The tradition to stamp out coins in the host city of the Olympic Games was established in Ancient Greece. They served not only as a means of exchange or as a store of value, ancient Greeks managed to make them works of art. Ancient authors’ data, concerning coinage site, time and type don’t give an accurate account of the coins we can reasonably call the “Olympic” ones. This problem has been solved by numismatologists from late XVIII century through the present. Their views of ancient “monetary program” differ. This article is focused on the special character of these discrepancies both in historical records and historiography

  10. The effect of ancient DNA damage on inferences of demographic histories

    The field of ancient DNA (aDNA) is casting new light on many evolutionary questions. However, problems associated with the postmortem instability of DNA may complicate the interpretation of aDNA data. For example, in population genetic studies, the inclusion of damaged DNA may inflate estimates o...... for a change in effective population size in this data set vanishes once the effects of putative damage are removed. Our results suggest that population genetic analyses of aDNA sequences, which do not accurately account for damage, should be interpreted with great caution....

    The theoretical motion of the individual dust grains in the lunar regolith is analyzed by using a Monte Carlo statistical code where the variables are the mass and speed distribution of meteorites at the lunar surface and the geometrical shape of impact craters. From these computations the detailed irradiation history of the grains in the ancient solar wind is traced back, over a period of 4 billion years, as a function of the grain-size. Then by combining this irradiation scheme with the results of solar wind simulation experiments, the time and depth dependent accumulation of solar wind effects in the theoretical grains (solar wind maturation) is inferred. Finally, the validity of these predictions is tentatively checked by discussing a variety of physical and chemical solar wind effects which are registered in the surface layers of lunar dust grains. Therefore these studies give a tentative scenario for the 'maturation' of the lunar regolith with respect to solar wind effects, but they also reveal useful guidelines to deduce meaningful information from such effects. In particular, they suggest a 'lunar skin' sampling technique for extracting dust grains in lunar core tubes which could help in deciphering the past activity of the ancient solar wind over a time scale of several billion years.

  13. Reading The History Manifesto as a Historian of Mathematics in Ancient China.

    The History Manifesto invites historians to consider the social and political responsibilities attached to their profession. This general concern is equally meaningful for the field of history and for the history and philosophy of science and technology. The specific concerns that motivate Jo Guldi and David Armitage lead them to advocate the "longue durée" and to insist primarily on social inequality, climate change, and governance. The concern on which this response to The History Manifesto centers is historians' social.responsibility in the waging of wars and their ethical responsibility at least not to contribute to mounting tensions. For the historian Lucien Febvre, in the immediate aftermath of World War II, a history of science and culture practiced in a certain way had a specific part to play in this regard. Febvre's practice of long-term history differed from Fernand Braudel's approach to the longue durée, in the tradition of which Guldi and Armitage situate their manifesto. This essay suggests that a historical approach to long-term history, sensitive to the concern Febvre voiced, might be helpful. It argues that long-term histories of science and technology practiced in a certain way have contributed to shaping collectives that perceive themselves as communities. Critical analysis of our practices as historians could certainly help develop awareness in our field in this respect.

    Cell-Fe(III) mineral aggregates produced by anoxygenic Fe(II)-oxidizing photoautotrophic microorganisms (photoferrotrophs) may be influential in the modern Fe cycle and were likely an integral part of ancient biogeochemical cycles on early Earth. While studies have focused on the environmental...... conditions under which modern photoferrotrophs grow and the kinetics, physiology and mechanism of Fe(II) oxidation, no systematic analyses of the physico-chemical characteristics of those aggregates, such as shape, size, density and chemical composition, have as yet been conducted. Herein, experimental...... results show most aggregates are bulbous or ragged in shape, with an average particle size of 10-40??m, and densities that typically range between 2.0 and 2.4g/cm 3; the cell fraction of the aggregates increased and their density decreased with initial Fe(II) concentration.

    Revew of published isotope-geochronological data on Ender by Land (Antarctica), which is the region of highly metamorphic formations predominant development which includes ancient rock relicts, is presented. Three tectonic-thermal events present the Archeau evolution in the region. Correlation of isotope-geochronological (U-Pb, Rb-Sr, Sm-Nd) data with micro textural processing allows to estimate tectonic-thermal events age: 3000-3100 about 2900 and about 2500 million years. Metamorphism of 3000-3100 million years age has essentially modified all the isotope systems, while model calculations for evolution of U-Pb, Rb-Sr, Sm-Nd systems have shown that rocks primary formation accurred 3500-3900 million years ago

  18. Modern and ancient red fox (Vulpes vulpes in Europe show an unusual lack of geographical and temporal structuring, and differing responses within the carnivores to historical climatic change

    2011-07-01

    Full Text Available Abstract Background Despite phylogeographical patterns being well characterised in a large number of species, and generalised patterns emerging, the carnivores do not all appear to show consistent trends. While some species tend to fit with standard theoretical phylogeographic expectations (e.g. bears, others show little obvious modern phylogeographic structure (e.g. wolves. In this study we briefly review these studies, and present a new phylogeographical study of the red fox (Vulpes vulpes throughout Europe, using a combination of ancient DNA sequences obtained from museum specimens, and modern sequences collated from GenBank. We used cytochrome b (250 bp and the mitochondrial control region (268 bp to elucidate both current and historical phylogeographical patterning. Results We found evidence for slight isolation by distance in modern populations, as well as differentiation associated with time, both of which can likely be attributed to random genetic drift. Despite high sequence diversity (11.2% cytochrome b, 16.4% control region, no evidence for spatial structure (from Bayesian trees is found either in modern samples or ancient samples for either gene, and Bayesian skyline plots suggested little change in the effective population size over the past 40,000 years. Conclusions It is probable that the high dispersal ability and adaptability of the red fox has contributed to the lack of observable differentiation, which appears to have remained consistent over tens of thousands of years. Generalised patterns of how animals are thought to have responded to historical climatic change are not necessarily valid for all species, and so understanding the differences between species will be critical for predicting how species will be affected by future climatic change.

    Recent developmental studies demonstrate that early fossil hominins possessed shorter growth periods than living humans, implying disparate life histories. Analyses of incremental features in teeth provide an accurate means of assessing the age at death of developing dentitions, facilitating direct comparisons with fossil and modern humans. It is currently unknown when and where the prolonged modern human developmental condition originated. Here, an application of x-ray synchrotron microtomography reveals that an early Homo sapiens juvenile from Morocco dated at 160,000 years before present displays an equivalent degree of tooth development to modern European children at the same age. Crown formation times in the juvenile's macrodont dentition are higher than modern human mean values, whereas root development is accelerated relative to modern humans but is less than living apes and some fossil hominins. The juvenile from Jebel Irhoud is currently the oldest-known member of Homo with a developmental pattern (degree of eruption, developmental stage, and crown formation time) that is more similar to modern H. sapiens than to earlier members of Homo. This study also underscores the continuing importance of North Africa for understanding the origins of human anatomical and behavioral modernity. Corresponding biological and cultural changes may have appeared relatively late in the course of human evolution.

    2017-01-01

    Full Text Available The study of history is becoming increasingly less interesting to students, despite the fact that the history teaching process has been continuously modernized during recent years. It is an observation which can be perceived even if we don`t make an elaborated research in the field. Some empirical data show us that students in secondary and High Schools are less interested in studying History than in studying Geography or other social sciences. The number of students who are determined to study History in universities has significantly dropped in recent years [1]. Of course, there are multiple causes and the factors behind this change are numerous and varied. In this paper we handle only some changes in teaching History in High Schools, as they are designed in History Curricula and in History textbooks. Therefore during the first sequence of this paper we shall analyze the History Curricula for High School, 11th and 12th grades, regarding their finalities (competencies, some relevant contents and the recommended pedagogical approaches about the teaching methods and the auxiliary material. In the second part of the paper we propose some teaching activities through which students would practice the specific competencies from their Curriculum for History. We aim at presenting attractive teaching material and learning methods and applying the methodological recommendations from the High school Curricula for History, 11th and 12th grades.

    Summary: Actinobacteria constitute one of the largest phyla among Bacteria and represent gram-positive bacteria with a high G+C content in their DNA. This bacterial group includes microorganisms exhibiting a wide spectrum of morphologies, from coccoid to fragmenting hyphal forms, as well as possessing highly variable physiological and metabolic properties. Furthermore, Actinobacteria members have adopted different lifestyles, and can be pathogens (e.g., Corynebacterium, Mycobacterium, Nocardia, Tropheryma, and Propionibacterium), soil inhabitants (Streptomyces), plant commensals (Leifsonia), or gastrointestinal commensals (Bifidobacterium). The divergence of Actinobacteria from other bacteria is ancient, making it impossible to identify the phylogenetically closest bacterial group to Actinobacteria. Genome sequence analysis has revolutionized every aspect of bacterial biology by enhancing the understanding of the genetics, physiology, and evolutionary development of bacteria. Various actinobacterial genomes have been sequenced, revealing a wide genomic heterogeneity probably as a reflection of their biodiversity. This review provides an account of the recent explosion of actinobacterial genomics data and an attempt to place this in a biological and evolutionary context. PMID:17804669

  3. Ancient connections among the European rivers and watersheds revealed from the evolutionary history of the genus Telestes (Actinopterygii; Cypriniformes.

    Full Text Available In order to better understand the complex geologic history of the Mediterranean area, we have analysed evolutionary history, phylogeographic structure and molecular diversity of freshwater fishes belonging to the genus Telestes. As primary freshwater fishes distributed largely in the Mediterranean basin, this genus represents a suitable model system for investigating the historical biogeography of freshwater drainage systems in southern Europe. In this investigation we have included samples representing all Telestes species and based our analyses on one mitochondrial and one nuclear gene. We have investigated phylogenetic structure inside the genus Telestes, estimated divergence times, reconstructed ancestral distribution ranges and described intraspecific molecular diversity. Diversification of Telestes started in the Early Miocene, when the ancestors of T. souffia, lineage comprising T. croaticus and T. fontinalis, and the one comprising T. pleurobipunctatus and T. beoticus got isolated. The remaining species are genetically more closely related and form a common cluster in the recovered phylogenetic trees. Complex geological history of southern Europe, including formation of continental bridges, fragmentation of landmass, closing of the sea corridor, local tectonic activities, led to complicated biogeographical pattern of this genus, caused by multiple colonization events and passovers between ancient rivers and water basins. Especially pronounced diversity of Telestes found in the Adriatic watershed in Croatia and Bosnia and Herzegovina is a consequence of a triple colonization of this area by different lineages, which led to an existence of genetically distinct species in neighboring areas. Significant intraspecific structuring is present in T. souffia, T. muticellus, T. croaticus and T. pleurobipunctatus. Besides in well-structured species, elevated levels of genetic polymorphism were found inside T. turskyi and T. ukliva, as a consequence

  6. 500-year periodicity of political instability in the history of ancient Egypt and China. Androgens at work?

    Science.gov (United States)

    Páles, Emil; Mikulecký, Miroslav

    2008-08-01

    DISCOVERY: A periodicity of 500 years has been discovered in the political history of ancient Egypt and documented by means of inferential statistics. Periods of chaos and waning of central power (some of them called "intermediate periods") recurred every 500 years. Input for the computation is the mean duration of ruling dynasties calculated per each half century. Fisher's periodogram analysis and Halberg's cosinor regression have been used. A highly significant (p god Nergal. The same periodicity has been described by the Chinese philosopher Mencius in the 3rd century B.C. and attributed to the will of tian (heaven). Egyptians elevated their war god Seth every 500 years and European kings assumed masculine nicknames. This recurring cultural pattern of aggressiveness and strife resembles overall traits of male psyche or mid-life crisis. We suggest to look for an unknown cosmophysical factor impacting the neuroendocrine system of man by raising the levels of androgens periodically. EXPLANATION HYPOTHESES: Sun impacts global weather on Earth, but there is no known significant periodicity of 500 years in solar activity. The Wheeler weather cycle almost fits the cycle of Egyptian political history. But his cold-dry periods seem to lag behind the periods of social destabilization and hence can not cause them. An alternative view (based on idealistic rather than materialistic presuppositions) is, that periodic long-term shifts of archetypes take place within the collective unconscious of mankind independently of external environment.

    Although simian foamy viruses (SFV) are the only exogenous retroviruses to infect New World monkeys (NWMs), little is known about their evolutionary history and epidemiology. Previous reports show distinct SFVs among NWMs but were limited to small numbers of captive or wild monkeys from five (Cebus, Saimiri, Ateles, Alouatta, and Callithrix) of the 15 NWM genera. Other studies also used only PCR testing or serological assays with limited validation and may have missed infection in some species. We developed and validated new serological and PCR assays to determine the prevalence of SFV in blood specimens from a large number of captive NWMs in the US (n = 274) and in captive and wild-caught NWMs (n = 236) in Peruvian zoos, rescue centers, and illegal trade markets. Phylogenetic and co-speciation reconciliation analyses of new SFV polymerase (pol) and host mitochondrial cytochrome B sequences, were performed to infer SFV and host co-evolutionary histories. 124/274 (45.2 %) of NWMs captive in the US and 59/157 (37.5 %) of captive and wild-caught NWMs in Peru were SFV WB-positive representing 11 different genera (Alouatta, Aotus, Ateles, Cacajao, Callithrix, Cebus, Lagothrix, Leontopithecus, Pithecia, Saguinus and Saimiri). Seroprevalences were lower at rescue centers (10/53, 18.9 %) compared to zoos (46/97, 47.4 %) and illegal trade markets (3/7, 8/19, 42.9 %) in Peru. Analyses showed that the trees of NWM hosts and SFVs have remarkably similar topologies at the level of species and sub-populations suggestive of co-speciation. Phylogenetic reconciliation confirmed 12 co-speciation events (p history of SFV in NWMs at the species level. Additional studies are necessary to further explore the epidemiology and natural history of SFV infection of NWMs and to determine the zoonotic potential for persons exposed to infected monkeys in captivity and in the wild.

    This article aims to evaluate and analyze the description of the modern hospital as history record, which appeared in YI Kwang Su's novel Love. This novel has mentioned in detail western style clinic, Bukgando Catholic hospital, tuberculosis sanitarium as its main space. Modern hospitals are depicted in the novel has a great significance in historical aspect as well as in literary aspect. The most data on modern hospital is laws, statistics and newspaper archives. These materials are a great help to understand the history and status of the modern hospital. Literary description here is important materials, that specific to reconstruct the appearance of the modern hospital at that time. Literary representations infuse life into the history record. In this regard, Love has special meaning in the history of Korean modern literature. Before anything else, doctor AN Bin's clinic as a first space of the novel vividly shows the reality of the Western style clinic and a general practitioner under the colonial period. The establishment of the hospital was based on 「Rules on private hospital」 declared by the Japanese Government General of Korea in 1919. According to this Rules, a private clinic's founder had to submit the documents to the director of police affairs, in which all the details were written. It included name of hospital, site location and size, floor plan of a nearby building, each size of patient's rooms, number of steps and emergency exit, bath, toilet, disinfecting room. AN Bin's clinic was a private hospital with the requirements in the rules. The descriptions of this clinic re-created real situation of private hospitals, specifically scale of hospital, interior space, conditions of patient's room at the time. The second modern hospital in the novel is Bukgando Catholic hospital. There is a lot more materials on medical activity and hospital of protestant churches than we thought. But we do not have a lot of information on catholic church's medical

    The content of Li, B, and N is examined in ancient and modern pottery and its glazes by means of (n,p) and (n,α) reactions with thermal neutrons. Most samples exhibit a proportionality between B and Li concentrations with preferred values around 0.01 at.%. One group of pottery shows nearly constant Li abundance around 0.1 at.%, the B content varying from 10 -4 at.% to 10 at.%. An explanation is given, and the individual groups of pottery are described in detail. Results for different archaeological sites of Sumerian, Babylonian, Assyrian, Phoenician and Roman provenience are presented. The data scattering of B and Li contents of samples from different places of origin varies considerably, and can be used as a measure of the economical importance of ancient centers. Local urban cultures, such as Ur, exhibit a relative data scattering around 0.2, cities with average trade relations show values around 0.4, and for the famous trade center Palmyra, 0.8 was found. The B/Li ratio of pottery indicates whether the clay used is a fresh water or a marine sediment. The B and Li contents of Euphrates pottery show systematic variations along the river valley. Several samples, found in the Mesopotamian region are highly enriched in nitrogen. This is probably due to salt precipitation in the surrounding soil after the destruction of the irrigation facilities by the Mongols in 1258. (orig.)

  15. The modern Chinese family in light of economic and legal history.

    Science.gov (United States)

    Huang, Philip C C

    2011-01-01

    Most social science theory and the currently powerful Chinese ideology of modernizationism assume that, with modern development, family-based peasant farm production will disappear, to be replaced by individuated industrial workers and the three-generation family by the nuclear family. The actual record of China’s economic history, however, shows the powerful persistence of the small family farm, as well as of the three-generation family down to this day, even as China’s GDP becomes the second largest in the world. China’s legal system, similarly, encompasses a vast informal sphere, in which familial principles operate more than individualist ones. And, in between the informal-familial and the formal-individualist, there is an enormous intermediate sphere in which the two tendencies are engaged in a continual tug of war. The economic behavior of the Chinese family unit reveals great contrasts with what is assumed by conventional economics. It has a different attitude toward labor from that of both the individual worker and the capitalist firm. It also has a different structural composition, and a different attitude toward investment, children’s education, and marriage. Proper attention to how Chinese modernity differs socially, economically, and legally from the modern West points to the need for a different kind of social science; it also lends social–economic substance to claims for a modern Chinese culture different from the modern West’s.

    Full Text Available The purpose of this research is to prove that conflict in church music is nothing new. Even in the time of the early church fathers, dissenting views on what were acceptable and unacceptable practices in church music were present. The music of the 2nd century through the 14th century is examined. The method used to find specific conflicts in church music history involved reading early Christian literature on music. When possible, both sides of the conflicts included in the project are presented. However, oftentimes only one side of an argument can be found since there is not an abundant supply of early Christian writings on music. When this is the case, a brief attempt at reconstructing the opposing side is made. The most important resources for this research were James McKinnon’s Music in Early Christian Literature and Oliver Strunk’s Source Readings in Music History: Revised Edition. These were integral to this project as they provided primary sources translated into English.

    2005-07-01

    In this hugely ambitious and exciting book Peter Watson tells the history of ideas from prehistory to the present day, seeking a new way to tell the history of the world. The book begins over a million years ago with a discussion of how the earliest ideas might have originated. Looking at animal behaviour that appears to require some thought tool-making, territoriality, counting, language (or at least sounds), pairbonding Peter Watson moves on to the apeman and the development of simple ideas such as cooking, the earliest language, the emergence of family life. All the obvious areas will be tackled the Ancient Greeks, Christian theology, the ideas of Jesus, astrological thought, the soul, the self, beliefs about the heavens, the ideas of Islam, the Crusades, humanism, the Renaissance, Gutenberg and the book, the scientific revolution, the age of discovery, Shakespeare, the idea of Revolution, the Romantic imagination, Darwin, imperialism, modernism, Freud right up to the present day and the internet. (orig./GL) [German] Beginnt die Ideengeschichte der Menschheit, als die Fruehmenschen erstmals Feuer machen, vor ca. 1,8 Millionen Jahren? Oder schon mit dem ersten Faustkeil vor etwa 2,5 Millionen Jahren? Warum entwickelte sich vor 40 000 Jahren eine komplexe Sprache? Wie kamen das Minus- und das Plus-Zeichen in die Vorstellungswelt, und wie entstand das Bild vom Paradies? Peter Watson laedt ein zu einer Expedition durch die abenteuerliche Welt menschlicher Ideen. Vom ersten Feuer, dem ersten Werkzeug und den ersten Worten ueber die Geburt der Goetter, die ersten Gesetze und die Entwicklung grosser Zentren von Wissen und Weisheit bis hin zu den umwaelzenden Ideen der Moderne: das Groesste und das Kleinste, das Selbst-Bewusstsein des Individuums und die Entdeckung des Unbewussten. Dabei ordnet Watson die riesige Materialfuelle nach drei zentralen Ideen, die fuer ihn die Geschichte der Menschheit praegen: die Seele, mehr als die Idee von einem Gott, Europa, mehr als das

    Ancient DNA analysis has revealed an involvement of the bacterial pathogen Yersinia pestis in several historical pandemics, including the second plague pandemic (Europe, mid-14(th) century Black Death until the mid-18(th) century AD). Here we present reconstructed Y. pestis genomes from plague victims of the Black Death and two subsequent historical outbreaks spanning Europe and its vicinity, namely Barcelona, Spain (1300-1420 cal AD), Bolgar City, Russia (1362-1400 AD), and Ellwangen, Germany (1485-1627 cal AD). Our results provide support for (1) a single entry of Y. pestis in Europe during the Black Death, (2) a wave of plague that traveled toward Asia to later become the source population for contemporary worldwide epidemics, and (3) the presence of an historical European plague focus involved in post-Black Death outbreaks that is now likely extinct.

    2017-12-01

    The purpose of this study is to understand the reality of imperial medicine by exploring the strategic attitude of the Japanese authority targeting the public who were not patients of Hansen's disease. For this purpose, this study examines the mass media data related to Hansen's disease published in Korea and Japan during the Japanese colonial rule. Research on Hansen's disease can be divided into medical, sociohistorical, social welfare, and human rights approach. There are medical studies and statistics on the dissemination of medical information about Hansen's disease and management measures, the history of the management of the disease, guarantee of the rights of the patients and the welfare environment, and studies on the autobiographical, literary writings and oral statements on the life and psychological conflicts of the patients. Among existing research, the topics of the study on Hansen's disease under the Japanese colonial rule include the history of the Sorokdo Island Sanatorium, investigation on the forced labor of the patients in the island, human rights violations against the patients, oral memoirs of the patients and doctors who practiced at that time. All of these studies are important achievements regarding the research on the patients. An important study of Hansen's disease in modern Japan is the work of Hujino Utaka, which introduces the isolation of and discrimination against the patients of Hansen's disease. Hujino Utaka's study examines the annihilation of people with infectious diseases in Japan and its colonies by the imperial government, which was the consequence of the imperial medical policies, and reports on the isolation of Hansen's disease patients during the war. Although these researches are important achievements in the study of Hansen's disease in modernity, their focus has mainly been on the history of isolation and exploitation in the Sorokdo Island Sanatorium and discrimination against the patients within the sanatorium, which

    This book presents contributions of mathematicians covering topics from ancient India, placing them in the broader context of the history of mathematics. Although the translations of some Sanskrit mathematical texts are available in the literature, Indian contributions are rarely presented in major Western historical works. Yet some of the well-known and universally-accepted discoveries from India, including the concept of zero and the decimal representation of numbers, have made lasting contributions to the foundation of modern mathematics.

Put in terms of good and evil, this means that it is held consistent to say that a person is autonomous and chooses evil. Autonomy, by

  2. An ancient Mediterranean melting pot: investigating the uniparental genetic structure and population history of sicily and southern Italy.

    Full Text Available Due to their strategic geographic location between three different continents, Sicily and Southern Italy have long represented a major Mediterranean crossroad where different peoples and cultures came together over time. However, its multi-layered history of migration pathways and cultural exchanges, has made the reconstruction of its genetic history and population structure extremely controversial and widely debated. To address this debate, we surveyed the genetic variability of 326 accurately selected individuals from 8 different provinces of Sicily and Southern Italy, through a comprehensive evaluation of both Y-chromosome and mtDNA genomes. The main goal was to investigate the structuring of maternal and paternal genetic pools within Sicily and Southern Italy, and to examine their degrees of interaction with other Mediterranean populations. Our findings show high levels of within-population variability, coupled with the lack of significant genetic sub-structures both within Sicily, as well as between Sicily and Southern Italy. When Sicilian and Southern Italian populations were contextualized within the Euro-Mediterranean genetic space, we observed different historical dynamics for maternal and paternal inheritances. Y-chromosome results highlight a significant genetic differentiation between the North-Western and South-Eastern part of the Mediterranean, the Italian Peninsula occupying an intermediate position therein. In particular, Sicily and Southern Italy reveal a shared paternal genetic background with the Balkan Peninsula and the time estimates of main Y-chromosome lineages signal paternal genetic traces of Neolithic and post-Neolithic migration events. On the contrary, despite showing some correspondence with its paternal counterpart, mtDNA reveals a substantially homogeneous genetic landscape, which may reflect older population events or different demographic dynamics between males and females. Overall, both uniparental genetic

  3. Lethal Surveillance: Drones and the Geo-History of Modern War

    Kindervater, Katharine Hall

    Interdisciplinary both in scope and method, my dissertation, Lethal Surveillance: Drones and the Geo-History of Modern War, examines the history of drone technology from the start of the 20th century to the present in order to understand the significance of the increasing centrality of drones to current American military engagements and security practices more generally. Much of the scholarship on drones and many other contemporary military technologies tends to view the technology as radically new, missing both the historical development of these objects as well as the perspectives and rationalities that are embedded in their use. For this research, I focused on three main periods of drone research and development: the early years of World War I and II in the UK, the Cold War, and the 1990s. In studying this history of the drone, I found that two key trends emerge as significant: the increasing importance of information to warfare under the rubric of intelligence, reconnaissance and surveillance; and a shift toward more dynamic, speedier, and individualized targeting practices. I argue that the widespread use of drones today thus represents the culmination of attempts in war to effectively link these two trends, creating a practice I call lethal surveillance -- with the armed Predator effectively closing the loop between identifying and killing targets. The concept of lethal surveillance, which in my dissertation I place squarely within the histories of modern scientific thinking and Western liberal governance, allows us to see how techniques of Western state power and knowledge production are merging with practices of killing and control in new ways, causing significant changes to both the operations of the state and to practices of war. Framing the drone through the lens of lethal surveillance, therefore, allows us to see the longer histories the drone is embedded in as well as other security practices it is connected to.

We sampled 249 free-living genomes spanning organisms in the three superkingdoms of life, Archaea, Bacteria, and Eukarya, and used the abundance of GO terms as molecular characters to produce rooted phylogenetic trees. Results revealed an early thermophilic origin of Archaea that was followed by genome reduction events in microbial superkingdoms. Eukaryal genomes displayed extraordinary functional diversity and were enriched with hundreds of novel molecular activities not detected in the akaryotic microbial cells. Remarkably, the majority of these novel functions appeared quite late in evolution, synchronized with the diversification of the eukaryal superkingdom. The distribution of GO terms in superkingdoms confirms that Archaea appears to be the simplest and most ancient form of cellular life, while Eukarya is the most diverse and recent.

    Iron (oxyhydr)oxide microbial mats in modern to ∼100 ka tufa terraces are present in a cold spring system along Ten Mile Graben, southeastern Utah, USA. Mats exhibit morphological, chemical, and textural biosignatures and show diagenetic changes that occur over millennial scales. The Jurassic Brushy Basin Member of the Morrison Formation in the Four Corners region of the USA also exhibits comparable microbial fossils and iron (oxyhydr)oxide biosignatures in the lacustrine unit. Both the modern spring system and Brushy Basin Member represent alkaline, saline, groundwater-fed systems and preserve diatoms and other similar algal forms with cellular elaboration. Two distinct suites of elements (1. C, Fe, As and 2. C, S, Se, P) are associated with microbial fossils in modern and ancient iron (oxyhydr)oxides and may be potential markers for biosignatures. The presence of ferrihydrite in ∼100 ka fossil microbial mats and Jurassic rocks suggests that this thermodynamically unstable mineral may also be a potential biomarker. One of the most extensive sedimentary records on Mars is exposed in Gale Crater and consists of non-acidic clays and sulfates possibly of lacustrine origin. These terrestrial iron (oxyhydr)oxide examples are a valuable analogue because of similar iron- and clay-rich host rock compositions and will help (1) understand diagenetic processes in a non-acidic, saline lacustrine environment such as the sedimentary rocks in Gale Crater, (2) document specific biomediated textures, (3) demonstrate how biomediated textures might persist or respond to diagenesis over time, and (4) provide a ground truth library of textures to explore and compare in extraterrestrial iron (oxyhydr)oxides, where future explorations hope to detect past evidence of life.

    Combined external milli-beam Particle Induced X-ray Emission (PIXE) and Prompt Gamma Activation Analysis (PGAA) analysis was applied to characterize the composition of paste and colorants from some fragments of Byzantine bracelets (10th-12th Centuries AD), late medieval (17th-18th Centuries AD) and modern Murano glass pieces. As fluxes, PGAA revealed the samples are soda-lime glass, except four samples - two medieval vessel white shards and two dark Byzantine fragments of bracelets - which have potash flux. Aluminium was detected in various proportions in all samples indicating different sources for the added sand. The presence of Magnesium is relevant only in one bracelet fragment suggesting the use of plant (wood?) ash and confirming that the Byzantine bracelet is manufactured from the mixture of both types of glass (natron and plant ash based). PGAA also indicated the presence of low quantities of Cadmium, high level of Arsenic and Lead (possibly lead arsenate) in one medieval sample and of ZnO in Murano glass, and of CoO traces (maximum 0.1%) in all blue-colored Byzantine, late medieval to modern Murano glass artefacts. PIXE confirmed the use of small quantities of CoO for blue color, indicated Manganese combined with Iron for dark glass, Copper for green, Lead, Tin and an Arsenic compound (orpiment?) for yellow and in the case of modern Murano glass Selenium and Cadmium to obtain a reddish color. Despite PIXE - PIGE combination is probably the best one for glass analysis, our external milli-PIXE - PGAA methods proved to be adequate complementary tools to determine many chemical elements from glass composition - Si, Na, K, Ca, Al, Mg, various metallic oxides.

    2018-01-01

    Reviewing recent, overlapping work by historians of medicine and health and of environmental history, this article proposes a further agenda upon which scholars in both fields may converge. Both environmental and medical historians can seek to understand the past two centuries of medical history in terms of a seesaw dialogue over the ways and means by which physicians and other health professionals did, and did not, consider the influence of place-airs and waters included-on disease. Modernizing and professionalizing as well as new styles of science nourished attendant aspirations for a clinical place neutrality, for a medicine in which patients' own places didn't matter to what doctors thought or did. The rise of place neutrality from the late nineteenth century onward also had close and enabling historical ties to the near-simultaneous formation of place-defined specialties-tropical medicine, bacteriological public health, and industrial medicine and hygiene.

  11. The Revelation of God, East and West: Contrasting Special Revelation in Western Modernity with the Ancient Christian East

    Directory of Open Access Journals (Sweden)

    Jacobs Nathan A.

    2017-10-01

    Full Text Available The questions of whether God reveals himself; if so, how we can know a purported revelation is authentic; and how such revelations relate to the insights of reason are discussed by John Locke, Thomas Hobbes, René Descartes, G. W. Leibniz, and Immanuel Kant, to name a few. Yet, what these philosophers say with such consistency about revelation stands in stark contrast with the claims of the Christian East, which are equally consistent from the second century through the fourteenth century. In this essay, I will compare the modern discussion of special revelation from Thomas Hobbes through Johann Fichte with the Eastern Christian discussion from Irenaeus through Gregory Palamas. As we will see, there are noteworthy differences between the two trajectories, differences I will suggest merit careful consideration from philosophers of religion.

  12. Genomic validation of the differential preservation of population history in modern human cranial anatomy.

    2017-01-01

    In modern humans, the significant correlation between neutral genetic loci and cranial anatomy suggests that the cranium preserves a population history signature. However, there is disagreement on whether certain parts of the cranium preserve this signature to a greater degree than other parts. It is also unclear how different quantitative measures of phenotype affect the association of genetic variation and anatomy. Here, we revisit these matters by testing the correlation of genetic distances and various phenotypic distances for ten modern human populations. Geometric morphometric shape data from the crania of adult individuals (n = 224) are used to calculate phenotypic P ST , Procrustes, and Mahalanobis distances. We calculate their correlation to neutral genetic distances, F ST , derived from single nucleotide polymorphisms (SNPs). We subset the cranial data into landmark configurations that include the neurocranium, the face, and the temporal bone in order to evaluate whether these cranial regions are differentially correlated to neutral genetic variation. Our results show that P ST , Mahalanobis, and Procrustes distances are correlated with F ST distances to varying degrees. They indicate that overall cranial shape is significantly correlated with neutral genetic variation. Of the component parts examined, P ST distances for both the temporal bone and the face have a stronger association with F ST distances than the neurocranium. When controlling for population divergence time, only the whole cranium and the temporal bone have a statistically significant association with F ST distances. Our results confirm that the cranium, as a whole, and the temporal bone can be used to reconstruct modern human population history. © 2016 Wiley Periodicals, Inc.

  13. [From influence to confluence : positioning the history of pre-modern Korean medicine in East Asia].

    Suh, Soyoung

    2010-12-31

    This article surveys studies focusing on pre-modern Korean medicine, which are both written in English and analyzed primary sources up to 1876. Overall, the history of pre-modern Korean medicine is an unknown filed in Anglophone academia. Yung Sik Kim's, James Palais's, and Carter Ecart's problematization of the nationalist framework of Korean scholarship partially explains the marginality of the field. Addressing these criticisms, this review argues that pre-modern Korean medicine's uneasy task lies in both elaborating Korea's own experience of medicine, while simultaneously avoiding making the "Korean" category itself essential. Korean narratives of premodern medicine need to go beyond the mere territorilalization of Korean medicine against its Chinese, Japanese, or Western counterparts, thereby to tackle the field's own boundary of research objects. The existing scholarship in English responds to this challenge by primarily examining the way in which Korea has shared textual tradition with China. Sirhak scholars' innovation in medicine, visual representation of Tongŭi bogam, Korean management of epidemics in the eleventh century, and Korean indexing of local botanicals, engages not only native achievements, but also the process of modifying medicine across geographical and political boundaries. More to the point, the emerging native narratives, although written in Korean, are implicitly resonant with those currently present in Anglophone academia. Taking "tension," "intertextuality," and "local traits" as a lens, this article assesses a series of current research in Korea. Aiming to go beyond appeals for a "distinctively" Korean experience of medicine, the future study of Korean pre-modern medicine will further elucidate confluences of different flows, such as "Chinese and Korean," "universal and local," "center and periphery," and "native and foreign," which will eventually articulate a range of Korean techniques of creating a bricolage in medicine.

  14. Activation of the Nrf2 Cell Defense Pathway by Ancient Foods: Disease Prevention by Important Molecules and Microbes Lost from the Modern Western Diet.

    Directory of Open Access Journals (Sweden)

    Donald R Senger

    Full Text Available The Nrf2 (NFE2L2 cell defense pathway protects against oxidative stress and disorders including cancer and neurodegeneration. Although activated modestly by oxidative stress alone, robust activation of the Nrf2 defense mechanism requires the additional presence of co-factors that facilitate electron exchange. Various molecules exhibit this co-factor function, including sulforaphane from cruciferous vegetables. However, natural co-factors that are potent and widely available from dietary sources have not been identified previously. The objectives of this study were to investigate support of the Nrf2 cell defense pathway by the alkyl catechols: 4-methylcatechol, 4-vinylcatechol, and 4-ethylcatechol. These small electrochemicals are naturally available from numerous sources but have not received attention. Findings reported here illustrate that these compounds are indeed potent co-factors for activation of the Nrf2 pathway both in vitro and in vivo. Each strongly supports expression of Nrf2 target genes in a variety of human cell types; and, in addition, 4-ethylcatechol is orally active in mice. Furthermore, findings reported here identify important and previously unrecognized sources of these compounds, arising from biotransformation of common plant compounds by lactobacilli that express phenolic acid decarboxylase. Thus, for example, Lactobacillus plantarum, Lactobacillus brevis, and Lactobacillus collinoides, which are consumed from a diet rich in traditionally fermented foods and beverages, convert common phenolic acids found in fruits and vegetables to 4-vinylcatechol and/or 4-ethylcatechol. In addition, all of the alkyl catechols are found in wood smoke that was used widely for food preservation. Thus, the potentially numerous sources of alkyl catechols in traditional foods suggest that these co-factors were common in ancient diets. However, with radical changes in food preservation, alkyl catechols have been lost from modern foods. The

    The mantle of the modern Earth is relatively oxidised compared to the initially reducing conditions inferred for core formation. The timing of the oxidation of the mantle is not conclusively resolved but has important implications for the timing of the development of the hydrosphere and atmosphere. In order to examine the timing of this oxidation event, we present iron isotope data from three exceptionally well preserved komatiite localities, Belingwe (2.7 Ga), Vetreny (2.4 Ga) and Gorgona (0.089 Ga). Measurements of Fe isotope compositions of whole-rock samples are complemented by the analysis of olivine, spinel and pyroxene separates. Bulk-rock and olivine Fe isotope compositions (δ57Fe) define clear linear correlations with indicators of magmatic differentiation (Mg#, Cr#). The mean Fe isotope compositions of the 2.7-2.4 Ga and 0.089 Ga samples are statistically distinct and this difference can be explained by greater extent of partial melting represented by the older samples and higher mantle ambient temperatures in the Archean and early Proterozoic relative to the present day. Significantly, samples of all ages define continuous positive linear correlations between bulk rock δ57Fe and V/Sc and δ57Fe and V, and between V/Sc and V with TiO2, providing evidence for the incompatible behaviour of V (relative to Sc) and of isotopically heavy Fe. Partial melting models calculated using partition coefficients for V at oxygen fugacities (fO2s) of 0 and + 1 relative to the fayalite-magnetite-quartz buffer (FMQ) best match the data arrays, which are defined by all samples, from late Archean to Tertiary. These data, therefore, provide evidence for komatiite generation under moderately oxidising conditions since the late Archean, and argue against a change in mantle fO2 concomitant with atmospheric oxygenation at ~ 2.4 Ga.

    Full Text Available Emperor Shen-Nung was the second of China′s mythical emperors (3500-2600 BCE. Widely considered the father of Chinese medicine, he catalogued over 365 species of medicinal plants which he personally tasted. Through his treatise ′Shen Nung Benchau Jing′, we relive Emperor Shen-Nung′s contribution to urology with reference to his management of erectile dysfunction. Time-related sources in medical and historical literature were reviewed, including the ′Shen Nung Benchau Jing′ (The medicine book of Emperor Shen-Nung, archives and manuscripts at the Wellcome History of Medicine Collection, the Royal Society of Medicine, London, The Hong Kong Museum of Medical Sciences, and The Museum of Medical History, Shanghai, China. Chinese traditional herbal medicine began approximately 5000 years ago. Agricultural clan leader, Emperor Shen-Nung, was said to have a ′crystal-like belly′ to watch the reactions in his own stomach of the herbs he collected. Ginseng was among of Shen Nung′s contributions to herbal medicine. He experienced a warm and sexually pleasurable feeling after chewing the root. He advocated this as a treatment for erectile dysfunction and used it to stimulate sexual appetite. The reputation of ginseng as an aphrodisiac is based on the doctrine of signatures, since the adult root has a phallic shape. Shen-Nung believed that ginseng′s resemblance to the human form is proof of its rejuvenative and aphrodisiac properties. It was believed that the closer the similarity to the human figure, the more potent the root. The use of ginseng for erectile dysfunction by Emperor Shen-Nung was unique for its time. It continues to hold parallels as a modern-day herbal aphrodisiac 5000 years on.

    Catalase is well-known as an antioxidant dismutating H 2 O 2 to O 2 and H 2 O. However, catalases evolved when metabolism was largely sulfur-based, long before O 2 and reactive oxygen species (ROS) became abundant, suggesting catalase metabolizes reactive sulfide species (RSS). Here we examine catalase metabolism of H 2 S n , the sulfur analog of H 2 O 2 , hydrogen sulfide (H 2 S) and other sulfur-bearing molecules using H 2 S-specific amperometric electrodes and fluorophores to measure polysulfides (H 2 S n ; SSP4) and ROS (dichlorofluorescein, DCF). Catalase eliminated H 2 S n , but did not anaerobically generate H 2 S, the expected product of dismutation. Instead, catalase concentration- and oxygen-dependently metabolized H 2 S and in so doing acted as a sulfide oxidase with a P 50 of 20mmHg. H 2 O 2 had little effect on catalase-mediated H 2 S metabolism but in the presence of the catalase inhibitor, sodium azide (Az), H 2 O 2 rapidly and efficiently expedited H 2 S metabolism in both normoxia and hypoxia suggesting H 2 O 2 is an effective electron acceptor in this reaction. Unexpectedly, catalase concentration-dependently generated H 2 S from dithiothreitol (DTT) in both normoxia and hypoxia, concomitantly oxidizing H 2 S in the presence of O 2 . H 2 S production from DTT was inhibited by carbon monoxide and augmented by NADPH suggesting that catalase heme-iron is the catalytic site and that NADPH provides reducing equivalents. Catalase also generated H 2 S from garlic oil, diallyltrisulfide, thioredoxin and sulfur dioxide, but not from sulfite, metabisulfite, carbonyl sulfide, cysteine, cystine, glutathione or oxidized glutathione. Oxidase activity was also present in catalase from Aspergillus niger. These results show that catalase can act as either a sulfide oxidase or sulfur reductase and they suggest that these activities likely played a prominent role in sulfur metabolism during evolution and may continue do so in modern cells as well. This also appears

    Full Text Available The article deals with with the possibility of researching and mapping female painters’ self-portraits with the key of queer interpretation and with the accent on women’s and queer writings. The research of female selfportraits from this perspective addresses the new approach to modern art history, and the possibilities of construction/conceptualization/readings/reflection of gender identity of the artist herself as author and observer of the painting. Theoretical analysis of self-portraits and individual works from the opus of Nadežda Petrović, Danica Jovanović, Milena Pavlović Barili, Nasta Rojc, Beta Vukanović and Natalija Cvetković was conducted.

    Physical asset protection is the principal objective of many security and safeguard measures. One well-known means of asset protection is two-person control. This paper reviews literature regarding two-person control to gain insight into its origin, first demonstrated uses, and its presence in several modern industries. This literature review of two-person control is intended to benefit people and organizations with a desire to understand its origins and how the practice has evolved over time, as well as give some insight into the flexibility of this safeguarding technique. The literature review is focused in four main sections: (1) defining two-person control, (2) early history, (3) two-person control in modern industry, and (4) a theory on how two- person control entered modern industry.

    2015-02-01

    Dental calculus (calcified tartar or plaque) is today widespread on modern human teeth around the world. A combination of soft starchy foods, changing acidity of the oral environment, genetic pre-disposition, and the absence of dental hygiene all lead to the build-up of microorganisms and food debris on the tooth crown, which eventually calcifies through a complex process of mineralisation. Millions of oral microbes are trapped and preserved within this mineralised matrix, including pathogens associated with the oral cavity and airways, masticated food debris, and other types of extraneous particles that enter the mouth. As a result, archaeologists and anthropologists are increasingly using ancient human dental calculus to explore broad aspects of past human diet and health. Most recently, high-throughput DNA sequencing of ancient dental calculus has provided valuable insights into the evolution of the oral microbiome and shed new light on the impacts of some of the major biocultural transitions on human health throughout history and prehistory. Here, we provide a brief historical overview of archaeological dental calculus research, and discuss the current approaches to ancient DNA sampling and sequencing. Novel applications of ancient DNA from dental calculus are discussed, highlighting the considerable scope of this new research field for evolutionary biology and modern medicine.

    The deposits of siliceous hydrothermal springs are known to capture and preserve a wide range of microbial fossil information. The recent discovery of hydrothermal silica at Home Plate, Columbia Hills, Mars has once again raised interest in the potential importance of ancient spring sinters as targets for future astrobiological mission to Mars. To create additional context information to support future in situ missions to Mars, we have documented systematic changes in the mineralogy and microtexture of modern siliceous hot spring deposits, observed along gradients in temperature, pH and flow velocity. Specific objectives are to: 1) identify chemical and physical factors that promote early diagenetic transformations of amorphous silica (opal-A), to progressively more ordered and crystalline phases (cristobalite, tridymite and quartz); 2) determine the composition and abundance of minor mineral phases, especially clays, in relationship to pH, temperature and paragenesis; and 3) to assess the usefulness of sinter mineralogy and microtexture in reconstructing the paleoenvironmental records preserved in ancient deposits. Study sites for acidic (pH 2-5) sinters included Nymph Creek, located in the Norris Geyser Basin of Yellowstone National Park (YNP). Active alkaline (pH 7-10) springs included Rabbit Creek, Steep Cone and Mound Spring located in the Lower Geyser Basin, YNP. Field measurements in active springs included pH, temperature and flow velocity, along with general microfacies assignments. To better constrain types and rates of silica diagenesis, the study also sampled older (Holocene-Pleistocene-aged) deposits. Laboratory analyses included X-ray powder diffraction (XRPD), thermal infrared spectroscopy (TIR) and thin section petrography for characterizing sinter microtextures and for placing mineral phases (identified by XRPD and TIR) into a time-ordered diagenetic framework. In analyzing the phyllosilicates present in sinters, we applied clay separation and

    A gender role is a set of societal norms dictating what types of behaviors are considered desirable or appropriate for a person based on their sex. However, socially constructed gender roles can lead to equal rights between genders but also to severe disadvantages and discrimination with a remarkable variety between different countries. Based on social indicators and gender statistics, “women in the Arab region are on average more disadvantaged economically, politically, and socially than women in other regions.” According to Banduras’ social learning theory, we argue that profound knowledge of the historical contributions of Ancient Egyptian female pioneers in science, arts, and even in ruling Egypt as Pharaohs can improve today’s gender role in Egypt and Middle Eastern countries. Therefore, this article provides an elaborate review of the gender role of women in Ancient Egypt, outlining their prominence, influence, and admiration in ancient societies, and discusses the possible psychological impact of this knowledge on today’s gender role. We suggest that future empirical research should investigate how enhancing the knowledge of women from Ancient Egypt can improve today’s gender role in Egypt and the Middle East. Bandura’s social learning theory is outlined as a possible framework for future research. PMID:28105022

    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.

    Cardiopulmonary resuscitation (CPR) is relatively novel branch of medical science, however first descriptions of mouth-to-mouth ventilation are to be found in the Bible and literature is full of descriptions of different resuscitation methods - from flagellation and ventilation with bellows through hanging the victims upside down and compressing the chest in order to stimulate ventilation to rectal fumigation with tobacco smoke. The modern history of CPR starts with Kouwenhoven et al. who in 1960 published a paper regarding heart massage through chest compressions. Shortly after that in 1961Peter Safar presented a paradigm promoting opening the airway, performing rescue breaths and chest compressions. First CPR guidelines were published in 1966. Since that time guidelines were modified and improved numerously by two leading world expert organizations ERC (European Resuscitation Council) and AHA (American Heart Association) and published in a new version every 5 years. Currently 2010 guidelines should be obliged. In this paper authors made an attempt to present history of development of resuscitation techniques and methods and assess the influence of previous lifesaving methods on nowadays technologies, equipment and guidelines which allow to help those women and men whose life is in danger due to sudden cardiac arrest. © 2015 MEDPRESS.

    1994-01-01

    The history of cementitious materials goes back to ancient times. The Greeks and Romans used calcined limestone and later developed pozzolanic cement by grinding together lime and volcanic ash called open-quotes pozzolanclose quotes which was first found near Port Pozzuoli, Italy. The ancient Chinese used lime-pozzolanic mixes to build the Great Wall. The ancient Egyptians used calcined impure gypsum to build the Great Pyramid of Cheops. The extraordinary stability and durability of these materials has impressed us, when so much dramatically damaged infrastructure restored by using modern portland cement now requires rebuilding. Stability and durability of cementitious materials have attracted intensive research interest and contractors' concerns, as does immobilization of radioactive and hazardous industrial waste in cementitious materials. Nuclear waste pollution of the environment and an acceptable solution for waste management and disposal constitute among the most important public concerns. The analogy of ancient cementitious materials to modern Portland cement could give us some clues to study their stability and durability. This present study examines selected results of studies of ancient building materials from France, Italy, China, and Egypt, combined with knowledge obtained from the behavior of modern portland cement to evaluate the potential for stability and durability of such materials in nuclear waste forms

    After the adjustment of disciplinary categorization of Chinese colleges in 2011, world history, along with Chinese history and archeology, became the first-level disciplines in history. As a first-level discipline, world history has a meaning clearly different from its western sense: it is not a simply course, nor a single field, but a disciplinary system combined by many second-level disciplines, including ancient world history, modern world history, history of specific nations or regions, and history of specialized subjects.

  12. Pitfalls in comparing modern hair and fossil bone collagen C and N isotopic data to reconstruct ancient diets: a case study with cave bears (Ursus spelaeus).

    2014-01-01

    Stable isotope analyses provide one of the few means to evaluate diet of extinct taxa. However, interpreting isotope data from bone collagen of extinct animals based on isotopic patterns in different tissues of modern animal proxies is precarious. For example, three corrections are needed before making comparisons of recent hair and ancient bone collagen: calibration of carbon-13 variations in atmospheric CO2, different isotopic discrimination between diet-hair keratin and diet-bone collagen, and time averaging of bone collagen versus short-term record in hair keratin. Recently, Robu et al. [Isotopic evidence for dietary flexibility among European Late Pleistocene cave bears (Ursus spelaeus). Can J Zool. 2013;91:227-234] published an article comparing extant carbon (δ(13)C) and nitrogen (δ(15)N) stable isotopic data of European cave bear bone collagen with those of Yellowstone Park grizzly bear hair in order to test the prevailing assumption of a largely vegetarian diet among cave bears. The authors concluded that cave bears were carnivores. This work is unfortunately unfounded as the authors failed to consider the necessary corrections listed above. When these corrections are applied to the Romanian cave bears, these individuals can be then interpreted without involving consumption of high trophic-level food, and environmental changes are probably the reason for the unusual isotopic composition of these cave bears in comparison with other European cave bears, rather than a change of diet. We caution researchers to pay careful attention to these factors when interpreting feeding ecology of extinct fauna using stable isotope techniques.

  13. Sedimentary processes in modern and ancient oceanic arc settings: evidence from the Jurassic Talkeetna Formation of Alaska and the Mariana and Tonga Arcs, western Pacific

    Sediment deposited around oceanic volcanic ares potentially provides the most complete record of the tectonic and geochemical evolution of active margins. The use of such tectonic and geochemical records requires an accurate understanding of sedimentary dynamics in an arc setting: processes of deposition and reworking that affect the degree to which sediments represent the contemporaneous volcanism at the time of their deposition. We review evidence from the modern Mariana and Tonga arcs and the ancient arc crustal section in the Lower Jurassic Talkeetna Formation of south-central Alaska, and introduce new data from the Mariana Arc, to produce a conceptual model of volcaniclastic sedimentation processes in oceanic arc settings. All three arcs are interpreted to have formed in tectonically erosive margin settings, resulting in long-term extension and subsidence. Debris aprons composed of turbidites and debris flow deposits occur in the immediate vicinity of arc volcanoes, forming relatively continuous mass-wasted volcaniclastic records in abundant accommodation space. There is little erosion or reworking of old volcanic materials near the arc volcanic front. Tectonically generated topography in the forearc effectively blocks sediment flow from the volcanic front to the trench; although some canyons deliver sediment to the trench slope, most volcaniclastic sedimentation is limited to the area immediately around volcanic centers. Arc sedimentary sections in erosive plate margins can provide comprehensive records of volcanism and tectonism spanning arc may be best reconstructed from sediments of the debris aprons for intervals up to ~ 20 My but no longer, because subduction erosion causes migration of the forearc basin crust and its sedimentary cover toward the trench, where there is little volcaniclastic sedimentation and where older sediments are dissected and reworked along the trench slope.

    'Number rules the universe.' The Pythagoras 'If you wish to forsee the future of mathematics our course is to study the history and present conditions of the science.' Henri Poincaré 'The primary source (Urqell) of all mathematics are integers.' Hermann Minkowski This paper is written to commemorate the centennial anniversary of the Mathematical Association of America. It deals with a short history of different kinds of natural numbers including triangular, square, pentagonal, hexagonal and k-gonal numbers, and their simple properties and their geometrical representations. Included are Euclid's and Pythagorean's main contributions to elementary number theory with the main contents of the Euclid Elements of the 13-volume masterpiece of mathematical work. This is followed by Euler's new discovery of the additive number theory based on partitions of numbers. Special attention is given to many examples, Euler's theorems on partitions of numbers with geometrical representations of Ferrers' graphs, Young's diagrams, Lagrange's four-square theorem and the celebrated Waring problem. Included are Euler's generating functions for the partitions of numbers, Euler's pentagonal number theorem, Gauss' triangular and square number theorems and the Jacobi triple product identity. Applications of the theory of partitions of numbers to different statistics such as the Bose- Einstein, Fermi- Dirac, Gentile, and Maxwell- Boltzmann statistics are briefly discussed. Special attention is given to pedagogical information through historical approach to number theory so that students and teachers at the school, college and university levels can become familiar with the basic concepts of partitions of numbers, partition functions and their modern applications, and can pursue advanced study and research in analytical and computational number theory.

    Ecuador's YasunI Man and the Biosphere Reserve-located at the intersection of the Amazon, the Andes mountains, and the equator-is home to extraordinary biodiversity and a recently contacted Amazonian indigenous group known as the Waorani (or Huaorani). Relatives of the Waorani, the Tagaeri and Taromenane, still live in voluntary isolation deep in the reserve, with no peaceful contact with the outside world. The YasunI Biosphere Reserve also sits atop large reserves of crude oil, Ecuador's chief export, and contains an abundance of valuable timber species. This volatile combination has led to intense conflicts, and subsequently, increased international interest and concern. To make the issues confronting YasunI more accessible to a growing audience of interested parties, we synthesized information on the biological, social, and political issues of the region, providing a concise overview of its modern history and conservation challenges. We constructed a chronology of key events in the YasunI region over the past century and a series of maps designed to guide readers to a better understanding of the area's complicated array of overlapping designations. Main topics of analysis and discussion include: the Waorani and their ancestors living in voluntary isolation, YasunI National Park, illegal logging, missionary impacts, oil-development-related impacts and conflicts, and the Ecuadorian government's innovative YasunI-ITT Initiative (ITT: Ishpingo-Tiputini-Tambococha).

  20. The history of modern spinal traction with particular reference to neural disorders.

    Shterenshis, M V

    1997-03-01

    The last 200 years of the history of spinal traction is described in the present article. The study starts at the end of the 18th century with the works of JA Venel (1789) who tried to apply the Hippocratic idea to modern surgery. Orthopedic specialists of the last century were mostly preoccupied with corsets and the method gained broader popularity when neurologists paid attention to the similar method of suspension. The Russian neurologist Osip Mochutkovsky described suspension as a method for the treatment of tabes dorsalis in an article published in the Russian magazine 'Vratch' in 1883. His works became known in Europe when JM Charcot paid attention to it and published a special short monograph on this subject in 1889. This work was translated into English (1889) and Russian (1890) and the method became popular in the treatment of tabes dorsalis and other neurological diseases. The eminent Russian neurologist VM Bekhterev proposed the combination of body suspension with cervical traction (1893). Some years later Gilles de la Tourette promoted the use of spinal traction in his neurological clinic (1897). Unfortunately neurologists worked without the cooperation of orthopedic specialists. During the first decades of the 20th century suspension was also replaced by traction in neurology. This method was used by both neurologists and orthopedic specialists but in the last decades neurologists lost their interests in it and it found greater use in traumatology and in spinal surgery where it is still in use today.

    2017-09-01

    Argument In recent decades a large body of scholarship on the first half of twentieth-century China has successfully shown the ways in which history and historiography had been constructed at the time, as well as the links between history, national identity, education, and politics that was forged during this period. In this paper, I examine Qing intellectual history, in particular that of the mid or "High Qing." I discuss the development of the historiography of this field in the early twentieth century by drawing on the larger developments in historiography; by demonstrating how these developments had shaped Qing intellectual history for later times; by focusing on the historical actors' sense of the importance of "science," being "scientific," and "modernization"; and, by unraveling the intimate connections to older historiographical narratives going back all the way to the eighteenth and nineteenth centuries.

    Directory of Open Access Journals (Sweden)

    Michela Rosso

    2016-06-01

    Full Text Available It has often been remarked that modern architecture in Britain began late and that its emergence largely depended on the contribution of a massive influx of European exiles seeking refuge from the political and racial persecution of totalitarian regimes. In the attempt to discard the tired narrative of Britain’s insular modernism as a mere echo of continental European achievements, an alternative historiography has recently directed attention to Britain’s own distinctive and original version of modern architecture in the 1930s. Through the examination of a small group of articles, books and pamphlets on English modern architecture written by English authors and published in the mid-1930s, this paper argues that the emergence of a distinctive version of architectural modernism in Britain was paralleled by the development of an equally original brand of architectural criticism and historiography.

    The Canaanites inhabited the Levant region during the Bronze Age and established a culture that became influential in the Near East and beyond. However, the Canaanites, unlike most other ancient Near Easterners of this period, left few surviving textual records and thus their origin and relationship to ancient and present-day populations remain unclear. In this study, we sequenced five whole genomes from ∼3,700-year-old individuals from the city of Sidon, a major Canaanite city-state on the Eastern Mediterranean coast. We also sequenced the genomes of 99 individuals from present-day Lebanon to catalog modern Levantine genetic diversity. We find that a Bronze Age Canaanite-related ancestry was widespread in the region, shared among urban populations inhabiting the coast (Sidon) and inland populations (Jordan) who likely lived in farming societies or were pastoral nomads. This Canaanite-related ancestry derived from mixture between local Neolithic populations and eastern migrants genetically related to Chalcolithic Iranians. We estimate, using linkage-disequilibrium decay patterns, that admixture occurred 6,600-3,550 years ago, coinciding with recorded massive population movements in Mesopotamia during the mid-Holocene. We show that present-day Lebanese derive most of their ancestry from a Canaanite-related population, which therefore implies substantial genetic continuity in the Levant since at least the Bronze Age. In addition, we find Eurasian ancestry in the Lebanese not present in Bronze Age or earlier Levantines. We estimate that this Eurasian ancestry arrived in the Levant around 3,750-2,170 years ago during a period of successive conquests by distant populations. Copyright © 2017 The Author(s).

    Full Text Available This article aims to evaluate and analyze the description of the modern hospital as history record, which appeared in YI Kwang Su’s novel Love. This novel has mentioned in detail western style clinic, Bukgando Catholic hospital, tuberculosis sanitarium as its main space. Modern hospitals are depicted in the novel has a great significance in historical aspect as well as in literary aspect. The most data on modern hospital is laws, statistics and newspaper archives. These materials are a great help to understand the history and status of the modern hospital. Literary description here is important materials, that specific to reconstruct the appearance of the modern hospital at that time. Literary representations infuse life into the history record. In this regard, Love has special meaning in the history of Korean modern literature. Before anything else, doctor AN Bin’s clinic as a first space of the novel vividly shows the reality of the Western style clinic and a general practitioner under the colonial period. The establishment of the hospital was based on 「Rules on private hospital」 declared by the Japanese Government General of Korea in 1919. According to this Rules, a private clinic’s founder had to submit the documents to the director of police affairs, in which all the details were written. It included name of hospital, site location and size, floor plan of a nearby building, each size of patient’s rooms, number of steps and emergency exit, bath, toilet, disinfecting room. AN Bin’s clinic was a private hospital with the requirements in the rules. The descriptions of this clinic re-created real situation of private hospitals, specifically scale of hospital, interior space, conditions of patient’s room at the time. The second modern hospital in the novel is Bukgando Catholic hospital. There is a lot more materials on medical activity and hospital of protestant churches than we thought. But we do not have a lot of information on

  12. [Knowledge of the "Gräfenberg zone" and female ejaculation in ancient Indian sexual science. A medical history contribution].

    Syed, R

    1999-01-01

    Ancient Indian texts in sexology (kamaśastra) from the 11th century onwards prove that their authors knew about the area later termed the "Gräfenberg zone" in Europe, as well as about the female ejaculation connected with the stimulation of this area. The Gräfenberg zone is a sexually arousable zone in the front part of the vagina, stimulation of which can lead to the discharge of liquid from the urethra, a phenomenon which is described as female ejaculation. The german gynaecologist Ernst Gräfenberg, who worked in America, described this zone, situated beneath the clitoris, for the first time (at least in this century) in Western medicine in an article published in 1950. (There are, however, evidences, that the 17th-century anatomist Regnier de Graaf had knowledge about the mentioned erogenous zone as well as female ejaculation.) Since the 1980s the so-called Gräfenberg zone, popularly termed "G-spot", and female ejaculation have been controversially discussed medically as well as in popular science, first in the United States, then in Europe; both phenomena have meanwhile been accepted as facts in medical manuals and reference books (e.g. the "Pschyrembel"). Whereas the oldest and most well-known sexological-erotological work of Ancient India, the Kamasutra, dating probably from the third century A.D., apparently did not know the Gräfenberg zone and female ejaculation, texts such as the Pañcasayaka (11th century), Jayamangala (Yaśodhara's commentary on the Kamasutra from the 13th century), the Ratirahasya (13th century), as well as the late kamaśastra-works Smaradipika and Anangaranga (16th century?) demonstrably describe both, the Gräfenberg zone and female ejaculation, in great detail. The female ejaculation is described already in the 7th century in a non-kamaśastra-text, in a work of the poet Amaru called the Amaruśataka.

    Differentiation of disease and differentiation of syndrome are equally important in the di-agnosis and treatment of TCM. Disease is the entire process of some abnormal life state and syndrome is a cer-tain stage in the abnormal process in the life. The terms of disease and syndrome are related with each other. In the study of the ancient and modern literatures on the term Wang Bi(尪痹),it was found that the term for syndrome was also involved. Wang Bi(尪痹)is the new term of a disease proposed by TCM master,Jiao Shude. By investigating the name and origin of the disease,Wan Bi was identified as the term of syndrome. The connection of Wang Bi(尪痹)and Wan Bi was attempted to build so as to contribute to the correct un-derstanding of the disease and construction of medical history in TCM.%中医诊治强调辨病与辨证并重,中医学探讨某病时兼及“病”“证”。疾病指人体某种异常生命状态的全过程,而证候是这个全部生命异常过程中的某个阶段。病证名即与病、证发生发展相关的称谓。在考察古今文献中与“尪痹”相关称谓时,发现还有证名的存在,因此为客观全面,该文使用了“病证名”而非“病名”的概念。“尪痹”是已故中医学家焦树德提出的新病名,考察古今文献中与“尪痹”相关的称谓,可以发现还有证名的存在。对这些病证的名实与源流进行考察,考证“尪痹”之源,辨析病证名“顽痹”。力图呈现与“尪痹”相关病证名的大致面貌,以利于准确把握这一疾病,俾于中医疾病史的建构。

    Widely distributed taxa provide an opportunity to compare biogeographic responses to climatic fluctuations on multiple continents and to investigate speciation. We conducted the most geographically and genomically comprehensive study to date of the red fox (Vulpes vulpes), the world's most widely distributed wild terrestrial carnivore. Analyses of 697 bp of mitochondrial sequence in ~1000 individuals suggested an ancient Middle Eastern origin for all extant red foxes and a 400 kya (SD = 139 kya) origin of the primary North American (Nearctic) clade. Demographic analyses indicated a major expansion in Eurasia during the last glaciation (~50 kya), coinciding with a previously described secondary transfer of a single matriline (Holarctic) to North America. In contrast, North American matrilines (including the transferred portion of Holarctic clade) exhibited no signatures of expansion until the end of the Pleistocene (~12 kya). Analyses of 11 autosomal loci from a subset of foxes supported the colonization time frame suggested by mtDNA (and the fossil record) but, in contrast, reflected no detectable secondary transfer, resulting in the most fundamental genomic division of red foxes at the Bering Strait. Endemic continental Y-chromosome clades further supported this pattern. Thus, intercontinental genomic exchange was overall very limited, consistent with long-term reproductive isolation since the initial colonization of North America. Based on continental divergence times in other carnivoran species pairs, our findings support a model of peripatric speciation and are consistent with the previous classification of the North American red fox as a distinct species, V. fulva. © 2014 John Wiley & Sons Ltd.

    Full Text Available En la discusión actual sobre la ciudanía en democracia es central admitir una crisis en la educación (NUSSBAUM, 2010; BERKOWITZ, 2001. Resulta inevitable, así, desde una perspectiva de la historia de la filosofía, citar lo enseñado por máximos teóricos políticos, si queremos comprender por qué la imagen educativa antigua resulta problemática y no del todo satisfactoria para los estados democráticos de hoy. Sin duda la educación ha sido responsable de la formación del carácter y de la opinión de las personas.

Needless to say, the power of education in forming people’s character and opinions is widely recognized. Nonetheless, by looking at the history of the institution, it seems obvious that its purpose is not only to form habits but to circumscribe the knowledge of the persons in such a way as to

  1. The influence of life history and sexual dimorphism on entheseal changes in modern humans and African great apes.

    Directory of Open Access Journals (Sweden)

    Marco Milella

    Full Text Available Entheseal changes have been widely studied with regard to their correlation to biomechanical stress and their usefulness for biocultural reconstructions. However, anthropological and medical studies have demonstrated the marked influence of both age and sex on the development of these features. Studies of entheseal changes are mostly aimed in testing functional hypotheses and are mostly focused on modern humans, with few data available for non-human primates. The lack of comparative studies on the effect of age and sex on entheseal changes represent a gap in our understanding of the evolutionary basis of both development and degeneration of the human musculoskeletal system. The aim of the present work is to compare age trajectories and patterns of sexual dimorphism in entheseal changes between modern humans and African great apes. To this end we analyzed 23 postcranial entheses in a human contemporary identified skeletal collection (N = 484 and compared the results with those obtained from the analysis of Pan (N = 50 and Gorilla (N = 47 skeletal specimens. Results highlight taxon-specific age trajectories possibly linked to differences in life history schedules and phyletic relationships. Robusticity trajectories separate Pan and modern humans from Gorilla, whereas enthesopathic patterns are unique in modern humans and possibly linked to their extended potential lifespan. Comparisons between sexes evidence a decreasing dimorphism in robusticity from Gorilla, to modern humans to Pan, which is likely linked to the role played by size, lifespan and physical activity on robusticity development. The present study confirms previous hypotheses on the possible relevance of EC in the study of life history, pointing moreover to their usefulness in evolutionary studies.

    2011-01-01

    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 A.D., the "lion horoscope," and the Star of Bethlehem. Explori...

    Although sheep (Ovis aries) have been one of the most exploited domestic animals in Estonia since the Late Bronze Age, relatively little is known about their genetic history. Here, we explore temporal changes in Estonian sheep populations and their mitochondrial genetic diversity over the last 3000 years. We target a 558 base pair fragment of the mitochondrial hypervariable region in 115 ancient sheep from 71 sites in Estonia (c. 1200 BC–AD 1900s), 19 ancient samples from Latvia, Russia, Poland and Greece (6800 BC–AD 1700), as well as 44 samples of modern Kihnu native sheep breed. Our analyses revealed: (1) 49 mitochondrial haplotypes, associated with sheep haplogroups A and B; (2) high haplotype diversity in Estonian ancient sheep; (3) continuity in mtDNA haplotypes through time; (4) possible population expansion during the first centuries of the Middle Ages (associated with the establishment of the new power regime related to 13th century crusades); (5) significant difference in genetic diversity between ancient populations and modern native sheep, in agreement with the beginning of large-scale breeding in the 19th century and population decline in local sheep. Overall, our results suggest that in spite of the observed fluctuations in ancient sheep populations, and changes in the natural and historical conditions, the utilisation of local sheep has been constant in the territory of Estonia, displaying matrilineal continuity from the Middle Bronze Age through the Modern Period, and into modern native sheep.

    Radiocarbon dating would not have been possible if 14 C had not had the 'wrong' half-life - a fact that delayed its discovery. Following the discovery of this 5730 year radionuclide in laboratory experiments by Ruben and Kamen, it became clear to W. F. Libby that 14 C should exist in nature, and that it could serve as a quantitative means for dating artifacts and events marking the history of civilization. The search for natural radiocarbon was a metrological challenge; the level in the living biosphere (ca. 230 Bq/kg) lay far beyond the then current state of the measurement art. This article traces the metrological history of radiocarbon, from the initial breakthrough devised by Libby, to minor (evolutionary) and major (revolutionary) advances that have brought 14 C measurement from a crude, bulk (8 g carbon) dating tool, to a refined probe for dating tiny amounts of precious artifacts, and for 'molecular dating' at the 10 μg to 100 mg level. The metrological advances led to opportunities and surprises, such as the non-monotonic dendrochronological calibration curve and the 'bomb effect', that spawned new multidisciplinary areas of application, ranging from cosmic ray physics to oceanography to the reconstruction of environmental history.

    Full Text Available Ecosystem boundaries, such as the Arctic-Boreal treeline, are strongly coupled with climate and were spatially highly dynamic during past glacial-interglacial cycles. Only a few studies cover vegetation changes since the last interglacial, as most of the former landscapes are inundated and difficult to access. Using pollen analysis and sedimentary ancient DNA (sedaDNA metabarcoding, we reveal vegetation changes on Bol’shoy Lyakhovsky Island since the last interglacial from permafrost sediments. Last interglacial samples depict high levels of floral diversity with the presence of trees (Larix, Picea, Populus and shrubs (Alnus, Betula, Ribes, Cornus, Saliceae on the currently treeless island. After the Last Glacial Maximum, Larix re-colonised the island but disappeared along with most shrub taxa. This was probably caused by Holocene sea-level rise, which led to increased oceanic conditions on the island. Additionally, we applied two newly developed larch-specific chloroplast markers to evaluate their potential for tracking past population dynamics from environmental samples. The novel markers were successfully re-sequenced and exhibited two variants of each marker in last interglacial samples. SedaDNA can track vegetation changes as well as genetic changes across geographic space through time and can improve our understanding of past processes that shape modern patterns.

    There are several genetic diseases with a wide spectrum of congenital bone stigmata in association to cutaneous and visceral benign and malignant neoplasms. Gorlin-Goltz syndrome, also named nevoid basal cell carcinoma syndrome, is an autosomal dominant systemic disease with almost complete penetrance and high intra-familial phenotypic variability, caused by germline mutations of the gene PTCH1. The syndrome is characterized by unusual skeletal changes and high predisposition to the development of multiple basal cell carcinomas, odontogenic keratocysts tumors and other visceral tumors. The Gorlin syndrome, clinically defined as distinct syndrome in 1963, existed during Dynastic Egyptian times, as revealed by a costellation of skeletal findings compatible with the syndrome in mummies dating back to 3000years ago and, most likely, in the ancient population of Pompeii. These paleogenetic and historical evidences, together with the clinical and biomolecular modern evidences, confirm the quite benign behavior of the syndrome and the critical value of the multiple and synchronous skeletal anomalies in the recognition of these rare and complex genetic disease.

    Recent critical approaches to what has conventionally been described as "scientific" and "technical" knowledge in early modern Europe have provided a wealth of new insights. So far, the various analytical concepts suggested by these studies have not yet been comprehensively discussed. The present essay argues that such comprehensive approaches might prove of special value for long-term and cross-cultural reflections on technology-related knowledge. As heuristic tools, the notions of "formalization" and "interaction" are proposed as part of alternative narratives to those highlighting the emergence of "science" as the most relevant development for technology-related knowledge in early modern Europe.

    The history of kidney and urologic disorders dates back to the dawn of civilization. Throughout history of medicine, urine, the first bodily fluid to be examined, has continuously been studied as a means of understanding inner bodily function. The purpose of this review was to appraise the contributions of the ancient Iranian physician pioneers in the field of kidney and urological disorders, and to compare their beliefs and clinical methods with the modern medicine. We searched all available reliable electronic and published sources for the views of ancient Iranian physicians, Avicenna, Rhazes, Al-Akhawayni, and Jorjani, and compared them with recent medical literature. Our findings showed that ancient Iranian physicians described the symptoms, signs, and treatment of kidney and urological disorders; addressed bladder anatomy and physiology; and performed bladder catheterization and stone removal procedures in accordance with contemporary medicine. Ancient Iranian physicians pursued a comprehensive scientific methodology based on experiment, which is in compliance with the bases of modern medicine.

    Antibiotic resistance is an ancient biological mechanism in bacteria, although its proliferation in our contemporary world has been amplified through antimicrobial therapy. Recent studies conducted on ancient environmental and human samples have uncovered numerous antibiotic-resistant bacteria and resistance genes. The resistance genes that have been reported from the analysis of ancient bacterial DNA include genes coding for several classes of antibiotics, such as glycopeptides, β-lactams, tetracyclines, and macrolides. The investigation of the resistome of ancient bacteria is a recent and emerging field of research, and technological advancements such as next-generation sequencing will further contribute to its growth. It is hoped that the knowledge gained from this research will help us to better understand the evolution of antibiotic resistance genes and will also be used in drug design as a proactive measure against antibiotic resistance.

The record of their publications prove, contrary to common stereotypes on the permanent conflict between science and religion, that they all embraced Modern, anti-Aristotelian, natural philosophy fairly equally and unreservedly. The rhetoric they used in manuscript Dedications to prospective patrons also show that they were actively engaged in shifting Modern science from a context of private consumption to one of public circulation. I acknowledgethat the dissemination of Modern science in Portugal during the 1700’s was slow and protracted. This phenomenon, however, was not, as typically argued, caused by scientific conservatism on the part of the religious Orders, or the ill will of patrons of the sciences, but by the political motives of enlightened despots João V, José I and his Prime-Minister the Marquis of Pombal.

  18. The remarkable metrological history of 14C dating: from ancient Egyptian artifacts to particles of soot and grains of pollen

    International Nuclear Information System (INIS)

    Currie, L.A.

    2002-01-01

    Radiocarbon dating would not have been possible if 14 C had not had the 'wrong' half-life, a fact that delayed its discovery. Following the discovery of this 5730 year radionuclide in laboratory experiments by Ruben and Kamen, it became clear to Willard Libby that 14 C should exist in nature, and that it could serve as a quantitative means for dating artifacts and events marking the history of civilization. The search for natural radiocarbon was a metrological challenge; the level in the living biosphere [ca. 230 Bq/kg] lay far beyond the then current state of the measurement art. The metrological history of radiocarbon was traced from the initial breakthrough devised by Libby, to minor (evolutionary) and major (revolutionary) advances that brought 14 C measurement from a crude, bulk [8 g carbon] dating tool, to a refined probe for dating tiny amounts of precious artifacts, and for 'molecular dating' at the 10-100 μg level. The first metrological revolution resulted from a combination of a major improvement in the 14 C beta particle detection efficiency and consequent improvement in precision, and the new science of dendrochronology which extended the radiocarbon dating calibration curve to some 8000 years before present (BP). The fine structure of the calibration function revealed natural and anthropogenic variations in the 14 C content of living matter, contrary to one of the basic assumptions of radiocarbon dating. This 'failure' of radiocarbon dating, however, spawned new multidisciplinary areas of environmental and geoscience. The most notable of the anthropogenic variations was that induced by atmospheric nuclear testing. The 'bomb pulse' of the mid-1960s gave rise to a global atmospheric and marine tracer experiment, and its by-product was an additional, short-term 14 C 'decay curve' that has allowed the dating of late 20th Century artifacts to the nearest year or two. The second major advance came in 1977-78 when 'atom counting' of 14 C was developed

  19. History of a modern place: Clorindo Testa and the Santa Rosa Civic Center, La Pampa

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Santa Rosa, capital of the young province of La Pampa, was founded in 1892 at the end of the military campaigns that annihilated the indigenous people and ensured republican control over the Patagonia region. In 1955, the city held a design competition for the construction of its Civic Center. This was not a current infill operation intended to renew the core of the city, since it was not just a matter of raising a new facade along one of the four sides of the main square. The task implied designing, almost from scratch, a new part of city. Competitors were supposed to organize new buildings and public spaces within an area of nine hectares standing between the existing city and the surrounding pampas. Clorindo Testa won the competition by proposing that it be built as a piece of a modern city. Situated in the middle of Argentinean pampas, the Santa Rosa Civic Center has been less extensively discussed than other of Testa’s great contemporary works, such as the London Bank (1959 and the National Library (1962, both in Buenos Aires, even in the South American context. The Government Building, the Bus Station and the covered central space were built before 1963. Testa finished the Legislature Building in 1976, and even though in 2006 he was able to conclude the little Legislature Library, half of the Civic Center area still remains as open space. Nevertheless, as a living piece of the never-completed modern project installed in the far south, La Pampa’s case seems to pose relevant urban questions. This paper explores the case from two complementary perspectives. One focuses on the results of the first competition, recognizing an original contribution to the relationship between modernity, monument, and place. The second discusses the unfinished condition of the Civic Center as constitutive to modern tradition in the very modern sense of the city as a never-completed work.

    Understanding the demographic history of a population is critical to conservation and to our broader understanding of evolutionary processes. For many tropical large mammals, however, this aim is confounded by the absence of fossil material and by the misleading signal obtained from genetic data of recently fragmented and isolated populations. This is particularly true for the lion which as a consequence of millennia of human persecution, has large gaps in its natural distribution and several recently extinct populations. We sequenced mitochondrial DNA from museum-preserved individuals, including the extinct Barbary lion (Panthera leo leo) and Iranian lion (P. l. persica), as well as lions from West and Central Africa. We added these to a broader sample of lion sequences, resulting in a data set spanning the historical range of lions. Our Bayesian phylogeographical analyses provide evidence for highly supported, reciprocally monophyletic lion clades. Using a molecular clock, we estimated that recent lion lineages began to diverge in the Late Pleistocene. Expanding equatorial rainforest probably separated lions in South and East Africa from other populations. West African lions then expanded into Central Africa during periods of rainforest contraction. Lastly, we found evidence of two separate incursions into Asia from North Africa, first into India and later into the Middle East. We have identified deep, well-supported splits within the mitochondrial phylogeny of African lions, arguing for recognition of some regional populations as worthy of independent conservation. More morphological and nuclear DNA data are now needed to test these subdivisions.

    One specific mutation of the GJB2 gene that encodes the connexin 26 protein, the 35delG mutation, has become a major interest among scientists who focus on the genetics of nonsyndromic hearing loss. The mutation accounts for the majority of GJB2 mutations detected in Caucasian populations and represents one of the most frequent disease mutations identified so far. The debate was so far between the arguments whether or not the 35delG mutation constitutes a mutational hot-spot or a founder effect; however, it was recently clarified that the latter seems the most likely. In an attempt to explore the origin and propagation of the 35delG mutation, several groups have reported the prevalence of the mutation and the carrier rates in different populations worldwide. It is now certain that the theory of a common founder prevails and that the highest carrier frequencies of the 35delG mutation are observed in southern European populations, giving rise to a discussion regarding the origin of the 35delG mutation. In this study, we discuss data previously published by our and other groups and also compare the haplotype distribution of the mutation in southern Europe, trying to understand the pathways of science and history and the conflict between them.

  3. A brief history of 'lone' atrial fibrillation: from 'a peculiar pulse irregularity' to a modern public health concern.

    Potpara, Tatjana S; Lip, Gregory Y H

    2015-01-01

    Ever since the original description of a 'peculiar pulse irregularity', atrial fibrillation (AF) has been studied extensively and has come a long journey from the recognition of its cardiac origins, to the modern concept of AF as a serious public health challenge with profound social and economic implications. This arrhythmia affects around 2% of adult population, and the most common underlying heart diseases accompanying AF in the modern era are hypertension, heart failure and coronary artery disease, as well as valvular heart diseases and numerous other cardiac as well as non-cardiac disorders which have been shown to predispose to AF. On occasions, AF occurs in young otherwise apparently healthy individuals (so called 'lone AF'). For a long time, 'lone' AF has been believed to bear a favourable prognosis as compared to AF with underlying structural heart disease, but increasing evidence suggests that 'lone' AF patients represent a rather heterogeneous cohort, with highly variable individual risk profiles due to the presence of various subclinical cardiovascular risk factors or genetically determined subtle alterations at the cellular or molecular level. For these reasons, the existence of truly 'lone' AF has recently been questioned. In this review article, we present a brief history of the recognition of the public health burden of AF. We discuss some of the misconceptions and breakthroughs on modern knowledge on AF, including the rise (and fall) of the 'lone' AF concept.

  8. Insights into Ancient Human Populations and their Environment through Stable Isotope Analysis

    Fundamental to the understanding of human history is the ability to make interpretations based on artifacts and other remains which are used to gather information about an ancient population. Sequestered in the organic matrices of these remains can be information concerning incidence of disease, population interactions, genetic defects and diet. Stable isotopes have long been used to interpret diet and trophic interactions in modern ecosystems. We suggest that the isotope compositions of a commonly overlooked material, human hair, is an ideal tool to be used in gleaning information, especially on human diets, about ancient civilizations. Hair can be well-preserved and is amenable to routine measurements of 13C, 15N and 34S isotope analyses and distinguishing sources of nutrition. We have isotopically characterized hair from both modern and ancient individuals. There is a wide diversity in isotope values owing, at least partially, to the levels of seafood, corn-fed animals and other grains in diet. Using these isotope tracers, new information regarding historical figures (George Washington, 1799 AD) to perhaps the most ancient of mummies, the Chinchorro of Chile (more than 7000 BP) as well as the Moche of Peru (1500 BP) and the best preserved mummy, the Neolithic Ice Man of the Oetztaler Alps (5200 BP), have been deciphered. It appears that the often-overlooked hair in archaeological sites represents a significant approach for understanding ancient human communities and their environments, as well as new perspectives on our use of our own modern nutritional sources.

  11. Abraham Pais Prize Lecture: Shifting Problems and Boundaries in the History of Modern Physics

    Science.gov (United States)

    Nye, Mary-Jo

    A long established category of study in the history of science is the ``history of physical sciences.'' It is a category that immediately begs the question of disciplinary boundaries for the problems and subjects addressed in historical inquiry. As a historian of the physical sciences, I often have puzzled over disciplinary boundaries and the means used to create or justify them. Scientists most often have been professionally identified with specific institutionalized fields since the late 19th century, but the questions they ask and the problems they solve are not neatly carved up by disciplinary perimeters. Like institutional departments or professorships, the Nobel Prizes in the 20th century often have delineated the scope of ``Physics'' or ``Chemistry'' (and ``Physiology or Medicine''), but the Prizes do not reflect disciplinary rigidity, despite some standard core subjects. In this paper I examine trends in Nobel Prize awards that indicate shifts in problem solving and in boundaries in twentieth century physics, tying those developments to changing themes in the history of physics and physical science in recent decades.

    Harold Neuhof was one of the pioneers of thoracic surgery in the early decades of the last century. Inspired by his preceptor Howard Lilienthal he proposed an entirely new concept for surgery on acute lung abscess. The aim of his one-stage procedure was adequate drainage of the abscess cavity. His approach proved to be the first major breakthrough in the treatment of acute lung abscess. Therapy of pulmonary abscess was again radically changed by the advent of antibiotics in the late 1940s. However, the basic principles of Neuhof's concept still influence modern-day management of putrid lung abscess. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Shrikant Deshpande

    2014-01-01

    Full Text Available This article describes the history and various milestones of rheumatology from ancient to modern times. The origin of rheumatology can be traced to ancient times. Diseases such as gout and osteoarthritis were prevalent in ancient people. Many ancient skeletons show signs of gout and osteoarthritis. The ancient book on Indian Medicine, Charaka Samhita, gives a vivid description of many variants of arthritis. Charaka, an eminent Ayurvedic physician, described rheumatoid arthritis (RA in Charaka Samhitha as "Vishkantha," meaning painful joints. The word rheumatology has its origin in the word "rheuma," which means flowing, and is mentioned in Hippocratic corpus. Hippocrates made several observations about gout, popularly known as "aphorisms of gout." Many famous paintings in the medieval era depict joint diseases. Hand lesions resembling those of RA are found in paintings of the Flemish school. "The virgin with canon van der paele," a painting by Jan Van Eyck (1436, shows thickened arteries in the temple, suggestive of temporal arthritis. The famous portrait of Federigo de Montefeltre, thought to have been painted by Joos (Justus van Gent, shows arthritis of the proximal interphalangeal joint of the left index finger. Rheumatology developed as a well-recognized specialty of medicine in the 20th century. American Physicians Bernard Comroe and Joseph Lee Hollander coined the term rheumatologist in 1940. Rheumatology has rapidly advanced during the last 50 years due to improved diagnosis as a result of progress in immunology, molecular biology, genetics and imaging.

  15. Connecting the Indies: the hispano-asian Pacific world in early Modern Global History

    Directory of Open Access Journals (Sweden)

    Ryan Dominic Crewe

    Full Text Available Abstract This article reconsiders the place of colonial Latin America in global history by examining the Transpacific interactions, conflicts, and exchanges between Latin America and Asia in the sixteenth and seventeenth centuries. Setting aside earlier imperial histories that present the Pacific as a 'Spanish Lake', I conceptualize a dynamic Hispano-Asian Pacific World that was forged by a myriad of actors in and around the Pacific basin. Instead of a Pacific dominated by far-off Spain, my research reveals a Transpacific world that in fact defied imperial efforts to claim, regulate, or convert it. I structure this study along three broad lines of inquiry: the economic ties that made the Asian-Latin American 'Rim', the consequences of human transits and cultural exchanges along new Transpacific conduits, and the barriers of distance and culture that limited both cosmopolitanism and imperialism. For societies in Latin America, this Hispano-Asian Pacific world provided them with greater autonomy than the Atlantic world. They shared, alongside diverse groups in this maritime world, a common story of circumvention, of freewheeling exchanges, and of checked powers, for no single shoreline, empire, or group predominated. Ultimately, by charting the currents of Hispano-Asian interactions in the Pacific world, I provide a riposte to theories in global historiography that have situated Latin America at the periphery of Western Europe.

    Full Text Available The article is devoted to urgent problems of demographic development of rural areas, their impact on socioeconomic processes at all levels of the national economic system. The content of demographic and economic antonyms of «demographic development» and «demographic catastrophe» has been characterized. The article analyzes the historical background of demographic change in rural areas, their socio-economic consequences. It’s reasonably concluded that the economic development of Ukraine requires urgent settlement of the negative socio-demographic trends that are characteristic for a Ukrainian village. Nowadays, these trends are of a destructive nature. They lead to a protracted crisis of agricultural production which is very difficult to overcome solely with the tools of technical and technological modernization. This will complicate the food security of the state for many years; lower the level and quality of life of the population, lead to greater territorial disparities and degradation of rural areas and the marginalization of residents of Ukrainian villages.

    2011-01-01

    The Minnesota River Valley was carved during catastrophic drainage of glacial Lake Agassiz at the end of the late Pleistocene. The ensuing base-level drop on tributaries created knickpoints that excavated deep valleys as they migrated upstream. A sediment budget compiled in one of these tributaries, the Le Sueur River, shows that these deep valleys are now the primary source of sediment to the Minnesota River. To compare modern sediment loads with pre-European settlement erosion rates, we analyzed incision history using fluvial terrace ages to constrain a valley incision model. Results indicate that even thoughthe dominant sediment sources are derived from natural sources (bluffs, ravines, and streambanks), erosion rates have increased substantially, due in part to pervasive changes in watershed hydrology.

  18. A highly variable segment of human subterminal 16p reveals a history of population growth for modern humans outside Africa

    Science.gov (United States)

    Alonso, Santos; Armour, John A. L.

    2001-01-01

    We have sequenced a highly polymorphic subterminal noncoding region from human chromosome 16p13.3, flanking the 5′ end of the hypervariable minisatellite MS205, in 100 chromosomes sampled from different African and Euroasiatic populations. Coalescence analysis indicates that the time to the most recent common ancestor (approximately 1 million years) predates the appearance of anatomically modern human forms. The root of the network describing this variability lies in Africa. African populations show a greater level of diversity and deeper branches. Most Euroasiatic variability seems to have been generated after a recent out-of-Africa range expansion. A history of population growth is the most likely scenario for the Euroasiatic populations. This pattern of nuclear variability can be reconciled with inferences based on mitochondrial DNA. PMID:11158547

    Directory of Open Access Journals (Sweden)

    E.A. Lalla

    2016-07-01

    Full Text Available A detailed vibrational Raman-IR spectroscopic and diffractional analyses have been performed on basalts from two locations from Tenerife Island: (1 the Arenas Negras volcano which belongs to the historical eruption not showing visible alteration and (2 Pillow Lavas zone from Anaga Massif which shows a clearly fluid-rock interaction caused by submarine alteration. These places have been extensively studied due to its similarity with the surface of Mars. The analysis is based on the mineral detection of selected samples by a Micro-Raman study of the materials. The complementary techniques have confirmed the mineralogy detected by the Raman measurement. The results show a volcanic environment behavior with primary phases like olivine, pyroxene, and feldspar/plagioclase. Moreover, the presence of accessory minerals or secondary mineralization like phosphate, iron oxides, zeolite or carbonates shows the alteration processes on each outcrop. The variation in the crystallinity and amorphous phases is related to fluid-rock interaction caused by hydrothermal episodes and external weathering processes, which shows several analogies with the ancient volcanic activity from Mars.

    Chew Bahir is a tectonic basin in the southern Ethiopian Rift, close to the Lower Omo valley, site of earliest known fossil of anatomically modern humans. It was drilled in Nov-Dec 2014 as part of the Hominin Sites and Paleolakes Drilling Project (HSPDP) and the Collaborative Research Center (CRC806) "Our Way to Europe". Two overlapping cores of mostly clayey silts, reaching a composite depths of 280m, were collected and may cover the last 500,000 years, thus providing a potential record of environmental history during the evolution and spread of anatomically modern humans. Here we present the lithology and stratigraphy of the composite core as well as results of high resolution MSCL and XRF scanning data. Initial sedimentological and geochemical results show that the Chew Bahir deposits are a sensitive record of changes in moisture, sediment influx, provenance, transport and diagenetic processes, evident from mineralogy, elemental concentration and physical properties. The potassium record is highly sensitive to changes in moisture balance (Foerster et al. 2015). XRF and XRD data suggest that the process linking climate with potassium concentrations is the diagenetic illitization of smectites during dry episodes with high alkalinity and salinity in the closed-basin lake. The core records will allow tests of the various hypotheses about the influence of environmental change on the evolution and dispersal of anatomically modern humans.

Specifically, we used coalescence modelling to estimate population size and fluctuations from the sequence diversity at the cytochrome b (cytb) and Pantophysin I (PanI) loci. The models are consistent with an expanding population during the warm medieval period, large historical effective population size (NE), a marked bottleneck event at 1400-1500 and a decrease in NE in early modern times. The model results are corroborated by the reduction of haplotype and nucleotide variation over time and pairwise population distance as a significant portion of nucleotide variation partitioned across the 1550 time mark. The mean age of the historical fished stock is high in medieval times with a truncation in age in early modern times. The population size crash coincides with a period of known cooling in the North Atlantic, and we conclude that the collapse may be related to climate or climate-induced ecosystem change.

    Attention-deficit hyperactivity disorder (ADHD) is a complex, heterogeneous and multifactorial neurodevelopmental disorder characterized by persistent symptoms of inattention, hyperactivity and impulsivity. Although the first clinical description of a constellation of symptoms highly resembling to what currently could be diagnosed as ADHD is generally attributed to George F Still in 1902, there are scattered but significant published historical medical, scientific and non-scientific reports, much prior to Still’s lectures, of what is currently conceptualized as ADHD. The present report aimed at exploring the early history of ADHD, prior to the 20th century in the medical literature and in other historical sources, to provide clinicians, researchers and other professionals with a better understanding of the roots and current conceptualization of this disorder. It is possible to find clues and highly suggestive descriptions of individuals presenting symptoms resembling what is currently defined as ADHD in the literature, in paintings or in the Bible. However, the earliest medical reports of individuals with abnormal degrees of inattention, distractibility and overactivity date from the last quarter of the 18th century, included in two of the first textbooks specifically on the subject of mental diseases, published by the German Melchior Adam Weikard and the Scottish Sir Alexander Crichton. During the 19th century some eminent physicians from Germany, France or Great Britain, such as Charles West, Thomas C Albutt, Thomas S Clouston, William W, Ireland, John Haslam, Heinrich Neumann, or Désiré-Magloire Bourneville, among others provided clinical depictions of patients that most likely presently would be diagnosed as having ADHD. Whilst some of the children described by Still and his predecessors may have suffered from a variety of neurological and psychiatric disorders, many of these patients showed clear symptoms of ADHD and may present with comorbid disorders, as

  8. History of Modern Earthquake Hazard Mapping and Assessment in California Using a Deterministic or Scenario Approach

    Modern earthquake ground motion hazard mapping in California began following the 1971 San Fernando earthquake in the Los Angeles metropolitan area of southern California. Earthquake hazard assessment followed a traditional approach, later called Deterministic Seismic Hazard Analysis (DSHA) in order to distinguish it from the newer Probabilistic Seismic Hazard Analysis (PSHA). In DSHA, seismic hazard in the event of the Maximum Credible Earthquake (MCE) magnitude from each of the known seismogenic faults within and near the state are assessed. The likely occurrence of the MCE has been assumed qualitatively by using late Quaternary and younger faults that are presumed to be seismogenic, but not when or within what time intervals MCE may occur. MCE is the largest or upper-bound potential earthquake in moment magnitude, and it supersedes and automatically considers all other possible earthquakes on that fault. That moment magnitude is used for estimating ground motions by applying it to empirical attenuation relationships, and for calculating ground motions as in neo-DSHA (Z uccolo et al., 2008). The first deterministic California earthquake hazard map was published in 1974 by the California Division of Mines and Geology (CDMG) which has been called the California Geological Survey (CGS) since 2002, using the best available fault information and ground motion attenuation relationships at that time. The California Department of Transportation (Caltrans) later assumed responsibility for printing the refined and updated peak acceleration contour maps which were heavily utilized by geologists, seismologists, and engineers for many years. Some engineers involved in the siting process of large important projects, for example, dams and nuclear power plants, continued to challenge the map(s). The second edition map was completed in 1985 incorporating more faults, improving MCE's estimation method, and using new ground motion attenuation relationships from the latest published

    Full Text Available Literatures concerning the history of West African peoples published from 1900 to 1970 debate�the possible migrations of the Egyptians into West Africa. Writers like Samuel Johnson and�Lucas Olumide believe that the ancient Egyptians penetrated through ancient Nigeria but Leo�Frobenius and Geoffrey Parrinder frowned at this opinion. Using the works of these early�20th century writers of West African history together with a Yoruba legend which teaches�about the origin of their earliest ancestor(s, this researcher investigates the theories that the�ancient Egyptians had contact with the ancient Nigerians and particularly with the Yorubas.Intradisciplinary and/or interdisciplinary implications: There is an existing ideology�amongst the Yorubas and other writers of Yoruba history that the original ancestors of�the Yorubas originated in ancient Egypt hence there was migration between Egypt and�Yorubaland. This researcher contends that even if there was migration between Egypt and�Nigeria, such migration did not take place during the predynastic and dynastic period as�speculated by some scholars.

    Full Text Available Before analysis of DNA from ancient remains was possible, anthropologists studied evolution and migration patterns using data obtained from population genetic studies on modern populations combined with data obtained from morphological evaluations of ancient remains. Currently, DNA analysis of ancient populations is making a valuable contribution to these efforts. Researchers that perform ancient DNA analysis prefer to study polymorphisms on the Y chromosome or mitochondrial DNA because the results are easier to statistically evaluate. To evaluate polymorphisms on diploid genomes, which are more informative, only mutations that have been extensively examined in modern populations should be chosen. The most extensively evaluated mutations are those related to prevalent inherited disorders. As such, beta-thalassemia, sickle cell anemia, FVL mutation of globin and the factor V genes are good candidates for DNA studies in ancient populations. These mutations are common in Anatolia, host to many civilizations since the Paleolithic period. This history makes Anatolia a good place for conducting research that could enhance our understanding of human evolution and migration patterns.

Despite such remarkable species diversity and ubiquity, the evolutionary history of this major freshwater fish clade, Otophysi, remains largely unexplored. To gain insight into the history of otophysan diversification, we constructed a timetree based on whole mitogenome sequences across 110 species representing 55 of the 64 families.

  14. Analysis of a Modern Hybrid and an Ancient Sugarcane Implicates a Complex Interplay of Factors in Affecting Recalcitrance to Cellulosic Ethanol Production.

    Directory of Open Access Journals (Sweden)

    Viviane Guzzo de Carli Poelking

    Full Text Available Abundant evidence exists to support a role for lignin as an important element in biomass recalcitrance. However, several independent studies have also shown that factors apart from lignin are also relevant and overall, the relative importance of different recalcitrance traits remains in dispute. In this study we used two genetically distant sugarcane genotypes, and performed a correlational study with the variation in anatomical parameters, cell wall composition, and recalcitrance factors between these genotypes. In addition we also tracked alterations in these characteristics in internodes at different stages of development. Significant differences in the development of the culm between the genotypes were associated with clear differential distributions of lignin content and composition that were not correlated with saccharification and fermentation yield. Given the strong influence of the environment on lignin content and composition, we hypothesized that sampling within a single plant could allow us to more easily interpret recalcitrance and changes in lignin biosynthesis than analysing variations between different genotypes with extensive changes in plant morphology and culm anatomy. The syringyl/guaiacyl (S/G ratio was higher in the oldest internode of the modern genotype, but S/G ratio was not correlated with enzymatic hydrolysis yield nor fermentation efficiency. Curiously we observed a strong positive correlation between ferulate ester level and cellulose conversion efficiency. Together, these data support the hypothesis that biomass enzymatic hydrolysis recalcitrance is governed by a quantitative heritage rather than a single trait.

    During the first decades of the 20th century, many anthropologists who had previously adhered to a linear view of human evolution, from an ape via Pithecanthropus erectus (today Homo erectus) and Neanderthal to modern humans, began to change their outlook. A shift towards a branching model of human evolution began to take hold. Among the scientific factors motivating this trend was the insight that mammalian evolution in general was best represented by a branching tree, rather than by a straight line, and that several new fossil hominids were discovered that differed significantly in their morphology but seemed to date from about the same period. The ideological and practical implications of imperialism and WWI have also been identified as formative of the new evolutionary scenarios in which racial conflict played a crucial role. The paper will illustrate this general shift in anthropological theory for one particular scientist, William Sollas (1849-1936). Sollas achieved a synthesis of human morphological and cultural evolution in what I will refer to as an imperialist model. In this theoretical framework, migration, conflict, and replacement became the main mechanisms for progress spurred by 'nature's tyrant,' natural selection.

  16. Glacial history of a modern invader: phylogeography and species distribution modelling of the Asian tiger mosquito Aedes albopictus.

    Directory of Open Access Journals (Sweden)

    Daniele Porretta

    Full Text Available BACKGROUND: The tiger mosquito, Aedes albopictus, is one of the 100 most invasive species in the world and a vector of human diseases. In the last 30 years, it has spread from its native range in East Asia to Africa, Europe, and the Americas. Although this modern invasion has been the focus of many studies, the history of the species' native populations remains poorly understood. Here, we aimed to assess the role of Pleistocene climatic changes in shaping the current distribution of the species in its native range. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the phylogeography, historical demography, and species distribution of Ae. albopictus native populations at the Last Glacial Maximum (LGM. Individuals from 16 localities from East Asia were analyzed for sequence variation at two mitochondrial genes. No phylogeographic structure was observed across the study area. Demographic analyses showed a signature of population expansion that started roughly 70,000 years BP. The occurrence of a continuous and climatically suitable area comprising Southeast China, Indochinese Peninsula, and Sundaland during LGM was indicated by species distribution modelling. CONCLUSIONS/SIGNIFICANCE: Our results suggest an evolutionary scenario in which, during the last glacial phase, Ae. albopictus did not experience a fragmentation phase but rather persisted in interconnected populations and experienced demographic growth. The wide ecological flexibility of the species probably played a crucial role in its response to glacial-induced environmental changes. Currently, there is little information on the impact of Pleistocene climatic changes on animal species in East Asia. Most of the studies focused on forest-associated species and suggested cycles of glacial fragmentation and post-glacial expansion. The case of Ae. albopictus, which exhibits a pattern not previously observed in the study area, adds an important piece to our understanding of the Pleistocene history

    Fe-oxyhydroxide sediments (gossans) from the Ashadze-2 hydrothermal sulfide field (Mid-Atlantic Ridge) and hematite-carbonate-quartz rocks (gossanites) from the Yubileynoe Cu-Zn VHMS deposit (South Urals) are characterized by anomalously high U contents (up to 352 ppm and 73 ppm, respectively). In gossans from the Ashadze-2 hydrothermal sulfide field, rare isometric anhedral uraninite grains (up to 2 μm) with outer P- and Ca-rich rims, and numerous smaller (<1 μm) grains, occur in Fe-oxyhydroxides and sepiolite, associated with pyrite, isocubanite, chalcopyrite, galena, atacamite and halite. In gossanites from the Yubileynoe deposit, numerous uraninite particles (<3 μm) are associated with apatite, V-rich Mg-chlorite, micro-nodules of pyrite, Se-bearing galena, hessite and acanthite in a hematite-carbonate-quartz matrix. Small (1-3 μm) round grains of uraninite, which locally coalesce to large grains up to 10 μm in size, are associated with authigenic chalcopyrite. The similar diagenetic processes of U accumulation in modern and ancient Fe-oxyhydroxide sediments were the result of U fixation from seawater during the oxidation of sulfide minerals. Uraninite in gossanites was mainly deposited from diagenetic pore fluids, which circulated in the sulfide-hyaloclast-carbonate sediments.

    To grasp the three-dimensional structure of ancient tomb during the archaeological prospecting of Kaibukiyama ancient tomb, various electrical resistivity methods were tried. For the survey, firstly, in order to clarify the electrical resistivity structure of rear circular part of ancient tomb, roughly, mapping was conducted by means of two-electrode method using a multi-channel measuring system. Then, the vertical prospecting was conducted densely with a mesh form having VES intervals of 2 m as a detailed survey by means of Schlumberger method. For the three-dimensional inverse analysis of apparent electrical resistivity data by the two-electrode method, a program with high calculation speed was developed by using algorithm where Jacobian with a homogeneous model is adopted for the Jacobian calculation. As a result of the analysis, an outline of underground 3-D resistivity structure was determined. The resistivity anomaly with high values obtained from the results of 2-D inverse analysis of VES curve by means of Schlumberger method agreed well with the central part of the ancient tomb, which was confirmed during the archaeological survey. 4 refs., 8 figs.

  20. A protocol for pressurized liquid extraction and processing methods to isolate modern and ancient bone cholesterol for compound-specific stable isotope analysis.

    Bone lipid compound-specific isotope analysis (CSIA) and bone collagen and apatite stable isotope ratio analysis are important sources of ecological and paleodietary information. Pressurized liquid extraction (PLE) is quicker and utilizes less solvent than traditional methods of lipid extraction such as soxhlet and ultrasonication. This study facilitates dietary analysis by optimizing and testing a standardized methodology for PLE of bone cholesterol. Modern and archaeological bones were extracted by PLE using varied temperatures, solvent solutions, and sample weights. The efficiency of PLE was assessed via quantification of cholesterol yields. Stable isotopic ratio integrity was evaluated by comparing isotopic signatures (δ 13 C and δ 18 O values) of cholesterol derived from whole bone, bone collagen and bone apatite. Gas chromatography/mass spectrometry (GC/MS) and gas chromatography isotope ratio mass spectrometry (GC/IRMS) were conducted on purified collagen and lipid extracts to assess isotopic responses to PLE. Lipid yield was optimized at two PLE extraction cycles of 75 °C using dichloromethane/methanol (2:1 v/v) as a solvent with 0.25-0.75 g bone sample. Following lipid extraction, saponification combined with the derivatization of the neutral fraction using trimethylsilylation yielded nearly twice the cholesterol of non-saponified or non-derivatized samples. It was also found that lipids extracted from purified bone collagen and apatite could be used for cholesterol CSIA. There was no difference in the bulk δ 13 C values of collagen extracted from bone with or without lipid. However, there was a significant depletion in 18 O of bone apatite due to lipid presence or processing. These results should assist sample selection and provide an effective, alternative extraction method for bone cholesterol that may be used for isotopic and paleodietary analysis.

    Travertine-precipitating springs and travertine deposits of the Colorado Plateau serve as natural analogues for evaluating potential leakage associated with geologic sequestration of carbon dioxide (CO2). Extensive Quaternary and modern travertine deposits occur along the Jemez lineament and Rio Grande rift in New Mexico and Arizona, and in the Paradox Basin in Utah, along the Little Grand Wash Fault and the Salt Wash Graben. These groundwater discharge deposits are interpreted to be sites of persistent and significant CO2 degassing along faults and above magmatic systems. Analysis of the geochemical and isotopic composition of U-series dated travertine deposits and modern travertine-precipitating waters allows evaluation of the flow paths of CO2-charged waters. Initial results from New Mexico and Arizona travertine deposits show characteristic rare earth element (REE) signatures for individual travertine deposits and yet generally overlap in concentrations of other trace elements such as Al, As, B, Ba, K, and Si. We report stable oxygen and carbon isotopes of the travertines in New Mexico, Arizona, and Utah. Different travertine deposits have different carbon-oxygen isotope variation patterns suggesting that these stable isotopes are tracers that have the ability to identify distinctive groundwater sources within and between spring groups based on the travertine record. Stable isotope analyses of travertine deposits in New Mexico and Arizona overlap substantially between deposits and cluster around -10‰ to -6‰ for δ18O and around 3.5‰ to 6.5‰ for δ13C. Travertine deposits in Utah show a distinctly different range of stable isotope values: δ18O values cluster around -14‰ to -10.5‰ and δ13C around 4.5‰ to 6.5‰. U-series dating of travertine deposits shows episodic travertine formation in New Mexico and Arizona over the last 700,000 years, and travertine accumulation over the last 400,000 years in Utah. We use U-series dating and volumetric

    Magnetic susceptibility is an increasingly popular low-cost method for rapidly assessing paleoclimate and paleoenvironmental impact on buried soils. The goal of this study is to determine the primary influence(s) on soil magnetic susceptibility along floodplain, terrace and upland soils in the middle Delaware River Valley, USA, using environmental magnetic, pedologic, and stratigraphic techniques. Two-hundred thirty samples were collected from age-constrained sandy, quartz-rich, floodplain, terrace, and upland soils (Entisols, Inceptisols). A Kruskal-Wallis (K-W) and post-hoc Tukey-Kramer (T-K) (α=0.05) multiple comparisons analysis on 176 mass-specific low-field susceptibility (Xlf) assays show that A and B horizons are magnetically enhanced compared to C and E horizons (ptesting show that Xlf results, when grouped by floodplain-terrace designation (i.e., chronofunction) are significantly different (p<0.0001). The older T3 terrace and upland Xlf values (0.34±0.14 10^-6 m^3 kg^-1) are greater than the younger T2 terrace (0.18±0.06 10^-6 m^3 kg^-1) values, which are greater than modern floodplain (0.09±0.01 10^-6 m^3 kg^-1) Xlf values. These data suggest that longer intervals of soil formation enhance the Χlf value. This hypothesis is further supported when 159 Xlf values are plotted vs. age for the entire Holocene. A locally-weighted regression smoothing curve (LOESS) shows two distinct intervals of magnetic enhancement during previously established dry intervals, the early and late-middle Holocene. We hypothesize that prolonged drought during the early and middle Holocene reduced flood frequency and magnitude and the likelihood of soil burial, resulting in longer soil forming intervals and higher Xlf values. Although precipitation influences the Xlf signature, the results from this study suggest that the magnetic susceptibility values of well-drained buried floodplain soils along the Delaware River Valley are partly a function of time.

  8. Modernity: Are Modern Times Different?

    Directory of Open Access Journals (Sweden)

    Lynn Hunt

    2014-12-01

    Full Text Available “Modernity” has recently been the subject of considerable discussion among historians. This article reviews some of the debates and argues that modernity is a problematic concept because it implies a complete rupture with “traditional” ways of life. Studies of key terms are undertaken with the aid of Google Ngrams. These show that “modernity,” “modern times,” and “traditional” —in English and other languages— have a history of their own. A brief analysis of the shift from a self oriented toward equilibrium to a self oriented toward stimulation demonstrates that modernity is not necessary to historical analysis.

  9. The Ninth Circuit Court's treatment of the history of suicide by Ancient Jews and Christians in Compassion in Dying v. State of Washington: historical naivete or special pleading?

    Science.gov (United States)

    Amundsen, D W

    1998-01-01

    In this article, Prof. Darrel Amundsen critiques Judge Reinhardt's comments regarding "Historical Attitudes Toward Suicide" in his Compassion in Dying opinion. Amundsen demonstrates that the court's characterization of ancient Jewish and Christian practices is inaccurate and misleading because it fails to acknowledge the complexities of the moral issue of suicide. Amundsen discusses martyrdom, suicide in general, suicide by the ill, and euthanasia in ancient Judaism. In contrast to the court's commentary, Amundsen demonstrates that regard for human life is a central feature of Jewish ethical monotheism. Furthermore, the author challenges the court's conclusions about early Christianity, and explains why its treatment of the issue of suicide in early Christianity is misleading and inaccurate. Amundsen's discussion of early Christianity includes suicide, martyrdom, and especially the Augustinian teaching on suicide. He concludes that the court's treatment of the issue of suicide in early Christianity is so historically and conceptually muddled as to be fundamentally inaccurate.

    An 84 base pair sequence of the Streptococcus mutans virulence factor, known as dextranase, has been obtained from 10 individuals from the Bronze Age to the Modern Era in Europe and from before and after the colonization in America. Modern samples show four polymorphic sites that have not been found in the ancient samples studied so far. The nucleotide and haplotype diversity of this region have increased over time, which could be reflecting the footprint of a population expansion. While this segment has apparently evolved according to neutral evolution, we have been able to detect one site that is under positive selection pressure both in present and past populations. This study is a first step to study the evolution of this microorganism, analysed using direct evidence obtained from ancient remains. PMID:25056622

    Developmental psychology is not only a psychology of development from childhood to old age but a psychology of human development in world history. Eighty years of cross-cultural empirical research findings indicate that the adolescent stage of formal operations evolved late in history and is not a universal development of adult humans across cultures and history. Correspondingly, preoperational or concrete operational stages describe adult psychological stages in past or premodern cultures, as Jean Piaget and some of his followers have mentioned. Developmental psychology is likewise a historical or anthropological psychology capable of describing humans in premodern cultures. The article develops a general anthropological or psychological theory answering the many questions that arise from the correspondences between (modern) children and ancient adults. On this psychological basis, the new structural genetic theory program is capable of explaining, better than previous approaches, the history of humankind from prehistory through ancient to modern societies, the history of economy, society, culture, religion, philosophy, sciences, morals, and everyday life. The accomplishment of this task was once demanded of some classical founders of psychology, sociology, history, and ethnology but was largely avoided by the postwar generations of authors for political and ideological reasons.

  12. Mechanisms in ancient Chinese books with illustrations

    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...

    that there were many reasons to suicide someone in antiquity. Very important factor was to avoid captivity and the consequent overcrowding of indignity, especially for politicians and military leaders. Also intention in these circumstances was to avoid torture and the disgrace of rape. Strong grief is another reason, as in case of death of family members. The erotic disappointment had place in ancient suicides, which concerned both men and women, while there were also suicide for financial reasons. Especially for the elderly, the despair of the anility in conjunction with physical illness and cachexia, were important factors for these people to decide thee suicidal. Finally, the methods of suicide fitted their epoch, but bear resemblance to those of the modern time. Poisoning was very common to both men and women but equally popular in both sexes was also the hanging. It was not unusual to fall from a high in order to reach the death, while stabbing a sword in the body for self killing was widespread in men and soldiers.

  14. Detecting Ancient Tuberculosis

    1998-12-01

    Full Text Available Some diseases have played a more significant role in human development than others. Here we describe the results of a trial to diagnose ancient tuberculosis using chemical methods. Palaeo-epidemiological studies of the disease are compromised, but it has become apparent that tuberculosis (TB is a 'population-density dependent' disease. From modern studies, it is also apparent that the prevalence of TB can be used as an indicator of the level of poverty within the studied population. Mid-shaft rib samples from articulated individuals recovered from the former Newcastle Infirmary Burial Ground (1753-1845 AD were examined for mycolic acids that are species-specific for Mycobacterium tuberculosis. The 24% of ribs positive for mycolic acids correlated with the documented 27% tuberculosis prevalence. Mycolic acid biomarkers have the potential to provide an accurate trace of the palaeo-epidemiology of tuberculosis in ancient populations, thereby providing an indication of the overall level of poverty - a useful adjunct for archaeology.

    2008-02-01

    Full Text Available Abstract The prehistory of African trypanosomiasis indicates that the disease may have been an important selective factor in the evolution of hominids. Ancient history and medieval history reveal that African trypanosomiasis affected the lives of people living in sub-Saharan African at all times. Modern history of African trypanosomiasis revolves around the identification of the causative agents and the mode of transmission of the infection, and the development of drugs for treatment and methods for control of the disease. From the recent history of sleeping sickness we can learn that the disease can be controlled but probably not be eradicated. Current history of human African trypanosomiasis has shown that the production of anti-sleeping sickness drugs is not always guaranteed, and therefore, new, better and cheaper drugs are urgently required.

    2015-12-01

    The use of coca leaf for medicinal purposes is a centuries-old tradition of the native peoples of South America. Coca products are thought by many laypersons to provide risk-free benefits to users participating in strenuous activities at high altitude. Physiologic studies of coca have increased understanding of its possible mechanism of action as well as its potential impact on high altitude activities. This present work explores the role of coca throughout the history of the Andean peoples and explores whether this ancient remedy has a place in modern medicine. A focused summary of research articles with particular relevance to the field of wilderness medicine is also included to better provide the reader with lessons not only from history but also from another culture.

  18. Ancient Chinese observations of physical phenomena attending solar eclipses

    International Nuclear Information System (INIS)

    Wang, P.K.; Siscoe, G.L.

    1980-01-01

    The realization that solar activity probably undergoes changes in qualitative character on time scales greater than the 11 or 22 year cycle but short compared to the duration of recorded history gives renewed importance to historical documents describing the state of solar activity. Modern eclipse observation reveal the presence of solar acitivity through the appearance of coronal structures and prominences. It has been widely remarked that eclipse records prior to the 18th century are uniformly silent on these conspicuous solar eclipse features, raising the possibility, however unlikely, that a change in solar activity has occurred which rendered them only recently noticeable. We present here material from ancient Chinese sources, primarily astrological, that describe phenomena attending solar eclipses that are almost certainly coronal structures and prominences. Thus, these aspects of the present character of solar activity have apparently occurred at other times in history, if not continuously. (orig.)

  1. Ancient fossil specimens of extinct species are genetically more distant to an outgroup than extant sister species are

    Science.gov (United States)

    Huang, Shi

    2009-01-01

    There exists a remarkable correlation between genetic distance as measured by protein or DNA dissimilarity and time of species divergence as inferred from fossil records. This observation has provoked the molecular clock hypothesis. However, data inconsistent with the hypothesis have steadily accumulated in recent years from studies of extant organisms. Here the published DNA and protein sequences from ancient fossil specimens were examined to see if they would support the molecular clock hypothesis. The hypothesis predicts that ancient specimens cannot be genetically more distant to an outgroup than extant sister species are. Also, two distinct ancient specimens cannot be genetically more distant than their extant sister species are. The findings here do not conform to these predictions. Neanderthals are more distant to chimpanzees and gorillas than modern humans are. Dinosaurs are more distant to frogs than extant birds are. Mastodons are more distant to opossums than other placental mammals are. The genetic distance between dinosaurs and mastodons is greater than that between extant birds and mammals. Therefore, while the molecular clock hypothesis is consistent with some data from extant organisms, it has yet to find support from ancient fossils. Far more damaging to the hypothesis than data from extant organisms, which merely question the constancy of mutation rate, the study of ancient fossil organisms here challenges for the first time the fundamental premise of modern evolution theory that genetic distances had always increased with time in the past history of life on Earth.

    Over the last decade, studies of ancient biomolecules-particularly ancient DNA, proteins, and lipids-have revolutionized our understanding of evolutionary history. Though initially fraught with many challenges, the field now stands on firm foundations. Researchers now successfully retrieve nucleotide and amino acid sequences, as well as lipid signatures, from progressively older samples, originating from geographic areas and depositional environments that, until recently, were regarded as hostile to long-term preservation of biomolecules. Sampling frequencies and the spatial and temporal scope of studies have also increased markedly, and with them the size and quality of the data sets generated. This progress has been made possible by continuous technical innovations in analytical methods, enhanced criteria for the selection of ancient samples, integrated experimental methods, and advanced computational approaches. Here, we discuss the history and current state of ancient biomolecule research, its applications to evolutionary inference, and future directions for this young and exciting field. Expected final online publication date for the Annual Review of Biochemistry Volume 87 is June 20, 2018. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    Science.gov (United States)

    Ahmed, Awad M

    2002-04-01

    Clinical features similar to diabetes mellitus were described 3000 years ago by the ancient Egyptians. The term "diabetes" was first coined by Araetus of Cappodocia (81-133AD). Later, the word mellitus (honey sweet) was added by Thomas Willis (Britain) in 1675 after rediscovering the sweetness of urine and blood of patients (first noticed by the ancient Indians). It was only in 1776 that Dobson (Britain) firstly confirmed the presence of excess sugar in urine and blood as a cause of their sweetness. In modern time, the history of diabetes coincided with the emergence of experimental medicine. An important milestone in the history of diabetes is the establishment of the role of the liver in glycogenesis, and the concept that diabetes is due to excess glucose production Claude Bernard (France) in 1857. The role of the pancreas in pathogenesis of diabetes was discovered by Mering and Minkowski (Austria) 1889. Later, this discovery constituted the basis of insulin isolation and clinical use by Banting and Best (Canada) in 1921. Trials to prepare an orally administrated hypoglycemic agent ended successfully by first marketing of tolbutamide and carbutamide in 1955. This report will also discuss the history of dietary management and acute and chronic complications of diabetes.

    Full Text Available Use of honey has a very long history. Honey has been used since ancient time due to its nutritional and therapeutic values. There had been varied ways of consumption honey including its use as a sweetener and flavoring agent. Honey is produced all over the world. The most important nutriment of honey is carbohydrates present in the form of monosaccharides, fructose and glucose. Honey plays an important role as an antioxidant, anti-inflammatory, anti-bacterial agent and augments the adherence of skin grafts and wound healing process. The role of honey has been acknowledged in the scientific literature and there is convincing evidence in support of its antioxidant and antibacterial nature, cough prevention, fertility and wound healing properties. However, its use has been controversially discussed and has not been well accepted in the modern medicine. The aim of this review was explore and highlight the role of honey in modern medicine.

    2011-12-01

    In order to study the genetic characteristics of the Lower Xiajiadian culture (LXC) population, a main bronze culture branch in northern China dated 4500-3500 years ago, two uniparentally inherited markers, mitochondrial DNA and Y-chromosome single-nucleotide polymorphisms (Y-SNPs), were analyzed on 14 human remains excavated from the Dadianzi site. The 14 sequences, which contained 13 haplotypes, were assigned to 9 haplogroups, and Y-SNP typing of 5 male individuals assigned them to haplogroups N (M231) and O3 (M122). The results indicate that the LXC population mainly included people carrying haplogroups from northern Asia who had lived in this region since the Neolithic period, as well as genetic evidence of immigration from the Central Plain. Later in the Bronze Age, part of the population migrated to the south away from a cooler climate, which ultimately influenced the gene pool in the Central Plain. Thus, climate change is an important factor, which drove the population migration during the Bronze Age in northern China. Based on these results, the local genetic continuity did not seem to be affected by outward migration, although more data are needed especially from other ancient populations to determine the influence of return migration on genetic continuity.

    Frank, Patrick; Caruso, Francesco; Caponetti, Eugenio

    2012-05-15

    In 2008 the rostrum from an ancient warship was recovered from the Mediterranean near Acqualadrone, Sicily. To establish its provenance and condition, samples of black and brown rostrum wood were examined using sulfur K-edge X-ray absorption spectroscopy (XAS) and gas chromatography/mass spectrometry (GC/MS). GC/MS of pyrolytic volatiles yielded only guaiacyl derivatives, indicating construction from pinewood. A derivatized extract of black wood yielded forms of abietic acid and sandaracopimaric acid consistent with pine pitch waterproofing. Numerical fits to the sulfur K-edge XAS spectra showed that about 65% of the endogenous sulfur consisted of thiols and disulfides. Elemental sulfur was about 2% and 7% in black and brown wood, respectively, while pyritic sulfur was about 12% and 6%. About 2% of the sulfur in both wood types was modeled as trimethylsulfonium, possibly reflecting biogenic (dimethylsulfonio)propionate. High-valent sulfur was exclusively represented by sulfate esters, consistent with bacterial sulfotransferase activity. Traces of chloride were detected, but no free sulfate ion. In summary, the rostrum was manufactured of pine wood and subsequently waterproofed with pine pitch. The subsequent 2300 years included battle, foundering, and marine burial followed by anoxia, bacterial colonization, sulfate reduction, and mobilization of transition metals, which produced pyrite and copious appended sulfur functionality.

    2015-01-01

    This article describes the history of the nosology of anxiety disorders. Greek and Latin physicians and philosophers distinguished anxiety from other types of negative affect, and identified it as a medical disorder. Ancient Epicurean and Stoic philosophers suggested techniques to reach an anxiety-free state of mind that are reminiscent of modern cognitive psychology. Between classical antiquity and the late 19th century there was a long interval during which anxiety was not classified as a s...

    Leprosy has afflicted humankind throughout history leaving evidence in both early texts and the archaeological record. In Britain, leprosy was widespread throughout the Middle Ages until its gradual and unexplained decline between the 14th and 16th centuries. The nature of this ancient endemic leprosy and its relationship to modern strains is only partly understood. Modern leprosy strains are currently divided into 5 phylogenetic groups, types 0 to 4, each with strong geographical links. Until recently, European strains, both ancient and modern, were thought to be exclusively type 3 strains. However, evidence for type 2 strains, a group normally associated with Central Asia and the Middle East, has recently been found in archaeological samples in Scandinavia and from two skeletons from the medieval leprosy hospital (or leprosarium) of St Mary Magdalen, near Winchester, England. Here we report the genotypic analysis and whole genome sequencing of two further ancient M. leprae genomes extracted from the remains of two individuals, Sk14 and Sk27, that were excavated from 10th-12th century burials at the leprosarium of St Mary Magdalen. DNA was extracted from the surfaces of bones showing osteological signs of leprosy. Known M. leprae polymorphisms were PCR amplified and Sanger sequenced, while draft genomes were generated by enriching for M. leprae DNA, and Illumina sequencing. SNP-typing and phylogenetic analysis of the draft genomes placed both of these ancient strains in the conserved type 2 group, with very few novel SNPs compared to other ancient or modern strains. The genomes of the two newly sequenced M. leprae strains group firmly with other type 2F strains. Moreover, the M. leprae strain most closely related to one of the strains, Sk14, in the worldwide phylogeny is a contemporaneous ancient St Magdalen skeleton, vividly illustrating the epidemic and clonal nature of leprosy at this site. The prevalence of these type 2 strains indicates that type 2F strains

    Characterizing genetic diversity in Africa is a crucial step for most analyses reconstructing the evolutionary history of anatomically modern humans. However, historic migrations from Eurasia into Africa have affected many contemporary populations, confounding inferences. Here, we present a 12.5×coverage ancient genome of an Ethiopian male ("Mota") who lived approximately 4500 years ago. We use this genome to demonstrate that the Eurasian backflow into Africa came from a population closely related to Early Neolithic farmers, who had colonized Europe 4000 years earlier. The extent of this backflow was much greater than previously reported, reaching all the way to Central, West, and Southern Africa, affecting even populations such as Yoruba and Mbuti, previously thought to be relatively unadmixed, who harbor 6 to 7% Eurasian ancestry.

  5. The Hidden History of a Famous Drug: Tracing the Medical and Public Acculturation of Peruvian Bark in Early Modern Western Europe (c. 1650-1720).

    Klein, Wouter; Pieters, Toine

    2016-10-01

    The history of the introduction of exotic therapeutic drugs in early modern Europe is usually rife with legend and obscurity and Peruvian bark is a case in point. The famous antimalarial drug entered the European medical market around 1640, yet it took decades before the bark was firmly established in pharmaceutical practice. This article argues that the history of Peruvian bark can only be understood as the interplay of its trajectories in science, commerce, and society. Modern research has mostly focused on the first of these, largely due to the abundance of medico-historical data. While appreciating these findings, this article proposes to integrate the medical trajectory in a richer narrative, by drawing particular attention to the acculturation of the bark in commerce and society. Although the evidence we have for these two trajectories is still sketchy and disproportionate, it can nevertheless help us to make sense of sources that have not yet been an obvious focus of research. Starting from an apparently isolated occurrence of the drug in a letter, this article focuses on Paris as the location where medical and public appreciation of the bark took shape, by exploring several contexts of knowledge circulation and medical practice there. These contexts provide a new window on the early circulation of knowledge of the bark, at a time when its eventual acceptance was by no means certain. © The Author 2016.

  6. Tracking the multi-stage exhumation history of the western Chinese Tianshan by Apatite Fission Track (AFT) dating - Implications for the preservation of epithermal deposits in ancient orogenic belt

    Science.gov (United States)

    Wang, Yannan; Cai, Keda

    2017-04-01

    The western Chinese Tianshan, located in the southern domain of the Central Asian Orogenic Belt (CAOB), was originally constructed by multiple accretion-collision processes in the Paleozoic, and was superimposed by complex intracontinental tectonic evolution in the Mesozoic-Cenozoic. Understanding the timing and mechanism of the latter geological processes is critical to unravel the preservation conditions of the epithermal deposits in the western Chinese Tianshan. This work presents new apatite fission track (AFT) data for three mountain ranges of the western Chinese Tianshan to track their exhumation history. Our AFT data gave a wide range of ages from 76.8 ± 5.5 Ma to 182.3 ± 9.9 Ma, and the mean confined fission track lengths are between 9.8 ± 0.5 μm and 12.3 ± 0.2 μm. The new data, in combination with the thermal history modeling,enable us to attribute the exhumation history to three primary stages, including Early Permian (300-280 Ma), Late Triassic-Early Cretaceous (230-130 Ma), and Late Oligocene-Early Miocene (30-20 Ma). The first stage may be caused by the terrane accretion-collision in the late Paleozoic. The second stage was likely related to the closure of the Mongol-Okhotsk Ocean during the Mesozoic. The last one is regarded as the result of the collision between the Indian Plate and the Eurasia Plate in the Cenozoic. The extraordinary exhumation processes of these three major mountain ranges might have been responsible for sediment supply to the corresponding intra-mountain basins in the western Chinese Tianshan, and the particularly mountain-basin coupling evolution is ascribed to an essential condition for the preservation of epithermal deposits in ancient orogenic belt.

    Despite significant advances made in the understanding of its epidemiology, foot and mouth disease virus (FMDV) is among the most unexpected agricultural devastating plagues. While the disease manifests itself as seven immunologically distinct strains their origin, population dynamics, migration patterns and divergence times remain unknown. Herein we have assembled a comprehensive data set of gene sequences representing the global diversity of the disease and inferred the time-scale and evolutionary history for FMDV. Serotype-specific rates of evolution and divergence times were estimated using a Bayesian coalescent framework. We report that an ancient precursor FMDV gave rise to two major diversification events spanning a relatively short interval of time. This radiation event is estimated to have taken place towards the end of the 17th and the beginning of the 18th century giving us the present circulating Euro-Asiatic and South African viral strains. Furthermore our results hint that Europe acted as a possible hub for the disease from where it successfully dispersed elsewhere via exploration and trading routes

    The 28 samples of glazes and bodies of ancient Chinese Ru porcelains are analyzed by neutron activation. The 36 element contents in each sample are determined. The neutron activation analysis (NAA) data are analyzed by fuzzy cluster. The trend cluster diagram is obtained. The result shows that the ancient Chinese Ru porcelains were most probably from the same raw material source though they were from different time, fired in different kilns and in different colors. The near provenance relation between ancient Jun porcelain and ancient Ru porcelain is preliminarily analyzed. The two modern Ru porcelains approximate to ancient Ru porcelains, one becomes estranged from ancient Ru porcelains. Jingdezhen porcelain is unconcerned with Ru porcelains

  9. Early-Modern Irreligion and Theological Analogy: A Response to Gavin Hyman’s A Short History of Atheism

    Directory of Open Access Journals (Sweden)

    Daniel J Linford

    2016-01-01

    Full Text Available Historically, many Christians have understood God’s transcendence to imply God’s properties categorically differ from any created properties. For multiple historical figures, a problem arose for religious language: how can one talk of God at all if none of our predicates apply to God? What are we to make of creeds and Biblical passages that seem to predicate creaturely properties, such as goodness and wisdom, of God? Thomas Aquinas offered a solution: God is to be spoken of only through analogy (the doctrine of analogy. Gavin Hyman argues Aquinas’s doctrine of analogy was neglected prior to the early-modern period and the neglect of analogy produced the conception of a god vulnerable to atheistic arguments. Contra Hyman, in this paper, I show early-modern atheism arose in a theological context in which there was an active debate concerning analogy. Peter Browne (1665–1735 and William King (1650–1729 offered two competing conceptions of analogical predication that were debated through the 19th century, with interlocutors such as the freethinker Anthony Collins (1676–1729, theologian/philosopher George Berkeley (1685–1753, and skeptic David Hume (1711–1776. Lastly, I discuss the 18th century debate over theological analogy as part of the background relevant to understanding Hume’s 'Dialogues Concerning Natural Religion'.

    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.

  11. 'GETTING' THE POX: Reflections by an Historian on How to Write the History of Early Modern Disease.

    Science.gov (United States)

    Stein, Claudia

    This article reflects upon the recent return to linear history writing in medical history. It takes as its starting point a critique of the current return to constructivist ideas, suggesting the use of other methodological choices and interpretations to the surviving archival and textural sources of the sixteenth century pox. My investigation analyses the diagnostic act as an effort to bring together a study of medical semiotics. Medical semiotics considers how signs speak through the physical body, coached within a particular epistemology. There are no hidden meanings behind the visible sign or symptom - it is tranparent to the calculative and authoritative gaze and language of the doctor. It concerns how diseases came into being, the relationships they have constituted, the power they have secured and the actual knowledge/power they have eclipsed or are eclipsing. From such a perspective, "getting the pox" is not a bad thing. A methodological turn to medical semiotics reminds us that the history of disease should be an inquiry both into the grounds of our current knowledge and beliefs about disease and how they inspire our writing, as well as the analytical categories that establish their inevitability.

    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.

    U-Pb analyses were carried out on detrital zircon grains from major river-mouth sediments draining South Korea to infer provenance characteristics and the crustal growth history of the southern Korean Peninsula, using a laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS). The Korean Peninsula is located in the East Asian continental margin and mainly comprises three Precambrian massifs and two metamorphic belts in between them. We obtained 515 concordant to slightly discordant zircon ages ranging from ca. 3566 to ca. 48 Ma. Regardless of river-mouth location, predominance of Mesozoic (249e79 Ma) and Paleoproterozoic (2491e1691 Ma) ages with subordinate Archean ages in-dicates that the zircon ages reflect present exposures of plutonic/metamorphic rocks in the drainage basins of the South Korean rivers and the crustal growth of the southern Korean Peninsula was focused in these two periods. Comparison of detrital zircon-age data between the North and South Korean river sediments reveals that the Paleoproterozoic zircon age distributions of both regions are nearly identical, while the NeoproterozoicePaleozoic ages exist and the Mesozoic ages are dominant in southern Korean Peninsula. This result suggests that Precambrian terrains in Korea record the similar pre-Mesozoic magmatic history and that the influence of Mesozoic magmatism was mainly focused in South Korea.

    1997-01-01

    In the 16th, 17th and 18th century "Glossopetrae", popularly known as "Lingue di Serpi", found on the Mediterranean island of Malta, were extensively used for medical purposes as antidotes. These fossil teeth, including specimens of the "Carcharodon Megalodon" (an extinct variant of the great white shark), were ground to powder or used as amulet pendants and "credence" and exported to pharmacies and shops in various cities of Europe. In antiquity, authors like Plinius or Solinus, excluding any religious connotations, had regarded "Glossopetrae" as objects "fallen from heaven on dark moonless nights". However, from the beginning of the 16th century the miraculous antidotic power of the specimens found at Malta was very strongly connected with the Pauline cult there. This cult owed ist origin to the excerpt of the shipwreck of the Apostle of the Gentiles on this island, as recorded in the New Testament. As in so many cases found in medieval and early modern medicine and pharmacy, the renown, collection, distribution and use of the antidote "Glossopetrae" or "Lingue di Serpi" was never limited to its real chemical and pharmaceutical properties. In the period of enlightenment and secular thinking mythic medicine as "Glossopetrae" had lost ist "magical" power. Consequently, with beginning of the late 18th century also the Maltese "Glossopetrae" featured in literature merely as exotic objects of curiosity or symbols of an age bound to medical superstition.

The authors also focus on the relevance of the chosen theme because of the formation of new industrial policy institutions. The hypothesis of the study is based on identifying a set of basis factors of building effective institutions: system, decentralization mechanism, clustering, given a set of groups of interests of subjects of industrial policy implementation. Institutions of new industrial policy implementation in contemporary Russia are focused on achieving multifaceted tasks on a temporary basis, the level of implementation, the degree of relevance, therefore, the conclusion regarding the effective implementation of the strategy of economic development of modern Russia, which should include the following institutions: government programs, effective transparent public procurement, institutional design through the creation of specialized, diversified institutions of industrial-innovative development. Named structural elements must be systematically subordinated to the interests of macro-, meso- and micro levels of economic system. Special importance must have experience of building the institutional system of the new industrial policy, which gives effective results on the social-economic development.

  20. Radiocarbon dating of ancient Japanese documents

    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.

    2017-11-01

    Two datasets, the geologic record and the genetic content of extant organisms, provide complementary insights into the history of how key molecular components have shaped or driven global environmental and macroevolutionary trends. Changes in global physico-chemical modes over time are thought to be a consistent feature of this relationship between Earth and life, as life is thought to have been optimizing protein functions for the entirety of its approximately 3.8 billion years of history on the Earth. Organismal survival depends on how well critical genetic and metabolic components can adapt to their environments, reflecting an ability to optimize efficiently to changing conditions. The geologic record provides an array of biologically independent indicators of macroscale atmospheric and oceanic composition, but provides little in the way of the exact behaviour of the molecular components that influenced the compositions of these reservoirs. By reconstructing sequences of proteins that might have been present in ancient organisms, we can downselect to a subset of possible sequences that may have been optimized to these ancient environmental conditions. How can one use modern life to reconstruct ancestral behaviours? Configurations of ancient sequences can be inferred from the diversity of extant sequences, and then resurrected in the laboratory to ascertain their biochemical attributes. One way to augment sequence-based, single-gene methods to obtain a richer and more reliable picture of the deep past, is to resurrect inferred ancestral protein sequences in living organisms, where their phenotypes can be exposed in a complex molecular-systems context, and then to link consequences of those phenotypes to biosignatures that were preserved in the independent historical repository of the geological record. As a first step beyond single-molecule reconstruction to the study of functional molecular systems, we present here the ancestral sequence reconstruction of the

    Full Text Available Science assumes its contemporary identity as a result of the stages of magic, religion and reason. The religious stage starts with the invention of writing and this stage leaves its place to reason with Thales in Ancient Greece. Knowledge eludes from religious beliefs. Ways to reach accurate, reliable and realistic knowledge are sought, along with the answer for what knowledge is. Therefore, beginning of the science is taken into consideration together with science and philosophy. The purpose of this study is to approach knowledge and science of the ancient age in Mesopotamia, Egypt and Ancient Greece in general terms and to determine the relationship between the knowledge produced in those places and libraries established. The hypothesis has been determined as “Egypt and Mesopotamia at the starting point of the history of science and science, and libraries in Ancient Greece have developed parallelly to each other.” The scope of the study has been limited to Mesopotamia, Egypt and Ancient Greece; and Ancient Greece has been explained, with descriptive method, in the frame of the topics of Ionia, Athens, Hellenistic Period and Rome. Many archives and libraries have been established in the ancient age. The difference between an archive and a library has been mentioned first, and then, various libraries have been introduced such as Nineveh in Mesopotamia, Alexandria in Ancient Greece and many others in Egypt. It has been clearly distinguished that there had been a very tight relationship between knowledge production and library, especially with the Library of Alexandria.

    Second-harmonic generation imaging (SHG) captures triple helical collagen molecules near tissue surfaces. Biomedical research routinely utilizes various imaging software packages to quantify SHG signals for collagen content and distribution estimates in modern tissue samples including bone. For the first time using SHG, samples of modern, medieval, and ice age bones were imaged to test the applicability of SHG to ancient bone from a variety of ages, settings, and taxa. Four independent techniques including Raman spectroscopy, FTIR spectroscopy, radiocarbon dating protocols, and mass spectrometry-based protein sequencing, confirm the presence of protein, consistent with the hypothesis that SHG imaging detects ancient bone collagen. These results suggest that future studies have the potential to use SHG imaging to provide new insights into the composition of ancient bone, to characterize ancient bone disorders, to investigate collagen preservation within and between various taxa, and to monitor collagen decay regimes in different depositional environments.

    Full Text Available The author of the article set the goal to analyse the published academic/ scientific, popular scientific publications and the published results of Ukrainian museums’ practical developments for 1990-2010s, which in total can be described as a museum andragogics or informal adult education by museum means. Initially, it was found that despite the growing interest in these kinds of museum activities, the available research body is not systematized. It was found that brief reviews of the problem’s historiography are present mostly in preambles of museology, pedagogy, museums history articles. They are often related to the topic indirectly. Attempts to study purposefully the subject are now rare, although their aim is to summarize the existing Ukrainian experience. It was determined that, although it is impossible now to determine the museum andragogics as a separate sphere of knowledge on the basis of a small number of published investigations of Ukrainian specialists. These investigations are reflecting the national museums and available foreign publications’ experience in this sphere (translated into Ukrainian or published in Russian. But the formation of the andragogics in Ukraine is actual and necessary on the way towards the integration into the global cultural space. Summarizing the material the conclusion was made that the museum andragogics and non-formal adult education in museums are promising areas of scientific knowledge. A contribution of the museum’s and other Ukrainian connected sectors professionals in the process by years 2012-13 is notable both at the level of the foreign experience’s study and the reflection in practice, research, scientific and popular publications. However, until now there was no such activity surge, as it happened in the spheres of museum marketing or sociology. Such forms of activity as «Workshop», «Summer school», public lecture are not known and used enough by domestic museums, and therefore by

    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.'

    Altogether 28 samples, mainly including glazes and bodies of ancient Chinese Ru porcelain, were analyzed by NAA technique and the contents of 36 elements were compared. The scatter analysis for nine fingerprint-elements indicates that almost all ancient Chinese Ru porcelain samples had nearly identical and long-term stable source of raw materials although they were fired in different kilns, at varying time and with distinct colors, and moreover, the source of raw materials for modern Ru porcelain seems to approach that for ancient one. The close provenance relation between ancient Jun porcelain and ancient Ru porcelain is also preliminarily verified. The glaze material of Jingdezhen white porcelain is totally different from all other samples. It shows that the former came from a separate source

    This article attempts to analyze the crucial link between the plant Agnus castus and human health, particularly hormonal status, with special reference to the needs of the society of ancient Sparta. The ancient Spartans used Agnus both as a cure for infertility and as a remedy to treat battle wounds. These special properties were recognized by the sanctuary of Asclepios Agnita, which was located in Sparta, as well as by medical practitioners in Sparta during the classical, Hellenistic and Roman ages.

    Full Text Available Main objective of the essay under consideration was investigation and characterized most important source materials stocked at the Archive of the Cracow’s Dominican Province to present the history of their studium generale during the Modern period. Also, the current knowledge of a.m. period of studium generale was screened- out and some searching hypothesis were proposed concerning the history of the Cracow’s Dominican studium generale. The searching time frame have been limited to XVI up to XVII century. Taken into consideration, the current status of research works performed so far, one ought to stated that the Modern Epoch has not been searched out with the same consciousness compare to the Medieval one. As the most important printed source materials, one ought to account the documents issued by the general and provincial chapters of the Convent. The documents of the provincial chapters have been listed and screened by Father Fabian Madura, and were stocked as the typescript formats at the Cracow’s Dominican Convent Library. Based on the searched source materials of General Chapter of Dominican Convent at Cracow, it is possible to present the general overview of the convent education system and its changes in due time. Due to the records found it would be possible to identify – position and name – the Dominicans nominated to the Convent stadium generale. The most important manuscript stocked at the Cracow’s Dominican Convent Archive as the education system is concern, is so called Liber Studii Generalis cracoviensis (rkps 20. This manuscript covers the list of friars who have been nominated to work at stadium generale. A.m. document has to verify and compare with other sources.

    Esther J Lee

    Full Text Available Modern Arctic Siberia provides a wealth of resources for archaeological, geological, and paleontological research to investigate the population dynamics of faunal communities from the Pleistocene, particularly as the faunal material coming from permafrost has proven suitable for genetic studies. In order to examine the history of the Canid species in the Siberian Arctic, we carried out genetic analysis of fourteen canid remains from various sites, including the well-documented Upper Paleolithic Yana RHS and Early Holocene Zhokhov Island sites. Estimated age of samples range from as recent as 1,700 years before present (YBP to at least 360,000 YBP for the remains of the extinct wolf, Canis cf. variabilis. In order to examine the genetic affinities of ancient Siberian canids species to the domestic dog and modern wolves, we obtained mitochondrial DNA control region sequences and compared them to published ancient and modern canid sequences. The older canid specimens illustrate affinities with pre-domestic dog/wolf lineages while others appear in the major phylogenetic clades of domestic dogs. Our results suggest a European origin of domestic dog may not be conclusive and illustrates an emerging complexity of genetic contribution of regional wolf breeds to the modern Canis gene pool.

     Although the exact time of performing plastic surgery is not addressed in the medical and historical literature, it can be supposed that these surgical procedures have a long and fascinating history.  Recent excavations provided many documents regarding the application of medical instruments, surgical and even reconstructive procedures during the pre-historic and ancient periods. Actually, there is no historical definite time-zone separating general and cosmetic operations in the pre-modern time; however, historically there have been many surgeons who tried to perform reconstructive procedures during their usual medical practice. This article presents a brief look at the history of plastic surgery form the ancient to the contemporary era, with a special focus on Iran.

    During its evolution the cesarean section has meant different things to different people. The indications for it have changed throughout the course of history. From the initial purpose to retrieve an infant from a dead or dying mother in order to bury the child separately from his mother, to contemporary indications. This article strives to follow the roots of this common procedure--starting from the descriptions in the ancient Greek mythology, through the imperial Roman law, aspects of Judaism and the evolution of the procedure throughout modern history. Major improvements in the surgical techniques, the introduction of anesthesia and aseptic procedures contributed to the decline in mortality and morbidity rates. We will attempt to find the etymology for the expression "cesarean section" which has commonly been accounted to Julius Caesar's name, although history denies it. This review takes us on a historical journey, from ancient times to nowadays, in which we follow the course and nature of a procedure being performed daily in thousands of hospitals.

    Weinberg, Steven

    2015-01-01

    A masterful commentary on the history of science from the Greeks to modern times, by Nobel Prize-winning physicist Steven Weinberg—a thought-provoking and important book by one of the most distinguished scientists and intellectuals of our time. In this rich, irreverent, and compelling history, Nobel Prize-winning physicist Steven Weinberg takes us across centuries from ancient Miletus to medieval Baghdad and Oxford, from Plato’s Academy and the Museum of Alexandria to the cathedral school of Chartres and the Royal Society of London. He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world—they did not understand what there is to understand, or how to understand it. Yet over the centuries, through the struggle to solve such mysteries as the curious backward movement of the planets and the rise and fall of the tides, the modern discipline of science eventually emerged. Along the way, Weinberg examines historic clashes and collaborations betw...

  20. Interdisciplinary investigation on ancient Ephedra twigs from Gumugou Cemetery (3800 B.P.) in Xinjiang region, northwest China.

    In the dry northern temperate regions of the northern hemisphere, the genus Ephedra comprises a series of native shrub species with a cumulative application history reaching back well over 2,000 years for the treatment of asthma, cold, fever, as well as many respiratory system diseases, especially in China. There are ethnological and philological evidences of Ephedra worship and utilization in many Eurasia Steppe cultures. However, no scientifically verifiable, ancient physical proof has yet been provided for any species in this genus. This study reports the palaeobotanical finding of Ephedra twigs discovered from burials of the Gumugou archaeological site, and ancient community graveyard, dated around 3800 BP, in Lop Nor region of northwestern China. The macro-remains were first examined by scanning electron microscope (SEM) and then by gas chromatography-mass spectrometry (GC-MS) for traits of residual biomarkers under the reference of modern Ephedra samples. The GC-MS result of chemical analysis presents the existence of Ephedra-featured compounds, several of which, including benzaldehyde, tetramethyl-pyrazine, and phenmetrazine, are found in the chromatograph of both the ancient and modern sample. These results confirm that the discovered plant remains are Ephedra twigs. Although there is no direct archaeological evidence for the indication of medicinal use of this Ephedra, the unified burial deposit in which the Ephedra was discovered is a strong indication of the religious and medicinal awareness of the human inhabitants of Gumugou towards this plant.

    Phylogenetic analyses including four allopatric species of Gyrodactylus von Nordmann, 1832 on the Eurasian minnow Phoxinus phoxinus (L.) (Cyprinidae) revealed incongruence between the nuclear ITS1-5.8S-ITS2 and mitochondrial cox1 phylogenies due to ancient hybridisation. Gyrodactylus pannonicus Molnár, 1968 was sampled close to its type-locality, the upper reaches of River Tisza, tributary of Danube in the Black Sea Basin. Faunistic search detected three new related species with maximum composite likelihood distances in cox1 between 16.8-23.2% (tentatively 1.3 to 1.8 My of divergence). Gyrodactylus albolacustris n. sp. recorded in the White Sea Basin, eastern Baltic Basin and Mongolia was close to G. pannonicus in the nuclear ITS (divergence of 0.9%), but diverged in cox1 by 19.8%. The Mongolian isolate of G. albolacustris n. sp. diverged from the European isolates in cox1 by 8.9%, suggesting 0.7 My of isolation. The two other new species differed from G. pannonicus by >4% in ITS and some large indels in ITS1, and by >20% in cox1. Gyrodactylus danastriae n. sp. was found in River Strwiąż, a tributary of the River Dniester (Black Sea Basin) and was characterised by smaller size of anchors and by 29-41 bp dimorphic insertion in ITS1. Gyrodactylus botnicus n. sp. is considered endemic in the Baltic Basin, but was also found in the White Sea Basin as a postglacial immigrant, where it had hybridised with G. albolacustris n. sp. in spite of the high divergence in ITS (3.9%) and cox1 (22%). The discordant nuclear and mitochondrial phylogenies revealed an ancient mitochondrial introgression: G. albolacustris n. sp. was derived from a hybridisation combining proto-pannonicus ITS with proto-danastriae mitochondria, perhaps 1.3 My ago. The postglacial hybridisation of G. albolacustris n. sp. (as the donor of mtDNA alb and ITS alb ) and G. botnicus n. sp. (donor of the ITS bot ) offered a model of shuffling of the genomic components: the process of the homogenisation

    Cities are increasingly the fundamental socio-economic units of human societies worldwide, but we still lack a unified characterization of urbanization that captures the social processes realized by cities across time and space. This is especially important for understanding the role of cities in the history of human civilization and for determining whether studies of ancient cities are relevant for contemporary science and policy. As a step in this direction, we develop a theory of settlement scaling in archaeology, deriving the relationship between population and settled area from a consideration of the interplay between social and infrastructural networks. We then test these models on settlement data from the Pre-Hispanic Basin of Mexico to show that this ancient settlement system displays spatial scaling properties analogous to those observed in modern cities. Our data derive from over 1,500 settlements occupied over two millennia and spanning four major cultural periods characterized by different levels of agricultural productivity, political centralization and market development. We show that, in agreement with theory, total settlement area increases with population size, on average, according to a scale invariant relation with an exponent in the range [Formula: see text]. As a consequence, we are able to infer aggregate socio-economic properties of ancient societies from archaeological measures of settlement organization. Our findings, from an urban settlement system that evolved independently from its old-world counterparts, suggest that principles of settlement organization are very general and may apply to the entire range of human history.

    2008-05-01

    Bladder stone was a common ailment plaguing mankind from antiquity to the 20th century. Largely forgotten today, lithotomy relieved the anguish of bladder stones and identified urology as a medical specialty nearly 2500 years ago. The historical literature pertaining to lithotomy was reviewed. Translated and original documents describing operative techniques and developments pertaining to the history of lithotomy were obtained through the internet and library sources. The ancient art of lithotomy was first recorded by the Greeks and evolved through five phases: the Celsian method, or 'lesser operation'; the Marian, or 'greater operation'; the lateral operation; suprapubic cystotomy, or 'high operation', and proctocystotomy. The practice of open lithotomy ceased to exist owing to better minimally invasive alternative methods and most notably by the virtual disappearance of bladder stones in modern man. The history of lithotomy is a fascinating story of how early surgeons forced by the culture and customs of the time dealt with common but devastating bladder stones. Out of their efforts, urology was born.

    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. Dwarfs in ancient Egypt.

    Ancient Egypt was one of the most advanced and productive civilizations in antiquity, spanning 3000 years before the "Christian" era. Ancient Egyptians built colossal temples and magnificent tombs to honor their gods and religious leaders. Their hieroglyphic language, system of organization, and recording of events give contemporary researchers insights into their daily activities. Based on the record left by their art, the ancient Egyptians documented the presence of dwarfs in almost every facet of life. Due to the hot dry climate and natural and artificial mummification, Egypt is a major source of information on achondroplasia in the old world. The remains of dwarfs are abundant and include complete and partial skeletons. Dwarfs were employed as personal attendants, animal tenders, jewelers, and entertainers. Several high-ranking dwarfs especially from the Old Kingdom (2700-2190 BCE) achieved important status and had lavish burial places close to the pyramids. Their costly tombs in the royal cemeteries and the inscriptions on their statutes indicate their high-ranking position in Egyptian society and their close relation to the king. Some of them were Seneb, Pereniankh, Khnumhotpe, and Djeder. There were at least two dwarf gods, Ptah and Bes. The god Ptah was associated with regeneration and rejuvenation. The god Bes was a protector of sexuality, childbirth, women, and children. He was a favored deity particularly during the Greco-Roman period. His temple was recently excavated in the Baharia oasis in the middle of Egypt. The burial sites and artistic sources provide glimpses of the positions of dwarfs in daily life in ancient Egypt. Dwarfs were accepted in ancient Egypt; their recorded daily activities suggest assimilation into daily life, and their disorder was not shown as a physical handicap. Wisdom writings and moral teachings in ancient Egypt commanded respect for dwarfs and other individuals with disabilities. Copyright (c) 2005 Wiley-Liss, Inc.

    Forty-three samples of ancient Jun porcelains and so on were chosen. Neutron activation analysis (NAA) was used to measure the 36 trace elements in every sample. Seven elements were chosen as the 'fingerprint elements'. The provenance of the glazes and bodies of ancient Chinese Jun porcelain were investigated by the fingerprint element analysis method. The result shows that although the ancient Chinese Jun porcelain samples have been leapt over six hundred years, and glaze colors are utterly different and are from many different kilns, there are long term, stable and same mainly raw material source. The near provenance relation between ancient Jun porcelain and ancient Ru porcelain is preliminarily analyzed. A few modern Jun porcelains approximate from ancient Jun porcelains, the majority become estranged from ancient Jun porcelain

    The population history of the Iberian wild goat and the Alpine ibex has been closely related to that of humans since the Palaeolithic. Current molecular and paleontological studies differ substantially on the phylogenetic origin of the European wild goats, possibly due the loss of genetic variation through time. We investigated the phylogenetic relationship between the Alpine ibex (Capra ibex) and the Iberian wild goat (Capra pyrenaica) including different Iberian wild goat subspecies by applying ancient DNA techniques combined with Next Generation Sequencing technologies. We analysed the cytochrome b gene of the mitochondrial genome in 33 ancient and modern European wild goats from Spain and France together with publicly available genetic information of modern wild goats. This work uncovers for the first time ancient genetic information of the Iberian wild goat and the Alpine ibex, spanning a time range of approximately 40,000 years to the present. Our results suggest genetic continuity between ancient and modern populations and indicate a monophyletic origin of the Alpine ibex and the Iberian wild goat when compared to other Capra species. The monophyly of both species is in agreement with other molecular studies based only on modern populations, therefore supporting one-wave migration of wild goats into Western Europe followed by possible allopatric speciation. We observe three major clades of wild goats in Western Europe: Capra ibex, Capra pyrenaica pyrenaica and the group containing the subspecies Capra pyrenaica hispanica and Capra pyrenaica victoriae. This genetic structure recognizes the distinctiveness of the bucardo (C. p. pyrenaica) from the rest of Iberian wild goats and thus supports the idea that this group is an Evolutionary Significant Unit. The divergence time estimated here indicates an almost contemporaneous split between the three clades around 50,000-90,000 years BP.

  16. Trepanation in Ancient China.

    Trepanation, the process of making a burr hole in the skull to access the brain, is an ancient form of a primitive craniotomy. There is widespread evidence of contributions made to this practice by ancient civilizations in Europe, Africa, and South America, where archaeologists have unearthed thousands of trepanned skulls dating back to the Neolithic period. Little is known about trepanation in China, and it is commonly believed that the Chinese used only traditional Chinese medicine and nonsurgical methods for treating brain injuries. However, a thorough analysis of the available archeological and literary evidence reveals that trepanation was widely practiced throughout China thousands of years ago. A significant number of trepanned Chinese skulls have been unearthed showing signs of healing and suggesting that patients survived after surgery. Trepanation was likely performed for therapeutic and spiritual reasons. Medical and historical works from Chinese literature contain descriptions of primitive neurosurgical procedures, including stories of surgeons, such as the legendary Hua Tuo, and surgical techniques used for the treatment of brain pathologies. The lack of translation of Chinese reports into the English language and the lack of publications on this topic in the English language may have contributed to the misconception that ancient China was devoid of trepanation. This article summarizes the available evidence attesting to the performance of successful primitive cranial surgery in ancient China. Copyright © 2016 Elsevier Inc. All rights reserved.

    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

    The intentional and unintentional movement of plants and animals by humans has transformed ecosystems and landscapes globally. Assessing when and how a species was introduced are central to managing these transformed landscapes, particularly in island environments. In the Gulf of Alaska, there is considerable interest in the history of mammal introductions and rehabilitating Gulf of Alaska island environments by eradicating mammals classified as invasive species. The Arctic ground squirrel (Urocitellus parryii) is of concern because it affects vegetation and seabirds on Gulf of Alaska islands. This animal is assumed to have been introduced by historic settlers; however, ground squirrel remains in the prehistoric archaeological record of Chirikof Island, Alaska, challenge this timeline and suggest they colonized the islands long ago. We used 3 lines of evidence to address this problem: direct radiocarbon dating of archaeological squirrel remains; evidence of prehistoric human use of squirrels; and ancient DNA analysis of dated squirrel remains. Chirikof squirrels dated to at least 2000 years ago, and cut marks on squirrel bones suggested prehistoric use by people. Ancient squirrels also shared a mitochondrial haplotype with modern Chirikof squirrels. These results suggest that squirrels have been on Chirikof longer than previously assumed and that the current population of squirrels is closely related to the ancient population. Thus, it appears ground squirrels are not a recent, human-mediated introduction and may have colonized the island via a natural dispersal event or an ancient human translocation. © 2016 The Authors.

  2. Ancient Terrestrial Carbon: Lost and Found

    Freeman, K. H.

    2017-12-01

    Carbon fluxes in terrestrial environments dominate the global carbon cycle. The fluxes of terrestrial carbon are strongly tied to regional climate due to the influences of temperature, water, and nutrient dynamics on plant productivity. However, climate also influences the destruction of terrestrial organic matter, through weathering, erosion, and biomass loss via fire and oxidative microbial processes. Organic geochemical methods enable us to interrogate past terrestrial carbon dynamics and learn how continental processes might accelerate, or mitigate carbon transfer to the atmosphere, and the associated greenhouse warming. Terrestrial soil systems represent the weathering rind of the continents, and are inherently non-depositional and erosive. The production, transport, and depositional processes affecting organics in continental settings each impart their own biases on the amount and characteristics of preserved carbon. Typically, the best archives for biomarker records are sediments in ancient lakes or subaqueous fans, which represents a preservation bias that tends to favor wetter environments. Paleosols, or ancient soils, formed under depositional conditions that, for one reason or another, truncated soil ablation, erosion, or other loss processes. In modern soils, widely ranging organic carbon abundances are almost always substantially greater than the trace amounts of carbon left behind in ancient soils. Even so, measureable amounts of organic biomarkers persist in paleosols. We have been investigating processes that preserve soil organic carbon on geologic timescales, and how these mechanisms may be sensitive to past climate change. Climate-linked changes in temperature, moisture, pH, and weathering processes can impact carbon preservation via organo-mineral sorption, soil biogeochemistry, and stability based on the physical and chemical properties of organic compounds. These will be discussed and illustrated with examples from our studies of Cenozoic

  4. Contesting Conceptual Boundaries: Byzantine Literature and Its History

    2015-07-01

    Full Text Available The paper presents the problems of writing a history of Byzantine literature in the context of postmodern anxieties about canonization, authority and narrative histories of literature. An essential difficulty for such a project is the fact that Byzantine literature has been viewed as a continuation of or appendix to Ancient Greek literature, while, on the other, it has been divided into 'learned' and 'vernacular', the latter category having been defined as Modern Greek since the middle of the nineteenth century. The paper offers two sets of criteria for establishing new concepts of periodization and taxonomy. A series of examples are indicatively adduced in order to explain the scientific and ideological impasse in which Byzantine Studies have found themselves at the end of the previous century, while delineating a proposal for a different approach to content and structure of a wider synthesis. Writing a ‘new’ history of Byzantine literature is an experiment in proposing a radical paradigm shift by means of which this particular literary production in Medieval Greek can be studied within the broader context of Medieval European literatures as an integrated entity rather than as a separate and peripheral phase in the histories of Ancient or Modern Greek literature.

    2013-01-01

    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.

    Full Text Available A strategy for the second modernization raises, beyond objectives, a series of epistemicresponsibilities. It is known that modernization stemming from the Enlightment had, among other things,the pretense that it is a project which is self-legitimating. Its profound rationales are the only justification.Referential self-centering proved to be the one that made possible a practice of the new. Modernizationhaving the function of renouncing myth – meaning an eliminatory formula for the past – and thefixation in the opportunity and potentiality of the present, seemed to close an insoluble but extremelyengrossing problem: that of a propensity towards utopia, of the risky escape towards the future. Thetraditionalization of the new constitutes a support for the daring to break out of the captivity of themoment.Modernization becomes the experience of combining the new which, thus, creates a succession ofpresent times. The future is no longer the result of fantasy, but a system’s direct expression to combine thenew. Therefore the future is an option for one or another model of the present, often tested previouslysomewhere else. In a non-metaphysical way, the future can be seen, touched, tried, lived by simplegeographical movement. The sense of evolution has de-temporalized taking the form of the concomitant,parallel, enclosed, neighboring space. We just have to be in the trend, to evolve in the context.Globalization defines the context and its conception – as a project of the second modernity – showsus the trends. The problem is how to understand the context in order to find the sense of the trend. Are wethe load the sense with the values of the first modernity or will we have to turn to the values of anothermodernity? Why do we have to move away from the significance of the processes which made up the firstmodernity?

  8. Ancient Egyptian Medicine: A Systematic Review

    Directory of Open Access Journals (Sweden)

    Samuel Adu-Gyamfi

    2015-12-01

    Full Text Available Our present day knowledge in the area of medicine in Ancient Egypt has been severally sourced from medical papyri several of which have been deduced and analyzed by different scholars. For educational purposes it is always imperative to consult different literature or sources in the teaching of ancient Egypt and medicine in particular. To avoid subjectivity the author has found the need to re-engage the efforts made by several scholars in adducing evidences from medical papyri. In the quest to re-engage the efforts of earlier writers and commentaries on the medical papyri, we are afforded the opportunity to be informed about the need to ask further questions to enable us to construct or reconstruct both past and modern views on ancient Egyptian medical knowledge. It is this vocation the author sought to pursue in the interim, through a preliminary review, to highlight, comment and reinvigorate in the reader or researcher the need for a continuous engagement of some pertinent documentary sources on Ancient Egyptian medical knowledge for educational and research purposes. The study is based on qualitative review of published literature. The selection of those articles as sources was based on the focus of the review, in order to purposively select and comment on articles that were published based either on information from a medical papyrus or focused on medical specialization among the ancient Egyptians as well as ancient Egyptian knowledge on diseases and medicine. It was found that the Egyptians developed relatively sophisticated medical practices covering significant medical fields such as herbal medicine, gynecology and obstetrics, anatomy and physiology, mummification and even the preliminary form of surgery. These practices, perhaps, were developed as remedies for the prevailing diseases and the accidents that might have occurred during the construction of their giant pyramids. It must be stated that they were not without flaws. Also, the

  11. Linen in Ancient Egypt

    2014-01-01

    Full Text Available Egypt was famous through the Ancient Near East for both weaving linen cloth and the produced quantities. Cloth was sent as expensive gifts from one king to another and given to a laborer as wages in return for his work. Cloth was regarded as an essential element in everyday life as it could be used for everything: clothing, bedding, trappings for animals, or sails of a ship. It was in fact one of the most widely used item throughout Ancient Egypt. Although other textile fibers were used in Pharaonic Egypt, namely, sheep's wool, goat hair and a form of coir, the majority of textiles were made from the plant Linum usitatissimum, flax. Cloth made from this fiber is defined as linen. The research starts with a brief definition of the flax, and then reviews the scenes representing the sowing and the harvesting of its seeds. It also focuses on the way of removing the seeds heads, the preparing of the flax for spinning: retting, beating and scutching. After that, it deals with transforming flax into orderly lengths, and rolling it into balls or coils. The researcher as well studies the Ancient Egyptian spinning techniques: grasped spindle, support spindle and drop spinning; the different types of weaving: tabby weaves, basket weaves, tapestry weaves and warps-patterned weave and the types of looms that were in use in Egypt, namely, the horizontal and vertical looms.

  12. Taming the unknown a history of algebra from antiquity to the early twentieth century

    Katz, Victor J

    2014-01-01

    What is algebra? For some, it is an abstract language of x's and y's. For mathematics majors and professional mathematicians, it is a world of axiomatically defined constructs like groups, rings, and fields. Taming the Unknown considers how these two seemingly different types of algebra evolved and how they relate. Victor Katz and Karen Parshall explore the history of algebra, from its roots in the ancient civilizations of Egypt, Mesopotamia, Greece, China, and India, through its development in the medieval Islamic world and medieval and early modern Europe, to its modern form in the early twentieth century. Defining algebra originally as a collection of techniques for determining unknowns, the authors trace the development of these techniques from geometric beginnings in ancient Egypt and Mesopotamia and classical Greece. They show how similar problems were tackled in Alexandrian Greece, in China, and in India, then look at how medieval Islamic scholars shifted to an algorithmic stage, which was further dev...

    2015-01-19

    The field of palaeomicrobiology is dramatically expanding thanks to recent advances in high-throughput biomolecular sequencing, which allows unprecedented access to the evolutionary history and ecology of human-associated and environmental microbes. Recently, human dental calculus has been shown to be an abundant, nearly ubiquitous, and long-term reservoir of the ancient oral microbiome, preserving not only microbial and host biomolecules but also dietary and environmental debris. Modern investigations of native human microbiota have demonstrated that the human microbiome plays a central role in health and chronic disease, raising questions about changes in microbial ecology, diversity and function through time. This paper explores the current state of ancient oral microbiome research and discusses successful applications, methodological challenges and future possibilities in elucidating the intimate evolutionary relationship between humans and their microbes.

  15. 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

    There has been a dramatic surge in the interest of utilizing cannabis for epilepsy treatment in the US. Yet, access to cannabis for research and therapy is mired in conflicting regulatory policies and shifting public opinion. Understanding the current state of affairs in the medical cannabis debate requires an examination of the history of medical cannabis use. From ancient Chinese pharmacopeias to the current Phase III trials of pharmaceutical grade cannabidiol, this review covers the time span of cannabis use for epilepsy therapy so as to better assess the issues surrounding the modern medical opinion of cannabis use.

    50 samples of glazes and bodies of the ancient Chinese Ru porcelain, Jun porcelain and imitative ancient ceramics were analyzed by neutron activation analysis (NAA). The contents of 36 elements in each sample were measured. The NAA data were statistically treated by fuzzy cluster method and the trend cluster diagram was obtained. Their classes and raw material sources were determined. The results show that although these samples spanned hundreds of years, came from different kilns and had different glazes colors, the bodies of the ancient Chinese Ru porcelain and Jun porcelain belong to the same kind, the glazes of the ancient Chinese Ru porcelain is similar to the glazes of the ancient Chinese Jun porcelain. The originating places of the body raw material were concentrated, and that of the glaze raw materials were scattered, the source of the glaze raw material covered that the body raw material. The ancient Chinese Ru porcelain and Jun porcelain have basically the same raw material sources and the sources of raw material are stable in long time. It is found that most modern Jun porcelain samples are similar to the ancient Chinese Jun porcelain. Two modern Ru porcelain samples are similar to the ancient Chinese Ru porcelain, but another one drifts apart from the ancient Chinese Ru porcelain. Jingdezhen porcelain has no relation to Ru porcelain and Jun porcelain

    Ancient septicemic plague epidemics were reported to have killed millions of people for 2 millenniums. However, confident diagnosis of ancient septicemia solely on the basis of historical clinical observations is not possible. The lack of suitable infected material has prevented direct demonstration of ancient septicemia; thus, the history of most infections such as plague remains hypothetical. The durability of dental pulp, together with its natural sterility, makes it a suitable material on which to base such research. We hypothesized that it would be a lasting refuge for Yersinia pestis, the plague agent. DNA extracts were made from the dental pulp of 12 unerupted teeth extracted from skeletons excavated from 16th and 18th century French graves of persons thought to have died of plague ("plague teeth") and from 7 ancient negative control teeth. PCRs incorporating ancient DNA extracts and primers specific for the human beta-globin gene demonstrated the absence of inhibitors in these preparations. The incorporation of primers specific for Y. pestis rpoB (the RNA polymerase beta-subunit-encoding gene) and the recognized virulence-associated pla (the plasminogen activator-encoding gene) repeatedly yielded products that had a nucleotide sequence indistinguishable from that of modern day isolates of the bacterium. The specific pla sequence was obtained from 6 of 12 plague skeleton teeth but 0 of 7 negative controls (P plague was achieved for historically identified victims, and we have confirmed the presence of the disease at the end of 16th century in France. Dental pulp is an attractive target in the quest to determine the etiology of septicemic illnesses detected in ancient corpses. Molecular techniques could be applied to this material to resolve historical outbreaks.

  20. Rediscovering ancient glass technologies through the examination of opacifier crystals

    2008-07-01

    The aim of the study is to understand how antimonate opacifying crystals were obtained throughout history. Two archaeological glass productions opacified with calcium and lead antimonates are studied in this paper, in order to rediscover ancient opaque glass technologies: Roman mosaic tesserae (1st cent. B.C. 4th cent. A.D.) and Nevers lampworking glass (18th cent. A.D.). The fine examination of crystalline phases and of the vitreous matrix is undertaken using various and complementary techniques. Results are compared with a modern reference production, for which the technological process is well known. We demonstrate that Ca-antimonate opacifiers in Roman mosaic tesserae, as well as in Nevers lampworking glass, were obtained by in situ crystallization. Nevertheless, Roman and Nevers glass would have undergone different firing processes. We propose that the addition of previously synthesized crystals or the use of “anime” could be the process used to obtain Pb-antimonate opacified glass, for both productions studied. We demonstrate that CaO, PbO and Sb2O3 concentrations in the bulk compositions and in the matrices, and their evolution with the crystallinity ratio, offer robust criteria for the distinction of the opacification process used. Also, the different crystalline structures help to provide information on the experimental conditions.

    Humans around the globe probably discovered natural remedies against disease and cancer by trial and error over the millennia. Biomolecular archaeological analyses of ancient organics, especially plants dissolved or decocted as fermented beverages, have begun to reveal the preliterate histories of traditional pharmacopeias, which often date back thousands of years earlier than ancient textual, ethnohistorical, and ethnological evidence. In this new approach to drug discovery, two case studies from ancient Egypt and China illustrate how ancient medicines can be reconstructed from chemical and archaeological data and their active compounds delimited for testing their anticancer and other medicinal effects. Specifically, isoscopoletin from Artemisia argyi, artemisinin from Artemisia annua, and the latter's more easily assimilated semi-synthetic derivative, artesunate, showed the greatest activity in vitro against lung and colon cancers. In vivo tests of these compounds previously unscreened against lung and pancreatic cancers are planned for the future.

    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

  5. Dating ancient monuments by nuclear radiation

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

    Full Text Available Vlastimir Trajković (b. 1947 is a prominent Serbian composer with a strong inclination towards subjects from ancient Greek mythology. Among his most important achievements may be counted Arion - le nuove musiche per chitarra ed archi (1979 and Zephyrus returns for flute, viola and piano (2003. Two important aspects of those works are discussed in the present article: 1. the line that connects them to ancient Greek culture via French Modernism (Debussy, Ravel, Messiaen and Renaissance poetry and music (Petrarch, Caccini, Monteverdi; 2. modality, which has proved its vitality through long periods of the history of European music, beginning with ancient Greek modes, reaching its high point in the 16th century, and re-emerging at the beginning of the 20th century in different hybrid forms. Trajković is seen as a composer who has shaped his creative identity by exploring the rich musical heritage of the Latin European nations, especially the contributions of Debussy and Ravel.

    Full Text Available The practice of medical and surgical measures in the management of urological ailments prevailed in ancient India from the Vedic era around 3000 BC. Subsequently in the Samhita period, the two stalwarts - Charaka in medicine and Susruta in surgery elevated the art of medicine in India to unprecedented heights. Their elaboration of the etiopathological hypothesis and the medical and surgical treatments of various urological disorders of unparalleled ingenuity still remain valid to some extent in our contemporary understanding. The new generation of accomplished Indian urologists should humbly venerate the legacy of the illustrious pioneers in urology of our motherland.

    Ancient grain varieties have been shown to have some beneficial effects on health. Forty-five clinically healthy subjects were included in a randomized, double-blinded crossover trial aimed at evaluating the effect of a replacement diet with bread derived from ancient grain varieties versus modern grain variety on cardiovascular risk profile. After 8 weeks of intervention, consumption of bread obtained by the ancient varieties showed a significant amelioration of various cardiovascular parameters. Indeed, the ancient varieties were shown to result in a significant reduction of total cholesterol, low-density lipoprotein (LDL)-cholesterol and blood glucose, whereas no significant differences during the phase with the modern variety were reported. Moreover, a significant increase in circulating endothelial progenitor cells were reported after the consumption of products made from the ancient "Verna" variety. The present results suggest that a dietary consumption of bread obtained from ancient grain varieties was effective in reducing cardiovascular risk factors.

In several chapters the curiously forgotten history of fire-lighting technology is outlined, and it is demonstrated that "Tællelyset" is written by a person with a modern perspective on how to light a candle - among other things. The central argument in the book springs...... from a point-by-point tracing of 'the origins and history' of Hans Christian Andersen's famous fairy tales. Where did the come from? How did they become the iconic texts that we know today? On this background it becomes quite clear that "Tællelyset" is a modern pastiche and not a genuine Hans Christian...

    Tuberculosis is known to have afflicted humans throughout history and re-emerged towards the end of the 20th century, to an extent that it was declared a global emergency in 1993. The aim of this study was to apply a rigorous analytical regime to the detection of Mycobacterium tuberculosis complex (MTBC) DNA in 77 bone and tooth samples from 70 individuals from Britain and continental Europe, spanning the 1st-19th centuries AD. We performed the work in dedicated ancient DNA facilities designed to prevent all types of modern contamination, we checked the authenticity of all products obtained by the polymerase chain reaction, and we based our conclusions on up to four replicate experiments for each sample, some carried out in an independent laboratory. We identified 12 samples that, according to our strict criteria, gave definite evidence for the presence of MTBC DNA, and another 22 that we classified as "probable" or "possible." None of the definite samples came from vertebrae displaying lesions associated with TB. Instead, eight were from ribs displaying visceral new bone formation, one was a tooth from a skeleton with rib lesions, one was taken from a skeleton with endocranial lesions, one from an individual with lesions to the sacrum and sacroiliac joint and the last was from an individual with no lesions indicative of TB or possible TB. Our results add to information on the past temporal and geographical distribution of TB and affirm the suitability of ribs for studying ancient TB. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available The ancient mining landscape of Schwaz/Brixlegg in the Tyrol, Austria witnessed mining from prehistoric times to modern times creating a first order cultural landscape when it comes to one of the most important inventions in human history: the production of metal. In 1991 a part of this landscape was lost due to an enormous landslide that reshaped part of the mountain. With our work we want to propose a digital workflow to create a 3D semantic representation of this ancient mining landscape with its mining structures to preserve it for posterity. First, we define a conceptual model to integrate the data. It is based on the CIDOC CRM ontology and CRMgeo for geometric data. To transform our information sources to a formal representation of the classes and properties of the ontology we applied semantic web technologies and created a knowledge graph in RDF (Resource Description Framework. Through the CRMgeo extension coordinate information of mining features can be integrated into the RDF graph and thus related to the detailed digital elevation model that may be visualized together with the mining structures using Geoinformation systems or 3D visualization tools. The RDF network of the triple store can be queried using the SPARQL query language. We created a snapshot of mining, settlement and burial sites in the Bronze Age. The results of the query were loaded into a Geoinformation system and a visualization of known bronze age sites related to mining, settlement and burial activities was created.

  18. Lateral Gene Transfer Dynamics in the Ancient Bacterial Genus Streptomyces.

    Lateral gene transfer (LGT) profoundly shapes the evolution of bacterial lineages. LGT across disparate phylogenetic groups and genome content diversity between related organisms suggest a model of bacterial evolution that views LGT as rampant and promiscuous. It has even driven the argument that species concepts and tree-based phylogenetics cannot be applied to bacteria. Here, we show that acquisition and retention of genes through LGT are surprisingly rare in the ubiquitous and biomedically important bacterial genus Streptomyces Using a molecular clock, we estimate that the Streptomyces bacteria are ~380 million years old, indicating that this bacterial genus is as ancient as land vertebrates. Calibrating LGT rate to this geologic time span, we find that on average only 10 genes per million years were acquired and subsequently maintained. Over that same time span, Streptomyces accumulated thousands of point mutations. By explicitly incorporating evolutionary timescale into our analyses, we provide a dramatically different view on the dynamics of LGT and its impact on bacterial evolution. IMPORTANCE Tree-based phylogenetics and the use of species as units of diversity lie at the foundation of modern biology. In bacteria, these pillars of evolutionary theory have been called into question due to the observation of thousands of lateral gene transfer (LGT) events within and between lineages. Here, we show that acquisition and retention of genes through LGT are exceedingly rare in the bacterial genus Streptomyces , with merely one gene acquired in Streptomyces lineages every 100,000 years. These findings stand in contrast to the current assumption of rampant genetic exchange, which has become the dominant hypothesis used to explain bacterial diversity. Our results support a more nuanced understanding of genetic exchange, with LGT impacting evolution over short timescales but playing a significant role over long timescales. Deeper understanding of LGT provides new

    Full Text Available En el presente artículo los autores ensayan una aproximación a la realidad tenística en tanto que metáfora de la modernidad y la postmodernidad (también llamada hipermodernidad. Sabido es que los orígenes del tenis se remontan a una época premoderna, cuando se conocía como jeu de paume, práctica de gran éxito durante el Antiguo Régimen. Se sostiene que este deporte permite reflexionar en torno a un conjunto de valores y características de nuestras sociedades actuales. La moda, la tecnología, la diversidad sexual y étnica, el espectáculo, la publicidad, la aceleración, el erotismo, el éxito y el fracaso o el capitalismo globalizado aparecen como componentes imprescindibles para poder captar el fenómeno tenístico en toda su amplitud. Igualmente, la historia del tenis puede servir para ilustrar como a través del deporte se puede comprender la evolución socio-cultural de la civilización occidental. --------------------------------------------In this paper, the authors investigate an approach to the practice of tennis as a metaphor of modernity and post-modernity (also called hypermodernity. It is a wellknown fact that the origins of tennis go back to pre-modern times, when it was known as jeu de paume and widely practiced during the Ancient Regime. The autors, argue that this sport enables reflection on a series of values and features of modern society. Fashion, technology, sexual and ethnic diversity, spectacle, advertising, acceleration, eroticism, success and failure or globalised capitalism emerge as indispensable elements for understanding the tennis phenomenon in all its breadth. Likewise, the history of tennis may also illustrate how the sociocultural evolution of Western civilisation can be understood through spor.
