    Deng, Kehui

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

    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...

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

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

    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

    1997-01-01

    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

    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.

    2008-12-01

    Changes in key traits occurring during the processes of plant domestication have long been subjects of debate. Only in the case of genetic analysis or with extensive plant remains can specific sets of changes be documented. Historical details of the plant domestication processes are rare and other evidence of morphological change can be difficult to obtain, especially for those vegetables that lack a substantial body of archaeological data. Botanical records chronicled in the ancient literature of established ancient civilizations, such as that of China, are invaluable resources for the study and understanding of the process of plant domestication. Here, the considerable body of ancient Chinese literature is used to explore the domestication process that has occurred with the eggplant (Solanum melongena), an important vegetable in Old World. Information about eggplant domestication in the ancient Chinese literature was retrieved using a variety of methods. The information obtained was then sorted by taxon, examined and taxonomic identifications verified. It was found that the earliest record of the eggplant documented in ancient Chinese literature was in a work from 59 bc. As far as is known, this is the earliest reliable and accurately dated record of eggplant in cultivation. The analysis reveals that the process of domestication of the eggplant in China involved three principal aspects of fruit quality: size, shape and taste. These traits were actively and gradually selected; fruit size changed from small to large, taste changed from not palatable to what was termed at the time sweetish, and that over time, a wider variety of fruit shapes was cultivated. The results indicate that, in addition to data gleaned from archaeology and genetics, evidence as to changes in key traits occurring during the process of plant domestication and selective forces responsible for these changes can be traced through the ancient literature in some civilizations.

    Funo, Shuji

    2017-01-01

    Measurement systems are very important in urban design. This article reviews the theories of grid plans, particularly with respect to the spatial formations of ancient capital cities in Asia, and clarifies three Chinese Capital Models. The "Zhōu lǐ" Capital Model (Z) is based on the ancient text "Zhōu lǐ" that makes mention of the ideal city. However, because the description of the physical plan of the city is very brief and includes contradictory elements, conclusions regarding the specifics of the city design are extremely difficult to reach. This article proposes the most appropriate Model (Z) as an architype of the ideal Chinese city. Interestingly, there are no excavated examples of Model (Z). The two existing models, the Chang'an Capital Model (C), which is well known as the model for ancient Japanese capitals like Heiankyo (the present Kyoto) and the Dà Yuán (Dadu) Capital Model (D), the model for the city that is today Beijing, are described as Variants I and II, with a focus on the land division system of bo (street blocks).

    Proton induced X-ray emission (PIXE) is a well-known method for elemental analysis in many different specimens for various applied studies. In this paper, we report an application of PIXE analysis for a series of ancient Chinese coins from the Tang Dynasty to the Ming Dynasty (AD 618-1679). Ninety-six PIXE spectra were obtained from forty-eight samples of the ancient coins with the use of a Ge(Li) X-ray detector. On each sample two spots at different positions on the flat surface were irradiated per run by 3 MeV protons from a NEC 9SDH-2 pelletron tandem accelerator. The principal component elements (Cu, Pb, Sn and Zn) and others (Fe, Sb, Ni and As) were determined for the analyzed coins. Variations in composition with a time span of about one thousand years for the examined coins were observed. The results are presented and aspects of the evolution of Chinese metallurgy in casting coins are discussed. (orig.)

    Dissociative symptoms and disorders have been reported in many different cultures. If pathological dissociation is naturally occurring and related to adverse experiences, such phenomena should have been witnessed and portrayed before the modern age. To investigate whether this is the case, the author made use of the rich ancient Chinese medicine literature and looked for descriptions of pathological dissociation in medical documents written by ancient Chinese medical practitioners. In this paper, the author presents six cases selected from the ancient Chinese medicine literature. The phenomenon of pathological dissociation is observed in these cases. This is the first report of case descriptions of pathological dissociation documented in Chinese cultures before 1900.

    2005-01-01

    We have obtained unequivocal fingerprinting for many Chinese porcelains of utmost significance, based on high-precision multi-element and isotopic analysis by inductively-coupled mass spectrometry (ICP-MS) and thermal ionization mass spectrometry (TIMS) in our laboratory. As most ancient Chinese kilns used raw materials mined from local areas, differences in the geochemistry and mineralogy of these raw materials are expected to be preserved as distinctive geochemical and isotopic signatures in finished products and this may be useful for identifying their sources. Production techniques, such as purifying and mixing of different raw materials, may also vary from kiln to kiln, or may even change over time. All of that could also potentially leave a characteristic chemical and isotopic signature in a kiln's finished products. Using a tiny amount (often a few tens milligrams) of porcelain material, more than 40 element concentrations and Sr-Nd isotopic compositions can be rapidly and precisely determined on the ICP-MS and TIMS, respectively. The analytical results show that visibly similar Chinese porcelains made in different places and/or dynasties are strikingly distinctive. The data also allow modern fakes to be readily distinguished from antique porcelains. (author). 4 refs., 7 figs

    Structure analysis of Honglvcai, an overglaze ploychrome porcelain produced in China from the Song Dynasty to Ming Dynasty, has been a blank in studies on ancient Chinese ceramics. This work was focused on the oxidation state and local environment of colorants in red, yellow and green decorations on Honglvcai by X-ray absorption fine structure (XAFS). The analysis of Fe K-edge XANES and EXAFS spectra of the red-colored samples indicated that Fe 3+ was mainly located at a distorted octahedral site in a hematite phase, while that if the yellow-colored samples showed that iron was present as both trivalent and divalent cations coordinated with oxygen atoms in an amorphous phase. And Cu K-edge XAFS analysis of the green-colored samples revealed that Cu 2+ was the main constituent coordinated with oxygen atoms in an amorphous phase. (authors)

    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.)

    Eleven pieces of ancient Chinese pottery (4770 B.C. - 2960 B.C.) of Yangshao Culture Period collected from the Xi'an area have been studied by means of Moessbauer spectroscopy. The samples were refired up to 1100 0 C in steps of 100 0 C for 2 h in air. The highest temperature up to which the Moessbauer pattern remains basically unchanged can be identified with the original firing temperature. The result indicates that the firing temperatures for most of the sherds were between 900-1000 0 C. The function of the grit contained in the pottery has been discussed. The crimson and reddish painted materials on the surface of sherds have been studied, respectively. The first appearance of pottery can probably be traced back to an even earlier period. (orig.)

    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

    Ancient Chinese music bells, which have oval-like cross sections, possess the unique feature of a short sound-decay time that is especially suitable for music with fast tempo. Although recorded in the literature nearly 1000 years ago, this feature has never been truly understood. Recent damping measurement of oval pipes with different axial ratios suggested a challenging task for acousticians as the increase of the modal damping with the pipe's axial ratio is significant only when the pipe response is measured in air but not in vacuum. In this paper, the decrease of sound-decay time of oval pipes with the increased cross-section ovality is investigated. This is the first time that such short sound-decay feature is explained in terms of the rich sound radiation characteristics of the symmetric modes of music bells and the oval pipes. Finite element and boundary element methods are employed to explain how axial ratio significantly affects the normal velocity distribution, radiation efficiency, and directivity of acoustic modes.

    Rhinoplasty is one of the most delicate procedures in plastic and reconstructive surgery. Precision in every millimeter is vital in ensuring a better quality of surgical outcome. Many methods have been developed to fulfill this requirement. One such method is an implant, whether autogenous or artificial. Artificial implants involve several surgical complications, such as recipient rejection of implant material, infections, and rigid feel of the nasal tip. Hence, autogenous implants were eventually more widely applied, with material being obtained from the septum, concha, or rib cartilages. Therefore, the authors developed a new technique of rhinoplasty, using the osteochondral rib as an autogenous implant based on the ancient Chinese architectural technology called the DouGong method. The authors hereby present the results of 288 patients treated in our faculty wherein the data from the patients and the preoperative and postoperative 3-dimensional computed tomography scans were processed using Mimics software. The uniqueness of these implants is that the joint between the nasal dorsum and the columella strut is fixated without any screw, stitches, or K-wire. This procedure proved to be very useful as this technique not only minimized the application of fixation techniques, but also helped achieve a better nasofrontal angle, nasolabial angle, and columella length. After monitoring follow-ups of our patients, the authors hereby propose the use of this DouGong-based novel technique to improve the overall quality and outcome of corrective rhinoplasty.

    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

    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.

    Dating ancient Chinese porcelain is one of the most important and difficult problems in porcelain archaeological field. Eighteen elements in bodies of ancient celadon porcelains fired in Southern Song to Yuan period (AD 1127-1368) and Ming dynasty (AD 1368-1644), including La, Sm, U, Ce, etc., were determined by neutron activation analysis (NAA). After the outliers of experimental data were excluded and multivariate normal distribution was tested, and Bayesian classification was used for dating of 165 ancient celadon porcelain samples. The results show that 98.2% of total ancient celadon porcelain samples are classified correctly. It means that NAA and Bayesian classification are very useful for dating ancient porcelain. (authors)

    2017-01-01

    Cannabis sativa L. (Cannabaceae) has a long history of utilization as a fiber and seed crop in China, and its achenes ("seeds") as well as other plant parts have been recorded in Chinese medical texts for nearly 2000 years. While the primary applications of cannabis in Chinese medicine center around the use of the achenes, ancient indications for the female inflorescence, and other plant parts include conditions such as pain and mental illness that are the subject of current research into cannabinoids such as cannabidiol (CBD) and Δ 9 -tetrahydrocannabinol (THC). However, little previous research has been conducted to analyze the Chinese medical literature in light of recent advances in the pharmacology and taxonomy of cannabis, and most of the relevant Chinese historical records have not yet been translated into Western languages to facilitate textual research. Furthermore, many key questions remain unresolved in the Chinese literature, including how various traditional drug names precisely correspond to different plant parts, as well as the implications of long-term selection for fiber-rich cultivars on the medical applications of cannabis in Chinese medicine. In this article, prominent historical applications of cannabis in Chinese medicine are chronologically reviewed, and indications found in ancient Chinese literature that may relate to cannabinoids such as CBD and Δ 9 -THC are investigated.

    The donkey (Equus asinus) is an important domestic animal that provides a reliable source of protein and method of transportation for many human populations. However, the process of domestication and the dispersal routes of the Chinese donkey are still unclear, as donkey remains are sparse in the archaeological record and often confused with horse remains. To explore the maternal origins and dispersal route of Chinese donkeys, both mitochondrial DNA D-loop and cytochrome b gene fragments of 21 suspected donkey remains from four archaeological sites in China were amplified and sequenced. Molecular methods of species identification show that 17 specimens were donkeys and three samples had the maternal genetic signature of horses. One sample that dates to about 20,000 years before present failed to amplify. In this study, the phylogenetic analysis reveals that ancient Chinese donkeys have high mitochondrial DNA diversity and two distinct mitochondrial maternal lineages, known as the Somali and Nubian lineages. These results indicate that the maternal origin of Chinese domestic donkeys was probably related to the African wild ass, which includes the Nubian wild ass (Equus africanus africanus) and the Somali wild ass (Equus africanus somaliensis). Combined with historical records, the results of this study implied that domestic donkeys spread into west and north China before the emergence of the Han dynasty. The number of Chinese domestic donkeys had increased primarily to meet demand for the expansion of trade, and they were likely used as commodities or for shipping goods along the Silk Road during the Tang Dynasty, when the Silk Road reached its golden age. This study is the first to provide valuable ancient animal DNA evidence for early trade between African and Asian populations. The ancient DNA analysis of Chinese donkeys also sheds light on the dynamic process of the maternal origin, domestication, and dispersal route of ancient Chinese donkeys.

    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

    Acupuncture has been widely used in China for three millennia as an art of healing. Yet, its physiology is not yet understood. The current interest in acupuncture started in 1971. Soon afterward, extensive research led to the concept of neural signaling with possible involvement of opioid peptides, glutamate, adenosine and identifying responsive parts in the central nervous system. In the last decade scientists began investigating the subject with anatomical and molecular imaging. It was found that mechanical movements of the needle, ignored in the past, appear to be central to the method and intracellular calcium ions may play a pivotal role. In this review, we trace the technique of clinical treatment from the first written record about 2,200 years ago to the modern time. The ancient texts have been used to introduce the concepts of yin, yang, qi, de qi, and meridians, the traditional foundation of acupuncture. We explore the sequence of the physiological process, from the turning of the needle, the mechanical wave activation of calcium ion channel to beta-endorphin secretion. By using modern terminology to re-interpret the ancient texts, we have found that the 2nd century B.C.: physiologists were meticulous investigators and their explanation fits well with the mechanistic model derived from magnetic resonance imaging (MRI) and confocal microscopy. In conclusion, the ancient model appears to have withstood the test of time surprisingly well confirming the popular axiom that the old wine is better than the new.

    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.

    In ancient china, according to the local natural environment, a variety of drainage facilities were built in order to excrete rainwater, domestic sewage, production wastewater and so on. These drainage facilities were mainly made of pottery, bricks, wood, stone, etc. For example, ceramic water pipelines, buried in the ground, connect together one by one, and there was a slight drop from one end to the other in favor of drainage. These measures can also be used for reference in today’s urban drainage and flood control.

    The identification and localization of organic binders in artworks are big challenges in archaeology and conservation science. Immunological techniques, such as enzyme-linked immunosorbent assay (ELISA) and immunofluorescence microscopy (IFM) have the potential to become powerful tools for the analysis of organic materials in ancient samples. In this study, ELISA and IFM techniques were combined to identify chicken ovalbumin, glue from several mammalian species, bovine milk, and fish glue in ancient Chinese painting samples. As binders, egg ovalbumin was found in two painting samples and animal glue was found in three samples, which were dated from the 4th to 8th centuries. The results clearly demonstrate that ELISA and IFM can be used to validate results from ancient samples.

    Ancient Di-Qiang people once resided in the Ganqing region of China, adjacent to the Central Plain area from where Han Chinese originated. While gene flow between the Di-Qiang and Han Chinese has been proposed, there is no evidence to support this view. Here we analyzed the human remains from an early Di-Qiang site (Mogou site dated ~4000 years old) and compared them to other ancient DNA across China, including an early Han-related site (Hengbei site dated ~3000 years old) to establish the underlying genetic relationship between the Di-Qiang and ancestors of Han Chinese. We found Mogou mtDNA haplogroups were highly diverse, comprising 14 haplogroups: A, B, C, D (D*, D4, D5), F, G, M7, M8, M10, M13, M25, N*, N9a, and Z. In contrast, Mogou males were all Y-DNA haplogroup O3a2/P201; specifically one male was further assigned to O3a2c1a/M117 using targeted unique regions on the non-recombining region of the Y-chromosome. We compared Mogou to 7 other ancient and 38 modern Chinese groups, in a total of 1793 individuals, and found that Mogou shared close genetic distances with Taojiazhai (a more recent Di-Qiang population), Hengbei, and Northern Han. We modeled their interactions using Approximate Bayesian Computation, and support was given to a potential admixture of ~13-18% between the Mogou and Northern Han around 3300-3800 years ago. Mogou harbors the earliest genetically identifiable Di-Qiang, ancestral to the Taojiazhai, and up to ~33% paternal and ~70% of its maternal haplogroups could be found in present-day Northern Han Chinese.

    To sum up the application regularity of Fengfu (GV 16) acupoint in clinical practice through studying the ancient literature from the early stage of the Qin Dynasty to the Qing Dynasty. Chinese ancient medical literature relevant to Fengfu (GV 16) was searched to establish a database containing information of clinical indications of GV 16, supplementary acupoints, relevant needling techniques, moxibustion methods, etc. A total of 277 articles about Fengfu (GV 16) for 61 types of clinical disorders or diseases involving internal medicine, surgery, paediatrics, five sense organs, etc. were obtained from 2,200 ancient Chinese medical books. Fengfu (GV 16) alone was most frequently used for treatment of disorders caused by exogenous factors, such as common cold, neck pain, headache, epilepsy, mania, dizziness, throat dumb, leg-foot problems, etc. , with the auxiliary acupoint being Fengchi (GB 20). In addition, 147 articles relevant to needling and moxibustion stimulation of GV 16 (7 types of methods) were found. Fengfu (GV 16) is mainly used for local problems in the human body, and also for problems occurred along the meridian trace, aiming at the pathogenesis. When employed, GV 16 is often stimulated by acupuncture needle.

    It is important to identify pigments of painting and colored drawing in ancient architectures in order to restore and conserve them. The components of green pigments were detected with X-ray diffraction (XRD), X-ray fluorescence (XRF) and scanning electron microscopy-energy dispersive X-ray (SEM-EDX). Twenty-seven samples were collected from painting and colored drawing in northern Chinese ancient architectures in Beijing, Shanxi province and Gansu province. The experiment results showed that emerald green [CuCH3COO]2 x Cu(AsO2)2], a complex of copper aceto-arsenite pigment, had been used as the colored component in fifteen samples, whereas organic materials synthesized in the rest. However, in all samples there were no malachite and atacamite, green pigments commonly used in ancient time a long time ago. These two pigments have been found in Qin Shihuang's Terracotta Army and the wall paintings at Mogao Grettoes, Dunhuang, and some other famous wall paintings and color pottery figurines. However, emerald green was used many years later. It was reported that emerald green was synthesized by Germany in 1814 and had been widely used in China as watercolor on pith paper works and on scroll paintings since the 1850s. Because painting and colored drawing in ancient architectures stands outside, under sunlight and rain, it must be repaired and repainted in less than fifty years. Therefore, it is not surprising that emerald green was used in them. In recent years, artificial organic materials are increasingly used in painting and colored drawing in ancient architectures. From experiments it was also showed that in the same recolored painting and colored drawing, organic materials are usually in the later layers, but emerald green is in the earlier layers. This work supplies a lot of data for the purpose of selecting restoration materials and identifying painting and colored drawing in ancient architectures with a new method.

    Problem-based learning (PBL) has been widely adopted as a strategy by nurse educators all over the world. Many studies have been carried out to examine its process and outcomes. There are few studies discussing the relevance of PBL to students with different cultural background. This study reports the experiences of Chinese students in Hong Kong using PBL and explores if their experiences were compatible with the educational philosophy documented in traditional Chinese literature. The phenomenological approach was used in the treatment of data. The informants were students enrolled in the post-registration nursing degree programme at a university in Hong Kong during 1997-1998. A total of 94 journals were included in the analysis. Seven main themes emerged from the phenomenological analysis. They were the integration of knowing and doing, critical reflection and debate, individuality of learning, self-motivated learning, critical inquiry and independent thinking, timeliness of instruction and cooperative learning. This study provides evidence to show that PBL is an approach that is compatible with the Chinese way of learning. The result of this study shows that aspects of the modern PBL process harken back to an ancient Chinese learning philosophy that underpins Chinese learning today.

    Sericulture is one of the great inventions of the ancient Chinese. Besides the mulberry silkworm (Bombyx mori), Chinese farmers developed rearing of the Chinese oak silkworm (Antheraea pernyi) about 400 years ago. In this paper, the historic records of the origins and dispersal of the domesticated Chinese oak silkworm in China are summarized. The first document with clearly recorded oak silkworm artificial rearing appeared in 1651, although Chinese oak silkworm was documented in about 270 AD. All of the evidence in the available historic records suggests that the domesticated Chinese oak silkworm originated in central and southern areas of Shandong Province in China around the 16th century, and then was introduced directly and indirectly by human commerce into the present habitations in China after the late 17th century. The results strongly support the hypothesis that only one geographically distinct event occurred in domestication of the modern Chinese oak silkworm.

    The objectives of this research are, first, to establish if the extraordinary acupuncture meridian known as Chōng, Penetrating Vessel or Sea of Blood, is in essence a description of certain macroscopic parts of the underlying vascular system and, second, by extension, to show that it is likely that cadaveric dissection would have been used as a tool to arrive at this understanding. Generally accepted scholarly opinion holds that the ancient Chinese rarely used dissection in order to explore the anatomy of the human body, and that the meridians are therefore invisible metaphysical structures corresponding to lines drawn on the body. However, the seminal text, 'The Yellow Emperor's Classic of Internal Medicine', describes using palpation to examine the living and dissection to examine the dead. This implies that the original authors of these texts were observing physical structures visible to the naked eye. Dissection has therefore been used to compare the descriptions of the Chōng meridian in 'The Yellow Emperor's Classic of Internal Medicine' with the vascular anatomy of the human body. Fifteen acupuncture points located on various different ordinary meridians but bearing the same name, Chōng, were also examined to see if they bore any relationship to the vascular system. The dissections clearly show that the Chōng meridian correlates to certain main blood vessels in the body, in particular the vena cava. Similarly, most Chōng acupuncture points have a strong correspondence with blood vessels, marking terminal arteries on the hands, feet and forehead and anastomoses on the face, body and feet. These findings strongly suggest that the ancient Chinese texts relating to this meridian are likely to have been a 'description' of the vascular system. Furthermore, the ancient Chinese apparently had a high degree of anatomical skill in the practice of dissection and acute powers of observation. Published by the BMJ Publishing Group Limited.

    The single-aliquot regenerative-dose (SAR) protocol with optically stimulated luminenscence (OSL) was applied to measure the equivalent dose (ED) of ancient Chinese bricks ranging in age from 180 to 1600 years. In the protocol, sensitivity changes can be corrected by using OSL response to a fixed test dose during measurement. For comparative study between OSL and TL, thermoluminescence (TL) measurement procedures were also applied to determine the paleodose of the bricks. Both results of OSL and TL are in agreement with the known ages of the bricks, and the paleodose ratios(ED OSL / ED TL ) are between 0.96 and 1.21, mean value 1.08+/-0.02. The annual doses of the bricks, estimated by the paleodoses and the known ages, range from 5.07 to 6.79mGy/a, comparable with the measured annual dose values of the bricks. Therefore, it is concluded that the SAR protocol is a rapid and effective OSL technique to authenticate Chinese bricks

    The single-aliquot regenerative-dose (SAR) protocol to the optically stimulated luminescence (OSL) was applied to measure the paleodose of ancient Chinese bricks with an age range from 180 to 1600 years. In the protocol, sensitivity changes can be corrected by using OSL response to a fixed test dose during measurement. For comparative study between OSL and TL, thermoluminescence (TL) measurement procedures were also applied to determine the paleodose of the bricks. Both results of OSL and TL are in good agreement with, and the paleodose ratios (De OSL /De TL ) are between 0.96 and 1.21, with a mean value of 1.08 ± 0.07. The annual dose of the bricks, estimated by the paleodoses and the known ages, ranges from 5.07 to 6.85 mGy/a, comparable with the measured annual dose values. Therefore, it is concluded that the SAR protocol is a rapid and effective OSL technique to authenticate Chinese bricks. (authors)

    Dens invaginatus (DI) is a developmental anomaly of teeth. Here we observed the characteristics of DI in 517 permanent teeth from 67 ancient Chinese people using micro-computed tomography (micro-CT) scanning techniques. The individuals were excavated from Shaanxi province of China and identified to be about 2,000 years old. Four DI categories are proposed to distinguish the different types of DI. The invaginated lingual fossa is classified into three classes. The overall prevalence of DI in 67 individuals was 31.34% (21 of 67). DI was found in 25 of 517 teeth (4.83%). All affected teeth were maxillary lateral incisors. The invaginated lingual fossa (Type I DI) occurred most frequently (84%), followed by radicular grooves (Type II; 16%), while Type III and Type IV were not found in the present study. Some of fossae correspond with radicular grooves (8 of 21; 3 located at mesial, 5 were distal). The bilateral incidence of DI was 19.05%. Comparing our results to those of a retrospective survey of DI from 1873 to present, we found a higher rate of DI in the excavated teeth of Chinese individuals 2,000 years ago. The use of the micro-CT technique and ethnic origin might have contributed to the higher incidence of DI. Copyright © 2013 Wiley Periodicals, Inc.

    Full text: The objective of this work was to contribute to the demonstration of the long term safety of low-and-intermediate level radioactive waste (LILW) disposal using information from a natural analogue study on ancient Chinese constructions. The work firstly compared LILW near surface disposal facilities with Chinese ancient tombs in respects of siting, engineering structures, design and construction procedures and indicates that they are both based upon multi-barrier principle. After extensive literature and field survey, three materials were collected from two Chinese ancient tombs and one ancient architectures for further laboratory study. The three materials were studied in laboratories from the point of view of radioactive waste disposal in near surface facilities to obtain information concerning their basic physical and chemical properties, engineering properties and radionuclide adsorption abilities. The results show that the two materials from the ancient tombs have low permeability and strong adsorption for 60 Co and 134 Cs. The saturated permeabilities of the two ancient materials are in the order of 10 -1 0 m/s and the distribution coefficients for the two radionuclides are all in the order of 10 1 m 3 /kg. The conclusion was that the then current LILW disposal option in near-surface would be effective for a long term period of time, and clay materials, as backfill materials for LILW near-surface disposal facilities would very effective in preventing water intrusion and retarding radionuclide release even over a long term of period. Overall the LILW disposal option was considered to be safe in long term. (author)

    The Chinese crude drug Qiang-hua was listed as an alias of Du-hua in Shen-nong-ben-cao-jing, an herbal journal written during the Han Dynasty, China. Du-hua and Qiang-hua are recognized as different herbs in China these days; the main botanical origin of Du-hua is Angelica spp. and that of Qiang-hua is Notopterygium spp., of the family Umbelliferae. To make clear the botanical origins of Du-hua and Qiang-hua in ancient China, the authors made a herbological study. The findings were as follows: the name of Qiang-hua was given to the genuine Du-hua, which is produced in Qiang Province, an ancient province located in northwest China; the botanical origin of Qiang-hua is presumed to be Notopterygium incisum Ting ex H.T. Chang and N. forbesii Boissieu based on both the morphology and habitat written in ancient herbal journals. Both species are prescribed as having the plant origin of Qiang-hua in the present Chinese Pharmacopoeia. Therefore, we concluded that Du-hua and Qiang-hua were essentially the same drug, and were originally derived from the Notopterygium species in ancient China.

    Nondestructive analysis of historical objects is of significance for cultural heritage conservation. In this paper, terahertz time-domain spectroscopy (THz-TDS) was used to distinguish seven red mineral pigments used in ancient Chinese artworks. Two absorption features of natural minerals HgS and four highly resolved spectral features of mineral pigment Pb3O4 were observed and identified as their fingerprints in the range 0.2 to 3.0 THz, based on which the spatial distribution of individual chemical substances including cinnabar, vermilion, and red lead were clearly revealed at various frequencies using terahertz spectroscopy imaging. Moreover, a noncontact evaluation of thickness changing and dehydration of a wet painting was monitored by inferring time delay as well as signal amplitude of THz pulses transmitted through the painting. In order to demonstrate the feasibility of THz-TDS and THz imaging for authentic artworks detection, a complete set of THz analysis of two nineteenth century wall paintings discovered in the Fuchen Temple of the Forbidden City, Beijing, was performed and the results indicate that THz measurement techniques provide a noninvasive and nondestructive solution for the care, preservation, and restoration of cultural relics.

    Shards of ancient Chinese white porcelain, which were excavated at Maojiawan in the city of Beijing, were analyzed by instrumental neutron activation analysis (INAA). These shards were fired in the period between the Yuan (AD 1271-1368) and Ming (AD 1368-1644) dynasties at Jingdezhen in southern China. According to the analytical results, different raw materials were used for making porcelain body in this period. Fe and Na are the characteristic elements which can be used for identifying the specific date of these porcelains. Furthermore, shards of Hongwu era (AD 1368-1398), Yongle-Xuande era (AD 1403-1435) and Chenghua-Zhengde era (AD 1465-1561) of the Ming dynasty can be clearly distinguished by their elemental body composition. The temporal chemical variation in the porcelain body of these eras is observed. The elemental body composition of Zhengde-Tianshun era (AD 1436-1464) is mainly similar to that of the Hongwu and Yongle-Xuande eras. The temporal chemical feature of Zhengtong-Tianshun era was not found.

    Full Text Available Researchers are paying increasing attention to questions of community leadership and rural tourism development. Based on leadership theories and the literature on community leadership and tourism development, this study developed a framework for community leadership in rural tourism development and used it to examine two ancient Chinese villages. We used the longitudinal case study method to collect data, and we used textual analysis to analyze these data. The results show that the rebel leadership characteristic of confrontational actions played an important role in starting the tourism industry in both villages. However, this leadership was difficult to maintain because community leaders and residents had limited power compared to that of outsiders. Losing control of tourism development in the two villages led to banal management, which prevented the emergence of strong community leadership. In the future, we argue that resilient community leadership should be nurtured in the two villages to address more complex problems occurring in tourism development, such as those characterized by vision tensions and conflicts of interest among the stakeholders affected by tourism development. Finally, we suggest that, based on the longitudinal method, future research can focus on the relationship between resilient leadership and the resilience of tourism communities.

    The Han Chinese are the largest ethnic group in the world, and their origins, development, and expansion are complex. Many genetic studies have shown that Han Chinese can be divided into two distinct groups: northern Han Chinese and southern Han Chinese. The genetic history of the southern Han Chinese has been well studied. However, the genetic history of the northern Han Chinese is still obscure. In order to gain insight into the genetic history of the northern Han Chinese, 89 human remains were sampled from the Hengbei site which is located in the Central Plain and dates back to a key transitional period during the rise of the Han Chinese (approximately 3,000 years ago). We used 64 authentic mtDNA data obtained in this study, 27 Y chromosome SNP data profiles from previously studied Hengbei samples, and genetic datasets of the current Chinese populations and two ancient northern Chinese populations to analyze the relationship between the ancient people of Hengbei and present-day northern Han Chinese. We used a wide range of population genetic analyses, including principal component analyses, shared mtDNA haplotype analyses, and geographic mapping of maternal genetic distances. The results show that the ancient people of Hengbei bore a strong genetic resemblance to present-day northern Han Chinese and were genetically distinct from other present-day Chinese populations and two ancient populations. These findings suggest that the genetic structure of northern Han Chinese was already shaped 3,000 years ago in the Central Plain area. PMID:25938511

  2. Semantic 3D Modeling Based on CityGML for Ancient Chinese-Style Architectural Roofs of Digital Heritage

    Full Text Available Ancient Chinese-style architecture has received increased attention during the last century as a segment of cultural heritage and is of great significance, specifically in regard to the process of digitizing and modeling these buildings to preserve and protect this heritage. Because the roof form reflects the age of the structure, the structural character and the historical culture of the ancient building, constructing a refined model for the roof is a primary aspect of the 3D modeling procedure. To avoid cumbersome traditional modeling approaches that use geometry units, such as points, lines and triangles, a flexible semantic method is proposed in this study to improve modeling efficiency and reduce the professional requirements. In this method, a two-level semantic decomposition of the roof is presented according to the characteristics of ancient Chinese-style architecture. The structural level reveals the basic components that determine its structural shape, and the decorative level refers to the attached components that influence the exterior appearance. The assembly validity of the decomposed elements and the combined diversity of the integrated entities are ensured by topological constraints and derived transformations of the semantic components. This proposed method was implemented by utilizing CityGML (City Geography Markup Language via the ADE (Application Domain Extension mechanism and was tested by modeling the principal buildings included in the Palace Museum.

    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.

    Neutron activation analysis (NAA) is an important technique to determine the provenance of ancient ceramics. The most common technique used for preparing ancient samples for NAA is to grind them into a powder and then encapsulate them before neutron irradiation. Unfortunately, ceramic materials are typically very hard making it a challenge to grind them into a powder. In this study we utilize bulk porcelain samples cut from ancient shards. The bulk samples are irradiated by neutrons alongside samples that have been conventionally ground into a powder. The NAA for both the bulk samples and powders are compared and shown to provide equivalent information regarding their chemical composition. Also, the multivariate statistical have been employed to the analysis data for check the consistency. The findings suggest that NAA results are less dependent on the state of the porcelain sample, and thus bulk samples cut from shards may be used to effectively determine their provenance. (author)

    This article describes the complementary application of non-invasive micro-Raman spectroscopy and energy dispersive X-ray fluorescence spectrometry to the characterization of some ancient Chinese silicate artifacts. A total of 28 samples dated from fourth century BC to third century AD were analyzed. The results of chemical analysis showed that the vitreous PbO-BaO-SiO2 material was used to sinter these silicate artifacts. The barium copper silicate pigments including BaCuSi4O10, BaCuSi2O6 and BaCu2Si2O7 were widely identified from colorful areas of the samples by Raman spectroscopy. In addition, other crystalline phases such as Fe2O3, BaSi2O5, BaSO4, PbCO3 and quartz were also identified. The present study provides very valuable information to trace the technical evolution of man-made barium copper silicate pigments and their close relationship with the making of ancient PbO-BaO-SiO2 glaze and glass.

    2014-04-01

    A great amount of research has been carried out world-wide to promote history of science as a powerful science teaching tool. Because the ways of choosing and using historical elements depend on teachers' or researchers' educational purpose, any attempt to support a single model-to-use seems difficult and probably irrelevant. However, specific purposes may reflect specific and prescriptive terms for using historical materials. Our work aims to show up this aspect. It is an attempt to make elements of the history of astronomy involved in the elaboration of a training session for future primary school teachers. Here, ancients' Greek and Chinese historical elements are chosen and organized according to specific educational and conceptual constraints that include the construction of the quasi-parallelism of solar rays reaching Earths' surface, and the spontaneous modeling of the propagation of Sunlight leaning on divergent rays. This leads to an original teaching sequence were historical elements are mixed with non historical ones. This organization forms the support of a pre-service training session developed for future primary school teachers. This session aims to provide future teachers with elementary cosmological knowledge (parallelism of Sunrays, shape and size of the Earth, Sun-Earth distance…), to provide some reference marks of history of ancient cosmologies (spherical and flat Earth) resulting from two distinct contexts, and to approach some aspects associated with Nature of Science (NOS).

    Some analytic technique can play important role for identifying the provenance and age of ceramic ware. However, it is usually not allowed to destructive analyze for a valuable intact porcelain ware. These analysis methods such as X-ray Fluorescence (XRF), Proton Induced X-ray Emission (PIXE), and Synchrotron Radiation X-ray Fluorescence (SRXRF) are suitable for nondestructive analysis of ancient ceramic wares. In order to compare the analytic data obtained by different measuring method and identify the provenance and age accurately, the effective way is to calibrate elemental concentration in body and glaze of ceramic ware. Microanalysis reference material (MRM) of ancient ceramic has to be prepared for achieving quantitative analysis. A solid powder 99% in size of 500 mesh for microanalysis reference material (MRM) has being prepared in institute of high energy physics. The minimum analytic masses of 1 mg were determined by Neutron Activation Analysis (NAA) for these elements (Sc, Cr, Co, Rb: Cs, La, Ce, Nd, Sm, Tb, Yb, Lu; Hf, Ta, Th, U), and by SRXRF for elements (K, Ca, Ti, Mn, Fe, Zn; Rb, Sr).

  12. The Accuracy of the Five-planet Locations Calculated by the Chinese Ancient Calendar Named Shoushi Li

    2011-01-01

    The calendar Shoushi Li is one of the most famous calendars in ancient China, which was recorded in the Lizhi (ancient calendar book of China) of Yuanshi (annals of the Yuan Dynasty from 1279 to 1367). There are seven important calculation parts, including solar terms, syzygies, corrections of the sun and the moon, eclipses and so on. The locations of the five-planet are also in the list. Almost every part has a corresponding section in the modern astronomical year book. It is the last calendar formulated only by Chinese astronomers and its period of usage (from 1281 to 1644) is the longest one in ancient China. It was also a new calendar system which cast off the traditional method by which calculations were carried out from the epoch of the distant past. The basic constants were obtained by meticulous observations and then used in calculations. In this paper, the calculation methods of planetary locations in Shoushi Li are investigated and recovered by studying the official texts of Yuanshi. (1) The locations of the ephemeris of Jupiter in 1299 are derived and our recovering method is affirmed by comparing with other studies. (2) The calculated accuracies of celestial longitudes of the five-planet from 1280 to 1650 are obtained. For Jupiter, Mars, Saturn, Venus and Mercury, the average values of absolute errors are 0.49°, 1.91°, 0.70°, 2.82° and 5.01°. Jupiter and Saturn have comparatively higher accuracies. (3) Zhoulu, Lilu, Dulu, Heying and Liying are used for planetary calculations in Shoushi Li. Their accurate values, instead of those adopted in Shoushi Li, are derived and calculated by modern astronomical methods and then inputted into Shoushi models. It is found that the accuracies of planetary locations are not improved. The errors of Jupiter and Saturn are 1.83°and 1.21°. But the errors of Mercury, Venus and Mars ascend to 30.04°, 54.86°and 10.82°, respectively. It is indicated that the accuracies can not be increased by revising some of the

    The Chinese ancient black mirror known as Heiqigu was studied by x-ray-absorption near-edge structure spectroscopy and results were reported. The Sn-L 3 edge and Fe K edge spectra further confirmed the Schottky-type defect model in the Heiqigu surface system. And it was suggested that the surface layer of the mirror was a combined structure of oxidation of Sn(IV) and Sn(II). (authors)

    Traditional Chinese Medicine (TCM) serves as the most common alternative therapeutic approach for Western medicine and benefits IBS patients globally. Due to the lack of scientific evidence in the past, TCM formulas were not internationally well recognized as promising IBS remedies. In this review, firstly, we present the etiology and therapy of IBS in terms of traditional Chinese medical theory. Secondly, we summarize the clinical randomized controlled trials (RCTs) of TCM formulas for IBS patients that are available in the literature (from 1998 to September 2013), in which 14 RCTs conducted of high quality were discussed in detail. Of the 14 selected trials, 12 of those concluded that TCM formulas provided superior improvement in the global symptoms of IBS patients over the placebo or conventional medicines. As well, all 14 RCTs suggested that TCM formulas have good safety and tolerability. Last but not least, we explore the pharmacological mechanisms of the anti-IBS TCM formulas available in the literature (from 1994 to September, 2013). Collectively, in combating IBS symptoms, most TCM formulas exert multi-targeting actions including the regulation of neurotransmitters and hormones in the enteric nervous system (ENS), modulation of smooth muscle motility in the gastrointestinal (GI) tract, modulation of the hypothalamic-pituitary-adrenal (HPA) axis, attenuation of intestinal inflammation and restoration of intestinal flora, etc. In conclusion, TCM formulas appear to be promising for IBS treatment. This review provides a useful reference for the public in furthering a better understanding and acceptance of TCM formulas as IBS remedies.

    Full Text Available Ternary clay-based composite material (TCC, composed of lime, clay and sand, and usually modified with sticky rice and other organic compounds as additives, was widely used historically in Chinese construction and buildings due to its high mechanical performance. In this study, to gain an insight into the micromechanical mechanism of this cementitious material, the nanomechanical properties and volume fraction of mechanically different phases of the binder matrix are derived from the analysis of grid nanoindentation tests. Results show that there are five distinct mechanical phases, where the calcium silicate hydrate (C-S-H and geopolymer present in the binder matrix are almost identical to those produced in ordinary Portland cement (OPC and alkali-activated fly-ash geopolymer materials in nano-mechanical performance. The nano-mechanical behavior of calcite produced by the carbonation of lime in this binder is close to the calcite porous outer part of some sea urchin shells. Compared to OPC, the C-S-H contained in the TCC has a relatively lower ratio of indentation modulus to indentation hardness, implying a relatively lower resistance to material fracture. However, the geopolymer and calcite, at nearly the same volume content as the C-S-H, help to enhance the strength and durability of the TCC by their higher energy resistance capacity or higher strength compared to the C-S-H. Rediscovering of TCC offers a potential way to improve modern concrete’s strength and durability through synergy of multi-binders and the addition of organic materials if TCC can be advanced in terms of its workability and hardening rate.

    This paper draws together two important agendas in science education. The first is making science education more inclusive such that students from non-Western or indigenous cultures can benefit from culturally relevant curricula. The second is integrating technology into the curriculum under the umbrella of Science-Technology-Society (STS) education to embrace the social aspects of science, with technology serving as a bridge. The advancement of the first agenda is hindered by the pursuance by both Western and non-Western societies of narrow cultural and practical goals without considering the development of science and technology from a cross-cultural perspective. The second agenda is limited by the misconception that technology is applied science, leading to the exclusion from STS discussions of pre-science or indigenous technologies developed by non-Western cultures. Through selected case studies of the evolution of Chinese traditional technologies and their interaction with science, this paper offers a perspective from the Far East, and argues for situating culturally responsive science education in broader historical and cross-cultural contexts to acknowledge the multi-cultural contributions to science and technology. A form of cross-cultural STS education is advanced, encompassing the cultural basis of technological developments, technology diffusion, interactions of traditional technology with science, and the potential development of traditional or indigenous technologies. This approach provides a bridge between the existing universal science education paradigm promoted in the West and the different forms of multi-cultural education advocated by indigenous science educators. To translate theory into practice, a conceptual framework is proposed in which the essential transdisciplinary knowledge base, curricular goals, and pedagogical approaches are embedded.

    In addition to the collected books in the General Catalog of Ancient Chinese Medical Books, there are lots of acu-moxibustion literature of the Republic of China period scattered among the people which are not carried in this Catalog, some of them are rare and precious ones. In 1933, the first issue of Acu-moxibustion Journal was published and became the first professional Journal of acupuncture and moxibustion in China, 35 issues were published at that time, with many monographs on acu-moxibustion carried in its "special column". Meanwhile, other acupuncturists from different regions also established acu-moxibustion associations or schools and edited all kinds of acupuncture moxibustion teaching materials in order to develop acu-moxibustion education. In a word, the acu-moxibustion literature of the Republic of China were not only rich in forms and contents, but also combined with regional characteristics. Therefore, it should be pay more attention on that field and do further study.

  1. Trepanation in Ancient China.

    2017-05-01

    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.

    Cathy W C Bi

    Full Text Available Fo Shou San (FSS is an ancient herbal decoction comprised of Chuanxiong Rhizoma (CR; Chuanxiong and Angelicae Sinensis Radix (ASR; Danggui in a ratio of 2:3. Previous studies indicate that FSS promotes blood circulation and dissipates blood stasis, thus which is being used widely to treat vascular diseases. Here, we aim to determine the cellular mechanism for the vascular benefit of FSS. The treatment of FSS reversed homocysteine-induced impairment of acetylcholine (ACh-evoked endothelium-dependent relaxation in aortic rings, isolated from rats. Like radical oxygen species (ROS scavenger tempol, FSS attenuated homocysteine-stimulated ROS generation in cultured human umbilical vein endothelial cells (HUVECs, and it also stimulated the production of nitric oxide (NO as measured by fluorescence dye and biochemical assay. In addition, the phosphorylation levels of both Akt kinase and endothelial NO synthases (eNOS were markedly increased by FSS treatment, which was abolished by an Akt inhibitor triciribine. Likewise, triciribine reversed FSS-induced NO production in HUVECs. Finally, FSS elevated intracellular Ca(2+ levels in HUVECs, and the Ca(2+ chelator BAPTA-AM inhibited the FSS-stimulated eNOS phosphorylation. The present results show that this ancient herbal decoction benefits endothelial function through increased activity of Akt kinase and eNOS; this effect is causally via a rise of intracellular Ca(2+ and a reduction of ROS.

    The Fe K-edge X-ray absorption near-edge structure (XANES) spectra of a series of ceramic shards were measured by fluorescence mode to reveal the color-generating techniques of Chinese porcelain. The analysis disclosed relationships among the chemical form of the iron, the firing conditions and the colors of the ceramics. The results indicate that the coloration for different ceramics depend on the valence states of iron as the main color element in glaze and the proportion of Fe 2+ and Fe 3+ was attributed to the baking technology. The findings provide important information for archaeologist on the coloration researches.

    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.

    Increased levels of reactive oxygen species (ROS) are a crucial pathogenic factor of osteoporosis. Gastrodin, isolated from the traditional Chinese herbal agent Gastrodia elata, is a potent antioxidant. We hypothesized that gastrodin demonstrates protective effects against osteoporosis by partially reducing reactive oxygen species in human bone marrow mesenchymal stem cells (hBMMSCs) and a macrophage cell line (RAW264.7 cells). We investigated gastrodin on osteogenic and adipogenic differentiation under oxidative stress in hBMMSCs. We also tested gastrodin on osteoclastic differentiation in RAW264.7 cells. Hydrogen peroxide (H2O2) was used to establish an oxidative cell injury model. Our results showed that gastrodin significantly promoted the proliferation of hBMMSCs, improved some osteogenic markers, reduced lipid generation and inhibited the mRNA expression of several adipogenic genes in hBMMSCs. Moreover, gastrodin reduced the number of osteoclasts, TRAP activity and the expression of osteoclast-specific genes in RAW264.7 cells. Gastrodin suppressed the production of reactive oxygen species in both hBMMSCs and RAW264.7 cells. In vivo, we established a murine ovariectomized (OVX) osteoporosis model. Our data revealed that gastrodin treatment reduced the activity of serum bone degradation markers, such as CTX-1 and TRAP. Importantly, it ameliorated the micro-architecture of trabecular bones. Gastrodin decreased osteoclast numbers in vivo by TRAP staining. To conclude, these results indicated that gastrodin shows protective effects against osteoporosis linking to a reduction in reactive oxygen species, suggesting that gastrodin may be useful in the prevention and treatment of osteoporosis.

    Oxidative damage plays a critical role in the etiology of neurodegenerative disorders including Parkinson's disease (PD). In our study, an ancient Chinese kidney-tonifying formula, which consists of Cistanche , Epimedii, and Polygonatum cirrhifolium , was investigated to protect MES23.5 dopaminergic neurons against hydrogen peroxide- (H 2 O 2 -) induced oxidative damage. The damage effects of H 2 O 2 on MES23.5 cells and the protective effects of KTF against oxidative stress were evaluated using MTT assay, transmission electron microscopy (TEM), immunocytochemistry (ICC), enzyme-linked immunosorbent assay (ELISA), and immunoblotting. The results showed that cell viability was dramatically decreased after a 12 h exposure to 150  μ M H 2 O 2 . TEM observation found that the H 2 O 2 -treated MES23.5 cells presented cellular organelle damage. However, when cells were incubated with KTF (3.125, 6.25, and 12.5  μ g/ml) for 24 h after H 2 O 2 exposure, a significant protective effect against H 2 O 2 -induced damage was observed in MES23.5 cells. Using ICC, we found that KTF inhibited the reduction of the tyrosine hydroxylase (TH) induced by H 2 O 2 , upregulated the mRNA and protein expression of HO-1, CAT, and GPx-1, and downregulated the expression of caspase 3. These results indicated that KTF may provide neuron protection against H 2 O 2 -induced cell damage through ameliorating oxidative stress, and our findings provide a new potential strategy for the prevention and treatment of Parkinson's disease.

    2009-11-01

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

    Chemical composition of ancient coins may be useful to know the provenance of raw ore materials, technique of minting, route of circulation, and governmental policy or economical conditions of the epoch when they were minted. Thirteen elements (major: Cu, Pb, Sn, Zn, minor: Fe, As, Sb, trace: Co, Mn, Ni, Au, Ag, Se) in Chinese and Japanese ancient coins were determined by inductively coupled plasma-optical emission spectroscopy and instrumental neutron activation analysis. The results show that, in both Chinese and Japanese coins, a transition from Cu-Pb-Sn system to Cu-Zn system occurred in the 15 -- 16 th century in China and in the 18 th century in Japan. Compositional ranges in Cu-Pb-Sn coins extend to 50 -- 80% Cu, 15 -- 35% Pb and 6 -- 15% Sn, respectively, and there seems to be no systematic compositional change with a function of their ages. As to the Cu-Zn coins, the Cu to Zn ratio of Chinese coins is distinctly different from that of Japanese ones, being about unity for Chinese coins and 4 for Japanese ones. In general, Japanese coins are much more abundant in As and Sb than Chinese ones. It is an important problem whether they are impurities of major elements or some components intentionally added in the course of minting. (author)

    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

    Danggui Buxue Tang (DBT) is an ancient Chinese herbal decoction containing two herbs, Astragali Radix (AR) and Angelicae Sinensis Radix (ASR): this herbal decoction serves as dietary supplement for women during menopause. DBT has been known to modulate immune responses, and its polysaccharide is proposed to be one of the active components. However, the polysaccharide-induced signaling in immune activation is not revealed. Here, we are identifying that the immune activation, triggered by DBT, could be mediated by polysaccharide. In cultured macrophages (RAW 264.7 cells), the application of polysaccharide-enriched extract of DBT significantly increased the expressions of mRNA and protein levels of interleukin-1β, interleukin-6 and tumor necrosis factor. The induction was much stronger than the polysaccharide extract generated singly from AR, or from ASR, or from their simple mixture. The induced cytokine release in cultured macrophage was revealed to be triggered by activation of nuclear factor-kappa B (NF-κB) signaling, including (i) degradation of IkBα; (ii) translocation of NF-κB p65 from cytosol to nuclei; and (iii) activation of NF-κB transcriptional elements. These results verified the possible role of DBT polysaccharide in modulating immune responses. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

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

  5. Searching for events in Chinese ancient records to explain the increase in 14C from AD 774-775 and AD 993-994

    According to analysis of the 14C content in two Japanese trees, that grew over a period of approximately 3000 years, with high time resolution, Miyake et al. found a rapid increase at AD 774-775 and another one at AD 993-994. These increases correspond to high-energy events that happened within those years and radiated γ-ray energy of about 7×1024 erg toward the Earth. The origin of these events is a mystery. Such strong events should have an unusual optical counterpart, and have been recorded in historical literatures. We searched Chinese historical materials around AD 744-775 and AD 993-994, but no remarkable event was found except for a violent thunderstorm in AD 775. However, the possibility of a thunderstorm containing so much energy is unlikely. We conclude that the events, which caused the 14C increase, are still unclear. These events most probably had no optical counterpart, and a short gamma-ray burst, giant flare of a soft gamma-ray repeater or a terrestrial γ-ray flash could all be candidates.

    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.

    The most important discovery, which enriched our knowledge of ancient astronomy in Armenia, was the complex of platforms for astronomical observations on the Small Hill of Metzamor, which may be called an ancient “observatory”. Investigations on that Hill show that the ancient inhabitants of the Armenian Highlands have left us not only pictures of celestial bodies, but a very ancient complex of platforms for observing the sky. Among the ancient monuments in Armenia there is a megalithic monument, probably, being connected with astronomy. 250km South-East of Yerevan there is a structure Zorats Kar (Karahunge) dating back to II millennium B.C. Vertical megaliths many of which are more than two meters high form stone rings resembling ancient stone monuments - henges in Great Britain and Brittany. Medieval observations of comets and novas by data in ancient Armenian manuscripts are found. In the collection of ancient Armenian manuscripts (Matenadaran) in Yerevan there are many manuscripts with information about observations of astronomical events as: solar and lunar eclipses, comets and novas, bolides and meteorites etc. in medieval Armenia.

    The earliest industrial biotechnology originated in ancient China and developed into a vibrant industry in traditional Chinese liquor, rice wine, soy sauce, and vinegar. It is now a significant component of the Chinese economy valued annually at about 150 billion RMB. Although the production methods had existed and remained basically unchanged for centuries, modern developments in biotechnology and related fields in the last decades have greatly impacted on these industries and led to numerous technological innovations. In this chapter, the main biochemical processes and related technological innovations in traditional Chinese biotechnology are illustrated with recent advances in functional microbiology, microbial ecology, solid-state fermentation, enzymology, chemistry of impact flavor compounds, and improvements made to relevant traditional industrial facilities. Recent biotechnological advances in making Chinese liquor, rice wine, soy sauce, and vinegar are reviewed.

  16. Tuberculosis in ancient times

    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

  17. Dentistry in ancient mesopotamia.

    Neiburger, E J

    2000-01-01

    Sumer, an empire in ancient Mesopotamia (southern Iraq), is well known as the cradle of our modern civilization and the home of biblical Abraham. An analysis of skeletal remains from cemeteries at the ancient cities of Ur and Kish (circa 2000 B.C.), show a genetically homogeneous, diseased, and short-lived population. These ancient Mesopotamians suffered severe dental attrition (95 percent), periodontal disease (42 percent), and caries (2 percent). Many oral congenital and neoplastic lesions were noted. During this period, the "local dentists" knew only a few modern dental techniques. Skeletal (dental) evidence indicates that the population suffered from chronic malnutrition. Malnutrition was probably caused by famine, which is substantiated in historic cuneiform and biblical writings, geologic strata samples, and analysis of skeletal and forensic dental pathology. These people had modern dentition but relatively poor dental health. The population's lack of malocclusions, caries, and TMJ problems appear to be due to flat plane occlusion.

    2011-01-01

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

  11. Acupuncture in ancient China: how important was it really?

    Science.gov (United States)

    Lehmann, Hanjo

    2013-01-01

    Although acupuncture theory is a fundamental part of the Huangdi Neijing, the clinical application of the needle therapy in ancient China was always a limited one. From early times there have been warnings that acupuncture might do harm. In books like Zhang Zhongjing's Shanghanlun it plays only a marginal role. Among the 400 emperors in Chinese history, acupuncture was hardly ever applied. After Xu Dachun called acupuncture a "lost tradition" in 1757, the abolition of acupuncture and moxibustion from the Imperial Medical Academy in 1822 was a radical, but consequent act. When traditional Chinese medicine was revived after 1954, the "New Acupuncture" was completely different from what it had been in ancient China. The conclusion, however, is a positive one: The best time acupuncture ever had was not the Song dynasty or Yuan dynasty, but is now - and the future of acupuncture does not lie in old scripts, but in ourselves.

  12. Linen in Ancient Egypt

    Directory of Open Access Journals (Sweden)

    dr.Rehab Mahmoud Ahmed Elsharnouby

    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.

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

    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.

    International Nuclear Information System (INIS)

    Jiang, W.; Roy, D.M.

    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

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

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

    2012-12-01

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

    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...

  5. Motion sickness in ancient China: Seasickness and cart-sickness.

    Brandt, Thomas; Bauer, Matthias; Benson, Judy; Huppert, Doreen

    2016-07-19

    To find and analyze descriptions of motion sickness in Chinese historical sources. Databases and dictionaries were searched for various terms for seasickness and travel sickness, which were then entered into databases of full texts allowing selection of relevant passages from about the third to the 19th century ad. Already in 300 ad the Chinese differentiated cart-sickness, particularly experienced by persons from the arid north of China, from a ship-illness experienced by persons from the south, where rivers were important for transportation and travel. In the Middle Ages, a third form of motion sickness was called litter-influence experienced by persons transported in a bed suspended between 2 long poles. The ancient Chinese recognized the particular susceptibility of children to motion sickness. Therapeutic recommendations include drinking the urine of young boys, swallowing white sand-syrup, collecting water drops from a bamboo stick, or hiding some earth from the middle of the kitchen hearth under the hair. The Chinese medical classics distinguished several forms of travel sickness, all of which had their own written characters. The pathophysiologic mechanism was explained by the medicine of correspondences, which was based on malfunctions within the body, its invasion by external pathogens like wind, or the deficit or surfeit of certain bodily substances such as the life force Qi. The concept of motion as the trigger of sickness initially appeared in a chapter on warding off the influence of demons and corpses, e.g., ancient magic and beliefs. © 2016 American Academy of Neurology.

  6. The Populist Dream of Chinese Democracy

    2015-01-01

    Mainstream Chinese discussions of “democracy” have long betrayed a decidedly populist understanding of the concept. Xi Jinping draws freely on this tradition in formulating his China Dream. Xi’s efforts are part of the Chinese Communist Party’s “re-Orientation” of official propaganda to showcase the glories of the ancient civilization that it claims to represent and rejuvenate. This populist interpretation of “democracy” seeks to elide the fundamental contradiction between Enlightenment value...

    Full Text Available Recent analyses of ancient Mesopotamian mitochondrial genomes have suggested a genetic link between the Indian subcontinent and Mesopotamian civilization. There is no consensus on the origin of the ancient Mesopotamians. They may be descendants of migrants, who founded regional Mesopotamian groups like that of Terqa or they may be merchants who were involved in trans Mesopotamia trade. To identify the Indian source population showing linkage to the ancient Mesopotamians, we screened a total of 15,751 mitochondrial DNAs (11,432 from the literature and 4,319 from this study representing all major populations of India. Our results although suggest that south India (Tamil Nadu and northeast India served as the source of the ancient Mesopotamian mtDNA gene pool, mtDNA of these ancient Mesopotamians probably contributed by Tamil merchants who were involved in the Indo-Roman trade.

  10. Ancient Greek new music

    Directory of Open Access Journals (Sweden)

    Martin Žužek

    2000-12-01

    Full Text Available In this article I use a contextual approach to questions about the revolutionary »new music« in ancient Greece. This view is different from the nowadays most common formalistk view. Rather than analyze textual sources stylistically, I will try to present the available lata in the context of the structure and events of the Athenian society at a tirne when a wave of »new« poetics appeared. In the following discussion it is argued that the »new music« and the phenomena of the destruction of mousiké connected with it are not an esthetical novum, but more a consequence of the change of the discursive practice, where a musical poetry became less important and needless.

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

    Writing from the numismatist point of view, the authors open this paper by reviewing critically the use of scientific methods for the studies of ancient coins. They also report about an application of the PIXE method at low incident proton energy to one of the most celebrated and known coinage in the ancient history: the Athenian silver coins of the fifth century BC. The results of those analyses indicate that the metallic composition of several coins usually taken as ancient imitations of Athenian coins does not differ from that of the genuine ones. Those analyses confirm what the authors have inferred from numismatic sources: These coins are probably genuinely Athenian

    Full Text Available During the beginning of the XXth century, China suffered attacks from foreign powers causing the lost of parts of its territory as well as a challenge to its national pride. The traditional Chinese martial arts were unable to defeat the tactics and modern weaponry that China’s enemies had in their arsenal. Despite the overwhelming odds, the Chinese forces made use of their ingenuity and adapted the ancient weapons and fighting skills succeeding to some extent in slowing down the enemy’s advance. This period witnessed the last time cold weapons would play an important role in modern Chinese warfare.

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

    2014-01-01

    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. The subject is open for further research.

    The analysis of ancient DNA is playing an increasingly important role in conservation genetic, phylogenetic and population genetic analyses, as it allows incorporating extinct species into DNA sequence trees and adds time depth to population genetics studies. For many years, these types of DNA...... analyses (whether using modern or ancient DNA) were largely restricted to the analysis of short fragments of the mitochondrial genome. However, due to many technological advances during the past decade, a growing number of studies have explored the power of complete mitochondrial genome sequences...... (mitogenomes). Such studies were initially limited to analyses of extant organisms, but developments in both DNA sequencing technologies and general methodological aspects related to working with degraded DNA have resulted in complete mitogenomes becoming increasingly popular for ancient DNA studies as well...

    Amber is a plant resin mainly produced by coniferous trees that, after entrapping a variety of living beings, was subjected to a process of fossilization until it turned into yellowish, translucent stones. It is also one of the best sources of ancient DNA on which to perform studies on evolution. Here a method for the sterilization of amber that allows reliable ancient DNA extraction with no actual DNA contamination is described. Working with insects taken from amber, it was possible to amplify the ATP9, PGU1 and rRNA18S ancient genes of Saccharomyces cerevisiae corresponding to samples from the Miocene and Oligocene. After comparison of the current genes with their ancient (up to 35-40 million years) counterparts it was concluded that essential genes such as rRNA18S are highly conserved and that even normal 'house-keeping' genes, such as PGU1, are strikingly conserved along the millions of years that S. cerevisiae has evolved.

    The ancient teacher-disciple tradition is regarded as one of the most celebrated practices within the Chinese medicine world. Such traditions of secrecy, private wisdom and honor are deeply rooted in the theories of Confucianism. This paper only explores the surface of this ancient culture, by investigating relevant popular ancient texts and common Chinese proverbs, as well as utilizing personal experiences, in order to reflect on how the ancient Chinese perceived such practices within their own society and how secret teaching was passed on from teacher to student, including the revelation of secret formulas and their importance and how that tradition differs from our modern-day perspectives. Various rare manuscripts from the author's personal library are employed in order to provide relative examples of the importance of secret knowledge, and how these secrets applied in the traditional healing.

    Dreams preoccupied the Greek and Roman world in antiquity, therefore they had a prominent role in social, philosophical, religious, historical and political life of those times. They were considered as omens and prophetic signs of future events in private and public life, and that was particularly accentuated when elements of actions which took place in the plot of dreams were associated directly or indirectly with real events. This is why it was important to use them in divination, and helped the growth of superstition and folklore believes. Medicine as a science and an anthropocentric art, could not ignore the importance of dreams, having in mind their popularity in antiquity. In ancient Greek medicine dreams can be divided into two basic categories. In the first one -which is related to religious medicine-dreams experienced by religionists are classified, when resorted to great religious sanctuaries such as those of Asclepius (Asclepieia) and Amphiaraos (Amfiaraeia). These dreams were the essential element for healing in this form of religious medicine, because after pilgrims underwent purifications they went to sleep in a special dwelling of the sanctuaries called "enkoimeterion" (Greek: the place to sleep) so that the healing god would come to their dreams either to cure them or to suggest treatment. In ancient Greek literature there are many reports of these experiences, but if there may be phenomena of self-suggestion, or they could be characterized as propaganda messages from the priesthood of each sanctuary for advertising purposes. The other category concerns the references about dreams found in ancient Greek medical literature, where one can find the attempts of ancient Greek physicians to interpret these dreams in a rational way as sings either of a corporal disease or of psychological distress. This second category will be the object of our study. Despite the different ways followed by each ancient Greek physician in order to explain dreams, their

    2010-01-01

    Full Text Available The aim of this review is to highlight emerging trends about Chinese people and gambling addiction over the last 15 years, and to provide a discourse on the potential link between gambling and Chinese culture and history. The authors reported on the phenomenon of gambling among Chinese people using relevant research studies and reports and traditional Chinese literature. Chinese people have elevated levels of gambling addiction compared to their Western counterparts. These elevated rates are coupled with the rapid expansion of gambling venues within the Pan-Pacific region. While there is an accumulated body of research on Chinese and gambling, a systematic cultural analysis of Chinese gambling is still under development. We undertook a brief comparison between two ancient civilizations, China and Rome, in order to gain better understanding about gambling among Chinese people. To effectively deal with gambling addictions among Chinese people, it is imperative to develop culturally responsive interventions.

  15. Colour Perception in Ancient World

    Nesterov, D. I.; Fedorova, M. Yu

    2017-11-01

    How did the human thought form the surrounding color information into the persistent semantic images of a mythological, pseudoscientific and religious nature? The concepts associated with colour perception are suggested. The existence of colour environment does not depend on the human consciousness. The colour culture formation is directly related to the level of the human consciousness development and the possibility to influence the worldview and culture. The colour perception of a person goes through the stages similar to the development of colour vision in a child. Like any development, the colour consciousness has undergone stages of growth and decline, evolution and stagnation. The way of life and difficult conditions for existence made their own adjustments to the development of the human perception of the surrounding world. Wars have been both a powerful engine of progress in all spheres of life and a great destructive force demolishing the already created and preserved heritage. The surrounding world has always been interesting for humans, evoked images and fantasies in the consciousness of ancient people. Unusual and inexplicable natural phenomena spawned numerous legends and myths which was reflected in the ancient art and architecture and, accordingly, in a certain manifestation of colour in the human society. The colour perception of the ancient man, his pragmatic, utilitarian attitude to colour is considered as well as the influence of dependence on external conditions of existence and their reflection in the colour culture of antiquity. “Natural Science” conducts research in the field of the colour nature and their authorial interpretation of the Hellenic period. Several authorial concepts of the ancient world have been considered.

    Science.gov (United States)

    Tatsumi, Nami; Marui, Eiji

    2012-03-01

    The purpose of this thesis is to demonstrate that buckwheat has been recognized, both in Japan and China, as a crop that is useful in many ways: as an agricultural crop, and for the healing powers and properties that, according to traditional Chinese medicine, it has. A comparative study of ancient documents pertaining to medicine in these countries has made it clear that this is the case. Buckwheat, however, has been used quite differently in each country. As is shown in some ancient Chinese documents pertaining to medicine, China has treated buckwheat primarily as a medicine for clinical use rather than as an edible crop. Nowadays, buckwheat is eaten only in some regions of China. Although it came to Japan from China as a medicine, in Japan buckwheat gradually became a popular food crop. It has become an important component of traditional Japanese cuisine thanks in part to government support and the strong demand that developed in Japanese society.

    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.

    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.

  20. Lost-Wax Casting in Ancient China: New Discussion on Old Debates

    2015-07-01

    The possible use of lost-wax casting in China has long been a matter of controversy. Based on the study of pertinent ancient texts concerning the technical origins of lost-wax casting in China, direct examination of questioned ancient Chinese bronzes as well as definite lost-wax castings from both overseas and China, and modern production of objects using piece-mold casting, the authors point out their own conceptual ideas about ancient lost-wax casting as follows. First, the lost-wax casting technique does not have its earliest origins in ancient China but rather from the Sumerians in Mesopotamia, where it was predominantly used to cast small human and animal figures (statuettes). Next, some essential characteristics of the lost-wax casting technique can be identified from the point of view of a distortable soft starting model. The locally deformed shape of lost-wax castings is found to be variable. Finally, it is improper to consider the ease of extraction from the mold as the criterion for distinguishing lost-wax casting from piece-mold casting. It is therefore incorrect to conclude that the three-dimensional openwork decorations present on Chinese bronzes from the Spring and Autumn Period, and the Warring States Period, are fabricated using lost-wax castings.

    Chinese yew is a medicinal plant which has the largest planted area, better economic effects and ecological benefits in our country. People have insufficient appreciation of centuries-old historical document and abundant cultural connotation of Chinese yew, because Chinese yew had no name in ancient times and some expressions of western countries are still cited at present. Therefore, this paper did a great deal of analysis and reference works focusing on synonym and byname of ancient Chinese yew. Excavation and classification of historical documents of Chinese yew from ancient classics and bibliography had been done by studying 3 503 books, about billions of words been recorded in the Si Ku Quan Shu. These researches made up for simple and inadequate contents of many large tool books, like Chinese materia medica and traditional Chinese medicine, and so on. At the same time, in order to change the situation of no name, uncertain channel tropism, irregular functions of Chinese yew, its property and flavor, channel tropism, effects and functions had been summarized. History of the tumor treatment of Chinese yew had been traced back to the time of Tang Dynasty and this was almost 1 200 years earlier than western countries.

    Full Text Available Xenía was a special relationship between a foreign guest and his host in Ancient Greece. The ritual of hosting a foreigner included an exchange of objects, feasting, and the establishment of friendship between people from different social backgrounds. This relationship implied trust, loyalty, friendship, and mutual aid between the people involved. Goods and services were also exchanged without any form of payment. There were no formal laws governing xenía – it was based entirely on a moral appeal. Mutual appreciation between the host and the guest was established during the ritual, but the host did retain a certain level of superiority over the guest. Xenía was one of the most important institutions in Ancient Greece. It had a lot of features and obligations similar to kinship and marriage. In literary sources the word xénos varies in meaning from “enemy stranger”, “friendly stranger”, “foreigner”, “guest”, “host” to “ritual friend”, and it is often hard to tell which usage is appropriate in a given passage. The paper describes the emphasis on hospitality towards foreigners. It presents an example of a depiction indicating xenía is presented, as well as several objects which were traded during the ritual. The paper also addresses the importance of hospitality in Greek drama in general, especially with examples of violations of the hospitality code.

  9. Ancient Climatic Architectural Design Approach

    Full Text Available Ancient climatic architecture had found out a series of appropriate responses for the best compatibility with the critical climate condition for instance, designing ‘earth sheltered houses’ and ‘courtyard houses’. They could provide human climatic comfort without excessive usage of fossil fuel resources. Owing to the normal thermal conditions in the ground depth, earth sheltered houses can be slightly affected by thermal fluctuations due to being within the earth. In depth further than 6.1 meters, temperature alternation is minute during the year, equaling to average annual temperature of outside. More to the point, courtyard buildings as another traditional design approach, have prepared controlled climatic space based on creating the maximum shade in the summer and maximum solar heat absorption in the winter. The courtyard houses served the multiple functions of lighting to the rooms, acting as a heat absorber in the summer and a radiator in the winter, as well as providing an open space inside for community activities. It must be noted that they divided into summer and winter zones located in south and north of the central courtyard where residents were replaced into them according to changing the seasons. Therefore, Ancient climatic buildings provided better human thermal comfort in comparison with the use contemporary buildings of recent years, except with the air conditioning

    Chinese ancient porcelain history has lasted about three thousands years from Shang Dynasty (1100∼1600 BC). A large amount of ancient porcelain sherds with accuracy provenance and ages were excavated from a lot of kiln sites in China. Archaeologists and ceramic experts have recognized and researched it with excavated stratum, utensil shape, body quality, glaze color and painting pattern. However, the appearance characteristic of some ancient porcelain manufactured in different kilns is similar. Therefore, it is still difficult to identify the provenance and ages of the samples excavated from some sites using traditional methods. Up, to now, many problems of Chinese ancient porcelain are confused for archaeologist and collecting experts. The elemental composition of ancient porcelain shows certain information of provenance and age. Especially, the sorts and contents of the elements in porcelain didn't change, so it is very useful to determine the provenance of ancient porcelain with elemental composition characteristics. Provenance characteristic is the important scientific information to identify ancient porcelain wares excavated from sites and graves. The porcelain samples of Si-Long-Kou Yue kiln in Zhejiang Province of china have been analyzed with NAA in this paper. The provenance characteristic was compared with it of Hong-Zhou kiln of Jiang-Xi Province and Yao-Zhou kiln of Shan-Xi Province. The experimental data were studied with statistic methods. The results show that the chemical compositions of porcelain body samples for three kilns were different. The difference was been able identified. The porcelain body materials of both Si-Long-Kou Yue kiln and Hong-Zhou kiln of Jiang-Xi were similar. The samples of Yao-Zhou kiln in north of China existed obvious difference.

  17. Birth of Olympic flame: Ancient Greece and European identity (II

    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

    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

    2013-01-01

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

    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.

    Mortars sampled from Dutifulness Monument, where typical ancient China mortar formulas and manufacturing processes were used, were analyzed by starch-iodine test, FTIR, DSC-TG, SEM and XRD methods. Several modeling samples were then made according to historical records of Chinese ancient mortar formulas and analyzed with the same techniques. The modeling formulas also were used to consolidate loose specimens. The results show that sticky rice plays a crucial role in the microstructure and the consolidation properties of lime mortars. A possible mechanism was suggested that biomineralization may occur during the carbonation of calcium hydroxide, where the sticky rice functions as a template and controls the growth of calcium carbonate crystal. The organic-inorganic materials formed based on this mechanism will be more favorable for consolidating the loose samples both in strength improvement and durability

    Full Text Available Chinese ancient stone archways are in flat structure. And joints of their members are of half tenons and mortises. Under the influence of the earthquake, the resisting ability of archway’s uneven sides is relatively poor and the relevant members have little reliable joints. This paper is to analyze seismic strengthening feasibility of Tiantai mountain stone archway which is damaged from the earthquake and to research on the aspects of the loading mode, structure layout and soundness. On the premise of guaranteeing the authenticity and beauty, we use earthquake damaging mechanism of stone archways and the modern anti-seismic structure designing theory and modern building materials. We also follow the way of the modern construction technology and ancient construction and strengthen the anti-seismic way of the resisting ability of Tiantai mountain stone archway’s uneven sides and joints of tenons and mortises. The best anti-seismic strengthening schemes are put forward as well.

    Aesthetic psychology has discussed many aspects of aesthetic preferences for spatial composition. However, there have been few empirical explorations of the spatial composition of traditional Chinese paintings. The results of this experiment showed that the shape of the frame had a significant effect on aesthetic preferences. Participants preferred to put two figures at certain relative horizontal distances from each other according to the horizontal shape of the frame but may have difficulty in adapting the relative vertical distance according to the vertical shape of the frame. Furthermore, the unique aesthetic interest of traditional Chinese long-vertical scroll paintings was discussed. This discussion revealed that, in a creative way, ancient Chinese artists followed the same aesthetic principles we observed, and they developed the artistic conception and romantic charm of traditional Chinese paintings.

    The ancient Silk Road, a pioneering work in the history of human civilization, contributed greatly to the cultural exchange between China and the West. It is the precious cultural heritage should be shared by the whole humanity. Although there were countless archaeological sites along the ancient Silk Road, most of the existing researches just focused on the sites, lacking the overall understanding of the relationships between sites and their supporting environment. Space archaeology provides a new viewpoint for investigating, discovering, reconstructing and documenting the archaeological sites under different scales. The tuntian system was a state-promoted system of military-agricultural colonies, which originated in the Western Han dynasty (206 BC-9 AD). All the imperial dynasties in Chinese history adopted the practice of tuntian to cultivate and guard frontier areas as an important state policy for developing border areas and consolidating frontier defence. This study describes the use of Chinese GF-1 imagery, LS-7 ETM+ data and ASTER GDEMV2 products to uncover an ancient irrigated canal-based tuntian system located in Milan oasis adjacent to the ancient Kingdom of Loulan at the southern margin of the Tarim Basin. The GF-1 and LS-7 data were first processed following atmospheric and geometric correction and enhanced by Gram Schmidt pansharpening. The linear archaeological traces of tuntian irrigation canals were extracted from the morphologically enhanced GF-1 PAN imagery using our proposed automatic method which adopts mathematical morphological processing and Canny edge operator. Compared with the manual extractions, the overall detection accuracy was better than 90%. In addition, the functions of the trunk, primary, secondary and tertiary canals were each analyzed and the spatial extent of Milan's tuntian landscape were analyzed with the help of the NDVI derived from the GF-1 multispectral imagery. The effective irrigated tuntian area was estimated to be 2

    In this article, I argue that it is misleading to dichotomize the West as being either/or and the East as being both/and. The West has thought dialectically since ancient Greece. I offer a typology to compare and contrast three dialectical or non-either/or logical systems or ways of thinking......: Chinese Yin-Yang philosophy, Hegel's dialectic, and Niels Bohr's complementarity principle, as well as Aristotle's formal (either/or) logic. I show that the four logical systems have differences and similarities and show that Westerners can and do think dialectically. I also argue that Chinese Yin...... methods....

  20. The Ancient Martian Climate System

    Haberle, Robert M.

    2014-01-01

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

    2009-02-01

    Full Text Available Abstract Background Ancient schwannomas are degenerate peripheral nerve sheath tumors that very rarely occur in the retroperitoneum. They generally reach large proportions before producing symptoms due to mass effect. We describe three cases of retroperitoneal ancient schwannomas and discuss the diagnosis and management of these tumors. Case presentations Three female patients with retroperitoneal ancient schwannomas were reviewed. One patient presented with several weeks of upper abdominal pain and lower chest discomfort, whereas back pain and leg pain with associated weakness were predominant symptoms in the remaining two. Abdominal imaging findings demonstrated heterogeneous masses in the retroperitoneum with demarcated margins, concerning for malignancy. The patients successfully had radical excision of their tumors. Histological examination showed encapsulated tumors that displayed alternating areas of dense cellularity and areas of myxoid matrix consistent with a diagnosis of ancient schwannoma. Conclusion A diagnosis of ancient schwannoma should be entertained for any heterogeneous, well encapsulated mass in the retroperitoneum. In these cases less radical surgical resection should be considered as malignant transformation of these tumors is extremely rare and recurrence is uncommon following excision.

    Full Text Available Middle Chinese is thelanguage used in the period from the Eastern Han Dynasty to the Sui Dynasty. Inrecent years researches of Middle Chinese have attracted scholars’ attention.While it inherited some characteristics from the grammar of Ancient Chinese,the morphology and syntax of Middle Chinese underwent obvious elimination andnew birth, an important content which laid the foundation for the furtherevolution of the Early Modern Chinese Grammar. Numerous grammatical phenomenonstarted to appear in Tang and Song Dynasties. The grammar was going through achange in which new forms replaced old ones, thus being the mediator ininheriting the archaic and beginning the early modern grammar, and thereforeoccupying an important position in the history of Chinese.

    Full Text Available Diabetic retinopathy is one of the main causes of visual impairment and blindness on a global scale. At present, the limitations of anti-vascular endothelial growth factor agents, steroids, laser photocoagulation, and vitreous surgery have led to a growing awareness of the role of Chinese medicines in the treatment of diabetic retinopathy. This review first describes the ingredients and characteristics of the formulae including Chinese herbal formulaes, Chinese patent drugs and ancient processed drugs and summarizes the application of Chinese medicines and their mechanisms of action in the treatment of diabetic retinopathy. Due to the complexity of Chinese medicines, in-depth mechanisms, side effects of herb, and drug interactions need to be elaborated in future research. Chinese medicines have the potencial to protect the residual eyesight and delay the progression of disease, thereby offering a beneficial, exploitable option in the treatment/prevention of diabetic retinopathy.

    Full Text Available Ayurveda and other Indian system of medicine use metals, but their use is also amply described in Chinese and Egyptian civilization in 2500 B.C. Bhasma are unique ayurvedic metallic/minerals preparation, treated with herbal juice or decoction and exposed for Ayurveda, which are known in Indian subcontinent since 7 th century A.D. and widely recommended for treatment of a variety of chronic ailments. Animal′s derivative such as horns, shells, feathers, metallic, nonmetallic and herbals are normally administered as Bhasma. A Bhasma means an ash obtained through incineration; the starter material undergoes an elaborate process of purification and this process is followed by the reaction phase, which involves incorporation of some other minerals and/or herbal extract. There are various importance of Bhasma like maintaining optimum alkalinity for optimum health, neutralizing harmful acids that lead to illness; because Bhasma do not get metabolized so they don′t produce any harmful metabolite, rather it breakdowns heavy metals in the body. Methods including for Bhasma preparation are parpati, rasayoga, sindora, etc., Bhasma which contain Fe, Cu, S or other manufacturing process plays a specific role in the final product(s. Particle size (1-2 μ reduced significantly, which may facilitate absorption and assimilation of the drug into the body system. Standardization of Bhasma is utmost necessary to confirm its identity and to determine its quality, purity safety, effectiveness and acceptability of the product. But the most important challenges faced by these formulations are the lack of complete standardization by physiochemical parameters.

    2015-11-01

    Full Text Available The actual Romanian territory belongs to Carpatho-Danubian Space and to Ancient Europe. The Ancient European Society was a vast cultural entity based on a theocratic, matriarchal society, peaceful and art creating.Temples of Sarmizegetusa have given rise to several theories over time, proven by historians with the most diverse arguments. The largest complex of temples and sanctuaries was founded in Sarmizegetusa Regia, the Dacian’s main fortress and ancient capital of Dacia in the time of King Decebalus. The mysterious form of settlements has led researchers to the conclusion that the locations were astronomical observation shrines. Among the places of Dacian worship in Orastie Mountains the most impressive is the Great Circular Sanctuary, used to perform some celestial observations, and also as original solar calendar. This paper had the purpose to re-discover the Dacian Civilization and Dacian cosmogony based on the accumulated knowledge upon our country’s past.

  6. Prehistoric polymers: rubber processing in ancient mesoamerica

    Hosler; Burkett; Tarkanian

    1999-06-18

    Ancient Mesoamerican peoples harvested latex from Castilla elastica, processed it using liquid extracted from Ipomoea alba (a species of morning glory vine), and fashioned rubber balls, hollow rubber figurines, and other rubber artifacts from the resulting material. Chemical and mechanical analyses of the latex and of the processed rubber indicate that the enhanced elastic behavior of the rubber relative to the unprocessed latex is due to purification of the polymer component and to an increase in the strength and number of interchain interactions that are induced by organic compounds present in I. alba. These ancient peoples' control over the properties of latex and processed rubber gave rise to the Mesoamerican ball game, a central ritual element in all ancient Mesoamerican societies.

  7. Twins in Ancient Greece: a synopsis.

    Malamitsi-Puchner, Ariadne

    2016-01-01

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

    Araújo, Adauto; Reinhard, Karl; Ferreira, Luiz Fernando

    2015-01-01

    Parasite finds in ancient material launched a new field of science: palaeoparasitology. Ever since the pioneering studies, parasites were identified in archaeological and palaeontological remains, some preserved for millions of years by fossilization. However, the palaeoparasitological record consists mainly of parasites found specifically in human archaeological material, preserved in ancient occupation sites, from prehistory until closer to 2015. The results include some helminth intestinal parasites still commonly found in 2015, such as Ascaris lumbricoides, Trichuris trichiura and hookworms, besides others such as Amoebidae and Giardia intestinalis, as well as viruses, bacteria, fungi and arthropods. These parasites as a whole provide important data on health, diet, climate and living conditions among ancient populations. This chapter describes the principal findings and their importance for knowledge on the origin and dispersal of infectious diseases. Copyright © 2015 Elsevier Ltd. All rights reserved.

  9. Ancient Greek psychotherapy for contemporary nurses.

    2002-08-01

    Ancient Greek physicians as well as philosophers were fully cognizant of a human being's psychological function and used their particular art to influence individual or social behavior in accordance with their pursuit. This art or technique favorably compares with several of the methods currently called supportive psychotherapy. This psychotherapy was the first form of care for people with mental health problems. Nurses who base their practice on ancient Greek psychotherapy see the patient as a whole, a person who creates meaning in life. Applying the philosophical principles of ancient Greeks helps nurses understand the behavior of people with mental health problems and recognize and facilitate adaptive satisfaction of these psychological needs. In addition, psychiatric nurses are able to help distressed individuals understand their fears and anxieties, so they are freed from the causes of their symptoms that led them to seek therapy in the first place. Consequently, this understanding can make psychiatric nurses' work a living experience and add meaning to their work.

    Analyzing the conditions in which past individuals lived is key to understanding the environments and cultural transitions to which humans had to adapt. Here, we suggest a methodology to probe into past environments, using reconstructed premortem DNA methylation maps of ancient individuals. We review a large body of research showing that differential DNA methylation is associated with changes in various external and internal factors, and propose that loci whose DNA methylation level is environmentally responsive could serve as markers to infer about ancient daily life, diseases, nutrition, exposure to toxins, and more. We demonstrate this approach by showing that hunger-related DNA methylation changes are found in ancient hunter-gatherers. The strategy we present here opens a window to reconstruct previously inaccessible aspects of the lives of past individuals. © The Author 2017.

  12. A study on the migration policy in ancient China.

    Science.gov (United States)

    1995-01-01

    During the Chinese dynasties of Sui and Tang, neighboring minority groups were forced to migrate to less settled areas of China. During the Song dynasty (960-1279) the Han government lost control of neighboring ethnic groups. Ethnically dominated states on their own expanded to the hinterlands, formed the national governments of Yuan and Qing, and established the local power of Liao and Jin in Han-dominated areas. During the Han dynasty the movement of minorities fulfilled the purpose of helping cultivate undeveloped land. The Han governments of feudal China held compulsory migration policies and policies encouraging minorities to move to less inhabited places. Han governments prior to the Tang and Song dynasties held policies favorable to minority settlements. During the Tang dynasty land was given to minority settlers. During the Song dynasty the Han government held a policy which prohibited taxation and harassment of new minority settlers. Minorities gained improved living conditions and the government achieved pacification. Resettlement of minorities either from forced or voluntary migration facilitated communication with the Han and promoted the exchange of culture, but also intensified ethnic conflict. The reason for the ethnic conflict was a question of control. Ethnic governments encouraged in-migration and adopted policies of compulsory and voluntary migration. Ethnic minorities in the north and west practiced mainly compulsory migration. Ethnic conflict in the Qin and Han dynasties occurred between the Han and the Huns. During the Eastern Jin and Northern dynasties minority governments captured Han and other ethnic groups. The rule of minority government was strengthened by voluntary migration. The frequent power shifts in ancient China contributed to the blending of Chinese nationalities.

    1997-01-01

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

    Chinese traditional medicine took its root in Taiwan together with the culture of Central Plains since our ancestors traveled to Taiwan during the turn of the Ming-Qing dynasties. For 400 years, the profession of Chinese medicine continues to develop through the transmission from fathers to sons, from tutors to disciples. During our contacts with Chinese medicinal businessmen, we found that this routinely closed and time-honored profession retained the archaic pronunciation of materia medica from Central Plains in the Han dynasty. This is a living database for studying ancient Chinese language.

    fundamental quantity being given by half the difference between solar distances to vertical at winter and summer solstices, with value about 23.5°. Day and year periods greatly differing by about 2 ½ orders of magnitude, 1 day against 365 days, helps students to correctly visualize and interpret the experimental measurements. Since the gnomon serves to observe at night the moon shadow too, students can also determine the inclination of the lunar orbital plane, as about 5 degrees away from the ecliptic, thus explaining why eclipses are infrequent. Independently, earth taking longer between spring and fall equinoxes than from fall to spring (the solar anomaly), as again verified by the students, was explained in ancient Greek science, which posited orbits universally as circles or their combination, by introducing the eccentric circle, with earth placed some distance away from the orbital centre when considering the relative motion of the sun, which would be closer to the earth in winter. In a sense, this can be seen as hint and approximation of the elliptic orbit proposed by Kepler many centuries later. EPSC Abstracts Vol. 10, EPSC2015-40, 2015 European Planetary Science Congress 2015 c Author(s) 2015 EPSC European Planetary Science Congress Secondly, by observing lunar phases and eclipses from the ground, students could also determine, following Aristarchus of Samos in the 3rd century BC, 4 length ratios involving moon and sun distances to earth, and radii of all three, moon, sun, and earth. The angular width of the moon could be first determined with simplest optical devices as about half a degree; this yields the ratio between moon diameter 2RM and distance DM to earth. Next, eclipses of sun prove its angular width, and thus ratio 2RS/DS, similar to the lunar one, though the relatively high lunar orbital eccentricity, 0.055, does result in not quite a full eclipse if at lunar apogee. Further, at a half-moon phase, when the angle sun-moon-earth is a right one, the angle

  19. A Swarm of Ancient Stars

    Science.gov (United States)

    2010-12-01

    We know of about 150 of the rich collections of old stars called globular clusters that orbit our galaxy, the Milky Way. This sharp new image of Messier 107, captured by the Wide Field Imager on the 2.2-metre telescope at ESO's La Silla Observatory in Chile, displays the structure of one such globular cluster in exquisite detail. Studying these stellar swarms has revealed much about the history of our galaxy and how stars evolve. The globular cluster Messier 107, also known as NGC 6171, is a compact and ancient family of stars that lies about 21 000 light-years away. Messier 107 is a bustling metropolis: thousands of stars in globular clusters like this one are concentrated into a space that is only about twenty times the distance between our Sun and its nearest stellar neighbour, Alpha Centauri, across. A significant number of these stars have already evolved into red giants, one of the last stages of a star's life, and have a yellowish colour in this image. Globular clusters are among the oldest objects in the Universe. And since the stars within a globular cluster formed from the same cloud of interstellar matter at roughly the same time - typically over 10 billion years ago - they are all low-mass stars, as lightweights burn their hydrogen fuel supply much more slowly than stellar behemoths. Globular clusters formed during the earliest stages in the formation of their host galaxies and therefore studying these objects can give significant insights into how galaxies, and their component stars, evolve. Messier 107 has undergone intensive observations, being one of the 160 stellar fields that was selected for the Pre-FLAMES Survey - a preliminary survey conducted between 1999 and 2002 using the 2.2-metre telescope at ESO's La Silla Observatory in Chile, to find suitable stars for follow-up observations with the VLT's spectroscopic instrument FLAMES [1]. Using FLAMES, it is possible to observe up to 130 targets at the same time, making it particularly well suited

  2. Truth Obviousness in Ancient Greek Philosophy

    Directory of Open Access Journals (Sweden)

    Halyna I. Budz

    2013-01-01

    Full Text Available The article examines the features of the axiomatic approach to the truth understanding in ancient Greek philosophy. Truth in the works by ancient philosophers has axiomatic essence, basing on divine origin of truth. As the truth has a divine origin, it is in reality. The reality, created by Gods is the solemn reality. Therefore, understanding of reality by man is the display of divine reality, which is true and clever. In of the context of ancient Greek philosophy, to know truth is to know something, existing in reality, in other words, something, truly existing, eternal reality. Consequently, to know truth is it to know the substantial reality base. That’s why the justification of the reality origin is the axiomatic doctrine of truth at the same time, because only fundamental principle “truly” exists and is the truth itself. The idea of fundamental principle in ancient Greek philosophy is the axiom, universal principle, which is the base of reality as a substance from ontological perspective and is realized as the truth from gnosiological perspective. Fundamental principle, as Greeks understand it, coincides with the truth, in other words, reality and thinking are identical. The idea of reality source is the universal criterion of world perception at the same time, in other words, it is the truth, which is perceived axiomatically.

  3. Discovering the Ancient Maya from Space

    Sever, T. L.

    2008-01-01

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

  7. Ancient DNA analysis of dental calculus.

    Weyrich, Laura S; Dobney, Keith; Cooper, Alan

    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.

  9. 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.

    We analyzed scriptural and archeologic sources of information concerning gynaecology and obstetrics as practiced in ancient Egypt. Knowledge of anatomy was rudimentary but precocious diagnosis of pregnancy was practiced. An obstetrical chair had been used since the VIth dynasty. The Egyptians were the first to describe prolapsus of the genital organs. The pessary was a known treatment. Spermicidal mixtures were used for contraception.

    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.

    Proton induced X-ray emission (PIXE) technique is an effective method for the chemical composition analysis of ancient glass samples without destruction. Chemical composition of the ancient glass samples dated from the Warring States Period (770-476 B.C.) to the Six Dynasties Period (220-589 A.D.), which were unearthed in Sichuan area, was quantitatively determined by the PIXE technique. The results show that the glass Bi (disc) and the glass eye beads of the Warring States Period all belong to the PbO-BaO-SiO 2 system. According to the composition and shape, we infer that these glass Bi and eye beads were made in China. Whereas, the chemical compositions of the glass ear pendants and beads of the Six Dynasties Period are varied, including K 2 O-CaO-SiO 2 , K 2 O-SiO 2 and other glass systems, Based on the obtained results and those from literatures, some questions related to the technical propagation of the ancient Chinese glass are discussed.

    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

    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

  19. Ancient and Medieval Cosmology in Armenian Highland

    2016-12-01

    Humankind has always sought to recognize the nature of various sky related phenomena and tried to give them explanations. It is especially vivid in ancient cultures, many of which are related to the Middle East. The purpose of this study is to identify ancient Armenian's pantheistic and cosmological perceptions, world view, notions and beliefs. By this study we answer the question "How did the Universe work in Ancient Armenian Highland?" The paper focuses on the structure of the Universe and many phenomena of nature that have always had major influence on ancient Armenians thinking. Here we weave together astronomy, anthropology and mythology of Armenia, and scientific thinking revealed in local astronomy traditions. The initial review of the study covers Moses of Khoren, Yeznik of Koghb, Anania Shirakatsi and other 5th-7th centuries historians' and scientists' records about the Universe related superstitious beliefs and cosmological understanding. By discussing and comparing Universe structure in various regional traditions, myths, folk songs and phraseological units we very often came across "seven worlds", "seven earths" and "seven layers" concepts. We draw parallels between scientific and mythological Earth and Heaven and thus find similar number of layers on both of the ancient and modern thinking. In the article we also give some details about the tripartite structure of the Universe and how these parts are connected with axis. This axis is either a column or a Cosmic Tree (Kenatz Tsar). In Armenian culture the preliminary meanings of the Kenatz Tsar are more vivid in folk songs (Jan gyulums), plays, epic, and so on, which was subsequently mixed with religious and spiritual views. We conclude that the perception of the Universe structure and celestial objects had a significant impact on culture and worldview of the people of the Armenian Highland; particularly it was one of the bases of the regional cultural diversity.

  20. Estimate of the Chinese astronomy development through the descriptions of nova observations

    Science.gov (United States)

    Nickiforov, Mihael G.

    More than a hundred descriptions of guest stars observations made by Chinese, Korean and Japanese astronomers from 6th till 17th centuries are examined in this work. The comparison of the distribution of star outbursts on galactic latitudes from the Chinese sources with the modern data casts doubt on the reliability of the ancient observations. The text analysis shows that the technique of the descriptions of the places of outbursts of new stars does not change from the first ancient observations till the 16th century. This is a sign of a lack of precise instrumental measurements until the arrival of the Jesuits, in 16th century, and of a lack of Chinese star catalog in the medieval China.

    Full Text Available This article aimed to provide documentation of information relating to local intelligence from the older generations, specifically the local intelligence of the Chinese community on gemstones.To better understand this issue, an informal interview had been conducted on an informant from the Chinese community who has vast experiences dealing with gemstone crafting. Literature reviews were also carried out to further understand the issue under discussion. It can be assumed that religion is the main factor influencing the use of gemstones among ancient Chinese. Although other aspects such as luck, prestige, and healing may also exist, the reasons would be solely based on the teachings of Buddhism. In summary, every God’s creations possess benefits and it is up to human to utilise them in either beneficial or adverse ways

    Based on ancient literature of acupuncture in Canon of Chinese Medicine (4th edition), the articles regarding acupuncture for urinary incontinence were retrieved and collected to establish a database. By Weka data mining software, the multi-level association rules analysis method was applied to analyze the acupoints selection characteristics and rules of ancient acupuncture for treatment of urinary incontinence. Totally 356 articles of acupuncture for urinary incontinence were collected, involving 41 acupoints with a total frequency of 364. As a result, (1) the acupoints in the yin-meridian of hand and foot were highly valued, as the frequency of acupoints in yin-meridians was 2.6 times than that in yang-meridians, and the frequency of acupoints selected was the most in the liver meridian of foot-jueyin; (2) the acupoints in bladder meridian of foot-taiyang were also highly valued, and among three yang-meridians of foot, the frequency of acupoints in the bladder meridian of foot-taiyang was 54, accounting for 65.85% (54/82); (3) more acupoints selected were located in the lower limbs and abdomen; (4) specific acupoints in above meridians were mostly selected, presenting 73.2% (30/41) to the ratio of number and 79.4% (289/364) to the frequency, respectively; (5) Zhongji (CV 3), the front-mu point of bladder meridian, was seldom selected in the ancient acupuncture literature, which was different from modern literature reports. The results show that urinary incontinence belongs to external genitalia diseases, which should be treated from yin, indicating more yin-meridians be used and special acupoints be focused on. It is essential to focus inheritance and innovation in TCM clinical treatment, and applying data mining technology to ancient literature of acupuncture could provide classic theory basis for TCM clinical treatment.

    Coal is an organic matter and is a product of sedimentary environments. The most favourable areas for coal-forming flora are the shallow-swampy environments which are developed in various parts of sedimentary basins occurring along sea-shores, deltas and lakes. Sedimentary basins contain deposits that may be several hundred kilometers in length and width and a few thousand meters in thickness. Different environments of deposition and associated sediments may develop in a basin through all the periods of geological history, and the deposits may grade into one another both laterally and vertically. Since the environments of coal deposition are known, it is easy to deduce how and where to search for coal occurrences in an ancient sedimentary environment. Large coal deposits of economic interest occur in lacustrine, deltaic and fluvial environments, and lagoons and barrier islands. The most noticeable and characteristic features of the ancient depositional environments in which coal deposits occur are described. 60 refs., 8 figs.

In contrast, there was also a specific encouragement of spectacles and performance or general entertainment during the Imperial Era. In order to cater for the diverse shows, sophisticated buildings were constructed in Rome, and reproduced in all the built-up areas throughout the Empire. In fact, besides the important circus network, the most emblematic of these being Maximo's Circus, amphitheatres, arenas and spa resorts were constructed, in addition to the Dominitian Stadium. The author studies the different types of «sporting» installations in Ancient Rome, considering the entertainments which took place in them: chariot races, gladiatorial combat, the hunting of wild beasts, naval combats, the stadium sports and, of course, the Roman passion for spas and hot baths.

    It is now universally accepted that utilization of lead for domestic purposes and water distribution presents a major health hazard. The ancient Roman world was unaware of these risks. How far the gigantic network of lead pipes used in ancient Rome compromised public health in the city is unknown. Lead isotopes in sediments from the harbor of Imperial Rome register the presence of a strong anthropogenic component during the beginning of the Common Era and the Early Middle Ages. They demonstrate that the lead pipes of the water distribution system increased Pb contents in drinking water of the capital city by up to two orders of magnitude over the natural background. The Pb isotope record shows that the discontinuities in the pollution of the Tiber by lead are intimately entwined with the major issues affecting Late Antique Rome and its water distribution system.

    Computerized gas chromatography-mass spectrometry (GC-MS) is now an essential tool in the analysis of the complex mixtures of lipids (geolipids) encountered in aquatic sediments, both 'recent' (less than 1 million years old) and ancient. The application of MS, and particularly GC-MS, has been instrumental in the rapid development of organic geochemistry and environmental organic chemistry in recent years. The techniques used have resulted in the identification of numerous compounds of a variety of types in sediments. Most attention has been concentrated on molecules of limited size, mainly below 500 molecular mass, and of limited functionality, for examples, hydrocarbons, fatty acids and alcohols. Examples from recent studies (at Bristol) of contemporary, 'recent' and ancient sediments are presented and discussed.

    The presentation of the cult of phallus in ancient Greece and the artistic appearance of the phenomenon on vase figures and statues, as indicative of the significant role of the male genitalia in all fertility ceremonies. The examination of a great number of penile representations from the ancient Greek pottery and sculpture and the review of the ancient theater plays (satiric dramas and comedies ). Phallus in artistic representation is connected either with gods of fertility, such as the goat-footed and horned Pan or the ugly dwarf Priapus or the semi-animal nailed figures Satyrs, devotees of the god Dionysus accompanying him in all ritual orgiastic celebrations. Phallus also symbolizes good luck, health and sexuality: people bear or wear artificial phalli exactly like the actors as part of their costume or carry huge penises during the festive ritual processions. On the contrary, the Olympic gods or the ordinary mortals are not imaged ithyphallic; the ideal type of male beauty epitomized in classical sculpture, normally depicts genitals of average or less than average size. It is noteworthy that many of these images belong to athletes during or immediately after hard exercise with the penis shrunk. The normal size genitalia may have been simply a convention to distinguish normal people from the gods of sexuality and fertility, protectors of the reproductive process of Nature. The representation of the over-sized and erected genitalia on vase figures or statues of ancient Greek art is related to fertility gods such as Priapus, Pan and Satyrs and there is strong evidence that imagination and legend were replacing the scientific achievements in the field of erectile function for many centuries.

  13. Cosmologies of the ancient Mediterranean world

    Directory of Open Access Journals (Sweden)

    John T. Fitzgerald

    2013-07-01

    Full Text Available Cosmology is concerned with the order of the universe and seeks to provide an account, not only of that order, but also of the mind or reason behind it. In antiquity, the cosmos was usually understood religiously, such that the cosmologies of the ancient Mediterranean world were either religious in nature or constituted a reaction to a religiously conceived understanding of the structures of the universe. The oldest form in which ancient cosmologies occur is myth, which, owing to its elasticity as a form, enabled them to be appropriated, adapted and used by different groups. In addition, different cosmologies co-existed within the same ancient culture, each having an authoritative status. This article provides an introductory overview of these cosmological myths and argues that a comparative approach is the most fruitful way to study them. Emphasis is given to certain prominent cosmological topics, including theogony (the genesis of the divine or the relationship of the divine to the cosmos, cosmogony (the genesis of the cosmos, and anthropogony (the origin of humans within the cosmos. Although these myths vary greatly in terms of content and how they envision the origin of the cosmos, many of them depict death as part of the structure of the universe.

    Homosexuality and pedophilia in ancient Greece greatly concerned many researchers who were mainly interested in highlighting the social aspect of this phenomenon in ancient Greek society. An important source on the subject was the paintings of a man and his lover in attic black and red figured pottery, up to the end of the 5th century BC. Another main source was the information that derived from the texts of ancient Greek literature, especially poetry. Homosexuality was not only referring to relationships between males, but it was also manifested in lesbian love. It is believed that in the Homeric world homosexuality was not favored. In Greek society of the archaic period, the restriction of women at home, the satisfaction of sexual needs with courtesans, the marriage for the purpose of maintaining and managing the property, put women aside, marginalizing them in terms of social life, impeding the cultivation of emotional relationships between sexes. At the same time, in the society of those times, the aristocratic ideal, the constant communication of men during military training and the war, the male nudity in sports and the promotion of beauty and bravery in athletic contests, as well as the gatherings and the entertainment of men at the symposia, created a suitable substrate in which male homosexuality could develop. In this context, pedophile relationships were developed mainly during the archaic period, as recorded on vase paintings, where a mature man developed a special relationship with a teenager of the same social class. The mature man had the role of mentor for the juvenile, he would look after him and cover his living expenses and education cost. In this relationship, exhibiting predominantly the social dimension of an initiation process and introduction to adult life, the erotic homosexual intercourse could find a place to flourish. The above-mentioned relationship could not last forever, given that this would later transform into an emotional

    Archaeological discoveries from the Chinese Bronze Age have demonstrated a dominant concern with achieving cardinal orientation that persisted throughout the Xià, Shāng, and Zhōdu dynasties (ca. 2000 -- 300 BCE). It has long been understood that cardinality is an index of the paradigmatic roles of ``the center'' and ``the four quarters'', both core organizing principles of early Chinese cosmological thinking. Here, however, I focus on a very early practical technique used to identify the location of the pole in the absence of a pole star. This method takes advantage of the unique orientation of the Great Square of Pegasus (known as Ding} in early China) and offers insight into a fundamental mindset that figured importantly in the formation of early Chinese Civilization.

    To examine the practice of urology in ancient Egypt using various sources, including the Edwin Smith and Ebers Papyri. The sources of knowledge of ancient Egyptian medicine include medical papyri, paleopathology, art, and hieroglyphic carvings. A brief overview of the medical system in ancient Egypt was completed, in addition to an examination of the training and specialization of the physician in the ancient world. Urologic diseases treated in ancient Egypt and some of the first documented urologic surgeries are presented. Finally, we studied the role of the physician-priest and the intertwined use of religion and magic in ancient Egyptian medicine. The same medical conditions urologists treat in the office today were methodically documented thousands of years ago. Medical papyri show evidence that the ancient Egyptians practiced medicine using a scientific method based on the clinical observation of disease. This has been exemplified by the Edwin Smith Surgical Papyrus, a collection of surgical cases that gives a diagnosis, treatment, and prognosis for each ailment, and the discovery of medical specialization in ancient Egypt, giving us perhaps the world's first urologists. Intertwined with the scientific method was also the rich mysticism and religion of ancient Egypt, which were integral components of the healing process. We present an overview of the practice of urology in ancient Egypt, in terms of both pharmacologic and surgical intervention, as well as with a look into the religion of medicine practiced at that time.

    China is one of the most dynamic regions in the world in terms of economic growth and development. Such development has inevitably influenced the structure and habits of Chinese society. Whilst the economic condition of the middle class and high-income segment has steadily improved, cultural changes are also under way: ancient Chinese traditions now include major elements from other cultures, most notably the West. The above scenario is the background to this paper. A structured research-administered survey was developed to investigate the changes in the Chinese consumer food culture: 500 urban participants were randomly selected from six reference cities, covering geographically almost the whole country. This study aims not only to analyze the propensity of consumers to include food products from other countries in their ancient Chinese culinary culture, but also represents an initial attempt to perform a market segmentation of Chinese consumers according to their degree of cultural openness towards non-Chinese food, taking into account socio-demographic, cognitive and psychographic variables.

    With the inspiration of an ancient Chinese poison test approach, we report a rapid hydrogen sulfide detection strategy in specific areas of live cells using silver needles with good spatial resolution of 2 × 2 μm(2). Besides the accurate-localization ability, this reflection-based strategy also has attractive merits of convenience and robust response when free pretreatment and short detection time are concerned. The success of endogenous H2S level evaluation in cellular cytoplasm and nuclear of human A549 cells promises the application potential of our strategy in scientific research and medical diagnosis.

    Most genetic studies of Holocene fauna have been performed with ancient samples from dry and cold regions, in which preservation of fossils is facilitated and molecular damage is reduced. Ancient DNA work from tropical regions has been precluded owing to factors that limit DNA preservation (e.g. temperature, hydrolytic damage). We analysed ancient DNA from rodent jawbones identified as Ototylomys phyllotis, found in Holocene and Late Pleistocene stratigraphic layers from Loltún, a humid tropi...

    2011-01-01

    This article addresses the issue of capturing the medical entity called 'curved legs' in a terminologically exact way. In so doing, it refers to the long-lasting process of differentiation of exact nuances of meaning in Ancient Greek and Latin. In the chronological perusal of ancient Greek literature, it becomes evident that the various adjectives employed are often vague when looking at non-medical literature. By contrast, in the Hippocratic corpus these terms are for the first time annotated with explanations intended to lead to a more precise understanding of the described deformity. Further attempts of differentiation can be found in the writings of Galen, who not only distinguishes between outward and inward curvatures, but also between deformities of the thigh and lower leg as well as between pathological and natural curvatures. Latin literature also provides a series of adjectives that were initially often used in the meaning of 'curved' but it was not until Celsus that these were differentiated with respect to the type and direction of the curvature. When comparing Greek and Latin adjectives, it turns out that though the Latin term blaesus can be traced back etymologically to the Greek word beta lambda alpha iota sigma ó zeta, the meaning of beta lambda alpha iota sigma ó zeta does not fully correspond to that of the Latin word. It is not before the later common transliteration of Greek words that this adjective took on the meaning of beta lambda alpha iota sigma ó zeta; however, this was finally lost again. In summary, the article concludes that exact word meanings in ancient literature are often unclear and precise ascriptions of meanings are inconsistent. In the case of "curved legs," this has led to misunderstandings regarding the respective types and directions of the curvature.

    Safety analysis of an ancient iron structure, Danggan, constructed over than a thousand years ago was performed. The structure is consisted of 24 iron cylinders of which the total height is about 15.4 m. The analysis was done by the ultrasonic test to measure thickness of each cylinder, the radiographic test to investigate the inside of cylinders, the measurement of inclination of the structure and the structural analysis to estimate the stress level applied by the wind. Results showed that Danggan structure was on state being well safe at present, but it could be dangerous when the inclination of the structure becomes severely progressive.

    Colchicine is a treatment for gout that has been used for more than a millennium. It is the treatment of choice for familial Mediterranean fever and its associated complication, amyloidosis. The 2009 U.S. Food and Drug Administration approval of colchicine as a new drug had research consequences. Recent investigations with large cohorts of patients with gout who have been taking colchicine for years have demonstrated novel applications within oncology, immunology, cardiology and dermatology. Some emerging dermatological uses include the treatment of epidermolysis bullosa acquisita, leucocytoclastic vasculitis, aphthous stomatitis and others. In this work we relate the history and the new horizon of this ancient medicine. © 2017 British Association of Dermatologists.

    Attitudes toward suicide have not always been the same as they are today, and understanding the ideas of other cultures and times could enable us to reexamine contemporary conceptions of self-killing. Greek and Roman personal testimonies were examined to investigate the thesis that ancients did not see suicide as caused by psychic or emotional forces. Indeed, though the documents of antiquity give us a closer look into personal motives, they demonstrate that even would-be self-killers themselves wished to regard suicide as a rational act of volition.

    To further explore the clinical effect of massage therapy on navel,the related ancient literatures were arranged and analyzed,and several methods in ancient clinical were introduced, including stroking navel, rubbing navel, pushing navel, tapping navel and puffing navel. In addition, the theoretical basis of massage therapy on navel were discussed. The results revealed ancient literatures offered abundant theoretical basis to modern clinical practice, and there were evidences of treating gastroenteric and gynecological diseases with this therapy. Comprehensively, through the study of ancient literatures and modern research, therapy of massage on navel is believed to be promising and will gain popularity in the future.

    Objective: Chinese Mongolian osteopathy has been passed down from ancient times and includes unique practices and favorable efficacy. In this study, we investigate the macroscopic biological characteristics of individualized Chinese Mongolian osteopathy, in order to provide new principle and methods for the treatment of bone fracture. Method: With a view to provide a vital link between nature and humans, the four stages of Chinese Mongolian osteopathy focus on the unity of the mind and body, the limbs and body organs, the body and its functions, and humans and nature. Results: We discuss the merits of individualized osteopathy in terms of the underlying concepts, and evaluate the approaches and principles of traditional medicine, as well as biomechanics. Conclusions: Individualized Mongolian osteopathy targets macroscopic biological components including dynamic reduction, natural fixation, and functional healing. Chinese Mongolian osteopathy is a natural, ecological and non-invasive osteopathy that values the link between nature and humans, including the unity of mind and body. The biological components not only serve as a foundation for Chinese Mongolian osteopathy but are also important for the future development of modern osteopathy, focusing on individualization, actualization and integration.

    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).

  15. [Heat and Fever in ancient Greek physiology].

    2009-12-01

    This paper aims at clarifying the relationship of physiological heat and pathological heat(fever) using the theoretical scheme of Georges Canguilhem as is argued in his famous book The Normal and the Pathologic. Ancient authors had presented various views on the innate heat and pathological heat. Some argued that there is only pathological heat while others, like Galen, distinguished two different kinds of heat. Galen was the first medial author who had the clear notion of the relationship between the normal heat and the pathological heat. He conceptualized their difference as the heat conforming to nature (kata phusin) and the heat against nature (para phusin). However, the Peripatetic authors, such as ps-Alexander Aphrodisias, who laid more emphasis on physiology tended to regard pathology in continuation with physiology as Claude Bernard attempted to do it. Therefore, Canguilhem's theoretical scheme turns out to be very useful in analysing the relationship of normal heat and pathological heat as is manifested in ancient Greek physiology.

    Full Text Available In this historical review, the opinions of Ancient Greece philosophers, astronomers, and poets such as Thales Milesian, Pythagoras, Plato, Eudoxus, Aristotle, Archimedes, Cicero, Diogenes Laertius, Iamblichus, Plutarch, Homer, and Aratus about the planet position calculations and about the possibility of predictions of natural phenomena are analyzed. The planet positions were predicted before Eudoxus (probably before Philolaus by a spindle of Ananke and after Eudoxus by Antikythera mechanism. Following Pythagoras and Plato, it is established that the regular seismoacoustic observations were performed. In the Ancient World in the Mediterranean area, there was an extensive network of acoustic stations (~10 pcs, which were located in close proximity to the geologic faults. Also, it is shown that the ship that was carrying Antikythera mechanism (A-Ship was built in 244 BC in Syracuse with direct participation of Archimedes and Archias from Corinthian. Later, the A-Ship was a part of the Roman Republic safety system. The grain volumes, which were delivered to Rome city by large grain vessels, and the population of Rome city in the period 74–71 BC were estimated. Planetary calculator might be used for the chronology of the historical events as a backward prediction in addition to present Radiocarbon dating and Dendrochronology methods.

  17. Ancient eclipses and the Earth's rotation

    Science.gov (United States)

    Morrison, L. V.; Stephenson, F. R.

    Observations of ancient and medieval eclipses are compared with predictions to measure changes in the Earth's rotation over the past 2500 years. The observations are treated in two broad categories: untimed and timed. An untimed observation must have the place and date, but not the time, as the special geometry of the eclipse path essentially supplies this. A timed observation requires the time of day of the eclipse as well as the date and place. In the period 700BC to AD1600 we have found 106 reliable untimed and 343 timed observations of solar and lunar eclipses recorded by the ancient/medieval civilizations of Babylon, China, the Arab Dominions and Europe. Analyses of these two independent datasets lead to the conclusion that the rate of rotation is decreasing, such that the length of the day (lod) is increasing on the average by 1.8 milliseconds per century (ms/cy). This is consistent to within the accuracy of measurement with the resultant sum of a tidal increase of 2.3 ms/cy and a decrease of 0.5 ms/cy due to post-glacial uplift following the end of the last ice-age. Besides these secular changes, there is clear evidence of fluctuations in the lod of several ms on a timescale of centuries.

    Ancient DNA recovered from 57 individuals excavated by Hiram Bingham at the rural communities of Paucarcancha, Patallacta, and Huata near the famed Inca royal estate and ritual site of Machu Picchu was analyzed by polymerase chain reaction, and the results were compared with ancient and modern DNA from various Central Andean areas to test their hypothesized indigenous highland origins. The control and coding regions of the mitochondrial DNA (mtDNA) of 35 individuals in this group were sequenced, and the haplogroups of each individual were determined. The frequency data for the haplogroups of these samples show clear proximity to those of modern Quechua and Aymara populations in the Peruvian and Bolivian highlands, and contrast with those of pre-Hispanic individuals of the north coast of Peru that we defined previously. Our study suggests a strong genetic affinity between sampled late pre-Hispanic individuals and modern Andean highlanders. A previous analysis of the Machu Picchu osteological collection suggests that the residents there were a mixed group of natives from various coastal and highland regions relocated by the Inca state for varied purposes. Overall, our study indicates that the sampled individuals from Paucarcancha and Patallacta were indigenous highlanders who provided supportive roles for nearby Machu Picchu. 2006 Wiley-Liss, Inc.

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

    Chemical composition analysis is one of the most important research aspects to provide scientific proof for the technical origin and development of Chinese ancient glass. Proton induced X-ray emission (PIXE) technique is a kind of multi-element quantitative analysis method with high sensitivity and without destruction of samples. Chemical composition of the Western Han dynasty glass garment flakes, which were excavated from Yangzhou city, was analyzed by PIXE, quantitatively. It was found that these glass flakes were attributed to PbO-BaO-SiO 2 glass originated in China. These flakes all consist of a glass core and a corroded outer layer with different thickness. There are relatively higher PbO, P 2 O 5 and CaO, while much lower BaO and SiO 2 in the corroded layers than in the glass cores. The experimental results were discussed

    Full Text Available This study proposes a novel square-circle structure fractal multibroadband planar antenna, similar to an ancient Chinese coin-like structure, for second generation (2G, third generation (3G, fourth generation (4G, WLAN, and navigation wireless applications. The device is based on the principles and structural features of conventional monopole antenna elements, combined with the advantages of microstrip antennas and fractal geometry. A fractal method was presented for circular nested square slotted structures, similar to an ancient Chinese copper coin. The proposed antenna adapted five iterations on a fractal structure radiator, which covers more than ten mobile applications in three broad frequency bands with a bandwidth of 70% (1.43–2.97 GHz for DCS1800, TD-SCDMA, WCDMA, CDMA2000, LTE33-41, Bluetooth, GPS (Global Positioning System, BDS (BeiDou Navigation Satellite System, GLONSS (Global Navigation Satellite System, GALILEO (Galileo Satellite Navigation System, and WLAN frequency bands, 16.32% (3.32–3.91 GHz for LTE42, LTE43, and WiMAX frequency bands, and 10.92% (4.85–5.41 GHz for WLAN frequency band. The proposed antenna was fabricated on a 1.6 mm thick G10/FR4 substrate with a dielectric constant of 4.4 and a size of 88.5 × 60 mm2. The measurement results reveal that the omnidirectional radiation patterns achieve a gain of 1.16–3.75 dBi and an efficiency of 40–72%. The good agreement between the measurement results and simulation validates the proposed design approach and satisfies the requirements for various wireless applications.

    2013-01-01

    Full Text Available Myocardial ischemia-reperfusion (MIR injury is a major contributor to the morbidity and mortality associated with coronary artery disease, which accounts for approximately 450,000 deaths a year in the United States alone. Chinese herbal medicine, especially combined herbal formulations, has been widely used in traditional Chinese medicine for the treatment of myocardial infarction for hundreds of years. While the efficacy of Chinese herbal medicine is well documented, the underlying molecular mechanisms remain elusive. In this review, we highlight recent studies which are focused on elucidating the cellular and molecular mechanisms using extracted compounds, single herbs, or herbal formulations in experimental settings. These studies represent recent efforts to bridge the gap between the enigma of ancient Chinese herbal medicine and the concepts of modern cell and molecular biology in the treatment of myocardial infarction.

    The objective of the work reported is to study experimentally on the removal of corrosion layer from the ancient coins using laser beam as the conservation tool. With the use of Q-switched Nd:YAG laser radiation at 1064 nm, dry laser cleaning, steam laser cleaning and chemical-assisted laser cleaning were used to find out a more suitable and efficient laser treatment for corrosion removal. Cleaning tests were performed on ancient Chinese coins. Experimental results shows that the dry laser cleaning was not successful at removing all types of corrosion crust. It was possible to remove the outer thicker layer of the corrosion products (typically known as patina), but failed on the thinner layer of cuprite. The steam laser cleaning could decrease the initial removal threshold and improve the removal efficiency especially for the oxidation with powdery structure. As for chemical-assisted laser treatment, the cleaning results demonstrate that the combination of laser and chemical reagent could provide a considerable improvement in corrosion removal compared with the conventional laser treatments. Most of the corrosion contaminant was stripped, even the cuprite layer. Moreover, no secondary pollution was formed on the cleaned surface. X-ray fluorescence was applied to determine the variation of composition of surface layer and bulk metal before and after the coins cleaned. It shows that all of the three laser treatments were efficient to reduce the chlorine concentration on the surface of the coins more than 75%.

    Benoit, William L.

    The notion that rhetoric (and to a lesser extent, argument) is epistemic is an increasingly popular one today, although it can be traced to ancient Greece. The notion holds that rhetoric, or the art of persuasion, creates and shapes knowledge. Two ancient authors--Aristophanes and Plato--provide evidence that others had notions of rhetoric as…

  17. Mapping The Ancient Maya Landscape From Space

    2002-01-01

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

  18. Information about Macedonian medicine in ancient Greece.

    Giannouli, Vaitsa; Syrmos, Nikolaos

    2011-01-01

    Ancient Greek Macedonians were highly interested in the improvement of their physical and psychological health. At first, they worshiped the mythical god Asclepius and his daughter Hygieia. In at least 24 places in northern Greece, in Halkidiki, Thessaloniki, Kozani, Kavala, Thassos, Serres and other places, archaelogical findings were related to Asclepius. Macedonian kings were also interested in the development of medicine, for the sake of their fellow citizens and their soldiers. Characteristic examples are the close relations of Hippocrates with king Perdikas (5(th) century B.C.) and of Nicomachus (Aristotle's father being a physician) with king Amintas. Alexander the Great had as his personal physician, the famous physician Philippos of Acarnania. An incident between Alexander and Philippos of Acarnania shows the respect of Macedonian kings to their doctors: Alexander became ill after a bath in the frozen river Cydnus (near ancient Tarsus). At this time he received a letter from his general Parmenion for not to trust his physician. Alexander gave this letter to Philippos to read it and while Philippos was reading it and was rather frightened, he saw Alexander drinking the medicine he had given him. We may note that Alexander the Great as a student of Aristotle had a general education about medicine. Archaeological findings revealed two funerary monuments of physicians: a doctor from Thasos, who practiced in Pella as a public physician during the 3rd quarter of the 4(th) century B.C. and a physician named Alexander, who lived in the 1rst half of the 5(th) century A.D. The tomb of a third physician, probably a surgeon, excavated in Pydna, near mount Olympus (3(rd) century BC)also indicates the importance of physicians in Macedonia. Archaeological findings, like surgical knives, from the Hellinistic and Roman periods, found in the city of Veria, also showed the respect of Ancient Greeks to medicine and to their physicians. An example is the skeleton of a young

  19. [Changes of marriage age in ancient China].

    Zhang, D

    1991-04-01

    The changes in age of marriage in ancient China can be classified into 3 periods. Around 680 B.C., the government set the age of marriage at 20 for men and at 15 for women. Even though it was written in the works of the Confucian school that men should marry at 30 and women at 20, it was never really followed. The Wei and Jin dynasties provided the longest periods of war and social instability. Large numbers of population died because of war or famine. Because heavy taxes were collected on each member of family, many families did not report marriage or childbirth. In order to encourage childbirth, the government reduced the age of marriage to 15 for men and 13 for women. Administrative and legislative regulation were introduced to force people to marry early, especially women. Incentives were given to families with more women. These policies was enforced due to the imbalance of the sex ratio and reduction of population size. As female infanticides were prevalent because of differential values placed on male and female children, it was difficult for men to find partners to marry. Shortage of women was also the result of the polygamy of the rich and the aristocracy. The imbalance of the sex ratio forced women to marry early. Nevertheless, women getting married too early were not fertile. Infant or child mortality was high among children of young mothers. From the Song to the Ching dynasties, the age of marriage was set at 16 for men and 14 for women. In the ancient times, the population of China was around 60-70 million before the Ching dynasty. Generally speaking, the population size was small. Early marriage was necessary and feasible. Even though fertility in ancient times was high, mortality has high also. Life expectancy ranged form 22 to 35. People needed to marry early and have children early to replace themselves. On the other hand, large land areas and inefficient production tools required a larger labor force. Large population size also represented

  20. Exploring Ancient Skies An Encyclopedic Survey of Archaeoastronomy

    Kelley, David H

    2005-01-01

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

    Ancientness and maturity are two major qualities of forest ecosystems. They are components of naturalness and are affected by human impact. These qualities and the associated terms are often mixed up and incorrectly used. We have carried out a synthesis in order to propose an adapted French terminology based on international literature. The topics of ancientness and maturity for biodiversity and soil characteristics are explained. This review leads us to submit different potential thresholds for ancientness and maturity. An analysis on ancientness and maturity on forest data for France leads to the conclusion that about 29% of all forests can be considered "ancient woodland", and less than 3% of the even-age forest is older than the harvesting age.

    2011-12-01

    Full Text Available A comparative study of the ancient Chinese and Western artworks over the same period (from approximately 3300 B.C. to 200 B.C shows that the dense and rich decorative patterns on the bronze wares in China represent a strong aesthetic appreciation of patterns/embellishment, while their counterparts in the West demonstrate an aesthetic orientation rooted in science, evident in nude bodies in bronze and marble. It is argued that there was a very obvious essential difference between Chinese and Western aesthetic values, and these divergent aesthetic orientations were present at the origins of the Pre-Qin and ancient Greek arts where they have been absorbed into the foundation of each culture.

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

    2017-01-01

    This book describes the inventions and designs of ancient engineers who are the precursors of the present. The period ranges mainly from 300 B.C. to 1600 A.D. with several exceptions. Many of the oldest inventions are documented by archaeological finds, often very little known, mainly from Pompeii, Herculaneum and Stabiae and reveal a surprising modernity in their conception. Most of the inventions presented in the first four parts of the book were conceived up to the late Roman Empire and may be considered as milestones, each in their respective field. The fifth part concentrates on more recent centuries. The sixth part deals with some building construction techniques. Generally, for each of the presented inventions, three elements of research and reference are provided: written documents (the classics), iconic references (coins, bas-reliefs, etc.) and archaeological findings. The authors did not write this book for engineers only; hence they describe all the devices without assuming wide technical knowledge...

  7. The Ancient Evolutionary History of Polyomaviruses.

    Directory of Open Access Journals (Sweden)

    Christopher B Buck

    2016-04-01

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

    Singh, Satendra; Khetarpal, Abha

    2012-04-01

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

  9. Optical spectroscopy of ancient paper and textiles

    Missori, M.

    2016-01-01

    Ancient paper and textiles represent a striking example of optically inhomogenous materials whose optical responses are strongly governed by scattering effects. In order to recover the absorption coefficient from non-invasive and nondestructive reflectance measurements a specific approach based on Kubelka-Munk two-flux theory must be applied. In this way quantitative chemical information, such as chromophores concentration, can be obtained, as well as quantitative spectra of additional substances such as pigments or dyes. Results on a folio of the Codex on the Flight of Birds by Leonardo da Vinci and a linen cloth dated back to 1653 and called the Shroud of Arquata, a copy of the Shroud of Turin, will be presented.

  10. Were the ancient Romans art forgers?

    Directory of Open Access Journals (Sweden)

    William Casemen

    2016-12-01

    Full Text Available A popularly held tenet in the historical record on art is that the practice of forgery began in ancient Rome, where sculptures made by craftsmen of the day were passed off as classical Greek antiquities. However, revisionist scholars in recent decades have challenged this perspective. One line of criticism denies that forgery was present in Rome, asserting that the evidence for it has been misunderstood. A softer line suggests that while the traditional view overstates the case, there is still reason to accept that the culture of Rome harbored art forgery. This article assesses the competing claims in light of literary references by Roman authors, physical evidence including inscriptions on sculptures, the phenomenon of Corinthian bronze, the nature of Roman copying, social and economic conditions necessary for art forgery to arise, and what art forgery consists of by definition.

    As the durability of cemented matrices is a matter of great importance in numerous domains, notably for the long term reliability of surface storages of radioactive wastes, the objective of this research thesis is to define mechanisms of evolution of cemented matrices when in contact with diluted aqueous solutions. The author notably studied the influence of the lixiviation mode on the evolution of two mortars having different compositions (pH, CO 2 pressure, system containment, and cement mineralogical nature appear to be the main governing parameters), the alteration (dissolution is the prevailing process in the interaction between cemented matrices and a diluted solution such as rain water), and ancient binders (archaeological binders containing mineral phases such as hydrated calcium silicates or hydro-grossulars). The obtained results lead to the definition of alteration mechanisms in modern cements, and highlight factors governing the durability of these materials when submitted to meteoric alteration [fr

    The book is a collection of short stories, small anecdotes in the life of some historical characters. More concretely, it focuses on the oddities and singularities of some well-known historical figures, not only in science, but also in arts, politics and social sciences. … the book shows the fascination for ancient history, the treasures hidden in original sources and the importance of exploring unusual connections.-Javier Martinez, The European Mathematical Society, January 2013… a rambling, illuminating and thoroughly enjoyable bio/autobiographical and historical sketch, setting Pingree's immense erudition in its professional and intellectual context.

  16. Can Digital Computers Support Ancient Mathematical Consciousness?

    Directory of Open Access Journals (Sweden)

    Aaron Sloman

    2018-05-01

    Full Text Available This paper poses, discusses, but does not definitively answer, the following questions: What sorts of reasoning machinery could the ancient mathematicians, and other intelligent animals, be using for spatial reasoning, before the discovery of modern logical mechanisms? “Diagrams in minds” perhaps? How and why did natural selection produce such machinery? Is there a single package of biological abilities for spatial reasoning, or did different sorts of mathematical competence evolve at different times, forming a “layered” system? Do the layers develop in individuals at different stages? Which components are shared with other intelligent species? Does some or all of the machinery exist at or before birth in humans and if not how and when does it develop, and what is the role of experience in its development? How do brains implement such machinery? Could similar machines be implemented as virtual machines on digital computers, and if not what sorts of non-digital “Super Turing” mechanisms could replicate the required functionality, including discovery of impossibility and necessity? How are impossibility and necessity represented in brains? Are chemical mechanisms required? How could such mechanisms be specified in a genome? Are some not specified in the genome but products of interaction between genome and environment? Does Turing’s work on chemical morphogenesis published shortly before he died indicate that he was interested in this problem? Will the answers to these questions vindicate Immanuel Kant’s claims about the nature of mathematical knowledge, including his claim that mathematical truths are non-empirical, synthetic and necessary? Perhaps it’s time for discussions of consciousness to return to the nature of ancient mathematical consciousness, and related aspects of everyday human and non-human intelligence, usually ignored by consciousness theorists.

  17. Ancient water supports today's energy needs

    The water footprint for fossil fuels typically accounts for water utilized in mining and fuel processing, whereas the water footprint of biofuels assesses the agricultural water used by crops through their lifetime. Fossil fuels have an additional water footprint that is not easily accounted for: ancient water that was used by plants millions of years ago, before they were transformed into fossil fuel. How much water is mankind using from the past to sustain current energy needs? We evaluate the link between ancient water virtually embodied in fossil fuels to current global energy demands by determining the water demand required to replace fossil fuels with biomass produced with water from the present. Using equal energy units of wood, bioethanol, and biodiesel to replace coal, natural gas, and crude oil, respectively, the resulting water demand is 7.39 × 1013 m3 y-1, approximately the same as the total annual evaporation from all land masses and transpiration from all terrestrial vegetation. Thus, there are strong hydrologic constraints to a reliance on biofuel energy produced with water from the present because the conversion from fossil fuels to biofuels would have a disproportionate and unsustainable impact on the modern water. By using fossil fuels to meet today's energy needs, we are virtually using water from a geological past. The water cycle is insufficient to sustain the production of the fuel presently consumed by human societies. Thus, non-fuel-based renewable energy sources are needed to decrease mankind's reliance on fossil fuel energy without placing an overwhelming pressure on global freshwater resources.

  18. [Medicine in ancient Mesopotamia - part 2].

    Science.gov (United States)

    Martins E Silva, J

    2010-01-01

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

  19. Chinese Companies in Switzerland

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available In recent years, some of China’s leading firms have made headlines with their European expansion, by either opening new facilities or by acquiring or merging with significant enterprises in Europe. The goal of this paper is to contribute to the existing literature by examining Chinese enterprises expanding into Switzerland. The study also allows some conclusions for Chinese companies entering Central and Eastern Europe. We analyze via interviews the motivations of Chinese companies to expand into Switzerland as well as their behavior and the impediments in their internationalization process. Our findings show that Chinese companies fail to take advantage of certain benefits of western economies (such as open information and stable rule of law. To move forward efficiently, they should develop competence in dealing systematically with readily available market information, building professional networks that recognize a separation between business life and personal life, and managing their Chinese and foreign employees in the foreign cultural environment.

  20. The Chinese negotiation.

    Science.gov (United States)

    Graham, John L; Lam, N Mark

    2003-10-01

    Most Westerners preparing for a business trip to China like to arm themselves with a list of etiquette how-tos. "Carry a boatload of business cards," tipsters say. "Bring your own interpreter." "Speak in short sentences." "Wear a conservative suit." Such advice can help get companies in the door and even through the first series of business transactions. But it won't sustain the prolonged, year-in, year-out associations Chinese and Western businesses can now achieve. The authors' work with dozens of companies and thousands of American and Chinese executives over the past 20 years has demonstrated that a superficial adherence to etiquette rules gets executives only so far. They have witnessed communication breakdowns between American and Chinese businesspeople time and time again. The root cause: the American side's failure to understand the much broader context of Chinese culture and values, a problem that too often leaves Western negotiators flummoxed and flailing. American and Chinese approaches often appear incompatible. Americans see Chinese negotiators as inefficient, indirect, and even dishonest, while the Chinese see American negotiators as aggressive, impersonal, and excitable. Such perceptions have deep cultural origins. Yet those who know how to navigate these differences can develop thriving, mutually profitable, and satisfying business relationships. Four cultural threads have bound the Chinese people together for some 5,000 years, and these show through in Chinese business negotiations. They are agrarianism, morality, the Chinese pictographic language, and wariness of strangers. Most Western businesspeople often find those elements mysterious and confusing. But ignore them at any time during the negotiation process, and the deal can easily fall apart.

  2. 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 ancient Egypt as well as China between 3000 and 500 B. C. culminated each 500 years synchronously. No local events, confined to Egypt or China alone, can serve as an explanation. The rhythm of "dark ages" seems to continue beyond Egyptian and ancient Chinese history into the modern era and seems to be world-wide. It is a surprising fact, that this periodicity has been known already to the priests of Babylon, who ascribed this to the maleficient influence of 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

  3. Observation of Celestial Phenomena in Ancient China

    Sun, Xiaochun

    Because of the need for calendar-making and portent astrology, the Chinese were diligent and meticulous observers of celestial phenomena. China has maintained the longest continuous historical records of celestial phenomena in the world. Extraordinary or abnormal celestial events were particularly noted because of their astrological significance. The historical records cover various types of celestial phenomena, which include solar and lunar eclipses, sunspots, "guest stars" (novae or supernovae as we understand today), comets and meteors, and all kinds of planetary phenomena. These records provide valuable historical data for astronomical studies today.

    Full Text Available In Spanish Golden Age drama we come across all forms of the reception of ancient writers’ motifs: explicit (direct quotation of an ancient author, where the quotation may be more or less complete, or a clear allusion to it, implicit (where there is no explicit mentioning of the ancient source, however certain ancient elements are mentioned such as persons, places, historical circumstances, hidden (where there is no clear hint about a literary intervention in Antiquity or an imitation of the literary excerpt or motif, as well as direct imitation (aemulatio or adaptation (variatio. In the Renaissance and Baroque there are almost no motifs, which could not be taken over from Antiquity without a transformation or innovation. If there is a close correspondence to the ancient motif, it is generally sufficient simply to mention it or employ a side motif as an illustration of a similar situation without elaborating the motif further or weaving it more deeply into the supporting fabric of the dramatic work. The ancient authors who contribute the motifs are numerous and diverse: Vergil, the Roman elegists Propertius in Tibullus, the lyric poet Horace, the comedian Plautus, the stoic philosopher Seneca, the historian Tacitus, the novelist Apuleius, as well as Greek dramatist Aeschylus and stoic philosopher Epictetus. The genres, which are a source for the surviving ancient motifs in the Golden Age in the selected authors, include literary as well as not-literary forms: epic poetry, lyric, dramatics, philosophy and historiography.

    Contents of trace elements in the reference material of ancient ceramics (KPS-1) were determined by means of activation analysis, using thermal neutron irradiation produced in nuclear reactor. KPS-1 favoured the analysis of ancient ceramics because it had not only many kinds of element but also appropriate contents of composition. The values presented here are reliable within the experimental precision, and have shown that the reference material had a good homogeneity. So KPS-1 can be used as a suitable reference material for the ancient ceramics analysis

    Ancient DNA is the name given to the degraded, fragmented, and chemically damaged biomolecules that can be recovered from archaeological remains of plants, animals, and humans. Where ancient human DNA has survived at archaeological sites, it can give valuable information and is especially useful for its potential to identify kinship, population affinities, pathogens, and biological sex. Here, we describe the operation of a microfluidic device for the sex identification of ancient DNA samples using an efficient sample handling process. DNA is extracted from powdered bone samples and abasic sites labeled with biotin. Streptavidin-coated superparamagnetic particles are used to isolate the labeled DNA prior to amplification of the Amelogenin sex marker.

    We are accustomed to thinking of the ambient mantle as being a well-stirred reservoir, which contains at most regions of stored subducted slabs and "plums" containing lithophile trace element enrichments. What is forgotten in all of this is that the main process of formation of heterogeneities is a negative one - generating 10x more depleted mantle at any given moment than it does oceanic crust. Because the volume of lithosphere subducted over Earth history is so large, it has always been assumed that the process of subduction and convective mixing re-homogenizes the depleted and enriched reservoirs about as fast as it produces them. What if it doesn't? Our primary means of studying mantle heterogeneity however is basalts. Direct study of the mantle entails observations on xenoliths, ophiolites and orogenic lherzolites, and abyssal peridotites. The latter have the inherent problems of being melting residues, associated with fracture zones, are highly serpentinized and rare. The arctic ridge system gives us a unique perspective on the mantle, and samples we have recovered there are relatively free from these problems. Due to the slow spreading rate, which apparently severely limits the melt productivity, the thickest crust in the Arctic ridge system is approximately "normal". The most common crust is about half thickness and there are large expanses with no crust at all, in the sense of Hess, 1962, exposing mantle peridotite in the floor of extensive rift zones. We have shown Os isotopic evidence for the survival of ancient depletion signatures in Gakkel abyssal peridotites that apparently were not destroyed by subduction, convective stirring or resetting during magma genesis (Liu, et al., 2008). Additionally, preliminary Nd isotopic evidence suggests at least a 400Ma intact prehistory for these samples. Apparently, the low melt productivity on Gakkel Ridge has allowed the Gakkel mantle rocks to escape significant resetting due to melt interaction. This implies a

    2009-01-01

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

    Imitated GE ware was one of the most famous products of Jingdezhen porcelain field in Ming dynasty (AD 1368-1644). The exterior features of its body and glaze are very marvelous. Black foot, purple mouth and crazing glaze are the main features of imitated GE ware. Until now, the key conditions of resulting these features are not clearly identified. In order to find the critical elements for firing these features, instrumental neutron activation analysis (INAA) and wavelength-dispersive X-ray fluorescence (WDXRF) were used to determine the element abundance patterns of imitated GE ware body and glaze. The experimental data was compared with that of imitated Longquan celadon and of Longquan celadon. The analytical results indicated that Fe, Ti and Na were the critical elements. The body of imitated GE ware which contains high Fe and Ti are the basic conditions of firing its black body, black foot and purple mouth. The glaze of imitated GE ware which contains high Na is the main condition of producing its crazing glaze. Na is the critical element which enlarges the difference in expansion coefficients between the glaze and body of imitated GE ware. Furthermore, Zijin soil was added into kaolin to make the body rich in Fe and Ti. And something which was rich in Na was used to produce crazing glaze in the manufacturing process of imitated GE ware

  15. Studing cranial vault modifications in ancient Mesoamerica.

    Tiesler, Vera

    2012-01-01

    The artificial modification of infant cranial vaults through massages or by means of constriction and compression devices constitutes a readily visible, permanent body modification that has been employed cross-culturally to express identity, ethnicity, beauty, status and gender. For those ancient societies that staged head shaping, these cultural correlates may be ascertained by examining cranial shapes together with other data sets from the archaeological record. Studies of skulls modified for cultural reasons also provide important clues for understanding principles in neural growth and physiopathological variation in cranial expansion. This paper focuses on head shaping techniques in Mesoamerica, where the practice was deeply rooted and widespread before the European conquest. It provides a comprehensive review of the Mesoamericanistic research on shaping techniques, implements and taxonomies. An up-dated, interdisciplinary examination of the physiological implications and the cultural meanings of artificially produced head shapes in different times and culture areas within Mesoamerica leads to a discussion of the scope, caveats, and future directions involved in this kind of research in the region and beyond.

  16. Heaven and Earth in Ancient Greek Cosmology

    Science.gov (United States)

    Couprie, Dirk L.

    The archaic world picture, the picture of a flat earth with the dome of the heaven vaulted above it, on which the celestial bodies are attached, is the basic world picture of many ancient cultures. Here "world picture" means the conception of the visible universe, not including all kinds of mythical or religious representations of what was imagined to be "under the earth." This archaic world picture (and also its penetration by a curious head) is beautifully rendered in a picture that is often thought to belong to the Renaissance period but was actually drawn in 1888 A.D. on the instructions of the famous French astronomer and popularizer Camille Flammarion (Fig. 1.1). The drawing refers to a story about Archytas (428-347 B.C.), who is supposed to have asked whether it would be possible to put a hand or a stick out of the heavens (DK 47A24). We will return to the implications of this question in the last chapter of this book.

  17. Cases of Trephination in Ancient Greek Skulls

    2012-01-01

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

    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.

    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.

    The characterization of biomolecules from ancient samples can shed otherwise unobtainable insights into the past. Despite the fundamental role of transcriptomal change in evolution, the potential of ancient RNA remains unexploited – perhaps due to dogma associated with the fragility of RNA. We hypothesize that seeds offer a plausible refuge for long-term RNA survival, due to the fundamental role of RNA during seed germination. Using RNA-Seq on cDNA synthesized from nucleic acid extracts, we validate this hypothesis through demonstration of partial transcriptomal recovery from two sources of ancient maize kernels. The results suggest that ancient seed transcriptomics may offer a powerful new tool with which to study plant domestication. PMID:23326310

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

    Science.gov (United States)

    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.

  7. Ancient Land Routes On The Paximadhi Peninsula, Karystos, Euboea

    Keller, D.; Hom, E.

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

    In a 1st attempt to identify an implicit theory of leadership among Chinese people, the authors developed the Chinese Implicit Leadership Scale (CILS) in Study 1. In Study 2, they administered the CILS to 622 Chinese participants from 5 occupation groups, to explore differences in perceptions of leadership. Factor analysis yielded 4 factors of leadership: Personal Morality, Goal Efficiency, Interpersonal Competence, and Versatility. Social groups differing in age, gender, education level, and occupation rated these factors. Results showed no significant gender differences, and the underlying cause for social group differences was education level. All groups gave the highest ratings to Interpersonal Competence, reflecting the enormous importance of this factor, which is consistent with Chinese collectivist values.

    In this study, the origin and causes of cooked traditional Chinese medicine powder were reviewed, and a comprehensive analysis was made for the time background of modern traditional Chinese medicine formula granules and the future development trend, in order to provide reference for application and promotion of traditional Chinese medicine formula granules. By reference to ancient medical books of previous dynasties, a system review was conducted for infancy, formation, maturity and transition of cooked traditional Chinese medicine powder, and a comprehensive analysis was made for the six factors of cooked traditional Chinese medicine powder's maturity in the Song Dynasty. Efforts were made to collect domestic and foreign research literatures of modern formula granules, understand the detailed development, and conduct an objective analysis of the current clinical application of modern formula granules. According to the comparative analysis for the application characteristics of cooked traditional Chinese medicine powder and modern formula granules, ①the popularity of cooked traditional Chinese medicine powder in the Song Dynasty has six factors: soaring numbers of medical students and medical practitioners, high medical expenses due to huge army, rapid population growth, frequent epidemics and increasing diseases, and insufficient finances of central and local governments. ②On the basis of clinical application characteristics of traditional Chinese medicine formula granules, traditional Chinese medicine formula granules contain extracted and concentrated effective components, which guarantee the curative effect, meet modern people's demands for "quick, simple and convenience" traditional Chinese medicine decoctions, show a relatively high cost performance; however, formula granules are restricted by their varieties and lack unified quality control standards, and single-extract formula granules have not synergy and attenuation effects of combined traditional

Part one: the energy sector in China. Due to the economic development of the country this sector is flourishing and reaches an average growth rate of 9% per year. More than fifty per cent of the power plants being built in the world, are located in China. The electricity production stems by far from fossil energies (>80%) but this part is expected to decrease to reach 70% in 2020. Part 2: the Chinese nuclear program. This program is dual: the massive deployment of chinese improved reactors of second generation (the construction of 6 CPR1000 reactors will be launched each year) and the import and assimilation of reactors of the third generation: 4 AP1000 and 2 EPR are being built. Part 3: the organization of the Chinese nuclear sector. The main actors are CNNC (China National Nuclear Corporation), CGNPC (China Guangdong Nuclear Power Corporation), CPI (China Power Investment Corporation), SNPTC (State Nuclear Power Technology Corporation). The main 5 Chinese suppliers are also presented. Part 4: The role of EDF. Today's EDF role is multiple: to be active in the Chinese nuclear program, to go beyond technical assistance to reach partnership, to invest in Chinese power plants, to promote cooperation between French and Chinese actors of the nuclear industry. A lot of joint ventures have been created. Part 5: the Taishan project. Taishan is a coastal site near Macao in the Guangdong province in which 2 EPR are being built, the first concrete was cast in october 2009, 52 months of construction are scheduled and the first unit will be commissioned in end 2013 while the second commissioning is planned for end 2014.

    China may be on the tipping point of explosive global growth. In response to changes in the global economy and an economic slowdown domestically, hundreds of thousands of Chinese SMEs are being encouraged to “go global” by their central and local governments. To a Chinese company, going global requires the expansion of its existing business in other countries or the development of new ventures with partners operating in other countries. Explosive growth in China may be possible, but it will d...

    Most genetic studies of Holocene fauna have been performed with ancient samples from dry and cold regions, in which preservation of fossils is facilitated and molecular damage is reduced. Ancient DNA work from tropical regions has been precluded owing to factors that limit DNA preservation (e.g. temperature, hydrolytic damage). We analysed ancient DNA from rodent jawbones identified as Ototylomys phyllotis, found in Holocene and Late Pleistocene stratigraphic layers from Loltún, a humid tropical cave located in the Yucatan peninsula. We extracted DNA and amplified six short overlapping fragments of the cytochrome b gene, totalling 666 bp, which represents an unprecedented success considering tropical ancient DNA samples. We performed genetic, phylogenetic and divergence time analyses, combining sequences from ancient and modern O. phyllotis, in order to assess the ancestry of the Loltún samples. Results show that all ancient samples fall into a unique clade that diverged prior to the divergence of the modern O. phyllotis, supporting it as a distinct Pleistocene form of the Ototylomys genus. Hence, this rodent's tale suggests that the sister group to modern O. phyllotis arose during the Miocene-Pliocene, diversified during the Pleistocene and went extinct in the Holocene. © 2014 The Author(s) Published by the Royal Society.

  1. Roots of political corruption in ancient history

    2016-01-01

    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.'.

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

    A number of coins of Hindu Shahis Dynasty of Kabul (990-1015 A.D.) have been analysed using proton induced X-ray emission (PIXE) technique. The 3 MeV proton beam from the Pelletron Accelerator at the Institute of Physics, Bhubaneswar, India was used for the production of X-rays. The X-rays were detected by Si(Li) detector (FWHM=180 eV at 5.9 keV) placed at 90 deg. to the beam direction. For the reliable calibration of the analytical system, thin foils of Micromatter standards of Fe, CuS, KCl, and RbNO 3 were used. The computer code GUPIX was employed to get concentration of trace elements in these coins. The elements Ca, Ti, Cr, Fe, Ni, Zn, As, Sb, Pb, and Bi were detected in these coins along with the major component of Cu and Ag. The coins were classified in two groups, coins no. 3, 9, 10, 11, 13, 14, 15, 16, 18, 19 as copper or billon coins having major component of copper, while coins no. 6, 17, 20, 21, 22 as silver coins having the major component of silver. The first group seems to belong to lower denomination while the other group belongs to higher denomination coins. There is a strong positive correlation between lead and zinc and also a strong negative correlation between copper and silver. The weight of coins varied between 3.05 and 3.39 gram. The comparison of our results with that of the ores of various mines indicates that the source of copper in these coins is from Khetri mine in Rajasthan. Silver seems to come from Afghanistan since it is not reported to occur as a primary mineral in ancient India

  4. Why cauldrons come first: taxonomic transparency in the earliest Chinese antiquarian catalogues

    2014-12-01

    Full Text Available The term ‘antiquarianism’ is increasingly being deployed as an analytical heuristic for comparing different world traditions of thinking about old things. Central to almost all characterizations of “Chinese antiquarianism” is the construction of a pedigree stretching back to the inventories and catalogs of antiquities produced during the Northern Song dynasty (960-1127. Close comparison reveals significant ideological differences between the values implicit in the earliest Chinese inventories of two-dimensional inscriptions on metal and stone, and those underlying catalogues of three-dimensional antiquities like bronzes. By situating these differences within the wider intellectual milieu of the Northern Song, this essay explains how the unique ‘taxonomic transparency’ of ancient bronzes reinforced Neo-Confucianism’s conquest of the Chinese ideological landscape at the dawn of the second millennium.

    According to various authoritative sources, the English word "journal" was first used in the 16lh century, but the existence of the journal in its original meaning as a daily record can be traced back to Acta Diuma (Daily Events in ancient Roman cities as early as 59 B.C. This article documents the first appearance of Chinese daily records that were much early than 59 B.C.

    The evidence of the earlier Chinese daily records came from some important archaeological discoveries in the 1970's, but they were also documented by Sima Qian (145 B.C. - 85 B.C., the grand historian of the Han Dynasty imperial court. Sima's lifetime contribution was the publication of Shi Ji (史記 (The Grand Scribe's Records, the Records hereafter. The Records is a book of history of a grand scope.

    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

  7. Chinese Prayer Chant to the Goddess of Fertility

    Full Text Available The article examines the prayer chant to the Goddess of Fertility performed by a blind singer and accompanied by the stringed instrument banghu and foot castanets in the temple of the Spirit of the Tanshan Dong Yue mountain, in Puxian county Shangxi province of the Republic of China. The video of the chant was recorded in April 2011, during the days before the Temple festival in honor of Dong Yue, a tradition that has been revived in the modern China. We publish the text of the chant not only in the Russian translation but also in Chinese. There are three graphic variants of the Chinese text presented — in Chinese characters, in standardized Pinyin, and in transcribed Pinyin that gives an idea of the actual pronunciation and allows the reader to trace dialectical specificity of the song. The article includes the music of both the chant and the instrumental accompaniment together with their ethno-musicological characteristics. The musical structure of the instrument and the modal specificity attribute this piece to the musical style of Northern China. The Authors analyze the verse and the strafica of the chant. They argue that its metrical structure consists of couplets (except for the last three line stanza, with instrumental wagering played in between that is characteristic of the ancient Chinese lyrics. The analysis of the text’s contents and imagery reveals that it reflects popular notions of Songzi nannan, the Goddess of Fertility. It also shows that the chant dates back to the feudal China: it predicts the fate of the future son of the young couple that ordered the chant by describing his future life of the “official” and the “noble man,” the image that has been developed on the basis of Confucian canons within the two millennia of Chinese history.

  8. Abrasive supply for ancient Egypt revealed

    In the framework of the major research scheme 'Synchronization of Civilizations in the Eastern Mediterranean Region in the 2nd Millennium B.C' instrumental neutron activation analysis (INAA) was used to determine 30 elements in pumice from archaeological excavations to reveal their specific volcanic origin. In ancient time, the widespread pumiceous products of several eruptions in the Aegean region have been used as abrasive tools and were therefore popular trade objects. The correlation of such archaeological findings to a specific eruption of known age would therefore allow to certify a maximum age of the respective stratum ('dating by first appearance'). Pumices from the Aegean region can easily be distinguished by their trace element distribution patterns. This has been shown by previous studies of the group. The elements Al, Ba, Ca, Ce, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mn, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, Ti, U, V, Yb, Zr and Zn were determined in 16 samples of pumice lumps from excavations in Tell-el-Dab'a and Tell-el-Herr (Egypt). Two irradiation cycles and five measurement runs were applied. To show the accuracy of the results obtained, typical samples of the most important pumice sources in the Aegean region, particularly from Milos, Nisyros, Kos and Thera were analyzed together with the Egyptian samples of unknown origin. A reliable identification of the samples is achieved by comparing these results to the database compiled in previous studies. The geographical positions of these islands are shown. Within the error range, most of the elements determined in typical representatives of Milos, Nisyros, Kos and Santorini were in perfect agreement with values from the literature. On the basis of the Cluster graphics presented, it is possible to relate unknown pumice to its primary source, just by comparing the relation of a few elements, like Ta-Eu and Th-Hf. One concludes that all samples except one can be related to the Minoan eruption of Thera

  9. Magnetite Authigenesis and the Ancient Martian Atmosphere

    Although the Curiosity rover has documented lacustrine sediments at Gale Crater, how liquid water became physically stable is unknown. The early Martian atmosphere is thought to have been dominated by CO2 [1], but the Curiosity rover has provided only ambiguous detections of carbonate minerals at abundances significantly less than 1 wt. % [2, 3], and climate models indicate that in the absence of additional components, multi-bar CO2 atmospheres could not have maintained surface temperatures above freezing. To constrain the composition of the ancient Martian atmosphere, we experimentally investigated the nucleation and growth kinetics of authigenic Fe(II)-minerals in Gale Crater mudstones. Experiments show that as basaltic waters experience pH increases above 8.0, a series of anoxic mineral transformations generates magnetite in days. Electrochemical and dissolved gas analyses show that one stage of this process, the conversion of Fe(OH)2 to green rust, generates H2(g). Experiments including dissolved CO2 show that, despite magnetite formation, Fe(II)-carbonate does not nucleate until significant supersaturation is reached, at PCO2 levels far above previous estimates. Our experimental observations imply that Gale Crater lakes could have been in contact with a CO2-rich atmosphere. In addition, geochemical calculations show that groundwater infiltration into lacustrine sediments triggered magnetite and H2(g) generation at Gale Crater (instead of Fe(II)-carbonate cementation). Groundwater infiltration is consistent with data from the Sheepbed member mudstones, and deep-water mudstones of the Murray formation, both of which contain abundant authigenic magnetite [2, 4]. Low temperature H2 production may have provided a globally significant but transient feedback for stabilizing liquid water on early Mars. Data collected to date by the Curiosity rover are consistent with both estimated timescales and climatic shifts associated with H2-induced warming. Low temperature H2

  10. 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 BACKGROUND: A major challenge for ancient DNA (aDNA studies on insect remains is that sampling procedures involve at least partial destruction of the specimens. A recent extraction protocol reveals the possibility of obtaining DNA from past insect remains without causing visual morphological damage. We test the applicability of this protocol on historic museum beetle specimens dating back to AD 1820 and on ancient beetle chitin remains from permafrost (permanently frozen soil dating back more than 47,000 years. Finally, we test the possibility of obtaining ancient insect DNA directly from non-frozen sediments deposited 3280-1800 years ago -- an alternative approach that also does not involve destruction of valuable material. METHODOLOGY/PRINCIPAL FINDINGS: The success of the methodological approaches are tested by PCR and sequencing of COI and 16S mitochondrial DNA (mtDNA fragments of 77-204 base pairs (-bp in size using species-specific and general insect primers. CONCLUSION/SIGNIFICANCE: The applied non-destructive DNA extraction method shows promising potential on insect museum specimens of historical age as far back as AD 1820, but less so on the ancient permafrost-preserved insect fossil remains tested, where DNA was obtained from samples up to ca. 26,000 years old. The non-frozen sediment DNA approach appears to have great potential for recording the former presence of insect taxa not normally preserved as macrofossils and opens new frontiers in research on ancient biodiversity.

    2013-07-26

    Amputations, or the removal of limbs at different levels, have been performed since the ancient times. The first reports of amputations originate from the ancient ruins in Egypt, where primitive prosthetic toes were found in the tombs of the Pharaohs. In Europe, during the period of ancient Greece and Rome, various examples of amputations were described on amphoras and mosaics. During the middle ages, the body was marginalized and replaced by the worship of human spirituality. As a result reports of amputations from that time period are scarce. True development of amputation and prosthetic techniques took place during the Renaissance and centuries that followed. Present-day indications for amputation are similar to those utilized in the ancient times. The greatest development of limb amputation techniques and prosthetic methods began in the 20th century and continues to this day. Despite the development of new techniques in prosthetics, many solutions have their roots in designs originating in the ancient times and differ only in their structural design.

    Full Text Available Members of the Jesuit Order came to Ljubljana in 1597, founding a »gymnasium« and later expanding it with a semi-university. In contrast to certain other orders, they fostered the classics, as is evidenced by their teaching, scholarly research, and literary composition. The scholarly work of the Jesuits active in present-day Slovenia was mostly concentrated on ancient philosophy, as is shown in the second section of this paper. Their teaching, on the other hand, included both classroom lessons and more creative activities, such as the writing and staging of school plays. The Jesuit school system with its six gymnasium classes is described in the first section of the paper, and the school curriculum (based almost exclusively on the teaching of Latin literature and methods in the third. The fourth section presents the documents relating to the final gymnasium examinations in ancient literature which took place in Ljubljana, with a survey of the contents of the questions. The fifth section outlines the characteristics of Jesuit school drama. The plays performed in Ljubljana are lost, but, judging by the preserved titles and synopses, ancient themes appear to have been relatively rare. Nevertheless, the paper succeeds in isolating seventeen works (discussed in the sixth section which must have either utilised plots from ancient literature or drawn inspiration from ancient stock characters and rhetoric.

    As far as the rights of consumers are concerned, the International Organization of Consumer's Union (IOCU) in 1983 has specified about the eight rights of a consumer. The Consumer Protection Act (CPA), 1986 then prescribed six "Rights of Consumers," which are protected under the act. However, these rights can be observed in the ancient Indian texts such as Brihat-trayee , Narad Smruti , and Kautilya Arthashastra ., in the form of rights given to patients. For the purpose of present study, the implemented methodology includes - (1) study of the consumer rights described by IOCU and CPA, (2) detailed review of literature for observance of replication of these consumer rights in the ancient Indian texts and (3) a comparative study of the present consumer rights with the rights of patients observed in ancient Indian texts. This study shows that the substance of consumer rights is not a recent evolution, but the foundation of these rights has been laid well beforehand in the ancient times, which were provided to the patients by medical profession as well as by the rulers. The current scenario of protection of consumer rights is the replication of this ancient practice only.

    Full Text Available This paper presents an overview on the sustainability of ancient water supply systems in Jerusalem from the Chalcolithic period (4500–3200 B.C. until the present time. Archaeological evidences and landscape settings were applied utilizing all available and accessible literature relevant to ancient water resources management in Jerusalem. Irrigated agriculture was practiced for many centuries in this region, hence sustainable water supply facilities were erected, including well developed aqueducts, water harvesting pools and irrigation channels for water storage and landscaping purposes. To cope with seismic events, soil subsidence and water leakage, ancient water engineers and architects applied innovative construction methods for the erection of water pools, channels and aqueduct systems. Ancient water supply systems in Jerusalem are valuable treasures of past civilizations and crucial urban environmental facilities and their protection is consistent with sustainable development principles. Effective environmental assessment as a decision-making process for sustainable development can be applied to preserve threatened ancient water facilities from major development proposals and urban infrastructure projects in Jerusalem.

  20. Chinese Medicine: A Cognitive and Epistemological Review

    Ben Kavoussi

    2007-01-01

    Full Text Available In spite of the common belief that Chinese natural philosophy and medicine have a unique frame of reference completely foreign to the West, this article argues that they in fact have significant cognitive and epistemic similarities with certain esoteric health beliefs of pre-Christian Europe. From the standpoint of Cognitive Science, Chinese Medicine appears as a proto-scientific system of health observances and practices based on a symptomological classification of disease using two elementary dynamical-processes pattern categorization schemas: a hierarchical and combinatorial inhibiting–activating model (Yin-Yang, and a non-hierarchical and associative five-parameter semantic network (5-Elements/Agents. The concept-map of the five-parameter model amounts to a pentagram, a commonly found geomantic and spell casting sigil in a number of pre-Christian health and safety beliefs in Europe, to include the Pythagorean cult of Hygieia, and the Old Religion of Northern Europe.

    In spite of the common belief that Chinese natural philosophy and medicine have a unique frame of reference completely foreign to the West, this article argues that they in fact have significant cognitive and epistemic similarities with certain esoteric health beliefs of pre-Christian Europe. From the standpoint of Cognitive Science, Chinese Medicine appears as a proto-scientific system of health observances and practices based on a symptomological classification of disease using two elementary dynamical-processes pattern categorization schemas: a hierarchical and combinatorial inhibiting-activating model (Yin-Yang), and a non-hierarchical and associative five-parameter semantic network (5-Elements/Agents). The concept-map of the five-parameter model amounts to a pentagram, a commonly found geomantic and spell casting sigil in a number of pre-Christian health and safety beliefs in Europe, to include the Pythagorean cult of Hygieia, and the Old Religion of Northern Europe. This non-hierarchical pattern-recognition archetype/prototype was hypothetically added to the pre-existing hierarchical one to form a hybrid nosology that can accommodate for a change in disease perceptions. The selection of five parameters rather than another number might be due to a numerological association between the integer five, the golden ratio, the geometry of the pentagram and the belief in health and wholeness arising from cosmic or divine harmony. In any case, this body of purely empirical knowledge is nowadays widely flourishing in the US and in Europe as an alternative to Western Medicine and with the claim of being a unique, independent and comprehensive medical system, when in reality it is structurally-and perhaps historically-related to the health and safety beliefs of pre-Christian Europe; and without the prospect for an epistemological rupture, it will remain built upon rudimentary cognitive modalities, ancient metaphysics, and a symptomological view of disease.

  2. Buddhism in Sarnath: An Account of Two Chinese Travellers

    Full Text Available This paper aims to draw the religious life in Sarnath (and Varanasi as accounted by the Chinese travellers—Fa-Hien and Hiuen-tsang. The accounts not only talk about the stupas, pillars, statues built by King Ashoka; vihars and monks (bhikshus living in those vihars but also contain the first preachings of Lord Buddha, establishment of Sangha and the story of Mrigajataka that remain significant. With the increased popularity of Buddha dharma in China, the Chinese were attracted towards travelling to India. They came to India mainly with the intentions to visit the places related to the fond memories of Lord Buddha, to study the Buddha religion and philosophy and carry the copies of the Buddhist compositions. Fa-Hien and Hiuen-tsang occupy significant places among these Chinese travellers. These accounts can be associated with ancient history as well as with historical geography, religion and philosophy. While Fa-hien in his journey details had described about the Buddha Empire, Hiuen-tsang highlighted the civilisation of India and its cultural landscape, albeit it has been often accepted by the historians that these accounts of their journeys should be considered as significant only when they are backed by historical evidences. They opine that these travellers were mainly influenced by the Buddha dharma and therefore, their accounts are liable to containing exaggerated journey details. It is true that the journey details contain few imaginary instances; nevertheless, these accounts have been validated by the remnants, stupas and vihars at the sites.

  4. Acoustical Masks and sound aspects of Ancient Greek Theatre

    Full Text Available It is impossible to imagine the ancient Greek theatre without the mask, whether it is tragedy, comedy or satyr plays. All theatrical forms that developed in Athens during the 6th and 5th centuries BC were forms of masked drama. The mask was an organic element in this new form called theatre because the mask is the medium per excellence for the embodiment of the Other and participates in the creation of the stage as a site of the dialogue between the Self andthe Other. But the mask was an organic element of the theatre because in ancient Greek theatre the mask is organically connected through its facial appearance to the ecstatic cries found in the dramatic texts and to the theatre space through its acoustical form. Acoustics permeated all aspects of the ancient Greek theatre and was a way to create even better participation for the audience enhancing its acoustico-visual and synaesthetic experience.

    2015-12-01

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

    Samples of Sorori ancient rice were excavated in 1998 from the Sorori Paleolithic site located at Sorori, Oksan-myeon, Cheong-won County in Chungcheongbuk-do, Korea. We have made new radiocarbon measurements for Sorori samples in 2009 at the NSF Arizona AMS Laboratory. Both ancient rice samples and surrounded peat from the Sorori site were dated. The AMS results confirmed that the ages of the rice and peat soil were 12,520 {+-} 150 and 12,552 {+-} 90 BP, respectively. These radiocarbon ages are consistent with the previously published data of quasi rice measured at Seoul National University and confirm that the Sorori rice is the oldest ancient rice currently reported.

    Ancient Iranian silver coins minted in various parts of the ancient Iran from Transoxiana to Mesopotamia over a time span of 460 years (247BC-208AD) during Parthians dynasty were analysed by PIXE with a 2.2 MeV proton beam. Forty seven silver coins owned by Tamashagah-e-Pool (museum of money) in Tehran were examined in this study. The possible correlation between the composition of coins and the minting time or the minting location of coins has been the prime objective of the present study. Elemental analysis of ancient coins could also reveal the direct relation with the political and economical situation and also with the metallurgy of the minting time. Results on the contents of principal component elements (Fe, Ni, Cu, As, Br, Ag, Sn, Sb, Ba, Au and Pb) are presented and discussed. (author)

    Calcified dental plaque (dental calculus) preserves for millennia and entraps biomolecules from all domains of life and viruses. We report the first high-resolution taxonomic and protein functional characterization of the ancient oral microbiome and demonstrate that the oral cavity has long served as a reservoir for bacteria implicated in both local and systemic disease. We characterize: (i) the ancient oral microbiome in a diseased state, (ii) 40 opportunistic pathogens, (iii) the first evidence of ancient human-associated putative antibiotic resistance genes, (iv) a genome reconstruction of the periodontal pathogen Tannerella forsythia, (v) 239 bacterial and 43 human proteins, allowing confirmation of a long-term association between host immune factors, “red-complex” pathogens, and periodontal disease, and (vi) DNA sequences matching dietary sources. Directly datable and nearly ubiquitous, dental calculus permits the simultaneous investigation of pathogen activity, host immunity, and diet, thereby extending the direct investigation of common diseases into the human evolutionary past.

    2008-01-01

    Vision testing in ancient times was as important as it is today. The predominant vision testing in some cultures was the recognition and identification of constellations and celestial bodies of the night sky. A common ancient naked eye test used the double star of the Big Dipper in the constellation Ursa Major or the Big Bear. The second star from the end of the handle of the Big Dipper is an optical double star. The ability to perceive this separation of these two stars, Mizar and Alcor, was considered a test of good vision and was called the "test" or presently the Arab Eye Test. This article is the first report of the correlation of this ancient eye test to the 20/20 line in the current Snellen visual acuity test. This article describes the astronomy, origin, history, and the practicality of this test and how it correlates with the present day Snellen visual acuity test.

  12. Quantum gravity and taoist cosmology: Exploring the ancient origins of phenomenological string theory.

    Science.gov (United States)

    Rosen, Steven M

    2017-12-01

    This paper carries forward the author's contribution to PBMP's previous special issue on Integral Biomathics (Rosen 2015). In the earlier paper, the crisis in contemporary theoretical physics was described and it was demonstrated that the problem can be addressed effectively only by shifting the foundations of physics from objectivist Cartesian philosophy to phenomenological philosophy. To that end, a phenomenological string theory was proposed based on qualitative topology and hypercomplex numbers. The current presentation takes this further by delving into the ancient Chinese origin of phenomenological string theory. First, we discover a deep connection between the Klein bottle, which is crucial to the theory, and the Ho-t'u, an old Chinese number archetype central to Taoist cosmology. The two structures are seen to mirror each other in expressing the curious psychophysical (phenomenological) action pattern at the heart of microphysics. But tackling the question of quantum gravity requires that a whole family of topological dimensions be brought into play. What we find in engaging with these structures is a closely related family of Taoist forebears that, in concert with their successors, provide a blueprint for cosmic evolution. Whereas conventional string theory accounts for the generation of nature's fundamental forces via a notion of symmetry breaking that is essentially static and thus unable to explain cosmogony successfully, phenomenological/Taoist string theory is guided by the dialectical interplay between symmetry and asymmetry inherent in the principle of synsymmetry. This dynamic concept of cosmic change is elaborated on in the three concluding sections of the paper. Here, a detailed analysis of cosmogony is offered, first in terms of the theory of dimensional development and its Taoist (yin-yang) counterpart, then in terms of the evolution of the elemental force particles through cycles of expansion and contraction in a spiraling universe.

    Full Text Available There are various plant types in Tlos Ancient City of Fethiye district in the Province of Mugla, a city where different residential ruins of Lycia Civilization starting from Classical Age until Byzantine Period. Tlos is an important city in West-Lycia and is situated right on the control point of Lycia Way. Hedera helix L. is one of the plants living in this area, which attracts the attention as it mostly harms the ancient ruins. One of the most important reasons why Hedera helix L. is growing commonly in this region is the perfect ecological circumstances for the growth of this plant of the location where this ancient city is situated in. Additionally the fact that the ruins of the city are left on their fate, is another perfect circumstance for the Hedera helix L. to grow. Climbing or creeping stems of Hedera helix L. stick easily to the objects it touches and encircle them. Due to this characteristic, the walls of the ancient city are covered by this plant. Nevertheless, Hedera helix L. does not only harm the ancient constructions and natural rocks but also woody plants. The harm caused by dried out or cut Hedera helix L. are more than the harm caused by them when they were untouched. The subject of this study is to prove the shape and level of the harm caused by Hedera helix L. on ancient ruins of Tlos. At the same time, this study will underline the fighting methods against Hedera helix L. by comparing similar studies in other countries. Knowledge collected after this study will offer an insight into the excavation and restoration studies undertaken in all Mediterranean countries.

    Deacy, Susan; McHardy, Fiona

    2013-10-24

    Previous studies of ancient Greek examples of uxoricide in pregnancy have concluded that the theme is used to suggest tyrannical abuse of power and that the violence is a product of the patriarchal nature of ancient society. This article uses evolutionary analyses of violence during pregnancy to argue that the themes of sexual jealousy and uncertainty over paternity are as crucial as the theme of power to an understanding of these examples and that the examples can be seen as typical instances of spousal abuse as it occurs in all types of society.

  8. Chinese Entrepreneurs Go Global

    Directory of Open Access Journals (Sweden)

    Daniel Zhou

    2012-02-01

    Full Text Available China may be on the tipping point of explosive global growth. In response to changes in the global economy and an economic slowdown domestically, hundreds of thousands of Chinese SMEs are being encouraged to “go global” by their central and local governments. To a Chinese company, going global requires the expansion of its existing business in other countries or the development of new ventures with partners operating in other countries. Explosive growth in China may be possible, but it will depend on an appropriate strategy for going global. For a country that has firmly established itself as an international manufacturing hub, going global requires a shift in its entrepreneurial capacity, which is the focus of this article. We first assess the current situation in China to understand its current entrepreneurial focus and capacity, as well as the impetus for change. Next, we contrast the Kirznerian and Schumpeterian views of entrepreneurship to illustrate that – to go global – Chinese entrepreneurs must shift from an emphasis on exploiting pricing inefficiencies (i.e., Kirznerian entrepreneurship to an emphasis on innovation (i.e., Schumpeterian entrepreneurship. Finally, we examine unique characteristics of the business environment and culture in China, which are likely to impact the ability of Chinese entrepreneurs to go global.

    Japanese and Chinese share virtually identical morphographic characters invented in ancient China. Whereas modern Chinese retained the original morphographic functionality of these characters (hanzi), modern Japanese utilizes these characters (kanji) as complex syllabograms. This divergence provides a unique opportunity to systematically investigate brain strategies for sentence reading in Japanese-Chinese bi-literates. Accordingly, we investigated brain activation associated with Japanese and Chinese reading in 14 native Japanese speakers literate in Mandarin and 14 native Mandarin speakers literate in Japanese using functional magnetic resonance imaging performed on a 3T system. The activation pattern exhibited clearly distinct features specific for each language. Regardless of the subject's native language literacy, Chinese reading activated an area significantly larger than Japanese reading, suggesting that brain processes involved in Chinese reading were much more complex than Japanese reading. Significant recruitment of corresponding cortical areas in the right hemisphere with Chinese reading was also apparent. The activation patterns associated with Japanese reading by native Japanese literates was highly consistent with previous reports, and included the left inferior frontal gyrus (IFG), left posterior temporal lobe (PTL), and left ventral premotor cortex (PMv). The activation pattern associated with Chinese reading by native Chinese literates was also highly consistent with previous reports, namely the left IFG, left PTL, left PMv, left anterior temporal lobe (ATL), and bilateral parieto occipital lobes (LPOL). The activation pattern associated with Chinese reading by native Japanese literates was virtually identical to that by native Chinese literates, whereas the activation pattern associated with Japanese reading by native Chinese literates was signified by additional activation of LPOL compared to that by native Japanese literate. The study indicated

    2010-01-01

    Full Text Available More and more patients have been diagnosed as having chronic fatigue syndrome (CFS in recent years. Western drug use for this syndrome is often associated with many side-effects and little clinical benefit. As an alternative medicine, traditional Chinese medicine (TCM has provided some evidences based upon ancient texts and recent studies, not only to offer clinical benefit but also offer insights into their mechanisms of action. It has perceived advantages such as being natural, effective and safe to ameliorate symptoms of CFS such as fatigue, disordered sleep, cognitive handicaps and other complex complaints, although there are some limitations regarding the diagnostic standards and methodology in related clinical or experimental studies. Modern mechanisms of TCM on CFS mainly focus on adjusting immune dysfunction, regulating abnormal activity in the hypothalamic-pituitary-adrenal (HPA axis and serving as an antioxidant. It is vitally important for the further development to establish standards for ‘zheng’ of CFS, i.e. the different types of CFS pathogenesis in TCM, to perform randomized and controlled trials of TCM on CFS and to make full use of the latest biological, biochemical, molecular and immunological approaches in the experimental design.

    2017-03-01

    Digital imaging has become a very important technique in the conservation of cultural art relics because it can nondestructively acquire the color and spectral image of cultural art relics for different applications. Imaging accuracy is one of the key factors in digital protection of cultural art relics. In order to improve the color and spectral accuracy for digital imaging of cultural art relics, the idea of making the specific color charts for different kinds of artworks is presented. Taking ancient Chinese Dunhuang murals as the specific object of study, a prototype pigments color chart of the Dunhuang murals (DCC), containing a six-step grayscale and 30 colored pigment samples, is made to investigate its pigment types and painting techniques. Under the premise of considering the difference in the number of samples in color charts, the DCC is tested and compared with the classic and widely used standard Macbeth colorchecker (CC) in two aspects: color correction for RGB imaging and spectral reconstruction for spectral imaging. The results show that the prototype pigments color chart is more effective and exhibits superior performance to the CC in both aspects for digital conservation of the Dunhuang murals.

    Earthworms have provided ancient cultures with food and sources of medicinal cures. Ayurveda, traditional Chinese medicine (TCM), and practices in Japan, Vietnam, and Korea have focused first on earthworms as sources of food. Gradually fostering an approach to potential beneficial healing properties, there are renewed efforts through bioprospecting and evidence-based research to understand by means of rigorous investigations the mechanisms of action whether earthworms are used as food and/or as sources of potential medicinal products. Focusing on earthworms grew by serendipity from an extensive analysis of the earthworm's innate immune system. Their immune systems are replete with leukocytes and humoral products that exert credible health benefits. Their emerging functions with respect to evolution of innate immunity have long been superseded by their well-known ecological role in soil conservation. Earthworms as inexpensive, noncontroversial animal models (without ethical concerns) are not vectors of disease do not harbor parasites that threaten humans nor are they annoying pests. By recognizing their numerous ecological, environmental, and biomedical roles, substantiated by inexpensive and more comprehensive investigations, we will become more aware of their undiscovered beneficial properties.

  4. High-resolution analysis of cytosine methylation in ancient DNA.

    Directory of Open Access Journals (Sweden)

    Bastien Llamas

    Full Text Available Epigenetic changes to gene expression can result in heritable phenotypic characteristics that are not encoded in the DNA itself, but rather by biochemical modifications to the DNA or associated chromatin proteins. Interposed between genes and environment, these epigenetic modifications can be influenced by environmental factors to affect phenotype for multiple generations. This raises the possibility that epigenetic states provide a substrate for natural selection, with the potential to participate in the rapid adaptation of species to changes in environment. Any direct test of this hypothesis would require the ability to measure epigenetic states over evolutionary timescales. Here we describe the first single-base resolution of cytosine methylation patterns in an ancient mammalian genome, by bisulphite allelic sequencing of loci from late Pleistocene Bison priscus remains. Retrotransposons and the differentially methylated regions of imprinted loci displayed methylation patterns identical to those derived from fresh bovine tissue, indicating that methylation patterns are preserved in the ancient DNA. Our findings establish the biochemical stability of methylated cytosines over extensive time frames, and provide the first direct evidence that cytosine methylation patterns are retained in DNA from ancient specimens. The ability to resolve cytosine methylation in ancient DNA provides a powerful means to study the role of epigenetics in evolution.

    The ability to design synthetic genes and engineer biological systems at the genome scale opens new means by which to characterize phenotypic states and the responses of biological systems to perturbations. One emerging method involves inserting artificial genes into bacterial genomes and examining how the genome and its new genes adapt to each other. Here we report the development and implementation of a modified approach to this method, in which phylogenetically inferred genes are inserted into a microbial genome, and laboratory evolution is then used to examine the adaptive potential of the resulting hybrid genome. Specifically, we engineered an approximately 700-million-year-old inferred ancestral variant of tufB, an essential gene encoding elongation factor Tu, and inserted it in a modern Escherichia coli genome in place of the native tufB gene. While the ancient homolog was not lethal to the cell, it did cause a twofold decrease in organismal fitness, mainly due to reduced protein dosage. We subsequently evolved replicate hybrid bacterial populations for 2000 generations in the laboratory and examined the adaptive response via fitness assays, whole genome sequencing, proteomics, and biochemical assays. Hybrid lineages exhibit a general adaptive strategy in which the fitness cost of the ancient gene was ameliorated in part by upregulation of protein production. Our results suggest that an ancient-modern recombinant method may pave the way for the synthesis of organisms that exhibit ancient phenotypes, and that laboratory evolution of these organisms may prove useful in elucidating insights into historical adaptive processes.

    This article deals with the history of medicine in the ancient Greece; from the cult of the God Asklepios, to the founder of the scientific rational medicine, Hippokrates. The humoral theory of Hippokrates is explained (the human body consists from four liquids) and his ideal of a physician's approach to a patient is emphasized. In the Hellenistic period the medical development continued in the Alexandria Medical School (Herofilos and Erasistratos). At first, not much attention was given to medicine and scientific health prevention in ancient Rome. Only 293 AD have physicians from Greece first been invited to Rome--e.g. Asklepiades. During the reign of C. lulius Caesar, foreigners, who engaged in medical practice, were granted Roman citizenship and thanks to a number of benefits the medical condition in Roman Empire blossomed. Medical clinics (iatreia), infirmaries (valetudinaria) and, under the influence of Christianity, hospitals were established. In the 2nd century AD ancient medicine reached its climax with physician Galenos, who created the entire system of medical science and became the most significant, but also last medical figure of ancient Rome.

  5. Constraints on the nature of the ancient lunar magnetic field

    International Nuclear Information System (INIS)

    Goswami, J.N.

    1976-01-01

    It is stated that many lunar rocks possess a stable component of natural remanent magnetisation with specific intensities of about 10 -6 emu/gm. Most of these rocks also have compaction ages > 3 x 10 9 yr. Ancient lunar surface magnetic fields of the order of 10 -2 to 1.2 gauss have been postulated to explain the observed remanent magnetisation, and interesting suggestions have been made concerning the origin of such high magnetic fields during the early history of the Moon. It has been proposed that an intrinsic dipolar field was acquired by the Moon during its initial stages of formation. Such a dipolar field could have resulted either from a primaeval magnetisation by an external field, or from the action of an ancient lunar dynamo. It is pointed out here that some constraints can be put on the origin and nature of the ancient lunar magnetic field by consideration of the observation of solar wind ions in lunar breccias with compaction ages > 3.2 x 10 9 yr. These observations rule out the hypothesis that external field magnetisation initiated the ancient lunar magnetic field. The lunar dynamo model is possible only if field reversal is introduced.

    Huynen, Leon; Millar, Craig D; Lambert, David M

    2012-08-01

    Recently two developments have had a major impact on the field of ancient DNA (aDNA). First, new advances in DNA sequencing, in combination with improved capture/enrichment methods, have resulted in the recovery of orders of magnitude more DNA sequence data from ancient animals. Second, there has been an increase in the range of tissue types employed in aDNA. Hair in particular has proven to be very successful as a source of DNA because of its low levels of contamination and high level of ancient endogenous DNA. These developments have resulted in significant advances in our understanding of recently extinct animals: namely their evolutionary relationships, physiology, and even behaviour. Hair has been used to recover the first complete ancient nuclear genome, that of the extinct woolly mammoth, which then facilitated the expression and functional analysis of haemoglobins. Finally, we speculate on the consequences of these developments for the possibility of recreating extinct animals. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
